Objective To observe the therapeutic efficacy of electroacupuncture with different waves in treating neurogenic bladder due to spinal cord injury (SCI). Method Totally 108 patients with SCI-induced neurogenic bladder were randomized into 3 groups, 36 cases in each group. Same acupoints were selected for the three groups, but continuous wave, sparse-dense wave and discontinuous wave were respectively used after needling qi arrival. The symptoms score and urodynamic indexes were observed before and after the intervention. Result The total effective rate was 80.6%in the sparse-dense wave group, better than that in the continuous wave group and discontinuous wave group. The sparse-dense wave group produced a more significant effect in reducing the urethral closure pressure, abdominal pressure, functional urethral length, and urethral control length (P<0.05); there were no significant inter-group differences in comparing the effect in increasing the urinary flow rate (P>0.05). The discontinuous wave group produced a more significant effect in increasing the bladder pressure (P<0.05,P<0.01); the effect in lowering the bladder pressure was more significant in the continuous wave and sparse-dense wave groups than in the discontinuous wave group (P<0.01). Conclusion The three types of electroacupuncture wave can produce different regulatory effects on the body. The continuous wave is the most adaptable one but plays the least effect;the sparse-dense wave is closer to bioelectricity of human body and produces the most significant effect;the discontinuous wave produces the most significant effect in activating nerves and muscles, as well as in improving bladder weakness.

BACKGROUND:Volar locking plate is the domin Pedicle screw placement for spinal fractures with X-ray and CT assistant can optimize the accuracy of screw placement.Additionally,X-ray is cheap,repetitive and can reduce radiation injury,but has not been confirmed.OBJECTIVE:To evaluate the effect and imaging evaluation of X-ray in pedicle screw placement for spinal fractures.METHODS:Twenty patients with spinal fractures at T1-8 levels in our hospital from November 2014 to December 2016 were enrolled.The needles were placed along the pedicle axis at the middle of the pedicle,vertebral posterior and vertebral anterior,and its position was recorded by C-arm X-ray,100 pedicle screws were placed under C-arm X-ray,and then evaluated by CT to analyze the application effect of X-ray.RESULTS AND CONCLUSION:The screw length between the actual placement at T1,T2,T3,T4,T5,T6,T7,T8 screw length under C-arm X-ray and virtual ones had no significant differences (P ＞ 0.05),suggesting that X-ray can optimize the accuracy of screw placement.A total of 100 screws were placed,94 screws were excellent,which were placed into the vertebral body completely,and the direction and depth were in accordance with the requirements.Six screws were good,some screws slightly worn out,but the cortical bone was less,and none was poor.No accident of pedicle violations was found.To conclude,C-arm X-ray-assisted screw placement for spinal fractures exhibits ideal outcomes.

BACKGROUND: Scoparone,which is a major principle separated from traditional Chinese herbs artemisia scoparia, which possesses actions of immunosuppression, anti-inflammation and relaxing bronchial smooth muscle. It' s not known whether scoparone possesses the regulation of the imbalance of interferon-gamma(IFN-γ) and interleukin-4(IL-4) in asthmatic guinea pig.OBJECTIVE: To investigate the inhibition and immunoregulation of scoparone on asthmatic guinea pig.DESIGN: Randomized controlled study based on the experimental animals.SETTING: Department of ethnopharmaeology in a university.MATERIALS: The experiment was completed in the Department of Ethnopharmacology,China Medical University between July 2000 and March 2002. Totally 84 male guinea pigs were selected at sanitation grade,weighting about(200 ± 50) g.INTERVENTIONS: The ameliorative effects of scoparone on the imbalance of IFN-γ and IL-4 in asthmatic guinea pigs were investigated by using the acute and delayed asthmatic guinea pigs which were respectively challenged by the aerosol mixture of 10 g/L histamine and 1 g/L acetylcholine,and 10 mL/L ovalbumin.MAIN OUTCOME MEASURES: The asthmatic latent periods in acute and delayed asthma, and the levels of IgE, IL-4 and IFN-γ in serum and pulmonary tissue homogenate in the asthmatic animals.RESULTS: Scoparone significantly prolonged the asthmatic latent periods in acute and delayed asthma,observably reduced the levels of IgE and IL-4 and raised the content of IFN-γin serum and pulmonary tissue homogenate in the asthmatic animals (P<0. 05).CONCLUTION: The anti-asthmatic effects of scoparone result from the ameliorative effects on the imbalance of IFN-γ/IL-4 ratio thereby to inhibit the abnormal synthesis of IgE.

