As the change of concept of health,the aim of medicine is not only to prolong life and improve the function of organs,but also to help patients to integrate to social life.Previous studies always pay much attention to clinical outcomes ineluding mortality,morbidity,long-term or short-term survival,but patients with liver cancer usually have long disease history and with background diseases such as liver cirrhosis.Traditional liver transplantation and liver resection ale both effective modalities for liver cancer,but liver resection has disadvantages of hish recurrence rate and repeated hepatic artery interventional therapy,and liver transplantation is high-cost.So the health economics and life quality of patients should not be ignored when comparing liver transplantation and liver resection.

AIM:To find a new way of treating premature beats(PB) to evaluate the efficacy and safety of Yi-(xinshu) Capsule(Radix et Rhizoma Ginseng,Radix et Rhizoma Salviae miltiorrhizae,Radix Ophiopogonis,Radix Astragali,etc.) METHODS:Randomized,controlled clinical study were conducted in 60 patients with atrial premature beats(APB),and 60 patients with premature ventricular beats(PVB).APB patients were randomly divided into two groups:Yixinshu Capsule plus Isoptin(study group,n=30) and Isoptin group(control group,n=30).PVB patients:Yixinshu Capsule plus Mexiletine(study group,n=30) and Mexiletine group(control group,n=30).Those patients were treated for four weeks.We used 24 h Holter to monitor the times of PB and myocardial ischemia in before and after treatment.RESULTS:In the study group and control group,the times of APB and PVB were decreased obviously after 4 weeks treatment(P

Objective To explore the therapeutic effect of low level laser irradiation (LLLI) on cerebral infraction combined with hypertension.Methods Two groups were divided, conventional treatment group and laser irradiation combined with conventional treatment group.LLLI (650 nm, 20 mW, 20 min, twice a day, two weeks therapy) was used by extravascular way in addition to conventional treatment, while control group employed conventional treatment only.Whole blood viscosity, plasma blood pressure, lipid and neurological function were assessed by comparing the index of the two groups.Results Whole blood viscosity, plasma viscosity, whole blood high shear reductive viscosity, hematokit (HTC), erythrocyte deformation index, erythrocyte rigidity index, fibrinogen and blood lipid level of both groups decreased and the decrease of the testing group was more significant than that of control group (P＜0.05 or P＜0.01).Neurological deficit score an blood pressure of both groups showed significant decrease (P＜0.05), and the decrease in blood pressure of testing group was significant than that of the control group (P＜0.05 or P＜0.01).Conclusions 650 nm extravascular LLLI may be effective in treatment of cerebral infraction combined with hypertension, and has a good application prospect.

Objective To observe clinical efficacy of warm-promotion needling for the treatment of cold coagulation and blood stasis of primary dysmenorrhea.Methods Totally 120 patients with cold coagulation and blood stasis of primary dysmenorrhea were randomly divided into warm-promotion needling group (60 cases) and control group (60 cases). Warm-promotion needling group was treated with warm-promotion needling at Guanyuan (RN4), Sanyinjiao (SP6), Shiqizhui (EX-B8), and Diji (SP8), and cooperated with Ciliao (BL32), Hegu (LI4), and Taichong (LR3). Control group took same acupoints and applied uniform reforcing-reducing method. The two groups began treatment 5-7 d before menstruation, 1 times a day, for 7 times. The treatment was given 3 menstrual cycles. The visual analogue scale (VAS) and COX menstrual symptom scale (CMSS) were used to observe the pain degree at the end of 1, 2, 3 menstrual cycles. The clinical efficacy was evaluated 3 months after treatment.Results The scores of VAS and CMSS was obviously reduced in the two groups after the treatment compared with those before treatment (P<0.01). The synperiodic scores of VAS and CMSS in warm-promotion needling group was obviously lower than those in the control group (P<0.05). The total effective rate of warm-promotion needling group was 96.67% (58/60), and the control group was 73.33% (44/60), the difference was significant (P<0.05).Conclusion Warm- promotion needling can obviously relieve dysmenorrhea symptoms and shorten the time of pain of patients with cold coagulation and blood stasis of primary dysmenorrhea, which has affirmative clinical efficacy.

