Objective: To examine the association of body mass index (BMI) and waist circumference (WC) with frailty among oldest-old adults in China. Methods: A total of 7 987 people aged 80 years and older (oldest-old) who participated in the Chinese Longitudinal Healthy Longevity Survey (CLHLS) in 2017-2018 were included. Information on demographic characteristics, behavior pattern, diet, activities of daily living, cognitive function, health status, disease condition were collected by questionnaire and physical examination. Generalized linear mixed model and restricted cubic splines (RCS) were used to analyze the association of BMI and WC with frailty. Results: The mean age of all participants was 91.7 years, and their mean BMI and WC were (21.3±3.5) kg/m² and (82.9±10.5) cm, respectively. The proportion of male was 42.3% (3 377/7 987), and the proportion of people with frailty was 33.7% (2 664/7 987). After controlling confounding factors, compared with T₂ (19.1-22.1 kg/m²) of BMI, the OR (95%CI) of the female T₁ (<19.1 kg/m²) and T₃ (≥22.2 kg/m²) group was 1.39 (1.17-1.65) and 1.27 (1.07-1.52), respectively. Compared with T₂ (77-85 cm) of WC, the OR (95%CI) of female T₁ (<77 cm) and T₃ (≥86 cm) group was 1.20 (1.01-1.42) and 1.10 (0.93-1.31), respectively. The results of multiple linear regression model with restrictive cubic spline showed that there was a non-linear association of BMI and WC with frailty in female. Conclusion: There is a U-shaped association of BMI and WC with frailty in female participants.

Yi-Qi-Fu-Mai (YQFM) is extensively used clinically to treat cardiovascular diseases in China. To explore the anti-hypoxia effect of the extract of YQFM preparation (EYQFM), the EYQFM (1.4, 2.8, and 5.5 g·kg(-1)·d(-1)) was assessed for its heart-protective effect in a chronic intermittent hypoxia (CIH) animal model (oxygen pressure 7%-8%, 20 min per day) for 28 days of treatment. Betaloc (0.151 6 g·kg(-1)·d(-1)) was used as a positive control. The histopathological analyses of heart in CIH mice were conducted. Several cardiac state parameters, such as left ventricular ejection fractions (EF), stroke volume (SV), expression of creatine kinase (CK), lactate dehydrogenase (LDH), superoxide dismutase (SOD), and malondialdehyde (MDA) were measured. The results showed that treatment with EYQFM markedly reversed swelling of the endothelial cells and vacuolization in the heart when compared with the model group. Further study demonstrated that EYQFM significantly improved ventricular myocardial contractility by increasing EF and SV. In addition, EYQFM inhibited the activity of CK, LDH, decreased the level of MDA and improved SOD activity. The results demonstrated that EYQFM significantly improved the tolerability of myocardium to hypoxia and ameliorated the cardiac damage in the CIH model.

BACKGROUNDData on the epidemiology of hypertension in Chinese non-dialysis chronic kidney disease (CKD) patients are limited. The aim of the present study was to investigate the prevalence, awareness, treatment, and control of hypertension in the non-dialysis CKD patients through a nationwide, multicenter study in China.

METHODSThe survey was performed in 61 tertiary hospitals in 31 provinces, municipalities, and autonomous regions in China (except Hong Kong, Macao, and Taiwan). Trained physicians collected demographic and clinical data and measured blood pressure (BP) using a standardized protocol. Hypertension was defined as systolic BP ≥ 140 mmHg and/or diastolic BP ≥ 90 mmHg, and/or use of antihypertensive medications. BP < 140/90 mmHg and < 130/80 mmHg were used as the 2 thresholds of hypertension control. In multivariate logistic regression with adjustment for sex and age, we analyzed the association between CKD stages and uncontrolled hypertension in non-dialysis CKD patients.

RESULTSThe analysis included 8927 non-dialysis CKD patients. The prevalence, awareness, and treatment of hypertension in non-dialysis CKD patients were 67.3%, 85.8%, and 81.0%, respectively. Of hypertensive CKD patients, 33.1% and 14.1% had controlled BP to < 140/90 mmHg and < 130/80 mmHg, respectively. With successive CKD stages, the prevalence of hypertension in non-dialysis CKD patients increased, but the control of hypertension decreased (P < 0.001). When the threshold of BP < 130/80 mmHg was considered, the risk of uncontrolled hypertension in CKD 2, 3a, 3b, 4, and 5 stages increased 1.3, 1.4, 1.4, 2.5, and 4.0 times compared with CKD 1 stage, respectively (P < 0.05). Using the threshold of < 140/90 mmHg, the risk of uncontrolled hypertension increased in advanced stages (P < 0.05).

CONCLUSIONSThe prevalence of hypertension Chinese non-dialysis CKD patients was high, and the hypertension control was suboptimal. With successive CKD stages, the risk of uncontrolled hypertension increased.

