Objective: To study the characteristics of suicides treated in the emergency department of a large general hospital in China, so as to provide relevant data for preventing suicide. Methods:Study the records of 183 suicides in the emergency department of XuanWu hospital during Jan 1st to Dec 31 of 2004. Result:Among all suicide cases, young people (aged 20 to 29 years) were the most (81cases, 44.3%); Females (n=147) outnumbered males (n=36, f:m=4.1:1); 170 (92.8%) cases had ingested poisons, among them, 119 used hypnotics or pesticides. The mortality was 3.3% (6/183), that of males (3/36=8.33%) was much higher than that of females (3/147=2.04%); Most of suicides happened during 18 to 24 o'clock(71cases, 38.8%)(P

Objective To investigate clinical first selected method on the differential diagnosis at early stage between amyotrophic lateral sclerosis(ALS) and cervical spondylosis.Methods The clinical features and EMG in 53 patients with ALS,14 patients with cervical spondylotic myelopathy(CSM) and 23 patients with cervical spondylotic radiculopathy(CSR) were analysed.And then the value of ratio of every probability was calculated.According to the value of ratio, the clinical features and EMG were compared in differential dia gnosis.Results A multiprogram that consisted of high multiple clinical features was used in differential diagnosis, true positive rate is 98%, and true negative rate is 86.5%,EMG still couldn't be used in the differential diagnosis.Conclusion The program is the first selected method, which can be used in the differential diagnosis between ALS and CSM/CSR.

This paper summarize the perioperative nursing of 12 newborns with thyroglossal cyst. The preoperative nursing measures focused on prone position,gastric tube feeding,close monitoring of vital signs and tracheal intubation as needed. If the TeSO2 was normal,oxygen therapy was not recommended. After the operation,continuously monitoring vital signs,respiratory care and use of sedatives as needed were carried out. As a result,all of the 12 infants recovered and discharged.

This paper summarizes the nursing experience of 9 very low birth weight infants with catheter-related infections. Among the 132 very low birth weight infants with PICC,9 cases suffered from catheter-related infections. Three cases showed positive results on the germiculture of catheter tip and blood, two cases showed positive result only on the germiculture of blood, and four cases showed negative results on both germiculture of catheter tip and blood. One infant's parent gave up the treatment and eight cases were cured. It is suggested that closely monitoring the signs of infections and taking effective treatment and nursing care as early as possible were the key points of infection control.

Retinoic acid (RA) receptor, is a group of ligand-regulated nuclear transcription factors and widely distributed in various tissue cells. The different subtypes of RA receptor can polymerize into homologous or heterogenous dimmers, and then participate in the physiological and pathological processes of embryonic development, cell proliferation and differentiation, and apoptosis. However, the relationship between the expression of RA receptor and the diseases is different in diverse cells or tissues. Recent researches demonstrated that RA receptor is closely related to the pathogenesis and development of renal diseases. This article aims to review the role of the RA receptor and its signal pathway in the development of renal diseases.

Objective To study the expression of IL 1?,TNF ? and nitric oxide (NO) in the cervical intervertebral disc and their roles in the pathogenesis of cervical spondylotic myelopathy (CSM). Methods Fifteen cervical discs were obtained from patients of CSM undergoing anterior disc surgery. Six cervical discs specimens were obtained in the surgical operation with patients with traumatic cervical injury served as the control. The specimens were analyzed for IL 1?、TNF ? by use of ELISA method, NO was measured by optical density assays. Results The contents of IL 1?,TNF ? and NO in disc of CSM patients increased significantly when compared with the control group. Conclusion The results of the present study indicated that IL 1?,TNF ? and NO may be involved in the pathogenesis of CSM.

Objective　To investigate the effect of breast milk and some other kinds of infant foods on the adhesion of EPEC to Hela cells and intestinal mucosa so as to understand the possible protective mechanism of breast-feeding in the intestine of infants. Methods　The adhesion of EPEC to Hela cells and intestinal mucosa were examined by cell culture, bacterial adherence test, light and electron microscopy in the mediums that contain breast milk, cow's milk and formula milk or contain ecal filtrate of the infants fed by breast milk and formula milk respectively. Results　Adhesive index for EPEC to Hela cells was significantly lower in the medium containing breast milk than in control and so did in the fecal medium containing breast fed infants than artificial feeding infants. Conclusion　Breast milk may inhibit the adhesion of EPEC to infant intestine.

