OBJECTIVE: To investigate the effects of Shenshuning Recipe (SSNR) on gene expression of hepatocyte growth factor (HGF) in renal tissues in rats with glomerulosclerosis. METHODS: Glomerulosclerosis was induced in 42 rats by unilateral nephrectomy and intravenous injection of doxorubicin. Then these 42 rats were randomly divided into three groups: untreated group, SSNR-treated group and benazepril-treated group. Another eight rats were included into sham-operation group. The rats in the SSNR-treated group and the benazepril-treated group were fed SSNR or benazepril respectively for 8 weeks. The levels of 24 h urine protein (Upr), serum creatinine (Cr) and blood urea nitrogen (BUN) of rats in each group were examined. The renal morphological changes were observed under microscope, and the diameter of glomerular capillary, mesangial matrix and glomerulosclerosis index were analyzed by image analysis software. Reverse transcription-polymerase chain reaction (RT-PCR) method was used to detect the gene expression of HGF in the renal tissues. RESULTS: The levels of 24 h Upr, serum Cr and BUN in the untreated group were remarkably increased than those in the sham-operation group (P<0.01). The pathological morphological changes in the untreated group showed that the glomerulosclerosis was diffused around the renal tissue and the capillaries were shrunk. The expression level of mesangial matrix was up-regulated and the glomerulosclerosis index was 3.32+/-0.35. The expression level of HGF mRNA in the untreated group was obviously lower than that in the sham-operation group (P<0.05). The levels of 24 h Upr, serum Cr and BUN in the SSNR-treated group and the benazepril-treated group were remarkably decreased as compared with those in the untreated group, while the expression levels of HGF mRNA were both obviously higher than that in the untreated group (P<0.01). The pathological morphological changes in the SSNR-treated group and the benazepril-treated group were both alleviated. There was no significant difference in therapeutic effect between the SSNR-treated group and the benazepril-treated group. CONCLUSION: Shenshuning Recipe can up-regulate the expression of HGF mRNA, decrease the mesangial matrix, and improve the renal function, so that it may retard the development of glomerulosclerosis.

AIM: To explore the relationship between caspase activation and the evasion of Legionella from macrophage elimination through a Legionella-infected macrophage model. METHODS: After infected by Legionella, the activity of caspase 3 in macrophages was analyzed by confocal microscopy as well as fluorescence reader. Growth and replication of Legionella in macrophage was assayed. Replication of Legionella was analyzed again to see the effect of caspase 3 inhibition on the growth of Legionella after use of caspase 3 inhibitor. RESULTS: Both confocal microscopy and caspase 3 fluorescent substrate analysis showed that Legionella virulent strain had powerful capability of activating caspase 3 while the mutant non-virulent strain did not have this capability. The virulent strain highly replicated in macrophages and the replication was significantly inhibited by caspase 3 inhibitor. CONCLUSION: Our results indicate that the intracellular caspase 3 is activated shortly after infection by Legionella virulent strain. The evasion of Legionella from the elimination of macrophages may be mediated by caspase 3 activation to a great degree.

AIM: To explore the effect of TNF-related apoptosis inducing ligand (TRAIL), a new apoptotic inducing molecule on the biological activity of hepatocarcinoma cell line. METHODS: The expression of membrane binding TRAIL on HepG2 cells was detected by immuno-cytochemistry. Quantity of secretory TRAIL was assayed by ELISA method. The cytotoxicity and apoptosis induced by TRAIL was detected by MTT and TUNEL method, respectively. The telomerase activity of HepG2 cells was detected by TRAP-PCR assay kit. The expression of hTERT, the catalytic subunit of telomerase, was detected by FCM. RESULTS: TRAIL was constitutively expressed on the membrane of HepG2 cell line. Soluble TRAIL was also expressed to a certain degree. Cytotoxicity assay showed that TRAIL significantly inhibited the growth of hepatocarcinoma cells. TUNEL assay indicated that TRAIL induced apoptosis in hepatocarcinoma cells. Detection of telomerase activity showed that TRAIL inhibited telomerase activity and the expression of telomerase catalytic subunit. CONCLUSION: TRAIL is an effective molecule to inhibit the growth of hepatocarcinoma through multiple pathways, such as inducing apoptosis and inhibiting the activity of telomerase.

