Wound healing is a complex and highly coordinated physiological process,involving the interaction of various cell types,growth factors,and extracellular matrix.Its goal is to repair damaged tissue and restore skin integrity and function.However,various internal and external factors can lead to delayed or abnormal wound healing,causing significant pain and economic burdens for patients.Therefore,it is of great clinical significance to develop safe and effective treatments to promote wound healing.In recent years,research on natural products in the field of wound healing has attracted widespread attention,and berberine,a biological alkaloid with multiple pharmacological activities,has garnered considerable attention for its remarkable effects in promoting wound healing.This article provides an in-depth review on the progress in the application of berberine in wound healing from multiple perspectives.

Objective To establish a rapid analysis method for cyanide based on a ratiometric fluores-cent probe,providing a quantitative strategy for on-site visual and rapid detection of cyanide.Methods A dual-emission ratiometric fluorescent probe(AuNCs-FL)was constructed by using bovine serum al-bumin(BSA)-stabilized gold nanoclusters(AuNCs,fluorescence emission at 660 nm)as the responsive signal unit and fluorescein(FL,emission at 515 nm)as the internal reference.Results The etching effect of cyanide on AuNCs resulted in fluorescence quenching at 660 nm,while the fluorescence inten-sity of FL at 515 nm remained unchanged,enabling a rapid response analysis of cyanide shift from red to green fluorescence.The developed probe enabled rapid analysis of cyanide within 3 min,with a limit of detection(LOD)of 3.4 mg/L and a visual detection range of 10-100 mg/L.Conclusion The AuNCs-FL fluorescent probe is structurally simple,low-cost,and easy to operate,delivering rapid and accurate results.It also avoids the interference from sulfides encountered in commercial cyanide test kits,making it suitable for the on-site rapid detection of suspected powder samples in cyanide poisoning cases.

Objective To evaluate the surgical technique and clinical value of laparoscopic bladder diverticulectomy guided by inserting ureteral catheters into the diverticulum under plasmakinetic resectoscope.Methods From December 2018 to May 2024,9 patients underwent laparoscopic bladder diverticulectomy in combination with resectoscope.Each patient had a solitary bladder diverticulum with a median maximum diameter of 6.40(5.70,7.40)cm(range:5.0～8.5 cm).Among the 9 patients,3 patients had concurrent benign prostatic hyperplasia(BPH)and simultaneously underwent transurethral plasmakinetic resection of the prostate;1 patient had concurrent both BPH and bladder calculi,requiring simultaneously underwent plasmakinetic resection of the prostate and bladder calculi removal;2 patients required ureteral reimplantation as the diverticulum was directly involving the ureteral orifice;1 case underwent ureteroscopic double-J stent implantation because the opening of the ipsilateral ureter was adjacent to the entrance of the diverticulum.Results Bladder diverticulectomy was successfully performed in the all patients.Median operative time was 160.00(120.00,317.50)min(range:85～345 min).Median estimated blood loss was 20.00(10.00,150.00)mL(range:10～300 mL).No iatrogenic injuries to adjacent organs were observed.Pelvic drains were removed 1～3 d postoperatively,with no urine leakage.Urinary catheters were maintained for 7～10 d after operation.Follow-up at 3～12 months showed no recurrence or hydronephrosis in any of the patients.Conclusion Laparoscopic resection of bladder diverticula guided by ureteral catheter placed into bladder diverticula by means of resectoscope has the advantages of less trauma,less bleeding and faster recovery,and is an effective measure for the treatment of bladder diverticula.

