Enlargement of lymph nodes in the masses and retroperitoneum in 2 cases were seen,respectively.4 patients had abdominal operations,one patient was in combination with carcinoma of head of pancrease.Conclusion Certain features of the CT manifestations of mesenteric panniculitis can be found,CT is effective for the diagnosis of mesenteric panniculitis.

Objective To investigate the prognostic value of metabolic parameters of 18F-fluorodeoxyglucose positron emission tomography/computed tomography(FDG PET-CT)before radiotherapy in patients with esophageal cancer receiving radiotherapy. Methods We retrospectively analyzed the clinical data of 37 patients with stage Ⅱ-Ⅲ esophageal squamous cell carcinoma admitted to Anhui Provincial Hospital from 2010 to 2015,who underwent PET-CT scans within 4 weeks before radiotherapy. The following information was collected:age,sex,the location of primary lesion,clinical stage,and treatment regimen.The maximum standard uptake value(SUVmax), mean standard uptake value(SUVmean), metabolic tumor volume(MTV), PET tumor length(PTL),and total lesion glycolysis(TLG)were calculated. The optimal cut-off values of SUVmax, SUVmean,MTV,PTL,and TLG were determined by the receiver operating characteristic(ROC)curve. The Kaplan-Meier method was used to calculate survival rates,and the log-rank test was used for survival comparison and univariate prognostic analysis;the Cox model was used for multivariate prognostic analysis of significant variables. Results The area under the ROC curve suggested that MTV>TLG>PTL=0.713>0.679>0.670. The Kaplan-Meier survival analysis showed that patients had better survival time when MTV was less than 27.44 cm3,TLG was less than 166.2 g,and PTL was less than 36.74 mm(P<0.05).The Cox multivariate regression analysis showed that only MTV was an independent prognostic factor for radiotherapy in patients with esophageal cancer(P=0.000). Conclusions MTV, TLG and PTL have certain values in predicting the prognosis of patients with esophageal cancer before radiotherapy, and are helpful for selecting and adjust the clinical treatment regimen and improving the survival rate and prognosis.

Objective Inflammatory bowel disease(IBD)is an unexplained chronic and recurrent inflammatory disease of the intestine,including ulcerative colitis(UC)and Crohn′s disease(CD).At present, the etiology and pathogenesis of IBD are still not clear,and it is believed to be related to the environment, inheritance,infection,immunity and other factors.With the increase of people′s living standard and the economic and social development,the incidence of IBD in China is a rising trend year by year,the impact of diet on the incidence of IBD and the influence of nutritional support on the prognosis of IBD have attracted more and more attention.Vitamin is one of the seven nutrients and is an indispensable part of the health of the body.In recent years,some vitamins have been proved to be related with the occurrence and development of IBD.

Objective:To evaluate the effect of breathing training method and time on postoperative pneumonia in patients with lung cancer, so as to provide a reference for postoperative pneumonia prevention and control.Methods:A systematic retrieval of PubMed, Web of Science, Chinese Biomedical Literature Database, CNKI and other databases was conducted to collect RCTS of lung cancer patients undergoing respiratory training combined with respiratory trainers on the basis of routine nursing during perioperative period. The retrieval period was from the establishment of database to April 2021. According to inclusion and exclusion criteria, literature was screened and extracted, and literature quality was evaluated. Meta-analysis was performed using RevMan 5.4 software.Results:Finally, a total of 9 RCT articles were included, including 1 239 cases of lung cancer surgery patients. Among them, there were 624 cases in the control group and 615 cases in the intervention group. Meta-analysis results showed that compared with conventional nursing, combined breathing training with breathing trainer could reduce the incidence of postoperative pneumonia [ RR=0.38, 95% CI (0.26, 0.57) , P<0.000 01]. Combined breathing trainer intervention for 1 week [ RR=0.27, 95% CI (0.14, 0.52) , P<0.000 1], intervention frequency for more than 4 times /d[ RR=0.36, 95% CI (0.23, 0.57) , P<0.000 1], duration of single breathing training for more than or equal to 15 min[ RR=0.34, 95% CI (0.20, 0.58) , P<0.000 1) reduced the incidence of pneumonia in patients. Conclusions:In the perioperative period, respiratory training combined with respiratory trainer on the basis of routine nursing, training frequency for more than 4 times /d, duration of single breathing training for more than or equal to 15 min can improve lung function of patients undergoing lung cancer surgery and reduce the incidence of postoperative pneumonia, which is worthy of clinical application.

Objective:To systematically review the effect of information technology-based transitional care on the treatment effect of children and adolescents with type 1 diabetes mellitus (T1DM) , so as to provide a reliable scientific basis for their out-of-hospital transitional care.Methods:Randomized controlled trial (RCT) of information technology continued nursing intervention for children and adolescents with T1DM in PubMed, Web of Science, CNKI and other databases were searched by computer. The retrieval time was from the establishment of databases to July 31, 2021. According to inclusion and exclusion criteria, literature was screened and data was extracted. Cochrane was used to evaluate the risk of bias for literature quality. Meta-analysis was performed using RevMan 5.4 software, and subgroup analysis was conducted on intervention methods, duration and intervention objects of different ages.Results:Finally, a total of 12 literatures were included, and the quality of literatures was medium. A total of 1 353 cases were included. The results of meta-analysis showed that there were significant differences in the glycated hemoglobin value and the incidence of acute complications between the information technology transitional care group and the traditional nursing group ( P<0.05) . Subgroup analysis showed that different intervention methods (App, Internet platform) and duration of intervention had significant differences in the effect of out-of-hospital treatment for children and adolescents with T1DM ( P<0.05) . Conclusions:The use of information technology-based transitional care can improve out-of-hospital glycosylated hemoglobin value and reduce the incidence of acute complications in children and adolescents with T1DM. Different intervention methods (App, Internet platform) and different intervention time can improve the out-of-hospital treatment effect of children and adolescents with T1DM. It is suggested to promote information technology continuation care in out-of-hospital treatment of children and adolescents with T1DM.

