Objective To evaluate the relationship between carotid artery plagues and the clinical risk factors in patients with diabetes mellitus type 2 by observing the ultrasonic characteristics of carotid atherosclerosis plagues.Methods The ultrasound results of carotid arteries in 665 patients with diabetes mellitus type 2 from January 2009 to December 2011 in Beijing Amery General Hospital were retrospectively analyzed.The location and quantity of carotid atherosclerotic plaques were observed .The relationship between the occurrence and risk factors of diabetes such as hypertension ,family history of diabetes and age were analyzed.Single factor and multi-factor analysis were applied for the related risk factors .Results The ultrasonography showed 405 cases of carotid artery plaques.Most carotid artery plaques were located in the posterior wall of carotid sinus and were hyperechoic ,hypoechoic or isoechoic.The single factor analysis showed hypertension,family history of diabetes and age are risk factors of carotid atherosclerosis (χ2 =42.322,9.682 and 140.658,all P<0.01).Multi-factor logistic regression analysis showed age was an independent risk factor of carotid atherosclerosis in patients with diabetes mellitus type 2.The risk factors scores of patients who were less than 45 years,45-65 years and over 65 years of age were (3.50 ±1.16)scores,(3.46 ±0. 92)scores and (3.21 ±0.88)scores,and the difference was statistically significant (F=5.781,P<0.001). There were significant differences between risk factors scores of different age groups ( t =2.084,2.002, 3.786,3.474,2.877 and 2.504,all P<0.05).In patients more than 65 years of age,the risk of atherosclerosis plaques is 28.732 times higher than that of patients less than 45 years of age.After controlling the age factor,the possibility of atherosclerosis plaque increased 1.201 times for each additional one point of score. Conclusions Most carotid artery plaques in patients with diabetes mellitus type 2 are located in the posterior wall of carotid sinus and are hyperechoic ,hypoechoic or isoechoic.Age is an independent risk factor for the formation of carotid plaque.Patients more than 45 years of age should undergo early intervention to avoid the occurrence of major vascular complications .

OBJECTIVETo compare the clinical therapeutic effects between ozone and triamcinolone acetonide for the treatment of mild meniscal injury.

METHODSFrom January 2008 to December 2012, 119 patients with meniscal injury diagnosed as type I or II by MRI were divided into three groups. In the triamcinolone acetonide (A) group, there were 38 males and 2 females, with an average age of (25.34 +/- 6.34) years old, ranging from 18 to 48 years old; 36 patients had single knee injuries, 4 patients had double knee injuries and 44 knees with joint effusion. In the ozone (B) group,there were 37 males and 2 females, with an average age of (26.98 +/- 7.20) years old, ranging from 19 to 50 years old; 33 patients had single knee injuries, 6 patiens had double knees injuries and 40 knees with joint effusion. In the combination of ozone and triamcinolone acetonide (C) group, there were 37 males and 3 females,with an average age of (26.44 +/- 6.38) years old, ranging from 18 to 47 years old; 33 patients had single knee injuries, 7 patients had double knees injuries and 39 knees with joint effusion. The patients were treated with injection of 3 mg triamcinolone acetonide alone, 30 ml (30 microg/ml) ozone alone, or both two drugs respectively in knee joint cavity. All the treatment methods were carried out weekly and 4 times injections were required for a treatment course. Knee joint function was evaluated by Lysholm scale and knee joint effusion was examined by MRI before and after treatment.

RESULTSThe scale of knee joint function was 35.68 +/- 4.15 and 65.55 +/- 7.66 in group A, 36.35 +/- 6.83 and 74.39 +/- 8.47 in group B, 36.62 +/- 6.03 and 95.47 +/- 4.78 in group C before and after treatment. Compared with that before treatment, the total scale of knee joint function improved after treatment in every group. The total scale of group C was better than that of the other groups after the treatment,but there was no significant difference between group A and group B. The effective rate of these drugson joint effusion was 68.18% in group A, 62.5% in group B and 87.18% in group C. The effect of co-injection on joint effusion in group C was significantly better than that of triamcinolone acetonide or ozone alone, but the difference between group A and group B was not significant.