From September 2020 to August 2021, 34 general practice trainees in Xuanwu Hospital, Capital Medical University were were randomly divided into the control group and trial group with 17 in each group. The control group adopted the traditional clerkship method for outpatient clinical teaching; the trial group independently received patients with the supervision of clinical instructors, and the Leicester assessment package (LAP) was used for evaluation and training. The performance of two groups were assessed using the Beijing General Practitioner's Graduation Assessment and Admissions Patient Score Sheet. The LAP training was also given to control group at the late stage of the study, and the application of LAP was assessed with a questionnaire survey in two groups of trainees. The results showed that the performance of trial group was better than that of control group in terms of medical history collection [(23.12±1.05) vs. (21.18±0.88), t=-5.82, P<0.01 ], physical examination [(24.88±1.62) vs. (23.12±1.58), t=-3.22, P< 0.01 ], case analysis [(22.94±0.90) vs. (20.82±0.73), t=-7.55, P<0.01 ] and total score [(86.59±2.65) vs. (80.12±2.45) t=-7.40, P<0.01]. For assessment of LAP, all 34 trainees gave 5 points in items of improving patient care, knowledge and skills, communication skills, professional quality, reception skills, clinical thinking, clinical judgment, decision-making skills, and learning interest with the application of LAP in outpatient clinical teaching; the satisfaction of the trainees on the pertinence, teaching effect and LAP training method of the instructing physicians was 100% (34/34). It is suggested that the application of LAP for evaluation and implementation in general practice outpatient teaching will help to improve the teaching quality and the patient receiving ability of general practitioners.

OBJECTIVETo compare follow-up and administration of HIV-infected local Chinese and Burmese in Dehong prefecture of Yunnan province, for scientific development of prevention and control measures.

METHODS14 270 HIV-infected local Chinese and 5 436 HIV-infected Burmese reported from 1989 to December 31, 2013 in Dehong prefecture were recruited as the subjects of study, comparing the differences of follow-up and management, CD4⁺ T lymphocyte count tests and antiretroviral therapy (ART) between the two groups.

RESULTSThe proportion of HIV-infected Burmese identified in Dehong prefecture was 27.6% (5 436/19 706) during 1989-2013. The number had been growing rapidly from 17.1% in 1989-2003, 12.4% in 2004 and 14.7% in 2005 to over 51.4% in 2012, hitting 59.4% in 2013 (trends χ² = 1 732.84, P < 0.000 1). The proportion of HIV-infected Burmese among case reports of various characteristics kept rising over the years. By the end of 2013, 8 095 HIV-infected local Dehong residents and 5 326 HIV-infected Burmese were still alive. 95.8% of them were under follow-up, 88.5% having CD4⁺ T lymphocyte count tests, and 78.3% under ART. Among the HIV-infected B urmese, only 19.2% of them were under follow-up, 13.0% having CD4⁺ T lymphocyte count tests, and 6.1% under ART, significantly lower than the local Dehong residents (P < 0.000 1).

CONCLUSIONThe proportion of follow-up and administration, CD4⁺ T lymphocyte count tests, and ART of HIV-infected Burmese was low in Dehong prefecture, Yunnan province, which called for more effective follow-up and administration measures.

OBJECTIVETo understand HIV rival suppression and drug resistance (HIVDR) among AIDS patients who were receiving antiretroviral treatment (ART) in Dehong prefecture, Yunnan province.

METHODSAll AIDS patients who were aged over 15 years and with experience more than six months on ART by the end of 2012 in Dehong prefecture, were enrolled to receive testing for HIV viral load in plasma and genetic mutations associated with HIVDR.

RESULTSA total of 4 390 AIDS patients were qualified for the study according to the selection criteria, of whom 3 964 (90.3%) finally participated in the study. Among them, 2 307(58.2%) had CD₄(+) cell counts more than 350 cells/mm³. 3 169 (79.9%) patients showed undetectable plasma HIV viral load which was lower than the detection threshold. Those who had the following factors as:resided in Ruili city, being female, older than 45 years of age, married, heterosexually infected with HIV, having received ART more than 5 years, and CD₄(+) cell counts >500 cells/mm³, were more likely to have undetectable plasma virus load, with the differences statistically significant. 402 (10.1%) patients had plasma viral load ≥ 1 000 copies/ml, of whom 353 (87.8%) were successfully amplified and examined for HIVDR. Among them, 198 (56.1% ) were identified to bear genetic mutations associated with HIVDR. Most mutations were related to the resistance to nucleotide reverse transcriptase inhibitors (NNRTIs) or non-nucleotide reverse transcriptase inhibitors (NNRTIs), with M184V and K103N most frequently seen. 12 patients (3.4%) were found to have mutations resistant to protease inhibitors (PI). Data from multiple logistic regression analysis indicated that the period of receiving ART and the initial ART regimen could both significantly predict the occurrence of HIV resistance.

