ABSTRACT

@#Abstract: Objective To understand the prevalence and influencing factors of major chronic diseases among Kirgiz residents in Aheqi County, Xinjiang, and to provide theoretical basis for the prevention and control of chronic diseases in this area. Methods The data of residents in Aheqi County, Kizilsu Kirgiz Autonomous Prefecture, Xinjiang in 2020 for health checkup were selected, and the permanent residents of Kirgiz nationality aged ≥18 were selected as the survey objects, and the prevalence of major chronic diseases and their influencing factors were analyzed by Logistic regression model. Results A total of 21 935 patients were enrolled, and 10 602 patients suffered from chronic diseases with a prevalence rate of 48.33%, including 4 929 cases of hypertension with a prevalence rate of 22.47%, 4 238 cases of obesity with a prevalence rate of 19.32%, 3 610 cases of dyslipidemia with a prevalence rate of 16.46%, 1 632 cases of anemia with a prevalence of 7.44%, and 1 236 cases of type 2 diabetes with a prevalence of 5.63%. The prevalence of hypertension, obesity, dyslipidemia and type 2 diabetes increased with age, while the prevalence of anemia decreased with age (P<0.01). The prevalence of hypertension dyslipidemia and type 2 diabetes was higher in males than in females, and the prevalence of obesity and anemia was higher in females than in males, with statistical significance (P<0.01). Logistic regression analysis showed that 30-<40 years old (OR=1.836, 95%CI: 1.565-2.034), 40-<50 years old (OR=2.916, 95%CI: 2.613-3.255), 50-<60 years old (OR=5.244, 95%CI: 4.651-5.913), 60 years old and above (OR=10.866, 95%CI: 9.533-12.385), government personnel (OR=1.789, 95%CI: 1.405~2.279), professional and technical personnel (OR=1.774, 95%CI:1.372-2.295), the office staff (OR=1.923, 95%CI: 1.418-2.607) occasional alcohol consumption (OR=1.157, 95%CI: 1.055-1.270) and occasional exercise (OR=1.498, 95%CI: 1.238-1.812) were risk factors for chronic disease. Conclusion The prevalence of chronic diseases among residents in Aheqi County of Xinjiang is at a low level. Local health institutions have strengthened health education and publicity on multiple chronic diseases and the prevention and control of anemia among young and middle-aged women.

ABSTRACT

The mammalian target of rapamycin (mTOR) pathway is abnormally activated in lung cancer. However, the anti-lung cancer effect of mTOR inhibitors as monotherapy is modest. Here, we identified that ginsenoside Rh2, an active component of Panax ginseng C. A. Mey., enhanced the anti-cancer effect of the mTOR inhibitor everolimus both in vitro and in vivo. Moreover, ginsenoside Rh2 alleviated the hepatic fat accumulation caused by everolimus in xenograft nude mice models. The combination of everolimus and ginsenoside Rh2 (labeled Eve-Rh2) induced caspase-independent cell death and cytoplasmic vacuolation in lung cancer cells, indicating that Eve-Rh2 prevented tumor progression by triggering paraptosis. Eve-Rh2 up-regulated the expression of c-MYC in cancer cells as well as tumor tissues. The increased c-MYC mediated the accumulation of tribbles homolog 3 (TRIB3)/P62+ aggresomes and consequently triggered paraptosis, bypassing the classical c-MYC/MAX pathway. Our study offers a potential effective and safe strategy for the treatment of lung cancer. Moreover, we have identified a new mechanism of TRIB3/P62+ aggresomes-triggered paraptosis and revealed a unique function of c-MYC.

