Objective To investigate the effect of intrarectal local anesthesia (IRLA) with heated oxybuprocaine gel on pain during transrectal ultrasound guided prostate biopsy (TRUSPB).Methods A total of 150 cases patients who underwent TRUSPB in Huzhou Central Hospital from January to June 2023 were prospectively taken into.The patients were randomly divided into group A (routine group),group B (oxybuprocaine gel for IRLA at room temperature) and group C (oxybuprocaine gel for IRLA at 40℃),with 50 cases in each group.Nurses who were unaware of the anesthesia type used visual analog scale (VAS) to score the pain level of patients at each stage (VAS Ⅰ:when the ultrasound probe was inserted into the rectum;VAS Ⅱ:during the biopsy;VAS Ⅲ:30 minutes after biopsy),and the incidence of complications after biopsy were compared.Results The VAS Ⅱ score of group C was lower than that of group A and group B,and the difference was statistically significant (P<0.05).There was no statistically significant difference (P>0.05) in the VAS Ⅰ,VAS Ⅲ scores,and incidence of complications after biopsy among the three groups.There was no allergic reaction to oxybuprocaine gel.Conclusion In TRUSPB,IRLA with heated oxybuprocaine gel can effectively control pain without increasing incidence of complications.

Objective To monitor the susceptibility of clinical isolates to antimicrobial agents in tertiary hospitals in major regions of China in 2022.Methods Clinical isolates from 58 hospitals in China were tested for antimicrobial susceptibility using a unified protocol based on disc diffusion method or automated testing systems.Results were interpreted using the 2022 Clinical &Laboratory Standards Institute(CLSI)breakpoints.Results A total of 318 013 clinical isolates were collected from January 1,2022 to December 31,2022,of which 29.5％were gram-positive and 70.5％were gram-negative.The prevalence of methicillin-resistant strains in Staphylococcus aureus,Staphylococcus epidermidis and other coagulase-negative Staphylococcus species(excluding Staphylococcus pseudintermedius and Staphylococcus schleiferi)was 28.3％,76.7％and 77.9％,respectively.Overall,94.0％of MRSA strains were susceptible to trimethoprim-sulfamethoxazole and 90.8％of MRSE strains were susceptible to rifampicin.No vancomycin-resistant strains were found.Enterococcus faecalis showed significantly lower resistance rates to most antimicrobial agents tested than Enterococcus faecium.A few vancomycin-resistant strains were identified in both E.faecalis and E.faecium.The prevalence of penicillin-susceptible Streptococcus pneumoniae was 94.2％in the isolates from children and 95.7％in the isolates from adults.The resistance rate to carbapenems was lower than 13.1％in most Enterobacterales species except for Klebsiella,21.7％-23.1％of which were resistant to carbapenems.Most Enterobacterales isolates were highly susceptible to tigecycline,colistin and polymyxin B,with resistance rates ranging from 0.1％to 13.3％.The prevalence of meropenem-resistant strains decreased from 23.5％in 2019 to 18.0％in 2022 in Pseudomonas aeruginosa,and decreased from 79.0％in 2019 to 72.5％in 2022 in Acinetobacter baumannii.Conclusions The resistance of clinical isolates to the commonly used antimicrobial agents is still increasing in tertiary hospitals.However,the prevalence of important carbapenem-resistant organisms such as carbapenem-resistant K.pneumoniae,P.aeruginosa,and A.baumannii showed a downward trend in recent years.This finding suggests that the strategy of combining antimicrobial resistance surveillance with multidisciplinary concerted action works well in curbing the spread of resistant bacteria.

Endoscopic anterior fundoplication with the MUSE is an endoscopic therapy that combines ultrasound and endoscopic anti-reflux technology for moderate to severe gastroesophageal reflux disease. Training and learning procedures are required to obtain qualifications for this endoscopic therapy before clinical operations. At present, there is limited high-quality evidence-based medical evidence on MUSE treatment, and lack of expert consensus or guidance for training and the standard of MUSE therapy procedure. This consensus is based on the published literature, and formulated by experts with MUSE clinical experience in China, to provide guidance for the training and clinical standard operation of this technique.

