Background The worldwide COVID-19 pandemic has turned into a global catastrophic public health crisis, and the conclusion about the risk factors of hospital death in COVID-19 patients is not uniform. Objective To explore risk factors of in-hospital death in patients with COVID-19 by a meta-analysis. Methods Case-control studies about risk factors of in-hospital death in COVID-19 patients were searched from databases of the Cochrane Library, ScienceDirect, PubMed, Medline, Wanfang Data, CNKI and CQVIP from inception to October 1, 2021. Literature screening, data extraction and methodological quality assessment were conducted. Meta-analysis was performed using Stata 15.1. Meta-regression was used to explore the potential sources of heterogeneity. Results Eighty studies were included which involving 405 157 cases〔349 923 were survivors (86.37%) , and 55 234 deaths (13.63%) 〕, that were rated as being of high quality by the Newcastle-Ottawa Scale. Meta-analysis showed that being male〔OR=1.49, 95%CI (1.41, 1.57) , P

A thorough re-evaluation of all extant literature, as well as documents and archaeological relics unearthed since the 1960s, confirms that acupuncture is not as ancient as has generally been assumed, and that it did not, in fact, appear and gradually develop during China's Neolithic Age (c. 8000-3500 BCE). Rather, this great invention arose quite suddenly, and rapidly developed, approximately two millennia ago. [ABSTRACT FROM AUTHOR]

Background: Chronic heart failure (CHF) is a complex cardiovascular disorder resulting from prolonged heart disease, leading to structural and functional damage, weakened myocardial contraction, and inadequate cardiac output for daily metabolism. The purpose of study is accurate evaluation and early identification of cardiac function and ventricular remodeling through effective biochemical indicators., Methods: This study, conducted from April 2020 to March 2021, included 100 CHF patients meeting the Chinese Guidelines for the Diagnosis and Treatment of Heart Failure 2020 from First People's Hospital of Linping District, ascertaining a confirmed diagnosis based on these established guidelines. The objective of detecting these biomarkers is not for early diagnosis, given that the subjects are already diagnosed according to the guidelines. Instead, our focus is on using these biomarkers to assess disease severity, prognosis, or treatment response in the context of diagnosed CHF patients. Classification comprised 42 ischemic and 58 non-ischemic CHF cases, with NYHA cardiac function grading (I, II, III-IV) and left ventricular ejection fraction (LVEF) categorization (≤ 40%, >40%). A control group of 100 healthy volunteers was selected for comparison. SuPAR, APN, and IgE expressions were analyzed among different groups and LVEF categories. Diagnostic efficacy was assessed through ROC curves, and correlations with cardiac function and LVEF were explored., Results: SuPAR, APN, and IgE expressions were significantly higher in CHF patients compared to the control group. Increasing cardiac function grades in CHF patients correlated with a gradual elevation in suPAR, APN, and IgE expressions. Comparing LVEF groups, CHF patients with LVEF ≤ 40% exhibited significantly higher suPAR, APN, and IgE expressions. Combined detection of suPAR, APN, and IgE demonstrated superior diagnostic accuracy (AUC of 0.899) compared to individual markers. Positive correlations were observed between suPAR, APN, IgE, and cardiac function grades, while LVEF showed a significant negative correlation with these biomarkers., Conclusions: SuPAR, APN, and IgE expressions are elevated in CHF patients, and their combined detection serves as a highly efficient auxiliary diagnostic method. The findings offer valuable insights into the diagnosis and treatment of CHF patients.

We aimed to study the association between the non-coding region of the lncRNA MALAT1 gene, the non-coding region rs664589 C>G variant, and the risk of acute myocardial infarction (AMI) in the Chinese Han population. 165 NSTEMI and 135 STEMI patients were enrolled in the study. An additional 150 healthy individuals were enrolled as the controls. All subjects were analyzed for the MALAT1 rs664589 locus genotype. The receiver operating curve (ROC) was used to determine the effect of MALAT1 rs664589 single nucleotide polymorphism (SNP) on the diagnosis of AMI by plasma lncRNA MALAT1. The MALAT1 rs664589 site G allele carrier was 1.39 times more likely to have NSTEMI than the C allele carrier (95% CI: 1.16-1.61, P = 0.001) and 1.59 times more likely to have STEMI than the C allele carrier (95% CI: 1.31-1.85, P < 0.001). The MALAT1 rs664589 site C>G mutation resulted in an increase in the area under the ROC curve (AUC) of the plasma lncRNA MALAT1 level for the diagnosis of AMI. The plasma lncRNA MALAT1 levels in AMI patients were negatively correlated with hsa-miR-1972, hsa-miR-194-5p, hsa-miR-4717-5p, hsa-miR-6735-3p, and hsa-miR-3677-5p (r = -0.81, -0.75, -0.66, -0.71, and -0.88). The C>G mutation of MAL6641 rs664589 causes an increased risk of AMI in the Chinese Han population. The SNP at this site affects the value of plasma lncRNA MALAT1 in the diagnosis of AMI. The specific mechanism may indicate that the C>G mutation of the MALAT1 rs664589 changes the regulation of miRNAs expression by lncRNA MALAT1.

India and China are both featured with ancient civilization. During the communication between the two countries, the communication from Indian culture, especially Buddhism, to China was predominant, while communication from Chinese culture to India was rare. So it was with medical communication until the end of 1950s when acupuncture was introduced to India. In this article, the medical communication between India and China as well as the introduction of acupuncture to India were discussed, and the resulting phenomenon was analyzed. The introduction of acupuncture to India proved personnel exchange was not necessary to acupuncture communication, and several invisible factors, such as language, religion and culture tradition might be the reasons for foreign nations to accept acupuncture. Therefore, these factors should be valued in the future international communication of acupuncture.

Iran is the neighbor of western China, and is a key transport junction on ancient Silk Road. The medical communication between China and Iran dates back to the 10th century, however, according to current evidences, it is indicated that acupuncture has not been introduced to Iran until the early 1970s. Unfortunately over the last 40 years, the acupuncture in Iran has not presented great development. The history of acupuncture development in Iran implies that geographical advantage and personnel exchanges are not essential to the international exchange of acupuncture, while language and cultural background may hinder the spread of acupuncture in foreign countries.
