Abstract
Following the 15 January 2022 Hunga Tonga-Hunga Ha'apai eruption, several trace gases measured by the Aura Microwave Limb Sounder (MLS) displayed anomalous stratospheric values. Trajectories and radiance simulations confirm that the H2O, SO2, and HCl enhancements were injected by the eruption. In comparison with those from previous eruptions, the SO2 and HCl mass injections were unexceptional, although they reached higher altitudes. In contrast, the H2O injection was unprecedented in both magnitude (far exceeding any previous values in the 17-year MLS record) and altitude (penetrating into the mesosphere). We estimate the mass of H2O injected into the stratosphere to be 146 ± 5 Tg, or ∼10% of the stratospheric burden. It may take several years for the H2O plume to dissipate. This eruption could impact climate not through surface cooling due to sulfate aerosols, but rather through surface warming due to the radiative forcing from the excess stratospheric H2O.

Abstract
Neutrino charged-current quasielastic-like scattering, a reaction category extensively used in neutrino oscillation measurements, probes nuclear effects that govern neutrino-nucleus interactions. This Letter reports the first measurement of the triple-differential cross section for ν_{μ} quasielastic-like reactions using the hydrocarbon medium of the MINERvA detector exposed to a wideband beam spanning 2≤E_{ν}≤20 GeV. The measurement maps the correlations among transverse and longitudinal muon momenta and summed proton kinetic energies, and compares them to predictions from a state-of-art simulation. Discrepancies are observed that likely reflect shortfalls with modeling of pion and nucleon intranuclear scattering and/or spectator nucleon ejection from struck nuclei. The separate determination of leptonic and hadronic variables can inform experimental approaches to neutrino-energy estimation.

Abstract
Objective: To explore the clinical safety and feasibility of overlapped delta-shaped anastomosis (ODA) in totally laparoscopic right hemicolectomy (TLRHC). Methods: From May 2017 to October 2019, of the 219 patients who underwent TLRHC at the Cancer Hospital, Chinese Academy of Medical Science and Peking Union Medical College, 104 cases underwent ODA (ODA group) and 115 cases underwent conventional extracorporeal anastomosis (control group) were compared the surgical outcomes, postoperative recovery, pathological outcomes and perioperative complications. Results: The length of the skin incision in the ODA group was significantly shorter than that in the control group [(5.6±0.9) cm vs. (7.1±1.7) cm, P<0.05], and the time to first flatus and first defecation after surgery in the ODA group was significantly earlier than that in the control group [(1.7±0.7) days vs. (2.0±0.7) days; (3.2±0.6) days vs. (3.3±0.7) days, P<0.05]. While the anastomosis time, operation time, intraoperative blood loss, the time of first ground activities, the number of bowel movements within 12 days after surgery, postoperative hospital stay, tumor size, the distal and proximal margins, the number of lymph node harvested and postoperative TNM stage in the ODA group did not differ from that of the control group (P>0.05). The postoperative complication rates of patients in the ODA group and the control group were 3.8% (4/104) and 4.3% (5/115), respectively, and the difference was not significant (P>0.05). Conclusion: The application of ODA technology in TLRHC can significantly shorten thelength of skin incisionand the recovery time of bowel function, and can obtain satisfactory short-term efficacy.

Abstract
Background Anchorage control is one of the components in the treatment of extraction cases. However, what determines more or less anchorage loss is still an unanswered question. Aim: The purpose of this study was to investigate the most important factors contributing to the anchorage loss of maxillary first molars in premolar extraction cases. Materials and Methods The study included 726 upper premolar extraction cases, including 214 male patients and 512 female patients, and the mean age was 14.4 ± 4.5 years old (range: 9-45). Factors including physiological characteristics, treatment mechanics, and cephalometric variables were collected and their influences on the angulation changes of maxillary first molars were analyzed. Results The mean angulation change of maxillary first molar after treatment was 2.81°(mesial tipping). The change of UM/PP showed a statistically significant difference in different sex (male 3.84° ± 5.26° vs female 2.38° ± 5.10°), age (adult -0.05° ± 4.73° vs teenager 3.46° ± 5.07°), and molar relationship (Class II 3.28° ± 5.15° vs Class I 2.36° ± 5.19°). There are six variables accounted in the regression analysis (R = 0.608, R2 = 37.0%). Among them, the pre-treatment molar tipping (Standardized Coefficients: -0.65) and the pre-treatment incisor/molar height ratio (Standardized Coefficients: -0.27) were the most important factors influencing anchorage loss during treatment. Conclusion Compared with treatment-related factors, the patient's physiological characteristics play a more important role in anchorage loss. The pre-treatment angulation of the maxillary first molar is the most influential factor in changes to maxillary molar angulation, which are often predisposing anchorage loss.

