1.The therapeutic effect and the prognosis factor prediction of tonsillectomy in IgA nephropathy
Chinese Journal of Postgraduates of Medicine 2008;31(21):28-30
Objective To determine the therapeutic effect of IgA nephropathy treated with tonsillectomy, and investigate the indication and contraindication. Methods Thirty-five IgA nephropathy patients, who were diagnosed by renal biopsy treated with tonsillectomy, were in operation group. Twenty-four hours urine protein, one hour urine erythrocyte and serum creatine were detected before the operation, one week, two weeks, four weeks, six months after the operation. Compared with 40 IgA nephropathy patients, who were treated with medicine (control group). Results The effective power in operation group was 71.4% and in control group was 52.5%. There was significant difference between two groups. Conclusion Tonsillectomy is more effective in IgA nephropathy with chronic tonsillitis, especially when renal corpuscle is slightly impaired, conversely, when renal function is severely damaged, it belongs to surgical contraindication.
2.Relationship between allergic rhinitis and Chinese medical constitution
China Journal of Traditional Chinese Medicine and Pharmacy 2005;0(02):-
Allergic rhinitis is familiar in clinic,in recent years the incidence has the trend of increase annually and the modern medicine has no effective cure at present.How to seek a permanent solution to the problem? Chinese medical constitution has influence on the incidence,syndrome differentiation,treatment and prognosis of allergic rhinitis.It is necessary and possible to prevent it according to Chinese medical constitution.The constitution is the internal and crucial factor of allergic reaction.The external etiologic factors work through the internal etiologic factors,making people get ill through the imbalance of yin-yang.Therefore,treating allergic rhinitis on the basis of Chinese medical constitution has a positive effect on prevention,correct diagnosis and treatment,controlling the progress and improving the prognosis.
3.Recent advance in vitreous substitutes
Chinese Journal of Experimental Ophthalmology 2016;34(4):380-384
In complicated vitreoretinal surgery,vitreous substitutes play a major role in maintaining intraocular pressure.Air,expansion gases,perfluorocarbons liquid,and silicone oil are frequently used in modern vitreoretinal surgery.Long-term vitreous substitute has been attempted with collagen,hyaluronic acid,natural hydrogel polymers and so on.However,an ideal vitreous substitute is being requested for a long time.This review focused on the currently available vitreous substitutes,as well as those in the experimental phase.These compounds were classified based on their functionality,composition,and properties.The clinical use,advantages,and shortcomings of the various substitutes were discussed.Finally,the criteria for an ideal vitreous substitute was defined.

5.Oxidative stress and vascular endothelial growth factor in rats with type 1 diabetes mellitus
Journal of Medical Postgraduates 2015;(6):590-593
O bjective Different degrees of oxidative stress may exist in patients with diabetes mellitus (DM).The aim of this study was to explore the roles of oxidative stress and the level of vascular endothelial growth factor ( VEGF) in the development and progression of DM in the rat model of type 1 DM (T1DM). Methods We established the T1DM model in 23 male SD rats and in-cluded another 17 in the control group .We determined the total anti-oxidation capacity ( T-AOC) and the levels of super-oxide dis-mutase (SOD), glutathione (GSH), and malondialdehyde (MDA) by chromatometry, and measured that of VEGF by ELISA. Results At 7 weeks after modeling, the level of fasting blood glucose(FBG) was significantly increased in the T1DM rats as com-pared with the controls ([23.01 ±3.62] vs [5.08 ±0.46] mmol/L, P<0.05); the levels of GSH and SOD were markedly lower (18.8 [0.36] vs [3.82 ±1.05] g/L and [192.06 ±34.57] vs [242.37 ±32.79] U/mL, both P<0.05) while those of serum MDA and VEGF remarkably higher in the T1DM than in the control rats ([4.94 ±0.63] vs [4.42 ±0.37] nmolm/L and [23.97 ±1.84] vs [22.32 ±1.71] pg/mL, both P<0.05);no statistically significant differences were found in T -AOC between the two groups (P>0.05).FBG was correlated positively with MDA (r=0.51) and VEGF (r=0.47) but negatively with GSH (r=-0.71) and SOD (r=-0.40), while serum VEGF positively with MDA (r=0.32) and negatively with GSH ( r=-0.34 ) in the experimental rats . Conclusion Peroxidation is increased and the anti-oxidation mecha-nism weakened during the development and progression of T 1DM, which is closely related to hyperglycemia .High VEGF is associated with hyperglycemia and enhanced peroxidation .
6.Construction and eukaryotic expression of a recombinant plasmid encoding Pseudomonas aeruginosa toxA and typeⅢsecretion system pcrV
Journal of Medical Postgraduates 2014;(7):694-697
Objective Exotoxin A ( encoded by gene toxA ) , one of the most toxic protein secreted by pseudomonas aerugi-nosa(P.a.), and PcrV (encoded by gene pcrV), key component to type Ⅲsecretion system of P.a., both matter significantly to the virulence of P.a.The article was to construct a novel DNA vaccine encoding a mutated toxA gene and the pcrV gene of P .a.and i-dentify gene expressions in eukaryotic cells . Methods The genes of toxA and pcrV were amplified by PCR , and the toxA gene was mutated to reduce the toxicity of Exotoxin A .Then gene fragments toxA m and pcrV were inserted into eukaryotic expression plasmid pIRES simultaneously to construct a recombinant DNA vaccine pIRES-toxAm-pcrV.The novel plasmid was transfected into HEK-293 cells by lipofectamine 2000 .The expressions of toxA m and pcrV were detected by Western blot . Results Gel electrophoresis demon-strated the target gene fragments encoding Exotoxin A and PcrV .Western blot exhibited proteins encoded toxA and pcrV expressed by HEK 293 cells. Conclusion The recombinant plasmid pIRES-toxAm-pcrV was successfully constructed .Western blot analysis indi-cated the expressions of toxA m and pcrV in HEK-293 cells.It may be used as a potential candidate of preventive vaccine of Pseudo-monas aeruginosa .
