RESUMEN
Objective To investigate the infection of Chlamydia pneumoniae and mycoplasma pneumoniae in adults and their association with atherosclerosis,and to provide theoretical guidance for the prevention of such diseases. Methods A case-control study was used to collect 362 patients who were diagnosed with atherosclerosis from January 2019 to December 2021 in Department of Sichuan Bazhong Central Hospital, and 370 cases who were admitted to the hospital during the same period of physical examination without any cardiovascular disease were selected as the control group, and whole blood samples of the two groups of study subjects were collected, and the infection of Chlamydia pneumoniae and mycoplasma pneumoniae was detected by PCR. Results The infection rate of Chlamydia pneumoniae was 35.49%, the infection rate of mycoplasma was 40.37%, and the co-infection rate was 11.37%；The infection rate of Chlamydia pneumoniae in the control group was 12.04%, the infection rate of mycoplasma was 15.83%, and the coinfection rate was 3.14%, and the difference between the two groups was statistically significant ( χ2=10.926, P=0.023). The effects of mycoplasma, chlamydia, and co-infection on atherosclerotic patients have sex differences, mainly manifested as higher infection rates in men; In addition, the effects of mycoplasma, chlamydia, and co-infection on atherosclerosis patients varied by age, mainly in the 55-70 years age group (P<0.05). Multivariate logistic regression results showed that Chlamydia pneumoniae infection was a risk factor for atherosclerosis (OR=1.303, 95%CI: 1.043-1.677) in the whole population, and chlamydia pneumoniae (OR=1.472, 95% CI: 1.037-1.556), mycoplasma (OR=2.003, 95%CI: 1.637-3.842) and co-infection in men (OR=1.937, 95%CI: 1.380-2.184) were risk factors for atherosclerosis, while co-infection in women (OR=1.699, 95%CI: 1.263-1.765) was a risk factor for atherosclerosis. Conclusion Chlamydia pneumoniae and mycoplasma infection are risk factors for atherosclerosis, and their impact on male groups is greater, and more attention needs to be paid to them.
RESUMEN
Objective: To development the prognostic nomogram for malignant pleural mesothelioma (MPM). Methods: Two hundred and ten patients pathologically confirmed as MPM were enrolled in this retrospective study from 2007 to 2020 in the People's Hospital of Chuxiong Yi Autonomous Prefecture, the First and Third Affiliated Hospital of Kunming Medical University, and divided into training (n=112) and test (n=98) sets according to the admission time. The observation factors included demography, symptoms, history, clinical score and stage, blood cell and biochemistry, tumor markers, pathology and treatment. The Cox proportional risk model was used to analyze the prognostic factors of 112 patients in the training set. According to the results of multivariate Cox regression analysis, the prognostic prediction nomogram was established. C-Index and calibration curve were used to evaluate the model's discrimination and consistency in raining and test sets, respectively. Patients were stratified according to the median risk score of nomogram in the training set. Log rank test was performed to compare the survival differences between the high and low risk groups in the two sets. Results: The median overall survival (OS) of 210 MPM patients was 384 days (IQR=472 days), and the 6-month, 1-year, 2-year, and 3-year survival rates were 75.7%, 52.6%, 19.7%, and 13.0%, respectively. Cox multivariate regression analysis showed that residence (HR=2.127, 95% CI: 1.154-3.920), serum albumin (HR=1.583, 95% CI: 1.017-2.464), clinical stage (stage Ⅳ: HR=3.073, 95% CI: 1.366-6.910) and the chemotherapy (HR=0.476, 95% CI: 0.292-0.777) were independent prognostic factors for MPM patients. The C-index of the nomogram established based on the results of Cox multivariate regression analysis in the training and test sets were 0.662 and 0.613, respectively. Calibration curves for both the training and test sets showed moderate consistency between the predicted and actual survival probabilities of MPM patients at 6 months, 1 year, and 2 years. The low-risk group had better outcomes than the high-risk group in both training (P=0.001) and test (P=0.003) sets. Conclusion: The survival prediction nomogram established based on routine clinical indicators of MPM patients provides a reliable tool for prognostic prediction and risk stratification.

