Objective To evaluate the clinical efficacy of mini-invasive multichannel drainage in the treatment of hypertensive cerebral hemorrhage combined with severe ventricular hemorrhage. Methods The clinical data of 76 patients with hypertensive cerebral hemorrhage combined with severe ventricular hemorrhage were analyzed. They were divided into observation group and control group by random digits table method with 38 cases each. The patients in observation group were performed intracranial hematoma catheterized drainage combined with ventricle drainage under CT positioning, and the patients in control group were performed small bone window craniotomy combined with ventricle drainage. The conditions related to surgery and prognosis were compared between 2 groups. Results The operation time, blood loss and hospital stay in observation group were (46.2 ± 25.2) min, (35.4 ± 18.1) ml and (15.2 ± 2.5) d, and those in control group were (108.5±32.5) min, (112.5 ± 35.2) ml and (18.5 ± 3.2) d, there were statistical differences between 2 groups (P<0.01). Two cases died perioperatively in each group. The Glasgow outcome score (GOS) 1 month after operative in observation:9 patients were 5 scores, 19 patients were 4 scores, and the rate of better prognosis was 73.68%(28/38);in control group: 8 patients were 5 scores, 18 patients were 4 scores, and the rate of better prognosis was 68.42% (26/38). There was no statistical difference between 2 groups (χ2 = 0.256, P = 0.613). Conclusions Mini-invasive multichannel drainage is a safe and effective method for hypertensive cerebral hemorrhage combined with severe ventricular hemorrhage, and has the minimal invision.

Objective To develop a Chinese military psychosomatic health scale(CMPHS) and examine its reliability and validity. Methods Based upon the previous researches, the Scale was compiled according to open-ended inventory survey. The data was collected from 1050 subjects chosen by random cluster sampling. 60 of them were tested with the CPSHS at the same time, while 61 of them were retested with the CMPHS after two weeks. The reliability and validity were examined by exploratory factor analysis ( EFA) and correlation analysis. Results According to the factor analysis results, 11 factors were extracted, namely espiratory apparatus, alimentary system,skeletal and musculature,integument,regeneration and endocrine,nervous system, anxiety, depression, psy-choticism and family history. There were 91 items in the formal scale when one lie subscale was added. The correlation between subscales were 0. 103 ~ 0. 778 (P < 0. 01) , the correlation between subscales and total scale were 0.600 ~0.859(P<0.01). The test-retest correlation coefficients of total scale and subscales were 0.427 ~0.901 (P < 0.01); the Cronbach (α) coefficients were 0. 643 ~ 0. 935 (P < 0. 01) ; and the split-half correlation coefficients were 0. 349 ~ 0. 855 (P < 0. 01 ). The correlation coefficients were 0. 425 ~ 0. 979 (P < 0. 05 or 0. 01 ). Conclusion The Chinese military psychosomatic health scale has acceptable psychometrics properties on reliability and validity.

Objective To investigate the anesthetic management of perventricular closure of ventricular septal defects (VSD) under transesophageal echocardiography. Methods A retrospective review of the clinical data of 52 children who underwent perventricular closure of VSD under transesophageal echocardiography were analyzed. All the children were performed tracheal intubation under general anesthesia, and the electrocardiogram, pulse blood oxygen saturation, invasive arterial pressure, central venous pressure, end tidal carbon dioxide partial pressure, temperature and urine output were continuously monitored throughout the procedure. The transesophageal echocardiography was necessary for guiding transcatheter or per-ventricular device placement. Results Perventricular closure of VSD was successfully completed in 51 children under transesophageal echocardiography, the operation time was (76.7 ± 36.4) min, the anesthesia time was (89.5 ± 27.1) min; 1 child was converted to open surgical repair. Conclusions The intraoperative transesophageal echocardiography technology is the key to the success of the surgery. At the same time of analgesia and sedation, the anesthesia doctor needs to pay attention to the changes of hemodynamics in children.

Objective To study the construction of tissue engineering fat filler and the survival of fat particles.Methods Stromal vascular fraction (SVF) was derived from inguinal subcutaneous fat of rabbits,mixed with autologus mature fat particles and with or without neuropeptide Y to construct PLGA composite tissue.The complex was subcutaneously transplantef into back sites of the rabbits.Based on the different combination five groups were divided:Group A:PLGA + mature fat particles without NPY;Group B:PLGA + mature fat particles + NPY;Group C:PLGA + complex of SVF with mature fat particles without NPY;Group D:PLGA + complex of SVF with mature fat particles + NPY;Group E:Complex of SVF with mature fat particles + small ball with NPY.Diffenrence of virous constructive ways and fat particle survival was evaluated by general observation,histological staining,fluorescence tracing at two weeks,one month and three month after operation.Results Group D was superior to groups A,B,C and E in survival volume,graft texture and vascularization at one mouth and three mouths.The fat average srvival rate was 57.5±2.5%.Fat cell grew well,and precursor cells proliferated and differentiated actively.Conclusions High quality tissue engineering materials are successfully established with SVF-mature fat particle complex,PLGA and NPY,which could obviously improve fat particle transplantation.

Objective To observe the analgesic effects of dexmedetomidine combined with dif-ferent-doses of sufentanil in patients undergoing spine surgery.Methods Sixty patients(ASA grade Ⅰor Ⅱ degree,age 18-70 years)undergoing spine surgery were randomly assigned into three groups ac-cording to PCA formulation(n =20):3 μg/kg sufentanil group (group S1),1.5 μg/kg dexmedetomi-dine+ 2 μg/kg sufentanil group (group S2 )and 1.5 μg/kg dexmedetomidine + 1 μg/kg sufentanil group (group S3).The same anesthesia method was applied among three groups.Patient-controlled intravenous analgesia pump was applied before 30 minutes prior to the end of surgery.The drugs in each group were diluted to 1 50 ml and infused by a pump at a rate of 3 ml/h with a patient-controlled analgesia (PCA)bolus of 0.5 ml and lock time of 30 minutes.VAS and Ramsay scores at 2 h(T0 ),4 h (T1 ),8 h(T2 ),12 h(T3 ),24 h(T4 )and 48 h(T5 )after surgery were estimated.Postoperative nausea and vomiting,bradyrhythmia and hypersomnia were also recorded.Results Compared with group S1, VAS of groups S2 and S3 was significantly decreased at T1-T5 (P <0.05).There were also no signifi-cant difference in the incidence of postoperative nausea and vomiting,bradyrhythmia and hypersomnia among three groups.Conclusion Dexmedetomidine of 1.5 μg/kg can significantly reduce the dosage of sufentanil on postoperative analgesia in patients undergoing spine surgery,and decrease the rate of postoperative nausea and vomiting without any bradyrhythmia and hypersomnia.
