		                        			OBJECTIVE To investigate the effects of GSTP1, XRCC1, ABCB1, MTHFR gene polymorphisms on efficacy and toxic effect of chemotherapy regimen containing oxaliplatin in patients with stage Ⅲ and Ⅳ colorectal cancer patients. METHODS Clinical data of 76 patients with stage Ⅲ and Ⅳ colorectal cancer who received chemotherapy regimen containing oxaliplatin (XELOX,FOLFOX) were collected from the Second Affiliated Hospital of Soochow University from September 2018 to March 2020. The correlation of genotypes with progression-free survival (PFS) and toxic effect was analyzed by using univariate and multivariate COX regression model. RESULTS Carriers of the ABCB1 3435T>C locus C allele (TC/CC) had a significantly higher risk of progression compared to TT genotype patients [HR=2.39, 95%CI (1.05,5.50), P=0.038]. The risk of progression in patients at stage Ⅳ was significantly higher than those at stage Ⅲ [HR=8.11, 95%CI(3.39,19.40), P<0.001]. Chemotherapy regimen, Karnofsky performance status score and tumor site had no significant effect on disease progression (P>0.05). Mutations in gene loci were not correlated with adverse reactions (P>0.05). CONCLUSIONS Patients carrying ABCB1 TC/CC and receiving chemotherapy regimen containing oxaliplatin have a higher risk of disease progression, which may be associated with longer PFS in patients (TT genotype) with stage Ⅳ colorectal cancer receiving the chemotherapy, while GSTP1, XRCC1, and MTHFR gene polymorphisms have no significant impact.

		                        			Objective:To investigate the efficacy and safety of kidney sparing treatment based on Thulium laser ablation and systematic therapy in localized high-risk upper urinary tract urothelial carcinoma (UTUC).Methods:The data of 10 patients with UTUC who received combined treatment based on Thulium laser and systematic treatment from January 2020 to December 2021 in West China Hospital were retrospectively analysed. There were 5 males and 5 females with a median age of 76 (range 52 to 87)years old. Three cases were renal pelvis tumor and 7 cases were ureter tumor including 5 cases in lower ureter and 2 cases in upper and middle ureter. Five cases were with positive urine cytology and 6 cases were with hydronephrosis. One case was muscular invasion UTUC confirmed by biopsy(cT 2+), 7 cases were high-grade invasive urothelial carcinoma (cT 1+), and 2 cases were high-grade papillary urothelial carcinoma (cT a). Among 10 cases, 5 patients refused radical nephroureterectomy(RUN), among whom 3 patients were too old or in poor general condition to tolerate RNU. One case had a solitary kidney and 1 case had bilateral tumours. Patients were treated with Thulium laser tumor ablation under ureteroscopy combined with systemic therapy. The perioperative systemic treatment included platinum-based chemotherapy±immunotherapy, RC48+ immunotherapy, and immunotherapy alone. The postoperative treatment was immunotherapy maintenance±local radiotherapy. Strict follow-up was conducted after the completion of treatment. Results:Nine patients received systemic therapy before ablation. Four cycles of platinum-based chemotherapy (cisplatin in 2 cases, carboplatin in 1 case) were used in 3 cases, and platinum-based chemotherapy + immunotherapy (6 cycles of cisplatin + toripalimab in 1 case, 4 cycles of cisplatin + toripalimab in 1 case, 4 cycles of carboplatin+ trelizumab in 1 case) was used in 3 cases, four cycle of RC48 + immunotherapy (toripalimab or trelizumab) were used in 2 cases, and four cycles of immunotherapy (toripalimab) were used in 1 case. The operations of 10 cases were successfully completed without serious complications during the perioperative period and the laser working time (42.4 ± 15.2) min. Of the 10 cases, 4 achieved complete ablation at the first ablation, and 6 patients had incomplete ablation. Among them, 2 patients achieved clinical complete remission after 1-2 cycles of systemic therapy, and 4 patients achieved complete ablation after Thulium laser ablation again.All the 10 patients were treated with immunotherapy for 1 year, and 2 of them received additional adjuvant radiotherapy. The patients were followed-up for median 40 months(range 26 to 53 months). Recurrence occurred in 5 cases, of which 3 cases underwent salvage nephroureterectomy and 2 cases underwent Thulium laser ablation under ureteroscopy again. Five patients had no tumor recurrence. None of the 10 patients had distant metastasis. At the last follow-up, 1 patient died of complications and 6 patients kept the affected kidney alive. Perioperative complications including macroscopic hematuria (8 cases), fever (3 cases), the long-term complications of ureter stenosis (4 cases).Conclusions:For localized high-risk UTUC, local Thulium laser ablation combined with systemic therapy can achieve good tumor control while preserving the affected kidney in selected patients, and its potential application value should be further evaluated.

