As the medical health service is closely related to health of general public,making harmonious hospital inevitably becomes an important link in constructing a harmonious society.The mutual trust is the most fundamental and active factor in physician-patient relationship.Therefore,construction of a harmonious hospital in the new situation should embark from the hospital connotation construction in great details to reconstruct a harmonious medical relation with mutual trust between doctors and patients.

The nitrate-N content in KNO3 solution and soil was rapidly predicted using techniques of mid-infrared spectroscopy, in which 15 NO-3 and 14 NO-3 were distinguished and predicted. The results showed that the characteristic band of nitrate in solution and soil was 1200-1500 cm-1 , and compared with 14 NO-3 , the red shift of characteristic band of 15 NO-3 was about 35 cm-1 . In the characteristic band of nitrate, absorption band increased with the nitrate nitrogen concentration with less interference absorption. The linear regression was made between the first principal component of characteristic band and nitrate-N content, and correlation coefficient was more than 0 . 9840 , indicating that the technique of mid-infrared attenuated total reflectance spectroscopy could be applied for rapid monitoring of nitrate in solution and soil. Meanwhile, based on the red shift characteristic of 15 NO-3 absorption band, the method of partial least squares were involved to predict the nitrate-N of different N-isotope labeled in solution and soil, resulting that all the prediction models reached excellent levels. For 14 NO3-N and 15 NO3-N in solution, the correlation coefficients ( R2 ) were 0. 9980 and 0. 9982 respectively, and ration performance to standard deviations ( RPD ) were 6. 44 and 4. 76, respectively. While for 14 NO3-N and 15 NO3-N in soil, the correlation coefficients ( R2 ) were 0. 9794 and 0. 9679, and RPD were 5. 75 and 4. 78, respectively. Therefore, the technique of mid-infrared attenuated total reflectance spectroscopy can be applied for rapid monitoring different N-isotope labeled nitrate in solution and soil, to provide a new in situ and fast time method to study nitrification process in soil.

Objective To investigate the state of perceived discrimination,mental health knowledge and self-discrimination of the public,and analyze the relationship among these variables,and explore the mediating effect of mental health knowledge between the perceived discrimination and self-discrimination.Methods A total of 1 088 residents in Guangzhou City were assessed with the Perceived Devaluation-Discrimination Scale (PDDS),Attitudes about Mental Illness Associated Stigma Scale-Chinese Version (AMIASS-C) and Mental Heahh Knowledge Questionnaire (MHKQ).Results The average score of PDDS was 2.63±0.35.The rate of mental health knowledge was 72.4％(788/1 088) and the score of AMIASS-C was 2.58±0.45.The perceived discrimination,mental health knowledge and self-discrimination were significantly correlated with each other,r=0.320,-0.240,P＜0.01.The mental health knowledge played a negative mediating role between perceived discrimination and self-discrimination.Conclusions The mental health knowledge was a mediator between perceived discrimination and self-discrimination.

The most common metastatic site of prostate cancer is the bone, followed by the lung, bladder, liver, and adrenal gland. We report on a rare case of pancreatic metastasis from prostate cancer. A 52-year-old patient was admitted to the hospital with epigastric pain for 20 days. PET-CT showed malignant lesions in the prostate and pancreas, and prostate and pancreas puncture biopsies were performed, respectively. The patient was diagnosed as prostate cancer with pancreatic metastasis according to the pathological findings. After undergoing androgen deprivation therapy and docetaxel chemotherapy for 6 cycles, reexamination revealed that the pancreatic metastases had disappeared.

Objective To detect the expression levels of high mobility group box chromosomal protein 1 (HMGB1) and Th17 cells transcription factors, related cytokines in peripheral blood of rheumatoid arthritis (RA) patients and analyze the relations between HMGB1 and CRP, ESR, RF in RA patients. The other aim of this study is to identify the expression level of HMGBI and the relationship between HMGB1 and Th17 in RA patients. Methods The mRNA levels of HMGB1, RORyt, interleukin (IL)-17 in the peripheral blood mononuclear cells (PBMC) were determined by quantitative real-time PCR (QRT-PCR) from 80 patients with rheumatoid arthritis,including 32 RA patients in stable phase and 48 patients in active phase, and 50 healthy volunteers. The concentration of HMGB1, IL-23, IL-17 in plasma were detected by enzyme linked immunosorbent assay (ELISA), one-way ANOVA and Spearman's correleation were adopted for statistical analysis.Results The mRNAs of HMGBI, RORyt and IL-17 in RA patients were higher than that in healthy control group (P<0.05), especially in active RA patients [ HMGB 1 (0.424±0.262) pg/ml, RORγt (0.34±0.25) pg/ml,IL-17 (1.42±0.38) pg/ml,P<0.01 ] when compared with patients with stable disease. The concentration of HMGB1, IL-23 and IL-17 in the plasma of RA patients was higher than that of the healthy control group (P< 0.05), and was positively correlated with the expression levels of HMGB1, Th 17-associated factors and the level of CRP, ESR, RF in RA patients' plasma(P<0.05). Conclusion The HMGB1 and Thl7 cells levels are higher in active RA patients than those in patients with stable disease, arid there is significant positive correlation between them. Detection of peripheral HMGB1 and Thl7 cell-specific transcription factors or related cytokines can help to understand the development and progress of rheumatoid arthritis and provide clues for new treatment targets for RA.

