The new era imposes heightened demands on medical professionals,who must not only possess a solid theoretical foundation but also exhibit strong practical skills and innovative capabilities.The quality of medical func-tional laboratory construction is crucial for cultivating high-caliber medical talents.In light of the current developmental status and trends regarding functional experiment teaching within Chinese higher education institutions,particularly the disparities in development across various regions and institutions,the Functional Experiment Teaching Committee of the Chinese Pathophysiology Society has developed an expert consensus on laboratory construction standards.This consensus was established through comprehensive investigations,research,and extensive discussions to provide a reference for di-verse institutions to continuously enhance their levels of laboratory construction.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective:To investigate the efficacy and safety of transurethral incision for the treatment of ureterocele in infants.Methods:A retrospective analysis of 28 cases of ureterocele admitted from March 2012 to May 2023 were reviewed, all of which were less than 1 year old, 16 male and 12 female, with an average age of(5.7±3.5)months. The ureterocele was located on the left side in 8 cases, on the right side in 15 cases, and bilaterally in 5 cases. There were 12 cases of single system ureterocele, of which 7 cases were unilateral and 5 cases were bilateral. Duplex system ureterocele was observed in 16 cases, all of which were unilateral. Clinical manifestations: urinary tract infection in 13 cases, 11 cases of ureterocele or hydronephrosis and ureteral dilation were found during antenatal examination, and 4 cases of ureterocele were found after birth. Urological ultrasound, intravenous pyelography(IVP) and voiding cystourethrography(VCUG) were performed in all children, and 17 cases underwent magnetic resonance urolography (MRU), and confirm the diagnosis of ureterocele preoperatively. All of the cases were performed the transurethral incision.The ureterocele was punctured and incised 1-2 mm at the base of the bulge, and 2-4 points were punctured according to the bulge atrophy. Bilateral ureteroceles were punctured and incised simultaneously. Postoperative urine routine test, urinary tract color ultrasound and VCUG were performed to determine if there is urinary tract infection, hydronephrosis, ureteral dilation and bulging, and whether a second surgery is needed.Results:All operations were conducted successfully. The intraoperative bleeding was less than 3 ml and no intraoperative complications. The operative time was (28.4±10.3) min. The median postoperative follow-up was 34 (32, 36) months. Six cases underwent postoperative VCUG examination. Eleven children were recovered well with single systemic ureterocele. One child developed grade Ⅳ vesicoureteral reflux(VUR)and combined with bladder diverticulum, and ureterocele underwent open diverticulotomy and ureteral reimplantation six months after surgery. Nine children were recovered well with duplex systemic ureterocele. Six cases of children developed infection, of which 2 cases had an infection once within one month after TUI, and the other four cases still had intermittent infections after six months and VCUG was performed, and one case showed grade Ⅲ VUR of the lower ureter, which was observed conservatively, while the other three cases had enlarged cysts but no VUR, and upper heminephrectomy was performed, and the patients recovered well after surgery. Except for these 6 exceptions, in another case, after ten years of follow-up, the ureterocele became larger but no VUR, and the results were good after a second transurethral incision. There was no significant difference in the postoperative infections, new VUR cases, and secondary surgeries between the two groups.Conclusions:Transurethral incision has good surgical effect on children with single system ureterocele and duplex system ureterocele, and has advantages of easy operation, less trauma, safety and effectiveness, and few complications. It deserves to be recommended as the treatment of choice, especially for infants and young children.

Objective To investigate the expression of lncRNA SNHG8 in placenta accrete(PA)and its effect on trophoblast invasion and migration.Methods qRT-PCR was used to detect the expression of lncRNA SNHG8 in placenta tissue of 30 cases in PA group and 30 cases in control group,and the correlation between lncRNA SNHG8 expression and prenatal ultrasound score of 30 cases in PA group was analyzed.Transwell and scratch assay were used to detect the effect of lncRNA SNHG8 interference on the invasion and migration of human chorionic trophoblast cells(HTR8/SVneo cells),and western blot was used to detect the expression of MMP-2 and MMP-9.The downstream targets of lncRNA SNHG8 were predicted by StarBase software,and the expression of lncRNA SNHG8 was detected in placental tissues of the two groups.Dual luciferase reporter assay was used to detect the targeting relationship between lncRNA SNHG8 and miR-542-3p.Results Compared with that of the control group,the expression of lncRNA SNHG8 was up-regulated in the placenta tissue of the PA group(P<0.05),and it was positively correlated with prenatal ultrasound score.Interference with lncRNA SNHG8 inhibited the invasion and migration of trophoblast cells(P<0.05);the protein expression of MMP-9 and MMP-2 also decreased signifi-cantly(P<0.05).Biological prediction indicates that miR-542-3p had a binding site with lncRNA SNHG8,and miR-542-3p expression was down-regulated in PA placental tissue(P<0.05).Dual luciferase reporter assay confirmed that lncRNA SNHG8 could target miR-542-3p.Compared with si-SNHG8+inhibitor-NC,co-transfection of si-SNHG8 and miR-542-3p inhibitor enhanced the invasion and migration ability of trophoblast cells(P<0.05).Conclusion lncRNA SNHG8 is highly expressed in PA and is related to the severity of PA.LncRNA SNHG8 promotes the invasion and migration of trophoblast by regulating the level of miR-542-3p.The study suggests that lncRNA SNHG8 plays an important role in the invasion and migration of PA trophoblast cells,which is expected to be a clinical diagnostic biomarker and therapeutic target.

