Abstract: Objective　To analyze the survival status of HIV/AIDS patients aged above 50 years receiving antiviral therapy (ART) in Shanxi Province from 2011 to 2019, and to provide evidence for further improvement of antiviral therapy. Methods　Basic information and follow-up information of HIV/AIDS patients aged above 50 years who first received HIV/AIDS antiviral therapy in Shanxi Province from 2011 to 2019 were collected. Excel database was established and SPSS23.0 software was used for analysis. Retrospective cohort study was conducted. Cox proportional risk regression model was used to analyze the factors influencing survival time. Results　A total of 1 183 subjects were included, of which 172 died, including 84(48.84%) from other causes, 74(43.02%) AIDS-related death and 14 (8.14%) from accidents, suicides and undetermined deaths. Setting AIDS-related deaths as an outcome event, life table analysis showed that the cumulative survival rates at 1, 3, 5, 7 and 9 years after receiving ART were 96.61%, 93.59%, 90.35%, 87.57% and 83.44%, respectively. Multivariate Cox proportional risk model analysis showed that the risk of death in patients aged 60-<70 years group and over 70 age group was 2.53 times (95%CI: 1.51-4.23) and 3.59 times (95%CI: 1.74-7.40) for patients aged the 50-<60 group , respectively. The risk of death in patients with baseline CD4+T lymphocyte (CD4) counts of ≥200/mm3, 50-<200 /mm3 was 0.22 times (95%CI: 0.12-0.41) and 0.37 times (95%CI: 0.21-0.67) for patients with CD4+T lymphocyte counts of <50/mm3. The risk of death in patients with opportunistic infections at baseline was 1.99 times (95%CI: 1.16-3.39) for patients without baseline opportunistic infections. Conclusions　The survival rate of HIV/AIDS patients aged above 50 who received antiviral therapy (ART) in Shanxi Province from 2011 to 2019 was relatively high. To further improve the quality of antiviral treatment in our province, the strategy of "early detection and early treatment" should be continued and improved in the future, and information collection of specific causes of non-AIDS-related deaths among this population should be further strengthened.

Kawasaki disease is the main cause of acquired heart disease in children. The cardiovascular sequelae of Kawasaki disease, such as coronary artery lesion and giant coronary aneurysm, have a great impact on children's physical and mental health. The Japanese Circulatory Society and the Japanese Society of Cardiac Surgery jointly released the JCS/JSCS 2020 guideline on diagnosis and management of cardiovascular sequelae in Kawasaki disease in July, 2020, which systematically introduces the advances in the diagnosis and management of cardiovascular sequelae of Kawasaki disease. The article gives an interpretation in the severity evaluation of Kawasaki disease and diagnosis, treatment and long-term management of cardiovascular sequelae in the guideline.

Objective: To investigate the safety and efficacy of pulmonary vein deployment technique for percutaneous closure of atrial septal defects (ASD) solely under echocardiography guidance. Methods: A total of 38 ASD patients received pulmonary vein deployment in our hospital from 2012-10 to 2016-09 since the conventional method could not deliver the occluder to correct place. The patients were with the mean age at (16.0±15.6) years, body weight at (37.2±22.9) kg and ASD diameter at (17.1±4.2) mm. Operative effect was assessed by echocardiography. Follow-up study was conducted at 1, 3, 6, 12 months post-operation and at each year thereafter. Results: 37 patients were successfully finished pulmonary vein deployment for percutaneous closure of ASD solely under echocardiography guidance. One patient was successfully treated by a controlled steerable sheath. The mean operative time was (25.2±5.1) min and mean diameter of ASD occluder was (22.9±5.6) mm. 2 patients had trivial residual shunt at the early post-operative stage. No peripheral vascular injury, pulmonary vein and cardiac perforation occurred. All 38 patients were recovered and discharged. The average in-hospital time was (2.9±0.7) days. The patients were followed-up for (23.9±15.4) months, without complications of residual shunt, pericardial effusion, aortic regurgitation and pulmonary vein stenosis. Conclusion: Pulmonary vein deployment technique for percutaneous closure of ASD solely under echocardiography guidance was safe and effective; it can avoid radiation damage and provided a simple and practical method for ASD patients who failed to conventional method under echocardiography guidance.

OBJECTIVETo observe the effect of Schistosoma japonicum cysteine protease inhibitor (rSjCystatin) for treatment of lipopolysaccharide (LPS)-induced sepsis in mice.

METHODSAfter a week of adaptive feeding, 54 BALB/c mice were randomly divided into normal control group (group A), sepsis group (group B), and rSjCystatin intervention group (group C). The mice in group A received an intraperitoneal injection of PBS (100 µL), and those in groups B and C were injected with PBS (100 µL) containing LPS (10 mg/kg); the mice in group C were also intraperitoneally injected with 25 µg sjCystatin in 100 µL PBS 30 min after LPS injection. From each group, 10 mice were randomly selected 24 h after PBS or LPS injection for detecting serum levels of TNF-α, IL-6, and IL-10 using ELISA and the levels of ALT, AST, BUN, and Cr using automatic biochemical analyzer; the pathological changes in the liver, lung and kidney were observed with HE staining. The remaining 8 mice in each group were used for observing the changes in the general condition and the 72-h survival.

