Objective To study the influence of total bile acid (TBA) of maternal serum and cord blood on neonatal cardiac function in women with intrahepatic cholestasis of pregnancy (ICP). Methods The concentration of TBA in the maternal peripheral blood and neonatal cord blood were measured by enzyme in 30 women with ICP as patients group matched with 30 normogravidas as control group. The concentration of cardiac troponin Ⅰ (cTnI) in cord blood was detected by monoclonal enzymelinked immunosorbent assay.Fetal left ventricle Tei index was evaluated by color Doppler uhrasonoscope. Results (1) TBA concentration of maternal serum and cord blood at ICP group were significantly higher than that of control group [ (36.0±9.6) μmol/L vs. (3.8±0.9) μmol/L, (10.1±2.0) p, mol/L vs. (5.5±0.4 )μmol/L,P <0.01 ]. TBA concentration of maternal serum at ICP group was significantly higher than that of neonatal cord blood(P<0.01 ). Meanwhile, TBA concentration of maternal serum at control group was significantly lower than that of neonatal cord blood (P<0.01 ). (2) The Tel index of neonatal left ventricle at ICP group were significantly higher than that of control (0.58±0.04 vs. 0.43±0.03, P<0.01 ). (3) The concentration of cTnI from cord blood(0.92±0.23)μg/L at ICP group were obviously higher than that of control group [ (0.52±0.10)μg/L, P<0.01]. (4) The TBA concentration of cord blood at ICP group showed positive correlation with maternal blood TBA, cord blood cTnI and fetal left ventricle Tei index respectively( r=0.769, 0.635, 0.758,P<0.01). In the mean time, the positive correlation between the concentration of cTnI from cord blood and fetal left ventricle Tel index was also observed (r=0.637.P<0.01). Conclusions Left ventricular dysfunction and myocardial injury were shown in the neonates with ICP, which might be associated with with the elevated TBA level of maternal blood. The Tel index of fetal left ventricle could be used as a reliable parameter to monitor cardiac function and the degree of injured myocardial muscles.

Objective To investigate the expression and significance of transforming growth factor-?1(TFG-?1) and its correlation with the cellular proliferation activity in human gastric carcinoma (GC). Methods The expression of TGF-?1 and Ki-67 in 50 GC tissues and 10 normal gastric mucosal tissues was examined by immunohistochemistry. Results Compared with the normal gastric mucosal tissues, the expression of TGF-?1 and Ki-67 in GC was significantly higher. TGF-?1 expression was associated with histological differentiation,lymphatic metastasis and invasion depth of GC. And Ki-67 expression was related with lymphatic metastasis and invasion depth of GC too. Furthermore, a significant correlation between TGF-?1 and Ki-67 expressions in GC was found as well. Conclusion Gastric carcinomas with expression of TGF-?1 had high cellular proliferation activity. TGF-?1 could not inhibit cellular proliferation in GC. TGF-?1 stimulated GC cells invasion and metastasis. The overexpression of TGF-?1 and Ki-67 can serve as a reference marker to evaluate GC biological behavior.

Molecular target-based cancer therapy is playing a more and more important role in cancer therapy because of its high specificity, good tolerance and so on. There are different kinds of molecular targeted drugs such as monoclonal antibodies and small molecular kinase inhibitors, and more than 50 drugs have been approved since 1997. When the first monoclonal antibody, rituximab, was on the market. The development of molecular target-based cancer therapeutics has become the main approach. Based on this, we summarized the drugs approved by FDA and introduced their mechanism of actions and clinical applications. In order to incorporate most molecular targeted drugs and describe clearly various characteristics, we divided them into four categories: drugs related to EGFR, drugs related to antiangiogenesis, drugs related to specific antigen and other targeted drugs. The purpose of this review is to provide a current status of this field and discover the main problems in the molecular targeted therapy.

Objective To investigate the correlations between the time of thoracic endovascular aortic repair (TEVAR) and prognosis in patients with type B acute aortic dissection (AADB). Methods The clinical data of 156 AADB patients with TEVAR was retrospectively analyzed and divided into 3 groups according to the time from onset of symptom to TEVAR:less than seven days was deifned as group 1 (G1, n=87), seven days to fourteen days group 2 (G2, n=48);more than fourteen days was group 3 (G3, n=21). The status of aortic reconstruction at three months TEVAR, in-hospital mortalities, mean hospital expense and length of stay were compared among three groups. Results Before TEVAR, there was no signiifcant differences in the ratio of smallest true lumen diameter and largest false lumen diameter amony the three groups (0.47±0.33, 0.42±0.18, 0.47±0.27, respectively, P>0.05). At three months after TEVAR, the ratio of largest true lumen diameter and largest false lumen diameter among the three groups was signiifcantly greater in group 1 (1.76±0.51) than group 2(1.42±0.30) and group 3(1.34±0.34, P < 0.05), when there was no signiifcant difference between the later two groups. Complete aortic reconstruction (8 from group 1 and 4 from group 2) was achieved in 12 patients at 3 months after TAVAR. Eight patients died during hospitalization, 5 from visceral ischemic, 2 from proximal aortic dissection, one patient from sudden death. Compared with G3, the hospital expense of group 1 and group 2 was cut down about ¥20000. Length of stay was signiifcant greater in group 3 than in group 1 and group 2 (P<0.05). Conclusions Early TEVAR for AADB was safe and beneifcial for aortic reconstruct and reducing the hospital expense and length of stay.

Objective To compare the advantages and disadvantages of uniportal video-assisted thoracic surgery(uniportal-VATS)and three portal VATS in treatment of benign pulmonary diseases. Methods The clinical data of 66 patients with benign pulmonary disease treated by VAST from June 2015 to October 2016 were retrospec-tively analyzed. The patients were divided into two groups according to the specific operation. There were 32 patients (18 males and 14 females)in uniportal-VATS group. There were 34 patients(18 males and 16 females)in three portal VATS group. The operative time ,intraoperative blood loss ,thoracic drainage volume at 24 h after opera-tion,incision length,and the time of postoperative drainage of thoracic cavity,postoperative third day pain score and complication rate were compared between the two groups. Results The patients in the experimental and the control groups were successfully operated according to the scheduled protocol. No thoracotomy was performed. There was no statistical difference in the volume of blood loss,the volume of pleural drainage after 24 hours,the time of postoperative drainage of thoracic cavity ,the length of hospital stays and postoperative complications in uni-portal-VATS group and three portal VATS group(P>0.05). The pain score and postoperative third day pain score of the uniportal-VATS group was better than that of the three portal VATS group(P<0.05),but the operation time of the uniportal-VATS group was longer than that of the three portal VATS group(P<0.05). Conclusion Uniportal-VATS is safe and feasible for the treatment of benign lung diseases. It is more minimally invasive and beautiful than traditional three-hole thoracoscopic surgery. It is worthy of promotion and has broad prospects.