BACKGROUND: Previous studies have shown that the complex of polyethylene glycol diacrylate and chitosan is biodegradable, has the anti-inflammation effect and can promote wound healing, with good biocompatibility.However, the composite material is brittle, and thus, it is necessary to develop a mechanical support material due to the anatomy of the nasal cavity.OBJECTIVE: To study the cytocompatibility of a novel degradable absorbable nasal packing material made of polyethylene glycol diacrylate composite hydrogel.METHODS: In our experiment, the composite hydrogel was formed by the combination of different ratios of polyethyleneglycol diacrylate, chitosan and polyvinyl alcohol using photo-crosslinking method. According to the international standard of medical devices, we used direct and indirect international standard experimental methods to evaluate the cytotoxicity of the materials. (1) Direct contact method: the polyethylene glycol acrylate composite hydrogel and mouse fibroblasts L929 were co-cultured for 24 hours to observe the morphological changes of cells. (2) Indirect extraction: mouse fibroblasts L929 were cultured in polyethylene glycol diacrylate composite hydrogel extracts (100, 50 μL) and RPMI1640 medium (100 μL), respectively, for 3 days to observe the proliferation and cytotoxicity by cell counting kit-8 assay.RESULTS AND CONCLUSION: (1) Direct contact method: the cells around the material formed a flat structure with fusiform or stellated protrudes. The material was confirmed to have good biocompatibility depending upon the presence of adherent cell growth, full and strong refraction, and the overall growth trend. (2) Indirect extraction method: with the increase of time, the number of cells in the hydrogel extract group increased, the relative proliferation rate of cells increased gradually, and the cytotoxicity was 0 to 1. To conclude, these experimental findings indicate that the polyethylene glycol acrylate composite hydrogel material has good cytocompatibility.

Fructose-1, 6-bisphosphatase (FBPase), a rate-limiting enzyme involved in the pathway of gluconeogenesis, can catalyze the hydrolysis of fructose-1, 6-bisphosphate to fructose-6-phosphate. Upon inhibiting the activity of FBPase, the production of endogenous glucose can be decreased and the level of blood glucose lowered. Therefore, inhibitors of FBPase are expected to be novel potential therapeutics for the treatment of type II diabetes. Recent research efforts were reviewed in the field of developing allosteric inhibitors interacting with the AMP binding site of FBPase.

Aim The m_5AChR-G_ 11? fusion protein was expressed by baculovirus-Sf9 cells system, then using it to identify the specific agonists and antagonists for m_5AChR via detecting the affinity of GDP and m_5AChR-G_ 11?. Methods The m_5AChR-G_ 11? fused cDNAs were generated via a two-step PCR protocol and inserted into pBacPAK9 virus vector. We expressed m_5AChR-G_ 11? fusion protein and m_5AChR protein using baculovirus-Sf9 cell system. [ 3H]QNB and [ 35S]GTP?S binding tests were performed to detect the expressional level of receptor proteins and determine the affinity of GDP and m_5AChR-G_ 11? fusion protein. Results The expression level of m_5AChR-G_ 11? was (47.6?3.2) nmol?g -1 protein. The affinity of GDP to G_ 11? partner changed in the presence of different muscarinic ligands. IC_ 50 values of GDP in the presence of ACh, YM796, Oxotremorine, Methixene, Dextimide and atropine were 128.0, 72.1, 68.5, 16.2, 14.9 and 9.7 ?mol?L -1 respectively, and that in the absence of muscarinic ligand was 20.8 ?mol?L -1. Conclusion The m_5AChR-G_ 11? fusion protein has the pharmacological specificity of M_5 receptor and the efficient coupling interaction of the two partner. Affinity of GDP to ligand bound m_5AChR-G_ 11? fusion protein represents the species of muscarinic ligands. ACh is a full agonist for m_5AChR-G_ 11? fusion protein, YM796 and oxotremorine are partial agonists, while methixene, dextimide and atropine are antagonists.

Objective To investigate the relationship between admission blood glucose and in-hospital adverse events of elderly patients with non-ST-segment elevation myocardial infarction(NSTEMI) combined with multi-organ dysfunction in emergency department,and to assess the prognostic value.Methods Fifty-one geriatric patients with NSTEMI combined with multi-organ dysfunction were selected and divided into the experimental group (26 cases) and control group (25 cases),depending on whether they had adverse events in hospital.After the propensity score matching was used to reduce confounding effects,the difference in admission blood glucose between the two groups was compared.According to the ROC curve,the predictive value of immediate admission blood glucose to the incidence of adverse events during hospitalization was detected.Results After propensity score matching,admission blood glucose of the experimental group ((10.35±4.06) mmol/L) was higher than that of the control group ((7.05±2.45) mmol/L),and this difference was statistically significant (t=2.869,P<0.01).The area under the ROC curve for adverse events during hospitalization was 0.758 (P<0.01),and it may reach the best prognostic value when we choose 8.025mmol/L as the critical value.Under this condition,the sensitivity was 0.765 and specificity was 0.765.Conclusion For geriatric patients with NSTEMI combined with multi-organ dysfunction in emergency department,admission blood glucose is a risk factor for in-hospital adverse event,and the risk is high when admission blood glucose is over 8.025mmol/L.
