ABSTRACT
Objective To investigate the clinical effects and the degree of satisfaction of areola margin small incision and conventional incision in the treatment of patients with benign tumor of mammary glands. Methods 338 patients were selected and randomly divided into the observation group and the control group according to the digital table,169 patients in each group. The clinical effects and the degree of satisfaction of the patients were compared. Results Compared with the control group, the operation time was slightly longer in the observation group[(26. 2 ± 4. 8) min vs. (24. 5 ± 3. 7) min,t =13. 178,P =0. 000];The incidence rate of postoperative complications was significantly reduced (2. 37% vs. 34. 55%,χ2 =57. 911,P=0. 000);The scar score wassignificantlylower[(1.11±0.47)pointsvs.(4.14±0.45)points,t= -60.387,P=0.000];Thepostoperative satisfaction rate was significantly higher (98. 82% vs. 62. 13%,χ2 =72. 379,P =0. 000). Conclusion Areola margin small incision has high degree of satisfaction and small scar,provides safe and reliable effect in treatment of benign tumor of mammary glands. This method can be suitable for popularization and application in clinic.

ABSTRACT
Objective To observe the effect of serum containing Qiangjijianli oral liquid in-vitro proliferation of rat mesenchymal stem cells (MSCs). Methods Rat mesenchymal stem cells dissociated from the bone marrow by density gradient method were cultured. MSCs were identified by marking of bromodeoxyuridine (Brdu) and staining of CD44, CD45. Experimental group was cultivated with serum containing Qiangjijianli oral liquid and control group with blank serum. Optical absorption value of MSCs was stained by methyl thiazolyl tetrazolium (MTT). Results Serum containing Qiangjijianli oral liquid at different concentrations could promote the proliferation of MSCs, the difference being significant in comparison with the control group (P

ABSTRACT
[Objective] To explore the relationship between TCM syndrome patterns and physicochemical parameters of chronic obstructive pulmonary disease (COPD). [Methods] Five hundred hospitalized cases of COPD were investigated. The correlation of TCM syndrome patterns with pulmonary function, blood analysis and biochemical indexes were assayed by logistic forward regression analysis and linear multiple regression analysis, and then the above indexes were analyzed by independent- samples t test. [Results] Five equations were obtained by logistic regression. Positive correlation was found between the number of white blood cells (WBC) and the pattern of phlegm-heat blocking lung, hemoglobin (HGB) level and the pattern of yang deficiency with fluid retention, as well as red cell distribution width (RDW) and the pattern of kidney deficiency. Maximal expiratory flow rate in residual 75 % vital capacity ( MEF75), peak of expiratory flow (PEF) and mean corpuscular hemoglobin (MCH) were negatively correlated with the pattern of yang deficiency with fluid retention. Maximal expiratory flow rate in residual 25% vital capacity (MEF25) and granulocyte percentage (GP) were also negatively correlated with the pattern of spleen deficiency. So did potassium ions (K+ ) level and the pattern of kidney deficiency, t test showed the same results. [Conclusion] The above indexes have great value for TCM syndrome differentiation of COPD.
