ABSTRACT

Nonalcoholic fatty liver disease (NAFLD) has gradually become the main reason affecting human liver health, and many factors are involved in the development and progression of NAFLD. Mitochondria, as the “energy factory” of cells, plays an important role in maintaining normal physiological functions. Studies have shown that hepatic mitochondrial dysfunction promotes the development and progression of NAFLD. This article briefly introduces the latest research advances in the basic characteristics and physiological function of liver mitochondria and reviews new research findings in the association of mitochondrial dysfunction with obesity, simple fatty liver disease, and nonalcoholic steatohepatitis, in order to provide new ideas for the research on targeted mitochondrial therapy for NAFLD.

ABSTRACT

Decoction is the most commonly used dosage form in the clinical treatment of traditional Chinese medicine (TCM). During boiling, the violent movement of various active ingredients in TCM creates molecular forces such as hydrogen bonding, π-π stacking, hydrophobic interactions and electrostatic interactions, which results in the formation of self-assembled aggregates in decoction (SADs), including particles, gels, fibers, etc. It was found that SADs widely existed in decoction with biological activities superior to both effective monomers and their physical mixtures, providing a new idea to reveal the pharmacodynamic material basis of Chinese herbal medicine from the perspective of component interactions-phase structure. Recently, SADs have become a novel focus of research in TCM. This paper reviewed their relevant studies in recent years and found some issues to be concerned in the research, such as the polydispersity of decoction system, instability of active ingredient interactions during boiling, uncertainty of the aggregates self-assembly rules, and stability, purity, yield of the products. In this regard, some solutions and new ideas were presented for the integrated development and clinical application of SADs.

ABSTRACT

On-site supervision is a risk-based regulatory system that requires the scientific development of supervision plans for quality risks and hidden dangers in pharmaceutical enterprises, the rational allocation of supervision resources based on their risk levels, and the implementation of classified supervision measures. In this study, the quality risk monitoring business support system is set up for pharmaceutical enterprises by establishing the quality risk expert database and quality risk monitoring index system for pharmaceutical enterprises based on the difficulty analysis of on-site drug supervision. Based on this support system, the quality risk classification method, the differentiated spot check strategy and business auxiliary visualization system are established. This support system is used to learn the risk level of pharmaceutical enterprises, so as to innovate supervision methods and optimize monitoring strategies. Taking Jiangxi Province as an example, it is verified that the support system can guide the risk assessment of sample enterprises, can improve the targeting of on-site drug supervision in the process of technical review, scheme editing, on-site implementation and comprehensive evaluation, and can effectively improve the quality and efficiency of supervision.

ABSTRACT

The modernization of traditional Chinese medicine (TCM) theories is not only a prerequisite for the modernization of TCM but also a way to deal with the external environment and the difficulties of its development. The modernization of TCM is based on the premise of maintaining its own characteristics and advantages, and along with the progress of modern science and technology, the entire TCM has undergone new changes and improvements from theory to practice, and has become a scientific system with modern scientific level that adapts to the needs of the times. In the context of the unprecedented profound changes in contemporary TCM academics, this paper puts forward the definition of modernization of TCM theory and argues that the modernized theoretical system of TCM should maintain originality to build the foundation of TCM inheritance, clarify the frontier of the discipline and establish the conceptual system, form an open network to be compatible with multi-disciplinary interaction, incorporate the falsification and establish self-renewal system, creatively transform and innovatively develop, and modernize the interpretation and update the discourse system.

ABSTRACT

Alzheimer's disease (AD) is a neurodegenerative disease often characterized by cognitive impairment in clinical practice. The main pathogenesis includes β amyloid protein (Aβ) excessive deposition, neuroinflammatory response, Tau protein hyperphosphorylation, and other factors, and currently only a few chemical drugs have been approved for clinical treatment of AD. The mechanism of action is relatively single, so it is imperative to find new treatment strategies. Traditional Chinese medicine theory believes that the loss of nourishment in the brain and marrow, as well as the loss of vital energy, is the internal mechanisms underlying the occurrence and development of AD, which runs through the entire treatment process. The pathogenesis of AD is closely related to the inflammasome signaling pathway of nucleotide binding oligomerization domain-like receptor protein 3 (NLRP3). Activating the NLRP3 signaling pathway increases neuroinflammatory response, intervenes in microglial polarization, and regulates Aβ sedimentation, cellular autophagy, brain homeostasis, etc. This article takes the NLRP3 signaling pathway as the starting point to sort out and summarize the upstream and downstream targets under the AD mechanism in the past five years, as well as the research on the NLRP3 signal pathway targets with the participation of the relevant traditional Chinese medicine compounds, such as Danggui Shaoyaosan, modified Shuyu Wan, Qingxin Kaiqiao prescription, Kaixin San, Jiedu Yizhi prescription, and modified Buwang San, traditional Chinese medicine monomer extracts, such as silibinin, Lycium barbarum polysaccharides, liquiritigenin, salidroside, baicalin, cinnamaldehyde, betaine, acacetin, and Hericium erinaceus, and acupuncture and moxibustion. It also reviews the latest achievements in the prevention and treatment of AD. This study provides ideas and directions for in-depth research on the prevention and treatment of cognitive dysfunction related diseases with traditional Chinese medicine.

