Human sperm quality was evaluated by computer assisted semen analysis (CASA) and the sperm move high test. Results The co-cultured Bushengyijing Fang medicated serum significantly increased the sperm motion velocity (VAP, VCL, VSL) (P

0 05).buprenorphine buccal produced less nausea and vomiting than those in the other route(P0 05).The changes of the vital signs in two groups were not clinically important. Conclusions The study indicates that the analgesia effects of buprenorphine sublingual administered is same as intramuscular buprenorphine,but the buprenorphine buccal is more convenient.However,the drug dependence terdency should be monitored.

The incidence of candidiasis caused by Candida albicans has increased dramatically in recent years. With the widespread use of antifungal agents, the emergence of drug resistant strains pose a major challenge to drug treatment. The overexpression of membrane proteins functioning as drug efflux pumps is one of the main mechanisms for multidrug resistance of Candida albicans. Membrane transporters associated with drug resistance in Candida albicans are reviewed in this article.

Cap1p, encoded by CAP1, is a basic region-leucine zipper (bZip) transcription factor in Candida albicans. It has been proven to play important roles in both drug resistance and oxidative stress. Within the AP-1 family, Cap1p belongs to the same subgroup which also includes Yap1p, Yap2p, and Pap1p. The function of Cap1p is regulated by a nuclear localization mechanism. In recent years, some target genes of Cap1p have been discovered and the differences as well as similarities between Cap1p and Yap1p have been revealed. However, the role of Cap1p in the drug resistance of Candida albicans still needs to be further investigated. Currently drug resistance and oxidative stress are the 2 focuses in the research of fungal pathogens, making Cap1p very important in the future study. The authors have been involved in Cap1p research for a long time and this review introduces the current progress in the area.

Background Small incision lenticule extraction (SMILE) is increasingly applied in the correction of myopia and astigmatism.However,the early clinical outcomes of SMILE for different refractive myopia and astigmatism is seldom reported.Objective This study was to investigate the safety,efficacy,predictability and early stability after SMILE in low,moderate and high myopia.Methods A series of cases-observational study was carried out.A total of 195 eyes of 108 myopic patients were enrolled in Tianjin Eye Hospital from May to December 2012 under the informed consent.The patients were divided into the low (≤-3.00 D),moderate (＞-3.00 to-6.00 D) and high myopia (＞-6.00 D) groups according to different diopters,with 57 eyes,76 eyes and 62 eyes,respectively.SMILE was performed on all the eyes.The uncorrected visual acuity (UCVA)(LogMAR),best corrected visual acuity (BCVA) (LogMAR),equivalent sphere (SE),intraocular pressure,anterior segment and corneal topography were examined before operation and 1 day,1 week,1 month and 3 months after operation to evaluate the effective index (postoperative UCVA/preoperative BCVA),safety index (postoperative BCVA/preoperative BCVA),predictability and early stability of SMILE.The linear regression analysis was used to analyze the relationships between the attempted refraction and the achieved refraction postoperative 3 months in three groups.Results The percentage of UCVA (LogMAR)＜0.1 was 100％,97.1％ and 92.8％ in the low,moderate and high myopia group,respectively in 3 months after SMILE.The postoperative BCVA of all the operated eyes reached preoperative one.The residual SE was (-0.07±0.16),(-0.05 ±0.20) and (-0.08±0.27)D in the low,moderate and high myopia group,respectively in 3 months after SMILE.The percentage of residual SE±0.5 D was 100％,98.7％ and 93.6％ in the low,moderate and high group,and that of SE±1.0 D was 100％ in all of the groups.The postoperative corrected SE was gradually increased with the raise of predicted SE in the low,moderate and high myopia groups (r=0.942,0.959,0.957,all at P＜0.001).Conclusions SMILE is safe,effective,predictable and stable for the correction of low,moderate and high myopia.The corneal wound healing was slightly slower in the low myopia group than that in the moderate and high group.A slight regression of myopic power appears in high myopia eyes 3 months after SMILE.

