OBJECTIVETo study protective effect of ulinastatin on perioperative cardiac function in elderly patients undergoing major gastrointestinal surgery.

METHODSSixty elderly patients (32 male and 28 female patients) aged 60-82 years scheduled for major gastrointestinal surgery were randomized into ulinastatin group and control group. The patients in ulinastatin group received 2×10(5) U ulinastatin rapidly administered via a intravenous pump immediately before operation with subsequent continuous infusion at the rate of 1×10(5) U until the completion of surgery, and those in the control group received the same amount of saline instead. In both groups, the mean arterial pressure (MAP), heart rate (HR), left ventricular ejection fraction (LVEF), and cardiac output (CO) were monitored immediately before surgery (T0) and at 1 h (T1), 2 h (T2) and 3 h (T3) after the start of surgery. The total dopamine dose used was recorded at the end of surgery, and blood samples were collected at T0 and at 6 h (T4) and 12 h (T5) after the operation for determination of serum levels of cTn, CK-MB and BNP.

RESULTSIn both groups, MAP, LVEF and CO were significantly decreased at T2 and T3 (P<0.05) and serum levels of cTn, CK-MB and BNP significantly increased at T4 and T5 compared to those at T0 (P<0.05). Compared with the control group, the patients in ulinastatin group showed significantly higher MAP, LVEF and CO at T2 and T3 and lower serum levels of cTn, CK-MB and BNP at T4 and T5.

CONCLUSIONUlinastatin offers effective perioerative cardiac protection in elderly patients undergoing major gastrointestinal surgery.

Objective:To evaluate the prognostic value of combined detection of serum C-reactive protein(CRP), procalcitonin and lactic acid in elderly patients with community acquired pneumonia(CAP).Methods:Ninety-five elderly CAP patients in the emergency department of Shangqiu First People's Hospital were included as the case group, and 45 elderly healthy people in the emergency department of Shangqiu First People's Hospital were enrolled as the control group.Levels of blood lactic acid, procalcitonin and CRP were compared between the two groups.Meanwhile, blood levels of lactic acid, procalcitonin and CRP were compared between patients with different outcomes in the case group.The receiver operating characteristic(ROC)curve was used to evaluate the prognostic value of CRP, procalcitonin and blood lactic acid in elderly patients with CAP.Results:Compared with the control group, blood levels of lactic acid, procalcitonin and CRP were increased in the case group( t=20.77, 26.03 and 31.27, all P<0.01). During a 12-month follow-up, 13 cases(13.68%, 13/95)died and 82 cases(86.32%, 82/95)survived in the case group.Blood levels of lactic acid, procalcitonin and CRP were higher in the death group than in the survival group( t=25.56, 8.30 and 13.56, all P<0.01). ROC curve analysis showed that the sensitivity and specificity of serum lactic acid, procalcitonin and CRP in predicting the prognosis of elderly CAP patients were 76.92% and 73.17%, 84.62% and 78.05%, and 69.23% and 70.73%, respectively.The sensitivity and specificity of combined detection of the three indicators were 92.31% and 89.02%, respectively, higher than those of the individual indicators. Conclusions:Serum levels of lactic acid, procalcitonin and CRP are increased in elderly patients with CAP.Combined detection of the three indicators can improve the prognostic value and therefore has important clinical significance.

Objective To evaluate the optimum compatibility of nabufine mixed with flurbiprofen for patient-controlled intravenous analgesia (PCIA) after gynecological laparoscopic surgery.Methods A total of 210 patients,aged 18-64 yr,with body mass index of 18-30 kg/m2,of American Society of Anesthesiologist physical status Ⅰ or Ⅱ,scheduled for gynecological laparoscopic surgery under general anesthesia,were divided into 4 groups using a random number table method:sufentanil 2.0 μg/kg+flurbiprofen axetil 2.0 mg/kg group (SF group,n =55),nalbuphine 1.5 mg/kg+flurbiprofen axetil 2.0 mg/kg group (N1 F group,n=49),nalbuphine 2.0 mg/kg+flurbiprofen axetil 2.0 mg/kg group (N2F group,n =55) and nalbuphine 3.0 mg/kg +flurbiprofen axetil 2.0 mg/kg group (N3F group,n=51).PCIA solution was prepared correspondingly after surgery in each group.The PCA pump was set up to deliver a 1 ml bolus dose with a 15-min lockout interval and background infusion at 2.0 ml/h.Nalbuphine 5 mg or sufentanil 5 μg was intravenously injected as a rescue analgesic to maintain visual analogue scale score at rest ＜4 at 48 h after surgery in SF and N1 F-N3F groups.Ramsay sedation scores were recorded on admission to post-anesthesia care unit (T1),at the time of post-anesthesia care unit discharge (T2) and at 6,24 and 48 h after surgery (T3-5).The total pressing times of PCIA in 0-6 h,6-24 h and 24-48 h periods after surgery and requirement for rescue analgesics were recorded.The incidence of adverse reactions such as nausea and vomiting,drowsiness and shivering within 48 h after surgery was also recorded.Results Compared with group SF,the incidence of nausea and vomiting was significantly decreased in N1 F and N2F groups,the requirement for rescue analgesics was significantly decreased,and the total pressing times of PCIA was reduced in N2F and N3 F groups,and Ramsay sedation scores at T3,4 were significantly increased in group N3F (P＜0.05).Compared with group N1 F,the requirement for rescue analgesics was significantly decreased,and the total pressing times of PCIA was reduced in N2F and N3F groups,and the incidence of nausea and vomiting and Ramsay sedation scores at T3,4 were significantly increased in group N3F (P＜0.05).Compared with group N2F,the incidence of nausea and vomiting was significantly increased (P＜ 0.05),and no significant change was found in the requirement for rescue analgesics,total pressing times of PCIA or Ramsay sedation scores in group N3F (P＞0.05).Conclusion Nabufine 2.0 mg/kg mixed with flurbiprofen 2.0 mg/kg is the optimum compatibility when used for PCIA after gynecological laparoscopic surgery.

