OBJECTIVE: To study the clinical feature and treatment of extracranial and intracranial complications caused by otitis media. METHOD: Three hundred and twenty patients of acute and chronic otitis media were admitted to our department between 2005 and 2014. Among them, 34 patients were diagnosed with extracranial and intracranial complications. The clinical features and treatment outcome were retrospectively studied. Of the 34 patients associated with complications, 25 had a single complication,8 had two complications and 1 had three complications. Complications included labyrinthitis in 14 cases, facial paralysis in 11, postauricular subperiosteal abscess in 6, Bezold abscess in 1, thrombophlebitis of sigmoid sinus in 2, otitis meningitis in land otogenic brain abscess in 8. RESULT: Thirty-three patients were cured or improved and 1 patient died. CONCLUSION Due to the widespread use of antibiotics, the clinical manifestations of extracranial and intracranial complications of otitis media become more hidden and atypical. The surgery is the primary treatment method.

ObjectiveTo understand the clinical and microbiological characteristics of AIDS-associated bloodstream infection (BSI).MethodsThe clinical and laboratory ifndings of 143 cases of BSI in AIDS patients who were hospitalized during the period from 2013 to 2014 were retrospectively analyzed.ResultsThe prevalence of BSI in AIDS patients was 22.1%. The 143 patients were divided into two groups in terms of fungal or bacterial infection. The incidence of speciifc skin rashes, anemia, hepatosplenomegaly and lymph node enlargement in fungal infection group was higher than those in bacterial infection group (allP<0.05). CD4+ cell count, WBC, neutrophils, RBC, hemoglobin, and platelet count in fungal infection group were lower than those in bacterial infection group, while AST and Cr were the opposite (allP<0.05).Penicillium marneffei(84/143, 58.7%) was the most common pathogen isolated from AIDS-associated BSI, followed byEscherichia coli (10/143, 7.0%),Cryptococcus neoformans (9/143, 6.3%),Klebsiella pneumoniae (7/143, 4.9%),Salmonella (6/143, 4.2%),Candida albicans(3/143, 2.1%), andAeromonas (3/143, 2.1%). Most strains were still susceptible to the commonly used antibiotics.ConclusionsThe prevalence of BSI is high in AIDS patients. Fungal BSI is more likely to have skin rash, anemia, hepatosplenomegaly and lymphadenopathy, hematologic abnormalities, liver and renal function impairment. Fungi, especiallyPenicillium marneffei, are the main pathogen of AIDS-associated BSI. Most strains are susceptible to the commonly used antibiotics.

Objective To investigate the influence of telephone follow-ups on the compliance of syphilis patients.Methods The 120 patients diagnosed with syphilis during February 2010 to December 2011 were randomly divided into experiment group and control group with 60 cases in each group.The control group was given disease-related education during outpatient visits,while the experimental group received nursing intervention by phone calls.The two groups were compared in respect of curative compliance. Result The curative compliance of the experiment group after follow-ups was significantly better than that of the control group (P<0.01).Conclusion The telephone follow-ups can significantly improve the curative compliance of syphilis patients,which can significantly prevent the spread of syphilis.

Objective To determine the relationship between cigarette smoking and the incidence of systemic lupus erythematosus.Methods Database including Cochrane Library,Pubmed,OVID and Elsevier were electronically searched to collect case-control and cohort studies on the relationship between cigarette smoking and incidence of systemic lupus erythematosus.The literatures were screened and the data were extracted independently according to the inclusion and exclusion criteria.The quantitative analysis were performed by using Stata 12.0 software.Results The pooled OR values (95％ confidence interval)of current smoking and ever smoking were 1.82 (95％CI 1.42～2.34) and 1.22 (95％CI 0.96～1.56) respectively.Conclusions Our Meta-analysis revealed a moderate but statistically significant association between current smoking and development of systemic lupus erythematosus.However,it is still not confirmed whether the past smoking is one of the risk factors of systemic lupus erythematosus.