CONCLUSIONOzone and triamcinolone acetonide are effective in the treatment of mild meniscal injury, which can relieve symptoms and promote the recovery of joint function. Campared with the single injection, the combination of ozone and triamcinolone acetonide is better.

Rutaecarpine (Rut) is a type of indole quinazoline alkaloid exracted from Ruticarpum. Studies showed that Rut has a wide range of pharmacological effects, such as anti-hypertension, anticancer, anti-inflammation, anti-thrombus formation. Currently, many scholars are committed to developing it into a new antihypertensive and anti-inflammatory drug with all new mechanisms. But studies found that Rut is a highly fat-soluble drug with low water and oil solubility. Its high insolubility is the main obstacle in its oral absorption and application, which greatly reduced its bioavailability. Therefore, hydroxypropyl-beta-cyclodextrin (HP-beta-CD) was used as the inclusion material to prepare Rut-HP-beta-CD inclusion complex in this experiment, in order to increase its water solubility and bioavailability. In this experiment, the inclusion complex was prepared by the stirring-freeze-dry method. The preparation process was optimized by the orthogonal test, with the inclusion rate as the index, and molar ratio between host and guest molecules, inclusion temperature, time and stirring speed as the impacting factors. Moreover, the inclusion complex was verified by detecting the apparent solubility, thin layer chromatography, microscopic identification, melting point detection and dissolution study. The results showed that under the conditions of the molar ratio between Rut and HP-beta-CD of 1: 1, temperature at 60 degrees C, inclusion time of 4h and stirring speed at 600 r x min(-1), the inclusion rate of Rut-HP-beta-CD reached 91.04%. Therefore, the preparation process of Rut-HP-beta-CD inclusion under the optimum conditions is simple and feasible, with a highest inclusion rate and reproducibility, and could significantly improve Rut's solubility and bioavailability, and provide a reliable experimental basis for its clinical application.

OBJECTIVETo explore methods of treating middle and distal tibia nonunion with the treatment of advanced bone graft combined with locking compression plate.

METHODSFrom January 2011 to December 2012, 12 patients with middle and distal tibia nonunion were treated with advanced bone graft combined with locking compression plate. Among patients, there were 8 males and 4 females aged from 20 to 69 with an average of 47 years old. The time from first injuries to bone nonunion was from 9 months to 5 years, avergaed 19 months. Four cases were treated with external fixation, 6 cases were treated with plate fixation, 2 cases of 12 patients occurred broken of plate and nail. Eleven patients were non-infective bone nonunion and 1 patient was infective bone nonunion. Preoperative X-ray and CT showed all patients had sequestration and formation of ossified bone with different degrees. Operative time, blood loss, wound healing were observed, fracture healing time was evaluated by postoperative X-ray. Johner-Wruhs scoring standards was used to evaluate ankle joint function after operation at 10 months.

RESULTSOperative time ranged from 90 to 185 min with an average of (125.00±20.15) min; blood loss ranged from 225 to 750 ml with an average of (415.00±120.00) ml. All patients were followed up from 10 months to 2.5 years with an average of 1.5 years. Postoperative X-ray showed bone union was formed around fracture after operation at 4 months in all patients, 3 cases obtained bone healing within 6 months after operation, 9 cases obtained from 8 to 12 months. No infection, injury of nerve and vessles, and broken of plate and nail were ocurred. According to Johner-Wruhs scoring at 10 months after operation, 10 cases obtained excellent results, 1 good and 1 moderate.

CONCLUSIONAdvanced bone graft combined with locking compression plate, which can build fracture multi-point supporting based on full compression of bone nonunion to get effective fixation, is an effective method in treating middle and distal tibia nonunion.

