RESUMEN
Background and purpose:The plasma used for routine coagulation test(CCT)can only reflect a single component at a certain coagulation time point/segment,while thromboelastography(TEG)can depict the overall dynamic process curve of coagulation and fibrinolysis,which can more independently and completely reflect the true state of the blood and can serve as a supplement to coagulation function testing.This study aimed to evaluate the application value of combined coagulation function indexes in monitoring the hypercoagulable state of patients with colorectal cancer after chemotherapy,and to explore the risk factors of thrombosis in patients with colorectal cancer after chemotherapy,so as to provide reference for clinical monitoring of hypercoagulable state.Methods:A total of 160 patients with colorectal cancer from Fudan University Shanghai Cancer Center from June 2021 to June 2023 were selected as the experimental group,and 80 healthy subjects were selected as the control group.Then the experimental group was divided into a group without thrombosis(82 cases)and a group with thrombosis(78 cases)according to whether they had thrombosis or not.The determinations of thromboelastography(TEG)[coagulation reaction time(R),coagulation formation time(K),blood clot formation rate(α-Angle),maximum amplitude(MA)and coagulation index(CI)],conventional coagulation tests(CCT)[activated partial thromboplastin time(APTT),prothrombin time(PT),thrombin time(TT),fibrinogen(Fib),D-dimer(DD),fibrinogen degradation products(FDP)]and platelet count(PLT)were studied among three groups.With or without thrombosis as the criterion of hypercoagulable state,statistically significant indicators were selected to be included in the binary logistic regression analysis,and the receiver operating characteristic(ROC)curve was drawn to analyze the diagnostic efficacy of single and combined detection of the coagulation function indicators for hypercoagulable state in patients with colorectal cancer after chemotherapy.Basic information,tumor stage and Autar score of deep vein thrombosis were collected in 160 patients with colorectal cancer.Logistic regression analysis was performed to explore the risk factors of thrombosis.This study was approved by the Ethics Committee of Fudan University Shanghai Cancer Center(number:050432-4-2108*).Results:Compared with the control group,the R,TT and PLT of the group with thrombosis were decreased(P＜0.05),while APTT,PT,DD and FDP were increased(P＜0.05).The differences in various indicators between the group with thrombosis and the control group were statistically significant(P＜0.05).Compared with the group without thrombosis,the K in the group with thrombosis decreased(P＜0.05),while Angle,MA,CI,FIB,DD and FDP all increased(P＜0.05).ROC curve analysis showed that in the assessment of hypercoagulable state in patients with colorectal cancer after chemotherapy,the area under curve(AUC)of TEG was 0.756,sensitivity was 67.5%,and specificity was 73.8%.The AUC of CCT was 0.691,sensitivity was 78.8%,and specificity was 56.2%.The combined detection AUC was 0.840,sensitivity was 80.0%,and specificity was 77.5%.In the analysis of risk factors,tumor stage,distant metastasis and Autar score were correlated with thrombus formation in patients with colorectal cancer after chemotherapy(P＜0.05),and the differences of the three risk factors in K,Angle,MA,CI,Fib,DD and FDP were statistically significant(P＜0.05).Conclusion:K,Angle,MA,CI,Fib,DD and FDP are the main indicators to reflect the hypercoagulable state,and the combined detection of TEG and CCT can better reflect the coagulation state of patients with colorectal cancer after chemotherapy.Tumor stage Ⅲ to Ⅳ,distant metastasis and high Autar score are risk factors for thrombosis.The incidence of thrombosis can be reduced by monitoring the relevant coagulation indicators in the high-risk population.

