Objective To evaluate the value of positive 99Tcm-MIBI tumor imaging for thyroid cancer diagnosis. Methods Fifty four suspected thyroid cancer patients underwent 99Tcm-O4 and 99Tcm-MIBI combined imaging procedure. The imaging data were confirmed by pathological findings. Results All the 54 cases had single throid nodules, and 25 of which were pathologically malignant. Fifty two cases of nodules were detected by the 99Tcm O4 thyroid static imaging, including 2 hot nodules,4 warm nodules, 10 cool nodules and 36 cold nodules;2 cases were negative by the imaging. Of the 25 malignant thyroid nodules, 16 nodules were visible by 99Tcm-MIBI uptake and were cold nodules;29 exhibited benign thyroid nodules,of which 15 could be seen by 99Tcm-MIBI uptake,including 1 warm nodules,2 cool nodules and 12 cold nodules. The sensitivity, specificity of the combined imaging of 99Tcm O4 and 99Tcm-MIBI were 64. 00% ( 16/25 ) and 48. 28% (14/29). No significant difference was found for the positivity between benign nodules and malignancy nodules by 99Tcm-MIBI tumor imaging ( χ2 = 0. 83, P ＞ 0. 05 ). Conclusion 99Tcm-MIBI tumor imaging is not specific for the diagnosis of thyroid malignancy.

Objective To evaluate the effect of BML?111 on ventilator?induced lung injury in rats. Methods Forty?eight healthy male Sprague?Dawley rats, weighing 200-250 g, aged 6-8 weeks, were randomized into 6 groups ( n=8 each) using a random number table: control group ( C group) , low tidal volume (VT) group (LVTgroup), high VT group (HVTgroup), low dose BML?111 group (BL group), high dose BML?111 group ( BH group) , and BML?111 plus BOC?2 ( lipoxin A4 receptor antagonist) group ( BOC?2 group) . Group C kept spontaneous breathing after tracheotomy, and received no mechanical venti?lation. The rats in the other 5 groups were mechanically ventilated ( respiratory rate 80 breaths∕min, frac? tion of inspired oxygen 21%, positive end?expiratory pressure 0) . The VT was 6 ml∕kg in group LVT , or 20 ml∕kg in HVT, BL, BH and BOC?2 groups. BML?111 0?1 and 1?0 mg∕kg were injected intraperitoneally during ventilation in BL and BH groups, respectively. In group BOC?2, BOC?2 50 μg∕kg was injected in?traperitoneally before ventilation, and BML?111 1?0 mg∕kg was injected intraperitoneally during ventilation. Arterial blood samples were collected at 4 h of ventilation, arterial oxygen partial pressure ( PaO2 ) was de?termined. Then animals were sacrificed by exsanguination. Bronchoalveolar lavage fluid ( BALF) of the left lung was collected for determination of neutrophil count, and the level of neutrophil was calculated. The right lung tissue specimens were obtained for microscopic examination, and for determination of wet∕dry lung weight ratio ( W∕D ratio ) , myeloperoxidase ( MPO ) activity, and contents of malondialdehyde ( MDA) , monocyte chemoattractant protein?1 ( MCP?1) , tumor necrosis factor?alpha ( TNF?α) , interleu?kin?1beta ( IL?1β) and IL?6. Results Compared with group C, PaO2 was significantly decreased, and the level of neutrophil in BALF, W∕D ratio, MPO activity, and contents of MDA, MCP?1, TNF?α, IL?1β and IL?6 were increased in group HVT ( P<0?05) , and no significant change was found in the variables mentioned above in group LVT ( P>0?05) . Compared with group HVT , PaO2 was significantly increased, and the level of neutrophil in BALF, W∕D ratio, MPO activity, and contents of MDA, MCP?1, TNF?α, IL?1β and IL?6 were decreased in group BH, and the contents of TNF?α, IL?1βand IL?6 were significantly decreased ( P<0?05) , and no significant change was found in the other variables in group BL ( P>0?05) . Compared with group BH, PaO2 was significantly decreased, and the level of neutrophil in BALF, W∕D ratio, MPO activity, and contents of MDA, MCP?1, TNF?α, IL?1β and IL?6 were increased in group BOC?2 (P<0?05). The pathological changes were significantly attenuated in group BL as compared with HVT and BOC?2 groups. Conclusion BML?111 can attenuate ventilator?induced lung injury in rats, and activated lipoxin A4 receptors are involved in the mechanism.

