Objective To describe characteristic of sleep electroencephalograph (EEG) in depressions with psychogenic anxiety. Methods It was estimated for sleep EEG in 7 depressive patients with psychogenic anxiety,11 depressive patients with non-psychogenic anxiety and 10 normal controls. Results (1)Time from awake to getting up was significantly longer in non-psychogenic anxiety group than the normal subjects [(12.0?8.4)min vs(3.1?2.8)min,P0.05]. Conclusion (1)Time from awake to getting up is longer in non-psychogenic anxiety group than the normal subjects.(2)The tension of REM is higher in non-psychogenic anxiety group than the normal subjects.(3)It has tendency to be lower for tension of Rapid Eye Move in psychogenic anxiety group than the normal subjects.

Objective To investigate the effect of dexcedetomidine on the postoperative delirium in adolescent idiopathic scoliosis undergoing spine surgery. Methods 160 patients (7-16 years of age) with idiopathic scoliosis undergoing posterior spinal fusion were randomly divided in to two groups. Group SS (n=80) included patients anesthetized with sevorane and sufentanil, group SSD (n=80) included patients anesthetized with sevorane,sufentanil and dexcedetomidine. In the latter group, dexcedetomidine was administered as a continuous infusion of 0.2 ug/h started after the induction of anesthesia without a loading dose. Sevorane was adjusted to maintain the bispectral index (BIS) number at 40-60 and vasoactive drugs was adjusted to maintain the mean arterial pressure (MAP) at 65-75 mmHg. The amount of anesthetic, the time of anesthesia recovery,restlessness during recovery and postoperative delirium were recorded. Results The amount of sevorane, the incidence of restlessness during recovery and the incidence of postoperative delirium were significantly lower in the group SSD than in group SS ( <0.05) . Conclusion The perioperative infusion of 0.2 ug/h dexcedetomidine can decrease the incidence of postoperative delirium in adolescent idiopathic scoliosis undergoing spine surgery.

Objective To understand the clinical characteristics of pediatric patients who developed H1N1 influenza A virus-associated pneumonia during the outbreak of H1N1 influenza A in Shanghai. MethodsA dcscriptivc study was done to analyze the clinical and epidemiologic characteristics of 30 hospitalized children who developed complicated pneumonia caused by H1N1 influenza A virus infection in 2009 in Shanghai. The comparison of medians was done using rank sum test and comparison of rates was done using exact chi-square test. Results Among thirty pediatric patients with H1N1 influenza A virus-associated pneumonia, the median age was 5.9 years old, five cases (16.7 %) had pre-existing medical conditions. Twenty cases (66.7 % ) had been exposed to the classmates or family membcrs with fever. All cases had fever and cough. Eleven cases (36.7 %00 ) had tachypnca and ten (33.3%) had wheeze. Eleven cases (36.7%) showed white blood cell (WBC)＜4.0 × 109/L and 2 (6. 7%) had thrombocytopenia. All patients had bilateral or unilatcral patchy infiltrates in the lung indicated by chest X-ray and four (13. 3%) had extensive infiltrates with the evidence of pulmonary edema. One (3. 3%) critically ill child with pneumonia, chest computed tomography scan revealed lung fibrosis 3 months and 9 months after illness onset. Three(10. 0%) cases had pneumomediastinum and subcutaneous emphysema. Six cases (20. 0%) were complicated with acute respiratory failure, three (10. 0%) with acute asthmatic attack and one (3. 3%) with encephalitis. All patients were treated with oseltamivir plus antibiotics and four required mechanical ventilation. All patients survived. The median duration of fever in group with oseltamivir given within 2 days of fever onset was statistically shorter than that in group with oseltamivir given 2 days after fever onset (2 days vs 5 days, Z= -8. 015, P<0. 01). Conclusions Both pre-school age and schoolage children may develop complicated severe respiratory diseases after H1N1 influenza A virus infection. Early initiation of oseltamivir may shorten the duration of fever and reduce the occurrence of severe complications.

