ABSTRACT
Malignant tumors in children are one of the most important diseases that threaten the health and quality of life of children and are the second most common cause of death in children.With the continuous improvement and progress of treatment technology, the long-term survival rate of children with tumor has been significantly improved, but both the disease itself and the treatment can impair the immune function of children, which makes them vulnerable to various infectious diseases and secondary serious complications, and even become a source of infection, endangering the health of others. Vaccination is the most cost-effective measure to prevent infectious diseases. For children with normal immune functions, the benefits of vaccination usually outweigh the disadvantages. However, there is a lack of detailed data on the vaccination situation, efficacy and safety of vaccine use for such immunocompromised tumor survivors, and there are no authoritative and uniform vaccination recommendations. This article reviewed and summarized the literature and consensus of some domestic and foreign scholars on current status of post-treatment vaccination status, efficacy and safety of vaccination for children with tumors after treatment, with the aim of providing a reference for the practice in this field in China.

BackgroundStroke patients commonly experience varying degrees of psychological distress. Previous studies have shown that the psychological distress of stroke patients is closely related to their coping styles and resourcefulness. However， the path of wisdom in coping style and psychological pain of stroke patients is still unclear. ObjectiveTo explore the path of resourcefulness between coping styles and psychological distress in stroke patients， so as to provide insights for interventions targeting psychological distress. MethodsA total of 350 patients who met the diagnostic criteria for stroke according to the Diagnostic Criteria of Cerebrovascular Diseases in China （version 2019） and were admitted to the neurology departments of two tertiary grade-A hospitals in Luzhou City from January to May 2023 were selected as the research subjects. Basic information was collected using a self-designed questionnaire， and Resourcefulness Scale （RS）， Medical Coping Mode Questionnaire （MCMQ） and Distress Thermometer （DT） were used for assessment. Pearson correlation analysis was conducted to examine the correlation between the scores of each scale. Model 4 of the Process 3.4.1 program was employed to analyze the path of resourcefulness between coping styles and psychological distress， and the Bootstrap method was used to test the mediation effects. ResultsThe DT score showed a negative correlation with the confrontation and RS scores （r=-0.581， -0.716， P<0.01）， and a positive correlation with the avoidance and resignation scores （r=0.432， 0.758， P<0.01）. The confrontation score was positively correlated with RS score （r=0.700， P<0.01）， while the avoidance and resignation scores were negatively correlated with RS score （r=-0.460， -0.566， P<0.01）. Resourcefulness might serve as a mediating path between confrontation， avoidance， resignation， and psychological distress， with the effect value of -0.359， 0.203 and 0.183， accounting for 81.78%， 62.65% and 27.07% of the path effect， respectively. ConclusionThe coping styles of stroke patients can directly affect their psychological distress， and can also indirectly influence it through resourcefulness. Resourcefulness may play a mediating role between coping styles and psychological distress. ［Funded by Health Humanities Research Center， Zigong Key Research Base for Philosophy and Social Sciences （number， JKRWY22-27）］

ABSTRACT
Objective:To evaluate the nutritional status of patients with decompensated liver cirrhosis and explore the correlation with malnutrition and the risk factors of depressed mood.Methods:190 cirrhotic patients admitted to the Department of Gastroenterology of the First Hospital of Shanxi Medical University from June to September 2023 were selected according to the inclusion and exclusion criteria. Eligible patients were divided into subgroups based on the presence or absence of malnutrition as determined by subjective global assessment (SGA). The Center for Epidemiological Studies Depression (CES-D) scale was used to assess patients' propensity for depressed mood. Relevant clinical data were also collected and analyzed.Results:A total of 185 patients were included, of which 126 were in the non-malnutrition group and 59 malnutrition group. There were significant between-group differences in terms of CES-D results, age, body mass index, platelets, D-dimer, serum sodium, third lumbar skeletal muscle index, grip strength, triceps skinfold thickness, and upper arm muscle circumference (all P<0.05). Correlation analysis showed that grip strength, triceps skinfold thickness, upper arm muscle circumference, serum sodium, and depressed mood tendency status were correlated with the development of cirrhotic malnutrition ( P<0.05). The diagnostic model for malnutrition in cirrhosis using these five indicators showed the area under the curve of 81.9%. Conclusions:Depression is closely related to the development of malnutrition in patients with liver cirrhosis. Independent risk factors for malnutrition in cirrhosis include serum sodium≤135 mmol/L, grip strength, triceps skinfold thickness, lower-than-normal upper arm circumference , and the tendency of depression , which demonstrate the combined contribution to the diagnosis of malnutrition in cirrhosis.
