Objective

Shenmai injection (SMI) is an established treatment for cardiac diseases, and we performed to evaluate the efficacy of SMI combined with chemotherapy drugs for the treatment of chemotherapy-induced cardiotoxicity.

Methods

The primary outcome was abnormal electrocardiogram (ECG), left ventricular ejection fraction (LVEF) and E/A. The secondary outcomes included myocardial injury biomarkers (creatine kinase [CK], creatine kinase MB [CK-MB], and cardiac troponin I [cTnI]) and lipid peroxide markers (superoxide dismutase [SOD], glutathione [GSH], and malondialdehyde [MAD]).

Results

Studies indicated that SMI combined with chemotherapy drugs has advantages over chemotherapy drugs alone in reducing the incidence of abnormal ECG (ST-T: RR = 0.613, 95% CI [0.437, 0.862], P = 0.005; extrasystole: RR = 0.527, 95% CI [0.349, 0.798], P = 0.002). Myocardial injury biomarkers in the experimental group were lower than those in the control group (CK: SMD = –2.614, 95% CI [–3.156, –2.071], P = 0.000; CK-MB: SMD = –6.882, 95% CI [–8.982, –4.782], P = 0.000; cTnI: SMD = –3.610, 95% CI [–4.949, –2.271], P = 0.000). Ultrasonic cardiogram analysis showed that the experimental group had a higher LVEF and E/A than the control group (LVEF: SMD = 1.572, 95% CI [1.176, 1.969], P = 0.000; E/A: SMD = 0.280, 95% CI [0.153, 0.407], P = 0.000). Lipid peroxide meta-analysis showed that the experimental group had higher SOD and GSH levels (SOD: weighted mean difference (WMD) = 39.783, 95% CI (32.524, 47.042), P = 0.000; GSH: WMD = 32.960, 95% CI [26.055, 39.865], P = 0.000), and lower malondialdehyde (MDA) (WMD = –4.962, 95% CI [–6.041, –3.883], P = 0.000).

Conclusion

SMI is effective in reducing cardiac injury and the incidence of cardiotoxicity.

Introduction

Studies on the antimutagenic and anti-neoplastic effect of dietary ingredients can be useful in developing nutraceuticals for preventing neoplastic induction. In the current study the query whether food rich in antimutagenic potential equally suppress the neoplastic induction, was addressed, with potential mechanism of action.

Methods

The antimutagenic activity was evaluated using the TK6 gene mutation assay, assessing the reduction in ethyl methanesulfonate (EMS)-induced mutation in presence of vegetable extracts. The anti-⁠neoplastic activity was assessed using the C3H/⁠10T1/⁠2 cell transformation assay, quantifying the inhibition of anchorage-independent growth and type III foci formation. The prominent compounds in the vegetable extract were characterised using gas chromatography-⁠mass spectrometry (GC-⁠MS), and their interactions with DNA were predicted using molecular docking.

Results

Among the vegetable extracts, garlic exhibited the most potent antimutagenic and anti-neoplastic effects, followed by spinach and beans. Garlic extract exhibited significantly high antimutagenic potential (59 ± 3%), and anti-neoplastic activity in the terms of inhibition of anchorage independence (65 ± 3%) and inhibition of type III foci formation (90 ± 5%). GC-MS analysis of garlic extract identified abundant organosulphur compounds, terpenes, and terpenoids. Molecular docking studies suggested that these compounds bind to the DNA minor groove with binding energies ranging from −⁠4.3 to −⁠7.21 kcal mol^-⁠1.

Discussion

The antimutagenic and antineoplastic activities showed a positive correlation (r = 0.92–0.93), where garlic extract showed the highest potential. The DNA binding properties of the prominent compounds in garlic extract suggests a potential mechanism of action involving interference with carcinogen activity and subsequent prevention of gene dysregulation.

Introduction

Paediatric community-acquired pneumonia (CAP) is a prevailing respiratory infection that impacts children in non-medical settings, giving rise to substantial morbidity and mortality, especially in less developed areas. The current study was aimed at finding a holistic approach for improving the management and treatment of paediatric CAP. For that purpose, a comparative interventional study was conducted to investigate the effectiveness of chest physiotherapy (CPT) combining with Cinnamon varum and Syzygium aromaticum steam therapy in paediatric CAP.

