Objective To explore the effect of acupuncture combined with facilitated technique on lower limb function and activities of daily living of stroke patients.Methods 120 stroke patients with lower limb palsy were divided into the group Ⅰ (treated with acupuncture combined with facilitated technique), group Ⅱ (treated with acupuncture), third group Ⅲ (treated with facilitated technique) and the group Ⅳ (treated with medicine). The lower limb function and ADL of four groups were evaluated with Functional Ambulation Classification (FAC), Fugl-Meyer Assessment (FMA), Modified Barthel Index (MBI) before and 10 weeks after treatment.Results The scores of FAC, FMA and MBI of all the groups improved significantly, but it was more significantly in the first group than the in other groups (P<0.01), in group Ⅰ, Ⅱ, Ⅲ than in group Ⅳ (P<0.01). The difference between the group Ⅱ and Ⅲ was insignificantly(P>0.05).Conclusion Acupuncture combined with facilitated technique can improve the lower limb function and activities of daily living of stroke patients more effectively.

Glucocorticoid receptors (GR) in the traumatized(left) hemisphere cytosol were decreased more significantly than those in both the control (right) hemisphere cytosol at 6h postinjury and normal brain tissue (P

Objective To report our experience of retroperitoneal laparoscopic extravascular stent placement for nutcracker syndrome.Methods The clinical data of 12 nutcracker syndrome patients (10 males and 2 females;mean age 26 years) who underwent retroperitoneal laparoscopic extravascular stent placement from March 2014 to Febuary 2016 were retrospectively reviewed.The main symptoms were gross hematuria in 8 patients(one with proteinuria)and flank pain was noted in 1 patient.Three male patients had left-sided secondary varicoceles.Ultrasonography and computed tomography showed the left renal vein clamped by the superior mesenteric artery and the aorta.The anteroposterior diameter of the left renal vein in the renal hilum was three-fold than the aortomesenteric area,and the peak velocity ratio of the aortomesenteric area was much faster than the renal hilum.Twelve patients underwent laparoscopic extravascular stent placement under general anesthesia.The preaortic fibrous tissue between the aorta and the superior mesenteric artery was released intraoperatively.Renal vein became fiat when the superior mesenteric artery was elevated.The 6-8 cm extravascular stent was set on the surface of the renal vein to prevent the compression.Results Stenting was successfully accomplished in all 12 patients.Mean operative time was 62 min (50-125 min),estimated blood loss was 35 ml(20-100 ml),and the hospital stay after operation was 8 days (6-12 days).Three patients had a transient orthostatic intolerance,and they were cured by conservative treatment.With a mean follow up of 14 months (5-30 months),symptoms of hematuria and flank pain resolved in 7/8 and 1/1,respectively.Varicoceles were cured in all three patients.One case got partial relief because of recurrent hematuria due to excessive exercise.Ultrasonography showed that extravascular stent was in the right place,and the angle between abdominal aorta and superior mesenteric artery became normal.The inner diameter of left renal vein was decreased,and the narrow segment was diminished in diameter meanwhile the blood outflow was smooth.Conclusions Retroperitoneal laparoscopic extravascular stent placement in the renal vein is a safe and effective approach for nutcracker syndrome.

Objective To retrieve,appraise and summarize the available evidence on management and prevention of implantable venous access port occlusion in adult patients.Methods We searched the BMJ best practice,UpToDate,Cochrane Library,Joanna Briggs Institute Library,Registered Nurses' Association of Ontario,National Guideline Clearinghouse,PubMed,EMbase,CNKI and CBM to collect literatures including guidelines,evidence summary,best practice information sheet,recommended practice,systematic review and consensus.Results Five references including one guideline,one systematic review,two evidence summaries,and one expert consensus were included.A total of eight items of best evidence were summarized with regard to syringe size,flush volume,flush technique and frequency of administration,choose of needleless connectors,management of mechanical occlusion,drug/mineral precipitation,and thrombotic occlusion.Conclusion Healthcare workers should regulate the standard of venous access port flushing and locking and manage catheter occlusion in a timely manner,to avoid adverse incidents like interruptions in treatment,bacteremia,and venous thrombosis.

Objective:To effectively quantify and evaluate the quality of different deformation registration algorithms, in order to enhance the possibility of implementing deformation registration in clinical practice.Methods:The Jacobian determinant mean (JDM) is proposed based on the Jacobian determinant (JD) of displacement vector field (DVF), and the Jacobian determinant error (DJDE) is introduced by incorporating the JD of the inverse DVF. The optical flow method (OF-DIR) and fast demons method with elastic regularization (FD-DIR) were tested on nasopharyngeal and lung cancer datasets. Finally, JDM and DJDE with the Jacobian determinant negative percentage (JDNP), inverse consistency error (ICE) and normalized mean square error (NMSE) were used to evaluate the registration algorithms and compare the differences evaluation indicators in different tumor images and different algorithms, and the receiver operating curve (ROC) was analyzed in evaluation.Results:In lung cancer, OF-DIR outperformed FD-DIR in terms of JDM, NMSE, DJDE and ICE, and the difference was statistically significant( z = -2.24, -4.84, t = 4.01, 6.54, P<0.05). In nasopharyngeal carcinoma, DJDE, ICE and NMSE of OF-DIR were superior to FD-DIR, and the difference was statistically significant ( t = 4.46, -7.49, z = -2.22, P<0.05), but there was no significant difference in JDM ( P>0.05). In lung cancer and nasopharyngeal carcinoma, JDNP of OF-DIR was worse than that of FD-DIR, and the difference was statistically significant ( z = -4.29, -4.02, P<0.01). In addition, DJDE is more specific and sensitive on ROC curve (AUC=0.77), and has different performance result for tumor images at different sites. Conclusions:The JDM and DJDE evaluation metrics proposed are effective for deformation registration algorithms. OF-DIR is suitable for both lung cancer and nasopharyngeal carcinoma, while the influence of organ motion on the registration effect should be considered when using FD-DIR.

