RESUMO
Objective:To analyze the efficacy and safety of nalbuphine for analgesia in patients with non-mechanical ventilation in intensive care unit (ICU).Methods:From December 2018 to August 2021, a multicenter randomized controlled clinical study was conducted to select non-mechanical ventilation patients with analgesic needs admitted to ICU of four hospitals in Henan Province and Guizhou Province. Patients were randomly assigned to nalbuphine group and fentanyl group. The nalbuphine group was given continuous infusion of nalbuphine [0.05~0.20 mg/(kg·h)], and the fentanyl group was given continuous infusion of fentanyl [0.5~2.0 μg/(kg·h)]. The analgesic target was critical-care pain observation tool (CPOT) score<2. The observation time was 48 hours. The primary endpoint was CPOT score, the secondary endpoints were Richmond agitation-sedation score (RASS), ICU length of stay, adverse events, and proportion of mechanical ventilation. The quantitative data of the two groups were compared by t test or Mann-Whitney U test. The enumeration data were compared by chi square test or Fisher exact probability method. The data at different time points between groups were compared by repeated measures analysis of variance. Results:A total of 210 patients were enrolled, including 105 patients in the nalbuphine group and 105 patients in the fentanyl group. There was no significant difference in baseline data between the two groups (all P>0.05). There was no significant difference in CPOT score between nalbuphine group and fentanyl group at each time point after medication ( P>0.05), the CPOT score of both groups at each time point after medication was significantly lower than that before medication, and the analgesic target could be achieved and maintained 2 hours after medication. There was no significant difference in RASS between the two groups at each time point after medication ( P>0.05), which was significantly lower than that before medication, and the target sedative effect was achieved 2 hours after medication. There was no significant difference in ICU length of stay between nalbuphine group and fentanyl group [5.0(4.0,7.5) d vs. 5.0(4.0,8.0) d, P=0.504]. The incidence of delirium, nausea and vomiting, abdominal distension, pruritus, vertigo and other adverse events in the nalbuphine group was lower than that in the fentanyl group (all P<0.05). There was no significant difference in the incidence of other adverse events such as deep sedation, hypotension and bradycardia between the two groups (all P>0.05). The incidence of respiratory depression in nalbuphine group was not significantly different from that in fentanyl group ( P>0.05), but the proportion of mechanical ventilation was significantly lower than that in the fentanyl group [1.9% (2/105) vs. 8.6%(9/105), P=0.030]. Conclusions:Nalbuphine could be used for analgesia in ICU patients with non-mechanical ventilation. The target analgesic effect could be achieved within 2 hours, and it had a certain sedative effect with a low incidence of adverse reactions.
RESUMO
OBJECTIVE@#To explore the clinical characteristics and genetic etiology of a patient with mental retardation and ejaculatory dysfunction.@*METHODS@#A patient with mental retardation and ejaculatory dysfunction who was admitted to the First Affiliated Hospital of Air Force Military Medical University on November 18, 2021 was selected as the study subject. Clinical data of the patient were collected. Peripheral venous blood samples were collected from the patient and his parents. Whole exome sequencing (WES) was carried out for the patient, and the candidate variant was verified by Sanger sequencing and bioinformatic analysis.@*RESULTS@#The patient, a 26-year-old male, had manifested atypical mental retardation and ejaculatory dysfunction. WES revealed that he has harbored a heterozygous variant of the ARID1B gene, namely c.5776C>T (p.Arg1926X). Sanger sequencing verified that neither of his parents has carried the same variant. The variant has been recorded in the 1000 Genomes, ExAC, gnomAD and ClinVar databases. A search of the dbSNP database suggested that the variant has a population frequency of 0.000 4%. The variant was predicted as deleterious by online software including Mutation Taster, CADD, and MutPred. Analysis with Cluster Omega online software suggested that the amino acid encoded by the variant site was highly conserved among various species. Analysis with PyMOL software suggested that the variant may affect the function of the encoded protein. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG) and ClinGen, the variant was predicted to be pathogenic.@*CONCLUSION@#The c.5776C>T (p.Arg1926X) variant of the ARID1B gene probably underlay the mental retardation and ejaculatory dysfunction in this patient. Above finding has broadened the spectrum of the ARID1B gene variants and provided reference for the diagnosis and treatment of the patient.

