Objective To observe the preemptive analgesia effects of katamine and elonidine, and to find out the influence of preemptive on stress responses. Methods 36 patients with hysteromyoma undergone hysteromyomec-tomy were randomly assigned to three groups (n = 12 each group) :group Ⅰ , control group, without preemptive analge-sia,the patients in control group were given continous epidural analgesia with 2% lidoeaine 12 - 14ml. Group Ⅱ ,the patients were injected 0. 6mg/kg katamine into epidural analgesia 30 minutes before operation. Group Ⅲ,the patients were injected 0. 6mg/kg katamine and 1.5μg/kg clonidine into epidural analgesia 30 minutes before operation. The patients in three groups were recorded VAS score on 2h ,4h ,6h, 12h ,24h after operation, also recorded the change of epinephrine(E) and norepinephrine(NE) and sensation and movement recovery time after operation. The side effects such as dizziness nausea,vomit,and exited talking were observed during the operation. Results The VAS score were significantly different between group Ⅰ ,Ⅱ and Ⅲ. The levels of E and NE in plasma in group Ⅰ were increased more than group Ⅱ and Ⅲ within 24 hours after operation, also there is significant difference in group Ⅱ compared with group Ⅲ in T1 ,T2 ,T3. The time of sensation and movement recovery were remarkably longer in group Ⅲ com-pared with group Ⅰ and Ⅱ, showing significant difference. There were no significant difference in side effects after operation in three groups. Conclusion The preemptive analgesia of kutamine and colnidine can relieve the pain of lower abdominal surgery and stress response after operation,and it do not increase the side effects.

Objective To investigate the characteristics and risk factors of the cerebral artery atherosclerotic stenosis in patients aged 90 years and older. Methods A total of 92 patients,aged 90 years or older,admitted to our hospital from July 2009 to July 2014 were respec-tively enrolled in this study. All participants underwent CTA to assess the presence and severity of atherosclerotic stenosis with intracranial and extracranial cerebral artery. The association between atherosclerotic stenosis and related risk factors were analyzed. Results The preva-lence of cerebral artery atherosclerotic stenosis was high in the cohort. The frequency of stenosis with intracranial artery was higher than the frequency with extracranial artery (86. 2% vs 44. 8%). The most common positions of cerebral artery atherosclerotic stenosis were the middle cerebral artery (43. 1%),the posterior cerebral artery (43. 1%),and extracranial vertebral artery (32. 8%). The mean age,body mass in-dex,systolic and diastolic blood pressure,and fasting blood glucose of stenosis group are significantly different from the non-stenosis group in single factor analysis (P<0. 05). Multivariate Logistic regression analysis showed body mass index was the independent risk factor of cere-bral artery atherosclerotic stenosis(β=1. 326,OR=3. 765,P<0. 05). Conclusion The prevalence of cerebral artery atherosclerotic steno-sis was high in the patients aged 90 years and older. Body mass index was the independent risk factor. The weight control should be pay atten-tion to prevent cerebral artery atherosclerotic stenosis and stroke.

The nucleocapsid protein (N) is a major structural protein of coronaviruses. The N protein of bat SARS-like coronavirus (SL-CoV) has a high similarity with that of SARS-CoV. In this study, the SL-CoV N protein was expressed in Escherichia coli, purified and used as antigen. An Indirect Enzyme-Linked Immunosorbent Assay (indirect ELISA) was developed for detection of SARS- or SL-CoV infections in bat populations. The detection of 573 bat sera with this indirect ELISA demonstrated that SL-CoVs consistently circulate in Rhinilophus species, further supporting the proposal that bats are natural reservoirs of SL-CoVs. This method uses 1-2 μl of serum sample and can be used for preliminary screening of infections by SARS- or SL-CoV with a small amount of serum sample.

This study was to investigate the permeability and absorbability of capsaicin cubosome across abdominal skin of the SD rats in vitro. Diffusion of capsaicin cubosome and cream was performed with the modified Franz diffusion cell technique. The capsaicin cubosome showed no enhancement of skin permeation within 24 hours. However, the deposition amounts of capsaicin in the rat skin in the cubosome group was markedly higher than those in the commercial cream group (P < 0.01). Cubosome showed excellent characetristic of skin-targed which could be a good carrier for the local transdermal drug delivery system.

