Objective:To investigate the effects of propofol on cerebrospinal fluid pressure(CSFP),mean arterial pressure(MAP),cerebral perfusion pressure(CPP) and heart rate(HR)during induction of anesthesia in patients underwent intracranial operation. Methods: In 20 patients scheduled for elective craniotomy, an epidural catheter was placed into subarachanoid. Fentanyl(2 ?g/kg), intravenousl Midazolam (0.04~0.05mg/kg) and propofol (2mg/kg) were administered respectively prior to induction of anesthesia. CSFP,MAP,CPP and HR were monitored at 2min,5min after propofol administration and 2,5,10min after another supplementary dose of propofol 1mg/kg addendum during endotracheal intubation. Results: Compared with the preanesthetic baseline values, CSFP, CPP, and MAP all decreased significantly during induction(P

To observe the clinical efficacy of combined acupuncture and Tuina in the treatment of enuresis following occult cleft spine and seek quantified indexes for result assessment, 40 subjects were treated by above methods and B-ultrasonically examined before and after treatment to determine the capacity of bladder and the residual urine inside it. The total effective rate was 90%; there was a difference of the capacity of bladder between before and after treatment (P＜0.05); 11 cases suffered from residual urine, and there was also significant difference of residual urine between before and after treatment (P＜0.01). It is revealed that this method can increase the capacity of bladder and diminish residual urine.

Objective To summarize the analytical results of radioactivity in the food and drinking water nationwide following the Fukushima nuclear accident,and to evaluate its possible contamination to the public health in China.Methods According to the national standard methods and IAEA,FDA correlative references,the scheme was established on sampling and measurements in food and drinking water after the breakout of the accident.The quality control was requested on the sampling,analyses and data report.Results Trace artificial radioactive isotope of 131I was measured in spinach samples on 2 April 2011 in Beijing. Subsequently 131I was found in 10 kinds of growing leaves vegetables (open field)nationwide.The maximum detectable activity of 131I in vegetables was about 3.1 Bq/kg.Since 3 May 2011,the concentration of 131I has been below the detection limits.No artificial radionulide was detectable in all of milk,drinking water and marine products samples during March to December,2011.Conclusions The food and drinking water measurements in China following the Fukushima nuclear accident denoted that the minor amounts of 131I in vegetables might result in very low absorbed dose and induce no impact on human health.The maximum detectable activity of 131I in vegetables was close to that reported in European countries,and much less than that measured in China immediately after the Chernobyl accident in 1986.

Objective To systematically evaluate the short clinical effect of prone position ventilation (PPV) in patients with acute lung injury/acute respiratory distress syndrome (ALI/ARDS). Methods All relative literatures published in the past nine years were searched by computer and hands. Quality appraisal and review data extraction of searched literatures were completed and underwent Meta analysis. Results Eight studies including 184 patients with ALI/ARDS were brought into this Meta-analysis according to the inclusion and the exclusion criteria. Oxygen in artery(PaO2) 、oxygen index (PaO2/FiO2)、pulmonary compliance (C) increased during prone position ventilation, partial pressure of dioxide in artery (PaCO2)、central venous pressure (CVP) 、peak inspiratory pressure ( PIP)、airway resistance (Raw) showed no change, heart rate (HR) and mean artery pressure (MAP) both increased. Conclusions Pulmonary compliance and hypoxemia of patients with ALI/ARDS is improved markedly in PPV. While, due to some limitations of this Meta-analysis, high quality study on PPV is still needed to make clear the clinical effect, mechanism and scientific procedure of PPV and influence of PPV on hemodynamics of patients, so that we can improve the nursing level of patients with ALI/ARDS.

Objective To evaluate the reliability and validity of the Chinese-version Successful Aging Inventory (C-SAI).Methods The C-SAI was translated according to the Brislin translation model,and its reliability and validity was tested in 181 old adults.Results The content validity index for the scale (S-CVI/Ave) was 0.975.Five factors were extracted by principal components analysis which contributed 58.035％ to the variance.The Cronbach α and split-half reliability was respectively 0.832 and 0.871 for the total scale.Conclusions The C-SAI has good psychometric quality and can be used as a measurement tool for the successful aging.

