OBJECTIVE: To explore the diagnosis and reasonable surgical approach for parapharyngeal space neoplasms. METHOD: From July 2004 to July 2009, a retrospective review of 45 patients with neoplasms of parapharyngeal space was performed. Fourty-five cases were examined by CT, some of them were examined by MRI or DSA. Several surgical approaches were selected. The transcervical approach was used in 35 cases, the transparotid approach was used in 5 cases, the transmandible approach was used in 2 cases, and the transparotid and temporal approach was used in 3 cases. RESULT: Among 45 patients, 37 cases (82.22%) were benign and 8 cases (17.78%) were malignant. Neurogenic neoplasms and salivary glands neoplasms were the most common tumors. Using CT, MRI or DSA could obtain useful information about the location, size, shape, density and degree of enhancement of the parapharyngeal space neoplasms, acquire their relationship with styloid and carotid, and make preoperative diagnosis. The diagnostic coincidence rate between preoperative diagnosis and pathological diagnosis was 80% (origin of tissue). All benign tumors were completely resected. A lymphangiomas had recurrence after 1 year,and the second operation had no recurrence. In the 45 cases, 8 cases were malignant tumors. Of 2 patients with malignant mixed tumors, 1 survived disease free after a follow-up of 4 years,and another was still alive with disease after a follow-up of 3 years; Of 2 patients with synovial sarcomas, 1 survived disease free for a follow-up of 3 years, the other one survived disease free after a follow-up of 2 years; 1 patient of nasopharyngeal carcinoma with metastasis in the parapharyngeal space had post-operative radical radiotherapy and survived disease free after a follow-up of 5 years. One patient with chordoma was still alive with disease after a follow-up of 3 years; 1 patient with poorly differentiated squamous cell carcinoma, died of pulmonary metastasis after a 4 year follow-up; 1 case with follicular dendritic cell sarcoma survived disease free after a follow-up of 2 years. CONCLUSION CT, MRI and DSA are essential for the diagnosis and differentiation of parapharyngeal space neoplasm. The transcervical approach is a simple, safe and minimal invasive procedure for resecting parapharyngeal space neoplasms. It is the best approach for treatment of parapharyngeal space neoplasms.

OBJECTIVE: To study siRNA inhibited the expression of mRNA and protein of NF-kappaBp65 in the Hep -2 cell line. METHOD: Hep-2 were transfected with p65SiRNA. Western blotting was used to examine the protein levels of NF-kappaBp65. RT-PCR method was adopted to determine the mRNA expression of NF-kappaBp65. MTT method was adopted to investigate the proliferation of the Hep-2 cells after the transfection of p65siRNA. RESULT: The western blotting result showed that the level of NF-kappaBp65 protein was gradually declined after transfection of p65siRNA. The RT-PCR result showed that transfection with p65siRNA caused special degradation of the p65mRNA in Hep-2 cells at 24, 48 and 72 h. After transfection with p65siRNA. CONCLUSION p65siRNA has significant inhibition effects on the proliferation of the Hep-2 cells and expression of purpose gene mRNA and protein. The inhibition effects are time depended.

Objective: To investigate the clinical value of lymph node dissection (LND) in the radical resection of intrahepatic cholangiocarcinoma (ICC). Methods: The propensity score matching and retrospective cohort study was conducted. The clinicopathological data of 448 patients with ICC who were admitted to 12 medical centers from December 2011 to December 2017 were collected, including 279 in the Eastern Hepatobiliary Surgery Hospital of Navy Medical University, 32 in the Mengchao Hepatobiliary Hospital of Fujian Medical University, 21 in the First Hospital Affiliated to Army Medical University, 20 in the Cancer Hospital Chinese Academy of Medical Science and Peking Union Medical College, 19 in the West China Hospital of Sichuan University, 18 in the Second Hospital Affiliated to Zhejiang University School of Medicine, 18 in the Renji Hospital Affiliated to Shanghai Jiaotong University School of Medicine, 16 in the Beijing Friendship Hospital Affiliated to Capital Medical University, 10 in the Xuanwu Hospital Affiliated to Capital Medical University, 7 in the Tongji Hospital Affiliated to Tongji Medical College of Huazhong University of Science and Technology, 5 in the Beijing Tiantan Hospital Affiliated to Capital Medical University, and 3 in the Affiliated Hospital of North Sichuan Medical College. There were 281 males and 167 females, aged from 22 to 80 years, with a median age of 57 years. Of the 448 patients, 143 with routinely intraoperative LND were divided into LND group and 305 without routinely intraoperative LND were divided into control