Standardized clinical behavioral assessment remains the cornerstone for diagnosing disorders of consciousness (DoC). Nevertheless, mounting evidences underscore the substantial risk of misdiagnosis associated with exclusive reliance on behavioral evaluations. In contemporary neuroscience research, advanced neuroimaging and electrophysiological methodologies have emerged as powerful tools; these techniques not only enable in-depth characterization of the dynamic alterations in brain structure and function among DoC patients but also furnish critical insights for clinical decision-making, including accurate diagnosis, prognosis, and tailored therapeutic strategies. This review synthesizes the recent advance in applying neuroimaging and electrophysiological approaches in DoC diagnosis and prognosis evaluation, and discusses its technical advantages, clinical application scenarios and limitations, in order to provide new ideas and methods for DoC diagnosis and prognosis evaluation.

Objective:To investigate the relationship between Triglyceride Glucose-WHR index and retinal arteriosclerosis.Methods:Retrospective longitudinal cohort research method. Using data from the Tongren Health Care Study of Beijing Tongren Hospital from March 2014 to June 2020. The TyG-WHR index was calculated, the restricted cubic spine regression model was used to explore the dose-response relationship between TyG-WHR index and the risk of retinal arteriosclerosis. Cox proportional regression model was implemented to estimate the impact on the risk of retinal arteriosclerosis associated with the different TyG-WHR groups. Receiver operating characteristic were used to explore the value of triglyceride glucose-WHR index for the risk of retinal arteriosclerosis.Results:A total of 8 215 subjects were included, including 3 334 (40.58%) males, 4 881 (59.42%) females;7 689 cases had normal fundus, 296 cases had newly developed retinal arteriosclerosis, and 230 cases had retinal arteriosclerosis. The median age is 45 years old, and the average age is (47.63±13.89) years old. The cumulative incidence rate of new retinal arteriosclerosis was 3.71%(296/7 985), and the cumulative incidence rate of women (3.31%,158/4 767) was lower than that of men (4.29%, 138/3 218) ( χ2=5.105, P<0.001); The cumulative incidence rate of new retinal arteriosclerosis increased with age ( χ2=365.133, P<0.001); The TyG-WHR index was divided into four groups according to the interquartile range, and the Q2- Q4 group had an increased risk of developing new retinal arteriosclerosis compared to Q1 ( χ2=132.887, P<0.001).In the restricted cubic spine regression model, the results showed a non-linear dose-response relationship ( χ2=54.27, P<0.001) between baseline TyG-WHR index and the new-onset of retinal arteriosclerosis. By the multivariate Cox Regression models, three models were constructed in this study. TyG-WHR index was positively correlated with the risk of retinal arteriosclerosis: the HR (95% CI) of model 1-3 was 1.534,1.517 and 1.502.The AUC curve analysis verified that the prediction AUC of the TyG-WHR index for new-onset retinal arteriosclerosis was 0.755, the best prediction value was 7.343, the sensitivity was 90.2%, and the specificity was 75.60%. Conclusion:TyG-WHR index may be an independent risk factor for new-onset retinal arteriosclerosis.

Objective:To explore the application of an automatic slide-dropping instrument in bone marrow chromosomal karyotyping.Methods:The effects of manual and automatic dropping methods under different environmental humidity were retrospectively analyzed, and the repeatability of the automatic dropping method was analyzed.Results:No statistical difference was found between the results of automatic and manual dropping methods under the optimum ambient humidity and high humidity ( P>0.05). At low humidity, there was a statistical difference between the two methods ( P<0.05). With regard to the repeatability, the coefficient of variations of the automatic dropping method for the number of split phases, the rate of good dispersion and the rate of overlap were all lower than those of the manual dropping method. A statistical difference was also found in the number of split phases ( P<0.05) but not in the discrete excellent rate and overlapping rate between the two methods ( P>0.05). Conclusion:Better effect can be obtained by the automatic dropping instrument. It is suggested to gradually replace manual work with machine.

Objective:To investigate the prevalence and risk factors of hypertensive retinopathy (HRP) in a non-diabetic population over 30 years old during routine health examinations.Methods:This was a cross-sectional study of a non-diabetic population over 30 years of age. The study was conducted during routine health examinations at the Tongren Hospital, Beijing, from January to December 2020. Fundus photographs were taken, and data including medical history, height, weight, and blood pressure were collected. Routine laboratory examinations were performed. The study population was divided into hypertension, transient hypertension, and non-hypertension groups. The prevalence of HRP was compared among the three groups. OR and 95% CI of HRP risk factors was estimated by binary logistic regression, adjusted for age and gender. Results:The prevalence of HRP was 4.3% in the non-diabetic population over 30 years old. Adjusted for age, gender, and systolic blood pressure, the prevalence of HRP in hypertension and transient hypertension groups, was both higher than in the non-hypertension group [ OR(95% CI) of 3.11(2.25-4.30) and 1.72(1.21-2.45), respectively]. The proportion of grade 1-2 HRP was higher (76.2%). There was no significant difference in the prevalence of grade 3 HRP among the three groups. Adjusted for age and gender, systolic blood pressure and creatinine clearance rate were independent risk factors for HRP in the hypertension group [ OR(95% CI): 1.22(1.01-1.48) and 1.66(1.12-2.46)] and transient hypertension group [ OR(95% CI): 1.48(1.10-2.06) and 1.95(1.03-3.46)]. SBP and DBP were independent risk factors for HRP in the non-hypertension group [ OR(95% CI): 1.68(1.07-2.63) and 1.61(1.06-2.44)]. Conclusions:There was a high prevalence of HRP among the non-diabetic population over the age of 30 and there was still relatively high risk of grade 3 HRP among the normotensive population.

