Objective To investigate the value of magnetic resonance diffusion weighted imaging (DWI) and apparent diffusion coefficient (ADC) in detection of central gland prostate cancer (CGPCa).Methods Routine MRI and DWI examination were performed in 25 CGPCa patients and 30 benign prostate heperplasia (BPH) patients.Then the ADC value was measured according to the image of the lesion after DWI,and the receiver op erating characteristic (ROC) curve was analyzed to select the best ADC value for diagnosis of CGPCa.Results The ADC value of CGPCa (0.89±0.12×10-3 mm2/s) was smaller than that of BHP (1.43±0.12x10-3 mm2/s),and the dif ference was statistically significant (P＜0.05).When the cut off point of ADC value was set at 1.192×10-3 mm2/s,the sensitivity was 80.0％ and the specificity was 85.0％.Conclusion DWI and ADC have clinical application value in diagnosis of CGPCa.

Objective:To study the diagnostic value of MR diffusion weighted imaging (DWI) and CT and MR perfusion imaging in patients with different degrees of liver cirrhosis.Methods:A total of 60 patients with liver cirrhosis,who were treated in Ziyang Hospital of West China Hospital of Sichuan University from August 2015 to February 2017 were selected.According to the Child-Pugh classification,32 cases of grade A were mild cirrhosis (denoted as group A),16 cases of grade B and 12 cases of grade C were moderate to severe cirrhosis (denoted as group B),30 healthy volunteers were selected as group C in the same period.All the subjects in the three groups were examined by DWI,CT and MR perfusion imaging.The ADC value,hepatic portal perfusion ratio [SSr (CT) and SSr (MR)] were compared among the three groups,and Spearman correlation analysis was used to analyze the correlation between the indexes.Results:There was no significant difference in ADC values among the three groups (P＞0.05),and the ADC values of group A and B were lower than those of group C,but the difference was not statistically significant (P＞0.05).There was no significant difference in ADC values between group A and B (P＞0.05).The levels of SSr (CT) and SSr (MR) in the three groups were compared,the difference was statistically significant (P＜0.05);the levels of SSr (CT) and SSr (MR) in group B were significantly higher than those in group A and C,the difference was statistically significant (P＜0.05).There was no significant difference in the levels of SSr (CT) and SSr (MR) in group A and C (P＞0.05).Spearman correlation analysis showed that SSr (CT) was positively correlated with SSr (MR) in the patients with liver cirrhosis (r=0.687,P=0.000).Conclusion:CT and MR perfusion imaging can reflect the lesion degree of liver cirrhosis,and diagnostic effects of the two are better than DWI imaging,which is worthy of clinical promotion.

Objective:To investigate the application value of digital X-ray radiotherapy and single photon emission computed tomography(SPECT)radionuclide bone imaging in the diagnosis of intertrochanteric fracture of femur.Methods:A total of 70 patients who were diagnosed as intertrochanteric fracture of femur in Shijiazhuang People's hospital from January 2017 to December 2020 were selected,and they were divided into study group and control group according to random number method,with 35 cases in each group.Digital X-ray radiography combined with SPECT radionuclide bone imaging was used in the study group,and digital X-ray radiography was used in the control group.And then,the accuracy of the diagnostic results between the two groups were compared.Results:The radiographic examination indicated that 31 cases(88.6%)of 35 cases in the study group were confirmed,and 24 cases(68.6%)of 35 cases in the control group were confirmed.The diagnostic accuracy rate of the study group was significantly higher than that of the control group,and the difference was statistically significant(x2=4.158,P<0.05).The preoperative imaging diagnosis indicated that diagnosed number of fracture blocks in the study group was(3.57±0.50),which was significantly higher than that(2.67±0.40)in the control group,and the difference of that between two groups was statistically significant(t=8.315,P<0.05).In the actual intraoperative examining for bone continuity,5 cases were continuity and 30 cases were non-continuity.In the bone stability,13 cases were stability and 22 cases were non-stability.The study group was closer to intraoperative bone continuity and bone stability,and the differences of them between two groups were statistically significant(x2=12.857,4.644,P<0.05),respectively.Conclusion:The combination of digital X-ray radiography and SPECT radionuclide bone imaging has higher diagnostic value for intertrochanteric fracture of femur,which can provide important reference for clinical diagnosis.

