Objective To investigate the effect of implanting uncovered self-expandable metal stent for treatment of distal malignant biliary obstruction through endoscope.Methods The effect of therapy about implanting uncovered self-expandable metal stents to 16 patients who had unsectable malignant tumors companing with obstructive jaundice through endoscope was reviewed. Results Fifteen of the studied patients were implanted uncovered self-expandable metal stents successfully (94%), for their internal drainage were patent. At the seventh and fourteenth day after implantation, liver function and B-ultrasound were rechecked. Compared to the data before operation, total bilirubin, direct bilirubin and transaminase declined respectively (P

Objective: To study the mechanism of Gengnianle Water-paste Pills in resisting climacteric aging. Methods: Rats were randomly divided into blank group, model group, high and low dosage groups of Gengnianle, positive control group. The climacteric rat model were established by ectomizing the bilateral ovaries. The E2, follicle-stimulating hormone (FSH), luteinizing hormone (LH), triiodothyronine (T3), thyroid hormone (T4), thyroid-stimulating hormone (TSH) were detected. Results: Compared with model group, in high dose of Gengnianle group, the levels of E2, T3, T4 increased and the levels of FSH, LH, TSH reduced. The effect of high dose of Gengnianle in improving the adjustment function of the thalamus-hypophysis-ovary axis and the thalamus- hypophysis-thyroid gland axis is better than that of positive control group (P

AIM: To investigate the effects of prenatal stress (PS) on neurons and neuronal ultrastructure of hippocampus in offspring rats, and to explore the role of the overproduction of oxidants. METHODS: One month male offspring rats were obtained to observe the neuronal number, neuronal ultrastructure and the number of nNOS -positive cell in hippocampus. RESULTS: The neuronal number of CA1 and CA4 subregions in late gestation stress (LS) offspring decreases significantly. The neuronal ultrastructure of CA1 subregion in MS (stress in 7-13 days of gestation) and LS offspring appeared bulgy mitochondria, unclear membrane and irregular electron density. Lipofuscin pigments increased; The number of nNOS-positive cell in CA1, CA2, CA3 subregions and DG of MS group and the whole hippocampus of LS group increased significantly. CONCLUSION: PS damaged the neurons and neuronal ultrastructure of hippocampus of offspring rats. The damages were associated with the overproduction of oxidants.

The distributioa of Se in Hb and the effects of Se intake and its chemical forms oil the distribution were studied. The results showed that Se in human Hb was all located in globin and divided equally in a and ? chains. However, a part of Se could fall from Hb during the process of isolation when more Se as SeMet was taken and "excess" Se appeared in Hb. It was implicated that there were at least two kinds of linkage between Se and Hb --tight and loose.Regarding the components of amino acid in ? and ? chains, we assumed that a tight linkage between Se and Hb was in the form of SeMet, which was incorporated into Hb by dietary Se during the synthesis of Hb; the loose linkage was formed by a part of "excess" Se and CyS, especially No.93 CyS in ? chain, being unstable sclcnotrisulf ide or selenopersulfide, which broke easily by reduction during isolation. They might be utilized first by human body when Se was required.

Objective To discuss how to use the core elements of international classification of functioning,disability and health(ICF) as a guide in stroke operation treatment to develop targeted,effective therapy plan and rehabilitation goals,establish individualized treatment of rehabilitation,and to observe the effect of limb movement function in stroke patients. Methods Sixty cases patients with stroke and aged from 40 to 65 years old were selected. The body function and structure of all stroke patients were marked by comprehensive evaluation scores of The National Institutes of Health Stroke Scale ( NIHSS ) and Fugl?Meyer assessment. And then they were randomly divided into two groups,30 cases in each group. The observation group used the Chinese version of brief ICF Core Sets for evaluation, and set individualized treatment according to the results of the assessment;The control group, according to the conventional rehabilitation process, involved in training routine physical therapy. Again 8 weeks after treatment for patients with evaluation,the assessment results was compared with the results of the first assessment. Results Before treatment, the NIHSS, Fugl?Meyer assessment and Chinese version of brief ICF core elements scale scores for the observation group were 7. 95±2. 37,34. 5±4. 0 and 82. 15±17. 96,for the control group were 7. 58±2. 25,34. 8±4. 0 and 81. 55±18. 78. After treatment,the above three rating scale scores, for the observation group were improved to 4. 78 ± 1. 63, 56. 3 ± 4. 2, 60. 45 ±11. 04,for the control group were improved to 5. 13±1. 75,48. 1±3. 8,73. 56±16. 89. The two groups were significantly improved ( observation group:t=4. 94, 15. 51, 18. 59, P<0. 05;control group:t=3. 17, 14. 66, 12. 33,P<0. 05). After treatment,compared with the control group of three rating scale scores(5. 13±1. 75,48. 1
±3. 8 and 73. 56±16. 89),the observation group(4. 78±1. 63,56. 3±4. 2 and 60. 45±11. 04) improved more apparently(t=3. 15,14. 54,15. 45,P<0. 05) . Conclusion Guided by the idea of ICF and scale,with the demand of the patients as the center,to develop personalized physical therapy,can achieve more productive and more targeted rehabilitation goals.

Objective To explore the clinical effect of microgranular fat obtained by mechanical injection of autologous fat tissues in the treatment of lacrimal trough deformity.Methods Ten patients in this group were women,and the average age was 28 years.With tumescent technique,the thigh fat granules were aspirated;after the separation and purification using cell sorting screen,fat particles were obtained with uniform size and without fibrous tissue.Through mechanical pushing of the fat particles,the fat granules became chylomicron-like.The fat particles without fibrous tissue were injected into the superficial layer and deep layer of the orbicularis oculi muscle with depressed deformity.3-12 months after operation,the clinical efficacy was evaluated by doctors,patients and the third party.Results In 10 cases of lacrimal groove deformity,9 cases were transplanted once,and 1 case did twice.After 3 to 12 months follow-up the appearance of tear trough deformity was significantly improved,the texture of the ditch of eyelid and cheek skin was soft,and appeared young plump appearance.There were no complications,such as infection,hematoma,fat liquefaction,pigmentation and induration,and satisfactory results were obtained.Conclusions Ultrafine particles of fat are obtained using improved purification method in the treatment of lacrimal groove deformity,and the efficacy is satisfactory.

Objective To compare two different gastric tube insertion methods on neonatal pain responae.Methods From April to July 2010,47 neonatal patients underwent gastric tube insertion in the neonatal department of our hospital were randomly classified into two groups:the nasal gastric tube insertion group(28 cases) and the oral gastric tube insertion group( 19 cases).Neonatal pain score and incidence of complications during gastric tube insertion between both groups were compared.Results The mean rank of pain scores were significantly higher in the nasal gastric tube insertion group than in the oral gastric tube insertion group.The incidence of pain and complications were higher in the nasal gastric tube insertion group than in the oral gastric tube insertion group.Conclusions The impact of oral gastric tube insertion on neonatal pain response is not significant,and few complications occur during oral gastric tube insertion,so it is worthy of clinical application.
