Objective:To correlate serum levels of neuron specific enolase (NSE) and inflammatory factors with recovery of neurological function in patients with severe traumatic brain injury.Methods:Ninety-six patients with severe traumatic brain injury who received treatment from January 2018 to January 2020 in Taizhou Hospital were included in this study. These patients were divided into a mild-to-moderate group ( n = 51) and a severe group ( n = 45). Additional 60 healthy controls who concurrently received health examination were included in the healthy control group. Serum NSE level was detected by enzyme-linked immunosorbent assay, serum C-reactive protein (CRP) level by immunoturbidimetry, serum procalcitonin (PCT) level by chemiluminescent assay, and serum interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) levels by enzyme-linked immunosorbent assay. All patients were followed up for 3 months. Recovery of neurological function was evaluated by modified Rankin Scale. Results:Serum NSE level was (50.42 ± 13.25) μg/L and (36.79 ± 10.28) μg/L in the severe and mild-to-moderate groups, respectively, which was significantly higher than that in the healthy control group [(6.13 ± 1.78) μg/L, t = 25.641, 22.688, both P < 0.05). Serum NSE level in the severe group was significantly higher than that in the mild-to- moderate group ( t = 5.576, P < 0.05). Serum CRP, PCT, IL-6 and TNF-α levels were (78.95 ± 15.46) mg/L, (3.46 ± 0.75) μg/L, (432.15 ± 78.29) μg/L and (36.57 ± 8.98) μg/L] respectively in the severe group, (34.65 ± 7.48) mg/L, (1.68 ± 0.51) μg/L, (285.41 ± 36.75) μg/L and (17.54 ± 5.26) μg/L] respectively in the mild-to-moderate group and (3.25 ± 0.86) mg/L, (0.08 ± 0.02) μg/L, (73.52 ± 13.89) μg/L and (1.64 ± 0.50) μg/L, respectively in the healthy control group. Serum CRP, PCT, IL-6 and TNF-α levels in the severe and mild-to-moderate groups were significantly higher than those in the healthy control group ( t = 37.890, 34.922, 34.870, 30.099, 32.284, 24.315, 40.980, 23.312, all P < 0.05). Serum levels of these indicators in the severe group were significantly higher than those in the mild-to-moderate group ( t = 17.493, 13.414, 11.500, 12.451, all P < 0.05). In the severe group, neurological function recovered well in 34 patients and poorly in 17 patients. Serum NSE level in patients with poor neurological function recovery was significantly higher than that in patients with good recovery [(68.93 ± 14.25) μg/L vs. (34.61 ± 12.36) μg/L, t = 8.457, P < 0.05). Serum CRP [(113.24 ± 27.39) mg/L], PCT [(4.57 ± 0.87) μg/L], IL-6 [(598.90 ± 43.52) μg/L] and TNF-α [(58.78 ± 12.13) μg/L] levels in patients with poor recovery were significantly higher than those in patients with good recovery [(32.19 ± 6.90) mg/L, (2.23 ± 0.65) μg/L, (261.39 ± 26.56) μg/L and (14.53 ± 4.26) μg/L, t = 11.956, 9.788, 29.280 and 14.537, all P < 0.05). Serum NSE, CRP, PCT, IL-6 and TNF-α were positively correlated with poor prognosis ( r = 0.849, 0.743, 0.795, 0.683, 0.701, all P < 0.05). Conclusion:In patients with severe traumatic brain injury, serum NSE, CRP, PCT, IL-6 and TNF-α levels increase, which are positively correlated with poor prognosis.

OBJECTIVETo explore the relationship between electrocardiographic (ECG) and genetic mutations of patients with hypertrophic cardiomyopathy (HCM), and early ECG changes in HCM patients.

METHODSClinical, 12-lead ECG and echocardiographic examination as well as genetic examinations were made in a three-generation Chinses HCM pedigree with 8 family members (4 males). The clinical characterization and ECG parameters were analyzed and their relationship with genotypes in the family was explored.

RESULTSFour missense mutations (MYH7-H1717Q, MYLK2-K324E, KCNQ1-R190W, TMEM70-I147T) were detected in this pedigree. The proband carried all 4 mutations and 5 members carried 2 mutations. Corrected QTc interval of KCNQ1-H1717Q carriers was significantly prolonged and was consistent with the ECG characterization of long QT syndrome. MYLK2-K324E and KCNQ1-R190W carriers presented with Q wave and(or) depressed ST segment, as well as flatted or reversed T waves in leads from anterolateral and inferior ventricular walls. ECG results showed ST segment depression, flat and inverted T wave in the gene mutation carriers with normal echocardiographic examination results. ECG and echocardiographic results were normal in TMEM70-I147T mutation carrier.

