Hepatitis B associated with glomerulonephritis (HB-GN) has been increasing year after yea-r Tehispaper reports 24 cases of HE-GN treated between 1979 and 1984 whose clinical manifesta tion(?)the laboratory data confirmed the diagnosis. Our observations show that HB is mor often associated with extrahepatic lesions, sometimes appearing as the initial disorder or syndrome, including glomerulonephritis, carditis, arthritins, gastrocntentis and/or serum sickness, etc. HB-GN is also a kind of immune complex GN, whose pathogenesis is usually associatede with chronic active hepatitis, especially a decrease in the immune function of the Patient. Complex treatment, including liver Protection and immune stimulant treatment (blood and/or Plasma transfusion, thymosin, or levamisole)could give a better therapeutic effect.

This study was aimed to further explore theory of small intestinal diseases and its principle of syndrome differentiation and treatment and lay the base for the clinical study, through the clinical research on the treatment of small intestinal diseases. Through the clinical survey among 584 patients, using Traditional Chinese Medicine (TCM) Clinical Multidimensional Relational Query System, which was established by the research on the clinical individual diagnosis and treatment evaluation system on the prevention and treatment of diseases, to conduct the multidimen-sional relational analysis on small intestinal diseases' disease-symptoms-syndromes-therapy-medicines-effects. Using data mining and statistical methods, such as WEKA, Business Objects, SPSS to mine and analyze the syn-dromes and symptoms. The results showed that commonly-used TCM methods on treatment of small intestinal dis-eases, therapeutic principles of main syndromes of small intestinal diseases were summarized. It was concluded that through scale-free network diagram analysis on the commonly-used treatment of small intestinal diseases, the main treatment methods included promotion the flow of qi, relieving pain, tonifying spleen, removing dampness, clearing away heat, mildly regulating cold and heat. And the treatment methods of dispersing cold, invigorating blood circula-tion and removing blood stasis, nourishing yin, moistening and loosening bowels, abductively dispersing food stagna-tion were also used. It corresponds with the results of clinical research.

Objective To evaluate the safety and effect of adefovir dipivoxil (ADV) on hepatitis B in HBeAgpositive patients.Methods 131 patients were divided into two groups randomly.Two groups were treated with ADV (10mg/d)and matrine (0.6g/d),respectively.The rate of HBV negative,the normalization rates of ALT,HBeAg loss and anfi-HBe seroconversion were evaluated respectively.Results After 12 weeks of treatment,the rate of HBV negative,the normalization rates of ALT,HBeAg loss and anti-HBe seroconversion of ADV were all significantly higher than those of matrine group(53.2％ vs 7.8％,36.0％ vs 8.7％,13.6％ vs 3.1％,6.2％ vs 0,respectively,x2 =56.32,23.18,all P ＜ 0.01).Conclusion The domestic ADV superior to matrine in HBeAg-positive patients.

Objective To study the differences of electrolytes,C-reactive protein in different type,gender and recur- rent of febrile convulsion.Methods 174 cases of children febrile convulsion were collected.We detected the electro- lytes,C-reactive protein respectively and analyzed their relationship.Results In children febrile convulsion,the lev- els of the electrolytes,C-reactive protein had nothing to do with the type,gender and recurrent of the febrile convul- sion.Conclusion We should treat routinely the children who suffered from febrile convulsion without considering the type,gender and recurrent.

Objective To study the relationship between HCV chronic infection and expression of CXC chemokines mRNA.Methods The levels of IL-8,IP-10 and Mig mRNA in peripheral blood mononuclear cells(PBMC) of chronic hepatitis C patients were detected by real-time quantitative polymerase chain reaction(RT-PCR) before,and 3,6 months after combined therapy of interferon-?(IFN-?) and Ribavirin.The rate of chemokine/GAPDH was regarded as the extreme level of chemokine.Results The mean level of HCV-RNA and expressive levels of IL-8,IP-10,Mig mRNA in peripheral blood of HCV chronic infection were 2.09?10~(6)copies/ml,and(1.243 7?0.071 2),(0.682 8?0.073 8),(0.668 3?0.075 4),with significant difference with those of normal controls(P0.05).Conclusion The expressions of IL-8,IP-10 and Mig mRNA in PBMC are high in patients with chronic hepatitis C,and associated with the replication level of HCV,and less associated with the gene type of HCV.IFN-? can effectively restrain the replication of HCV and down-regulate the levels of IL-8,IP-10 and Mig mRNA near to normal level in patients with chronic hepatitis C.IFN-? plays an important role in down-regulating inflammation response and controlling the development of the patients' condition.
