Objective: To understand the survival status and influencing factors of HIV/AIDS patients with highly active antiretroviral therapy ( HAART ) among drug users in Yili Prefecture, Xinjiang from 2005 to 2019, so as to provide references for reducing AIDS mortality. Methods : The demographic information, clinical stage, baseline CD4+T lymphocyte ( CD4 ) level and treatment status of HIV/AIDS patients with HAART in Yili Prefecture from 2005 to 2019 were collected through AIDS Antiretroviral Therapy Information System. The survival rate was calculated by the life table method. The influencing factors for survival time were analyzed by Cox proportional hazard regression model. Results: Totally 1 935 patients were recruited, the median age receiving HAART was 37 years old and the median CD4 counts was 293/μL. The cumulative survival rates at 1, 5, 7 and 10 years were 97%, 78%, 73%, and 66%, respectively. The multivariate Cox proportional hazards regression analysis showed that the patients with body mass index of 18.5-<28.0 kg/m2 ( HR: 0.391-0.656, 95%CI: 0.234-0.958 ), baseline CD4>200/μL ( HR: 0.354-0.667, 95%CI: 0.232-0.841 ) , or missed medication in the last 7 days ( HR=0.009, 95%CI: 0.001-0.061 ) had lower risk of death; the patients with WHO clinical stage of Ⅱ-Ⅳ ( HR: 1.479-2.311, 95%CI: 1.004-3.288 ) or treatment delay ≥1 years ( HR: 1.287-1.388, 95%CI: 1.029-1.826 ) had higher risk of death. Conclusions The 5-year cumulative survival rate of HIV/AIDS patients with HAART in Yili Prefecture is 78%. Body mass index, baseline CD4 level, WHO clinical stage, treatment delay and missed medication in last 7 days were the influencing factors for survival time.

This article introduces the principle, structure and components of a visualization system for carrying out minimally invasive surgical abortion. Without altering the current surgical approach or increasing the surgical difficulty, the surgical system integrated a mini-CMOS image sensor and LED light and a visual device to allow fixed-point removal of the fetus or embryo in the minimally invasive surgery.

An immunopotentiating compound has been isolated from the metabolites of Bacillus mycoides under the bioassay-guided isolation and identification for its immunopotentiating effect and chemical structure. The isolation and purification of the compound were consisted of macroporous adsorptive resins, silicagel chromatographic column and Sephadex G-200 chromatographic column. The immunopotentiating effect was assayed in every step isolation. At last, the only substance having the strongest immunopotentiating effect had been isolated and purified. Through the procedure consisiting of Ultra-Violet spectroscopy (UV), IR (Infrared Radiation), Time of Flight Mass Spectrum (TOF-MS), Nuclear Magnetic Resonance (NMR) and Element analysis, the possible structure of compound M had been identified as cyclic (Pro-Gly) dipeptide (C7H10O2N2) (Diketopiperazine). To be determined the immunopotentiating effect, the mice were treated by intraperitoneal injection of cyclic (Pro-Gly) dipeptide in the treatment group and physiologic saline in the control group. At the 14th day after the injection, the SOD activity and the phagocytosis activities reached the peak value and were significantly higher than those in control group. At the 21st day, the bactericidal activity reached peak value and was significantly higher than that in the control group. From the above results, we concluded that the main active component enhancing the immunity of mice was cyclic (Pro-Gly) dipeptide in the metabolism of Bacillus mycoides.

Objective:Preparation and immune characteristic analysis of polyclonal antibody against hypervariable region protein of Taura syndrome virus major capsid protein VP 1 as a reference for studies on immunological diagnosis reagent.Methods:The recombinant vector pET-VP1 was transformed into E.coli BL21 for protein expression.Immunizing a New Zealand rabbit with purified VP1 protein,the titer of anti-VP1 serum was determined by Agar diffusion test and ELISA.Monoclonal phage specific binding to the purified VP1 protein was used for competitive inhibition test.Results: The VP1 protein was soluble and high expression in E.coli BL21.The biological activity titer of anti-VP1 serum reached 1∶26 ,1∶217 determined by Agar diffusion test and ELISA respectively.A litter binding activity of antiserum and VP 1 protein could be blocked by monoclonal phage , but would not affect the final positive result.Conclusion:High titer antibody Preparation of the VP 1 hypervariable region protein.The binding activity of the polyclonal antibody with VP1 protein was not affected by the mutations of VP 1 protein in minority areas ,so the antiserum could be used as immu-nological detection diagnosis agent.

