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).

Objective To establish a stable,repeatable and long-lasting rat model of myocardial infarction,and to evaluate the feasibility of monitoring electrophysiological changes and left ventricular function after myocardial infarction by electrocardiography (ECG) and ultrasonic cardiography(UCG). Methods Wistar rats were ligated on the left anterior descending coronary artery after anaesthesia with 10% chloral hydrate and machinery assisted respiration. Then they were monitored by ECG and UCG afer 4,8 and 12 weeks,and were sacrificed and pathologically examined at 12 weeks after operation. Results The rat model of myocardial infarction was established with a survival rate of 83.3% at 72 hours after the operation and 73.3% at 12 weeks after the operation. In the myocardial infarction group,the PR,QRS,QT and QTc intervals were statistically significantly longer than that in the sham operation group. UCG showed that the left ventricular internal diameter at end-diastole (LVIDd) and the left ventricular internal diameter at end-systole (LVIDs) were statiscally significantly higher in the infarction group,and the ejection fraction (EF) and fractional shortening (FS) significantly lower than those in the sham operation group. Long-lasting pathological changes can be seen in the tissues at 12 weeks after operation. Conclusions The method used in the present study is an simple,less injurious and highly successful technique,and the changes in electrophysiology and left ventricular function can be well monitored by ECG and UCG at different times during this period.
