Combination of corpus cavernosum flushing and surgical shunt for low-flow priapism / 局解手术学杂志

Objective To evaluate the efficacy of corpus cavernosum flushing combined with surgical shunt in the treatment of low-flow priapism(LFP).Methods We retrospectively reviewed 10 cases of LFP patients who were diagnosed and treated in our hospital from August 2010 to March 2017.The ages were from 28 to 67 years old,with average ages 44.8 years old,and the duration of erectile pain was 19 to 264 hours,with mean time 58.3 hours.Both doppler ultrasonography and analysis of blood gas indicated LFP.Comprehensive strategies were car-ried out to treat these patients.Results One case with chronic granulocytic leukemia(CGL) gave up treatment and died of acute transforma-tion three months later.Successful detumescence was achieved by combination of cavernosal flushing and different operation procedures for all of the other 9 cases.The follow-up duration ranged from 6 months to 12 months,which exhibited 3 cases with partial erectile dysfunction(ED) and 2 cases with complete ED respectively.Conclusion With the combination of cavernosal flushing and surgical shunt procedures,penis detumescence was successfully achieved.Treatment strategies should be carried out immediately as soon as LFP was diagnosed.

Gujing Maisiha Tablets combined with natural vitamin E for the treatment of idiopathic asthenospermia / 中华男科学杂志

Objective@#To investigate the therapeutic efficacy and safety of Gujing Maisiha Tablets combined with natural vitamin E in the treatment of idiopathic asthenospermia.@*METHODS@#This study included 135 outpatients with idiopathic asthenospermia received in our hospital from February 2015 to January 2016. We randomly divided them into a treatment group (n = 65, aged 22－44 ［mean 32.8］ yr) and a control group (n = 55, aged 21－43 ［mean 33.7］ yr) to be treated with Gujing Maisiha Tablets combined with natural vitamin E or natural vitamin E only, both for 90 days. We obtained total sperm motility and the percentage of progressively motile sperm (PMS) from the patients before and after medication and evaluated the clinical effects by comparing the collected parameters and pregnancy rates between the two groups.@*RESULTS@#The baseline total sperm motility and PMS were (25.23 ± 5.57)% and (17.53 ± 5.78)% in the treatment group, with no statistically significant differences from (26.05 ± 6.77)% and (15.11 ± 6.55)% in the control (P >0.05). After 90 days of medication, both the treatment and the control groups showed remarkable increases in total sperm motility (［48.73 ± 8.66］% and ［36.54 ± 8.09］%, P <0.05) and PMS (［32.77 ± 6.04］% and ［26.99 ± 6.87］%, P <0.05). However, both total sperm motility and PMS were significantly higher in the treatment than in the control group after medication (P <0.05), and so was the total rate of clinical effectiveness (73.85% vs 54.55%, P <0.05). No adverse reactions were observed in either of the two groups during the treatment.@*CONCLUSIONS@#Gujing Maisiha Tablets combined with natural vitamin E is safe and effective for the treatment of idiopathic asthenospermia.

Role of angiotensin II and JAK2 signal pathway in transdifferentation of renal tubular cells in mice after acute ischemic followed by reperfusion / 中华病理学杂志

<p><b>OBJECTIVE</b>To investigate the effect of angiotensin (Ang)II and its Janns-activated kinase-2 (JAK2) signal pathway in transdifferentiation of renal tubular cells under the challenge of acute ischemic reperfusion injury.</p><p><b>METHODS</b>Models of acute ischemic reperfusion injury were established and the level of local AngII, a key element of renin-angiotensin system (RAS), in kidney was measured using radioimmunity technique. The expression of alpha-smooth muscle actin (alpha-SMA), a phenotype of mesenchymal cells, was detected by RT-PCR and immunohistochemistry methods. Renal tubule cells (NRK-52E) were cultured with various concentration of AngII, followed by blocking of PD123319, AngII receptor 2 antagonist, and AG490, an inhibitor of JAK2 signal pathway.</p><p><b>RESULTS</b>AngII of kidney tissue increased immediately after acute ischemic-reperfusion injury, in time dependent fashion. Expression of alpha-SMA in renal tubule cells was found at 48 hours after ischemic-reperfusion injury and in NRK-52E cells treated by high concentration of AngII and was dose and time dependent. The peak of alpha-SMA expression was seen after 30 minute treatment at the dose of 10(-9) mol/L, which was interrupted by both of PD123319 and AG490.</p><p><b>CONCLUSIONS</b>Transdifferentiation of renal tubular epithelial cells occurs under acute ischemic-reperfusion injury. Local renin-angiotensin system may play a role in the transdifferentiation of TEC through AT2 receptor and its JAK2 signal pathway.</p>
