ObjectiveTo evaluate the clinical efficacy of different acupuncture-related therapies in treating postoperative pain in patients with osteoporotic vertebral compression fractures (OVCFs) after percutaneous kyphoplasty (PKP) or percutaneous vertebroplasty (PVP) using a network meta-analysis.MethodsA systematic search was conducted in PubMed, Cochrane Library, Embase, Web of Science, China National Knowledge Infrastructure, Wanfang Database, Chinese Scientific Journal Database, and Chinese Biomedical Literature Database (SinoMed) from their inception to January 15, 2025. Outcome measures included the Visual Analog Scale (VAS) score, Oswestry Disability Index (ODI) score, and overall efficacy rate. Literature screening, data extraction, and risk-of-bias assessment were independently performed by two researchers. Data analysis was conducted using Stata 17.0 software.ResultsA total of 35 randomized controlled trials involving 2860 patients were included. The data analysis revealed that, in terms of improving VAS and ODI scores, the top three effective therapies were Fu's subcutaneous needling, wrist-ankle acupuncture, and acupotomy. For the overall efficacy rates in pain treatment, the top three therapies were wrist-ankle acupuncture, warm acupuncture and moxibustion, and Fu's subcutaneous needling. Based on the combined results across the three outcome measures, Fu's subcutaneous needling was found to be the most effective in relieving pain and improving lumbar function.ConclusionFu's subcutaneous needling, wrist-ankle acupuncture, warm acupuncture and moxibustion, and acupotomy were all effective in treating postoperative pain post-PKP/PVP and improving lumbar function. However, further high-quality, large-sample studies are required to confirm these findings.

Objective To explore the high-risk factors and prevention strategies for rebleeding in patients with upper gastrointestinal hemorrhage(UGIH)treated with endoscopy,and construct a predictive model.Methods 97 patients with UGIH who experienced rebleeding after endoscopic treatment from January 2020 to December 2023 were selected as the observation group,and another 178 patients with UGIH who did not experience rebleeding after endoscopic treatment admitted during the same period were selected as the control group,both groups were followed up for 1 year after endoscopic treatment.Clinical data of the two groups was compared,the high-risk factors for rebleeding after endoscopic treatment in patients with UGIH were analyzed by multivariate Logistic regression analysis,a predictive model was constructed,and the predictive value of the model for rebleeding after endoscopic treatment in patients with UGIH was analyzed by plotting a receiver operator characteristic curve(ROC curve)to analyze.Results The proportions of patients in the observation group with liver cirrhosis,shock,endoscopic active bleeding,Forrest classification of Ia to Ib,level of blood hemoglobin≤90 g/L,and level of blood platelet≤100×109/L were 55.67%,14.43%,37.11%,62.89%,23.71%,and 23.71%,respectively,which were higher than the control group's 41.57%,2.25%,18.54%,44.38%,3.37%,and 7.87%.The level of serum D-dimer(D-D)of the observation group was higher than that of the control group,and the bleeding volume of the observation group was more than that of the control group,the prothrombin time(PT)of the observation group was longer than that of the control group(P<0.05).Multivariate Logistic regression analysis showed that:cirrhosis((O＾R)=2.423,95%CI:1.124～5.224),shock((O＾R)=6.897,95%CI:1.487～31.995),endoscopic active bleeding((O＾R)=2.604,95%CI:1.109～6.118),Forrest grading of Ia to Ib((O＾R)=2.494,95%CI:1.162～5.354),level of blood hemoglobin≤90 g/L((O＾R)=5.270,95%CI:1.797～15.442),level of blood platelet≤100×109/L((O＾R)=5.018,95%CI:1.733～14.531),bleeding volume>189.61 mL((O＾R)=1.025,95%CI:1.016～1.034),PT>15.99 s((O＾R)=1.996,95%CI:1.618～2.460)were both risk factors for rebleeding in UGIH patients after endoscopic treatment(P<0.05).Regression equation model:logit(P)=-18.551+cirrhosis×0.885+shock×1.931+endoscopic active bleeding×0.957+Forrest grading×0.914+level of blood hemoglobin×1.662+level of blood platelet×1.613+bleeding volume×0.025+PT×0.691.The ROC curve for predicting rebleeding in UGIH patients after endoscopic treatment was plotted according to the diagnostic probability logit(P).When logit(P)>0.30,the 95%CI was 0.891～0.955,and the diagnostic sensitivity and specificity were 88.66%and 83.15%,respectively.The area under the curve(AUC)value was 0.923.Conclusion The cirrhosis,shock,endoscopic active bleeding,Forrest grade Ia to Ib,level of blood hemoglobin≤90 g/L,level of blood platelet≤100×109/L,bleeding volume>189.61 mL,and PT>15.99 s are independent risk factors for rebleeding after endoscopic treatment in patients with UGIH.The model constructed based on this has high predictive value,which can be used clinically to provide personalized intervention and treatment for high-risk patients to reduce or avoid the occurrence of rebleeding.

