Objective To investigate the effects of simvastatin pretreatment on ischemia-reperfusion (I/R)injury to the spinal cord in rats. Methods Ninety-six healthy male SD rats weighing 220-280 g were randomly divided into 3 groups (n=32 each): Ⅰ group sham operation (group S); Ⅱ group I/R and Ⅲ group simvastatin pretreatment (group Si). The animals were anesthetized with 10% chloral hydrate 0.4 ml/100g. I/R to the spinal cord was induced by cross-clamping the aorta below renal artery for 45 min followed by reperfusion according to Zivin in group Ⅱ and Ⅲ. In group Ⅲ simvastatin 20 mg/kg was administered via gastric tube in the morning for 3 days before operation. Neurological function was assessed and scored (0 = no spontaneous movement of the hindlimbs, 7 = normal gait) at 2, 6, 12 and 24 h (n = 8 at each time point). The animals were then sacrificed and the lumbar segment (L2-5) of the spinal cord was removed for microscopic examination and determination of expression of TLR4 mRNA, NF-κB protein activity and TNF-α and ICAM-1 contents in the spinal cord. Results I/R to the spinal cord significantly increased TLR4 mRNA expression, NF-κB protein activity and TNF-α and ICAM-1 content in the spinal cord and decreased neurological scores in group Ⅱ compared with group C. Simvastatin pretreatment significantly attenuated the I/R-induced increase in the above-mentioned variables and ameliorated I/R-induced neurological dificit and histopathological damage. Conclusion Simvastatin pretreatment has neuroprotective effects on the spinal cord against I/R injury by attenuating inflammatory response.

Objective To study the expression of the fused proteasome activator REGγ(11S regulator complex gamma subunit) using gene recombination technology and to further study the interaction between REGγ and casein kinase-2 interacting protein-1(CKIP-1)in vitro.Methods Firstly, the full length cDNA fragment of REGγ was amplified through PCR using the plasmid pCMV-Myc-REGγ as template and subcloned into the prokaryotic expression vector pGEX-4T-2 before being transformed into E.coli BL21 cells. The protein expression was induced by isopropyl-β-D-thiogalactoside(IPTG) .Secondly, the protein expression was monitored by SDS-PAGE and Western blotting after ultrasonication. Finally, the GST Pull-down assay was performed to investigate the interaction between REGγ and CKIP-1 in vitro.Results The prokaryotic expression construct pGEX-4T-2-REGγ was generated successfully and confirmed by DNA sequencing. Expression analysis showed that the GST-REGγ protein was easily expressed and isolated mainly in the lysate supernatant after sonication and centrifugation. The GST Pull-down assay revealed the strong mutual interaction between REGγ and CKIP-1 in vitro.Conclusion The proteasome activator REGγ could interact with the negative regulator of osteoblastogenesis CKIP-1 in vitro and the current study has shed light on further investigations of their physiological relevance.

Objective: To investigate the relationships between constitutional types of traditional Chinese medicine (TCM) and motion sickness. Methods: A survey of TCM constitutions in ocean sailors participating in a voyage was performed by using the TCM Constitution Questionnaire developed by Beijing University of Traditional Chinese Medicine, while the survey of motion sickness was operated by Graybiel's diagnostic criteria. The incidences of motion sickness among sailors with different types of constitutions were compared. Results: Prior to the voyage, 50.3% of sailors exhibited a gentleness constitution, 14.5% were of dampness-heat constitution, 10.3% were of qi-stagnation constitution, whereas the percentages of qi-deficiency, yang-deficiency, yin-deficiency, blood-stasis and special diathesis constitutions were 6.2%, 7.6%, 6.2%, 4.1% and 0.7%, respectively. None exhibited a phlegm-dampness constitution. By the end of the 176-day voyage, the percentages of gentleness, dampness-heat, qi-depression, qi-deficiency, yang-deficiency, yin-deficiency, blood-stasis, special diathesis and phlegm-dampness constitutions were 33.8%, 13.8%, 13.1%, 11.0%, 6.9%, 9.7%, 4.1%, 0.7% and 6.9%, respectively. The incidence of motion sickness was 69.7% (101 sailors) during this voyage. The incidences of motion sickness among sailors with different types of constitutions before the voyage showed significant difference (P<0.001). The incidence of motion sickness was higher in the sailors with dampness-heat constitution than in those with gentleness constitution. Conclusion: Types of Chinese medical constitution can be related to susceptibility to motion sickness. Furthermore, ocean voyage may have an effect or influence on the type of Chinese medical constitution of sailors involved.

