Abstract
Currently, obesity and its complications have become increasingly serious health issues. Bariatric surgery is an effective method of treating obesity and related metabolic complications. Among them, Roux-en-Y gastric bypass (RYGB) is still considered the "gold standard" procedure for bariatric surgery. Small bowel obstruction is one of the possible complications after RYGB, and in addition to the formation of intra-abdominal hernias, kinking of the jejunojejunal anastomosis is an important cause of small bowel obstruction. The early clinical symptoms of kinking of the jejunojejunal anastomosis often lack clarity in the early stages. Therefore, early diagnosis, prevention, and effective treatment of kinking of the jejunojejunal anastomosis are challenging but crucial. The occurrence of kinking of the jejunojejunal anastomosis may be related to surgical techniques and the surgeon's experience. The use of anti-obstruction stitch, mesenteric division, and bidirectional jejunojejunal anastomosis may be beneficial in preventing kinking of the jejunojejunal anastomosis. If kinking of the jejunojejunal anastomosis occurs, timely abdominal CT scans and endoscopic examinations should be performed. Gastric and intestinal decompression should be initiated immediately, and exploratory surgery should be prepared.

Abstract
MnNb2 O6 anode has attracted much attention owing to its unique properties for holding Li ions. Unluckily, its application as a Li-ion battery anode is restricted by low capacity because of the inferior electronic conductivity and limited electron transfer. Previous studies suggest that structure and component optimization could improve its reversible capacity. This improvement is always companied by capacity increments, however, the reasons have rarely been identified. Herein, MnNb2 O6 -C nanofibers (NFs) with MnNb2 O6 nanoparticles (~15 nm) confined in carbon NFs, and the counterpart MnNb2 O6 NFs consisting of larger nanoparticles (40-100 nm) are prepared by electrospinning for clarifying this phenomenon. The electrochemical evaluations indicate that the capacity achieved by the MnNb2 O6 NF electrode presents an activation process and a degradation in subsequence. Meanwhile, the MnNb2 O6 -C NF electrode delivers high reversible capacity and ultra-stable cycling performance. Further analysis based on electrochemical behaviors and microstructure changes reveals that the partial structure rearrangement should be in charge of the capacity increment, mainly including pseudocapacitance increment. This work suggests that diminishing the dimensions of MnNb2 O6 nanoparticles and further confining them in a matrix could increase the pseudocapacitance-dominated capacity, providing a novel way to improve the reversible capacity of MnNb2 O6 and other intercalation reaction anodes.

Abstract
Sodium-ion hybrid capacitors (SIHCs) have attracted extensive interest due to their applications in sodium-ion batteries and capacitors, which have been considered expectable candidates for large-scale energy storage systems. The crucial issues for achieving high-performance SIHCs are the reaction kinetics imbalances between the slow Faradic battery-type anodes and fast non-Faradaic capacitive cathodes. Herein, we propose a simple self-template strategy to prepare kinetically well-matched porous framework dual-carbon electrodes for high-performance SIHCs, which stem from the single precursor, sodium ascorbate. The porous framework carbon (PFC) is obtained by direct calcination of sodium ascorbate followed by a washing process. The sodium-ion half cells with PFC anodes exhibit high reversible capacity and fast electrochemical kinetics for sodium storage. Moreover, the as-obtained PFC can be further converted to porous framework activated carbon (PFAC) with rich porosity and a high specific surface area, which displays high capacitive properties. By using kinetically well-matched battery-type PFC anodes and capacitive PFAC cathodes, dual-carbon SIHCs are successfully assembled, which can work well in 0-4 V. The optimal PFC//PFAC SIHC exhibits high energy density (101.6 Wh kg-1 at 200 W kg-1), power density (20 kW kg-1 at 51.1 Wh kg-1), and cyclic performance (71.8 % capacitance attenuation over 10,000 cycles).

Abstract
Gastroesophageal reflux disease (GERD) is a common digestive tract disease. Obesity is an independent risk factor for GERD. Laparoscopic sleeve gastrectomy (laparoscopic sleeve gastrectomy, LSG) is becoming more popular in bariatric metabolic surgery and is simple to perform with fewer complications, but its efficacy in treating postoperative anti-reflux in obese patients remains controversial. LSG has been reported to disrupt anti-reflux barrier function, such as altered cardiac notch, disruption of diaphragmatic continuity, and increased hiatal hernia after surgery. The cardiac notch is one of the important anti-reflux barriers at the gastroesophageal junction, and its accentuation has been shown to be effective in alleviating the symptoms of GERD, and LSG combined with angle of cardiac notch accentuation is expected to be an effective measure to prevent GERD after obesity surgery. Therefore, this article mainly reviews the research on the prevention of GERD by bariatric surgery, aiming to explore the effective treatment of GERD in obese patients after surgery, so as to improve the symptoms and quality of life of patients with GERD, and provide reference for the surgical treatment of GERD.

Abstract
Objective: To compare the long-term outcomes of intersphincteric (trans-internal and external) sphincter resection (ISR) and abdominoperineal proctocolectomy (APR) for low-grade rectal cancer. Methods: We used a meta-analytic approach to compare these procedures . Published reports comparing ISR and APR for low rectal cancer in Pubmed, Medline, EMBASE and Cochrane, China Knowledge Network (CNKI), China Biomedical Literature Database, and Vipers databases between January 2005 and January 2023 were searched and those meeting the eligibility criteria were selected for extraction of data for analysis. Inclusion criteria were as follows: (1) all reports comparing ISR and APR for low rectal cancer before January 2023; and (2) prospective randomized controlled studies or well-designed cohort studies. Exclusion criteria were as follows: (1) full text not available; (2) duplicate publications, missing primary outcome indicators, and unknown data; and (3) invalid statistical analysis. Results: Sixteen studies with 2498 patients were included in this study. Compared with the APR group, patients in the ISR group were relatively younger (weighted mean difference [WMD]=-1.82, 95%CI=-2.94 to -0.70, P=0.01), had tumors farther from the anal verge (WMD=0.43, 95%CI=0.18 to 0.67, P<0.01), and lower pathological T-stage (T3-4 stage: OR=0.54, 95%CI=0.36 to 0.81, P<0.01). In contrast, there were no statistically significant differences between the two groups in gender (P=0.78), body mass index (P=0.77), or pathological N stage (P=0.09). Compared with the APR group, patients in the ISR group had a lower rate of postoperative complications (OR=0.77, 95%CI=0.60 to 0.99, P=0.04), shorter hospital stay (WMD=-4.30, 95%CI=-7.07 to -1.53, P<0.01), higher 5-year overall survival (HR=0.54, 95%CI=0.33 to 0.88, P=0.01), and higher 5-year disease-free survival (HR=0.65, 95%CI=0.47 to 0.90, P<0.01). Five-year locoregional failure (HR=0.66, 95%CI=0.40 to 1.10, P=0.11) and time to surgery (WMD=-9.71, 95%CI=-41.89 to 22.47, P=0.55) did not differ significantly between the two groups. Conclusion: ISR is a safe and effective alternative to APR for early-stage low-grade rectal cancer.

Abstract
Obstructive colorectal cancer is a common malignant bowel obstruction. Colostomy or colostomy following tumor resection may be the first choice for emergency surgery. The intestinal and systemic conditions of patients undergoing emergency surgery are often poor, and patients need to undergo multiple operations, which increase the surgical risk and economic burden and reduce the quality of life of patients. Poor intraoperative visualization may also affect the radical operation of emergency surgery. Transanal decompression tube (TDT) can rapidly decompress and drain the obstructed bowel, effectively relieve obstruction symptoms, and improve the success rate of primary radical resection. The TDT squeeze the tumor lightly, causing no spread of tumor cells, and is cheap, but the cavity of transanal decompression tube is small and easily blocked, and requires tedious flushing or regular replacement. Self-expanding metallic stents (SEMS) can relieve intestinal obstruction effectively, provide sufficient preparation time for preoperative examination and improvement of nutritional status. By improving patient's tolerance to radical surgery, SEMS might be used as an important treatment strategy choice for obstructive colorectal cancer. However, SEMS may squeeze the tumor, leading to the spread of tumor cells, increase the recurrence rate and metastasis rate, and reduce the survival rate. Moreover, intestinal wall edema still existed during the operation following SEMS, and the rate of ostomy after anastomosis was as high as 34%. We hypothesized that prolonging the interval between stent insertion and surgery to 2 months, with neoadjuvant chemotherapy administered during this interval (SEMS-neoadjuvant chemotherapy strategy), would help improve outcomes. The SEMS-neoadjuvant chemotherapy strategy is a safe, effective, and well tolerated treatment approach with a high laparoscopic resection rate, low stoma formation rate and improvement in the overall survival for patients with left-sided colon cancer obstruction. The patient physical status is improved, the primary tumor is downstaged, and intestinal wall edema is relieved during the relatively longer interval between SEMS placement and surgery. The SEMS-neoadjuvant chemotherapy strategy may be a preferred therapeutic strategy for obstructive left colon cancer.

