Objective To assess the safety and effectiveness of neonatal disease screening so as to provide basis for the establishment of a mechanism for managing neonatal disease screening. Methods Using the ideas of evidence-based medicine, a safety and effectiveness assessment of neonatal disease screening was made by means of literature induction. Results The techniques used in neonatal disease screening were highly safe, but their effectiveness was affected by a variety of links and factors. The differences reported in literature in such aspects as blood-collecting time, testing methods, cut-off values, and indexes for outcome evaluation might mean negative impact on the effectiveness. Conclusion More attention ought to be attached to the understanding and assessment of the safety of screening techniques and more efforts need to be made in conducting systematic studies into the effectiveness of screening techniques.

Objective To evaluate the efficacy and safety of Prostant TM in the treatment of chronic prostatitis. Methods A multi center, randomized, double blinded, placebo controlled trial was carried out during March 2001 and May 2001. 72 cases of patients who had been diagnosed as chronic prostatitis were separated into tow groups: 36 cases in the trial group treated with Prostant TM and the other 36 cases in the controlled group using placebo. The efficacy was evaluated by the WBC in EPS and NIH Chronic Prostatitis Symptom Index after a one month follow up. The efficacy of the therapy was divided into four levels:cure,the symptom index score being reduced over 90%, and the number of WBC in the EPS less than 10/HP; effective, the symptom index score being reduced 60%~89% and the number of WBC in the EPS lowered over 50% or less than 15/HP;improved,the symptom index score being reduced 30%~59% and the number of WBC in the EPS lowered over 25%; no effect, the symptom index score being reduced less than 30% or the number of WBC in the EPS lowered no more than 25%. Results All but two cases had completed the follow up.One case (2.8%) was completely cured,remarkable effective in 7 cases (20.0%) of the trial group;and improred in 16 cases (45.7%).Only 2 cases (5.7%)seemed effective and 8 cases (22.8%) improved in the controlled group. The efficacy showed significant difference between these two groups ( P

Objectives To investigate the expression of matrix metalloproteinase-9 (MMP-9) and its tissue inhibitor (TIMP-1) in cutaneous squamous cell carcinomas (SCC) and the relationship between the expression and invasive growth and metastasis of SCC. Methods Immunohistochemical method of streptavidin-peroxidase (SP) was used to detect the expression of MMP-9 and TIMP-1 proteins on the paraffin embedded sections of 65 patients with cutaneous SCC and 5 cases of normal epidermis. The immunohistochemical results were analyzed quantitatively using an image analysis system. Results MMP-9 and TIMP-1 proteins were diffusely expressed on the tumor nests and the mesenchymal cells around the nests, while in normal epidermis MMP-9 and TIMP-1 were weakly positive. The expression level of MMP-9 protein and the ratio of MMP-9/TIMP-1 were higher in aggressive SCC group than those SCC in situ group (t = 2.33 and 2.36, respectively, P

Retroperitoneal laparoscopic live donor nephrectomy offers an intrinsic advantage over conventional transperitoneal laparoscopic nephrectomy because of the potentially lower risk for early and late donor intraperitoneal complications. Herein we presented our experience performing retroperitoneal laparoscopic live donor nephrectomy in 105 donors. All donor nephrectomy was successful. There were no donor deaths and no conversion to open surgery. Mean operation time was 112 min (range, 70-200 min). Intraoperative blood loss was 10-150 mL with an average of 30 mL. Warm ischemia time was 1.3 to 6 min with an average of 3.1 min. Postoperative retroperitoneal hematoma occurred in only one case and there were no other surgical complications. Donors were discharged from the hospital 5 to 10 days postoperation. Average postoperative hospital stay was 6.4 days. One graft was removed due to acute rejection. Delayed graft function occurred in two recipients but renal function returned to normal within four weeks. The other recipients had normal renal function in two weeks except three recipients in four weeks. We believe that retroperitoneal laparoscopic live donor nephrectomy is safe, reliable, and less invasive.

Objective To evaluate the feasibility of perfusion weighted imaging (PWI) in the differentiation of recurrent glioma and radiation-induced brain injuries. Methods Fifteen patients with previously resected and irradiated glioma, presenting newly developed abnormal enhancement, were included in the study. The final diagnosis was determined either histologically or clinicoradiologically. PWI was obtained with a gradient echo echo-planar-imaging (GRE-EPI) sequence. The normalized rCBV ratio[CBV(abnormal enhancement)/CBV(contralateral tissue)], rCBF ratio[CBF(abnormal enhancement)/CBF(contralateral tissue)]and rMTT ratio[(MTT abnormal enhancement)/MTT(contralateral tissue)]were calculated, respectively. The regions of interest (ROIs) consisting of 20-40 mm2 were placed in the abnormal enhanced areas on postcontrast T1-weighted images. Ten to fifteen ROIs measurements were performed in each lesion and the mean value was obtained. Mann-Whitney test was used to determine whether there was a difference in the rCBV/rCBF/MTT ratios between glioma recurrence and radiated injuries. Results Nine of the 15 patients were proved recurrent glioma,6 were proved radiation-induced brain injuries. The mean rCBV ratio[2.87(0.70-4.91)]in glioma recurrence was markedly higher than that[0.70(0.12-1.62)]in radiation injuries (Z=-2.55,P<0.05). The mean rCBF ratio[1.89(0.64-3.96)]in glioma recurrence was markedly higher than that[0.56(0.12-2.08)]in radiation injuries (Z=-2.08,P<0.05). The areas under rCBV and rCBF ROC curve were 0.893 and 0.821. If the rCBV ratio ≤0.77, the diagnosis sensitivity of radiation-induced brain injuries was 100.0%;If ≥2.44, the diagnosis specificity of recurrent glioma was 100.0%. Conclusion PWI was an effective technique in distinguishing glioma recurrence from radiation injuries and rCBV and rCBF ratios were of great value in the differentiation.

The establishment of in vitro model will provide optimal conditions for the study of human papillomavirus (HPV)-associated cervical cancer. In this study, E6 and E7 gens of HPV31 were cloned and expressed in E. coli. The recombinant proteins were purified and used as antigens to immunize mice for the production of polyclonal antibody. Mammalian expression plasmid pBudCE4. 1-HPV31-E6/E7 was also constructed and transfected into C33A cells. The transfected cells were then selected by Zeocin. The expressions of the E6 and E7 mRNAs and proteins were detected by RT-PCR and Western blot respectively. A stable cervical cancer cell line was established as an in vitro model for the study of human papillomavirus type 31(HPV31) associated cervical cancer.