SUMMARY Pregnancy-related pelvic ring disease brings great suffering to pregnant women, including the separation of the pubic symphysis and sacroiliac joint pain.Hormonal changes leading to ligamentous laxity is the main reason for pregnancy-related pelvic ring disease.In normal pregnant cases, and the physiologic widening at the symphysis is about 3-7 mm.When the widening of the symphysis is more than 10 mm, it may lead to symptoms and need active treatment.Currently the diagnosis of the pubic symphysis separation is based on the clinical symptoms and signs.The treatment of acute pubic symphysis separation bases on conservative therapy, includes bed rest and physical therapy.But when the widening of the symphysis is more than 4 cm, the surgery intervention may be a good treatment.If the conservative treatment is not obviously effective, the surgery consists of plate fixation in the pubic symphysis and sac-roiliac screw fixation.Other indications for the surgical intervention include inadequate reduction, recur-rent diastasis, intractable symptoms, and open rupture.

Objective To discuss the clinical outcomes of trochanteric digastric osteotomy and surgical hip dislocation for treatment of Pipkin Ⅳ fractures. Methods We retrospectively reviewed the 12 patients with Pipkin Ⅳ fracture who had been treated by trochanteric digastric osteotomy and surgical hip dislocation from February 2012 to June 2016. They were 10 males and 2 females, with an average age of 44. 1 years ( from 24 to 63 years ) . According to the Pipkin classification for femoral head fractures, 9 fractures were type Ⅰand 3 type Ⅱ; according to Letournel-Judet classification for acetabular fractures, 10 were posterior wall fractures ( 9 belonging to the posterior superior subgroup ) and 2 transverse plus posterior wall fractures ( one involving the posterior wall belonging to the posterior superior subgroup ) . The operation time, blood loss, complications and functional results were recorded. Results The operation time averaged 165 min ( from 150 to 195 min ); the blood loss averaged 850 mL ( from 500 to 1, 200 mL ) . A spring plate was used additionally for posterior wall fracture in 7 cases. All the 12 cases obtained an average follow-up of 19 months ( from 6 to 52 months ) . Motion function was fully recovered from 6 weeks to 4 months after operation in 2 cases of preoperative incomplete sciatic nerve injury and in one case of iatrogenic incomplete sciatic nerve injury. Anatomical reduction was achieved in all femoral head fractures. According to the Matta criteria for acetabular fractures, anatomical reduction was achieved in 9 cases, good reduction in 2 and poor reduction in one. Heterotopic ossification occurred in 4 cases ( gradeⅠin one, gradeⅡin 2 and gradeⅢin one by the Brooker grading system ) . The trochanteric osteotomy was repeated in one case. No femoral head avascular necrosis was found. According to the modified Merle d'Aubigné and Postel scoring at the final follow-ups, the functional results of the affected hip were excellent in 4 cases, good in 7 and poor in one. Conclusion Trochanteric digastric osteotomy and surgical hip dislocation is a safe and effective treatment for Pipkin Ⅳ fractures.

Objective Combination of nanoparticle with p53 and Rb gene therapy by gene targeting was applied to investigate its curative effect and safety evaluation on colorectal rabbit hepatic VX2 metastasis for tumor eradication and survival enhancement. Methods Recombinant expressing plasmids harboring wild type p53 and Rb were cotransferred or transferred separately to the rabbit hepatic VX2 metastasis by the emulsion of PLL-nHAP nanoplex and lipodiol through the hepatic artery in a tumor target manner. Subsequent co-expressions of p53 and Rb protein within the treated tumors were detected by Western blot and in situ analysis of confocal laser scanning microscope. The therapeutic effect was evaluated by the tumor growth velocity and the survival time of animals. Eventually, investigations of liver function were applied to evaluate the safety of the process. Results With safe procedure for the rabbits liver function, both p53 and Rb local nano-therapy showed favorable anti-tumor effects and increased animal survival time. p53+Rb local nano-therapy could significantly inhibit hepatic VX2 metastasis and enhance the animal survival time compared with p53 local nano-therapy or Rb local nano-therapy. Local nano-therapy showed no significant influence to animal liver function. Conclusions Rb can work synergistically with p53 in the combined therapy mediated by PLL-nHAP nanoplex to augment the anti-tumor effect. The local nano-therapy with p53 and Rb is likely to be an effective and safe anti-tumor therapy for hepatic colorectal metastasis.
