Objective To analyze the current status of medical services in secondary and tertiary hospitals in Shandong Province based on DRG,and to provide effective support for the implementation strategies of bidirectional referral.Methods The DRG group was used to analyze 42.348 3 million cases from 75 secondary hospitals and 69 tertiary hospitals in Shandong Province from 2019 to 2023.Experts were organized to establish standards for bidirectional referral of diseases.Results(1)35 high-frequency DRG disease groups with diagnosis,treatment ability and medical resources in secondary hospitals were selected,(2)The medical expenses and medical quality in the high-frequency DRG disease groups within secondary hospitals were lower than those in tertiary hospitals,(3)To develop standardized referral standards and programs with esophageal cancer as an example.Conclusion It is urgent to triage patients gradually and accurately through disease classification management,and formulate disease diagnosis and treatment plans and bidirectional referral standards to improve the medical quality of secondary hospitals.

Objective:To investigate the expression of p21-activated kinase 2 (PAK2) in laryngeal squamous cell carcinoma and its relationship with the clinicopathological characteristics and chemosensitivity of patients.Methods:Transcriptome sequencing (RNA-seq) data for laryngeal squamous cell carcinoma were downloaded from the Cancer Genome Atlas (TCGA) database, and 123 patients were included in the study (12 cases had cancer tissues and normal tissues data, and the remaining 111 only had cancer tissues data). Differential expression of PAK2 in cancer and para-cancer tissues was analyzed by using R software, and the potential function of PAK2 in laryngeal squamous cell carcinoma was investigated by using the Kyoto Encyclopedia of Genes and Genomes (KEGG) database signaling pathway enrichment. A total of 34 patients with primary laryngeal squamous cell carcinoma tissues and corresponding para-carcinoma 34 tissue specimens who underwent surgical resection were retrospectively selected from Chaoyang Central Hospital between April 2016 and June 2021, and 20 cases of normal laryngeal mucosa tissues were selected as the controls. Immunohistochemistry was used to detect the expression of PAK2 in various tissues, and its correlation with clinicopathological factors was analyzed. A total of 35 supraglottic primary laryngeal squamous cell carcinoma patients were retrospectively collected before induction chemotherapy during the same period, including 20 patients sensitive to chemotherapy and 15 patients resistant to chemotherapy. Real-time fluorescence quantitative polymerase chain reaction (qRT-PCR) was used to detect the relative expression level of PAK2 mRNA in cancer tissues.Results:Analysis of TCGA database data showed that PAK2 expression was increased in cancer tissues compared with that in para-cancer tissues ( P = 0.012); KEGG database signaling pathways showed that the high expression of PAK2 in laryngeal squamous cell carcinoma was related to signal transduction pathways, cell cycle, and cancer. Immunohistochemistry showed that the proportion of PAK2 positive in 34 cases of laryngeal squamous cell carcinoma tissues was higher than that in adjacent tissues and normal tissues [58.82% (20/34) vs. 0.03% (1/34), 0 (0/20), all P < 0.001]. There were statistically significant differences in the proportion of PAK2 positive patients stratified with different degrees of differentiation [high differentiation vs. low or middle differentiation: 33.33% (6/18)vs. 87.50% (14/16)], lymph node metastasis [presence vs. absence: 90.91% (10/11) vs. 43.48% (10/23)], TNM staging [stage Ⅲ-Ⅳ vs. stage Ⅰ-Ⅱ: 82.35% (14/17) vs. 35.29% (6/17)] (all P < 0.05), and PAK2 positive patients were not associated with clinical type, tumor size, smoking history, drinking history, and age (all P > 0.05). qRT-PCR showed that the relative expression level of PAK2 mRNA in the chemotherapy-resistant group was higher than that in the chemotherapy-sensitive group (3.89±0.12 vs. 0.78±0.23, P < 0.001). Conclusions:The expression level of PAK2 in laryngeal squamous cell carcinoma tissues is increased, and the high expression of PAK2 is closely related to the malignant clinical characteristics of patients with laryngeal squamous cell carcinoma. The high expression of PAK2 may indicate the insensitivity to traditional chemotherapy regimens, and PAK2 may be a potential gene that targets and regulates the chemosensitivity of laryngeal squamous cell carcinoma.

OBJECTIVE: To summarize the clinical effect of TPF regimen in the treatment of hypopharyngeal carcinoma and explore various clinical factors affecting treatment efficacy. METHOD: The clinical data of 20 cases with hypopharyngeal carcinoma, who received TPF treatment, were analyzed retrospectively. After two courses of chemotherapy, based on radiographic outcomes, next treatment plan was developed. To sum up the clinical information, including the clinical type, patterns of tumor growth, pathologic type, tumor stage, lymph node metastasis, age and so on. To analyze possible influencing factors affecting curative effect. RESULT: (1) After 20 cases with hypopharyngeal carcinoma received two courses of TPF treatment, the effect was evaluated. Objective response rate was 65%. (2) In patients with hypopharyngeal carcinoma, the efficacy of TPF therapy was significantly related to the clinical type, patterns of tumor growth and pathologic type; there was no statistical significance in tumor stage, lymph node metastasis and age. CONCLUSION According to the clinical type, patterns of tumor growth and pathologic type of hypopharyngeal carcinoma, resistance to chemotherapy in hypopharyngeal carcinoma can be assessed, which provides important basis for designing individualized treatment plan.
