Pharmacologic experiments, such as the time of survival of mice in shortage of oxygen in normal pressure, the antagonistic effect on arrhythmia induced by chloroform and the diuretic effect were carried out with LD. Variance analysis, canonical correlation and stepwise regression analysis were applied to interelationship between the amount of each drug and the pharmacologic data. Then, the fingerprints of the solutions were tested by HPLC method and 50 chromatographic peaks were obtained. Correlation and regression analysis was applied to interelationship between the area of each peaks and the pharmacologic data.Results: The results confirmed the poria and cinnamon twig are the basis, while ovate atractylodes and licorice are the adjuvans. 17 peaks, which were established as the therapeutical basis of the decoction, were selected from all compounds, and cinnamic acid of cinnamomum cassia, glycyrrhizin of Glycyrrhiza uralensis and dehydrotumulosic acid of Poria cocos were selected as the markers to evaluate the quality of the decoction.Conclusion: This study provided a significant try of studying the compatibility of composite herbal medicines.

AIM: To clarify the possible mechanism of decrease in coronary flow (CF) after long-term hypothermic storage of the isolated rat hearts. METHODS: The isolated rat hearts preserved in different solutions (SDMC-1,2 S., Stanford S., Collin's S.) at 0℃ for 8 hours were reperfused with 5-hydroxytryptamine (5-HT)(10 -4 mmol/L) and adenosine(Ade)(5 mmol/L) respectively, and the coronary flow(CF), coronary vascular resistance(CVR) and the weight of heart were measured before and after reperfusion. RESULTS: CF decreased while CVR increased in all groups after storage-reperfusion. When endothelium-dependent vasodilator (5-HT) was used, CF in SDMC-2 group was highly increased and CVR decreased. Whereas CF was significantly decreased and CVR increased in Collin's group( P

OBJECTIVETo explore the eyelid's characteristics of outpatients who visited the plastic surgery clinic in 3rd Hospital of Peking University.

METHODSFrom Jan. 2007 to Feb. 2011, we collected facial images and general data of 2,183 outpatients, and divided them into groups according to their genders. The eyelid images were analyzed and epicanthus or foldless eyelid were recorded. Then the incidence rates of epicanthus and foldless eyelid were calculated.

RESULTSIn 2,183 patients (4,366 eyes), the incidence rate of epicanthus is 86.1% (3,760/4,366), and the incidence rate of foldless eyelid is 35.3% (1,541/4,366). In 178 males (356 eyes) and 2,005 females patients (4,010 eyes), the incidence rates of epicanthus are 78.4% (279/356) and 86.8% (3,481/4,010), respectively. The incidence rates of foldless eyelid are 48.0% (171/356) and 34.2% (1,370/4,010), respectively.

CONCLUSIONSThe incidence rates of epicanthus and foldless eyelid are relatively high for the outpatient population in the plastic surgery clinic of Third Hospital of Peking University.

Objective To investigate the clinical efficacy of sequential acupuncture in treating post-stroke dysphagia. Methods One hundred and ten patients with post-stroke dysphagia were randomly allocated to treatment and control groups, 55 cases each. The control group received routine medication and the treatment group, “cortex-pharynx-tongue root” sequential acupuncture in addition. The pre-/post-treatment difference in the Kubota’s water drinking test score was observed in the two groups and the clinical therapeutic effects were compared between the two groups after 14 days of treatment.Results There was a statistically significant pre-/post-treatment difference in the Kubota’s water drinking test score in the two groups (P<0.01,P<0.05). There was a statistically significant post-treatment differences in the Kubota’s water drinking test score between the treatment and control groups (P<0.05). The total efficacy rate was 89.1% in the treatment group and 67.3% in the control group; there was a statistically significant difference between the two groups (P<0.05).Conclusion Sequential acupuncture is an effective way to treat post-stroke dysphagia.

Objective:To analyze the result of smooth pursuit test(SPT) in unilateral vestibular peripheral vertigo and investigate its influencing factors.Method:Smooth pursuit test (SPT) and spontaneous nystagmus (SN)were examined in one hundred and eighty-five patients with unilateral peripheral vertigo(case group) and 51 normal persons(control group) by Video-Nystagmography (Synapsys, France), and the gain of SPT and SN were selected as the observation parameters in order to analyze the waveform and gain of SPT and the relativity between SN and the gain of SPT.Result:Of the 185 patients, 105(56.8%),72(38.9%) and 8(4.3%) cases producedⅠ,Ⅱ and Ⅲ waveforms respectively. Of these patients, 58(31.4%) demonstrated SN and none had Ⅳ waveform. While of 51 normal persons, 38(74.5%), 13(25.5%) persons producedⅠand Ⅱwaveforms repectively and there were no Ⅲ, Ⅳ waveforms or SN. There was statistical significance between the stong and weak gain of SPT in these two groups. Weak gain was significantly different between two groups. The stong and weak gain of SPT in case group were 0.86±0.06,0.80±0.06; 0.78±0.09, 0.65±0.1; 0.68±0.13, 0.45±0.12. The relativity between SN and the gain of SPT was positive when they had same direction(r_s=-0.63,P＜0.05)and negative when opposite (r_s=0.34,P＜0.05).Conclusion:Ⅰ,Ⅱ,Ⅲ three waveforms of SPT could appear in unilateral vestibular peripheral vertigo and the corresponding gains are gradually decreasing.SN is the influencing factor of SPT.

