Objective To investigate the effects of controlled hypotension induced with sodium nitroprusside (SNP) or nicardipine on hemodynamics during hip operation and postoperative hepatic and renal function.Methods Twenty ASA Ⅰ or Ⅱ patients aged 20-70 yrs weighing 50-80 kg scheduled for total hip replacement or open reduction and internal fixation of fracture of acetabulum were randomized to receive either SNP (group Ⅰ ) or nicardipine (group Ⅱ ) for induced hypotension during operation. Each group included 10 patients. Radial artery and right internal jugular vein were cannulated for BP and CVP monitoring. The probe of Hemo-Sonic ?100 esophageal supersonic hemodynamic monitor (Arrow U.S.A) was placed in the esophagus and fixed when best signal was obtained. ECG, hemodynamics including MAP, HR, CVP, CO and other parameters, SpO2 and PetCO2 were continuously monitored. Anesthesia was induced with propofol 2 mg?kg-1 , fentanyl 2-3 ?g? kg-1 and vecuronium 0.1 mg?kg-1 and maintained with 1.5% isoflurane and continuous infusion of propofol ( at 4-6 mg?kg-1 ?h-1 ) and intermittent i.v. boluses of vecuronium after tracheal intubation. MAP was reduced to 55-65 mm Hg with SNP (at a rate of 0.5-8.0 ?g?kg-1?min-1 ) or nicardipine (at 1.0-8.0 ?g?kg-1 ?min-1 ) . Intraoperative blood loss and blood transfusion and postoperative drainage from the wound were measured and recorded.Hemodynamic parameters were recorded before hypotension and 15, 30 and 60 min after start of induced hypotension and 15 and 30 min after recovery from hypotension. Hepatic and renal functions were measured before and after operation using total bilirubin, AST, ALT, BUN and creatinine. Results The two groups were comparable with respect to sex ratio (M/F) , age, height, body weight, duration of induced hypotension and operation. MAP and systemic vascular resistance (SVR) were significantly reduced and tachycardia developed during hypotension in both groups. The left ventricular ejection time was significantly prolonged and aortic blood flow (ABF) and cardiac output (CO) were significantly increased and CVP was lowered during hypotension as compared to the baseline values in SNP group. BUN was significantly reduced after operation ( P

Objective To explore the effects of Chinese herbal compound Tangbikang on the expressions of p38 MAPK of sciatic nerve and plasma TNF-α in diabetic rats. Methods Ten of the sixty male SD rats were selected randomly as normal group, and the rest were fed with high-fat diet and low-dosage STZ was used to induce type Ⅱdiabetic rat models. Model rats were randomly divided into model group, mecobalamine group and Tangbikang low-, medium-, and high-dosage groups, 10 rats in each group. Each medication group was intervened with relevant medicine. Rat unilaterals sciatic nerves were taken after 16 weeks. The content of TNF-α in plasma was determined by radioimmunoassay. Western blot method was used to detect the expressions of p38 and p-p38 MAPK protein of sciatic nerve. Results Compared with normal group, the expressions of p38 and p-p38 protein and content of TNF-αin model group significantly increase (P<0.05, P<0.01). Compared with the model group, the expressions of p-p38 protein and the content of TNF-α significantly decreased after medicine intervention in different doses Tangbikang groups and mecobalamin group (P<0.05, P<0.01). The expression of p38 protein in Tangbikang high-dose group significantly decreased (P<0.05), with statistical significance (P<0.05). Conclusion Tangbikang can reduce the expression of p38 and p-p38 MAPK protein of the rat sciatic nerve, and reduce the content of TNF-α protein in rat plasma, which may be one of the effective targets of neuroprotection and abirritation of diabetic peripheral neuropathy.

Objective:To explore the effect of group psychological and behavioral intervention in elderly patients with depression.Methods:From January 2017 to November 2020, 106 elderly patients with depression admitted to the Third People's Hospital of Fuyang were selected as the research object by convenience sampling method. According to the random number table, the patients were divided into the experimental group and the control group, 53 cases in each group. The control group was given routine psychological and behavioral intervention, and the experimental group received group psychological and behavioral intervention on this basis for two weeks. The scores of the Chinese version of the Depression Self-Stigma Scale (DSSS) and the Chinese version of the Personal and Social Performance Scale (PSP-CHN) were compared between the two groups before and after the intervention.Results:A total of two patients in the experimental group and four patients in the control group dropped out. Finally, 51 patients in the experimental group and 49 patients in the control group were included. After two weeks of intervention, the Chinese version DSSS dimension scores and total scores of the experimental group were lower than those of the control group, and the total score of PSP-CHN was higher than that of the control group, and the differences were statistically significant ( P<0.05) . Conclusions:Group psychological and behavioral intervention can help reduce self-stigma in elderly patients with depression and improve their personal and social functions.

