BACKGROUND: During vascular dementia, ischemia, hypoxia, energy expenditure, abnormal metabolism of neurons, decrease of generation of Adenosine Triphosphate and disorder of ionic environment in and out of cells are observed in brain tissue, which can cause abnormal release of monoamine transmitter.OBJECTIVE: To probe into effect of shenma yizhi capsule on content of monoamine transmitter in brain tissue of rat models with vascular dementia induced by multiple cerebral infarction.DESIGN: Randomized controlled study.SETTING: Pathological and Physiological Department o Liaoning Basic Medical Institute.MATERIALS: Totally 96 Wistar rats of either gender,aged 8-12 months, weighing 270-500 g, were selected. METHODS: The experiment was completed in the Pathological and Physiological Department of Vocational-technical College, Liaoning College of Traditional Chinese Medicine from April to July 2001. All rats of either gender were divided into 6 groups with 16 in each group. Wistar rats in 5 groups were injected with cruor embolus in internal carotid artery to make animal model of vascular dementia induced by multiple cerebral infarction.After modeling, rats were randomly divided into 3.2 g/kg, 1.6 g/kg and 0.8 g/kg shenma yizhi capsule groups (shenma yizhi capsule was extracted from ginseng and tall gastrodia tuber with 2.7 g raw materials and provide by Xiyuan Hospital of Chinese Academy of Traditional Chinese Medicine),positive control group and dementia control group. Animals without modeling were regarded as normal control group. Rats in each dosage group were perfused with the corresponding dosage of shenma yizhi capsule; rats in positive control group were perfused with 1 mg/kg hydergine dihydroergotoxine; rats in dementia control group and normal control group were perfused with the same volume of saline solution. One week after modeling, rats were medicated once a day for 6 weeks. Content of monoamine transmitter was measured with high performance liquid chromatograpy.MAIN OUTCOME MEASURES: Content of monoamine transmitter such as levarterenol, adnephrin, dopamine, indoleacetic acid, homovanillic acid and 5-serotonin.RESULTS: Nine rats died because of self-body quality and environmental change, and totally 87 animals entered the final analysis. Content of levarterenol of rats in dementia control group was lower than that in normal control group [(0.40±0.23), (0.70±0.14) ng/g, t=2.712, P ＜ 0.01]; content of levarterenol of rats of 3.2 and 1.6 g/kg dosage groups was higher than that of dementia control group [(0.57±0.09), (0.58±0.19), (0.40±0.23) ng/g,t=2.211, P ＜ 0.05], but was lower than that of normal control group. Content of levarterenol of rats of 0.8 g/kg dosage group was lower than that of normal control group [(0.48±0.23) ng/g, t=2.213, P ＜ 0.05], but was higher than that of dementia control group and positive control group [(0.41 ±0.19) ng/g]. Differences of other neurotransmitters were not significant.CONCLUSION: Content of levarterenol in brain tissue of rats of dementia control group is decreased obviously, but shenma yizhi capsule can increase content of levarterenol in brain tissue of rats. The mechanism of shenma yizhi capsule on treating vascular dementia is possibly related with increasing content of levarterenol in brain tissue.

Objective:To evaluate the role of hemopexin (HPX) in cerebral ischemia-reperfusion (I/R) injury in rats.Methods:One hundred and twenty healthy male Sprague-Dawley rats, aged 7-8 weeks, weighing 250-280 g, were divided into sham operation group (S group, n=36), cerebral I/R group (I/R group, n=36), vehicle group (V group, n=24), and HPX group ( n=24). The model of cerebral I/R injury was established by 120 min middle cerebral artery occlusion followed by reperfusion in anesthetized rats.At 6, 12 and 24 h of reperfusion, 4 rats in S group and I/R group were sacrificed, and the ischemic penumbra of the ipsilateral cerebral cortex was obtained to detect the expression of HPX by Western blot.In I/R, V and HPX groups, 0.9% normal saline 10 μl, 0.1% NaN 3 10 μl, and 1.86 mg/ml HPX 10 μl were injected into the lateral ventricle, respectively, immediately after reperfusion.Eight rats in each group were selected, and neurological deficit was scored at 1-7 days of reperfusion.Eight rats in each group were sacrificed at 1 and 7 days of reperfusion, brains were removed, and brain tissues were obtained for measurement of infarct size, and the percentage of infarct size was calculated. Results:Compared with S group, the expression of HPX in cerebral ischemic penumbra was significantly up-regulated at 24 h of reperfusion in I/R group, and the neurological deficit scores were significantly decreased at 1-7 days of reperfusion, and the percentage of cerebral infarct size was increased at 1 and 7 days of reperfusion in I/R, V and HPX groups ( P<0.05). Compared with I/R group, the neurological deficit scores were significantly increased at 1-7 days of reperfusion, and the percentage of cerebral infarct size was decreased at 1 and 7 days of reperfusion in HPX group ( P<0.05), and no significant change was found in the above indicators in V and I/R groups ( P>0.05). Conclusion:Up-regulation of HPX expression is the endogenous protective mechanism of cerebral I/R injury in rats.

