OBJECTIVE To conduct a clinical comprehensive evaluation of five marketed thrombopoietin receptor agonists （TPO-RA） approved in China， providing quantitative evidence for drug selection and therapeutic decision-making in medical institutions. METHODS Relevant data on Romiplostim for injection， Eltrombopag olamine tablets， Herombopag olamine tablets， Avatrombopag maleate tablets， and Lusutrombopag tablets were collected. Based on the Chinese Rapid Guide for Drug Evaluation and Selection in Medical Institutions （Second Edition）， 12 formulations of these five TPO-RA were scored quantitatively and comparatively across five dimensions： pharmacological characteristics， efficacy， safety， cost-effectiveness， and other attributes. RESULTS The comprehensive scores of the 12 formulations ranged from 62.56 to 75.50 points， with most scoring ≥70 points. Using the highest-scoring formulation for each generic name as a representative， the overall rankings of the five TPO-RA were as follows： Lusutrombopag tablets （75.50 points）， Eltrombopag olamine tablets （75.10 points）， Avatrombopag maleate tablets （70.40 points）， Romiplostim for injection （63.93 points）， and Herombopag olamine tablets （63.52 points）. Lusutrombopag tablets scored relatively high in pharmacological characteristics， safety， and cost-effectiveness， while Eltrombopag olamine tablets performed well in efficacy and cost-effectiveness. The other formulations showed varying scores across evaluation dimensions. CONCLUSIONS The five TPO-RA demonstrate favorable overall clinical value， with Lusutrombopag tablets and Eltrombopag olamine tablets ranking higher in comprehensive scores， these two drugs should be prioritized in drug selection and formula optimization by medical institutions.

Objectives:This study aimed to explore the association between perceived mental stress (MS), lymphocyte subset variations, and coronary lesion severity in patients with coronary artery disease (CAD).Methods:Patients with CAD were enrolled in this study from September 2023 to May 2024. Perceived Stress Scale-14 (PSS-14) was used to evaluate MS during the last 1 month. Lymphocyte subsets were analyzed, including the percentage and absolute counts of CD3 +, CD3 +CD4 +, CD3 +CD8 +, CD3 -CD19 +, CD3 -CD56 +16 +, and the Th/Ts ratio. Statistical analysis was conducted using SPSS 24.0. Results:This study recruited patients with 323 CAD, with an average age of 61 (56, 68) years, including 203 males and 120 females. According to the PSS-14, a score of 14-42 and 43-70 were categorized as normal and increased MS, respectively. Patients with CAD with increased MS had significantly higher Gensini scores than those with normal MS [37(19,64) vs. 28(12,50), Z=-2.19, P=0.029]. Male CAD patients with increased MS exhibited significantly higher Gensini scores [39(20, 58) vs. 26(12, 45), Z=-2.37, P=0.018], levels of CD3 +CD8 +%[28.3%(23.6%,36.6%) vs. 25.9%(21.0%,32.4%), Z=-2.05, P=0.041], and CD3 +CD8 +absolute value [485 (346, 675) vs. 396 (309, 510) cells/μl, Z=-2.55, P=0.011] than those with normal MS. In male patients with CAD, a positive correlation was observed between Gensini scores (correlation coefficient: 0.181, P=0.011), PSS-14 scores, and CD3 +CD8 +absolute value (correlation coefficient: 0.162, P=0.038). Conclusion:This study reveals a positive correlation between MS and coronary stenosis severity, with notable sex differences. In male patients with CAD, higher levels of MS are associated with more severe coronary stenosis. The potential underlying mechanism may involve the regulation of lymphocyte subsets .

