OBJECTIVE:To observe clinical efficacy and safety of Xinmailong injection combined with trimetazidine in the treatment of chronic heart failure of coronary heart disease(CHD)(Qi Yang deficiency ). METHODS:A total of 80 patients with Qi Yang deficiency chronic heart failure of CHD were selected from our hospital during Jan. 2011-Dec. 2105 were divided into ob-servation group and control group according to random number table,with 40 cases in each group. Both groups received routine treatment. Control group was additionally given Trimetazidine dihydrochloride tablets 20 mg,tid,for consecutive 6 months,on the basis of routine treatment. Observation group was additionally given Xinmailong injection 5 mg/kg added into 0.9％ Sodium chlo-ride injection 500 mL,ivgtt,at speed of 30 drops/min,bid,medication interval>6 h,for consecutive 5 days,on the basis of con-trol group. Efficacies of cardiac function improvement,TCM symptom efficacies as well as LVEF before and after treatment were observed in 2 groups. The occurrence of ADR was compared between 2 groups. RESULTS:Total response rates of cardiac function and TCM symptom were 90.00％ and 95.00％ in observation group,which were significantly higher than 62.50％ and 55.00％ of control group,with statistical significance (P<0.05). Before treatment,there was no statistical significance in LVEF between 2 groups (P>0.05). After treatment,LEVF levels of 2 groups were increased significantly,and the observation group was signifi-cantly higher than the control group,with statistical significance(P<0.05). There was no statistical significance in the incidence of ADR between 2 groups (P>0.05). CONCLUSIONS:Xinmailong injection combined with trimetazidine in the treatment of Qi Yang deficiency chronic heart failure of CHD show significant therapeutic efficacy and improve LEVF level with good safety.

The growth of P. cruentum when added organic carbon source, organic nitrogen source and group B vitamin into medium were investigated in the present work. Results showed that glucose promoted growth rate observably. When addedZ% (W/V)glucose into the medium, the growth rate was doubled and biomass increased 92.6%to that of control after incubated 10 days . organic nitrogen source restrained the growth or harmed to P. cruentum. Vitamin Be and B12 also promoted the growth rate.

Objective To explore an effective surgical treatment to the keloid of mons pubis.Methods From March 2008 to January 2015,local flap and adjacent flap (including ilioinguinal flap and rectus abdominal musculocutaneous flap) were performed,and used to repair the defect after surgical removal of the keloid in 25 patients,and all the patients were received postoperative local radiotherapy,and then chi square test was applied to evaluate the effect in the six aspects,including perineal form,skin color,pubic hair distribution,satisfactory effect,skin texture and sense.Results The local flap group was better than the adjacent flap group in perineal form,skin color,pubic hair distribution,satisfactory effect,but there was no significant difference in skin texture and sense.Conclusions For the keloid of mons pubis,the first choice is local flap graft,which can maintain the normal mons pubis formation as most as possible,while the wound is so large that the local flap cannot work,and therefore the vascular pedicle axial flap should be used.

Objective To study the effect of hyperbaric oxygen preconditioning management on the expression of MMP-2,MMP-9 and Cx43 in a rat abdominal skin flap model of ischemia-reperfusion injury.Methods Eighteen male adult SD rats,weight ranged from 220-250 g,were randomly divided into three groups:sham group (SH),ischemia-reperfusion group (IR) and hyperbaric oxygen preconditioning group (HBO).All the rats in HBO group received hyperbaric oxygen treatment twice each day,apart 12 hours,during the last three days before operation.Abdominal skin flap with superficial epigastric artery as pedicle was established.In HBO and IR group,3 hours of ischemia was performed.On the 3rd postoperative day,samples were taken to assess the expression of MMP-9,MMP-2 and Cx43 by immunohistochemical staining and Western blot.Results Compared with IR group,the expression of Cx43 was significantly increased (IR 15.03±3.66;HBO 36.01±4.12) and the ex pression of MMP-9 and MMP-2 was decreased (MMP 2:IR 12.01±1.23;HBO 5.98±1.48;MMP9:IR 16.77±2.01;HBO 11.48±1.77).Conclusions Hyperbaric oxygen preconditioning for the rat abdominal skin flap model of ischemia-reperfusion injury has inhibitory effect on the expression of MMP-9 and MMP-2,and stimulative effect on the expression of Cx43.

Medical quality and safety are essential safeguards for the harmonious society in China, directly affecting people's sense of security and happiness. Continuously improving medical quality and ensuring medical safety are fundamental and essential to implementing the strategies of the Party Central Committee and the State Council, and promoting the construction of a healthy China. In recent years, with the rapid development of China's economy and the people's increasing emphasis on their own health and safety, China's plastic surgery industry has achieved significant progress and yielded outstanding results. However, along with the rapid growth of the industry, medical quality issues and safety accidents have occurred frequently, attracting widespread attention from all sectors of society. This article briefly outlines the history of quality management and quality control for medical quality and safety in China's plastic surgery specialty. It explores the development of quality management from its origin to medical quality management, as well as the responsibilities and contributions of the National Plastic Surgery Quality Control Center in improving industry standards and ensuring patient safety. It aims to provide support for the standardized management of the plastic surgery industry in the future, so as to promote its healthy and sustainable development.

To compare and understand the trends in quality control data changes in public and private medical institutions specializing in plastic and aesthetic major in China over the past three years.

Objective: To compare the difference of infrared radiation temperature on body surface of points between healthy people and patients with hyperplasia of mammary glands. Method: The thermaCATMT P30 infrared thermal imaging system was selected to measure the infrared radiation temperature on body surface of eight points in four meridians in 74 patients with hyperplasia of mammary glands and 63 healthy people. Results: The infrared radiation temperatures on body surface of right Youmen (KI 21) in cases with hyperplasia of mammary glands were significantly higher than the healthy people (P=0.009), and the infrared radiation temperatures on left Youmen (KI 21) and other points had no significant difference with healthy people (P>0.05). Conclusion: The infrared radiation temperatures on body surface of right Youmen (KI 21) have significant differences with healthy people. This might occur because of the pathogenesis of hyperplasia of mammary glands and of the specificity of the point Youmen (KI 21).

To construct a quality control indicators system for Chinese plastic and aesthetic major and lay foundation for medical quality control.

Objective:To verify that hypoxia induces epithelial mesenchymal transition in HaCaT cells, and to observe the effect of LncRNA HOTAIR on epithelial mesenchymal transition in HaCaT cells.Methods:From Jan. 2018 to Dec. 2018 in Chinese Academy of Medical Science, HaCaT cells were divided into four groups: group A cultured under normoxia, group B cultured under hypoxia, group C transfected with sh-control cultured under hypoxia, and group D transfected with sh-LncRNA HOTAIR cultured under hypoxia. After 36 hours of culturing, the expression of E-cadherin and vimentin were detected using qPCR and Western blot. The migration of HaCaT cells was evaluated by Transwell assay.Results:The relative quantity of E-cadherin mRNA in the four groups were 3.076±0.271, 1.000±0.089, 1.024±0.222, and 2.595±0.085, while vimentin mRNAs were 1.002±0.183, 4.170±0.279, 4.111±0.477, and 2.412±0.134, respectively. In addition, the Transwll invasion assay showed that numbers of cell migration in the four groups were 32.70±3.93, 125.40±6.26, 120.10±6.79, and 58.24±7.06, respectively.Conclusions:The study suggests that hypoxia promotes epithelial mesenchymal transition in keratinocytes. Furthermore, downregulation of HOTAIR is noted to inhibit epithelial mesenchymal transition of keratinocytes under hypoxia condition.
