The theory of constitution in traditional Chinese medicine （TCM） has emerged as a new discipline in recent years. Constitution plays a vital role in the onset，progression，transformation，and prognosis of diseases. At present，some clinical scholars have adopted a novel diagnostic and treatment model of "constitution differentiation-disease identification-syndrome differentiation"，in which constitution is regarded as a core element throughout the diagnostic and therapeutic process. Constitution is closely associated with etiology，onset，pathogenesis，syndrome differentiation，and treatment. Against this background，the construction of animal models based on constitution holds far-reaching significance for advancing clinical research. This paper focuses on the construction and evaluation of rodent models with Qi-deficiency constitution，aiming to explore how to further induce Qi-deficiency syndromes and related disease states on the basis of Qi-deficiency constitution models，thereby developing an integrated animal model that embodies the trinity of "constitution-disease-syndrome". The establishment of this model not only provides a solid experimental foundation for the development of new therapies and drugs in TCM targeting specific constitutions，diseases，and syndromes，but also greatly promotes the modernization and scientific advancement of TCM theory. By comprehensively applying multidisciplinary technologies and methods，the study evaluates the model's validity，reliability，and practicality，with the aim of opening new avenues for future research in TCM and promoting the development of the field.

OBJECTIVE To offer a reference for the treatment of Mycobacterium iranicum infection by analyzing the diagnosis and management of a single case alongside literature-reported cases.METHODS Through case report and literature reviews,this study synthesized the clinical features,therapeutic regimens,and patient outcomes of those infected with M.iranicum.RESULTS In the single case documented in this report,subsequent to clinical pharmacists'involvement in the consultation,the patient was prescribed a therapeutic regimen comprising levofloxacin(0.5 g,qd,ivgtt)+Clarithromycin sustained-release tablets(1 000 mg,qd,po)+Ethambutol tablets(0.75 g,qd,po).The patient exhibited clinical improvement and was discharged after treatment.This article integrated 12 published studies,encompassing 13 patients(7 male and 6 female),of whom 69.23%were aged≥50 years.Patients infected with M.iranicum exhibited non-specific clinical manifestations and imaging features,with pulmonary infection as the primary presentation.Antimicrobial susceptibility test revealed that M.iranicum was susceptible to multiple agents,including amikacin,clarithromycin,linezolid,and ethambutol.The three-drug combination therapy was the most frequently employed regimen.In terms of clinical outcomes,there were 9 cases(69.23%)of clinical cure,3 cases(23.08%)of bacteriological negativity conversion,and 1 case(7.69%)of treatment failure.CONCLUSIONS For M.iranicum infection,a triple-drug therapeutic regimen consisting of three agents with distinct mechanisms of action selected from amikacin,clarithromycin,moxifloxacin,levofloxacin,minocycline,ethambutol,and other relevant drugs may represent a relatively optimal strategy.

Objective To retrospectively study the characteristics and short-term outcomes of patients with decompensated liver cirrhosis accompanied by diastolic cardiac dysfunction,and to inform the clinical diagnosis and treatment of decompensated liver cirrhosis.Methods We retrospectively analyzed the clinical data of patients with liver cirrhosis and diastolic heart dysfunction admitted to Nanfang Hospital of Southern Medical University from April 1,2019 to July 31,2023.The patients were divided into compensated cirrhosis group(n=37)and decompensated cirrhosis group(n=226),and those with decompensated cirrhosis were further divided into subgroups of patients with heart dysfunction(n=84)and patients without heart dysfunction(n=142).We compared two groups using the independent samples t-test and Mann-Whitney U test for continuous data in normal distribution and data in skewed distribution,respectively;compared multiple groups using the Kruskal-Wallis H test,with subsequent paired comparisons using the Wilcoxon test;compared categorical data between two groups using the chi-square test or corrected chi-square test;identified the factors affecting patient survival using a Logistic regression model;and plotted Kaplan-Meier survival curves,with inter-group comparisons using the log-rank test.Results A total of 263 eligible patients were ultimately included,among whom 226 patients were diagnosed with decompensated liver cirrhosis(84 patients with diastolic dysfunction).Between the diastolic dysfunction group and non-diastolic dysfunction group,significant differences were detected in age(t=-4.566,P<0.05),activated partial thromboplastin time(Z=-3.026,P<0.05),prothrombin time(Z=-2.450,P<0.05),international normalized ratio(Z=2.779,P<0.05),and the proportion of moderate esophageal varices(χ2=4.273,P<0.05).During hospitalization,35 patients experienced new or aggravated ascites(18 with cardiac dysfunction and 17 without cardiac dysfunction),6 patients experienced new gastroesophageal variceal bleeding,and 9 patients experienced new or aggravated hepatic encephalopathy(3 with cardiac dysfunction and 6 without cardiac dysfunction).Jaundice was the most common decompensation event upon admission,and electrophysiological abnormalities were the most common electrocardiogram findings upon admission.During the 90-day follow-up period,30 individuals(12 with cardiac dysfunction and 18 without cardia dysfunction)died.The logistic regression analysis showed that age(odds ratio[OR]=1.075,95%confidence interval[CI]:1.033-1.119,P<0.001),N-terminal pro-B-type natriuretic peptide(NT-proBNP,OR=0.996,95%CI:0.992-0.999,P=0.016),and mild/moderate ascites(OR=0.270,95%CI:0.092-0.789,P=0.017)were independent predictive factors for cirrhotic cardiomyopathy.Conclusion Timely attention should be paid to elderly patients with decompensated liver cirrhosis and diastolic heart dysfunction who have a decline in NT-proBNP and mild to moderate ascites.Symptomatic treatment such as diuretics may improve diastolic heart dysfunction.

