ABSTRACT
Objective To establish the quality standard of Radix Toddaliae Asiaticae. Methods Thin layer chromatography ( TLC) and high performance liquid chromatography ( HPLC) were used to identify and determine chloride nitidine and toddalolactone in Radix Toddaliae Asiaticae. The moisture and total ash contents were detected according to the methods recorded in appendix of Chinese Pharmacopeia (2010 edition) . Results Toddalolactone and chloride nitidine were detectable by TLC, the spots were clear and the dissociation was good. The established HPLC method was simple and accurate. The linear ranges of toddalolactone and chloride nitidine in Radix Toddaliae Asiaticae were 2.84~42.6 μg/mL and 25.6~385 μg/mL, and their recovery rates were 99.2 % ( RSD=1.12%) and 100 % ( RSD=0.71%) , respectively. The content of moisture was in the range of 75.8~98.9 mg/g and that of total ash was in the range of 12.4~33.6 mg/g. Conclusion The developed method is specific and accurate, and can provide useful reference for establishing quality standard of Radix Toddaliae Asiaticae.
ABSTRACT
Objective Clinical effect analysis of low dose dopamine(LDD)and dobutamine (DOB)subsidiary in the treatment of 86 cases of Children serious pneumonia.Methods From July 2011 to July 2013,86 CSP patients who were diagnosed with CSP in People's Hospital of Wenzhou were selected.Patientas were randomly divided into observation group(n=43)and control group(n=43)according to the random number method.Both groups were treated with routine treatment,then observation group on the basis with LDD and DOB subsidiary,then compared efficacy of two groups at 1 week after treatment,as well as the time of symptoms and signs which had improvements,and changes of levels of Interleukin-6(IL-6),Interleukin-8(IL-8), C-reactive protein(CRP)and Tumor necrosis factor-α(TNF-α)before and after treatment. Results The efficacy in observation group was significantly better than that of control group(P<0.05 ).And time of symptoms and signs which had improvement in the observation group was significantly less than control group(P<0.05).After treatment,IL-6,IL-8,CRP and TNF-αlevels were lower than before,but the observation group had a greater degree of reducing(P<0.05).Conclusion Routine treatment combined with LDD and DOB for CSP patients,can significantly improve the therapeutic effect,and relieve the clinical symptoms.
ABSTRACT
Objective:To explore whether perioperative intravenous flurbiprofen axetil can reduce the incidence and intensity of chronic pain for breast cancer atfer surgical treatment. Methods:This randomized, double-blind, controlled trial enrolled 60 patients undergoing mastectomy and axillary lymph node dissection under general anesthesia. All patients accepted Hospital Anxiety and Depression Scale (HAD) tests the day before the surgery to evaluate depression and anxiety. hTe patients were randomly assigned to receive either 50 mg lfurbiprofen axetil intravenously 15 minutes before the surgical incision and 6 hours later (group F) or intravenous 5 mL intralipid as a control (group C). All patients received patient-controlled intravenous analgesia (PCIA) with fentanyl postoperatively. Peripheral venous blood samples were drawn before the surgery, at 4 and 24 h atfer the surgery to detect the plasma level of PGE2 and tumor necrosis factor-α(TNF-α). Postoperative fentanyl consumption, Numerical Rating Scale (NRS) scores and adverse effects were recorded at 2, 6, 12, 24 and 48 h after the surgery. hTe duration and intensity of pain were followed up by telephone at the 2nd-12th month atfer the surgery. Results:The incidence of pain at 2, 4, 6, and 12 months after the breast surgery was 33%, 20%, 15%, and 10%, respectively, and the average pain score was 0.77, 0.57, 0.28, and 0.18, respectively. Compared with group C, the scores of pain in group F were significantly lower at 2, 4, 6 and 12 months postoperatively (F=7.758, P=0.007). The incidence of pain in group F was significantly lower at 2, 4 and 6 months postoperatively (P0.05). Preoperatively and at 4 and 24 h atfer the surgery, there was no signiifcant difference in the level of TNF-αbetween the two groups (F=0.530, P=0.470);but plasma concentration of PGE2 in group F was significantly lower than that in group C (F=5.646, P=0.021). No patients developed abnormal bleeding, peptic ulcer, impaired liver or renal function and respiratory depression. Conclusion:Perioperative intravenous infusion of 100 mg flurbiprofen axetil can decrease the intensity and incidence of chronic pain for breast cancer atfer surgical treatment.
ABSTRACT
Objective To investigate the relevant factors of neonatal ventilator-associated pneumonia(VAP),and to provide a theoretical basis of prevention and treatment.Methods Retrospective analyed the clinical data of 145 critically ill neonates,who were treated with mechanical ventilator from Jan 2006 to Dec 2009 in the Third People′s Hospital of Wenzhou City,NICU.According to whether the neonates were occurred VAP,they were divided into two groups:VAP group(52 cases) and without VAP group(93 cases).Results Fifty-two out of the 145 neonates developed VAP.The incidence of VAP was 35.86%,the main relevent factors were the gestational ages,birth weights,the duration of mechanical ventilation and the times of intubation.There was significant difference between the two groups (P<0.05).The main pathogens were opportunistic bacteria,and mostly were G-bacilli.Conclusion The incidence of VAP has a close conclusion with the gestational ages,the birth weights,the duration of mechanical ventilation and the times of intubation.Regulate the use of breathing machine,strengthen aseptic operation,and select effective antibiotic can control the occurrence and development of VAP.