Abstract
Objective: To investigate the expression of cortactin in colorectal cancer and its correlation with clinicopathological parameters and prognosis. Methods: The expressions of cortactin in normal colorectal mucosal tissue and colorectal cancer tissue in paraffin-embedded tissue microarray from 319 patients who were diagnosed as colorectal cancer and treated in Cancer Hospital of Chinese Academy of Medical Sciences from 2006 to 2009 was detected by immunohistochemistry. Kaplan-Meier method and Log rank test were used for survival analysis, and Cox proportional risk regression model was used for multivariate analysis. Results: The positive expression rates of cortactin in colorectal cancer tissue and normal colorectal mucosal tissue were 61.1% (195/319) and 5.6% (18/319, P<0.001), respectively. T-stage, N-stage, American Joint Committee on Cancer (AJCC) stage, degree of tumor differentiation, neural invasion and preoperative carcinoembryonic antigen (CEA) levels were associated with the expression of cortactin (P<0.05). The positive expression of cortactin was associated with poorer disease-free survival (P=0.036) and overall survival (P=0.043), and the effect was more significant in patients with stage Ⅱ to Ⅲ. For patients with stage Ⅱ-Ⅲ colorectal cancer, postoperative adjuvant therapy was associated with disease-free survival (P=0.007) and overall survival (P=0.015). The vascular tumor embolus, pathological type, preoperative CEA level and cortactin expression were independent influencing factors for disease-free survival (P<0.05). The age, AJCC stage, preoperative CEA level and cortactin expression were independent influencing factors for overall survival (P<0.05). Preoperative CEA level and cortactin expression were independent influencing factors for disease-free survival and overall survival (P<0.05). Conclusion: Cortactin is expressed in colorectal cancer and in stage Ⅱ-Ⅲ patients, it is a potential predictor of colorectal cancer prognosis.

Abstract
The objective of this study was to determine growth, feed intake, and feed efficiency of postbred dairy heifers with different genomic residual feed intake (RFI) predicted as a lactating cow when offered diets differing in energy density. Postbred Holstein heifers (n = 128, ages 14-20 mo) were blocked by initial weight (high, medium-high, medium-low, and low) with 32 heifers per block. Each weight block was sorted by RFI (high or low) to obtain 2 pens of heifers with high and low genomically predicted RFI within each block (8 heifers per pen). Low RFI heifers were expected to have greater feed efficiency than high RFI heifers. Dietary treatments consisted of a higher energy control diet based on corn silage and alfalfa haylage [HE; 62.7% total digestible nutrients, 11.8% crude protein, and 45.6% neutral detergent fiber; dry matter (DM) basis], and a lower energy diet diluted with straw (LE; 57.0% total digestible nutrients, 11.7% crude protein, and 50.1% neutral detergent fiber; DM basis). Each pen within a block was randomly allocated a diet treatment to obtain a 2 × 2 factorial arrangement (2 RFI levels and 2 dietary energy levels). Diets were offered in a 120-d trial. Dry matter intake by heifers was affected by diet (11.0 vs. 10.0 kg/d for HE and LE, respectively) but not by RFI or the interaction of RFI and diet. Daily gain was affected by the interaction of RFI and diet, with low RFI heifers gaining more than high RFI heifers when fed LE (0.94 vs. 0.85 kg/d for low and high RFI, respectively), but no difference for RFI groups when fed HE (1.16 vs. 1.19 kg/d for low and high RFI, respectively). Respective feed efficiencies were improved for low RFI compared with high RFI heifers when fed LE (10.6 vs. 11.8 kg of feed DM/kg of gain), but no effect of RFI was found when fed HE (9.4 vs. 9.5 kg of DM/kg of gain for high and low RFI, respectively). No effect of RFI or diet on first-lactation performance through 150 DIM was observed. Based on these results, the feed efficiency of heifers having different genomic RFI may be dependent on diet energy level, whereby low RFI heifers utilized the LE diet more efficiently. The higher fiber straw (LE) diet controlled intake and maintained more desirable heifer weight gains. This suggests that selection for improved RFI in lactating cows may improve feed efficiency in growing heifers when fed to meet growth goals of 0.9 to 1.0 kg of gain/d.

