ABSTRACT

AIM: To evaluate the efficacy of phacoemulsification with intraocular lens implantation(PEI)combined with goniosynechialysis(GSL)and goniotomy(GT)under direct vision with gonioscope in the treatment of advanced primary angle-closure glaucoma(PACG)combined with cataract.METHODS: Retrospective case series study. A total of 62 patients(65 eyes)with advanced PACG combined with cataract who were treated in the Second Hospital of Anhui Medical University from December 1, 2021 to March 31, 2023 were enrolled, and they were divided into two groups according to different surgical methods. The control group(32 cases, 33 eyes)received PEI+GSL, whereas the observation group(30 cases, 32 eyes)received PEI+GSL+GT. The intraocular pressure(IOP), best corrected visual acuity(BCVA)and the number of anti-glaucoma medications of the two groups before surgery and at 1 d, 1 wk, 1, 3, and 6 mo after surgery were evaluated. In addition, the visual field, cup-to-disc ratio(C/D), angle open range, anterior chamber depth, and average thickness of retinal nerve fiber layer(RNFL)were evaluated before and 6 mo after surgery.RESULTS: There were significant differences in IOP and lowering range of average IOP at 6 mo between the PEI+GSL+GT group(16.68±2.65, 11.12±8.53 mmHg)and the PEI+GSL group(18.71±2.51, 8.32±4.17 mmHg; P<0.05), and there was no difference in the rate of IOP reduction(44.57%±21.79% and 35.20%±17.94%, P>0.05). The number of anti-glaucoma medications, BCVA, anterior chamber depth, and angle closure range were improved in the two groups at 6 mo after operation(all P<0.01). The number of medication reductions and the range of angle opening at 6 mo after surgery in the PEI+GSL+GT group were significantly higher than those in the PEI+GSL group(P<0.05), and there was no difference in the other indicators between the two groups(all P>0.05). There was no difference in the mean deviation of visual field, C/D and average thickness of RNFL between the two groups at 6 mo after operation compared with those before operation(all P>0.05). The complete surgery success rate of the PEI+GSL+GT group was 81%(26/32), and the conditional success rate was 94%(30/32); while those rates of the PEI+GSL group were 58%(19/33)and 76%(25/33), respectively. There were statistical significance in the success rate of surgery between the two groups(complete success rate χ2=4.275, P=0.039; conditional success rate χ2=4.040, P=0.044). No vision-threatening complications and another surgery occurred in either group.CONCLUSION: The study showed that for patients with advanced PACG with cataract, PEI+GSL+GT is more effective than PEI+GSL.

ABSTRACT

Objective@#We aimed to investigate whether 2-[ 18F]fluoro-2-deoxy-D-glucose positron emission tomography/computed tomography (2-[ 18F]FDG PET/CT) can aid in evaluating the risk of malignancy in ampullary tumors detected by endoscopy. @*Materials and Methods@#This single-center retrospective cohort study analyzed 155 patients (79 male, 76 female; mean age, 65.7 ± 12.7 years) receiving 2-[ 18F]FDG PET/CT for endoscopy-detected ampullary tumors 5–87 days (median, 7 days) after the diagnostic endoscopy between June 2007 and December 2020. The final diagnosis was made based on histopathological findings. The PET imaging parameters were compared with clinical data and endoscopic features. A model to predict the risk of malignancy, based on PET, endoscopy, and clinical findings, was generated and validated using multivariable logistic regression analysis and an additional bootstrapping method. The final model was compared with standard endoscopy for the diagnosis of ampullary cancer using the DeLong test. @*Results@#The mean tumor size was 17.1 ± 7.7 mm. Sixty-four (41.3%) tumors were benign, and 91 (58.7%) were malignant. Univariable analysis found that ampullary neoplasms with a blood-pool corrected peak standardized uptake value in earlyphase scan (SUVe) ≥ 1.7 were more likely to be malignant (odds ratio [OR], 16.06; 95% confidence interval [CI], 7.13–36.18;P < 0.001). Multivariable analysis identified the presence of jaundice (adjusted OR [aOR], 4.89; 95% CI, 1.80–13.33; P = 0.002), malignant traits in endoscopy (aOR, 6.80; 95% CI, 2.41–19.20; P < 0.001), SUVe ≥ 1.7 in PET (aOR, 5.43; 95% CI, 2.00–14.72; P < 0.001), and PET-detected nodal disease (aOR, 5.03; 95% CI, 1.16–21.86; P = 0.041) as independent predictors of malignancy. The model combining these four factors predicted ampullary cancers better than endoscopic diagnosis alone (area under the curve [AUC] and 95% CI: 0.925 [0.874–0.956] vs. 0.815 [0.732–0.873], P < 0.001). The model demonstrated an AUC of 0.921 (95% CI, 0.816–0.967) in candidates for endoscopic papillectomy. @*Conclusion@#Adding 2-[ 18F]FDG PET/CT to endoscopy can improve the diagnosis of ampullary cancer and may help refine therapeutic decision-making, particularly when contemplating endoscopic papillectomy.