Objective:Investigate the prognostic value of high density lipoprotein (HDL) level in patients with streptococcal bloodstream infection.Methods:A total of 698 patients with streptococcal bloodstream infection admitted to the First Affiliated Hospital of Zhengzhou University from January 2015 to December 2019 were enrolled. Serum lipid and other clinical data of patients with positive blood culture within 48 h were recorded. The patients were followed up by telephone from January to March in 2020, and the end-point events were recorded, which were all-cause death 60 days after the diagnosis of streptococcal bloodstream infection. The patients were divided into two groups according to the levels of HDL: low HDL group (HDL ≤0.84 mmol/L) and high HDL group (HDL > 0.84 mmol/L). Univariate and multivariate Cox regression analysis were used to analyze the 60-day prognostic factors of patients with streptococcus bloodstream infection. The receiver operating characteristic (ROC) curve was used to explore predictive value of HDL level for 60-day prognosis of patients. Kaplan-Meier survival curve was used to compare the cumulative survival of patients with different HDL levels.Results:(1) A total of 491 patients were enrolled according to the inclusion criteria, and 461 patients were followed up successfully, with a follow-up rate of 93.89%. There were 373 survival patients and 88 death patients at 60 days, with a 60-day mortality rate of 19.09% (88/461). (2) There were significant differences in age, total cholesterol (TC), HDL, low density lipoprotein (LDL), platelets, albumin, fibrinogen, triglyceride (TG), creatinine, alanine aminotransferase, aspartate aminotransferase, white blood cell, PCT, total bilirubin, direct bilirubin, and respiratory failure and shock between the survival group and death group. (3) Multivariate Cox regression analysis showed that HDL ( RR=1.922, 95% CI: 1.186-3.117, P=0.008), aspartate aminotransferase ( RR=1.953, 95% CI: 1.233-3.094, P=0.004), shock ( RR=15.196, 95% CI: 6.953-33.211, P< 0.001), and respiratory failure ( RR=9.509, 95% CI: 4.232-21.367, P < 0.001) were independent risk factors for 60-day mortality of patients with streptococcal bloodstream infection. (4) The ROC curve analysis showed that HDL alone had a certain value in predicting the 60-day prognosis of patients with streptococcal bloodstream infection. The area under ROC curve (AUC) was 0.602, and the AUC of the combined predictive value of HDL, aspartate aminotransferase, shock and respiratory failure was 0.960, with a sensitivity of 92% and a specificity of 92%. (5) Kaplan-Meier survival curve analysis showed that the cumulative survival rate of patients without endpoint event in the HDL > 0.84 mmol/L group was higher than that in the HDL ≤ 0.84 mmol/L group, but without statistically significant difference (Log-Rank test: χ20.843, P<0.358). Conclusions:Patients with low HDL level of streptococcal bloodstream infection have an increased risk of 60-day death. HDL is an independent risk factor for 60-day death in patients with streptococcal bloodstream infection, and can be used as an indicator to evaluate the prognosis of patients with streptococcal bloodstream infection.

Objective:To investigate the relationship between serum cholinesterase (SChE) level and the prognosis of patients with septic shock (SS).Methods:A total of 594 patients with SS admitted to the First Affiliated Hospital of Zhengzhou University from June 2013 to June 2017 were enrolled. General data such as gender, age, acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) score were recorded as well as routine blood test, procalcitonin (PCT), hepatic function, renal function, coagulation function and blood gas analysis parameters within 48 hours of SS diagnosis. The patients were followed by telephone from September to October in 2019, and the outcome was recorded. The primary outcome was all-cause death 28 days after discharge. The secondary outcomes were all-cause death in intensive care unit (ICU) and 2 years after discharge, and the length of ICU stay. The patients were divided into two groups according to prognosis of 28 days: the survival group and the death group. The clinical data of the two groups were compared. Multivariate Cox regression analysis was used to screen prognostic risk factors of 28 days in patients with SS. The receiver operating characteristic (ROC) curve was used to explore predictive value of liver function parameter SChE for 28-day prognosis of patients with SS. The patients were divided into two groups according to the levels of SChE: the low SChE group (SChE ≤ 4 000 U/L) and the normal SChE group (SChE > 4 000 U/L). Kaplan-Meier survival curves were used to compare the cumulative survival rates without endpoint event of patients with different SChE levels.Results:A total of 385 patients with SS were enrolled according to the inclusion and exclusion criteria, and a total of 356 patients were followed up successfully, with a follow-up rate of 92.5% (356/385). There were 142 survival patients and 214 death patients at 28 days, with a 28-day mortality rate of 60.1% (214/356). There were 116 survival patients and 240 death patients at 2 years, with a 2-year mortality rate of 67.4% (240/356). Compared with the 28-day survival group, the patients in the death group were older and had higher APACHEⅡ score, partial hepatic and renal function parameters, higher level of blood lactate (Lac) and lower levels of white blood cell count (WBC), platelet count (PLT) and