Objective:To investigate the incidence of postoperative complications in Chinese patients with gastric or colorectal cancer, and to evaluate the risk factors for postoperative complications.Methods:This was a national, multicenter, prospective, registry-based, cohort study of data obtained from the database of the Prevalence of Abdominal Complications After Gastro- enterological Surgery (PACAGE) study sponsored by the China Gastrointestinal Cancer Surgical Union. The PACAGE database prospectively collected general demographic characteristics, protocols for perioperative treatment, and variables associated with postoperative complications in patients treated for gastric or colorectal cancer in 20 medical centers from December 2018 to December 2020. The patients were grouped according to the presence or absence of postoperative complications. Postoperative complications were categorized and graded in accordance with the expert consensus on postoperative complications in gastrointestinal oncology surgery and Clavien-Dindo grading criteria. The incidence of postoperative complications of different grades are presented as bar charts. Independent risk factors for occurrence of postoperative complications were identified by multifactorial unconditional logistic regression.Results:The study cohort comprised 3926 patients with gastric or colorectal cancer, 657 (16.7%) of whom had a total of 876 postoperative complications. Serious complications (Grade III and above) occurred in 4.0% of patients (156/3926). The rate of Grade V complications was 0.2% (7/3926). The cohort included 2271 patients with gastric cancer with a postoperative complication rate of 18.1% (412/2271) and serious complication rate of 4.7% (106/2271); and 1655 with colorectal cancer, with a postoperative complication rate of 14.8% (245/1655) and serious complication rate of 3.0% (50/1655). The incidences of anastomotic leakage in patients with gastric and colorectal cancer were 3.3% (74/2271) and 3.4% (56/1655), respectively. Abdominal infection was the most frequently occurring complication, accounting for 28.7% (164/572) and 39.5% (120/304) of postoperative complications in patients with gastric and colorectal cancer, respectively. The most frequently occurring grade of postoperative complication was Grade II, accounting for 65.4% (374/572) and 56.6% (172/304) of complications in patients with gastric and colorectal cancers, respectively. Multifactorial analysis identified (1) the following independent risk factors for postoperative complications in patients in the gastric cancer group: preoperative comorbidities (OR=2.54, 95%CI: 1.51-4.28, P<0.001), neoadjuvant therapy (OR=1.42, 95%CI:1.06-1.89, P=0.020), high American Society of Anesthesiologists (ASA) scores (ASA score 2 points:OR=1.60, 95% CI: 1.23-2.07, P<0.001, ASA score ≥3 points:OR=0.43, 95% CI: 0.25-0.73, P=0.002), operative time >180 minutes (OR=1.81, 95% CI: 1.42-2.31, P<0.001), intraoperative bleeding >50 mL (OR=1.29,95%CI: 1.01-1.63, P=0.038), and distal gastrectomy compared with total gastrectomy (OR=0.65,95%CI: 0.51-0.83, P<0.001); and (2) the following independent risk factors for postoperative complications in patients in the colorectal cancer group: female (OR=0.60, 95%CI: 0.44-0.80, P<0.001), preoperative comorbidities (OR=2.73, 95%CI: 1.25-5.99, P=0.030), neoadjuvant therapy (OR=1.83, 95%CI:1.23-2.72, P=0.008), laparoscopic surgery (OR=0.47, 95%CI: 0.30-0.72, P=0.022), and abdominoperineal resection compared with low anterior resection (OR=2.74, 95%CI: 1.71-4.41, P<0.001). Conclusion:Postoperative complications associated with various types of infection were the most frequent complications in patients with gastric or colorectal cancer. Although the risk factors for postoperative complications differed between patients with gastric cancer and those with colorectal cancer, the presence of preoperative comorbidities, administration of neoadjuvant therapy, and extent of surgical resection, were the commonest factors associated with postoperative complications in patients of both categories.

