Aim To observe the effect of pyrimidine dithiocarbamate (PDTC) on the variance of disc morphology and the expressions of TNF-α, MMP-9 in the cervical disc in cervical dynamic equilibrium rat models, and to investigate the roles of PDTC in the process of intervertebral disc degeneration and the mechanism involved.Methods Fifty-four SD rats were divided into three groups randomly, then the dynamic equilibrium rat model was established by cutting the nuchal superficial and deep muscle of the rats.The dynamic equilibrium rats with PDTC solution intraperitoneal injection after operations were defined as PDTC group (group A), the models with saline intraperitoneal injection after operations as saline group (group B), the rats of fake operation with saline intraperitoneal injection as blank group (group C), and the animals were sacrificed in batches 10 weeks, 12 weeks, 16 weeks respectively after operation.The C5, C6 vertebrae and C5/6 discs were harvested, and the disc morphology was observed.TNF-α, MMP-9 mRNA expressions were detected by q-PCR and protein expression was observed by Western blot.Results Compared with the saline group, the morphology of disc in PDTC group was destructed slightly and fiber ring arranged orderly.TNF-α, MMP-9 gene and protein expressions had no obvious changes (P>0.05) in blank group (group C) at each time point.The expressions of IL-6, MMP-9 mRNA increased with time in group B, but the amount increased fast firstly, and slow lately, reaching peak in 12 weeks.The expression of TNF-α, MMP-9 protein became steady in group B from 10 weeks compared with other time points(P>0.05).TNF-α, MMP-9 genes and proteins expression decreased obviously in PDTC group (group A) compared with saline group (group B) (P<0.01) at each time point, but higher than blank group C(P<0.01) at each time point.Conclusions TNF-α and MMP-9 are important inflammatory factors involved in rat cervical disc degeneration, PDTC relieves the degeneration of rat cervical disc by reducing the expression of TNF-α and MMP-9 via disturbing the NF-κB signal pathway probably, and PDTC may become potential medicine for disc degeneration.

Objective The clinical manifestations of Parkinson''s disease (PD) are divided into non-motor symptoms and motor symptoms.Constipation is one of the common symptoms of non-motor symptoms of the disease.Constipation symptoms in PD generally occur earlier for 5~20 years, while drug treatment for PD constipation can lead to gastrointestinal damage.This study investigated the improvement in the treatment of anorectal dynamics and constipation symptoms in Parkinson''s disease by oral mosapride and press-needle therapy of Shu-Mu point.Methods 60 patients diagnosed as constipation of Parkinson''s disease were randomly divided into control group and treatment group, 30 cases in each group;patients in the control group were treated with oral mosapride tablets, while patients in the treatment group received press-needle therapy, three times per week.The observation course in both groups last for three months and follow-up visits were conducted before and after the course.Efficacy evaluation, PAC-QOL scale and anorectal dynamic examination were applied in the follow-up visit.Results The efficiency of treatment group was 81.7%, significantly higher than control group (70%), representing significant difference between the two groups (P<0.05).Both the methods could improve the PAC-QOL scale, and significant difference was found in comparison to that before the treatment(P<0.01), while no statistical significance was found between treatment group and control group after treatment(P>0.05).As to the anorectal dynamics, significant difference was found before and after the treatment in both groups (P<0.05, P<0.01), while no statistical significance were found between the two groups after treatment(P>0.05).Conclusion Both oral mosapride and press-needle can improve the quality of life and anorectal dynamics for PD patients, representing no significant difference.However, compared with mosapride, the overall efficacy of press-needle is better in improving the symptoms of constipation in PD, featuring more convenience, higher safety, less pain and no side effect, and it is worthy of clinical application.

The dissolution of Panacis Quinquefolii Radix ultrafine granular powder and common powder, traditional pieces in water and simulated gastric juice in vitro was compared, and the effect of particles size of Panacis Quinquefolii Radix on the dissolution was studied. HPLC method was used for determination of five ginsenosides including Rg1, Re, Rb1, Rc and Rd from ultrafine granular powder and common powder, traditional pieces of Panacis Quinquefolii Radix at different points in time, furthermore, the dissolution curves of Panacis Quinquefolii Radix ultrafine granular powder and common powder, traditional pieces were obtained. The dissolution characteristics of the three Panacis Quinquefolii Radix forms were also compared in this study. According to the results, the dissolution rates of ginsenosides from ultrafine granular powder exceeded 90% of the total content with 5 min, significantly higher than that of the other two forms in water in vitro. At the same time, the dissolved amount of the ultrafine granular powder was fourteen percent higher than that of the traditional pieces and eight percent higher than that of the common powder. Under the condition of simulated gastric juice in vitro, the dissolution rates of ginsenosides from ultrafine granular powder were little lower than that of the other two, but the maximum dissolved amount of the former was fourteen percent higher than that of the common powder and five percent higher than that of the extracts. Therefore the conclusion is that micronization of Panacis Quinquefolii Radix contributed to dissolution of effective components.

OBJECTIVETo evaluate the possibility of applying oligonucleotide microarrays for detection of the fusion genes in childhood acute lymphoblastic leukemia (ALL).

