Objective:To explore the predictive value of pre-treatment platelet-to-albumin ratio (PAR) in short-term prognosis of endoscopic treatment for cirrhosis with esophageal and gastric variceal bleeding(EGVB).Methods:By retrospective analysis method, the clinical data of 195 cirrhotic patients with EVGB from January 2019 to April 2022 treatment at Bengbu First People′s Hospital were collected and analyzed. The PAR was calculated according to platelet count and albumin. The independent risk factors that affecting 6-week rebleeding and death were analyzed by univariate and multivariate Cox regression, the receiver operating characteristic (ROC) curve was drawn to evaluate the predictive value of PAR for rebleeding and death, and Kaplan-Meier survival analysis was used to evaluate the rebleeding rate and survival rate of patients with different PAR ratios.Results:Among 195 patients, 36 patients were rebleeding and 159 patients were non-rebleeding within 6 weeks; while 15 cases died and 180 cases survived. The platelet count, PAR in the rebleeding group were lower than those in the non-rebleeding group, the direct bilirubin, triglyceride, alanine transaminase, prothrombin time and mortality in the rebleeding group were higher than those in the non-rebleeding group: 74.0(66.5, 88.8) × 10 9/L vs. 98.0(85.0, 111.0)×10 9/L, 2.48(2.18, 2.78) vs. 3.35(2.81, 4.04), 18.5(14.0, 23.8) μmol/L vs. 16.0(11.0, 20.0) μmol/L, (4.73 ± 2.52) mmol/L vs. (3.94 ± 1.65) mmol/L, 36.0(27.0, 46.0)U/L vs. 21.0(13.3, 33.0)U/L, (14.78 ± 1.63) s vs. (13.47 ± 0.87) s, 36.11%(13/36) vs. 1.26%(2/159), there were statistical differences ( P<0.05). Cox multivariate regression showed that PAR, alanine transaminase were the independent risk factors for the rebleeding ( P<0.05), PAR was the independent risk factor for the death within 6 weeks ( P<0.05). The area under the curve (AUC) of PAR for predicting 6-week rebleeding and death was 0.876, 0.776, the cut-off was 2.94, 2.71, the specificity was 69.8%, 72.2%, the sensitivity was 94.4%, 73.3%, respectively. According to the cut-off of PAR to predict rebleeding, the 6-week rebleeding rate in the PAR≤2.94 group was higher than that in the PAR>2.94 group ( χ2 = 36.88, P<0.01). According to the cut-off of PAR to predict death, the 6-week mortality rate in the PAR≤2.71 group was higher than in the PAR>2.71 group ( χ2 = 16.44, P<0.01). Conclusions:PAR can be used as a predictor for rebleeding and death within 6 weeks of EGVB in cirrhotic patients.

Objective:To evaluate the efficacy and safety of micropulse transscleral cyclophotocoagulation (MP-TSCPC) for refractory glaucoma.Methods:A prospective multicenter observational case series study was conducted.A total of 63 refractory glaucoma patients (67 eyes) who underwent MP-TSCPC treatment were enrolled at Zhongshan Ophthalmic Center, Sun Yat-sen University, Chengdu First People's Hospital (Chengdu Integrated TCM& Western Medicine Hospital), and Changsha Aier Eye Hospital from August 2022 to April 2023.Among these cases, there were 40 eyes (59.7%) with unreduced intraocular pressure (IOP) after glaucoma surgery, 4 eyes (6.0%) with secondary glaucoma after vitrectomy, 2 eyes (3.0%) with secondary glaucoma after keratoplasty, 8 eyes (11.9%) with neovascular glaucoma, 3 eyes (4.5%) with secondary glaucoma due to iridocorneal endothelial syndrome, 6 eyes (9.0%) with primary open-angle glaucoma and 4 eyes (6.0%) with primary angle-closure glaucoma.Best corrected visual acuity (BCVA) was measured using the ETDRS chart and the IOP was measured using the Goldmann applanation tonometry before and 6 months after the surgery.The usage of anti-glaucoma medications before and after surgery and postoperative complications were recorded.Surgical success rate was calculated and surgical success was defined as an IOP reduction of more than 20% from baseline or a reduction in the number of ocular hypotensive medications with no change in IOP.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of Zhongshan Ophthalmic Center, Sun Yat-sen University (No.2022KYPJ225).Written informed consent was obtained from each subject.Results:There was a statistically significant overall difference in IOP at different time points before and after surgery ( F=60.10, P<0.001), and the IOP at different time points after surgery was significantly lower than that before surgery, with statistically significant differences (all at P<0.001).IOP reduction at 6 months after surgery was (43.7±20.7)%.The number of anti-glaucoma medications used postoperatively was 2(0, 3) types, which was significantly less than the 3(2, 3) types used preoperatively ( Z=-2.70, P=0.007).The 6-month postoperative BCVA (LogMAR) was 1.40(0.52, 2.70), which showed no significant change compared to the preoperative 1.40(0.70, 2.70) ( Z=-0.10, P=0.952).The surgical success rate was 83.6%(56/67) at 6 months postoperatively.Postoperative complications included mydriasis (11/67), conjunctival hemorrhage (11/67), mild anterior chamber inflammation (1/67), mild ciliary body detachment (3/67), local choroidal detachment (1/67), and cystoid macular edema (1/67), all of which were reversible after treatment. Conclusions:MP-TSCPC appears to be a safe and effective treatment option for refractory glaucoma.

