Prevalence and risk factors of Helicobacter pylori infection in Qinghai Province / 中华消化杂志

Objective:To investigate the prevalence and the risk factors of Helicobacter pylori( H. pylori) infection in Qinghai Province with a multi-center cross-sectional study. Methods:From May to December in 2021, stratified sampling was conducted in Xining City, Haidong agricultural district, Hainan Tibetan Autonomous Prefecture, Haibei Tibetan Autonomous Prefecture and Yushu Tibetan Autonomous Prefecture by 20 centers, including the Affiliated Hospital of Qinghai University, Qinghai Red Cross Hospital and Qinghai Renji Hospital, etc. A questionnaire survey was carried out among the individuals undergoing routine health checkups. The questionnaire included general information, lifestyle and family history, etc. 13C-urea breath test was performed to diagnose H. pylori infection. Chi-square test, trend Chi-square test, segmentation method and multivariate logistic regression analysis were performed for statistical analysis. Results:The infection rate of H. pylori in Qinghai area was 53.6% (2 531/4 724). The age distribution of infection was statistically significant ( χ2=15.95, P=0.007), the infection rate in individuals aged 15 to<30 was higher than that of individuals aged 60 to< 75 (57.6%, 626/1 086 vs.49.5%, 231/467), and the difference was statistically significant ( χ2=8.83, P=0.003). With the increase of age, the infection rate decreased in female over 30 years old ( χ2trend=5.89, P=0.015). There were statistically significant differences in H. pylori infection rate among different ethnic groups ( χ2=28.13, P<0.001); the infection rate of Tibetan population was higher than that of Han population (62.9%, 313/498 vs. 51.5%, 1 804/3 503), and the difference was statistically significant ( χ2=22.56, P<0.001). The H. pylori infection rate in people living at an altitude >3 500 m was higher than that of people living at an altitude between 1 500 m and 3 500 m (61.8%, 327/529 vs. 52.5%, 2 204/4 195), and the difference was statistically significant ( χ2=16.25, P<0.001). Compared with those without corresponding habits, the infection rate of H. pylori was higher in smokers (62.1%, 1 081/1 740 vs. 48.6%, 1 450/2 984), in people who had the habit of eating hand grabbed mutton (55.4%, 967/1 744 vs. 52.5%, 1 564/2 980), raw garlic (55.5%, 968/1 744 vs. 52.4%, 1 563/2 980), spicy food (55.6%, 1 471/2 647 vs. 51.0%, 1 060/2 077), sweet food (55.2%, 1 187/2 149 vs. 52.2%, 1 344/2 575), the infection rate of tea drinkers was lower (50.5%, 1 135/2 247 vs. 56.4%, 1 396/2 477), and the differences were statistically significant ( χ2=80.94, 3.89, 9.63, 4.36, 4.13 and 16.19, all P<0.05). The results of logistic regression analysis indicated that Tibetan ( OR=1.379, 95% confidence interval (95% CI) 1.120 to 1.699), the Hui people ( OR=1.362, 95% CI 1.117 to 1.662), living at an altitude over 3 500 m ( OR=1.355, 95% CI 1.107 to 1.657), smoking ( OR=1.847, 95% CI 1.629 to 2.094), and spicy food ( OR=1.224, 95% CI 1.084 to 1.382) were independent risk factors of H. pylori infection (all P<0.05). Conclusions:The infection rate of H. pylori in Qinghai Province is higher than the average level in inland China. The infection rate of people with different ages, nationalities, altitudes of residence, occupations, living and eating habits were different. The infection rate of female over 30 years old is decreasing year by year. The infection risk is high in Hui people and Tibetan, spicy food lovers, smokers and people living at an altitude >3 500 m.

Isoflurane preconditioning inhibits caspase-11-related noncanonical pyroptosis pathway to alleviate hepatic ischemia-reperfusion injury in mice / 南方医科大学学报

OBJECTIVE@#To study the protective effect of isoflurane preconditioning on hepatic ischemia-reperfusion (I/R) injury mediated by the noncanonical pyroptosis pathway.@*METHODS@#Thirty C57BL/6 mice were randomly divided into sham-operated group, isoflurane group and I/R group, and in the latter two groups, hepatic I/R injury was induced by clamping the portal vein for 30 min. In isoflurane group, the mice were pretreated with 1.4% isoflurane 30 min before the surgery. The protective effect of isoflurane preconditioning against hepatic I/R injury was evaluated by assessing the pathological score of HE staining of the liver tissue and serum ALT and AST levels. Serum IL-1β and IL-18 levels and the protein expression of GSDMS were detected by ELISA and Western blotting to evaluate the inhibitory effect of isoflurane preconditioning on pyroptosis. Western blotting and immunofluroescence were used to detect the protein expression of caspase-11 in the liver tissues to evaluate the inhibitory effect of isoflurane preconditioning on noncanonical pyroptosis pathway.@*RESULTS@#The Suzuki's score of the liver tissue was significantly higher in I/R group than in the sham group ( < 0.05), while the score in the isoflurane group was significantly lower than that in the I/R group ( < 0.05). Serum ALT and AST levels significantly increased in the sham group ( < 0.05), and were significantly lower in isoflurane group than in I/R group ( < 0.05). The serum levels of IL-1β and IL-18 were significantly higher in I/R group than in sham group ( < 0.05), and were significantly lower in isoflurane group than in I/R group ( < 0.05). The expression of GSDMD in the I/R group was significantly higher than that in sham group, and was significantly lower in isoflurane group than in I/R group ( < 0.05). The hepatic expression of caspase-11 was significantly higher in I/R group than in sham group ( < 0.05), and was significantly lower in isoflurane group than in I/R group ( < 0.05).@*CONCLUSIONS@#Isoflurane preconditioning has protective effect against hepatic I/R injury, which is related to the inhibition of the noncanonical pyroptosis pathway.