Objective:To explore the accuracy of artificial intelligence (AI) system based on deep learning in evaluating bone age of children with abnormal growth and development.Methods:The positive X-ray films of the left wrist of children with abnormal growth and development who were treated at the Affiliated Hospital of Guizhou Medical University from January 2020 to December 2021 were collected retrospectively. A total of 717 children were collected, including 266 males and 451 females, aged 2-18 (11±3) years. Based on Tanner Whitehouse 3 (TW 3)-RUS (radius, ulna, short bone) and TW3-Carpal (carpal bone) method, bone age was measured by 3 senior radiologists, and the mean value was taken as reference standard. The bone ages were independently evaluated by the AI system (Dr.Wise bone age prediction software) and two junior radiologists (physicians 1 and 2). The accuracy within 0.5 year, the accuracy within 1 year, the mean absolute error (MAE) and the root mean square error (RMSE) between the evaluation results and the reference standard were analyzed. Paired sample t-test was used to compare MAE between AI system and junior physicians. Intraclass correlation coefficient (ICC) was used to evaluate the consistency between AI system, junior physician and reference standard. The Bland-Altman diagram was drawn and the 95% consistency limit was calculated between AI system and reference standard. Results:For TW3-RUS bone age, compared with the reference standard, the accuracy within 0.5 year of AI system, physician 1 and physician 2 was 75.3% (540/717), 62.1% (445/717) and 66.2% (475/717), respectively. The accuracy within 1 year was 96.9% (695/717), 86.3% (619/717) and 89.1% (639/717), respectively. MAE was 0.360, 0.565 and 0.496 years, and RMSE was 0.469, 0.634 and 0.572 years, respectively. For TW3-Carpal bone age, compared with the reference standard, the accuracy within 0.5 year of AI system, physician 1 and physician 2 was 80.9% (580/717), 65.1% (467/717) and 71.7% (514/717), respectively. The accuracy within 1 year was 96.0% (688/717), 87.3% (626/717) and 90.4% (648/717), respectively. MAE was 0.330, 0.527 and 0.455 years, and RMSE was 0.458, 0.612, 0.538 years, respectively. Based on TW3-RUS and TW3-Carpal bone age, the MAE of AI system were lower than those of physician 1 and physician 2, and the differences were statistically significant ( P all<0.001). The evaluation results of AI, physician 1 and physician 2 were in good agreement with the reference standard (ICC all>0.950). The Bland-Altman analysis showed that the 95% agreement limits of AI system for assessing TW3-RUS and TW3-Carpal bone age were -0.75-1.02 years and-0.86-0.91 years, respectively. Conclusion:The accuracy of AI system in evaluating the bone age of children with abnormal growth and development is close to that of senior doctors, better than that of junior doctors, and in good agreement with senior doctors.
RESUMEN
Diabetic ketoacidosis (DKA), a serious acute complication of diabetes mellitus, mainly manifests as hyperglycemia, ketosis, and acidosis. It is a metabolic syndrome resulting from insulin deficiency and increased insulin-antagonistic hormone levels. While type 2 diabetes mellitus complicated by DKA is relatively uncommon, secondary pneumomediastinum in DKA is extremely rare. Following alveolar rupture, air can travel through various routes to reach the hilum, causing anterior, middle, or posterior pneumomediastinum or even leading to intracranial epidural pneumatosis. The diagnosis of pneumomediastinum is mainly dependent on chest computed tomography findings. After the successful treatment of DKA, pneumomediastinum usually resolves spontaneously within 5-10 days with a good prognosis. One DKA patient admitted to Dege County People's Hospital developed Kussmaul respirations, followed by an increase in intra-alveolar pressure, an elevation in intra and extra-alveolar pressure difference, and protein decomposition in the alveolus wall, which promoted alveolar rupture and induced mediastinal emphysema. After rapid fluid replacement, blood glucose control with insulin, and maintenance of acid-base balance (correction DKA), the mediastinal emphysema was spontaneously absorbed. Through the analysis of the clinical data of this case, the purpose is to improve the clinicians' internal understanding of the relationship between mediastinal emphysema and DKA, avoid over-examination and over-treatment, and provide strategies for correct diagnosis and treatment.
