Abstract
Biofilms are widely used and play important roles in biological processes. Low temperature of wastewater inhibits the development of biofilms derived from wastewater activated sludge. However, the specific mechanism of temperature on biofilm development is still unclear. This study explored the mechanism of temperature on biofilm development and found a feasible method to enhance biofilm development at low temperature. The amount of biofilm development decreased by approximately 66 % and 55 % at 4 °C and 15 °C, respectively, as compared to 28 °C. The cyclic dimeric guanosine monophosphate (c-di-GMP) concentration also decreased at low temperature and was positively correlated with extracellular polymeric substance (EPS) content, formation, and adhesion strength. Microbial community results showed that low temperature inhibited the normal survival of most microorganisms, but promoted the growth of some psychrophile bacteria like Sporosarcina, Caldilineaceae, Gemmataceae, Anaerolineaceae and Acidobacteriota. Further analysis of functional genes demonstrated that the abundance of functional genes related to the synthesis of c-di-GMP (K18968, K18967 and K13590) decreased at low temperature. Subsequently, the addition of exogenous spermidine increased the level of intracellular c-di-GMP and alleviated the inhibition effect of low temperature on biofilm development. Therefore, the possible mechanism of low temperature on biofilm development could be the inhibition of the microorganism activity and reduction of the communication level between cells, which is the closely related to the EPS content, formation, and adhesion strength. The enhancement of c-di-GMP level through the exogenous addition of spermidine provides an alternative strategy to enhance biofilm development at low temperatures. The results of this study enhance the understanding of the influence of temperature on biofilm development and provide possible strategies for enhancing biofilm development at low temperatures.

Abstract
Objective: To explore the causes and therapeutic effects of pelvic pain caused by rectal fistula or bladder fistula after comprehensive treatment of cervical cancer and rectal cancer (radiotherapy, surgery, chemotherapy, and other treatments). Methods: A retrospective analysis was conducted on the clinical and pathological data of patients with pelvic tumors admitted to the First People's Hospital of Yinchuan City, Ningxia and the Affiliated Cancer Hospital of Zhengzhou University from June 2016 to June 2022. The causes of persistent pelvic pain in patients after comprehensive treatment was investigated, and the corresponding therapeutic effects after clinical treatment was observed. Results: Thirty-two tumor patients experienced persistent pain after comprehensive treatment, including 22 cases of cervical cancer and 10 cases of rectal cancer. The preoperative pain of the entire group of patients was evaluated using the digital grading method, with a pain score of (7.88±1.31) points. Among the 32 patients, there were 16 cases of rectovaginal fistula or ileovaginal fistula, 9 cases of vesicovaginal fistula, 5 cases of rectoperineal fistula, and 2 cases of vesicovaginorectal fistula. Thirty-two patients were initially treated with medication to relieve pain, and according to the ruptured organs, a fistula was made to the corresponding proximal intestinal canal and renal pelvis to intercept the intestinal contents and urine. However, the pain did not significantly be improved. The pain score of treatment with the above methods for one week was (8.13±1.13) points, and there was no statistically significant difference compared to preoperative treatment (P=0.417). In the later stage, based on a comprehensive evaluation of whether the tumor had recurred, the value of organ preservation, the benefits of surgery, the balance between survival time and improving quality of life, pathological organ resection or repair was performed. The surgical methods included repair of leaks, local debridement combined with irrigation of proximal intestinal fluid, distal closure of the sigmoid colon combined with proximal ostomy, posterior pelvic organ resection, anterior pelvic organ resection, and total pelvic organ resection. One week after surgery, the patients' pain completely relieved or disappeared, with the pain score of (1.72±1.37) points, which was significantly divergent from the preoperative and initial surgical treatments (P<0.001). Conclusions: Palliative pyelostomy and proximal enterostomy cannot effectively alleviate persistent pelvic floor pain. The fundamental way to alleviate pain is complete blocking of the inflammatory erosion of the intestinal fluid and urine.

