The transvaginal ultrasonography,sonohyterography and intravenous contrast-enhanced ultrasonography are main ultrasonographic methods in evaluation of endometrial lesions.This article introduces the procedures,limitations,advantages and disadvantages of these three ultrasonographic methods in differential diagnosis of benign and malignant endometrial lesions in postmenopausal women.

Objective To study the clinical and MRI features of central pontine myelinolysis(CPM).Methods The MRI findings of 11 cases with central pontine myelinolysis verified by clinic and imagings were analyzed.Results There were history of drink wine long term in 7 cases,undernourishment in 4 cases,low-blood-sodium in 10 cases.Long T 1 and T 2 signal intensity was showed on MR in central pontine,focus presented under cortex cerebri and in nucleus basalis area in 4 cases.3 cases enhanced around focus,2 cases enhanced in center and 4 cases no enhanced on postcontrast MRI.Conclusion There are characteristic MRI features in central pontine myelinolysis,it is not difficult to diagnoses CPM in early stage if its clinical manifestations and testing treatment with hormone is associated with MRI features.

OBJECTIVE:To observe the effect of cefoperazone on the surgical haemostastic outcome so as to offer reference for preoperative anti-infection medication.METHODS:A total of 60 patients undergoing laparotomy were randomly divided into medication group(cefoperazone)or control group.The blood coagulation functional parameter changes of the 2 groups before and after operation were observed,and the intraoperative blood loss volume,blood infusion volume,and the haemostatic time were recorded.RESULTS:The thrombin time,the prothrombin time,partial prothrombin time were all longer,and the intraoperative blood loss volume and blood infusion volume and the haemostatic time were all more in cefoperazone-treated group than in control group(P

Objective:To investigate the clinical effect of enteroclysis of Chinese crude drug in treating different stages of chronic renal failure(CRF).Methods:Forty one inpatients with CRF in the nephrology were summarized,who had taken on the treatment with enteroclysis.At the end of the treatment,the change of symptoms and BUN,Scr,Ccr of the inpatients with CRF were recorded and statistically analyzed retrospectiveiy.Results:The total effective rate of enteroclysis in treating CRF was 58.54%,the patients whose Ccr was at the stage of 20-10ml/min reached 75.00%,while Scr,BUN decreased signifi cantly and Ccr rose markedly(P

Objective To study the effect of early rehabilitation on motor function of hemiplegic patients after cerebral infarction. Methods Forty two patients were divided into two groups randomly: a rehabilitation group and a control group. Both groups were given the same internal medical treatment to stabilize the patients conditions in the early stage. In addition, the patients in the rehabilitation group were given early formal rehabilitation training, while those in the control group were given no formal rehabilitation training. The results of therapy were assessed by using SIAS method (Stroke Impairment Assessment Set). Results As shown by the SIAS result, the scores of motor function, muscle tone, range of motion (ROM), pain, trunk control and function on the unaffected side in the rehabilitation group were significantly better than those in the control group (all P

Objective To investigate the impact of propofol and midazolam on the time course of extubation in patients with mechanical ventilation.Methods The patients were randomly divided into the propofol group(n=37)and the midazolam group(n=52),which were further divided into three sedation stratums.The administration of two drugs were stoped immediately while weaning from the ventilator.The awakening time and extubation time of the two groups were recorded and compared with each other.Results Both awakening time and extubation time of the propofol groups were shorter than those of the midazolam group(P

Aim To investigate the antagonistic action o f total saponins of panaxnotoginseng(PNS) on cardiac hypertrophy and its nervous mechanism.Methods (1)cardiac hypertrophy of rats due to pressure overload was induced by constricting of abdominal aorta. There were five groups in the experiments. The rats in Group A(control group)were sham operated . Group B was aorta-constricted group.The rats in Group C,D,E were given ip PNS 50,100,150 mg?kg?d -1 for three weeks respectively. Three weeks later, We measured the heart-weight(HW),left ventricular weight(LVW), the ratio of HW/BW,LVW/BW (LVI) and the cardiomyocyte diameters(MD) after dyeing by HE color.(2)The effects of PNS on the fast excitatory postsynaptic potential(f-EPSP),membrane depolarization induced by application of acetylcholine (ACh),membrane potential and membrane resistance of the isolated Stellate ganglion(SG)of the rats were investigated by means of intracellular recording techniques. Results (1)HW/BW, LVI and MD of Group E were significantly lower than that of Group B(P0.05).(2)At the concentration of 0.10 ～0.16 g?L -1, PNS reversibly depressed the amplitude of f-EPSP, but the ACh depolarization,membrane potential and membrane resistance were not significantly altered by PNS. Conclusion PNS can prevent cardiac hypertrophy due to pressure overload in rats and this action may underline its inhibitory action on presyn aptic effect of regulating calcium influx.

Tau is a microtubule-associated protein th at can promote micortubulbe polymerization in vitro and can stabilize the asse mbled microtubules. Hyperphosphorylated form of tau comprises the main component of the paired helical filaments and neurofibrillary tangles found in Alzheimer s desease (AD). This paper reviews the functions and the prospects of tau in Al zheimers disease.

Objective To explore the relationship among personality,job burnout and knowledge sharing behavior of the enterprise employees.Methods The 44 items big five inventory(BFI) ,knowledge sharing inventory and job burnout inventory were administrated to 635 employees online.Results ( 1 ) Agreeableness had a significant main effect on knowledge sharing ( β =0.135, P＜0.01); (2)Cynicism( β = -0.140, P＜0.01) and reduced personal accomplishment( β = -0.125, P＜0.01 ) had a significant effect on knowledge sharing behavior and its two dimensions; (3) Job burnout partially mediated the relationship between agreeableness and knowledge sharing behavior(P＜0.01).Conclusion Enterprise employees' personality had different effects on knowledge sharing behavior,and job burnout was an important mediating role in the relationship above.

After an elaboration with the ideas and steps for developing a cross platform acupoint display and re-trieval system using flash technology, how to rapidly locate and display the acupoints and how to search the recent papers on acupoint therapy were described with the Jing-Well Point as an example.
