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.

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 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.

Objective:To investigate the association between pelvic bone dose-volume parameters and acute bone marrow suppression in cervical cancer treated with concurrent cisplatin and intensity-modulated radiation therapy, in order to provide the limited prescription for making radiotherapeutic plan.Methods:The clinical data of 40 cervical cancer patients receiving cisplatin with concurrent intensity-modulated radiation therapy in the Affiliated Hospital of Ningde Normal College from November 2017 to January 2020 were analyzed. The correlations of the irradiated volume of pelvic bone receiving doses of 5, 10, 15, 20, 25, 30, 35, 40, 45, 50 Gy as a percentage of the total volume of pelvic bone (V 5 Gy,V 10 Gy, V 15 Gy,V 20 Gy,V 25 Gy, V 30 Gy, V 35 Gy, V 40 Gy, V 45 Gy, V 50 Gy), the maximum dose (D max), the minimum dose (D min), and the mean dose (D mean) with the occurrence of ≥grade 3 acute bone marrow suppression were analyzed. The logistic multiple regression analysis was used to study the influencing factors of ≥grade 3 acute bone marrow suppression, and the receiver operating characteristic (ROC) curve was used to determine the diagnostic efficacy of influencing factors for ≥grade 3 acute bone marrow suppression. Results:The incidence rate of ≥grade 3 acute bone marrow suppression was 47.5% (19/40). Between patients with ≥grade 3 and

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 evaluate the prevalence,anatomic features of right superior septal artery (RSSA) with 256-slice MSCT.Methods A retrospective analysis of coronary artery computed tomography angiography with 256-slice CT was performed in 1 646 consecutive patients.Multi-planar reconstruction (MPR),maximum intensity projection (MIP) images on coronal and sagittal planes,and three-dimensional volume rendering (VR) reconstruction images were obtained and used for the evaluation of the anatomic features of the RSSA.The images were transferred to EBW4.52 workstation to trace the vessel and to analyze the origin,diameter,and length of the RSSA.Student's t test was performed to compare the differences in the length and diameter of the RSSA between patients with different coronary artery distribution dominant types,different genders.Analysis of variance (ANOVA) was used to compare the differences in the length and diameter of the RSSA among patients with and without coronary artery stenosis.Results The RSSA was present in 130 (7.9％) of 1 646 patients.The origin of RSSA was from the proximal portion of the right coronary artery in 104 patients,from the right sinus of valsalva in 26 patients.The artery co-existed with the conus artery in 22(16.9％) of 130 patients.The mean length of RSSA was (31.7±15.6) mm (range from 8.9 to 70.7 mm),and the mean diameter was (1.0±0.4) mm (range from 0.2 to 2.5 mm).The average length and diameter of RSSA in men were (33.5±15.7) and (1.0±0.4) mm,respectively; The average length and diameter of RSSA in women were (24.5 ± 13.0) and (0.9 ±0.4) mm,respectively.There was a significant difference in RSSA length between men and women (t=2.718,P=0.007),but there was no significant difference in the RSSA diameter between men and women (t=1.134,P=0.259).There was no significant differencein RSSA length and diameter between different coronary artery distribution dominant types (t=-0.219 and-0.080 respectively,P＞ 0.05).In the patients with left anterior descending artery (LAD) and right coronary artery (RCA) stenosis,the mean length and diameter of RSSA were (38.9±17.9),(1.1 ±0.4) mm,respectively.In the patients without LAD and RCA stenosis,the mean length and diameter of RSSA were (28.9±14.4),(0.9± 0.4) mm,respectively.Patients with coronary artery stenosis tended to have longer RSSAs in comparison to those without coronary artery stenosis (P＜0.05).Conclusions RSSA variantions can evaluated with a cardiac 256-slice MSCT scan.The recognition of this vessel is useful for physians dealing with diagnosis and treatment of coronary artery disease.
