RESUMEN
Objective:To explore the technical focus of robotic-assisted laparoscopic surgery for the treatment of horseshoe kidney combined with renal tumor.Methods:The clinical data of a patient with horseshoe kidney combined with renal tumor treated by robot-assisted laparoscopic partial nephrectomy in the Second Hospital of Dalian Medical University in September 2021 were retrospectively analyzed. PubMed, CNKI, Wanfang and VIP databases were searched for all the literature on the use of robot-assisted laparoscopic nephrectomy or partial nephrectomy for the treatment of horseshoe kidney combined with renal tumor from the time of establishment to December 2022.Results:A total of 11 patients from 10 articles were retrieved and 12 patients were enrolled. Among the 12 patients, 4 cases used the retroperitoneal approach and 8 cases used the transperitoneal approach. Two cases were operated by traditional laparoscope, and the arteries were searched for and controlled before the robotic arm was placed to perform the partial nephrectomy and suture; and 10 cases were operated with the robotic-assisted laparoscopic approach throughout the whole procedure. Five cases of nephrectomy were performed on one side, and 7 cases were performed in the partial nephrectomy. Postoperative pathological diagnosis was clear cell carcinoma in 8 cases, chromophobe cell carcinoma in 1 case, eosinophilic cell carcinoma in 1 case, renal cell carcinoma in 1 case, and renal abscess in 1 case. The patient in the Second Hospital of Dalian Medical University was 38 years old female who was admitted to the hospital with a fever. After CT arteriography and three-dimensional reconstruction, robotic-assisted laparoscopic partial nephrectomy of right kidney and isthmus dissecting was performed. During the operation, tumor trophoblast vessels were ligated and dissected one by one by using single-use tissue closure clips, and the isthmus was dissected using endoscopic cutting anastomosis on the left side of the tumor, with the tumor edges sharply resected and completely dissected. The operation time was 240 min, without thermal ischemia time, and the bleeding volume was about 300 ml. The patient recovered well after the operation, and the postoperative pathological diagnosis was renal abscess.Conclusions:Robot-assisted laparoscopic treatment of horseshoe kidney combined with renal tumor is safe and effective, and has more advantages than traditional laparoscopic surgery. Preoperative CT arteriography or three-dimensional reconstruction examination should be applied to fully evaluate the variant vessels. The surgical access and plan should be decided according to the size and location of the tumor. The variant vessels should be properly handled during operation. The use of endoscopic cutting anastomosis to deal with the isthmus can be more conducive to the surgical operation.

RESUMEN
Band 3 protein is an important channel protein in the erythrocyte membrane which mediates the anion transport process inside and outside the cell membrane,as well as contributes to the maintenance of erythrocyte morphology,and has important physiological functions.However,the distribution state of this protein in the primary cell membrane is not known.Cryo-scanning electron microscopy enables imaging of the surface morphology of biological samples in a near-physiological state.In order to investigate the distribution of band 3 protein on erythrocyte membranes under physiological conditions,the present study utilized 5-nm gold nanoparticles modified with the antibodies to specifically bind to the band 3 protein on human blood erythrocyte membranes and imaged them by cryo-scanning electron microscopy,to obtain distribution of band 3 protein on human blood erythrocyte membranes.The results showed that the membrane proteins on the erythrocyte membranes tended to be clustered and distributed to form ″protein islands″,and band 3 proteins were mainly distributed in these protein islands,which were tightly connected with each other to form several functional microregions to play their respective roles.
