RESUMEN
As one of the main diseases leading to end-stage renal disease, steroid-resistant nephrotic syndrome(SRNS) can cause serious complications such as infection. Without effective control, this disease can further lead to the malignant development of the renal function, bringing serious social and economic burdens. As previously reported, the formation of SRNS is mostly related to the podocyte injury in the body, i.e., the injury of glomerular visceral epithelial cells. Phosphatidylinositol 3-kinase(PI3K)/protein kinase B(Akt) signaling pathway, nuclear transcription factor-κB(NF-κB) signaling pathway, mammalian target of rapamycin(mTOR)/adenosine monophosphate(AMP)-activated protein kinase(AMPK), transforming growth factor(TGF)-β1/Smads, and other signaling pathways are classical signaling pathways related to podocyte injury. By regulating the expression of signaling pathways, podocyte injury can be intervened to improve the adhesion between podocyte foot processes and glomerular basement membrane and promote the function of podocytes, thereby alleviating the clinical symptoms of SRNS. Through the literature review, traditional Chinese medicine(TCM) has unique advantages and an important role in intervening in podocyte injury. In the intervention in podocyte injury, TCM, by virtue of multi-target and multi-pathway role, can regulate and intervene in podocyte injury in many ways, alleviate the clinical symptoms of SRNS, and interfere with the progress of SRNS, reflecting the unique advantages of TCM. On the other hand, TCM can directly or indirectly inhibit podocyte injury by regulating the above signaling pathways, which can not only promote the effect of hormones and immunosuppressants and shorten the course of treatment, but also reduce the toxic and side effects caused by various hormones and immunosuppressants to exert the advantages of small side effects and low price of TCM. This article reviewed TCM in the treatment of SRNS by interfering with podocyte injury-related signaling pathways and is expected to provide a reference for the in-depth study of TCM in the treatment of SRNS, as well as a theoretical basis and a new direction for the clinical application of TCM to shorten the course of treatment of SRNS and delay the progression to end-stage renal disease.

@#Objective To improve the skills of diagnosis and treatment of Trousseau syndrome in order to reduce misdiagnosis and mistreatment.Methods Twelve cases admitted in our hospital and subsequently proved Trousseau syndrome were retrospectively analyzed,including their clinical characteristics,radiography results,and treatment effect.Results Twelve cases began as acute cerebral infarction,associated with increased D-dimer in ten cases and multiple acute infarction involving multiple arterial innervation region in MR of all cases.Among twelve cases,seven cases of lung cancer,one case of pancreatic cancer,two cases of breast cancer and two cases of ovarian cancer were finally diagnosed.Then,six patients were treated with anticoagulant therapy and six abandoned.Conclusion If the lesions’ distribution of acute cerebral infarction doesn’t conform to the conventional and single arterial innervation region in aged patients,doctors should search causes actively,especially should be vigilant about Trousseau syndrome,in order to treat correctly and prevent recurrent episodes that aggravate the disease.
RESUMEN
BACKGROUND@#Many patients with chronic angina experience anginal episodes despite successful recanalization, antianginal and antiischemic medications. Empirical observations suggested that Shenzhu Guanxin Recipe Granules (, SGR), a Chinese herbal compound, exerted potential impacts on increased treadmill exercise performance and angina relieve. However, there has been no systematic study to clarify the impact of SGR on exercise tolerance in patients with stable angina. The SERIES (ShEnzhu guanxin Recipe for Improving Exercise tolerance in patients with Stable angina) trial is designed to determine the effects of SGR on exercise duration, electrocardiographic (ECG) evidence of myocardial ischemia, and incidence of major adverse cardiac events (MACE) in stable anginal patients.@*METHODS@#A total of 184 eligible patients with stable angina will be randomly assigned to receive placebo or SGR (10 g/day for 12 weeks) in a 1:1 ratio. The primary outcome will be the change from baseline in total exercise tolerance duration, time to onset of angina and ECG ischemia during exercise treadmill testing performed over a 12-week study period. The secondary outcome will include ECG measures, the occurrence and composite of MACE and the Seattle Angina Questionnaire score. Moreover, the coronary microcirculation will be evaluated to explore the possible effects in response to treatment of SGR. After the procedure, all participants will be followed up by interview at 3 and 6 months, enquiring about any cardiac events, hospitalizations, cardiac functional level and medication usage. Additionally, the occurrence of adverse events will be evaluated at each follow-up.@*DISCUSSION@#This study may provide novel evidence on the efficacy of SGR in improving exercise tolerance and potentially reducing clinical adverse events.

