ObjectiveThis study employed the scoping review method to systematically retrieve and analyze the basic information and clinical research evidence of expensive Chinese patent medicines （CPMs）， aiming to provide a basis for future related research and clinical applications. MethodsEight Chinese and English databases were systematically searched for the clinical research evidence on expensive CPMs. ResultsEleven expensive CPMs （Angong Niuhuang Wan， Jufang Zhibao Wan， Suhexiang Wan， Pien Tze Huang， Niuhuang Qingxin Wan， Qinggong Shoutao Wan， Compound Realgar Natural Indigo Tablets， Xihuang Wan， Dingkun Wan， Babao Wan， and Guilingji Capsules） were selected. A total of 365 related studies were included in this review， comprising 331 clinical studies （of which 291 were randomized controlled trials）， 30 systematic reviews and Meta-analyses， 3 expert consensus， and 1 rapid health technology assessment. Among the 11 CPMs， 2（Angong Niuhuang Wan and Jufang Zhibao Wan） had a daily price over 500 yuan. The famous and precious Chinese medicinal materials involved included Moschus （frequency of 7）， Bovisc Alculus （7）， and Borneol （5）. The dosage forms included pills， capsules， oral liquid， tablets， and lozenges. The diseases treated by these CPMs mainly included malignant tumors， cerebrovascular diseases， gynecological diseases， and hepatobiliary system diseases. The sample sizes of the clinical studies were mainly concentrated within the range of 51-100 cases， and the main control form was CPM + basic Western medicine treatment vs. basic Western medicine treatment. The 331 clinical studies reported a total of 44 adverse events occurred， of which 36 were determined to be adverse reactions. ConclusionThe scarcity of raw materials leads to the high prices of expensive CPMs. The difficulty of conducting clinical research and the critical and severe cases treated lead to a lack of clinical research evidence with large sample sizes. The uneven distribution of existing studies， incomplete information on medicine package， and non-standard clinical research designs remain to be addressed in the future.

Kounis syndrome is an acute coronary syndrome triggered by an allergic reaction, which is clinically rare and frequently subject to misdiagnosis or missed diagnosis. This article presents a case report of a 70-year-old male patient who developed a rash, pruritus, and chest pain following colon polyp resection. Coronary angiography revealed occlusion of the left anterior descending artery, and blood flow was restored after stent implantation. However, the patient experienced recurrent symptoms accompanied by loss of consciousness. Drug skin tests confirmed positive reactions to chlorhexidine and fondaparinux sodium, leading to a diagnosis of type Ⅱ Kounis syndrome. By avoiding allergenic drugs and combining antihistamines with symptomatic treatment to correct myocardial ischemia, the patient′s clinical symptoms significantly improved, and he eventually recovered and was discharged from the hospital. This case underscores the importance of maintaining vigilance for this syndrome in patients with allergies accompanied by chest pain and promptly identifying and avoiding allergens.

Objective:To explore the factors influencing adherence to voice therapy among patients with voice disorders in China. Methods:Patients with voice disorders who visited the Voice Therapy Center at Sun Yat-sen Memorial Hospital, Sun Yat-sen University, from February to May 2022 were enrolled in the study. Adherence was assessed using the URICA-Voice scale, while influencing factors were assessed through the Voice Handicap Index（VHI） scale and a general information questionnaire. Correlation analysis was conducted using univariate and multivariate logistic regression analysis. Results:A total of 247 patients were included in the study, comprising 57 males（23.08%） and 190 females（76.92%）. The results revealed that: ①Female patients demonstrated higher likelihood of being in the contemplation stage（OR=0.22） compared to males. ②Patients with a monthly family income per capita>6 000 yuan were more likely to be in the contemplation stage than those with<3 000 yuan with an OR = 13.94. ③High vocal-demand occupations increased contemplation stage probability（OR=7.70） compared to moderate-demand occupations. ④Residence within 30-minute commute predicted action/maintenance stages（OR=7.14） versus≥60-minute commute. ⑤Patients whose occupations had high voice demands were more likely to be in the action and maintenance stages than those with average voice demands, with an OR of 16.20. Conclusion:Gender, monthly family income per capita, occupational voice demands, and distance to the hospital significantly impact the URICA-Voice compliance stages of patients. Patients who are female, have higher family income, have occupations with high voice demands, and live closer to the hospital exhibit higher compliance with voice training.