RESUMEN
Objective To investigate the distribution characteristics of serum sIgE antibodies against four allergenic protein components of egg white in children with egg allergy,and then clarify the clinical application value of single component-resolved diagnostics of egg allergy.Methods Serum samples from 197 children with egg allergy were collected.The levels of serum sIgE antibodies against four major allergenic protein components of egg white,including ovomucin,ovalbumin,ovotransferrin,and lysozyme,were detected by the light-excited chemiluminescence assay(LiCA),and the distribution characteristics of sIgE antibodies were analyzed.Results The positive rates of serum sIgE antibodies against ovalbumin,ovomucin,ovotransferrin,and lysozyme in 197 chlidren with egg allergy were 77.16%(152/197),70.56%(139/197),35.02%(69/197),and 18.27%(36/197),respectively.The positive rate of serum sIgE antibody against both ovomucin and ovalbumin was 30.45%.There was a weak correlation between the levels of sIgE antibodies against egg and the cumulative levels of sIgE antibodies against four allergenic protein components(r=0.266 8,P<0.05).There were signifi-cant individual differences in the levels of serum sIgE antibodies against four allergenic protein components of egg white in the children with egg allergy.Conclusion There is individual heterogeneity in the levels of serum sIgE antibodies against four components of egg white in the children with egg allergy.The detection of sIgE antibodies against egg white components can distinguish different forms of egg allergies,which is of great value for the accurate diagnosis and precise desensitization of children's egg allergy.
RESUMEN
BACKGROUND:As a dominant breed pig in southwest China,the southern Yunnan small-ear pig has been widely used as an experimental animal in the basic research of other disciplines,but there are still no reports on its application in anterior cruciate ligament reconstruction. OBJECTIVE:To establish a large animal model of the southern Yunnan small-ear pig with anterior cruciate ligament with autologous Achilles tendon was established. METHODS:Twenty adult female Yunnan small-ear pigs were equally randomized into two groups.In the autologous Achilles tendon group,the right knee anterior cruciate ligament was reconstructed with autologous Achilles tendon as a graft,while in the sham-operated group,a similar operation was performed on the right knee without any treatment of the anterior cruciate ligament.General conditions of each pig were observed and recorded before and 12 months after surgery.Ligaments and grafts were taken for gross observation and MAS scoring.Hematoxylin-eosin staining was performed to observe morphological characteristics of ligaments.The staining and arrangement of type I and type Ⅲ collagen were evaluated by immunohistochemistry.Transmission electron microscopy was used to observe the type,size,diameter,ratio,and distribution of collagen fibers in ligaments. RESULTS AND CONCLUSION:All animals had normal diet and activity,good wound healing,no obvious inflammatory reaction,no local purulent infection,and no significant changes in mental and urinary conditions compared with those before surgery.The reconstructed cruciate ligament of the knee was intact,with no stiffness and normal range of motion.Both the anterior drawer and Lachman tests were negative.Gross observation of the graft:12 months after surgery,the grafts was in good position,with good integrity,obvious tension,ligament color close to the original anterior cruciate ligament,and complete surface synovial coverage.Most of the intraarticular ligaments in the autologous Achilles tendon group were defined as MAS I type and a few were defined as MAS Ⅱ type.In the sham-operated group,the intraarticular ligament was defined as MAS I type.Hematoxylin-eosin staining indicated that,12 months after surgery,collagen fibers in the autologous Achilles tendon group began to appear bundled,isotropic,and uniformly arranged,with more obvious isotropic corrugations,and the nuclei were mainly linear or spindle-shaped,which were similar to those in normal anterior cruciate ligament tissue of the sham-operated group.Immunohistochemistry results indicated that,12 months after surgery,there was a higher expression of type I collagen and significantly less expression of type Ⅲ collagen in the reconstructed anterior cruciate ligament in the autologous Achilles tendon group.The degree of type I and type Ⅲ staining was similar in the two groups.Under the transmission electron microscope,the diameter,arrangement and density of collagen fibers in the reconstructed anterior cruciate ligament of the autologous Achilles tendon group were similar to those of the original anterior cruciate ligament at 12 months after surgery,indicating that the ligament remodeling process had been basically completed in the autologous Achilles tendon group at 12 months after surgery.Through a comprehensive evaluation of animal general conditions,ligament general view,MAS score,hematoxylin-eosin staining,immunohistochemistry,and transmission electron microscopy observation,we successfully established a large animal model of anterior cruciate ligament reconstruction using autogenous Achilles tendon in southern Yunnan small-ear pigs,with good morphological,histological and ultrastructural results.
