目的 应用不同冲洗液对慢性创面上应用的封闭负压吸引装置进行冲洗,对比两种冲洗方法的优劣,为临床应用提供参考。方法 对比两组冲洗液冲洗后创面肉芽组织生长情况,疼痛度,堵管率,住院天数,细菌培养及药敏试验结果等情况。结果 呋喃西林组对比于生理盐水组能更好的促进肉芽组织生长[(9.41±1.12) vs (7.76±0.67)],能缩短患者平均住院日[(29.44±1.88) vs (32.79±1.74)]d,但是对于减轻疼痛度、降低堵管率方面两者效果相当(P＞0.01)。同时细菌培养显示创面感染以革兰阴性菌为主,呋喃西林组细菌检出率低于生理盐水组(62.5% vs 82.5%);呋喃西林组部分细菌对呋喃西林产生耐药性,而生理盐水组这种情况较之少见(68% vs 36.36%)。结论 ①呋喃西林冲洗在促进肉芽组织生长,缩短平均住院日方面优于生理盐水组。②两种方法均能有效防止引流管的堵塞情况。③呋喃西林冲洗可降低细菌检出率,但能使部分细菌产生对呋喃西林的耐药性。

Objective: To compare the effects of two different liquid in negative pressure wound therapy for chronic wounds, provide the reference for clinical application. Methods: The growth of granulation tissue, pain degree, plugging rate, average hospitalization days, bacterial culture and drug sensitivity test results were compared after the two liquid was used. Results: Nitrofural group compared with the saline group can promote the growth of granulation tissue[(9.41±1.12) vs (7.76±0.67)], shorten the average days of hospitalization[(29.44±1.88) vs (32.79±1.74)]; but for the relief of pain degree and the plugging rate, the effects was similar(P＞0.01, the difference was not significant). At the same time, bacterial test showed that there were almost gram-negative bacteria, bacteria detection rate (62.5%) in Nitrofural group was less than that in the saline group (82.5%); Nitrofural group has more nitrofurazone resistant bacteria(68%), and the saline group performs not the same(36.36%). Conclusion: ① Furacilin irrigation could promote the growth of granulation tissue, shorten the average hospitalization days. ②The two methods can effectively prevent the blockage of the drainage tube. ② Furacilin irrigation can reduce the detection rate of bacteria, but cannot prevent the resistance of nitrofurazone.

Objective To explore the stabilized total knee arthroplasty effects on early functional changes of condylar offset. Methods 121 cases of posterior stabilized total knee arthroplasty in our hospital from Jan.2013 to Jan.2016 were enrolled in the study. All patients with preoperative and postoperative posterior condylar offset records, according to the changes of femoral condylar offset were divided into A group and B group. The patients in the two groups were followed for at least 12 months, and the differences in the Osteoarthritis Index score (WOMAC), the American Knee association score (KS), HSS score and knee function were compared. Results After surgery, two patients in the anterior condylar offset changes, femoral prosthesis flexion angle, tibial angle, tibial angle difference was not statistically significant (P > 0.05). But after 1 years, the improvement of WOMAC score, HSS score and weight-bearing active flexion range in group A was better than that in group B, the difference was statistically significant (P < 0.05). Conclusions The reconstruction of the posterior condylar offset can improve the stability after total knee arthroplasty in patients with early osteoarthritis symptoms, and enhance the active flexion range of patients with weight-bearing, which has some clinical value.

Objective To analyze the effects of liberal intrapartum postures on the pelvic floor function of postpartum. Methods 610 pregnant women (vaginal delivery,single birth,and head position) were classified and analyzed in Guangzhou Women and Children Medical Center from March 2015 to March 2016. All the pregnant women were mature without pregnancy complications; 298 pregnant women who adopted free posture delivery were selected as observation group,312 pregnant women who adopted traditional posture delivery were selected as control group. We counted the number of perineal injury incidence of the two group,and the pelvic floor strength of the two groups was measured after fetal birth after 6 to 8 weeks. Results We compared the vaginal resting pressure(VRP),vaginal squeezing pressure(VSP),classⅠfiber strength, class Ⅱ fiber strength and the time of vaginal contraction between the two groups. Pelvic floor muscle strength was significantly stronger in the observation group than that in the control group (P<0. 05). Conclusion There is a closely association between the different intrapartum postures and the pelvic floor function of postpartum. Adopting free posture delivery has no adverse impact on pelvic floor function of postpartum, which can protect the function of female pelvic floor.

