ObjectiveTo explore the mechanisms of proliferation and apoptosis of K562 cells induced by cytarabine. MethodsDifferent doses of cytarabine on the proliferotion at K562 cell 24h,48h,72h were detected by MTT. Cell cycle And Apoptosis rate were detected by FCM. ResultsEach concentration of cytarabine obvious inhibited the growth of K562 cells. In the same concentrations,function of proliferation inhibition with cytarabine increased by the extension of time,which showed dose and time effect relations. Cytarabine on K562 cell,G0/G1 phase cell proportion of role as cytarabine increased when extension of time, S period and the G2/M period cells were decreased.Apoptosis of K562 cell in proportion as drug concentration and effect time increases, which present Cytarabine timeconcentration dependence. CondusionCytarabine was apparent inhibition to proliferation of K562 cell leukemia cell, which could promote K562 cell apoptosis by time and concentration dependence way.

OBJECTIVE: To summarize research progress of tissue-engineered tendon stent material and its application for repairing tendon defect. METHODS: A computer-based online search was conducted with the key words of "tissue engineering, tendon, scaffold" in both Chinese and English from January 1993 to October 2009. Articles about dynamical performance of tissue-engineered tendon,experimental research and clinical application of tissue-engineered tendon were included, but duplicated studies and Meta analysis were excluded. Among 38 articles, 4 major viewpoints were discussed: research progress of tendon tissue engineering; biodynamical analysis of tissue-engineered tendon stent materials; application of biomaterials for tendon tissue engineering; clinical application of tissue engineering for repairing tendon defect. RESULTS: Natural polymer and synthetic macromolecule were major materials in tendon tissue engineering. The preparation and selection of stent materials depended on producing imitated materials with advanced performance and structure based on artificial synthetic materials, preparing natural derivative stent materials based on natural extracellular matrix, and constructing tissue-engineered tendon based on original bio-structure and bio-performance of biological tissue. Construction of tissue-engineered tendon must simulate three-dimensional physical environment in vivo. Microcomputer-controlled step motor was used to force tendon-matrix compound stent in order to increase proliferation velocity of tendon cells and secretory volume of collagen and develop into stress direction. CONCLUSION: Physical stimulation is simple, thus technique and instrument for constructing artificial tendon need to be further studied. Additionally, living implants which may completely replace body tissue and organ function still need to be further studied and solved.

Objective:To explore clinical significance of the further method dealt with in ASCUS(atypical squamous cells undetermined significance) of cervical smear.Methods:118 patients with ASCUS were detected by colposcopy and high risk HPV test,simultaneously make biopsy of cervical guided by colposcopy.Result:By diagnosed with pathology,chronic cervical inflammation is 72 cases,46 cases were CIN(cervical intraepithelial neoplasia).In this study 40 cases were positive in HPV test which 33 cases are CIN(?2=48.18,P0.05).Conclusion:There are high CIN csses in Women with ASCUS whose should be paid attention to and strengthen management.Colposcopy and high risk HPV test are efficiency method to ASCUS,especially high risk HPV test is positive that need detective by colposcopy.The combination of colposcopy and high risk HPV test can improve detective rate and accuracy of cervical intraepithelial neoplasia(CIN).

BACKGROUND:Tumor stem cels have self-renewal, drug resistance and metastasis tumorigenicity, which play an important role in occurrence, development and metastasis of tumors. Currently, there are two methods to identify tumor stem cels, namely, in vitro tumor sphere culture experiments and in vivo mouse tumorigenic experiments. However, there ia a lack of reports regarding clinicaly enriched gastric cancer cels by chemotherapy. OBJECTIVE:To investigate the enrichment of rat gastric cancer stem cels by cisplatin, and to explore the screening methods for their surface marker proteins. METHODS: BCG-823 gastric cancer model was established in rats, and then rat models were randomized into two groups: rats in experimental groups were subjected to intravenous injection of 0.1, 0.2, 0.25, 0.3 g/L cisplatin via the tail vein; those in control group were injected with normal salinevia the tail vein. After three courses of chemotherapy, gastric stem cels-enriched tissues were colected. Tumor surface proteins were extracted using high-throughput protein microarray and identified by western blot assay. Effects of cisplatin on enrichment of rat gastric cancer stem cels and screening methods for surface marker proteins were compared. RESULTS AND CONCLUSION:Cisplatin at a dose of 0.3 g/L×200μL exhibited the best therapeutic effects, and moreover, with the dose increasing, the tolerance became worse and the incidence of adverse reaction became higher. Transplantation tumors were verified by hematoxylin-eosin staining. Western blot test results were similar to the findings of protein microarray method, that is, HLA-DQ, PMP22 and Claudin7 protein expressions increased in gastric tissues, but HLA-DR, CD14, CD16 and CD56 protein expression decreased. These findings suggest that cisplatin can be used to enrich gastric cancer stem cels in rats, and to successfuly screen the corresponding surface marker proteins.

According to the constructivism learning theory,the paper analyzed the method and the value of applying the constructivism learning theory to teaching Acupuncture and Moxibustion Science in the universities and colleges of Chinese medicine from designing and developing the pedagogy platform and online learning courseware for Acupuncture and Moxibustion Science to the experiment of teaching mode and the effect on teaching experiment based on constructivism learning theory etc.The advantages and effect are also summed up in this article.

Objective To explore the influence of lifestyle intervention on obesity and diet behavior in children with simple obesity.Methods 80 simple obesity children were chosen as research subjects,the parents were given cognitive behavior intervention,the children were given lifestyle interventions to control weight.The changes of obesity degree and dietary behavior were observed after the interventions.Results After the intervention,the parents in the adjustment of dietary structure,limit the time of watching TV,limit of snack in.take were significantly higher than those before intervention(P ＜ 0.05).Children reduced meat,snack intake,watch TV time more than those before intervention(P ＜ 0.05).Obesity degree was significantly lower than that before intervention(P ＜ 0.05).Conclusion The lifestyle intervention is beneficial to change unhealthy life style in obese children,and to reduce weight.

Objective To investigate the effect of chain management on education among hypertensive patients of the community. Methods A total of 144 cases of hypertension patients in community were selected as the research objects, they were divided into the control group(72 cases, from February to July 2015) and the countryside group (72 cases, from September 2015 to February 2016).The control group was given routine education, and the countryside group received education with chain management. The treatment compliance and blood pressure values were compared between the two groups before and after intervention. Results The score of patients behavior of drug compliance, adverse drug, self life management and cigarettes-alcohol addiction management after intervention in the countryside group were (20.32±4.41), (34.62±5.08), (41.27±3.54), (10.02±1.79) points, while they were (13.41±3.07), (26.23 ± 5.12), (39.78 ± 2.47), (7.94 ± 1.83) points in the control group. And the scores of the countryside group were significantly higher than those of the control group (t=2.930-9.864, P<0.05). There were no significant differences in the systolic blood pressure, diastolic blood pressure and mean arterial pressure before the intervention between the two groups (P > 0.05). The systolic blood pressure, diastolic blood pressure and mean arterial pressure after intervention in the countryside group were (129.63 ± 8.07), (80.12 ± 7.62), (87.43 ± 9.35) mmHg(1 mmHg=0.133 kPa), while they were (135.42 ± 8.13), (87.56 ± 7.79), (99.31 ± 8.72) mmHg in the control group, and there were significant differences(t=4.295, 3.800, 9.201, P<0.01). Conclusions The chain management mode of community hypertension patients with education, can effectively improve the control of blood pressure in patients, improve the treatment compliance of patients.
