Objective To analyze clinical and bacteriological features and therapeutic methods of erysipelas following breast cancer surgery in 12 hospitalized patients. Methods Clinical data on 12 patients with erysipelas following breast cancer surgery were collected from 3 third-grade class-A hospitals in Ningbo. A retrospective study was carried out. Results Of the 12 patients, 8 were treated with modified radical mastectomy and axillary lymph node dissection, 3 with radical mastectomy and axillary lymph node dissection, and 1 with mammectomy only. All of the 12 patients suffered from postoperative lymphedema on the affected side. Erysipelas mostly occurred within 1 - 18 years (mean, 8.0 years)after breast cancer surgery, and on the same side of surgery in all the patients except 2 with multi-site infection. Specifically speaking, erysipelas was located in the upper extremity in 8 patients, in the chest wall in 1 patient, in the lower extremity in 1 patient. Blood culture was performed for 5 patients, of whom, 2 showed positive results, including 1 infected with Streptococcus equisimilis and 1 with Klebsiella pneumonia. Six patients were treated with penicillins, but the primary treatment failed in 2 patients. After replacement of antibiotics, all the 12 patients experienced an improvement of the condition and were discharged from hospital. Conclusions Patients who suffer from lymphedema after breast cancer surgery are prone to erysipelas of the upper limbs and chest wall. Caution should be taken against gram-negative bacterial infections in these pateints. The treatment of lymphedema should be taken into account besides antibiotic therapy.

Objective To investigate the expressions of CXC chemokine receptor 3 (CXCR3) and CD1a in skin lesions of different stages of mycosis fungoides (MF). Methods The expression and distribution profiles of CD1a and CXCR3 were detected by immunohistochemistry in the epidermis of skin samples from 16 normal human controls, 16 patients with non-tumor (patch/plaque) stage MF and 8 patients with tumor stage MF. Results With the progression of MF from patch/plaque stage to tumor stage, the positivity rate of CXCR3 in intraepithelial neoplastic cells in lesions dropped from 38.9% to 17.5% (P ＜ 0.05). The average number of intraepithelial Langerhans cells (LCs) per high power field (HPF) in skin samples was 10.6 in patch/plaque stage MF, significantly higher than that in normal control (7.3) and tumor stage MF (6.7), while no significant difference was found between normal control and tumor stage MF specimens. Conclusion The epidermotropism in MF may be associated with the expression of T-helper (Th) 1-associated chemokine receptor (CXCR3) and quantity of intraepithelial LCs.

Objective To observe the clinical curative effect of Danhong injection combined with atorvastatin calcium in the treatment of lacunar cerebral infarction of the elderly.. Methods 125 elderly patients with lacunar cerebral infarction were randomly recruited into two groups, a control group(n=60 cases) was treated with atorvastatin calcium on the basis of conventional symptomatic treatment, and an observation group (n=65 cases) was treated with Danhong injection combined with atorvastatin calcium on the basis of conventional symptomatic treatment, the courses of two groups were 14 d. The clinical curative effect, the degree of nerve function defect score, the changes of hemorheology of two groups before and after the treatment were compared. Results The total effective rate of the observation group(89.2%)was significantly higher than that of the control group(71.7%)(P<0.05). The degree of nerve function defect score(16.24±4.63)of observation group after treatment improved significantly better than that of control group(22.17±7.38), P<0.05, and the whole blood viscosity(high), whole blood viscosity(low), plasma viscosity and fibrinogen [(3.62±0.64)mPa?s,(8.07±2.45)mPa?s, (1.61±0.30)mPa?s, (2.76±0.28)g/L]decreased significantly than that of the control group[(4.73±0.85)mPa?s, (9.86±3.26)mPa?s, (2.05±0.33)mPa?s,(3.94±0.35)g/L], P<0.05. Conclusion The treatment of Danhong injection combined with atorvastatin calcium for elderly lacunar cerebral infarction had a good therapeutic effect. It could improve nerve function defect degree and blood rheology indexes.

