Aim To investigate the anticoagulant efficacy and mechanism of a semi-synthesized sodiumβ-1,4-glucan sulfate (Na-MCS). Methods Anticoagulant activity was evaluated by means of coagulation assays in comparison with heparin. The anticoagulant mechanism of Na-MCS was disclosed by inhibitory analysis of the activities of coagulation factors using chromogenic substrates. Results 0. 6concentration. The dosage of Na-MCS required to double APTT of normal human plasma was 0.7represented a potent anticoagulation activity in vitro, which matched the efficacy of heparin in a certain range of concentrations. Na-MCS exhibited anticoagulant activity due to inhibition of the coagulation factors Ⅱa and Xa by the mediation of anti-thrombin AT-Ⅲ.

BackgroundThe study of the molecular mechanism of visual plasticity is helpful for the explaining and prevention of strabismus and amblyopia.The effect and significance of NogoA in the strabismus and amblyopia formation are attracting more attention.ObjectiveThe present study was to investigate the expression of NogoA in 21a area of visual cortex in strabismic-induced amblyopia cats and explore the possible molecular mechanism of strabismic-induced amblyopia.MethodsSixteen 4-week old clean cats were randomizedly divided into normal group and strabismic-induced amblyopia group and eight for each group.The strabismic-induced amblyopia models were created by cutting off the external rectus in 8 cats.Pattern visual evoked potentials ( P-VEP ) were recorded 1 week after operation and compared with normal cats,and depression of amplitude and prolongation of implied time of P100 wave were as the successful criterion of model.The 200 ml paraformaldehyde was infused via heart to fax the brain under the deep anesthesia and then the cats were sacrificed and the brain cortex sections were prepared.The morphology of 21a zone of cat visual cortex was examined by haematoxylin and eosin staining,and the expressions of NogoA in 21a area of visual cortex were detected by immunohistochemistry with a monoclonal antiNogoA antibody.The use of the animals complied with the Regulations for the Administration of Affair Concerning Experimental Animals by State Science and Technology Commission.ResultsThe implied time and amplitude ratio of VEP P100 wave were (98.10±7.07)ms and (0.83±0.14) in normal group,and those in strabismic-induced amblyopia group were (108.50±6.95 )ms and (0.35 ±0.09 ),showing significant differences between two groups (t=4.450,P=0.005 ; t =5.970,P =0.005 ).The numbers of neurons were similar in 21a area of visual cortex between the two groups,but the volume of the neurons was lessen in strabismic-induced amblyopia group.The positive cell densities for NogoA were ( 387.37±2.01 ) cells/mm2,( 354.58± 1.85 ) cells/mm2 and ( 289.68± 1.81 ) cells/mm2 in layer Ⅱ/Ⅲ,Ⅳ and V/V[ respectively in strabismic-induced amblyopia group,and those in normal group were ( 161.39± 1.98 ) cells/mm2,( 128.93 ± 1.26 ) cells/mm2 and ( 96.25 ± 1.49 ) cells/mm2,indicating a significant increase in model cats ( t =- 160.400,- 201.890,- 164.740,P =0.000 ).Conclusions NogoA may play an important role in the regulation of the sensitive developmental period of visual sense and its plasticity.

OBJECTIVETo research the application and clinical effect of titanium elastic nails (TEN) for the treatment of closed clavicular fracture in elder children.

METHODSFrom October 2010 to December 2012,16 elderly children with clavicular fracture of elder children were treated with internal fixation, including 9 boys and 7 girls with an average age of 14.2 yeats old ranging from 9 to 17 years. The mean time between injury and surgery was 2 to 6 days. Thirteen patients had a transverse fractures; 3 patients had a oblique fractures, excluding the long-oblique patients. Neer function score after 3 months follow-up and the shoulder activity degree after 3 weeks followed were compared respectively between the injured side and healthy side. Fracture reduction and healing were followed up by X-rays to analyze internal fixation with TEN technique.