METHODSTo detect five types of fusion genes emerging frequently in childhood ALL including TEL/AML1, E2A/PBX1, BCR/ABLp190, BCR/ABLp210, MLL/AF4, probes were designed, synthesized and spotted on the chemical-material-coated-glass plates in array. The total RNAs were extracted from patients' bone marrow or peripheral blood cells at the beginning of diagnosis, analyzed by multiplex nested reverse-transcription-polymerase chain reaction (RT-PCR), and labeled by fluorescein. The products of RT-PCR were hybridized with microarray in order to detect specific types of fusion genes in leukemia cells.

RESULTSDistinctive hybridization signals were obtained for internal positive control and specific types of fusion genes. TEL/AML1 gene was found positive in 2 of the 36 cases, E2A/PBX1 gene in 3, BCR/ABLp190 gene in 2, BCR/ ABLp210 gene in one, and MLL/ AF4 gene in one. The results of the microarray and RT-PCR were consistent.

CONCLUSIONThe microarray-based assay could screen 5 types of chromosome structural aberrations and the splice variants at the same time. It can provide reliable and helpful information for patient stratification, evaluation of therapeutic effects and prediction of prognosis in childhood ALL, although there are both advantages and disadvantages in applying this new method.

OBJECTIVETo explore selection and efficacy assessment for membranous urethral trauma caused by pelvic fracture.

METHODSFrom June 2000 to August 2010, 72 patients with membranous urethral trauma caused by pelvic fracture were selected. There were 46 males and 26 females,ranging age from 26 to 62 years (averaged 35.2 years). The time from injury to hospitalization time was 1 to 3 hours. According to Tile pelvic fracture classification, there were 8 patients with type A, 45 patients with type B, 19 patients with type C. Thirty of the 35 patients with partial rupture of posterior urethral were treated by catheterization,5 patients treated by rupture anastomosis on the stage I combined with cystostomy; 25 of the 37 patients with complete rupture of posterior urethra were treated by early realignment, and 12 patients were treated by cystostomy. Urinary incontinence, impotence and urethrostenosis were evaluated.

RESULTSAll patients were followed up for 5 to 10 years (mean 7.7 years). Incidence of urethrostenosis, impotence and urinary incontinence in patients treated by cystostomy were significantly higher than rupture anastomosis on the stage I and early realignment (P < 0.05); while incidence in patients treated by catheterization was significantly lower than other groups (P < 0.05).

CONCLUSIONFor patients with partial rupture of posterior urethral, catheterization and rupture anastomosis on the stage I are preferred methods; while patients with complete rupture of posterior urethra, early realignment is a preferred method with advantages of simple operation and less complications.

OBJECTIVETo investigate the relationship between C7673T polymorphism of apolipoprotein B (apoB) and cerebral hemorrhage with family history (CHFH) in Chinese Han in Changsha, Hunan province.

METHODSFifteen families of CHFH and 93 sporadic cerebral hemorrhage patients and 100 normal controls were collected. The C7673T polymorphism of apoB was analyzed by PCR-restriction fragment length polymorphism and direct DNA sequencing. The triglyceride(TG), total cholesterol(TC), high density lipoprotein-cholesterol (HDL-C) and low density lipoprotein-cholesterol(LDL-C) levels were examined by oxidase method. The serum level of lipoprotein (a) was determined by immune method.

RESULTS(1)The allele T frequencies of apoB C7673T polymorphism in cerebral hemorrhage patients with family history, first-degree relatives, second-degree relatives, third-degree relatives, the sporadic cerebral hemorrhage patients and the control group were 0.176, 0.136, 0.058, 0.048, 0.081 and 0.040, respectively. (2) The allele T frequencies of apoB C7673T polymorphism in CHFH patients and their first-degree relatives were significantly higher than that of the control group (P< 0.01, P< 0.01), while there was no significant difference among second-degree relatives, third-degree relatives and control group (P> 0.05). And the allele T frequency of apoB C7673T in CHFH patients was significantly higher than that of sporadic cerebral hemorrhage patients (P< 0.05). (3)In CHFH patients and sporadic cerebral hemorrhage group, the levels of TC and LDL-C of the TC genotype were significantly higher than those of the CC genotype, while the level of HDL-C in the TC genotype was significantly lower than that of the CC geneotype (P< 0.05).

CONCLUSION(1)The allele T of apoB C7673T polymorphism may be related to cerebral hemorrhage with family history. (2) The allele T of apoB C7673T polymorphism may increase the susceptibility of cerebral hemorrhage by changing blood lipid levels.

OBJECTIVE: To explore KM3 multiple myeloma (MM) cell line specific cytotoxic T lymphocyte (CTL) response in vitro mediated by autologous dendritic cells (DCs) aroused by KM3 cells' lysates and acid-eluted peptides. METHODS: Monocytes were isolated from the peripheral blood of healthy individuals and MM patients, and were cultured in serum medium with IL-4, GM-CSF, and TNF-alpha to generate DCs. These DCs were pulsed by KM3 cells' lysates or the acid-eluted peptides, then incubated with autologous T lymphocytes for 3 days to induce KM3 cell antigen specific CTL. MTT assay was performed to examine the specific KM3 cells' lysing ability of CTL. RESULTS: DCs were generated in peripheral blood monocytes cultured in the serum medium containing GM-CSF, IL-4, and TNF-alpha. Autologous T lymphocytes induced by IL-2 and DCs pulsed with KM3 cells' lysates or the acid-eluted peptides showed strong killing effect on KM3 cells. CONCLUSION The DCs pulsed by KM3 cells' lysates or the acid-eluted peptides incubated with autologous T lymphocytes can induce KM3 cell antigen specific CTL.
