OBJECTIVETo investigate the placement of a long tube into the small intestine under fluoroscopic guidance and to evaluate its decompression effect on early postoperative small bowel obstruction (EPSBO).

METHODSFifty-four patients with EPSBO requiring decompression between April 2010 and July 2014 were enrolled in the study. Insertion of a long tube was guided by fluoroscopy. We first used the guide wire to pass the pylorus and then used the 10 Fr feeding tube as an exchangeable tube to put the superstiff wire into the duodenum. Finally the long tube could be passed over the guide wire through the pylorus into the intestine. The total procedure time, the radiation exposure time, and the incidence of complications were evaluated.

RESULTSThe long tubes passed into the jejunum on initial insertion for all patients, so the success rate of this technique was 100%. The long tube was inserted into ileum in 18 patients. The mean total procedure time was 34.4 ± 8.6 minutes, and the mean radiation exposure time 18.9 ± 6.8 minutes. A total of 47 patients (87%) experienced full recovery following long-tube decompression and without the need for surgical intervention.

CONCLUSIONSUsing the wire-exchange technique, it is easy to place a long tube into the small bowel under fluoroscopic guidance. This decompression method is safe and effective for management of EPSBO.

OBJECTIVETo observe the expression of Ginkgo biloba Tablet (GbT) on scavenger receptor A (SRA) of the aortic wall and changes of serum inflammatory factors in atherosclerotic rats, and to explore its new mechanism for fighting against atherosclerosis (AS).

METHODSTotally 45 male Wistar rats were randomly divided into the control group, the model group, the GbT group, 15 rats in each group. Levels of blood glucose, blood lipids, blood calcium, serum C-reactive protein (CRP), soluble intercellular adhesion molecule-1 (slCAM-1), and soluble vascular cell adhesion molecule-1 (sVCAM-1) were measured in all rats. The expression of SRA in the aortic wall of atherosclerotic rats was observed by immunohistochemical assay. The correlation between the expression of SRA and levels of in-flammatory factors was also observed.

RESULTSCompared with the control group, blood glucose and blood calcium obviously increased (P < 0.05); levels of TG, TC, and LDL-C were significantly elevated (P < 0.01); neointimal areas were significantly thickened, increased intima percentage was significantly enlarged, narrowed lumen index was significantly reduced; levels of CRP, sICAM-1, and sVCAM-1 were significantly elevated in the model group (all P < 0.01). Compared with the model group, blood glucose and blood calcium obviously decreased (P < 0.05); levels of TG, TC, and LDL-C significantly decreased (P < 0.01) in the GbT group. Aortic lumens were obviously narrower in the model group than in the GbT group (P < 0.05). SRA expressed at the aortic wall. The aforesaid 3 indices were significantly improved in the GbT group than in the model group (P < 0.01). Serum levels of CRP, sICAM-1, and sVCAM-1 were significantly decreased in the GbT group than in the model group (P < 0.01). Serum levels of CRP, sICAM-1, and sVCAM-1 were positively correlated with the percentage of SRA positive expression area (r = 0.701, 0.604, 0.581, all P < 0.01).

CONCLUSIONSSerum levels of inflammatory factors in atherosclerotic rats were elevated, and the expression of SRA in the aortic wall was enhanced. The expression of SRA was closely correlated with serum levels of inflammatory factors. GbT could decrease serum levels of inflammatory factors and inhibit the expression of SRA.

OBJECTIVETo discuss operative methods and effects for Müller-Weiss disease.

METHODSFrom March 2005 to May 2011, 15 patients were operated. There were 2 males and 13 females, with an average age of 51.8 years (range, 26 to 62 years). The preoperative American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score was (42 ± 13) points. According to the Maceira Staging system, 1 foot was grade 2, 6 feet were grade 3, 4 feet were grade 4, and 4 feet were grade 5. The technique consisted of arthrodesis of the talonaviculocuneiform joints with plate, arthrodesis of the talonavicular joint and arthrorisis of naviculocuneiform joint with plate, or triple arthrodesis with screws, according to the preoperative evaluation.

RESULTSTen feet were treated with arthrodesis of the talonaviculocuneiform joints, 3 feet were treated with arthrodesis of the talonavicular joint and arthrorisis of naviculocuneiform joint and 2 feet were treated with triple arthrodesis. Two patients were lost to follow-up. The average follow-up after operation was 19.2 months (range, 9 to 38 months). All feet were solid fusion and the average duration of union was 13.3 weeks (range, 12-16 weeks). The AOFAS ankle-hindfoot score at the last follow-up was (83 ± 6) points. Two feet were excellent, 10 feet were good, and 1 foot was fair. The length of feet was (14.2 ± 1.0) cm before surgery and (15.7 ± 0.9) cm at the last follow-up (t = 11.570, P < 0.05). The Meary's angle was -6.1° ± 13.1°before surgery and 1.1° ± 3.0° at the last follow-up (t = 2.248, P < 0.05). The talocalcaneal angle was 4.5° ± 2.2° before surgery and 18.0° ± 4.0° at the last follow-up (t = 11.700, P < 0.05). One foot had breakage of the plate and screws at arthrorisis of naviculocuneiform joint and none had complications related to the incision.

CONCLUSIONOperations for Müller-Weiss disease, according to concrete conditions using different therapeutic program, may achieve a satisfactory outcome.

