BACKGROUND Preoperative evaluation of frailty is limited to a few surgical procedures.However,the evaluation in Chinese elderly gastric cancer(GC)patients remains blank.AIM To validate and estimate the prognostic value of the 11-index modified frailty index(mFI-11)for predicting postoperative anastomotic fistula,intensive care unit(ICU)admission,and long-term survival in elderly patients(over 65 years of age)undergoing radical GC.METHODS This study was a retrospective cohort study which included patients who underwent elective gastrectomy with D2 Lymph node dissection between April 1,2017 and April 1,2019.The primary outcome was 1-year all-cause mortality.The secondary outcomes were admission to ICU,anastomotic fistula,and 6-mo mortality.Patients were divided into two groups according to the optimal grouping cutoff of 0.27 points from previous studies:High risk of frailty marked as mFI-11High and low risk of frailty marked as mFI-11Low.Survival curves between the two groups were compared,and univariate and multivariate regression analyses were performed to explore the relationship between preoperative frailty and postoperative complications in elderly patients undergoing radical GC.The discrimination ability of the mFI-11,prognostic nutritional index,and tumornode-metastasis pathological stage to identify adverse postoperative outcomes was assessed by calculating the area under the receiver operating characteristic(ROC)curve.RESULTS A total of 1003 patients were included,of which 13.86%(139/1003)were defined as having mFI-11High and 86.14%(864/1003)as having mFI-11Low.By comparing the incidence of postoperative complications in the two groups of patients,it was found that mFI-11High patients had higher rates of 1-year postoperative mortality,admission to ICU,anastomotic fistula,and 6-mo mortality than the mFI-11Low group(18.0%vs 8.9%,P=0.001;31.7%vs 14.7%,P<0.001;7.9%vs 2.8%,P<0.001;and 12.2%vs 3.6%,P<0.001).Multivariate analysis revealed mFI-11 as an independent predictive indicator for postoperative outcome[1-y

BACKGROUND Operation is the primary therapeutic option for patients with distal gastrectomy.Braun anastomosis is usually performed after Billroth Ⅱ reconstruction,which is wildly applied on distal gastrectomy because it is believed to benefit patients.However,studies are needed to confirm that.AIM To identify whether the addition of Braun anastomosis to Billroth Ⅱ reconstruction on laparoscopy-assisted distal gastrectomy benefits patients.METHODS A total of 143 patients with gastric cancer underwent laparoscopy-assisted distal gastrectomy at Centre 1 of PLA general hospital between January 2015 and December 2019.Clinical data of the patients were collected,and 93 of the 143 patients were followed up.These 93 patients were divided into two groups:Group 1(Billroth Ⅱ reconstruction,33 patients);and Group 2(Billroth Ⅱ reconstruction combined with Braun anastomosis,60 patients).Postoperative complication follow-up data and relevant clinical data were compared between the two groups.RESULTS There were no significant differences between Group 1 and Group 2 in postoperative complications(6.1%vs 6.7%,P=0.679),anal exhaust time or blood loss.The follow-up prevalence of reflux gastritis indicated no significant difference between Group 1 and Group 2(68.2%vs 51.7%,P=0.109).The followup European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core-30 scores revealed no evident difference between Group 1 and Group 2 as well.Group 1 had a shorter operating time than Group 2 on average(234.6 min vs 262.0 min,P=0.017).CONCLUSION Combined with Billroth Ⅱ reconstruction,Braun anastomosis has been applied due to its ability to reduce the prevalence of reflux gastritis.Whereas in this study,the prevalence of reflux gastritis showed no significant difference,leading to a conclusion that under the circumstance of Braun anastomosis costing more time and more money,simple Billroth Ⅱ reconstruction should be widely applied.

BACKGROUND Three-dimensional(3D) laparoscopic technique has gradually been applied to the treatment of carcinoma in the remnant stomach(CRS), but its clinical efficacy remains controversial.AIM To compare the short-term and long-term results of 3D laparoscopic-assisted gastrectomy(3DLAG) with open gastrectomy(OG) for CRS.METHODS The clinical data of patients diagnosed with CRS and admitted to the First Medical Center of Chinese PLA General Hospital from January 2016 to January 2021 were retrospectively collected. A total of 84 patients who met the inclusion and exclusion criteria were enrolled. All their clinical data were collected and a database was established. All patients were treated with 3DLAG or OG by experienced surgeons and were divided into two groups based on the different surgical methods mentioned above. By using outpatient and telephone follow-up,we were able to determine postoperative survival and tumor status. The postoperative short-term efficacy and 1-year and 3-year overall survival(OS) rates were compared between the two groups.RESULTS Among 84 patients with CRS, 48 were treated with OG and 36 with 3DLAG. All patients successfully completed surgery. There was no significant difference between the two groups in terms of age, gender, body mass index, ASA score,initial disease state(benign or malignant), primary surgical anastomosis method,interval time of carcinogenesis, and tumorigenesis site. Patients in the 3DLAG group experienced less intraoperative blood loss(188.33 ± 191.35 mL vs 305.83 ± 303.66 mL;P =0.045) and smaller incision(10.86 ± 3.18 cm vs 20.06 ± 5.17 cm;P < 0.001) than those in the OG group. 3DLAGC was a more minimally invasive method. 3DLAGC retrieved significantly more lymph nodes than OG(14.0 ± 7.17 vs 10.73 ± 6.82;P = 0.036), whereas the number of positive lymph nodes did not differ between the two groups(1.56 ± 2.84 vs 2.35 ± 5.28;P = 0.413). The complication rate(8.3% vs 20.8%;P = 0.207) and intensive care unit admission rate(5.6% vs 14.5%;P = 0.372) were equivalent betwee

