Objective: To investigate the current situation and influencing factors of knowledge, attitude and practice (KAP) of fall prevention among the elderly in Huzhou City, Zhejiang Province, so as to provide the evidence for the development of fall intervention for the elderly. Methods: The permanent residents aged 60 years and over in Huzhou City were selected using multi-stratified cluster sampling method from March to April 2023. Demographic information, activity of daily living (ADL), fall risk, and KAP of fall prevention was collected using questionnaire surveys. Factors affecting KAP of fall prevention were identified using a multivariable logistic regression model. Results: Totally 2 160 questionnaires were allocated, and 2 104 valid questionnaires were recovered, with an effective recovery rate of 97.41%. There were 1 063 males (50.52%) and 1 041 females (49.48%), and 861 residents aged 60 to <70 years (40.92%). The awareness of fall prevention knowledge was 84.13%, the percentage of attitude towards fall prevention was 85.88%, and the percentage of practice of fall prevention was 14.59%. Multivariable logistic regression analysis showed that age, educational level, exercise duration and fall risk were associated with the awareness of fall prevention knowledge; age, educational level, marital status, exercise duration, ADL and fall risk were associated with the attitude towards fall prevention; gender, age, educational level, marital status, exercise duration, chronic diseases, ADL and fall risk were associated with the practice of fall prevention (all P<0.05). The desired access to fall prevention knowledge was mainly dominated by medical personnel, accounting for 75.51% (589/780). Conclusions The practice towards fall prevention among the elderly is relatively low in Huzhou City. The KAP of fall prevention is related to age, educational level, exercise duration and fall risk.

Objective To explore the clinical outcome of using modified great toe wrap-around flap to reconstruct degloved thumb and fingers.Methods Eighteen patients were involved.Based on different types of injury,four procedures were carried on for reconstructing degloved thumb and fingers:①Unilateral modified great toe wrap-around flap to reconstruct 9 degloved thumbs of distal proximal level and 3 degloved fingers of proximal interphalangeal joint level.②Unilateral modified great toe wrap-around flap with second toe medial flap to reconstruct 2 total degloved fingers.③Bilateral modified great toe wrap-around flap to reconstruct 2 thumbs.④Bilateral modified great toe wrap-around flap and second toe medial flap with neurolized super thin anterolateral thigh flap to reconstruct 12 degloved fingers.This wrap-around flap carried with entire nail.A triangle flap was reserved at medial plantar of great toe.Results All free flaps were survived in one stage.Fifteen patients were followed up for 8 to 25 months.The contour of reconstructed digit was as same as contralateral digit with satisfactory motion arc and sensation.There was no extensive scar in donor toe.The width of medial plantar triangle flap increased significantly.All patients could walking,running,jumping without restricted.Conclusions With reconstructed by modified great toe wrap-around flap,degloved thumb or finger can be promised with excellent contour and function outcome.In the meantime,the loss of donor foot can be expected to minimal.This procedure is one of the best ways for reconstructing degloved thumb and finger.

Objective To test the feasibility of rescuing 2 impaired nerves by C7 nerve transfer (C7 nerve double-neurotization). Methods Using adult male Sprague-Dawley rats(200 - 250 g),a C7 nerve double-neurotization model was established. At postoperative 2, 4, 6, 8, 12th weeks the recovery underwent muscle-nerve morpholosical, histological examinations and was compared with C7 single neurotization, Results Most of the parameters in double neurotization group approximated to those in the single neurotization groups and normal control group at the end of observation period, thus indicating C7 nerve contains enough nerve fibers to provide sufficient regeneration for 2 recipient nerves. Conclusion Compared to single neurotization, C7 nerve double-neurotization has the advantage of restoring 2 nerve function at same time. This implicates its future clinical application in the treatment of severe brachial plexus avulsion injuries.

