Objective:To investigate the expression of insulin-like growth factor binding protein 3 (IGFBP-3) in salivary pleomorphic adenoma(SPA).Methods:The expression of IGFBP-3 protein in 40 cases of SPA(group SPA),40 of normal glandular tissue(group N) and 10 of salivary gland malignant tumor(group CA) was detected by Western blot.The expression of IGFBP-3 mRNA in 50 cases of SPA,50 of salivary gland normal tissue and 10 of CA was detected by qRT-PCR.Results:The expression(A value) of IGFBP-3 protein in group N,SPA and CA was 8.54 ± 3.95,4.78 ± 2.07,3.63 ± 2.27 respectively.The expression ration of IGFBP-3 mRNA of group N vs SPA or CA,P ＜ 0.05;SPA vs CA,P ＞ 0.05 (SPA/N was 0.654 ± 0.387,CA/N:0.452 ± 0.229) respectively,but showed no significance difference between SPA and the CA groups(P ＞ 0.05).Difference of IGFBP-3 mRNA expression was observed with different envelope infiltration of SPA (P ＜ 0.05),no significant difference was observed in different age,gender or relapse groups.Conclusion:IGFBP-3 Low expression of IGFBP-3 in pleomorphic adenomas may reduce the antagonism of IGF-1R,causing the proliferation of tumor cells and promote tumor formation.

Objective To observe the effects of puhnonary rehabilitation on the symptoms and quality of life of persons with chronic obstructive pulmonary disease (COPD).Methods COPD patients were recruited from a hospital and community health centers and given pulmonary rehabilitation in the community.The rehabilitation program included health education and nutrition guidance,medication,breathing exercises,and physical exercise.Each patient was followed up every 4 weeks by telephone.The outcome measures included pulmonary function (FEV1％,FEV1/FVC％),St George's questionnaire (SGRQ),the Medical Research Council scale (MRC),Borg scoring,evaluation of anxiety and depression,the six-minute walk test (6MWT),and an evaluation of nutritional status.All of the patients were observed for one year.Results A total of 85 patients completed the program and were included in the final statistical analysis.There was no difference in FEV1 ％ before and after rehabilitation.Six-minute walking distance improved significantly in statistical terms but the average increase was only from (416.1 ±99.84)m to (437.51 ±116.17)m.The SGRQ scores decreased by an average of 4.8 points after a year of rehabilitation,with significant improvements among the moderately and severely impaired.Incidents of COPD exacerbation also decreased significantly.Patients with a low body mass index had the greatest SGRQ score improvments.Few patients showed depression or anxiety in this research population.Conclusions Pulmonary rehabilitation in the community can improve exercise tolerance and the quality of life for persons with COPD,reducing incidents of acute exacerbation.Patients may benefit from such pulmonary rehabilitation regardless of disease severity.The compliance was good despite the infrequent monitoring.Pulmonary rehabilitation in the community is worthy of more widespread use.

Objective To investigate the clinical characteristics of young rectal carcinomain in order to improve the diagnostic level and therapeutic efficacy at the early stage.Methods Clinical data,including clinical manifestations,misdiagnosis,clinical pathology and prognosis which from 47 cases of young rectal carcinoma were analyzed retrospectively and compared with those from 99 cases of old rectal carcinoma.Results The average course of disease was 6.98 months in young patient group,it was shorter than that in old patient group(9.16 months).The misdiagnosis rate of young group(61.70%) was significantly higher than that in old group(28.28%)(P 0.05).Conclusion Compared with the old patients,advanced stage and poorly differentiated carcinoma are more common in young patients with rectal carcinoma.But the 5-year survival rates of the young and old patients are similar.In addition,T stage and lymph node metastasis are the independent prognostic factors.Therefore,early diagnosis and treatment are crucial to improve the survival rate in young patients with rectal carcinoma.