Background The relationship between corneal central thickness (CCT) and corneal biomechanical property does not reflect the effective amount of ablated tissue because CCT measures only the change in a single point.Corneal volume (CV) is a representative parameter of corneal morphology,and it can fully reflect corneal thickness and tissue distribution.Objective This study was to investigate the correlation between volumetric corneal changes and corneal biomechanical properties after small incision lenticule extraction (SMILE).Methods A prospective series cases-observational study was carried out.This study protocol was approved by Ethic Committee of Tianjin Eye Hospital,and written informed consent was obtained from each patient prior to entering the cohort.Sixty-seven right eyes of 67 myopia or myopic astigmatism patients who received SMILE in Tianjin Eye Hospital from June 2014 to July 2015 were included in this study.Before and 3 months after surgery,the CV at 3,3-5,5-7 and 7-10 mm (CV3,CV3-5,CV5-7,CV7-10) was measured by Pentacam anterior segment analysis system,and corneal hysteresis (CH) and corneal resistance factor (CRF) were obtained by ocular response analyzer (ORA).The changes of CV (ACV),CH (ACH) and CRF (ACRF) were calculated,and the correlations between ACV and ACH or ACRF were analyzed.Results CV3,CV3-5 and CV5-7 values after SMILE were significantly lower than those before SMILE (t =36.24,20.38,16.17,all at P＜ 0.001).The CH values before and after SMILE were (10.06± 1.11) mmHg and (8.10± 1.05) mmHg (1 mmHg =0.133 kPa),and the CRF values before and after SMILE were (10.40 ± 1.38) mmHg and (6.91 ± 1.19) mmHg,respectively,showing significant reduces after SMILE than before SMILE (t =16.71,27.41,both at P＜0.001).Positive correlations were seen between the CV values at different corneal areas and CH value or CRF value.Moderate positive correlations were found between CV3 and CH or CRF (r =0.571,0.569;both at P＜0.001) before surgery,and 3 months after surgery,a weak positive correlation was seen between ACV3 and ACH (r =0.394,P ＜ 0.001) or a moderate positive correlation between ACV3 and ACRF (r=0.501,P＜0.001).Conclusions The CV value is gradually increased from the central cornea to periphery cornea.The CV change is associated with CH and CRF changes after SMILE,and CV3 probably is a useful parameter for the evaluation of corneal biomechanics after refractive surgery.

Objective To investigate the correlations between corneal biomechanical properties and corneal high-order aberrations (HOAs) in myopic eyes.Methods In this retrospective study,263 right eyes with myopia or myopic astigmatism were enrolled from January to October 2015 in Tianjin Eye Hospital.The values of first applanation time (A1T),first applanation length (A1L),first applanation velocity (A1V),second applanation time (A2T),second applanation length (A2L),second applanation velocity (A2V),highest concavity time (HCT),highest concavity deformation amplitude (HCDA),highest concavity peak distance (HCPD),highest concavity radius (HCR) and non-contact intraocular pressure (IOPnct) were measured using the corneal visualization Scheimpflug technology (Corvis ST).The central corneal thickness (CCT) and wavefront aberrations of the anterior,posterior surface,and the total cornea were measured with Pentacam.Pearson correlation and stepwise multivariate linear regression analysis were applied to analyze the correlations between biomechanical properties and corneal HOAs.This study follows the Helsinki declaration.The experiment was approved by the Ethic Committee of Tianjin Eye Hospital.Informed consent was signed from each patient.Results There was a correlation between biomechanical properties and corneal HOAs.Negative correlations were found between A1L and the spherical aberration,HOAs RMS of anterior surface,total RMS and HOAs RMS of the posterior surface and HOAs RMS of the total cornea (P＜0.05).HCRs were negatively correlated with total RMS of the total cornea and the anterior surface (P＜0.05).The A2V was correlated with various aberrations.Multiple stepwise linear regression model analysis showed that,the correlation between the aberrations of anterior surface and biomechanical parameters,and the correlations between the total corneal aberration and biomechanical parameters were weak,the correlations between the aberrations of posterior surface and biomechanical parameters were strong.Conclusions There is a correlation between the biomechanical properties and corneal HOAs.The changes of the corneal biomechanical properties are mainly associated with the posterior corneal aberrations,which may contribute to the early diagnosis of subclinical keratoconus or dilated corneal disease.

Objective By combining biological detection and imaging evaluation, a clinical prediction model is constructed based on a large cohort to improve the accuracy of distinguishing between benign and malignant pulmonary nodules. Methods A retrospective analysis was conducted on the clinical data of the 32 627 patients with pulmonary nodules who underwent chest CT and testing for 7 types of lung cancer-related serum autoantibodies (7-AABs) at our hospital from January 2020 to April 2024. The univariate and multivariate logistic regression models were performed to screen independent risk factors for benign and malignant pulmonary nodules, based on which a nomogram model was established. The performance of the model was evaluated using receiver operating characteristic (ROC) curves, calibration curves, and decision curve analysis (DCA). Results A total of 1 017 patients with pulmonary nodules were included in the study. The training set consisted of 712 patients, including 291 males and 421 females, with a mean age of (58±12) years. The validation set included 305 patients, comprising 129 males and 176 females, with a mean age of (58±13) years. Univariate ROC curve analysis indicated that the combination of CT and 7-AABs testing achieved the highest area under the curve (AUC) value (0.794), surpassing the diagnostic efficacy of CT alone (AUC=0.667) or 7-AABs alone (AUC=0.514). Multivariate logistic regression analysis showed that radiological nodule diameter, nodule nature, and CT combined with 7-AABs detection were independent predictors, which were used to construct a nomogram prediction model. The AUC values for this model were 0.826 and 0.862 in the training and validation sets, respectively, demonstrating excellent performance in DCA. Conclusion The combination of 7-AABs with CT significantly enhances the accuracy of distinguishing between benign and malignant pulmonary nodules. The developed predictive model provides strong support for clinical decision-making and contributes to achieving precise diagnosis and treatment of pulmonary nodules.
