Purpose: The aim of this study was to compare the effectiveness and outcomes of percutaneous ablation guided by ultrasonography (US) and computed tomography (CT) in colorectal liver oligometastases (CLOM). Methods: This study included patients with CLOM treated with percutaneous ablation from January 2008 to January 2021 in this observational study. Only lesions visualized on both CT and US images were further analyzed according to whether patients’ initial ablation treatments utilized US guidance or CT guidance. The Kaplan-Meier method was used to estimate local tumor progression (LTP)–free survival after propensity score matching (PSM). The LTP-free survival and treatment-related outcomes were compared between these two groups. Results: PSM identified 116 patients from each group, with 269 and 238 lesions in the USguided and CT-guided groups, respectively. US-guided ablation had a shorter average procedure time and lower cost than CT-guided ablation (27.54±12.06 minutes vs. 32.70±13.88 minutes, P=0.003; $2,175.13±618.17 vs. $2,455.49±710.25, P=0.002). For patients >60 years of age, the cumulative LTP rate at 1 year was lower in the US-guided group than in the CT-guided group (17.8% vs. 25.1%, P=0.038). For patients with perivascular liver lesions, the cumulative LTP rate at 1 year was lower in the US-guided group (14.4% vs. 28.2%, P=0.040). Conclusion For patients whose age is >60 years or who have perivascular liver lesions, USguided ablation is better than CT-guided ablation, with a shorter treatment time and lower costs when both ablation methods are feasible for patients.

Abstract: To investigate the changes of cerebral blood flow(CBF) in patients with type 2 diabetes mellitus(T2 DM) and its correlation with cognitive function and olfactory impairment. Methods: Cognitive function assessment and smell identification test were performed on 83 patients with T2 DM and 62 healthy controls(HC). Three-dimensional pseudo-continuous arterial spin labeling(3 D-pcASL) head images were collected from the two groups. CBF values of the cerebral cortex were compared between the patients and HC after the postprocessing. Correlations between the CBF values and cognitive function assessment and between the CBF values and smell identification test scores were analyzed as well. Results: Compared to the HC, Chinese smell identification test(CSIT), montreal cognitive assessment(MoCA), digit span test(DST), verbal fluency test(VFT) scores were lower in T2 DM patients(P<0.05).The CBF of the bilateral middle frontal gyrus in T2 DM patients was higher than that in HC group(P<0.001). The CBF of the bilateral gyrus rectus and olfactory cortex in T2 DM patients was lower than that in HC group(P<0.001). Conclusion The cognitive and olfactory function of patients with T2 DM decreased. Patients with T2 DM have abnormal perfusion in the bilateral middle frontal gyrus, gyrus rectus and olfactory cortex, revealing that CBF changes in these brain regions may be one of the causes for cognitive impairment and olfactory dysfunction in T2 DM.

Objective:To provide reference for relevant aeromedical support by analyzing the changes of flight fatigue and sleep quality of helicopter pilots before and after training.Methods:The cluster sampling method was adopted. The fatigue self-assessment questionnaire was issued to 90 helicopter pilots to measure the fatigue index. Video scintillator was used to measure the critical flick fusion frequency (CFF). Combined with the fatigue index, flight fatigue status before and after flight trainings was evaluated. Pittsburgh sleep quality index (PSQI) was used to measure the sleep index and sleep factors before and after trainings, and statistical difference was analyzed between aircraft types and training phrases.Results:One hundred and eighty questionnaires were given out in 2 surveys and the effective rate was 100.0%. ①There was no statistical difference in fatigue index and sleep index between armed helicopter (55 cases) and transport helicopter (35 cases) pilots before the trainings of the year ( P>0.05). ②The self-reported fatigue , mental fatigue , total score and PSQI of high-performance armed helicopter pilots were higher than those of general-performance armed helicopter pilots before training ( t=2.227-3.693 , P<0.01 or 0.05). However , there was no statistical difference in CFF. ③The physical fatigue , mental fatigue , total score of helicopter pilots increased after trainings ( t=2.383-3.217 , P<0.01 or 0.05) , and CFF was significantly reduced ( t=3.695 , P<0.01). After trainings , the pilots′ sleep quality , sleep latency , sleep time , sleep efficiency , sleep disorders , sleep medications and daytime function were significantly different from those before trainings ( t=2.238-21.095 , P<0.01 or 0.05) , and PSQI significantly increased ( t=2.050 , P<0.05).④The self-reported fatigue , physical fatigue , mental fatigue , fatigue score of armed helicopter pilots increased ( t=2.019-3.297 , P<0.01 or 0.05) and CFF significantly reduced after trainings ( t=3.926 , P<0.01). Their sleep efficiency , sleep disorders and daytime function were significantly different from those before trainings ( t=12.274 , 4.338 , 2.186 , P<0.01 or 0.05) , and PSQI significantly increased ( t=2.975 , P<0.01). Conclusions:Flight training has a significant effect on flight fatigue and sleep quality of helicopter pilots. It is important to pay attention to the effective recovery of flight fatigue after flight training.

