Neurons and glia in the central nervous system can express the key enzymes for the synthesis of neurosteroids .Once the concentration of neurosteroids is high enough , they will exert paracrine effects .Synthesis of neurosteroids declines with age in brain .So does it under stressful circumstances .Recent research reports indicate that the decrease of neurosteroids is associated with the neuronal dysfunction and degeneration in the brain .This paper reviews recent research on the most studied neurosteroids ( for example , dehydroepiandrosterone , pregnenolone and their sulphate esters, progesterone and allopregnanolone ) in affecting neuronal survival , neurite outgrowth and neurogenesis , and the potential roles of these neurosteroids in the treatment of neurodegenerative disease as well .

Objective To study the feasibility of the measurement of the thickness of rabbit knee joint cartilage by comparing the optical coherence tomography (OCT)and the undecalcified frozen section method on respectively measure the thickness of New Zeal-and white rabbit’s knee cartilage.Methods 50 standardized cultivation,adult and male New Zealand white rabbits (100 knees) were selected in this study.The measurement point was at the knee weight-bearing area of the medial femoral condyle with a 2 milli-meter diameter trephine,and the cartilage thickness data at the same center point and ±0.5 mm from the center were obtained.OCT and freeze-sectioning method were adopted at each site,respectively.The difference between OCT and histological method was com-pared and Bland-Altman plot was constructed.Results The thickness results of the center,+0.5 mm,-0.5 mm points were (296.5± 1.6)μm,(302.6± 3.5)μm,(287.9±5.6)μm by OCT,(278.4±1.9)μm,(290.3±5.9)μm,(280.3±4.6)μm by freeze-sectio-ning method,respectively.In Bland-Altman diagram,mean difference and 95% confidence interval were 18.1 1 (1 6.65,1 9.56)μm, 12.4 (5.5,1 9.2)μm,7.4 (2.8,12.0)μm.Intra-class correlation coefficients(ICC)for resemblance between the 2 techniques were 0.93(95%CI:0.89-0.95,P <0.000 1),0.84(95%CI:0.77-0.89,P <0.000 1),0.91(95%CI:0.87 -0.94,P <0.000 1),respec-tively.Conclusion As compared with the measurement of undecalcified frozen section,OCT for the rabbits’knee joint cartilage thickness measurement is feasible with the advantages of noninvasiveness,good repeatability.OCT can provide data reference in ani-mal experiments of cartilage tissue engineering for articular cartilage defect repair.

BACKGROUND: Splenic autotransplantation has been presently involved in the treatment of traumatic splenic rupture. Yhere have been retoorts regarding nuclein examination and immunologic test used to monitor splenic autotransplant. But little is known about ultrasonic visualization for follow up of splenic autotransplant. OBJECTIVE: To investigate the value of ultrasonography in monitoring splenic autotransplant survival and growth. DESIGN, TIME AND SETTING: The present retrospective case analysis Was performed at the Department of Ultrasonography. Shenzhen Second People's Hospital between January 2000 and December 2004.PARTICIPANTS:Eighteen patients undergoing splenectomy and suffering from traumatic splenic rupture,13 males and 5 females. aged 20-42 years, were included for this study. METHODS: Non-injured autologous splenic tissue was prepared into thin sections with an area of(2-4)cm×(1-3)cm and a thickness of≤0.5 cm. And transplanted into the greater omentum with abundant vessels in patients undergoing splenectomy.A1118 patients received ultrasonography at 3,6,and 12 months after splenic transplantation, and were subjected to spleen imaging with99Tcm-heat damaged red blood cells. MAIN OUTCOME MEASURES: Nuclein examination of splenic autotransplant survival and growth. RESULTS: Splenic autotransplants survived and gradually grew in 14 of 18 patients. Splenic autotransplants exhibited low level echo similar to normal spleen, regular contour, clear boundary, and visible internal blood flow signal. Splenic autotransplants were not found growing in 4 patients with accessory spleen. CONCLUSION: Ultrasonography can precisely monitor splenic autotransplant survival and growth.

Objective To assess the diagnostic performance of real-time contrast-enhanced ultra-sound Sonovuein diagnosing minute rabbit liver VX 2 tumors with diameter ≤10.0 mm.Methods Thir-ty New Zealand white rabbits inoculated with VX 2 tumor ( left, right lobe of each ) were examined by two-di-mensional ultrasound and CEUS .The contrast enhanced mode of small rabbit liver VX 2 tumors in different phase was observed and tumor in the rabbit's liver was pathologically verified .The diagnostic performances of two-dimensional US and CEUS in detecting the rabbit VX 2 tumors were analyzed and compared .Results Thirty-nine tumors were pathologically verified .The detection rates of small tumors by CEUS and two-di-mensional US were 12.8% and 79.5%, respectively , yielded significantly higher than that of 2-D US.

