Abstract
A 62-year-old female patient presented with binocular vision loss for 10 days. Fundus photography and optical coherence tomography showed bilateral optic disc edema. Fundus fluorescein angiography showed hypofluorescence of the optic disc in the early stage, but irregular filling defects and segmental hyperfluorescence in the late stage. The diagnosis of bilateral simultaneous non-arteritic anterior ischemic optic neuropathy was made. The patient's visual acuity and visual field were improved after the use of megadose corticosteroids and comprehensive treatment. The prognosis of the patient was stable during the follow-up period.

Abstract
The study investigated the clinical value of fluorescence cholangiography using indocyanine green (ICG) in laparoscopic cholecystectomy (LC) and laparoscopic common bile duct exploration (LCBDE) in preventing bile duct injury (BDI) and detecting bile leakage. A total of 300 patients who underwent fluorescent navigation LC and LCBDE in the Second Department of General Surgery, Shengjing Hospital Affiliated to China Medical University from June 2020 to September 2022 were selected as the research objects for observation and analysis. There were 114 males and 186 females, and aged (50.7±14.0) years with the body mass index (BMI) of (23.6±1.6) kg/m². All 300 cases of fluorescence navigation surgery were successfully completed, of which 5 patients received fluorescence-guided LCBDE and primary suture. The results showed that the application of fluorescence cholangiography with ICG can effectively avoid and detect the occurrence of BDI and bile leakage. Meanwhile, it is reasonable to hypothesize that ICG can be used for rapid localization and the final check to prevent the recurrence of bile leakage when bile leakage is suspected in the second operation.

Abstract
Objective: To establish a predictive model for upper urinary tract damage in children with neurogenic bladder and verify its efficacy. Methods: From January 2011 to December 2021, 143 children with NB in the Children's Hospital of Chongqing Medical University and 84 children with NB in the First Affiliated Hospital of Zhengzhou University were selected as the research objects. The former is set as the training set and the latter is set as the validation set, and the general parameters of the two are compared. The independent risk factors of upper urinary tract damage in children with NB were screened out by Lasso regression, and multivariate logistic regression analysis and a nomogram prediction model was established. The models were validated internally and externally on the training set and validation set, respectively, and the area under the receiver operating curve (ROC) was used to verify the accuracy of the model. Results: A total of 227 children with NB were included in this study, including 121 males and 106 females, aged (10.2±3.8) years. There was no significant difference in other parameters except age between the training set and validation set (all P>0.05); Lasso regression and multivariate logistic regression analysis showed that detrusor leakage point pressure (DLPP) ≥ 40 cmH2O (OR=4.76, 95%CI: 2.01-11.26, 1 cmH2O=0.098 kPa), overactive bladder (OAB) (OR=3.08, 95%CI: 1.34-7.04), bladder compliance (BC)<20 ml/cm H2O (OR=3.65, 95%CI: 1.41-9.47), history of previous urinary tract infection (OR=2.73, 95%CI: 1.09-6.81), and abdominal pressure/other voiding patterns (OR=2.86, 95%CI: 1.20-6.82) were risk factors for upper urinary tract damage in children with NB (all P<0.05). The above parameters were used to establish a nomogram model of upper urinary tract damage in children with NB. The internal and external validation results show that the AUC values for the training and validation sets were 0.84 (95%CI: 0.77-0.91) and 0.86 (95%CI: 0.79-0.94), respectively. Conclusion: The prediction model of upper urinary tract damage in children with NB constructed in this study has high discrimination, accuracy and clinical applicability, which can help clinicians identify high-risk patients and make individualized treatment design for these patients.

