ABSTRACT
ObjectiveTo explore the risk factors for upper gastrointestinal bleeding after craniocerebral trauma.MethodsTo retrospectively summarize the clinical features of 80 cases with craniocerebral truma and to analyze the risk factors for upper gastrointestinal bleeding.Results Upper gastrointestinal bleeding was present in 39 of the 80 cases(48.8％) .Twenty-one of the 39 cases with gastrointestinal bleeding died(53.8％)In the patients without gastrointestinal bleeding, 5 cases died (19.2％) .Among the factors affecting the gastrointestinal bleeding after craniocerebral trauma, Glasgow Coma Scale(GCS) score, septicemia, decerebration,hypotention, metabolic acidosis and hyperglucose were closely related risk factors(x2 = 13.96;x2 = 27.43;x2 =46.28 ;x2 = 27.33 ;x2 = 11.88 ;x2 =5.71 ,P ＜0.05 or P ＜0.01).ConclusionProphylaxis against related risk factors could reduce the incidence of gastrointestinal bleeding, improve the prognosis and decrease the mortality of craniocerebral trauma.
ABSTRACT
Objective To investigate the possible effects of COL8A1 on the proliferation, invasion and drug sensitivity of murine hepatocarcinoma cell line Hca-F, we used an RNA interference (RNAi) approach to silence COL8A1 expression. Methods The expression levels of COL8A1 in HcaF/siRNA cells were assessed by RT-PCR and Western blot. The inhibitory effect of RNAi on Hca-F cell invasion in vitro was demonstrated by ECM invasion assay. The in vitro proliferative ability and drug sensitivity of COL8A1-deficient cells were determined by MTT assay. Results The expression of COL8A1 was significantly reduced in COL8A1/siRNA cells after 30h transfection, compared with both the RNAi control and the Hca-F cells. The reduced COL8A1 expression also attenuated the proliferative, invasive ability, as well as increased drug sensitivity of Hca-F/siRNA cells. Conclusion Our current results indicate that the expression of COL8A1 functionally mediates tumor cell proliferation, invasion, and drug sensitivity, and is a potential target for therapeutic anti-cancer drugs.
ABSTRACT
Objective To investigate the toxicity attenuation and efficacy potentiation effects of Shiquan Dabu Tang (SDT) on high dose chemotherapy in T739 mice with bladder carcinoma. Methods Mouse bladder carcinoma tissue was inoculated subcutaneously into T739 mice to establish tumor-beating mice model. The tumor-bearing mice were randomly divided into a CTX group (100, 200, 400 mg/Kg respectively), a SDT group (high or low dose respectively), a high-dose SDT combined with 200 mg/Kg CTX group and a control group. The body weight, diameter of tumor nodules and complete blood count were observed subsequently. Results Different doses of SDT could effectively inhibit tumor growth in mice. SDT + CTX treatment significantly prolonged the survival time of mice by 49.4±23.3 days (P<0.01, 0.05, 0.01), compared with high dose SDT treatment (17.4±5.77) days, 200 mg/kg CTX treatment (23±14.02) days and control group (11.75±2.06) days respectively. The peripheral platelet count increased more significantly in mice treated with SDT within a week as compared to mice without SDT treatment (P<0.05). The peripheral RBC count and liB concentration increased more significantly in mice treated with SDT for 2 weeks as compared to mice without SDT treatment (P<0.05). Conclusions SDT could enhance the anti-tumor effects of high dose CTX on tumor-bearing mice and reduce toxicity in its peripheral red blood cells. The results showed that SDT combined with high dose of CTX chemotherapy had toxicity attenuation and efficacy potentiation effects in tumor-beating T739 mice.
ABSTRACT
@#ObjectiveTo study the therapeutic effect and mechanisms of nourishing Piyin Remedy (nPR) on experimental rat spinal cord injury.MethodsThirty-two healthy SD rats were divided into 2 equal groups randomly: nPR group and injured group. Animal model of incomplete injury of spinal cord was made by Allen's equipment on rat's T8—T9 segment. The spinal nerve function,SEP,retrograde and label technique of horse radish peroxidase,gross observation,histological and morphometric analysis were taken as the observed indices.ResultsThe value of observed indices of nPR group were improved evidently compared with injured group.ConclusionNourishing Piyin Remede can hold back the secondary spinal cord injury and accelerate the recovery of spinal nerve function.

Objective To detect the Telomerase inhibitor-antisense phosphorothiate oligonucleotide (asONS) effect on telomerase activity of human bladder tumor cell line BIU-87.Methods BIU-87 cells and cell extracts are cultured with asONS,non-asONS and control fluid at different concentrations and times respectively.Telomerase activity was assayed by TRAP PCR-ELASA.Results AsONS can inhibit the activity of BIU-87 cells ,whereas non-asONS and control group not, and have significant difference(P
ABSTRACT
Objective To investigate the effects of intravesical therapy with elemene in preventing postoperative recurrence of superficial bladder cancer and its toxic and side effects. Methods This series included 123 patients with superficial bladder cancer (T 1),consisting of transitional cell carcinoma GⅠ in 37 cases,GⅡ in 73 and GⅢ in 13.They all underwent surgical treatment. Postoperatively, they were randomly assigned to 2 groups:63 patients in elemene group received instillation of elemene (400 mg,once a week) 2 weeks after operation and 60 patients in mitomycin C (MMC) group received instillation of MMC(40 mg,once a week) 2 weeks after operation. The instillations were repeated for 6 weeks and thereafter monthly for 1 year.The recurrence rates,side effects,and NK cell activity before and after treatment were evaluated. Results The recurrence rate of elemene group (mean follow-up of 19.7 months) was 7.9% (5 cases),which was significantly lower than that (25.0%,15 cases) of MMC group (mean follow-up of 19.4 months;P
