Relationship between the expression of SOCS-1/3 in the peripheral blood mononuclear cells and interferon therapeutic response in patients with chronic hepatitis B / 中国基层医药

Objective To investigate the relationship between the the expression of SOCS-1/3 in the peripheral blood mononuclear cells (PBMCs) and interferon therapeutic response in patients with chronic hepatitis B.Methods 50 patients with chronic hepatitis B were given interferon therapy.After 24 weeks treatment,according to biochemical and virologic response,they were divided into two groups:response and non response group.HBV-DNA was detected by PCR.The SOCS-1/3 mRNA levels were measured by RT-PCR.Results The expression of SOCS-1 in the PBMCs of response group after 24 weeks treatment was significantly higher than that before interferon therapy (P ＜ 0.05).The expression of SOCS-3 in the PBMCs of response group after 24 weeks trentment was significantly lower than that before interferon therapy (P ＜ 0.05).In non response group,there were no significant differences in the expression of SOCS-1/3 (P ＞ 0.05).Conclusion The increase expression of SOCS-1 mRNA and the decrease of SOCS-3 mRNA in the PBMCs in chronic hepatitis B patients received 24 weeks interferon-therapy probably is relevant to the IFN-α antiviral effect.

Relationship between the serum chemokine IP-10 and RANTES levels and Interferon therapeutic early response in patients with chronic hepatitis B / 中国基层医药

Objective To investigate the relationship between the serum chemokine IP-10 and RANTES levels and Interferon therapeutic early response in patients with chronic hepatitis B(CHB).Methods 50 patients with chronic hepatitis B were chosen into interferon therapy.After 12 weeks,they were devided into three groups:complete response A、partial response B、non response C group.HBV-DNA was detected by PCR;The serum chemokines( IP-10 and RANTES) were measured by Luminex Liquichip technology.Results The base HBV DNA and RANTES levels of three groups weren't significantly different (P ＜0.05) ;The base ALT and IP-10 levels of A group were significantly higher than that in B and C group( P ＜ 0.05).The IP-10、RANTES contents of A group in therapeutic 4th week were significantly lower than that before interferon therapy(P ＜ 0.05 );There were no significant differences in B、C group (P ＞0.05) ;The levels changes of IP-10、RANTES、HBV DNA and ALT in therapeutic 12th week were significantly different between the three groups ( P ＜ 0.05 ),The level of ALT in 50 patients has positive correlation with IP-10 level (P ＜ 0.05) ;The level of HBV DNA in 50 patients had positive correlation with RANTES level( P ＜ 0.05 ) ;The base level of IP-10 had positive correlation with the change of HBV-DNA contents in therapeutic 12th week( P ＜0.05 ) ;The change of ALT level in reponse patients in therapeutic 12th week had positive correlation with the change of IP-10 、RANTES levels( P ＜ 0.05 ).Conclusion The decrease of IP-10,RANTES level in CHB patients received 12weeks interferon-α therapy could lead to reduce liver inflammation;The base IP-10 level probably was relevant to the early response in CHB patients received interferon-α therapy.

Nosocomial infections: an investigation of 27 129 inpatients / 中国基层医药

ObjectiveTo explore the effective measures to prevent and control the hospital infections.MethodsThe hospital infections'data of 27 129 inpatients were retrospectively studied and retrospectively analyzed.ResultsThe nosocomial infection rate was 3.40％. The major sites of the infection were lower respiratory tract (50.05％ ). The most common pathogens were mainly Gram-negative bacteria (41.91％ ). The infection mainly occurs in old peple(75.34％ ). The highest infection rate is in organ transplantation unit( 14.62％ ). The factors of high risk included antibiotics(53.47％ ), immunocompromise and invasive therapies. ConclusionTo improve the pathogen detective rate and the monitoring of antibiotic resistance ,to decrease the use of invasive therapies and to keep high risk areas under surveillance were the effective measures to control hospital infection and to reduce the incidence rate of hospital infection.

Liver histological changes after adefovir treating in chronic hepatitis B patients with HBeAg negative / 中国基层医药

Objective To investigate hepatic pathohistological changes(including pathology,HBV markers in liver tissue)in patients with KBeAg negative chronic hepatitis B after adefovir therapy for 1 year.Methods 35 patients with HBeAg negative chronic hepatitis B were administered with 10mg adefovir once a day for one year.The needle biopsy of liver were performed before and after treatment.The routine HE stained liver tissue sections were evaluated and Knodell pathological score were done.HBsAg and HBeAg in liver tissue were examined by immunohisochemisty method.Results After 1 year,18,17 and 11 cases had a significant reduction of their total hepatic HAI score,necroinflammation and fibrosis score.The immunohistochemistry examination showed HBeAg in liver decreased significantly,but HBsAg had no obvious alteration.Conclusion Significant improvement in both necroin flammation and fibrosis can be obtained in the majority of patients treated with adefovir for 1 year.More significant improvement in live histology can be obtained after extended treatment.

The impression of 4-combine radical treatment to the concentration of blood ammonia in patients with liver cirrhosis and helicobacter pylori infection / 中国基层医药

0.05).Conclusion The 4-combine radical treatment to Hp infection can reduce the concentration of ammonia in gastric juice and blood ammonia obviously in patients with liver cirrhosis,whose Child-Pugh grade are A and B,and the treatment is effective in preventing heptic encephalopathy.