We used metabolomics to investigate the ability of a traditional Mongolian medicine called modified Tabusen-2 (MT-2) to improve kidney yang deficiency (KYD) in rats. All animal experiments were conducted under the guidance and standards of the Medical Ethics Committee of Inner Mongolia Medical University. SD rats were divided into 6 groups of six rats: a normal group, a model group, Jinkuishenqi pill administration group (1.26 g·kg^-1), and MT-2 administration in high-, medium- and low-dose groups (1.512, 0.756, and 0.378 g·kg^-1). KYD was established by intramuscular injection of hydrocortisone (HC) and biochemical indicators and clinical characterization was used to confirm that KYD was established. All groups received intragastrically administered drug (Jinkuishenqi pill or MT-2) or saline. Serum from each group was collected after 8 weeks and analyzed by UPLC-Q-exactive-MS to measure various biochemical indicators. The biomarkers affected by MT-2 were identified and the metabolic pathways of KYD regulated by MT-2 were analyzed by metabolomic analysis. The results show that MT-2 can decrease serum creatinine (Cr) in KYD rats and significantly increase (P<0.05) the content of thyroid stimulating hormone (TSH) and luteinizing hormone (LH). In serum samples, 38 biomarkers such as corticosterone, L-phenylalanine, and DL-tryptophan were measured as possible indicators for disease development in KYD rats. MT-2 lowered 18 biomarkers of KYD, including corticosterone, deoxycorticosterone, and L-phenylalanine, and altered 13 related metabolic pathways including phenylalanine, tyrosine and tryptophan biosynthesis, phenylalanine metabolism and steroid hormone biosynthesis, resulting in an overall improvement in KYD. MT-2 appears to be important in improving KYD in rats mainly by regulating metabolites such as amino acids, steroids and lipids.

Objective To evaluate the effieaey of test bolus technique with multi-slice spiral CT (MSCT) for determining the optimal scan delay time in CT Hepatic artery (HA)-portal vein (PV) angiography and multi-phase scanning.Methods MSCT liver angiography and multi-phase scanning were performed in 187 patients divided randomly into two groups.In group A (n =59),the scan delay time was set according to the subjective experiences of operators; in group B (n=128),the scan delay time was determined by test bolus technique.Abdominal aorta and superior mesenteric,vein were selected as target blood vessels,and 50 HU was set as enhancement threshold value.20 ml contrast agent was injected intravenously and time-density curve of target blood vessels were obtained,then HA-PV scanning delay time were calculated respectively.The quality of CTA images obtained by using these 2 methods were compared and statistically analysed using Chi-square criterion.Resuits For hepatic artery phase,the images of group A are:excellent in 34(58%),good in 17(29%),and poor in 8 (13%),while those of group B are excellent in 128( 100%),good in 0(0%),and poor in 0(0%).For portal vein phase,the images of group Aare:excellent in 23(39%),good in 27(46%),and poor in 9(15%),while those of group B are excellent in 96 (75%),good in 28 (22%),and poor in 4 (3%) respectively.There was statistically significant difference between the ratios of image quality in group A and group B (X2=14.97,9.18,P < 0.05).Conclusion Accurate scan delay time was best determined by using test bolus technique,which can improve the image quality of liver angingraphy and multi-phase scanning.

OBJECTIVETo investigate the effect of nerve growth factor (NGF) on lipopolysaccharide (LPS) injury and activation of nuclear factor-kappa B in PC12 cells.

METHODSIn order to set injury models, the PC12 cells were incubated in different concentration of LPS. Cells were cultured in the culture and were reduced by LPS, and then cells were treated by NGF of various concentrations. The cell viability was determined by methyl thiazolyl tetrazolium (MTT) assay, cellular morphology was observed under inverted microscope and fluorescence microscope, and the content of NF-kappaB was assessed by RT-PCR.

RESULTS(1) The viability of PC12 cell was decreased with concentration of LPS increasing. (2) The cellular morphology change showed that NGF had an ability to reduce LPS injury. (3) The result of RT-PCR showed that the content of NF-kappaB in LPS injury was more than the normal and treated cell, and the treated one was close to the normal one.

CONCLUSIONThe reports about NGF in brain cells repair after inflammatory are very small. And our study is about that NGF can protect the PC12 cell from LPS injury, and this mechanism possible bears on the activation of NF-kappaB.
