UNLABELLEDOBJECTIVE; To evaluate the efficacy and safety of Jiangtang Xiaozhi Capsule (JTXZC) in treating type 2 diabetes mellitus (T2DM) of qi-yin deficiency phlegm-stasis inter-obstruction syndrome (QYDPSIOS), and to observe its effect on inflammatory factors and fibrinolytic factors.

METHODSBy adopting a randomization grouping, parallel control, and prospective study, 73 T2DM patients of QYDPSIOS were assigned to two groups by random digit table, the Pioglitazone Tablet group (36 cases, as the control) and the JTXZC group (37 cases). All patients maintained their basic therapies and lifestyle as previous after recruitment. Patients in the JTXZC group took JTXZC, 4 pills each time, three times per day, while those in control group took Pioglitazone Tablet, 15 mg each time, once daily. The therapeutic course for all was 8 weeks. The body weight (BW), the height, body mass index (BMI), waist circumference (WC), hip circumference, waist-to-hip ratio (WHR), and scoring of Chinese medicine (TCM) symptoms were observed. Levels of fasting blood glucose (FBG), 2 h postprandial blood glucose (2 h PBG), glycated hemoglobin (HbA1c), tumor necrosis factor alpha (TNF-alpha), nuclear factor kappaB (NF-kappaB), and plasminogen activator inhibitor 1 (PAL-1) were detected. The safety indices such as liver and renal functions and adverse reactions were also observed.

RESULTSCompared with before treatment, BW, BMI, HbA1c, and PBG were obviously lower after 8-week treatment than before treatment in the JTXZC group (P < 0.05). There was no statistical difference in post-treatment BW, BMI, HbA1c, or 2 h PBG between the two groups (P < 0.05). Compared with before treatment, levels of TNF-alpha and PAI-1 were lowered after 8 weeks of treatment in both groups (P < 0.01). The level of NF-kappaB was obviously lowered after 8 weeks of treatment in the control groups (P < 0.05), but it also decreased in the JTXZC group with no statistical difference. The scorings of CM symptoms were somewhat improved after treatment in the two groups (P < 0.01). Besides, better effects were obtained in the JTXZC group (P < 0.05). No severe adverse event occurred in either group during the whole therapeutic course.

CONCLUSIONSJTXZC showed similar therapeutic effect to pioglitazone. Both of them could effectively improve patients' clinical symptoms, the inflammation and fibrinolytic activities in different pathways, with no severe adverse reaction.

Objective To discuss the technical specifications of current high-frequency electrotome detection,to avoid the hidden danger of high-frequency electrotome power detectors,and to measure the leakage current of different kinds of highfrequency electrotome accurately.Methods The power and leakage current of the high frequency electrotome were measured by FLUCK QA-ES Ⅱ high frequency electrotome analyzer.The safety of the two methods was compared before and after the improvement of the power measurement.Four parameters of leakage current were repeatedly measured with the ways of high frequency earthing and high frequency isolation respectively.The maximum measurement of leakage current was recorded.Results The improved connection method was safe in the power measurement.For the high-frequency electrotome in the model of high frequency earthing,the values of leakage current were restrained within the range of error with two ways of monopolar loading operation electrode and neutral electrode.For the high-frequency electrotome in the model of high frequency isolation,the values of leakage current were limited within the range of error withtwo ways of monopolar empty operation electrode and neutral electrode.Conclusion The improved high-frequency electrotome power detection method is safe for detectors.The data obtained from the leakage current detection method using the national standard correction method reflect the actual state of the high-frequency electrotome,when the electrotome with earth as the reference is used to detect the leakage current with loading or the insulated electrotome is applied to measuring the leakage current with no loading.

Objective To investigate the MRI and echocardiography manifestations of noncompaction of ventricular myocardium(NVM)and assess the role of MRI in the diagnosis of NVM by comparing it with echocardiography.Methods Fourteen cases of NVM diagnosed by echocardiography were examined with MRI,including scanning of black-blood sequences,double inversion recovery fast spin echo (DIRFSE)and triple inversion recovery fast spin echo(TIRFSE),and white blood sequence:fast imaging employ steady state acquisition(FIESTA).Scanning plane includes short axis view,four-chamber view and long axis view.Results Both MRI and echocardiography displayed involvement of left ventricles in thirteen cases and involvement of double ventricles in one case.Apexes of heart and the intermedius are commonly affected.MRI showed 54 segments and echocardiography showed 53 segments affected,and there is no significant difference between the capability of MRI and echocardiography(P=1.000).The affected myocardium consisted of two layers:subendoeardial noncompacted myocardium and epicardial compacted myocardium,and the ratio measurement of N/C by MRI was 3.37?0.89 and it was 3.19?0.82 by echocardiography.Noncompacted myocardium was characterized by prominent and excessive myocardial trabeculations and deep intratrabecular recesses,in which the blood flow was communicated with the ventricle.One case was complicated with ventricular aneurysm,and coronary arteriography was performed with unremarkable findings.One case underwent heart transplantation because of progressive heart failure, Gross findings demonstrated prominent muscular trabeculations with deep intratrabecular recesses,which coincided well with MRI findings.Conclusion The MRI manifestation of NVM is characteristic,and MRI with multiple series and planes is helpful in the diagnose of NVM.Compared with echoeardiography,MRI could display the pathological cardiac muscle more clearly,because of its high soft-tissue resolution and spatial resolution.

OBJECTIVETo investigate the effects of polysaccharide 2-1 from Gastrodia elata (PGE2-1) on blood coagulation and thrombosis.

