Objective To investigate the effect of depression on the incidence of osteoporosis in patients with maintenance peritoneal dialysis (MPD).Methods We enrolled 80 MPD patients,who underwent peritoneal dialysis in our dialysis center.The clinical data and biochemical parameters of all patients were collected,bone mineral density was detected and the Self-rating depression scale was used to evaluate depression state.Results Among the 80 enrolled MPD patients,34 patients had osteoporosis (42.5％),48 patients had the presence of depression (60％).Logistic regression analysis showed that age,dialysis age,gender,diabetes history and depression state were the risk factors for osteoporosis in MPD patients,the depression state was negatively correlated with BMD of lumbar and femoral neck (r=-0.347,r=0.426,P＜0.05).Conclusion Depression state may be a risk factor for osteoporosis in clinic,it is of great significance to focus on the psychological state of MPD patients in the prevention and treatment of osteoporosis.

Abstract? AIM: To analyze the ocular manifestations of meningiomas in the trigone of the lateral ventricle, discuss the relevant factors of visual impairment in these patients and things need attention clinically.?METHODS:Retrospectively study on the clinical data of 90 eyes in 45 patients diagnosed of trigonal meningiomas treated at Beijing Tian Tan Hospital from October 2011 to October 2015.Preoperative examinations including visual acuity, optic disc findings, visual field, size of tumors and other change in MRI were analyzed.?RESULTS: Patients'age was 12-68 years old ( mean 41.7 ±13.7 years ). Male/female ratio was 1 ∶4.6. Decreased visual acuity occurred in 18 eyes.Optic disc edema was found in 24 eyes and optic disc pale in 6 eyes. Fourty -seven eyes had visual field defect, mostly homonymous hemianopia or defect. The maximum diameter of tumors was 2.1-9.6cm (4.8±1.7cm).Range of tumor volume was 3.02-193.2cm3(48.3±47.8cm3).A positive correlation of preoperative visual field defect was found with tumor volume, tumor maximum diameter, and brain midline shift respectively. While the preoperative visual field defect was not found any correlation with age, gender, course, and the enlargement of the ventricle and the edema of the tissue around the tumors. After Mann-Whitney U test, the differences on tumor volume, the maximum diameter of tumors, and brain midline shift between the two groups were significant.? CONCLUSION: Patients with trigonal meningiomas often have ocular signs and symptoms.The major reason of visual field defect is the damage of optic radiation around the tumor.The specific position of injured optic radiation determines the type and extent of visual field defect.Both ophthalmologist and neurosurgeon should pay attention to tumors nearby posterior visual pathway. Doing neurophthalmology examinations for these patients and realizing the position between the tumor and posterior visual pathway will be helpful and necessary in surgical planning.

Objective To understand the microorganisms pollution and the community structure and distribution characteristics of airborne microbes in forest scenic spot in Huangshan,China.Methods The airborne microbes were sampled by fallen plate method from 2002 to 2003 in Huangshan scenic area and Hefei city.Results The results showed that there was a significant negative correlation between the elevation and airborne microbe,the relative coefficient was -0.580(P

Objective: To explore the application of18F-lfuorodeoxyglucose (FDG) micro- positron emission tomography (PET) myocardial metabolism imaging for evaluating dilated cardiomyopathy model (DCM) in experimental rats. Methods: A total of 12 male SD rats were randomly divided into 2 groups: DCM group, the rats received intraperitoneal injection of adriamycin at 1.0 mg/kg twice per week and Control group, the rats received intraperitoneal injection of normal saline, all animals were treated for 6 weeks followed by 2 weeks observation.n=6 in each group. Echocardiography was performed at pre- and post-modeling,18F-FDG micro-PET myocardial metabolism imaging was conducted after modeling and plasma level of BNP was examined as well. Finally, the rats were scariifed to observe the pathological changes of myocardial tissue. Results: 1 rat died in DCM group and the rest were with successful modeling conifrmed by echocardiography and pathology. Compared with Control group, DCM group showed decreased standard uptake value of18F-FDG (1.23 ± 0.55) vs (6.65 ± 0.41),P<0.01; the standard uptake value of18F-FDG was negatively related to left ventricular end diastolic diameter (LVEDD) (R=-0.709,P=0.015), LVESD (R=-0.924, P=0.000) and plasma level of BNP (R=-0.948,P=0.000), while positively related to LVEF (R=0.968,P=0.000) and fractional shortening (R=0.863,P=0.001). Conclusion:18F-FDG micro-PET myocardial metabolism imaging combining echocardiography, biochemical and pathological examinations may evaluate DCM modeling in rats, which provide a non-invasive and intravital tool for small animal experiment.

OBJECTIVETo study whether co-stimulatory molecule CD40 of alveolar macrophage (AM) participated in the occurrence and development of silicosis, and to explore the intervention of Yiqi Huoxue Decoction (YHD) in the fibrosis of silicosis patients.

METHODSTotally 46 silicosis inpatients and outpatients were recruited and randomly assigned to the Western treatment group (A) and the Chinese medicine (CM) treatment group (B), 23 in each group. Patients in Group A received routine symptomatic treatment such as anti-inflammation, phlegm resolving, anti-spasm, and asthma relief, and so on. Patients in Group B additionally took YHD, one dose daily for 14 successive days. Besides, another 18 patients with chronic cough and sense of laryngeal foreign bodies were recruited as the normal control group, who had no obvious lesion confirmed by bronchofi6roscope and clinical diagnosis of the lung. They were treated by symptomatic supporting treatment. The alveolar lavage fluid was collected from all patients and isolated, and AM cells were cultured. The level of CD40 mRNA was detected by RT-PCR. The expression of CD40 protein was detected by Western blot.

RESULTSCompared with the normal control group, expression levels of CD40 mRNA and CD40 protein significantly increased in Group A (P < 0.01). Compared with Group A, expression levels of CD40 mRNA and CD40 protein significantly decreased in Group B (P < 0.01).

CONCLUSIONSHighly expressed co-stimulatory molecule CD40 of AM might participate in pulmonary fibrosis. YHD could hinder its roles, inhibit the progression of fibrosis, thereby playing an interventional role of treatment.

OBJECTIVETo study the correlation of G870A CCND1 gene polymorphism and digestive system tumors.

METHODSFrom August 2010 to August 2014, 164 digestive system cancer patients (including 82 patients with gastric cancer and 82 with colorectal cancer) and 82 healthy subjects (control group) were examined with PCR-restriction fragment length polymorphism (PCR-RFLP). The distribution of CCND1 gene G870A frequency in the 3 groups and its association with tumor staging and grading were analyzed.

RESULTSThe frequencies of the GG, GA and AA genotypes in G870A CCND1 gene loci in patients with gastric cancer and colorectal cancer differed significantly from those in the control group (P<0.05). G870A CCND1 gene polymorphism was closely associated with an increased risk of digestive system tumors (P<0.05). The GA and AA genotypes were associated with a significantly higher risk of digestive system cancer risk than the GG genotype (P<0.05), and their frequencies were significantly higher in patients with tumors of higher pathological grade and in those in advanced tumor stages (P<0.05).

CONCLUSIONG870A CCND1 gene polymorphism is associated with the risk of digestive system tumors. The allele A is associated with an increased risk of digestive system tumors and correlated with the tumor differentiation and staging of the tumor.