Objective: To investigate the correlation between magnetic resonance imaging-based vertebral bone quality (VBQ) score and screw loosening after dynamic pedicle screw fixation with polyetheretherketone (PEEK) rods, and evaluate its predictive value. Methods: A retrospective analysis was conducted on the patients who underwent dynamic pedicle screw fixation with PEEK rods from March 2017 to June 2022. Data on age, sex, body mass index, hypertension, diabetes, hyperlipidemia history, long-term smoking, alcohol consumption, VBQ score, L1–4 average Hounsfield unit (HU) value, surgical fixation length, and the lowest instrumented vertebra were collected. Logistic regression analysis was employed to assess the relationship between VBQ score and pedicle screw loosening (PSL). Results: A total of 24 patients experienced PSL after surgery (20.5%). PSL group and non-PSL group showed statistical differences in age, number of fixed segments, fixation to the sacrum, L1–4 average HU value, and VBQ score (p < 0.05). The VBQ score in the PSL group was higher than that in the non-PSL group (3.56 ± 0.45 vs. 2.77 ± 0.31, p < 0.001). In logistic regression analysis, VBQ score (odds ratio, 3.425; 95% confidence interval, 1.552–8.279) were identified as independent risk factors for screw loosening. The area under the receiver operating characteristic curve for VBQ score predicting PSL was 0.819 (p < 0.05), with the optimal threshold of 3.15 (sensitivity, 83.1%; specificity, 80.5%). Conclusion The VBQ score can independently predict postoperative screw loosening in patients undergoing lumbar dynamic pedicle screw fixation with PEEK rods, and its predictive value is comparable to HU value.

"State-target medicine" is a traditional Chinese medicine （TCM） diagnosis and treatment theoretical system proposed by Academician Tong Xiaolin based on the current development of modern medicine. The active stage of gastric ulcer， as a precancerous state of gastric cancer， has a great impact on people's health. Prof. ZHOU Xuewen， a master of TCM， innovatively put forward the theory of "toxicity-heat" etiology for the active stage of gastric ulcer， which plays an important guiding role in clinical diagnosis and treatment. The article took the theoretical system of "state-target medicine" as the framework to explain the rationale， method， formula， and medicine of Prof. ZHOU Xuewen， who applied the Xiaoyong Kuidekang based on the "toxicity-heat" theory to treat the gastric ulcer in the active stage. The Chinese medical name of gastric ulcer， "gastric carbuncle"， was established， and it was believed that gastric ulcer is born due to "toxicity" and is based on "toxicity and heat". In the course of the disease， "toxicity"， "heat"， "deficiency"， and "stasis" coexisted， and its pathogenesis was divided into three phases， namely， toxicity-heat accumulation phase， toxicity-heat affecting the health phase， and weakened body resistance and strengthened toxicity phase. According to the positioning of gastric ulcer as an "internal carbuncle"， Prof. ZHOU Xuewen proposed the treatment of gastric ulcer in the active stage with "carbuncle theory" and introduced the surgical methods of "elimination"， "support"， and "tonifying" into the treatment of gastric ulcer in the active stage. Prof. ZHOU Xuewen took "clearing heat and removing toxins， eliminating carbuncle and generating muscle" as the basic treatment of the disease. For different stages of the disease， Prof. ZHOU Xuewen emphasized the use of the methods of clearing heat and removing toxins， supporting rot and muscle growth， and strengthening the spleen and harmonizing the stomach and created the representative formula for the treatment of gastric ulcer in the active stage with "carbuncle theory"， namely "Xiaoyong Kuidekang"， which could regulate state and targets.