There is a variety of gut microbiota in human body, which is closely associated with the health and disease. Normal gut microbiota can produce colonization resistance to pathogens. Antibiotics can affect the composition of gut microbiota and change the intestinal microenvironment, resulting in intestinal microecological disorders, which in turn cause intestinal pathogenic infections and other diseases. In this paper, the concept of intestinal microecology, the mechanism of intestinal colonization resistance, the effect of antibiotics on intestinal microecology, and the treatment methods were reviewed, aiming to provide the information for the rational use of antibiotics and the development of more effective treatment methods to maintain the stability of intestinal microecology.

Abstract?AIM: To evaluate the visual acuity, visual function, q uality of lfi e, and cost/effectiveness of cataract surgery in patients with low soc ioeconomics tatus ( LSES ) who received government subsidies for free cataract surgery.?METHODS: Retrospectively, 334 eyes of 334 patient s were reviewed. Visual function and quality of l ife questionnaires we re available in 83 patie nts. The cost/effectiveness of cataract surgery was analyzed in 225 patients with LSES and 12 0 patients who rec eived standard cataract surgery. Mutl iple linear regression anal ysis and logistic regression analysis were used to assess the factors affecting the postoperative visual acuity.?RESULTS: At 1wk postoperatively, uncorrected visual acuity ( UCVA ) was improved significantly compared to these preoperait vely (P<0.50 ), 235 eyes (70.4%) had UCVA of 20/40 or better, and 16 eyes (4.8%) had UC VA wor se than 20/400. Multiple linear regresis on ana lysis revealed that other ocular diseases and cataract classification wer e factors contributing to po stop erative UC VA. Logistic regression analysis showed that low preoperative visual ac uti y and other ocular diseases were risk factors of postopera tive low vision, and the odds ratio (95%confidence int erval) values were 6.5 (2.8-14.8) and 1.3 (1.0-1.6), respe ctively.Visual fun ction and quality of life were significantly improved after the surgery. Th e cost/effetc iveness of c ataract su rgery in patients with LSES was lower than that in standard cataract patients.?CONCLUSION: Visual acuity and visual function were significantly better after the surgery in catara ct patients wti h LSES, and the operation cost was low.Quality of life in these patients was significantly improved.

On account of the dense cuticles of the fresh stem and the light, hard and pliable texture of the dried stem, Dendrobii Caulis is difficult to dry or pulverize. So, it is very important to the ancient doctors that Dendrobii Caulis should be properly treated and applied to keep or evoke its medicinal effects. The current textual research results about the preliminary processing, processing and usage methods of Dendrobii Caulis showed that: (1) In history the clinical use of fresh or processed Dendrobii Caulis as teas and tinctures were very common. (2) Its roots and rhizomes would be removed before using. (3) Some ancillary approaches were applied to shorten drying times, such as rinsing with boiling mulberry-ash soup, washing or soaking with liquor, mixing with rice pulp and then basking, etc. (4) According to the ancients knowledge, the sufficient pulverization, by means of slicing, rasping, hitting or pestling techniques, was necessary for Dendrobii Caulis to take its effects. (5) The heat processing methods for Dendrobii Caulis included stir-baking, stir-frying, steaming, decocting and stewing techniques, usually with liquor as an auxiliary material. Among above mentioned, steaming by pretreating with liquor was most commonly used, and this scheme was colorfully drawn in Bu Yi Lei Gong Pao Zhi Bian Lan (Ming Dynasty, 1591 CE) ; moreover, decocting in advance or long-time simmering so as to prepare paste products were recommended in the Qing Dynasty. (6) Some different processing programs involving stir-baking with grit, air-tightly baking with ondol (Kangs), fumigating with sulfur, which appeared in modern times and brought attractive outward appearance of the drug, went against ancients original intentions of ensuring drug efficacy.