RESUMEN
Objective:To investigate the expression and significance of programmed death ligand 1 (PD-L1) and programmed death 1 (PD-1) in colorectal cancer complicated by schistosomiasis.Methods:A total of 134 patients with colorectal cancer who received treatment in Xuancheng People's Hospital during 2014-2021 were included in this study. These patients consisted of 74 patients with colorectal cancer combined with schistosomiasis (patient group) and 60 patients with only colorectal cancer (control group). The expression of PD-L1 and PD-1 in colorectal cancer tissue was detected by an immunohistochemical method. The differences in PD-L1 and PD-1 expression were compared between the two groups. The relationships between PD-L1 and PD-1 expression and clinical pathological characteristics were determined.Results:The positive expression rates of PD-L1 and PD-1 in cancer cells and interstitial lymphocytes were 55.4% and 60.8% respectively in the patient group and they were 35.0% and 40.0% respectively in the control group. The positive expression rates of PD-L1 and PD-1 were significantly higher in the patient group than the control group ( χ2 = 5.55, 5.74, both P < 0.05). The expressions of PD-L1 and PD-1 in the patient group were correlated with lymph node metastasis and high tumor-node-metastasis stage ( P < 0.05). Conclusion:PD-L1 and PD-1 are highly expressed in colorectal cancer complicated by schistosomiasis and are related to their invasive behavior. PD-1/PD-L1 singaling pathway may be involved in the molecular mechanism underlying the occurrence and development of colorectal cancer complicated by schistosomiasis. Blocking PD-1/PD-L1 signaling pathway may be a new strategy for immunotherapy of colorectal cancer complicated by schistosomiasis.

RESUMEN
Objective:To analyze the diagnostic value of Michigan nerve screening Scale (MNSI), pain, touch and temperature detection combined with vibratory perception threshold (VPT) in diabetic peripheral neuropathy (DPN).Methods:A total of 500 patients with type 2 diabetes mellitus (T2DM) who received inpatient treatment in Xinhua Hospital Chongming Branch Affiliated of Shanghai Jiao Tong University School of Medicine from January to December 2018 were selected. Sixty four patients with DPN were enrolled in the DPN group, and the remaining 436 patients were enrolled in the no-DPN group. The clinical data and the results of MNSI scale, pain, touch and temperature detection thresholds and VPT of the two groups were compared. Receiver operating characteristic (ROC) curve was drawn to analyze the clinical value of single and combined examination indicators in the diagnosis of DPN.Results:MNSI symptom questionnaire score and MNSI physical examination score in DPN group were higher than those in no-DPN group: (3.00 ± 1.35) scores vs. (1.69 ± 0.52) scores, (1.57 ± 0.50) scores vs. (1.01 ± 0.24) scores; the proportion of touch regression, pain regression and temperature regression was significantly higher than that in no-DPN group; and the levels of VPT in the DPN group was higher than that in the no-DPN group: (26.34 ± 5.03) V vs. (17.97 ± 6.82) V, there were statistical differences ( P<0.01). When the single index was diagnosed, the area under the curve (AUC) value of VPT was the highest (0.825), and significantly higher than the pain, touch and temperature detection ( P<0.01). The AUC value of VPT + MNSI in combined diagnosis was the highest (0.738), and the sensitivity and specificity of DPN diagnosis were 51.56% and 96.10%, respectively. Conclusions:Compared with MNSI scale score, sensory detection such as pain, touch and temperature, VPT has the best diagnostic efficiency for DPN, while combined with MNSI, the specificity can be further improved, but the sensitivity decreases, which is worthy of clinical attention.
RESUMEN
【Objective】 To explore the efficacy of modified prostate tip separation technique combined with laparoscopic radical prostatectomy based on propensity score matching (PSM) in the treatment of prostate cancer. 【Methods】 A total of 74 prostate cancer patients treated during Jan.2019 and Dec.2022 with modified prostate tip separation technique combined with laparoscopic radical prostatectomy were included in the combined group, and another 63 prostate cancer patients treated during the same period with laparoscopic radical prostatectomy were selected as the control group. Altogether 58 pairs of patients were matched with PSM. The perioperative indicators, incidence of complications, urinary control function and sexual function before and one month after surgery between the two groups after matching were compared. 【Results】 There were no statistically significant differences in general data between the two groups (P>0.05). One month after operation, the scores of the International Urinary Incontinence Questionnaire (ICIQ-SF) and International Erectile Function Questionnaire (IIEF-5) in both groups decreased, while the Expanded Prostate Cancer Index Composite (EPIC-UIN) and International Prostate Symptom Score (IPSS) in both groups increased (P<0.05). The scores of ICIQ-SF [(9.02±1.98) vs. (11.38±2.04)] and IPSS [(19.67±4.19) vs. (21.68±4.23)] were lower in the combined group than in the control group (P<0.05), while the scores of EPIC-UIN [(70.49±6.82) vs. (63.34±6.48)] and IIEF-5 [(18.17±1.73) vs. (16.72±1.58)] were higher in the combined group than in the control group (P<0.05). Compared with the control group, the combined group had shorter catheter retention time [(7.38±1.97) d vs. (5.11±1.82) d] and hospital stay [(13.18±2.23) d vs. (11.74±2.09) d], lower incidence of complications (22.41% vs. 6.90%), and higher positive rate of incision margin (8.62% vs. 20.69%) (P<0.05). 【Conclusion】 PSM can balance the differences between groups. The modified prostate tip separation technique combined with laparoscopic radical prostatectomy can improve the urinary control function, have little impact on sexual function, and cause fewer postoperative complications. However, the risk of positive incision margin is high, and further modification is needed to achieve the best therapeutic effects.

