AIM: To investigate the dynamic variety of frequency and function of FoxP3~+ regulatory T cells in patients with acute hepatitis B (AHB). METHODS: Peripheral blood mononuclear cells (PBMCs) from 15 AHB patients at acute phase (week 1 of illness), convalescent phase (primary occurrence of both ALT level normalization and HBsAg negative conversion), resolved phase (at least 8 weeks after both ALT normalization and HBsAg seroconversion, and 15 health subjects were analyzed for FoxP3 (Forkhead/winged helix transcription factor) mRNA expression in MACS magnetic beads-purified CD4~+ T cells by real-time RT-PCR assay. The effects of Treg cells on the proliferation of CD4~+CD25~- T cells were examined by a ~3[H]-thymidine incorporation assay. RESULTS: AHB patients presented a significantly higher FoxP3 mRNA expression at convalescent phase than acute phase (t=-6.04, P<0.01) and resolved phase (t=4.45, P<0.01), and healthy controls (t=3.44, P<0.01). We also observed that the suppression efficiency of Treg cells on proliferation of CD4~+CD25~- T cells was lower at acute phase than convalescent phase (t=-5.30, P<0.01) and resolved phase (t=-3.20, P<0.05), but there was no significant difference between healthy controls and any phase of AHB. CONCLUSION: AHB patients presented lower circulating Treg frequency and suppression function at acute phase, and both of them are increased at convalescent phase, and then return to normal level along with disease resolved. This follow-up study furthers our understanding of Treg' s role in immunopathogenesis of hepatitis B.

Objective To investigate the level of the clinical nurses' critical thinking disposition and the competence about nursing ethical decision making,and analyze the relationship between them.Methods A total of 359 clinical nurses were recruited by stratified random sampling method.They were investigated with general situation questionnaire,critical thinking disposition inventory-Chinese version (CTDI-CV) and judgment about nursing decisiors(JAND).Results The total score of CTDI-CV was (285.06±26.79),the total score of JAND was(267.91±16.62).The influencing factors of clinical nurses' competence about nursing ethical decision making was education background,ways of obtaining occupational knowledge,training of nursing ethical decision.The clinical nurses' competence about nursing ethical decision making was positively correlated with critical thinking disposition.Conclusions The level of clinical nurses' critical thinking disposition and competence about nursing ethical decision making are medium,in order to improve the level of competence about nursing ethical decision making,both school education and the continue education among hospital should strengthen the training of nurses' critical thinking disposition.

Objective To study the effect of sub-chronic exposure to dehamethrin(DM) on the behavior of mice in learning and memory.Methods 60 Female SPF Kunming mice were randomly divided into 4 groups and given DM by gavaging for 60 days.Morris water maze (MWM) was used to evaluate spatial memory in mice.Results After exposure to DM,the escape latency of the solvent control group and the treatment groups were (12.20±6.5)s,(14.99±5.4) s,(15.64±8.3)s,(22.71±6.2)s on the fifth day.The escape latency of the high-dose group was higher than those of the low-dose group (P=0.0041) and the solvent control group (P=0.019) in the navigation test.The number of crossing position of the platform in the high-dose group ((2.93± 1.53)times) and the middle-dose group ((3.40± 1.12) times) were lower than that in the solvent control group ((5.87 ± 1.55) times) and the low-dose group ((4.90± 1.41)times)(P＜0.05).Conclusion Sub-chronic exposure to DM can damage the spatial learning and memory of mice.

Objective To assess the effect and feasibility of group reminiscence therapy on depression in the elderly.Methods We searched the Cochrane Central Register of Controlled Trials (-2013),Medline (1982-2013),Embase (1974 2013),AMED (-2013),CINAHL(-2013),CMB (1994-2013),VIP,CNKI and Wanfang to collect the randomized controlled trials (RCTs) in which the group reminiscence therapy was used to treat depression in elderly patients.The studies were selected according to the inclusion and exclusion criteria by two reviewers,and the quality of included studies was evaluated according to Cochrane Handbook and performed meta analyses by using the Cochrane Collaboration's RevMan 5.2 software.Results A total of 10 RCTs involving 944 patients were included.The results of meta-analysis showed that as compared with conventional treatment,group reminiscence therapy on the basis of conventional treatment was more effective in decreasing depression score [MD=-4.86,95 ％ C I(-5.10,-4.65)].Compared with psychological counseling,group reminiscence therapy had more effect on decreasing depression score [MD=-9.34,95％ CI (-10.77,-7.91)].There was no significant difference in the dropout rate between group reminiscence therapy and other control treatments [RR=1.22,95％ CI (0.79-1.88)].The descriptive analysis showed that group reminiscence therapy was effective in alleviating the symptoms of depression.Conclusions Group reminiscence therapy can improve the symptoms of depression in elderly patients and conforms to the principle of economic benefit.However,the results should be interpreted with caution because of the low quality of the included studies.

Objective To explore the effects of acupoint application of midnight-noon ebb-flow with hour-prescription of points on dysfunction for sufferers with senile osteoporosis(SOP).Methods In this study,76 patients with SOP in clinic in this hospital were recruited and randomly divided into the experimental group(n=38) and the control group(n=38) in accordance with random number table.Both were on the basic treatment of Caltrate D.The experimental group performed acupoint application of midnight-noon ebb flow with hour-prescription of points,while the control one performed common acupoint application.Oswestry Disability Index(ODI) was used to evaluate the dysfunction before,after 4 weeks and 8 weeks of intervention.SF-36 was adopted to evaluate the patients' quality of life before and after 8 week's intervention.Results The ODI scores of the experimental group after 4 weeks and 8 weeks were lower than those of the control group(P＜0.01).Repeated ANOVA indicated that the scores of ODI in group effect,time effect and interaction effect were of statistical significance(P＜0.01).Further comparison showed that the scores of ODI in three different time sections suggested that the latter time point were lower than those of the former time point(P＜0.01).The scores of eight dimensions of SF-36 after the intervention of the experimental group were higher than those of the control group(P＜0.05).Conclusion The acupoint application of midnight noon ebb flow-with hour-prescription of points can effectively improve the dysfunction whose curative effect enhanced with time increasing and improve the quality of life.

