Potential short-term effects of tobacco control scheme under various application scenarios of tobacco control measures across the globe: a Meta-analysis / 中华流行病学杂志

Objective: based on summarizing the simulation and prediction of tobacco control measures across the globe and sorting out the various scenarios of tobacco control measures, the potential short-term effects of seven tobacco control measures in different scenarios were systematically analyzed. Methods: Until April 2022, PubMed, Embase, EconLit, PsychINFO, and CINAHL databases were used to retrieve literature about tobacco control measures simulation and prediction models across the globe. Inclusion and exclusion criteria were strictly followed. Meta-analysis for the potential short-term effects of seven tobacco control measures in different scenarios was performed using the R software. Results: A total of 22 papers covering 16 countries were selected. Five studies were conducted in the United States, three in Mexico, and two in Italy. There were all papers with the measures to tax increases, smoke-free air laws, and mass media campaigns, 21 papers with youth access restrictions, 20 with marketing restrictions, and 19 with cessation treatment programs and health warnings. The tax increases had diverse influences on the price elasticity of different age groups. The price elasticity in the age group 15-17 years was the highest, which was 0.044 (95%CI: 0.038-0.051). The potential short-term effects of smoke-free air laws in workplaces were higher than in restaurants and other indoor public places. The effects of youth access restrictions were greater in the age group <16 years than in the age group 16-17. The stronger the implementation of other measures, the greater the potential short-term effects. A comparison of seven tobacco control measures showed that the cessation treatment programs increase in cessation rate was the highest, 0.404 (95%CI: 0.357-0.456). The reduction in smoking rate and reduction in initiation rate of youth access restrictions strongly enforced and publicized was the highest in the age group <16 years, 0.292 (95%CI: 0.269-0.315), and 0.292 (95%CI: 0.270-0.316). Conclusions: The potential short-term effects of seven tobacco control measures in different scenarios were evaluated more accurately and objectively through Meta-analysis. In the short term, cessation treatment programs will substantially increase smoking cessation rates, and strong youth access enforcement will sharply reduce smoking and initiation rates among adolescents under 16. These results also offer strong data-related support for the simulation and prediction of tobacco control measures in China and other countries.

Effect of health management service for hypertension patients under framework of Basic Public Health Service Project: a regression discontinuity design / 中华流行病学杂志

Objective: To evaluate the effect of health management service on hypertension patients (HMSFHP) under the framework of the Basic Public Health Service Project by using regression discontinuity design. Methods: The participants were enrolled from an observational cohort survey in 2015 and followed up was conducted in 2019. The participants with SBP 130-150 mmHg and/or DBP 80-100 mmHg in the baseline survey of the cohort in 2015 were included in the present study. Additionally, we obtained the dates of participants receiving HMSFHP and their blood pressure data from follow-up records, physical examination records and telephone interview. The participants were divided into intervention group and control group based on the cutoff points, i.e. SBP ≥140 mmHg and/or DBP ≥90 mmHg. The local linear regression model were used to estimate the effect of HMSFHP on reducing blood pressure of the participants. Results: After adjusting for age, sex and time length of receiving HMSFHP, the results of the model including participants with 80-100 mmHg for DBP in 2015 indicated that, for the participants who received HMSFHP, the DBP decreased by 6.66 mmHg from 2015 to 2019. For the participants with SBP 130-150 mmHg in 2015, the reduction estimate of the model was -6.17 mmHg, the difference was not significant (P=0.178), suggesting that receiving HMSFHP did not cause change in SBP for the participants who received HMSFHP. Conclusion: Receiving HMSFHP had effect to reduce DBP, and HMSFHP had a positive effect on the control of blood pressure in patients with hypertension.

scRNA-seq reveals that origin recognition complex subunit 6 regulates mouse spermatogonial cell proliferation and apoptosis via activation of Wnt/β-catenin signaling / 亚洲男科学杂志(英文版)

The regulation of spermatogonial proliferation and apoptosis is of great significance for maintaining spermatogenesis. The single-cell RNA sequencing (scRNA-seq) analysis of the testis was performed to identify genes upregulated in spermatogonia. Using scRNA-seq analysis, we identified the spermatogonia upregulated gene origin recognition complex subunit 6 (Orc6), which is involved in DNA replication and cell cycle regulation; its protein expression in the human and mouse testis was detected by western blot and immunofluorescence. To explore the potential function of Orc6 in spermatogonia, the C18-4 cell line was transfected with control or Orc6 siRNA. Subsequently, 5-ethynyl-2-deoxyuridine (EdU) and terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assays, flow cytometry, and western blot were used to evaluate its effects on proliferation and apoptosis. It was revealed that ORC6 could promote proliferation and inhibit apoptosis of C18-4 cells. Bulk RNA sequencing and bioinformatics analysis indicated that Orc6 was involved in the activation of wingless/integrated (Wnt)/ β-catenin signaling. Western blot revealed that the expression of β-catenin protein and its phosphorylation (Ser675) were significantly decreased when silencing the expression of ORC6. Our findings indicated that Orc6 was upregulated in spermatogonia, whereby it regulated proliferation and apoptosis by activating Wnt/β-catenin signaling.

