Objective:To investigate the effect of focal adhesion kinase related non kinase (FRNK) on the activation and migration of hepatic stellate cells (HSCs).Methods:Human liver tissue was divided into healthy control group and fibrosis group from March 2019 to September 2019 in Affiliated Hospital of Guizhou Medical University. C57BL/6 mice were divided into wild type (WT) and FRNK gene knockout type (FRNK -/-) groups. The liver fibrosis model was established with carbon tetrachloride (CCl 4). After that, FRNK gene overexpression (Ad-FRNK) was constructed with adenovirus vector. HE and Masson staining were used to evaluate the pathological changes and fiber deposition of liver tissue. Western blot was used to detect the expression of PY397-FAK and α-SMA protein. Mouse primary HSCs were extracted, and the effect of FRNK on HSCs migration was detected by wound healing, activation of Rac and Rho was detected by Western blot. Results:The expression of PY397-FAK protein in human liver tissue with hepatic fibrosis was significantly higher than that in healthy control group (0.88±0.09 vs. 0.73±0.09). FRNK was significantly lower than that in control group(0.68±0.09 vs. 0.79±0.11). After animal model was set up, the degree of liver fibrosis in FRNK -/-mice (153±13)% was more serious than that in WT (100%) group. The expression of PY397-FAK and α-SMA protein was significantly elevated (2.50±0.23 vs. 0.75±0.09, 1.46±0.20 vs. 0.92±0.10). After FRNK gene was re-expressed (100%), the degree of liver fibrosis was mainly reversed [(74±6)%], and the expression of PY397-FAK and α-SMA was accordingly decreased(0.68±0.11 vs. 1.12±0.19,0.68±0.10 vs. 0.85±0.06). In vitro, FRNK inhibited the migration of HSCs [WT∶FRNK -/-∶Ad-FRNK,(339±49)%∶(580±53)%∶(259±33)%] and the activation of Rac and Rho proteins (Rac: 0.54±0.07 vs. 0.91±0.10 vs. 0.77±0.12,Rho:0.45±0.05 vs. 0.64±0.06 vs. 0.53±0.07), all P<0.01. Conclusions:FRNK can inhibit the activation and migration of HSCs which contributed to liver fibrosis. The potential mechanism is related to down regulation of PY397-FAK and inhibition of Rac and Rho activation.

Objective: To analyze Nursing Occupational Risk, the relationship between resilience and job performance, and investigate the mediating effects of resilience on Nursing Occupational Risk and job performance. Methods: 406 nurses from33 clinical departments of Chengdu first-class hospital were recruited by randomsampling method. Thier Nursing Occupational Risk, resilience and job performance were interviewed by nursing occupational risk assessment questionnaire, the Scale of medical staff resilience and the job performance questionnaire, and analyze the relationship between variables. Results: The clinical nurses＇ resilience is 82.98±10.05, the clinical nurses' job performance is 145.79±23.55; here was a positive correlation between clinical nurses' resilience and job performance (P<0.05) ; three variable of resilience can explain 33.2% of the variation of clinical nurses job performance; in the highest the Nursing Occupational risk, resilience served to mediate the relationship between Nursing Occupational Risk and job performance, which was 56.77% of the total effect respective. Conclusion resilience are closely related to job performance. Resilience plays mediating role in the relationships between Nursing Occupational Risk and job performance, three dimensions of resilience can predict nurses' job performance. Improving the resilience of nurses can effectively improve their job performance.

Extrachromosomal DNA (ecDNA) is a small segment of circular DNA located outside the chromosome, which has the function of self-replication. Recently, amplification of oncogenes on ecDNA has been proved to be a common phenomenon in tumor cells, and has some characteristics worth studying, such as correlation with patients' poor prognosis. Multiple chromosomal events are involved in the formation of ecDNA, and its amplification can directly increase the number of DNA copies of extra-chromosomal oncogenes and accelerate the generation and development of tumors. Moreover, the segregation pattern of unequal transmission of parental ecDNA cells to offspring not only increases tumor heterogeneity, but also enhances tumor adaptation to environment and response to therapy. This article reviews the current status and potential significance of ecDNA in tumor cells.

Gastric cancer is the most common gastrointestinal cancer in China. The morbidity and mortality are extremely high and there are significant challenges in the treatment of gastric cancer. Recent studies have shown that the expressions of T lymphocyte subsets vary in the immune microenvironment of gastric cancer patients. T lymphocytes are not only the main effector cells of human cellular immunity, but also the important immunoregulatory cells. T lymphocytes not only reflect the state of the tumor microenvironment, but also closely relate with the prognosis of patients. T lymphocytes play a crucial guiding role in the clinical treatment. Currently, clinical trials related to immunological checkpoint inhibitors are still underway, among which PD-1/PD-L1 monoclonal antibody has been approved for the treatment of gastric cancer. The applications of tumor vaccines and adoptive cell therapies in gastric cancer are also being explored. How to screen patients suitable to immunotherapy, develop the best combination therapy and evaluate the effectiveness of immunotherapy need to be studied and solved.

OBJECTIVE: To evaluate the effects of the pestle needling therapy on the vibration perception threshold (VPT) and the quality of life (QOL) in the patients of high-risk diabetic foot. METHODS: A total of 132 patients of high risk diabetic foot were randomized into an observation group and a control group, 66 cases in each one. In the control group, the routine treatment and nursing for diabetes were applied. In the observation group, on the base of the treatment as the control group, the pestle needling therapy was used at , , , Zusanli (ST 36), Yongquan (KI 1), Sanyinjiao (SP 6) and Taixi (KI 3). The intervention with the pestle needling therapy was given once every day, consecutively for 4 weeks. The follow-up visit was conducted in 3 months and 6 months after the intervention. Vibration perception threshold (VPT) was observed before and after intervention in the two groups. Separately, before intervention, at the end of intervention, 3 months after intervention and 6 months after intervention, the type 2 diabetes mellitus quality life scale (DMQLS), the revised edition was adopted to compare the QOL between the two groups. The effects were evaluated in the two groups. RESULTS: After intervention, the VPT and QOL were all improved in the two groups (<0.01, <0.05). In the observation group, after intervention, VPT at the first toes and the dorsum of the feet was lower than the control group at the same time point (all <0.01). In the observation group, the total scores and the score of each dimension item in the DMQLS of the revised edition were all lower than the control group correspondently at the end of intervention, 3 months after intervention and 6 months after intervention (<0.01, <0.05). The repeated ANOVA results showed that the differences were significant in the total scores and the score of each dimension in the aspects of time, inter-group and interaction effect (<0.01, <0.05). The total scores and score of each dimension item in the DMQLS were lower than those the earlier time point (<0.01, <0.05). The total effective rate was 100.0% in the observation group, which was superior to 95.1% (59/62) in the control group (<0.05). CONCLUSION The pestle needling therapy reduces the foot VPT and improves the sensory nerve function of the foot and the QOL in the patients of high-risk diabetic foot.
