Objective To evaluate the role of clinical features,radiography and histopathology in differential diagnosis between chronic necrotizing pulmonary aspergillosis(CNPA)and aspergilloma.Methods Thirty-four patients including 8 cases of CNPA and 26 of aspergilloma comfirmed by operation and histopathology in First Affiliated Hospital,Zhejiang University were investigated retrospectively.The clinical manifestations,radiological and pathological findings of all the patients were analyzed and related references were reviewed. Results The age of onset was not significantly different between CNPA and aspergilloma.Obsolete pulmonary tuberculosis and lung abscess were predisposing factors of them.Productive cough was presented in all 8 cases of CNPA,haemoptvsis in 7,and 5 were presented with constitutional symptoms.The most common symptom of aspergilloma was haemoptysis, which was presented in 25 cases.The less common symptoms were cough and sputum,which was presented in 17 cases.Only two cases were presented with constitutional symptoms."Air crescent"sign at radiography was typical and suggestive of diagnosis in both CNPA and aspergilloma,but the wall of cavity in CNPA was thicker and irregular,infiltrates were often to be seen around the cavity.Histologically,CNPA and aspergilloma both showed septate fungal hyphae branching at an acute angle.CNPA was characterized with the presence of tissue invasion by aspergillus,tissue necrosis and granulomatous inflammation. Fungal hyphae ware only found in a preexistent cavity or ectatic bronchus without tissue invasion in aspergilloma.Conclusions Histopathology is gold standard of differential diagnosis of CNPA and aspergilloma. Meanwhile, clinical features and radiological findings appear to be valuable for the diagnosis.

We developed a rehabilitation system by using the virtual reality technique and the Kinect in this paper. The system combines rehabilitation training with HMI and serious game organically, and provides a game and motion database to meet different patients' demands. Extended interface of game database is provided in two ways: personalized games can be developed by Virtools and Flash games which are suitable for patients' rehabilitation can be download from the Internet directly. In addition, the system provides patients with flexible interaction and easy control mode, and also presents real time data recording. An objective and subjective evaluation method is proposed to review the effectiveness of the rehabilitation training. According to the results of short questionnaires and the evaluation results of patients' rehabilitation training, the system compared with traditional rehabilitation can record and analyze the training data, which is useful to make rehabilitation plans. More entertainment and lower cost will increase patients' motivation, which helps to increase the rehabilitation effectiveness.

Objective Calreticulin (CRT)is a multifunctional protein of endoplasmic reticulum implicated in the pathogenesis of rheumatoid arthritis(RA). The present study was undertaken to determine whether CRT was involved in an?giogenesis events in RA. Methods Serum CRT levels were measured by enzyme-linked immnuosorbent assay(ELISA)in 106 patients with established RA, 75 osteoarthritis(OA)and 80 healthy controls(HC). CRT levels in synovial fluid were al?so measured in 25 RA and 22 OA patients. The expression of CRT in synovial tissue was examined by immunohistology. In order to investigate the role of CRT on angiogenesis, human umbilical vein endothelial cells(HUVECs)were isolated and cultured for in vitro experiments. The proliferation, migration and tube formation of HUVECs following CRT stimulation were examined in vitro by MTT assay, scratch wound healing assay and tube formation assay. Results Our results showed a sig?nificantly higher concentration of CRT in serum [(6.4±3.1) μg/L] of RA patients compared to that of OA [(3.7±0.9) μg/L, P<0.01] and HC [(3.4±1.0) μg/L, P<0.01];and significantly higher CRT in synovial fluid [(6.9±3.4) μg/L] of RA vs OA [(3.9± 0.7) μg/L, P<0.01]. Increased CRT expression predominantly localized to vascular endothelial cells, inflammatory cells and perivascular areas in both the lining and sublining layers of RA synovial tissue. Furthermore, CRT significantly promoted the proliferation, migration and tube formation of HUVECs, as showed by MTT assay, scratch wound healing assay and tube for?mation assay. Conclusion These findings suggested that CRT may be involved in synovitis and pannus formation events via promoting angiogenesis in RA.

