Objective To explore how to promote the early medical consultation of patients with advanced esophageal cancer to improve the curative rate and the survival rate. Methods With the phenomenological research method, 12 patients with advanced esophageal cancer were sampled for the research. The semi-structure interview method was conducted to collect the data for analyses. Result There were 6 factors influencing the early consultation from the patients with advanced esophageal cancer in their early medical treatment, which included 6 items: lack of knowledge of the disease, economic burden, ignorance of early symptoms, lower medical level, heavy psychological burden of the disease, ageing and delay in seeking medical care. Conclusions The promotion of early medical treatment to the patients with esophageal carcinoma is in critically emergency. The measures including reducing economic burden, corresponding nursing care and health education can improve the cure rate and life quality.

Objective:To explore whether the action research on the pre-service training evaluation system of "Internet + TCM Nursing" guided by CIPP (context, input, process and product) and Kirkpatrick Model can improve the training effect of nursing staff under the background of internet and TCM nursing service.Methods:Taking 211 nurses of "Internet + TCM Nursing" in Guangdong Provincial Hospital of TCM from 2019 to 2020 as the research objects, action teams were made, and the data were collected and analyzed by various methods. According to the collected data, the action teams constructed the training scheme of "Internet + TCM Nursing", the compilation requirements of "internet + TCM Nursing", the case optimization scheme of "internet + TCM Nursing" process, and the evaluation model of "internet + TCM Nursing". After the training, the nurses' knowledge, skills and related attitudes, the general reaction and feelings to the training programs, and the evaluation of nurses' work performance by the competent leaders, medical staff and clients were compared by comparing their scores and issuing self-made questionnaires. SPSS 20.0 software was used for statistical analysis.Results:The results showed that the theoretical scores of nurses after training were (85.16±6.22) points, and the case assessment scores after training [(81.22±7.03) points] were higher than the previous theoretical scores [(61.23±12.90) points] and the case assessment scores [(59.54±14.41) points], with statistical significance ( P<0.001). The results of self-made questionnaire showed that there were significant differences in theoretical knowledge, skills and related attitudes among nurses after training ( P<0.001). In the process of training, there were statistically significant differences in training content, teacher training, training implementation and training guarantee at the end of training ( P<0.001). After training, there were significant differences in the evaluation of nurses' job performance by leaders in charge, medical staff and clients improved in knowledge and skills, professional ethics, working process and learning ability, and the improvement rate ( P<0.001). Conclusion:Action research is an effective research method to continuously improve nursing training. The optimization scheme of "internet + TCM Nursing" nurses based on CIPP and Kirkpatrick Model through action research can effectively improve the training effect.

At present, there are many problems in the nail-fold microcirculation detection devices, such as huge structure, inconvenience to carry. In addition, due to the patient's body shaking, the video is difficult to keep stable in collecting with the device, which brings great difficulties to the doctor's observation. We develop a small image acquisition device for nail-fold microcirculation based on the principle of SDF imaging principle and liquid lenses technology. An annular lighting device is fixed in front of the optical system, and the overall design of the system is based on the characteristics of human fingers. The device is small, easy to carry and conform to the fingertips. It can focus quickly through a controller. It can also achieve high quality images of the nail-fold microcirculation. This study can promote the usage of nail-fold microcirculation device at the bedside. It's an efficient tool for medical workers to observe the microcirculation of patients.

OBJECTIVE:
To investigate the effects and underlying mechanisms of VX765 on osteoarthritis (OA) and chondrocytes inflammation in rats.
METHODS:
Chondrocytes were isolated from the knee joints of 4-week-old Sprague Dawley (SD) rats. The third-generation cells were subjected to cell counting kit 8 (CCK-8) analysis to assess the impact of various concentrations (0, 1, 5, 10, 20, 50, 100 μmol/L) of VX765 on rat chondrocyte activity. An in vitro lipopolysaccharide (LPS) induced cell inflammation model was employed, dividing cells into control group, LPS group, VX765 concentration 1 group and VX765 concentration 2 group without obvious cytotoxicity. Western blot, real-time fluorescence quantitative PCR, and ELISA were conducted to measure the expression levels of inflammatory factors-transforming growth factor β 1 (TGF-β 1), interleukin 6 (IL-6), and tumor necrosis factor α (TNF-α). Additionally, Western blot and immunofluorescence staining were employed to assess the expressions of nuclear factor erythroid 2-related factor 2 (Nrf2) and heme oxygenase 1 (HO-1). Thirty-two SD rats were randomly assigned to sham surgery group (group A), OA group (group B), OA+VX765 (50 mg/kg) group (group C), and OA+VX765 (100 mg/kg) group (group D), with 8 rats in each group. Group A underwent a sham operation with a medial incision, while groups B to D underwent additional transverse incisions to the medial collateral ligament and anterior cruciate ligament, with removal of the medial meniscus. One week post-surgery, groups C and D were orally administered 50 mg/kg and 100 mg/kg VX765, respectively, while groups A and B received an equivalent volume of saline. Histopathological examination using HE and safranin-fast green staining was performed, and Mankin scoring was utilized for evaluation. Immunohistochemical staining technique was employed to analyze the expressions of matrix metalloproteinase 13 (MMP-13) and collagen type Ⅱ.
RESULTS:
The CCK-8 assay indicated a significant decrease in cell viability at VX765 concentrations exceeding 10 μmol/L ( P<0.05), so 4 μmol/L and 8 μmol/L VX765 without obvious cytotoxicity were selected for subsequent experiments. Following LPS induction, the expressions of TGF-β 1, IL-6, and TNF-α in cells significantly increased when compared with the control group ( P<0.05). However, intervention with 4 μmol/L and 8 μmol/L VX765 led to a significant decrease in expression compared to the LPS group ( P<0.05). Western blot and immunofluorescence staining demonstrated a significant upregulation of Nrf2 pathway-related molecules Nrf2 and HO-1 protein expressions by VX765 ( P<0.05), indicating Nrf2 pathway activation. Histopathological examination of rat knee joint tissues and immunohistochemical staining revealed that, compared to group B, treatment with VX765 in groups C and D improved joint structural damage in rat OA, alleviated inflammatory reactions, downregulated MMP-13 expression, and increased collagen type Ⅱ expression.
CONCLUSION
VX765 can improve rat OA and reduce chondrocyte inflammation, possibly through the activation of the Nrf2 pathway.

Isolation and characterization of metabolites produced by endophytes are significant ways to search for novel natural active substances, proving that the endophytes are the unique resources of newer and more effective compounds. Many new compounds with antimicrobial activity from different endophytes have been isolated so far. These new compounds provide alternatives to fight against multi-drug resistance of microorganisms. This review outlined the major achievements and latest developments of endophytes, including the diversity of endophytes and antimicrobial activity of endophytes, as well as its development in China.