Objective: To explore the relationship between smoking and hyperuricemia in Chinese residents. Methods: Based on data from the China Health and Nutrition Survey (CHNS), residents with blood samples provided in the 2009 round (including information of socio-demographic factors, lifestyle behaviors, medical history, and laboratory examinations etc.) were selected as the participants in the current analysis. Unconditional logistic regression models were utilized to compute the ORs and corresponding 95%CIs for assessing the relationship between smoking and hyperuricemia. Results: Among the 8 785 subjects, 1 435 had hyperuricemia with a prevalence rate of 16.3%, consisting of 886 men and 549 women with prevalence rates of 21.6% (886/4 110) and 11.7% (549/4 675) , respectively. Compared with never smokers, the adjusted OR (95%CI) for hyperuricemia was 0.83 (0.70-0.98) among current smokers, 0.77 (0.63-0.94) among current smokers with 20-39 years of smoking, and 0.79 (0.65-0.97) among current smokers with 11-20 cigarettes per day. When stratified by gender and compared with non-smoker, the adjusted OR (95%CI) for hyperuricemia among current smokers compared with never smokers was 0.83 (0.70-0.98) among men, while no significant association was found in female current smokers (OR=0.73, 95%CI: 0.42-1.26, P=0.260). Conclusion In Chinese residents, there is an inverse association between smoking and hyperuricemia prevalence, and this association may be related to duration and intensity of smoking among current smokers. The findings need to be validated in large prospective cohort studies.

Objective To explore the effectiveness of a myoelectricity-driven hand robot on the recovery of hand motor function early after a stroke.Methods Thirty stroke survivors were randomly assigned to either a control group (n=15) or an experimental group (n =15).Both groups received routine rehabilitation exercises,while the experimental group additionally received hand training using a robotic hand exoskeleton.Before and after 4 weeks of treatment,the motor function of the wrist and fingers in both groups were measured using the Fugl-Meyer assessment.Spasticity in the index,middle,ring and little fingers was quantified using the modified Ashworth scale.The muscle force of the fourth finger,thumb and all of the fingers during maximum voluntary extension and flexion were recorded using the robot's surface electromyography system.Results Significant increases in the average Fugl-Meyer scores in both groups were observed after 4 weeks of treatment,but the experimental group's average score was by then significantly higher than that of the control group.The experimental group's average Ashworth score and the average sEMG amplitudes were also significantly better than those of the control group.Conclusion Supplementing routine rehabilitation exercises with a hand robot can improve hand motor function and muscle force significantly,as well as relieving hand spasticity early after a stroke.

Objective:To systematically review research on the association between vitamin K and type 2 diabetes and diabetes-related biomarkers in humans, and evaluate the role of vitamin K in the prevention of type 2 diabetes.Methods:"Vitamin K", "type 2 diabetes" and related terms were searched in PubMed, EMBASE, China National Knowledge Infrastructure (CNKI) and Wanfang Med Online up to November 2018.Results:A total of 1 Chinese and 12 English articles were included. Among 6 observational studies, 5 of them showed that higher dietary vitamin K intake and plasma vitamin K level were associated with the decrease of the risk of type 2 diabetes. Among 6 clinical intervention studies, 5 of them indicated that the supplementation of vitamin K 1 or K2 could have positive influence on insulin metabolism. One Mendelian randomization study showed higher circulation vitamin K level might reduce the risk of type 2 diabetes. Conclusion:Vitamin K plays an important role in the prevention and control of type 2 diabetes, which may be related to the improvement of insulin metabolism and blood glucose level.

ObjectiveTo explore the sensory processing characteristics of preschool children with autism spectrum disorder （ASD）， and to provide a theoretical basis for early screening and intervention training of ASD. MethodsA total of 215 preschool children with ASD and170 typically developed （TD） children were investigated with a basic situation questionnaire and sensory processing measure （SPM）. The two groups were stratified according to age and gender， and the differences of scores in sensory domains were compared to analyze the sensory processing characteristics of preschool children with ASD. ResultsThe scores of social participation， vision， hearing， touch， taste and smell， body awareness， balance and motion， planning and ideas， and total sensory system in children with ASD were all higher than those in children with TD （all P<0.01）. The highest degree of abnormality was found in hearing and the lowest degree in taste and smell in children with ASD. The results of Spearman correlation analysis showed that in the 4-year-old and 5-year-old children with ASD， the scores of vision （r_s=-0.200， P= 0.033） and hearing （r_s=-0.194， P=0.040） decreased with age. There was no correlation between the scores of other developmental quotients and age （all P>0.05）. Boys and girls with ASD had higher scores in all developmental quotients than TD children （P<0.01）. However， there was no significant gender difference in any developmental quotients of ASD children （all P>0.05）. ConclusionSensory processing abnormalities are common in preschool children with ASD， which are different from those of TD children in multiple sensory domains. Sensory processing abnormalities may be used as an indicator for early screening of ASD， and it is necessary to conduct corresponding intervention training for sensory processing abnormalities in children with ASD.
