Objective To explore the effect of systemic subhypothermia and erythropoietin combined treatment on neonatal hypoxic-ischemic brain damage(HIBD).Methods Sixty-five asphyxiated newborns enrolled in this study were divided randomly into combination group(n=16),hypothermia group(n=24)and conventional group(n=25).Subhypothermia was adepted in hypotheria group as well as conventional therapy.Subhypotheria and erythropoietin were both applied in combination group excepy for conventional therapy.The short-term effect was evaluated by neonatal neurological score as well as neonatal behavioral neurological assessment(NBNA)on postnatal days of 7,14 and 28,and the long-term effect was evaluated by using intellectual development table made by Children's Development Center of China(CDCC)at 3 and 6 month of age.Results The neonatal neurological score in combination group at 24,48,72 and 80 h were lower than that of 0 and 12 h.NBNA evaluation was much higher on 14 d and 28 d in combination group and hypothermia group than that in conventional group(Pa0.05).Conclusions Combination therapy with systemic subhypothermia and erythropoietin exerts obvious short and longer-time neuroprotective effect on HIBD,but there are no differences compared with hypothermia alone.

Objective:To observe the effect of electroacupuncture (EA) at Jiaji (EX-B 2) points plus hydro-acupuncture with sinomenine hydrochloride for low back pain caused by compression fractures in the elderly.Methods:Ninety-five elderly in-patients with low back pain caused by compression fractures were randomly divided into an observation group and an EA group according to the visit sequence.Both groups received the same basic treatment.In the EA group,48 cases were treated with EA at Jiaji (EX-B 2) points plus the basic therapy;47 cases in the observation group received the basic treatment plus EA and hydro-acupuncture with sinomenine hydroch｜oride at Jiaji (EX-B 2) points.The levels of osteoprotegerin (OPG) and interleukin-1β (IL-1β) in peripheral blood were measured by enzyme-linked immunosorbent assay (ELISA) before and at the 21st day of treatment in both groups.Oswestry disability index (ODI) and visual analog scale (VAS) scores were used to analyze the clinical efficacy.Results:After treatment,the OPG content in the observation group was higher with statistical significance compared with that before treatment in the observation group and after the treatment in the EA group,respectively (both P＜0.05);the content of IL-1β,ODI and VAS scores were lower than those before treatment in the observation group and after treatment in the EA group with statistical significances (all P＜0.05).Conclusion:The combination of EA and hydro-acupuncture with sinomenine hydrochloride at Jiaji (EX-B 2) points is effective for low back pain caused by compression fractures in the elderly,and is superior to EA at Jiaji (EX-B 2) points alone.

Objective To stratify the risks of patients with acute pulmonary embolism (APE) and pulmonary hypertension (PH) by dynamic pulmonary perfusion imaging (DPPI) and pulmonary perfusion imaging (PPI). Methods From October 2007 to February 2009, 20 healthy volunteers ( 12 males, 8 females; mean age =48.47 ±13.47 years) and 31 APE patients (21 males, 10 females; mean age =47.68 ±18.06 years; from October 2007 to July 2009) were included in the study. DPPI and PPI were performed in all subjects. Percentage of perfusion defect scores ( PPDs% ) were calculated by semi-quantitative analysis of PPI. Risk levels were defined according to PPDs% calculated from PPI: normal (PPDs% =0); very low risk (0 ＜ PPDs% ≤10% ); low risk (10% ＜ PPDs% ≤20% ); moderate risk (20% ＜ PPDs% ≤40% );high risk (40% ＜ PPDs% ≤60% ) and very high risk ( PPDs% ＞ 60% ). Lung equilibrium time (LET)was calculated on region of interest (ROI) drawn over DPPI. Clinical risk was scored by Aujesky method.The t-test, ANOVA and correlation analysis were used with SPSS 13.0 software. Results ( 1 ) LET in healthy volunteers and APE patients was ( 12.18 ± 3.28) and (32.90 ± 14.29) s respectively (t = 6. 81,P ＜ 0. 01 ). (2) The correlation coefficient, coefficient of determination between LET and PPDs% in APE patients were 0.93 and 0. 87, respectively. The correlation coefficient between LET and clinical risk score was 0.86. (3)The mean LET of APE patients in very low risk (n =5), low risk (n = 12), moderate risk (n=9), high risk (n=4) and very high risk groups (n=1) were (19.59 ±0.04), (25.03 ±0.08),(36.07 ±0. 10), (57.15 ±0.06) and (70 ±0.00) s, respectively. There was significant difference among APE patients with different risk levels (F =16. 78, P ＜0.01). Conclusions ( 1 ) DPPI was a reliable, convenient and non-invasive method for the evaluation of PH in APE. (2) Combined LET of DPPI and PPDs% of PPI was valuable for risk stratification and prognosis estimation in APE patients.

