Rates and influencing factors of hospitalization after diagnosis among HIV infection cases in Yinzhou district of Ningbo, 2012-2020 / 中华流行病学杂志

Objective: To understand the hospitalization rates and influencing factors after diagnosis among HIV infection cases, based on real-world data in Yinzhou district of Ningbo. Methods: A retrospective cohort study was conducted based on the databases of National AIDS Comprehensive Response Information Management System and Yinzhou Health Information Platform. The information about the following-up results, antiviral treatment data, electronic records of inpatient of the HIV cases reported during 2012-2020 were collected to analyze the rates, causes and influencing factors of hospitalization. Results: Among the 763 HIV infection cases reported in Yinzhou from 2012 to 2020, the hospitalization rate was 6.95% (53/763), and the number of inpatient was 2.59 per 100 person years. The hospitalization rate and the number of hospitalization per 100 person years in HIV infection cases were 3.16% (10/316) and 0.81 in those aged <30 years, 6.07% (15/247) and 1.59 in those aged >30 years, 7.86% (11/140) and 4.05 in those aged >45 years and 28.33% (17/60) and 17.40 in those aged ≥60 years respectively. Logistic multivariate regression analysis indicated that being aged ≥60 years was the influencing factor for hospitalizations in HIV infection cases (аOR=14.44, 95%CI:3.57-58.46). The hospitalization rates due to AIDS related diseases, cardiovascular diseases and metabolic diseases, and other diseases were 1.83% (14/763), 1.05% (8/763), and 3.93% (30/763), respectively. Conclusions: The hospitalization burden due to HIV infection was still mainly caused by those aged ≥60 years in Yinzhou, similar to that in general population and less proportion of hospitalizations were due to AIDS related diseases. The overall increase of hospitalizations due to AIDS was not obvious in Yinzhou.

Rapamycin protect puromycin amino nucleoside induced podocyte injury by up-regulating autophagy / 中国免疫学杂志

Objective:To explore the protective effect of rapamycin and the role of autophagy on podocyte injury induced by pu-romycin amino nucleoside.Methods:The mice podocytes cell 5(MPC5)were randomly divided into four groups:Control group,PAN group(50 μg/ml PAN);rapamycin group(RAP group,100 ng/ml,200 ng/ml,300 ng/ml rapamycin)and PAN+rapamycin group (PAN+RAP group,treated with rapamycin before PAN).The apoptosis of podocytes were detected by Annexin V/PI.Transmission electronic microscopy was used to observe the formation of autophagosome.The expression of autophagic markers,LC3,p62,and 4EBP1,P70S6K,mTOR were detected by Western blot.Results: The podocyte apoptotic rate was significantly decreased when the podocytes were treated with rapamycin compared with PAN group.Further,more autophagosomes appeared in cytoplasm of podocytes in RAP and PAN+RAP group compared with PAN group.And the expression of LC3Ⅱ was significantly increased in rapamycin treated podocytes,whereas the expression of p62 was decreased markedly.Phosphorylation of mTOR,4EBP1 and P70S6K was decreased rapamycin treated groups.Conclusion: Podocyte autophagy was inhibited by PAN, and the apoptosis of podocytes was promoted.Rapamycin protect puromycin amino nucleoside induced podocyte injury by upregulating autophagy and it may be concerned with mTOR 4EBP1 and P70S6K signaling pathway.

Peripheral blood cell variations in cirrhotic portal hypertension patients with hypersplenism

OBJECTIVE@#To explore peripheral blood cell variations in hepatic cirrhosis portal hypertension patients with hypersplenism.@*METHODS@#Clinical data of 322 hypersplenism patients with decreased peripheral blood cells, admitted with cirrhotic portal hypertension, was retrospectively studied over the last 17 years.@*RESULTS@#In 64% (206/322) of patients, more than 2 kinds of blood cell were decreased, including 89 cases of pancytopenia (43.2%), 52 cases of WBC + PLT decrease (25.2%), 29 cases of RBC + PLT decrease (14.1%), and 36 cases of WBC + RBC decrease (17.5%); in 36% (116/322) of patients, single type blood cell decrease occurred, including 31 cases of PLT decrease (26.7%), 29 cases of WBC decrease (25%) and 56 cases of RBC decrease (48.3%). Of 227 routine bone marrow examinations, bone marrow hyperplasia was observed in 118 cases (52.0%), the remainder showed no hyperplasia. For the distinct scope and extent of peripheralblood cell decreases, preoperative blood component transfusions were carried out, then treated by surgery, after whole group splenectomy, the peripheral blood cell count was significantly higher (P<0.05).@*CONCLUSIONS@#Of portal hypertensive patients with splenomegaly and hypersplenism, 64% have simultaneous decrease in various blood cells, 36% have decrease in single type blood cells, 52% of patients have bone marrow hyperplasia. A splenectomy can significantly increase the reduction of peripheral blood cells.

