OBJECTIVETo investigate the effect of neuroendoscope on surgery.

METHODS315 patients were treated with neuroendoscope. Endoscopic neurosurgery (EN) was used in 219 patients, endoscope-assisted microneurosurgery (EAM) in 72, and endoscope-controlled microneurosurgery (ECM) in 24.

RESULTS201 (91.8%) of the 219 patients underwent EN effectively. In 72 patients who underwent EAM there was less retraction during tumor removal and visual control was improved. 21 (87.5%) of the 24 patients underwent ECM effectively. No severe complications were observed.

CONCLUSIONNeuroendoscopy can reduce tissue trauma, improve visualization during tumor removal, and reduce complications.

A recombinant strain Escherichia coli DH5alpha(pMD19-glnA) including Bacillus subtilis glnA gene was constructed. Capillary electrophoresis and nuclear magnetic resonance were used to determine qualitatively the product of transformation by recombinant strain, and the relative level of mRNA expression of glnA was also determined by fluorescence quantitative RT-PCR. Subsequently, SDS-PAGE (polyacrylamide gel electrophoresis) was used to analysis the relative level of protein. Surprisingly, there was no increase of glutamine production in this recombinant strain, but an obvious increase in the GABA (gamma-aminobutyric acid ) production. It was showed in the experiment that protein expression of the glutamine synthetase did not increase, although glnA gene can be transcribed normally in this recombined strain. The phenomenon of exogenous glnA gene interfering metabolism of Escherichia coli was worthy of further study.

Pulsatile blood flow plays an important role in maintaining normal vascular endothelial function. Quantitative measurement of pulsatility of artery blood pressure and blood flow in dogs and effects of enhanced external counterpulsation (EECP) on the pulsatility were taken in this study. Common carotid artery blood pressure and blood flow were measured in 6 beagle dogs that had suffered from an acute myocardial infarction 6 weeks before. A 6F tip transducer catheter was inserted into the right common carotid artery to measure blood pressure, and blood flow was measured in the left common carotid artery by an electromagnetic blood flow probe under anesthesia before and during EECP. Blood pulse pressure, pulsatility index (ratio of peak pressure to end diastolic pressure) and standard deviation of blood pressure were calculated to evaluate the pulsatility of arterial blood pressure. Blood pulse flow, pulsatility index (ratio of peak flow to trough flow) and standard deviation of blood flow were calculated to evaluate the pulsatility of blood flow. Mean vascular resistance (MVR) was calculated as MVR = mean blood pressure/mean blood flow. Blood pulse pressure, pulsatility index and standard deviation of blood pressure were elevated from 30 +/- 9 mmHg, 1.26 +/- 0.05 and 8.7 +/- 2.5 mmHg to 43 +/- 8 mmHg (P < 0.05), 1.54 +/- 0.13 and 12.4 +/- 2.0 mmHg (P < 0.05) before and during EECP, respectively. Blood pulse flow, pulsatility index and standard deviation of blood flow were elevated from 317 +/- 48 ml/min, 2.85 +/- 0.21 and 96 +/- 21 ml/min to 447 +/- 88 ml/min, 4.56 +/- 0.90 and 131 +/- 39 ml/min before and during EECP (P < 0.05). MVR was decreased from 578 +/- 72 before EECP to 476 +/- 85 Wood units during EECP(P < 0.05). These data demonstrate that EECP gives an elevation of pulsatility to blood pressure and blood flow, thus it may lead to the decrease of vascular resistance.

