Objective To observe the effect of Chinese medicine to wash, acupressure and Avene cream to moistur-ize for infantile eczema.Methods 100 babies who were diagnosed infantile eczema were chosen and separated to interven-tion group and control group randomly.The control group was treated by Chinese medicine to wash, acupressure and cream to moisturize, and the intervention group was treated by hormone medicine and Avene cream to moisturize.Observe the treat-ment effect after 7 days, 14days and 1 week after cured.Results The severity,effective rate and cure rate of two groups after 7days haven′t the statistical difference(p>0.05), and the severity of intervention group after 14days was lower than that of control group (p<0.05),the effective rate of intervention group after 14days was higher than and that of control group (p<0.05), and the recurrence rate of intervention group was lower than that of control group (p<0.05).Conclusion Combi-ning traditional Chinese and western medicine treatment can promote the treatment effect of infantile eczema , and reduce the recurrence, should be generalization.

Objective To study the family environment and the behavior of children with emotional disorder(ED ).Methods Thirty children with ED and 30 healthy children were assessed with family environment scale-Chinese version(FES-CV),and Achenbach CBCL.Results The scores on the items of intimateness,emotion,independence,and entertainment among Children with ED had by FES-CV were lower,but the scores on conflicts and control higher than the health controls(P<0?05).The total scores on social abilities as well as the dimensions were all lower than the healthy controls(P<0?01).The total scores on behaviors as well as the dimensions were higher than the controls(P<0?05).Conclusions Children with ED have more behavior problems,which are associated with their poorer family environment.Therefore,the family members should help and support each other to create a healthy environment for children growth.

【Objective】To explore the relationship of pathological changes,clinical manifestations and results of laboratory examination with TCM syndromes in patients with IgA nephropathy.【Methods】With parameters in Memphis renal biopsy accessing system and principle syndromes and complicated syndromes in differentiation criteria of chronic nephritis as reference,pathological changes and clinical manifestations of IgA nephropathy were classified by principle component analysis and factor analysis.The regression equations of different syndromes were established after a regression analysis of the principle components of pathological changes and clinical manifestations with the standard syndromes.【Results】(1)With the parameters in Memphis renal biopsy accessing system as reference,the principle components(reflecting over 85% information of glomerular changes)of pathological changes in 123 IgA nephropathy patients were glomerulosclerosis,crescent,stroma,immunofluorescence IgA and complement 3(C_3).With principle syndromes and complicated syndromes in differentiation criteria of chronic nephritis as reference,the principle components(reflecting over 90% information of syndrome manifestations)were lassitude and weakness for deficiency syndrome,cold limbs,white tongue and slippery fur and deep-thready pulse for yang-deficiency syndrome,and dry mouth and throat,red tongue and thready pulse for yin-deficiency syndrome.For liver-stagnation syndrome,the principle components were impatience and irritability,bitterness in mouth,frequent sighing and wiry pulse;for bloodstasis syndrome,the principle components was purple tongue with ecchymosis;for phlegm-damp syndrome,the principle components were heaviness of limbs,greasy fur,abdominal distension and impaired appetite;for heat-toxic syndrome,the principle components were sore throat,purulent sore and yellowish tongue with dry fur;for damp-heat syndrome,the principle components were bitterness and stickiness in mouth,and yellowish greasy fur.(2)The regression equations of syndromes of yin deficiency,yang deficiency,yin-yang deficiency,blood stasis,phlegm damp and liver stagnation were obtained.(3)The results of non-conditional Logistic regression analysis showed that yang-deficiency syndrome was correlated with edema,the incidence of yang deficiency in edema patients being 1.6 times of that in patients without edema;yin-deficiency syndrome was positively correlated with gross hematuria,the incidence of yin deficiency in patients with gross hematuria being 1.5 times of that in patients without gross hematuria;pain in waist and back was the common signs in patients with yin deficiency,yang deficiency and yin-yang deficiency.【Conclusion】Parameters of glomerulosclerosis,crescent,stroma,immunofluorescence IgA and C_3 reflect over 85% information of glomerular changes in IgA nephropathy patients;there exists a relationship of TCM syndrome with pathological changes and clinical manifestations;yang-deficiency syndrome is correlated with edema and yin-deficiency syndrome is correlated with gross hematuria.

Patients with systemic lupus erythematosus (SLE)are susceptible to influenza virus infection due to autoimmune disorder,use of glucocorticoids and the immunosuppressive agents.Influenza virus infection affects the disease stability,and the mortality of influenza virus infection in SLE patients is 5 times higher than that in general people infected by influenza virus.Vaccination is the most effective measure to prevent influenza virus infection.There is lack of studies on the influenza immunization in SLE patients in China,so this paper reviews prevention effect and safety of inoculation,the immune response to vaccine as well as the factors influencing immune response in influenza vaccination for SLE patients.

