Abstract
Objective: To investigate the effects of radical radiotherapy combined with different chemotherapy regimens (fluorouracil-based versus docetaxel plus cisplatin) on the incidence of radiation intestinal injury and the prognosis in patients with non-metastatic anal squamous cell carcinoma. Methods: A retrospective cohort study was conducted to recruit non-metastatic anal squamous cell carcinoma patients who underwent chemoradiotherapy in the Sixth Affiliated Hospital of Sun Yat-sen University and Nanfang Hospital from July 2013 to January 2021. Inclusion criteria: (1) newly diagnosed anal and perianal squamous cell carcinoma; (2) completed radical radiotherapy combined with concurrent chemotherapy; (3) tumor could be evaluated before radiotherapy. Exclusion criteria: (1) no imaging evaluation before treatment, or the tumor stage could not be determined; (2) patients undergoing local or radical resection before radiotherapy; (3) distant metastasis occurred before or during treatment; (4) recurrent anal squamous cell carcinoma. A total of 55 patients (48 from the Sixth Affiliated Hospital of Sun Yat-sen University and 7 from Nanfang Hospital) were given fluorouracil (the 5-FU group, n=34) or docetaxel combined with the cisplatin (the TP group, n=21). The evaluation of radiation intestinal injury, hematological toxicity and 3-year disease-free survival (DFS) rate were compared between the two groups. The effects of chemotherapy regimen and other clinicopathological factors on the incidence and severity of acute and chronic radiation intestinal injury were analyzed. The assessment of radiation intestinal injury was based on the American Cancer Radiotherapy Cooperation Group (RTOG) criteria. Results: During radiotherapy and within 3 months after radiotherapy, a total of 45 patients developed acute radiation intestinal injury, including 18 cases of grade 1 (32.7%), 22 cases of grade 2 (40.0%) and 5 cases of grade 3 (9.1%). No patient developed chronic radiation intestinal injury. Among the 34 patients in the 5-FU group, 21 had grade 2-3 radiation intestinal injury (21/34, 61.8%), which was significantly higher than that in the TP group (6/21, 28.6%) (χ(2)=5.723, P=0.017). Multivariate analysis showed that 5-FU chemotherapy regimen was an independent risk factor for radiation intestinal injury (HR=4.038, 95% CI: 1.250-13.045, P=0.020). With a median follow-up period of 26 (5-94) months, the 3-year DFS rate of patients in TP group and 5-FU group was 66.8% and 77.9%, respectively, whose difference was not significant (P=0.478). Univariate analysis showed that the DFS rate was associated with sex, age, tumor location, T stage, N stage, and induction chemotherapy (all P<0.05), while the DFS rate was not associated with chemotherapy regimen or radiation intestinal injury (both P>0.05). Multivariate analysis revealed that age ≥ 50 years old was an independent risk factor affecting the prognosis of patients (HR=8.301, 95% CI: 1.130-60.996, P=0.038). Conclusions: For patients with non-metastatic anal squamous cell carcinoma, radical radiotherapy combined with TP chemotherapy regimen can significantly reduce the incidence of radiation intestinal injury as compared to 5-FU regimen. However, due to the short follow-up time, the effect of different chemotherapy regimens on the prognosis is not yet clear.

Abstract
Objective: To explore the surgical results and clinicopathological features of gastric cancer patients with liver metastases. Methods: The clinicopathological data and post-operative survival of 37 patients who underwent resection of liver metastasis from gastric cancer at our department from Dec. 2007 to Dec. 2014 were analyzed. Results: The 1-, 3-, and 5-year overall survival rates after resection were 91.4%, 57.9%, and 22.0%, respectively, with a median survival of 37 months. Univariate analysis revealed that lymph node metastasis, multiple hepatic metastases and no preoperative chemotherapy are unfavorable prognostic factors for overall survival. Multivariate analysis identified that lymph node metastasis and number of liver metastasis are independent prognostic factors. Conclusions: Gastric cancer patients with a solitary liver metastasis may be good candidates for gastric D2 resection combined with liver R0 resection.

Abstract
We investigated neovasculization effects of embolus-carried human vascular endothelial cell growth factor 165 (VEGF165)-encoded adenovirus (Ad) vector in the hindlimbs of rats with thromboangiitis obliterans (TAO). Rats were equally divided into blank control (I), TAO model (II), embolus (III), Ad-VEGF165 intravascular treatment (IV), Ad-VEGF165 intramuscular treatment (V), and embolus-carried Ad-VEGF165 (VI) groups. After interventional treatment, the neovasculization effect of the test gene was observed using immunohistochemistry. At 1 week after administration, compared with group II, groups V and VI had significantly increased microvessel densities, but no significant difference was observed between groups V and VI. At 2 weeks, groups V and VI exhibited significantly increased microvessel densities. At 1 week after administration, compared with group II, both groups V and VI showed a significant difference in the ratio between the α-smooth muscle actin count and the muscle fiber count, whereas no significant difference was observed between them. At 2 weeks, groups V and VI also exhibited significant differences in these ratios compared with the other groups. We conclude that Ad-VEGF165 promotes neovasculization in ischemic limbs. Embolus-carried Ad- VEGF165 had the most pronounced effect.
