AIM: To establish the method of determining cinobufagin and resibufogenin in Xinkening Capsules(Venenum Bufonis,etc.). METHODS: HPLC was applied to determining cinobufagin and resibufogenin.The determination was carried out using an ODS column with a solvent system: methanol-water(50∶40).The flow rate was 1.0 mL/min,detection wavelength was at 296 nm. RESULTS: The linear ranges of cinobufagin and resibufogenin were 3.5 ?g-0.28 ?g and 3.75 ?g-0.30 ?g,respectively.The average recoveries of cinobufagin and resibufogenin were 99.86%(RSD=1.8%,n=5),and 99.84%(RSD=1.2%,n=5),respectively. CONCLUSION: This method is simple,accurate with strong specificity and can be used to control the quality of Xinkening Capsules.

Objective To observe the adjuvant therapy efficacy of Saccharomyces boulardii sachets in liver cirrhosis patients with spontaneous bacterial peritonitis(SBP).Methods 72 liver cirrhosis patients with SBP were randomly divided into the observation group and control group.The patients in the control group (30 cases) were giv-en routine medical treatment such as anti-infection,correction of hypoproteinemia,liver protection,and diuresis,etc. At the base of the control group,the patients in the observation group (32 cases) were orally given Saccharomyces boulardii ( Baili Pharmaceutical Factory,French) 0.5g for one time,two times daily for 10 days.The changes of serum interleukin-6(IL-6),pmcalcitonin (PCT) and hypersensitive c-reactive protein (hs-CRP) levels in the two groups were observed and compared before and after treatment, and curative effect and safety were also observed. Results Before treatment,the serum IL-6,PCT and hs-CRP levels in the two groups had no obviously statistical difference(all P>0.05),but after treatment,the serum IL-6,PCT and hs-CRP levels of the observation group were much lower than those of the control group[(60.50 ±19.10) pg/mL vs (98.32 ±17.20) pg/mL,(1.80 ± 0.34)μg/L vs (6.38 ±3.56)μg/L,(6.20 ±4.15) mg/L vs (20.28 ±8.30) mg/L,t=8.147,7.246,8.529,all P<0.01].Meanwhile,the total effective rate of the observation group was significantly higher than that of the control group(93.75%vs 73.33%,χ2 =4.771,P<0.05).The incidence rate of DAR between the two groups had no obvi-ously statistical difference(9.38% vs 13.33%,χ2 =0.242,P>0.05).Conclusion Saccharomyces boulardii can significantly reduce serum IL-6,PCT and hs-CRP levels of liver cirrhosis patients with SBP,and reduce inflamma-tion reaction to control development of SBP.

Objective To investigate the possibility of early diagnosis of colorectal cancer by combined detec-tion of tumor markers dermcidin(DCD),CA199,CA724 and CEA. Methods We selected 81 colorectal cancer patients and 30 healthy individuals. Serum levels of DCD were detected by ELISA,and serum levels of CA199, CA724 and CEA were detected by electrochemical luminescent immunoassay,and the expression of DCD in colorectal cancer tissue and para-carcinoma tissue was measured by Western blot. Results Serum levels of CA199,CA724,and CEA were significantly higher in colorectal cancer patients than in healthy individuals(P<0.001). Combined detection of DCD,CA199,CA724 and CEA had a greater AUC(0.942)for identifying colorec-tal cancer from the controls. The expression of DCD was significantly higher in colorectal tissue than in para-carci-noma tissue(P<0.05). Conclusions Level of DCD expression was significantly higher in colorectal tissue than in para-carcinoma tissue. Expressions of serum DCD,CA199,CA724,and CEA may be a marker in diagnosis of can-cer,with higher clinical value for the adjuvant diagnosis of colorectal cancer.

Objective To observe the protective effect of?-asarone,the active components from Rhizoma Acori Tarinowii,on human umbilical venous endothelial cell strain ECV304 injury induced by oxidized low-density lipoprotein(ox-LDL)and to investigate its influence on proliferation of vascular smooth muscle cells(VSMC). Methods The well-grown ECV304 cells were randomized into 5 groups:normal group,control group,high-, middle-and low-dose?-asarone groups.Except the normal group,ECV in the other groups were co-cultured with ox-LDL 25?g/mL,and the?-asarone groups were additionally with?-asarone 30,15 and 7.5?g/mL added respectively.Flow cytometry was used to detect the cell apoptotic rate and the mitochondrial membrane potential (MMP)of ECV304 as well as the proliferation index and the DNA content in different cell phases of VSMC. Results In the model group,the apoptotic rate of ECV was increased,MMP was decreased,and VSMC proliferation was promoted(P

Objevtive To investigate the safety of laparoscopic resection and ~(125)I seed implantation for recurrent gynecologic malignancies. Methods Laparoscopic surgery and ~(125)I seed implantation were used in five patients. All complications were recorded. Environmental radiation dose was detected at different distance from radioactive source and different time after operation with-γ-ray equipment. Results The procedure was safely achieved in all five patients. No serious complication was found. All patients experienced slight pain at the implant site and temporary vulva dropsy. With the increase of the distance from radioactive source and time passing, the radiation dose decreased quickly. The detected dose was close to a natural background radiation dose at the distance of 50cm from radioactive source and after 6 months. Conclusions Laparoscopic resection and ~(125)I seed implantation are safe to patient and environment.