Cocrystal separation technology is a technology that utilizes coformers to selectively form cocrystals with target compounds and separate them from mixed systems. Our study used puerarin (PUE), daidzein (DDZ), and genistein (GEN) as model drugs, which have similar structures and are the main isoflavones in Pueraria lobata root. The separation and purification processes in the modern traditional Chinese medicine (TCM) of these three components use conventional column chromatography, recrystallization, and other technologies, which have the issues of lengthy separation cycles, high solvent consumption, and inefficient preparation. Different with existing separation technology, our team used the early-found cocrystal separation method to design a step-by-step extraction and separation experiment of GEN-PUE-DDZ ternary mixture. Caffeine and L-proline were added to the mixed system in turn, GEN-caffeine cocrystal and PUE-proline cocrystal were prepared by suspension method. The cocrystals precipitated out of the solution. The purities of the GEN-caffeine cocrystal and the PUE-proline cocrystal could achieve 93% (the purity of GEN) and 99% (the purity of PUE). Besides, the purity of DDZ could also be increased by 6.76 times. This study proposed a simple operating, low cost and wide application range separation method different from the traditional separation method and realized the separation of structurally similar chemical components in TCM, laying a foundation for the application of cocrystal technology in the separation and refining of TCM.

Objective To determine the status of false-positive report of congenital syphilis (CS),to analyze the possible causes of mis-diagnosis.Methods Basic information on CS in Shanghai in the past five years was collected.We identified infants diagnosed with CS and followed up the sero- logical reactivity of those patients and their mothers.The serological reactivity[rapid plasmin reagin (RPR)and treponema palidum hemagglutination assay(TPPA)]of infants was followed-up for up to 24 months,or until both antibodies turned to negative.The medical history of the mothers was col- lected,and their sera were examined for syphilitic antibodies.Results Total 99 infants diagnosed with CS were recruited. The major diagnostic method was treponemal antibody detection.Only 31.3% of the 99 infants exhibited clinical symptoms or syphilis-like symptoms at delivery.The cumu- lative RPR loss rates of the infants were 44.2%,64.0%,72.7%,83.9% and 87.1% at 1-3,3-6,6- 12,12-18 and 18-24 months after birth,respectively.The cumulative TPPA loss rates were 1.1%, 18.6%,44.6%,66.7% and 74.4% for 1-3,3-6,6-12,12-18 and 18-24 months after birth,respec- tively.TPPA remained positive in all mothers with syphilis.Conclusion The diagnosis of congenital syphilis determined solely by the positive tests of RPR and TPPA is unreliable and can be misdiagno- sis.The diagnosis and management of congenital syphilis should be urgently improved,and that the profes- sional health institutions should perform and closely monitor the quality controls in the diagnosis of CS and standardize the intervention strategy of maternal syphilis.

Genes related to trehalose biosynthesis from a bacterial strain Micrococcus luteus which can convert partially hydrolyzed starch into trehalose were cloned.Full sequence of gene (MtreY) encoding trehalose maltooligosyl trehalose synthase (MTSase) and partial sequence of gene (MtreZ) encoding maltooligosyl trehalose trehalohydrolase (MTHase) were got using PCR combined non-random shotgun method.Sequence analysis of MtreY predicts a 2370bp open reading frame encoding a protein of 790 amino acids with a predicted molecular weight of 86734 Da.Homologous analysis shows that this new gene has the same conservative motifs with ?-amylase family enzymes.The MtreY gene was expressed in E.coli, and the expression product has the anticipative enzyme activity.
