Objective To study the effect of preemptive analgesia with tramadol on ovarian cancer patients with stress reaction.Methods 80 cases with ovarian cancer undergoing elective surgery under general anesthesia were divided into the observation group and the control group according to the computer randomly generated control table,40 cases in each group.Patients in the observation group with PECA were pumped into tramadol after anesthesia induction,while the control group was in the same conditions of pumping tramadol after operation.Patients were all treated with intravenous patient -controlled analgesia with sufentanil after waking up.The blood concentrations of cortisol (COR),adrenal cortical hormone (ACTH),angiotensin Ⅱ (AT Ⅱ)were determined by radioimmunoassay, and the blood concentrations C reactive protein (CRP)was determined by immune turbidity method.The adverse reactions and the VAS score of patients after 2h,6h,12h,24h,48h were recorded.Results The COR,ACTH,AT Ⅱ, CRP concentrations of the two groups had no significant differences (all P >0.05)before operation.After each time point,COR[(208.5 ±31.6)ng/mL vs (446.3 ±19.8)ng/mL],ACTH[(35.7 ±8.2)pg/mL vs (63.5 ±9.1)pg/mL],AT Ⅱ[(46.8 ±10.9)pg/mL vs (75.9 ±12.5)pg/mL],CRP[(3.9 ±0.7)mg/mL vs (40.5 ±2.9)mg/mL] concentrations were significantly higher than those of pre -operation (all P <0.05 );The concentration of COR [(446.3 ±19.8)ng/mL vs (570.8 ±67.2)ng/mL],ACTH (63.5 ±9.1)pg/mL vs (85.2 ±12.5)pg/mL),AT Ⅱ[(75.9 ±12.5)pg/mL vs (108.5 ±18.1)pg/mL]and CRP[(40.5 ±2.9)mg/mL vs (51.8 ±8.5)mg/mL]in the observation group was significantly lower than those in the control group (all P <0.05);After operation,the VAS scores of rest (2.4 ±0.7)and cough (3.4 ±1.0)in the observation group were significantly lower than those in the control group in 2h (t =5.812,P =0.017;t =14.606,P =0.044);At rest,the other time point of the two groups of VAS scores had no significant difference (P >0.05);At the time of coughing,the two groups were significantly differ-ent only at the 6h[(2.5 ±0.6)vs (3.1 ±0.8)]and 12h[(2.1 ±0.6)vs (2.9 ±0.4)]time point (t =13.406, P =0.012;t =12.625,P =0.025).Conclusion Preemptive analgesia with tramadol and sufentanil for postoperative analgesia can effectively reduce the radical resection of postoperative pain and the stress reaction after surgery.It is a safe and effective analgesic method.

Objective To test experimentally Fluoro-Jade B(FJB) stain method for detecting degeneration of neurons in the basal ganglia. Methods Kainic acid(KA)-lesion model by stereotaxical injection of KA into striatum of rats,MPTP-lesion model by injection of MPTP into intraperitoneal cavity of mice,as well as KA-lesion model of cultured striatal cells were firstly prepared.FJB stain dye was then used to visualize degeneration of neurons in above KA-or MPTP-lesion models. Results KA-or MPTP-induced degenerative neurons including cell bodies and processes could be clearly visualized by FJB stain dye.In the brain sections,FJB-positive stained degenerative neurons were numerously observed in the striatum of KA-lesion rats and the substantia nigra pars compacta of MPTP-treated mice,but not detected in the control animals.Moreover,degenerative neurons were also detected with FJB stain in cultured striatal neurons.Semi-quantitative analysis on percentage(?s) of FJB-positive neurons constituting total cultured striatal neurons in unit area showed that degenerative neurons of KA-lesion group (8.42?1.09)% was evidently more than that of controls (3.42?0.45)%,P

Objective To study the NR5A1 gene mutation in patients with idiopathic hypogonadotropic hypogonadism(IHH), and to find the new mutation point.Methods Sixty-one IHH patients and 100 normal control subjects were collected and genomic DNA was extracted from blood samples.These patients were with normal karyotype and no abnormality was discovered in magnetic resonance imaging (MRI) scan of the pituitary.Other endocrine diseases were also excluded.The 2-7 exons and splice-sites of NR5A1 gene were amplified with polymerase chain reaction.DNA of the coding sequence and splice-sites of NR5A 1 were sequenced by double deoxidizing terminal end sequencing method in 61 IHH and 100 normal control subjects.The results of sequencing were compared with their corresponding sequence data.61 IHH kindreds were investigated and the clinical data of these patients were collected.Finally, the phenotype and genotype positive cases were analyzed.Results Six patients carried NR5A1 gene mutational sites in 61 cases of IHH.Analysis of sequencing results from 100 age and ethnicity matched control subjects did not show any of these novel changes.Conclusions One mutation in NR5A1 gene may affect protein structure and function, which should be considered in male IHH patients with normal karyotype and without insufficiency of adrenal function.