SChE with statistically significant differences. Multivariate Cox regression analysis showed that the age [relative risk ( RR) = 1.444, 95% confidence interval (95% CI) was 1.090-1.914, P = 0.010], APACHEⅡ score ( RR = 2.249, 95% CI was 1.688-2.997, P = 0.000), SChE ( RR = 1.469, 95% CI was 1.057-2.043, P = 0.022), and Lac ( RR = 2.190, 95% CI was 1.636-2.931, P = 0.000) were independent risk factors for 28-day mortality of patients with SS. The ROC curve analysis showed that SChE had a weak prognostic value for 28-day prognosis of patients with SS [the area under ROC curve (AUC) was 0.574]. However, the combined predictive value of SChE, APACHEⅡ score and Lac was greater than APACHEⅡ score or Lac alone for prediction (AUC: 0.807 vs. 0.785, 0.697), with a sensitivity of 79.9% and a specificity of 68.5%. Compared with the normal SChE group ( n = 88), the 28-day mortality of patients in the low SChE group ( n = 268) was significantly increased [63.1% (169/268) vs. 51.1% (45/88), P < 0.05], but ICU mortality [59.7% (160/268) vs. 48.9% (43/88)], 2-year mortality [69.8% (187/268) vs. 60.2% (53/88)] or the length of ICU stay [days: 4 (2, 7) vs. 5 (2, 9)] between the two groups showed no statistical significance (all P > 0.05). Kaplan-Meier survival curve analysis showed that the cumulative survival rate without endpoint event of patients in the low SChE group was significantly lower than that in the normal SChE group (Log-Rank test: χ 2 = 5.852, P = 0.016). Conclusions:Increased risk of 28-day mortality in patients with SS whose SChE is below normal. The level of SChE is an independent risk factor for 28-day death in SS patients, and it is one of the indicators to evaluate the short-term prognosis of patients with SS.
RESUMO
Objective To analyze the efficacy and safety of nalbuphine in patients with sedative analgesia in intensive care unit (ICU). Methods A prospective observation was conducted. The adult patients with mild and moderate analgesia in general ICU of the First Affiliated Hospital of Zhengzhou University from January to November in 2017 were enrolled, and they were divided into nalbuphine group and sufentanil group in proper order. The nabobrown group was given 40 mg nabobrown, the sufentanil group was given 0.1 mg sufentanil, both of which were injected with 50 mL normal saline for continuous intravenous infusion in micro-pump. Infusion speed was checked according to pain level. The analgesic target was critical-care pain observation tool (CPOT) score < 2. The change in hemodynamics of patients in both groups were observed, and CPOT score and Richmond agitation-sedation scale (RASS) score were recorded before and l, 3, 5, 12, 24 hours after administration. The analgesic and sedative effects of two drugs were evaluated. Results A total of 141 patients were enrolled, including 71 patients in nalbuphine group and 70 in sufentanil group. There was no significant difference in general data including gender, age, body weight, acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) or pain source, as well as baseline hemodynamics parameter between the two groups. At 1 hour and 3 hours after administration, nalbuphine had no effect on blood pressure, but the heart rate was decreased slightly, while the heart rate and blood pressure of the sufentanil group were decreased obviously. The two drugs could make the heart rate and blood pressure fluctuate obviously with the time of medication, but there was no statistical difference between the two drugs. The two drugs had no significant effect on pulse oxygen saturation (SpO2) during analgesia. The average dosage of nalbuphine was 0.03 (0.02, 0.05) mg·kg-1·h-1in the nalbuphine group, and the patient was satisfied with the analgesic effect until 3 hours after the use of the drug, and CPOT score was significantly decreased as compared with that before administration [1.0 (1.0, 2.0) vs. 3.0 (2.0, 4.0), P < 0.01], and the sedative effect was increased, RASS score was significantly lower than that before administration [0 (0, 1.0) vs. 1.0 (1.0, 2.0), P < 0.01]. No patients in naporphine group were treated with sufentanil due to unsatisfactory analgesia. The average dosage was 0.11 (0.06, 0.14) μg·kg-1·h-1in the sufentanil group, the patient was satisfied with the analgesic effect until 5 hours after administration, and the CPOT score was significantly lower than that before administration [1.0 (1.0, 2.0) vs. 4.0 (3.0, 6.0), P < 0.01], and the sedative effect was significantly increased, RASS score was significantly lower than that before administration [0 (-1.0, 0) vs. 2.0 (1.0, 2.0), P < 0.01]. The scores of CPOT and RASS in the sufentanil group were significantly higher than those of the naporphine group before use, so the decrease in the CPOT and RASS scores of the two drugs was further analyzed, which indicated the decrease in CPOT score of naporphine group was significantly lower than that in sufentanil group from 3 hours on [1.0 (0, 2.0) vs. 2.0 (1.0, 3.0), P < 0.05], and the decrease in RASS score of naporphine group was significantly lower than that in sufentanil group from 1 hour on [0 (0, 1.0) vs. 1.0 (0, 2.0), P < 0.01]. It suggested that naporphine could achieve sustained and stable analgesic effect and avoid excessive sedation caused by sufentanil. Conclusions Naporphine had a sustained and stable analgesic effect on patients with mild and moderate ICU analgesia. The onset time of naporphine was equivalent to sufentanil, and it had a certain sedative effect and less influence on hemodynamics.