Objective:To investigate the predictive value of preoperative lymphocyte-to-monocyte ratio (LMR) combined with platelet-to-lymphocyte ratio (PLR) (LMR-PLR) scoring model for prognosis of pancreatic ductal adenocarcinoma (PDAC) after radical resection.Methods:The retrospective cohort study was conducted. The clinicopathological data of 116 patients with PDAC who were admitted to the Second Hospital of Lanzhou University from January 2015 to December 2019 were collected. There were 73 males and 43 females, aged 61.5(range, 29.0-75.0)years. All patients underwent radical resection for PDAC. Observation indicators: (1) optimal cut-off value of LMR and PLR; (2) clinicopathological features of patients with different scores of preoperative LMR-PLR scoring model; (3) follow-up and survival; (4) influencing factors for prognosis of PDAC patients; (5) construction and verification of nomogram prediction model. Measurement data with skewed distribution were represented as M(range). Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test. Comparison of ordinal data was conducted using the Mann-Whitney U test. The Graphpad prism 8 was used to draw survival curve, the Kaplan-Meier method was used to calculate survival rate, and the Log-Rank test was used for survival analysis. The COX proportional hazard regression model was used for univariate and multivariate analyses. The X-tile software was used to determine the optimal cut-off values of LMR and PLR. The nomogram prediction model was conducted based on the results of multivariate analysis, and the receiver operating characteristic (ROC) curve was drawn. The area under curve (AUC) was used to evaluate the discrimination of nomogram prediction model. The calibration curve was used to evaluate the consistency of nomogram prediction model and the decision curve was used to evaluate the clinical benefits. Results:(1) Optimal cut-off value of LMR and PLR. The optimal cut-off values of LMR and PLR were 1.9 and 156.3. (2) Clinicopathological features of patients with different scores of preoperative LMR-PLR scoring model. Cases with LMR-PLR scoring as 0, 1, 2 were 11, 42, 63. Cases with CA125 <12.4 U/mL, cases postoperative with vascular invasion, cases with postoperative chemotherapy in patients with 0, 1, 2 of LMR-PLR scoring were 1, 8, 24, 9, 27, 27, 3, 26, 43, showing significant differences among them ( χ2=6.73, 8.37, 6.68, P<0.05). (3) Follow-up and survival. All 116 patients were followed up for 39(range, 2-86)months. The 1-, 2-, 3-year survival rate of 116 PDAC patients was 50.9%, 37.9%, 19.3%, respectively, with a survival time of 13(range, 1-85)months. The survival time of patients with LMR-PLR scoring as 0, 1, 2 was 3(range, 1-9)months, 7(range, 2-56)months, 26(range, 2-85)months, respectively, showing a significant difference among them ( χ2=48.78, P<0.05). (4) Influencing factors for prognosis of PDAC patients. Results of multivariate analysis showed that carcinoembryonic antigen (CEA), CA19-9, LMR-PLR score, tumor diameter were independent factors affecting prognosis of patients ( hazard ratio=1.61, 1.88, 0.27, 1.87, 95% confidence interval as 1.02-2.54, 1.18-3.00, 0.19-0.39, 1.13-3.09, P<0.05). (5) Construction and verification of nomogram prediction model. The nomogram prediction model was constructed based on CEA, CA19-9, LMR-PLR score and tumor diameter. The AUC of ROC curve in predicting 1-, 2-, 3-year survival rate of patients was 0.86 (95% confidence interval as 0.79-0.93, P<0.05), 0.86 (95% confidence interval as 0.79-0.92, P<0.05), 0.87 (95% confidence interval as 0.78-0.95, P<0.05), respectively. Results of calibration curve showed that the predicted survival rate of nomogram prediction model was consistent with the actual survival rate, with the consistency index as 0.74. Results of decision curve showed that the predictive performance of nomogram prediction model was superior to that of a single factor at a risk threshold of 0.12-0.85. Conclusions:CEA, CA19-9, LMR-PLR score, tumor diameter are independent factors affecting prognosis of patients undergoing radical resection for PDAC, and the nomogram prediction model can predict postoperative survival rate. The predicted survival rate of nomogram prediction model is consistent with the actual survival rate, and the predictive performance of nomogram prediction model is superior to that of a single factor at a risk threshold of 0.12-0.85.

