Depression and insomnia are intimately related. Depressed patients usually manifest sleep discontinuity and early awakening, reduced or no slow wave sleep (SWS) and shortened latency of rapid eye movement (REM) sleep. These sleep abnormalities are very similar to those caused by over activated hypothalamic-pituitary-adrenal (HPA) axis with stress. Therefore, the animal models developed by post-traumatic stress disorder or chronic unpredictable mild stress could be used to evaluate drugs which have effects of both anti-depression and improvement of sleep quality, and to provide a more reliable platform for further studis on the mechanisms of depression and accompanied insomnia. This review mainly focuses on the typical features of sleep disturbance of depression, possible pathophysiological mechanisms, establishment of animal stress models and analysis of their abnormal sleep characteristics.

Objective To evaluate the post-puncture complications in children,and to evaluate the difference in the occurrence rate of headache and backache between patients who had 1 hour of supine recumbency and those who had 4 hours of supine recumbency,to provide evidence for the standardized lumbar puncture (LP) procedure of children.Methods Inpatients who were older than 3 and had diagnostic LP in the course of their treatment between Nov.2012 and Apr.2013 were enrolled.The LP was performed by the same investigator under the standardized institutional guideline for LP and the information of number of LP attempts,duration of LP and cerebrospinal fluid (CSF) drainage volume were recorded.After the procedure,all the children were randomly assigned into 2 groups:the test group had supine recumbency for 1 hour after LP,and the control group had it for 4 hours.For the first 5 days following LP,reports of headache and backache were recorded by another physician who didn't participate in this study.The difference in the occurrence rate of headache and backache between test group and control group was assessed by the chi-square test or Fisher's probabilities in 2 × 2 table.And a Logistic regression analysis was performed to assess the risk factors for the occurrence of the headache and backache.Results The overall frequency of headache was 4.6％ (4/87 cases).The frequency of headache was not significantly different between the test group (2.4％) and control group (6.7％) (P =0.617).And the overall frequency of backache was 19.5 ％ (17/87 cases),and it was not significantly different between the 2 groups (test group:21.4％,control group:17.8 ％,P =0.668).In a Logistic regression analysis,age (P =0.011,OR:6.884,95％ CI:1.398-33.906) and the previous history of lumbar puncture (P =0.018,0R:0.126,95 ％ CI:0.026-0.618) were significant risk factors for the occurrence of backache.The risk of backache in children with more than 2 times of LP was decreased.And the risk was higher in the children older than 6 years than those younger than 6 years.Conclusions Headache and backache were the most frequent post-puncture complications in children.There was no difference between short duration (1 hour) of supine recumbency and long duration (4 hours) in preventing the occurrence of headache and backache after LP.

Objective To analyze the multi-slice computed tomography (MSCT) enhanced findings in the patients with primary small intestinal stromal tumor(SIST),and to probe the relationship between the imaging findings and the pathologic risk in order to improve the diagnostic accuracy.Methods Thirty patients with primary SIST confirmed by surgical pathology were enrolled in this study.Characterization and compassion of the clinical manifestations and MSCT enhanced findings were carried out between the pathologic low-and high-risk groups.Furthermore,the relationship was analyzed between the enhanced findings and the pathologic risk.Results Among all 30 patients with primary SIST,the lesion was located at duodenum in 5 patients (16.7％),at jejunum in 16 (53.3％),and at ileum in 9 (30％).14 patients were classified in the low risk group with the lesion with the average length of (3.8±0.9) cm,and other 16 in the high-risk group with lesion with the average length of (7.0 ± 1.4) cm.There were no statistical differences between the low-and high-risk groups in CT value in plain and venous phase,and in added value in arterial,venous and delayed phases.However,the significantly differences were observed in CT value in arterial and delayed phases between two groups (P＜0.05).Conclusion MSCT may effectively evaluate the pathologic risk of primary SIST.There are significant differences of the enhanced findings between the low and high-risk groups,which can provide important apreoperative classification for the therapy.

AIM:To explore the survivorship and the mechanism of the intravenous administration of bone marrow stromal stem cells(BMSCs) for treating permanent focal cerebral ischemia in rats.METHODS:After purified,proliferated,and marked with BrdU,the BMSCs were injected intravenously into rats 1 d after focal cerebral ischemia.Modified neurological severity score(mNSS) was evaluated before and following 1,7,14 and 28 d after middle cerebral artery occlusion(MCAO).Rats were executed at 1,7,14 and 28 d after MCAO.Brain sections were stained with hematoxylin and eosin(HE) for determining the infarct volume.Slides were stained by the terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick-end labeling(TUNEL) and immunostaining for cleaved caspase-3 method for apoptosis detection and mechanism exploration in situ.RESULTS:mNSS in BMSCs-transplanted group at 14th day and 28th day of MCAO was significantly lower than that in control group(P