RESUMO
Objective To evaluate the efficacy and safety of terlipressin for septic shock.Methods A randomized double-blind placebo-controlled pilot study was carried out in the general ICU of the First Affiliated Hospital of Zhengzhou University from June 1st 2015 to May 31st 2016.The septic shock patients with a mean arterial pressure below 65 mmHg despite adequate volume resuscitation were enrolled.Patients were randomized (random number) to give continuous infusions of either terlipressin[0.6-2.6 μg/(kg·h)] or norepinephrine(7-30 μg/min).Open label norepinephrine or other catecholamines were additionally infused if the mean arterial pressure failed to reach 65 mmHg.Treatment was continued until shock corrected,death or withdrawn from this study.Correcting rate of shock was the primary end point,the secondary end points included open labeled norepinephrine requirements,the 28 d survival rate and adverse events.The quantitative data of the two groups were compared by t test or Wilcoxon rank sum test.The enumeration data were compared by chi square test or Fisher exact probability method,and the survival data were analyzed by Kaplan-Meier method.Results A total of 28 patients were enrolled.The full analysis set was 28,the per-protocol set was 25,and the safety set was 28.The key demographics and baseline characteristics were similar between the two groups(P>0.05).The results for the per-protocol set were followed up.The correcting rate of shock between the two groups were similar at the end of treatment[81.82%(9/11)vs.57.14%(8/14),P=0.190].The open label norepinephrine requirements of the trial group and control group for the 0,6,12,24,48 h time point were 0.661,0.921,1.583,1.241,2.143,1.371,1.071,1.261,0.370,1.001 μg/(kg·min),respectively with no significant difference(P>0.05).The 28 d survival rate of the trial group and control group were 63.64%(7/11)and 50.00%(7/14) respectively with no statistical significance(P>0.05).There was no significant difference in 28 d survival analyzed using Kaplan-Meier plot between two groups(P=0.470).There were two patients with ischemia of fingers,one patient with hyponatraemia and one patient with ischemia of intestine accompanied by hyponatraemia occurred after treatment with terlipressin,and one patient with isehemia of fingers occurred after treatment with norepinephrine.The incidence of adverse event for the trial group and control group were 30.77%(4/13) and 6.67%(1/15) with no significant difference(P=0.122).Conclusions Terlipressin is an effective agent for treating septic shock.The total adverse event rate of terlipressin was similar to that ofnorepinephrine.
RESUMO
Objective To investigate the effects of artesunate (Art) on cell proliferation, apoptosis, nuclear factor (NF)-κB and monocyte chemotactic protein 1 (MCP-1) expressions induced by high glucose in rat renal mesangial cells (HBZY-1), and the mechanism thereof. Methods HBZY-1 cells were cultured and divided into normal glucose group (5.6 mmol/L), high glucose group (25 mmol/L) and high glucose with different concentrations of Art (10 mg/L, 20 mg/L, 30 mg/L) groups. MTT assay was used to detect the cell proliferation after 48 h. The apoptotic rate was evaluated by flow cytometry with Annexin V-FITC/PI double stains. The protein levels of NF-κB and MCP-1 in the cell culture supernatant were determined using ELISA. Results High glucose induced apoptosis and proliferation in HBZY-1 cells, and the expressions of NF-κB and MCP-1 in the supernatant were also increased (P<0.05). After treatment with Art, the proliferation was obviously abolished, and the apoptosis was increased, and the expressions of NF-κB and MCP-1 in the supernatant were decreased in HBZY-1 cells. The effects of Art showed a dose-dependent manner (P<0.05). Conclusion Artesunate treatment can reverse the effect of high glucose in HBZY-1 cells in a dose-dependent manner, which may provide a new therapeutic strategy for diabetic nephropathy.
