Objective To analyze the relationship between cystatin C(Cys C) and homocysteine(Hcy) in patients with early diabetic nephropathy.Methods48 cases of T2DM patients from June 2013 to December 2015 in our hospital for treatment were chosen as the observation group, including 30 patients with early diabetic nephropathy patients as the observation group 1, 18 cases of T2DM patients as the observation group 2, were selected in our hospital physical examination of 28 healthy persons as control group,serum Cys C and Hcy levels were measured at the same time, urinary albumin / creatinine ratio (Ualb/cr) was measured in the observation group, test results of three groups were analyzed and compared.ResultsThe serum Cys C and Hcy in the observation group were significantly higher than the control group, and Cys C and Hcy levels in observed 1 group were significantly higher than that observed in the 2 group, the difference was statistically significant in the observation group, serum Cys C and Hcy level was positively correlated with Ualb/cr.ConclusionThe relationship between Cys C and Hcy levels and early diabetic nephropathy has very important significance in the early diagnosis of diabetic nephropathy, can effectively improve the rate of diagnosis of early diabetic nephropathy patients.

Objective:To investigate the value of serum monocyte/high-density lipoprotein cholesterol ratio (MHR) and urinary albumin/creatinine ratio (ACR) in the evaluation of osteoporosis in diabetic nephropathy patients.Methods:Diabetic nephropathy patients treated in Hangzhou Ninth People’s Hospital from Jun. 2019 to Jun. 2022 were selected. Gender, age, height and weight of all patients were collected and recorded, and body mass index (BMI) was calculated. Blood calcium (Ca), blood phosphorus (P), parathyroid hormone (PTH), monocyte count (M), high density lipoprotein (HDL-C), urinary microalbumin and creatinine were measured and recorded in all patients. MHR and ACR were calculated, MHR=M/HDL-C, ACR=urinary microalbumin/creatinine. Lumbar spine bone mineral density (L1-L4) was measured by dual-energy X-ray absorptiometry, which was divided into osteoporosis group and non-osteoporosis group.Results:Among the 117 diabetic nephropathy patients, 47 cases were osteoporotic and 70 cases were non-osteoporotic. The proportion of women in osteoporosis group was significantly higher than that in non-osteoporosis group, and BMI, PTH, MHR, ACR and bone mineral density were significantly higher than those in non-osteoporosis group, with statistical significance (all P<0.05). Multivariate binary Logistic regression analysis showed that female, MHR and ACR were independent risk factors for osteoporosis in diabetic nephropathy patients (all P<0.05). Spearman correlation analysis showed that serum MHR and ACR were negatively correlated with lumbar bone density, with statistical significance ( r=0.524 and 0.497, P=0.004 and 0.009, respectively). ROC curve analysis showed that the area under the curve (AUC) of serum MHR and ACR for evaluating osteoporosis in diabetic nephropathy patients was 0.870 (0.809-0.931) and 0.849 (0.792-0.905), respectively. The AUC of serum MHR combined with ACR for osteoporosis in diabetic nephropathy patients was 0.927 (0.891-0.964) . Conclusion:Serum MHR and ACR can be used as the evaluation indexes of osteoporosis in diabetic nephropathy patients, and their combined efficacy is better.

OBJECTIVETo investigate the clinical value of pleural effusion lung ProGRP, neuron specific enolase (NSE), cytokeratin fragment 19 (CYFRA21-1), carcino-embryonic antigen (CEA), carbohydrate antigen 153 (CA153), carbohydrate antigen 19 - 9 (CA19-9) in differential diagnosis and histological typing of malignant pleural effusion caused by lung cancer.

METHODSAll the 171 patients with malignant hydrothorax caused by lung cancer were from coal-mine area of Kailuan. They were divided into the small cell lung cancer (SCLC) group (n = 39), the adenocarcinoma group (n = 99) and the squamous cell carcinoma group (n = 37). The patients with benign pleural effusion served as the controls (n = 30). The diagnostic value of pleural effusion ProGRP, NSE, CYFRA21-1, CEA, CA153 and CA19-9 was compared for each group.

RESULTSYouden index and the accurate rate of pleural effusion ProGRP + NSE (sequence test) were the highest in the diagnosis of malignant hydrothorax caused by SCLC. CEA + CA153 + CA19-9 (sequence test) was the highest in the diagnosis of malignant hydrothorax caused by adenocarcinoma. CYFRA21-1 + CEA + CA153 (on parallel test) were the highest in the diagnosis of malignant hydrothorax caused by squamous cell carcinoma. The Yonden index and the accurate rate were the highest by the single detection of CYFRA21 (0.5514 and 0.6878), and by the combined detection of ProGRP + CYFRA21-1 + CEA (on parallel test) (0.7029 and 0.8878).

