OBJECTIVETo investigate the therapeutic effect of Yiqi Huaju Recipe (YHR) combined with routine therapy on the blood pressure, the blood pressure variability and other cardiovascular risk factors in hypertension patients complicated with metabolic syndrome (MetS).

METHODSTotally 43 hypertension patients complicated with MetS were recruited in this study and randomly assigned to the treatment group (22 cases, treated with basic routine treatment +YHR) and the control group (21 cases, treated with basic routine treatment + placebo). The treatment course was 12 weeks. Detected were parameters such as 24-h ambulatory blood pressure monitoring (ABPM), body mass index (BMI), waist circumference (WC), waist to hip ratio (WHR), homeostatic model assessment for insulin resistance (HOMA-IR), fasting glycosylated hemoglobin A1c (HbA1c), fasting plasma glucose (FPG), 2 h postprandial plasma glucose (2 h PPG), fasting plasma insulin (FPI), serum lipid, etc.

RESULTSThe anthropometric parameters and plasma glucose levels (except HbAlc) were obviously lowered after treatment than before treatment in the treatment group (P < 0.01, P < 0.05). Besides, better effects were obtained in the WC, WHR, 2 h PPG, FPI and HOMA-IR (P < 0.05). The average blood pressure amplitude, the blood pressure variability, and blood pressure load at any time point were more obviously improved in the two groups after treatment than before treatment (P < 0.01, P < 0.05). Besides, partial indices were better in the treatment group than in the control group (P < 0.01, P < 0.05).

CONCLUSIONSYHR combined with routine therapy exhibited better effect on reducing the blood pressure amplitude, the blood pressure variability, and the blood pressure load in hypertension patients complicated with MetS. It could also effectively decrease the risk of other vascular disease.

Objective： The aim of this study was to evaluate the expression of E-cadherin,α -catenin,β -catenin,and γ -catenin in gastric carcinoma and dysplasia and to determine the relationship with tumorigenesis and biological behavior of gastric cancer. Methods： The expression of E-cadherin, α -catenin, β -catenin, and γ -catenin in 43 patients with gastric carcinoma and gastric biopsy specimens from 22 patients with dysplasia and 10 healthy controls were determined using immunohistochemistry. Results： Membranous staining was observed in control biopsy specimens for all components of the complex. Abnormal expressive rates of E-cadherin,α -catenin,β -catenin in gastric carcinomas (53.5％ ,55.8％ ,51.2％ ,respectively) were significantly higher than that in gastric mucosal dysplasials （ 22.7％ ,22.7％ , 18.2％ , respectively P<0.05） ,and the rates in advanced gastric carcinomas were also significantly higher than that in early gastric carcinoma（ P< 0.01, P< 0.05, P< 0.01,respectively） . Tumors with a decrease in E cadherin occurred significantly more frequently in undifferentiated gastric carcinoma (P< 0.05). There were higher abnormal expressive rates of E-cadherin and β  catenin in the patients with tumor infiltrating out of serosa and with lymph nodes metastasis （ P<0.01 or P< 0.05） . Up to 50.0％ of gastric dysplasials and 76.7％ of tumors stained abnormally for one or more components of the cadherin catenin complex (P< 0.05), and the lymph nodes metastasis rates for one or more components of the E cadherin complex was significantly higher than that for no one components of the E cadherin complex (P< 0.01). Conclusion： The decreased expression of E cadherin and part of the catenins correlate with tumor stage, poor differentiation, infiltrative tumor growth, and lymph nodes metastasis, which suggests that E cadherin complex play a critical role in the course of chang from gastric mucosal dysplasials to gastric carcinoma. Thus, study of all the components of E cadherin catenin complex may be more valuable than single component of the complex for the detection of patients with gastric carcinoma.

OBJECTIVESTo research the effects of supracondylar fractures of humerus treated by three different surgical methods.

METHODSThere were 103 patients with supracondylar fractures of humerus including 58 male and 45 female. The age was from 3 to 12 years old with the average of 7.4 years. To divide the cases into three groups by the operative approach in the humerus, the inside approach were in 37 cases (group A), the outside in 35 cases (group B) and the rear in 31 cases (group C). Comparing the reduction of the stretching and bending function of elbow joint and incidence of elbow varus.

RESULTSAll patients were followed-up for 1.5 to 8 years after operation with the average of 32 months. The reduction of stretching and bending function of elbow joint occurrenced in 6 cases in group A, 6 cases in group B and 25 cases in group C, the incidenc of group C were obvious more than group A and B (P < 0.01). The elbow varus occurred in 8 cases in group A, 17 cases in group B and 7 cases in group C, the incidence of group B were obviously more than group A and C (P < 0.05).

CONCLUSIONThere are different effects between three kinds of operative approaches in the humerus. The incidence of outside group is higher on the varus of elbow. The incidence of rear group is higher on the ability of elbow joint stretching and bending. The effect of inside group is sure on the operative approach in the humerus.

"Wise men could recognize similarities, but the fool only recognizes differences" in Su-wen, which expounded clinical thinking methods of Chinese medicine (CM). "To recognize similarities and differences simultaneously" is of important clinical significance in understanding the laws of diseases. CM pays much attention to recognize similarities, while modern medicine emphasizes the differences observed. In order to develop integrative medicine (IM), similarities recognition and differences identification must be combined together to innovate new thinking methods of IM.

Experiments were performed on Sprague Dawley rats with multibarrel microelectrode technique. The effects of acoustic response of A I cortex neurons produced by electrical stimulation of lateral amygdaloid nucleus (LA) and the influence of GABA were observed. Experimental results showed that iontophoretic administration of GABA caused a pronounced inhibition of the electrical activity of A-I neurons. Blockade of GABA(A) with bicuculline (BIC) facilitated the acoustic response. The acoustic response of A-I neurons was inhibited when the LA was stimulated. Iontophoretic application of GABA resulted in a similar inhibitory effect as that of LA stimulation. Blockade of GABA(A) with bicuculline reversed the inhibitory effect of LA stimulation on the acoustic response of A-I neurons. In contrast, application of strychnine, a glycine receptor antagonist, could not reverse the inhibitory effect of LA. Baclofen, a GABA(B) agonist, did not affect the acoustic response of the auditory neurons. These results indicate that GABA is the ultimate transmitter which mediates the LA stimulation-induced inhibition of the acoustic response of A-I neurons in rats, possibly via the GABA(A) receptor.
