Flexible ureteral lithotripsy (FURL) under general anesthesia (GA) is the dominant method in the treatment of renal and upper ureteral calculi，but some patients cannot tolerate GA.In recent years，there has been a growing interest in the use of local anesthesia (LA) as a safe and effective alternative.And it is also an option for patients who have calculi ≤20 mm with high fragility，lower CT value and better compatibility.Before surgery，it is important to conduct relevant examinations，evaluate the status of patients，prevent infections，and indwell ureteral stents.During surgery，lithotomy position，scissors position，prone leg position and other positions should be selected according to the specific conditions of patients.LA drugs should be used to control physiological pain and relieve psychological anxiety.Patients' breathing state should be carefully monitored，and appropriate ureteroscope and lens sheath should be selected for the success and safety of the operation.In this paper，the perioperative management of FURL under LA is briefly summarized，so as to provide reference for clinical practice.

OBJECTIVE: To explore the feasibility and effectiveness of suture anchor double-pulley technique combined with suture three-dimensional binding via bone tunnel technique for avulsion fractures of the inferior pole of the patella. METHODS: A clinical data of 38 patients with avulsion fractures of the inferior pole of the patella, who met the selective criteria and were admitted between September 2021 and April 2023, was retrospectively analyzed. The fractures were treated with suture anchor double-pulley technique combined with suture three-dimensional binding via bone tunnel technique in 18 cases (group A) and steel wire tension-band fixation in 20 cases (group B). There was no significant difference in terms of age, gender, cause of fracture, side of fracture, and disease duration between the two groups ( P>0.05). The length of incision, operation time, occurrence of complications, the range of motion of knee joint, and Böstman score of knee joint at last follow-up were recorded. The fracture healing was evaluated through X-ray films and the time of fracture healing was recorded. RESULTS: All incisions healed by first intention. The length of incision was significantly shorter in group A than in group B ( P<0.05). There was no significant difference in the operation time between the two groups ( P>0.05). All patients were followed up 12-24 months (mean, 16.1 months). X-ray films showed that all fractures healed and there was no significant difference in the healing time between the two groups ( P>0.05). At last follow-up, the range of motion and Böstman score of the knee joint in group A were significantly better than those in group B ( P<0.05). During follow-up, 1 patient (5.6%) in group A had one anchor mild prolapse and 3 patients (15.0%) occured internal fixation irritation in group B. But there was no significant difference in the incidence of complications between the two groups ( P>0.05). CONCLUSION For the avulsion fractures of the inferior pole of the patella, the suture anchor double-pulley technique combined with suture three-dimensional binding via bone tunnel technique has advantages of reliable fixation, small incision, avoidance of secondary operation to remove internal fixator, and fewer complications, with definite effectiveness.

OBJECTIVE: To compare the effectiveness of using a composite loop plate to reconstruct the coracoclavicular ligament around the coracoid process and using a clavicular hook plate for fixation in treatment of Rockwood type Ⅲ acute acromioclavicular joint dislocation. METHODS: A retrospective analysis was conducted on the clinical data of 60 patients with Rockwood type Ⅲ acute acromioclavicular joint dislocation who were admitted between June 2022 and September 2023 and met the selection criteria. Among them, 30 patients were treated with the composite loop plate to reconstruct the coracoclavicular ligament around the coracoid process (loop plate group) and 30 with clavicular hook plate fixation (hook plate group). There was no significant difference in baseline data between the two groups ( P>0.05), including gender, age, injured side, cause of injury, disease duration, preoperative visual analogue scale (VAS) score for pain, and Constant-Murley score. The incision length, operation time, length of hospital stay, and the occurrence of complications during follow-up were recorded. The