Objective:To evaluate the safety of double and a half layered esophagojejunal anastomosis in radical gastrectomy.Methods:This prospective, multi-center, single-arm study was initiated by the Affiliated Cancer Hospital of Zhengzhou University in June 2021 (CRAFT Study, NCT05282563). Participating institutions included Nanyang Central Hospital, Zhumadian Central Hospital, Luoyang Central Hospital, First Affiliated Hospital of Henan Polytechnic University, First Affiliated Hospital of Henan University, Luohe Central Hospital, the People's Hospital of Hebi, First People's Hospital of Shangqiu, Anyang Tumor Hospital, First People's Hospital of Pingdingshan, and Zhengzhou Central Hospital Affiliated to Zhengzhou University. Inclusion criteria were as follows: (1) gastric adenocarcinoma confirmed by preoperative gastroscopy;(2) preoperative imaging assessment indicated that R0 resection was feasible; (3) preoperative assessment showed no contraindications to surgery;(4) esophagojejunostomy planned during the procedure; (5) patients volunteered to participate in this study and gave their written informed consent; (6) ECOG score 0–1; and (7) ASA score I–III. Exclusion criteria were as follows: (1) history of upper abdominal surgery (except laparoscopic cholecystectomy);(2) history of gastric surgery (except endoscopic submucosal dissection and endoscopic mucosal resection); (3) pregnancy or lactation;(4) emergency surgery for gastric cancer-related complications (perforation, hemorrhage, obstruction); (5) other malignant tumors within 5 years or coexisting malignant tumors;(6) arterial embolism within 6 months, such as angina pectoris, myocardial infarction, and cerebrovascular accident; and (7) comorbidities or mental health abnormalities that could affect patients' participation in the study. Patients were eliminated from the study if: (1) radical gastrectomy could not be completed; (2) end-to-side esophagojejunal anastomosis was not performed during the procedure; or (3) esophagojejunal anastomosis reinforcement was not possible. Double and a half layered esophagojejunal anastomosis was performed as follows: (1) Open surgery: the full thickness of the anastomosis is continuously sutured, followed by embedding the seromuscular layer with barbed or 3-0 absorbable sutures. The anastomosis is sutured with an average of six to eight stitches. (2) Laparoscopic surgery: the anastomosis is strengthened by counterclockwise full-layer sutures. Once the anastomosis has been sutured to the right posterior aspect of the anastomosis, the jejunum stump is pulled to the right and the anastomosis turned over to continue to complete reinforcement of the posterior wall. The suture interval is approximately 5 mm. After completing the full-thickness suture, the anastomosis is embedded in the seromuscular layer. Relevant data of patients who had undergone radical gastrectomy in the above 12 centers from June 2021 were collected and analyzed. The primary outcome was safety (e.g., postoperative complications, and treatment). Other studied variables included details of surgery (e.g., surgery time, intraoperative bleeding), postoperative recovery (postoperative time to passing flatus and oral intake, length of hospital stay), and follow-up conditions (quality of life as assessed by Visick scores).Result:[1] From June 2021 to September 2022,457 patients were enrolled, including 355 men and 102 women of median age 60.8±10.1 years and BMI 23.7±3.2 kg/m2. The tumors were located in the upper stomach in 294 patients, mid stomach in 139; and lower stomach in 24. The surgical procedures comprised 48 proximal gastrectomies and 409 total gastrectomies. Neoadjuvant chemotherapy was administered to 85 patients. Other organs were resected in 85 patients. The maximum tumor diameter was 4.3±2.2 cm, number of excised lymph nodes 28.3±15.2, and number of positive lymph nodes five (range one to four. As to pathological stage,83 patients had Stage I disease, 128 Stage II, 237 Stage III, and nine Stage IV. [2] The studied surgery-related variables were as follows: The operation was successfully completed in all patients, 352 via a transabdominal approach, 25 via a transhiatus approach, and 80 via a transthoracoabdominal approach. The whole procedure was performed laparoscopically in 53 patients (11.6%), 189 (41.4%) underwent laparoscopic-assisted surgery, and 215 (47.0%) underwent open surgery. The median intraoperative blood loss was 200 (range, 10–1 350) mL, and the operating time 215.6±66.7 minutes. The anastomotic reinforcement time was 2 (7.3±3.9) minutes for laparoscopic-assisted surgery, 17.6±1.7 minutes for total laparoscopy, and 6.0±1.2 minutes for open surgery. [3] The studied postoperative variables were as follows: The median time to postoperative passage of flatus was 3.1±1.1 days and the postoperative gastrointestinal angiography time 6 (range, 4–13) days. The median time to postoperative oral intake was 7 (range, 2–14) days, and the postoperative hospitalization time 15.8±6.7 days. [4] The safety-related variables were as follows: In total, there were 184 (40.3%) postoperative complications. These comprised esophagojejunal anastomosis complications in 10 patients (2.2%), four (0.9%) being anastomotic leakage (including two cases of subclinical leakage and two of clinical leakage; all resolved with conservative treatment); and six patients (1.3%) with anastomotic stenosis (two who underwent endoscopic balloon dilation 21 and 46 days after surgery, the others improved after a change in diet). There was no anastomotic bleeding. Non-anastomotic complications occurred in 174 patients (38.1%). All patients attended for follow-up at least once, the median follow-up time being 10 (3–18) months. Visick grades were as follows: Class I, 89.1% (407/457); Class II, 7.9% (36/457); Class III, 2.6% (12/457); and Class IV 0.4% (2/457).Conclusion:Double and a half layered esophagojejunal anastomosis in radical gastrectomy is safe and feasible.