Abstract
Objective: To investigate serum vitamin A and vitamin D status in children aged 2-<7 years in 20 cities in China. Methods: A cross-sectional study was conducted. A total of 2 924 healthy children aged 2-<7 years were recruited from September 2018 to September 2019 from 20 cities in China, categorized by age groups of 2-<3 years, 3-<5 years, and 5-<7 years. The demographic and economic characteristics and health-related information of the enrolled children were investigated. Body weight and height were measured by professional staff members. The serum vitamin A and vitamin D levels were detected by high-performance liquid chromatography-tandem mass spectrometry. Chi-square test and Logistic regression were applied to analyze the association between vitamin A and vitamin D deficiency and insufficiency as well as their underlying impact factors. Results: The age of the 2 924 enrolled children was 4.33 (3.42, 5.17) years. There were 1 726 males (59.03%) and 1 198 females (40.97%). The prevalences of vitamin A and vitamin D deficiency in enrolled children were 2.19% (64/2 924) and 3.52% (103/2 924), respectively, and the insufficiency rates were 29.27% (856/2 924) and 22.20% (649/2 924), respectively. Children with both vitamin A and vitamin D deficiencies or insufficiencies were found in 10.50% (307/2 924) of cases. Both vitamin A (χ2=7.91 and 8.06, both P=0.005) and vitamin D (χ2=71.35 and 115.10, both P<0.001) insufficiency rates were higher in children aged 3-<5 and 5-<7 years than those in children aged 2-<3 years. Vitamin A and vitamin D supplementation in the last 3 months was a protective factor for vitamin A and D deficiency and insufficiency, respectively (OR=0.68 and 0.22, 95%CI 0.49-0.95 and 0.13-0.40, both P<0.05). The rates of vitamin A and D insufficiency was higher in children with annual household incomes <60 000 RMB than in those with annual household incomes ≥60 000 RMB (χ2=34.11 and 10.43, both P<0.01). Northwest and Southwest had the highest rates of vitamin A and vitamin D insufficiency in children aged 2-<7 yeas, respectively (χ2=93.22 and 202.54, both P<0.001). Conclusions: Among 20 cities in China, children aged 2-<7 years experience high rates of vitamin A and vitamin D insufficiency, which are affected by age, family economic level, vitamin A and vitamin D supplementation, and regional economic level. The current results suggest that high level of attention should be paid to vitamin A and vitamin D nutritional status of preschool children.

Abstract
Objective: To investigate and verify a novel acute graft versus host disease (aGVHD) prevention protocol in the context of haploidentical hematopoietic stem cell transplantation (haplo-HSCT) . Methods: Patients who underwent haplo-HSCT in our center between January 2022 and December 2022 were included. All patients received reduced doses of cyclophosphamide, Rabbit anti-human tymoglobulin, ruxolitinib, methotrexate, cyclosporine, and MMF to prevent aGVHD. The transplantation outcomes, complications, and survival rate of all patients were investigated. Results: A total of 52 patients with haplo-HSCT were enrolled, 29 (55.8%) male and 23 (44.2%) female, with a median age of 28 (5-59) years. There were 25 cases of acute myeloid leukemia, 17 cases of acute lymphocyte leukemia, 6 cases of myelodysplastic syndrome, 2 cases of chronic myeloid leukemia and 2 cases of myeloproliferative neoplasms. 98.1% of patients had successful engraftment. The incidence of Ⅱ-Ⅳ aGVHD and Ⅲ-Ⅳ aGVHD was 19.2% (95% CI 8.2% -30.3% ) and 7.7% (95% CI 0.2% -15.2% ), respectively. No patients experienced severe gastrointestinal mucositis. The Epstein-Barr virus and CMV reactivation rates were 40.4% and 21.3%, respectively. 9.6% of patients relapsed during followup, with 1-year overall survival, progression-free survival, and non-relapse mortality rates of 86.5% (95% CI 76.9% -96.1% ), 78.8% (95% CI 67.4% -90.3% ) and 11.5% (95% CI 2.6% -20.5% ), respectively. Conclusion: Ruxolitinib combined with a low dose of PTCY is a safe and effective first-line aGVHD prevention strategy.

Abstract
Starvation disturbance due to nutrient limitation is a common problem in bioreactors. However, an understanding of how microbial systems respond to starvation remains in its infancy. Here the metabolic response mechanism of a biofilm community to starvation was investigated using a well-controlled gaseous toluene treatment biofilter through interruption of its operation. It was found that metabolic characteristics showed significant differences before and after starvation. The dominant carbon source utilization type shifted from amino acids and carboxylic acids to esters and carbohydrates after starvation, which is more conducive to improving energy production. Metagenomic sequencing analysis supported that the changes in the dominant metabolic substrate, enhanced metabolic stability, and flexibility in the mode of energy metabolism could be the main ways to guarantee functional resilience in ecosystems after starvation. The results highlight the microbial metabolic response to starvation, which would be beneficial to the understanding of functional resilience and bioreactor stability.

