Pneumocystis pneumonia (PCP) is a pulmonary disease that occurs frequently in immunocompromised and acquired human immunodeficiency virus infected patients.Severe patients can be life-threatening.Trimethoprim-sulfamethoxazole is the first choice for first-line treatment, but it has potential drug resistance.Most mild patients have good prognosis after using compound sulfamethoxazole and active treatment of primary diseases.However, for severe patients, due to lack of specific diagnostic methods in the early stage, the course of disease progresses rapidly, and glucocorticoid therapy can be combined to reduce the mortality of PCP.This article reviews the progress of treatment of PCP.

Objective To explore the significance of immunohistochemical expression of Ryanodine receptor 2 (RYR2), FK506-binding protein 12.6 (FKBP12.6) and Calcium/ calmodulin dependent protein kinaseⅡ (CaMK-Ⅱ) in lung tissues from patients with chronic obstructive pulmonary disease (COPD). Methods A retrospective analysis from November 2012 to April 2017 in People′s Hospital of Ningxia Hui Autonomous Regin, lung tissue of 30 patients after lung cancer surgery, according to the results of pulmonary function test and Cardio-Uhrasonography, the patients were divided into three groups: COPD with pulmonary hypertension (PH)(group A) and COPD group (group B), non-COPD, non-PH patients with pulmonary tumor as the negative control group (group C). Take lung tissue about 5 cm from the cancerous area was removed after surgery.The Circum-ferential area of pulmonary valve of the three groups has been observed.To observe RYR2, FKBP12.6 and CaMK-Ⅱby immunohistochemical method respectively, then make correlation analysis. Results (1)Compared with group C, wall area% (WA%), pulmonary artery systolic pressure (PASP) were higher in group A and group B (F=24.115, 9.421, both P<0.05), and WA%, PASP were higher in group A than group B. (2)Compared with group C, the immunohistochemical expressions of RYR2, FKBP12.6 and CaMK-Ⅱ in group A and group B were all increased (F=9.219, 6.143, 11.337, all P<0.05), and the immunohistochemical expressions of RYR2, FKBP12.6 and CaMK-Ⅱ in group A was higher than group B. (3)Correlation analysis indicated that the immunohistochemical expressions of RYR2 in group A and B was positively correlated with WA% (r=0.547, 0.771, both P<0.01), while the immunohistochemical expressions of RYR2 in group A was positively correlated with PASP (r=0.773, P<0.01). Histochemical expressions of FKBP12.6 in group A were positively correlated with WA% (r=0.796, 0.810, both P<0.01), and the immunohistochemical expressions of FKBP12.6 in group A was positively correlated with PASP (r=0.729, P<0.01). The immunohistochemical expressions of CaMK-Ⅱ in group A and B were positively correlated with WA% (r=0.879, 0.504, both P<0.01), and the immunohistochemical expressions of CaMK-Ⅱ in group A was positively correlated with PASP (r=0.748, P<0.01). Conclusions FKBP12.6 and CaMK-Ⅱ may play a role in COPD-related pulmonary artery proliferation.

Objective To analyze the expression of Foxp3-mRNA and the regulation of Th1/Th2 immune response in patients with chronic obstructive pulmonary disease (COPD), and to provide a theoretical basis for the monitoring of immune status and its related mechanisms in patients with COPD. Methods A group sampling method was used to select 95 cases of patients with COPD who received a follow-up treatment in a third-grade hospital in the same hospital and 85 controls were conducted at the same time, from March 2016 to December 2017.The Foxp3-mRNA fragment was amplified by PCR and the expression of Foxp3-mRNA in serum was detected by Western blot.The expression of Th1/Th2 immune response system expression assay (including IFN-γ, IL-2, IL-4, IL-10), the obtained data were entered into SPSS 16.0 for statistical analysis. Results The level of IFN-γ, IL-2, IL-4, IL-10 in COPD group were higher than those of in the control group and there were statistical differences(t=7.282, 5.996, 7.380, 4.835, all P<0.05). In the case group, patients of different ages in IFN-γ, IL-2, IL-4, IL-10, were statistically different (t=22.237, 16.943, 45.386, 31.831, all P<0.05). In the case group, patients of different disease durations in IFN-γ, IL-2, IL-4, IL-10 were statistically different (F=33.226, 30.096, 29.353, 34.300, all P<0.05). In the case group, clear bands were seen at about 592 bp (group 1 to group 5), while the control group (group 6) and the DNA marker group (group 7) had no bands.The levels of IL-2, IL-4 and IL-10 were positively correlated and the correlation coefficients were statistically significant (r=0.614, 0.493, 0.529, 0.501, all P<0.05). Conclusions The theoretical basis for the specific expression of Foxp3-mRNA in patients with COPD is established.There is a statistically positive correlation between the expression of Foxp3-mRNA and the characteristics of Th1/Th2 immune response, but considering the epidemic of COPD in China.Characteristics, this conclusion also needs to be combined with the environmental epidemiological factors of patients with COPD to further verify the relationship between Foxp3-mRNA expression characteristics and Th1/Th2 immune response characteristics at the mechanism level.

Chronic obstructive pulmonary disease (COPD) is a common inflammatory disease of the respiratory tract.It is one of the diseases with high morbidity and mortality in the world.Acute exacerbation of COPD(AECOPD) is an important event in the process of COPD, which often leads to the decline of patients′ quality of life and the increase of mortality.Respiratory virus infection is closely related to AECOPD.Viral infection in patients with AECOPD is characterized by diversity, seasonality and locality.Respiratory virus infection can aggravate COPD by activating inflammatory mediators and participating in immune response.The effects and mechanisms of various viral infections on AECOPD may be different and require further study. Key words: Pulmonary disease, chronic obstructive; Viruses
慢性阻塞性肺病(COPD)是一种常见的呼吸道炎症性疾病。它是世界上发病率和死亡率最高的疾病之一。慢性阻塞性肺病急性加重(Acute exacerbation of COPD, AECOPD)是慢性阻塞性肺病病程中的重要事件，常导致患者生活质量下降，死亡率升高。呼吸道病毒感染与AECOPD密切相关。AECOPD患者的病毒感染具有多样性、季节性和地域性的特点。呼吸道病毒感染可通过激活炎症介质和参与免疫应答而加重COPD。各种病毒感染对AECOPD的作用和机制可能不同，需要进一步研究。关键词:肺部疾病;慢性阻塞性肺疾病;病毒
