The rates of FIQ less than normal IQ were 65.8 %, impaired intelligence 28.9 % in patient group. 2.The latencies and the amplitudes of P 300 were significantly delayed and decreased respectively in both patient groups (P

Lymph node metastasis is one of the main methods of metastasis and it affects the the prognosis of patients with gastric cancer. It is reported that the rate of tumor recurrence in patients with tumor-negative lymph nodes detected by routine pathology is approximately 25%, which is a factor that affects the survival. It is reported that the phenomenon associates with lymph nodes micrometastasis closely. The article will tou-ch the latest development on micrometsstasis.

Clinical medical postgraduate education is an important part of higher education in China.We analyzed the current status,major problems existed,direction of the reform and the prospect in the training system.Unifying cultivation criterion,diversifying form of academic degree system,making selection standard strict for advisors and decreasing the proportion of research work for doctors were considered as the effective measures to address these issues.

Objective To evaluate the efficacy and prognostic factors of combined medical thera-py with amitriptyline, cimetidine and intravesical resiniferatoxin post-hydrodistention for patients with painful bladder syndrome/interstitial cystitis (PBS/IC). Methods Twenty-nine patients with PBS/ IC according to NIDDK criteria were enrolled. There were 6 males and 23 females with average age of 52±14 years and average duration of symptoms of 3.7±1.9 years before diagnosis. The patients were divided into 2 groups. Non-concomitant disease group included 10 cases without concomitant disease and 7 cases with unrelated diseases such as hypertension and diabetes mellitus. Concomitant disease group included 5 cases with history of bladder neck incision, 3 cases with history of transurethral re-section of the prostate, 2 cases with history of gynecologic disease and 2 cases with history of gyneco-logic operation. Patients of concomitant disease group still had the painful bladder syndrome after 3 months when the primary disease had been cured. All patients were treated with amitriptyline (25 mg twice a day), cimetidine (800 mg per day) and intravesical resiniferatoxin (1-2 times) post-hydrodis-tention. The primary assessment index was O'Leary-Sant score. The secondary assessment index was pelvic pain score, mean voiding times per day and mean volume of each micturating. The data of pa-tients before treatment and after follow-up≥9 months were collected to evaluate the efficacy and prog-nostic factors of the combined treatment. Results The mean follow-up for all patients was 9.2±6.0 months. Patients were followed up at month 1 and month 6 after discharge. Then, patients would be followed up at each 6 months interval. The overall remission rate was 65.5% (19/29). Complete re-mission rate was 41.4% (12/29). Partial remission was 24. 1% (7/29). Non-remission rate was 34.5% (10/29). For all patients, the pre-treatment mean voiding times per day were 29±15, voiding volume each time was 64±36 ml, average O'Leary Sant score was 23. 8±4.8, and they were signifi-cantly improved post-treatment (17±12 times, 172±108 ml, 13. 3±10.4, respectively, P<0.001). O' Leary-Sant score of concomitant disease group was lower than that of non-concomitant disease group (21.5±4.7 vs 25.4±4.3, P=0.030). However, complete remission (8.3%, 1/12) of con-comitant disease group was lower than that(64. 7%, 11/17) of non-concomitant disease group (P= 0. 003). In independent variables of patients age, sex, duration of symptom, O'Leary Sant score pre-treatment, and whether or not with concomitant disease, according to the results of Logistic Regres-sion, patients with concomitant disease would have poor prognosis (P-0.008, partial regression coef-ficient was -3. 899, OR was 0. 020). Conclusions Treating PBS/IC patients with amitriptyline, ci-metidine and intravesical resiniferatoxin post-hydrodistention is effective. However, concomitant dis-eases such as gynecologic disease or urethra operation history can impair the effectiveness of these treatment.

ObjectiveTo evaluate the efficacy and safety of Sirolimus (SRL) in immunosuppression following liver transplantation. Methods SRL was applied in 21 patients totally.Indication for adoption was Tac-related nephrotoxicity (4/21), suspiciously Tac-related hepatoxicity (8/21), Tac overdose (3/21), renal insufficiency pre-operation (2/21), or cancer (4/21). Median follow-up was 25. 4 months. Results SRL provided an adequate prophylaxis against rejection in all study patients, with one case of acute rejection. Sirolimus was Withdrawn in 2 cases due to its sideeffect. Tat-induced hepatoxicity in 6 cases and nephrotoxicity in 3 cases were relieved significantly.Conclusions SRL given alone appears to be an effective primary immunosuppressant regimen fororthotopic liver transplantation patients. Early conversion contributes to significant improvement of Tac-related hepatoxicity and nephrotoxicity.