Objective To evaluate the effect of BML-111 on NF-κB pathway during acute lung injury induced by hemorrhagic shock and resuscitation in rats.Methods Thirty-two adult male Sprague-Dawley rats,weighing 200-250 g,were randomly divided into 4 groups (n =8 each) using a random number table:sham operation group (group S),hemorrhagic shock and resuscitation group (group HSR),BML-111 group,and BML-111 + BOC-2 (lipoxin A4 receptor antagonist) group (group BOC-2).The animals were anesthetized with intraperitoneal pentobarbital sodium.Hemorrhagic shock was induced by blood letting and maintained for 30 min.The animals were then resuscitated for 30 min by infusion of the shed blood and lactated Ringer's solution.In group BOC-2,BOC-2 (50 μg/kg) was injected intraperitoneally before blood letting.In BML-111 and BOC-2 groups,BML-111 (1 mg/kg) was injected intraperitoneally at the beginning of resuscitation.The rats were sacrificed at 2 h after the end of resuscitation and lungs were removed for determination of pathological changes,myeloperoxidase (MPO) activity,intercellular adhesion molecule-1 (ICAM-1) expression (by immunohistochemistry),tumor necrosis factor-alpha (TNF-α) content (by ELISA),and NF-κB p65 and IκB-α expression (by Western blot).Results Compared with group S,the MPO activity,ICAM-1 expression,and TNF-α content were significantly increased,NF-κB p65 expression was up-regulated,and IκB-α expression was down-regulated in group HSR.Compared with group.HSR,the MPO activity,ICAM-1 expression,and TNF-α content were significantly decreased,NF-κB p65 expression was down-regulated,IκB-α expression was up-regulated,and pathological changes of lung were attenuated in group BML-111.Compared with group BML-111,the MPO activity,ICAM-1 expression,and TNF-α content were significantly increased,NF-κB p65 expression was up-regulated,and lκ:B-α expression was down-regulated,and pathological changes of lung were aggravated in group BOC-2.Conclusion BML-1 11 inhibits activation of NF-κB pathway and inflammatory responses,thus mitigating acute lung injury induced by hemorrhagic shock and resuscitation in rats.

Objective To investigate the incidence of radioactivity uptake in thymus combined with serum thyroglobulin (Tg) increase in differentiated thyroid cancer (DTC) patients after high-dose 131I treatments,in order to discuss the mechanism of thymus iodine uptaking and Tg increasing.Methods Retrospective analysis of the laboratory examinations and 131Iwhole body scan (131I-WBS) images in 316 DTC patients were performed.The radioactivity uptake in thymus and the Tg level were observed.Results Among 316 patients (total 735 case-times),4 patients of 5 cases-times 131I-WBS showed radioactivity uptake in thymus,accounting for 0.68％ (5/735).All the radioactivity uptake in thymus were found by posttreatment 131I whole body scan (Rx-WBS) and after the second radioactive iodine treatment.For 1 of 4 patients,Rx-WBS still showed thymic uptake 131I after the third radioactive iodine treatment.The serum Tg increased in 3 patients (4 caestimes Rx-WBS) of radioactivity uptake in thymus with the Tg level before Rx-WBS was 13.80 μg/L,＞300.00 μg/L,16.40 μg/L,20.60μg/L,respectively.Conclusion In order to avoid the inappropriate administration of radioiodine therapy,thymic uptake should be identified carefully in DTC patients whose radioactivity uptake is only found at the upper mediastinal and combined with serum Tg increase.

Objective To evaluate the effect of lipoxin A4 receptor agonist BML-111 on acute lung injury induced by hemorrhagic shock and resuscitation in rats.Methods Thirty-two healthy male Sprague-Dawley rats,aged 6-8 weeks,weighing 200-250 g,were randomized into 4 groups (n =8 each) using a random number table:sham operation group (S group),hemorrhagic shock/resuscitation group (HSR group),BML-111 group,and BML-111 plus BOC-2 (lipoxin A4 receptor antagonist) group (BOC-2 group).The animals were anesthetized with 2％ pentobarbital sodium 80 mg/kg,tracheostomized and mechanically ventilated.Left common carotid artery was cannulated for blood-letting and fluid infusion.Hemorrhagic shock was induced according to the method described by Kochanek et al.MAP was reduced to 35-45 mmHg and maintained at this level for 30 min.The animals were then resuscitated for 30 min with infusion of the blood withdrawn and lactated Ringer' s solution 2 times the volume of blood withdrawn.In BML-111 and BOC-2 groups,BML-111 (1 mg/kg) was injected intraperitoneally at the beginning of resuscitation.In BOC-2 group,BOC-2 (50 μg/kg) was injected intraperitoneally before blood-letting.The rats were sacrificed at 2 h after completion of resuscitation.Bronchoalveolar lavage fluid (BALF) was collected for determination of neutrophil count.Lungs were excised for microscopic examination of the pathological changes and for determination of wet/dry lung weight ratio (W/D ratio),contents of interleukin-1 (IL-1β) and IL-6,and phosphorylation of mitogen-activated protein kinase (MAPK).Results Compared with group S,the neutrophil count in BALF,W/D ratio,contents of IL-1β and IL-6,and phosphorylation of MAPK were significantly increased in HSR group (P ＜ 0.05).The neutrophil count in BALF,W/D ratio,contents of IL-1β and IL-6,and phosphorylation of MAPK were significantly lower in BML-111 group than in HSR group,and higher in BOC-2 group than in BML-111 group (P ＜ 0.05).Conclusion BML-111 can attenuate acute lung injury induced by hemorrhagic shock and resuscitation in rats and inhibition of activation of MAPK pathways and reduction of inflammatory responses in lung tissues are involved in the mechanism.

