[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.

OBJECTIVE:To establish a simple individualized dosage regimen of multiple oral dosing of Theophyllin. METHODS:Based on pharmacokinetic parameters,Excel function was used to design the dosage regimen of multiple oral dosing extravascular administration of one-compartment model with Theophylline as an example. RESULTS:The following parameters such as plasma drug concentration at any time (t) since administration of Theophylline,peak time,maximum steady plasma-drug concentration,minimum steady plasma-drug concentration,accumulation coefficient,fluctuation percentage,fluctuation amplitude,and dosage for children and the old could be obtained and the concentration-time curves were able to be drawn from the input data including physical and pathological parameters,dosage (X0) of Theophylline,interval ?,absorption rate constant (Ka),drug clearance rate (CL),absorption fraction (F) and apparent volume of distribution (Vd). CONCLUSION:The method adopted in our study is simple,reliable and intuitive,and it is applicable for the design of the individualized dosage regimen of Theophyllin.

OBJECTIVETo investigate molding technology of total alkaloids from Sophora alopecuroides freeze-dried powders and observe its inhibition effects on liver transplantation tumor in mice.

METHODWith color, clarity, water-soluble and formability as indexes, single factor tests were adopted to screen type and amount of filler, the concentration of total alkaloids in drug liquid, pH in order to determine optimum prescription of total alkaloids from S. alopecuroides freeze-dried powders, the lowest melting point was determined and freeze drying curve was drafted. Mice hepatoma H22 ascites tumor strain was sterile inoculated in right axillary subcutaneous of mice, and antitumor effect of total alkaloids from S. alopecuroides freeze-dried powders on liver transplantation tumor H22 in mice.

RESULTWhen selected 80 g x L(-1) as mannitol as filler, the concentration of total alkaloids in drug liquid was 25 g x L(-1) and pH 6.5-7.5, freeze-dried effect was optimum with fast reconstitute speed. Average inhibition rate of the big (120 mg x kg(-1)) and medium (60 mg x kg(-1)) dose group of total alkaloids from S. alopecuroides freeze-dried powders on liver transplantation tumor H22 in mice were 56.08% and 35.49%, respectively.

CONCLUSIONPreparation technology was reasonable, reproducible and stable, total alkaloids from S. alopecuroides freeze-dried powders had significant antitumor effect and showed a dose-effect relationship.

The present study is to elucidate the mechanisms underlying Gleevec-induced apoptosis of chronic myeloid leukemia (CML) K562 cells in vitro. The apoptotic cell death and cell cycle distribution after Gleevec treatment and the effect of PDCD4 siRNA on Gleevec-induced apoptosis of K562 cells were analyzed by flow cytometry. The effect of Gleevec on p-Crkl, caspase-3, PARP and PDCD4 protein levels, and the knockdown efficacy of PDCD4 siRNA were detected by Western blotting. The results showed that Gleevec dramatically suppressed the phosphorylation level of Crkl in a dose-dependent manner and induced significant apoptosis and G0/G1 cell cycle arrest of K562 cells in time- and dose-dependent manners. In addition, Gleevec activated caspase-3 and its downstream substrates PARP, and the caspase pan inhibitor Z-VAD-FMK (50 micromol x L(-1)) markedly reduced Gleevec-induced apoptosis from 47.97% +/- 10.56% to 31.05% +/- 9.206% (P < 0.05). Moreover, Gleevec significantly increased the protein expression of programmed cell death 4 (PDCD4). PDCD4 knockdown by siRNA reduced Gleevec-induced apoptosis from 46.97% +/- 14.32% to 42.8% +/- 11.43%. In summary, Gleevec induced apoptosis in K562 cells via caspase-3 activation.

Objective To investigate the clinicopathological features of tubular aggregate myopathy.Methods Eight patients as experimental group were diagnosed with tubular aggregate myopathy in Department of Neurology,People' s Liberation Army General Hospital,between March 2000 and March 2013.The data were retrospectively analyzed.Enzyme histochemical techniques and electron microscopy were taken to observe the muscle structures.Results The detection rate of tubular aggregate was 0.374％ (8/2 137).All of the 8 patients with tubular aggregate myopathy were male.Five patients presented with episodes of muscle weakness,while 3 patients presented chronic progressive muscle weakness.The main clinical features of all patients were muscle weakness.The creatine kinase level was mildly elevated in 4 patients,while it was normal in the other 4 patients.Electromyogram showed myogenic damage in 5 patients and normal in 3 patients.All of the 8 patients denied family history.By light microscopy,hematoxylin-eosin staining showed that tubular aggregates were multiple basophilic subsarcolemmal substance.Tubular aggregate stained red with modified Gomori trichrome stain,reacted intensely for nicotinamide adenine dinucleotidetetrazolium reductase,and remained unstained on oil red O,periodic acid Schiff,sudan black B,acid phosphatas,adenosine triphosphatase.By electron microscopy,tubular aggregates were densely packed tubules predominantly in the subsarcolemmal region.Conclusion Enzyme histochemical staining and electron microscopy show special features of tubular aggregate myopathy,are the critical techniques for the diagnosis of the disease.

Objective To observe the effects of Chinese herbal compounds (alkaloid of Coptidis Rhizoma 40%, total saponin of panax notoginseng 35%, and polysaccharide of Ophiopogonis Radix 25%) on levels of blood glucose, fructosamine, and insulin of diabetic rats, and explore mechanism of action.Methods Ten rats were randomly chosen as blank control group, and other rats were used to establish diabetic rat models by STZ intraperitoneal injection. Successfully molding rats were randomly divided into Chinese herbal compounds high, medium, low dose groups, metformin group, and model group, 10 rats in each group. Each rat received gavage for continuous 4 weeks. Then rat blood was collected by cutting head and taking caudal vein. FBG was detected by glucose oxidase method;insulin level was detected by radio-immunity double antibody method;fructosamine content was detected by fructosamine method.Results Compared with the blank control group, model group the levels of FBG, froctosamine content increased, while fasting insulin level were lower after 4 weeks'medication. Compared with the model group, the levels of FBG, froctosamine content in Chinese herbal compounds high and medium dose groups and metformin group were lower, while fasting insulin level increased after 4 weeks'medication (P<0.05).Conclusion TCM herbal compounds can increased the basic insulin level by decreasing the contents of FBG and fructosamine.
