OBJECTIVETo evaluate the therapeutic effect of compound anisodine (CA) for patients with primary open angle glaucoma (POAG).

METHODSAccording to the modified Hodapp-Parrish-Anderson Visual Fields Grading System, 46 patients with moderate stage POAG were randomized to receive compound anisodine injection (CA group) or venoruton tablets (control group). Visual acuity (VA), IOP, fundus, visual fields (VF) and the blood flow of optic nerve were observed.

RESULTSThe mean of defect (MD) was decreased in CA group after treatment. The PSV and EDV of ophthalmic artery were remarkably improved in both groups, as well as the PSV, EDV and RI of retinal central artery. Compound anisodine was superior in improving hemodynamics of ophthalmic artery and retinal central artery to venoruton.

CONCLUSIONCompound anisodine can protect optic nerve of POAG through improving the visual function and blood supply of optic nerve.

Objective To determine the prevalence and genotype of hepatitis E virus (HEV)among commercial swine population in Eastern and Southern China. Methods Six hundred specimens of swine bile collected from 5 slaughterhouses in Eastern and Southern China from 2007 to 2009 were tested for HEV RNA using nested RT-PCR. PCR products were sequenced for phylogenetic analysis. Results Forty-seven out of the 600 samples (7.83%) were positive for HEV RNA. Based on the 150 nt fragment within HEV ORF2, data from phylogenetic analysis revealed that all the 47 HEV isolates were identified to be genotype Ⅳ, sharing 75.0%-83.4%, 75.0%-84.6%, 71.9%-80.7% and 88.1%-91.5% nucleotide identities with prototype Ⅰ,Ⅱ,Ⅲ and Ⅳ HEV strains respectively while majority of the isolates clustered within their respective isolation sites. Conclusion HEV was widespread in commercial swine population in Eastern and Southern China that raised a serious concern about the safety regarding the consumption of pork products.

Objective To explore the application of parents' presence induction program (PPIP) during anesthesia induction in children in the operation room and the nursing. Methods 86 children patients (1~11 years old) who would accept the operation were randomly divided into the observation and the control group (n=43 in each group). The observation group was accompanied by their parents when the children accepted the anesthesia induction under the instruction of nurses. But the patients were not present in the control group, and the patients were leaded into the operation room directly by the nurses to accept the anesthesia induction. Blood pressure and pulse changes before and after the anesthesia induction of these children patients were observed. The feeling of their heads of family before the operation and the satisfaction about PPIP were investigated. Results Blood pressure and pulses in the control group were significantly higher than those in the observation group before they were leaded into the operation room (P<0.01). 95% of heads of family hoped to accompany their children when they accepted the anesthesia induction, and 93.7% of heads of family wanted to take part in the PPIP. The satisfaction rate about PPIP was 95% after the completion of PPIP. Conclusions There are many profits about PPIP, such as mitigating the fear and anxiety of children and relaxing the unstable feeling of their heads of families before the anesthesia, and reducing the quantity of pre-anesthetic medications. These are helpful to the anesthesia induction and the cooperation of doctor patients. It is a best anesthesia induction mode worthy to be extended in the operation room.

OBJECTIVETo investigate the effect of Jinmaitong (JMT) serum on the proliferation of rat Schwann cells (SCs) primarily cultured in high glucose medium.

METHODSCs were primarily cultured in Dulbecco's minmum essential medium (DMEM control), 50 mmol/L glucose medium (50 mmol/L Glu), 75 mmol/L glucose medium (75 mmol/L Glu), as well as 50 mmol/L glucose medium, with different concentrations of JMT serum (undiluted, 1:2 diluted and 1:8 diluted) and Neurotropin (Ntp), respectively. The proliferation of SCs under different conditions was detected by MTT.

RESULTSCs grew exuberantly in DMEM within 24-72 h, but slowed down at 96 h. The proliferation of SCs was inhibited in 50 mmol/L Glu and 75 mmol/L Glu after cultures of 48, 72 and 96 h, which showed that both were significantly different compared to the control group (P<0.01). The inhibition was more significant in 75 mmol/L Glu than in 50 mmol/L Glu (P<0.05). Spearman's rho analysis revealed that the proliferation of SCs had a negative correlation with the concentration of glucose (r=-0.471, P<0.01). Excluding the time factor, partial correlation showed similar results (r=-0.679, P<0.01). After 48 h, the proliferation of SCs increased significantly in JMT1:2 and Ntp compared with 50 mmol/L Glu (control 0.437+or-0.019, 50 mmol/L Glu 0.367+or-0.035, JMT1:2 0.426+or-0.024, Ntp 0.422+or-0.013; P<0.01), and there were no statistically significant differences among the JMT groups, the Ntp group and the control group (P>0.05).