Abstract
Objective: To evaluate the efficacy of in-situ full size split liver transplantation(fSLT) for adult recipients using the living donor liver transplantation(LDLT) technique and to compare the characteristics of the left hemiliver graft (LHG) and the right hemiliver graft(RHG)transplantation. Methods: Deceased donor and recipient data of 25 consecutive cases of fSLT at Department of Hepatopancreatobiliary Surgery, Ningbo Medical Center Lihuili Hospital from March to December 2021 was retrieved and the patients divided into two groups:LHG group and RHG group. Among the 13 donors,11 were male and 2 were female,aged (M(IQR))38(19) years(range: 25 to 56 years),with height of 168(5) cm(range:160 to 175 cm) and weight of 65(9) kg(range: 50 to 75 kg). The median age of the 25 recipients was 52(14) years(range:35 to 71 years),17 were male and 8 were female,15 had primary liver cancer and 10 had benign end-stage liver disease,model for end-stage liver disease score was 10(9) points(range:7 to 23 points). Of the 25 recipients,10 recipients had previously undergone hepatobiliary surgery. The follow-up period was to January 2022. Demographic,clinicopathological,surgical outcomes and postoperative complications were evaluated and compared between the two groups. Continuous quantitative data were compared using Mann-Whitney U test. Classification data were expressed as frequencies,and were compared between groups using χ2 test or Fisher exact probability method. Results: Using LDLT technique,in-situ full-left/full-right liver splitting was performed and 13 viable pairs of hemiliver grafts were harvested with acquisition time of 230(53) minutes(range:125 to 352 minutes) and blood loss of 250(100) ml(range:150 to 1 000 ml). A total of 25 hemiliver grafts(13 LHG and 12 RHG) were allocated to patients listed for liver transplantation in our center by China Organ Transplant Response System. In the LHG group(13 cases),there were more females and more patients with benign end-stage liver disease than in the RHG group(12 cases)(P<0.05). The body weight and graft weight of recipients in the LHG group were lower than that in RHG group(both P<0.05). There were no significant differences in other baseline data between the two groups(all P>0.05). The graft to recipient weight ratio(GRWR) was 1.2(0.4)%(range:0.7% to 1.9%) for 25 recipients,1.1(0.5)%(range:0.7% to 1.6%)for the LHG group and 1.3(0.5)%(range:0.9% to 1.9%)for the RHG group. There was no significant difference between the two groups (P>0.05). Sharing patterns of hepatic vessels and the common bile duct are as follows:all the trunk of middle hepatic vein were allocated to the LHG group. The proportion of celiac trunk,main portal vein and common bile duct assigned to LHG and RHG was 10∶3 (P=0.009), 9∶4 (P>0.05) and 4∶9 (P=0.027),respectively. The vena cava of 12 donors in early stage retained in LHG and that of last one was shared between LHG and RHG (P<0.01). The median cold ischemia time of 25 hemiliver grafts was 240(90) minutes(range:138 to 420 minutes). For the total of 25 fSLT,the median anhepatic phase was 50(16) minutes(range:31 to 98 minutes) and the operation time was 474(138)minutes(range:294 to 680 minutes) with blood loss of 800(640) ml(range:200 to 5 000 ml). There were no significant differences in all of operation data between two groups. In the LHG group,3 patients with GRWR≤0.8% had postoperative small-for-size syndrome which improved after treatment. Postoperative Clavien-Dindo grade≥Ⅲ complications were observed in 6 cases(24.0%),4 cases(4/13) in the LHG group and 2 cases(2/12) in the RHG group,respectively. The difference was not statistically significant. Among them,5 cases improved after re-operation and intervention,1 case in LHG group died of secondary infection 2 weeks after operation,and the mortality was 4.0%. Analysis of serious postoperative complications and death has suggested that conventional caval interposition should not be used for LHG transplantation. Conclusion: Relying on accurate donor-recipient evaluation and the apply of LDLT technique,the morbidity and mortality of in-situ fSLT in adults is acceptable.

Abstract
The purpose of this study was to investigate the injury of aspirin and clopidogrel on small intestinal mucosa in rats and the protective effect of teprenone. The study found that aspirin and clopidogrel could cause intestinal mucosal injury in rats, which was even worse with dual drugs. The mechanism of mucosal injury included free radical injury induced by aspirin and decreased synthesis of vascular endothelial growth factor (VEGF) by clopidogrel. Teprenone may repair intestinal mucosa via boosting VEGF level.

