Background: Preterm birth(PTB) is a primary cause of neonatal morbidity and mortality, the pathogenic mechanisms of PTB still remain largely unexplored. In the present study, we aimed to identify potential key genes and pathway associated with PTB by bioinformatics analysis. Methods: The GSE46510 dataset was obtained from GEO database. Differentially expressed genes (DEGs) were identified using the limma package in R software, the functional enrichment analysis was performed, and the protein-protein interaction (PPI) network was constructed by Cytoscape software. The network topology was analyzed using MCODE. Results: A total of 335 DEGs were identified from the dataset. The majority of up-regulated DEGs were significantly enriched in inflammatory response, while down-regulated DEGs were mainly enriched in mitotic nuclear division. The top 5 hub up regulated genes were ITGAM, IL1B, ITGAX, NFKB1, and SOCS3. Pathway analysis indicated enrichment in Cytokine-cytokine receptor interaction, signaling by Interleukins. The top 5 hub down regulated genes were CXCR4, ANAPC10, ANAPC4, UBE2V2, UBA3, Pathway analysis indicated enrichment in Ubiquitin mediated proteolysis, Phosphorylation of the APC/C. Conclusion: Our study indicated genes and pathways in PTB by bioinformatics analysis, which may provide novel insights for unraveling pathogenesis of PTB.
背景:早产(PTB)是新生儿发病和死亡的主要原因之一,其发病机制仍未得到充分研究。在本研究中,我们旨在通过生物信息学分析寻找与PTB相关的潜在关键基因和途径。方法:从GEO数据库获取GSE46510数据集。差异表达基因(differential expression genes, DEGs)通过R软件的limma软件包进行鉴定,功能富集分析,蛋白-蛋白相互作用(protein-protein interaction, PPI)网络通过Cytoscape软件构建。利用MCODE对网络拓扑结构进行了分析。结果:从数据集中共鉴定出335个deg。大部分上调的DEGs在炎症反应中显著富集,而下调的DEGs主要富集于有丝分裂核分裂中。前5位集线器上调基因为ITGAM、IL1B、ITGAX、NFKB1和SOCS3。途径分析表明细胞因子-细胞因子受体相互作用,白细胞介素信号通路富集。前5位的hub下调基因分别为CXCR4、ANAPC10、ANAPC4、UBE2V2、UBA3, Pathway分析显示在泛素介导的蛋白水解、APC/C磷酸化中富集。结论:我们的研究通过生物信息学分析发现了PTB的基因和通路,为揭示PTB的发病机制提供了新的思路。

For the first time in human history, obtaining a COVID-19 vaccine has become essential for the sustainability of our species. As an amazing product of collective ideation, remarkably safe and efficient vaccines have been invented, tested, distributed, and administered to the population on a voluntary basis. The fast-mutating individual behavior of the virus is probably guided by a similar goal of the sustainability of the species. With this commentary, we analyze and compare two means of sustainability through adaptability: collective ideation in the case of humans and individual mutations in the case of viruses - two very different species whose behaviors are driven by sustainability.

