Objective:To understand the basic information such as age,job title,and education of rehabilita-tion therapists in the Grade Ⅲ public psychiatric hospitals in China,and provide fundamental data for the construc-tion of the mental health rehabilitation talent team.Methods:The staffing of rehabilitation therapists in 43 Grade Ⅲpublic psychiatric hospitals in eastern,central,and western regions of China were investigated.The age,education,job title,professional relevance and inter-regional differences of the rehabilitation therapists were statistically ana-lyzed.Results:There were 197 rehabilitation therapists in 43 hospitals surveyed.The age distribution was mainly in 20-30 and 30-40 years old with a bachelor's degree and junior,and more than half of the personnel had their first academy degree related to the rehabilitation profession.The differences in age,education,job title were statistically significant in the eastern,central and western regions.Conclusion:The overall quality of the rehabilitation therapists in China's Grade Ⅲ public psychiatric hospitals is relatively high,and the age structure is reasonable.However,the proportion of senior professional titles is relatively low.Therefore,it is necessary to focus on talent training and the establishment of promotion systems in the future,in order to improve the professional development space and level of the entire industry.

Changes of brain oxygenated hemoglobin concentration in adolescent patients with depression under speech fluency task / 中华行为医学与脑科学杂志

Objective:To explore the characteristics and differences of oxygenated hemoglobin responses in different brain regions in adolescent depressive disorder patients and healthy adolescents during speech fluency task based on functional near-infrared spectroscopy imaging.Methods:From March 2021 to June 2021, twenty-nine adolescents with depression(depressed group) and 26 healthy adolescents(normal group) were enrolled. The severity of depression was assessed by Hamilton depression scale, and the speech fluency task was performed by functional near-infrared spectroscopy brain imaging, and the relative concentrations of oxyhemoglobin in the prefrontal and bilateral temporal lobes were measured.SPSS 26.0 statistical software was used for data analysis, chi-square test was used for gender count data. The t-test was used for comparison of two groups. The measurement data that did not conform to normal distribution were compared between the two groups by Mann-Whitney U test. Results:In the speech fluency task, there was no significant difference in the concentration of oxygenated hemoglobin in prefrontal and left temporal between the depressed group and the normal group (both P>0.05); the oxygenated hemoglobin concentration in the right temporal lobe(-9.179(-22.231, 4.789)) of depressed group was significantly lower than that of the normal group (12.754(-9.438, 35.008)), and the difference was statistically significant ( U=538.00, P<0.05). The oxygenated hemoglobin concentration in right temporal lobe of depressed group had no correlation with the score of Hamilton depression rating scale ( r=0.092, P>0.05). Conclusion:The right temporal lobe function of adolescent depression patients is lower than that of healthy controls during speech fluency tasks, which provides a basis for study of the relationship between depression and some cognitive sensitivity impairment and the function of right temporal lobe.

Objective:To investigate the dose-effect relationship of alfentanil inhibiting cardiovascular responses to tracheal intubation when combined with midazolam and etomidate.Methods:American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱ patients of either sex, aged 18-64 yr, with body mass index<32 kg/m 2, undergoing elective operation under general anesthesia with endotracheal intubation, were enrolled in this study.Midazolam 0.025 mg/kg was intravenously injected for adequate sedation, and 5 min later mean arterial pressure and heart rate were recorded for 3 consecutive times at an interval of 3 min, and the mean value was calculated and served as the baseline value.Etomidate 0.3 mg/kg was intravenously injected, and alfentanil and rocuronium 0.6 mg/kg were intravenously injected when bispectral index value < 60, and then 1.4 min later tracheal intubation was performed.The dose of alfentanil was determined by the Dixon′s up-and-down method.The initial dose of alfentanil was set at 20 μg/kg.The dose of alfentanil in the next patient was determined according to the development of cardiovascular responses to tracheal intubation, and the ratio between the two successive doses was 1.0∶1.1.The cardiovascular response was defined as as positive when the maximum value of mean arterial pressure or heart rate increased by ≥20% of the baseline value within 2 min after endotracheal intubation.Probit method was used to determine the ED 50, ED 95 and 95% confidence interval of alfentanil inhibiting cardiovascular responses to tracheal intubation. Results:When combined with midazolam and etomidate, the ED 50 (95% confidence interval) of alfentanil inhibiting cardiovascular responses to tracheal intubation was 21.343 (19.105-24.516) μg/kg, and the ED 95 (95% confidence interval) was 25.043 (22.983-48.983) μg/kg. Conclusions:When combined with midazolam and etomidate, the ED 50 and ED 95 of alfentanil inhibiting cardiovascular responses to tracheal intubation are 21.343 and 25.043 μg/kg, respectively.

