Objective To retrospectively analyze the clinical efficacy of Xuanfei Tongqiao Acupuncture for the treatment of allergic rhinitis(AR)based on real world studies.Methods Clinical data in the hospital information system of Acupuncture and Moxibustion Rehabilitation Department of the Affiliated Hospital of Nanjing University of Chinese Medicine from January 2021 to October 2022 and Excel sheet records were extracted.The data were screened according to the criteria.Based on the thresholds of receiver operating characteristic(ROC)curve,the treatment grouping thresholds were clarified.The acupuncture patients was divided into acupuncture group A and acupuncture group B,the treatment was Xuanfei Tongqiao Acupuncture.Groups A and B were compared using propensity score matching(PSM)to make the baseline balance comparable between groups.The efficacy,total effective rate,total nasal symptom score(TNSS),total non nasal symptoms score(TNNSS),adverse events,and recurrence were then compared between the two groups.In stratified analyses,the inverse probability of treatment weighting(IPTW)method was used for between-group comparisons.The efficacy,total effective rate,TNSS and TNNSS,incidence of adverse events,and recurrence were compared between the two groups,respectively.The TNSS and TNNSS before and after treatment within the group were also compared.Results A total of 209 patients'data were collected,including 7 non-acupuncture patients and 202 acupuncture patients,and the acupuncture patients was divided into acupuncture group A(<6 weeks of treatment)and acupuncture group B(≥6 weeks of treatment)according to the ROC curve characteristics,and there was a difference in comparing the conditions of the two groups(P<0.05).66 pairs of patients were successfully matched after PSM,and there was no significant difference between the two groups at baseline(P>0.05).After PSM,the efficacy,total effective rate,post-treatment TNSS and TNNSS and TNSS at the follow-up between the two groups were compared,and the post-treatment TNSS and TNNSS within the groups were also compared,with statistical significance(P<0.01).There was statistical significance in the recurrence rate between the two groups before PSM(P<0.05),while there was no statistical significance in the incidence of adverse events before PSM and in the recurrent rate after PSM between the two groups(P>0.05).Stratified analysis was conducted on patients in the acupuncture patients based on their condition.Mild and moderate to severe patients were divided into acupuncture group A and group B according to the course of treatment.The TNSS and TNNSS before and after treatment were compared within the two groups,with statistical significance(P<0.01).IPTW was performed on two groups to ensure baseline balance and comparability,and there was statistical significance in the distribution of efficacy levels between the two groups(P<0.05),but there was no statistical significance in the total effective rate,TNSS and TNNSS scores after treatment and at follow-up,incidence of adverse events,and recurrence rate between the two groups(P>0.05).The distribution of efficacy levels,total effective rate,TNSS and TNNSS after treatment and at follow-up were compared between the two groups of moderate to severe patients,and the differences were statistically significant(P<0.01).There was no statistical significance in the incidence of adverse events and recurrence rates between the two groups(P>0.05).The TNSS and TNNSS of two groups of moderate to severe patients significantly decreased after treatment compared with before treatment(P<0.01).Conclusion Xuanfei Tongqiao Acupuncture treatment for AR with a duration of 6 weeks or more shows more significant and long-lasting clinical efficacy compared with a duration of less than 6 weeks.Especially for patients with moderate-to-severe AR,this course of treatment can better reflect the advantages of its efficacy.

Ischemic stroke has a high rate of disability and mortality and is often accompanied by white matter injury(WMI).WMI patients often have cognitive disorders,emotional disorders,sensorimotor disorders,urinary incontinence and other symptoms,which seriously affect daily life.WMI can be detected early through imaging techniques,but there is a lack of appropriate intervention and specific treatment.Studying the pathological mechanism of WMI after ischemic stroke is helpful to prevent the occurrence of WMI,delay its progression,and contribute to the development of effective drugs or specific treatments.This article reviewed the research progress of WMI mechanism after ischemic stroke in order to provide scientific basis for clinical prevention and treatment.

Objective To explore the effect and safety of magnetic resonance imaging and transrectal ultrasound (mpMRI-TRUS) image fusion targeted transperineal biopsy technique using electromagnetic needle tracking under local anesthesia. Methods We retrospectively analyzed the clinical and pathological data of 81 patients with mpMRI-TRUS image fusion targeted transperineal prostate biopsy using electromagnetic needle tracking under local anesthesia. Visual analog scale (VAS) and visual numeric scale (VNS) were used to evaluate the pain level and satisfaction of patients during prostate biopsy (VAS-1 and VNS-1), one hour after puncture (VAS-2 and VNS-2), and one day after surgery (VAS-3 and VNS-3). The perioperative clinical data and tumor positive rate of postoperative biopsy were recorded. Results The average prostate volume of 81 patients was 53.39±29.46 cm³. The PSA values of patients with PI-RADS scores of 2, 3, 4, and 5 were 9.14±2.31, 9.95±4.10, 14.77±6.36, and 32.17±24.39 ng/ml, respectively. The scores of VAS-1, VAS-2, and VAS-3 were 1.70±0.73, 1.16±0.58, and 0.53±0.55, respectively; the scores of VNS-1, VNS-2, and VNS-3 were 2.74±0.44, 3.69±0.46, and 3.84±0.37, respectively. The average surgical time was 17.47±3.44 minutes. Postoperative pathological results showed that the tumor positive rate of targeted prostate biopsy was 64.20%. According to the PI-RADS score for subgroup analysis, the tumor positive rates of patients with PI-RADS scores of 2, 3, 4, and 5 were 21.43%, 44.44%, 61.11%, and 96.77%, respectively. After transperineal prostate biopsy, gross hematuria occurred in 19.75% patients, and urinary retention occurred in 3.70%. The latter were relieved after symptomatic treatment. All patients did not experience complications, such as perineal puncture area hematoma, urinary tract infection, hematospermia, hematoma in perineal puncture area, urinary tract infection, hematospermia, vagus nerve reaction, or septic shock. Conclusion For suspected prostate cancer patients, mpMRI-TRUS image fusion targeted transperineal biopsy technique using electromagnetic needle tracking under local anesthesia is a feasible and easily tolerated surgical procedure. It has good safety and high tumor positive-detection rate, indicating that this technique is worthy of further clinical promotion and application.