RESUMEN
BACKGROUND:Our previous studies found that the polypeptide of Cornus cervi Colla can promote bone growth,which has a good application prospect in the treatment of bone diseases.However,how Cornus cervi Colla works in the body and the principle are not clear. OBJECTIVE:To study the in vivo distribution and tracing of Cornus cervi Colla using fluorescence labeling and tracer technique. METHODS:Cornus cervi Colla was fluorescently labeled using fluorescein isothiocyanate,and the labeling results were detected by fluorescence imaging and UV spectral scanning.Successfully labeled Cornus cervi Colla was injected into mice by gavage,and the absorption of Cornus cervi Colla into blood was detected by laser confocal microscopy,and the distribution of Cornus cervi Colla in mice was detected by small animal in vivo imager.The distribution of Cornus cervi Colla in the mice was detected by laser confocal microscopy.Samples were taken from serum and bone at the time of the strongest fluorescence,and gel electrophoresis was carried out on serum and bone tissue protein solutions,and the components of Cornus cervi Colla absorbed into target organs were determined by secondary mass spectrometry. RESULTS AND CONCLUSION:The fluorescent markers were successfully separated by dextran gel chromatography,and the fluorescence imaging and ultraviolet spectrum scanning proved that the labeling was successful,and the fluorescence substitution degree of FITC-labeled Cornus cervi Colla was 0.953%.The fluorescence intensity of the components of Cornus cervi Colla in the blood showed that Cornus cervi Colla was most distributed in serum after oral administration for 2 hours.The fluorescence images of mice at different times were the same as those of bilateral femur and tibia,indicating that Cornus cervi Colla could play a role by entering the bone.Compared with UniProt database,secondary mass spectrometry showed that the peptide was a characteristic fragment of decorin.It is proved that decorin in Cornus cervi Colla can enter the bone to play a therapeutic role.
RESUMEN
Objective:To explore the value of nomogram based on dual-layer detector spectral CT quantitative parameters and conventional CT feature in evaluating high-grade pattern (HGP) of pulmonary invasive non-mucinous adenocarcinoma.Methods:This study was a case-control study. A total of 71 patients with pathologically confirmed pulmonary invasive non-mucinous adenocarcinoma in the First Affiliated Hospital of Soochow University from February 2022 to May 2023 were retrospectively enrolled, which were divided into HGP and non-HGP groups according to pathological results. Conventional CT features were analyzed, including size, shape, density, internal signs, margins, and pleural retraction. The iodine concentration (IC), electron density (ED), and normalized iodine concentration (NIC) of the lesions in both the arterial phase (AP) and venous phase (VP) were measured. Differences between the two groups were analyzed using independent sample t-test, Mann-Whitney U test, or χ2 test. Multivariate logistic regression analysis was used to select the independent influencing factors of HGP in pulmonary invasive non-mucinous adenocarcinoma, and the conventional CT feature model, the spectral CT quantitative parameter model, and the combined model were constructed and expressed in a nomogram. The area under the curve (AUC) of receiver operating characteristic curve was used to assess the performance of each model, and was compared by DeLong test. Decision curves (DCA) was used to assess the clinical net benefit of the models. Results:There were significant differences between HGP group and non-HGP group in terms of density, lobulation, spiculation, IC AP, IC VP, NIC AP, ED AP and ED VP (all P<0.05). The multivariate logistic regression analysis showed that the solid nodule ( OR=15.452, 95% CI 4.246-56.235, P<0.001), lobulation ( OR=7.069, 95% CI 1.618-30.883, P=0.009), ED AP( OR=1.183, 95% CI 1.064-1.315, P=0.002) and IC VP ( OR=0.231, 95% CI 0.072-0.744, P=0.014) were independent influencing factors for predicting HGP in pulmonary invasive non-mucinous adenocarcinoma. The AUC of the conventional CT feature model, spectral CT quantitative parameter model, and the combined model were 0.835, 0.890, and 0.915, respectively. The AUC of the combined model was better than that of the conventional CT feature model ( Z=2.67, P=0.008). The DCA analysis demonstrated that the nomogram had higher clinical net benefit than the conventional CT feature model. Conclusions:The nomogram based on the quantitative parameters of dual-layer detector spectral CT and conventional CT features have favorable diagnostic efficacy in predicting HGP in pulmonary invasive non-mucinous adenocarcinoma, and can be used as a reliable tool for non-invasive diagnosis of HGP before surgery.
