In recent 30 years, it was approved that extracorporeal shock wave (ESW) is effective on musculoskeletal disorders. Hypertonia is a common complication in patients suffered from central nervous system lesion. Recently, there were several literatures report hypertonia can be treated with ESW. This paper reviewed the research in basic principle of ESW and its use on hypertonia.

OBJECTIVETo explore the clinical effects of negative pressure wound therapy (NPWT) combined with artificial dermis grafting and autologous skin grafting on repair of open joint wounds and/or wounds with exposed bone fracture.

METHODSEleven patients with open joint wounds and/or wounds with exposed bone fracture, hospitalized from November 2008 to November 2014, were enrolled in the study. According to the differences of the first stage treatment, all patients were divided into experimental group ( n = 6, including 4 patients of open joint wounds, 1 patient of wound with exposed bone fracture, and 1 patient of open joint wound with exposed bone fracture), and control group ( n 5, including 2 patients of open joint wounds, 2 patients of wounds with exposed bone fracture, and 1 patient of open joint wound with exposed bone fracture). After debridement, the wounds in both groups were grafted with punctured artificial dermis, while NPWT was only used over the artificial dermis of experiment group for 1 week. In the operation at sacsod stage, autologous split-thickness skin was grafted on the vascularized artificial dermis in both groups. Results In 5 patients of open joint wounds in experimental group, the artificial dermis was vascularized well, autologous skin grafts survived, and wounds were healed. In 3 patients of open joint wounds in control group, the artificial dermis grafting all failed due to local infection, and then these wounds were repaired with local tissue flap grafting. Artificial dermis in 3 patients of wounds with exposed bone fracture in both groups was vascularized well after grafting, and the wounds were healed after autologous skin grafting, whether or not NPWT was used.

CONCLUSIONSNPWT combined with artificial dermis grafting and autolognus skin grafting can be used for repairing open joint wounds and/or wounds with exposed bone fracture.

Objective To explore the effect of Eight-Section Brocadeon improving extrapulmonary performance and lung function in elderly stable chronic obstructive pulmonary disease (COPD) patients. Methods A total of 120 elderly stable COPD patients were divided into experimental group and control group by random digits table method with 60 cases each. The experimental group received Eight-Section Brocade and the control group took a walk both based on the routine health education. The World Health Organization Quality of Life (WHOQOL)-BREF, 6 min walking test and lung function were conducted before and after intervention 12, 24 and 36 weeks. Results After intervention, the score of each field of WHOQOL-BREF were higher than those before intervention, comparison of two groups of physiological fields Ftime=57.112, Fgroup=10.510, Finteractive=13.653, all P<0.01; psychological field Ftime=240.209, Fgroup=6.201, Finteractive=6.902, all P<0.05;field of social relations Ftime=34.957, Fgroup=7.265, Finteractive=11.554, all P<0.01; environmentfield Ftime=66.431, Fgroup=8.197, Finteractive=18.413, all P<0.01, and there were significant differences in time, groups and interactive. Comparison of two groups of the result of 6 min walking test after intervention, Ftime=327.697, Fgroup=37.181, Finteractive=61.420, all P<0.01. Comparison of two groups of the result of lung function indexforced expiratory volume in one second, Fgroup=5.083, P<0.05, there was significant difference;after intervention the index of Forced expiratory volume in 1 second take up of the expected value, Fgroup=4.141, P<0.05, there was significant difference. Conclusions Eight-Section Brocade can effectively improve the elderly stable COPD patients with exercise endurance and quality of life, improve the extrapulmonary performance, delay the progressive decline of lung function.

As one of the chronic disease of respiratory system,chronic obstructive pulmonary disease contributes to a progressive decline of lung function,as well as the extra-pulmonary effects.Malnutrition,one of the extra-pulmonary effects,becoming the common problem for chronic obstructive pulmonary disease patients.It has severe harm to chronic obstructive pulmonary disease patients that need us to pay more attention to it.The choice of nutrition assessment tools has important significance for the correct results of nutrition status of the patients.