Constant-Murley score and VAS score were used to evaluate shoulder joint function and pain, and the differences (change values) of the indicators between before operation and at 6 months after operation were calculated for inter-group comparison. In the loop plate group, the coracoclavicular distance (CCD) on the anteroposterior X-ray films of the acromioclavicular joint was measured at 1 day and 6 months after operation to assess the loss of acromioclavicular joint reduction. RESULTS: The incision length of the loop plate group was significantly shorter than that of the hook plate group ( P<0.05). There was no significant difference in the operation time and the length of hospital stay between the two groups ( P>0.05). All incisions healed by first intention after operation. All patients were followed up 12-18 months (mean, 16.3 months). There was no significant difference in the follow-up time between groups ( P>0.05). The Constant-Murley scores and VAS scores of both groups significantly improved at 6 months after operation when compared with those before operation ( P<0.05); the differences in the change values of the two indicators between groups were significant ( P<0.05). The CCD of the loop plate group were (10.40±0.83) mm at 1 day and (10.70±0.68) mm at 6 months and no repositioning loss was observed. Three cases in the hook plate group had residual shoulder joint pain after operation. The difference in the accidence of complications between groups was not significant ( P>0.05). CONCLUSION For Rockwood type Ⅲ acute acromioclavicular joint dislocation, compared with the clavicular hook plate fixation, the composite loop plate for reconstructing the coracoclavicular ligament around the coracoid process has the advantages of simple operation, safety, minimally invasive, good functional recovery, and fewer complications. Moreover, it avoids the need for a second surgery to remove the internal fixation device, and the patient acceptance and satisfaction are higher.

Objective To explore the clinical efficacy and safety of immediate laparoscopic radical prostatectomy immediately following the diagnosis of locally advanced prostate cancer.Methods A retrospective analysis was performed for 63 patients with locally advanced prostate cancer who met the inclusion criteria diagnosed in The 1st People's Hospital of Qujing City,Yunnan Province from January 2018 to January 2023.All patients were diagnosed via ultrasound-guided transperineal prostate biopsy.The experimental group consisted of 37 patients who underwent immediate laparoscopic radical prostatectomy after pathological diagnosis,followed by postoperative adjuvant hormone therapy.The control group included 26 patients who first received 3 months of neoadjuvant hormone therapy before undergoing radical surgery,followed by adjuvant hormone therapy postoperatively.The two groups were compared in terms of surgical duration,intraoperative blood loss,length of hospital stay,duration of catheterization,positive surgical margin rate,rectal injury,positive lymph node rate,incidence of urinary fistula and lymphatic leakage,changes in PSA level,postoperative urinary control,biochemical recurrence and distant metastasis.Results In the control group,serum PSA levels,prostate volume,and clinical staging significantly decreased after neoadjuvant hormon therapy.The positive surgical margin rate in the experimental group was significantly higher than that in the control group,with a statistically significant difference(P<0.05).There were no statistically significant differences between the two groups in terms of surgical duration,intraoperative blood loss,length of hospital stay,duration of catheterization,rectal injury,positive lymph node rate,incidence of urinary fistula and lymphatic leakage(P>0.05).Follow-up at 18 to 36 months revealed no statistically significant differences between the two groups in terms of serum PSA levels at one month post-surgery,complete urinary control rate at six months post-surgery,and biochemical recurrence and distant metastasis at one and two years post-surgery(P>0.05).Conclusion Immediate laparoscopic radical prostatectomy following the diagnosis of locally advanced prostate cancer is a clinically safe and feasible treatment option.Noadjuvant hormone therapy reduces tumor staging,lowers the positive surgical margin rate,significantly decreases prostate volume,and provides greater operational space without increasing surgical risks.

