Objective To explore the relationship between health literacy of chronic diseases and the effect of blood glucose control in newly diagnosed and prediabetes patients. Methods A total of 180 newly diagnosed and prediabetes patients treated in the Western Theater Command General Hospital from January 2021 to January 2023 were selected, including 94 newly diagnosed and 86 prediabetes patients. The health literacy of chronic diseases in these patients was evaluated by using the health literacy management scale (HeLMS) developed by Jordan et al. The differences of clinical general information and blood glucose control between patients with adequate and insufficient health literacy were analyzed. Results Among the 180 patients, the total score of information acquisition ability, communication and interaction ability, willingness to improve health, willingness for financial support, total score of health literacy, and adequate proportion of health literacy assessed by HeLMS were (35.54 ± 7.21), (33.02 ± 8.15), (15.54 ± 3.92), (7.10 ± 0.98), (91.87 ± 7.28), and 51.67%, respectively. The age of patients with adequate health literacy in the newly diagnosed diabetes group was (52.23 ± 7.15) years old, which was significantly lower than that of patients with insufficient health literacy (P<0.05). The proportions of patients with high school education and above, monthly income ≥ 3000 yuan, and relatives engaged in medical work were 68.09%, 68.09%, and 34.04%, respectively, which were significantly higher than those of patients with insufficient health literacy (P<0.05). The age of patients with adequate health literacy in prediabetes group was (82.23 ± 4.15) years old, which was significantly lower than that of patients with insufficient health literacy (P<0.05). The proportions of patients with high school education and above, monthly income ≥ 3000 yuan, number of children ≥ 2, and relatives engaged in medical work were 65.22%, 67.39%, 34.78%, and 41.30%, respectively, which were significantly higher than those of patients with insufficient health literacy (P<0.05). The fasting blood glucose, glycosylated hemoglobin and 2h postprandial blood glucose of patients with adequate health literacy in the newly diagnosed diabetes group after treatment were (6.43 ± 0.93) mmol/L, (6.02 ± 0.91)% and (7.71 ± 1.01) mmol/L, respectively, which were significantly lower than those of patients with insufficient health literacy (P<0.05). The fasting blood glucose, glycosylated hemoglobin and 2h postprandial blood glucose in patients with adequate health literacy in prediabetes group after treatment were (5.21 ± 0.37) mmol/L, (5.20 ± 0.40)% and (6.20 ± 0.92) mmol/L, respectively, which were significantly lower than those in patients with insufficient health literacy (P<0.05). Conclusion The chronic disease health literacy of prediabetes and new-onset patients is related to the age, education and monthly income level, number of children, relatives engaged in medical work of patients, and the level of health literacy is helpful to the control of blood glucose.

Objective:To explore the mediating role of mentoring function between proactive personality and transition shock in new nurses, with the aim of providing reference and basis for managers to develop effective intervention measures for new nurses during their transformational period.Methods:Convenience sampling method was used to select 280 new nurses from the Second Affiliated Hospital of Zhejiang University School of Medicine, and a cross-sectional survey was conducted by applying the General Information Questionnaire, Transition Shock Scale, Proactive Personality Scale, and Mentoring Function Scale. The mediating role of mentoring function between new nurses′ proactive personality and transition shock was evaluated by constructing structural equation modelling.Results:265 valid questionnaires were ultimately collected. Among 265 nurses, there were 25 males and 240 females, with an age of (22.88 ± 2.12) years. The score of transition shock, proactive personality, and mentoring function of new nurses were (83.45 ± 18.95), (58.66 ± 9.96) and (81.72 ± 14.46) respectively; transition shock was negatively correlated with proactive personality and mentoring function ( r=-0.379, -0.340, both P<0.01), and proactive personality was positively correlated with mentoring function ( r=0.452, P<0.01); the mediating effect of mentoring function between proactive personality and transition shock was significant (95% CI -0.085 - -0.015, P<0.01), accounting for 29.14% of the total effect. Conclusions:New nurses' transition shock is at a moderately high level, and proactive personality can affect transition shock directly or indirectly through mentoring function. Managers can mitigate new nurses′ transition shock by improving the quality of mentoring.