A retrospective case series was used to evaluate the effect of plasmatrix bone blocks on bone augmentation at the level of the alveolar ridge. From January 2021 to April 2022, a total of 25 patients who underwent horizontal alveolar ridge level bone augmentation in the Department of Implantology, Wuhan Dazhong Stomatological Hospital were included. Autologous bone chips, deproteinized bovine bone matrix and plasma matrix were used to make plasma matrix bone blocks, combined with absorbable collagen membrane and plasma matrix membrane for guided bone regeneration. Three-dimensional reconstruction was performed on the cone beam CT data before operation and 6 months after operation, and the bone width and alveolar bone volume at 2 and 8 mm from the alveolar crest were measured. The paired t test was used to compare the differences between two time points of the same measurement item. The results showed that compared with preoperative [(5.5±3.4) mm] bone width, the bone width [(9.5±2.5) mm] at 2 mm from the alveolar crest was significantly increased at 6 months after operation ( t=3.40, P?0.001); there was no significant difference in the bone width at the level of 8 mm from the alveolar crest between pre-and 6 months post-operation ( t=3.13, P=0.050). The volumes of alveolar bone at 2 and 8 mm from the alveolar crest were (5 114±3 883) and (3 329±2 874) mm 3 before operation, respectively, and these increased significantly to (5 999±4 318) and (4 042±3 260) mm 3 ( t=5.69, P?0.001; t=5.689, P?0.001) 6 month post-operation. The results from this study has shown that the use of plasmatrix bone blocks+absorbable collagen membrane+plasma matrix membrane for horizontal bone augmentation in guided bone regeneration has a promising bone augmentation outcome.

Colorectal cancer stem cells are undifferentiated tumorigenic cells with malignant phenotypic characteristics in colorectal cancer and considered as the main cause of tumor recurrence, drug resistance, and metastasis through self-renewal and differentiated cloning. Colorectal cancer stem cells and various components in the tumor microenvironment are interdependent and influence one another. The relationship between tumor stem cells and other components in the tumor microenvironment may play an important role in the treatment of colorectal cancer. This review summarizes this relationship.

Background::Ciprofol (HSK3486; Haisco Pharmaceutical Group Co., Ltd., Chengdu, China), developed as a novel 2,6-disubstituted phenol derivative showed similar tolerability and efficacy characteristics as propofol when applicated as continuous intravenous infusion for 12 h maintenance sedation in a previous phase 1 trial. The phase 2 trial was designed to investigate the safety, efficacy, and pharmacokinetic characteristics of ciprofol for sedation of patients undergoing mechanical ventilation.Methods::In this multicenter, open label, randomized, propofol positive-controlled, phase 2 trial, 39 Chinese intensive care unit patients receiving mechanical ventilation were enrolled and randomly assigned to a ciprofol or propofol group in a 2:1 ratio. The ciprofol infusion was started with a loading infusion of 0.1-0.2 mg/kg for 0.5-5.0 min, followed by an initial maintenance infusion rate of 0.30 mg·kg -1·h -1, which could be adjusted to an infusion rate of 0.06 to 0.80 mg·kg -1·h -1, whereas for propofol the loading infusion dose was 0.5-1.0 mg/kg for 0.5-5.0 min, followed by an initial maintenance infusion rate of 1.50 mg·kg -1·h -1, which could be adjusted to 0.30-4.00 mg·kg -1·h -1 to achieve -2 to +1 Richmond Agitation-Sedation Scale sedation within 6-24 h of drug administration. Results::Of the 39 enrolled patients, 36 completed the trial. The median (min, max) of the average time to sedation compliance values for ciprofol and propofol were 60.0 (52.6, 60.0) min and 60.0 (55.2, 60.0) min, with median difference of 0.00 (95% confidence interval: 0.00, 0.00). In total, 29 (74.4%) patients comprising 18 (69.2%) in the ciprofol and 11 (84.6%) in the propofol group experienced 86 treatment emergent adverse events (TEAEs), the majority being of severity grade 1 or 2. Drug- and sedation-related TEAEs were hypotension (7.7% vs. 23.1%, P = 0.310) and sinus bradycardia (3.8% vs. 7.7%, P = 1.000) in the ciprofol and propofol groups, respectively. The plasma concentration-time curves for ciprofol and propofol were similar. Conclusions::ciprofol is comparable to propofol with good tolerance and efficacy for sedation of Chinese intensive care unit patients undergoing mechanical ventilation in the present study setting.Trial registration::ClinicalTrials.gov, NCT04147416.
