Objective To study the effect of batroxobin combined with Yinxingdamo injection on serum endothelin(ET),nitric oxide(NO),superoxide dismutase(SOD),vascular cell adhesion molecule-1(VEGF-1)in patients with sudden deafness(SVCAM-1),to explore the best treatment for patients with sudden deafness.Methods Ninety patients with sudden deafness from June 2014 to June 2015 were recruited as the subjects of this study.The patients in control group were treated with batroxobin and batroxobin and ginkgo dipyridol.The levels of serum ET,NO,SOD,sVCAM-1,time of symptom recovery and the curative effect were observed.Results After treatment,the levels of ET,NO and sVCAM-1 in the observation group were significantly lower than those in the control group [(64.28±5.72)pg/mL vs(67.36±6.31)pg/mL,(43.08±9.53)μmol/(93.24±11.25)NU/mL](P<0.05).The results showed that there was no significant difference between the two groups.The recovery time of tinnitus,auria and vertigo in the observation group were less than those in the control group [(3.86±1.02)d vs(5.97±1.34),(5.03±1.24)d vs(7.37±2.01)d,(8.09±2.10)d vs 9.07±2.37)d](P<0.05).The total effective rate in the observation group was better than that in the control group(93.33％vs 75.55％,P<0.05).Conclusion Batroxobin combined with ginkgo dipyridolum injection can decrease the level of ET,NO and sVCAM-1,improve the level of SOD,and improve the microcirculation of the inner ear.Compared with the single effect of Batroxobin More desirable,worthy of promotion.

Objective To analyze blood-CSF barrier and cerebrospinal intrathecal IgG synthesis in patients of multiple sclerosis, and explore the Protis software, IgG index and IgG synthesis rate in the and evaluation for cerebrospinal intrathecal IgG synthesis and blood-CSF barrier dysfunction. Methods 134 patients with neurological diseases were divided into threes groups, including multiple sclerosis group (34 cases), disease control group(80 cases) and control group(20 cases). IgG and ALB concentration of CSF and blood was detected by BN-Ⅱ. The oligoclonal IgG was detected by immunofixation electrophoresis. The relationship between Protis software results and IgG index or IgG synthesis rate was calculated and analyzed. Results The function of blood-brain barrier was almost normal in multiple sclerosis group,QALB was 4.5×10-3[(3.1-7.6)×10-3], there was no significance compared with control group (D=5.25, P>0.05). there were 31 patients with oligaclonal bands in cerebrospinal fluids in multiple sclerosis group (34 patients) with the positive rate of 91.2%. In multiple sclerosis group the intrethecal IgGIF, IgG index and IgG synthesis rate of 24 hours were 31.25% (11.65%-71.45 %), 0.93% (0.80%-1.04%), 24.25 mg/24 h(15.25-46.15 mg/24 h) ,the results were all higher than that in control group (D=175.5, 112.5,103.4,P<0.05). And in multiple sclerosis group there was no significant difference among the intrethecal IgGIF, IgG index and IgG synthesis rate of 24 hours, the positive rate of oligaclonal bands (P>0.05). In disease control group(80 patients) QALB Was 35.2×10-3[(18.5-55.5)×10-3] ,the result was significantly higher than control group (D=102.7, P<0.05), the oligaclonal bands were all negative, IgG index and IgG synthesis rate of 24 hours were 0.75(0.69-0.82) ,44.29 mg/24 h(20.35-65.98 mg/24 h) were both higher than control group(D=85.6,98.5,P<0.05). In disease control group the positive rate of intrathecal IgGIF, IgG index and IgG synthesis rate of 24 hours were 0 (0/80), 40.0% (32/80), 72.5% (58/80) respectively, IgG index and its positive rate both increased alone with the lesion degree of blood-brain barrier increasing (P<0.05). And there was similar trend in the IgG synthesis rate of 24 hours. There were significant correlations among intrathecal IgGIF, IgG index and IgG synthesis rate of 24 hours in multiple sclerosis group (r=0.788, 0.695 ,P<0.05). However there was no correlation among intrathecal IgGIF, IgG index and IgG synthesis rate of 24 hours in disease control group (r=0.000,P>0.05). Conclusions The Protis software can be used to analyze the intrathecal IgGIF and reflect the actual status of intrathecal IgG synthesis more accurately. Protis software has great application value for clinical diagnosis for nervous system disease.

