OBJECTIVETo evaluate the operation time and clinical effect of three types of materials (i.e., total-etching adhesive, self-etching adhesive, resin-modified glass ionomer cement) that are used to bond removable thermoplastic appliances.

METHODSThirty malocclusion patients (156 attachments) with removable thermoplastic appliances were randomly divided into three groups, with 10 individuals each. Attachments of groups A and B were bonded using 3M Adper Single Bond 2 and 3M Adper Easy One, respectively; both adhesives utilized 3M Z350 nano composite resin. Attachments of group C was directly bonded using GC Fuji Ortho LC. The operation time of each attachment was recorded. Failure rates of adhesion were evaluated during adhesion, 1 month after treatment, and 6 months after treatment.

RESULTSThe operation time of group C was shorter than those of groups A and B (P<0.01). Significant difference of adhesion failure rates was not found among the three groups (P>0.05). No significant difference of adhesion failure rates was also observed in different times of the same group (P>0.05).

CONCLUSIONThe attachment stability of the three types of materials achieved satisfactory effects. However, the operation method of resin-modified glass ionomer cement is more concise and suitable for clinical promotion.

Objective To investigate the quantitative expression of mRNA levels of human NOV and WT1 genes in renal cell carcinoma ( RCC). Methods Using quantitative real-time RT-PCR analysis, we quantified NOV and WT1 mRNA levels in the samples from 57 patients (40 men and 17 women; mean age,65 years) with RCC. Of them,39 cases had T1 stage tumor, 13 had T2 stage and 5 had T3a stage by UICC pathologic staging;and 14 cases had G1 tumor,23 had G2 and 20 had G3 by Fuhrman grading. The expression levels of NOV and WT1 genes,and their association were analyzed. Results The median level of NOV mRNA expression was significantly lower in RCC ( 1. 17) than in normal kidney tissue (4. 32, P

This study was aimed to compare the antioxidant activity of puerarin and 3 other flavonoid compounds, and to investigate their structure-activity relationship. The intragastric administration of 4 kinds of typical flavonoids compounds (soybean element, puerarin, quercetin and rutin) were given to mice, respectively. The model mice of acute hepatic injury were established with intraperitoneal injection of 0.1% carbon tetrachloride (CCl4) after 7 days. After 18 h fasting, liver tissues were removed. The histomorphology was observed after paraffin sectioning and hematoxylin-eosin staining. The activities of alanine aminotransferase (ALT), aspartate aminotransferase (AST), gamma-glutamyl transpeptidase (GGT) and alkaline phosphatase (ALP) in serum were detected with automatic biochemical analyzer. The content of malondialdehyde (MDA), the activities of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) in liver tissues were detected with homogenization. The pathological results of liver tissues showed that hepatic damages were decreased in all 4 medicine treatment groups compared with the model group, but there were no significant differences among these treatment groups. The results of blood serum bio-chemical analysis showed that compared with the model group, puerarin and quercetin could decrease the activities of ALT, AST and GGT in serum significantly (P < 0.05, orP < 0.01). There were no content changes of ALP. In the soybean element group, only the activities of ALT and AST decreased obviously (P < 0.05, orP < 0.01). There was no obvious change in the serum of mice in the rutin treatment group. The homogenate detection results of liver tissues showed that compared with the model group, quercetin and rutin significantly lowered MDA (P < 0.05), increased SOD and GSH-Px (P < 0.05, orP < 0.01); while soybean element and puerarin only improved GSH-Px levels (P < 0.05, orP < 0.01). It was concluded that the antioxidant capacity of quercetin was better than that of soybean element, puerarin and rutin, which may be related to its structure. Compared with 3 other chemical compounds, quercetin had more polyhydroxies and its polyhydroxies were not glycosylated, which suggested that the structure of quercetin may be closely related to its antioxidation activity.

Objective To summarize the medical rescue of Chinese Government Medical Team (Chongqing) in Nepal earthquake region in order to explore the work pattern of transnational medical rescue,and improve the rescue efficiency.Methods From the experience about the post-earthquake medical rescue of Chinese Government Medical Team (Chongqing) in Nepal in 2015,several aspects were worthy to summarize such as the establishment of medical team,the layout of camp site,the work algorithm and process,with the analysis of injury feature and outcome of treatment.Results Under the setting of efficient organization and rational assignment of professional work,special working rules,the mutual transfer treatment and multi-disciplinary treatment were employed for 737 emergency patients.Of them,128 patients were hospitalized (including 63 patients completely recovered,56 patients were of clinical improvement,and 9 patients were critically ill transferred to other hospital for advanced treatment),and post-traumatic complication occurred in 48 cases without death.In addition,148 operations were carried out successfully.Conclusions The earthquake disaster has specific feature such as suddenness,a host of casualties and poor rescue conditions,and overseas rescue is with the presence of the language barrier,the difference in living habit,and the lack of coordination with local rescue system,therefore,rationally assigning personnel and resources and establishing work pattern with flexibility,orderly and good communication are the key to promote the efficiency of transnational medical rescue for the injured patients in earthquake region.

