OBJECTIVE:To evaluate the clinical effect of Dahuang zhechong pill on chronic hepatitis with hepatic fibrosis.METHODS:A total of 128 patients with chronic hepatitis with hepatic fibrosis were randomly divided into treatment group(68 cases) and control group(60 cases).The control group received routine hepatic protective therapy,while the treatment group received routine hepatic protective therapy and Dahuang zhechong pills(6 g?d-1) concomitantly.The course of treatment lasted for 6 months.The clinical symptoms,liver function,hyaluronic acid(HA),pro-collagen Ⅲ(PC Ⅲ),cholyglycine(CG) and collagen type Ⅳ(ⅣC),and ultrasound image were observed in both groups.RESULTS:Levels of serum HA,PCⅢ,CG,and ⅣC decreased significantly in treatment group,and the difference between two groups was significant(P

Objective To explore the relationship of suicide ideation, depression and meaning in life as well as the effect of meaning in life between depression and suicide ideation.Methods Beck Scale for Suicide Ideation(BSI-CV) , Purpose in Life test (PIL) and Self-Rating Depression scale (DSD) were employed to investigate 1 688 freshmen.Results Suicide ideation had significant positive correlation with depression(r=0.326, P＜0.01;r=0.3, P＜0.01) ,while it had significant negative correlation with meaning in life(r=-0.34, P＜0.01;r=-0.37, P＜0.01).Depression of freshmen with suicide ideation was higher than ones without((48.04±8.13) vs (44.56±7.12), P＜0.01), and meaning in life of freshmen with suicide ideation was lower than ones without ((98.39±12.68) vs (105.78± 11.76), P＜0.01).Meaning in life partially mediated the relationship between depression and suicide ideation.Conclusion Suicide ideation of college freshmen are related to depression and meaning in life, and meaning in life can partially mediated the relationship between depression and suicide ideation.

Objective To investigate the clinical results and related key points of surgical treatment for Hawkins Ⅲ talus neck fractures.Methods Forty-one patients with Hawkins Ⅲ talus neck fracture were treated.The fractures occurred on the left side in 21 patients and on the right side in 20 patients.All patients were performed internal fixation by internal and lateral approaches.The weight bearing should be adjusted with follow-up.The functional results were evaluated by American Orthopaedic Foot and Ankle Society (AOFAS).Results The average duration of follow-up was (37.7 ± 8.2) months.All fractures gained union and the average union time was (4.1 ±0.5) months.The average AOFAS score after treatment was (79.3 ± 2.6) scores which was higher than that before treatment [(35.1 ± 8.0) scores],and there was significant difference (P =0.026).There were 11 cases in excellent,17 cases in good,11 cases in fair and 2 cases in poor.The excellent and good rate was 68.3％ (28/41).Traumatic arthritis occurred in 18 cases (43.9％,18/41),involved tibial astragaloid joint in 4 cases,involved subtalar joint in 6 cases,involved tibial astragaloid joint and subtalar joint in 8 cases.Avascular necrosis occurred in 7 cases (17.1％,7/41).Conclusions The effect of surgical treatment for Hawkins Ⅲ talus neck fracture via a bilateral approaches is satisfactory.Pay more attention to protect blood circulation intraoperative and perform anatomic reduction according to the characteristic of body of talus displacement.After operation,functional rehabilitation should be directed by the principle of early movement,later weighted.

IEEE Std 1708-2014 breaks through the traditional standards of cuff based blood pressure measuring devices and establishes a normative definition of wearable cuffless blood pressure measuring devices and the objective performance evaluation of this kind of devices. This study firstly introduces the background of the new standard. Then, the standard details will be described, and the impact of cuffless blood pressure measuring devices with the new standard on manufacturers and end users will be addressed.

