Chinese Journal of Biochemical Pharmaceutics 2017;37(4):255-257
Objective To investigate the efficacy of dexmedetomidine in reduce of hyperalgesia in patien with remifentanil anesthesia.Methods 84 patients scheduled for laparoscopic hysterectomy from December 2014 to April 2016 were selected and randomly divided into two groups: the observation group and the control group,42 cases in each group,two groups were intravenous infusion of remifentanil,propofol and inhaled sevoflurane to maintain anesthesia.In the observation group,0.6μg/kg of dexmedetomidine was given 40minutes before the end of the operation(adding to 100mL 0.9%sodium chloride solution,infusion within 10minutes),the control group was given the same volume of 0.9%sodium chloride solution.The visual analogue scale(VAS)and the bruggrmann comfort scale(BCS)were used to evaluate the postoperative pain and comfort of the two groups of patients at different time points,and compare the incidence of adverse events between the two groups.Results The VAS scores of the two groups were significantly different at 1h(T1),4h(T2)and 24h(T3),and the VAS score of the observation group was significant better than that of the control group,the difference was statistically significant(P<0.05),the BCS scores of two group were compared at T1 and T2,the difference was statistically significant(P<0.05),but there was no significant difference between the two groups at T3.The incidence of adverse reactions in the observation group was lower than that in the control group,the difference was statistically significant(P<0.05).Conclusion Dexmedetomidine can relieve and prevent the incidence of hyperalgesia and adverse reactions in patients with remifentanil anesthesia,and improve the analgesic effect of postoperative patients.
2.Diagnosis and prognosis evaluation of 18F-FDG PET/CT in bone marrow infiltration of lymphoma
Journal of International Oncology 2016;43(5):395-397
18 F-fluorodeoxyglucose positron emission tomography/computed tomography (18 F-FDG PET/CT) and bone marrow biopsy (BMB) have high consistency in the detection of lymphoma bone marrow infiltration (BMI).18F-FDG PET/CT has a high sensitivity to Hodgkin lymphoma (HL) and aggressive non-Hodgkin lymphoma (NHL) BMI,while the sensitivity of indolent NHL is low.Since 18F-FDG PET/CT may appears false positive or false negative,so it can not replace the conventional BMB.We can carry out a BMB under the guidance of 18F-FDG PET/CT,which can greatly improve the detection rate of BMI.
3.Changes of plasma level of neuropeptide Y in patients with pregnancy induced hypertension
Chinese Journal of Obstetrics and Gynecology 2001;36(4):206-208
Objective To investigate the changes and its clinical significance of plasma neuropeptide Y(NPY) concentration in patients with pregnancy induced hypertension (PIH). Methods Plasma NPY levels were detected by radioimmunoassay in 30 patients with PIH, 20 normal non-pregnant women and 23 normal pregnant women. The PIH group was subdivided into mild, moderate and Severe subgroups, and the NPY concentration was also measured in these subgroups respectively at admission and one week after delivery. Results The plasma NPY levels in patients with PIH [(164.16±68.32) ng/L] were significantly higher than those of normal non-pregnant women and normal pregnancies [(86.60±20.65) ng/L, (82.42±12.46) ng/L, P<0.01, respectively]. There was significant difference among plasma NPY levels among the patients with mild, moderate, and severe PIH at admission (P<0,01). At one week after delivery the concentrations of plasma NPY were significantly decreased in the moderate and severe subgroups compared with the value measured at admission (P<0.01). Moreover, the NPY levels in patients with severe PIH after delivery were still higher than those of normal non-pregnant women. Conclusions The results suggested that the level of NPY in plasma is increased in women with PIH. Elevated plasma NPY levels may play a key role in the development of PIH.