Background and purpose: Diffusion-weighted whole-body imaging with background body signal suppression (DWIBS) can be used for magnetic resonance imaging systemic examination, especially in examing the metastatic lesions, lymph node and bone diseases, and the imaging result is similar with PET. This study aimed to evaluate the application value of magnetic resonance DWIBS and positron emission tomography with computed tomography (PET/CT) on malignant metastatic diseases. Methods: Thirty-six patients confirmed with malignant tumors accompanying metastasis by the pathology of operation or biopsy underwent both DWIBS imaging and PET/CT, chi-square test and Kappa test were used for comparing the detection results of metastasis by these 2 imaging methods. Results:Among the 36 malignant tumor patients with 238 metastatic lesions, 218 (91.6%, 218/238) lesions in DWIBS and 209 (87.8%, 209/238) lesions in PET/CT were detected, with 200 lesions detected by the two methods simultaneously, and the concordance rate was 88.7%(211/238);but there was no statistical signiifcance between this two methods (χ2=1.843, P=0.157). Kappa test showed a fair concordance rate between DWIBS and PET/CT (P=0.000).There were different significance between DWIBS and PET/CT in detecting metastatic lesions of brain and bone (P=0.005 and 0.031);But there was no signiifcant differences (P=0.309 and 1.000) in detecting metastatic lesions of lymph nodes and liver. Conclusion:DWIBS could detect metastatic lesions effectively, and there is ifne consistency with PET/CT. DWIBS is more sensitive than PET/CT in detecting metastatic lesions of brain and bone, so DWIBS could be chosed for screening metastatic lesions according to the characteristics of different primary tumors.

Objective To evaluate the efficacy and safety of sirolimus and tacrolimus after renal transplantation.Method PubMed,Web of knowledge,Medline and the Cochrane Library were searched with the terms and Boolean operators as (kidney transplantation OR renal transplantation) AND (sirolimus OR rapamycin) AND (tacrclimus OR FKS06).Results retrieved were last updated on June 9,2014.Language limit of English and Chinese only was applied.Trials were excluded if enrolling recipients of organs other than kidneys,reporting none of the outcomes in point or combining sirolimus with tacrolimus.Patient and graft survival,acute rejection and adverse events were evaluated as primary outcomes and glomerular filtration rate (GFR) was an additional surrogate for renal function.Professional meta-analysis software RevMan 5.1 was employed to analyze the pooled risk ratio (RR) and mean difference (M D) followed by subgroup analysis and sensitivity analysis.Result Fifteen studies were included with 2480 patients.Patients in the sirolimus group showed an increased rate of acute rejection within one-year's follow-up 2.02 (95％ CI 1.37-2.99,P＜0.05) and also a higher risk of adverse events 1.31 (95％ CI 1.02-1.68,P＜0.05).The incidence of hyperlipidaemia was significantly higher with RR =1.75 (95％ CI 1.17-2.61,P＜ 0.01) in the sirolimus group.The other outcomes were insignificantly different between two groups.In subgroups with ATG as immunity induction and higher sirolimus concentration (＞4-8 μg/L),the difference was insignificant (P ＞ 0.05).Conclusion This meta-analysis concluded that sirolimus showed no advantage over tacrolimus when used early after transplantation.When used with higher concentrations,or with ATG as immunity induction,the disadvantages may be avoided.More clinical evidence is needed.

As an important component of modern medicine , the critical care medicine has sprung up for years. Nevertheless, based on the postgraduate education and the further education like 5C training, the existing talent training pattern has been unable to solve the serious problem of the deficiency in the human capital of critical care medicine in hospitals of different levels. With the eco-nomic development of the society and the constant emergence of the new medical technologies , the critical care medical specialty should be quickly established in medical colleges, especially facing the modern demand on curriculum reformation in the undergraduate course. As the “National Compre-hensive Reforms Pilot Unit of Anesthesiology”, the School of Anesthesiology of Wannan Medical Col-lege is obliged to cater for the social need and respond to the national policy. Despite of the insuffi-ciency of teaching and cases, the school endeavors to build up the reformed “2+1+2” curriculum system on the basis of strengthening the major advantages. With the core of the teaching mold reform, the new system aims to enhance the clinical training and introduce the teaching mold reforms of “or-ganic system-based”, PBL and CBL, etc. Therefore, the sound training mold of critical care medicine could be further explored significantly.