Objective To investigate the risk factors of acute kidney injury following coronary artery bypass graft(CABG).Methods Twenty-six patients suffering from acute kidney injury following CABG as the patient group and 59 individuals without impairment of renal function as the control from January 2008 to September 2012 in the First People's Hospital of Yichang according to a retrospective case-control study and nonconditional multivariable Logistic regression analysis method..Results Among the 85 patients undergoing CABG,26 suffered acute kidney injury following CABG with a morbidity rate of 30.59％.Identified risk factors for acute kidney injury following CABG included pre-operative mederale-sever cardiac insufficiency,prolonged mechanical ventilation,prolonged stay in ICU and anemia before surgery.The identified independent risk factor of acute kidney injury following CABG was pre-operative mederale-sever cardiac insufficiency (OR =3.206,95％ CI:1.067-9.631).Condusion Pre-operative mederale-sever cardiac insufficiency was an independent risk factor of acute kidney injury following CABG.

Objective To discuss the reoperation method for recurrent pituitary apoplexy after the successful initial transnasal-sphenoidal surgery.Methods Twenty-one patients with pituitary apoplexy were found recurrence after previous tumor resection via transsphenoidal surgery in 9 months to 5 years.In the reoperation,transsphenoidal approach would be still used.The anterior wall of sphenoid sinus and the sellar floor were located accurately,and then the remnants of them were removed as large as possible to expand the range of bone window.Next,the intrasellar hematoma was cleared away gently,and the residual tumor was removed progressively and thoroughly to make sure the sellar diaphragm subsiding fully and finally removed the whole tumor.Results Most of recurrent tumors were found to be of soft texture with rich blood supply,and 17 cases were still apoplexy.In 18 cases of the 21 patients,total resection was achieved.However,for the other 3 cases with tumor aggressive growth,only massive resection was achieved,and underwent stereotactic radiosurgery postoperatively.Postoperative clinical symptoms were alleviated in 15 cases,whose hormones were also decreased.Temporary diabetes insipidus and hypopituitarism appeared in 5 and 3 cases respectively,but all of these postoperative complications were relieved after symptomatic treatment.Two cases of intraoperative cerebrospinal fluid leakage were resolved by packing the cavity with muscle and fat flaps.All cases were followed up for 3 months- 5 years,residual tumor enlarged in only 1 case of massive resection,which umderwent transsphenoidal surgery for the third time,no other cases recurred.Conclusion Operation via the transsphenoidal approach of recurrent pituitary apoplexy after successful initial transsphenoidal surgery could achieve high total resection rate.While the accurate locating,full expansion of the saddle bone window,and repeatedly scraping the apoplexy tumor to get a full subsidence for the sellar diaphragm,are the key points to remove tumors totally as well as to improve the symptoms.

Evaluation of the permeability mainly focuses on intestinal absorption in biopharmaceutics classification system (BCS). It is more complicated that the absorption and metabolism under multicomponent environment in biopharmaceutics classification system of Chinese materia medica (CMMBCS) compared with single component environment, which needs suitable mathematical models to be described. Therefore, with full consideration of existing single component mathematical algorithm combining with the characteristics of intestinal absorption and metabolism, we explored and designed a new mathematical algorithm of intestinal absorption and metabolism of multicomponent drug. Then we put forward a new coefficient, P (influence), the relative change rate of the single component's intestinal absorption and metabolism under multicomponent environment compared with single component environment, which described the influences of intestinal absorption and metabolism of the component under multicomponent environment. Moreover, P (influence) highlights the distinctive characteristics of multicomponent drug's intestinal absorption and metabolism, and lays the foundation for the construction of CMMBCS.
