Objective To study the value of plasma level of matrix metalloproteinase-9 (MMP-9) for the early diagno-sis of Kawasaki disease. Methods The difference in MMP-9 level was studied by retrospective nested case-control method between children with early Kawasaki disease, Henoch-Sch?nlein purpura (HSP) or respiratory infection, and healthy control children. The associations of MMP-9 with serum procalcitonin, erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) were also analyzed. The cutoff-value, sensitivity and speciifcity of MMP-9, ESR and CRP in diagnosis of Kawasaki disease were studied by ROC curve. The areas under ROC curves were compared among different diagnostic markers to deter-mine their signiifcances in diagnosis of Kawasaki disease. Results The plasma level of MMP-9 was increased in early phase of Kawasaki disease, and higher than that in children with HSP or respiratory infections and in healthy controls (P<0.05). If MMP-9, ESR and CRP cutoff value were set to be 90.23 ng/ml, 56.5 mm/h and 27.55 mg/L, the sensitivity, speciifcity and area under ROC curve was 83.3%, 86.4%and 0.904, 95.8%, 66.1%and 0.807, 83.3%, 74.6%and 0.789 respectively. The diagnostic performance of MMP-9 for Kawasaki disease was better than that of ESR and CRP. Conclusions The plasma level of MMP-9 is increased in the early stage of Kawasaki disease. The sensitivity and speciifcity of MMP-9 in diagnosis of Kawasaki disease are highest if cutoff value is set to be 90.23 ng/ml.

Objective The clinical features of elderly patients with severe acute pancreatitis (SAP) were atypical and these patients were often misdiagnosed as having paralytic ileus. The clinical presentations of elderly patients with SAP whose first diagnosis as paralytic ileus were analyzed. Methods 18 patients of elderly SAP who were misdiagnosed as having paralytic ileus were included and the clinical data were compared with 58 elderly patients with SAP. Results Among the misdiagnosis group, the first symptom onset were fleus, abdominal distension, vomiting, constipation, abdominal pain, diarrhea for 5, 4, 3, 3, 2, 1 case, respectively. Among SAP group, the first symptoms onset were 2, 31, 9, 3, 11, 2 cases, respectively. For misdiagnosis group, 13 cases were correctly diagnosed by CT scan, 3 cases by ultrasound and 2 cases by serum amylase test. For SAP group, 32, 15, 11 cases were diagnosed by CT scan, ultrasound and serum amylase, respectively (P < 0.05). 4 and 13 patients died in misdiagnosis and SAP group, respectively; among these 13 patients, 10 were female and 3 were male. Conclusions The elderly patients with paralytic ileus should consider the possibility of SAP, and CT scan was valuable for correct diagnosis.

Objective To investigate the effect of pre- hospital emergency care programs in children with febrile seizures,in order to reduce damage by febrile seizures and obtain the best firstaid effect. Methods 112 cases of children with febrile seizures were treated in pediatric department of our hospital from April 2009 to February 2011.The parents of 75 children patients were given guidance of prehospital emergency care,they were set as the pre-hospital emergency care group.The other 37 cases were set as the non-pre-hospital emergency care group,routine emergency care was given until the medical personnel arrived at the spot.The conditions of aspiration,tongue bite injury,another episode of febrile seizures and brain damage were recorded in two groups of children. Results Only one case of aspiration and three cases of febrile seizures occurred in the pre-hospital emergency care group by misoperation of parents.Non brain damage and tongue bite injury occurred.The incidence rate of improper consequences was 5.3％in the pre-hospital emergency care group,lower than that of the non-pre-hospital emergency care group,51.4％. Conclusions To give pre-hospital emergency care guidance to parents of children patients by mobile phones before the health care workers reach the spot can significantly reduce accidental injury of children,stabilize the emotion of parents,decrease the impact of seizures on children,all the above has a positive effect on follow-up treatment.

Objective To establish the HepG2 cell lines which can stably express and replicate hepatitis 13 virus (HBV).Methods One point two X unit length of HBV genome was cloned intn SalⅠsite of the eukaryotic expression vector pREP10 to construct the recombinant plasmid pREP-HBV. Human hepatoblastoma cell HepG2 was transfected with pREP-HBV by Lipofectamine 2000 and seh,cted by bygromycin at the concentration of 250?g/mL.HBsAg and HBeAg were monitored by enzyme linked immunosorbent assay (ELISA)kits.H13V particles presemed in supernatant were ex- amincd by electronic microscopy.DNA isolated from intracellular HBV core particles was analyzed by Southbern blot using HBV-specific probe.Results The recombinant vector pREP HBV containing 1.2?unit length of HBV DNA was constructed successfully.After transfection of pREP-HBV to HepG2 cells and consistently cultured in hygromycin selective medium.5 drug-resistant cell lines, RHBV1-RHBV5.were established,and all of them could stably express HBsAgand HBeAg.South ern blot analysis revealed that HBV could replicate in all cell lines,as confirmed by the presence of replicateintermediatc DNA in intracellular HBV core particles.Clustered 42 nm Dane particles as well as 22-26 nm spherical H13sAg particles in condensed cuhure supernatant were visualized by elec tronic microsopic analysis.Conclusion HepG2 ceil lines in which HBV can replicate and express specific antigens are successfully established.Up to now,the cells have been passaged every three days for 50 times.

Apoptosis refers to the programmed death process of cells modulated by genes. It plays an important role in promoting the evolution of organisms, regulating the development of multiple systems, and maintaining the stability of internal environment. The major apoptosis pathways include mitochondrial pathways, death receptor pathways, and endoplasmic reticulum pathways. With the rapid development of the scientific research on acupuncture, it’s revealed that cell apoptosis should be closely related to the action of acupuncture. So far, the major apoptosis factors involved in relevant researches are P53, Bcl-2 family, Cyt-C, Caspase, Fas/Fasl, TNFR1/TNF-?, and FADD-Caspase8, and PERK, etc. Via influencing these apoptosis factors or genes, acupuncture can produce various effects in improving tissue ischemia, protecting neural cells, reducing inflammation, and correcting endocrine disorders. This article summarized and reviewed the apoptosis pathways and key factors related to the action of acupuncture, to provide some beneficial references for future studies.