Abstract: Objective　To establish a risk prediction model for nosocomial infection in preterm very low birth weight infants, and conduct internal validation. Methods　A total of 206 cases of very low birth weight premature infants hospitalized in the Department of Neonatology of Union Hospital Affiliated to Tongji Medical College from January 2018 to June 2020 were included in this study, factors that may affect the nosocomial infection of children were collected, and the infants were divided into two groups according to whether there is nosocomial infection. The influencing factors were compared between the two groups, and multivariate Logistic regression analysis was performed after screening variables with LASSO regression. According to the results of multi factor analysis, the nomogram model was constructed and verified internally. Results　A total of 29 of 206 children had nosocomial infection (14.08%), and 33 pathogenic bacteria were detected, including 23 Gram-negative bacteria, 9 Gram-positive bacteria and 1 fungus. The results of multivariate logistic regression analysis based on LASSO regression showed that the risk factors for nosocomial infection of VLBW premature infants were 28-31+6 weeks of gestation, amniotic fluid pollution, mechanical ventilation, indwelling gastric tube, unreasonable use of antibiotics, and hospitalization time ≥ 7 days. The protective factors were Apgar score ≥ 7 points at 1 min and breast feeding accounting for 50% or more (P<0.05). The Area Under Curve (AUC) of ROC curve of nomogram model was 0.946 [95%CI(0.923, 1.000)]. The calibration curve showed that the probability of hospital infection predicted by the model was basically consistent with the actual probability. The decision curve showed that when the probability threshold of nomogram model to predict the risk of nosocomial infection of very low birth weight premature infants was 0-0.85, the net rate of return was greater than 0. Conclusion　Preterm infants with extremely low birth weight are at high risk of nosocomial infection, mainly affected by factors such as gestational weeks, hospitalization time, amniotic fluid pollution, etc. The nomogram model constructed by the above factors has high accuracy and discrimination for predicting nosocomial infection in such children.

BACKGROUND: The minimal latency and conduction velocity of F-wave have been widely used for the detection of varied neurological disorders,whereas the significance and the diagnostic value for the other parameters of F wave are seldom reported. How sensitive are these parameters in the earlier evaluation of diabetic peripheral neuropathy (DPN) ?OBJECTIVE: To investigate the evaluating value of F-wave parameters for the earlier DPN, providing references for earlier clinical rehabilitative intervention.DESIGN: Case-control study with type 2 diabetic patients and health people as subjects.SETTING: The wards and outpatients in the Departments of Neurology and Endocrinology, Renmin Hospital of Wuhan University.PARTICIPANTS: Between January 1999 and December 2000, there were totally 106 patients with type 2 diabetic mellitus(DM) at the wards and outpatients in the department of neurology and endocrinology in Renmin Hospital of Wuhan University, including 64 males and 42 females, with the average age of (55 ± 13) years and the average DM course of (10.2 ± 4. 8)years. Meanwhile, 75 healthy volunteers were enrolled in the control group,including 45 males and 30 females, with the mean age of(54 ± 12) years.Two groups were matched in age and leg length( P ＞ 0. 05).INTERVENTIONS: Using Nicolet Viking-Ⅳ, F wave and M-wave parameters of tibial nerve stimulation were analyzed.MAIN OUTCOME MEASURES: The minimum latency (Fmin), duration (Fdur), amplitude(Famp) and area(Farca) of F wave; and the amplitude (Mamp)and aera(Marea) of M-wave.neuropathy( n = 30), there were 8 cases(the abnormal rate being 27% ) with increased Fdur, 4(13% ) with prolonged Fmin and 2(7% ) with increased F/Mamp and F/Marea increased significantly in the patients with DPN( n = 76).mality rate of Fdur was significantly higher (96% vs 21%, P ＜0.01), the abnormality rate of Fmin was significantly lower(51% vs 76%, P ＜ 0.05 ) and there were no significant difference of other parameters( P ＞ 0.05) in the patients with mild DPN subgroup ( n = 47).diagnostic parameter for earlier DPN, and therefore detect the sub-clinical DPN, and the proximal may be earlier involved than the distal.

The effects of over-expression of ANXA10 gene on proliferation and apoptosis of hepato-cellular carcinoma cell line HepG2 were elucidated. The human ANXA10 gene was subcloned into the lentiviral vector, PGC-FU, to generate the lentiviral expression vector, PGC-FU-ANXA10. The corrected ANXA10 was confirmed by endoenzyme digestion, and sequencing. Recombinant lentiviruses were produced by 293T cells following the co-transfection of PGC-FU-ANXA10 with the packaging plasmids pHelper1.0 and pHelper2.0. The resulting recombinant lentiviruses carrying ANXA10 were then used to infect human embryonic kidney epithelial cells, and lentiviral particles were produced. The ANXA10 expression in 293T cells was detected by using fluorescent microscope and Western blotting. HepG2 cells were infected, and divided into PGC-Fu-ANXA10 group, PGC-Fu group and HepG2 cell group. The changes of ANXA10 mRNA and protein expression were detected by using RT-PCR and Western blotting respectively. Flow cytometry and MTT assay were performed to examine the changes in cell apoptosis and proliferation respectively. The recombinant PGC-FU-ANXA10 vector was successfully constructed, the ANXA10 protein was detected by using Western blotting, and virus titer was 2×10(8) TU/mL. The recombinant lentiviruses were effectively infected into HepG2 cells in vitro and the infection efficiency was 70%. At 72 h after infection, the ANXA10 mRNA and protein expression levels in PGC-Fu-ANXA10 group were significantly higher than in PGC-Fu group and HepG2 cell group (P<0.05); the in vitro growth inhibition rate of HepG2 cells in PGC-Fu-ANXA10 group was 24.65%, significantly higher than that in PGC-Fu group and HepG2 cell group (P<0.05), but there was no significant difference between PGC-Fu group and HepG2 cell group; the apoptosis rate in PGC-Fu-ANXA10 group, PGC-Fu group and HepG2 cell group was (51.92±1.41)%, (19.00±1.12)% and (3.59±0.89)% respectively. The apoptosis rate in PGC-Fu-ANXA10 group was significantly higher than in PGC-Fu group and HepG2 cell group (P<0.05). The recombinant lentiviruses PGC-FU-ANXA10 were constructed successfully and infected into HepG2 cells. The overexpression of ANXA10 gene can significantly inhibit proliferation and promote apoptosis of HepG2 cells in vitro.