This study was aimed to summarize the adverse drug reaction (ADR) caused by the toxicity of Tripterygium Wilfordiiand its preparations, in order to explore possible relationship betweenTripterygium Wilfordiifactors and reported ADR. Relevant articles on toxicity ofTripterygium Wilfordiiand its preparations were systematically searched in 5 databases, including the Pubmed, CNKI,Wanfang Data, VIP Data and Sinomed from the database was established until Feb 25th, 2014. And then, the randomized controlled trials (RCTs) were systematically collected, analyzed and summarized. The results showed that there were 260 RCTs with 13301 patients included. The outcome of data analysis showed that ADR rates of digestive system and reproductive system of RCT1 and RCT2 were different. ADR rates (per hundred people) in RCT1 and RCT2 were as follows: digestive system were 14.73 and 12.26, reproductive system were 8.25 and 8.00, liver was 6.50 and 5.66, kidneys were 6.79 and 3.03, blood system were 6.73 and 6.50, cardiovascular system were 2.35 and 0.67, skin and mucous system were 11.42 and 4.78, respectively. Articles on rheumatoid arthritis (RA) of both RCT1 and RCT2 were the highest, which occupied 22.17% in RCT1 and 63.16% in RCT2. The corresponding ADR rates were 34.18 and 27.26. The standard deviation (SD) of 7 disease types, which were RA, IgA nephropathy, nephritis, nephrotic syndrome (NS), diabetic nephropathy, psoriasis, lichen and rashes, as well as uterine fibroids, was 8.69 in RCT1. The SD of RA, IgA nephropathy, psoriasis, lichen and rashes was 7.11 in RCT2. It was concluded that the possible ADR distribution ofTripterygium Wilfordiiand its preparations were the highest in the digestive system, reproductive system and liver. Besides, different diseases (i.e., RA, nephritis, NS, and etc.) had huge differences with their correspondent ADR rates. Therefore, it was suggested that specific measures should be taken to select the appropriateTripterygium Wilfordiipreparation, protect the stomach and liver during the application ofTripterygium Wilfordiiand its preparations. During medication, attentions should be paid to the reaction of patients. Stop the medication when necessary to minimize ADR rates to the lowest.

OBJECTIVE: To evaluate the advantage of Gukangling Decoction (GKLD), a compound traditional Chinese herbal medicine, combined with technetium [(99)Tc] methylene diphosphonate injection ((99)Tc-MDP) in treating osteoporosis in rabbits. METHODS: A rabbit model of osteoporosis was established by intramuscular injection of dexamethasone (DX). Fifty-six rabbits were divided into 8 groups: Group A, B, C, D, E, F, G and H. Rabbits in groups A and B were intramuscularly injected normal saline as normal control, groups C and D were untreated groups, rabbits in group E were treated by (99)-MDP, rabbits in group F were treated by aminodiphosphate, rabbits in group G were treated by GKLD, and rabbits in group H were treated by (99)-MDP and GKLD. Rabbits in groups A and C were executed to demonstrate the establishment of the rabbit model of osteoporosis at the 8th week of experiment. Rabbits in the other six groups were executed after 16-week experiment (8-week treatment), and then bone structure and cell shape were observed by electron microscope, X-ray, CT and emission computed tomography (ECT). Bone density, biomechanical parameters, the levels of bone specific alkaline phosphatase (BALP) and bone Gla protein (BGP) were measured too. RESULTS: After 8-week of intramuscular injection of DX, the bone trabecula in group A were regular and showed normal configuration, while the bone trabecula in group C were sparse, ruptured and showed damaged form. The bone density and biomechanical parameters in group A were higher than those in group C, indicating that the rabbit model of osteoporosis was established successfully. At the 9th week of experiment, the results of cell pathology in group D showed that the bone trabeculas were sparse, ruptured, defected or had hollow section, but the bone trabeculas in group B were regular and dense. The bone trabeculas in groups H and E were restored, and were thicker than those in group D. The bone quality in groups H and E was better than group D significantly, the bone quality in group F was better than group G, and the bone quality in group G was better than group D slightly. CONCLUSION: GKLD combined with (99)-MDP had superiority in treating osteoporosis of rabbits as compared with the respective single therapy.

