Three hundred cases of E type viral hepatitis were observed with 100 cases of A type as control. We held that the etiology and pathogenesisof E and A types of viral hepatitis were wind, dampness, heat, poisons and stasis, each with its predominance; For A type, its predominant etiology being wind, heat and stasis, while that of E type, dampness, poisons and stasis. For their therapy, the principle of "similar treatment for different diseases " should, adopted. After treatment, ACT, TB, and a markedly decreased, signs and symptoms markedly improved, Epr, IgG also improved to different extents, the cured rate ( rate of negative virus exam) being 80% and 78% for A type and E type respectively. The effect was especially good for simple infection, and rather poor for mixed infection type.

As the patient of hepatitis B and E overlapping infection of liver and gallbladder damp - heat type compared with the patient of simple hepatitis E of liver and gallbladder damp-heat type, attack was very rapid, jaundice exacerbated progressively and hepatic function damaged severely. Aftertreatment the state of illness restored more slowly and the duration of illness was obviously prolonged. At the same time, it was found that the biochemical indexes (hyaluronic acid, total bile acid) increased significantly at acute stage, and the indexes in the patient of overlapping infection in the time for recovering normality at restoration stage was longer than that in the patient of simple hepatitis E, with a significantly difference between the two groups. It is indicated that lesion of the liver in the patient of overlapping infection of hepatitis B and E was more severe than the simple hepatitis E, with no good prognosis.

To study the effects of Qinggan Huoxue Recipe (QGHXR), the compound traditional Chinese herbal medicine, and its separated recipes on the expression of tumor necrosis factor-alpha (TNF-alpha) mRNA and serum TNF-alpha content in rats with alcoholic liver injury (ALI).

To study the distribution pattern of traditional Chinese medicine (TCM) syndromes in fatty liver disease.

OBJECTIVE: To investigate the effects of Qinggan Huoxue Recipe (QGHXR), a compound Chinese herbal medicine, and its decomposed formulas Qinggan Recipe (QGR) and Huoxue Recipe (HXR) on expressions of CD14, Toll like receptor 4 (TLR(4)) and nuclear factor-kappaB (NF-kappaB) in Kupffer cells. METHODS: The isolated primary rat Kupffer cells were treated with lipopolysaccharide (LPS) for a certain period of time, a series of concentrations of drug-containing serums of QGHXR and its decomposed formulas were added, the expressions of NF-kappaB, tumor necrosis factor-alpha (TNF-alpha), CD14, and TLR(4) of the Kupffer cells were detected in different culture conditions by using Western blot, real-time reverse transcription polymerase chain reaction (RT-PCR) and ELISA methods respectively. RESULTS: QGR could down-regulate the expression of membrane receptor CD14, but the expression of NF-kappaB and TNF-alpha were not significantly decreased after QGR treatment. HXR could down-regulate the expression of membrane receptor TLR4 and inhibit the expressions of NF-kappaB and TNF-alpha. QGHXR could down regulate the expressions of membrane receptors CD14 and TLR(4) and inhibit the expressions of NF-kappaB and TNF-alpha. CONCLUSION: QGHXR can protect liver cells by down regulating the expressions of CD14, TLR(4) and NF-kappaB and inhibiting TNF-alpha expression.

To study the action mechanisms of Qinggan Huoxue Recipe (QGHXR), a compound traditional Chinese herbal medicine, and its separated recipes by observing their effects on expressions of urokinase-type plasminogen activator (uPA) and plasminogen activator inhibitor-1 (PAI-1) in rats with alcoholic liver fibrosis (ALF).

