The factor VIII gene is located on the X chromosome,making haemophilia A, a sex-linked disorder. Thus on pedigree grounds all daughters of such patients are obligate carriers. One female case of haemophilia A was reported and related literatures were reviewed.

The drug release characteristics ofDa Chuanxiong Fang multiunit drug delivery system (DCXFMDDS) in vivo and in vitro were evaluated. Ferulic acid (FA) and senkyunolide I (SI) were used as marker components, which were two of the effective components of Da Chuanxiong Fang. And their contents were determined by HPLC. Drug release characteristics in vitro of DCXFMDDS and Da Chuanxiong pills and pharmacokinetics characteristics of DCXFMDDS and Da Chuanxiong Fang active fraction (DCXFAF) in rats were compared. It was obvious that FA released from the DCXFMDDS in a sustained fashion but SI in a fast fashion both in vitro and in vivo. The releasing process and the releasing mechanism of FA and SI from DCXFMDDS were different, but the AUC value indicated that compared with DCXFAF the extent of absorption of FA and SI from DCXFMDDS was increased. Though from the same multiunit drug delivery system, FA an SI had different drug release characteristics both in vitro and in vivo, and that may be one of the reason why DCXFMDDS has the good properties such as rapid and long-lasting effect and high efficiency.

Oral sustained- and controlled-release drug delivery systems of traditional Chinese medicine (TCM) are a research hotspot in the development of drug-delivery systems for TCM. The quality evaluation system is an important guarantee for the safety and efficiency of these drug-delivery systems. In this paper the methods to construct such quality evaluation system were discussed.

[Objective]To explore the roles of TIDC(tumor infiltrating dendritic cell)and TIL-T(tumor infiltrating T lymphocyte)in tumor immunity of EBV-associated gastric carcinoma(EBVaGC)and their clinical significance.[Methods]TIDC and TIL-T in EBVaGC(n=49)and EBVnGC(EBV-negative gastric carcinoma)(n=20)were detected by immunohistochemistry method and then their subtypes and their relationships with clinical and pathological factors were analyzed.[Results]Mild infiltration was detected in 29 of 49(59.2%)EBVaGCs and 18 of 20(90%)EBVnGCs,while marked infiltration of TIDC was detected in 20 of 49(40.8%)EBVaGCs and 2 of 20(10%)EBVnGCs.And the difference between the two groups was significant (P=0.013).The number of TIL-T in EBVaGC was hisher than that in EBVnGC(P=0.017),and most of them were CTLs.The number of TIL-T was positively correlated with that of TIDC(r=0.386,n=49,P=0.006).The degree of TIL-T infiltration in EBVaGC had negative relationship with the lymph node metastasis(P＜0.001),while TIDC had no relationship with the clinical features.[Conclusion]TIDC and TIL-T may play important roles in the tumor immunity of EBVaGC;TIDC may contribute to the TIL-T recruitment in EBVaGC.

Objective To construct prokaryotic vector and express human herpes virus 8 (HHV8) small capsid protein open reading frame 65 (ORF65) in Escherichia coli.Methods DNA was extracted from BCB-1 cells (HHV8-positive but EBV-negative).HHV80RF65 coding sequence was amplified by PCR and inserted into the prokaryotic expression vector pThioHisA.Recombinant plasmid was transformed into E.coli BL21 to express fusion protein induced by IPTG.The expressed products were purified by affinity chromatography on Ni-NTA resin.The antigenieity and the specificity of the recombinant proteins was identified by Western blot with HHVS-positive serum samples.ELISA coating with the recombinant proteins was used to screen 568 serum samples,which were simultaneously detected by IFA kit(Biotrin) and ELISA kit(Qiagen).Results Gene sequencing showed that the target gene was identical with that of HHV8 standard species,the 31 500 fusion protein was found in SDS-PAGE.ELISA coating with the recombinant proteins had a good agreement with IFA kit(Biotrin) and ELISA kit(Qiagen).The detection for the clinical samples showed the ELISA kit was feasible,applicable and consistant.Conclusion The recombinant proteins showed good antigenicity,and it is valuable for further study on HHV8 specific antibody detection.

Objective To explore the risk factors and protective factors for stomach cancer in Ganyu county.Methods Data of 319 pairs of new stomach cancer cases and health controls(1:1 matched)were studied by conditional Logistic regression method on the influential factors.Results The main risk factors for stomach cancer were the habits of eating hot foods(OR= 2.21,95%CI:1.57～3.12),the history of upper gastrointestinal inflammation(4.26,2.59～7.03),family history of cancer(2.29, 1.37～3.82);The main protective factors were often eating raw garlic(OR=0.64,95%CI:0.42～0.96),regular drinking tea(0.37, 0.25～0.54).Conclusion Unhealthy dietary habits,the history of upper gastrointestinal inflammation and family history of cancer are related to stomach cancer,while eating raw garlic and regular drinking tea may be effective in preventing the occurrence of stomach cancer.The results could be applied in stomach cancer prevention activities in Ganyu county.
