OBJECTIVETo dynamically observe the effect of Shenshuai Mixture (SM) on repair of kidney in acute renal failure (ARF) rats.
METHODSMale SD rats were divided into 4 groups randomly, the normal group, the SM group, the verapamil group and the model control group. Except those in the normal group were treated with normal saline without modeling, all remaining rats, after being made into ARF model by intra-muscular injection of glycerin, were treated with SM, verapamil and normal saline respectively via gastrogavage. Renal function, renal pathology, mRNA expression of epidermal growth factor (EGF) and protein expression of proliferating cell nuclear antigen (PCNA) were detected once every day from the 1st day to the 5th day. Results (1) BUN and Scr levels increased markedly 24 hrs after modeling, but the Scr level in the two treated groups was significantly lower than that in the model group (P < 0.05). Compared with that in the model group and the verapamil group, renal function was better in the SM group on the 3rd day (P < 0.01), and approach to normal level on the 5th day. (2) Renal pathological changes alleviated in every phase of ARF in the SM group than that in the model group, especially part of tubule regeneration could be seen on the 3rd day (metaphase), and renal structure was rehabilitated on the 5th day (convalescence), prior to those in the model group. (3) At the 3rd day expression of EGF mRNA and PCNA in tubule epithelial cell (TEC) increased remarkably in the SM group, higher than those in the model and verapamil group (P < 0.05).
CONCLUSIONSM could promote renal tissue regeneration and rehabilitation, and shorten the course of ARF through up-regulating mRNA expression of EGF in TEC.

OBJECTIVETo observe the effect of the experiential compound prescription Shenshuai compound medicine (SSCM) on acute renal failure (ARF) rats, and expose its mechanism.
METHODMale SD rats were allocated into four groups at random. Except normal group, the others were injected glycerin into the musculi to induce a model of ARF. At the same time, rats in normal and model groups were given a dose (10 mL x kg(-1)) of normal saline; rats in the other two groups were given verapamil (Vp) 40 mg x kg(-1) x d(-1) and SSCM 22.5 mg x kg(-1) x d(-1) respectively by gastric gavages. In this way they were killed at 24 h after injecting glycerin.
RESULTIn contrast with model group, SSCM and Vp could ameliorate the renal function of acute tubular necrosis (ATN) rats markedly, in a way protect the renal inherent cell ultrastructure such as tubular epithelial cell etc at ATN early-stage; especially SSCM could enhance NO contents in serum, and was reduce ET levels inplasma, evidently cut down TNF-alpha contents in serum, and was partly superior to Vp.
CONCLUSIONIt is indicated that SSCM can adjust thebalance of contract and stretch blood vessal active substance and clear away initiate inflammatory medium, consequently alleviate renal pathological changes, prevent and treat ARF.

Objective To evaluate the comparative effectiveness and safety of bisphosphonates.Methods PubMed and Cochrane Database of Systematic Review were electronically searched for Meta -analysis and network Meta-analysis about the effectiveness and safety of bisphospho-nates.The randomized controlled trials ( RCTs ) comparing different bi-sphosphonates were manually searched.We then complete the descriptive analysis about the direct and indirect comparison between bisphospho-nates.Results Seventeen Meta-analyses were included, including 1 Meta-analysis comparing different bisphosphonates, 10 Meta-analyses comparing bisphosphonates and placebo, and 6 network Meta-analyses. The results of direct comparison showed that there was no significant difference between different bisphosphonates in effectiveness and safety. The results of indirect comparison showed that zoledronic acid, alendr-onate or zoledronic acid, alendronate, risedronate ranked first in preven-ting vertebral fracture, hip fracture, wrist, non -hip -non -vertebral fracture among different bisphosphonates, respectively.Zoledronic acid, zoledronic acid, etidronate ranked highest in causing any gastrointestinal adverse events, nausea, and discontinuation due to adverse drug reactions among different bisphosphonates, respective-ly.Conclusion Bisphosphonates are effective and safe medications for treating osteoporosis.Although zoledronic acid ranked highest in preventing fracture, it was also more likely to cause gastrointestinal adverse events.However, the quality of a body of evidence comparing different bisphosphonates is low.More well -designed clinical studies are needed to support above conclusion.

