Alzheimer's disease (AD) and other aging-related diseases have become an important public health issue in China. However, current clinical drugs have failed to reverse the pathological process of AD. The holistic approach of traditional Chinese medicine offers advantages in improving cognitive function in AD through multiple molecular pathways, and may have potential for preventing AD. This paper summarizes the effects of classical traditional Chinese medicine and its active components in the improvement of AD-related cognitive dysfunction and describes the functional targets and related molecular mechanisms. This may have significance for the prevention and treatment of AD through multi-target intervention.

Objective To explore the incidence of post-transplant diabetes mellitus (PTDM) by means of fasting plasma glucose (FPG) and other associated risk factors in patients surviving for more than 1 year after renal transplantation.Methods A total of 428 non-diabetic patients,who underwent kidney transplantation from 1 January,1993 to 31 December,2008,were followed up in order to ascertain the prevalence of PTDM after transplantation and other associated risk factors by means of FPG.Results Of the 428 patients,87 developed PTDM (20.3％) within a mean follow-up of (5.65 ± 3.68) years after renal transplantation.The onset of PTDM occurred in 57 patients (65.5％ of total PTDM) primarily within the first year after transplantation.Univariate analysis showed that older age,body mass index (BMI),smoking history,family history of diabetes mellitus,deceased donor transplantation,hepatitis C virus infection,cytomegalovirus infection,FPG before transplantation as well as 1 week after transplantation,total cholesterol and triglyceride before transplantation,switching from cyclosporine to tacrolimus(FK506),and peak plasma concentration of cyclosporine in the first 6 and 12 months were associated with the onset of PTDM.The prevalence of PTDM was markedly elevated in the group who has cyclosporine converted to FK506 (P＜0.05),but not in the group with cyclosporine converted to rapamycin.By multivariate analysis,FPG before transplantation,age,BMI,and deceased donor transplantation were independently associated with the onset of PTDM.Conclusions There is high incidence of PTDM in patients following renal transplantation; and early diagnosis,treatment as well as prevention are mandatory.

Objective To explore the relationship between X - linked spondyloepiphyseal dysplasia tarda (SEDL) gene escaping X chromosome inactivation( XCI) and SEDL phenotype. Methods RT - PCR was performed on total RNA which was isolated from blood samples of patients, female carriers and controls. Patients and female carriers were selected from the pedigree with SEDL caused by the mutation (IVS2 - 2A→C) of the gene. cDNA was analyzed by polyacrylamide gelelectrophoresis(PAGE). Results PAGE data indicateed that female carriers expressed both normal and mutant SEDL mRNA,meaning the SEDL gene escaping XCI. Family investigation showed carrier females in the SEDL pedigree presented no symptoms. Conclusions The SEDL gene escaping X chromosome in-activation is firstly identified from human body. This may explain that carrier females present no symptoms.

Objective To explore the efficacy and safety of the resection of prostate-tangerine techniquewith 980 nm diode laser benign prostatic chyperplasia(BPH).Methods Data of 60 patients with highvloum BPH treated with the resection of prostate-tangerine technique with 980 nm diode laser were reviewed.The age of the patients were 65-89 years old,and mean prostate volume was 74.5± 13 ml.The mean operative time,blood loss were oberseved and recored,the international prostate symptom score(IPSS),quality of life score (QOL),maximum urinary flow rate(Qmax) and residual urine volume (PVR) were collected and analyzed.Results The 60 cases were safe during the perioperative period.The average operation time was (70.2± 16.9) min,and there was no obvious bleeding during the operation and no blood transfusion cases.The time of remove the transurethral catheter was 2-5 d,and the mean time was (2.4±0.3) d.Follow up 1-3 months after operation,a significant reduction in IPPS was reported (P =0.000),significant durable improvements in Qmax,PVR before operation(P=0.000).Conclusion Transurethral vaporization of 980 nm diode laser could be a safe and effective treatment modality for BPH.