In recent years, with the rapid development of life sciences, the use of laboratory fish in toxicology, genetics, developmental biology and medicine has increased dramatically, and they have gradually become important new model organisms. At the same time, the welfare of laboratory fish has also received increasing attention. Although the research level of experimental fish welfare is still in a relatively early stage compared to terrestrial experimental animals, developed regions such as Europe and America have established corresponding legal frameworks to safeguard the welfare of laboratory fish in research. This article elucidates the current developmental status of laboratory fish welfare, discusses the rationale behind the imperative to prioritize and enhance their welfare, deeply investigates factors influencing their welfare from the feeding stage and experimental stage. Moreover, it explores strategies for augmenting welfare standards, with the overarching aim of propelling the continual improvement of laboratory fish welfare in our country.

Objective:To analyze the dosimetric differences of volumetric modulated arc therapy (VMAT) plans for lung cancer caused by different dose calculation algorithms and radiation field settings and thus to provide a reference for designing clinical VMAT plans for lung cancer.Methods:This study randomly selected 20 patients with lung cancer and divided them into four groups of VMAT plans, namely, a group adopting two fields and two arcs based on the AAA algorithm (2F2A_AAA), a group employing two fields and two arcs based on the AXB algorithm (2F2A_AXB), a group using two fields and two arcs based on the MC algorithm (2F2A_MC), and a group adopting one field and two arcs based on the MC algorithm (1F2A_MC). Then, this study evaluated the target coverage, high-dose control, dose homogeneity index (HI), conformity index (CI), and organs at risk (OARs) of the plans using different algorithms and radiation field settings.Results:The planning target volume (PTV) results of two fields combined with two arcs (2F2A) of three groups using different algorithms are as follows. 2F2A_MC achieved better results in both D1% and V 95% (the relative volume of the target volume surrounded by 95% of the prescribed dose) of planning gross target volume (PGTV) than 2F2A_AAA (D1%: t=-2.44, P=0.03; V95%:z=-2.04, P=0.04) and 2F2A_AXB (D1%: t=2.34, P=0.03; z=-3.21, P < 0.01). 2F2A_AXB outperformed 2F2A_AAA ( z=-3.66, P < 0.01) and was comparable to 2F2A_MC in terms of the CI of PGTV. Regarding OARs, 2F2A_AXB and 2F2A_MC decreased the V5 Gy of the whole lung by 0.68% ( z=-2.69, P=0.01) and 3.05% ( z=-3.52, P < 0.01), respectively compared to 2F2A_AAA. 2F2A_AXB achieved a whole-lung Dmean of 1776.44 cGy, which was superior to that of 2F2A_MC ( t=2.67, P=0.02) and 2F2A_AAA ( t=8.62, P < 0.01). Compared to 2F2A_AAA and 2F2A_MC, 2F2A_AXB decreased the V20 Gy of Body_5 mm by 1.45% ( z=-3.88, P < 0.01) and 2.01% ( z=-3.66, P < 0.01), respectively. The results of the two groups with different field settings showed that 1F2A_MC was superior to 2F2A_MC in both the CI of PTV1 and the HI of PTV2 (CI: t=2.61, P=0.02; HI: z=-2.20, P=0.03). Moreover, 1F2A_MC increased the Dmean of the whole lung by 26.29 cGy compared to 2F2A_MC ( t=2.28, P=0.04). Conclusions:Regarding the design of VMAT plans for lung cancer, the MC algorithm is suitable for the target priority and the AXB algorithm is suitable for the OAR priority. When only the MC algorithm is available, it is recommended to choose 1F2A in the case of target priority and select 2F2A in the case of OAR priority.

Objective:To analyze the accuracy of lung ultrasound and chest X-ray in the diagnosis of neonatal pulmonary disease.Methods:We prospectively collected newborns that needed chest X-ray examination to diagnose pulmonary disease from twelve neonatal intensive care units across the country between June 2019 and April 2020.Each newborn was examined by lung ultrasound within two hours after chest X-ray examination.All chest X-ray and lung ultrasound images were independently read by a radiologist and a sonographer.When there was a disagreement, a panel of two experienced physicians made a final diagnosis based on the clinical history, chest X-ray and lung ultrasound images.Results:A total of 1 100 newborns were enrolled in our study.The diagnostic agreement between chest X-ray and lung ultrasound(Cohen′s kappa coefficient=0.347) was fair.Lung ultrasound(area under the curve=0.778; 95% CI 0.753-0.803) performed significantly better than chest X-ray(area under the curve=0.513; 95% CI 0.483-0.543) in the diagnosis of transient tachypnea of the newborn( P<0.001). The accuracy of lung ultrasound in diagnosing neonatal respiratory distress syndrome, meconium aspiration syndrome, pneumonia and neonatal pulmonary atelectasis was similar to that of chest X-ray. Conclusion:Lung ultrasound, as a low-cost, simple and radiation-free auxiliary examination method, has a diagnostic accuracy close to or even better than that of chest X-ray, which may replace chest X-ray in the diagnosis of some neonatal lung diseases.It should be noted that both chest X-ray and lung ultrasound can only be used as auxiliary means for the diagnosis of lung diseases, and it is necessary to combine imaging with the clinical history and presentation.