RESUMEN
Objective:To establish a single-tube, one-step method for detecting and identifying 16 high-risk human papillomavirus (HR-HPV) subtypes (HPV16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66, 68, 73, 82) and genotyping p53 (rs1042522) and RB1 (rs3092905) in cervical cells, using high-throughput two-dimensional PCR (2D-PCR) technology. Methods:Applied Research. Specific primers were designed according to the DNA sequences of the 16 different HR-HPV subtypes, p53, and RB1 genes, with the target genes p53 and RB1 serving as internal references to assess the success of sample collection and PCR amplification. In three fluorescent detection channels, upstream primers labeled with corresponding tags were used for different HR-HPV subtypes, p53, and RB1, constructing a comprehensive 2D-PCR detection system. Using this method, 804 cervical brush samples collected from the gynecology outpatient department of Changzhou First People′s Hospital from December 2022 to August 2023 were tested. The test results were compared for consistency with PCR-reverse dot blot assay, flow cytometric fluorescence hybridization assay, and single-plex real-time quantitative PCR assay, respectively. Meanwhile, the genotypes of p53 and RB1 were detected using Sanger sequencing. The Kappa test was applied to determine the consistency between 2D-PCR method and other methods. Results:2D-PCR accurately discriminated and identified the genotypes of 16 HR-HPV types and p53, RB1 through characteristic melting valleys in the FAM, HEX, and Alexa Fluor568 channels. 2D-PCR showed high consistency with PCR-reverse dot blot assay, with a Kappa value of 0.699, even higher consistency with flow cytometric fluorescence hybridization assay, with a Kappa value of 0.793, and the highest consistency with single-plex quantitative PCR, with a Kappa value of 0.880 (95% CI 0.862-0.907). Using Sanger sequencing as the gold standard, the accuracy of 2D-PCR method in detecting p53 and RB1 genotypes is 100%. The distribution frequencies of the three genotypes (G/G, G/C, and C/C) at the p53 rs1042522 locus were 32.09% (258/804), 49.88% (401/804) and 18.03% (145/804), respectively, while all detected genotypes at the RB1 rs3092905 locus were A/A. Conclusion:This study successfully developed a 2D-PCR method for the identification and genotyping of high-risk human papillomavirus types and related tumor suppressor genes p53 and RB1 for cervical cancer.
RESUMEN
By consulting the ancient and modern literature, the name, origin, quality evaluation, harvesting and processing methods of Curculiginis Rhizoma(CR) were systematically combed and verified, in order to provide a basis for the development and utilization of famous classical formulas containing CR. The results of herbal textual research showed that the name Xianmao was first recorded in Leigong Paozhilun, the name of CR was used in all dynasties and this name came from its efficacy and morphological characteristics, the mainstream source for CR of the past dynasties was the rhizome of Curculigo orchioides or C. capitulata, since modern times, C. orchioides has been the main source of commodities. In ancient times, most of the places of origin of the description were the western regions and southwest China, while in modern times, Sichuan and Guizhou were regarded as genuine places. Since modern times, its quality has been summarized as the best with thick roots, firm texture and black-brown surface, the harvesting and processing methods recorded in the past dynasties are mainly sun drying after harvest in the second, eighth and ninth months of the lunar calendar, and most of them are harvested in autumn and winter in modern times. In ancient times, there were many processing methods of CR, mainly in processing with rice swill, while in modern times, stir-frying with wine was the main processing method. The nature, taste, meridian tropism, functions and indications of CR are basically consistent from ancient to modern times, the taboos for taking are to avoid iron, cow's milk, and beef. Although there are some differences in the understanding of the toxicity of CR in the past dynasties, most of the materia medica are clear that it has a certain toxicity. Based on the research conclusion, it is suggested that the rhizome of C. orchioides of Lycoris family should be used as its source in the famous classical formulas, and the corresponding processing method should be selected according to the processing requirements in the formulas, while the raw products is recommended to be selected as medicine if the processing requirement is not specified.