Objective: To give the living-donor and recipient medical evaluation and moral evaluation pretransplant by Academic and Ethics Committee for Organ Transplantation (AECOT), ensure the transplantation proceed smoothly and the feasibility for moral principles. Methods:AECOT was formed and gave the living-donor and recipient medical evaluation, additional moral evaluation to their family, evaluated the possibility for transplantation, ensured the long-dated safety for living-donor and recognition for ethics, ensured the transplantation proceed successfully. Results: 18 cases were evaluated by AECOT, two cases had the operation refused because of the II-diabetes for one living-donor and the other living-donor refused evaluation, one case had the operation delaied because of the overweight for the living-donor. The rest 15 cases were accepted operation smoothly,both donor and recipient recovered well post transplant. Conclusion:Academic and Ethics Committee for Organ Transplantation(AECOT) is a essential agency for Living Donor Kidney Transplantation.

Objective To observe the therapeutic effect of segmental scleral buckling and vitrectomy with/without lensectomy on the retinopathy of prematurity (ROP) stage 4a,4b and 5.Methods One hundred and thirty-four ROP infants (181 eyes) diagnosed as stage 4a,4b and 5,and performed with segmental scleral buckling or vitreous with/without lensectomy were retrospectively analyzed.The operated 4a-,4b-and 5-stage eyes were 40,51 and 90 eyes.The operational method depended on the location and severity of fibrovascular membrane.Of 181 eyes,segmental scleral buckling was referred for 37 eyes which include 23 eyes with 4a stage and 14 eyes with 4b stage;vitrectomy was referred for 50 eyes which include 14 eyes with 4a stage,29 eyes with 4b stage and 7 eyes with 5 stage;vitrectomy with lensectomy was referred for 94 eyes which include 3 eyes with 4a stage,8 eyes with 4b stage and 83 eyes with 5 stage.The effect was classified as success,improved and failure.Failure includes lost eye.Follow-up for 4a,4b and 5 stage patients are 34,31 and 29 months respectively.Results Segmental scleral buckling was referred for 37 eyes,success in 23 eyes (62.16％),improved in 11 eyes (29.73 ％),failure in 3 eyes (8.11 ％).Vitrectomy was referred for 50 eyes,and success in 20 eyes (40.00％),improved in 22 eyes (44.00％),and failure in 8 eyes (16.00％).In the total of 94 eyes underwent vitrectomy with lensectomy,20 eyes was success (21.28％),improved in 17 eyes (18.08％),failure in 57 eyes (60.64％).In 40 stage 4a eyes,33 successes (82.50％),6 improved (15.00％) and 1 failure (2.50％).In 51 stage4b eyes,11 successes (21.57％),30 improved (58.82％) and 10 failures (19.61％).For 90 stage 5 eyes,14 successes (17.50％),19 improved (23.75％) and 57 failures (71.25％).The therapeutic effect of segmental scleral buckling for stage 4a was better than that for stage 5 (x2 =6.707,P=0.035).The difference of therapeutic effect of vitrectomy for different stage was significant (x2=21.010,P =0.000);stage 4a was the best;stage 4b was the second,stage 5 was the worst.The therapeutic effect of vitrectomy with lensectomy for stage 5 was worse than that for stage 4a and 4b (x2=16.066,P=0.003).Conclusion The surgery patterns of ROP was determined based on the disease severity,the surgery effects of stage 4a and 4b were better than stage 5,which had nothing to do with the surgical procedures.

