Objective Increased renal mast cells have been found in significant correlation with clinicopathological features of diabetic nephropathy ( DN) .However, the exact pathological significance of mast cells still remained to be elucidated.As one of the most abundant serine proteases, tryptase is specifically expressed by mast cells.The study was to observe the expression of tryptase in the urine of patients with diabetic nephropathy and realize the pathological significance of urinary tryptase and renal mast cells in the development of diabetic nephropathy. Methods Urine samples from 103 patients with diabetic nephropathy who were hospitalized at the clinical unit of the nephrology centre of Jingling Hospital from January 2012 to June 2013 were collected.According to concentra-tion of urinary albumin excretion rate, the patients were conducted to early-stage DN group (microalbuminuria,n=10), middle-stage DN group (proteinuria stage, n=31) and end-stage DN group (renal insufficiency stage,n=62).Meanwhile, urine samples from 20 normal persons were taken as the normal control group.Tryptase level in each urine sample was measured by using an ELISA kit.The average tryptase levels were compared among different groups and the correlation between urinary tryptase level and clinical indices was analyzed. Results ①In most cases, tryptase was not detected in the urine samples from normal persons(0.7 ±1.4 ng/mg creati-nine).However, the urinary trypatse level increased significantly with the development of diabetic nephropathy (11.6 ±10.5 ng/mg creatinine for early stage, 29.7 ±19.2 ng/mg creatinine for middle stage, and 44.6 ±43.4 ng/mg creatinine for late stage group).②The urinary tryptase level was found in significant correlation with ser-um creatinine (r=0.325, P<0.01), serum cystatin C (r=0.391, P<0.01), serum urea nitrogen (r=0.27, P<0.01), 24 hour uri-nary protein (r=0.389, P<0.01), urine C3 (r=0.276, P<0.05), urine retinol-binding protein (r=0.365, P<0.01), urine lysozyme (r=0.461, P<0.01), urine N-acetyl-β-glucosaminidase level (r=0.568, P<0.01), urinary kidney injury molecule-1 (r=0.434, P<0.05) and interleukin-18 level (r=0.375, P<0.05).No significant correlation was found between urinary tryptase level and age, gender, fasting blood sugar, postprandial blood sugar, HbA1c, triglyceride, high density lipoprotein or low density lipo-protein. Conclusion Mast cells play an important role in the development of diabetic nephropathy and might be a novel and effective target for the treatment of DN.

Objective To study the effect of glucocorticoid on serum interleukin(IL)-1,IL-6,transforming growth factor-?_1(TGF-?_1) and tumor necrosis factor alpha(TNF-?) in children with primary nephrotic syndrome(PNS).Methods The levels of cytokines on serum were compared in 3 different patho-type,and IL-1,IL-6,TGF-?_1 and TNF-? in serum were detected using enzyme-linked immunosorbent assay(ELISA) in 25 children with PNS before and after treatment with glucocorticoids.Results Significant difference of IL-1,IL-6,TGF-?_1 and TNF-? were found between the two group before and after the treatment(P0.05).The level of TGF-?_1 in MCD was lo-wer than that in MsPNG,FSGS before and after the treatment(P0.05),and the level of it in FSGS was higher than that in MsPNG after the treatment(P

OBJECTIVETo observe the curative effect of integrative medicine for treatment of systematic lupu erythematosus (SLE).

METHODSTotally 110 cases of SLE were randomized into two groups, 50 in the control group and 60 in the treated group, both were treated with prednisone, but to the treated group, integrative medica treatment was given additionally according to syndrome differentiation. The course for both groups was 6 months. Clinical symptoms, immunological indexes, peripheral blood figure, erythrocyte sedimentation rate (ESR), levels of C-reactive protein (CRP) and creatinine (Cr) in blood, and 24 h urinary total protein (u-TP/24 h) were observed before and after treatment.