ABSTRACT
Gastrointestinal graft versus host disease is one of the most severe complications after hematopoietic stem cell transplantation, which can occur in patients of any age groups. Its clinical manifestations include nausea, vomit, abdominal pain, diarrhea and the like. Severe gastrointestinal graft versus host disease could directly influence the patients' clinical prognosis and therapeutic efficacy of transplantation. Here we had a review of the research progress on nutritional support and diet management strategies for gastrointestinal graft versus host disease. It is of great clinical significance to form a step-wise nutritional support model to reduce the risk of malnutrition in patients with gastrointestinal graft versus host disease, which would contribute to improving patients' general condition, relieving digestive tract symptoms, and reducing the risk of complications.

ABSTRACT
Objective To explore the learning curve of endoscopic mesothyroid excision via gasless axillary approach.Methods Clinical data of 44 patients who underwent endoscopic mesothyroid excision via gasless axillary approach between May 2020 and December 2022 by the same surgical team were retrospectively analyzed.Taking operation time as index,the learning curve of the operation was studied with the cumulative sum method(CUSUM).The cut-off value of the learning curve was regarded as the dividing line of different stages.The general data,operation time,intraoperative blood loss,hospital stay,number of lymph node dissection,and postoperative complications were compared between the different phases of the learning curve.Results The operations were successfully completed in all the 44 patients without conversion to open surgery.The cumulative sum fitting curve reached the top at the 21st case,which was used as the boundary to divide the learning curve into learning improvement stage and mature stable period.There was no statistically significant difference between the two stages in general data(P>0.05).The operation time in the learning improvement stage was significantly longer than in the mature stable period[(124.5±9.9)min vs.(82.0±8.8)min,t =15.166,P =0.000].The incidence of postoperative sternocleidomastoid muscle swelling and stiffness in patients in the learning improvement stage was higher than that in the mature stable period,but the difference was not statistically significant[6 cases(28.6%)vs.1 case(4.3%),χ2 =3.174,P =0.075].There was no significant difference between the two groups in terms of intraoperative bleeding,hospital stay,number of lymph node dissection,and other postoperative complications(all P>0.05).Conclusion To proficiently master the endoscopic mesothyroid excision via the gasless axillary approach,21 cases need to be completed.