BACKGROUND The studies of laparoscopic-assisted transhiatal gastrectomy(LTG) in patients with Siewert type Ⅱ adenocarcinoma of the esophagogastric junction(AEG) are scarce.AIM To compare the surgical efficiency of LTG with the open transhiatal gastrectomy(OTG) for patients with Siewert type Ⅱ AEG.METHODS We retrospectively evaluated a total of 578 patients with Siewert type Ⅱ AEG who have undergone LTG or OTG at the First Medical Center of the Chinese People’s Liberation Army General Hospital from January 2014 to December 2019. The short-term and long-term outcomes were compared between the LTG(n = 382) and OTG(n = 196) groups.RESULTS Compared with the OTG group, the LTG group had a longer operative time but less blood loss, shorter length of abdominal incision and an increased number of harvested lymph nodes(P < 0.05). Patients in the LTG group were able to eat liquid food, ambulate, expel flatus and discharge sooner than the OTG group(P < 0.05). No significant differences were found in postoperative complications and R0 resection. The 3-year overall survival and disease-free survival performed better in the LTG group compared with that in the OTG group(88.2% vs 79.2%, P = 0.011;79.7% vs 73.0%, P = 0.002, respectively). In the stratified analysis, both overall survival and disease-free survival were better in the LTG group than those in the OTG group for stage Ⅱ/Ⅲ patients(P < 0.05) but not for stage I patients.CONCLUSION For patients with Siewert type Ⅱ AEG, LTG is associated with better short-term outcomes and similar oncology safety. In addition, patients with advanced stage AEG may benefit more from LTG in the long-term outcomes.

BACKGROUND Gastric cancer(GC)is a heavy burden in China.Nutritional support for GC patients is closely related to postoperative rehabilitation.However,the role of early oral feeding after laparoscopic radical total gastrectomy in GC patients is unclear and high-quality research evidence is scarce.AIM To prospectively explore the safety,feasibility and short-term clinical outcomes of early oral feeding after laparoscopic radical total gastrectomy for GC patients.METHODS This study was a prospective cohort study conducted between January 2018 and December 2019 based in a high-volume tertiary hospital in China.A total of 206 patients who underwent laparoscopic radical total gastrectomy for GC were enrolled.Of which,105 patients were given early oral feeding(EOF group)after surgery,and the other 101 patients were given the traditional feeding strategy(control group)after surgery.Perioperative clinical data were recorded and analyzed.The primary endpoints were gastrointestinal function recovery time and postoperative complications,and the secondary endpoints were postoperative nutritional status,length of hospital stay and expenses,etc.RESULTS Compared with the control group,patients in the EOF group had a significantly shorter postoperative first exhaust time(2.48±1.17 d vs 3.37±1.42 d,P=0.001)and first defecation time(3.83±2.41 d vs 5.32±2.70 d,P=0.004).In addition,the EOF group had a significant shorter postoperative hospitalization duration(5.85±1.53 d vs 7.71±1.56 d,P<0.001)and lower postoperative hospitalization expenses(16.60±5.10 K¥vs 21.00±7.50 K¥,P=0.014).On the 5th day after surgery,serum prealbumin level(214.52±22.47 mg/L vs 204.17±20.62 mg/L,P=0.018),serum gastrin level(246.30±57.10 ng/L vs 223.60±55.70 ng/L,P=0.001)and serum motilin level(424.60±68.30 ng/L vs 409.30±61.70 ng/L,P=0.002)were higher in the EOF group.However,there was no significant difference in the incidence of total postoperative complications between the two groups(P=0.507).CONCLUSION Early oral feeding after laparoscopic radical total g

