A novel electrochemiluminescence ( ECL) method for the determination of L-cysteine ( L-Cys) was established. water-soluble CdS quantum dots ( QDs) with Cd2+rich surface were synthesized via a controllable one-poe approach. The mercapto group in L-cysteine molecule can specifically interact with excessive Cd2+on the surface of CdS QDs, resulting in enhancement of ECL intensity of the CdS QDs, which can be used for the detection of L-Cys. Under the optimal experimental conditions, the enhancement of ECL intensity was linear with the concentration of L-Cys in the range of 5. 0×10-9-1. 0×10-5 mol/L. The limit detection of (S/N=3) was 1. 2×10-9 mol/L. In comparison with other methods for detecting L-Cys, this method is more simple and selective, and can be applied to detect L-Cys in real sample with satisfactory results.

Objective:To retrieve and analyze the relevant literatures on vancomycin added into bone cement to provide the evi-dence for the treatment of osteomyelitis and other orthopedic infections. Methods:Search strategy and criteria of inclusion and exclu-sion for literatures were designed. PubMed, SCI, Embase, CNKI, VIP and the other databases were searched, and the articles from the establishment date to February 2014 were statistically analyzed using bibliometric methods. The final included documents were sta-tistically analyzed in respect of the article type, year, contents, citation frequency and the maln contents of the study. Results:A total of 1 941 articles were searched, and 430 of them were in the final inclusion. The total number of the articles in every year was in an es-calating trend. The paper focused on the research and analysis of clinical studies, and there were 74 clinical studies among the includ-ed literatures, which accounted for 17. 2% of all the included literatures. The highest citation frequency was 97 for one literature. The research included the overall situation, year distribution, publishing country, research type analysis, corresponding author and their in-stitutions, journals, citation frequency, and the maln content of work and clinical studies on vancomycin added into bone cement. The analysis could provide reference for the clinical treatment of orthopedic diseases. Conclusion: The results of the analysis show that vancomycin added into bone cement in the treatment of chronic osteomyelitis is effective with high security, and the technology is ma-ture.

BACKGROUND:Proximal humeral internal locking system fixation for complex humeral fractures via deltoid splitting approach provides good clinical results, but certain complications stil existed.
OBJECTIVE:To explore the postoperative complications and the related risk factors for displaced three-part and four-part fractures of proximal humerus treated with proximal humeral internal locking system fixation via deltoid-splitting approach, and to propose the corresponding countermeasures.
METHODS:106 cases with displaced three-part and four-part fractures of proximal humerus were retrospectively analyzed. The relationship between postoperative complications and the related risk factors was analyzed with Logistic regression analysis.
RESULTS AND CONCLUSION:A total of 81 patients were fol owed-up for 12 to 30 months. The mean Constant score at 12 months after operation was (76.57±4.70) points. The postoperative complications occurred in 31 patients (38.3%) of which impingement syndrome involved in 16 cases (19.8%), head-shaft angle loss in six cases (7.4%), head-shaft angle loss combined with screws cut-out in two cases (2.5%), pure screws cut-out in two cases (2.5%), humeral head necrosis in two cases (2.5%), fat liquefaction in five cases (6.2%). Single factor analysis showed that there were significant differences in the superiorly located greater tuberosity, superiorly located plate and Neer classification between impingement group and un-impinged group (P<0.05). There were statistical y significant differences in age, postoperative medial cortical defects and Neer classification between head-shaft angle loss group and un-loss group (P<0.05). By means of logistic regression analysis, the superiorly located greater tuberosity, superiorly located plate and Neer classification were the individual predictors for postoperative impingement syndrome;postoperative medial cortical defect and Neer classification were the individual predictors for postoperative head-shaft angle loss.

Objective To explore the value of peripheral blood serum levels of PCT,CRP,TNF-α and free DNA of cells in predicting the development of MODS in patients with multiple trauma.Methods Complete detail clinical data of 54 casualties with multiple trauma admitted within 24 hours after accident from January 2011 through January 2012 were collected for retrospective study.The patients were divided into MODS group and non-MODS group according the criteria set forth by the Chinese Society of Critical Care and Emergency Medicine in 1995 national conference.The data of two groups are comparable,and data of another 20 healthy subjects undertaking routine annual physical examination were taken as control.The peripheral blood levels of PCT,CRP,TNF-α and free DNA of patients of two groups were determined 1 d,2 d,3 d,and 5 days after admission.Then the results were analyzed and compared between groups.Results Compared with non MODS group,the levels of PCT,CRP,free DNA of cells in MODS group were significantly higher (P ＜ 0.05),but there was no deference in TNF-α between MODS group and non-MODS group (P ＞ 0.05).When the relative risks of increased PCT (PCT≥6 mg/L),increased CRP (CRP≥ 130 mg/L)、and increased free DNA of cells (free DNA ≥ 10 0005/L) were analyzed,the presence of these 3 biomarkers with high levels occurred at the same time was the most accurate way to predicts MODS in 6.00 relative risk (RR),and the positive predictive value was 100％.Conclusions PCT,CRP,free DNA of cells could be the predictors of MODS in patients with severe multiple trauma,and the presence of high levels of these three biomarkers appearing together had high sensitivity and specificity for prediction.

