Objective To discuss the role of intestinal flora imbalance in the pathogenesis of pouchitis. Methods The pouchitis rat model was established and the faeces sample and the mucous membrane sample were collected regularly, in which the bacterial nucleic acids were extracted for quantitative analysis of the intestinal flora in the samples through using the real-time quantitative PCR technique and high energy sequencing technology. Results The disorder phenomenon of the intestinal flora appeared at the 7th day of the experiment, and the pouchitis was presented at the 21st day of the experiment. At the 31st day of the experiment, compared to control group and non-pouchitis group, the quantity of Bifidobacterium and the Lactobacillus of the pouchitis model rats in the mucous membrane sample and the faeces sample were significantly decreased (P < 0.05), and the Bacteroidetes, Faecalibacterium prausnitzii and XIV Clostridium leptum subgroup in the mucous membrane of pouchitis were significantly decreased (P < 0.05). The IV Clostridium coccoides group was the main flora in the mucous membrane of pouchitis, the bacterial diversity of non-pouchitis group and control group was significantly higher than that of the pouchitis group (P < 0.05). Conclusions The intestinal flora imbalance is one of the factors that cause the incidence of the pouchitis; this study provides a clue of the pathogenesis and treatment direction of the intestinal inflammatory disease.

Objective: To evaluate the prognostic value of neutrophil-to-lymphocyte ratio (NLR) in patients with acute-on-chronic liver failure (ACLF) after glucocorticoid therapy. Methods: Thirty-six patients with acute-on-chronic liver failure (ACLF) were treated with glucocorticoid therapy, of whom 23 patients in the survival group and the other in the deceased group (n=13). The changes of white blood cells, neutrophils, lymphocytes, NLR, total bilirubin (TBil), prothrombin activity (PTA), international normalized ratio (INR) were observed before, during and after treatment, and the relationship between NLR and prognosis was analyzed. Results: NLR after glucocorticoid treatment, the survival group 3.95±2.65, the deceased group 12.79±10.66, there was significant difference between the two groups (P<0.001). According to univariate and multivariate logisitic regression analysis, NLR ratio was one of the independent factor in ACLF. ROC curve showed the AUC of NLR in patients with ACLF 0.868(95%CI: 0.743-0.993). After glucocorticoid treatment, the survival rate of NLR<3.315 patients with acute liver failure was high. Conclusions NLR is one of the important indexes for evaluating the prognosis of ACLF patients with ACLF due to glucocorticoid therapy.

Objective Reports are rarely seen on the clinical studies of pituicytomas. This article discusses the clinical diagnosis, treatment strategies, pathological features and postoperative complications of pituicytomas. Methods This retrospective study included 10 cases of pituicytomas treated in our hospital from July 2008 to July 2018. All the patients underwent microsurgery, gross total resection of the tumor in 6 cases and subtotal resection in the other 4. We analyzed the histopathological features, postoperative complications and follow-up data of the patients. Results The tumors were tightly organized morphologically, consisting of bipolar spindle-shaped cells, arranged like crosswise-woven fiber bundles or in a storiform pattern, the cytoplasm stained red and eosinophilic, the nuclei medium-sized, round, oval or spindle shaped, mildly heterotypical, with visible microencapsulation and abundant interstitial blood vessels. The main postoperative complications included insipidus in 8 cases, hyponatremia in 4, decreased visual acuity in 3, hypopituitarism in 2, and intracranial infection in 1. Of the 9 patients followed up, 1 experienced recurrence at 2 years postoperatively and received another surgery, with no more recurrence hitherto. Conclusion Definite diagnosis of pituicytoma depends on pathological examination, and adequate attention should be paid to the prevention and management of such postoperative complications as insipidus and hyponatremia.

OBJECTIVETo analyze and compare burden of disease caused by malignant tumor in China, 1990 and 2010.

METHODSThe indicators including prevalence, death, years of life lost (YLL), years lived with disability (YLD), and disability adjusted of life years (DALY) of malignant tumor from the results of Global Burden of Disease (GBD) 2010 were used to calculate the standardized prevalence rate, mortality rate, YLL rate, YLD rate and DALY rate with the 2010 national census data. The research described the prevalence, death, and burden of disease caused by malignant tumor and analyze the trend of these indicators in 1990 and 2010 in China.

