Objective:To study the correlation between hearing loss and cognitive decline in community-dwelling older adults and to analyze the influencing factors.Methods:Using Pure-tone audiometry, the Hearing Handicap Inventory for the Elderly (HHIE), Mini-Mental State Examination (MMSE), Patient Health Questionnaire-9 (PHQ-9), and Generalized Anxiety Disorder, a survey was conducted with 492 community-dwelling older adults aged 60 years and above in Beijing. Age, gender, education level, hearing loss, levels of anxiety and depression, and other factors were used as independent variables, and the MMSE scores were used as dependent variables. Analysis of variance and multiple linear regression were performed.Results:Among the 492 subjects, based on the better ears, 418 (85.0%) had hearing loss and 160 (32.5%) had disabled hearing loss. Factors such as age (β=-0.33, P<0.01), gender (β=0.09, P=0.04), education level (β=0.31, P<0.01), hearing loss (β=-0.11, P=0.02) and marital status (β=0.56, P=0.02) were significantly related to cognitive decline. Gender (β=-0.17, P<0.01) and hearing loss (β=0.08, P=0.02) correlated with anxiety indicators; gender (β=-0.84, P=0.02) and hearing loss (β=0.04, P=0.01) also correlated with depression indicators. Conclusion:Results indicated a correlation between hearing loss and cognitive decline, and between hearing loss and anxiety and depression among community-dwelling older adults in Beijing.

Malignant tumors are currently seriously endangering human health and life， which has become one of the main causes of death in China. In modern Western medicine， they are mainly tackled by surgery， chemotherapy， and radiotherapy， but the death toll continues to rise year by year. At present， most of the anti-tumor chemotherapeutics used in clinical practice have toxic and side effects， affecting the anti-tumor efficacy and the conditions after treatment. Long-term medication will also induce drug resistance， making the good anti-tumor effect difficult to be achieved. With the vigorous development of traditional Chinese medicine （TCM）， it has played a crucial role in the fight against tumors. It is believed in TCM that "heat toxin" is one of the important causes of tumors. Therefore， the methods of clearing away heat and removing toxin are often emphasized in the treatment of tumors， and the resulting outcomes are satisfactory. There are many Chinese herbs and Chinese herbal compounds classified into the heat-clearing and toxin-removing type. Xihuangwan， a classic heat-clearing prescription， is composed of Calculus Bovis， Moschus， Olibanum， and Myrrh and has the effects of clearing away heat， removing toxin， eliminating edema， and dissipating mass， which is mainly used to treat carbuncle， pustule， scrofula， multiple abscess， and cancer caused by heat-toxin obstruction. In modern clinical practice， it has been employed in patients with lung cancer， breast cancer， gastric cancer， liver cancer， colorectal cancer， and other malignant tumors， especially during the advanced stage， as a routine or adjuvant treatment for alleviating their clinical symptoms and improving their quality of life. The main active components of Xihuangwan are pentacyclic triterpenoids （such as masticinic acids）， volatile oils， steroids （like porcine deoxycholic acid）， and bilirubin， which have been proved effective in anti-tumor. This paper reviewed the prescription source， pharmaceutical research， clinical anti-tumor research， and pharmacological mechanisms of Xihuangwan， which has provided reference for further expanding the anti-tumor applications of Xihuangwan and enhancing its secondary development.

Objective:To explore the efficacy and safety of anti-tumor necrosis factor alpha (TNFα) monoclonal antibodies (mAbs) for severe/refractory vasculo-Behcet′s disease (BD).Method:The clinical data of severe/refractory vasculo-BD patients treated with anti-TNFα mAbs were retrospectively analyzed. Response of anti TNFα mAbs was analyzed. The dosage changes of glucocorticoid, the level of erythrocyte sedimentation rate (ESR) and hypersensitive C-reactive protein (hsCRP) before and after treatment were recorded, as well as side effects.Result:Sixteen patients were enrolled. Arterial lesions were reported in 12 patients, including 9 with arterial aneurysm, 6 with arterial dilation, 2 with stenosis and 2 with occlusion. Seven patients presented venous thrombosis, including lower extremity veins ( n=6), cerebral venous sinus ( n=2) and inferior vena cava system ( n=2). Two cases had both arterial and venous involvement. Before the application of TNFα mAbs, all 16 patients failed to response to prednisone or its equivalent dose of 40 (7.5-90) mg/d in combination with cyclophosphamide, methotrexate, thalidomide or azathioprine for median 4 (0-156) months. After a mean duration of treatment for (17.1±6.5) months, 15 patients achieved complete remission and 1 patient achieved partial remission. Three patients received surgery without any postoperative complications. After using anti TNFα mAbs, the dosage of prednisone [5(0-12.5)mg/d vs. 40(7.5-90)mg/d, P<0.01], ESR [(7.3±4.6) mm/1h vs. (33.5±26.7) mm/1h, P<0.01] and hsCRP [1.9(0.2-11.4) mg/L vs. 24.3(0.4-113.9) mg/L, P<0.01] were significantly decreased. Side effects were observed in 2 patients. One developed pulmonary infection 12 months after adalimumab with conventional treatment. Another patient had allergy to infliximab then switched to adalimumab. Conclusion:In combination with corticosteroids and immunosuppressants, anti-TNF α mAbs are effective and well-tolerated in severe/refractory vasculo-BD, with a favorable steroid -sparing effect and rare postoperative complications.