人类历史上第一次,获得COVID-19疫苗对我们物种的可持续性至关重要。作为集体思想的惊人产物,已经在自愿的基础上发明、测试、分发和向人口提供了非常安全和有效的疫苗。病毒快速变异的个体行为可能是由物种可持续性的类似目标所引导的。在这篇评论中,我们分析和比较了通过适应性实现可持续性的两种手段:人类的集体思维和病毒的个体突变——这是两种截然不同的物种,它们的行为都是由可持续性驱动的。

Background: Hysterectomy is world wide's second most commonly done gynecological surgery, second only to the caesarean section. There is no general consensus, however, about the optimal hysterectomy process. Hysterectomy may be achieved through different techniques such as stomach, vaginal and laparoscopic. The goal of the study is to explore whether the hysterectomy of minilaparotomy for benign uterine lesions may be a viable option to laparoscopic hysterectomy in terms of short-term operational and postoperative performance. Methods: 105 patients who were due to undergo complete hysterectomy for a benign uterine lesion were split into 3 categories according to their preference of therapeutic therapy method: group A (35 patients) minilaparotomy hysterectomy utilizing traditional sutures. Group B (35 patients) minilaparotomy hysterectomy utilizing bipolar vessel sealing procedure (Ligasure). Group C (35patients) laparoscopic hysterectomy using Ligasure. Result (s): The operating time in Group A (84.71 ± 9.91 minutes), group B (55.31 ± 7.81 minutes), while group C (94.81 ± 16.1 minutes).The duration until resumption of intestinal sounds in group C (12.31 ± 2.51 hours) in comparison to group A (17.41 ± 1.91 hours) and group B (16.51 ± 1.761 hours). Blood loss in group B (99.11 ± 30.81 ml), group A (130.31 ± 54.41 ml) and group C (136.61 ± 6.61 ml). The longest hospital stay occurred in group A (31.8 1± 5.71 hours) versus groups B (20.71 ± 2.51 hours) and C (19.31 ± 6.1 hours). The highest pain score was observed in group A (5.21 ± 1.11) versus groups B (3.81 ± 1.61) and C (3.71 ± 1.21). There was no significant difference in the incidence of intraoperative or postoperative complications. Conclusion (s): Less operational time and intraoperative blood loss were correlated with the usage of ligasure bipolar vessel sealing device in minilaparotomy hysterectomy, whereas it was comparable to laparoscopic hysterectomy in hospital stay and low morbidity postoperative pain scoring and a limited hospital stay. It can be an acceptable alternative to laparoscopic hysterectomy, suitable in areas without laparoscopic experience or facilities.
背景:子宫切除术是世界上第二常见的妇科手术,仅次于剖腹产。然而,对于最佳的子宫切除术,目前还没有达成共识。子宫切除术可以通过不同的技术实现,如胃切除术、阴道切除术和腹腔镜切除术。本研究的目的是探讨子宫良性病变的小切口子宫切除术在短期手术和术后表现方面是否是腹腔镜子宫切除术的可行选择。方法:将105例因子宫良性病变需要进行全子宫切除术的患者根据其治疗方法的偏好分为3类:a组(35例)采用传统缝合线的小切口子宫切除术。B组(35例)采用双极性血管封堵术(Ligasure)进行小切口子宫切除术。C组(35例)腹腔镜Ligasure子宫切除术。结果:A组(84.71±9.91分钟)、B组(55.31±7.81分钟)和C组(94.81±16.1分钟)的手术时间。与A组(17.41±1.91小时)和B组(16.51±1.761小时)相比,C组(12.31±2.51小时)恢复肠鸣音的持续时间。B组(99.11±30.81 ml)、A组(130.31±54.41 ml)和C组(136.61±6.61 ml)的失血量。住院时间最长的是A组(31.81±5.71小时),而B组(20.71±2.51小时)和C组(19.31±6.1小时)。疼痛评分最高的是A组(5.21±1.11)、B组(3.81±1.61)和C组(3.71±1.21)。术中或术后并发症的发生率没有显著差异。结论:小切口子宫切除术中使用ligasure双极性血管封堵器可减少手术时间和术中出血量,而住院时间与腹腔镜子宫切除术相当,术后疼痛评分低,住院时间有限。它可以是腹腔镜子宫切除术的一种可接受的替代方案,适用于没有腹腔镜经验或设施的地区。

