Objective To compare the characteristics of remifentanil and sufentanil for tracheal intubation general anesthesia in gyneco-logical laparoscopic operation. Methods 80 patients received gynecological laparoscopic operation were randomly divided into the remifen-tanil group and the sufentanil group with 40 patients in each group, and they were performed total intravenous anesthesia with remifentanil or sufentanil respectively. Compare the changes of heart rate, mean arterial pressure in the two groups before and after induction, at the time of intubation, pneumoperitoneum, and after the operation. And differences in two groups were recorded in the recovery time, extubation time, postoperative pain in 24 hours, exhaust time and postoperative complications. Results Change trend and magnitude in heart rate, mean ar-terial pressure had no significant difference in the two groups (P>0. 05). The recovery time, extubation time in remifentanil group was shor-ter (P<0. 01), postoperative pain in 24 hours in sufentanil group was more mild (P<0. 01). Exhaust time and postoperative complications of the two groups had no significant difference (P>0. 05). Conclusion Remifentanil and sufentanil used in gynecological laparoscopic op-eration can achieve good effect. and effects of the two drugs on hemodynamics were similar. Remifentanil can recieve better effect in terms of recovery time, while sufentanil has better postoperative analgesia effect.

Nowadays the pathogenesis of early-onset depression is still uncertain. Only SSRIs are currently approved for clinical use as antidepressants in children and adolescents, indicating that 5-HT is the most important neurotransmitter involved in the dis-ease. Current studies with regard to central 5-HTergic system in early-onset depression mainly focus on 5-HT synthesis deficien-cy, 5-HT transportation dysregulation, as well as the earlier mat-uration of 5-HT system than norepinephrine system. 5-HT precur-sor tryptophan malabsorption and dysregulation of 5-HT synthesis can contribute to 5-HT deficiency. Moreover, the 5-HTTLPR low-expressing genotypes may increase the risk of early-onset de-pression. It is necessary to make preclinical and clinical studies more widely and deeply about the effect of central 5-HTergic sys-tem in early-onset depression in future.

Objective To investigate the gene expression of methyl-CpG-binding protein 2 (MeCP2) and methyl-CpG-binding domain 2 (mbd2) in patients with systemic lupus erythematosus(SLE) and their significance in the pathogenesis of SLE. Methods Semiquantitative reverse transcriptase-PCR was applied to detect the mRNA expression of MeCP2 and mbd2 in PBMCs obtained from relieved (n=17), active (n=17) SLE patients and healthy controls (n=17). The correlations were further analyzed among these parameters. Results No significant difference was observed in the expression level of MeCP2 mRNA among active SLE patients, relieved SLE patients and healthy controls (P>0.05). The expression of mbd2 in relieved SLE patients was significantly higher than that in health controls (t=12.8, P<0.01), but lower than that in active SLE patients (t=20.0, P<0.01). The expression of mbd2 positively correlated with SLEDAI (r=0.737, P=0.0001) of patients with SLE, and a positive correlation was also observed between the expression of mbd2 and MeCP2 in healthy controls (r=0.550, P=0.0222). Conclusions The expression of MeCP2 and mbd2 may be mutually constrained in normal human, but this relationship seems to be disturbed in patients with SLE.

Objective To compare the effect of nursing students acting as social volunteers to participate in gerontological nursing practice teaching with traditional practice teaching mode, and promote the reform of teaching mode in nursing practice. Methods Students of two classes from department of nursing, medical college of Wuhan University of Science and Technology were selected as research objects. In class one nursing students acted as social volunteers to participate in gerontological nursing practice teaching (the experimental group), In class two nursing students took practice in geriatric wards according to traditional practice mode(the control group). The practice effect was compared between two groups. Results The average final grade of the experimental group was 86.50, and 78.51 in the control group. Ridit analysis revealed that, setting class one as the experimental group, R=0.796 8,95% confidence interval was 0.715 1-0.878 4, in the control group, R =0.500 0. The investigation showed that the experimental group and the control group were different in moral elevation aspect, teaching level, capability improving aspect and employment promotion aspect, the difference was significant (P<0.01). Conclusions The mode of nursing students acting as social volunteers to participate in gerontological nursing practice teaching has advantage over traditional practice teaching, and it can gain satisfying teaching effect.

OBJECTIVETo investigate the changes in the levels of monocarboxylate transporter-2 in spinal cord horn in a rat model of chronic inflammatory pain.

METHODSMale SD rats weighting 180 - 220 g were randomly divided into two groups(n = 48): normal saline group (NS group), complete Freund's adjuvant group (CFA group). Rats were given injections of CFA 100 µl in left hind paw in group CFA, and an equal volume of saline was given injection in group NS. Mechanical withdraw threshold(MWT) and thermal withdraw latency(TWL) were measured at before injection(T0 and 3 h, 1 d, 3 d, 7 d, 14 d, and 21 d after injection(T1-7). Four rats were chosen from each group at T0-7 and sacrificed, and L4-5 segments of the spinal cord horn were removed for measurement of the expression of monocarboxylate transporter-2 by Western blot analysis.

