It was concluded that this established standard was simple to operate with good stability and reproducibility , which can be used for quality evaluation of Pyrethri Tatsienenis Flos .

Objective To evaluate the effect of antler polypeptides from Cervus elaphus yarkandensis on MC3T3-E1 cells. Methods The concentration of antler polypeptides of Cervus elaphus yarkandensis was measured by BCA protein assay kit. MC3T3-E1 cells were cultured and analyzed by BCIP/NBT chromogenic alkaline phosphatase (ALP) staining kit. After being induced to form mineralized knot, the cells were stained by using Alizarin red staining. Three different concentrations (10, 1.0, 0.1 μg/mL) of antler polypeptides were analyzed by MTT method and micronutrients enzymes standard method to determine the effect of cell proliferation and ALP synthesis. Results The concentration of antler polypeptides was 0.07 mg/mL. The results of in vitro cell activity analysis showed that the positive rate of ALP was 90%and the mineralization knot was stained red. Compared with the control group, the different concentrations of antler polypeptides all showed the function of cell proliferation and the effect was dose-dependent after 3 d and 7 d. Compared with the control group, at the 3 d, three groups of antler polypeptides promoted synthesis and secretion of ALP (P<0.01) and the results showed a dose-dependent effect. Conclusion Antler polypeptides could obviously promote the proliferation of MC3T3-E1 cells and secretion of ALP, which indicated that antler polypeptides have certain effect on osteoporosis.

Objective To analyze the latency of posture evoked response of normal lower limb muscle in different stimulations and explore its influencing factors. Methods The normal lower limb was induced to produce postural evoked response by the dynamic posturography through two kinds of perturbations, the supporting surface rotation stimulation (Toes-up and Toes-down) and the horizontal perturbation stimulation (Forward and Backward). The latencies of tibialis anterior muscle and gastrocnemius muscle were recorded by surface electromyography acquisition system. The differences of the left and right limb, gen-der and height on the latency of postural evoked response were analyzed. Results (1) Under the Toes-up and Backward perturbation, the latency of tibialis anterior muscle was longer than gastrocnemius muscle;under the Toes-down and Forward perturbation, the latency of gastrocnemius muscle was longer than tib-ialis anterior muscle. (2) The latencies of left limb and right limb had no significant difference. (3) The la-tency in male was longer than that in female. (4) The latency gradually increased with the increase of height. Conclusion In the postural evoked response, different perturbations, gender and height have sig-nificant impacts on the latency of posture evoked response of lower limb muscle. However, the effect of height and gender should be not considered referring to the same individual.

Objective:This paper aims to investigate the awareness and demand for medical liability insurance of doctors, and to provide policy recommendations for the further development of medical liability insurance in China. Method:A stratified random sampling survey is conducted on doctors from a Top3 general hospital in Guangzhou, and the relevant departments and individual doctors were interviewed. Results:The higher the risk in a department, the higher their awareness of medical liability insurance becomes;the longer the length of service for a doctor, the more understanding of medical liability insurance the doctor has. Medical liability insurance is generally supported by doc-tors with a strong willingness of demand, but they opinions on bearing and sharing the insurance premium are quite different. Discussion:Doctors still lack sufficient knowledge of medical liability insurance due to the lack of effective publicity. The structural mode of medical liability insurance is still relatively vague, and the government leadership and market operation ability have a serious shortage. Suggestion:This paper suggest to improve the relevant laws and regulations of medical liability insurance, to strengthen government supervision and publicity, to build a reasonable development model of medical liability insurance in line with the national circumstances, and to strengthen an effec-tive combination of government leadership and market operation.

Objective To evaluate the value of real time three-dimensional ultrasound in differentiating benign and malignant breast tumors. Methods One hundred and fifty-three patients with breast tumors were examined with real time three-dimensional ultrasound. The results were compared with post-operative pathological results. Results A sign of malignancy on the coronal plane was observed by three-dimensional ultrasonography,named “sun-like symptom”,because the sign looked like a shining sun:striated hyperechoic or iso-echoic images scattered radially around cancers,together with the distortion of normal tissue.The accuracy of the sign in differentiating benign and malignant breast tumors was 86.93 %( 133/153 ), the sensitivity was 78.38 %( 58/74 ), and the specificity was 94.94 %( 75/79 ). Conclusions Real time three-dimensional ultrasound is a valuable and new technique in differentiating benign and malignant breast tumors.

OBJECTIVE:To provide reference for clinical prevention and treatment of ceftizoxime-induced hemolytic anemia by investigating the situation of ceftizoxime-induced hemolytic anemia. METHODS:Using Chinese and English“ceftizoxime”“he-molysis”and other words as key words,related literatures during 1986-2015 were retrieved from CNKI,Wanfang database and PubMed database. Those literatures were analyzed statistically in respects of general information,clinical drug use and manifesta-tion,occurrence time and outcome,etc. The mechanisms of hemolytic anemia were analyzed to put forward prevention and treat-ment measures. RESULTS & CONCLUSIONS:A total of 11 literatures were retrieved,including 4 foreign literatures and 7 domes-tic ones. There were 15 cases in total,including 5 foreign cases and 10 domestic cases. According to the patient’s age,there were 7 cases of infants,4 cases of the elderly,3 cases of middle-aged people and 1 case of youth. The hemolytic anemia often occurred on the 2-7 day(8 cases). Most of the patients were improved after treatment,but there were 3 patients who died. The mechanism of hemolytic anemia mainly included the production of immune complex and non-immunologic protein adsorption. It is suggested to investigate allergic reaction history,pay attention to sensitization test on skin,select suitable drug dosage and avoid drug combina-tion. The patient’s medications should be monitored closely. Once hemolytic anemia occurs,it should be immediately stop using the drug and take appropriate measures as hormone treatment,comprehensive treatment,blood transfusion treatment,to avoid en-dangering the life safety of patients.
