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 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 investigate the feature of nosocomial infections of our hospital inpatients,and analyze the correlative factors,based on which effective methods are taken.METHODS An analysis was made on the basis of the survey,the data came from 58 324 hospitalized cases from 2003 to 2006.RESULTS Of them 2 509 cases were infected,the incidence was 4.30%.The lower respiratory tract ranked the first place (26.66%)and the highest infected rate was in Hematology Department(7.79%).The species were predominated by Gram-negatives(58.04%).CONCLUSIONS Strengthening the nosocomial infection management,the infection rate could be decreased after taking prevention measures according to various correlative factors.

Abstract?AlM: To study the effect of latanoprost combined with timolol treatment on visual function, intraocular pressure and ocular blood flow of open angle glaucoma.?METHODS:A total of 50 cases ( 59 eyes ) with open angle glaucoma were enrolled from January 2012 to May 2014 in our hospital department of ophthalmology, and divided into observation group and control group by adopting the random number table method. Patients in observation group were treated with latanoprost combined with timolol, patients in control group were treated only with timolol. Visual function, intraocular pressure and ocular blood flow were compared.?RESULTS:1, 2, 3 and 4wk after treatment, observation group during the day intraocular pressure, night intraocular pressure were significantly lower than that in control group, vision levels (0. 27±0. 03, 0. 36±0. 06, 0. 44± 0. 06, 0. 63 ± 0. 13 ) were significantly higher than that in control group; observation group peak systolic velocity (14. 41± 1. 73) cm/s, end diastolic velocity (4. 18 ± 0. 67) cm/s were significantly higher than that in control group;vascular resistance index ( 0. 58 ± 0. 07 ) was significantly lower than that in control group.? CONCLUSlON: Latanoprost combined with timolol treatment can reduce intraocular pressure, increase blood flow of central retinal artery, reduce vascular resistance, improve visual acuity.

Objective: To study the optimum process of Ganmao Capsules(Rhizoma Coptidis, Herba Ephedrae, etc.). Methods : The extraction of Rhizoma Coptidis and Herba Ephedrae compared with Rhizoma Coptidis according to amount of berberine. The orthogonal design was used to select the optimum extraction according to amounts of berberine and ephedrine. Results : The extraction of Rhizoma Coptidis was better than that mixed Rhizoma Coptidis and Herba Ephedrae. Taking water as solvent, Rhizoma Coptidis was macerated for 0.5h and extracted in sequence three times with 12, 10 and 10 times volume of water extraction time for 1.5h, 1.0h and 1.0h, respectively. And Herba Ephedrae was macerated for 0.5h and extracted in sequence three times with 10, 8 and 8 times volume of water extraction time for 1.5h, 1.0h and 1.0h. Conclusion : The experimental results provided the basis for the ascertainment of extraction process of Rhizoma Coptidis and Herba Ephedrae preparation.

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.