		                        			Objective: To characterize the incidence density of systematic lupus erythematosus (SLE) in Yinzhou District of Ningbo from 2016 to 2021, and compare the age and gender specific differences. Methods: A retrospective cohort study was conducted based on the related data from 2015 to 2021 collected from the Health Information Platform of Yinzhou. Suspected SLE cases in local residents were identified by fuzzy matching of International Classification of Diseases 10th edition code "M32" or Chinese text "lupus". The classification criteria from Systemic Lupus International Collaboration Clinics-2012 and The European League Against Rheumatism/American College of Rheumatology-2019 were used for case verification. SLE cases were identified with specific algorithm based on verification results, and new cases were identified with 1 year as the washout period. The incidence density and 95%CI were estimated by Poisson distribution. Results: From 2016 to 2021, a total of 1 551 921 permanent residents were registered in Yinzhou, in whom 51.52% were women. The M(Q1,Q3) age at enrollment was 40.38 (27.54, 53.54) years. The M(Q1,Q3) of follow-up person-years was 3.83 (0.41, 5.83) years. There were 451 new SLE cases, in which 352 were women (78.05%). The 6-year incidence density was 8.14/100 000 person-years (95%CI: 7.41/100 000 person-years-8.93/100 000 person-years) for the total population, 3.68/100 000 person-years (95%CI: 2.99/100 000 person-years-4.48/100 000 person-years) for men and 12.37/100 000 person-years (95%CI: 11.11/100 000 person-years- 13.73/100 000 person-years) for women. The incidence density in men appeared a small peak at 20-29 years old, and began to increase with age from 40 years old. The incidence density in women was highest in age group 20-29 years (16.57/100 000 person-years) and remained to be high until 30-79 years old. The incidence density of SLE in Yinzhou show no significant temporal trend from 2016 to 2021 (men: P=0.848; women: P=1.000). Conclusions: The incidence density of SLE in Yinzhou from 2016 to 2021 was similar to those of other areas in China. SLE has a high incidence in women, especially in the young and elderly, suggesting that more attention should be paid to the diagnosis and treatment of SLE in women.

		                        			Objective:To evaluate the influence of cytomegalovirus (CMV) infection on T cell senescence and cardiovascular disease (CVD) in maintenance hemodialysis (MHD) patients.Methods:It was a single center cross sectional study. Patients aged over 18 years old and received hemodialysis for at least 6 months at the Blood Purification Centre of the Department of Nephrology of Zhongshan Hospital Affiliated to Fudan University from January 2021 to April 2021 were enrolled. Demographic, hematological, nutritional and inflammatory markers were obtained. Anti-CMV-IgM and IgG antibodies were detected using the Roche Elecsys assay. CD28 - T cell was evaluated by flow cytometry. Mann-Whitney U test or Kruskal-Wallis H test was used for anti-CMV-IgG comparison among groups. Spearman correlation and linear regression were used to assess the relationship between anti-CMV-IgG and CD28 - T cell compartment. Logistic regression was used to assess the relationship between anti-CMV-IgG and CVD. Results:A total of 438 MHD patients (270 men and 168 women) were enrolled in the study. The median age was 62 (51, 70) years. The median time on hemodialysis was 57 (21, 100) months. The primary diseases included chronic glomerulonephritis [213 cases (48.6%)], diabetic nephropathy [82 cases (18.7%)], polycystic kidney disease [34 cases (7.8%)], hypertensive renal disease [34 cases (7.8%)], etc. Of these patients, 430 (98.2%) were seropositive for anti-CMV-IgG, 206 (47.0%) had anti-CMV-IgG titers exceeding the upper limit of 500 U/ml. Patients aged over 70 years old were 100% seropositive for anti-CMV-IgG. Patients on HD for more than 5 years had a higher seropositive rate of 99.1% than those with shorter HD duration, although these results were not statistically significant. Spearman correlation analysis showed that the anti-CMV-IgG titers in MHD patients were positively correlated with the proportion of CD4 + CD28 - T cells and CD8 + CD28 - T cells ( r=0.316, P<0.001; r=0.272, P<0.001). Multiple linear regression analysis showed that after adjusting for age and gender, lg[CD4 + CD28 - T cells(%)] and lg[CD8 + CD28 - T cells(%)] were positively correlated with lg[anti-CMV-IgG titers (U/ml)], respectively ( β=0.455, t=8.315, P<0.001; β=0.412, t=7.282, P<0.001). In analyzing the relationship between anti-CMV-IgG titers and CVD, patients were divided into six groups according to age and anti-CMV-IgG level. Group 1 included young patients with a lower anti-CMV-IgG titers (age ≤55 years old, anti-CMV-IgG <400 U/ml); Group 2 included young patients with a higher anti-CMV-IgG titers (age≤55 years old, anti-CMV-IgG ≥400 U/ml); Group 3 included middle-aged patients with a lower anti-CMV-IgG titers (55

