Purpose To study the expression of HIF-1αand Glut-1 in the molecular subtypes of breast carcinoma and their correlation with basal-like breast carcinoma. Methods 803 cases of invasive breast carcinoma from our database were identified. The clinicopath-ologic findings and the biologic markers including estrogen receptor ( ER) , progesterone receptor ( PR) , and human epidermal growth factor receptor-2 (HER-2) status were reviewed. Immunohistochemical MaxVision stains for cytokeratin 5/6 (CK5/6) and epidermal growth factor receptor ( EGFR) were performed. All breast carcinomas were subclassified into Luminal A, Lumincal B, HER-2 over-expression, normal-like, and basal-like subtypes according to Nielsen criteria. Immunohistochemical stain was also used to detect the expression of HIF-1αand Glut-1. Results Positive expression rates of HIF-1αprotein in basal-like, HER-2 over-expression, normal-like, Luminal A and Luminal B substypes were 77. 89% (74/95), 56. 06% (37/66), 55. 76% (92/165), 31. 97% (141/441), 25. 00% (9/36), respectively. The positive expression rates of Glut-1 protein were 80. 00% (76/95), 57. 58% (38/66), 58. 18%(96/165), 34. 01% (150/441), 25. 00% (9/36), respectively. The positive expression rates of HIF-1α and Glut-1 in the basal-like, HER-2 over-expressing and normal-like subtypes were remarkably higher than that in Luminal A and Luminal B subtypes ( P<0. 004 5) and the expression of HIF-1a and Glut-1 was negatively correlated with the expression of ER (P<0. 01). In the ER-negative breast cancers, the positive expression rates of HIF-1a and Glut-1 in basal-like substype were much higher than that in the other sub-types (P<0. 004 5), and the expression of HIF-1α was positively correlated with expression of Glut-1 in basal-like breast carcinoma (P<0. 01). Conclusion The overexpression of HIF-1αand Glut-1 may be closely related to the ER-negative breast cancer and HIF-1α and Glut-1 might play an important role in the development of basal-like breast carcinoma.

The purpose is to study the prophylactic and therapeutic effect of the traditional Chinese Medicine (TCM)-Jinyebaidu (JYBD) to guinea pig cytomegalovirus (GPCMV) intrauterine infection. The virus-free female and male guinea pigs were screened with nest-polymerase chain reaction (N-PCR). After inbred, pregnant guinea pigs were selected and divided into 3 groups randomly: 5 guniea pigs of the blank control group were not given either GPCMV or JYBD. 31 guniea pigs of the positive control group were inoculated 1 mL (10(7) TCID50) suspension of GPCMV intraperitoneal. 10 guniea pigs of the experimental group were inoculated GPCMV firstly and then perfused stomach with JYBD for 14 days (Dosage in accordance with the modulus of the weight ratio of human to guniea pig). The effects of JYBD on the intrauterine infection of GPCMV were observed. The results showed that JYBD could decrease the maternal infection rate from 100% (31/31) to 50% (5/10) (P < 0.001), the intrauterine infection rate from 100% (72/72) to 75% (21/28) (P < 0.001), and the rate of abnormal outcome of pregnancy from 64.4% (29/45) to 25.0% (7/28) (P < 0.001), the infective symptoms being relieved. It can be concluded that traditional Chinese medicine- JYBD can prevent and treat (GPCMV intrauterine infection, and can be expected a prophylactic drug for HCMV intrauterine infection.

Objective To evaluate the outcome of 1iver transplantation for acute-on-chronic liver failure (ACLF) patients .Methods We included 453 consecutive patients with previously cirrhosis who underwent liver transplantation between January 2013 and December 2017 .Patients were categorized as no ACLF (n=294) and ACLF(n=159) according to EASL-CLIF consortium criteria .Furthermore ,we used ACLF grades to categorize the ACLF patients .Their clinical data were reviewed and their 90-days survival outcomes were compared .Results Compared with the no ACLF group ,the length of stay in the ICU was significantly prolonged for all patients with ACLF ,and the 90-days survival rate after transplantation was significantly reduced in ACLF group .The length of stay in the ICU was shorter in Grade 1 and Grade 2 group when compared to Grade 3 group .The 90-days survival rate of no ACLF ,Grade 1 ,Grade 2 and Grade 3 group were 93 .20％ ,92 .59％ ,93 .33％ and 73 .68％ ,respectively .There were no statistically significant differences in 90-days survival rate among the no ACLF ,Grade 1 and Grade 2 group .However , the 90-days survive rate of Grade 3 group was lower than that of other groups .Conclusions Liver transplantation has been shown to be safe and effective with good outcome in patients with ACLF and should be offered in early course of ACLF before onset of multi-organ failure .

Objective To observe the effect of risperidone on serum brain derived neurotrophic factor ( BDNF) in first-episode schizophrenic patients. Methods In the treatment group, 90 first-episode schizophrenics were treated with risperidone for 16 weeks, and the dose of risperidone was (3.79±0.88) mg·d-1. Serum BDNF levels were measured before treatment, at 2, 8, and 16 weeks after treatment. The severity of schizophrenia symptoms was assessed by the positive and negative symptom scale ( PANSS) before and after sixteen weeks of treatment. Serum BDNF concentrations were measured in 90 healthy controls. Results BDNF in the control group was (22.867±6.051) ng·mL-1. The serum BDNF levels before treatment and at the end of week 2, 8, 16 after the treatment in the treatment group were (14.256±4.096), (13.078±3.462), (18.001±5.753), (21.089± 6.692) ng·mL-1 , and the serum BDNF level was significantly lower in the treatment group than that in the control group ( P<0.01) . After the treatment, the level of BDNF in the treatment group decreased at first and then increased, compared with that before treatment, the difference was significantly ( P<0.05 or P<0.01) . The level of BDNF in the treatment group at the end of week 16 was not significantly different from that of the control group ( P>0.05) . After treatment, the total score of PANSS scale and its subscales decreased, the difference was significantly (P<0.01). At the end of week 16, the PANSS subscale reduction rate was positively correlated to the serum BDNF concentration change (r=0.499, P=0.001). The change rate of serum BDNF concentration at the end of week 16 was not correlated with the dose of risperidone (r=0.103, P=0.335). Conclusion BDNF is abnormal in the first episode of schizophrenia, which can be improved by risperidone treatment.