ABSTRACT

OBJECTIVE@#Based on metabonomics technology of high-performance liquid chromatography-mass spectrometry (HPLC-MS/MS) and hydrogen nuclear magnetic resonance spectroscopy (1H NMR), the pharmacokinetic characteristics and therapeutic mechanism of Rhei Radix et Rhizoma (RhRR, Dahuang in Chinese), Eupolyphaga Steleophaga (EuS, Tubiechong in Chinese) combined with RhRR acting on acute liver injury were explored.@*METHODS@#Models of acute liver injury were established, and the pharmacokinetic methods of five components of RhRR-EuS in rats were found by HPLC-MS/MS. The liver tissues of different groups of mice were analyzed by 1H NMR spectroscopy combined with multivariate statistical analysis to investigate the metabolomics of RhRR-EuS and RhRR.@*RESULTS@#Pharmacokinetic results showed there were different levels of bimodal phenomenon in different groups, and the absorption of free anthraquinone in RhRR increased after compatibility with EuS. In addition, the pathological state of acute liver injury in rats can selectively promote the absorption of emodin, chrysophanol, physcion and aloe emodin. Through 15 differential metabolites in the liver tissue of acute liver injury mice, it was revealed that RhRR-EuS and RhRR could protect the liver injury by regulating the metabolism of glutamine and glutamic acid, alanine, aspartic acid and glutamic acid, and phosphoinositide. However, the regulation of RhRR was weaker than that of RhRR-EuS.@*CONCLUSION@#For the first time, we studied the pharmacokinetics and metabolomics differences of RhRR-EuS and RhRR in rats and mice with acute liver injury, in order to provide theoretical reference for clinical treatment of liver disease by DHZCP.

ABSTRACT

PURPOSE@#To identify the potential target genes of blast lung injury (BLI) for the diagnosis and treatment.@*METHODS@#This is an experimental study. The BLI models in rats and goats were established by conducting a fuel-air explosive power test in an unobstructed environment, which was subsequently validated through hematoxylin-eosin staining. Transcriptome sequencing was performed on lung tissues from both goats and rats. Differentially expressed genes were identified using the criteria of q ≤ 0.05 and |log2 fold change| ≥ 1. Following that, enrichment analyses were conducted for gene ontology and the Kyoto Encyclopedia of Genes and Genomes pathways. The potential target genes were further confirmed through quantitative real-time polymerase chain reaction and enzyme linked immunosorbent assay.@*RESULTS@#Observations through microscopy unveiled the presence of reddish edema fluid, erythrocytes, and instances of focal or patchy bleeding within the alveolar cavity. Transcriptome sequencing analysis identified a total of 83 differentially expressed genes in both rats and goats. Notably, 49 genes exhibited a consistent expression pattern, with 38 genes displaying up-regulation and 11 genes demonstrating down-regulation. Enrichment analysis highlighted the potential involvement of the interleukin-17 signaling pathway and vascular smooth muscle contraction pathway in the underlying mechanism of BLI. Furthermore, the experimental findings in both goats and rats demonstrated a strong association between BLI and several key genes, including anterior gradient 2, ankyrin repeat domain 65, bactericidal/permeability-increasing fold containing family A member 1, bactericidal/permeability-increasing fold containing family B member 1, and keratin 4, which exhibited up-regulation.@*CONCLUSIONS@#Anterior gradient 2, ankyrin repeat domain 65, bactericidal/permeability-increasing fold containing family A member 1, bactericidal/permeability-increasing fold containing family B member 1, and keratin 4 hold potential as target genes for the prognosis, diagnosis, and treatment of BLI.