Individualized medication of tacrolimus after liver transplantation guided by CYP3A5*1 gene polymorphisms: a prospective controlled study / 器官移植

Objective To evaluate the safety and efficacy based on cytochrome P450(CYP)3A5*1 gene polymorphisms in guiding the individualized medication of tacrolimus (FK506) after liver transplantation. Methods Clinical data of 100 consecutively enrolled recipients who underwent liver transplantation for the first time were analyzed and randomly divided into experimental group and control group, with 50 cases in each group. The donors and recipients in the experimental group received preoperative CYP3A5 gene detection, and determined the FK506 medication regimen according to the CYP3A5*1 genotype. The compliance rate of FK506 target blood concentration, the recovery rate of liver function in the two groups of recipients at 7, 14, 28 d and 3, 6, 9, 12 months postoperatively, as well as the number of FK506 dosage adjustment during the follow-up were observed. The 1-year graft survival rate and the incidence of complications were recorded in both groups of recipients, such as acute rejection, infection, acute kidney injury, gastrointestinal symptoms, de novo hypertension, de novo diabetes, colds and rash, etc. Results The differences of the compliance rate of FK506 target blood concentration between the two groups of recipients at 7, 14 d after operation were statistically significant (both P < 0.05). There was no statistically significant difference between the two groups in the compliance rate of FK506 target blood concentration at 28 d and 3, 6, 9, 12 months and the recovery rate of liver function at the 7 observation time points after operation (all P > 0.05). The difference between the two groups of recipients in number of FK506 dose adjustment during follow-up was statistically significant (P=0.021). There were no statistically significant differences in 1-year graft survival rate and incidence of complications between the two groups of recipients after operation and during follow-up (all P > 0.05). Conclusions It is safe to guide individualized medication of FK506 after liver transplantation according to CYP3A5*1 gene polymorphism. It can increase the compliance rate of FK506 target blood concentration of recipients in the early postoperative stage, and can effectively reduce the number of dose adjustment duringfollow-up.

Safety application of organs from infectious donors / 器官移植

Objective To explore the safety application of organs from infectious donors. Methods Clinical data of 67 donors and recipients undergoing orthotopic liver transplantation were retrospectively analyzed. According to the occurrence of infections and infection sites in donors, all recipients were divided into the bloodstream infection group (n=16, donors with non-drug resistant bacterial infections), non-bloodstream infection group (n=20, donors with other site infections) and non-infection group (n=31). Perioperative clinical parameters including preoperative model for end-stage liver disease (MELD) score, operative time, anhepatic phase, intraoperative blood loss and intraoperative blood transfusion were statistically compared among three groups. The recovery of liver function and coagulation function in the recipients was observed at postoperative 1, 3, 7, 14 and 21 d. The incidence rate of complications and mortality rate in the recipients were recorded within 1 month after liver transplantation. The recovery of postoperative infection-related parameters including white blood cell (WBC), neutrophil pet (NE%) and procalcitonin (PCT) level in the recipients was observed. The application rate and application time of restricted antibiotics were recorded. Results Perioperative clinical parameters in the recipients did not significantly differ among three groups (all P > 0.05). At each time point after liver transplantation, the liver function, coagulation function, incidence rate of complications and mortality rate in the recipients did not significantly differ among three groups (all P > 0.05). The NE% of recipients at postoperative 3 and 7 d in the bloodstream infection group was significantly higher than those in non-bloodstream infection and non-infection groups (all P < 0.05). The PCT levels of recipients at postoperative 3, 7 and 14 d in the bloodstream infection group were significantly higher than those in the non-bloodstream infection and non-infection groups (all P < 0.05). The application rate and application time of restricted antibiotics in the recipients with bloodstream infections were significantly higher or longer than their counterparts in the non-bloodstream infection and non-infection groups (all P < 0.05). Conclusions It is safe to apply liver grafts from donors with bloodstream infection of non-drug resistant bacteria or other site infections when antibiotics are applied as early as possible.