		                        			Objective: To externally validate and compare the accuracy of the China-PAR (Prediction for ASCVD Risk in China) model and the 2019 World Health Organization (WHO) cardiovascular disease risk charts for East Asian in predicting a 10-year cardiovascular disease in a general Chinese population. Methods: Participants aged 40-79 years without prior cardiovascular disease at baseline in the CHinese Electronic health Records Research in Yinzhou (CHERRY) were analyzed. The Kaplan-Meier analysis estimated the observed cardiovascular events (including non-fatal myocardial infarction, fatal coronary heart disease, and non-fatal or fatal stroke) rate within ten years. The expected risks were calculated using the WHO risk charts for East Asia (including the laboratory-based and non-laboratory-based models) and the China-PAR model. The expected-observed ratios were calculated to evaluate the overestimation or underestimation of the models in the cohort. Model accuracy was assessed by discrimination C-index, calibration χ2 value, and calibration plots. Results: During a median of 7.26 years of follow-up, 13 301 cardiovascular events were identified among 225 811 participants. The C-index for the China-PAR model, WHO laboratory-based model and WHO non-laboratory-based model were 0.741 (0.735-0.747), 0.747 (0.740-0.753), and 0.739 (0.733-0.746) for men, and 0.782 (0.776-0.788), 0.789 (0.783-0.795), and 0.782 (0.776-0.787) for women, respectively. The WHO laboratory-based model and non-laboratory-based model underestimated the 10-year ASCVD risk by around 15% in women and underestimated by 0.8% and 4.4% in men, respectively. The China-PAR model underestimated the risks by 19.5% and 42.3% for men and women. Conclusions: The China-PAR and WHO models all have pretty good discriminations for 10-year cardiovascular risk assessment in this general Chinese population. However, the accuracy should be improved in the highest-risk groups, suggesting further specific models are still needed for those with the highest risk, such as patients with diabetes or older persons.

		                        			Objective: To describe the distribution and trend of rheumatoid arthritis (RA) in adults in the Yinzhou district from 2011 to 2020 and compare the incidence differences in different ages and genders. Methods: Using the retrospective cohort design, we collected all new cases diagnosed with RA between 2011 to 2020 from the Yinzhou Regional Health Information Platform (YRHIP). Poisson distribution was used to estimate RA's incidence density and 95%CI. Results: From 2011 to 2020, 1 280 012 permanent residents in Yinzhou district were included, of which 665 361 were female (51.98%). The total follow-up person-years were 7 198 513.61, and the median follow-up person-year was 5.41 years (P25=3.50, P75=8.32). During the study period, there were 2 350 new cases of RA, of which 1 460 were female (62.13%). The 10-year incidence density of the population was 32.65/100 000 person-years (95%CI: 31.34/100 000 person-years-33.99/100 000 person-years), that of females was 39.17/100 000 person-years (95%CI: 37.19/100 000 person-years-41.24/100 000 person-years), and that of the male was 25.64/100 000 person-years (95%CI: 23.98/100 000 person-years-27.38/100 000 person-years), the gender difference was statistically significant (P<0.001). The incidence risk in all age groups above 30 years old was higher than that in the 18-29 years old group (P<0.001), and the incidence risk increased with age from 18-79 years old while decreased slightly with age ≥80 years old. The lowest incidence density was 15.30/100 000 person-years in 2013 (95%CI:12.62/100 000 person-years-18.38/100 000 person- years), and the highest was 56.70/100 000 person-years in 2016 (95%CI: 51.24/100 000 person- years - 62.58/100 000 person-years), with statistically significant differences among different years (P=0.004). Conclusions: From 2011 to 2020, the incidence density of RA in adults in Yinzhou district first increased, then decreased, and tended to stabilize. There were differences in incidence density in different years, ages, and genders.

