Objective To investigate the perioperative outcomes and postoperative pregnancy outcomes of patients with intrauterine adhesions(IUA)treated by see-and-treat hysteroscopy and traditional hysteroscopy in transcervical resection of adhesions(TCRA).Methods A retrospective cohort study was performed on 485 patients with moderate-to-severe IUA who met the inclusion criteria and admitted in our hospital from January 2019 to December 2021.According to surgical approaches,the patients were assigned into a see-and-treat mode group and a traditional mode group.After clinical diagnosis(ultrasound and symptoms)of IUA,the patients from the former group received direct hysteroscopic adhesion separation surgery,and those of the latter group were diagnosed by outpatient hysteroscopy first and then hysteroscopic adhesion separation surgery.The perioperative indicators,postoperative three-dimensional transvaginal ultrasound(3D-TVUS)examination related characteristics,postoperative menstrual recovery,postoperative pregnancy outcomes,obstetric related complications,and neonatal outcomes were collected and compared between the 2 groups.Results Among the enrolled 485 patients,there were 277 in the see-and-treat group and 208 in the traditional group.The success rate of surgical treatment was 89.89%in the see-and-treat group and 92.79%in the traditional group,but no statistical difference was seen between them(Chi-square=1.234,P=0.267).3D-TVUS examination displayed that the see-and-treat mode group obtained better improvement of endometrial morphology,uterine morphology and menstruation after operation than the traditional group(P<0.001).The postoperative pregnancy rate was slightly higher in the see-and-treat group than the traditional mode group(58.84%vs 58.17%,P=0.882).However,the see-and-treat mode showed obvious advantage in the postoperative natural pregnancy rate,with a rate of 90.80%,obviously higher than that in the traditional mode group(81.82%,P=0.026).The live birth rate was 70.55%in the see-and-treat mode group,excluding 1 case with ongoing pregnancy in the second trimester and 1 case with ongoing pregnancy in the third trimester,and the rate was 74.38%in the traditional group,excluding 3 cases with ongoing pregnancy in the third trimester,but there was no statistical difference between the 2 groups(P=0.303).In terms of obstetric-related complications,there were 0 cases of blood transfusion during delivery hospitalization in the see-and-treat group,while there were 7 cases in the traditional group(P=0.003).In neonatal outcomes,the rate of transfer to the pediatric department was 10.43%in the see-and-treat mode group and 22.22%in the traditional mode group(P=0.021).For health economics,the see-and-treat hysteroscopy group demonstrated a significant advantage over the traditional hysteroscopy group(P<0.001).There was no significant difference in pain scores between the 2 groups.Conclusion The see-and-treat approach is a safe,feasible,and highly efficient strategy for integrating the diagnosis and treatment of IUA,enabling maximal minimization of surgical trauma while optimizing time and cost efficiency.

Objectives:This study aims to investigate the expression changes of transient receptor potential vanilloid type 1 (TRPV1) channel and inflammatory factors in the peripheral blood of patients with schizophrenia, and to evaluate their potential value for diagnostic prediction.Methods:This cross-sectional study was conducted at Renmin Hospital of Wuhan University from September 2023 to June 2024. A total of 35 patients with schizophrenia (patient group) from the outpatient/inpatient departments and 35 age-and sex-matched healthy individuals (control group) were recruited. Psychiatric symptoms and cognitive function were evaluated using the Positive and Negative Syndrome Scale (PANSS) and the Brief Assessment of Cognition in Schizophrenia (BACS), respectively. The between-group comparisons of the total scores of these two instruments were calculated using independent samples t-tests. Fasting peripheral blood samples were collected from all participants. Plasma and peripheral blood mononuclear cells (PBMCs) were isolated for subsequent analysis. TRPV1 protein expression was quantified by Western blotting, while inflammatory cytokines, including tumor necrosis factor-α (TNF-α), interleukin-2 (IL-2), interleukin-4 (IL-4), interleukin-6 (IL-6), and interleukin-10 (IL-10), were measured using enzyme-linked immunosorbent assay (ELISA). The between-group differences in TRPV1 and inflammatory cytokines were analyzed using the analysis of covariance (ANCOVA), controlling for age and sex. Pearson correlation analysis was employed to examine relationships between continuous variables, controlling for years of education, age, and sex. The diagnostic performance of TRPV1 and inflammatory cytokines for schizophrenia was assessed using receiver operating characteristic (ROC) curve analysis. Results:Significant between-group differences were observed in BACS total and subscale scores ( t=2.57-9.72, all P<0.01). Compared with the control group, the patient group exhibits significantly decreased expression of TRPV1, IL-4, and IL-10 ( t=6.78, 2.75, 2.53, all P<0.01), increased expression of TNF-α, IL-2, and IL-6 ( t=4.08, 2.64, 2.63, all P<0.01), and an increased IL-6/IL-10 ratio ( t=3.18, P<0.01). Correlation analyses revealed that in the patient group, the TRPV1 expression level was negatively correlated with levels of TNF-α and IL-6, and positively correlated with levels of IL-4 and IL-10 ( r=-0.589, -0.234, 0.341, 0.293, all P<0.05). In the patient group, the TRPV1 expression level was negatively correlated with the negative symptom score of PANSS ( r=-0.299, P<0.05), and the IL-6 level was positively correlated with the negative symptom score, the general pathology score, and the total score of PANSS ( r=0.387, 0.356, 0.321, all P<0.05). The TRPV1 level was positively correlated with the total score of BACS in both the control group and the patient group ( r=0.144, 0.828, all P<0.01). The IL-6/IL-10 ratio was positively correlated with the total score of PANSS and negatively correlated with the total score of BACS in the patient group ( r=0.623, -0.333, all P<0.05). The area under the ROC curve for the combination of TRPV1 level and IL-6/IL-10 ratio was 0.98 (95% confidence interval=0.96 to 1.00). Conclusions:Patients with schizophrenia exhibit reduced expression levels of TRPV1 along with an imbalanced inflammatory response. The combined assessment of TRPV1 level and IL-6/IL-10 ratio has demonstrated a high predictive and diagnostic value for schizophrenia.