Background: and Purpose Non-high-density lipoprotein cholesterol (non-HDL-C), which represents the total cholesterol content of all pro-atherogenic lipoproteins, has recently been included as a new target for lipid-lowering therapy in high-risk atherosclerotic patients in multiple guidelines. Herein, we aimed to explore the relationship between non-HDL-C level and the efficacy and safety of ticagrelor-aspirin versus clopidogrel-aspirin in preventing stroke recurrence. Methods: This study comprised a post hoc analysis of the CHANCE-2 (Ticagrelor or Clopidogrel in High-Risk Patients with Acute Nondisabling Cerebrovascular Events II) trial, from which 5,901 patients with complete data on non-HDL-C were included and categorized by median non-HDL-C levels, using a cutoff of 3.5 mmol/L. The primary efficacy and safety outcomes were recurrent stroke and severe or moderate bleeding within 90 days. Results: Ticagrelor-aspirin significantly reduced the risk of recurrent stroke in patients with low non-HDL-C (71 [4.8%] vs. 119 [7.7%]; adjusted hazard ratio [HR] 0.54; 95% confidence interval [CI], 0.40–0.74), but not in those with high non-HDL-C (107 [7.3%] vs. 108 [7.6%]; adjusted HR, 0.88; 95% CI, 0.67–1.16), compared with clopidogrel-aspirin (P for interaction=0.010). When analyzed as a continuous variable, the benefit of ticagrelor-aspirin for recurrent stroke decreased as non-HDL-C levels increased. No significant differences in the treatment assignments across the non-HDL-C groups were observed in terms of the rate of severe or moderate bleeding (5 [0.3%] vs. 8 [0.5%] in the low non-HDL-C group; 4 [0.3%] vs. 2 [0.1%] in the high non-HDL-C group; P for interaction=0.425). Conclusion CHANCE-2 participants with low non-HDL-C levels received more clinical benefit from ticagrelor-aspirin versus clopidogrel-aspirin compared to those with high non-HDL-C, following minor ischemic stroke or transient ischemic attack.

Objective: This study aims to explore the clinical value of fusion indocyanine green fluorescence imaging (FIGFI) in total laparoscopic radical resection for right colon cancer. Methods: From October, 2018 to December, 2018, 15 patients who underwent total laparoscopic radical resection for right colon cancer using FIGFI in Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College were retrospectively enrolled in this study. Data regarding surgical outcomes, postoperative recovery, pathological outcomes and complications were collected and analyzed. Results: All patients successfully underwent total laparoscopic radical resection for right colon cancer using FIGFI. 1 patients (6.7%) received extended resection of bowel due to poor blood supply after mesentery excision. The average operation time was 133.7 minutes and intraoperative blood loss was 26.7 ml. The average time to ground activities, fluid diet intake, first flatus and postoperative hospitalization were 19.1 h, 11.7 h, 32.5 h and 5.0 d, respectively. The average length of tumor was 4.5 cm. The average proximal and distal resection margins were 14.9 cm and 12.1 cm, respectively. The average number of lymph nodes retrieved was 29.3 per patient. Only one patient suffered from incisional fat liquefaction after surgery and was managed effectively by regular dressing change. No severe complications such as indocyanine green allergy, anastomotic stenosis, anastomotic leakage, abdominal bleeding, bowel obstruction, pulmonary infection, and abdominal infection occurred in any patients. Conclusions FIGFI is helpful to judge the blood supply of intestinal segments and anastomotic stoma in total laparoscopic radical resection for right colon cancer quickly. It is a safe and feasible technique with satisfactory short-term effect.

