Objective: To explore the mechanism of cistanche deserticola(meat cistanche) in treating Alzheimer′s disease(AD) through network pharmacology, molecular docking, and animal experiments. Methods : Effective components of meat cistanche were mined from the TCMSP database, and AD-related targets were filtered using the SwissTargetPrediction, DisGeNET, and GeneCards databases. The intersection of these targets was analyzed using protein-protein interaction(PPI) networks. Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment analyses were conducted via the Metascape database. Molecular docking of meat cistanche′s active components with core targets was performed using AutoDock Vina. Based on network pharmacology predictions, an AD model was established using 8-month-old SAMP8 mice, with Morris water maze tests assessing learning and cognitive functions, Nissl staining observing hippocampal neuron morphology, and enzyme-linked immunosorbent assays and Western blotting detecting the expression levels of cAMP signaling pathway-related proteins in hippocampal tissues. Results : Network pharmacology analysis predicted that meat cistanche might act on 74 AD targets through 8 active components. Molecular docking showed high affinity of active components like acteoside with core targets such as ESR1, BDNF, MAPK1, and APP. KEGG analysis indicated involvement in pathways related to cancer, cAMP signaling, and AD. Animal experiments demonstrated that meat cistanche effectively improved learning and cognitive impairments in AD mice and alleviated hippocampal neuron damage. ELISA and Western blotting results indicated that meat cistanche significantly increased the expression levels of cAMP, PKA, P-CREB in the cAMP pathway and promoted the expression of downstream neurotrophic factor BDNF. Conclusion Meat cistanche can improve learning and cognitive disorders in AD model mice and may exert therapeutic effects on AD by up-regulating the cAMP signaling pathway and the expression of downstream BDNF protein targets, thereby improving hippocampal neuron injury.

Objective To analyze the risk factors for chronic cough following pulmonary surgery in patients with non-small cell lung cancer (NSCLC). Methods A retrospective analysis was conducted on 427 NSCLC patients who underwent pulmonary surgery in the Department of Thoracic Surgery, The First Affiliated Hospital of the University of Science and Technology of China, between January 2021 and June 2023. Patients were categorized into a chronic cough group (103 patients) and a non-chronic cough group (324 patients) based on the presence of cough at 8 weeks post-surgery. A comparative analysis was performed between the two groups, considering gender, age, smoking history, comorbidities, preoperative pulmonary function indicators, pleural adhesion, anesthesia duration, surgical site, operative techniques, lymph node dissection methods, tumor maximum diameter, and postoperative chest tube duration. Factors showing statistical significance in univariate analysis underwent multivariate logistic regression analysis. Results Among the 427 patients undergoing pulmonary surgery, there were 165 males and 262 females, with an average age of (59.93±12.11) years. The incidence of chronic cough was 24.12%. Univariate analysis revealed significant differences in smoking history, preoperative pulmonary function indicators, pleural adhesion, anesthesia duration ≥135.5 minutes, surgical site, operative techniques, lymph node dissection methods, tumor maximum diameter, and postoperative chest tube duration (P<0.05). Multivariate logistic regression analysis indicated that the surgical site (right upper lung), operative techniques (lobectomy), lymph node dissection, and anesthesia time ≥135.5 minutes were independent risk factors for chronic cough following pulmonary surgery. Conclusion Patients undergoing right upper lung surgery, lobectomy, lymph node dissection, and experiencing anesthesia duration ≥135.5 minutes are at a higher risk of developing chronic cough post-pulmonary surgery.

Temporomandibular joint (TMJ) diseases are common clinical conditions. The number of patients with TMJ diseases is large, and the etiology, epidemiology, disease spectrum, and treatment of the disease remain controversial and unknown. To understand and master the current situation of the occurrence, development and prevention of TMJ diseases, as well as to identify the patterns in etiology, incidence, drug sensitivity, and prognosis is crucial for alleviating patients′suffering.This will facilitate in-depth medical research, effective disease prevention measures, and the formulation of corresponding health policies. Cohort construction and research has an irreplaceable role in precise disease prevention and significant improvement in diagnosis and treatment levels. Large-scale cohort studies are needed to explore the relationship between potential risk factors and outcomes of TMJ diseases, and to observe disease prognoses through long-term follw-ups. The consensus aims to establish a standard conceptual frame work for a cohort study on patients with TMJ disease while providing ideas for cohort data standards to this condition. TMJ disease cohort data consists of both common data standards applicable to all specific disease cohorts as well as disease-specific data standards. Common data were available for each specific disease cohort. By integrating different cohort research resources, standard problems or study variables can be unified. Long-term follow-up can be performed using consistent definitions and criteria across different projects for better core data collection. It is hoped that this consensus will be facilitate the development cohort studies of TMJ diseases.