Bovine leukemia virus(BLV)mainly causes bovine B-cell malignant lymphoma,which causes immunosuppression and leads animals susceptible to other diseases.BLV has been detected all over the world except in Western Europe.Antibodies to BLV have been detected in humans,and reverse transcribed DNA of BLV were detected in breast tissue sections and lung tumors,which in-dicate that BLV is a potential zoonotic disease.At present,there are no effective treatment methods or commercial vaccines for BLV.An in-depth understanding of the development of BLV detection technology will help researchers choose suitable detection methods,avoid invalid detection results,and meet the requirements of disease prevention and control.In view of this,this paper reviews 19 detection technologies of BLV including cytology detection,nucleic acid detection,and serology de-tection.The advantages,disadvantages,and scope of application were also analyzed,which provide theoretical guidance for the prevention and control of bovine leukemia.

Objective To discuss the clinical diagnosis and treatment value of double-balloon enteroscopy for small intestinal bleeding diseases.Methods Retrospective collection of clinical data from 87 patients who underwent double-balloon enteroscopy for small bowel bleeding in Shantou Central Hospital from August 2019 to May 2023,and analysis of the diagnosis and treatment of small bowel bleeding causes by double-balloon enteroscopy.Results Totally 87 cases of small intestinal bleeding patients underwent a total of 117 double-balloon enteroscopy examinations,with 29 performed orally and 28 performed anally,and 30 cases simultaneously underwent both oral and anal bilateral enteroscopy examinations,with the depth of oral examination greater than that of anal examination,and the duration of oral examination shorter than that of anal examination.Among them,with a diagnostic rate of double-balloon enteroscopy at 83.91％and a pathological diagnostic accuracy rate at 83.78％.Small intestinal tumors were the main cause of small intestinal bleeding in this study,with gastrointestinal stromal tumors being the most common pathological type among small intestinal tumors.The frequency of occurrence for small intestinal tumors in individuals over 40 years old was higher than those under or equal to 40 years old group,showing statistical significance.Crohn's disease occurred more frequently in the ileum compared to jejunum,and its frequency was higher in individuals under or equal to 40 years old compared to those over 40 years old group,both differences were statistically significant(P＜0.05).A total of cases of small intestinal bleeding patients successfully underwent endoscopic hemostasis via double-balloon enteroscopy without any complications such as gastrointestinal perforation or severe bleeding during surgery.Conclusion Double balloon enteroscopy has a high diagnostic value for small intestinal bleeding and can provide basis for clinical treatment.

Objective:To detect the expression of ARK5 in peripheral blood circulating tumor cells (CTCs) from pancreatic cancer patients and explore its correlation with the efficacy and prognosis for gemcitabine chemotherapy.Methods:A total of 175 peripheral blood samples of pancreatic cancer patients who were treated in the Department of Hepatobiliary Surgery, Second Affiliated Hospital of Jiaxing University from January 2016 to June 2021 were collected. CTCs were enriched by nano-microfluidic chip technology. The expression of ARK5 in CTCs was detected by immunofluorescence. According to the expression of ARK5, the patients were divided into two groups: positive group and negative group. The differences on clinicopathological features, the efficacy of chemotherapy, median survival and progression-free survival time between the two groups were compared.Results:CTCs were enriched in 98 of 175 patients (55.6%), including 70 ARK5 positive and 28 ARK5 negative patients. There were no significant differences on clinical features between the two groups, and the two groups were comparable. In the 70 ARK5 positive patients, 64 patients (91.4%) were resistant to gemcitabine, while only 12 of the 28 ARK5 negative patients (42.8%) were resistant to gemcitabine. The incidence of gemcitabine resistance in ARK5 positive patients was significantly higher than that in ARK5 negative patients, and the difference was statistically significant ( P<0.001). The median survival time was 11.5 months in ARK5 positive group and 14 months in ARK5 negative expression group, and the progression-free survival time was 6 months in ARK5 positive expression group and 8 months in negative expression group. The survival time of ARK5 positive group was significantly shorter than that of ARK5 negative group, and the difference was statistically significant ( P<0.05). Conclusions:The pancreatic cancer patients with ARK5 positive CTCs have significantly higher incidence of gemcitabine resistance and shorter survival time than those with ARK5 negative CTCs. Detection of ARK5 expression in CTCs may be a new method to judge chemotherapy efficacy and prognosis for pancreatic cancer patients.