RESUMEN
Objectives To explore and compare the clinical characteristics and risk factors for mortality between patients with artificial quartz stone silicosis and those with classic silicosis. Methods A total of 48 patients with artificial quartz stone silicosis (experiment group) and 98 patients with classic silicosis (control group) were recruited as the research subjects using the convenience sampling method. Data of clinical symptoms, laboratory tests, high-resolution computed tomography (HRCT), and pulmonary pathology of the research subjects were retrospectively analyzed. The Cox proportional hazards regression model was used to analyze the influencing factors on the survival time of silicosis patients. Results Patients in the experiment group had shorter years of dust exposure, latency period and time since last exposure than those in the control group (all P<0.01). The positive rate of anti-nuclear antibodies and the expression of neuron-specific enolase in the experiment group were higher than those in the control group (39.6% vs 10.2%, median： 28.44 vs 16.25, both P<0.01). The PaO2 levels in the experiment group were lower than those in the control group (median： 66.0 vs 89.0, P<0.01). The patients in the experiment group had lower vital capacity, inspiratory reserve volume, forced expiratory volume in the first second (FEV1), forced vital capacity (FVC), and carbon monoxide diffusion capacity compared to the control group (all P<0.05), but the maximal expiratory flow in 75% vital capacity was higher than the control group (P<0.05). Compared with the control group, patients in the experiment group had the presence of ground-glass opacity (GGO) in both lungs, aggregation and fusion of subpleural nodules, and gradual formation of progressive massive fibrosis (PMF), with higher potential of pneumothorax. Within 5 years after diagnosis, the mortality of patients in the experiment group was higher than that in the control group (27.1% vs 4.1%, P<0.01). The Cox regression model analysis results showed that patients with nodule aggregation on lung HRCT images had a higher risk of mortality than those without nodule aggregation, and lower lung function including vital capacity, FVC, FEV1 and maximum expiratory flow in 25% vital capacity had higher risk of reduced survival time (all P<0.05). Conclusion Compared with patients with classic silicosis, patients with artificial quartz stone silicosis have higher level of serum neuron-specific enolase, increasing the risk of autoimmune diseases. Pulmonary imaging features in patients with artificial quartz stone silicosis include GGO, PMF and susceptibility to pneumothorax, and rare calcification of mediastinal lymph nodes, leading to a higher mortality rate within 5 years after diagnosis.

RESUMEN
BACKGROUND@#Hyaluronic acid dermal fillers are composed of cross-linked viscoelastic particles with high biocompatibility. The performance of the fillers is determined by the viscoelastic properties of particles and the connecting force between particles. However, the relationships among the properties of fillers, the interaction of the gels and the surrounding tissue are not clear enough.METHOD: Four kinds of typical dermal filler were selected in this research to reveal the interaction between the gels and cells. A series of analytical tools was applied to characterize the structure and physicochemical properties of the gel, as well as observing their interaction with the surrounding tissues in vivo and discussing their internal mechanism.RESULT: The large particles internal the gel and the high rheological properties endow the Restylane2 with excellent support. However, these large-size particles have a significant impact on the metabolism of the local tissue surrounding the gel. Juvéderm3 present gel integrity with the high cohesiveness and superior support. The rational matching of large and small particles provides the Juvéderm3 with supporting capacity and excellent biological performance. Ifresh is characterized by small-size particles, moderate cohesiveness, good integrity, lower viscoelasticity and the superior cellular activity located the surrounding tissues. Cryohyaluron has high cohesion and medium particle size and it is prominent in cell behaviors involving localized tissues. Specific macroporous structure in the gel may facilitate the nutrients delivering and removing the waste. @*CONCLUSION@#It’s necessary to make the filler both sufficient support and biocompatibility through the rational matching of particle sizes and rheological properties. Gels with macroporous structured particle showed an advantage in this area by providing a space inside the particle.
