Radiotherapy is one of the main treatment methods for malignant tumors, which can cause the radiation damage to normal tissues. Radiation-induced skin injury (RISI) is one of the main adverse reactions caused by radiotherapy. The main clinical manifestations of RISI are dermatitis, ulcer, erosion and necrosis, which seriously affect the quality of life and treatment effect of tumor radiotherapy patients, and even affect the overall survival of patients. The pathological mechanism of RISI is still unclear. Some studies have shown that inflammation and oxidative stress are the main causes of RISI. RISI can be divided into acute and chronic RISI according to the different onset time, and different treatment strategies can be formulated according to the severity of the injury. In this article, clinical manifestations, classification, pathogenesis, prevention and treatment of RISI are comprehensively summarized.

Objective To discuss the application value of video health education mode in patient's self-maintenance of totally implantable venous access port(TIVAP).Methods A total of 208 patients,who received implantation of TIVAP at the Second Affiliated Hospital of Naval Military Medical University of China From September 2021 to December 2022,were enrolled in this study.The patients were divided into control group(n=108)and observation group(n=100).Traditional health education was conducted for the patients of the control group,while on the basis of traditional health education an additional video health education based on visual communication theory was carried out for the patients of the observation group.Evaluation of self-care ability(ESCA)was used to evaluate the self-care ability before the intervention and 6 months after the implantation of TIVAP in the two groups.The complications,the incidence of adverse events,and the indwelling duration of the infusion port were compared between the two groups.Results Before intervention,the differences in each dimension score and total score of ESCA table between the two groups were not statistically significant(all P＞0.05).After intervention,the each dimension score and total score of ESCA table in the observation group were significantly higher than those in the control group(all P＜0.05).After intervention,both the total incidence of complications and the total incidence of adverse events in the observation group were remarkably lower than those in the control group(both P＜0.05),besides,the indwelling duration of the infusion port in the observation group was obviously longer than that in the control group.Conclusion The use of video health education mode can significantly improve the self-care ability of patients carrying a TIVAP,reduce the incidence of complications and adverse events,and extend the effective duration of TIVAP.Therefore,it is an effective health education mode.

Lung cancer is the leading cause of cancer-related deaths， and standard treatments for lung cancer， including surgery， radiotherapy， chemotherapy， targeted therapy， and immunotherapy， have shown significant clinical effects. However， current available treatment strategies are still unable to cure the disease. Since the majority of lung cancer patients are diagnosed at an advanced stage， surgical options are often lost， and the primary approach is typically a combination of radiotherapy and chemotherapy. However， the adverse reactions associated with these treatments limit their effectiveness and application， and the damage caused to normal tissues is often more severe than that inflicted on the tumor. Currently， traditional Chinese medicine （TCM） has been used as part of combination therapy for cancer treatment due to its unique system of syndrome differentiation， flexible compatibility， and safety and efficacy. TCM prescriptions and single drugs with multiple components and targets can simultaneously regulate multiple pathways. As reported， among numerous pathways involved in the regulation of lung cancer， the nuclear factor-κB （NF-κB） signaling pathway plays a key role in inducing cell transcription and is one of the main pathways involved in the occurrence and development of lung cancer. It can specifically regulate inflammatory responses， cell proliferation， apoptosis， invasion and metastasis， angiogenesis， and multidrug resistance in lung cancer. TCM prescriptions and single drugs can inhibit lung cancer cell proliferation， invasion， and metastasis， induce apoptosis and autophagy in lung cancer cells， suppress angiogenesis， regulate immune function， and treat multidrug resistance by regulating the NF-κB signaling pathway. Therefore， they play a role in intervening in lung cancer. However， there is currently a lack of systematic literature research that comprehensively summarizes and elucidates these aspects in China and abroad. Therefore， it is important to provide a systematic elucidation of the mechanism underlying the regulation of the NF-κB signaling pathway in lung cancer and review TCM interventions in lung cancer based on the NF-κB signaling pathway. This study is expected to provide references for the clinical application of lung cancer therapeutic drugs and the development of new drugs.

