Objective: To investigate the characteristics of attentional bias in emotional faces of policemen with different trait anxiety levels. Methods: By using the State-Trait Anxiety Inventory (STAI), 44 policemen (23 males and 21 females) were included in the higher trait anxiety level group and 44 policemen (25 males and 19 females) were included in the lower trait anxiety level group. The 2 anxiety style ((higher trait anxiety level, lower trait anxiety level) × 2 emotional type (positive, negative) × 2 clue type (identical side, opposite side) hybrid design was used to investigate the attentional bias of the response time differences between the two groups of policemen on keystroke responses of different emotional types and different types of clues by using a dot probe. Results: The positive emotional face reaction of the higher trait anxiety level group was less than that of the negative emotional face reaction[ (638. 0 ± 12. 4) ms vs. (651. 7 ± 13. 1) ms, P ＜ 0. 01], while the lower trait anxiety level police had no statistical significance on the reaction of positive emotional face and negative emotional face (P＞ 0. 05). The clue types in the higher trait anxiety level group were identical side less than opposite side response time [ (640. 3 ± 12. 6) ms vs. (649. 5 ± 13. 0) ms, P ＜ 0. 05], and there was no statistical significance in the lower trait anxiety level group about identical side and opposite side response time (P＞ 0. 05). The clue type in identical side, there was no significant difference in the response of two groups to positive emotional faces and negative emotional faces (P＞ 0. 05); while the clue type in opposite side, the response of higher trait anxiety level group to negative emotional faces was higher than that of positive emotional faces [ (663. 1 ± 9. 8) ms vs. (651. 4 ± 8. 9) ms, P ＜ 0. 05]. Conclusion: It suggests that the policemen with higher level of trait anxiety have selective attentional bias to negative emotional faces, which induced by impaired attentional disengagement.

Objective:To explore the surgical experience of high speed rotary excision combined with multi-technology in the treatment of adult nape-fat-pad.Methods:A total of 83 patients with nape-fat-pad in our department from March 2016 to September 2019 were selected for the study. In this marked area, 0. 2 percent lidocaine with 1∶10 000 epinephrine was used for local tumescent anesthesia, then a skin incision of about 0.5 cm was made directly under the fat pad and/or about 2 cm from it. First, use a fork knife to separate the fat pad at multiple planes and angles, then cut off with a rotary excision and sucked out thoroughly. Second, use a thin liposuction tube to pump the transition area between the nape-fat-pad and normal fat until the transition is natural and smooth. Finally, fix the skin in the separation area with oil nail, apply pressure with "8-form" bandage and sleep on the rice pillow for 1 week after surgery. The appearance of the neck, postoperative complications and patient satisfaction were followed up 3-6 months after the operation.Resuts:83 patients had varying degrees of pain and swelling for 1-2 months after operation, 76 cases(91.57%) of the patients had complete disappearance of swelling in about 1 month, 12 cases(14.46%)had cyanosis and ecchymosis, which improved in about 3 weeks, 5 cases(6.02%) had a sense of subcutaneous cord or induration, and recovered completely in 2-3 months. Subcutaneous effusion was found in 2 patients(2.41%) in the early stage of operation and absorbed about 1 week.4 cases (4.82%) had a slight "sense of step" in the operative and normal fat transition area about 1 month after operation. 3 cases (3.61%)had poor wound healing, and the other 80 cases (96.39%)were grade A healing. There was no abnormal skin sensation in the operation area in all the 83 cases.No serious complications such as skin necrosis infection and important vascular injury occurred in all the patients 3 to 6 months after the operation. In the patient satisfaction survey, 70 patients were satisfied, 9 were satisfied, 4 were average, the satisfaction rate of the patients was 95.18%.Conclusions:The high speed rotary excision combined with multi-technology in the treatment of nape-fat-pad has short operation time, good curative effect, few complications and high patient satisfaction.