Objective To discuss Bushen Huoxue Prescription mechanism of action on follicular granulosa cell apoptosis of premature ovarian failure (POF) mice. Methods The mouse zona pellucida 3 as the antigen, multi-point injection of subcutaneous immunization BALB/c to female mice was used to establish autoimmune POF model. Forty clean female mice were randomly divided into blank group, model group, Estradiol Valerate group and Bushen Huoxue Prescription group. All medicine groups were given relevant medicine for gavage, while model and blank groups were given normal saline with the same amount for gavage for 15 days. After the treatment, ovary, uterus, and thymus were weighed, and the viscera index was calculated. An ovarian slice was taken and HE staining was used to observe granulosa cell apoptosis. The levels of E2, LH, and FSH were detected by using the radioimmunoassay method. RT-PCR was used to analyze Fas and Fas-L mRNA expressions in ovarian granulosa cells. Results Compared with blank group, the weight of ovary, thymus, and uterus decreased significantly (P<0.05, P<0.01);Serum E2 level dropped (P<0.01);levels of FSH and LH, and expressions of Fas and Fas-L mRNA increased significantly (P<0.01). Compared with model group, granulosa cell apoptosis significantly decreased, and ovary index, uterus index, and thymus index increased (P<0.05);serum E2 level increased (P<0.01);levels of FSH and LH, and expressions of Fas and Fas-L mRNA significantly decreased (P<0.05). Conclusion Bushen Huoxue Prescription can decrease expressions of Fas and Fas-L mRNA to inhibit cell apoptosis by adjusting the hormone level of hypothalamus-pituitary-ovarianaxis.

Objective: To demonstrate the relevance of heart-type fatty acid binding protein(H-FABP) and brain glycogen phosphorylase isoenzyme type(GPBB) with myocardial injury in sepsis.To explore the effect of H-FABP and GPBB on the severity of disease and clinical prognosis. Methods: A total of 40 cases of children with sepsis were selected in this study from January 1, 2017 to October 31, 2017.According to the illness severity, they were divided into sepsis group(n=15), severe sepsis group(n=13) and septic shock group(n=12), 19 cases of children with non-infectious diseases were selected as the control group for the same period.The levels of serum WBC, C-reactive protein, procalcitonin, cTnI, CK, CK-MB, CK-MB isoenzyme quality and NT-proBNP were collected within 24 hours of admission.The APECHEⅡ scores were calculated for each child.The peripheral blood of the patients within 24 hours after admission was used to determine the levels of serum H-FABP and GPBB by ELISA method.The differences of clinical indicators among the groups were analyzed.According to the survival of patients with sepsis, they were divided into 37 cases in the improved group and 3 cases in the death group.All patients with sepsis were divided into left ventricular ejection fraction(LVEF) normal group(n=26) and LVEF decreased group(n=14). According to whether the serum cTnI was elevated, all children with sepsis were divided into cTnI normal group (n=29) and cTnI increased group (n=11). The differences of H-FABP and GPBB levels were compared.According to the presence or absence of LVEF decline, the area under the ROC curve was used to evaluate the predictive power of each index for myocardial injury in sepsis.Based on the decrease of LVEF, the area under the ROC curve was used to evaluate the prediction of each index for myocardial injury in sepsis. Results: There were significant differences in H-FABP and GPBB levels among the control group, sepsis group, severe sepsis group and the septic shock group (H=42.241, P<0.05; H=32.486, P<0.05). Although there was no significant difference between the improved group and the death group(P>0.05), there was an elevated trend of H-FABP and GPBB in the death group.The levels of H-FABP (t=-3.770, P=0.001) and GPBB (Z=-2.113, P=0.033) were statistically significant in the LVEF normal group and the LVEF decreased group (LVEF≤60%). There were no significant differences in the levels of H-FABP and GPBB between the cTnI normal group and the cTnI increased group (P>0.05), but the cTnI increased group had an increasing trend.The area under the ROC curve in the diagnosis of myocardial injury in sepsis were H-FABP 0.821, NT-ProBNP 0.738, GPBB 0.661, CK 0.560, cTnI 0.512, in which the sensitivity(0.833) and specificity(0.786)of H-FABP were both higher. Conclusion The serum H-FABP and the GPBB levels can be used to monitor for myocardial damage, and it has a correlation with the severity of the disease and the prognosis.H-FABP has a significant advantage over traditional myocardial markers in sensitivity and specificity to determine the myocardial injury of sepsis.
