OBJECTIVE To establish a interview outline design process and quality control evaluation method based on grounded theory, providing ideas for qualitative research interview outline design in medical fields. METHODS A literature review was conducted to understand the current research status; a preliminary interview outline was developed around the research content. The triangulation method, group evaluation, expert review and pre-interview were adopted to execute the interview outline and conduct quality control. The evaluation indicators and target values were formulated (an average score for the overall quality evaluation of all indicators ≥4.5, and an average score for individual indicators ≥4.00) to evaluate the effect of the interview outline. Taking the research on the mechanism of physicians’ prescribing behavior under the background of Diagnosis Related Groups (DRGs) payment as an example, the methodological contents of above interview outline were applied in practical research. RESULTS The interview outline included basic information and interview questions. The interview questions were divided into three parts:influencing factors survey, promoting and hindering factors of standardizing physician prescription behavior, and communication, with a total of 12 questions. After being reviewed by members of the research group, experts review and pre- interview, a total of 9 people participated in the quality control evaluation of the interview outline. The overall evaluation score was 4.94 (>4.50), and the average score of each indicator was greater than 4.00, indicating that the quality of the outline met the requirements for the interview and could be used for the formal interview. CONCLUSIONS The established interview outline design and quality control method based on grounded theory provides ideas for the qualitative research interview outline design in the medical field, and lays the foundation for further using grounded theory to study the influencing factors and mechanisms of physician prescription behavior under the DRG background.

Objective:
To explore the impacts of coal mine dust on lung function in rats, so as to provide the basis for the early prevention and treatment of coal worker's pneumoconiosis.
Methods:
Seventy-two SPF-grade 8-week-old male Sprague-Dawley rats were randomly divided into the coal dust group, the coal-silica dust group, the silica dust group and the control group. The rats in the first three groups of rats were administered 1 mL corresponding dust suspension into the lungs using non-exposure tracheal instillation, while the rats in the control group were administered 1 mL normal saline. Respiratory rate (f), forced vital capacity (FVC), peak expiratory flow (PEF) and dynamic pulmonary compliance (Cdyn) were measured at 1, 3 and 6 months after dust exposure. Lung tissues were collected to measure reactive oxygen species (ROS) and adenosine triphosphate (ATP) levels using corresponding ELISA kits and ATP assay kits, respectively. The relative mRNA expressions of peroxisome proliferators-activated receptor gamma coactivator 1-alpha (PGC-1α) and mitochondrial transcription factor A (TFAM) were detected using real-time fluorescent quantitative polymerase chain reaction assay. The relative protein expressions of PGC-1α and TFAM were detected using Western blotting.
Results:
There was no interaction between dust type and exposure duration on f (P>0.05), but there were interactions on FVC, PEF and Cdyn (all P<0.05). Compared with the control group at 6 months after dust exposure, the f of the rats in the silica dust group were increased, while the FVC and PEF of the rats in the coal-silica dust and silica dust groups were decreased, and Cdyn of the rats in the coal dust, coal-silica dust and silica dust groups were decreased (all P<0.05). There were interactions between dust type and exposure duration on ROS and ATP levels, the relative mRNA and protein expressions of PGC-1α and TFAM (all P<0.05). Compared with the control group at 3 and 6 months after dust exposure, the ROS levels in the rats in the coal dust, coal-silica dust and silica dust groups were increased, while the ATP levels, the relative mRNA and protein expressions of PGC-1α and TFAM were decreased (all P<0.05).
Conclusion
The lung function impairment in rats caused by different types of coal mine dust is related to PGC-1α-mediated mitochondrial biogenesis dysfunction, which leads to increased ROS levels, decreased ATP and TFAM levels.

This paper summarizes Professor ZHAI Shuangqing's clinical experience in using metal and mineral medicines to treat mental disorders. Based on xiang thinking, the symptoms of mental disorders are classified into five categories, depression-xiang, wind-xiang, fire-xiang, phlegm-xiang, and deficiency-xiang, and the mechanisms of disease development are discussed accordingly. Metal and mineral medicines are key treatments for mental disorders, not only having the function of calming the mind but also promoting qi, stabilizing wind, expelling evil, and tonifying. In clinical practice, the emphasis is placed on harmonizing the disease and its symptoms. Based on self-developed prescription formulas, the appropriate metal and mineral medicines are selected according to the properties, flavors, meridian tropism, and actions of the medicines, as well as the xiang patterns of the mental disorder. For example, Attention Deficit Hyperactivity Disorder (ADHD) is treated by Modified Xiehuang Powder (泻黄散) with Sijunzi Decoction (四君子汤) and adding Fulonggan (Testudinis Carapax) and Longgu (Os Draconis). Persistent insomnia is treated by combining a self-developed insomnia formula with Longgu (Os Draconis), Hupo (Succinum), and Cishi (Magnetitum). Obsessive-compulsive disorder (OCD) is treated by combining a self-developed OCD formula with Longchi (Dens Draconis), Qingmengshi (Fluoritum), and Zheshi (Haematitum). Epilepsy is treated by combining an anti-epilepsy decoction with Qingmengshi (Fluoritum), Longchi (Dens Draconis), and Shengtieluo (Ferrum Rudis).