Objective To assess effect of ultrasound-guided erector spinae plane block(ESPB)combined with patient controlled intravenous analgesia(PCIA)on postoperative analgesia after cesarean section.Methods A total of 120 full-term singleton pregnant women who underwent cesarean section under spinal anesthesia at Jiaxing Maternal and Child Health Care Hospital from May 2022 to August 2023 were selected.Participants were randomly divided into three groups using a random number table:Group E(ESPB combined with PCIA),group T[transversus abdominis plane(TAP)block combined with PCIA],and control group(PCIA alone),with 40 women in each group.Visual analogue scale(VAS)and Bruggrmann comfort scale(BCS)scores during rest and coughing were recorded at 4h,8h,12h,24h,and 48h postoperatively.Number of effective PCIA presses,total sufentanil dosage,proportion of rescue analgesia and maternal satisfaction were also documented within 48h.Additionally,adverse reactions and neonatal outcomes were observed within the same 48h period.Results Postoperatively,VAS scores for rest and coughing in group E at 8h,12h,24h were significantly lower than those in group T,those in two groups were lower than those in control group(P＜0.05).Postoperatively at 8h,12h,and 24h,BCS scores in group E were significantly higher than those in group T,with both higher than those in control group(P＜0.05).Within 48h after surgery,the number of effective PCIA presses,proportion of rescue analgesia and total sufentanil dosage in group E were lower than those in group T,both lower than those in control(P＜0.05).Moreover,maternal satisfaction score in group E was significantly higher than that in group T,that in two groups was significantly higher than that in control group(P＜0.05).Within 48h after surgery,there were no significant differences in adverse reactions or neonatal outcomes among the three groups(P＞0.05).Conclusion Ultrasound-guided ESPB combined with PCIA outperforms TAP block combined with PCIA,with reducing analgesic dose and enhancing maternal satisfaction and comfort.

Objective: To explore the improvement effect of hypnotherapy on dysmenorrhea symptoms of female college students with primary dysmenorrhea, in order to provide reference for the intervention and treatment of female college students with primary dysmenorrhea. Methods: From Septerber to December 2021, 90 female college students diagnosed with primary dysmenorrhea in Qinzhou First People s Hospital were randomly divided into hypnotic suggestion group( n =30), hypnotic relaxation group ( n =30) and control group( n =30). The 10 session hypnotic suggestion and 10 session hypnotic relaxation interventions were carried out while the control group received no intervention. Participants in the three groups were assessed by using the Visual Analogue Scale(VAS), Beck Depression Inventory Ⅱ(BDI Ⅱ), State Anxiety Inventory(SAI), Questionnaire of Quality of Life of College Students(QOLCS), Cox Dysmenorrhea Symptom Scale (CMSS) before and after intervention. Results: After intervention, the VAS, BDI Ⅱ and SAI scores of the hypnotic suggestion group and the hypnotic relaxation group significantly decreased compared to those before the intervention( t =7.04, 13.32, 3.58, 2.15, 2.52, 2.01, P <0.05). There were statistically significant differences in VAS, BDI Ⅱ and SAI scores among the three groups( F =24.71, 29.57, 6.60, P <0.01). After intervention, the QOLCS total score, physical, psychological and behavioral dimension scores in the hypnotic suggestion group and the hypnotic relaxation group significantly improved( t =-4.61, -3.36, -3.12, -2.81, -2.71, -2.19, -2.69, -2.28, P <0.05). There were statistically significant differences in QOLCS total score, physical, psychological, behavioral, environmental, and social support dimension scores among the three groups( F =10.36, 4.14, 5.14，4.81, 7.07, 5.53, P <0.05). After the intervention, the CMSS dysmenorrhea severity and dysmenorrhea duration scores in the hypnotic suggestion group and the hypnotic relaxation group were significantly lower than those before the intervention( t =5.66, 4.70, 3.09, 2.21, P <0.05). There were significant differences in CMSS dysmenorrhea severity and dysmenorrhea duration scores among the three groups( F=15.33, 12.33, P <0.05). Conclusion Hypnotherapy can help relieve pain of female college students with primary dysmenorrhea，improve depression and anxiety.

Objective:To investigate the analgesic efficacy of dexmedetomidine combined with dizosine after lumbar internal fixation and its effects on hyperalgesia.Methods:Seventy-two patients who underwent lumbar internal fixation in General Hospital of Armed Police and Marine Police between April 2018 and June 2019 were included in this study. They were randomly assigned to undergo either flurbiprofen axetil and dizosine administration (control group) or dexmedetomidine and dizosine (observation group) for postoperative analgesia. Mechanical pain, degree of postoperative pain, and incidence of complications were recorded in each group.Results:At 6, 24 and 48 hours after surgery, peri-wound pain threshold in the observation group was (119.52 ± 20.42) points, (120.19 ± 17.44) points, (120.94 ± 20.73) points, respectively, which were significantly higher than (108.42 ± 15.24) points, (107.63 ± 16.83) points, (108.47 ± 17.82) points in the control group ( t = 0.01, 0.00, 0.01, all P < 0.05). At 24 and 48 hours after surgery, forearm pain threshold in the observation group was (109.93 ± 15.87) points and (110.79 ± 22.85) points, respectively, which were significantly higher than (97.07 ± 16.49) points and (95.63 ± 24.06) points ( t = 3.37, 2.74, both P < 0.05). There was no significant difference in Ramsay Sedation Scale score between the two groups ( P > 0.05). There was no significant difference in the dose of dizosine used within 48 hours after surgery between the two groups ( P > 0.05). The incidence of postoperative complications in the observation group was significantly lower than that in the control group [8.33% (3/36) vs. 27.78% (10/36), χ2 = 4.60, P < 0.05]. Conclusion:Dexmedetomidine combined with dizosine exhibits obvious analgesic efficacy after lumbar internal fixation. The combined therapy can effectively prevent hyperalgesia with a low incidence of comphications.
