Objective:To evaluate effects of different medication forms of dexmedetomidine on perioperative cognitive function in elderly patients undergoing radical operation of gastric carcinoma, and Ramsay sedation score.Methods:A total of 150 patients aged 65 years and 75 years scheduled for elective radical operation of gastric carcinoma from December 2018 to December 2019 in Shanxi Provincial Cancer Hospital were enrolled, and they were divided into 3 groups according to random number table method: different medication forms of dexmedetomidine groups (group A, group B) and the control group (group C), 50 cases in each group. The patients in group A and group B continued to pump dexmedetomidine at a rate of 0.5 μg·kg -1·h -1 and 0.3 μg·kg -1·h -1 respectively for 15 min before induction of anesthesia. And the patients in group C were given intravenous pumping of an equal volume of 0.9% NaCl for 15 min. Subsequently, patients in group A and group B received continuous intravenous infusion of 0.3 μg·kg -1·h -1 for 30 min before the end of operation, the patients in group C received 0.9% NaCl infusion of equal volume until the end of operation. The cognitive function of the patients was measured by using the Monterey cognitive assessment scale (MoCA) the day before surgery and on day 1,3 and 7 after surgery, and the incidence of perioperative neurocognitive disorder (PND) was counted. Ramsay sedation score at 30 min, 24 h and 48 h after surgery was compared among the three groups. Results:There were 3 patients in group A and 3 patients in group C were excluded because they were transferred to ICU due to serious postoperative complications. There were significant differences in MoCA score among the three groups on day 1, 3, 7 after operation (all P < 0.01); MOCA score of group A, B and C on day 7 after operation was (26.9±0.7) scores, (26.6±1.0) scores, (26.3±1.2) scores, respectively, and the difference between group A and group C was statistically significant ( P < 0.01). The incidence of PND among the three groups on day 1, 3, 7 after surgery had statistically significant differences (all P < 0.05), and the incidence of PND in group A was lower than that in group B and C (all P < 0.05). Ramsay sedation score among the three groups at 30 min and 24 h, 48 h after operation showed statistically significant differences (all P < 0.01), and that in group C was lower than that in group A and group B, and the differences were statistically significant (all P < 0.01). Ramsay sedation score at 24 h after operation in group A was high than that in group B and group C (all P < 0.01). Conclusions:Dexmedetomidine assisted with anesthesia can reduce the incidence of PND in elderly patients undergoing radical operation of gastric carcinoma and enhance the sedative effect. What's more, the most obvious effect is the infusion of 0.5 μg·kg -1·h -1 before anesthesia induction.

Objective Our research aimed to investigate the efficacy and the nursing characteristics of allogenic bone marrow mesenchymal stem cell (BM-MSCs) transplantation in HBV related acute-on-chronic liver failure (ACLF) patients.Methods A total of 91 HBV related ACLF patients were enrolled,among whom 45 patients received allogenic BM-MSCs transplantation via peripheral vein and other 46 patients received medical treatment only.We assessed the 12-week survival rates and the variation of model for end liver disease (MELD) score.Besides,we administrated comprehensive nursing for these patients in different stages of the transplantation.Results The cumulated survival of patients received BM-MSC transplantation was 75.6％,which was higher than the control group (54.5％).The level of total bilirubin and International Normalized Ratio (INR) had greatly improved.41 of 45 patients passed through perioperative period safely,without any severe adverse events.11 patients died due to exacerbation of liver failure,among whom 3 happened in perioperative period.But none was related with the operation.Conclusions Allogenic BM-MSCs transplantation can improve the survival rate of HBV related ACLF patients.The psychological nursing pre-operation,skilled operation,intensive care and observation post operation were beneficial to the patients' recovery after transplantation.

Objective To compare the clinical efficacy of different doses of ultrafine extracted granule preparation (EGP) and traditional herbal decoction (THD) of Li Zhong Tang in treatment of epigastric pain. Methods Sixty cases of epigastric pain patients in accordance with the diagnostic criteria of deficiency and cold pattern of spleen and stomach in TCM were randomly divided into THD group, 1/3 dose group and 1/5 dose group, and were given THD, 1/3 dose of ultrafine EGP and 1/5 dose of ultrafine EGP, respectively. The clinical efficacy of the three groups after one course of medication was comparatively analyzed. Results There were no significant differences in age, course of disease, symptom score before treatment, epigastric pain efficacy and syndrome curative effect among the three groups, the differences had no statistical significance (P>0.05). The severity, frequency and duration of epigastric pain were all reduced in the three groups, with significant differences between before and after treatment (P<0.05). Conclusion There are no significant differences in the clinical efficacy on epigastric pain among THD, 1/3 dose of ultrafine EGP and 1/5 dose of ultrafine EGP. In addition, the effect of 1/3 dose group is very close to the THD group.

Objective To explore the therapeutic effect and application value of the self-made spinal positioning equipment and percutaneous pedicle screw fixation system in the treatment of thoracic and lumbar fracture. Methods To determine the fractured vertebra and pedicle screws entrance point with spinal positioning equipment, 67 patients with thoracic and lumbar fractures were performed percutaneous pedicle screw fixation by using self-made percutaneous pedicle screw fixation system. By contrasting the perioperative indicators, and imaging indicators, to evaluate the therapeutic effect and application value of the system. Results For the spinal positioning equipment, the location time were (15.85±2.45) min and the location accuracy were 95.03%±3.27%. But for the open reduction internal fixation, the location time were (35.46±5.39) min and the location accuracy were 94.02%±2.95%. There was no significant difference in location accuracy, but were significant differences in location time (P＜0.05). Percutaneous pedicle screw fixation had the same effect on three sides with open reduction internal fixation in vertebral height restore,kyphosis deformity and correction and lumbar spinal stenosis's correction. The perioperative indicators of the preoperative and postoperative grope had significant difference (P＜0.05). There were significant differences in all perioperative indicators between the percutaneous pedicle screw fixation and the open reduction internal fixation (P＜0.05). Conclusion The spinal positioning equipment is helpful to determine the fractured vertebra and pedicle screws entrance point accurately and reduce the radiation. The percutaneous pedicle screw fixation system has the advantage of convenient manipulation and accurate implantation. The system can not only reduce surgical damage and post-operation reaction but also make patients recover quickly and face less complications.
