Objective To investigate the timing of endoscopic therapy of obstructive acute biliary pancreatitis. Methods One hundred and sixty cases of obstructive acute biliary pancreatitis treated by endoscopy were analyzed. The patients were divided into two groups:78 cases received emergency endoscopic therapy (EE group) within 48 hours from onset of symptoms,including endoscopic retrograde cholangiopan-creatography and endoscopic sphincterotomy,with or without stone extraction and endoscopic nasobiliary drainage;82 cases received delay endoscopic therapy (DE group) after initial 48 hours of conservative management Results The total success rate of therapeutic endoscopy was 96.2 % (154/160). In EE group, the time for disappearance of abdominal pain [(4.98±1.75)d],the time for laboratory recovery [(10.08± 5.22) d],and the length of hospitalization [(12.24 ± 7.20) d] were significantly shorter than those in DE group [(5.54±2.53),(12.93 ±6.60),(16.38 ±6.94) d](P<0.05 or <0.01). In cases with severe acute biliary pancreatitis,the morbidity in the EE group (9.6% ,5/52) was significantly lower than DE group (23.6%,13/55) (P<0.05),but the difference in mortality rate between the two groups was not significant (P>0.05). Conclusions In severe acute biliary pancreatitis patients with biliary tract obstruction, emergency endoscopic therapy should be performed within 48 hours from the onset of symptoms. Patients with mild acute biliary pancreatitis should also undergo prompt endoscopic therapy after ineffective conservative management or appearance of symptoms of acute biliary tract infection.

Objective To compare postoperative outcomes and complications between subtotal colectomy combined with modified Duhamel procedure and simple subtotal colectomy for severe functional constipation (SFC). Methods Between January 2006 and June 2010,40 SFC patients after strict but inefficient nonoperative treatments were randomized by number table method to control group (20 cases, receiving simple subtotal colectomy) and combined group (20 cases,receiving subtotal colectomy and modified Duhamel procedure). The selection criteria were normal colonoscopy,and abnormal dynamic proctography (DPG). The functional outcomes after surgery were assessed from 6 months to 2 years period. Results The preoperative clinical manifestations of the two groups were similar. No statistically significant difference was observed between the two groups for time for recovery of the bowel function,length of postoperative hospitalization.and the early postoperative complications (P > 0.05). Functional outcomes of combined group with CIQOL score [(110.5 ±5.0) scores],relieving of costive gastrointestinal symptoms [(79.0 ±6.5)%], recurrent constipation rate [10.0% (2/20)], satisfaction rate of defecation frequency [85.0%(17/20)], satisfaction rate of quality of life[90.0%(18/20)] were significantly better than those of control group[(90.5 ± 3.5) scores, (60.5 ± 2.8)% ,35.0%(7/20), 15.0%(3/20),20.0%(4/20)](P< 0.05). Conclusion Combined application of subtotal colectomy and modified Duhamel procedure for SFC has better outcomes.

Objective: The survival of colorectal cancer in Qidong City, Jiangsu Province from 1972 to 2016 was analyzed to provide a basis for the evaluation of prognosis and the formulation of prevention and control measures. Methods: Colorectal cancer data were obtained from the Qidong Cancer Registration and Reporting System, and the follow-up was up to December 31, 2021. The observed survival rate (OSR) and relative survival rate (RSR) were calculated by SURV 3.01 software, and the trend test was performed by Hakulinen's likelihood ratio test. The Joinpoint regression model was used to calculate the average annual percentage change (AAPC) of survival, and the ARIMA model was used to predict the trend of colorectal cancer survival. Results: There were 8 637 new cases of colorectal cancer in Qidong from 1972 to 2016. Dividing 1972-2016 into 9 periods at 5-year intervals, the 5-year OSR from 1972-1976 to 2012-2016 increased from 21.86% to 48.86%, and the 5-year RSR increased from 26.45% to 59.91%. The increasing trend of RSR was statistically significant (χ(2)=587.47, P<0.001). From 1972 to 2016, the survival rates of colorectal cancer in different sexes in Qidong were similar, and the 5-year RSR was 44.63% for men and 44.07% for women. Since the 1990s, the 5-year OSR and RSR for men have been lower than those for women. From 1972 to 2016, the 5-year RSR of colorectal cancer in Qidong was significantly improved in the 65-74 and ≥75-year-old groups, but the survival rate of the ≥75-year-old group was still the lowest (36.78%), followed by the 35-44-year-old group ( 43.04%). The time trend showed that the overall AAPC of colorectal cancer 5-year RSR in Qidong from 1972 to 2016 was 2.50% (t=16.45, P<0.001). The upward trend of different sexes was consistent, and the increase was greater in women (AAPC for males=2.18%, AAPC for females=2.54%, both P<0.05). The 5-year RSR of colorectal cancer in each age group showed an upward trend, and the AAPCs of the 35-44, 45-54, 55-64, 65-74, and ≥75-year-old groups were 1.54%, 1.83%, 2.00%, 3.51% and 4.35%, respectively (all P<0.05). The prediction results of colorectal cancer survival rate showed that the 5-year RSR of colorectal cancer in Qidong will increase to 71.62% by 2026. Conclusions: The overall survival rate of colorectal cancer patients in Qidong has been greatly improved, but there is still room for improvement. We should continue to pay attention to the early diagnosis and early treatment of colorectal cancer.