RESULTSThe 72-h survival rates of the mice was 100% in group A, 0 in group B, and 36% in group C, showing a significant difference among the 3 groups (P<0.05). Compared with those in group A, the mice in group B exhibited obvious liver, lung, and renal pathologies with increased levels of ALT, AST, BUN, Cr, IL-6, and TNF-α (P<0.05). Treatment with sjCystatin significantly lessened LPS-induced organ pathologies, lowered the levels of liver and renal functional indexes and the pro-inflammatory cytokines, and increased the serum level of IL-10 in the mice (P<0.05).

CONCLUSIONSjCystatin can produce a significant therapeutic effect on sepsis induced by LPS in mice.

The identification and use of molecular biomarkers have greatly improved the diagnosis and treatment of malignant tumors. However, a much deeper understanding of oncogenic proteins is needed for the benefit to cancer patients. The lipid raft marker proteins, flotillin-1 and flotillin-2, were first found in goldfish retinal ganglion cells during axon regeneration. They have since been found in a variety of cells, mainly on the inner surface of cell membranes, and not only act as a skeleton to provide a platform for protein-protein interactions, but also are involved in signal transduction, nerve regeneration, endocytosis, and lymphocyte activation. Previous studies have shown that flotillins are closely associated with tumor development, invasion, and metastasis. In this article, we review the functions of flotillins in relevant cell processes, their underlying mechanisms of action in a variety of tumors, and their potential applications to tumor molecular diagnosis and targeted therapy.

OBJECTIVEVitamin D receptor (VDR) has been proposed as a candidate gene for susceptibility to Parkinson's disease (PD). This study was set to assess the association between VDR gene Apa I and Taq I polymorphisms and PD in a Chinese Han population.

METHODSTwo hundred and eighty five sporadic PD patients and 285 healthy controls were genotyped for the Apa I and Taq I polymorphisms in VDR gene using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method.

RESULTSNo significant difference was detected in genotype or allele distribution of both Apa I and Taq I polymorphisms between PD patients and controls (P U+003E 0.05). No TT genotype for Taq I was found in the studied population. For Taq I, the distribution of genotype was significantly different between male PD patients and controls (U+03C7 2=4.187, P=0.032, OR=2.149, 95%CI: 1.011-4.567), and the frequency of T allele was significantly higher in male PD patients than male controls (U+03C7 2=3.867, P=0.036, OR=2.064, 95%CI: 0.989-4.307).

CONCLUSIONVDR gene Apa I polymorphisms are not associated with sporadic Parkinson's disease, but Taq I may be a risk factor for male PD.

BACKGROUNDAcute exacerbation of chronic obstructive pulmonary disease (COPD) is always associated with a high incidence and mortality. Because of the presence of some concomitant risk factors such as immobilization, bronchial superinfection, patients who are admitted for acute exacerbations of COPD are generally considered to be at moderate risk for the development of venous thromboembolism. In this study, we investigated the prevalence and the clinical manifestations of deep venous thrombosis (DVT) in patients with acute exacerbation of COPD.

METHODSFrom March 2007 to March 2009, 520 consecutive patients were included in this study. On admission, color Doppler ultrasound of lower extremities in all cases was performed for diagnosing DVT. Patients with DVT were compared with those without DVT from such aspects as demographics, symptoms, physical signs and risk factors.

RESULTSAmong the 520 patients, DVT was found in 46 cases (9.7%). In patients with DVT, the duration of hospitalization was longer (P = 0.01), and the mechanical ventilation requirement increased (P < 0.001). Other indicators for patients with more possibility of DVT were immobility exceeding 3 days (P < 0.001); pneumonia as concomitance (P = 0.01); respiratory failure type II (P = 0.013); current smoking (P = 0.001). Lower extremity pain was more common in DVT cases in comparison to those without DVT (34.8% vs. 15.2%, P = 0.01).

CONCLUSIONSThe acute exacerbation of COPD patients, who were immobilized for over 3 days, complicated by pneumonia and had respiratory failure type II, had a higher risk of DVT. In addition, DVT detection awareness should be increased in cases that had a lower extremity pain.

This study was purposed to explore the expression of glucosylceramide synthase (GCS) in human leukemia cells and its relationship with multidrug resistance. RT-PCR was used to analyze peripheral blood samples from 53 leukemia patients with multidrug resistance/non-resistance, and to detect the expression level of GCS gene in HL-60 cells and HL-60/ADR cells, the expression level was compared with the level of mdr-1. The expressions of GCS protein and P-gp protein in HL-60 cells and HL-60/ADR cells were assayed by Western blot analysis. The results showed that the relative optical density ratio of GCS gene amplified bands in samples of leukemia patients with drug-resistance was significantly higher than that in samples of leukemia patients with drug non-resistance group (P < 0.05), meanwhile the significant enhancement of optical density value of GCS gene amplified bands accompanied by high expression of mdr-1 gene. Their correlation showed positive (P < 0.01, r = 0.6). The GCS mRNA and protein were overexpressed in HL-60/ADR cells, and their expression levels were obviously higher than that in HL-60 cells, meanwhile the expression of mdr-1 mRNA and P-gp also significantly increased in HL-60/ADR cells. It is concluded that the high level of GCS in leukemia patients possibly is associated with multidrug resistance of leukemia cells.