ABSTRACT
Background Occupational stress is an important factor affecting the health of working population, wellness is a topic that has received much attention in recent years, and sleep quality and wellness have a certain impact on occupational stress. Objective To understand the current situation of occupational stress among locomotive engineers in in the Yangtze River Delta, explore the influence of well-being and sleep quality on occupational stress, and provide a theoretical basis for occupational stress intervention among locomotive engineers. Methods Sampling was conducted from October to December 2022 using stratified random sampling. The Chinese version of the Brief Occupational Tension Questionnaire based on the Job Demand-Control Model (JDC model), the World Health Organization 5-item Well-Being Index (WHO-5), and the Pittsburgh Sleep Quality Index (PSQI) scale were used to investigate the occupational stress, well-being, and sleep quality of locomotive engineers. Logistic regression was used to analyze the effects of sleep quality and well-being on occupational stress, and additive and multiplicative interaction models were applied to evaluate the interactive effects of well-being and sleep quality on occupational stress. Results A total of 8243 questionnaires were collected from five locomotive companies, and after excluding unqualified questionnaires, a total of 7976 questionnaires were included in the analysis. The number of locomotive engineers in the Yangtze River Delta reporting positive occupational stress was 4633 (58.09%), the number of low-level well-being was 4949 (62.05%), and the number of poor sleep quality was 4129 (51.77%). The distribution of occupational stress varied by age, length of service, region, technical level, nature of vehicle, education, per capita monthly family income, marital status, smoking, drinking, number of exercise sessions per week, quality of sleep, work shifts, and length of commute (P<0.01). The results of logistic regression showed that a lower level of occupational stress was associated with >11000 yuan per capita monthly household income (OR=0.795, 95%CI: 0.656, 0.964), high level of well-being (OR=0.477, 95%CI: 0.430, 0.528), and good sleep quality (OR=0.588, 95%CI: 0.531, 0.651); a higher level of occupational stress was associated with night shifts: 1 or fewer night shifts (OR=1.707, 95%CI: 1.312, 2.221), 2 to 3 night shifts (OR=2.649, 95%CI: 2.111, 3.325), and 4 or more night shifts (OR=2.804, 95%CI: 2.202, 3.571); a higher level of occupational stress was associated with 60 min or more commuting time (OR=1.353, 95%CI: 1.111, 1.646). Regarding interaction between poor sleep quality and low well-being on occupational stress, the relative excess risk ratio (RERI), attributable risk index (API), and synergy index (SI) were 1.451 (1.059, 1.844), 0.417 (0.327, 0.507), and 2.407 (1.787, 3.241), respectively, and the result of the multiplicative interaction was an OR of 1.546 (95%CI: 1.262, 1.893). Conclusion The prevalence of occupational stress among locomotive engineers in the Yangtze River Delta region is generally at a medium level compared with other industries. Good sleep quality reduces the risk of occupational stress to a greater extent than high well-being, and poor sleep quality and low well-being can interact and further increase the risk of occupational stress.

ABSTRACT
Objective To evaluate the risk of cardiac adverse events in patients with malignant tumors after chemotherapy by using a combination of acoustic cardiography and blood indices. Methods A total of 171 patients with malignant tumor who received chemotherapy were included. They were divided into cardiac adverse event group and non-cardiac adverse event group in accordance with whether cardiac adverse events occurred after chemotherapy. The general data, blood indices before chemotherapy, and acoustic cardiography-related indices in the early stage (1-3 cycles) of chemotherapy of the two groups were analyzed. The possible influencing factors were determined by binary logistic regression analysis, and the nomogram was drawn. The receiver operating characteristic (ROC) curve was used to evaluate the prediction ability of the nomogram. Results Cardiac adverse events occurred in 44 of 171 patients with malignant tumors after chemotherapy, and the incidence of cardiac adverse events was 25.73%. Binary logistic regression results showed that age, red blood cell distribution width (RDW) before chemotherapy, activated partial thromboplastin time (APTT), and electromechanical activation time (EMAT) at the early stage of chemotherapy were independent predictors of cardiac adverse events in chemotherapy patients. The area under the ROC curve of the nomogram was 0.768 (95%CI: 0.693-0.843, P<0.001). Conclusion A nomogram based on age, pre-chemotherapy RDW, APTT, and EMAT at the early stage of chemotherapy is useful for early assessment of the risk of cardiac adverse events in chemotherapy patients.
