[Objective] To investigate the effects of Qianggu capsule plus alendronate on postmenopausal osteoporosis.[Methods]By random number generating method,120 patients were randomly divided into a treatment group with Qianggu capsule plus alendronate,control group A only with Qianggu capsule,and control group B only with alendronate.The pain of the patient before treatment,3 m and 6 m after treatment was assessed.At the same time,the bone mineral density (BMD) before and 6 months after treatment was recorded.[Results] There was significant difference before and after 3 m in the score of pain in three groups,but the difference in treatment group was higher than other two control groups.After 6 m,all the scores of pain in 3 groups had changed significantly compared to the ones before treatment,but the scores of pain in treatment group were lower than 2 control groups.The BMD of both vertebral and ward in treatment group after 6 months treatment was higher than before.[Conclusions]Qianggu capsule plus alendronate has definite therapeutic effects on postmenopausal osteoporosis.

Objective In recent years , SIT has gradually become the main way for the treatment of allergic rhinitis .To con-trast the clinical efficacy of specific immune therapy for one year and two years of allergic rhinitis and discuss the appropriate mainte -nance treatment time of subcutaneous immunotherapy with Dermatophagoides pteronyssinus . Methods Ninety-eight patients with al-lergic rhinitis to Dermatophagoides pteronyssinus were allocated to receive either treatment for one year (A group, n=46) or treatment for two years(B group, n=52).Nasal symptoms and medication scores of two groups were assessed to evaluate the clinical efficacy af -ter treatment respectively , and evaluate the quality of life of patients . Results There was no statistical significance in nasal symptom and medication scores between the two groups after one year treatment (7.00 ±1.08 vs 6.63 ±0.79, 1.50 ±0.51 vs 0.41 ±0.42, P>0.05).The quality of life in patients with decreased , but lack of statistical significance (345.00 ±31.89 vs 344.42 ±32.26, P>0.05).It presented statistical significance in nasal symptom and medication scores between the two groups after two years treatment (6.20 ±0.78 vs 4.29 ±0.64, 0.53 ±0.43 vs 0.21 ±0.34, P<0.05).The quality of life between patients also presented statistical significance (P<0.05). Conclusion Compared with A group, B group can significantly alleviate the symptoms of allergic rhinitis , so we think the optimal maintenance treatment time of specific immunotherapy for allergic rhinitis should be at least 2 years.

ObjectiveTo study the characteristics of wedge factor of enhanced dynamic wedge (EDW) on Varian 600C linear accelerator . MethodsEnhanced dynamic wedge factors (EDWFs) of different jaw settings were measured on a Varian 600C linear accelerator with FARMER 2570 dosimeter and 2571 0.6 ml Thimble ion chamber. At the same time,equations were used to compute EDWFs of symmetric and asymmetric fields and off axis points. The same measurements were carried out on 30 degree physical wedge in contrast to EDW. The accelerator's jaw position was described according to IEC radiotherapy equipment coordinate standard. Results The EDWFs of symmetric field decreased smoothly while the field size increased. Under the same field,EDWFs decreased as the wedge angle increased and the increasing extent became apparent when the field became larger. In off axis fields formed by the upper independent jaws,only the EDWFs of 60 degree had the tendency to increase when the field center moved toward the toe of the wedge,the rest gave the opposite results. The EDWFs of fixed points varied only by 0.5 percent when the fixed jaw remained at the same place and the moving jaw and lower jaws stayed at different positions. But the WF of 30 degree physical wedge increased by 2.9 percent when the lower jaw settings increased from 4 cm to 40 cm. The EDWFs derived from analytic equations for symmetric and asymmetric fields coincided well with measured results. But at off-axis points,the differences between calculated values and measured data were apparent. ConclusionsThe curve of EDWF versus field size is very smooth. The EDWF of fixed point only depends on the position of the stationary upper jaw,and is affected little by the moving upper jaw and lower jaws. The EDWFs of off axis fields are much more complex than those of physical wedge; it shouldn't be confused in clinical application. The conversion method of rectangular field to square field is of no use when EDW field is confronted. Analytic methods are highly conformal with the calculation of EDWFs of symmetric and asymmetric fields.

Objective To evaluate the efficacy of interventional therapy of occlusive lesion in iliaco- femoral arteries. Methods During Feb 2001 to Feb 2006, 42 patients (30 male and 12 female) with arterial occlusive lesions in iliac artery and/or femoral artery accepted interventional therapies. The interventional therapeutic process included local thrombolytic therapy through endoarterial catheter, artery recanalization by guide wire, pereutaneous transluminal angioplasty (PTA) and stent. After interventional operation, patients were administrated anticoagulant and antibiotics one week. Follow-up interval ranged 2 years. Wilcoxon test and t test were used for statistics. Results Immediate technical successful rate was 97.6% (41/42),the secondary technical success rate was 100.0% (42/42). The arterial occlusions were resolved successfully (local thrombolytic therapy in 26 cases, recanalization by guide wire in 31 cases, PTA in 33 cases and 60 stents in 31 cases). There were no severe complications (such as angiorrhexis, perforation) during interventional procedure. The symptoms of lower limb ischemia were palliated or vanished in all patients after interventional therapy. The ankle-brachnial index(ABI) of diseased extremities increased from pre-operation 0.34±0.14 to past-operation 0.65±0.10 (t=25.924, P <0.01 ). During the follow-up, 11/42 (26.2%) iliac or femoral artery (treated with local intra-arterial thrombolysis, PTA and stent) occurred restenosis. After PTA and stenting, the restenosis arteries became fluent successfully. The primary patency rate was 92.8% (39/42)and the secondary patency rate was 100.0% (42/42)1 year after the procedure. Two years after the procedure, the primary patency rate was 71.4% (30/42) and the secondary patency rate was 97.6% (41/42). Conclusions Interventional therapy (including local thrombolysis, recanalization, PTA and stent) is an effective and safe therapy for occlusive lesion in iliaco- femoral arteries.

Traditional sample entropy fails to quantify inherent long-range dependencies among real data. Multiscale sample entropy (MSE) can detect intrinsic correlations in data, but it is usually used in univariate data. To generalize this method for multichannel data, we introduced multivariate multiscale entropy into multiscale signals as a reflection of the nonlinear dynamic correlation. But traditional multivariate multiscale entropy has a large quantity of computation and costs a large period of time and space for more channel system, so that it can not reflect the correlation between variables timely and accurately. In this paper, therefore, an improved multivariate multiscale entropy embeds on all variables at the same time, instead of embedding on a single variable as in the traditional methods, to solve the memory overflow while the number of channels rise, and it is more suitable for the actual multivariate signal analysis. The method was tested in simulation data and Bonn epilepsy dataset. The simulation results showed that the proposed method had a good performance to distinguish correlation data. Bonn epilepsy dataset experiment also showed that the method had a better classification accuracy among the five data set, especially with an accuracy of 100% for data collection of Z and S.
