Objective Flexible ureteroscopic holmium laser lithotripsy for the treatment of calculi in caliceal diverticulum complicated with perirenal hematoma has a low incidence.This paper discusses the clinical features and preventive strategies of the disease. Case Presentation The patient was a 58-year-old male, admitted due to repeated left lower back pain for two months. CT scan indicated left calyceal diverticulum stones. Transurethral flexible ureteroscopic holmium laser lithotripsy was performed. A follow-up CT scan revealed a left perirenal hematoma and the stones had shifted to the perirenal area. Percutaneous nephrolithotripsy was then performed. Four weeks after surgery, CT scan showed that the left perirenal hematoma had absorbed well. Conclusion The risk of perirenal hematoma and stone displacement may occur during ureteroscopic holmium laser lithotripsy for calyceal diverticulum stones. The risk can be effectively reduced by negative suction sheath, reduction of intraoperative perfusion pressure, reasonable use of holmium laser, and control of related factors.

OBJECTIVE To evaluate the quality differences of Alpinia katsumadai from different habitats. METHODS High- performance liquid chromatography（HPLC） was used to establish the fingerprints of A. katsumadai from 18 batches of different habitats， and the quality of A. katsumadai from different habitats was comprehensively evaluated by similarity evaluation， cluster analysis （CA）， principal component analysis （PCA）， orthogonal partial least squares-discriminant analysis （OPLS-DA） and the content determination results of alpinetin， pinocembrin， cardamonin and alnustone in A. katsumadai. RESULTS The similarity of HPLC fingerprints for 18 batches of A. katsumadai was ＞0.9. Eleven common peaks were identified from the chromatogram， and four of them were specifically characterized. Both CA and PCA grouped 18 batches of A. katsumadai into 3 categories， extracting 2 principal components （the cumulative variance contribution rate reached 89.798%）. OPLS-DA identified 9 quality difference markers， namely the components corresponding to peaks 4， 9， 3， 2， 7 （pinocembrin）， 8 （cardamonin）， 6 （alpinetin）， 10 and 11 （alnustone）. The content of alpinetin， pinocembrin， cardamonin， and alnustone ranged from 4.507 1-11.579 7， 5.154 4-14.183 3， 5.109 5-13.588 3 and 4.494 6-11.277 2 mg/g， respectively. CONCLUSIONS The quality of A. katsumadai from different habitats is quite different， and the quality of A. katsumadai from Hainan is the best.

Objective To investigate the DSA imaging characteristics and efficacy of interventional treatment for post-pancreaticoduodenectomy hemorrhage(PPH),and to analyze the factors influencing recurrent bleeding following successful interventional hemostasis.Methods Clinical data of patients who underwent interventional treatment for PPH between January 2013 and December 2022 were retrospectively analyzed.All patients underwent DSA examination,and interventional therapy was the primary treatment option for patients with positive findings.Statistical analysis was performed on DSA angiography manifestations,bleeding sites,success rate of interventional treatment and hemostasis effectiveness.Univariate and multivariate logistic regression analysis were used to analyze the independent risk factors for rebleeding after interventional treatment for PPH.Results A total of 139 patients with PPH were included in this study.All 139 patients underwent DSA examination,with a positive rate of 82.01％(114/139)in the first examination.Major angiographic manifestations included contrast agent extravasation,pseudoaneurysm,and disrupted vascular architecture;bleeding sites included gastroduodenal artery in 45 cases(39.47％),hepatic artery in 22 cases(19.30％),and superior mesenteric artery in 32 cases(28.07％).107 patients underwent interventional treatment(81 embolization and 26 stenting),with a success rate of 91.59％(98/107).The independent risk factors for recurrent bleeding after interventional treatment in patients with PPH included preoperative bleeding(P＜0.001)and pancreatic fistula(P=0.041).Conclusion Interventional procedures for PPH can be efficient in diagnosis and treatment,with a high success rate and effective hemostasis.However,it should be noted that some patients remain at risk of recurrent bleeding after successful interventional hemostasis.

Abstract Breastfeeding has an irreplaceable effect on the growth and development of premature infants and the reduction of complications during hospitalization. In recent years, with the opening of China′s birth policy, the incidence of premature babies has increased, and the corresponding complications have also gradually increased. Breast milk not only carries a rich supply of nutrients, including rich proteins, lipids, sugars to support the normal growth and development of infants, but also contains a large number of immunoglobulins, hormones and other bioactive substances to promote the improvement of body immune function and the development of nervous system. In recent years, many studies have been carried out on the current situation of breast milk operation in breast milk bank, the collection and influencing factors of breast milk, the strategies of breast milk enrichment and its effects on the growth and development of premature infants and complications. Therefore, breast-feeding and intensive breast-feeding can effectively promote the growth and development of premature infants, and reduce the occurrence of complications.