Objective: The aim of this study was to explore the clinical safety, feasibility and short-term effect of overlapped delta-shaped anastomosis in total laparoscopic transverse colectomy. Methods: The records, which were based on China National Cancer Center, of 20 and 31 patients who underwent total laparoscopic transverse colectomy with overlapped delta-shaped anastomosis and laparoscopic-assisted transverse colectomy with conventional extracorporeal anastomosis, from March 2017 to May 2018 were reviewed retrospectively. Data regarding surgical outcomes, postoperative recovery, pathological outcomes and perioperative complications were collected and compared. Results: There was no difference between the two groups in overall operation time, anastomosis time and intraoperative blood loss (P>0.05), however, the length of incision was significantly shorter in overlapped delta-shaped group [(4.7±0.6) cm vs. (5.5±1.0) cm, P=0.002]. The time to ground activities, first flatus and postoperative hospitalization did not differ between the two groups (P>0.05). The postoperative visual analogue scale was lower in the overlapped delta-shaped group than the control group on postoperative day 1 (3.7±0.7 vs. 4.2±0.9, P=0.015) and postoperative day 3 (2.7±0.5 vs. 3.2±0.9, P=0.040). The perioperative complication rates were 10.0% and 12.9% in the overlapped delta-shaped group and the control group, respectively, and the difference was not significant (P=0.753). Conclusion Compared to conventional extracorporeal anastomosis, total laparoscopic transverse colectomy with overlapped delta-shaped anastomosis was a safe and feasible procedure with satisfactory short-term effect, shorter incision and less postoperative pain.

Cetuximab has become an important molecular targeted drug for the treatment of metastatic colorectal cancer (mCRC), which increases the curative effect of chemotherapy and prolongs the survival time. However, some patients develop insensitiveness or resistance to cetuximab, while the complicated molecular mechanisms are not quite clear. With the deep research in epidermal growth factor receptor (EGFR) signaling pathway, the genetic alteration of KRAS, BRAF, PTEN and PIK3CA and polymorphism of microRNA (miRNA) have been proved to associated with cetuximab resistance. Wnt signaling pathway with its negative regulator RNF43 is also considered to be related with cetuximab resistance in recent studies. The review of the progress on molecular mechanisms of cetuximab resistance in mCRC can establish theoretical basis for finding out reasonable drugs to overcome the resistance.

Objective: To explore the clinical safety and feasibility of enterostomy using running suture of dermis and seromuscular layer in laparoscopic-assisted radical resection for rectal carcinoma. Methods: From May 1, 2017 to May 1, 2018, 46 patients who underwent laparoscopic-assisted radical resection for rectal carcinoma with enterostomy using running suture of dermis and seromuscular layer in Cancer Hospital, Chinese Academy of Medical Sciences were retrospectively enrolled in this study. Data regarding clinicopathologic characteristics, operation and postoperative outcomes, stoma-related complications and functions of stoma were collected and analyzed. Results: All of the 46 patients successfully underwent this operation. Among them, 30 patients underwent laparoscopic-assisted abdominoperineal resection for rectal cancer with sigmoidostomy and 16 patients underwent laparoscopic-assisted low anterior resection for rectal cancer with loop ileostomy. The mean operation time was 115.3 minutes and intraoperative blood loss was 86.1 ml. The mean time for enterostomy was 14.1 minutes. The average time to flatus, time to fluid diet intake and length of hospital stay were 1.8 days, 2.9 days and 6.5 days, respectively. During the follow-up period, three patients suffered from stomal edema, two patients suffered from parastomal hernia, and two patients suffered from skin inflammation surrounding stoma. None of re-operation related stoma and severe mobility such as stomal stenosis, stomal necrosis, stomal prolapse, stomal retraction and stomal mucocutaneous separation occurred. Thirty-five patients recovered with satisfactory stomal function, two with middle function and one with poor function. Conclusion Enterostomy using running suture of dermis and seromuscular layer in laparoscopic-assisted radical resection for rectal carcinoma is a safe and feasible procedure with a satisfactory short-term effect.
