Objective To research the relationship among the disc protrusion on MRI, sex, age, course and the clinical types. Methods MRI was performed for 102 patients. The disc protrusion was divided into three types. According to clinical types, the patients were divided into four types. Statistically, age, course, clinical type and protrusion on MRI were analyzed by SPSS13.0. Results The age was not related with the clinical types and disc protrusion on MRI. There were obvious relations between clinical types and course. There were obvious relations between clinical types and disc protrusion. Conclusion The clinical types are very important on diagnosis of disease stages and choice of therapy in treating lumbar disc protrusion.

Epidemiological surveys show that folic acid can prevent prostate cancer, but fortified folic acid may increase the risk of the malignancy. The physician data queries from the National Cancer Institute of the USA describe folate as protective against prostate cancer, whereas its synthetic analog, folic acid, is considered to increase prostate cancer risk when taken at levels easily achievable by eating fortified food or taking over-the-counter supplements. We review the current literature to examine the effects of folate and folic acid on prostate cancer, help interpret previous epidemiologic data, and provide a clarification regarding the apparently opposing roles of folate for patients with prostate cancer. A literature search was conducted in Medline to identify studies investigating the effect of nutrition and specifically folate and folic acid on prostate carcinogenesis and progression. In addition, the National Health and Nutrition Examination Survey database was analyzed for the trends in serum folate levels before and after mandatory fortification. Folate likely plays a dual role in prostate carcinogenesis. There remains some conflicting epidemiologic evidence regarding folate and prostate cancer risk. However, there is growing experimental evidence that higher circulating folate levels can contribute to prostate cancer progression. Further research is needed to clarify these complex relationships.

Objective To evaluate the efficacy and safety of trimebutine combined with mosapride on functional dyspepsia. Methods Patients with functional dyspepsia were randomly divided into three clinical groups. Group A (n=116) received 0.2 g trimebutine after meal,group the drug combination B (n=116) received 5 mg mosapride before meal,and the drug combination group (n=115) received 0. 2 g trimebutine after meal plus 5 mg mosapride before meal. All medications were taken orally three times daily for 4 weeks. Improvement in clinical symptoms and adverse reactions in each group were evaluated at the end of study. Results A total of 339 patients among 347 enrollees completed the treatment and follow-up. The clinical efficacy on postprandial fullness, early satiation, epigastric pain, epigastric burning, upper abdominal bloating and nausea were 88. 4%,76. 9%,72. 9%,61. 8%,86. 7% and 81. 7%,respectively in the drug combination group after 4-week treatment,which were superior to those in group A or B (P<0. 05) except for epigastric burning. The total effective rate of the drug combination group was 78. 8%,significantly higher than the other two groups (P<0. 05). The total incidence of side effects in the drug combination group was 1. 8%,similar to that of group A and B (1. 8% and 0. 9%,respectively, P =0. 776). Conclusion Trimebutine combined with mosapride is safe and effective for improving symptoms in functional dyspepsia.

ObjectiveTo explore the diagnosis and treatment of acute mesenteric ischemia.MethodsClinical data of 12 cases with acute mesenteric ischemia diagnosed by both operation and pathology were analyzed retrospectively.ResultsThe cases were mainly aged patients accompanied by cardiovascular disease and easily developed to strangulative intestinal obstruction. The mortality rate of this disease was very high.ConclusionThe early diagnosis with suitable techniques and prompt treatment are the keys to the management of this disease.

OBJECTIVETo observe clinical efficacy in treating cutaneous deficiency of traumatic shank amputation stump with full-thickness skin graft combined with vacuum sealing drainage.

METHODSFrom September 2009 to December 2012, 15 patients with cutaneous deficiency of traumatic shank amputation stump were treated with full-thickness skin graft combined with vacuum sealing drainage. Among patients, there were 11 males and 4 females with an average age of 41.5 (ranged from 25 to 62) years old. Ten cases were caused by traffic accident and 5 cases were caused by heavy object, 9 cases on left and 6 cases on right. Six patients with smashed wound were treated with debridement and amputation, combined with vacuum aspiration in-emergency; 9 patients caused by infection and necrosis were treated with debridement and amputation, combined with vacuum aspiration, and full-thickness skin graft were performed at stage II. The skin defect area of residual limbs ranged from 40 cm x 20 cm to 25 cm x 15 cm.

