Transurethral electrotomy combined with seminal vesiculoscopy ejaculatory duct dilatation in treating patients with Müllerian duct cyst / 中南大学学报(医学版)

OBJECTIVE@#To evaluate the feasibility and efficacy of transurethral electrotomy combined with seminal vesiculoscopy ejaculatory duct dilatation in treating patients with Müllerian duct cyst. 
@*METHODS@#We retrospectively analyzed 12 infertile men due to Müllerian duct cyst between 2009 and 2012. They were diagnosed by semen analysis (including quantity of semen, pH and fructose), digital rectal examination, transrectal ultrasonography, magnetic resonance images and aspiration biopsy when necessary. All patients were treated by transurethral electrotomy combined with seminal vesiculoscopy ejaculatory duct dilatation and were followed up for 12 months. 
@*RESULTS@#A significant improvement of semen quality was achieved after surgery and the sperms could be seen. The patients' semen was analyzed for 3 times in 12 months and the results were normal. Semen volume and pure berries of the patients were increased after the operation compared with those before the operation (P<0.05). Spontaneous pregnancies were achieved in 3 patients 9-12 months after surgery. Four patients' seminal vesicle became smaller obviously.
@*CONCLUSION@#Transurethral electrotomy combined with seminal vesiculoscopy ejaculatory duct dilatation is effective and safe for the treatment of Müllerian duct cyst accompanied with ejaculatory duct obstruction.

Effects of thoracoscopic lobectomy on early-stage non-small cell lung cancer / 中国基层医药

Objective To discuss effects of thoracoscopic lobectomy on early-stage non-small cell lung cancer . Methods 60 patients with non-small cell lung cancer patients were randomly divided into two groups of 30 cases in each group using thoracoscopic lobectomy (VATS) treatment,as the VATS group,another group using traditional open surgery(TOS) therapy,TOS as a group.(1) Operative time,blood loss,postoperative drainage time,drainage, postoperative pain,postoperative bed days,after several days of hospitalization were compared between the two groups . (2) 1,3 and 5 days after surgery,serum C-reactive protein(CRP) and interleukin-6(IL-6)levels were compared. Results (1)were operative time,postoperative drainage time,pain time,bed time and hospitalization time in VATS group were (69.50 ±15.33)min,(60.23 ±9.75)h,(46.75 ±7.36)h,(3.54 ±1.58)d,(9.50 ±2.50)d,com-pared with TOS group (86.77 ±19.56)min,(66.50 ±10.50)h,(58.36 ±9.58)h,(5.50 ±1.55)d,(13.55 ± 3.18)d short d observed group blood loss ,drainage volume(161.55 ±25.54)mL,(155.75 ±23.18)mL,compared with TOS group(186.58 ±25.35)mL,(169.65 ±26.87)mL less,the difference was statistically significant (t =39.14,28.19,54.11,6.03,7.24,98.36,76.34,all P<0.05).(2) VATS group after 1,3 and 5 days CRP serum and were(79.58 ±22.15) mg/L,(97.23 ±28.16) mg/L,(98.44 ±27.19) mg/L,IL-6,respectively (69.36 ± 17.32) ng/L, ( 96.33 ±25.67 ) ng/L, ( 103.16 ±28.89 ) ng/L, were higher than the TOS group ( 97.84 ± 25.37)mg/L,(119.17 ±31.77)mg/L,(130.81 ±33.29)mg/L,(76.83 ±21.97)ng/L,(121.15 ±32.64)ng/L, (122.08 ±30.74)ng/L,the difference was statistically significant (t=70.12,58.33,69.17,64.34,79.58,92.17,all P<0.05).Conclusion VATS lobectomy for non-small cell lung cancer has better effects and safety .

ISSR Analysis for genetic diversity of Coptis chinensis / 中草药

Objective To discuss the genetic diversity of Coptis chinensis.Methods The genetic diversity of 78 individuals from seven populations was analyzed by inter-simple sequence repeat(ISSR).Results Twelve primers were selected to produce highly reproducible ISSR bands.Among 106 amplified bands,72 showed polymorphism,the percentage of polymorphic bands reached to 67.92%.Nei's gene diversity index(H)was 0.180 3,Shannon information index(I)was 0.283 2,Gst was 0.681 5.The genetic distance coefficient and genetic similarity were 0.089 4—0.184 6 and 0.832 1—0.912 7,respectively.ConclusionC.chinensis holds high genetic diversity and the majority of genetic variation occurs among the populations.By cluster analysis,the geographical distribution is very obvious.The ISSR marker could be used for the analysis of the genetic diversity and genetic variation of C.chinensis.
