Objective To analyze the correlation of discomfort experience and factual recollection (FR) in patients of intensive care unit (ICU). Methods Fifty-five ICU patients and 63 ward patients par-ticipated in the study. Standardized questionnaires were used to evaluate all patients" FR and the results underwent analysis. Results The prevalence of recollection of any type of discomfort in the ICU patients was 64%. The presence of an endotracheal tube, pain and hallucinations were identified as sources of dis-comfort.The median score for FR in the ICU patients was 7.25. The median score for FR in the ward pa-tients was 13.50. The difference between them was highly significant (t =3.34, P < 0.01 ). Logistic analysis revealed that discomfort, especially discomfort caused by the presence of an endotracheal tube, pain and hallucinations, was positively related to FR, 0R95%CI (1.2～2.1), P < 0.01. Conclusions The presence of an endotracheal tube, pain and hallucinations were most frequently reported as sources of discomfort in ICU patients and their memory was often impaired. FR and recollection of discomfort appear to be related significantly in ICU patients.

Objective:To study the clinical application of laparoscopic combined with multi-video debridement in treatment of complicated infectious pancreatic necrosis (CIPN).Methods:The clinical data of 34 patients with CIPN who were treated at the Department of General Surgery, Xuanwu Hospital, Capital Medical University from August 2017 to December 2019 were retrospectively studied. Based on the different video methods used, these patients were divided into 3 groups: the laparoscopic combined with intraoperative ultrasound group, the laparoscopic combined with choledochoscopy group and the laparoscopic group. The number of operations, operation time, blood loss, postoperative complication rates, mortality rates and total length of hospital stay were compared.Results:There were 13 patients in the laparoscopic combined with intraoperative ultrasound group, with age of (56.4±13.4) years. There were 7 patients in the laparoscopic combined with choledochoscopy group, with age of (48.0±8.4) years. There were 14 patients in the laparoscopic group with age of (51.4±15.6) years. The number of operations of the laparoscopic combined with intraoperative ultrasound group, the laparoscopic combined with choledochoscopy group and the laparoscopic group were (2.2±1.1), (1.6±0.8), (2.9±1.4), respectively. The number of operations of the laparoscopic combined with choledochoscopy group were significantly less than that of the laparoscopic group ( P<0.05), but there were no significant differences among the other groups ( P>0.05). The operation time of the laparoscopic combined with intraoperative ultrasound group, the laparoscopic combined with choledochoscopy group and the laparoscopic group were (70.5±22.9) min, (65.7±19.9) min, (51.5±15.4) min, respectively. The operation time of the laparoscopic combined with intraoperative ultrasound group was significantly longer than that of the laparoscopic group ( P<0.05), but there were no significant differences among the other groups ( P>0.05). There were no differences in blood loss, postoperative complication rate, mortality rates and total lengths of hospital stay among the three groups ( P>0.05). Conclusion:Laparoscopic combined with multi-video debridement after making full use of the advantages of each of the video methods, can be used to improve treatment outcomes of patients with CIPN.

BACKGROUND: It is discovered by administrating different emetics to vomiting animals, like cats, that there are a large amount of Fos positive neuronal expressions in the arc region from nucleus of solitary tract, lateral tegmentum to ventrolateral area. And it has been viewed that the arc region from area postrema, nucleus of solitary tract to ventrolateral reticular structure is the main emetic region. Whether do the non-vomiting animals reflect in response or not after emetic injection?OBJECTIVE: To observe the distribution of Fos positive neurons in relevant emetic regions of brain and spinal cord in rats after abdominal injection of emetic, cisplatin.DESIGN: Randomized controlled experiment based on animals.SETTING: Neural Physiological Research Room of Life Science College in Hebei Normal University and Physiological Room of Basic Medicine Institute in Hebei Medical University.MATERIALS: The experiment was performed in Neural Physiological Research Room of Life Science College in Hebei Normal University and Physiological Room of Basic Medicine Institute in Hebei Medical University from March to August 2003. Twelve SD male rats were employed, body weighted varied from 220 to 250 g, of clean-grade. They were randomized into experimental group of 6 rats and the control of 6 rats.INTERVENTIONS: In experimental group, the emetic, cisplatin, was injected abdominally 10 mg/kg. In the control, the physiological saline of same dose was injected. Afterwards, the activity changes in rats were observed at room temperature, quiet and light-avoided environment. Six hours later, the brain tissue was collected for frozen continuous sectioning. Immunohistochemical staining method was used to observe the distribution of Fos positive neurons in brainstem and forebrain nuclei and to count positive cell.MAIN OUTCOME MEASURES: ① Behavior observation in rats after emetic injection. ② Counts of Fos positive cell in relevant regions of brain in rats.RESULTS: Twelve rats all entered result analysis. ① In 20 minutes after injection, the rats in both groups were in tranquilizing state, lying prone with body curled, almost without any movement. In 60 minutes after injection, the rats in the control were recovered to normal, free of eating or drinking. The rats in experimental group were in prone-lying state with body curled. They rose up or shook the heads occasionally, and they breathed fast and uneven.In 2 hours after injection, in experimental group, the rats were still in abdominal prone tightly in the cage, with heads lowed and irregular shaking of noses. In 5 hours, the rats in experimental group began standing up and moving, with normal breathing, but they still did not eat or drink. ② Fos positive neurons in solitary tract, area postrema and lateral parabrachial nucleus and paraventricular nucleus, supraoptic nucleus and arc nucleus in hypothalamus (64.3 ±9.6, 83.4 ±15.0, 148.8 ±19.9, 80. 2 ± 11.8, 20.7 ±3.8, 86. 6 ± 10.8) were remarkably higher than those in the control(56. 2 ±6.3,73.5±9.9,136.9±17.8,66. 1±10.3,17.3±3.4,78.8±10.5).CONCLUSION: Emetics induce discomforts in internal organs of rats, due to which, there probably exist emetic regions similar to vomiting animals in central neural system. But it is probably lack of vomiting-related adjusting mechanism. Emetics irritate the increase of Fos positive neurons in relevant regions in the brain of rat, which suggests that there exist relevant neural chemical pathways similar to nausea in the brain of non-vomiting rats.

