Viral encephalitis is infectious diseases caused by many kinds virus which infects the brain and produces a series of clinical manifestations,it is an common disease in children.Rhabdomyolysis is a sort of syndrome characterized by striated muscle necrosis and the release of intracellular muscle constituents into the circulation,most notably high level of creatine phosphokinase and myoglobin,and myoglobi-nuria,which is often complicated with acute renal failure.It was reported that rhabdomyolysis could be associated with many viral encephalidities,the clinician should pay attention to this condition because it was not rare especially,when hematuria appearred in the course of viral encephalidities,serum creatine phosphate kinase,serum and urine myohemoglobin should be detected to identify whether rhabdomyolysis was existed.Once the diagnosis was confirmed,it should be treated with fluid administration and basification in order to avoid acute renal failure,and to improve prognosis on these patients.This study reviewed the literature on viral encephalidities and rhabdomyolysis.

Objective To observe the central nervous system(CNS)damage in children with mycoplasma pneumoniae pneumonia(MPP)and explore its mechanism.Methods A total of 325 cases of MPP were selected to investigate the incidence of CNS damage,and the levels of IL-8,IL-18 and soluble interleukin-2 receptor(sIL-2R)in both serum and cerebrospinal fluid(CSF)were detected in those patients with CNS complications.Children with viral encephalitis at hospital during the same period were taken as control group.Use SPSS 12.0 software to analyze the data.Results There were 22 cases(6.8%)of MPP who had CNS complications,presented mainly with fever,vomiting,headache and convulsion.The levels of IL-8,IL-18 and sIL-2R were higher in MPP patients who had CNS complications than those in control group,especially the level of IL-18 and sIL-2R in CSF(Pa

Objective To evaluate the application value of the blood culture combined with the detection of serum procalcitonin and C-reactive protein(CRP)in diagnosing infectious fever patients.Methods The PCT and CRP detection results on the blood sampling day in 126 cases of fever with positive blood culture and 123 cases of fever with negative blood culture in the emergency department were retrospectively analyzed,and the two sets of data were compared and statistically analyzed by the SPSS 16.0 soft-ware.Results The positive rates of CRP and PCT in 126 cases of positive blood culture were 100% and 100%,the detection values were 26.9-256.8 and 0.25-98.6,the positive rates of CRP and PCT in 123 cases of negative blood culture 95.5% and 15.4% re-spectively,the detection values were 1 .2-126.8 and 0.02-0.98.The PCT and CRP detection values in the positive blood culture group were significantly higher than those in the negative blood culture group,the difference was statistically significant(P <0.01). Conclusion PCT and CRP can be served as the monitoring indicators for blood bacterial infections,the blood culture combined with PCT and CRP detection has the guidance significance for early diagnosing bacterial infection.

Aim To observe the change of NF-?B and expression of Bax and Bcl-2 related to apoptosis regulation in the cerebral infarction rat and study the protective effect of iridoid glycoside(IG) extracted from cornus officinalis on focal cerebral ischemia injury and its mechanism of action.Methods Rats were pretreated with drugs by mouth for 7 d and a focal cerebral infarction model of rat was induced by photochemical reaction.Immunohistochemistry and western blot were used to detect the change of expression of NF-?B,Bax and Bcl-2 in the cortex.Results Compared with control group,expression of NF-?B and Bax were increased while expression of Bcl-2 was decreased.Compared with model group,IG(IG 20、60、180 mg?kg~(-1)) markedly decreased the expression of NF-?B and Bax and increased expression of Bcl-2.Conclusion IG has therapeutical effect on cerebral infarction through regulating the expression of NF-?B and apoptosis related genes

Objective To improve the understanding and diagnosis of primary hypertrophic os-teoathropathy(PHO).Methods A case of PHO was reported.The clinical data and the process of the diagno-sis and treatment was analyzed retrospectively,and the related literature were reviewed.Results The patient was a young man without family history of PHO.He had symptoms since age 16.He had clubbing fingers and toes,hypertrophic skin,joint swelling,hyperhidrosis and radiographic evidence of periostitis.Thus the disease was diagnosed as PHO.The patient was treated with NSAIDs and the symptoms relieved very quickly.Conclusion Radiographic examination should be taken in time when young males have the general characters of clubbing fingers and toes,hypertrophic skin changes.If the periostitis presents,the final diagnosis of PHO can be confirmed.

ObjectiveTo investigate the effect of all-trans retinoic acid (atRA) on the renin-angiotensin system (RAS) in 5/6 renal ablation model. MethodsAtRA was administered to 5/6 renal ablation rats by three dosages: 5 mg·kg-1·d-1 (n=8), 10 mg·kg-1d-1 (n=8) and 20 mg·kg-1 d-1 (n=8) and vehicle (vehicle group, n=8) for 10 weeks. Healthy rats consisted of shamoperation group (n =8). The level of renin and angiotensin Ⅱ in renal tissues were measured by radioimmunoassary. The level of angiotensin type 1 receptor (AT1R) in remnant renal cortex was measured by Western blot. The mRNA expression levels of two subunits of activative protein 1(AP-1),c-jun and c-fos was quantitated by real-time PCR. ResultsAfter 10 weeks of atRA treatment by gavarge, artery blood pressure decreased (P＜0.05). AtRA reduced the levels of renin (P＜0.05) and angiotensin Ⅱ (P＜0.05) in kidney and down-regulated the expression of AT1R protein in renal cortex. Larger dose of atRA (20 mg·kg-1·d-1) performed higher activity in inhibiting renin and AT1R. Compared with vehicle group, atRA could significantly inhibit the expression of renal c-jun and c-fos mRNA (P＜0.05). Conclusion atRA can decrease the over-expression of main components of RAS.

Objective To investigate the developmental characters of neural stem cells(NSCs) in occipital of cortex from human fetal brain at different age.Methods Ninety cases of embryoes at gestational age 16-32 weeks and by induction of labor with water bag were collected for determining distribution,shapes,growth modes and the number of NSCs in the occipital of cortex with immunohisto- chemical method under light microscope.Results It was noted that NSCs existed in the occipital of cortex from human fetal brain at different ages.NSCs mainly distributed in layers of cone cells and inner granule cells.NSCs existed in the occipital of cortex of different fetal age included middling round cells,NSCs had enations from 0 to 1.Nucli were larger than plasm.Each NSC had nucleoli from 2-4 and rarefaction chromatin.Most of NSCs distributed in three growth modes including crowd,cluster and clone,occasionally with a single growth mode among other nerve cells.There were no differences including distribution,shapes,growth modes and the number of NSCs in the occipital of cortex between groups,but,NSCs gradually decreased with increasing of age.Conclusion NSCs exists in the occipital of cortex from different gestational age,and the number of NSCs decreases with increasing of age.

Injectable bone tissue engineering scaffold material has a certain form and mechanical strength.It can be loaded with seed cells for injection to the defected site of bone tissue in the form of fluid.After that,structural recovery and functional reconstruction are achieved,and the new bone is formed ultimately.This material has the characteristics of small trauma and good plasticity.It can repair the irregular bone defects and well associate with growth factor,which is the ideal method for repairing bone tissue defects up to now.Among the various injectable bone tissue engineering materials,bioceramic materials,polymer materials,etc.have been proved to have a high biological compatibility and good mechanical properties.That makes these materials become the focus of current research in bone tissue engineering materials.In this paper,the development and application of bioceramic materials,polymer materials,bioceramics and polymer composites were reviewed.
