Follow-up loss with a subsequently forgotten stent for more than 12 mo occurred in 38 patients. We retrospectively examined the cause of biliary stent insertion, status of stents, complications associated with biliary stents and management outcomes of long-term plastic biliary stents. Continuous variables were analyzed using the t test. Observed frequencies in subsets of the study population were compared using Fisher’s exact test and χ<sup>2</sup> tests. Statistical significance was defined as P < 0.05 (two-tailed).RESULTSMean age of patients was 73.7 ± 12 years and male-to-female ratio was 2.2:1. Indications of plastic biliary stent insertion were bile duct stones (63.2%, 24/38) and benign bile duct stricture (52.6%, 20/38). Mean duration of retained plastic stent was 22.6 ± 12.2 mo, and in 10 cases (26.3%), stents were retained for more than 24 mo. Common bile duct (CBD) stones or sludge were found in most cases (92.1%, 35/38). The most common complication was acute cholangitis (94.7%, 36/38). Stent removal by endoscopic approach was successfully performed in 92.1% (35/38) of the cases. In 3 cases, an additional plastic stent was inserted alongside the previous stent due to failure of the stent removal. Endoscopic removal of bile duct stones was successful in 73.7% (28/38) of the cases. When patients were divided into two groups by duration of stent placement (12 to 24 mo vs over 24 mo), there were no differences in the development of cholangitis, presence of biliary stones, and success rate of endoscopic removal of stones and biliary stents.CONCLUSIONThe most common complication of retained long-term plastic biliary stents was acute cholangitis associated with CBD stones. Endoscopic management was successfully performed in m展开更多

The equivalence between the RBFN and the estimate of Parzen window probabilistic density is proved. It is pointed out that the I/O functions in RBFN hidden units can be generalized to general Parzen window probabilistic kernel function or potential function, too. This paper discusses the effects of the shape parameter a in the RBFN and the forgotten factor A in RLSA on the results of the recognition of three kinds of kernel function such as Gaussian, triangle, double-exponential, at the same time, also discusses the relationship between A and the training time in the RBFN.展开更多

Since then, Chinese scholars have analyzed the necessity and feasibility and also the possible ways in which the right to be forgotten might be safeguarded. However, the argument of the right to be forgotten and its path deserve to be further discussed. The right to be forgotten is not a solution to the violation of personal information in China because our domestic systems and practices have allowed individuals to delete online information and the construction of the forgotten right with the right of personal information as the core may hinder the development of the Internet. This article suggests that the introduction of the right to be forgotten should follow China’s national conditions and should be constructed with privacy as the core in the system design, and the content should further clarify personal data. The subjects of data should be differentiated in specific implementation and the scope of application should encompass the criminal field.展开更多

All TKAs were cemented and cruciate retaining. The mean follow-up period was 3.2(2 to 4) years. All the patients had symptomatic and debilitating unilateral or bilateral osteoarthritis for which all conservative and non-surgical treatments were failed, thus preoperatively the patients had poor functionality. All patients were asked to complete Forgotten Joint Score(FJS) and Oxford Knee Score(OKS) questionnaires. The patients were matched according to age, gender, year of surgery, Kellgren-Lawrence score and pre- andpostoperative overall knee alignment. The FJS and OKS questionnaire results of the two groups were then compared. RESULTS: A mixed-effects model was used to analyze differences between SBTKA and UTKA. OKS: The mean difference in the OKS between the patients who had undergone SBTKA and those who had undergone UTKA was 1.5, which was not statistically significant(CI =-0.9:4.0, P-value = 0.228). The mean OKS of the SBTKA patients was 37.6(SD = 9.0), and the mean OKS of the UTKA patients was 36.1(SD = 9.9). FJS: The mean difference in the FJS between the patients who had undergone SBTKA and those who had undergone UTKA was 2.3, which was not statistically significant(CI =-6.2:10.8, P-value = 0.593). The mean FJS of the SBTKA patients was 59.9(SD = 27.5), and the mean FJS of the UTKA patients was 57.5(SD = 28.8). CONCLUSION: SBTKA and UTKA patients exhibited similar joint functionality and knee awareness. Our results support the use of SBTKA in selected patients suffering from clinically symptomatic bilateral osteoarthritis.展开更多

Among them, dental caries continues to be the single most prevalent and costly oral infectious disease （Marsh, 2003; Dye et al., 2007）. Dental caries results from the interaction of specific bacteria with constituents of the diet within a dental biofilm known as plaque （Bowen, 2002）. Sucrose is considered to be the ＂arch criminal＂ from the dietary aspect because it serves as a substrate for synthesis of extracellular （EPS） and intracellular （IPS） polysaccharides in dental biofilm and is also fermentable （Bowen, 2002）.展开更多

While academicsfrom the UK and the US are wary of the right to be forgotten, their Chinese counterparts are fairly optimistic thatthis right can be transplanted to China. It is found that remarks such as “introducing the right to be forgotten”,“establishing personal information rights”, and “laying down a law on personal information rights” can befrequently observed in relevant studies published in recent years. As an immature new right that has been writteninto laws of some countries, whether the right to be forgotten is in line with China’s practicalities should becogitated on before it is enshrined in law. Having analyzed what influences the right to be forgotten will exert onChina’s rule of law and economic development if it is included in China’s legal system, a conclusion has beenreached. First, the right to be forgotten is detrimental to Chins’ s advancement of rule of law because it contradictsrights such as freedom of the press, freedom of speech and right to know. Second, it will also inhibit thedevelopment of China’s burgeoning digital economy. Therefore, the right to be forgotten should not be introducedto or even established in Chinese law at this stage.展开更多
