Objective To explore whether PI3K/ AKT signaling pathway participates in the inhibiting effect of Ru-tin on H2 O2-induced apoptosis in human lens epithelial cells( HLEC). Methods HLEC were divided into four groups: control group,H2 O2 group,rutin group,LY294002 group. Cell survival rates were determined by a 3-(4,5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) assay; cell apoptosis rates were monitored by flow cytometry with Annexin V-FITC and propidiun iodide(PI) staining. Western blot was used to measure the expres-sion levels of AKT and p-AKT. Results H2 O2 induced HLEC apoptosis. Compared with H2 O2 group,rutin group not only increased the expression lever of p-AKT,but also reduced cell apoptosis rate(P < 0. 01). In LY294002 group, LY294002, an inhibitor of PI3K/ AKT signaling pathway,could significantly block the change of these inde-xes produced by rutin group(P < 0. 01), but no significant change compared with H2 O2 group. Conclusion Rutin inhibits H2 O2-induced cell apoptosis and may be associated with PI3K/ AKT signaling pathway.

Sepsis is featured with acute onset, rapid progress and high mortality.Because its clinical manifestations is very similar to noninfectious systemic inflammatory response syndrome, it is difficult to diffferentiate the two diseases, which results in delayed use or abuse of anti-infective drugs.Procalcitonin is widely recognized as a sepsis biomarker, but it has its limits.Procalcitonin must be interpreted cautiously, in conjunction with the clinical picture.Dynamic monitoring of procalcitonin can give clinicians more help.

Long non-coding RNAs ( lncRNAs) are a class of RNA molecules which are unable to codify proteins. They express abnormally in tumor cells including prostate cancer cells and play a significant role in development of tumor. Some lncRNAs have been proven to affect physiological processes of prostate cells and act as tumor suppressor or activator and could be regulated through several methods. Thus, lncRNAs have the potential to be therapeutic targets of prostate cancer. This review introduces expressed abnormally ln-cRNAs in prostate cancer and their functions and mechanisms in prostate cancer.

OBJECTIVE:To establish a method for the determination of EPA and DHA in ray oil.METHODS:The determination was carried out on Diamonsil C18 column.The mobile phase consisted of acetonitrile-water(95 :5) with flow rate of 1.0 mL?min-1 and detection wavelength set at 220 nm.The column temperature was set at 25 ℃.RESULTS:The linear ranges were 1～4 ?g for EPA(r=0.999 1) and 2～8 ?g for DHA(r=0.999 4).The average recoveries were 99.23% for EPA(RSD=0.49%) and 99.30% for DHA(RSD=0.27%).CONCLUSION:The method is simple,rapid,accurate and reproducible for the detection of EPA and DHA in ray oil.

OBJECTIVE:To investigate the anti-angiogenic activity of ray cartilage glycosaminoglycans(RCG).METHODS:Primary culture of human umbilical vein endothelial cells(HUVEC)was performed,and MTT was adopted to evaluate the effects of RCG on the proliferation of HUVEC;Corneal neovascularization(CNV)was induced by sutures on Wistar rats,and CNV area was calculated to evaluate the effects of different concentration of RCG on CNV in Wistar rats.The model of mice with Lewis lung carcinoma was made to observe the effects of different concentration of RCG on tumor growth,with inhibition ratio of primary tumor measured and microvessel density(MVD)quantitated by immunohistochemical staining.RESULTS:RCG obviously inhibited the proliferation of HUVEC in vitro,with IC50 value at 62.93 mg?mL-1.As compared with normal saline group,RCG groups showed smaller areas of new blood vessels(P

Objective To inustigate oceular blood flow velocity in the eyes of paicients with diabetic retino pathy.Methods Hemodynamic parameters in the ophthalmic arteny(OA),central retinal artery(CRA) were determined with color Doppler sonography(CDS) in 70 eyes of 35 patients with diabetic retinopathy and 80 eyes of 40 patients of mormal controlts.Results Compared with normal subjects,the patients with diabetic retinopathy showed significant slower hemodynamic pararneters with OA.CRA and higher with resistive index(P

Objective To compare the clinical efficacy of low temperature-controlled plasma radio frequency ablation by nasal endoscopy with traditional way in treatment of nasal vestibular cyst. Methods 68 patients with nasal vestibular cyst from January 2010 to January 2016 were selected and randomly divided into control group and observation group, with 34 cases in each group. The control group received traditional way (labiogingival groove approach), while the observation group received low temperature-controlled plasma radio frequency ablation by nasal endoscopy. The operating time, introoperative blood loss, postoperative incision pain, wound healing time and complications were compared between the two groups. Results The operating time, introoperative blood loss, postoperative incision pain,wound healing time of observation group were significantly lower than that in control group (P < 0.05). The complication in observation group was lower than that in control group (P < 0.05). Conclusions The low temperature-controlled plasma radio frequency ablation by nasal endoscopy holds many advantages: less pain, good efficacy, simple manipulation and lower complications. Therefore, it is worthy of promoting clinical application.

Methods 42 patients with tongue base cysts from January 2013 to December 2014 were randomly divided into treatment group and control group, the treatment group underwent microlaryngoscopy radiofrequency treatment, the control group underwent direct laryngoscopy under the tongue cystectomy, then the operation time, blood loss and postoperative recurrence rate were observed and recorded, and self-evaluation method using visual analog (VAS) to evaluate the effect of surgery. Results The operative time of treatment group was significantly shorter, and the blood loss was significantly less than the control group, the difference between the two groups was statistically significant (P < 0.01); for 1-year follow-up, six-month recurrence rate in control group was 9.52%, the treatment group had no recurrence cases, the difference was not statistically significant (P > 0.05); 12 months, the recurrence rate was 28.57% in the control group, the treatment group, the recurrence rate was 4.76%, the difference between the two groups was statistically significant (P < 0.05); Preoperative VAS score of the two groups have no significant difference, while after surgery, the VAS scores' difference was statistically significant, even treatment group compared with the control group VAS scores after surgery was statistically significant (P < 0.01). Conclusion Microlaryngoscopy radiofrequency in treatment of tongue base cysts have advantages of significant efficacy, safe and reliable, It's worthy of clinical promoting.

BACKGROUND:With the development of sports medicine and research of patel ofemoral disorder, patel a alta has been paid increasing attention as the exact pathogenesis of patel ofemoral disorder. There are many radiographic measurement indexes of patel a alta. A large number of clinicians and radiography physicians are trying to diagnose and treat this disease as early as possible.
OBJECTIVE:To review the radiographic measurement and research progress of patel a alta, find out the advantages and disadvantages of different indexes, and look into the future development prospects.
METHODS:A computer-based online search of Pubmed and CNKI databases between 1989 and 2013 was performed for articles addressing radiographic diagnose and measurement patel a alta. The key words were“patel a alta, patel a height, measurement, diagnosis”in English and“patel a alta, patel a height, patel a position, diagnosis, measurement”in Chinese.
RESULTS AND CONCLUSION:Now there are many measurement indexes of patel a alta and they are divided into two groups:indirect index and direct index. The indirect index measures the relative location of patel a and tibia, such as Insal-Salvat index, Blackburne-Peel index, and Caton-Deschamps index. The direct index measures the relative location of patel a and femur, such as patel otrochlear index, and patel ophyseal index. The latest study indicates that the biomechanics of patel ofemoral joint is the key to understand the pathogenesis of patel ofemoral disorder. As the MRI technique develops, direct index for the location of articular cartilage of patel ofemoral joint, such as patel otrochlear index, seems to be the best measurement to patel a alta. However we stil have many problems in the study of patel otrochlear index.