CONCLUSIONViral suppression was highly achieved among ART-prescribed AIDS patients in Dehong prefecture,Yunnan province. However, among those who did not show effective viral suppression, the proportion of HIVDR was high, underscoring the needs for health education so as to improve the adherence to drugs as well as for improving testing for viral load and HIVDR among AIDS patients.

ObjectiveTo investigate the demographic characteristics， high-risk behavior and first CD4⁺T cell（CD4 cell） counts among newly reported HIV-infected Burmese in Dehong Dai Jingpo Autonomous Prefecture （Dehong Prefecture） from 2019 to 2020. MethodsA cross-sectional survey was conducted among newly reported HIV-infected Burmese cases in Dehong Prefecture from 2019 to 2020 to collect related information and measure their first CD4 cell counts. ResultsAmong 1 228 HIV-infected Burmese cases， 846 （68.9%） were males and 382 （31.1%） were females； 445 （36.2%） were from Kachin， and 210（17.1%） were from Shan. Of them， 960 cases （78.2%） had participated in the first CD4 cell counts testing， and 405 cases （42.2%） had a first CD4 cell counts <350 cells·μL^-1. In the multivariable logistic regression analysis， age ≥30 years （adjusted OR=1.44， 95%CI： 1.07‒1.92） and history of illicit drug use in Myanmar （adjusted OR=0.41， 95%CI： 0.21‒0.79） were independently associated with first CD4 cell counts <350 cells·μL^-1. ConclusionThe first CD4 cell counts are generally low among newly reported HIV-infected Burmese in Dehong Prefecture， especially those aged ≥ 30 years and with a history of intravenous drug use in Myanmar. Therefore， early detection of HIV infection should be strengthened for timely intervention and treatment management among Burmese.

ObjectiveTo determine the characteristics， viral load and immunological status of HIV-infected persons and their spouses who became HIV-positive， and the reasons for HIV seroconversion in 55 HIV discordant couples in Dehong Dai and Jingpo Autonomous Prefecture （Dehong Prefecture）， Yunan Province. MethodsData on the 55 couples meeting the criteria of having a previously positive spouse were retrieved from the AIDS Integrated Prevention and Control Data Information System of the China Disease Control and Prevention Information System during 2015-2021. General socio-demographic information， age at diagnosis， exposure history， CD4⁺T lymphocyte count， and antiviral treatment were collected. Descriptive analysis and chi-square test were used to compare the distribution of pre-HIV-positive spouses and their HIV seroconverted spouses. ResultsA total of 55 spouses from HIV discordant couples had HIV seroconversion. Of them， 72.7% （40/55） of pre-HIV-positive spouses were husbands. The most recent CD4⁺T lymphocyte count in the pre-HIV-positive spouses was （328.31±246.27） cells·μL^-1 at the time of diagnosis of their seroconverted spouses， of which 36.3% （20/55） had a CD4⁺T lymphocyte count of less than 200 cells·μL^-1. Furthermore， of those pre-HIV-positive spouses with low CD4⁺T lymphocyte count， 45.0% （9/20） had an undetectable viral load， 15.0% （3/20） <400 copies·mL^-1， and 25.0%（5/20） ≥400 copies·mL^-1. Additionally， 16.4% （9/55） of the pre-HIV-positive spouses did not have a viral load test. The main reasons for HIV seroconversion among HIV-negative spouses in the discordant couples were poor condom use， poor compliance with antiviral therapy， and treatment discontinuation. ConclusionThe follow-up management of HIV discordant couples should be strengthened in Dehong Prefecture， especially the monitoring of viral load levels and immunological status of pre-HIV-positive spouses， to improve their compliance with antiviral therapy and reduce treatment discontinuation， which would effectively prevent and control HIV transmission between spouses.
