Objective To study the characteristics of peripheral blood lymphocyte subsets in patients with lung cancer,gastric cancer and breast cancer.Methods Five hundred and eight patients with cancer from the First Affiliated Hospital of Tianjin University of Traditional Chinese Medicine (256 cases with lung cancer,152 cases with gastric cancer,100 cases with breast cancer),and 50 healthy volunteers were collected.Two ml peripheral blood were obtained from these cases.The distribution of lymphocyte subsets in peripheral blood was measured by flow cytometry in these cases.The data were analyzed using SPSS 16.0 software.Results The number of lymphocytes of cancer patients was decreased,the healthy volunteers was 5125,breast cancer patient was 3642,gastric cancer patient was 3178,lung cancer patient was 2895.The case of outliers of lymphocyte subsets classified based on the three kinds of cancer was 218 (85.2％,lung cancer),133 (87.5％,gastric cancer),88 (88.0％,breast cancer).The case of outliers of T-lymphocyte subsets classified based on the three kinds of cancer was 83 (32.4％,lung cancer),32 (32.0％,breast cancer),44 (28.9％,gastric cancer).The case of outliers of CD4 +/CD8 + classified based on the three kinds of cancer was 185 (72.3％,lung cancer),108 (71.1％,gastric cancer),84 (84.0％,breast cancer).The case of outliers of natural killer-lymphocyte subsets classified based on the three kinds of cancer was 32 (12.5％,lung cancer),22 (14.5％,gastric cancer),16 (16.0％,breast cancer).The case of outliers of B-lymphocyte subsets classified based on the three kinds of cancer was 38 (14.8％,lung cancer),52 (34.2％,gastric cancer),12 (12.0％,breast cancer).Compared to healthy subjects,the CD19+％ of patients with lung cancer was decreased (12.8 ± 5.0 vs.11.5 ± 5.7,t =3.006,P =0.003);the CD4 + ％ of patients with gastric cancer was decreased (39.2 ±7.7 vs.35.3 ± 7.6,t =2.315,P =0.023);the CD19 + ％ of patients with gastric cancer was decreased (12.8 ± 5.0 vs.8.9 ± 4.2,t =3.302,P =0.010);the CD8 + ％ of patients with breast cancer was increased (24.0 ± 8.1 vs.29.1 ± 13.0,t =2.019,P =0.047).Conclusion The number of lymphocytes in cancer patients is decreased,the abnormal rates of lymphocyte subsets in the three kinds of cancer patients are higher than those in healthy volunteers,the lymphocyte subsets of different kinds of cancers perform different characteristics.

Objective To compare the curative effect of transcatheter arterial chemoembolization (TACE) combined with microwave ablation (MWA) with that of simple TACE in treating large liver cancers.Methods A computer-based search assisted by manual searching for TACE+MWA vs simple TACE clinical control trials for large liver cancers was conducted.The patient survival,tumor response and complications were enrolled in the scope of analysis.Results A total of 16 papers met the inclusion criteria,which included 1199 patients in total.Meta-analysis indicated that one-,2-and 3-year survival rates of TACE+MWA group were better than those of simple TACE group,and the differences between the two groups were statistically significant (P＜0.01).The complete response (CR) rate and partial response (PR) rate of TACE+MWA group were higher than those of simple TACE group,and the differences between the two groups were statistically significant (P＜0.01).The stable disease (SD) rate and progressive disease (PD) rate of TACE+MWA group were lower than those of simple TACE group,and the differences between the two groups were statistically significant (P＜0.01).Conclusion For the treatment of large liver cancers,TACE +MWA is superior to simple TACE.(J Intervent Radiol,2017,26:225-231)

Objective To make an interpretation for the time-related evolving process of magnetic resonance imaging (MRI) signal of hepatic tumors after microwave ablation (MWA) treatment.Methods A total of 56 patients with malignant hepatic tumors (56 lesions in total) were enrolled in this study.Upper abdominal MRI plain scan and enhanced scan were performed in all patients at the second day,one month and 6 months after MWA treatment.The MRI signal features of ablation zones at different time points on T1WI,T2WI,DWI as well as on contrast-enhanced T1WI were documented,and the judgment of whether there was tumor recurrence was made.Results Two days after MWA,the ablation zone was manifested as target-like structure on T1WI and T2WI,which was characterized by central high signal ablation zone with low signal band around on T1WI and low signal ablation zone surrounded by high signal band on T2WI.One and 6 months after MWA,the volume of ablation area was atrophied,the target-like structure could still be observed on T1WI and T2WI,and the signal of ablation zone became intensified.Contrast-enhanced MRI revealed that abnormal high perfusion sign could be observed around the ablation zone,and on MRI scans performed at two days,one and 6 months after MWA,the ablation zone showed no enhancement.DWI indicated that two days after MWA the signal around the ablation zone was heightened,which decreased gradually in one and 6 months after MWA.Conclusion The signal of the ablation zone of hepatic tumor after MWA is evolving over time.Correct interpretation of MRI signal of ablation zone is helpful for the judgment of curative effect and for the making of therapeutic plan.