Abstract
OBJECTIVES The purpose of this study was to investigate the association and mediation pathways among muscle mass, muscle function (muscle strength and physical performance), and malnutrition with depressive symptoms clusters in the older hemodialysis patients. DESIGN A multi-center cross-sectional study. SETTING AND PARTICIPANTS A total of 499 patients aged ≥ 60 on hemodialysis from seven facilities in Shanghai of China from 2020 to 2021. MEASUREMENTS Muscle mass was assessed by skeletal muscle index(SMI). Muscle strength was measured by handgrip strength, and physical performance was measured via gait speed and Timed Up and Go Test (TUGT). Nutritional status was assessed by Malnutrition Inflammation Score (MIS). Depressive symptoms were evaluated by the Patient Health Questionnaire-9 (PHQ-9). Logistic regression and mediation analyses fully adjusted for all potential confounding factors. RESULTS Among 499 participants (312 men, mean age 69.2±6.6 years), 108 (21.6%) had depressive symptoms. The muscle strength, physical performance and malnutrition were associated with depressive symptoms. Furthermore, malnutrition significantly mediated the association of muscle function with total, cognitive-affective symptoms. The association of the muscle function with somatic symptoms were mediated by the nutritional status. The mediated proportions of malnutrition in the relationship between physical performance and depressive symptoms clusters were stronger in somatic symptoms than in cognitive-affective symptoms. CONCLUSIONS Our findings suggest that muscle function rather than muscle mass may contribute substantially to the development of depressive symptoms clusters in the hemodialysis via malnutrition. The malnutrition mediated stronger in the association of muscle function with somatic symptoms. These findings may help guide clinicians to better diagnose and manage depression in the context of concomitant muscle function and malnutrition.

Abstract
Objective: To evaluate the diagnostic performance of the Chinese Ultrasound Thyroid Imaging Reporting and Data System (C-TIRADS) in thyroid nodules,and to compare it with the TIRADS proposed by Kwak et al. (K-TIRADS) and the TIRADS proposed by the American College of Radiology (ACR-TIRADS). Methods: The data of 1 750 patients with 2 029 thyroid nodules in the Department of Thyroid Surgery, the Affiliated Hospital of Jining Medical University from January 2018 to November 2020 was retrospectively collected. Among them, there were 328 males and 1 422 females,aged from 6 to 86 with an average of (47±12) years. The nodules were divided into≤1.0 cm group(n=997) and>1.0 cm group(n=1 032)based on the size of the nodules. The stratification for malignant risk and the determination of benign or malignancy of the nodules was evaluated using the C-TIRADS, K-TIRADS and ACR-TIRADS, respectively. The receiver operating characteristic (ROC)curve analysis was performed to compare the diagnostic performance of the aforementioned three kinds of TIRADS using pathological results as the referent standard. Results: The optimal diagnosis points in the determination of malignant nodules of C-TIRADS, K-TIRADS and ACR-TIRADS in the two groups were 4A, 4b and 4 respectively according to ROC curve analysis. For the diagnosis of the malignant nodules, the C-TIRADS achieved with an AUC value of 0.772 and 0.892 in the ≤1.0 cm group and>1.0 cm group, respectively, which was significantly higher than K-TIRADS (AUC= 0.762 and 0.869, respectively) and ACR-TIRADS (AUC= 0.735 and 0.832, respectively) (P<0.05). The sensitivity, specificity, accuracy, positive predictive value and negative predictive value of C-TIRADS were 94.99%, 59.41%, 86.46%, 88.13%, 78.89% (≤1.0 cm group)and 88.34%, 90.05%, 89.34%, 86.33%, 91.57%(>1.0 cm group), respectively. C-TIRADS had the highest sensitivity, accuracy, and negative predictive value in the determination of malignant nodules in both groups compared to the other two kinds of TIRADS. Conclusions: The three kinds of TIRADS all have high diagnostic performance for the determination of the malignant nodules, and the C-TIRADS has the best overall efficacy, which can effectively assist clinicians for medical decision, and is worth to be popularized and applied in the clinical setting.