ABSTRACT
ObjectiveTo investigate the influencing factors for chronic pancreatitis （CP） complicated by pancreatogenic portal hypertension （PPH）， and to establish a predictive model. MethodsA retrospective analysis was performed for the clinical data of 99 patients with CP complicated by PPH who were hospitalized in The First Affiliated Hospital of Kunming Medical University， Chuxiong Yi Autonomous Prefecture People’s Hospital， Wenshan People’s Hospital， and Puer People’s Hospital from January 2017 to December 2022， and these patients were enrolled as PPH group. The incidence density sampling method was used to select 198 CP patients from databases as control group. The independent-samples t test was used for comparison of normally distributed continuous data between two groups， and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups； the chi-square test or the Fisher’s exact test was used for comparison of categorical data between two groups. The Least Absolute Shrinkage and Selection Operator （LASSO） regression model was used to identify the potential predictive factors for CP complicated by PPH， and the predictive factors obtained were included in the multivariate Logistic regression analysis to obtain independent risk factors， which were used to establish a nomogram prediction model. The receiver operating characteristic （ROC） curve， the calibration curve， and the Hosmer-Lemeshow goodness-of-fit test were used to perform internal validation of the model， and the clinical decision curve was used to assess the clinical practicability of the model. ResultsThere were significant differences between the two groups in sex， history of recurrent acute pancreatitis attacks， acute exacerbation of CP， bile duct stones， peripancreatic fluid accumulation， pseudocysts， pulmonary infection， elevated C-reactive protein （CRP）， elevated procalcitonin， fibrinogen （FIB）， neutrophil-lymphocyte ratio （NLR）， gamma-glutamyl transpeptidase， total bilirubin， direct bilirubin， low-density lipoprotein （LDL）， serum amylase， D-dimer， and serum albumin （all P<0.05）. The predictive variables obtained by the LASSO regression analysis included sex， recurrent acute pancreatitis attacks， bile duct stones， peripancreatic fluid accumulation， pulmonary infection， pseudocysts， CRP， NLR， FIB， and LDL. The multivariate Logistic regression analysis showed that sex （odds ratio ［OR］=2.716， P<0.05）， recurrent acute pancreatitis attacks （OR=2.138， P<0.05）， peripancreatic fluid accumulation （OR=2.297， P<0.05）， pseudocysts （OR=2.805， P<0.05）， and FIB （OR=1.313， P<0.05） were independent risk factors for CP complicated by PPH. The above factors were fitted into the model， and the Bootstrap internal validation showed that the nomogram model had an area under the ROC curve of 0.787 （95% confidence interval： 0.730 — 0.844）， and the calibration curve was close to the reference curve. The Hosmer-Lemeshow goodness-of-fit test showed that the model had a good degree of fitting （χ2=7.469， P=0.487）. The clinical decision curve analysis showed that the prediction model had good clinical practicability. ConclusionMale sex， recurrent acute pancreatitis attacks， peripancreatic fluid accumulation， pseudocysts， and FIB are independent risk factors for CP complicated by PPH， and the nomogram model established has good discriminatory ability， calibration， and clinical practicability.
ABSTRACT
Objective To explore the therapeutic effect of mesorectal excision in gasless transaxillary endoscopic thyroidectomy.Methods Clinical data of 75 patients who underwent gasless unilateral transaxillary endoscopic thyroidectomy from May 2020 to November 2022 were retrospectively analyzed.A total of 40 cases were treated with mesorectal excision(observation group),and 35 cases were treated with thyroid resection followed with central lymph node resection(control group).The operation time,intraoperative blood loss,postoperative hospital stay,number of lymph nodes dissected,and postoperative complications were compared between the two groups.Results All the patients successfully completed the operation.As compared with the control group,the observation group had shorter operation time[(91.8±19.7)min vs.(110.4±19.3)min,t =-4.133,P =0.000]and more lymph nodes dissected[(6.5±2.5)vs.(4.6±2.0),t = 3.610,P = 0.001].There were no statistically significant differences between the two groups in the amount of intraoperative bleeding,recurrent laryngeal nerve injury,and the postoperative hospital stay.There was no hypoparathyroidism,postoperative bleeding,or wound infection in both groups.Conclusion Mesorectal excision is safe and feasible in endoscopic thyroidectomy via axillary approach,with more thorough lymph node dissection in the central region and better protection of recurrent laryngeal nerve.