Objective To study the relationship between the therapeutic principle and prescription of traditional Chinese medicine and the experimental pharmacologic effects in relation to the treatment of eczema. Methods Murine DNFB allergic contact dermatitis was used as an animal model, and was treated with 4 traditional Chinese medicinal compounds which were composed of Chinese materia medica with activities to suppress type Ⅳ allergic reaction. Results The results showed that the effect of compound Ⅲ composed of Paeoniae obovata Maxim(赤芍), Fructus Gardeniae(栀子), Herba Schizonepetae(荆芥), Herba Spirodelae(浮萍) and Poria(茯苓), possessing multiple potencies of cooling and promoting blood, clearing heat, expelling wind and eliminating dampness, was strongest among the compounds tested, and the compound up regulated the serum level of calcitonin gene related peptide which was lowered in the mice with DNFB induced dermatitis. Conclusion It is suggested that the compounds with suppressive effect on type Ⅳ allergic reaction might improve the therapeutic effect in clinical practice.

Objective To study the possible role of cytokines interleukin-1beta(IL-1?),interleukin-6(IL-6),interleukin-8(IL-8),tumor necrosis factor alpha(TNF-?)and granulocyte macrophage colony stimulating factor(GM-CSF)in the pathogenesis of vitiligo.Methods The serum levels of IL-?,IL-6,IL-8,TNF-?,and GM-CSF were measured in50patients with vitiligo and20healthy volunteers with radioimmunoassay.Results The serum level of IL-6and GM-CSF in focal type and generalized type of vitiligo,and the serum level of IL-1?in generalized type were significantly higher than those in normal controls.In segmental type of vitiligo,the serum levels of all the cytokines tested were not significantly different from those in normal controls.The GM-CSF levels in focal type and generalized type,and the IL-6level in generalized type of the progressive stage were significantly higher than those in the stable stage.Conclusion IL-6and GM-CSF may be involved in the autoimmune mechanism of non-segmental type of vitiligo.

Objective To investigate the effect of target-controlled infusion(TCI) of propofol on global and regional eerobral glueose metabolism in humans studied with positron emission tomography(PET).Methods Five healthy right-handed male volunteers aged 22-30yrs, weighing 58-72 kg underwent PET sean to assess glucose metabolism when they were awake and unconseions. The interval between the two PET seans was longer than 1 week. The unconseious state was induced by TCI of propofol. The initial effeet-site concentration(ESC) of propofol was set at 2.5?g?ml~(-1) and was modulated in ?0.2?g?ml~(-1) increments until OAA/S score roached 1(no response to prodding). Then the ESC was maintained during PET scanning. The dynamic scans were performed at 0-4.5 min(T_1), 4.5-9.5 min(T_2), 9.5-29.5 min(T_3), 29.5-44.5 min(T_4), 44.5-59.5min(T_5) and 59.5-74.5 min(T_6) after the end of FDG 10 mci injection. After the data were reconstructed we used the stereotactic method to select the following regions of interest(ROI): the whole brain, frontal lobe, temporal lobe, parietal lobe, occipital lobe, putamen, caudate nucleus, thalamus and cerebellum ets. The ROI data were then transformed into standard uptake value(SUV). The difference and percentage decrease in SUV of the different ROI between eonscious and unconscious state at different intervals were compared. Results The SUVs of the whole brain and all ROIs were significantly decreased in unconscious state during T_(3-6) compared with those in conscious state. In unconscious state at T_6 the percentage decrease in SUV of different ROIs was different-42.38% (occipital lobe), 35.52%(frontal lobe) and 21.40%(putamen). The percentage decrease in SUV of thalamus was similar to that of occipital lobe, temporal lobe and parietal lobe but higher than that of frontal lobe. The sequence of SUVs of cortex and subcortioal centers in conscious state during T_(4-6) and in unconscious state during T_(3-5) were the same: temporal lobe
