Objective To explore the gender difference in clinical features and outcomes of elderly patients with coronary true bifurcation lesions after percutaneous coronary intervention (PCI).Methods A total of 169 consecutive patients were included in the study, who were diagnosed coronary true bifurcation lesions by coronary angiography (CAG)and received PCI in our hospital from December 2013 to December 2015.All patients were divided into 2 groups according to their gender (71 femals and 98 males).Angiographic characteristics of the coronary lesions and clinical data were analyzed in both groups.Clinical outcomes during follow up were recorded and studied.Results The levels of total cholesterol (TC), triglyceride (TG),high density lipoprotein cholesterol (HDL-C) and low density lipoprotein cholesterol (LDL-C) in the female group were significantly higher than in the male group (all P<0.05).The levels of BUN,Cr,UA,CyC and TBIL in the female group were significantly lower than in the male group (all P<0.05).Comorbidity rates of hypertension and diabetes were higher in female patients without significant differences (P>0.05).The median follow-up time was 17 months and the incidence rate of overall adverse events in women was higher than that of men (25.4% vs.11.2%, P<0.05).Conclusions The clinical outcomes of elderly patients with coronary true bifurcation lesions after PCI had gender differences.The rates of adverse events in female patients was found significantly higher than male patients.

OBJECTIVETo investigate the protective effect of ginsenoside Rg1 on oxygen-glucose deprivation (OGD) in PC-12 cells, and preliminarily discuss the potential molecular mechanism of mTOR/Akt/FoxO3 signaling pathway.

METHODThe OGD PC-12 cell model was established. The cell viability was measured by MTT assay. After the pretreatment with Rg1 with the concentration of 10, 20, 40 micromol x L(-1) for 24 h, the cell viability was observed. Lactate dehydrogenase (LDH) release, superoxide dismutase (SOD) ac- tivity and malondialdehyde (MDA) level were detected by colorimetry assay. mTOR, p-Akt(ser473), p-Akt(tjr308), Akt, p-FoxO3, FoxO3 in cytoplasm and nucleus, and total FoxO3 protein expression were detected by Western blot assay.

RESULTOGD could significantly in- hibit cell proliferation in 4-24 h in a time-dependent manner. After pretreatment for 24 h, Rg1 (20, 40 micromol x L(-1)) could notably elevate the cell viability and SOD viability and reduce the LDH release and MDA content. Besides, Rg1 also inhibited OGD-induced mTOR and p-Akt(ser473) decreases. After treatment for 6 h, OGD could reduce FoxO3 phosphorylation and promote FoxO3 in cytoplasm. This data suggested that Rg1 could protect PC-12 cell injury through mTOR/p-Akt/FoxO3 signaling pathway.

CONCLUSIONGinsenoside Rg1 could attenuate OGD-induced PC-12 cell injury. Its action mechanism may be closely related to activation of mTOR/p-Akt/FoxO3 signaling pathway.

BACKGROUNDOnabotulinumtoxinA is widely used in treating neurogenic detrusor overactivity (NDO). We carried out a systematic review and meta-analysis to assess the efficacy and safety of the drug for treating NDO.

METHODSWe searched the following databases: Medline, EMBASE, and the Cochrane Controlled Trials Register. All published randomized double-blind, placebo-controlled trials of onabotulinumtoxinA for the treatment of NDO were identified in the analysis. The reference lists of the retrieved studies were also investigated.

RESULTSFour publications involving a total of 807 patients were identified in the analysis, which compared onabotulinumtoxinA with placebo. The changes of the mean number of urinary incontinence per week (the standardized mean difference [SMD] = -10.91, 95% confidence intervals [CIs] = -14.18--7.63, P < 0.0001); maximum cystometric capacity (SMD = 146.09, 95% CI = 126.19-165.99, P < 0.0001) and maximum detrusor pressure (SMD = -32.65, 95% CI = -37.83--27.48, P < 0.0001) indicated that onabotulinumtoxinA was more effective than the placebo, despite the doses of onabotulinumtoxinA. Safety assessments primarily localized to the urinary tract indicated onabotulinumtoxinA were often associated with more complications. Urinary tract infections (relative risk [RR] =1.48, 95% CI = 1.20-1.81, P = 0.0002); hematuria (RR = 1.81, 95% CI = 1.00-3.24, P = 0.05) and urinary retention (RR = 5.87, 95% CI = 3.61-9.56, P < 0.0001).

CONCLUSIONSThis meta-analysis indicates that onabotulinumtoxinA to be an effective treatment for NDO with side effects primarily localized to urinary tract.

OBJECTIVETo study the correlation between Apnea Graph (AG) analysis of airway obstruction and cephalometric assessment of the posterior airway space in the diagnosis of obstructive level in patients with obstructive sleep apnea hypopnea syndrome (OSAHS), so as to improve the preoperative diagnostic accuracy and the therapeutic outcome.