RESULTSAll patients were healed well after surgery. There were 2 cases with soft tissue irritation. No cases of infection, TEN broken, delayed healing or skin bursting were observed. All patients were followed up for 3 to 10 months,with an average of 7.2 months. There were no significant differences (t=2.12, P>0.05) between the healthy side (98.75±2.70) and injured side(96.69±6.22)of Neer score at 3 months during followed up. The shoulder activity at 3 weeks during followed up was different between both sides (P<0.05). The intramedullary nail was removed after X-rays at 12-18 weeks during followed up showed good bone healing,and the shoulder function was recovered well.

CONCLUSIONInternal fixation with TEN for the treatment of clavicular fracture has advantages of a limited invasion, beauty, safety and reliability. This technique provides an ideal fixation option for the treatment of clavicular fracture in elder children.

Objective To evaluate the effect of the expression of P-glycoprotein (P-gp) in the tumor tissue on the analgesic efficacy of fentanyl and lornoxicam in patients with cancer pain. Methods One hundred advanced cancer patients with pain aged 49-64 yr weighing $$-65 kg were included in this study. The expression of Pgp was positive in the tumor tissue in 50 patients (groups F1 and L1, n = 25 each) and negative in 50 patients (groups F2 and L2, n = 25 each). The patients in 4 groups received 48 h of pstient-controlled intravenous analgesia (PCIA). A loading dose of fentanyl 0.05 mg was administered before PCIA was started in groups F1 and F2 .The PCIA solution contained fentanyl 1 mg and droperidol 5 mg in 100 ml of normal saline in groups Ft and F2, or lomoxicam 64 mg and droperidol 5 mg in 100 ml of normal saline in groups L1 and L2. The PCA pump was set to deliver a background infusion of 2 ml/h and a bolus dose of 0.5 ml at 15 min lockout interval. Pain was assessed with VAS scores (0 = no pain, 10 = worst pain), and VAS score was maintained at ≤3 during PCIA. Flurbiprofen 50 mg was injected intravenously when VAS score≥4 and the consumption of flurbiprofen was recorded. The consumption of fentanyl and lornoxicam during PCIA was recorded. Blood samples from the internal jugular vein were taken at the beginning of PCIA (T0), and at 4, 12, 24, 48 h of PCIA (T1-4) for determination of blood fentanyl and lornoxicam concentrations. Results Flurbiprofen was not used in groups F2, L1 and L2. The consumption of flurbiprofen was ( 184 ± 41 ) mg in group F1 . There was no significant difference in the consumption of fentanyl during PCIA between groups F1 and F2 ( P ＞ 0.05). Blood fentanyl concentrations were not detected at all the time points in groups F1 and F2 . The VAS score during PCIA ≤ 3 in groups L1 and L2, and there was no significant difference in blood concentrations of lornoxicam at each time point and the consumption of lornoxicam during PCIA between groups L1 and L2 ( P ＞ 0.05). Conclusion Positive P-gp expression in the tunor tissue can decrease the analgesic efficacy of fentanyl, but exerts no effect on the analgesic efficacy of lornoxicam in patients with cancer pain.

OBJECTIVETo discuss the clinical effects and superiority of applying external fixation and bone transport to treat osteomyelitis and bone defect of femoral bone.

METHODSFrom August 2008 to December 2013,16 patients with osteomyelitis and bone defect of femoral bone were treated including 11 males and 5 females with an average age of 42 years old ranging from 13 to 62 years old. The average course of disease was 18 months ranging from 2 months to 4.5 years, and the average length of bone defect was 7.8 cm ranging from 4.5 to 15 cm. The bone defect of all cases were treated by external fixation and bone transport, the bone transport began at 1 week after operation, 1 mm per day and 4 times per day.

