RESUMEN
Objective:To study the correlation between OPRM1 A118G gene polymorphism (rs1799971) and the dosage of opioid analgesics in patients after lumbar decompression.Methods:From July 2017 to September 2018, 147 patients undergoing selective posterior lumbar decompression under general anesthesia in the People's Hospital of Xinjiang Uygur Autonomous Region were treated with sufentanil intravenous controlled analgesia(PCIA). The gene polymorphism was detected by PCR.The VAS, Ramasy sedation score, total dosage of sufentanil and adverse reactions of sufentanil in 48 h after operation were observed.Results:The genotype frequencies of AA, GA and GG were 30.6%, 55.5% and 13.9%, respectively, the difference was statistically significant(χ 2=6.324, P=0.423), and G and A allele frequencies were 41.7%, 58.3%, respectively, the difference was statistically significant(χ 2=5.559, P=0.184). There were no statistically significant differences in SpO 2, Ramasay sedation score and VAS score among the groups after operation(all P>0.05). The total dosage of sufentanil in OPRM1 mutant GG[(151.0±23.4)μg] and GA[(132.0±19.1)μg] was higher than that in AA[(123.0±16.2)μg] within 48 h of PCIA, the differences were statistically significant( t=5.206, 2.817, all P<0.05). Conclusion:The OPRM1 A118G gene polymorphism(rs1799971) is correlated with the dosage of opioid analgesics after lumbar decompression.
RESUMEN
Objective To evaluate the application values of two kinds of single-platform flow cytometric methods,the Volumetric method based on flow sensor and the Trucount method based on Trucount beads,in the counts of T-lymphocyte subsets in peripheral blood of patients after transplantation.Methods The absolute number and percentage of CD4 +,CD8 +,and CD3 + T cells in peripheral blood samples from 107 patients after liver or renal transplantation were determined by the Trucount method and the Volumetric method,respectively,and their results were compared using paired t-test and linear regression analysis.Five samples with low CD3 + counts were selected and the precisions of the absolute number of CD4 +,CD8 + and CD3 + T ceils detected by the Volumetric method were evaluated.Results There was no significant difference in the levels of CD4+,CD4+/CD3+,CD8+,CD8+/CD3+,and CD4+/CD8 + in peripheral blood between the Trucount method and the Volumetric method (P ＞ 0.05),and the linear regression coefficients between them were from 0.9 to 1.1.When the concentration of CD3 + was equal or more than 40/μL,the coefficients of variation (CVs) were below 5.5％ for the Volumetric method.When the concentration of CD3 + was 20/μL,the CVs of CD3 +,CD4 +,and CD8 + were 5.19％,10.28％ and 6.48％,respectively.Conclusion The single-platform method based on flow sensor is accurate and reproducible for counting T-lymphocyte subsets in peripheral blood,which may be used to monitor the immune state of the patients after liver or renal transplantation.

Objective:To explore the value of combined detection of PCT and IL-6 in differential diagnosis SIRSin ICU patients.Methods:100 patients with ICU admitted to our hospital from 2013 to 2016 were choosen,including 61 cases with non septic SIRS and 39 cases with sepsis,and 50 healthy persons over the same period were selected as control,and they were divided into non-septic group,sepsis group and control group.The levels of serum PCT and IL-6 were detected by electrochemiluminescence assay,and took PCT of 2 g/L and IL-6 of 50 ng/L for the critical value to identify non infectious SIRS and sepsis,to evaluate the clinical diagnostic value of combined detection.Results:The maximum values of PCT and IL-6in the non-septic group respectively were 0.91 ± 0.54 μg/L and 62.77± 11.75 ng/L,in the septic group respectively were 24.49± 5.00 μg/L and 1542.69± 361.66 ng/L,in the control group respectively were 0.08± 0.06 tμg/L and 3.68± 1.11 ng/L,the maximum values of PCT and IL-6 in the non-sepsis group and the sepsis group were significantly higher than control group (P＜0.05).Compared with the non-septic group,the maximum valuesin sepsis group were significantly increased (P＜0.05).The proportions of PCT ＞ 2 g/L and IL-6 ＜ 50ng/L in the non-septic group respectively were 21.31％ and 65.57％,in the septic group respectively were 92.31％ and 87.18％,the proportions of PCT＞2 g/L,IL-6＜50 ng/L in the sepsis groupwere significantly higher chan those in the non-septic group (P＜0.05).The positive predictive values,sensitivity and specificity of PCT were higher than IL-6,the positive value,specificity of combined detection was higher than IL-6 and PCT,while the sensitivity of combined detection was higher than IL-6,P＜0.05.Conclusions:Combined detection of PCT and IL-6 is helpful for differential diagnosis of sepsis and non-septic SIRS.
