Objective To observe the effect of residual tumor after radiotherapy on survival rate of patients with nasopharyngeal carcinoma (NPC). Methods From Jan. 1989 to Dec. 1998, 108 of 304 NPC patients pathologically confirmed, had residual tumor after radical radiotherapy, of whom, 26, 68, 14 had residual lesion in the nasopharyngeal cavity alone, cervical lymph node alone, and nasopharyngeal cavity plus cervical lymph node. Results The overall 1 , 3 , 5 , and 10 year survival rates (OS) significantly decreased in the residual group. The highest OS was in the group with nasopharynx residual alone, and the lowest in nasopharynx plus residual lymph node group. The bigger the residual lesion, the lower the OS. Conclusions The overall survival rate decreases in patients with residual lesion after radiotherapy, especially in patients with both nasophrynx and regional lymph node residual. Tumor residual after radiotherapy can be a prognostic indicator for patients with NPC.

ObjectiveTo investigate the effect of jin’s three-needle scalp electroacupuncture on Cyt-c and Caspase-3 expressions in the cerebral cortex in Intrauterine distress-induced HIBD rats and reveal the mechanism of its protective action on the brain. MethodThe abdomen was incised in a female SD rat at 21 days of pregnancy. Bilateral uterine horn blood vessels were tightly clamped with a hemostat for five minutes. An infant rat was then taken out by a cesarean section. A rat model of hypoxic-ischemic brain damage was confirmed by the use of a behavior test and braintissue sections. The rats were randomized into model and acupuncture groups. The model group was not needled. Acupuncture groups 1, 2, 3 and 4 began to be needled at 3, 5, 7 and 14 days after birth, respectively. Acupuncture treatment was given for seven consecutive days. The normal control group was naturally delivered, not used to make a model and not needled. All groups of rats were decapitated to take the brain tissue at 21 daysafter birth. Cyt-c and Caspase-3 expressions in the cerebral cortex were detected.ResultCyt-c optical density value decreased somewhat in the four acupuncture groups; there was a statistically significant difference between acupuncture group 1 or 2 and the modelgroup (P<0.05). Caspase-3 expression was significantly down-regulated in acupuncture group 1; there was a statistically significant difference compared with the model group (P<0.05).ConclusionThe protective effect of acupuncture beginning at 3 days after birthon the brain is related to the down-regulation of Cyt-c and Caspase-3 expressions in intrauterine distress-induced HIBD rats.

Objective To compare the efficacy and safety of two concurrent chemoradiotherapy regimens between paclitaxel plus fluorouracil( TF) and cisplatin plus fluorouracil ( PF) in the treatment of locally advanced esophageal squamous carcinoma. Methods 103 patients with locally advanced esophagus carcinoma were treated in Affiliated Hospital of Jiangnan University from December 2014 to February 2016, and randomly assigned to either study group ( TF ) or control group ( PF ) according to random number table, of which 52 patients in the TF group while 51 patients in the PF group. The primary outcome was overall survival(OS), and secondary outcomes include progression-free survival(PFS), local progression-free survival( LPFS) and side effects. Results The 1-year OS for TF group was 76. 9% versus 74. 5% for PF group( P>0. 05 ) , and the 2-year OS for TF group was 59. 6% versus 56. 9% for PF group ( P >0. 05). The 1-year LPFS for TF group and PF group were 71. 2% and 66. 7% respectively(P>0. 05), and the 2-year LPFS for TF group and PF group were 61. 5% and 58. 8% respectively(P>0. 05). The 1-year PFS for TF group was 63. 5% versus 62. 7% for PF group ( P>0. 05 ) , and the 2-year PFS for TF group was 51. 9% versus 39. 2% for PF group ( P>0. 05 ) . The incidence rate of serious ( grade 3- 4 ) leukopenia for TF group was 36. 5% versus 17. 6% for PF group(χ2 =4. 642, P<0. 05). The incidence rate of serious (grade 3-4) acute radiation pneumonitis was 15. 4% in the TF group, higher than that in the PF group with the rate of 3. 9%(χ2 =3. 859, P<0. 05), while the incidence rate of severe nausea and vomiting for PF group was 17. 6% versus 1. 9% for TF group(χ2 =7. 262, P <0. 05). The difference between the two groups was statistically significant. Conclusions Patients who were treated with two concurrent chemoradiotherapy regimens showed no difference in OS, PFS and LPFS. The regimen on the basis of Paclitaxel has higher risk of adverse effects incidence rates of hematological toxicity and acute radiation pneumonitis, while digestive system toxicity must be concerned when concurrent chemoradiotherapy is performed on the basis of cisplatin plus fluorouracil.

Objective:To analyze the correlation between the Naples prognostic score (NPS) after preoperative neoadjuvant chemoradiotherapy in locally advanced rectal cancer (LARC) and evaluate the prognostic value of NPS in LARC.Methods:136 patients with LARC meeting the recruitment criteria from 2015 to 2020 were selected. Serum albumin, total cholesterol (TC) were collected and neutrophil-lymphocyte ratio and lymphocyte-monocyte ratio were calculated. All patients were scored and graded according to the NPS rule. The survival rate was calculated with Kaplan- Meier method. Multivariate prognostic analysis was performed by Cox models. Results:There was no significant correlation between NPS score and tumor regression or pathological complete response (pCR) of LARC patients after neoadjuvant therapy ( P=0.192, P=0.163). However, Cox multivariate analysis showed that NPS was an independent risk factor for overall survival (OS) and disease-free survival (DFS) of LARC ( P=0.009, P=0.003), and hierarchical analysis suggested that LARC patients with lower NPS score obtained better prognosis. Besides NPS, tumor size was also an independent risk factor for OS, and tumor size and N stage were the independent risk factors for DFS. Conclusion:NPS has no correlation with tumor regression or pCR for LARC after neoadjuvant chemoradiotherapy, whereas it could serve as an effective predictor for long-term prognosis of LARC.
