In order to observe the changes of myotension in the paralyzed limbs after subcutaneous injection(S.C)of capsaicin,we observed the changes of the spontaneous Electromyography(EMG)recorded in the quadriceps femoris before and after T-5 level spinal transection and found that the amplitude of EMG kept a low level in normal rats but increased progressively after operation.After treating the animals with capsaicin 200mg/kg(S.C)in three consecutive days,we found a much lower spontaneous EMG and a much higher pain threshold than that of the controls.Radioimmunnoassay detected that the content of SP in spinal dorsal horn was reduced by 38.4%,the general condition did not severely changed during the experiment.The results indicate that SP in the spinal dorsal horn participates in the regulation of myotension,and it is suggested that subcutancous injection of capsaicin may be one effective treatment to reduce the hypermyotension in the paralyzed limbs.

ObjectiveTo sum up the clinical experience in recent 10 years in our organ transplantation center. Methods We retrospectively reviewed clinical data of 120 patients receiving liver transplantation from April 1993 to October 2002. The patients′ clinical characteristics, surgical techniques, complications and survival rates were compared between the periods of 1993～1997 (phase Ⅰ), 1999 (phase Ⅱ), and 2000～2002 (phase Ⅲ). ResultsMalignant liver diseases were major indications for liver transplantation in phase Ⅰ (100%) and Ⅱ (53%), and phase Ⅲ (34%), respectively. The survival rate of recipients with benign liver diseases in phase Ⅲ significantly improved with the 3-month, 6-month and 1-year survival rates of 86%, 85% and 83.1%, respectively. For patients with malignant liver diseases, the 3-month, 6-month and 1-year survival rates were 87%, 81% and 46%, respectively. The recurrence of hepatitis B was 24% in 12 months after transplantation. The incidence of postransplantation vascular complications decreased significantly (from 29% in phase Ⅰ and Ⅱ to 4.9% in phase Ⅲ).Biliary complications remained one of the major problems for long-term survival. No veno-venous bypass was applied in phase Ⅲ. ConclusionStrict selection of candidate recipients, technical refinement, appropriate management of vascular and biliary complications, and prevention of recurrence of hepatitis B and malignant liver diseases are important for long-term survival.

In older to study the interrelationship between laryngeal carcinoma and human papillomavirus (HPV). The distribution and expression of genome types of HPV in laryngeal carcinoma were investigated. HPV DNA of 160 cases of fresh tissue samples with different lesions of the larynx was detected by applying consensus primers and multiple primers of polymerase chain reaction (PCR) . The consensus primers used were able to detect 9 types of HPVs DNAs such as HPV6, 11, 16, 18, 31, 33, 34, 42 and 58. The results turned out to be as follows: The rate of positive cases with HPV infection was 49.3% (35/71) for the group of laryneal carcinoma, 22.7% (5/22) for the group of neck metastatic lymphnode, 11.8% (2/17) for precarcinomous lesions and 6.7% (2/30 ) for the group of vocal cord polypus, 20 case of normal laryngeal tissue adjacent to the carcinoma was HPV DNA negative. The results demonstrated that the occurrence and development of laryngeal carcinoma were closely related to HPV infection.

BACKGROUND: Injury of axillary nerve leads to the inability of abduction in the upper limb which needs surgery treatment. However, which way of operative approach is more preferable is still uncertain. Whether one-stage posterior operation of nerve transfer can achieve better effects remains unclear, the choice of approach method is an argument.OBJECTIVE: To explore the therapeutic effect of the transposition operation of the branch to long head of triceps branchii to recover the anterior branch of axillary nerve that can restore the function of deltoid muscle and refrain from the deprivation of function to extend elbow.METHODS: A total of 13 cases with axillary nerve injury without any recovery sign admitted at the Department of Hand Surgery, China-Japan Union Hospital of Jilin University were selected, including 11 males and 2 females, aged 18-55 years, mean aged 28.4 years; Under 10-times operating microscope, the anterior branch of axillary nerve was chosen to coincide the branch to long head of triceps branchii in use of 11 -0 atraumatic nylon in posterior approach. The standard issued by the Hand Surgery Society of Chinese Medical Association was adopted to assess the upper limb function postoperatively.RESULTS AND CONCLUSION: All patients were followed-up for 6-53 months with an average of 21 months. All incisions after surgery gain primary healing. The function of shoulder abduction had recovered in some degree. Among of total, 7 cases had deltoid strength of M4 or even more; 4 cases had deltoid strength of M3; one had M2 and one had M1. The effective rate was 92%, and excellent rate was 85%. There was no impact on the extension of elbow in all cases. It was a reliable and convenient technique to recover shoulder abduction with the branch to long head of triceps brachii from radial nerve in restoration of the function of deltoid muscle. It was beneficial to the restoration of axillary nerve with partially injured brachial plexus, and severe quadril.

AIM To establish a high performance liquid chromatographic method (HPLC) to determine the concentration of valsartan in human plasma. METHODS Separation was achieved on the lichrospher C 18 column. The mobile phaseconsisted of pH 3 1 phosphate buffer acetonitrile (53∶47, V/V) was used at a flow rate of 1 0 ml?min -1 . The fluorimetric excitation and emission wavelengths were set at 265 nm and 378 nm, respectively. The plasma samples were acidified with HCl, extracted with ethyl acetate. Separate the organic phase, remove the solvent and then residue was dissolved in mobile phase. RESULTS The retention time of valsartan was 12 5 min. The calibration curves were linear in the range of 5 9～ 2 360 ?g?L -1 . The precision values (RSD) of intra day and inter day were determined to be 2 83%～7 07% and 1 57%～8 41% respectively. The absolute recovery rate were 80 30%?5 13%. The method was applied to determine the peak and valley concentrations in plasma of the hypertensive treated with 80mg valsartan per day. CONCLUSION The assay was sensitive and simple. It is suitable for the study of the pharmacokinetics of valsartan.

AIM: To evaluate the effects of NS-398, a cyclooxygenase-2(COX-2) inhibitor, on the proliferation and apoptosis in HepG2 cells. METHODS: The effects of NS-398 on the proliferation of HepG2 cells was evaluated by MTT. DNA fragmentation gel analysis was used to analyze the apoptotic cells; DNA ploidy and apoptotic cell percentage were examined by flow cytometry. Furthermore, the expression of COX-2 and Bcl-2 mRNA was identified by competitive RT-PCR. RESULTS: NS-398 inhibited cell proliferation and induced apoptosis in HepG2 in a concentration-dependent manner. DNA ploidy analysis showed that S phase cells were significantly decreased with NS-398 concentration increasing. The quiescent G_0/G_1 phase was accumulated with decreasing of Bcl-2 mRNA. Whereas NS-398 had no effect on the expression of COX-2 mRNA, no correlations were found between COX-2 mRNA and the HepG2 cell proliferation and apoptosis induced by NS-398 (r=0.056 and r=0.119, respectively). CONCLUSION: NS-398 significantly inhibits the proliferation and induces apoptosis in HepG2. Mechanisms may be involved in accumulation of quiescent G_0/G_1 phase and decrease in Bcl-2 mRNA expression, but independent to COX-2 mRNA expression. [

AIM: To investigate the possible role of nuclear transcription factor kappa B (NF-?B), Bcl-2, Bax and caspase-3 in etodolac-induced apoptosis of liver tumor SMMC7721 cell line. METHODS: Cell apoptosis was determined by flow cytometry analysis with PI staining and DNA laddering. Expression of Bcl-2 and Bax protein was measured by Western blotting.
