Objective To investigate the effect of nursing intervention on adverse reactions and quality of life in patients with gynecological cancer received chemotherapy.Methods 160 cases of gynecological cancer patients from 2010 to 2011 in our hospital were chosen as research object.They were randomly divided into the observation group (the nursing intervention group)and the control group (the nonnursing intervention group)with 80 cases in each group.The adverse reactions and quality of life were compared between the two groups.Results The good rate of quality of life for the observation group was 87.5％,higher than that of the control group,and the incidence of adverse reactions was 31.3％,lower than that of the control group,there was significant difference.Conclusions Effective nursing intervention for patients with gynecological cancer chemotherapy can reduce the adverse effects and improve the quality of life for them.It should be widely applied.

Self-ligating brackets have been developed for decades. Now more and more orthodontists are using self-ligating appliance systems, because they have the following advantages over conventional orthodontic brackets: less friction between the archwires and the brackets;simple clinical operation;comfortable for patients. This review introduces the self-ligating brackets' feature, classification and several self-ligating brackets applied in clinic.

Objective To study the effect of preventive treatment of primary dysmenorrhea (belonging to syndrome of stagnation of Qi and blood) by using “acupunctureof regulating Qi and relieving pain”. Methods 60 patientsfrom January 2013 to November 2013(in acupuncture and moxibustion department of Beijing Chinese Medicine Hospital affiliated to Capital Medical University), with Qi and blood stasis type of primary dysmenorrhea were randomly divided into a treatment group (formula of regulating Qi and relieving pain)and a control group(routine acupuncture group), 30 cases in each group. The treatment group was treated with acupuncturing onlieque,fenglong,ligou as the main points while the control group withhegu, diji, sanyinjiao as the main points. All patients received 3 times of acupuncture treatment at the beginning of the week before menstruation and were treated three menstrual cycles altogether. VAS scores, length of pain and CMSSⅡscores during baseline period and three menstrual cycles were observed in order to determine the clinical effects. Results VAS score, length of pain and CMSSⅡscores were significantly reduced than before(P<0.01)[the treatment group in cycle 1 was(5.05±0.98), (14.03±8.37)h, (12.77±3.64), in cycle 2 was (4.18±0.87), (12.53±7.13)h, (12.07±3.69), in cyce 3 was(3.43±0.82), (11.50±6.88)h, (11.33±3.64);the control group in cycle was 1(5.00± 1.05), (14.97±9.19)h、(14.40±3.5), in cycle 2 was(4.25±0.93), (13.83±9.12)h, (13.70±3.43), in cycle 3 was(3.73±0.91), (12.63±9.02)h, (13.03±3.41)];Compared with the control group, VAS scores intreatment groupdecreased more significantly (P<0.05), while reduced level of pain time and CMSSⅡscores showed no significant difference between the two groups (P>0.05). Conclusion Acupuncture of regulating Qi and relieving painmay effectively relieve pain, shortenlength of pain, improve symptoms of dysmenorrhea severity. It has a significant preventive treatment for Qi and blood stasis type of primary dysmenorrhea.

Objective To study the risk factors for failure of INSURE strategy in very and extremely low birth weight preterm (V/ELBW) infants.Method From January 2005 to December 2014,clinical data of 149 preterm infants (gestational age less than 32 weeks) admitted to neonatal department of Tongji Hospital who received intubation-surfactant-extubation (INSURE) strategy were collected.These infants were assigned into two groups:INSURE failure group and INSURE success group,according to whether a second dose of surfactant or mechanical ventilation was needed within 72 hours after first pulmonary surfactant treatment.The clinical characteristics and outcomes between the two groups were compared.Chi square and t tests were used to define the differences between groups.Logistic regression analysis was used to identify the independent risk factors for INSURE failure.Result Among the 1 149 patients,148 received INSURE treatment,and 113 cases (76.4％) were successfully treated with the INSURE strategy.The infants in the failure group were statistically lower in birth weight,gestation age,antenatal steroids utilization rate,PaO2 and PaO2/FiO2 than those in the success group,while the age of mother,male/female ratio and PaCO2 were higher in the failure group.Logistic regression analysis showed that male (OR =7.440,95％ CI 1.846 ～29.984),BW ＜ 1 000 g (OR =9.180,95％ CI 1.716 ～49.105),PaCO2 ＞48 mmHg (OR =5.996,95％ CI 2.088 ～ 17.213),PaO2/FiO2 ＜205 (OR =3.010,95％ CI 1.033 ～8.774) were independent risk factors for INSURE failure.Conclusion INSURE strategy failure was associated with gender,birth weight,gestation age,antenatal steroids utilization,PaO2,PaCO2 and PaO2/FiO2 of the first blood gas after birth.BW ＜ 1 000 g,PaCO2 ＞ 48 mmHg and PaO2/FiO2 ＜ 205 of the first blood gas after birth were independent risk factors for INSURE strategy failure.

A method for determinattion of monoamine neurotransmitters and related compounds in microdialysis solution by high performance liquid chromatography (HPLC) with pulsed amperometric detection was described. A comparison of response of iso potential anperometric (AD) and pulsed amperometric detection (PAD) was made. The results indicated that the sensitivity of PAD was 1.2 fold that of AD. The quantitative determination of monoamine neurotransmitters and related compounds was carried out with 3,4-dihydroxybenzylamine (DHBA) as internal standerd. The recoveries of monoamine neurotransmitters in microdialysis solution are 71% ～ 101%.