Tetrahydrobiopterin (BH4) is an essential cofactor for all three nitric oxide synthase (NOS isoforms), which plays an important role in vascular diseases. GTP cyclohydrolase 1 (GCH 1) is the first-step and rate-limiting enzyme for BH4 biosynthesis in its de novo pathway. Common GCH1 gene variant C+243T in the 3'-untranslated region predicts NO excretion. The present study examined the predictive role of GCH 1 gene 3'-UTR C+243T variant in the long-term outcome of ischemic stroke. A total of 142 patients with first-onset ischemic stroke were recruited and detected for genotype of GCH1 3'-UTR C+243T by a TaqMan SNP Genotyping assay. Subsequent vascular events and death were determined over a 5-year follow-up period. The frequency of GCH1 3'-UTR +243 C/T or T/T genotype was significantly increased in patients with endpoint events as compared with those without events (74% vs 57.8%, P=0.06). Cox regression survival analysis indicated that an increased probability of death or new vascular events was found in patients with GCH1 3'-UTR +243 C/T or T/T genotype compared with those with GCH1 3'-UTR C/C genotype (40.6% vs 25.5%), GCH1 3'-UTR +243 C/T or T/T genotype relative to GCH1 3'-UTR C/C genotype was associated with the increased risk of death or vascular events even after adjustment for other risk factors (OR=2.171, 95% CI: 1.066-4.424, P=0.033). It was concluded that GCH1 3'-UTR C+243T variant was an independent predictor of worsening long-term outcomes in patients with first-onset ischemic stroke.

Objective To investigate the level of five auto-antibodies including MCV and GPI in the serum of RA patients and assess the application value of five auto-antibodies in RA diagnosis.Methods The five auto-antibodies were detected by ELISA in serum samples of 150 patients with RA and 40 healthy controls,32 patients of SLE,30 patients of OA,20 patients of AS,20 patients of SS,20 patients of CTD.Results The positive rates of these five auto-antibodies in RA patients were significantly higher than in other group(X2=88.5,76.0,279.2,88.2,94.8,P＜0.05).Except anti-AKA,there was no the differences in the level of other antibodies among groups(X2=21.9,9.4,20.2,43.2,41.6,P＞0.05).Anti-MCV and anti-GPI has the highest sensitivity(78.0% and 83.3%),while anti-CCP has the highest specificity(97.1%)and anti-AKA has good specificity(96.1%)and lowest sensitivity(49.4%).When two antibodies were detected together,the sensitivity and specificity of MCV/CCP were highest(92.7% and 96.9%).When RF/GPI/CCP were detected together,the sensitivity and specificity were 90.7% and 96.9%,respectively.When RF/MCv/CCP were detected together,the sensitivity and specificity were 94.0% and 96.9%.Conclusions Anti-MCV and anti-GPI has the hishest sensitivity in laboratory diagnosis of RA,while anti-CCP has the highest specificity and anti-AKA have good specificity and lowest sensitivity.The combination detection can decrease the amount of missed diagnosis caused by single test. The combination detection of RF/GPI/CCP and RF/MCV/CCP will improve sensitivity and specificity for diagnosis to the RA patients.

Objective To explore the management strategy for liver trauma combined with juxla-hepatic venous injury and discuss relating factors leading to postoperative deaths. Methods The clini-cal data of 11 patients with juxtahepatic venous injury were retrospectively analyzed in aspects of prefer-ence of irregular hepatectomy and vein repair.There were 8 males and 3 females,at age range of 22-65 years(mean 33.7 years).Injury causes included traffic injury in 7 patients,fall-from-height injury in 3 and crush injury in 1.Of all,9 patients were combined with other abdominal organ injury and 7 with over one part fractures.All patients showed symptom of shock on admission. Results No patient died dur-ing operation but 3 died after operation.The complications included bleeding in 6 patients,severe infec-tion in 2.liver function failure in 3, acute renaI function failure in 2.bile-1eakage in 4,abdominal ab-scess in 4 and incision infection in 6. Conclusion Low blood pressure in the operation is the main cause for death.It is safe and effective to treat liver trauma combined with juxtahepatic venous injury with irregular hepatectomy and vein repair.