Social participation and needs for rehabilitation services of the disabled in Guangdong Province HUANG / 中华物理医学与康复杂志

Objective To explore the relationship between social participation and needs for rehabilitation of the disabled in Guangdong Province and to make a proposal for developing the rehabilitation strategies. Meth-ods The data of the Second National Sample Survey of Disabled Persons in Guangdong Province was used in this study. Ranked data analysis was made with the sub-items of the social participation assessment and the main needs of the disabled individuals. Results Significantly statistical differences were revealed with regard to the constitu-ent ratio of needs for rehabilitation services among people with different degrees of difficulties in social participation caused by hearing and visual impairments as well as physical and mental disabilities. No significant difference was found in terms of the constituent ratio of rehabilitation needs among those with difficulties in speech and those with psychiatric diseases. The major rehabilitation needs focused on medical service, assistive apparatus support and functional trainings. Conclusions The rehabilitation needs were different among different categories of disabled persons. Rehabilitation services should be provided accordingly.

Evaluation of living donor liver transplantation for patients with hepatocellular carcinoma / 中华肝脏病杂志

<p><b>OBJECTIVE</b>To evaluate the donor risks and potential recipient benefits of living donor liver transplantation (LDLT) for adult patients with hepatocellular carcinoma (HCC).</p><p><b>METHODS</b>From January 2002 to December 2006, a total of 27 LDLT for HCC patients were performed in our center, of which 25 received right lobe grafts and 2 received dual grafts. The clinical and follow-up data of these 27 recipients and 29 donors were analyzed retrospectively.</p><p><b>RESULTS</b>Of the 29 donors, the overall complication rate was 17.24% (5 cases). Two cases (6.90%) experienced major complications (one with intra-abdominal bleeding and one with portal vein thrombosis) and three cases (10.34%) experienced minor ones (fat necrosis and infection of the surgical skin wound in one, pleural effusion in another and transient chyle leakage in the third). All donors were fully recovered and returned to their previous work. No recipients developed small-for-size syndrome. The overall HCC patients survival rate at 1- and 3-years was 84.01% and 71.40%, respectively, similar to that of patients undergoing LDLT for various nonmalignant diseases during the same period (P > 0.05).</p><p><b>CONCLUSION</b>Although further study is needed to fully assess the risks and benefits of LDLT for the HCC patients and donors, our present results preliminarily suggest that LDLT offers an acceptable chance and duration of survival in patients with HCC, and it is a relatively safe procedure.</p>

Apoptosis in male germ cells induced by testicular denervation / 中华男科学杂志

<p><b>OBJECTIVE</b>To evaluate the role of spermatic nerves in the regulation of spermatogenesis.</p><p><b>METHODS</b>Fifty-four mature SD male rats (350-375 g) were randomized into a sham operation group (SO) and three experiment groups, and the latter underwent bilateral surgical removal of the superior spermatic nerve (SSN) or/and the inferior spermatic nerve (ISN). The animals were killed 1 month and 2 months after the operation. HE stain was used to observe spermatogenesis. Transmission electron microscopy and terminal deoxynucleotidyl transferase-mediated dUTP nick end-labeling (TUNEL) were employed to detect apoptosis.</p><p><b>RESULTS</b>Impaired spermatogenesis was observed 2 months after the operation, with only Sertoli cells and a few spermatogonia remaining in the regressed tubules in all the treatment groups. The abnormal tubules in the SSN, ISN and SSN + ISN denervated testes accounted for (13.25 +/- 2.03)%, (11.0 +/- 4.36)% and (34.17 +/- 3.78)% respectively. Chromosome condensation and fragmentation in the germ cells were observed under the electron transmission microscope in all the denervated testes. TUNEL showed the spermatogonia and Leydig cells to be apoptotic in all the denervated testes and the incidence of the apoptotic cells in the SSN + ISN denervated testes was significantly higher than in the SSN or ISN denervated ones.</p><p><b>CONCLUSION</b>Spermatic nerves play an important role in spermatogenesis.</p>
