OBJECTIVETo observe the efficacy of the treatment of refractory wound by VSD combined with platelet-rich plasma.

METHODSFrom April 2010 to June 2012,15 patients with refractory wound were treated including 11 males and 4 females with an average age of 35.2 years old ranging from 18 to 45 years old. The formation time of wound was from 6 to 24 months, which was unhealed after long-term medication or repeated treatment. The VSD combined with autologous platelet-rich plasma was applied to treat the wound. The wound healing was an indicator and treatment and clinical features were summarized.

RESULTSAll the patients were followed up for 3 to 8 months (means 5 months). The wound of all patients were healed without recurrence.

CONCLUSIONThe curative effect of VSD combined with platelet rich plasma for treatment of refractory wounds is obvious. It could reduce the treatment course and the treatment cost.

17-allylamino-17-demethoxygeldanamycin (17-AAG) is a heat shock protein 90 ( HSP90) inhibitor. It is capable of target-inhibiting tumor-derived HSP90, leading to the depletion of on-cogenic client proteins which play key roles in several signal transduction pathways. Then cell growth and differetiation are inhibited. 17-AAG results in cytostasis and apoptosis. A lot of trials have indicated that 17-AAG is a selective target drug for cancer therapy. It can efficiently inhibit multiple signal transduction pathways involved in tumor cell proliferation and survival. Clinical phaseⅠand phaseⅡtrials have shown that 17-AAG has good pharmacokinetic-pharmacodynamic profile. Moreover, it can combine with radiation and the traditional chemotherapeutics and increase the therapeutic efficacy.

Objective:To study the change of immunological response and cell proliferation in breast tissues augmented by polyacrylamide hydrogel injection(PHI).Methods:The expression of CD68,CD25 and PCNA in 20 breast tissues with indurations,12 without indurations after breast augmentation by PHI,and 10 normal breast tissues was examined by immunohistochemistry P-V6000; analysis was also done by H-E staining.Results:Hyperplasia of fibrous tissue and infiltration of inflammatory cells and macrophages were found in the breast and adjacent tissues 3-8 years after PHI.Positive cells of CD68,CD25 and PCNA hardly existed in the normal tissues,but the breast tissues around the polyacrylamide hydrogel had many positive cells of CD68 and PCNA,especially in cases with indurations;there were significant differences between the 3 groups(P

Objective To investigate the effects of vitamin D deficiency on pregnancy and fetal development in mice. Methods All female ICR mice were randomly divided into two groups. In control group, mice were fed with standard feeds (vitamin D3 >800 IU/kg). In vitamin D deficiency group (VDD), female mice were fed with feeds with vitamin D depletion (vitamin D3 <25 IU/kg). For mating purposes, four females were housed overnight with two males starting at 9 : 00 PM. Females were checked 7 : 00 AM the next morning, and the presence of a vaginal plug was designated as gestational day (GD) 0. All pregnancy mice were sacrificed on GD18. For each litter, the number of live fetuses, dead fetuses and resorption sites were counted. Live fetuses in each litter were weighed. Crown-rump lengths were examined. And skeletal development of all live fetuses in each litter was evaluated. Re-sults The pregnancy rate was lower in VDD group than that in control group(P<0.05). The number of live fetu-ses was significantly decreased(P<0.05). By contrast, the numbers of dead fetuses and resorption sites were sig-nificantly increased(P<0.05). In addition, the average weights of fetuses and placenta were reduced in vitamin D deficiency group. Moreover, vitamin D deficiency resulted in skeletal development retardation in fetuses. Conclu-sion Vitamin D deficiency impairs pregnancy and developmental outcomes in mice.

Objective To assess the risk factors for the occurrence of hypokalemia in patients with hepatic cancer after transcatheter arterial chemoembolizaion (TACE) therapy,and to discuss the corresponding nursing countermeasures.Methods The clinical data of 214 patients with hepatic cancer,who received TACE during the period from August 2014 to February 2015,were retrospectively analyzed.The risk factors causing hypokalemia were analyzed.Results Among the 214 patients,post-TACE hypokalemia occurred in 23 (10.7％).The main risk factors that could cause hypokalemia included anorexia,hydration,vomiting,ascites drainage,sweating.After actively symptomatic treatment,the serum potassium level returned to normal in 22 patients.One patient developed hepatic encephalopathy coma complicated by hepatorenal syndrome,the patient's family members gave up treatment and,according to family members' will the patient left hospital.Conclusion anorexia,vomiting,hydration,ascites drainage,sweating are the risk factors that can cause hypokalemia in patients with hepatic cancer after TACE therapy.The use of low potassium risk scale is helpful for the formulation of nursing countermeasures.