Objective To assess the short-time economics of various glutamine dipeptide-enriched parenteral nutrition (PN) for patients undergoing elective surgery for gastrointestinal tumors, with an attempt to provide evidence for decision makers on clinical nutrition support.Methods A prospective cohort study was designed.From payer/disburser''s perspective, a cost-effectiveness decision-tree model was developed to assess the clinical outcomes and short-time economic effects of glutamine dipeptide-enriched PN that used in different time points (early postoperative or perioperative).Cost-effectiveness analysis, cost-utility analysis, and incremental cost-effectiveness analysis were adopted in the decision-tree model.One-way sensitivity analysis was performed to determine the robustness of the results.Results Totally 107 patients were included.There was no significant difference between the perioperative alanine(Ala) glutamine(Gln) nutrition support (group A) and early postoperative Ala-Gln nutrition support (group B) in the ratio of 5％ weight declines on the 8th day after surgery and infection-related postoperative complications (72.1％ vs.78.1％, χ2=0.509, P=0.498 and 2.32％ vs.4.69％, χ2=0.060, P=0.806).The levels of prealbumin (PA) and albumin(Alb) and the level of total lymphocyte count(TLC) also the time of recovering gastrointestinal function, length of stay nutritional discharge index(LOSNDI), and direct costs were significantly different [PA:(208.19±56.92)mg/L vs.(187.97±62.05)mg/L, t=2.283,P=0.039;Alb:(33.82±3.91)×109 vs.(31.96±4.57)×109, t=2.184, P=0.036;TLC:(1.19±0.55)×109 vs.(0.89±0.66)×109, t=2.461, P=0.015;the time of recovering gastrointestinal function(3.06±0.28)d vs.(3.39 ± 0.34)d, t=-3.675, P=0.000;LOSNDI:(16.84±2.92)d vs.(18.52 ±3.47)d, t=-2.613, P=0.011;direct costs:￥(17 029.05±317.28) vs.￥(15 610.64±292.56), t=23.764, P=0.000].When LOSNDI and quality-adjusted life years (QALYs) were estimated as indicators of effectiveness, the incremental cost-effectiveness ratios and incremental cost-utility ratios of group A were ￥844.3 and ￥70 920.5, respectively.Net monetary benefit of group B was more than that of group A.One-way sensitivity analysis showed that parameters had no significant effect on the model.Conclusion When using local per capita gross domestic product as threshold, early postoperative Ala-Gln PN was more economical than perioperative Ala-Gln PN strategy evaluation.

Objective To investigate the effect of ionizing radiation on the invasion of the pulmonary adenocarcinoma cell line A549.Methods The invasiveness of A549 cells irradiated with 2 and 4 Gy doses of γ-rays was detected by using transwell invasion assay.The expression levels of matrix metalloproteinase (MMP)-2 mRNA and protein and phosphorylated signal transducers and activators of transcription 3 ( STAT3 ) protein were detected by reverse transcription PCR and Western blot.Results After irradiation with 2 or 4 Gy, the invasiveness of A549 cells increased by 200.0% ( F = 111.7, P ＜ 0.01 ) and 390.9% ( F = 593.7, P ＜ 0.01 ), respectively, compared with that in untreated A549 cells.Furthermore, the transcription and protein expression of MMP-2 24 h after irradiation and the phosphorylation of STAT3 12 h after irradiation were promoted.The irradiation-induced elevation of MMP-2 protein expression was suppressed using STAT3 phosphorylation specific inhibitor (AG490).Moreover,compared with 4 Gy of irradiation alone, treatment with 4 Gy of irradiation plus AG490 decreased the number of invasive cells by 76.1% ( F = 555.9, P ＜ 0.01 ), and the number of invasive cells in 4 Gy of irradiation plus AG490 group made up only 117.8% of that in untreated group ( F = 3.6, P ＞ 0.05 ).Conclusions Ionizing radiation could activate STAT3, which triggers the transcription of MMP-2, and then promote the invasiveness of A549 cells.

Objective To investigate the clinical value of early endoscopic intervention in diagnosis and treatment of acute nonvariceal upper gastrointestinal bleeding (ANVUGIB). Methods A retrospective analysis was performed of 150 senile patients with ANVUGIB who were intervened by early endoscopy or selective endoscopy from Janurary 2015 to September 2015. The causes of ANVUGIB were analyzed. The diagnosis rates, success rates of hemostasis, rates of rebleeding, surgery, hemostatic time, blood transfusion volume, hospitalization time, hospitalization cost were compared in early endoscopy group and selective endoscopy group. The quality of life was compared between the two groups by NHP after the patients left hospital for three months. Results Peptic ulcer, gastric cancer, acute hemor-rhagic gastritis were the three major causes of ANVUGIB. The diagnosis rate and successful hemostasis rates of early endoscopy group were significantly higher than that in selective endoscopy group ( < 0.05). The rates of rebleeding and surgery were significantly lower, the blood transfusion volume was reduced, hospitalization time were shorten, and hospitalization cost were lower in early endoscopy group ( < 0.05). The quality of life of early endoscopy group was statistically higher than that in selective endoscopy group ( < 0.05). Conclusion Early endoscopic intervention is safe, effective and identify hemorrhage cause fast in diagnosis and treatment in senile patients with ANVUGIB. It is worthy of widespread promoting.