ABSTRACT

Background@#Glove reuse poses risks, as chemicals can persist even after cleaning. Decontamination methods like thermal aeration, recommended by US OSHA, vary in effectiveness. Some studies show promising results, while others emphasize the importance of considering both permeation and tensile strength changes. This research advocates for informed glove reuse, emphasizing optimal thermal aeration temperatures and providing evidence to guide users in maintaining protection efficiency. @*Methods@#The investigation evaluated Neoprene and Nitrile gloves (22 mils). Permeation tests with toluene and acetone adhered to American Society for Testing Materials (ASTM) F739 standards. Decontamination optimization involved aeration at various temperatures. The experiment proceeded with a maximum of 22 re-exposure cycles. Tensile strength and elongation were assessed following ASTM D 412 protocols. Breakthrough time differences were statistically analyzed using t-test and ANOVA. @*Results@#At room temperature, glove residuals decreased, and standardized breakthrough time (SBT)2 was significantly lower than SBT1, indicating reduced protection. Higher temperature decontamination accelerated residual removal, with ΔSBT (SBT2/SBT1) exceeding 100%, signifying restored protection. Tensile tests showed stable neoprene properties postdecontamination. Results underscore thermal aeration's efficacy for gloves reuse, emphasizing temperature's pivotal role. Findings recommend meticulous management strategies, especially post-breakthrough, to uphold glove-protective performance. @*Conclusions@#Thermal aeration at 100°C for 1 hour proves effective, restoring protection without compromising glove strength. The study, covering twenty cycles, suggests safe glove reuse with proper decontamination, reducing costs significantly. However, limitations in chemical-glove combinations and exclusive focus on specific gloves caution against broad generalization. The absence of regulatory directives on glove reuse highlight the importance of informed selection and rigorous decontamination validation for workplace safety practices.

ABSTRACT

It has become an industry consensus that self-assembled nanoparticles (SAN) are formed by molecular recognition of chemical components in traditional Chinese medicine during the decoction process. The insoluble components in the decoction are mostly in the form of nanoparticles, which can improve the problem of poor water solubility. However, the transfer rate of these insoluble components in the decoction is still very low, which limits the efficacy of the drug. This study aimed to refine the traditional decoction self-assembly phenomenon. The self-assembled nanoparticles were constructed by micro-precipitation method (MP-SAN), and characterized by particle size, zeta potential, stability index and morphology. The formation of MP-SAN and alterations in related physicochemical properties were evaluated using modern spectroscopic and thermal analysis techniques. The quality value transmitting pattern of lignan components within the MP-SAN was assessed via high performance liquid chromatography (HPLC). The MP-SAN showed sphere-like structure with uniform morphology, particle size of (245.3 ± 3.2) nm, polydispersity index (PDI) of (0.13 ± 0.03), zeta potential of (-48.9 ± 5.9) mV and stability index (SI) of (86.05% ± 2.27%). Comprehensive analyses using ultraviolet visible spectroscopy, Fourier transform infrared spectroscopy, differential scanning calorimetry, and other techniques confirmed molecular recognition between the decoction and ethanol extraction, leading to electron rearrangement under the influence of non-covalent bonding. This resulted in the formation of nanoparticles possessing superior thermal stability. As determined by HPLC, the encapsulation rates of the index components in the MP-SAN were all greater than 75% (dehydrodiconiferyl alcohol: 77.00%; herpetolide A: 78.57%; herpetrione: 94.53%), and the transfer rates were all higher than 65% (dehydrodiconiferyl alcohol: 96.01%; herpetolide A: 67.86%; herpetrione: 65.55%), which were 1.34, 1.38 and 4.81 times compared with those of the traditional decoction. In summary, this study successfully constructed the MP-SAN based on micro-precipitation method to achieve high transfer rate and high encapsulation rate of insoluble components in docoction, which provides a pharmaceutics idea for the efficient utilization of pharmacodynamic substance basis of traditional Chinese medicine.