OBJECTIVE To observe the clinical efficacy of donafenib combined with programmed death-1 （PD-1） inhibitors and vascular intervention therapy in the treatment of unresectable hepatocellular carcinoma （HCC）. METHODS This retrospective study included 165 patients with unresectable HCC who were treated at the Fourth and First Affiliated Hospitals of Soochow University between June 2022 and March 2023. Among them， 89 patients received PD-1 inhibitors （tislelizumab or sintilimab， similarly hereinafter） plus vascular intervention （control group） and 76 patients received donafenib in combination with PD-1 inhibitors and vascular intervention （observation group）. Short-term efficacy （3 months after treatment）， long-term efficacy （2 years after treatment）， the levels of liver function indexes [serum alanine amino-transferase （ALT）， aspartate transferase （AST）， and total bilirubin （TBil）] and tumor biomarkers [alpha fetoprotein （AFP）， carcinoembryonic antigen （CEA）， carbohydrate antigen 19-9 （CA19-9）， and des-gamma-carboxy prothrombin （DCP）] before treatment and after 3 months of treatment， as well as the occurrence of adverse drug reaction （ADR） during treatment， were compared between the two groups. In addition， overall response rate （ORR） stratified by PD-1 inhibitor type was analyzed. RESULTS After treatment， the ORR was significantly higher in the observation group than in the control group （P＜0.05）； although the disease control rate was higher in the observation group compared to the control group， the difference was not statistically significant （P＞0.05）. The median overall survival of patients in the observation group was 16.9 months [95% confidence interval （CI）： 14.2 to 19.1 months]， which was significantly longer than that in the control group （12.4 months， 95%CI： 10.1 to 15.3 months） （P＜0.05）. Subgroup analysis result indicated that therapeutic advantage was consistent across both sintilimab and tislelizumab subgroups， with no significant heterogeneity （P＞0.1， I 2＜0.001%）. Before treatment， there were no significant differences in liver function indexes or tumor marker levels between 2 groups （P＞0.05）. After treatment， both groups showed significant declines in these indicators compared with baseline （P＜0.05）， with greater reductions observed in the observation group （P＜0.05）. There were no statistically significant differences in overall incidence of ADR and grade ≥3 ADRs between the two groups （P＞0.05）. CONCLUSIONS For patients with unresectable HCC， the combination of donafenib， PD-1 inhibitors and vascular intervention therapy may achieve superior clinical outcomes without increasing the risk of treatment-related ADR.

Objective:To analyze the efficacy of transjugular intrahepatic portosystemic shunt (TIPS) combined with main splenic artery embolization in the treatment of patients with portal hypertension upper gastrointestinal bleeding complicated with extensive portal vein thrombosis (PVT).Methods:This study was a prospective, single-center, open-label, single-arm clinical trial. In the first phase, 81 patients with portal hypertension upper gastrointestinal bleeding who were admitted to Beijing Shijitan Hospital, Capital Medical University from January 2018 to December 2018 were consecutively enrolled, including 57 males and 24 females, with the age of (51.3±10.4) years. During TIPS surgery, the pressure of the portal vein before and after the balloon blocking the splenic artery was measured to clarify the contribution of the splenic artery to portal hypertension. In the second stage, from January 2019 to December 2022, 104 patients with portal hypertension upper gastrointestinal bleeding complicated with extensive PVT were re-enrolled, including 71 males and 33 females, with the age of (50.9±12.5) years. TIPS combined with main splenic artery embolization was performed, and portal vein pressure was measured before and after embolization. Follow up on the postoperative esophageal and gastric varices of the patients in the second stage.Results:The portal vein pressures before and after the first stage of balloon occlusion of the splenic artery were (35.2±8.4) mmHg (1 mmHg=0.133 kPa) and (24.2±6.3) mmHg, respectively. The pressure after occlusion was lower than that before occlusion, and the difference was statistically significant ( t=10.54, P<0.001). The portal vein pressures before and after the second stage embolization were (36.1±9.5) mmHg and (21.1±4.7) mmHg respectively. The pressure after embolization was lower than that before embolization, and the difference was statistically significant ( t=13.47, P<0.001). In the second stage, among the 104 patients, the proportion of those whose varicose veins disappeared or improved 6 months after the operation was 43.3%(45/104) and 51.0%(53/104), respectively. There were no patients with aggravation or rebleeding due to rupture. One year later, 8 patients (7.7%) had aggravated or ruptured esophageal and gastric varices with bleeding. Two years later, 12 patients (11.5%) had aggravated or bleeding. Conclusion:TIPS combined with main splenic artery embolization can effectively reduce the portal vein pressure in patients with portal hypertension upper gastrointestinal bleeding complicated with extensive PVT, improve the degree of esophageal and gastric varices, and reduce the risk of gastrointestinal bleeding.

