Objective To investigate the clinical value of minimally invasive rotary resection in the treatment of mastitis with abscess formation. Methods A total of 93 cases with mastitis with abscess formation in our hospital from October 2010 to December 2014 were divided into two groups according to patients ’ willingness: one group was given ultrasound-guided Mammotome rotary surgery and drainage (minimally invasive group, n=45), the other underwent incision and drainage (control group, n=48).Surgical parameters, postoperative complications and patient satisfaction were compared between the two groups. Results The minimally invasive group was significantly superior to the control group in the operative time, blood loss, healing time, postoperative scar length and postoperative complications [(16.0 ±4.4) min vs.(30.6 ±6.8) min, t=-12.339, P=0.000;(8.5 ±2.3) ml vs.(12.7 ± 4.1) ml, t=-6.102, P=0.000;(10.1 ±1.9) d vs.(14.3 ±3.3) d, t=-7.595, P=0.000;(4.6 ±1.2) mm vs.(40.5 ± 11.8) mm, t=-20.913, P=0.000;8.9%(4/45) vs.25.0% (12/48), χ2 =4.232, P=0.040].Follow-up reviews at 3-6 postoperative months showed the comprehensive satisfaction of operation was significantly higher in the minimally invasive group (37/45, 82.2%) than that of control group (28/48, 58.3%) (χ2 =6.299, P=0.012). Conclusion For mastitis with abscess formation, minimally invasive rotary surgery has characteristics of minimal invasion, quick postoperative recovery, good cosmetic effects, few complications and high patients’ postoperative satisfaction.It deserves further clinical application.

Objective To observe the clinical curative effect of phentolamine in the treatment of severe hand-foot-mouth disease (HFMD) . Methods We observed the clinical symptoms and related index changes before and after treatment of 62 cases of severe HFMD patients who were treated by the basis of conventional therapy with additional phentolamine. The blood pressure of patients was closely monitored,and the dosage of phentolamine was adjusted. Result The blood pressure and heart rate of sick children who used phentolamine improved significantly, the difference was statistically significant ( <0.05) . Conclusion Phentolamine has significant clinical curative effect in treatment of server HFMD.

A new nested-polymerase chain reaction (nested-PCR) assay was developed to detect human parvovirus B19 DNA corresponding to the nonstructural protein in clinical specimens in a routine diagnostic laboratory. The sensitivity of this highly specific assay was up to 0.005 fg of B19 DNA. Parvovirus B19 was identified in sera of 20 pregnant women with abnormal pregnant outcome. Among these 20 cases, intrauterine parvovirus infection did exist in 7 pregnant women because parvovirus B19 DNA was detected in the pregnant tissues of them such as placenta tissues, chorionic villi, amniotic fluid, fetal spleen, liver and abdominal fluids.

Objective To summarize the clinical efficacy of interventional treatment for lower extremity arteriosclerosis obliterans and its complications.Methods We analyzed sixty-nine patients with lower extremities arteriosclerosis obliterans undergoing interventional treatment from October 2011 to January 2013.During the same period,three patients were referred to us who suffered from the complications of interventional treatment.In these patients,eight were TASC ⅡA type,twenty-one were TASC Ⅱ B,twenty TASC Ⅱ C,and twenty-two TASC Ⅱ D lesions.All patients received CTA or DSA.Seventy patients were treated by interventional treatment,and two who had fractured stent underwent external iliacsuperficial femoral artery bypass grafting using artificial grafts.Results The technique success rate was 100％.The symptoms disappeared after surgery.During interventional treatment,one iliac artery ruptured,one patient suffered from arterial perforation and three patients suffered from distal embolization.Sixty-eight patients were followed-up for 9 ± 4 months.Conclusions Endovascular treatment has good early clinical efficacy.In order to reduce the incidence of complications,indication of interventional treatment should be controlled strictly and manipulation should be careful.
