ObjectiveTo systematically evaluate the efficacy and safety of omental wrapping technique for pancreaticojejunal anastomosis in preventing complications after pancreaticoduodenectomy. MethodsThis study was conducted according to the PRISMA guideline. English and Chinese databases including CNKI， Wanfang Data， VIP， CBM， the Cochrane Library， PubMed， Embase， and Web of Science were searched for clinical studies on omental wrapping technique for pancreaticojejunal anastomosis in preventing complications after pancreaticoduodenectomy published up to November 2022， and Stata 16 and Review Manager 5.4 were used to perform the meta-analysis. ResultsA total of 15 studies with 1 830 patients were included in this study. The meta-analysis showed that the omental wrapping group had a significantly lower overall incidence rate of postoperative pancreatic fistula （POPF） than the non-omental wrapping group （odds ratio ［OR］=0.30， 95% confidence interval ［CI］： 0.22‍ ‍—‍ ‍0.41， P<0.001）， and the subgroup analysis showed that the omental wrapping group had a significantly lower incidence rate of grade B/C POPF than the non-omental wrapping group （OR=0.29， 95%CI： 0.21‍ ‍—‍ ‍0.39， P<0.001）. Compared with the non-omental wrapping group， the omental wrapping group had significantly lower incidence rates of postoperative bile leakage （OR=0.30， 95%CI： 0.16‍ ‍—‍ ‍0.56， P<0.001）， postoperative hemorrhage （OR=0.35， 95%CI： 0.24‍ ‍—‍ ‍0.53， P<0.001）， delayed gastric emptying （OR=0.45， 95%CI： 0.31‍ ‍—‍ ‍0.64， P<0.001）， abdominal infection （OR=0.55， 95%CI： 0.40‍ ‍—‍ ‍0.75， P<0.001）， reoperation （OR=0.31， 95%CI： 0.18‍ ‍—‍ ‍0.54， P<0.001）， and death within 30 days after surgery （OR=0.42， 95%CI： 0.22‍ ‍—‍ ‍0.80， P=0.009）， a significantly earlier time to diet （mean difference ［MD］=-0.98， 95%CI： -1.84 to -0.11， P=0.03）， and a significantly shorter length of postoperative hospital stay （MD=-2.44， 95%CI： -4.10 to -0.77， P=0.004）. There were no significant differences between the two groups in the time of operation （MD=-13.68， 95%CI： -28.31 to -0.95， P=0.07） and intraoperative blood loss （MD=-17.26， 95%CI： -57.55 to -23.03， P=0.40）. ConclusionOmental wrapping can reduce the incidence rates of postoperative complications such as pancreatic fistula， bile leakage， postoperative hemorrhage， abdominal infection， and delayed gastric emptying， improve the prognosis of patients， and shorten the length of hospital stay， without increasing surgical difficulty or time of operation.

Periodontitis is associated with abnormal purine metabolism, which is manifested by increased uric acid in host blood and increased expression of the purine-degrading enzyme, xanthine oxidoreductase (XOR), in periodontal tissues. Both XOR and uric acid are pro-oxidative and pro-inflammatory mediators under pathological conditions. Animal studies have found that injection of uric acid promotes the progression of periodontitis and that febuxostat (an XOR inhibitor) improves tissue destruction in periodontitis. Therefore, blocking the source of uric acid may be a therapeutic strategy to control the progression of periodontitis. In this article, the rationality of XOR inhibitors as potential therapeutic drugs for periodontitis is reviewed. The literature review results suggest that XOR inhibitors show antioxidative, anti-inflammatory, and anti-osteoclastic effects, and XOR inhibitors show clinical efficacy in the treatment of infectious, inflammatory and osteolytic diseases. Although there is no direct evidence to support the finding that XOR inhibitors can ameliorate periodontal microecological dysbiosis, these drugs can modulate intestinal microflora dysbiosis, and there is indirect evidence to support a beneficial effect of XOR inhibitors on periodontal microecological dysbiosis. In conclusion, XOR inhibitors may be used as immunomodulators for the adjuvant treatment of periodontitis by inhibiting inflammation, oxidative stress and anti-osteoclast effects.

Objective To explore the relationship between serum iron(SI)metabolism and glucose and lipid metabolism in patients with type 2 diabetes mellitus(T2DM).Methods A total of 170 T2DM patients hospitalized in the Department of Endocrinology,Lanzhou University First Hospital from 2019 to 2021 were included.During the same period,30 healthy individuals from physical examination center were selected as the normal control(NC)group.Based on HbA1c control,T2DM patients were divided into subgroups with good blood glucose control(H1,HbA1c＜7%,n=39),poor glucose control(H2,7%＜HbA1c＜9%,n=63)and very poor glucose control(H3,HbA1c＞9%,n=68).According to the level of blood lipids,T2DM patients were divided into subgroups with normal blood lipids(L1,n=36)and high blood lipids(L2,n=134).Results Compared with NC group,age,SBP,DBP,BMI,serum ferritin(SF),FPG,FIns,HOMA-IR,TyG,TG,LDL-C and SUA increased inT2DM group(P＜0.05),while SI,TF,total iron binding capacity(TIBC),DI,HDL-C and eGFR decreased(P＜0.05).The levels of TF and TIBC in H3 subgroup were lower than those in H1 subgroup(P＜0.05).LDL-C of L2 subgroup was higher than that of L1 subgroup(P＜0.05),while HDL-C was lower than that of L1 subgroup(P＜0.05).Pearson correlation analysis showed that SF was positively correlated with HbA1c,TyG,TG and SUA(P＜0.05),and negatively correlated with HDL-C and eGFR(P＜0.05).TF was positively correlated with HDL-C and eGFR(P＜0.05),but negatively correlated with age,SBP,DBP,TyG and SUA(P＜0.05).Multiple linear regression analysis showed that SF and FPG were influencing factors for HbA1c in T2DM patients.Conclusion SI metabolism is closely related to glucose and lipid metabolism in T2DM patients.