OBJECTIVETo discuss the hemostasis of the different polarities of Platycladi Cacumen Carbonisatum (PCC) on the blood heat and hemorrhage syndrome rat model induced by dry yeast.
METHODThe SD rats were divided into seven groups. Yunnan Baiyao was taken as the positive control drug. The rats in the control group and model group were fed with CMC-Na for 7 days, and the rats in other groups were fed with corresponding drugs simultaneously. On day 7, the blood heat and hemorrhage syndrome rat model was established. Indexes including the whole blood viscosity, plasma viscosity, thrombin time (TT), activated partial thromboplastin time (APTT), prothrombin time (PT), fibrinogen content (FIB), red blood cell (RBC), hemoglobin (HGB), hematocrit (HCT), blood platelet count (PLT), thrombocytocrit (PCT), mean platelet volume (MPV), platelet distribution width (PDW) and the rate of platelet aggregation induced by ADP were detected. Additionally, the pathological examinations of lungs among each group were compared.
RESULTCompared with the control group, the RBC, HGB and HCT of rats in the model group increased significantly, with distinct increase in high, middle and low whole blood viscosity and plasma viscosity of rats in the model group; TT and APTT were notably prolonged, while PT was notably shortened, with significant increase in FIB content; PLT, PCT, MPV and PDW remarkably increased; Additionally, the rate of platelet aggregation induced by ADP significantly decreased. After ig administration of the ethyl acetate extract of PCC, the low whole blood viscosity and plasma viscosity remarkably decreased; TT and APTT were significantly shortened, with notable reduction in PDW and in FIB content Additionally, the rate of platelet aggregation induced by ADP significantly increased. The injury of lungs was also improved in ethyl acetate extract group. The rate of platelet aggregation induced by ADP of n-butanol extract group notablly increased. Plasma viscosity of water extract group remarkably decreased, with TT being significantly shortened. But the effects of n-butanol extract or water extract were weaker than that of ethyl acetate extract. And the effect of petroleum ether extract was the weakest.
CONCLUSIONEthyl acetate extract is the active part of PCC, showing the effect of hemostasis by reducing the low whole blood and plasma viscosity, improving coagulation function mainly by acting on the endogenous coagulation, and ameliorating the function of platelet aggregation.

Objective To study the association of MIF-173 locus polymorphism and the risk of prostate cancer (PCa) in China. Methods A case control study including 259 PCa patients and 301 age-matched controls was conducted. The polymorphisms of MIF-173 locus were analyzed by poly-merase chain reaction restriction fragment length polymorphism (PCR-RFLP) technique using genomic DNA isolated from peripheral blood lymphocytes. The correlations between the susceptibility to PCa and different genotypes were compared. The effect of age, smoking method and family history of canc-er were also analyzed. Results The rate of the MIF-173 * C variant allele of the PCa patients(n=259) was significantly higher than that of the controls (n=301) (36.0% vs 15.0%). The MIF-173 *C variant allele could significantly increase the risk of PCa (OR=2.96,95%CI: 1.92-4.57). Peo-ple with older age (age>70) or family history of cancer, who carried MIF-173 * C allele demonstra-ted a significantly increased risk in comparison with those carrying wild genotype of G/G(OR=3.66, 95%CI=2.02-6.62;OR=3.26, 95%CI=1.24-8.55). Conclusion These results suggested that polymorphisms of MIF-173 locus appear to influence the risk of PCa and may have synergistic effect with age and family history of cancer.

Objective To compare the clinical efficacy and safety of isotretinoin erythromycin gel, a gel containing isotretinoin (0.05%) and erythromycin (2%), versus adapalene gel in the treatment of mild to moderate acne vulgaris. Methods A multicenter, randomized, open, parallel-controlled clinical study was conducted. A total of 192 patients with mild to moderate (Grade Ⅰ -Ⅲ ) acne vulgaris were enrolled in this study according to the grading criteria for acne severity in guidelines for the treatment of acne in China. Efficacy analysis was carried out in 169 patients and safety analysis in 190 patients. The patients were classified into trial group (n = 86) and control group (n = 83 ) to be treated with isotretinoin erythromycin gel or adapalene gel once a night for 6 weeks. Patients were evaluated at the baseline, on week 2, 4 and 6 during the treatment for the count of comedones (both open and closed), inflammatory papules and pustules, severity of acne and local or general adverse effects. Results After the start of treatment, the response rate gradually increased and severity of acne decreased in both groups. On week 6, the total response rate was 51.16% in the trial group and 40.96% in the control group (P > 0.05), while a greater reduction in the count of pustules and inflammatory lesions was observed on week 4 and 6 in the trial group with a lower severity grade of acne compared with the control group (P < 0.05 or 0.01 ). Adverse reactions were similar in both groups and manifested as tolerable local irritation. Conclusions The efficacy of isotretinoin erythromycin gel is similar to that of adapalene gel in the treatment of mild to moderate acne vulgaris, however, isotretinoin erythromycin gel seems superior to adapalene gel in reducing inflammatory lesions and rapidly improving severity of acne vulgaris.