RESULTSIn China from 1990 to 2010, the standardized prevalence rate of malignant tumor increased from 529.76/100 000 to 749.57/100 000 (increased by 41.49%); the standardized mortality rate decreased from 196.57/100 000 to 169.88/100 000 (decreased by 13.58%); the standardized DALY rate decreased from 5 206.56/100 000 to 4 150.86/100 000. In 2010, the top five standardized DALY rate of malignant tumor were lung cancer, liver cancer, gastric cancer, esophageal cancer, and colorectal cancer. Their standardized DALY rate were 892.21/100 000, 787.40/100 000, 521.36/100 000, 303.95/100 000, and 269.94/100 000, respectively. In all kind of malignant tumors, the burden of disease of lung cancer had the fastest-growing rate. The standardized mortality rate of lung cancer increased from 34.78/100 000 in 1990 to 41.09/100 000 in 2010; the standardized DALY rate increased from 830.77/100 000 in 1990 to 892.21/100 000 in 2010. The burden of disease of gastric cancer had the fastest-falling rate. The standardized mortality rate of gastric cancer decreased from 39.65/100 000 in 1990 to 23.79/100 000 in 2010; the standardized DALY rate decreased from 968.96/100 000 in 1990 to 521.36/100 000 in 2010.

CONCLUSIONThe burden of disease caused by malignant tumor in China remained at high levels in 2010. The top five burden of disease of malignant tumor were lung cancer, liver cancer, gastric cancer, esophageal cancer, and colorectal cancer. The burden of disease of lung cancer had the fastest-growing rate and gastric cancer had the fastest-falling rate from 1990 to 2010 in China. Prevention and control of malignant tumor was still difficult.

OBJECTIVETo explore the therapeutic method and efficiency of chronic radiation enteritis with intestinal obstruction.

METHODSClinical data of 51 patients of chronic radiation enteritis with intestinal obstruction from Aug. 2001 to Dec. 2006 were analyzed retrospectively.

RESULTSThe mean time from the ending of radiation to the occurrence of obstruction was (11.9 +/- 22.6) months. Conservative treatment, intestinal resection-anastomosis, enterostomy, bypass operation and enterolysis were applied and performed in above 51 cases. Two patients could not receive operation because of wild metastasis. One died of peritoneal bleeding after operation. Forty-eight cases were cured and the curative rate was 94.1%.

CONCLUSIONTherapeutic regimen should be chosen according to nutritional status and intestinal impairment in chronic radiation enteritis with intestinal obstruction.

OBJECTIVETo summarize the preliminary experience of laparoscopic surgery in the treatment of radiogenic small bowel damage.

METHODSClinical data of 12 patients with radiogenic small bowel damage undergoing laparoscopic operation in our department from January 2012 to January 2013 were retrospectively reviewed.

RESULTSTwo patients were transferred to laparotomy because of dense adhesion in the entire abdomen and uncertainty of metastatic malignancy, respectively. The laparoscopic surgery was successfully performed in other 10 patients. Three patients received enterostomy or colostomy because of intestinal obstruction or bleeding. Among the other seven patients who underwent intestinal resection and anastomosis, intestinal anastomosis was performed with an small adjunvant incision in the former two cases and performed under laparoscopy in the latter five cases. The post-operative complication included one anastomotic fistula.

CONCLUSIONLaparoscopic surgery can be safely used in radiogenic small bowel damage patients, which can avoid the delayed incision healing.

