Linxian County in Henan Province, Northern China is known as the region with the highest incidence and mortality rate of esophageal cancer worldwide. Since 1959, the Henan medical team has conducted field work on esophageal cancer prevention and treatment in Linxian. Through three generations of effort exerted by oncologists over 65 years of research on esophageal cancer prevention and treatment in Linxian, the incidence rate of esophageal squamous cell carcinoma in this area has dropped by nearly 50%, and the 5-year survival rate has increased to 40%, reaching the international leading level. This article aims to summarize the history, present opportunities and new challenges, and explore the experience of esophageal cancer prevention and treatment in Linxian (referred to as the “Linxian experience”), providing reference and guidance to cancer prevention and treatment research in China.

Objective To investigatethe relationship between gastroesophageal reflux disease (GERD) symptoms and clinicopathological characteristics, p53 expression, and survival of Chinese patients with esophageal adenocarcinoma. Methods A total of 3882 patients with esophageal adenocarcinoma, 970 matched patients with esophageal squamous cell carcinoma, and 970 matched patients with gastric cardia adenocarcinoma were included to compare the incidence of GERD symptoms. Patients with esophageal adenocarcinoma were divided into two groups according to the presence and absence of GERD symptoms. The differences in clinicopathological characteristics and p53 expression between the two groups were compared by chi-square test, and the differences in survival between the two groups were compared by landmark analysis. Results The incidence of GERD symptoms increased successively in esophageal squamous cell carcinoma, esophageal adenocarcinoma, and gastric cardia adenocarcinoma. In patients with esophageal adenocarcinoma, the proportions of male, less than 65 years old, lower thoracic tumors, tumors without squamous cell carcinoma, poorly differentiation, early tumors (stage 0-I), and p53-positive tumors in the group with GERD symptoms were higher than those in the group without GERD symptoms; moreover, the long-term survival (≥15 years) was better. Conclusion GERD symptom is an important clinical sign of esophageal adenocarcinoma. It is closely related to specific clinicopathological characteristics, p53 overexpression, and good long-term prognosis.

The comparison between traditional Chinese medicine Jinzhen oral liquid (JZOL) and Western medicine in treating children with acute bronchitis (AB) showed encouraging outcomes. This trial evaluated the efficacy and safety of the JZOL for improving cough and expectoration in children with AB. 480 children were randomly assigned to take JZOL or ambroxol hydrochloride and clenbuterol hydrochloride oral solution for 7 days. The primary outcome was time-to-cough resolution. The median time-to-cough resolution in both groups was 5.0 days and the antitussive onset median time was only 1 day. This randomized controlled trial showed that JZOL was not inferior to cough suppressant and phlegm resolving western medicine in treating cough and sputum and could comprehensively treat respiratory and systemic discomfort symptoms. Combined with clinical trials, the mechanism of JZOL against AB was uncovered by network target analysis, it was found that the pathways in TRP channels like IL-1β/IL1R/TRPV1/TRPA1, NGF/TrkA/TRPV1/TRPA1, and PGE2/EP/PKA/TRPV1/TRPA1 might play important roles. Animal experiments further confirmed that inflammation and the immune regulatory effect of JZOL in the treatment of AB were of vital importance and TRP channels were the key mechanism of action.

Objective:To explore the application effect of remote rehabilitation management in postoperative follow-up of liver transplantation patients.Methods:A total of 92 patients who underwent liver transplantation in the First Affiliated Hospital of Zhengzhou University from March 2020 to July 2021 were selected by the convenient sampling method. They were randomly divided into the control group and the observation group, with 46 cases in each group. The control group received routine out-of-hospital follow-up management, while the observation group received remote rehabilitation follow-up management. The follow-up management period was half a year. The treatment compliance and self-care ability of the two groups were compared before and after intervention.Results:After intervention, the scores of each dimension and the total scores of treatment compliance in two groups were higher than those before intervention, and the differences were statistically significant ( P<0.05) . In addition, the scores of each dimension and the total scores of treatment compliance in the observation group were higher than those in the control group after intervention, and the differences were statistically significant ( P<0.05) . After intervention, the scores of each dimension and the total scores of self-care ability in two groups were higher than those before intervention, and the differences were statistically significant ( P<0.05) . The scores of each dimension and the total scores of self-care ability of the observation group after intervention were higher than those of the control group, and the differences were statistically significant ( P<0.05) . Conclusions:Remote rehabilitation management mode can effectively improve the postoperative treatment compliance and self-care ability of liver transplantation recipients.

As the most basic and widely used invasive nursing activity, intravenous therapy plays an extremely important role in clinical treatment, and its theoretical system and practical techniques have developed rapidly. This study carries out a comprehensive comparative analysis of domestic and foreign intravenous therapy concepts, practice standards, specialist nurse training, vascular access tools, infusion-related technologies, and Pharmacy Intravenous Admixture Services. The purpose of this study is to grasp the international development and innovation level in the field of intravenous therapy and the current gap in China, so as to provide a complete reference for the professional construction of intravenous therapy and nursing in China.

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.
