Objective:To investigate the personnel, equipment, new technology of various radiotherapy units in Gansu Province, aiming to deeply understand the current status of radiotherapy in Gansu Province.Methods:From March 2023 to March 2024, the data of personnel, equipment and technology of different radiotherapy units in Gansu Province were investigated via online questionnaire survey and offline field visits by Gansu Provincial Quality Control Center for Radiation Oncology. The questionable data were reviewed, logical verification and outlier identification were conducted, and all information was entered according to the principle of double entry. Qualitative data were described by frequency (percentage).Results:As of March 2024, there are 26 radiotherapy units in Gansu Province, including 7 units in Lanzhou, capital city of Gansu Province and none in Linxia Hui Autonomous Prefecture and Gannan Tibetan Autonomous Prefecture. The ratio of radiotherapy physicians and physicists was 2.71 vs. 1, lower than the national level of 3.51 vs. 1. Radiotherapy physicians with intermediate and senior titles accounted for 66.2%, 54% for physicists with intermediate and senior titles and 34.0% for therapists with intermediate and senior titles, respectively. There were 1.70 accelerators per million population in Gansu Province. Among 42 accelerators in Gansu Province, 40 were linac and 2 heavy ion accelerators. In Lanzhou, 7 radiotherapy units had 17 linac, and the remaining 11 cities had 23 linac. All 40 linac could perform 3D conformal radiotherapy and intensity-modulated radiotherapy. The high-end equipment could apply advanced technologies such as volumetric modulated arc radiotherapy, stereotactic body radiotherapy, optical surface-guided radiation therapy and adaptive radiation therapy, etc. Relevant data in this survey were improved compared with those in the national surveys conducted in 2006, 2015 and 2019. Conclusions:The radiotherapy status has developed in Gansu Province, whereas uneven development still exists among regions. According to the actual demands of equipment, talents and technology in each region, the structural adjustment should be oriented to the underdeveloped cities and counties in the province to meet the local medical needs.

The advent of the bioeconomy era is triggers a new wave of technology and industrial revolution. Bioeconomy has become the commanding heights that major developed countries and emerging economies try to seize. This paper analyzes the spatiotemporal characteristics of global bioindustry development from four perspectives: biomedical industry, genetically modified crop planting industry, bioenergy industry, and bio-based chemical industry. Then it summarizes the main characteristics of the development of the global bioindustry, and further put forward policy recommendations for the bottleneck problems in the development of China's bioindustry, which can guide the future development of China's bioeconomy.

The era of bioeconomy has ushered in a new wave of technological and industrial revolution for mankind. The strategic deployment for the bioindustry in China has achieved remarkable results. However, there are still problems such as unbalanced regional development in the process of bioindustry development. In order to comprehensively assess the current situation of the competitiveness of the bioindustry in various regions of China, the assessment indicator system of the overall competitiveness of the bioindustry is constructed from the perspective of the four sub-industries of biomedicine, bioenergy, bioagriculture and bio-based industry. The weight of each assessment indicator is determined by the analytic hierarchy process. According to geographical administrative division and regional economic relations, an empirical analysis of the comprehensive competitiveness score of the bioindustry in seven regions of China is carried out. The assessment results show that the competition of bioindustry in various regions of China presents a gradient distribution in space. In view of this, relevant policy recommendations are put forward from four aspects: (1) implementing the strategy of rural revitalization, (2) implementing the strategy of regional coordinated development, (3) deepening the supply-side structural reform for the bioindustry, and (4) establishing regional unified information collaboration network system.

Objective To explore the expressions and clinical values of pro-gastrin-releasing peptide(ProGRP) and carbohydrate antigen 72-4 (CA72-4) in patients with gastric cancer.Methods Ninety patients with gastric cancer and fifty healthy subjects were selected from January 2014 to December 2016 in our hospital.Serum levels of ProGRP and CA72-4 were detected by electrochemiluminescence.The relationships between ProGRP and clinicopathological characteristics,postoperative recurrence and CA72-4 were analyzed.The diagnostic values of ProGRP and CA72-4 in gastric cancer were analyzed by receiver operating characteristic (ROC) curve.Results The expressions of ProGRP and CA72-4 in patients with gastric cancer were (249.3 + 28.9) pg/ml and (148.8 + 33.5) U/ml respectively,which were significantly higher than those of healthy subjects [(14.4 ± 7.6) pg/ml and (3.8 ± 1.4) U/ml],and the differences were statistically sigificant (t =56.320,P ＜ 0.001;t =30.504,P ＜ 0.001).The expression of ProGRP in TNM stage Ⅲ-Ⅳ [(269.1 ±30.9)pg/ml] was obviously higher than that in stage Ⅰ-Ⅱ [(198.5 +23.9)pg/ml],with a significant difference (t =11.200,P ＜ 0.001).The expression of ProGRP in patients with lymph node metastasis [(259.9 ±31.4)pg/ml] was significantly higher than that in patients without lymph node metastasis [(190.3 ±26.8)pg/ml],with a significant difference (t =9.500,P ＜ 0.001).The expression of ProGRP in patients with postoperative recurrence after one year [(181.3 ± 21.7)pg/ml] was higer than that in patients without postoperative recurrence [(26.1 ± 12.8)pg/ml],with a significant difference (t =31.830,P ＜ 0.001).There was a positive correlation between serum ProGRP and CA72-4 (r =0.792,P =0.012).According to the ROC curve,the cut-off point of ProGRP was 23.6 pg/ml,and the diagnostic sensitivity was 80.0％,the specificity was 70.0％.The cut-off point of CA72-4 was 11.2 U/ml,and the diagnostic sensitivity was 60.0％,the specificity was 89.0％.The sensitivity and specificity diagnostic value of combined detection were 89.7％ and 94.8％,better than those of individual detection (x2 =6.028,P =0.009;x2 =4.675,P =0.031).Conclusion ProGRP and CA72-4 are highly expressed in the serum of gastric cancer patients,with a positive correlation.The combined detection of ProGRP and CA72-4 can improve the diagnostic sensitivity and specificity.ProGRP is significantly correlated with tumor stage,lymph node metastasis and prognosis,which may be a mew target for prevention and treatment of gastric cancer.

Purpose:To study the clinical value of preoperative examination of P16 protein , immunohistochemical method was used to examinate the expression of the protein in tissues obtained through the fibrobronchoscopic brushing and biopsy.Methods:All of the patients who found lesions of lung by radiology were gotten the fibrobronchoscopy to get the spicements. All of the specimens were examinted for expression of P16 protein. The expressions of P16 protein in lung carcinoma group , benign lung disease group and blind biopsy group were compared.Results:The positive expression rates of p16 protein of lung carcinoma group , lung benign disease group and blind biopsy groups are : 55.0%, 95.0% and 62.5%. Conclusions:Difference was found between malignant and benign lung diseases.Examination of p16 protein expression for blind biopsy groups has some values in diagnosis of lung carcinoma.