Background and Objective: Ewing's sarcoma family of tumor (ESFT)is aggressive.The optimal therapy modality for ESFT is still to be found.This study was to explore the clinicaI characteristjcs and therapy for ESFT.Methods:Ninety-two cases of ESFT were collected from January 1995 to April 2008 in Sun Yat-sen University Cancer Center and analyzed retrospectively.Result:Of 92 cases,23 were Ewing's sarcoma of bone,21 extraosseous Ewing's sarcoma,43 peripheral primitive neuroectodermal tumor,and 5 Askin tumor.Median follow-up time was 31.5 months(range,10-137months).Thirty-eight patients received multidisciplinary therapy and 19 single model therapy in non-metastasis group.Three-year overall survival (OS) and event-free survival (EFS) were significantly different between non-metastatic multidisciplinary therapy group and non-metastatic single model group(63%vs.20%.46%vs.18%,respectively,P<0.001).The patients who received surgery plus chemotherapy and plus radiation or not had longer survival than those treated with chemotherapy plus radiation in non-metastatic multidisciplinary therapy group(χ~2=7.591, 9.212;P=0.006,0.002).CAV/IE alternative regimen was superior to other regimens in event-free survival,but not in overall survival(χ~2=6.950,3.530;P=0.008,0.06).Cox regression analysis suggested therapy model and response to treatment were independent prognostic factors for ESFT.Conclusions:Our studying showed multidisciplinary therapy could significantly improve non-metastatic ESFT patients'survival.Chemotherapy plus surgery and plus radiation or not were superior to chemotherapy plus radiation in local control for the non-metastatic ESFT,Therapy model and response were independent prognostic factors.

Systemic chemotherapy is the basic palliative treatment for metastatic nasopharyngeal carcinoma (NPC); however, it is not known whether locoregional radiotherapy targeting the primary tumor and regional lymph nodes affects the survival of patients with metastatic NPC. Therefore, we aimed to retrospectively evaluate the benefits of locoregional radiotherapy. A total of 408 patients with metastatic NPC were included in this study. The mortality risks of the patients undergoing supportive treatment and those undergoing chemotherapy were compared with that of patients undergoing locoregional radiotherapy delivered alone or in combination with chemotherapy. Univariate and multivariate analyses were conducted. The contributions of independent factors were assessed after adjustment for covariates with significant prognostic associations (P < 0.05). Both locoregional radiotherapy and systemic chemotherapy were identified as significant independent prognostic factors of overall survival (OS). The mortality risk was similar in the group undergoing locoregional radiotherapy alone and the group undergoing systemic chemotherapy alone [multi-adjusted hazard ratio (HR) = 0.9, P = 0.529]; this risk was 60% lower than that of the group undergoing supportive treatment (HR = 0.4, P = 0.004) and 130% higher than that of the group undergoing both systemic chemotherapy and locoregional radiotherapy (HR = 2.3, P < 0.001). In conclusion, locoregional radiotherapy, particularly when combined with systemic chemotherapy, is associated with improved survival of patients with metastatic NPC.

Objective To determine the adherence to and its determinants of methadone maintenance treatment (MMT) among heroin addicts in Dehong prefecture in Yunnan province from 2005 to 2009. Methods A dynamic cohort analysis was conducted with the time of treatment initiation as the time of cohort entry, to calculate the proportion of adhering to the treatment at different time points after initiation of the treatment, and to study the determinants of adherence.Results A total of 3758 had been treated. Among them, 95.8% were males, 75.8% aged between 20-39 years, 90.4% were peasants or unemployed, 57.0% were ethnic minorities, 35.0% were single and 55.5% were married with spouses, 43.9% were illiterate or educated at most primary school. The age of first using drugs averaged at 23.93 years. About 96.3% of the study subjects had used heroin and 21.7% were HIV-infected. The minimum time under MMT was less than 1 month and the maximum 61 months. The median methadone dose at first delivery was 25 ml, with the minimum 1 ml and the maximum 330 ml. By the end of the study or observation period, a total of 1798 patients had withdrawn from treatment and 1960 were still under treatment. The proportions of adherence to or still being under the treatment after 1,3,6,9, 12,24, 36,48 and 60 months treatment were 0.919,0.847,0.756, 0.690, 0.637, 0.519, 0.417, 0.360 and 0.321, respectively. Multiple regression analysis using Cox proportional hazard model indicated that withdraw from the methadone maintenance treatment was significantly associated with location of the treatment clinics, year of treatment initiation, marital status, HIV infection status, methadone dose of first delivery and the result of last urine test for heroin use. Conclusion MMT attendants in Dehong prefecture had a relatively high withdraw rate and low adherence rate. More efforts are needed to provide tailored counseling and education to MMT attendants, to provide family and community support, appropriate methadone dose at first delivery, and to better coordinate with local police department.

