Objective To explore the effect of intrauterine growth restriction (IUGR) on the development of brain function in premature infants. Methods A total of 110 premature infants of gestation age of 32-36 weeks were monitored by NicoletOne neonatal cerebral function monitor within 72 hours after birth during January 2015 to February 2016. There were 50 small for gestational age infants (SGA) and 60 appropriate for gestational age infants (AGA). They were continuously monitored for 4-6 hours every time, and the indices of aEEG continuity, sleep wake cycle (SWC), inter-burst interval (IBI), minimum and maximum voltage were compared between two groups. Results The frequency of aEEG continuity, the rate of SWC, and the maximum and minimum voltage in SGA group were all lower than those in AGA group, while the IBI was longer than that in AGA group, and there were significant differences (P<0.05). The frequency of aEEG continuity, the rate of SWC, IBI, and the minimum and maximum voltage were similar (all P> 0.05) among birth weight

AIM: To observe the effect of Retinervus luffae fructus (RLF) on the myocardial ischemia in mice. METHODS: Mice were supplied with RLF (166.7,333.3, 666.7 g/L) twice daily (0.01 mL/g, ig). One week later, 30 U/kg pituitrin was injected intraperitoneally. The electrocardiogram was recorded, and the content of lactose dehydrogenase (LDH) in the serum and the activities of superoxide dismutase (SOD), maleicdialdehyde (MDA) in the myocardium were examined. RESULTS: RLF reduced the height of T wave in electrocardigram in myocardial ischemia mice and inhibited the decrease in heart rate. RLF also reduced the content of LDH in serum and the content of MDA in myocardium. The increase in the activity of SOD in myocardium was also observed. CONCLUSION: RLF may protect myocardium against ischemia injury. The mechanism may be related to the increase in activity of SOD and the suppression of the lipid peroxidation.

OBJECTIVETo study the effect of icariin on vascular endothelial cells (VECs) injury induced by hypoxia.

METHODSThe hypoxia-ischemia model was established. The effect of icariin on injury of VECs activity induced by hypoxia was determined by MTT assay. The levels of malondialdehyde (MDA), superoxide dismutase (SOD) and lactate dehydrogenase (LDH) activity in cell homogenate were measured with corresponding kit. Effect of icariin on cells apoptosis induced by hypoxia was determined by Hoechst 33342 fluorescent staining, cell ultrastructure observation under transmission electron microscopy and analysis on gene fragmentation by flow cytometry and DNA gel electrophoresis.

RESULTSICA could inhibit the hypoxia induced VECs reduction, suppress LDH activity, reduce the MDA production, and enhance SOD activity under hypoxia. Hypoxia could induce VECs apoptosis, revealed chromation condensed in nuclei with the fragments arranged along the nuclear membrane. DNA gel electrophoresis showed typical ladder strands of DNA. Cells displayed a typical sub-diploid peak in flow cytometry. ICA could significantly inhibit the hypoxia induced apoptosis of VECs.

CONCLUSIONICA has the protective effect on hypoxia injured VECs, which may be related to its effect of anti-apoptosis, anti-lipid peroxidation and SOD activity enhancing.

OBJECTIVETo study the effect of electro-acupuncture (EA) at Neiguan (PC6) and Lieque (LU7) on the expression of protein kinases in cardiomyocytes of myocardial ischemia (MI) rats.

METHODSHealthy male SD rats were randomly divided into the control group, the model group, the Neiguan point group, the Lieque point group, and the non-meridian non-acupoint group, 10 in each group by random digit table. The MI rat model was established by injecting isoprenaline hydrochloride (85 mg/kg). EA at Neiguan (PC6), Lieque (LU7), and non-meridian non-acupoint were respectively performed. Changes of the expression of protein kinases [such as protein kinase A (PKA), protein kinase C (PKC), protein kinase G (PKG)] in rat cardiomyocytes were observed using Western blot.

RESULTSCompared with the control group, expression levels of PKA, PKC, and PKG increased obviously in the model group (P < 0.01). Compared with the model group, expression levels of PKA, PKC, and PKG decreased in the Neiguan point group and the Lieque point group (P < 0.01, P < 0.05). Expression levels of PKA decreased in the non-meridian non-acupoint group (P < 0.01). Compared with the Neiguan point group, expression levels of PKA, PKC, and PKG increased in the non-meridian non-acupoint group and the Lieque point group (P < 0.01, P < 0.05). Compared with the Lieque point group, expression levels of PKA, PKC, and PKG increased in the non-meridian non-acupoint group (P < 0.01, P < 0.05).

CONCLUSIONEA at Neiguan (PC6) and Lieque (LU7) could decrease protein expression levels of PKA, PKC and PKG in rat myocardial cells, and the effect of acupuncture at Neiguan (PC6) was better than that obtained by EA at Lieque (LU7).

Serum levels of cuprum, magnesium, iron, ferritin, ceruloplasmin, and lactate dehydrogenase in the onset groups were significantly higher than those in control group ( all P ＜ 0.05 ). On the contrary, calcium, transferrin, total protein, albumin, hemoglobin, and erythrocyte count were significantly lower in the onset groups than those in control group (P ＜ 0.05). Serum iron, cuprum, zinc, and their metabolism were significantly different between acute lymphoblastic leukemia group and acute myeloid leukemia group ( P ＜ 0.05 ).Conclusion　Serum levels of some trace elements and nutritional proteins are disordered and out of balance in chil dren with acute lymphoblastic leukemia and acute myeloid leukemia at stages of onset.

Background and purpose: Docetaxel plus prednisone chemotherapy can improve the patients' survival for castrate-resistant prostate cancer. Angiogenesis inhibitors can also inhibit the growth of tumor. The curative effect of combined treatment is still not clear. This study aimed to evaluate the efficacy of docetaxel plus prednisone combined with thalidomide in treating castrate-resistant prostate cancer (CRPC) patients with bone metastasis. Methods:A total number of 78 CRPC patients were selected in Fuzhou General Hospital from Dec. 2008 to Jun. 2015. Seventy-eight patients were divided into two groups: 40 patients in chemotherapy group (docetaxel plus prednisone) and 38 patients in combined treatment group (docetaxel plus prednisone combined with thalidomide). A total number of 78 subjects were evaluated by the effective rate, the remission rate of bone pain, the prostate specific antigen (PSA) progression-free surviv-al, the overall survival and adverse effect. Results: The response rate (65.79%) and the remission rate of bone pain (86.84%) in combined treatment group were both higher than those in chemotherapy group (40.00% and 60.00%, P<0.05). The PSA progression-free survival (4.13 months), progression-free survival (4.25 months) and the overall survival (18.06 months) in combined treatment group were all longer than those in chemotherapy group (3.54, 3.75 and 16.26 months). The PSA pro-gression-free survival was significantly longer in combined treatment group (P<0.05). There was no significant difference in the overall survival between two groups (P>0.05). The rates of adverse effects including peripheral neuritis and lethargy in combined treatment group (26.32% and 55.26%) were higher than those in chemotherapy group (5.00% and 17.50%, P<0.05). Conclusion: Thalidomide combined with docetaxel plus prednisone in CRPC patients with bone metastasis can prolong the PSA progression-free survival and overall survival. The adverse effects are mild. It may become a new choice of treatment for CRPC.
