Objective: To analyze the survival time of reported HIV/AIDS and influencing factors of Yunnan Province from 1989 to 2021. Methods: The data were extracted from the Chinese HIV/AIDS comprehensive response information management system. The retrospective cohort study was conducted. The life table method was applied to calculate the survival probability. Kaplan-Meier was used to draw survival curves in different situations. Furthermore, the Cox proportion hazard regression model was constructed to identify the factors related to survival time. Results: Of the 174 510 HIV/AIDS, the all-cause mortality density was 4.23 per 100 person-years, the median survival time was 20.00 (95%CI:19.52-20.48) years, and the cumulative survival rates in 1, 10, 20, and 30 years were 90.75%, 67.50%, 47.93% and 30.85%. Multivariate Cox proportional risk regression model results showed that the risk of death among 0-14 and 15-49 years old groups were 0.44 (95%CI: 0.34-0.56) times and 0.51 (95%CI:0.50-0.52) times of ≥50 years old groups. The risk for death among the first CD4⁺T lymphocytes counts (CD4) counts levels of 200-349 cells/μl, 350-500 cells/μl and ≥501 cells/μl groups were 0.52 (95%CI: 0.50-0.53) times, 0.41 (95%CI: 0.40-0.42) times and 0.35 (95%CI: 0.34-0.36) times of 0-199 cells/μl groups. The risk of death among the cases that have not received antiretroviral therapy (ART) was 11.56 (95%CI: 11.26-11.87) times. The risk for death among the cases losing to ART, stopping to ART, both losing and stopping ART was 1.66 (95%CI:1.61-1.72) times, 2.49 (95%CI:2.39-2.60) times, and 1.65 (95%CI:1.53-1.78) times of the cases on ART. Conclusions: The influencing factors for the survival time of HIV/AIDS cases were age at diagnosis in Yunnan province from 1989 to 2021. The first CD4 counts levels, antiretroviral therapy, and ART compliance. Early diagnosis, early antiretroviral therapy, and increasing ART compliance could extend the survival time of HIV/AIDS cases.

Short-term intermittent fasting (IF) is beneficial to weight control in patients with nonalcoholic fatty liver disease, but the impact of long-term IF is not clear. In this study, healthy C57BL/6N mice with 4-month alternate day fasting (ADF) were used to study the effects of long-term IF on systemic and liver lipid metabolism. The results showed that, compared with the Ad Libitum group, the weight and food conversion rate of mice in the ADF group were markedly decreased and increased respectively, and the liver index and the liver content of triglyceride were significantly increased by pathological examination. qRT-PCR analysis revealed that the mRNA expression of the lipogenesis gene Pparγ and lipolysis gene Atgl was up-regulated in the ADF group (P < 0.05). Western blot analysis showed that the ratio of microtubule associated protein LC3-II/LC3-I was increased, while the abundance of autophagy adaptor protein p62 was decreased in the ADF group. In addition, autophagy signal positive regulation key factor AMPK phosphorylation was increased (P < 0.05), and negative regulation factor mTOR phosphorylation was decreased (P < 0.05) in the ADF group, indicating that hepatocyte autophagy activity was elevated. Taken together, ADF for 4 months results in an excessive liver triglyceride accumulation, accompanied by a marked decrease in liver mTOR phosphorylation and a significant increase in hepatic autophagy.

Objective:To characterize and compare the chemical information of four extracts of Qingre Chushi (QRCS) decoction by liquid chromatography-mass spectrometry (LC-MS), and combine the chemical information of the four extracts with their results of anti-inflammatory effect for a multivariate statistical analysis, in order to identify the compounds directly relating to the anti-inflammatory effects of QRCS decoction. Method:Four extracts of QRCS decoction were characterized by UPLC-Q-TOF-MS:①ethanol extract+water extract,② ethanol extract+supernatant after water extraction and alcohol precipitation, ③ ethanol extract+precipitation after water extraction and alcohol precipitation,and ④ standard decoction. On the basis of the results of inhibition of the four above extracts on xylene-induced ear swelling in mice,multivariate statistical analysis[principal component analysis (PCA) and orthogonal partial least squares-discriminant analysis (OPLS-DA)] were carried out to lock the chromatographic peaks with significant differences between group ① (the best pharmacological action group) and group ④ (standard decoction group). According to the accuracy of quasi-molecular ion and fragment ion data,and the reference materials and literature data,those chromatographic peaks were identified. Result:PCA could cluster the four extracts of QRCS decoction,and the differences between groups was reflected in the distance between groups. Group ④ (standard decoction) had the most significant differences with the other three groups, especially in the first principal component; group ① (ethanol extract+water extract),group ② (ethanol extract+supernatant after water extraction and ethanol precipitation) and group ③ (ethanol extract+precipitation after water extraction and ethanol precipitation) had certain differences in the second principal component. OPLS-DA was used to compare group ① (the best pharmacological action group) and group ④ (standard decoction group). Eleven chromatographic peaks with great contribution and high reliability to group differences,were identified as gentiopicrin,skimmin,baicalin,baicalin isomer,wogonoside,5,6,7-trihydroxy-8-methoxyflavone-7-O-glucurodonaldehyde,5,6-dihydroxy-6,8,2',3'-tetramethoxyflavone,salicin-6-C-arabinose-8-C-glucoside,plantamajoside and glycyrrhizic acid. Conclusion:In the mode of pectrum-effect combination, this study explores and identifies compounds relating to the anti-inflammatory effect of QRCS decoction,so as to provide the basis for screening the extraction and purification process and optimizing the formulation of preparation of Qingre Chushi decoction.