Objective:To investigate the effect of perineal single-port robot-assisted radical prostatectomy.Methods:A retrospective analysis was conducted on clinical data from 60 patients who underwent perineal single-port robot-assisted laparoscopic radical prostatectomy at our hospital between July 2019 and July 2022. The mean age of the patients was (65.9±7.6) years and the mean BMI was (24.1±2.9) kg/m 2. The median (IQR) prostate volume was 32.7 (23.8, 41.2) ml, and the median (IQR) preoperative PSA value was 8.8 (6.8, 12.6) ng/ml. Preoperative pathology revealed a Gleason score of 6 in 21 patients, Gleason score of 7 in 35 patients and Gleason score of 8 in 4 patients. There were 12 patients clinically staged as T 1 and 48 patients as T 2. A total of 18 patients underwent a total of 23 previous abdominopelvic surgeries. The patient is placed in an exaggerated lithotomy position with the head down and feet elevated approximately 15°. A 3-5 cm incision was made approximately 2 cm above on the mid-perineum between the bilateral ischial tuberosities. Next, the rectourethral muscle was divided, and the space anterior to the rectum was developed by blunt dissection. The levator ani muscles were separated to expose Denonvilliers’ fascia. Then, the disposable multi-channel laparoscopic surgical access system is inserted with a surgical wound protector. Denonvilliers’ fascia was incised transversely and the ampulla of the vas deferens, which were subsequently divided. Blunt separation is performed on both sides along the capsule of the prostate, and then, the vascular pedicles of the prostate are ligated. The membranous urethra was severed after complete urethral separation at the tip of the prostate at the urethral junction. The bladder neck was freed and dissected. The prostate and seminal vesicles were removed and a vesicourethral anastomosis is performed. A perineal drain were left in place. Preoperative and postoperative variables, complications, early urinary continence rate(Return of urinary continence status was defined as using no more than one safety pad per day) and oncological outcomes of patients were recorded. Results:All 60 surgeries were successfully completed without conversions or additional incisions. The median (IQR) total operative time was 200.0(153.8, 236.3) min, the median (IQR) console operating time was 107.5(90.0, 150.0) min and the median (IQR) estimated blood loss was 50.0(50.0, 100.0) ml. Positive surgical margins were detected in five patients (8.3%). The continence rate was 43.1%(22/51), 64.7%(33/51), 92.0%(46/50) and 98.0%(49/50), and the PSA undetectable rate was 94.6%(48/51), 98.2%(49/51), 96.6%(47/50) and 100%(50/50) at the 1, 3, 6, and 12 months after surgery. Only 1(1.7%) patient experienced biochemical recurrence 9 months after surgery. The overall complication rate was 20%, including two cases of acute respiratory distress syndrome, one case of rectal injury, one case of urinary tract injury, two cases of poor wound healing, three cases of incision infection, two cases of urinary tract infection and one case of bladder neck-urethral orifice anastomotic stricture.Conclusions:Perineal single-port robot-assisted radical prostatectomy might be safe and feasible surgical treatments for localized prostate cancer, especially for patients with a history of complex abdominal or pelvic surgery. It also showed advantages in early continence. The anatomical structure of the perineal region should be considered, and the correct incision position should be chosen. Specific incision protection measures should also be used for the incision in this particular area of the perineal region to reduce the risk of perioperative complications.

‍ ObjectiveTo investigate the diagnostic efficacy and optimal cut-off values of alpha-fetoprotein （AFP） and alpha-fetoprotein variant L3 （AFP-L3） in hepatitis B virus （HBV）-related early-stage hepatocellular carcinoma （HCC）. MethodsA total of 1 080 patients with HBV-related HCC （HBV-HCC） who were diagnosed for the first time and not yet treated in The Third Affiliated Hospital of Sun Yat-Sen University from January 2019 to July 2022 were enrolled as HCC group in the study， among whom there were 620 patients with CNLC Ⅰ‍a-‍Ⅱ‍a HCC， and in addition， 346 patients with HBV-related chronic hepatitis B （CHB group） and 293 patients with HBV-related liver cirrhosis （LC group） were enrolled as controls. The diagnostic efficacy of AFP and AFP-L3% in screening for HBV-related early-stage HCC was analyzed， including sensitivity， specificity， and the area under the ROC curve （AUC）. The Mann-Whitney U test was used for comparison of continuous data with skewed distribution between two groups； the Kruskal-Wallis H test was used for comparison between multiple groups， and the Bonferroni method was used for further comparison between two groups. ResultsThe HCC group had significantly higher levels of AFP and AFP-L3% than the CHB group and the LC group （H=542.479 and 418.974， both P<0.001）. In early-stage HCC， AFP and AFP-L3% had an optimal cut-off value of 8.7 ng/mL and 5%， respectively， and AFP alone had the largest AUC of 0.816， with a sensitivity of 66.9% and a specificity of 85.1%. There was no significant difference in AUC between AFP-L3%+AFP and AFP alone （Z=0.609， P=0.543）， but both AFP-L3%+AFP and AFP alone had a significantly larger AUC than AFP-L3% alone （AFP vs AFP-L3%： Z=8.173， P<0.001； AFP+AFP-L3% vs AFP-L3%： Z=8.802， P<0.001）. ConclusionAFP has a good value and is superior to AFP-L3% in the diagnosis of HBV-related early-stage HCC， and the screening cut-off value of AFP should be lowered in order to improve the detection rate of early-stage HCC.

