Objective To observe the serum lipid level of patients with branch retinal vein occlusion (BRVO).Methods A total of 71 BRVO patients (BRVO group) were enrolled in this study.The patients included 31 males and 40 females,with an average age of (52.75 ± 10.2) years.All the patients were examined for visual acuity,slit lamp ophthalmoscopy combine with preset lens,fundus color photography and fundus fluorescein angiography (FFA) examination.Seventy-two age-and sex-matched normal subjects were enrolled in this study as control group.The subjects included 32 males and 40 females,with an average age of (53.10±9.5) years.The BRVO and control group were divided into four subgroup which including age with ＜40 years,40-49 years,50-59 years and ≥60 years.The plasma cholesterol and triglyceride level of BRVO group,control group,and age subgroups of BRVO and control group were comparatively analyzed.Results The average plasma cholesterol levels were (4.529±0.100) and (4.274±0.106) mmol/L in BRVO and control group,respectively.There was no difference between two groups (t=-1.738,P＞0.05).The average triglyceride levels were (1.500±0.129) and (1.319±0.095) mmol/L in BRVO and control group,respectively.There was no difference between two groups (t=-1.135,P＞0.05).There was no difference of average plasma cholesterol (t=-1.755,1.850,-1.892,-0.507) and triglyceride (t=0.846,-0.074,-1.288,-1.887) level in age subgroups of BRVO and control subgroup (P＞0.05).Conclusion There is no significant difference of serum lipid level between BRVO patients and controls.

Objective:To investigate serum level of vascular endothelial growth factor(VEGF)in patients with rheumatoid arthritis(RA).Methods:VEGF ELISA Quantikine kit.The serum RF level was also d etermined using Beckman Array 360.Results:The serum concen tration of VEGF was significantly higher in patients with RA than in healthy co ntrol(P＜0.01).Conclusion:It suggests that VEGF is involved in the pathog enesis of RA and that measurment of serum concentration of VEGF is noninvasive, usful method for monitoring the disease activity of RA.

To discuss the availability of evaluation on the dissolution studies of the multicomponents in traditional Chinese medicine, the in vitro dissolution of total composition of the tablet of rhizomes of Ligusticum chuanxiong components and its correlation with the in vivo were studied by the method of area under the absorbance-wavelength curve (AUAWC). Taken the tablet of rhizomes of Ligusticum chuanxiong components which is composed of sodium ferulate and ligustrazine hydrochloride as subject model, the dissolution tests were carried out with basket method. The plasma concentrations of tablets in different rats were determined by AUAWC at different interval times. The in vivo absorption percentage was calculated by Wagner-Nelson equation to evaluate the in vitro and in vivo correlation. According to the results, the cumulative dissolution in vitro of total composition of tablets of rhizomes of Ligusticum chuanxiong components at 60 min was 90.65% in water by AUAWC. The in vivo pharmacokinetics is fitted with an one-compartment model. The linear equation based on the cumulative dissolution rate (fr) and absorption percentage (fa) at 5, 10, 20, 30 and 60 min was fa = 0.819 7 fr+0.183 and the correlation coefficient was 0.959 5, which showed a good correlation between the in vitro dissolution and the in vivo absorption percentage. The method of AUAWC can be used accurately, feasibly and conveniently to evaluate the in vitro and in vivo correlation of total composition of tablets of rhizomes of Ligusticum chuanxiong components, which will provide better guidance to study the in vitro and in vivo correlation of sustained release preparation etc under complex system of traditional Chinese medicine in the future.

In order to increase the yield and quality of the medicinal plant and enhance the competitive power of industry of medicinal plant in our country, this paper analyzed the status, problem and countermeasure of the tissue culture of medicinal plant on large scale. Although the biotechnology is one of the most efficient and promising means in production of medicinal plant, it still has problems such as stability of the material, safety of the transgenic medicinal plant and optimization of cultured condition. Establishing perfect evaluation system according to the characteristic of the medicinal plant is the key measures to assure the sustainable development of the tissue culture of medicinal plant on large scale.

Objective To explore the value of ocular fundus artery hemodynamics in diabetes by the correlation study between ocular fundus artery and glycosylated hemoglobin(GHb).Methods GHb was checked in 98 patients (196 eyes) in diabetes,including 49 cases (98 eyes) before treatment and 49 cases (98 eyes) after treatment,and normal group of 100 cases (200 eyes)An all cases,color Doppler ultrasonography was used for monitorind ophthalmic artery(OA),central retinal artery(CRA) and posterior ciliary artery (PCA).Finally,the differences of the parameters vauels of the the OA,CRA,and PCA between diabetic and normal group were studied in order to find out the relationship with GHb.Results Of 98 patients in diabetes,peak systolic velocity and end diastolic velocity of fundus artery decreased,resistance index increased(RI).There was significant difference between diabetic and normal group(P ＜0.05),and a significant difference was exited between diabetic group before and after treatment(P ＜0.05).GHb were negatively correlated with the velocity of fundus artery,and positively correlated with RI.Conclusions Evaluation of ocular fundus artery hemodynamics in diabetes can provide useful information for diabetic retinal perfusion and function change.For evaluation of diabetic retinal disease,it is of great value in clinical application.

Objective To detect serum galectin 3 levels in patients with chronic kidney disease (CKD) and explore its clinical significance .Methods The galectin 3 levels the serum of in 38 CKD patients and 34 healthy controls were determined by ELISA . All kidney function was measured by automatic biochemical analyzer .The relation between serum galectin 3 levels and the level of kidney function was analyzed by use of t test .Results The serum galectin 3 levels in CKD and healthy controls groups were (1 .22 ± 1 .01)ng/mL and (3 .03 ± 2 .06)ng/mL ,P<0 .05 .There was close negative correlation between serum levels of galectin 3 and Cr ,CysC(P<0 .05) .Conclusion Serum galectin 3 of CKD patients reduces significantly and correlates with kidney function . Detecting on s galectin 3 is helpful for chronic kidney disease diagnosis and therapeutic effect evaluation .

A case of mercury-induced Baboon syndrome is reported.A 31-year-old female presented with a 2-3 day history of pruritic symmetric erythematous papules on both axillas,popliteal fossa,buttocks and groins.The patient was exposed to a broken mercury thermometer two days before the onset of the eruption.Patch testing showed that the patient was sensitive to ammoniated mercury,mercury,mercuric chloride and mercurochrome.The mercury levels in serum and full blood reached the up limit of normal value three days after the onset,and gradually decreased over time.The patient was diagnosed with Baboon syn- drome caused by mercury according to the clinical manifestation and results from laboratory studies.