Oxalate is an organic dicarboxylic acid that is a common component of plant foods.The kidneys are essential organs for oxalate excretion,but excessive oxalates may induce kidney stones.Jupiter micro-tubule associated homolog 2(JPT2)is a critical molecule in Ca2+mobilization,and its intrinsic mecha-nism in oxalate exposure and kidney stones remains unclear.This study aimed to reveal the mechanism of JPT2 in oxalate exposure and kidney stones.Genetic approaches were used to control JPT2 expression in cells and mice,and theJPT2 mechanism of action was analyzed using transcriptomics and untargeted metabolomics.The results showed that oxalate exposure triggered the upregulation of JPT2,which is involved in nicotinic acid adenine dinucleotide phosphate(NAADP)-mediated Ca2+mobilization.Tran-scriptomic analysis revealed that cell adhesion and macrophage inflammatory polarization were inhibited by JPT2 knockdown,and these were dominated by phosphatidylinositol 3-kinase(PI3K)/AKT signaling,respectively.Untargeted metabolomics indicated that JPT2 knockdown inhibited the produc-tion of succinic acid semialdehyde(SSA)in macrophages.Furthermore,JPT2 deficiency in mice inhibited kidney stones mineralization.In conclusion,this study demonstrates that oxalate exposure facilitates kidney stones by promoting crystal-cell adhesion,and modulating macrophage metabolism and in-flammatory polarization via JPT2/PI3K/AKT signaling.

Objective:To evaluate the clinical value of nanopore targeted sequencing (NTS) in pathogens detection in urinary tract by comparing the results of different tests performed on the same urine sample.Methods:The results of NTS and urine culture test collected from 326 patients in the Department of Urology of People's Hospital of Wuhan University from July 2020 to June 2021 were retrospectively analyzed. There were 224 males and 102 females. The average age was (56.88 ± 14.58)years old. χ 2 test and Student’s test and Wilcoxon's sign rank test were used to analyze the differences of the pathogen detection rate, pathogen types results and detection time consuming between NTS and urine culture. The clinical value of the NTS in rapid detection of urinary pathogens was evaluated. Results:Among 326 hospitalized patients, the urinary tract microbes’ detecting rate of NTS was significantly higher than that of urine culture[67.80%(221/326)vs. 23.93%(78/326), χ2=130.25, P<0.01]. The uropathogens detecting rate of NTS was significantly higher than that of urine culture[54.29%(177/326)vs. 23.31%(76/326), χ2=38.95, P<0.01]. The number of urinary tract microbes detected by NTS was significantly higher than that of urine culture ( Z=11.49, P<0.01), the number of uropathogens was significantly higher than that of urine culture ( Z=9.67, P<0.01). The detection time of NTS and urine culture positive samples was (24.29±2.65) h and (49.28±11.30) h, the difference was statistically significant ( t =39.48, P<0.01). The results obtained by using NTS and urine culture were consistent in 135 (41.41%) samples. In 150 (46.01%) samples, NTS could detect the urinary tract microbes while urine culture cannot find, of which 112 cases (34.36%) were uropathogenic. In 27 cases (8.28%), more pathogens were detected by NTS except those from urine culture. In 6 cases (1.84%) re-detecting NTS after antibiotic therapy, the number of reads of primary uropathogen decreased gradually with the growth of colonizing bacteria or opportunistic pathogens appeared in the end. Re-examinations of urine culture could verify the results of NTS detection on admission in 5 cases (1.53%). NTS in 2 cases (0.61%) could cover the uropathogens of subsequent several urine cultures. Conclusions:NTS has the advantages of rapid, sensitive and comprehensive detection of urinary tract infection pathogens. When urine culture is not yet reported or even negative, NTS already has a certain clinical reference value and can be used as an effective supplement to urine culture, which is conducive to the comprehensive judgment of the patient's condition.

Objective:To analyze the operation data of inter-provincial direct settlement of patients with chronic diseases and special diseases in outpatient service, explore the effect of policy implementation and put forward corresponding suggestions.Methods:The descriptive analysis method was used to analyze the real-time settlement data of outpatients with chronic disease and special disease of a grade A tertiary cancer hospital in Beijing in 2022, including changing trend in medical visits, age distribution of the medical population, disease distribution of the medical population, medical departments, cost structure, and payment of medical insurance benefits.Results:In 2022, the hospital admitted a total of 12 812 outpatient patients with chronic and special diseases from 28 provinces and Xinjiang Production and Construction Corps, with an increase from 53 in January to 1 957 in December. The age of the patients was 11 to 88 years old, most of whom were 51 to 70 years old. The main disease was lung cancer, and the main visiting departments were internal medicine(chemotherapy) and radiotherapy(radiotherapy). The cost of diagnosis and treatment was relatively high, and the average proportion of medical insurance fund payment was 79.94%.Conclusions:The inter-provincial direct settlement policy for outpatients with chronic diseases and special diseases could further release the demand for medical treatment, greatly reduce the economic burden of cancer patients, and help to solve the problem of " difficult and expensive medical treatment" for patients with cancer and other major diseases.

