ObjectiveTo explore the typical syndromes and their characteristic of symptoms and signs with high diagnostic value in patients with metabolic syndrome （MS）. MethodsTraditional Chinese medicine （TCM） diagnostic information was collected from 135 MS patients. Syndrome element differentiation and latent class analysis （LCA） were applied to identify the major TCM syndromes in MS patients. Symptoms were analyzed based on the differentiated syndromes， and a binary logistic regression model was constructed to determine symptoms and signs with high diagnostic value. ResultsA total of 135 MS patients were included， involving 163 symptoms and signs with a total frequency of 1749； twenty-three syndrome elements were extracted， 367 times frequency in total， among which 8 syndrome elements occurred ≥10 times with 323 frequencies （88.01% of the total）. These included location-related elements such as kidney （48 times）， spleen （14 times）， and stomach （14 times）， and nature-related elements such as phlegm （71 times）， yin deficiency （64 times）， dampness （57 times）， heat （42 times）， and qi deficiency （13 times）. Based on LCA， the 135 patients were categorized into two groups distinguished by the syndrome elements of dampness and phlegm， forming the "phlegm-dampness syndrome" as the major syndrome type. Nine high-frequency symptoms and signs associated with the phlegm-dampness syndrome were identified，i.e. obesity （39 times）， greasy coating （38 times）， slippery pulse （33 times）， white coating （31 times）， preference for fatty and heavy foods （30 times）， excessive urination （30 times）， fatigue and lack of strength （29 times）， wiry pulse （25 times）， and dark red tongue （25 times）. A binary logistic regression model was constructed combining these nine symptoms and signs with the LCA classification results， ultimately identifying obesity， greasy coating， fatigue and lack of strength， and white coating as independent factors associated with the phlegm-dampness syndrome in MS patients （P＜0.05）. ConclusionThe major TCM syndrome in MS patients is phlegm-dampness syndrome， and obesity， greasy coating， fatigue and lack of strength， and white coating are the typical symptoms and signs for diagnosing phlegm-dampness syndrome in MS patients.

OBJECTIVE To summarize the current status of position training for clinical pharmacists in China and provide references for the continuous optimization of such training programs. METHODS SinoMed， CNKI，VIP and Wanfang Data were electronically searched to collect position training of clinical pharmacists studies from the inception until November 5th 2024. After data extraction and quality evaluation， descriptive analysis was performed on the results of the included studies. RESULTS & A total of 68 pieces of relevant literature were included in the study. Among them， 50 studies reported on training content， 49 involved the allocation of teaching resources in the bases， 48 addressed training methods， and 39 focused on training evaluation； only 2 studies mentioned faculty development. There were notable variations in the clinical pharmacist training programs across different bases， particularly in the allocation of teaching resources， such as the composition of the teaching team and the utilization of auxiliary teaching tools. Additionally， differences existed in training approaches， such as those employing a single method versus a blended approach. Conversely， the core training content of each base generally revolved around clinical pharmacy practice， demonstrating a degree of consistency. Moreover， the overall emphasis on teacher training and assessment tended to be obviously insufficient. Each base can focus on enhancing the competence of clinical pharmacists by allocating teaching resources， selecting training methods， improving training content， and using evaluation tools， to further enhance the quality of clinical pharmacist training.

OBJECTIVES: To investigate the characteristics and clinical significance of anorectal manometry measurements in children with tethered cord syndrome (TCS) before and after surgery. METHODS: A retrospective study was conducted on 44 children with TCS treated at the Children's Hospital of Zhejiang University School of Medicine from January 2022 to September 2023. These patients were divided into effective subgroup (n=34) and non-effective subgroup (n=10) based on postoperative symptom improvement. Additionally, 34 children with functional constipation were selected as a control group. Baseline data and manometry measurements were compared between the preoperative TCS group and the control group, as well as between the non-effective and effective subgroups. RESULTS: The TCS group had lower short contraction time and defecation relaxation rate compared to the control group (P<0.05), while defecation residual pressure and maximum rectal tolerable threshold were higher than the control group (P<0.05). The length of the anal canal in the high-pressure zone in the effective subgroup was greater postoperatively than preoperatively (P<0.05), and the initial rectal sensation threshold decreased postoperatively (P<0.05). The non-effective subgroup had lower preoperative maximum rectal expulsion pressure compared to the effective subgroup (P<0.05). Postoperative rectal anal inhibition reflex values in the effective subgroup were higher than those in the non-effective subgroup (P<0.05). CONCLUSIONS There are some differences in anorectal dynamics between children with TCS and those with functional constipation. Maximum rectal expulsion pressure may be a key predictor of surgical outcomes. Surgery can alter certain defecation functions in some children.