Objective:To investigate the application effect of medical failure modes and effects analysis(FMEA)in reducing the inci-dence rate of catheter dislodgement in patients in the post-anesthesia care unit(PACU).Methods:A retrospective study was con-ducted among 469 PACU patients in our hospital from January 2023 to June 2024.According to the application time of FMEA,the pa-tients were divided into routine group(234 PACU patients who did not receive FMEA from January to June 2023)and FMEA group(235 PACU patients who received FMEA from July 2023 to June 2024).The two groups were compared in terms of the incidence rate of catheter dislodgement,risk priority number(RPN)coefficients(including professional knowledge,risk awareness,and intervention guidance),the quality of recovery of consciousness(including the time to complete recovery of consciousness and the length of stay in the PACU),and the degree of satisfaction with nursing(including risk management,nursing services,and nursing techniques).Results:The FMEA group had a significantly lower incidence rate of catheter dislodgement than the routine group[0.43%(1/235)vs.2.99%(7/234),the difference was statistically significant(χ2=4.604,P=0.032)].Compared with the routine group,the FMEA group had significantly lower RPN coefficients of risk awareness t=52.518,professional knowledge t=49.641,and intervention guidancet=61.592(P<0.001).Compared with the routine group,the FMEA group had significantly shorter time to complete recovery t=18.087 of consciousness and length of stay in the PACUt=15.710(P<0.001).The FMEA group had a significantly higher degree of satisfaction with nursing than the routine group in terms of risk management t=19.794,nursing services t=10.825,and nursing techniques t=14.555(P<0.001).Conclusion:The application of FMEA manage-ment in PACU patients can reduce the incidence rates of catheter dislodgement and risk events and improve the quality of recovery of consciousness and the degree of satisfaction with nursing,and there-fore,it has important clinical significance.

Objective:To explore the feasibility of autosegmentation and reconstruction of interstitial needles in intracavitary / interstitial brachytherapy (IC-ISBT) for cervical cancer based on deep learning.Methods:The data of 180 treatment plans from 98 patients who received IC-ISBT were retrospectively collected and divided into the training, validation, and testing sets in a 16:1:1 ratio. Masks of needles were created using the dwell positions of radiation sources, and a 3D U-Net model was trained. The performance of the model was evaluated using the Dice similarity coefficient (DSC). Absolute and relative accuracy rates were used to assess the results of this method, and the position bias was used to evaluate the precision of predictions in the transversal plan of CT scans. Wilcoxon rank-sum test was performed to evaluate the reconstruction efficiency by comparing the time required for automated versus manual reconstruction.Results:DSC of the model was 0.93 ± 0.02. The absolute and relative accuracy rates were 0.44 ± 0.09 and 0.95 ± 0.03, respectively. The distance deviation on the CT horizontal plane was (0.58 ± 0.54) mm. The average time of autosegmentation and reconstruction was (6.2 ± 0.4) s, leading to a significant reduction in time consumption compared with manual construction ( P<0.001). Conclusions:Based on deep learning, using the dwell positions of radiation sources for data annotation, combined with post-processing algorithms, accurate automated segmentation and digital reconstruction of needles in IC-ISBT three-dimensional CT images can be achieved, significantly improving reconstruction efficiency.