Objective To investigate the clinical efficacy of therapy of clearing heat,percolating dampness and lowering turbidity combined with Silibin Meglumine Tablets in the treatment of non-alcoholic steatohepatitis(NASH)patients with abnormal alanine aminotransferase(ALT)level of damp-heat accumulation type.Methods A retrospective study was conducted.According to the medication,80 patients with NASH with abnormal ALT level of damp-heat accumulation type were divided into control group and observation group,with 40 cases in each group.The control group was treated with Silibin Meglumine Tablets,and the observation group was treated with therapy of clearing heat,percolating dampness and lowering turbidity on the basis of treatment for the control group.The course of treatment covered 12 weeks.The changes of liver function indicators of ALT,aspartate aminotransferase(AST),and gamma glutamyl transpeptidase(GGT),blood lipid indicators of total cholesterol(CHOL)and triglyceride(TRIG),and the degree of hepatic steatosis in the two groups were observed before and after treatment.After treatment,the clinical efficacy and safety of the two groups were evaluated.Results(1)After 12 weeks of treatment,the total effective rate of the observation group was 95.00%(38/40),and that of the control group was 77.50%(31/40).The curative effect of the observation group was significantly superior to that of the control group,and the difference was statistically significant(P＜0.05).(2)After treatment,the levels of ALT,AST and GGT in the two groups were significantly lower than those before treatment(P＜0.05),and the decrease of ALT,AST and GGT in the observation group was significantly superior to that in the control group(P＜0.05).(3)After treatment,the levels of CHOL and TRIG in the two groups were significantly lower than those before treatment(P＜0.05),and the decrease of CHOL and TRIG in the observation group was significantly superior to that in the control group(P＜0.05).(4)After treatment,the degree of hepatic steatosis in the two groups was significantly lower than that before treatment(P＜0.05),and the decrease of the degree of hepatic steatosis in the observation group was significantly superior to that in the control group(P＜0.05).(5)During the treatment,no obvious adverse reactions occurred in the two groups,indicating high safety.Conclusion The therapy of clearing heat,percolating dampness and lowering turbidity combined with Silibin Meglumine Tablets exerts certain effect in the treatment of NASH patients with abnormal ALT level of damp-heat accumulation type,and the therapy can significantly enhance the clinical efficacy of Silibin Meglumine Tablets alone for NASH.

Objective To analyze the stress changes of thoracic vertebra(T)11-sacrum(S)titanium rods in patients with ankylosing spondylitis after vertebral column decancellation(VCD)osteotomy,and provide reference for the selection and improvement of titanium rods before surgery.Methods The original data of the continuous scanning tomographic images of patients with ankylosing spondylitis after VCD osteotomy were imported into Mimics 21.0 in DICOM format,and T11-S vertebrae,screws and titanium rods were respectively reconstructed.They were imported into 3-Matic to establish a preliminary geometric modeling,and then processed with noise removal,paving,smoothing,etc.The improved model was imported into Hypermesh 10 software for grid division,and the material was imported into ANSYS 19.2 to display the finite element model after attribute assignment,Set the boundary and load conditions,and measure the stress value at the connection between the screw and the titanium rod.Results Under neutral position,forward bending,lateral bending,and axial rotation conditions,the titanium rod had the highest stress at the upper vertebrae(T11)and the lowest stress at the top vertebrae(L3);Under the backward extension condition,the titanium rod has the highest stress at the lower end vertebra(L5).Conclusion In the upper and lower vertebrae,it is possible to consider increasing the diameter of the titanium rod,enhancing its hardness,or changing it to a double rod.

Objective:To investigate the relationship between cancer node status identified after radical resection and patterns of recurrence in stage Ⅱ/Ⅲ gastric cancer patients for developing personalized follow-up plans in node-positive patients.Methods:A retrospective analysis was conducted on 706 stage Ⅱ/Ⅲ gastric cancer patients who underwent curative intent surgery at Henan Cancer Hospital from Sep 2015 to Sep 2018. Patients were categorized into node-positive (TDs +) and node-negative (TDs -) groups based on their cancer node status. Clinical-pathological characteristics and recurrence patterns were compared between the groups to formulate an optimized follow-up plan. Results:Among the patients, there were 112 TDs + and 594 TDs - cases. TDs - patients exhibited significantly better overall survival and disease-free survival rates at 1 and 3 years compared to the TDs + group (92.4%,72.2% vs. 79.4%,38.8%;87.9%,68.6% vs. 66.7%,35.9%, all P<0.05). The cumulative recurrence rates of peritoneal and distant metastases were higher in TDs + patients compared to TDs - patients, with statistical significance (33.0% vs. 14.5%,21.4% vs. 10.8%, χ 2=21.285,8.851 all P<0.05). TDs + patients experienced significantly earlier median time to distant metastasis compared to TDs - patients (9.0 months vs. 15.4 months , Z=-2.294 P=0.022). The risk of peritoneal metastasis recurrence was higher in the TDs + group, showing a bimodal recurrence pattern at 8.5 and 15.0 months post-surgery. TDs + patients also had a higher risk of distant metastasis recurrence, with a single peak at 6 months. Conclusion:Postoperative recurrence patterns differ between TDs + and TDs - patients, and an optimized follow-up plan can enhance early detection of recurrence.

