Wound healing is a complicated biological process, which consists of inflammatory cells, re-pairing cells, extracellular matrix, cell factors, et al. These factors participate in the process of wound heal-ing in great harmony and coordination. The sufferers of diabetes mellitus are vulnerable to skin injury ,which often results in non-healing or healing delay, which became an urgent difficulty and warm spot unsolved in clinic. So far, especially for the last few years, great progress has been made in the mechanism of wound non-healing of Diabetes Mellitus, mainly including signal pathways, angiopoiesis, neuropeptides, advanced glycation end products, cell apoptosis and matrix metaltoproteinases.

Estrogen is involved in the process of postmenopausal osteoporosis, and the main functional cells are osteoclasts. However, the mechanism of estrogen on the osteoclasts is not yet fully understood. Here we demonstrate the effects of estrogen on osteoclasts in three aspects: morphology and structure, apoptosis of osteoclasts and differentiation of preosteoclasts, which give an overall explanation for effects of estrogen on osteoclasts.

ObjectiveTo investigate the changes of serum growth hormone (GH)/insulin-like growth factor- Ⅰ ( IGF- Ⅰ ) in patients with traumatic long bone fractures and the related clinical significance.MethodsTwenty-one patients with traumatic long bone fractures from the same trauma care center treated between November 2009 and April 2010 were enrolled in the study..There were 14 males and 7 females,at age range of 22-60 years (mean 45.0 years).Seventeen patients (81%) were with closed trauma and four ( 19% ) with open trauma.Enzyme Linked Immunoadsorbent Assay (ELISA) was used to determine the levels of serum GH and IGF- Ⅰ within 14 days after fractures and the relationship between changes of GH-IGF- Ⅰ axis and injury severity score (ISS) was further analyzed.Eight patients with normal GH/IGF- Ⅰ were set as control group.ResultsThe GH level in the peripheral blood was significantly higher at day 1 after fractures ( P < 0.05 ),and rapidly declined and stabilized at day 5 compared with the control group.The GH level in the patients with ISS≥ 18 points was sigmficantly higher than that in those with ISS<18 points at day 1 after fractures (P<0.05).The IGF- Ⅰ level in the peripheral blood in the patients with 1SS≥ 18 points was significantly higher than that in those with ISS < 18 points at days 5-10 after fractures ( P < 0.05 ).ConclusionThe hypothalamus GH-IGF- Ⅰ axis plays an important role in early metabolism and fracture healing during the acute phase of traumatic long bone fractures.

Objective:To study the functional status of the monocytes-derived dendritic cells (DCs) plused with HBsAg from patients with chronic hepatitis B and their capacity of inducing the HBV- special cytotoxic T lymphocytes (CTLs),and explore a new method of inducing the special anti-HBV cell-mediated immunity.Methods:Monocytes of patients were isolated from peripheral blood and incubated with GM-CSF+IL-4+TNF-? to induce DCs generation. Those DCs were pulsed with HBsAg to induce HBV- special DCs. The phenotype of DCs including CD1a,CD80,CD83,CD86,CD40 and HLA-DR was characterized by FCM and the stimulating reaction of allogenic T lymphocytes was detected by MTT assay. The concentration of cytokines such as IL-12 and IL-6 in supernate was tested by ELISA and the cytotoxicity of CTLs inducing by the DCs against HepG2 2.2.15 cells,HepG2 cells and K562 cells were detected by LDH assay.Results:The expression of CD1a, CD80, CD83,CD86, CD40, HLA-DR molecules on the DCs pulsed with HBsAg was higher than those of the control group (P

Objective To evaluate the efficacy of laparoscopic Miles surgery at differented periods.Methods Radical excision(Miles) was performed under a laparoscope on 33 patients from January 2002 to August 2002(group 1),and then on 34 cases from July 2006 to May 2007(group 2) in our hospital.Clinicopathological and follow-up data of the two groups were collected and analyzed.Results No significant difference was found in blood loss(50-200 ml vs 40-210 ml,Z=1.477,P=0.787),number of resected lymph nodes(both 3-5,Z=-0.089,P=0.233),gas expel(in 1-3 days after the surgery vs 1-4 days,Z=-1.622,P=0.574),and postoperative hospital stay(4-9 days vs 5-9 days,Z=-1.834,P=0.346) between the two groups.However,the patients in group 1 had significantly longer operation time and higher medical cost than group 2(175-210 min vs 120-150 min,Z=4.238,P=0.026;23400-27500 yuan vs 19863-22744 yuan,Z=5.283,P=0.003).Conclusion After 4-year development,the operation time and cost of laparoscopic Miles surgery has been decreased.

Objective Acute respiratory dysfunction (ARD) can occur after aortic surgery with the use of cardiopulmonary bypass and deep hypothermic circulation arrest, but relatively little is known about acute respiratory dysfunction in the patients with type A aortic dissection. This study aims to analyze the independent risk factors of acute respiratory dysfunction after A type aortic dissection surgery and to assess possible prevention and treatment option in the future. Methods Clinical data of the 252 patients including 193 male patients and 59 female patients who underwent type A aortic dissection surgery from February 2009 to October 2010 were collected. The mean age was 47 years. Postoperative acute respiratory dysfunction was defined as oxygenation impairment (PaO2/FiO2 < 150) that occurred within 72 h of surgery except pleural effusion, cardiogenic pulmonary edema, pneumonia, pulmonary embolism and haemato-/ pneumothorax. There were 187 acute A type aortic dissection patients and 65 chronic type A aortic dissection patients. Clinical characteristics including age, gender, weight, height, history of hypertension, history of smoking, preoperative complications such as preoperative shock and acute renal failure, pericardial effusion, previous cardiac surgery, time from event to surgery, malperfusion syndrome, cardiopulmonary time, cross-clamp time,deep hypothermia circulation arrest time, surgical procedure, duration of intensive care unit stay and postoperative complications including tracheotomy, dialysis dependent renal failure and hospital mortality were gathered. Arterial blood analysis, chest X ray, ventilator parameters, number of blood transfusion and flood balance were assayed after operation. All the factors were evaluated by means of univariate and multivariate logistic regression analysis to identify relative risk factors of ARD. Results Acute respiratory dysfunction occurred in 32 (12.7% ) patients. The in-hospital mortality was significant difference between acute respiratory dysfunction group and non- acute respiratory dysfunction group (P < 0.05). The value of BMI, incidence of acute aortic dissection, preoperative SBP level, cardio-pulmonary bypass time, aortic clamp time and total arch replacement in acute respiratory dysfunction group were significantly higher than the values in non- acute respiratory dysfunction group. Multivariate Logistic regression analysis showed blood transfusion more than 10 units and cardio-pulmonary bypass time more than 160 minutes were independent risk factors of early stage acute respiratory dysfunction after type A aortic dissection surgery.Conclusion Acute respiratory dysfunction after type A aortic dissection was a severe early stage postoperative complication and was associated with in-hospital mortality. The patients in acute aortic dissection were prone to have acute respiratory dysfunction. The independent risk factors of acute respiratory dysfunction included blood transfusion more than 10 units and cardio-pulmonary bypass time more than 160 minutes.