Objective: To investigate the clinical significance of monitoring ETV6-RUNX1 fusion gene in children with acute lymphoblastic leukemia (ALL) after allogeneic stem cell transplantation (allo-HSCT) . Methods: Clinical data of 13 children received allo-HSCT in Peking University Institute of Hematology from May 2009 to March 2016 were retrospectively collected. The ETV6-RUNX1 gene was examined by real-time quantitative polymerase chain reaction (RQ-PCR) . The correlation between its expression level and the disease status was analyzed. Results: Of 13 enrolled ALL cases, the ETV6-RUNX1 expression of 7 patients converted to positive after transplant at a median time of 137 days (range, 28-270 days) . The expression level of the first positive sample was 0.034% (range, 0.004%-0.061%) . The duration from ETV6-RUNX1 positive to hematological relapse was 196 days (range, 28-666 days) . Four patients experienced relapse at a median time of 294 days (range, 104-803 days) after allo-HSCT. The ETV6-RUNX1 expression converted to positive prior to MRD. Patients with positive ETV6-RUNX1 gene expression pre-transplantation would be more likely to relapse. Conclusion Monitoring ETV6-RUNX1 by RQ-PCR could be used to evaluate MRD status after allo-HSCT. Patients with positive ETV6-RUNX1 after transplant had a poor prognosis.

Objective:To analyze the safety and efficacy of PD-1 inhibitors versus chemotherapy or ipilimumab in advanced melanoma.Methods:PubMed,CNKI,VIP and Wanfang databases were searched to collect randomised controlled trials of PD-1 inhibi-tors in treatment of advanced melanoma.The search time was from the establishment of the database to May 1,2022.Two reviewers independently screened the literature,extracted data,and assessed risk of bias of included studies.Meta-analysis was performed using RevMan5.4 and STATA16 software.Results:A total of 7 studies were included.Meta-analysis results show that:①Safety:Compared with chemotherapy,PD-1 inhibitor treatment had fewer adverse events,especially in the blood system;compared with ipilimumab alone,PD-1 inhibitor combined with ipilimumab had more adverse events,especially liver function indicators;there was no signifi-cant difference in the incidence of total adverse events between PD-1 inhibitor monotherapy and ipilimumab monotherapy.②Efficacy:The PFS,OS and ORR of PD-1 inhibitor versus chemotherapy or ipilimumab were HR=0.54,95%CI(0.45,0.62),P<0.05,HR= 0.69,95%CI(0.58,0.80),P=0.03 and OR=3.16,95%CI(2.59,3.86),P<0.05,respectively.Conclusion:PD-1 inhibitors have good efficacy in treatment of advanced melanoma,while different combination methods and different control treatments may have different efficacy.Limited by the quantity and quality of included studies,more research evidence is needed to support this.

[Abstract] Objective: To systematically evaluate the efficacy and safety of nivolumab plus ipilimumab versus nivolumab monotherapy in the treatment of malignant tumors, so as to provide evidence-based medical proof for clinical administration. Methods: Databases, such as PubMed, CNKI, VIP, and Wanfang Data, were searched from January 2000 to January 2022 to collect the clinical trial data in terms of nivolumab plus ipilimumab versus nivolumab monotherapy for malignant tumors were published in both domestic and abroad. Two reviewers independently evaluated the quality of included RCTs, and extracted and cross-checked the data. RevMan 5. 4 was used for the Meta-analysis. Results: A total of 7 RCTs studies including 10 articles were included. Compared with the nivolumab monotherapy group, the OS of patients in the combined treatment group was significantly improved (HR=0.86, 95% CI:0. 75-0.99, P=0. 03), and the PFS was significantly prolonged (HR=0.69, 95% CI: 0.55-0.85, P=0.000 6). However, as for safety, treatment-related adverse events (OR=3.18, 95% CI: 1.55-6.55, P=0.002) and adverse events leading to drug discontinuation (OR=7.11, 95% CI: 4.85-10.42, P<0.000 01) in the combination therapy group were significantly higher than those in the monotherapy group. Conclusion: Compared with nivolumab monotherapy, nivolumab plus ipilimumab can significantly improve the OS and PFS of tumor patients, but is also associated with more treatment-related adverse events and adverse events leading to drug discontinuation. Therefore, it is necessary to pay attention to follow-up and regular monitoring to prevent the occurrence of serious adverse reactions.