Objective To investigate the effect of all-trans retinoic acid (ATRA) on transforming growth factor β1 (TGF-β1)/Notch signaling pathway in injured podocytes induced by adriamycin (ADR) in vitro.Methods Podocytes cultured in vitro were randomly divided into normal group,model group,ATRA treatment control group,12-hour ATRA intervention group and 24-hour ATRA intervention group.Morphological changes were observed by using light microscope.The expressions of TGF-β1,podocin,Notch 1,Jagged 1 mRNA were evaluated through real-time polymerase chain reaction (RT-PCR) and the corresponding proteins were detected by using Western blot.Results (1) No obvious changes between normal group and ATRA treatment control group were revealed as the plump podocytes and distinct outline were found in light microscope,while podocytes in model group showed disordered arrangement,fuzzy boundary,atrophy,hypertrophy and increased cellular debris.Of note,the podocytes in 12-hour ATRA intervention group and 24-hour ATRA intervention group almost returned to normal.(2) In contrast with those in model group,the amounts of TGF-β1,Notchl,Jaggedl mRNA levels decreased in 12-hour ATRA intervention group (1.34 ±0.43 vs.4.16 ±0.31,1.67 ±0.2 vs.4.21 ±0.92,2.08 ±0.27 vs.5.14 ±0.63,q =23.83,11.45,19.67,all P ＜0.05) and 24-hour ATRA intervention group (1.22 ± 0.16 vs.4.16 ± 0.31,1.73 ± 0.53 vs.4.21 ± 0.92,2.08 ± 0.29 vs.5.14 ± 0.63,q =24.85,11.18,19.67,all P ＜ 0.05),and the differences were significant;similar trend was detected in the protein levels (1.04 ± 0.03 vs.4.31 ± 0.10,1.06 ± 0.04 vs.4.47 ± 0.24,1.07 ± 0.04 vs.4.20 ± 0.16,1.06 ±0.03 vs.4.31 ±0.10,1.07 ±0.03 vs.4.47 ±0.24,1.09 ±0.03 vs.4.20 ±0.16,q =163.50,69.61,90.36,162.50,69.40,89.78,all P ＜ 0.05),and the differences were significant;whereas the level of podocin mRNA (1.13 ±0.05 vs.0.40 ± 0.06,1.16 ± 0.03 vs.0.40 ± 0.06,q =36.50,38.00,all P ＜ 0.05) and protein (1.01 ± 0.01 vs.0.44 ±0.01,1.02 ±0.01 vs.0.44 ±0.01,q =180.25,183.41,all P ＜0.05) increased,and the differences were sig nificant.(3) The expressions of Notch1,Jagged1 mRNA were positively correlated with TGF-β1 mRNA (r =0.84,1.00,all P ＜ 0.05),but negatively correlated with podocin mRNA (r =-0.95,-0.94,all P ＜ 0.05) in model group.Conclusions ATRA might alleviate podocyte injury through cutting the expressions of TGF-β1,Notch1,Jagged1 and raising the expression of podocin in injured podocytes induced by ADR.

Objective To establish a method of gas chromatography with head-space sampling for determination of five residual solvents ( acetone, ethyl acetate, isopropanol, dichloromethane, acetonitrile ) in raw material drug of cefotiam hexetil hydrochloride. Methods Agilent DB-624 capillary column(30 m×0.53 mm,3.0 μm)was used,with FID served as detector and DMF as the solvent. Results Linear relationships were obtained for the 5 residual solvents in their respective concentration ranges ( r=0.999 6-0.999 9,n=5) ,and the detection range was from 0.071 to 0.847μg. The stabilities measured as relative standard deviations ( RSD) for the 5 residual solvents were from 0.40% to 2.12% ( n=3) . The average recovery rates were 99.03% to 103.33%,and RSD were 0.54% to 3.41% ( n=3) . Conclusion The method is simple,sensitive and accurate for the residual solvent analysis in raw material drug of cefotiam hexetil hydrochloride.
