This paper analyzes the disqualification factors influencing B-D test results by using B-D test monitoring. Effective methods were taken to remove them and the problems were found in time for overhauling the sterilizer. The forevacuum steam sterilizer should be kept in good state and regulated strictly so that it can work in program with qualified sterilizing quality,thus ensuing a safe and reliable clinical application.

Our study was based on the book Theory of Epidemic Heat Syndrome. This book was written by Mr. Shao Dengying of Qing dynasty, who was famous in Qing Dynasty on curing virus infection. We described his unique insights in diagnosis and treatment of epidemic heat syndrome in six aspects: the origin, position of epidemic heat invasion, difference between epidemic heat syndrome and typhus, paying attention to the symptoms of epidemic heat, differentiation and treatment from qi, bloods and stomach, and attaching importance to the stomach Qi and kidney essence etc.

Objective To study the clinical significance of routine MRI and 3 dimensional time of flight magnetic resonance angiography (3D-TOF-MRA) for the pathogenesis of Trigeminal neuralgia (TN) Methods 32 patients with TN and 32 controls were observed by MRI and 3D-TOF-MRA by the enhancement of DTPA Diagnosis of the presence of compressions in the root exit zone (REZ) of the Trigeminal nerves were carried out by two radiologist on an independent console Results (1) In patients studied, compressions of the REZ of the nerves were detected with 29 on symptomatic sides (90 63%), neurovascular on 25 sides and tumor on 4 sides, and 2 on the asymptomatic sides(6 25%, all neurovascular) In the controls, 3 sides (4 26%, all neurovascular) were involved in the compressions of the REZ of the Trigeminal nerves (2) In 25 cases with TN of neurovascular etiology, the offending vessels were the superior cerebellar arteries in 17 cases (68%), anterior inferior cerebellar arteries in 2 cases, vertebral artery (VA) in 1 cases, difficultly identified vessels in 2 cases, vein in 2 cases, vascular malformation in 1 case (3) The RR of microvascular and tumor compressions which cause TN were 36 74 (4) The real microvascular compression and entrapping were only detected on the symptomatic sides of TN in 13 patients (52%) Conclusion MRI and 3D-TOF-MRA appeared to be the best imaging test for the pathogenesis of TN now The major causes of TN might be different neurovascular and tumor compressions in the REZ of the fifth cranial nerve, with real compression, entrapping or tight contact

The liquid-chromatography-mass technology was used in the metabolomic analysis of mouse's blood 1 hour after exhaustive exercise,in order to explore the potential mechanism of Rhodiola in fatigue elimination of exhaustive exercise mouse.The exhaustive mouse model was made by loaded-swimming.A total of 24 mice were randomly divided into theRhodiola + exercise group,exercise group andno-exercise group.The dose of Rhodiola was 0.4375 g·kg-1·d-1.The loaded-swimming was conducted after two successive weeks of medication.Blood was collected 1 h after swimming for the sample preparation.The enzyme assay and anthrone colorimetry were used to test blood lactate acid and glucose,respectively.UFLC-Q-TOF was used to detect metabolic profiles of each group.The principal component analysis (PCA),orthogonal partial least squares discriminant analysis (OPLS-DA) and heat map analysis were used to compare differences among groups with score chart and to obtain the characteristics biomarkers by load chart.The results showed that the blood lactate acid level of theRhodiola+ exercise group was significantly lower than that of theexercise group.And the glucose level of theRhodiola+ exercise group was significantly higher than that of theexercise group.The metabolomic analysis showed that there were no obvious changes on 1,25-(OH)2D3,diacylglycerol (DG) and inositol triphosphate (IP3).All three materials in theRhodiola + exercise group were significantly lower than those of theexercise group.They were much closer to theno-exercise group.And all three materials were related to the increasing of muscle tension.It was concluded that Rhodiola had the function of promoting fatigue eliminating.This effect may be related to cell membrane protection,regulation of 1,25-(OH)2-D3→IP3,DG pathway,and relieving of muscle tension after exercises.