Objective:To observe the efficacy of 3D printing-assisted hematoma puncture and drainage in the treatment of hypertensive intracerebral hemorrhage and to explore the factors affecting postoperative brain dysfunction.Methods:A retrospective Case-control study was conducted to select 168 hypertensive intracerebral hemorrhage patients who were treated with 3D printing assisted hematoma puncture and drainage in the People′s Hospital of Yuechi County from January 2020 to September 2022 as the observation group, and 125 hypertensive intracerebral hemorrhage patients who were treated with CT guided hematoma puncture and drainage in the People′s Hospital of Yuechi County at the same time as the control group. The clinical efficacy of the two groups of patients was compared. According to the occurrence of postoperative brain dysfunction, the patients in the observation group were divided into normal brain function group ( n=121) and brain dysfunction group ( n=47). The clinical data of age, preoperative cerebral hernia, blood loss, ventilator-assisted ventilation, postoperative Glasgow coma index score (GCS) and postoperative complications were compared between the two groups. Multivariate Logistic regression was used to analyze the factors affecting postoperative brain dysfunction in the observation group, and a line chart model was constructed and its predictive efficiency was evaluated. The measurement data of normal distribution is expressed as mean ± standard deviation ( ± s), and independent sample t-test is used for inter group comparison. Chi-square test was used for comparison between count data groups. Results:The proportion of the drainage tube in the hematoma, hematoma clearance rate at 3 and 7 days after surgery, total effective rate of treatment, and GCS score at 1 week after surgery in the observation group were 88.69%(149/168), 54.17%(91/168), 96.43%(162/168), 92.86%(156/168), and 10.72±3.45, respectively, the control group was 75.20%(94/125), 36.80%(46/125), 81.60%(102/125), 76.80%(96/125), and 9.08±3.22, respectively, the difference between the two groups was statistically significant ( P<0.05). Advanced age ( OR=1.983, 95% CI: 1.169-2.732, P=0.017), preoperative cerebral hernia ( OR=1.532, 95% CI: 1.113-2.139, P=0.029), bleeding volume ≥ 50 mL ( OR=2.538, 95% CI: 1.802-3.347, P=0.003), postoperative GCS score 3-5 ( OR=2.874, 95% CI: 2.265-3.449, P<0.001), postoperative hypoxemia ( OR=2.251, 95% CI: 1.673-2.842, P=0.010) and postoperative chronic hydrocephalus ( OR=1.642, 95% CI: 1.214-2.021, P=0.022) were risk factors for postoperative brain dysfunction, while ventilator-assisted ventilation ( OR=0.656, 95% CI: 0.132-0.828, P=0.038) was protective factors. The internal verification of the line chart model by Bootstrap resampling method shows that the model has high differentiation, accuracy and validity. Conclusion:The application of 3D printing-assisted localization in hematoma puncture and drainage can improve the puncture condition and the hematoma clearance rate and clinical effect of patients with hypertensive intracerebral hemorrhage. Advanced age, preoperative cerebral hernia and bleeding volume are related to postoperative brain dysfunction. Clinical attention should be paid to patients with risk indicators of postoperative brain dysfunction.

A split-plot experiment was conducted to study the optimum planting density of Nuomi yam in directional groove shallow cultivation. Nuomi yam was the main local cultivar of Dioscorea. The study of this paper may help to give valuable instructions of local production. Three different planting densities and shallow groove diameter were designed in the experiment. The results showed that the fresh weight of aerial part per plant, yield and planting benefit of Nuomi yam tuber were the highest when the planting density was 12 000 plants/hm~2 and the diameter of shallow growth groove was 11.0 cm, while they were the lowest when the planting density was 22 500 plants/hm~2 and the diameter of shallow growth groove was 7.5 cm. Along with the increase of planting density, the fresh weight of aerial part, tuber, fresh yield, benefit and commercial tuber rate of Nuomi yam also decreased. The commercial tuber rate of Nuomi yam of 11.0 cm diameter in shallow growing pot was the highest, while it was the lowest with no shallow growing pot. On the contrary, the content of amylopectin and mucin was the highest when there was no shallow groove, and was the lowest when the diameter of shallow groove was 7.5 cm, although there was no significant difference between the two treatments. Therefore, Nuomi yam with the directional cultivation combination of planting density of 12 000 plants/hm~2 and shallow groove diameter of 11.0 cm showed high yield, good appearance quality, high planting benefit and no obvious adverse effect on internal quality.

OBJECTIVE: To observe the effect of acupoint stimulation on the quality of recovery in patients with radical thyroidectomy under the concept of enhanced recovery after surgery (ERAS). METHODS: A total of 62 patients with radical thyroidectomy were randomized into an observation group and a control group, 31 cases in each one. In both of the two groups, general anesthesia with tracheal intubation was applied, the same anesthesia induction and maintenance medication were given. In the observation group, auricular point pressing with magnetic beads was adopted at bilateral shenmen (TF) and transcutaneous electrical acupoint stimulation (dilatational wave, 2 Hz/100 Hz in frequency, 6 to 12 mA) was performed at bilateral Hegu (LI 4) and Neiguan (PC 6) from 30 min before anesthesia induction to the end of the anesthesia. In the control group, medical adhesive plaster was pasted at bilateral shenmen (TF) and the electrodes were plastered at bilateral Hegu (LI 4) and Neiguan (PC 6) with no corresponding stimulation. In both of the two groups, visual analogue scale for anxiety (VAS-A) score was observed to evaluate the anxiety severity before anesthesia induction; the total intraoperative dosages of sufentanil, remifentanil and propofol were recorded; the numerical rating scale (NRS) score was used to assess the pain severity of instant time (T0) and 30 min (T1) of entering post-anesthesia recovery room (PACU), motor and static mode at 2 h (T2), 6 h (T3), 12 h (T4), 24 h (T5) after surgery; time of first anal exhaust, time of getting out of bed after surgery, total hospitalization time and the incidences of postoperative nausea and vomiting were observed; the quality of recovery was assessed by the 40-item quality of recovery score (QoR-40). RESULTS: The VAS-A score and the total intraoperative dosage of remifentanil in the observation group were reduced compared with the control group (<0.05). The NRS scores at T0-T4 in the observation group were lower than those in the control group (<0.01, <0.05), while the difference between the two groups in NRS score at T5 was not significant (>0.05). The time of first anal exhaust and getting out of bed after surgery in the observation group were advanced than those in the control group (<0.05), there was no significant difference between the two groups in total hospitalization time and incidences of postoperative nausea and vomiting (>0.05). Compared with the control group, the QoR-40 score was increased in the observation group (<0.05). CONCLUSION Acupoint stimulation can improve the preoperative anxiety in patients with radical thyroidectomy, reduce the intraoperative anesthetic dosage and postoperative pain, advance the time of anal exhaust and getting out of bed, improve the quality of postoperative recovery and enhance the recovery process.