OBJECTIVE: To explore the severity index of Meniere's disease during acute phase by a statistical method of principal component analysis (PCA). METHOD: Ninety-five patients with Meniere's disease in the acute phase who saw the doctor with 24 hours after onset were included in this study and their clinical data were analyzed retrospectively. The subjective symptoms of hearing loss (X1) and ear stuffy plug (X4) were evaluated by VAS scoring system, and the impact of vertigo (X2) and tinnitus (X3) on the patients were evaluated by DHI and THI score. The principal component analysis (PCA) method was used to analyze the quantified data and construct a synthetic evaluate function of subjective symptoms. RESULT: (1) The quantitative results of subjective symptoms in patients with Meniere's disease were as follow: VAS score (X1) of hearing loss was 0-91 points, with an average of 46.23 ± 18.80, DHI score (X2) of vertigo was 8-98 points, with an average of 49.66 ± 15.67, THI score (X3) of tinnitus was 10-100 points, with an average of 47.53 ± 17.44, and ear VAS score (X4) of stuffy plug feeling was 0-82 points, with an average of 21.55 ± 27.54. (2) The eigenvalue of principal components Z1, Z2 and Z3 were 1.876, 0.984 and 0.703 respectively, and the variance contribution were 46.898%, 24.592% and 17.574% respectively. (3) The constructed synthetic evaluate function of the disease was as follow: The Meniere's disease severity index ƒ = 0.213ZX1 + 0.398ZX2 + 0.370ZX3 + 0.455ZX4. CONCLUSION The method of PCA for the subjective evaluation of symptoms in Meniere's disease can be constructed as a model of comprehensive evaluation system, which may provide relatively comprehensive information of clinical original variables included in the four main symptoms, reflecting the severity of the disease.

Objectiv e:To investigate the effect of different culture conditions on the differentiation of Treg and Th17 to lay a foundation for exploring the methods to reverse the immune tolerance induced by tumor microenvironment.Methods:The IL-6 gene was cloned and stablely transferred into the tumor cell line expressing TGF-β.The conditioned mediums ( CM) were prepared by collecting the culture supernatants of tumor cell lines with or without IL-6 expression and used in the in vitro culture of peripheral blood mononuclear cells ( PBMC ) .The changes of Treg and Th17 in PBMC treated with different CM were detected with flow cytometry ( FCM) .Results:The expression of TGF-βin BEL-7402 was higher than that in HepG2.Thus the BEL-7402 was selected for preparation of cell line stablely transfected with IL -6 gene.ELISA detection confirmed the effective expression of IL -6 by the identified cell lines.It was showed that the Treg increased in PBMC treated with culture supernatants of tumor cells .However,the presence of IL-6 reversed the increase of Treg and promoted the differentiation of Th 17.Conclusion: The culture supernatants of tumor cells increases the proportion of Treg.However,the presence of IL-6 in this CM can reverse the increase of Treg and raise the proportion of Th 17.

Objective To explore the risk factors for patients with massive hemoptysis in tuberculosis and to provide a strategy for clinical treatment for tuberculosis massive hemoptysis (TMH). Methods Chi-square test and multivariate logistics analysis were applied to analyze the medical data of 241 cases of TMH. Results Chi-squared test showed that eleven factors were found to be significantly correlated with TMH. Longer disease course (≥3 months), lung lesions range ≥ 3 lung fields, pulmonary tuberculosis cavity, a higher smoking index (≥400 cigarettes per year) and clinical treatment were risk factors for TMH. Patients aged 45 years or older accompanied with bronchiectasia, pulmonary fungal infection, diabetes or hepatopathy had higher probabilities of developing massive hemoptysis. Multivariate analysis showed lung lesions range over 3 lung fields (OR = 2.447,P = 0.015), pulmonary tuberculosis cavity (OR = 2.486, P = 0.004), bronchial asthma (OR =3.192,P = 0.002), pulmonary fungal infection (OR = 3.896, P = 0.005) and hepatopathy (OR = 3.101, P =0.006) were final risk factors for TMH. Conclusion Multiple factors contributed to patients with massive hemoptysis in tuberculosis. Lung lesions range over 3 lung fields, pulmonary tuberculous cavities, bronchial asthma, lung fungal infection and hepatopathy might be the independent risk factors for TMH.