Objective:To examine a new technique of robot-assisted nephroureterectomy without robot reldocking or patient repositioning.Methods:Patients diagnosed as upper tract urothelial carcinoma treated with this modality between November 2015 and January 2019 at Department of Urology, Sir Run Run Shaw Hospital, Zhejiang University School of Medicine were included in this analysis. Data collection including patient demographics, operative procedure and postoperative morbidities were conducted by retrospective charts review, after receiving the institutional review board′s approval. There were 35 males and 27 females with a median age of 70 years (range: 30 to 91 years) underwent single docking robot-assisted nephroureterectomy without repositioning. Among the 62 cases, 37 patients had pelvic carcinoma while 25 patients had ureteral carcinoma (with proximal portion 12 cases, middle portion 5 cases and distal portion 8 cases). The patient was placed in a 60 to 80-degree, modified flank position with a 15-degree Trendelenburg tilt. The contralateral arm was positioned perpendicular to the torso on an arm board while the ipsilateral arm was taped to the patient′s side with ample padding. The robot cart was then docked at a 90-degree angle, perpendicular to the patient. A “W”-shape, three robotic-arm configurations was used for port placement.Results:The surgical procedures were performed successfully in all the 62 patients. The operation time was (171.6±54.7) minutes (range: 60 to 370 minutes). The estimated blood loss during the operation was 50(50) ml (range: 20 to 400 ml) with 4 patients had transfusion. No perioperative death was encountered. Eleven patients had post-operative complications (Clavien-Dindo grade 2) including 3 cases of hemorrhage and 8 cases of chylous leakage. All cases were regularly followed up with a median time of 37 months (range: 17 to 55 months). There were 8, 30, 19, 4 and 1 case followed up for 48, 36, 24, 18 and less than 18 months, respectively. Three patients had reginal recurrences and 11 cases of distant metastasis occurred, with 5 patients died for cancer. The survival rate within 24 months was estimated as 75.4%(43/57).Conclusion:Robot-assisted nephroureterectomy without robot redocking or patient repositioning could be safely reproduced, with surgical outcomes comparable to other established techniques.

Objective To evaluate the changing pattern of pelvic incidence (PI) during peak skeleton growth in adolescence and to study whether PI is associated with the anatomical morphology changes of pelvis and sacrum.Methods This retrospective longitudinal study recruited adolescent idiopathic scoliosis (AIS) patients,age between 9 and 18 years with full spine images and have at least 3 times' follow-up.The radiological anatomical parameters were measured in each follow-up including PI,pelvic height (PH),pelvic width (PW),sacral width (SW),femoral head-sacrum (FH-S),sacrum-coccyx (S-C) length,sacrum-coccyx (S-C) distance and sacral curvature ratio.△Parameter and growth velocity of each parameters were calculated.According to the skeletal maturity,all subjects were divided into 3 groups:Low Risser Group (first visit at Risser 0 and follow up through Risser 0 to 1),Moderate Risser Group (first visit at Risser 1 and follow up through Risser 1 to 3) and High Risser group (first visit at Risser 3 and follow up through Risser 3 to 5).Each group has 106 patients.We increased the male ratio to detect the gender difference.A total of 318 AIS patients were included in our study and there are 117 male patients.Descriptive analysis was conducted on the sample age,gender and measured parameter values with mean and standard deviation (SD).The intra-and inter-observer reliability analysis,and the intraclass correlation coefficient (ICC) were calculated.The correlation between △PI and △parameter was evaluated by calculating Pearson correlation coefficient R value.Results The mean age of all subjects was 12.86 years and the mean Cobb angle was 26.67° at first visit.The peak growth velocity of PI was in Risser I (female 1.5°/year and male 1.6°/year).The PI was also increasing rapidly in Risser 0.5 (female 1.2°/year and male 1.5°/year) and Risser 2 (female 1.1°/year and male 1.4°/year).When the Risser grade reached 3 which was a sign of the end of skeleton growth,the PI still had increasing potential and it increased slower in Risser 4 and Risser 5.There showed significant correlation between △PI and △age in the three group(P＜0.05)and the correlation was stronger in Low Risser group and Moderate Risser group than that in High Risser group.There showed significant correlation between △PW and △PI in all groups while △PH and △PI showed correlation only in Low Risser group.There showed significant correlation between △SW and △PI,△FH-S and △PI,△S-C length and △PI (P＜0.05) except △S-C length in male Low Risser group and △FH-S in female High Risser group and the Moderate Risser group had the strongest correlation.The △S-C distance and △S-C ratio didn't show any correlation with △PI (P＜0.05) expect the male of High Risser group.Conclusion Pelvic incidence is increasing during skeleton growth at the age of 9 to 17.It has the peak growth velocity in Risser 1 and remains growth potential in Risser 5.PI growth is correlated with pelvic height,femoral head-sacrum distance,pelvic width and sacral width.

