Clinical Practice verified that the esophagusatrial pace technique canbe used to treat superventricular tachycardia,but the therapeutic effect is not ideal to atrialventricular node reentrant tachycardia.We adopted intraheart electronic pulse stimulation which could get satisfactory effect.It is considereb that it is a new the- rapeutical method of superventricular tachycardia.

Chronic cerebellar stimulation is a new methed to treat intractable epilepsy which is based on electrophysiological characteristics of excitation and inhibition of the central nerve system. The clinical tests have shown that the chronic cerebellar stimulation can get improvement of EEG,reduce the somatosensory inductive potentials and H-reflexes,and reduced seizures in numbers.

The necessity and importance of medical equipment quality control are analyzed on the basis of clinical cases of ventilator using.It is necessary because it assures the technical performance in the process of medical diagnosis and treatment.It is important because it extends the work range of medical engineers in hospital,changing them from the state of passive maintenance to active quality control,thus contributing to the combination of engineering and clinical diagnosis and treatment.Further more,it promotes the development of clinical medical engineering in hospital.

Objective To approach the main symptoms and pulses of excessive rising of live yang in hypertensive disease. Method The symptoms and pulses of excessive rising of liver yang in hypertensive disease were collected through clinical epidemiology. The frequency of single symptom and pulse or their combinating group was statistical analyzed by multiple factor cluster analysis and principal component analysis. Result Such symptoms and pulses as lightheadedness,headache,distention of head,tantrum,insomnia,dizzy,bitter taste of mouth,red tongue,yellow tongue fur and string pulse not only can reflect the main pathogenesis,but also are the most frequently occurring reflection. Conclusion Symptoms and pulses above are the differentiation of symptoms and signs standard for excessive rising of liver yang in hypertensive disease.

Background:It was demonstrated that vitamin D has extensive biological effects,and evidence exists on association between vitamin D and a variety of immune mediated diseases such as inflammatory bowel disease. Aims:To investigate the relationship between serum level of 25-hydroxyvitamin D(25OHD)and disease activity and quality of life in patients with ulcerative colitis( UC). Methods:Serum level of 25OHD was detected by electrochemiluminescence in 50 outpatients/inpatients with UC from Oct. 2015 to Mar. 2016 at the Anhui Provincial Hospital;35 healthy subjects were served as normal controls. CRP,ESR and PLT were determined by routine laboratory tests in UC patients. Disease activity of UC was assessed by improved Mayo score,and Chinese version IBD questionnaire( IBDQ)was employed to assess quality of life. Results:Vitamin D deficiency defined as serum 25OHD ﹤20 ng/mL was detected in 68. 0% of the UC patients. The mean value of serum 25OHD was significantly lower in UC group than in normal control group[(16. 73 ± 8. 83)ng/mL vs.(19. 84 ± 4. 56)ng/mL,P﹤0. 05]. When patients were stratified with disease activity,serum level of 25OHD decreased in the order of remission,mild,moderate and severe active stage(P ﹤0. 05). In UC patients with vitamin D deficiency,the value of CRP,ESR and PLT were significantly increased(P all ﹤0. 05)and the overall score of IBDQ and scores of four dimensions of IBDQ referring to bowel symptom,systemic symptom,emotional function and social function were significantly decreased(P all ﹤0. 05). Spearman and Pearson correlation coefficients analyses showed that serum level of 25OHD was negatively correlated with Mayo score,CRP,ESR and PLT(P all ﹤0. 05),and positively correlated with scores of IBDQ,including overall score and four dimensional scores in UC group( P all ﹤0. 05 ). Conclusions:Vitamin D deficiency occurs frequently in patients with UC and might have a negative impact on disease activity and quality of life.

Objective To compare with the effect of high-frequency repetitive transcranial magnetic stimulation (rTMS) between the left and the right prefrontal on refractory negative symptoms and serum brain-derived neurotrophic factor (BDNF). Methods 80 hospitalized schizophrenics with refractory negative symptoms were divided into study group (n=40) and control group (n=40) randomly. Both groups were received 4-week treatment of 10 Hz rTMS. The stimulus lo?cation of the study group was the left prefrontal, and the control group was the right prefrontal. The type and dose of anti?psychotics remained unchanged during the treatment. The evaluation of positive and negative symptom scale (PANSS) and the measurement of BDNF concentration before treatment and after 4 weeks treatment was analyzed. Results Com?pared with before treatment, the total score of PANSS after treatment significantly decreased (P<0.05) both in the study group [(71.2±13.8) vs. (63.3±11.4)] and the control group [(70.3±13.4) vs. (63.7±12.2)]. The score of negative symptoms in the study group decreased [(22.8±6.6) vs. (18.4±5.9), P<0.01]. The BDNF concentration increased in the study group ](6.78±2.16) vs. (8.74±2.76)] and the control group [(6.83±2.32) vs. (8.66±2.70)]. Conclusion 10Hz rTMS on the left pre?frontal combined with drugs are helpful to improve the refractory negative symptom of the patients with schizophrenia. Stimulation on both left and right prefrontal lobe could increase serum BDNF concentration.

Objective To investigate the clinical outcomes of hemiarthroplasty with Wagner SL prosthesis in treating failed internal fixation of intertrochanteric fractures of elderly patients.Methods Aretrospective case series study was conducted on the clinical data of 14 patients with failed internal fixation of intertrochanteric fractures admitted between March 2015 to April 2018.There were seven males and seven females with a mean age of 82.2 years (range,75-94 years).The primary internal fixators were proximal femoral nail anti rotation in nine patients,dynamic hip screw in three patients,and proximal femoral locking plate in two patients.The main causes of internal fixation failure were screw loosening in six patients,cutting out of screws in five patients,nonunion in two patients,and plate breakage with nonunion in one patient.Affected limb shortening and coxa varus deformity to various degrees were seen in all the patients before operation.The mean interval from internal fixation to hemiarthroplasty was 6.6 months (range,2-12 months).All patients received hemiarthroplasty using Wagner SL prosthesis,of which nine patients had additional trochanter claw plate with titanium cable fixation and two patients had tension band wire fixation.The operation time,intraoperative,and postoperative complications were recorded.Harris hip scores were measured before operation and at the last follow up to evaluate hip function.Radiographs were performed to assess the fracture healing,prosthesis position,and biological fixation.Results All patients were followed up for 6-30 months (mean,14.5 months).The mean operation time was (108.0 ± 12.4) minutes (range,88-130 minutes).No iatrogenic fracture occurred during the operation.One patient was seen contralateral intertrochanteric fracture during follow-up,and no complications such as periprosthetic fracture,prosthetic sinking,and infection occurred in the 13 patients.The Harris score increased from (26.1-±7.5)points before operation to (83.1 ±4.1)points after operation (P ＜ 0.01).All patients were able to stand and walk,of which four needed crutch assistance.At the last follow-up,X-ray film showed that the prosthesis was well positioned and that all of them reached bony fixation.Fourteen cases of greater trochanteric fracture were healed,with two cases of slight displacement.Conclusions Hemiarthroplasty is an effective remedial treatment for failed internal fixation of intertrochanteric fractures in the elderly,which can improve hip function and enhance the life quality of patients.Wagner SL prosthesis can obtain stable fixation.
