OBJECTIVE To investigate the clinical efficacy of integrating pharmacists into family health teams （FHTs） for long-term medication therapeutical management （MTM） in stroke patients， and empirically evaluate the service model. METHODS A pharmacist team， jointly established by clinical and community pharmacists from the Affiliated Suzhou Hospital of Nanjing Medical University （hereinafter referred to as “our hospital”）， developed a pharmacist-supported MTM model integrated into FHTs. Using a prospective randomized controlled design， 170 stroke patients discharged from our hospital （July 2022-December 2023） and enrolled in FHTs at Suzhou Runda Community Hospital were randomly divided into trial group （88 cases） and control group （82 cases） according to random number table. The control group received routine FHTs care （without pharmacist involvement in the team collaboration）， while the trial group xhz8405@126.com received 12-month MTM services supported by pharmacists via an information platform. These services specifically included innovative interventions such as personalized medication regimen optimization based on the MTM framework， dynamic medication adherence management， medication safety monitoring， a home medication assessment system， and distinctive service offerings. Outcomes of the 2 grousp were compared before and after intervention， involving medication adherence （adherence rate， adherence score）， compliance rates for stroke recurrence risk factors [blood pressure， low-density lipoprotein cholesterol （LDL-C）]， and incidence of adverse drug reactions （ADR）. RESULTS After 12 months， the trial group exhibited significantly higher medication adherence rates， improved adherence scores， higher compliance rates for blood pressure and LDL-C targets compared to the control group （P＜0.05）. The incidence of ADR in the trial group （4.55%） was significantly lower than that in the control group （8.11%）， though the difference was not statistically significant （P＞ 0.05）. CONCLUSIONS Pharmacist involvement in FHTs to deliver MTM services significantly enhances medication adherence and optimizes risk factor for stroke recurrence， offering practical evidence for advancing pharmaceutical care in chronic disease management under the family doctor system.

BACKGROUND: The contraction behaviors of cardiomyocytes (CMs), especially contraction synchrony, are crucial factors reflecting their maturity and response to drugs. A wider field of view helps to observe more pronounced synchrony differences, but the accompanied greater computational load, requiring more computing power or longer computational time. METHODS: We proposed a method that directly correlates variations in optical field brightness with cardiac tissue contraction status (CVB method), based on principles from physics and photometry, for rapid video analysis in wide field of view to obtain contraction parameters, such as period and contraction propagation direction and speed. RESULTS: Through video analysis of human induced pluripotent stem cell (hiPSC)-derived CMs labeled with green fluorescent protein (GFP) cultured on aligned and random nanofiber scaffolds, the CVB method was demonstrated to obtain contraction parameters and quantify the direction and speed of contraction within regions of interest (ROIs) in wide field of view. The CVB method required less computation time compared to one of the contour tracking methods, the LucasKanade (LK) optical flow method, and provided better stability and accuracy in the results. CONCLUSION This method has a smaller computational load, is less affected by motion blur and out-of-focus conditions, and provides a potential tool for accurate and rapid analysis of cardiac tissue contraction synchrony in wide field of view without the need for more powerful hardware.

