Objective:To investigate the incidence of cervical metastasis of oral and maxillary squamous cell carcinoma(SCC)and to define its impact factors.Methods:A retrospective study of patients with SCC of hard palate and maxillary alveolus treated by surgery from 2002 to 2011.Results:The incidences of cervical metastasis and occult metastasis were 17.2%(11 /64)and 9.8%(5 /51)re-spectively.pT classification and vascular invasion were correlated with cervical metastasis.Occult metastatic risk was significantly higher in pT4 patients.Presence of positive nodes impaired prognosis significantly.Conclusion:Overall and occult metastasis of oral and maxillary SCC were highly associated with pT classification.Routine and synchronous elective neck dissection(END)is recomend for the treatment of T4 lesions while observation is alternative for T1 -T3 lesions.

Objective To investigate the use of hepatoprotective drugs in China in recent years, and to put forward related suggestions. Methods The outpatient prescription data of hepatoprotective drugs were collected from 85 hospitals in 6 cities of China from 2015 to 2019, and a real-world data analysis was performed to analyze the payment method, issuing department, drug category, and use of hepatoprotective drugs. Results A total of 1 113 575 prescriptions were extracted, involving 38 hepatoprotective drugs such as compound glycyrrhizin, polyene phosphatidylcholine, and bicyclol. Hepatoprotective drugs were mainly in tertiary hospitals, and the highest number of prescriptions containing hepatoprotective drugs were observed in department of infectious diseases, department of gastroenterology, and department of tuberculosis. Anti-inflammatory hepatoprotective drugs accounted for the highest proportion of all prescriptions, mainly compound glycyrrhizin, polyene phosphatidylcholine, and bicyclol. Of all prescriptions, 253 429 (22.76%) had the combination of multiple hepatoprotective drugs, with the highest number of 6 drugs, among which polyene phosphatidylcholine combined with bicyclol accounted for the highest proportion. Conclusion There are large quantities of hepatoprotective drugs used by outpatients in China. At present, the hepatoprotective drugs are clinically applied rationally, but there are still some problems to be solved, such as the combination of drugs.

OBJECTIVE To conduct rapid health technology assessment （HTA） of ulinastatin （UTI）， and to evaluate the efficacy， safety and cost-effectiveness of UTI in the treatment of acute pancreatitis （AP）. METHODS Retrieved from PubMed， Embase， the Cochrane Library， CNKI， Wanfang database， CBM and official websites of HTA institutions， the systematic review （SR）/meta-analysis， economic evaluation and HTA reports of UTI in the treatment of AP were collected from the inception to Apr. 2024. Two researchers independently conducted screening， quality evaluation and data extraction according to the admission and exclusion criteria， and descriptive analysis was adopted to analyze and summarize the data. RESULTS A total of 19 studies were included， involving 15 SR/meta-analysis and 4 economic studies， and no HTA report was retrieved. In the treatment of AP， UTI showed clear advantages over conventional treatment alone in terms of improving the overall effective rate， shortening the recovery time of amylase， reducing the time required to relieve abdominal pain and distension， lowering the mortality rate， and decreasing the average hospital stay. Compared to other positive drugs （carbendate mesylate， octreotide， somatostatin， etc.）， its efficacy is similar， with a favorable safety profile. As far as the current research was concerned， UTI had obvious economic advantages over other positive drugs. CONCLUSIONS UTI is safe and effective in the treatment of AP， and has economic advantages.
