RESUMEN
Objective:To investigate whether tetrandrine could be used as an agonist of cGAMP to enhance the activation of cGAS-STING signaling pathway and analyze the antiviral function of tetrandrine.Methods:THP1-Lucia-ISRE and RAW-Lucia-ISRE cells were incubated with different doses of tetrandrine in combination with cGAMP, respectively. IRF3 reporter activity was analyzed by luciferase reporter assay. Western blot was used to detect the activation of cGAS-STING signaling pathway. The expression of IFN-β, CXCL10 and CCL5 at mRNA level was quantified by real-time quantitative PCR. The expression of IFN-β at protein level was assessed by ELISA. HeLa cells stably expressing STING-GFP gene (HeLa-STNG-GFP cells) were constructed and stimulated with tetrandrine and cGAMP, then puncta-like structures were imaged by ZEISS LSM780. THP1-Lucia-ISRE cells were infected with herpes simplex virus type 1 (HSV-1) in the presence or absence of tetrandrine or cGAMP. The antiviral function of tetrandrine was analyzed by Western blot and fluorescence intensity assay.Results:Tetrandrine enhanced cGAMP-mediated IRF3 responses and activated cGAS-STING signaling pathway in combination with cGAMP. Tetrandrine combined with cGAMP triggered STING translocation and the formation of puncta-like structures in HeLa-STNG-GFP cells. The titer of HSV-1, the expression of HSV-glycoprotein D/UL30 and the fluorescence intensity of HSV-GFP were all decline after treating HSV-1-infected THP1-Lucia-ISRE cells with tetrandrine and cGAMP.Conclusions:Tetrandrine combined with cGAMP activates cGAS-STING signaling pathway, thus enhancing the host antiviral response.

Objective To predict the potential suitable habitat of Haemaphysalis concinna in Heilongjiang Province under different climatic scenarios. Methods The geographic locations of ticks in Heilongjiang Province from 1980 to 2022 were captured from literature review and field ticks monitoring data from Harbin Center for Disease Control and Prevention in Heilongjiang Province, and the tick distribution sites with spatial correlations were removed using the software ArcGIS 10.2. The environment data under historical climatic scenarios from 1970 to 2000 and the climatic shared socioeconomic pathways (SSP) 126 scenario model from 2021 to 2040 and from 2041 to 2060 were downloaded from the WorldClim website, and the elevation (1 km, 2010), population (1 km grid population dataset of China, 2010) and annual vegetation index (1 km, 2010) data were downloaded from the Resource and Environmental Science and Data Center, Institute of Geographical Sciences and Natural Resources, Chinese Academy of Sciences. The contribution of environmental factors to H. concinna distribution was evaluated and environmental variables were screened using the software MaxEnt 3.4.1 and R package 4.1.0, and the areas of suitable habitats of H. concinna and changes in center of gravity were analyzed using the maximum entropy model in Heilongjiang Province under different climatic scenarios. In addition, the accuracy of the maximum entropy model for prediction of H. concinna distribution was assessed using the area under curve (AUC) of the receiver operating characteristic curve. Results A total of 79 H. concinna distribution sites and 24 environmental variables were collected, and 70 H. concinna distribution sites and 9 environmental factors that contributed to distribution of the potential suitable habitats of H. concinna in Heilongjiang Province were screened. The three most significant contributing factors included precipitation seasonality, annual precipitation, and mean temperature of the driest quarter, with cumulative contributions of 60.7%. The total area of suitable habitats of H. concinna was 29.05 × 104 km2 in Heilongjiang Province under historical climatic scenarios, with the center of gravity of suitable habitats located at (47.31° N, 129.16° E), while the total area of suitable habitats of H. concinna reduced by 0.97 × 104 km2 in Heilongjiang Province under the climatic SSP126 scenario from 2041 to 2060, with the center of gravity shifting to (47.70° N, 129.28° E). Conclusions The distribution of suitable habitats of H. concinna strongly correlates with temperature and humidity in Heilongjiang Province. The total area of potential suitable habitats of H. concinna may appear a tendency towards a decline with climatic changes in Heilongjiang Province, and high-, medium- and low-suitable habitats may shift.
RESUMEN
Objective:Clavien-Dindo grading system was used to explore the occurrence and related risk factors of early severe complications after radical resection of gastric cancer, and the effect of severe complications on long-term prognosis was analyzed.Methods:The clinical data of 525 patients who underwent radical resection of gastric cancer, including 387 male and 138 female with average age(62.5±10.7)years old (range from 16 to 89 years), were analyzed retrospectively in Department of Surgical Oncology of Anqing Municipal Hospital from October 2010 to July 2015. The occurrence of postoperative severe complications was analyzed according the Clavien-Dindo grade system.The relationship between 18 variables and severe complications was analyzed by univariate and multivariate analysis in order to explore the risk factors of severe postoperative complications, and the relationship between severe complications and long-term prognosis was analyzed by COX survival model. The software of SPSS 17.0 was used to conduct statistic analysis.Results:Five hundred and twenty-five patients with radical gastrectomy, 114 cases had early postoperative complications, including 20 cases of severe complications, 4 cases were performed second surgery under general anesthesia. The results of univariate analysis showed gender( χ2=4.86, P=0.027), the amount of bleeding( χ2=11.11, P=0.001), opertive time( χ2=4.77, P=0.029), the mode of operation( χ2=9.20, P=0.002) and pTNM stage( χ2=4.86, P=0.027) had significant statistical difference. Multivariate analysis showed that the amount of bleeding ( OR=13.05, P=0.013) and the mode of operation ( OR=7.97, P=0.047) were independent risk factors for early and severe complications after radical resection of gastric cancer. The 5-year survival rates of severe complication and non-severe complication were 35.0% and 61.8% respectively, and the difference was statistically significant ( P=0.004). Severe postoperative complications ( HR=1.595, P=0.107) were not independent risk factors affecting the 5-year survival rate. Conclusions:Early severe complications after radical resection of gastric cancer are closely related to intraoperative blood loss and total gastrectomy. Although the 5-year survival rate in severe complication group is significantly lower than that in non-severe complication group, severe complication is not an independent risk factor for long-term survival.

