Translational medicine is inevitable in the development of modern medicine, and the uprising concept of translational medicine provides an opportunity for the development of Chinese medicine (CM). Their ideas are well communicated. There are two patterns of researching on CM based on translational medicine: 'literature to bench to bedside' and 'bench to bedside to bench'. CM has her advantages in preventing and treating cardiovascular disease. Effective methods for preventing and treating cardiovascular disease by CM should be further studied based on translational medicine concepts.

ObjectivesTo present the current condition of non-invasive ventilation in newborns in the last ifve years in China, to describe the probable research trends of this ifeld, and to provide the possible research directions in future.Methods Using co-word analysis, the keywords “neonate” and “non-invasive ventilation” were searched in the CNKI database. The search results included 457 articles. Then the relation matrix was built by Excel 2010. Finally the visualized network was drawn by Ucinet 6.3.ResultsNasal continuous positive airway pressure (nCPAP) is primarily for the treatment of neonatal respiratory distress syndrome (NRDS) in China. Meanwhile, nasal intermittent positive pressure ventilation (nIPPV) and bilevel positive airway pressure (BiPAP) are gradually applied in clinic. The application scope of non-invasive ventilation is expanding. Besides the neonatologists, nurses are also paying close attention to non-invasive ventilation.ConclusionsThe visualized network, successfully built by Netdraw, relfects the hot topics and current condition in this ifeld.

Objective To analyze the characteristics of auditory verbal memory impairment in mild Alzheimer's Disease (AD) and Mild Cognitive Impairment (MCI).Methods Auditory verbal memory test was performed in 72 patients with MCI,45 patients with mild AD,and 62 normal controls.Results Significant intergroup differences were found in total former five free recall and learning scores,The MCI subjects( 16.4?5.5,2.6?1.7)performed significantly more poorly than the normal control subjects(NC) (30.2?5.6,3.4?1.9),and mild AD categories (9.8?4.1,2.0?1.2) showed lower results than the MCI subjects(t=2.26,P

The intestinal absorption of berberine (Ber) and its structural modified compound 8-hydroxy dihydroberberine (Hdber) was compared, and their effects on the intestinal absorption of sugar by perfusion experiment were investigated in order to reveal the mechanism of low dose and high activity of Hdber in the treatment of hyperglycemia. The absorption of Hdber and Ber in rat small intestine was measured by in situ perfusion. High performance liquid chromatography (HPLC) was used to determine the concentrations of Hdber and Ber. In situ perfusion method was also used to study the effects of Hdber and Ber on sugar intestinal absorption. Glucose oxidase method and UV spectrophotometry were applied to examine the concentrations of glucose and sucrose in the perfusion fluid. The results showed that the absorption rate of Ber in the small intestine was lower than 10%, but that of Hdber was larger than 70%. Both Hdber and Ber inhibited the absorption of glucose and sucrose at the doses of 10 and 20 μg/mL. However, Hdber presented stronger activity than Ber (P<0.01). It is suggested that Hdber is absorbed easily in rat small intestine and that its inhibitory effect on the absorption of sugar is better than Ber.

Objective To evaluate the effects of curcumin on the expression of phosphorylated extracellular signal-related kinase (p-ERK) and phosphorylated cAMP response element binding protein (p-CREB) in the spinal dorsal horn and dorsal root ganglion (DRG) in type 2 diabetic neuropathic pain (DNP) in rats.Methods Type 2 diabetes mellitus was induced by high-fat and high-sucrose diet and intraperitoneal streptozotocin (STZ) 35mg/kg,and confirmed by fasting blood glucose level≥ 16.7 mmol/L in male Sprague-Dawley rats.Type 2 DNP was confirmed by the mechanical withdrawal threshold (MWT) and thermal withdraw latency (TWL) measured on day 14 after STZ administration ＜ 80％ of the baseline value,and the rats with type 2 DNP were randomly divided into 3 groups (n =27 each):type 2 DNP group (group DNP),curcumin group (group Cur) and solvent control group (group SC).Curcumin and corn oil 100 mg/kg (25 mg/ml) were injected intraperitoneally once a day for 14consecutive days starting from 14 days after administration of streptozocin in Cur and SC groups,respectively.Another 27 normal rats were served as control group (group C) and were fed with common forage.MWT and TWL were measured at 3,7 and 14 days after curcumin injection (T1 3),and the lumbar segment 4-6 of the spinal cord and DRGs were removed at the same time for determination of the expression of p-ERK and p-CREB (by Western blot).Results Compared with group C,MWT was significantly decreased,TWL was shortened,and the expression of p-ERK and p-CREB in spinal dorsal horn and DRGs was up-regulated at T1-3 in DNP and SC groups,and at T1 in Cur group (P ＜ 0.05).Compared with group DNP,MWT was significantly increased,TWL was prolonged,and the expression of p-ERK and p-CREB in spinal dorsal horn and DRGs was down-regulated at T2,3 in Cur group (P ＜0.05).There was no significant difference in the MWT,TWL and expression of p-ERK and p-CREB between DNP and SC groups (P ＞ 0.05).Conclusion Curcumin can attenuate type 2 diabetic DNP by inhibiting up-regulation of the expression of p-ERK and p-CREB in the spinal dorsal horn and DRG in rats.

