ObjectiveTo investigate the relationship between the change of circulating endothelial cell (CEC) level and coronary artery lesion (CAL) of Kawasaki disease (KD),and to further explore the method for early diagnosis of KD.MethodsThirty KD children were recruited for study,including 23 children with complete type of KD and seven children with incomplete KD.According to the results of echocardiography,the KD group was divided into CAL group (9 cases) and non-coronary artery lesion (NCAL)group (21 cases).Ten healthy children were enrolled as control group.Double-blind and controlled trial was conducted,and Hladovec method was applied for CEC counting.Results The CEC level was ( 1.09 ±0.60) × 107/L in KD group,which was higher than that of control group [ (0.38 ±0.14) × 107/L],and the difference was statistically significant ( t =2.85,P ＜ 0.01 ).The CEC level in the CAL group [ ( 1.84 ± 0.24) × 107/L] was higher than that of the NCAL group[ (2.01 ±0.38) × 107/L],and the difference was statistically significant ( t =2.24,P ＜ 0.05 ).The CEC level was ( 1.16 ± 0.63 ) × 107/L in the complete type of KD group and (0.83 ± 0.45 ) × 107/L in the incomplete KD group,which showed no significant difference between the two groups ( t =1.86,P ＞ 0.05 ).CondusionCEC level was elevated significantly in the acute phase of KD.The CEC level in CAL group was higher than that of NCAL group in acute phase.CEC level detection may be helpful for the early diagnosis of KD.

Objective To analyze the incidence of the disease, clinical features, diagnostic criteria, therapy and prognosis of Penicilliosis marneffei found in Guangdong province. Methods To analyze patients data, clinical features, laboratory findings, response to therapy, and prognosis of 15 cases Penicilliosis marneffei found in Guangdong province of China. Results The male was predominant compared with the female (ratio 2 to 1) and without occupational preference, but the patients with AIDS as underlying disease were mostly drivers and the unemployed. Thirteen patients were immunocompromised such as AIDS, connective tissue disease, and kidney transplant. Clinical features showed different manifestations, such as high fever, loss of weight, skin lesion, and respiratory system symptoms. Biopsy of the skin lesion showed PAS stain positive yeast-like, or sausage-form spores. Four patients were localized infection of the skin, eleven patients were systemic infection. Nine patients died, five recovered, 1 patient refused to be treated. Fifteen isolates from different anatomic sites of the patients were identified to be Penicillium marneffei by morphology and dimorphism in the culture, and eleven isolates among these 15 isolates were also confirmed by DNA sequence analysis. Conclusion The incidence rate of Penicilliosis marneffei become higher in the recent years and many patients were accompanied with AIDS in Guangdong province. Attention should be paid to the disease.

Objective To retrospectively analyze whether the kyphosis exists after removal of the internal fixators for thoracolumabar vertebrae fractures. Methods A total of 18 patients (35-68 years old) with thoracolumabar vertebrae fractures (T11-L2 ) were fixed with short segment pedical screw. The fixators were removed one year postoperatively to observe the changes of the Cobb' s angle and trauma vertebra'height. Results All the patients were followed up for 6-24 months ( average 18.7 months),which showed no intraoperative or postoperative complication, breakage or loosening of the screws. Compared to the Cobb angle and the vertebra height before removal of the internal fixators, the average loss of the Cobb angle was 0.7° and that of the vertebra height was 0.8 mm six months after removal of the fixators, 1.9° and 1.1 mm respectively one year after removal of the fixators, and 2.4° and 1.3 mm respectively two years after removal of the fixators in 16 patients without osteoporosis (P ＞0. 05). Among two patients with osteoporosis, the average loss of the Cobb angle and the vertebra height was 6° and 8°respectively and 3 mm and 5 mm respectively six months after removal of the fixators; 13° and 17° respectively and 5 mm and 7 mm respectively one year after removal of the fixators; 15° and 19° respectively and 6 mm and 7.5 mm two years after removal of the fixators. Conclusions After the internal fixation for thoracolumbar vertebrae burst fractures, kyphosis develops mildly, with insignificant change of the vertebral height. While the kyphosis becomes worse after removal of the fixators for thoracolumbar vertebrae burst fractures in patients with osteoporosis.

