We detected the seroprevalence of Toxoplasma gondii (T.gondii) in the wild birds in northeast China.The wild bird's blood was collected from the cutaneous ulnar vein and the serum was isolated and used for detection of anti T.gondii antibody by modified agglutination test (MAT).Results showed that totally 179 birds' serum samples were collected.Twenty serum samples (11.17％) were positive with T.gondii antibody,which belonged to 9 orders,17 families and 31 species.The seroprevalence against T.gondii was about 5.26％ (1/19) in Columbiformes,9.09％ (9/99) in Passeriformes,14.29％ (3/21) in Falconiformes,15.00％ (5/22) in Piciformes,16.67％ (1/6) in Coraciiformes,and 25.00％ (1/4) in Anseriformes.Based on their feeding behavior,the seroprevalence was 12.00％ (3/25) in carnivorous wild birds,10.60％ (15/141) in omnivorous wild birds,and 15.38％ (2/13) in the wild birds feeding on aquatic animals or plants.These wild birds also can be sorted as migratory and sedentary (non-migratory) according to their migration habits,and the serum positivity was 11.67％ (14/120),and 10.71％ (6/59) respectively.The seroprevalence against Toxoplasma gondii in wild birds in northeast China is about 11.17％,which indicates a common infection of Toxoplasma gondii in wild birds.

Objective:To observe autophagy induced by aminophylline in human peripheral blood T lymphocytes.Methods:Peripheral blood T lymphocytes from health adults were separated with Percoll(1.073 g/ml) and harvested by using nylon column.The cultured cells were divided into control group,aminophylline group(10-8～10-3mol/L,or 0.001 8～180 ?g/ml)and dexamethasone(DXM) group,and the rates of autophagy and apoptosis were analyzed by flow cytometry.Results:①The purities of T lymphocyte were 81.3%～94.5%。②In control group for 72 h cultivation,the autophagic rate of T lymphocytes was significantly lower than those of 10-5～10-3mol/L aminophylline group(P0.05);In 10-5mol/L aminophylline group,the autophagic rate of different T lymphocyte density after cultivation(0,24,48,72 h) had a tendency of increase along with time lasting and decrease of cell density,but the difference did not show significance.③There was significant statistic difference in incidence rate of apoptotic T lymphocytes between control and DXM group in 72 h cultivation(P=0.000);But there was no significant statistic difference in the rate of autophagic(P=0.481).Conclusion:10-3～10-5mol/L aminophylline can induce autophagy in peripheral blood T lymphocytes,10-3～10-8mol/L aminophylline could induce both autophagy and apoptosis,and there is no significant correlation between autophagy and apoptosis;DXM can induce apoptosis in peripheral blood T lymphocytes,which indicates different programmed cell death of T lymphocytes could be induced by different medicines.

Alimentary tract duplications are rare congenital anomalies that usually present in childhood and occasionally in adults. They are most common in the ileum, but can occur anywhere along the alimentary tract from the mouth to the anus. We report a 24-year-old woman who presented with a giant chylous ileum cyst duplication. To our knowledge, there is only one other report of a patient with a giant chylous cyst in the literature.

Objective: To investigate the immune reconstitution of HIV/AIDS patients and its influencing factors after receiving antiviral therapy (ART) in Hangzhou City, so as to provide insights into improving the treatment effects and quality of life in HIV/AIDS patients. Methods: A retrospective cohort of HIV/AIDS patients who began antiviral treatment between January 1, 2016 and August 31, 2021 and had a baseline CD4+T lymphocyte (CD4) counts of less than 500 cells/μL or a baseline CD4/CD8+T lymphocyte (CD8) ratio of less than 0.8 in Hangzhou City was followed up until August 31, 2023. Demographic information, antiviral therapy in formation, CD4 counts, and CD4/CD8 were collected from the Chinese Disease Prevention and Control Information System. A good immune reconstitution was defined as having CD4≥500 cells/μL and CD4/CD8≥0.8. The immune reconstitution status of HIV/AIDS patients were analyzed, and factors affecting immune reconstitution were identified using a multivariable Cox proportional risk regression model. Results: A total of 3 349 HIV/AIDS patients were enrolled, with a median age at ART of 31 (interquartile range, 20) years. There were 3 075 males (91.82%), 1 600 cases with college education and above (47.78%) and 2 455 cases at WHO clinical stage Ⅰ-Ⅱ(73.31%). There were 1 368 cases with good immune reconstitution, accounting for 40.85%, and the proportion of HIV/AIDS patients with good immune reconstitution that began ART in 2016 was the highest, reaching 51.90%. Multivariable Cox proportional risk regression model identified WHO clinical stage (Ⅰ-Ⅱ, HR=2.529, 95%CI: 2.023-3.162), timely ART (HR=1.196, 95%CI: 1.027-1.394), initial treatment regimen (TDF+3TC+NVP/EFV, HR=2.185, 95%CI: 1.891-2.524; integrase inhibitors, HR=8.509, 95%CI: 6.706-10.795), baseline CD4/CD8 (≥0.1, HR: 1.600-4.515, 95%CI: 1.061-6.661), baseline hemoglobin (<90 mg/dL, HR=0.327, 95%CI: 0.121-0.880), hepatitis B infection (HR=0.619, 95%CI: 0.457-0.840) and hepatitis C infection (HR=0.308, 95%CI: 0.099-0.956) as factors affecting immune reconstitution in HIV/AIDS patients. Conclusion The immune reconstitution in HIV/AIDS patients after ART is associated with WHO clinical stage, timely ART, initial treatment regimen, baseline CD4/CD8, baseline hemoglobin and hepatitis B or C infection.