ABSTRACT

Purpose@#To evaluate the incidence and identify the risk factors for radiotherapy-induced oral mucositis among patients with nasopharyngeal carcinoma. @*Methods@#A meta-analysis was conducted. Eight electronic databases (Medline, Embase, Cochrane Library, CINAHL Plus with Full Text, Web of Science, China National Knowledge Infrastructure, Wanfang Database, and Chinese Scientific Journals Database) were systematically searched from inception to 4 March 2023 for relevant studies. Study selection and data extraction were conducted by two independent authors. The Newcastle‒Ottawa scale was used for quality assessment among the included studies. Data synthesis and analyses were performed in R software package version 4.1.3 and Review Manager Software 5.4. The pooled incidence was calculated using proportions with 95% confidence intervals (CIs), and the risk factors were evaluated using the odds ratio (OR) with 95% CIs. Sensitivity analysis and predesigned subgroup analyses were also conducted. @*Results@#A total of 22 studies published from 2005 to 2023 were included. The results of the meta-analysis showed that the incidence of radiotherapy-induced oral mucositis was 99.0% among nasopharyngeal carcinoma patients, and the incidence of severe radiotherapy-induced oral mucositis was 52.0%. Poor oral hygiene, overweight before radiotherapy, oral pH < 7.0, the use of oral mucosal protective agents, smoking, drinking, combined chemotherapy, and the use of antibiotics at early treatment stage are risk factors for severe radiotherapy-induced oral mucositis. Sensitivity analysis and subgroup analyses also revealed that our results are stable and reliable. @*Conclusions@#Almost all patients with nasopharyngeal carcinoma have suffered from radiotherapy-induced oral mucositis, and more than half of patients have experienced severe oral mucositis. Facilitating oral health might be the key focus of reducing the incidence and severity of radiotherapy-induced oral mucositis among nasopharyngeal carcinoma patients.Registration numberCRD42022322035.

ABSTRACT

Chinese patent medicine (CPM) is an important part of traditional and Chinese medicine (TCM). Its quality has direct impact on the safety and effectiveness of clinical use. The quality standard is the pivotal approach to guarantee the quality of CPM. Due to the complex material basis, multitudinous quality influencing factors and unveiled active ingredients, dose-effect relationship and action mechanism, the investigation on quality standard faces many difficulties. This paper surveys the current quality status of CPM and the general situation of CPM standards. At present, the dosing problem has the crucial impact on the quality of CPM. The current quality standard system of CPM is confirmed and the limitations are indicated. Based on the above analysis, the principles and considerations on investigation of quality standard are proposed as follows: ① Adhere to safety as the bottom line, strengthen the risk-control ability of the standard of CPM; ② Adhere to theory of TCM and comprehensive quality, improve the integrative control level of the CPM standard; ③ Emphasize technological development and innovation, promote the quality control competence of CPM standard; ④ Facilitate planning and coordination, optimize the management of the CPM standard system; ⑤ Reinforce investigation on evaluation method, develop grade evaluation standard, accelerate high-quality development of CPM. Finally, the future perspective on investigation of CPM quality standard is prospected.

ABSTRACT

In this study, the mechanism of Xiaoyan Lidan formula (XYLDF) against 3,5-diethoxycarbonyl-1,4-dihydro-2,4,6-collidine (DDC)-induced chronic intrahepatic cholestasis (CIHC) in mice was investigated based on metabolomics, molecular docking and pharmacological methods. In the pharmacodynamics study, a dosage of 5 g·kg-1 (clinical equivalent) XYLDF was administered in DDC-induced mice, then the effect of XYLDF against CIHC was evaluated by measuring the levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (AKP) as well as total bilirubin (TBIL) in serum and observing liver histopathological changes. All experiments were approved by the Ethical Committee Experimental Animal Center of Guangzhou University of Chinese Medicine (ZYD-2021-001). The serum metabolites of mice in each group were detected and identified based on ultra-performance liquid chromatography quadrupole time-of-flight tandem mass spectrometry, and the relevant biological pathways and molecular key targets were further enriched. Molecular docking technology was used to further evaluate the binding activity of the main active ingredients of XYLDF with potential targets. Subsequently, the in vitro experiment was conducted for the validation of the vital target. The results showed that compared with the model group, XYLDF significantly decreased the levels of ALT, AST, AKP and TBIL in the serum of CIHC mice, as well as alleviated inflammatory infiltration and hepatocyte necrosis in liver tissue. According to the metabonomic study, a total of 35 differential metabolites was identified as biomarkers associated with cholestasis, 12 of which were significantly recovered by XYLDF treatment. These biomarkers were involved in the pathways of primary bile acid biosynthesis and linoleic metabolism, which are closely related to the mechanism of XYLDF against CIHC. Protein-protein interaction network indicated that cytochrome P450 3A4 (CYP3A4) and cytochrome P450 1A1 (CYP1A1) are significant potential targets with good binding properties with six major active ingredients of XYLDF. Furthermore, it was found that 4-methoxy-5-hydroxycanthin-6-one, dehydroandrographolide and isodocarpin, three of the main active components in XYLDF, markedly induced the expression of CYP3A4 mRNA in vitro. This study revealed that XYLDF mainly mediates the biosynthesis of bile acids in CIHC mice to improve liver tissue lesions and bile efflux disorders, among which, CYP3A4 is the key target in the protection of XYLDF against CIHC. This research provides a reference for further elucidation of the pharmacological mechanism of XYLDF.

