Objective To investigate preventive effect of Huanshao capsule on postoperative re-currence of moderate to severe intrauterine adhesion and its impact on postoperative pregnancy rates.Methods A total of 163 patients with moderate to severe intrauterine adhesion after surgery were se-lected as study subjects,and randomly divided into observation group(n=82)and control group(n=81).The control group received conventional treatment,while the observation group additionally took Huanshao capsule postoperatively.Serum fibronectin(FN),laminin(LN),vascular endothelial growth factor(VEGF)and transforming growth factor-β1(TGF-β1)levels were compared between two groups at 1 month,3 and 6 months postoperatively.Endometrial thickness,uterine artery blood flow resistance index(RI),postoperative pregnancy rates and quality of life scores were also com-pared.Results At 3 and 6 months postoperatively,serum FN,LN and VEGF levels in the observa-tion group were lower than those in the control group(P＜0.05).At 6 months postoperatively,serum TGF-β1 in the observation group was lower than that in the control group,with statistically significant difference(P＜0.05).At 3 and 6 months after surgery,endometrial thickness in the observation group was significantly higher,uterine artery flow RI was significantly lower than,and scores of various quality of life(physiological function,physical pain,social function and mental health)were signifi-cantly higher than those in the control group(P＜0.05).At 6 and 9 months postoperatively,the pregnancy rate in the observation group was higher than that in the control group,with statistically sig-nificant differences(P＜0.05).Conclusion Huanshao capsule can significantly reduce serum FN,LN,VEGF and TGF-β1 levels in patients with moderate to severe intrauterine adhesion after surgery,improve the postoperative endometrial environment,and increase postoperative pregnancy rates.

Objective:To study the clinical effects of modified surgical method with H-uvulopalatopharyngoplasty(H-UPPP)and traditional surgical method in the treatment of obstructive sleep apnea hypopnea syndrome(OSAHS)in children.Methods:The clini-cal data of 364 pediatric patients with OSAHS were retrospectively analyzed.The patients were divided into 2 groups and treated by low-temperature plasma knife radio frequency ablation for bilateral tonsil removal combined with H-UPPP(group A,n=204)and low-temperature plasma knife radio frequency ablation only(group B,n=160)respectively.The operative time,intraoperative bleed-ing,postoperative secondary bleeding,VAS of pain following operation,postoperative traumatic white film shedding time,OAH1,LSaO2,ESS scores and complications of the 2 groups were compared.Results:In group A the operative time,intraoperative bleed-ing,VAS,OAHI and ESS scores were lower than those in group B(P＜0.05),wile postoperative traumatic white film detachment time and LSaO2 were higher(P＜0.05).No statistically significant difference in terms of the number of cases of postoperative seconda-ry bleeding and complications was observed between the 2 groups(P＞0.05).Conclusion:The combination of low-temperature plas-ma radio frequency ablation and H-UPPP for the treatment of OSAHS may provide clear intraoperative view,and may improve the treatment effects.

Objective:To implore the effect of continuous positive airway pressure (CPAP) therapy on dizziness patients and its mechanism. Method:Seventy-five dizziness patients were enrolled. All patients accepted polysomnographic test, dizziness handicap inventory, Pitsburgh sleep quality index and Epworth sleepiness scale before and after CPAP therapy. Patients were divided into two groups according to a polysomnographic test: OSAHS group (AHI≥15) and without OSAHS group (AHI<15); divided into three groups according to dizziness handicap inventory score: mild dizziness group (0P<0.01). ②The effectiveness of CPAP therapy between OSAHS group and without OSAHS group has no difference (P>0.05), but CPAP therapy could ameliorate sleep disorder of the OSAHS group. ③Different levels of dizziness had no impact on improving DHI during CPAP therapy. However, the effect on sleep improvement decreased when patients had heavier dizziness. ④Treating by CPAP after three months could significantly improve patients dizziness (P<0.01). ⑤The dizziness of the patients in younger old group and old group have significant improvement after CPAP therapy (P<0.01). However, only younger old group has better sleep. Conclusion:CPAP therapy could dramatically improve dizziness in patients with sleep disorders.

PURPOSE: Pulmonary Kv channels are thought to play a crucial role in the regulation of cell proliferation and apoptosis. Previous studies have shown that fluoxetine upregulated the expression of Kv1.5 and prevented pulmonary arterial hypertension in monocrotaline-induced or hypoxia-induced rats and mice. The current study was designed to test how fluoxetine regulates Kv1.5 channels, subsequently promoting apoptosis in human PASMCs cultured in vitro. MATERIALS AND METHODS: Human PASMCs were incubated with low-serum DMEM, ET-1, and fluoxetine with and without ET-1 separately for 72 h. Then the proliferation, apoptosis, and expression of TRPC1 and Kv1.5 were detected. RESULTS: In the ET-1 induced group, the upregulation of TRPC1 and down regulation of Kv1.5 enhanced proliferation and anti-apoptosis, which was reversed when treated with fluoxetine. The decreased expression of TRPC1 increased the expression of Kv1.5, subsequently inhibiting proliferation while promoting apoptosis. CONCLUSION: The results from the present study suggested that fluoxetine protects against big endothelin-1 induced anti-apoptosis and rescues Kv1.5 channels in human pulmonary arterial smooth muscle cells, potentially by decreasing intracellular concentrations of Ca2+.