RESUMEN
Objective To investigate the effect and possible mechanism of microRNA-26a(miR-26a)on the syn-thesis of extracellular matrix(ECM)induced by high glucose(HG)in renal tubular epithelial cells(RTECs).Methods A model of diabetic kidney disease(DKD)was constructed by inducing RTECs with HG.MiR-26a was overexpressed in HG-induced RTECs,and RT-qPCR and Western blot were used to assess the effects of miR-26a on ECM synthesis and ferroptosis-related markers in HG-treated RTECs.Ferrostatin(Fer-1)was used to inhibit ferroptosis in the DKD model,and its impact on ECM synthesis was evaluated.RT-qPCR and Western blot were performed to measure ferroptosis-related markers,and fluorescence microscopy was used to observe the intensity of reactive oxygen species(ROS).Results Compared with the control group,the expression of miR-26a decreased in HG-treated cells,while the expression levels of ECM synthesis-related indexes fibronectin and collagen Ⅰ in-creased.After overexpressing miR-26a,the HG+miR-26a group showed a significant increase in miR-26a expres-sion and a decrease in fibronectin and collagen Ⅰ expression compared to the HG group.In terms of ferroptosis,the protein and mRNA expression of SLC7A11 and GPX4 significantly decreased,the expression of TFR-1 and AC-SL4 significantly increased,and the fluorescence intensity of ROS was significantly enhanced in the HG group com-pared with the control group.Inhibition of ferroptosis in the HG+Fer-1 group resulted in significant changes in fer-roptosis and ECM synthesis-related indicators expression levels compared to the HG group.Furthermore,re-expres-sion of miR-26a in the HG+miR-26a led to significant changes in ferroptosis-related indicators expression levels and decreased ROS fluorescence intensity compared to the HG group.Conclusions In HG-induced RTECs,miR-26a inhibits the occurrence of ferroptosis,thus reducing ECM synthesis.
RESUMEN
BACKGROUND:The medial patellofemoral ligament reconstruction is the most commonly used method for the treatment of lateral dislocation of patella at present.The ultimate goal is to adjust the patella to the normal anatomical position and restore the patella track.Currently,the main core problem of medial patellofemoral ligament reconstruction is the selection of its femoral end fixation point. OBJECTIVE:Finite element method was used to analyze the limiting effect of the reconstructed medial patellofemoral ligament on the patella at different flexion angles of the knee joint,and to simulate the limiting effect of medial patellofemoral ligament reconstruction at different fixation points of the femoral end on the patellofemoral end,so as to provide help for the selection of fixation points of the femoral end during the reconstruction of the medial patellofemoral ligament. METHODS:A finite element model of knee including bone and soft tissue was established according to the extracted CT and MRI data of knee joint.When the knee flexion angle of 30° and 60° was simulated,the medial patellofemoral ligament was constructed by selecting different fixation points of femur end.The contact stress and contact area between patellofemoral joints at different points were compared,as well as the transverse binding force on patella.The equilength of the medial patellofemoral ligament constructed from the same fixation point of the femoral end at different flexion angles was verified to study the effect of various reconstruction positions of the medial patellofemoral ligament. RESULTS AND CONCLUSION:(1)A three-dimensional finite element model of the knee joint at 30° and 60° flexion angles was established to construct the medial patellofemoral ligament at different fixation points of the femur end.The medial patellofemoral ligament constructed at the same position of the femur end had usable isometric length at different flexion angles.(2)After the lateral displacement of the patella,in the transverse direction,the medial patellofemoral ligament constructed at different fixed points of the femur end produced different transverse binding force on the patella,and the transverse binding force was maximum at the anterior 10 mm and minimum at the proximal 5 mm.In the longitudinal direction,the location and size of stress concentration points on the patella cartilage were roughly the same,and the contact pressure did not change much.However,the contact area between the patella cartilage and the femoral cartilage was significantly different,with the maximum contact area at 10 mm at the front end and the minimum contact area at 5 mm at the proximal end.(3)The medial patellofemoral ligament constructed at the center of the saddle region has a good lateral restriction on the patella,but does not cause excessive restriction on the patella in the longitudinal restriction,and can achieve a good restriction on the patella.
