Objective: To explore the urgent management strategy for quadriplegia following China Wenchuan earthquake under filed condition. Methods: The 57-year-old male patient was sent to the earthquake relief team of Changzheng Hospital, Second Military Medical University. He was hit by heavy object during the Sichuan earthquake 6 days ago. Physical examination revealed cervical spinal cord injury accompanied by incomplete paralysis. The patient underwent cervical 3-7 laminectomy under general anesthesia. Results: After surgery the muscle strength of lower limbs recovered to grade four from grade one; the muscle strength of upper limbs recovered to grade five from grade three. Sensory loss was found below the nipple level and totally recovered after operation. Conclusion: Early surgery for quadriplegia following earthquake trauma can timely relieve compression to the spinal cord and therefore improve prognosis of patients. Under field condition where facilities are not readily available, decompression of spinal cord can be achieved by laminectomy via posterior approach. The key to successful operation is correct diagnosis and skillful manipulation.

AIM: To compare the contents of baicalin,paeoniflorin and glycyrrhetic acid in the seperated and mixed decoction of Huangqin Decoction(Radix Scutellariae,Radix Paeoniae alba,Radix et Rhizoma Glycyrrhizae and Fructus Jujubae). METHODS: The contents of baicalin,paeoniflorin and glycyrrhetic acid were analyzed by HPLC.Chromatographic conditions included: Hypersil BDS C_(18) column and the mobile phase consisted of a mixture of methanol-water-phosphoric acid(47(∶)53(∶)0.2),acetonitrile-water-phosphoric acid(18(∶)82(∶)0.1) and methanol-water-phosphate buffer solution(70(∶)29(∶)1).Baicalin,paeoniflorin and glycyrrhetic acid were detected at 280 nm,230 nm and 250 nm respectively. RESULTS: The linear range of baicalin,paeoniflorin and glycyrrhetic acid were 2.88—72.00 ?g/mL,2.85—22.80 ?g/mL and 4.16—52.00 ?g/mL respectively.The contents of baicalin in the mixed decoction was higher than that in the seperated decoction.The contents of paeoniflorin and glycyrrhetic acid in the mixed decoction were almost as same as that in seperated decoction. CONCLUSION: The contents of active ingredients in the mixed and seperated decoction are different.

Objective To investigate the effect of the nuclear factor (NF)-κBp65 antisense oligonucleotide (ASODN) on NF-κB activity and expression of interleukin(IL)-6 in hepatic stellate cells (HSC). Methods The HSC were separated from rats and cultured. The toxicity of NF-κBp65 ASODN on HSC were detected by Trypan blue exclusion staining and the NF-κB activity was determined by EMSA. The expressions of IL-6 mRNA and protein were meaured by RT-PCR and ELISA, respectively. Results In vitro, no toxicity of ASODN on HSC was observed at the concentrations of 0. 001 to 1.0 μmol/L. NF-κB activity was increased after stimulating HSC with tumor necrosis factor (TNF)α, whereas it was weakened in a dose dependent manner when HSC were cultured with ASODN (concentration from 0. 001 to 1.0 μmol/L). At the same time, the expressions of IL-6 mRNA and protein induced by TNFα were decreased after transfected with ASODN at concentrations of 0.001- 1. 0 μmol/L in a dose dependent manner. Conclusion ASODN may specifically inhibit either the activiy of NF-κB or expression of IL-6, which provides the theoretical basis that ASODN may use to treat fibrosis of the liver.

Objective To explore the efficacy and safety of Gemcitabine and Cisplatin combination chemotherapy in treatment of muscle-invasive urothelial cell carcinoma.Methods Analyse of 72 cases of patients with muscle-invasive urothelial cell carcinoma receiving chemotherapy from September 2010 to September 2012,including 47 male and 25 female,the avarage age was 65 (86-33).All patients were received GC chemotherapy (Gemcitabine 800-1 000 mg/m2,ivgtt,dl,d8,d15; Cisplatin 70 mg/m2,ivgtt,d2).Efficacy was reviewed after 1 cycle of chemotherapy.Results Fifty-one cases in all the patients completed two or more chemotherapy cycles and CR 10 cases,PR 27 cases,total effective rate was 51.39％ (37/72).The main toxic reactions included nausea,vomit,myelosuppression,and then damage of liver and renal function.Cconclusion GC regimen is a good choice for urothelial cell carcinoma.Close follow-up and the usage of adjuvant drugs can contribute to reduce the side effect of chemotherapy.

