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.

BACKGROUND: Cone-beam CT (CBCT) and orthopantography are two imaging methods mostly used in the preoperative evaluation of dental implantation. CBCT has high cost and low penetration rate, but orthopantography can result in a larger error in the measurement of bone quantity.OBJECTIVE: To compare the accuracy of bone quantity measurement using CBCT and orthopantography, and to evaluate the clinical effect of simulation in posterior implant region. METHODS: 115 implants from 72 patients undergoing implantation of posterior teeth in the Eye & ENT Hospital of Fudan University were selected. The horizontal heights from the top of the alveolar bone to the important anatomic structures (mandibular nerve or maxillary sinus floor) were measured using CBCT and orthopantography and then analyzed statistically. The implantation simulations were performed using Planmeca Romexis3.8 (for CBCT) and Cliniview9.3 (for orthopantography) to compare the differences in stimulated and postoperative horizontal heights.RESULTS AND CONCLUSION: There were significant differences in the measured data between CBCT and orthopantography (P < 0.05), especially in the maxilla (P < 0.01). There were significant differences between the simulated and postoperative results of the two methods (P < 0.05). The average error and standard deviation in orthopantography were larger than those in CBCT. The average error of implantation simulation using CBCT in the maxilla was smaller than that using orthopantography, whereas the error was similar in mandibular simulations. To conclude, CBCT is more accurate for assessing the quantity of bone in posterior implant region, especially in the maxilla. The accuracy of CBCT and orthopantography in implantation simulation needs to be improved.

Objective To improve the awareness of rare mixed prostatic carcinoma. Methods We reviewed the clinical data of 5 patients with prostatic mixed tumor and relevant literature to ex-plore diagnosis and treatment for it. Results Patient 1 with mixed small cell carcinoma and adeno-carcinoma of the prostate who underwent transurethral electrovaporization of the prostate (TUVP) and flumamide therapy died of lung metastasis 7 months later. Patient 2 with mixed small cell carcinoma and adenocarcinoma of the prostate who underwent TUVP and bilateral testicular resection died of lung metastasis 10 months later. Patient 3 with adenosquamous carcinoma of the prostate who underwent TUVP, radiation therapy and flumamide therapy died of multiple organ failure 8 months later because of the lung, liver, and multiple bone metastasis. Patient 4 with prostatic adenosquamous carcinoma who underwent cystoprostatectomy combined with urinary diversion has already survived for 1 year. Patient 5 with prostatic carcinosarcoma who underwent cystoprostatectomy, urinary diversion, pelvic lymphadenectomy, and radiation therapy died of lung metastasis 13 months later. Conclusion Mixed prostatic carcinoma is quite aggressive with bad prognosis. Its diagnosis relies on detailed pathological examination and immunohistochemical techniques. Patients with prostate adenocarcinoma should be followed up timely after endocrine treatment or radiotherapy. Radical surgery is most effective for mixed prostatic carcinoma.

Objective To observe the myocardial injury attributed to cardiopulmonary resuscitation, and to evaluate the impact of 4 ℃ saline perfusion on the ultra structure of myocardium. Method Twelve Pekimg white swine were induced to make models of ventricular fibrillation by direct current shock. Cardiopulmonary resuscitation was initiated 4 minutes after ventricular fibrillation established, and 10 swine survived from resuscitation. These swine were randomly(random number ) divided into hypothermia group ( n = 5) ( 4 ℃ saline infusion to lower the temperature) and control group ( n = 5). Haemodynamics were monitored. And ultra structure of myocardium was observed under electron microscope 24 hours later. The Mann-Whitney test was used to compare the consecutive variables of 2 samples. Results The damage to the ultra structure of myocardium, myofilaments and mitochondria, was found in the control group, while that to a much lesser extent in the hypothermia group was observed. Conclusions After cardiopulmonary resuscitation, 4 ℃ saline infusion has a protective effect on myocardium.

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

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.

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.

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.
