Based on the associated theory of spleen-kidney deficiency about the traditional Chinese medicine and experimental research to discuss myasthenia gravis treated by integrative medicine.According to the theory of traditional Chinese medicine,the mechanism of myasthenia gravis is Qi deficiency of the spleen-stomach.Experimental studies showed supplementing spleen and kidney can improve ATP,muscle glycogen,fat content,other molecular biology material foundations,skeletal muscle cells under hypoxia and mitochondrial structure of animal models and patients,and therefore treat the deficiency of both spleen and kidney.

Fungal polyketide synthases are responsible for the biosynthesis of secondary metabolites such as pigments, mycotoxins, and they are very important in pharmacology , food science and agriculture. The recent advances in the methods for the isolation and manipulation of multiple classes of polyketide synthase genes from fungi were introduced. It is useful for discovery of novel fungal polyketide synthase gene clusters. These methods can also be useful for revealing the genetic potential of fungi to produce multiple types of bioactive polyketide.

Objective To observe the curative effect of Xianlinggubao capsules combined with mecobalamin tablets,manipulation and cervical traction in treatment of cervicalspondylotic radiculopathy(CSR).Methods Forty-eight cases CSR patients who were treated in Affiliated Hospital of North China University of Science and Technology from February 2013 to May 2015 were randomly divided into treatment group and control group,each group with 24 cases.All patients were treated with manipulation,cervical traction and mecobalamin tablets(0.5 mg,3 times/d),treatment group received Xianlinggubao capsule(1.5 g,2 times/d)for 21 d.Nervous pain was valued with short-form of McGill questionnaire(SF-MPQ),the difference between the two groups before and after treatment was compared with that before treatment,the pain rating index(PRI),the fuzzy pain rating scale(VAS)and the current degree of pain(PPI).Table 20 quantitative analysis of symptoms of cervical spondylosis of nerve root type was applied to assess the comprehensive evaluation of symptoms and signs,the curative effect was calculate(before and after treatment,and the ratio of the integral before treatment)of the omnibus symptoms and signs.The curative ratio and the healing time were calculated.Results The treatment group McGill in PRI,VAS and PPI score difference were significantly higher than the control group((6.16±1.94)points vs(4.87±2.12)points,(5.23±2.22)points vs.(3.63±1.74)points,(2.76±0.87)points vs.(1.26±1.01)points),the differences were statistically significant(P=0.02,0.03,0.04).Table 20 quantitative analysis index of treatment was significant higher than control group(0.72±0.15 vs.0.37±0.07),the differences were statistically significant(t=1.31,P＜0.05).The curative ratio of treatment group was much higher in control group(70.83％(17/24)vs.45.83％(11/24)),the differences were statistically significant(x2=8.15,P=0.02).The treatment group gained shorter healing time((8.31±3.11)d vs.(11.24±4.52)d,t=3.36,P=0.01).Conclusion Assured curative effect was found in Xianlinggubao capsules combined with mecobalamin tablets,manipulation and cervical traction for cervicalspondylotic radiculopathy.

Objective To observe the changes of femur biomechanical properties in fluorosis rats. Methods Fifty Wistar rats of thirty-day old, weighing 90-100 g, were randomly divided according to body mass into fluorosis and control group of 25 each. Fluorosis group drank tap water containing 100 mg/L of fluoride, the control group drank tap water. The rats were observed of dental growing status and killed after feeding 6 months. Their femurs underwent tensile strength, impact, shear, bending experiments. Results The deteetable rate of dental fluorosis was significantly higher in fluorosis group[92%(23/25)] than control group[0(0/25),X2=38.97, P<0.01]. Biomeehanical data in fluorosis group(225.67±11.81,1.94±0.15,76.62±6.10,39.96.3±3.90) were lower than those of the control group(244.70±13.38,2.39±0.19,87.72±7.05,45.75±3.75) in experiments of tensile strength (MPa), impact toughness (J/mm2), shear and bending strength (MPa). The difference was statistically significant(t=3.372,5.879,3.756 and 3383, respectively, P<0.01) between the two groups. Conclusion Fluorides affected bone metabolism in rats, femur biomechanieal properties ehanged in fluorosis rats.

Purple bacteria are extensively used in bacterial photosynthesis research. This review describes the structure of light-harvesting I, light-harvesting II and reaction center of photosynthetic apparatus of pur- ple bacteria and discusses the regulation mechanisms of photosynthesis (PS) gene transcription, with an emphasis laid on the transcriptional regulation of PS gene by PpsR/AppA system.

Objective To evaluate the efficacy of port catheter system(PCS)placement in pulmonary artery via percutaneous subclavicle vein treatment for multiple metastatic tumor in the two lungs and discuss the PCS technique.Methods Fifteen multiple metastatic tumor patients(13 hepatocellular carcinomas,one mandible grand adenocarcinoma,one oral bottom squamous carcinoma)were carried out with pulmonary artery PCS placement by way of percutaneous subclavicle vein.FPA/FPM/GP chemotherapy scheme were introduced every 4～6 weeks.Results The success rate of PCS placement technique was 93.3%(14/15).One case failed.Percutaneous subclavicle veins were performed 14 cases in right side and 1 in left one.Following up 2～43 months,2～7 chemotherapy cycles(mean 5 cycles)were accomplished,and the clinical CR and PR were achieved in 1 and 3 cases respectively with clinical efficacy rate 28.6%(4/14).Major side reaction was late wound healing in 1 case.Conclusion PCS placement in pulmonary artery treatment for multiple metastatic tumor in the two lungs is effective,and mastering operation technique is the key for increasing operation suc- cess rate.

Objective To study the effects of Guhong injection on the expression of vascular endothelial growth factor (VEGF) in the cortex 14 days after cerebral ischemia-reperfusion. Methods 30 male Sprague-Dawley rats were divided into sham group (n=6), ischemia group (n=6), aceglutamide injection group (n=6), Honghua injection group (n=6) and Guhong injection group (n=6). The middle cerebral arteries of all the rats were occluded for 2 hours and reperfusion, except the sham group. Drugs were administered once a day 24 hours after reperfusion. The expression of VEGF in cortex was detected with enzyme-linked immunosorbent assay (ELISA) 14 days after reperfusion. Results The expression of VEGF decreased in the ischemia group compared with the sham group (P<0.001), and it increased both in the aceglutamide and Guhong injection groups compared with the ischemia group (P<0.05). Conclusion Guhong injection can significantly increase the expression of VEGF in the cortex 14 days after ischemia-reperfusion, which may be one of the ways for neuro-protection.
