Objective This study aims to investigate the expression, phenotypic changes, and mechanisms of action of guanylate-binding protein 2 (GBP2) in the process of silica-induced pulmonary fibrosis. Methods The expression and localization of GBP2 in silicotic lung tissue were detected by immunohistochemical staining and immunofluorescence. An in vitro cell model was constructed, and methods such as Western blot and real-time quantitative reverse transcription polymerasechain reaction were utilized to investigate the function of GBP2 in different cell lines following silica stimulation. The mechanism of action of GBP2 in various cell lines was elucidated using Western blot analysis. Results GBP2 was highly expressed in the lung tissue of patients with silicosis. Immunohistochemical staining and immunofluorescence have revealed that GBP2 was localized in macrophages and epithelial cells. In vitro cell experiments demonstrated that silicon dioxide stimulated THP-1 cells to activate the c-Jun pathway through GBP2, promoting the secretion of inflammatory factors and facilitating the occurrence of M2 macrophage polarization. In epithelial cells, GBP2 promoted the occurrence of epithelial to mesenchymal transition (EMT) by upregulating Krueppel-like factor 8 (KLF8). Conclusion GBP2 not only activates c-Jun in macrophages to promote the production of inflammatory factors and the occurrence of M2 macrophage polarization, but also activates the transcription factor KLF8 in epithelial cells to induce EMT, collectively promoting the progression of silicosis.

Disorders of gastrointestinal motility (DGIM) are very common diseases in the department of gastroenterology and the prevalence is increasing gradually. The pathogenesis of DGIM is complex and closely related to Cajal interstitial cells of gastrointestinal tract, brain-intestinal axis and intestinal microecology. So far, a variety of diagnostic techniques have emerged, including esophageal 24 h pH monitoring and impedance analysis, electrogastrography, radionuclide scanning, ultrasound, 13C gastric emptying breath test, hydrogen breath test, defecation contrast, X-ray marker method, high resolution manometry and wireless motility capsules. According to the different pathogenesis of DGIM, treatment methods emerge in an endless stream, such as adjustment of lifestyle, drugs and surgical treatment and so on. Individual treatment should be provided clinically for different patients.

Objective:To investigate the epidemiology of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in patients with maintenance hemodialysis (MHD) in Jiangsu province during SARS-CoV-2 pandemic in China from December 7, 2022 to January 27, 2023, and to analyze the influencing factors of all-cause death.Methods:It was a multi-center cross-sectional investigation. Structured questionnaire was used to collect patient information by medical staff of each hemodialysis center (room) as investigators. Part of the demography data and laboratory examination data came from the Jiangsu Province Hemodialysis Data Information System. MHD patients from hemodialysis centers (rooms) at all levels of medical institutions and independent hemodialysis institutions in Jiangsu province during the outbreak of SARS-CoV-2 infection were included, and the clinical characteristics and all-cause mortality of confirmed and suspected cases of SARS-CoV-2 infection were analyzed.Results:Questionnaire surveys and data analysis on 57 278 patients in 407 hemodialysis centers (rooms) were completed, accounting for 90.41% of the total number of MHD patients (63 357 cases) in Jiangsu province during the same period. There were 24 038 cases (41.97%) of SARS-CoV-2 infection and 14 805 cases (25.85%) of suspected infection, which were widely distributed in all dialysis centers in Jiangsu province. After clinical classification of 38 843 confirmed and suspected SARS-CoV-2 infection cases, 3 662 cases were severe and critical cases, accounting for 9.43% of the infected and suspected cases. Among the patients who had completed the questionnaires, there were 1 812 all-cause deaths, with an all-cause mortality rate of 3.16%. Multivariate logistic regression analysis showed that elderly (taking ≤50 years as a reference, 51-59 years: OR=1.583, 95% CI 1.279-1.933, P=0.001; 60-69 years: OR=3.972, 95% CI 3.271-4.858, P<0.001; 70-79 years: OR=7.236, 95% CI 5.917-8.698, P<0.001; ≥80 years: OR=11.738, 95% CI 9.459-14.663, P<0.001), male ( OR=1.371, 95% CI 1.229-1.529, P<0.001), and co-infection with hepatitis B virus (HBV) (positive serum HBV surface antigen, OR=0.629, 95% CI 0.484-0.817, P<0.001) were independent influencing factors for all cause mortality. Receiver-operating characteristic curve analysis showed that the area under the curve for male, age and current HBV infection prediction of all-cause death was 0.529 ( P<0.001), 0.724 ( P<0.001) and 0.514 ( P=0.042), respectively, and the cut-off value for age prediction of all-cause death was 65.5 years old. Compared with patients without HBV infection, MHD patients with HBV infection significantly reduced the proportion of severe and critically ill patients, all-cause hospitalizations and all cause deaths when infected with SARS-CoV-2 (4.99% vs. 6.41%, χ2=6.136, P=0.013; 8.90% vs. 11.44%, χ2=11.662, P<0.001; 2.01% vs. 3.37%, χ2=10.713, P=0.001, respectively). Conclusion:The MHD patients in Jiangsu province are susceptible to SARS-CoV-2. Elderly age and male gender are independent risk factors for death in MHD patients during the epidemic, while the HBV infection may be a protective factor for death of MHD patients infected with SARS-CoV-2.