Objective To propose on and improve direct settlements by medical insurance offices and hospital systems in their processing of medical treatment in allopatry (MTA), by analyzing such data as the homepages of medical records of such inpatients at a tertiary cancer hospital with their medical expenses settled directly. Methods Data of 6 379 MTA inpatients with direct settlements of in-hospital fees from April 2017 to March 2018 were included in this study. Such data were used to identify the change trend of their case counts and their regional distribution, and analyzed with hierarchical clustering to calculate the settlement counts of various provinces. Results Analyses found that the total cases of such patients remained stable at the hospital, yet the cases of direct settlement rose from five to 1 263, and the proportion of direct settlement among all MTA inpatients rose month by month from 0.14% to 29.26%. Most of MTA inpatients come from Hebei, Shandong, Inner Mongolia and Shanxi provinces in turn, yet the direct settlement counts and hospitalization case trends appear different. Clustering results indicate Hebei as the type-1 province with the highest proportion of direct settlement inpatients, accounting for 30. 41% ;Shandong, Inner Mongolia and Shanxi as the type-2 provinces, accounting for 15. 05% , 13. 45% and 11.00% respectively; Liaoning, Henan and Heilongjiang as the type-3 provinces, accounting for 6.79% , 4.81% and 4.42% respectively; while the rest provinces as the type-4, accounting for less than 3%. Conclusions Regional distribution varies distinctively among such inpatients, and the number of these inpatients keeps rising stably. In such circumstances, hospitals are recommended to enhance their management in strengthening medical insurance audit systems, speeding up settlement, and building regional medical alliances.

Objective: To compare the short-term and long-term outcome between robotic gastrectomy and laparoscopic gastrectomy. Methods: The clinical data of 517 patients who had received robotic gastectomy and laparoscopic gastrectomy between December 2011 and December 2013 at Department of General Surgery, Chinese People′s Liberation Army General Hospital was collected. After propensity score matching, 70 patients in robotic gastectomy and 70 patients in laparoscopic gastectomy were identified. Perioperative outcome and overall survival were compared between the two groups using t test, χ² test, Kaplan-Meier curve and Log-rank test, respectively. Prognosis factors were analyzed by Cox′s proportional hazards regression. Results: There were comparable baseline characteristics between patients in robotic group (RG) and those in laparoscopic group (LG). The conversion rate for RG and LG were 5.7% and 4.3% respectively (P=1.000). Compared with LG, RG had similar lymph node retrieval (25.5±7.2 vs. 24.5±8.3, t=0.770, P=0.443) and less blood loss ((147.0±96.8) ml vs. (188.0±111.2) ml, t=-2.326, P=0.021). There were also similar complications (χ²=0.233, P=0.629) and severity of complications (W=70.500, P=0.053). Although there tended to be early mobility, early flatus and less hospital stay for patients in RG group, the difference between RG and LG was not statistically significant. The 3-year survival rate was 72.9% and 60.0% for patients in RG and patients in LG (P=0.578). Multivariable analysis revealed gender (HR=2.529, 95% CI: 1.042 to 6.140, P=0.040), neoadjuvant chemotherapy (HR=0.272, 95% CI: 0.104 to 0.710, P=0.008) and vascular invasion (HR=2.135, 95% CI: 1.027 to 4.438, P=0.042) were independent prognostic factors. Conclusion Compared with laparoscopic gastrectomy, robotic gastectomy could achieve similar short-term and long-term outcomes.

OBJECTIVETo systemically evaluate the relationship between the expression of insulin-like growth factor receptor type I (IGF-1R) and prognosis in gastric cancer (GC) patients.

METHODSA literature search was conducted from PubMed, EMBASE, Web of Science, CNKI, Wanfang and VIP databases to retrieve the clinical studies relevant to IGF-1R expression and its prognostic value in GC patients. Meta-analysis was performed using STATA 12.0 software. The methodology was assessed according to the European Lung Cancer Working Party Quality Scale for Biological Prognostic Factors for Lung Cancer. The quality of studies was assessed using the Newcastle-Ottawa scale.

RESULTSFour eligible studies including 685 patients were enrolled for this meta-analysis. Analysis results suggested that up-regulation of IGF-1R in GC patients was significantly associated with TNM staging (OR=5.20, 95%CI:1.12 to 24.15, P=0.035), lymph node metastasis(OR=8.24, 95%CI:2.68 to 25.34, P=0.000) and distant metastasis(OR=17.34, 95%CI:6.52 to 46.15, P=0.000). Moreover, up-regulated IGF-1R expression was significantly associated with poor overall survival of gastric cancer patients(HR=2.63, 95% CI:1.29 to 5.40, Z=2.64, P=0.008).

CONCLUSIONHigh IGF-1R expression may be an adverse prognostic factor in gastric cancer patients.
