AIM: To investigate the roles of overexpression of RON receptor tyrosine kinase in motile/invasive ability of human colorectal cancer cell line RKO.METHODS: A eucaryotic expression vector pDR2 containing full-length wt-RON cDNA was transfected into the colorectal cancer cell line RKO and a stable expression clone was obtained.The motile/invasive ability was tested by wound healing test and the transwell migration assay.The expression of E-cadherin was measured by Western blotting.RESULTS: Motile ability of transfected RKO was greatly promoted by transwell chemotaxis assay(P

The autonomy is one of the basic authorities of patients.It isn't only an ethical concept,but also can help enhance the efficacy and compliance to a certain extent.The autonomic behavior of the patients isn't as optimistic as we think.The patient's autonomy can be influenced by many factors.We should base on the principles,advantage,respect and communication,to encourage patients to make an appropriate and unbiased decision and change into a collaborative,patient-centered doctor-patient relationship model.

Proteomics was important for the coherent study of human reproduction and animal breeding including human infertility,sperm-egg binding and mutual recognition of the mechanism.It was well known that proteomics had become one of the main branches of life sciences in the future.This provides the technological means and theoretical foundation for the individual dynamic changes in the protein.At the same time,it plays an important role in the drug development,the mechanism of life activities and in the field of livestock breeding.

Objective The purpose of this study was to establish a rapid method for synthesis and detection of guild RNA (gRNA) which is an essential component in CRISPR/Cas9 knockout technology .Methods First, the Nkp46 gRNA core fragment was synthesized as amplification template .Second , the forward and reversed primers of the matched gRNA were designed using the Nkp46 gene as reference sequence .Third, the DNA fragment of Nkp46 gRNA was amplified by PCR technology using the synthesized gRNA core fragment as template .The gRNA was reversely transcribed in vitro u-sing amplified DNA fragment as template .The efficiency and specificity of gRNA and its interaction with Cas 9 were detec-ted in vitro.Results The specificity and activity of Nkp46 gRNA were high .The obtained gRNA interacted with Cas 9 en-zyme and successfully cut the target double-stranded DNA at the designed site .Conclusions The method for synthesis and detection of gRNA established in this study is faster than the original method , and the created gRNA is fully functional .

BACKGROUND: As the first long-acting atypical antipsychotics, the therapeutic effect and safety of risperidone microsphere have been proved. However, it may lead to serious pain due to the deep intramuscular injection.OBJECTIVE: To evaluate the pain levels by 12-week injection of rispeddone microsphere and to explore the relationship among dose and times of injection of risperidone microsphere and pain levels.METHODS: A total of 57 patients diagnosed as schizoprenia by DSM-Ⅳ, aged 18-65 years, were selected and injected risperidone microsphere once every 2 weeks with doses of 25, 37.5 and 50 mg. The pain levels were evaluated using 100 mm visual analogue scale during injection and at the injected sites. The effects of injected dose, injected frequency and injected sites on the pain were analyzed by the nurse questionnaire.RESULTS AND CONCLUSION: The pain levels among the different doses groups had no notable differences (F=1.35,P> 0.05), which demonstrated that the pain had no relationship with injected dose. However, the pain level of injected sites had correlation to injected doses. The pain level of the 50 mg group was greater than that of the 37.5 and 25 mg groups. Accordingly,patients who treated by high dose of risperidone microsphere should be intervened by nurses.

Lack of protection in education was one of possible reason contributed to the traditional Chinese medicine(TCM) psychology pathogenesis while the research conducted. This paper discusseds the following aspects: the concept, the causes, the impact and the types of protection. It also provided series thought on the development of TCM psychology pathogenesis, TCM psychology family treatment and family education of TCM psychology prevention.

For the research of TCM psychology pathogenesis, one possible reason could be concluded on the abnormal digestive process in psychology. This study discussed the concept of abnormal digestive process in psychology, including abnormal acception, digestion and metabolism in psychology. It provided foundation for the development of TCM psychology pathogenesis and TCM psychology clinical therapy.

During the research of TCM psychology pathogenesis, one possible reason may be theretardative solipsism thinking was one of TCM psychology pathogenesis in the study of TCM education therapy. This study discussed the concept of retardative solipsism thinking and its five types including personal preference type, selfishness type, arrogant type, autism type and escaping type.It provides foundation for TCM psychology clinical therapy.

Objective To observe expression of human beta-defensin-3 (HBD-3) in tissues around the infected artificial prostheses and investigate its value in treatment and diagnosis of periprosthetic joint infection (PJI).Methods According to clinical diagnosis,periprosthetic tissues and normal synovial membrane excised in operation were collected and divided into the following four groups:PJI group (n =13),aseptic loosening group (loosening group,n =9),spacer treatment group (treatment group,n =12),and normal group (n =15).HE staining was used to observe infiltration of inflammatory cells.Immunofluorescence staining was used to detect positive cells number and fluorescence intensity.Image-pro plus (IPP) 7.0C software was used to measure the average value of absorbance.Preoperative peripheral white blood cell count,erythrocyte sedimentation rate (ESR),and C-reactive protein (CRP) results were documented.Then,differences of those parameters were analyzed and compared among groups.Results HE staining revealed that all groups had different degree of inflammatory cell infiltration except for normal group.Immunofluorescence staining revealed that the most number of positive cells and highest fluorescence intensity existed in PJI group.Value of absorbance in PJI group was 0.430 ± 0.013,followed by 0.308 ±0.005 in loosening group,0.234 ± 0.009 in treatment group,and 0.089 ± 0.019 in normal group.Preoperative peripheral white blood cell count,ESR and CRP were the highest in PFI group,but were not significantly different among the remaining three groups.Conclusion HBD-3 is highly expressed in tissues around the prostheses which had infection or aseptic loosening,but its expression in response to infection and loosening has difference.