RESUMEN
BACKGROUND:The injury of the anterior talofibular ligament is most common in joint ligament injuries.The use of the finite element method to simulate ankle joint motion has the advantages of short experimental time,complex boundary conditions that can be simulated,and mechanical properties. OBJECTIVE:To analyze the effect of the anterior talofibular ligament on the stress distribution of the talus trochlea and the stability of the ankle joint. METHODS:A finite element model of the ankle was established based on CT and MRI images of patients with anterior talofibular ligament injury who were followed up for two months after Brostr?m surgery to simulate ankle joint stress in patients with anterior talofibular ligament injury before and after surgery during normal gait cycles(ground phase,neutral phase,and off-ground phase).The stress distribution and maximum stress value of the talus bone cartilage were measured before and after surgery,and their differences were analyzed. RESULTS AND CONCLUSION:Under normal gait,the anterior talofibular ligament has a certain protective effect on the talus trochlea in any position,reducing the wear of the ankle joint on the talus trochlea during movement.In all three phases,stress concentration was observed on the surface of the talus trochlea near the inner side of the ankle joint.The influence of the anterior talofibular ligament on the stability of the talus trochlear is much greater in the off-ground phase than in the ground phase and neutral phase.Under certain circumstances,the greater the torque on the ankle joint,the more significant the effect of the anterior talofibular ligament on the stability of the talus trochlea.
RESUMEN
High security and effectiveness are critical performance metrics in the data transmission process for satellite remote sensing images, medical images, and so on. Previously, the receiver could gain a high-quality cover image (lossy) after decryption in a separable manner to balance embedding capacity (EC) and security. Completely separable, reversible data hiding in encrypted image (SRDH-EI) algorithms are proposed to address this issue. In this study, the cover image was preprocessed at the sender's end. The pre-embedded pixels and most significant bits (MSB) were compressed via two coding methods to reserve space. Additionally, the header data were embedded for marking. Finally, auxiliary data and secret data were embedded in a forward "Z" and reverse "Z" shape before and after encryption, respectively. The receiver could extract secret data and decrypt the cover image separately using the keys and markers. The experimental results demonstrate that the algorithm reached a high EC for remote sensing images by utilizing pixel correlation at multiple positions within the groups. The cover image could maintain its entropy during the data embedding process, ensuring security. The decrypted image could be recovered without distortion, furthermore, the receiver could achieve complete separability, so it has good application prospects for remote sensing images.
RESUMEN
The purpose of this study was to determine the diagnostic efficacy of Xpert MTB/RIF assay for rapid diagnosis of Tuberculosis (TB) and detection of rifampicin (RIF) resistance in patients suspected of having EPTB, assessing it against traditional culture and drug susceptibility test (DST) by proportional method, and the ability to predict multidrug resistance TB by Xpert MTB/RIF assay. In this study, the Xpert MTB/RIF assay was applied to 1,614 extrapulmonary specimens. Compared with TB culture and Composite Reference Standard (CRS), the Xpert MTB/RIF assay had a high sensitivity and specificity for detection of EPTB. Depending on the culture method or CRS as the standard, sensitivity of the Xpert MTB/RIF assay for detection of MTB in pleural effusion, cerebrospinal fluid, thoracic drainage fluid and throat swabs specimens were lower than that of other specimens. According to the experimental results, we have reason to believe that Xpert MTB/RIF assay is a rapid and simple technique with high sensitivity and specificity for diagnosing EPTB and detecting drug resistance in variety of specimens. Xpert MTB/RIF assay combined with DST maybe identify more cases of multi-drug resistant tuberculosis (MDR-TB).