Abstract
Objective: To evaluate the prognosis and determine the failure patterns after radiotherapy for low-risk early-stage patients with extranodal NK/T-cell lymphoma, nasal-type (ENKTCL). Methods: A total of 557 patients from 2000-2015 with low-risk early-stage ENKTCL who received radiotherapy (RT) with or without chemotherapy (CT) from China Lymphoma Collaborative Group were retrospectively reviewed. Among them, 427 patients received combined modality therapy, whereas 130 patients received RT alone. Survivals were calculated by Kaplan-Meier method and compared with Log-rank test. Overall survival (OS) was compared with age and sex-matched general Chinese population using expected survival and standardized mortality ratio (SMR). Cox stepwise regression model was used for multivariate analysis. Results: The 5-year OS and progression-free survival (PFS) were 87.2% and 77.2%. The SMR was 3.59 (P<0.001) at 1 year after treatment, whereas it was 1.50 at 4 years after treatment, without significant difference between ENKTCL group and country-matched general population (P=0.146). Compared with RT alone, CMT did not result in significantly superior 5-year OS (87.0% vs 87.4%, P=0.961) or PFS (76.1% vs 80.7%, P=0.129). Local failure (11.5%, 64/557) and distant failure (10.8%, 60/557) were the main failure modes, while regional failure was rare (2.9%, 16/557). The 5-year locoregional control rate (LRC) was 87.2% for the whole group, with 89.5% for ≥50 Gy versus 73.7% for <50 Gy (P<0.001). Radiotherapy dose was an independent factor affecting LRC(P<0.05). Conclusions: Radiotherapy achieves a favorable prognosis in patients with low-risk early-stage ENKTCL. The incidence of either locoregional or distant failure is low. Radiation dose still is an important prognostic factor for LRC.