Objective To investigate the influencing factors of pain and the changes of vital signs in newborn infants. Methods Forty two newborn infants were rated by the behavioral scale of acute pain in newborn infants. The scores of pain were compared among infants with different gender,gestational age,birth weight,birth age,type of puncture and whether by vaginal birth or not. At the same time,the respiration rate,heart rate,blood pressure and oxygen saturation (SO2)were dynami-cally recorded by the multi-function monitor in the process of puncture. Results The average score of pain was 7.6. There was no significant difference among newborn infants with different gender,gestational age,birth weight and type of puncture(P> 0.05),while significant differences among infants with different birth age and whether by vaginal birth or not (P=0.015 and 0.043 respectively). In the process of puncture,the SO2 was significantly decreased,while the respiration rate,heart rate,sys-tolic and diastolic blood pressure were significantly increased. Conclusions Pain is prevalent in newborn infants and accom-panied by obvious changes of vital signs. The means of childbirth and birth age have significant influence on the neonatal pain. It is suggested to pay close attention to the neonatal pain and take effective interventions.

This study was aimed to investigate the congenital constitution terms consist of Bing and connotation in medical books before Qing dynasty. By searching the character Bing as a keyword in the Encyclopedia of Tradi-tional Chinese Medicine (TCM), 6480 articles were retrieved. Through reading each of the articles, 9 congenital con-stitution terms were concluded. The results showed that Sui dynasty recorded the earliest congenital constitution term. And till the end of Ming dynasty, altogether 9 terms, which were Bing Qi, Bing Zhi, Bing Shou, Bing Fu, Suo Bing, Fu Bing, Qi Bing, Bing Ti and Su Bing, appeared in sequence. The terms appeared with high frequency were Bing Shou ( 33 . 27%) and Bing Fu ( 32 . 99%) . There were 5 congenital constitution relat-ed factors altogether , which were physique , parental heredity , life span , qi and blood as well as region , ap-peared in sequence . And the term appeared with high frequency was physique ( 32.11%) . It was concluded that before Qing dynasty, all congenital constitution terms occurred with the character of Bing (endowment). The usage of different terms to state congenital constitution was intended to describe different associated factors . It reflected the understanding of congenital constitution process. The first known congenital constitution factor was not parental heredity but physique . Qi and blood was the second most appeared factor . This indicated that con-genital constitution does not only involve the structure of the body ( physique ) , but also the function of the body (qi and blood). The investigation about congenital constitution of ancient TCM brings a positive practical signifi-cance for the modern health cognition and health maintenance .

Purpose To quantitatively evaluate longitudinal strain and strain rate (SR) of left ventricular (LV) in normal infants and young children using velocity vector imaging (VVI). Materials and Methods A total of 50 normal infants and young children were enrolled in the study. The longitudinal strain peaks and SR peaks in three sections of LV walls during systole period and relaxation period were measured by VVI from apical four-chamber view, apical two-chamber view and long axis view, respectively. Results Forty-one cases (82%) presented a smooth strain curve without incisures and a double peak in SR curve (systolic peak and single diastole peak). The strain in anterior septum and posterior septum, the systolic SRs and diastolic SRs decreased from basal to apical segments. However, only the strain in basal segment and that in apical segment in anterior septum showed statistic difference (t=1.79, P<0.05);the systolic SRs of the same level in different walls and those in the same wall at different levels had no statistic difference (P>0.05). Conclusion Most normal infants and young children present a smooth diastolic strain curve and a double peak SR curve of LV, which can provide clinical guidance in the early diagnosis of myocardial abnormality for infants and young children.

CD4 count is the standard method for determining eligibility for highly active antiretroviral therapy (HAART) and monitoring HIV/AIDS disease progression, but it is not widely available in resource-limited settings. This study examined the correlation between total lymphocyte count (TLC) and CD4 count of HIV-infected patients before and after HAART, and assessed the thresholds of TLC for making decisions about the initiation and for monitoring HAART. A retrospective study was performed, and 665 HIV-infected patients with TLC and CD4 count from four counties (Shangcai, Queshan, Shenqiu and Weishi) were included in the study. Pearson correlation and receiver operating characteristic (ROC) were used. TLC and CD4 count after HAART was significantly increased as compared with pre-HAART (P<0.01). An overall positive correlation was noted between TLC and CD4 count (pre-HAART, r=0.73, P=0.0001; follow-up HAART, r=0.56, P=0.0001). The ROC curve between TLC and CD4 count showed that TLC ≤ 1200 cells/mm(3) could predict CD4 < 200 cells/mm(3) with a sensitivity of 71.12%, specificity of 66.35% at pre-HAART. After 12-month HAART, the optimum prediction for CD4 count < 200 cells/mm3 was a TLC ≤ 1300 cells/mm(3), with a sensitivity of 63.27%, and a specificity of 74.84%. Further finding indicated that TLC change was positively correlated to CD4 change (r=0.77, P=0.0001) at the time point of 12-month treatment, and the best prediction point of TLC change for CD4 increasing was 135 cells/mm(3). TLC and its change can be used as a surrogate marker for CD4 count and its change of HIV-infected individuals for making decisions about the initiation and for monitoring HAART in resource-limited settings.
