Since 1980s,the ultrasonography has been applied to diagnose cruciate ligament injury of the keen joint and undergone continuous development.At present,cruciate ligament injury of the keen joint can be diagnosed by many examination methods,such as X-ray,arthroscopy,magnetic resonance and ultrasonography.X-ray and arthroscopy are invasive.Magnetic resonance is accurate,but expensive.Ultrasonography could clearly display the anatomic and damaged structure of the cruciate ligament.Ultrasonography is an economical,practical,and noninvasive diagnostic method,and it is valuable in diagnosis of the injured cruciate ligamengt of the knee joint.This manuscript comprehensively analyzes the development of functional anatomy,biomechanics,clinical manifestation,type of damage and imaging features of the injured cruciate ligamengt of the knee joint.The imaging examination of posterior cruciate ligament used by high-frequency and low-frequency ultrasound is valuable for diagnosis of injured anterior cruciate ligament.

Objective To analyze the main causes of sources of stress for nurses in cardiovascular department. Methods We selected 110 nurses from three class-one hospitals in Chengdu and divided them into the nurses in cardiovascular department (the research group) and nurses in other departments (the control group). We compared the two groups in the following aspects: family, society, interpersonal relationship, work nature and work strength, continuing education and professional demand. In view of the high spirit stress existed in nurses in cardiovascular department, some corresponding stress-relief strategies were adopted. Results Two groups were statistically different in social, interpersonal relationship, work nature and work strength, continuing education and professional demand. While in the aspect of family, no difference was seen. Conclusions nurses in cardiovascular department had high spirit stress in social, interpersonal relationship, work nature and work strength, continuing education and professional demand. To analyze sources of stress and stress-relief strategy for them could improve physical and psychological health of them and thus enhance nursing quality.

As a treatment of noninvasive,safe,effective,and easy to operate,external counterpulsation has been widely used in the treatment of ischemic heart disease.The treatment mechanism of external counterpulsation may improve collateral circulation and hemodynamics.Therefore,it can provide a new measure for the treatment of cerebrovascular disease.However,the efficacy and safety of external counterpulsation in the treatment of ischemic stroke still need to be confirmed by a large sample clinical trial.

As increasing drugs for targeting therapy aim in clinic, endostatin has become one of hot spots of research on combined treatment of cancer in recent years.

Objective To study the effect of lumbrokinase treatment on hemorheology, glucose and lipids of type 2 diabetes mellitus (T2DM). Methods 76 cases with T2DM whose blood glucose was controlled at FPG<8mmol/L and 2hPG<11mmol/L were involved in the study. All patients were divided into two groups:lumbrokinase (600ku tid for eight weeks) group (n=40) and control group (n=36). The levels of the blood rheology, glucose and lipids were measured. Results The levels of the whole blood viscosity, plasma viscosity, fibrinogen, platelet aggregation rate and triglyceride were decreased in lumbrokinas group as compared with control groups (all P<0.01).There were no differences in FPG and 2hPG between two groups(P>0.05). Conclusions Lumbrokinase can decrease the levels of the blood rheology and triglyceride in T2DM. It may prevent and cure the complication of diabetes mellitus