ABSTRACT

Tibet orbivirus (TIBOV) was identified as a novel orbivirus in 2014. Antibodies against TIBOV were detected in cattle, Asian buffalo, and goats, while all the sequenced TIBOV strains were isolated from mosquitos and Culicoides. The known TIBOV strains have been classified into four putative serotypes. In this study, two TIBOV strains isolated from Culicoides spp. in Shizong County of Yunnan Province, China, were fully sequenced. The phylogenetic analysis of outer capsid protein 2 (VP2) indicated that these two viral strains belong to two novel putative serotypes of TIBOV. The updated putative serotypes may help in an investigation of the distribution and virulence of TIBOV.

ABSTRACT

Purpose@#This study aimed to explore the impact of ABL1–tyrosine kinase inhibitors (TKIs) adherence on the survival of chromosome-positive (Ph+) acute lymphoblastic leukemia (ALL) children and clarify the potential predictors of patients’ prognosis from TKIs intake practices. @*Materials and Methods@#Ninety newly diagnosed Ph+ ALL patients who received TKIs were enrolled. We collected the baseline characteristics and adverse events in all children; moreover, TKIs adherence was measured by an eight-item Morisky medication adherence scale (MMAS-8). Progression-free survival (PFS) and overall survival (OS) analysis were performed, and risk factors for PFS and OS were evaluated. @*Results@#Among all patients, 69 cases were regarded as adherers, while 21 were non-adherers. The median duration of TKIs interruption was significantly prolonged in the non-adherence group than in the adherence group (13 [0-101] vs. 56 [11-128], p < 0.001). Additionally, dose reduction occurred in 55.2% of non-adherers versus 23.0% of adherers (p=0.002). The PFS and OS in adherers were significantly higher versus non-adherers (p=0.020 and p=0.039). MMAS-8 score was an independent risk factor for PFS (p=0.010) and OS (p=0.031). Among non-adherers, the median OS was only 23.1% (4.2%-42%) in patients aged ≤ 10 years versus 54.4% (38.8%-70%) in adolescents. Most of the patients who experienced TKIs non-adherence suffered pancytopenia. @*Conclusion@#TKIs adherence during treatment significantly influenced the survival of pediatric Ph+ ALL patients, and non-adherers with age ≤ 10 years were more vulnerable to TKIs disruption. The cumulative TKIs dose should be especially emphasized to patients with age ≤ 10 years, which may result in an inferior achievement of relevant treatment milestones.

ABSTRACT

Since Curcumae Radix decoction pieces have multiple sources, it is difficult to distinguish depending on traditional cha-racters, and the mixed use of multi-source Curcumae Radix will affect its clinical efficacy. Heracles Neo ultra-fast gas phase electronic nose was used in this study to quickly identify and analyze the odor components of 40 batches of Curcumae Radix samples from Sichuan, Zhejiang, and Guangxi. Based on the odor fingerprints established for Curcumae Radix decoction pieces of multiple sources, the odor components was identified and analyzed, and the chromatographic peaks were processed and analyzed to establish a rapid identification method. Principal component analysis(PCA), discriminant factor analysis(DFA), and soft independent modeling cluster analysis(SIMCA) were constructed for verification. At the same time, one-way analysis of variance(ANOVA) combined with variable importance in projection(VIP) was employed to screen out the odor components with P<0.05 and VIP>1, and 13 odor components such as β-caryophyllene and limonene were hypothesized as the odor differential markers of Curcumae Radix decoction pieces of diffe-rent sources. The results showed that Heracles Neo ultra-fast gas phase electronic nose can well analyze the odor characteristics and rapidly and accurately discriminate Curcumae Radix decoction pieces of different sources. It can be applied to the quality control(e.g., online detection) in the production of Curcumae Radix decoction pieces. This study provides a new method and idea for the rapid identification and quality control of Curcumae Radix decoction pieces.

