OBJECTIVE To evaluate the influence of pharmaceutical quality control on the efficiency and outcomes of standardized medication therapy management （MTM） services for patients with coronary heart disease by using Economic， Clinical and Humanistic Outcomes （ECHO） model. METHODS This study collected case data of coronary heart disease patients who received MTM services during January-March 2023 （pre-quality control implementation group， n＝96） and June-August 2023 （post-quality control implementation group， n＝164）. Using propensity score matching analysis， 80 patients were selected from each group. The study subsequently compared the economic， clinical， and humanistic outcome indicators of pharmaceutical services between the two matched groups. RESULTS There were no statistically significant differences in baseline data between the two groups after matching （P＞0.05）. Compared with pre-quality control implementation group， the daily treatment cost （16.26 yuan vs. 24.40 yuan， P＜0.001）， cost-effectiveness ratio [23.12 yuan/quality-adjusted life year （QALY） vs. 32.32 yuan/QALY， P＜0.001]， and the incidence of general adverse drug reactions （2.50% vs. 10.00%， P＝0.049） of post-quality control implementation group were decreased significantly； the utility value of the EuroQol Five-Dimensional Questionnaire （0.74± 0.06 vs. 0.71±0.07， P＝0.003）， the reduction in the number of medication related problems （1.0 vs. 0.5， P＜0.001）， the medication adherence score （[ 6.32±0.48） points vs. （6.10±0.37） points， P＝0.001]， and the satisfaction score （[ 92.56±1.52） points vs. （91.95±1.56） points， P＝0.013] all showed significant improvements. Neither group experienced serious adverse drug reactions. There was no statistically significant difference in the incidence of new adverse reactions between the two groups （1.25% vs. 3.75%， P＝0.310）. CONCLUSIONS Pharmaceutical quality control can improve the quality of pharmaceutical care， and the ECHO model can quantitatively evaluate the effect of MTM services， making pharmaceutical care better priced and more adaptable to social needs， thus being worthy of promotion.

Objective: To understand the trend of mortality and life loss of primary liver cancer (PLC) in Yuyao City from 2014 to 2023, so as to provide the basis for formulating comprehensive prevention and treatment strategies of PLC. Methods: The PLC mortality data of registered population in Yuyao City from 2014 to 2023 were collected from Ningbo Municipal Chronic Disease Surveillance System. Crude mortality of PLC was calculated, and standardized using the data from the Sixth National Population Census in 2010 (Chinese-standardized rate) and the Segi's world standard population in 1960 (world-standardized rate). The mortality characteristics of PLC among different genders and age groups were analyzed. The disease burden of PLC was assessed using potential years of life lost (PYLL), average years of life lost (AYLL), and potential years of life lost rate (PYLLR). The trends in PLC mortality and disease burden from 2014 to 2023 were analyzed using the average annual percent change (AAPC). Results: There were 2 072 PLC deaths in Yuyao City from 2014 to 2023, and the crude mortality was 24.81/100 000, the Chinese-standardized rate was 14.24/100 000, and world-standardized rate was 10.85/100 000, all showed a downward trend (AAPC=-5.874%, -9.053% and -9.147%, all P<0.05). The crude mortality in males was higher than that in female (35.93/100 000 vs. 14.02/100 000, P<0.05). The trends in crude mortality, Chinese-standardized rate, and world-standardized rate of PLC for males and females were consistent with those of the entire population. The youngest age at death from PLC was 9.42 years, and the oldest was 96.91 years. The average age at death increased from 64.34 years in 2014 to 69.81 years in 2023 (AAPC=0.965%, P<0.05). The crude mortality rate of PLC increased with age (P<0.05), reaching a peak at 94.61/100 000 in those aged ≥85 years. The PYLL of PLC was 17 018.00 person-years, the AYLL was 13.60 years/person, and the PYLLR was 2.89‰. From 2014 to 2023, both PYLL and PYLLR showed downward trends (AAPC=-10.543% and -9.789%, both P<0.05). Conclusions From 2014 to 2023, the mortality, PYLL, and PYLLR of PLC in Yuyao City all showed downward trends. Men and the elderly were key groups for the prevention and control of PLC.