Abstract
Objective: To investigate the clinical features, imaging manifestations, histopathological characteristics, and surgical outcomes in pediatric progressive restrictive strabismus. Methods: A retrospective case series study was conducted, including data from 9 cases (9 eyes) of pediatric progressive restrictive strabismus treated at Tianjin Eye Hospital from June 2017 to October 2022. The study compared the degree of globe protrusion in both eyes, changes in eyelid fissure height during internal and external rotation in the primary gaze, summarized clinical characteristics, and analyzed intraoperative conditions, surgical outcomes and postoperative histopathological results of strabismus correction surgery. Statistical analysis was performed using Wilcoxon signed-rank test and Friedman two-way analysis of variance. Results: All 9 cases involved unilateral onset, with 4 males and 5 females. Three cases affected the right eye, and six affected the left eye. Onset age ranged from 2 to 40 months. The degree of globe protrusion in the affected eyes was 13.00 (12.00, 13.00) mm for the right eye and 12.00 (12.00, 13.50) mm for the left eye, with no statistically significant difference (Z=-1.00, P=0.317). There were no significant changes in eyelid fissure height during internal rotation [8.00 (7.25, 8.00) mm], primary gaze [7.50 (7.00, 8.00) mm], and external rotation [8.00 (7.75, 8.00) mm] in the affected eyes (χ²=1.00, P=0.607). No apparent abnormalities were observed in head CT or MRI scans, serum, or immunological tests. However, orbital CT or MRI scans indicated thickening of different extraocular muscle bellies. Six out of nine cases underwent strabismus correction surgery, and postoperative examination revealed restriction in eye movement despite achieving orthophoria in the primary gaze. Tissue pathology of three cases showed increased collagen fiber proliferation in one, scattered bundles of smooth muscle fibers amid diffuse collagen fiber proliferation in another, and abnormal proliferation of striated muscle fibers with varying diameters, increased paired box (PAX)7-positive satellite cells expressing slow muscle myosin in the third case. Conclusions: Pediatric progressive restrictive strabismus presents with restrictive changes, without significant alterations in globe protrusion and eyelid fissure height. Imaging examinations reveal thickening of the extraocular muscle bellies in the affected eye. Although strabismus correction surgery improves eye position, postoperative eye movement remains restricted. Histopathological findings in some cases show abnormal proliferation of skeletal muscle fibers or collagen fibers.

Abstract
Objective: To analyze the clinical pathological and genetic mutation characteristics of conjunctival lymphoepithelial carcinoma. Methods: A retrospective case series study was conducted. Data from three patients diagnosed with conjunctival lymphoepithelial carcinoma and treated with tumor resection surgery at Tianjin Eye Hospital from January 2006 to December 2022 were collected. Four paraffin specimens (including one patient undergoing two surgeries) were subjected to immunohistochemical staining for epithelial antigen and lymphocytic antigen. Epstein-Barr virus (EBV)-encoded RNA (EBER) was detected using in situ hybridization, and whole-exome sequencing was performed on three specimens from two patients using next-generation sequencing methods. Results: All three patients were males aged over 65, with a disease duration ranging from 3 to 44 months. The tumors were unilateral, located on the bulbar or limbal conjunctiva, appearing red, with a maximum diameter of 4-20 mm. Imaging examinations revealed anterior location of the tumors with no involvement of the orbital bone, extraocular muscles, optic nerve, or paranasal sinuses. No local lymph node metastasis was observed in any patient. Pathological findings included undifferentiated carcinoma nests with significant reactive lymphocytic and plasma cell infiltration. Tumor cells were positive for pan-cytokeratin (CK-pan), epithelial membrane antigen (EMA), tumor protein 40 (p40), and tumor protein 63 (p63), with a cell proliferation index (Ki67) exceeding 80%. Cluster of differentiation 20 (CD20), CD3, and CD8 were positive for lymphocytes. In situ hybridization showed partial tumor cell expression of EBER in two specimens of one patient. Whole-exome sequencing revealed 58, 50, and 36 mutated genes in the three specimens, with enriched signaling pathways including melanoma signaling pathway, Notch1 signaling pathway, and RHOQ GTP cycle; enriched biochemical processes included amino acid starvation response, programmed cell death, regulation of lipid synthesis, sodium ion transport, and chromosome segregation. The common mutated gene in all three specimens was SZT2, and SZT2 was involved in the amino acid starvation response. One patient underwent a second complete resection surgery 40 months after partial excision, while the other two underwent complete resection surgery without recurrence. Two patients did not undergo radiation or chemotherapy, and one was lost to follow-up. Conclusions: Conjunctival lymphoepithelial carcinoma is associated with prominent lymphocytic and plasma cell infiltration, some cases are associated with EBV infection, and SZT2 mutations are present in conjunctival lymphoepithelial carcinoma.

