This paper reports a case of a patient with sleep-related painful erections treated by acupuncture combined with abdominal vibration therapy. The main symptom was repeated painful penile erections during nighttime sleep. The syndrome was differentiated as "water failing to nourish wood" and "liver qi stagnation". Acupuncture was applied at Baihui (GV20), Sishencong (EX-HN1), Guanyuan (CV4), and bilateral Neiguan (PC6), Hegu (LI4), Taichong (LR3), Taixi (KI3), Guilai (ST29), Yongquan (KI1), Yanglingquan (GB34), and Sanyinjiao (SP6). The treatment was combined with abdominal vibration therapy. Treatment was given once daily, five times per week. After the first treatment, the severity and duration of nocturnal erection pain were reduced, and sleep quality was improved. After two weeks of treatment, nocturnal erection pain persisted but became tolerable, with significantly shortened duration.

Hepatic stellate cells (HSCs) are the primary fibrogenic cells in the liver, and their activation plays a crucial role in the development and progression of hepatic fibrosis. Here, we report that retinoid X receptor-alpha (RXRα), a unique member of the nuclear receptor superfamily, is a key modulator of HSC activation and liver fibrosis. RXRα exerts its effects by modulating calcium/calmodulin-dependent protein kinase kinase β (CaMKKβ)-mediated activation of AMP-activated protein kinase-alpha (AMPKα). In addition, we demonstrate that K-80003, which binds RXRα by a unique mechanism, effectively suppresses HSC activation, proliferation, and migration, thereby inhibiting liver fibrosis in the CCl₄ and amylin liver NASH (AMLN) diet animal models. The effect is mediated by AMPKα activation, promoting mitophagy in HSCs. Mechanistically, K-80003 activates AMPKα by inducing RXRα to form condensates with CaMKKβ and AMPKα via a two-phase process. The formation of RXRα condensates is driven by its N-terminal intrinsic disorder region and requires phosphorylation by CaMKKβ. Our results reveal a crucial role of RXRα in liver fibrosis regulation through modulating mitochondrial activities in HSCs. Furthermore, they suggest that K-80003 and related RXRα modulators hold promise as therapeutic agents for fibrosis-related diseases.

OBJECTIVES: To construct vocal recognition classification models using 6 machine learning algorithms and vocal emotional characteristics of individuals with subthreshold depression to facilitate early identification of subthreshold depression. METHODS: We collected voice data from both normal individuals and participants with subthreshold depression by asking them to read specifically chosen words and texts. From each voice sample, 384-dimensional vocal emotional feature variables were extracted, including energy feature, Meir frequency cepstrum coefficient, zero cross rate feature, sound probability feature, fundamental frequency feature, difference feature. The Recursive Feature Elimination (RFE) method was employed to select voice feature variables. Classification models were then built using the machine learning algorithms Adaptive Boosting (AdaBoost), Random Forest (RF), Linear Discriminant Analysis (LDA), Logistic Regression (LR), Lasso Regression (LRLasso), and Support Vector Machine (SVM), and the performance of these models was evaluated. To assess generalization capability of the models, we used real-world speech data to evaluate the best speech recognition classification model. RESULTS: The AdaBoost, RF, and LDA models achieved high prediction accuracies of 100%, 100%, and 93.3% on word-reading speech test set, respectively. In the text-reading speech test set, the accuracies of the AdaBoost, RF, and LDA models were 90%, 80%, and 90%, respectively, while the accuracies of the other 3 models were all below 80%. On real-world word-reading and text-reading speech data, the classification models using AdaBoost and Random Forest still achieved high predictive accuracies (91.7% and 80.6% for AdaBoost and 86.1% and 77.8% for Random, respectively). CONCLUSIONS Analyzing vocal emotional characteristics allows effective identification of individuals with subthreshold depression. The AdaBoost and RF models show excellent performance for classifying subthreshold depression individuals, and may thus potentially offer valuable assistance in the clinical and research settings.