Objective To evaluate the efficacy of complete pelvic floor peritoneal reconstruction in reducing postoperative ileus incidence and accelerating recovery following laparoscopic radical cystectomy with orthotopic neobladder construction.Methods A retrospective study was conducted to select 62 patients who underwent the operation in Qujing Hospital Affiliated to Kunming Medical University from January 2017 to September 2024.According to whether complete pelvic floor peritoneal reconstruction was performed during the operation,they were divided into the conventional group(n=25)and the reconstruction group(n=37).Postoperative ileus rates and recovery parameters were compared to assess the clinical value of complete pelvic floor peritoneal reconstruction.Results The reconstruction group showed better postoperative recovery compared to the routine group:gastrointestinal function recovery time[3(2,4)d vs 4(3,5)d,P=0.032],abdominal drainage time[12(10,13.5)d vs 14(12,15)d,P=0.006],pelvic drainage time[12(9,13.5)d vs 14(11,16)d,P=0.015],postoperative hospital stay[18(15.5,26)d vs 25(17,30.5)d,P=0.016],and hospital expenses[(53,695.67±10,182.43)yuan vs(60,803.73±14,449.24)yuan,P=0.027].Postoperative nutritional markers,including total protein[(64.49±6.82)g/L vs.(61.56±4.03)g/L,P=0.038]and albumin[(36.08±5.29)g/L vs.(33.40±3.57)g/L,P=0.020],were higher in the reconstruction group.No significant difference was found in ileus incidence(44.00%vs.32.43%,P=0.355).Other parameters—baseline characteristics,postoperative globulin and prealbumin levels,gastric tube retention,stent/catheter removal time,and complications(anastomotic leakage,urinary fistula,wound infection)—showed no intergroup differences(P>0.05).Conclusion The application of complete pelvic floor peritoneal reconstruction technique in laparoscopic radical cystectomy with orthotonic neobladder provides better protection for the intestine,reduces surgical area adhesions,promotes gastrointestinal function recovery,shortens abdominal and pelvic drainage times,accelerates patient rehabilitation,reduces hospital stay and expenses.However,whether it can effectively reduce postoperative intestinal obstruction rates still requires more data and experimental verification.

Objective To analyze the risk factors influencing the occurrence of atherosclerosis in patients with type 2 diabetes, and to construct and evaluate a nomogram prediction model. Methods Multivariate logistic regression was used to analyze the risk factors of atherosclerosis in type 2 diabetes mellitus, and R software was used to build a nomogram prediction model. The accuracy and clinical validity of the model were verified by using H-L fit curve, area under ROC curve and calibration curve. Results The prevalence rate of atherosclerosis was 56.37%. Independent risk factors for atherosclerosis in type 2 diabetes mellitus (P<0.05) were body weight (OR=1.42，P<0.05), glycated serum protein (OR=1.35, P<0.05), lactate dehydrogenase (OR=1.17, P<0.05), alkaline phosphatase (OR=0.79, P<0.05), hyperlipidemia (OR=2.30, P<0.05), stroke (OR=4.20, P<0.05), coronary heart disease (OR=64.54, P<0.05), lower extremity artery disease (OR=24.52, P<0.05), and other endocrine diseases (OR=1.65 , P<0.05). The area under ROC curve was 0.91, the slope of the calibration curve was close to 1, and the H-L fit curve χ²=3.11. The internal verification result of the constructed nomogram prediction model was P=0.93. External verification of patients in the test set showed that the area under ROC curve was 0.91, indicating good differentiation and accuracy of the model. Conclusion The prediction model established by using the risk factors screened in this study has a high accuracy and differentiation, and medical staff can take effective prevention measures according to the individual factors of patients.

