Orthopedic Journal of China 2006;0(13):-
[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.

3.Discussion on Life Education of Traditional Chinese Medicine Based on Traditional Philosophy of Life
Chinese Medical Ethics 2017;30(2):191-194
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.

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 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

Aim To investigate the effects of berberine on extracellular matrix in rat glomerular mesangial cells cultured under high glucose and its possible mechanism.Methods Six groups were divided according to the different experimental conditions:① Normal glucose group (NG);② Mannitol group (Mannitol);③ High glucose group (HG);④ SB203580 treatment group (HG+SB203580);⑤ Berberine low dosagegroup (HG+BBR 30 ?mol?L-1);⑥ Berberine high dosage group (HG+BBR 90 ?mol?L-1). The phospho-p38MAPK,phospho-cAMP response element binding protein (CREB) and fibronectin were detected by Western blot analysis. Results Berberine obviously decreased protein expression of fibronectin compared with high glucose group. Phospho-p38MAPK and phospho-CREB level was significantly lowered compared with that of high glucose group. Conclusion Berberine can inhibit extracellular matrix accumulation including fibronectin via p38MAPK signal pathway in treatment of diabetic nephropathy.

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.

Objective To evaluate the efficacy of telephone follow-up on glycemic control in patients with diabetes mellitus. Methods Randomized clinical trials that assessed the effectiveness of telephone follow-up in patients with diabetes mellitus were selected in the databases of Cochrane library, JBI, PubMed, Medline, EMBASE, EBSCO, OVID, Springer, China National Knowledge Infrastructure, China Biomedical Literature Database, VIP , Wangfang Data. At the same time manual retrieval of relevant professional information to collect randomized clinical trials that met the inclusion criteria. The searching time was from database establishment to June 2016. RevMan5.2 software was used to analyze the data after quality assessment. Results A total of 12 randomized controlled trials were included in a total of 1905 patients. Meta-analyses showed that, compared with the conventional nursing group, the telephone follow-up could significantly reduce the level of glycosylated hemoglobin (weighted mean difference was-0.49, 95% confidence interval was-0.52--0.46, P<0.01), the level of fasting blood glucose (weighted mean difference was-0.99, 95% confidence interval was-1.16--0.83, P<0.01). Conclusions Telephone follow-up can improve blood glucose control in patients with diabetes, it is worth to be popularized in clinical practice.