Objective:To explore the effectiveness of generative artificial intelligence (GAI) -empowered interprofessional collaborative learning model in nursing psychology practical teaching for undergraduate nursing students.Methods:From November to December 2024, 109 second-year nursing students from the Xiangya School of Nursing, Central South University were selected as research subjects using convenience sampling. Two classes were randomly divided into an experimental group (55 students) and a control group (54 students) using a random draw method. Control group received a traditional teaching model based primarily on case discussion and scenario simulation teaching, while experimental group used the GAI-empowered interprofessional collaborative learning model on the basis of control group. The teaching effectiveness was evaluated using the Psychological Nursing Practice Competency Assessment Scale, Caring Ability Inventory (CAI), Readiness for Interprofessional Learning Scale (RIPLS), and Satisfaction Survey Questionnaire.Results:After teaching, experimental group's practical course assessment scores, CAI total scores, and scores in each dimension were all higher than those of control group, with statistically significant differences ( P<0.01). The RIPLS score of nursing students in experimental group after teaching was higher than that before teaching, and the difference was statistically significant ( P<0.01). 90.9% of nursing students supported the introduction of GAI into the classroom, and 90.9% of nursing students recognized the auxiliary role of GAI in achieving learning objectives, and the teaching satisfaction was 96.4%. Conclusions:This study validates the effectiveness of GAI-empowered interprofessional collaborative learning model in nursing psychology practical teaching for undergraduate nursing students, providing new ideas for nursing education reform.

BACKGROUND:Cervical instability is a common orthopedic disease in young and middle-aged people,and is the early manifestation of cervical spondylosis,which has a great impact on the quality of life of patients.Therefore,early diagnosis of cervical instability to implement early intervention has positive clinical and social significance.OBJECTIVE:The clinical prediction model of cervical instability in young and middle-aged people was constructed based on machine learning to realize early screening of cervical instability in young and middle-aged people before X-ray examination.METHODS:From September 2022 to October 2023,155 young and middle-aged adults with cervical instability and 88 with non-cervical instability recruited through recruitment advertisements and spinal department outpatient of Wangjing Hospital,China Academy of Chinese Medical Sciences were selected as research subjects.The research subjects'general information,living and working habits,discomfort symptoms,visual analog scale score,Neck Disability Index,and 36-ltem Short Form Health Survey were collected on site based on questionnaires.The above information was used as predictive factors.After screening,six machine learning algorithms of Support Vector Machine,LightGBM,RandomForest,Logistic,AdaBoost,and XGBClassifier were used to train the model by ten-fold cross-validation method,and the clinical prediction model of cervical instability was constructed.Area under the curve was used as the main evaluation index.Univariate analysis was performed on the predictors,and SHAP method was used to rank the importance of the predictors.Correlation heat maps were used to show the degree of linear correlation between the predictors and the cervical instability.RESULTS AND CONCLUSION:(1)Among the six machine learning models,RandomForest model was chosen as the final prediction model,including nine predictors,such as age,body mass index,neck circumference/neck length,visual analog scale score,Neck Disability Index,bodily pain,general health,vitality,and mental health,area under the curve=0.725 4,and the calibration degree was good.It could be used as a reference tool for early screening of cervical instability in young and middle-aged people.(2)There were significant differences in age,visual analog scale score,Neck Disability Index,bodily pain,general health,and vitality between the two groups(P＜0.05).(3)The order of importance of predictors was age,Neck Disability Index,visual analog scale score,general health,body mass index,vitality,bodily pain,neck circumference/neck length,mental health,among which age,visual analog scale score,Neck Disability Index were positively correlated with cervical instability,while general health,body mass index,vitality,bodily pain,neck circumference/neck length,and mental health were negatively correlated with cervical instability.

