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.

Objective To investigate the association of the polymorphism of rs3750344 and rs1435252 of G-protein family GABABR2 gene with obesity in population of Uygur and Han. Methods 785 Uygur subjects from Xinjiang and 425 Han subjects from Jinan Maternity and Child Care Hospital were recruited by epidemiology survey. Exposure indicators such as body mass index (BMI), total cholesterol (Tch), triglyceride (TG), fasting glucose (Glu) concentration were measured. Two single nucleotide polymorphisms (SNPs) of rs3750344 and rs1435252 of GABABR2 gene were typed with Taqman. Linkage disequilibrium and haplotype were analysed with Haploview software. Results The frequency of rs1435252 was significantly different in AA carries of Uygur subjects between overweight group (12.5%) and normal weight group (6.6%), the subject with AA genotype significantly increased risk of overweight (OR=1.43, 95% CI: 1.06~1.91). The frequency of rs1435252 was significantly different in A alleles carries of Han subjects between obesity group (80.0%) and normal weight group (65.2%), the subject with A alleles significantly increased risk of obesity (OR=2.13, 95%CI: 1.18~3.86). The C alleles of rs3750344 significantly decreased risk of obesity (OR=0.69, 95%CI: 0.49~0.97) in Uygur, but the significance disappeared after controlling for covariates of age and gender. Conclusion The rs1435252 A allele of GABABR2 gene is a risk factor for overweight or obesity in population of Uygur and Han.

Objective:To evaluate the effect of vacuum disk(VD) for non-invasive treatment of recurrent and acquired pectus excavatum(PE).Methods:From June 2017 to June 2019, 29 patients recruited from our outpatient clinic were included in this retrospective study and followed-up every 3 month according to the schedule. The patients were distributed into three groups(group 1 treated ≤6 months; group 2 treated from 6 months to 12 months; group 3 treated >12 months). The device should be applied regularly for more than 2 hours daily. The deformity chest wall was scanned by three-dimensional(3D)scanner at clinic, and the 3D-depth(3D-DE) and 3D-Haller index(3D-HI) of PE were calculated through Geomagic software.Results:In this cohort, 29 patients were eligible, 18 symmetrical PE and 11 asymmetric PE. The application time ranged from 3 months to 15 months(average 7.6 months). 4 paitents was lifted to a normal level, 23 patients were differently improved. However, 2 paitents had no improvement. The average of the depth and 3D-HI of all patients were improved from 17.7 mm to 11.6 mm and 1.739 to 1.598, respectively. It’s no statistically significant difference for the elevation of 3D-DE and 3D-HI between symmetrical and asymmetric PE( t=-2.821, P=0.558; t=0.074, P=0.068). When comparing the improvement of 3D-DE or 3D-HI of PE to the patient's treatment time, a statistically significant difference was proved between the group 2 and group 1( t=-2.261, P=0.014; t=-0.436, P=0.043), but not between the group 3 and group 2( t=-1.240, P=0.139; t=0.622, P=0.568). The main side effects include moderate subcutaneous hematoma(84%), petechial bleeding(27%), thoracalgia(32%) and chest tightness(17%), no other side effect appear till now. Conclusion:VD for treatment of recurrent and acquired PE is convenient, safe and noninvasive, which can be an alternative treatment for recurrent and acquired PE, However, long term of efficacy evaluation is still needed.

OBJECTIVE: To investigate the effect and mechanism of tea polyphenol (TP) on the proliferation, apoptosis, migration and invasion of nasopharyngeal carcinoma(NPC) cell line HONEl. METHOD: After treated with different concentration of tea polyphenol, CCK-8 assay, fluorescent staining, cell scratching assay and transwell assay were applied to detect the effect of tea polyphenol on the HONE1 cells. Furthermore, the expression of protein VEGF was investigated by flow cytometry assay. RESULT: It was found that tea polyphenol could inhibit NPC cell proliferation significantly in a dose-dependent manner, however, little impact was observed in normal nasopharyngeal epithelial cell line NP69. Furthermore, it was demonstrated by fluorescent staining assay that tea polyphenol could induce NPC cell apoptosis, and cell scratching assay and transwell assay showed that tea polyphenol could inhibit cell migration and invasion. CONCLUSION Tea polyphenol can significantly inhibit cell proliferation, induce cell apoptosis and decreased the migration and invasion ability of NPC cells in vitro. Tea polyphenol might be a tumor suppressor of NPC cells.

