AIM: To investigate therapeutic effects of recombinant human growth hormone(rhGH) on rat sepsis and its possible mechanisms. METHODS: Mean arterial pressure (MAP), levels of plasma TNF?,IL-1? and endotoxin,leukocyte count and survival rate within 1 week were determined after E. coli injection among control group,sepsis group and sepsis+rhGH group. RESULTS: (1)rhGH diminished the decrease of MAP, reduced plasma endotoxin and TNF? levels and increased neutrophil ratio in total leukocytes in sepsis rat. rhGH increased survival rate within 1 week on sepsis rat. (2)No changes were found in IL-1? level among the three groups. CONCLUSION: rhGH showed desirable beneficial effects on rat sepsis, which may attribute to: improving circulatory function; maintaining intestinal mucosa barrier, attenuating bacteria/endotoxin translocation and inhibiting the production and release of TNF?.

Objective To study the relation between phlegm-damp retention type of metabolism syndrome and microcosmic indices in order to find out the objective evidence for TCM syndrome differentiation.Methods Totally 49 cases of metabolism syndrome were observed,25 of them were phlegm-damp retention type in differentiation and 24 were non-phlegm-damp retention type.The height, body weight,waistline and blood pressure of two groups were measured,the serum leptin,insulin and blood lipid were determined, and the insulin resistance index(IRI)and body mass index(BMI)were calculated.Results The leptin,BMI,systolic pressure,FINS and IRI of the phlegm-damp retention group were all higher than those of the non-phlegm-damp retention group.Conclusion BMI, leptin,insulin,and IRI may be taken as the the index of syndrome differentiation in metabolism syndrome.

Plasma exchange is a commonly used blood purification method, h includes plasma exchange,double filtration plasmapheresis and immunoadsorption.Many nervous system diseases have the antibody. Guillian-Barre syndrome is caused by antibodies of the nervous system demyelinafing disease; Myasthenia grads is caused by the acetylcholinc receptor antibodies. CIDP also has autoimmune-mediated mechanism. Plasma exchange can be apphed effectively to remove antibodies, and to quickly improve the patient' s clinical symptoms and shorten the course of disease.

Objective To investigate the characteristics of Wegener granulomatosis in children and to improve its recognition. Methods Ten pediatric patients with Wegener granulomatosis were studied retrospectively by clinical manifestations, serum examination, pathological data, treatment, etc. Results All children had clinical evidence of upper respiratory tract and lungs involvement; kidney lesion occurred in 6 cases(6/10); joints, skin, eyes and nervous system were also involved with different degree, cANCA (PR3) showed positive in 8 cases; Pathological examination (1 kidney sample, 2 nasal mucosa samples, 2 skin samples) showed granulomatous vasculitis and crescents were found in renal biopsy; 7 cases were treated with corticosteroid plus cyclophosphamide, 1 case was treated with corticosteroid plus methotrexate, and improvement were seen in all of them. Conclusions Wegener granulomatosis in children have diverse clinical manifestations and clinical diagnosis is difficult. The upper and lower respiratory tract and kidney are most commonly involved organs. ANCA inspection is characteristic. Treatment with corticosteroid and immunosuppressive can achieve good outcome.

Objective To analyze the clinical and radiographic characterstics of ureteral polyps with hydronephrosis in children.Methods Thirteen patients with ureteral polyps and hydronephrosis were studied retrospectively.All patients underwent abdominal plain film,intravenous pyelogram(IVP)and ultrasound(US)examinations,contrast-enhanced CT scan was performed in 10 cases.Results Intermittent or recurrent abdominal pain with painless hematuria was presented in most cases.Hydronephrosis was demonstrated in radiographic images.IVP delineated the dilatation of the ureter and filling defects within the ureteral lumen in 5 cases.Computed tomography(CT)showed all abnormal changes of ureter and irregular intraluminal soft tissue masses in 6 cases.Moderate and low echoic structures were showed in ureters by US in 2 cases.Conclusion US and CT,as an important imaging modalities,can improve the diagnostic accuracy for ureteral polyps.

Two Pseudomonas strains, K80 - B and K80 - A, can use hydrocarbon as carbon source by two different mechanisms. Different effects can be observed when they are applied to 69-8 oil of Dagan Oil Field. The strain K80-B producing both hydrocarbon pseudosolubilizing factor and hydrocarbon emulsifying factor can decrease the viscosity and solidifying point of the 69-8 oil 51.6% and 2℃ respectively. Whereas the other can only decrease 43.5% and 3℃ respectively. When the two strains are mixed, synergistic effect on crude oil is obvious.

Objective To investigate the expression and significance of Smad 7,Smurf 1 and Smurf 2 in basal cell carcinoma and squamous cell carcinoma.Methods Biopsy specimens were resected from 14 patients with basal cell carcinoma,19 patients with squamous cell carcinoma and 30 normal controls.Quanti- tative real-time PCR and immunohistochemical techniques were utilized to assess the expression of Smad 7, Smurf 1 and Smurf 2 in these specimens.Results The gray scale for staining of Smad 7,Smurf 1 and Smurf 2 was 166.61?7.11,166.08?8.71,and 166.25?8.15 respectively in basal cell carcinoma,161.66?5.52,166.84?9.27,and 169.98?9.48 respectively in squamous cell carcinoma.The expression levels of Smad 7,Smurf 1 and Smurf 2 were all significantly increased in basal cell carcinoma and squamous cell car- cinoma in comparison with normal controls.Conclusions The over-expression of Smad 7,Smurf 1 and Smurf 2 may interfere with transforming growth factor?signaling transduction pathway through several links,therefore prevent the inhibitory effect of transforming growth factor?on epidermal proliferation,and accelerate the abnormal proliferation in above epidermal tumors.

High glucose stimulated angiotensinⅡ(ATⅡ) production in mesangial cells of rat.Both high glucose and ATⅡdecreased expressions of matrix metalloprotein-9 (MMP-9) mRNA and MMP-9/tissue inhibitor of metalloproteinase-1 (TIMP-1) mRNA ratio and increased TIMP-1 mRNA expression in mesangial cells of rat,which could be reversed by an ATⅡreceptor blocker,Saralasin.