Clinical data of 43 patients who underwent endoscopic resection for gastrointestinal stromal tumors (GIST) of length ≤1.2 cm at the Digestive Endoscopy Center of the 909th Hospital from January 2016 to December 2018 were retrospectively analyzed. The patients were divided into the endoscopic ligation resection (ELR) group ( n=27) and the endoscopic submucosal excavation (ESE) group ( n=16). The general, perioperative and follow-up data of the two groups were compared. The results showed that there was no significant difference in the general data between the two groups. The operation time was 20.0 (18.0,25.0) min in the ELR group and 27.5 (23.0,37.5) min in the ESE group, showing significant difference ( U=92.5, P=0.001). The en bloc resection rates were 100.0% (27/27) in the ELR group and 81.3% (13/16) in the ESE group, showing significant difference ( P=0.045). The postoperative hospital stays were 3 (2,4) days in the ELR group and 5 (4,6) days in the ESE group, showing significant difference ( U=125.5, P=0.020). There was no significant difference in the intraoperative bleeding rate, intraoperative hemorrhage volume, intraoperative perforation rate, number of hemostatic clips or postoperative complications including hemorrhage, fever and peritonitis between the two groups ( P>0.05). During the follow-up, there was no recurrence or metastasis of GIST in both groups. ELR and ESE can be safe and effective for small GIST ≤1.2 cm in diameter. Compared with the ESE group, the operation time and postoperative hospital stay are shorter with higher en bloc resection rate in the ELR group.

Objective:To explore the value and advantages of perioperative nutritional support in enhanced recovery after surgery (ERAS).Methods:The clinical data of patients admitted to Jinjiang City Hospital for acute abdomen and undergoing surgery from April 2018 to January 2021 were collected. They were divided into two groups: the enhanced recovery after surgery group (ERAS group, 78 cases) and the traditional perioperative management group (CPM group, 75 cases). The nutritional risk assessment of NRS2002 was performed on admission to the two groups. The postoperative inflammatory indexes, nutrition and rehabilitation related indexes were compared between the two groups.Results:There was no significant difference in preoperative NRS 2002 score, operation method, operation time and blood loss between ERAS group and CPM group ( P>0.05). There was no significant difference in C-reactive protein (CRP), albumin (Alb) and prealbumin (PA) between ERAS group and CPM group before operation ( P>0.05). The ALb and PA of the two groups on the first day after operation were significantly lower than those before operation, and the CRP levels on the first, third, fifth and seventh day after operation were higher than those before operation( P<0.05), with significant difference. The CRP level of ERAS group was lower than that of CPM group on the third day after operation, with significant difference ( P<0.05). On the 7th day after operation, the levels of Alb and PA in ERAS group were higher than those in CPM group ( P<0.05). The recovery time of gastrointestinal function and hospitalization days in ERAS group were significantly reduced, and the total cost of hospitalization was significantly less than that in CPM group ( P<0.05). Conclusions:Perioperative effective nutritional support is helpful to accelerate the recovery of patients with acute abdomen. The application of enhanced recovery after surgery can effectively improve the nutritional status of patients with acute abdomen, reduce the incidence of complications and improve the clinical outcome of patients.

Objective To analyze the epidemiological characteristics of hepatitis B in Guangzhou from 2006 to 2018. Methods The data were retrieved from the National Infectious Disease Surveillance Information Report Management System. Descriptive methods were used to analyze and summarize the results. Chi-square test was used for statistical analysis of classification data, and Joinpoint software was used to analyze the annual change percentage and trend. Results A total of 292 674 cases of hepatitis B were reported in Guangzhou from 2006 to 2018, and the annual average reported incidence was 182.2 per 100,000. Chronic hepatitis B was the main type, accounting for 89.9%. The incidence rate of males (241.6 / 105) was higher than that of females (117.9 / 105), with a ratio of 2.0:1. During the period from 2006-2018, the reported incidence of hepatitis B in Guangzhou first increased, reached the highest in 2008, and then decreased year by year. There was no significant difference in the number of HBV cases among different months. The average onset age of hepatitis B reported in Guangzhou was 39.3 years old, and the average onset age increased year by year from 2006 to 2018. Conclusion The incidence rate of hepatitis B in Guangzhou has decreased since 2008, but it was still higher than the national average incidence rate. The hepatitis B infection in Guangzhou remains a big issue. It is suggested to further strengthen the prevention and control of hepatitis B in adults by maintaining a national immunization program for children, thereby reducing the epidemiological level of hepatitis B in Guangzhou.
