Objective To study the therapeutic effect of Danshen injection combined with conventional therapy on children with recurrent asthmatic bronchitis. Methods A prospective study was conducted. Fifty-five children with asthmatic bronchitis admitted in People's Hospital of Henan Province from January 2012 to July 2014 were enrolled and randomly divided into a integrative Chinese and western medicine group(30 cases)and a conventional therapy group(25 cases);in the same period,18 healthy children having passed physical examinations were chosen as the healthy control group. In the conventional therapy group,rest,oxygen inspiration,anti-infection, fluid supplement and aerosol inhalation,etc. were given,while in the integrative Chinese and western medicine group,based on the similar conventional therapies,additionally Danshen injection 0.4 mL · kg-1 · d-1 was given,once per day for a total of 14 days. The wheezing remission time and the pulmonary rale extinction time were observed in the two patient groups,and the fractional exhaled nitric oxide(FeNO)content was investigated in the three groups. Results The wheezing remission time and the pulmonary rale extinction time of the integrative Chinese and western medicine group were obviously shortened compared with those in the conventional therapy group〔the wheezing remission time(days):2.3±0.8 vs. 5.2±1.1,the pulmonary rale extinction time(days):6.8±1.5 vs. 8.4±1.1,both P<0.01〕. The contents of FeNO in the integrative Chinese and western medicine group and the conventional therapy group before treatment were significantly higher than those in the healthy control group(×10-9:30.3±9.5,30.4±8.2 vs. 13.6±3.4,both P<0.01),but after treatment the FeNO levels of both patient groups were markedly lowered,and the degree of change in integrative Chinese and western medicine group was more significant(×10-9:18.6±4.7 vs. 24.0±6.8,P<0.01). Conclusion Danshen injection combined with conventional therapy can obviously down-regulate the FeNO content,alleviate the airway inflammation,effectively relieve the children recurrence of asthmatic bronchitis.

Objective To identify and rename one strain stored in National Center for Medicine Culture Collections ( CMCC) and used for tracheitis vaccine production. Methods The test strain CMCC (B)29108 and the type strain DSM30007T were cultured on NA medium. Characteristics in morphology, physiology, biochemistry and fatty acid profile were compared between the two strains. Phylogenetic analysis was based on 16S rRNA and rpoB gene sequences, together with the DNA-DNA hybridization assay. Results A Comparative analysis of a partial sequence of the 16S rRNA gene sequence revealed that the CMCC( B) 29108 strain was closed to the Acinetobacter species and showed the highest similarity with the type strain Acinetobacter baumannii DSM30007T. Moreover, the CMCC(B)29108 strain was highly similar to type strain DSM30007T in morphology, physiology, biochemistry and fatty acid profile. On the phylogenetic tree based on 16S rRNA and rpoB gene of all Acinetobacter members, the CMCC(B)29108 strain steadily clustered into one independent branch only with the DSM30007 T strain with a DNA-DNA hybridization value of 100%. Conclusion The CMCC(B)29108 strain that is one of the strains used for the production of tracheitis vac-cine should be assigned to the species of Acinetobacter baumannii based on its phenotypic, phylogenetic and chemotaxonomic characteristics.

Objective To explore the impact of broad antigen HLA-Bw4 on disease progression in HIV-1 infected subjects. Methods Three hundred and forty subjects chronically infected with HIV-1 and 69 HIV-1 negative subjects were recruited and HLA-B alleles were typed with sequence-based high resolution typing assay. HLA-Bw genotypes of these HIV-1 infected subjects were determined and their association with CD4+ T cell counts and viral loads were analyzed. Results Sixty-five HLA-B alleles were detected in HIV-1 positive subjects. Subjects with Bw4 (Bw4 homozygotes and Bw4Bw6 heterozygotes ) had higher CD4+ T cell counts ( P = 0. 004 ) and lower plasma viral load ( P = 0.003 ) than subjects without Bw4 ( Bw6 homozygotes). When compared with HIV-1 postive subjects with CD4+ T cell counts above 500 celis/μl, those with CD4+ T cell counts below 500 cells/μl were observed with decreased percentage of Bw4Bw6 heterozygote ( P =0.0002) and increased percentage of Bw6 homozygotes ( P < 0. 0001 ). There is no significant difference in CD4+ T cell counts between Bw4 homozygotes and Bw4Bw6 heterozygote, but lower viral loads were observed in Bw4Bw6 heterozygotes( P = 0. 037 ). Conclusion HLA-Bw4 can confer pretective effects on H1V-1 infected subjects by maintaining higher CD4+ T cell counts and lower viral load, the mechanism behind this effect need further exploration.

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.