Objective: To assess the disease burden attributable to household air pollution in 1990 and 2013 in China. Methods: Based on data from the Global Burden of Disease Study 2013 in China (GBD 2013), we used population attributable fractions (PAF) to analyze the burden of different diseases attributable to solid-fuel household pollution in 2013 in China(not inclnding HongKang, Macao, Taiwan). We compared PAF, mortality, and disability-adjusted life years (DALY) for diseases attributable to solid-fuel household pollution in 31 provinces in mainland China in 1990 and 2013, and stratified the burden by age group. The estimated world average population during 2000- 2025 was used to calculate age-standardized mortality and DALY rates. Results: In 2013, 14.9% of lower respiratory infections in children <5, 32.5% of chronic obstructive pulmonary disease (COPD), 12.0% of ischemic stroke, 14.2% of hemorrhagic stroke, 10.9% of ischemic heart disease, and 13.7% of lung cancer were attributable to solid-fuel household pollution. In addition, 807 000 deaths were attributable to solid-fuel household pollution, including 296 000 from COPD, 169 000 from hemorrhagic stroke, 152 000 from ischemic heart disease, 88 000 from ischemic stroke, 75 000 from lung cancer, and 28 000 from lower respiratory infections in children <5. The age-standardized mortality rate from solid-fuel household pollution decreased by 59.3% from 158.8/100 000 in 1990 to 64.6/100 000 in 2013. The age-standardized mortality rate from solid-fuel household pollution decreased in all 31 provinces, with the highest decline observed in Shanghai (96.3%), and lowest in Xinjiang (39.9%). In 2013, the age-standardized DALY rate from solid-fuel household pollution was highest in Guizhou (2 233.0/100 000) and lowest in Shanghai (27.0/100 000). The DALY rate was the highest for the >70 age group (7 006.0/100 000). Compared with 1990, the 2013 mortality rate and DALY rate from solid-fuel household pollution decreased in all age groups, with the highest decline observed in the <5 age group (91.9% and 91.8% , respectively). Conclusion Although the disease burden attributable to household air pollution decreased notably between 1990 and 2013, household pollution caused a high number of deaths and DALY loss in certain western provinces.

Objective: To analyze the burden of disease attributable to low fruit intake among Chinese population aged ≥15 years old between 1990 and 2013. Methods: We used data from the 2013 Global Burden of Disease Burden of Disease Study to study the situation in China. The population attributable fraction was calculated to estimate and compare the death and disability-adjusted life years (DALY) attributed to low fruit intake between 1990 and 2013 in China (excluded Taiwan, China). An average world population age structure of the period 2000-2025 was adopted to calculate age-standardized rates. Results: Deaths attributable to low fruit intake accounted for 11.02% of all death in 2013, which were higher than it in 1990 (10.38%). In 2013, the number of deaths attributed to low fruit intake in China increased to 1 046 500 from 793 800 in 1990. From 1990-2013, the age-standardized death rate attributable to low fruit intake decreased from 113.04/100 000 to 79.80/100 000. DALYs caused by low fruit intake increased from 18.346 5 million in 1990 to 21.296 7 million in 2013. Compared with 1990, the age-standardized DALY rate attributed to low fruit intake decreased by 34.67%. In 2013, the top three provinces with the highest burden of disease attributed to low fruits intake were Tibet, Guizhou and Xinjiang provinces, with standardized DALY rate at 2 612.53/100 000, 2 281.85/100 000 and 2 198.22/100 000, respectively. Compared with the results in 1990, the standardized DALY attributed to low fruits intake decreased, especially in Tianjin, where decreased by 63.61%; followed by Aomen, Zhejiang, Shanghai and Beijing, where decreased by 59.74%, 59.53%, 56.64% and 53.88%, respectively. Conclusion Compared with the situation in 1990, the burden of disease attributable to low fruit intake decreased in 2013, but the situation is still serious, especially in Tibet, Guizhou and Xinjiang provinces, where the burden decreased comparatively slowly.

