Objective To explore the association of Gly71Arg mutation in gene of bilirubin uridine 5'-diphosphate-glucuronosyltransferase(UGT1A1)and neonatal jaundice in Beijing city Han population.Methods The genotypes and alleles of the Gly71 Arg polymorphism for UGT1A1 gene were identified by polymerase chain reaction-restricted fragment length polymorphism assay in infants of Beijing city Han population of China,including 96 infants with neonatal jaundice[serum bilirubin(307.06?38.5)?mol/L,indirect bilirubin(292.9?35.9)?mol/L] and 101 healthy control infants [serum bilirubin(131.2?42.1)?mol/L,indirect bilirubin(126.3?39.7)?mol/L].The genotypes and allele frequencies of the polymorphism were compared between infants with neonatal jaundice group and healthy infant group(control group).The effect of polymorphism in infants with neonatal jaundice group on serum bilirubin level were analyzed.Results There were significant differences in genotypes distribution in Gly71Arg polymorphism for UGT1A1 gene between the 2 groups(?2=9.47 P=0.002).Compared with control group,neonatal jaundice group had significantly higher Arg allele frequency in the polymorphism for UGT1A1 gene(?2=10.34 P=0.001).There were independent effects of Gly71Arg mutation in the gene on serum bilirubin level in neonatal jaundice group,at the carriers of homozygote of the Arg allele of Gly71Arg polymorphism had higher serum bilirubin levels compared to carriers of heterozygote of the Arg allele of the polymorphism and non-carriers of the Arg allele of the polymorphism(Pa

With the development of the health service in china,the old talent-training program for clinical medicine major was failed in meeting higher demands for talents of clinical medicine. To create the new talent-training program,therefore,has become the main content of teaching reform for medical col-leges and universities. Taking University of South China as an example,the paper analyzed the changing trend of talent-training program for five-year clinical medicine majors from talent-training goal,curriculum system,practical teaching and content of courses,which proposed some thoughts on the optimization of training program for clinical medicine majors.

To investigate the cell-killing effect and its possible mechanism of rClone30-hDR5 in combination with TRAIL on human hepatic carcinoma (HCC) cell line, first of all, recombinant plasmid pee12.4-hDR5 was introduced into HepG2 cells by liposome transfection. After five rounds of screening by flow cytometry, HepG2 cells expressing high levels of DR5 on cell surface were isolated. The cytotoxicity of TRAIL to selected cells was higher than that of TRAIL to HepG2 cells by MTT method (P < 0.01). The result suggested that the cloned hDR5 gene had biological activity. MTT assay showed that, rClone30- hDR5 in combination with TRAIL more efficiently inhibited the tumor growth of HepG2 cells compared to rClone30-hDR5 or TRAIL in vitro. The results of Annexin V-FITC/PI staining and Quantitative Real-time PCR indicated that rClone30-hDR5 in combination with TRAIL significantly increased the mRNA levels of caspase 3 and caspase 8, and induced the apoptosis of tumor cells. HepG2 cells were infected with rClone30-hDR5 or rClone30 at MOI of 1. The expression of hDR5 on tumor surface increased significantly by rClone30-hDR5 compared to that by rClone30, which contributed to the sensitivity to TRAIL. In conclusion, rClone30-hDR5 in combination with TRAIL has potential application value in cancer treatment.

This study was purposed to investigate the effect of bortezomib (Bor) and arsenic trioxide (As(2)O(3)) combination on multiple myeloma cell line KM3 and its mechanisms. KM3 cells were cultured with different concentration of Bor or As(2)O(3) as well as both for a certain time. The cell proliferation was analysed by MTT assay and the concentration of 50% proliferation inhibition (IC(50)) was calculated. Early apoptosis and late apoptosis of KM3 cells were detected by Annexin-V-FITC Kit, and the change of transmembrane potential was measured by flow cytometry. mRNA of Caspase-3, Bim and Bcl-xL were detected by RT-PCR. The results showed that the proliferation inhibitory rate of KM3 cells treated by Bor plus As(2)O(3) was much higher than that of KM3 cells treated by Bor only for 72 h [ (27.64 ± 0.81)% vs (21.67 ± 2.20)%, P < 0.05]. There were more KM3 cells treated by Bor plus As(2)O(3) in early apoptosis at 48 h and late apoptosis at 72 h than that of KM3 cells treated only by Bor [ (53.20 ± 3.70)% vs (35.40 ± 2.58)%, P < 0.01; (63.96 ± 2.97)% vs (54.08 ± 3.76)%, P < 0.01]. Transmembrane potential (Δψm) of KM3 cells treated by Bor plus As(2)O(3) decreased more at 48 h, as compared with Bor alone. The expression levels of caspase-3 mRNA and Bim mRNA in KM3 cells treated with Bor plus As(2)O(3) were higher than that in KM3 cells treated with Bor alone. But the expression level of Bcl-xL mRNA was lower than that in KM3 cells treated with Bor alone. It is concluded that As(2)O(3) can enhance the apoptosis-inducing effect of Bor on multiple myeloma cell line KM3, which is associated with decreasing the expression of Bcl-xl mRNA and increasing the expression of Caspase-3 and Bim mRNA.

Meloxicam concentration in skin was determined following topical administration of meloxicam patches in hairless mouse. Samples were analysized by HPLC coupled with microdialysis sampling technique, in which in vivo recovery of probe was characterized by the retrodialysis method. It was indicated that the in vivo recovery of the probe was 14.0%. The range of steady state concentration of meloxicam in dialysate was 24-50 ng x mL(-1), and that was 170-360 ng x mL(-1) in the hairless mouse skin. Steady state concentration of meloxicam was reached shortly after the application of meloxicam patches, which was maintained during the period of experiment.

OBJECTIVETo explore the indication of hysterectomy after successful resuscitation of cardiac arrest due to obstetric hemorrhagic shock.
METHODSA retrospective analysis was conducted in 13 patients with cardiac arrest due to obstetric hemorrhagic shock in 7 hospitals of Guangzhou, including 12 patients undergoing hysterectomy and 1 undergoing uterine artery embolization.
RESULTSs After successful cardiopulmonary resuscitation, only 4 of the 13 patients undergoing hysterectomy or uterine artery embolization for continuing uterus hemorrhage survived.
CONCLUSIONDetailed plans and emergency measures should be formulated in the management of high-risk pregnancies. Early diagnosis and active treatment of obstetric hemorrhagic shock with hysterectomy or uterine artery embolization are critical in preventing cardiac arrest and improving the survival of the patients.

OBJECTIVETo obtain the monoclonal antibody against hexon protein of human adenovirus.
METHODSBALB/c mice were immunized with purified recombinant hexon protein, and the spleen cells of the mice were isolated and fused with myloma cells. Four hybridoma cell strains were screened by indirect ELISA and cultured, and the sensitivity, specificity and virus neutralizing activity were analyzed with ELISA, Western blotting and neutralizing test.
RESULTSThe mouse ascites produced by these hybridoma cells contained specific monoclonal antibodies against hexon protein of human adenovirus as identified by ELISA and Western blot, and the antibody generated by 4C6 strain showed human adenovirus type 3-neutralizing activity.
CONCLUSIONThe monoclonal antibodies against hexon protein with high specificity have been successfully obtained, and these antibodies can be useful in developing assays for early diagnosis of HAdV3 infection and also in study of therapeutic drugs of the infection.