ABSTRACT

Landfill is one of the important sources of carbon tetrachloride (CT) pollution, and it is important to understand the degradation mechanism of CT in landfill cover for better control. In this study, a simulated landfill cover system was set up, and the biotransformation mechanism of CT and the associated micro-ecology were investigated. The results showed that three stable functional zones along the depth, i.e., aerobic zone (0-15 cm), anoxic zone (15-45 cm) and anaerobic zone (> 45 cm), were generated because of long-term biological oxidation in landfill cover. There were significant differences in redox condition and microbial community structure in each zone, which provided microbial resources and favorable conditions for CT degradation. The results of biodegradation indicated that dechlorination of CT produced chloroform (CF), dichloromethane (DCM) and Cl- in anaerobic and anoxic zones. The highest concentration of dechlorination products occurred at 30 cm, which were degraded rapidly in aerobic zone. In addition, CT degradation rate was 13.2-103.6 μg/(m2·d), which decreased with the increase of landfill gas flux. The analysis of diversity sequencing revealed that Mesorhizobium, Thiobacillus and Intrasporangium were potential CT-degraders in aerobic, anaerobic and anoxic zone, respectively. Moreover, six species of dechlorination bacteria and eighteen species of methanotrophs were also responsible for anaerobic transformation of CT and aerobic degradation of CF and DCM, respectively. Interestingly, anaerobic dechlorination and aerobic transformation occurred simultaneously in the anoxic zone in landfill cover. Furthermore, analysis of degradation mechanism suggested that generation of stable anaerobic-anoxic-aerobic zone by regulation was very important for the harmless removal of full halogenated hydrocarbon in vadose zone, and the increase of anoxic zone scale enhanced their removal. These results provide theoretical guidance for the removal of chlorinated pollutants in landfills.

ABSTRACT

Objective: Coronavirus Disease 2019 (COVID-19) has been diagnosed as an epidemic disease characterized by cold and dampness pathogens in TCM clinic. Due to many Chinese medicines with different functions were used in the treatment of COVID-19, it is very important to find the law of application of damp-removing traditional Chinese medicine with high frequency application, with view to providing a reference for the use and research of Chinese medicine to further control the pandemic. Methods: The publicly released diagnosis and treatment programs issued by the National Health Commission and Health Commission of provinces, autonomous regions and municipalities, and Chinese herbs prescription information in these were collected, a database was established, and Excel and Graphpad 8.0 software were used to analyze the frequency of use of various Chinese medicines, the frequency and property characters including five flavors (bitter, pungent, sweet, sour, and salty) and four natures (warm, hot, cool, and cold) and channel tropisms of Chinese medicine for removing dampness. Results: A total of 137 prescriptions of Chinese medicine for treating COVID-19 were collected, including 178 TCMs showing functions of resolving phlegm, relieving cough and asthma, resolving dampness, clearing damp and inducing dieresis, clearing heat, tonifying deficiency, and relieving exterior syndrome, in which the TCMs with the first four functions that we called the dampness-removing TCMs, accounted for 35.78%. Also a number of TCMs in the rest functions showed removing-dampness. The first four functions were divided into subfunctions including aromatic resolving dampness, clearing heat and drying dampness, drying dampness and tonifying spleen qi, drying dampness and removing phlegm, inducing diuresis and relieving swelling, inducing diuresis and relieving exterior syndrome. Among them, the most frequently used TCMs was Ephedrae Herba, followed by Citri Reticulatae Pericarpium, Pogostemonis Herba, Pinelliae Rhizoma, Poria, Scutellariae Radix, and Atractylodis Rhizoma. The property character analysis in the dampness-removing TCMs showed that bitter and pungent were largely present and sour and astringent were absent, warm and hot were dominant; And the lung, spleen, stomach, large intestine, bladder were main channel tropisms. Conclusion: Dampness-removing TCMs are the first important type of traditional Chinese medicine to be considered in the treatment of COVID-19 in Chinese medicine. The application of dampness-removing TCMs in the treatment of COVID-19 needs to be combined with its application law. This study may provide meaningful and useful information on further research to investigate the effective compounds from the dampness-removing Chinese medicine with high frequency application, and also provide a reference for the clinical treatment of COVID-19 accurately against dampness evil with dampness-removing traditional Chinese medicines.