RESULTSAll patients were followed up from 3 months to 1 year. Full-thickness skin graft of residual limbs were survived,and obtained satisfactory walking function with prosthetic. Residual skin increased thicken, wearproof without rupture and pain.

CONCLUSIONFull-thickness skin graft combined with vacuum sealing drainage in treating cutaneous deficiency of traumatic shank amputation stump could reserve the length of residual limbs, increase survival rate of skin graft with less scar of survival skin, get good wearability and it is conducive to prosthetic wear. It is a simple and easy treatment method.

BACKGROUND: Peri-implant crestal bone resorption is considered as a normal reaction according to traditional butt-joint prosthesis around two-piece implants. OBJECTIVE: To evaluate bone loss around two-piece implants restored according to the platform switching concept in the posterior area of the mandible. METHODS: Eighty-eight implants were consecutively placed in 50 patients following submerged surgical protocol. In the test group, 40 Ankylos implants were placed using platform switching technique, while 48 3i implants using traditional butt-joint in the control group. All the implants were positioned at the crestal level. Definitive prosthesis was delivered after 3 months. RESULTS AND CONCLUSION: All implants were judged to be successfully osseointegrated. The success rate was 100%. Twelve months after restoration, radiographic analysis showed an average bone reduction level of (0.31±0.39) mm in the test group that was statistically significantly different (P < 0.01) from the average reduction in the control group [(0.94±0.43) mm]. In the follow-up time, no implants were loose or lost and healthy gingival was seen. These findings show that the platform switching technique can reduce peri-implant crestal bone resorption and preserve alveolar bone level around dental implants 12 months after restoration.Oral Implantology Center, Affiliated Hospital of Medical College, Qingdao University, Qingdao 266003, Shandong Province, China

Objective To investigate the inducing effects of selenium dioxide(SeO2 ) on the apoptosis in human cervical carcino-ma cell line Hela and its influence on the expression of apoptosis-related proteins caspase-3 and P53 .Methods Hela cells were trea-ted with different concentrations of SeO2 for 24 h in vitro ;the morphological changes of Hela cells were observed by the optical mi-croscope;the influence of SeO2 on the cell proliferation and vitality was examined by the MTT assay ;the flow cytometry was em-ployed to detect the cell apoptosis rate ;the expressions of caspase-3 and P53 proteins in Hela cells were determined by the Western blot analysis .Results Under the optical microscopy ,SeO2 generated the obvious influence on the cell growth morphology ,a large number of cells became rounded and shrunken ,and lost the normal form ,while the adherence cell number was evidently decreased and the proliferation was slowed down ;the MTT results showed that SeO2 markedly inhibited the cell proliferation and viability in a dose-dependent manner ,in which ,the cell apoptosis rates induced by the 0 ,1 .875 ,3 .750 ,7 .500 ,15 .000 and 30 .000 μmol/L con-centrations of SeO2 were 3 .12% ,30 .56% ,33 .42% ,37 .50% ,45 .43% and 69 .38% respectively ,which revealing the obviously in-creasing trend;the Western blot assay revealed that SeO2 could up-regulate the caspase-3 and P53 levels ,and reached the peak value at the concentration of 7 .500μmol/L .Conclusion SeO2 could induce the cervical cancer cell apoptosis possibly by up-regulating the expressions of caspase-3 and p53 in Hela cells .

Multi-target drugs attract increasing attentions for the therapy of complicated neurodegenerative diseases. In this study, a computer-assisted strategy was applied to search for multi-target compounds by the pharmacophore matching. This strategy has been successfully used to design dual-target inhibitor models against both the acetylcholinesterase (AChE) and poly (ADP-ribose) polymerase-1 (PARP-1). Based on two pharmacophore models matching and physicochemical properties filtering, one hit was identified which could inhibit AChE with IC50 value of (0.337 +/- 0.052) micromol x L(-1) and PARP-1 by 24.6% at 1 micromol x L(-1).