ObjectiveTo investigate the general situation， dietary factors， and clinical features of patients with recurrent primary common bile duct stones， and to provide a basis for effective prevention of stone recurrence. MethodsA retrospective analysis was performed for 23 730 patients who underwent cholecystectomy due to cholelithiasis in Department of Hepatobiliary， Pancreatic and Spleen Surgery， Inner Mongolia People’s Hospital， from January 2013 to December 2023， and according to the presence or absence of recurrence of primary common bile duct stones after surgery， 334 patients were divided into recurrence group. The recurrence group was further analyzed based on sex in terms of recurrence rate， recurrence cycle， recurrence age， recurrence type， and general， disease， imaging， and dietary factors. The independent-samples t test was used for comparison of continuous data between two groups， the chi-square test was used for comparison of categorical data between two groups. ResultsThere were 334 cases of recurrence of primary bile duct stones after cholecystectomy， with a recurrence rate of 1.41%， and the highest frequency of recurrence cycle was observed in 10 years after surgery， with a significant difference in recurrence cycle between the male and female patients （t=5.238， P<0.001）. There was a significant difference in the recurrence rate of stones after surgery between the patients with simple gallstones and those with gallbladder and common bile duct stones at initial diagnosis （1.23% vs 2.76%， χ²=42.104， P<0.001）. The patients with recurrence aged >60 years accounted for the highest proportion in the whole population and in both male and female populations， and 92% were Han residents； 10% of the patients with recurrence had a family history of gallstones， and as for comorbidities， the patients with hypertension accounted for the highest proportion. Among the patients with recurrence， the patients with smoking or drinking accounted for 76.7% and 10.3%， respectively. As for body weight， 63.8% of the patients with recurrence had a normal body mass index （BMI）， and 23.2% of the patients were overweight； compared with body weight at the time of the first gallbladder surgery， a reduction in body weight was observed in 60.1% of the patients with recurrence， while an increase in body weight was observed in 22.9% of the patients with recurrence. There were significant differences between the male and female patients with recurrence in age composition， ethnicity， the type of place of residence， comorbidities， smoking， drinking， BMI， and the change in body weight （all P<0.001）. As for the type of stone recurrence， the ratio of multiple stones， solitary stones， and muddy stones was 74∶15∶11， and the stone size of <1 cm， 1-2 cm， and >2 cm accounted for about 40.5%， 48.8%， and 10.6%， respectively. As for the surgical procedure， the patients undergoing laparotomy accounted for 66.1%， and those undergoing laparoscopy accounted for 33.9%. The patients with various types of dyslipidemia accounted for a percentage of<30%. There were significant differences between the male and female patients with recurrence in the type of stones at initial onset， the type and size of stones， and surgical procedure （all P<0.001）. Imaging data showed that 4 patients had an abnormal structure of the bile duct， manifesting as long and curve cystic ducts， and 73.1% of the patients had common bile duct dilatation after surgery. The follow-up of dietary factors showed irregular diets in 55.8% of the patients with recurrence. As for the dietary structure， meat and staple food accounted for 43.8% and 37.8%， respectively， which showed a sex difference， with meat in male patients and staple food in female patients； 64.1% of the patients with recurrence had a high-salt and high-oil diet； 59.8% of the patients had changes in diet after the first surgery for stones， among whom 80% were able to have a regular diet， and the patients with a regular diet accounted for 92%. ConclusionThere is a relatively low recurrence rate of primary common bile duct stones in this area， and there is no sex difference. The peak of recurrence is 10 years after surgery， and recurrence of stones is mainly observed in the population aged >60 years. The analysis of dietary and clinical features can help doctors and patients to further understand the characteristics of the recurrence of primary common bile duct stones and provide a basis for subsequent targeted prevention.

Objective To investigate the efficacy of leaflet augmentation technique to repair the recurrent mitral valve (MV) regurgitation after mitral repair in children. Methods A retrospective analysis was conducted on the clinical data of children who underwent redo MV repair for recurrent regurgitation after initial MV repair, using a leaflet augmentation technique combined with a standardized repair strategy at Fuwai Hospital, Chinese Academy of Medical Sciences, from 2018 to 2022. The pathological features of the MV, key intraoperative procedures, and short- to mid-term follow-up outcomes were analyzed. Results A total of 24 patients (12 male, 12 female) were included, with a median age of 37.6 (range, 16.5–120.0) months. The mean interval from the initial surgery was (24.9±17.0) months. All children had severe mitral regurgitation preoperatively. The cardiopulmonary bypass time was (150.1±49.5) min, and the aortic cross-clamp time was (94.0±24.2) min. There were no early postoperative deaths. During a mean follow-up of (20.3±9.1) months, 3 (12.5%) patients developed moderate or severe mitral regurgitation (2 severe, 1 moderate). One (4.2%) patient died during follow-up, and one (4.2%) patient underwent a second MV reoperation. The left ventricular end-diastolic diameter was significantly reduced postoperatively compared to preoperatively [ (43.5±8.6) mm vs. (35.8±7.8)mm, P<0.001]. Conclusion The leaflet augmentation technique combined with a standardized repair strategy can achieve satisfactory short- to mid-term outcomes for the redo mitral repair after previous MV repair. It can be considered a safe and feasible technical option for cases with complex valvular lesions and severe pathological changes.