Objective:To investigate the consistency of reports of adverse reactions to chemotherapy in patients with stomach neoplasms, main caregivers and nursing records.Methods:By convenient sampling method, a total of 102 pairs of patients who underwent radical gastrectomy and received chemotherapy in the First Affiliated Hospital of Zhengzhou University from June 2018 to June 2019 and their main caregivers were selected. After the second and fourth cycles of chemotherapy, the incidence of adverse reactions to chemotherapy in patients was collected from records patients themselves, main caregivers and nursing staff, and the severity of adverse reactions was assessed using the Chinese version of M.D. Anderson Symptom Inventory (MDASI) . At the same time, Kappa test was used to analyze the consistency of reports of patients, their main caregivers and nursing staff to the 13 adverse reactions of chemotherapy in the scale.Results:After the second chemotherapy cycle, except for the two adverse reactions of fatigue and distress, the severity of other adverse reactions reported by the patients was not statistically significantly different compared with the records of the main caregivers and nursing staff ( P>0.05) . The incidence of fatigue, distress, sleep disturbance, nausea and dry mouth reported by the patients was higher than that recorded by the primary caregivers and nursing staff, and the differences were statistically significant ( P<0.05) . The patients showed good consistency with main caregivers in 10 aspects such as appetite loss, shortness of breath, sleep disturbance, vomiting, pain, nausea, dry mouth, drowsiness, forgetfulness and numbness ( P<0.05) . The patients showed good consistency with the nursing staff in 9 aspects such as appetite loss, shortness of breath, vomiting, pain, nausea, dry mouth, lethargy, forgetfulness and numbness ( P<0.05) . The main caregivers showed good consistency with the nursing staff in 10 aspects such as appetite loss, distress, shortness of breath, vomiting, pain, nausea, dry mouth, lethargy, forgetfulness and numbness ( P<0.05) . After the fourth chemotherapy cycle, the self-reported severities of fatigue, distress, sleep disturbance and sadness of patients were higher than those recorded by the main caregivers and nursing staff, and the differences were statistically significant ( P<0.05) . The incidence of fatigue, distress, sleep disturbance, sadness and dry mouth reported by patients were higher than those recorded by the main caregivers and nursing staff, and the differences were statistically significant ( P<0.05) . The patients showed good consistency with the primary caregivers in 8 aspects such as appetite loss, shortness of breath, vomiting, pain, nausea, dry mouth, forgetfulness and numbness ( P<0.05) , and they showed good consistency with the nursing staff in 7 aspects such as appetite loss, vomiting, pain, nausea, dry mouth, forgetfulness and numbness ( P<0.05) . The primary caregivers showed good consistency with the caregivers in 8 aspects such as appetite loss, sleep disturbance, vomiting, pain, nausea, dry mouth, forgetfulness and numbness ( P<0.05) . Conclusions:Nursing staff and the main caregivers of patients underestimate the incidence and severity of chemotherapy-related adverse reactions in patients with stomach neoplasms. Simple nursing records cannot accurately reflect the patients' chemotherapy symptoms, so self-reports of patients should be considered as one of the reference data.

Objective:To understand influencing factors on the deaths of HIV/AIDS patients receiving antireviral treatment in Butuo county of Liangshan Yi Autonomous Prefecture (Liangshan) from 2010 to 2019, to provide data for drug replacement and sustainable antiviral treatment strategy.Methods:A matched case-control study was used to collect basic and follow-up information on AIDS death patients receiving antiviral treatment in Butuo county of Liangshan from 2010 to 2019. The control group was formed by sampling twice the number of cases. The logistic regression model was used to analyze the risk factors affecting mortality.Results:In 3 355 patients of HIV/AIDS treated with antiviral therapy, 1 179 cases in the death group and 2 176 cases in the control group. Including 81.34% were 30-49 years old, 69.09%males, 99.55% Yi nationality, 91.12% were married or cohabitated, 95.77% had junior high school education or below, and 88.41% peasants. Amultivariate logistic stepwise regression model showed that among the death risk factors, age ≥50 years old was 5.08 times (95% CI:3.05-8.48) that of the 18-29, female was 0.70 times (95% CI: 0.52-0.94) than male, the transmission rate of intravenous drug use was 1.43 times (95% CI: 1.06-1.91) that of heterosexual transmission, CD4 +T lymphocyte (CD4) count ≥350 cells/μl before treatment was 0.38 times (95% CI: 0.30-0.48) that of CD4 <200 cells/μl before treatment, the most recent antiviral treatment regimen containing LPV/r was 0.04 times (95% CI: 0.01-0.18) than that of stavudine (d4T) + lamivudine (3TC) + nevirapine (NVP)/efavirenz (EFV) regimen, drug resistance was 3.40 times (95% CI: 2.13-5.42) of non-drug resistance, non-viral load and non-drug resistance test results were 12.98 times (95% CI: 10.28-16.40) of non-drug resistance. Conclusions:Age, gender, transmission route, CD4 before treatment, the latest antiviral treatment program, and drug resistance test after antiviral therapy were the influencing factors of HIV/AIDS death in Butuo county. It is necessary to expand the coverage of viral load and drug resistance test to change the antiviral therapeutic schedule scientifically and carry out publicity and education on the compliance of patients with antiviral treatment and medical staff training in order to reduce the mortality of patients with antiviral treatment.
