The afferent connections of the lateral hypothalamic nucleus in the rat werestudied with retrograde horseradish peroxidase(HRP)method using microinjection andmicroelectrophoretic technique.The microinjection syringe needle or microelectrophoretic pipette was insertedvertically into the brain or in inclined direction through the cerebellum.The results were as follows:Following HRP introduced into the lateral hypothalamic nucleus,labeled neuronswere found in the anterior hypothalamic nucleus,the paraventricular nucleus,thedorsal raphe nucleus,the locus coeruleus and substantia grisea periventricularis inall cases.In most cases,labeled cells were also observed within the lateral septal nucleus,the interstitial nucleus of stria terminalis,the medial preoptic nucleus,the lateralpreoptic nucleus,the supraoptic nucleus,the ventromedial hypothalamic nucleus,themedial and central amygdaloid nuclei,the nucleus reunius,the interpeduncular nuc-leus,the nucleus parabrachialis dorsalis,the nucleus parabrachialis ventralis,and thenucleus tractus solitanii.In a few cases,retrograde labeling of neurons was observed within the medialseptal nucleus,pars medialis of the nucleus medialis thalami,the supramammilarynucleus and nucleus raphe medianus.In certain cases,a small number of cells could be found in the dorsal tegmentalnucleus of Gudden and the nucleus dorsalis nervi vagi.Among those nuclei,the locus coeruleus,the supraoptic nucleus,the paraventri-cular nucleus and the dorsal parabrachial nucleus were labeled bilaterally.

Objective: To observe the efficacy of needling the Xi-Cleft points of yang meridians plus topical surrounding needling and pregabalin in treating postherpetic neuralgia (PHN) affecting the head and face and its influence on quality of life (QOL). Methods: Eighty patients with PHN affecting the head and face were randomized into an acupuncture-medication group and a Western medication group by their visiting sequence, with 40 cases in each group. The Western medication group took pregabalin capsules orally, 75 mg each time, twice a day. The dosage could increase to 150 mg each time and twice a day within 1 week based on the efficacy and tolerance. The treatment lasted for 5 weeks. The acupuncture-medication group was given additional surrounding needling at the herpes zoster on the head and face, and Xi-Cleft points of yang meridians were chosen according to the affected area for acupuncture, once every other day, for 5 weeks in total. Results: Prior to treatment, there were no significant differences in the visual analog scale (VAS) and QOL scores between the two groups (both P>0.05). After treatment, VAS and QOL scores dropped significantly in both groups (all P<0.01), and were significantly lower in the acupuncture-medication group than in the Western medication group (both P<0.01). The total effective rate was 67.5％ in the Western medication group, versus 92.5％ in the acupuncture-medication group, and the between-group difference was statistically significant (P<0.05). Conclusion: Based on oral administration of pregabalin, needling the Xi-Cleft points of yang meridians and topical surrounding needling can reduce PHN, notably improve patients' QOL, and produce more significant efficacy than oral administration of pregabalin alone.

Background Retinopathy of prematurity is mainly due to retinal neovascularization.Objective This laboratory work was to evaluate the efficacy of different dosage of avastin for inhibiting retinal neovascularization.Methods Ninety 7-day-old clean C57BL/J6 mice were randomized into six groups as follows:air control group,hyperxia control group,hyperxia BSS group and avastin groups.C57BL/J6 mice in air control group were raised in regular air environments.The fifty mice were fed under the environment with 75％ ±2％ oxygen for 5 days to establish the retinal neovascularization models.The 1.25,2.50 and 5.00 g/L avastin (0.5 μl) were injected inteavtreally in forty-five mice models as low,moderate and high dosage avastin groups respectively,and 0.5 μl BSS was used at the same way in fifteen models as hyperxia BSS group.The mice were sacrificed in the 17-day-old age using excessive anesthesia method and the retina sections were prepared for the calculation of the numbers of vascular endothelial cell nuclei broken retinal inner membrane after hemotoxylin and eosin staining.The expression of CD34 in the retina was detected by immunochemistry.The morphology and distribution of retinal neovascular vessel in various groups were observed using retinal flat.The use of the animals followed the Regulations for the Administration of Affairs Concerning Experimental Animals by State Science and Technology Commission.Results The numbers of cell nuclei broken the inner limiting membrane was significant increased in the hyperxia group compared with the air control group( P＜0.01 ),and those in difference doses of avastin were considerably reduced in comparison with hyperxia BSS group (P＜0.01) and hyperxia group (P＜0.01 ).The decrease of numbers of cell nuclei broken the inner limiting membrane was obvious in low dose of high dose of avastin compared with low dose of avastin (P＜0.05 ).CD34 was positively expressed in retina internal membrane of hyperxia group.Retinal flat revealed the regular distribution and normal structure of retinal vessels in air control group and avastin groups.However,retinal and vitreous cavity neovascularization,leakage and enlarged non-perfusion regions in the perimeter of the retina were seen in hyperxia group and hyperxia BSS group. Conclusions Intravitreal injection of avastin can arrest retinal angiogenesis in oxygen-induced retinal neovascularization models in a dose-dependent manner.
