Objective To study the immune function of the subpopulation of T helper lymphocyte(Th), including Th1 and Th2 cells in myasthenic thymus and peripheral blood (PB).Methods Enzyme-linked immunospot (ELISPOT) method is adopted to detect the acetylcholine receptor (AChR)-reactive interleukin-2(IL-2)-, interleukin-4 (IL-4)-, interleukin-10 (IL-10)-, interferon-gamma(IFN-?)-secreting cell numbers in thymus and peripheral blood (PB). Results The AChR-reactive IL-2-,IL-4-,IL-10-, IFN-?-secreting cell numbers were increased in thymus as well as the AChR-reactive IL-10-, IFN-?-secreting cell numbers in PB. There is a positive correlation between thymus and PB in MG for the AChR-reactive IL-4-, IL-10-secreting cell numbers. After treatment, the AChR-reactive IL-2-,IL-4-, IFN-?-secreting cell numbers were decreased in PB, while there were 1 case and 2 cases showing a decrease and an increase in AChR-reactive IL-10-secreting cell number, respectively.Conclusions The immune dysfunction of the Th1 and Th2 subpopulation existed in the thymus and PB of MG, and the AChR-reactive IL-4-, IL-10-secreting cell numbers might be served as parameters to evaluate the degree of the immune dysfunction in the MG thymus. The role of the IL-10 in pathogenesis of MG needs further study.

Objective To describe the method and clinical result of super sural neuromusculocutaneous flap grafting plus catheter irrigation in the treatment for chronic lateral malleolus osteomyelitis. Methods From March 2000 to March 2008, 17 cases, male 14, femal 3, 21 to 75 years old (average 43-year-old),were underwent reversed saphenous musculocutaneous island flap after wide excision of lateralmalleolus lesion. The cause of lateral-malleolus lesions was trauma. The smallest flap was 5 cm× 6 cm and the largest was 7 cm × 11 cm. Catheter irrigation was used in all cases. Results Follow-up ranged from 12 to 96 months, average 49 months. After operation, the wounds were irrigated with sensitive antibiotics 1 to 2.5 months(average 49 days), and all flaps were survived. Except 2 cases, the other 15 were healed in 1 month.The 2 cases were not healed at first stage. According to the lab result,we changed the antibiotic, and in 2.5 months, we took off the catheter. Conclusion To deal with the chronic traumatic lateral-malleolus osteomyelitis, super sural neuromusculocutaneous flap grafting plus catheter irrigation is approprite and effective.

Objective To examine the effect of risperidone on the mental symptoms after frontotemporal brain contu?sion. Methods Sixty cases with mental symptoms after frontotemporal brain contusion were recruited from Jan 2009 to Dec 2011 and were randomly divided into control group and treatment group. The patients in the control group were giv?en vitamin B1 60mg/d, while the patients in the treatment group were given risperidone 1mg/d. Both groups were treated for 1 month. Positive and negative symptom scale (PANSS) and symptom scale (TESS) were used to evaluate the efficacy and adverse reactions of treatment. Results The PANSS score was significantly lower in the treatment group than in con?trol group at 1, 2, 3 and 4 weeks following treatment(difference between groups:F=48.12 ,P<0.0001;Time difference:F=290.99 ,P<0.0001; Interaction between group and time: F=11.91,P<0.0001 ). After time-adjustment, the PANSS score was significantly lower in the treatment group than in control group at 2, 3 and 4 weeks following treatment. In the course of treatment, the patients in both groups had varying degrees of headache, nausea, weight gain and Beckoning. These side effects were alleviated through symptomatic treatment. Conclusion Risperidone can significantly improve psy?chiatric symptoms in patients with frontotemporal brain contusion with satisfactory safety.

Objectives To explore the brain white matter integrity among the patients with buprenorphine tables,scopolamine and promethazine solution(BSP) dependence after abstinence.Methods BSP-dependent patients( n=16)and age/eduction-matched healthy control subjects ( n=18) were assessed by diffusion tensor imaging (DTI) after 3 days,1 month and 2 months of abstinence.White matter (WM) integrity was measured with DTI as fractional anisotropy ( FA),an index of intravoxel orientational coherence of white matter fibers.Results Compared with health controls,FA values were significantly lower in frontal,parietal,temporal and corpus callosum in the BSP addicts after 3-day withdrawal (P＜0.001,uncorrected).Increased FA values in left superior frontal cortex,right medial frontal gyms and fight inferior parietal gyrus were found in BSP users after 2 months of abstinence (P ＜0.001,uncorrected).However,no significant difference was found between these BSP addicts after 1-month abstince.Compared with health controls,BSP dependent subjects still exhibited significantly lower FA in the corpus callosum,frontal,parietal and temporal WM after 2-month withdrawal (P ＜ 0.001,uncorrected ).Conclusion The abnormalities showed less recovery in BSP dependent individuals with abstinence in white matter that suggests that rehabilitation time should be further prolonged for BSP addicts and emphasis cognitive-behavioral therapy to assist BSP abusers rebuild social functions.

