Objective To systematically evaluate the value of narrow band imaging(NBI)and iodine staining in early diagnosis of esophageal cancer and precancerous lesions.Methods The databases of PubMed,Embase,CNKI,VIP technological journals and Wanfang digital journals were retrieved by computer for searching the literatures on the value of NBI and iodine staining in diagnosing early esophageal cancer and precancerous lesions.The Meta-Disc 1.4 software was used to conduct the meta analysis and calculate the pooled sensitivity,specificity and 95％ confidence interval(95％ CI).Summary receiver operating characteristic(SROC)curve was drawn and the area under curve(AUC)was calculated,thus the diagnostic values of the two methods were evaluated.Results Totally 13 articles were included,including 975 patients.The pooled sensitivity and specificity for NBI were 0.88(95％CI=0.86 to 0.90)and 0.79(95％CI=0.76 to 0.82).The pooled sensitivity and specificity for iodine staining were 0.95(95％CI=0.93 to 0.97)and 0.45(95％CI=0.40 to 0.49).AUC of SROC for the two methods were 0.938 6 and 0.952 9 respectively.There was no statistically difference in the AUC values between the two methods(Z=0.519,P>0.05).Conclusion NBI and iodine staining are both effective ways in the diagnosis of early esophageal cancer and precancerous lesions.And both of them have a certain clinical value.

Objective To investigate hospitalized children's nutritional risk and malnutrition occurrence,and to provide clinical basis for nutrition support.Methods Nutritional risk screening tool STRONGkids was applied to 651 cases of hospitalized children with nutritional risk screening,and through physical measurement to assess children' s nutritional status,at the same time during the patient's diagnosis,the length of time data for analysis was recorded.Results Of 651 cases of hospitalized children,7.07％ (46 cases) were of highly nutritional risk,80.95％ (527 cases) with moderate nutrition risk,and 11.98％ (78 cases) were of low nutrition risk.Malnutrition rate was 22.58％,moderate malnutrition in 111 cases (17.05％),severe malnutrition in 36 cases (5.53％).The first three high risk diseases were congenital heart disease,chronic liver disease and chronic kidney disease(x2 =21.43,P ＜0.01).According to the result of nutrition evaluation concluded with congenital heart disease,chronic kidney disease occurred with severe malnutrition was far higher than other diseases(x2 =16.53,P ＜ 0.05).Children with highly nutritional risk were more likely to have weight loss than the children with relatively low nutritional risk (P ＜ 0.05),and their length of hospital stay were obviously longer than the children with low or moderate nutritional risk (P ＜ 0.05).Conclusions The hospitalized children have high incidence of malnutrition,and different nutritional risks lead to different clinical outcomes.STRONGkids score method helps to evaluate nutritional risk in hospitalized children and detect malnutrition and potential deterioration,which is conducive to early comprehensive nutritional assessment and proper nutritional treatment,thus to improve their clinical outcomes.

Objective To investigate the effects of acupoint catgut-embedding therapy(ACT) on hypothalamic of hypothalamic norepinephrine(NE),dopamine(DA),5-hydroxytryptamine(5-HT),5-hydroxyindole acetic acid(5-HIAA) in menopause rats,and to explore the preventive and therapeutic mechanism of ACT for climacteric syndrome.Methods Sixty female SD rats were equally randomized into treatment group,model group and sham-operation group.Except the rats in the sham-operation group,the rats in other groups received removal of bilateral ovaries to establish ovariectomized menopause rat models.The treatment group received catgut-embedding on acupoints of Shenshu,Sanyinjiao and Zigong,once per week,and the treatment lasted 4 weeks.After treatment,the hypothalamic NE,DA,5-HT,5-HIAA levels were measured by radioimmunoassay.Results NE and DA levels were significantly decreased(P

Objective To investigate whether Tian Jiu therapy can regulate Th1/Th2 ratio effectively for bronchial asthma patients.Methods A total of 30 bronchial asthma patients who were treated with Tian Jiu therapy in the hospital were enrolled in the study as patients group and 20 healthy individuals were enrolled as control group.The mRNA of T-bet,GATA3,Foxp3 and STAT-6 were detected by using realtime-PCR,while IFN-γ and IL-4 were detected by using ELISA for control group and patents group before and after treatment. Flow cytometry was used to detect Th1/Th2 ratio.Results After Tian Jiu therapy,Th2 proportion decreased and Th1/Th2 ratio increased,secretion of IFN-γ decreased,mRNA of T-bet and GATA3 significantly in-creased,while STAT-6 decreased significantly(P<0.05).Conclusion Tian Jiu therapy has therapeutic effect on bronchial asthma patients through decreasing Th2 proportion and regulating Th1/Th2 ratio.