Abstract
Objective: To compare the effects of three treatment options: emergency surgery, stent-surgery, and stent-neoadjuvant chemotherapy-surgery, on the pathological characteris- tics of surgically-resected specimens from patients with completely obstructive colorectal cancer. Methods: This was a retrospective cohort study analyzing clinicopathological data of patients with complete obstructive colorectal cancer who were admitted to the General Surgery Department of Beijing Chaoyang Hospital, Capital Medical University, between May 2012 and August 2020. The inclusion criteria were diagnosed with complete colorectal obstruction, pathologically confirmed as adenocarcinoma, resectable on imaging assessment, and without distant metastasis, combined with the patients' clinical manifestations and imaging examination findings. Patients with multiple colorectal cancers, refusal to undergo surgery, and concurrent peritonitis or intestinal perforation before stenting of the intestinal obstruction were excluded. Eighty-nine patients with completely obstructive colorectal cancer were enrolled in the study and were divided into emergency surgery group (n=30), stent-surgery group (n=34), and stent-neoadjuvant chemotherapy- surgery group (n=25) according to the treatment strategy. Differences in the pathological features (namely perineural infiltration, lymphovascular infiltration, tumor deposits, specimen intravascular necrosis, inflammatory infiltration, abscesses, mucus lake formation, foreign body giant cells, calcification, and tumor cell ratio) and biomolecular markers (namely cluster of differentiation (CD)34, Ki67, Bcl-2, matrix metalloproteinase-9, and hypoxia-inducible factor alpha) were recorded. Pathological evaluation was based on the presence or absence of qualitative evaluation of pathological features, such as peripheral nerve infiltration, vascular infiltration, and cancer nodules within the specimens. The evaluation criteria for the pathological features of the specimens were as follows: Semi-quantitative graded evaluation based on the proportion of tissue necrosis, inflammatory infiltrates, abscesses, mucus lake formation, foreign body giant cells, calcification, and tumor cells in the field of view within the specimen were classified as: grade 0: not seen within the specimen; grade 1: 0-25%; grade 2: 25%-50%; grade 3: 50%-75%; and grade 4: 75%-100%. The intensity of cellular immunity was classified as none (0 points), weak (1 point), moderate (2 points), and strong (3 points). The two evaluation scores were then multiplied to obtain a total score of 0-12. The immunohistochemical results were also evaluated comprehensively, and the results were defined as: negative (grade 0): 0 points; weakly positive (grade 1): 1-3 points; moderately positive (grade 2): 4-6 points; strongly positive (grade 3): 7-9 points; and very strong positive (grade 4): 10-12 points. Normally-distributed values were expressed as mean±standard deviation, and one-way analysis of variance was used to analyze the differences between the groups. Non-normally-distributed values were expressed as median (interquartile range: Q1, Q3). A nonparametric test (Kruskal-Wallis H test) was used for comparisons between groups. Results: The differences were not statistically significant when comparing the baseline data for age, gender, tumor site, American Society of Anesthesiologists score, tumor T-stage, N-stage, and degree of differentiation among the three groups (all P>0.05). The differences were not statistically significant when comparing the pathological characteristics of the resected tumor specimens, such as foreign body giant cells, inflammatory infiltration, and mucus lake formation among the three groups (all P>0.05). The rates of vascular infiltration were 56.6% (17/30), 41.2% (15/34), and 20.0% (5/25) in the emergency surgery, stent-surgery, and stent- neoadjuvant chemotherapy-surgery groups, respectively, with statistically significant differences between the groups (χ2=7.142, P=0.028). Additionally, the rate of vascular infiltration was significantly lower in the stent-neoadjuvant chemotherapy-surgery group than that in the emergency surgery group (P=0.038). Peripheral nerve infiltration rates were 55.3% (16/30), 41.2% (14/34), and 16.0% (4/25), in the emergency surgery, stent-surgery, and stent-neoadjuvant chemotherapy-surgery groups, respectively, with statistically significant differences (χ2=7.735, P=0.021). The infiltration peripheral nerve rates in the stent-neoadjuvant chemotherapy-surgery group were significantly lower than those in the emergency surgery group (P=0.032). The necrosis grade was 2 (1, 2), 2 (1, 3), and 2 (2, 3) in the emergency surgery, stent- surgery, and stent-neoadjuvant chemotherapy-surgery groups, respectively, with statistically significant differences (H=10.090, P=0.006). Post hoc comparison revealed that the necrosis grade was higher in the stent-surgery and stent-neoadjuvant chemotherapy-surgery groups compared with the emergency surgery group (both P<0.05). The abscess grade was 2 (1, 2), 3 (1, 3), and 2 (2, 3) in the emergency surgery, stent-surgery, and stent-neoadjuvant chemotherapy-surgery groups, respectively, with statistically significant differences (H=6.584, P=0.037). Post hoc comparison revealed that the abscess grade in the emergency surgery group was significantly lower than that in the stent-surgery group (P=0.037). The fibrosis grade was 2 (1, 3), 3 (2, 3), and 3 (2, 3), in the emergency surgery, stent-surgery, and stent-neoadjuvant chemotherapy-surgery groups, respectively, with statistically significant differences (H=11.078, P=0.004). Post hoc analysis revealed that the fibrosis degree was higher in both the stent-surgery group and the stent- neoadjuvant chemotherapy-surgery group compared with the emergency surgery group (both, P<0.05). The tumor cell ratio grades were 4 (3, 4), 4 (3, 4), and 3 (2, 4), in the emergency surgery, stent-surgery, and stent-neoadjuvant chemotherapy-surgery groups, respectively, with statistically significant differences (H=8.594, P=0.014). Post hoc analysis showed that the tumor cell ratio in the stent-neoadjuvant chemotherapy-surgery group was significantly lower than that in the emergency surgery group (P=0.012). The CD34 grades were 2 (2, 3), 3 (2, 4), and 3 (2, 3) in the emergency surgery, stent-surgery, and stent-neoadjuvant chemotherapy-surgery groups, respectively, and the difference was statistically significant (H=9.786, P=0.007). Post hoc analysis showed that the CD34 grades in the emergency surgery, stent-surgery, and stent-neoadjuvant chemotherapy-surgery groups were 2 (2, 3), 3 (2, 4), and 3 (2,3), respectively. Post hoc analysis revealed that the CD34 concentration was higher in the stent-surgery group than that in the emergency surgery group (P=0.005). Conclusion: Stenting may increase the risk of distant metastases in obstructive colorectal cancer. The stent-neoadjuvant chemotherapy-surgery treatment model promotes tumor cell necrosis and fibrosis and reduces the proportion of tumor cells, vascular infiltration, and peripheral nerve infiltration, which may help decrease local tumor infiltration and distant metastasis in completely obstructive colorectal cancer after stent placement.

Abstract
Objective: To analyze the proportion and clinical characteristics of underdiagnosed zonulopathy in angle closure glaucoma (ACG) patients and to explore the related risk factors. Methods: Case-control study. Continuous cases of ACG patients who underwent phacoemulsification combined with intraocular lens implantation and goniosynechialysis surgery [ACG group, including acute angle closure glaucoma (AACG) and chronic angle closure glaucoma (CACG)] from November 1, 2020 to October 31, 2021 and age-related cataract patients who underwent phacoemulsification combined with intraocular lens implantation surgery in the same period (control group) were included. The diagnosis of zonulopathy was determined according to the intraoperative signs such as wrinkles of the anterior capsule during continuous circular capsulorhexis. The proportion of zonulopathy, preoperative diagnosis rate of zonulopathy, demographic characteristics, anterior chamber depth (ACD), axis length, difference of ACD in both eyes (ACD of the contralateral eye minus ACD of the operated eye) were compared between the two groups. The related risk factors were explored. The paired t-test (comparison between two groups of normally distributed data), non-parametric test (comparison between two groups of non-normally distributed data), Chi-square test (categorical variables), univariate and multivariate logistic regression analysis were used. Results: There were 104 ACG patients (104 eyes), including 63 AACG patients (63 eyes) and 41 CACG patients (41 eyes), and 117 controls (117 eyes). There was no significant difference in age (P=0.29) and gender (P=0.07) between the two groups. The ACG group had shallower anterior chamber (P<0.001), shorter axial length (P<0.001) and more ACD difference in both eyes (P<0.001). In the ACG group, the proportion of zonulopathy was 46.2% (48/104), which was significantly higher than that (6.0%, 7/117) in the control group (P<0.001). In the control group, only zonular laxity was found, while in the ACG group, besides the predominant zonular laxity (68.8%, 33/48), there was zonular dehiscence (31.3%, 15/48). The eyes with AACG (57.1%, 36/63) had a higher proportion of zonulopathy than those with CACG (29.3%, 12/41) (P=0.006). In the ACG group, only 14 cases (29.8%) were diagnosed preoperatively according to slit lamp examination and/or ultrasound biomicroscopy. The proportion of underdiagnosed zonulopathy was 70.8% in the ACG group (34/48). A smaller ACD was found to be related to the zonulopathy in the ACG group. All AACG cases with an ACD ≤2.0 mm and CACG cases with an ACD ≤1.9 mm had zonulopathy. Multivariate logistic regression showed that the ACD difference in both eyes (P=0.025) and the diagnosis of ACG (AACG vs. cataract, P<0.001; CACG vs. cataract, P=0.023) were independent risk factors associated with zonulopathy. Conclusions: The proportion of underdiagnosed zonulopathy among ACG patients is high. Better preoperative diagnostic methods for zonulopathy are needed. Zonulopathy is common in ACG patients, especially in AACG patients, suggesting that zonulopathy may be related to the pathogenesis of ACG. The shallower the ACD, the riskier the zonulopathy. ACD differences between two eyes and ACG types (including AACG and CACG) were related risk factors of zonulopathy.(This article was published ahead of print on the Online-First Publishing Platform for Excellent Scientific Researches of Chinese Medical Association Publishing House on March 11, 2022).