Objective:To investigate whether radiotherapy should be delivered before the application of immune checkpoint inhibitor PD-1 in patients with advanced non-small cell lung cancer (NSCLC) and evaluate the effect of previous radiotherapy on the efficacy and pulmonary toxicity of PD-1 inhibitor.Methods:Clinical data of patients with stage Ⅳ NSCLC who received immunotherapy in Henan Cancer Hospital from March 2015 to September 2019 were retrospectively analyzed. The baseline data of patients, the status of radiotherapy and immunotherapy and the pulmonary toxicity were collected. According to whether radiotherapy was given before PD-1 inhibitor application, all patients were divided into the previous radiotherapy and non-radiotherapy groups. Survival analysis was performed by Kaplan- Meier method. Results:A total of 90 patients were enrolled including 39 cases in the previous radiotherapy group and 51 cases in the non-radiotherapy group. The median follow-up time was 22.9 months. The median progression-free survival (mPFS) in the previous radiotherapy group was 7.5 months (95% CI 5.4-9.5 months), significantly longer compared with 4.1 months (95% CI 3.1-5.1 months) in the non-radiotherapy group ( P=0.003). The median overall survival (mOS) significantly differed between two groups[15.2 months (95% CI 12.3-18.1 months) vs. 9.3 months (95% CI 6.1-12.5 months)]( P=0.040). The incidence of pulmonary toxicity showed no significant difference between two groups ( P=0.154). Conclusions:Patients with stage Ⅳ NSCLC patients in the previous radiotherapy group obtain significantly better mPFS and mOS and similar pulmonary toxicity compared with their counterparts in the non-radiotherapy group. Nevertheless, the findings remain to be validated by subsequent investigations with larger sample size.

Objective: To investigate the prevalence and influencing factors of abnormal ankle-branchial index（ABI）among community diabetic patients in Liangxi District of Wuxi. Methods: From April to October 2018,the community patients with type 2 diabetes mellitus（T2DM）were selected from 12 streets in Liangxi District by convenient sampling method. The general information,body mass index（BMI）,fasting blood glucose and ABI of the patients were collected by questionnaire survey,physical examination and laboratory test. The influencing factors for ABI abnormality were analyzed by multinomial logistic regression models. Results : A total of 2 235 patients with T2DM were investigated,with an average age of（67.74±7.85）years old and an average course of disease of（10.25±7.38）years. There were 210 cases（9.40%）of low ABI,1 972 cases（88.23%）of normal ABI,and 53 cases（2.37%）of high ABI. The results of multinomial logistic regression analysis showed that systolic blood pressure（OR=1.021,95%CI：1.013-1.029）,age（OR=1.081,95%CI：1.059-1.105）,course of disease（OR=1.023,95%CI：1.004-1.041）and regular exercise（OR=0.499,95%CI：0.366-0.681）were influencing factors for low ABI;BMI（OR=1.120,95%CI：1.034-1.213）was a risk factor for high ABI. Conclusions The prevalence of abnormal ABI is high among community patients with T2DM in Liangxi District. Systolic blood pressure,age,course of disease,BMI and regular exercise are the influencing factors for ABI abnormality.

OBJECTIVETo discuss whether asiaticosides could effectively reduce the endothelial cell damage as a biochemical modulator, so as to further inhibit the post-stenting intima-media membrane hyperplasia.

METHODHuman aortic smooth muscle cells and aortic fibroblasts were selected and divided into the blank group, the rapamycin group and the asiaticoside group and the rapamycin and asiaticoside group. The expressions of muscle cells and fibroblasts TGF-beta1, Smad7 and I-collagen gene were determined by RT-PCR. The expression quantity of I-collagen protein was assayed by ELISA. The coefficient of drug interaction (CDI) between rapamycin and asiaticoside was calculated. Additionally, 16 Chinese mini-swines were randomly divided into group A and group B. One sirolimus drug-eluting stent of the same type was implanted after the high-pressure pre-expansion of anterior descending artery balloon. After the operation, the group A was intravenously injected with normal saline 30 mL x d(-1). Whereas the group B was intravenously injected with asiaticoside 30 mg x kg(-1) x d(-1)(diluted to 30 mL). The expressions of plasma vWF of the two groups were measured at the 7th and 14th days after the operation. At the 28th day after the operation, tissues of the stented vessel segments were sliced and stained to calculate the vessel area, inner stent area, lumen area and neointima area

RESULTCompared with the control group, the combination group showed significant up-regulation in smooth muscle cells and fibroblast Smad7 gene, down-regulation in TGF-beta, and obvious inhibition of I-collagen gene expression (P < 0.01). As for smooth muscle cells, there was no difference in the expression of I-collagen between the combination group and the rapamycin group, with CDI at 0. 83. As for fibroblasts, there was a significant difference in the expression of I-collagen between the combination group and the rapamycin group (P < 0.05), with CDI at 0.77. Plasma vWF of the group B was significantly lower than that of the group A (P < 0.05) at the 7th and 14th days after the operation. At the 28th day after the operation, no difference was observed in vessel area and stent area between the two groups. However, the lumen area in the group B was significantly larger than that of the group A(P < 0.05), and the neointima area of the group B was significantly smaller than that of the group A (P < 0.05).

CONCLUSIONAs an effective biochemical modulator for rapamycin, asiaticosides could inhibit TGF-beta expression, significantly decrease the synthesis and secretion of extracellular matrix, further inhibit the post-stenting intima-media membrane hyperplasia and reduce the endothelial cell damage by effectively up-regulate the expression of Smad7 protein.