ABSTRACT

OBJECTIVE@#To explore the effect of leucine-rich α-2-glycoprotein (LRG1) derived from hepatocytes on activation of hepatic M1 Kupffer cells.@*METHODS@#A metabolic dysfunction-associated fatty liver disease (MAFLD) model was established in BALB/c mice by high-fat diet (HFD) feeding for 16 weeks. Oleic acid was used to induce steatosis in primary cultures of mouse hepatocytes. The mRNA and protein expressions of LRG1 in mouse liver tissues and hepatocytes were detected by real-time PCR and Western blotting. Primary hepatic macrophages were stimulated with the conditioned medium (CM) from steatotic hepatocyte along with LRG1 or transforming growth factor-β1 (TGF-β1), or both for 24 h, and the expression levels of inducible nitric oxide synthase (iNOS) was detected with Western botting, and the mRNA expressions of iNOS, chemokine ligand 1 (CXCL-1) and interleukin-1β (IL-1β) were measured by RT-PCR. The MAFLD mice were injected with LRG1 (n=6), TGF-β1 (n=6), or both (n=6) through the caudal vein, and the live tissues were collected for HE staining and immumohistochemical detection of F4/80 expression; the mRNA expressions of iNOS, CXCL-1 and IL-1β in liver tissues were detected using RT-PCR.@*RESULTS@#The mRNA and protein expression levels of LRG1 were significantly downregulated in the liver tissues of MAFLD mice and steatotic hepatocytes (P < 0.05). Treatment of the hepatic macrophages with CM from steatosis hepatocytes significantly enhanced the mRNA expression levels of iNOS, CXCL-1 and IL-1β, and these changes were significantly inhibited by the combined treatment with TGF-β1 and LRG1 (P < 0.05). In MAFLD mice, injections with either LRG1 or TGF-β1 alone reduced hepatic lipid deposition and intrahepatic macrophage infiltration, and these effects were significantly enhanced by their combined treatment, which also more strongly inhibited the mRNA expression levels of iNOS, CXCL-1 and IL-1β (P < 0.05).@*CONCLUSION@#LRG1 inhibits hepatic macrophage infiltration by enhancing TGF-β1 signaling to alleviate fatty liver inflammation in MAFLD mice.