METHODClotting time (CT) and bleeding time (BT) of mice were measured by glass method and tail-cutting method. Bleeding capacity (A540) was measured by cutting tail in 5 min. Plama recalcificatic time (RT) were measured in mice. Platelet aggregation was caused by adenosine diphosphate (ADP). Activated partial thromboplastin time (APTT), prothrombin time (PT), and thrombin time (TT) were measured by reagent boxes. During thrombosis in vitro, their lengths, wet and dry weights were measured by instrument; wet weights of arteriovenous experimental thrombosis were measured and the impressive rates were analyzed.

RESULTCT and BT of groups PGE2-1 (60, 120 mg x kg(-1)) were remarkably prolonged, and bleeding capacity (A540) were significantly increased (P < 0.05 or P < 0.01). RT of groups PGE2-1 (30, 60, 120 mg x kg(-1)) were remarkably prolonged, and platelet aggregation (PAG) were inhibited (P < 0.05 or P < 0.01). Human serous TT and APTT of groups PGE2-1 (10, 20, 40 mg x mL(-1)) were remarkably prolonged (P < 0.05 or P < 0.01), but the difference of effect on PT had no statistic significance. PGE2-1 (30, 60, 120 mg x kg(-1)) could make the mice obviously eliminate thrombus symptom and reduce the time of restoring independent activity (P < 0.05 or P < 0.01); thrombosis in vitro: Lengths, wet and dry weights of groups PGE2-1 (30, 60, 120 mg x kg(-1)) were significantly decreased (P < 0.05 or P < 0.01); wet weights of arteriovenous experimental thrombosis were dramatically decreased (P < 0.01), and impressive rates were respectively 32.5%, 49.0% and 61.5%.

CONCLUSIONPGE2-1 has remarkable effects of anticoagulation and antithrombosis, so it may be the main component of the isolation from G. elata in the field of antithrombosis.

OBJECTIVETo evaluate the efficacy and safety of Jiangtang Xiaozhi Capsule (JTXZC) in treating type 2 diabetes mellitus (T2DM) patients of qi-yin deficiency and inter-obstruction between phlegm and stasis.

METHODSAdopting prospective, randomized, controlled trial design, 73 T2DM patients of qi-yin deficiency and inter-obstruction between phlegm and stasis syndrome, were randomly assigned to two groups, the pioglitazone tablet group (36 cases) and the JTXZC group (37 cases). The therapeutic course for all was 8 weeks. The body weight, height, body mass index (BMI), waistline (WC), hipline, waist-to-hip ratio (WHR), and scoring for Chinese medicine (CM) symptoms assessment were observed. The fasting blood glucose (FBG), 2-h postprandial blood glucose (PBG), glycated hemoglobin (HbA1c), plasma total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), plasma insulin (FINS) were detected. The HOMA-IR was also calculated. The safety indices such as liver and renal functions, adverse reactions were also observed.

RESULTSThe levels of HbA1c were lowered after treatment in the two groups after 8 weeks of treatment, showing statistical difference when compared with before treatment (-0.59% +/- 1.99% and -0.27% +/- 2.73%, P < 0.05). The PBG level also decreased with statistical difference (-1.71 +/- 2.52 mmol/L and -0.72 +/- 4.17 mmol/L, P < 0.05), but there was no statistical difference between the two groups. The body weight, BMI, TG obviously decreased (P < 0.05). The CM symptoms efficacy and CM symptom scoring were significantly reduced in the two groups (P < 0.01). Besides, better effects were shown in the JTXZC group (P < 0.05). No severe adverse event occurred in either group during the therapeutic course. There was no statistical difference in the incidence of adverse events (P > 0.05).

CONCLUSIONSJTXZC showed similar therapeutic effects to pioglitazone. They both could effectively im- prove clinical symptoms with no severe adverse reaction.

OBJECTIVETo investigate the effect of pulsed electromagnetic fields (PEMs) on inducing osteoclastic like cell (OLC) formation changes and apoptosis in ovariectomized (OVX) rats bone marrow culture in vitro.

METHODSThirty healthy three-month-old female Wistar rats were either sham-operated (Sham) or ovariectomized (OVX) and randomly divided into three groups: group A (OVX + PEMs, 18 rats), group B (OVX, 6 rats) and group C (Sham, 6 rats); group A was again randomly divided into three groups: A1, A2, A3. The frequencies adopted were 1.5, 2, 75 Hz and 30 minutes for once a day. All rats were fed with normal diet for 3 months, then the bone marrow of all rats were cultured, 2 days later, group A cells (including group A1, A2, A3) were collected and exposed to different frequencies PEMs for 2 weeks (30 min/day). In order to observe the changes of osteoclasts and count their numbers, cells were taken for Wright Giemsa staining, tartrate-resistance acid phosphatase (TRAP) staining and Hoechst 33258 staining.

RESULTSTRAP staining results indicated the number of OLC in group C was the least, then was group A2, A3, A1, B. The number of OLC in group B was remarkably increased (P < 0.01; vs group C, A2). The number of OLC in group B was significantly increased (P < 0.05; vs group A1, A3). Hoechst 33258 staining results indicated the number of apoptosis of OLC in group C was more than other groups, which of group C, A2 was significantly increased (P < 0.05; vs group B).

CONCLUSIONPEMs had decreased the formation of OLC and increased the number of apoptosis of OLC in ovariectomized (OVX) rats bone marrow culture in vitro, the effects of 2 Hz was the best. PEMs would be a new way of osteoporosis therapy.