Methods

A total of 60 paediatric patient hospitalised with CAP were assessed. The study included both male and female participants aged between three and 14 years. The study was conducted at Children Hospital and Institute of Child Health in Faisalabad, Pakistan. The subjects were divided into three equal groups: group 1 received CPT, group 2 underwent CPT accompanied with nebulization, and group 3 received CPT along with steam therapy using C. varum and S. aromaticum. Each participant received the assigned therapy twice a day for seven consecutive days. The study was approved and registered by Ethics Review Committee, Government College University, Faisalabad, Pakistan (Reference number GCUF/ERC/214).

Results

Among the three groups studied, those who received the combined therapy exhibited improved outcome by improving the complete blood count (CBC), spirometer index, arterial blood gases (ABGs) and Systolic blood pressure, Multilobar infiltrates, Albumin, Respiratory rate, Tachycardia, Confusion, Oxygen and pH severity score for pneumonia.

Conclusions

The antimicrobial, anti-inflammatory and mucolytic properties of cinnamon and clove, along with the positive effects of CPT, resulted in reduced lung inflammation, enhanced respiratory performance, and improved vital signs.

Introduction

Human papillomavirus (HPV) is a major cause of cervical cancer, particularly types 16 and 18, which are responsible for 70% of cases. The current study’s main aim is to evaluate the impact of using herbal medicine extract for the management of HPV-related cervical and gynaecological pathogenesis.

Methods

A systematic literature was accomplished and 2007 patients with HPV-related diseases were recruited to the current studies; 1 089 of them were treated with herbal extracted products, and 918 were control groups. The inclusion criteria of the current study recruited only randomised clinical trials with a comparison-based design.

Results

Using herbal extracts for the treatment of HPV-related pathogenesis showed a significant improvement in short- and long-term using several plant-based preparations. Improved parameters were the rate of HPV clearance (P < 0.001), rate of cervical intraepithelial neoplasia (P < 0.001), and adverse events (P > 0.05). In contrast to the significant difference between the intervention group and control regarding efficacy-related parameters, there were no significant differences regarding adverse events occurrence rate. The heterogeneity of different model levels was assessed by I² and ranged from 0% to 86.6%.

Conclusions

Using herbal medicine for the management of HPV-related cervical pathogenesis showed a beneficial impact regarding the clearance rate of high-risk HPV and a higher rate of cervical intraepithelial neoplasia regression. In addition, herbal medicines showed high safety rates compared to control.

Introduction

Network pharmacology approaches were applied to reveal the mechanism of Wenhua Decoction in non–small cell lung cancer (NSCLC) treatment.

Methods

Effective chemical constituents and targets of Wenhua Decoction were collected by database, and differentially expressed genes of NSCLC were screened. Restart random walk analysis for protein-protein interaction network was conducted using the intersected genes of differentially expressed genes and target genes in NSCLC as seeds. The top 50 genes in affinity coefficient were used to construct the drug-active constituent-gene interaction network. Molecular docking and molecular dynamic analyses were conducted for core targets and corresponding active constituents in the network. Quercetin content was determined by HPLC. Quantitative real time polymerase chain reaction (qRT-PCR) was performed to assess CDK1 expression in A549 cells. The effects of Wenhua Decoction on the cell cycle were evaluated in sh-CDK1 cells. Cellular thermal shift assay was utilised to examine the binding status between CDK1 and its target quercetin.

Results

The drug-active constituent-gene interaction network demonstrated that CDK1 was at the core of the network. Quercetin could bind to CDK1 stably while causing no significant changes in protein conformation. Wenhua Decoction treatment significantly reduced CDK1 expression and blocked transition of cancer cells from the G1 to the S phase. The quercetin content was 16.0 μg/g. Furthermore, cellular thermal shift assay experiment showed a high binding affinity between CDK1 and quercetin present in the Wenhua Decoction.

