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: A series of Bobath concept, Bobath theoretical hypothesis and clinical practice were summarized, to proVide a better understanding of Bobath concept involved in nervous tissues repairing and functional reconstruction. METHODS: Articles concerning the Bobath treatment for stroke-related literature were retrieved in Highwire press, MEDLINE, and Google from 2001 to 2009, using the key words of "Bobath concept, stroke physical therapy". Data of each study were extracted and analyzed following retrieval. Inclusion criteria:①Bobath concept and its theoretical hypothesis. ②New development of Bobath concept in clinical practice. Exclusion criteria: Repetitive studies. The results of retrieved literatura were analyzed. RESULTS: The theoretical basis of Bobath concept is based on present-day knowledge of motor control, motor learning, neural and muscle plasticity, and biomechanics. The latest theories and viewpoints are rasourced from International Bobath Instructors Training Association and the British Bobath Tutors Association. They expounded on the Bobath concept from linking participation, activities and underlying impairments, organization of human behavior and motor control, the consequences of injury and dysfunction in the execution of movement, neural and muscle plasticity, motor learning and so. This article also discusses several important questions which meet in clinical practice. CONCLUSION: Bobath therapy, as a traditional method for stroke rehabilitation, is constantly absorbing the research results from current neuroscience, psychology and other disciplines, and blended with other treatments to promote the development of neuro-rehabilitation medicine.

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.

One biocontrol bacillus B3 was isolated from peanut rhizosphere, which showed a broad inhibition spectrum against various soil-borne plant phytopathogenic fungi. It was also found to be capable of utilizing beta-cypermethrin, chlorpyrifos and imidacloprid as the sole source of carbon for growth. The extent of degradation of them at initial concentration of 100 mg/L was 54.42%, 57.44% and 49.24% respectively within 7 days. Strain B3 was identified as Paenibacillus polymyxa based on morphological, physiological-biochemical properties, and 16S rRNA sequence analysis. This study indicated that strain B3 had potential application in biological control and soil bioremediation.