Objective To evaluate the accuracy of spectral entropy including response entropy(RE)and state entropy(SE)as a new electroencephalographic measure of depth of sedation during general anesthesia.Methods Twenty ASA Ⅰ or Ⅱ patients aged 20-55 yr undergoing elective abdominal surgery were studied.Anesthesia Was induced with intravenous propofol,fentanyl and vecuronium.After tracheal intubation anesthesia was maintained with sevoflurane inhalation and intermittent iv boluses of fentanyl and vecuronium.BP,HR,SpO2,spectral entropy(Datex-Ohmeda)and BIS(Aspect Medical)were monitored during anesthesia.Loss of eyelash reflex and unresponsiveness to verbal stimulus and mild prodding and shaking were considered to be signs of loss of consciousness(LOC).The time of regaining consciousness Was defined as the time when patients started responding to verbal commands.RE,SE and BIS were recorded before anesthesia(baseline),10 min before LOC,immediately after LOC,immediately after tracbeal intubation,1 h after skin incision,10 min before regaining consciousness immediately after consciousness was regained and 10 min after extubation.Results There were sisnificant changes in RE,SE and BIS during the transition from consciousness to LOC.The RE,SE and BIS values for LOC were 76,73 and 68 with sensitivity of 94%,95%and 92%and specificity of 92%,94%and 91%respectively.The accuracy of RE.SE and BIS in predicting LOC was 93%,95%and 94%respectively.The RE,SE and BIS values for regaining consciousness were 82,75 and 70 with sensitivity of 95%,95%and 91%and specificity of 93%,96%and 93%respectively.The accuracy in predicting regaining of consciousness was 98%,96%and 97%respectively.Conclusion Entropy index Can accurately monitor level of sedation during general anesthesia.

BACKGROUND:There are many reports on the effects of low-to-moderate intensity endurance exercise on mitochondrial biogenesis in the skeletal muscle, but there is no understanding about the high-intensity endurance exercise. It has not been reported whether the high-intensity endurance exercise influence the mitochondrial biogenesis in the skeletal muscle through 5′-adenosine monophosphate-activated protein kinase (AMPK)/silent information regulator factor 2 related enzyme 1 (SIRT1) signal molecules. OBJECTIVE: To investigate the effect of AMPK/SIRT1 signaling cascade on the mitochondrial biogenesis in the skeletal muscle during different intensities of endurance exercises. METHODS:Forty-two male Sprague-Dawley rats were randomly divided into sedentary group, moderate-intensity exercise group and high-intensity exercise group. Moderate-intensity exercise load was 28 m/min, 60 min/d;high-intensity exercise load was 38 m/min, 60 min/d. In both exercise groups, the rats had 5 days of exercise and 2 days of rest within 1 week, and the exercise lasted for totaly 7 weeks. The animals of exercise groups were kiled immediately, 6 hours and 24 hours after exercise. Quantitative PCR was used to detect peroxisome proliferators γ activated receptor coativator-1α (PGC-1α) and SIRT1 gene expression, and western blot to detect phosphorylated-AMPK (P-AMPK) and SIRT1 protein expression. RESULTS AND CONCLUSION:(1) Immediately, 6 hours, 24 hours after moderate-intensity exercise, PGC-1α mRNA expression in the skeletal muscle was 362% (P < 0.01), 675% (P < 0.01) and 116% of that in the sedentary group, P-AMPK protein expression was 112%, 165% (P < 0.05), 129% (P < 0.05) of that in the sedentary group, the expressions of SIRT1 protein and mRNA were 55% (P < 0.05), 86%, 103% and 109% (P < 0.05), 155%, 132% (P < 0.05) of those in the the sedentary group, respectively. (2) Immediately, 6 hours, 24 hours after high-intensity exercise, PGC-1α mRNA expression in the skeletal muscle was 274% (P < 0.01), 130% (P < 0.05), 68% (P < 0.05) of that in the sedentary group, the expression of P-AMPK protein was 235% (P < 0.01), 166% (P < 0.05), 160% (P < 0.05) of that in the sedentary group, the expressions of SIRT1 protein and mRNA were 199% (P < 0.01), 166% (P < 0.05), 164% (P < 0.05) and 255% (P < 0.01), 292% (P < 0.01), 122% of those in the sedentary group, respectively. These findings indicate that (1) 7 weeks of moderate-intensity endurance exercise significantly increased PGC-1α gene expression in the skeletal muscle, and its mechanism may involve AMPK/SIRT1 signaling cascade; (2) 7 weeks of high-intensity endurance exercise significantly inhibited PGC-1α gene expression at 24 hours after exercise,and this process was carried out in an AMPK/SIRT1 signal cascade independent manner.