RESUMEN
Disintegration time is a key parameter that affects the palatability and compliance of oral soluble films. At present, there is no standard method to determine the disintegration time of oral soluble films. In this study, we compared the six methods (pharmacopoeial disintegration method, petri dish method, sponge surface method, slide frame and ball method, partially immersed into liquid (without weight attached) and partially immersed into liquid (with weight attached)) to determine the in vitro disintegration time of oral soluble films with different thickness, and evaluated the correlation with the in vivo disintegration time. The results showed that the repeatability and correlation of pharmacopoeial disintegration method and the partially immersed into liquid method (with weight attached) were excellent, with the endpoint of disintegration testing easy to determine. Partially immersed into liquid method (with weight attached), properly simulating the physiological condition in oral cavity, showed strong operability, good repeatability and in vitro-in vivo correlation, and was suitable for in vitro disintegration evaluation of oral soluble film dosage form. The adult sensory evaluation study was a research-based clinical trial conducted with informed consent from all subjects in accordance with the ethical requirements of Good Clinical Practice.
RESUMEN
Licorzine granules are common preparations for children zinc deficiency. Considering the long course of treatment, the taste of licorzine granules may become a main factor affecting medication adherence. To date there have been no taste evaluation research into licorzine granules yet. In this study, both sensory evaluation and electronic tongue method were utilized to optimize licorzine granules formulations, evaluate the tastes of licorzine, excipients, optimized formulation in vivo and in vitro. As the results show, bitterness and astringency are the main unpleasant tastes generating from licorzine. Xanthan gum is the main taste-masking excipient, lowering down the bitterness and astringency of licorzine by at least one grade. Good correlation exists between the results of sensory evaluation and electronic tongue method, and an integrated combination of the two helps to obtain objective and rational research conclusions. The adult sensory evaluation study was a research-based clinical trial conducted with informed consent from all subjects in accordance with the ethical requirements of Good Clinical Practice.
RESUMEN
Glaucoma is a chronic optic neuropathy that affects the retinal ganglion cells, characterized by optic disc atrophy, visual field defects, and visual acuity loss. Since glaucoma is a chronic disease, long-term use of topical intraocular pressure-lowering medications often leads to ocular surface diseases, thus reducing medication adherence and ultimately affecting treatment efficacy. Currently, topical intraocular pressure-lowering medications include prostaglandin derivatives, β-adrenergic blockers, α-adrenergic agonists, topical carbonic anhydrase inhibitors, and cholinergic drugs. This article provides a comprehensive review of the effects and related mechanisms of these five antiglaucoma medications on the ocular surface of glaucoma patients and offers preventative measures for the protection of ocular surface in glaucoma patients.

The patients were grouped by the levels of ALBI score. The survival data were obtained through telephone or outpatient review. The Kaplan-Meier method was used to draw the survival curve. Multivariate analysis was performed using the Cox regression analysis model. The time-dependent receiver operating characteristic (ROC) curve was plotted to compare the prognostic value of the scoring system. A nomogram based on ALBI grade was established and its predictive performance was evaluated.Results:The 1, 3, 5 years overall survival (OS) rates of patients with gallbladder cancer were 76.7%, 52.5%, and 41.9%, respectively. The time-dependent ROC curves revealed that the area under the curve (AUC) values of ALBI grade were 0.659, 0.597 and 0.599 for 1, 2 and 3 years, showing a good prognostic performance. Multivariate regression analysis showed that poorer tumor differentiation ( HR=2.890, 95% CI: 1.816-4.600, P<0.001), TNM Ⅲ/Ⅳ stage ( HR=2.832, 95% CI: 1.781-4.503, P<0.001), ALBI grade 2 ( HR=1.595, 95% CI: 1.017-2.500, P=0.042), and ALBI grade 3 ( HR=3.938, 95% CI: 1.375-11.278, P=0.011) were independent risk factors for OS. The nomogram established with the independent risk factors such as ALBI grade showed a good predictive value for OS. The ROC curve results showed that the AUC values for 1, 3 and 5 years were 0.796, 0.806 and 0.799, respectively. The calibration plots and clinical decision curve analysis (DCA) showed the clinical feasibility of this nomogram. Conclusion:The nomogram model based on ALBI grading has a good predictive value for gallbladder cancer after surgery, which could guide the prognosis and individualized treatment decision-making.
