Objective To compare methimazole and propylthiouracil affecting liver function by treating hyperthyroidism.Methods Total 80 patients with hyperthyroidism were randomly divided into two groups.Group A (41 cases) was given methimazole,group B (39 cases) was given propylthiouracil.The effect of methimazole and propylthiouracil affecting liver function by treating hyperthyroidism was evaluated by the indexes of thyroid function,liver function,liver damage,and adverse reaction during treatment.Results Before treatment,there were no statistical significance on FT3 and FT4 between two groups.After treatment,the FT3and FT4 were decreased and TSH was increased in two groups (P ＜ 0.05).But there were no statistical significance between two groups.Before treatment,there was no statistical significance on ALT,AST,and GGT between two groups.After treatment,the ALT,AST,and GGT increased in group B and higher than that of group A (P ＜ 0.05).The ALT,AST,and GGT had no change before and after treatment in the group A.During treatment,there were five cases of liver injury in group A and 14 cases in group B.The liver injury rate of group B was higher than that of group A (P ＜ 0.05) and injury time of group B was later than that of group A.During treatment,there was no statistical significance on adverse reaction rate between two groups.Conclusion The efficacy of methimazole was equal to propylthiouracil in treating hyperthyroidism.Compared with propylthiouracil,the methimazole had less injury on liver but induce the liver injury in earlier.It is suggested that the patients should check the liver function regularly during treatment.

BACKGROUND:Fibrin glue has been widely used in breast surgery, but due to the limitation of cases, there are some differences in clinical effects.
OBJECTIVE:To systemicaly review the clinical effect of fibrin glue in breast surgery.
METHODS: We searched China Journal Ful-text Database (CNKI), VIP database, Wanfang Database for clinical randomized controled trials related to fibrin glue used in breast surgery published from March 2002 to March 2014. A Meta-analysis was done in included studies using Rev Man 5.2 statistical software.
RESULTS AND CONCLUSION:A total of 11 studies, with 1 043 cases, were enroled for the Meta-analysis. Meta-analysis showed that the postoperative 1-day drainage amount and total drainage amount were significantly lower in the fibrin glue group than the control group [WMD=-85.62, 95%CI(-128.86,-42.39), P=0.000 1;WMD=-167.27, 95%CI (-210.05,-124.49),P < 0.000 01]. In addition, the fibrin glue group was superior to the control group in the postoperative seroma rate [OR=0.30, 95%CI (0.21, 0.44),P< 0.000 01]. Application of fibrin glue in breast cancer surgery can significantly reduce postoperative drainage and seroma rate.

This article described that the biology and medicine research is an important field in the international cooperation of science and technology.Meantime,by analysis on the achievements of the international cooperation from 2005 in Chinese Academy of Medical Sciences.it was shown that the intemational cooperation plays very important rule in promoting the research development in the biological and medical field.Also some principles of the international cooperation of science and technology were put forward in this article.

Objective:To analyze the clinical characteristics and laboratory examinations of hospitalized children with influenza, and improve medical personal awareness of severe influenza.Methods:Data of inpatients with influenza from November 2018 to February 2019 at Shenzhen Children′s Hospital was collected, and the clinical characteristics and laboratory examinations were statistical analyzed.Results:Of the 702 cases, 464(66.1%) cases were mild influenza, and 238 cases(33.9%)were severe influenza; the median age was 3.8 years, and 457(65.1%) cases were 0 to 5 years old.The number of patients with basic diseases and wheezing symptoms in the severe group was more than those in the mild group, with statistically significant differences(all P<0.05). The white blood cell count, percentage of neutrophils, neutrophils to lymphocytes ratio(NLR), C-reactive protein and procalcitonin in the severe group were higher than those in the mild group, while the percentage of lymphocytes was lower than that in the mild group(all P<0.05). Logistic multivariate regression analysis showed that underlying diseases, wheezing and NLR were risk factors for severe influenza.The area under the curve of NLR for severe influenza was 0.574, whose best cutoff value was 1.43. Conclusion:Influenza virus infection among children is mainly influenza A, and mostly affected children are under 5 years old.The blood routine of children with severe influenza mostly showes increased white blood cell, mainly neutrophils increased significantly, and increased C-reactive protein and procalcitonin.Children with underlying diseases, wheezing symptoms during the course of the disease, and elevated NLR are more likely to progress to severe cases, and NLR cannot be used as a independent predictor of severe influenza.

miRNAs are a group of 22 ~25 nucleotides endogenous non-coding RNAs,which regulate gene expression at the post-transcription level by cause the degradation or translational suppression of target mR-NAs.In recent years,studies have demonstrated that miRNAs widely participate in cell differentiation,prolifera-tion,organ development and lipid metabolism,and are closely related to the formation of many kinds of diseases. The biological function of miRNAs and their effects on regulating prenatal and postnatal lung development are reviewed in this paper.

Objective To explore clinical effect of modified postural drainage for treating pulmonary infection of senile patients with gastric cancer.Methods 107 cases of patients with gastric cancer were randomly divided into two groups:control group (n =53) and treatment group (n =54),which were respectively treated by routine postoperative therapy and nursing measures and modified postural drainage based on these routine measures,and compared daily amount of expectoration sputum,positive cases of sputum culture,restore time of postoperative blood test,postoperative fever time,cases of pulmonary infection on the postoperative tenth day and length of stay.Results Daily amount of expectoration sputum of patients in treatment group was significantly higher than that of control group [(185.7 ± 23.7) ml vs.(99.7 ± 17.6) ml] (P ＜ 0.05).However,restore time of postoperative characters of blood test [white blood cell count (2.9±0.9) d vs (5.0±0.7)d,C-reaction protein (35±0.7)d vs.(7.4±0.6) d],postoperative fever time [(1.9±0.5) d vs.(3.6±1.4) d],cases of atelectasis (5 cases vs.19 cases) and length of stay [(1.9±0.5) d vs.(3.6±1.4) d] were respectively significantly less than those of control group (P ＜ 0.05).Conclusions Modified postural drainage could effectively prevent postoperative atelectasis and pulmonary infection,significantly reduced incidence of postoperative atelectasis of senile patients with gastric cancer operation,and so it was worthy of clinical application.

Objective To investigate the clinicopathological relation between the TNF-? and IgA nephropathy. Methods TNF-? levels in serum, urine and renal tissues of 50 patients with IgA nephropathy were measured, and 10 patients with minimal change nephrotic syndrome(MCNS) and 10 healthy subjects served as negative control group. Results The serum and urine levels of TNF-? in the patients with IgA nephropathy were significantly higher than those in the patients with MCNS and healthy subjects, and had a significant positive correlation with the degree of proteinuria and renal demage. TNF-? expression was mainly localized in the cytoplasm of the proximal renal tubular epithelial cells, and the interstitium with more monocyte-macrophages infiltration. Conclusion TNF-? took part in the onset of hematuria and proteinuria, was correlated with the degree of renal damage, and played an important role in the aggravation of IgA nephropathy.

Tissue factor is a powerful promoter of blood clotting in vivo , it plays an important role In hematischesis, tissue repair and thrombogenesis. In recent years, it is discovered that tissue factor can discriminate and regulate cell signal transduction, promote neogenesis of blood vessel and inflammatory reaction, regulate cell adhesion and movement, have a intimate relationship with invasion and metastasis of malignant tumor. In this article, we review the effects of tissue factor on malignant tumor metastasis.
