Objective To analyze the effect of clinical pathway management for capillary bronchitis in Department of Pediatrics.Methods 75 children with capillary bronchitis after the implementation of clinical pathway management were selected as the observation group,and 68 children with capillary bronchitis before the implementa-tion of clinical pathway management were selected as the control group.The hospitalization cost,average hospital stay, antibiotic use rate,cure rate,nonsocomial infection rate,rehospitalization rate within two weeks,service satisfaction and other comprehensive indices were compared.Result The total cost of drug of the observation group[(1 198.49 ± 397.48)yuan]was lower than (1 324.05 ±376.57)yuan of the control group(Z =2.00,P <0.05).The average hospital stay of the observation group[(6.99 ±2.39)d]was shorter than (8.01 ±2.22)d of the control group(Z =2.62,P <0.05).The service satisfaction rate of the observation group(95%)was higher than 82% of the control group(χ2 =5.44,P <0.05).The antimicrobial use rate of the observation group(49%)was apparently lower than 95% of the control group (χ2 =27.59,P <0.01).There were no statistically significant differences between the two groups in cure rate(hospital discharge rate),nosocomial infection rate and rehospitalization rate within two weeks(all P >0.05).Conclusion Clinical pathway management for capillary bronchitis in Department of Pediatrics of primary hospital can play a role in standardizing medical practice,reducing average hospitalization days,controlling medical cost,and improving service satisfaction under the precondition of ensuring medical quality.

Mild traumatic brain injury (MTBI) is defined as a mild brain trauma resulting in a short loss of consciousness and alteration of mental status. It may also occasionally develop persistent and pro-gressive symptoms. It has been confirmed that MTBI causes changes of anatomic structures in central nervous systemand biomarkers in the body fluid. How ever, there is no sufficient research on relevance among threshold for the brain injury, individual vulnerability and duration of disturbance of conscious-ness. Furthermore, there are no reliable diagnostic methods to establish w hether a blow to the head is sufficient to cause the brain injury. T his review provides references for biomarkers in cerebrospinal fluid and blood associated w ith T B I. It also provides application status and potential prospects for further as-sessment and diagnosis of MTBI.

Objective To investigate the influence of synergistic effect of estradiol and testosterone on the level of lipids and coagulation function in mice with hyperlipidemia .Methods We established a maouse model in hyperlipidmia , giving estradiol (1 μg/d), testosterone (7 μg/d) or estradiol combined testosterone (1 μg/d E2 +7Tμg/d), respectively.After 14 weeks, we collected the blood from the mice , separated the serum to detect the lipids level , separated the plasma to test the coagulation function .Result Compared with controls , after high-fat diet , the serum level of total cholesterol ( TC) , triglyceride ( TG) , high density lipoprotein ( HDL) were significantly increased , PT and APTT were shorter ( P<0.05 ).However, after treating with estradiol combined testosterone , compared with cases, the serum level of C, TG and HDL were lower and PT , APTT were longer ( P <0.05 ), had no significance with controls . Conclusion The synergistic effect of estradiol and testosterone can mediate the lipids , reduce the level of LDL , regulate the coagulation function , reduce the risk of coronary heart disease , and also provide a new strategy for hormone therapy in coronary heart disease .

Objective: To identify the related psychosocial risk factors of emotional disorders in children. Methods:To use case-control approach in which. Diagnosis was made by clinical interview according to ICD-10 criteria. Eighty eight cases and controls separately filled out general condition inventory. The results were put into Logistic regression model for analysis. Results: The children with timid personality, without kindergarten education, or with parents who were administrative or technical personnel, were apt to have emotional disorders. The children who were usually counseled by their mothers had less emotional disorders than those were beaten. Conclusion: The emotional disorders were the results of multiple factors. Prevention of children's emotional disorders should be focused on the children's personality and family education.

Objective To evaluate operative methods and the clinical effect for comminuted calcaneal fractures.Methods 21 cases(24 feet)of comminuted calcaneal fractures were treated by one stage bone grafting plus open reduction and internal fixation with plastic calcaneus titanium plate.The fractures were classified according to the Sanders system into Sanders Ⅱ,Ⅲ and Ⅳ subgroups.Results All cases were followed up for 9～20 months(14months in average).All cases recovered with good healing of fracture.According to Maryland score,the results were excellent in 14 feet,good in 7 feet,fair in 2 feet,and poor in 1 foot.The excellent and good rate was 87.5％.Conclusions By using the method of internal fixation with plastic calcaneus titanium plate,fracture site can be well exposed,which is helpful to recover calcaneus to its normal length,width,height,Gissane angle and Bohler angle.A reliable internal fixation is helpful for early stage functional excise after surgery,which can maximize the recovery of the ankle function.