Objective To assess the risk of secondary transmission induced by imported malaria in Jiangxi Province，so as to provide the evidence for adjustment of malaria surveillance strategies in the key groups and areas. Methods The Delphi method was used to establish the secondary transmission risk indicator system and the weight of each index was obtained. The data of malaria prevalence，vector distribution and intervention capacity were collected in 100 counties of Jiangxi Province from 2012 to 2015. The transmission potential index（TPI），intervention capacity index（ICI），and malaria risk index（MRI）were calculated for each county. The risk map was drawn with GIS software. Results The top ten counties with highly potential risk indicators were Linchuan District（2.131），Xinzhou District（1.609），Jiujiang County（1.404），Zhanggong District（1.365）， Fengcheng City（1.225），Qingshanhu District（1.184），Yudu County（1.171），Dingnan County（1.018），Xunyang District（1.015）and Zhushan District（1.006）. The high risk areas were mainly distributed in the regions of the capitals of their prefectures and in counties with more floating population. Conclusions There are the risk of the secondary transmission induced by imported malaria in Jiangxi Province. The high risk of the secondary transmission is shown in the areas with more floating population and weaker intervention capacity.

Objective: To analyze the effect of acupuncture versus hormone replacement therapy (HRT) for premature ovarian insufficiency (POI). Methods: China National Knowledge Infrastructure (CNKI), Wanfang Academic Journal Full-text Database (Wanfang), Chongqing VIP Database (CQVIP), China Biology Medicine Disc (CBM), Web of Science, Cochrane Library, PubMed, and Excerpta Medica Database (EMBASE) were searched up to January 31st, 2019 to identify randomized controlled trials (RCTs) evaluating the effect of acupuncture for POI. The primary outcome was the level of basal serum follicle- stimulating hormone (FSH). Secondary outcomes included serum levels of luteinizing hormone (LH), estradiol (E2) and anti-Müllerian hormone (AMH). Two authors extracted data independently and assessed the risk of bias and the methodological quality using the Cochrane's tool. Meta-analysis was conducted by RevMan version 5.3. Results: Eight eligible RCTs with a total of 496 POI patients were included in the meta-analysis. The pooled results showed that there was a significant reduction in the basal serum FSH level (MD=-5.82, 95％CI:-9.76 to -1.87, I2=82％, P=0.004) and a remarkable elevation in the basal E2 level (SMD=0.93, 95％CI: 0.34 to 1.52, I2=88％, P=0.002) in the acupuncture group when compared with the control. Subgroup analysis showed that compared with HRT, a significant decrease in the FSH level was observed in both acupuncture alone (MD=-4.53, 95％CI:-8.96 to -0.10, I2=73％, P=0.04) and acupuncture plus HRT (MD=-9.60, 95％CI:-17.60 to -1.61, I2=50％, P=0.02), while a remarkable elevation of E2 was only found in acupuncture plus HRT (SMD=1.43, 95％CI: 1.03 to 1.82, I2=0％, P<0.00001). There was no significant difference in the LH level between acupuncture and HRT (MD=-3.16, 95％CI:-9.41 to 3.10, I2=0％, P=0.32), only one trial reported AMH, and no significant difference was found between acupuncture and HRT. Conclusion: The present study indicated that acupuncture had an advantage over HRT in reducing serum FSH level and increasing serum E2 level in women with POI. However, evidence supporting the finding is limited due to the small sample size, potential methodological flaws and significant heterogeneity. Hence, this conclusion still needs to be verified by high-quality RCTs.
