Objective To study the changes of interleukin-4(IL-4),IL-6,IL-8 in children with idiopathic thrombocytopenic purpura(ITP).Methods The serum of IL-4,IL-6,IL-8 in 35 ITP patients and 20 normal control children were detected by enzyme-linked immunosorbent assay.Results The serum IL-4,IL-6,IL-8 in ITP patients were elevated. 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.

Multimedia computing technology teaching is a new kind teaching method. It conquers many shortcomings such as poor video, poor expression in traditional teaching of microbiology. But it can also strangle the improvising creation of different teachers in teaching and then lead it to be typical " computer teaching" . So we should obey the teaching discipline in making multimedia computing technology courseware. It can lead many sections part from the class teaching if just emphasize the full use of video and audio. We should make the purpose obviously, and make it as easy as possible in teaching, and we should also explore the fixed regularity to make the teaching and studying integrated perfectly.

Microbe cell-surface engineering , which use the microbe cell surface display technology to display foreign proteins on the microbe cell surface to produce cell-surface proteins, was developed in recent years. I t can be utilizedto develop cell-catalyst, cell-adsorbent , live vaccine, biosensor and so on, and have a wide application perspective. But in our county, the microbe cell-surface engineering is studied just now. This review explain the development of the microbe cell surface engineering, overview the study and progress of microbe cell-surface engineering, and look this technology into the future.

In order to isolate genes related with the osmoadaptation and glycerol metabolism of Candida glycerinogenes, a transformation system based on the dominant selectable marker Zeocin and restriction enzyme-mediated integration (REMI) was established. Effects of seven restriction enzymes on transformation efficiency of C.glycerinogenes were tested. Transformation conditions were optimized in the presence of Hind III. Under the optimal conditions of OD_ 600 ≈1.3, voltage of 1.5 kV, 2.0?10~9 competent cells/mL, 100 units of Hind III added, the transformation efficiency was up to 129 trnaformants/?g DNA. 58% of transformants were stable on nonselective medium. These results suggest that REMI technique would be beneficial to the genetic transformation of C.glycerinogenes.

Objective To investigate the point mutations within the adenosine triphosphate-binding region of BCR/ABL in patients with chronic myeloid leukemia who develop imatinib resistance.Methods We collected a total of 17 bone marrow samples obtained from 11 patients who showed hematology resistance (n = 7)or cytogenetic refractoriness(n = 4).A long semi-nest PCR method was used to amplify the ABL kinase domain of the BCR/ABL allele.After two rounds of PCR reactions,we got a fragment of 863 bases The PCR products were purified and followed by sequencing.Results In total,we find three point mutations presented in all patients tested G250E,E255K and T315I.The mutation rate of hematology resistance is 4/ 7,and 95% confidence interval was 8%-90%,while mutation rate of cytogenetic refractoriness 1/4,95% confidence interval 1%-81%.For those patients whose samples were available,no single mutation were determined before imatinib resistance emerged.Conclusions There is high frequency of point mutations clustered within the adenosine triphosphate-binding region of BCR/ABL in patients with chronic myeloid leukemia.It's good for patients to switch to another therapeutic strategy when the mutations are detected.

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.
