Objective To explore the cancer incidence in registration areas in Shanxi Province. Methods Data of 8 cancer registration areas in 2011 were taken into account and cancer incidence in different areas with different ages was compared with that in other domestic areas. Results 8 395 new cases in Shanxi all cancer sites were reported in 2011, including 4 810 male and 3 585 female. The incidence of malignant cancer of Shanxi was 207.53/100 000, and the standardized incidence of Chinese population and world population were 125.20/100 000 and 165.72/100 000, respectively. In urban areas, the incidence of Shanxi and the standardized incidence of Chinese population were 202.49/100 000 and 112.81/100 000, respectively. In rural areas, incidence rate of Shanxi was 211.96/100 000 and the standardized incidence of Chinese population was 138.43/100 000. In Shanxi Province, the major malignant cancer sites for males involved stomach, lung, esophagus, liver and colorectum, and cancer sites for females were more on cervix, lung, breast, stomach and esophagus. Conclusions Upper gastrointestinal cancer and uterine cervix cancer are the major cancers in Shanxi registration areas. The incidence of stomach cancer and uterine cervix cancer in Shanxi Province are much higher than national average.

AIM: To look for harmfulless anti-leukemia drug with selective high performance, lethal effect of small hairpin RNA (shRNA) on VEGFR2 gene expression of tumor cell line HL60 in vitro.METHODS: The most effective VEGFR2 siRNA was designed and screened. The shRNA oligo was designed and pU6/VEGFR2 entry clone was constructed. HL60 was transfected transiently and vascular endothelial growth factor receptor 2(VEGFR2) expression was tested with MTT assay, RT-PCR and Western blotting. The expression clone was constructed and cotransfected with ViraPowerTM Packaging Mix into 293FTTM cells to produce Lentiviral vectors harboring Lenti6/shVEGFR2. The virion supernatant was added into HL60 cells and VEGFR2 gene inhibitory effect was determined. RESULTS: The inhibitory rates of VEGFR2 siRNA c were high. VEGFR2 expression in HL60 was inhibited by using pU6/VEGFR2 entry clone constructed with shRNA and pENTRTM/U6. For HL60 cells, the inhibitory rate was 84.9%. The expression of VEGFR2 mRNA and protein decreased significantly. 48 hours after transfection of pU6/shVEGFR2 entry clone and transduction of Lenti6/shVEGFR2 expression clone, the cell inhibitory rates were similar. Cell growth inhibitory rate of entry clone descended rapidly after this time point, the expression clone changed slowly, reaching the peak at 96 hours, dropped slightly, having no significance deviation. CONCLUSION: in vitro, VEGFR2 shRNA using lentiviral vector blocks VEGF/VEGFR2 self-secretion in HL60 cells, which inhibits leukemia development.

Objective To investigate the clinical therapeutic effect of electroacupuncture on ischemic stroke by recording the therapeutic effect score and performing transcranial Doppler (TCD) detection in electroacupuncture-treated convalescent stroke patients before and after treatment.Methods Sixty convalescent patients with ischemic stroke were randomly allocated to treatment and control groups, 30 cases each. The control group received routine medication and the treatment group, electroacupuncture in addition. In the two groups, pre- and post-treatment neurological defect scores were recorded and the clinical therapeutic effects were observed after four weeks of treatment. Pre- and post-treatment middle cerebral artery (MCA) pulsation indices (RI), resistance indices (RI) and ratios of systolic to end-diastolic (S/D) blood flow velocity detected by TCD were compared between the two groups. Results The total efficacy rate was 80.0% in the treatment group and 50.0% in the control group; there was a statistically significant difference between the two groups (P<0.01). There was a statistically significant pre-/post-treatment difference in the MESSS score in the two groups (P<0.01). There was a statistically significant post-treatment difference in the MESSS score between the treatment and control groups (P<0.05). There were statistically significant pre-/post-treatment differences in TCD indices (PI, RI and S/D) on the affected side in the two groups (P<0.05). There were statistically significant post-treatment differences in TCD indices on the affected side between the treatment and control groups (P<0.05).Conclusion Electro- acupuncture can promote rehabilitation in convalescent stroke patients.

Aim The aim of this work was to study the effect of diallyl disulfide (DADS) on human Leukemia cell line HL 60, and investgate the mechanisms of its antitumor effect. Methods HL 60 cells growth inhibition was measured by MTT assay. Cell apoptosis was inspected by flow cytometry,TUNEL assay and acridine orange fluorescent staining methods. The protein levels of Bcl 2, Bax were determined using immunohistochemical technique. Results MTT assay showed that DADS significantly inhibited the growth of HL 60 cells. After 24 hours of exposure to DADS, Partial cells presented characteristic morphological changes of apoptosis under the electron microscope, including cell shrinkage, nuclear condensation, and formation of apoptotic bodies. Some typical subdiploid peaks before G 0/G 1 phase were observed. Flow cytometry analysis revealed that the apoptosis rates were increased and the TUNEL assay showed the apoptosis index increased in occordance with increase of concentration of DADS. SP immunohistochemistry revealed that the Bax expression was increased while Bcl 2 expressed was decreased. Conclusion Diallyl disulfide could significantly induce apoptosis of human Leukemia cell HL 60, Apoptosis of tumor cells is closely associated with down regulation of the ratio of bcl 2/bax.

It was prepared by using Sophoraflavescens and Dictamnus dasycarpus as materials with the addition of Aloe extract, essential oil, surfactant, etc. The antifungal and antibacterial activity was researched by the levitation liquid quantitative method. The foot wash smelled faintly scent. The use of this product can produce a rich foam. The inhibitory rate were all more than 90%. The preparation process of the foot wash was simple. It has obviously bacteriostatic and fungistatic effect.

OBJECTIVETo investigate the effects of CD137-CD137L interaction on the nuclear factor of activated T cells c1 (NFATc1) in apolipoprotein E knockout (ApoE(-/-)) mice.

METHODSAtherosclerotic plaque model was produced by rapid perivascular carotid collar placement in ApoE(-/-) mice. In vivo, the expression of NFATc1 in mice plaque and lymphocytes was detected by immunohistochemical and flow cytometry, respectively. In vitro, the NFATc1 mRNA and protein expressions in cultured lymphocytes of ApoE(-/-) mice were measured by RT-PCR and flow cytometry, respectively.

RESULTSIn vivo, after stimulating CD137-CD137L signal pathway, the expression of NFATc1 was significantly upregulated in the atherosclerotic plaques and lymphocytes. In vitro, the mRNA and protein expressions of NFATc1 in cultured leukocytes of ApoE(-/-) mice were also significantly increased, the maximal effect appeared post 20 µg/ml anti-CD137 mAb-stimulation and reached maximum at 24 h at any concentrations. Anti-CD137L mAb significantly downregulated the mRNA and protein expressions of NFATc1 in lymphocytes of ApoE(-/-) mice, maximal effect appeared at 20 µg/ml anti-CD137L mAb and reached minimum at 24 h.

CONCLUSIONCD137-CD137L interactions can modulate the expression of NFATc1 in this ApoE(-/-) mice atherosclerotic plaque model.
