Objective To understand the status of hand hygiene(HH) among patients hospitalized in departments of infectious diseases and their families in Yantai City, and provide reference for HH intervention.Methods Patients and their families(n=221) in departments of infectious diseases of secondary and above levels of hospitals as well as infectious diseases hospitals in Yantai in July-August 2015 were selected for questionnaire survey, education and implementation status of HH were investigated;hand bacteriological sampling was performed on some patients and their families (n=62) to investigate effect of hand-washing.Results 61.99% of patients and their families had received verbal HH education, only 18.55% indicated to have seen health care workers(HCWs) to perform the six step hand-washing method;50.68% of the respondents didn't understand the six step hand-washing method, and 85.52% never performed the six step hand-washing, the main reason is that they didn't know how to perform.93.21% of patients(n=206) and their families believed that hand-washing was important.The cognition of HH opportunities in daily life was relatively higher(61.54%-94.51%),and in hospital environment was relatively lower(36.15%-49.23%),only 36.15% of the families washed hands before left the hospital.Unqualified rate of detection results of sampling of hands of patients with infectious diseases and their families was 83.87%.Conclusion Patients with infectious diseases and their families are deficient in HH knowledge and behavior, medical institutions should carry out systematic and standard HH education to reduce the risk of healthcare-associated infection.

Objective To evaluate the cost-effectiveness of early enteral nutrition (EEN) in elder patients undergoing gastrectomy for gastric carcinoma. Methods An outcome-based retrospective review of 52 patients who had undergone gastrectomy for gastric carcinoma between July 1999 and June 2002 was performed .There were 27 patients in the EEN group, and 25 in the TPN group. Results The mean postoperative hospital days of the EEN group was significantly less than that of the TPN group (16.3 d vs. 21.3 d, t =4.6814, P

Functional magnetic resonance imaging(fMRI),as a noninvasive technology of measuring human brain function,has been used in neurolingustic research on normal subjects and on patients with brain damage,to investigate the neural basis underlying language processing.Such studies complement and development the classical knowledge accumulated on aphasia,provide new insights into the neural mechanisms of aphasia and the plasticity of recovery from aphasia,and might be helpful to evaluate the capability of language functional recovery and the efficiency of rehabilitative strategies also.

Objective To investigate the onset of left ventricular remodeling (LVRM) after acute myocardium infarction (AMI) and its changes within 6 hours in dogs on echocardiography. Methods AMI was induced in 14 dogs by ligating the left anterior descending arteries. Eight myocardium infarcted models were successful and were sacrified for pathological study. The indices of LVRM: wall infarction thickness (WIT), the wall motion score index (WMSI), left ventricular end-diastolic volume (LVEDV), left ventricular end-systolic volume (LVESV) and left ventricular ejection fraction (LVEF) were evaluated before and 1 h, 2 h, 3 h, 4 h, 5 h and 6 h after operation. Results Compared with the pre-operation, WIT and LVEF were decreased (P<0.01), LVESV and WMSI were increased (P<0.01), and LVEDV was increased (P<0.05 or P<0.01) at every time point after operation. WIT had no significant difference at 1 h, 2 h, 3 h, 4 h, 5h and 6h after operation (P＞0.05). LVEDV, LVESV were higher (P<0.05) and LVEF was lower (P<0.05 or P<0.01) at 4 h, 5 h, and 6 h than at 1 h, and 2 h after operation. WMSI was higher at 3 h, 4 h, 5 h, and 6 h than at 1h (P<0.05). Conclusions In our experiment, LVRM occurred at 1 h after AMI in dogs. Thus echocardiography may evaluate early LVRM.

OBJECTIVETo improve the outcome of the face-lift with a craniofacial contouring procedure.

METHODSThirty-seven patients aged 29-53 years (31 in female, 6 in male) were treated through a bicoronal incision. The facial tissue was lifted through a subperiosteal procedure and the facial skeleton was remodeled in three dimensions by osteotomies.