Objective To determine the optimal pressure for facemask ventilation during induction of general anesthesia by real-time ultrasonographic measurement of antral cross-sectional area (CSA) in adult patients.Methods Sixty American Society of Anesthesiologists physical status Ⅰ or Ⅱ patients,aged 18-60 yr,with body mass index of 20-25 kg/m2,scheduled for elective operation under general anesthesia,were divided into 5 groups (n=12 each) using a random number table:P10 group,P13 group,P16 group,P19 group and P22 group.After induction of anesthesia,an oropharyngeal airway was inserted,and the patients were ventilated for a 2-min period in a pressure-controlled mode using the two-handed mask ventilation technique.The pressure for facemask ventilation was 10,13,16,19 and 22 cmH2O in P10,P13,P16,P19 and P22 groups,respectively.The antral CSA was measured using real-time ultrasonography before and after facemask ventilation.Respiratory parameters were recorded.Results Compared with group P1O,the number of patients in whom CSA＜340 mm2 after facemask ventilation was significantly decreased in P16,P19 and P22 groups,and the number of patients in whom the tidal volume ≥ 6 ml/kg was increased in P13,P16,P19 and P22 groups (P＜ 0.01).The number of patients in whom optimnal pressure for facemask ventilation was achieved was 2,10,6,4 and 1 in P10,P13,P16,P19 and P22 groups,respectively,with the most cases in group P13 (P ＜ 0.01).Conclusion The optimal pressure is 13 emH2O for facemask ventilation during induction of general anesthesia when determined by realtime ultrasonographic measurement of antral CSA,and it can ensure adequate oxygen supply and reduce gastric insufflation in adult patients.

OBJECTIVETo evaluate the efficacy and safety of testosterone undecanoate (TU) in the treatment of late-onset hypogonadism (LOH) by meta-analysis.

METHODSWe searched Pubmed (until April 1, 2014), Embase (until March 28, 2014), Cochrane Library (until April 17, 2014), CBM (from January 1, 2001 to February 2, 2014), CNKI (from January 1, 2001 to February 2, 2014), Wanfang Database (from January 1, 2000 to February 2, 2014), and VIP Database (from January 1, 2000 to Febru ary 2, 2014) for randomized controlled trials of TU for the treatment of LOH. We evaluated the quality of the identified literature and performed meta-analysis on the included studies using the Rveman5. 2 software.

RESULTSTotally, 14 studies were included after screening, which involved 1 686 cases. Compared with the placebo and blank control groups, TU treatment significantly increased the levels of serum total testosterone (SMD = 6.22, 95% CI 3.99 to 8.45, P < 0.05) and serum free testosterone (SMD = 4.35, 95% CI 1.86 to 6. 85, P < 0.05) but decreased the contents of luteinizing hormone (WMD = -2.23, 95% CI -4.03 to -0.42, P < 0.05), sex hormone binding globulin (WMD = 2.00, 95% CI 1.38 to 2.63, P < 0.05). TU also remarkably reduced the scores of Partial Androgen Deficiency of the Aging Males (WMD = -9.49, 95% CI -12.96 to -6.03, P < 0.05) and Aging Males Symptoms rating scale (WMD = -2.76, 95% CI -4.85 to -0.66, P <0.05) but increased the hemoglobin level (SMD = 2.35, 95% CI 0.29 to 4.41, P < 0.05) and packed-cell volume (SMD = 4.35, 95% CI 1.36 to 7.33, P < 0.05). However, no significant changes were shown in aspertate aminotransferase, alanine transaminase, prostate-specific antigen, or prostate volume after TU treatment (P > 0.05).

CONCLUSIONTU could significantly increase the serum testosterone level and improve the clinical symptoms of LOH patients without inducing serious adverse reactions. However, due to the limited number and relatively low quality of the included studies, the above conclusion could be cautiously applied to clinical practice.