Objective: To analyze the changes in homologous immunity after RhCE-matched transfusion in positive patients with RhCE blood group antibodies, and to provide precise transfusion strategies for chronic anemia patients. Methods: Patients with chronic anemia in our hospital from January 2020 to March 2024 (continuously receiving blood transfusions for more than 6 months) were enrolled, and 63 cases of unexpected antibody screening positive and identified as RhCE blood group antibodies were selected as the research subjects. The changes in unexpected antibody yield rate after ABO and RhCcDEe isotype blood transfusion were observed. Patients with MNS, Kidd, or Lewis blood group antibodies were screened for corresponding negative donors using monoclonal antibodies for extended typing transfusion based on RhCcEe typing, and the changes in unexpected antibody yield rate after transfusion were observed. Blood group genotyping was performed when serological techniques failed to resolve discrepancies or detect abnormal antigen expression. Results: After RhCcDEe-matched transfusions, RhCE antibodies disappeared in 62 patients, while 1 patient developed anti-Ce. The latter did not develop blood type isotype immunity after receiving RhccEE donor blood. Among the 62 patients, 9 developed unexpected antibodies against other systems: anti-M (4 cases), anti-Mur (2), anti-S (1), anti-Jka (1), and anti-Lea (1). No additional alloimmunization occurred after extended antigen-matched transfusions. A patient with serologically weak e phenotype was genotyped as DCe/DcE, with gene sequencing revealing an 827C>A mutation in exon 6 of the RHCE gene, forming the RHCE 01.31 allele. Conclusion: Precise transfusion strategies incorporating RhCE, MNS, Kidd, and Lewis blood group antigen typing can reduce the probability of blood group homologous immunity. RhCE complex antibodies and RhCE variants pose difficulties for clinical RhCE typing transfusion, which can be addressed through cross-matching and genetic analysis.

OBJECTIVE: The self-defined multidisciplinary (endocrinology, vascular surgery, and orthopedics) scoring system (EMO scoring system for short) was designed. The feasibility of the EMO scoring system to guide the proximal tibial transverse transport (TTT) for diabetic foot wounds was preliminarily explored. METHODS: Based on the current commonly used clinical criteria for diabetic foot judgment, expert consensus, guidelines, and related research progress in the treatment of diabetic foot wounds, combined with clinical experience, a set of EMO scoring systems including endocrinology, vascular surgery, and orthopedics was formulated. The criteria for selecting conservative treatment, TTT after baseline improvement, and TTT based on scoring results was proposed. A total of 56 patients with diabetic foot wounds who were admitted between September 2017 and July 2022 and met the selection criteria was taken as the study subjects. Among them, 28 patients were treated with TTT and 28 patients were treated conservatively. The patients were graded according to the EMO scoring system, the corresponding treatment methods were selected, and the actual treatment methods and results of the patients were compared. RESULTS: The EMO scoring system was formed through literature retrieval and clinical experiences. The system included three criteria, namely endocrinology (E), macrovascular disease (M), and orthopedics (O), which were divided into multiple subtypes according to the relevant evaluation items, and finally the diabetic foot wound was divided into 8 types, which correspondingly selected TTT, TTT after baseline improvement, and conservative treatment. All 56 patients were followed up 12 months after treatment. Among them, the wound healing rate of the TTT group was 85.71% (24/28), which was higher than that of the conservative treatment group [53.57% (15/28)]. At 12 week after treatment, CT angiography showed that there were more small blood vessels in the wound and ipsilateral limb in TTT group than in the conservative treatment group. Based on the EMO scoring system, 14 of the 56 patients needed conservative treatment, 29 patients needed TTT, and 13 patients needed TTT after baseline improvement. Compared with the clinical data of the patients, the wound healing rate of the patients judged to be TTT was 75.86% (22/29), of which 21 cases were actually treated with TTT, and the healing rate was 90.48%; 8 patients were treated conservatively, and the healing rate was 37.50%. The wound healing rate of the patients judged to be conservative treatment was 92.86% (13/14), of which 1 case was actually treated with TTT, and the healing rate was 100%; 13 cases were treated conservatively, and the healing rate was 92.31%; 1 case experienced minor amputation. The wound healing rate of the patients judged to TTT after baseline improvement was only 30.77% (4/13), of which 6 cases were actually treated with TTT, and the healing rate was 66.67%; 7 cases were treated conservatively, and the healing rate was 0. CONCLUSION EMO scoring system can comprehensively evaluate the diabetic foot wounds, and make personalized judgment on whether TTT treatment is feasible, so as to improve the level of diabetic foot wound treatment and the prognosis of patients.