Abstract
Background and purpose The relevance of metastasis-directed stereotactic body radiation therapy (SBRT) remains to be demonstrated through phase III trials. Multiple SBRT procedures have been published potentially resulting in a disparity of practices. Therefore, the french society of urological radiation oncolgists (GETUG) recognized the need for joint expert consensus guidelines for metastasis-directed SBRT in order to standardize practice in trials carried out by the group. Materials and methods After a comprehensive literature review, 97 recommendation statements were created regarding planning and delivery of spine bone (SBM) and non-spine bone metastases (NSBM) SBRT. These statements were then submitted to a national online two-round modified Delphi survey among main GETUG investigators. Consensus was achieved if a statement received ≥ 75 % agreements, a trend to consensus being defined as 65-74 % agreements. Any statement without consensus at round one was re-submitted in round two. Results Twenty-one out of 29 (72.4%) surveyed experts responded to both rounds. Seventy-five statements achieved consensus at round one leaving 22 statements needing a revote of which 16 achieved consensus and 5 a trend to consensus. The final rate of consensus was 91/97 (93.8%). Statements with no consensus concerned patient selection (3/19), dose and fractionation (1/11), prescription and dose objectives (1/9) and organs at risk delineation (1/15). The voting resulted in the writing of step-by-step consensus guidelines. Conclusion Consensus guidelines for SBM and NSBM SBRT were agreed upon using a validated modified Delphi approach. These guidelines will be used as per-protocole recommendations in ongoing and further GETUG clinical trials.

Abstract
Objective: To analyze the short-term efficacy of sleeve gastrectomy plus uncut jejunojejunostomy (SG+uncut JJB) for patients with obesity. Methods: This prospective study was conducted in the General Surgery Department of Beijing Chaoyang Hospital from January to December 2020 (NCT04534504). The inclusion criteria were patients with a body mass index (BMI) of >32.5 kg/m2, type 2 diabetes mellitus (T2DM) or at least two comorbidities with a BMI of 27.5-32.5 kg/m2, a waist circumference of >90 cm (male) or >85 cm (female), and those aged between 16 and 65 years. The exclusion criteria included patients who were pregnant, diagnosed with severe neurological or mental illnesses, long-term users of antidepressants and immunosuppressants, and diagnosed with severe gastroesophageal reflux disease or underwent revision surgery. Patients with incomplete follow-up data or insufficient follow-up time were also excluded. Patients were divided into SG-uncut JJB group and SG group according to doctor's recommendation and patients' wills. The primary endpoint was the percentage of excess weight loss (%EWL), and the secondary endpoints were the percentage of total weight loss (%TWL) and the T2DM remission rate. All patients were regularly followed up until the end of December 2020. Results: After excluding seven patients who did not meet the inclusion criteria, 47 eligible patients were finally identified, with 21 in the SG+uncut JJB group and 26 in the SG group. The operation time (140 [110-180] minutes vs. 90 [70-180] minutes, Z=-3.642, P=0.001) and total cost ([54,000 ± 6000] yuan vs. [49,000 ± 7000] yuan, t=2.590, P=0.013) were slightly higher in the SG+uncut JJB group than in the SG group (all P<0.05). However, no significant differences were observed in terms of postoperative hospital stay, operative blood loss, and postoperative complications between the two groups (all P>0.05). The incidence of nausea and vomiting was significantly lower in the SG+uncut JJB group than in the SG group (9.5% [2/21] vs. 46.2% [12/26], χ2=7.453, P=0.006}. The %EWL and %TWL in the SG+uncut JJB group tended to increase gradually with time. The same trend was also observed in the SG group during the first 6 months of follow-up. The 12-month %EWL and %TWL in the SG group were slightly lower compared with the 6-month %EWL and %TWL (P=0.001). The 12-month %EWL values in the SG+uncut JJB and SG groups were (72.4%±12.3%) and (63.6%±25.7%), respectively. However, no significant differences were observed between the two groups in terms of %EWL. Moreover, the 1-month ([11.1%±2.4%] vs. [8.2%±4.4%], P=0.011) and 12-month %TWL ([29.7%±6.9%] vs. [20.3%±7.2%], P=0.001) were significantly higher in the SG+uncut JJB group than in the SG group. No significant differences were observed in terms of T2DM and hypertension remission (all P>0.05). Conclusion: SG+uncut JJB might achieve a promising weight-loss effect similar to SG with a relatively lower incidence of postoperative nausea and vomiting, and it might be an effective and safe approach for obesity management.

Abstract
Abstract
Background
Pulmonary vein isolation (PVI) is the cornerstone of atrial fibrillation (AF) ablation. Data regarding additional substrate modification has been conflicting, both in paroxysmal and persistent atrial fibrillation.
Purpose
To assess the effect of additional linear substrate modification during de novo AF ablation on AF recurrence.
Methods
We reviewed 1575 AF ablations in 1254 patients from January 2013 to June 2021 at a single academic medical center. There were 1096 de novo ablations. We defined substrate modification as linear ablations including cavotricuspid isthmus (CTI), superior vena cava isolation, intercaval line, mitral isthmus, and left atrial roof and floor lines. We evaluated clinical and procedural characteristics to identify risk factors for AF recurrence and complications. Patients were followed for a minimum of 6 months.
Results
The 1096 de novo ablations included 65.5% males with mean age 61.1 years, mean BMI 31.3, 81.8% paroxysmal AF and 18.2% persistent AF. There were four AF ablation subgroups: PVI alone (41.6%), PVI and CTI ablation (37.1%), PVI with CTI and additional substrate modification (15.6%), and PVI with substrate modification without CTI ablation (5.7%). Overall, AF recurred in 36.9% cases. AF recurrence with PVI only ablation was 41% compared to 32.7% in patients with PVI and CTI ablation (p=0.02). When looking at patients with paroxysmal and persistent AF, results were similar, with decreased AF recurrence with the addition of CTI ablation in both paroxysmal (37.3% v. 29.2%, p=0.03) and persistent AF (58.1% v. 40.0%, p=0.02). Additional substrate modification did not result in significant difference in outcome in either paroxysmal or persistent AF (Figure 1).
Conclusions
In de novo AF ablations, addition of CTI ablation to de novo PVI ablation is associated with lower AF recurrence in both paroxysmal and persistent AF. Additional linear substrate modification did not impact outcomes.

Abstract
Abstract
Background
Atrial fibrillation (AF) ablation is an outpatient procedure with traditionally an overnight hospital observation (OHO). Recently, there has been a trend towards same day discharge (SDD).
Purpose
Compare AF ablation procedure safety outcomes with SDD vs. OHO.
Methods
We reviewed consecutive AF procedures performed from January 2013 to June 2021 at a single academic center. Patients underwent OHO until June 2020, after which patients had SDD whenever feasible. Adverse events were assessed at three months, which included pericardial effusion, pericarditis, post-procedure hypotension, embolic events, and vascular complications. We also assessed emergency department (ED) visits and procedure-related hospital admissions.
Results
There were 1254 patients who underwent 1575 AF ablations. 1440 patients underwent OHO and 135 had SDD. Mean age was 62.2 years, BMI 33 kg/m2, 65% were male, and 27.6% had persistent AF, without significant differences in baseline characteristics between OHO and SDD. We found that SDD was not associated with increased complications (OHO 0.20% v. SDD 0.49%; p>0.05), ED visits, or hospital admissions (2% v. 5%; p>0.05) (Figure 1, 2). There were no gender or age-related disparities in all outcomes (p>0.05).
Conclusion
SDD protocol after AF ablation is feasible and not associated with higher incidence of complications, ED visits, and procedure-related hospitalizations.

