ObjectiveTo develop and validate a diagnostic prediction model for differentiating pulmonary tuberculosis from community-acquired pneumonia based on routine blood parameters. MethodsA total of 642 patients with pulmonary tuberculosis and 503 patients with community-acquired pneumonia were retrospectively enrolled from the Seventh Hospital of Tangshan. They were randomly divided into a training set and an internal validation set at a 7∶3 ratio. Additionally, 218 patients from the 981st Hospital were independently included as an external validation set. The Boruta algorithm and recursive feature elimination were employed to select predictors from 82 blood parameters, sex, and age. A multivariate Logistic regression model was established and evaluated using receiver operating characteristic (ROC) curves, calibration curves, and decision curve analysis. ResultsThe final model incorporated eight predictors, namely uric acid, urea nitrogen, alkaline phosphatase, monoamine oxidase, alanine aminotransferase, glutathione, neutrophil percentage, and age. The model achieved areas under the curve (AUCs) of 0.800 (95%CI: 0.769-0.830), 0.787 (95%CI: 0.738-0.836), and 0.736 (95%CI: 0.667-0.835) in the training, internal validation, and external validation sets, respectively. The model demonstrated good calibration, and decision curve analysis showed clinical net benefit within the threshold probability range of 10%-80%. ConclusionThe developed model exhibits good discriminative ability and clinical utility, serving as an effective early screening tool for primary healthcare institutions.

AIM: To compare the control effect of spherical and toric orthokeratology on low-to-moderate myopia with astigmatism(-1.00--1.50 DC)in adolescents.METHODS: The clinical data of 119 cases(119 eyes)of low-to-moderate myopia with astigmatism(-1.00--1.50 DC)adolescents who were treated and fitted with orthokeratology in the ophthalmology department of Sichuan Provincial People's Hospital from June 2021 to January 2022 were retrospectively analyzed. They were divided into spherical group, with 65 cases(65 eyes), and toric group, with 54 cases(54 eyes)according to the type of orthokeratology. The changes of uncorrected visual acuity(UCVA), axial length and corneal astigmatism before and after wearing lenses were recorded to evaluate the therapeutic effect.RESULTS: The UCVA of both the groups significantly improved at 1 and 2 a after wearing lenses(all P<0.01); corneal astigmatism decreased, but there was no significant difference(all P>0.05); the axial length was longer than that before wearing lenses(P<0.01). There were no statistical significant differences in the UCVA and corneal astigmatism between the spherical group and the toric group(Fintergroup=0.829,Pintergroup=0.364; Fintergroup=0.997,Pintergroup=0.320); and there were no statistical significant differences in the axial length growth between the spherical group and the toric group after wearing lenses for 1 a(0.18±0.11 mm vs 0.17±0.14 mm), and 2 a(0.17±0.10 mm vs 0.16±0.10 mm; all P>0.05).CONCLUSION: Both orthokeratology lenses can improve the UCVA, reduce corneal astigmatism, and delay axial length growth of adolescents with low-to-moderate myopia with astigmatism(-1.00--1.50 DC), and there are no significant differences in the control effect of spherical design orthokeratology and the toric design orthokeratology on myopia.

With the advancement in big data and artificial intelligence technologies, the extensive application of omics technologies in traditional Chinese medicine(TCM) research has generated large experimental datasets, enabling the exploration of cross-scale correlations among massive data and thereby resulting in the shift toward a data-intensive research paradigm. The emerging approach of multi-omics data fusion analysis, emphasizing technical and computational tools, presents a potential breakthrough in this field. The holistic perspective of TCM aligns with the concept of multi-omics data fusion, yet the data types encountered exhibit high dimensionality with small sample sizes, necessitating data processing techniques such as dimensionality reduction. The current challenge lies in selecting suitable analytical methods for these data to enhance the systematic understanding of physiological functions and disease diagnosis/treatment processes. This paper explores the theories and frameworks of multi-omics data fusion, analyzes methods for fusing high-dimensional, small-sample multi-omics data in TCM, and aims to provide insights for advancing TCM research.

Objective:To explore the risk factors for postoperative lower extremity lymphedema in patients with cervical cancer and construct a nomogram prediction model.Methods:A retrospective case-control study was conducted. Using convenience sampling method, 750 cervical cancer patients in Ziyang People's Hospital from May 2014 to May 2022 were selected. The included patients were divided into a modeling group (525 cases) and a validation group (225 cases) according to a ratio of 7∶3. In the modeling group, patients were divided into a developing group and a non-developing group according to the incidence of postoperative lower extremity lymphedema. Self-designed baseline data questionnaire was used to collect clinical data of patients. Logistic stepwise regression analysis was used to analyze the influencing factor for the incidence of postoperative lower extremity lymphedema in cervical cancer patients. R 4.0.2 software was used to construct a nomogram model for predicting the incidence risk of postoperative lower extremity lymphedema in cervical cancer patients based on the independent risk factors. Receiver operating characteristic (ROC) curve was used to evaluate the differentiation of the nomogram prediction model. Calibration curves were drawn to evaluate the consistency of the nomogram prediction model.Results:Among 525 cervical cancer patients in the modeling group, 109 (20.76%) had postoperative lower extremity lymphedema. There were statistically significant differences in the proportions of patients with different ages, tumor stages, surgical methods, postoperative drainage time, continuous standing time, number of lymph node dissection, and with or without diabetes mellitus, postoperative chemotherapy, postoperative radiotherapy, strenuous exercise or physical labor between the developing group and the non-developing group (all P < 0.05). Multivariate logistic regression analysis showed that age ≥ 60 years old( OR = 2.548, 95% CI: 1.253-5.181), postoperative radiotherapy ( OR = 8.048, 95% CI: 3.867-16.749), postoperative drainage time ≥5 d ( OR = 2.664, 95% CI: 1.043-6.803), continuous standing time ≥ 1 h ( OR = 3.024, 95% CI: 1.252-7.305), number of lymph node dissection > 20 ( OR = 7.063, 95% CI: 1.595-31.281), comorbid diabetes mellitus ( OR = 2.617, 95% CI: 1.200-5.711), and strenuous exercise or physical labor ( OR = 3.518, 95% CI: 1.841-6.721) were all independent risk factors affecting the incidence of postoperative lower extremity lymphedema in cervical cancer patients (all P < 0.05). Based on the above risk factors, a nomogram model was established to predict the incidence risk of postoperative lower extremity lymphedema in cervical cancer patients, and internal and external validation was performed. The results showed that the calibration curves of the modeling group and the validation group showed a good fit to the ideal curves (modeling group: χ2 = 7.87, P = 0.446; validation group: χ2 = 7.92, P = 0.441); the area under the ROC curve was 0.839 (95% CI: 0.795-0.883) and 0.834 (95% CI: 0.783-0.885), respectively, indicating that the prediction model had good predictive efficacy. Conclusions:Age, postoperative radiotherapy, postoperative drainage time, continuous standing time, number of lymph node dissection, whether combined with diabetes mellitus and strenuous exercise or physical labor may be the influencing factors for the incidence of postoperative lower extremity lymphedema in cervical cancer patients. The constructed nomogram model has high clinical value in evaluating the incidence risk of postoperative lower extremity lymphedema in cervical cancer patients.