Objective: To evaluate the patients′ survival and effectiveness of the live cancer screening for population at high risk for liver cancer in Qidong. Methods: According to the Expert Scheme proposed the Expert Committee of Early Detection and Early Treatment, China Cancer Foundation, diagnostical screening by using combined methods of alpha-fetoprotein and B ultrasound monitoring were carried out biannually in individuals with positive HBsAg who were screened from Qidong area. The evaluation indices of the effectiveness are task completion rate of screening, detection rate of liver cancer, early diagnosis rate, and treatment rate. The deadline of the follow-up for the surviving outcome was March 31, 2016. The life-table method was used to calculate the observed survival, and to make comparison and significant tests between survival rates in Group A (those found via repeated periodic screening) and Group B (those diagnosed without periodic screening). Results: Since 2007, 38 016 target population have been screened, and 3 703(9.74%) individuals with positive HBsAg were found. Except for 29 patients with liver cancer at the initial screening, 3 674 persons in the cohort were followed up; 268 patients with liver cancer were detected from the 33 199 person-times screening, with an annual detection rate of 1.61%. Of them, 186 patients were found in Group A(1.12%), in which 149 patients were the early cases, with an early detection rate of 80.11%; 167 out of 186(89.78%) patients received treatment after diagnosis. The incidence of liver cancer in this HBsAg (+ ) cohort of 25 452 person-years was 1 052.96 per 100 000 annually, 187 cases in males(1 488.45/100 000)and 81 cases in females(628.46/100 000). The 1-, 3-, 5-, and 8-year survival of all patients with liver cancer were 64.55%, 40.50%, 32.54%, and 19.65%, respectively. The 1-, 3-, 5-, and 8-year survival rates were 77.16%, 49.04%, 38.53%, and 24.25% in Group A, and were 36.25%, 21.21%, 21.21%, and 0% in Group B, respectively, with significant differences between two groups (P<0.05). Conclusion The findings show that screening of individuals at high-risk of development of liver cancer, with semiannual AFP and B ultrasound, according to the Expert Scheme, is effective not only in increasing detection rate but also in detecting liver cancer at early stage, and in improving patients′ survival as well.

Objective: To describe the epidemic characteristics of stomach cancer mortality in Qidong between 1972 and 2016. Methods: The cancer registry data of stomach cancer death and population during 1972-2016 in Qidong was collected. The mortality of crude rate (CR), China age-standardized rate (CASR), world age-standardized rate (WASR), 35-64 years truncated rate, 0-74 years cumulative rate, cumulative risk, percentage change (PC), annual percent change (APC) were calculated. Results: During 1972-2016, a total of 15 863 (male: 10 114, female: 5 749) deaths occurred attributed to stomach cancer, accounting for 16.04% of all cancers, with CR of 31.37/100 000 (CASR: 12.97/100 000, WASR: 21.39/100 000). The truncated rate of 35-64, cumulative rate of 0-74, and cumulative risk were 28.86/100 000, 2.54%, and 2.51%, respectively. For male, the CR, CASR, WASR were 40.53/100 000, 17.98/100 000, 30.13/100 000, respectively, and for female, the CR, CASR, WASR were 22.45/100 000, 8.52/100 000, 13.92/100 000, respectively. Age-specific mortality analysis showed that the mortality of each age group under 25-year-old group was less than 1/100 000. The CR increased with age. The 50-year-old group reached and exceeded the average mortality of the population, and more than 80-year-old group reached the peak of death. During 1972-2016 in Qidong, The PCs in CR, CASR, and WASR of stomach cancer were 55.43%, -52.02%, -43.60%. The APC were 0.54%, -2.30%, -2.08%, respectively. Period mortality analysis showed that except for the 75-year-old group, the mortality of stomach cancer decreased significantly. Conclusions: The crude mortality of stomach cancer increases slightly in Qidong, while the CASR and WASR decrease significantly. However, stomach cancer is still one of the malignant tumors that most affect health and seriously threat lives.

