Objective To study the influence factor of recurrence in breast cancer.Methods The grouping treatment and tumor by stages,tumor transfer were observed in 105 cases with primary breast cancer.Results Among 105 patients,the inside of 2 years relapse was 47.6%(50/105);Tumor Ⅱ period recurrence rate was 40.0%(10/25),Ⅲ period recurrence rate was 28.0%(7/25);Among 105 cases,the distant place transfer to recurrence rate was 31.4%(33/105);Among 105 patients for surgical operation,its relapsing rate was 40.0%,but in 25 cases after operation putting radiation treatment,relapse rate was 16.0%;The part recurrence rate totally was 58.0%(61/105),among them the chest wall recurrence rate was 13.3%(14/105);The supraclavilar lymphonodes transfer was 20.9%(22/105),the axlla lymphnides transfer was 23.8%(25/105);The distant place transfer was 31.4%(33/105).Conclusion The recurrence rate of association treatment obviously is lower than that pure surgical operation,the relapsing of tumor with tumor by stages and transfer relevanted.

Objective To study mRNA expression of neuroglobin (NGB) in thalamus of DAI rats and explore the relation between NGB and heed injury. Method 46 male SD rats were randomly divided into four groups. The DAI model was established according to modi-fied Mamamu method. The mRNA expression of NGB in thalamus at different time point after injury was detected by RT-PCR method. All data were analyzed with statistical software. Result The mRNA expression of NGB in thalamus increased obviously from 30 minutes after in-jury while decreased at the 24th hour after injury. But the expression increased again and reached peak at the 48th hour after injury. Conclu-sion The mRNA expression of NGB in thalamus increased after DM. Those changes suggested NGB might participate in the response mech-anism of stress, secondary ischemia and hypoxic brain injury after neuron injury.

Objective To establish two-dimensional electrophoresis(2-DE) profiles with high resolution and reproducibility in analysis of hypothalamuses in the spontaneous hypertension rats(SHR) with hyperactivity of liver-yang to analyze the difference on the total proteins of hypothalamuses between the SHR and normal rats.Methods The total proteins of hypothalamuses in the rats were separated by immobilized pH gradient-based two-dimensional gel electrophoresis.With coomassie blue staining,the 2-DE image was analyzed by PDQuest 7.0 software.Results The average matching rate of the 2-DE images of hypothalamuses in the two kinds rats was 92% with good reproducibility.Proteins were mainly displayed at range of pI3-8,Mr(14.4～75) kD.The average spots in the SHR with hyperactivity of liver-yang and in the normal rats were 777?27 and 780?31 respectively.There were 22 spots of proteins up-regulated more than two times and 25 spots down-regulated more than two times in the SHR with hyperactivity of liver-yang than those of the normal rats.Conclusion There are 22 spots of proteins up-regulated and 25 spots of proteins down-regulated in the SHR with hyperactivity of liver-yang,which may be involved in the development of hyperactivity of liver-yang.

Objective: To investigate the efficacy and adverse effects of sustained lung inflation (SLI) combined with pulmonary surfactant (PS) in the treatment of neonatal respiratory distress syndrome (NRDS). Methods: This prospective randomized controlled trial included 124 premature infants (gestational age <34 weeks and birth weight <2 000 g) diagnosed with NRDS and in need of PS treatment in Shenzhen Maternity & Child Healthcare Hospital affiliated to Southern Medical University from July 1, 2016 to October 31, 2018. They were randomly divided into experimental or control group, with 62 cases in each. Infants in the experimental group were treated with SLI using T-piece and intratracheal PS, while those in the control group were given PS only. Blood gas analysis and measurement of fraction of inspiration O₂ (FiO₂) and ratio of partial pressure of oxygen (PO₂) over FiO₂ were performed before and 1 h after PS injection. Results of the treatments and incidence of complications were compared. Paired samples t-test, two independent samples t-test, rank-sum test and Chi-square test were used for statistical analysis. Results: There were 56 participants in the experimental group and 54 in the control group who were eventually analyzed. In the experimental group, the pH value, partial pressure of carbon dioxide (PCO₂), FiO₂ and PO₂/FiO₂ at 1 h after PS injection were all improved compared with those before treatment [pH value: 7.26±0.09 vs 7.19±0.09, t=3.814; PCO₂: (51.5±12.6) vs (59.8±16.3) mmHg (1 mmHg=0.133 kPa), t=2.610; FiO₂: 26.0 (21.0-31.5)% vs 40.5 (38.5-51.5)%, U=392.000; PO₂/FiO₂: (284.6±117.9) vs (173.4±59.7) mmHg, t=6.427; all P<0.05]. The overall decrement of FiO₂ after PS injection in the experimental group was more significant than that in the control group [-10.0 (-15.0 to -5.0)% vs -5.0 (-8.0 to 0.0)%, U=706.500, P<0.001]. The experimental group had a higher rate of extubation within 24 h than the control group [80% (45/56) vs 71% (32/54), χ²=5.830, P=0.016]. However, no significant differences were shown in total mechanical ventilation time, non-invasive/high-flow nasal cannula ventilation time, the ratio of re-intubation within 72 h, or the incidence of air leak, bronchopulmonary dysplasia, periventricular-intraventricular hemorrhage, necrotizing enterocolitis or patent ductus arteriosus between the two groups (all P>0.05). Conclusions SLI combined with PS for NRDS babies can increase the rate of extubation within 24 h and promote the down-regulation of FiO₂ without causing significant complications.