RESULTSAll patients were followed up for 10 to 36 months (means 22.5 months). One patient did not cooperate with treatment leads to the failure, then took the amputation. The remaining 15 cases of osteomyelitis were under control, including 12 cases of bone transport achieved one stage bone union, 3 cases achieved bone union via bone graft from iliac bone. The bone union time was 5 to 13 months(means 7.9 months). Thirteen patients almost obtained the same length of two lower extremities,2 patients had shortening of 1.5 to 2 cm. The time of moving the external fixation was from 6 to 16 months (means 9.3 months).

CONCLUSIONApplication of external fixation and bone transport is an effective method in treating the osteomyelitis and bone defect that can control the infection, eradicate wounds, and be the equalization of limb length.

Objective This study was conducted to measure the mandibular incisive canal (MIC) by cone beam computed tomography(CBCT)and to assess 3?dimensional structure, course and adjacent structure of the MIC , in order to ensure safe region for surgery of the mandibular interforaminal area. Methods A total of the CBCT images from 83 patients were studied and measured. The detection rates of MIC were calculated The diameter of the MIC and the distances from MIC to the labial and lingual cortices and the inferior border of the mandible and tooth tips were measured at canines and lateral incisors. Results MIC was found in 67.8%of the patients. In the position of canine, the diameter of MIC, the mean distance of the MIC to the tips of the teeth, to the buccal border of the mandible , to the lingual border of the mandible and the inferior border of the mandible were (1.3±0.4), (8.9±2.9), (4.3±0.9), (5.2±1.1) and (8.6± 1.5) mm, respectively. In the position of the incisor, the distance of MIC, the mean distance of the MIC to the tips of the teeth, to the buccal border of the mandible , to the lingual border of the mandible and the inferior border of the mandible were (1.0 ± 0.3), (13.3 ± 4.0), (4.2 ± 0.9), (5.9 ± 0.9) and (8.9 ± 1.8) mm, respectively. Conclusion CBCT clearly show three dimensional structure, course and adjacent structure of the MIC. Preoperative CBCT can provide vital information for surgery of the mandibular interforaminal area.

Objective To investigate the features of chronic prostatitis during puberty(CPP)and the effects of pelvic floor biofeedback therapy.Methods Totally,25 CPP children (mean age,16 years) and 15 children (mean age,16 years) with normal lower urinary tract as controls were included.In CPP group,NIH-CPSI scores were evaluated,expressed prostatic secretions (EPS) were examined,and bacterial culture was done;and CPP patients were categorized based on the definitions of NIH types.In both groups, urodynamic examination was performed,including evaluation of uroflow curve,maximum flow rate (Q_(max)), post-voiding residual urine (PVR),detrusor-sphincter dyssynergia (DSD),maximum detrusor pressure (P_(det,max))and maximum urethral closure pressure (MUCP).CPP patients underwent biofeedback therapy, and 10 weeks later the effects were assessed.Results In CPP group,NIH typing showedⅡ,ⅢA andⅢB in 1,3 and 21 cases,respectively.Before treatment in CPP and control groups,the incidence of staccato voiding (20 cases vs 1 case),DSD (22 cases vs 1 case),Q_(max)(10.7?3.7 vs 15.0?4.3ml/s),PVR (7.7?4.1vs 3.2?2.6ml),P_(det,max)(115.1?33.6vs 76.8?16.6cm H_2O)and MUCP(176.5?45.7 vs 86.2?28.5cm H_2O)all showed significant differences between the 2 groups(P＜0.05).In CPP group,the differences in pain(4.6?2.2 vs 2.1?1.6),urination (7.9?2.0vs 2.2?1.7),life impact (9.4?2.2vs 2.6?2.1)and total scores(22.0?5.2vs 7.0?4.2) of NIH-CPSI and Q_(max)(10.7?3.7 vs 14.9?5.6) between pre-and post-biofeedback were significant (P＜0.05).Conclusions The main type of CPP is categoryⅢB.The primary symptom is voiding disorder,which leads to greater psychological stress in patients.Children with CPP have pelvic floor dysfunctions and multiple abnormal urodynamic param- eters.The short-term effect of biofeedback strategies for CPP is satisfactory.