Accurate estimation of gestational age is necessary to obtain materials for different tests as well as to interpret the results of these tests.Unfortunately sometimes calculation of EDD based on LMP becomes very difficult when (a) The menstrual cycle is irregular; (b) Patient fails to remember LMP or reports inaccurately (c) Pregnancy occurs during lactational amenorrhoea & (d) if patient have bleeding in early pregnancy. After 24 weeks the symphysio-fundal height in cm. approximates to the number of weeks up to 36 weeks of gestation. But a number of factors influence the measurement including multiple gestation, IUGR, diabetic pregnancy, maternal size, variation in fetal lie & engagement as well as inter & intra observer measurement variation.Ultrasonic measurement of fetal biometry (CRL, BPD, FL) are considered to be reliable when they are performed in first & early 2nd trimester (<24 weeks). In this study, we aimed to evaluate the accuracy of ultrasonographic fetal kidney length measurement as a new parameter for estimation of gestational age in late second and third trimester in correlation to other commenly used parameters as, BPD, FL, AC. This study was conducted on 122 pregnant women attending antenatal care clinics of Obstetrics and Gynecology department Soliman Fakeeh Hospital, KSA. All were in the late second and third trimester (between 24-40 weeks) of gestation. Cases included in the study were divided into four gestational age groups with four weeks interval. The length of the fetal kidney was measured. The mean gestational age was calculated on the bases of biparietal diameter (BPD).femur length (FL) and abdominal circumference (AC). The fetal kidney measurements were obtained by the same sonographer to avoid interobserver variation using (GE machine E8) and were compared with gestational age using statistical analysis No statistically significant differences were found between the right and the left renal measurements in cases in which the two kidneys were imaged In this study, during the second and third trimester the mean kidney length showed gradual rate of increase. the mean kidney length was found to be 30.52.1 mm at mean gestational age of 26weeks and became at the mean gestational age of34 weeks, 40.4103 mm(:(±1.98) and at mean gestational age of 38 week it measured44.41mm((±2.1). In addition, we found a positive correlation between kidney length and gestational age. We suggested regression Formula to calculate it. Conclusion: Throughout this study, we can conclude that Fetal kidney length could be used with accuracy in the late second and third trimester especially in women who are uncertain of date of LMP and are booked late for ANC.however its accuracy is decreased when we use it in late third trimester.Other ultrasonographic parameters used for estimation of the gestational age as BPD ,AC are less satisfactory ,when compared with femur length and kidney length.
准确估计胎龄对于获得不同测试的材料以及解释这些测试的结果是必要的。不幸的是,当(a)月经周期不规律时,有时基于LMP的EDD计算变得非常困难;(b) 患者不记得LMP或报告不准确(c)妊娠发生在哺乳期闭经期间&(d)如果患者在妊娠早期出血。24周后,以厘米为单位的基底联合高度接近妊娠36周的周数。但许多因素会影响测量,包括多胎妊娠、宫内节育器、糖尿病妊娠、母体大小、胎儿胎位和胎位的变化以及观察者之间和观察者内部的测量变化。当在妊娠早期和中期早期(<24周)进行胎儿生物测量时,胎儿生物测量(CRL、BPD、FL)被认为是可靠的。在这项研究中,我们旨在评估超声胎儿肾脏长度测量的准确性,该测量作为一个新的参数,与其他常用的参数(如BPD、FL、AC)相关,用于估计妊娠中期和晚期的胎龄。这项研究对在Soliman Fakeeh医院妇产科产前护理诊所就诊的122名孕妇进行,KSA。所有患者均处于妊娠中期和晚期(24-40周)。纳入研究的病例被分为四个孕龄组,间隔四周。测量胎儿肾脏的长度。根据双顶径(BPD)、股骨长度(FL)和腹围(AC)计算平均胎龄。胎儿肾脏测量值由同一位声谱仪使用(GE机器E8)获得,以避免观察者之间的差异,并使用统计分析将其与胎龄进行比较。在对两个肾脏进行成像的情况下,右肾和左肾测量值之间没有发现统计学上的显著差异。在本研究中,在妊娠中期和晚期,平均肾脏长度逐渐增加。平均胎龄26周时,平均肾长为30.52.1mm,平均胎龄34周时为40.4103mm(:(±1.98);平均胎龄38周时为44.41mm((±2.1)。此外,我们发现肾长与胎龄呈正相关。我们提出了回归公式来计算它。结论:在整个研究中,我们可以得出结论,胎儿肾脏长度在妊娠中期和晚期可以准确地使用,尤其是在不确定LMP日期和ANC预约较晚的女性中。然而,当我们在妊娠晚期使用它时,它的准确性会降低。与股骨长度和肾脏长度相比,用于估计胎龄(如BPD、AC)的其他超声参数不太令人满意。

The Role of The ?klotho Gene, Fgf21 and Fgfr1 in Cancerogenesis klotho基因、Fgf21和Fgfr1在肿瘤发生中的作用

