Procurement constitutes a cornerstone of daily operations in public hospitals,involving medical equipment,medical materials,pharmaceuticals,infrastructure projects,office supplies,and service-oriented projects.The responsibility for procurement used to rest on various functional departments overseeing business management,a situation that often led to a lack of transparency and standardization due to decisions made by a single department or a few key cadres.To standardize procurement practices,the national policy has introduced a"procurement"and"management"separation model.In public hospitals,pro-curement includes two main aspects:"procurement"entails the actual execution of purchasing activities,including market re-search,price negotiation,tender document formulation,and contract signing;and"management"involves the preliminary re-search,budgeting and project initiation,installation and commissioning,inventory acceptance,maintenance quality control,and usage management of procured items.The separation of"procurement"and"management"is an important part of the procure-ment management unit in the modern hospital administration.This process-based division ensures the functional distinction be-tween procurement and management,fostering interdepartmental collaboration and mutual oversight,thereby mitigating procure-ment integrity while safeguarding procurement quality.

Objective:To investigate the clinicopathologic features and molecular genetics characteristics of sinonasal tract mucosal malignant melanomas(STMMMs)in elderly patients.Methods:The clinicopathological features, immunohistochemical features and BRAF, C-KIT, NRAS mutations of STMMM in ten elderly patients were retrospectively analyzed.Results:Among the 10 patients, 5 were female and 5 were male.The patients were aged 65-81 years, with an average age of(72.5 ± 8.5)years.The lesions in 7 cases were located in the nasal cavity and paranasal sinuses, and in the other 3 cases were located in the nasopharynx.The morphologies of tumor cells under microscope was complex and diverse, showing plasma cell-like, rhabdomyoblast-like, small cell-like, epithelial-like, and spindle cell-like morphologies.Immunohistochemically, HMB-45 and S-100 were generally positive in 10 cases, and the positive rate of Melan A was 70.0%.The genes detection data showed no mutations in BRAF or NRAS genes in all the 10 cases, while C-KIT exon 11 c. 1666_1667insA mutation was found in one case, and the remaining 9 cases were wild-type for C-KIT.All the 10 cases were followed up for 4~50 months.Three cases survived so far.Conclusions:STMMM in elderly patients are rare and easy to be misdiagnosed.Immunohistochemistry and genetic testing provide guidance for accurate diagnosis and targeted therapy.

Long non-coding RNA (lncRNA) contains rich information and functions. The research on Traditional Chinese Medicine (TCM) targeting lncRNA mainly involves tumors, cardiovascular diseases, endocrine and metabolic related diseases, osteoporosis and other diseases, which are used to explore the mechanism of TCM and the differetiation of TCM syndromes or constitution, etc. LncRNA has important application prospects in the field of TCM. The study of lncRNA may provide new ways and technical methods for the research of modern TCM.

Kidney cancer usually requires multidisciplinary individualized treatments. No matter what kind of treatment, drugs are essential. According to the "six-step process" (prescription legitimacy review, patient basic information evaluation review, treatment protocol review, organ function and laboratory index review, pretreatment review, and unconventional prescription review) in prescription review proposed by the anti-tumor drug prescription review expert group and referring to domestic and foreign kidney cancer guidelines and drug instructions in recent years, this consensus selects 9 targeted drugs and 4 immunotherapeutic drugs that are currently commonly used in China and elaborates the key review points in patient basic information evaluation review, treatment protocol review, and organ function and laboratory index review of kidney cancer drug treatment, in order to provide reference for clinical front-line pharmacists to review prescriptions of kidney cancer patients and promote rational drug use in clinic.

With the continuous improvement of modern medical technology, medical practice has become more and more procedural. The medical process is often dominated by doctors, while the value orientation of patients is often ignored, lacking effective communication between doctors and patients. In response to this phenomenon, Charon R proposed the concept of narrative medicine, which has been recognized by all walks of life. In recent years, the value of medical humanism has attracted more attention, and the research on narrative medicine at home and abroad is increasing gradually. But at present, most of the research on narrative medicine is in terms of theory, lacking clinical research. How to make narrative medicine applied in the real world is the focus of current research. Following the concept of narrative medicine, and taking the study on doctor-patient parallel medical record to evaluate the real clinical efficacy of traditional Chinese medicine(TCM) and Western medicine(WM) in the treatment of digestive diseases as an example, this study is to explore the design contents and key points of the clinical trial scheme of doctor-patient co-construction of TCM and WM under narrative medicine, and discuss the activity form and clinical efficacy evaluation method under narrative medicine. Clinical trial design includes four aspects: medicine, ethics, statistics and trial management. This study explored the design of the doctor-patient co-construction clinical trial scheme under narrative medicine from both theoretical and practical aspects, providing reference for the design and research of future doctor-patient co-construction scheme, and expecting to establish a better efficacy evaluation method of TCM and WM.

