Objective To investigate the clinical efficacy of combined acupuncture and medicine plus ultrashort wave diathermy in treating post-stroke complicated urinary tract infection.Methods One hundred and twenty patients with post-stroke complicated urinary tract infection were randomly allocated to groups A, B and C, 40 cases each. Group A received acupuncture, ultrashort wave diathermy and treatment with anti-infective drugs; group B, ultrashort wave diathermy and treatment with anti-infective drugs; group C, treatment with anti-infective drugs alone. The clinical therapeutic effects and the recurrence rates were compared between the three groups.Results The total efficacy rate was 92.5% in group A, 90.0% in group B and 72.5% in group C. There was a statistically significant difference in the total efficacy rate between group A or B and group C (P<0.05). The recurrence rate was 8.1% in group A, 27.8% in group B and 31.0% in group C. There was a statistically significant difference in the recurrence rate between group A and group B or C (P<0.05).Conclusion Combined use of acupuncture and medicine plus ultrashort wave diathermy is an effective way to treat post-stroke complicated urinary tract infection.

Objective To observe the effects of immune acupuncture and moxibustion on the infection in hospital and the outcome of re-habilitation after stroke. Methods From January, 2014 to January, 2016, 100 patients following acute stroke were randomly divided into ob-servation group (n=50) and control group (n=50). The control group accepted routine medications, rehabilitation and acupuncture, while the observation group accepted acupuncture and moxibustion on Guanyuan (RN4), Qihai (RN6) and Zusanli (ST36) in addition. The nosocomi-al infection rate was recorded 90 days after treatment, and the T lymphocyte subsets, scores of Fugl-Meyer Assessment (FMA) and modified Barthel index (MBI) were measured before and after treatment. Results The nosocomial infection rate was 20% in the observation group, less than 42% in the control group (χ2=5.657, P<0.05). The contribution of CD3+ and CD4+ T lymphocytes, and the scores of FMA and MBI increased after treatment in both groups (t>2.463, P<0.05), and increased more in the observation group than in the control group (t>2.225, P<0.05). Conclusion Immune acupuncture and moxibustion therapy can reduce the incidence of nosocomial infection, and promote the func-tion of the immune system and outcome in patients after acute stroke.

Objective To investigate the effect of interventional therapy for Budd Chiari Syndrome(BCS). Methods 355 patients with BCS were examined with phlebography of inferior vena cava(PIVC) and percutaneous transhepatic hepatovenography(PTHV).The interventional procedures were based on the pathological changes of inferior vena cava(IVC) and main hepatic veins(MHVs).The procedures included PTA and/or stent placement of IVC,percutaneous transhepatic recanalization and dilation (PTHRD)of MHVs ,and percutaneous transjugular or transinferior vena cava recanalization and dilation with stent placement of MHVs(PTJRD and PTIRD ), percutaneous transhepatic recanalization or transinferior vena cava recanalization and dilation with stent placement of associated hepatic veins(AHVs). Results The success rate and recurrence rate were 96.0%(240/250) and 10.0 %(24/240), respectively, in PTA; the success rate was 91.4%(32/35 ) in PTHRD of MHVs; 90.0%(18/20 ) in PTJRD and PTIRD of MHVs , 100.0%(10/10) in PTJRD and PTIRD of AHVs; 90.0 %( 9/10 ) in PTA and stent placement plus PTHRD of AHVs. Severe complications occurred in 10 cases (2.8%). Conclusions Interventional therapy is simple, safe and effective for patients with some types of Budd Chiari Syndrome.