RESUMEN
【Objective】 To explore the prognostic impact and clinical application value of therapeutic plasma exchange(TPE) intervention timing and liver injury periodization in patients with exertional heat stroke(EHS). 【Methods】 Data of 127 EHS patients from the First Medical Center of the General Hospital of the People′s Liberation Army from January 2011 to December 2023 were collected, then divided into the death group and the survival group based on therapeutic outcomes and into 5 stages according to the dynamic changes of ALT, AST, TBIL and DBIL. According to propensity score matching analysis, 11 patients in the survival group and 12 patients in the death group were included in the statistical analysis, and 20 of them were treated with TPE. The changes in indicators and clinical outcomes before and after TPE were observed, in order to evaluate the impact of intervention timing on prognosis. 【Results】 Among the 23 patients, 14 had no liver injury or could progress to the repair phase, resulting in 3 deaths(with the mortality rate of 21.43%), while 9 patients failed to progress to the repair phase, resulting in 9 deaths(with the mortality rate of 100%), with significant differences(P<0.05). The mortality rate of the first TPE intervention before the third stage of liver injury was 23.08%(3/13), while that of intervention after reaching or exceeding the third stage was 85.71%(6/7), and the difference was statistically significant(P<0.05). 【Conclusion】 TPE should be executed actively in EHS patients combined with liver injury before the third phase to lock its pathological and physiological processes, thereby improving prognosis and reducing mortality.
RESUMEN
【Objective】 To investigate the clinical efficacy of preoperative therapeutic plasma exchange(TPE) in preventing acute rejection after ABO incompatible kidney transplantation(ABOi-KT). 【Methods】 Nine patients with ABOi-KT who were admitted to the renal transplant department of our hospital from April 2022 to April 2024 were retrospectively analyzed. They received a total of 28 TPEs before kidney transplantation, and the treatment plan was summarized as follows: The proportion of the substitute fluid, as well as the frequency and volume of TPE were determined based on the patient′s ABO blood group system antibody titer, gender, height, weight, hematocrit and other indicators upon admission. The patient′s relevant laboratory indicators, including hemoglobin, platelets, leukocytes, coagulation function, total protein, albumin, globulin, A/G, creatinine and urea nitrogen upon admission and after TPE were monitored and statistically analyzed. After transplantation, changes in renal function indicators such as ABO blood group system antibody titers, creatinine and urinary excretion were observed, and clinical symptoms of acute rejection, such as swelling, pain and edema in the transplanted kidney area were observed. 【Results】 Nine ABOi-KT patients had an average of about 3 TPEs before transplantation surgery, with an average total volume of approximately 2 500 mL to 3 500 mL per TPE, or approximately about 1.01 to 1.16 plasma volume (PV). After multiple TPEs, pre-transplantation antibody titers decreased by an average of 3 times compared to before TPE. There were no statistically significant differences in Hb, PLT, PT, PTA, INR, TBil, ALB, Cr and BUN (P>0.05), while statistically significant differences were found in WBC, APTT, Fbg, TP, GLB and A/G (P<0.05). After surgery, the creatinine level of 9 patients dropped to approximately 100 to 140 μmol/L, the urine output was normal, and the urine protein dropped to weakly positive or negative values. None of the nine patients experienced acute rejection. 【Conclusion】 TPE can effectively reduce the level of ABO blood group antibody and prevent the occurrence of acute rejection in ABOi-KT patients.