Objective:To investigate the major considerations of domestic orthopaedic trauma surgeons in China when they diagnose and treat Mason type Ⅱ radial head fractures.Methods:A questionnaire survey was conducted from January 15, 2022 to January 16, 2022 using the convenience sampling method among domestic orthopedic trauma surgeons in China. The survey covered the surgeons' basic information, evaluation of Mason type Ⅱ radial head fractures, treatment preferences, and surgical indications recognized.Results:The present survey retrieved 474 eligible questionnaires. 358 surgeons (75.5%, 358/474) believed that the Morrey modified classification for Mason type Ⅱ radial head fracture could properly guide their diagnosis and treatment. 460 surgeons (97.0%, 460/474) believed that diagnosis of the fracture should be based on a combination of elbow X-ray and elbow CT examinations. Young age (80.2%, 380/474), dominant side involvement (66.2%, 314/474), concomitant ipsilateral upper limb injury (78.7%, 373/474), large fracture displacement (67.7%, 321/474), separation of fracture fragments from the main bone (91.6%, 434/474), and fracture involvement area >30% (81.6%, 387/474) were the main factors considered by the orthopedic trauma surgeons when they chose surgical treatment. Large fracture displacement (71.7%, 340/474), especially large articular steps (83.5%, 443/474), separation of fracture fragments from the main bone (75.9%, 360/474), and limited forearm rotation or joint clicking (82.7%, 392/474) found during physical examination were recognized as surgical indications for Mason type Ⅱ fracture by orthopedic trauma surgeons.Conclusion:Domestic orthopedic trauma surgeons in China prefer surgical treatment for Mason type Ⅱ radial head fractures with loss of cortical contact and large displacement, especially large articular steps.

Objective:To investigate the current status and developing trends of study of adult radial head fracture and its treatment.Methods:The literature related to radial head fracture from January 2010 to September 2022 was reviewed through Web of science database. A bibliometric method and visualization software were used to study all the data collected and the 100 most-cited studies related to the treatment of radial head fracture to understand the research status, related cooperation, research trends and research hotspots in the field of adult radial head fracture.Results:A total of 387 studies were included, with a citation frequency of 4,982 times, an average citation frequency of 12.9 times for each study, and an H index of 36. The most studies were published in 2020 (38 studies). The citation frequency increased year by year, reaching the highest (783 times) in 2019. For the 100 most-cited studies, the citation frequency was 2,235 times, and the average citation frequency was 22.4 times for each study. The United States (100 studies), Harvard University (30 studies), Journal of Shoulder and Elbow Surgery (69 studies), and Ring D (19 studies) were, respectively, the most contributing country/region, institution, journal, and author. The country/region, institution, and author that participated the most in the collaboration were, respectively, the United States, Amphia Hospital, and Eygendaal D. Radial head fractures of Mason types Ⅱ and Ⅲ and combined with other elbow fractures and dislocations have attracted the intense attention since 2010. The current research hotspots are combined injuries and radial head prosthesis. Conclusion:Analysis of the bibliometric characteristics of the literature related to adult radial head fracture since 2010 displays the current research status and research hotspots to help following researchers to fully understand the historical development and recent hotspots in the field of adult radial head fracture.