RESUMEN
Background: Hypoglycemia is the most common adverse consequence of treating diabetes, and is often due to suboptimal patient self-care. Behavioral interventions by health professionals and self-care education helps avoid recurrent hypoglycemic episodes by targeting problematic patient behaviors. This relies on time-consuming investigation of reasons behind the observed episodes, which involves manual interpretation of personal diabetes diaries and communication with patients. Therefore, there is a clear motivation to automate this process using a supervised machine learning paradigm. This manuscript presents a feasibility study of automatic identification of hypoglycemia causes. Methods: Reasons for 1885 hypoglycemia events were labeled by 54 participants with type 1 diabetes over a 21 months period. A broad range of possible predictors were extracted describing a hypoglycemic episode and the subject's general self-care from participants' routinely collected data on the Glucollector, their diabetes management platform. Thereafter, the possible hypoglycemia reasons were categorized for two major analysis sections - statistical analysis of relationships between the data features of self-care and hypoglycemia reasons, and classification analysis investigating the design of an automated system to determine the reason for hypoglycemia. Results: Physical activity contributed to 45% of hypoglycemia reasons on the real world collected data. The statistical analysis provided a number of interpretable predictors of different hypoglycemia reasons based on self-care behaviors. The classification analysis showed the performance of a reasoning system in practical settings with different objectives under F1-score, recall and precision metrics. Conclusion: The data acquisition characterized the incidence distribution of the various hypoglycemia reasons. The analyses highlighted many interpretable predictors of the various hypoglycemia types. Also, the feasibility study presented a number of concerns valuable in the design of the decision support system for automatic hypoglycemia reason classification. Therefore, automating the identification of the causes of hypoglycemia may help objectively to target behavioral and therapeutic changes in patients' care.
RESUMEN
BACKGROUND: Mantle cell lymphoma (MCL) is an uncommon heterogeneous subtype of B cell non-Hodgkin lymphoma, and clinical features in MCL appear regional characteristics. MCL treatment opinions are not uniform between countries or regions within Asia and China, and Asian patient-specific data for MCL treatment are fewer. The study aims to explore the clinical characteristics, treatment patterns and prognosis of MCL patients in China. METHODS: A total of 805 patients diagnosed with MCL between April 1999 and December 2019 at 19 comprehensive hospitals in China were included in this retrospective analysis. Kaplan-Meier method coupled with the log-rank test was used for univariate analysis, and COX proportional hazards model was used for multivariate analysis (MVA). p < 0.05 was consided statistically significant. All outputs were produced using R version 4.1.0. RESULTS: The median age of the cohort was 60.0 years with a male-to-female ratio of 3.36:1. Five-year progression-free survival (PFS) and overall survival (OS) rates were 30.9% and 65.0%, respectively. High-intermediate/high-risk group according to MIPI-c, without high-dose cytarabine, lack of Auto-SCT as consolidation and maintenance treatment and SD/PD in initial treatment remained statistically relevant to poor PFS on MVA, and ki67 ≥50%, B symptoms, high-intermediate/high risk group according to MIPI-c, without high-dose cytarabine, lack of maintenance treatment, SD/PD in initial treatment and relapse/refractory state were independently associated with poorer OS on MVA. CONCLUSIONS: First-line high dose cytarabine exposure, auto-SCT as consolidation therapy obtained survival benefits in Chinese population. Our study further confirmed the value of maintenance treatment and explored the application of new drug treatment and bendamustine in R/R MCL patients.

OBJECTIVE: To investigate how the "special effect"/ "coeffect"/"synergistic effect" can achieve a positive result using an "acupuncture prescription" for functional gastrointestinal disorders (FGIDs) in clinical practice, based on the characteristics of single/compatible acupoints and acupuncture techniques. METHODS: According to the search strategy, we searched six electronic bibliographic databases and provided a summary for this overview. RESULTS: A large body of evidence has shown that acupuncture has positive effects in the treatment of FGIDs. However, the "prescription" intervention involved different single acupoints, compatible acupoints and acupoints based on expert consensus. CONCLUSIONS: The core acupoints, including Tianshu (ST25), Zusanli (ST36), and Shangjuxu (ST37), emphasize the application of special acupoints, meridian points and nerve segments, and the two-way regulatory effect found in this study is often used as the basis of acupoint selection and acupoint prescription for acupuncture treatment of FGIDs.

