Objectives:To observe the clinical features,related factors,prevention and treauments of complications on early enteral nutrition(EN) in severe head injured patients.Methods:360 patients with severe head injuries were enrolled in this study.GCS score was used to assess the patient's situation.After nasogastric(jejunal) tube was inserted,enteral nutrition was started from 48 hours after injury.The maximal EN volume(mL/d) in the first week after injury,time used for reaching to TEN(d),number of patients that achieved TEN in the first week following injury,blood glucose,serum albumin and ALT were observed.The complications due to enteral nutrition were analyzed. Results:Features of complications with early EN were that the abdominal distension,vomiting and aspiration were found in the first week and diarrhea occurred in the following weeks.A positive correlation between abdominal distension,vomiting and nasogastric tube was noted,while diarrhea had a negative correlation to GCS score and albumin level. Conclusions:The complications related to early enteral nutrition after severe head trauma correlated inversely to the degree of injury and serum albumin level.Utilization of nasojejunal tube could decrease the incidences of abdominal distension and vomiting.

Objective To discuss the clinical value of subglottic secretion drainage on pulmonary infection in severe craniocerebral injuried patients. Methods Eighty severe craniocerebral injuried patients in ICU with the requirement of tracheotomy were randomized into two groups. Forty patients received aspiration of subglottic secretions as the treatment group and the other 40 patients received usual care as control. Samples were taken from pharynx mop, subglottic secretion and lower respiratory tract secretion for bacterial culture at 48 hours, 7th day and 14th day past tracheotomy. Results The incidence of pulmonary infection was 22.5% in treatment group and 45.0% in control. The same rate of predominant flora in subglottic secretion and lower respiratory tract secretion was 63.0% in patients with pulmonary infection. Conclusions Transposition of the pathologic bacteria in the subglottic secretion is one of the important causes of pulmonary infection, subglottic secretion drainage can lower the incidence of pulmonary infection in severe craniocerebral injuried patients.

The treatment group (61 cases) received enteral nutrition support on the 2nd day after operation, and growth hormone was combined for one week. The control group (61 cases) received total parenteral nutrition(TPN) support. The clinical effect and complications were observed between the two groups. Results: The patientss serum pre-albumin , transferrin ,albumin , and nitrogen balance in the treatment group were significantly better than those in the control group (P

An investigation of the current nurse-patient relationship is conducted in Guangzhou city,by analyzing the data it can be concluded that the attitude of nursing service and skills of communication,the degree of nurses' knowledge on their patients' cases have a significant influence on the nurse-patient relationship.Nurses should play a leading role in nurse-patient relationship.There is a lack of mutual consideration and understanding between nurses and patients,which lead to nurse-patient misunderstanding and conflicts.There is a strong desire to discuss the case together intensively between nurses and patients.Furthermore,the lack of effective communication and teamwork between medical staff will also hinder the relief of tension in current physician-patient relationship.

Objective To establish the pharmacodynamic model of sevoflurane with bispectral index (BIS) as the effective index in pediatric patients.Methods Thirteen ASA physical status Ⅰ or Ⅱ pediatric patients,aged 4-9 yr,weighing 12-39 kg,undergoing non-cardiac surgery,were selected in the study.The pediatric patients sequentially inhaled 1％,5 ％ and 1％ sevoflurane via a face mask and each concentration was inhaled for 15 min.BIS value,HR,BP and SpO2 were automatically recorded every 10 s.Based on nonlinear mixed effect modeling,the population pharmacodynamic model of sevoflurane was established using NONMEM software.The effect of age on the pharmacodynamic parameters was evaluated using a stepwise forward addition then backward elimination modeling approach.The standard for model improvement was defined as a decrease in the value of the objective function by more than 3.84.Results Twelve pediatric patients,aged 4.0-8.5 yr,weighing 12.8-38.0 kg,with body height of 92-135 cm,were enrolled in this study and the data which were enrolled comprised 2964 effective concentration-time-BIS points.The model was not improved significantly with any covariates (age,body height,and body weight) introduced (P ＞ 0.05).The estimated parameters of the final pharmacodynamic model of sevoflurane were as follows:ke0 =O.516/min ; EC50 (BIS50) =2.11％ ; γ =2.46 ; E0 =74.6 ; EMAx =11.2.Conclusion The pharmacodynamic model of sevoflurane is successfully established with BIS as the effective index in pediatric patients,and the analysis for each parameter of the model indicates that the sensitivity to sevoflurane is lower,but the blood-brain equilibration time of the drug is shorter and the onset and recovery are faster in children than in adults.