Background and purpose: Long non-coding RNA small nucleolar RNA host gene 5 (lncRNA SNHG5) plays a cancer-promoting role in many cancers, however its effect on colorectal cancer (CRC) and its regulatory mechanism are not clear. This study aimed to explore the mechanism of lncRNA SNHG5/miR-26a-5p/metadherin (MTDH) signal axis promoting metastasis of CRC. Methods: The data of The Cancer Genome Atlas (TCGA) database was analyzed, the abnormal expression of lncRNA in CRC was explored and analyzed the survival. Samples of CRC, paracancerous tissues and complete clinical data of patients who underwent surgical resection from October 2020 to October 2021 were collected. The expression levels of SNHG5 and miR-26a-5p in lncRNA were detected by real-time fluorescence quantitative polymerase chain reaction (RTFQ-PCR), and the expression level of MTDH was detected by immunohistochemistry. The relationship between the relative expression level of lncRNA SNHG5 in CRC and clinicopathological features and survival time was analyzed. The effects of lncRNA SNHG5 on the proliferation, migration and invasion of CRC cells were detected by cell counting kit-8 (CCK-8), clone formation, scratching assays, transwell test and in vivo xenotransplantation. The relationship between CRC cell metastasis, the expression level of epithelial-mesenchymal transition related molecules and lncRNA SNHG5 expression level by Western blot and immunohistochemical detection were explored. The physical interaction between SNHG5 and miR-26a-5p, MTDH and miR-26a-5p was studied by RNA pull-down test, double luciferase reporter gene detection and RNA co-immunoprecipitation. The functional relationship among the three was verified by CCK-8, EdU and transwell experiments. The effect of SNHG5, miR-26a-5p and MTDH expression on migration and invasion related molecules was analyzed by Western blot. Results: The results of TCGA database analysis showed that lncRNA SNHG5 was significantly upregulated in CRC. The results of RTFQ-PCR and immunohistochemistry showed that the levels of lncRNA SNHG5 and MTDH in CRC tissues were significantly upregulated (P＜0.05), the level of miR-26a-5p was decreased (P＜0.05), and the level of MTDH in samples with high expression of SNHG5 was also increased. The expression of lncRNA SNHG5 in CRC tissues with serosa and extraserosal invasion, distant metastasis, lymph node metastasis and TNM stage Ⅲ was significantly higher compared with subserosal invasion, no distant metastasis and lymph node metastasis and TNM stage Ⅰ-Ⅱ (P＜0.05). The results of survival analysis showed that the high expression of lncRNA SNHG5 was significantly correlated with overall survival rate (P＜0.05). Overexpression of lncRNA SNHG5 could enhance the proliferation, clone formation, migration and invasion of CRC cells, promote the growth and lung metastasis of transplanted tumor, increase the relative expression level of Ki-67 proliferation index and vimentin (P＜0.05), and decrease the relative expression level of E-cadherin (P＜0.05). However, the development of CRC cells was inhibited after inhibition of lncRNA SNHG5 expression. RNA pull-down test, double luciferase reporter gene detection and RNA co-immunoprecipitation confirmed the physical interaction between SNHG5 and miR-26a-5p, MTDH and miR-26a-5p. Upregulation of miR-26a-5p or downregulation of MTDH expression in lncRNA SNHG5 overexpressed cells partially reversed the effects of lncRNA SNHG5 on proliferation, migration, invasion and expression of related molecules in CRC cells. Conclusion: LncRNA SNHG5 is upregulated in CRC tissues and cells, and its high expression is related to tumor progression and poor survival. It can be used as a molecular sponge of miR-26a-5p to regulate the expression of MTDH to promote the proliferation and metastasis of SW620 cells.