RESUMEN
【Objective】 To review the occurrence of allergic reactions during therapeutic plasma exchange (TPE) and to explore the risk factors of TPE allergic reactions. 【Methods】 The clinical data of 929 patients treated with TPE using plasma components by the Department of Transfusion Medicine in our medical center from 2018 to 2023 were collected. The influencing factors of allergic reactions were analyzed by univariate analysis, and the independent risk factors of allergic reactions were analyzed by logistic multivariate regression analysis. 【Results】 A total of 4 071 TPEs were performed in 929 patients.Among them, 198 patients (21.31%) experienced 349 times (8.57%) of allergic reactions, with the incidence of grade Ⅰ, Ⅱ and Ⅲ allergic reactions of 16.33%, 81.38% and 2.29%, respectively, and no deaths. The univariate analysis showed that the patient′s age, allergy history, diagnosis of immune-related diseases, ICU admission, plasma consumption, total blood volume, maximum blood flow rate and combined use of albumin were related to the occurrence of allergic reactions (P<0.05). Multivariate regression analysis showed that young patients, a history of allergy, immune-related diseases and non-ICU patients were prone to allergic reactions in TPE, but the treatment options of TPE such as substitute fluid category, plasma consumption and blood flow rate were not related to the occurrence of allergic reactions. 【Conclusion】 There are significant individual differences in the occurrence of allergic reactions for TPE, and young age, history of allergies, immune-related diseases and non-ICU patients are risk factors for allergic reactions in TPE. Identifying patients with risk factors before TPE treatment and giving corresponding preventive measures can reduce the incidence of allergic reactions.
RESUMEN
Objective: To investigate the clinical characteristics of induced labor in twin pregnancy and the related factors of induced labor failure. Methods: The clinical data of twin pregnant women who underwent induced labor in Peking University Third Hospital from January 2016 to December 2022 were retrospectively analyzed. According to whether they had labor or not after induction, pregnant women were divided into the success group (pregnant women who had labor after induction, 72 cases) and the failure group (pregnant women who did not have labor after induction, 30 cases). Logistic regression was used to analyze the related factors of induction failure in twin pregnant women. Results: The parity and cervical Bishop score in the failure group were significantly lower than those in the success group, while the proportion of dichorionic diamniotic twins, assisted reproductive technology pregnancy and cervical Bishop score <6, postpartum hospital stay and total hospital stay in the failure group were significantly higher than those in the success group (all P<0.05). The proportion of induced labor by artificial rupture of membranes ± oxytocin intravenous infusion in the success group was 72.2% (52/72), which was significantly higher than that in the failure group (46.7%, 14/30; P=0.030). There were no significant differences between the two groups in the gestational age at delivery, the incidence of severe postpartum hemorrhage and blood transfusion, the amount of postpartum hemorrhage, the neonatal weight of two fetuses, the incidence of neonatal asphyxia, and the proportion of neonates admitted to the neonatal intensive care unit (all P>0.05). There were no severe perineal laceration and hysterectomy in all pregnant women. Multivariate logistic regression analysis showed that primipara (OR=3.064, 95%CI: 1.112-8.443; P=0.030) and cervical Bishop score <6 (OR=5.208, 95%CI: 2.008-13.508; P=0.001) were the independent risk factors for induction failure in twin pregnancy. Conclusions: Elective induction of labor in twin pregnancy is safe and feasible. It is helpful to improve the success rate of induction of labor by strictly grasping the timing and indications of termination of pregnancy, choosing the appropriate method of induction according to the condition of the cervix, and actively promoting cervical ripening .

Abstract@#Flexibleis an important classification of flat foot. Flatfoot occurs due to a variety of reasons and causes the medial longitudinal arch to collapse or disappear. However, many children still do not develop a normal foot arch as the grow, and a failure to intervene in a timely manner will greatly harm a child s normal mobility development. Timely detection and intervention are the key to improve the prognosis. There is a lack of uniform quantitative criteria for the diagnosis of flexible flatfoot. Currently, the commonly used diagnostic methods include physical examination, foot printing, plantar pressure test and imaging examination. This article reviews the risk factors, diagnosis, prevention and treatment of Flexible Flatfoot.
RESUMEN
Background@#In this study, we prepared and evaluated an injectable poloxamer (P407) hydrogel formulation for intratympanic (IT) delivery of dexamethasone (DEX). @*Methods@#DEX-loaded P407 hydrogels were characterized in terms of thermogelation, drug loading capacities, particle size, and drug release. The in vivo toxicity and drug absorption of the DEX-loaded P407 formulation after IT injection were evaluated using an animal model by performing histopathological analysis and drug concentration measurements. @*Results@#The P407 hydrogel effectively solubilized hydrophobic DEX and demonstrated a sustained release compared to the hydrophilic DEX formulation. The in vivo study showed that the hydrogel formulation delivered considerable drug concentrations to the inner ear and displayed a favorable safety profile without apparent cytotoxicity or inflammation. @*Conclusion@#P407 hydrogel can be useful as an injectable inner ear delivery formulation for hydrophobic drugs due to their biocompatibility, drug-solubilizing capacity, thermogelation, and controlled release.