OBJECTIVETo investigate the regulation of Cha Gan Beng Ga on the activity of biomarker PGC-1α in vivo and in vitro, and lay the foundation for studying the efficacy result of Cha Gan Beng Ga on xenograft tumor model and extracting active constituents.

METHOD(1) The coarse powder of Cha Gan Beng Ga was extracted with 70% ethanol solution through heating and refluxing, and finally was used to freeze dry powder. (2) 50 mg x kg(-1) of freeze-dried power was orally administrated to KM and C57BL/6J mice once daily, lasting for 5 consecutive days; different concentrations of extracted materials was given to non-small cell lung cells A549. (3) The expression level of PGC-1α mRNA was quantitatively determined in lung tissue of mice and non-small cell lung cells A549.

RESULTThe expression levels of PGC-1α in lung tissue of different mice strains had an increasing tendency. Furthermore, the expression levels of PGC-1α in non-small cell lung cells A549 also had an increasing tendency, showing dose and time-dependent relationships.

CONCLUSIONMongolian Medicine Cha Gan Beng Ga could induce the over-expression of PGC-1α mRNA in lung tissue of mice and in non-small cell lung cells A549. The present results will lay foundation for studying the efficacy result of antitumor and active constitutes in future.

Objective To evaluate the effect of hydrogen sulfide combined with mild hypothermia on cerebral ischemia-reperfusion (I/R) injury in rats. Methods Eighty male SD rats, aged 3 months, weighing 250-300 g, were randomly divided into 5 groups ( n = 16 each): sham operation group (group S), cerebral I/R group,mild hypothermia group (group M), sodium hydrosulfide group (group NaHS) and NaHS + mild hypothermia group (group NM). In group I/R, M, NaHS and NM, cerebral I/R was induced by occlusion of 4 vessels (cauterization of bilateral vertebral arteries and 15 min occlusion of bilateral common carotid arteries) followed by reperfusion. In group NaHS and NM, intraperitoneal NaHS 14 μmol/kg was injected immediately after reperfusion, while the equal volume of normal saline was injected in the other three groups. At the same time, the rectal temperature was reduced to 32-33 ℃ within 15 min, lasting for 6 h, in group M and NM, while it was maintained at 36-37 ℃by physical method in other groups. Twelve rats of each group were sacrificed after 6 h of reperfusion, and then the hippocampus was removed for determination of the content of H2 S by using spectrophotometer and the expression of p-CREB and BDNF mRNA by using Western blot and RT-PCR respectively. Four rats in each group were sacririced after 72 h of reperfusion and then the hippocampus was removed for microscopic examination. Results The cerebral I/R injury was attenuated in group M, NaHS and NM compared with group I/R, with the slightest injury in group NM. The H2S content was significantly higher in group I/R, M, NaHS and NM than in group S, and in group NaHS and NM than in group I/R and M. The expression of p-CREB and BNDF mRNA was significantly higher in group I/R, M, NaHS and NM than in group S, and in group M, NaHS and NM than in group I/R. The BDNF mRNA expression was significantly higher in group NM than in group M and NaHS. There was no significant difference in the H2S content and the expression of p-CREB and BNDF mRNA between group NaHS and M.Conclusion Hydrogen sulfide combined with mild hypothermia can attenuate cerebral I/R injury by up-regulating the expression of p-CREB and BDNF mRNA in hippocampus in rats.

0.05).⑥ The incidence of MSI at D3S1234,D3S4103,D3S1300 in recurring cases was 83.33 %,but the ratio of MSI inprimary cases was 30.77 %,the former was remarkablyhigher than the latter(P=0.004).CONCLUSION ①Microsatellite analysis showed that both LOH andMSI of FHIT gene existed in laryngeal carcinoma andhypopharyngeal carcinoma,the former was morecommon.② FHIT gene participates the developmenof laryngeal carcinoma and hypopharyngeal carcinoma and may be one of the candidate tumor suppressor genes.③ MSI of FHIT gene may be correlated with recurrence of laryngeal and hypopharyngeal carcinoma.