Background::Studies that comprehensively address the characteristics of centenarian deaths are rare. The present study aimed to depict the characteristics of centenarian deaths in China and their changing trends.Methods::Data on centenarian deaths between 2013 and 2020 were obtained from the national mortality surveillance system of China, including date, place of death (PoD), and underlying cause of death (CoD). Descriptive analyses were performed to understand the epidemiological characteristics, and a joinpoint regression model was adopted to examine the changing trends in the proportions of different PoDs, CoDs among centenarians, and centenarian deaths accounting for all deaths and deaths among people aged 65 years and older.Results::There were 46,938 registered centenarian deaths between 2013 and 2020 that included 34,311 females (73.10%) and 12,627 males (26.90%). January (12.05%), February (9.99%), and December (9.74%) were the top three months with the highest number of deaths. The proportions of deaths that occurred in homes, hospitals, and nursing homes were 81.71%, 13.63%, and 2.68%, respectively. The proportion of deaths in nursing homes increased by 9.60% (95% confidence intervals [CIs], 6.4-12.9%) from 2014 to 2020. Heart disease (35.72%) was the leading cause of death, followed by respiratory diseases (17.63%), cerebrovascular disease (15.60%), and old age (11.22%). The proportion of respiratory diseases decreased by 4.8% (95% CI, -8.8 to -0.7%), and the proportion of deaths from old age decreased by 2.3 % (95% CI, -4.4 to -0.1%) per year. Shanghai had the highest proportions of deaths in hospitals (39.38%) and nursing homes (14.68%). Sichuan had the highest proportion of deaths attributed to respiratory diseases (32.30%), while Jiangsu (26.58%) and Zhejiang (23.61%) had the highest proportions of deaths from old age.Conclusion::Unlike other countries, centenarian deaths in China are characterized by a higher proportion of home and heart disease deaths, and this death pattern differs across provinces.

Objective To analyze the death status of disease burden of cardiovascular and circulatory diseases in 1990 and 2010 in China, and to provide the basic information for cardiovascular and circulatory disease prevention and control. Methods Using the results of the Global Burden of Diseases Study 2010(GBD 2010) to describe the cardiovascular and circulatory diseases deaths status and disease burden in China. The measurement index included the mortality, years of life lost due to premature mortality (YLL), years lived with disability (YLD), and disability-adjusted life years (DALY). At the same time, we used the population from 2010 national census as standard population to calculate the age-standardized mortality rate and DALY rate, YLL rate and YLD rates which will describe the mortality status and disease burden of total and different types of cardiovascular disease. We also calculated the change in 1990 and 2010 for all indexes, to describe the change of the burden of disease in the 20 years. Results In 2010, the total deaths of cardiovascular and circulatory diseases reached 3.136 2 million, the mortality rate reached 233.70 per 100 000 people and the age-standardized mortality rate was 256.90 per 100 000 people. The total DALYs, YLLs, and YLDs of cardiovascular and circulatory diseases reached 58.2055, 54.0488, and 4.1568 million person-years, respectively, and the age-standardized DALY rate, YLL rate and YLD rate were 4 639.04, 4 313.13, 325.91 per 100 000. In 1990, the deaths only 2.1675 million and the DALYs, YLLs and YLDs were 45.2679, 42.2922, and 2.9757 million person-years. The age-standardized mortality rate was 300.30 per 100 000 people. And the age-standardized DALY rate, YLL rate and YLD rate were 5 872.58, 5 523.42 and 349.16 per 100 000. Compared with the result in 1990, the total deaths, DALYs, YLLs, and YLDs were increased 44.72%, 28.58%, 27.80%, and 39.68%, respectively, while the age-standardized mortality rate, age-standardized DALY rate, age-standardized YLL rate, and age-standardized YLD rate were decreased 14.45%, 21.01%, 21.91%, and 6.66%, respectively. In 1990 and 2010, cerebrovascular disease caused the most DALYs (24.8768 and 30.1389 million person-years, respectively) compared with other types of cardiovascular and circulatory diseases, and followed by ischemic heart disease (10.1270 and 17.8858 million person-years). And the YLLs of cerebrovascular disease (24.3436 and 29.1726 million person-years) also the highest in different type of cardiovascular and circulatory diseases, ischemic heart disease ( 8.9919 and 16.0839 million person-years) was the second highest. The deaths of cerebrovascular disease and cerebrovascular disease increased from 1 340.6 and 450.3 thousands in 1990 to 1 726.7 and 948.7 thousands in 2010, respectively. The age-standardized mortality rate and DALY rate of cerebrovascular disease were decreased from 187.19 and 3 335.37 per 100 000 people in 1990 to 141.43 and 2 409.09 per 100 000 people. While in the ischemic heart disease, the age-standardized mortality rate, and DALY rate were increased form 62.53 and 1 318.38 per 100 000 people in 1990 to 77.89 and 1 428.31 per 100 000 people. Conclusion Burden of cardiovascular and circulatory disease became more and more serious in China, of which the cerebrovascular disease and ischemic heart disease were most serious.