Abstract
Objective: To investigate the clinical pathological characteristics of ocular adnexal follicular lymphoma (OAFL). Methods: A retrospective case series study was conducted. Clinical data of 10 OAFL patients diagnosed at Tianjin Eye Hospital from January 1990 to May 2022 were collected. The study analyzed general patient information, medical history, site of involvement, imaging, histopathology, and molecular detection. Among them, 7 cases underwent Epstein-Barr virus-encoded small RNA (EBER) and B-cell lymphoma protein 2 (BCL-2)/immunoglobulin heavy chain gene (IgH) translocation gene detection. Treatment and prognosis of patients were followed up. Results: All 10 patients (10 eyes) had unilateral involvement, including 5 males and 5 females, with an age range of 58 (43, 68) years. Clinical manifestations included eyelid swelling, pink conjunctival thickening, painless slow-growing masses in the lacrimal gland area, extraconal muscle cone, conjunctiva, lacrimal sac, or a combination of lacrimal sac and conjunctiva. Among them, 8 cases were primary, and 2 cases were secondary. According to the Ann Arbor staging, 8 cases were stage Ⅰ-Ⅱ E, and 2 cases were stage Ⅲ E. Histopathological grading revealed 6 cases of grade 1-2 and 3 cases of grade 3A. One case showed grade 3B in the lacrimal sac area and grade 1-2 in the conjunctiva. The predominant subtype was follicular in 4 cases, diffuse in 3 cases, and mixed in 2 cases. One case had a mixed subtype involving the lacrimal sac and conjunctiva. All patients expressed positivity for leukocyte differentiation antigens (CD) 20, CD21, and CD23. Nine cases were positive for CD10, with 1 case showing partial CD10 positivity. All patients were positive for B-cell lymphoma protein 6 (BCL-6), and 9 cases were positive for BCL-2. Specific markers CyclinD1 and Multiple Myeloma Oncogene Protein 1 (MUM-1) were negatively expressed in all cases. The Ki-67 proliferation index ranged from 10% to 90%. Molecular detection was performed in 7 patients, with none showing positive EBER in situ hybridization. However, 5 cases exhibited BCL2/IgH gene fusion. Among 7 patients with follow-up data, the median follow-up time was 17 (6, 34) months. Four patients achieved complete remission, 2 had partial remission, and 1 patient died due to lung infection. Conclusions: OAFL is a tumor originating from follicular center B-cells, characterized by positive expression of BCL-2, CD10, and BCL-6. It can involve the lacrimal gland, extraconal muscles, lacrimal sac, and conjunctiva. Patients generally have a favorable prognosis.

Abstract
Bacterial communication interruption based on quorum quenching (QQ) has been proven its potential in biofilm formation inhibition and biofouling control. However, it would be more satisfying if QQ could be combined with the efficient degradation of contaminants in environmental engineering. In this study, we engineered a biofilm of Pseudomonas putida through introducing a QQ synthetic gene, which achieved both biofilm formation inhibition and efficient degradation of benzene series in wastewater. The aiiO gene introduced into the P. putida by heat shock method was highly expressed to produce QQ enzyme to degrade AHL-based signal molecules. The addition of this engineered P. putida reduced the AHLs concentration, quorum sensing gene expression, and connections of the microbial community network in activated sludge and therefore inhibited the biofilm formation. Meanwhile, the sodium benzoate degradation assay indicated an enhanced benzene series removal ability of the engineering bacteria on activated sludge. Besides, we also demonstrated a controllable environmental risk of this engineered bacteria through monitoring its abundance and horizontal gene transfer test. Overall, the results of this study suggest an alternative strategy to solve multiple environmental problems through genetic engineering means and provide support for the application of engineered bacteria in environmental biotechnology.