ABSTRACT

OBJECTIVE@#To analyze the association between outdoor artificial light-at-night (ALAN) exposure and overweight and obesity among children and adolescents aged 9 to 18 years in China.@*METHODS@#Using follow-up data of 5 540 children and adolescents aged 9 to 18 years conducted from November 2019 to November 2020 in eight provinces of China, latitude and longitude were determined based on school addresses, and the mean monthly average nighttime irradiance at the location of 116 schools was extracted by the nearest neighbor method to obtain the mean outdoor ALAN exposure [unit: nW/(cm2·sr)] for each school. Four indicators of overweight and obesity outcomes were included: Baseline overweight and obesity, persistent overweight and obesity, overweight and obesity progression and overweight and obesity incidence. Mixed effects Logistic regression was used to explore the association between ALAN exposure levels (divided into quintiles Q1-Q5) and baseline overweight and obesity, persistent overweight and obesity, overweight and obesity progression and overweight and obesity incidence. In addition, a natural cubic spline function was used to explore the exposure response association between ALAN exposure (a continuous variable) and the outcomes.@*RESULTS@#The prevalence of baseline overweight and obesity, persistent overweight and obesity, overweight and obesity progression and overweight and obesity incidence among the children and adolescents in this study were 21.6%, 16.3%, 2.9% and 12.8%, respectively. The OR value for the association between ALAN exposure and baseline overweight and obesity was statistically significant when ALAN exposure levels reached Q4 or Q5, 1.90 (95%CI: 1.26-2.86) and 1.77 (95%CI: 1.11-2.83), respectively, compared with the children and adolescents in the Q1 group of ALAN exposure. Similar to the results for baseline overweight and obesity, the OR values for the association with persistent overweight and obesity were 1.89 (95%CI: 1.20-2.99) and 1.82 (95%CI: 1.08-3.06) when ALAN exposure levels reached Q4 or Q5, respectively, but none of the OR values for the association between ALAN and overweight and obesity progression and overweight and obesity incidence were statistically significant. Fitting a natural cubic spline function showed a non-linear trend between ALAN exposure and persistent overweight and obesity.@*CONCLUSION@#There is a positive association between ALAN exposure and overweight and obesity in children and adolescents, and the promotion of overweight obesity in children and adolescents by ALAN tends to have a cumulative effect rather than an immediate effect. In the future, while focusing on the common risk factors for overweight and obesity in children and adolescents, there is a need to improve the overweight and obesity-causing nighttime light exposure environment.

ABSTRACT

OBJECTIVE@#To assess whether the use of Tanreqing (TRQ) Injection could show improvements in time to extubation, intensive care unit (ICU) mortality, ventilator-associated events (VAEs) and infection-related ventilator associated complication (IVAC) among patients receiving mechanical ventilation (MV).@*METHODS@#A time-dependent cox-regression analysis was conducted using data from a well-established registry of healthcare-associated infections at ICUs in China. Patients receiving continuous MV for 3 days or more were included. A time-varying exposure definition was used for TRQ Injection, which were recorded on daily basis. The outcomes included time to extubation, ICU mortality, VAEs and IVAC. Time-dependent Cox models were used to compare the clinical outcomes between TRQ Injection and non-use, after controlling for the influence of comorbidities/conditions and other medications with both fixed and time-varying covariates. For the analyses of time to extubation and ICU mortality, Fine-Gray competing risk models were also used to measure competing risks and outcomes of interest.@*RESULTS@#Overall, 7,685 patients were included for the analyses of MV duration, and 7,273 patients for the analysis of ICU mortality. Compared to non-use, patients with TRQ Injection had a lower risk of ICU mortality (Hazards ratios (HR) 0.761, 95% CI, 0.581-0.997), and was associated with a higher hazard for time to extubation (HR 1.105, 95% CI, 1.005-1.216), suggesting a beneficial effect on shortened time to extubation. No significant differences were observed between TRQ Injection and non-use regarding VAEs (HR 1.057, 95% CI, 0.912-1.225) and IVAC (HR 1.177, 95% CI, 0.929-1.491). The effect estimates were robust when using alternative statistic models, applying alternative inclusion and exclusion criteria, and handling missing data by alternative approaches.@*CONCLUSION@#Our findings suggested that the use of TRQ Injection might lower mortality and improve time to extubation among patients receiving MV, even after controlling for the factor that the use of TRQ changed over time.

ABSTRACT

OBJECTIVE@#To investigate the status quo of recognition and management of renal colic among urological surgeons in China.@*METHODS@#From November 2021 to March 2022, 725 urological surgeons in China were surveyed in the form of a questionnaire, including their province, hospital grade, professional title, the number of patients with renal colic treated per week, the preferred drugs and the cognition of the disease. This study was approved by the Medical Ethics Committee of Peking University People's Hospital, and all respondents completed informed consent online.@*RESULTS@#During November 2021 and March 2022, urological surgeons across China were surveyed in the form of a questionnaire, and the reliability and validity of the questionnaire were verified before the study was carried out. In the study, 720 valid questionnaires were collected (accounting for 99.31% of the total number), in which 42.4% of the doctors' preferred drugs were non-steroidal anti-inflammatory drugs (NSAIDs), and 40.0% of the doctors' preferred antispasmodic drugs. Opioids were the first choice of 11.0% of the physicians and other treatments were preferred by 6.6% of physicians. In addition, 61.1% of the doctors thought that the mechanism of renal colic was elevated prostaglandin, 32.2% thought it was ureteral spasm, 5.0% thought it was calculi irritation, and 1.7% thought the mechanism was unclear. The doctor of the cognition of the generation mechanism of renal colic pain had a significant influence on the preferred treatment option (χ2=54.399, P < 0.001) that the "elevated prostaglandins" doctor more often preferred NSAIDs than the doctor who thought cramps and ureter stones caused renal colic (51.6% vs. 28.0%, χ2=34.356, P < 0.001;51.6% vs. 19.4%, χ2=13.759, P < 0.001). In addition, hospital class, physician title, and the number of weekly consultations by physicians influenced the choice of medications for renal colic (P < 0.05), tertiary hospitals, middle and senior professional titles and weekly patients with renal colic > 8 cases generally preferred NSAIDs.@*CONCLUSION@#There are deficiencies in the cognition and drug treatment of renal colic among urological surgeons in China. The choice of the preferred drug was related to the doctor's cognition of the disease, the grade of the hospital, the doctor's professional title and the weekly treatment volume.