ABSTRACT

The present study aimed to investigate the protective effect of S-propargyl-cysteine (SPRC) on atherosclerosis progression in mice. A mouse model of vulnerable atherosclerotic plaque was created in ApoE-/- mice by carotid artery tandem stenosis (TS) combined with a Western diet. Macrophotography, lipid profiles, and inflammatory markers were measured to evaluate the antiatherosclerotic effects of SPRC compared to atorvastatin as a control. Histopathological analysis was performed to assess the plaque stability. To explore the protective mechanism of SPRC, human umbilical vein endothelial cells (HUVECs) were cultured in vitro and challenged with oxidized low-density lipoprotein (ox-LDL). Cell viability was determined with a Cell Counting Kit-8 (CCK-8). Endothelial nitric oxide synthase (eNOS) phosphorylation and mRNA expression were detected by Western blot and RT-qPCR respectively. The results showed that the lesion area quantified by en face photographs of the aortic arch and carotid artery was significantly less, plasma total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C) were reduced, plaque collagen content was increased and matrix metalloproteinase-9 (MMP-9) was decreased in 80 mg/kg per day SPRC-treated mice compared with model mice. These findings support the role of SPRC in plaque stabilization. In vitro studies revealed that 100 μmol/L SPRC increased the cell viability and the phosphorylation level of eNOS after ox-LDL challenge. These results suggest that SPRC delays the progression of atherosclerosis and enhances plaque stability. The protective effect may be at least partially related to the increased phosphorylation of eNOS in endothelial cells.

ABSTRACT

OBJECTIVE@#To explore the clinical and genetic characteristics of a boy with isolated maternal uniparental disomy of chromosome 20 [UPD(20)mat].@*METHODS@#A child who was admitted to the Tongji Hospital Affiliated to Tongji Medical College of Huazhong University of Science and Technology on April 8,2021. was selected as the study subject. Phenotypic and endocrinological findings of the child were retrospectively analyzed. Whole exome sequencing (WES) and methylation-specific multiplex ligation-dependent probe amplification (MS-MLPA) were carried out for detecting the UPD sequences and copy number variations. Both of his parents were verified by Sanger sequencing. Relevant literature was systematically reviewed.@*RESULTS@#The child, a 3-year-and-8-month-old boy born to a 41-year-old mother by Cesarean delivery at 36+2 gestational weeks due to oligohydramia, had a birth weight of 2 300 g and length of 46 cm. He was admitted to the NICU for feeding difficulties which had persisted despite of clinical management. At the age of 3.75, he had a height of 92.5 cm (< 3rd percentile; 25th ~ 50th percentile at 2.5 years) and a weight of 10.8 kg (< 3rd percentile; 50th percentile at 15 months). He had also presented with growth retardation, short stature, attention deficit and hyperactivity disorder (ADHD), mild mental retardation, and speech and language development disorders. He had simian creases in both hands but no additional dysmorphic signs, and his motor development was normal. Serum insulin, thyroid-stimulating hormone, and insulin growth factor binding protein 3 levels were within the normal ranges, though insulin growth factor-1 (IGF-1) was slightly decreased. Since that time he had continuously used atomoxetine hydrochloride capsules to control his ADHD. WES and MS-MLPA revealed the existence of UPD (20)mat.@*CONCLUSION@#The UPD(20)mat syndrome is characterized by feeding difficulties, growth retardation and short stature. The child in our case has been accompanied by ADHD and speech and language development disorders, which required long-term treatment. For women with advanced maternal age and suggestive phenotypes, genetic testing and counseling should be conducted.