BACKGROUND: The urban-rural disparities in overweight and obesity among children and adolescents are narrowing, and there is a need for long-term and updated data to explain this inequality, understand the underlying mechanisms, and identify priority groups for interventions. METHODS: We analyzed data from seven rounds of the Chinese National Survey on Students Constitution and Health (CNSSCH) conducted from 1985 to 2019, focusing on school-age children and adolescents aged 7-18 years. Joinpoint regression was used to identify inflection points (indicating a change in the trend) in the prevalence of overweight and obesity during the study period, stratified by urban/rural areas and sex. Annual percent change (APC), average annual percent change (AAPC), and 95% confidence interval (CI) were used to describe changes in the prevalence of overweight and obesity. Polynomial regression models were used to predict the prevalence of overweight and obesity among children and adolescents in 2025 and 2030, considering urban/rural areas, sex, and age groups. RESULTS: The prevalence of overweight and obesity in urban boys and girls showed an inflection point of 2000, with AAPC values of 10.09% (95% CI: 7.33-12.92%, t = 7.414, P <0.001) and 8.67% (95% CI: 6.10-11.30%, t = 6.809, P <0.001), respectively. The APC for urban boys decreased from 18.31% (95% CI: 4.72-33.67%, t = 5.926, P = 0.027) to 4.01% (95% CI: 1.33-6.75%, t = 6.486, P = 0.023), while the APC for urban girls decreased from 13.88% (95% CI: 1.82-27.38%, t = 4.994, P = 0.038) to 4.72% (95% CI: 1.43-8.12%, t = 6.215, P = 0.025). However, no inflection points were observed in the best-fit models for rural boys and girls during the period 1985-2019. The prevalence of overweight and obesity for both urban and rural boys is expected to converge at 35.76% by approximately 2027. A similar pattern is observed for urban and rural girls, with a prevalence of overweight and obesity reaching 20.86% in 2025. CONCLUSIONS The prevalence of overweight and obesity among Chinese children and adolescents has been steadily increasing from 1985 to 2019. A complete reversal in urban-rural prevalence is expected by 2027, with a higher prevalence of overweight and obesity in rural areas. Urgent action is needed to address health inequities and increase investments, particularly policies targeting rural children and adolescents.

Objective: To analyze the prevalence of comorbidity of spinal curvature abnormality and malnutrition among primary and secondary school students aged 10-18 years in Tianjin in 2023, so as to provide scientific basis for the combined prevention of common diseases and multiple diseases among students and the construction of school health system. Methods: In September to October 2023, 31 884 primary and secondary school students aged 10 to 18 years in Tianjin were selected using stratified cluster random sampling. Abnormal spinal curvature in children and adolescents was assessed by Sereening of Spinal Curvature Abnormality of Children and Adolescents, while stunting, wasting, overweight, and obesity were determined according to the Screening for Malnutrition among Schoolage Children and Adolescents and Screening for Overweight and Obesity among Schoolage Children and Adolescents. The χ2 test was used to compare betweengroup differences in coprevalence, and multiple Logistic regression models were used to analyze the risk of different comorbidity types in different clusters. Results: The coprevalence of spinal curvature abnormality and malnutrition among primary and secondary school students in Tianjin was 1.6%, which was higher for girls than boys (1.8%, 1.4%), higher (2.5%) for senior high schools than for junior high schools and elementary schools (2.0%, 0.5%), and higher in rural than in urban areas (2.1%, 1.1%) (χ2=9.45, 141.92, 46.94, P<0.05). Multiple Logistic regression models showed that junior high school girls had a higher risk of incorrect posture comorbid with stunting and wasting (OR=4.52, 95%CI=1.84-11.06) and incorrect posture comorbid with overweight and obesity (OR=2.67, 95%CI=1.74-4.10) than boys, and that scoliosis/sagittal spinal abnormality comorbid with stunting and wasting (OR=0.10, 95%CI=0.02-0.44) risk was lower than that of boys, senior high school girls had a lower risk of scoliosis/sagittal spinal abnormality comorbid with overweight and obesity (OR=0.27, 95%CI=0.11-0.66) (P<0.05). Conclusions The coprevalence of spinal curvature abnormality and malnutrition is specific among primary and secondary school students in Tianjin, and the comorbidity type varies by gender and education stage. There is a need to increase prevention and control of spinal curvature abnormalities in school health working, intensive screening of key populations, and timely intervention.