Objective To investigate the clinical efficacy and safety of facilitated percutaneous coronary intervention(PCI)with half-dose recombinant staphylokinase(r-SAK)in patients with ST-segment elevation myocardial infarction(STEMI)who are expected to undergo PCI within 120 minutes.Methods From October 2021 to August 2022,a total of 200 STEMI patients in eight centers were included and randomly assigned in a 1﹕1 ratio to either r-SAK group or control group.Patients received loading doses of aspirin and ticagrelor and intravenous heparin and were randomized to receive an intravenous bolus of either 5 mg r-SAK or normal saline prior to PCI.The outcomes were set as ST-segment resolution(STR)at 60-90 minutes after PCI,the proportion and transition of pathological Q waves on the 5th day after PCI,and the proportion of high-sensitivity cardiac troponin T(hs-cTnT)peaking within 12 hours of onset.The safety outcome was major bleeding events defined as Bleeding Academic Research Consortium(BARC)≥type 3 bleeding during hospitalization.Results Compared with the control group,the r-SAK group had a higher proportion of STR≥70%within 60-90 minutes after PCI(58.3%vs.40.3%,P=0.009);a lower proportion of pathological Q waves(59.1%vs.74.1%,P=0.040);a lower rate of Q wave progression(14.8%vs.43.2%,P＜0.001);a higher rate of Q wave disappearance(12.5%vs.3.7%,P=0.027);and a higher proportion of hs-cTnT peaking within 12 hours of symptom onset[31/40(77.5%)vs.17/33(51.5%),P=0.027].Regarding the safety outcome,no significant difference in BARC≥type 3 bleeding was found between the two groups during hospitalization(P＞0.05).Conclusions For STEMI patients who were expected to undergo primary PCI within 120 minutes of symptom onset,the facilitated PCI with half-dose r-SAK significantly increased the proportion of STR≥70%at 60-90 minutes after PCI,reduced the formation of pathological Q waves,and shortened the time to peak hs-cTnT,without increasing the risk of bleeding,which should be an alternative reperfusion strategy worthy of further study.

Objective In order to shorten the transparency time of clear,unobstructed brain imaging cocktails and computational analysis(CUBIC),improve the transparency efficiency,and explore the possibility of applying hydrophilic tissue transparency technique,this study was conducted to optimize the perfusion of CUBIC technique and compare it with four hydrophilic tissue clearing method in terms of tissue transparency effect,transparency time,area change,volume change and adeno-associated virus(AAV)fluorescence retention.Methods Brain,liver,spleen and kidney of 6 adult Institute of Cancer Research(ICR)mice were subjected to clearing treatment by SeeDB,FRUIT,ScaleS and CUBIC method,respectively.The area and gray value of the samples were measured by Image J 1.8.0,and the volume before and after transparency was measured by drainage method to compare the transparency effect,time and size deformation of each group.Perfusion optimization of the CUBIC was performed by improving the perfusion rate with the optimal perfusion dose,each group of the experimental sample size was 6.Fluorescence preservation by different techniques was evaluated by injecting AAV in the motor cortex of 16 adult mice and taking the cervical spinal segments for transparency treatment after four weeks,and the fluorescence photographs were measured by Image J 1.8.0 to measure the mean fluorescent intensity.Results The optimal perfusion rate and dose of CUBIC was 15 ml/min and 200 ml respectively.For transparency ability and speed,the perfusion CUBIC had the lowest mean gray value and took the shortest time,while CUBIC consumed the longest time,and SeeDB,FRUIT,and ScaleS did not show good transparency ability.In terms of area and volume changes,several techniques showed different degrees of expansion after transparency of tissues or organs.In terms of fluorescence retention,perfusion CUBIC showed the best retention of green fluorescent protein(GFP)fluorescence signal,followed by CUBIC,ScaleS,FRUIT,and SeeDB.Conclusion Perfusion CUBIC technique shows the best tissue transparency,the shortest transparency time,and the most AAV fluorescence retention compared with other techniques.

Objective To discuss the effects of polybrominated diphenyl ethers （PBDEs） exposure in e-waste dismantling region on the human body and provide data support for the identification of environmental health damage to residents in the e-waste dismantling region. Methods Adults in an e-waste dismantling region （exposed group, 54 participants） and a control region （control group, 58 participants） were selected, questionnaires were carried out and blood and urine samples were collected. Blood PBDEs, blood lipids, blood routine, blood lead, urine cadmium, urine chromium and urine nickel were detected. T-test was utilized to compare the differences of PBDEs between the two groups. Multivariate analysis were utilized to compare the differences between the two groups in blood routine indexes. Linear regression was used to analyze the relationship between PBDEs and blood routine. Results Exposure levels of PBDEs were significantly higher in the exposed group （240.00 ng/g, adjusted mass fraction of blood lipids, thereafter） than in the control group （93.00 ng/g, P<0.05）. There was no statistical significance in the differences in most blood routine indexes of the two groups （ P>0.05）, and their reference values were all within normal ranges. Mean platelet volume, plateletcrit, basophils percentage, absolute value of basophils, and mean corpuscular hemoglobin concentration were higher in the exposed group than in the control group （P<0.05）. Platelet distribution widths were lower in the exposed group than in the control group and below the normal reference range （P<0.05）. Conclusion PBDEs exposure in e-waste dismantling region tend to change platelet morphology, the number of basophils, and mean corpuscular hemoglobin concentration, and may pose potential health hazards to local residents.