In the century-long evolution of insulin pharmaceuticals, each transformative advancement in this drug class has been closely tied to the ability to obtain new insulin isoforms for research. Despite this, the recently discovered naturally occurring isoforms of glycosylated human insulin have remained largely unattainable for proper characterization. Herein, we demonstrate for the first time that total chemical synthesis can be used to generate all isoforms. This achievement required maintaining the correct positions of the interchain disulfide bonds while effectively removing protecting groups on complex glycans. Notably, the availability of seven glycoforms reveals the important effects of natural sialylated glycans in suppressing insulin self-association and enhancing its solubility, surpassing the performance of currently employed rapid-acting insulin drugs. This work not only offers a readily adaptable platform for exploring natural O-glycosylation in other therapeutic proteins and peptides but also lays the groundwork for further research into harnessing natural glycosylation for therapeutic applications.

In this study, we employed a combination of genome mining and heteronuclear single quantum coherence (HSQC)-based small molecule accurate recognition technology (SMART) technology to search for fernane-type triterpenoids. Initially, potential endophytic fungi were identified through genome mining. Subsequently, fine fractions containing various fernane-type triterpenoids were selected using HSQC data collection and SMART prediction. These triterpenoids were then obtained through targeted isolation and identification. Finally, their antifungal activity was evaluated. As a result, three fernane-type triterpenoids, including two novel compounds, along with two new sesquiterpenes and four known compounds were isolated from one potential strain, Diaporthe discoidispora. Their structures were elucidated through analysis of high-resolution electrospray ionization mass spectrometry (HR-ESI-MS) and nuclear magnetic resonance (NMR) spectroscopic data. The absolute configurations were determined using single-crystal X-ray diffraction analysis and electron capture detector (ECD) analysis. Compound 3 exhibited moderate antifungal activity against Candida albicans CMCC 98001 and Aspergillus niger.

Nonalcoholic steatohepatitis （NASH） is a chronic liver disease with the main pathological features of hepatic steatosis， inflammatory cell infiltration， and interstitial fibroplasia， and it is an important risk factor for liver fibrosis， liver cirrhosis， and hepatocellular carcinoma. NOD-like receptor protein 3 （NLRP3） inflammasome is the core of innate immunity， and the abnormal activation of NLRP3 inflammasome is closely associated with the development and progression of NASH， which involves multiple links such as inflammatory response and oxidative stress. A large number of studies have shown that the active ingredients of traditional Chinese medicine （TCM） and TCM compound prescriptions can improve oxidative stress， regulate lipid metabolism， and alleviate liver inflammation by regulating NLRP3 inflammasome. TCM treatment applied in clinical practice has achieved a good therapeutic effect， while inflammasome is one of the key pathways or targets for TCM in improving NASH. This article reviews the mechanism of action of NLRP3 inflammasome in NASH and the research advances in TCM intervention of NLRP3 inflammasome， in order to provide ideas for the clinical TCM treatment of NASH， as well as reference targets and research directions for the research and development of new TCM drugs.

Objective To investigate the factors influencing mood and sleep among special operation personnel,so as to provide evidence for the prevention and intervention of related issues.Methods A total of 600 special operation personnel during their special duty were enrolled by random sampling method.Basic information was collected by a general information questionnaire.Mood and sleep status were evaluated by self-rating anxiety scale(SAS),self-rating depression scale(SDS),and Pittsburgh sleep quality index scale(PSQI).Results Spearman correlation analysis showed that factors associated with anxiety were years of work experience(r=0.099,P=0.016),family residence(r=-0.153,P＜0.001),and sleep status(r=0.199,P＜0.001);the factors associated with depression were relationship with parents(r=-0.134,P=0.001),family residence(r=-0.144,P＜0.001),and sleep status(r=0.122,P=0.003);and the factors associated with sleep were age(r=0.088,P=0.031),years of work experience(r=0.079,P=0.049),and number of children(r=0.083,P=0.043).Binary logistic regression analysis showed that depression was not an influencing factor of sleep(odds ratio[OR]=1.302,95%confidence interval[95%CI]0.759-1.758,P=0.086),while anxiety was an influencing factor of sleep(OR=2.187,95%CI 1.608-4.695,P=0.001).Conclusion The sleep status of special operation personnel investigated in this survey is related to age and years of work experience,and is influenced by anxiety.Therefore,greater attention should be given to sleep issues in the occupational health support of special operations.Additionally,years of work experience,family residence,relationship with parents,and sleep status are related to anxiety and depression among special operation personnel.It is necessary to focus on the mental health of older workers and those with longer tenure.

