2.Research progress in topical application of anti-vascular endothelial growth factor drugs for uveitis-associated cystoid macular edema and choroidal neovascularization
Chinese Journal of Experimental Ophthalmology 2014;32(7):659-663
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.
3.Effect and safety of methylprednisolone pulse therapy on spinal nerve function in patients with acute spinal cord injury
Chinese Journal of Biochemical Pharmaceutics 2017;37(9):114-115,117
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.

Tumor 2010;(2):160-163
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.
6.Practice of teaching reform of nuclear medicine
Chinese Journal of Medical Education Research 2013;(6):640-642
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.

Chinese Journal of General Surgery 1993;0(01):-
Objective To investigate the clinicopathologic features of gastrointestinal stromal tumors(GISTs). MethodsThe diagnosis and treatment results of GISTs were studied, and clinicopathologic features and immunohistochemical expressions of CD34, smooth muscle actin (SMA) and S-100 protein were detected in 26 cases of GISTs. ResultsThe tumor was found in the stomach(54%), small intestine(38%) and rectum(8%), and malignant tumors accounted for 77% of the cases. The size of tumors was correlated with the malignancy of GISTs significantly(P0.05). ConclusionsTumor size is a predictor of the malignancy of GISTs, and the immunophenotype is not a predictor.