Objective To elucidate the influences of epitope competition on the frequency and average intensity of specific T cell response.Methods C57BL/6 mice were immunized with either single epitope DNA vaccines (pSV-gag92 or pSV-env203) or fusion gene DNA vaccine (pSV-gag/env).Gag92and Env203 epitope-specific CD8 T cell responses were analyzed by intracellular cytokine staining assay.Results Gag92-specific IFN-γ+CD8 T cells that were induced by pSV-gag92 accounted for 0.415 00％ ±0.045 88％ of the total CD8 T cells,which was much more than that induced by pSV-gag/env of 0.058 67％ + 0.019 64％.Moreover,the mean fluorescence intensity of Gag92-specific TNF-α-IFN-γ+CD8 T cells (296.70+14.08) elicited by pSV-gag/env was significantly lower than that of Env203-specific TNF-α-IFN-γ+CD8 T cells (818.00+49.34).Conclusion Epitope competition could significantly decrease both the frequency and the average intensity of specific T cell response to subdominant epitopes.

Objective To investigate the efficacy and safety of enriched-calorie formula in post-operative infants with congenital heart disease and malnutrition.Methods All malnourished infants less than 6 months diagnosed congenital heart disease: ventricular septal defect and had undergone surgery in Guangzhou Women and Children`s Medical Center from December 1,2014 to May 30,2015 were included in this study.All cases were randomly divided into intervention group(energy-enriched formula,intervention group)and control group(standard formula,control group)for enteral nutrition intervention and observed for 3 months.Body mass,body length,upper arm circumference,blood prealbumin(PA),retinol binding protein(RBP),and B-terminal pro-brain natriuretic peptide(NT-proBNP)were measured before and after ICU,after discharge,and 1 month and 3 months after operation.Results Fifty-one cases were in intervention group and 50 cases in control group,respectively.There were no significant differences in body mass,body length,arm circumference,PA,RBP,mean enteral nutrition starting time,mechanical ventilation time,length of ICU stay,hospitalization time,and average fluid intake between the two groups(all P>0.05).The average caloric intake in intervention group was significantly higher than in control group [(437.24±6.68)kJ vs.(312.43±86.22)kJ,P=0.001].There was no significant difference in NT-proBNP,PA,and RBP at different time points between the two groups(all P>0.05).The improvement of nutrition in intervention group was significantly higher than that in control group at 1 month(25.0％vs.4.9％,P=0.011)and 3 months(64.1％vs.15.7％,P<0.001)after operation.Body mass increased in intervention group [(0.067±0.348)kg] compared with that in control group,and decreased [(0.125±0.425)kg] in control group(P=0.015).Body weight[(5.46±1.36)kg vs.(4.80±1.01)kg,P=0.008],weight for age Z score(WAZ)(-2.79±1.28 vs.-3.75±1.27,P<0.001),and height for weight Z score(WHZ)(-2.47±1.43 vs.-3.62±1.77,P=0.001)one month after surgery were significantly higher than those before operation.Body weight [(6.78±1.42)kg vs.(5.72±1.01)kg,P<0.001] arm circumference [(12.80±1.17)cm vs.(12.00±0.90)cm,P<0.001],WAZ(-1.60±1.17 vs.-3.10±1.40,P<0.001),height for age Z score(HAZ)(-1.41±1.63 vs.-2.10±1.41,P=0.034),and WHZ(-0.86±1.31 vs.-2.59±2.13,P<0.001)of the two groups at 3 months postoperative were significantly higher than those before operation,and the growth rate of intervention group was faster than control group.There were no significant adverse reactions in both groups.Conclusion Calorie-enriched formula powder can help malnourished infants to catch up after congenital heart disease surgery.

Objective To discuss the relationship between cardio-vocal syndrome and pulmonary arterial hypertension in infants with congenital heart disease(CHD).Methods Based on the electronic bronchoscopy results,257 less than one-year-old infants with congenital heart disease were selected and divided into vocal cord paralysis positive group (31 cases) and negative group(226 cases).Factors including age,sex,body weight,pulmonary arterial hypertension degree and PA/AO value were compared between the two groups.The risk factors of left vocal cord paralysis were analyzed using logistic regression method.Results There were no significant differences in age and weight between left vocal cord paralysis positive group and negative group(P ＞0.05).While incidence of pulmonary arterial hypertension and PA/AO value of the positive group were significantly higher than those of the negative group (P ＜ 0.01).The incidence of left vocal cord paralysis in no,mild-moderate and severe pulmonary arterial hypertension groups were 1.39％,10.6％ and 22.0％ (P ＜ 0.05) respectively.Left vocal cord paralysis was positively correlated with the degree of pulmonary arterial hypertension (r =0.179,P ＜ 0.01) and PA/AO value (r =0.169,P ＜ 0.01).Pulmonary arterial hypertension was an independent risk factor of left vocal cord paralysis (P =0.005,OR =1.689).Conclusion Left vocal cord paralysis was significantly correlated with pulmonary arterial hypertension and pulmonary artery dilatation.So pulmonary arterial hypertension should be one of the possible causes of cardio-vocal syndrome in infants with CHD.