OBJECTIVE To explore the safety， effectiveness， and cost-effectiveness of elderly patients with sarcopenia receiving Shenling baizhu powder combined with nutrition and exercise intervention， providing a reference for rational clinical drug use. METHODS A total of 237 elderly sarcopenia patients were randomly assigned to an observation group （118 cases） and a control group （119 cases）. Both groups of patients received nutrition and exercise intervention； the observation group added Shenling baizhu powder （6 g each time， three times daily） on this basis. The safety， effectiveness， and cost-effectiveness of the two plans were compared after 3 months. RESULTS Both groups of patients completed the follow-up. Before intervention， no significant difference was observed in skeletal muscle index （SMI）， grip strength， and 6-minute walk test （6MWT） speed between the two groups （P＞0.05）. After intervention， the grip strength of the patients in the observation group was significantly greater than that of the control group （25.05 kg vs. 23.18 kg， P＜0.01）； the treatment response rate of sarcopenia， SMI， and 6MWT speed were higher than those of the control group， butthe differences were not statistically significant （P＞0.05）. The adverse reaction/event rate of the patients in the observation group was lower than that of the control group （14.41% vs. 16.81%， P＝0.611）， but the difference was not statistically significant. Compared with the control group’s plan， the cost of the observation group’s plan was higher （981.25 yuan vs. 913.94 yuan）， and the effect was better （effectiveness rate： 0.618 6 vs. 0.563 0）， with an incremental cost-effectiveness ratio of 1 210.61 yuan. The results of the sensitivity analysis were consistent with the cost-effectiveness analysis results. CONCLUSION Elderly patients with sarcopenia who receive Shenling baizhu powder combined with nutrition and exercise intervention can significantly strengthen grip strength without increasing the incidence of adverse reactions/events. Compared with the control group plan， the observation group needs to spend an additional 1 210.61 yuan for each additional effective patient with sarcopenia.

Objectives:To evaluate the valvular and cardiac function,cardiac reverse remodeling at 6-month after transcatheter edge-to-edge repair(TEER)for patients with functional and degenerative mitral valve regurgitation,and summarize the experience of echocardiography application. Methods:The clinical data of 93 patients with moderate to severe mitral regurgitation(MR)treated with TEER and completed 6-month follow-up in Yunnan Fuwai Cardiovascular Hospital from July 2022 to February 2023 were retrospectively analyzed.Patients were divided into functional mitral regurgitation(FMR)and degenerative mitral regurgitation(DMR)groups according to MR etiology.The valve characteristic parameters,as well as valvular function,chamber volume and cardiac functional parameters before and at 6 months after operation were compared.The key points of echocardiography application were summarized. Results:Among all patients,71 were FMR and 22 were DMR.There were differences in valve structure between the two groups.Mitral TEER were successfully accomplished and all patients completed 6-month follow-up.The key points of echocardiography application included:valve structure analysis,atrial septal puncture location,device delivery process monitoring and image optimization during clamping process.The mitral regurgitation grade and NYHA grade were significantly improved in all patients at 6 months after TEER(P<0.05),and the mean mitral valve pressure gradient was higher than that before operation(P<0.05).Left ventricular end-diastolic volume(LVEDV),left ventricular end-systolic volume(LVESV)and left atrial volume index in FMR group were significantly decreased(P<0.05),while left ventricular and left atrial volume in DMR group remained unchanged(P>0.05).There were no significant changes in left ventricular ejection fraction and left ventricular global strain in both groups during the observation period(P>0.05).The changes of LVEDV and LVESV before and after operation were more significant in FMR group than those in DMR group(P<0.05). Conclusions:Mitral TEER can reduce the degree of regurgitation and improve cardiac function in the early postoperative period for moderate and severe MR patients with different etiologies.There are differences in preoperative valve structure and postoperative cardiac reverse remodeling between FMR and DMR patients.Echocardiography is an important imaging technique for the evaluation and monitoring process before,during and post mitral TEER.

