BACKGROUND:There is little attention focused on the effect of isokinetic testing about the variation of angular velocity on pain and muscle strength in the evaluation of curative effect of McConnel taping. OBJECTIVE: To evaluate the changes of quadriceps muscle strength and perceived pain levels in patients with patelofemoral pain syndrome before and after corrective McConnel taping in isokinetic testing. METHODS:A total of 34 patients with patelofemoral pain syndrome were evaluated in isokinetic testing for concentric contraction muscular strength, including the maximum torque, the total work, and the average work in 60 (°)/s and 180 (°)/s angular velocity, before and after the interventions of McConnel taping. The visual analogue scale scores were recorded. RESULTS AND CONCLUSION: The visual analogue scale scores were slightly decreased in angular velocity of 60 (°)/s after obturation when compared to before obturation (P > 0.05), while the scores were significantly decreased in angular velocity of 180 (°)/s (P < 0.05). The maximum torque, the total work, and the average work were slightly increased after obturation, but showed no significant difference in angular velocity of 60 (°)/s (P > 0.05), while significantly increased in 180 (°)/s angular velocity (P < 0.05). McConnel taping significantly improves the curative effect in patients with patelofemoral pain syndrome under low load joint movement.

Objective To investigate the effects of early physiotherapy in combination with atorvastatin on the levels of serum brain-derived neurotrophic factor (BDNF) and neurological function in patients with acute ischemic stroke.Methods Fifty patients with acute ischemic stroke were randomly divided into either an atorvastatin group (monotherapy group,n =25) or a early physiotherapy + atorvastatin group (combination treatment group,n =25).All patients received the prescribed drugs according to the diagnosis and treatment guidelines for ischemic stroke.The monotherapy group added atorvastatin calcium (20 mg,1 tablet every night orally).On the basis of the monotherapy group,the combination treatment group also conducted early physical therapy.At 2 and 6 weeks before and after treatment,a double-antboody sandwich enzyme-linked immunosorbent assay was used to detect the serum BDNF levels.The National Institutes of Health Stroke Scale (NIHSS) was used to evaluate the degree of neurological deficit.Barthel index (BI) was used to evaluate the activities of daily living.The modified Rankin scale (mRS) was used to assess the degree of disability.Results There was no significant difference in demographics and baseline data between the monotherapy group and the combination treatment group.The scores of NIHSS,BI,and mRS in both groups after treatment were significantly better than those before treatment (all P < 0.001).There were no difference in the scores of NIHSS,BI and mRS at 2 weeks before and after treatment,but at 6 weeks after treatment,the scores of NIHSS (2.40 ± 1.38 vs.3.36 ± 1.73; P =0.035) and mRS (1.40 ± 0.87 vs.1.96 ±0.94; P =0.047) of the combination treatment group were significantly lower than those of the monotherapy group,and the BI scores (92.60 ±7.50 vs.85.20 ± 11.68; P=0.011) were significantly higher than those of the monotherapy group.After treatment,the serum BDNF levels were increased significantly in both groups.There were significant differences among all the time points (all P<0.001).At 2 weeks after treatment,the serum BDNF levels (3.07 ±0.93 ng/ml vs.2.45 ±0.76 ng/ml; t =2.559,P =0.014) and at 6 weeks after treatment,those (2.90 ± 0.93 ng/ml vs.2.31 ± 0.77 ng/ml; t =2.433,P =0.019) in the combination treatment group were significantly higher than those in the monotherapy group.Spearman correlation analysis showed that the serum BDNF levels were significantly negatively correlated with the scores of NIHSS (r =-0.738,P < 0.001) and mRS (r =-0.654,P < 0.001),but they were significantly positively correlated with the BI scores (r =0.716,P < 0.001).No serious adverse reaction occurred in both groups.Conclusions Early physiotherapy in combination with atorvastatin for the treatment of acute ischemic stroke can more effectively promote the recovery of neurological function,and its mechanism may be associated with the increased serum BDNF levels.

Objective To investigate the anticancer effect of oxymatrine on cervical cancer cell line (HeLa). Methods MTT assay was used to detect the anti-proliferative effect of oxymatrine.Transwell chamber was used to detect the anti-metastatic effect of oxymatrine.Real-time PCR was used to detect the mRNA levels of MMP-2 and MMP-9.Western blot was used to detect the protein levels of MMP-2,MMP-9,AKT,p-AKT and GADPH. Results We found that application of oxymatrine significantly inhibited the growth of HeLa cells at the concentration above 0.8 mg/mL.We also found that oxymatrine (0.1,0.2 and 0.4 mg/mL)inhibited the invasion of HeLa cells under cytotoxic dose,which was (77.07±20.43)%,(53.95±18.17)% and (20.35±11.20)% of cells that migrated through the matrigel when compared with those of non-oxymatrine treatment group (P<0 .0 5 ). Further research found that oxymatrine (0.1,0.2 and 0.4 mg/mL)could reduce the expression of MMP-2 at the mRNA level,i.e.(82.76±8.71)%,(39.51±12.79)% and (21.53±5.38)% of the expression level when compared with that of non-oxymatrine treatment group (P<0 .0 5 ).The protein expression level of MMP-2 in 0 .4 mg/mL group was (64.69 ±16.52)% of non-oxymatrine treatment group (P<0.05).The phosphorylation level of AKT in 0.4 mg/mL group was (41.27±7.13)% of non-oxymatrine treatment group (P<0.05).Conclusion Oxymatrine can inhibit the invasion of HeLa cells by reducing the expression of MMP-2 via inhibiting the activity of AKT signal pathway.All together,our findings bring new insights into the mechanism of the anticancer effects induced by oxymatrine treatment.

The concept of humanistic education is based on the concern of human beings and their abilities of development. Thus,it is an educational concept to optimize the teaching modules.It stresses the point that education must regard the develop- ment of human beings as the main line and human beings should be emphasized in education from the very beginning to the end. Case-Teaching Method which takes the students as the main part fully manifests the concept of humanistic education,in which all teaching activities and the processes closely revolve the students in order to train them to carry on their studies and to solve the problems independently.
9. Enlightenments of Padma Circosan Capsules to registration of compound Chinese materia medica products in European Union
Chinese Traditional and Herbal Drugs 2019;50(18):4511-4516
The European Union (EU) law 2004/24/EC has simplified the registration of traditional herbal medicines, which makes it possible for Chinese materia medica (CMM) to enter the EU as medicines. To register CMM products in the EU is an important way to realize the internationalization of CMM. Compound combination is the main clinical application form of CMM under the guidance of CMM syndrome differentiation. How to register compound CMM products in EU has become one of the important realistic topics for the internationalization of CMM. A total of 630 applications for traditional herbal medicinal products have been approved by the EU member states since the implementation of the Directive 2004/24/EC in 2005. Among these products, Padma Circosan Capsules was the only approved one originated from CMM area. The course of this product lead us with the enlightenment for the compound CMM products in three aspects: The literatures and evidence about safety and traditional use of "related product" are the core components in the non-clinical and clinical application materials for the registration of both combination and mono-component CMM products; The traditional application and safety evidence of "related products" as well as the relevant materials and data of EU monograph constitute the important content for the registration and approval of compound CMM products in EU member states; Applicants should pay more attention to the study of genotoxicity and the systematic collection of post-marketing pharmacovigilance data.
