Marfan's syndrome(MFS) is a relatively common autosomal dominant hereditary disorder with prominent manifestations in the skeletal, ocular, and cardiovascular systems. MFS has a high penetrance. Recent research on the pathogenesis and diagnosis and therapy of MFS has made a lot of progress. So we reviewed the advance on the relation of molecular genetics and phenotype of MFS.We discussed the molecular hasis, gene mutation and location, diagnosis, clinical features and therapy. Now the detection on the molecular level has been a very important method in diagnose MFS very early or before bom.

BACKGROUND: AdiponecUn (apM1) has been a new target for gene therapy of ischemic diseases; apM1 gene cloning is the key of successful apM1 gene therapy. There are two main gene cloning methods: directional cloning and T-A cloning method. Directional cloning method is complicated, while the T-A cloning method is relatively simpler, with higher successful rate. OBJECTIVE: T-A cloning of apM1 gene coding region was applied to verify the sequence in comparison with GenBank. DESIGN, TIME AND SETTING: The gene verification experiment was performed at the laboratories of Fujian Hypertension Research Institute which is in The First Affiliated Hospital of Fujian Medical University and Academy of Integrative Medicine which is in Fujian University of Traditional Chinese Medicine, from June 2006 to December 2008. MATERIALS: Adipose tissue sample of omental fat pad was obtained from a surgical patient in the First Affiliated Hospital of Fujian Medical University. Trizol produced by Invitrogen company; M-,-MLV, Gel Extract Kit produced by PROMEGA company; Taq enzyme produced by TIANGEN company; Restriction Endonucleases BamH Ⅰ and Sal Ⅰ, pMD18-T Vector produced by TAKARAcompany were used in this study.METHODS: Total mRNA was extracted from human greater omentum adipose tissue. The coding region of human apM1 (hapM1) gene was amplified by RT-PCR. The coding region of hapM1 gene was cloned into pMD18-T vector .The recombinant plasmid was identified with restriction enzyme digestion analysis and nucleotide sequencing. MAIN OUTCOME MEASURES: The electrophorasis verification of the recombinant plasmids coding target gene using double enzyme digestion, comparison of the similarity between the sequences of the plasmids and hapM1 in GenBank. RESULTS: Sense and antisense coding region of hapM1 gene were cloned. The sequencing results showed that the sequences of the cloned DNA were completely identical to that of hapM1 in GenBank.CONCLUSION: The coding region of hapM1 gene was successfully cloned.

Aim To investigate the expression of the lentiviral vector carrying a human apM1(hapM1) gene in 293 T cells and its bioactivity.Methods The CDS region of hapM1 gene was subcloned into the lentiviral vector from a cloning vector,and the transfer plasmid(PNL-hapM1-IRES2-EGFP)of the lentiviral vector was constructed.The three plasmids of the lentiviral vector: PNL-hapM1-IRES2-EGFP,HELPER,and VSVG were cotransfected to 293 T cells to produce the recombinant lentivirus;293 T cells were infected by the recombinant lentivirus and were identified with fluorescent microscope,RT-PCR and western blot.Inhibitory effect of the recombinant hapM1 on proliferation of vascular smooth muscle cells(VSMCs) was identified.Results The sequencing results showed that the sequence of the subcloned hapM1 gene was completely identical to that reported in GeneBank.The virus titre of the recombinant hapM1 lentivirus was 2.0?105 TU?L-1.After the recombinant lentivirus infected 293 T cells,RT-PCR and Western blot results showed that the expression of hapM1 in the hapM1-293 T group could be measured.The recombinant hapM1 inhibited the proliferation of VSMCs.Conclusions The recombinant lentivirus carrying a human apM1 gene was constructed successfully.The recombinant hapM1 could be expressed in 293 T cells and had its bioactivity.

Objective:To evaluate the effect and safety of penehyrclidine hydrochloride when it was applied preoperatively in outpatient.Method:240 patients were randomly divided into two groups.Group P(120 cases)was treated with penehyclidine hydrochloride 0.5mg before the anesthesia as Group A(120 cases)with Atropine 0.25 mg.Sedation scale was observed just 5 and 15 minutes after drug administration.Analge scale,the degree of the patient's dry-mouth and PONV were also recorded.Time of recovery and leaving were studied too.Result:Group P had significantly better analgesic efficacy than Group A(P0.05).The degree of the patients dry-mouth were statistical difference between 2 group both 15min and 4h postoperation(P

[Objective] To observe the effect of serum containing Bushen prescription (BP) on inhibition of chondrocyte proliferation and nitric oxide (NO) production in chondrocyte induced by interleukin-1 (IL-1). [Methods] Four New Zealand rabbits were administered BP 2.5mL (1.15kg/L) for 3 days for the preparation of BP-containing serum. Rabbit chondrocytes were cultured in-vitro and were added with DMEM culture containing IL-1 1, 10 and 20 ?g/L to examined the inhibition concentration of IL-1 for chondrocyte proliferation. After then, BP group was added with 20 ?g/L IL-1 and various concentrations of BP-containing serum and the model group with 20 ?g/L IL-1 and various concentrations of blank serum. Alter 3-day culture, chondrocyte proliferation were dectected by thiazolyl blue colorimetry (MTT) and NO content by Griess method. [Results] The inhibition concentration of IL-1 for chondrocyte proliferation was 20 ?g/L; various concentrations of BP-containing serum could counteract chondrocyte proliferation and inhibit NO pnxluction in chondrocyte induced by IL-1. [Conclusion] BP can counteract chondrocyte proliferation directly or indirectly by the mediation of NO, which may be one of its therapeutic mechanisms in treating osteoarthritis.
