Objective To investigate the effect of lysostaphin on golden staphylococcal bacteria in vitro and on acestoma tissue.Methods Effects of lysostaphin on golden staphylococcal bacteria,Candida albicans and P.aeruginosa were detected by drug sensitivity test.Quantitative analysis of bacteria was used to detect the effect of lysostaphin on golden staphylococcal bacteria in 29 cases of 10%-30% TBSA.Results Most golden staphylococcal bacteria,as well as Candida albicans could be killed by lysostaphin.Lysostaphin had little effect on P.aeruginosa.Eighty-nine percent bacteria could be killed by lysostaphin after gauze with lysostaphin had been used for over 3 d,indicating lysostaphin may control bacteria quantity and improve survival rate of skin graft on granulation tissue.Gauze with lysostaphin contained biological enzymes and it had no systemic side effects.Conclusion Gauze with lysostaphin may be available on controlling golden staphylococcal bacteria as well as Candida albicans in burnt patients.Lysostaphin is effective in controlling residual trauma infected by golden staphylococcal bacteria.

MiR-494 involves in cell cycle regulation,differentiation and apoptosis processes of normal ceils.Recent study shows that abnormal expression of miR-494 is associated with oncogenesis closely,and it participates in the invasion and metastasis of tumor cells and so on.MiR-494 is not only a tumor suppressor gene,but also can be considered as a cancer-promoting gene.MiR-494 can regulate the oncogenesis and development of the tumor through a variety of target genes and signaling pathways.

BACKGROUND: The traditional treatment for skin donor site wound was focus on anti-infection and wound protection, which roof a long time for healing. Studies demonstrated that recombinant human epidermal growth factor (rhEGF) has accelerated effect or epidermal regeneration. OBJECTIVE: To observe the effect of rhEGF on wound healing of skin donor site. METHODS: A total of 32 cases needs wound healing by skin grafting were collected, including 18 males and 14 females. The 32 skin graft donor site wounds were randomly divided into control and treatment groups. In the treatment group, the absorbent gauze was sprinkle soaked with rhEGF (15 mL/ramus, 2 000 IU/mL) and covered the donor site, twice per day. In the control group, donor site was covered by physiological saline gauze and wrapped with dressing, twice per day. After 48 hours, semi-exposed therapy was performed. The healing time of wounds, the systemic and local adverse reactions of patients and blood routine examination and renal function detection prior to and after treatment were observed. RESULTS AND CONCLUSION: The healing time of wound in the rhEGF treatment group was shorter than that in the control group with significant differences (P < 0.01). No Adverse events or side effects were observed in the rhEGF treatment group. rhEGF can shorten wound healing time, reduce scar hyperplasia, and accelerate epithelization at the graft donor.

OBJECTIVETo analyze and summarize the clinical features and experience in surgical treatment of deep sternal infection (DSWI).
METHODSThis was a retrospective study. From January 2008 to December 2013, 189 patients with secondary DSWI after cardiac surgery underwent the pectoralis major muscle flap transposition in our department. There were 116 male and 73 female patients. The mean age was (54 ± 21) years, the body mass index was (26. 1 ± 1. 3) kg/m2. The incidence of postoperation DSWI were after isolated coronary artery bypass grafting (CABG) in 93 patients, after other heart surgery plus CABG in 13 patients, after valve surgery in 47 patients, after thoracic aortic surgery in 16 patients, after congenital heart disease in 18 patients, and after cardiac injury in 2 patients. Clean patients' wound and extract secretions, clear the infection thoroughly by surgery and select antibiotics based on susceptibility results, and then repair the wound with appropriate muscle flap, place drain tube with negative pressure. Of all the 189 patients, 184 used isolate pectoralis, 1 used isolate rectus, and 4 used pectoralis plus rectus.
RESULTSThe operative wounds of 179 patients were primary healing (94. 7%). Hospital discharge was postponed by 1 week for 7 patients, due to subcutaneous wound infection. Subcutaneous wound infection occurred again in 8 patients 1 week after hospital discharge, and their wounds healed after wound dressing. Nine patients (4. 7%) did not recover, due to residue of the sequestrum and costal chondritis, whom were later cured by undergoing a second treatment of debridement and pectoralis major muscle flap transposition. Eight patients died, in which 2 died of respiratory failure, 2 died of bacterial endocarditis with septicemia, 2 died of renal failure, 1 died of intraoperative bleeding leading to brain death and the 1 died of heart failure. The mortality rate was 4. 2% . The average length of postoperative hospital stay was (14 ± 5) days. The longest postoperative follow-up period was 40 months, the median time was 26 months, the follow-up rate was 83. 9% . Totally 179 patients were no-reinfected, 2 patients were reinfected because of artificial vascular rejection.
CONCLUSIONTo perform surgical debridement and then reconstruct the sternal defect with pectoralis major muscle flap actively for the patient is an effective measure to improve patient's survival rate.

Objective To observe the correlation between CD4+ CD29+ T cells and metastasis and radiotherapy for patients with pulmonary adenocarcinoma. Method Seventy-one patients with lung adenocarcinoma, 93 patients with lung adenocarcinoma ,76 cases of chronic obstructive pulmonary disease (COPD),63 cases of healthy volunteers were enrolled. Frequencies of blood CD4+ CD29+ T cells and their intracellular necrosis factor alpha(TNF-α)and interleukin 1(IL-1)were compared. Compare TNF-α,IL-1,integrin beta 1 and vascular endothelial growth factor(VEGF)levels in the patients with transferred pulmonary adenocarcinoma or with non-transferred pulmonary adenocarcinoma and their changes with the treatment of radiotherapy. Results the patients with lung adenocarcinoma and non lung adenocarcinoma were significantly higher than that of COPD and health group,and patients with lung adenocarcinoma is significantly higher than patients with non lung adenocarcinoma (P<0.05);Integrin beta 1,VEGF and CD4+CD29+T cells,TNF-αand IL-1 level in patients with lung adeno-carcinoma metastasis were significantly higher than non-transferred group(P < 0.05);After radiotherapy,CD4+CD29+T cells,TNF-αand IL-1 in patients with lung adenocarcinoma were significantly lower than before(P<0.05);CD4+ CD29+ T cells,TNF alpha and IL-1 with integrin beta 1 and VEGF had significantly positive correlations. Conclusion CD4+CD29+T cells and cytokines increase significantly in the blood of patients with lung adenocarci-noma,and are related to the prognosis of metastasis and radiation therapy,which has important clinical significance.

China Modern Doctor 2009;47(18):8-9,17
Objective To investigate the relationships between serum visfatin and glucose and lipid metabolism in type 2 diabetes (T2DM). Methods ELISA method was employed to measure the serum vifatin levels between 110 T2DM cases (T2DM group) and 80 healthy controls (control group), and the levels of the indices of the glucose and lipid metabolism were detemined. Results The semm levels of the visfatin were considerably higher in both the non-obese and obese subgroup in T2DM group than those in the control group, showing significant differences between two groups(P< 0.01, t=26.545, 15.111, 25.017, 14.764 respectively). No significant differences were noted between the non-obese and obese subgroup in both two groups (P> 0.05,t=0.760,1.506). The level of the visfafin was positively related to WHR,FBG, HbA1c,HOMA-IR,TC and LDL-C in the T2DM group and negatively to HDL-C,all P< 0.01. Multiple stepwise regression results showed that WHR and HbA1c were predominant factors affeeting the visfatin levels(R2=0.547,0.033 respectively). Conelusion Increased visfatin proves to be directly associated with glucose and lipid metabolism in T2DM, acting as one of the major adipoeytokines connecting the glucose and lipid metabolism.