Objective? To analyze the root causes of fall in elderly patients, explore the corresponding countermeasures and combine the balance function and knee joint strengthening training to reduce the incidence of fall in elderly patients. Methods? First, the cause of fall of the patients in the department of rehabilitation from November 2014 to October 2016 were analyzed with the method of root cause analysis and retrospective analysis, and targeted corrective measures were formulated. The elderly patients fell between the time period from November of 2016 to October of 2017 and November of 2017 to October of 2018 were enrolled into the control group and observation group by convenience sampling. Corrective measures were formulated based on root cause analysis and action (RCA2) to prevent falls in the control group, on the basis of that balance function training combined with strengthening training of knee joint control were adopted to prevent fall in the observation group. The two groups were compared in terms of the differences in the incidence of fall, five times of sitting and standing test(FTSST), 10 meters maximum walking speed (10MWS), Berg Balance Scale(BBS)and Tinetti Gait Analysis (TGA). The incidence of fall in the department before the implementation of corrective measures based on RCA2(November 2014 to October 2016) and the time period of November 2016 to October 2018 which is after the implementation of RCA2 based corrective measures were compared. Results? After implementing the corrective measures, the fall rate of the elderly patients reduced from 2.0% to 0.9% with statistical difference (χ2=4.343, P=0.037). There was statistical difference (χ2=3.899, P=0.048) in terms of the incidence of fall between the observation group (4.24%) and the control group (0.64%). Before intervention, the two groups had no statistical difference in the FTSST, 10MWS, BBS and TGA(P＞0.05). In the control group, there was no statistical difference before and after intervention (P＞ 0.05); in the observation group, there was statistical difference before and after intervention (P＜0.05). After intervention, the observation group was better than the control group in the FTSST, 10MWS, BBS and TGA with statistical difference (P＜0.05). Conclusions? The comprehensive use of root cause analysis and intensive training of knee joint control and balance function training to manage elderly patients scientifically can effectively reduce the incidence of falls.

Objective: To explore the association between parental education level and time spent outdoors among children, so as to provide the scientific evidence for formulating policies of myopia prevention and control among children. Methods: The study was based on secondary analysis of data from outdoor intervention studies in Shanghai. The follow up period was from March to December 2018. It included control group children ( n =1 117) with complete questionnaire surveys, ocular examinations, and time spent outdoors. Generalized linear regression models and trend tests were used to analyze the effect of parental education level on time spent outdoors among children. Results: The median time spent outdoors was 76.4(59.7, 94.6) minutes. After adjusting for covariates including children s sex and age, generalized linear regression model suggested that there was no statistical significance between father s education level and outdoor activity time ( P >0.05). Compared with children whose mothers had a junior high school education or below, children whose mothers had high school/vocational high school education, college or above had shorter time spent outdoors ( β=-6.64, -8.84 , P <0.05). Trend tests revealed that time spent outdoors among children decreased with the increase of parental education level ( P trend <0.01). Conclusions The higher the education level of fathers or mothers, the shorter time spent outdoors of children. In addition to highlight outdoor activities at school, myopia prevention and control efforts should be focused on the role of parents in increasing children s outdoor activities.

BACKGROUND:Cervical rotation-traction manipulation is effective and safe in the treatment of cervical spondylotic radiculopathy,and has been widely used in clinical work.However,its effects on the biomechanics of cervical vertebra and intervertebral disc and the area of intervertebral foramen have not been systematically clarified. OBJECTIVE:Based on the finite element analysis technique,a relevant research and analysis were carried out to provide digital evidence for the mechanism of effect of cervical rotation-traction manipulation in the treatment of cervical spondylotic radiculopathy. METHODS:The CT image data of a volunteer with no neck diseases were selected as the finite element model material at its left-handed physiological limit position.The initial construction of the finite element model was completed by Mimics 19.0 software,Geomagic Studio 2013 software,Hypermash 14.0 software,and ANSYS Workbench 2020 R2 software,respectively.Based on the literature,the grid division of cervical structure and the assignment of elastic modulus and elastic coefficient were completed.Based on the previous work of the team,the mechanical effects of cervical rotation-traction manipulation were simulated on the model.Effects of cervical rotation-traction manipulation on the mechanical parameters of each vertebral body and intervertebral disc in C3-T1 segment and on the cervical lateral foramen area were analyzed. RESULTS AND CONCLUSION:(1)During cervical rotation-traction manipulation,the stress of bone structure was significantly higher than that of soft tissue such as intervertebral disc.(2)When operating the technique,the stress at the top of each cervical vertebra was higher,the stress at the bottom was lower,and the stress at the facet joint and transverse process was lower.The stress at the top of the intervertebral disc was lower,the stress at the bottom was higher,but the highest point of the intervertebral disc stress was outside the top.(3)In addition,after loading the lifting force,the projected area of the C6/C7 intervertebral foramen increased significantly compared with that before loading.(4)It is indicated that the cervical rotation-traction manipulation has the mechanical characteristics of changing the stress structure of the cervical spine itself,and can expand the C6/7 intervertebral cervical foramen area on the opposite side of the patient's cervical rotation,so as to achieve the purpose of treating cervical spondylotic radiculopathy.

