Chinese Journal of Rehabilitation Theory and Practice 2017;23(1):14-18
Objective To observe the effect of electroacupuncture on hand dysfunction after stroke. Methods Forty hemiplegic patients after stroke were selected from a multi-center large-scale trail, belonged to rehabilitation group (n=20) and electroacupuncture group (n=20), who accepted routine rehabilitation and additional electroacupuncture, respectively, for six weeks. They were assessed with Brunnstrom Grade, Fugl-Meyer Assessment (FMA), Wolf Motor Function Test (WMFT) and modified Barthel index (MBI) before treatment, two, four and six weeks during treatment, and twelve weeks after treatment. Results There were differences between two groups in scores of FMA, WMFT and total time to complete WMFT twelve weeks after treatment (t>1.900, P<0.05). There was no difference between two groups in scores of MBI and Brunnstrom Grade (t=0.532, Z<1.79, P>0.05), but electroacupuncture group seemed to improve more. Conclusion Elec-troacupuncture may improve the muscle strength for patients in flaccid paralysis, and promote the recovery of hand function for patients af-ter stroke.

Objective To observe the effects of LPS and PMA on proliferation of human len epithelial( HLE )cells and expression of epidermal growth factor receptor(EGFR) in HLE cells.Methods The expressions of EGFR protein of HLE cells from felus,adult lens age-related cataract and cultured HLE cells were detected by immunohistochemical staining.The expression of EGFR mRNA was detected by RT-PCR.The effects of LPS (0.5,1.0,2.0 mg?L-1 ) and PMA(25,50,100 nmol?L-1 )on proliferation of HLE cells were detected by MTT colorimetry method,and the EGFR mRNA expression in HLE cells was determined by RT-PCR. Results The expressions of EGFR protein and mRNA were positive in HLE cells from felus,adult lens age-related cataract and cultured HLE cells.The proliferation rates of HLE cells treated with 0.5,1.0,2.0 mg?L-1 LPS were (3.21?0.42)%,(12.25?1.34)% and (36.67?3.65)%,respectively.The proliferation rate of HLE cells in 2.0 mg?L-1 LPS group was higher than those in 0.5 and 1.0 mg?L-1 LPS groups(F=7.709,P0.05).PMA(25,50,100 nmol?L-1 )could not effect the expression of EGFR mRNA in HLE cells .Conclusion Inflammation stimulant factor such as LPS can promote the proliferation of HLE cells by increasing the expression of EGFR and result in occurrence of posterior capsular opacifition(PCO).

Objective To investigate nutrition and health behavior situation and mental situation on puerperal women of Chongqing,in order to provide scientific basis on their pertinent health education. Methods 424 puerperal women were chosen to take health care questionnaire and anxiety self-test table,and investigated by interviewers who had been through professional training,and then doing statistical analysis. Results Women in puerperal in Chongqing had some unreasonable nutrition and health knowledge and mental situation,diet behavior inhibition and so on. Among them,only 49.51% needed calcium supplementation,only 79.37% held that they could have fruit during confinement in childbirth,as high as 66.02% went out after confinement,only 33.49% washed during puerperal,20.39% had over light anxiety. Conclusion It is necessary to reinforce health education and puerperal health guide to puerperal women in Chongqing to improve nutrition and health level and mental situation of puerperal women.

The purpose of this study was to study the effect of three different transfection reagents (Lipofectamine™ LTX & PLUS™, Lipofectamine 2000 and Nano-PAMAM-D) and three different testicular injection methods (rete testicular injection, seminiferous tubules injection and testicular interstitial injection) on the efficiency of production transgenic mice. After the mixtures of plasmid DNA (pEFP-C1) and transfection reagent were injected with different testicular injection methods, the sperm density, vitality, positive sperm rates and PCR positive transgenic mice rate were examined 30 days after injection. The results showed that the damage degree from slight to serious of three transfection reagents was Lipofectamine™ LTX & PLUS™, Lipofectamine 2000, and PAMAM-D. The sperm positive rates with green fluorescence of these three groups were 35.65%±0.69%, 12.86%±0.35% and 10.04%±0.20%, respectively. The PCR positive rates of transgenic newborn mice were 29.17%, 13.70% and 5.88%, respectively. Among the groups of different testicular injection methods, the damage degree from slight to serious was rete testicular injection, seminiferous tubules injection, and testicular interstitial injection, whereas the sperm positive rates with green fluorescence were 35.13%, 15.13%, and 0%, respectively. The PCR positive rates of transgenic newborn mice among different testicular injection groups were 33.3%, 12.5%, and 0.0%. The combination of rete testicular injection and Lipofectamine™ LTX & PLUS™ had the lowest toxicity and highest transgenic efficiency in the production of transgenic mice.

