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 explore the mechanism of electroacupuncture (EA) at "Fengchi" (GB 20) and "Sishencong" (EX-HN 1) on learning and memory impairment in vascular dementia (VD) rats by observing the influences on the N-methyl-D-aspartate receptor (NMDAR)/cyclic adenosine monophosphate response element-binding protein (CREB)/brain-derived neurotrophic factor (BDNF) signaling pathway and the excitotoxicity induced by hippocampal calcium overload. METHODS: Thirty-two male SD rats of SPF grade were selected and randomized into a normal group (6 rats), a sham-operation group (6 rats) and an operation group (20 rats). VD model was established with the modified Pulsinelli's four-vessel occlusion (4-VO) method. Twelve rats after successfully modeled were assigned randomly into a model group and an EA group, 6 rats in each one. In the EA group, EA was delivered at bilateral "Fengchi" (GB 20) and "Sishencong" (EX-HN 1), with the continuous wave, the frequency of 2 Hz and the electric current of 1 mA. Stimulation intensity was adjusted depending on the slightly trembling of rat head. EA was given once daily, 30 min each time; and EA intervention was delivered for 21 days continuously. Using Morris water maze test, the learning and memory function was assessed. The neuronal morphology in the hippocampal CA1 was observed with HE staining; the level of glutamate (GLU) in serum and hippocampal tissue, as well as the activity of calcium pump (Ca²⁺-ATP) in the hippocampus were detected using colorimetric method. The protein expression of NMDAR, calmodulin-dependent protein kinase Ⅱ (CaMKⅡ), phosphorylated calmodulin-dependent protein kinase Ⅱ (p-CaMKⅡ), phosphorylated cyclic phosphoradenosine effector element binding proteins (p-CREB), CREB, and BDNF in the hippocampal CA1 was detected using immunohistochemistry. The protein expression of NMDAR, CREB, p-CREB and BDNF in the hippocampal tissue was detected using Western blot method. RESULTS: Compared to the sham-operation group, in the model group, the escape latency was prolonged and the platform crossing times of rats were reduced (P<0.01), the hippocampal neuron structure was damaged to different degrees, the structure in hippocampal CA1 was loosened, the arrangement disorganized, with clear grid-like structure; the neuronal morphology was irregular, pyknosis and even dissolution occurred, glial cells increased, blood capillary was dilated and the inflammatory cells were infiltrated and scattered. The level of GLU in the serum and hippocampal tissue and the protein expression of hippocampal NMDAR were elevated (P<0.01), the activity of Ca²⁺-ATP and the protein expression of CaMKⅡ, p-CaMKⅡ, CREB, p-CREB and BDNF were reduced (P<0.01, P<0.05); and the ratio of p-CaMKⅡ/CaMKⅡ and that of p-CREB/CREB were dropped (P<0.05). In comparison with the model group, in the EA group, the escape latency was shortened and the platform crossing times of rats rose (P<0.01), the arrangement was improved in the hippocampal CA1, the neuronal morphology was intact, the nucleoli were clear relatively and the pyknosis or dissolution were attenuated, the numbers of glial cells reduced relatively, the dilation of blood capillary was alleviated. The level of GLU in the serum and hippocampal tissue and the protein expression of NMDAR were reduced in the hippocampal tissue (P<0.01), the activity of Ca²⁺-ATP and the protein expression of CaMKⅡ, p-CaMKⅡ, CREB, p-CREB and BDNF were elevated (P<0.05, P<0.01); and the ratio of p-CaMKⅡ/CaMKⅡ and that of p-CREB/CREB increased (P<0.05). CONCLUSION EA at "Fengchi" (GB 20) and "Sishencong" (EX-HN 1) can attenuate learning and memory impairment in VD rats, which may be obtained by reducing GLU level in hippocampal tissue, inhibiting hippocampal excitotoxicity, mediating protein expression related to the NMDAR/CREB/BDNF signaling pathway, and maintaining neuronal survival and growth.

The clinicopathological data of 385 patients with proximal gastric cancer and adenocarcinoma of esophagogastric junction who underwent LPG in the 15 medical centers, including the First Affiliated Hospital of Xiamen University et al, from January 2014 to March 2022 were collected. There were 304 males and 81 females, aged (63±9)years. Of the 385 patients, 335 cases undergoing LPG were divided into the laparoscopic group and 50 cases undergoing open proximal gastrectomy were divided into the open group. Observation indicators: (1) intraoperative and postoperative situations; (2) follow-up; (3) stratified analysis. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribution were represented as M(range), and comparison between groups was conducted using the Wilcoxon rank sum test. Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test or Fisher exact probability. Repeated measurement data were analyzed using the repeated ANOVA. Results:(1) Intraoperative and postoperative situations. The operation time, cases with reconstruction of digestive tract as esophagogastric anastomosis and esophageal-jejunal anastomosis, cases with postoperative pathological staging as stage 0?Ⅰ and stage Ⅱ?Ⅲ, duration of postoperative hospital stay, cases with postoperative early complications were (212±96)minutes, 270, 65, 177, 107, 10(range, 8?14)days, 40 in patients of the laparoscopic group, with 51 cases missing the data of postoperative pathological staging. The above indicators were (174±90)minutes, 39, 11, 22, 28, 10(range, 8?18)days, 10 in patients of the open group.