The noninvasive measurement of liver stiffness (LS) was evaluated by transient elastography (FibroScan) and the possible influencing factors from the patients' clinical situations including age, gender, liver inflammation represented by alanine transaminase (ALT) and total billirubin (TBIL) level, HBV replication (HBV DNA loads), portal vein pressure (portal vessel diameter, PVD), splenic thickness (SPT) and body mass index (BMI) were analyzed in patients with chronic hepatitis B (CHB). A total of 466 patients including 31 patients with acute-on-chronic liver failure (ACLF), and 435 patients with chronic hepatitis B (CHB) among which 82 patients were diagnosed with liver cirrhosis (LC) by clinical manifestations and liver B-type ultrasonic inspection were enrolled at Tongji Hospital from April to December 2009. LS was measured by a FibroScan device (EchoSens, France). Simultaneously, ALT and TBIL levels, HBV DNA loads, PVD, SPT and BMI in all patients were also tested. Forty-one healthy volunteers served as controls. The values of LS were correlated positively with ages of CHB patients and significantly higher in males than in females. In patients with BMI>28 kg/m(2) (obesity) and abnormal levels of ALT and TBIL, LS values were significantly increased as compared with those having normal levels of ALT and TBIL. The patients with ACLF had the highest LS value. Furthermore, LS values in the patients with LC were significantly higher than those in patients without LC. It is concluded that noninvasive measurement of liver fibrosis by FibroScan provides an alternative method to evaluate liver fibrosis of patients with CHB. In order to properly illustrate the stiffness value taken by transient elastography, patients' gender should be taken into consideration and it is also suggested to avoid possible influencing factors including liver inflammation (high levels of ALT and TBIL) and obesity (high BMI).

Cervical spondylotic myelopathy (CSM) is a common cause of spinal cord dysfunction clinical disease. Surgery is the main therapeutic tool for CSM. However, there are obvious differences in clinical functional recovery after operation. For the past few years, the influence factors of prognosis in cervical spondylosis myelopathic has been widely concerned. Age, nerve function, course of desease, imaging findings,surgical method and related factors became the investigative point for prognosis of cervical spondylotic myelopathy. Present viewpoint showed that the older patient, preoperative worse nerve function, longer the course of disease would result in worse outcomes. Imaging examination maybe can indicate the prognosis, but the correlation is unclear. Selection of surgical method and approach should be based on the principles of sufficient decompression, stabilize the alignment of the cervical spine, keeping backward extension of cervical spine, maintain effective decompression, preventing complications. Therefore, the treatment of cervical spondylotic myelopathy should be on the basis of pathogenic condition and imaging examination at early stage and a suitable usrgical procedure should be performed to obtain a better prognosis.

BACKGROUND: Stem cell transplantation in repairing infarct myocardium and in improving cardiac function has been widely accepted. However, whether transplanted cells and host cells formed an effective electricity and mechanical couple, whether a relevant independent electrical system with contractile function formed or whether severe malignant ventricular arrhythmia formed, are still unclear.OBJECTIVE: To investigate electrophysiological abnormaltiy and left ventricular remodeling in rats with myocardial infarction following allogenic bone marrow mesenchymal stem cell (BMSC) transplantation.DESIGN, TIME AND SETTING: The randomized controlled animal study was performed at the Experimental Center, Guangxi Medical University from December 2005 to October 2008.MATERIALS: A total of 120 healthy Wistar rats were equally randomized into normal control, sham operation, saline control and cell transplantation groups. Healthy Wister rats aged 1 month were selected to harvest bone marrow.METHODS: At the third passage, rat BMSCs were collected and treated with 5-aza, and differentiated into cerdiomyocytes.BMSCs were labeled with DAPI at 2 hours before transplantation. In the saline control and cell transplantation groups, rat models of myocardial infarction were established by ligating the left anterior descending coronary artery. In the sham operation group, the coronary artery was not ligated, but only braid. At 7 days following ligation, BMSCs in the cell transplantation group at 2×10-1/L were infused into the edge and center of myocardial infarct region by multipoint injection. Rats in the other three groups were subjected to an equal volume of saline.MAIN OUTCOME MEASURES: Electrocardiogram and cardiac electrophysiology were performed. Ultrasonic cardiography was used to detect left ventricular function. Infarct size was determined. DAPl-labeled donor cell migration and distribution was observed with a fluorescence microscope.RESULTS: BMSCs could differentiate into cardiacmuscle cell-like cells which were capable of pulsing spontaneously, expressing cardiactoponin T and forming myofilament in vitro. Compared with the saline control group, PR interval, QRS duration and ventdcular effective refractory period shortened, ventricular fibrillation threshold increased at 4, 8 and 12 weeks (P < 0.05); left ventricular internal diameter at end-systole reduced, and left ventricular ejection fraction and shortening traction was significantly increased (P< 0.05). At 8 and 12 weeks, infarct size was significantly smaller (P < 0.05). At 4 weeks, DAPl-labeled BMSCs could be seen under the fluorescence microscope, and still could he detected at 12 weeks. However, the fluorescence became weak with prolonged time.CONCLUSION: BMSCs have the plasticity of differentiating into cardiac muscle cell-like cells, which can modulate theelectrophysiological abnormality and left ventricular remodeling following myocardial infarction.
