Objective To examine the localization of neuronal specific transcription factor DAT1 mRNA in the central nervous system of the rat. Methods In situ hybridization histochemistry staining method with digoxigen-labeled cRNA probe was used. Results The Transcripts of DAT1 mRNA were localized in somatic and dendritic profiles at most regions of adult rat central nervous system. It can be observed in cerebrum, cerebellum, thalamus, brain stem and spine. The intense hybridization signal can be seen in olfactory bulb, entorhinal cortex, prepirform cortex, striate cortex, hippocampus CA1 and dentate gyrus, lateral dorsal nucleus of thalamus, red nucleus, dorsal tegmental nucleus, central reticular nucleus of medulla oblongata,motor nucleus of trigemina, nucleus of hypoglossal, vagus nerve nucleus, external cuneate nucleus and ambiguous nucleus. The moderate staining was detected in Ⅱ-Ⅵ layer of cerebrum, hippocampus CA2 and CA3, amygdala nucleus, globus pallidus, medial geniculate body, lateral geniculate body, zona incerta, supraoptic nucleus,paraventricular nucleus, arcuate nucleus, substantia nigra, mesencephalon reticular nucleus, reticular nuclei of pons, gigantocellular reticular nucleus, lateral reticular nucleus, medial nucleus of the trapezoid body, vestibular nucleus, dorsal cochlear nucleus, locus ceruleus, cuneate nucleus, nucleus raphes dorsalis. The faint signal showed in septal nuclei, ventral lateral nucleus of thalamus, ventral posterior nucleus of thalamus, posterolateral nucleus of thalamus, dorsomedial nucleus of thalamus, anterodorsal nucleus of thalamus, premammillary nucleus, central gray, superficial gray layer of the superior colliculeus, central nucleus of the inferior colliculeus, lateral nucleus of the inferior colliculeus, trigeminal mesencephalic nucleus, spinal nucleus of trigeminal, nucleus of solitary tract, inferior olivary nucleus, superior central nucleus, cerebellar fastigial nucleus, interposed cerebellared nucleus, lateral cerebellellar nucleus and spinal cord gray matter. Conclusion The results demonstrated the widely presence of DAT1 mRNA in adult rat central nervous system ,close related to the dopaminergic nervous system, suggesting a role of regulation for this gene in various functions of rat central nervous system, especially in dopamine neurotransmitter regulation.

Objective To probe the application of superimposed flaps in hand surgery. Methods Form March 1998 to December 2003, we repaired 35 cases of skin defects with non trunk blood flaps and neurocutaneous vascular flaps. The area of flaps ranged from 1cm?1cm to 6cm?8cm. Results After operation, the flaps in 33 cases survived, but died in 2 cases due to unsuitable design. The follow ups ranging from 6 to 12 months showed that the quality and color of the survived flaps were similar to those of the normal tissue around. No swelling was found. Conclusion The superimposed flaps have reliable blood supply so that they are an ideal means to repair skin defects of hand.

AIM: To investigate the change of corrected vision and stereo vision in anisometropic patients after laser in situ keratomileusis (LASIK).METHODS: The clinical data of 84 cases of anisometropic children(84 eyes) were retrospective analyzed.The changes of corrected visual acuity and stereopsis of different gender,age,type of amblyopia in children anisometropic before treatment,after treatment for 3,6mo and 1a were analyzed.The stereoscopic vision correction correlation were analyzed.RESULTS: Corrected Log MAR visual acuity and stereopsis of 84 patients after LASIK surgery treatment for 3mo,and 1a later significantly decreased than before treatment (P<0.05).The corrected Log MAR visual acuity and stereopsis of male and female after treatment for 3,6mo and 1a was not statistically significant (P>0.05).Corrected visual acuity of age <30 group for 3,6mo and 1a was significantly lower than the age ≥30 group (P<0.05).After 3,6mo and 1a stereo vision with hyperopic anisometropia amblyopia decreased more than that with myopic anisometropia amblyopia(P<0.05),but corrected Log MAR visual acuity after treatment was no statistically significant difference (P>0.05).Improved correctted vision of anisometropic patients after LASIK surgery had no connection with the decrease of stereo vision(P>0.05).CONCLUSION: LASIK surgery can improve visual acuity in patients with anisometropia amblyopia,but the course of treatment of visual acuity and stereopsis affected by age and type of amblyopia.

