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.

[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 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 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.

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.

BACKGROUND:Mesenchymal stem cel transplantation has a certain controversy in the treatment of liver cirrhosis, and its effects on the receptor liver structure and function need further studies.
OBJECTIVE:To study the changes in liver ultrastructure, stereology parameters and liver function indexes of rat models with liver cirrhosis treated by bone marrow mesenchymal stem cel transplantation.
METHODS:Rat models of liver cirrhosis were made using carbon tetrachloride and treated by bone marrow mesenchymal stem cel transplantation. Liver ultrastructure of al the rats were observed by transmission electron microscope, the stereology parameters of the hepatic sinusoid were analyzed by a stereology analysis software, and the serum liver function indexes were detected by a biochemical analyzer.
RESULTS AND CONCLUSION: (1) The hepatic cels in the rat models exhibited acute hypoxia, lots of mitochondria were destroyed, and obvious karyopycnosis and capilarization of the hepatic sinusoid were found. The liver ultrastructure of rats undergoing cel transplantation was improved remarkably, the hepatic cel nucleus was nearly normal, mitochondrial sweling relieved notably and nuclear pore clogging lessened. (2) The number of hepatic sinusoids in the model group was reduced dramaticaly, but the total area and mean diameter of the hepatic sinusoid were enlarged significantly as compared with the cel transplantation and normal groups (P < 0.05). (3) Compared with the model group, the albumin level was significantly increased, but the levels of alanine aminotransferase and direct bilirubin were significantly decreased in the cel transplantation (P < 0.05). In addition, there was no significant difference in the level of aspartate aminotransferase between the model and cel transplantation groups (P > 0.05). These findings indicate that bone marrow mesenchymal stem cel transplantation can improve liver function and structure of rats with liver cirrhosis and lessen pathological changes of hepatic sinusoid, so it is an effective treatment for liver cirrhosis.

Based on previous results of 16S rDNA sequence homologuous and results of physic-biochemical indexes and morphological characteristics in the present work, bacterial strain ge15 isolated from roots of ginseng plants was identified as Stenotrophomonas rhizophila. Confronting incubation results showed that, strain ge15 inhibited the growth of Alternaria panax, Phytophthora cactorum, and Cylindrocapon destructans significantly, and the width of inhibition zone was 13.3, 24.0, 12.0 mm, respectively. Further results showed that the emergence rate and seedling survive rate of ge15 treatment was significantly higher than those of the control, and which was similar to pesticide carbendazol treatment. The ge15 strain has good application potential in ginseng diseases control without contamination.