Objective To explore the role of brain derived neurotrophic factor(BDNF) promoter methylation for the morbidity of depression patients,and to investigate the relevance between BDNF promoter methylation and the suicidal ideation in patients with first-episode major depressive disorder.Methods The peripheral blood samples from 23 cases of depression patients with suicide ideation ,24 cases of depression patients without suicide ideation,and 27 healthy controls were grouped using simple randomization method, and the methylation status of CpG island of BDNF promoter were subsequently evaluated using bisulphite sequencing.Results The methylation rates(median,quartile interval) of depression patients with suicidal ideation, depression patients without suicidal attempt, and the healthy control were detected as follows, CPG-1 : 2.60 (0.28), 2.70 (0.60), 6.40 (1.00);CPG-2:3.35 (1.15),3.20 (1.00),14.50 (2.60);CPG-3:1.50 (0.40),1.50 (0.60),4.60 (0.90);CPG-4:1.75 (0.90) ,1.50 (0.50),3.90 (0.90);CPG-5:0.80 (0.58),0.90 (1.00),5.70 (2.10);CPG-6:6.05 (1.03),6.20 (1.70), 14.50 (1.70);CPG-7:10.55 (1.68), 10.10 (1.50), 14.70 (1.70);CPG-8:16.35 (0.90), 16.40 (1.00),4.80 (1.20);CPG-9:4.20 (4.80),4.70 (1.30),28.50 (19.30);CPG-10:10.25 (1.08),10.30 (1.20) ,4.30 (0.90);CPG-11:62.80 (4.05) ,62.30 (4.00) ,37.20 (2.60);CPG-12:5.60 (1.05) ,5.60 (1.30) ,12.30 (1.80);CPG-13:4.15 (1.10) ,4.10 (1.10) ,59.70 (4.90);CPG-14:5.45 (0.78) ,5.70 (0.90),6.30 (0.60);CPG-15:3.70 (0.70) ,3.90 (1.00) ,62.40 (6.50);CPG-16:8.05 (1.75) ,8.10 (1.60) ,74.30 (50.90);CPG-17:3.20 (0.78),3.20 (0.80),32.40 (13.20);CPG-18:1.90 (0.48),1.80 (0.40),2.30 (0.30);CPG-19 : 35.00 (6.27), 35.20 (3.00), 64.20 (44.70).There was an obvious difference in methylation rate among three groups,which was statistically significant (P＜0.01).However, no statistical significance for the methylation rates was observed between the depression patients with suicidal ideation and without suicidal ideation.Interestingly, statistical significance for the methylation rates were observed when compared the depression patients with suicidal ideation with healthy control (P＜ 0.05), and the depression patients without suicidal ideation with healthy control (P＜0.05).Conclusion The results show that the association is observed between BDNF promoter methylation and the morbidity of depressive disorder,but not between BDNF promoter methylation and the suicidal ideation of depression patients.

Objective:To investigate the clinical efficacy of different doses of atorvastatin in the treatment of chronic heart failure.Methods:A total of 100 patients with chronic heart failure who received treatment in the Third People's Hospital of Bengbu Medical College from June 2019 to June 2020 were included in this study. They were randomly divided into a control group (conventional treatment + atorvastatin calcium tablet 10 mg, n = 49) and an observation group (conventional treatment + atorvastatin calcium tablet 20 mg, n = 51). Before and after 12 weeks of treatment, serum levels of N-terminal pro-brain natriuretic peptide (NT-proBNP) and inflammatory cytokines such as high-sensitivity C-reactive protein (hs-CRP), interleukin-6 (IL-6), interleukin-10 (IL-10) as well as ventricular remodeling (echocardiographic index) were compared between the two groups. Results:After treatment, serum level of NT-proBNP was (506.56 ± 62.37) pg/mL and (660.85 ± 74.55) pg/mL, serum level of hs-CRP was (14.74 ± 2.69) mg/L and (23.31 ± 3.45) mg/L, serum level of IL-6 was (36.77 ± 4.78) ng/L and (43.12 ± 5.22) ng/L, serum level of IL-10 was (12.36 ± 2.63) ng /L and (15.39 ± 3.56) ng/L, left ventricular end diastolic diameter was (37.74 ± 6.83) mm and (42.36 ± 7.73) mm, left ventricular ejection fraction was (45.78 ± 3.31)% and (42.63 ± 2.56)%, and the ratio of early (E wave) to late (A wave) diastolic velocities (E/A) was (1.44 ± 0.06) and (1.21 ± 0.03), respectively in the observation and control groups. There were significant differences in serum levels of NT-proBNP, hs-CRP, IL-6 and IL-10 as well as LVEDD and LVEF between the observation and control groups ( t = 3.73, 3.07, 3.58, 3.68, 2.99, 3.12 and 2.98, all P < 0.05). Conclusion:Atorvastatin is beneficial to the prognosis of patients with chronic heart failure. The therapeutic efficacy of 20 mg atorvastatin per day is better than that of 10 mg atorvastatin per day.