Objective To investigate the basic situation of radiodiagnosis and radiotherapy institutions and the frequency of medical exposure in Fangshan District, Beijing, China. Methods A general survey using the questionnaire was conducted online to obtain the basic situation of the radiodiagnosis and radiotherapy institutions, the number of people in each type of radiodiagnosis and radiotherapy project, and the number of the usually resident population in the whole district in 2019, thus obtaining the frequency of medical exposure in each type of radiodiagnosis and radiotherapy project. Results There were 60 radiodiagnosis and radiotherapy institutions, 565 radiology staff, and 199 sets of radiodiagnosis and radiotherapy equipment in the whole district in 2019. The frequency of medical exposure was 521.29 per 1000 people, among which conventional medical diagnostic X-ray workers accounted for 301.79 per 1000 people (57.89%) and computed tomography workers accounted for 207.56 per 1000 people (39.82%). The number of tertiary hospitals accounted for 6.67% of the radiodiagnosis and radiotherapy institutions, and the number of people exposed tomedical radiation in tertiary hospitals accounted for 52.25% of the total. The number of secondary hospitals accounted for 5.00% of the radiodiagnosis and radiotherapy institutions, and the number of people exposed to medical radiation in secondary hospitals accounted for 27.83% of the total. Conclusion The distribution of medical exposure in Fangshan District is uneven. The radiodiagnosis and radiotherapy technology used is relatively single. Relevant departments should strengthen macroscopic readjustment and control, and formulate reasonable policies, so as to rationally allocate and effectively utilize medical and health resources.

【Objective】 To obtain the quality information of von Willebrand factor (vWF) in coagulation factor Ⅷ (FⅧ) concentrates in China. 【Methods】 FⅧ concentrates produced by 7 domestic blood product manufactures and 1 foreign manufacture were collected, then FⅧ and vWF contained in FⅧ concentrates were evaluated. 【Results】 The activity loss of vWF was more than 25% in 2 of the 7 domestic FⅧ concentrates. The ratio of vWF activity to FⅧ activity in FⅧ concentrates from different domestic manufactures was significantly different (P<0.05). The ratio in FⅧ concentrates prepared by C, D, F manufacturer was greater than 1, which was similar to that in willate^@ approved abroad for the treatment of vWD. The ratio in FⅧ concentrates prepared by E manufacturer was greater than 0.7 and less than 1, and by A, B, G manufacturers was less than 0.5. In addition, the specific activities of FⅧ and vWF were significantly different among different FⅧ concentrates in China (P<0.05), and the specific activities of FⅧ and vWF were much lower than that of willate^@. 【Conclusion】 The variation of vWF quality between domestic FⅧ concentrates and willate^@ is mainly due to the different in vWF content. After the comprehensive consideration of various indicators, the FⅧ concentrates made by C and D manufacturers may be used in the treatment of vWD.

Objective: To investigate the effects of costunolide (Cos) on the proliferation, apoptosis, migration andinvasion of cholangiocarcinoma RBE cells, and explore its potential mechanism. Methods: The CCK-8, flow cytometry,Annexin V-FITC/PI double staining, Transwell assays were used to examine the influence of Cos on proliferation, cell cycle, apoptosis, migration and invasion of RBE cells after treated with gradient concentrations of Cos. The expressions of M M P 2 and M M P 9 were detected by qRT-PCR, and the expression of PI3K/AKT-associated signal proteins was detected by Western blotting. Results: Cosdose-dependently inhibited proliferation activity of RBE cells( P <0.05 or P <0.01), arrested cell cycle at S and G2/M phases and induced RBE cell apoptosis( P <0.01). Transwell and qRT-PCR results demonstrated that Cos impeded RBE cell migration, invasion, and reduced the transcription of M M P 2 and M M P 9 . Cos inhibited the expressionofp-AKT, Bcl-2, MMP2 and MMP9, the level of Bax. Conclusion: Cos restrained the proliferation, migration and invasion of RBE cells by suppressing PI3K/AKTpathway.

