		                        			Objective: To determine the feasibility of using temporary permanent pacemaker (TPPM) in patients with high-degree atrioventricular block (AVB) after transcatheter aortic valve replacement (TAVR) as bridging strategy to reduce avoidable permanent pacemaker implantation. Methods: This is a prospective observational study. Consecutive patients undergoing TAVR at Beijing Anzhen Hospital and the First Affiliated Hospital of Zhengzhou University from August 2021 to February 2022 were screened. Patients with high-degree AVB and TPPM were included. Patients were followed up for 4 weeks with pacemaker interrogation at every week. The endpoint was the success rate of TPPM removal and free from permanent pacemaker at 1 month after TPPM. The criteria of removing TPPM was no indication of permanent pacing and no pacing signal in 12 lead electrocardiogram (EGG) and 24 hours dynamic EGG, meanwhile the last pacemaker interrogation indicated that ventricular pacing rate was 0. Routinely follow-up ECG was extended to 6 months after removal of TPPM. Results: Ten patients met the inclusion criteria for TPPM, aged (77.0±11.1) years, wirh 7 females. There were 7 patients with third-degree AVB, 1 patient with second-degree AVB, 2 patients with first degree AVB with PR interval>240 ms and LBBB with QRS duration>150 ms. TPPM were applied on the 10 patients for (35±7) days. Among 8 patients with high-degree AVB, 3 recovered to sinus rhythm, and 3 recovered to sinus rhythm with bundle branch block. The other 2 patients with persistent third-degree AVB received permanent pacemaker implantation. For the 2 patients with first-degree AVB and LBBB, PR interval shortened to within 200 ms. TPPM was successfully removed in 8 patients (8/10) at 1 month without permanent pacemaker implantation, of which 2 patients recovered within 24 hours after TAVR and 6 patients recovered 24 hours later after TAVR. No aggravation of conduction block or permanent pacemaker indication were observed in 8 patients during follow-up at 6 months. No procedure-related adverse events occurred in all patients. Conclusion: TPPM is reliable and safe to provide certain buffer time to distinguish whether a permanent pacemaker is necessary in patients with high-degree conduction block after TAVR.

		                        			Objective  To analyze the correlation of hepatic steatosis with blood lipids and uric acid metabolism in elderly patients with chronic hepatitis B (CHB).  Methods The clinical data of 120 patients with CHB admitted to the hospital from January to December 2021 were retrospectively analyzed. According to the presence or absence of hepatic steatosis, the patients were divided into steatosis group (n=35) and non-steatosis group (n=85). The general clinical data, serological indicators of hepatitis B virus, blood lipid and uric acid levels were compared between the two groups. The correlation of hepatic steatosis grading with blood lipids and uric acid metabolism was analyzed.  Results  The inflammation and fibrosis degree of liver tissues were significantly different in the two groups (P<0.05). The levels of TG and TC in the steatosis group were higher than those in the non-steatosis group, and the level of HDL-C was lower than that in the non-steatosis group (P<0.05). There was no significant difference between the two groups in LDL-C and uric acid levels (P>0.05). Pearson correlation analysis found that the grade of hepatic steatosis in patients with CHB was negatively correlated with liver tissue inflammation, fibrosis degree and HDL-C level (P<0.05), and positively correlated with TG and TC levels (P<0.05).  Conclusion  Elderly patients with CHB and hepatic steatosis have abnormal blood lipid metabolism. Hepatic steatosis will exacerbate abnormal blood lipid metabolism but not liver tissue inflammation or fibrosis degree. Clinically, attention should be paid to blood lipid monitoring of elderly patients with CHB.

		                        			Objective: To investigate the incidence and treatment of perioperative anemia in patients with gastrointestinal neoplasms in Hubei Province. Methods: The clinicopathological data of 7 474 patients with gastrointestinal neoplasms in 62 hospitals in 15 cities (state) of Hubei Province in 2019 were collected in the form of network database. There were 4 749 males and 2 725 females. The median age of the patients was 62 years (range: 17 to 96 years). The hemoglobin value of the first time in hospital and the first day after operation was used as the criterion of preoperative anemia and postoperative anemia. Anemia was defined as male hemoglobin <120 g/L and female hemoglobin <110.0 g/L, mild anemia as 90 to normal, moderate anemia as 60 to <90 g/L, severe anemia as <60 g/L. The t test and χ2 test were used for inter-group comparison. Results: The overall incidence of preoperative anemia was 38.60%(2 885/7 474), and the incidences of mild anemia, moderate anemia and severe anemia were 25.09%(1 875/7 474), 11.37%(850/7 474) and 2.14%(160/7 474), respectively. The overall incidence of postoperative anemia was 61.40%(4 589/7 474). The incidence of mild anemia, moderate anemia and severe anemia were 48.73%(3 642/7 474), 12.20%(912/7 474) and 0.47%(35/7 474), respectively. The proportion of preoperative anemia patients receiving treatment was 26.86% (775/2 885), and the proportion of postoperative anemia patients receiving treatment was 14.93% (685/4 589). The proportions of preoperative anemia patients in grade ⅢA, grade ⅢB, and grade ⅡA hospitals receiving treatment were 26.12% (649/2 485), 32.32% (85/263), and 29.93% (41/137), and the proportions of postoperative anemia patients receiving treatment were 14.61% (592/4 052), 22.05% (73/331), and 9.71% (20/206). The proportion of intraoperative blood transfusion (16.74% (483/2 885) vs. 3.05% (140/4 589), χ²=434.555, P<0.01) and the incidence of postoperative complications (17.78% (513/2 885) vs. 14.08% (646/4 589), χ²=18.553, P<0.01) in the preoperative anemia group were higher than those in the non-anemia group, and the postoperative hospital stay in the preoperative anemia group was longer than that in the non-anemia group ((14.1±7.3) days vs. (13.3±6.2) days, t=5.202, P<0.01). Conclusions: The incidence of perioperative anemia in patients with gastrointestinal neoplasms is high. Preoperative anemia can increase the demand for intraoperative blood transfusion and affect the short-term prognosis of patients. At present, the concept of standardized treatment of perioperative anemia among gastrointestinal surgeons in Hubei Province needs to be improved.