Abstract
Abstract
Background
There are conflicting reports in the literature regarding whether body-mass index (BMI) influences the success and procedural complication rates of atrial fibrillation (AF) ablation.
Purpose
To determine if differences in BMI affect AF ablation outcomes
Methods
At a single academic center, AF ablation procedures were reviewed from 2013 to 2021. Primary outcomes were AF recurrence (after a 90 day blanking period), procedure-related complications, emergency department visits or hospital admission (ED/HOSP). Patients had a minimum of 6 months follow-up
Results
We analyzed 1569 AF ablation consecutive procedures (1093 de novo, 476 repeat ablation) using either radiofrequency or cryoablation. The study population was 65% male with a mean age 62 years, with 28% persistent AF. BMI was separated into three cohorts: <25 kg/m2 (N=218), 25–30 kg/m2 (N=547), and >30 kg/m2 (N=804). There were no significant differences in the type of AF, left atrial diameter, or left ventricular ejection fraction in the BMI subgroups. There was a direct relationship between the prevalence of co-morbid conditions and increasing BMI: hypertension (49.1%, 59.9%, 60.2%; p 0.04), diabetes (6.4%, 13.5%, 21.3%; p 0.01), and obstructive sleep apnea (5.5%, 10.8%, 26.7%; p<0.01). There were no significant differences in AF recurrence, procedural complications or ED/HOSP among the BMI cohorts (p>0.05) (Figure 1). No gender related disparities were noted in outcomes (p>0.05).
Conclusion
Higher BMI was not associated with AF recurrence, complications, or ED/HOSP after AF ablation despite a higher prevalence of comorbid medical conditions

Abstract
Fluorescent silicon nanoparticles (SiNPs) were synthesized by a one-step, simple, and green method with 3-Aminopropyltriethoxysilane (APTES) and ascorbic acid (AA) as reaction agents. Subsequently, the SiNPs and AgNPs nanocomplex (SiNPs@AgNPs) was constructed as the probe for hydrogen peroxide (H2O2) detection. The fluorescence of SiNPs was quenched due to the surface plasmonic-enhanced energy transfer between SiNPs and AgNPs. Meanwhile, the color tends to be yellow due to the existence of AgNPs. As the AgNPs were etched by H2O2, the fluorescence recovers and color fadings. Based on the well-designed structure, the "off-on" fluorescence sensing and "on-off" color sensing platforms for H2O2 were fabricated. The as-synthesized materials were characterized by Fourier transform infrared (FT-IR) spectroscopy, dynamic light scattering (DLS), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). Fluorescence and UV-vis absorption spectra were used to evaluate the optical performance. The fabricated sensor exhibited a linear range of 1.0-100.0 μM, with a limit of detection of 0.36 μM for the fluorescence sensing of H2O2. Additionally, a linear range of 1.0-50.0 μM and a limit of detection of 0.45 μM were displayed for the detection of H2O2 by colorimetric assay. The feasibility in complex medium of the fabricated fluorescent and colorimetric dual-signal sensor was evaluated by the detection of H2O2 in phosphate buffer saline (PBS) and lake water samples.

Abstract
Layered metal sulfides are considered as promising candidates for potassium ion batteries (KIBs) owing to the unique interlayer passages for ion diffusion. However, the insufficient electronic conductivity, inevitable volume expansion, and sulfur loss hinder the promotion of K-ion storage performance. Herein, few-layered Ti3C2Tx nanosheets were selected as the multi-functional substrate for cooperating few-layered SnS2 nanosheets, constructing SnS2/Ti3C2Tx hetero-structural nanosheets (HNs) with the thickness as thin as about 5 nm. In this configuration, the formed Ti-S bonds provide robust interaction between SnS2 and Ti3C2Tx nanosheets, which hinders the agglomeration of SnS2 and the restack of Ti3C2Tx, endowing the hybrid material with robust nanostructure. Thus, the shortcomings of the SnS2 anode are muchly relieved. In this way, the as-prepared SnS2/Ti3C2Tx HNs electrode delivers reversible capacities of 462.1 mAh g-1 at 0.1 A g-1 and 166.1 mAh g-1 at 2.0 A g-1, respectively, and a capacity of 85.5 mAh g-1 is remained even after 460 cycles at 2.0 A g-1. These results are superior to those of the counterpart electrode, confirming aggressive promotion of K-ion storage performance of SnS2 anode brought by the cooperation of Ti3C2Tx, and presenting a reliable strategy to improve the electrochemical performance of sulfide anodes.

Abstract
Objective: To identify gene variants and investigate clinical features of nonmuscle myosin heavy chain 9-related disease (MYH9-RD). Methods: In this retrospective study, the data of patients with MYH9-RD admitted to Shenzhen Children's Hospital from July 2017 to September 2020 were extracted. The gene variants, clinical features and laboratory tests results were summarized. Results: Among the 6 children, 4 were males and 2 were females, aged 4.0 (0.5-7.6) years. Main clinical manifestations included thrombocytopenia (6 cases), epistaxis (3 cases), petechias (2 cases), traumatic hematoma (1 case), and abnormal liver enzymes (1 case). One patient had no family history, and the other 5 cases were pedigrees. Two pedigrees (2 cases) had long-term microscopic hematuria, one pedigree (2 cases) had history of early cataract, and three pedigrees (5 cases) had chronic mild elevation of liver enzymes. Four MYH9 gene variants were found in 12 patients, including c.2104C>T(p.R702C) in exon 17, c.4270G>A(p.D1424N) in exon 31, c.5521G>A (p.E1841K) in exon 39, and c.5797C>T (p.R1933X) in exon 41. According to the family pedigrees analysis, except for the case of variant in exon 17 which was spontaneous mutation with no family history, the other variants were from their father or mother. The complete blood count results showed a decreased platelet number in these patients, and the counting results of the automated hematology analyzer were significantly lower than that of manual counting method ((33.4±17.2) × 10⁹ vs. (60.4±21.0) × 109/L,t=-5.83, P<0.05). The examination of the peripheral blood smear revealed the presence of thrombocytopenia with giant platelets and granulocyte inclusion bodies. The MYH9 gene variant (R702C) located at the N-terminus head domain of non-muscle myosin heavy chain ⅡA (NMMHC-ⅡA), which has ATPase activity, led to severe reduction of platelet number (<20×109/L) and obscure granulocyte inclusion bodies. However, higher platelet numbers (40×109-80×109/L) and obvious granulocyte inclusion bodies were observed in patients with tail-position mutations at C-terminus. Conclusions: The clinical phenotypes of MYH9-RD were variable. The mutations in certain regions of MYH9 gene were related to platelet count and granulocyte inclusion bodies. MYH9-RD should be considered in individuals with unknown etiology and persistent thrombocytopenia which is non-responsive to conventional treatment, regardless of family history. Complete blood count and blood smear morphology examinations are the first steps to screen and diagnose the disease. The laboratory should pay attention to the morphological review rules and standardized reports.

Abstract
Objective: To investigate the relationship between inflammatory cell infiltration and nerve damage in patients with fungal keratitis at different degrees of severity. Methods: Retrospective study. A total of 44 consecutive patients (44 eyes) with fungal keratitis in Beijing Tongren Hospital Affiliated to Capital Medical University from January 2017 to December 2019 were selected as the patient group, including 30 males and 14 females, with an age of (58.3±11.5) years old. Twenty healthy people (20 eyes) were included as control group. Slit-lamp microscopy was performed to observe the corneal ulcer. According to the diameter of corneal ulcer, patients were divided into mild, moderate and severe groups. With in vivo confocal microscopic ,the images were obtained from the epithelial layer to the endothelial layer in the central cornea and superior, inferior, nasal and temporal peripheral cornea. Parameters of the maximum density of fungal hyphae, the maximum depth of hyphal infiltration, the density, area and length of dendritic cells (DCs), the nerve density, and the number and curvature of nerve trunks were collected. The Kruskal-Wallis test, Wilcoxon test, and Spearman correlation analysis were used for analyses. Results: On confocal microscopy, many uniform, highly reflective, segment-like structures in parallel or staggered rows were detected in the cornea, with a certain degree of physiological curvature and branching. Quantitative analysis of hyphal density found that the median rating of hyphal density was 2.6 (2.0, 3.0), mainly with medium to large amounts of hyphae. Most hyphae were 100-150 μm in depth (18 cases, 40.9%), and the maximum depth of hyphae in 95.5% (42 cases) of patients was within 300 μm. The hyphal invasion depth in the mild group was 89.4 (50.5, 106.8) μm, in the moderate group was 133 (122, 203) μm, and in the severe group was 135 (74, 151) μm. As the severity of the disease increased, the depth of hyphal invasion increased (F=4.248, P=0.001). Compared with the control group, the DC density [166 (81.3, 212.5) vs. 24.0 (20.8, 32.3) cells/μm2], area [441.3 (291.9, 529.5) vs. 63.7 (47.7, 70.3) μm2] and length [68.3 (39.4, 91.0) vs. 9.2 (7.0, 11.3) μm] increased in patients (W=493.5, 500.0, 500.0; P<0.01). The nerve density [5 398.3 (3 202.7, 6 828.3) vs. 19 171.8 (17 558.8, 21 550.4) μm/mm2; t=-14.448, P<0.01] and the length [692.7 (402.0, 925.1) vs.2 138.4 (1 940.4, 2 597.2) μm; t=-11.930, P<0.01] and number [2.9 (2.0,3.0) vs. 6.0 (5.5,7.0); t=-8.282, P<0.01] of nerve trunks in patients decreased. There were strong negative correlations between the nerve density, the number of nerve trunks, and the DC density (r=-0.555, -0.466; P<0.01). Conclusions: The depth of fungal hypha invasion in patients with fungal keratitis is mainly concentrated in the epithelial layer and superficial stroma layer. The density of mature dendritic cells in the lesion area was negatively correlated with the density and number of subbasal nerves. The density of subbasal nerves decreased as the increase of the severity of the lesion. (Chin J Ophthalmol, 2021, 57: 580-588).

