Objective: To investigate rules and affect factors in virus hepatitis complicated with biliary system damage. Methods: To observe 158 patients with various clinical types of viral hepatitis, gallbladder filling degree of gallbladder wall thickness, the gallbladder bile in the gallbladder situation, through sound situation by ultrasound, and the patients with intrahepatic, extrahepatic bile duct wall thickness were measured, the clarity of cavity were observed. Results:The 158 cases of patients with biliary ultrasonic testing results showed the gallbladder wall thickening, rough bilateral syndrome, sound transparent difference, stones, gallbladder enlargement or smaller, like solid. Severe hepatitis, biliary system in patients and liver cirrhosis was significantly higher than that of the abnormal in patients with acute hepatitis and chronic hepatitis (x2=17.96, x2=16.27; P<0.05). Conclusion: Viral hepatitis complicated with biliary system damage is related to clinical type, course of disease, liver function damage. Observe the change of ultrasonic dynamic biliary system, liver function testing timely, and provide the basis for guiding clinical treatment, to judge the severity and chronicity of hepatitis prediction.

The paper studied effect of different doses of Tanshinone on human polymorphonuclear leucocyte chemokinesis by agarose microdroplet assay. The results indicate that more than 10ng/ml Tanshinone inhibites significantly human polymorphonuclear leucocyte chemokinetic response to 10~(-9)M FMLP. This inhibitory effect is probably one of mechanisms of Tanshinone anti-inflammatory activity. The agarose microdroplet assay is a reliable mothod for studying leucocyte chemokinesis in vitro.

Objective To investigate the association between human leukocyte antigen DRB1gene (HLA-DRB1) polymorphisms and asthma among Mongolian and Han peoples in China. Methods Sequence-specific primer polymerase chain reaction (PCR-SSP) was used to detect frequencies of HLA DRB1 alleles in 45 Han and 45 Mongolian patients of asthma, as well as 46 healthy Han and 45 healthy Mongolian people as controls. Frequencies of each locus of HLA-DRB1 gene were calculated and odds ratio (OR) for each locus was estimated and tested by chi-square test. Results Frequency of HLA-DR9 allele was significantly higher in Han ( 13.33 %, OR of 7. 82) and Mongolian ( 16.67 %, OR of 4. 10) asthmatic patients, as compared to Han ( 2. 22 % ) and Mongolian ( 5.43 % ) controls, respectively ( P < 0. 05 ) ;frequency of HLA-DR11 allele in Mongolian asthmatic patients ( 10. 00 % ) was significantly higher than that in healthy Mongolians ( 1.11% ) ( P < 0. 05, OR of 11.00 ) ;and frequency of HLA-DR7 allele in Han asthmatic patients was significantly lower than that in healthy Han people ( P < 0. 05, OR of 0. 08 ). Frequency of HLA-DR7 allele in Han asthmatic patients (1.11% ) was significantly lower than that in Mongolian patients (10. 87 % ). Conclusions HLA-DR9 allele is a common in the people of Inner Mongolian Autonomous Region, and associated with susceptibility of asthma in Han and Mongolian peoples. HLA-DR11 allele is a unique susceptive gene for Mongolian asthmatic patients and HLA-DR7 allele is a protecting one for asthma in Han people.

Pineal arteries and veins of 46 adult human brains were observed and measured with stero-microscope and light microscope.According to the number of branches, the pineal arteries may be classified into four types: single branched, double branched, three branched and multiple branched types. Among them the single and double branched type occur most frequently. (in 54.55% and 34.09％ respectively), the artery originates mainly from the postcromedial choroidal artery (in 69.72％), and the next more frequent origin is the the quadrigeminal artery (in 28.87%). Some pineal arteries have double origins from abovementioned arteries.Most of the starting points of pineal arteries situate in the recess between the superior colliculus and the pineal body, and less of them on the lateral side of the colliculus or beneath the splenium of the corpus callosum. The artery runs frequently forwards or medially towards the gland and enters it at the middle part of its side. Then it gives branches out of or in the capsule to the surface the gland. The branching patterns may be classified into four types and ten subtypes.The arteries vary in length from 0.2～38.4 mm. The mean external diameter of which is 0.30+0.08 mm, and the internal diameter,0.21?0.07mm.On the pineal body there are a pair of venous stems known as choroidal-pineal veins. They begin from the tela choroidea of the third ventricle. After accepting the dorsal and ventral pineal veins on the ventrolateral side of the pineal body, the two venous stems usually unite to form a single vein which converges into the great cerebral vein.
