Objective To investigate the relationship between elderly male patients with coronary heart diseases (CHD) and endogenous androgen level and other related factors.Methods 28 male patients with acute coronary syndrome (ACS) were chosen as research group,28 male patients with stable angina pectoris (SAP) were chosen as observation group,and 28 healthy male people were selected as control group.All of three groups were checked by carotid artery Doppler ultrasonography and the peripheral blood concentration of testosterone (T),TC,LDL-C,Glu,CRP were measured,BMI was calculated in all three groups.Results Peripheral blood concentration of T,TC,LDL-C,Glu in ACS group and SAP group were significantly higher than those of the control group(P ＜0.05).IMT and number,quality of plaque in patients with ACS and SAP were significantly different compared with the control group (P ＜ 0.05).T,Tc,LDL-C,CRP,BMI,IMT,unstable plaque were significantly different between ACS group and SAP group(P ＜ 0.05).Glu had no statistical difference between ACS group and SAP group (P ＞ 0.05).Conclusion Peripheral blood concentration of T was negatively correlated with arterosclerosis,unstable plaque,Tc,LDL-C,BMI in old male CHD patients

Objective To respectively analyze the results and complications of hip arthroplasty for failed intertrochanteric hip fractures treating with internal fixation.Methods From July 2004 to June 2006,32 patients(24 males and 8 females)were treated with hip arthroplasty after the failed internal fixation of intertrochanteric fractures.The mean age was 71 years(range,57-81 years)at the time of the hip arthroplasty.The average interval from fracture to arthroplasty was 40 months(range,5-70 months).Fifteen patients had been treated with sliding hip screw,10 with intramedullary nail,5 with plate and screws,2 with multiple screws.The failure modes were nonunion in 8 patients,implant cut out from the femoral head in 9,avascular necrosis of the femoral head in 7,and traumatic arthritis in 8 patients.Cemented stems were used in 12 hips,and uncemented stems in 20 hips.Standard prostheses were used in 25,long-stem prostheses in 7.Results Twenty-eight patients were followed up for a minimum of 4 years after the hip arthroplasty,with the mean period of 5 years(range,4-6 yeas).For these 28 patients,the average preoperative Harris Hip Score was 37(range,32-45),and 88(range,84-95)at the latest follow-up.The average acetabular inclination was 44°(range,42°-48°).No loosing was found in cotyloid components.Nine of 10 cemented femoral components had cementation rated as grade C,and 1 as grade A.Three had heterotopic bone six months postoperatively,and 2 were Brooker type Ⅱ,one was type Ⅲ.Conclusion Hip arthroplasty is an effective salvage procedure after the failed treatment of an intertrochanteric fracture in an older patient.

OBJECTIVETo study the difference in the pharmacokinetics of emodin in Zhiganning capsules and Rhizoma Polygontum Cuspidatum by nonaqueous RP-HPLC.

METHODThe rats were orally administered with the extraction of Rhizoma Polygontum Cuspidatum and Zhiganning capsules. After hydrolysis and extraction, the content of emodin in the plasma is determined by Nonaqueous RP-HPLC.

RESULTThe concentration-time profiles of emodin fit two-compartment model. The pharmacokinetics parameters including, t1/2alpha, AUC(0-infinity), CL(s) and C(max) of emodin in the group of Rhizoma Polygontum Cuspidatum were significantly different from these in the group of its compounds.

CONCLUSIONThere is a significant difference in pharmacokinetics of emodin between zhiganning capsules and the extraction of Rhizoma Polygontum Cuspidatum.

Objective To understand oral health of the elderly in nursing home in Songjiang District, Shanghai, and to provide references for improving their oral health. Methods A total of 375 elderly people in 15 nursing homes in Songjiang District were investigated by questionnaires and oral examination.Tooth loss, denture repair, periodontal condition and oral hygiene habit were analyzed. Results The rate of the tooth loss reached 94.13%.The tooth loss rate in females (96.09%) was significantly higher than that in males (91.03%) (P < 0.01).The rate of complete edentulous jaws was 28.27%.There was a significant difference between the rate of complete edentulous jaws in females (34.35%) and in males (18.62%)(P < 0.05).The rate of denture restoration was 91.51% (97/106).The number of existing teeth per capita was 11.54, and the number of teeth per capita in males (14.48 per person) was significantly higher than that in females (9.70 per person) (P < 0.05).Both the rate of the tooth loss of upper and lower posterior teeth were significantly higher than that of upper and lower anterior teeth (P < 0.01).Thirty-three percent (33.33%) of the elderly brushed their teeth more than twice a day, and almost 20.53% of them didn′t brush their teeth. Conclusion The oral health of the elderly in the nursing homes in Songjiang District is not satisfactory at present.It is necessary to strengthen the publicity and education of oral health care for the elderly in nursing homes in cooperation with multiple departments to improve their awareness of oral health care including appropriate tooth repair for the quality of life.

Background/Aims: Direct‐acting antivirals (DAAs) have been approved for hepatitis C virus (HCV) treatment in patients with end-stage renal disease (ESRD) on hemodialysis. Nevertheless, the complicated comedications and their potential drug-drug interactions (DDIs) with DAAs might limit clinical practice in this special population. Methods: The number, class, and characteristics of comedications and their potential DDIs with five DAA regimens were analyzed among HCV-viremic patients from 23 hemodialysis centers in Taiwan. Results: Of 2,015 hemodialysis patients screened in 2019, 169 patients seropositive for HCV RNA were enrolled (mean age, 65.6 years; median duration of hemodialysis, 5.8 years). All patients received at least one comedication (median number, 6; mean class number, 3.4). The most common comedication classes were ESRD-associated medications (94.1%), cardiovascular drugs (69.8%) and antidiabetic drugs (43.2%). ESRD-associated medications were excluded from DDI analysis. Sofosbuvir/velpatasvir/voxilaprevir had the highest frequency of potential contraindicated DDIs (red, 5.6%), followed by glecaprevir/pibrentasvir (4.0%), sofosbuvir/ledipasvir (1.3%), sofosbuvir/velpatasvir (1.3%), and elbasvir/grazoprevir (0.3%). For potentially significant DDIs (orange, requiring close monitoring or dose adjustments), sofosbuvir/velpatasvir/voxilaprevir had the highest frequency (19.9%), followed by sofosbuvir/ledipasvir (18.2%), glecaprevir/pibrentasvir (12.6%), sofosbuvir/velpatasvir (12.6%), and elbasvir/grazoprevir (7.3%). Overall, lipid-lowering agents were the most common comedication class with red-category DDIs to all DAA regimens (n=62), followed by cardiovascular agents (n=15), and central nervous system agents (n=10). Conclusions HCV-viremic patients on hemodialysis had a very high prevalence of comedications with a broad spectrum, which had varied DDIs with currently available DAA regimens. Elbasvir/grazoprevir had the fewest potential DDIs, and sofosbuvir/velpatasvir/voxilaprevir had the most potential DDIs.

Zerumbone(ZER), one of humulane-type sesquiterpenoids, showed its unique advantage against tumor activities. The main underlying mechanisms include inhibiting the growth and proliferation of cancer cells, inducing apoptosis of cancer cells and differentiation of cancer cells, regulating immune function, inhibiting invasion and metastasis of cancer cells, and reversing multidrug resistance of cancer cells. Studies on ZER focusing its cytotoxic or anti-tumor is one of hot topic. Currently, with the increasing studies on ZER, the clarified mechanisms are getting rich. The present paper describes a summary of its anti-tumor mechanism of action and helps to provide significant reference to more in-depth research.