Pulsatile blood flow plays an important role in maintaining normal vascular endothelial function. Quantitative measurement of pulsatility of human arterial blood pressure and the influence of enhanced external counterpulsation (EECP) on the pulsatility were investigated in this study. Eight healthy young male volunteers aged 22 to 35 were included. A 4F tip transducer catheter was inserted under local anaesthesia into the radial artery up to the aortic arch. Intraarterial blood pressure was recorded before and during EECP. Blood pulse pressure, pulsatility index (ratio of peak pressure to end diastolic pressure) and standard deviation of blood pressure in 5 cardiac cycle was calculated to evaluate the pulsatility of arterial blood pressure. The results showed that blood pulse pressure, pulsatility index and standard deviation of blood pressure were elevated from 47 +/- 5 mmHg, 1.64 +/- 0.11 and 13.6 +/- 1.5 mmHg to 77 +/- 3 mmHg, 2.46 +/- 0.25 and 19.3 +/- 2.2 mmHg before and during EECP respectively (P < 0.05). Decreasing of systolic pressure and increasing of diastolic pressure during counterpulsation were also observed. EECP gives an elevation of pulsatility to human blood pressure.

Objective:To explore the effect of "ten needles in the stomach" on sleep perception of patients with spleen-gastric damp-heat insomnia based on the theory of "stomach discord, then sleep restlessness", to provide references for clinical diagnosis and treatment.Methods:The study subjects were 300 patients with insomnia from the sleep department and outpatient department of Shijiazhuang Traditional Chinese Medicine Hospital. According to the random number method, they were divided into the stomach ten needle group, the diazepam group, and the stomach ten needle plus diazepam group, with 100 in each group. Among them, the stomach ten needles group received "stomach ten needles" acupuncture treatment, the diazepam group was given diazepam therapy, and the stomach ten needles plus diazepam group was given diazepam combined with "stomach ten needles" acupuncture treatment. The Pittsburgh Sleep Quality Index (PSQI) scores, the self-rating disease symptom scale (SCL-90) scores, nighttime polysomnography (PSG) monitoring indicators, and the mean sleep latency (MSL) values were compared before and after treatment in the three groups. The difference in clinical efficacy between the two groups were observed.Results:The total effective rate was 94.0% (94/100) in the combined group, 77.0% (77/100) in the diazepam group, and 85.0% (85/100) in the stomach ten needle group. There were significant differences among the three groups ( χ2=11.56, P<0.01). After treatment, the daytime dysfunction, hypnotic drugs, sleep disturbance, sleep efficiency, sleep time, sleep time, sleep quality score and total score of the combined group were significantly lower than those in the diazepam group and the stomach ten needle group ( F=5.70, 3.65, 5.23, 6.37, 3.66, 6.19, 7.54, 6.40, all Ps<0.01); The scores of SCL-90 and MSL were significantly lower than those in the diazepam group and stomach ten needle group ( F=8.97, 7.53, all Ps<0.01). In the combined group, NWAK [(1.36 ± 0.87) times vs. (2.69 ± 1.15) times, (2.11 ± 1.05) times, F=5.88], SOL [(13.62 ± 5.85) min vs. (25.06 ± 9.42) min, (19.78 ± 7.63) min, F=6.49], N1/TST [(5.69 ± 1.09)% vs. (12.65 ± 2.58)%, (8.49 ± 2.45)%, F=5.13], N2/TST [(51.07 ± 10 2.06)% vs. (58.36 ± 2.18)%, (55.61 ± 2.04)%, F=9.86] were significantly lower than those in the diazepam group and stomach ten needle group ( P<0.01), SE [(90.33 ± 2.89)% vs. (85.39 ± 2.75)%, (87.53 ± 2.69)%, F=8.36], TST [(449.32 ± 23.65) min vs. (421.66 ± 25.33) min, (431.26 ± 25.98) min, F=8.26], REM/TST [(23.87 ± 4.52)% vs. (14.52 ± 3.87)%, (18.36 ± 3.25)%, F=5.34], N3/TST [(18.69 ± 2.02)% vs. (10.31 ± 1.64)%, (14.89 ± 1.74)%, F=7.69] were significantly higher than those in the diazepam group and stomach ten needle group ( P<0.01). Conclusion:Based on the "stomach discord, sleep restlessness" theory, the ten needles on the stomach can treat insomnia and improve psychological state and sleep quality, with the functions of clearing the damp and heat of the middle joker, regulating the lifting and lowering of qi in the middle.
