ABSTRACT
Objective To investigate effect of Salvia miltiorrhiza Ligustrazine on peripheral lymphocyte neutrophil proportion, neurological function score and prognosis in patients with acute cerebral infarction. Methods 125 cases of acute cerebral infarction in our hospital from June 2015 to June 2016 were selected as the research object, randomly divided into two groups, the control group was treated with conventional treatment of acute cerebral infarction, patients in the observation group in the control group patients on the basis of Salviae Miltiorrhizae and Ligustrazine Hydrochloride Injection, all patients were detected in the blood leukocyte classification, and the NIHSS evaluation of patients with neurological function and prognosis of the two groups of patients. Results After treatment, the observation group of white blood cells in patients with (×109/L), neutrophil (%), neutrophil / lymphocyte was significantly lower than the control group patients, two groups of patients before treatment, after treatment of 1 day and 7 days, two groups of NIHSS score comparison showed no significant difference, after the treatment of 14d patients in the observation group the NIHSS score was (11.1±3.3), which was obviously lower than the control group, the patients in the observation group were six cases death and disability in three cases, 53 cases of independent life, significantly better than the control group, the difference was statistical significance(P<0.05). Conclusion Salvia miltiorrhiza Ligustrazine can help to reduce the ratio of neutrophil / lymphocyte, improve neurological function and improve the prognosis of patients with acute cerebral infarction, and it is worthy of clinical application.
ABSTRACT
Objective To evaluate the measurement uncertainty of the detecting procedure of amino acids and carnitines by the Waters ACQUITY TQD tandem mass spectrometer and PerkinElmer NeoBaseTM non‐derivatized MSMS kit ,and to discuss the meaning of evaluation .Methods According to the method provided by the Medical Laboratories‐Evaluation and Expression of Measurement Uncertainty ,the internal quality control was detected by using two different batch codes of kit for 20 d ,once before and after the routine sample detection on each working day ,the detector were randomly changed ,and then the measurement uncer‐tainty introduced by measurement reproducibility was calculated;the amino acid external assessment quality control data in 20 times of neonatal hereditary metabolic disease tandem mass spectrometry screening provided by the National Center for Clinical Laborato‐ry in 2014 and 2015 ,and the same and 16 times of carnitines external assessment quality control data were performed the statistics , and then the measurement uncertainty introduced by bias was calculated .Next the relative standard uncertainty and the relative ex‐panded uncertainty according to the measurement uncertainty introduced by bias and measurement reproducibility were calculated . The allowed total error indicators of amino acid and carnitines external quality assessment in the neonatal hereditary metabolic dis‐ease tandem mass spectrometry screening by the National Center for Clinical Laboratory were used as the target expanded uncer‐tainty .Results The relative expanded uncertainties of citrulline ,methionine ,phenylalanine ,propionyl carnitine ,octanoyl carnitine , dodecanoyl carnitine ,palmitoyl carnitine and octadecanoyl carnitine were 19 .1% -26 .1% (k=2) ,which were smaller than the tar‐get uncertainty .The relative expanded uncertainties of leucine ,tyrosine ,valine ,free carnitine were 31 .0% -43 .3% (k=2) ,which were greater than the target uncertainty .The uncertainty of isovaleryl carnitine needed to be estimated separately .Conclusion As‐sessing the measurement uncertainty of the detecting procedure of amino acids and carnitines by the non‐derivatized tandem mass spectrometer method can not only provide an opportunity for continuously improving the detection quality ,but also can help the ex‐perimental technique staffs to interpret the test data correctly and the clinician to use the detection reports correctly .
ABSTRACT
BACKGROUND:Severe pain after total hip arthroplasty is an important factor for successful rehabilitation of postoperative joint function. Analgesic method after total hip arthroplasty is a hot issue. OBJECTIVE:To investigate the analgesic effect of different concentrations of ropivacaine after total hip arthroplasty. METHODS:69 patients undergoing total hip arthroplasty were recruited from Department of Anesthesiology, Suqian People’s Hospital, from January 2012 to June 2014. According to the ASA classification, their physical status was graded I to III. The involved patients were randomly divided into three groups:0.25%ropivacaine group, 0.3%ropivacaine group, 0.35%ropivacaine group. Each group had 23 cases. At 30 minutes after the surgery, different concentrations of ropivacaine, 20 mL, were injected to patients due to continuous fascia iliaca compartment block. The catheter was then connected to a patient-control ed analgesia pump programmed to deliver 10 mL with a lockout interval of 60 minutes, for postoperative analgesia (72 hours). At 12, 24, 48 and 72 hours of blockade, the visual analogous scale (VAS) scores at rest, passive and active activity were recorded. When VAS score at rest ≥ 4 points, parecoxib sodium 40 mg was injected intravenously. The consumption of ropivacaine within 72 hours after the blockade, application of parecoxib sodium, time of ambulation, and adverse reactions during blockade were recorded. The analgesic effect in the three groups was also observed. RESULTS AND CONCLUSION:Compared with 0.25%ropivacaine group, static VAS scores of 0.3%ropivacaine group and 0.35%ropivacaine group showed no significant difference (P>0.05), passive and active VAS scores were significantly decreased (P0.05). The ropivacaine consumption of 0.3%ropivacaine group and 0.35%ropivacaine group was not statistical y significant (P>0.05). The usage of parecoxib sodium in 0.3%ropivacaine group and 0.35%ropivacaine group was significantly lower than that in 0.25%ropivacaine group (P0.05). Experimental findings indicate that, three different concentrations of ropivacaine has certain analgesic effects after total hip arthroplasty with fewer adverse reactions, and the concentration of 0.3%ropivacaine is the suitable concentration for postoperative analgesia of total hip arthroplasty, it can reduce the amount of parecoxib sodium and shorten the day of first walk.