Abstract
Objective: To analysis the curative effect of emergency cholecystectomy (EC) and percutaneous transhepatic gallbladder drainage (PTGBD) followed by delayed cholecystectomy (DC) on the patients with moderate acute cholecystitis. Methods: The perioperative dataof patients in EC group (n=47) and in PTGBD-DC group (n=49) were compared retrospectively. Results: Compared to PTGBD+ DC group, EC patients had a significantly more postoperative abdominal drainage time [(9.0±12.9) vs (3.4±2.1) days, P=0.041], more postoperative hospital stay after cholecystectomy [(8.2±3.2) vs (5.1±1.8) days, P=0.004], more intraoperative bleeding [(101±125) vs (33±37) ml, P=0.003], more patients of LC conversion to open cholecystectomy (OC) (19.1% vs 4.1%, P=0.021) and more patients of OC(14.9% vs 0, P=0.005). Also, there were higher incidence of respiratory failure(14.8% vs 2.0%, P=0.029), and admission for ICU(21.3% vs 2.0 %, P=0.003). Also, patients of total OC in non-biliary surgeons group were more than that of biliary surgeons group statistically(63.2% vs 14.3 %, P=0.001). Conclusion: PTGBD followed by DC in the treatment of moderate acute cholecystitis was better than EC, especially in patients with complicated comorbidities and in non-biliary surgeons.

Abstract
Objective: To explore the feasibility and effectiveness of the two-point traction with guidewire method to improve the safety of percutaneous transhepatic sinus tract dilation. Methods: The clinical data of 18 patients underwent the two-point traction guided by percutaneous transhepatic sinus dilation between January 2013 and July 2017 in Shengjing Hospital of China Medical University were analyzed retrospectively. The operation time, volume of intraoperative blood loss and postoperative complications were recorded. Results: All of the 18 patients were treated successfully. The mean size of the percutaneous transhepatic sinus tract was (18.6±2.3) Fr. The operation time was 15-45 min, with an average of 30 minutes, and the average intraoperative blood loss was about 11.7 ml. The incidence of postoperative complications was 22.2% (4/18), including cholangitis in 3 patients, pancreatitis in 1 case. All the complications were relieved after symptomatic treatment, no severe complications (biliary tract perforation or severe haemorrhage) occurred. A total of (3.3 ± 2.6) times cholangioscopic explorations for stone extraction were performed, with a overall clearance rate of 64.7% (11/17). Conclusions: From the results of limited patient data in this group, the two-point traction with guidewire can provide the exact guidance for percutaneous transhepatic sinus tract dilation, which is effective and easily conducted, but still need further clinical study to confirm.

Abstract
Objective: To discuss the preliminary experience of single incision laparoscopic colorectal surgery. Methods: The clinical data and surgical outcomes of 104 selected patients who underwent single incision laparoscopic colorectal surgery in the 2nd Department of General Surgery, Shengjing Hospital of China Medical University from January 2010 to September 2015 were retrospectively analyzed. There were 62 male and 42 female patients, aging from 21 to 87 years with a mean of (61±12) years. Eighty-five patients were diagnosed with malignancy while the rest 19 cases were benign diseases. All the procedures were performed by the same surgeon using the rigid laparoscopic instruments. Surgical and oncological outcomes were analyzed in 4 kinds of procedures which are over 5 cases respectively, including low anterior resection, abdominoperineal resection, radical right colon resection and radical sigmoidectomy. Results: Single incision laparoscopic colorectal surgery was performed in 104 selected patients and was successfully managed in 99 cases with a total conversion rate of 4.8%. Radical procedures for malignancy in cases with the number of patients more than 5 were performed for 74 cases. For low anterior resection, 35 cases with an average surgical time of (191±57) minutes, average estimated blood loss of (117±72) ml and average number of harvested lymph nodes of 14.6±1.1. For abdominoperineal resection, 9 cases with an average surgical time of (226±54) minutes, average estimated blood loss of (194±95) ml and average number of harvested lymph nodes of 14.1±1.5. For radical right colon resection, 16 cases with an average surgical time of (222±62) minutes, average estimated blood loss of (142±68) ml and average number of harvested lymph nodes of 15.4±2.4. For radical sigmoidectomy, 14 cases with an average surgical time of (159±32) minutes, average estimated blood loss of (94±33) ml and average number of harvested lymph nodes of 13.9±1.5. The overall intraoperative complication rate was 2.7% (2 cases) and postoperative complication rate was 8.1% (6 cases) in these 74 cases. Conclusion: Single incision laparoscopic colorectal surgery is safe and feasible with acceptable surgical outcomes and cosmetic benefits in the hands of skilled laparoscopic surgeon in well-selected patients.

