Objective To reduce the feasibility of combining the two fall assessment scales in nursing patients..Methods Two nurses were assigned to conduct the assessments among 60 senile patients using Morse assessment scale and Hendrich Ⅱassessment scale to screen patients with high-risk fall.Result The number of high-risk patients using Morse assessment scale was larger than that using Hendrich II assessment scale(P<0?05) Conclusions The combined use of Morse fall assessment scale and HendrichⅡfall assessment scale may make up the shortcomings of each other,assess the risk factors and predict the high risk factors.

BACKGROUND: Biliary ischemia-reperfusion injury is one of the main reasons for the injury bile duct following liver transplantation, liver resection and hepatic artery thrombosis after chemotherapy. However, nothing has been decided yet concerning liver can tolerate long intrahepatic bile ducts ischemia under normal temperature. OBJECTIVE: To use the rabbit biliary ischemia-reperfusion injury, model, analyze the rabbit intrahepatic bile ducts ischemia security time. METHODS: Rabbits were randomly divided into sham operation, hepatic artery and common bile duct joint blocking 1.5, 2, 2.5, 3 h groups. Sham operation group only free common bile duct, hepatic artery and portal vein. Hepatic artery and common bile duct joint blocking 1.5, 2, 2.5, 3 h groups, left and right hepatic duct openings superior margin was clamped using artery clamps, and hepatic artery, common bile duct and loose connective tissue were occluded. Following 1.5, 2, 2.5 and 3 hours, artery clamps were removed to recover hepatic artery or biliary tract blood flow. After a week, animal survival was calculated and liver function was tested. RESULTS AND CONCLUSION: None animals in the sham operation and hepatic artery and common bile duct joint blocking 1.5 hour groups died;survival rate was 87.5% following 2 hours of blocking. Animal survival rate was decreased gradually with prolonged blocking time of blood flow. These indicated that the maximum safety time of blocking biliary duct blood flow was 2 hours. Pathological and histological changes were mild within 2 hours of blocking, mainly presenting cell edema and inflammatory cell infiltration, and necrotic focus was punctiform or fragmentis, reversible. While ischemia above 2 hours, bile duct epithelial necrotic shape was significant. The obvious, hepatic necrosis was multifocal, flake, irreversible damage. Histological change also confirmed that 2 hours may be maximum security limitation of rabbit tolerance intrahepatic bile duct flow blocking under normal temperature.

Chronic active Epstein - Barr virus infection(CAEBV) is an uncommon outcome of EBV infection and may present as severe of fulminant syndrome with high- mortality. It is characterized by chronic or recurrent infectious mononucleosis-like symptoms persisting over a long time and by an unusual pattern of anti-EBV antibodies. Although it occurs in immunocompetent individuals, a number of subtle immunologic defects have been reported in patients with CAEBV. Up to now, there are still no diagnostic criteria of CAEBV in China,so the author introduce it with respect to its diagnosis,history,pathogenesis and therapeutic approaches.

Objective To establish an external calibration method of atomic absorption spectrometry-graphite furnace for determination of heavy metals Pb,Cd,Sb in tetracaine hydrochloride injection.Methods Microwave digestion for the pretreatment method was used,three kinds of heavy metal elements were determined by graphite atomic absorption spectrometry-graphite furnace Results The linear ranges of Pb,Cd,Sb were 0-80.0 ng/mL,0-2.0 ng/mL,0-40.0 ng/mL,therecovies were 92.7%-105.7%,95.8%-103.4%,92.1%-103.5%,respetively.The relative standard deviationless than 6.0%(n=9).Conclusion The method is simple and accurate,which can be used for the control of Pb,Cd,Sb in tetracaine hydrochloride injection.