METHODSThirty patients (28 males and two females) who were diagnosed with severe OSAHS (mean AHI 58.6) by overnight polysomnography in recent 3 months were enrolled. The ages of the patients ranged from 35 to 59 years old with the median age of 41.5 years old. The mean body mass index (BMI, x(-) ± s) was (28.8 ± 4.1) kg/m(2). Mean apnea-hypopnea index (AHI) was (58.6 ± 16.4)/h. The lowest oxygen saturation was averaged to 0.69 ± 0.09. All patients underwent AG study as well as cephalometric analysis preoperatively. A correlation analysis was performed between the percentage of lower level obstructions measured by AG and the posterior airway space (PAS) evaluated by cephalometric analysis.

RESULTSAll of the 30 patients had the obvious narrow PAS of 4.4 - 10.8 mm, with the average of (7.6 ± 2.1) mm. Their constituent ratios of lower level obstruction ranged from 2 to 87 percent with the median ratio of 15.5% [9.0%; 35.8%]. Among all the patients, only 2 cases had more than 50 percent obstruction of the airway at lower level, 8 cases had 30 to 40 percent obstruction, and 6 cases had the narrow PAS less than 6 mm. The constituent ratio of lower level obstructions had a negative rectilinear correlation with the data of PAS (r = -0.6511, P < 0.01), which meant the patient with a higher percentage of lower obstruction had the tendency to have a corresponding narrower PAS. Two cases whose constituent ratios of lower level obstructions were not compatible with the rectilinear tendency due to tonsillar hypertrophy were reported.

CONCLUSIONSAG analysis of airway obstruction and cephalometric assessment of the PAS could provide comparable and consistent results for the diagnosis of obstructive level in OSAHS. However, the tonsillar hypertrophy should be considered when using AG to identify the airway obstruction.

AIMTo study the effects of hydrocortisone sodium succinate on sodium current in human atrial myocytes and in guinea pig ventricular myocytes.

METHODSSingle cardiac myocytes were isolated by enzyme. The effects of hydrocortisone sodium succinate on sodium current (INa) were assessed by applying whole-cell patch clamp techniques.

RESULTSHydrocortisone sodium succinate (1, 3, 10 micromol x L(-1)) was shown to inhibit INa of both human atrial myocytes and guinea pig ventricular myocytes in concentration dependent manner and the IC50 were 6.97 and 8.74 micromol x L(-1), respectively. The inhibition effects acted quickly (1-3 min) and the maximal activating voltage of INa was not changed in both human and guinea pig cardiac myocytes.

CONCLUSIONHydrocortisone sodium succinate can exhibit inhibitory effects on INa in both human and guinea pig cardiac myocytes, and its inhibitory effects act rapidly, which are not consistent with genomic effects, so there may be nongenomic effects.

OBJECTIVETo discuss the surgical methods and effects in the treatment of sacrum tumor.

METHODSFifteen patients of sacrum tumor included 12 males 3 females aged from 17 to 68 years old,mean 54.6 years. Ten cases were primary tumor and 5 were metastatic tumor. Five cases underwent anterior approach tumor extirpation, 3 posterior approach tumor extirpation and 7 posterior tumor extirpation with bone graft and internal fixation of a pedicle screw and rod system. Additionally, all cases were treated with radiotherapy or/and chemotherapy post-operatively according to the character of the tumor.

RESULTSThirteen patients were followed-up for 4 months to 5 years. One patient had exacerbation accompanying dysfunction of urinary and feca after surgery, which relieved after four months of non-operative treatments. One chordoblastoma and 2 metastatic tumor died of recurrence and metastasis 1 to 2 years after operation, respectively. And in another case of giant cell tumor occurred the local recurrence 6 months after operation, who refused secondary surgical treatment.

CONCLUSIONIndividualized surgical treatment with conbination of radio therapy or/and chemotherapy will make good results for patients with sacrum tumor.

OBJECTIVETo explore the effects of total saponins of Rubus parviflolius (TSRP) on brain edema and blood brain barrier in rats.

METHODThe model of local cerebral ischemia was established in rats by reversible inserting a nylon thread into the anterior cerebral artery through the internal carotid artery brain hydrated amount and content change of Evan' s blue (EB) in cortex subjected to 2h middle cererbral artery occlusion (MACO) followed by 6 h, 24 h, 48 h, 72 h reperfusion and effect of TSRP. penetrability of blood brain-barrier (BBB) the index includes brain hydrated amount and penetrability of blood brain-barrier BBB.

RESULTCom- pared with I/R group. Both brain hydrated amount and the EB content decreased significantly in TSRP groups on the 6 h, 24 h, 48 h, 72 h of reperfusion after 2 hour of cerebral ischemia induced by MACO model.

CONCLUSIONTSRP could decrease brain hydrated amount and markedly lower permeability of blood-brain barrier subjected to 2 h MACO followed by 24 h reperfusion, and this may be a mechanism of TSRP alleviating brain edema during I/R.