Abstract
The selective exposure of high-index facets at the surface of nanocrystals is an important and challenging research topic. Herein, polyhedral bismuth vanadate (BiVO4) crystals predominantly surrounded by {2 1 3} and {1 2 1} high-index facets were fabricated through the engineering of high-index surfaces by fluorinion (F-) mediated hydrothermal process. The as-prepared BiVO4-0.2F (the feeding amount of NaF was 0.2 g) catalyst exhibited high apparent quantum efficiency of 17.7% under 420 nm light irradiation and 9.3 fold enhancement of O2 evolution relative to its low-index counterparts. Moreover, the growth of high-index facets results in significant enhancement of hydroxyl radical (•OH) production, photocatalytic degradation of Rhodamine B (RhB) and photoelectrochemical (PEC) properties by the BiVO4 polyhedron, relative to its low-index counterparts. The enhanced photoreactivity is the result of the synergistic effect of F- on the surface of the BiVO4 crystals and exposed high-index facets. For one thing, F- on the surface of the BiVO4 facilitate the separation and transport of photo-induced charge carriers. For another, the exposed high-index facets on polyhedral BiVO4 provided much more reactive sites for photocatalytic reactions. Hopefully, this F- mediated method will be a useful guideline for designing and synthesizing novel high-index faceted micro-/nanostructures for overcoming the practical energy and environment problems.

Abstract
The sodium dual ion battery (Na-DIB) technology is proposed as highly promising alternative over lithium-ion batteries for the stationary electrochemical energy-storage devices. However, the sluggish reaction kinetics of anode materials seriously impedes their practical implementation. Herein, a Na-DIB based on TiSe2 -graphite is reported. The high diffusion coefficient of Na-ions (3.21×10-11 -1.20×10-9 cm2 s-1 ) and the very low Na-ion diffusion barrier (0.50 eV) lead to very fast electrode kinetics, alike in conventional surface capacitive storage systems. In-situ investigations reveal that the fast Na-ion diffusion involves four insertion stage compositions. A prototype cell shows a reversible capacity of 81.8 mAh g-1 at current density of 100 mA g-1 , excellent stability with 83.52 % capacity retention over 200 cycles and excellent rate performance, suggesting its potential for next-generation large scale high-performance stationary energy storage systems.

Abstract
Objective: To evaluate the clinical effects of orthokeratology lens on children with myopic anisometropia. Methods: Retrospective case series study. The data of 226 myopic anisometropia children, (10.83±1.56)years old, including 95 males and 131 females, fitted with orthokeratology(OK) lens in Beijing Tongren Hospital from June 2017 to June 2019 were collected. According to the lens wearing condition and baseline anisometropia, they were divided into four groups: group A1 with an average age of (10.68±1.66) years (bilateral OK lens wearing with low anisometropia, 1.0 D≤SE difference<2.5 D, 50 males and 61 females), group A2 with an average age of (11.24±1.38) years (bilateral OK lens wearing with moderate and high anisometropia, SE difference≥2.5 D, 10 males and 23 females), group B1 with an average age of (10.79±1.51) years (unilateral OK lens wearing with low anisometropia, 1.0 D≤SE difference<2.5 D, 17 males and 21 females) and group B2 with an average age of (10.97±1.60) years (unilateral OK lens wearing with moderate and high anisometropia, SE difference≥2.5 D, 18 males and 26 females). After wearing OK lens for one year, the changes of axial length(AL) and AL difference were observed and statistically analyzed. Results: (1) AL changes: after wearing OK-lens for one year, AL of each eye increased. In group A1, the AL of the more myopic eyes and the less myopic eyes increased by (0.20±0.21) mm and (0.24±0.22) mm respectively, and the difference was statistically significant (t=-3.208, P=0.002); in group A2, the AL growth of the more myopic eyes and the less myopic eyes were (0.04±0.11) mm and (0.17±0.14) mm, and the difference was statistically significant (t=-5.545, P<0.001). In group B1, the AL elongation of the more myopic eyes and the less myopic eyes were (0.14±0.21) mm and (0.39±0.23) mm, and in group B2, the AL growth of the more myopic eyes and the less myopic eyes were (0.11±0.14) mm and (0.54±0.24) mm, with statistically significant differences(t=-6.533, -11.643; all P<0.001). There was a linear correlation between AL elongation and age of the more myopic eyes and the less myopic eyes in group A1(corrected R2=0.208, 0.237) and group A2 (corrected R2=0.169, 0.360). There was no linear correlation of the more myopic eyes and the less myopic eyes between AL change and age or baseline myopia in group B1 (F=0.514, 1.205;P=0.602, 0.312) and group B2 (F=0.841, 0.056; P=0.439, 0.946). (2)Change of AL difference: after wearing OK lens for one year, the changes of AL difference in groupA1, A2, B1 and B2 were (-0.04±0.14) mm,(-0.13±0.13) mm,(-0.26±0.24) mm and (-0.43±0.25) mm, and the decrease of AL difference in moderate and high anisometropia groups were greater than that in low anisometropia groups (t =-3.211, -3.180; P=0.002, 0.002).There was a linear correlation between the reduction of AL difference and baseline anisometropia in group A1, A2 and B2 (corrected R2=0.099, 0.149, 0.230), and there was no linear relationship between the decrease of AL difference and the baseline anisometropia in group B1 (F=0.014, P=0.908). Conclusions: Orthokeratology could effectively control the progression of myopia and to treat anisometropia. The effect of myopia control was better in the older binocular OK lens wearers, and for the patients with greater baseline anisometropia, the treatment effect of anisometropia was better.

Abstract
PURPOSE The tolerance of the concurrent use of radiotherapy, pertuzumab and trastuzumab is unknown. The purpose of this study was to evaluate the toxicity of this association in patients treated for HER2 positive metastatic and/or locally recurrent unrespectable breast cancer. MATERIAL AND METHODS A retrospective study was performed in our institution for all consecutive patients treated with concurrent irradiation, pertuzumab and trastuzumab. The radiotherapy was performed while pertuzumab and trastuzumab were administrated as a maintenance treatment at the dose of 420mg (total dose) and 6mg/kg respectively every 3 weeks without chemotherapy. Toxicity was assessed according to the National Cancer Institute Common Terminology Criteria for Adverse Events version 4.0. Left ventricular ejection fraction (LVEF) was measured at baseline and then every 3-4 months. RESULTS We studied 77 patients. treated in between 2013 and 2019 with median follow-up of 38 months (range 0-264 months). Median age was 53 years (33-86). There were 50 patients (64.9%) with metastatic and 27 patients (35.1%) with recurrent disease. All patients received docetaxel followed by P-T as first line treatment and they received 34 cycles (10-85) of pertuzumab and trastuzumab. All patients experienced partial or complete response according to RECIST criteria. Irradiation volumes were whole breast (41 patients, 53.2%) and chest wall (29 patients, 37.7%) at a dose of 50Gy with a median duration of 39 days. Radiotherapy of lymph nodes was performed in 53 patients (68.8%) as following: supraclavicular-infraclavicular and axillary lymph nodes in 52 patients (67.5%), and internal mammary nodes in 31 patients (40.3%). For 20 patients. (26.0%) radiotherapy was palliative: bone irradiation (12 patients, 15.6%), whole-brain radiotherapy (2 patients, 2.6%), cerebral metastasis irradiation (6 patients). As early toxicity we observed: radio dermatitis as following: 36 patients (46.8%) presented grade I, 17 patients (22.1%) presented grade II, and 3 patients (3.9%) presented grade III. One patient (1.3%) presented grade II esophagitis. One patient (1.3%) presented asymptomatic decrease of LVEF during treatment and 6 patients (7.7%) presented a decrease of LVEF. There was no radiation-induced pneumonitis. As late toxicity, we observed 1 (1.3%) case of grade I and 1 (1.3%) with grade II telangiectasia. There was 1 case (1.3%) of grade III cardiac toxicity, 8 months after the concurrent treatment. CONCLUSION The concurrent use of radiotherapy, pertuzumab and trastuzumab is feasible with good tolerance. Larger prospective data with longer follow-up is needed to confirm these results.

