ABSTRACT
Objective To investigate whether the gastric juice volume(GV)of obese women who took carbohydrate 2 hours before operation was equal to or less than that of those who are not routine drinking.Methods Obese patients undergoing elective laparoscopic gynecological surgery under general anesthesia with BMI of 28-32 kg/m2 and ASA grade of Ⅰ-Ⅱ,aged 18-65 years old were selected.The patients were divid-ed into the carbohydrate group(CHO group)and the fasting group(Control group)by random number table method,with 51 cases in each group.The Control group was fasted from 11 pm before surgery,while the CHO group was given 300 mL of carbohydrate orally 2 hours before anesthesia.The main outcome measure was compared with a non-inferiority limit(△)of 17 mL and the mean difference in gastric juice volume between the two groups in the right lateral decubitus position(RLDP)examined by gastric ultrasound.The secondary outcome measures included CSA in right lateral position under gastric ultrasound,Perlas classification,GV/kg,gastric juice pH value,patient satisfaction and gastric emptying time.Results The mean difference of gas-tric juice volume was 7.18 mL(95％CI:-0.06 to 14.43),and the upper limit of 95％CI was lower than the preset non-inferiority limit(△=17.05 mL).There was no statistically significant difference in the mean(standard deviation)gastric juice volume between the control group and the CHO group[40(26,66)mL vs.58(34,65)mL;P=0.43].The gastric volume GV/kg was similar in the two groups(P=0.66),and there was no significant difference in the number distribution of Perlas grades between the two groups(P＞0.05).There was significant difference in patient satisfaction between the two groups(P＜0.05).Conclusion Ac-cording to the evaluation of gastric ultrasound,compared with fasting at midnight,300ml carbohydrate intake at 2 hours before surgery is not inferior to fasting at midnight in terms of gastric fluid volume in obese women as assessed by gastric ultrasound.
ABSTRACT
Objective:To observe the clinical value of intracranial pressure (ICP) monitoring combined with target temperature management (TTM) in patients with acute anterior circulation ischemic stroke after mechanical thrombectomy.Methods:A prospective analysis was performed. Ninety-two patients with acute anterior circulation ischemic stroke who received mechanical thrombectomy from March 2019 to June 2022 in Department of Neurosurgery, He'nan Provincial People's Hospital were enrolled. Within 1-5 d of mechanical thrombectomy, these patients were randomly divided into observation group ( n=46) and control group ( n=46). The patients in observation group received comprehensive management for neurological critical illness through multimodal monitoring such as ICP real-time monitoring combined with TTM (controlling the core temperature at 33℃-35℃), while patients in control group received simple ICP real-time monitoring. ICP monitoring for both groups lasted for 5-7 d, and routine symptomatic support treatment was given. Stepwise treatment was adopted based on real-time changes of ICP. The differences in clinical data, ICP at different times, incidence of adverse events, length of hospital stay, mortality rate, and prognoses were compared between the 2 groups. Results:On the 2 nd, 3 rd, 4 th, and 5 th d of monitoring, the observation group had significantly decreased ICP compared with the control group ( P<0.05). Both observation group and control group had significantly increased ICP on the 2 nd, 3 rd, 4 th, and 5 th d of monitoring compared with that on the 1 st d of monitoring ( P<0.05). Compared with the control group, the observation group had statistically higher incidences of shivers and electrolyte disorders, and statistically lower incidences of unstable blood pressure, cerebral heart syndrome, septic shock, and cerebral hernia during hospitalization ( P<0.05). Compared with the control group, the observation group had significantly shortened hospital stay, and statistically lower modified Rankin scale (mRS) scores, higher Glasgow outcome scale-extended (GOS-E) scores, higher good prognosis rate, and lower mortality rate 6 months after mechanical thrombectomy ( P<0.05). Compared with the control group, the observation group had statistically lower incidences of postoperative cerebral hemorrhage conversion and recurrent cerebral infarction ( P<0.05). Kaplan-Meier survival analysis showed that the survival rate in the observation group was significantly higher than that in the control group ( P<0.05). Conclusion:ICP monitoring combined with TTM can reduce early complications, shorten hospital stay, reduce mortality, and improve long-term prognosis in patients with acute anterior circulation ischemic stroke after mechanical thrombectomy.
ABSTRACT
Objective To investigate the effect of Jiawei-Xiaoyao powder on the levels of somatotropin and vasoaetive intestinal peptide (VIP) in patients with non-erosive reflux disease (NERD).Methods Seventy patients with liver-stagnation and spleen-deficiency NERD who met the inclusion criteria were divided into two groups according to the random number table,35 in each group.The treatment group was orally administered with Jiawei-Xiaoyao powder,and the control group was given oral omeprazole enteric-coated tablets and domperidone.Both groups were treated for 8 weeks.Plasma somatotropin and VIP levels were measured by ELISA.Results After treatment,plasma somatotropin levels (210.96 ± 16.85 pg/ml vs.195.75 ± 12.62 pg/ml,t=4.274) in the treatment group were significantly higher than that in the control group (P＜0.01),and plasma VIP level (16.12 ± 1.41 pg/ml vs.18.57 ± 2.68 pg/ml,t=4.786) in the treatment group was significantly lower than that in the control group (P＜0.01).Conclusions The Jiawei-Xiaoyao powder could reduce plasma VIP level in NERD patients,increase plasma somatotropin levels of NERD.

ABSTRACT
Objective To investigate the feasibility and effectiveness of fast track surgery (FTS) in neurosurgery. Methods One hundred fifteen patients who underwent neurosurgery surgery in Henan Province People's Hospital from June 2012 to March 2014 were enrolled in this study. All the patients were divided into FTS group (62 cases) and the tra?ditional operation group (53 cases). The clinical index, postoperative hospital stay and hospitalization cost were compared between the two groups. Results The clinical index were significantly lower in FTS group than in traditional operation group (P<0.05). Length of hospital stay (days) and hospitalization cost of FTS group were significantly shorter and lower in FTS group compared with traditonal operation group (8±1 vs. 11±2 days and RMB 4.58 ±0.75 vs. 5.78 ±0.64 ten thou?sand, respectively) (P<0.05). Conclusion FTS in neurosurgery operation is an all-new concept for surgery which can ef?fectively reduce postoperative complications, shorten length of hospital stay, decrease hospitalization cost and promote postoperative recovery.
ABSTRACT
Objective To investigate the formaldehyde pollution in a tunnel. Methods The concentration of formaldehyde was determined in rooms for different function,in rooms with different number of furniture,in different position in a tunnel and at different time of using air cleaner in Oct. 2006. Results The total rate of exceed standard of formaldehyde level in the tunnel was 82.9%,the rate of exceed standard in the rooms disposed by all the furniture was 100%,the rate of exceed standard in the front of the tunnel was lowest (63.6%). Using the air cleaner,the rate of exceed standard decreased in degree. Conclusion The main source of formaldehyde pollution in a tunnel is furniture,formaldehyde is the main air pollutant in a tunnel.