BACKGROUND:COX-2 gene actual y exists in the joint fibroblast-like synoviocytes, it affects osteoarthritis occurrence and development. Understanding the differences of COX-2 gene expression levels at different stages of osteoarthritis synoviocytes has important theoretical significance for the occurrence and development of osteoarthritis, as wel as the role of synoviocytes in this process.
OBJECTIVE:To analyze the difference of COX-2 mRNA at different stages of osteoarthritis fibroblast-like synoviocytes.
METHODS:Synovial membrane from 44 osteoarthritis patients and 12 normal cases were selected. Primary cells were cultured to passage 4 fibroblast-like synoviocytes for the use in the experiment. COX-2 mRNA expression in osteoarthritis fibroblast-like synoviocytes and normal fibroblast-like synoviocytes was detected using real-time fluorescence quantitative RT-PCR. The relative quantitative analysis was performed using 2-ΔΔCt method.
RESULTS AND CONCLUSION:Expression of COX-2 mRNA in osteoarthritis fibroblast-like synoviocytes was significantly higher than that in normal fibroblast-like synoviocytes (P<0.05). The expression levels reached a peak at early osteoarthritis group, with significant differences compared with middle and late osteoarthritis groups (P<0.05). There was no significant difference between middle and later osteoarthritis groups (P>0.05). COX-2 mRNA might be important biological marker for the inflammation in osteoarthritis, and mainly plays a role in early osteoarthritis stage.

MicroRNAs (miRNA) plays an important role in biological development and disease occurrence and development, and acts as a "main switch" in biology. Among patients of essential hypertension, around 1/3 would suffer left ventricular hypertrophy (LVH). Hence, essential hypertension becomes an independent risk factor for cardiovascular diseases. And miRNAs plays an important role in the occurrence and development of LVH. This paper reviewed the role of miRNA in regulating the stress signaling pathway, defined its impact on the occurrence of LVH, and further emphasized the opportunities and challenges of miRNA as a biomarker and therapeutic target.

We describe the prenatal diagnosis and postnatal follow-up of a fetus with a pericallosal lipoma diagnosed by MRI. The pregnant woman was admitted to Zhongnan Hospital of Wuhan University in February 2019. MRI examinations with multiple sequences and imaging methods were performed prenatally at 31 +6 and 38 +3 weeks of gestation, and at two days and three months postnatally. The MRI images showed that the corpus callosum was normal and the lesion was located around the corpus callosum, with high signal intensity on T1 weighted imaging, medium-to-high signal intensity on T2 weighted imaging, and low signal intensity on fat suppression sequence. No abnormal blood vessels were found on susceptibility-weighted imaging and time-of-flight magnetic resonance angiography sequences. Based on the prenatal and postnatal MRI findings, the tumor was clinically diagnosed as a pericallosal lipoma.

Objective To investigate the relationship between in vivo anti-tumor efficacy of Shenqi injection and its effect on immunologic function in H22 tumor-bearing model mice,and explore the cellular immunologic mechanism of Shenqi injection in inhibiting tumor growth.Methods Three different doses of Shenqi injection were given to H22 tumor-bearing model mice in treatment groups.The tumor growth inhibitory rate(IR) and the index of phagocytosis of peritoneal macrophage were calculated.MTT assay was used to observe the effect of Shenqi injection on spleen lymphocytes stimulated by ConA in vitro separated from H22 tumor-bearing mice.Murine serum IL-2 and IFN-? were detected by means of ELISA assay.Results IR was significantly reduced in two treatment groups compared with that of the model mice(60.72%,48.65%,P

AIMTo study the protective effect of sodium oxybate (SO) against focal cerebral ischemia-reperfusion injury in rats, and the relationship between the effects of SO and ?-aminobutyric acid (GABA). METHODSThe reversible middle cerebral artery occlusion (MCAO)model in rats was established to investigate the role of SO. The scores of neurological deficits was detected by Longa EZ method in MCAO rats. The extracellular levels of glutamate (Glu) and GABA in CSF were measured by high performance liquid chromatography-fluorometer (HPLC-FR) method, and the weight of cerebral infraction was detected. RESULTSThe scores of neurological deficits and the weight of cerebral infraction markedly decreased by SO while the ratio of GABA/Glu obviously increased administered SO in MCAO rats. CONCLUSIONSSO could prevent MCAO rats from ischemia-reperfusion injury, the protective effect is related to SO keeping dynamic balance of excition-inhibition, and persisting inhibition-depended effect.