AIM: To investigate the role of reactive oxygen species ( ROS)-mediated mitochondrial oxidative injury in isonicotinyl hydrazide ( INH)-induced DNA damage and the protective effect of quercetin on L-02 cells.ME-THODS:The injury model of hepatocyte L-02cells in vitro induced by INH was established .The cells were divided into control group, INH group, low-dose quercetin group and high-dose quercetin group.The DNA damage of L-02 cells was evaluated by the comet test .The mitochondrion was prepared , and the level of mitochondrial ROS and the value of mitochondrial membrane potential (ΔΨm ) were detected by fluorescent probes DCFH-DA and rhodamine 123.The content of MDA was measured by TBA method .The activity of SOD was assessed with the xanthine oxidase method .The protein expression of Bcl-2 and Bax was determined by Western blotting , and the value of Bax/Bcl-2 was calculated .RESULTS:INH induced obvious DNA damage , increased the level of mitochondrial ROS , the content of MDA and the value of Bax/Bcl-2, and markedly reduced the value of ΔΨm and the activity of SOD in the L-02 cells.Quercetin attenuated DNA dam-age, reduced the level of mitochondrial ROS , elevated the value of ΔΨm , declined the content of MDA , increased the ac-tivity of SOD and decreased the value of Bax/Bcl-2 in the L-02 cells.CONCLUSION:INH induces DNA damage in L-02 cells by generation of mitochondrial oxidative stress .Quercetin has a protective effect on L-02 cells to attenuate the INH-in-duced DNA damage by inhibiting ROS-mediated mitochondrial oxidative damage .

BACKGROUND:Which an ideal method to treat type Rockwood Ⅲ acromioclavicular joint dislocation is,traditional or surgical therapy,is still controversial.OBJECTIVE:To investigate the clinical effect of clavicular hook plate implantation on type Rockwood Ⅲ acromioclayicular joint dislocation.METHODS:A total of 56 patients with type Rockwood Ⅲ acromioclavicular joint dislocation were selected from Department of Orthopaedics of Yiling Hospital between December 2005 and June 2008.There were 42 males and 14 females,aged 16-65 years and mean age of 32 years.All patients were treated with clavicular hook plate implantation.Indicators including visual analogue scale (VAS),the United States shoulder and elbow surgeon score (ASES),and Constant and Murley scoring system were tested pre-operatively,one year postoperatively,before internal fixation,and 3 months after internal fixation;additionally,functional changes of the shoulder joint and complications were analyzed before and after clavicular hook plate implantation.RESULTS AND CONCLUSION:The surgery and following-up were successfully achieved in 56 cases.The following-up lasted for 15-30 months,with the mean time of 20 months.The internal fixation was taken out at about 1 year after implantation.Coracoclavicular ligament was repaired in 32 cases but not in the 24 cases.Two patients with acromioclavicular joint dislocation recurrence were excluded,and coracoclavicular ligament therapy was not performed.Shoulder pain,foreign body sensation,and internal fixation failure occurred in two cases.One year after operation,VAS was decreased compared with that before operation,but ASES and Constant and Murley score were significantly increased (P<0.01).At three months after internal fixation,VAS was decreased compared with that at 1 year after operation,but ASES and Constant and Murley score were increased (P<0.05).The results demonstrated that clavicular hook plate implantation for treating type Rockwood Ⅲ acromioclavicular joint dislocation is simple and less invasive,thus it is an ideal internal fixation.
