Objective To explore the correlation between osteocalcin (OCN) and visceral fat area (VFA) in overweight/obese population. Methods The data of 297 overweight/obese people who underwent health examinations in Health Management Department of Second Affiliated Hospital of Xi'an Jiaotong University from August 2021 to August 2024 were analyzed. According to the VFA value measured by InBody, the subjects were divided into an excessive group (VFA ≥100 cm²) and a normal group (VFA<100 cm2). The baseline data, glucose metabolism indicators, lipid metabolism indicators and OCN were compared between the two groups. Binary logistic regression analysis was used to analyze the independent risk factors affecting visceral fat deposition in overweight/obese people. Results According to the VFA value, there were 193 cases (64.98%) in the excessive group and 104 cases (35.02%) in the normal group. There were no statistical differences in gender, age and comorbidities between the two groups (P>0.05). The BMI, FPG, HbA1c, TC, TG, and LDL-C in the excessive group were higher than those in the normal group, while the HDL-C and OCN were lower than those in the normal group (P<0.05). Binary logistic regression analysis revealed that BMI, FPG, HbA1c, TC, TG and LDL-C were independent risk factors for visceral fat deposition in overweight/obese people, while HDL-C and OCN were protective factors (P<0.05). Conclusion Visceral fat deposition in overweight/obese people is closely related to OCN content, and is affected by abnormal glucolipid metabolism, which provides new ideas for the prevention and treatment of obesity-related diseases.

ObjectiveTo explore the clinical safety of Feilike Mixture （FLK） in the real world. MethodsThe safety of all children who received FLK from 29 institutions in 12 provinces between January 21，2021 and December 25，2021 was evaluated through prospective centralized surveillance and a nested case control study. ResultsA total of 3 035 juveniles were included. There were 29 research centers involved，which are distributed across 12 provinces，including one traditional Chinese medicine （TCM） hospital and 28 general hospitals. The average age among the juveniles was （4.77±3.56） years old，and the average weight was （21.81±12.97） kg. Among them，119 cases （3.92%） of juveniles had a history of allergies. Acute bronchitis was the main diagnosis for juveniles，with 1 656 cases （54.46%）. FLK was first used in 2 016 cases （66.43%），and 142 juvenile patients had special dosages，accounting for 4.68%. Among them，92 adverse drug reactions （ADRs） occurred，including 73 cases of gastrointestinal system disorders，10 cases of metabolic and nutritional disorders，eight cases of skin and subcutaneous tissue diseases，two cases of vascular and lymphatic disorders，and one case of systemic diseases and various reactions at the administration site. The manifestations of ADRs were mainly diarrhea，stool discoloration，and vomiting，and no serious ADRs occurred. The results of multi-factor analysis indicated that special dosages （the use of FLK）［odds ratio （OR） of 2.642， 95% confidence interval （CI） of 1.105-6.323］，combined administration： spleen aminopeptide （OR of 4.978， 95%CI of 1.200-20.655），and reason for combined administration： anti-infection （OR of 1.814， 95%CI of 1.071-3.075） were the risk factors for ADRs caused by FLK. Conclusion92 ADRs occurred among 3 035 juveniles using FLK. The incidence of ADRs caused by FLK was 3.03%，and the severity was mainly mild or moderate. Generally，the prognosis was favorable after symptomatic treatment such as drug withdrawal or dosage reduction，suggesting that FLK has good clinical safety.

