ABSTRACT
Objective:To evaluate the effectiveness and safety of butyl phthalide capsules combined with Xueshuantong injection in the treatment of acute cerebral infarction (ACI). Methods: Cochrane Library, Medline, Embase, SCI, CBM, CNKI, VIP and Wanfang databases were searched from the building time to May 2016. The enrolled randomized controlled trails were studied by using Cochrane system evaluation methods to perform methodological quality assessment, and RevMan 5. 2 software was used to carry out Me-ta-analysis. Results:A total of 7 randomized controlled trails including 640 patients were enrolled. The results of Meta-analysis dem-onstrated that the effective rate of butylphthalide capsules combined with Xueshuantong injection was superior to that of Xueshuantong injection (RR=1. 33, 95%CI:1. 16-1. 52, P<0. 0001), butylphthalide (RR=1. 45, 95%CI:1. 15-1. 83, P=0. 002) and blank control (RR=1. 31, 95%CI:1. 08-1. 57, P=0. 005). NHISS of butylphthalide capsules combined with Xueshuantong injection was higher than that of Xueshuantong injection (MD=4. 63, 95%CI:3. 38-5. 87, P<0. 00001) and blank control (MD=6. 85, 95%CI:4. 90-8. 80, P<0. 00001). There was no significant difference in adverse drug reactions. Conclusion: Butylphthalide capsules combined with Xueshuantong injection is effective for the therapy of ACI. However, due to the limited quantity and quality of the in-cluded studies, larger scale trials are needed.
ABSTRACT
Objective To evaluate the feasibility of the three-dimensional brain artery vessel wall imaging technology reverse rotation angle of fast spin echo (T1 W-SPACE)in the diagnosis of ischemic cerebrovascular disease by comparing it with TOF vascular imaging in magnetic resonance. Methods Patients undergoing stroke but stable condition,including 50,patients with transient cerebral ischemia (TIA)or a history of stroke,examined by TOF-MRA and routine MRI sequence first,then followed by T1 W-SPACE.Results In 43 of 50 cases,conventional MRI sequences detectiog was positive,TOF-MRA found the vascular stenosis in 76 branches,T1 W-SPACE found the vascular stenosis in 73 branches,there was no difference between the two groups(χ2 =0.625,P >0.05);Conventional TOF-MRA cannot detect the vascular wall, T1 W-SPACE found that arterial wall thickening,plaque in 48 branches.Conclusion Compared with the TOF-MRA,T1 W-SPACE can not only detect the vessel stenosis,but also the vessel wall and plaque,and can also type on plaque from pathology angle,has im-portant clinical significance for early prevention and treatment of stroke.

ABSTRACT
Objective To evaluate the impact of hepatitis B e antigen (HBeAg) states and hepatitis B virus DNA loads on the prognosis of chronic severe hepatitis B.Methods A total of 406 hospitalized patients with chronic severe hepatitis B in Nanfang Hospital of Southern Medical University from January 2002 to December 2007 were retrospectively analyzed.The impact of HBeAg states and HBV DNA loads on the prognosis was evaluated.The measurement data were compared by t test and rates were compared by chi square test.Results Of all the 406 patients with chronic severe hepatitis B,208 (51.2%) patients were HBeAg-positive and the remaining 198 (48.8%) were HBeAgnegative.There was no significant difference of constituent ratio of male and female,average peak value of total bilirubin and average valley value of prothrombin activity between HBeAg-positive group and HBeAgnegative group.However,the average age of HBeAg-negative patients was (46.7±12.8) years old,which was significantly higher than that (38.3±13.5) years old in HBeAg-positive group (t = 6.43,P<0.01 )the proportion of patients with liver cirrhosis in HBeAg-negative group (67.7%) was much higher than that in HBeAg-positive group (45.7%) (X2=19.97,P<0.01);the improved rate in HBeAg-negative group (32.3%) was significant lower than that in HBcAg-positive group (44.7%) (X2=6.56,P<0.05).Increasing HBV DNA levels was associated with lower improved rate in both 208 HBeAg-positive and 198 HBeAg-negative patients(X2=22.98,26.04,respectively,both P<0.01 ).Conclusions HBeAg-negative patients with chronic severe hepatitis B has worse prognosis than HBeAg-positive patients;and the prognosis is getting worse with the increasing HBV DNA level regardless of the HBeAg status.