Objective To evaluate the clinical effect and safety of oxycodone in the anesthesia for percutaneous microwave ablation (PMWA) in liver cancer when the scope of ablation involving liver capsule.Methods Thirty-eight patients scheduled for percutaneous microwave ablation of liver cancer abutting capsule, including 32 males and 6 females, aged 41-75 years, with ASA grade Ⅰ or Ⅱ.Patients were randomly divided into 2 groups:oxycodone group (group O,n=20) and fentanyl group (group F, n=18).Before the puncture, a loading dose of oxycodone 0.1 mg/kg was given intravenously in group O, a loading dose of fentanyl 1 μg/kg was given intravenously in group F.After successful puncture, both groups were induced by Propofol 1.5 mg/kg, followed by Propofol infusion at 4-7 mg·kg-1·h-1 in two groups.The changes of MAP, HR, SpO2 and RR before, during and after operation were recorded.Body movement and respiratory depression were recorded.The total amount of propofol,the postoperative recovery time, postoperative nausea and vomiting, and postoperative 4 h VAS scores were recorded.Results There was no significant difference in general condition and intraoperative condition of ablation operation between the two groups.The incidences of respiratory depression and body movement in group F were significantly higher than those in group O.There was no significant difference in the incidences of postoperative nausea and vomiting between the two groups.VAS score 4 h after operation in group F [(3.9±2.0) score] was significantly higher than that in group O [(1.7±0.9) score] (P＜0.01).There was no significant difference in HR between the two groups at each point.Compared with before surgery, the MAP during surgery in group F was significantly increased (P＜0.05),the RR during surgery in groups F and O were significantly lower (P＜0.01 or P＜0.05).The RR during surgery in group F was significantly lower than that in group O(P＜0.05),but there was no significant difference at the other points between the two groups.Conclusion Oxycodone can be used safely and effectively for percutaneous microwave ablation of liver cancer when the scope of ablation involving liver capsule.It has lower incidence of respiratory depression, effectively alleviates intraoperative pain and reduces postoperative pain.

Viruses (e.g. Human immunodeficiency virus, Human simplex virus and Prototype foamy virus) are obligate intracellular parasites and therefore depend on the cellular machinery for cellular trafficking. Bovine foamy virus (BFV) is a member of the Spumaretrovirinae subfamily of Retroviruses, however, details of its cellular trafficking remain unknown. In this study, we cloned the BFV gag gene into prokaryotic expression vector pET28a and purified the denaturalized Gag protein. The protein was used to immunize BALB/c mouse to produce antiserum, which could specifically recognize the BFV Gag protein in BFV-infected cells through western blot assay. Additionally, these results demonstrated that both the optimal and suboptimal cleavage of Gag protein occur in BFV-infected cells. Subsequently, the Gag antiserum was used to investigate subcellular localization of BFV. In immunofluorescence microscopy assays, colocalization microtubules (MTs) and assembling viral particles were clearly observed, which implied that BFV may transport along cellular MTs in host cells. Furthermore, MTs-depolymerizing assay indicated MTs were required for the efficient replication of BFV. In conclusion, our study suggests that BFV has evolved the mechanism to hijack the cellular cytoskeleton for its replication.

Objective: To investigate the survival status and influencing factors of HIV/AIDS patients after receiving highly active antiretroviral therapy（HAART）in Shangluo,Shaanxi Province,so as to provide evidence for improving the effect of HAART. Methods: HIV/AIDS patients who received HAART for the first time in Shangluo from 2010 to 2018 were investigated. Life table method was used to analyze the survival rate,mortality rate and median survival time of the subjects. A proportional hazards model was used to analyze the influencing factors for the survival time of HIV/AIDS patients. Results: A total of 286 HIV/AIDS patients were collected,and 27 of them died of AIDS. After HAART,the 1-year,cumulative survival rates of less than 1 year,4 years and 8 years were 93.95%,89.71% and 88.39%,respectively. The results of multivariate proportional hazards regression analysis showed that the patients aged 30 years when first received HAART had higher risk of death than those aged 18-29 years（RR：4.208-24.095,95%CI：1.219-79.491）;patients with AIDS had higher risk of death than those with HIV（RR=38.590, 95%CI：15.451-96.382）;patients by homosexual transmission（RR=3.425,95%CI：1.385-8.470）and non-sexual transmission（RR=10.299,95%CI：3.602-29.446）had higher risk of death than those by heterosexual transmission;patients with baseline CD4+T lymphocytes number of 200/μL and more（RR：0.133-0.170,95%CI：0.048-0.604）had lower risk of death than those with less than 200/μL. Conclusions The survival rate of HIV/AIDS patients in Shangluo after receiving HAART is relatively high. Age at the start of treatment,course of disease,route of infection and the number of CD4+T lymphocytes at baseline are the influencing factors of survival time.