Temozolomide(TMZ)is an anticancer agent used to treat glioblastoma,typically following radiation therapy and/or surgical resection.However,despite its effectiveness,at least 50%of patients do not respond to TMZ,which is associated with repair and/or tolerance of TMZ-induced DNA lesions.Studies have demonstrated that alkyladenine DNA glycosylase(AAG),an enzyme that triggers the base excision repair(BER)pathway by excising TMZ-induced N3-methyladenine(3meA)and N7-methylguanine lesions,is overexpressed in glioblastoma tissues compared to normal tissues.Therefore,it is essential to develop a rapid and efficient screening method for AAG inhibitors to overcome TMZ resistance in glioblastomas.Herein,we report a robust time-resolved photoluminescence platform for identifying AAG inhibitors with improved sensitivity compared to conventional steady-state spectroscopic methods.As a proof-of-concept,this assay was used to screen 1440 food and drug administration-approved drugs against AAG,resulting in the repurposing of sunitinib as a potential AAG inhibitor.Sunitinib restored glioblastoma(GBM)cancer cell sensitivity to TMZ,inhibited GBM cell proliferation and stem cell characteristics,and induced GBM cell cycle arrest.Overall,this strategy offers a new method for the rapid identification of small-molecule inhibitors of BER enzyme activities that can prevent false negatives due to a fluorescent background.

Sodium-ion batteries(SIBs)are required to possess long cycle life when used for large-scale energy storage.The polyanionic Na_(4)MnV(PO_(4))_(3)(NMVP)reveals good cyclic stability due to its unique three-dimensional(3D)frame structure,but it still faces the challenge of interfacial degradation in practical applications.In this work,NASICON-type Na_(1.3)Al_(0.7)Ti_(1.3)(PO_(4))_(3)(NATP)was deposited on the surface of NMVP to promote interface stability by surface modification and gradient doping.As a result,the optimized NMVP@2%NATP released a capacity retention of 44.8%after 1000 cycles at 5 C,much higher than that of the initial NMVP(28.9%).The enhanced electrochemical performance was mainly attributed to NATP coating acting as a fast ion transport carrier and physical barrier,significantly facilitating the Na^(+)diffusion and isolating side reaction at the electrode/electrolyte interface.On the other hand,Ti_(4)^(+)and Al^(3+)cations from the NATP were partially doped inside the NMVP surface to boost the transport of Na^(+),and the perfect lattice matching of NVMP and NATP improved the interface and structural stability accompanying long cycling.This work demonstrated the effectiveness of surface modification with high lattice match material and provided new perspectives for high energy density solid-state SIBs.

作者： Chuxin qi Zhen song Hongye Cheng Lifang Chen Zhiwen qi State Key Laboratory of Chemical Engineering School of Chemical EngineeringEast China University of Science and Technology130 Meilong RoadShanghai200237China

When considering the usage of ionic liquids(ILs)for reactions and separations involving non-polar or weak-polar hydrocarbons,the knowledge of the mutual solubility behaviors of ILs and hydrocarbons is of the utmost importance.In this work,taking four typical C6-hydrocarbons namely benzene,cyclohexene,cyclohexane,and hexane as representatives,the mutual solubility of ILs and non-polar or weak-polar hydrocarbons are systematically studied based on the COSMO-RS model.The reliability of COSMO-RS for these systems is first evaluated by comparing experimental and predicted hydrocarbon-in-IL activity coefficient at infinite dilution and binary/ternary liquid-liquid equilibria of related systems.Then,the mutual solubility of the four hydrocarbons and13,650 ILs(composed by 210 cations and 65 anions)are predicted.The effect of different IL structural characteristics including alkyl chain length,cation family/symmetry/functional group,and anion on the IL-hydrocarbon mutual solubility behaviors are further analyzed by the analyses of interaction energy and screen charge distribution.The mutual solubility databases and the structural effects identified thereon could provide useful guidance for IL selection in related applications.

Sexual systems play important roles in angiosperm evolution and exhibit substantial variations among different floras. Thus, studying their evolution in a whole flora is crucial for understanding the formation and maintenance of plant biodiversity and predicting its responses to environmental change. In this study, we determined the patterns of plant sexual systems and their associations with geographic elements and various life-history traits in dry-hot valley region of southwestern China, an extremely vulnerable ecosystem. Of the 3166 angiosperm species recorded in this area, 74.5% were hermaphroditic,13.5% were monoecious and 12% were dioecious, showing a high incidence of diclinous species. Diclinous species were strongly associated with tropical elements, whereas hermaphroditic species were strongly associated with temperate and cosmopolitan elements. We also found that hermaphroditism was strongly associated with showy floral displays, specialist entomophily, dry fruits and herbaceous plants.Dioecy was strongly associated with inconspicuous, pale-colored flowers, generalist entomophily, fleshy fruits, and woody plants, whereas monoecy was strongly associated with inconspicuous, pale-colored flowers, anemophily, dry fruits, and herbaceous plants. In addition, hermaphroditic species with generalist entomophily tended to flower in the dry season, whereas diclinous species with specialist entomophily tended to flower in the rainy season. However, independent of sexual systems, plants that produce dry fruits tended to flower in the rainy season and set fruits in the dry season, but the opposite pattern was found for fleshy fruit-producing plants. Our results suggest that in the dry-hot valleys, plant sexual systems are associated with geographic elements as well as various life-history traits that are sensitive to environmental change.
