Objective:To investigate the effect of dexmedetomidine-based anesthesia on gastrointestinal function in the patients undergoing laparoscopic radical resection for colorectal cancer.Methods:One hundred patients, aged 40-70 yr, with body mass index of 18-29 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅱ to Ⅲ, scheduled for elective laparoscopic radical resection for colorectal cancer, were divided into 2 groups ( n=50 each) using a random number table method: dexmedetomidine group (group D) and control group (group C). In group D, dexmedetomidine was intravenously infused as a bolus of 0.5 μg/kg at 10 min before anesthesia induction, followed by a continuous infusion of 0.5 μg·kg - 1·h - 1 until the end of surgery. In group C, the equal volume of normal saline was administered at the same time points. Patient-controlled intravenous analgesia was performed with hydromorphone, flurbiprofen, and metoclopramide after operation. Oxycodone was taken orally for rescue analgesia when visual analog scale score> 3. Serum intestinal fatty acid-binding protein concentrations were determined using an enzyme-linked immunosorbent assay at 10 min before anesthesia induction (T 1), 10 min after establishing pneumoperitoneum (T 2), immediately after tumor resection (T 3), 30 min before the end of surgery (T 4), and 1 h after the end of surgery (T 5). Gastrointestinal function was assessed using the I-FEED scoring system at 1-6 days after surgery.The intraoperative consumption of propofol and remifentanil, time to first flatus, first defecation and first oral intake and duration of hospital stay after surgery, and requirement for rescue analgesia within 3 days after surgery were recorded. Results:Compared with group C, the serum intestinal fatty acid-binding protein concentrations were significantly decreased at T 3-T 5, the I-FEED scores were decreased on postoperative days 3-5, the intraoperative consumption of propofol and remifentanil was decreased, and the time to first flatus, first defecation and first oral intake and duration of hospital stay were shortened ( P<0.05), and no significant difference was found in the rate of rescue analgesia in group D ( P>0.05). Conclusions:Dexmedetomidine-based anesthesia can promote the recovery of postoperative gastrointestinal function in the patients undergoing laparoscopic radical resection for colorectal cancer.

Objective:To investigate the efficacy of recapping laminoplasty preserving the continuity of superior spinous ligament in the treatment of benign tumors in the lumbar spinal canal.Methods:A retrospective analysis was performed. The clinical data of 23 patients with benign tumors in lumbar spinal canal, admitted to our hospital from March 2018 to March 2020, were collected. Follow up was performed for 12-23 months; Japanese Orthopaedic Association (JOA) scores were used for efficacy evaluation. X-ray, CT and MRI were used for imaging evaluation.Results:The number of replanted lamina was 1-4, with an average of 2.2. The surgical duration was (77.2±22.7) min, ranged from 67 min to 146 min; and the amount of intraoperative bleeding was (127±32.6) mL, ranged from 90-290 mL. The tumors were completely removed in all patients, and there were 2 patients complicated with cerebrospinal fluid leakage, and the wound healed after electrolyte supplement and local pressure treatment. No spinal cord injury, epidural hematoma, infection or other related complications were noted. The JOA scores increased from 11.85±1.38 before surgery to 23.22±2.47 at the last follow-up, with significant difference ( t=18.505, P<0.001). Of them, 10 had excellent efficacy, 9 had good efficacy, and 4 had medium efficacy, enjoying an excellent and good rate of 82.6%. Lumbar lordosis angle (LLA) was (51.58±2.39)°at the last follow-up, which showed no significant difference as compared with the preoperative LLA ([52.24±3.17]°, t=0.672, P=0.505). Imaging results showed that there was no spondylolisthesis or instability of lumbar spine, no recurrence of tumors was noted, and no displacement of lamina or secondary reduction of spinal canal volume were noted. Conclusion:The treatment of benign tumors in lumbar spinal canal by modified recapping laminoplasty preserving the continuity of superior spinous ligament can restore the normal anatomical structure of lumbar spinal canal, achieve no bone loss and maintain lumbar curvature well.