Background and Aims:Postoperative intra-abdominal infection(PIAI)is a common postoperative complication in abdominal surgery and a challenging issue worldwide,with a treatment failure rate of 68.3％and an in-hospital mortality rate as high as 40.8％.The key to managing this condition is early control of the infection source,debridement and adequate drainage.Delayed control of the infection source is an independent risk factor for predicting treatment failure.Many PIAI lesions are located deep within the abdominal cavity,lacking optimal routes for percutaneous drainage,and the risks and difficulties of reoperation are significant.Thus,controlling the infection source in PIAI is a difficult task.Here,the authors report the management of 4 PIAI patients treated with nephroscopic debridement and catheter irrigation and drainage via the sinus tract,aiming to provide clinical insights and references. Methods:The clinical data of 4 patients undergoing nephroscopic debridement,catheter irrigation and drainage for PIAI from October 2020 to September 2022 in the Department of Hepatobiliary and Pancreatic Surgery of the Second Affiliated Hospital of Guilin Medical University were retrospectively analyzed.Key techniques of nephroscopic management of PIAI were summarized and contextualized with relevant literature. Results:The 4 PIAI cases included a right-sided retroperitoneal abscess after catheter drainage for severe acute pancreatitis,a hepatic abscess at the liver raw surface after right hemihepatectomy,bile leakage and secondary duodenal fistula after laparoscopic choledocholithotomy and T-tube drainage,and a pancreatic abscess at the pancreatic raw surface after distal pancreatectomy with splenectomy.All patients underwent nephroscopic debridement and catheter irrigation and drainage via the sinus tract:guidewires were inserted into the drainage sinus tract,followed by a minimally invasive expansion drainage kit and nephroscopy;pus was irrigated out,and pus moss was clamped out with foreign body forceps under nephroscopy.Then,irrigation drainage tubes were placed under the guidance of the guidewire,and continuous irrigation and drainage were performed.The 4 patients underwent a total of 5 nephroscopic debridement and catheter irrigation and drainage procedures,with one case requiring two operations.The preoperative catheterization time ranged from 14 to 58 d,with an average of 38.4 d.One patient concurrently underwent choledochoscopy for stone extraction and biliary drainage via the T-tube sinus tract.The operative time ranged from 30 to 115 min,with an average of 67.4 min.Aside from one case of minor intraoperative bleeding,which stopped after injecting diluted norepinephrine solution into the sheath and blocking the sheath,there were no surgical complications in the other three cases.The postoperative drainage tube duration ranged from 7 to 30 d,with an average of 20.75 d.After treatment,all PIAI lesions disappeared,and no recurrence was observed during follow-up,which ranged from 16 to 40 months. Conclusion:Nephroscopic debridement and catheter irrigation and drainage via the sinus tract for PIAI is simple,feasible,and safe,allowing for direct visualization to avoid organ damage.It is effective in removing pus and necrotic tissue,replacing drainage tubes,and can be repeatedly performed with high efficiency and remarkable results.This method is particularly suitable for patients with postoperative abdominal drainage tube obstruction combined with encapsulated intra-abdominal fluid collections.

Two pediatric heart failure patients were treated with pulmonary artery banding(PAB)at Fuwai Hospital,from December 2021 to January 2022.In the first case,an 8-month-old patient presented with left ventricular non-compaction cardiomyopathy(LVNC),left ventricular systolic dysfunction,ventricular septal defect,and atrial septal defect.The second case was a 4-month-old patient with LVNC,left ventricular systolic dysfunction,and coarctation of the aorta.After PAB,the left ventricular function and shape of both patients were significantly improved,without serious surgery-related complications.In these individual cases of pediatric heart failure,pulmonary artery banding exhibited a more satisfactory efficacy and safety compared to pharmacological treatment,especially for those with unsatisfactory medication results.Future clinical data are needed to promote the rational and broader application of this therapeutic option for indicated patients.