Abstract
OBJECTIVE The incidence of thyroid cancer is rising globally. Most patients progress slowly, but some patients develop lymph node and distant metastasis earlier, and their prognosis is poor. Therefore, early diagnosis and warning of malignancy are very meaningful for such patients. SAS1B gene is a newly discovered protein expressed on the surface of mature egg cells and has metalloendopeptidase activity. We aimed at exploring whether SAS1B is involved in the occurrence of thyroid cancer, and at providing evidence for early diagnosis and targeted therapy of thyroid cancer. PATIENTS AND METHODS In this study, a rabbit anti-human SAS1B polyclonal antibody was prepared by gene recombination technology. The indirect ELISA method was used to detect the SAS1B protein expression in the serum of 69 patients with thyroid cancer and 55 normal controls, and the relevant pathological factors were analyzed. Immunohistochemistry and PCR technology were used to investigate the expression levels of SAS1B protein and mRNA in 30 thyroid cancer tissues and 23 control thyroid tissues. RESULTS The titer of SAS1B recombinant antibody was 1:51200. The expression of SAS1B in the serum of patients with thyroid cancer was higher than that in the normal control group (p<0.01). The antibody had a good sensitivity in serum detection of cancer patients (p=0.008<0.01), the linear regression analysis result was that the expression of SAS1B gene was related to tumor envelope invasion and lymph node metastasis (p=0.003<0.01, p=0.003<0.01), and it was irrelevant to the patient's gender, age, tumor mass size, number of cancer foci, pathological stage, etc. (p>0.05). The results of immunohistochemistry showed that SAS1B protein was mainly located in the cytoplasm and membrane of thyroid cancer cells. The expression intensity in thyroid cancer tissues was higher than that in control tissues (p<0.05), but it was not expressed in normal thyroid tissues. Antibodies showed a good sensitivity that was used to detect thyroid cancer tissues (p=0.000<0.01). The results of ordinary PCR detection using thyroid cancer tissue and control thyroid tissue showed that the amplification products of the three domains (N-terminal, C-terminal and catalytic domain) of the SAS1B gene showed high expression in thyroid cancer tissue. q-PCR results showed that the expression of SAS1B gene in thyroid cancer and control thyroid tissue was higher than that in control group (p<0.05), and the genes of Aurora A and BARD1 related to centrosome replication and DNA replication forks protection during the proliferation were highly expressed in thyroid cancer tissue. The study results suggested that SAS1B was involved in the carcinogenesis of thyroid cancer. The Hum_mPLoc.2.0 software, PSORT Ⅱ software and UniProt software were used to predict that SAS1B protein had secretory protein properties. CONCLUSIONS The above data indicate that the SAS1B gene is closely related to the process of thyroid cancer and can serve as a good tumor marker that can be used for early diagnosis and early warning of thyroid malignancy.

Abstract
BACKGROUND Dupilumab is an antibody against interleukin 4 receptor α, used in treating atopic dermatitis (AD). OBJECTIVES To evaluate the efficacy and safety of dupilumab in adult Chinese patients with moderate-to-severe AD. METHODS In this randomized, double-blind, placebo-controlled, parallel-group, phase III study, conducted between December 2018 and February 2020, patients with AD received dupilumab (300mg) or placebo once every 2 weeks for 16 weeks, and were followed up for 12 weeks. The primary efficacy endpoint was the proportion of patients with both Investigator's Global Assessment (IGA) score of 0-1 and a reduction from baseline of ≥2 points at week 16. RESULTS Overall, 165 patients (mean age: 30.6 years; 71.5% male) were randomized: 82 to dupilumab and 83 to placebo. At week 16, 26.8% of patients in the dupilumab group and 4.8% of patients in the placebo group achieved the primary endpoint (difference, 22.0%; 95% confidence interval [CI], 11.37-32.65%; p<0.0001). Compared with placebo, higher proportions of patients in the dupilumab group achieved ≥75% reduction in the Eczema Area and Severity Index score (57.3% vs 14.5%; difference, 42.9%; 95% CI, 29.75-55.97%; p<0.0001) and had ≥3-point (52.4% vs 9.6%; difference, 42.8%; 95% CI, 30.26-55.34%; p<0.0001) and ≥4-point (39.0% vs 4.8%; difference, 34.2%; 95% CI, 22.69-45.72%; p<0.0001) reductions in weekly average daily peak daily pruritus numerical rating scale scores. The incidence of TEAEs during the treatment period was similar in the two groups. The incidence of conjunctivitis, allergic conjunctivitis, and injection site reaction was higher in the dupilumab group than in the placebo group. CONCLUSIONS In adult Chinese patients, dupilumab was effective in improving the signs and symptoms of AD and demonstrated a favorable safety profile.