Objective To investigate the correlation between physical activity duration,sleep quality,weight control,and PRO(patient-reported outcomes)in individuals with hypertension,providing effective information for enhancing patient-reported outcomes in this population.Methods A total of 625 hypertensive patients were randomly selected from four counties in Yunnan Province from April to June 2020 to participate in a field survey.The questionnaire included patients'basic information,lifestyle,health status and the PRO Scale for Hypertension-PROISCD-HY(V1.0).Statistical analyses including t-tests,one-way ANOVA,and multivariate linear regression were conducted to investigate the relationships between physical activity duration,sleep quality,weight control,and PRO,with the Bootstrap method used to examine potential mediating effects.Results After adjusting for potential covariates,the multiple linear regression model indicated a significant association between a physical activity duration of≥2 hours with PRO[B=6.551,95%CI(2.611,10.491)].Stratified analysis showed that this association was only present among males,females,and younger adults,but not in older adults.Additionally,a positive correlation was found between good sleep quality and PRO[B=1.870,95%CI(0.449,3.291)],with this association being consistent across all populations after stratification.Patients who managed their condition through exercise and diet had higher PRO scores[B=1.904,95%CI(0.383,3.424)],while those controlling weight through diet and other methods exhibited a decrease in PRO scores[B=-4.873,95%CI(-7.860,-1.887);B=-7.105,95%CI(-12.211,-1.999)],with variations among different groups.The bootstrap method revealed that physical activity duration had both direct and indirect effects on PRO,with sleep quality acting as a partial mediator between physical activity duration and PRO.Conclusion A Physical activity duration of at least 2 hours,good sleep quality,and weight control have been shown to improve PRO in individuals with hypertension.

[Objective] To establish a real-time fluorescence quantitative PCR nucleic acid detection method of human parvovirus B19 and validate the method systematically. [Methods] Specific primers and probes for the highly conserved regions of the three genotypes of B19 virus were designed, and B19 quantitative amplification standard curves were established. The accuracy, precision (repeatability and intermediate precision), linear range, quantification limit, detection limit, specificity, anti cross contamination, genotyping and anti-interference ability of this method were verified. [Results] When the quantitative reference range for B19 virus was 2.0×10¹ to 1.0×10⁸ IU/mL, a double logarithmic regression analysis was performed between the measured values and the theoretical values, and the regression equation R²≥0.98 showed good linear correlation. The quantification limit was 20 IU/mL, with a detection rate of 100%. The detection limit was 10 IU/mL, and the detection rate is 95.23%. Three genotypes of B19 virus samples can be effectively detected. The plasma of seven non B19 pathogens, including hepatitis A virus, hepatitis B virus, hepatitis C virus, human immuno-deficiency virus, human cytomegalovirus, hepatitis E virus and Treponema pallidum, was non reactive and has good species specificity. Simultaneously, in the presence of seven other concurrent pathogens, positive samples with a weak positive concentration of E3 IU/mL could be stably detected, and the B19 nucleic acid testing method was not interfered with. When the hemoglobin concentration was 431 mg/dL, triglycerides (1 269 turbidity) and unconjugated bilirubin concentration was 20 mg/dL, this method was non reactive for all three common plasma interfering substances. In the presence of three common plasma interfering substances, positive samples with a weak positive concentration of E3 IU/mL could be stably detected, and the B19 nucleic acid testing method was not interfered with. The deviation between the detection values of standard substances at two concentration levels of S1 (E5 IU/mL) and S2 (E4 IU/mL) and the target values were≤±0.5 log value. The CV values of positive sample 1 (concentration level E5 IU/mL) and positive sample 2 (concentration level E4 IU/mL) for daily precision confirmation and continuous 5-day intra-day precision confirmation were both≤5%. [Conclusion] This method has strong specificity, high sensitivity, wide linear range, stability, reliability and high accuracy, and can be used for the detection of human parvovirus B19 nucleic acid in plasma.