ABSTRACT

Objective:To construct the homogenous evaluation index system for public hospital branches under the background of high-quality development, providing reference for improving the homogenization level of public hospital branches.Methods:By analyzing literature, relevant policies and the management practices of the public hospital branches, a preliminary screening index system for homogenization evaluation of public hospital branches was constructed. Two rounds of Delphi method were used to screen homogenization evaluation indicators for public hospital branches and determine the weights of the indicators. Taking the branches of a tertiary hospital as an example, the indicator system was empirically applied.Results:The homogenization evaluation index system for public hospital branches included 4 first level indicators, 8 second level indicators and 21 third level indicators. The weights of the first level indicators of medical homogeneity, management homogeneity, emergency conversion and satisfaction were 51.33%, 23.16%, 9.00% and 16.51%, respectively. Through empirical application, the homogenization coefficient of the public hospital branche was 0.833 5.Conclusions:The homogenization evaluation index system for public hospital branches was in line with the goals of the construction and development of multiple campuses of one hospital for public hospital. Indicators with low homogenization coefficients were the shortcomings of homogenization in hospital branches. This indicator system provided measurement standards and improvement directions for the homogenization of medical and management in hospital branches.

The patients were divided into the totally thoracoscopic group under hypothermic ventricular fibrillation and the conventional median sternotomy group according to the procedure, and the preoperative baseline data and perioperative outcomes were collected and statistically analyzed using SPSS 22.0.Results:A total of 91 patients matched the criteria for study enrollment, 25 in the totally thoracoscopic group and 66 in the median sternotomy group. There was no statistical difference in the preoperative baseline data between the two groups. The totally thoracoscopic group has advantages in mitral valvuloplasty rate(32.0% vs. 7.6%, P=0.008), transfusion rate(72.0% vs. 98.5%, P<0.001), mechanical ventilation time [(19.0±27.8)h vs.(43.3±58.3)h, P=0.009], chest drainage tube time [(2.2±1.9)days vs.(3.7±2.4)days, P=0.004], postoperative chest drainage volume [(489.6±319.1)ml vs.(913.6±568.4)ml, P=0.001], postoperative discharge time[(8.0±2.7)days vs.(13.9±12.8)days, P=0.026]. The totally thoracoscopic group had a longer cardiopulmonary bypass time [(180.8±41.7)min vs.(143.2±39.7)min, P<0.001], and it had an intraoperative ventricular fibrillation time of(100.2±42.5)min. There were no statistically significant differences in the postoperative complication rate(12.0% vs. 21.2%, P=0.481) and mortality(4.0% vs. 4.5%, P=1.000) between the two groups. Conclusion:The totally thoracoscopic approach has the characteristics of less invasion and faster recovery compared with the median sternotomy approach. Hypothermic ventricular fibrillation simplifies the procedure at the ascending aorta while reducing myocardial injury than conventional occlusion of the ascending aorta. Totally thoracoscopic mitral valve surgery under hypothermic ventricular fibrillation is a safe minimally invasive technique.

ABSTRACT

Background@#The present study aimed to digitally evaluate the risk of overwork-related adverse effects (OrAEs) among employees from various occupational categories in Taiwan. @*Methods@#Anonymous data of employees from seven companies/factories providing occupational health services were analyzed. The studied population comprised 5505 employees, and the data analyzed included employment duration, working hours, shift work schedules, and health checkup results. The risk for OrAEs was assessed by an index, Karo index (0-4, the larger the value, the higher the risk for OrAEs) obtained using a risk matrix made up of cardiocerebral and occupational risk factors. Karo index values of 3 and 4 were categorized as at high risk for OrAEs (h-OrAEs). @*Results@#The 5505 employees had an average employment duration of 8.5 years and a mean age of 39.4 years. The prevalence rates for h-OrAEs of the seven companies/factories ranged from 3.9% to 34.2%. There were significant differences in prevalence rates for h-OrAEs between employees of retail stores and high-tech manufacturing factories. Multivariate analysis results indicated that workers of high-tech manufacturing factories had significantly higher risk for h-OrAEs compared with retail store workers. @*Conclusion@#In terms of satisfying health risk management and legal requirements in Taiwan, the newly issued Karo index, which covers a wide range of occupational risk factors, can serve as an assessment and a warning tool for managing the risk of OrAEs in workplaces. To reduce risks for h-OrAEs, active and prudent control of cerebrocardiovascular risks and working hours is recommended.

