OBJECTIVE:
This study conduct a qualitative synthesis and quantitative meta-analysis of VFAFI, aimed to study whether it is a useful treatment for UVCP.
METHOD:
Electronic databases PubMed, YZ365. COM, WANFANG DATA, CMJD, CHKD,CNKI were searched using relevant keywords. Reported treatment outcomes were clustered into three categories,i. e. subjective, perceptual,acoustic,aerodynamic,and stroboscopic. Meta-analyses were performed on studies with numerical results using random effects model.
RESULT:
Five articles were identified with a total of 404 patients. All the studies reported significant improvements or decrease after VFAFI in each category of outcome measurements. Meta-analysis demonstrated a significant increase or decrease in all categories. Adverse effects include slight inflammatory reponse can resolve spontaneously within 1 month. The recurrence rate after VFAFI was high due to the self absorption. NNE and Jitter of post-operation is lower than pre-operation,there is no significantly change between the control group and experimental group; F0, Shimmer and MPT of post-operation is higher than pre-operation, there is no significantly change between the control group and experimental group.
CONCLUSION
The invasiveness and morbidity of VFAFI are low and the side effects are self-limited. Meta-analyses demonstrated significant improvements or decreased from both objective and subjective measurements. Further controlled studies with longer follow-up periods and more person were included may evaluate the effectiveness of VFAFI more reliably.

Objective To investigate the effects of sevoflurane postconditioning on cardiomyocyte apoptosis during myocardial ischemia-repeffusion (I/R) in rats.Methods Forty-five healthy male Wistar rats weighing 250-280 g were randomly divided into 3 groups ( n =15 each):group sham operation ( group S) ; group I/R and group sevoflurane postconditioning (group Spo).The animals were anesthetized with intraperitoneal 3% pentobarbital 45 mg/kg,tracheally intubated and mechanically ventilated.Myocardial I/R was produced by occlusion of anterior descending branch of left coronary artery for 30 min followed by 120 min reperfusion in groups I/R and Spo.In group Spo the animals inhaled 2.5% sevoflurane for 5 min starting from 1 min before reperfusion was started.The animals were sacrificed at the end of 120 min reperfusion.Their hearts were removed for measurement of infarct size and the area at risk and determination of apoptotic index (the number of apoptotic cells/the total number of cells) and Bcl-2 and Bax protein and mRNA expression.Results Sevoflurane postconditioning significantly reduced infarct size in group Spo as compared with group I/R.There was no significant difference in area at risk between groups I/R and Spo.Myocardial I/R significantly increased the apoptotic index,Bcl-2 and Bax protein and mRNA expression in group I/R as compared with group S.Sevoflurane postconditioning significantly decreased apoptotic index and Bax protein and mRNA expression but increased Bcl-2 protein and mRNA expression in group Spo as compared with group I/R.Conclusion Sevoflurane postconditioning attenuates myocardial I/R injury by redncing myocardial apoptosis,up-regulating Bcl-2 expression and down-regulating Bax expression.

ObjectiveTo investigate the effect and mechanism of prostaglandin E2 (PGE2) in renin regulation at the juxtaglomerular apparatus (JGA). MethodsMacula densa cell line (MMDD1) was cultured on the special filter. In the medium on the apical lateral of the cells, low concentration of sodium chloride, chloride and different doses of angiotensin Ⅱ (Ang Ⅱ) were used to stimulate the PGE2 secretion. The PGE2 concentration was tested by ELISA. In the animal experiment, the response of plasma renin activity (PRA) to acute intraperitoneal administration of captopril (30 mg/kg) was determined, in conscious wild-type (WT) and cyclooxygenase COX-2-/- mice on C57BL/6 genetic backgrounds. PRA was measured in plasma obtained by tail vein puncture. Different concentrations of PGE2 were used to stimulate the renin secretion of primary cultured JGA cells from COX-2-/- mice and wild type mice. In specific Gsα gene delete mice (low renin producing mice), 24 h urine was collected to test the concentration of PGE2. The COX-2 mRNA and protein of the kidney cortex were observed by real-time PCR and immunohistochemicul staining. ResultsLow chloride could stimulate the PGE2 secretion both at the apical and basement of the macula densa cells. In COX-2-/- mice, the base PRA and were obviously lower than wild type mice. Captopril could stimulate the PRA of (COX)-2-/- mice increasing 32.8 times. But Ang Ⅱ had no effect on PGE2 secretion in macula densa cells. In primary cultured JGA cells, the decreasing renin seretion was partly recovered by PGE2 in cells from COX-2-/- mice. In low renin producing mice, the expression of COX-2 mRNA in the kidney cortex increased by (8.07±1.08) times (n=6, P=0.0022). The COX-2 protein of the kidney cortex and the urine PGE2 increased by several times. ConclusionsLow chloride is the primary stimulation messenger of PGE2 secretion in macula densa cells. The PRA in COX-2-/- mice can be stimulated by angiotensin converting enzyme inhibitor, but the Ang Ⅱ has no direct effect on macula densa cells. When renin production is abolished in JGA cells (Gsα delete mice), COX-2 mRNA and protein up-regulation is observed in kidney cortex and macula densa. PGE2 plays an important role in regulation of renin secretion and renin release in JGA by precise feedback mechanism.
