OBJECTIVETo observe the acupuncture effect on urinary retention after spinal anesthesia.

METHODSOne hundred and fifty-four patients with spinal anesthesia were randomized into an observation group (80 cases) and a control group (74 cases). In the observation group, the electroacupuncture was applied to bilateral Fushe (SP 13) and Shuidao (ST 28); 2 Hz/50 Hz, retaining for 30 min. One treatment was required. In the control group, no any intervention was applied after operation. The incidence of the postoperative urinary retention, the time of the first automatic micturition since 30 min after spinal anesthesia, the volume of the first micturition, the postoperative urine condition, the lower abdominal distention, incomplete urination and the others were observed.

RESULTSThe incidence of urinary retention in the observation group was lower than that in the control group; the first automatic micturition in 30 min after spinal anesthesia was earlier than that in the control group; the comfortable urination rate was higher than that in the control group; the incidence of incomplete urination and lower abdominal distention were lower than those in the control group. The differences were significant in comparison of the two groups (all P<0.05).

CONCLUSIONAcupuncture apparently shortens the time of first automatic micturition after spinal anesthesia and promotes the recovery of bladder urinary reflection. This therapy acts on promoting urination and reducing postoperative urinary retention.

Objective: To investigate the non-specific and inaccurate amplification in cases of highly similar sequences among family members and the length heterogeneity of mature microRNA ( miRNA) ,and find a condition that discriminates maximally among similar miRNA family members and detects the accurate expression level of miRNAs. Methods: Primers with their mismatches and/or 3' end at different positions were designed. Amplification efficiencies were compared using matched and various mismatched primers by RNA-tailing and primer-extension RT-PCR at different annealing temperatures. Expression levels of several miRNAs in mouse brain were compared using miRNA specific primers with different termini. Results: Raising annealing temperatures 12℃-14℃above the T_m of the primers maximally increased amplification specificity without sacrificing sensitivity. Primers designed with their termini on or near variant positions could efficiently discriminate between miRNA isoforms. Using primers that terminated before the end of the mature miRNA did not miss the detection of shorter mature miRNA and provided accurate expression levels. Conclusion: Careful primer design and higher annealing temperature can increase specificity and accuracy of real time PCR miRNA detection.

Objective To investigate clinical significance of counting follicles classification by three-dimensional imaging with sonography based automated volume calculation(SonoAVC)in the diagnosis of polycystic ovary syndrome(PCOS).Methods Eighty cases with PCOS were counted classified follicles and determined ovarian volume by three-dimensional(3D)imaging with SonoAVC method matched with 60 infertile women with fallopian tube or male factors as control.Main clinical.biological and other ultrasonographic markers were assessed during the early follicular phase,and the relationship between the follicle number range per ovary or the volume per ovary and the major hormonal features of PCOS was studied.Results Three-dimensional ultrasound imaging with SonoAVC methed provides a new path for objective quantitative assessment of follicle count.ovarian volume,total follicle numbers.The volume of (11 ±8)ml,total numbers of 27 ±14 follicle and number of22 ±19 follicle with diameter of≥2-＜6 mm in PCOS patients were significantly higher than(6 ±4)ml in ovarian volume.6 ±4 in total follicles and 2 ±3 in follicle with diameter of≥2-＜6 mm in controls(P＜0.05).while follicles were similar for the≥6-≤9mm range(P＞0.05).Total follicle numbers and follicles≥2-＜6 mm had significantly positive relationships with ovarian volume ( r= 0. 600, 0. 618, P＜0. 01 ) and level of testosterones ( r= 0. 364,0. 291, P＜0.05), follicles ≥2-＜6 mm also had significantly positive relationships with total follicle number (r=0. 916,P＜0. 01 ). The follicles within the ≥6 - ≤9 mm range was significantly and negatively related to ovarian volume and total follicle numbers ( r = - 0. 618, - 0. 263, all P = 0. 001 ), but no significantly related to the major hormonal features of PCOS. The ovarian volume was significantly positively related with luteinizing hormone ( LH)/follicle stimulating hormone (FSH) ratio ( r= 0. 282, P = 0. 010)but negatively related to FSH level (r = - 0. 226, P = 0. 042). Conclusions Ovarian volume, total follicle numbers and follicles ≥2 - ＜6 mm in PCOS patients were significantly higher than those in controls. The larger ovarian volume might produce more total follicle and follicles ≥ 2 - ＜6 mm. The higher level of testosterone might produce more total follicle probably, which mainly result in more follicles ≥2 -＜6 mm.These morphologically ultrasonographic characteristics could reflect pathophysiological changes in PCOS. Obviously, it has important clinical significance to count follicles in patients with PCOS by the threedimensional ultrasound imaging with SonoAVC method.