Persistent Müllerian duct syndrome(PMDS) is a rare disorder that arises from a lack of active anti-Müllerian hormone(AMH) or type Ⅱ AMH receptor(AMHR2) deficiency in males with a normal 46, XY chromosome karyotype.It presents that the external genitalia appears normally while the Müllerian duct structure(uterus, fallopian tubes, upper vagina) persists in the body.Common pathogenic factors are mutations in the AMH and AMHR2 genes, inherited in an autosomal recessive manner.This study reported two families with PMDS.The first patient was diagnosed with PMDS due to cryptorchidism in May 2019.Gene sequencing analysis revealed a new missense mutation(c.579G>T; p.W193C) and a splicing mutation(c.622-3C>A; splicing) in the AMHR2 gene.His father had the missense mutation(c.579G>T; p.W193C), and his mother had the splicing mutation(c.622-3C>A; splicing).The second patient was diagnosed with PMDS due to bilateral cryptorchidism, transverse testis ectopia in the right testicle in March 2023.Undegraded Müllerian tube derivatives were found between the two testicles, and serum AMH levels were very high(565.00 μg/L).Gene sequencing analysis reported that the AMHR2 gene had a new deletion mutation(c.835_837del; p.Leu279del).Both his father and mother had a deletion mutation(c.835_837del; p.Leu279del).This study reports two new AMHR2 gene mutations that expand the mutation sites of this rare disease.It is recommended to consider PMDS in the differential diagnosis of cryptorchidism, undergo surgery as early as possible, and treat Müllerian duct derivatives based on individual anatomical characteristics.

"State-target-cause-result"is a new clinical theory combining macroscopic and microscopic syndrome differentiation based on the holistic view of traditional Chinese medicine combined with Western medical research.The"inflammation-cancer transformation"of chronic pancreatitis is a complex pathological process that is associated with the interaction between the pancreas and various pathological factors and multiple objects,involving the imbalance of multiple homeostasis.The microscopic process of"inflammation-cancer transformation"in chronic pancreatitis is the"target,"whereas various factors that could induce its occurrence under chronic inflammatory conditions are the"state."The"inflammation-cancer transformation"of chronic pancreatitis is summarized as yin and yang imbalance,qi movement disorder,endogenous dampness,heat,blood stasis,and turbid phlegm stagnation,unresolved congestion resulting in deficiency caused by stagnation,intermingled deficiency and excess,and internal cancer toxin generation.This paper elucidates the pathogenesis and intervention strategies of the"inflammation-cancer transformation"of chronic pancreatitis from a macro perspective of"state,"focusing on reducing the impact of"state"imbalance on the"target"to establish a balanced pancreas-immune-microbiota state.The aim is to broaden the theory for exploring the mechanism and drug development related to chronic pancreatitis"inflammation-cancer transformation"in both traditional Chinese and Western medicine.