Objective: To analyze the survival of esophageal cancer cases in Qidong, Jiangsu Province from 1972 to 2016, and provide a basis for the prognosis evaluation and prevention of esophageal cancer patients. Methods: The data of esophageal cancer were obtained from the Qidong Cancer Registration and Reporting System, and the follow-up date ended December 31, 2021. Observed survival rate (OSR) and relative survival rate (RSR) were calculated by SURV 3.01 software, and Hakulinen's likelihood ratio test was used for statistical difference comparison. Joinpoint regression model was used to conduct the average annual percentage change (AAPC) in esophageal cancer survival rate, and the ARIMA model was used to predict the trend of esophageal cancer survival rate. Results: During 1972 to 2016, there were 5 112 new cases of esophageal cancer in Qidong. The OSR of esophageal cancer at 1, 5 and 10 years were 24.43%, 6.93% and 4.43%, and the RSR at 1, 5 and 10 years were 25.88%, 9.35% and 8.34%, respectively. Dividing 1972-2016 into 9 periods, compared with 1972-1976, the 5-year RSR from 2012-2016 increased from 4.47% to 17.85%, and the RSR trend of the 9 periods was statistically significant (χ(2)=263.43, P<0.001). The survival rate of female with esophageal cancer was slightly higher than that of male, however, there was no significant difference in RSR between male and female (χ(2)=9.40, P=0.401). The 5-OSR and 5-RSR for male were 6.73% and 9.11%, and for female were 7.37% and 9.87%, respectively. The 5-RSR for the age groups of 45-54, 55-64, 65-74, and over 75 years old were 11.99%, 11.21%, 8.17% and 7.08%, respectively. There was a statistically significant difference in RSR among different age groups (χ(2)=98.19, P<0.001). The time trend results showed that the overall AAPC of the 5-RSR of esophageal cancer in Qidong from 1972 to 2016 was 3.89% (t=11.98, P<0.001). The 5-RSR uptrend was consistent among different genders, and the uptrend was greater in female (AAPC=4.25% for male, and AAPC=5.72% for female, P<0.05). Furthermore, the 5-RSR of esophageal cancer in all age groups showed an upward trend, and the upward trend was statistically significant in the 55-64-year-old group (AAPC=4.23%, P<0.05) and the 65-74-year-old group (AAPC=6.82%, P<0.05), there was no statistical significance in the 45-54-year-old group (AAPC=2.17%, P>0.05) and more than 75 years old group (AAPC=1.82%, P>0.05). Survival rate prediction of esophageal cancer showed that by 2026, 5-RSR will increase to 24.79%. Conclusions: During 1972 to 2016, the overall survival rate of esophageal cancer in the whole population of Qidong has improved to a certain extent, but there is still a large room for improvement. More emphasis should be continued to strengthen on the early diagnosis and early treatment of esophageal cancer.