In this report, highly water soluble esters of scutellarin with different molecular weight polyethylene glycol (PEG) were synthesized in order to improve the bioavailability of scutellarin. The physicochemical properties, the stabilities under different conditions and the in situ intestinal absorption in rats of the conjugates were investigated. By PEG modification, the greatly increased water solubility and desirable partition coefficient of scutellarin were obtained. These compounds function as prodrugs i. e. breakdown occurred in a predictable fashion: the t1/2 of them in PBS buffer at pH7.4 was above 12 h (37 degrees C) in vitro, while in plasma a rapid breakdown was observed, with a t1/2 of about 1. 5-3 h. The stabilities of the prodrugs were improved according to the increase of the molecular weight of PEG, thus, PEGylated prodrugs with desirable rates of hydrolysis could be obtained by the use of variable molecular weight PEGs. The PEGylation could enhance the absorption of scutellarin in rat intestine, and the absorption of scutellarin and its PEG conjugates by intestine was mainly via passive transport, for when the concentration was raised, the uptake did not appear saturable, and the permeability coefficient kept at an equilibrium level. When the molecular weight of PEG increased from 200 to 1000 Da, the absorption of the conjugates decreased. In conclusion, by overall consideration of the yield, stability and absorption, the present authors estimate that the PEG molecular weight used for the PEGylation of scutellarin should be within the range of 400-1 000 Da.

OBJECTIVE: To investigate the ING1 gene mutation status in human laryngeal squamous cell carcinoma(LSCC), and the association of p33(ING1b) protein expression with p53 protein expression. METHOD: DNA of LSCC tissue was extracted, and nucleotide of the second exon was amplified and sequenced to determine the chromosome status. The p23(ING1b) and p53 protein expression were detected by immunohistochemistry and the association between them were analyzed. RESULT: No mutation was detected in ING1 gene, but a single polymorphism from GGG to AGG at codon 170 of ING1 gene was found in 2 of the 25 LSCC tissues. The immunohistochemical analysis showed that 4 had positive p33(ING1b) expression. No association was found between p33(ING1b) expression and LSCC clinical features, or between p53 and clinical features. However, significant difference was found between p33(ING1b) and p53 expression. p33(ING1b) tended to be negative in p53 expression positive tissue. CONCLUSION ING1 gene mutation appears rare in LSCC. In normal physical condition, p33(ING1b) may play a synergistic effect with p53 protein.

OBJECTIVETo study the immunohistochemical expression of S100A1, GLUT-1 and Cavolin-1 and its diagnostic significance in renal tumors with oncocytic features.

METHODSTissue microarray and immunohistochemical staining for S100A1, GLUT-1 and Cavolin-1 were carried out in 59 cases of renal tumors with oncocytic features, including 19 cases of renal oncocytoma, 15 cases of clear cell renal cell carcinoma (CCRCC) with eosinophilic cells, 11 cases of eosinophilic variant of chromophobe renal cell carcinoma, 7 cases of oncocytic papillary renal cell carcinoma and 7 cases of epithelioid angiomyolipoma.

RESULTSS100A1 was expressed in renal oncocytoma, with a positive propotion of 16/19 (including 14 cases showing widespread and strong positivity). On the other hand, the rate of expression of S100A1 was 2/11 in eosinophilic variant of chromophobe renal cell carcinoma, 10/15 in CCRCC with eosinophilic cells, 3/7 in oncocytic papillary renal cell carcinoma and 6/7 in epithelioid angiomyolipoma (P>0.05). The difference of S100A1 expression between renal oncocytoma and eosinophilic variant of chromophobe renal cell carcinoma was statistically significant. GLUT-1 was located in cell membrane, with a positive rate of 13/15 in CCRCC with eosinophilic cells, 7/19 in renal oncocytoma, 4/7 (weak) in oncocytic papillary renal cell carcinoma, 1/11 in eosinophilic variant of chromophobe renal cell carcinoma and 0/7 in epithelioid angiomyolipoma. The rate of expression of Cav-1 was 6/15 in CCRCC with eosinophilic cells, 2/7 in oncocytic papillary renal cell carcinoma, 5/7 in epithelioid angiomyolipoma, 2/11 (weak) in eosinophilic variant of chromophobe renal cell carcinoma and 0/19 in renal oncocytoma. S100A1 showed high sensitivity and 50% specificity in the diagnosis of renal oncocytoma. GLUT-1 and Cav-1 showed high specificity and sensitivity in the diagnosis of CCRCC and epithelioid angiomyolipoma.

CONCLUSIONSS100A1 is widely expressed in various oncocytic renal neoplasms and helpful in differential diagnosis of renal oncocytoma from eosinophilic variant of chromophobe renal cell carcinoma, but not from other 3 oncocytic renal tumors. Overexpression of GLUT-1 can be used in distinction between CCRCC and renal oncocytoma. Cav-1 is widely expressed in CCRCC and epithelioid angiomyolipoma but not in renal oncocytoma. Cav-1 expression thus rules out renal oncocytoma.