Objective To explore the effect of the Internet technology′s application on the hand hygiene compliance of medical staff. Methods Establishing Internet+hand hygiene management model to implement Internet based hand hygiene supervisory and reminding, Internet based hand hygiene publicity and education, and Internet based hand hygiene feedback and communication. This model was applied in Guangdong Provincial Dermatology Hospital to intervene the hand hygiene related activities. Before and after the intervention, the hand hygiene compliance of medical staff in the trial hospital was observed with WHO hand hygiene monitoring table by directly manual observation. Thereafter, the changes of hand hygiene compliance before and after the intervention were compared based on the statistical analysis of test results. Results With the application of Internet+hand hygiene management model, the hand hygiene compliance of medical staff increased from 41.75% (324/776) before the intervention to 72.14% (554/768) after the intervention, and the difference was statistically significant (χ2=145.264, P<0.01). The hand hygiene compliance of both doctors and nurses was significantly increased (doctors: χ2=94.784, P<0.01;nurses:χ2=58.798, P<0.01). In all the five indications, i.e., before patient care, before an aseptic task, after exposure to blood/body fluids, after patient care, and after environmental contact, the hand hygiene compliance was 35.42%(68/192), 63.33%(38/60), 84.38%(54/64), 44.83%(130/290), and 20.00%(34/170) respectively before the intervention;it was 65.38%(102/156), 83.33%(120/144), 95.45%(105/110), 68.52%(148/216), and 55.63%(79/142) after the intervention; and the difference before and after the intervention was statistically significant (χ2=6.305-42.529;P<0.01 or 0.05). Most of the medical staff of the trial department supported this model. Conclusions Internet+ hand hygiene management model could significantly improve the hand hygiene compliance of medical staff and were very popular. And, the model is worth of application in more hospitals.

Objective RNPC1 may act as an oncogene or suppressor gene in human tumors and its role in human renal cell carcinoma (RCC) remains unclear.The objective of this study was to investigate the role of RNPC1 in the development of RCC.Methods Over-expression of RNPC1 gene group (RNPC1 group) and short hairpin RNA interfering RNPC1 gene expression (shRNPC1 group) were respectively built in RCC CAKI-1 and CAKI-2.The blank control group (NC group) and negative control group (SCR group) were built as well.The qRT-PCR and western blot (WB) were used to detect the expression levels of RNPC1 mRNA and RNPC1 protein in RCC cells.Lentivirus infection was applied to establish stable expressed RCC cell lines of RNPC1 over-expression and interference.Detection was made on mRNA and protein expression levels in RNPC1 stable RCC cell lines.The effects of RNPC1 on cell proliferation, colony formation assay, migration, and invasion were detected by CCK-8 cell differentiation test, clone test, scratch test, and migration and invasion test.WB was applied to detect the change of protein expression in the EMT path of RNPC1 stable RCC cell lines and explore the molecular mechanism of RNPC1 effect on the biological function of RCC cells.Results The expression levels of RNPC1 mRNA and protein were found lower in shRNPC1 group than those in SCR group, while the expression levels of RNPC1 mRNA and protein in SCR group were higher than those NC group (P<0.05).The capability of proliferation in shRNPC1 group was stronger than that in SCR group, while the capability of proliferation in shRNPC1 group was weaker than that in NC group (P<0.05).The capabilities of cell migration and invasion were stronger in shRNPC1 group than those in SCR group, while the capabilities of cell migration and invasion in RNPC1 group were weaker than those in NC group (P<0.05).RNPC1 could inhibit the proliferation capability of RCC cells and might up-regulate the protein expression of E-cadherin and down-regulate the protein expression of β-catenin and vimentin, thus inhibiting EMT path and the capabilities of migration and invasion off RCC cells (P<0.05).Conclusion RNPC1 acts as a tumor suppressor in RCC and has the potential for the prediction of RCC prognosis.