Objective: To study the phenotypes and functions of dendritic cells (DCs) derived from peripheral blood monocytes of chronic hepatitis B (CHB) patients with different traditional Chinese medicine (TCM) syndrome types, and to explore the relationship between TCM syndrome type and DC functions. Methods: Sixty CHB patients were included in this study. All the CHB patients were divided into spleen deficiency and liver stagnation, spleen deficiency and dampness-heat and deficiency of both spleen and kidney groups according to TCM syndrome diagnosis standard. There were 20 cases in each group, and ten healthy people were included as normal control. The volunteer's peripheral blood was collected for monocyte separation, biochemical test and hepatitis B virus DNA loads detection. DCs were induced and isolated from peripheral blood monocytes, and then the expressions of surface markers CD80, CD86, CD1a and HLA-DR were detected by flow cytometric analysis method. Interleukin-10 (IL-10) production of the DCs was quantified by enzyme-linked immunosorbent assay. Results: The proliferation of DCs in the CHB patients was slower than that in the healthy volunteers (P<0.05). The expressions of DC surface molecules such as CD80, CD86, and CD1a were obviously decreased in the CHB patients as compared with those in the healthy volunteers (P<0.05). More over, expressions of DC surface molecules were different among CHB patients with different TCM syndrome types. The positive expressions of CD80, CD1a, and HLA-DR in the CHB patients with spleen deficiency and liver stagnation were obviously higher than those in the CHB patients with deficiency of both spleen and kidney (P<0.05), and the CD1a expression in the CHB patients with spleen deficiency and dampness-heat was higher than that in the CHB patients with deficiency of both spleen and kidney (P<0.05). In DC culture supernatant, the IL-10 concentration of the CHB patients with deficiency of both spleen and kidney was higher than that of the CHB patients with spleen deficiency and liver stagnation (P<0.05), and the IL-10 concentrations of the CHB patients with different TCM syndrome types were higher than that of the healthy volunteers (P<0.05). Conclusion: During the pathogenic course of CHB, the phenotypes and functions of DCs are different in CHB patients with different TCM syndrome types. It suggests that there is a correlation between TCM syndrome type and body immunity function.

Objective To study the effects of chronic manganism on hearing and cochlear cells in rats by using animal model of chronic manganism .Methods Sixty adult SD rats were randomly divided into Mn - exposed and controlgroups.RatsweretreatedwithMnCl24H2O(100mg·kg -1·d-1)ordeionizedwaterbygastricperfusion, lasted for 12 weeks .The Mn concentration in peripheral blood was measured respectively at 4 weeks ,8 weeks and 12 weeks after treatment .At 12 weeks after treatment ,the auditory brainstem response was recorded ,the hair cells morphology and counting were examined by stretched preparation of basilar membrane stained with FITC -phalloi-din ,and the spiral ganglion cells morphology and counting were studied by HE staining ,the ultrastructure changes of hair cells and spiral ganglion cells were detected by transmission electron microscopy .Results The blood Mn concentration increased gradually with time after treatment .ABR thresholds at 4 ,8 ,16 ,24 and 32 kHz were sig-nificantly increased at 12 weeks after treatment ,especially in the high-frequency range .Morphological study at 12 weeks after treatment showed loss of outer hair cells ,mainly in the basal turn of the cochlea ,and decreased number of spiral ganglion cells .The ultrastructure changes of outer hair cells and spiral ganglion cells included the break -ups ,disappearance or vacuolar change of mitochondria cristas .Conclusion Our data demonstrate that chronic man-ganism can cause loss of outer hair cells and spiral ganglion cells in cochlear in rats ,leading to hearing loss .

OBJECTIVE: To evaluate the efficacy and safety of Danning Tablet (DNT) in patients with non-alcoholic fatty liver disease (NAFLD) of damp-heat syndrome type. METHODS: A multicenter, randomized, double-blinded and positive drug parallel controlled trial was performed. One hundred and thirty-five patients were enrolled into the study and divided into two groups: DNT-treated group (n=102) and ursodeoxycholic acid (UDCA)-treated group (n=33). Body mass index (BMI), principal symptoms, liver function, blood lipids, iconographic, and compositional parameters were measured before and after treatment, respectively. RESULTS: In the two groups, BMI, distress in hepatic region, fatigue, anorexia, liver function, blood lipids and iconographic parameters were significantly improved, and the improvements of BMI, distress in hepatic region were better in DNT-treated group than in UDCA-treated group. The histological study also showed that DNT had positive effect in treatment of NAFLD. CONCLUSION: DNT is an effective drug to treat patients with NAFLD of damp-heat syndrome type and is more effective than UDCA.