Objective To investigate the incidence of cholecystolithiasis in 1iver cirrhosis and analyze its influencing factors and clinical significance. Methods We selected 128 patients with 1iver cirrhosis who were di-agnosed and treated in the First Affiliated Hospital of Henan University of Science and Technology from Oct. 2014 to Aug. 2015 as the observation group. Meanwhile, 140 cases received medical examination served as the control group. The liver cirrhosis group were divided into class A (group A), class B (group B), class C (group C) ac-cording to the Child-Pugh grades. We measured the levels of fasting serum albumin (ALB) and cholecystokinin (CCK) of all subjects. The relationship of cholecystolithiasis in 1iver cirrhosis to gender, liver function Child-Pugh classification, ascites, levels of ALB and CCK was analyzed. Results (1) Univariate analysis revealed: compared with the control group, the incidence of cholecystolithiasis in 1iver cirrhosis group was higher (35.2%vs 8.6%, P<0.05). With increase of the degree of liver damage, the incidence of cholecystolithiasis increased. And the incidence of cholecystolithiasis in group B and group C were both higher than that of group A (group A 22.9% vs group B 35.0%vs group C 50.0%, P<0.05). The incidence of cholecystolithiasis in the 1iver cirrhosis group with ascites was significantly higher than that of the control group (38.6% vs 22.2% vs 8.6%, P < 0.05). With increase of the degree of liver damage, the level of ALB in liver cirrhosis group decreased compared with the control group (P<0.05), while the level of CCK was obviously higher than that of the control group (P < 0.05). The morbidity rate did not differ between the males and females with cirrhosis (P>0.05). (2) Multiple Logistic regression analysis re-vealed that the level of ALB is the main influencing factor (P<0.05). Other factors were not statistically significant. Conclusion Cholecystolithiasis frequently occurs in patients with liver cirrhosis, which has no correlation with the gender of patient, but it correlates with liver function, ascites, the levels of ALB and CCK. Among of them, the level of ALB is the main influencing factor.

AIM:To explore the ability of different group B streptococci ( GBS) strains on inducing platelet activation.METHODS:Six strains of GBS, separated from the septic patients with thrombocytopenia, were used as the inducers.Light transmission aggregometry was used to measure platelet aggregation.Scanning electron microscopy ( SEM) was performed to investigate the interaction of platelets with bacteria.The expression of platelet CD62P, Toll-like receptor 2 ( TLR2) and TLR4 was determined by flow cytometry and Western blotting.Furthermore, the activity of platelet TLR2 (or TLR4) was blocked by anti-TLR2 (or anti-TLR4) monoclonal antibody, and the platelet aggregation induced by GBS was detected.RESULTS:Only 3 of 6 GBS strains isolated from the septic patients induced platelet aggregation and up-regulated the expression of CD62P and TLR2 in the platelets (P<0.05), but not TLR4.Incubation with anti-TLR2 anti-body, but not anti-TLR4 antibody, significantly blocked platelet aggregation induced by GBS.CONCLUSION:Some GBS strains from the patients are able to trigger platelet activation in vitro, and platelet TLR2 may play an important role in the interaction between GBS and platelets.

AIM: To investigate the effects of in situ transplantation of mobilized autologous bone marrow stem cells on infarction size and cardiac function in patients with acute myocardial infarction. METHODS:25 patients with first acute myocardial infarction were randomly divided into stem cells in situ transplantation group and control group, 12 patients in stem cells in situ transplantation group were injected subcutaneously with 300 ?g granulocyte colony-stimulating factor(G-CSF) daily for four days in addition to standard therapy. 13 patients in control group were treated with standard therapy alone. The conventional 12 leads electrocardiogram were recorded on 1, 28 days after admission and the cardiac function was scored by the QRS scoring system proposed by Wagner. Furthermore, the infarction size was assessed by radionuclide myocardial perfusion imaging 7, 28 days after admission. RESULTS:4 weeks after admission, the QRS scores decreased, the infarction size reduced significantly in the stem cells in situ transplantation group (from 36.0%?8.3% to 18.0%?5.8%, P
