Objective To examine plasma inflammatory cytokines and assess stress response in different general anesthesia schemes in cesarean operation. Methods Sixty caesarean operation puerperas were randomly divided into two groups, including the group of sevoflurane (Group S) and the group of propofolum (Group P) in 30 cases of each group. At different time point, we recorded the mean arterial pressure and heart rate, text the blood concentration of inflammatory cytokines; The Apgar scores and arteria umbilicalis pH value after baby delivery were recorded. Results The blood pressure and heart rate of the P group after anesthesia induction of baby in delivery were lower than that before the anesthesia induction(P < 0.05). And there were also significant differences when compared with the S group (P < 0.05). The blood concentration of IL-6 and TNF-α of the P group afte operation were higher than that before the anesthesia induction(P < 0.05). There were also significant differences when compared with the S group(P < 0.05). The blood concentration of sTNFRⅡof the P group after operation and 24 hours after the surgery were higher than that before the anesthesia induction (P < 0.05). And there were also significant differences when compared with the S group (P < 0.05). Conclusion Administering Sevoflurane compound with Remifentanil to general anesthesia in Caesarean operation is safty and steady to inhibit stress reaction and prevent explicit memory from the operation.

Attention-deficit/hyperactivity disorder (ADHD)is one of the most common comorbidities of ASD.This article reviews the assessment tools and clinical research (prevalence,clinical characteristics and treat-ment)and fundamental research (iconography,genetics,neurophychology,electronerophysiology)of ASD with ADHD according to lately related articles.The findings suggested that there was lack of researches on treatment and iconography of ASD with ADHD and the conclusions were inconformity.Furthermore,most of the objects in these researches were children of normal intelligence.Thus future research should expand its objects to patients of adult and children with mental retardation and do further explore in iconography and treatment.

Objective To explore the clinical efficacy of one-stage cannulated screw fixation in treatment of tibial avulsion fracture at the insertion of posterior cruciate ligament(PCL) under posterior direction version and in treatment of tibial avulsion fracture at the anterior cruciate ligament (ACL)under arthroscopy.Methods From January 2010 to June 2015,25 patients with tibial avulsion fractures of the posterior cruciate ligament combined with the anterior cruciate ligament in our hospital were retrospectively analyzed.Firstly,arthroscopic exploration was conducted in all patients in their horizontal position,aiming to observe whether combined injures existed or not and to confirm fracture fragments and the degree of tibial avulsion fractures of the cruciate ligaments.All patients recieved arthroscopic fragment fixation by using cannulated screws,then,were treated with a minimally posteromedial incision in the prone position by cannulated screw fixation.All knee joints were protected by adjustable orthopedic brace for 4-6 weeks.The clinical knee joint function of patients were measured by using International Knee Documentation Committee (IKDC) scoring scale and Lysholm scoring scale.The X-ray or CT image were used to evaluate healing process of the fractures.Results All patients were followed up for 6-24 months,the median follow-up time was 15 months.All fractures healed in one stage,time of fracture healing ranged from 9 to 24 weeks,and the median time was 12 weeks.The average IKDC scores at the finial follow-up were as follows:claudication (4.88±0.29)points,support (4.65±0.36)points,pain (4.78±0.49)points,swelling (4.88±0.52)points,squat (4.85±0.35)points,all were higher than those before operation,there were statistically significant differences when compared with those assessed before operation (P<0.05).The average Lysholm score at the finial follow-up was (93.4±2.8)points,the rate of excellent and fine was 96.0%,no statistically significant difference was found compared with that at the healthy side (P>0.05).Conclusion The one-stage cannulated screw fixation in treatment of tibial avulsion fracture at the insertion of PCL under posterior direction version and in treatment of tibial avulsion fractures at the ACL under arthroscopy is easy and convenient to operate,which has the advantages of reliable fixation and satisfactory recent curative efficacy.

BACKGROUND:Kalikrein 1 is an important component of the kalikrein-kinin system. Studies have shown that kalikrein can protect the cardiovascular system by promoting angiogenesis and inhibiting myocardial inflammation, but there is no report on its effect on inducing differentiation of stem cels. OBJECTIVE: To determine the transfection efficiency of kalikrein 1 adenoviral vector in rat bone mesenchymal stem cels. METHODS:Using adenovirus as a vector, the target gene kalikrein 1 was transfected into rat bone marrow mesenchymal stem cels. Fluorescence microscopy, MTT method and flow cytometry were used to investigate the effect of transfection and determine the optimal multiplicity of infection. RESULTS AND CONCLUSION:Adenovirus carrying kalikrein 1 was successfuly transfected into rat bone marrow mesenchymal stem cels. Results from flow cytometry showed that the transfection efficiency was associated with the multiplicity of infection. When the multiplicity of infection was 150, the transfection efficiency was 80.8%. MTT results showed that when the multiplicity of infection was 200, the cel growth was inhibited remarkably. These findings indicate that adenovirus-mediated kalikrein 1 can be successfuly transfected into rat bone marrow mesenchymal stem cels with the optimal multiplicity of infection=150.