ABSTRACT

OBJECTIVE@#To explore the impacts of delayed ureteral stent removal on the quality of life (QoL) and mental health of urinary calculi postoperative patients due to the corona virus disease 2019(COVID-19) pandemic.@*METHODS@#The demographic and clinical data of patients with ureteral stent placement after urinary endoscopic lithotripsy and returned to Peking University People's Hospital for stent removal from December 2019 to June 2020 were collected. Ureteral stent symptoms questionnaire (USSQ) score and the outcome 20-item self-rating anxiety scale (SAS) and self-rating depression scale (SDS) were collected to estimate the QoL and mental status. The USSQ consisted of 44 questions in 6 domains (including urinary symptom, physical pain, general health, work performance, sexual function, and ureteral stent related infection). For most questions in each domain, its score was a five-point Likert-type scale from 1 to 5, and a small proportion of questions was quantified by 1 to 4 or 1 to 7 scale. SAS and SDS both contained 20 questions used to assess a patient's level of anxiety and depression. Its scoring for each item was on a four-point Likert-type scale from 1 to 4. A total score (ranging from 20 to 80) was the main statistical indicator. The level of clinical anxiety and depression was quantified by using standard scores (total score multiplied by 1.25 to produce integers). And the multi-group structural equation model was constructed by analysis of moment structure (AMOS) analysis.@*RESULTS@#Overall, 71 patients were enrolled for analysis. It was found that the median duration of ureteral stent time differed significantly between the control and delayed groups for 32 (30, 33) d and 94.5 (88, 103) d, respectively. The delayed group resulted in higher scores in the USSQ multidimensional, which included urinary symptoms, general health, work performance and ureteral stent related infections. Anxiety and depression were also significantly serious in the delayed group than in the control group. A longer indwelling time of a ureteral stent could exacerbate the effects of urinary symptoms and physical pain on work performance (P=0.029 < 0.05). Among them, the patients with severe urinary symptoms leading to poor work performance were most significantly affected by prolonged ureteral stent duration time (CR=2.619>1.96).@*CONCLUSION@#Patients with delayed ureteral stent removal due to the COVID-19 had resulted in worse QoL and mental status. Stents related symptoms are more severe in patients with higher anxiety and depression degree during COVID-19. To improve the QoL and mental health of patients after urinary calculi surgery during COVID-19, it is still not recommended to prolong the stent duration time or corresponding intervention measures should be taken.

ABSTRACT

OBJECTIVE@#This study aimed to estimate spatiotemporal variations of global heat-related cardiovascular disease (CVD) burden from 1990 to 2019.@*METHODS@#Data on the burden of heat-related CVD were derived from the Global Burden of Disease Study 2019. Deaths and disability-adjusted life years (DALYs) were used to quantify heat-induced CVD burden. We calculated the age-standardized mortality rate (ASMR) and DALY rate (ASDR) per 100,000 population to compare this burden across regions. Generalized linear models were applied to evaluate estimated annual percentage changes (EAPC) for temporal trends from 1990 to 2019. The correlation between the socio-demographic index (SDI) and age-standardized rate was measured using the Spearman rank test.@*RESULTS@#Heat-induced CVD caused approximately 90 thousand deaths worldwide in 2019. Global ASMR and ASDR of heat-related CVD in 2019 were 1.17 [95% confidence interval ( CI): 0.13-1.98] and 25.59 (95% CI: 2.07-44.17) per 100,000 population, respectively. The burden was significantly increased in middle and low-SDI regions and slightly decreased in high-SDI regions from 1990 to 2019. ASMR showed an upward trend, with the most considerable increase in low-latitude countries. We observed a negative correlation between SDI and EAPC in ASMR ( r s = -0.57, P < 0.01) and ASDR ( r s = -0.59, P < 0.01) among 204 countries.@*CONCLUSION@#Heat-attributable CVD burden substantially increased in most developing countries and tropical regions.