BACKGROUND:Percutaneous injection of bone cement into the vertebral body can enhance the vertebral strength and vertebral stability, and obtain pain relief. But the bone cement may leakage into the paravertebral vessels during injection, and may back to the right ventricle and flow into the pulmonary artery through vena cave and thus causing pulmonary embolism.
OBJECTIVE:To evaluate the relationship between cement paravertebral vascular leakage and pulmonary cement embolism during percutaneous vertebroplasty.
METHODS:Total y 134 cases of osteoporotic compression fractures treated with vertebroplasty were retrospectively analyzed. Among them, 23 cases of cement paravertebral vascular leakage were considered as the experimental group, and the 43 cases without cement paravertebral vascular leakage and had the complete imaging data were considered as the control group. The spine and chest X-ray films were taken before and after vertebroplasty to detect whether there were cement paravertebral vascular leakage and pulmonary cement embolism in the patients of two groups.
RESULTS AND CONCLUSION:Among the 134 patients, 23 patients had cement paravertebral vascular leakage, and accounted for 17.2%. Among the 23 patients with cement paravertebral vascular leakage, three cases had pulmonary cement embolism without chest symptoms, and accounted for 13%. No pulmonary cement embolism occurred in the 43 patients without paravertebral vascular leakage of the control group, and there was no significant difference between two groups (P=0.039). Although the patients with cement pulmonary embolism remained asymptomatic, pulmonary cement embolism remained possible if cement paravertebral vascular leakage was detected during vertebroplasty.

Objective To evaluate the treatment effect and security of transcatheter arterial chemoembolization(TACE)combined with sorafinib for intermediate-advanced hepatocellular carcinoma.Methods From July 2008 to November 2010,the treatment effects of two groups of patients with advanced hepatocellular carcinoma were retrospectively analyzed and compared,including 44 patients treated by sorafenib combined with TACE(test group)and the other 44 patients treated only with TACE(control group).To assess the treatment effect based on mRECIST,the time for patients' tumor progression(TTP),overall survival(OS)time and adverse events were recorded.Survival rate were analyzed using KaplanMeier method and Log-rank analysis in SPSS 18.0.Results Till January 2011,24 patients(54.5％)survived and 20 patients(include patients lost to visit)died(45.5％)among the test group,13 patients survived(29.5 ％)and 31 patients(include patients lost to visit)died(70.5 ％)among the control group.No complete remission condition was observed in all patients.Among the test group,1 patient got partial remission,24 ones remain stable and 19 patients got progression.While among the control group,conditions remained stable in 21 patients and progressed in rest 23 ones.The disease control rate(DCR)in the test group and control group were 56.8％(25/44)and 47.7％(21/44)respectively,with no statistical significance(x2 =0.729,P =0.393).The median overall survival time(mOS)of test group and control group were 21.0(95 ％ CI:14.9-27.1)months and 10.0(95 ％ CI:6.4-13.6)months respectively,and the difference reached statistical significance(x2 =7.436,P =0.006).The median time to tumor progression(mTTP)of test group and control group was 1 1.0(95％ CI:8.7-13.3)and 6.0(95％ CI:3.9-8.1)months respectively,and the difference had statistical significance(x2 =10.437,P =0.001).The adverse events of test group mainly included hand-foot skin reaction,loss of appetite,fever,fatigue and diarrhea.The adverse events of control group mainly included fever,loss of appetite,nausea,vomiting and fatigue.The incidences of hand-foot skin reaction,baldness,diarrhea were significantly higher in test group than those in the control group(P ＜0.05).In most patients,these side effects were mild-to-moderate,and alleviated remarkablely after symptomatic treatment.Conclusions Compared with TACE alone,TACE combined with sorafenib can prolong the OS and TTP significantly for the patients with intermediate-advanced hepatocellular carcinoma.However,the DCR of the two groups has no statistical significance.

ObjectiveTo analyze the influencing factors and clinical results of radial shortening after operation of intra-articular fractures. MethodsA total of 54 patients with intra-articular fractures of the distal radius treated surgically from January 2003 to January 2008 were followed up and divided into radial shortening group ( ＞ 4 mm) and control group ( ＜ 4 mm) by whether radial shortening was more than 4 mm. Fracture types, comminution and defection degree, age, surgical approach and internal fixation method, whether bone implant in operation, post-operative volar tilting angle and ulnar inclination angle, and wrist function score were investigated and compared between the two groups. ResultsThe incidence of radial shortening in post-operation of intra-articular fractures of the distal radius was 30％.Age and whether bone implant in operation were significantly different between the two groups. Type C fractures were more liable to radial shortening than type B fractures. Operation approach and internal fixation method have no significant influence on the radial shortening. Volar tilting angle and ulnar inclination angle were not significantly different between the two groups and the excellent and good rate of function score was lower in the radial shortening group. ConclusionThere is a high incidence of radial shortening after operation for the intra-articular fractures of the distal radius, which affects the clinical results of operation. Therefore, we should pay more attention to the influencing factors and take corresponding precaution methods during operation.