The object of this study is to preparate the berberine hydrochloride (BBH) resin compound with taste masking effect. We took the BBH as the model drug and Amberlite IRP69 as the drug carriers, uncovered the curve of solubility of BBH in different cosolvent with a certain range of temperature, and then used it to calculate the parameters during the preparation of the complex such as adding quantity of BBH and the reaction temperature. Afterwards, the characteristic and in vitro release experiments were studied to verify the formation and predict the in vivo release behavior of the complex. The results showed that in the condition of using 60% ethanol as a cosolvent and stirring at 50 ℃ for 1 h, the drug loading and drug availability of the complex are at about 35% and 64%, respectively, and has a better taste-masking effect. In this study, a method was provided for preparing a taste-masking preparation of BBH.

OBJECTIVETo explore the therapeutic effects of internal fixation with Herbert screws for the treatment of Pipkin type I and type II femoral head fractures.

METHODSFrom January 2008 to December 2012, 23 patients with Pipkin type I and type II femoral head fractures were treated with open reduction and internal fixation by Herbert screws through Kocher-Langenbeck approach. Twenty-three patients (aged 18 to 52 years with a mean of 35.5 years, including 18 males and 5 females patients, 8 left hips and 15 right hips) with femoral head fractures and posterior hip dislocation. The fracture was classified according to Pipkin classification based on the radiographic findings, 5 patients had type I and 18 had type II fractures. The duration time from admission to the operation ranged from 6 to 72 h (averaged 32 h). The clinical and radiographic outcomes of the patients were measured using Thompson-Epstein scoring scale. The Harris hip score(HHS) was used to evaluate and compare hip functions at the latest follow-up between affected and healthy sides.

RESULTSAll the patients were followed up, and the duration ranged from 20 to 48 months (averaged 30 months). According to Thompson-Epstein system, 12 patients got an excellent result, 6 good, 4 fair and 1 poor. The average HHS at the finial follow-up was 87.80 ± 8.46 (ranged from 66 to 95), which is similar to that in the healthy side 90.10 ± 6.35 (ranged from 72 to 98) (t = 1.044, P = 0.302). The complications such as deep infection, and deep vein thrombosis were not found. At the 3rd year during follow-up,4 patients had avascular necrosis of femoral head. At the 1st year of follow-up, 1 patient had hip pain after walking,screws loosening and shift after trauma,and serious complications of traumatic arthritis. All the 5 patients were treated with total hip arthroplasties.

CONCLUSIONThe treatment of internal fixation with Herbert screws through the Kocher-Langenbeck approach is effective for Pipkin type I and type II femoral head fracture. The method is reliable and valuable for recommendation. However, such fracture may have avascular necrosis of femoral head and complication of traumatic arthritis, which should be observed carefully in clinic with preparation of the prevention and treatment measures.

Objective To study the effects of preconditioning treadmill exercise on excitatory amino vacid changes in rats after the cerebral infarction and the protective effects against cerebral isehemia brain injury. Methods Thirty Sprague-Dawley rats were used in this study. Twenty-five rats were subject to an operation to establish the animal model of middle cerebral artery occlusion and divided into a isehemia group, an 1-week ex- ercise group (trained in the 4th week) , a 2-week exercise group (trained in the 3rd and 4th weeks) and a 4- week exercise group (trained for 4 weeks) , while the remaining 5 rats were subject to sham operation, and served as the controls. After 4 weeks of experiment, all the the rats were fixed on stereotactie apparatus for the brain microdialysis of the striatum. Then the focal middle cerebral artery ischemia and reperfusion were made with thread oeclussion in rats and microdialysis technique was used to collect extraeellular fluid in each period of pre-ischemia, ischemia (40, 80 and 120 min), and reperfusion (40, 80, 120, 160, 200 and 240 min) to detect the changes of the excitatory amino acid. At the same time the infarction volume was also measured at 24 hours after ischemia-reperfusion of the brain. Results The difference between any two groups was significant with regard to the volume of cerebral infarction (P < 0.05). Two weeks and four weeks of the preconditioning treadmill exercise couled significantly reduce concentration of Glu excessively released due to the ischemia (P < 0.01). Conclusion At least two weeks of preconditioning treadmill exercise can inhibit the excessive release of the important excitatory amino acid neurotransmitter glutamate, to some extent, in the process of the subse- quent ischemic brain injury and during reperfusion, which might be one of the protective mechanisms of move- ment against the early isehemie brain injury.