Objective:To explore the clinical characteristics of elderly patients with type 2 diabetes mellitus (T2DM) complicated with coronary atherosclerotic heart disease (CHD) and analyze the risk factors of CHD in patients with T2DM.Methods:Using the method of retrospective cohort study, 406 elderly male patients with T2DM (≥75 years old) admitted to Xinhua Hospital Affiliated to Shanghai Jiaotong University from January 2017 to January 2020 were selected and divided into T2DM without CHD group (165 cases) and T2DM with CHD group (241 cases). The clinical characteristics in elderly patients with T2DM complicated with CHD and risk factors for CHD were analyzed.Results:The age ((86.78±5.35 )years old), course of T2DM((12.32±0.46) years), fasting blood glucose(FPG)((7.64±2.81) mmol/L), hemoglobin a1c (HbA1c)((7.59±1.21)%), the proportion of hypertension(84.65%(204/241)), D-dimer((0.50±0.13) mg/L), the incidence of thromboembolic events(46.06%(111/241)), blood serum creatinine ((94.81±12.70) μmol/L), urea nitrogen((8.31±4.46) mmol/L), uric acid((376.44±116.01) μmol/L) in T2DM with CHD group were higher than those in T2DM without CHD((78.51±4.81)years old, (10.66±0.67)years, (6.84±2.19) mmol/L, (7.02±2.15)%, 63.03%(104/165), (0.21±0.04 ) mg/L, 13.33%(22/165), (83.01±14.40) μmol/L, (6.79±2.89) mmol/L, (333.56±95.15) μmol/L ), and the differences were statistically significant( t=15.908, t=2.042, t=3.055, t=3.088, χ 2=23.828, t=5.059, χ 2=42.098, t=2.401, t=4.188, t=4.075; all P<0.05). The total bilirubin(TBil)(8.80(6.60, 11.60) μmol/L), glomerular filtration rate(GFR)((76.49±29.80) mL/(min·1.75 m 2)) in T2DM with CHD group were lower than those in T2DM without CHD group (11.25(8.23, 15.28) μmol/L, (91.81±28.31) mL/(min·1.75 m 2)), the differences were statistically significant( Z=2.304, t=5.126; all P<0.001). The total cholesterol((3.84±0.85) mmol/L), low-density lipoprotein cholesterol(LDL-C)((2.12±0.68 ) mmol/L) in T2DM with CHD group were lower than those in T2DM without CHD group((4.10±1.00) mmol/L, (2.45±0.85) mmol/L), the differences were statistically significant( t=2.828, 4.156; all P<0.05). The rate of starting lipid-lowering and stable plaque treatment in T2DM with CHD group (82.57%(199/261))was higher than that in T2DM without CHD group(42.42%(70/165)), and the difference was statistically significant (χ 2=70.614, P<0.001). Influenced by lipid-lowering therapy, the total cholesterol and LDL-C in T2DM patients with CHD were significantly decreased.Logistic regression analysis showed that age elevated( OR 1.346, 95% CI 1.263-1.434, P<0.001), elevated hemoglobin a1c concentration( OR 1.427, 95% CI 1.140-1.785, P=0.002), complicated with hypertension( OR 3.534, 95% CI 1.684-7.418, P=0.001), elevated D-dimer concentration( OR 3.969, 95% CI 1.227-12.841, P=0.021)and elevated uric acid concentration( OR 1.005, 95% CI 1.001-1.008, P=0.006)were independent risk factors for CHD in elderly male patients with T2DM. Conclusion:Elderly patients with T2DM complicated with CHD are more likely to be in hypercoagulable state, more likely to have thromboembolic events, and more obvious renal function damage.Poor fasting blood glucose control and decreased total bilirubin concentration are the influencing factors of CHD in elderly male patients with T2DM.Age elevated, elevated hemoglobin a1c concentration, complicated with hypertension, elevated D-dimer concentration and elevated uric acid concentration are independent risk factors for CHD in elderly male patients with T2DM.

