[Objective]To study the clinical manifestation,early diagnosis and surgical outcomes of traumatic thoracic disc herniation.[Method]Eleven patients of traumatic thoracic disc herniation were selected from June 2000 to June 2005.There were 8 males and 3 females with an average age of 23.96 years old(ranged,15-38 years old).The average time from traumatism to diagnosis were 4.1 months(range,2 days to 8 months).After early clinical diagnosis,discectomy through posterolateral transpedicular approach were carried out for all 11 patients.[Result]All 11 patients were followed up for an average time of 2.6 years(range,1.1～3.8 years).According to Otani's classification criterion,the results were excellent in 7cases,good in 3 cases,fair in I cases,no poor case and failure case.The excellent and good results were obtained in 90.91% of the patients.[Conclusion]The incidence of traumatic thoracic disc herniation is rather low,and this disease has no representative symptom and sign.Early diagnosis and operative treatment is a very effective guarantee to curative effect for traumatic thoracic disc herniation.

Objective To evaluate the clinical results and the value of usefulness with the operation methods of posterolateral transpedicular approach in treating thoracic disc herniation. Methods Selecting the patient who treated in our hospital from November 1999 to November 2003. In all the 45 patients who suffered from thoracic disc herniation, we had got 43 patients followed up, the following-up times were from 1.2 to 3.5 years. 38 patients were treated with posterolateral unilateral transpedicular approach operation method. There were 26 males and other 19 females. The patients were from 30.5 years old to 67.5 years old, and the mean age was 46.5 years old. The interval between onset of symptoms and operation ranged from 5 to 12 months, and 9 months for average. In this group, 45% patients were involved in T9-10 and T10-11 disc herniation, 4 cases(11%) in T8-9, 4 cases(11%) in T11-12, and 4 cases(11%) in T12L1. All patients underwent X-ray and MR examination. 22 patients underwent myelography, 25 patients underwent CT or CTM examination. Using Otanni scored system to evaluate the clinical results. Selecting the SPSS 11.5 to do the statistics works. Results A perfect result was found in 16 patients, a good result was found in a further 18 patients, and a fair result was found in 2 patients the outcome was unchanged with no effect in 2 cases. No clinical or radiographic features of instability, nervous symptoms and wound infection were found. The clinical satisfaction rate was 89.74%, the results showed that it was a good result of posterolateral entrance operation. Conclusion The posterolateral transpedicular entrance operation shows a good result in treating patients who suffered from thoracic disc herniation.

ObjectiveTo analyze the clinical characteristics of atypical acute myocardial infarction,improve the diagnosis of myocardial infarction. MethodsTo analyze the main clinical characteristics of the patients with atypical acute myocardial infarction in our hospital in the past 3 years ,which compared to the typical acute myocardial infarction. ResultsAtypical acute myocardial infarction includes atypical symptom and atypical ECG, atypical symptoms is more prevail. Compared with typical acute myocardial infarction, the women, elderly people and hypertension patients is more common, fewer anterior myocardial infarction and poorer prognosis ( P ＜ 0.05 ). ConclusionTo improve the understanding of atypical acute myocardial infarction,was benefit of reducing the misdiagnosis and mistreatment of acute myocardial infarction.

Objective To control stem blight disease of Schizonepeta tenuifolia caused by Phytophthora nicotianae.Methods The antagonist effect of 13 Trichoderma strains(including T.viride and T.hamianum)was evaluated upon mycelia growth of P.nicotianae.Trichoderma strains with high antagonistic activities against the pathogen were used to control stem blight of S.tenuifolia in the field.Results Of 13 Trichoderma strains tested,T.viride strain M3 showed maximum mycelia growth inhibition(83.2%)to the pathogen,followed by T.viride strain Tv04-2(78.2%)and then T.harziamum strain ThB(65.0%),in vitro.Fungal cell wall degrading enzymes,protease,and β-1,3-glueanase were analyzed qualitatively and quantitatively in further study.T.viride strains M3,Tv04-2,and T.harzianum strain ThB efficiently against P.nicotianae were used to control stem blight of S.tenuifolia in the field,and T.viride strain M3 showed the best biocontrol potential.Conclusion Trichoderma spp.can be used as alternatives of pesticides to control stem blight,one of the serious soilhome diseases of S.tenuifolia caused by P.nicotianae.However,though T.viride strains Tv04-2 aad T.harzianum strain ThB are also highly against P.nicotianae in vitro,the controlling efficacy of them on stem blight disease is not as excellent as T.viride strains M3 in the field.

