Objective To observe the effect of low molecular weight heparin calcium combined with astraga-lus injection in the treatment of diabetic nephropathy.Methods From January 2013 to December 2014,78 patients with stage III diabetic nephropathy in our hospital were enrolled into the study.They were randomly divided into con-trol group(41 cases) and treatment group(37 cases).The control group received general therapy,such as low protein diets,compound alpha keto acid,insulin,irbesartan,simvastatin.The treatment group was treated with low molecular weight heparin calcium and astragalus injection on the basis of general therapy.The changes of urinary albumin and 24 hours urinary protein after treatment in the two groups were observed.Results After treatment,the negative rate of urinary micro albumin in the treatment group ( 75.68%) was significantly higher than that of the control group (29.27%)(χ2 =16.765,P<0.01).24 hour urinary protein of the treatment group[(176.2 ±82.3)mg/24h]was significantly lower than that of the control group[(223.8 ±87.8)mg/24h](t=2.471,P<0.05).Conclusion Low molecular weight heparin calcium combined with astragalus injection can reduce the proteinuria of diabetic nephropa-thy,it is an effective intervention therapy for early diabetic nephropathy.

Objective To determine the diagnostic value and clinical significance of sonographically detected fetal dysplastic kidney with normal amniotic fluid volume. Methods At the 2nd or 3rd trimester of gestation,the fetuses with unilateral or bilateral renal anomalies (ahnormal size,echo,shape or cyst of the kidney) and normal amniotic fluid volume received systemic ultrasound examination,autopsy or follow-up until after birth. The fetus with only dilated renal pelvis was not included. Results Eleven fetuses of dysplastic renal anomalies with normal amniotic fluid volume were identified by prenatal ultrasound. Among the five fetuses affected by unilateral multicystic kidney dysplasia (MCKD),the renal anomaly was isolated in four fetuses,and the other one was complicated with absence of the ipsilateral hand. One of the two fetuses of unilateral renal agenesis had no other associated anomaly and the other one was complicated with hydrocephalus,spina bifida,ipsilateral absent radius and single umbilical artery,correspongding to the VACTERL syndrome. Two fetuses of pelvic kidney and horseshoe kidney respectively was proved by postnatal ultrasound. One fetus was diagnosed as autosomal dominant polycystic kidney disease(ADPKD)on the basis of multiple renal cysts and a positive family history,the fetus also had cardiac rhabdomyoma. One fetus of bilateral normal sized hyperechoic kidneys was proved to be renal dysplasia by autopsy. Conclusions Unilateral MCKD is the most common type of fetal renal dysplasia which can be detected by prenatal ultrasound with normal amniotic fluid volume. Based on the sonographic characteristics and the family history,most of the dysplastic renal anomalies can be diagnosed prenatally and the prognosis can be predicted.

In this study, ultra performance liquid chromatography-quadrupole-time of flight mass spectrometer-MS^E (UPLC-Q-TOF-MS^E) combined with UNIFI analysis platform was used to rapidly analyze and identify the metabolites of hederagenins 3-O-α-L-rhamnosyl-(1→2)-[β-D-glucopyranosyl-(1→4)]-α-L-arabopyranoside (Pulsatilla saponin D) and oleanolic acid 3-O-α-L-rhamnosyl-(1→2)-[β-D-glucopyranosyl-(1→4)]-α-L-arabopyranoside (Pulsatilla saponin B₇) and hederagenins 3-O-α-L-rhamnosyl-(1→2)-α-L-arabopyranoside (Pulsatilla saponin BD) in plasma and colonic tissue of normal and ulcerative colitis (UC) rats. The database and analysis methods were established based on the precise molecular weight of compounds, retention time, neutral loss and reported data, and then the final data were obtained by comparing with the blank control group, combining with the deviation and the cracking rule of the compound. The results showed that the glucoses, hydroxylation and dehydroxylation, methylation and demethylation, dehydrogenation, decarboxylation and hydrolysis of saponin D, B₇ and BD occurred in the plasma and colon tissues of normal and UC model rats. This study will clarify the metabolic transformation of Pulsatilla saponins D, B₇ and BD in rats, determine the prototype components and their metabolites that enter the body, and whether colon injury will affect their metabolism in vivo, so as to explore the possible anti-colitis effective components in the prototype or metabolites of Pulsatilla saponins D, B₇ and BD. This experiment was approved by Animal Ethics Committee of Jiangxi Science and Technology Normal University (approval number: Y202227).

Objective To explore the effects of C-pseudonucleosides bearing thiazolidin-4-one as immunostimulants on differentiation and activation of human lymphocytes. Methods Peripheral blood mononuclear cells (PBMC) were isolated from healthy adults,and then incubated with immunostimulants (CH1a,CH2a,CH1b,CH2b and pidotimod).After 48 h,we collected the supernatants and then detected the concentrations of IL-2,IL-4 and IFN-γ using ELISA.After 72 h,the proliferation was detected using MTT method.PBMC incubated with immunostimulants (CH1a,CH2a,CH1b,CH2b and pidotimod),after 72 h,the cultural cells were collected and CD expressions of lymphocytes were analyzed by flow cytometry.Results All samples could stimulate proliferation of T cells.Immunostimulants CH1a,CH2a and pidotimod could elevate the expressions of CD3,CD4,CD19 and CD16CD56,and stimulate the secretions of IL-2 and IFN-γ. Immunostimulants CH1b and CH2b could elevate the expressions of CD3,CD4,CD19 and CD16CD56,and stimulate the secretions of IL-2 and IL-4. Conclusion Immunostimulants CH1a and CH2a could differentiate Th0 into Th1 and promote the proliferation of B cells as well as NK cells.However,immunostimulants CH1b and CH2b could differentiate Th0 into Th2 and promote the proliferation of B cells and NK cells.

Objective To assess the prevalence and risk of coronary artery disease (CAD) in Chinese adults with type 2 diabetes mellitus (T2DM) using electron beam computed tomography (EBCT) and EBCT angiography (EBCTA). Methods: Ninety-four cases were enrolled in this study including diabetes (n=28), impaired glucose tolerance (IGT, n=30), coronary heart disease (CHD, n=11), and control (n=25). Cardiac EBCT plain scanning and EBCTA were performed on all of these subjects to evaluate coronary artery calcification (CAC) scores, and number of segments of stenosed coronary arteries. Both CAC and/or coronary artery stenosis were defined as patients with coronary artery lesions (CAL). Results CAC scores were not different with the control, diabetes, IGT, or CHD (P＞0.05)groups. Compared to control (0.520±1.295), more stenosed coronary arteries segments (P＜0.05) were detected in diabetes (2.964±1.915), IGT (2.200±2.024), and CHD (2.273±1.679). Number of stenosed artery segments were correlated with age (r=0.215, P=0.019),postprandial glucose (r=0.224, P=0.015), total cholesterol (r=0.323, P=0.000), and duration of diabetes (r=0.208, P=0.004). The incidences of CAL in diabetes (96.43%), IGT (93.33%), and CHD (90.91%) was substantially higher than that in normal control (56.00%, P＜0.01).The odds ratio of CAL associated with having diabetes was estimated to be 7.514 (95% CI: 1.885-63.778). Conclusions Coronary artery lesions are prevalent in Chinese adults with type 2 diabetes, implying a high CAD risk. EBCTA holds potential in depicting the details of CAL and can be used to track the progression of CAD in diabetes patients.