ABSTRACT
Objective To investigate the efficacy of individualized interferon (IFN)-alpha therapy in HBeAg-negative chronic hepatitis B patients. Methods Seventy- six Chinese HBeAg-negative chronic hepatitis B patients proven by liver biopsy were treated with 5 MU recombinant IFN-alpha 1b subcutaneously thrice every week. All the patients were followed up for at least 24 months the combined responses were defined as normalization of serum alanine transaminase (ALT) and HBV DNA<3 log10 copy/mL. An intention-to-treat (ITT) analysis was used in this paper in which all 76 patients were included. Results Six patients were lost. Treatment duration was in the range 2-24 months with a median of 8.5 months, and combined responses were achieved at a median of 6.0 months (range 2-19 months) of treatment duration.Seventy-five-percentile of treatment duration to endpoints was 10.0 months. The combined response rate was 46.1% (35/76) at the end of treatment, 43.3% (33/76) at 12-month follow-up and 40.8% (31/76) at 24-month follow-up. The relapse rate was 20. 0% (7/35) and 25. 7% (9/35) at 12-month and 24-month follow-up, respectively. Higher necroinflammatory activity in liver biopsy predicted a good response, while gender, age, liver fibrosis, baseline ALT, aspartate aminotransferase levels and baseline HBV DNA levels were not impact factors of therapeutic effects by binary Logistic regression analysis.Conclusion Individualized prolonged IFN-alpha regimen lead to considerable sustained disease suppression in patients with HBeAg-negative chronic hepatitis B.
ABSTRACT
<p><b>OBJECTIVE</b>To discuss the diagnostic value of ultrasonic examination in patients with early liver cirrhosis and the relation with different stages of liver fibrosis.</p><p><b>METHODS</b>In the series, 263 patients with chronic hepatitis B were under taken liver biopsy and ultrasonic examination of type B for determination of liver cirrhosis images, width of the main portal vein and the splenic vein, tumefaction of the spleen. Data were analysed statistically.</p><p><b>RESULTS</b>Sixties of 263 patients were diagnosed as early liver cirrhosis. The diagnostic sensitivity, specificity, misdiagnostic rate, missed diagnostic rate, and Jonden's index of ultrasonic examination for early liver cirrhosis were 52.5%, 88.3%, 11.7%, 47.5%, and 0.508, respectively. The width of the main portal vein with liver fibrosis of S1, S2, S3, and S4 were 10.93 mm +/- 1.25 mm, 11.35 mm +/- 1.06 mm,11.29 mm +/- 1.52 mm, and 11.4 8mm +/- 1.25 mm, respectively with statistic difference between S4 and S1 (P=0.03). The width of the spleen vein of S1, S2, S3, and S4 were 6.518 mm +/- 2.033 mm, 7.190 mm +/- 1.569 mm, 7.444 mm +/- 1.805 mm and 8.406 mm +/- 2.227 mm, respectively with statistic difference between S4 and S2 (P=0.035). The incidence of tumefaction of the spleen was increased with the degree of liver fibrosis.</p><p><b>CONCLUSIONS</b>The diagnostic sensitivity of ultrasonic examination for early liver cirrhosis is low. The width of the main portal vein, the spleen vein and the incidence of tumefaction of the spleen are related with the degree of liver fibrosis. The regeneration node of liver cirrhosis may contribute to the development of portal hypertension.</p>

<p><b>OBJECTIVE</b>To investigate the compositions of Th1/Th2/Th3 cells in chronic hepatitis B virus (HBV)-infected individuals by determining the expression of interleukin-4 (IL-4), inetrferon-gamma (IFN-gamma), and transform growth factor-beta (TGF-beta) in single CD4(+) T cells isolated from peripheral blood mononuclear cells (PBMCs) and the role of polarized Th cell populations in chronic HBV-infection was discussed.</p><p><b>METHODS</b>PBMCs from chronically infected HBV individuals were isolated, stimulated by PMA/Ionomycin/Monensin, and IL-4, IFN-gamma and TGF-beta production by CD4(+) T cells was determined by using fluorescence activated cell sorter (FACS) analysis.</p><p><b>RESULTS</b>The percentage of IFN-gamma-producing T cells, IL-4-producing T cells and TGF-beta-producing T cells ranged from 2.3% - 18.6%, 1.1% - 8.7% and 0.7% - 7.1% respectively in CD4(+) T cells from non-infected individuals. Most of CD4(+) T cells from PBMCs in chronically infected HBV individuals were Th0 cells. The proportion of Th1 cells increased significantly with hepatic inflammatory activity, and in the active period of chronic hepatitis B infection were higher than those in the non-active period (P < 0.05). Th2 cell percentage in CD4(+) T cells from HBV-infected individuals did not differ significantly (P > 0.05), but were higher than that from controls (P < 0.05). Th3 cell percentage in CD4(+) T cells from asymptomatic carrier (AsC) group was higher than that in the chronic hepatitis B (CHB) and control groups (P < 0.05).</p><p><b>CONCLUSIONS</b>Th1 phenotype cytokines were positively correlated with hepatic inflammatory activity in chronic hepatitis B and Th2 cells may be associated with the persistence of HBV infection. Th3 cells cooperating with Th2 cells can negatively regulate immune responses and may be associated with the immune tolerant state of chronic HBV infection.</p>