		                        			Objective: To explore the promotion effect of laparoscopic standardized surgery for gastric cancer observational in some regional medical centers in Shanghai. Methods: A retrospective cohort study was carried out. Eleven regional medical centers in Shanghai received the promotion program of laparoscopic standardized surgery for gastric cancer, which was led by Ruijin Hospital, Shanghai Jiaotong University School of Medicine (Shanghai Minimally Invasive Surgery Center) from January to December 2020. Clinicopathological data of gastric cancer patients treated at these 11 regional medical centers before and after the promotion program were collected. Inclusion criteria were as follows: patients undergoing laparoscopic distal gastrectomy or total gastrectomy; gastric cancer confirmed by pathology; without distant metastasis or peritoneal metastasis. Patients who did not undergo laparoscopic D2 radical resection, or received neoadjuvant chemotherapy before surgery, or without complete clinical data were excluded. Patients undergoing laparoscopic surgery from January to December 2019 were included in the pre-promotion group (46 cases). Patients undergoing laparoscopic surgery from January to December 2021 were included in the post-promotion group (102 cases). In addition, patients undergoing laparoscopic surgery at Ruijin Hospital from January 2021 to December were included in the control group (138 cases). The baseline data, perioperative measurements postoperative complications, and pathological results of the three groups were analyzed and compared. Results: There were no significant differences in baseline characteristics among the three groups (all P>0.05). Compared with the pre-promotion group, the operation time in post-promotion group was significantly shorter [(207.3±36.0) minutes vs. (254.2±47.1) minutes, t=7.038,P<0.001], and the number of harvested lymph node was significantly more (24.4±12.2 vs. 18.9±5.5, t=2.900, P=0.004). However, there were no significant differences in the extent of resection, time to fluid intake, and postoperative hospital stay between the two groups (all P>0.05). Compared with the control group, the operation time [(207.3±36.0) minutes vs (172.6±26.0) minutes, t=8.281, P<0.001], time to fluid intake [(6.3±3.2) days than (5.5±3.0) days, t=2.029, P=0.044], and the postoperative hospital stay [(14.3±5.6) days vs. (10.1±4.8) days, t=6.036, P<0.001] in the post- promotion group were still longer. Total gastrectomy was less common in the post-promotion group compared with the control group [18 cases (17.6%) vs. 41 cases (29.7%), χ2=7.380, P=0.007]. However, there was no significant difference in the number of harvested lymph node between the two groups (P>0.05). The morbidity of postoperative complication in the post-promotion group (9.8%, 10/102) was significantly lower than that in the pre-promotion group (23.9%, 11/46) (χ2=5.183, P=0.023), while above morbidity was not significantly different between the post-promotion group and the control group [9.8% vs. 6.5% (9/138), χ2=0.867, P=0.352]. Conclusion: After the promotion of laparoscopic standardized surgery for gastric cancer in regional medical centers, the standardization degree of surgery has been improved, and the morbidity of postoperative complication decreases. Laparoscopic standardized surgery for gastric cancer can be promoted to more regional medical centers.

		                        			OBJECTIVE:
		                        			To describe the distribution characteristics of inflammatory bowel disease among permanent residents in Yinzhou District, Ningbo City, and to understand the disease burden and development trend of inflammatory bowel disease in this area.
		                        		
