The language expression level of doctors directly affects the effectiveness of information transmission and communication. In the past 20 years， a large number of studies have conducted questionnaire surveys related to “doctor-patient communication” among medical staff and patients in the form of scales， but there were few studies on the practical application of doctor-patient communication and case analysis of doctor-patient disputes. Using the Complaint Register Book of a tertiary A hospital as research material， this paper summarized five causes of medical disputes caused by medical remarks， namely， stiff tone and improper body language of the medical staff， unclear communication of treatment plans， unable to answer patients’ questions， different doctors’ statements are contrary each other， and a large gap between disease prediction and disease development. This paper aimed to analyze the handling points of such disputes， with a view to applying them in doctor-patient communication courses for medical students or language skills training for doctors in the future， optimizing doctor-patient communication， and promoting the development of doctor-patient relationships.

Objective To explore the value of prophylactic anticoagulation in the 28-day prognosis of patients with severe COVID-19.Methods The clinical data of COVID-19 patients admitted to Guangdong Provincial People's Hospital from December 2022 to January 2023 were collected,including age,gender,past medical history,routine blood test,liver and renal function,procalcitonin,coagulation function,Padua prediction score,antiviral therapy,hormonotherapy,immunotherapy and anticoagulation therapy.The patients were divided into an anticoagula-tion group and a non-anticoagulation group.The differences in various indicators were compared between the two groups.Cox regression was performed to assess the independent risk factors for 28-day mortality and the anticoagula-tion efficacy between the subgroups.Results Among 158 patients,128 received anticoagulation;There were significant differences between the two groups in case number of hypertension and critical condition,lymphocyte count,prothrombin time,D-dimer,and case number of immunotherapy.COX logistic regression showed that antico-agulation(HR = 2.25,95%CI:1.01～5.01,P = 0.048)was an independent risk factor for all-cause mortality of COVID-19 patients within 28 days.Subgroup analysis showed that anticoagulation therapy led to an increase in the 28-day mortality as level of procalcitonin of≥0.5 pg/mL(HR = 2.72,95%CI:1.05～7.04)or D-dimer of<2 000 ng/mL(HR = 9.16,95%CI:1.63～51.48).Conclusions Prophylactic anticoagulation did not reduce all-cause mortality of COVID-19 within 28 days.

Since the discovery of circulating hepatitis B virus (HBV) RNA in the peripheral blood of patients with chronic hepatitis B in 1996, a growing number of studies have focused on clarifying the biological characteristics and clinical application value of serum HBV RNA. This consensus mainly summarizes the research progress of serum HBV RNA existing profiles, quantitative detection methods, and current clinical applications. In order to better apply this indicator for the clinical management of patients with chronic HBV infection, recommendations on quantitative detection target regions, detection results, and clinical applications are put forward.

Objective:To explore the expression and clinical significance of immunosuppressive receptor T cell immunoglobulin and immunoreceptor tyrosine-based inhibitory motif domain (TIGIT) on the peripheral blood mononuclear cells (PBMC) in silicosis patients with Mycobacterium tuberculosis infection. Methods:August 2018, a total of 78 patients with silicosis (all were quarry workers in Sanmen County, Zhejiang Province) were enrolled and divided into silicosis combined with active pulmonary tuberculosis group (APTB group), silicosis combined with latent tuberculosis infection group (LTBI group), and simple silicosis with non-tuberculosis infection group (non-TB group). Flow cytometry was used to analyze the expressions of TIGIT, programmed death-1 (PD-1) and transcription factor T-bet on PBMC from patients. Mann-Whitney U test and Pearson correlations analysis were used for statistical analysis. Results:Among the 78 patients, eight were in the APTB group, 24 in the LTBI group, and 46 in the non-TB group. The expressions of PD-1 and TIGIT on CD8 + T cells in the APTB group (29.45%(16.78%) and 65.40%(12.12%), respectively) were significantly higher than those in the LTBI group (17.40%(11.17%) and 48.30%(28.75%), respectively; U=23.500 and 43.500, respectively, P=0.000 8 and 0.020 5, respectively) and non-TB group (15.95%(12.46%) and 45.30%(19.75%), respectively; U=64.000 and 69.000, respectively, P=0.002 3 and 0.003 8, respectively), and the differences were all statistically significant. The expression of TIGIT was positively correlated with PD-1 on CD8 + T cells in silicosis patients ( r=0.434 3, P<0.01). The proportion of PD-1 + TIGIT + CD8 + T cells in the APTB group (19.90%(22.67%)) was significantly higher than those in the non-TB group (11.55%(11.29%), U=76.500, P=0.007 1) and LTBI group (11.55%(10.53%), U=41.000, P=0.015 4), while the proportion of PD-1 -TIGIT -CD8 + T cells in the APTB group (30.60%(12.90%)) was significantly lower than non-TB group (48.90%(18.98%), U=58.000, P=0.001 3) and LTBI group (47.20%(24.59%), U=41.000, P=0.015 4). The differences were all statistically significant. The expression of T-bet on the peripheral blood CD8 + T cells in the APTB group (29.45%(16.78%)) was higher than that in the non-TB group (15.95%(12.46%)) and the LTBI group (17.40%(11.17%)), and the differences were both statistically significant ( U=46.500 and 46.000, respectively, P=0.000 3 and 0.028 3, respectively). The expression of T-bet on CD8 + T cells was positively correlated with TIGIT on CD8 + T cells ( r=0.456 7, P<0.01). The expression of T-bet on PD-1 + TIGIT + CD8 + T cells in the APTB group (65.40%(12.12%)) was higher than those in the LTBI group (48.30%(28.75%), U=23.500, P=0.000 8) and non-TB group (45.30%(19.75%), U=65.000, P=0.002 6), and the differences were both statistically significant. Conclusion:The immunosuppressive receptor PD-1 and TIGIT are highly expressed on CD8 + T cells in silicosis patients with active pulmonary tuberculosis, which indicates CD8 + T cells exhaustion in these population, while the highly co-expression of T-bet suggests the exhausted subsets may have reversed potentiality.