ABSTRACT
Objective:To investigate the correlation between serum sclerostin and sarcopenia-related indicators in chronic kidney disease (CKD) patients, and to find biomarkers and potential therapeutic targets that can take into account both osteoporosis and sarcopenia.Methods:It was a single-centre cross-sectional study. The clinical data of CKD stage 5 patients undergoing maintenance hemodialysis regularly and CKD stage 1-5 non-dialysis inpatients in the Hemodialysis Centre of Guangzhou Red Cross Hospital from March 2021 to March 2023 were collected retrospectively. The enzyme-linked immunosorbent assay was used to detect the level of serum sclerostin. The anthropometric data such as height, weight, upper arm circumference, upper arm muscle circumference, skinfold thickness, pinch strength and handgrip strength were measured. Body composition analyzer was used to measure the body composition. The patients were divided into CKD stage 1-3 group, CKD stage 4-5 group, and stage 5 hemodialysis group. One-way ANOVA, Kruskal-Wallis H test, and chi-square test were used to compare the differences of demographics and clinical characteristics in different stages of CKD. Spearman correlation analysis and multiple linear stepwise regression analysis were utilized to analyze the correlation between serum sclerostin and sarcopenia-related indicators in CKD patients. Results:The study included 104 patients with CKD stage 5 hemodialysis and 104 patients with CKD stage 1-5 non-dialysis patients, with age of (61.8±13.7) years old and 114 males (54.8%). There were 89 patients (42.8%) with diabetic nephropathy and 67 patients (32.2%) with sarcopenia. As renal injury progressed, serum sclerostin levels were 0.4 (0.3, 0.9) ng/L, 0.5 (0.3, 1.1) ng/L, and 1.1 (0.6, 2.3) ng/L in patients with CKD stage 1-3, stage 4-5, and stage 5 undergoing hemodialysis ( χ2=8.934, P<0.001), and the prevalence of sarcopenia was 16.4% (10/61), 34.9% (15/43), and 40.4% (42/104) ( χ2=10.312, P=0.006), respectively. Spearman correlation analysis showed that serum sclerostin was negatively correlated with estimated glomerular filtration rate ( r=-0.314, P<0.001), pinch strength ( r=-0.229, P=0.007), skinfold thickness ( r=-0.254, P<0.001), appendicular skeletal muscle index ( r=-0.169, P=0.010), body cell mass ( r=-0.174, P=0.020), and phase angle ( r=-0.264, P<0.001), and positively correlated with serum phosphorus ( r=0.227, P=0.002) and intact parathyroid hormone ( r=0.297, P<0.001). Multiple linear stepwise regression analysis showed that lg[appendicular skeletal muscle index] was negatively correlated with male ( β=0.330, t=5.675, P<0.001) and serum sclerostin ( β=-0.125, t=-2.143, P=0.033), and positively correlated with body mass index ( β=0.474, t=8.090, P<0.001). Conclusion:Serum sclerostin can be used as a good index and a potential therapeutic target for sarcopenia in CKD patients.

ABSTRACT
ObjectiveTo investigate the expression of essential meiotic endonuclease 1 （EME1） in liver cancer tissue and its effect on the biological behavior of hepatoma cells. MethodsThe TCGA database was used to identify the differentially expressed genes between liver cancer tissue and paracancerous tissue. Immunohistochemistry and Western Blot were used to measure the expression abundance of EME1 in liver cancer tissue. A lentivirus was constructed by short hairpin RNA， and BEL-7404 cells were transfected with the lentivirus to interfere with the expression of the EME1 gene； the cells were divided into silencing group （shEME1 group） and control group （shCtrl group）. Quantitative real-time PCR and Western Blot were used to measure the mRNA and protein expression levels of EME1； Celigo Image Cytometer and MTT assay were used to measure cell proliferation rate； flow cytometry was used to observe cell cycle； Caspase 3/7 activity was used to measure cell apoptosis. The independent-samples t-test was used for comparison between two groups. ResultsTCGA results showed that the mRNA expression level of EME1 in liver cancer tissue was 18.9 times that in paracancerous tissue （t=5.00， P<0.001）， and the protein expression level of EME1 in liver