AIMS: To examine real-world capillary blood glucose (CBG) data according to HbA1c to define proportions of CBG readings at different HbA1c levels, and evaluate patterns in CBG measurements to suggest areas to focus on with regard to self-management. METHODS: A retrospective analysis stratified 682 adults with type 1 diabetes split into quartiles based on their HbA1c . The proportions of results in different CBG ranges and associations with HbA1c were evaluated. Patterns in readings following episodes of hyperglycaemia and hypoglycaemia were examined, using glucose to next glucose reading table (G2G). RESULTS: CBG readings in the target range (3.9-10 mmol/L) increase by ~10% across each CBG quartile (31% in the highest versus 63% in the lowest quartile, p < 0.05). The novel G2G table helps the treatment-based interpretation of data. Hypoglycaemia is often preceded by hyperglycaemia, and vice-versa, and is twice as likely in the highest HbA1c quartile. Re-testing within 30 min of hypoglycaemia is associated with less hypoglycaemia, 1.6% versus 7.2%, p < 0.001, and also reduces subsequent hyperglycaemia and further hypoglycaemia in the proceeding 24 h. The coefficient of variation, but not standard deviation, is highly associated with hypoglycaemia, r = 0.71, and a CV ≤ 36% equates to 3.3% of CBG readings in the hypoglycaemic range. CONCLUSIONS: HbA1c <58 mmol/mol (7.5%) is achievable even when only ~60% of CBG readings are between 3.9-10 mmol/L. Examining readings subsequent to out-of-range readings suggests useful behaviours which people with type 1 diabetes could be supported to adhere to, both in a clinic and structured education programmes, thereby decreasing the risk of hypoglycaemia whilst also reducing hyperglycaemia and improving HbA1c .

Objective: To investigate the clinicopathological features, immunophenotype and gene alterations of thyroid-like low-grade nasopharyngeal papillary adenocarcinoma (TL-LGNPPA). Methods: Fifteen case of TL-LGNPPA diagnosed at Zhejiang Cancer Hospital (5 cases) and the First Affiliated Hospital, Zhejiang University School of Medicine (10 cases) from November 2011 to August 2020 were collected. Clinical and pathological examinations, immunohistochemical staining and next-generation sequencing were performed. The clinicopathological and molecular characteristics were summarized, and relevant literature was reviewed. Results: Fifteen patients were identified and included. Their median age was 36 years (range, 20-60 years). The male-female ratio was 1.0∶1.1. The most common symptoms were epistaxis and nasal obstruction. The neoplasms were located on the roof of the nasopharynx or the posterior margin of the nasal septum. The pathological features included complex papillary and glandular structures mainly composed of single or pseudostratified cubic and columnar cells, with mild to moderate cytological atypia. In some cases, spindle cell features, nuclear grooves, ground glass nuclei, squamous metaplasia, or scattered psammoma bodies were identified. In addition, nuclear polar reversal cells, hobnail cells and micropapillary structures were found, but have not been reported in previous literature. Immunohistochemistry showed that the tumor cells were diffusely positive for TTF1, CK7, vimentin and CKpan; focally positive for p40, CK5/6 and p16; and negative for Tg, NapsinA, CK20, CDX2, S-100 and PAX8. The Ki-67 positive rates ranged from 1% to 20% and were≤10% in thirteen cases (13/15). EBER in situ hybridization was negative in all cases. DNA sequencing of 6 specimens was performed and all specimens were found harboring gene mutations (EWSR1, SMAD2, ROS1, JAK3, GRIN2A, ERRCC5, STAT3, and TET2), but no hot spot gene alterations were found. No MSI-H and MMR related gene changes were detected. All tumors showed low tumor mutation burden. All 15 patients underwent endoscopic surgery, and only 1 of them underwent radiotherapy postoperatively. All patients were recurrence free and alive at the end of follow-up periods (range: 23 to 129 months). Conclusions: TL-LGNPPA is a rare indolent tumor of the nasopharynx and exhibits a unique morphology and immunophenotype. Endoscopic resection is an effective treatment for TL-LGNPPA with excellent overall prognosis.

