Objective To compare the clinical effects of combined anesthesia of lumbar plexus-sciatic nerve and superior clunial nerve versus spinal-epidural analgesia in total hip replacement. Methods Fifty cases of total hip replacement were randomly divided into two groups. Patients in group A received combined anesthesia of lumbar plexus-sciatic nerve and superior clunial nerve,while patients in group B received spinal-epidural analgesia. Results There were no significant differences in preoperative HR, SBP,DBP and SpO2 between the groups(P > 0. 05). Compared with pre-anesthesia data,HR,SBP,DBP in group A were significantly lower during the anesthesia(P < 0. 05). In group B,there were no significant changes in HR,SBP,DBP and SpO2 during the anesthesia( P > 0. 05). Patients′ heart rate in group A showed significant changes compared with that in group B. The differences in HR,SBP and DBP between group A and B at the same time points were significant(P < 0. 05). Superior rate of anesthesia in group B is higher than that in group A(P < 0. 05). Conclusion Combined anesthesia of lumbar plexus-sciatic nerve and superior clunial nerve has limited influence on the circulatory and respiratory systems,which can be used for total hip replacement.

Objective To compare the difference in pharmacokinetics characteristics of vancomycin in cerebrospinal fluid between administration by continuous infusion and interim infusion.Methods Twenty postoperative patients in the Department of Neurosurgery of Beijing Tiantan Hospital, Capital Medical University admitted into intensive care unit (ICU) to receive vancomycin for prophylaxis of intracranial infection were enrolled, and they were randomly distributed to a continuous intravenous infusion group and a interim intravenous infusion group, each group 10 cases. In continuous intravenous infusion group, the patients received a loading dose of vancomycin (15 mg/kg) by continuous intravenous pump infusion for 1 - 2 hours followed by 30 mg/kg vancomycin in a constant pump infusion rate for 24 hours; while in interim intravenous infusion group, the patients received 15 mg/kg vancomycin administered by intravenous pump infusion for 1 - 2 hours, once every 12 hours. The concentration of vancomycin in the cerebrospinal fluid at different time points was measured by two-dimensional liquid chromatography (2D-LC) method, the parameters of pharmacokinetics were calculated in the two groups, and the adverse reaction was observed.Results The comparison between the ratio of areas under the concentration-time curves (AUC) and minimum inhibitory concentration (MIC) of the continuous and interim groups showed no significant difference (19.7±14.0 vs. 16.1±6.4,P > 0.05). However, in the continuous intravenous infusion group, the drug concentration reached the peak value (0.96± 0.77)μg/mL at 12 hours, and later revealed a plateau concentration 0.91-0.93μg/mL for 12 hours; while in the intravenous infusion interim group, the drug concentration reached the peak value (0.92±0.47)μg/mL at 16 hours, in the later 2 hours declined to (0.84±0.45)μg/mL, and afterwards still had a tendency of persistent declination. In all the patients, no any adverse reaction related to the drug occurred.Conclusion Continuous intravenous infusion and interim intravenous infusion of vancomycin for the postoperative neurosurgical patients without intracranial infection have the similar efficacy of medication, but the former can achieve the peak concentration faster and later the fluctuation of drug concentration in cerebrospinal fluid is smaller than those in the latter.

This paper was aimed to study the method of rapid determination of total flavonoids in Chrysanthemum of different processing methods by near infrared spectroscopy (NIRS). The Chrysanthemum was dried by three different processes. The three methods were directly drying, drying after steamed and drying after fry, respectively. The determination of total flavonoids in Chrysanthemum by different processing methods was produced by using UV-Vis spectrophotometry. Collecting the NIRS spectra of Chrysanthemum, the quantitative analysis model of total flavonoids content in Chrysanthemum of different processing methods was established by partial least square (PLS) and the model was validated. The correlation coefficient (R2), the root-mean-square error of calibration (RMSEC) and the root-mean-square error of prediction (RMSEP) were 0.996 19, 0.104 and 0.168, respectively. The correlation coefficient of predication (r) was 0.979 3 which state that the prediction was accurate. The method of NIRS had the advantage of fast determination, simple operation and high accuracy of prediction, and could be used for rapid determination of total flavonoids content in Chrysanthemum of different processing methods.

