To explore the effects of brain derived neurotrophic factor (BDNF) on hypoxic ischemic encephalopathy in neonatal rats,0 2, 0 5 or 2 0?g of BDNF was injected into cerebroventricles of 7d neonatal Sprague Dawley rats with hypoxic ischemic encephalopathy by ligation of left common carotid artery and 2 5h inhalation of humidified 8% O 2 +92% N 2 at 37℃. Its effects on brain edema, levels of malondialehyde (MDA) and neuronal apoptosis at the left cortex and hippocampus were observed. The results showed that brain edema was markedly alleviated in 0 5?g group compared to the vehicle group 24h after BDNF injection. Levels of MDA in the left hemisphere in 2 0?g group were significantly higher than those in either vehicle group or 0 5?g group. Neuronal apoptosis decreased to a different extent in the three groups while obviously in both 0 2?g and 0 5?g groups. It is suggested that BDNF exerts a prominent protective effect on hypoxic ischemic encephalopathy in neonatal rats, but this effect is lowered when overdose is injected.

OBJECTIVETo establish a general method of focal cerebral ischemia model in different varieties of mice.
METHODEach group of healthy adult KM and C57BL/6 mice were randomly divided into control group (n = 10) and MCAO group (n = 10). The mice in MCAO group were applied in the preparation of the MCAO model by intraluminal occlusion using monofilament. Twenty-four hours after operation,the neurologic function was evaluated,middle cerebral artery blood flow was monitored and the infarction volume was calculated by TTC staining, to evaluate the reliability of the model.
RESULTIn the MCAO group, the base value of the cerebral blood flow down of KM and C57BL/6 mice respectively was (81.65 ± 4.59)%, (83.68 ± 6.25)%. The neurological deficit score respectively was (2.30 ± 0.82), (2.50 ± 0.80). TTC staining can clearly show the infarction area, and relatively stable, 24 hours of the survival rate of KM and C57BL/6 mice were 100% and 80% respectively.
CONCLUSIONThe key link is the optimization and improvement of monofilament, temperature, anesthesia and so on. The modified intraluminal occlusion of MCAO using monofilament is a kind of reliable and simple method to establish experimental cerebral ischemia model in mice.

Objective To apply a hand function laserimager to evaluate the effect of acupuncture on hand dysfunction after stroke. Meth-ods From January to June, 2016, 18 stroke patients with upper limb dysfunction were divided into control group (n=9) and acupuncture group (n=9). The control group received routine medication and rehabilitation, while the acupuncture group received acupuncture in addi-tion. They were assessed with modified Ashworth Scale (MAS), Fugl-Meyer Assessment (FMA) of upper limb motor function and modified Bathel Index (MBI) before and after three-week treatment, while the region of interest (ROI) of their hands was tested with the hand func-tion laserimager. Results The scores of MAS and FMA improved after treatment in both groups (t>4.44, P<0.01), and improved in the score of MBI in the acupuncture group (t=3.95, P<0.01). The scores of MAS, FMA, and MBI improved more in the acupuncture group than in the control group (t>3.17, P<0.01). Meanwhile, the scores of ROI decreased in the affected hands after treatment (t>7.78, P<0.001), and de-creased more in the acupuncture group than in the control group (t=-2.23, P<0.05). No significant difference was observed in the scores of ROI of the unaffected hands (t=-0.11, P>0.05) between groups. Conclusion The hand function laserimager, which responds to the blood perfusion of the hand, can be used as a tool to evaluate the hand function.

Objective To evaluate the risk of plague occurrence via surveying and analyzing indoor rat density and flea index in natural villages having previous plague experience. Methods During August to September 2007, 30 natural villages experiencing previous plague were selected based on the surveillance data, and then all households were coded with numbers and 20 households in each village were randomly selected via computer. Cages and sticky papers were set in 600 selected households to capture rats and fleas. Rat density, flea prevalence, flea index and median were estimated. Results One hundred thirty-three Rattus flavipectus and 33 Suncus murinus were caught and averaged rat density was 2.8 rats per one hundred cage. nights (166/6000), the median was 5 rats each village. One hundred and one mice infected fleas, flea prevalence on rats was 60.8% (101/166), 296 Xenopsylla cheopis and 48 Leptopsylla segnis were collected. Rat flea index was 2.1 fleas per rat (344/166). A total of 315 dissociated flea was caught, average dissociated flea index was 0.026 fleas per sticky paper (315/11888). The median was 5.5 dissociated fleas per village. Of dissociated fleas, Ctenocephalides felis felis (205) and Xenopsylla cheopis (103) accounted for 97.8% (308/315). The proportion for species of the rat flea and the dissociated flea was different(Fisher test: P < 0.01). The rat flea was significantly associated with the rat density(r = 0.68, P < 0.01), but the dissociated flea was significantly associated with neither the rat density(r = -yield than fried wheat batter(χ2 = 5.59, P < 0.05). Conclusions In these villages having previous plague experience of Lianghe County, Rattusflavipectus was dominant species of indoor rats, Xenopsylla cheopis and Ctenocephalides felis felis were dominant species of rat flea and dissociated flea, respectively. Mengsong, Bangdu, and Tangjiatun village had potential risk of plague emergence.

Studies on the variation of amylase, lipase and lrotease activity of Whitmania pigra in 0-6 months old using 3, 5-dinitro- salicylic acid colorimetry, right-nitrophenyl palmitate ester (ρ-NPP) colorimetry and folin-phenol method. The results showed that pro- tease activity remained low before 1.5 months old and with the highest activity in 2 months old, but after showing a small peak in 4 months, alkaline protease rapid declined. Amylase was low at born, then gradually increased the activity of the highest in 2.5 months old. Lipase with a strong vitality at birth, then 1 month with minimum and 2 months peaked, but appeared a small peak in 4 months old. In summary, only lipase exhibits strong activity at birth, lipase with the strongest activity in the digestive tract during develop- ment. Protease, lipase and amylase with the strongest activity at 2-3 months old, but were decreased after 4 months old.

Mouthpart developmental histology of Whitmania pigra at different month of age were studied by paraffin section, HE staining combined alcian blue and periodic acid schifts reaction procedure (AB-PAS). The following results was obtained: Change ranges: oral width 0.6 mm (1-3 month), 1.2 mm (34 month); oral diameter 0.3 mm (1-3 month); 1.2 mm (34 month), the oral size reached maximum during 4-6 months and unchanged thereafter. Oral lip had a thin protective film located in the front of the mouthpart. The W. pigra possessed three jaws in oral cavity, the big one was in dorsum, the other two separated on both side of abdomen respectively. Jaws and muscular pharynx were interrelated closely. The jaws were composed by cuticle, epithelial layer, muscularis and jaw cavity from outside to inside. In the front of jaws had mastoid abdomen with function of secreting acidophilic granule from 2 month age. Oral cavity was composed by mucosa, submucosa and muscularis inside and outside. Oral cavity was rich of peristomial nerves. And pharynx was composed of mucosa, muscularis, adventitia from inside to outside. The folds height and width become heighten and thicken. Mucosa epithelium from complex flat epithelium changed into columnar epithelium, muscularis gradually developed into thickened along with growing. Muscular thickness reached maximum at 4 months. Mucous cells of W. pigra were classified into I-IV types based on different staining and two mainly morphological shapes (Tubular, Pear-shaped). Jaws, oral cavity, pharynx by AB-PAS staining showed little changes at different month of age. Mucous cells were few at 1 month age, and type II cells were increased rapidly in 2-3 month age in oral lip. Oral cavity contains more mucous gland cells type I. Under the muscularis there were connective tissues which distributed a few of mucous cells type II.