Methods: From March 2020 to March 2023, 100 inpatients with DS were classified into groups A, B, C, and D based on the CARDS classification system. Preoperative radiological data were analyzed to measure the severity of central canal stenosis, facet joint arthropathy, intervertebral disc herniation, and spinal epidural lipomatosis, osteophyte formation, range of motion (ROM), and computed tomography value of the vertebral bodies. The radiological characteristics and clinical contraindications for OLIF were compared among the groups. Results: Of the 100 patients, 51% had clinical contraindications for OLIF, which included 85%, 25%, 62.5%, and 20% of patients in groups A, B, C, and D, respectively. Compared with group B, group A demonstrated greater severity of central canal stenosis, whereas group C showed a higher degree of facet joint arthropathy. More patients in groups A and C had severe central canal stenosis. Regarding the ROM results, group A had segmental stiffness, whereas group D presented relatively unstable slip segments. Conclusions Patients with different DS subtypes have varied radiological characteristics. Groups B and D are suitable candidates for OLIF. Most patients in group A are unsuitable for OLIF because of bony hyperplasia, severe spinal stenosis, and segmental stiffness.

OBJECTIVE To provide a reference for revising the safety content of traditional Chinese medicine（TCM） instructions. METHODS A systematic analysis was conducted on the relevant announcements on the revision of TCM instruction from 2013 to 2024， including the year of publication， drug name， drug formulation， announcement release time， and the average number of revisions made to three safety contents （contraindication， adverse drug reaction， and precaution）. According to the report data of national adverse drug reaction monitoring from 2013 to 2024， analyze the proportion of TCM in all adverse drug reactions， the composition ratio of adverse drug reaction of different dosage forms of drugs [TCM injection， oral TCM， other （topical） TCM]. RESULTS From 2013 to 2024， the National Medical Products Administration issued a total of 101 notices on the revision of TCM instruction， involving 241 types of TCM. Among them， there were 163 types of oral TCM， 25 types of TCM injection， and 53 types of other （topical） TCM. There were 3， 10 and 0 types of TCM injection， oral TCM， and other （topical） TCM with missing safety content， respectively. The main source of adverse drug reaction data for TCM injections was post- marketing monitoring data （accounting for 48.00%）； the main source of adverse drug reaction data for oral TCM was monitoring data （accounting for 71.17%）； 73.58% of other （topical） TCM did not mention the source of adverse drug reaction data. The report on national adverse drug reaction monitoring showed that the proportion of all adverse drug reactions of TCM had decreased from 17.3% in 2013 to 12.1% in 2024. Among them， the proportion of adverse drug reaction of TCM injection in the three dosage forms of TCM had decreased from 61.3% in 2015 to 24.6% in 2024， while the proportion of adverse drug reaction of oral TCM in the three dosage forms of TCM had increased from 34.7% in 2015 to 64.0% in 2024. CONCLUSIONS The risk management of TCM safety content has achieved results in China， but still faces three major challenges： strongdependence on passive monitoring， insufficient data traceability， and missing key content. It is urgent to improve safety content by dosage form， optimize data sources， and fully utilize real-world evidence to supplement safety content.

OBJECTIVE To explore and analyze the adverse drug event （ADE） signals of cinacalcet and etelcalcetide， to provide a reference for safe drug use in the clinic. METHODS ADE reports related to cinacalcet and etelcalcetide were extracted from the FDA Adverse Event Reporting System from January 1st， 2004 to June 30th， 2023 using the OpenVigil online tool. The Bayesian confidence propagation neural network method was adopted to detect the signals of ADE from the key organ systems. The signals were encoded according to the preferred term in the ADE terminology set of the Medical Dictionary for Regulatory Activities （26.0 edition）. RESULTS A total 41 709 and 1 710 ADE reports were extracted， and 29 and 45 safety signals were detected in key systems for cinacalcet and etelcalcetide， respectively； 20 and 36 positive signals were not included in the drug instructions. Hypocalcemia/decreased serum calcium， abnormal blood parathyroid hormone （PTH）/increased or decreased serum PTH were common ADEs of the two drugs， which were detected in the study. Among the signals not included in the drug instructions， new moderate and strong signals were detected， such as cinacalcet-induced calcification defense （metabolic and nutritional diseases）， bone starvation syndrome and high conversion bone diseases （musculoskeletal and connective tissue diseases） as well as etelcalcetide-induced sudden death， necrosis and treatment of non-responders （general disorders， administration site）， unstable angina pectoris， myocardial ischemia （cardiac diseases）， intestinal perforation， gastric antrum vasodilation and gastric ulcer （gastrointestinal diseases）. CONCLUSIONS In the clinical application of the two drugs， apart from the common ADEs such as hypocalcemia and abnormal blood PTH， the surveillance of some new potential ADEs should also be carried out， such as bone starvation syndrome， calcification defense， ventricular disease and other cinacalcet-induced ADEs， sudden death， myocardial ischemia， unstable angina pectoris， intestinal perforation， gastric ulcer and other etecalcetide-induced ADEs. If new ADEs appear， clinic should promptly assess the benefits and risks， and update the treatment plan and pharmacological monitoring plan to ensure the safety of patient medication.