cancer tissue was 7.0 times （based on immunohistochemistry： 8.4±2.6 vs 1.2±0.4， t=7.55， P<0.001） or 2.5 times （based on Western Blot： 249.0%±35.5% vs 100.0%±77.8%， t=3.02， P<0.05） that in paracancerous tissue. After lentivirus infection， compared with the shCtrl group， the shEME1 group had an mRNA expression level of EME1 reduced by 29.9% （29.9%±0.9% vs 100.0%±3.6%， t=32.82， P<0.001）， a protein expression level of EME1 reduced by 35.7% （35.7%±14.9% vs 100.0%±28.9%， t=3.42， P<0.05）， and a level of cell counting reduced by 45.1% （4 053±167 vs 8 988±477， t=16.91， P<0.001）， as well as a level of cell activity reduced to 66.9% （0.518±0.046 vs 0.774±0.022， t=8.74， P<0.001） and a level of colony forming ability reduced to 29.0% （75±6 vs 260±9， t=28.92， P<0.001）. Compared with the shCtrl group， the shEME1 group had a significant increase in the proportion of cells in G1 phase （49.9% vs 44.0%， t=8.96， P<0.001） and significant reductions in the proportion of cells in G2/M phase （15.9% vs 17.9%， t=9.13， P<0.001） and S phase （34.2% vs 38.1%， t=6.91， P<0.001）， while Caspase 3/7 activity was enhanced by 1.5 times （145.8%±5.9% vs 100.0%±2.3%， t=12.50， P<0.001）. ConclusionEME1 is highly expressed in liver cancer tissue， and silencing the EME1 gene can inhibit the proliferation of hepatoma cells and promote cell apoptosis.
ABSTRACT
ObjectiveTo explore the risk factors and survival analysis of chemotherapy compliance in ≥65 years old patients with non-small cell lung cancer. MethodsFrom December 2018 to August 2020， 110 patients with non-small cell lung cancer ≥65 years old in our hospital were selected for study. According to their chemotherapy compliance， the patients were divided into untreated （25 cases）， partial chemotherapy （30 cases） and full chemotherapy （55 cases）. Multivariate Cox regression was used to analyze the independent risk factors affecting the compliance of chemotherapy among the three groups， and constructed a column chart prediction model and evaluated the diagnostic effectiveness of the model using receiver operating characteristic （ROC） curves， calibration curves， and clinical decision curves. The patients were followed up until August 2023. Kaplan-Meyer survival curve and Log-rank test were used to compare the differences in survival time between the groups. ResultsThere were significant differences among the three groups in gender， long-term smoking history， education level， Charlson complication index， toxic and side effects of chemotherapy drugs and dosage， pathological type， operation mode， place of residence， payment mode， chemotherapy stage， white blood cell count and neutrophils （P<0.05）. Multivariate Cox analysis showed that patients' education level， pathological TNM stage， toxic and side effects of chemotherapy drugs and dosage， operation mode， residence， payment mode and chemotherapy stage were independent risk factors affecting chemotherapy compliance of patients with non-small cell lung cancer （all P<0.05）. There were significant differences in the survival rates between the non-chemotherapy group and the full chemotherapy group， and between the partial chemotherapy group and the full chemotherapy group （P<0.05）， but there was no significant difference between the non-chemotherapy group and the partial chemotherapy group （P>0.05）. And based on this， a prediction model was constructed， and the ROC curve was drawn to show that the AUC of the model was 0.758 （95%CI： 0.743‒0.855）， the sensitivity was 0.788， and the specificity was 0.853， indicating that the model had high discrimination， the calibration curve indicated that the prediction model had good accuracy， the clinical decision curve indicated that the predictive model had strong clinical practicality. ConclusionNSCLC tends to occur in the elderly. We should focus on the patients with low educational level， late pathological TNM stage， severe toxicity and side effects， high dose of chemotherapy drugs， having undergone open chest surgery， living in rural areas， without medical insurance， and in the period of chemotherapy consolidation and refractory relapse， so as to improve their compliance with chemotherapy.