Abstract
Microtwins and stacking faults in plastically deformed aluminum single crystal were successfully observed by high-resolution transmission electron microscope. The occurrence of these microtwins and stacking faults is directly related to the specially designed crystallographic orientation, because they were not observed in pure aluminum single crystal or polycrystal before. Based on the new finding above, we propose a universal dislocation-based model to judge the preference or not for the nucleation of deformation twins and stacking faults in various face-centered-cubic metals in terms of the critical stress for dislocation glide or twinning by considering the intrinsic factors, such as stacking fault energy, crystallographic orientation, and grain size. The new finding of deformation induced microtwins and stacking faults in aluminum single crystal and the proposed model should be of interest to a broad community.

Abstract
Catestatin (bCGA(344-364)), an endogenous peptide of bovine chromogranin A, was initially characterized for its effect on the inhibition of catecholamine release from chromaffin cells. Catestatin and its active domain (bCGA(344-358)) were identified in chromaffin cells and in secretion medium. The present study identified a potent antimicrobial activity of bCGA(344-358) in the lowmicromolar range against bacteria, fungi and yeasts, without showing any haemolytic activity. Confocal laser microscopy demonstrated penetration of the rhodaminated peptide into the cell membranes of fungi and yeasts and its intracellular accumulation. Time-lapse videomicroscopy showed arrest of fungal growth upon penetration of the labelled peptide into a fungal filament. We identified several catestatin-containing fragments in the stimulated secretion medium of human polymorphonuclear neutrophils, suggesting the N-terminal sequence of catestatin (bCGA(344-358)) (named cateslytin) as a novel component of innate immunity.

Abstract
AIM To investigate the demethylated metabolites of roxithromycin (RXM) in humans and rats, and to study the antibiotic activity of these metabolites in vitro. METHODS The demethylated metabolites of RXM in humans and in rats were identified by liquid chromatography-mass spectrometry (LC-MS), and the in vitro antibiotic activities of them against three standard strains were also studied compared with those of the parent drug and some other metabolites of RXM. RESULTS O-Demethylation of RXM was one of the main metabolic routes of RXM in humans, whereas N-demethylation metabolism was more predominant in rats. O-Demethyl-RXM appeared to be equally effective with RXM. CONCLUSION The O-demethyl-RXM was an active metabolite in humans, and there were some species differences in RXM demethylation metabolism between humans and rats.

Abstract
Nuclear receptor coactivators associate in a ligand-dependent manner with estrogen receptors (ER) and other nuclear receptors, and they enhance ligand-dependent transcriptional activation. This study examined basal coactivator expression in rat uterus to investigate if expression of these genes is regulated by estradiol-17 beta or tamoxifen. Ovariectomized mature and immature rats were injected with estradiol-17 beta, tamoxifen, or vehicle (i.e., sesame oil) alone. Uteri were collected and analyzed for changes in coactivator mRNA expression using Northern blot and in situ hybridization analyses. Constitutive uterine mRNA expression of switch protein for antagonist (SPA), SRC-1, GRIP1, RAC3, RIP140, and p300 mRNAs was observed in control uteri, and treatment with ER ligands did not alter coactivator mRNA levels. The data suggest that expression of these coactivator genes is not sensitive to estradiol or tamoxifen in the rat uterus. No cell type-specific pattern of expression was apparent in uterine sections from mature and immature rats; however, silver grains were more abundant in luminal and glandular epithelial cells compared with the stroma and myometrium, indicating that coactivator mRNA levels vary among the uterine compartments. Thus, to our knowledge, we show for the first time that there is constitutive expression of several uterine nuclear receptor coactivators in a physiological setting that remains insensitive to estrogenic regulation. Furthermore, we speculate that higher constitutive levels of coactivator expression in glandular and luminal epithelial cells may be associated with increased hormonal responsiveness by these uterine compartments.