Objective To investigate the value of transcranial Doppler ultrasonography(TCD)for assessing the cerebrovascular reactivity (CVR)in obstructive sleep apneahypopnea syndrome (OSAHS)patients.Methods Sixty OSAHS outpatients and inpatients admitted to our neurology department from August 2015to December 2016served as an OSAHS group,then further divided into mild group(n=15),moderate group(n=27)and severe group(n=18)according to apneahypopnea index(AHI).Meanwhile,20healthy individuals served as a control group.They underwent TCD on admission to detect their CVR,including the average velocity of cerebral artery blood flow(Vm)during calm breathing and after breath holding.The breath holding index(BHI) was calculed.The relationship between BHI and CVR was analized by pearson linear correlation analysis. Results There was no statistically significant difference in Vm during calm breathing between the OSAHS and control groups(73.64±9.87cm/s vs 72.79±8.68cm/s,P＞0.05).Both of Vm after breath holding and BHI of the OSAHS group were lower than those of the control group(88.63±6.65cm/s vs 93.26±7.12cm/s,0.71±0.16 vs 0.93±0.37,P＜0.01).Both of Vm after breath holding and BHI of the mild group were the highest,while the severe group had the lowest values and the moderate group was in between(P＜0.05).No significant correlation was found between AHI and Vm during calm breathing(r=0.197,P=0.052),while AHI was negatively correlated with Vm after breath holding and BHI(r=-0.557,P =0.011;r=-0.605,P=0.000).Conclusion TCD can detect CVR changes in OSAHS patients,whose Vm after breath holding and BHI decrease significantly.The more severe the OSAHS is,the lower the CVR is.

Three patients diagnosed as amyloidosis secondary to ankylosing spondylitis (AS) in Peking Union Medical College Hospital are reported.All 3 cases had renal abnormalities,2 cases were complicated with cardiac abnormalities,1 case was complicated with gastrointestinal abnormalities and 1 case was complicated with skin moss-like changes.Eleven cases of AS with amyloidosis were retrieved from Wanfang database and Pubmed database from 1997 to 2017.In total 14 cases,the male and female ratio was 5:2,the mean age of AS onset was (29.6± 10.5)years,and the mean age of amyloidosis diagnosed was(44.0± 10.5)years.Eight patients presented with edema and severe proteinuria,2 cases showed diarrhea,2 cases showed dyspnea,while 2 cases had no obvious symptoms.Thirteen cases had renal abnormalities and 1 case had only heart involvement.Of the 13 patients with renal involvement,2 cases were complicated with cardiac abnormalities,2 cases complicated with gastrointestinal abnormalities,2 cases complicated with skin abnormalities.The mean ESR was(83.7±22.6)mm/1 h,C reactive protein was(89±59)mg/L at onset.After the diagnosis of amyloidosis,9 patients were treated with TNF-α inhibitors,3 cases received symptomatic therapy,1 case underwent renal transplantation and 1 case were treated with peritoneal dialysis.In 9 patients treated with TNF-α inhibitors,8 cases were relieved and 1 case lost follow-up.Three patients who received symptomatic treatment all died,while patients receiving kidney transplantation and peritoneal dialysis were in stable condition.The study indicates that secondary amyloidosis often occurs in young male AS patients who have long course and poorly controlled disease,the kidney is the most common affected organ.TNF-α inhibitors may be effective for treatment of amyloidosis secondary to AS.
