Objective To investigate the expression changes of hepatic gelsolin (GSN) and the potential effect of traditional Chinese medicine Xuebijing injection in septic rats. Methods A total of 104 male Wistar rats were randomly divided into four groups, ie, normal control group (n = 8), sham operation group (n = 32), cecal ligation and puncture group (CLP group, n = 32) and Xuebijing treatment group (n = 32). The sepsis animal models in the last two groups were developed by CLP. In Xuebijing treatment group, animals were treated intravenously with Xuebijing injection (4 ml/kg) at 2, 12, 24,36, 48 and 60 hours after operation, respectively. Animals were sacrificed respectively at 6, 12, 24, and 72 hours after operation to harvest blood and hepatic tissue samples. Markers of liver function, contents of GSN and Gc globulin and expression of GSN mRNA in the liver tissues were detected. Results Compared with normal control group and sham operation group, hepatic GSN content was decreased significantly at various intervals in CLP group (P ＜ 0. 05), which reached the lowest value of (1.42 ±0.50) ng/mg at 12 hours. Meanwhile, expression of GSN mRNA in the liver was markedly enhanced at six hours after CLP and remained a high value until 72 hours, compared with the sham operation group (1.203±0.053 vs 1.030 ±0.084, P ＜0.05). Similarly, the hepatic Gc globulin contents was increased in the CLP group compared with the normal control group and sham operation group (P ＜ 0.05).After treatment with Xuebijing injection, the hepatic GSN contents at 6-72 hours was increased gradually while serum ALT and AST levels at 6, 12 and 24 hours were reduced significantly in comparison to the CLP group (P ＜ 0.05). Nevertheless, treatment with Xuebijing injection showed no marked effect on hepatic GSN mRNA expression and Gc globulin release (P ＞ 0.05). Conclusions Hepatic GSN contents are persistently reduced in the development of sepsis and treatment with Xuebijing injection can markedly attenuate acute liver injury through increasing GSN contents in severe sepsis.

Based on the theory of organizational performance appraisal and the needs of developing China's hospital performance assessment system, the paper proposed the concept and emphasized the significance of establishing a comparative hospital performance assessment system in China. By sharing identical experiences from overseas, the paper also advocates that as China is building its comparative hospital performance assessment framework, it is imperative to verify the comparability of hospital performance assessment indicators, build a quality-centered comparative model for hospital performance assessment, and a three-tier comparative model to cover hospitals, departments and posts. These efforts will further improve China's performance assessment system.

OBJECTIVETo study the Cupric ion release characteristics of different copper raw materials in intrauterine device in vitro by ICP. Reveal the relationship between purity and shape of Cu-IUD copper and copper ion release.

METHODSAccording to a certain proportion, the copper raw materials were 100 times diluted into the simulated uterine solution at 37 +/- 0.5 degrees C. Replaced medium at certain time points and collected soaking liquid. Using ICP analyzed the concentration of copper ion released.

RESULTSThe largest daily release of copper ions was in the first 7 days. There was no statistically significant difference between the copper ion release amount of 99.99% and 99.95% purity copper wire (P > 0.05). The release of copper ion of the copper wire was far greater than that of the copper pipe in early stage (P < 0.01). The release amount decreased and stabilized at 56 day.

CONCLUSIONRelease characteristics of copper ion could effectively analysis by ICP. And in the same area, the release amount of copper ions of copper wire was greater than that of copper pipe.