OBJECTIVE: To assess the predictors and outcomes of acute kidney injury (AKI) among patients with coronavirus disease 2019 (COVID-19). OBJECTIVE: This retrospective observational study was conducted among patients with a confirmed diagnosis of COVID-19 admitted to Hankou Hospital between January, 5 and March 8, 2020. We evaluated the association of AKI with the demographic and biochemical parameters and clinical outcomes of the patients using univariate regression analysis. OBJECTIVE: Atotal of 287 COVID-19 patients, including 55 with AKI and 232 without AKI, were included in the analysis. Compared with the patients without AKI, the patients with AKI were older, predominantly male, and were more likely to have hypoxia and pre-existing hypertension and cerebrovascular diseases. The patients with AKI also had higher levels of white blood cells, D-dimer, aspartate aminotransferase, total bilirubin, creatine kinase, lactate dehydrogenase, procalcitonin, C-reactive protein, a higher prevalence of hyperkalemia, lower lymphocyte counts, and higher chest computed tomographic scores. The incidence of stage 1 AKI was 14.3% and that of stage 2 or 3 AKI was 4.9%. The patients with AKI had much higher mortality rate than those without AKI. OBJECTIVE AKI is an important complication of COVID-19. An older age, a male gender, multiple pre- existing comorbidities, lymphopenia, increased infection indicators, elevated D-dimer, and impaired heart and liver functions are all potential risk factors ofAKI. COVID- 19 patients with AKI that progresses into stages 2 or 3 AKI have a high mortality rate. Prevention of AKI and monitoring kidney function is critical in the care of COVID-19 patients.

Objectives To evaluate the effectiveness and safety of peramivir trihydrate in patients with influenza.Methods This was a randomized,double-blind,double-dummy,placebo and positive control,multicenter clinical trial,comparing peramivir trihydrate with oseltamivir and placebo.The inclusive criteria were 15-70 years old,onset within 48 h,positive rapid influenza antigen test,and febrile(＞38℃) accompanied with at least two associated symptoms.The severe cases complicated with chronic pulmonary and cardiac diseases,malignancies,organ transplantation,hemodialysis,uncontrolled diabetes,immunocompromised status,pregnancy and coexistence of bacterium infections were excluded.All patients were randomized 2:2:1 to receive peramivir,oseltamivir and placebo respectively.The primary endpoint was the disease duration,the secondary endpoints included time to normal axillary temperature and normal living activities,viral response,and adverse effects.Results Following informed consent,133 patients were included in this study.Four patients were exclude due to missing medical records,not fitting inclusion or exclusion criteria and poor compliance.A total of 129 patients were finally analyzed,including 49 cases,54 cases and 26 cases in peramivir group,oseltamivir group and placebo group.The median disease duration were 96 (76,120)hours,105(90,124) hours,and 124 (104,172)hours in three groups respectively(P＞0.05).The time to normal axillary temperature,normal living activities and viral response were not significantly different in three groups(P＞0.05).Conclusion The value of antiviral therapy in patients with mild influenza needs to be further determined.