Objective To explore the protective mechanism of Zuogui Jiangtang Jieyu Formula(ZGF)on synaptic damage of hippocampal neurons based on leukocyte mono-immunoglobulin-like receptor 3(CD300f)/glucose transporter 1(GLUT1)signal-mediated microglial glucose metabolism in rats with diabetes-related depression.Methods Eighty male SD rats were randomly selected using random number table method,with 10 rats serving as the normal group.The remaining 70 rats were fed a high-fat diet for 4 weeks and then injected once with 38 mg/kg of streptozotocin via the tail vein to replicate the diabetes rat model.Sixty rats were screened and successfully modeled,which were randomly divided into the model,CD300f blocker,CD300f agonist,metformin+fluoxetine(metformin 0.18 g/kg+fluoxetine 1.8 mg/kg),and ZGF high-and low-dose(20.52 and 10.26 g/kg,respectively)groups using random number table method.In addition to the normal group,the rats in the other groups underwent chronic unpredictable mild stress combined with isolation feeding for 28 days to replicate the diabetes-related depression rat model.The metformin+fluoxetine and ZGF high-and low-dose groups were subjected to continuous intragastrial administration for 14 days after the second week of modeling.The normal and model groups were administered an equal amount of distilled water by gavage.The CD300f blocker group and agonist group received microinjection into the hippocampus,with injection of myeloid cell trigger receptor inhibitory factor(CLM1,2 μg/kg)and immunoglobulin Fc surface protein(Fcγ,5 μg/kg)once a week,respectively.Depression-like behavior in rats was evaluated using open-field and forced swimming tests after the intervention.Biochemical analysis was used to detect the glucose,lactic acid,and adenosine diphosphate(ADP)/adenosine triphosphate(ATP)ratio contents.The insulin,5-hydroxytryptamine(5-HT),and dopamine(DA)levels in the hippocampus were detected using an enzyme-linked immunosorbent assay.Immunofluorescence was used to detect the average fluorescence intensity of CD300f,GLUT1,regulating synaptic membrane wxocytosis 3(RIMS3),and synapse-associated protein 102(SAP102)in hippocampal tissue.Western blotting was used to detect the CD300f,GLUT1,RIMS3,and SAP102 protein expression levels in the hippocampus.The synaptic damage of hippocampal neurons was observed using Nissl staining and transmission electron microscope.Results Compared with the normal group,the model group showed a decrease in the total active distance in the open-field test and an increase in forced swimming immobility time,with an increase in glucose and lactic acid contents and ADP/ATP ratio,whereas a decrease in insulin,5-HT,and DA levels was observed in the hippocampus.The average fluorescence intensity and relative protein expression levels of CD300f,GLUT1,RIMS3,and SAP102 in hippocampal tissue decreased(P<0.05),and the synaptic ultrastructure of hippocampal neurons was damaged.Compared with the model group,depression-like behavioral changes,glucose metabolism,and monoamine neurotransmitter imbalance were alleviated in the CD300f agonist group and ZGF high-and low-dose group(P<0.05).The average fluorescence intensity and relative protein expression levels of CD300f,GLUT1,RIMS3,and SAP102 in the hippocampus of the CD300f agonist group and the ZGF high-dose group were all increased(P<0.05),and synaptic damage was alleviated.The abnormal levels of glucose,lactate,ADP/ATP,5-HT,and CD300f protein expression were aggravated in the CD300f blocker group(P<0.05),and synaptic damage was aggravated.Conclusion ZGF can alleviate glucose metabolism disorders in hippocampal microglia and synaptic damage in hippocampal neurons in rats with diabetes-related depression.Its mechanism may be related to regulating the CD300f/GLUT1 signaling pathway.