Objective:To explore the effect of intensive nursing risk control in schizophrenic (SP) patients undergoing modified electroconvulsive treatment (MECT) .Methods:Using the convenient sampling method, total 202 SP patients who received MECT at the Department of Psychiatry in Fuyang Third People's Hospital from January 2019 to January 2021 were selected as the research objects. According to the random number table, the patients were divided into the observation group and control group with 101 cases each. Patients in the control group received routine care, while patients in the observation group underwent intensive nursing risk control on this basis. The anesthesia cooperation during MECT and the incidence of adverse reactions during anesthesia resuscitation were compared between the two groups.Results:The anesthesia cooperation of the observation group during MECT was better than that of the control group, and the difference was statistically significant ( P<0.05) . The total incidence of adverse reactions during anesthesia resuscitation in the observation group was lower than that in the control group, with a statistically significant difference ( P<0.05) . Conclusions:Intensive nursing risk control can improve the anesthesia cooperation of SP patients during MECT and reduce the occurrence of adverse reactions during anesthesia resuscitation, which is worth promoting in clinical practice.

Objective: To analyze the mutation of target genes in extranodal natural killer/T-cell lymphoma (ENKTL) by using nextgeneration sequencing, and to explore its relationship with prognosis and clinical characteristics, as to provide evidence for the pathogenesis, clinical diagnosis and targeted therapy of ENKTL. Methods: According to previous literature reports, the genes whose mutations can affect the development of lymphoma were selected as the target genes for this study. 29 patients with ENKTL, who were newly diagnosed at the Fourth Hospital of Hebei Medical University from August 2010 to October 2018, were selected for this study. The mutation of 9 target genes in the specimen was detected by thenext-generationsequencingtechnology.Therelationshipsamongclinicalfeatures,diseaseprognosisandmutationofthetargetgeneswereanalyzedbySPSS21.0statisticalsoftware.Results： ：Ninetargetgenes were were screened. AT-rich interactive-domain 1A(ARID1A) gene showed the highest mutation rate in ENKTL (10 cases, 34.48%) followedbylysinemethyltransferase2D(KMT2D)gene(31.03%)andtumorprotein P53 (TP53) gene (24.13%). Kaplan-Meier survival analysis showed that the overall survival of ENKTL patients with KMT2D gene wild type was significantly better than patients with KMT2D gene mutation (P=0.006). The KMT2D gene mutation was found to besignificantlyrelatedtoclinicalstage,CRP,albumin,lymphocyte count and Ki67 expression in ENKTL patients (all P<0.05). COX regression analysis showed that KMT2D gene mutation was an independent adverse prognostic factor (P<0.05). Conclusion: The KMT2D gene has a high mutant frequency in ENKTL and is associated with patients’prognosis, suggesting that KMT2D gene plays an important role in the initiation and development of ENKTL. It could be used as a clinical therapeutic target for ENKTL.

Developmental exposure to bisphenol A (BPA), an endocrine-disrupting contaminant, impairs cognitive function in both animals and humans. However, whether BPA affects the development of primary sensory systems, which are the first to mature in the cortex, remains largely unclear. Using the rat as a model, we aimed to record the physiological and structural changes in the primary auditory cortex (A1) following lactational BPA exposure and their possible effects on behavioral outcomes. We found that BPA-exposed rats showed significant behavioral impairments when performing a sound temporal rate discrimination test. A significant alteration in spectral and temporal processing was also recorded in their A1, manifested as degraded frequency selectivity and diminished stimulus rate-following by neurons. These post-exposure effects were accompanied by changes in the density and maturity of dendritic spines in A1. Our findings demonstrated developmental impacts of BPA on auditory cortical processing and auditory-related discrimination, particularly in the temporal domain. Thus, the health implications for humans associated with early exposure to endocrine disruptors such as BPA merit more careful examination.
