Chinese Pharmaceutical Journal 2012;47(24):2017-2022
OBJECTIVE: To study the genotype distribution of cytochrome CYP3A4, CYP2C9, CYP2C19, CYP2D6 in Han and Mongolian Chinese population and the allele and genotype frequency are compared between the Han and Mongolian. METHODS: CYP3A4, CYP2C9, CYP2C19, CYP2D6 of Han and Mongolian Chinese population were genotyped by PCR-RFLP. RESULTS: The allele frequencies of CYP3A4 * 5 in Han and Mongolian are 0, the allele frequencies of CYP3A4 * 18 in Han and Mongolian are 0.1838, 0.2025. The allele frequencies of CYP2C9 * 2 in Han and Mongolian are 0.0110, 0.0253; the allele frequencies of CYP2C9 * 13 in Han and Mongolian are 0, 0.003 2.The allele frequencies of CYP2C19 * 2 in Han and Mongolian are 0.386 0, 0.4146, the allele frequencies of CYP2C19 * 3 are 0.0515, 0.0443. The allele frequencies of CYP2D6 * 10 in Han and Mongolian are 0.5735, 0.4652. CONCLUSION: The study shows that there are no significant ethnic differences in the distribution of CYP3A4 * 18, CYP2C19 * 2, CYP2C19 * 3, CYP2D6 * 10 genotypes in Han and Mongolian. The CYP3A4 * 5 genotype is not found in this study and only one CYP2C9 * 1/* 13 genotype is found in Mongolian. For CYP2C9 * 2, the Mongolian is significantly lower than the Han, (P=0.023).

OBJECTIVETo evaluate clinical outcomes of anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) reconstruction under arthroscopy and repair of the injured posteromedial complex structure of the knee joint in the treatment of posterolateral knee dislocation with multiple ligament injuries.
METHODSFrom March 2008 to August 2012,22 patients (16 males and 6 females, ranging in age from 20 to 53 years old, with an average of 30.5 years old) with posterolateral dislocation of the knee were treated with primary reconstruction of ACL and PCL, combined with the repair of injuries in the posteromedial complex and soft-tissue. Eight patients had injuries caused by sports,5 patients road accidents and 9 patients falling down. The ACL was reconstructed using the gracilis and semitendinosus tendons. The PCL was reconstructed using LARS artificial ligaments (14 cases), or gracilis and semitendinosus tendons (8 cases). Suture repair was performed in 17 patients with posteromedial ligament injuries,and self-semitendinosus strengthening operations were performed in 5 patients. Continuouspassive montion (CPM) and active exercises were executed after operation at early stage. The IKDC and Lysholm system were used to evaluate therapeutic effects.
RESULTSAll the patients were regularly followed up, and the duration ranged from 11 to 56 months (averaged, 39 months). According to the IKDC scale,9 patients got a grade A result, 10 got a grade B result, and 3 got a grade C result. The IKDC subject score was 89.6±3.1 and the Lysholm scores was 90.7±1.8 at the latest follow-up, which were both better than those before operation.
CONCLUSIONReconstructing the ACL and PCL and repairing injured posteromedial complex of the knee followed by an active rehabilitation is an effective method to treat posterolateral knee dislocation.

Objective To investigate the protective effect of Gingko Biloba extract (GBE) on acute lung hemorrhage induced by Lipopolysaccharide(LPS) in newborn rats. Methods 1. Acute lung hemorrhage models were reproduced by intraperitoneal injection with LPS (5 mg/kg). 2. Thirty two rats were randomly divided into 4 groups,GBE groups (4 mg/kg,8 mg/kg, 16 mg/kg) and LPS group 5 mg/kg. Results In group LPS, extensive lung hemorrhage was observed after 4 hours of injection . TNF - ? iung content was obvious in LPS group. The expression of lung nuclear factor(NF-kB )immunohistochemistry wasobvious. While the parameters were obviously attenuated by GBE before LPS. Conclusion GBE may be useful in the treatment of acute pulmonary inflammatory disease.

Objective To establish mouse model of dementia by intracranial injection of A?25-35 and small amount of ibotenic acid(IBO) and to explore whether the effects of catalpol can affect the brain M receptor density and the short term memory. Methods The mice were randomly divided into three groups: control group,model group,treat group which were given orally for 2 months with 50 mg?kg-1?d-1 of catalpol.Dementia model was developed by single unilateral injection of 0.3 ?L of a solution of A?(1?L normal saline containing 4 ?g of A?25-35 and 1 ?g of ibotenic acid) into right basal ganglion region according the atlas of mouse brain with the aid of a stereotaxic equipment.The track of injection was observed by HE staining.The learning/memory ability was measured by Y-maze perfor-mance.The brain muscarinic receptor density was analyzed with single-site binding assay using 3H-quinuclidinyl benzilae(QNB).Results Two months after model development,the learning ability as well as the density of muscarinic receptor in brain were significantly decreased in model mice compared with those in control mice.Parallel models treated with daily oral administration of Catalpol for two months improved the learning ability and increased the brain muscarinic receptor density when compared with model mice.The correlation coefficient between total M receptor densities and the learning/memory ability was significant when examined with linear regresion.Conclusion A dementia model was established in mice.Dementia model was developed by single unilateral injection of 0.3 ?L of a solution of A?(1 ?L normal saline containing 4 ?g of A?25-35 and 1 ?g of ibotenic acid) into right basal ganglion region was established in mice.Catalpol can significantly improve the learning and increase the brain muscarinic receptor density of the model.

Objective To produce a hybridoma secreting stable monoclonal antibodies against Aβ22-35 and to develop a detection method for the assay of Aβ. Methods Spleen cells from Balb/cmice immunized with Aβ22-35-KLH were fused with mouse myeloma cells SP2/0. The techniques of immunoprecipitation and western blotting plus ECL were used to investigate the levels of Aβ in the rat brain. Results Two strains of hybridomas (3A8 and 3B2) secreting stable monoclonal antibodies raised against Aβ22-35 were obtained. The subtypes of Aβ22-35 were IgG3. The levels of Aβ in young and older rat brain were 9.8±2.8 and 13.36±2.65 (pmol/12mg brain tissues, x±s), respectively. Conclusion The Aβ22-35 mAb obtained had high titres and specificity. The levels of Aβ in the older rat brain were significantly increased as compared with the young one (P<0.05).

Objective To explore the adverse effects of formaldehyde(FA)on learning and memory ability of mice and the antagonistic effect of N-acetyl-cysteine(NAC),an antioxidant.Methods Thirty-four ICR mice were randomly divided into four groups,the control(NS,n=8),treated with FA(15 mg/kg,n=9),treated with NAC(100 mg/kg,n=8),treated with FA(15 mg/kg) plus NAC(100 mg/kg,n=9),the treatment was conducted by intraperitoneal injection once a day for seven consecutive days.On the eighth day,the learning and memory ability were tested by using water labyrinth task for seven consecutive days.Results The mice in FA group behaved excited,restless and then turned to repose,moveless and clustering,but this phenomena was not seen in the other groups.There was no significant difference in the body weight of mice among groups.As for learning,latent period in the FA group [(27.15?2.66)s] was significantly longer than that in the control group [(15.83?2.82)s] and the FA+ NAC group[(14.98?2.66)s],and revealed statistical significance(P
