Background: Endoscopic surgery of Western medicine has developed rapidly in treating ureteral calculi while traditional Chinese medicine (TCM) therapy also has its advantage, thus the integrated traditional Chinese and Western medicine therapy may have an even better efficacy in dealing with this problem. Objective: To observe the clinical effects of sequential therapy of Quantong Recipe, a compound traditional Chinese herbal medicine, combined with ureteroscopic laser lithotripsy on ureteral calculi. Design, setting, participants and interventions: A total of 151 patients with ureteral calculi (stone diameter of 3 to 21 mm) from Department of Urology, Yueyang Hospital of Integrated Traditional Chinese and Western Medicine, Shanghai University of Traditional Chinese Medicine were included, of which 106 patients with stone diameter of 3 to 10 mm were treated with Quantong Recipe for the first two weeks. Twenty patients with unexpelled stones and 45 patients with stone diameter of more than 10 mm were treated with ureteroscopic laser lithotripsy. The 65 patients except one open operation were divided into regular treatment group (32 cases) and regular treatment combined with Quantong Recipe group (32 cases) after lithotripsy. The efficacy was assessed after one week. Main outcome measures: Cure rate in the patients with stone diameter of less than 10 mm after two-week Quantong Recipe treatment was calculated, and clearance rate in the patients with residual stone for ureteroscopic laser lithotripsy after one-week Quantong Recipe treatment was also observed. Results: After taking Quantong Recipe for two weeks, the stones in 86 patients were completely discharged, and the stones in 6 patients were not completely discharged, but the unexpelled stones had moved down more than one segment of ureteral stenosis; the total response rate was 86.79% (92/106). The 64 patients with stones unexpelled or with stone diameter of more than 10 mm were treated with ureteroscopic laser lithotripsy, and the clearance rate of residual stone was 93.8% in regular treatment combined with Quantong Recipe group, and was 71.9% in regular treatment group, and there was a significant difference between the two groups (P<0.05). Conclusion: Sequential therapy of Quantong Recipe integrated with ureteroscopic laser lithotripsy demonstrates a significant advantage of integrated traditional Chinese and Western medicine therapy in treating ureteral calculi.

OBJECTIVE: To evaluate the genetic damage induced by occupational chromate exposure, and to analyze the association between human 8-oxoguanine-DNA N-glycosylase 1(hOGG1) polymorphisms and genetic damage in population with chromate exposure. METHODS: A total of 136 chromate exposed workers were recruited as exposure group by judgmental sampling method, and 156 workers without chromate and other occupational hazard factors exposure were recruited as control group. The whole blood chromium(WB-Cr) level was measured by inductively coupled plasma mass spectrometry. Urinary 8-hydroxy-2′-deoxyguanosine(8-OHdG) was determined by enzyme-linked immunosorbent assay. Four single nucleotide polymorphisms of hOGG1 gene were genotyped by the matrix assisted laser desorption ionization/time of flight mass spectrometry. RESULTS: The WB-Cr level was higher in the exposure group than that in the control group(meclian: 3.41 vs 0.90 μg/L, P<0.01). The urinary 8-OHdG level was higher in the exposure group compared with that in the control group(meclian: 6.02 vs 4.72 μg/g·creatinine, P<0.01). In study subjects(exposure group and control group), after adjusting the potential influencing factors such as age, body mass index(BMI), gender, smoking and drinking, chromate exposure might be a risk factor for increasing urinary 8-OHdG level(P<0.05), and the recessive models of rs293796 and rs13096551 were observed as risk factors of increasing urinary 8-OHdG level(P<0.05). In chromate exposure group, the additive and recessive models of rs293796 and the recessive model of rs13096551 were observed as risk factors of increasing urinary 8-OHdG level(P<0.05), while the dominant model of rs3219008 was protective factor of increasing urinary 8-OHdG level(P<0.05), after adjusting the potential influencing factors such as age, BMI, gender, smoking, drinking. However, after multiple Bonferroni correction tests, only the recessive model of rs293796 was the risk factor of increasing urinary 8-OHdG level in the exposed group(P<0.01). There was significant interaction between chromate exposure and rs293796 on urinary 8-OHdG(P<0.01). CONCLUSION: The rs13096551 and rs293796 of hOGG1 were associated with the alteration of urinary 8-OHdG level induced by chromate. There was interaction between rs294796 of hOGG1 and chromate exposure on urinary 8-OHdG level.

BACKGROUND:Fibroblast-like synoviocytes (FLS) in the synovial lining layer are related to the cell proliferation, invasion, migration and apoptosis as well as bone resorption in rheumatoid arthritis. OBJECTIVE:To compare the migration and invasion abilities of FLS (MH7A) in rheumatoid arthritis and normal FLS (HFLS). METHODS:The capacities of cell migration and invasion were evaluated by Transwell cell migration and invasion assays. The primers of the indicated microRNAs were designed and synthesized, and the expression levels of miRNAs were determined by real-time PCR according to the SYBR?PrimeScript?miRNA RT-PCR Kit instruction. RESULTS AND CONCLUSION:MH7A possessed stronger migration and invasion abilities than HFLS. Compared with HFLS, obviously upregulated miR-132, -155, -203, -223 and -124, and significantly downregulated miR-15a, -16, 18a, -19a, -26a and -146a were found in MH7A. These findings suggest that the differentially expressed 11 kinds of rheumatoid arthritis-associated miRNAs participate in the pathogenesis of rheumatoid arthritis probably by enhancing the migration and invasion capacities of MH7A.

Randomized controlled trial (RCT) can be designed as explanatory trial and pragmatic/practical trial (PCT) for clinical effect evaluation.The pragmatic/practical trial reflects the intervention effect under actual clinical condition,which has relatively good extrapolation,but its internal validity is relatively poor.In contrast,explanatory trials conducted under ideal conditions have better inner validity but inferior external validity.However,in the design of RCT,PCT and explanatory trials are not always opposite.Many RCTs have the properties of the two designs at the same time,Pragmatic-explanatory continuum indicator summary (PRECIS) can be used in the design of RCT for the balance between internal validity and external validity.There are few available reports about the application of PRECIS in China at present,so this paper summarizes the basic principles,characteristics of PRECIS and the application of PRECIS in order to provide reference for the clinical trial design in China.

Biomonitoring can be applied to assess internal exposure and environmental exposure by exposure markers with providing internal exposure to biological characterization and individual exposure information, which is a key tool to evaluate the risk exposure to disease by biological alternation information. With the development of high throughput, broad spectrum and high efficiency screening and detection technology, biomonitoring is defined as traditional biological monitoring (targeted monitoring) and non targeted monitoring analysis (exposomic approaches). An exposomic approach differs from traditional biomonitoring in that it can theoretically include all exposures of potential health significance, whether they are derived from exogenous sources. Both traditional and nontraditional biomonitoring methods should be used to understand the complexity of exposures faced throughout the lifespan. Through hybrid approaches, emerging techniques and the integration of bioinformatics, and developing the detection methods for low abundance chemicals, improving the differentiation ability between endogenous and exogenous chemical, the health outcomes and exposures can be widely recognized and characterized, which can finally contribute to improving the precise prevention and intervention for diseases under the new exposomic model.