group, respectively. Observation indicators: (1) the propensity score matching conditions and comparison of general data between the two groups after matching; (2) intraoperative and postoperative situations; (3) follow-up; (4) survival analysis. Patients were followed up by outpatient examination, telephone interview and email to detect survival of patients and tumor recurrence up to October 31, 2018 or death. Follow-up was conducted once every 3 months within postoperative 1-2 years, once every 6 months within postoperative 2-5 years, and once a year after 5 years. The propensity score matching was realized using the nearest neighbor method with 1∶1 ratio. Measurement data with normal distribution were represented as Mean±SD, and comparison between groups was analyzed using the t test. Measurement data with skewed distribution were represented as M (range), and comparison between groups was analyzed using the Mann-Whitney U test. Count data were described as absolute numbers, and comparison between groups was analyzed using the chi-square test or Fisher exact probability. Kaplan-Meier method was used to calculate survival rates and draw survival curve, and Log-rank test was used to perform survival analysis. Univariate analysis and multivaraiate analysis were conducted using the Log-rank test and COX regression model, respectively. Results: (1) The propensity score matching conditions and comparison of general data between the two groups after matching: 286 of 448 patients had successful matching, including 143 in each group. The number of males and females, cases with hepatitis, cases with grade A and B of Child-Pugh classification, cases with distance from margin to tumor <1 cm and ≥1 cm, cases with highly, moderately, and poorly differentiated tumor, cases with anatomical hepatectomy and nonanatomical hepatectomy before propensity score matching were 77, 66, 33, 96, 47, 70, 73, 105, 38, 79, 64 in the LND group, and 204, 101, 121, 165, 140, 207, 98, 251, 54, 124, 181 in the control group, respectively, showing significant differences in the above indices between the two groups (χ²=7.079, 11.885, 7.098, 14.763, 5.184, 8.362, P<0.05). After propensity score matching, the above indices were 77, 66, 33, 96, 47, 70, 73, 105, 38, 79, 64 in the LND group, and 79, 64, 29, 88, 55, 71, 72, 112, 31, 74, 69 in the control group, respectively, showing no significant difference in the above indices between the two groups (χ²=0.056, 0.329, 2.158, 0.014, 0.936, 1.400, P>0.05). (2) Intraoperative and postoperative situations: the operation time, volume of intraoperative blood loss, cases with intraoperative blood transfusion, cases with postoperative complications, and duration of postoperative hospital stay were 265 minutes (range, 160-371 minutes), 300 mL (range, 200-500 mL), 37, 46, 12 days (range, 9-17 days) for the LND group, and 59 minutes (range, 46-250 minutes), 200 mL (range, 100-400 mL), 24, 25, 9 days (range, 7-11 days) for the control group, respectively. There was no significant difference in the volume of intraoperative blood loss or cases with intraoperative blood transfusion between the two groups (Z=1.700, χ²=3.520, P>0.05). There were significant differences in the operation time, cases with postoperative complications, and duration of postoperative hospital stay (Z=6.520, χ²=8.260, Z=4.270, P<0.05). (3) Follow-up: 143 patients in the LND group was followed up for 18-26 months. The 1-, 3-, 5-year survival rates were 66.9%, 32.8%, 25.0%, and the median survival time was 22.0 months (range, 18.0-26.0 months). In the control group, 143 patients were followed up for 11-32 months. The 1-, 3-, 5-year survival rates were 71.7%, 38.0%, 31.0%, and the median survival time was 22.0 months (range, 11.0-32.0 months). There was no significant difference in the overall survival between the two groups (χ²=0.466, P>0.05). (4) Survival analysis: results of univariate analysis showed that distance from margin to tumor, tumor diameter, the number of tumors, microvascular tumor thrombus, and lymph node metastasis by pathological examination were related factors for prognosis of patients undergoing radical resection of ICC (χ²=10.662, 9.477, 16.944, 6.520, 11.633, P<0.05). Results of multivariate analysis showed that distance from margin to tumor<1 cm, tumor diameter>5 cm, multiple tumors, microvascular tumor thrombus, positive lymph node metastasis by pathological examination were independent risk factors for prognosis of patients undergoing radical resection of ICC (hazard ratio=0.600, 1.571, 1.601, 1.750, 1.723, 95% confidence interval: 0.430-0.837, 1.106-2.232, 1.115-2.299, 1.083-2.829, 1.207-2.460, P<0.05). Conclusion Lymph node metastasis is an independent risk factor affecting the prognosis of ICC patients, and it is necessary to perform LND in radical resection for patients with ICC and lymph node metastasis.
