Objective To observe the early rehabilitation effect of mild hypothermia on patients with herpes simplex viral encephalitis (HSE). Methods A total of 58 patients with HSE were randomized into two groups, a mild hypothermia therapy group (30 cases) and a normothermia control group (28 cases). Their rectal temperatures were controlled to (34±1)℃ and (37.0±0.5)℃ respectively. Serum levels of neuron specific enolase (NSE) were determined through radio-immunoassay (RIA). Soluble intercellular adhesion molecule-1 (sICAM-1) was measured with ELISA before and 1, 3, 5, and 7 d after treatment. The outcome was evaluated using the Glasgow Outcome Scale (GOS) 30 days after treatment. Results Compared with the normothermia control group, the mild hypothermia group's serum levels of NSE and sICAM-1 decreased quickly and significantly during the early stage of treatment and remained better 30 d later. Conclusion Mild hypothermia therapy can dramatically reduce inflamma-tion and facilitate the rehabilitation of damaged neurons, provide protective effects and improve the outcome for pa-tients with SHE.

Objective To explore the value of combined use of laboratory indicators for diagnosis of early renal functional damage. Methods Eighty-six patients with various kidney diseases were enrolled in the Second Affiliated Hospital of Guangzhou Medical University. On admission,the serum Cystatin C(Cys C),creatinine(Cr), Urea,etc were determined. The value of using combined laboratory indicators in the diagnosis of renal functional damage was obtained through the analysis of the receiver operating characteristic curve(ROC curve);multiple variable indicators were grouped to establish multiple logistic regression models to be compared and evaluated. Results In the early and late renal injury groups(group B of 32 cases and group C of 12 cases),the serum levels of Cys C,Cr, and Urea were significantly higher than those in the normal renal function control group(group A of 42 cases),the elevation in level in group C being the most significant〔Cys C(mg/L):3.47±0.75 vs. 1.59±1.29,Cr(μmol/L):669±466 vs. 214±173,Urea(mmol/L):21.22±13.10 vs. 11.04±8.24,P<0.05 or P<0.01〕. The areas under the ROC curve(AUC)made by combinations of Cys C,Cr and Urea for the diagnosis of renal damage were 0.908,0.817 and 0.785. In the four different kinds of combination of the indicators,the AUC were sequentially arranged from large to small area as follows:Cys C+Cr+Urea=Cys C+Cr>Cys C+Urea>Cys C>Cr+Urea(0.920=0.920>0.911>0.908>0.809). In this sequence,the AUC made by Cys C+Cr+Urea and Cys C+Cr were equal,both 0.920, whose sensitivity was 75.0%,specificity 100.0%,positive predictive value 100.0%,negative predictive value 80.0%and diagnostic accuracy rate 87.5%. So,Cys C + Cr combination could be used to substitute Cys C + Cr + Urea, and the former clinical diagnostic effect was the best,much higher than that by using AUC whose curve was made by Cys C alone. Conclusion The value of using only one laboratory indicator for diagnosis of patients with early renal functional damage is not high,while applying Cys C+Cr combination can improve the diagnostic effect greatly,and its sensitivity and specificity are higher.