Objective:To investigate the influencing factors for gastroesophageal reflux disease (GERD) after laparoscopic Heller-Dor surgery for esophageal achalasia.Methods:The retrospective case-control study was conducted. The clinical data of 210 patients with esophageal achalasia who were admitted to Shanxi Provincial Cancer Hospital from January 2021 to December 2023 were collected. There were 119 males and 91 females, aged (47±12)years. All patients underwent laparoscopic Heller-Dor surgery. Observation indicators: (1) surgical situations; (2) follow-up; (3) influencing factors for GERD after laparoscopic Heller-Dor surgery; (4) development and evaluation of a predictive model for GERD after laparoscopic Heller-Dor surgery. Univariate and multivariate analyses were performed using stepwise Logistic regression. Results of multivariate analysis were used to construct a nomogram in predicting GERD. The predictive performance was assessed using the area under the receiver operating characteristic curve. The calibration curve was used to evaluate the accuracy of the model, and the decision curve was used to assess the overall net benefit of the model.Results:(1) Surgical situations. All 210 patients underwent laparoscopic Heller-Dor surgery. The operation time was (128±31)minutes, volume of intraoperative blood loss was (25±9)mL, and length of lower esophageal sphincter (LES) myotomy was (5±3)cm. The length of low esophageal myotomy >6 cm was performed in 49 patients, and length of gastric fundus myotomy >2 cm was performed in 58 patients. Intraoperative mucosal perforation occurred to 3 patients and was repaired intraoperatively. One patient required conversion to open surgery. Postoperative complications occurred in 18 patients. The duration of postoperative hospital stay was (4.3±2.4)days. (2) Follow-up. All 210 patients were followed up for 4(range,7-33)months after surgery. During follow-up, 32 pati-ents had GERD, including 17 cases presenting dysphagia and 25 cases presenting acid regurgitation and heartburn (the same patient may have two symptoms). There were 29 cases with body mass index (BMI) >28 kg/m2. Symptom severity scores of 210 patients showed heartburn of 0.6(range, 0-3.0), reflux of 0.7(range, 0-3.0), chest pain of 0.4(range, 0-2.0), cough and hoarseness of 0.5(range, 0-2.0), nausea and vomiting 0.3(range, 0-2.0), dysphagia 0.8(range, 0-3.0). The LES pressure was (15±8)mmHg (1 mmHg=0.133 kPa), LES relaxation rate was 81%±13.0%, and integrated relaxation pressure was (9±6)mmHg. Esophageal manometry classification showed type Ⅰ, Ⅱ, and Ⅲ in 0, 8, and 0 patients, respectively. There were 208 patients achieved symptom relief after drug or symptomatic treatment. Only two patients with severe symptoms were unresponsive to medication and subsequently underwent surgery at another hospital, with symptoms improving postoperatively. (3) Influen-cing factors for GERD after laparoscopic Heller-Dor surgery. Results of multivariate analysis showed that male, smoking history, length of lower esophageal myotomy >6 cm, and postoperative BMI >28 kg/m2 were independent risk factors for GERD after laparoscopic Heller-Dor surgery ( odds ratio=4.02, 6.34, 5.41, 7.38, 95% confidence interval as 1.50-10.78, 3.31-12.31, 1.77-13.47, 2.80-15.42, P<0.05). (4) Development and evaluation of a predictive model for GERD after laparoscopic Heller-Dor surgery. A predictive nomogram model for GERD was constructed based on the results of multivariate analysis. The receiver operating characteristic curve of predictive nomogram model for GERD had an area under curve of 0.91 (95% confidence interval as 0.82-0.97), demonstrating good discrimination. The calibration curve showed good agreement between predicted and observed probabilities, with a mean absolute error of 0.033. The decision curve demonstrated that within a threshold probability range of 0.2-0.8, the predictive model had greater net benefit than "treat-all" or "treat-none" strategies, indicating clinical utility of this model in clinical decision. Conclusions:Male, smoking history, length of lower esophageal myotomy >6 cm, and postoperative BMI >28 kg/m2 are independent risk factors for GERD after laparoscopic Heller-Dor surgery for esophageal achalasia. The predictive model for GERD after laparoscopic Heller-Dor surgery based on these factors shows strong predictive accuracy.

Background:Colorectal cancer(CRC)is a major cause of cancer death worldwide,and about 30%to 35%of CRC arises from the serrated pathway.Aims:To analyze the clinicopathological and histomorphological characteristics of colorectal superficially serrated adenoma(SuSA),and to investigate the malignant transformation potential of SuSA and further elucidate the role of RSPO2 and RSPO3 in its carcinogenic mechanism.Methods:A total of 169 serrated colorectal lesions confirmed pathologically and fulfilling the inclusion criteria were collected from Shanxi Bethune Hospital from February 2019 to May 2023.Among them,there were 84 cases of SuSA,23 sessile serrated lesions(SSL),32 traditional serrated adenomas(TSA),and 30 hyperplastic polyps(HP).Thirty-nine cases of tubular adenoma(TA),32 CRC,and 33 normal colorectal mucosal tissues were served as controls.The clinicopathological and histomorphological parameters were collected and recorded.Immunohistochemical staining was used to detect the protein expressions of RSPO2,RSPO3,p53,MLH1 and β-catenin.Results:Patients with SuSA were male predominance,with a mean age of 51.89 years.The average diameter of the lesions was 0.20 cm,predominantly located in the left colon and rectum,and frequently complicated with other polyps/adenomas.The histomorphological features of SuSA were as follows:the glandular necks and crypt bases exhibited straight tubular structure with low-grade dysplasia;the superficial layer demonstrated a serrated architecture,with or without dysplasia,and contained a variable number of goblet cells.Immunohistochemically,there were no statistically significant differences in RSPO2,RSPO3,and p53 expressions between SuSA and TSA(all P>0.05).A strong positive correlation was observed between RSPO2 and RSPO3 in colorectal lesions,excluding HP.Expressions of MLH1 and β-catenin showed no statistically significant differences between SuSA and other colorectal lesions(all P>0.05).Conclusions:SuSAs are more common in males,occur mostly in the left colon and rectum,and are often associated with other polyps/adenomas.They might be precursors of KRAS-mutated TSA and microsatellite stable CRC with high malignant potential.RSPO2 and RSPO3 might play an important role in the carcinogenesis of SuSA.