Methods Staphylococcusaureus strain 34 134 was provided by the First Affiliated Hospital of Guangxi Medical University. Using doubling dilution method to measure the minimum inhibitory concentration of Coptis decoction and Oxacillin sodium on Staphylococcus aureus,respectively. In vitro, peritoneal dialysis tube was used to establish Staphylococcus aureus biofilm model after adding different concentrations of Coptis decoction and Oxacillin sodium for 3 days and 7 days, we used Agar plate count method to assess bacterial adhesion on the dialysis tube, crystal violet staining and semi quantitative method to measure the BF of the surface of the carrier and silver staining(light microscopy) rapid identification of BF.

Objective By analyzing and comparing the effects of different revascularization strategies on patients with acute myocardial infarction complicated with multi-vessel disease, to explore its clinical value.Methods Selecting the patients with acute myocardial infarction complicated with multi-vessel disease from August, 2012 to August, 2015 in our hospital (Zhaoqing No.2 People's Hospital), after each patient was successfully treated with PCI, divided them into experimental group and control group by random number table method, the experimental groups were treated with preventive emergency PCI after the onset 7-10 days, and the intervention of non-infarct-related vascular diseases were done;the control groups were treated with emergency PCI for the non-infarct-related vascular diseases according to the patient's lack of blood. Visiting them randomly for 2 years, the main cardiac adverse events, other cardiovascular events and one more emergency PCI situation in the two groups were recorded.Results A total of 450 patients completed two years of follow-up, with 226 patients in the experimental group and 224 patients in the control group. All-cause mortality (χ2=7.040,P=0.008), cardiac adverse events (P> 0.05)and incidence of heart failure (χ2=1. 527,P=0.217) were no statistically significant difference between the two groups. Compared with the control group, the incidence of angina pectoris (χ2=21.092,P<0.001), cardiologic rehospitalization (χ2=22.893,P<0.001)and one more stent treatment (χ2=17.835,P<0.001) of the experimental group was significantly lower, but the revascularization rate was higher of their related blood vessels. And when the experimental group was followed up for 2 years, the taking rate of β-blockers (χ2=7.040,P=0.008) and nitrates (χ2=63.889,P<0.001) was significantly higher.Conclusion After the patients with acute myocardial infarction complicated with multi-vessel disease were successfully treated with emergency PCI to intervene the infarct-related blood vessels, and at the same time the intervention of the non-infarct-related blood vessels were done, the recurrence of angina pectoris, stent treatment and cardiopulmonary rehospitalization was significantly reduced.

Objective To understand the mental health status of community health care workers, assess the effect of psychological intervention measures, and find effective measures to improve the mental health status of community health care workers.Methods With the help of Symptom Checklist SCL-90, we firstly carried out baseline survey on community medical staff mental health; then retested that at 3, 6 and 9 months later. Thus, we could assess the effect of psychological intervention. According to the results of the medical staff working pressure test questionnaire, we could develop targeted psychological intervention measures and adopt prompt adjustment.Results Community health care personnel SCL-90 evaluation score and 7 factors scores(physical,forced,interpersonal sensitivity,anxiety,hostility,terror,and paranoia) were higher than the national norm(P<0.05);after comprehensive intervention in the 9 months follow-up,the SCL-90 evaluation score was decreasing gradually.After intervention for 6 months,except for the interpersonal sensitivity factor,SCL-90 total scores and the other factor scores tend to normal levels, to compare the national norm, there was no statistical significance in differences (P<0.05). 9 months later, the scores of interpersonal sensitivity also return to normal levels.Conclusion The mental health status of community health care workers was lower than the national norm,the comprehensive intervention may improve their mental health level, and the experiment showed that the intervention should be no less than 6 months.
