JNK is a key protein in the third stages of MAPK pro-tein kinase activation cascade,and is located in the key node of multiple signal transduction network.It plays a pivotal role in the cell proliferation,differentiation,apoptosis and some other important cell biological processes.Therefore it acts as an im-portant factor in regulating the development of some major human diseases,such as cancer.But the functional diversity and com-plexity of three JNK isoforms in different cell types make it diffi-
cult to develop anticancer drugs with JNK as a treatment target. In this review,we summarized the apoptotic signaling network of JNK and the regulation functions of JNK in cell apoptosis and proliferation.We also discuss the different functions of 3 JNK isoforms in human cancer.

G protein-coupled receptors (GPCRs) are the largest cell surface receptor family, which mediates activities of almost all known cellular response to ligands, including hormones release, neurotransmitters and sensory input.GPCRs can promote development and progression of gastric cancer, colorectal cancer, lung cancer and breast cancer and other tumors.Tyrosine kinase receptors (RTKs) are another important family of membrane receptors, which can regulate cell proliferation, differentiation, migration and survival.Overexpression of RTKs has been found in many cancer cells.Therefore, GPCRs and RTKs are equally important in the clinical treatment of cancer therapeutic.However, GPCRs and RTKs are not independent, and they can use common signal transduction.The present study show that crosstalk between GPCRs and RTKs can facilitate migration of lung epithelial cells, increasing survival of nerve cells and promoting tumor occurrence and development.This article mainly focuses on crosstalk between GPCRs and RTKs and their roles in tumorigenesis and oncotherapy.

This study aimed to identify Inulae Herba, Inulae Flos and their closely related species using the ITS2 bar-code, and secure the quality and clinical curative effect of these medicinal materials. DNA was extracted from Inula linariifolia, I. japonica, I. britanica, which are the original species of Inulae Herba and Inulae Flos, together with their closely related species. The ITS2 sequence was amplified by PCR and sequenced bidirectionally. Sequence assembly and generation of consensus sequence were conducted by the CodonCode Aligner. The genetic distances were comput-ed using MEGA 5.0 in accordance with the Kimura-2-parameter (K2P) model, and the phylogenetic tree constructed by the neighbor-joining (NJ) method. The results showed that the ITS2 sequences of the various species have stable variable sites. The intraspecific genetic distances among Inulae Herba and Inulae Flos were obviously lower than the interspecific genetic distance among the above two medicinal materials and its adulterants. The NJ tree based on ITS2 sequences can clearly differ from Inulae Herba, Inulae Flos and their closely related species. It is concluded that ITS2 sequence can be used as DNA barcode to identify Inulae Herba, Inulae Flos and their closely related species.

OBJECTIVETo evaluate the changes in the renal function of patients with chronic hepatitis B (CHB) receiving adefovir dipivoxil (ADV) or telbivudine (L-DT) monotherapy.
METHODSThis retrospective analysis involved 101 patients with CHB and liver cirrhosis receiving either ADV or L-DT monotherapy for 52 weeks. Serum creatinine, estimates of glomerular filtration rate (eGFR), and the percentage of patients with eGFR≥90 ml·min(-1)·1.73 m(-2) at week 52 were compared with the baseline data between the two groups.
RESULTSThe mean changes of CR at week 52 from baseline were +0.05 mg/dl in ADV group and -0.12 mg/dl in L-DT group, showing a significant difference between the two groups (P=0.000). No patient was found to have an elevation of creatinine over 0.50 mg/dl. The median change of eGFR at week 52 from baseline differed significantly between ADV and L-DT groups (-4.09 vs+18.32 ml·min(-1)·1.73 m(-2), P=0.000). Ninety-two percent (12/13) of the patients with baseline eGFR<90 ml·min(-1)·1.73 m(-2) shifted to eGFR ≥90 ml·min(-1)·1.73 m(-2) after 52 weeks of L-DT treatment, as compared to 38% (3/8) in ADV group. The proportion of patients with eGFR≥90 ml·min(-1)·1.73 m(-2) in L-DT group increased from 76.36% (42/55) at baseline to 94.55% (52/55) at week 52, while that in ADV group decreased from 82.61% (38/46) at baseline to 78.26% (36/46). The constituent ratios of eGFR at different levels were similar at baseline (P=0.443) but significantly different at week 52 between the two groups (P=0.015).
CONCLUSIONL-DT treatment is associated with a renoprotective effect in patients with CHB, but the mechanism remains unclear.

Atherosclerosis (As) is an important pathological basis of cardiovascular and cerebrovascular diseases. The pathogenesis studies of As have been a hot topic in the field of vascular biology research. The inflammation is known as a major participant in the development process of As. And monocyte-macrophage plays a central role in inflam-mation. In recent years, with the deepening research on inflammatory mechanisms, the As macrophage polarization is attracting researchers' attention. Under different environmental inductions, macrophages develop into M1 and M2 phenotypes. M1 macrophages (classical type), which can stimulate the secretion of pro-inflammatory cytokines, is generally considered as pro-inflammatory subtypes and can facilitate the progress of As. Whereas, M2 macrophages (alternative type), which can inhibit pro-inflammatory factor production, function as anti-inflammatory subtypes and likely to inhibit the progression of As. The mechanisms of As, macrophage polarization in As, and opportunities for herbal medicines will be summarized in this review.

OBJECTIVETo evaluate the consistency between the clinical diagnostic criteria and the ascertained diagnostic criteria for diabetic peripheral neuropathy (DPN) in the Preventive and Treatment Guidelines of Diabetes in China (2013) and explore an economic, convenient, and accurate approach to DPN diagnosis.
METHODSThe patients with type 2 diabetes admitted in our department from April to June, 2014 were examined for nerve conduction velocity, 10 g nylon silk, vibration threshold value, sense of temperature and pain, and ankle reflex. The sensitivity, specificity, positive predictive value, negative predictive value, Youden index, and Kappa value were calculated to assess the diagnostic power of the two diagnostic criteria.
RESULTSOf the 151 patients enrolled, 106 (70.2%) had a diagnosis of DPN consistent with the ascertained diagnostic criteria, as compared to 86 (56.95%) who were diagnosed according to the clinical diagnostic criteria; the latter patients accounted for 81.13% of former cases. The sensitivity, specificity, positive predictive value, negative predictive value, Youden index, and Kappa value of the clinical diagnostic criteria were 80.19%, 97.78%, 98.84%, 67.69%, 77.97%, and 0.69, respectively, which were highly consistent with those of the ascertained diagnostic criteria; the sensitivity to compression showed a poor consistency between the two diagnostic criteria. In the 5 screening tests, the combined test of temperature sensation, vibration perception, and ankle reflex showed the highest AUC value among their different combinations.
CONCLUSIONThe clinical diagnostic criteria for DPN show good consistency with the ascertained diagnostic criteria, and for patients with clinical symptoms or with only one positive sign, combination of the two diagnostic criteria can achieve the maximum diagnostic power.