Objective To investigate the effect of CXXC finger protein 4 (CXXC4) on the proliferation and apoptosis of pancreatic cancer PANC-1 cells.Methods The expression level of CXXC4 in pancreatic canc-er tissues and its relationship with prognosis and clinicopathological stage of the patients were analyzed in on-line databases.The qRT-PCR technique was used to detect the mRNA expression level of CXXC4 in human normal pancreatic ductal epithelial cell line (HPNE) and pancreatic cancer cell PANC-1,AsPC-1 and BxPC-3. si-NC,si-CXXC4,pcDNA3.1 and pCDNA3.1-CXXC4 were respectively transfected into PANC-1 cells.West-ern blot was conducted to detect the effectiveness of CXXC4 knockdown and overexpression.CCK-8,colony formation,EdU and immunofluorescence assays were conducted to analyze the effect of CXXC4 knockdown or overexpression on the proliferation and apoptosis of PANC-1 cells.The bioinformatic websites was used to predict the upstream microRNA (miRNA) of CXXC4.The Starbase database was adopted to analyze the cor-relation between miR-450b-5p and CXXC4 expression in pancreatic cancer tissues.Results The TCGA data-base results showed that the expression of CXXC4 in pancreatic cancer tissues was lowly expressed compared with in paracancerous pancreatic tissues (P<0.001),moreover which was associated with the overall survival and poor prognosis in the patients with pancreatic cancer (P<0.05).The GEPIA database analysis results showed that compared with stage Ⅰ pancreatic cancer,the CXXC4 expression in stage Ⅱ pancreatic cancer was decreased (P<0.05).Compared with HPNE cells,the CXXC4 expression in 3 kinds of pancreatic cancer cells was decreased (P<0.05).Compared with the si-NC group,the proliferation and colony formation ability of PANC-1 cells in the si-CXXC4 group were enhanced,the expressions of proliferation markers Ki67 and PC-NA were increased,and the expressions of apoptosis markers Bax,caspase-3 and caspase-9 were decreased;compared with the pcDNA3.1 group,the PANC-1 cells in the pcDNA3.1-CXXC4 group obtained the opposite results (all P<0.05).The bioinformatic websites predicted that miR-450b-5p was the upstream miRNA of CXXC4,CXXC4 in pancreatic cancer tissues was negatively correlated with the miR-450b-5p expression (r=-0.227) and miR-450b-5p in various mammalian species was highly conserved.Conclusion CXXC4 inhibits the proliferation of PANC-1 cells in pancreatic cancer and promotes theirs apoptosis.

Objective:To establish an environmental management strategy for the prevention of ventilator-associated pneumonia from the perspective of etiological characteristics and to verify its application effect.Methods:Based on a sampling survey, this study constructed preventive management strategies for ventilator-associated pneumonia by blocking pathogen characteristics from the perspective of both colonization and infection management in patients. From July 2021 to June 2023, a non-synchronous randomized controlled study was conducted, including a control group of 59 cases and an experimental group of 57 cases from ICU of Tianjin Teda Hospital, all of them were mechanically ventilated patients. The effectiveness of the strategy was confirmed.Results:In the control group, there were 35 males and 24 females, with an average age of (46.97 ± 18.84) years. In the experimental group, there were 39 males and 18 females, with an average age of (47.49 ± 13.85) years. During the study period, there were 9 cases of ventilator-associated pneumonia (VAP) in the control group and 2 cases in the experimental group, the difference between the two groups was statistically significant (exact odds ratio=0.031). The duration of mechanical ventilation in the experimental group (122.41 ± 18.36) h, which was shorter than that in the control group (187.62 ± 18.05) h, and the difference was statistically significant ( t=19.28, P<0.05). The length of ICU stay in the experimental group was (8.38 ± 0.79) d, in the control group was (10.99 ± 1.10) d, the difference between them was statistically significant ( t=14.66, P<0.05). On the 7th day, there were 7 cases of positive pathogenic bacteria in sputum culture in the experimental group, which was significantly different from the 29 cases in the control group ( χ2=16.73, P<0.05). Conclusions:The vector management strategy for preventing ventilator-associated pneumonia by blocking etiological characteristics can reduce the incidence of VAP, shorten the duration of mechanical ventilation and ICU stay, and reduce the pathogen load in the sputum of mechanically ventilated patients on the 7th day.