CONCLUSIONSThe combined mutations of the genes associated with cardiac ion channels and HCM are linked with the ECG phenotype changes in this HCM pedigree. The variations in ECG parameters due to the genetic mutation appear earlier than the echocardiography and clinical manifestations. Variation in ECG may become one of the indexes for early diagnostic screening and disease progression of the HCM gene mutation carriers.

OBJECTIVETo study the epidemic situation and dominant strain of influenza in children with acute respiratory infection (ARI) during Flu season from Oct. 2005 to Mar. 2006 in Taiyuan.

METHODSMadin-darby canine kidney (MDCK) cell culture and hemagglutination inhibition (HI) assay were used to isolate and identify type A influenza viruses (H1N1 and H3N2) and B influenza viruses from clinical samples collected from outpatients who visited the Department of Pediatric because of ARI from Oct. 2005 to Mar. 2006. Oct. 2005 and Mar. 2006, we collected 415 blood samples from children and adults to detect the influenza virus antibody titers by HI test to exclude respiratory diseases.

RESULTS7 strains of H1N1 were isolated from 87 clinical specimens, with a positive rate of H1N1 as 8.04%. Out of 415 blood samples being collected, the positive rates and the geometric mean titer of H1N1 antibody Mar. 2006 were significantly higher in 0-3, 3-7 and 7-18 year-olds than Oct.2005.

CONCLUSIONH1N1 epidemic influenza did occur among children in winter and spring of 2005--2006 in Taiyuan city.

Objective:To investigate the diagnostic accuracy of serological indicators and evaluate the diagnostic value of a new established combined serological model on identifying the minimal hepatic encephalopathy (MHE) in patients with compensated cirrhosis.Methods:This prospective multicenter study enrolled 263 compensated cirrhotic patients from 23 hospitals in 15 provinces, autonomous regions and municipalities of China between October 2021 and August 2022. Clinical data and laboratory test results were collected, and the model for end-stage liver disease (MELD) score was calculated. Ammonia level was corrected to the upper limit of normal (AMM-ULN) by the baseline blood ammonia measurements/upper limit of the normal reference value. MHE was diagnosed by combined abnormal number connection test-A and abnormal digit symbol test as suggested by Guidelines on the management of hepatic encephalopathy in cirrhosis. The patients were randomly divided (7∶3) into training set ( n=185) and validation set ( n=78) based on caret package of R language. Logistic regression was used to establish a combined model of MHE diagnosis. The diagnostic performance was evaluated by the area under the curve (AUC) of receiver operating characteristic curve, Hosmer-Lemeshow test and calibration curve. The internal verification was carried out by the Bootstrap method ( n=200). AUC comparisons were achieved using the Delong test. Results:In the training set, prevalence of MHE was 37.8% (70/185). There were statistically significant differences in AMM-ULN, albumin, platelet, alkaline phosphatase, international normalized ratio, MELD score and education between non-MHE group and MHE group (all P<0.05). Multivariate Logistic regression analysis showed that AMM-ULN [odds ratio ( OR)=1.78, 95% confidence interval ( CI) 1.05-3.14, P=0.038] and MELD score ( OR=1.11, 95% CI 1.04-1.20, P=0.002) were independent risk factors for MHE, and the AUC for predicting MHE were 0.663, 0.625, respectively. Compared with the use of blood AMM-ULN and MELD score alone, the AUC of the combined model of AMM-ULN, MELD score and education exhibited better predictive performance in determining the presence of MHE was 0.755, the specificity and sensitivity was 85.2% and 55.7%, respectively. Hosmer-Lemeshow test and calibration curve showed that the model had good calibration ( P=0.733). The AUC for internal validation of the combined model for diagnosing MHE was 0.752. In the validation set, the AUC of the combined model for diagnosing MHE was 0.794, and Hosmer-Lemeshow test showed good calibration ( P=0.841). Conclusion:Use of the combined model including AMM-ULN, MELD score and education could improve the predictive efficiency of MHE among patients with compensated cirrhosis.
