Nonunion of osteoporotic vertebral fractures (OVF), predominantly affecting the elderly, can lead to intractable pain, vertebral collapse, progressive kyphotic deformity, and neurological impairment, significantly compromising patients′ quality of life. There exists considerable debate on diagnosis and management of OVF, encompassing key issues such as clinical diagnosis and staging criteria for nonunion, surgical indications and procedure selection, and postoperative rehabilitation planning. Currently, there lacks standardized clinical guideline and expert consensus on the diagnosis and management of OVF nonunion in China. To address this gap, Minimally Invasive Surgery Group of Chinese Orthopedic Association, Osteoporosis Committee of Chinese Association of Orthopedic Surgeons, Prevention and Rehabilitation Committee for Osteoporosis of Chinese Association of Rehabilitation Medicine and Minimally Invasive Orthopedic Surgery Branch of China Association for Geriatric Care jointly organized domestic experts in spinal surgery, endocrinology, and rehabilitation to formulate the Clinical guideline for the diagnosis and treatment for nonunion of osteoporotic vertebral fractures ( version 2025), based on existing literature and clinical experience and adhering to principles of scientific rigor and practicality. The guideline provided 13 evidence-based recommendations encompassing diagnosis and treatment of OVF nonunion, aiming to standardize its clinical management.

The disclosure of medical service information is an important tool to help patients make medical decisions, improve the quality of medical services, and strengthen hospital supervision.The effectiveness of disclosing medical service information lies in meeting the needs of patients.The disclosure of medical service information in foreign countries started earlier that China. In order to strengthen the compatibility between medical service information and patient needs, some developed countries had used patient experience surveys, patient satisfaction surveys, and patient medical reports as the sources of public information.These countries publicly released information on medical quality, doctor-patient feedback, and social responsibility through official unified release platforms and processes, while establishing diversified and institutionalized regulatory mechanisms to create a good information disclosure system and mechanism for patient decision-making, service quality improvement, and government regulation.By drawing on the experience of medical service information disclosure in developed countries, the author proposed that we should carry out a comprehensive survey of patient needs, establish a convenient and transparent information disclosure platform, and establish a sound scientific regulatory mechanism, so as to provide reference for promoting the establishment of a patient demand oriented medical service information disclosure mechanism in China

OBJE CTIVE To provide reference for improving rational drug use in medical institutions and strengthening individualized rational drug use monitoring. METHODS The hospital information system （HIS）was used to retrieve the patient ’s medical information and the doctor ’s medical information ；on the basis of pre-examination of prescriptions ，the chronic disease medication monitoring and visiting frequency monitoring modules were added to construct individualized rational drug use monitoring platform. Taking hypoglycemic drugs as an example ，the number of patients who were prescribed the drug ≥3 times a month in Karamay Central Hospital （hereinafter referred to as “our hospital ”）was compared before and after the operation of the individualized rational drug use monitoring platform （Jan. to Apr. 2018 regarded as before operation ，Jan. to Apr. 2019 and 2021 regarded as after operation ）. At the same time ，the number of risk prescriptions （repeatedly prescribing the same drug ≥3 times a day）and unreasonable prescriptions after the operation of the individualized rational drug use monitoring platform （Jan. to Apr. 2019 and Jan. to Apr. 2021）in our hospital were compared. RESULTS The proport ion of patients who were over prescribed Diformin tablets from Jan. to Apr. in 2021 was lower than the same period in 2018 significantly（16.65％ vs. 27.17％，P＜0.05）. From Jan. to Apr. 2019，35.3％ of the risk prescriptions in our hospital were unqualified prescriptions ；in the same period of 2021， the proportion of unqualified prescriptions in risk prescriptions in our hospital decreased to 12.82％ ，which was statistically significant compared with 2019（P＜0.05）. CONCLUSIONS Based on the actual situation of patients ，our hospital establishes the individualized rational drug use monitoring platform by using HIS to meet the actual needs of clinical drug use. The use of the platform has significantly reduced the number of patients visiting doctors many times and unreasonable prescriptions ，and promotes rational drug use. At the same time ，the platform also further strengthens the prescription review system of our hospital and improves the level of pharmaceutical care.