BACKGROUND: The switch/sucrose nonfermentable chromatin-remodeling (SWI/SNF) complex is a pivotal chromatin remodeling complex, and the genomic alterations (GAs) of the SWI/SNF complex are observed in several cancer types, correlating with multiple biological features of tumor cells. However, their role in liver metastasis of non-small cell lung cancer (NSCLC) remains unclear. Our study aims to investigate the role and potential mechanisms underlying NSCLC liver metastasis induced by the GAs of SWI/SNF complex. METHODS: The GAs of SWI/SNF complex in NSCLC cell lines (H1299, H23 and H460) were identified by whole-exome sequencing (WES). ARID1A knockout H1299 cell was constructed with the CRISPR/Cas9 technology. The mouse model of liver metastasis from NSCLC was established to simulate lung cancer liver metastasis and observe the metastasis rate under different gene mutation conditions. RNA sequencing and Western blot were conducted for differential gene expression analysis. Immunohistochemistry (IHC) analysis was used to assess protein expression levels of SWI/SNF-regulated target molecules in mouse liver metastases. RESULTS: WES analysis revealed intracellular gene mutations. The animal experiments demonstrated a correlation between the GAs of SWI/SNF complex and a higher liver metastasis rate in immunodeficient mice. Transcriptome sequencing and Western blot analysis showed upregulated expression of ALDH1A1 and APOBEC3B in SWI/SNF-mut cells, particularly in ARID1A-deficient H460 and H1299 sgARID1A cells. IHC staining of mouse liver metastases further demonstrated elevated expression of ALDH1A1 in the H460 and H1299 sgARID1A group. CONCLUSIONS This study underscores the critical role of the GAs of SWI/SNF complex, such as ARID1A and SMARCA4, in promoting liver metastasis of lung cancer cells. The GAs of SWI/SNF complex may promote liver-specific metastasis by upregulating ALDH1A1 and APOBEC3B expression, providing novel insights into the molecular mechanisms underlying lung cancer liver metastasis.

Objective:To analyze general information, diagnosis and treatment of digestive endoscopy departments in county-level hospitals of Yunnan Province, thus to provide evidence for improving the endoscopic diagnosis and therapy in these hospitals.Methods:An online survey was performed to collect quality-related information of digestive endoscopy centers (departments) at county-level hospitals of Yunnan from January 2019 to January 2020, including endoscopic equipment, endoscopic techniques, staffing, number of operations, and quality control.Results:A total of 143 county-level hospitals were involved in this study. Each hospital owned only 1.74 endoscopy operation rooms on average, 1.42 regular endoscopy workstation, 4 endoscopes. There were only 10 endoscopic ultrasonography workstations and 2 enteroscopy workstations respectively installed in these hospitals. Endoscopic retrograde cholangiopancreatography was independently performed in only 4 hospitals. There were 392 professional endoscopists in all 143 hospitals, 18.62% (73/392) of whom were able to perform endoscopic therapy of grade 4, while only 6.12% (24/392) of whom could perform endoscopic submucosal dissection (ESD) independently. In 2019, the early diagnostic rate of gastrointestinal tract cancer in these hospitals was 19.48% (1 133/5 817). The early diagnostic rate was 21.04% (276/1 312) for esophageal cancer, 19.53% (397/2 033) for gastric cancer, and 18.61% (460/2 472) for colorectal cancer. The colorectal adenoma detection rate was 12.83% (12 207/95 148). The rate of reaching cecum during colonoscopy was 70.49% (67 067/95 148). The complete resection rate of ESD was 12.54% (221/1 763).Conclusion:The general situation of digestive endoscopy in county-level hospitals of Yunnan is far from being well-developed, which may be attributed to slow upgrading of equipments, inadequate training of endoscopic professionals and undemanding quality control. It is highly significant to improve medical service and quality of diagnosis and treatment of digestive endoscopy in these hospitals, on the basis of a complete endoscopy quality control system with a high standard.

