There were significant difference between ITP group and control group(P

Gallbladder cancer (GBC) is the most common cancer of the biliary tract,constituting 80％-95％ of malignant biliary tract tumors.Surgical resection is currently regarded as the sole curative treatment for GBC.Hepatopancreatoduodenectomy (HPD) has been adopted to remove the advanced gallbladder tumor together with the infiltrated parts within the liver,lower biliary tract and the peripancreatic region of GBC patients.However,patients who underwent HPD were reported to have a distinctly higher postoperative morbidity (71.4％,ranging from 30.8％ to 100％) and mortality (13.2％,ranging from 2.4％ to 46.9％) than those given pancreatoduodenectomy (PD) alone.We present two patients with advanced GBC who underwent a modified surgical approach ofHPD:PD with microwave ablation (MWA) of adjacent liver tissues and the technique of intraductal cooling of major bile ducts.No serious complications like bile leakage,pancreatic fistula,hemorrhage and organ dysfunction,etc.occurred in the two patients.They had a rapid recovery with postoperative hospital stay being 14 days.Application of this approach effectively eliminated tumor-infiltrated adjacent tissues,and maximally reduced the postoperative morbidity and mortality.This modified surgical method is secure and efficacious for the treatment of locally advanced GBC.

Doctor WANG Zhi-zhong in the Southern Song Dynasty proposed the acupoint view of "location of disease", which explained the connotation of acupoints from the angle of clinic. Its meaning included two levels, one level meant pathological change on the body surface, that was the location of acupuncture diagnosis-treatment, and the other one indicated that the body surface which was the reflecting point of pathological change on the distal area or inside the body was the location of acupuncture diagnosis-treatment. The specific connotations of clinical acupoints were: location of pathogenic factors or reflection of pathogenic factors, regularity between acupoints un- der disease and specific organ, morphological differences and positioning variability after acupoints under disease, and acupoints examination, diagnosis and treatment.

Objective To construct pseudotype retrovirus which integrates hemagglutinin(HA)of H5N1 avian influenza virus(AIV)isolated from human in Shenzhen.Methods AIV HA gene was amplified bv RT-PCR,then it was ligated with pGEM-T vector,and identified by restriction enzyme digestion and sequenced.HA gene was cloned into CMV/R vector at the site of Sal Ⅰ and BamH Ⅰ.pHR-Luc,pCMV&8.2 and CMV-HA were co-transfected into 293T cell by co-precipitation with calcium phosphate.The pseudotype virus supernatant was harvested 72 h post-transfection and ultracentrifugation,and the HA and P24 expression on the surface of pseudotype virus was analyzed by western blot.Meanwhile.the infection activity of HIV-HA pseudotype virus was identified in different kinds of cell lines,including MDCK,HeLa,CHO and 293T.Results A/Shenzhen/406H/06 belonged to subclade2.3 with open reading frame(ORF)of HA gene encoded 567 amino acides,whose accession number was EF137706 in GenBank.HA gene was cloned into CMV/R successfully.After co-transfection of above vectors,it revealed that HA protein could integrate pseudotype virus by western blot,and precursor protein HA0 could cleavage into HA1 and HA2 with biological activity.Finally.HIV-HA pseudotype virus could infect 4 kinds of cell lines,which indicated its property of infectivity and catholicity.Conclusion The pseudotype retrnvirns wassuccessfully constructed,which can integrate HA protein of A/Shenzhen/406H/06 and had property of infectivity.It call be used in the further research,including selection of neutralizing antibodies and epitope analysis.

Objective To establish neutralization assay based on H5N1 avian influenza pseudotyped virus in vitro and to evaluate neutralizing titer of convalescent serum from 2 patients with H5N1 avian influenza.Methods pHR-Luc,pCMV△8.2 and CMV/R-SH or CMV/R-TH were cotransfected into 293T cell by co-precipitation with calcium phosphate.Pseudotyped virus supernatant was harvested 72 h posttranofection and identified the expression of HA and P24 by Western blot,and then we analyzed infective activity of 200 μL supernatant of pseudotyped virus.293T cell integrated HA was prepared and anti-HA antibodies in convalescent serum were measured with FACS assay.Neutralizing titers of convalescent serums against Shenzhen and Thailand pseudotyped virus were determined based on calculating IC50 with neutralizing assay.Results Pseudotyped virus involved P24 and HA,and precursor protein HA0 could cleavage into HA1 and HA2 with biological activity.Pseudotyped virus possessed better infective activity,and RLA value was about 2 × 104 with 200 μL supernatant.Both convalescent serums contained anti-HA antibodies and had cross-reactivity against different virus clades with FACS assay.Both convalescent serums had neutralizingactivity and could cross-neutralize different virus clades.However,both serums'neutralizing titers against Shenzhen virus were higher than Thailand.Conclusion We successfully constructed infectious pseudotyped virus which integrated HA of Shenzhen or Thailand virus,and it could be used for evaluation of serum neutralizing activity fast,efficiently and safely with broadly application prospect.