Objective To explore the therapeutical effects of enteral nutrition (EN) combined with panaxoside Rb1 on mouse modles of postoperative fatigue syndrome. Methods Totally, 72 male Sprague-Dawley mice were randomly divided into control group, model group, EN group, EN associated with high/middle/low dose panaxoside Rb1 groups (EHP group, EMP group, and ELP group, n = 12 in each group). Changes in body weight were measured before and after interventions. Learning and memory playback abilities, physical strength,and vim state were evaluate by Morris Water Maze test and Improved Tail Suspension test. Serum transferrin, prealbumin, fibronectin, and interleukin-2 levels were measured with ELISA. Serum albumin level was assayed with Bromcresol Green colorimetric technique. CD4 + and CD8 + proportions were assayed by flow cytometry. Results The body weight grew alternately in each group without significant differences ( P ＞ 0.05 ) except for model group.The latency period was significantly shorter in EN combined with panaxoside Rbl group than that in model group ( P ＜ 0. 05 ) , and the frequencies of crossing platform in EHP group and EMP group were significantly higher than those in model group ( P ＜ 0. 01 ). The areas of struggling above domain in EHP group and EMP group were significantly larger than those in model group ( P ＜ 0. 05 ), and the accumulated static time of rest in EHP group, EMP group, and ELP group was significantly shorter than that in model group ( P ＜ 0.05 ). Serum transferrin, prealbumin, fibronectin levels in EN combined with panaxoside Rb1 group were significantly higher than those in model group ( all P ＜ 0.05 ). The CD4 + T proportion and interleukin-2 level in EHP group, EMP group, and ELP group were significantly higher than those in model group (both P ＜0.05 ); however, CD8 + T proportion was not significantly different between three panaxoside Rbl groups and model group (P ＞ 0. 05 ). Conclusion EN combined with panaxoside Rb1 can improve postoperative fatigue syndrome in a dose-dependent way, which may be explained by the fact that it can strengthen the postoperative nutrition, restrain hypermetabolism, and increase immunity.

Objective: To investigate the stamina,the role of antioxidant system in severe acute pancreatitis(SAP),and the effect of fish oil treatment in rats.Methods:Thirty-six male Sprague-Dawley rats(SD) were randomly divided into three groups,including SAP group(sodium chloride treatment ) (group NSG,n=12),fish oil treatment group (group FOG,n=12),and control group (group CG,n=12).SAP was induced by intergraded injection of 3.5% sodium tanrocholate to biliopancreatic duct of SD rats in group NSG and FOG.The group NSG rats were treated by subcutaneous injection of sodium chloride,while the group FOG rats were treated by subcutaneous injection of fish oil for 7 days.Then the improved tail suspension test was observed at the first,third,fifth,seventh day.12 rats in each group were respectively sacrificed after 7 day.The activity of serum antioxidant enzymes (MDA,GSH-PH) and the concentration of serum amylase were measured in each group,and the levels of threshold on the area and the total immobility time were measured in each group.The severity of pancreatitis was analyzed according to the histopathological morphology.Results: Compared to group NSG,the severity of pancreatitis was significantly decreased in group FOG.The activity of MDA was significantly increased in group NSG than that in group CG (P<0.01) ,while the activity of MDA in group FOG was decreased than that in group NSG (P<0.05) .The activity of GSH-PH was significantly decreased in group NSG than that in group CG(P<0.01),while the activity of GSH-PH was increased in group GOG than that in group NSG (P<0.05).THE level of threshold on the area was decreased in group NSG than that in group CG(P<0.01),while the level of threshold on the area was increased in group GOG than that in group NSG.(P<0.01) The total immobility time was significantly increased in group NSG than that in group CG(P<0.01),while the total immobility time was decreased in group GOG than that in group NSG(P<0.05).MDA was associated with the level of threshold on the area and the total immobility time.Conclusion: Fish oil has a positive effect on the activity of antioxidant system and behavior character in SAP rats.

Objective To investigate the efficacy of progressive resistance exercise for improving the lower limb motor function of hemiplegic stroke patients. Methods Eighty-nine hemiplegic patients were randomly divided into a treatment group (n =46) and a control group ( n = 43 ) . Both groups received routine rehabilitation training, while the treatment group also undertook progressive resistance training. The control group received extra quadriceps femoris training. Before and after the treatment, motor function was evaluated with the Fugl-Meyer lower limb assessment, functional ambulation category (FAC) classification and the modified Barthel index (MBI). Results Before intervention, there were no significant differences between the two groups in any of the assessments. Four weeks later, all the assessment scores obtained with the Fugl-Meyer lower limb assessment, FCA classification and MBI in the treatment group were significantly better than those in the control group. Conclusion Progressive resistance training combined with routine rehabilitation treatment can improve motor function in the lower limbs, ambulation and ability in the activities of daily living of hemiplegic patients after stroke.
