Objective To evaluate the effect of hypothermia on the pharmacokinetics of rocuronium in the pigs with hemorrhagic shock.Methods Thirty-two Bama mini pigs of both sexes,aged 4-6 months,weighing 22-25 kg,were randomly divided into 4 groups (n=8 each) using a random number table:normal temperature control group (group NC),normal temperature+hemorrhagic shock group (group NH),hypothermia control group (group HC),and hypothermia+hemorrhagic shock group (group HH).NC and NH groups were put in the normal temperature environment,and HC and HH groups were put in a freezer at-15 ℃.In NC and HC groups,rocuronium 3.78 mg/kg was injected via the auricular vein after the animals were awake.In NH and HH groups,hemorrhagic shock was then induced by removing 40％ of blood volume from the right femoral artery at a constant speed within 15 min (30 ml/kg),and rocuronium 3.78 mg/kg was injected via the auricular vein at 30 min after the model was successfully established.At 0 (T0),2 (T1),4 (T2),7 (T3),10 (T4),15 (T5),20 (T6),30 (T7),60 (T8),120 (T9),180 (T10),240 (T11) and 300 min (T12) after rocuronium injection,blood samples were collected from the internal jugular vein for determination of the blood concentration of rocuronium by high performance liquid chromatography-tandem mass spectrometry method.The maximum concentration (Cmax),elimination half-life (t1/2),plasma effect-site equilibration rate content (Ke0),area under concentration curve,and mean residence time (MRT) of rocuronium were calculated.Results Compared with group NC,the blood concentration of rocuronium was significantly decreased at T5-T12 in group NH,the blood concentration of rocuronium was significantly increased at T5-T12 in group HC,and t1/2 was significantly prolonged,Ke0 was decreased,and MRT was prolonged in NH and HC groups (P＜0.05 or 0.01).Compared with group HC,the blood concentration of rocuronium was significantly increased at T4-T12,t1/2 was prolonged,Ke0 was decreased,and MRT was prolonged in group HH (P＜0.05).Compared with group NH,the blood concentration of rocuronium was significantly increased at T5-T11,t1/2 was prolonged,Ke0 was decreased,and MRT was prolonged in group HH (P＜ 0.05).Conclusion Hypothermia can reduce the pharmacokinetics of rocuronium in the pigs with hemorrhagic shock.

Microglia are the principal immune effectors in brain and participate in a series ofneurodegenerative diseases. The microglial shapes are highly plastic. The morphology is closely related with their activation status and biological functions. Cerebral ischemia could induce microglial activation, and microglial activation is subjected to precise regulation. Microglia could play either protective or neurotoxic roles in cerebral ischemia. Therefore, regulating the expression of receptors or protein molecules on microglia, inhibiting the excessive activation of microglia and production of pro-inflammatory factors, promoting the release of neuroprotective substances might be beneficial to the treatment of cerebral ischemia. The study about relationship between microglia and cerebral ischemia will shed a light on the treatment of cerebral ischemia. This paper is a review of microglial activation and regulation during cerebral ischemia as well as related therapeutic methods.

OBJECTIVETo observe the protective effect of active fractions of Huanglian Jiedu Decoction (HJD) on primary cortical neuron injury after oxygen-glucose deprivation (OGD)/reperfusion (R) injury. Methods Using macroporous resin method, HJDFE30, HJDFE50, HJDFE75, and HJDFE95 with 30%, 50%, 75%, and 95% alcohol were respectively prepared. Then the content of active components in different HJD fractions was determined with reverse phase high-performance liquid chromatography (RP-HPLC). The OGD/R injury model was induced by sodium dithionite on primary cortical neurons in neonate rats. MTT assay was used to observe the effect of four fractions (HJDFE30, HJDFE50, HJDFE75, and HJDFE95) and seven index components of HJD on the neuron viability.

RESULTSRP-HPLC showed active component(s) contained in HJDFE30 was geniposide; baicalin, palmatine, berberine, and wogonside contained in HJDFE50; baicalin, berberine, baicalein, and wogonin contained in HJDFE75. The neuron viability was decreased after OGD for 20 min and reperfusion for 1 h, (P <0. 01), and significantly increased after administered with HJD, HJDFE30, HJDFE50, and HJDFE75 (P <0. 05, P <0. 01). Geniposide, baicalin, baicalein, palmatine, wogonside, and wogonin could increase the cortical neuron viability (P <0. 05, P <0. 01).

CONCLUSIONSHJDFE30, HJDFE50, and HJDFE75, as active fractions of HJD, had protective effect on primary cortical neuron injury after OGD/R. Furthermore, geniposide, baicalin, and baicalein were main active components of HJD.

Background and purpose:Microsatellite instability (MSI) status is commonly applied to predict the prognosis and chemosensitivity in stage Ⅱ and stage Ⅲ colorectal cancer patients. However, researches of its function on metastasis colorectal cancer are limited. This study investigated its value on prognosis and chemosensitivity in metastatic colorectal cancer (CRC) patients.Methods:We retrospectively investigated tumor tissues from metastasis CRC patients who were treated with oxaliplatin and 5-FU-based therapy regimens (FOLFOX and XELOX). Immunostaining of proteins of the mismatch repair genehMLH1,hMSH2,hMSH6 andhPMS2 was performed. Prognostic value and chemosensitivity in patients with MSI status were also determined.Results:Clinical features from 113 patients were analyzed. No cor-relation of overall survival (OS) and chemosensitivity with MSI status was found. We further investigated 79 patients with synchronous metastasis and palliatively tumor resection. Median progression free survival (PFS) from 22 MSI patients was significant longer than that in 57 MSS patients (19.9 monthsvs 7 months,P=0.005). No significant difference was seen in OS comparison (P=0.07). MSI status was also an independent prognostic factors of PFS by Cox multivariate analysis (MSS/MSI,HR=2.079,P=0.043). Moreover, in this group, MSI patients had improved disease control rate (59.1%vs 31.6%, P=0.025) in chemosensitivity analysis than MSS patients.Conclusion:A better PFS in MSI patients with synchronous metastasis and palliative tumor resection was found after treated with oxaliplatin and 5-FU-based therapy and a better chemosensitivity in MSI patients was also found.