Klotho was discovered in 1997 as an anti-aging gene that, when overexpressed, may extend the life span, but when it is disrupted, it may be a factor responsible for premature aging syndrome. The structure and the role of αKlotho and βKlotho genes from Klotho family in malignant tumors is described. The expression profile of the βKlotho gene is significantly different from the expression of the αKlotho gene. Analysis of Klotho expression in breast cancer, cervical cancer as well as endometrial cancer are discussed. The available data indicate the involvement of βKlotho in the neoplastic transformation of the endometrium. More advanced disease is related to negative expression of βKlotho gene. Fibroblast growth factors (FGFs) are a large family of proteins characterized by different functions in the cell development and metabolism. The FGF signaling is also associated with cancerogenesis. The relation between some FGF subfamilies and endometrial cancer clinical data is reported. The interaction between FGF subfamilies and the Klotho subfamily proteins acting as a co-receptor is stressed. Disorders in signaling of the FGF / FGFR pathway have been confirmed in gynecology. It can be assumed that increased expression of FGF21 might be a suppressor factor in endometrial cancer. The FGF21 factor, like the βKlotho protein, achieves its biological effect via the FGFR1 receptor. High expression of the FGFR1 gene inhibits further tumor growth. FGFR1 has the potential to perform both a suppressor and promoter role in the oncogenesis process.
Klotho于1997年被发现是一种抗衰老基因,当它过表达时,可能会延长寿命,但当它被破坏时,它可能是导致早衰综合征的一个因素。本文介绍了Klotho家族的αKlotho和βKlotho基因在恶性肿瘤中的结构和作用。βKlotho基因的表达谱与αKlotho的表达谱显著不同。本文分析了Klotho在乳腺癌症、癌症和癌症子宫内膜癌中的表达。现有数据表明βKlotho参与子宫内膜的肿瘤转化。更晚期的疾病与βKlotho基因的负表达有关。成纤维细胞生长因子(FGFs)是一大类蛋白质,在细胞发育和代谢中具有不同的功能。FGF信号传导也与癌症发生有关。报道了某些FGF亚家族与子宫内膜癌症临床资料的关系。FGF亚家族和作为共受体的Klotho亚家族蛋白之间的相互作用受到强调。FGF/FGFR通路的信号传导障碍已在妇科得到证实。可以推测FGF21表达的增加可能是癌症的抑制因子。FGF21因子与βKlotho蛋白一样,通过FGFR1受体实现其生物学作用。FGFR1基因的高表达抑制了肿瘤的进一步生长。FGFR1具有在肿瘤发生过程中发挥抑制和启动子作用的潜力。

The aim of this work is evaluation of different management options for patients with morbidly adherent placenta and its effect on pregnancy outcomes to find the best method of management to decrease morbidity and mortality. In this prospective study, there were 42 patients diagnosed as having morbidly adherent placenta previa and hospitalized between January 2019 to February 2020. Different management options performed to patients with morbidly adherent placenta previa were recorded, blood loss was estimated for each patient, operative procedures, maternal and fetal outcome was recorded. The results showed the following: Different methods were tried to preserve the uterus including bilateral uterine artery ligation in 13 (59%) cases, bilateral ovarian artery ligation in 3 (13.6%) cases, bilateral internal iliac artery ligation in 3 (13.6%) cases, intrauterine tamponade in 4 (18.1%) cases and hemostatic sutures in placental bed in 11(50%) cases, while B-lynch suture was not done, while procedures which were performed to control pelvic hemorrhage after hysterectomy included internal iliac artery ligation in 8 (27.5%) cases, pelvic packing in 5 (17.2%) cases and internal iliac balloon inflation to control hemorrhage in 1 (3.4%) case. The postoperative complications were DIC occurred in 2 patients (4.8%), ICU admission occurred in 5 cases (11.9%), two cases required reoperations, one patient (2.4%) had wound infection, Postpartum collapse occurred in 2 case (4.8%). Pulmonary embolism occurred in 1 case (2.4%), Median duration of hospital stay was 4 days (range: 2-25).

