The disease-syndrome combination animal model in traditional Chinese medicine （TCM） andrology serves as an important bridge linking TCM theory with modern medical research， providing a key experimental platform for elucidating the 'syndrome-disease' correlation mechanism in male-specific diseases and for screening effective prescriptions. This article reviews recent progress in animal model research on common TCM andrological diseases， including prostatic diseases， sexual dysfunction， and male infertility， with a focus on analyzing the application， advantages， and disadvantages of various modeling strategies， such as immune induction， hormonal intervention， and multi-factor combination across different syndrome types. However， despite breakthroughs in model construction techniques， current research still faces several challenges， including insufficient standardization of syndrome differentiation and difficulties in quantifying TCM-specific indicators. Future studies need to optimize model evaluation systems by integrating modern technologies， in order to promote the standardization and internationalization of TCM andrology research.

Objective To explore the clinical characteristics of patients with heat illness and the related factors for progression to heatstroke so as to provide a basis for early clinical intervention.Methods A case-control study design was adopted.A total of 164 patients with heat illness admitted to a hospital in Hainan Province from January 2018 to December 2023 were included,and divided into a heatstroke group(21 cases)and a non-heatstroke group(143 cases).Univariate and multivariate logistic regression analyses were used to evaluate the associations of body temperature,heart rate and mean arterial pressure at admission with the progression to heatstroke.Results The incidence of organ dysfunction in the patients with heat illness was 45.12％(74/164),and 12.80％(21/164)progressed to heatstroke.Multivariate logistic regression analysis showed that at admission,body temperature＞40 ℃(OR=10.11,95％CI:2.86～35.78),heart rate＞100 beats/min(OR=9.07,95％CI:2.75～29.94),and mean arterial pressure＜70 mmHg(OR=9.05,95％CI:2.75～29.75)were the related factors affecting the progression of heat illness patients to heatstroke.Conclusion The incidence of organ dysfunction in heat illness patients is relatively high.Body temperature,heart rate and mean arterial pressure at admission may be the related factors for predicting the progression of heat illness to heatstroke.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

OBJECTIVE To analyze the clinical characteristics and the correlation between laboratory indicators and prognosis of severe Mycoplasma pneumoniae pneumonia(SMPP)in children.METHODS A total of 85 children with SMPP admitted to Anhui Provincial Children's Hospital from Nov.2021 to May 2024 were selected as the study subjects.Based on clinical typing at admission,they were divided into a high-risk group(n=59)and a low-risk group(n=26).The clinical manifestations,laboratory indicators and outcomes at 28 days of treatment were compared between the two groups.RESULTS The duration of fever and cough before admission in the high-risk group was(7.17±1.09)days and(6.79±1.25)days,respectively,which was longer than that in the low-risk group(P＜0.05).There were no statistically significant differences in pulmonary auscultation(wheezing rales,moist rales)and extrapulmonary complications between the two groups.The levels of C-reactive protein(CRP),serum amyloid A(SAA),platelets(PLT),fibrinogen(FIB),D-dimer(DD)and N-terminal pro-brain natriuretic peptide(NT-proBNP)in the high-risk group were(11.62±1.45)mg/L,(226.88±36.83)mg/L,(3 18.57±39.82)×109/L,(4.28±0.74)g/L,(0.81±0.12)μg/ml and(2 295.48±413.75)pg/ml,respectively,all of which were higher than those in the low-risk group(P＜0.05).Within 28 days after treatment of children in both groups,one patient in the high-risk group died.CONCLUSIONS Compared with children with SMPP in the low-risk group,those in the high-risk group have a higher risk of prognostic mor-tality,suggesting a correlation between the children's blood CRP,SAA,PLT,FIB,DD and NT-proBNP levels and the prognosis of children with SMPP.