Objective To study the association of plasma von willebrand factor (vWF) and endothelin-1(ET-1) levels in patients with pregnancy induced hypertension (PIH). Methods Plasma vWF and ET-1 were studied by ELISA method and immunoradiological method respectively in 36 patients with PIH, 18 normal pregnant women and 19 normal non-pregnant women. Results Circulation levels of vWF and ET-1 were increased with increasing severity of the PIH. In mild PIH patients, the levels of plasma vWF [(135.9±30.9)%, (P>0.05)] weren′t significantly higher than those in healthy pregnant women [(131.6±39.2)%,(P>0.05)],but the levels of ET-1 [(63.7±4.8) pg/L] were significantly higher than those in healthy pregnant women [(47.1±4.7) pg/L,(P<0.01)]. There were significant differences between groups of moderate-severe PIH [vWF (174.4±35.4)%, ET-1 (92.6±19.1) pg/L]. There was a positive correlation between the plasma vWF level and ET-1 level. Conclusion The results suggested that plasma vWF and ET-1 concentration could be used as indicators for the severity of PIH.

Objective To evaluate cognitive function of chronic alcoholism patients.Methods The Wechsler Adult Intelligence Scale-Revise in China(WAIS-RC) and WMS-RC,including intelligence quotient,logical Memory.visual memory and stroop test,were investigated and P300 component of auditory event-related potential (ERP,P300),especially the subcomponents P3a and P3b were examined in 100 chronic alcoholism patients,and 70 healthv people matched in age,sex and educational level as controls.Results Compared with controls,the score of Verbal intelligence quotient(VIQ),Performance intelligence quotient (PIQ),Full-scale intelligence quotient (FIQ),logical memory,visual memory (immediate and delayed),and stroop test were significant lower (P <0.05.P<O.01)in chronic alcoholism patients,but the latencies of P3a and P3b wave were significantly prolonged.the amplitude of P3a and P3b wave were significantly decreased in chronic alcoholism patients.Conclusion Chronic alcoholism patients have cognitive function impairment,and P300 is a more sensitive to discover the impairment of the cognitive function.

Objective To study imaging features of neuronal tumors, and to evaluate the value of CT and MRI in diagnosing these tumors. Methods The CT and MRI studies in 10 patients with pathologically proved neuronal tumor were retrospectively reviewed. Results (1) CT showed a mixed attenuation cystic solid mass with calcification in 3 gangliogliomas; The mixed signal intensity on T 1 or T 2WI with heterogeneous contrast enhancement was common in ganglioglioma. (2)Three central neurocytomas had mixed signal intensity. (3)Three dysembryoplastic neuroepithelial tumor (DNT) had decreased signal intensity on T 1 weighted MR images and well demarcated increased signal intensity on T 2 weighted images without peritumoral edema and calcification. Prominent MR imaging features were a gyriform configuration on T 1 or T 2WI. The tumor contrast enhancement was not common; (4)A desmoplastic infantile ganglioglioma (DIG) was located in the frontal and parietal lobes, appearing as cystic tumors with a solid cortical component enhanced intensely. Conclusion Some neuronal tumors possess of specific imaging features, but diagnosis of the tumor with imaging modalities alone may be difficult. Therefore, combined clinical history could help to establish a correct diagnosis.

Purpose:To investigate the expression and significance of CXCR4 in human lung cancer. Methods:Real-time RT-PCR and immunohistochemistry were performed to detect the expression of CXCR4 on 36 lung cancer specimens and 10 normal lung specimens taken from non-cancerous regions adjacent to lung cancer tissue. Results:34 of 36 cases showed positive staining of CXCR4 protein compared with normal lung specimens.CXCR4 expression was independent of pathological type or histological grade. However, in all examined cases, higher expression of CXCR4 tended to be detected in the tumor specimens with lymph node metastasis or regional invasion. Conclusions:Up-regulated expression of CXCR4 was detected in the early stage of lung cancer, and high-level expression of CXCR4 was associated with lung cancer having metastasis.

Objective To investigate the early diagnosis and management of eclampsia complicated with encephalopathy and to reduce the maternal mortality rate. Methods A retrospective study was carried out on 8 cases with encephalopathy caused by eclampsia between Jan. 1988~Dec. 2002. Results There were 8 cases (22.2%) complicated with encephalopathy in 36 eclampsia patients. Four cases presented with cerebral hemorrhage,2 with cerebral infarct,1 with cerebral edema and 1 with hypoxic ischemic encephalopathy. Two women died(25%).