Objective:To evaluate the impact of self-crosslinked hyaluronic acid (SCH) gel on endometrium recovery after artificial abortion.Methods:A multicenter, prospective randomized controlled trial was conducted across 18 hospitals from December 2021 to February 2023, involving 382 women who underwent artificial abortion. Participants were randomly allocated to receive either treatment with SCH gel (SCH group) or no treatment (control group) in a 1∶1 ratio. The primary outcome was endometrium thickness in 14 to 18 days after the first postoperative menstruation. Secondary outcomes included changes in menstrual volume during the first postoperative menstruation, menstruation resumption within 6 postoperative weeks, time to menstruation resumption, duration of the first postoperative menstruation, and incidence of dysmenorrhea.Results:Baseline characteristics of participants were comparable between the two groups (all P>0.05), with 95.3% (182/191) in SCH group and 92.7% (177/191) in the control group completed the study. The postoperative endometrial thickness in SCH group was significantly greater than that in the control group [(9.78±3.15) vs (8.95±2.32) mm; P=0.005]. SCH group also had significantly fewer participants with reduced menstrual volume [23 cases (12.6%, 23/182) vs 31 cases (17.5%, 31/177); P=0.038]. Although SCH group experienced less dysmenorrhea during the first postoperative menstrual period, this difference was not statistically significant [28.5% (51/179) vs 37.1% (65/175); P=0.083]. Outcomes were similar between SCH group and the control group regarding the proportion of participants who resumed menstruation within 6 weeks postoperatively, time to menstruation resumption, and duration of the first postoperative menstruation ( P=0.792, 0.485, and 0.254, respectively). No serious adverse events were observed during the study period, and no adverse events were attributed to SCH gel treatment. Conclusion:The application of SCH gel after artificial abortion is safe and might aid in the recovery of the endometrium.

Objective:To investigate the initial effectiveness of manual techniques versus navigation positioning system-assisted reconstruction for anterior cruciate ligament (ACL) injuries in children and adolescent populations.Methods:A retrospective analysis was conducted on 28 patients with ACL rupture who underwent primary total epiphyseal ACL reconstruction in the Sports Medicine Treatment Center of Honghui Hospital Affiliated to Xi'an Jiaotong University from January 2019 to October 2022. Patients were categorized into two groups based on the method of guide needle insertion: the manual group (guide needle insertion relying on the operator's expertise) and the robot-assisted group (guide needle insertion assisted by the Tianji robot navigation and positioning system). The manual group comprised 14 cases (9 males, 5 females) with an average age of 13.59±1.59 years, while the robot-assisted group included 14 patients (10 males, 4 females) with an average age of 13.27±1.66 years. The operation time, intraoperative fluoroscopy times, guide needle placement times, the distance between the central point of the internal articular opening of the tibial and femoral bone tunnel and the ideal point, the rate of epiphyseal inflammation, and the International Knee Documentation Committee (IKDC) subjective score, Lysholm score, KT-2000 ligament relaxation, lower limb force line were compared between the two groups.Results:The follow-up duration was 19.9±6.3 months for the manual group and 18.8±4.9 months for the robot group ( t=0.546, P=0.589). The manual group's operation duration was 123.0±12.6 min, significantly longer than the robot group's 96.4±12.9 min ( t=5.502, P<0.001). Intraoperative fluoroscopy was performed 11.8±3.1 times in the manual group, markedly more than the robot group's 3.7±0.8 times ( t=9.434, P<0.001). The robot group required only one guide needle placement for both femur and tibia, while the manual group had 5.7±1.2 placements on the femur side and 4.6±1.8 on the tibia side. The distance between the femoral joint's central point and the ideal point was 0.87±0.20 mm in the robot group, superior to the manual group's 1.92±0.64 mm ( t=5.816, P<0.001). Similarly, the distance between the central point and the ideal point was 1.15±0.34 mm for the robot group, better than the manual group's 1.94±0.55 mm ( t=4.582, P<0.001). No cases of epiphyseal irritation were observed in the robot group, while 21% (3/14) of the manual group experienced tibial or femoral epiphyseal plate involvement. At 3 months post-surgery, the robot group exhibited higher IKDC subjective scores (90.57±8.46) and Lysholm scores (86.29±5.09) compared to the manual group (83.50±6.19 and 80.93±5.93), respectively ( P<0.05). However, at the final follow-up, there were no significant differences in IKDC subjective scores, Lysholm scores, or KT-2000 ligament relaxation between the two groups ( P>0.05). Both groups showed normal lower limb force alignment and no abnormal growth or development. Conclusion:Tianji robot navigation and positioning system-assisted ACL reconstruction in children and adolescents offer advantages such as precise positioning, shorter operation times, reduced intraoperative fluoroscopy, faster recovery, and enhanced epiphyseal protection compared to manual methods.

