Objective To investigate differences in postoperative analgesia efficacy,inflammatory response,and recovery between intraplanar(in-plane)and extraplanar(out-of-plane)thoracic paravertebral block(TPVB)techniques under ultrasound guidance in patients undergoing thoracoscopic radical resection for lung cancer,thereby providing evidence for selecting the optimal block technique in clinical practice.Methods Eighty patients undergoing thoracoscopic radical resection for lung cancer between March and September 2022 were randomly assigned to an intraplanar group(n=40)or an extraplanar group(n=40).Before induction of anesthesia,both groups received 10 mL of 0.33％ropivacaine injected into the T4 and T6 paravertebral spaces under ultrasound guidance,using their respective in-plane or out-of-plane techniques.The following parameters were compared between the groups:nerve block procedure duration,onset time of block,visual analogue scale(VAS)pain scores within 48 hours postoperatively,incidence of postoperative nausea and vomiting(PONV),and serum inflammatory and stress markers including C-reactive protein(CRP),interleukin-6(IL-6),cortisol(Cor),and norepinephrine(NE).Results No significant differences were observed between the groups in block procedure duration,onset time,or analgesic duration(P＞0.05).Compared with the extraplanar group,the intraplanar group demonstrated a significantly reduced incidence of PONV(15.0％vs.35.0％,P=0.039)and significantly lower serum levels of CRP,IL-6,and Cor at 24 hours postoperatively(P＜0.05).No pleural punctures occurred in the intraplanar group(0％),whereas the extraplanar group had a 15.0％incidence rate.However,the overall complication rate in both groups showed no statistically significant difference(P=0.060).Conclusion Both ultrasound-guided in-plane and out-of-plane TPVB techniques provide effective postoperative analgesia for thoracoscopic radical lung cancer surgery.However,the in-plane technique significantly reduces the incidence of PONV and postoperative inflammatory responses while demonstrating higher operational safety,making it the preferred clinical choice.

OBJECTIVE To provide direction and reference for the adjustment of the discount rate （DR） in China’s pharmacoeconomic guidelines. METHODS Search was conducted on the official websites of the International Society for Pharmacoeconomics and Outcomes Research， health technology assessment agencies in various countries/regions， as well as relevant websites of other upper-middle-income or high-income countries/regions. The recommended DR， adjustment trends， and setting rationales in pharmacoeconomic evaluation guidelines across different countries/regions were then summarized and compared. Based on theoretical derivation and literature analysis， the effects of different DR on the incremental cost-effectiveness ratio （ICER） were examined. RESULTS & CONCLUSIONS Among the 40 included guidelines， the base-case DR ranged from 1.5% to 5%， with 5% being the most common value； the range for sensitivity analysis was 0 to 12%. Thirty-six countries/regions applied the same DR to both costs and health outcomes， while in the Netherlands， Belgium， Poland and Czech Republic， DR for costs was higher than for health outcomes. In recent years， Korea， France and Ireland had lowered their DR in response to economic changes， whereas the Netherlands and Czech Republic had raised their DR for cost. The setting of the DR was primarily based on the public project investment interest rate or referred to recommendations from internationally authoritative institutions and other relevant guidelines. The direction and magnitude of the impact of different DR on the ICER largely depended on the distribution of costs and health outcomes between the intervention and reference measure. The setting and adjustment of DR were closely associated with the economic environment. Based on international experience, the DR in China can be lowered by 0.5% to 1.5%， and localized empirical research can be conducted using internationally common estimation methods.

Traumatic main bronchus rupture is a relatively rare injury in thoracic trauma, which is extremely critical, with a mortality rate as high as 70% - 80%. The complete rupture and displacement of the traumatic cervical trachea can lead to asphyxia, hypoxia, and cardiac arrest, even death of the patient in a short time. We performed emergency surgery with the support of extracorporeal membrane oxygenation for a case of traumatic cervical tracheal trunk complete rupture and displacement combined with cardiac arrest and achieved a successful rescue. We summarized our experience and found that timely surgical reconstruction of the airway is the key to increasing the traumatic main bronchus rupture survival of patients.

