AIMTo investigate the effects of CoQlo supplementation on liver mitochondrial function and aerobic capacity in adolescent athletes.

METHODSBased on a single blinded study design, 18 male adolescent swimming athletes were randomized into two groups, supplement CoQ10 100 mg/d (Q group), or placebo (P group) for 28 days respectively.

RESULTS(1) After supplementation, the plasma CoQ10 concentration in Q group was significantly elevated and significantly higher compared to P group. (2) After supplementation, the rest plasma MDA level in Q group remained unchanged and was significantly lower compared to P group. (3) The plasma CoQ10 concentration of the 18 athletes was significantly decreased during the first constant endurance exercise. (4) The baseline plasma CoQ10 of the 18 subjects showed significantly positive correlation with VO2max measured in the first incremental exercise. (5) No significant difference of increased level of AKBR between Q group and P group. (6) No significant difference of increase level of VO2max, individual lactate threshold and exercise economy between Q and P group.

CONCLUSIONAlthough there is an increased demand for plasma CoQ10 during endurance exercise and CoQ10 supplement can depress lipid peroxidation, there is no effect of CoQ10 supplementation on liver mitochondrial function and aerobic capacity in adolescent athletes.

OBJECTIVETo investigate the significance of human papillomavirus test in triage of patients with atypical squamous cell of undetermined significance (ASCUS) diagnosed by cervical cytology.

METHODSHuman papillomavirus test,colposcope and cervical biopsy were performed in 184 patients with a referral diagnosis of ASCUS by cervical cytology.

RESULTSConfirmed by pathological diagnosis of cervical biopsy, 112 cases were chronic inflammation (60.87%), 33 CIN I (17.93%), 17 CIN II (9.24%), 8 CIN III (4.35%), 4 cervical squamous carcinoma (2.17%) and 10 condyloma (5.43%). Of the 184 women with cytological ASCUS, 124 (67.39%) cases were positive in high-risk HPV test among which 66 cases were histologically confirmed as chronic inflammation (53.23%), 22 as CIN I (17.74%), 16 as CIN II (12.90%), 8 as CIN III (6.45%), 4 as cervical squamous carcinoma (3.23%) and 8 as condyloma (6.45%). The positive rate of HPV in groups of ASCUS were higher than those with negative HPV (P < 0.003).

CONCLUSIONWomen with ASCUS should be tested for HPV. Cervical biopsy under colposcopy is recommended for women with HR-HPV infection.

OBJECTIVETo research the bacteriostatic effects of Qingkailing Injection Extract (QKLIE) and combination therapy of Qingkailing Injection (QKLI) and antibiotics on bacteria carrying New Delhi metallo-3-lactamase 1 (NDM-1) blaNDM-1 resistance gene, and to determine their minimal inhibitory concentrations (MIC).

METHODSThe antimicrobial experiments of QKLIE (Radix Isatidis, baicalin, gardenia, honeysuckle) and combination therapy of QKLI and antibiotics were performed by using the agar dilution method and K-B method. The MIC was determined from each extract.

RESULTSThere were different degrees of inhibitory effects on resistant bacteria carrying blaNDM-1 by extracts from main components of QKLI. Of them, the inhibitory effect of baicalin was the best and the MIC of the resistant bacteria was 0.015 g/mL to WD, 0.020 g/mL to WX, 0. 005 g/mL to WJ, and more than 0.020 g/mL to pGEX-4T-NDM-1/DH5alpha (GST-NDM-1), respectively. The MIC value of each extract was sequenced from high to low as baicalin, honeysuckle, gardenia, and Radix Isatidis. Furthermore, combination therapy of QKLI and antibiotics greatly enhanced the antimicrobial activity of each antibiotics when used alone, showing very obvious antibacterial effects on multidrug resistant bacteria carrying blaNDM-1 gene. Of them, the optimal effects were obtained when combined with penicillins (penicillin G, mezlocillin, piperacillin/ tazobactam, ampicillin/sulbactam), with the antibacterial effects improved by 10 folds. The antibacterial effects of other kinds of antibiotics were improved to some extent. Conclusions QKLIE and combination therapy of QKLI and antibiotics showed better bacteriostatic effects on resistant bacteria carrying blaNDM-1 gene. This study provided theoretical bases for drug development, medication and treatment for super-resistant bacteria carrying blaNDM-1.
