2.Advances in mechano-biological behavior of peridontal ligament during orthodontic tooth movement
International Journal of Biomedical Engineering 2013;36(6):367-370,380
Orthodontic tooth movement (OTM) is a very complicate mechano-biological procedure which is accomplished by the remodeling of periodontal tissues via orthodontic force.As the connective tissue between alveolar bone and cementum,periodontal ligament plays a vital role in the response and conduction of orthodontic force.The susceptible response of periodontal ligament to orthodontic force during OTM is a critical factor on inducing and modulating periodontal tissue restitution.This article reviews the concrete role of periodontal ligament and its mechano-biological behavior during OTM,discusses its mechanical response and biological mechanism respectively on histological,cellular and moleucular levels.

4.Study on application of B-type ultrasound guided modified Seldinger technique for PICC in patients with lung cancer
International Journal of Laboratory Medicine 2017;38(16):2188-2189,2192
Objective To investigate the clinical effect of adopting B-type ultrasound guided peripherally inserted central catheter (PICC) in the patients with lung cancer.Methods Two hundreds and ninety-five cases of lung cancer undergoing PICC in our hospital from January 2011 to May 2016 were selected as the research subjects and divided into the observation group (151 cases) and control group (144 cases) according to the PICC methods.PICC in the observation group adopted the B-type guided modified Seldinger technique,while the control group adopted the conventional method.The venous thrombus occurrence situation in the two groups was comparatively analyzed.Results (1) The platelet count (PLT),plasma D dimer (D-D) and thromboxane B2 (TXB2),endothelin (ET),6-keto-prostaglandin F1 alpha (6-keto-PGF1α) before PICC had no signigicant difference between the two groups (P>0.05).PLT,D-D,TXB2 and ET at 12,24 h after PICC in the observation group and control group were gradually increased,while plasma 6-keto-PGF1α was gradually decreased,the intra-group difference among different time points had statistical significant (P<0.05).PLT and plasma D-D,TXB2 and ET in the observation group were significantly lower than those in the control group,while keto-PGF1α was significantly higher than that in the control group,the difference between the two groups was statistically significant(P<0.05).(2)The incidence rate of venous thrombosis in the observation group was significantly lower than that in the control group,the difference was statistically significant between the two groups (P<0.05).Conclusion Adopting B-type ultrasound guided modified Seldinger technique for PICC in the patients with lung cancer has much lower incidence rate of venous thrombosis.

6.Expression and location of IL-2/IFN-? fusion protein in colorectal tumor cell lines
Chinese Journal of Practical Internal Medicine 2006;0(18):-
Objective If IL-2 and IFN-? are united,perhaps we may see a more significant antitumor effect.A fusion gene of IL-2 and IFN-? was designed and constructed by DNA engineering.Methods CEA promotor、IL-2cDNA and IFN-?cDNA were obtained by PCR and RT-PCR.SDS-PAGE was used to examine the results;pcDNA-IL-2、pcDNA-IFN-?、pCEA-IL-2/ IFN-?、pEGFP-IL-2/ IFN-? were transfected to CEA high expression cell line(Lovo)by use of liposome.The fusion protein expression was examined by fluorescence microscope and Western blotting.Results IL-2/ IFN-? fusion gene can be expressed in tumor cells.Its expression is more obvious in CEA high expressed cells(Lovo),and can be located in cell plasma.Conclusion The fusion gene can be expressed in plasma of CEA high expressed cell lines.It may have a new anti-tumor effects.

8.Application of quality control circle in increasing face mask wearing rate of hospitalized pulmonary tuberculosis patients
Chinese Journal of Infection Control 2015;(5):332-335
Objective To evaluate application effectiveness of quality control circle (QCC)in increasing the face mask wearing rate of hospitalized pulmonary tuberculosis (TB)patients.Methods Nine nurses in department of tu-berculosis formed a ‘circle’,the theme of ‘improving the face mask wearing rate of hospitalized pulmonary TB pa-tients’was established,rectification measures were formulated and implemented,face mask wearing rates of pa-tients before and after implementing QCC activities were analyzed statistically.Results The face mask wearing rate of hospitalized pulmonary TB patients after implementing QCC activities was higher than that before implementing QCC activities (87.50% [147/168]vs 65.54%[116/177],P <0.05).The abilities of every ‘circle member’have been improved in the following aspects:problem-solving skills,sense of responsibility,communication skills,self-confidence,team working,enthusiasm,quality-control techniques,and cooperation abilities,the total average score increased from 23.78 before implementing QCC to 33.78 after implementing QCC.Conclusion QCC activities can not only improve the face mask wearing rate of hospitalized pulmonary TB patients,but also enhance circle mem-bers’quality-control skills and team spirit.
9.Activator protein-1 mRNA expression, cell proliferation and collagen synthesis induced by tumor necrosis factor-alpha in cardiac fibroblasts from rats and the effect of Qiangxin Decoction
Journal of Integrative Medicine 2008;6(9):946-51
OBJECTIVE: To investigate the function of activator protein-1 (AP-1) in proliferation and collagen synthesis of cardiac fibroblasts (CFs) in neonatal rats induced by tumor necrosis factor-alpha (TNF-alpha), and to explore the mechanism of Qiangxin Decoction (QXD), a compound traditional Chinese herbal medicine, in reversing cardiac fibrosis. METHODS: CFs derived from neonatal rats were cultured with enzymatic dissociation, and fibrosis of the CFs was induced by TNF-alpha. The CFs were divided into normal control group, untreated group, 5% QXD-containing serum group, 10% QXD-containing serum group and 20% QXD-containing serum group. After 24-hour culture of QXD-containing serum, AP-1 mRNA was detected by real-time fluorescent quantitative polymerase chain reaction; proliferation and collagen synthesis of CFs were assayed by thiazolyl blue assay (MTT) and measured by hydroxyproline respectively, in order to determine the effect of different dosage decoction on the proliferation and collagen synthesis of CFs. RESULTS: After 24-hour stimulation of TNF-alpha in CFs, compared with those in normal control group, the expression of AP-1 mRNA and cardiac fibroblast proliferation and collagen synthesis increased significantly (P<0.05). However, Qiangxin Decoction could reduce the expression of AP-1 mRNA and decreased the proliferation and collagen synthesis of CFs significantly (P<0.05). CONCLUSION: Qiangxin Decoction can inhibit proliferation and collagen synthesis of CFs induced by TNF-alpha, and reverse cardiac fibrosis, which may be related to its down-regulation of the expression of AP-1.
10.A meta-analysis on the efficacy and safety of autologous drainage blood reinfusion in total knee arthroplasty
The Journal of Practical Medicine 2014;(10):1644-1647
Objective To assess the efficacy and safety of autologous drainage blood reinfusion in total knee arthroplasty(TKA). Methods Computers were used to search the Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, and VIP. The randomized controlled trials (RCTs) of autologous drainage blood reinfusion and vacuum suction without reinfusion after TKA were collected. And the results were analyzed by using the software RevMan5.1. Results Eight RCTs met the criteria for meta-analysis. Use of autologous drainage blood reinfusion significantly reduced the average amount of units of homologous blood transfusion, the length of hospital stay, and the number of patients requiring homologous blood transfusion. The rates of DVT formation and incision infection did not differ significantly between the two groups. Conclusions Autologous drainage blood reinfusion is a safe, effective procedure with less blood transfusion and medical cost. It can lower volume of allogeneic blood transfusion , shorten length of hospital stay, and avoid occurrence of complications.