AIM: To investigate the effect of retinoic acid on proliferation of renal interstitial myofibroblasts in a rat model of the left unilateral ureteal obstruction (UUO). METHODS: UUO model was established by unilateral ligation of ureter in 36 SD rats. Rats were divided into 2 groups: Retinoic acid-treated group and control group, each with 18 rats. UUO rats were treated with either daily subcutaneous injection of 10 mg/kg body weight of all trans-retinoic acid or vehicle alone two days before the operation until being sacrificed. Groups of 6 rats were killed on day 3, 7 and 12 after ligation of the left ureter. The percentage of renal tubular lesion, interstitial fibrosis score, the number of interstitial myofibroblasts, the number of proliferating myofibroblasts and the expression of TGF?-1 mRNA were determined. RESULTS: There were significant accumulation and local proliferation of myofibroblasts in the interstitium of the UUO rats. On day 7 of the UUO model, the percentage of tubular lesions and interstitial fibrosis score were significantly lower in the retinoic acid-treated group than those in control group [(15.9?2.0)% vs (27.3?2.2)% and (0.47?0.12) vs (1.65?0.18), P

Objective To investigate the nutrition status of the focus groups of iodine deficiency in the 5 coastal counties(districts)in Guangxi in 2008 to propose corresponding prevention and control measures.Methods In the 5 coastal counties(districts)in Guangxi,including Haicheng,Tieshangang,Yinhai districts and Hepu county in Beihai city,Qinnan district in Qinzhou city,the rates of iodized salt coverage,qualified iodized salt and consumption of qualified iodized salt had always been below the average level of Guangxi.In the study,6 towns were randomly picked in Hepu district,and 3 towns were randomly picked in each of the other 4 coastal counties(districts).Two administrative viRages were randomly picked in each town.Forty children ages 8 to 10 and 10 women of child-beating age from 18 to 42 which included 5 pregnant and lactating women,were picked from each administrative village.Arsenic-cerium catalyzed spectrophotometry(WS/T 107-2006)Was used to determine the urinary iodine.Results In total,1437 urine samples of the children Were picked.The median of the children's urinary iodine Was 191.0μg/L,with 1.4%(20/1437)of the children's urinary iodine<20 μg/L,and 5.4%(77/1437)<50 μg/L, and 20.3%(292/1437) < 100 μg/L. The medians of the children's urinary iodine were 134.5 - 220.0 μg/L.In Haicheng and Hepu, the medians of the children's urinary iodine were higher than 200 μg/L(220.0,209.5 μg/L, respectively). The medians of the children's urinary iodine in the other 3 counties(districts) were within the suitable range between 100 and 200 μg/L(134.5,162.4,199.3 μg/L, respectively). The medians of the 8- and 9-year-old ehildren's urinary iodine (192.3,206.7 μg/L, respectively) were higher than that of the 10-year-old children's(157.2 μg/L, χ2 = 19.644,41.997, all P < 0.017). Totally, 365 urine samples of the women were picked.The medians of the women's urinary iodine in the 5 counties were 88.2 - 195.6 μg/L, with 195.6 μg/L in Haicheng and 156.5 μg/L in Hepu, and 88.2 μg/L in Tieshangang, which was the lowest and below 100 μg/L. The median of the childbearing-age women's urinary iodine was the highest(152.6 μg/L). The median of the lactating women's urinary iodine was the second (131.9 μg/L). The median of the pregnant women's urinary iodine was the lowest (89.4 μg/L) and below 100 μg/L. Only 6.7%(2/30) of the pregnant women's urinary iodine were within the suitable range between 150 and 250 μg,/L. Conclusions In the 5 coastal counties(districts) in Guangxi, 8 to 10-year-old children had good nutrition levels while childbearing-age and lactating women were within the suitable range. As a whole, the pregnant women had insufficient iodine nutrition. We propose that the iodine nutritional status of pregnant women is monitored routinely, with further prevention, control measures, health publicity and education necessary to improve iodized salt coverage.