Background Hypoxia is a crucial factor of neovascularization.Many researches found that stromal cell-derived factor-1 (SDF-1) and integrin-linked kinase (ILK) play an important role in the neovascular disease.However,effect of SDF-1 and ILK in eye neovascular disease is below understood.Objective The aim of this study was to investigate the effect of hypoxia on the expressions of SDF-1 and ILK in cultured retinal pigment epithelium(RPE) cells in vitro.Methods RPE tissue was isolated from 4-week-old C57BL/6 mouse and was digested and cultured in DMEM/F12 with 10％ fetal bovine serum (FBS).The cells with 80％ confluence were collected and passaged.The third generation of cells were identified with cytokeratin 18 (CK18) antibody by immunochemistry.The cells were inoculated at the density of 5×104 cells/ml to free-serum DMEM/F12 for 24 hours and then were cultured in regular medium in the normoxic control group.RPE cells were cultured for 1 hour and 3,6,12,24,48,72 hours with 200 μmol/L CoCl2 in the hypoxia group.Reverse transcription-PCR(RT-PCR) was used to evaluate the expressing change of SDF-1 mRNA and ILK mRNA in RPE cells,and Western blot was used to assay the expressing change of SDF-1 protein and ILK protein in RPE cells in different time points.The detected outcomes were represented as the ratio of target gene A value/β-actin A value.Results Cultured cells showed the polygon in shape with the black pigment granules in cytoplasm.Over 90％ cells were positive response for CK18.Expressions of the SDF-1 mRNA and ILK mRNA were increased in different time points after CoCl2 co-cultured(SDF-1 mRNA:F=281.875,P=0.000 ;ILK mRNA: F=187.566,P=0.000),with the highest expressing value in hypoxia at 12 hours.No significant change in the expression of SDF-1 mRNA and protein was found 1 hour after CoCl2 co-cultured,but expressions of SDF-1 mRNA and ILK mRNA were significantly higher in 3,6,12,24,48 and 72 hours than the normoxic control group(P＜0.01).The expressions of SDF-1 protein and ILK protein were gradually ascended with the time increase of CoCl2 co-culture,showing a significant difference among different time points(SDF-1: F=44.719,P =0.000 ; ILK: F =144.481,P =0.000),and the up-regulation of SDF-1 protein and ILK protein expression was seen mainly in 3,6,12,24,48 and 72 hours after CoCl2 co-cultured in comparison with the normoxic control group (P＜0.01).Conclusions SDF-1 and ILK are involved in the hypoxic response of RPE cells and may play a potential role in ischemic/hypoxic retinopathy.

Objective To investigate the clinical characteristics and treatmentof ureteral endometriosis.MethodsA retrospective analysis was made on the clinical data of 16 cases of ureteral endometriosis of the Department of Vrology,Beijing Friendship Hapital,Affiliated to Copital Medical Universty from January.1991 to Augest.2011.ResultsSixteen cases were pathologically confirmed endometriosis,including 11 cases of outer lumen type,5 cases of lumen type ; endomctriosis lesions were all located in the lower ureter.Ureteral stricture length was 1.0-4.0 cm.During 12 months to 20 years follow-up,hydronephrosis detected by ultrasonography in 15 patients was released significantly,and no recurrence occurred except one case who was found hydronephrosis 3 years later.Ureter anastomosis was undergone later.ConclusionsUreteral endometriosis onset is undetectable which could impact renal function.Renal ultrasonography can reduce misdiagnosis.The principle of treatment is to remove the obstruction and protect renal function,and well follow-up to prevent recurrence.

Objective To study the relationship between the OATP1B1 521T ＞ C genetic polymorphism and essential hypertension.Methods 164 essential hypertension subjects and 159 normotensive subjects were detected by the TaqMan-MGB probe real-time fluorescence quantitative PCR,and the results were compared with those of DNA sequencing.Results The frequencies of T/C genotype and C allele of OATP1B1 521T ＞ C gene of the essential hypertension subjects were obviously lower than those of the normotensive subjects(T/C genotype:0.16 vs 0.25,P ＜0.05 ;C allele:0.10 vs 0.17,P ＜0.05),The difference was significant.Binary logistic stepwise regression analysis was used for evaluatine the risk factors of essential hypertension,there was significant relationship between OATP1 B1 52IT ＞ C gene polymorphism and essential hypertension.Conclusion The SLCO1 B1 521T ＞ C variant was common in Chinese essential hypertension population,but the difference of frequency of SLCO1B1 52IT ＞ Cmuton between the essential hypertension patients and the normotensive controls was of obviously statistical significance,which indicates that the SLCO1B1521T ＞ C variant maybe associate with essential hypertension.
