Chinese Pharmacological Bulletin 2019;35(12):1743-1747
Aim To explore the effect of Trillium tschonoskii Maxim (TTM) on the expression of miR-NA-155-3p in rats with brain aging induced by D-gal. Methods Fifty SD rats were divided into five groups randomly. The rats were administered with 0. 9% normal saline (NS) subeutaneously every day in control group, 200 mg • kg • d-1 of D-galactose (D-gal) daily inD-galmodelgroup,and50,100and200mg • kg • d-1 of TTM by gavage 2 hours before D-gal injection everyday in TTM treatment groups for 6 weeks. After 5 weeks, Morris water maze was used to test the ability of spatial learning and memory every day. At the 6th week, rats were sacrificed arid hippocampi were tested by Nissl staining and 8-OHdG immunohistochemical (8-OHdC) staining. The expression of miR-155-3p was determined by Real-time PCR, and the levels of Rheb. mTOR, p-inTOR and p70S6K were detected by Western blot. Results The length of escape latency time and path distance in five groups showed a trend of shortening gradually in the orientation navigation experiments. The average escape latency and the distance in D-gal group were longer than those in control group and TTM group (P <0. 01 and 0. 05) , and the number of crossing platform limes less too (P < 0. 05). The arrangement of neurons was irregular and the intercellular space widened in D-gal group compared with those in TTM group by HE staining. There were more Nissl particles in neurons of the hippocampal CA1 area in con-trol group than that in D-gal group, and TTM treatment could increase the number of Nissl bodies-induced by D-gal. Compared with control group, the fluorescence density of 8-OHdG in D-gal group significantly in-creased (P <0. 01) , while that in TTM group was lower than that in D-gal group (P < 0. 05). The expression of miR-155-3p in the hippocampi in D-gal group was significantly higher than that in normal group (P < 0. 05) , while TTM treatment could alleviate D-gal-in-duced increase of miR-155-3p (P < 0. 05) , followed by an increase of the levels of Rheb and p70S6K, and decrease of mTOR. Conclusions The expression of miR-155-3p increased in the hippocampi of aging rats induced by D-gal. TTM could execute the anti-aging process of brain and down-regulate the level of iniR-155-3p through Rheb/mTOR/p70S6K signaling pathway.

The aimed of this study was to prepare stabilized thiomers to overcome the poor stability character of traditional thiomers. Poly(acrylic acid)-cysteine (PAA-Cys) was synthesized by conjugating cysteine with poly(acrylic acid) and poly(acrylic acid)-cysteine-6-mercaptonicotinic acid (PAA-Cys-6MNA, stabilized thiomers) was synthesized by grafting a protecting group 6-mercaptonicotinic acid (6MNA) with PAA-Cys. The free thiol of PAA-Cys was determined by Ellmann's reagent method and the ratio of 6MNA coupled was determined by glutathione reduction method. The study of permeation enhancement and stabilized function was conducted by using Franz diffusion cell method, with fluorescein isothiocyanate dextran (FD4) used as model drug. The influence of polymers on tight junctions of Caco-2 cell monolayer was detected with laser scanning confocal fluorescence microscope. The results indicated that both PAA-Cys and PAA-Cys-6MNA could promote the permeation of FD4 across excised rat intestine, and the permeation function of PAA-Cys-6MNA was not influence by the pH of the storage environment and the oxidation of air after the protecting group 6MNA was grafted. The distribution of tight junction protein of Caco-2 cell monolayer F-actin was influenced after incubation with PAA-Cys and PAA-Cys-6MNA. In conclusion, stabilized thiomers (PAA-Cys-6MNA) maintained the permeation function compared with the traditional thiomers (PAA-Cys) and its stability was improved. The mechanism of the permeation enhancement function of the polymers might be related to their influence on tight junction relating proteins of cells.

OBJECTIVETo search all studies that had been published in the world with regarding to the effectiveness of the extent of intralesional curettage and wide excision for recurrence rate and complications and comparative functional outcomes in patients with giant cell tumours (GCT) of the distal radius and analyze them which were in high quality by means of Meta analysis, in order to give some evidences for the choice of method dealing with giant cell tumors GCT in surgery.
METHODSCochrane central register of controlled trials(Issue 8 2014), PubMed(1970-01-01/2013-01-01), Ovid (1970-01-01/2013- 01-01), Elsevier (1970-01-01/2013-01-01), CNKI (1970-01-01/2013-01-01) were searched. Including intralesional curettage and wide excision were performed to treat giant cell tumors (GCTs) of the distal radius in the literatures, selecting on meet eligibility in the standard literatures underwent strict quality assessment. The Meta-analysis was performed with software RevMan5.0 from the Cochrane collaboration. Additionally, the analysis checked the heterogeneity of data. The effectiveness of the extent of intralesional curettage and wide excision for recurrence rate and complication in patients with giant cell tumours of the distal radius were evaluated and Odds Ratio was calculated.
RESULTSSeven relevant articles were identified involving total 163 cases. Among them, 92 cases were intralesional curettage (PMMA, n = 54; bone graft, n = 33; no PMMA or bone grafts, n = 5) and 71 cases were wide excision. The patients in the intralesional curettage group had a higher recurrence rate [OR = 3.87, 95% CI (1.42, 10.53)],especially for Campanacci grade 3 GCTs [OR = 10.12, 95% CI (1.57, 65.27)], yet fewer major complications [OR = 0.13, 95% CI (0.04, 0.40)] than the wide excision group. The use of PMMA versus bone graft did not affect the recur- rence rate [OR = 0.96, 95% CI (0.26, 3.56)]. By selecting the system evaluation of MSTS, the VAS and dynamometer, the result showed that the intralesional curettage group was equivalent or preferable to wide excision in terms of function rehabilitation.
CONCLUSIONBased on data obtained from the limited number of studies available, intralesional curettage appears to be moreappropriate for the treatment of local lesions (Grade 1 and 2) than Grade 3 GCTs of the distal radius. Moreover, PMMA was not additionally effective as an adjuvant, the intralesional curettage group was found to be equivalent or preferable to wide excision in terms of function rehabilitation.