Objective To observe the effect of contortrostafin on human glioma xengoraft model and explore its mechanism.Method Animal models were established on BALB/c nude mice with subcutaneously transplanted neoplasma of U87 glioma.The nude mice bearing withU87 slioma were devided randomly into two groups,which were treated without drugs or with doses of 40 μg/d.The dimension of xenografts was measured and the living state of nude mice with U87 glioma was observed.The protein expression of microvesel density(MVD),bFGF in each paraff in imbedded xenograft of nude mice bearing with U87 glioma were detected by immunohistochemistry staining.Result Contortrostafin inhibited the growth of xenografts in nude mice with U87 glioma(P＜0.05),and the tumor volume was reduced by 50%.Meanwhile the control group highly expressed bFGF at the level of protein,coupling with increase of MVD.Compared with the dissolvent control group,contortrostatin treated group showed lower expression of bFGF,(P＜0.01)and more decrease in MVD(P＜0.01).Conclusion Contortrostatin diffusa has significant inhibitive effect on human glioma xenograft.

Objective To investigate the efficacy, technical tip, safety and complication prevention of combining Neuroform stents and Guglielmi detachable coils for treating acute ruptured giant intracranial aneurysms. Methods Among 10 cases who were diagnosed with giant intracranial aneurysms,Neuroform stents were released for supporting the neck of aneurysms, then micro-catheters were inserted into aneurysms through lumina of stents and coils were implanted. Results All the operations were completed successfully. There was no complication in these cases. The aneurysms were packed totally in 9 cases and partly in 1 case.Eight postoperative cases were followed up by 6 to 17 months. Neither bleeding nor thrombus was found, and all the patients recovered well. Conclusion Combining Neuroform stents and Guglielmi detachable coils for treating acute ruptured giant intracranial aneurysms is a safe and effective method.

Objective To explore for the methede and effect of endoscopic treatment on biliary leakage and biliary duct damage. Methods All patients with biliary damage such as biliary leakage and biliary duct stricture were treated by endoscopic sphincoterotomy and endoscopic nasobiliary drainage (ENBD) during abdominal cavity drainage ENBD was removd when biliary leakage healed and abdominal cavity drainage ceased for 1～2 weeks were confirmed. Plastic stents were implanted to distend the biliary duct stricture for 2-3 months. Results Twenty-six patients with biliary leakage were cured 3-4 weeks after ENBD. Fourteen out of 17 patients implanted with plastic stent were recovered uneventfully after stent removed, and 4 patients also recovered after installation of double-stents for 3 months, while another case with calculus and stricture of left hepatic duct in spite of implantation of simple-stent suffered repeatedly from biliary tract infection and one case developed hepatic abscess after repeatedly infection for one year before he had the hepatic lobectomy. Conclution Endoscopic therapy is the first choice in treating biliary leakage or secondary duct stricture.

Objective To investigate the effect of augmenter of 1iver regeneration(ALR)on hepatocytes transplanted intraperitoneally in acute hepatic failure(AHF)rats.Methods AHF SD rats were induced by D-gal.The rats were divided into 5 groups randomly:blank control group(only receiving normal saline),transplantation control group(transplanting 2 X 107 hepatocytes from SD rats),ciclosporin A group(CsA group,receiving hepatocytes and CsA 6 days after transplantation),ALRgroup(receiving hepatocytes plus ALR 6 days after transplantation),ALR control group(only receiving ALR 6 days after transplantation).All drugs and cells were intraperitoneally injected.There was a observation period of 14 days after transplantation.The survival rate of receptors and transplanted hepatocytes was observed.The expression levels of CD4,CD8 and CD68 in abdominal cells,the levels of IL-1β and TNF-a in serum and douche of peritoneal cavity were detected.Results The 2-week SuFvival rate in blank control group,transplantation control group,CsA group,ALR group and ALR control group was 0,46.7%,20%,66.7%and 14.3%respectively.Survival rate in AI.R group was higher than in blank control group(P=0.001).Serum levels of d1-2 TNF-a in ALR group was all lower than in blank and transplantation control groups(P＜(0.01).Serum levels of d1-2 IL-18 in ALR group were lower than in transplantation control group.Ascitic levels of d1-2 TNF-a and IL-1β in transplantation control group were higher than in other groups(P＜0.05,P＜0.01).The serum levels of TNF-a and IL-1β in all survival groups were similar tO normal levels on the 14th day after transplantation.The positive expression rate of d1-2 CD68 in grafts of ALR group was(0.5±0.3)%.The positive expression rate of CD68 in grafts of ALR group was obviously lower than in transplantation control group and CsA groups(P＜0.01).The expression of d1-2 CD68,CD4 and CD8 in ALR group was respectively(1.3±1.2)%,(0.1±0.3)%and(0.2±0.1)%,all obviously lower than in transplantation control group(P＜0.01,P＜0.01,P＜0.05).Assembled conglobate hepatocyte noduses were observed in abdominal cavity in rats receiving hepatocytes transplantation during first to third day after transplantation.The number of survival grafts in ALR group was more than that in transplantation control group and CsA group,and infihrated inflammatory cells were less.On the 14th day posttransplantation.small amounts of normal hepatocytes in grafts were observed only in ALR group.Conclusion After HcT plus ALR intraperitoneally,the survival rate of AHF rats was increased.ALR improved survivorship of transplanted hepatocytes in short term.

