[Objective] To discuss the therapeutic effect of different methods in the treatment of intertrochanteric femur fracture. [Methods]Totally 118 middle aged or old patients with intertrochanteric femur fracture were fixed with dynamic hip screw (DHS), Gamma nail or PFNA.[Results]Totally 112 cases were followed up, and the average time was 16 months, in those 45 patients were fixed with DHS: 29 were excellent, 11 cases were good, and 5 were poor, and the excellent to good rate was 88.9%; 36 patients were treated with Gamma nail, and the excellent, good, poor results were 28, 2, 1, respectively, and the excellent to good rate was 96.8%; 36 patients were fixed with PFNA, and the excellent, good, poor results were 29, 6, 1, respectively. The differences were significant (P=0.02, analyzed by Logistic regression with SPSS software). The excellent and good superiority of Gamma nail and PFNA were 5.1552 and 2.3726 times compared to DHS, and there was significant differences between the groups.[Conclusion]Surgical treatment of intertrochanteric femur fracture can improve the functional recovery and reduce the complication incidence, and PFNA fixing method can shorten the operative time, reduce the bleeding and the therapeutic effect is reliable, and suitable for old patients combined with osteoporosis.

The humanistic thinking of life philosophy of traditional Chinese medicine (TCM) observed inlife activities is different from western theories and methods,which is more about life experience and feeling and rich in practical significance.The life philosophy of TCM is also different from traditional Chinese culture.The intuitive feeling of life is one of the main characteristics of life philosophy of TCM.Students of TCM soak in traditional Chinese medicine culture and are influenced by the thinking of real life caused by the care of realbody in TCM.Chinese medicine education should fully mobilize the tacit knowledge of life education in TCM,play excellent tradition of Chinese traditional life philosophy,and cultivate the life moral quality in students of TCM.

Conclusion The Stago STA-R automatic blood coagulation analysis system has good analytical performance ,can provide accurate and reliable test results for clinical doctors .

Objective It has been shown that ketamine and magnesium used in combination provide more effective analgesia than either drug alone. The purpose of this study was to investigate the effects and interaction of the two drugs on recombinantly expressed NMDA receptors. Methods Xenopus oocytes expressing NR1/NR2A or NR1/NR2B glutamate receptors were stimulated with glutamate/glycine and studied at a holding potential of -70mV using two electrode voltage clamp. The effects of magnesium and s ( + )-ketamine alone or in combination on NMDA signaling were determined. Results Magnesium and s( + )-ketamine alone inhibited NMDA receptors non-competitively. IC50s of magnesium were (4.2 ± 1.2)×10-4mol/L and (6.3 ± 2.4) × 10-4 mol/L on NR1/NR2A and NR1/NR2B, while IC50s of s( + )-ketamine on NR1/NR2A and NR1/NR2B were (4.1 ± 2.5) × 10-6 mol/L and (3.0 ± 0.3 ) × 10-6 mol/Lrespectively. Magnesium and s( + )-ketamine used in combination decreased IC50s more than 90% at both receptors. Isobolographic analysis demonstrated superadditive interactions. Conclusions s( + )-ketarnine and magnesium inhibit responses of recombinantly expressed NMDA recptors non-competitively, and the combinations of the two drugs produces a synergistic effect.

Objective To observe the dyskinesias and motor fluctuation in patients with Parkin-son’s disease, and investigate their influential factors. Methods The detail information of dyskinesias and motor fluctuation of 63 patients with Parkinson’s disease were recorded and followed up when the of L-Dopa therapy was carried out, and all patients were assessed by using UPDRS at “on” and “off” stage, Hoehn and Yahr scale, Schwab and England living scale.The data were calculated with SPSS 10.0 statistic software. Results All patients received alone or combined L-Dopa therapy.Among the 63 patients, 11 (17.5%) were experienced dyskinesias, in which 10 show dystonia; and 36 were (57.1%) experienced motor fluctuation, in which 28 developed wearing-off.The mean daily dose of L-dopa and score of UPDRS in “off” stage were positively correlated with dyskinesias.The duration of therapy with L-dopa was positively correlated with motor fluctuation.The controlled release cabidopa/levodopa was in negative correlation. Conclusions The rate of motor fluctuation was approximately equal to the results reported in other countries.The dyskinesias was lower in occurrence and the mean daily dose of L-dopa and the disease severity should be the main influencing factors to the dyskinesias.The duration of therapy with L-dopa should be influencing factor to motor fluctuation.The main subtype of motor complications should be dystonia and wearing-off.

Objective: To evaluate the depression and anxiety in patients with sleep apnea-hypopnea syndrome (SAHS). Methods: Fifty patients with SAHS were diagnosed with polysomnography (PSG) and 30 healthy controls underwent whole-night PSG monitory and evaluated by Zung Self-rating Depression Scale (SDS) and Zung Self-rating Anxiety Scale (SAS). Results: The total scores of SAS and SDS in SAHS group were significantly higher than those in control group ( P

Objective To analyze the CT, especially HRCT appearance of localized organizing pneumonia. Methods The CT scans of nine patients with histologically proved localized organizing pneumonia were studied retrospectively. Results The size of the lesions in nine cases varied from 2 to 4 cm( average 2.5 cm). Eight lesions were located in the peripheral lung parenchyma near the pleural surface. The lesions were detected as round in four, anomaly in five. The margin of six lesions had inward bow indentation. Infiltrating lesions in surrounding structures were found in four cases. Conclusion The CT, especially HRCT appearance of localized organizing pneumonia shows some features that can make most of them to be differentiated from other lesions.

Plateau environment has a wide range of diurnal temperatures and thin air. The surgical shelter needs to resist the huge temperature shock and work in harsh environments, placing higher noise immunity requirements on the microenvironment temperature control system. The traditional microenvironment control of surgical treatment shelters mostly use instrument display and switch control, with a high failure rate and functional dispersion. We have designed a plateau microenvironment temperature control system with PLC as the control center and the touch screen as the Human Machine Interface so that real-time monitoring and control of temperature is achieved and the plateau temperature shock is resisted while the heater fuel ratio can be adjusted properly to adapt to plateau environment. This paper describes the control system hardware, software and algorithm design in detail.

Objective To observe the effects of chronic levodopa administration on cerebral dopamine transporter in healthy aged SD rats.Methods Twelve healthy aged SD rats was divided into three groups,which was respectively gavaged with high-dose of levodopa (150 mg/kg), low-dose of levodopa (50mg/kg) and NS everyday for four months. After levodopa was stopped for twenty-four hours, 0.2 ml of 99mTc-TRODAT-1 (800 ?Gi) was injected into the rats through vena caudalis. Three hours later, the rats were sacrificed and the wet weight of striatum, cerebral cortex, cerebella and brain stem was weighed. We measured the counts of radiation and calculated the numerical value of ID.Results The activity of ID in striatum was ( 0.764? 0.129) in high-dose group and ( 0.928? 0.145) in low-dose group. Compared with the control group ( 1.562? 0.289), the differences were significant ( P