Abstract
Conversion-alloy sulfide materials for potassium-ion batteries (KIBs) have attracted considerable attention because of their high capacities and suitable working potentials. However, the sluggish kinetics and sulfur loss result in their rapid capacity degeneration as well as inferior rate capability. Herein, a strategy that uses the confinement and catalyzed effect of Nb2 O5 layers to restrict the sulfur species and facilitate them to form sulfides reversibly is proposed. Taking Sb2 S3 anode as an example, Sb2 S3 and Nb2 O5 are dispersed in the core and shell layers of carbon nanofibers (C NFs), respectively, constructing core@shell structure Sb2 S3 -C@Nb2 O5 -C NFs. Benefiting from the bi-functional Nb2 O5 layers, the electrochemical reversibility of Sb2 S3 is stimulated. As a result, the Sb2 S3 -C@Nb2 O5 -C NFs electrode delivers the rapidest K-ion diffusion coefficient, longest cycling stability, and most excellent rate capability among the controlled electrodes (347.5 mAh g-1 is kept at 0.1 A g-1 after 100 cycles, and a negligible capacity degradation (0.03% per cycle) at 2.0 A g-1 for 2200 cycles is delivered). The enhanced K-ion storage properties are also found in SnS2 -C@Nb2 O5 -C NFs electrode. Encouraged by the stimulated reversibility of Sb2 S3 and SnS2 anodes, other sulfides with high electrochemical performance also could be developed for KIBs.

Abstract
Objective: To explore the prevalence and risk factors of common blinding ocular diseases in the population aged 30 years and above in rural areas of Handan City from 2006 to 2012. Methods: A cohort study with 6 830 subjects from rural areas of Handan City, Hebei Province was designed and conducted. The follow-up duration was 6 years, and the prevalence and incidence of common blinding diseases were evaluated. Logistic regression was used to explore the influencing factors of common blinding ocular diseases. Results: In 2006, 6 830 people participated in the baseline survey. There were 3 163 (46.31%) males and 3 667 (53.69%) females. The average age was (52.3±12.2) years (range, 30 to 97 years). There were 3 435 subjects who had common chronic systematic diseases, with a prevalence of 50.29%. In addition, 1 250 people suffered from common blinding ocular diseases, and the prevalence was 18.30%. There were 4 118 subjects without common blinding ocular diseases at baseline who participated in the six-year follow-up, during the 6-year follow-up, 247 participants developed common blinding ocular diseases. 9% (171/1 899) of patients with chronic systematic diseases developed common blinding ocular diseases, while only 3.42% (76/2 219) of normal subjects developed common blinding ocular diseases, with a statistically significant difference (χ(2)=56.504, P<0.001). The incidence of common blinding ocular diseases was age-dependent. Multivariate regression analysis showed that age (OR=1.045, 95%CI: 1.028-1.062, P<0.001), intraoccular pressure (IOP) (OR=1.064, 95% CI: 1.014-1.116, P=0.011) and baseline chronic diseases (OR=1.749, 95% CI: 1.288-2.375, P<0.001) were risk factors for common blinding ocular diseases. Moreover, the contribution of age, IOP and chronic systematic diseases to the model was 0.436, 0.084 and 0.511, respectively. Conclusions: The prevalence of common blinding ocular diseases among people over 30 years old in Handan is relatively high. From 2006 to 2012, about 1.5% patients of chronic systematic diseases developed common blinding ocular diseases each year. Moreover, chronic systematic diseases increase the risk of blinding ocular diseases sharply, and the effect is stronger than age and intraocular pressure.

Abstract
Potassium-ion batteries (KIBs) are promising alternatives to lithium-ion batteries because of the abundance and low cost of K. However, an important challenge faced by KIBs is the search for high-capacity materials that can hold large-diameter K ions. Herein, copper oxide (CuO) nanoplates are synthesized as high-performance anode materials for KIBs. CuO nanoplates with a thickness of ≈20 nm afford a large electrode-electrolyte contact interface and short K+ ion diffusion distance. As a consequence, a reversible capacity of 342.5 mAh g-1 is delivered by the as-prepared CuO nanoplate electrode at 0.2 A g-1 . Even after 100 cycles at a high current density of 1.0 A g-1 , the capacity of the electrode remains over 206 mAh g-1 , which is among the best values for KIB anodes reported in the literature. Moreover, a conversion reaction occurs at the CuO anode. Cu nanoparticles form during the first potassiation process and reoxidize to Cu2 O during the depotassiation process. Thereafter, the conversion reaction proceeds between the as-formed Cu2 O and Cu, yielding a reversible theoretical capacity of 374 mAh g-1 . Considering their low cost, easy preparation, and environmental benignity, CuO nanoplates are promising KIB anode materials.

Abstract
Objective: To assess the utilization of eye care services in the rural area of Handan, China under the New Rural Cooperative Medical Scheme, and to analyze the factors associated with the uptake of these services. Methods: In a cohort population-based study, subjects who joined both the baseline (2006-2007) and follow-up (2012-2013) were included. Information of demographic characteristics, participation in the New Rural Cooperative Medical Insurance and use of eye care services, comprehensive ophthalmic examinations, blood pressure and fasting was collected. The protocol got approved by the ethics committee of Beijing Tongren Hospital, and each subject signed the informed consent. Results: Of 5 193 eligible participants, 549 [10.6%; 95% confidence interval (CI), 9.8%-11.4%] had used eye care services, and the prevalence had no significant difference from baseline surveys (P=0.20). The municipal hospitals undertook 50.1% of eye care services. "No need" (4 422, 95.2%) was the most common reason cited for not using an eye care service; 2 875 (65.0%) of these participants had at least one type of eye diseases, 3 505 (79.3%) had at least one type of ocular complaints. In the multiple binary logistics regression model, participants who were elder [adjusted odds ratio (OR), 1.319; 95%CI, 1.177-1.478], were female (adjusted OR, 1.466; 95%CI, 1.085-1.981), had a diabetes history (adjusted OR, 1.930; 95%CI, 1.381-2.696), had a low income (adjusted OR, 0.826; 95%CI, 0.688-0.922), had ocular complaints (adjusted OR, 3.556; 95%CI, 2.484-5.091), had refractive errors (adjusted OR, 1.256; 95%CI, 1.007-1.567), had visual impairment (adjusted OR, 4.398; 95%CI, 2.667-7.253) or had cataract (adjusted OR, 1.278; 95%CI, 1.013-1.612) were more likely to take an eye care service. Conclusions: Under the New Rural Cooperative Medical Scheme, the prevalence of New Rural Cooperative Medical Insurance was increased significantly, but the rate of eye care use in the rural area was still low. Further efforts towards higher quality medical service in county hospitals and village clinics as well as better education about eye disease among the rural population may raise the eye care use in rural areas.

Abstract
Objective: To investigate the relationship between the spontaneous focal lamina cribrosa (LC) defect and the progression of visual field defect (VFD) in primary open-angle glaucoma (POAG). Methods: Case-control study. The patients who were diagnosed as POAG with at least 5 visual field results had been collected from June 2018 to January 2019 at Beijing Tongren Hospital Affiliated to Capital Medical University. Serial imaging by swept source optical coherence tomography B-Scan of the optic discs were acquired at the end of the follow-up and LC defects status were reviewed. Intraocular pressure, mean defects of visual field, central corneal thickness and axis length were recorded in the follow-up duration. Eyes were classified as having either progressive or nonprogressive VFD, and associating factors were evaluated by χ(2) or Fisher's test, mixed-effect model analysis and multivariate Logistical regression analysis. Results: A total of 32 subjects (64 eyes) were enrolled in the study with mean age of (47±14) years, the group consisted of 17 males and 15 females. Fourty-five eyes showed nonprogressive VFD. LC defects were more common in eyes without (28/45) rather than with progressive VFD (5/19) (χ(2)=6.896, P=0.009). Eyes with nonprogressive VFD showed longer axis length[(26.82±1.34) mm vs. (25.79±1.44) mm; t=6.589, P=0.013] and wider LC defects diameter[211 (165-326) μm vs. 114 (106-156) μm; Z=4.797, P=0.042]. Multivariate Logistic regression analysis revealed that the presence of LC defect was significantly associated with nonprogressive VFD (odds ratio=0.217, P=0.012). There were 7 subjects with asymmetry VFD and the incedence of LC defects without progression (7/7) is higher than fellow eye with progression (1/7, P=0.002). There was only one patient with progressive VFD showed one LC defect with an smaller diameter (169 μm) than that in the contralateral eyes with stable VFD (269 μm). Conclusions: LC defects are more common in eyes with nonprogressive VFD. Spontaneous LC defects are associated with nonprogressive glaucomatous defects and could be a protective factor for POAG.