Through searching domestic and foreign medical journals in CNKI, Wanfang database, VIP database and Pubmed database from January of 2003 to November of 2013, 39 articles regarding musical electroacupuncture (MEA) were analyzed. The result showed that MEA was clinically used to treat neurological and psychotic disorders; because it was combined with musical therapy and overcame the acupuncture tolerability, and MEA was superior to traditional electroacupuncture. However, problems such as low research efficiency and the mechanism of MEA superiority and the musical specificity not being revealed by research design still exist. In future, large-sample multi-center RCT researches should be performed to clarify MEA clinical efficacy. With modern science and technology and optimized study design, guided by five-element theory of TCM, researches on different musical elements and characteristics of musical pulse current as well as MEA's correlation with meridians and organs should be studied, so as to make a further exploration on MEA mechanisms and broaden the range of its clinical application.

Objective:To study the effects of Tongxinluo,a traditional Chinese medicine,on the proliferation of peripheral blood-derived endothelial progenitor cells(EPCs)in vitro.Methods:The Tongxinluo solution was prepared through ultrasonication according to the pervious literature.The mononuclear cells(MNCs)were isolated from the peripheral blood with Ficoll by density gradient centrifugation.MNCs were suspended in Medium 199 containing 20% fetal blood serum(FBS)and vascular endothelial growth factor(VEGF).After cultured for 7 d,the attached cells were characterized by Di-LDL uptaking and FITC-lectin binding by laser confocal microscope,and further identified through detection of CD34 and CD133 expression by flow cytometry.Then the cultured EPCs were incubated with Tongxinluo at a series of concentrations(0,50,100,200,500, 750,1000?g/ml)for different durations(0,6,12,24 and 36 h).The cell morphology was observed and cell proliferation was determined by MTT assay.Results:Incubation with different concentrations of Tongxinluo increased the proliferative ability of EPCs.Tongxinluo at 500?g/ml had the most prominent effect on proliferation and the effect increased as time went by and reached peak at 36 h(growth rate 54.18%,P

Pestalotiopsis photiniae is one of the predominant pathogens of strawberry root rot disease. Based on preliminary research, it was proved that crude toxins were main pathogenic substances of the pathogen. For further investigation and utilization of toxins produced by this fungus, conditions of producing toxins were analyzed with the leaf disk method in this experiment. The result showed that pH values, cultural time, vibration, and tested temperatures obviously affected the production of toxins, except for light treatment. The most suitable culture conditions for the toxin production were pH 6.2, 25?C, darkness and stillness, for 5 d～7 d. Besides, it was discovered that crude toxins could significantly inhibit seed germination and elongation growth of roots or shoots for maize, rye and mung bean.

OBJECTIVETo evaluate the efficacy and safety of Xinmailong Injection (XI) in treatment of chronic heart failure (CHF) patients with qi-yang deficiency and blood stasis resistance syndrome (QY-DBSRS).

METHODSTotally 238 CHF patients with QYDBSRS were assigned to the treatment group (118 cases) and the control group (120 cases) by randomized, double-blind, placebo parallel controlled method. Patients in the treatment group received routine therapy and XI (100 mg/2 mL, by dripping at 5 mg/kg, twice per day for 5 consecutive days), while those in the control group received routine therapy and XI mimetic agent (100 mg/2 mL, by dripping at 5 mg/kg, twice per day for 5 consecutive days). The heart function classification of New York Heart Association (NYHA), 6-min walking distance, left ventricular ejection fraction (LVEF), scores for Chinese medical symptoms were observed before and after treatment, and safety assessed.

RESULTSTotally 235 patients actually entered full analysis set (FAS), including 120 cases in the control group and 115 cases in the treatment group. The total effective rate of heart function, 6-min walking distance and increased post-pre-treatment distance in the experimental group were superior to those of the control group with statistical difference (all P < 0.05). Compared with the control group, increased value of post-pre-treatment LVEF, the total effective rate of Chinese medical syndrome efficacy, scores for Chinese medical symptoms and decreased post-pre-treatment value of Chinese medical syndrome scores were obviously improved (all P < 0.05). There was no significant difference in the incidence of adverse events between the two groups (P > 0.05).