Objective: To explore the changes of peripheral leukocyte’s telomere length (LTL) in patients of premature coronary artery disease (PCAD) with inlfuencing factors. Methods: Our research was conducted in 2 sets of groups, by coronary artery condition: PCAD group,n=128 including 88 patients with ACS, 40 with SCAD and Non-CAD group,n=128 subjects; by age status: the age≤30 years, 31-40 years, 41-50 years, 51-60 years had 2, 14, 65, 47 patients in each group respectively. Peripheral LTL was detected by lfuorescent quantitative analysis, the relationship between LTL and PCAD with inlfuencing factors were studied by Spearman correlation analysis. Results: In PCAD group, compared with SCAD patients, ACS patients had more male gender, higher Gensini score, lower T/S ratio and shorter LTL, allP<0.05. Compared with Non-CAD group, PCAD group had decreased T/S ratio (0.88 ± 0.86) vs (1.10 ± 0.57),P<0.05. T/S ratio was negatively related to age in both PCAD group (r=-0.275,P=0.002) and Non-CAD group (r=-0.316,P=0.000). Spearman correlation study presented that in PCAD group, LTL was negatively related to hyperlipidemia (r=-0.415,P=0.049) and diabetes (r=-0.472,P=0.036); multi linear regression analysis indicated that in PCAD group, LTL was negatively related to age (B=-0.023,P=0.038) and in Non-CAD group, LTL was negatively related to age (B=-0.027,P=0.000), smoking (B=-0.278,P=0.012), HDL-C (B=-0.297,P=0.046). Conclusion: PCAD had more male ACS patients with shorter LTL and severer coronary lesions; LTL was negatively related to hyperlipidemia and diabetes, age was an important inlfuencing factor for LTL shortening.

Background and purpose:Diffusion-weighted whole-body imaging with background body signal suppression (DWIBS) can be used for MR imaging systemic examination, especially the lymph node and bone diseases can be clear, and the imaging result is similar with PET. The aim of this study was to compare the value of clinical application in the diagnosis of malignant metastatic osteopathic between DWIBS and bone scintigraphy mapping. Methods:Thirty-six specimens conifrmed with malignant tumors by the pathology of operation or biopsy underwent both DWIBS imaging and bone scintigraphy mapping, chi-square test was used for comparing the detection results of bone metastasis by this two imaging methods. Results:Thirty (165 positions in all) of 36 malignant tumor patients were conifrmed as having bone metastasis, compared that 26 patients (143 positions) with DWIBS method and 23 patients (132 positions) with bone scintigraphy mapping were detected, but there was no statistical signiifcance between this two imaging methods (χ2=1.002, P=0.506). The sensitivity, positive predictive value (PPV) and accuracy of the detection rate of bone metastasis were similar in DWIBS and bone scintigraphy, with 86.7%, 96.3%, 86.1%and 76.7%, 88.5%, 72.2%, respectively;but the speciifcity and negative predictive value (NPV) in DWIBS (83.3%and 55.6%) was higher than that of in bone scintigraphy (50.0%and 30.0%). The detection rates of different bone metastasis with DWIBS and bone scintigraphy were 86.7%(143/165) and 80.0%(132/165), and it was no signiifcant difference (χ2=2.640, P=0.104);DWIBS method was better than bone scintigraphy in the detection of osseous metastasis on pelvis and limbs long bone, and there was different signiifcant (χ2=6.783 and 7.636, P=0.023 and 0.016). Conclusion:DWIBS could detect bone metastatic lesions effectively, and there is ifne consistency with bone scintigraphy. Therefore, DWIBS is to hope to be extended and applicated clinically.

Background and purpose:Tumor suppressor gene P53 has long been studied in tumors, including breast cancer. More studies focused on the relationship between P53 and prognosis of breast cancer and found that P53 overexpression suggested a bad prognosis. However, the effect of P53 on early stage postmenopausal patients with ER-positive breast cancer has not been clariifed yet. This study was to investigate the role of P53 plays in aromatase inhibitor (AI) resistance among early stage postmenopausal patients with ER-positive breast cancer patients. Methods:A total number of 293 operable breast cancer patients who received surgical treatment during Jul. 2000 to Jul. 2006 in Fudan University Shanghai Cancer Center were enrolled into this study. All patients received AI treatment. The SPSS 12.0 software was used to estimate the survival rate. Univariate and multivariate analysis were also performed via above software. Results:The median follow-up time is 72 months (6-140 months). The 5 year disease free survival (DFS) of P53 positive and negative were 78%and 89%. The results showed that P53 overexpression (HR=1.729, 95%CI:1.038-2.880, P=0.035), pathological stage (HR=2.270, 95%CI:1.399-3.681, P=0.001);histological grade (HR=2.328, 95%CI:1.312-4.133, P=0.004); age (HR=1.988, 95%CI:1.511-2.617, P<0.005) were still the independent risk factors of recurrence and metastasis in breast cancer patients treated with AI. Conclusion:P53 overexpression correlated strongly with AI resistance in early stage postmenopausal patients with ER-positive breast cancer patients who were treated with AI and conifrmed the relevance of previously described prognostic factors. It is reasonable to take P53 expression into account when we evaluate the risk of breast cancer patients and decide the anti-cancer treatment strategy.