		                        			METHODS:
		                        			Using the retrospective cohort design, we collected the registration information of all permanent residents in the residents' health files of the Yinzhou Regional Health Information Platform from 2010 to 2020, and used electronic medical records to follow up their inflammatory bowel disease visits. A one-year wash-out period was set, and the patients who were diagnosed with the primary diagnosis for the first time after one year of registration were re-garded as new cases. The incidence density and 95% confidence interval (CI) of inflammatory bowel disease were estimated by Poisson distribution.
		                        		
		                        			RESULTS:
		                        			From 2011 to 2020, a total of 1 496 427 permanent residents in Yinzhou District were included, of which 729 996 were male (48.78%). The total follow-up person-years were 8 081 030.82, and the median follow-up person-years were 5.41 [interquartile range (IQR): 5.29]. During the study period, there were 1 217 new cases of inflammatory bowel disease, of which males (624 cases, 51.27%) were more than females (593 cases, 48.73%). The total incidence density was 15.06/100 000 person-years (95%CI: 14.23, 15.93). Among all new cases, there were 1 106 cases (90.88%) of ulcerative colitis, with an incidence density of 13.69 per 100 000 person-years (95%CI: 12.89, 14.52); 70 cases (5.75%) of Crohn's disease, with an incidence density of 0.87 per 100 000 person-years (95%CI: 0.68, 1.09); and 41 cases (3.37%) of indeterminate colitis, with an incidence density of 0.51 per 100 000 person-years (95%CI: 0.36, 0.69). The median age of onset of ulcerative colitis was 50.82 years old (IQR: 18.77), with the highest proportion (15.01%) in the 45-49 years group. The incidence density of ulcerative colitis gradually increased with age, reaching a relatively high level in the 45-49 years group (20.53/100 000 person-years; 95%CI: 17.63, 23.78), followed by a slight increase. And the incidence density in the 65-69 years group was the highest (25.44/100 000 person-years; 95%CI: 20.85, 30.75), with a rapid decrease in the 75-79 years group. The median age of onset of Crohn's disease was 44.34 years (IQR: 33.41), with the highest proportion (12.86%) in the 25-29 years group. Due to the small number of new cases of Crohn's disease, the age distribution fluctuated greatly, with peaks both in young and old people. From 2011 to 2020, the incidence density of inflammatory bowel disease in Yinzhou District was at a low level from 2011 to 2013, and showed a rapid upward trend from 2014 to 2016, reaching a peak of 24.62 per 100 000 person-years in 2016 (95%CI: 21.31, 28.30), and slightly decreased in 2017-2020.
		                        		
		                        			CONCLUSION
		                        			The incidence density of inflammatory bowel disease in Yinzhou District from 2011 to 2020 was at a relatively high level, and medical institutions and health departments need to pay attention to the burden of disease caused by it.

		                        			Objective: To understand the hospitalization rates and influencing factors after diagnosis among HIV infection cases, based on real-world data in Yinzhou district of Ningbo. Methods: A retrospective cohort study was conducted based on the databases of National AIDS Comprehensive Response Information Management System and Yinzhou Health Information Platform. The information about the following-up results, antiviral treatment data, electronic records of inpatient of the HIV cases reported during 2012-2020 were collected to analyze the rates, causes and influencing factors of hospitalization. Results: Among the 763 HIV infection cases reported in Yinzhou from 2012 to 2020, the hospitalization rate was 6.95% (53/763), and the number of inpatient was 2.59 per 100 person years. The hospitalization rate and the number of hospitalization per 100 person years in HIV infection cases were 3.16% (10/316) and 0.81 in those aged <30 years, 6.07% (15/247) and 1.59 in those aged >30 years, 7.86% (11/140) and 4.05 in those aged >45 years and 28.33% (17/60) and 17.40 in those aged ≥60 years respectively. Logistic multivariate regression analysis indicated that being aged ≥60 years was the influencing factor for hospitalizations in HIV infection cases (аOR=14.44, 95%CI:3.57-58.46). The hospitalization rates due to AIDS related diseases, cardiovascular diseases and metabolic diseases, and other diseases were 1.83% (14/763), 1.05% (8/763), and 3.93% (30/763), respectively. Conclusions: The hospitalization burden due to HIV infection was still mainly caused by those aged ≥60 years in Yinzhou, similar to that in general population and less proportion of hospitalizations were due to AIDS related diseases. The overall increase of hospitalizations due to AIDS was not obvious in Yinzhou.
