Henoch-Sch(o)nlein purpura(HSP) is one of the most common vasculitides in children with many manifestations including skin purpura,arthritis,abdominal pain and renal involvement.The renal involvement(Henoch-Sch(o)nlein purpura nephritis,HSPN) is the principal cause of morbidity and major risk factor for prognosis in HSP.The paper reviewed the updated treatment strategy for HSPN.Accordingly,steroids,cyclophosphamide,mycophenolate mofetil,mizoribine,cyclosporine,triptolide,angiotensin converting enzyme inhibitors (ACEI) / angiotensin receptor blockers(ARB),plasma apheresis and tonsillectomy are possible indicator for the further therapy of HSPN.Furthermore,prospective randomized controlled treatment studies on children with severe HSPN would be needed.

[Objective] This article mainly discussed the potential of myocardial cellregeneration and the possible mechanisms involved. [Method] To study the mechanism of cardiac regeneration ability HSCs, this review studyed the relationship of the differentiation of cardiac stem cells, hematopoietic stem cells, myocardial cells and myocardial regeneration and the possible mechanisms involved. [Result] Self-renewing, differentiation both in vitro and in vivo of the c-kit positive CSCs had been seen. No matter in physiological condition or after damage, the c-kit positive CSCs had clonality and the potential of multi-directional differentiation. Hematopoietic stem cells can generate cardiomyocytes and coronary blood vessels for human celltherapy. The ability of dedifferentiation cells to maintain and improve the ventricular function of a damaged heart is very limited. [Conclusion] CSCs and HSCs play an important role in reversing chronic ischemic and non-ischemic heart failure.

Objective: To analyze the constitution of hospitalization expenses and provide evidence for controlling unreasonable increase of medical costs. Methods: To compare the medical expense constitution of cerebral infarction patients with and without medical insurance; interview the doctors, patients and the medical insurance managers of medical insurance, analyze the influencing factors of the expense through combining the result of interview and quantitative data. Results: The patients with medical insurance spent higher expense than their counterparts, the per capita cost of medical insurance increase by year. Through analyzing the constitution of hospitalization cost, medicine fee and examination cost are the major medical costs. Conclusion: The costs of patients with medical insurance have over-treatment problem, which could be controlled by changing payment method and strengthening management.

Objective To investigate the effect of c-myc ASODN on the proliferation and invasion of human bile duct carcinoma cell line QBC939. Methods QBC939 cells was conventionally cultured. C-myc ASODN was designed and transfected into QBC939 cell line. MTT assay and transwell experiment were used to study cell proliferation and invasion of QBC939 cells. Results MTT assay showed that cell survival rate in ASODN group was significantly lower than that in blank group(P < 0.05). Transwell experiment showed that the num-ber of cells penetrated in ASODN group was significantly lower than that in blank group(P<0.01). The cell survival rate and the number of cells penetrated in vechicle group had no difference with blank comparison group(P>0.05). Conclusions C- myc ASODN can inhibit the proliferation and invasion of QBC939 cells.

Among of 8 benign lung disease patients,there is just CK20mRNA was detected in one patient,both CEAmRNA and CK19mRNA were not detected in their peripheral blood. As for those 30 healthy volunteers,there is none of the mRNA was detected. Moreover,there is a marked positive correlation between the levels of CEAmRNA,CK19mRNA and CK20mRNA,the levels of CEAmRNA,CK19mRNA and CK20mRNA were correlated to the physiological cause or degree of lung cancer.Conclusion CEAmRNA,CK19mRNA and CK20mRNA in peripheral blood can be as auxiliary index for diagnosing lung cancer micrometastasis,also can monitor the lung cancer micrometastasis by quantity it.