ABSTRACT

Objective: To explore the diagnostic value of fragmented QRS (fQRS) for coronary atherosclerotic heart disease (CHD), and to analyze it's relationship with left ventricular remodeling. Methods: From Nov. 2016 to Oct. 2018, 498 hospitalized patients in the Department of Cardiovascular Medicine of Shanghai Ninth People's Hospital, Shanghai Jiao Tong University School of Medicine were selected consecutively. During the hospitalization, all the patients underwent coronary angiography. According to the angiographic results, the patients were divided into the control group (203 patients with negative or coronary stenosis < 30%), the mild to moderate stenosis group (155 patients with coronary stenosis 30% to 75%), and the severe stenosis group (140 patients with coronary stenosis≥75%). The incidences of fQRS(+) in the normal electrocardiogram among the three groups were compared by chi-square test of R×C contingency table. Two hundred and thirty patients with single-vessel stenosis≥30% were divided into the anterior descending branch group (128 cases), the right coronary branch group (59 cases), and the circumflex branch group (43 cases), and the relationship between fQRS(+) leads and diseased vessels was analyzed by nonparametric test. Finally, all the patients were divided into fQRS(+) group (86 cases) and fQRS(-) group (412 cases). The correlation between fQRS and left ventricular ejection fraction (LVEF), left ventricular end-diastolic volume (LVEDV), left ventricular end-systolic volume (LVESV), interventricular septum thickness (IVST) and left ventricular posterior wall thickness (LVPWT), respectively, were analyzed by binary Logistic regression model. Results: The chi-square test of R×C contingency table showed that the incidences of fQRS(+) in the three groups were 8.89%, 16.13% and 30.71%, respectively, with statistically significant differences (all P < 0.05). The nonparametric test showed that the fQRS(+) leads reflecting the anterior wall (V3, V4) were more common in the anterior descending branch group, and the fQRS(+) leads reflecting the interior wall and right ventricular (Ⅱ, III, AVF, V1, V2) were more common in the right coronary branch group, the fQRS(+) leads reflecting upper lateral wall (, AVL) were more common in the circumflex branch group, with statistically significant differences (all P<0.05). Binary Logistic regression analysis showed that fQRS was negatively correlated with LVEF (r=-0.030, OR=0.971, 95% CI 0.945-0.997, P=0.029), and positively correlated with LVESV (r=0.042, OR=1.043, 95% CI 1.005-1.082, P=0.026). Conclusion: fQRS has certain reference value in the clinical diagnosis of CHD, and left ventricular remodeling may be one of the mechanisms of fQRS.

ABSTRACT

This review summarised and compared the contents and methods of America,s Health Rankings (AHR)and the County Health Rankings(CHR)in the United States by using literature review.AHR and CHR are the currently widely used population health assessment index ranking systems in the United States,respectively,which provided an analysis of population health on a state-by-state basis and a county-by-county basis by evaluating a histori-cal and comprehensive set of health outcomes and health determinants data to determine the health benchmarks and state/county rankings.The selection criteria of each indicator take into account of reliability, availability, stability, and intervention.The determination of weights of each indicator took into considerations the literature review,a histori-cal perspective,weights used by other rankings,internal analyses of the variation in outcomes explained by each factor, and pragmatic issues involving communications and stakeholder engagement.By comparison, it was found that AHR and CHR have a higher level of accuracy in the classification as they are well -defined by population demographics and geography respectively.The evaluation of health cities and health villages and towns in China is more complicated. There are few studies on village and town health rankings systems.This article reviewed the evaluation methods of AHR and CHR with a view to providing a reference for research on the evaluation system of City Health Rankings and the Village and Town Health Rankings in China.

ABSTRACT

ObjectiveTo study the effects of intermittent subglottic secretion drainage(SSD)with an endotracheal tube on incidience of ventilator- associated pneumonia(VAP). MethodsWe searched computerized databases,including Cochrane library,Pubmed,EMbase,CBM,CNKI,Wanfang and some relevant databases from initializing to March 2012,extracting data about subglottic secretion drainage(SSD)with an endotracheal tube on incidence of VAP using RCT.The data had Meta- analysis by software RevMan5,and to those data which could not be conversed or merged,they underwent descriptive analysis. ResultsWeidentifled 5 randomized clinical trials that met the inclusion criteria with a total of 683 randomized patients.In Meta- analysis,the overall risk ratio for ventilator- associated pneumonia was decreased significantly by intermittent subglottic secretion drainage with an endotracheal tube.There was no significant difference on adverse events or on hospital or intensive care unit mortality.Databases,including ICU and hospital LOS,duration of endotracheal catheterization,bacteria concentration,which were difficult to be conversed and obtained full data,they underwent a descriptive research. ConclusionsCompared with the common endotracheal tubes,the use of endotracheal tubes with subglottic secretion drainage is effective for prevention of ventilatorassociated pneumonia.But it has no effect on adverse events or on hospital or intensive care unit mortality.So large sample RCTs with multiply- center should be carried out to assess the effect of the use of SSD.