ABSTRACT

OBJECTIVE@#To evaluate the trend of notified incidence of pulmonary tuberculosis (PTB) in China at different periods by population and region and to explore the effect of TB prevention and control in recent years.@*METHODS@#Using pooled data on TB cases reported by the TB Information Management Reporting System (TBIMS) from 2005 to 2020, we calculated the annual percentage change (APC) using the Joinpoint regression model.@*RESULTS@#From 2005 to 2020, a total of 16.2 million cases of PTB were reported in China, with an average notified incidence of 75.5 per 100,000 population. The age standardization rate (ASR) continued to decline from 116.9 (/100,000) in 2005 to 47.6 (/100,000) in 2020, with an average annual decrease of 5.6% [APC = -5.6, 95% confidence interval ( CI): -7.0 to -4.2]. The smallest decline occurred in 2011-2018 (APC = -3.4, 95% CI: -4.6 to -2.3) and the largest decrease in 2018-2020 (APC = -9.2, 95% CI: -16.4 to -1.3). From 2005 to 2020, the ASR in males (159.8 per 100,000 in 2005, 72.0 per 100,000 in 2020) was higher than that in females (62.2 per 100,000 in 2005, 32.3 per 100,000 in 2020), with an average annual decline of 6.0% for male and 4.9% for female. The average notified incidence was the highest among older adults (65 years and over) (182.3/100,000), with an average annual decline of 6.4%; children (0-14 years) were the lowest (4.8/100,000), with an average annual decline of 7.3%, but a significant increase of 3.3% between 2014 and 2020 (APC = 3.3, 95% CI: 1.4 to 5.2); middle-aged (35-64 years) decreased by 5.8%; and youth (15-34 years) decreased by an average annual rate of 4.2%. The average ASR in rural areas (81.3/100,000) is higher than that in urban areas (76.1/100,000). The average annual decline in rural areas was 4.5% and 6.3% in urban areas. South China had the highest average ASR (103.2/100,000), with an average annual decline of 5.9%, while North China had the lowest (56.5/100,000), with an average annual decline of 5.9%. The average ASR in the southwest was 95.3 (/100,000), with the smallest annual decline (APC = -4.5, 95% CI: -5.5 to -3.5); the average ASR in the Northwest China was 100.1 (/100,000), with the largest annual decline (APC = -6.4, 95% CI: -10.0 to -2.7); Central, Northeastern, and Eastern China declined by an average of 5.2%, 6.2%, and 6.1% per year, respectively.@*CONCLUSIONS@#From 2005 to 2020, the notified incidence of PTB in China continued to decline, falling by 55%. For high-risk groups such as males, older adults, high-burden areas in South, Southwest, and Northwest China, and rural regions, proactive screening should be strengthened to provide timely and effective anti-TB treatment and patient management services for confirmed cases. There is also a necessity to be vigilant about the upward trend of children in recent years, the specific reasons for which need to be further studied.

ABSTRACT

Objective: To describe fertility and explore factors associated with it among pre-conception couples of childbearing age. Methods: Based on the pre-conceptional offspring trajectory study of the School of Public Health of Fudan University, couples of childbearing age who participated in the pre-conception physical examination in Shanghai Jiading District from 2016 to 2021 were recruited and followed up. Couples' time to pregnancy (TTP) was analyzed and Cox proportional hazards regression model was used to explore the factors associated with TTP. Kaplan-Meier was used to calculate each menstrual cycle's cumulative pregnancy rate. Results: A total of 1 095 preconception couples were included in the analysis, the M(Q1,Q3)of TTP was 4.33 (2.41, 9.78) menstrual cycles. Age of women (FR=0.90, 95%CI: 0.85-0.95, P<0.001), women who were overweight or obese before pregnancy (FR=0.36, 95%CI: 0.24-0.55, P<0.001), women who were exposed to second-hand smoking (FR=0.63, 95%CI: 0.44-0.92, P=0.016), women whose home or office had been renovated in the past 2 years and had a particular smell (FR=0.46, 95%CI: 0.26-0.81, P=0.008) were risk factors for impaired fertility. Regular menstrual cycles (FR=1.64, 95%CI: 1.16-2.31, P=0.005), females who often drank tea/coffee (FR=1.55, 95%CI: 1.11-2.17, P=0.011) and males who took folic acid before conception (FR=2.35, 95%CI: 1.38-4.23, P=0.002) were associated with better fertility. The cumulative pregnancy rate of 3, 6, and 12 menstrual cycles was 37.6%, 64.4%, and 78.4%, respectively. Conclusion: Older couples, overweight or obesity before pregnancy, irregular menstruation, exposure to secondhand smoke and decoration pollutants in females are associated with impaired fertility. Frequent tea/coffee drinking before pregnancy in females and taking folic acid before pregnancy in males are associated with shortened conception time.