【Objective】 To analyze the comprehensive factors causing adverse reactions to apheresis platelet donation(ARAPD), so as to provide references for effective prevention of ARAPD. 【Methods】 The 272 cases of ARAPD from 2012 to 2019 in Lanzhou were statistically analyzed, and factors that induced ARAPD were studied. Statistical analysis were performed according to the gender, nationality, occupation, age, weight, donation units, and number of donations. 【Results】 As to the factors inducing ARAPD, anticoagulant reactions accounted for the first(32.4%, 88/272). Women and students were prone to develop ARAPD. Among all age groups, 18~25 years old were most likely to develop ARAPD(53.68%, 10 572/35 265). The incidence of ARAPD were significantly different by ages and weights(P<0.05), and donors with lighter weight were more prone to develop ARAPD(P<0.05). The incidence of ARAPD were also significantly different between first-time and repeated donors(P<0.05), but not among the donation units. 【Conclusion】 The anticoagulant reactions are the leading reason for ARAPD. For female, student, young, light-weight, and first-time blood donors, special attention should be paid and corresponding interventions taken to them.

【Objective】 To study the current situation of apheresis platelets collection in various regions of Gansu province by comparing and analyzing relevant data from blood stations in 14 prefecture-level cities of Gansu province. 【Methods】 The units of collected platelets and rate of double-dose collection in 13 regional blood stations and 1 provincial blood center from 2016 to 2020, as well as the clinical supply and demand was statistically analyzed. 【Results】 From 2016 to 2020, the total units of platelets collected by 13 blood stations and 1 blood center in Gansu increased from 11 255 U to 15 270 U, with the increase rate at 35.7% in 5 years, and mainly were collected by the provincial blood center (74.57%, 50 253/ 67 392). Although the rate of double-dose collection in the province showed a steady upward trend, only 3 blood stations realized annual double-dose collection more than 20%. There was still a gap of about 10% between supply and clinical needs. 【Conclusion】 Although the number of platelet collections and units in each blood station in Gansu is on the rise in general, the units collected varies in each blood station. Therefore, further measures need to be taken from the aspects of publicity, recruitment, optimizing the collection process, improving the rate of double-dose collection, retention of regular blood donors and regional coordination to increase the collection units, narrow down the regional gap and ensure the balance between supply and demand.

There are a large number of atypical symptoms and undifferentiated diseases in general practice, in which sociological factors are deeply involved. So to incorporate social factors into clinical thinking and to interpret disease from the perspective of the patient′s social life will enrich the multidisciplinary medical model and holistic care in general practice. This article shares author′s clinical experience through introducing typical cases, in which the patient′s social life and behavior characteristics played certain roles in disease development. The article also explores a new way from the sociological perspectives to interpret the complex symptoms that are difficult to be explained clinically by biomedicine or psychology.
