Objective To explore the inhibitory effect of melatonin(MT) on expression of glial fibrillary acidic protein in infant rats with brain injury induced by lipopolysaccharide(LPS).Methods One hundred and sixty Spragne-Dawley rats(1 month) were randomly divided into 4 groups:9 g/L saline group(NS group),LPS group,MT protective A group(MT plus LPS,MT was given 15 minutes earlier),and MT protective B group(MT plus LPS,MT was given immediately).Forty rats in each group,then every group was subdivided into 2 subgroups according to observe time point at 24 h and 48 h with 20 rats,respectively.Half of them in all subgroups were not injected Evans blue(EB).Rats were sacrificed at 2 time points to take brain tissue samples,respectively.EB content of brain tissue was meteraged by the formamide methods.Immunohistochemistry technology and computer assisted image analysis system methods were applied to observe the expression of the positive apoptosis cell of brain tissue.Results Both EB content and the expression of GFAP showed significant difference between LPS group and NS group(Pa0.05).Conclusions LPS can induce the expression of GFAP in infectious brain injury of rats induced by LPS,and MT can inhibit the expression of GFAP;MT may play a role in dealing with infectious brain injury.

Objective To investigate the influence of Ethyl pyruvate(EP) on the level of high mobility group box 1 (HMGB1) in brain injury of infant rats induced by lipopolysaccharide (LPS) and its significance.Methods Two hundred and forty normal healthy 1-month-old Spragne-Dawley (SD) rats were randomly divided into 3 groups:9 g/L sodium chloride (NS) group(n=80),LPS group (n=80),and EP group (n=80).LPS (1 mg/kg) was injected via internal carotid.In EP group,after injecting LPS,each rat was immediately administrated 4 mL EP(40 mg/kg) intraperitoneally; in control group,4 mL Ringer's solution was given instead of EP.Rats were decapitated at 6,12,24,48 and 72 h following drug injection.The evan's blue (EB) content of brain tissues was meteraged by the formamide methods.Immunohistochemistry technology was used to detect the expression of HMGB1,neuron specific enolase(NSE) and glial fibrillary acidic protein(GFAP) protein,and reverse transcribe polymerase chain reaction technology was applied to study the expression level of HMGB1 mRNA in brain tissue.Meanwhile,the pathological changes of brain tissues were observed under the light microscope.Results Six hours after LPS was given,brain EB content,the levels of NSE,GFAP protein started to rise,reaching the peak at 24 h,and still higher than those in control group at 48 h and 72 h.The expression pattern of HMGB1 protein and mRNA in brain tissue was consistent with the severity of brain injury,increased at 6 h after LPS was given and reached the peak at 24 h,still higher than those in control group at 48 h and 72 h.Positive correlation was found among HMGB1 protein,HMGB1 mRNA and EB content,NSE protein,GFAP protein,respectively.In EP group,the levels of HMGB1 protein and mRNA,the levels of brain EB content,NSE,GFAP protein were found,positive correlation was still gotten between HMGB1 protein,EB content and NSE,GFAP protein,HMGB1 mRNA in LPS group and EP group.Conclusion EP has neuroprotective effect on brain injury induced by LPS,which may be relevant to decreasing of the expression of HMGB1 and suppressing inflammation action.

RhoA, a small GTPase, is involved in a wide array of cellular functions in the central nervous system, such as cell motility, cytoskeleton rearrangement, transcriptional regulation, phagocytosis and cell growth. It is not known how spinal cord injury (SCI) affects the expression of RhoA in different nerve cells. In the present study, we investigated the changes of RhoA expression in remote areas of the injury at the 3rd, 7th and 30th day after SCI, which was established by T10 contusion method. Moreover, we examine its expression profile in neurons, astrocytes and microglia. RhoA was found to be weakly expressed in these nerve cells in normal spinal cord. Western blotting showed that, after SCI, the total RhoA expression was up-regulated, and the RhoA expression was increased and peaked at the 7th day. Double immunostaining revealed specific and temporal expression patterns of RhoA in different nerve cells. The expression of RhoA in neurons started to increase at day 3, peaked at day 7 and then decreased slightly at day 30. Expression of RhoA in astrocytes increased moderately after SCI and peaked at day 7. There was no obvious change in RhoA expression in microglia after SCI in remote areas. This study demonstrated that, after SCI, RhoA expression exhibited different patterns with different nerve cells of spinal cord. RhoA expression patterns also changed with time after SCI, and among different nerve cells in the injured spinal cord. These findings can help us better understand the roles of RhoA in SCI.