Objective To investigate the predictive value of systemic immune inflammation index(SII)scores in long-term survival of patients with stage Ⅲ squamous lung cancer treated with radical radiotherapy.Methods Clinical data of stage Ⅲ squamous lung cancer patients who underwent radical radiotherapy at the Radiotherapy Department of the Fourth Hospital of Hebei Medical University from January 2010 to December 2018 were retrospectively analyzed.The peripheral hematological indexes one week before radiotherapy were collected and recorded.X-Tile software was applied to determine the best cut-off values for continuous variables.Kaplan-Meier method was used to analyze overall survival(OS)and progression-free survival(PFS).Results A total of 453 patients were included in this study.There were 336 patients in the low SII group(＜1 277.3),and other 117 patients were in the high SII group(≥1 277.3).The median OS and median PFS in the high SII group were shorter than those in the low SII group(OS:20.8 months vs.31.0 months,Log-rank χ2=18.015,P＜0.01;PFS:13.0 months vs.21.0 months,Log-rank χ2=15.062,P＜0.01).Multivariate Cox regression analysis showed that high SII was associated with OS(HR=1.628,95%CI:1.294-2.047,P<0.001)and PFS(HR=1.559,95%CI:1.240-1.961,P<0.001).Other influencing factors included late TNM stage,poor radiotherapy efficacy and decreased HALP score.Conclusion SII can be used to evaluate the long-term survival of patients with stage Ⅲ lung squamous cell carcinoma receiving radical radiotherapy,and the increase of SII indicates a poor prognosis.

Objective:To establish a nomogram to predict overall survival of patients with stage Ⅰ-Ⅲ gastric cancer (GC) based on preoperative inflammatory markers.Methods:Clinicopathological and follow-up data of 1 035 patients with stage Ⅰ-Ⅲ gastric cancer operated at He'nan Cancer Hospital between May 2015 and Oct 2016 were retrospectively collected. A nomogram was established based on prognostic factors. Harrell's concordance index (C-index), receiver operating characteristic (ROC) curve, calibration curve and decision curve analysis (DCA) were used to verify the performance of the model according to differentiation, calibration and clinical utility.Results:A total of 1 035 patients were enrolled . The median follow-up time was 41.9 months; According to the optimal cutoff value, 170 were with elevated neutrophil-to-lymphocyte ratio (NLR) and 865 with a reduced　ratio; 562 in elevated platelet-to-lymphocyte ratio (PLR) vs. 473 in the reduced group; fibrinogen/albumin ratio (FAR) elevated in 108 group vs. 972 in the reduced group; 180 in the prognostic nutritional index score (PNI) elevated group and 855 in the reduced group. Two hundred and sixty-seven patients were categorized at stage Ⅰ, 334 at stage Ⅱ ,434 at stage Ⅲ. Multivariate regression analysis showed tumor location, vascular tumor thrombus, pTNM stage, FAR, PNI and NLR were independent prognostic factors (all P<0.05). The C-index of the nomogram was 0.723 (95% CI: 0.710 -0.736) and had better clinical utility than the American Joint Committee on Cancer (AJCC) 8th TNM staging system 0.693 (95% CI, 0.681 -0.705). The calibration curve of the nomogram showed that the predicted survival rate was consistent with the actual survival rate in GC patients. Compared to AJCC 8th pTNM staging system, the DCA curve indicate that the nomogram has a higher net income. Conclusion:The nomogram predicting overall survival of patients with stage Ⅰ-Ⅲ gastric cancer is established and verified , which provides better individual prediction than TNM staging system.

Objective: To study the epidemiological and pathogenic characteristics of Vibrio parahaemolyticus isolated from outbreaks cases in Guangdong Province, 2017-2020. Methods: Epidemiological characteristics of 87 outbreak events caused by Vibrio parahaemolyticus were analyzed. Strains were serotyped, and then analyzed by pulsed-field gel electrophoresis (PFGE). Results: The food-borne disease outbreak caused by Vibrio parahaemolyticus was found in 16 cities. 44.8% (39/87) and 37.9% (33/87) of the outbreaks occurred in hotels, restaurants and school canteens, respectively. Improper food processing and storage (40.2%, 35/87) and cross contamination caused by indiscriminate raw and cooked food (25.3%, 22/87) were the main causes of food-borne disease outbreaks of Vibrio parahaemolyticus. The main serotypes of patient derived strains were O3:K6 (87.5%) and O4:KUT (22.5%). The similarity value between O3:K6 type isolates was 65.5%-100.0%, and the PFGE pattern similarity value of O4:KUT type isolates was 66.5%-100.0%. Conclusion: Outbreaks caused by Vibrio parahaemolyticus are widely distributed in Guangdong province. It is necessary to strengthen the publicity and education on the correct handling of food in hotels, restaurants, schools, and unit canteens. O3:K6 and O4:KUT serotypes are the main serotypes of the outbreak. There is genetic diversity among the epidemic strains.