RESUMO
ObjectiveTo evaluate the effect of high frequency oscillation ventilation (HFOV) vs. conventional mechanical ventilation (CV) on the treatment and prognosis of adult patients with acute respiratory distress syndrome (ARDS).Methods Published articles concerning randomized controlled trials (RCTs) about the effect of HFOV vs. CV on the prognosis of adult patients with ARDS published before May 2014 were retrieved from PubMed, EMBase, Cochrane central registry of controlled trials, CNKI and Wanfang Data. The mortality and data of physiological parameters were analyzed with STATA 12.0, and the mortality rate was also analyzed by trial sequential analysis with TSA 0.9, and the line chart was drawn with Microsoft Office Excel 2003.Results Seven trials with 1 731 patients met the criteria, all of them recorded the physiological parameters data, and mortality rate was mentioned in 6 trials (1 705 patients). Compared with CV, HFOV did not show any statistically significant beneficial effects on mortality [relative risk (RR) = 0.93, 95% confidence interval (95%CI) = 0.70-1.24,P = 0.63], and other clinical outcomes, including survival without mechanical ventilation (RR = 1.05, 95%CI = 0.72-1.54,P = 0.80), survival on mechanical ventilation (RR = 1.23, 95%CI = 0.65-2.35,P = 0.52), or treatment failure (RR = 0.89, 95%CI = 0.50-1.56,P = 0.67). The risk factors of adverse events including hypotension (RR = 0.89, 95%CI = 0.07-10.99,P =0.93), acidosis (RR = 1.05, 95%CI = 0.43-2.56,P = 0.91), and air leakage from ventilator (RR = 0.74, 95%CI = 0.31-1.80,P =0.51) were similar. But the physiologic parameters of patients and parameters of ventilator in HFOV group, including oxygenation index, positive end-expiratory pressure, tidal volume, mean airway pressure, arterial pH, partial pressure of arterial carbon dioxide, fraction of inspired oxygen, ratio of partial pressure of arterial oxygen to fraction of inspired oxygen, were better than those in the CV group. Methods adapted from formal interim monitoring boundaries applied to cumulative Meta-analysis showed that the evidence failed by a considerable degree to meet the standards for forgoing studies, and the necessary sample was 3 874 patients. Trial sequential analysis also showed that the accumulatedZ-score did not cross the traditional boundary (P = 0.05) and interim monitoring boundaries. This result indicated that there was no significant difference between CV and HFOV on mortality before the number of needed sample reached (3 874 cases). We could not get a definitive conclusion with current evidences.ConclusionsCompared with CV, the use of HFOV in ARDS was not associated with a significant reduction in mortality. But the physiologic parameters of patients in HFOV group were better than those in the CV group. More RCTs are needed to draw a definitive conclusion.
RESUMO
[ABSTRACT]OBJECTIVETo investigate the diagnosis, treatment method, key points of operation, and postoperative complications of high-risk esophageal foreign body.METHODSA retrospective analysis of 41 cases of high-risk esophageal foreign body from January 1996 to December 2014. After adequate preparation, the foreign body was removed via esophageal endoscope under general anesthesia.RESULTSThe foreign bodies in 41 patients were removed via esophageal endoscope once or twice. Two cases suffered postoperative subcutaneous emphysema, that may be a result of a small perforation in esophagus. Emphysema was disappeared by fast, rehydration and anti-infection for 6 to 8 days, and other serious complications did not occur.CONCLUSIONMost high-risk esophageal foreign bodies can be removed through rigid esophagoscopy. Some of the foreign bodies of the patients were difficult to remove, some patients were presented with mediastinal emphysema and pneumothorax due to esophageal perforation, and some foreign body stuck in oesophagus so long to cause esophageal mucosa ulcer. In these conditions, foreign bodies should be removed by lateral neck incision or thoracotomy.
RESUMO
Objective Based on the health standards for arsenic in drinking water recommended by WHO (0.01 mg/L) and adopted by decentralized rural water supply in China (0.05 mg/L), to explore the conditions of arsenic metabolism and levels of methylation in population consuming drinking water with different concentrations of arsenic. Methods Three hundred and forty-eight adults in Shanxi exposed to different concentrations of arsenic(≥0.05 mg/L, ≥0.01-0.05) in arsenic species , TAs , first methylation ratio (FMR) and SMR in lower exposure group and the control group. In higher exposure group, the FMR of adults aged over 60 years was significantly higher than that in groups of 18-39 years old and 40-49 years old (P0.05). Conclusion In higher exposure group, the 2nd reaction of the metabolic pathway is more active in female than that in male, and arsenic methylation capacity of the higher age group arise. No significant effects of gender and age on arsenic methylation capacity is found among population exposed to drinking water with lower level of arsenic.