Introduction:Patients with metastatic nasopharyngeal carcinoma (NPC) have variable survival outcomes. We have previously shown that an elevated peripheral blood lymphocyte-to-monocyte ratio (LMR) is associated with an increased metastatic risk in patients with primary NPC. The present study aimed to investigate the prognostic value of pretreatment LMR in a large cohort of metastatic NPC patients. Methods:Clinical data of 672 patients with metastatic NPC diagnosed between January 2003 and December 2009 were analyzed. The peripheral lymphocyte and monocyte counts were retrieved, and LMR was calculated. Receiver operating characteristic (ROC) curve analysis and univariate and multivariate COX proportional hazards analyses were performed to evaluate the association of LMR with overall survival (OS). Results:Univariate analysis revealed that an elevated absolute lymphocyte count (≥1.390 × 109/L) and LMR (≥2.475) as well as a decreased monocyte count (<0.665 × 109/L) were significantly associated with prolonged OS. Multivariate Cox proportional hazard analysis showed that LMR (hazard ratio [HR]=0.50, 95%confidence interval [CI]=0.41–0.60, P<0.001), absolute lymphocyte count (HR=0.77, 95%CI=0.64–0.93, P=0.007), and monocyte count (HR=1.98, 95%CI=1.63–2.41, P<0.001) were independent prognostic factors. By stratification analyses, only LMR remained a significant predictor of prognosis. Conclusion:We identified pretreatment LMR as an independent prognostic factor for patients with metastatic NPC. Independent validation of our findings is needed.

OBJECTIVE To observe the changes of cardiac function,local inflammation level and macrophage M2 polarization in mice with acute myocardial infarction(AMI after electroacupuncture preconditioning at the Neiguan point,and to explore the possible mechanisms from the perspective of regulating the DNA-PK/Rictor/Myc signaling pathway.METHODS Male C57BL/6J mice were randomly divided into sham group,model group and electroacupuncture group,with 10 mice in each group.The electroacupuncture group received bilateral electroacupuncture interventions at the Neiguan points,sparse-dense wave,2/15 Hz,1 mA,20 min/time,once a day for 3 consecutive days,and AMI models were performed 0.5 h after the electroacupuncture interventions.The myocardial ischemia model was prepared by ligating the left anterior descending branch.Echocardiography was used to detect cardiac ejection frac-tion(EF and fractional shortening(FS to evaluate cardiac function;HE and TUNEL staining were used to observe the pathological morphology of myocardium and apoptosis of cardiomyocytes,and immunohistochemistry and ELISA were used to detect IL-1β,TNF-α and NLRP3 in infarcted myocardium and peripheral blood to evaluate the level of inflammation;flow cytometry was used to detect cardiac macrophage polarization status,and Western blot method to detect the protein expression levels of DNA-PK,p-DNA-PK,Rictor and Myc in infarcted myocardium.RESULTS Compared with the sham group,the model group showed significantly lower EF and FS(P<0.000 1,significant inflammatory cell infiltration,significantly higher cardiomyocyte apoptotic index(P<0.001,up-regulated expression of IL-1β,NLRP3 and TNF-α in the myocardium and serum(P<0.01,P<0.001,a significant increase in the percentage of macrophages(P<0.001,a decrease in the percentage of cardiac M2-type macrophages(P<0.000 1,and a significant decrease in the expression levels of p-DNA-PK,Rictor and Myc proteins in myocardium(P<0.05,P<0.000 1.Compared with the model group,EF and FS were significantly higher in the electroacupuncture group(P<0.000 1,inflammatory cell infiltration was re-duced,cardiomyocyte apoptotic index was decreased(P<0.01,and the expression of IL-1β,NLRP3 and TNF-α was down-regula-ted in myocardium and serum(P<0.05,P<0.01,P<0.001;the macrophage percentage was decreased(P<0.05,cardiac M2-type macrophage percentage was increased(P<0.01,and p-DNA-PK,Rictor and Myc protein expression was enhanced in myocardium(P<0.05,P<0.01,P<0.000 1.CONCLUSION Electroacupuncture preconditioning may promote macrophage M2 polarization,attenuate local inflammation,and reduce cardiomyocyte apoptosis by modulating the DNA-PK/Rictor/Myc signaling pathway,thus im-proving cardiac function and achieving myocardial protective effects.

