Objective To investigate the expressions of TRIM59,Twist and E-cadherin in hepatocellular carcinoma and their clinical significance. Methods The expressions of TRIM59,Twist and E-cadherin protein were tested by immunohistochemistry in 80 cases of hepatocellular carcinomas and the adjacent paracancerous tissues. Results The positive rate of TRIM59 in hepatocellular carcinoma was significantly higher than that in the adjacent paracancerous tissue(76.3%vs. 8.0%,P<0.05). Significant difference was also observed in the expres-sion rate of Twist between the hepatocellular carcinomas and the paracancerous tissue(66.3%vs. 6.0%,P<0.05). The positive rate of E-cadherin in hepatocellular carcinoma was significantly lower than that in the adjacent para-cancerous tissue(27.5%vs. 90.0%,P<0.05). The differences of the expression of TRIM59 in hepatocellular carci-noma of pathological grading,tumor differentiation,vascular invasion and clinical TNM stage were significant(P<0.05). The differences of the expression of Twist in hepatocellular carcinoma of pathological grading ,differentia-tion,vascular invasion and clinical TNM stage was also significant(P<0.05,respectively). The differences of the expression of E-cadherin in hepatocellular carcinoma of pathological grading,differentiation,vascular invasion and clinical TNM stage were also significant(P<0.05,respectively). Significantly positive correlation was also found between TRIM59 and Twist by using spearman correlation analysis(P<0.05). Negative correlations were observed between TRIM59 and E-cadherin(P < 0.05),and between Twist and E-cadherin(P < 0.05). Survival analysis showed that TRIM59 expression was an independent prognostic factor in hepatocellular carcinoma. Conclusion TRIM59,Twist and E-cadherin protein expression might be associated with the development,invasion,and metas-tasis of hepatocellular carcinoma. TRIM59 may become a new target gene for the treatment of human hepatocellular carcinoma.

Insulin resistance and insulin secretion deficiency are main machanisms in inducing type 2 diabetes mellitus (T2DM), and mitochondria damage plays an important role in them. Research shows that autophagy is a self-protective mechanism of cells, which plays an important role in maintaining the normal structure and function of pancreatic β cells and improving insulin resistance. Previous studies show that traditional Chinese medicine can regulate cell autophagy to influence β cells and insulin resistance, type 2 diabetes mellitus and its complications. Thus this review will talk about the process of the relationship between autophagy and T2DM and the intervention effect of traditional Chinese medicine.

Objective To evaluate the clinical diagnostic value of pelvic floor sEMG in pelvic floor dyssynergia (PFD) by using receiver operating characteristic curve (ROC curve). Methods The pelvic floor sEMG of 90 patients with PFD and 101normal controls were determined by the Glazer protocol.Parameters including amplitude (AVG),coefficient of variance (CV),onset time and median frequency (MF),and the ROC curve werealso investigated. Results Compared to the control group,the PFD group had a higher AVG of pre-baseline (P < 0.05), a lower AVG during Flick and Tonic steps(P < 0.05), and ahigher CV duringTonic and Endurance steps(P < 0.05).The area under curve(AUC) of CV duringthe tonic step was 0.883 withthe best cut-off of 0.355, and with sensitivity of 88.4%and the specificity of 71.1%, respectively; The AUC of CV duringEndurance step was 0.825 withthe best cut-off of 0.305, and with the sensitivity of 84.9%and the specificity of 67.8% , respectively. Conclusion The CVs of the tonic and the endrnace phases can be used as valuable clinical values in diagnosis of PFD.

AIM:To observe the influence of Lycium barbarum polysaccharide (LBP) on the PI3K/Akt/eNOS signaling pathways in ovariectomized rat myocardium .METHODS:Female SD rats (n=30) were divided into sham oper-ation group , ovariectomized group , progynova group , high-dose LBP group and low-dose LBP group .The serum levels of estradiol, lactate dehydrogenase (LDH) and creatine kinase (CK) were measured by ELISA.The myocardial contents of H2 S and oxidative stress injury-related indicators were also detected .The morphological changes of the myocardium were observed with HE staining.The expression of eNOS and PI3K/Akt pathway-related proteins in the myocardium was deter-mined by Western blot .RESULTS: Compared with sham operation group , the serum level of estradiol , the content of H2 S, the activity of GSH-Px, and the expression of eNOS and PI3K/Akt pathway-related proteins in the myocardium in ovariectomized group were all decreased , and the levels of ROS and MDA in the myocardium were increased (P<0.05). The serum levels of LDH and CK were also increased .The arrangement of the myocardial cells was disordered , and the in-tercellular space was also increased in the ovariectomized group .Compared with ovariectomized group , the serum level of estradiol, the myocardial levels of H2S and GSH-Px, and the protein levels of eNOS and phosphorylated Akt were all in-creased in high dose group, while the levels of ROS and MDA in the myocardium were decreased (P<0.05).The serum levels of LDH and CK were also decreased .The morphological changes of the rat myocardium were improved in high dose group.CONCLUSION: LBP prevents and treats postmenopausal cardiovascular lesions through regulating PI 3K/Akt/eNOS signaling pathways in ovariectomized rats .

Objective To observe the therapeutic effect of catgut-embedding (CE) therapy based on respiration-induced reinforcing and reducing and electro-acupuncture (EA) therapy in treating simple obesity with spleen deficiency and dampness retention. Methods Sixty simlpe obesity patients with spleen deficiency and dampness retention were randomized into CE group and EA group, 30 cases in each group. The acupoints selected for the two groups were the same, and the points were Zhongwan, Shuifen, Qihai, Guanyuan, Tianshu, Liangmen, Daheng, Fujie, Quchi, Xuehai, Yinlingquan, Fenglong, and Ashi. CE group was given CE therapy with the needling for CE therapy referred to the respiration-induced reinforcing and reducing method, and EA group was given EA therapy for 2 continuous treatment courses, 4 weeks constituting one course. Body mass and body mass index (BMI) of the two groups before and after treatment were observed, and the clinical efficacy was also evaluated after treatment. Results (1) After treatment for 2 courses, body mass and BMI of the two groups were obviously decreased(P<0.05 compared with those before treatment), but the differences between the two groups were insignificant (P > 0.05). (2) The total effective rate of CE group was 90.0% and that of EA group was 86.7%, and the difference between the two groups was insignificant (P > 0.05). Conclusion The therapeutic effect of CE therapy based on respiration-induced reinforcing and reducing in treating simple obesity with spleen deficiency and dampness retention is similar to that of EA therapy, and the patients can choose anyone of them for loosing body weight according to the preference.

As a novel transdermal drug delivery technology of minimally invasive, safe and efficient, microneedles have received increasing attention. The microchannels formation by microneedles onto the skin is a prerequisite and key for microneedles to deliver drugs. However, there is still a lack of systematic evaluation in skin microchannels. This review summarized influencing factors and evaluation methods in microchannels formation and healing by microneedles, including geometric parameters, materials for preparation, drugs, penetration parameters, differences among the skin of subjects, and presence or absence of occlusion. This review provides reference for other scholars to further study the effectiveness and security of microneedle applications.