Kawasaki disease is far more frequent in children than in adults. The pathogenesis of Kawasaki disease is unknown, but it involves changes to the coronary artery and other diverse clinical manifestations. There are currently no specific laboratory diagnostic indexes, and especially since the disease is rare in adults, so it is extremely easy to misdiagnose or to overlook entirely. Our retrospective analysis of an diagnosis of and treatment for Kawasaki disease in an adult provides a guide to clinical doctors in terms of understanding Kawasaki disease, early diagnosis of it, and improved prognosis.

Objective:To assess antimicrobial activity of Fe 3O 4 nanozymes against Candida albicans. Methods:Fe 3O 4 nanozymes were prepared by using a modified hydrothermal synthesis method. Candida albicans suspensions were divided into 4 groups: nanozyme group treated with 0.5 g/L Fe 3O 4 nanozymes, H 2O 2 group treated with 0.1% H 2O 2, combination group treated with 0.5 g/L Fe 3O 4 nanozymes and 0.1% H 2O 2, and control group receiving no treatment. Candida albicans in the above 4 groups was all cultured with Sabouraud liquid medium, the absorbance value at 600 nm was detected every 2 hours, and the growth of Candida albicans was observed. After 2-hour treatment, the morphology of Candida albicans in the 4 groups was observed by scanning electron microscopy; after plate coating, Candida albicans was cultured at 36 ℃ for 48 hours, colonies were observed and counted, and the inhibition rate of colony formation was calculated. One-way analysis of variance was used for comparing means among several groups, and least significant difference (LSD) - t test for multiple comparisons. Results:A relatively stable survival curve of Candida albicans was observed in the control group, while the growth of Candida albicans was inhibited in the nanozyme group, H 2O 2 group and combination group. The colony count significantly differed among the control group, H 2O 2 group, nanozyme group and combination group (124 830 ± 45 170, 86 330 ± 13 960, 91 670 ± 31 370 and 30 330 ± 3010 respectively; F = 9.41, P < 0.05) , and was significantly lower in the combination group than in the control group ( t = 4.63, P < 0.05) . There was a significant difference in the colony-formation inhibition rate among the H 2O 2 group, nanozyme group and combination group (30.84% ± 5.00%, 26.57% ± 11.24%, 75.70% ± 2.42% respectively; F = 9.413, P < 0.01) , and the combination group showed a significantly higher inhibition rate compared with the H 2O 2 group and nanozyme group ( t = 8.08, 4.27 respectively, both P < 0.01) . Scanning electron microscopy showed changes in the morphology of Candida albicans treated with H 2O 2 and nanozymes alone or in combination, including shrinkage, rupture and even collapse. Conclusion:Fe 3O 4 nanozymes combined with H 2O 2 have obvious antimicrobial effect against Candida albicans.

We report a case of cutaneous and subcutaneous phaeohyphomycosis caused by Exophiala jeanselmei after renal transplantation in Guangdong. A 66-year-old man who had a renal transplantation 6 years ago was admitted in October 2011 for the presence of 16 nodules (0.5-1.5 cm) found on his right middle finger, wrist and forearm for 5 months. Microscopic examination of the purulent exudate showed segmented and branched brown mycelium, and tissue biopsy and PAS staining showed fungal hyphae. The isolate was processed for morphological identification and molecular sequence analysis. A black colony was found after culture of the isolate on SDA at 26 degrees Celsius;, and small culture identified the isolate as Exophiala jeanselmei. ITS sequence analysis of the isolate showed a 100% homology with Exophiala jeanselmei. E-test strip was used in drug sensitivity test, and the isolate was sensitive to amphotericin B, voriconazole, itraconazole and fluconazole, but resistant to 5-flucytosine and caspofungin. Good response was obtained with surgical intervention, local injection and systemic antifungal treatment.