Objective:To observe the application effect of high-flow nasal canula oxygen therapy (HFNC) after extubation in patients with mechanical ventilation (MV) in the intensive care unit (ICU).Methods:A prospective study was conducted. From January 2018 to June 2020, 163 MV patients admitted to Yijishan Hospital of Wannan Medical College were enrolled, and they were divided into HFNC group (82 cases) and traditional oxygen therapy group (81 cases) according to the oxygen therapy model. The patients included in the study were given conventional treatment according to their condition. In the HFNC group, oxygen was inhaled by a nasal high-flow humidification therapy instrument. The gas flow was gradually increased from 35 L/min to 60 L/min according to the patient's tolerance, and the temperature was set at 34-37 ℃. The fraction of inspiration oxygen (FiO 2) was set according to the patient's pulse oxygen saturation (SpO 2) and SpO 2 was maintained at 0.95-0.98. A disposable oxygen mask or nasal cannula was used to inhale oxygen in the traditional oxygen therapy group, and the oxygen flow was 5-8 L/min, maintaining the patient's SpO 2 at 0.95-0.98. The differences in MV duration before extubation, total MV duration, intubation time, reintubation time, extubation failure rate, ICU mortality, ICU stay, and in-hospital stay were compared between the two groups, and weaning failure were analyzed. Results:There was no significant differences in MV duration before extubation (days: 4.33±3.83 vs. 4.15±3.03), tracheal intubation duration (days: 4.34±1.87 vs. 4.20±3.35), ICU mortality [4.9% (4/82) vs. 3.7% (3/81)] and in-hospital stay [days: 28.93 (15.00, 32.00) vs. 27.69 (15.00, 38.00)] between HFNC group and traditional oxygen therapy group (all P > 0.05). The total MV duration in the HFNC group (days: 4.48±2.43 vs. 5.67±3.84) and ICU stay [days: 6.57 (4.00, 7.00) vs. 7.74 (5.00, 9.00)] were significantly shorter than those in the traditional oxygen therapy group, the reintubation duration of the HFNC group was significantly longer than that of the traditional oxygen therapy group (hours: 35.75±10.15 vs. 19.92±13.12), and the weaning failure rate was significantly lower than that of the traditional oxygen therapy group [4.9% (4/82) vs. 16.0% (13/81), all P < 0.05]. Among the reasons for weaning failure traditional oxygen therapy group had lower ability of airway secretion clearance than that of the HFNC group [8.64% (7/81) vs. 0% (0/82), P < 0.05], there was no statistically differences in the morbidity of heart failure, respiratory muscle weakness, hypoxemia, and change of consciousness between the two groups. Conclusion:For MV patients in the ICU, the sequential application of HFNC after extubation can reduce the rate of weaning failure and the incidence of adverse events, shorten the length of ICU stay.

OBJECTIVE：To study the spectrum-effect relationship of HPLC finger print of different polar parts of Ampelopsis grossedentata with its in vivo anti-inflammatory effect. METHODS ：A. grossedentata was reflux extracted with 70％ ethanol，then extracted with petroleum ether ，chloroform，ethyl acetate and water saturated n-butanol；or it was directly decocted with water and then concentrated to obtain different polar parts.