Objective: To investigate the molecular mechanism and identify potential drugs for subthreshold depression (SD), and elucidate the detalied mechanism of Danzhi Xiaoyao powder (DZXY) in SD. Methods: Using RNA-sequencing, we identified differentially expressed genes (DEGs) in leukocytes of SD compared to healthy controls, deciphered their functions and pathways, and identified the hub genes of SD. We also assessed changes in leukocyte transcription factor activity in patients with SD using the TELiS platform. The Connectivity Map database was retrieved to screen candidate drugs for SD. Based on network pharmacology, we elucidated the “multi-component, multi-target, and multi-pathway” mechanism of DZXY in the treatment of SD. Results: We identified 1080 DEGs (padj <0.05 and |log2 (fold change)| ≥ 1 & protein coding) in the leukocytes of patients with SD. These DEGs, including hub genes, were primarily involved in immune and inflammatory response-related processes. Transcription factor activity analysis revealed similarities between the leukocyte transcriptome profile in SD and the conserved transcriptional response to adversities in immune cells. Connectivity Map analysis identified 28 potential drugs for SD treatment, particularly SB-202190 and TWS-119. Constructing the “Direct Compounds-Direct Targets-Pathways” network for DZXY and SD revealed the curative mechanisms of DZXY in SD, primarily including inflammatory response, lipid metabolism, immune response, and other processes. Conclusion These results provide new insights into the characteristics and functional changes of leukocytes in SD, partially illustrate the pathogenesis of SD, and suggest potential drugs for SD. The curative mechanisms of DZXY in SD are also partially elucidated.

The aim of this study was to investigate the expression and immunologic regulation function of interleukin-23 and its related cytokines in chronic idiopathic thrombocytopenic purpura (ITP) patients. Levels of cytokines in peripheral blood mononuclear cells (PBMNC) were detected by reverse-transcription real-time polymerase chain reaction in 30 patients with chronic ITP and 15 healthy volunteers. The quantity of IL-23, IL-12, IL-17 in serum was detected by enzyme-linked immunosorbent assay (ELISA). The results showed that low detectable mRNA levels of IL-23p19, IL-12p35, IL-27 and IL-12p40 were found in all patients and healthy persons. Trace of IL-17 mRNA were expressed in PBMNC of part of patients and normal controls. Levels of IL-12p35, IL-27, IL-17 mRNA between healthy persons and chronic ITP patients were not statistically different. Compared with normal controls, patients showed the lower expression levels of IL-23p19 and IL-12p40 mRNA (p < 0.01). The IL-12 levels of chronic ITP patients were significantly higher than that of normal controls (p < 0.01). The IL-23 and IL-17 levels of chronic ITP patients were same to that of normal controls. It is concluded that the imbalance of T cell subsets in ITP patients mainly associated with IL-12, but not with IL-23 and IL-17.

Objective: To compare the differences and caused of patients' utilization of Traditional Chinese Medicine service under three basic medical insurance systems.Methods: Using self-developed questionnaire,random sample survey was conducted among the basic medical insurance outpatients in five hospitals in Nanjing and Lanzhou.The survey content included the basic information of the patients,the utilization of Traditional Chinese Medicine outpatient clinics,the utilization of Traditional Chinese Medicine service items,and the suggestions for the Traditional Chinese Medicine service.Results:①The utilization rate of the Traditional Chinese Medicine out-patient clinics in new rural cooperative medical system patients was much lower than that in urban basic medical in-surance patients.②The utilization rate of Traditional Chinese Medicine service projects in patients under basic medical insurance for urban employees was higher than those under medical insurance for urban residents and new rural cooperative medical system patients.In all Traditional Chinese Medicine service projects,the utilization rate of cupping project was the highest(48.3％).③ The gap between urban and rural areas made the utilization rate of Traditional Chinese Medicine service projects different among patients participating in basic medical insurances.④ The most expected suggestion of patients was the improvement of the efficacy of Traditional Chinese Medicine(68.5％),followed by the improvement of medical insurance-related reimbursement ratio(65.2％)and the in-crease of reimbursement items(64.3％).Conclusion: The government should increase the financial input in new rural cooperative medical system and improve the basic medical insurance system.Traditional Chinese Medicine medical institutions should improve the quality of services in order to achieve the fairness in the provision of health services.