Objective To explore the relationship between X - linked spondyloepiphyseal dysplasia tarda (SEDL) gene escaping X chromosome inactivation( XCI) and SEDL phenotype. Methods RT - PCR was performed on total RNA which was isolated from blood samples of patients, female carriers and controls. Patients and female carriers were selected from the pedigree with SEDL caused by the mutation (IVS2 - 2A→C) of the gene. cDNA was analyzed by polyacrylamide gelelectrophoresis(PAGE). Results PAGE data indicateed that female carriers expressed both normal and mutant SEDL mRNA,meaning the SEDL gene escaping XCI. Family investigation showed carrier females in the SEDL pedigree presented no symptoms. Conclusions The SEDL gene escaping X chromosome in-activation is firstly identified from human body. This may explain that carrier females present no symptoms.

Trans-rectal ultrasound is widely used in the diagnosis of rectal cancer.Elastography technique is based on the endorectal conventional ultrasound and can assess tumor stiffness and further detect the characteristics of tumor.It is helpful to provide more information for the differential diagnosis of rectal cancer,preoperative staging and the chemotherapy efficacy evaluation.The applications of strain elastography in the diagnosis of rectal cancer were reviewed in this article.

Objective To observe the clinical effects of hyaluronidase iontophoresis in the treatment of in- fants with congenital muscular torticollis(CMT).Methods Fifty infants with congenital muscular torticollis were divided randomly into a treatment group and a control group.Manual stretching was performed with both groups,while hyaluronidase iontophoresis was also administered to those in the treatment group.The range of side-flexion and rota- tion of the neck was examined at the beginning of and after 1 and 2 months of treatment.At the end of the treatment, the overall outcome was assessed according to a scoring system.Results There was no significant difference be- tween the two groups at admission.Compared with the control group,the range of side-flexion and rotation of the neck,and the overall treatment outcome were all significantly better in the treatment group after treatment.Conclu- sion Hyaluronidase iontophoresis can effectively improve function in infants with CMT and alleviate their symptoms.

OBJECTIVE To strengthen the management of earthquake victims with nosocomial infection,in order to prevent and control the multidrug-resistance transmission,and the nosocomial infection outbreak. METHODS All 77 earthquake victims were under real-time monitoring. RESULTS Of 77 cases,53 were infected (69.74%). From 83 samples,83 pathogenic bacteria were isolated. The Gram-positive cocci were 19 (meticillin-resistant Staphylococcus aureus 3,Meticillin-resistant S. epidermidis 7),58 were Gram-negative bacilli (Acinetobacter baumannii 21,multi-drug resistant strains 10,ESBLs positive Escherichia coli 10,Pseudomonas aeruginosa 9) and the fungi were 6 strains,The resistance rates of Gram-positive cocci to penicillin,ampicillin/sulbactam and cefazolin were 89.47%,68.42% and 89.47%; the resistance rates of Gram-negative bacillis to imipenem,cefoperazone/sulbactam,piperacillin/tazobactam,azithromycin,tobramycin,and cefoxitin were 37.93%,60.34%,48.83%,98.28%,98.28% and 70.69%,respectively. CONCLUSIONS Under the situation of higher infection rate and a serious drug resistance in earthquake area,there are no multidrug-resistance transmissionm and the spread of nosocomiol infection outbreak happened in hospital due to strictly enforced prevention meassures and access real-time monitoring and management,