Objective:To investigate difficult-to-treat sites in patients with psoriasis receiving biological therapy.Methods:Clinical data were retrospectively collected from 73 adult patients with psoriasis in the database of Psoriasis Center, National Clinical Research Center for Skin and Immune Diseases from June 2020 to September 2021, who had received sufficient and standardized treatment with biological agents for ≥ 24 weeks, and were still treated with biological agents at the time of enrolment into this study with the psoriasis area and severity index (PASI) score being 1 - 5 at the time of enrolment into the database of Psoriasis Center. Distribution of psoriatic lesions resistant to biological therapy were analyzed, and differences in refractory sites were compared between different biologics. Chi-square test or Fisher′s exact test was used to analyze differences in the anatomical distribution of residual skin lesions after treatment with different biologics, McNemar test to compare the anatomical distribution of skin lesions before and after biological therapy, and Kruskal-Wallis H test to analyze the association between PASI scores for residual skin lesions and dermatology life quality index (DLQI) scores. Results:After ≥ 24 weeks of sufficient and standardized biological therapy in the 73 patients, refractory skin lesions mostly involved the lower limbs (46 cases, 63.01%) , followed by the scalp (36 cases, 49.32%) and upper limbs (27 cases, 36.99%) ; proportions of patients with residual skin lesions on the face and neck, trunk, upper limbs, lower limbs, hands and feet significantly decreased after biological therapy compared with those before treatment (paired χ2 = 5.14, 7.69, 9.90, 4.17 and 6.13, P = 0.016, 0.003, 0.001, 0.031 and 0.008, respectively) , while there was no significant difference in the proportions of patients with skin lesions on the scalp and genital areas before and after treatment (both P > 0.05) . No significant difference in the anatomical distribution of residual skin lesions was observed between the 13 patients receiving treatment with tumor necrosis factor inhibitors (adalimumab, infliximab, or tumor necrosis factor receptor-antibody fusion protein) and 59 receiving treatment with interleukin-17 (IL-17) inhibitors (secukinumab or ixekizumab) (all P > 0.05) . There was no significant difference in the anatomical distribution of residual skin lesions in the 13 patients before and after the treatment with tumor necrosis factor inhibitors (all P > 0.05) ; in the 59 patients treated with IL-17 inhibitors, the proportions of patients with residual skin lesions on the trunk, upper limbs, hands and feet significantly decreased after treatment (paired χ2 = 4.90, 9.09 and 7.11, P = 0.021, 0.001 and 0.004, respectively) , while there was no significant difference in the distribution of skin lesions on the scalp, face and neck, lower limbs and genital area before and after treatment (all P > 0.05) . Among the 73 patients, the PASI scores for lesions on the upper and lower limbs and the total PASI scores were all associated with the DLQI scores ( H = 7.52, 12.61, 6.75, respectively, all P < 0.05) , and were significantly higher in the patients with DLQI scores of > 10 points than in those with DLQI scores of ≤ 5 points (all P < 0.05) . Conclusions:Biological therapy-resistant psoriatic lesions were mostly located on the scalp, and refractory skin lesions mostly involved the lower limbs, scalp and upper limbs. No significant difference in the anatomical distribution of residual skin lesions was observed between patients treated with tumor necrosis factor inhibitors and IL-17 inhibitors, but IL-17 inhibitors may result in lesion clearance at more anatomical sites compared with tumor necrosis factor inhibitors.

Objective:To study the effect of Helicobacter pylori (HP) infection on the standardized dose of postoperative thyrotropin suppression of differentiated thyroid carcinoma.Methods:A total of 82 patients diagnosed with differentiated thyroid carcinoma and receiving total thyroidectomy in Beijing Rehabilitation Hospital affiliated to Capital Medical University from Jan. 2019 to Jun. 2020 were enrolled in this study prospectively.19 patients with higher standardized dose of the thyrotropin suppression (>2.5 μg·kg -1·d -1) were selected as the experimental group, and 63 patients with the lower standardized dose of the thyrotropin suppression (≤2.5 μg·kg -1·d -1) were selected as the control group. The presence of HP infection was measured by C13 method, and the HP infection rate was compared between the two groups. The patients with HP infection in the experimental group received standard quadruple therapy to eradicate Helicobacter pylori. The standardized dose before and after treatment were observed and compared. Results:The HP infection rate in the experimental group (73.7%, 14/19) were significantly higher ( P<0.05) than those in the control group (31.7%, 20/63). In the experimental group, 14 patients with HP infection in the experimental group received standard quadruple therapy to eradicate HP. HP was successfully eradicated in 11 patients after the treatment (one patient quit the treatment before completion, the actual eradication rate was 84.6%) ; Eight weeks after the treatment, the dose adjustment of thyrotropin suppression reached steady-state in 13 patients completed the therapy. The average standardized dose was (2.15±0.25) μg·kg -1·d -1, significantly lower than that before treatment [ (2.89±0.21) μg·kg -1·d -1] ( P<0.05) . Conclusions:HP infection may be an important factor affecting the standardized dose of thyrotropin suppression in postoperative patients with thyroid cancer. For those patients with HP infection, eradication treatment of HP can significantly reduce the standardized dose and treatment-related complications.