Objective To probe the value of ultrasound in detection of malignant foci among multiple thyroid nodules. Methods Ultrasonograms of 83 patients with pathologically confirmed thyroid cancer combined with benign nodules were analyzed.Results Among 83 patients of thyroid carcinoma, 89 malignant and 87 benign nodules were detected with ultrasound. Significant differences of two-dimensional ultrasounic signs including low echoes, border fuzzy, micro-calcification and rear echo attenuation were found bteween malignant and benign nodules (P<0.01). There were significant differences in the grade Ⅱ, Ⅲ blood flow between malignant and benign ones (P<0.01). Of 89 malignant nodules, small thyroid carcinoma with diameter ≤1 cm accounted for 52.81% (47/89), and ultrasound diagnostic rate of all cancer nodules was 67.42% (60/89).Conclusion Ultrasounic characteristics including low echoes, border fuzzy, micro-calcification, rear echo attenuation and internal rich blood flow contribute to differentiate the thyroid microcarcinoma from multinodules.In particular, the microcarcinoma should not be ignored.

Objective:To explore the impact of hypophosphatemia on the occurrence and prognosis of critically ill patient.Methods:The clinical data of critically ill patients admitted to the intensive care unit (ICU) of Tianjin First Central Hospital from October 2021 to April 2022 were retrospectively analyzed. Patients were divided into hypophosphatemia group (serum phosphorus level < 0.80 mmol/L) and non-hypophosphatemia group (serum phosphorus level ≥ 0.80 mmol/L) when they were admitted to the ICU. The following variables were also collected, including gender, age, acute physiology and chronic health evaluationⅡ(APACHE Ⅱ), sequential organ failure assessment (SOFA), serum phosphorus level, serum calcium level, serum magnesium level, white blood cell count (WBC), neutrophil count (NEU), lymphocyte count (LYM), neutrophil/lymphocyte ratio (NLR), C-reactive protein (CRP), presence of infection and infection site, length of hospital stay, ICU stay, 28-day mortality, and mechanical ventilation time. Multivariate Logistic regression analysis was used to evaluate the relationship between each variable and the 28-day mortality. The receiver operator characteristic curve (ROC curve) was drawn, and the area under the ROC curve (AUC) and 95% confidence interval (95% CI) were calculated to evaluate the predictive value of serum phosphorus levels for the prognosis of ICU patients. Results:A total of 263 patients were enrolled, including 54 patients with hypophosphatemia and 209 patients without. The SOFA score, LYM level and the infection rate of patients in the hypophosphatemia group were significantly higher than those in the non-hypophosphatemia group [SOFA score: 6.70±3.17 vs. 5.64±3.59, LYM (×10 9/L): 0.99±0.54 vs. 0.77±0.54, infection rate: 77.78% (42/54) vs. 59.33% (124/209), all P < 0.05], the NLR was significantly lower than that of the non-hypophosphatemia group [10.67 (7.08, 18.02) vs. 12.25 (7.25, 21.68), P < 0.05]. The length of hospital stay, ICU stay, and mechanical ventilation duration in the hypophosphatemia group were significantly longer than those in the non-hypophosphatemia group [length of hospital stay (days): 15 (11, 28) vs. 12 (6, 21), length of ICU stay (days): 10.35±7.80 vs 7.15±6.61, mechanical ventilation duration (days): 3 (0, 12) vs. 2 (0, 5), all P < 0.05]. There was no significant difference in the 28-day mortality between the hypophosphatemia group and the non-hypophosphatemia group [9.26% (5/54) vs. 11.00% (23/209), P > 0.05]. Multivariate Logistic regression analysis showed that APACHE Ⅱ score [odds ratio ( OR) = 1.188, 95% CI was 1.110-1.271], CRP ( OR = 1.016, 95% CI was 1.007-1.026), and NLR ( OR = 1.002, 95% CI was 0.996-1.008) were independent risk factors affecting the 28-day mortality of critically ill patients in ICU (all P < 0.05). ROC curve analysis showed that the AUC of serum phosphorus levels for predicting the length of hospital stay of critically ill patients in ICU > 10 days, ICU stay > 5 days, and mechanical ventilation duration > 5 days were 0.701 (95% CI was 0.632-0.770), 0.771 (95% CI was 0.691-0.852), 0.617 (95% CI was 0.541-0.692), respectively, all P < 0.01. Conclusion:Hypophosphatemia has some predictive value for the length of hospital and ICU stay and mechanical ventilation time in critically ill patients, but it cannot predict the 28-day mortality.