Currently, image-based 3-dimentional (3D) planning brachytherapy allows for a better assessment of gross tumor volume (GTV) and the definition and delineation of target volume in cervix cancer. In this study, we investigated the feasibility of our novel computed tomography (CT)-guided free-hand high-dose-rate interstitial brachytherapy (HDRISBT) technique for cervical cancer by evaluating the dosimetry and preliminary clinical outcome of this approach. Dose-volume histogram (DVH) parameters were analyzed according to the Gynecological GEC-ESTRO Working Group recommendations for image-based 3D treatment in cervical cancer. Twenty cervical cancer patients who underwent CT-guided free-hand HDRISBT between March 2009 and June 2010 were studied. With a median of 5 (range, 4-7) implanted needles for each patient, the median dose of brachytherapy alone delivered to 90% of the target volume (D90) was 45 (range, 33-54) Gyα/β10 for high-risk clinical target volume (HR-CTV) and 30 (range, 20-36) Gyα/β10 for intermediate-risk clinical target volume (IR-CTV). The percentage of the CTV covered by the prescribed dose (V100) of HR-CTV with brachytherapy alone was 81.9%-99.2% (median, 96.7%). With an additional dose of external beam radiotherapy (EBRT), the median D90 was 94 (range, 83-104) Gyα/β10 for HR-CTV and 77 (range, 70-87) Gyα/β10 for IR-CTV; the median dose delivered to 100% of the target volume (D100) was 75 (range, 66-84) Gyα/β10 for HR-CTV and 65 (range, 57-73) Gyα/β10 for IR-CTV. The minimum dose to the most irradiated 2 cc volume (D2cc) was 73-96 (median, 83) Gyα/β3 for the bladder, 64-98 (median, 73) Gyα/β3 for the rectum, and 52-69 (median, 61) Gyα/β3 for the sigmoid colon. After a median follow-up of 15 months (range, 3-24 months), two patients experienced local failure, and 1 showed internal iliac nodal metastasis. Despite the relatively small number of needles used, CT-guided HDRISBT for cervical cancer showed favorable DVH parameters and clinical outcome.

Objective To evaluate the implementation effect of the clinical nursing pathway on patients with cerebral hemorrhage by using the Meta-analysis.Methods The databases of WanFang Data、CMA、CHDL and CBM were searched.The controlled studies comparing clinical nursing pathway and traditional nursing were included.Data collection and literature evaluation were performed by two reviewers independently.RevMan 5.0 was used for the Meta-analysis.Results Totals of 12 literatures were included in Meta-analysis.The results showed the statistical difference between clinical nursing pathway and traditional nursing for cerebral hemorrhage's patients in average length of stay,average hospitalization expenses,patients' satisfaction,patients' health education awareness and the incidence of complication (P ＜ 0.01 ).However,most trials included in the review were of low quality.Conclusions The clinical nursing pathway is beneficial in implementation effect comparing with traditional nursing.But there are a higher risk of bias in the literatures,the results need a large number of clinical nursing practice and higher quality literatures to support.

Objective To investigate late stent malapposition or vessel remodeling post chitosan/heparin layer-by-layer self assembly coating stent (LBL) implantation in porcine.Methods A total of 32 stents [ bare metal stent ( BMS,n =9),sirolimus-eluting stent ( SES,n =11 ) and LBL ( n =12 ) ] were implanted into coronary arteries of 16 porcine.Intravascular ultrasound (IVUS) was performed immediately after stenting and at 1 month after stenting to measure vessel area (VA),stent area (SA) and lumen area (LA).Neointima area (NA) was measured at 1 month post stenting by IVUS to detect signs of stent malapposition and to determine remodeling index (RI). Histopathology was performed at 1 month post stenting to observe vessel wall structure and stent malapposition status.Results No sign of stent malapposition was detected,VA and SA/LA were similar among groups immediately after stent implantation.At 1 month follow-up,none of three groups showed stent malapposition.VA,SA,NA and LA were ( 7.30 ±0.77),(6.83 ±0.76),(1.40 ±0.96) and (5.43 ±0.88)mm2 in LBL group,(7.13 ±0.69),(6.63 ±0.71 ),(0.28 ±0.35) and (6.34 ±0.89)mm2 in SES group,(7.48 ±0.70),(7.00 ±0.52),(2.69 ±1.58) and (4.31 ± 1.28)mm2 in BMS group.VA and SA were similar among groups ( all P ＞0.05 ).LA in LBL group was smaller than SES group ( P ＜ 0.01 ) and significantly larger than in BMS group ( P ＜0.05 ).NA in LBL group was larger than SES group (P ＜0.01 ) and significantly smaller than in BMS group (P ＜ 0.05 ).RI in LBL,SES and BMS groups was 0.95 ± 0.07,1.02 ± 0.04 and 0.98 ± 0.04 ( P ＞0.05).Conclusions There is no late stent malapposition or abnormal remodeling post LBL,SES and BMS implantation up to 1 month in this porcine model.LA in LBL group is smaller than SES group and larger than BMS group at 1 month after implantation in this porcine model.

OBJECTIVETo investigate the killer cell immunoglobulin-like receptor (KIR) gene frequencies and genotypes distributions in the Inner Mongolian population.

METHODSNinety genomic DNA samples were extracted from blood samples of randomly chosen Mongolian individuals. Gene-specific PCR amplification was used to identify genes present or absent for 16 KIR loci. KIR genotype distributions were obtained and compared to that of 24 populations published in literatures using principal component analysis by SAS8.0 software. Genetic tree was constructed by the calculate Nei's genetic distance.

RESULTS(1) The frequency of KIR 2DL2, 2DS2 in Mongolian individual is higher than that in north Mongoloid and less than that in Caucasian. (2) Haplotype AA was identified in 37.78% of individuals, which is higher than that in north Mongoloid and lower than that in Caucasian. (3) Mongolian was considered between north Mongoloid and Caucasian by principal component and genetic tree analysis.

CONCLUSIONMongolian might be affected by the north Mongoloid and Caucasian, and showed intermediate between the two populations.