Objective To investigate the diagnostic value of laboratory evaluation of renal injury in early diagnosis index. Methods Eighty-six patients in in-patient and out-patient of the department of urology were tested in serum C (Cys C), serum creatinine (Cr) and serum UREA nitrogen (UREA). According to the diagnostics (sixth edition), we evaluated their values for diagnosis of renal injury by analyzing the characteristics of the work curve (ROC). Results According to the renal function indexes, 3 groups were divided such as group A (normal renal function control Ccr 80 mL/min) or the Cys C, Cr, and UREA in (0.47 ± 0.24) mg/L, (85 ± 14) μmol/L, and (4.55 ± 1.33) mmol/L, group B (a decrease in renal function reserves, and renal insufficiency 20 mL/min or less Ccr < 80 mL/min) of Cys C, Cr, and UREA in (1.59 ± 1.29) mg/L, (214 ± 173) μmol/L, and (11.04 ± 8.24) mmol/L and group C (renal failure and uremia Ccr < 20 mL/min) of Cys C, Cr, and UREA in (3.47 ± 0.75) mg/L, (669 ± 466) μmol/L, and (21.22 ± 13.10) mmol/L respectively. As reducing in Ccr, Cys C, Scr and UREA concentration increased and correlated with Ccr negatively. According to the mazimum Youden index, the critical values of Cys C, Cr, and UREA were 0.90 (mg/L), 115 (μmol/L) and 7.33 (mmol/L) separately, the sensitivity (%), specificity, positive predictive value (%), negative predictive value (%), diagnostic accuracy (%) and the area of the ROC curve (AUC) were Cys C (77.3%, 97.6%, 97.0%, 81.1%, 77.3%, 0.908), Cr (65.9%, 97.6%, 96.5%, 74.1%, 65.9%, 0.817), and UREA (63.6%, 97.6%, 96.4%, 72.8%, 63.6%, 0.785) respectively. The diagnostic accuracy showed that the Cys C > Cr > UREA. Their correspounding ROC curve (AUC) were in the area of 0.908, and 0.785 and 0817. Cys C had the highest AUC (0.908), and achieved a good diagnosis effect. Conclusion Renal damage laboratory indexes of in the early diagnosis, Cys C has a higher sensitivity and specificity to be worth of clinical promotion.

Objective:To learn about the status of iodine deficiency disorders (IDD) and iodine nutrition of residents in Shanxi Province since the implementation of the standard of "Iodine Content in Edible Salt" (GB 26878-2011), to evaluate the level of prevention and control of IDD, and to provide scientific basis for adjusting prevention and control strategies.Methods:The data of core indicators monitored by Shanxi Province in accordance with the requirements of the national iodized salt and IDD monitoring program for each year from 2012 to 2021 were comprehensively reviewed, and the change trends of the indicators such as coverage rate of iodized salt, consumption rate of qualified iodized salt, children's median urinary iodine and goiter rate, and pregnant women's median urinary iodine were analyzed; the evaluation of IDD elimination in counties (cities and districts, hereinafter referred to as counties) was analyzed.Results:From 2012 to 2021, the coverage rate of iodized salt in Shanxi Province was remained > 95%; from 2012 to 2014 (transition period between new and old standard iodized salt), the consumption rate of qualified iodized salt had an upward trend (χ 2trend = 2 703.32, P < 0.001), with a downward trend from 2015 to 2017 (before and after the reform of the salt industry system, χ 2trend = 122.18, P < 0.001), and with an upward trend from 2018 to 2021 (after the reform of the salt industry system, χ 2trend = 455.11, P < 0.001), from 2018, the consumption rate of qualified iodized salt remained > 90%; from 2015 to 2021, the average content of salt iodine was between 23 - 25 mg/kg, and the coefficient of variation of salt iodine was 15% - 18%. From 2014 to 2021, the median urinary iodine of children in Shanxi Province remained at 200 - 250 μg/L, the median urinary iodine of pregnant women remained at 150 - 200 μg/L, and the goiter rate of children remained below 5%. Every year, iodine nutrition of pregnant women in some counties was insufficient. In 2016, the proportion of counties with insufficient iodine nutrition of pregnant women was high, reached 30.0% (12/40); from 2018 to 2021, the proportion of counties with insufficient iodine nutrition of pregnant women had a downward trend (χ 2trend = 9.37, P = 0.002), which was 11.1% (13/117) in 2021. In 2020, 117 counties in the province reached the IDD elimination standard, with a compliance rate of 100.0%. Conclusions:Since the implementation of the current salt iodine content standard for 10 years, the consumption rate of qualified iodized salt has gradually stabilized and remained at a high level, which can ensure that IDD is in a sustainable state of elimination in Shanxi Province, and the iodine nutrition of school-age children and pregnant women is generally at a suitable level. However, there are a certain number of counties with insufficient iodine nutrition of pregnant women. It is recommended to guide pregnant women to supplement iodine or set the average standard of salt iodine for pregnant women separately.