RESUMEN
BACKGROUND/OBJECTIVES@#Inflammation is often associated with chronic diseases, and numerous studies suggest that certain foods can modulate inflammatory status. This study aimed to assess the impact of intensive nutrition education on glycemic control and inflammation in patients with diabetes mellitus using the Korean food-based index of dietary inflammatory potential (FBDI). @*SUBJECTS/METHODS@#A total of 120 patients (male: 70, 58.3%) were randomly divided into two groups of 60 each, to be given intensive nutritional education (IE) and basic nutritional education (BE), respectively. As part of the nutrition education intervention, basic diabetesrelated nutrition education was provided to both groups initially. In addition, the IE was provided two face-to-face nutrition education sessions based on FBDI over six months, and text transmissions were made at least eight times. We surveyed the anthropometric measurements, biochemical indicators, inflammatory markers, and dietary intake before and after the interventions. We analyzed the effects of the intensive nutrition education using the t-test, χ 2 test and paired t-test. @*RESULTS@#Of the subjects, 76.7% (46/60) of the IE and 86.7% (52/60) of the BE completed the study. The results of the paired t-test to evaluate the effectiveness of nutrition education using FBDI showed that high density lipoprotein-cholesterol increased significantly from 42.6 mg/dL before intervention to 49.2 mg/dL after intervention (P = 0.009), tumor necrosis factor-α significantly decreased from 1.25 pg/mL before intervention to 1.11 pg/mL after intervention (P =.012) in the IE. Also, glycated hemoglobin decreased from 8.0% to 7.5% in the IE but increased from 7.4% to 7.7% in the BE, and the differences between the groups were significant (P= 0.008). @*CONCLUSION@#These findings suggest that providing intensive FBDI-based education on antiinflammatory foods positively affected glycemic control and inflammatory status in diabetes patients. Therefore, practical dietary plans using FBDI should be considered for diabetes patients to prevent increased inflammation.

Objective To predict the potential suitable habitat of Haemaphysalis concinna in Heilongjiang Province under different climatic scenarios. Methods The geographic locations of ticks in Heilongjiang Province from 1980 to 2022 were captured from literature review and field ticks monitoring data from Harbin Center for Disease Control and Prevention in Heilongjiang Province, and the tick distribution sites with spatial correlations were removed using the software ArcGIS 10.2. The environment data under historical climatic scenarios from 1970 to 2000 and the climatic shared socioeconomic pathways (SSP) 126 scenario model from 2021 to 2040 and from 2041 to 2060 were downloaded from the WorldClim website, and the elevation (1 km, 2010), population (1 km grid population dataset of China, 2010) and annual vegetation index (1 km, 2010) data were downloaded from the Resource and Environmental Science and Data Center, Institute of Geographical Sciences and Natural Resources, Chinese Academy of Sciences. The contribution of environmental factors to H. concinna distribution was evaluated and environmental variables were screened using the software MaxEnt 3.4.1 and R package 4.1.0, and the areas of suitable habitats of H. concinna and changes in center of gravity were analyzed using the maximum entropy model in Heilongjiang Province under different climatic scenarios. In addition, the accuracy of the maximum entropy model for prediction of H. concinna distribution was assessed using the area under curve (AUC) of the receiver operating characteristic curve. Results A total of 79 H. concinna distribution sites and 24 environmental variables were collected, and 70 H. concinna distribution sites and 9 environmental factors that contributed to distribution of the potential suitable habitats of H. concinna in Heilongjiang Province were screened. The three most significant contributing factors included precipitation seasonality, annual precipitation, and mean temperature of the driest quarter, with cumulative contributions of 60.7%. The total area of suitable habitats of H. concinna was 29.05 × 104 km2 in Heilongjiang Province under historical climatic scenarios, with the center of gravity of suitable habitats located at (47.31° N, 129.16° E), while the total area of suitable habitats of H. concinna reduced by 0.97 × 104 km2 in Heilongjiang Province under the climatic SSP126 scenario from 2041 to 2060, with the center of gravity shifting to (47.70° N, 129.28° E). Conclusions The distribution of suitable habitats of H. concinna strongly correlates with temperature and humidity in Heilongjiang Province. The total area of potential suitable habitats of H. concinna may appear a tendency towards a decline with climatic changes in Heilongjiang Province, and high-, medium- and low-suitable habitats may shift.
