Objective: To observe the clinical efficacy of thunder-fire moxibustion for hypomenorrhea after induced abortion. Methods: A total of 74 patients with hypomenorrhea after induced abortion were randomized into two groups, with 37 cases in each group. The control group was treated with conventional hormone sequential therapy, and the observation group was treated with thunder-fire moxibustion. The course of treatment was 3 menstrual cycles. The traditional Chinese medicine (TCM) symptom scores, menstrual volume, endometrial thickness and the sex hormone levels were observed before and after treatment. The clinical efficacy was compared after treatment. Results: The total effective rate in the observation group and the control group was 91.4％ and 73.5％, respectively, and the difference between the two groups was statistically significant (P<0.05). After treatment, the TCM symptom scores in both groups decreased significantly (all P<0.05), and the scores in the observation group were lower than those in the control group (P<0.05). The menstrual volume, endometrial thickness and each sex hormone level of the patients in both groups were significantly improved after treatment (all P<0.05), and the improvements in the observation group were more significant than those in the control group (all P<0.05). Conclusion: Thunder-fire moxibustion can significantly improve the clinical symptoms of patients with hypomenorrhea after induced abortion; it can increase menstrual volume and endometrial thickness, and regulate the sex hormone levels, producing a better curative effect than the conventional hormone sequential therapy.

Background Surgical induced astigmatism induced by a 5.5mm of superior scleral tunnel incision is a key cause of influencing vision outcome in the high myopic eyes after implantation of Artisan phakic intraocular lens(IOL).Objective This study was to evaluate the surgical induced astigmatism through a 5.5mm superior scleral tunnel incision during the implantation of Artisan phakic IOL.Methods This was a case observational study.The clinical data of 202 eyes of 111 patients with Artisan IOL implantation for high myopia from October 2004 through October 2008 was collected.The patients were followed-up for 12 months.The uncorrected visual acuity(UCVA),best spectacle-corrected visual acuity(BCVA),spherical equivalent(SE),cylinder equivalent(CE) and cylinder axis were examined before surgery and postoperative 1,3,6,12 months.The patients were divided into with rule group and against rule group according to the cylinder axis.Surgery-induced astigmatism value was calculated using Holladay vector analysis formula.This clinical trial was approved by the Ethics Committee of Guangdong General Hospital.Written informed consent was obtained from each patient prior to the surgery.Results The UCVA of 195 eyes(94.1%) was 0.5 or better in postoperative 12 months,and that of 172 eyes(85.1%) showed the improvement of BCVA during the follow-up duration.The mean CE values were reduced in 1,3,6,12 months after surgery in comparison with before surgery(t=-4.30,P=0.00;t=-2.27,P=0.01;t=-2.04,P=0.04;t=-2.79,P=0.01).Vector analysis of total surgically induced astigmatism revealed that the mean incision-induced astigmatism value was +1.94D,+2.26D,+2.29D,+2.25D at 171°,170°,181°,175° in 1,3,6,12 months after surgery.The surgery-induced astigmatism was(+1.97±1.84)D,(+2.25±1.75)D,(+2.27±1.76)D,(+2.24±1.75)D in with rule group at postoperative 1,3,6,12 months respectively;while those in against rule group was(+1.75±1.88)D,(+2.35±1.74)D,(+2.38±1.76)D,(+2.34±1.74)D respectively.No significant differences were found between the two groups(t=0.54,-0.29,-0.27,-0.29;P=0.59,0.78,0.79,0.78).Conclusion Implantation of Artisan IOL is an effective approach for correction of high myopia.A 5.5mm superior scleral tunnel incision in operation induces a +2.25D astigmatism at 175° meridian.

Objective To investigate the feasibility and the efficacy of ultrasound in promoting PLGA nanoparticle-mediated gene transfection in vivo.Methods Prostate cancer cell line PC-3 was used to generate xenografts in nude mice for gene transfection experiment in vivo.GFP plasmid was encapsulated in PLGA-based nanoparticles.Nanoparticles were injected into tumors locally.Two hours later,xenografts were exposed to ultrasound.Xenograft tissues were harvested in different time points to assess the efficiency of gene expression with regard to different parameters of ultrasound. Results PLGA nanoparticle-encapsulated GFP plasmids were readily transfected to PC-3 cells in vivo.A large number of GFP expressing cells were observed after exposed to ultrasound with 1.0 MHz 50% duty factor continuous wave.In comparison,ultrasound exposure with 40% duty factor pulse wave in vivo had low efficacy in terms of GFP expression.No animal death was noticed due to ultrasound exposure.Conclusions Ultrasound exposure can enhance the release of plasmid DNA content delivered by PLGA nanoparticles in vivo,local exposure to ultrasound wave would be used in conjunction with PLGA nanoparticle-mediated targeted delivery to the tissue or organ of interest.