Objective:To explore the value of fetal lung volume and mediastinal shift angle (MSA) based on fetal MRI in predicting the prognosis of congenital diaphragmatic hernia (CDH).Methods:Fetuses with left CDH that did fetal MRI in Xinhua Hospital Affiliated with Shanghai Jiao Tong University School of Medicine from September 2016 to January 2022 were retrospectively collected. There were 65 patients, and their gestational age was 29 (26, 35) weeks when they were diagnosed with left CDH by MRI. Observed fetal lung volume and MSA were measured based on fetal MRI, and observed/expected lung volume (o/eFLV) based on gestational age was calculated. The clinical data were collected from birth to discharge, and patients were divided into survival group and death group in case of prognosis at discharge, with 54 cases in the survival group and 11 cases in the death group. The student′s t test was used to compare the difference of o/eFLV and MSA between the survival group and the death group, and the receiver operating characteristic (ROC) curve was used to evaluate the value of o/eFLV and MSA in predicting the prognosis of left CDH. Results:The o/eFLV of the survival group was 51.5%±18.3%, higher than that of the death group (27.8%±4.4%), and the difference was significant ( t=8.29, P<0.001). The MSA of the survival group was 33.1°±1.2°, lower than that of the death group (41.8°±2.7°), and the difference was significant ( t=-11.15, P<0.001). The area under the ROC curve (AUC) of o/eFLV to predict the fetal survival or death was 0.939 (95%CI 0.851-0.983), the cutoff value was 33.8%, the sensitivity was 100%, the specificity was 88.9%. The AUC of MSA was 0.998 (95%CI 0.941-1.000), the cutoff value was 37.2°, the sensitivity was 100%, the specificity was 98.2%. Conclusions:The o/eFLV and MSA that were measured based on fetal MRI can effectively predict the fetus′s prognosis with left CDH.
RESUMEN
Objective: To explore the vaccination coverage of the 13-valent pneumococcal conjugate vaccine (PCV13) in China from 2017 to 2021. Methods: Using the reported number of PCV13 administrated doses from 2017 to 2021 and the population data from 31 provinces in China, which were collected by the Immunization Program Information System and summarized data at different levels (prefecture, provincial, and national). Collecting batch release data of PCV13 during the same period through the official website of the National Institutes for Food and Drug Control. The average coverage level of PCV13 was calculated by comparing the number of PCV13 vaccinations reported annually to the number of births in that year, and the spatial auto-correlation analysis was conducted in 2021 at the prefecture level. The coverage of PCV13 vaccination was estimated by the total vaccine doses administered each year divided by the number of newborn in the year, as of the administrated dose number per 100 people. Results: From March 2017 to December 2020, the total batch release of PCV13 was 20.06 million, with a total of 71.54, 384.75, 475.45, and 10.8886 million doses each year. During the same period, PCV13 reported doses were 20.2369 million and the vaccination doses from 2017 to 2021 were 4.08, 170.46, 407.52, 599.77, and 8.4185 million doses, respectively. From 2017 to 2021, the ratio of PCV13 doses administrated per 100 infants in each year was 0.25, 10.26, 23.81, 38.16, and 69.90 doses per 100 people, respectively. The range of the ratio in each province increased from 3.85 doses in 2017 to 264.41 doses per 100 people in 2021. The spatial auto-correlation analysis results showed that based on prefecture-level cities, there was spatial clustering in a certain area of PCV13 coverage from 2017 to 2021, and the spatial correlation in 2021 was the highest. The hotspot analysis showed that the hotspot areas with high coverage levels of PCV13 were concentrated in Jiangsu, Zhejiang, Shanghai, Fujian and their surrounding areas. The cold spots with low vaccine coverage were concentrated in Yunnan, Qinghai, Tibet, and their surrounding areas. Conclusion: The average coverage level of PCV13 is low in China with significant regional differences.