Objective: To investigate the changes of ambient dose equivalent rate in 99mTcO4- single photon emission computed tomography (SPECT) of the thyroid among patients with hyperthyroidism, so as to provide insights into radiation protection guidance. Methods: Patients with hyperthyroidism who underwent 99mTcO4- SPECT of the thyroid in a tertiary hospital were enrolled. The ambient dose equivalent rate was measured at different time points following 99mTcO4- infection and at sites with different distances from patients' neck, and the effects of time post-injection, distance from patients' neck, 24-hour thyroidal radioiodine uptake and thyroid weight on the ambient dose equivalent rate were examined using a generalized linear mixed model. Results: Totally 100 patients with hyperthyroidism were enrolled, including 24 men and 76 women and with a mean age of (38.5±14.0) years. The generalized linear mixed model was statistically significant (F=6 610.165, P<0.001), and patients' thyroid weight, time post-injection and distance from patients' neck significantly affected the ambient dose equivalent rate (F=57.967, 15 988.574, 11 200.645, all P<0.001), and the ambient dose equivalent rate positively correlated with patients' thyroid weight and negatively correlated with time post-injection and distance from patients' neck. Conclusions The ambient dose equivalent rate is affected by patients' thyroid weight, time post-injection and distance from patients' neck among patients with hyperthyroidism undergoing 99mTcO4- SPECT of the thyroid. Delay in contact with patients or keeping distance from patients may be effective for radiation protection.

To study the protective effect of Danshen Tongluo capsule on rat hearts in the myocardial infarction (MI) model. After being fed with high fat diets for one month, the SD rats were randomly divided into the sham group and the model group according to the left ventricular ejection fraction (EF). The MI model group was duplicated by ligating coronary artery and then divided into five groups: the model group, the positive control group (model + captopril), the small dose group (model + Danshen Tongluo), the medium dose group (model + Danshen Tongluo) and the high dose group (model + Danshen Tongluo). Four weeks later, changes in myocardium ultra-structure were observed by hemodynamics, cardiac ultrasound and electron microscope. The results showed: (1) All doses of Danshen Tongluo capsule could significantly reduce the left ventricular end diastolic pressure (LVEDP) (P <0.01), increase the maximum internal pressure of the left ventricle (+ dp/dtmax), and lower the drop rate of left ventricular pressure (- dp/dtmax), with statistical significances in medium and high dose groups; (2) The B ultrasound results showed increase in EF and left ventricular shortening fraction (FS) in all dose groups of Danshen Tongluo capsule; (3) The medium dose group showed significant decrease in myocardial infarction index (P <0.01) and injured and fractured myofilament and sarcomere of ischemic myocardium in myocardial ultra-structure; All of Danshen Tongluo capsule-treated groups revealed reduction in myocardial injury and myocardial infraction area. The study preliminarily proves that Danshen Tongluo capsule can improve hemodynamic function, and has a protective effect on myocardial ischemia.

OBJECTIVETo observe the anti-tumor recurrent and metastatic efficacy of Ru'ai Shuhou Recipe (RSR) on HER2 positive breast cancer, to evaluate the effects of RSR on the expressions of matrix metalloproteinases (MMPs) and the tissue inhibitor of metalloproteinases (TIMPs) in the recurrence and metastasis of HER2 positive breast cancer, thus revealing its anti-tumor recurrent and metastatic mechanisms.

METHODSSelected were 30-week-old HER2/neu transgenic spontaneous breast cancer mice FVB/neu. The primary tumor resection was carried out. After surgery they were randomly divided into the blank control group, the RSR group, the Herceptin group, and the combination group (RSR + Herceptin group). The treatment lasted for 4 months. The inhibition rate of the recurrent tumor volume and the inhibition rate of the lung metastasis were evaluated. The expressions of matrix metalloproteinase-2 (MMP-2), matrix metalloproteinase-9 (MMP-9), tissue inhibitor of metalloproteinase (TIMP-1), and TIMP-2 in the recurrent tumor tissue were detected using Western blot.

RESULTSBy the end of the treatment the average recurrent tumor volume was 11.11 +/- 8.71 cm3 in the blank control group and 5.56 +/- 5.55 cm3 of the RSR group, showing statistical difference between the two groups (P = 0.037). The average lung metastatic nodule was 16 in the blank control group and 10 in the RSR group. The inhibition rate of lung metastasis was 37. 85% in the RSR group, but with no statistical significance. The expression level of activated MMP-2 in the RSR group was down-regulated when compared with the blank control group, the Herceptin group, and the combination group (P < 0.05). The expression of MMP-9 of the RSR group, the Herceptin group, and the combination group was significantly down-regulated when compared with the blank control group (P < 0.05). The expression of MMP-9 of the RSR group and the combination group was further down-regulated when compared with the Herceptin group (P < 0.05). The expressions of both TIMP-1 and TIMP-2 of the RSR group, the Herceptin group, and the combination group were all up-regulated when compared with the blank control group (P < 0.05). The increased expression of TIMP-1 was more significantly in the RSR group and the combination group when compared with the Herceptin group (P < 0.05). It was higher in the combination group than in the RSR group (P < 0.05).

CONCLUSIONSRSR could inhibit the tumor recurrence of FVB/neu mice. It could reduce the degradation of extracellular matrix and increase the protective effects of extracellular matrix. It might achieve its anti-tumor effect through effecting the invasive and metastatic capabilities of breast tumor cells.