Objective: To investigate the changes of ambient dose equivalent rate in 99mTcO4- single photon emission computed tomography (SPECT) of the thyroid among patients with hyperthyroidism, so as to provide insights into radiation protection guidance. Methods: Patients with hyperthyroidism who underwent 99mTcO4- SPECT of the thyroid in a tertiary hospital were enrolled. The ambient dose equivalent rate was measured at different time points following 99mTcO4- infection and at sites with different distances from patients' neck, and the effects of time post-injection, distance from patients' neck, 24-hour thyroidal radioiodine uptake and thyroid weight on the ambient dose equivalent rate were examined using a generalized linear mixed model. Results: Totally 100 patients with hyperthyroidism were enrolled, including 24 men and 76 women and with a mean age of (38.5±14.0) years. The generalized linear mixed model was statistically significant (F=6 610.165, P<0.001), and patients' thyroid weight, time post-injection and distance from patients' neck significantly affected the ambient dose equivalent rate (F=57.967, 15 988.574, 11 200.645, all P<0.001), and the ambient dose equivalent rate positively correlated with patients' thyroid weight and negatively correlated with time post-injection and distance from patients' neck. Conclusions The ambient dose equivalent rate is affected by patients' thyroid weight, time post-injection and distance from patients' neck among patients with hyperthyroidism undergoing 99mTcO4- SPECT of the thyroid. Delay in contact with patients or keeping distance from patients may be effective for radiation protection.

Objective To investigate the role of Wnt/β-catenin pathway in regulating allergic airway inflammation in asthmatic mice.Methods We induced dendritic cells (DCs) from bone marrow of BALB/c mice,and then treated the cells with LiCl and PKF118-310,separately.We observed the morphological features of DCs under light microscope.Mixed lymphocyte reaction (MLR) was used to observe the functional changes of DCs.Western blot was used to detect the expressions of GSK-3β and β-catenin at the protein level.We established a mouse asthma model by using ovalbumin (OVA),and then treated these mice with LiCl and PKF118-310.The total number of cells and eosinophil percentage in BALF were determined.The lungs of mice were observed by HE staining to evaluate the degree of allergic inflammation.The cytokines in BALF and spleen cells supernatant were assayed by enzyme-linked immunoassay (ELISA),and the total IgE in the serum was also measured by ELISA.The protein expression levels of GSK-3β and β-catenin in lung tissue were assayed by Western blot.Results ① The DCs treated with LiCl promoted the proliferation of allogeneic T lymphocytes in MLR more weakly than those treated with PKF118-310 (P＜0.01).② The GSK-3β protein expression level of DCs treated with LiCl was significantly lower than DCs treated with PKF118-310.In contrast,the β-catenin protein expression of DCs treated with LiCl was higher than that of DCs treated with PKF118-310 (P ＜ 0.01).③ The total number of cells and eosinophil percentage in BALF were significantly increased in the experimental group compared with those in the control group (P＜0.01).There was also a significant difference between LiCl group and PKF118-310 group (P＜0.01).④ In the three experimental groups,the severity of inflammation in the lungs of LiCl group was weaker than that in PKF118-310 group (P＜0.05).⑤ Compared with that in the normal control group,IL-4 in BALF and spleen cell culture supernatant of the experimental group was significantly higher while IFN-γ was the opposite (P＜0.01).LiCl group had the lowest level of IL-4 and the highest level of IFN-γ;PKF groups was the opposite (P＜0.05).⑥ The total IgE in serum was significantly increased in the experimental group compared with the control group (P＜0.01).There was also a significant difference between LiCl group and PKF118-310 group (P＜0.05).⑦ GSK-3β protein expression was significantly lower in LiCl group than in PKF118-310 group (P＜0.05),while β-catenin protein expression was significantly higher in LiCl group than in PKF118-310 group (P＜0.05).Conclusion LiCl and PKF118-310 can affect the severity of asthma by regulating Wnt/β-catenin signal pathway and the expressions of GSK-3β andβ-catenin protein,which provides a new direction for asthma treatment.

OBJECTIVETo study the influence of Ureaplasma urealyticum (Uu) infection on the sperm-egg binding associated molecule, sulfogalactosylglycerolipid (SGG).

METHODSEpididymal sperm was collected from adult mice. The sperm suspension was randomly divided into 4 groups: Uu group (coincubated with Uu suspension), medium group (coincubated with Uu medium), normal group and PRS group. The indirect immunofluorescence technique was used to localize SGG on the sperm membrane and to observe the influence of Uu on SGG.

RESULTSIn the epididymal sperm, SGG was localized to the head plasma membrane overlaying the acrosomal region. The SGG-positive rate of the sperm coincubated with Uu medium was 82.0%, while that of the sperm coincubated with Uu suspension was reduced to 39.0% (P = 0.001).

CONCLUSIONUu can adhere to the sperm surface. SGG might be a membrane receptor on the sperm surface for Uu infection of the mammalian male genital tract. The blockage of SGG by Uu might be one of the molecular mechanisms correlative to male infertility induced by Uu infection.