OBJECTIVETo analyze the clinical efficacy and possible influencing factors of autologous hematopoietic Stem cell transplantation (auto-HSCT) in the treatment of patients with multiple myeloma (MM).

METHODSClinical data of 40 MM patients received auto-HSCT in the Department of Hematology of Henan Cancer Hospital from September 2010 to November 2017 were retrospectively analyzed, the clinical curative efficiency was summarized and the related factors were analyzed.

RESULTSThe curative efficiency of the patients before transplantation was 9(22.5%) with complete remission(CR), 5(12.5%) with very good partial remission(VGPR), 26(65%) with partial remission(PR), respectively, one of them was PR after 3 recurrences. The curative efficiency after transplantation was 22(55%) with complete remission(CR), 12(30%) with very good partial remission(VGPR), 6(15%) with partial remission(PR), respectively. And 2 cases were CR after double transplantation. Median follow-up time was 28.4 (3.1 to 88) months,15 cases presented disease progression, 7 cases were dead, 3-year estimated progression-free survival(PFS) and overall survival(OS) rate were 45.1% and 82% respectively. Unvariate analysis showed that the OS was affected by ISS stage (P<0.05), CR and VGPR (P<0.05) after transplantation; PFS was affected by ISS stage (P<0.01), before transplantation induction therapy (27 cases with bortezomizomi or thalidomide) (P<0.05), disease risk stratification (6 cases in high risk group) (P<0.05) , CR and VGPR (P<0.05) before transplantation, CR and VGPR (P<0.01) after transplantation. Cox multivariate regression analysis showed that the independent prognostic factors for OS were ISS stage, CR and VGPR after transplantation; the independent prognostic factors for PFS were the CR, VGPR, ISS stage after transplantation and induction therapy before transplant.

CONCLUSIONAuto-HSCT can improve the clinical efficacy and survival rate of MM patients; ISS stage, CR and VGPR after transplantation are independent prognostic factors for OS and PFS, and induction therapy before transplantation is also an independent prognostic factor for PFS.

A non-reduced SDS-PAGE purity method for quantitation of conbercept fragments was established based on gel screening, comparison of gel imaging system, linearity range of main band, screening of destaining conditions. The results indicated that the bands could be separated effectively with good clearness and flatness on 4%-15% gradient concentration gel, the peaks of all bands could be separated from baseline using high-distinguishability gel imaging system, the signal intensity of a main band had shown a good linearity with ≤ 3 μg of loading amount, and that the destaining was set as a total of ≤ 3 h with exchanging 100 mL destaining buffer every 60 min. The established non-reduced SDS-PAGE method could demonstrate the purity of conbercept more objectively. After validation, the established non-reduced SDS-PAGE method was submitted to FDA in the form of supplementary materials, which laid a quality basis for the direct entry of conbercept to the clinical Ⅲ study in the United States.

Objectives: To describe the differences between patients with angiography confirmed stent thrombosis in antiplatelet therapy and long term outcomes. Methods: We analyzed data from 1 204 patients with angiography – documented stent thrombosis between January 2008 to December 2016 in Beijing Anzhen Hospital. According to the timing of stent thrombosis post stent implantation, patients were divided into acute stent thrombosis (<24 h, n=106), subacute stent thrombosis(24 h~30 d, n=206), late stent thrombosis (>30 d~1y, n=268), and very late stent thrombosis (>1 y, n=624) groups. Death, recurrent stent thrombosis, recurrent myocardial infarction, target vessel revascularization, stroke and antiplatelet treatment during In-hospital or long-term clinical follow-up were compared among groups. Results: Prevalence of stent thrombosis was the highest in the left anterior descending artery (51.9%) in acute stent thrombosis group. Subjects with subacute stent thrombosis had a higher prevalence rate of LVEF<50% (28.2%), and subjects with very late stent thrombosis had a higher prevalence rate of diabetes (34.1%). All patients in acute stent thrombosis group received aspirin + clopidogrel, 96.5% patients in subacute stent thrombosis group and 94.5% patients in late stent thrombosis group were treated with double or triple antiplatelet therapy, while 95.2% patients in the very late stent thrombosis group were treated with double or mono antiplatelet therapy. During the follow up, mortality was 23.6%, 26.7%, 26.3% and 18.9% in acute stent thrombosis, subacute stent thrombosis, late stent thrombosis, and very late stent thrombosis groups, respectively. Conclusions: Most patients with angiography–documented stent thrombosis are treated with recommended antiplatelet therapy. Development of stent thrombosis is associated with poor outcomes.