Objective To explore the changes in periretinal defocus and visual quality after femtosecond laser-assis-ted in situ keratomileusis(FS-LASIK).Methods Fifty-one myopic patients(102 eyes)who underwent FS-LASIK at the Ineye Hospital of Chengdu University of Traditional Chinese Medicine from March to May 2023 were selected for the study,including 27 females(54 eyes)and 24 males(48 eyes).The defocus around the retina was measured using a multispectral refraction topography,and the total refraction difference value(TRDV)was recorded.The refraction difference value(RDV)in four quadrants:superior RDV(RDV-S),inferior RDV(RDV-I),nasal RDV(RDV-N),and temporal RDV(RDV-T),as well as the RDV in the concentric ring areas corresponding to 10°,20°,30°,40°,and 53° from the fovea of the mac-ula(represented as RDV 0°-10°,RDV 10°-20°,RDV 20°-30°,RDV 30°-40°,and RDV 40°-53°,respectively)were also re-corded.The objective scattering index(OSI),Strehls ratio(SR),modulation transfer function(MTF)values(represen-ted as 10 c·d-1 MTF,20 c·d-1 MTF,and 30 c·d-1MTF,respectively)and cutoff frequencies(MTF cutoff)at the spa-tial frequencies of 10 c·d-1,20 c·d-1 and 30 c·d-1 were measured and recorded using a visual quality analysis system.The data of corneal vertical trefoil(Z3-3),vertical coma(Z3-1),horizontal coma(Z31),horizontal trefoil(Z33),vertical tetrafoil(Z4-4),vertical secondary astigmatism(Z4-2),spherical aberration(Z40),horizontal secondary astigmatism(Z42),horizontal tetrafoil(Z44),and total higher-order aberration(HOA)were measured and recorded using the iTrace aberration meter.The measurement data of patients before surgery,one month after surgery,and three months after sur-gery were compared,and their correlations were analyzed.Results TRDV,RDV-S,RDV-N,RDV 20°-30°,RDV 30°-40°,and RDV 40°-53° around the retina of patients decreased one month and three months after surgery compared with those be-fore surgery,and the differences were statistically significant(all P＜0.001).There were statistically significant differences in OSI,MTF cutoff,and 10 c·d-1 MTF among patients before surgery,one month after surgery,and three months after surgery(all P＜0.05).There were statistically significant differences in corneal Z3-3,Z3-1,Z31,Z33,Z4-4,Z4-2,Z40,Z42,Z44,and HOA among patients before surgery,one month after surgery,and three months after surgery(all P＜0.001).The Pearson correlation analysis results showed that,ΔRDV 0°-10° was positively correlated with ΔZ3-3,ΔZ31,ΔZ4-2,ΔZ40,and ΔZ42(all P＜0.05);ΔRDV 10°-20° was positively correlated with ΔZ4-4 and ΔZ4-2(both P＜0.05);ΔRDV 20°-30° was positively correlated with ΔZ4-4 and ΔZ44(both P＜0.05);ΔTRDV and ΔRDV 40°-53° were negatively correla-ted with ΔHOA(both P＜0.05).ΔRDV-S and ΔZ3-1 were negatively correlated with ΔHOA(both P＜0.05)and positively correlated with ΔZ44(P＜0.05);ΔRDV-N was positively correlated with ΔZ4-4(P＜0.05).Conclusion FS-LASIK can reduce periretinal hyperopic defocus in myopic patients,but it introduces corneal HOA,and there is a certain correlation between the two.