ABSTRACT

ObjectiveTo observe the effect of ethyl acetate extract of Acanthopanacis Senticosi Radix et Rhizoma seu Caulis on high-fat diet-induced apolipoprotein E gene knockout (ApoE-/-) mice, and explore its mechanism of treating atherosclerosis by regulating intestinal flora. MethodThirty-two 8-week-old male ApoE-/- mice were randomly divided into model group, rosuvastatin group (10 mg·kg-1), high-, low-dose groups of ethyl acetate extract of Acanthopanacis Senticosi Radix et Rhizoma seu Caulis (75, 25 mg·kg-1), with 8 mice in each group. Eight C57BL/6 mice were used as blank group. After 8 weeks of continuous administration, blood was taken to determine the blood lipid level. Enzyme-linked immunosorbent assay (ELISA) was used to detect the contents of related indexes in serum of mice. Hematoxylin-eosin (HE) staining was used to observe the formation of aortic plaque in mice. Cecal contents were collected and 16S rRNA amplicon sequencing was used to detect intestinal flora. ResultCompared with the blank group, the plaque area of the model group was significantly increased with inflammatory infiltration, the contents of triglyceride (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), inflammatory factors and inducible nitric oxide synthase (iNOS) were increased, while the content of high-density lipoprotein cholesterol (HDL-C) was decreased. Compared with the model group, rosuvastatin group and high- and low-dose groups of ethyl acetate extract of Acanthopanacis Senticosi Radix et Rhizoma seu Caulis could improve the deposition of aortic plaque, reduce the contents of TG, TC, LDL-C, inflammatory factors and iNOS, and increase the content of HDL-C. Compared with the blank group, the relative abundances of Firmicutes and Proteobacteria in the model group increased, while the relative abundance of Bacteroidetes decreased. Alpha and Beta diversity analysis showed that samples of each group could be significantly isolated, and the total number and abundance of intestinal flora species in the model group were low. Compared with the model group, ethyl acetate extract of Acanthopanacis Senticosi Radix et Rhizoma seu Caulis could increase the relative abundance of beneficial bacteria and decrease the relative abundance of pathogenic bacteria. ConclusionEthyl acetate extract of Acanthopanacis Senticosi Radix et Rhizoma seu Caulis was mainly composed of flavonoids, which can treat atherosclerosis by regulating the intestinal flora and improve the pathological changes in the aorta of ApoE-/- mice induced by high-fat diet. The mechanism may be related to its ability to reduce the level of inflammatory factors, improve antioxidant capacity and repair the disorder of intestinal flora structure.

ABSTRACT

Derived from Curcuma plants, Curcumae Longae Rhizoma, Curcumae Rhizoma, Wenyujin Rhizoma Concisum, and Curcumae Radix are common blood-activating and stasis-resolving medicinals in clinical practice, which are mainly used to treat amenorrhea, dysmenorrhea, chest impediment and heart pain, and rheumatic arthralgia caused by blood stasis block. According to modern research, the typical components in medicinals derived from Curcuma plants, like curcumin, demethoxycurcumin, bisdemethoxycurcumin, curdione, germacrone, curcumol, and β-elemene, have the activities of hemorheology improvement, anti-platelet aggregation, anti-thrombosis, anti-inflammation, anti-tumor, and anti-fibrosis, thereby activating blood and resolving stasis. However, due to the difference in origin, medicinal part, processing, and other aspects, the efficacy and clinical application are different. The efficacy-related substances behind the difference have not yet been systematically studied. Thus, focusing on the efficacy-related substances, this study reviewed the background, efficacy and clinical application, efficacy-related substances, and "prediction-identification-verification" research method of blood-activating and stasis-resolving medicinals derived from Curcuma plants, which is expected to lay a theoretical basis for the future research on the "similarities and differences" of such medicinals based on integrated evidence chain and to guide the scientific and rational application of them in clinical practice.