Objective: To explore the impact of exercise rehabilitation on cardiac function in coronary artery disease (CAD) patients after percutaneous coronary intervention (PCI). Methods: A total of 130 CAD patients received primary PCI in our hospital from 2014-01 to 2015-09 were enrolled. All patients received conventional drug therapy and post-PCI knowledge education, then were randomly divided into 2 groups: Conventional group and Rehabilitation group, in which the patients received cardiac rehabilitation exercise for 3 months at different stage and intensity. n=65 in each group. The cardiac function including left ventricular ejection fraction (LVEF), left ventricular end-diastolic diameter (LVEDD), 6 min walking distance (6MWD) and NYHA classification were compared between 2 groups at 1, 3 and 6 months after the operation. Results: LVEF, LVEDD, 6MWD and NYHA classification were similar between 2 groups at enrollment, P>0.05. ① At 1 month post-operation: 6MWD was different between 2 groups, P<0.05, while LVEF, LVEDD, NYHA classification and the recurrence rate of angina pectoris were similar between 2 groups, P>0.05. In Rehabilitation group, 6MWD and NYHA classification were different from the enrollment condition, P<0.05, while other parameters were similar, P>0.05; in Conventional group, 6MWD was different from the enrollment condition, P<0.05, while other parameters was similar, P>0.05. ② At 3 and 6 months post-operation: all parameters were different between 2 groups, P>0.05. In Rehabilitation group, all parameters were different from the enrollment condition, P<0.05. ③ In Conventional group, at 3 months post-operation: LVEDD and 6MWD were different from the enrollment condition, P<0.05; at 6 months post-operation: 6MWD was different from the enrollment condition, P<0.05. Conclusion: Exercise rehabilitation may improve the cardiac function, therefore enhance the endurance capacity and quality of life in CAD patients after PCI.

Objective To investigate the incidence of extra intestinal organ damage in infants with acute rotavirus (RV) infection,the relative risk factors in patients with extra intestinal organ damage,the significance of procalcitonin(PCT)in those infants with multiple organ injury.Methods One hundred and three infants with acute diarrhea whose rotavirus antigens were positive and 65 negative ones were divided into two groups.The differences between these two groups in incidences of extra intestinal organ damage were analyzed.Meanwhile,variables from the clinical data that may lead to extra intestinal organ damage were analyzed.Then,the relationship of multiple organ damage and serum concentration of PCT was also analyzed.Results There were significant differences between positive group and negative group in the rates of respiratory system injury,myocardial damage and hepatic involvement (P ＜ 0.05).High fever was the only high risk factor in myocardial damage through multi factor Logistic regression analysis.There were also significant differences among the group with multiple organ damage and only one extra intestinal organ damage and no extra intestinal organ damage in serum concentration of PCT(P ＜ 0.05).Conclusion It is common to be attacked by extra intestinal organ damage in infants with acute rotavirus infection.High fever is the risk factor for RV enteritis complicated with myocardial damage.The elevation of PCT concentration suggest that multiple organ injury out of the intestinal tract may take place in infants with acute RV infection.

Objective To evaluate the efficacy and safety of recombinant adenovirus-p53(rAdp53) injection combined with radiotherapy and hyperthermia in the treatment of unresectable advanced soft tissue sarcoma.Methods In this retrospective study, we evaluated 76 patients with unresectable advanced primary or recurrent soft tissue sarcoma treated in our hospital from November 2005 to November 2012.These patients received radiotherapy and hyperthermia with rAdp53(p53 group, n=41) or without rAdp53(control group, n=35).rAdp53((1-2)×1012viral particles each time, once a week, 8 times on average) was injected into the tumor or infused into the pelvic cavity.Radiotherapy (2 Gy each time, 5 times a week) was performed for the planning target volume at 56.3±5.3 Gy in the p53 group and 58.1±4.2 Gy in the control group, with no significant difference between the two groups (P>0.05).Superficial or deep thermotherapy was employed 8 times on average (twice a week).Clinical features, response rate, time to progression (TTP), overall survival (OS), and adverse events were compared between the two groups (P>0.05).The Kaplan-Meier method was used to calculate OS;the log-rank test was used for survival difference analysis and univariate prognostic analysis;the chi-square test was used for comparison of categorical data.Results At 2 months after treatment, the p53 group had significantly increased response rate (partial response+ complete response+ stable disease)(85% vs.54%, P=0.003) and local control rate (49% vs.23%, P=0.020) as well as prolonged TTP (12 months vs.5 months, P=0.010) and OS (48 months vs.31 months, P=0.049), as compared with the control group.No adverse events caused by radiotherapy and hyperthermia except transient fever were seen in the two groups.Conclusions Concurrent radiotherapy and hyperthermia combined with rAdp53 injection is effective and safe for patients with advanced soft tissue sarcoma.