Objective To investigate the difference of Alzheimer-associated neuronal thread protein ( AD7c-NTP) level and related factors among different symptom types of schizophrenia. Methods The con-centrations of AD7c-NTP in urine of 30 patients with positive symptoms,46 patients with negative symptoms and 24 controls were detected by enzyme linked immunosorbent assay( ELISA) . Positive and negative symp-tom scale ( PANSS) was used to assess schizophrenia patients. The correlation analysis was conducted be-tween the urine AD7c-NTP and demographic factors. Results The level of AD7c-NTP in urine of patients with negative symptoms((0. 88±0. 93) ng /ml)was higher than that in the patients with positive symptoms ((0. 50±0. 22)ng/ml,P<0. 05). The level of AD7c-NTP of in urine female patients((1. 16±1. 12)ng/ml) was higher than that in the male patients((0. 57± 0. 49)ng/ml,P<0. 01). AD7c-NTP levels in patients with a course of disease of more than 100 months((0. 96±0. 96)ng/ml) were higher than those in patients with a course of disease of less than 100 months((0. 60±0. 59)ng/ml,P<0. 05). The level of AD7c-NTP in pa-tients over 35 years old((0. 94±0. 96)ng/ml) were higher than that in patients under 35 years old((0. 62±0. 62)ng/ml,P<0. 05). The level of AD7c-NTP in patients with MMSE score of 0-22 points((0. 92±0. 80) ng/ml) were higher than that in patients with score of 23-29 points((0. 62±0. 74)ng/ml,P<0. 05). Before admission(at least 2 months),the level of AD7c-NTP in patients without persisting in taking drugs((0. 99± 0.95)ng/ml) was higher than that in patients with persisting in taking drugs((0. 62±0. 65)ng/ml,P<0. 05). The level of AD7c-NTP in schizophrenic patients was positively correlated with age and course of dis-ease( r=0. 29,0. 26,P<0. 05) ,and negatively correlated with smoking history and mini-mental state exami-nation( MMSE) ( r=-0. 13,-2. 41,P<0. 05) . Conclusion There is a difference in AD7c-NTP levels be-tween patients with positive and negative symptoms of schizophrenia. Gender,age,course of disease and anti-psychotics are important factors that affect AD7c-NTP levels in patients with schizophrenia.

OBJECTIVETo analyze the mean population intake of salt in Chinese adults in 2010-2012.

METHODSData were from the Chinese Nutrition and Health Surveillance in 2010-2012. The samples were selected through the method of probability proportion to size (PPS). The study objects were 55 531 adults aged 18 and over from 150 sites in 31 provinces, autonomous regions or municipalities in China. The information of oil, salt and other condiments for household was from the 3 d food weighed record. The average of salt intake for individuals was calculated based on the energy percentage in one family. The results presented the level of salt intake (x ± Sx) by analyzing the different demography characteristics. The results were calculated using complex weighting by the population data from National Bureau of Statistics in 2009.

RESULTSThe intake of salt was (9.6 ± 0.3) g/d and it was higher in men ((10.4 ± 0.4) g/d) than that in women ((8.8 ± 0.3) g/d). The intake in the age group of 40-49, 50-59 and 60-69 was (9.9 ± 0.5) g/d, (10.3 ± 0.4) g/d and (9.9 ± 0.3) g/d, respectively. The adults in rural ((10.2 ± 0.3) g/d) had a higher salt intake than that of urban ((9.0 ± 0.5) g/d). An average of salt intake was increased gradually in big city ((7.9 ± 0.3) g/d), medium /small city ((9.2 ± 0.6) g/d) , general rural ((9.9 ± 0.4) g/d) and poor rural ((10.8 ± 0.7)g/d).

CONCLUSIONThe mean salt intake among Chinese adults was still in a very high level. Something should be done to reduce the salt intake for the government and policy-makers.
