AlM: To study the clinical effect of the application of microscopic pterygium resection combined with different concentration of mitomycin C ( MMC) .
METHODS:A total of 110 cases of pterygium patients (120 eyes) were randomly divided into control group (58 eyes) and observation group (62 eyes) according to the odd and even number method. The control group adopted the pterygium resection combined 0. 3mg/mL MMC, and the observation group was given pterygium resection combined 0. 2mg/mL MMC. The cure rate and the recurrence rate, eyesight before and after the treatment, two groups of cornea and sclera wound healing situation, the incidence of postoperative complications were compared.
RESULTS: The cure rate and recurrence rate of the control group was 84. 5% and 15. 5% respectively, and the observation group was 93. 6% and 6. 5% respectively, the differences were statistically significant (P<0. 05). There were statistical differences of vision of the two groups before and after treatment (P<0. 05), and there were no statistical differences of the two groups between the two groups after treatment (P>0. 05). The cornea, sclera, wound healing time of the observation group were less than the control group, and there were statistical differences between the two groups ( P < 0. 05 ). The incidence of complications was 13. 8% in the control group and 3. 2% in observation group, with statistically significant difference (P<0. 05).
CONCLUSlON: The application effect of microscopic pterygium resection combined with MMC is remarkable, and the joint of 0. 2mg/mL concentration of MMC is more safe and effective, and is worth popularizing in clinical application.

Objective To investigate the antitumor therapeutic effect of combined therapy of magnetic induction heating by nano-magnetic particles, herpes simplex virus thymidine kinase gene(HSV-tk suicide gene) and internal radiation in mice bearing MCF-7 breast carcinoma. Methods The transfection reagents, plasmids heat shock protein-HSV-tk (pHSP-HSV-tk), ferroso-ferric oxide nano-magnetic fluid flow and 188Re-ganciclovir-bovine serum albumin-nanopaticles (GCV-BSA-NP) were prepared. The heating experiments in vivo were carried out using ferroso-ferric oxide nano-magnetic fluid flow. Sixty mice tumor models bearing MCF-7 breast carcinoma were established and randomly divided into six groups. Group A was the control group, B was gene transfection therapy group, C was hyperthermia group, D was gene transfection therapy combined with radionuclide brachytherapy group, E was gene therapy combined with hyperthermia group, and F was gene therapy, hyperthermia combined with radionuclide brachytherapy group. The tumor growth, tumor mass and histopathological changes were evaluated. The expression of HSV-tk in the groups of B, D, E and F was detected by RT-PCR. Poisson distribution and one-way analysis of variance (ANOVA) were used for statistical analysis by SPSS 10.0 software. Results In the animal heating experiments, the temperature of tumor increased up to 39.6 ℃, 43.2 ℃, and 48.1 ℃ quickly with different injected doses (2, 4 and 6 mg respectively) of nano-magnetic particles and maintained for 40 min. The temperature of tumor tissue reduced to 36.8 ℃, 37.5 ℃ and 37.8 ℃ in 10 min when alternating magnetic field (AMF) stopped. The tumor mass in Groups C ((452.50 ±30.29) mg), D ((240.98 ±35.32)mg), E((231.87 ±27.41) mg) and F ((141.55 ±23.78) mg) were much lower than that in Group A ((719.12±22.65) mg) (F=800.07, P＜0. 01), with the most significant treatment effect in Group F.The tumor mass in Group B((684.05 ±24.02) mg) was higher than that in Group D (t =32. 805, P ＜0. 05). Semi-quantitative RT-PCR analysis showed that the expression of HSV-tk in Groups B and D (0.33 ±0. 13 and 0. 46 ±0.12) was significantly different from that in Groups E and F (0.66 ±0.13 and 0.74 ±0. 11)(F = 21. 573, P ＜ 0.05). Conclusion Combined use of hyperthermia, gene therapy and radionuclide brachytherapy could effectively depress the growth of MCF-7 breast carcinoma, thus possessing treatment potential for this tumor.

Zhangjiagang Hospital of Traditional Chinese Medicine, as a collaborative unit of the project, participated in the clinical consistency evaluation in project of TCM Practice guidelines for Prevention and Treatment of Biqiu (allergic rhinitis) organized by the State Administration of Traditional Chinese Medicine. The evaluation results showed that the guideline met the clinical practice requirements. This article summarized the clinical evaluation experience from the three aspects: The diagnosis in TCM and Western medicine is clear and definite, but the English translation needs to be considered; The definition of remission phase of Biqiu (allergic rhinitis) is difficult, to interfere by identifying the constitution is innovative; The advantages of "preventive treatment of diseases" in TCM should be fully played in role, improving the satisfaction of patients.

