Objective To explore the therapeutic mechanism of Huangqin Zhengqi Capsule(HZC)for the syndrome of damp retention in middle-jiao.Methods The rat model of damp retention in middle-jiao was established according to the literature.HZC was administered by gastric gavage in the dosage of 0.175,0.350 and 0.700 g/kg.After treatment,the serum gastrin content,small intestinal absorbency to D-xylose,small intestinal peristalsis,activities of gastric mucosal protective factors such as superoxide dismutase (SOD) and catalase(CAT)as well as gastric pathologic changes were observed.Results HZC can obviously increase serum gastrin content,increase small intestinal absorbency to D-xylose and peristalsis of small intestine,increase the activities of SOD and CAT,as well as improve the gastric pathologic changes in model rats(P

Objective To observe the therapeutic effect of electroacupuncture combined with rehabilitation exercises on swallowing function and cerebral perfusion in dysphagic stroke patients.Methods Sixty-two stroke pa- tients with dysphagia were randomly divided into a treatment group(n=32)and a control group(n=30).The treat- ment group received electroacupunture,rehabilitation exercise and conventional medical treatment,while the control group received only rehabilitation exercise and conventional medical treatment.They were treated once a day,6 times a week for 4 weeks.Water drinking test,stethocatharsis scores and swallowing fluorography were used to assess the swallowing function before and after treatment.Single photon emission computed tomography(SPECT)was also em- ployed to observe the status of cerebral perfusion before and after treatment.Results It was shown that the swallo- wing function and cerebral perfusion in the treatment group were significantly better than the control group after treat- ment.The effective rate in the treatment group was 96.88% while that of the control group was 66.67%.Conclu- sion Electroacupuncture combined with rehabilitation exercises is effective in treating the dysphagic stroke patients, and can significantly improve the brain perfusion of these patients.

ObjectiveTo investigate the effect of filtering surgery on glaucoma.Methods50 glaucoma cases (60 eyes) were underwent trabeculectomy, including paracentesis in advance, suturing of sclera flap and conjunctiva flap, using mitomycin (MMC) and forming anterior chamber as soon as finished operation. All cases were followed up 1 year.ResultsPostoperative IOP was lower than 21 mmHg in 54 eyes, 6 eyes were <30 mmHg when treated with drugs. After operation, there were only 2 eyes had lower vision, the others had higher vision. Two eyes had conjunctiva filtering, two eyes had choroidal separation, but they recovered after non surgical therapy.ConclusionFiltering surgery can decrease common complications, increase vision of early stage, and make IOP recovered to normal.

ObjectiveTo observe the retinal function and nerve fiber layer (RNFL) thickness after laser in situ keratomileusis (LASIK). MethodsLASIK was performed in 15 cases (30 eyes) with myopia after strict preoperative examination. All examinations such as vision, correction vision, diopter, intraocular pressure, corneal thickness, ocular axis, topography scan and fundus of eye examination were performed before and 1 day, 1 week, 1 month,3 months and 6 months after operation, as well as electroretinography (ERG), visual evoked potential (VEP), optical coherece tomography at same time. ResultsThere was not significant difference in the intraocular pressure, ERG and VEP 1 day after LASIK. The thickness of RNFL decreased 1 week after LASIK (P<0.05) and recovered 1～6 months later. ConclusionLASIK does not disturb the retinal function and RNFL thickness irreversiblely.

Objective To investigate the correlation between α1-adrenergic receptor and the pathological behavior of cholangiocarcinoma, and the effects of norepinephrine (NE) on the proliferation of cholangiocarcinoma cell line QBC939. Methods Thirty-six samples of cholangiocarcinoma were resected in Southwest Hospital from August 2002 to March 2008. The expression of α1-adrenergic receptor in the 36 samples of cholangiocarcinoma tissue and 4 samples of normal bile duct tissue were detected by SABC technique. The proliferation of cholangio-carcinoma cell line QBC939 was detected after processing the cells with NE, phentolamine and prazosin. All the data were analyzed by chi-square test. Results The high positive expression rate of α1-adrenergic receptor was 68% (17/25) in patients with lymph node metastasis, which was significantly higher than 9% (1/11) in patients without lymph node metastasis (χ2=10.604, P<0.05). The high positive expression rate of α1-adrenergic receptor was 85% (11/13) in patients with middle and low positioned cholangiocarcinoma, which was significantly higher than 30% (7/23) in patients with hilar cholangiocarcinoma (χ2=9.753, P<0.05). NE promoted the proliferation of cholangiocarcinoma cell line QBC939 by stimulating the expression of α1-adrenergic receptor, and in a concentration-dependent manner. The proliferative effect was weakened as time passed by, and it was eliminated by phentolamine and prazosin. Conclusions The expression of α1-adrenergic receptor is diverse due to lymph node metastasis and the location of the tumor, α1-adrenergic receptor with high expression may play an important role in the proliferation and metastasis of cholangiocarcinoma.

As the main part of the teaching activities,students play an important role in the teaching reform.The students were trained through 3 pathways,“Extending teaching activities from the classroom to the outside”,“Development from basic to clinical knoledge” and “Culturing students' innovative consciousness”,so as to allow them to give full play in teaching reform,to enhance their ability of practice and learning by themselves,to culture their innovative consciousness and to develop students' leading functions in the anatomy teaching reform.

Objective To explore the gene expression of interleukin-13 receptor (IL-13R)?2 and its relationship to proliferation activity of human gliomas.Methods The gene expression of IL-13R?in 50 hu- man gliomas,2 malignant human glioma cell lines and 6 normal brain tissues were studied by RT-PCR.Ki-67 labeling index (Ki267 LI) of all sample were detecteded by immunohistochemical staining.Results Only one normal brain tissues expressed very low IL-13R?2 mRNA,whereas 35 (70%) of 50 human brain tumors expressed 1L-13R?2 mRNA.The positive rate and expression level of IL-13R?2 mRNA were increased with the ascending of WHO tumor grade.(former:rs=0.87;letter:rs=0.69,P＜0.01).The difference of posi- tive rate and expression level of IL-13R 2?mRNA between the low grade and high grade tumors was statistical- ly significant,the proliferation activity of gliomas evaluated by Ki-67LI (Ki-67 Labeling Index,Ki-67LI) was positively correlated with IL-13R?2 gene expression and the tumor grade.Conclusion In human cerebral gliomas,IL-13R?2 genes may play an role in the malignant progression.The expression level of malignancy in molecular level and selecting the target of gene therapy.