Effects of acupuncture in treating insomnia due to spleen-stomach disharmony syndrome and its influence on intestinal microbiome: Study protocol for a randomized controlled trial / 中西医结合学报

BACKGROUND@#Insomnia is a common complaint that is closely related to gastrointestinal symptoms, which is consistent with the traditional Chinese medicine classical theory of "stomach disharmony leading to restless sleep." Acupuncture is an effective complementary and alternative medicine therapy to improve gastrointestinal function and restore the normal sleep-wake cycle. However, studies on the effectiveness of acupuncture for insomnia due to spleen-stomach disharmony syndrome are limited to case reports and few randomized controlled trials; deeper research on its mechanism is still lacking. This randomized controlled trial aims to assess the treatment efficacy of "harmonizing stomach to tranquilize mind" acupuncture for insomnia and its influence on the intestinal microbiome.@*METHODS/DESIGN@#This is a randomized, single-blind, parallel-group study. Sixty eligible patients with insomnia due to spleen-stomach disharmony syndrome will be randomly divided into two groups (1:1 allocation ratio). The intervention group will use "harmonizing stomach to tranquilize mind" acupuncture, and the control group will receive sham acupuncture. Participants will receive 5 acupuncture treatment sessions per week for 4 consecutive weeks. The Pittsburgh Sleep Quality Index will be used to evaluate the clinical efficacy of acupuncture treatment by making assessments at baseline, the end of treatment and the end of the follow-up. High-throughput 16S ribosomal ribonucleic acid gene sequencing will be performed to detect changes in the intestinal microbial composition before and after treatment.@*DISCUSSION@#The results of this trial are expected to confirm that "harmonizing stomach to tranquilize mind" acupuncture can effectively relieve insomnia and alter the intestinal microbiome.@*TRIAL REGISTRATION@#Chinese Clinical Trials Registry: ChiCTR1800017092.

The effect of DUSP2 on proliferation and apoptosis of gastric cancer cells and its mechanism / 天津医药

@#Objective To investigate the effect of dual-specificity phosphatase-2 (DUSP2) on the cell proliferation and apoptosis in the gastric cancer and its mechanisms. Methods Firstly, the effects of different expressions of DUSP2 on the overall survival of 876 gastric cancer patients were analyzed by online analysis tool KM plotter, and the expressions of DUSP2 in various gastric cancer cell lines (MKN-45, SGC-7901, HGC-27 and N-87) were verified. Secondly, DUSP2 overexpressed lentiviral vector was constructed, and MKN-45 was transfected by packaged virus. DUSP2-overexpression gastric cancer cell line was gained by drug screening. Meanwhile, gastric cancer cells infected with empty vector virus were used as control. Then the effect of DUSP2 upregulation on the proliferation ability of gastric cancer cells was evaluated by MTS cell proliferation assay, and the apoptosis was determined by Annexin V-FITC / PI double staining. The protein expressions of DUSP2, ERK, p-ERK (Thr202/Tyr204), P38 and p-P38 were tested by the Western blot analysis. Results Gastric cancer patients with high DUSP2 expression showed a significant survival advantage compared with those with low DUSP2 expression, and DUSP2 levels were decreased in several gastric cancer cell lines. The Western blot analysis revealed that the expression of DUSP2 markedly increased in overexpressed DUSP2 group (experimental group) compared with that of control group. The MTS experiment showed that the cell viability was significantly decreased in experimental group than that of the control group. Correspondingly, the cell apoptosis test showed that the cell apoptosis rate was obviously higher in the experimental group than that of the control group. The results of Western blot assay indicated that p-ERK (Thr202/Tyr204) and p-38 were significantly down-regulated in the experimental group compared with those of control group. Conclusion The over-expression of DUSP2 can efficiently inhibit cell proliferation and promote its apoptosis in gastric cancer cells, and the mechanism is related to DUSP2 inhibiting the phosphorylation levels of ERK and P38.

