AIM:To explore the effects of the combined use of human telomerase reverse transcriptase (hTERT) gene antisense oligodeoxynucleotide (ASODN) and cisplatin on apoptosis of HL-60 cells. METHODS:PCR-ELISA was used to determine telomerase activity in HL-60 cells untreated or treated with ASODN, the expression levels of hTERT protein were assayed by immunofluorescence using fluoresce isothiocyanate (FITC) label. Apoptosis was detected by DNA electrophoresis and flow cytomertric cell cycle analysis. RESULTS:The expression levels of hTERT protein and telomerase activity in HL-60 cells treated with ASODN were shown to decrease with time, the DNA fragments were obviously found and the percentage of apoptosis cells was significantly enhanced in HL-60 cells with the combined use of hTERT ASODN and cisplatin compared with the combined use of hTERT sense oligodeoxynucleotide and cisplatin or cisplatin alone, respectively. CONCLUSION:Inhibition of telomerase activity by hTERT ASODN increases the cisplatin-induced apoptosis of HL-60 cells.

ObjectiveTo evaluate the effects of selective cyclooxygenase-2 inhibitor nimesulide lone and combined with cisplatin on tumor growth,and Ki67 and Caspase-3 expression in lung cancer xenografts in nude mice. Methods The mice were randomly divided into 4 groups:the control group,the nimesulide group,the cisplatin group and the nimesulide combined with cisplatin group. A549 cells were injected into BALB/c nude mice subcutaneously.On the 21st day after treatment tumor tissues were collected,and the xenografts growth were observed. The expression of Ki67 and Caspase-3 were detected by immunohistochemical method.ResultsNimesulide combined with cisplatin could significantly inhibited the xenografts growth compared with nimesulide or cisplatin.The tumor inhibition rate was 44.33％ in the nimesulide group,53.61％ in the cisplatin group and 80.41％ in the nimesulide combined with cisplatin group (P ＜ 0.05).Immunohistochemical analysis showed that the expression rates of Caspase-3 was significantly increased in the nimesulide combined with cisplatin group (67.43 ± 23.57 ) ％,the cisplatin group (48.40 ± 20.37 ) ％,and the nimesulide group (38.65 ± 15.37)％,compared with the control group (27.63 ± 13.03)％ (P ＜ 0.05).The expression rate of Caspase-3 was significantly increased in the nimesulide combined with cisplatin group compared with the nimesulide group or the cisplatin group (P ＜ 0.05 ).The expression rate of Ki67 was significantly decreased in the nimesulide group combined with cisplatin group (24.34 ± 15.90)％,the cisplatin group (40.85 ± 22.47)％ and the nimesulide group (53.33 ± 19.67)％ compared with the control group ( 80.43 ± 16.88 ) ％ ( P ＜ 0.05 ).The expression of Ki67 was significantly decreased in the nimesulide combined with cisplatin group compared with the nimesulide group or the cisplatin group ( P ＜ 0.05 ).Conclusion Nimesulide can inhibit human lung cancer A549 cells xenografts in nude mice growth,Nimesulide enhanced the inhibitory effects of cisplatin.The mechanism may be related to inhibition of tumor cell Ki-67 expression,increased expression of Caspase-3,inhibition of tumor cell proliferation,and inducing tumor cell apoptosis.

p21 activated kinase 4 (PAK4) is a member of a family of serine/threonine kinase.PAK4plays an important role in a variety of cellular functions including cell cycle,cell proliferation,apoptosis,and cytoskeletal reorganization.Recently,PAK4 has been shown to overexpress in a variety of malignancies,and contribute to cancer cell migration and invasion through multiple signalling pathways.

The β-adrenergic receptor has close relationship with the occurrence and development of tumor.The β-adrenergic receptors were expressed in a variety of tumors.Its activation can stimulate tumor growth by promoting cell proliferation,inhibite apoptosis,promote angiogenesis,and enhance tumor invasion and metastasis.The β-adrenergic receptor blockers can suppress the tumor growth,which may become one of the effective methods of cancer prevention and treatment.

Objective To investigate the effectiveness of intensive sit-to-stand training in improving the balance and walking of hemiplegic stroke patients. Methods Sixty hemiplegic stroke patients were randomly divided into an observation group and a control group with 30 cases in each.Both groups were treated with routine rehabilitation.The observation group also underwent extensive sit-to-stand training.The training lasted for 15 min/time,6 times/week for 4 weeks.All of the patients were assessed with respect to their body weight distribution,Berg balance scale (BBS) scores,timed up & go test (TUGT) times and using footprint gait analysis,before the treatment and 4 weeks post treatment. Results After 4 weeks of treatment body weight distribution,BBS scores,TUGT times and gait improved significantly in both groups.The BBS,TUGT and gait improvements were significantly greater in the observation than in the control group.There was no significant difference between the two groups in terms of body weight distribution. Conclusions Extensive sit-to-stand training combined with routine rehabilitation can distinctly improve the balance and walking of hemiplegic stroke survivors.

Many cardiac sympathetic changes occur before clinical symptoms being found in heart disease.PET/CT imaging can sensitively detect abnormal cardiac sympathetic nerve function.The recent development of several 11 C and 18F labeled cardiac sympathetic imaging agents is reviewed in this paper.11C-meta-hydroxyephedrine (11 C-HED) and 6-18F-fluorodopamine (18F-FDA) have been comprehensively studied already.N-11C-CH3-dopamine (11C-MDA) and N-(3-bromo-4-(3-18F-fluoropropoxy)-benzyl)-guanidine (18F-LMI1195) are novel imaging agents with potential for clinical application.