Objective: To analyze the survival time of people living with HIV/AIDS and related influencing factors in Sichuan province during 1991-2017. Methods: A retrospective cohort study was conducted to analyze the data of 143 988 HIV/AIDS cases. The data were collected from Chinese HIV/AIDS Comprehensive Information Management System. Life table method was used to calculate the survival proportion of the cases, and Cox proportion hazard regression model was used to identify the factors related with survival time. Results: Among 143 988 HIV/AIDS cases a total of 30 420 cases died of AIDS related diseases (21.1%) and the average survival time was 11.51 years (95%CI: 11.39-11.64). Multivariate Cox regression analysis showed that the influencing factors for the survival of HIV/AIDS cases were gender (male vs. female, HR=1.35, 95%CI: 1.32-1.40), education level (primary school or below vs. junior middle school: HR=1.15, 95%CI: 1.12-1.18), ethnic group (Han vs. other ethnic groups, HR=1.46, 95%CI: 1.41-1.52), occupation (farmer vs. other occupations: HR=1.26, 95%CI: 1.22-1.29), age (≥55 years old vs. 15-24 years old: HR=3.18, 95%CI: 3.02- 3.36), disease phase (AIDS vs. HIV infection: HR=1.44, 95%CI: 1.39-1.48), antiretroviral therapy (ART) (receiving ART vs. receiving no ART: HR=0.20, 95%CI: 0.19-0.20), and CD₄⁺T cell counts at diagnosis (>500 cells/μl vs.<200 cells/μl: HR=0.42, 95%CI: 0.40-0.45). Conclusions The average survival time of HIV/AIDS cases was 11.51 years in Sichuan during 1991- 2017. The risk factors for the survival of the cases were male, education level of primary school or below, Han ethnic group, farmer, old age at diagnosis, disease phase, The protective factors for the survival of HIV/AIDS cases were receiving ART and higher CD₄⁺ T cell counts at diagnosis.

Objective? To explore the effects of acupoints moxibustion on urination among patients with selective mucosectomy. Methods? From February 2015 to February 2018, we selected 100 hemorrhoids patients in anorectal surgery at Zhejiang Provincial Hospital. All of the patients were randomly divided into experimental group and control group with the randomization scale produced by SPSS 17.0, 50 cases in each group. Control group implemented routine nursing. On the basis of routine nursing, experimental group carried out acupoints moxibustion. We observed the first urination time, volume of the first urination and maximal urinary flow rate of patients between two groups. Results? There was no statistical difference in the volume of the first urination of patients between two groups (P＞ 0.05). There were statistical differences in the first urination time, maximal urinary flow rate of the first urination and the rate of catheterization (P＜ 0.05). Conclusions? Acupoints moxibustion can reduce the first urination time, improve maximal urinary flow rate of the first urination, and decrease the rate of catheterization among patients undergoing selective mucosectomy to improve urination which is worth to be widely generalized in clinic.

[Abstract] Objective: To investigate the effect of sphingosine kinase 1 (SphK1) knockdown on the proliferation and migration of colon cancer RKO cells induced by mesenchymal stem cells (MSCs). Methods: RKO cells were treated with MSCs conditioned medium (MSC-CM) or control medium (Control-CM), respectively. Cell proliferation was detected by CCK-8 assay. Cell migration ability was tested by Transwell chamber assay. The proteins expression of Ki-67, MMP-2/9, CD44 and CD133 was detected by Western blotting. Then, the expression of SphK1 in RKO cells was suppressed by targeted gene lentivirus shRNA vector transfection. The effects of SphK1 knockdown on the proliferation, migration and protein expressions of Ki-67, MMP-2/9, CD44 and CD133 of RKO cells induced by MSC-CM were observed. Results: The RKO cells proliferation was promoted by MSC-CM in a time-dependent manner; moreover (P<0.05), the migration ability of cells was significantly enhanced after being treated with MSC-CM(P<0.01). In addition, MSC-CM significantly increased the protein expressions of Ki-67, MMP-2/9, CD44 and CD133(all P<0.05 or P<0.01). Lentiviral ShRNA vector transfection could significantly inhibit the expression of SphK1. Down-regulation of SphK1 significantly inhibited the proliferation, migration and protein expressions of Ki-67, MMP-2/9, CD44 and CD133 of RKO cells induced by MSC-CM(all P<0.05 or P<0.01). Conclusion: MSC-CM promotes the proliferation and migration of colon cancer RKO cells. Down-regulation of SphK1 reverses the cell proliferation and migration induced by MSC-CM via inhibiting the expression of MMP-2/9, CD44 and CD133.