Objective To evaluate 99mTc-HYNIC-TOC somatostatin receptor and 131 I-MIBG imaging in clinical diag-nostic of pheochromocytoma and paraganglioma(PPGL).Methods This was a retrospective study.359 PPGL pa-tients diagnosed by pathology microscopy were included.The diagnostic sensitivity and influencing factors on 99mTc-HYNIC-TOC somatostatin receptor and 131 I-MIBG imaging were analyzed.Results The positive rate of 99mTc-HYN-IC-TOC somatostatin receptor scintigraphy was 57.7%(184/319)and 131I-MIBG imaging was 83.2%(232/279).The positive rates of 99m Tc-HYNIC-TOC somatostatin receptor imaging in the adrenal glands,retroperitoneum,head and neck,heart and mediastinum,pelvis and bladder were 53.3%,62.5%,95.0%,66.7%,50.0%and 11.0%respec-tively and the positive rates of 131I-MIBG imaging were 86.7%,88.5%,45.4%,50.0%,75.0%and 33.3%respec-tively.The positive rate of the two imaging did not showed difference among patients with different genetic back-grounds(SDH,VHL,RET mutations).The median maximum diameter of tumors was 4.4(3.0,6.1)cm.and the diag-nostic sensitivity of somatostatin receptor imaging and 131 I-MIBG imaging for larger tumors(≥4.4 cm)was signifi-cantly higher than those for the smaller tumor group(＜4.4 cm)(64.0%vs.51.3%;92.3%vs.74.1%)(P＜0.01).Tumors in 19 patients(5.3%)failed to uptake neither imaging method.Conclusions This is the largest PPGL cohort in China concerning 99m Tc-HYNIC-TOC somatostatin receptor imaging and 131 I-MIBG imaging.The sensitivity of 131 I-MIBG imaging is higher than that of 99m Tc-HYNIC-TOC somatostatin receptor imaging,but for some tumors,such as head and neck paraganglioma,the latter has obvious advantages.These two imagings technol-ogies are complementary and the choice of them should depend the individual situation of patients.

Objective:To study the risk factors of venous thromboembolism(VTE)and the predictive value of the improved VTE score model to identify the risk of VTE in gynecological surgery patients.Methods:From Janu-ary 1,2020 to December 31,2022,41 patients with VTE after gynecological surgery were selected as the VTE group,and a total of 164 patients with adjacent gynecological surgeries during the same period were selected as the non-VTE group with a ratio of 1 :4.Univariate and multivariate Logistic regression analysis were used to ana-lyze the risk factors of VTE after gynecological surgery,and a modified VTE risk factor rapid assessment model(referred to as the improved VTE score model)was constructed.The receiver operating characteristic(ROC)curve was used to study the predictive value for VTE for in gynecological surgery,and compared with the Caprini score model(Caprini table for short).Results:①Multivatiate Logistic regression analysis showed that there were independent risk factors for postoperative VTE in gynecology surgery(OR＞1,P＜0.05),including age≥60 years,BMI≥28 kg/m2,malignant tumors,surgery time＞3 hours,history of thrombosis,and the increased D-di-mer difference before and after surgery.②The Area under Curve(AUC)of ROC was 0.963 in the improved VTE score model with a Youden index 81.10％,sensitivity 87.80％and specificity 93.29％.The AUC of the Caprini score model was 0.888 with Youden index 63.41％,sensitivity 73.17％and specificity 90.24％.The improved VTE score model the Caprini score model identified 92.68％and 85.37％of VTE patients as high-risk or ex-tremely high-risk,respectively,but the difference was not statistically significant(P＜0.05).Conclusions:More attention should be paid to the six independent risk factors for postoperative VTE in gynecology surgery.The two score models showed a similar identified level.However,the improved VTE score model is more simple and easier to operate,has better practicality,and has certain clinical promotion value.

