Objective To investigate the effect of Yiqi Huoxue Huatan Decoction(YHHD) on gene expression of vascular endothelial growth factor(VEGF), intercellular adhesion molecule 1(ICAM-1) in the colonic mucosa of ulcerative colitis rats. Methods Sixty rats were divided into six groups, namely normal control group, model control group, low-, middle- and high-dose Y HHD group(gastric gavage of YHHD in the dosage of 13, 26, 52 g·kg-1·d-1 respectively) , and Mesalazine(0.5 g·kg-1·d-1 ) group. T he rat model of ulcerative colitis was established by enema with 2, 4, 6-trinitrobenzene sulfonic acid(TNBS)mixture(2.5%TNBS and 50% ethanol). The changes in rat body weight were monitored. After treatment, pathological features of the colonic mucosa were observed under light microscope, and VEGF and ICAM-1 gene expression levels in the colonic mucosa were measured by reverse t ranscripti on polymerase chai n reaction(RT-PCR). Results Body weight was lighter, and relative gene expression levels of VEGF and ICAM-1 in the model group were significantly higher than those in the normal control group, and pathological features of the colonic mucosa was obvious, the differences being significant between the two groups(P<0.01). Compared with the model group, body weight was increased , pathological features of the colonic mucosa were relieved, and relative gene expression levels of VEGF and ICAM-1 were significantly decreased in YHHD groups(P<0.01), and high-dose YHHD showed the strongest effect. Conclusion YHHD can down-regulate the gene expression of VEGF and ICAM-1, which may be one of its therapeutic mechanisms for ulcerative colitis.

In order to understand the knowledge, attitude and practice (KAP) of vaccination against influenza, pneumonia, human papillomavirus (HPV), herpes zoster (HZ), COVID-19, and hepatitis B among staff of vaccination units in Shandong Province, a sample survey was conducted among 797 staffs of adult vaccination units in 12 counties (cities and districts) of Shandong Province from August to September 2022. The results showed that the respondents had the highest total score of knowledge and attitude for the COVID-19 vaccine, with the M ( Q1, Q3) of 23 (20, 25) and 10 (10, 10), respectively, and had the lowest score of knowledge and attitude for the herpes zoster vaccine, with the M ( Q1, Q3) of 19 (15, 22) and 8 (8, 10), respectively. The vaccine-related knowledge point"vaccine applicable population"had the highest score, with the M (Q1, Q3) of 26 (23, 30). The "contraindications/adverse reactions" and "adverse reaction management" had the lowest score, with the M (Q1, Q3) of 24 (20, 29) and 24 (20, 28), respectively. About 89.71% of respondents received one adult vaccine within two years at least. The principal driver for vaccination of 53.58% of recipients was their understanding of vaccines, which was"it was necessary to receive the vaccine". About 66.00% of respondents who had not received any adult vaccine in the past two years had insufficient awareness of the necessity of vaccination and believed that they were in good health and did not need to receive it. In summary, the staff of adult vaccination units in Shandong Province have a poor understanding of the herpes zoster vaccine in terms of vaccines and a relatively poor understanding of"contraindications/adverse reaction and management"in adult vaccination knowledge points.

Stroke is a brain injury caused by sudden rupture or blockage of blood vessels in the brain, with different types and varying degrees death in cellular level. And there is currently no effective treatment for it. Ferroptosis is a new type of cell death discovered in recent years that is related to factors such as lipid peroxides, reactive oxygen species (ROS), and Fe

Objective    To investigate the clinical value of multidisclplinary team (MDT) in the application of non-small cell lung cancer (NSCLC). Methods    We retrospectively analyzed the postoperative clinical data of 80 patients with NSCLC in the First Hospital of Lanzhou University between January 2014 and May 2018. There were 56 males, 24 females at age of 59±10 years. Forty five patients were performed lobectomy with conventional model, 35 patients were also performed lobectomy after MDT discussion. The clinical effect of the two groups was compared. Results    Compared to conventional model, MDT can shorten operation time, intraoperative blood loss, postoperative chest drainage, catheterization time, complications, length of stay and hospital costs. But there was no significant difference in intraoperative transthoracotomy proportion, delayed wound healing and postoperative pulmonary leakage between the two groups. Conclusion    The efficacy of MDT in the surgical treatment of NSCLC is satisfactory. The MDT is valuable during operation, which reduces surgical trauma and accelerate patients’ recovery, and deserves the clinical promotion.

AIM: To compare the pharmacokinetic behavior of a single oral sorafenib tosylate tablets in Chinese healthy subjects under fasting conditions and evaluate the bioequivalence of the test reagent (T) and the reference reagent (R). METHODS: A single-center, randomized, open-labeled, two-agent, three-period, three-sequence (TRR, RTR, RRT), and partially repeated crossover trial design was adopted. The trial was administered once per cycle (0.2 g) under fasting conditions. 36 healthy subjects were randomly divided into 3 groups, each with 12 cases. RESULTS: Thirty-six healthy subjects (9 females, average age 31 years) were enrolled in the trial. The upper limits of the one-sided 95% confidence interval of the pharmacokinetic parameters C

AIM: To explore the promoting effect of 2-APB on skin wound healing in mice and its potential mechanism. METHODS: KM mice were divided into 5 groups: control group, DMSO group, low (50 mg/L), medium (100 mg/L) and high (200 mg/L) concentration 2-APB group. On the back of each mouse's skin use a circular punch about 1 cm on both sides of the midline of the spine to make a skin wound with a diameter of 10 mm and as deep as the fascia. The control group was only wrapped with gauze and no drugs were applied; the DMSO group was applied 1 g DMSO/Vaseline ointment per day; in the 2-APB group, apply 1 g of 2-APB/Vaseline ointment at a corresponding concentration every day. Pictures were taken the next day to observe the healing, and the material was taken on the 21st day, HE staining was used to observe the pathological morphology of the wound and western blot to detect TRPM7, TGF-β, collagen-I and IL-1β expression. RESULTS: Compared with the control group and the DMSO group, different concentrations of 2-APB could significantly promote skin wound healing in mice (P<0.01), but there was no significant difference in wound healing rate between the DMSO group and the control group group. The results of HE staining showed that, compared with the control group group and the DMSO group, 2-APB could increase the collagen content of the wound and the thickness of the dermis (P<0.01), but there was no significant difference between the DMSO group and the control group group. At the same time, 2-APB could also significantly increase the expression of TGF-β and Col-I on the wound, and inhibit the expression of TRPM7 and IL-1β. CONCLUSION: Different concentrations of 2-APB (50, 100 and 200 mg/L) can promote skin wound healing, and its mechanism may be related to the inhibition of TRPM7.