Objective To investigate the effects of remazolam on melatonin secretion,sleep rhythm and postoperative delirium(POD)in elderly patients undergoing spinal surgery.Methods A total of 160 elderly patients,76 males and 84 females,aged 65-80 years,BMI 18.5-24.0 kg/m2,ASA physical status Ⅱ or Ⅲ,from November 2023 to January 2024 undergoing spinal surgery(lumbar interbody fusion,posterior approach)under general anesthesia were selected.The patients were divided into two groups by random number table method:the remazolam group(group R)and the propofol group(group P),80 pa-tients in each group.Group R was given remazolam 0.3 mg/kg for anesthesia induction,and then continued to pump remazolam 0.3-0.8 mg·kg-1·h-1 for anesthesia maintenance.Group P was given propofol 2.0 mg/kg for anesthesia induction,and then continued to pump propofol 4-6 mg·kg-1·h-1 for anesthesia maintenance.The levels of melatonin and cortisol were recorded at 04:00 a.m.on the day of surgery,1 day,2 and 3 days after surgery.Pittsburgh sleep quality index(PSQI)and VAS pain scores at rest were recorded 1 day before surgery,1 day and 2 days after surgery and before discharge.The occurrence of POD and post-operative sleep disorder(POSD)were recorded.The duration of extubation,PACU stay time,total analgesia pump compressions,effective analgesia pump compressions,number of remedial analgesia cases,intraoperative hypotension,postoperative nausea and vomiting,dizziness,respiratory depression and other adverse events were recorded.Results Compared with group P,the extubation time and PACU residence time in group R were significantly shortened(P＜0.05),the level of melatonin was significantly increased while the level of cortisol was significantly decreased at 4:00 a.m.,and the PSQI was significantly decreased 1 day after surgery(P＜0.05),the incidence of POD,POSD,and intraoperative hypotension were signifi-cantly decreased(P＜0.05).There were no significant differences in extubation time,total and effective times of analgesic pump,rate of remedial analgesia,intraoperative hypotension,postoperative nausea,vom-iting,dizziness and respiratory depression between the two groups.Conclusion Remazolam has little effect on the secretion rhythm of melatonin and cortisol and the sleep rhythm after spinal surgery in elderly pa-tients,and the recovery is faster,which can reduce the incidence of POD and alleviate the sleep disorder af-ter spinal surgery.

Objective·To investigate the effects of sennoside A(SA)on the formation of atherosclerotic plaque and the expression of 5-hydroxytryptamine(5-HT)and its receptor in mice with diabetes mellitus type 2(T2DM).Methods·Twelve mice with knocked-out apolipoprotein E gene were randomly divided into two groups,namely the model group and the model+SA group,with six mice in each group.Six C57BL/6J mice with the same genetic background were used as the control group.The control group was fed with normal diet,and the model group and the model+SA group were given intraperitoneal injection of streptozotocin(30 mg/kg)daily on the basis of high-fat diet to establish a model of T2DM.The model+SA group was given SA daily by gavage for 8 weeks,and the control group and the model group were given equal volume of distillation-distillation H2O by gavage.The body weight,fasting blood glucose(FBG)and 2-h postprandial blood glucose of mice were compared before and after modeling and treatment.The area of aortic plaque was observed by oil red O staining and hematoxylin-eosin(H-E)staining,and the level of 5-HT in serum and thoracic aorta was measured by ELISA kit.Western blotting was used to detect the expression of 5-hydroxytryptamine receptor 2B(HTR2B)and serotonin transporter(SERT)in thoracic aorta of mice.Results·Compared with the control group,the body weight,FBG and 2-h postprandial blood glucose in the model group increased,and glucose metabolism was disordered.The expression of HTR2B and SERT protein in thoracic aorta increased,while the concentration of 5-HT in thoracic aorta decreased.The serum 5-HT concentration increased(all P<0.05).After treatment with SA,compared with the model group,the body weight of the model+SA group decreased,and FBG and 2-h postprandial blood glucose were significantly improved.The area of aortic plaque and the expression of HTR2B and SERT protein in thoracic aorta significantly decreased,while the concentration of 5-HT increased.The serum 5-HT concentration decreased(all P<0.05).Conclusion·SA can reduce atherosclerotic plaque area in T2DM mice,which may be related to lowering blood glucose and inhibiting the expression of 5-HT and its receptor.