RESULTSOf the 60 patients in the treated group, the treatment on 29 was evaluated as clinical remission, 18 as remarkably effective, 9 as effective, and 4 as ineffective, the total effective rate being 93.33% (56/60), while that in the control group was clinical remission in 11, remarkably effective in 10, effective in 19, ineffective in 10 respectively, and the total effective rate 80% (40/50), the difference on total ef fective rate between the two groups was significant (chi2 = 4.36, P <0.05). Besides, the improvement in the treated group was superior to that in the control group in terms of clinical symptoms such as fever, arthralgia and baldness (P <0.05, P <0.01); the negative reversion rate of anti-nuclear antibody (ANA, 51.3% vs 28.1%), antidouble-stranded DNA (ds-DNA, 53.6% vs 26.1%), anti- ribonucleoprotein (RNP, 63.2% vs 29.4%) and circulating immnue complexes (CIC, 63.2% vs 29.4%, all P <0.05); lowering of immunoglobulin (for IgG, P < 0.05; IgA, P <0.01; IgM, P <0.01); as well as bettering in peripheral blood figure, ESR, CRP, Cr and u-TP/24 h (P <0.05 or P <0.01).

CONCLUSIONIntegrative medical treatment is obviously effective for SLE patients.

Objective To estimate the present salt iodine content and iodine nutrition need of high risk population of iodine deficiency disorder in Meixian County. Methods Each primary school was selected from urban and rural areas(Xiyang Town, 20 kilometers away from Meixian County), the goiter rate of 8 to 10 year-old students was examined and urinary iodine and household salt iodine was sampled. Twenty to 40 year-old women of childbearing age nearby schools around the urban and villages around Xiyang Town were selected to collect their urine and salt samples. At urban hospitals and rural health centers, 0 to 2 year-old infant urine samples were collected, Thyroid gland was palpated and urinary iodine was determined by iodine in urine by As3+-Ce4+catalytic spectrophotometry, salt iodine was determined by direct titration. Results The goiter rates of 8 to 10 year-old students were 1.5 % (3/200), 1.0% (1/100) for the urban area and 2.0% (2/100) for rural area. Median of urinary iodine in 8 to 10 year-old students, infants, women of childbearing age averaged at 237.1 μg/L and 280.1, 234.7,187.6 μg/L respectively, with each being 287.4,245.0,205.5 μg/L in urban area and 278.9,228.5,176.4 μg/L in rural area. Women of childbearing age had a higher percentage of urinary iodine < 50.0 μg/L than students,students had a higher percentage than infants, each being 7.5%(15/200), 4.5%(9/200), 4.0%(4/100). The ration of urinary iodine > 300.0 μg/L was more in infants than in students, that in students was more than that in women of childbearing age, each being 33.0% (33/100), 30.0% (60/200),22.5% (45/200). The median of salt iodine was 27.2 mg/kg. The coverage of iodized salt was 100.0%(400/400). Ninty-seven percent(194/200) and 96.0% (192/200) of qualified iodized salt were consumed in urban area and in rural area. Conclusions The amount of iodine added to salt meets the requirement in the 3 kinds population risk of iodine deficiency disorder. But a higher iodine status has been found out in students and infants. It is reasonable to decrease the present salt iodine content.

In this paper, we expatiate the advance of Tricholoma matsutake including distributing, environment, pure culture, domesticating cultivation and artificial forcing breeding in the area of Changbai Mountain of China.

Growth patterns of trichome and contaminative bacteria in Spirulina sp. liquid culture were observed, and it was found that the number of neutral and alkalophilic bacteria was always 105～106 times of that of Spirulina sp. trichome. It would be very difficult to get real pure Spirulina sp. strain by classical methods of dilution plate, capillary and single trichome selecting methods. A great deal of contaminative bacteria was washed out by two pretreatment processes. Low speed centrifugation was designed to wash the strains which usually deposit at bottom, and filtration method was designed to treat the strains usually floating at surface. Sandwich plate and dilution plate were designed for the purification of the mobile strains and non-mobile strains, respectively. A lot of strains were purified by the above processes and pure single trichome formed pure colonies on plates.