Objective:To examine the association of abdominal obesity assessed by waist circumference (WC) with carotid intima-media thickness (cIMT) in children.Methods:The study participants were from the "Huantai Childhood Cardiovascular Health Cohort Study" conducted in Huantai County, Zibo City, Shandong Province. A convenient cluster sampling method was used to select a primary school in Huantai County to conduct the baseline survey from November 2017 to January 2018. A total of 1 515 children aged 6-11 years old were included. The first follow-up survey was conducted from November to December 2019, and a total of 981 children aged 8-13 years old were finally included after exclusion of those with high cIMT at baseline. Questionnaire survey, physical examination and ultrasonic examination were used to collect general demographic characteristics, WC and cIMT information. According to the status of WC at baseline, the participants were divided into normal WC group and abdominal obesity group. Covariance analysis was used to compare the cIMT levels of children between normal WC group and abdominal obesity group. Multivariable logistic regression models were used to evaluate the association between baseline abdominal obesity and high cIMT during the follow-up.Results:The age of 981 children was (8.5±1.5) years at the baseline. The follow-up age was (10.5±1.5) years, and 520 boys accounted for 53.0%. The cIMT of children in the abdominal obesity group was 0.54 mm, which was higher than that in the normal WC group (0.51 mm) ( P<0.001). Similarly, the prevalence of high cIMT in children with abdominal obesity (23.9%) was higher than that of normal WC group (3.9%) ( P<0.001). After adjusting for potential covariates at the baseline and during the follow-up period, compared with the normal WC group, abdominal obesity was significantly associated with high cIMT ( OR=5.78, 95% CI:3.43-9.74). Conclusion:The abdominal obesity in children could increase the risk of high cIMT.

This systematic review aims to evaluate the efficacy and safety of Wenxin Granules in the treatment of chronic heart failure with atrial fibrillation. Databases,such as CNKI,Wan Fang Date,VIP,PubMed,Cochrane Library,were electronically retrieved for relevant randomized controlled trials of Wenxin Granules in the treatment of chronic heart failure with atrial fibrillation. Two researchers independently screened out the literatures,extracted data according to the inclusion criteria,and conducted a quality assessment by the risk bias assessment tool in the Cochrane evaluation manual. Cochrane systematic evaluation software Rev Man 5. 3 was used for data analysis. Totally 11 randomized controlled trials,including 941 subjects. The intervention measures were the conventional treatment recommended by the guidelines combined with Wenxin Granules; and the control measures were the conventional treatment recommended by the guidelines alone. The results showed that compared with conventional treatment alone,Wenxin Granules combined with conventional treatment can better reduce the BNP level in patients with heart failure with atrial fibrillation( MD =-258. 18,95% CI[-464. 06,-52. 30],P= 0. 01) or NT-proBNP level,better improve left ventricular ejection fraction( MD = 6. 72,95%CI[4. 61,8. 84],P<0. 000 01),I~2= 65%,And the ventricular rate decreased more significantly( MD =-11. 66,95% CI[-15. 79,-7. 54],P<0. 000 01),and the cardiac function was improved more efficiently( RR = 1. 20,95%CI [1. 11,1. 31],P<0. 000 1),I~2= 23%.In conclusion,compared with the single administration of conventional Western medicine,the combined administration of Wenxin Granules has better effects in reducing the level of BNP or NT-proBNP,slowing down the ventricular rate,and improving the left ventricular ejection fraction,with fewer adverse reactions. However,due to the small sample size and the low quality of literatures included in this systematic review,it is shall be carefully applied in clinic. More rigorous randomized controlled trials shall be conducted to determine the efficacy of Wenxin Granules in improving cardiac function in the treatment of chronic heart failure with atrial fibrillation.