The relationship between T cell immunoglobulin domain and mucin domain protein 3 (Tim-3)/Galectin (Gal)-9 pathway and recurrent spontaneous abortion (RSA) was studied. Thirty-one pregnant women with RSA and 27 normal early gravidas were investigated to detect the levels of Tim-3 and Gal-9 in villi and deciduas by Western blotting. Meanwhile, the concentration of interleukin (IL)-4 and IL-12 in peripheral blood plasma was determined by ELISA in 25 healthy fertile non-pregnant controls, the normal early gravidas and pregnant women with RSA mentioned above, respectively. It was found that the relative expression levels of Tim-3 and Gal-9 in villi and deciduas were significantly increased in pregnant women with RSA as compared with those in the normal early gravidas. The concentration of IL-4 in peripheral blood plasma of pregnant women with RSA was lower than that of the normal early gravidas (P<0.05) and healthy fertile non-pregnant controls (P<0.05), but that of IL-2 in pregnant women with RSA was significantly higher than that of the normal early gravidas (P<0.05) and healthy fertile non-pregnant controls (P<0.05). It was suggested that the overexpression of Tim-3/Gal-9 pathway may be related to the pathogenesis of RSA.

RESUMEN
This study aimed to identify biochemical predictors of adverse perinatal outcomes in intrahepatic cholestasis of pregnancy (ICP). A total of 106 ICP cases were analyzed retrospectively by the combination of receiver operating characteristic curve and binary logistic regression analysis. "Adverse perinatal outcomes" included spontaneous preterm labor, meconium-staining of amniotic fluid, stillbirth and Apgar score ≤7 at 1 or 5 min. Total bile acid (TBA) [AUC=0.658, 95%CI (0.536, 0.781), P=0.031] was a valuable predictor for adverse perinatal outcomes. The critical value of TBA above which adverse perinatal outcomes were observed was 40.15 μmol/L (Youden's index=0.3). Binary multivariate logistic regression analysis revealed that the risk of adverse perinatal outcomes increased when TBA ≥40.15 μmol/L [OR=3.792, 95%CI (1.226, 11.727), P=0.021]. It is concluded that the risk of adverse perinatal outcomes in ICP increases when maternal TBA ≥40.15 μmol/L.

RESUMEN
OBJECTIVE@#To investigate the diagnostic value of transcranial Doppler ultrasound in early stage cerebral arteriosclerosis.@*METHODS@#We selected 50 patients with early cerebral arteriosclerosis as the disease group. At the same time we selected another 50 patients as a control group with no significant symptoms in the nervous system. By 2 MHz pulse Doppler probe through double-temporal windows and pillow windows Basilar artery (BA), the bilateral middle cerebral artery (MCA) was detected. In the TCD spectrum, we selected the spectrum of a single-family cardiac cycle, identified the starting point (ts), pulse-incisure point (ti), end point (te), and the peak velocity (tp), measured the time of the spectrum starting point to the peak velocity (Tp) and calculated the time required for the peak velocity in the share of ventricular systolic (Tp/Ti), the time required for the peak velocity in the share of the whole cardiac cycle (Tp/T). Tp, Tp/Ti and Tp/T were respectively named as time to peak velocity (TPV), peak-time index-1 (PTI-1) and peak-time index-2 (PTI-2). All data were analyzed by SPSS13.0.@*RESULTS@#There was no significant difference in blood vessel velocity, PI, RI and S/D of BA and RMCA (P>0.05) between the control group and the disease group. Compared with the control group, TPV of the BA, LMCA and RMCA significantly extended, PTI-1 and PTI-2 of BA, LMCA and RMCA increased significantly in the disease group (P0.05).@*CONCLUSION@#TPV, PTI-1 and PTI-2 are sensitive indicators of early stage cerebral arteriosclerosis.