Objective:To evaluate the efficacy and safety of transepithelial photorefractive keratectomy (Trans-PRK) combined with accelerated corneal cross-linking (CXL) for refractive error in patients with thin or irregular corneas, excluding keratoconus.Methods:An observational case series study was performed.Fifty-five right eyes of 55 myopic patients diagnosed with thin or irregular corneas, who underwent Trans-PRK combined with prophylactic CXL surgery, were included at Baotou Chaoju Eye Ophthalmic Hospital from August 2017 to July 2018.Uncorrected distance visual acuity (UDVA) of the operated eye was measured using international standard visual acuity charts, and refractive diopters were measured by computer and comprehensive refraction before surgery and at 1 week, 1, 3, 6, and 12 months after surgery.Corneal morphology was assessed with the Pentacam anterior segment analyzer before surgery and at 3, 6, and 12 months after surgery.Intraocular pressure (IOP) was measured with a non-contact tonometer before surgery and at 1, 3, 6, and 12 months after surgery.The incidence of postoperative complications was recorded.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of Baotou Chaoju Ophthalmic Hospital (No.btcj-u-1). Written informed consent was obtained from each subject.Results:Preoperative, 1-week, 1-, 3-, 6-, and 12-month postoperative UDVA (LogMAR) were 0.52(0.55, 0.78), 0.22(0.12, 0.17), 0.10(0.04, 0.07), 0.00(-0.04, -0.16), -0.08(-0.05, -0.03) and -0.08(-0.06, -0.04), respectively, showing a statistically significant overall difference ( Z=249.44, P<0.001). UDVA at each postoperative time point was improved compared to preoperative, and UDVA at 3, 6, and 12 months postoperatively was significantly improved compared to 1 week and 1 month postoperatively (all at P<0.001). The spherical diopter at each postoperative time point decreased significantly compared to preoperative, with the spherical diopter at 1, 3, 6, and 12 months postoperatively being lower than that at 1 week postoperatively, and the 12-month postoperative spherical diopter being lower than that at 3 and 6 months postoperatively, showing statistically significant differences (all at P<0.001). The cylindrical degree at 1, 3, 6, and 12 months postoperatively was lower than that at preoperative and 1 week postoperatively, with statistically significant differences (all at P<0.05). After the operation, the spherical equivalent of the operated eye gradually decreased with time, tending toward emmetropia.The spherical equivalent at each postoperative time point decreased compared to preoperative, with the spherical equivalent at 1, 3, 6, and 12 months postoperatively being lower than that at 1 week postoperatively, and the spherical equivalent at 12 months postoperatively being lower than that at 3 and 6 months postoperatively, showing statistically significant differences (all at P<0.001). The corneal K1 and K2 values at 3, 6, and 12 months postoperatively were significantly lower than preoperatively (all at P<0.001), and the corneal K1 and K2 values at 3 months postoperatively tended to stabilize.The IOP of the operated eye at 3, 6, and 12 months postoperatively was significantly lower than preoperatively, and the IOP at 6 and 12 months postoperatively was lower than that at 1 and 3 months postoperatively, with statistically significant differences (all at P<0.001). One eye developed grade 0.5 corneal haze at 1 week postoperatively, which spontaneously resolved to transparency at 1 month postoperatively. Conclusions:Trans-PRK combined with accelerated CXL has good efficacy, stability and safety for refractive error patients with thin or irregular corneas, except for keratoconus.