Objective To study the mechanism of high intensity ultrasound (HIU) on COX-2 mRNA expression and apoptosis in breast cancer cell line MDA-MB-231 cells.Methods Human breast cancer cells MDA-MB-231 in vitro were exposed in HIU (50 w/cm2).RT-PCR was performed to detect the level of COX-2 mRNA before and after exposure.The ultrastructural changes in apoptotic cells were examined by transmission electron microscopy.Results The relative level of COX-2 mRNA decreased gradually along with the increase of exposure time and apoptotic bodies in MDA-MB-231 cells considerably increased under electron microscope.When exposure time was increased to 30 seconds,a few cells died.Conclusion HIU promotes apoptosis of breast cancer MDA-MB-231 cells in a COX-2 mRNA depended way.

Objective To establish nude mice model of bone metastasis of breast cancer,and study the best method to evaluate the model.Methods The human breast cancer cell,MDA-MB-231PEGFPN,was injected into left ventricule of nude mice to construct the bone metastasis of breast cancer animal model.Methods of X-ray,whole body optical imaging and pathology were used to evaluate the bone damage after six weeks.Results After six weeks,the result of pathology showed that breast cancer cells had already spread to brain,bone marrow and lung of nude mice.The degree of bone destruction was seen clearly in X-ray,and location of breast cancer cells was observed by whole body optical imaging system.Conclusions The results showed that combined application of X-ray,whole body optical imaging and pathology are the best modalities to evaluate bone metastasis of breast cancer in nude mice.

Objective To study the clinical features and postoperative complications for gastric carcinoma in the patients older than 65 years. Methods From January 2005 to January 2007, 65 elderly gastric carcinoma cases underwent surgical resection, the age related preoperative and postoperative complications were analyzed. Result The incidence of preoperative complications in elderly gastriccarc inoma patients is 83%, compared with younger group of 59%; Preoperatively, 52% elderly cases presented with two or more complications. The incidence of hypertension was the highest (40%), the radical curative rate for the elderly group was 86% as compared with younger group of 93%. The postoperative complications in elderly group was 37%. In elderly cases, postoperative complications were common in those suffering from preoperative complications such as hypertension, diabetes, respiratory diseases, anaemia, hypoalbuminemia. Conclusion The age itself is not a single influential factors indicating postoperative complications. There was no significant difference in the morbidity and mortality between elderly and younger gastric carcinoma cases undergoing a surgery.

Objective To study the inducing factors and clinical characteristics of patients hospitalized for asthma exacerbation in China. Methods Patients hospitalized for asthma exacerbation at 29 hospitals in China were retrospectively recruited during 2013-2014. Results Clinical data of 3 240 asthmatic patients were collected and analyzed including 1 369(42.3%) males and 1 871(57.7%)females. The patients hospitalized for asthma exacerbation counted for 2.95% (6 375/215 955) of all patients hospitalized during the same period. The leading six inducing factors, in sequence, were acute upper respiratory tract infection[42.3%(1 370/3 240)],changes of weather[22.8%(738/3 240)],noxious gas[(4.3% (140/3 240), allergy challenges [3.5%(115/3 240)], strenuous exercise [1.8%(57/3 240)], and air pollution [1.5%(49/3 240)].In older patients,more exacerbations were induced by weather changes,yet less sensitive to allergy challenges. As to middle-aged patients, they were less sensitive to upper respiratory tract infections,however the difference was not statistically significant(P>0.05).In winter more asthma patients were induced by upper respiratory tract infections,while in autumn more patients were induced by weather changes,strenuous exercise and air pollution.In spring and summer more patients were induced by allergy challenges, but the differences failed to achieve statistical significance (P>0.05). In northern cities more patients were induced by upper respiratory infections, whereas in southern cities more by noxious gases. Allergy challenges and air pollution tended to affect more patients in northern cities,but the difference was of no significance (P>0.05). The differences of inducing factors among patients of different gender, with or without a smoking history, and with different exacerbation severity didn't show any statistical significance. The patients with severe and life-threatening exacerbations counted for 20.1%(652/3 240).The percentage of patients older than 60 years was higher in patients with severe or life-threatening exacerbations than in whose with mild or moderate exacerbations,so did the percentage of male patients,of patients with disease duration longer than 10 years, with smoking history, and with a history of hospitalization or emergency department visits due to asthma exacerbation during the last year.Conclusion The acute upper respiratory tract infection ranks top among all the inducing factors. Senility, male gender, long duration of disease, smoking history, and a history of frequent hospital visits might be the risk factors for severe or life-threatening asthma exacerbations.
