Objective To investigate the current status of treatment for patients with convulsive epilepsy in rural areas of Heilongjiang Province， China and the efficacy of phenobarbital in the treatment of epilepsy， and to evaluate the effect of the epilepsy prevention and management project in rural areas. Methods EpiData， EXCEL， and SPSS 19.0 were used for data entry， processing， and statistical description to analyze the current status of epilepsy treatment in rural areas， the dose of phenobarbital， and the frequency of seizures. In the epilepsy prevention and management project of Heilongjiang Province in 2015—2020， a total of 908 patients with convulsive epilepsy were enrolled in the phenobarbital treatment group， and after standardized treatment and follow-up management， 698 patients were followed up for at least 12 months. Results The gap rate of rural epilepsy treatment in Heilongjiang Province was 56.39%. After one year of standardized treatment， the frequency of seizures decreased from 23.86 times/year before enrollment to 3.11 times/year， showing a significant reduction. The response rate of epilepsy treatment was 68.19%， and the patients without previous standard treatment tended to have a better outcome than those who received standard treatment. Conclusion The current status of epilepsy treatment is not optimistic in rural areas of Heilongjiang Province， and there remains a large gap in epilepsy treatment. It is necessary to strengthen the training on the diagnosis and treatment of epilepsy among primary care physicians and implement the public education on the prevention and treatment of epilepsy， and since phenobarbital has a marked clinical effect in the treatment of epilepsy， it holds promise for further application in rural areas.

Objective:Proteins are closely associated with the development, progression, and immunotherapy of head and neck squamous cell carcinoma（HNSCC）. However, few clinical models utilize proteomics to predict prognosis and immunotherapy efficacy. In this study, we developed a protein prognostic model（PPM） to stratify survival outcomes and differential immunotherapy responses in HNSCC patients. Methods:Based on proteomic profiling, we constructed a PPM comprising 11 protein markers. Patients were classified into high-and low-risk groups according to PPM scores. The prognostic value of risk scores was evaluated using Cox regression analysis, and predictive accuracy was assessed via time-dependent receiver operating characteristic（ROC） curves. Additionally, we analyzed treatment responses to PD1/CTLA4 immunotherapy in PD1-or CTLA4-positive patients across risk groups. Results:Cox regression confirmed the risk score as an independent prognostic factor（HR=1.161, 95%CI 1.112-1.213, P<0.001）, with high-risk patients exhibiting significantly poorer survival than low-risk counterparts. The model demonstrated robust predictive accuracy, with 1-year and 3-year time-dependent ROC areas under the curve（AUC） of 0.713 and 0.707, respectively. In PD1/CTLA4-positive subgroups, low-risk patients showed superior immunotherapy responses compared to high-risk patients. Conclusion:The PPM can provide reliable prognostic stratification and preliminary guidance for immunotherapy in HNSCC. However, further clinical studies and basic experiments are needed for further verification.

Taking the Ligustrum lucidum extract as an example, this study investigated the influence of external mechanical forces under different processing conditions on the crystallographic solid form and the key parameter of drug dissolution rate, so as to provide guidance for the preparation and quality control of traditional Chinese medicine preparations. Under different pulverization and tableting conditions, the change of crystallographic solid form of L. lucidum extract was observed by polarizing light microscope. Meanwhile, the effect of this change on the dissolution rate was investigated, and the mathematical relationship between crystal content and dissolution rate was analyzed. The results showed that the process of ball milling and tableting had a significant impact on the crystallographic solid form of L. lucidum extract. The amorphous extract displayed crystal transformation, which induced a significant decline in dissolution rate. Further studies revealed that there was a negative linear relationship between crystal content and dissolution rate. The results of this study indicated that the crystallographic solid form transformation of traditional Chinese medicine extracts might occur during the preparation process, which may cause potential risks to the quality of traditional Chinese medicine preparations. It is suggested that we should pay attention to and strengthen the investigation of the crystallographic solid form during the preparation process, so as to guarantee the safety, effectiveness, and quality controllability of traditional Chinese medicine preparations.

To reduce the subjectivity and uncertainty present in the current international methods of drug value pricing when converting value into monetary prices,based on the hedonic pricing theory,it considers the post-negotiation price between manufacturers and payers as a reasonable price reference in the value pricing of Chinese patent medicine.By constructing an indicator system for the characteristics of Chinese patent medicine,it selects and measures the value characteristic variables that affect the price of Chinese patent medicine.It serves as the theoretical foundation and research basis for establishing a Hedonic price model between characteristic price variables and negotiation prices,thereby promoting the enhancement of rationality and objectivity in value-guided pricing of Chinese patent medicine.
