Objective　To understand the impact of early and timely treatment and initial antiviral treatment regimen on mortality and attrition of antiretroviral therapy. Methods A retrospective cohort study was conducted using download data on antiretroviral therapy for HIV-infected patients in Liuzhou City, Guangxi Province, from the database of the Basic Information System for AIDS Control and Prevention (BISAC) from 2010 to 2020. The Cox proportional risk regression model was used to analyze the influencing factors of mortality and attrition. Results A total of 15 713 infected patients were included, including 53.4% aged 18-<50 years, 69.4% male, 61.0% farmer, 75.1% CD4 count <350 cells /μL before initial antiviral treatment, the overall mortality rate was 4.30/100 person-years, and the overall attrition was 2.42/100 person-years. The results of Cox regression analysis showed that the influencing factors of mortality were pretreatment CD4 counts of 350-<500 cells/μL(AHR=0.72, 95%CI: 0.63-0.81) and ≥500 cells/μL (AHR= 0.64, 95%CI: 0.55-0.76); duration from diagnosis to initial antiviral treatment 91-180 days (AHR=1.25, 95%CI: 1.08-1.45), 181-365 days (AHR=1.26, 95%CI: 1.08-1.47), and ≥365 days (AHR=1.26, 95%CI: 1.11-1.44); initial antiviral treatment regimens of D4T+3TC+EFV/NVP (AHR=1.47, 95%CI: 1.32-1.63) and AZT/D4T/TDF+3TC+LPV/r (AHR=1.73, 95%CI: 1.50-1.99). Factors affecting attrition were pretreatment CD4 counts of 350-499 cells/μL (AHR=1.32, 95%CI: 1.16-1.50) and ≥500 cells/μL (AHR=1.28, 95%CI: 1.10-1.50); interval from HIV positivity confirmation to initial dosing ≥365 days (AHR=1.21, 95%CI: 1.04-1.40), initial antiviral treatment regimens of TDF+3TC+NVP (AHR=1.32, 95%CI: 1.13-1.55), AZT+3TC+EFV/NVP (AHR=1.43, 95%CI: 1.26-1.62) and AZT/D4T/TDF+3TC+LPV/r (AHR=1.33, 95CI%: 1.06-1.67). Conclusions　Early and timely treatment and the initial antiviral treatment regimen of TDF+3TC+EFV have good efficacy, but attention should be paid to the high risk of attrition of HIV-infected people with high CD4 count before treatment.

OBJECTIVETo evaluate the clinical value of multicolor melting curve analysis(MMCA) for detecting genetic mutations in G6PD deficiency.

METHODSA total of 402 peripheral blood samples(256 males and 146 females) were collected from suspected patients or their relatives at the Prenatal Diagnosis Center of Liuzhou Maternal and Child Health Hospital between March 2012 and May 2012. The samples were screened by G6PD/6PGD quantitative ratio testing. The reliability of the assay was evaluated by multiplex probe melting curve assay(which can detect 16 G6PD mutations) and DNA sequencing through a double blind study.

RESULTSOne hundred seventy cases with G6PD/6PGD ratio < 1.0 and 232 cases with G6PD/6PGD ratio ≥ 1.0 were detected by the enzymological method. DNA sequencing has identified 182 wild type samples, 151 hemizygous mutation samples, 5 female homozygous mutation samples, 54 female heterozygous mutation samples and 10 female double heterozygous mutation samples. Multicolor melting curve analysis has detected 185 wild type samples, 148 hemizygous mutation samples, 5 female homozygous mutation samples, 55 female heterozygous mutation samples and 9 female double heterozygous mutation samples. The specificity and sensitivity of G6PD gene mutation detection by multicolor melting curve analysis were 100%(182/182) and 98.6%(217/220), respectively. The positive predictive value and negative predictive value were 99.5%(216/217) and 98.4%(182/185), respectively, and the Youden's index was 0.986. The concordance rate of the sample detection between the melting curve assay and DNA sequencing was 99.0%(398/402). Twenty-one different genotypes were detected by the multicolor melting curve analysis and 24 different genotypes were detected by DNA sequencing. Four samples containing mutations(c.196T>A or c.406C>T) were not detected by multicolor melting curve analysis, which can be attributed to different technical settings of the two methods.

CONCLUSIONMulticolor melting curve analysis for G6PD gene mutation detection is a simple, rapid, sensitive and specific method, which can be used for clinical diagnosis of G6PD deficiency.