RESULTSIn CFA group, mechanical hyperalgesia and allodynia appeared on the 3 h after CFA injection, then until the day 14. The expression of monocarboxylate transporter-2 in the spinal dorsal horn of rats in CFA group was significantly higher than that in normal control group at T1-6(P <0.05). The protein level of monocarboxylate transporter-2 was apparently correlated with MWT and TWL(P <0.01 and P <0.05) in CFA group.

CONCLUSIONThe level of monocarboxylate transporter-2 in spinal dorsal horn is significantly increased in a rat model of chronic inflammatory pain and the change may involve in the formation and maintenance of central sensitization in spinal cord of chronic inflammatory uain.

Objective To investigate the clinical significance of CD14+HLA-G+ monocytes in pe-ripheral blood and the soluble form of HLA-G ( sHLA-G ) in plasma among patients with gastric cancer ( GC) . Methods Blood samples were collected from 135 patients with gastric cancer ( GC group) , 150 pa-tients with chronic gastritis ( CG group) and 80 healthy controls ( HC group) . Flow cytometry analysis and ELISA were used to detect the percentages of CD14+HLA-G+ monocytes in peripheral blood samples, the concentrations of sHLA-G in plasma samples and the levels of alpha fetoprotein (AFP), cacino-embryonic antigen ( CEA) , CA19-9 and CA125 in serum samples. Mann-Whitney U test was performed to analyze the differences between different groups. The feasibility of using CD14+HLA-G+ monocytes, sHLA-G, AFP, CEA, CA19-9 and CA125 as potential biomarkers to differentiate patients with GC from those with CG or healthy subjects was assessed by using receiver operating characteristic ( ROC ) curve analysis. Results The median percentages of CD14+HLA-G+ monocytes in subjects from GC, CG and HC groups were 18. 6% (12. 1%-26. 7%), 7. 3% (4. 2%-11. 0%) and 4. 6% (3. 6%-6. 3%), respectively. The percentages of CD14+HLA-G+monocytes in the peripheral blood of patients with GC were significantly higher than those in patients with CG and healthy subjects (P<0. 001). The concentrations of sHLA-G in plasma samples collected from patients with GC [(100. 6±61. 3) U/ml) were significantly higher than those in pa-tients with CG [(59.5±19. 9) U/ml) and healthy subjects [(45. 8±23. 3) U/ml] (P<0. 001). ROC curve analysis showed that in terms of GC diagnosis, the area under ROC curve ( AUC) , cutoff value, sensi-tivity and specificity for CD14+HLA-G+monocytes and sHLA-G in plasma were 0. 893 and 0. 720, 12% and 85 U/mL, 75. 8% and 50. 5%, 86. 7% and 95. 9% (P<0. 001), respectively, which indicated that CD14+HLA-G+ monocytes and sHLA-G were better than AFP, CEA, CA19-9 and CA125 in differentiating GC from CG and HC. Moreover, the multivariate logistic regression analysis revealed that the CD14+HLA-G+ monocytes, sHLA-G in plasma as well as CA19-9 and CA125 in serum were positively correlated with the risk of GC after excluding the differences caused by age and gender factors. Conclusion The levels of CD14+HLA-G+ monocytes in peripheral blood and sHLA-G in plasma increased dramatically in patients with gastric cancer, which suggested that CD14+HLA-G+monocytes and sHLA-G might be risk factors for GC and could be used as potential biomarkers for the diagnosis of GC.

Objective To investigate the role of TNSALP gene detection in prenatal diagnosis of HPP. Method The clinical data and the results of complete exon sequencing of TNSALP gene in one neonate with low alkaline phosphatase (HPP) were analyzed retrospectively. Peripheral bloods from his family members were collected. The amniotic fluid cell in fetuses at 17 weeks was tested for candidate gene mutations by Sanger sequencing. Results Mainly manifestations in 6-day-old baby were multiple fractures, limb shortening and bending and dyspnea. He died of respiratory failure 9 days after birth. The serum alkaline phosphatase was decreased and serum calcium was decreased slightly; serum phosphorus, serum 25 hydroxyvitamin-D and parathyroid hormone were normal. X-ray showed that the whole body bone was very poorly mineralized, and the long diaphysis was enlarged with shape of a cup at the end and multiple fractures existed. Gene sequencing revealed a complex heterozygous missense mutation in the TNSALP gene, including the heterozygous missense mutation c.542C>T in exon sixth causing 181st amino acids changed from serine to leucine (p.S181L), and tenth exon heterozygous missense mutation in c.1016G>A causing 339th amino acid changed from glycine to glutamic acid (p.G339E). The parental phenotypes were normal. The c.542C>T mutation is inherited from his father and the c.1016G>A mutation is inherited from his mother. These two mutations were not detected in the fetus. Conclusion TNSALP gene analysis can be applied to the diagnosis and prenatal diagnosis of HPP.
