OBJECTIVE To explore the correlation between Pneumocystic carinii pneumonia(PCP) in HIV/AIDS and CD4+T-lymphocyte level.METHODS Totally 300 cases from more than 10 000 HIV/AIDS patients who were taken chest X-ray were sampled randomly.According to count of CD4+T-lymphocyte number,300 cases were divided into 2 groups: the count of CD4+T-lymphocyte number over than 200/mm3 was group A,while the other was group B.Analysis and comparison of lung complications in HIV/AIDS and follow-up survey of PCP curative effect in these 2 groups were done.RESULTS PTB,PCP,bacterial pneumonia Kaposi sarcoma(KS) and other lung ailmentd were the most common lung complications in HIV/AIDS.There were more lung complications and worse effect of PCP therapy in group B.There was significantly difference in group A and group B(P

Objective:To explore the mechanism of Xijiao Dihuang Ddecoction (XJDHT) against sepsis-induced liver injury based on transcriptomics.Methods:Sixty C57BL/6 mice were randomly (random number) divided into the sepsis group, sepsis treatment with XJDHT and control group, with 20 mice in each group. The sepsis mouse model was established by intraperitoneal (i.p.) injection of lipopolysaccharide (LPS). The control group was intraperitoneally injected with the same amount of normal saline. The sepsis treatment with XJDHT group was injected with XJDHT (crude drug 187.5 mg) twice a day 2 days before modeling. After modeling, gastric feeding was continued twice a day, while the control group and sepsis group were gavaged with the same amount of normal saline. At 72 h after LPS intervention, 9 mice in each group were randomly selected. After anesthesia, part of the liver were taken for small RNA and RNA sequencing and analysis, and part of the liver were taken for pathological examination.Results:XJDHT could improve the histopathological changes of liver in septic mice, and alleviate some abnormally expressed microRNAs (mmu-mir-292a-5p, mmu-mir-871-3p, mmu-mir-653-5p, mmu-mir-293-5p, mmu-mir-155-3p, mmu-mir-346-5p, mmu-mir-187-5p, mmu-mir-3090-3p) and their target genes.Conclusions:XJDHT can reduce the liver histopathological changes in septic mice, and its mechanism may be related to XJDHT regulating the expression of important key genes of liver of sepsis like mmu-mir-187-5p and its target genes such as ADAM8, irak3 and PFKFB3

Objective To investigate the effect of modified controllable lateral prone position in thoracoscope resection of esophageal carcinoma. Methods From December 2011 to December 2013, 200 cases of esophageal cancer patients treated by thoracoscope resection were randomly divided into observation group and control group, with 100 cases each. Observation group adopted the modified controllable lateral prone position, and the control group was given the traditional lateral position. The different postures of the skin pressure situation, operation field exposure, anesthesia cost and doctors′ satisfaction and so on were compared between two groups. Results The incidence of skin complications, operation time, anesthesia cost in the observation group were 4. 0%, (78 ± 20) min and (1 812 ± 490) RMB, respectively, which were significantly lower than those in the control group (χ2/t=4. 348,-13. 929,-3. 683, respectively;P<0. 05). The doctor satisfaction of the observation group was 99% which was significantly higher than 93% of the control group (χ2 =4. 688, P<0. 05). Conclusions The modified controllable lateral prone position can fully expose the operation field during thoracoscope resection of esophageal carcinoma, reduce the operation time, make sure patients safety and comfort, reduce the skin complications, decrease the cost of anesthesia, so it is worthy of clinical popularization and application.

Objective To study the effect of age-related white matter changes (ARWMC) on first symptomatic ischemic stroke events in the oldsters. Methods For the prospective study, a total of 368 eligible oldsters were enrolled in the study from January 2010 to August 2012. The degrees of ARWMC were assessed by ARWMC scale;according to the scores, they were divided into non ARWMC group, mild-moderate ARWMC group and severe ARWMC group. The patients were followed up once every 3 months. The clinical endpoint events and time (first symptomatic ischemic stroke, myocardial infarction and all-cause death) were recorded. Analyses of variance and Chi-square test were used to compare the differences of clinical data among the 3 groups. COX regression was used to assess the risk differences of first symptomatic ischemic stroke in the oldsters of three groups. Results After an average of follow-up for 48.7 months, 50 participants (13.6％) had first symptomatic ischemic stroke;25 (25.8％) were categorized as the severe ARWMC group, 22 (10.9％) were as the mild-medium group, and 3 (4.4％) were as the non ARWMC group. Among the three groups, the differences in age, history of hypertension, systolic blood pressure, incidence of clinical endpoint events and first symptomatic ischemic stroke, and follow-up time of endpoint events were statistically significant (P<0.05); patients from the severe ARWMC group were the oldest, and had the longest history of hypertension, the highest systolic blood pressure, the highest incidence of clinical end events and first symptomatic ischemic stroke, and the shortest follow-up period for clinical end events. COX regression analysis showed that the risk of first symptomatic ischemic stroke in the severe ARWMC group was about 8 times higher than that in the non ARWMC group (hazard ratio=9.012, 95％CI: 2.310-35.154, P=0.002). Conclusion In oldsters, severe ARWMC often accompany hypertension history and poor blood pressure controll, and it is an independent and serious risk factor for long-term first symptomatic ischemic stroke.