Objective To analysis the correlations of cataract patients'age,axial length(AL)with anterior chamber depth(ACD),lens thickness(LT),and postoperative effective lens position(ELP).Methods A retrospective study was employed to analyze the biometric parameters of 7458 cataract patients(7458 eyes)who underwent surgical treatment in the First Affiliated Hospital of Kunming Medical University from January 2016 to December 2022.All measurements were obtained using the Lenstar LS900 optical biometer via optical low-coherence reflectance technology.Pearson or Spearman correlation analyses was performed between patients'age,sex,and AL with ACD,LT,and postoperative ELP measurements.Results The mean AL of patients was 23.41(22.68,24.31)mm,categorized into 4 groups:short AL group(AL≤22 mm,593 cases,8.0%),normal AL group(AL 22-24 mm,4520 cases,60.5%),longer AL group(AL 24-26 mm,1579 cases,21.2%),and long AL group(AL>26 mm,766 cases,10.3%).The ACD was(2.65±0.43)mm,and the LT was(4.29±0.46)mm.Compared with female patients,male patients had significantly longer AL,deeper ACD,and thicker LT(P<0.001).Postoperative ELPs,measured in 209 eyes 3 months after surgery,was 5.03(4.57,5.21)mm.Correlation analysis revealed a positive correlation between AL and ACD in short,normal,and longer AL groups(ρ=0.155,ρ=0.311,ρ=0.074,P<0.001 or P<0.05),while a negative correlation was found in the long AL group(ρ=-0.089,P<0.05).No statistically significant correlation was observed between AL and LT in short AL group(P>0.05),but a negative correlation was noted in normal and longer AL groups(ρ=-0.104,ρ=-0.095,P<0.001),and a positive correlation in long AL group(ρ=0.165,P<0.001).In short,normal,and longer AL groups,postoperative ELP was positively correlated with preoperative ACD(ρ=1.000,ρ=0.826,ρ=0.441,P<0.001),with no significant correlation in long AL group(P>0.05).Conclusions In cataract patients,AL,ACD,and LT are associated with both age and sex.LT and AL significantly influence ACD,while ACD and AL significantly influence LT.Preoperative ACD is the primary factor affecting postoperative ELP.

Objective To investigate the correlation of corneal α angle and κ angle with lens tilt in normal human eyes using a new swept-source optical biometer.Methods A cross-sectional study was conducted,involving 303 healthy eyes(148 right eyes and 155 left eyes)of patients who visited the First Affiliated Hospital of Kunming Medical University from June to August 2024.ZW-30 swept-source optical biometer was used to collect the lens tilt angle,κ angle(distance from the corneal light reflex to the pupil center),and α angle(distance from corneal light reflex to the corneal geometric center,which is the midpoint of the horizontal white to white(WTW)diameter).The degrees(°)and directions of κ angle and α angle were calculated by the ratio of the above measurements to the anterior chamber depth(ACD)respectively.Spearman correlation analysis and linear regression analysis were employed to evaluate the correlations between the magnitude and direction of corneal α angle,κ angle and lens tilt angle.Results The magnitude and direction of corneal α angle,κ angle,and lens tilt angle in the right eye were as follows respectively:(0.54±0.19)mm(7.81°±3.88°),194.43°±39.75°;(0.27±0.23)mm(4.72°±3.90°),181.07°±79.59°;5.52°±1.67°,188.21°±25.73°.For the left eye,the corresponding values were:(0.47±0.27)mm(8.12°±5.26°),336.04°±46.64°;(0.26±0.27)mm(4.45°±4.80°),322.86°±107.79°;5.50°±1.61°,340.65°±32.84°.Spearman's correlation analysis showed that the correlation coefficients between corneal α angle and lens tilt angle in the right eye were 0.609(distance correlation)and 0.625(angle correlation),while those for κ angle were 0.559(distance correlation)and 0.578(angle correlation).In the left eye,the correlation coefficients between corneal α angle and lens tilt angle were 0.545(distance correlation)and 0.552(angle correlation),and those for κ angle were 0.377(distance correlation)and 0.395(angle correlation).In addition,the correlation coefficient between the direction of corneal α angle and the direction of lens tilt angle in the right eye was 0.343,and that for κ angle direction was 0.284;in the left eye,the correlation coefficients were 0.216(α angle direction)and 0.198(κ angle direction),all with statistical significance(P<0.05).Univariate linear regression analysis showed that lens tilt was positively correlated with both corneal α angle and Kappa angle(P<0.05).Conclusions Corneal α angle and κ angle are highly correlated with lens tilt angle in both eyes,and the correlation of corneal α angle is stronger than that of κ angle in both left and right eyes.The correlation expressed by degree(°)is better than that by distance(mm).It is recommended to refer to the corneal α angle and κ angle expressed in degrees during preoperative evaluation.

Integrins are transmembrane receptors that can coordinate signal transduction between cells and extracellular matrix or between cells.The abnormal function of integrins is one of the recognized mechanisms of tumor development.As an important regulatory mode,post-translational modification can change the conformation and physicochemical properties of proteins,thus affecting their activities,stability and functions.After the modification of the integrin,such as glycosylation and methylation,the corresponding signal transduction pathway changes,and then affects cell adhesion,migration,differentiation and other life activities,involving in diverse physiology and pathological processes.Post-translational modifications of integrins are abundant in tumor progression and play a key role in regulating the growth,metastasis and drug resistance of different tumor cells.In this review,the structure and function,post-translational modification of integrins,and their relationship with occurrence and development of tumors will be discussed,in order to provide more explorable targets for the treatment of cancer.
