Two cases of chronic invasive fungal rhinosinusitis were reported. One patient healed while another died with suspicious residual fungal infection. The clinical symptoms of infratemporal fungal infection include maxillofacial pain, with or without fever. Acute or chronic inflammation of soft tissue could be revealed pathologically. Proof of pathogen may not be found in histopathological slice while serological detection may reveal positive evidence. Surgical resection, good drainage and postoperative antifungal therapy could cure or promptly relieve the symptoms of the disease.

Objective: By analyzing the relationship between the meteorological factors and the outbreak of emergencies, an artificial neutral network model was established in order to make the medical-meteorological forecast and to reduce and prevent the emergencies. Methods: The data of emergency cases and meteorological factors within the same time in 2007 and 2008 in Ji'nan, China were collected and analyzed by using SAS9.0. The back-propagation (BP) artificial neutral network model was built by using Matlab7.0. Results: A close relationship exists between the meteorological factors as well as their changes and emergencies. The results of forecast show high accuracy rate of each emergency (76% ～ 89%) except CO poisoning (46%). Conclusions: This emergencies medical-meteorological forecasting model based on BP neutral network has good prediction effect and the value of further research.

Objective To investigate the effect of intermedin (IMD) on tubular cells apoptosis induced by renal ischemia/reperfusion (I/R) injury and its associated mechanism.Methods A total of twenty-four male Wistar rats were randomly divided into four groups (control group, I/R group, empty plasmid group and IMD group). One week after the removal of right kidney, ultrasound plasmid was used to transfect empty or IMD plasmid into the left kidney. Renal I/R model was made by clasping the left renal artery for 45 minutes. Tubular cell apoptosis was determined by TUNEL. Expression of Bax, Bcl-2, Fas was detected by semi-quantitative RT-PCR.Activity of caspase-8 and caspase-9 was evaluated with commercially available kits respectively.Protein level of caspase-3 was measured by Western blotting analysis. Results Compared with control group, apoptosis of tubular epithelial cells, expression of Bax and Fas, activities of caspase-8 and caspase-9, as well as protein level of caspase-3 were all significantly increased in I/R group (all P＜0.05). IMD pre-treatment significantly inhibited all these effects (all P＜0.05). There were no differences of above parameters between empty plasmid group and I/R group. Conclusion IMD pre-treatment protects against renal I/R injury by inhibion of tubular epithelial cell apoptosis.

Objective To compare the clinical characteristics of community-acquired acute kidney injury (CA-AKI) and hospital-acquired acute kidney injury (HA-AKI) patients.Methods Hospital network system was employed to screen the clinical data of adult patients in the First Affiliated Hospital in Xinjiang Medical University in January to July 2013.A total of 19 528 patients were screened,and 544 AKI patients were identified based on KIDGO (Kidney Disease:Improving Global Outcomes) AKI guidelines.Three hundred and thirty patients were included in HA-AKI group and 214 patients in CA-AKI group.Clinical variables including mortality were analyzed retrospectively.Results The incidence of AKI in hospitalized patients was 2.8％ (544/19 528):1.7％ in CA-AKI group and 1.1％ in HA-AKI group.The mean age in CA-AKI group was significantly older than that in HA-AKI group [(62.9 ± 16.8) years vs (56.6± 15.9) years].Medical patients in CA-AKI group accounted for 62.4％,and surgical patients in HA-AKI group accounted for 64.1％.The co-morbid diseases were cardiac disease,hypertension,diabetes and chronic liver disease.Majority of AKI was caused by pre-renal etiologies.The length of hospitalization was significantly shorter in CA-AKI group compared to that in HA-AKI group [12(8,20) days vs 19 (12,27) days,P ＜ 0.01].Compared to that in HA-AKI group,all-cause mortality was significantly lower in CA-AKI group (11.5％ vs 20.1％,P=0.005).Results by multivariate logistic regression analysis demonstrated that the common independent risk factors of AKI in both groups were ICU hospitalization and shock.The independent risk factor of AKI in CA-AKI group was diabetes (OR=3.019).In contrary,the independent risk factors of AKI in HA-AKI group were elderly (≥65 years) (OR=3.303),oliguria (24 h urine volume ＜ 400 ml) (OR=6.906),use of antiinflammatory drugs (OR=13.079) and multiple organ dysfunction syndrome (OR=17.778).Conclusions The incidence of AKI in hospitalized patients is not rare,among which both communityacquired and hospital-acquired AKI are mainly caused by pre-renal etiologies.All-cause mortality is lower in community-acquired AKI compared to that in hospital-acquired AKI and the independent risk factors are different between CA-AKI and HA-AKI.

Objective To study the effect of allo-human bone marrow mesenchymal stem cells (BMSCs) on T and B cells from patients with Rheumatoid arthritis (RA) in vitro. Methods BMSCs were isolated from bone marrow samples of healthy volunteers and purified by density gradient centrifugation and cultured in vitro. Peripheral lymphocytes were isolated from patients with RA.Then, BMSCs and lymphpcutes were co-cultured. The modulatory effect of BMSCs on proliferation, activation and maturation of T and B lymphocytes of RA patients stimulated by PHA and SAC respectively was observed. The cell generation cycle and the degree of apoptosis were assessed by flow cytometry with PI/ Annexin V. After co-cultured with or without BMSCs for 72 hours, T cells were harvested, then they were labeled with anti-CD3, anti-CD4, anti-CD8, anti-CD25 antibodies and analyzed by flow cytometry. The density of IgG in the co-culture system was detected by ELISA. Results T and B cells proliferation was significantly suppressed when co-cuhured with bMSCs but did not induce T cell apoptosis. There was a significant decrease in the ratio of CD4+ CD3+ T cells in the co-cuhure group (34±6), as compared with the control group (44±7) (P<0.05). There was a decrease in CD25+ T cells and increase of CD4+ CD25+ cells in BMSCs co-cultured group (P<0.05). IgG was in creased in the cocuhure system. Conclusion Human BMSCs inhibit T and B cell activation and proliferation in patients with RA in vitro. And these immunomodulatory effects are not MHC restricted. The results of this study have provided evidence for the fact that BMSCs has the potential to be an effective treatment for RA.