Objective:To explore the epidemiological characteristics and clinical outcomes of patients diagnosed with novel coronavirus (COVID-19) pneumonia (NCP), and to provide clinical reference for subsequent epidemic prevention and control.Methods:The pathogenesis, clinical characteristics and clinical outcomes of 62 patients with imported novel coronavirus COVID-19 pneumonia in Qingdao area from January 21, 2020 to April 6, 2020 were analyzed.Results:There were 24 males and 38 females, aged from 5 to 91 (52.5±15.7)years. Among them, 31 cases (31/62, 50%) were family cluster disease, 11 cases (17.74%) were nosocomial cross infection, 14 cases (22.58%) came back from Wuhan to Qingdao and community contact infection, and 6 cases (9.68%) were imported from abroad. The longest time from fever to diagnosis was 26 days. Clinical classification: 40 cases were mild, 13 were general, 7 were severe, 2 were critically ill. 61 cases were discharged from hospital, and 1 was dead. The clinical cure rate was 98.39%. The average stay was (18.5±4.8)days. All patients were treated combined with Chinese medicine on the basis of symptomatic treatment.Conclusions:The clinical symptoms of imported NCP are relatively mild, and mild cases were more, the recovery rate was higher. The intervention strategy of traditional Chinese medicine is conducive to rehabilitation. The external input cases and symptomless infected patients are important for epidemic situation in the future.

Objective:To evaluate the clinical outcomes of patients with single spinal metastasis of thoracic, lumbar or sacral vertebra treated with microwave ablation in situ.Methods:For 28 patients with single spinal metastasis of thoracic, lumbar or sacral vertebra, detailed and personal surgical plans were carried out. Instead of en bloc resection, hyperthermia ablation in situ was performed followed by strengthening procedures under the guidance of G-arm fluoroscopy machine. Intraoperatively, spinal cord and nerve root were properly protected. The bone defects were reconstructed by bone cement after the diseased lesions were revomed. All patients were followed up for almost 1 year postoperatively. During follow-up, X-ray and MRI images were obtained, and the level of pain and neurologic outcomes were also examined.Results:All 28 patients successfully received microwave ablation in situ. The average ablation time was approximately 8 minutes and the average amount of bone cement implanted was approximately 10.5 ml. The pain scores of digital pain classification before and 3 months after operation were 7.86±1.58 and 3.07±1.89( P<0.05). The postoperative neurological function of 22 patients was improved than that before operation. No significant changes were observed in 5 patients. The neurological function of the affected limb was relieved, whereas the symptoms of the healthy limb were slightly worse in the remaining case. Conclusions:Microwave ablation in situ is a feasible and effective surgical method for single spinal metastasis of thoracic, lumbar or sacral vertebra. It might possess many advantages, such as clear surgical field, smaller incisions, less bleeding, and safe margins during the operations. Further more, it could significantly relieve pain, restrict tumor growth, and improve the quality of life of patients. It is an innovative and distinctive therapeutic alternative for single spinal metastasis, which deserves widespread application.

OBJECTIVE:To study inhibitory effects of propofol on PC12 cells injury induced by glutamic acid via mitogen-acti-vated protein kinase/extra-cellular regulated kinase (MAPK/ERK) signal pathway. METHODS:PC12 cells were randomized into normal control group,model group(10 mmol/L glutamic acid),propofol low-concentrations,medium-concentrations and high-con-centrations groups(12.5,25,50 μmol/L+10 mmol/L glutamic acid). The optical density of cells,cell apoptosis,the phosphoryla-tion of ERK1/2 and the expression of c-fos,Bax,Bcl-2 were detected after treated with relevant medicine for 48 h. RESULTS:Compared with normal control group,optical density of cells,the phosphorylation of ERK1/2 and Bcl-2 decreased in model group (P<0.01);apoptotic rate,the expression of c-fos and Bax increased (P<0.01). Compared with model group,optical density of cells,the expression of Bcl-2 and the phosphorylation of ERK1/2 increased in propofol group (P<0.01);apoptosis rate,the ex-pression of c-fos and Bax decreased (P<0.05 or P<0.01). There were statistical significant between the different concentrations (P<0.01). CONCLUSIONS:Propofol can inhibit the apoptosis of PC12 cells induced by glutamic acid,which is associated with the up-regulation of ERK1/2 phosphorylation.
