Objective To investigate and analyze the dwarf reasons for children in the area of Huai'an city,Jiangsu province.Methods A retrospective analysis of 92 cases of children with short stature in our hospital in recent 5 years had been made.Results The dwarf reasons for the 92 cases of undersized children were:lack of growth hormone (53.3％),physical sexual puberty delay (16.3％),hypothyroidism (9.8％),turner syndrome (7.6％),nanosoma essentialis (5.4％),familial short stature (4.3％),intrauterine growth retardation (2.2％)and glycogen storage disease type Ⅰ (1.1％).Conclusion The main dwarf reasons for children were growth hormone deficiency and physical sexual puberty delay,and medical treatment should be used as soon as possible.

ObjectiveTo report the first laboratory-confirmed human monocytic ehrlichiosis (HME) case in Shandong Province.MethodsThe epidemiological investigation was done by filling out questionaires.Blood sample was collected for detecting the specific 16S rRNA gene of Anaplasma phagocytophilumandEhrlichiachaffeensisbynested-polymerasechainreaction(PCR).ResultsThis case was characterized by acute onset of fever,leukopenia and thrombocytopenia.The specific 16S rRNA gene of Anaplasma phagocytophilum was negative and the specific 16S rRNA gene of Ehrlichia chaffeensis was positive by nested PCR test.The PCR product was sequenced.The homology was above 99 ％ between the acquired nucleotide acid sequence and the Ehrlichia chaffeensis sequences registered in GenBank.ConclusionThe Ehrlichia chaffeensis infection exists in Shandong Province,which warrants further research on these natural loci of HME in this area.

Aim To investigate the effect of flavonoids from Prinsepia utilis Royle( FPR) on the histomorphol-ogy of kidney in diabetic mice, and to investigate its protective mechanism. Methods Diabetic mice in-duced by alloxan were given FPR orally each day for four weeks. After the administration for two and four weeks, ten mice in each group were randomly sacri-ficed. The kidneys were removed and weighed. The extracted renal tissue was embedded with paraffin and sectioned, the sections were stained with Hematoxylin and Eosin(HE)、Periodic acid Schiff(PAS) and Go-mori, and then observed under the microscopy. 1mm3 of renal cortex fixed with glutaral in four centi-degree , and then the ultrastructure of each group was observed under the electron microscope respectively after four weeks′ treatment. Results Compared with the model control group, in the treatment group, observation un-der the microscopy showed that glomerular volume and mesangial cells reduced, FPR could relieve thickening of the glomerular basement membrane ( GBM ) , little inflammatory cells infiltrated in the interstitium,tubular epithelial cells almost became normal, renal tubule had little glucogen, fiber decreased in the interstitium of renal tubule. Observation under the electron micro-scope indicated that foot process in podocytes lined up in order, mitochondria of the renal tubule’ s epithelial cell almost recovered. Conclusion FPR can relieve the changes of renal pathology,improve renal function, and delay the progression of pathologic changes of kid-ney in diabetic mice partly through reducing the blood glucose and the blood lipid.