Objective To investigate the preventive and adverse effects of postnatal inhalation of Budesonide in early stage on bronchopulmonary dysplasia (BPD) in very low birth weight infants.Methods A total of 105 cases of high risk premature infants with BPD,who were born in the Neonatal Intensive Care Unit (NICU) from Shenzhen Maternity and Child Healthcare Hospital from July 15,2015 to December 25,2016,and their gestational age ≥ 27 weeks and ＜ 32 weeks or birth weight ≥ 1 000 g and ＜ 1 500 g were collected for a prospective randomized controlled trial,and were randomly divided into 3 groups:early inhalation group(34 cases),late inhalation group(34 cases) and non-inhalation group(37 cases).The oxygen time,and the incidence of BPD,periventricular-intraventricular hemorrhage (IVH),retinopathy of prematurity (ROP),necrotizing enterocolitis of the newborns (NEC),patent ductus arteriosus in preterm infants (PDA),sepsis and hyperglycemia of infants in 3 groups were compared.Results The average oxygen time in early inhalation group was 9 days,while in late inhalation group and the non-inhalation group was 15 days and 18 days,respectively.The average oxygen time in early inhalation group was significantly lower than that in the late inhalation group and the non-inhalation group,with the difference being statistically significant (H =6.09,P ＜ 0.05).The noninvasive ventilation time in early inhalation group was 3 days,while both the late inhalation group and non-inhalation group were 6 days.The noninvasive ventilation time in early inhalation group was significantly lower than that in the late inhalation group and non-inhalation group,with the difference being statistically significant (H =6.17,P ＜0.05).The incidence of BPD in the early inhalation group,late inhalation group and non-inhalation group were 14.7％ (5/34 cases),20.6％ (7/34 cases) and 37.8％ (14/37 cases),respectively.The incidence of BPD in non-inhalation group was significantly higher than that in the early inhalation group and late inhalation group,with the difference being statistically significant (x2 =12.017,P ＜ 0.05).There were no significant differences in IVH,ROP,NEC,PDA,sepsis and hyperglycemia among the 3 groups (all P ＞ 0.05).Conclusions Postnatal inhalation of Budesonide in early stage in high risk very low birth weight infants can reduce the incidence of BPD and the oxygen time,and the adverse reactions are not obvious.

Objective To evaluate the value of monitoring non-invasive cardiac output parameters in medical treatment of patent ductus arteriosus (PDA) in premature infants.Method Premature infants with PDA diagnosed three days after birth (gestational age:28 ～ 31 weeks or birth weight of 1 000 ～ 1 799 g) admitted to the neonatal intensive care unit (NICU) of our Hospital from February 2016 to August 2016 were enrolled in the study.These premature infants were assigned into treated PDA group (the treatment group) and untreated PDA group (the observation group) based on results of non-invasive cardiac output parameters CI and MD,with aorta CI ≥2.95 L/(min · m2),MD ≥21.50 m/min and pulmonary artery CI ≥4.55 L/(min · m2),MD ≥26.50 m/min as cut-off values.Statistical analysis was carried out using t test,x2 test.The closure rate of arterial duct of two groups and changes in non-invasive cardiac output parameters before and after the closure of arterial duct in the treatment group were compared.Result The overall closure rate of arterial duct was 85.1％ (57/67).The closure rate of arterial duct of the treatment group was 70.8％ (17/24),that of the observation group was 93.0％ (40/43),and the difference had statistical significance (P ＜ 0.05);Comparing the following parameters before and after ductal closure in the treatment group,the difference of pulmonary artery flow time (FT),aorta stroke volume index (SVI) and the integral of the flow profile (Vti) had statistical significance (P ＜ 0.05) [(217.6±19.3) ms vs.(235.8 ±21.4) ms,(22.4±6.0)ml/m2 vs.(25.2 ±7.7)ml/m2,(15.1 ± 4.1) cm vs.(17.2 ±5.3) cm].In the treatment group,after arterial duct was closed,aorta and pulmonary artery CI,MD decreased to some degree,but the difference had no statistical significance (P ＞ 0.05).Conclusion Non-invasive cardiac output parameters including aorta and pulmonary artery CI,MD have certain guiding significance for PDA drug treatment among premature infants;after PDA drug treatment,arterial duct closure condition cannot be judged simply by the changes of aorta and pulmonary artery CI,MD,ultrasonic cardiogram examination results should also be considered.