Objective To evaluate the etiologies of children with gastrointestinal bleeding(GIB), and the relationship between the pathological findings and clinical.Methods Gastroscopy or proctoscope was performed in 153 children with GIB. Pathological studies and tests as for helicobactor pylori (Hp) were undertaken.Results Among 153 children,140 cases(91.5 %) had definite diagnosis,including 74 children with upper gastrointestinal bleeding(UGIB) and 66 cases with lower gastrointestinal bleeding(LGIB). Gastric pathologic study was conducted in 56 cases. All patients had chronic superficial gastritis(CSFG). Hp test was positive in 33 patients. There was significant difference in the positive rate of Hp test between patients with gastritis or duodenitis and those with ulcers (P

Objective:To analyze and discuss the influence of medical ethics on the quality of life and treatment compliance for breast cancer patients in clinical application, and to expound the positivehidden value of medical ethics to dealing with the doctor-patient relationship. Methods:176 cases of breast cancer patients in a hospital from December, 2012 to December, 2014 were selected to participate in this study. They were divided into experi-mental group (n=88) and control group (n=88) using the sequence number. The subjects in control group were treated according to the NCCN guidelines for breast cancer, while the experimental group was treated with medical ethics on the basis of the routine methods. The effect and safety were explored. Result:In evaluation of the quality of life, it was found that the excellent rate of patients in the experimental group was significantly higher than those in the control group (89. 8% vs. 68. 2%, P<0. 05). The incidence of complications in the study group was sig-nificantly lower than the control group ( P<0 . 05 ) . The complication incidence in the experimental group was sig-nificantly lower than that of the control group (73. 9% vs. 96. 6%,P<0. 05). Conclusion:Medical ethics has a great influence on the quality of life and treatment compliance for breast cancer patients, and its application has a positive indirect and clinical utility.

BACKGROUND: Acute pulmonary embolism (APE) is a disorder involving the pulmonary circulation resulting from a blockage of the pulmonary artery. The present study aimed to investigate the effects of aspirin on the nuclear factor-κB (NF-κB) activity in a rat model of APE. METHODS: A total of 108 healthy male Sprague-Dawley rats were randomly assigned into six groups (n=18 rats per group): control group, sham operation group, APE model group, and low-, medium- and high-dose aspirin groups. Six, 24, and 72 hours after the induction of APE, rats in the low-, medium- and high-dose aspirin groups were given aspirin at a respective daily dose of 150, 300, and 600 mg/kg by gavage for three consecutive days. Rats in the other groups were treated with equal volumes of normal saline. Six rats in each group were anesthetized with 10％ chloral hydrate solution at each time point, and then the lung tissues were colected and analyzed using immunohistochemical staining. RESULTS: Positive immunohistochemical staining was present in the bronchial epithelial cells, alveolar cells, macrophages, and surrounding bronchial smooth muscle cells. When compared with the APE model group, the number of positive cells was significantly lower in the other groups at each time point (P<0.001). Statistically significant differences were also observed among the aspirin-treated groups at 6 hours (P<0.05,P<0.001). Compared with the APE model group, NF-κB protein expression was reduced in the other groups at each time point (P<0.05,P<0.001). Rats from the APE model group had thrombosis, damaged alveolar walls, and pulmonary hemorrhage, along with different degrees of infl ammatory cellular infiltration at each time point. However, pathological changes such as pulmonary hemorrhage and infiltration of inflammatory cells were attenuated after the aspirin treatment. CONCLUSION: Aspirin can significantly inhibit NF-κB activity in the lung of rats with APE in a dose-dependent manner, and can alleviate lung injury after APE.
