The development of effective therapy for children with acute lymphoblastic leukemia (ALL) is one of the greatest successes of clinical oncology. However, cure rates for adults with ALL remain relatively low. Adolescents are the special population between children and adults. These patients group will be received protocol from either pediatric or adult oncologists depending on referral pattern. In recent years, researchers from abroad large cooperative groups show pediatric-based protocol has better outcome than adult-based protocol. In this article, the protocol of ALL in children and adults are compared . It seems the first and probably the most important reason is the dose intensity of the nonmyelosuppressive chemotherapeutic agents, especially asparaginase.

Objective To find the mechanism of traditional Chinese medicine Heshouwuyin(HSWY) in anti-aging in ovary of the aging model rats,so as to provide theoretical and experimental evidence to anti-aging in female sexual gland.Methods Thirty-six rats were divided into three groups at random: normal group,aging model group,prevent aging group.Rats the in prevent aging group were subdivided into four groups: HSWY low dosage group,HSWY medium dosage group,HSWY high dosage group and Heshouwan(HSWW) group.The sub-acutely aging model rats were induced by D-galactose,and rats in the prevent aging group were received intragastric administration of HSWY and HSWW with D-galactose intraperioneal injection.The gene expressions of p53,p19~(ARF),Rb and p16 were detected in the ovaries of each group with reverse transcription polymerase chain reaction,and the protein expressions of Rb and p16 in the ovaries with Western blotting.Results The model group rats were in the aging status with low spirits and withered and yellowed hair.The ovaries of the rats in the model group expressed aging change.The gene expressions of p53,p19~(ARF),Rb and p16 were up-regulated and the protein expressions of Rb and p16 were increased in the ovaries of aging rats.HSWY significantly suppressed the gene expressions of p53,p19~(ARF),Rb and p16(P

Objective: To investigate the expression of histone deacetylase 2 (HDAC2) in esophageal squamous cell carcinoma (ESCC), and to explore the effects of downregulation of HDAC2 expression on cell proliferation, cell cycle and apoptosis of EC9706 cells and their possible molecular mechanisms. Methods: The expression of HDAC2 protein in ESCC tissues was detected by immunohistochemistry. HDAC2 small interfering RNA (siRNA) and control siRNA were transfected into ESCC EC9706 cells, and then the EC9706 cells were randomly divided into three groups, including untreated group, siRNA control group and HDAC2 siRNA group. The expression of HDAC2 protein in EC9706 cells was detected by Western blotting. The cell proliferation status was examined by cell counting Kit-8 (CCK-8) method. The cell cycle and apoptosis were detected by flow cytometry (FCM). The expressions of proteins related to cell proliferation, cell cycle and apoptosis were detected by Western blotting. Results: The positive expression rate of HDAC2 in ESCC tissues (79.71%) was significantly higher than those in normal esophageal mucosa (51.11%) and paracancerous tissues (dysplasia, 23.19%), and there was a significant difference among these three tissues (χ2=44.121, P=0.000). The expression of HDAC2 protein wasnot associated with age and gender of patients with ESCC (both P>0.05), but closely associated withhistological grade, invasive depth, TNM stage and lymph node metastasis (all P<0.05). HDAC2 siRNA effectively down-regulated the expression of HDAC2 protein, obviously inhibited the cell proliferation, arrested cell cycle at G0/G1 phase and induced apoptosis of EC9706 cells. In addition, the result of Western blotting showed that down-regulation of HDAC2 expression could markedly increase the expressions of p21 protein and apoptosis-related bax protein while decrease the expressions of cyclin D1 and bcl-2 proteins. Conclusion: HDAC2 may play an important role in occurrence and development of ESCC. The downregulation of HDAC2 expression-mediated proliferation inhibition, cell cycle arrest and apoptosis of EC9706 cells may be tightly associated with the increased expression levels of p21 and baxas well as the decreased expression levels of cyclin D1 and bcl-2.

One hundred and twenty four patients with cervical intra-epithelial neoplasia(CIN group)and 300 women in routine health check(control group)were recruited in the study.Ureaplasma urealyticum(UU)DNA in cervical secretions was detected by fluorescent quantitative PCR(FQ-PCR),and detectopm pf HPV was also performed in 103 CIN cases.The positive rate of UU was 64.5%in CIN group and 38.7%in control group(P＜0.05).The results demonstrated that UU infection may be associated with cervical intra-epithelial neoplasia,especially for high-grade lesions;and there may be interaction between UU and HPV infection in development of CIN.

Objective To evaluate the distribution characteristics of left ventricular systolic dyssynchrony (LV-SD) in dilated cardiomyopathy (DCM) patients with chronic heart failure (CHF) and normal QRS wave width, by pulsed-wave Doppler tissue imaging (PW-DTI), and study its relation with left ventricular systolic function, ventricular remodeling, and functional mitral regurgitation (FMR). Methods The time to peak systolic velocity (Ts) in 12 left ventricular segments was evaluated by PW-DTI, from which the standard deviation (SD) of Ts in the 12 segments (Ts-SD) and maximum Ts difference (Ts-maxD) were calculated. Results Ts-SD and Ts-maxD in the 12 LV segments of the DCM patients with CHF were significantly higher than those of the healthy controls (P＜0.01). In DCM patients with CHF and normal QRS wave width, the incidence of LV-SD was 29.8% (14/47) and the inferior wall was the most frequent distribution site of contraction delay. Linear regression analysis revealed a negative correlation between Ts-SD, Ts-maxD, and left ventricular ejection fraction (LVEF) (P＜0.01), but a positive correlation between Ts-SD, Ts-maxD and left ventricular end-diastolic volume (LVEDV), lefe ventricular end-systolic volume (LVESV), New York Heart Association (NYHA) cardiac function, FMR (P＜0.01) in DCM patients with CHF. Conclusion LV-SD exists in DCM patients with normal QRS width. LV-SD aggravates the LV systolic function damage, which is closely associated with left ventricular remodeling. LV-SD may contribute to the FMR in DCM patients.