Objective: To compare the clinical effects of laparoscopic repair and open repair of gastroduodenal ulcer perforation. Methods: Retrospective analysis was performed on 117 patients with perforated gastroduodenal ulcer admitted to Sijing Hospital of Shanghai Songjiang District from October 2005 to February 2018, including 86 males and 31 females. The average age was 35.56 years with a range from 17 to 68 years. Patients were divided into two groups according to different surgical methods: laparoscopic group (n=56) and open group (n=61). Patients in the laparoscopic group were received laparoscopic repair for perforated gastroduodenal ulcer, while patients in the open group received open repair for perforated gastroduodenal ulcer. Comparison of two groups of patients with operation time, intraoperative blood loss, postoperative first anal exhaust time, analgesic utilization rate, length of hospital stay, the body′s inflammatory response [preoperative and 24 h, 72 h, 120 h of postoperative peripheral white blood cell (WBC)], C-reactive protein level (CRP), postoperative complications (postoperative incision infection, incision dehiscence, gastric duodenal fistula, abdominal abscess, adhesion intestinal obstruction and lung infection). Measurement data were expressed as mean±standard deviation (Mean±SD), and t-test was used for comparison between groups; count data were compared by Chi-square test. Results: All the patients in the two groups successfully completed the operation, and there were no cases transferred to laparotomy in the laparoscopic group. Intraoperative blood loss[(15.3±9.5) ml vs (30.5±11.3) ml, P<0.001], time of first anal exhaust[(56.5±9.8) h vs (83.8±15.6) h, P<0.001], analygesic utilization rate (10.71% vs 52.46%, P<0.005), and length of hospital stay [(7.5±1.5) d vs (10.0±3.4) d, P<0.001] of the laparoscopic group were significantly better in the open group, the differences were statistically significant. The WBC and CRP at 24 h, 72 h and 120 h after surgery of the laparoscopic group were also significantly better than in the open group [WBC: 24 h, (14.55±3.44) ×10⁹/L vs (16.02±4.12) ×10⁹/L, P=0.020; 72 h, (10.25±2.32) ×10⁹/L vs (14.22±3.29) ×10⁹/L, P<0.001; 120 h, (8.12±3.11)×10⁹/L vs (11.58±2.33) ×10⁹/L, P<0.001. CRP: 24 h, (50.35±13.73) mg/L vs (80.11±13.56) mg/L, P<0.001; 72 h, (29.37±7.81) mg/L vs (53.57±8.05) mg/L, P<0.001; 120 h, (17.71±7.01) mg/L vs (34.35±7.72) mg/L, P<0.001], the differences were statistically significant. There was no significant difference in operation time and postoperative complications between the two groups (P>0.05). Conclusion Compared with open gastroduodenal ulcer perforation repair, laparoscopic gastroduodenal ulcer perforation repair surgery trauma are smaller, and the body′s inflammatory response are lighter, postoperative complications is no statistical significance, but will look from actual data, the cases of complications is less, is now a better surgical treatment of gastroduodenal ulcer perforation.

Due to the low molecular weight and simple structure, the production of specific antibodies against acrylamide is unavailable. In this study, a novel hapten was synthesized through the derivatization of acrylamide and 4-mercaptophenylacetic acid. The hapten was then coupled to carrier protein and used to immunize New Zealand rabbits. Polyclonal antibody which showed specific binding to the acrylamide derivative ( hapten) was obtained. The antibody was labeled with horseradish peroxidase ( HRP) and used to develop a direct competitive enzyme-linked immunosorbent assay ( dc-ELISA) . The dc-ELISA was used to determine the content of acrylamide derivative, and then transferred to the content of acrylamide. The assay showed an IC50 value of 45. 49 μg/L, a limit of detection of 3. 0 μg/L and the linear range of 9. 2-195 μg/L for acrylamide. The recovery of acrylamide from spiked food sample was determined ranging from 83 . 6% to 112 . 7%. Good correlations between the results of dc-ELISA and standard HPLC-MS/MS were obtained. The proposed dc-ELISA is suitable for the determination of acrylamide in food samples.