OBJECTIVE To investigate the protective effect of Sika deer velvet antler protein (SVPr) against renal toxicity in mice and its mechanism.METHODS Forty ICR mice were randomly divided into 5 groups:normal control group (ig distilled water),model group (ig distilled water for 7 d,on the 7th day,ip cisplatin 25 mg·kg-1 to establish the model,afterwards ig distilled water for 3 d) and SVPr 5,10 and 20 mg· kg-1 groups (ig SVPr for 7 d,cisplatin 25 mg· kg-1 was provided 2 h after the last administration,then ig SVPr for 3 d).Testing kits were adopted for the measurement of renal indexes in mice,such as blood urea nitrogen (BUN) and serum creatinine (SCr);oxidative stress indictors of super oxide dismutase (SOD),catalase (CAT),glutathione (GSH) and malondialdehyde (MDA);inflammation indictor levels of tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6).Caspase 3,Bax and Bcl-2 were detected via Western blotting,and renal pathological changes were observed by HE staining.RESULTS SVPr (5,10 and 20 mg·kg-1) significantly reduced the levels of SCr,BUN,MDA,TNF-α and IL-6,and the expressions of caspase 3 and Bax (P＜0.05),but increased the activities of SOD,CAT and GSH,and the expression of Bcl-2 (P＜0.05).The renal pathological changes were improved.CONCLUSION SVPr can reduce renal toxicity induced by cisplatin in mice,and the mechanism is probably related to inhibiting oxidative stress or inflammatory reaction and improving cell apoptosis.

Objective To assess the efficacy of stone fragmentation and clearance of this new intracorporeal ultrasound lithotripter (CQS-01) compared with currently available ultrasound units (EMS-Ⅲ/Ⅳ).Methods Twenty phantom stones composed of dental gypsum were randomly divided into four groups,and CQS-01 ultrasound lithotripter (70％ power and 70％ duty factor),EMS-Ⅲ ultrasound lithotripter (70％ power and 70％ duty factor),EMS-Ⅳ ultrasound lithotripter (type A,70％ power and 70％ duty factor) and EMS-Ⅳ ultrasound lithotripter (type B,70％ power and 100％ duty factor) were used to fragment and removepbantom stones.The mean stone breakdown time and fragment removal time and stone fragmental sizes for the standard ultrasound devices were compared to determine the completeness and efficiency of stone fragmentation and removal.Results The average time for stone breakdown was 7.4 ± 1.9 s,9.4 ± 1.6 s,82.2 ± 12.6 s and 51.4 ± 18.7 s,respectively.There was no significant difference between CQS-01 and EMS-Ⅲ (P ＞ 0.05),but there was significant difference between CQS-01 and EMS-Ⅳ (A or B) (P ＜ 0.001).The average time for stone clearance using the ultrasound devices was 387.8 ± 68.0 s,41 1.6 ± 57.6 s,568.0 ± 119.1 s and 383.6 ± 75.6 s,respectively.In addition,the average size of the largest fragments removed was the same among the groups (＜ 3 mm).Conclusion The ultrasound capabilities in a newly developed lithotriter (CQS-01) exhibited the same ability to fragment and clear phantom stones compared with standard ultrasound devices.
