4.Experimental study of Renshen-heche Tablets on tonifying and warming Shen-Yang
Chinese Traditional Patent Medicine 1992;0(11):-
Objective: To study the effect of Resen heche tablets (RSHC) on tonyfing and warming Shen Yang. Methods: The mice model of Shen Yang deficiency was established by injecting hydrocortisone. The body weight, autonomic activity and swimming time in ice water in model mice were observed. The level of superoxide dismutase (SOD) in red cell and lipid peroxide (LPO) in plasma of aged rats were analyzed. The effect on anti stress in mice was examined. Results: RSHC had the remarkable effect to improve body weight and autonomic activity and to prolong swimming time in ice water in model mice, and to increase SOD activity and reduce LPO in blood of aged rats, and to elevate the ability of anti fatigue and anoxic tolerance in mice. Conclusion: RSHC drug has the effect on tonifying and warming Shen Yang; can promote growth, enhance organism activity, elevate the adaptation to circumstances and protect injury from free radicals.

6.Expression of connexin 43 in ovarian cancer and its relationship with chemoresistance
Chinese Journal of Obstetrics and Gynecology 2009;44(1):50-55
Objective To examine the expression of protein kinase C (PKC), connexin43(Cx43) and non-phosphorylated Cx43 in ovarian cancer, and discuss the role of phosphorylated of Cx43 in chemoresistance in ovarian cancer. Methods We examined the expression of Cx43, non-phosphorylated Cx43 and PKC in ovarian cancer tissue by immunohistochemistry, and compared their expression in chemosensitivity group and ehemoresistance group. Cisplatin resistant ovarian cancer cell line SKOV3/DDP cells were treated by staurosporine (a kind of PKC inhibitors). Then expression of Cx43, non-phosphorylated Cx43 and PKC were tested. Meanwhile, we tested chemosensitivity of SKOV3/DDP cells by ATP bioluminescence tumor chemosensifivity assay (ATP-TCA). Results (1) Immunohistochemically,the rates of positive expression of Cx43 and non-phospharylated Cx43 were 54%, 14% respectively in the chemoresistance group, which were 83%, 59% in the chemosensitivity group respectively (P<0.05). The rate of positive expression of PKC in 28 chemoresistance ovarian cancer cases (64%) was higher than that in 29 chemosensitivity cases (31% ,P<0.05). Both of them were significantly lower in ehemoresistanee group than in chemosensitivity group (P<0.05). In addition, the expression of PKC was negatively correlated with the expression of Cx43 and non-phosphorylated Cx43. The correlation coefficients were -0. 626 and -0. 714, respectively (P<0.05). (2) Immunohistochemically, PKC was down regulated, and Cx43 and non-phosphorylated Cx43 were up regulated in SKOV3/DDP cells after staurosporine treatment. The longer the staurosporine worked, the more expression of Cx43 was. (3) By ATP-TCA, SKOV3/DDP cells were resistant to paclitaxel and cisplatin. The tumor growth inhibition was higher in the group of paclitaxel or cisplatin combined staurosporine than in the group of paclitaxel or cisplatin alone. The sensitivity was intermediate in the group combined with low concentration staurosporine (1×10-8 moL/L), and the sensitivity was high in the group combined with high concentration staurosporine (1×10-7 mol/L). Conclusions Phosphorylation of Cx43 caused by PKC leads to decrease in the expression of Cx43. This effect makes ovarian cancer cells less chemosensitive. Phosphorylation of Cx43 caused by PKC can be inhibited by staurosporine.
7.Current status of mechanical thrombectomy for acute ischemic stroke
International Journal of Cerebrovascular Diseases 2016;24(1):63-67
Before irreversible neuronal damage occurs, quickly and securely recanalize vessels and restore blood flow to save the ischemic penumbra tissue are the main therapeutic target for acute ischemic stroke (AIS). Currently, the method for recanalization in early AIS is intravenous thrombolysis, how ever, the effect of intravenous thrombolysis is often not satisfactory because of the reasons, such as its short treatment time w indow , low vascular recanalization rate, and high incidence of bleeding complications. In recent years, w ith the research and development of mechanical thrombectomy device and the development of interventional technology, the therapeutic time w indow of AIS has been significantly prolonged, the vascular recanalization rate has increased significantly, the clinical outcome has improved significantly, and the treatment of mechanical thrombectomy has show n good application prospects.

Chinese Journal of Practical Nursing 2015;31(6):450-453
Objective The study aimed to explore the reliability and validity of the Chinese version of the Nottingham Assessment of Functional Footcare (NAFF) in investigating the footcare behavior's level in patients with high risk of diabetic foot.Methods According to Bradley's principle,NAFF was converted into the Chinese version scale,then it was applied to 211 cases of patients with high risk of type 2 diabetic foot,and the reliability and validity of foot care be-havior scores were analyzed.Results In the Chinese version scale,the Cronbach's alpha coefficient was 0.77,test-retest reliability was 0.74.Content validity,ICVI was 0.80 to 1.00,S-CVI/Ave was 0.96,and the adjusted value of kappa was 0.75 to 1.00.Conclusions The questionnaire has been tested to have good reliability and validity.The NAFF possesses certain value in the clinical application and could be suitable for Chinese patients with high risk of type 2 diabetic foot.

International Journal of Pediatrics 2015;42(5):587-589
Objective To examine miRNA-31 expression in serum of children with airway allergic disease (asthma and allergic rhinitis) and determine the correlation with CD44.Methods The expression of miR-NA-31 and CD44 in serum of 26 children with acute asthma and allergic rhinitis and non-acute phase and 36 normal control children were determined by real-time reverse transcriptase polymerase chain reaction.Results The miRNA-31 was significantly overexpressed in serum of children with acute asthma and allergic rhinitis compared with non-acute phase and normal control children and significantly correlated with CD44.Conclusion The correlation between miRNA-31 and CD44, the aberrant expression of miRNA-31 may account for the occurrence and development of airway allergic diseases.
10.Discussion on ways of improving the ability of doctor-patient communication of paediatric sur-geon in standardized training
Chinese Journal of Medical Education Research 2015;(3):322-324
The doctor-patient relationship is always the focus in the society. The relationship seems more complex and sensitive in the pediatric surgical ward because its patients are kids. However, the pediatric surgical residents' ability of doctor-patient communication is lack of systemic and norma-tive training, which is not good for the mutual understanding between doctors and patients. This study explores how to enhance the residents' doctor-patient communication skills from the perspective of awareness, professional knowledge and some specific skills. In the meantime, it discusses the need to train the teachers and set up a regular examination-assessment system.