AIM:To investigate the effect of vaccarin(VAC)on endothelial dysfunction in type 2 diabetes mellitus(T2DM),and to uncover the underlying mechanisms.METHODS:(1)C57BL/6 mice received intraperitoneal injection of streptozotocin and were fed with a high-fat diet(21.8 kJ/kg,60%of the energy source was fat)to construct a T2DM mouse model.Thirty mice were randomly divided into control,T2DM and T2DM+VAC groups,with 10 mice in each group.The mice in T2DM+VAC group were given 1 mg/kg VAC via oral gavage for 6 weeks,while those in control and T2DM groups were given the same volume of PBS.The mRNA and protein expression levels of BCL2-interacting pro-tein 3(BNIP3),PTEN-induced kinase 1(PINK1)and parkin in the thoracic aorta were detected by RT-qPCR and West-ern blot.(2)Human umbilical vein endothelial cells(HUVECs)were stimulated by high glucose(HG;35 mmol/L glu-cose).Mitochondrial membrane potential,autophagy and mitochondrial superoxide levels were detected using JC-1,acri-dine orange(AO)and MitoSOX staining,respectively.RESULTS:Compared with control group,the mRNA and protein levels of BNIP3,PINK1 and parkin were significantly increased in the thoracic aorta of T2DM mice(P<0.05).Compared with T2DM group,the mRNA and protein levels of BNIP3,PINK1 and parkin in the thoracic aorta were significantly re-duced in T2DM+VAC group(P<0.05).The results of JC-1,AO and MitoSOX staining showed that VAC attenuated the decrease in mitochondrial membrane potential and the increase in autophagy and mitochondrial superoxide levels in HG-in-duced HUVECs.Treatment with VAC also inhibited HG-mediated mitochondrial damage in HUVECs after BNIP3 overex-pression.The effect of miR-570-3p mimic on mitochondrial damage was similar to VAC.RT-qPCR and Western blot showed that both miR-570-3p mimic and VAC significantly reduced the mRNA and protein levels of BNIP3,PINK1 and parkin.In contrast,inhibition of miR-570-3p exhibited the opposite effects.CONCLUSION:Treatment with VAC alle-viated endothelial dysfunction in T2DM by inhibiting HG-induced mitochondrial dysfunction through miR-570-3p/BNIP3.

ObjectiveTo investigate the acceptance and influencing factors of manual hyperinflation (MIH) in patients with open sputum suction after tracheotomy, so as to provide reference for improving the acceptance of MIH for patients. MethodsBy convenience sampling, 140 patients with tracheotomy on open suction in Affiliated Hangzhou First People＇s Hospital, Zhejiang University School of Medicine from October 2016 to September 2018 were selected as participants in the study and the Self-Designed Questionnaire was used to study the acceptance towards MIH of the patients. Univariate analysis and Logistics regression analysis were conducted to analyze the influencing factors of the acceptance of patients on MIH. A total of 140 questionnaires were distributed, and 134 valid ones were collected. ResultsUnivariate analysis showed that there were statistical difference in age, gender, family support, duration of tracheotomy, whether the medical staff had explained the relevant knowledge of MIH, and whether the patients had experienced MIH on patients＇acceptance of MIH (P＜ 0.05). The above 6 statistically significant factors were analyzed by multivariate Logistic regression and the results showed that age, gender, duration of tracheotomy, whether the patients had experienced MIH before were the influencing factors of the patients＇ acceptance on MIH(P＜ 0.05). ConclusionsAge, gender, duration of tracheotomy, whether or not the patents have experienced MIH are independent impact factors for the patients＇ acceptance of MIH and the above factors can be the cut-in points of explanation and education in the process of MIH,so as to improve the patients＇ acceptance of MIH and promote recovery.

With the widespread use of CT scan in lung cancer screening,in clinical practice the detection rate of pulmonary ground-glass nodule(GGN),especially multiple GGNs,has become higher and higher.So far,the guidelines for the treatment of multiple pulmonary nodules mainly focus on the high-risk nodules,while there is no uniform guideline for the management of multiple high-risk GGNs.The main treatment strategies for GGNs include follow-up check and surgical resection.However,for patients who are unable to undergo or refuse to receive surgery,non-surgical therapies such as stereotactic body radiation therapy(SBRT),interventional ablation(such as radiofrequency ablation,micro wave ablation,cryoablation,etc.)can be considered.This article reviews the clinical management strategies and therapeutic evaluation of multiple pulmonary nodules,aiming to provide reference for the clinical management of multiple pulmonary nodules.