Objective:To obtain the parameters associated with hematoma morpholoy by finite element analysis(FEA) and investigated their performance on predicting and diagnosis hematoma expansion(HE) in patients with spontaneous intracrebral hemorrhage(SICH).Methods:Patients with SICH who met research criteria were retrospective enrolled between June 2015 and December 2017. Clinical parameters on admission were collected, Perform 2 independent methodology on same patient to analysis the hematoma shape base on computed tomography(CT): Clinical routine method that performed by clinical investigator to identified margin irregularity of hematoma by CT ,and calculated the volume of hematoma by simplify Tada formula(ABC/2);The FEA method performed by FEA investigator and gain the hematoma 3 dimensional morphology and variables, include Volume, Surface area, and The quantity of triangles per square milimet surface(TQOT/mm 2). The HE was defined as volume enlargement of >33% compared with that on addmission. All patients were divided into HE and none HE group ,respectively, ABC/2 and FEA generated thire own HE and none HE group as different volume calcuation. The HE risk factors of ABC/2 and FEA were assessed in univariate and multivariable Logistic regression models. and the risk fators diagnosis value for HE were determined by the receiver operating characteristic(ROC) curves. Results:Total of 127 patients were enrolled, The mean time of symptom onset to hospital admitted was 3.08±1.34 h. There were 34(26.77%) cases HE identifed by ABC/2 and 31(24.41%)by FEA. Althought there are significant different (pearson χ2=53.66, P<0.01) of HE identification between ABC/2 and FEA, the 2 methods has moderate consistency (Kappa=0.65). All patients’ hematoma 3D reconstruction were performed by FEA and general observation show that TQOT/mm 2 most likely correlate to irregularity of hematoma 3D shape. Multivariable Logistic regression models indicated that ICH score( OR=1.79, 95% CI:1.19~2.68)was independent HE risk factor for ABC/2, respectively, TQOT/mm 2≥1.95/mm 2 ( OR=16.99,95% CI:5.98~48.33)and Ultraearly Hematoma Growth,(uHG) ( OR=1.05, 95% CI:1.01~1.09)were independent HE risk factor for FEA. With ROC analysis, both the ICH score of ABC/2 and uHG of FEA have low HE predictive and diagnosis value ,the area under the curve (AUC) were 0.64 and 0.67 respectively. However, TQOT/mm 2 was found to have excellent diagnosis value (AUC:0.9), sensitivity and specificity were 77% and 83% when the cut-off value was 1.95. Panel parameter model (TQOT/mm 2+uHG) was not be found to have a significant higher AUC than single parameter on FEA and the clinical routine parameters panel model (ICH +SB P>180 mmHg on addmission) have a unacceptable AUC(<0.7) as well as single parameters. Conclusions:Hematoma shape could be reconstructed and analysis by FEA and TQOT/mm 2 was likely relevance to hematoma morphology. TQOT/mm 2≥1.95 was indicate to have a better HE predicting and diagnosis value than any other risk factors and clinical parameters panel models in our reaserch.

[Summary] To explore the therapeutic effect of fecal microbiota transplantation (FMT) for severe psoriasis. A patient, male, 36 years old, diagnosed as severe plaque psoriasis for 10 years and irritable bowel syndrome (IBS) for 15 years, was administrated twice FMT via both upper endoscopy and colonoscopy with a 5‐week interval. The following items were used to evaluate responses: body surface area (BSA), psoriasis area and severity index (PASI), dermatology life quality index (DLQI), histological examination, intestinal symptoms, adverse reactions and serum level of tumor necrosis factor (TNF)‐α. After second FMT treatment for 5 weeks, aforementioned items were improved greatly compared with those before treatment. Moreover, IBS was completely relieved and no adverse reactions were observed during the treatment and follow‐up. In conclusion, FMT could be a novel therapy for psoriasis. Further clinical trials are needed to provide solid evidences.