Objective:To investigate the mortality burden among permanent residents in Shenzhen from 2014 to 2021 and to provide scientific evidence for establishing precision disease prevention and control strategy.Methods:Based on the cause-of-death surveillance data, we described the distribution of mortality rate, cause-specific rankings, and years of life lost (YLL) for the total population and subgroups in Shenzhen from 2014 to 2021. The seventh national population census data was used as the standard population to calculate the standardized mortality rate. Joinpoint log-linear regression model was used to analyze the chronic trend of mortality burden.Results:From 2014 to 2021, 49 734 deaths among the permanent population were recorded in Shenzhen, with a 140.90/100 000 average crude mortality rate, standardized as 366.77/100 000. Both the crude mortality rate and standardized mortality rate showed fluctuating increases from 2014 to 2016 [annual percent change (APC)=20.72%, P=0.048, APC=28.59%, P=0.016] and fluctuating decreases from 2016 to 2021 (APC=-1.55%, P=0.317, APC=-1.89%, P=0.190). The mortality rates of the <20 and 20- age groups decreased over time, with a statistically significant decrease observed in the <20 age group [average annual percent change (AAPC)=-11.91%, P<0.001]. The mortality rates of the 40-, 60-, and ≥80 age groups increased over time, with an increase observed in the ≥80 age group from 2014 to 2016 (APC=45.25%, P=0.016) and a decrease from 2016 to 2021 (APC=-2.18%, P=0.280). There was no statistical significance in the mortality rate trend for the remaining age groups (all P>0.05). The top three causes of death among permanent residents in Shenzhen from 2014 to 2021 were consistently malignant tumors, cardiovascular and cerebrovascular diseases, and respiratory system diseases, with crude mortality rates of 49.59/100 000, 47.95/100 000, and 7.90/100 000 respectively in 2021. From 2014 to 2021, 1 003 287.43 YLL were observed, with YLL for the total population, males and females all showing an upward trend (all P<0.001). Conclusions:The mortality burden among the elderly permanent residents in Shenzhen displayed a continuously increasing trend from 2014 to 2021. Strengthening the need for substantial efforts and actions to improve the prevention and control of chronic non-communicable diseases.

Objective To systematically review the effects of hospital-community integrated management mode in diabetes mellitus. Methods To comprehensively search the database including CNKI, Taiwan Airiti library, WanFang Data, WeiPu Data and PubMed, we manually searched the relevant references of literature for the RCTs on hospital-community integrated management mode in diabetes mellitus, and Meta-analysis was used by software Revman 5. 2, and making descriptive analysis of the outcomes which could not be merged. Results A total of 15 RCTs were included involving 3 in English and 12 in Chinese, and 7 studies with high-quality and 8 of them with low-quality. According to the 11 evaluation focused outcomes indexes, the result of Meta-analysis showed that compared with conventional management, the hospital-community integration mode could effectively improve patients′ biochemical indicators such as glycated hemoglobin (HbA1c)[MD= -0. 39, 95%CI(-0. 56, -0. 22),P<0. 001], fasting plasma glucose[MD=-0. 75, 95%CI (-1. 16, -0. 33),P<0. 001], triglycerides[MD= -0. 36, 95%CI ( -0. 63, -0. 10), P=0.007], high-density lipoprotein (HDL-C)[MD =0. 09, 95%CI (0. 04, 0. 14), P <0. 001], low density lipoprotein (LDL-C)[MD= -0. 15, 95%CI (-0. 23, -0. 06),P=0. 001], but there was no effect on total cholesterol[MD= -0. 27, 95%CI (-0. 58, 0. 03),P=0. 080]. At the same time, the descriptive analysis presented that the model could improve patients′ awareness rate of diabetes health knowledge and promote the correct behavior of medication and regular exercise, in addition it could increase the score of life quality and reduce medical expenses. Conclusions Diabetes hospital-community integrated management can effectively improve the level of blood glucose and blood lipids, reduce the occurrence and development of related complications and provide a reliable basis for the management of diabetic patients. There is a positive impact to improve the patients′ behavior and quality of life, but it requires more randomized controlled studies to be analyzed and verified.

OBJECTIVE: To explore the repair effects of bone marrow mesenchymal stem cells( BMSCs) on hematopoietic injury induced by benzene poisoning in mice. METHODS: Five specific pathogen free healthy male Kunming mice were selected to obtain BMSCs through bone marrow attachment culturing method. The Kunming mice were randomly divided into poisoning group and BMSCs transplantation group,18 mice in each group,after the benzene poisoning model was established by subcutaneous multi-point injection of benzene and oil mixture 3 times/week,10 weeks continuously. Each group was injected through tail vein with 250. 0 μL 0. 9% sodium chloride solution or 250. 0 μL BMSCs suspension( cell density 2 × 109/L) once per week for 4 weeks,respectively. The control group( 10 mice) was not given any treatment.Mice were euthanized 2 weeks after treatment. The blood routine examination was conducted. Nucleated cells in bone marrow were observed after Giemsa staining. The clones of hemopoietic progenitor cells were counted and the levels of serum interferon-γ( IFN-γ) were examined using enzyme-linked immune sorbent assay. RESULTS: The mouse model of chronic benzene poisoning was established successfully. After the BMSCs transplantation treatment,the white blood cell count,platelet count,red blood cell count,hemoglobin level and bone marrow nucleated cell as well as granulocyte-macrophage colony forming unit( CFU-GM) in benzene poisoning group were significantly decreased compared with control group( P <0. 01),while those indexes of BMSCs treatment group were higher than that of benzene poisoning group( P < 0. 05). The counts of platelet,red blood cell,bone marrow nucleated cell and CFU-GM in BMSCs treatment group were significantly lower than that of control group( P < 0. 05). The level of serum IFN-γ in benzene poisoning group was higher than that of control group( P < 0. 01),and serum IFN-γ level in BMSCs treatment group was lower than that of benzene poisoning group( P < 0. 01). There was no significant difference of IFN-γ level in BMSCs treatment group compared with control group( P > 0. 05). CONCLUSION: BMSCs have repair effects on hematopoietic system injury caused by benzene poisoning.