Objective To find an effective and convenient restraint band for the upper limb of the non-compression side for the patients in the lateral decubitus operation in the Neurosurgery Department. Methods From August 2017 to March 2018, patients in the lateral decubitus operation in the Neurosurgery Department,who from the Second Hospital of Hebei Medical University, were selected as the research objects. The self-made posture restraint belt was made of professional exercise shoulder, forearm sheath, binding band and magic stick. By using random number table produced by SPSS 22.0 edition, 160 patients who underwent lateral decubitus operation in the Neurosurgery Department were randomly divided into the control group and the observation group, with 80 cases in each group. In the control group, the conventional shoulder straps and wrist restraint bands were used, while the self-made lateral decubitus upper limb restraint band was used in the observation group. The differences of the time of lateral decubitus placement, the incidence of pressure sore in the non-compression side of the upper limb and the efficiency of restraint were observed and compared between the two groups. Results The time of lateral decubitus placement (365.97±42.08) s and the incidence of pressure sore in the non-compression side upper limb (10.0%) were higher than those of the observation group[ (302.69± 38.25)s, 1.3%]. The differences were statistically significant (P＜0.05). The efficiency (100.0%) of the non-compression side upper limb restraint in the observation group was higher than that in the control group (91.3%). The difference was statistically significant (P＜0.05). Conclusions The self-made upper limb restraint band for neurosurgery lateral position can effectively expose the surgical field, improve the comfort degree of patients, and improve the efficiency of posture placement and restraint.

Meridian theory plays an important role in the guidance of clinical practice of acupuncture and moxibustion. Since the publication of(), the meridian theory has been developed. In the paper, in view of complex science, the topological properties of acupoint-symptom network were analyzed quantitatively by taking acupoint as node and indication as the connection, such as high clustering coefficient and the small world effect. It was the first time to give the abstraction for the topological proof of the high efficiency information transmission property of acupoint-symptom network meridian system at different times. Its quantitative and digitalized significance was analyzed on the development of meridian theory under the complex scientific background so as to provide a new thought and method for the study of meridian theory and acupuncture modernization.

Probiotics can improve the microecological balance of the body and have special effects in promoting nutrient absorption, controlling intestinal infections, and regulating immune function. However, there are problems such as difficult colonization in the gastrointestinal environment and low oral bioavailability. Bacterial biofilms are organized bacterial cells that adhere to an abiotic or biotic surface and are enclosed in extracellular polymeric substances of exopolysaccharides (EPS), extracellular DNA (eDNA), proteins and lipids, with a three-dimensional spatial structure. Probiotics with the help of bacterial biofilms have obvious advantages over planktonic bacteria in stress resistance, combating pathogens and modulating the host's immune function, which provides a new research idea for the development of probiotics. This paper expounded on the advantages of probiotics with the help of bacterial biofilms, and focused on introducing substances that could promote the formation of probiotic biofilms and the mechanisms, and the safety of probiotic biofilms. Currently, research on probiotic biofilms is still in its infancy, and this paper is expected to provide references for future research in this field.

Objective     To analyze the risk factors for postoperative length of stay (PLOS) after mediastinal tumor resection by robot-assisted non-endotracheal intubation and to optimize the perioperative process. Methods    The clinical data of patients who underwent Da Vinci robot-assisted mediastinal tumor resection with non-endotracheal intubation at the Department of Thoracic Surgery, General Hospital of Northern Theater Command from 2016 to 2019 were retrospectively analyzed. According to the median PLOS, the patients were divided into two groups. The univariate analysis and multivariate logistic regression were used to analyze risk factors for prolonged PLOS (longer than median PLOS). Results    A total of 190 patients were enrolled, including 92 males and 98 females with a median age of 51.5 (41.0, 59.0) years. The median PLOS of all patients was 3.0 (2.0, 4.0) d. There were 71 patients in the PLOS>3 d group and 119 patients in the PLOS≤3 d group. Multivariate logistic regression showed that indwelled thoracic catheter [OR=11.852, 95%CI (2.384, 58.912), P=0.003], preoperative symptoms of muscle weakness [OR=4.814, 95%CI (1.337, 17.337), P=0.016] and postoperative visual analogue scale>5 points [OR=6.696, 95%CI (3.033, 14.783), P<0.001] were independent factors for prolonged PLOS. Totally no tube (TNT) allowed patients to be discharged on the first day after surgery. Conclusion    Robot-assisted mediastinal tumor resection with non-endotracheal intubation can promote rapid recovery. The methods of optimizing perioperative process are TNT, controlling muscle weakness symptoms and postoperative pain relief.
