Objective To investigate the effect of methylprednisolone pulse therapy on spinal nerve functions in patients with acute spinal cord injury (ASCI) and evaluate its safety. Methods 200 patients with ASCI treated in our hospital from January 2010 to December 2016 were selected and were randomly divided into two groups,with 100 cases each group. The patients in control group were treated with routine basic treatment while patients in the study group were treated with methylprednisolone pulse therapy. On the basis of the American spinal cord injury Society scoring criteria (ASIA), the neurological functional recovery scores were performed were scored before and 6 weeks after treatment between the two groups and the adverse reactions were recorded. Results The scores of sensory and motor function of the patients in the two groups were higher than those before the treatment and there was statistical difference (P<0.05), and the scores in the study group was significantly higher than those in the control group, and the difference between the two grouPs was statistically significant (P<0.05). The incidence of adverse reactions in the study group (25.00％) was significantly higher than that in the control group (10.00％), and the difference was statistically significant (P<0.05). The incidence of lung infection and gastrointestinal reaction in the study group were significantly higher than those in the control group and there were statistical difference (P<0.05). Conclusion Methylprednisolone pulse therapy has significant effect on the recovery of neurological function in patients with ASCI, but the incidence of adverse reactions is high, so it is necessary to strengthen the monitoring and intervention in clinic.

Uveitis is a kind of inflammatory disease affected in ocular posterior segment.Uveitis sustains a long duration and causes a significant damage of visual function.It often leads to serious complications,such as cystoid macular edema (CME),cataract,glaucoma,retinal detachment and choroidal neovascularization (CNV).In the pathological process of uveitis,inflammatory factors promote the release of vascular endothelial growth factor (VEGF) through a variety of pathways.It has been verified that VEGF level is elevated in vitreous in the patients with uveiticinduced CME.Intravitreal injection of anti-VEGF drugs,including ranibizumab and bevacizumab,can improve the visual acuity in most patients with noninfectious uveitic-induced CME and CNV.However,intravitreously repeated injections of anti-VEGF drugs may be required in some patients.Intraocular injection of anti-VEGF drugs is an optional and effective way for those with persist macular edema and not being suitable for the use of corticosteroid or immunosuppressive therapy.However,anti-VEGF drugs may affect the efficacy of corticosteroid.Therefore,more clinical and basic researches are still needed.The status and progresses in the use of anti-VEGF drugs for uveitisinduced CME and CNV were reviewed.

Objective The aim of our study was to evaluate the efficacy and safety of tirofiban in patients with acute coronary syndromes with thrombus-containing lesions.Methods We randomized 38 acute coronary syndromes(ACS)patients with thrombus-containing lesions into tirofiban group and control group.In the tirofiban group,10～30 mL of tirofiban was administered intracoronar before and/or after percutanous transluminal coronary angioplasty(PTCA),then stent was implanted as needed.Intravenous tirofiban was used for 24～48 hours after the procedure.In the control group,standard percutanous coronary intervention(PCI)was used for the patients.TIMI thrombosis grade,TIMI blood flow,no reflow and/or slow flow,corrected TIMI frame count(cTFC),myocardial blush grade(MBG),left ventricular eject fraction(LVEF)were measured in the two-dimensions untrasonography;major adverse cardiac events(MACE)and bleeding were observed.Results TIMI thrombosis grade and cTFC decreased more in the tirofiban group than that of the control group[0.90?0.14 vs 1.53?0.54,P

Objective To optimize the extraction conditions of Hyperici Perforate Herba, Coptidis Rhizoma, Schisandrae Chinensis Fructus, and Ziziphi Spinosae Semen forJinzao Yuanzhi Capsule.Methods Hyperin extraction rate was set as index, and HPLC was used for determination. The extraction conditions of ethanol concentration, ethanol quantity, extraction time and other factors were studied with orthogonal test and comparative test.Results Ethanol concentration and extracting times were remarkable factors in the test. The optimum extraction technology forJinzao Yuanzhi Capsule was to reflux and extract the materials with 8 times of 70% ethanol for 2 times, reflux extraction for 1.5 hours, filtration. Then 6 times of 70% ethanol was added for 1.5 hours’ reflux, filtering, and merging extracted liquid.Conclusion The optimum extraction technology is reasonable and feasible.

Objective:Tumor suppressor gene nitrogen permease regulator like 2 (NPRL2), also called tumor suppressor candidate gene 4 (TUSC4), widely exists in all kinds of human tissues and is highly conserved in different kinds of biological species. The expression of NPRL2 is markedly decreased in many human tumor tissues, such as lung cancer, breast cancer,renal carcinoma, et al. NPRL2 is located in human chromosome 3p2.13, and participates in DNA mismatch modification, regulation of signal transduction du-ring cell cycle progression, and apoptosis induction. NPRL2 gene inactivation is related with the initiation and progression of several malignant tumors. The mechanism underlying the tumor-inhibiting activity of NPRL2 gene is not clear and needs to be further investigated.

Aiming at the shortcomings of the traditional nuclear medicine teaching model and attempting to adapt to the needs of the development of clinical nuclear medicine,we changed teaching methods,strengthened practice teaching,performed online learning,introduced the self-made teaching materials,enriched the teaching contents,proposed the concept of comparative imaging and reformed on examination method.These measures greatly improved students' interests in learning and clinical thinking ability and helped students understand and master the theoretical knowledge of medicine.

Objective To observe the protective effect of Ulinastatin in rat islet isolation and advance an improved method in rat pancreas islet isolation.Methods Rat pancreas was perfused with Hanks solution containing collagenase. The rats were divided into 3 group according the Ulinastatin concentrations in collagense: low-concentration Ulinastatin ( 2500 U/ml) group, high-concentration Ulinastatin ( 5000 U/ml) and control group (no Ulinastatin). The isolated pancreases were compared among the groups. Results The shape and number of the isolated pancreases in low-concentration Ulinastatin and high-concentration Ulinastatin groups were superior to those in control group (P

OBJECTIVE:To establish a RP-HPLC method for the determination of capsaicin in Capsicum annuum. METHODS:The determination was performed on Zorbax Eclipse XDB-C18(150 mm?4.6 mm,5 ?m) column with column temperature set at 40 ℃.The mobile phase consisted of acetonitrile and 0.1% phosphate acid solution (45∶55,pH=2.6) with flow rate at 1.0 mL?min-1 and detective wavelength set at 281 nm.RESULTS:The calibration curve of capsaicin was linear over the concentration range of 30～70 mg?L-1(r=0.999 9).The average recovery for capsaicin was 101.33 %(RSD=1.57%,n=9).CONCLUSION:The method is simple,rapid and accurate,and suitable for the determination of capsaicin in Capsicum annuum.
