Objective To investigate the relationship between serum adiponectin (APN) concentration and liver fibrosis in patients with chronic hepatitis B. Methods Sixty-three patients with chronic hepatitis B and liver fibrosis treat-ed in Department of Infectious Diseases of our hospital from January 2013 to June 2015 were studied, which were divided into mild group (n=28), severe group (n=22) and cirrhosis group (n=13) according to the degree of liver fibrosis. Thirty healthy volunteers were included into the control group. The serum APN concentration and haluronic acid (HA), laminin (LN), type Ⅲ procollagen (PC-Ⅲ), type Ⅳ collagen (C-Ⅳ) concentrations were detected in all the subjects. The index levels were detected and compared in patients with chronic hepatitis B before and after antiviral therapy. Results The se-rum APN concentration in the control group, mild group and severe group and cirrhosis group were increased successively, with (6.41±2.21)μg/mL, (9.46±3.27)μg/mL, (15.11±4.30)μg/mL, (20.54±5.52)μg/mL, respectively, and HA, LN, PC-Ⅲ, C-Ⅳalso increased in turn, with statistically significant differences (P<0.05). Serum APN concentration showed a pos-itive correlation with liver fibrosis grading (P<0.05). In liver fibrosis patients, the serum APN and HA, LN, PC-Ⅲ, C-Ⅳwere significantly lower after antiviral therapy, compared with those before treatment (P<0.05). Conclusion Adiponectin concentrations is closely related to the liver fibrosis in chronic hepatitis B process, and serum adiponectin concentrations can reflect the degree of liver fibrosis and improvement degree of liver fibrosis after anti-viral therapy.

Objective To investigate the distribution characteristics of TCM syndrome types in hand, foot and mouth disease and related influencing factors.Methods The clinical data of 298 children with hand, foot and mouth disease who were diagnosed with the four diagnostic methods in traditional Chinese medicine (TCM) were collected to analyze the distribution characteristics of TCM syndrome types and their association with sex, age, course of the disease, and major laboratory markers.Results In the 298 children with hand, foot and mouth disease, the most common TCM syndrome type was stagnation and steaming of damp-heat, followed by the syndrome of damp-heat of lung and spleen and the syndrome of stirring wind due to toxic heat.There were significant differences in sex and course of the disease between the children with the three syndrome types (P<0.05).The syndrome of stirring wind due to toxic heat was commonly seen in boys.The syndrome of damp-heat of lung and spleen was commonly seen at 5-6 days after onset, the syndrome of stagnation and steaming of damp-heat was commonly seen at 5-7 days after onset, and the syndrome of stirring wind due to toxic heat was commonly seen at 7-8 days after onset.There was no significant difference in age between the children with the three syndrome types (P>0.05).There was a significant difference in the type of pathogen between the children with the three syndrome types (P<0.05);the children with the syndrome of damp-heat of lung and spleen were mainly infected with coxsackie virus A-16, while those with the syndromes of stagnation and steaming of damp-heat and stirring wind due to toxic heat were mainly infected with enter ovirus 71.Compared with those with the syndromes of damp-heat of lung and spleen and stagnation and steaming of damp-heat, the children with the syndrome of stirring wind due to toxic heat had significantly higher leukocyte count and levels of blood glucose, creatine kinase-MB, serum interleukin-6, procalcitonin, and C-reactive protein (P<0.05).Conclusion The distribution of TCM syndrome types of hand, foot and mouth disease have certain characteristics, which are significantly associated with sex, course of the disease, and major laboratory markers.

Objective To discuss the clinical effects of PEG-IFN-αcombined with ribavirin in the treatment of chronic hepatitis C virus (HCV) and hepatitis B virus (HBV) coinfection. Methods Forty patients with HCV and HBV coinfection from TCM Hospital of Eastern Hubei Medical Group between April 2011 and December 2015 were divided into the HBV/HCV group, and 45 patients with HCV infection were divided into the HCV group. Then the two groups were treated with PEG-IFN-αcombined with ribavirin, and the clinical effects were contrasted between the two groups. Results The negative conversion rate after the treatment in the HCV group was 55.6%, significantly higher than 32.5%in the HBV/HCV group (P<0.05). Aspertate aminotransferase (AST), alanine transaminase (ALT), haluronic acid (HA) in the HCV group and ALT, AST in the HBV/HCV group after the treatment were significantly better than before treat-ment (P<0.05), and there was no significant difference in procollagen typeⅢ(PCⅢ) in the HCV group and PCⅢ, HA in the HBV/HCV group before and after the treatment (P>0.05). No significant difference was found in ALT, AST, HA, PCⅢbetween the two groups after the treatment (P>0.05). Conclusion PEG-IFN-αcombined with ribavirin has bet-ter clinical effects in the treatment of HCV or HBV single infection than coinfection.