Intoduction This research assessed the determinants of the health services limited the supply of care related to the second pillar of the prevention of mother-child transmission of HIV (PMTCT) involving workers from the maternity units and the HIV active queues in the district hospitals and the Department of gynaecology, obstetrics and reproductive medicine (DGORM) of the National teaching hospital Souro Sanou (NTHSS) in the Region of Hauts Bassinsin the Region of Hauts Bassins, Burkina Faso. Materials and methods This was a cross-sectional study conducted from January 15 January to 30 July 2017. The study method used individual interview and the literature review (content analysis of national documents and activity reports on PMTCT). Results The main results included insufficient organization of services and low levels of the workers knowledge and activities related to the second pillar of PMTCT in the all health districts concerned. The second pillar of PMTCT has not been mentioned in any structure supervised. The definition of dual/double protection was only known by 9 (9.4%) participants. The knowledge of the strategies about the double protection was limited to a single strategy. The knowledge and activities on medically assisted procreation among people living with HIV were amost nil. The knowledge and practices on FP appropriate for People living wih HIV were poor. Conclusion For a successful PMTCT, it is important to implement its all four (04) pillars, taking into account the double/dual protection and the medically-assisted procreation.
这项研究评估了卫生服务的决定因素,限制了与预防母婴传播艾滋病毒(PMTCT)第二支柱相关的护理供应,涉及产科单位的工作人员,以及地区医院和妇科的艾滋病毒活跃队列,布基纳法索上巴辛斯地区国家教学医院Souro Sanou(NTHSS)的产科和生殖医学(DGORM)。材料和方法这是一项于2017年1月15日至7月30日进行的横断面研究。研究方法采用个人访谈和文献综述(对PMTCT国家文件和活动报告的内容分析)。结果主要结果包括所有相关卫生区的服务组织不足,工人对PMTCT第二支柱的知识和活动水平低。PMTCT的第二个支柱没有在任何监管结构中提及。只有9名(9.4%)参与者知道双重/双重保护的定义。对双重保护战略的了解仅限于单一战略。艾滋病毒感染者在医疗辅助生殖方面的知识和活动几乎为零。适合艾滋病毒携带者的计划生育知识和做法很差。结论对于一个成功的PMTCT,重要的是实施其全部四(04)支柱,同时考虑到双重/双重保护和医疗辅助生殖。

Back ground: World Health Organization (WHO) defines infertility as a disease of the reproductive system defined by the failure to achieve a clinical pregnancy after 12 months or more of regular unprotected sexual intercourse. Worldwide, 8 to 12 percent of couples experience fertility problems. Causes of infertility in women were as follows: menstrual disorders (disorders of cycle length and flow) 62.6%, diseases (obesity, thyroid diseases, diabetes) 58.7%, impaired ovulation (hormonal disorders, oligoovulation and anovulation) 50.3%, uterine causes 16.7%, tubal factor 15.4%, and cervical causes 7.9%. In the male factor fertility there was semen abnormalities (44.6%), genetic factors (29.8%), anti-spermatogenesis agents (11%), and vascular disorders (17.2%). Aim of the Study: The purpose of this study is to evaluate the effect of sildenafil in endometrial ripening with induction of ovulation by clomiphene citrate in polycystic ovarian