The value of MELD-Na score in predicting complication severity grades after orthotopic liver transplantation for severe hepatitis / 中华肝胆外科杂志

Objective To study the value of preoperative MELD-Na score (Model for End-Stage Liver Disease-Sodium) in predicting complication severity grades after liver transplantation (LT) for severe hepatitis.Methods Patients who underwent LT for severe hepatitis between August 1,2004,and September 1,2014 were retrospectively studied.The Accordion severity grading system was used to classify the complication severity grades after LT.The grades were classified as grade 1 (mild),grade 2 (moderate),grade 3-5 (severe),and grade 6 (death).The area under the curve (AUC) was calculated by plotting the receiver operating characteristic curve (ROC) to evaluate the predictive accuracy of the MELD-Na score for the severe and mortality grades after LT.The correlation between the MELD-Na score with the complication severity grade after LT was studied by the Spearman correlation and by multivariate analysis.Results The incidences of postoperative complications for the 159 patients in this study were:grade 2 in 43 patients (27.0％,MELD-Na score 27.3 ±7.4),grade 3 in 41 patients (25.8％,MELD-Na score 32.7 ± 12.4),grade 4 in 31 patients (19.5％,MELD-Na score 34.3 ± 12.1),grade 5 in 9 patients (5.7％,MELD-Na score 30.7 ± 12.3),grade 6 in 35 patients (22％,MELD-Na score 37.1 ± 10.4).There was no grade 1 patient.The AUC of the MELD-Na score for the severe and death groups were 0.631 (P ＜ 0.05;95 ％ CI,0.533 ～ 0.728) and 0.670 (P ＜ 0.05;95 ％ CI,0.574 ～ 0.766) respectively.The MELD-Na score was significantly correlated with the Accordion severity grade (rho 0.297,P ＜ 0.01) on Spearman correlation analysis.Multivariate analysis showed that a MELD-Na score ≥25 was a risk factor of postoperative severe grade complication (P ＜ 0.05,OR =4.35),a MELD-Na score ≥35 was a risk factor of postoperative mortality (P ＜0.01,HR =4.72).Conclusion The MELD-Na score was significantly correlated with the Accordion severity grade,which efficaciously predicted the complication severity grades after liver transplantation.

Continuous renal replacement therapy for patients with renal failure after liver transplantation / 中华肝胆外科杂志

Objective To study the therapeutic effect of continuous renal replacement therapy (CRRT) in renal failure after liver transplantation.Methods Renal function in 82 patients who underwent CRRT in the perioperative period of liver transplantation were retrospectively analyzed.Results There were significant differences in ALT,TB,BUN and Cr before and after the treatment (P ＜ 0.05).The differences were significant in glutamic-pyruvic transaminase (ALT),creatinine phosphate kinase (CPK) and C reactive protein (CPR) before and after the treatment (P ＜0.05).There were significant improvements in K+,Na+,Cl-,HCO3-and CVP before and after the treatment (P ＜ 0.05),while the differences were not significant in other biochemical parameters (P ＞ 0.05).This research also looked at the effect of timing of CRRT on renal function recovery.Based on the RIFLE classification of AKI,the ratio of renal function recovery in RIFLE-Ⅰ was significantly higher than RIFLE-F (P ＜ 0.05).Conclusion CRRT treatment significantly improved the prognosis of patients with acute renal failure after liver transplantation.

The reason, diagnosis and treatment of postoperative early cardiac arrhythmia in 500 patients who received orthotopic liver transplantation / 中华肝胆外科杂志

ObjectiveTo summarize and investigate the incidence,reason,diagnosis and treatment of postoperative early cardiac arrhythmia after orthotopic liver transplantation(OLT).Method A retrospective study was made for the incidence,dignosis and treatment of cardiac arrhythmia (two weeks after OLT) following OLT from June 2004 to January 2012 in the Beijing You-An Hospital.ResultsIn 500 patients who received OLT,Cardiac arrhythmia developed in 82 patients (16.4％).Among these cardiac arrhythmia,35(7.0 ％) were sick sinus syndrome (including severe sinus bradycardia ),18 (3.6 ％ ) were paroxysmal supraventricular tachycardia,21(4.2 ％) were atrial fibrillation,8(1.6 ％,including 2 patients with torsades de pointes) were ventricular tachycardia and 4 (0.8 ％ )were cardiac arrest.Mortality rate after OLT relate to cardiac arrhythmia was 0.4％ (2 patients).Cardiac arrhythmia was mainly correlated with four factors:(1)whether patient had heart disease before OLT or not(x2 =15.82,P＜0.01),(2)Prolonged QT interval in patients with end-stage liver disease before OLT(x2 =11.00,P＜0.01).ConclusionsCardiac arrhythmia was common complication after OLT,and it can lead to death of recipients.Careful evaluation to recipients before OLT,controlling fluid load after OLT,keeping the balance of the electrolyte,acidity and alkalescence,giving intensive monitor to patients with heart disease before OLT and prolonged QT interval are the key factor to reduce incidence and mortality of cardiac arrhythmia.Application of medication and cardiac pacemaker can prevent cardiovascular accident after OLT.