Spleen kidney Yang deficiency (SKYD) diarrhea is a common syndrome in tranditional Chinese medicine (TCM). Until now, there is not an ideal SKYD diarrhea rat model for the research. In this study, we compared single factor way (method I, injecting hydrocortisone and gavaging Sennae Folium) with compound factors way(method II, gavaging adenine, improper diet, exhaustion, and gavaging Sennae Folium) on establishing SKYD diarrhea rat model. After modelling, diarrhea index, D-xylose excretory rate, NOS/cGMP signal transduction system, organ index and histopathology examination were used to evaluate the two ways. The results showed that, compared with health group, all the assessment criterias of method I and method II had significant differences (P < 0.01, 0.05). In addition, the index such as diarrhea index, NOS/cGMP signal transduction system, organ index (kidney, testis and thymus) and histopathology examination had significant differences (P < 0.01, 0.05) between method I and method II. In conclusion, the compound factors modelling method better conforms to the symptom of diarrhoea model caused by SKYD. This new modelling method provides a basis for studying on TCM astringents warming and tonifying the spleen and kidney, relieving diarrhea.

Methods Basing on the data obtained from death surveillance system of Xiaoshan from 2002 to 2007, ICD-10 was used to classify death causes. The mortality and proportion of death causes of traffic accident were calculated. Results The mortality of traffic accident was 26.28/100, 000, which ranked the first among all death causes of injury. The mortality in male was significantly higher than that in female, and increased with age. Death resulted from the vehicle-man collision was on the top among the 9 kinds of deaths due to traffic accidents, and 46.43% of death were the people over 60 years old. Motorcycle accident incidence was common in the age of 20 to 59 years old, accounting for 91.80% of motorcycle deaths, in which male was the major victims, accounting for 87.12%. Conclusion Traffic accidents have become an important public health issue in Xiaoshan District. Social departments should actively take measures to strengthen the propaganda and education of road traffic laws and regulatiens to reduce traffic accidents and deaths.

OBJECTIVETo observe therapeutic effects of locking titanium plate for the treatment of comminuted proximal humeral fracture in elderly.

METHODSFrom June 2011 to May 2013, 72 elderly patients with comminuted proximal humeral- fractures were divided into locking titanium plate group and anatomical plate group, 36 cases in each group. In locking titanium plate group, there were 16 males and 20 females aged from 60 to 79 years old with an average of (69.55±5.62) years old; 10 cases were type Neer II, 18 were type Neer III and 8 cases were type Neer IV in accordance with Neer classification; treated with locking titanium plate. In anatomical plate group, there were 15 males and 21 females aged from 60 to 81 years old with an average of (69.76±5.70) years old; 9 cases were type Neer II, 20 were type Neer III and 7 cases were type Neer IV; and treated with anatomical plate. Clinical effects, preoperative and postoperative Neer scoring, operative time, bone healing time and incidence of complications between two groups were compared.

RESULTSAll patients were followed up from 1 to 3 years with an average of 15 months. The excellent and good rate of locking titanium plate group (91.7%) was significantly higher than anatomical plate group (75.0%). Postoperative Neer score of two groups were improved obviously, but locking titanium plate group (92.51±7.85) was higher than anatomical plate group (83.64±8.56); there was no significant differences between two groups in operative time (P>0.05); bone healing time in locking titanium plate was (18.6±3.4) weeks, and shorter than anatomical plate group (24.3±3.9) weeks; incidence of complications in locking titanium plate was (5.6%) shorter than anatomical plate group (22.2%), and had obviously differences between two groups.

CONCLUSIONLocking titanium plate for the treatment of comminuted proximal humeral fracture in elderly plays an important role in good rate, bone healing time and Neer score. It has advantages of early rehabilitation exercise, less shoulder pain, rapid recovery of shoulder joint, less complications, safe and effective, and be worthy of clinical application, especially for senile osteoporosis patients.