Objective:To investigate the prognosis of patients with initially resectable gastric cancer liver metastasis (GCLM) who were treated by different modalities, and analyze the influencing factors for prognosis of patients.Methods:The retrospective cohort study was conducted. The clinicopathological data of 327 patients with initially resectable GCLM who were included in the database of a nationwide multicenter retrospective cohort study on GCLM based on real-world data from January 2010 to December 2019 were collected. There were 267 males and 60 females, aged 61(54,68)years. According to the specific situations of patients, treatment modalities included radical surgery combined with systemic treatment, palliative surgery combined with systemic treatment, and systemic treatment alone. Observation indicators: (1) clinical characteristics of patients who were treated by different modalities; (2) prognostic outcomes of patients who were treated by different modalities; (3) analysis of influencing factors for prognosis of patients with initially resectable GCLM; (4) screening of potential beneficiaries in patients who were treated by radical surgery plus systemic treatment and patients who were treated by palliative surgery plus systemic treatment. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the independent sample t test. Measurement data with skewed distribution were represented as M( Q1, Q3), and comparison between groups was conducted using the rank sum test. Count data were described as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test. The Kaplan-Meier method was used to calculate survival rate and draw survival curve, and Log-Rank test was used for survival analysis. Univariate and multivariate analyses were conducted using the COX proportional hazard regression model. The propensity score matching was employed by the 1:1 nearest neighbor matching method with a caliper value of 0.1. The forest plots were utilized to evaluate potential benefits of diverse surgical combined with systemic treatments within the population. Results:(1) Clinical characteristics of patients who were treated by different modalities. Of 327 patients, there were 118 cases undergoing radical surgery plus systemic treatment, 164 cases undergoing palliative surgery plus systemic treatment, and 45 cases undergoing systemic treatment alone. There were significant differences in smoking, drinking, site of primary gastric tumor, diameter of primary gastric tumor, site of liver metastasis, and metastatic interval among the three groups of patients ( P<0.05). (2) Prognostic outcomes of patients who were treated by different modalities. The median overall survival time of the 327 pati-ents was 19.9 months (95% confidence interval as 14.9-24.9 months), with 1-, 3-year overall survival rate of 61.3%, 32.7%, respectively. The 1-year overall survival rates of patients undergoing radical surgery plus systemic treatment, palliative surgery plus systemic treatment and systemic treatment alone were 68.3%, 63.1%, 30.6%, and the 3-year overall survival rates were 41.1%, 29.9%, 11.9%, showing a significant difference in overall survival rate among the three groups of patients ( χ2=19.46, P<0.05). Results of further analysis showed that there was a significant difference in overall survival rate between patients undergoing radical surgery plus systemic treatment and patients undergoing systemic treatment alone ( hazard ratio=0.40, 95% confidence interval as 0.26-0.61, P<0.05), between patients undergoing palliative surgery plus systemic treatment and patients under-going systemic treatment alone ( hazard ratio=0.47, 95% confidence interval as 0.32-0.71, P<0.05). (3) Analysis of influencing factors for prognosis of patients with initially resectable GCLM. Results of multivariate analysis showed that the larger primary gastric tumor, poorly differentiated tumor, larger liver metastasis, multiple hepatic metastases were independent risk factors for prognosis of patients with initially resectable GCLM ( hazard ratio=1.20, 1.70, 1.20, 2.06, 95% confidence interval as 1.14-1.27, 1.25-2.31, 1.04-1.42, 1.45-2.92, P<0.05) and immunotherapy or targeted therapy, the treatment modality of radical or palliative surgery plus systemic therapy were independent protective factors for prognosis of patients with initially resectable GCLM ( hazard ratio=0.60, 0.39, 0.46, 95% confidence interval as 0.42-0.87, 0.25-0.60, 0.30-0.70, P<0.05). (4) Screening of potentinal beneficiaries in patients who were treated by radical surgery plus systemic treatment and patients who were treated by palliative surgery plus systemic treatment. Results of forest plots analysis showed that for patients with high-moderate differentiated GCLM and patients with liver metastasis located in the left liver, the overall survival rate of patients undergoing radical surgery plus systemic treatment was better than patients undergoing palliative surgery plus systemic treatment ( hazard ratio=0.21, 0.42, 95% confidence interval as 0.09-0.48, 0.23-0.78, P<0.05). Conclusions:Compared to systemic therapy alone, both radical and palliative surgery plus systemic therapy can improve the pro-gnosis of patients with initially resectable GCLM. The larger primary gastric tumor, poorly differen-tiated tumor, larger liver metastasis, multiple hepatic metastases are independent risk factors for prognosis of patients with initial resectable GCLM and immunotherapy or targeted therapy, the treatment modality of radical or palliative surgery plus systemic therapy are independent protective factors for prognosis of patients with initially resectable GCLM.