ObjectiveTo investigate the relationship between the level of plasma D-dimer(D-D) and hepatic functional reserve status in patients with hepatitis B (HB).Methods77 cases with HB were divided into two groups, hepatic function compensated group and hepatic function decompensated group.Plasma D-D, hepatic functional indexes and PT of all patients were detected.ResultsThe level of D-D in the hepatic function decompensated group was higher than that in the hepatic function compensated group(299.0 ± 498.5) μg/L vs (27.9 ± 34.0) μg/L(t =3.1, P ＜ 0.01).D-D negatively correlated with ALB and PA(r =-0.6,-0.6, all P ＜ 0.01), and positively correlated with TBIL and PT(r = 0.4,0.6, all P ＜ 0.01).ConclusionThe level of plasma D-D related with hepatic functional reserve status,and detecting the level of D-D could be helpful to estimate hepatic functional reserve and prognosis of patients with HB.

Objective To identify certain isoforms involved in the onset of retinal ischemic preconditioning (IPC), the effects of ischemic pretreatment (IP) were observed on level of conventional protein kinase C (cPKC) ?,?Ⅰ、?Ⅱand ? isoform-specific membrane translocation and protein expression in retina of rats. Methods Retinal IP was produced by intra-ocular pressure (IOP) elevation for 5 minutes in anesthetized Wistar rats. Sham operation was similar to IP except the pressure elevation. 10, 20, or 40 minutes and 1, 12, 24, 72 or 168 hours after the procedure, cPKC isoform-specific membrane translocation and protein expression were analyzed using Western-blot. Results cPKC? protein expression significantly increased from 12 h to 168 h. A peak reached at 72 h after IP. cPKC? membrane translocation enhanced during 20 min to 1 hours with a peak at 40 min. cPKC? protein expressionlevels significantly increased from 12 hours to 72 hours. A peak was found at 24 hours after IP. However, there were no significant changes in both membrane translocation of cPKC?, ?Ⅰ、?Ⅱand protein expression of cPKC?Ⅰ, ?Ⅱ in retina of rats following IP.Conclusion The enhanced cPKC? membrane translocation, the increased cPKC? and ? protein expressions might be involved in the onset and sustain of retinal IPC in rats respectively.

Objective To investigate the clinical allocation significance of modified early warning score (MEWS) for emergency department patients.Methods MEWS of 1 069 patients in medical emergency department from August 2011 to March 2013 were recorded and analyzed.The admitted differences of MEWS among in intensive care unit(ICU),general wards and emergency transfer observing patients were compared.Results The MEWS of emergency department patients were different.The deaths and ICU patients together as ICU patients,MEWS ≥ 7 scores the proportion of patients admitted to ICU were significantly higher than those of MEWS 3-6 scores and 0-2 scores [37.8％(14/38) vs.2.1％ (6/289) and 0.1％(1/742)](P＜0.01).Conclusion MEWS provides an objective allocation basis for emergency department patients.

Objective To assess and analyze the current status of clinical guidelines for hypertension in the world by using the Appraisal of Guidelines for Research and Evaluation (AGREE) instrument.Methods The clinical guidelines for hypertension were identified and approved by searching China hownet,WANFANG database,PUBMED database,MEDLINE,Embase and related institutions and authorization web site from 1995 to January 2012,and relevant Web sites of agencies and organizations that produce and/or endorse guidelines.Names of the guidelines,published years and organizations,methodology of development and reference number were descriptively analyzed.AGREE instrument was used to evaluate the qualities of latest edited clinical guidelines for hypertension in countries all over the world.Results Nine guidelines were enrolled.The results showed that the hypertension guidelines scored the highest average of 88.4％ for clarity of presentation and reliability field; for applicability fields,scored an average of 86.1％; the scope and goal field scored an average of 83.8％; participants field scored an average of 71.7％; editorial independence field scored an average of 64.1％ ; rigor of development field scored the lowest average of 62.9％.The overall assessment showed that NICE 2011,Canada 2012,ESC 2009,Australia 2010 editions were the positively recommended guidelines,JNC7,Japan 2009,China Taiwan 2010,China 2010,South Africa 2011 editions were the recommended guidelines (still need to supplement and improve).No recommend or uncertain guide was found.Conclusions The quality of the hypertension guidelines is higher in general,but some common deficiency in the rigor of development and editorial independence in Asian and African guidelines formulated by the states still exists.There still exist certain gaps in evidence-based medical requirement.And the contents and quality are needed for further regulating and enhancing.A set of scientific systemic hypertension clinical guidelines evaluation system should be established.