OBJECTIVETo investigate the influence of hepatitis C virus (HCV) serotype on the interferon (IFN) treatment of patients with chronic hepatitis C.

METHODSNinety-eight patients with chronic hepatitis C were divided into two groups: patients in group 1 (n=53) were treated with Pegasys, 180 ug injected subcutaneously once a week for 24 weeks, and those in group 2 (n=45) were injected with Roferon-A 3 MU three times a week for 24 weeks and then patients in both groups were followed up for another 24 weeks. The virological response at the end of follow up was the primary endpoint for evaluating the effects of IFN treatment. The HCV RNA levels of the chronic hepatitis C patients were determined with COBAS AMPLICOR MONITOR Test, version 2.0, and the HCV serotypes were examined by the means of ELISA using Murex HCV Serotyping 1-6 Assay.

RESULTSOf the 98 cases, HCV in 44 cases was serotype 1, in 23 was serotype 2, in 10 was serotype 3, in 1 was serotype 4, 1 was serotype 5 and in 2 was serotype 6; HCV serotypes in the remaining 17 patients could not determined. In Pegasys treatment group, the biochemical and virological response was not significantly different at the end of treatment between the patients with serotype 1 and non serotype 1 or serotype undetermined patients, but the sustained virological response rate of HCV serotype undetermined group (66.7 percent) was significantly higher than that of serotype 1 patients (27.3 percent) (p=0.035). In Roferon-A treatment group, the virological response rate at 24 weeks and sustained viral response rate at the end of follow-up was not significantly different between serotype 1 and non serotype 1 patients or serotype undetermined patients.

CONCLUSIONAfter the six months treatment course, the HCV serotype had some effects on the treatment response to Pegasys treatment for chronic hepatitic C.

OBJECTIVETo investigate the effect of Deferasirox on the micro-angiogenesis in narrow pedicle flap through Epithelial-Mesenchymal Transition.

METHODS32 male rats were randomly divided into group I and II which were subdivided into Ia and Ib, IIa and IIb, 8 rats in each group. The rats were administrated intragastrically for 7 days with Deferasirox 100 mg/kg in group Ia and IIa, with the same dose of N. S. in group Ib and IIb. After that, narrow pedicle flaps were formed on the rats back. In group I, the subcutaneous vascular network was observed intraoperatively. The flap survival rate was recorded. In group II , specimens were collected at the distal end of flaps 3 days after operation. IHC and Western Blot were done to examine the expression of CD34, E-cadherin, Vimentin. The microvessel density was also calculated.

RESULTSThe subcutaneous micro-angiogenesis in group Ia was more exuberant than that in group Ib. The narrow pedicle flaps in group Ia survived completely, while the survival rate was 62.5% in group Ib (P < 0.05). The percentage of flap survival area for Ia and Ib was (100 +/- 0.00) % and (84.06 +/- 4.42)% (P < 0.05). The expression of E-cadherin in IIa was lower than that in IIb, while the expression of Vimentin and CD34 were higher in IIa, showing statistically difference (P < 0.05).

CONCLUSIONDeferasirox can improve the flap micro-angiogenesis through inducing epithelial-mesenchymal transition, so as to improve the survival rate of narrow pedicle flap.

To clone mouse phage antibodies against H-Y antigen from a phage antibody library, three cycles of affinity enrichment of the mouse phage antibody library with male spleen cells and two cycles of nonspecific absorption with female spleen cells were performed. The presence of mouse Fab on the phage surface was determined by ELISA and sequence analysis. 9 of 15 strains can bind to male spleen cells with the specific activity. Recombination rate of the phage antibody library clones is 60%. Sequence analysis of the PCR products of plasmid DNA of E5 clones show VH and Vkappa had common characteristics shared by other known variable region of antibodies. The mouse phage Fab antibody could be used for identifying H-Y antigen, and for the development of sex determination of early embryos in mammals.

BACKGROUNDTo study the predictive factors associated with clinical deterioration in SARS patients.

METHODSThe clinical data of 60 SARS patients were analyzed by logistic regression and Cox's proportional hazards analysis.

RESULTSIn logistic regression models, both older age (P=0.009) and severe lymphopenia (P=0.004) were significant predictors of clinical deterioration. In Cox's proportional hazard models, severe lymphopenia was significant predictor associated with prolongation of stay in hospital.

CONCLUSIONOlder age and severe lymphopenia seem to be statistically significant for predicting the clinical deterioration in SARS patients.