Objective To investigate the prevalence and risk factors of diabetic retinopathy (DR) in a Beijing population during routine medical examinations. Methods This was a cross-sectional study during a routine health examination at the Tongren Hospital of Beijing,from March 2014 to February 2015. Fundus photography was conducted by experienced ophthalmologists.Medical history,height,weight,waist and hip circumference,and blood pressure were recorded.Routine laboratory examinations were performed. Logistic regression models were used to estimate the odds ratio (OR) and 95% confidence interval (CI) of diabetic retinopathy for each risk factor,adjusted for age and gender. Results The prevalence of DR was 7.0% among diabetic individuals.The multivariate analysis showed that disease durations[OR(95% CI),2.1 (1.564-2.752),P<0.001],fasting plasma glucose[1.2(1.093-1.273),P<0.001],body mass index[1.8(1.010-3.100),P=0.046],and triglyceride[0.794(0.638-0.987),P=0.038]were independently associated with DR. The prevalence of diabetes mellitus (DM) and DR significantly increased in populations aged>30 years. Conclusion Fundus photography (nonmydriatic) should be recommended as a routine screening method for people 30 years and elder to effectively prevent occurrence of visual impairment and blindness.

Objective To investigate the application value of perioperative enhanced recovery after surgery (ERAS) combined with laparoscopic common bile duct exploration (LCBDE) in the treatment of choledocholithiasis.Methods The clinical data of 84 patients with choledocholithiasis who were admitted to the Yijishan Hospital from January 2011 to December 2013 were prospectively analyzed.A single-blind,randomized,controlled study was performed in the 75 patients who were allocated into the control group and the enhanced recovery after surgery group (ERAS group) based on a random number table.All the patients underwent LCBDE,the patients in the control group received conventional perioperative management and the patients in the ERAS group received perioperative management according to enhanced recovery rehabilitation program.All the patients were followed up by outpatient interview till postoperative month 6.The clinical features,liver function and residual stones in the patients were observed.The operation time,postoperative complications,postoperative intestinal function recovery,duration of hospital stay and hospital expenses in the two groups were compared.Measurement data with normal distribution were presented as x ± s.Comparison between groups were evaluated with an independant sample t test.Count data were analyzed using the chi-square test.Results All the 75 eligible patients undergoing successful operation were randomly divided into the control group (35 patients) and the ERAS group (40 patients).The operation time and volume of intraoperative blood loss in the control group and the ERAS group were (185 ±46)minutes and (124 ±28)mL,(178 ±37) minutes and (114 ±32)mL,respectively,with no significant difference (t =0.729,1.431,P ＞ 0.05).There were 12,14 and 10 patients in the control group and 5,6 and 4 patients in the ERAS group with postoperative incision pain,vomit and infection,showing a significant difference (x2=5.054,5.966,4.241,P ＜ 0.05).The level of white blood cell,alanine aminotrausferase and direct bilirubin in the control group and in the ERAS group were (11.4 ± 3.5) × 109/L,(128 ± 33)U/L,(38 ±14) μmol/L and (10.6 ± 3.0) × 109/L,(135 ± 35) U/L,(44 ± 16) μmol/L at postoperative day 1,compared with (7.8 ±2.9) × 109/L,(48 ± 14) U/L,(21 ± 8) μmol/L and (6.9 ±2.1) × 109/L,(43 ± 13) U/L,(20 ±7) μmol/L in the 2 groups at postoperative day 4,respectively,showing no significant difference between the 2 groups (t =1.018,-0.872,-1.767,1.553,1.836,1.044,P ＞ 0.05).The postoperative first flatus day,time of food intake,time of postoperative infusion and duration of hospital stay were (42 ± 13)hour,(45 ±14) hours,(6.8 ±2.3)days and (11.3 ±4.5)days in the control group,and (35± 11)hours,(19 ±7)hours,(4.2 ± 1.8) days and (9.6 ± 2.4) days in the ERAS group,with a significant difference between the 2 groups (t =2.741,10.524,5.485,2.077,P ＜ 0.05).The total hospital expenses was (18 729 ± 3 127) yuan in the control group,which was significantly greater than (16 981 ±2 756) yuan in the ERAS group (t =2.574,P ＜ 0.05).The liver function of all the patients was recovered at the postoperative month 1.Four patients with residual stones in the 2 groups were detected by T-tube cholangiography,and were cured by removal of gallstones by choledochoscopy.There were no complications of the abdominal pain,jaundice and fever in all the patients till the end of follow-up.Conclusion ERAS combined with LCBDE for the treatment of choledocholithiasis is safe and feasible,with the advantages of low morbidity,quick recovery,short duration of hospital stay and less hospital expenses.