OBJECTIVETo investigate the effect of small interfering RNA (siRNA) targeting human vascular endothelial growth factor (hVEGF) on A549 cell growth in nude mice and angiogenesis on chorioallantoic membrane (CAM) assay.
METHODSThree pairs of hVEGF siRNA-plasmid and non-silencing-plasmid were constructed, and transfected into A549 cells through lipofectamine 2000, respectively. The most effective pair of hVEGF siRNA-plasmid was selected by ELISA and real-time RT-PCR. A549 cells transfected with selected hVEGF siRNA- plasmid, A549 cells transfected with non-silencing-plasmid and A549 cells without transfection were inoculated into nude mice, respectively. Chick embryos were randomly divided into four groups and CAM was treated by different solutions for 48 h: culture media DMEM as negative control group,un-transfected A549 cell culture supernatants as positive control group, hVEGF siRNA A549 cell culture supernatants as hVEGF siRNA group and nonsilencing siRNA A549 cell culture supernatants as non-silencing siRNA group. The CAMs were harvested on d12 for microscopic assays.
RESULTCompared with control group, hVEGF siRNA-plasmid induced 48% reduction in hVEGF secretion by A549 cells accompanied by 70% reduction in hVEGF mRNA. Compared with non-silencing siRNA group, the mean tumor volume of murine xenograft was reduced by 58% in hVEGF siRNA group; time for xenografts growing to 50 mm(3)was delayed by 5.4 d. hVEGF contents in xenograft were reduced by 54%; but mean doubling time of tumors and the growth rate of tumors were not significantly reduced. In CAM assays, hVEGF content was zero in negative group, and in hVEGF siRNA group that was 40%-44% of non-silencing siRNA group or positive group; vessels branch points of CAM in hVEGF siRNA group or non-silencing siRNA group or positive group were increased by 45%-55% compared with negative group; total vessel length of CAM in hVEGF siRNA group was increased by 53% compared with negative group, while in non-silencing siRNA group or positive group that was increased by 97% or 99%. Compared with negative control group, the proliferation of microvessels was increased when cell culture supernatant with hVEGF was added in hVEGF siRNA group, significant proliferated vessels were observed in non-silencing siRNA group or positive group.
CONCLUSIONA plasmid-mediated hVEGF siRNA has been constructed and verified, which can effectively downregulate the expression of hVEGF in human A549 cells, resulting in the inhibition of angiogenesis. hVEGF siRNA can delay initial growth of A549 tumor xenograft but not reduce the growth rate.

OBJECTIVEHyperphenylalaninemia (HPA) is an inborn error of metabolism in which the hydroxylation of phenylalanine (Phe) to tyrosine is disturbed. Accumulation of Phe leads to severe mental and psychomotor retardation. (1)H magnetic resonance spectroscopy ((1)HMRS) is a novel non-invasive method to quantitate the brain metabolites besides Phe concentration in HPA patients. And it could be acquired conveniently on clinical MRI routine scanners. This study aimed to investigate the correlation between blood Phe ([Phe](blood)) and [Phe](brain), the characteristics of blood-brain Phe metabolism and its impacts on mental retardation.
METHODTotally 32 untreated patients diagnosed with HPA were studied, including 18 boys and 14 girls (age ranging from 33 days to 13 years). The patients were divided into two groups: elder than 4 months old (n = 22) and younger than 4 months old (n = 10). (1)HMRS were performed in all patients. [Phe](brain) were measured by absolute [Phe](brain) using Creatinine as an internal reference. [Phe](blood) were measured and developmental quotient (DQ) or intelligence quotients (IQ) were evaluated.
RESULT(1) [Phe](brain) measured by (1)HMRS ranged from 0.0640 to 0.6296 (M = 0.1542) while the [Phe](blood) was from 0.3804 to 2.5140 mmol/L (M = 1.5210 mmol/L) in all the 32 cases of HPA patients. (2) There was a positive linear correlation (r = 0.6103 (P < 0.01)) between [Phe](blood) and [Phe](brain). And there were interindividual differences in [Phe](brain) in several patients. (3) Variable mental retardation were observed in 23/32 cases in this study. (4) There was a negative correlation between [Phe](blood) and [Phe](brain) to the mental retardation (r(blood) = -0.5045, r(brain) = -0.6471 (P < 0.01)) in 22 cases of the HPA patients older than 4 months. And [Phe](brain) had more significant correlation with mental development than [Phe](blood).
CONCLUSIONThe [Phe](blood) could correspondingly represent the [Phe](brain) in most HPA patients. The Phe concentration could reflect the degree of mental retardation substantially in 22 cases with HPA older than 4 months. And the [Phe](brain) could more accurately illustrate it. (1)HMRS can be used to quantitate intracerebral Phe concentrations non-invasively in HPA patients. Preliminary findings suggest that interindividual variations in the kinetics of Phe uptake and metabolism do exist. (1)HMRS has great clinical significance in understanding the mechanism of HPA patient's mental retardation, providing proper objective standards for better diagnosis and treatment of HPA patients.
