Objective To investigate the effect of acupuncture at Sanyinjiao with functional magnetic reso- nance imaging(fMRI),analyse the regulating effect of the acupoint Sanyinjiao on various brain areas,explore the mechanisms of Sanyinjiao(SP.6) acupuncture in treating diseases.Methods Eight right-handed healthy volun- teers were scanned at 1.5 Tesla magnetic resonance imaging scanner while they were aeupunctured at the right Sany- injiao acupoint.Image data were co-registered to correct head motion,spatial normalization and deconverlution analy- sis were conducted.Functional activation maps were generated.Results There observed certain activation in both sides of medial frontal gyrus,right middle frontal gyrus,left inferior frontal gyrus,both sides of paracentral lobule, precentral gyrus and postcentral gyrus,left inferior parietal lobule,both sides of preeuneus,right middle temporal gy- rus,right cingulated gyrus,posterior cingulated gyrus,both sides of superior temporal gyrus,transverse temporal gy- rus,insula and thalamus.Conclusion Acupuncturing the Sanyinjiao can lead to the functional changes in parietal lobe,frontal lobe,temporal lobe and insula,precuneus,cingulated gyrus,thalamus,which are closely related to the therapeutical effects of Sanyinjiao.The phenomenon that needling Sanyinjiao can activate certain brain areas proved the correlation between acupoint and corresponding brain cortices.

Objective To explore the application of high-frequency oscillatory ventilation(HFOV)postoperatively after open heart surgery in children with congenital heart disease.Methods From Jun.2007 to Jun.2008,a total of 1 957 cases were operated in pediatric center of Fuwai cardiovascular hospital.Thirteen cases of 1 957 were given HFOV.Among these 13 patients,8 were male and 5 were female;Age was(13.4?15.4)months.The range of weight was 4.2-12.5 kg.Four cases were tetralogy of Fallot,3 cases were transposition of the great arteries(1 case was corrective transposition of the great arteries),2 cases were total anomalous pulmonary venous connection,2 cases were total endocardial cushion defects,2 cases were pulmonary artery atresia,all patients were under cardiopulmonary bypass repaired operation except 1 patient with PAA under Blalock-Taussig procedure.All patients were mechanical ventilated after surgery.Results The duration of switching general mechanical ventilation to HFOV was(15.70?20.33)days and patients continued to be on HFOV about(10.0?7.5)days.In short term,the lung function of ventilation and gas exchange were be improved by HFOV,but the long-term result was not sa-tisfactory due to a high mortality.There were 5 survived(38.4%)in this group.Six cases of the patients succumbed to consolidation of lung.The commonest complication was pneumothorax(7 cases).Conclusions Short term of HFOV in children with congenital heart disease was satisfactory postoperatively.But there was a high mortality.HFOV can be regarded as a transition method for unsatisfactory long-term.

OBJECTIVETo compare clinical outcomes of swing shoulder and internal fixation in treating proximal humeral fractures.

METHODSFrom June 2007 to June 2012, totally 89 elderly patients with humeral proximal fractures were treated by swing of shoulder or internal fixation, and 81 patients were followed up. In swing shoulder group, there were 38 patients including 13 males and 25 females aged from 62 to 84 with an average of (67.11±6.18) years old; 27 cases were 2-part fractures and 11 cases were 3-part fractures according to Neer classfication. In internal fixation group, there were 43 patients including 16 males and 27 females aged from 60 to 80 with an average of (66.47±5.48) years old; and 29 cases were 2-part fractures and 14 cases were 3-part fractures according to Neer classfication. VAS score and complications were compared between two groups after treatment, and Constant-Murley functional scoring was used to evaluate shoulder function of patients.

RESULTSEighty-one patients were followed up from 13 to 26 months with an average of 18.3 months. There was no significant difference in preoperative VAS score between two groups. After treatment, VAS score in swing shoulder group was (3.11±0.95), and (3.88±1.14) in internal fixation group, and had significant difference between two groups (t=-3.313,P<0.05). There was no significant difference in Constant-Murley scores between swing shoulder group (79.53±3.73) and internal fixation group (77.98±4.11) (t=1.768,P>0.05). Postoperative complications in swing shoulder group was 18.4%(7/38), 39.5%(17/43) in internal fixation group, and had significant differences between two groups (χ2=4.313,P<0.05).

CONCLUSIONSwing shoulder for the treatment of proximal humeral fractures in elderly has advantages of low cost, less complications and good recovery of joint function; while internal fixation has a good therapeutic effect but increased complications.

ObjectiveToinvestigatethekidneyyangdeficiencyconstitutionandhypothalamus-pituitary-adrenal ( HPA) axis dysfunction in Lewis rats .Method Two kidney yang deficiency models were established by subcutaneous injection of hydrocortisone and by adrenalectomy to induce hypothalamic -pituitary-adrenal ( HPA) axis dysfunction in Lewis rats.Wistar rats were used as control and compared with the two types of Lewis rat models of kidney yang deficiency .The degree of kidney yang deficiency of the Lewis rats was evaluated by examination and detection of the general signs , behavior , and neuroendocrine function , and so on .Result Compared with the normal Wistar rats , the body weight of Lewis rats was significantly higher than that of Wistar rats at the same age .The body temperature , urine volume and grip strength were significantly lower than those of Wistar rats ( P<0.01 for all ) .The memory ability of the Lewis rats was slightly decreased.The liver, kidney and adrenal indexes were significantly decreased in the Lewis rats (P<0.01).The levels of serum ACTH, CRH, cGMP, Cort and urine 17OHCS were significantly decreased (P<0.01).Conclusion A very slight deficiency of adrenal cortex function of Lewis rats is caused by genetic inheritance , and Lewis rats have the constitution of congenital kidney yang deficiency ( criticality or prophase of kidney yang deficiency ) .

OBJECTIVETo review the efficacy of total anomalous pulmonary venous connection (TAPVC) repair and to conclude the factors impacting the peri-operative death rate.

METHODSThe clinical data of 145 infants under 1 year old who underwent the TAPVC repair from January 2001 to July 2008 was analyzed. There were 94 male and 51 female patients. The mean age when the repair was performed was (7 ± 3) months, and the average weight was (6.3 ± 1.6) kg. As to the pulmonary connection type, 77 patients were supracardiac (53.1%), 47 patients were cardiac (32.4%), 9 patients were intracardiac (6.2%), and the remaining 12 patients were mixed (8.3%). Pre-surgery echocardiography showed that 21 patients had pulmonary venous obstruction (12 patients were supracardiac type, 3 patients were cardiac type, 3 patients were intracardiac type, and 3 patients were mixed type).

RESULTSAll patients underwent two-ventricle anatomy correction (the cases of complex malformations had been excluded). Peri-operative mortality was 11.7% (17/145). Because of the significant improvement in the surgical techniques, anesthesiology, cardiopulmonary bypass and the management of ICU in January 2006, the population was divided into two groups: A (before January 2006) and B (after January 2006). Peri-operative mortality decreased from 19.0% in group A to 6.2% in group B(P = 0.020). After analysis, it was determined that the factors impacting mortality were which group the patient belongs to, whether he/she had preoperative pulmonary vein obstruction and how big the atril septel connection was. The operative technique to keep the anastomotic aperture adequate and prophylaxis pulmonary hypertensive episodes contributed to the improvement on the mortality rate. There had been no case of repeating the surgery because of pulmonary venous obstruction during peri-operative care period.

CONCLUSIONSImprovements of the surgical technique as well as the treatment in preoperative and postoperative have led to the reduction of the mortality. Preoperative pulmonary vein obstruction is still an important factor that contributes to early mortality.