Objective To investigate the efficacy and safety of programmed cell death protein-1 (PD-1) monoclonal antibody on the treatment of malignant tumor after solid organ transplantation (SOT). Methods The relevant literatures in 7 databases were searched. The data on 54 cases of recipients with malignant tumors treated with PD-1 monoclonal antibody after SOT were collected, and the clinical effects and rejection of SOT recipients treated with PD-1 monoclonal antibody were analyzed. Results Total 32 acceptable articles including 54 SOT recipients were incorporated, including 43 males and 11 females aged 14-79 years old. There are 29 renal transplant recipients, 19 liver transplant recipients and 6 heart transplant recipients. The types of PD-1 monoclonal antibody agent used by SOT recipients included pembrolizumab for 28 patients and nivolumab for 26 patients. The overall remission rate, disease progression rate and fatality rate of PD-1 monoclonal antibody for postoperative malignant tumors of SOT recipients were 32% (17/54), 44% (24/54) and 36% (19/54), respectively. After treatment with PD-1 monoclonal antibody for postoperative malignant tumors of SOT recipients, the incidence of rejection was 39% (21/54), indicating no significant correlation between rejection and type of PD-1 monoclonal antibody (P > 0.05). Conclusions PD-1 monoclonal antibody can effectively treat postoperative malignant tumors of SOT recipients, and may induce rejection during the treatment. But rejection is not the most common cause for death of recipients.

The purpose is to study the prophylactic and therapeutic effect of the traditional Chinese Medicine (TCM)-Jinyebaidu (JYBD) to guinea pig cytomegalovirus (GPCMV) intrauterine infec tion. The virus-free female and male guinea pigs were screened with nest-polymerase chain reaction (N-PCR). After inbred, pregnant guinea pigs were selected and divided into 3 groups randomly: 5guniea pigs of the blank control group were not given either GPCMV or JYBD. 31 guniea pigs of the positive control group were inoculated 1 mL (107 TCID50 ) suspension of GPCMV intraperitoneal. 10 guniea pigs of the experimental group were inoculated GPCMV firstly and then perfused stomach with JYBD for 14 days (Dosage in accordance with the modulus of the weight ratio of human to guniea pig). The effects of JYBD on the intrauterine infection of GPCMV were observed.The results showed that JYBD could decrease the maternal infection rate from 100 % (31/31) to 50% (5/10) (P＜0. 001), the intrauterine infection rate from 100 % (72/72) to 75 % (21/28) (P＜0. 001), and the rate of abnormal outcome of pregnancy from 64.4 % (29/45) to 25.0 % (7/28)(P＜0. 001), the infective symptoms being relieved. It can be concluded that traditional Chinese medicine JYBD can prevent and treat GPCMV intrauterine infection, and can be expected a prophy lactic drug for HCMV intrauterine infection.

Objective To evaluate the effect of donor risk index (DRI) on the early prognosis of liver transplantation for acute-on-chronic liver failure (ACLF). Methods Clinical data of 159 ACLF recipients undergoing liver transplantation were retrospectively analyzed. According to the calculation formula of DRI, all recipients were divided into DRI < 1.65 group (n=96) and DRI≥1.65 group (n=63). Based on the Chronic Liver Failure Consortium acute-on-chronic liver failure score (CLIF-C ACLFs), all recipients were divided into CLIF-C ACLFs < 48 group (n=78) and CLIF-C ACLFs≥48 group (n=81). The early prognosis indexes including the length of intensive care unit (ICU) stay and the length of postoperative hospital stay of the recipients in each group were observed after liver transplantation. The 90 dsurvival rate of the recipients after liver transplantation was analyzed by Kaplan-Meier survival curve. The risk factors affecting the early prognosis of ACLF recipients after liver transplantation were analyzed by Cox's hazards regression model. Results The length of ICU stay and the length of postoperative hospital stay did not significantly differ between the DRI < 1.65 group and DRI≥1.65 group (both P > 0.05). The length of postoperative hospital stay did not significantly differ between the CLIF-C ACLFs < 48 group and CLIF-C ACLFs≥48 group (P > 0.05). The length of ICU stay in the CLIF-C ACLFs < 48 group was 4 (3-14) d, significantly shorter than 7 (1-33) d in the CLIF-C ACLFs≥48 group (P < 0.05). The CLIF-C ACLFs was a risk factor of the early prognosis of ACLF recipients after liver transplantation (P < 0.05). The postoperative 90 d survival rate did not significantly differ between the DRI < 1.65 group and DRI≥1.65 group (P > 0.05). The postoperative 90 d survival rate in the CLIF-C ACLFs < 48 group was 94%, significantly higher than 79% in the CLIF-C ACLFs≥48 group (P < 0.05). Conclusions The early prognosis of ACLF recipients after liver transplantation is correlated with the severity of the disease rather than the DRI. Liver transplantation should be performed early and promptly.