Objective To evaluate the long-term therapeutic effect of Ruangan pills on advanced schistosomiasis combined with ascites. Methods The data of 54 advanced schistosomiasis patients with ascites were collected,and the patients were divid-ed into two groups namely a treatment group and a control group according to whether taking Ruangan pills. The effective rates,im-provement status of symptoms and levels of serum albumin(ALB)and hyaluronic acid(HA)of the two groups were compared. Re-sults The effective rates of the treatment group and control group were 92.59%and 44.44%,respectively,and the difference be-tween them was statistically significant(P<0.05). After the treatment for 9 and 12 months,the percentages of patients without as-cites and patients with symptom improvement in the treatment group were 77.78%and 92.59%,92.59%and 96.30%,respective-ly,while those in the control group were 29.63%and 37.00%,48.15%and 51.85%,respectively,and the differences between the two groups by different time were all statistical significant(all P<0.05). After the treatment for 9 months,the percentages of patients with the normal levels of ALB and HA were 88.89% and 59.26%,while those in the control group were 40.74% and 14.81%,respectively,and the differences between the two groups were statistically significant(both P < 0.05). Conclusion The long-term treatment of Ruangan pills can not only improve clinical symptoms but also control the ascites recurrence,however, the therapeutic effect and the recurrence rate of ascites in longer-term still need further observation.

Objective To explore the efficacy,mechanism and safety of silibinin combined with Ruangan pills(a Chinese herbal preparation)in the treatment of schistosomiasis liver fibrosis. Methods A total of 200 patients with schistosomiasis liver fibrosis were randomly divided into a control group and a treatment group,and 100 patients in each group were respectively admin-istered with oral silibinin alone and oral silibinin combined with Ruangan pills,respectively. The curative effects in the two groups were evaluated in 3 months,6 months,9 months and 12 months respectively. Results The common five clinical symptoms of schistosomiasis liver fibrosis patients significantly relieved in the treatment group 12 months after the therapy,and the total effi-ciency reached more than 75%,which were significantly higher than that in the control group. In the treatment group and the con-trol group,there was no improvement in the liver B ultrasonic classification 3 months and 6 months after the therapy(P>0.05);however,in 9 months and 12 months,the liver B ultrasonic classification in the treatment group was better than that in the control group(P<0.05,P<0.01,respectively). For the four serum indexes of liver fibrosis,there was no significant differences between the two groups in 3 months,however,in 6 months,9 months,and 12 months,there was a significant improvement in the treat-ment group compared with the control group. There were no obviously adverse effects in two groups. Conclusion Silibinin com-bined with Ruangan pills has a better curative effect in the treatment of schistosomiasis liver fibrosis.

Objective To evaluate the effects of different concentrations of sevoflurane anesthesia on longterm learning and memory abilities in neonatal rats.Methods Twenty-seven neonatal Sprague-Dawley rats of both sexes,aged 7 days,weighing 12-20 g,were randomly assigned into 3 groups (n =9 each):control group (C group),2％ sevoflurane group (S1 group) and 3％ sevoflurane group (S2 group).Groups C,S1 and S2 inhaled air,2 ％ sevoflurane and 3 ％ sevofluran for 4 h,respectively.The neonatal rats were reared to 35 days old and underwent open field test,to 36 days old and underwent Morris water maze test,and to 42 days old and underwent continuous multiple-trail inhibition avoidance training.Results Open field test:There was no significant difference in the movement time,movement speed and the time the animals spent in the central square among the 3 groups (P ＞ 0.05).Morris water maze test:Compared with C group,the looking for platform latency on 2nd-5th days in S2 group and on 2nd-3rd days in S1 group was significantly prolonged,and the percentage of time of staying at the platform quadrant was decreased in S1 and S2 groups (P ＜ 0.05 or 0.01).The looking for platform latency on 3rd4th days in S2 group was significantly longer than that in group S1 (P ＜ 0.05).Continuous multiple-trail inhibition avoidance training:The latency detected at 24 h after training was significantly shorter in S1 and S2 groups than in group C (P ＜ 0.05),and in group S2 than in S1 group (P ＜ 0.05).Conclusion Sevoflurane anesthesia decreases the long-term learning and memory function in neonatal rats in a concentration-dependent manner.

Fluorescence resonance energy transfer(FRET)is increasingly used to study inter-and intramolecular interactions in living cells.Since being proportional to the concentration of the donor-acceptor complex.FRET value must be normalized to exclude the influence of the ratio and the concentration of donor and acceptor for comparison.Different from the intra.molecular FRET which is simplified by the fact that the COncentration of the donor is equal to that of the acceptor,the inter-molecular FRET is usually too complicated for most existing measurements to quantify exactly.We deduced the exact proportion of the donor-acceptor complex based on a unique characteristic of homodimer,a special kind of the intermolecular interaction,developed an exact quantification measurement of the FRET.We proved the novel method Can generate more reliable estimation of FRET value by comparison with other methods using a homodimer,estrogen receptor alpha(ERa),as a FRET pair.