The second and third group were better than the first group (χ2=15. 71, P<0. 01;χ2=15. 27, P<0. 01);the treatment effect of the second and third groups was no significant difference (χ2=0. 02, P>0. 05).
CONCLUSlON:lnfants with congenital nasolacrimal duct obstruction should distinguish between ages, taking different treatments, in order to obtain a better therapeutic effect, and lacrimal pressure washing is the preferred way of treating infants with congenital nasolacrimal duct obstruction.
8. Effect of extract of Trillium tschonoskii Maxim on ciliary neurotropic factor and its receptor α in rats suffering from spinal cord injury
Medical Journal of Chinese People's Liberation Army 2015;40(8):622-626
Objective To investigate the effect of Trillium tschonoskii Maxim extract on the expression of ciliary neurotrophic factor (CNTF) and its receptor (CNTFRα) after spinal cord injury in rats. Methods Forty-five rats were equally and randomly divided into control group (group A), model group (group B) and Trillium tschonoskii Maxim treated group (group C). Allen's weight drop method was used to reproduce acute spinal cord injury (SCI) model in rats of the group B and C. In group C, the rats were gavaged with Trillium tschonoskii Maxim extract 2 weeks before the injury, while rats in group A and B were fed a same quantity of distilled water.1, 7 or 14 days after injury, the rats were sacrificed to observe the structure of nerve cells after HE and Nissl staining, and the expression of CNTF and CNTFRα with immunohistochemical method, RT-PCR and Western blotting. Results HE staining showed that the structure of spinal cord in the the rats group C was more discernible, with milder edema and necrosis of nerve cells, as compared with that of group B. Nissl staining showed that Nissl bodies were decreased or disappeared in anterior horn motor neurons in both group B and C, but it was significantly less marked in group C than that in group B. Immunohistochemical staining, Western blotting and RT-PCR revealed that the protein and mRNA of CNTF and CNTFRα were positively expressed in rats of every group. The mRNA levels of CNTF and CNTFRα in group C were higher than those in group B. Conclusions Extract of Trillium tschonoskii Maxim can up-regulate the expression of CNTF and CNTFRα, and plays a protective role against injury to spinal cord.

OBJECTIVETo explore evolution rules of phlegm and blood stasis syndrome ( PBSS) in hyperlipidemia and atherosclerosis (AS) using NMR-based metabolic profiling and metabonomic approaches based on formulas corresponding to syndrome.
METHODSTotally 150 SD rats were divided into the normal group, the model group, the Erchen Decoction (ED) group, the Xuefu Zhuyu Decoction (XZD) group, the Lipitor group, 30 in each group. The hyperlipidemia and AS rat model was duplicated by suturing carotid artery, injecting vitamin D3, and feeding with high fat diet. ED and XZD were used as drug probes. Blood samples were withdrawn at week 2, 4, and 8 after modeling. Blood lipids, blood rheology, histopathology and metabolomics were detected and analyzed. Results Results of blood lipids and pathology showed hyperlipidemia and early AS rat models were successfully established. At week 2 after modeling, levels of total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C) significantly increased, which reached the peak at week 4 and maintained at higher levels at week 8. ED exerted obvious effect in improving TC and LDL-C levels of early models, while XZD could greatly improve levels of TC and LDL-C of late models. Rheological results showed at week 2, there was no significant difference in whole blood viscosity, plasma viscosity, or hematocrit between the model group and the normal group (P > 0.05). At week 4 partial hemorheological indicators (such as plasma viscosity) were abnormal. Till week 8 whole blood viscosity, plasma viscosity, and hematocrit were significantly abnormal (P <0. 05, P < 0.01). As time went by, whole blood viscosity, plasma viscosity, and hematocrit showed gradual increasing tendency in the ED group, while they showed gradual decreasing tendency in the XZD group. Results of metabonomics showed significant difference in spectra of metabolites between the normal group and the model group. As modeling time was prolonged, contents of acetyl glucoprotein and glucose in the model group increased in late stage, which was in. line with results of blood lipids and hemorheology. ED showed more obvious effect in early and mid-term modeling (at week 2 and 4), and increased contents of partial metabolites (such as choline, phosphatidyl choline, glycerophosphocholine), but these changes in the XZD group were consistent with those of the model group. In late modeling (at week 8) XZD showed more obvious effect in improving contents of lactic acid, acetyl glycoprotein, LDL, creatine, choline, and glucose.
CONCLUSIONSED and XZD not only showed regulatory effects on lipid disorders, but also could improve dysbolism of Chos. In formulas corresponding to syndrome, damp-phlegm was main pathogenesis of hyperlipidema and AS in early and mid stages. Blood stasis syndrome began to occur along with it progressed. Phlegm can result in blood stasis and intermingles with stasis. Phlegm turbidity runs through the whole process.