Objective To analyze the bone metabolism in hospitalized patients with Graves disease and the changes after 131I therapy.Methods The differences of bone metabolism were analyzed between 315 patients with Graves disease and 300 normal controls in a case-control study.The changes in bone turnover markers and BMD levels before and one year after 131I therapy were observed in 60 patients.Results Compared to normal control,bone turnover markers were markly higher and BMD levels were lower in patients with Graves disease.The level of thyroid hormones were positively related to bone turnover markers,while negatively related to total hip BMD (Z-score).But there was no linear relationship with lumbarand femoral neck BMD (Z-score).After one year of 131I therapy,bone turnover markers were markly lower than that before treatment,while BMD levels were partly higher than that before treatment.Conclusions In Graves disease patients,bone turnover markers were generally increased,while BMD levels decreased compared with normal people.After 131I therapy,along with the improvement of thyrotoxicosis,the high bone turnover rate can be suppressed,and BMD can partly recover.

Objective To investigate the influence of“double low”technology(low concentration iodinated contrast agent and low-dose scan) combined with body mass index(BMI) on radiation dose and image quality of contrast-enhanced upper abdominal CT examination. Methods One hundred and twenty patients who received upper abdominal enhanced CT examination were randomly divided into 4 groups:group A1, the iodinated contrast agent iodixanol(270 mg/ml), BMI<18.5 kg/m2 and 80 kVp;group A2, the iodinated contrast agent iodixanol(270 mg/ml), 18.5 kg/m2≤BMI≤24.9 kg/m2 and 100 kVp; group B1, the iodinated contrast agent ioversol(320 mg/ml),<18.5 kg/m2 and 120 kVp; group B2, the iodinated contrast agent ioversol(320 mg/ml), 18.5 kg/m2≤BMI≤24.9 kg/m2 and 120 kVp. Image quality was subjectively scored, the objective parameters(noise, CT values of abdominal aorta and liver parenchyma, contrast noise ratio of abdominal aorta and liver parenchyma) were evaluated and radiation dose was recorded. The differences of the indexes between A1 and B1 groups, A2 and B2 groups were compared with Mann-Whitney U test and pared-samples t test. Results All CT images were good. No images with 4 scores were obtained. No significant difference was found between group A1 and B1, between group A2 and B2(P>0.05). There was no significant difference in contrast noise ratio of liver parenchyma(P>0.05), while significant differences existed in CT values of abdominal aorta and liver parenchyma, contrast noise ratio of abdominal aorta between group A1 and B1(P<0.05). Significant differences existed in the parameters above mentioned between group A2 and B2, respectively(P<0.05). Radiation dose was lower in group A1 than in group B1 and in group A2 than in group B2(P<0.05), respectively. Radiation dose was decreased by 40.1%(0.89/2.22) in group A1 than group B1 while radiation dose decreased by 56.9%(3.02/5.31) in group A2 than group B2. Conclusion According to BMI, the low concentration iodinated contrast agent and low-dose scan CT scanning technology could effectively reduce radiation dose and generate ideal images during the contrast-enhanced upper abdominal CT examination.

Purpose Estimation of the degree of pulmonary artery stenosis (PS) in children patients before treatment can provide an important basis for the choice of treatment.This study explores the accuracy of non-invasive continuous wave Doppler (CW) and electrocardiogram (ECG) in estimating the degree of PS in children patients.Materials and Methods Sixty consecutive cases of PS children were collected from January 2012 to August 2016 in the General Hospital of Shenyang Military.The right ventricular pressure was estimated by measuring cross-pulmonary artery pressure gradient by CW,or estimated by measuring the amplitude of the V1R wave by ECG,which was then compared with that measured by cardiac catheterization respectively.Results The right ventricular pressure estimated by measuring cross-pulmonary artery pressure gradient by CW was positively correlated with that measured by cardiac catheterization (r=0.88,P＜0.05).The right ventricular pressure estimated by measuring the amplitude of the V1R wave by ECG was also positively correlated with that measured by cardiac catheterization (r=0.83,P＜0.05).Conclusion The right ventricular pressure estimated by CW or ECG has good consistency with that measured by cardiac catheterization.Both CW and ECG can be used as noninvasive methods for estimating the degree of PS in children.