CONCLUSIONSThe proliferation of SCs was inhibited in high glucose medium, and the inhibition was reduced by different concentrations of JMT serum, especially at JMT1:2.

OBJECTIVETo study the effects of Jinmaitong Capsule (JMT) on the expression of NGF and NGF mRNA in STZ-induced diabetic rats.

METHODFifty SZT-induced diabetic rats were randomly divided into 5 groups including model group, low-dose JMT group (treated with JMT similar to the quintupling dose of adult recommended dosage), middle-dose JMT group (treated with JMT similar to the decuple dose of adult recommended dosage), high-dose JMT group (treated with JMT similar to the twenty-fold dose of adult recommended dosage) and Neurotropin group (treated with Neurotropin similar to the decuple dose of adult recommended dosage). Ten normal rats matching with weight and age served as normal control group. All rats were given intragastric administration for 16 weeks and then killed. Body weight and blood glucose were detected before and at the 4, 8, 12, 16th week after treatment. The hydrothermal tail-flick and pain threshold to mechanical stimulation with Von Frey filament were carried out before death. The expression of NGF and NGF-mRNA in sciatic nerve were detected by SABC immunohistochemical method and real-time fluorogenetic quantitative PCR respectively.

RESULTThe blood glucose levels of STZ-DM rats were much higher than those of normal rats (P < 0.01). In all the treated groups, there were no significant differences among them compared each other or compared with model group. And it got the same result when concerning about body weight no matter how the rats were dealt with. Hydrothermal tail-flick test: The tail-flick latency of STZ-DM rats were much longer than those of normal rats (P < 0.01 or P < 0.05). Compared with model group, the time shortened significantly in low, middle-dose of JMT groups and Neutrophin group. Compared with normal group, the pain thresholds of model group decreased extremely (P < 0.01). Compared with model group, the threshold values of low-dose, middle-dose JMT group and neutrophin group raised strikingly (P < 0.05). The levels of NGF-mRNA expression in STZ-DM rats were much lower than those of the normal rats (P < 0.01). Compared with model group, NGF-mRNA expression of middle-dose JMT group and Neurotropin group upregulated noticeably (P < 0.01). The integrated option density of NGF expression in STZ-DM rats was much lower than the normal (P < 0.01 or P < 0.05). And the levels of NGF in all the treated groups increased notably compared with model group (P < 0.05 or P < 0.01). There were no significant differences among middle-dose JMT group and Neutrophin group.

CONCLUSIONTraditional Chinese medicine JMT could up-regulate the expression of NGF and NGF-mRNA in sciatic nerve.

BACKGROUNDMany researchers suggest that adult mammalian central nervous system (CNS) is incapable of completing self-repair or regeneration. And there are accumulating lines of evidence which suggest that endogenous neural stem cells (NSCs) are activated in many pathological conditions, including stroke in the past decades, which might partly account for rehabilitation afterwards. In this study, we investigated whether there was endogenous neural stem cell activation in intracerebral hemorrhagic (ICH) rat brains.

METHODSAfter ICH induction by stereotactical injection of collagenase type VII into globus pallidus, 5-Bromo-2 Deoxyuridine (BrdU) was administered intraperitoneally to label newborn cells. Immunohistochemical method was used to detect Nestin, a marker for neural stem cells, and BrdU.

RESULTSNestin-positive or BrdU-Labeled cells were predominantly located at 2 sites: basal ganglion around hemotoma, ependyma and nearby subventricular zone (SVZ). No positive cells for the 2 markers were found in the 2 sites of normal control group and sham group, as well as in non-leisioned parenchyma, both hippocampi and olfactory bulbs in the 4 groups. Nestin+ cells presented 4 types of morphology, and BrdU+ nucleus were polymorphologic. Positive cell counting around hemotoma showed that at day 2, Nestin+ cells were seen around hemotoma in model group, the number of which increased at day 4, day 7 (P <0.01), peaked at day 14 (P <0.05), and reduced significantly by day 28 (P <0.01).

CONCLUSIONEndogenous neural stem cells were activated in experimental intracerebral hemorrhagic rat brains.