Objective To investigate the correlation between body mass index (BMI),waist circumference (WC)and sperm quality parameters of male infertility.Methods 303 cases of male infertility patients including outpatients and inpatients were selected to measure height,weight and WC,and to group according to BMI standards,and sperm quality parameters of each group were detected simultaneously.Results Overweight,obese and severely obese group sperm concentration had very significant difference compared with normal weight group (t = 3.941,3.782,5.632,P <0.01);Overweight,obese and se-verely obese group total sperm count had significant difference compared with normal weight group (t = 2.117,2.655, 8.591,P <0.05 or 0.01).No difference between the normal weight and low weight group (t=0.668,P >0.05),sperm con-centration and total sperm count decreased with increasing BMI.Low weight group,overweight,obese and severely obese group were higher than normal sperm immobile body recombination,there were significant differences (t = 2.847,8.592, 8.472,5.380,P <0.05).Normal sperm morphology rate of abnormal weight and normal weight groups were significantly lower comparison,the difference was significant (t=2.356,5.968,5.156,5.993,P <0.05).Abnormal body weight of each group of sperm motility and normal weight group were significantly lower comparison,and there were significant differences (t=2.847,8.593,8.472,5.380,P < 0.05).Forward movement rate abnormal and normal body weight of each group re-structuring comparison were significantly lower,and there was a significant difference (t=2.432,11.816,9.588,13.528,P<0.05).Overweight,obese and severely obese group of sperm DNA fragmentation index were higher than the normal weight group,which the data showed a significant differences (t=6.168,7.238,9.309,P <0.05),while there was no statis-tical significance between low weight group and normal weight group (P >0.05).Conclusion Studies showed that the ab-normality of BMI and obesity could cause the changes in sperm parameters which might be an important mechanism of male infertility.

Objective To study the effect of high frequency stimulation (HFS) in pedunculopontine nucleus (PPN) on the neuronal activities of globus pallidus internus (Gpi) in Parkinson’s disease (PD) model rats, and the mechanisms there-of. Methods Seventy male Sprague-Dawley rats were divided into two groups, control group (n=30) and PD model group (n=40). PD rat model was established by the injection of 6-OHDA into substantia nigra pars compacta (SNc) on the right side of the brain with stereotactic technique. Electrophysiological recordings were made in anaesthetized rats to investigate the ef-fects of HFS-PPN on the firing rate of the GPi neurons. Brain microdialysis combined with high-performance liquid chroma-tography was applied to detect glutamate (Glu) andγ-aminobutyric acid (GABA) levels in GPi. Results HFS-PPN caused an excitatory reaction of the majority of neurons recorded in the GPi in PD model group and control group. The mean firing rate of GPi excited neurons was significantly increased (P﹤0.01). The levels of Glu were reduced under HFS-PPN and the levels of GABA were not affected (P>0.05).Conclusion HFS-PPN heightened the electrical activity of GPi neurons and re-duced the level of Glu. These excitatory effects were probably realized by PPN-GPi direct path or other indirect path.

Objective To explore the mechanism of the low-frequency electrical stimulate on pedunculopontine nu-cleus to treat the Parkinson (PD) through observinge the low-frequency electrical stimulation of Pedunculopontine Nucleus (PPN) in PD rat model and the effects of neurotransmitters (GPi) neurons discharge in the medial part of the globus pallidus. Methods Thirty SD rats were randomly assigned to the control group and the PD model group, with 15 in each group. PD model was established through injecting 6-OHDA into Substantia nigra compact (SNc) of black rat. Effect of low frequency electrical stimulation, micro-electrophoresis glutamate (Glu) and its receptor blocking breaking agent MK-801,γ-aminobu-tyric acid (GABA) and its receptor antagonist bicuculline (BIC) on discharge of rat neuron GPi was examined using extracel-lular unit recording methods through seven glass microelectrode recording. Results When stimulated by low frequency electrical stimulation of PPN, reactions from the control group and neuronal response GPi in PD rats were inhibited. The aver-age discharge frequency was reduced compared to pre-stimulation (P < 0.01). Micro-electrophoresis and BIC Glu excite neurons while microiontophoresis MK-801 and GABA restrain neurons. In the background of micro-electrophoresis BIC’s excitatory effects on neuron, low-frequency electrical stimulation on PPN reduced neuronal firing frequency. And in the background of inhibition effect of micro-electrophoresis MK-801, low-frequency stimulation PPN further restrain neuronal discharge frequency. Conclusion Low frequency electrical stimulation inhibits GPi PPN neuronal activity probably though regulating neurons projecting to the Glu and GABA nerve pathways in GPi neuron.