Objective To investigate the role of deoxycholic acid (DCA) in the pathogenesis of Barrett esophagus.Methods Normal human esophageal mucosal epithelial cells were cultured in vitro with defined keratinocyte serum-free media (D-KSFM).The cultured cells were treated with different concentrations of DCA and specific p38 mitogen activated protein kinase (MAPK) inhibitor. The expression of p38,phosphorylated p38 (p-p38) and caudal-related homeodomain transcription 2 (CDX2) at protein level were assessed by Western blot.The correlation between p-p38 and CDX2 was analyzed.The data were analyzed by one way ANOVA and LSD test.Results After being cultured with DCA for 24 h,the expression of p-p38 and CDX2 increased along with the increasing of DCA concentration.Compared with the control group (p-p38 was 13.7％ ± 1.0％ and CDX2 protein was 0),the difference was statistically significant (P＜ 0.05).When DCA was at 500 μmol/L,the expression of p-p38 and CDX2 reached the highest level (44.0％ ± 1.7％ and 8.59± 1.25).After pretreated with SB203580 for two hours and then 500 μmol/L DCA was added into cell culture,both expression level of p-p38 and CDX2 decreased compared with 500μmol/L DCA group (p-p38:28.3％ ±2.2％ vs50.5％±9.5％,CDX2:0.94±0.13 vs 2.31±0.41) after 24 h.Conclusions DCA can induce the expression of CDX2 in normal human esophageal mucosal epithelial cells,which is related with the activation of p38.The phosphorylation of p38 maybe involved in the pathogenesis of Barrett esophagus.

Objective To study the clinical significance of 3 dimensional time of flight magnetic resonance angiography(3D-TOF-MRA) for the pathogenesis of hemifacial spasm (HFS) and trigeminal neuralgia(TN).Methods 48 patients with HFS and 46 patients without HFS and 42 patients with TN and 40 patients without TN were examined by MRI and 3D-TOF-MRA by the enhancement of DTPA. Diagnosis of the presence of compressions in the root exit zone(REZ) of facial nerves and trigeminal nerves were done by two radiologists on an independent console. Results (1)In the patients, compression of the REZ of the facial nerves and trigeminal nerves were detected on 45 spastic sides (93.8%,neurovascular on 44 sides and tumor on 1 side) and 36 spastic sides ( 85.7%,neurovascular on 32 sides and tumor on 4 sides ), 8 and 4 on the asymptomatic sides (16.7% and 9.5%, all neurovascular ). In the controls, 4 and 5 sides ( 4.4% and 6.3% ) were found in the compression of the REZ of the facial nerves and trigeminal nerves. ( 2 ) The offending vessels of compression of the REZ of the facial nerves were the anterior inferior cerebellar artery (AICA) in 17 cases ( 38.6% ), the posterior inferior cerebellar artery (PICA) in 12 cases (27.3%), the vertebral artery (VA) in 6 cases (13.6%). The offending vessels of compression of the REZ of the trigeminal nerves were the superior cerebellar artery ( SCA ) in 18 cases ( 56.3% ), the anterior inferior cerebellar artery in 5 cases (15.6%), the difficult identified vessels (DIV) in 4 cases (12.5%). (3)The relative risks of microvascular compressions which cause HFS and TN were 26.6 and 9.84. (4) The compressions of the REZ of the facial nerves and trigeminal nerves were proved in 4 cases (neurovascular 3 cases and tumor 1 case) and 10 cases (neurovascular 6 cases and tumor 4 casee) in the operation.Conclusion MRI and enhanced 3D-TOF-MRA appeare to be the best imaging technology for the pathogenesis of HFS and TN now. The major causes of HFS and TN may be different neurovascular compressions in the REZ of the facial nerves and trigeminal nerves, some cases are caused by tumor compression.

Objective To investigate the preventive and therapeutic effects of Tiaozhi Baogan Capsule (TBC) on fatty liver in rats and to explore its therapeutic mechanism. Methods SD rat models of fatty liver were set up by feeding high fat diet. After the treatment of TBC, the general physical state, liver index (the ratio of liver weight with body weight) , hepatic pathological changes , blood biochemical indices were observed in model rats. Results TBC could obviously ameliorate liver pathological changes in model rats, relieve hepatic steatosis and hepatocellular necrosis, decrease the content of malondialdehyde( MDA) and increase the vitality of superoxide dismustase (SOD) in serum and liver, lower the content of total cholesterol (TC) and low- density lipoprotein (LDL) in serum and decreae the liver index (P