CONCLUSIONThe first pleural effusion tumor markers of malignant hydrothorax caused by the SCLC, adenocarcinoma of lung, and lung squamous cell carcinoma are ProGRP, CEA and CYFRA21-1, respectively. The best combinations of pleural effusion tumor marker in diagnosis of malignant hydrothorax caused by the SCLC, adenocarcinoma of lung, lung squamous cell carcinoma and lung cancer are the combined detection of ProGRP + NSE (sequence test), combined detection of CEA + CA153 + CA19-9 (sequence test), the combined detection of CYFRA21-1 + CEA + CA153 (on parallel test) and ProGRP + CYFRA21-1 + CEA (on parallel test), respectively.

OBJECTIVETo set up the fittest medium and optimum condition for plantlets to form microtubers.

METHODPlant hormones, concentration of sucrose, active carbon and light time influenced formation of adventitious root and microtuber in vitro from plantlet of Rehmannia glutinosa (85-5).

RESULT AND CONCLUSIONThe plantlets were cultivated on the medium of microtuber induction after roots were induced on the 1/2MS medium with IBA 1 mg.L-1. The best medium was MS + 6-BA 2 mg.L-1 + NAA 0.1 mg.L-1 + Sucrose 5%. The fittest incubation temperature was 25 degrees C and the light length was (2,000-3,000 lx) 12 h.d-1. Active carbon and GA3 should not be added to the medium, which was not suitable for the induction of microtuber.

OBJECTIVETo set up the optimums for the leaf tissue culture of Chrysanthemum morifolium cultivated in Anhui Province.

METHODLeaves were cut and cultured onto the same kind of media on different sides and defferent kinds of media on the same side, and induced to form the whole plantlet.

RESULT AND CONCLUSIONAll the media used could induce callus, while the results of callus redifferentiation were very distinct. The media with NAA 0.1 mg.L-1 + 6-BA 0.1-1.0 mg.L-1 were much better than others when callus were induced. The MS medium with 6-BA 2.0 mg.L-1 and NAA 0.5 mg.L-1 was the preferable medium for the bud sprouting. The regenerated plantlets produced variation of leaf shape.

To investigate the effects of telmisartan on steatohepatitis (NASH) in rats by activating peroxisome proliferator-activated receptor gamma (r). Thirty male SD rats were randomized into normal control group, NASH control group and telmisartan prevention group. Normal control group was given standard food and the other two groups were given high fat diet for 16 weeks to induce NASH. Prevention group was given telmisartan (5 mg.kg-1.d-1) for 4 weeks by intragastric adminstration after 12 weeks. At the end of the 16th week, all the rats were sacrificed. Pathological changes of liver were observed by optical microscopy. Serum alanine aminotransferase(ALT), aspartate aminotransferase(AST), fasting blood glucose(FBG), fasting insulin(FINS), HOMA-IR(homeostasis model assessment insulin resistance), Serum TNF-a and adiponectin were detected and analyzed.Western blot and RT-PCR were used to detect PPARr expression in hepatic tissues on protein and mRNA levels. (1) Rats were successfully modeled. The liver tissue samples were divided into 4 degrees (F0 - 4) based on total fatty degeneration of liver cells.There was one rat reached F3 and nine rats reached F4 in NASH group, one rat reached F1, six rats reached F2 and three rats reached F3 in prevention group. Inflammatory activity scores of hepatic tissues in the model group were 2.67+/-0.25, while that in the control group was 0 (U=15 and P is less than to 0.01), in the prevention group were 2.67+/-0.25 and 1.36+/-0.12 (U=24 and P is less than to 0.05 ). (2) The levels of serum ALT, AST, FBG, FINS, TNFa and HOMA-IR in the model group were increased than those in the control group( the vaules of q were 13.130, 6.472, 6.909, 26.619, 14.591 and 49.683 respectively, P less than 0.01). The levels of serum ALT, FINS, FBG, TNFa and HOMA-IR in the prevention group were decreased as compared to the model group (the vaules of q were 7.024, 4.145, 14.829, 13.195 and 31.991 respectively, P less than 0.01 ). (3) The serum adiponectin, PPARrmRNA and protein in liver tissues of the model group were lower than those in the control group (q values were 10.696, 8.679 and 16.762 respectively, P is less than to 0.05).The data in the prevention group were higher as compared to the model group(q values were 3.879,3.079,6.400, P is less than to 0.05 respectively). HOMA-IR was positively correlated with the expression of TNFa but negatively correlated with the expression of adiponectin (r = 0.927, P is less than to 0.01; r = -0.891, P is less than to 0.01, respectively). Telmisartan may has preventive effect on rats with steatohepatitis (NASH) by a mechanism of activating peroxisome proliferator-activated receptor r.