Abstract
Objective: To evaluate the efficacy of endovascular stenting of various types of venous sinus stenosis in idiopathic intracranial hypertension (IIH). Method: Clinical, radiological, and manometric data before and after stenting in venous sinus stenosis were retrospectively analyzed in 99 IIH patients who were refractory to medical therapy or rapidly progressed between July 2004 to July 2019. The follow-up period was between 2.3 months to 11 years. Results: Our study enrolled 21 men (21.2%)and 78 women (78.8%) with average body mass index (BMI) 19.2-40.6(27.0±4.4) kg/m2 and median age 37 years. Before stent placement, the mean transverse sinus stenosis gradient was 1-59(26±8) mmHg. Patients with extrinsic stenosis were younger than those with intrinsic and mixed stenosis. In all cases, stenting was effective for papilledema. Fifty patients complained of headaches. Pulsatile tinnitus in twenty-eight patients completely alleviated after stenting. In one patient, replacement of stent did not improve symptoms, and a subsequent CSF diversion procedure was performed and effective. Conclusion: Irrespective of the type of stenosis, stenting of venous sinus stenosis is an effective treatment for IIH. Patients with persistent papilledema post-stenting and elevated transverse pressure pre-stenting should be followed closely as high risk of stenting failure may occur and further diversion procedure is needed.

Abstract
OBJECTIVE To explore the incidence of enteral feeding intolerance and its risk factors in patients with malignant oral and maxillofacial tumors. METHODS We conducted a retrospective analysis of 122 patients with malignant oral and maxillofacial tumor admitted in a general hospital for enteral nutrition between March, 2018 and March, 2021. The incidence of intolerance to enteral nutrition was analyzed, and the two groups of patients with and without intolerance were compared for age, gender, height, weight, pathological staging, types of enteral nutrition preparations, clinical treatment (physical hypothermia and nasal delivery), drug usage (sedatives, vasoactive drugs, acid suppressant, potassium preparation, antibiotics and hormones) and biochemical parameters (serum total protein, serum albumin, blood glucose and serum potassium concentration). Logistic regression analysis was used to analyze the influencing factors of enteral nutritional feeding intolerance in patients. RESULTS Of the 122 patients, 52 had enteral feeding intolerance with an incidence rate of 42.6%. Logistic regression analysis showed that potassium preparation (OR=4.125, P=0.027, 95%CI: 1.178-14.444), sedatives (OR=4.125, P=0.000, 95%CI: 2.007-11.765) and hypoproteinemia (OR=3.557, P=0.010, 95%CI: 1.351-9.366) were independent risk factors of feeding intolerance in patients with malignant oral and maxillofacial tumors, while adding dietary fiber was a protective factor (OR= 0.108, P=0.015, 95%CI: 0.018-0.643). CONCLUSION The incidence of enteral feeding intolerance is high in patients with malignant oral and maxillofacial tumors. Enteral nutrition preparations with dietary fiber are recommended for these patients. The patients with potassium preparations, sedatives and hypoproteinemia should be closely monitored for enteral feeding intolerance, and timely intervention should be administered to reduce its incidence.

Abstract
BACKGROUND This study evaluated the survival benefit of asparaginase (ASP)-based versus non-ASP-based chemotherapy combined with radiotherapy in a real-world cohort of patients with early-stage extranodal nasal-type natural killer/T-cell lymphoma (ENKTCL). PATIENTS AND METHODS We identified 376 patients who received combined radiotherapy with either ASP-based (ASP, platinum, and gemcitabine; n = 286) or non-ASP-based (platinum and gemcitabine; n = 90) regimens. The patients were stratified into low-, intermediate-, and high-risk groups using the early stage-adjusted nomogram-revised risk index. Overall survival (OS) and distant metastasis (DM)-free survival (DMFS) between the chemotherapy regimens were compared using inverse probability of treatment weighting (IPTW) and multivariable analyses. RESULTS ASP-based (versus non-ASP-based) regimens significantly improved 5-year OS (84.5% versus 73.2%, P = 0.021) and DMFS (84.4% versus 74.5%, P = 0.014) for intermediate- and high-risk patients, but not for low-risk patients in the setting of radiotherapy. Moreover, ASP-based regimens decreased DM, with a 5-year cumulative DM rate of 14.9% for ASP-based regimens compared with 25.1% (P = 0.014) for non-ASP-based regimens. The survival benefit of ASP-based chemotherapy and radiotherapy remained consistent after adjusting the confounding variables using IPTW and multivariate analyses; additional sensitivity analyses confirmed these results. CONCLUSIONS The findings provided support for ASP-based chemotherapy and radiotherapy as a first-line treatment strategy for intermediate- and high-risk early-stage ENKTCL.