Objective To discusse the expression and clinic opathologic significance of vascular endothelial growth factor(VEGF) and microvessel density(MVD) in primary liver cancer,an immunohistochemical staining.Methods The expressions of VEGF and Ⅷ factor were determined in 60 selected operation specimen from patients with primary liver carcinoma.Results It showed that the positive expression rate of VEGF in primary liver cancer was 63.3%,the MVD was (30.76?11.56).Among them,the MVD in positive VEGF expression was (46.37?15.85),and the MVD in negative expression was (18.97?8.68),there were great statistical difference between them(P0.05).Conclusion This study indicates that VEGF can facilitate the formation of microvessel of the tumor and has correlation with the growth,infiltration and metastasis of primary liver cancer.

OBJECTIVE:To observe the effect of intravenous administration of amiodarone on postoperative heart failure and ventricular arrhythmia.METHODS:A total of 42 postoperative heart failure patients with ventricular tachycardia and multi-source ventricular premature beat were treated with lidocaine,but clinical efficacy was not obtained.Those patients received intravenous administration of diluted amiodarome 150 mg.After 30 minutes the dose of amiodarone was kept at 0.5～1.0 mg?min-1,and the total dosage ranged from 1 000 mg to 1 200 mg within 24 h.Clinical symptoms were recorded in every hour,such as cardiac rhythm,heart rate,blood pressure,heart failure.RESULTS:After 24 h of treatment,17 cases of ventricular arrhythmia had apparent effect(40%),20 cases of partial effect(47%),5 cases of no effect(12%),there were statistical significance in difference before and after treatment(P

Objective To apply the theory basis for effectively preventing and treating rotavirus infection by studying on specific humoral immune response in children with rotavirus diarrhea. Methods Seventy-five patients of children (diarrhea group ) and 45 controls (control group) were selected. The antigen and specific antibody in plasma and stool were detected by ELISA method;the type of viral gene was confirmed by reverse transcription PCR method;the expression of mRNA in peripheral blood mononuclear cell was measured by fluorescent light quantitation PCR method. Results In diarrhea group, rotavirus G typing to G3 dominated, accounting for 77.3% (58/75), P sub-type to P8 mainly, accounting for 82.7% (62/75). Rotavirus-specific antibody titers of plasma in diarrhea group were significantly higher than those in control group, IgA antibody titers of stool increased significantly, not only higher than that in control group and plasma. The percentage of CD19+ cells in diarrhea group [(30.8 ± 7.9)%] was significantly higher than that in control group [(23.1 ± 7.7 )%] (P = 0.009 ). And the proportion of CD4+ cells decreased significantly (P = 0.005 ), the expression level of IL- 12p40 mRNA in the entire process in diarrhea group was significantly higher than that in control group(P＜ 0.01 ). Conclusion Children with acute rotavirus infection early in the immune response to specific humoral immunity, especially mucosal immune to significantly improve the main features.

To study the expression of the bFGF and its receptor in the mouse bone marrow by treatment with acute radioactive injury and Ligustrazine, 56 mice were divided into 3 groups: normal group, radiation-injured group and Ligustrazine group. After irradiation by 6.0 Gy 60Co gamma-ray, each mouse was orally given 0.1 ml Ligustrazine twice a day for 13 days in Ligustrazine group, and each mouse in radiation injured group was orally given equal amount of saline. On the 3rd, 7th, 14th day after irradiation, bone marrow mono-nuclear cells (BMMNC) were counted, and the expression levels of bPGF and bFGFR in bone marrow were evaluated by immunohistochemistry and flow cytometry analysis respectively. On the 3rd, 7th, 14th day after irradiation, expression of bFGF in bone marrow were significantly lower than in normal group (P<0.05 or P<0.01). Expressions of bFGF and bFGFR were much higher in Ligustrazine treated group than that in the control group (P<0.05 or P<0.01). Ligustrazine potentiate the expression of bFGF and bFGFR in bone marrow MNC to recover the bone marrow hematopoiesis inductive microenvironment, which is one of the mechanisms by which Ligustrazine rebuild the bone marrow hematopoiesis after acute radioactive injury.