RESULTSThe results were satisfactory after the 3-12 months of the follow-ups.

CONCLUSIONSThe Face-lift combined with the facial aesthetic sculpturing may be more effective for the aging-face rejuvenating.

OBJECTIVETo compare the ability of osthole (OST) and genistein (GEN) in enhancing bone peak bone mass of rats to prevent osteoporosis.

METHODSThirty-six female one-month-old SD rats of (125 +/- 3) g body weight were randomly divided into three groups, 12 rats in each group, one group was orally administered osthole at 9 mg x kg(-1) d(-1), one group was given genistein at 10 mg x kg(-1) d(-1) and another was given equal quantity of distilled water as the control. The body weight was monitored weekly and the bone mineral density (BMD) of total body was measured every month. All rats were sacrificed after three months, the femoral bone mineral density, the serum levels of osteocalcin (OC) and anti-tartaric acid phosphatase 5b (TRACP 5b) were measured by Elisa. The bone microarchitectures were analyzed with micro-CT and the bone biomechanics properties were tested with universal material machine.

RESULTSNo significant differences were observed between O-treated or GEN group and the control for the food-intake and body weight during three months. However, the rats treated with OST had significant higher BMD for both total body and femur than the control and GEN group. The O-treated rats also had higher level of serum OC and lower level of TRACP 5b. Besides, they owned bigger bone volume/tissue volume, trabecular thickness, trabecular number but smaller trabecular spacing. In the three point bending tests of femurs,they were found to have larger maximum load, the young's modulus and structural model index (SMI).

CONCLUSIONOrally administered osthole could efficiently increase the peak bone mass of rats,which provide new ideas for preventing osteoporosis.

RNA-Sequencing (RNA-Seq) is a newly-developed method in transcriptome research, it can afford more accurate transcription information and be more quickly by using Next-generation Sequencing (NGS) technology. RNA-Seq has been widely used in various biological fields. Genuine traditional Chinese medicines (TCM), with good quality and therapeutic effect, were always praised highly and used by famous physicians. The geo-herbalism formation of TCM is based on the product of the gene expression at specific space and time. So it has been a research hotspot to analyze the mechanism of biosynthesis through RNA-Seq in the study on the secondary metabolism of medicinal plant. This article mainly illustrates the RNA-Seq and its advantages, it also discusses the potential application in genuine TCM, and it can provide useful information for other researchers.

Objective To determine the effect of paired immunoglobulin-like receptor B (PirB) on growth of retinal ganglion cells (RGCs) in vitro.Methods Expression of PirB in RGCs isolated from wild-type C57 BJ/6 mice was measured by immunofluorescence.Real-time PCR and Western blot were performed to detect PirB expressions in RGCs cultured for 1,3,5,7 and 9 days.Primary cultured RGCs were left untreated as controls,transfected with lentiviral-delivered PirB RNAi as Group A,lentiviral-delivered NgR RNAi as Group B,lentiviral-delivered PirB RNAi plus ciliary neurotrophic factor (CNTF) as Group C,lentiviral-delivered NgR plus CNTF as Group D,and only CNTF as Group E.Growth and development of RGCs were evaluated by MTT assay and morphological analysis.Results Immunofluorescence confirmed expression of PirB in RGCs,with its mRNA and protein levels changing from increase at first to decrease later with time,up to peak at days 5 and 7.PirB and NgR were respectively down-regulated in Groups A and B.Viability of RGCs was improved in Group A compared with control group [(40.2 ± 5.3) μm vs (29.1 ± 3.8) μm at day 3 ; (72.2 ± 4.2) μm vs (52.3 ± 8.2) μm at day 5,both P ＜ 0.05].By contrast,no significant difference was found in viability of RGCs among Groups B,D and E when compared to control group (P ＞ 0.05).Growth of RGCs between Groups A and C revealed insignificant difference (P ＞ 0.05).Conclusion Knockdown of PirB is beneficial for the growth of RGCs,suggesting a novel method to treat optic nerve injury.