INTRODUCTIONPatients with metastatic nasopharyngeal carcinoma (NPC) have variable survival outcomes. We have previously shown that an elevated peripheral blood lymphocyte-to-monocyte ratio (LMR) is associated with an increased metastatic risk in patients with primary NPC. The present study aimed to investigate the prognostic value of pretreatment LMR in a large cohort of metastatic NPC patients.

METHODSClinical data of 672 patients with metastatic NPC diagnosed between January 2003 and December 2009 were analyzed. The peripheral lymphocyte and monocyte counts were retrieved, and LMR was calculated. Receiver operating characteristic (ROC) curve analysis and univariate and multivariate COX proportional hazards analyses were performed to evaluate the association of LMR with overall survival (OS).

RESULTSUnivariate analysis revealed that an elevated absolute lymphocyte count (≥1.390×10(9)/L) and LMR (≥2.475) as well as a decreased monocyte count (<0.665×10(9)/L) were significantly associated with prolonged OS. Multivariate Cox proportional hazard analysis showed that LMR (hazard ratio [HR]=0.50, 95% confidence interval [CI]=0.41-0.60, P<0.001), absolute lymphocyte count (HR=0.77, 95% CI=0.64-0.93, P=0.007), and monocyte count (HR=1.98, 95% CI=1.63-2.41, P<0.001) were independent prognostic factors. By stratification analyses, only LMR remained a significant predictor of prognosis.

CONCLUSIONWe identified pretreatment LMR as an independent prognostic factor for patients with metastatic NPC. Independent validation of our findings is needed.

ObjectiveTo investigate the efficacy of Bushen Shengxue prescription and Yiqi Yangxue prescription in the treatment of chronic aplastic anemia and the effect on T cell subsets and the expression of T-box expressed in T cells （T-bet） and GATA binding protein 3 （GATA3）. MethodA total of 585 patients with chronic aplastic anemia who were treated in 19 hospitals in China from May 2018 to June 2021 were enrolled. With the prospective， double-blind and randomized control methods， the patients were randomized into three groups： kidney deficiency group， Qi and blood deficiency group， and control group. The three groups were respectively treated with Bushen Shengxue prescription granule， Yiqi Yangxue prescription granule， and Placebo （half the dose of Bushen Shengxue formula granules）. In addition， all of them were given oral cyclosporin and androgen. The treatment lasted 6 months， with 3 months as a course. The blood routine indexes， T cell subsets， and fusion genes T-bet and GATA3 before and after treatment were analyzed， and the safety indexes were monitored. ResultDuring the observation， a total of 75 cases dropped out and 18 were rejected. Finally， 161 cases in the kidney deficiency group， 164 in the Qi and blood deficiency group， and 167 in the control group were included. After 6 months of treatment， the total effective rate was 98.8% （159/161） in the kidney deficiency group， which was higher than the 79.9% （131/164） in the Qi and blood deficiency group （χ²=30.135， P<0.01） and the 61.7% （103/167） in the control group （χ²=70.126， P<0.01）. The total effective rate was higher in the Qi and blood deficiency group than in the control group （χ²=13.232， P<0.01）. After treatment， the hemoglobin （HGB） content increased significantly in three groups （P<0.05） as compared with that before treatment， particularly the kidney deficiency group （P<0.01）. After treatment， the white blood cell （WBC） count and platelet （PLT） count in the kidney deficiency group and the control group increased compared with those in the Qi and blood deficiency group （P<0.01）. There was no specific difference in neutrophils （ANC） after treatment among the three groups. At the same time point， the level of T helper type 1 （Th1） cells， Th1/Th2 ratio （P<0.05）， level of CD4⁺， and CD4⁺/CD8⁺ ratio （P<0.05） were significantly low in the kidney deficiency group among three groups. There was no significant difference in CD19^-， HLA/DR⁺， and CD25⁺ between the kidney deficiency group and the other two groups， but the T-bet of the kidney deficiency group and the control group was lower than that of the Qi and blood deficiency group （P<0.05）. ConclusionBushen Shengxue prescription exerts therapeutic effect on the aplastic anemia by improving the immunoregulatory mechanism， inhibiting the activity of immune system， modulating T cell subsets， suppressing Th1 and CD4⁺， and promoting bone marrow hematopoiesis. Moreover， it is safe with little side effects， which is worthy of further promotion.