Objective: The survival rate of gastric cancer cases in the whole population of Qidong City of Jiangsu Province from 1972 to 2016 was analyzed to provide a data basis for prevention and control of gastric cancer. Methods: The observed survival rate (OSR) was calculated by the life table method, the relative survival rate (RSR) was calculated by SURV 3.01 software, and the trend test was performed by Hakulinen's likelihood ratio test. Age-standardized relative survival rate (ARSR) was calculated using the International Cancer Survival Standard (ICSS). The Joinpoint regression model was used to calculate the average annual percentage change (AAPC) of survival rate, and the trend analysis of the overall survival rate of gastric cancer and the survival rates of different sexes and ages was conducted. The ARIMA model was used to predict the survival rate. Results: From 1972 to 2016, there were 18 067 new cases of gastric cancer in Qidong City. The OSRs at 1, 5, and 10 years were 37.12%, 17.16%, and 12.86%, respectively, and the RSRs at 1, 5, and 10 years were 38.83%, 21.73%, and 21.20%. Dividing 1972-2016 into 9 periods at 5-year intervals, compared with 1972-1976, the 5-year RSR in 2012-2016 increased from 12.53% to 36.26%, and the RSR in the 9 periods increased with statistical significance (χ(2)=747.19, P<0.001). Both OSR and RSR were slightly higher in men than in women, and decreased with age. The AAPC results showed that the AAPC of the 5-year RSR of gastric cancer in Qidong was 2.88%, 2.75% in males and 3.05% in females, and the upward trend was statistically significant (P<0.001). From 1972 to 2016, the 5-year RSR of gastric cancer in all age groups showed an upward trend. Except for the 35-44-year-old group (AAPC=1.07%, t=2.16, P=0.067), the age groups had statistical significance ( AAPC=2.59% in the 45-54-year-old group, AAPC=3.19% in the AAPCs of other 55-64-year-old group, AAPC=3.99% in the 65-74-year-old group, and AAPC=2.97% in the 75-year-old group, all P<0.05). The prediction results of the ARIMA model showed that in 2026, the 5-year OSR of gastric cancer in Qidong will increase to 39.82%, and the 5-year RSR will increase to 49.23%. Conclusion: The overall survival rate of registered gastric cancer cases in Qidong has been greatly improved, but there is still large room for improvement. More attention should be paid to the prevention and treatment of gastric cancer.

[Objective]To assess the difference of resurfacing versus nonresurfacing the patella in total knee arthroplasty. [Methods]Studies on comparison between resurfacing and nonresurfacing the patella in total knee arthroplasty were identified.All the randomized controlled trials were included for Meta analysis with Rev Man 4.2 software.[Results]Sixteen eligible randomized controlled trials showed 1922 TKA.The result of meta-analysis indicated that the risk of postoperative anterior knee pain was lower in patellar resurfacing group than in patellar nonresurfacing group within 5 years.But the difference did not exist after 5 years.The combined RR was 0.53,95%CI(0.30,0.94).The risk of reoperation had no significant difference in patellar resurfacing group and patellar nonresurfacing group within 5 years.But 5 years later,the risk of reoperation was lower in patellar resurfacing group than in patellar nonresurfacing group.The combined RR was 0.35,95%CI(0.18,0.66).There was no difference in the mean postoperative knee scores(WMD=0.44,95%CI(-1.22,2.09)).[Conclusion]Patellar resurfacing can reduce the risk of postoperative anterior knee pain within 5 years and the risk of reoperation 5 years later after total knee arthroplasty.There is no difference in the mean postoperative knee scores.More carefully designed randomized controlled trials are required to evaluate the difference of resurfacing versus nonresurfacing the patella in total knee arthroplasty.

OBJECTIVETo evaluate the long-term protection efficacy of neonatal hepatitis B vaccination on chronic hepatitis B (CHB) and liver fibrosis and cirrhosis in adults.

METHODSFrom January to October, 2013, a cross-sectional study was conducted among the participants from Qidong Hepatitis B Intervention Study (QHBIS), who were selected through stratified random sampling. The detections of serum alanine aminotransferase (ALT), HBsAg, anti-HBs, anti-HBc, HBeAg, and anti-HBe were conducted and ultrasonography on liver, gallbladder and spleen was performed for them. The positive rates of each serologic markers, the prevalence of active CHB and liver fibrosis and cirrhosis were calculated, the gender specific differences between vaccination group and control group were compared with Chi-square test.

RESULTSA total of 4 421 participants aged (25.59±1.84) years in vaccination group and 3 880 participants aged (26.61±2.24) years in control group were surveyed. The positive rates of HBsAg, anti-HBs, anti-HBc, HBeAg and anti-HBe were 2.38%, 37.73%, 3.78%, 0.57% and 2.15% in vaccination group, and 9.02%, 29.41%, 16.83%, 2.73% and 8.87% in control group, respectively, the differences between two groups were statistically significant (all P<0.05). The prevalence of active CHB and liver fibrosis and cirrhosis were 0.45% and 0.16% in vaccination group, 1.29% and 0.39% in control group, the differences between two groups were statistically significant (P<0.05). The active CHB prevalence was lower in females than in males in both vaccination group and control group (P<0.05). The liver fibrosis and cirrhosis prevalence was lower in females than in males in control group (P<0.05); whereas, no statistical significant difference in liver fibrosis & cirrhosis prevalence between males and females was found in vaccination group (P>0.05).

CONCLUSIONSProtection conferred by neonatal hepatitis B vaccination could last to marrying age. The gender specific difference in protection efficacy needs further study.
