The present study aimed to investigate the effect of Glomus versiforme and Trichodema harzianum on the growth and quality of Salvia miltiorrhiza continuous cropping under field conditions. The field plot experiment was conducted, these active components in the plant were analyzed by HPLC, the root diseases incidence rate of S. miltiorrhiza determined by observation and counting, and relative parameters were measured. The data was statistically processed. The result showed that inoculation of G. versiforme and combined inoculation of G. versiforme with T. harzianum significantly decreased the root diseases incidence rate of S. miltiorrhiza, and combined inoculation of G. versiforme with T. harzianum was better than other treatments. All treatments improved accumulation of active ingredients in root. Inoculation of G. versiforme and combined inoculation of G. versiforme with T. harzianum significantly increased the content of salvianolic acid B and cryptotanshinone of root (P < 0.05), Inoculation of G. versiforme, T. harzianum and combined inoculation of G. versiforme with T. harzianum significantly enhanced the content of tanshinone I and tanshinone II(A) of the root (P < 0.05). It may conclude that inoculation of G. versiforme and combined inoculation of G. versiforme with T. harzianum can effectively reduce the root diseases incidence of continuous cropping S. miltiorrhiza, and improve the quality of S. miltiorrhiza.

Background The mechanism of both selenite-induced cataract and age-related cataract is oxidative damage.N-acetylcysteine (NAC) is one of the effective antioxidants,but the literature is little about the preventive and treating effects of NAC on cataract. Objective This study attempted to investigate the preventive and therapeutical effects of NAC on the selenite-induced cataract,and to discuss the possible mechanism. Methods Sixty 10-day-old clean SD rats were randomly divided into normal control group-1,normal control group-2,selenite-induced cataract group,NAC preventive group,NAC+normal saline group and NAC treatment group.Selenite cataract models were induced by subcutaneous injection of 3.46 mg/kg sodium selenite once daily for three days.The rats of NAC preventive group received the intraperitoneal injection of 2 mmol/L NAC 30 minutes before the injection of sodium selenite once daily for 6 days.In NAC treating group,2 mmol/L NAC was intraperitoneally injected 1 day after the injection of sodium selenite for 30 days,and the normal saline solution was injected at the same method in the NAC+normal saline group.Lens opacification was graded according to LOCS Ⅲ criteria.Histopathological change of lens epithelium was examined under a light microscope after hemotoxylin and eosin staining,and the ultrastructure was observed under the scanning electron microscope.The expression of caspase-3 in lens was assayed using immunochemistry.The levels of superoxide dismutase ( SOD ),malonaldehyde ( MDA ) in rat lens were detected respectively in corresponding time points.The use of the experimental animals complied with the Regulation for the Administration of Affairs Concerning Experimental Animals by State Science and Technology Committee. Results In 7 days after experiment,lenses were completely clear in the normal control group.Lens opacification of Ⅴ grade was found in 11 eyes in selenite cataract model group,but no lens opacification of Ⅴ grade was seen in NAC preventive group,showing a significant difference(x2 =40.000,P＜0.05 ).In 30 days after experiment,Ⅳ- Ⅴ grades of cataracts were found in 20 eyes both in NAC + normal saline group and NAC treating group (x2=0.153,P＞ 0.05 ).Histopathological examination showed that lens structure was normal,and the separation between LECs and anterior capsule,the rupture of cellular membrane,deformation of cellular nuclei and the feature of lens fiber were seen in selenite cataract group,but the damage of lens was mild in the NAC preventive group.Ultrastructure of lens was obviously abnormal in selenite cataract group,NAC+normal saline group and NAC treating group.Expressions of caspase-3 and SOD in lens were significantly lower,but that of MDA was significantly higher in the selenite cataract group than the normal control group (P＜0.05) ;while those of the NAC preventive group were significantly different from selenite cataract group(P＜0.05).No significant difference was found in the expressions of caspase-3 and the levels of SOD and MDA between NAC+normal saline group and NAC treating group (P＞0.05 ). Conclusions Selenite can induce the apoptosis of LECs.NAC can evidently postpone formation of selenite cataract by increasing the activity of SOD,decreasing the level of MDA and the expression of caspase-3.However,NAC could not reverse selenite-induced lens damage.

ObjectiveTo investigate the effect of out-patient training combined with family training under doctor's instructions on children with cerebral palsy (CP).Methods80 CP children were selected as treatment group and trained one to three months by therapists at out-patient department, then continually trained at family by parents who received doctor's instructions 30 min once every two or three months. 60 CP children in hospital were selected as control group. Rehabilitative effects of two groups were compared.ResultsIn the first and third month after training completed, movement growth of treatment group was not different from that of control group (P>0.05), but in the sixth month, was significant different from that of control group (P<0.05). The effect of treatment group was better than that of control group.ConclusionOut-patient training combined with family training under doctor's instructions can decrease treatment expenses, and is convenient and effective for CP children.

A study was made on the pharmacokinetic regularity of effective components salvianolic acid B and ferulic acid in Salviae Miltiorrhizae Radix et Rhizoma (SMRR) and Chuanxiong Rhizoma(CR) in rats, so as to discuss the compatibility mechanism of Salviae Miltiorrhizae Radix et Rhizoma and Chuanxiong Rhizoma. Rats were randomly divided into three groups and intravenously injected with 50 mg x kg(-1) salvianolic acid B for the single SMRR extracts group, 0.5 mg x kg(-1) ferulic acid for the single CR extracts group and 50 mg x kg(-1) salvianolic acid B + 0.5 mg x kg(-1) ferulic acid for the SMRR and CR combination group. The blood samples were collected at different time points and purified by liquid-liquid extraction with ethyl acetate. With chloramphenicol as internal standard (IS), UPLC was adopted to determine concentrations of salvianolic acid B and ferulic acid. The pharmacokinetic parameters of salvianolic acid B and ferulic acid were calculated with WinNonlin 6.2 software and analyzed by SPSS 19.0 statistical software. The UPLC analysis method was adopted to determine salvianolic acid B and ferulic acid in rat plasma, including linear equation, stability, repeatability, precision and recovery. The established sample processing and analysis methods were stable and reliable, with significant differences in major pharmacokinetic parameters, e.g., area under the curve (AUC), mean residence time (MRT) and terminal half-life (t(1/2)). According to the experimental results, the combined application of SMRR and CR can significantly impact the pharmacokinetic process of their effective components in rats and promote the wide distribution, shorten the action time and prolong the in vivo action time of salvianolic acid B and increase the blood drug concentration and accelerate the clearance of ferulic acid in vivo.

Ultrasonic microbubbles were used to open blood-brain barriers (BBB) with a reversed and limited behavior feature in the study, which could improve the brain-targeted delivery of anti-tumor drugs. The glioma rat model was prepared. Low-frequency ultrasound was combined with microbubbles to affect the permeability of BBB compared with the permeability of independently administered Evans blue (EB) crossing BBB. Time point and length of ultrasound were investigated whether they affect the permeability of BBB and the damage of brain tissue. The effect of the growth time of glioma on BBB permeability was explored. Only glioma had a very little impact on BBB permeability. However, ultrasonic microbubbles opened the BBB with the features of temporary, limited and reversed behavior and improved EB and magnetic resonance imaging contrast agent penetrating BBB. A length of 30 s ultrasound is appropriate for opening BBB and no damage of brain tissue. Drugs should be injected before ultrasound so that they enter into brain as BBB opening. Ultrasonic microbubbles can open BBB effectively and safely, which improve drugs penetrating BBB under proper time point and length.