Objective To analyze the factors which influence the treatment compliance of hypertensive patients in health management. Methods Data of 6 325 hypertensive patients who received physical examination in our department were collected; 4 132 male cases and 2 193 female were included, their ages ranged from 28 to 84 years old;the average age was 61.2 ± 5.8 years. The patients of the health intervention group were randomly divided into 3 groups (group 1, group 2 and group 3). They were provided with regular health management (including weight management, catering management, sports management, medication management and monitoring of blood pressure), respectively, given different frequency of telephone follow-up (1 time per 2 months, 1 time per month, and 1 time per month), evaluating treatment compliance. All the results were analyzed and compared respectively according to the level of education, age and mental status. Data of 1 892 hypertensive patients who received outpatient services were enrolled as the control group. Among them, 4 132 were male and 2 193 were female, aged 28-84 years old, average (61.2 ± 5.8) years old. They received the traditional outpatient follow-up (outpatient service review and health education), their treatment compliance, timely correcting unhealthy lifestyle and medication method and self-testing blood pressure were evaluated. ANOVA and chi square test were used to analyze the treatment compliances and blood pressure control rates of the two groups. Result Compared with the control group, health intervention for hypertension patients could significantly improve the treatment compliance and blood pressure control rate(64.8%vs. 41.3%, 56.7%vs. 29.6%;χ2=2.827,1.382;P=0.032,0.007). Comparing the results of telephone follow-up frequency, the treatment compliance and blood pressure control rate of the 3 intervention groups were higher than those of the two other groups(77.3%vs. 65.4%, 51.7%,χ2=3.414,P=0.041;69.6% vs. 57.3%, 43.2%,χ2=2.763,P=0.028). The treatment compliance of patients with high education level was significantly higher than that of patients with low education level(68.7% vs. 59.1%, 46.4%,χ2=3.257,P=0.037;60.1%vs. 47.2%,32.8%,χ2=1.234,P=0.009). And the treatment compliance of patients with good mental state was significantly higher than that of patients with anxiety(Intervention group1:64.3%vs. 55.1%,41.9%,31.0%,χ2=2.257, P=0.016;59.4%vs.46.1%,20.9%,21.8%,χ2=3.34 5 P=0.021;Intervention group2:75.5%vs. 64.3%,51.8%,41.2%,χ2=2.932, P=0.030;68.3%vs.57.1%,39.2%, 32.1%,χ2=2.382, P=0.032;Intervention group3:86.5% vs.73.2%,62.6%,52.4%,χ2=2.435, P=0.026;75.2% vs. 68.0%,51.7%,43.3%,χ2=3.251, P=0.036). Conclusion More frequently follow-up can improve the treatment compliance and control rate of blood pressure in hypertensive patients;education, age and psychological condition are factors influencing treatment compliance in hypertensive patients.

Objective To understand the genotyping of human immunodeficiency virus (HIV) co-infected hepatitis C virus (HCV) patients in Yunnan Province, and to analyze the differences in viral load, biochemical indicators, and blood routine indicators among different genotypes, in order to provide a laboratory basis for the diagnosis and clinical treatment of HIV/HCV co-infected patients. Methods From November 2022 to June 2023, the serum samples and basic information of patients diagnosed with HIV/HCV co-infection were collected in the antiviral outpatient clinic of Yunnan Provincial Hospital of Infectious Diseases. The HCV viral load was detected by one-step qRT-PCR amplification, the positive samples were sequenced, and genotyping was determined based on NS5 gene sequence. The differences in biochemical and blood routine indexes between HIV patients co-infected with different HCV genotypes and low/high viral loads were analyzed. Results A total of 126 HIV/HCV co-infected patients were collected, including 20 HCV genotype 1 (15.9%), 91 HCV genotype 3 (72.2%), and 15 HCV genotype 6 (11.9%). The maximum and minimum viral load of the three HCV genotypes were as follows: HCV type 1 (1.0×108, 4.8×104 IU/mL), HCV type 3 (2.2×108, 2.9×102 IU/mL), and HCV type 6 (8.1×107, 6.8×104 IU/mL). The results showed that there was no significant difference between HIV co-infection with different genotypes of HCV and three HIV treatment schemes, including nucleoside reverse transcriptase inhibitors+integrase strand transfer inhibitors (NRTIs+INSTIs), nucleoside reverse transcriptase inhibitors+non-nucleoside reverse transcriptase inhibitors (NRTIs+NNRTIs) and nucleoside reverse transcriptase inhibitors+protease inhibitor (NRTIs+PLs), and the viral load of patients (P>0.05). The analysis of biochemical indexes such as total bilirubin (TBIL), direct bilirubin (DBIL), alanine aminotransferase (ALT), aspartate aminotransferase (AST), creatinine (CREA), and blood routine indexes such as white blood cell (WBC), red blood cell (RBC), hemoglobin (HGB), platelet (PLT), mean corpuscular hemoglobin (MCH) and mean corpuscular hemoglobin concentration (MCHC) among different HCV genotypes and low/high viral loads showed that there was no significant difference in biochemical indexes and blood routine indexes between low/high viral loads of HIV co-infected HCV patients (P>0.05); however, the biochemical indicators TBIL, IBIL and MCHC were significantly different statistically between patients with genotype 3 HCV infection and those with genotype 1 HCV infection (P<0.05), while other biochemical and blood routine indexes were not statistically different among different HCV genotypes (P>0.05). Conclusions There are six subtypes of HCV co-infection in HIV patients in Kunming, Yunnan Province, including three genes of genotype 1, 3, and 6. Among them, genotype 3 HCV is the main prevalent genetic virus among HIV co-infected populations. The TBIL, IBIL and MCHC values of HIV patients co-infected with HCV type 3 are different from those infected with HCV type 1.