Objective:To compare the differences in prefrontal activation patterns between major depressive disorder and schizophrenia during the eye basic emotion discrimination task (EBEDT).Methods:Using functional near infrared spectroscopy (fNIRS) technology and block design, the changes of prefrontal lobe oxyhemoglobin (Oxy-Hb) concentrations under EBEDT in 40 patients with major depressive disorder, 47 patients with schizophrenia and 55 normal controls were compared. Subsequently, employing years of education as a covariate, an analysis of covariance was performed on the EBEDT behavioral results and the changes in prefrontal Oxy-Hb concentrations in the three groups.The statistical software was SPSS 25.0.Results:(1)The correct number of EBEDT in schizophrenia group (13.93±7.67) was significantly lower than that in major depressive disorder group (19.26±8.07) and normal control group (21.79±6.36)(both P<0.05), and the EBEDT reaction time in schizophrenia group ((3.97±1.77) s) was significantly longer than those in major depressive disorder group ((3.21±1.27) s) and normal control group ((2.63±0.62) s)(both P<0.05).(2)During the EBEDT task block, the normal control group showed increased activation levels in the frontal polar region, Broca's area, anterior motor cortex and supplementary motor area (SMA) compared with the control block( t=2.02-3.18, all P<0.05); and the schizophrenia group showed increased activation levels in the frontal eye field compared with the control block( t=2.26, P=0.03); while the major depressive disorder group exhibited decreased activation levels in the entire prefrontal lobe compared with the control block( t=-3.47--2.34, all P<0.05). (3)During the emotion recognition task of EBEDT, the activation levels of the frontal polar area (ch37), dorsolateral prefrontal cortex (ch31), Broca's area (ch49, ch51, ch53), and SMA (ch1, ch47, ch52) were significantly different among the major depressive disorder, schizophrenia and normal controls( F=3.23-5.53, all P<0.05). Further pairwise comparisons showed that the activation levels in all the above pathways were lower in the major depressive disorder group than those in the normal control group, and the activation levels in Broca's area (ch53) and SMA area (ch52) were lower in the schizophrenia group than those in the normal control group, while the activation levels in the frontal polar area (ch37) and Broca's area (ch49) were lower in the major depressive disorder group than those in the schizophrenia group(all P<0.05). Conclusions:In EBEDT, the activation patterns of the prefrontal cortex are different between patients with major depressive disorder and patients with schizophrenia. Patients with major depressive disorder have a decrease in prefrontal cortex activation, while patients with schizophrenia have an increase in the frontal eye field activation.The activation levels in prefrontal cortex of both patients group are lower than that of normal controls. Meanwhile, the prefrontal cortex activation level of patients with major depressive disorder is lower than that of patients with schizophrenia.

Retinoblastoma (RB), the most common primary intraocular malignancy in infants and young children, poses a serious threat to visual function and the life of children when systemic metastasis occurs. Circular RNA (circRNA) is a recently discovered class of non-coding RNA that mainly functions as competitive endogenous RNA by regulating gene expression through competing with microRNA. circRNA can function as oncogenes or tumor suppressors, regulating various biological processes in RB cells, such as proliferation, migration, apoptosis, autophagy, and drug resistance, thereby providing new therapeutic targets for RB. In addition, the differential expression of circRNA in tumor tissues or exosomes is expected to be a potential biomarker for RB. Further studies and explorations are still needed for the functions and regulatory mechanisms of circRNA in RB to reveal their precise roles in organisms and potential clinical applications.

The pattern differentiation method is the most representative part of the inheritance of the experience of renowned practitioners of traditional Chinese medicine,reflecting their clinical thinking characteristics. Among them,Professor LYU Renhe proposed and developed the theory of abdominal masses in the long-term diagnosis and treatment of kidney diseases. Based on his clinical experience,he formed the method of differentiation of Shenluozhengjia (tangible or intangible abdominal masses of kidney collaterals). This differentiation method is characterized by its simple and easy clinical application. Tangible or intangible abdominal masses of kidney collaterals refer to chronic kidney disease,which is based on the basic cause of kidney deficiency. External or internal pathogenic factors cannot be eliminated,and prolonged illness invades the kidney collaterals,causing pathological products,such as qi stagnation,blood stasis,phlegm dampness,heat toxin,and turbid toxin to stagnate in the kidney collaterals,resulting in damage to the kidney body and loss of kidney function. The basic pathogenesis is a deficiency of kidney qi and the formation of tangible or intangible abdominal masses of the kidney collaterals. During pattern differentiation,the type is determined by the deficiency,which is fixed,and the pattern is determined by the excess,which is constantly changing with the condition and can be combined. Furthermore,he summarized the dietary principles as having more essence and less coarseness,more milk and less meat,a phased diet,and the selection of the symptomatic diet. To inherit and improve the theory and clinical practice of the pattern differentiation theory of tangible or intangible abdominal masses of kidney collaterals,this article reviews and summarizes the unique pattern differentiation method of the kidney collateral pattern from the aspects of definition,theoretical origin,etiology and pathogenesis,differentiation and treatment,and regulation,providing a basis for forming suitable diagnosis and treatment method for clinical promotion.