Objective: To investigate the clinical significance of transcranial Doppler (TCD) in early diagnosis of sepsis-associated encephalopathy(SAE). Methods: Septic patients admitted to the intensive care unit(ICU) were recruited at Xiangya Hospital, Central South University from July 2015 to March 2016. Clinical data and TCD parameters during 24 hours after admission were collected. All patients were screened for delirium using the confusion assessment method for the intensive care unit (CAM-ICU) twice a day. The gold standard of the diagnosis of SAE was positive CAM-ICU evaluation. Patients were divided into SAE group and the non-SAE group. TCD data including systolic velocity (Vs), diastolic velocity (Vd), mean velocity (Vm), pulsatility index (PI) and resistant index (RI) were analyzed to determine the optimal diagnostic cut-off value. Results: A total of 43 patients were enrolled including 12 in SAE group and 31 in non-SAE group. Vm and Vd were lower in SAE group [Vm: (53.50±12.22) cm/s vs. (61.68±9.63) cm/s, P<0.05; Vd: (33.42±10.87) cm/s vs. (43.16±7.84) cm/s, P<0.01] but PI and RI were significant higher in SAE group[PI:(1.16±0.2) vs. (0.90±0.15), P<0.01;RI:(0.65±0.08) vs. (0.56±0.06), P<0.01] than in non-SAE group. The cut-off values of Vs, Vm, Vd, PI and RI for the diagnosis of SAE were 112cm/s, 55.50cm/s, 34.50cm/s, 1.16, 0.65, respectively, with the relevant sensitivities of 19.4%, 83.9%, 93.5%, 58.3%, 58.3% and the specificities of 100.0%, 50.0%, 58.3%, 96.8%, 96.8%, respectively. The diagnostic AUC of Vd, PI and RI were 0.741, 0.808 and 0.808 respectively. Conclusions The parameter changes of TCD suggest that the pathogenesis of SAE is related to cerebral hypoperfusion, TCD is a helpful method for the early diagnosis of SAE.

Objective:This study aimed to explore the structural and functional characteristics of the fecal-associated microbiome(FAM)between the phlegm-dampness constitution(PDC)and balanced consti-tution(BC),and to screen the related specific operational taxonomic unit(OTU)biomarkers.Methods:This was a cross-sectional study.After strictly identifying the constitution of subjects,their clinical index was recorded and counted.Fecal samples were collected for 16S rDNA sequencing.Alpha diversity,beta diversity,and the relative abundance of dominant bacterial taxa were used to describe the FAM structure,and the Wilcoxon rank-sum test,MetagenomeSeq,and linear discriminant analysis effect size(LEfSe)were used to screen specific bacterial taxa.Specific OTUs were screened to construct receiver operating characteristic(ROC)curves.Results:Thirty-two subjects were enrolled,including 22 subjects with BC and 10 subjects with PDC.There were significant differences in cold preference,levels of aspartate transaminase,β2-microglobulin,and creatine kinase MB,and alpha diversity indices(Shannon and Shannoneven)between the two groups.In principal coordinate analysis by abund-jaccard distance measure and partial least squares discriminant analysis,bacterial communities clustered separately between the two groups.Furthermore,based on MetagenomeSeq,LEfSe,and the Wilcoxon rank-sum test,a total of 43,18,and 130 OTUs were differentially distributed between BC group and PDC group,respectively,and OTU200,OTU133,and OTU353 were screened when P＜.01.The area under the ROC curve constructed from the 3 selected OTUs was 0.93.Conclusion:The FAM structure and related functional characteristics of the PDC group differed from those of the BC group.In particular,OTU200,OTU133,and OTU353 can be used as unique markers of PDC to assist clinical diagnosis.