Abstract
The measurement of the energy spectrum of cosmic ray helium nuclei from 70 GeV to 80 TeV using 4.5 years of data recorded by the Dark Matter Particle Explorer (DAMPE) is reported in this work. A hardening of the spectrum is observed at an energy of about 1.3 TeV, similar to previous observations. In addition, a spectral softening at about 34 TeV is revealed for the first time with large statistics and well controlled systematic uncertainties, with an overall significance of 4.3σ. The DAMPE spectral measurements of both cosmic protons and helium nuclei suggest a particle charge dependent softening energy, although with current uncertainties a dependence on the number of nucleons cannot be ruled out.

Abstract
Objective: To examine the safety and feasibility of using fusion indocyanine green fluorescence imaging (FIGFI) technique for intraoperative evaluation of colorectal perfusion in the totally laparoscopic left colectomy. Methods: A retrospective cohort study was conducted to collect the clinical data of 58 patients with left colon cancer who underwent totally laparoscopic surgery at the Colorectal Surgery Department, Cancer Hospital, Chinese Academy of Medical Sciences from October 2016 to December 2019. There were 39 males and 19 females, aging (57.0±10.1)years(range:28 to 75 years). According to whether the FIGFI was used during the operation, they were divided into 36 cases in the study group and 22 cases in the control group. The clinical pathological characteristics, operative and postoperative recovery of the two groups were compared by t test, χ2 test, and Fisher exact test. Results: All the 58 patients underwent R0 resection with totally laparoscopic surgery. In the study group, due to poor bowel blood flow after cutting the mesentery (Sherwinter score = 1), 1 patient had to be expanded the resection range until the blood flow was rich(Sherwinter score≥3), and 1 patient in the control group had the complication of postoperative anastomotic leakage of grade A. Compared with the control group, the operation time in the study group was shorter ((156.3±43.5) minutes vs. (180.4±41.3) minutes, t=-2.083, P=0.042). However, there were no significant differences in the amount of blood loss, postoperative hospital stay, postoperative time of anal exhaust, length of bowel resection, number of lymph nodes dissected, and in the incidence of postoperative complications between the two groups. Median follow-up period was 23 months (range: 18 to 37 months). There were no long-term postoperative complications such as ischemic enteritis and anastomotic stenosis in both groups. Conclusions: The FIGFI is safe and feasible to assess the blood supply of intestinal segment and anastomosis during totally laparoscopic left hemicolectomy, and is easy to operate. It is expected to reduce the incidence of anastomotic leakage.

Abstract
OBJECTIVES Diurnal temperature range (DTR) is an important indicator of global climate change. Many epidemiological studies have reported the associations between high DTR and human health. This study investigated the association between DTR and hospitalisations for ischaemic stroke in Hefei, China. STUDY DESIGN This is an ecological study. METHODS Data of daily hospital admissions for ischaemic stroke and meteorological variables from 1 January 2009 to 31 December 2017 were collected in Hefei, China. A generalised additive model combined with distributed lag non-linear model was used to quantify the effects of DTR on ischaemic stroke. The interactive effect between DTR and temperature was explored with a non-parametric bivariate response surface model. RESULTS High DTR was associated with hospitalisations for ischaemic stroke. The adverse effect of extremely high DTR (99th percentile [17.1 °C]) occurred after 8 days (relative risk [RR] = 1.021, 95% confidence interval [CI] = 1.002, 1.041) and the maximum effect appeared after 12 days (RR = 1.029, 95% CI = 1.011, 1.046). The overall trend of the effect of DTR on ischaemic stroke was decreasing. In addition, there was a significant interactive effect of high DTR and low temperature on ischaemic stroke. CONCLUSIONS This study suggests that the impact of high DTR should be considered when formulating targeted measures to prevent ischaemic stroke, especially for those days with high DTR and low mean temperature.