IF 2.2 4区医学 Q2 INTEGRATIVE & COMPLEMENTARY MEDICINE

Journal of Herbal Medicine

Pub Date : 2024-09-01 DOI: 10.1016/j.hermed.2024.100928

Introduction

The prevalence of oral diseases has been rising, presenting a significant challenge exacerbated by the increasing resistance of bacteria due to the inappropriate use of antibiotics. Given the typical financial challenges encountered in developing nations, there is an urgent requirement for alternative approaches and materials to address and manage these diseases. This study aims to investigate the chemical composition and antimicrobial properties of Psidium guajava leaf essential oil (PGL-EO) against specific oral bacterial species.

Methods

The extraction of PGL-EO was conducted using a Clevenger apparatus, and the chemical composition of PGL-EO was determined using gas chromatography-mass spectrometry (GC-MS) analysis. Various microbial strains from the American Type Culture Collection (ATCC) and clinically obtained oral strains were selected, and the antibacterial activity was assessed using the microdilution broth technique.

Results

The GC-MS analysis indicated the existence of 28 chemicals in PGL-EO, representing 97.76% of the total oil composition. The primary constituents found in this material consisted of l-limonene (31.70%), caryophyllene (27.31%), and caryophyllene oxide (6.90%). In addition, the major phytochemical class was sesquiterpene hydrocarbons (42.35%), followed by monoterpene hydrocarbons (32.30%) and oxygenated sesquiterpenoids (21.51%). PGL-EO exhibited remarkable antimicrobial efficacy against Streptococcus mutans, Streptococcus mitis, Streptococcus sanguinis, Enterococcus faecalis, Lactobacillus acidophilus, and Candida albicans..

Conclusions

The findings of this study strongly suggest that PGL-EO holds potential as an effective anti-plaque and anticary agent. Furthermore, the results obtained in this study consider PGL-EO a promising anticandidal agent in that it can contribute to treating and preventing oral diseases.

South African medicinal plants used for health conditions affecting males: an ethnobotanical review 南非用于治疗男性健康问题的药用植物：人种植物学综述

IF 2.2 4区医学 Q2 INTEGRATIVE & COMPLEMENTARY MEDICINE

Journal of Herbal Medicine

Pub Date : 2024-09-01 DOI: 10.1016/j.hermed.2024.100931

Introduction

Health issues affecting males remain a public health challenge due to the limited treatments and male health-seeking behaviour. In South Africa, local communities have relied on plant-based therapies to address health issues including those affecting males. This review explored the ethnobotanical and indigenous knowledge of plants used for managing male urogenital and sexual-reproductive conditions in South Africa, to establish the existing status and identify gaps for further research.

Methods

Following a systematic search, 51 eligible studies were extracted from electronic databases.

Results

A total of 337 plants belonging to 83 families were collated across seven provinces in South Africa. Fabaceae (37) and Asteraceae (37) were the most represented plant families. Hypoxis hemerocallidea Fisch., C.A.Mey. & Avé-Lall. (18 citations), and Entada elephantina (Burch.) S.A.O’Donnell & G.P.Lewis (synonym: Elephantorrhiza elephantina (Burch.) Skeels) (12 citations) were the commonly used plants. Roots (33.4%) and leaves (17%) were the most commonly used plant parts. Decoction (44%) and oral-based (53%) were the dominant preparation and administration method, respectively. The two major health conditions had 18 sub-categories as derived from the eligible studies. Particularly, aphrodisiac and erectile dysfunction were the most encountered conditions and were managed with 133 plants. Provinces such as the Northern Cape and North West had limited studies on plants used for male healthcare needs.

Conclusion

We highlighted the importance of plants in meeting the primary healthcare needs of males. This suggests the need to promote additional research into the cultural, therapeutic, and dynamic trends in the use of plants for meeting the healthcare needs of males, especially in rural areas.

导言：由于治疗方法有限和男性寻求健康的行为，影响男性的健康问题仍然是一项公共卫生挑战。在南非，当地社区依靠植物疗法来解决健康问题，包括影响男性的健康问题。本综述探讨了南非用于治疗男性泌尿生殖和性生殖疾病的植物的人种植物学和本土知识，以确定现有状况并找出有待进一步研究的差距。其中最多的植物科是豆科（37 种）和菊科（37 种）。Hypoxis hemerocallidea Fisch.(18次引用）和 Entada elephantina (Burch.) S.A.O'Donnell & G.P.Lewis （异名：Elephantorrhiza elephantina (Burch.)
