Objective To compare the influence of general anesthesia and spinal anesthesia on the mortality in rats with fat embolism.Methods Three hundred and seventy five rats were randomly assigned to receive general anesthesia （group GF,n=125）,spinal anesthesia （group SF,n=125）,or no anesthesia （group F,n=125）.Rats were injected with a half lethal dose of fat from caudal vein 20 min after anesthesia induction. The mortality was recorded at 2,8,12,and 24 h after fat injection,respectively.Results The mortality was lower in group GF than those in groups SF and F （P0.05）,while there was no statistical difference between group SF and group F.Conclusion The mortality in rats with fat embolism under general anesthesia was lower than that under spinal anesthesia.

Objective To study the expression of BCSG1 ,S100A4,VEGF in human breast cancer.Methods Immunohistochemistry technique SP method was used to examine breast fibroadenoma in 40 cases,breast invasive ductal carcinoma in 62 cases ( by armpit lymph node metastasis as 2 groups) and corresponding paratumor tissues in 48 cases. Results Among the 4 groups, there was significant difference ( P＜0.05 ) in the positive immunostaining rate of BCSG1 ,S100A4, VEGF. Conclusions In the breast invasive ductal carcinoma, the expression of BCSG1, S100A4 and VEGF increased. This suggested the invasive and metastasis ability of the neoplasm enhanced. The expression were in positive correlation with tumor pathology. Combined detection of BCSG1, S100A4, VEGF expression contributes to the early diagnosis and prognostic assessment of the carcinoma of the breast.

Objective To investigate the prevalence of malnutrition in human immunodeficiency virus ( HIV )‐infected children in China , and to explore and analyze the factors associated with malnutrition .Methods A cross‐sectional study was conducted by the antiretroviral treatment database of children .HIV‐infected children aged between 0 - 15 years old who initiated antiretroviral treatment were collected between January 1st , 2010 and December 31st , 2014 . Z‐score of height and weight were calculated by WHO Anthro (plus) software .Univariate and multivariate Logistic model analyses were performed to determine the factors associated with acute /chronic/mixed malnutrition .Results Baseline data of the 3 138 HIV‐infected children showed that 1 645 patients (52 .42% ) had malnutrition before antiretroviral treatment ,with acute ,chronic and mixed malnutrition of 8 .76% (275) ,39 .77% (1 248) and 3 .89% (122) ,respectively according to the type of malnutrition .Multivariate analysis showed that baseline CD4 + cell count < 200 cells/μL was the risk factor associated with acute malnutrition (aOR =2 .27 ,95% CI :1 .68 - 3 .06) ;rural settings (aOR = 1 .30 ,95% CI :1 .11 - 1 .53) ,baseline CD4 + cell count < 200 cells/μL (aOR = 1 .98 ,95% CI :1 .65 - 2 .38) ,baseline CD4 + cell count between 200 to 350 cells/μL (aOR = 1 .38 ,95% CI :1 .13 - 1 .69) and having AIDS‐related diseases (aOR = 1 .34 ,95%CI :1 .13 - 1 .59) were risk factors associated with chronic malnutrition ;and age of 11 - 15 years (aOR =2 .38 ,95% CI :1 .46 - 3 .88) ,baseline CD4 + cell count < 200 cells/μL (aOR = 4 .99 ,95% CI :3 .04 -8 .21) and having AIDS‐related diseases (aOR = 2 .45 ,95% CI :1 .65 - 3 .66) were risk factors associated with mixed malnutrition .Conclusions The prevalence of malnutrition in untreated HIV‐infected children remains high .All three types of malnutrition are associated with immunodeficiency .Early diagnosis and early treatment should be improved in HIV‐infected children through antiviral therapy to reduce the destruction of HIV to immune system .At the same time ,intensified monitoring of the nutritional status and nourishing undernourished children should be strengthened to reduce the prevalence of malnutrition .

OBJECTIVEThe spectral imaging method was used to quickly identify the Cortex Dictamni pieces and its counterfeit alangium Chinese, which is a potential method would be applied to control the quality of the Cortex Dictamni pieces.

METHODStandard sample, 5 cortex dictamni samples and its counterfeit alangium Chinese of different sources were tested by the liquid crystal imaging instrument.

C1q nephropathy is a special type of glomerulonephritis, which characterized by massive deposition of C1q on glomerular mesangial.The pathological manifestations of C1q nephropathy are minimal change disease, focal segmental glomerulosclerosis and proliferative glomerulonephritis.C1q nephropathy is prone to hormone dependence or resistance, and the prognosis is not good relatively.The pathogenesis of the disease is not clear.The clinical manifestations are quite different.Glucocorticoid is still the first choice for treatment.Immunosuppressive agents are often used in patients with hormone dependence or resistance.It has been found that the rituximab has good curative effect on C1q nephropathy in recent years.Although the understanding and research on C1q nephropathy is deepening, there is still much controversy about whether to classify C1q nephropathy into a class of independent diseases and the clinical significance of their classification.In this paper, the pathogenesis, pathological histology, clinical characteristics, treatment and prognosis of C1q nephropathy are reviewed in order to have a better understanding of C1q nephropathy.

Nephrotic syndrome is a clinical syndrome characterized by massive proteinuria, serum hypoalbuminemia, edema, hyperlipidemia.Most children can get relief with hormone therapy, but 15%~20% of children with hormone resistance eventually reach to end-stage nephropathy.Genes associated with steroid resistant nephrotic syndrome(SRNS)include NPHS1, NPHS2, CD2AP, TRPC6 encoding the slit diaphragm of podocytes, ACTN4 and INF2 encoding podocyte cytoskeleton proteins, WT1 encoding the nucleus of podocytes, COQ2 and COQ6 encoding mitochondrial proteins of podocytes, LAMB2 encoding glomerular basement membrane proteins.Research have found that one mutation in one of these molecules is enough to cause SRNS, so SRNS is also known as podocyte molecular disease.
