Objective To evaluate the efficacy of Mahuang-Fuzi-Xixin decoction and Wuling powder combined with routine western medicine therapy for chronic kidney disease (CKD) stage 3.Methods A total of 65 patients with CKD stage 3 were recruited and randomized into a treatment group (32 cases) and a control group (33 cases).On the basis of the same routine western medicine therapy,the patients in the treatment group was treated with Mahuang-Fuzi-Xixin decoction and Wuling powder,while those in the control group was treated with ketosteril.All patients were treated for one month.Renal function was evaluated by serum creatinine,urea nitrogen and uric acid before and after treatment.The therapeutic effect was compared between the two group.Results The serum ereatinine after treatment in the treatment group was significantly decreased than that in the control group (387.52 ± 92.13 mol/L vs.502.78 ± 117.35 mol/L;t=4.395,P＜0.01).The total effective rate in the treatment group was significantly higher than that in the control group (87.5％ vs.42.4％;X2=12.533,P＜0.01).In respects of syndrome improvements,tiredness/weakness (90.6％ vs.48.5％,x2=11.637),waist soreness/leg weakness (90.0％ vs.35.5％;x2=17.040,P＜0.01),anorexia and tympanites (93.3％ vs.37.9％;x2=17.802,P＜0.01),loose stool (93.1％ vs.25.8％;x2=25.219,P＜0.01),anasarca (84.6％ vs.41.7％;x2=8.214,P＜0.01),pale and teeth-printed tongue (76.7％ vs.26.7％;x2=13.081,P＜0.01) in the treatment group were significantly better than those in the control group.Conclusions Mahuang-Fuzi-Xixin decoction and Wuling powder combined with routine western medicine therapy can improve the renal function and syndromes in patients with CKD stage 3.

Objective To establish a method for determination of trace lead in drinking water by intermittent flow HG-AFS was developed. Methods The conditions for K3Fe(CN)6-KBH4-HCl system of generation of PbH4 were optimized and interference of coexisting ions were tested. Results The fluorescence signal of blank solution was decreased evidently by treating K3Fe(CN)6 with activated carbon and the detection limit was effectively improved. The interference of coexisting ions could be suppressed in some degrees in the presence of K3[Fe(CN)6]. Under the optimized conditions, the detection limit of this method was 0.10 ?g/L and RSD(n=6) was in the rang 0.4%-3.8%. The recovery rate was 95.0%-112.0%. Conclusion This method was accurate, simple, sensitive and suitable for determination of trace lead in drinking water.

Glaucoma is a group of irreversible blind eye diseases with specific optic nerve damage and visual field defect. Early diagnosis and treatment of glaucoma is vital for prognosis, but difficult in clinical practice. Macular ganglion cell complex thickness(mGCC) consists of the inner three layers of retina:retinal nerve fiber, ganglion cell and inner plexiform layers, which is glaucoma target tissue so to be measured the thickness of the mGCC as better indicator for early diagnosis in glaucoma. Optical coherence tomography ( OCT ) is a non-contact, good repeatability technique to obtain fast high- resolution images from the anterior and posterior segments of the eye, and it has been widely used in ophthalmology. Spectral- domain ( SD ) OCT allows a higher image resolution and can measure the thickness of mGCC thickness, providing new parameters for the early diagnosis of glaucoma.

In order to explore the effect of flipped classroom in theoretical teaching of biochemistry,lipids metabolism was selected to carry out four stages flipped classroom.The teaching effect of flipped classroom was evaluated by test and questionnaire survey of students.The results indicated that most undergraduate students could accept novel teaching method.However,the consciousness and the ability of students' independent learning need to be further improved.It also takes time for the students to adapt to the transition from traditional teaching to flipped c1assroom.In summary,the specificity of Biochemistry may limit the carrying out of flipped classroom to some extent.Therefore,which kind of teaching method is adopted depends on the biochemistry theoretical content.Our work may provide some references for further application of flipped classroom in biochemistry teaching.

Objective To study the subchronic toxicity of fipronil in rats and to protect and improve the environment and human health. Methods 80 SD rats were randomly divided into four groups,20 in each groups (10 males and 10 females). The rats were treated with fipronil by gavage,in doses of 25,10,4,0 mg/kg,once a day,10 ml/(kg?d),for 90 consecutive days. The test method was according to GB15670—1995. Results The acute toxicity symptom of rats in high dose showed that cachexia,dull,hair floppy. No acute toxicity symptoms were found in the moderate and low dose groups. No significant difference was found in the serum and urine routine test indexes. Liver index increased significantly in the high dose(25 mg/kg)and moderate dose(10 mg/kg) exposed rats. The activity of aspartateaminotransferase (AST) in the serum increased only in male rats. No significant changes in indicators were found in the low exposed rats. The histopathologic examination showed that in the high and moderate dose groups,in the liver,spot and focus necrosis,the hepatocytes around central veins became bigger and cloudy swelling,some hepatocytes presented ballooning degeneration. No obvious pathological change was seen in the low dose group. Conclusion Fipronil has a toxicity to the liver,based on 90 day oral toxic test in rats,no-observed adverse effect level (NOAEL) is 4 mg/(kg?d).