RESUMEN
@#Objective To investigate the clinical safety and feasibility of thoracic sympathectomy in the treatment of palmar hyperhidrosis based on ambulatory surgery. Methods A retrospective analysis of 74 patients who underwent thoracoscopic sympathectomy in the Department of Thoracic Surgery of the First People's Hospital of Yunnan Province from January 2017 to April 2021 was performed, including 35 males and 39 females aged 12-38 (21.32±4.13) years. Patients were divided into two groups according to different treatments. There were 34 patients in a control group (adopting traditional surgery), and 40 patients in an observation group (adopting ambulatory surgery). The clinical effects of the two groups were compared. Results No massive bleeding, conversion to thoracotomy, postoperative pneumo-thorax or severe pneumonia occured in all patients. Univariate analysis of intraoperative indexes showed that the two groups had no statistical difference in total hospitalization cost, operation time, anesthesia time or postoperative waiting time (P>0.05). The amount of intraoperative blood loss in the observation group was less than that in the control group (P<0.05). The time of postoperative out of bed and recovery of walking capacity and the incidence of electrolyte disturbance in the observation group were shorter or lower than those in the control group (P<0.05). There was no statistical difference in white blood count, neutrophils count or postoperative 24 h pulse oxygen saturation fluctuation peak between the two groups (P>0.05). Conclusion Based on the optimized diagnosis and treatment model, thoraco-scopic sympathectomy with laryngeal mask airway which is performed during ambulatory surgery, is feasible and worth popularizing in thoracic surgery.
RESUMEN
BACKGROUND@#LY01005 (Goserelin acetate sustained-release microsphere injection) is a modified gonadotropin-releasing hormone (GnRH) agonist injected monthly. This phase III trial study aimed to evaluated the efficacy and safety of LY01005 in Chinese patients with prostate cancer.@*METHODS@#We conducted a randomized controlled, open-label, non-inferiority trial across 49 sites in China. This study included 290 patients with prostate cancer who received either LY01005 or goserelin implants every 28 days for three injections. The primary efficacy endpoints were the percentage of patients with testosterone suppression ≤50 ng/dL at day 29 and the cumulative probability of testosterone ≤50 ng/dL from day 29 to 85. Non-inferiority was prespecified at a margin of -10%. Secondary endpoints included significant castration (≤20 ng/dL), testosterone surge within 72 h following repeated dosing, and changes in luteinizing hormone, follicle-stimulating hormone, and prostate specific antigen levels.@*RESULTS@#On day 29, in the LY01005 and goserelin implant groups, testosterone concentrations fell below medical-castration levels in 99.3% (142/143) and 100% (140/140) of patients, respectively, with a difference of -0.7% (95% confidence interval [CI], -3.9% to 2.0%) between the two groups. The cumulative probabilities of maintaining castration from days 29 to 85 were 99.3% and 97.8%, respectively, with a between-group difference of 1.5% (95% CI, -1.3% to 4.4%). Both results met the criterion for non-inferiority. Secondary endpoints were similar between groups. Both treatments were well-tolerated. LY01005 was associated with fewer injection-site reactions than the goserelin implant (0% vs . 1.4% [2/145]).@*CONCLUSION@#LY01005 is as effective as goserelin implants in reducing testosterone to castration levels, with a similar safety profile.@*TRIAL REGISTRATION@#ClinicalTrials.gov, NCT04563936.
