Objective To investigate the distribution and synaptic connectivity of neuropeptide Y (NPY)-like immunoreactivity (IR) in Bullfrog retina, Rana Calesbeiana, especially in the inner plexiform layer. Methods Light microscopy immunofluorescence and post-embedding colloidal gold labeling electron microscopy techniques were employed in this study. Results NPY immunoreactivity was associated with a small population of amacrine cell bodies in the inner nuclear layer and cell processes, ramified with 3 distinct bands, in the inner plexiform layer. As for ultrastructure, quantitative analysis showed that NPY-IR amacrine cell processes were most often presynaptic to NPY negative amacrine cell processes (49.7%) and ganglion cell dendrites (49.3%). NPY-IR amacrine cells predominantly received synaptic input from bipolar cell axon terminals (86%), while a few input from other amacrine cell processes (14%). Conclusion NPY-IR in Bullfrog retina is mainly distributed in the inner part and predominately receives excitatory glutamate modulation from bipolar cells.

Objective To analyze the clinical efficacy and safety of laparoscopic and open uterine myomectomy.Methods 160 cases of uterine fibroids diagnosed by our hospital from April 2012 to April 2016 were selected as study cases.The patients were divided into two groups according to the order of treatment.80 patients in the control group received open uterine myoma rejection.80 patients in the observation group received laparoscopic myomectomy.The clinical treatment effect and complication were analyzed.Results The operation time,amount of intraoperative blood loss and the incision size of the observation group were (78.46 ± 10.31)min,(86.24 ±7.65) mL,(25.36 ± 1.28) mm,respectively,which were significantly less than those in the control group,the differences were statistically significant (t =6.57,6.81,7.66,all P ＜ 0.05).The time of postoperative body temperature recovery,time of anal exhaust,time of bedtime and the hospitalization time of the observation group were (24.16 ±3.81)h,(18.29 ± 4.36)h,(11.38± 2.06)h,(4.63 ± 1.51)d,respectively,which were significantly shorter than those in the control group (t =6.25,7.38,7.70,6.27,all P ＜ 0.05).The operative rate and postoperative analgesia rate of the observation group were 6.25％ and 11.25％,respectively,which were significantly lower than those of the control group (x2 =8.33,9.07,all P ＜ 0.05).The incidence rate of postoperative complications was 6.25％ in the observation group,which was significantly lower than 25.00％ in the control group,the difference was statistically significant (x2 =8.65,P ＜ 0.05).Conclusion Laparoscopic myomectomy has the advantages of less trauma,less bleeding,quick recovery and less complication,and high safety.It is the ideal technique for the treatment of uterine fibroids,which is worthy of promotion and application.

Objective: Large-conductance calcium-activated potassium (BKCa) channel modulates vascular smooth muscle tone. In the present study, we tested the hypothesis that salt, one of the factors which significantly influence blood pressure (BP), can regulate BKCa activity and then elevate blood pressure. Methods: Male Sprague-Dawley rats aged 6 weeks were randomized into high salt diet group (HS) and control group, fed with high salt diet (containing 5% NaCl) and standard rat chow (containing 0.4% NaCl) respectively for 16 weeks. Tail systolic blood pressure (SBP), body weight (BW) and 24-hour urinary output were tested every 4 weeks. Content of urinary Na+ was detected using flame spectrophotometrical method. At the end of 16 weeks, all the rats were killed, the mesenteric arteries were obtained, and single mesenteric smooth muscle cells were isolated at once. The resting membrane potential (Em), the total potassium currents and the currents after perfusion with TEA solution of the cells were all recorded by whole cell patch clamp. The transcriptions of BKCa channel α and β1 subunits in mesenteric arterial vascular smooth muscle cells (VSMC) of each group were calculated by real-time RT-PCR. Results: There was no difference in SBP and BW at each stage between control group and HS group; the urinary Na+ level in HS animals was elevated significantly after 4 weeks. The negative values of Em in HS group VSMCs were reduced compared with those in the control group. Transcriptions of β1 subunit of BKCa channels were decreased in HS group, but α subunit transcriptions did not differ between the two groups. Whole cell potassium currents did not differ between HS and control groups, but BK Ca currents of HS group VSMCs were lower than those of control group ones. Conclusion: Even without elevating SBP, salt-loading can still modulate the expression and activity of BKCa channel in the mesenteric arterial VSMC and elevate vascular tone.
