Objective To investigate the combination of Oxycodone and Morphine Hydrochloride Injec-tion in cancer pain and breakthrough cancer pain (BtCP).Methods This study included 78 patients with moder-ate or severe cancer pain ,which was titration with Oxycodone and Morphine Hydrochloride Injection .All data were obtained from diagnosed malignant tumors and followed up in the people ′s hospital of Jiangmen city between Jan 2011 and Dec 2015.Results The first 5 days of the titration with a total Morphine Equivalent Dose (MED)be-tween 156~1 491 mg(426.46 ±286.00 mg),and a total dose of IV morphine hydrochloride injection between 2~57 mg(20.96 ±13.25 mg).The mean dose used in the treatment of BtCP was 2.23 ±2.50 mg in Phase B(8 pm~8 am)and 1.96 ±2.14 mg in Phase A(P<0.05).When the treatment begun Numerical Rating Scale (NRS)showed a significant decrease .All the patients were less likely to experience any severe side -effects. Conclusion The titration by Oxycodone and Morphine Hydrochloride Injection is a simple , safe and efficient method,with less side-effect,significantly improve the living quality .It′s a good choice in the titration of moder-ate or severe cancer pain .

OBJECTIVE: To evaluate the effects of madecassoside (MC) on the depression behavior of mice and the activities of monoamine oxidase (MAO) in different rat brain regions. METHODS: Imipramine as the positive contrast medicine, effects of MC on the depression behavior of mice were observed by forced swimming test and reserpine antagonist test. Moclobemide and pargyline as the positive controlled medicines, the activities of monoamine oxidase-A (MAO-A) and monoamine oxidase-B (MAO-B) in different rat brain regions were determined after intragastric administration of MC in 3 different dosages for 3 days or 21 days. RESULTS: (1) The low, middle and high dosages of MC (i.g.) significantly reduced the immobility time of mice in forced swimming test (P<0.05). (2) MC in dosages of 10 mg/kg and 20 mg/kg prevented the lowering of temperature induced by reserpine (P<0.05), while 40 mg/kg had no significant effects on it (P>0.05). (3) With acute administration (3 days), the low, middle and high dosagey of MC (i.g.) significantly inhibited the activity of MAO-A in hippocampus (P<0.01), and the high dosage significantly inhibited the activity of MAO-A in hypothalamus (P<0.01), while the 3 dosages had no significant effects on the activity of MAO-A in cortex (P>0.05). With chronic administration (21 days), MC in 3 dosages had no significant effects on the activities of MAO-A in cortex and hypothalamus (P>0.05), and the high dosage (40 mg/kg) significantly enhanced the activity of MAO-A in hippocampus (P<0.01). (4) With acute administration, MC in dosages of 10 mg/kg and 20 mg/kg significantly inhibited the activity of MAO-B in cortex (P>0.05), and MC in dosage of 10 mg/kg significantly inhibited the activity of MAO-B in hypothalamus (P<0.05), and MC in dosage of 20 mg/kg significantly enhanced the activity of MAO-B in hippocampus (P<0.01). With chronic administration, MC of 3 dosages produced no significant effects on the activities of MAO-B in 3 different rat brain regions (P>0.05). CONCLUSION: These results support the idea that MC produces antidepressant effects through MAO inhibition in rat brain, which seems stronger with acute administration than chronic administration, while its mechanism remains to be further studied.

Objective:To study the relationship among lipoprotein‐associated phospholipase A2 (Lp‐PLA2 ) gene A379V and T403V locus polymorphisms and genetic susceptibility of coronary heart disease (CHD) .Methods:Lp‐PLA2 gene A379V and T403V locus polymorphisms of 160 coronary angiography confirmed CHD patients (CHD group ) and 117 healthy subjects (healthy control group ) were measured using gene sequencing technique .ELISA was used to measure blood lipids and plasma Lp‐PLA2 level in two groups ,and they were compared between two groups . Results:Compared with healthy control group ,there were significant rise in age ,male proportion ,plasma levels of hs‐cTnI ,hsCRP ,TC ,LDL‐C , Lp (a) ,WBC ,mononuclear cells (MNCs) and Lp‐PLA2 [ (119.98 ± 49.41) ng/ml vs .(248.59 ± 76.51) ng/ml] ,and significant reduction in HDL‐C level in CHD group ( P<0.01 all) .The CC , CT , TT genotype and C , T allele were de‐tected all in A379V and T403C locus of two groups .Compared with healthy control group ,there were significant rise in frequencies of CC genotype (1.7% vs .9.3% ) and C allele (13.7% vs .20.3% ) of Lp‐PLA2 gene T403C locus in CHD group , P< 0.05 both . All genotypes and alleles of A379V locus possessed no significant difference between CHD and healthy control group . Conclusion:Plasma Lp‐PLA2 level may be related to CHD risk .Lp‐PLA2 gene T403C locus poly‐morphism possesses certain relationship with genetic susceptibility of CHD .

BACKGROUNDThe purpose of this retrospective study was to compare the surgical outcomes of simple discectomy and instrumented posterior lumbar interbody fusion (iPLIF) in patients with lumbar disc herniation and Modic endplate changes. Our hypothesis was that iPLIF could provide better outcome for patients with refractory lumbar disc herniation and Modic changes (LDH-MC).

METHODSNinety-one patients with single-segment LDH-MC were recruited. All patients experienced low back pain as well as radicular leg pain, and low back pain was more severe than leg pain. Forty-seven patients were treated with discectomy and 44 were treated with iPLIF. The outcomes of both low back pain and radicular leg pain using visual analogue scale (VAS) as well as the clinical outcome related to low back pain using Japanese Orthopaedic Association (JOA) score were assessed before and 18 months after surgery, respectively.

RESULTSBoth low back and leg pain were significantly improved 18 months after simple discectomy and iPLIF. Compared to patients undergoing simple discectomy, low back pain was significantly reduced in patients undergoing iPLIF, but there was no significant difference in leg pain between two groups. Solid fusion was achieved in all patients who underwent iPLIF.

CONCLUSIONSIn patients with LDH-MC, iPLIF can yield significantly superior outcome on the relief of low back pain compared to simple discectomy. Simple discectomy can relieve radicular leg pain as efficient as iPLIF. Accordingly, iPLIF seems to be a reliable treatment for patients with LDH-MC and predominant low back pain.