Objective To investigate the epidemiological characteristics of children infected by mycoplasma pneumoniae(MP)over the last five years in Kunming region.Methods Indirect immunofluorescence assay was used to detect blood MP-IgM of hospitalized patients from January 2003 to December 2007 in order to determine the age and gender distribution characteristics of MP infection and to investigate the epidemiological features of the five years' results.Results Infection incidences by MP in Kunming region over the last five years were 20.9%,14.3%,17.5%,15.7%and 19.5%,respectively.Statistical significance was found among the groups mentioned above(P＜0.01).The MP infection incidences in different age groups were 10.7%(～1 year old),20.5%(～3 years' old),21.5%(～6 years' old)and 21.7%(～14 years' old).MP infection incidences showed age and gender characteristics(P＜0.01).Infants showed lower NIP infection incidence and infection incidence was higher in female.The epidemiological investigation indicated that MP infection incidences varied from year to year(P＜0.01).The infection incidences of 2003 and 2007 by MP were higher than those of the other years.There were epidemiological differences in infection incidences by NIP over last five years(summer,autumn and winter).The MP infection incidences showed seasonal differences(P＜0.01).Conclusion Mycoplasma pneumoniae was the main local causative agent responsible for respiratory tract infection in children aged under one years' old in Kunming region.Over the last five years,there were two outbreaks in the local area,but with no seasonal regularity of epidemiology.

Background and purpose:Visceral pleural invasion (VPI) and vessel invasion (VI) are poor prognostic factors in patients with non-small cell lung cancer (NSCLC). The primary initial recurrence site may be local recurrence in VPI and distant metastasis in VI. The purpose of this study was to validate the prognostic impact and effect of the initial recurrence site of VPI and VI on survival outcomes for NSCLC.Methods:Two hundred and ninety patients who were diagnosed as having NSCLC and underwent lobectomy between Jan. 2007 and Dec. 2013 were retrospectively analyzed. VPI was identiifed in 51 patients as VPI group, the other 239 patients without VPI as non-VPI group. VI was identiifed in 29 patients as VI group, the other 261 patients without VI as non-VI group. Clinical characteristics, overall survival (OS), disease-free survival (DFS) were compared.Results:There were statistically signiifcant differences between VPI group and non-VPI group in tumor size, lymph node metastasis, TNM stage and initial recurrence site (P<0.05). Furthermore, there were statistically signiifcant differences between VI group and non-VI group in lymph node metastasis and TNM stage (P<0.05). The 1-, 3- and 5-year OS rates in VPI group (88.2%, 56.7% and 52.7%) were lower than those in non-VPI group (95.8%, 83.7% and 74.0%,P<0.001). The 1-, 3- and 5-year OS rates in VI group (79.3%, 56.8% and 48.7%) were lower than those in non-VI group (96.1%, 81.3% and
72.3%,P=0.001). Cox regression showed TNM stage was a significant prognostic factor for DFS, whereas lymph node metastasis and VPI were signiifcant prognostic factors in patients with NSCLC.Conclusion:The primary initial recurrence site in VPI patients is local recurrence. Patients with VPI or VI may need more postoperative therapy because of their poor prognosis.

Objective To investigate the application of selective hepatopetal blood occlusion techniques in anatomic hepatectomy.Methods We retrospectively reviewed the clinical data of 259 patients with hepatolithiasis or liver tumor undergoing anatomic hepatectomy under selective hepatopetal blood occlusion from January 2006 to December 2009.Results Totally,183 cases with hepatolithiasis and 76 cases with liver tumor underwent anatomic hepatectomy under selective hepatopetal blood occlusion.The average intra-operation blood loss was 210 mL(120-1 600 mL);post-operation incidence of complications and the rate of residual stones was 10.9% and 4.2%,respectively.Thre was no operative death in this series.The intrahepatic recurrence and metastasis rate of liver tumor was 23.6% and the median recurrence was 16.3 months.Conclusions The use of a appropriate selective hepatopetal blood occlusion during anatomic hepatectomy for hepatolithiasis and liver tumors is an effective measure to reduce surgical complications and improve outcome.