Objective: To observe the joint effect of school and family tobacco control on middle school students, and to explore its effectiveness in reducing second-hand smoke exposure in middle school students’ families, as so asto provide a new way of thinking for controlling smoking among middle school sudents. Methods: A questionnaire survey was conducted on the study of 2 125 primary and high school students in four middle schools in the Dongcheng District of Beijing by means of a stratified group sampling method. Personal information of students, tobacco control environment around the family, school and surrounding ares, as well as the knowledge, attitude and behavior of students related to tobacco control was collected. Results: The exposure rate of second-hand smoke in the families of middle and high school students in Dongcheng District of Beijing was 33.41%. Smoking by at least one parent was positively correlated with second-hand smoke exposure in the student’s home (OR=22.88, P<0.05). Among the students who saw the "clear no-smoking label" on campus, the exposure rate (4.92%) when the smoking restriction was set on the home was lower than that of those who did not have a regulation in the home (58.94%) (χ2=452.57, P<0.01). The results of Logistic regression showed that there was a combination of family smoking restrictions and second-hand smoke exposure in middle and high school students who had seen the smoking ban on campus (OR=0.08) and had the school’s tobacco control education (OR=0.08). Conclusion The joint tobacco control measures between school and family can effectively reduce the exposure rate of second-hand smoke in middle school students’ families, which is better than the effect of tobacco control alone.

Objective:To evaluate the clinical efficacy and safety of combination of traditional Chinese and Western medicine in the treatment of coronavirus disease 2019 (COVID-19) by Meta analysis.Methods:The clinical randomized controlled trials (RCT) and cohort studies on the treatment of COVID-19 with combination of Chinese traditional and Western medicine published on CNKI, Wanfang database, VIP database and PubMed were searched by computer from January 2020 to June 2020. Patients in the simple Western medicine treatment group were treated with routine treatment of Western medicine, and the patients in integrated traditional Chinese and Western medicine treatment group were treated with traditional Chinese medicine on the basis of routine treatment of Western medicine. The main outcome was the total effective rate of treatment. The secondary outcome were the antipyretic rate, chest CT recovery rate, lymphocyte count (LYM), C-reactive protein (CRP) level and safety. The Cochrane manual and the Newcastle Ottawa Scale (NOS) were used to evaluate the quality of the literature; the RevMan5.3 software was used to analyze the articles that meets the quality standards, and a funnel chart was drawn to evaluate the total effective publication bias.Results:Thirteen articles were analyzed, including 1 039 COVID-19 patients, 559 in integrated traditional Chinese and Western medicine treatment group and 480 in simple Western medicine treatment group. The results of Meta-analysis showed that compared with the simple Western medicine treatment group, the combination of routine treatment of Western medicine and traditional Chinese medicine Qingfei Paidu decoction, Lianhua Qingwen granule, Shufeng jiedu capsule, Xuebijing injection or Reyanning mixture could significantly improve the total effective rate, antipyretic rate and chest CT recovery rate [total effective rate: odds ratio ( OR) = 2.95, 95% confidence interval (95% CI) was 2.10-4.14, P < 0.000 01; antipyretic rate: OR =3.01, 95% CI was 1.64-5.53, P = 0.000 4; chest CT recovery rate: OR = 2.53, 95% CI was 1.83-3.51, P = 0.000 1], increase LYM levels [mean difference ( MD) = 0.26, 95% CI was 0.02-0.50, P = 0.03], and reduce of CRP content ( MD = -17.68, 95% CI was -33.14 to -2.22, P = 0.02). Based on the funnel chart analysis of 12 articles with total efficiency, the result showed that the funnel chart distribution was not completely symmetrical, indicating that there might be publication bias. Conclusions:On the basis of routine treatment with Western medicine, combined with traditional Chinese medicine can significantly improve the total effective rate of COVID-19 and improve the laboratory results and clinical symptoms of patients. Compared with the routine treatment of Western medicine alone, the combination of traditional Chinese and Western medicine has better clinical efficacy and safety.

Objective:To investigate the clinical and genetic features of early-onset Alzheimer's disease(EOAD)and the characteristics of pathogenic mutations in probands and their families.Methods:Clinical and genetic features of three EOAD probands and their family members China were analyzed and summarized.Peripheral blood of three probands and their relatives was collected and the genes were detected by second generation sequencing(Next Generation Sequencing, NGS). Pathogenic mutations carried by the probands were identified by whole exome sequencing and then verified by Sanger sequencing in the probands and their families.Furthermore, the clinical and genetic characteristics of EOAD were discussed.Results:The first case was familial EOAD, with the heterozygous mutation c. 851C>T(p.P284L)in exon 8 of PSEN1.The second was also a case of familial EOAD, involving the heterozygous deletion mutation c. 497_499del(p.Ile167del)in exon 6 of PSEN1.In the third proband, there was no family history and the c. 626G>A(G209E)mutation was found in exon 7 of the PSEN1 gene.All three patients had memory loss as their first symptom, accompanied by clinical manifestations of slow movement, abnormal gait, unclear speech, bladder and bowel incontinence, psychiatric and other symptoms.Conclusions:These mutations represent additional mutation types and clinical manifestations in EOAD patients.Examining the genetic characteristics of PSEN1 in EOAD may contribute to the understanding of the pathogenesis, genetic classification and clinical diagnosis of EOAD.
