Objective To reproduce an experimental model of microsurgical reversible obstruction jaundice by micro-surgical technique. Methods Eight Banna miniature pigs were equally and randomly assigned into model group and control group. An improved Foley catheter was put into gall bladder of the pigs in the control group. A biliary calculus removal balloon tube was inserted into the common bile duct through the cystic duct in the experimental group to establish either partial or total biliary obstruction. The obstruction could be relieved by withdrawing the balloon tube from the common bile duct. Biliary tract visualization was conducted to evaluate the biliary obstruction, and venous blood samples were collected to determine the liver function (such as serum levels of TBIL and ALT etc.) in all pigs on the 2nd, 4th and 6th day after operation. Results Cholangiography showed a progressive dilation of both common hepatic duct and intrahepatic bile duct in the experimental group when the partial biliary obstruction was induced. During the periods when the total biliary obstruction was created the common bile duct, the common hepatic duct and intrahepatic bile duct of the animals in the experimental group were dilated progressively too. Both intra- and extra- hepatic bile ducts changed significantly compared to the control group. The dilatation subsided following the relief of obstruction. There was no dilatation of the bile duct in the control group. The serum levels of TBIL and ALT were significantly higher in the experimental group than that in the control group, and they were lowered after the relief of obstruction. Conclusion A microsurgical reversible obstruction jaundice model has been successfully reproduced with a biliary calculus removal balloon tube. It may provide a reliable experimental method for researches on the pothogenesis and treatment of obstruction jaundice.

Background Leber hereditary optic neuropathy (LHON) is a disease characterized by maternal inheritance.A number of mitochondrial DNA (mtDNA) mutation has been thought to be associated with this disease.Objective This study was to investigate the clinical and molecular genetic properties of LHON in two Chinese families.Methods Forty subjects from two Chinese families with LHON were enrolled in Affiliated First Hospital of Zhengzhou University,including 28 maternal members (10 of these members are LHON and 12 controls from two families.All the participants had a complete ophthalmic examination including visual acuity,direct ophthalmoscopy,color sensation and visual evoked potentials.MtDNA was extract from the whole blood sample of all participants.PCR-DNA sequencing was performed to detect the point mutation of the G11778A,T14484C,and G3462A for each subject.Written informed consent was obtained from each subject prior to this study.Results Only G11778A point mutation was identified in all 28 maternal members from the two families.No point mutation of G11778A was identified in non-maternal members,and no point mutation of the T14484C and G3462A were found in the two families.Conclusions The inherited pattern of these two families shows typical clinical and genetic features of LHON.LHON patients with G1 1778A mutation have a poor prognosis of visual acuity.

Objective To provide clinical evidence for the optimal acupuncture time in acupuncture treatment of hearing disorder in kids with cerebral palsy.Method Ninety eligible patients were randomized into 3 groups, 30 in each group. Group A was treated for 30 min, group B for 45 min, and group C for 1 h. The hearing improvement was evaluated by using brain-stem auditory evoked potential (BAEP).Result The detection of BAEP showed that the latent and peak periods of wave I,Ⅲ, and V were significantly shortened in the 3 groups after intervention (P<0.01), suggesting that acupuncture can produce a marked efficacy in treating hearing disorder in cerebral palsy. The inter-group comparisons showed that the efficacy of group A was significantly higher than that of group B and C (P<0.05); there was no significant difference in comparing the efficacy between group B and C (P>0.05). It’s indicated that the optimal acupuncture time span should be 30 min.Conclusion With the same acupuncture skills, acupuncture for 30 min can produce a comparatively higher efficacy in treating infantile hearing disorder.

Objective To investigate the assoiation between rheumatoid arthritis(RA)and the pres- ence of the shared epitope(SE)of HLA-DRBI gene in Han nationality of Neimenggu population.Methods The method of DNA amplification with sequence-specific primers(PCR-SSP)was used to determine 17 alleles of HLA-DRB1*01,*04,*10 genotypes in 80 RA patients and 110 healthy controls from the Han nationality population in Neimenggu.Results The frequencies of SE were significantly increased in RA patiens com- pared with controls(48.8%:20%,P＜0.01).Epitope analysis revealed that the most predominant allele subtype of DR4(*0405)was usceptible sequence in Neimenggu patients with RA(28.8%:12%,P＜0.01).No statisticall significant difference of other subtypes of DR1,DR4 nd DR10 was noted including DRB1*0101(2.5%:0.9%), *0102(2.5%:0),*0103(1.25%:0.9%),*0104(2.5%:0),*0401(6.25:1.8%),*0402(3.75%:0.9%),*0403 (1.25%:1.8%),*0404(2.5%:1.8%),*0406(2.5%:2.7%),*0407(1.25%:0.9%),*0408(3.75 %:0.9%),*0409 (1.25%:0),*0410(2.5%:0.9%),*0411(0:0)and *1001(8.75%:4.5%)respectively.Logistic regression analy- sis showed that the disease of patients with SE homozgote was more severe than that of patients with heterozy- gote(P＜0.01).Conclusion The results suggest that there is an association between SE of HLA-DRBI gene and susceptibility and severity of RA,especially,HLA-DR4 subtypes are strongly associated with RA in Han nationality in Neimenggu population.

OBJECTIVETo discuss the TCM pattern classification and measurable diagnosis criterion of the protracted symptoms of heroin-addiction abstinence (PSHAA).

METHODSThrough literature review and clinical study, the concept of TCM patterns and diagnostic standard were established, and a TCM pattern scale for quantitatively analysis of PSHAA was formulated. The scale were used on the clinical investigation on the abuser for 5 times on day 15, 30, 60, 90 and 120 after abstinence. Then the TCM patterns of PSHAA was classified using methods of DME and quantitative diagnosis, to create a corresponding scale of diagnostic indexes referring maximum likelihood method.

RESULTS(1) The TCM patterns of PSHAA commonly seen were Toxin-stasis accumulation (TSA) with Qi-blood insufficiency, TSA with Qi-yin deficiency, TSA with Yin-deficiency and Fire-excess and TSA with Yin-Yang deficiency. (2) The retrospective and prospective verification of the scale of diagnostic indexes showed it has high sensitivity and speciality, with low rates of misdiagnosis and of missed diagnosis.

CONCLUSIONIt is feasible to develop measurable diagnosis on the TCM patterns of PASAA using DME method and measurable diagnostic methods. The scale of diagnostic indexes formulated with the maximum likelihood method of quantified diagnosis has a certain clinical practicability.