ABSTRACT
AIM: To explore the neuro-ophthalmological characteristics of acute macular neuroretinopathy(AMN)after SARS-CoV-2 infection.METHODS: A total of 8 patients(14 eyes), including 6 females and 2 males, who were diagnosed with AMN in the neuro-ophthalmology department of Xi'an No.1 Hospital(The First Affiliated Hospital of Northwest University)from December 27, 2022 to February 1, 2023 were included in the study. All patients had a history of SARS-CoV-2 infection before the disease, and the results of best corrected visual acuity(BCVA), non-contact indirect intraocular pressure measurement, fundus color photography, near infrared(IR), spectral-domain optical coherence tomography(SD-OCT), OCT angiography(OCTA), fundus fluorescein angiography(FFA), indocyanine green angiography(ICGA), visual field, visual evoked potential(VEP), and electroretinogram(ERG)were collected. Furthermore, the neuro-opthalmology characteristics of the included patients were analyzed and summarized.RESULTS: The included 8 patients aged from 20 to 43, with an average age of(30±6.63)years old. The patients had a history of SARS-CoV-2 infection 3 to 11(mean 5±3.51)d before the disease, and 6 out of 8 patients developed visual symptoms within 5 d of infection with SARS-CoV-2, with manifestated with decreased vision or visual scotoma. The visual acuity varied from 0.08 to 1.0, with visual field defect characterized by central, paracentral or peripheral scotoma. VEP showed prolongation latency of P100 or P2, and ERG revealed impaired function of retinal photoreceptor cell. In the early stage of the disease, the size and shape of early visual acuity, visual field, and extraretinal lesions in patients with AMN associated with SARS-CoV-2 infection may not match, and the lower the visual acuity, the later the VEP peaks.CONCLUSION: The neuro-ophthalmic features of SARS-CoV-2 infection-associated AMN require the attention of clinicians. In addition to multi-mode fundus imaging, clinicians should use a variety of methods to comprehensively evaluate visual function and prognosis of patients.
ABSTRACT
Purpose/Significance To provide reference for the information technology laboratory management in universities and col-leges of traditional Chinese medicine(TCM).Method/Process The paper focuses on the main problems faced by information technology laboratory management in universities and colleges of TCM,and proposes ideas of informatization path selection based on practices in Hu-bei University of Chinese Medicine.It constructs informatization management system from the following aspects:network foundation of in-formation technology laboratory,terminal protection cloud service,internet of things technology application,laboratory opening,experi-mental teaching resource sharing,etc.Result/Conclusion The informatization management system significantly improves the utilization rate of the laboratory,greatly reduces the personnel cost and time cost.
ABSTRACT
Objective To describe and analyze the current situation of the four same type of departments in an hospital in order to provide a reference for the construction of"the most cost-effective medical care".Methods The CN-DRG were used to automatically group and compare the medical capacity and inpatient service efficiency of the hospital department groups,and in the refined analysis,one DRG disease group of in situ cancer and non-malignant disease loss uterine surgery and single species uterine fibroid was included,and the Kruskal-Wallis H test was used to further compare the differences in length of stay and various costs.Results It included a total of 22630 patients,whose weights varied from a maximum of 3948.62 in diagnostic group 1 to a minimum of 133.55 in diagnostic group 11.The cost consumption indexes ranged from a minimum of 0.89 in diagnostic group 5 to a maximum of 1.04 in diagnostic group 2,while the time consumption indexes ranged from a minimum of 0.48 in diagnostic group 11 to a maximum of 0.81 in diagnostic group 5.When comparing the diagnostic groups,there were statistically significant differences(P＜0.05)in hospitalization days,total cost,diagnostic cost,therapeutic cost,and cost of supplies.Specifically,when comparing the diagnostic and treatment groups within departments,the differences in hospitalization days and all costs were statistically significant(P＜0.05)in departments 1 and 2,the differences in diagnostic cost,therapeutic cost,and cost of supplies were statistically significant(P＜0.05)in department 3.Conclusion There exists a notable disparity in the extent to which each diagnostic and treatment group contributes to the hospital's service capacity and cost variability.Consequently,it is necessary to reasonably evaluate the length of hospital stay and medical cost of patients to achieve the highest cost-effective medical treatment.