Objective:To investigate the polymorphism of the (MTHFR) C677T and its correlation with the severity of hypertension in Shanxi Province.Methods:A total of 306 patients with essential hypertension from the Second Hospital of Shanxi Medical University from January 2017 to January 2018 were selected as subjects. The clinical data of these patients were extracted from the hospital information system. The biochemistry index, including homocysteine (Hcy) were collected from the hospital laboratory test system and the polymorphism of MTHFR C677T gene was analyzed by polymerase chain reaction (PCR). Logistic regression analysis was used to estimate the severity of hypertension.Results:The frequencies of CC, CT and TT genotypes in patients with essential hypertension in Shanxi were 22.22%, 47.06% and 30.72. The C677T genotype and allele frequency revealed no signifcant departures from Hardy-Weinberg equilibrium in the population from the Shanxi region. Compared with MTHFR 677CC, MTHFR 677CT and MTHFR 677TT genotypes could increase the severity of hypertension by 2.29-fold and 2.24-fold. Smoking, family history of hypertension , Hcy and TG were independent risk factors for increasing the severity of essential hypertension ( OR=2.04, 1.81, 1.04, 1.26). Conclusions:MTHFR C677T genotype, smoking, family history of hypertension, Hcy and triglycerides could be important genetic and high-risk factors for development of severe hypertension , which will help to identify populations at high-risk of hypertension and may facilitate the development of hypertension control strategies.

Myasthenia gravis crisis (MC) often involves respiratory muscles and requires mechanical ventilation urgently. As non-invasive mechanical ventilation (NIV) technology unceasing development, its use in acute respiratory failure caused by MC shows obvious advantages. However, how to identify the occurrence of MC at early stage, predict the relevant indicators of NIV for MC treatment, and apply different ventilation strategies to improve the effect of treatment are worthy of attention. In addition, the new development of NIV modes in recent years also provides new direction for the treatment of MC. Therefore, this article reviews recent advance in the clinical application of NIV in MC to provide clinical references.

Objective:Breast cancer has been the first cancer among women with the incidence increasing gradually. In September 2016, the Breast Cancer Cohort Study in Chinese Women (BCCS-CW) was initiated, aiming to establish a standardized and sharable breast cancer-specific cohort by integrating the existing cohort resource and improving the quality of follow-up. The BCCS-CW may provide a research basis and platform for the precision prevention and treatment of breast cancer in etiology identification, prevention, early diagnosis, treatment, and prognosis prediction.Methods:We conducted a population-based perspective cohort by questionnaire interview, anthropometry, biological specimens, breast ultrasound and mammography. The cohort was followed by using regional health surveillance and ad hoc survey.Results:Finally, BCCS-CW included 112 118 women, in which 55 419 women completed the standardized investigation and blood specimens were collected from 54 304 women. The mean age of participants was 51.7 years old, 62.7% were overweight or obese, and 48.9% were menopausal.Conclusion:The BCCS-CW will provide population-based cohort resource and research platform for the precise prevention and treatment of breast cancer in Chinese women.

It is recommended that cyclophosphamide combined with corticosteroids should be used as the first-line treatment of ANCA ( antineutrophil cytoplasmic antibody) associated with systemic vasculitis ( AASV) , however, cyclophosphamide has notable ad-verse reaction of causing pulmonary fibrosis ( PF) . In this paper, whether cyclophosphamide should be used in an AASF patient with PF was analyzed in order to decide whether AASV with PF is one of contraindications of cyclophosphamide in clinical practice.