AIM To study the protective effect of total glucosides of paeony(TGP)on complete cerebral ischemia reporfusion injury and its mechanism of action.METHODS A complete cerebral ischemia[FQ(10。46,X-WZ]- reperfusion model of rats was induced by clipping three arteries. The changes in eye colour, SOD activity, MDA contents and histopathological characteristics were observed. RESULTS TGP (TGP 10、20、40 mg?kg -1 ) markedly reduced the change of eye colour; TGP(20 mg?kg -1 ) obviously elevated SOD activity decreased and inhibited the MDA of increased contents of cerebral cortex, hippocampus and corpus striatum of cerebral ischemia reperfusion in rats; TGP(20 mg?kg -1 )possessed protective effects on the histopathological changes of ischemia cerebral tissues in rats. CONCLUSION TGP possessed obvious protective effects on the cerebral ischemia reperfusion injury, suggesting that the protective action of TGP is relative to anti-oxidative action.-

Objective To investigate surgical strategy and outcome for cervical metastasis in different anatomical segments.Methods Data of 31 patients,who had undergone surgical treatment for cervical metastasis from 2001 to 2009,were retrospectively analyzed.Two anatomical regions were defined:upper cervical spine (C1 and C2)and subaxial cervical spine plus cervicothoracic junction (C3-T1).VAS score,Frankel grade,Tomita score and Karnofsky performance scale were used to evaluate pain,neurological status,expected survival time and general health.The improvement of symptoms,survival time and characteristics of surgical strategies for different anatomical regions were analyzed.Results Twenty-four patients were followed up successfully.An effective recovery in neck pain and quality of life was found after operation.The median survival time was 45.0 months.In upper cervical spine group,the surgical strategies included posterior occipitocervical fixation combined with 125I seed brachytherapy and other surgical methods,and the median survival time 48.0 months) of patients who underwent 125I seed brachytherapy was longer than that 22.0 of patients treated with other surgical methods.In C3-T1 metastasis group,patients who underwent combined anterior-posterior approach total spondylectomy had a longer survival time than those treated with anterior corpectomy.Conclusion Surgical treatment can effectively relief neck pain,maintain or improve neurological function and improve quality of life.Doctors should choose different surgical strategies according to anatomical region of cervical metastasis.For upper cervical spine,the main purpose of surgery is to stabilize the cervical spine; the posterior occipitocervical fixation is usually chosen,and the 125I seed brachytherapy is useful in local control of metastasis.For subaxial cervical spine and cervicothoracic junction,the anterior corpectomy is usually chosen,and a combined anterior-posterior approach total spondylectomy can be used for patients with corresponding conditions.

Objective To investigate and analyze the demands of ethical review knowledge training among clinical investigators and determinants,thus to discuss countermeasures to optimize the training pattern of ethical review knowledge training among clinical investigators and to provide scientific evidence and proposals for training management.Methods A total of 366 clinical investigators from third-class and first-grade general hospitals in Beijing were surveyed by questionnaires according to stratified random sampling method based on the professional titles,and the results were analyzed by SPSS 20.0.Results There existed training demands of ethical review knowledgeamong clinical investigators.For investigators with primary and intermediate titles,knowledge training about informed consent process,subject safety and rights protection,and principles of privacy security were highly needed.The training patterns researched were mainly short-term training and lectures organized by administrative department of the hospital.Most investigators expressed that the primary influence factor of training was lack of time and effort.Conclusions Based on the results of the survey,the demands of ethical review knowledge training are analyzed and countermeasures to optimize and enrich current training patterns are discussed,to improve the efficiency of training and the recognition and knowledge of ethical review among clinical investigators.

To better evaluate neuromuscular function of patients with stroke related motor dysfunction, we proposed an effective corticomuscular coherence analysis and coherent significant judgment method. Firstly, the related functional frequency bands in the electroencephalogram (EEG) were extracted via wavelet decomposition. Secondly, coherence were analysed between surface electromyography (sEMG) and sub-bands extracted from EEG. Further more, a coherent significant indicator was defined to quantitatively describe the similarity in certain frequency domain and phase lock activity between EEG and sEMG. Through the analysis of corticomuscular coherence during knee flexion-extension of stroke patients and healthy controls, we found that the stroke patients exhibited significantly lower gamma-band corticomuscular coherence in performing the task with their affected leg, and there was no statistically significant difference between their unaffected lag and the healthy controls, but with the rehabilitation training, the bilateral difference of corticomuscular coherence in patients decreased gradually.