Objective To study the function and mechanism of GIT1(G protein coupled receptor kinase interacting protein 1)in osteoblast migration.Methods GIT1 and ERK1/2(Extracellular Signal-regulated ki- nase 1/2)were detected in mice primary osteoblasts.The localizations of GIT1 and ERK1/2 were determined by immunofluorescence stain with or without PDGF(platelet-derived grnwth factor)stimulation.The association of GIT1 anti ERK1/2 was analyzed by co-immunoprecipitation and western blot.After stimulation,the co-localization of GIT1 and pERK1/2 in osteoblasts was detected by double-immunnfluorescence stain.The pERK1/2 localization was detected by immunofluorescence stain after GIT1RNAh adenovirus infection of osteoblasts.The role of this associa- tion was determined by wound healing assay.Results The co-immunoprecipitation results showed that GIT1 in- teracted with ERK1/2 in osteoblasts induced by PDGF and this association occurred in focal adhesions.GIT1 RNAh adenovirus significantly inhibited the pERK1/2 translocation to focal adhesions and osteoblast migration induced by PDGF.Conclusion GIT1 associates with ERK1/2 in osteoblasts,which is required for pERK1/2 translocation to focal adhesions and osteoblast migration.

Objective To observe the effects of low frequency transcranial magnetic stimulation (LF-TMS) on the electroencephalogram (EEG),expression of NPY in hippocampus in pilocarpine (PLO)-induced epileptic rats. Methods Forty male Sprague-Dawley rats (240-260 g) were used to establish a model of epilepsy by in- tradominal injection of pilocarpine,and then randomized into 2 groups:a control group and an intervention group. The control group was treated by sham LF-TMS,while the intervention group was treated by LF-TMS once daily for 7 days.Ⅰgroup simply celiac inject pilocarpine.Ⅱgroup celiac inject PLO after LF-TMS.The EEG was recorded in both groups and the checked pathology.Pathological item include HE staining,NPY immunohisto chemical staining. Results The latency for seizure attack was significantly lengthened,while the frequency of seizure attack and times of major seizure attack were significantly decreased in the intervention group.The HE staining revealed significant de- generation and necrosis of neurons in the hippocampus,especially in the CA3 region,in rats in the control group. The pathologic changes were significantly less severe in the intervention,Immunohistochemical staining showed a sig- nificantly higher expression of NPY in the hippocampus as compared with the intervention group. Conclusion U- sing the PLO-induced epilepsy model,LF-TMS could not only postpone the generation of kindling but also inhibit the progress of epilepsy.The increased NPY expression in the hippocampusin the intervention group implied a close rela- tionship between NPY and epilepsy attack.

Objective To investigate the changes of 4 histamine receptors (H1R, H2R, H2R and H4 R)in interstitial cystitis on animal experimental models. Methods Thirty female SD rats (250-300 g) were randomly divided into 2 groups as follows: 20 in experimental group and 10 in control group. The experimental group was filled with protamine sulfate+ potassium chloride to create interstitial cystitis model, the control group was sacrificed directly. At the end of the experiment, the bladders of all these SD rats were studied by the immunohistochemistry staining and the value of their mean absorbance (-A) was calculated by IPP4.5 image analysis software. The SPSS 11.5 was used to analyze the differences between the groups. Results Four kinds of histamine receptors mainly expressed in the bladder epithelium. In the experimental group, the (-A) of H1 R was 0. 054±0.031, the of H2R was 0.032±0.021, the (-A) of H3R was 0.047±0.033 and the (-A) of H4R was 0. 149±0. 191,respectively. In the control group, the A of H1R was 0. 017±0. 011, the (-A) of H2R was 0. 018±0. 015, the (-A) of H3R was 0. 014±0. 011, the (-A) of H4R was 0. 060±0.039, respectively. In contrast,the A of H1 R, H2 R and H3R in experimental group was increased significantly(P＜0.05); there was no significant change in (-A) of H4R expression(P＞0.05). Conclusions H1, H2 and H3 receptors in rat model interstitial cystitis bladder epithelium have increased and it indicates H1 R, H2R and H3R may be related to interstitial cystitis. H3 R may be a new treatment target of interstitial cystitis.
