Latrodectus tredecimguttatus (commonly known as black widow spiders) have toxins not only in their venom glands, but also in other parts of their body, in their eggs and even in the newborn spiderlings. The study on the toxins in venom and materials outside the venom glands of the spiders to elucidate their differences and similarities, evolutional relationship and biological functions is of important theoretical and applicable significance. The development of modern protein chemistry and proteomics techniques has provided efficient means for the study of protein and peptide toxins of L. tredecimguttatus. By using such techniques, the molecular base and action mechanism of the toxins can be revealed at the levels of both single purified proteins and omics. Up to now, although protein chemistry and proteomics study on L. tredecimguttatus toxins have achieved a certain progress, the relevant work particularly that on the toxins in the materials outside the venom glands has to be further deepened.

Potassium channels which are targets of antiarrhythmic drugs (class III) play an important role in cardiomyocyte membrane. Recently, with the application of molecular biology techniques , development of cloned potassium channels, successful isolation of human cardiomyocytes and research of single channel, scientists have learnedmore characteristics of kinetics, electrophysiology and pharmacology of potassium channels. All these help them to develop and study new antiarrhythmic drugs.

Objective To identify the neuroimaging determinants which could predict the occurrence of the vascular dementia (VaD). Methods The findings of cranial MRI were compared in 30 VaD patients and 30 stroke without dementia (SWD) patients by means of quantitative measurement of some indexes. The indexes of measurement included the cerebral white matter lesion (WML) area, the cerebral infarct area, the ratio of ventricle to brain(VBR) and the ratio between the areas of the corpus callosum and supratentorial brain at the midsaggittal plane. Discriminant analysis was used to search for the indexes which could contribute significantly to distinguishing the two groups. Results Small cerebral vessel disease and multi infarct were two major basal diseases of VaD in this series. The WML areas( t =-3.544, P =0.000), the left cortical infarct( Z =-2.538, P =0.011) and VBR ( t =4.475, P =0.000) were significantly higher and the corpus collsum areas( t = -4 616, P =0.000) was significantly lower in the VaD group than that in the SWD group. The indexes that could significantly discriminate the two groups was: callosal atrophy, ventricle to brain ratio, WML area, left cortical infarct area, left parietal infarct area, total cortical infarct area. Conclusions Callosal atrophy, lateral ventricle enlargement and extensive WML are important predictors of incidence of dementia in the small vessel disease; however, left cortical infarct, especially left parietal infarct, is important predictor of incidence of dementia in the multi infarct.

Objective To compare the therapeutic efficacy between conventional nursing and conventional nursing plus electroacupuncture in treating gastrointestinal dysfunction after abdominal operation, and their effects in recovering gastrointestinal function. Method Sixty patients with gastrointestinal dysfunction after abdominal operation were randomized into an electroacupuncture group and a control group according to their operation time, 30 cases in each group. The electroacupuncture group was intervened by conventional postoperative nursing plus electroacupuncture, by selecting bilateral Zusanli (ST36), Shangjuxu (ST37), Xiajuxu (ST39), Neiguan (PC6) and Taichong (LR3), connected to HANS electroacupuncture device, with frequency at 2 Hz and a tolerable intensity. The treatment was given once a day, for 5 d in total, till the recovery of gastrointestinal function. The control group was intervened by conventional postoperative nursing. The therapeutic efficacy was evaluated at the end of the intervention. The time of first bowel sound, first exhaust time, and first bowel movement time were observed. The gastrointestinal symptom score (GIS) was adopted to evaluate the effects of the two methods in improving gastrointestinal function at the end of the intervention. Result The general therapeutic efficacy of electroacupuncture group was better than that of the control group(P<0.05). In the electroacupuncture group, time taken for the first bowel sound, first exhaust and first bowel movement after the operation was shorter(P<0.05). The GIS dropped in both groups after the treatment, and the improvement was more significant in the electroacupuncture group(P<0.05). Conclusion Electroacupuncture helps promote the recovery of gastrointestinal function in patients with postoperative gastrointestinal dysfunction, and can produce a more significant improvement.

Short stature refers to the individual of the same race,gender and age,whose height is lower than the average height for about 2 standard deviations or under the 3rd percentile in the similar living environment.Its etiology mainly includes growth hormone deficiency,hypothyroidism,idiopathic short stature,Turner syndrome and so on.Short stature can be treated in childhood with recombinant human growth hormone (rhGH).Clinical evidence suggests that doctors should pay attention to thyroid hormone levels before and after rhGH therapy,so that they can offer thyroxine timely and maintain normal thyroid function for the children with hypothyroidism,which can improve the efficacy of rhGH in children with short stature.