A wealth of prior studies has confirmed that intratumoral microbiota can survive within tumor tissue, thereby promoting or inhibiting tumor growth. With the development of high-throughput sequencing and metabolomics, increasing attention has been paid to the correlation between intratumoral microbiota and host metabolism, and their effect on tumorigenesis and progression. This review focuses on the interaction between intratumoral microbiota and tumor metabolism. It emphasizes the effects of intratumoral microbiota on tumor sugar, lipid, and amino acid metabolism and explores emerging therapeutic strategies for guiding tumor prevention and treatment by modulating tumor metabolism. Although the specific role of intratumoral microbiota in tumor metabolism remains to be further studied, a deepened understanding of the interaction between tumor-specific microbiota and tumor metabolism may provide new directions and application prospects for tumor prevention and treatment.

Objective To explore the potential causality between visceral adipose tissue (VAT) and inflammatory bowel disease, peptic ulcer disease, irritable bowel syndrome and gastroesophageal reflux disease. Methods Two-sample Mendelian randomization (MR) investigations were carried out, employing genetic variants closely linked with VAT as instrumental variables. The summary data for aforementioned gastrointestinal disorders were obtained from the genome-wide association study (GWAS) in UK biobank and Finn Gen databases, respectively. The inverse variance-weighted method (IVW) was employed as the primary analytical method, bolstered by a sequence of sensitivity analyses to verify the robustness of MR. Subsequently, a meta-analysis was conducted to amalgamate the findings derived from both databases. Results This study included a total of 42 single nucleotide polymorphisms that were strongly associated with visceral adipose tissue as instrumental variables. Statistically significant correlations were found between VAT and peptic ulcer (OR=1.17, 95% CI: 1.08-1.27, P < 0.01), gastroesophageal reflux disease (OR=1.10, 95% CI: 1.03-1.18, P = 0.02), and irritable bowel syndrome (OR=1.12, 95% CI: 1.04-1.12, P = 0.03). There was no statistical significance between VAT and inflammatory bowel disease (OR=0.94, 95% CI: 0.79-1.12, P = 0.65). Conclusion VAT exhibits a causal linkage with peptic ulcer, gastroesophageal reflux disease, and irritable bowel syndrome. Accurately assessing VAT levels via imaging methods, screening individuals at high-risk, and actively controlling abdominal obesity bear important clinical significance.

Objective:To evaluate the practical value of the up-converting phosphor technology (UPT) in the field fast detection of plague, and to provide scientific basis for its promotion and application in the field work of plague monitoring.Methods:In September 2020, a total of 116 samples (including 4 samples for epidemic determination) were collected at the plague epidemic site in Menghai County, Yunnan Province, including 24 human blood and lymphatic fluid samples, 83 rat liver and muscle samples, and 9 rat blood samples. In March 2023, a total of 12 rat liver and muscle samples were collected from Lijiang City for on-site monitoring of plague outbreak (all of them were outbreak determination samples). All of the above samples were tested for Yersinia pestis antibody and antigen using the up-converting phosphor technology. At the same time, haemagglutination test, real-time fluorescence quantitative PCR and bacterial culture were conducted to compare the detection process and results of different experimental methods, the advantages and disadvantages of the up-converting phosphor technology for detecting Yersinia pestis were analyzed, and the feasibility of using this detection method in the field of plague epidemic monitoring was judged. Results:The plague epidemic samples site in Menghai County, Yunnan Province were tested by up-converting phosphor technology, and 19 samples were found to be positive for Yersinia pestis (1 antibody-positive and 18 antigen-positive). Among the samples determined, 4 samples with positive results of Yersinia pestis were detected by up-converting phosphor technology, and the results of their haemagglutination test, real-time fluorescence quantitative PCR and bacterial culture were all positive. All samples from Lijiang City were tested by up-converting luminescence technology, two samples were positive for Yersinia pestis(antigen-positive). The results of haemagglutination test and real-time fluorescence quantitative PCR were positive, and one sample was positive for bacterial culture. The time required for up-converting phosphor technology, haemagglutination test, real-time fluorescence quantitative PCR, and bacterial culture were 0.5, 4.0, 2.5 and 72.0 h, respectively. Conclusions:The results of Yersinia pestis detection by up-converting phosphor technology are basically consistent with the results of haemagglutination test, real-time fluorescence quantitative PCR and bacterial culture, but the time used is relatively short. When the number of samples is large, this method can be used preferentially in the field work of plague outbreak monitoring, which can quickly complete the preliminary judgement of plague outbreak, and save a lot of time and economic resources for the next step of plague prevention and control work.
