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.

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.

A full-length cDNA sequence encoding for the precursor of a venom peptide (named BmKCT) with homology to chlorotoxin has been isolated from a cDNA library made from the venom glands of the Chinese Scorpion Buthus martensii Karsch. The sequence of BmKCT is similar (68 % identities) to that of chlorotoxin isolated from Leiurus quinquestriatus quinquestriatus. To understand the biological function of BmKCT, this peptide was expressed using pGEX expression system and purified using GST affinity column and gel filtration.Whole cell patch-clamping recording showed that BmKCT could significantly inhibit chloride currents of gliomas cells, and the inhibitory effect was reversible. These results suggested that BmKCT might belong to the class of short chain toxins blocking the chloride ion channels.

Objective To investigate risk factors of the prognosis of patients with severe fever with thrombocytopenia syndrome (SFTS).Methods From May 2012 to July 2014,17 cases of severe fever with thrombocytopenia syndrome in Renmin Hospital of Wuhan University were treated.Clinical data including history of epidemiology,clinical manifestations,complications,physical examination and laboratory test results on admission and the third day after admission were retrospectively analyzed and compared with the death group and recovery group by application of Spearman correlation analysis.Results Elderly male patients with neuropsychiatric symptoms,or abnormal liver function,or abnormal blood clotting function had higher risk of the poor prognosis.In SFTS patients,AST,ALT was significantly increased,AST 539 U/L (229.73,545.4) U/L (r =0.597,P =0.015) was a risk factor affecting prognosis.Elevated blood ammonia indicated serious liver dysfunction and neurological dysfunction which were manifested as irritability,delirium,and trembling limbs.In SFTS patients,platelets were significantly decreased accompanied with mouth ulcers / bleeding gums,gastrointestinal bleeding.PLT 24.88 × 10 9/L-1 (12.75,35.00) ×10 9/L-1 (r=0.557,P=0.005) or APTT 86.06 s (66.88,114.18) (r=0.798,P=0.001) or D-dimmer 9.79 mg / L (4.09,16.51) mg/L (r =0.597,P =0.015) are risk factors affecting poor prognosis.Conclusions On the third days after admission,AST,WBC,PLT,APTT,Ddimmer are risk factors for prognosis of patients with severe fever with thrombocytopenia syndrome infected by a novel bunyavirus.

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.

OBJECTIVETo investigate the role of endogenous hydrogen sulfide (H2S) in erectile dysfunction (ED) induced by androgen deficiency.

METHODSWe randomly divided 30 eight-week-old healthy male SD rats into six groups: 2-week control (A), 4-week control (B), 2-week castration (C), 4-week castration (D), 2-week castration + androgen replacement (E), and 4-week castration + androgen replacement (F), those in groups E and F subcutaneously injected with testosterone propionate (TP) at the physiological dose of 3 mg/kg per day after castration, while those in the other groups with isodose oil instead. At 2 and 4 weeks after operation, we determined the level of serum testosterone (T) , intracavernous pressure (ICP) , mean carotid arterial pressure (MAP) of the rats, measured the concentration of H2S in the plasma and corpus cavernosum tissue, and detected the expressions of cystathionine-P3-synthase (CBS) and cystathionine-gamma-lyase (CSE) by immunohistochemistry and Western blot.

RESULTSThe serum T level was significantly lower in group C ([0.63 +/- 0.15] nmol/L) than in A ( [ 16.55 +/- 4.17] nmol/L) and E ( [ 18.99 +/- 4.62] nmol/L) (P <0.05), as well as in group D ([0.70 +/-0.22] nmol/L) than in B ([15.44 +/-5.18] nmol/L) and F ([20.99 +/-6.41] nmol/L) (P <0. 05) , and so were ICP/MAP after 5 and 7 V electrical stimulation of the pelvic ganglia (P <0. 05) , H2 S concentration (P <0.05), and the expressions of CBS and CSE (P <0.05). The expressions of CBS and CSE proteins were also significantly decreased in group C as compared with D (P <0.05).

CONCLUSIONThe reduced expressions of CBS and CSE may inhibit the H2 S signaling pathway, which might be one of the mechanisms underlying androgen deficiency-induced ED in rats.
