Objective To study the effects of hydrogen dioxide (oxygen free radical donator) and vitamin C (oxygen free radical scavenger) on the electric current of large conductance calcium -activated potassium channels (BKCa channels) in isolated outer hair cells in aging guinea pigs .Methods Acute enzyme was used to isolat outer hair cells of aging guinea pigs ,in which of BKCa channel's electric current was observed and recorded by whole-cell recording mode of patch -clamp .After recording the stable and normal electric current of BKCa channels ,added H2 O2 dilution (0 .2 mmol/L) 40 μl in the 2 ml chambers within freshly isolated outer hair cells so that the concen‐tration of H2 O2 in the balneum would be 4 μmol /L .The groups(n=5) received individually vitamin C solution (5 mg/ml) 0 ,10 ,20 ,40μl in the 2 ml chambers within freshly isolated outer hair cells so that the concentration of vi‐tamin C in the balneum would be 0 ,25 ,50 ,100 μg /ml ,observing and recording the effects of different concentration of vitamin C to electric current of BKCa channels .Results ①In the w hole-cell mode of patch -clamp ,the rapid activation and non-deactivation electric current with a string of large amplitude was recorded ,above -40~ -30 mV activation voltage .The electric current increased with the increasing membrane potential .The amplitude in‐creased continuously and performed characteristics of outward rectification .When the concentration of IbTX was 100 nmol /L ,the activity of the channel was completely blocked and confirmed BKCa channel's electric current .②Medication within three minutes ,when VT was +50 mV ,the BKCa channels'the maximum peak current densities of 4 μmol /L H2 O2 group rose from 22 .09 ± 0 .27 PA /PF to 43 .53 ± 1 .09 PA/PF ,amplification was 97 .06% .In H2 O2 4 μmol /L + vitamin C with different concentrations as 25 ,50 ,100 μg/ml groups ,the BKCa channels'elec‐tric current performed about concentration-dependent inhibition ,and electric current's amplitude and peak current density decreased with the increasing concentration of vitamin C ,the I-V curves were reduced .However ,this still could not be recovered to the normal levels .Conclusion The oxygen free radical /BKCa exists in the process .The vitamin C as oxygen free radical scavenger can reverse the process to a large extent .

[Abstract ] Objective The tension-free vaginal tape is the main method for treatment of stress urinary incontinence (SUI). The aim of the present study was to analyze the effect and safety of tension-free vaginal tape ( TVT) and tension-free vaginal tape-obtu-rater ( TVT-O) for female stress urinary incontinence and to sum up the experiences . Methods Clinical data of 142 patients who re-ceived anti-incontinence surgery ( TVT/TVT-O ) between January 2011 and May 2014 were retrospectively analyzed , 111 cases re-ceived TVT and 31 cases received TVT-O.The effect and the complication were analyzed at least 6 months post surgery .Incontinence quality of life ( I-QOL) and organ prolapse/urinary incontinence sexual function questionnaire ( P-ISQ) were used to observe the sub-jective symptoms .One hour pad test value was used to assesse the objective response . Results The effective rate post-TVT/TVT-O was 88.03%, and the cure rate was 95.07%6 months post surgery.In the group of TVT, I-QOL and P-ISQ score were 52.1 ±16.8 and 60.1 ±36.5 at time of pre-operation, and they were 92.1 ±17.1 and 62.2 ±37.8 at time of post-operation, respectively.In the group of TVT-O, they were 61.2 ±15.8 and 57.1 ±36.8 at time of pre-operation, and they were 91.3 ±20.1 and 62.1 ±35.9 at time of post-operation, respectively.Compared with pre-operation, I-QOL and P-ISQ score were obviously rised at time of post-operation ( P<0.05 ). The total incidence rate of surgery complication was 21.83%.And,in proper was urinary tract infection (16.9%),OAB (14.08%), bladder injury(11.26%), retention of urine(7.74%), nerve pain(2.81%), retropubic hematoma(1.41%), urethral injury(1.41%).All patients′surgeries were successful except three cases.One patient was cured after reoperation .The other two was improved with dislodge sling urinary incontinence . Conclusion TVT/TVT-O was a highly effective and safe method in the treatment of SUI .But we should not ignore the complications;the timely and effective treatment measures could improve the operation rate of success .

Objective:To observe the clinical efficacy of warm needling moxibustion plus tuina in treating knee osteoarthritis (KOA) due to cold-dampness blocking collaterals.
Methods:Forty-eight KOA patients were randomized into 2 groups by their visiting sequence, 24 cases in each group. The treatment group was intervened by warm needling moxibustion plus tuina, while the control group was treated with acupuncture plus tuina. The two groups were both treated once a day, 30 min for each session, 10 d as a treatment course, totally for 3 treatment courses. The visual analogue scale (VAS) and Lysholm knee scoring scale (LKSS) were observed before and after the treatment to evaluate the clinical efficacy.
Results:After 3 treatment courses, the VAS and LKSS scores were significantly changed in the two groups (P<0.01), and the between-group differences were also statistically significant (P<0.01). The markedly-effective rate was 83.3% in the treatment group versus 66.7% in the control group, and the difference was statistically significant (P<0.05).
Conclusion:Warm needling moxibustion plus tuina can produce a more significant efficacy than acupuncture plus tuina in treating KOA due to cold-dampness blocking collaterals.

OBJECTIVETo study the effect of Qinghuang Powder (QHP) combined Chinese herbs for Pi-strengthening and Shen-reinforcing (CHPSSR) on hypoxia-inducible factor 1alpha (HIF-1alpha) in bone marrow mononuclear cells of myelodysplastic syndrome (MDS) patients.
METHODSChanges of HIF-1alpha in bone marrow mononuclear cells of MDS patients were detected in 25 MDS patients treated by QHP combined CHPSSR using flow cytometry. Meanwhile, 13 healthy subjects were recruited as the control group. Changes HIF-1alpha levels in various serial bone marrow mononuclear cells were detected.
RESULTS(1) Among the 25 patients in the treatment group, there were 19 patients effective and 6 patients ineffective, with the total effective rate being 76%. (2) Compared with before treatment, levels of peripheral blood WBC, Hb, PLT, and ANC significantly increased in the treatment group after treatment, showing statistical difference (P < 0.05, P < 0.01). (3) Compared with before treatment, the HIF-1alpha mean fluorescence intensity was enhanced in bone marrow lymphocytes, monocytes, granulocytes, and nucleated red blood cells of the treatment group after treatment (P < 0.05, P < 0.01). Compared with the control group, the HIF-1alpha mean fluorescence intensity was weakened in bone marrow lymphocytes, monocytes, and nucleated red blood cells of the treatment group before treatment; while it was obviously enhanced in granulocytes (P < 0.01). But after treatment the HIF-1alpha mean fluorescence intensity increased more in the granulocytes of the treatment group than in those of the control group (P < 0.01), but there was no statistical difference in bone marrow lymphocytes, monocytes, or nucleated red blood cells.
CONCLUSIONQHP combined CHPSSR could improve HIF-1alpha levels in bone marrow lymphocytes, monocytes, granulocytes, and nucleated red blood cells of MDS patients, thus improving Hb levels of MDS patients, and improving their anemia and correlated symptoms.