RESUMEN
Objective:To investigate the relationship between clinicopathological features and lymph node metastasis(LNM)of early gastric cancer(EGC), so as to provide and theoretical guidance for the normative treatment of EGC.Methods:A retrospective analysis was performed on 128 patients with EGC who received surgical treatment from January 2016 to December 2019 in Anhui Medical University Affiliated Anqing hospital.Results:The total LNM ratio of EGC was 10.1% (13/128). Univariate analysis showed that the LNM ratio was 18.0% in patients with the largest diameter of >2 cm, higher than 5.1% in patients with the largest diameter of ≤2 cm. The LNM ratio of submucosal carcinoma (T 1b) was 21.6%, higher than 2.6% of intramucosal carcinoma (T 1a). The LNM ratio of patients with vascular invasion was 71.4%, higher than 6.7% of patients without vascular invasion. The LNM ratio was 13.1% in the total dissected lymph node group ≥15, higher than 0 in the total dissected lymph node group <15. The difference between the these groups was statistically significant( χ2=5.532, 12.101, 23.778, 4.239, P<0.05). There was no significant difference in the correlation between age, gender, tumor site, general type, degree of differentiation, and the LNM of EGC ( P>0.05). Multivariate analysis showed that submucosal carcinoma(RR=10.688, 95% CI: 1.714-66.651, P=0.011) and vascular infiltration(RR=27.209, 95% CI: 3.749-197.450, P=0.001) were the independent risk factor for the LNM of EGC. Conclusions:Patients of EGC with tumor infiltration to submucosa(T 1b), maximum diameter of lesion >2 cm, and vascular infiltration have a higher risk of LNM. Standardized D1+ or D2 lymph node dissection (≥15) should be performed for EGC patients.

OBJECTIVE:To investigate therapeutic efficacy,safety and economics of budesonide for infant bronchiolitis based on salbutamot. METHODS:In prospective study,160 inpatient children with bronchiolitis during Oct. 2014-Apr. 2016 were divid-ed into observation group and control group according to admission order,with 80 cases in each group. Both groups received conventional treatments. Control group was given Salbutamol solution for inhalation 0.25 mL added into 0.9% Sodium chloride injection 3 mL,q8 h. Observation group was given Budesonide suspension for inhalation 2 mL added into 0.9% Sodium chlo-ride injection 1 mL+Salbutamol solution for inhalation 0.25 mL,q8 h. Both groups received oxygen driven inhalation,and treat-ed for 5-7 d. Clinical symptom disappearance time,hospitalization time and clinical efficacy were compared between 2 groups as well as therapy drug cost(aerosol inhalation,other therapy drugs). The occurrence of ADR was recorded. RESULTS:There was no statistical significance in cough disappearance time,wheezing disappearance time,lung rale disappearance time,tri-re-traction sign disappearance time and hospitalization time between 2 groups(P>0.05). There was no statistical significance in to-tal response rate between observation group (95.00%) and control group (92.50%)(P>0.05). The cost of inhalation drugs in observation group [(355.77±10.98)yuan] was significantly higher than control group [(26.83±2.86)yuan],with statistical signif-icance (P0.05). There was no significant ADR between 2 groups during treatment. CONCLUSIONS:For infant bronchiolitis,aerosol inhalation of budesonide based on salbutamol sulfate can not significantly shorten disease,shorten hospitalization time and improve clinical ef-ficacy,but increase therapy cost.
RESUMEN
OBJECTIVE: To explore the current situation of work stress,mental resilience and mental health in the local policemen,and to explore the association among these three variables. METHODS: A total of 260 local policemen in 3 districts of a city in Hebei Province were selected as the study subjects using cluster sampling method. The Chinese version of Perceived Stress Scale,Connor-Davidson Resilience Scale and General Health Questionnaire were used to evaluate their work stress,mental resilience and mental health. RESULTS: There was a negative correlation between work stress and mental resilience( P < 0. 01). Positive correlation was found between work stress and mental health( P < 0. 01). The mental resilience was negatively correlated with mental health( P < 0. 01). The mental resilience could negatively predict mental health( β =-0. 31,P < 0. 01). Work stress could positively predict mental health( β = 0. 56,P < 0. 01). Work stress had a negative prediction on mental resilience( β =-0. 47,P < 0. 01). Mental resilience played a partial mediating role between work stress and mental health( β = 0. 41,P < 0. 01). The mediating effect accounted for 26. 0% of the total effect. CONCLUSION: Mental resilience plays a partial mediating role in influencing work stress on mental health. Reducing work stress and increasing resilience play an important protective role in mental health of local policemen.

