15 consecutive eyes of 13 patients with kerato- conus were treated with radial keratotomy and follo- wed up periodically about 1 year.The visual acuity of all eyes was improved significantly,in the early stage after surgey.The 12 eyes were examined one year postoperatively,1 eye maintainning good result,5 eyes obtainning some improvement of vision and flatt- ening of central cornea,6 eyes of which 4 had adv- anced corncal cones gainning no visual benefit from the surgery.Radial keratoto my appears to be effec- tive in early case of keratoconus,however the long- term result is still not known.

Magnetic compression anastomosis (MCA)involves the use of two rare-earth magnets that attract to each other transmurally between two internal organs, resulting in compression and subsequent fistula formation to create a nonsurgical enteric, vascular, or biliary anastomosis with therapeutic aims. The magnetic vascular coupler allows a sutureless anastomoses between arteries and veins by using interventional radiological techniques. The MCA technique significantly reduces ischemic time during anastomosis, and has the advantages of low invasiveness and simplicity. It is a rather effective method for recanalizing between various hollow viscera, creating anastomosis such as gastrojejunostomy, choledochojejunostomy, or choledochoduodenostomy.Furthermore, this novel technique is considered to be a feasible and alternative reconstructive method for patients who develop significant bile duct complications following hepaticojejunostomy and living donor liver transplantation. MCA is a promising and novel technique in the further development of minimal invasive surgery.

Hydroxypropyl methylcellulose (HPMC) propels self-emulsifying drug delivery systems (SEDDS) to achieve the supersaturated state in gastrointestinal tract, which possesses important significance to enhance oral absorption for poorly water-soluble drugs. This study investigated capacities and mechanisms of HPMC with different viscosities (K4M, K15M and K100M) to inhibit drug precipitation of SEDDS in the simulated gastrointestinal tract environment in vitro. The results showed that HPMC inhibited drug precipitation during the dispersion of SEDDS under gastric conditions by inhibiting the formation of crystal nucleus and the growth of crystals. HPMC had evident effects on the rate of SEDDS lipolysis and benefited the distribution of drug molecules across into the aqueous phase and the decrease of drug sediment. The mechanisms were related to the formed network of HPMC and its viscosities and molecular weight. These results offered a reference for selecting appropriate type of HPMC as the precipitation inhibitor of supersaturatable SEDDS.

Guided by good clinical practice ( GCP) , M hospital cooperated with the Ethics Committee in quali-ty management of clinical trials and took the specific measures including perfecting the institution and standard op-erating procedures, implementing three level quality control institution, strengthening the training of GCP, and closely cooperating with drug and data management of clinical trials, quality control in the clinical trial, ethical re-view and supervision, quality control in the whole process (seamless connection). Seamless connection from the beginning of project acceptance and quality control in the whole process of clinical trials can effectively solve the ex-isting problems in clinical trials and improve the quality of clinical trials.

Objective To explore the applied value of MRI in diagnosing pyogenic of infection of gluteus muscles.Methods MRI data in 9 cases with pyogenic infection of gluteus muscles proved by operation or biopsy were retrospectively analysed by comparison with the pathological diagnosis.Results The pyogenic infections localized at unilateral gluteus muscles involving single,two or three gluteus muscles in all cases.On MRI,the infective gluteus muscles were swelling diffusely and the infections developed along the long axis of the muscles and most or all gluteus muscles were involved.4 cases appeared as suppurative myositis and 5 cases developed typical abscess.4 cases were accompanied with subcutaneous edema and the abscess broken into skin in one case.Conclusion The pathological characteristics of the stage and extent of the pyogenic infection in gluteus muscles can be displayed by MR imaging.

Objective To investigate whether SUMO-1 enhances the apoptosis induced by wild-type p53 plasmid transfection in HepG2 cells. Methods The HepG2 cells were transfected respectively or simultaneouly with the following expressional plasmids as pcDNA3-wtp53(pwtp53,including human wild-type p53 gene),pCMV-HDM1B(pMDM2,including HDM2 gene, homologous gene as murine double minute gene 2),pcDNA3-His6-SUMO-1(pSUMO-1 ,including small ubiquitin-like modifier-1 gene)and plasmid pcDNA3.The proteins expressed in cells were detected by means of Western blotting and the apoptosis rates of cells were measured by flow cytometry. Results The protein bands of p53 and MDM2 could be seen in cells transfected with pwtp53 and pMDM2. Meanwhile,the relative larger molecular weight bands were also seen in cells transfected with pSUMO-1 which represented the p53 and MDM2 protein modification by SUMO-1. Merely the trace of p53 protein was detected in cells not transfected with any plasmid or only transfected with empty plasmid and pSUMO-1. In cells transfected with pwtp53 and pwtp53+pSUMO-1,the apoptosis rates were (16.79?1.62)% and (18.15?1.36)%. When transfected with pwtp53+pMDM2,the rate decreased to (5.17?1.23)%. The apoptosis rate would come up again to (14.06?1.84)% after transfected with pwtp53+pMDM2+pSUMO-1 and the difference of rates were significant compared to the cells transfected with pwtp53+pMDM2 (P

Recent studies about the GCT are focusing on searching for new standards and indexes to prognose the biological behavior of the GCT because of the traditional standards and indexes have been realized often not agree with to the clinic. we review the lately research about the biological behavior of the GCT, then analyse and sum up the correlative indexes that could be significant in studying the prognosis of the GCT.

It is estimated that there are about 0. 17 billion HCV infection cases worldwide. HCV sub-genotype 1b and 2a have been the most common genotypes found in the mainland China. The positive rate of HCV antigen in hepatocellular carcinoma (HCC)/corresponding non-cancer liver tissues in China is between 36. 2% (25/69)-72. 7% (48/66), which is associated with different detection methods. HCV associated HCC usually occurs along with chronic hepatitis→cirrhosis pathway. There was no doubt a correlation between the expression of HCV antigen and liver cell transformation, and the change of the functions of tumor-associated genes. These results show HCV is an important risk factor for development of HCC.