RESUMEN
OBJECTIVE:To observe the clinical efficacy and safety of Azithromycin combined with Xiaoer xiaoji zhike oral so-lution in the treatment of mycoplasma pneumonia in children. METHODS:Data of 120 children with mycoplasma pneumonia were retrospectively analyzed and divided into observation group (63 cases) and control group (57 cases) by different treatment meth-ods. All children received conventional treatment(reducing fever,relieving cough and resolving phlegm). Based on it,control group received Azithromycin 10 mg/kg,intravenous infusion,once a day,after continuous infusion of 3 d,it stopped 4 d. Observation group additionally received Xiaoer xiaoji zhike oral solution,10 ml for children younger than 5 years old,15 ml for children in 5 years old or over,3 times a day. 1-week was regarded as 1 treatment course,and it lasted for 2-3 courses. Clinical efficacy in 2 group was observed,recovery time of clinical signs,reduction of the number of inflammatory cells before and after treatment were compared,and the incidence of adverse reactions during treatment was recorded. RESULTS:After treatment,the total effective rate in observation group was significantly higher than control group,fever clearance time,disappearance time of cough,rales and pulmonary lesions were significantly shorter than control group,with statistical significance(P0.05). After 1 week treat-ment,the number of eosinophils and CRP level in 2 groups were significantly lower than before,and observation group was signifi-cantly lower than control group,with statistical significance(P0.05). CONCLUSIONS:Azithromycin combined with Xiaoer xiaoji zhike oral solution shows good efficacy in the treatment of mycoplasma pneumonia in children,it can shorten the duration of clinical symptoms,improve the level of in-flammatory cells,and does not increase the incidence of adverse reactions.
RESUMEN
Objective To evaluate the influence of sevoflurane anesthesia on the expression of growth-associated protein 43 (GAP-43) and neural cell adhesion molecule (NCAM) in hippocampal neurons of neonatal rats.Methods Thirty-six pathogen-free Sprague-Dawley rats,aged 7 weeks,weighing 15-20 g,were randomly divided into 4 groups (n =9 each) using a random number table:control group (C group),1.5％ sevoflurane 6 h group (L group),3％ sevoflurane 2 h group (H1 group) and 3％ sevoflurane 6 h group (H2 group).Group L inhaled 1.5％ sevoflurane in oxygen for 6 h.H1 and H2 groups inhaled 3％ sevoflurane in oxygen for 2 and 6 h,respectively.Group C inhaled 30％ oxygcn only.When the neonatal rats were 14 days old,the rats underwent Morris water maze test for 7 consecutive days.Place navigation and spatial probe tests were carried out.After the end of Morris water maze test,the rats were sacrificed,and the hippocampus was obtained for determination of the expression of GAP-43 and NCAM in hippocampal neurons.Results Compared with group C,the escape latency was significantly prolonged,the time of staying at the original platform quadrant was shortened,and the expression of GAP-43 was down-regulated in L,H1 and H2 groups,and the frequency of crossing the original platform was decreased in L and H2 groups.There was no significant difference in NCAM expression among the four groups.Conclusion The mechanism by which sevoflurane anesthesia decreases the cognitive function may be related to down-regulated expression of GAP-43,but not related to NCAM expression in hippocampal neurons of neonatal rats.