Sailuotong (SLT) is a compound preparation composed of ginseng, ginkgo and saffron for the treatment of vascular dementia In order to identify its material foundation and provide evidence for therapeutic regimen, the pharmacokinetics and brain distribution of ginsenosides were investigated after intragastric administration of SLT. An LC-MS/MS method was developed for the determination of 7 ginsenosides in rat plasma simultaneously. Statistical analysis of obtained data demonstrated that the method has achieved the desired linearity, precision, accuracy and sensitivity. After administration of SLT at 60 mg x kg(-1) dose, 7 ginsengosides were all absorbed into systematic circulation. The quantitative and statistical analysis of gensenosides in plasma showed that protopanaxdiol saponins exhibited higher concentration and longer half life than protopanaxatriol saponins. The mean value of half life of ginsenosides Rg1, Re, Rb1, Rb2/b3, Rc and Rd were 15.26, 2.46, 18.41, 27.70, 21.86 and 61.58 h respectively. The peak concentration of them were 7.15, 2.83, 55.32, 30.22, 21.42, 8.81 microg x L(-1) respectively. The determination of brain distribution at different time after dosing revealed ginsenosides entered into brain promptly but the concentration declined along with time rapidly. The ginsenosides with higher concentration in brain were Rg1, Re, Rb1 and Rc. These findings demonstrated ginsenosides could be absorbed in blood and penetrated into brain rapidly. Some ginsenosides, especially Rg1 and Re, might be the main components directly effecting neurocyte in brain taking advantage of their better brain distribution. While ginsenosides of mostly protopanaxdiol saponins might protect brain mainly depending on peripheral efficacy in virtue of their long residence in blood, by which higher concentration could be reached after multiple dosing.

When looking back to the literature regarding insomnia, it is believed that "disharmony of stomach leads to insomnia" is an important mechanism for the attack of insomnia. This theory is widely accepted in clinical practices by ancient and modern acupuncturists, thus the method treating insomnia from the stomach is developed. But deeper research on its mechanism is still lacking. Through correlation between stomach meridian and heart meridian, spleen and stomach being the pivot of rise and decline of qi movement and yin-yang and being the pivot of five zang-viscera housing spirit, modern abdomen-brain theory and experimental research, the mechanism of treating insomnia from the stomach is discussed in this paper, so as to be better to guide clinical acupoint-selection and treatment.

OBJECTIVETo observe the therapeutic effect of Xinfeng Capsule (XFC) in treating adjuvant arthritis of rats and its effect on fas, fasL and bcl-2 expression in synovial membrane.

METHODSRats were randomly divided into the normal group, the model group, the model group, the methotrexate (MTX) group, the TPT group and the XFC group. Except for the rats in the normal group, animals were modelled to adjuvant arthritis with Freund's complete adjuvant, and the latter three groups were treated with MTX, Tripterygium wilfordii polysaccharide (TPT) and XFC respectively. The arthritis index (AI), change of body weight (BW) of rats were recorded, and the expressions of fas, fasL and bcl-2 in rats' synovial membrane were determined.

RESULTSCompared with before treatment, the AI in the three treated groups was lowered significantly (P < 0.01, P < 0.05). The BW increment in the XFC group after treatment was insignificantly different to that in the normal group (P > 0.05), while it was significantly lower in the other two treated groups than that in the normal group and the XFC group (P < 0.01). Compared with the model group, fasL expression was increased in the XFC group significantly (P < 0.05), but bcl-2 expression decreased, fas expression showed insignificant difference (P > 0.05). Comparison of the three gene expressions between the three treated groups showed no significant difference (P > 0.05).

CONCLUSIONXFC could decrease AI in rats with adjuvant arthritis in the same way as MTX and TPT, it effected better in increasing BW than the latter two. The effect of XFC might be performed by its action in enhancing fasL expression, inhibiting bcl-2 expression and promoting apoptosis of proliferated synovial membranous cell so as to restrain hyperplasia of synovial membrane.