This paper is aimed to study the effects of nitrogen form on the growth and quality of Chrysanthemums morifolium at the same nitrogen level. In order to provide references for nutrition regulation of Ch. morifolium in field production, pot experiments were carried out in the greenhouse at experimental station of Nanjing Agricultural University. Five proportions of ammonium and nitrate nitrogen were set up and a randomized block design was applied four times repeatedly. The results showed that the growth and quality of Ch. morifolium were significantly influenced by the nitrogen form. The content of chlorophyll and photosynthesis rate were the highest at the NH4(+) -N /NO3(-) -N ratio of 25:75; The activities of NR in different parts of Ch. -morifolium reached the highest at the NH4(+) - N/NO3(-) -N ratio of 0: 100. The contents of nitrate nitrogen in the root and leaves reached the highest at the NH4(+) -N/NO3(-) -N ratio of 50:50. The activities of GS, GOGAT and the content of amylum increased with the ratio of NO3(-) -N decreasing and reached it's maximum at the NH4 + -N/NO3 - -N ratio of 100: 0. The content of ammonium nitrogen were the highest at the NH4 + -N /NO3 --N ratio of 75: 25, while the content of soluble sugar reached the highest at the NH4(+)-N/NO3(-) -N ratio of 25: 75. The content of flavones, chlorogenic acid and 3,5-O-dicoffeoylqunic acid were 57.2 mg x g(-1), 0.673% and 1.838% respectively, reaching the maximum at the NH4(+) -N /NO3(-) -N ratio of 25:75; The content of luteoloside increased with the ratio of NO3(-) -N increasing and reached it's maximum at the NH4(+) -N/NO3(-) -N ratio of 0: 100. The yield of Ch. morifolium reached it's maximum at the NH4(+) -N /NO3(-) -N ratio of 25:75. Nitrogen form has some remarkable influence on the nitrogen metabolism, photosynthesis and growth, Nitrogen form conducive to the growth and quality of Ch. morifolium at the NH4(+) -N /NO3(-) -N ratio of 25: 75.

From original concept and literature of acupoint, the concept and clinical significance of ashi method is discussed, which clarifies that the essence of ashi method is to locate the acupoints by patients' sensitivity on force. The clinical application of heat-sensitive moxibustion has illustrated that positioning method of this therapy is based on the appearance of heat-sensitive moxibustion sensation. Although both types are based on patients' feeling, positioning method of heat-sensitive moxibustion stands on a new angle and uses a new method to locate acupoint. Therefore, it is believed that the positioning method of heat-sensitive moxibustion is the inheritance and development of ashi method.

Objective To investigate the effects of DL-3-n-Butylphthalide(NBP)on proliferation and apoptosis of 1-methyl-4-phenyl-pyridinium (MPP +)-induced SH-SY5Y cells, and mechanisms via mixed lineage kinase 3 (MLK3) signaling pathway. Methods The SH-SY5Y cells were divided into control group,MPP+group,NBP group and URMC-099 group,that cultured normally,with 1 mmol/L MPP+for 24 hours,with 10μmol/L NBP for 3 hours and then with MPP+for 24 hours,and with 200 nmol/L MLK3 inhibitor URMC-099 for 3 hours and then with MPP+for 24 hours,respectively.The morphology of SH-SY5Y cells was observed under inverted phase contrast mi-croscope and the survival rate was measured with 3-(4,5-Cimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide assays.The apoptosis was quantified under flow cytometry with Annexin V/PI fluorescence staining,and the nuclear morphology was observed with Hoechst 33342 staining.The expression of phosphorylated protein of MLK3(p-MLK3),c-Jun N-terminal kinase(p-JNK),extra cellular regulated protein ki-nases(p-ERK1/2)were detected with Western blotting.Results Compared with the control group,the survival rate reduced and apoptosis in-creased in MPP+group(P<0.05),with the increase of p-MLK3 and p-JNK and decrease of p-ERK1/2 d(P<0.05).Compared with MPP+group,the survival rate increased and apoptosis reduced in both NBP and URMC-099 groups(P<0.05),with the decrease of p-MLK3 and p-JNK and increase of p-ERK1/2(P<0.05).Conclusion NBP can decrease the apoptosis and promote the proliferation of SH-SY5Y cells in-duced by MPP+,which may be associated with inhibiting MLK3 signaling pathway,and regulating the downstream p-JNK and p-ERK1/2.

OBJECTIVETo explore the therapeutic effect of interleukin-11 (IL-11) on high-dose methotrexate (HDMTX) induced mucositis in Wistar's rats, the proliferative effect on CEM leukemia cell line and the antitumor effect on HDMTX.

METHODSNinety-five 5-week old, 120 - 150 grams weight Wistar rats were randomly divided into five groups. Group A is normal control (n = 15), group B MTX control (n = 20), group C IL-11 pretreatment group before MTX injection (n = 20), group D (n = 20) the high dose IL-11 group (475 microg.kg(-1).d(-1)) after MTX injection, group E (n = 20) the low dose IL-11 group (150 microg.kg(-1).d(-1)) after MTX injection. All rats in group B approximately E were given 1 ml MTX intraperitoneally (100 mg/kg). Rats were killed at day 1, 3, 5, 7 after MTX injection. The mortality rates, changes of small intestine tissue morphology and ultra structure were observed. The proliferation of small intestine crypt cell was assayed by proliferating cell nuclear antigen (PCNA) immunohistochemical staining. MTT method was used to detect the proliferation of CEM cell line.

RESULTIL-11 treatment resulted in a significant increase of survival of HDMTX treated rats, increased of small intestinal villus length and villus/crypt ratio. IL-11 administration was associated with enhancement of small intestine mucosa recovery after HDMTX therapy. Group C showed a greater effect than group B (P < 0.01). IL-11 had no effect on CEM cell proliferation.

CONCLUSIONIL-11 has a significant mitigating effect on high-dose MTX induced intestinal mucositis in rat, and significantly increase the survival of the rats. IL-11 could be safely used in the HDMTX treatment of childhood acute lymphocyte leukemia.