Objective To discuss the feasibility,safety and efficacy of robot-assisted laparoscopic buccal mucosal ureteroplasty in the treatment of long segment upper ureteral stricture.Methods Five patients with complex ureteral strictures were treated with robot-assisted laparoscopic buccal mucosa ureteroplasty (5 males;right side,2 cases;left side,3 cases) in our hospital from March to July of 2017.The patients aged 25-40 years with median of 35 years old.The median body mass index was 23.5 kg/m2 (19-29 kg/m2).Data of surgical conditions,postoperative complications,and follow-up were collected.Results All patients were treated with robot-assisted laparoscopic buccal mucosa ureteroplasty and the operations were uneventful.The median length of stricture of upper ureter were 3 cm (2-6 cm).The median operation time was 360 min (200-400 min),median blood loss was 100 ml (50-200 ml),drainage tube retained time was 5 d(2-9 d),post-operative hospital stay was 11 d(7-12 d),and the median creatinine value was 85 μmol/L (76-98 μmol/L).No urine leakage,infection,buccal mucosa necrosis or other serious complications occurred after surgery.Five patients' CT examnation showed improved hydronephrosis 3 weeks post-operatively.DJ stent was removed 3 months after surgery in 2 patients,and 1 patient presented with no hydronephrosis,another one with mild hydronephrosis.DJ stent was removed 6 months after surgery in the other 3 patients with improved hydronephrosis.Conclusions Robot-assisted laparoscopic buccal mucosal ureteroplasty for the treatment of long segment upper ureteral stricture is a safe and feasible procedure,with a good short-term effectiveness and without severe complications.

Objective To investigate whether initial intervention based on WBC measured within 2 hours postoperatively can reverse the uroseptic shock induced by UUTEL.Methods From May,2015 to July 2015,24 female New Zealand rabbits,weighing 2.0-2.5 kg,born 2-3 months,used as uroseptic shock model.Their ureters were ligated and followed by injection of Escherichia coli solution into the renal pelvis.Then,those animals were randomly assigned into control group(the first group)and experimental groups (the second group,the third group).Each group had 8 rabbits initially.The first group did not receive sensitive antibiotic or fluid resuscitation.The second group received imipenem and cilastatin sodium 15mg/kg and normal saline 5 ml/kg 2 hours postoperatively.The third group received sensitive antibiotic and fluid resuscitation the same dosage as the second group 6 hours postoperatively.Mean arterial pressure(MAP) was recorded for 10 hours and survival rate of all groups for 72h postoperatively was recorded..The clinical data of 46 patients whose WBC count less than 2.85 × 109/L within two hours after UUTEL were analyzed retrospectively.These patients were divided into two groups based on the time of intervention.Group A including 19 patients received routine antibiotic,fluid therapy,low-dose corticosteroids when there was symptom of shock.Group B including 27 patients immediately received resuscitation bundle protocol when there was a drastic decrease in WBC.The incidence of septic shock,the rate of intubation,length of stay in ICU,length of stay in hospital postoperatively,hospitalization cost and survival rate of these two groups were compared.Results All 8 rabbits of the first group died within 72 h,postoperatively and the median time of survival was 11 h.None of the second group rabbits developed shock and all rabbits survived 72 h after operation.6/8 rabbits of the third group survived 72 h after operation.15 patients in Group A and 3 patients in Group B experienced acute uroseptic shock (P ＜ 0.05).11 patients in Group A and one patients in Group B underwent tracheal intubation (P ＜ 0.05).18 patients in Group A and 6 patients in Group B were transferred to ICU(P ＜ 0.05),and their length of stay in ICU was (10.8 ± 5.4) d and (7.5 ± 2.8) d,respectively(P ＞ 0.05).The length of stay in hospital and hospitalization cost of Group A and B were (19 ± 9.8)d vs.(7 ±4.7)d(P ＜0.05),(94 583 ±51 623) RMB vs.(35 389 ± 16 342) RMB respectively (P ＜ 0.05).One patient in Group A died due to acute uroseptic shock and none of Group B died.Conclusions Our animal model and clinical cohort study showed that initial intervention based on WBC mneasured within 2 hours postoperatively can reverse the uroseptic shock induced by UUTEL and improve the prognosis.