ABSTRACT

In post-marketing study of traditional Chinese medicine (TCM), pharmacoeconomic evaluation has an important applied significance. However, the economic literatures of TCM have been unable to fully and accurately reflect the unique overall outcomes of treatment with TCM. For the special nature of TCM itself, we recommend that Markov model could be introduced into post-marketing pharmacoeconomic evaluation of TCM, and also explore the feasibility of model application. Markov model can extrapolate the study time horizon, suit with effectiveness indicators of TCM, and provide measurable comprehensive outcome. In addition, Markov model can promote the development of TCM quality of life scale and the methodology of post-marketing pharmacoeconomic evaluation.

ABSTRACT

Hepatitis E, an acute infectious disease transmitted via the fecal-oral route, is caused by hepatitis E virus. However, no effective treatment currently exists for hepatitis E, and the only epidemic control approach is vaccination. But so for there are no commercial vaccine for hepatitis E available in the world. To find a new expression system to develop recombinant hepatitis E vaccine, in this study the expression system of methylotrophic yeast Hansenula polymorpha was used to express the gene encoding amino acid 112 - 607 of the open reading frame 2 (ORF2) of hepatitis E virus (HEV) genotype IV. In order to achieve high expression level, the coding sequence was optimized according to codon usage bias of Hansenula polymorpha and synthesized through overlapping PCR. Subsequently the gene was subcloned into the multi-copy expression vectors of Hansenula polymorpha, which include pDGXHP1.0 (MOX promotor), pDGXHP2.0 (MOX promotor) and pDGXHP2.1 ( FMD promotor). The series of one-copy and multi-copy recombinant plasmids were transformed into ATCC26012(Ura3-) by electroporation. The transformants were cultured in selection media MDL and screened for the existence of foreign gene by PCR. Then the strains were induced in MM media and the expression products were detected by SDS-PAGE, ELISA and Western blot assays to select the high-level expression strains. The result of SDS-PAGE showed that the HEV ORF2 expression product was accumulated up to 12% of total cellular protein and its molecular weight is 56kD. The expression product showed high immunoreactivity detected by ELISA and the highest titer is 1:2048. The result of Western blot demonstrated that the expression product could be specifically recognized by the polyclonal antibody against HEV. The successful expression of HEV ORF2 protein in Hansenula polymorpha provides foundation for the further development of recombinant subunit vaccine against hepatitis E.

ABSTRACT

<p><b>OBJECTIVE</b>To study the efficacy of hepatitis B immunoglobulin (HBIG) combining hepatitis B vaccine in high risk infants born to HBsAg positive mothers through a follow-up study program.</p><p><b>METHODS</b>184 infants (4 twin pairs) born to HBsAg carrier mothers who were consecutively recruited from December 2002 to August 2004 were followed. Major HBV serologic markers in all infants were detected by enzyme-linked immunosorbent assay (ELISA) when they were at birth, at 7th, at 24th and at 36th months.</p><p><b>RESULTS</b>7 of the 184 infants were HBsAg positive at birth, making the transplacental intrauterine infection rate of HBV as 3.80% (7/184). 125 infants were followed up at 7th months and 108 infants were followed up at 24th and 36th months. Only 2 of the 7 infants born to HBsAg-positive and HBeAg-positive mothers were persistently sera positive for HBsAg, making the chronic infection rate of HBV as 28.57%. The other 140 infants were HBsAg negative during t he follow-up period. The rate o f detectable anti-HBs i ninfants was 7.02% at birth. After infants were immunized by HBIG combining hepatitis B vaccine, the anti-HBs-positive rate reached 92% at 7th months, and gradually descended thereafter. 72.04% of the infants at 24th and 60% at 36th months showed detectable levels of anti-HBs. There was significant correlation between the produce of anti-HBs in infants and HBsAg-positive at birth while HBsAg-positive and HBeAg-positive in mothers did not relate to the produce of anti-HBs in their infants. Of 39 infants born to HBsAg-positive and HBeAg-positive mothers, 25 showed detectable levels of HBeAg. During the follow-up peirod, HBeAg was still detectable in 2 infants who were also HBsAg positive and the others all became HBeAg-negative but no infant became HBeAg-positive.</p><p><b>CONCLUSION</b>The efficacy of HBIG combining hepatitis B vaccine in high risk infants was fine.</p>