ABSTRACT

Based on qi-depression constitution, we systematically sorted out and summarized the manifestations of specific symptoms and prescriptions of qi-depression constitution. It is believed that a series of syndromes can be developed due to the imbalance in patients with qi-depression constitution. The four most common syndromes inclinic were summarized as liver depression, deficient depression, phlegm-heat depression, and stagnation. “Liver depression” resulted from liver failing to free flow of qi, then qi stagnated, so Xiaoyao Powder (逍遥散) was recommended as treatment for liver qi depression, spleen deficiency and blood insufficiency; Danzhi Xiaoyao Powder (丹栀逍遥散) for liver depression and spleen deficiency, depression transforming into fire; Bentun Decoction (奔豚汤) for liver depression transforming into fire, upward rushing of qi counterflow. “Deficient depression” resulted from long-term mental disorder and will consume qi and blood potentially to qi and blood deficiency, so Ganmai Dazao Decoction (甘麦大枣汤) was recommended as treatment for deficiency of both heart and spleen, and heart and spleen failing to tonify; Baihe Dihuang Decocotion (百合地黄汤) for heart and lung with yin deficiency, spirit and soul failing to guard. “Phlegm-heat depression” resulted from disturbance of qi movement, affecting the transportation of essence, blood and body fluids, gathering dampness and forming phlegm into heat. Banxia Houpo Decoction (半夏厚朴汤) was recommended as treatment for liver depression and failing to transportation, phlegm coagulation and qi stagnation; Chaihu (or Chaiqin) Wendan Decoction (柴胡(芩)温胆汤) for liver depression and phlegm-heat harassing internally, and disharmony of gallbladder and stomach; self-made Shugan Jieyu Decoction (舒肝解郁汤) for liver-qi stagnation and phlegm-fire harassing internally. “Stagnation” resulted from stagnation of Qi and blood, accumulation of turbid phlegm, and forming stasis over time, so Yueju Pill (越鞠丸) was recommended as treatment for liver depression and failing to transportation, phlegm-fire with damp diet and blood depression; self-made Rupi Sanjie Decoction (乳癖散结汤) for liver depression, stagnation of Qi and blood.

ABSTRACT

ObjectiveTo characterize a cluster epidemic of coronavirus disease 2019 (COVID-19)on campus in Baotou city and provide evidence for the prevention and control of COVID-19 in universities. MethodsField epidemiological investigation was conducted to determine the confirmed cases and close contacts in the cluster epidemic of COVID-19 in a university of western China in 2022. Descriptive analysis was utilized to illustrate the epidemic timeline and schematic diagram. Real-time quantitative fluorescent PCR(RT-PCR) was used to detect the nucleic acid of SARS-CoV-2 in the collected samples. ResultsA total of eight students were infected in the cluster epidemic on campus, including 2 confirmed cases and 6 asymptomatic cases. Case A1 infected other 7 students in the same dormitory or on the same floor by close contact. After a 10-day quarantine and medical observation, no further case was reported. The overall incidence rate was 1.22% and the incidence rate among close contacts was 2.24%. ConclusionThis cluster epidemic of COVID-19 is characterized by strong and fast transmission. Repeated contact with no personal protection in confined space is highly vulnerable to cluster epidemic. Prevention of cluster epidemics on campus remains crucial to contain the epidemic. Therefore, it is necessary to strengthen the management of campus containment, interrupt the transmission route, identify close contacts and implement quarantine management as early as possible to avoid the cluster epidemics on campus.