syndrome. Patients and methods: It is a randomized controlled trial on 65 infertile women with polycystic ovarian syndrome; patients were randomly divided into two equal groups. In control group, 31 patients were given oral sildenafil, one tablet every 12 hrs. From 2nd day of the cycle till 12th day and clomiphene citrate, one tablet every 12 hours, for 5 days from 3rd day of the menstrual cycle. In study group, 34 patients were given oral placebo, one tablet every 12 hrs. From 2nd day of the cycle till 12th day and clomiphene citrate, one tablet every 12 hours, for 5 days from 3rd day of the menstrual cycle. A transvaginal ultrasound was performed to evaluated the endometrial thickness before and after treatment, the follicularometeric was measured on day 11 and day13. Uterine artery Doppler was then measured. Qualitative serum B-hCG level was checked 14 days after ovulation to assess clinical pregnancy rate. Design: Prospective, Double blinded randomized controlled trial. Setting: Obstetrics & Gynecology outpatient clinic, Ain Shams University Hospital. Study duration: 3 months. Results: The present study was a double-blind, randomized, controlled study that was conducted on 65 women with PCOS who underwent induction of ovulation by Clomiphene citrate in outpatient clinic of Ain Shams University hospital. Conclusion: Our systematic review and meta-analysis showed that follicular supplementation of sildenafil citrate (oral or vaginal), alone or adjuvant therapy can be used for improving the EM and clinical pregnancy rate in women undergoing assisted reproduction. However, given the methodological limitations the current evidence does not support its use in clinical practice yet. Future high-quality RCT with large sample size to evaluate the sildenafil citrate effect in women undergoing assisted reproduction are needed. Future RCTs should focus on type of processing, stage of embryo, embryo quality, dosage, time of administration, type of control group, in order to identify the groups of patients who would benefit t
背景:世界卫生组织(世卫组织)将不孕症定义为一种生殖系统疾病,其特征是定期无保护性交12个月或更长时间后仍未实现临床妊娠。在世界范围内,8%到12%的夫妇都有生育问题。妇女不孕的原因如下:月经紊乱(周期长度和流量紊乱)62.6%,疾病(肥胖、甲状腺疾病、糖尿病)58.7%,排卵障碍(激素紊乱、排卵少和无排卵)50.3%,子宫原因16.7%,输卵管因素15.4%,宫颈原因7.9%。在男性因素生育中,精液异常(44.6%)、遗传因素(29.8%)、抗生精剂(11%)和血管疾病(17.2%)。研究目的:本研究的目的是评价西地那非对多囊卵巢综合征患者子宫内膜成熟和枸橼酸克罗米芬诱导排卵的影响。患者和方法:对65例多囊卵巢综合征不孕妇女进行随机对照试验;患者被随机分为两组。对照组31例患者口服西地那非,每12 h 1片。从月经周期第2天起至第12天,服用枸橼酸克罗米芬,每12小时一片,从月经周期第3天起连续服用5天。研究组34例患者口服安慰剂,每12小时1片。从月经周期第2天起至第12天,服用枸橼酸克罗米芬,每12小时一片,从月经周期第3天起连续服用5天。治疗前后行阴道超声检查子宫内膜厚度,第11天、第13天测量卵泡计。然后测量子宫动脉多普勒。排卵后14天检测定性血清B-hCG水平,评价临床妊娠率。设计:前瞻性、双盲随机对照试验。单位:艾因沙姆斯大学附属医院妇产科门诊。学习时间:3个月。结果:本研究是一项双盲、随机、对照研究,在艾因沙姆斯大学医院门诊接受枸橼酸克罗米芬诱导排卵的PCOS女性65例。结论:我们的系统回顾和荟萃分析显示,卵泡补充枸橼酸西地那非(口服或阴道)、单独或辅助治疗可提高辅助生殖妇女的EM和临床妊娠率。然而,由于方法学的局限性,目前的证据尚不支持其在临床实践中的应用。未来需要高质量的大样样量的随机对照试验来评估枸橼酸西地那非对辅助生殖妇女的影响。未来的随机对照试验应关注处理方式、胚胎阶段、胚胎质量、剂量、给药时间、对照组类型,以确定从该干预中获益最多的患者群体,以及柠檬酸西地那非最合适的剂量、时间和类型,从而产生最积极的效果,减少可能的副作用。