Objective:To evaluate the relationship between physical activity (PA) and postoperative delirium (POD) in elderly patients undergoing knee or hip arthroplasty.Methods:The study was conducted as part of the Perioperative Neurocognitive Impairment and Biomarkers Lifestyle Cohort, which was a nested case-control study. Medical records from elderly patients undergoing elective knee or hip arthroplasty under spinal-epidural anesthesia at Qingdao Municipal Hospital from August 2022 to August 2023 were collected. The patients were divided into a POD group ( n=89) and a non-POD group ( n=221) based on the occurrence of POD. Peripheral blood samples were collected before surgery, and the cerebrospinal fluid (CSF) 2 ml was extracted after successful puncture under spinal-epidural anesthesia for determination of the concentrations of amyloid-β 42 (Aβ 42), total tau protein (t-tau), and phosphorylated tau protein (p-tau) by enzyme-linked immunosorbent assay. Logistic regression was used to analyze the influencing factors of POD, and the mediation analysis was conducted to examine the mediating role of CSF biomarker in the relationship between PA and POD. Results:Logistic regression analysis showed that the increased concentration of CSF biomarkers Aβ 42 ( OR=0.997, P=0.006), elevated ratio of Aβ 42/t-tau ( OR=0.642, P=0.003), elevated ratio of Aβ 42/p-tau ratio ( OR=0.872, P=0.001) and PA ( OR=0.374, P=0.001) were protective factors for POD, while the elevated concentrations of t-tau ( OR=1.006, P=0.001) and p-tau ( OR=1.030, P=0.011) were risk factors for POD after adjusting for multi-confounders such as hypertension, diabetes, history of drinking, years of education and Mini-Mental State Examination score. The results of the mediation analysis showed that Aβ 42 (20%), t-tau (16%), Aβ 42/t-tau (23%) and Aβ 42/p-tau (28%) played mediating roles in the relationship between PA and POD. Conclusions:PA is a protective factor for POD in elderly patients undergoing knee or hip arthroplasty and CSF biomarkers may play a mediating role in the relationship between PA and POD.

Streptococcus parasuis(S.parasuis)is a close relative of S.suis and can cause meningi-tis,pneumonia or systemic symptoms in affected animals.In this paper,the dominant strain was i-solated from diseased pigs with pneumonia in Jilin,China,and the isolated strain was identified as S.parasuis by 16S rRNA,it was named WYF-8B.Resistance was tested by the susceptibility tablet diffusion method,and WYF-8B was resistant to bacitracin,sulfamethoxoprim,lincomycin,erythro-mycin,fosfamycin,azithromycin,penicillin,doxycycline,cotrimotrixazole,sulfamisoxazole,cipro-floxacin,enrofloxacin,tetracycline,benzoxacillin,gentamicin,efazolin,and ampicillin.It was highly sensitive to florfenicol,chloramphenicol.Iochemical identification revealed that WYF-8B could fer-ment salicylic acid,maltose,lactose,sucrose,oxaesin,and glucose;nonfermentable mannitol,urea,raffinose,xylose,arabinose,and sorbitol.Using the second-generation whole-genome sequencing technology to study the WYF-8B resistant genotype,it was found that it carried the macrolide anti-biotic resistance genes Mef(E)and ErmB;resistance genes pbp2b,pbp1a,and pbp2x to β-lactam antibiotics;resistance genes gyrA,parC,and grlB to fluoroquinolones;resistance genes ANT(6)-Ia,AAC(6')-Ie-APH(2')-Ia,ANT(9)-Ia,APH(3')-Ⅲa to aminoglycoside antibiotics;re-sistance groups lnuB,lmrC,lmrD against lincomide antibiotics;resistance gene tetM to tetracy-cline antibiotics;the resistance gene of bacitracin,bcrA.The results found that the resistance phe-notype matches the resistance genotype of the sequencing results.The study of WYF-8B virulence factors found that WYF-8B carried 13 virulence factors(pavA,fbp 54,clpP,cps 4,cps 4 I,wbtB,cps,sI,tufA,galE,hasC,groEL,wrbtL,wbbtF),which mainly acted to promote bacterial diffu-sion,transfer,settlement,antiphagocytosis and immune evasion.The results of drug sensitivity test provide a reference for the study of clinical medication of S.parasuis,and drug resistance pheno-type and virulence factors lay the foundation for the research and development of new drugs and vaccines.