Objective:To describe the body mass index (BMI) level and long-term trends of Chinese older adults aged 65 and above.Methods:Older adults aged 65 and above from six waves (2002-2018) of the China Longitudinal Healthy Longevity Survey were selected as the study population. Multiple cross-sectional design with six survey waves conducted in 2002, 2005, 2008, 2011, 2014, and 2018 was adopted, enrolling 15 647, 15 358, 15 622, 9 166, 6 302, and 12 417 participants, respectively. Additionally, a total of 13, 755 participants were included in the cohort study design. Relevant information was collected through questionnaires and physical examinations. The χ2 trend test was used to compare the changes in the rates of underweight and overweight/obesity over the years, and the linear mixed-e?ects model (LMM) was used to fit trajectory curves of BMI changes with advancing age in older adults. Results:The baseline ages of the participants included in 2002, 2005, 2008, 2011, 2014, and 2018 were (85.16±11.26), (84.23±11.83), (84.99±12.16), (81.10±11.86), (78.89±11.30), and (83.08±12.42) years, respectively, with a relatively high proportion of females and rural residents. In the cohort study, the 13 755 participants had a median ( Q1, Q3) follow-up time of 6.5 (5.2, 10.0) years, with a cumulative follow-up duration of 109 041 person-years. In each wave, males had higher BMI than females, urban residents had higher BMI than rural residents, and BMI gradually decreased with increasing age (all P<0.001). The mean BMI of older adults in China increased from (19.37±3.80) kg/m2 in 2002 to (22.04±4.01) kg/m2 in 2018 ( P<0.001). Across all survey years, the prevalence of underweight was consistently higher in women than in men and in rural areas than in urban areas, with an upward trend as age increased (all P<0.001). In 2018, the underweight rates in the 65-79, 80-89, 90-99, and ≥100-year-old age groups were 8.0%, 16.7%, 26.2%, and 35.5%, respectively. Meanwhile, the prevalence of overweight/obesity was higher in men than in women and in urban areas than in rural areas, showing a declining trend with advancing age (all P<0.001). The prevalence of underweight among the older adults decreased significantly from 45.2% in 2002 to 18.9% in 2018 ( P<0.001), while the prevalence of overweight/obesity increased from 11.0% in 1998 to 29.6% in 2018 ( P<0.001). The trajectory curves fitted by the LMM model showed that individuals born in later decades had higher BMI levels at the same age compared to earlier cohorts. Conclusion:From 2002 to 2018, the BMI level among Chinese older adults showed an increasing trend. The prevalence of underweight showed a declining trend, while the rates of obesity and overweight increased. However, the underweight rate remained notably high among the oldest old.

Objective:To observe the clinical effect of Cangfu Daotan Decoction combined with ethinylestradiol and cyproterone acetate,metformin in patients with spleen deficiency phlegm-dampness type polycystic ovary syndrome(PCOS)accompanied by insulin resistance.Methods:80 patients with PCOS accompanied by insulin resistance who were admitted to our hospital from June 2023 to June 2024 were included.The patients were divided into control group(treated with ethinylestradiol and cyproterone acetate,metformin)and study group(treated with modified Cangfu Daotan Decoction combine with ethinylestradiol and cyproterone acetate,metformin)by the random number table method,with 40 cases in each group.The total clinical effective rate,TCM syndrome score,sex hormone levels[prolactin(PRL),estradiol(E2),follicle-stimulating hormone(FSH),testosterone(T),and luteinizing hormone(LH)],insulin resistance indicators[fasting insulin(FINS),fasting blood glucose(FBG),homeostatic model assessment of insulin resistance(HOMA-IR)],and endometrial receptivity[pulsatile index(PI),resistance index(RI),endometrial thickness(ET),ovulation rate]and the occurrence of adverse reactions were compared between the two groups.Results:Compared with the control group after treatment,the total clinical effective rate,PRL,E2,FSH level,ET and the ovulation ratein the study group were higher,while the main symptoms,secondary symptoms,total score,T,LH levels,FBG,FINS levels,HOMA-IR,PI and RI were lower(P＜0.05).There was no difference in the incidence of adverse reactions between the two groups(P＞0.05).Conclusion:Cangfu Daotan Decoction combined with ethinylestradiol and cyproterone acetate,metformin in patients with spleen deficiency phlegm-dampness type PCOS accompanied by insulin resistance,can improve the clinical symptoms,increase the total clinical effective rate,it may be related to the regulation of insulin resistance,sex hormone levels,and endometrial receptivity,it is safe and reliable.
