Objective To explore the effect of endocrine therapy in breast cancer patients whose estrogen receptor (ER) and progesterone receptor(PR) was preoperatively negative and turned positive after neoadjuvant chemotherapy. Methods The clinical experimental study was carried out in 97 cases of breast cancer which were divided into endocrine treatment group and control group. The follow-up time ranged from 15 to 60 months. Results In endocrine treatment group, 3 and 5-year disease-free survival were respectively 74.5% (38/51), 60.7% (31/51), and 3 and 5-year overall survival were respectively 80%(41/51), 74. 5% (38/51). In control group, 3 and 5-year disease-free survival were respectively 54.2% (26/46), 41.7%(20/46), and 3 and 5-year overall survival were 60.9%(28/46),50%(23/46),respectively. The corresponding values were significantly higher in endocrine treatment group than in control group(P＜0.05).Conclusions Remedy endocrine therapy improves the disease-free and overall survival rate in breast cancer patients with the expression of ER and PR turning positive after initial neoadjuvant chemotherapy.

Objective To observe the change ofbrain water content,levels of cAMP response element binding protein(CREB)and phosphorylated CREB(p-CREB) in the early stage of traumatic brain injury(TBI) and to investigate the effect of TBI and p-CREB on learning and memory.Methods Fifty-four male adult Wistar rats were randomized into the normal group(18 cases),control group(18 cases) and TBI group(18) according to the random number table method.The TBI model was built according to the modified Feeney method and previous experimental parameters.At 12 h after TBI,Western blot analysis were performed to measure the expressions of hippocampal tissue CREB and p-CREB,the Morris water maze test was used to detect the behavior of rats in each group and the wet-dry method was applied to test brain water content.Results The brain water content at 12 h after TBI in the TBI group was remarkably risen compared with the normal group and control group;the expression levels of hippocampal CREB and p-CREB at 12 h after TBI in the TBI group were significantly decreased compared with the normal group and control group,the latent stage was increased and the frequency searching the accuracy within 2 min was decreased.Conclusion Brain edema is obvious after TBI and the levels of CREB and p-CREB are decreased,which maybe one of the reasons for the impairment of learning and memory function after TBI.

Objective To explore the related factors and clinical significance of the effect of irrigation on infant with dacryocystitis. Methods A total of 318 eyes of 262 infant were treated with dacryocystitis, and their overall curative effect was observed. Single factor correlation analysis and multivariate Logistic regression were used to analyze 8 factors related to efficacy, such as age of children, length of medical history, severity of symptoms, degree of operation of nurses, degree of parental cooperation, compliance with medication, massage therapy and treatment methods. The effect of each factor on the curative effect. Results It was found that the total effective rate was 90.56 percent of the lacrimal passage in children with 318 tear channel obstruction and dacryocystitis.Single factor analysis results show that the factors influencing the curative effect of single in treatment (χ2= 88.984, P < 0.01), symptom severity (χ2=14.185,P < 0.05) length of history (χ2=18.783, P < 0.05) difference and massage therapy (χ2=10.081, P < 0.05) was statistically significant, the three factors of multiariable Logistic regression analysis results showed that the treatment (P=0.000, OR=0.148,95％ CI 0.052- 0.419) and massage therapy (P=0.012, OR=3.390, 95％ CI 1.309- 8.777) affected infant lacrimal duct flushing out main factors influencing the efficacy of tong. Conclusions The main influencing factors are the different treatment modalities, severity of symptoms the length of medical history and massage therapy in the related factors that affect the effect of infantwith dacryocystitis.

Atherosclerosis (AS) is a chronic and progressive arterial disease. It is an important cause of the occurrence and development of cardiovascular and cerebrovascular diseases. With the development of Traditional Chinese Medicine (TCM), TCM has many advantages in the therapy of AS, with less adverse reactions. Studies have shown that TCM can resist AS, and the mechanism mainly belongs to regulating lipid metabolism, anti-lipid peroxidation, anti-inflammation, anticoagulation, and protecting the structure and function of vascular endothelial cells. The mechanism of TCM for AS is warranted to be studied systematically, and the chemical components need to be further clarified.

ObjectiveTo observe the apoptosis induced by paeoniflorin （PF） in non-small cell lung cancer （NSCLC） cells and explore its mechanism. MethodCell counting kit-8 （CCK-8） was used to detect the inhibition rates of H1299， H292 and A549 cells with different concentrations of PF （2.5， 5， 10， 20， 25 µmol·L^-1）， and to screen suitable concentrations of PF and experimental cells. The inhibitory effect of PF on lung cancer cells was detected by clone formation assay. The effect of PF on cell apoptosis was detected by flow cytometry with annexin V-FITC/propidium iodide （PI） double staining. With the right concentration of drugs， levels of apoptosis-associated protein B-cell lymphoma-2 （Bcl-2）， Bcl-2-associated X protein （Bax）， cleaved Caspase-3 and Caspase-3 were detected by Western blot. At the same time， the molecular expressions of hypoxia inducible factor -1α （HIF-1α） and Hippo signaling pathway were determined. ResultCompared with the blank group， PF significantly inhibited the growth of H1299， H292 and A549 cells of human lung cancer （P<0.01）. PF significantly induced apoptosis in A549 cells （P<0.01）， decreased the Bcl-2/Bax ratio （P<0.01）， and significantly increased the cleaved Caspase-3 expression （P<0.01）. Compared with those in the blank group， the expression levels of HIF-1α， transcriptional coactivator with PDZ-binding motif （TAZ）， large tumor suppressor 1 （LATS1）， Mps one binding 1 （MOB1） and Yes-associated protein （YAP） in A549 cells of the PF treatment group were significantly decreased （P<0.01）， while the expressions of p-LATS1， p-MOB1 and p-YAP were significantly increased （P<0.01）. At the same time， there was no significant effect on the expression levels of phosphorylated mammalian Ste20-like kinase 1 （p-MST1） and MST1， which did not reach a statistical difference. ConclusionAll data demonstrated that PF showed an anti-tumor effect by improving hypoxic conditions and inhibiting the abnormally activated Hippo signaling pathway， thereby inducing and promoting apoptosis in non-small cell lung cancer.