		                        			Chronic unpredicted mild stress(CUMS) combined with isolated feeding was used to induce depressed rat model. The anti-depressant effects of Zhizichi Decoction(ZZCD) and its solid fermented product(ZZC) were analyzed by behavioral test and comparison of pathological tissues of hippocampus and liver, metabolic characteristics of intestinal flora, and relative abundance of species. The results showed that ZZC could increase sucrose preference, shorten the immobility time in the forced swim test and tail suspension test(P<0.05), and repair damaged hippocampus and liver tissues, and the effect was superior to that of ZZCD. The results of Biolog ECO plates showed that the average well color development(AWCD) of intestinal flora in the model group significantly decreased and the metabolic levels of sugar and amino acids were reduced, while the AWCD of the treatment groups increased. The metabolic levels of the two carbon sources were improved in the ZZC group, while only sugar metabolic level was elevated in the ZZCD group. Metagenomic analysis of intestinal flora showed that the ratio of Firmicutes/Bacteroidetes was 3.87 in the control group, 21.77 in the model group, 5.91 in the ZZC group, and 18.48 in the ZZCD group. Lactobacillus increased by 3.28 times, and Prevotella and Bacteroidetes decreased by 75.59% and 76.39%, respectively in the model group as compared with that in the control group. Lactobacillus decreased by 31.13%, and Prevotella and Bacteroidetes increased by more than three times in the ZZC group as compared with that in the model group, while the corresponding changes in the ZZCD group were not significant. ZZC could improve depression-like beha-viors by regulating the structure of intestinal flora and metabolic functions and repairing damaged hippocampus and liver tissues in depressed rats, showing an anti-depressant effect superior to that of ZZCD. This study is expected to provide a basis for the development of new anti-depressant food products.

		                        			OBJECTIVE:
		                        			To evaluate the clinical efficacy of local infiltration anesthesia of ropivacaine combined with compound betamethasone for postoperative analgesia in patients with hallux valgus.
		                        		
		                        			METHODS:
		                        			From September 2019 to December 2020, 48 patients with hallux valgus were treated surgically. According to different postoperative analgesia methods, the patients were divided into combined local infiltration group and intravenous analgesia pump group. There were 24 cases, in the combined local infiltration group including 2 males and 22 females;the age ranged from 21 to 78 years old, with an average of (58.3±7.7) years old;soft tissue release and chevron osteotomy were performed in 15 cases and metatarsophalangeal joint fusion in 9 cases;immediately after operation, 20 ml of ropivacaine combined with compound betamethasone mixed diluent was used for local infiltration anesthesia once. There were 24 patients in intravenous analgesia pump group, including 3 males and 21 females;the age ranged from 23 to 81 years old, with an average of(56.8±8.3) years old;soft tissue release and Chevron osteotomy were performed in 17 cases and metatarsophalangeal joint fusion in 7 cases;immediately after operation, intravenous analgesia pump was used for analgesia. The basic flow was 2 ml / h;the self control dose was 0.5 ml;and the locking time was 15 min. Visual analogue scale (VAS) was recorded at 12, 24, 48 and 72 hours after operation;and the VAS was recorded at 24 hours after operation. The occurrence of adverse drug reactions at 0 to 12 hours, 12 to 24 hours and 24 to 48 hours after operation were recorded;and the healing of incision was recorded.
		                        		
		                        			RESULTS:
		                        			All patients were followed up, and the duration ranged from 14 to 17 days, with a mean of (14.60±0.92) days. There was significantdifference in VAS at 12, 24 and 48 hours between the combined local infiltration group and the intravenous analgesia pump group(
		                        		
		                        			CONCLUSION
		                        			Compared with intravenous analgesia pump group, ropivacaine combined with compound betamethasone can significantly reduce postoperative wound pain without increasing adverse drug reactions, and does not increase wound infection.

		                        			Objective:
		                        			The relationship between serum uric acid (SUA) levels and glycemic indices, including plasma glucose (FPG), 2-hour postload glucose (2h-PG), and glycated hemoglobin (HbA1c), remains inconclusive. We aimed to explore the associations between glycemic indices and SUA levels in the general Chinese population.
		                        		
		                        			Methods:
		                        			The current study was a cross-sectional analysis using the first follow-up survey data from The China Cardiometabolic Disease and Cancer Cohort Study. A total of 105,922 community-dwelling adults aged ≥ 40 years underwent the oral glucose tolerance test and uric acid assessment. The nonlinear relationships between glycemic indices and SUA levels were explored using generalized additive models.
		                        		
		                        			Results:
		                        			A total of 30,941 men and 62,361 women were eligible for the current analysis. Generalized additive models verified the inverted U-shaped association between glycemic indices and SUA levels, but with different inflection points in men and women. The thresholds for FPG, 2h-PG, and HbA1c for men and women were 6.5/8.0 mmol/L, 11.0/14.0 mmol/L, and 6.1/6.5, respectively (SUA levels increased with increasing glycemic indices before the inflection points and then eventually decreased with further increases in the glycemic indices).
		                        		
		                        			Conclusion
		                        			An inverted U-shaped association was observed between major glycemic indices and uric acid levels in both sexes, while the inflection points were reached earlier in men than in women.