Abstract
Hepatocellular carcinoma is the most common primary malignancy of the liver. The chemotherapeutic drug cisplatin is widely used for advanced liver cancer. However, the development of cisplatin resistance in cancer cells, which is related to the decreased cellular susceptibility to apoptosis, results in a major limitation of cisplatin-based chemotherapy. Recently, triggering necroptosis has been proposed to be a novel therapeutic strategy to eradicate apoptosis-resistant cancer cells. In this study, we provided evidence that cisplatin could induce cell death in HepG2 cells, but not in the apoptosis-resistant HepG2/DDP cells. Ectopic expression of RIP3 promoted cisplatin-induced HepG2/DDP cells death, HMGB1 and LDH release. Moreover, we demonstrated that this type of cell death was necroptosis and depended on RIP1-RIP3-MLKL signaling pathway because inhibition of MLKL activity by necrosulfonamide (NSA) or knockdown of RIP1 significantly attenuated cisplatin-induced cell death in HepG2/DDP-RIP3 cells. Finally, we found that ectopic expression of RIP3 sensitized HepG2/DDP cancer cells to cisplatin treatment in vivo. The findings offer new insights into the molecular mechanisms underlying cisplatin-induced necroptosis in liver cancer cells and suggest that combination of cisplatin with other drugs which can restore RIP3 expression in cancer cells maybe a better choice for therapy of apoptosis-resistant cancer.

Abstract
INTRODUCTION Bladder exstrophy is a congenital anomaly involving foetal exposure and protrusion of the open bladder through an incomplete lower abdominal wall. Techniques to surgically correct exstrophy after birth have greatly improved, but it still presents a major challenge to achieve continence and a good quality of life for patients and their families as the pathophysiology of bladder dysfunction is unknown. OBJECTIVES A multimodal approach was used to characterise the histological and biomechanical properties of exstrophy detrusor. These were correlated with myocyte responses to agonists and an evaluation of developmental signalling pathways to evaluate the cause of bladder dysfunction in exstrophy. STUDY DESIGN Detrusor muscle specimens were obtained during corrective surgery from four exstrophy groups: neonatal (1-3 days, n = 8), younger children (7 months-5 years, n = 13) and older children (8-14 years, n = 11) undergoing secondary procedures and cloacal exstrophy (16 days-9 years, n = 9); control specimens were obtained from children (3 months-9 years, n = 14) undergoing surgery for other pathologies but with normal bladder function. Five lines of experiments were undertaken: measurement of connective tissue to detrusor muscle ratio, contractile responses to electrical and agonist stimulation; in vitro biomechanical stiffness, intracellular Ca2+ responses to contractile agonists and immunohistochemistry for proteins (MMP-7, cyclinD1, β-catenin and c-myc) involved in fibrosis generation. Exstrophy data were compared with those from the control group. RESULTS Exstrophy tissue demonstrated reduced smooth muscle compared with connective tissue, reduced contractile responses and greater mechanical stiffness. However, intracellular Ca2+ responses to agonists were maintained. These changes were greatest in neonatal and cloacal exstrophy samples and least in those from older paediatric bladders. Immunolabelled MMP-7, β-catenin and c-myc were reduced in exstrophy samples. DISCUSSION These results highlight the reality that newborns with exstrophy have significantly reduced compliance and bladder underactivity, which may persist or return to normal values with surgery and age. The primary cause of underactivity is increased connective tissue in relation to detrusor muscle; however, detrusor myocyte function remains normal. Finally, the increase of the smooth muscle content in the paediatric bladder group indicates a remodelling response of the bladder to surgical correction and time. Excess gestational fibrosis is associated with changed expression of key proteins in the Wnt-signalling pathway, a potential aetiological factor and therapeutic target. CONCLUSION Results point to connective tissue deposition as the primary pathological process that determines bladder function with normal myocyte function. Future research that reduces connective tissue deposition may lead to improvement in outcomes for these children.

Abstract
Objective: To study the effects of ultraviolet light combined with riboflavin treatment (corneal collagen-crosslinking, CXL) on infectious control and stromal reconstruction of bacterial keratitis. Methods: Experimental Study. A Staphylococcus aureus rabbit keratitis model was established by injecting Staphylococcus aureus broth into the shallow stromal layer of the right eye cornea of New Zealand white rabbits. Forty-four rabbits that successfully established the model were randomly divided into four groups: corneal collagen cross-linking (CXL) group, antibiotic group, CXL+ antibiotic group and untreated group, with 11 rabbits in each group. Before the treatment and at 3, 7, 14 and 28 days after treatment, slit lamp corneal examination, AS-OCT and in vivo confocal microscopy (IVCM) were performed. Clinical efficacy of different treatments were evaluated at different time points. Parameters including conjunctival hyperemia, corneal ulcer, infiltration, edema, and neovascular. Histopathological examinations of corneal lesions were performed in order to detect the infiltration, inflammatory cells and repair in corneal tissue. Normal data were compared with paired t-test and non-normal data were compared with paired rank sum test before and after treatment. Kruskal-Wallis rank sum test was used to compare 4 groups of data and the generalized estimation equation is used to compare the repeated measurement data at each time point and the comparison between the groups of the treatment groups. Results: After treatment, different time points and specimens for pathological observation, we obtained the following results:Conjunctival hyperemia: in CXL and CXL+ antibiotic groups after treatment for 3 days from treatment before 3 (2, -4) and 3 (2, -3),The reduction was 2 (1, -3) and 2 (1, -2), the difference was statistically significant (Z=-3.91, -5.50; P<0.008); 14 days, the antibiotic group changed from 3 (3, -4) to 2 (1, -2) after treatment, the difference was statistically significant (Z=-5.11, P<0.008); the untreated group had no statistical significance before and after treatment. After 14 days of treatment, the area of corneal ulcer (0.08±0.11) cm(2), (0.07±0.05) cm(2) in CXL group and CXL+ antibiotic group was significantly lower than that before treatment (0.40±0.18) cm(2), (0.49±0.24) cm(2). The difference was statistically significant. Significance (Z=-3.29, -3.64; P<0.008); after 14 days of treatment, after 14 days of treatment, neovascularization in the CXL and CXL+ antibiotic groups began to resolve, 1 (1, -2) and 1 (0, -2) at 7 days of treatment. decreased to 1 (1, -1) and 0 (0, -1), the difference was statistically significant (Z=4.57, 3.80; P<0.012 5); The degree of corneal edema was significantly reduced in the CXL group and the CXL+ antibiotic group at 14 days after treatment, which was reduced from (650±154) μm and (785±255) μm before the treatment to (432±95) μm and (455±109) μm, the difference was statistically significant (t=4.50, 4.92; P=0.00); The density of corneal stromal cells was also reduced from (446±257)/mm(2), (321±145)/mm(2) to (107±66)/mm(2), (114±94)/mm(2), the difference was statistically significant (t=4.15, 4.76; P<0.05). Histopathological observation under light microscope showed that most of the corneal ulcers healed in the CXL group and the CXL+ antibiotic group at 7 days of treatment. The epithelial cells were clearly visible and misaligned, and a small amount of neutrophils in the stromal layer. The upper epithelial layer was treated for 14 days. The cells are arranged neatly, the structure is clear, and the inflammatory cells are significantly reduced. Conclusion: Ultraviolet light combined with riboflavin corneal collagen cross-linking has a certain therapeutic effect on rabbit bacterial keratitis infection control and ulcer repair, and can be used as an auxiliary treatment for antibiotics.

Abstract
Objective: To study the relationship between genetic typing and the antibiotic susceptibility of staphylococcus aureus (SA) isolated from keratitis or conjunctivitis patients. Methods: Experimental study. Thirty-four (34) strains of Staphylococcus aureus were isolated from 34 cases of keratitis or conjunctivitis. The genomic DNA was extracted and amplified with PCR. With the method of multi locus sequences typing (MLST), gene fragments from 7 house-keeping genes were amplified and the products were sequenced. The results were submitted to the MLST website (www.pubmlst.org). In comparison with the allele of the corresponding gene, the allele spectrums of the strain were obtained with 7 housekeeping genes. At last, the MLST genotypes of the isolated strains were determined. With the START software, the evolutionary tree was established with UPGMA method. With the microdilution method, the MIC(90) of 13 antimicrobial agents was determined. The MIC(90) value of antimicrobial agents among different genotypes of Staphylococcus aureus was comparatively analyzed. Results: Ten (10) genotypes were obtained from 34 strains of Staphylococcus aureus. The dominant types were ST239, ST2592 and ST188. The clustering of genotyping was relatively concentrated, mainly in group Ⅰ (25 strains of SA, 83.3% of the total), and followed by group Ⅱ (5 strains of SA, 16.7%). The conjunctival isolates were distributed in the subgroup A of group Ⅰ. The cornea isolates were concentrated in subgroup B and group Ⅱ. With the exact probability method, the R×C chi square tests were used as statistic analysis method. The difference between the bacterial genotyping of two sources was statistically significant (P=0.011). Twenty-four strains of SA in group Ⅰ was sensitive to Vancomycin, Rifampicin and Amikacin (sensitivity ratio was 24/24, 20/24 and 20/24, respectively), and was generally resistant to other antibiotics. The values of MIC(90) of ciprofloxacin, ofloxacin, gatifloxacin and moxifloxacin to Staphylococcus aureus in subgroup A (0.16±0.07, 0.51±0.42, 0.31±0.14, 0.22±0.33) were significantly lower than the values in subgroup B(0.74±0.11, 0.84±0.45, 0.67±0.03, 0.68±0.26). The difference was statistically significant (P=0.004, 0.026, 0.034, 0.001). There was no significant difference between the MIC(90) values of the other 9 kinds of antibiotics in the subgroup A and in the subgroup B of Staphylococcus aureus (P value 0.047-0.561). Conclusion: The genotype of Staphylococcus aureus of corneal isolations and conjunctival isolations were different. The conjunctival isolates were distributed in the subgroup A of group Ⅰ and the corneal isolates were concentrated in subgroup B and group Ⅱ. There is a significant correlation between the MLST genotypes and antibiotic sensitivity. (Chin J Ophthalmol, 2018, 54:767-774).