RESUMEN
Objective To analyze the genetic characteristics of chromosomes and related fusion genes in acute myeloid leukemia (AML) (non-M3), and to evaluate the prognosis of patients with chemotherapy of DA regimen with different doses of daunorubicin. Methods Fifty-six patients with newly diagnosed non-M3 AML from January 2013 to January 2015 were collected. Adopted short-term culture method was used to treat bone marrow, R-binding chromosome karyotyping was used to detect cytogenetic. Thirty-one types of fusion gene were identified by PCR and 10 % agarose gel electrophoresis. All patients treated by DA regimen were divided into group A, group B and group C according to different dosage of daunorubicin. Then, complete remission (CR) rate and survival time in the 3 groups were observed. The effect of cytogenetic and molecular biology abnormality on the chemotherapy, CR rate and overall survival (OS) of the 3 groups were analyzed by the chi-square test. Results Among the 56 patients, 18 cases (32.1%) had abnormal chromosome karyotype, 6 cases (10.7 %) had abnormal number of chromosome, 16 cases (28.6 %) had abnormal structure of chromosome, and 4 cases (7.1 %) had both abnormal number and structure of chromosome. Meanwhile, the most common abnormal structure was t(8;21), and the most common abnormal quantity were+8, -Y. Detective rate of genetic abnormality was raised to 62.00 % through fusion gene and chromosome karyotype analysis. The total CR rate of DA-induced chemotherapeutic regimen was 73.2 %, and the two-year OS rate was 42.9%. The remission rate of chemotherapy in the middle-risk group was significantly lower than that in the low-risk group (χ 2 = 8.976, P = 0.002), but there was no significant difference between the low-dose chemotherapy group and the standard dose chemotherapy group (P>0.05). The standard dose group showed a significant advantage in the OS rate (χ2= 8.045, P= 0.005). Conclusions Adult acute leukemia has its unique cytogenetic characteristics, which can assist in guiding clinical diagnosis, classification and prognosis. The prognosis of middle-risk patients is significantly lower than the low-risk group. Low-risk patients could benefit from a reduced dose of DA regimen, but the standard dose DA regimen has a significant advantage in long-term survival.

RESUMEN
<p><b>BACKGROUND</b>There are limited eligible clinical markers at present to monitor the progress of chronic myeloid leukemia (CML). Heme oxygenase-1 (HO-1), as one of the most important oxidation-regulating enzymes in vivo, suggests the onset and progression of cancer when highly expressed. Furthermore, HO-1 level is related with the occurrence and development of hematological diseases. But the relationship between HO-1 expression and progression/relapse of CML has seldom been studied hitherto. This study aimed to investigate the relationship between them to find out a new molecular marker for prediction.</p><p><b>METHODS</b>A total of 60 peripheral blood and bone marrow (BM) samples from 25 CML patients in different phases were collected respectively to detect the expressions of HO-1 and bcr/abl using real-time PCR. Routine blood test was performed to detect the changes of leukocyte and platelet counts. The proportion of primitive cells in BM was detected by flow cytometry. The relationship between high HO-1 expression and CML progression and relapse was explored by the analysis of variance by Wilcoxon test and linear regression analysis. The diagnostic accuracy and cutoff values were determined by receiver operating characteristic curve.</p><p><b>RESULTS</b>Relative expression of HO-1 mRNA in CML patients peripheral blood was significantly higher than that of donors (P < 0.0001), which were 0.57±3.78 and (1.417±1.125)×10(-6), respectively. HO-1 expression level in CML patients was 0.061 5±0.062 4, which decreased to 0.009 4±0.006 7 upon CMoR, and remained remarkably higher 0.016 3±0.017 5 than that of normal donors (1.417±1.125)×10(-6), P < 0.001. When relapse occurred, HO-1 expression significantly increased from 0.020 6±0.021 0 to 3.852±10.285 in CMoR stage and undergoing relapse. According to progression of CML, HO-1 expression level in CML patients increased from CP (0.009 5±0.017 6) to AP (0.028 0±0.055 7) and then to BP (0.276 7 ± 0.447 0). And there was a linear correlation between HO-1 expression and proportion of primitive CML cells. The diagnostic accuracies and cutoff values of HO-1 expression for CML-CP, CML-AP, and CML-BP were 1.0, 0.748, and 0.965, respectively, as well as 0.000 070, 0.001 917, and 0.020 696, respectively.</p><p><b>CONCLUSION</b>HO-1 may be a potential molecular indicator for the progression and relapse of CML.</p>