Objective:To investigate the anemia conditions and characteristics of iron metabolism during different stages of pregnancy in women with different genotypes of thalassemia.Methods:This cohort study selected 3 303 singleton pregnant women who underwent regular prenatal examinations and genetic tests of thalassemia and were delivered at Maternal & Child Health Hospital of Guangxi Zhuang Autonomous Region from January 2019 to December 2023. According to the results of thalassemia gene testing, the women were divided into groups: those without thalassemia genes served as the control group (1 539 cases), and those with thalassemia genes (1 764 cases) were further divided based on genotype into the -α/αα group (326 cases), --/αα or -α/-α group (649 cases), point mutation α-thalassemia group (201 cases), β 0-thalassemia group (368 cases), β +-thalassemia group (91 cases), and α combined with β-thalassemia group (129 cases). Hemoglobin (Hb) and serum ferritin (SF) levels were measured in the first, second, and third trimester of pregnancy. Differences in anemia and iron reserves among the groups at different pregnancy stages were compared using repeated measures analysis of variance, LSD test, Kruskal-Wallis rank-sum test, and Bonferroni correction. Results:Compared to the first trimester, Hb levels decreased in the second and third trimester across all groups (LSD test, all P<0.05), and the severity of anemia increased (Bonferroni correction, all P<0.017). The severity of anemia varied among the groups at the same pregnancy stage ( Hfirst trimester=918.20, Hsecond trimester=1 224.50, Hthird trimester=980.19; all P<0.001), and Hb levels also differed ( Ffirst trimester=282.54, Fsecond trimester=352.31, Fthird trimester=239.02; all P<0.001). The β 0-thalassemia group had higher rates of moderate anemia in the first, second, and third trimester of pregnancy [38.6% (142/368), 85.3% (314/368), and 73.6% (271/368)] compared to other groups (Bonferroni correction, all P<0.002), and lower Hb levels [(102.1±8.9), (92.0±7.3), and (94.6±7.7) g/L] than other groups (LSD test, all P<0.05). As pregnancy progresses, SF levels in each group of pregnant women gradually decreased (LSD test, all P<0.05), and the degree of iron deficiency worsened (Bonferroni correction, all P<0.05). The iron deficiency rate in thalassemia pregnant women during the third trimester ranges from 21.5% (79/368) to 46.0% (150/326). The degree of iron deficiency varies among groups within the same gestational period ( Hfirst trimester=79.13, Hsecond trimester=203.98, Hthird trimester=130.55; all P<0.001), and SF levels also differ ( Ffirst trimester=17.28, Fsecond trimester=44.60, Fthird trimester=31.87; all P<0.001). Among them, the β 0-thalassemia group had the lowest iron deficiency rates in the second, and third trimesters [9.8% (36/368), and 21.5% (79/368)] (Bonferroni correction, all P<0.002). SF levels in the β 0-thalassemia and β +-thalassemia groups were higher than those in other groups during each gestational period (LSD test, all P<0.05). Conclusions:Pregnant women with thalassemia may experience varying degrees of iron deficiency during pregnancy, with the severity of iron deficiency and anemia increasing with gestational age. The degree of iron deficiency and anemia during pregnancy varies among pregnant women with different genotypes of thalassemia. Clinically, individualized management should be provided for pregnant women with thalassemia based on their genotypes, with dynamic monitoring of anemia and iron metabolism changes.

Kawasaki disease（KD）is an acute systemic vasculitis primarily affecting small- and medium-sized arteries in children，with widespread inflammation as the major pathological hallmark. A subset of patients with KD exhibit resistance to high-dose intravenous immunoglobulin（IVIG）therapy，which significantly increases the risk of developing severe cardiovascular complications，particularly coronary artery lesions（CAL）. Interferon gamma-inducible protein 10（IP-10），a chemokine，exerts its biological functions by binding to its specific receptor，chemokine receptor 3（CXCR3）. In the relevant research on KD，the association between IP-10 and IP-10 gene polymorphism with KD has garnered significant attention from both domestic and international researchers. This article reviews the recent research progress on the relationship between IP-10，its gene polymorphism and KD，with the aim of providing references for the pathogenesis，prevention，treatment and prognosis of KD.