Objective: To investigate the incidence and prognosis of cognitive impairment and to find out the risk factors associated with the outcome for better understanding and preventing cognitive impairment in maintenance hemodialysis (MHD) patients. Methods: The patients who met the criteria as below: MHD patients (≥3 months) in Renji Hospital, Shanghai Jiao Tong University School of Medicine from January 2000 to July 2014, ≥18 years old were enrolled and could carry on the montreal cognitive assessment (MoCA) of voluntary cooperation. According to the score of MoCA, all enrolled patients were divided into two groups: cognitive impairment (MoCA<26) group and non-cognitive impairment (MoCA≥26) group. The follow-up period was 3 years. There were 130 males, and the incidence, demography data, medical history, hemodialysis data, laboratory examination and prognosis of cognitive impairment in hemodialysis patients were prospectively compared and analyzed. Logistic regression analysis was used to investigate the risk factors of cognitive impairment. Kaplan-Meier survival curve and Cox regression model were used for prognostic analysis. Results: A total of 219 MHD patients were enrolled. The incidence of cognitive impairment in MHD patients was 51.6%. There were 130 males, and the ratio of male to female was 1.46∶1. Age was (60.07±12.44) years old and dialysis vintage was (100.79±70.23) months. Compared with non-cognitive impairment group (n=106), patients in cognitive impairment group (n=113) were older, and had higher proportion of education status<12 years, history of diabetes and anuria (all P<0.05); however, the post-dialysis systolic pressure, pre-dialysis diastolic pressure, post-dialysis diastolic pressure, platelet and spKt/V were lower (all P<0.05). Multivariate logistic regression analysis showed that education status<12 years (OR=3.428, 95%CI 1.919-6.125, P<0.001), post-dialysis diastolic pressure<73 mmHg (OR=2.234, 95%CI 1.253-3.984, P=0.006) and spKt/V<1.72(OR=1.982, 95%CI 1.102-3.564, P=0.022) were the independent risk factors for cognitive impairment in MHD patients. The Kaplan-Meier survival curve analysis showed that the survival rate of patients with cognitive impairment was lower than that of non-cognitive impairment group in MHD patients during 3 years follow-up (χ²=3.977, P=0.046). Multivariate Cox regression analysis showed that cognitive impairment was an independent risk factor for death in MHD patients (RR=2.661, 95%CI 0.967-7.321, P=0.058). Conclusions Cognitive impairment is one of the common complications and an independent risk factor for death in MHD patients. The mortality is high in patients who suffer cognitive impairment. Education status<12 years, post-dialysis diastolic pressure<73 mmHg and spKt/V<1.72 are the independent risk factors for cognitive impairment in MHD patients.

Objective To analyze the role of telehealth?based dialysis registration systems in real?time and dynamic reflection of renal anemia in hemodialysis (HD) patients, and discuss the prospect of its application in dialysis registration management. Methods The Red China project was to build up a dialysis registration system based on the WeChat mobile terminal platform. Demographic and baseline laboratory parameters such as age, gender, primary disease, dialysis age, creatinine were recorded in this system. Hemoglobin (Hb) level was monthly recorded. The platform generated Hb statistics report for each HD center monthly, including the detection rate, target rate and the distribution level of Hb, and released it to physicians through the WeChat terminal of mobile phone. After that, physicians could change the treatment of anemia individually on basis of this report. Here the demographic and baseline laboratory parameters, the detection rate, target rate, the average level and the distribution of Hb from June 2015 to October 2017 after the project launched were analyzed. Results From June 2015 to October 2017, 8392 maintenance HD patients from 28 HD centers in Shanghai were enrolled, of whom 5059(60.3％) were male.The average rate age was (60.5 ± 13.7) years old. Baseline average Hb was (108.3±16.0) g/L. Baseline detection rate and target rate were 54.2％and 47.5％, respectively. After 28 months follow?up, the detection rate of Hb increased from 54.2％ to 73.6％ (P<0.001), the target rate of Hb increased from 47.5％ to 56.1％ (P<0.001), and the level of average Hb rose from (108.3±16.0) g/L to (110.7±16.0) g/L. The difference between average Hb in two consecutive months was less than 1.3 g/L. Conclusions The telehealth?based dialysis registration system can timely report the anemia situation of HD patients, which may improve the awareness rate of anemia, the degree of attention and the compliance of anemia monitoring, so as to improve the detection rate and target rate of Hb and reduce the fluctuation of Hb, which helps to maintain the HD patients to correct anemia in a timely, stable and long?term way. The telehealth?based dialysis registration system, as an improved mode of dialysis registration is a promising way for long?term management of renal anemia in dialysis patients.