Abstract
Ureteric herniation into the inguinal canal is a rare condition in adults and even more so in the paediatric population. These hernia types can be categorised as paraperitoneal or extraperitoneal. The former are the only varieties encountered in the paediatric literature, where patients are generally infants, while the latter phenomenon is seen in 20% of ureteric herniations in adults. We present a case of an extraperitoneal ureteric herniation into the inguinal canal in a 12-year-old boy with previous surgery for cloacal exstrophy, analyse the existing literature on the condition and make the speculation that the extraperitoneal variety is an adult variant seen in this child because of weakness in the surrounding structures as a result of previous surgery.

Abstract
Objective: To study the histopathology manifestation and imaging characteristics of in vivo confocal microscopy (IVCM) for diagnosis of ocular surface squamous neoplasia (OSSN) and analyze the reliability of IVCM in differential diagnosis from OSSN cases. Methods: A prospective study. Twenty-three patients (23 eyes) with OSSN were collected from September 2015 to November 2017 in Beijing Tongren Eye center. They were underwent the examinations sequentially as follows: visual examination; slit-lamp microscope examination and ocular surface photography; color fundus image; anterior segment optical coherence tomography examination; IVCM examination and histopathology examination after surgery. With histopathology diagnosis, all subjects were divided into two groups: conjunctival intraepithelial neoplasm (CIN) and squamous cell carcinoma (SCC). Compared with histopathological findings, the IVCM results (cell morphology, cytoplasm and nucleus) of OSSN were analyzed. The difference analysis between the count data of two groups was carried out by the chi square test or Fisher's exact test. Receiver operating characteristic curve and area under the curve (AUC) were used to describe the accuracy of each parameter to differentiate SCC from OSSN. Results: There were 12 males and 11 females among the 23 patients aged (62±15) years. With the histopathological diagnosis, there were 15 cases (15 eyes) in the CIN group and 8 cases (8 eyes) in the SCC group. Eye redness, pain, foreign body sensation and tears were the symptoms of OSSN. There was no significant difference in clinical symptoms between the CIN and SCC groups. The size of tumors and the incidence of trophoblastic vessels in the SCC group were greater than those in the CIN group [8.5(6.5-15.5) mm vs. 5.8(4.0-8.5)mm, Z=4.702,P=0.029; 7/8 vs. 5/15, χ2=6.135, P=0.013). In histopathology, multilayered epithelia with cellular polymorphism, varied cytoplasm staining, and slightly thicker nuclei were observed in the CIN group. The corneal epithelial cells of SCC patients were markedly heterogeneous, and the intercellular bridge structure can be detected. Proliferative cells appeared with spindle shaped cells, nuclear mitotic figures and syncytial cells in the SCC group. The IVCM examination in the CIN group and SCC group showed that the cytoplasm was high and the ratio of nuclear plasma increased. There was no significant difference between the two groups in the size of epithelial cells, cytoplasm reflectivity, and nuclear cytoplasm ratio (P=0.053, 0.108, 0.067). The proportions of nuclear mitotic figures, spindle or chimeric cells, nests of whirlpool cells and the abnormal cells of the superficial stroma layer (8/8, 8/8, 8/8 and 8/8) in the SCC group was higher than those (2/15, 1/15, 4/15 and 0/15) in the CIN group, and the difference was statistically significant (P=0.001, 0.001, 0.003; P<0.001). Among these IVCM parameters, the abnormal cells of the superficial stroma layer had the highest diagnostic ability with the AUC value of 1.000, and the following AUC values were 0.933 for mitotic or double nuclei, 0.901 for spindle or chimeric cells, and 0.867 for the nests of whirlpool cells. Conclusions: The IVCM characteristics of OSSN are the dysplastic cells, hyper-reflective cytoplasm and increased nuclear plasma ratio in the corneal epithelium. Dysplastic cells appearing in the superficial stroma layer, nuclear mitotic figures and nests of vortex cells are the main IVCM parameters to support the malignant change of OSSN lesions.

Abstract
Objective: To construct a dynamic enhanced MR based predictive model for early assessing pathological complete response (pCR) to neoadjuvant therapy in breast cancer, and to evaluate the clinical benefit of the model by using decision curve. Methods: From December 2005 to December 2007, 170 patients with breast cancer treated with neoadjuvant therapy were identified and their MR images before neoadjuvant therapy and at the end of the first cycle of neoadjuvant therapy were collected. Logistic regression model was used to detect independent factors for predicting pCR and construct the predictive model accordingly, then receiver operating characteristic (ROC) curve and decision curve were used to evaluate the predictive model. Results: ΔArea(max) and Δslope(max) were independent predictive factors for pCR, OR=0.942 (95%CI: 0.918-0.967) and 0.961 (95%CI: 0.940-0.987), respectively. The area under ROC curve (AUC) for the constructed model was 0.886 (95%CI: 0.820-0.951). Decision curve showed that in the range of the threshold probability above 0.4, the predictive model presented increased net benefit as the threshold probability increased. Conclusions: The constructed predictive model for pCR is of potential clinical value, with an AUC>0.85. Meanwhile, decision curve analysis indicates the constructed predictive model has net benefit from 3 to 8 percent in the likely range of probability threshold from 80% to 90%.

Abstract
Purpose Nuclear factor of activated T cells (NFAT) has been reported to be involved in the development of various types of cancer including adenocarcinoma of the breast. This research was the first to investigate NFAT protein expression in primary non-small cell lung cancer (NSCLC) tissues from Chinese patients. Methods NFAT protein expression was determined in 130 surgically resected primary NSCLC and matched normal tissues by immunohistochemical analysis. The association between NFAT expression and clinical categorical variables was further analyzed with the SPSS software. Results We found that NFAT expression was much higher in 85 tumor tissues (65.4%) and lower in 45 tumor tissues (34.6%) compared with the matched normal tissues. Further statistical analysis by the chi-square test showed that high expression of NFAT proteins was significantly associated with tumor differentiation (p=0.045), invasion (p=0.031), histology (p<0.0001), tumor size (p=0.038) and cigarette smoking history (p=0.024). However, there was no correlation between the expression of NFAT proteins and pTNM classification, and no difference in 5-year survival rate between patients with high or low expression of NFAT proteins. Multivariate logistic regression analysis for the correlation between NFAT protein expression levels and various characteristics showed a significant association with histology (p=0.008, OR=0.273). Conclusion Our results revealed that high NFAT expression was present in Chinese NSCLCs and that NFAT expression might be involved in the process of human lung cancer development.

Abstract
Rational synthesis of flexible electrodes is crucial to rapid growth of functional materials for energy-storage systems. Herein, a controllable fabrication is reported for the self-supported structure of CuCo2 O4 nanodots (≈3 nm) delicately inserted into N-doped carbon nanofibers (named as 3-CCO@C); this composite is first used as binder-free anode for sodium-ion batteries (SIBs). Benefiting from the synergetic effect of ultrasmall CuCo2 O4 nanoparticles and a tailored N-doped carbon matrix, the 3-CCO@C composite exhibits high cycling stability (capacity of 314 mA h g-1 at 1000 mA g-1 after 1000 cycles) and high rate capability (296 mA h g-1 , even at 5000 mA g-1 ). Significantly, the Na storage mechanism is systematically explored, demonstrating that the irreversible reaction of CuCo2 O4 , which decomposes to Cu and Co, happens in the first discharge process, and then a reversible reaction between metallic Cu/Co and CuO/Co3 O4 occurrs during the following cycles. This result is conducive to a mechanistic study of highly promising bimetallic-oxide anodes for rechargeable SIBs.