Objective To explore the changes of GRO-α and VEGF in the peritoneal fluid of women with endometriosis and their correlation. Methods The levels of GRO-α and VEGF were detected by enzyme linked immunosorbent assay ( ELISA ) method in 39 cases of endometriosis and 25 normal cases of without endometriosis. Results The levels of GRO-αand VEGF in the peritoneal fluid of EMs group were ( 108.77 ± 20. 58 ) pg/ml and ( 199. 67 ± 99. 26 ) pg/ml separately, and it was significantly higher than those in control group ( 71.07 ± 18. 96 ) pg/ml, ( 115.46 ± 32. 39 ) pg/ml. The differences were statically significant( P <0. 05). The level of GRO-α in the peritoneal fluid of the patients in stage Ⅰ and Ⅱ was sig-nificantly lower than that in stage Ⅲ and Ⅳ[(99.43 ± 16.05)pg/ml vs (117.65 ± 20.8)pg/ml, P <0. 05] , while the level of VEGF in the peritoneal fluid of the patients in stage Ⅰ and Ⅱ was significantly higher than that in stage Ⅲ and Ⅳ[(246. 89 ± 114. 34) pg/ml vs ( 152. 82 ± 54. 55 ) pg/ml, P < 0. 05] .There was positive correlation between the level of GRO-α and r-AFS ( r = 0. 439, P < 0. 05 ), but no cor-relation between the level of VEGF and r-AFS ( r = -0. 210, P >0.05). There was no correlation be-tween peritoneal fluid levels of GRO-α and VEGF in the EMs group ( r =-0. 05, P>0. 05). Conclusion Compared with control group, the levels of GRO-α and VEGF in peritoneal fluid of women with endome-triosis were significantly increased, which indicated that the increased GR0-α and VEGF secretion involved in the pathogenesis of this disease. There was correlation between the peritoneal fluid level of GRO-α and the degree of EMs.

AIM:To study the effects of different duration of sleep deprivation (SD) on neurogranin (Ng),protein kinase C (PKC) and Ca2+-calmodulin dependent protein kinase II (CaMK II) mRNA expressions in hippocampus and forebrain of rats. METHODS:Male Wistar rats were divided into three groups:24 h,48 h and 72 h experimental groups. Each group was divided into sleep deprivation group (SD group) and control group (C group). SD model was established by sleep deprivation box. One step methods by Trizol was used to extract hippocampus and forebrain neuronal total RNA. The changes of Ng,PKC and CaMK II mRNA expressions were detected by SYBRA green I RT-PCR. RESULTS:(1) The expression of Ng mRNA in hippocampus of SD group was significantly lower than that in C group after 24 h,48 h and 72 h SD (P

Objective To study and to analyse the cause of laparoscopic adrenalectomy failure and its complications. Methods 8 of 19 laparoscopic adrenalectomies were converted to open surgery .The cause of failure and its complications were analysed. Results The causes to convert to open surgery were:bleeding of right middle suprarenal vein in 1,adrenal tumor was sheltered of cauda pancreatis in 1,left adrenal cyst was sheltered by spleen in 1,CO 2 pneumoperitoneal pressure can not be maintained during the procedure in 2,tumers could not be found in 2,the telescopic port was inserted into musculus psoas major in the retroperitoneal approach and the bleeding influenced the operation field in 1.3 patients had high fever after operations and 1 had an abscess in the adrenal bed.Reactive pleuritis occurred in 1. Conclusions Fine technique and experiences were needed for laparoscopic procedures and good team work between the operators was very important.Complications were often associated with the initial cause that led to the laparacospic adrenalectomy failure.Laparoscopic adrenalectomy via the retroperitoneal approach has been easier than that via the transperitoneal approach.

Objective To study the diagnosis, treatment, and prognosis of implantation metastasis to abdominal incision after open operation for bladder carcinoma. Methods 10 cases of implantation metastasis to abdominal incision after open operation for bladder carcinoma encountered from 1985 to 1999 were retrospectively studied,nine being male and 1 female.The average age was 52.7 years. Results These were 6 transitional cell carcinoma (all were grade G 3),2 transitional cell carcinoma with squamous carcinoma or adenocarcinoma,1 squamous carcinoma,and 1 adenocarcinoma.The diameter of the metastasis lesion was 1.4～11.5 cm?1.0～6.9 cm.The treatments included total cystectomy with resection of metastasis,TURBt with resection of metastasis,urinary diversion with chemotherapy and/or radiotherapy, resection of metastasis with chemotherapy and/or radiotherapy, and chemotherapy and/or radiotherapy alone.7 of the 10 died of the carcinoma,the survival times being 4～41 months (average 13 months).Only 1 patient survived for 41 months.Whereas the others died within 14 months.3 patients are still alive for 5～9 months with no recurrence. Conclusions The differentiation of the cancer cells of implantation metastasis is usually bad and often accompanied by squamous followed by carcinoma or adenocarcinoma.Total cystectomy with resection of the metastasis followed by chemotherapy and/or radiotherapy might prolong the survival time, but the prognosis is usually poor.