OBJECTIVE: To study the effects of the overexpression of autophagy-related gene 3 (ATG3) on autophagy and salinomycin-induced apoptosis in breast cancer cells and explore the underlying mechanisms. METHODS: We used the lentivirus approach to establish a breast cancer cell line with stable overexpression of ATG3. Western blotting, immunofluorescence staining and transmission electron microscopy were used to analyze the effect of ATG3 overexpression on autophagy in breast cancer MCF-7 cells. Using the AKT/mTOR agonists SC79 and MHY1485, we analyzed the effect of AKT/mTOR signal pathway activation on ATG3 overexpression-induced autophagy. Western blotting and flow cytometry were used to analyze the effect of autophagy on apoptosis of the ATG3-overexpressing cells treated with salinomycin and 3-MA (an autophagy inhibitor). RESULTS: In ATG3-overexpressing MCF-7 cells, ATG3 overexpression obviously promoted autophagy, inhibited the AKT/mTOR signaling pathway, significantly weakened salinomycin-induced apoptosis ( < 0.01), caused significant reduction of the levels of the pro-apoptotic proteins cleaved-caspase 3 ( < 0.01) and Bax ( < 0.05), and enhanced the expression of the anti-apoptotic protein Bcl-2 ( < 0.05). The inhibition of autophagy obviously weakened the inhibitory effect of ATG3 overexpression on salinomycin-induced apoptosis. CONCLUSIONS ATG3 overexpression promotes autophagy possibly by inhibiting the AKT/mTOR signaling pathway to decrease salinomycin-induced apoptosis in MCF-7 cells, suggesting that autophagy induction might be one of the mechanisms of drug resistance in breast cancer cells.

Objective To evaluate the feasibility and safety of the robot - assisted system YunSRobot for remote manipulation endoscopy. Methods When the master of YunSRobot was installed in the gastroenterology office in Chinese PLA General Hospital, the robot slave and upper gastrointestinal simulation model (Takahashi Lm103,Japan) were installed at the same time in the State Key Laboratory of Robotics, Shenyang Institute of Automation. Three physicians were trained to operate the master robotics and performed gastroscopy on the simulation model based on network cloud. Each physician performed 3 procedures of oesophagogastroduodenoscopy (EGD) by YunSRobot using traditional manual endoscopy, on-site operating mode, and remote manipulation mode, respectively. The operating time, lumenal anatomic exposure,man-machine interaction and other parameters were recorded. Results The number of standard pictures obtained by traditional manual endoscopy group, on-site operating group and remote manipulation group were 39.9±0.3, 39.8±0.4, 39.9±0.3, respectively. The images of all five lesions could be obtained by each operation. The operating time in the duodenum of remote group was longer than that of on-site group, with average time (78.2±16.0)s vs. (68.9±15.8)s (P=0.021) respectively. As to the operating time on other parts or total time, all three groups were comparable. Although there was a mean delay of (572.1±48.5) ms in remote operation group, the operation was still smooth. However, compared with on-site group, the percentage of clear view time in the duodenum was significantly shortened in remote group: [(77.8±8.2)% vs. (83.9 ± 6.4)% , P=0.024]. Statistically significant difference was detected in percentage of clear view time neither in other sites, nor was in the total operating time between two groups. The operating time in each part of remote group was obviously longer than that of manual group as followings, pharyngeal (27.3±4.2) s vs. (9.2±1.3)s (P<0.001), esophageal (29.7±6.4)s vs. (19.3±1.6)s (P=0.004), stomach (56.7±17.0)s vs. (40.3±7.0)s (P=0.003), pylorus (20.2±5.5)s vs. (9.3±1.3)s (P<0.001), duodenum (78.2±16.0)s vs. (29.3±5.6)s (P<0.001). Thus the total operating time was also longer in remote group as (559.0±87.2)s vs. (253.1±16.6)s (P<0.001). The respective time in pharynx, esophagus, stomach, pylorus, duodenum, or the overall time was all longer in remote group than that in manual group. Conclusions The soft endoscopy robot YunSRobot has satisfactory safety and stability. Remote upper gastrointestinal endoscopy can be completed based on common network and an endoscope simulation model with smooth operation. The inspection time by YunSRobot robot per part and the overall time are longer than those of manual operation on site, still, remote operating time meets the standard of upper gastrointestinal endoscopy.