Objective To investigate the impact of blood glucose level on the recurrence of liver cancer after laparoscopic surgery. Methods The clinical data of 98 patients with primary hepatocellular carcinoma from January 2012 to January 2015 were retrospectively analyzed. All patients were treated by laparoscopic radical resection of hepatocellular carcinoma. Patients were divided into elevated blood glucose group (n = 23) and control group (n = 75) according to whether the fasting blood glucose was ≥6.1 mmol/L. The recurrence of liver cancer in 1 year and 2 years after operation was compared. The factors influencing the recurrence of liver cancer were analyzed by univariate and multivariate analysis. Results The recurrence rates were 47.82% and 21.33% respectively in the patients with elevated blood glucose and the control group. The recurrence rates were 73.91% and 36.00%respectively in the 2-year postoperative patients with blood glucose and 1 year and 2 years. The recurrence rate was higher than that of the control group, the difference was statistically significant (P < 0.05). Logistic multivariate analysis showed that fasting blood glucose was high, Child-Pugh grade B, intraoperative blood transfusion, lymphatic invasion, high clinical pathology stage, postoperative alpha-fetoprotein (AFP) high, no postoperative adjuvant therapy (P < 0.05). Conclusion The recurrence rate of patients with elevated liver cancer after laparoscopic surgery is high, and fasting blood glucose is high, Child-Pugh grade is B grade, blood transfusion is high, there is lymphatic invasion, high clinical pathology stage after AFP high, no postoperative adjuvant therapy for its postoperative recurrence of risk factors, should strengthen the monitoring of high-risk patients, reduce postoperative recurrence rate.

Objective: To compare the clinical effects of transperitoneal (Tp) versus extraperitoneal (Ep) robot-assisted radical prostatectomy (RARP) in the treatment of localized prostate cancer. METHODS: We searched PubMed, EMBASE, Web of Science, EBSCO, Cochrane Library, Wanfang, CNKI, and CBM for the articles comparing the clinical effect Tp-RARP with that of Ep-RARP in the treatment of localized prostate cancer published from January 2000 to November 2016. All the articles must meet the inclusion criteria, that is, dealing with at least one of the following aspects: operation time, intraoperative blood loss, postoperative catheterization time, length of bed confinement, perioperative complications, positive surgical margins, bowel-related complications, postoperative anastomotic leakage, and postoperative urinary continence. We subjected the data obtained to statistical analysis using the RevMan5.3 software. RESULTS: Two randomized controlled trials and six case-control studies were included in this meta-analysis, involving 451 cases of Tp-RARP and 676 cases of Ep-RARP. Compared with Tp-RARP, Ep-RARP showed significantly shorter operation time (WMD = 21.39, 95% CI: 7.54－35.24, P = 0.002), shorter length of bed confinement (WMD = 0.85, 95% CI: 0.61－1.09, P <0.001), and lower rate of bowel-related complications (RR = 9.74, 95% CI: 3.26－29.07, P <0.001). However, no statistically significant differences were found between the two strategies in intraoperative blood loss (WMD = －8.12, 95% CI: －27.86－11.63, P = 0.42), postoperative catheterization time (WMD = 0.17, 95% CI: －0.55－0.21, P = 0.38), or the rates of perioperative complications (RR = 1.34, 95% CI: －0.97－1.87, P = 0.08), positive surgical margins (RR = 1.24, 95% CI: 0.95－1.61, P = 0.12), anastomotic leakage (RR = 0.98, 95% CI: 0.46－2.10, P = 0.95), urinary continence at 3 months (RR = 0.96, 95% CI: 0.91－1.00, P = 0.05) and urinary continence at 6 months (RR = 1.00, 95% CI: 0.97－1.02, P = 0.82). CONCLUSIONS Ep-RARP has the advantages of shorter operation time, shorter length of bed confinement and lower rate of bowel-related complications over Tp-RARP, and therefore may be a better option for the treatment of localized prostate cancer. However, more multi-centered randomized controlled clinical trials are needed for further evaluation of these two approaches.