Objective To investigate the expression of peroxisome proliferators-activated receptor ? (PPAR?) in trophoblast and relation between PPAR? ligands and trophoblast invasion.Methods We examined the expression of PPAR? by immunohistochemistry,immunocytochemistry and real time quantitative PCR.We next examined,using the cytotrophoblast culture model,the biological role of PPAR? ligands in vitro.Results PPAR? was mainly localized in the nuclei of villous cytotrophoblast and extravillous cytotrophoblast of cell islands and cell columns.In villous tissue and cultured trophoblast from early first trimester,the level of expression of PPAR? mRNA and protein was 36.0?5.1,13.4?3.1 and 1.35?0.08,1.13?0.11;from late first trimester it was 23.3?5.5,6.1?1.3 and 1.17?0.03,0.86 ?0.05,and the expression of PPAR? was obviously decreased (P

Objective To evaluate the association of islet autoantibodies [ glutamic acid decarboxylase antibody(GADA),protein tyrosine phosphatase antibody(IA-2A)and insulin autoantibodies(IAA)1 with HLA- DQ genotypes in the first-degree relatives of autoimmune type 1 diabetes mellitus.Methods This was a cross- sectional and case-control study.Three hundred and fifty-one first-degree relatives with normal glucose tolerance of patients with type 1 diabetes mellitus and 376 healthy controls were recruited and measured for GADA,IA-2A and IAA by radioligand assay,and 156 first-degree relatives of patients with autoimmune type 1 diabetes mellitus and 278 controls were typed for genetic polymorphisms of HLA-DQ with PCR sequencing-based typing method.Results (1)DQA1*03,DQBI*0303,*0401 alleles and DQA1 * 03-DQBI * 0303,DQA1 * 05-DQBI * 0201,DQA1 * 03-DQBI * 0401 haplotypes were significantly increased in the first-degree relatives of autoimmune type 1 diabetes mellitus(P

This study was aimed to investigate whether hydroquinone (HQ) can inhibit NF-kappaB expression activated by phorbol myristate acetate (PMA), and to explore the relationship between the mechanism and the hematology toxicity of benzene tentatively. The human bone marrow stromal cells (BMSC) were harvested by in vitro culture and their change of morphology were observed. The activity and protein expression of NF-kappaB p65 extracted from those BMSC were measured with immunohistochemistry and TransAM P65 kit. The results showed that in cells exposed to HQ, P65 transferred from cell nucleus to cytoplasma around cell nucleus and its concentration lowered by immunohistochemistry. And TransAM P65 kit assay revealed that HQ effects at different concentrations were distinctive at respective time. The detected parameters in 100 micromol/L HQ group were significantly different from control group after exposure for 72 hours. But the parameters at different time in micromol/L HQ group were not obviously different. It is concluded that hydroquinone can inhibit NF-kappaB activated by PMA in BMSCs culture. This kind of inhibitory action correlated with the concentration of HQ and exposure time.

OBJECTIVETo study the effect of Modified Guipi Decoction (MGD) on blood pressure and quality of life (QOL) in hypertension patients complicated depression.

METHODSTotally 245 hypertension patients complicated depression were randomly assigned to the treatment group (125 cases, treated with MGD) and the control group (120 cases, treated with Sertraline). Final recruited qualified patients were 117 cases in the treatment group and 111 cases in the control group. The therapeutic course for all was 4 weeks. Changes of blood pressure, scores rated by Hamilton Depression Scale-17 (HAMD-17), Hamilton Anxiety Rating Scale (HAMA), short-form 36 health survey questionnaire (SF-36), and Treatment Emergent Symptom Scale (TESS) were observed before and after treatment, thereby judging their efficacies.

RESULTS(1) Compared with before treatment in the same group, systolic and diastolic blood pressures significantly decreased in the treatment group after 2 weeks of treatment; systolic blood pressure significantly-decreased after 2 weeks of treatment and diastolic blood pressure significantly decreased after 3 weeks of treatment in the control group (all P < 0.05, P < 0.01). Decreased valley values of systolic and diastolic blood pressures at week 2, 3, and 4 after treatment were obviously higher than those at week 1 after treatment in the two groups (P < 0.05, P < 0.01). Compared with the control group at week 4 after treatment, valley value of systolic blood pressure obviously decreased in the treatment group (P <0. 01). Decreased valley values of systolic and diastolic blood pressures in the treatment group were higher than those of the control group (P <0. 01). The success rate of target blood pressure was 60. 7% (71/117 cases) in the treatment group and 42. 3% (47/111 cases) in the control group, with statistical difference (χ² = 7.6781, P < 0.01). (2) Compared with before treatment in the same group, the score of HAMD-17 at week 2, 3, and 4 after treatment all decreased in the two groups (P < 0.01). Compared with the control group, the score of HAMD-17 at week 4 after treatment decreased more obviously in the treatment group, with higher difference in decreased value (P < 0.05). The effective rate was 79.5% (93/117) in the treatment group, higher than that in the control group [66.7% (74/111); χ² = 4.7741, P < 0.05]. (3) Compared with before treatment in the same group, the score of HAMA at week 1, 2, 3, and 4 after treatment all obviously decreased in the two groups (P <0. 05, P <0. 01). Compared with the control group, the score of HAMA at week 3 and 4 after treatment decreased more obviously in the treatment group, with higher difference in decreased value (P < 0.05, P < 0.01). (4) After 4 weeks of treatment, except physical function in the control group, SF-36 total score and the score for each factor were obviously higher in the two groups (P < 0.05, P < 0.01). MGD showed superior effect in improving physical function, physical activity, overall health, emotion activity, and health changes to that of Sertraline (P < 0.05, P < 0.01). (5) The incidence of insomnia, tremor, liability to agitation, dizziness was obviously less in the treatment group than in the control group (P < 0.05).

CONCLUSIONSMGD had favorable clinical effect on hypertension patients complicated depression. Meanwhile, it also could improve their blood pressure and QOL.