Objective:To investigate the syndromes distribution in patients with dysfunctional uterine bleeding(DUB) related to kidney deficiency, and to provide the basis for standardizing the DUB syndrome differentiation of kidney deficiency. Methods: DUB Patients with kidney deficiency were chosen and accepted epidemical survey through the questionnaire, then the frequency and constituent ratio of each syndrome were calculated. Results: In 612 cases of DUB patients with kidney deficiency, there were 102 patients with simple syndromes covered 16.67%, and 510 patients with compound syndromes covered 83.33%. In patients with simple syndromes, the common syndromes were kidney-yin deficiency(45,44.12%) and kidney-qi deficiency(45,41.18%). And the syndromes of kidney-qi deficiency and kidney-yin deficiency were often respctively complicated with liver stagnation(68,11.09%; 113,18.43%), blood defi ciency(57,9.30%; 99,16.15%) and blood stasis(57,9.30%; 99,16.15%), the syndrome of kidney-yang deficiency usually complicated with spleen-qi deficiency(75,12.23%). The syndrome of kidney-qi deficiency(186,57.23%) was commonly-seen in the patients with ovular DUB, while the syndromes of kidney-qi(146,50.69%) and kidney-yin deficiency(111,38.54%) were frequently-seen in the patients with anovular DUB. Conclusion: In clinic, the compound syndromes were commonly seen in patients with DUB due to kidney deficiency, the complicated syndromes of kidney deficiency were liver stagnation, spleen-qi deficiency, blood deficiency and blood stasis..

AIM: To study the effect of thyroid hormone on the expressional change of myosin heavy chain(MHC) gene in cardiomyocyte induced by angiotensinⅡ(AngⅡ) and its potential mechanism. METHODS: Cardiac myocyte was cultured according to the method of Simpson. 10 -8 mol/L T_3 and 10 -7 mol/L AngⅡ were added to the culture medium,respectively or synchronously. After 48 h,the expression of ? and ?-MHC mRNA in myocytes were detected by RT-PCR. The protein kinase C activation were detected by PepTag non-radioactive PKC assay. The incorporation of -Leucine and -thymine to test the protein and DNA synthesis in myocytes were also performed. RESULTS: AngⅡalone increased the incorporation of -Leucine of myocytes while it had no effect on the incorporation of -thy mine. The expression of ?-MHC mRNA was increased and the expression of ?-MHC mRNA was decreased significantly at the condition of AngⅡ. The enhanced PKC activation was induced by AngⅡalso. When AngⅡand T_3 were added to the culture medium synchronously,though the incorporation of -leucine and -thymine were not changed compared with AngⅡ treated alone. The ?-MHC mRNA expression was increased and the ?-MHC mRNA expression was decreased significantly. The PKC activation of the myocytes also was decreased. CONCLUSIONS: T_3 inhibited the expressional change of myosin heavy chain gene in cardiac myocytes induced by AngⅡ. The effect of T_3 on the change of PKC activation in cardiac myocytes may be one of its mechanisms.

AIM To study the anti atherogenesis action of sodium ferulate and its mechanisms. METHODS Atherosclerotic rabbit models were duplicated by feeding high lipid forage and ECV304 were cultured with the hyperlipidemic serum. The atherosclerotic plaque area was measured. Scanning electron microscope, spectrophotometer and immunocytochemical methods were used to detected the microstructures of endothelial cell, the content of NO in suspension and the expressions of TGF? 1, bFGF on the cell surfaces. RESULTS Sodium ferulate could decrease the plaque area, lessen the damnification of endothelial cell induced by HLS, enhance the expression of TGF? 1 and the release of NO from ECs, and reduce the expressions of bFGF in ECs, significantly. CONCLUSION Sodium ferulate can decrease the atherosclerotic plaque area induced by hypercholesterol, which may be relate to the expression change of cytokines.