Effect of nursing mode based on Omaha framework on nutrition intervention of low-weight patients with chronic obstructive pulmonary disease / 中国中西医结合急救杂志

Objective To explore the effect of Omaha system nursing model on nutritional status and disease condition of patients with low body mass and chronic obstructive pulmonary disease (COPD). Methods Sixty COPD patients with low body mass who were admitted to the First Affiliated Hospital of Huzhou University from January 2015 to November 2016 were enrolled, and they were randomly divided into an Omaha system nursing model group and a routine care intervention group, with 30 cases in each group. The Delphi expert consultation method was used to construct the Omaha nursing problem system and intervention system for COPD patients with low body mass. The patients in the routine care intervention group were given routine care intervention; the patients in the Omaha system nursing model group underwent nutritional intervention according to the Omaha system nursing model. The Mini Nutritional Assessment (MNA), COPD Assessment Test (CAT) and the modified Medical Research Council Dyspnea Scale (mMRC) were used to be the evaluation system of the Omaha system nursing model, the changes of MNA, CAT and mMRC evaluation scores on admission and in 1, 3, and 6 months after discharge in the two groups were recorded, and the correlations between MNA score and CAT, mMRC scores were analyzed. Results Omaha system analysis showed that the main health problems of the Omaha system nursing model group were distributed in the environmental (17.86%), social psychological (8.93%), physiological (19.64%), and health-related behavioral (53.57%) aspects, among which health-related behaviors were mostly common. There were no statistical significant differences in the scores of CAT, mMRC, and MNA between the two groups on admission (all P > 0.05). The CAT and mMRC scores of the Omaha system nursing model group in 1, 3, and 6 months after discharge were significantly lower than those on admission (CAT score: 16.98±2.39, 16.67±2.55, 15.36±2.17 vs. 25.76±3.67; mMRC score: 2.35±0.57, 1.97±0.52, 1.49±0.51 vs. 3.07±0.55, all P < 0.05), MNA scores were significantly higher than those on admission (11.89±3.57, 13.97±3.52, 15.49±3.51 vs. 10.33±3.02, all P < 0.05), and along with the prolongation of time the decrease and increase in scores were more significant. The scores of the Omaha system nursing model group were improved more significantly in 1, 3 and 6 months after discharge than those of the routine care intervention group (CAT score: 16.98±2.39, 16.67±2.55, 15.36±2.17 vs. 23.01±2.67, 21.15±2.79, 19.06±2.61; mMRC score: 2.35±0.57, 1.97±0.52, 1.49±0.51 vs. 3.06±0.65, 3.06±0.61, 2.65±0.67;MNA score: 11.89±3.57, 13.97±3.52, 15.49±3.51 vs. 9.96±3.15, 10.06±3.09, 8.55±3.17, all P < 0.05]. Pearson correlation analyses showed that MNA score was significantly negatively correlated with CAT score (r = -0.493, P = 0.001) and with mMRC score (r = -0.594, P = 0.001) respectively. Conclusion Using the Omaha system nursing model for nutrition intervention in COPD patients with low body mass can significantly improve their nutritional status and disease condition as well as quality of life.

Objective To investigate the clinical effect of lung equivalent uniform dose (LEUD)-based predictive model for radiation pneumonitis (RP) induced by volumetric modulated arc therapy (VMAT) and to determine the optimal a value.Methods A total of 65 patients with primary lung cancer who received VMAT from July 2015 to February 2016 were divided into RP group and non-RP group according to the presence or absence of RP after radiotherapy.Their dose-volume histogram (DVH) data and other data were obtained and analyzed by the self-compiled numerical analysis program.The LEUD values in the two groups were calculated at a=[-50, 50], and then the a value was identified when the relative difference of LEUD between the two groups was maximal.The paired t test was used for analyzing the differences in V5, V20, V30, minimum lethal dose (MLD), and LEUD (aoptimal) between the two groups.A Pearson correlation analysis was used to determine the correlation of Vdose and LEUD (aoptimal) with RP.The logistic regression method was used to establish the predictive model of RP.Results The maximum relative difference in LEUD between RP group and non-RP group was obtained at a=0.3(627.94 cGy vs.510.23 cGy, relative difference[R]=23.07%).R decreased slowly at t=[-50,-5], increased sharply at t=[-5, 0], and reached the maximum value at a=0.3.After a rapid decrease at a=[0.3, 4], R decreased slowly at a=[4, 50].The correlation analysis of the traditional physical volume dose threshold also showed that the LEUD (at a=0.3) was correlated with V5, V10, V20, and MLD (r=0.929, P<0.05).Conclusions For patients receiving VMAT for thoracic cancer, LEUD (at a=0.3) can distinguish between patients with and without RP.Therefore, LEUD is recommended to be<510 cGy.A combination of LEUD and conventional physical dose has a good clinical predictive value for RP under non-uniform irradiation.