Deaths attributable to alcohol use and its impact on life expectancy in China, 2013 / 中华流行病学杂志

Objective: To analyze the deaths attributable to alcohol use and its impact on people's life expectancy in China in 2013. Methods: The mortality data from the Disease Surveillance Points System and alcohol use data from China Chronic Disease Surveillance (2013) were used. The deaths attributed to alcohol use and its impact on the life expectancy of Chinese residents were estimated based on the principle of comparative risk assessment by calculating population attributable fraction. Results: In 2013, alcohol use resulted in 381 200 deaths, including 97 100 hemorrhagic stroke deaths, 88 200 liver cancer deaths, 61 400 liver cirrhosis deaths and 48 700 esophageal cancer deaths, and prevented 76 500 deaths, including 68 500, 4 900 and 3 100 deaths which might be caused by ischemic heart disease, hemorrhagic stroke and diabetes respectively. If risk factor of alcohol use is removed, the people's life expectancy would rise by an average of 0.43 years, especially in western China by 0.52 years, which was 0.12 years higher than that in eastern and central China, and the life expectancy of the population in rural and urban areas would rise by 0.48 years and 0.31 years respectively. Conclusions: Although alcohol has a protective effect on reducing ischemic heart disease, stroke and diabetes deaths, alcohol use is still a risk factor influencing the mortality and life expectancy of residents in China. It is necessary to take targeted measures to reduce the health problems caused by harmful use of alcohol.

Multi-drug resistant uropathogenic Escherichia coli and its treatment by Chinese medicine / 中国结合医学杂志

<p><b>OBJECTIVES</b>To investigate the resistance and virulence profiles of uropathogenic Escherichia coli (UPEC) and its treatment by Chinese medicine (CM) Fuzheng Qingre Lishi Formula (, FQLF).</p><p><b>METHODS</b>UPEC strains were isolated from recurrent urinary tract infections (UTIs) patients. Patient sensitivities to 17 antibiotics were tested by the disk diffusion method. Virulence genes were screened by plolymerase chain reaction. A mouse model was constructed using a multi-drug resistant and virulent UPEC strain and treated with FQLF or the antibiotic imipenem. The treatment efficacy was evaluated by bacterial clearance from urine and the urinary organs.</p><p><b>RESULTS</b>A total of 90 UPEC strains were collected, and 94.4% of the isolates were resistant to at least 1 antibiotic. Approximately 66.7% of the UPEC strains were multi-drug resistant. More than one virulence gene was found in 85.6% of the isolates. The extended-spectrum β-lactamases (ESBL)-positive strains were more resistant than the negative ones. The virulence gene number was positively correlated with the resistance number (P<0.05). A mouse model was successfully constructed using UPEC10. Treatment with either FQLF or antibiotics significantly cleared bacteria from the mouse urine after 14 days. In the untreated control, the bacteria lasted for 28 days. FQLF treatment of the UTI mouse model greatly reduced the bacterial number in the kidney and bladder, but could not completely clear the bacteria.</p><p><b>CONCLUSIONS</b>Multi-drug resistance is common among UPEC isolates, and the resistance is positively related with virulence. FQLF could treat UPEC UTIs, but could not completely clear the bacteria from the host.</p>

<p><b>OBJECTIVE</b>To observe the effect of Bushen Huoxue Recipe (BHR) on inhibiting vascular calcification (VC) in chronic renal failure (CRF) rats by regulating BMP-2/Runx2/Osterix signal pathway, and to explore its possible mechanism.</p><p><b>METHODS</b>Thirty SD rats were randomly divided into the normal group, the model group, and the BHR group, 10 in each group. Rats in the model group and the BHR group were administered with 250 mg/kg adenine suspension by gastroagavage and fed with 1.8% high phosphorus forage, once per day in the first 4 weeks, and then gastric administration of adenine suspension was changed to once per two days in the following 5-8 weeks. Rats in the BHR group were administered with BHR at the daily dose of 55 g/kg by gastrogavage in the first 8 weeks, once per day. Equal volume of normal saline was given to rats in the normal group by gastrogavage for 8 weeks. Histological changes in renal tissue and aorta VC were observed by HE staining and alizarin red staining respectively. Levels of calcium (Ca), phosphorus (P), serum creatinine (Cr), blood urea nitrogen (BUN), and intact parathyroid hormone (iPTH) in serum were detected. Protein expression levels of bone morphogenetic protein (BMP-2), Runt related transcription factor (Runx2) , and Osterix were detected by Western blot.</p><p><b>RESULTS</b>HE staining showed that compared with the normal group, disordered glomerular structure, tubular ectasia and dropsy, intracavitary inflammatory cell infiltration, dark brown crystal deposition in kidney tubules, renal interstitial fibrosis, and decreased number of renal blood vessels in the model group. Compared with the model group, normal glomerular numbers increased more, reduced degree of tubular ectasia, decreased number of inflammatory cells, and reduced adenine crystal deposition in the BHR group. Alizarin red staining showed that compared with the normal group, calcified nodes could be found in the model group, with extensive deposition of red particle in aorta. Compared with the model group, calcified nodes were reduced in the BHR group. Compared with normal group, serum levels of P, SCr, BUN, and iPTH significantly increased, serum Ca level significantly decreased, protein expressions of BMP-2, Runx2, Osterix also increased in the model group (P < 0.05, P < 0.01).