Abstract
Objective: To comprehensively assess the current status of extrauterine growth restriction (EUGR) in very preterm infants (VPI) and its associated factors in Chinese neonatal intensive care units (NICU). Methods: In this cohort study, 6 179 preterm infants born at <32 weeks' gestation were included, who were admitted to 57 hospitals in the China Neonatal Network in 2019 and hospitalized for ≥7 days. EUGR was evaluated by a cross-sectional definition (weight at discharge<10th percentile for postmenstrual age), a longitudinal definition (decline in weight Z score>1 from birth to discharge), and weight growth velocity. The comparison between infants with and without EUGR was conducted by t-test, Mann-Whitney U test or χ2 test as appropriate. Multivariable Logistic regression models were used to evaluate associations between EUGR with different definitions and maternal and neonatal factors, clinical practices, and neonatal morbidities. Results: A total of 6 179 VPI were enrolled in the study, with a gestational age of (29.8±1.5) weeks and birth weight of (1 365±304) g; 56.2% (3 474) of them were male. Among them, 48.4% (2 992 VPI) were cross-sectional EUGR and 74.9% (4 628 VPI) were longitudinal EUGR. Z score of weight was (0.13±0.78) at birth and decrease to (-1.35±0.99) at discharge. The weight growth velocity was 10.13 (8.42, 11.66) g/(kg·d). Multivariate Logistic regression analysis showed that among the influential factors that could be intervened after birth, late attainment of full enteral feeds (ORadjust=1.01, 95%CI 1.01-1.02, P<0.001; ORadjust=1.01, 95%CI 1.01-1.02, P<0.001), necrotizing enterocolitis≥Ⅱstage (ORadjust=2.64, 95%CI 1.60-4.35, P<0.001; ORadjust=1.62, 95%CI 1.10-2.40, P<0.001) and patent ductus arteriosus (ORadjust=1.94, 95%CI 1.50-2.51, P<0.001; ORadjust=1.63, 95%CI 1.29-2.06, P<0.001) were all associated with increased risks of both cross-sectional and longitudinal EUGR. In addition, late initiation of enteral feeds (ORadjust=1.06, 95%CI 1.02-1.09, P=0.020) and respiratory distress syndrome (ORadjust=1.45, 95%CI 1.24-1.69, P<0.001) were all associated with cross-sectional EUGR. Breast milk feeding (ORadjust=1.33, 95%CI 1.05-1.68, P<0.001) was associated with a higher risk of longitudinal EUGR. Conclusions: The incidence of EUGR in VPI in China is high. Some modifiable risk factors provide priorities to improve postnatal growth for VPI. Nutritional management of VPI and the efforts to decrease the incidence of complications are still the focus of clinical management in China.

Abstract
Knee osteoarthritis (KOA) is a degenerative joint illness which leads to knee pain and functional limitation. In this study, we combined microfracture surgery with kartogenin (KGN), a small bioactive molecule used to promote the differentiation of mesenchymal stem cells (MSCs), and explored its impact on cartilage repair and possible latent mechanisms of action. The research offers a brand-new idea for the clinical cure of KOA. The microfracture technique in combination with KNG treatment was performed on a rabbit model of KOA. Animal behaviour was evaluated after the intra-articular injection of miR-708-5p and Special AT-rich sequence binding protein 2 (SATB2) lentiviruses. Later, the expression of the tumour necrosis factor α (TNF-α) and interleukin- 1 (IL-1), the pathology of synovial tissue and cartilage tissue, and the positive cartilage type II collagen, MMP-1, MMP-3 and TIMP-1 were detected. Finally, a luciferase assay was conducted to verify the interaction of miR-708-5p and SATB2. Our results showed that miR-708-5p was elevated in the rabbit KOA model; however, the expression of SATB2 was reduced. Meanwhile, the microfracture technology combined with MSCs inducer KGN drove cartilage repair and regeneration in rabbit KOA by repressing the miR-708-5p expression. We also found that miR-708-5p directly targeted the SATB2 mRNA to regulate its expression. Furthermore, our data urged that elevating miR-708-5p or restraining SATB2 may reverse the therapeutic effect of the microfracture technique combined with MSCs inducer on rabbit KOA. Microfracture technique combined with MSCs inducer represses miR-708-5p to target SATB2 to drive cartilage repair and regeneration in rabbit KOA. This indicates that the microfracture technique combined with MSCs inducers is supposed to be an effective latent method for osteoarthritis cure.

Abstract
Trichloroethylene is carcinogenic and poorly degraded by microorganisms in the environment. Advanced Oxidation Technology is considered to be an effective treatment technology for TCE degradation. In this study, a double dielectric barrier discharge (DDBD) reactor was established to decompose TCE. The influence of different condition parameters on DDBD treatment of TCE was investigated to determine the appropriate working conditions. The chemical composition and biotoxicity of TCE degradation products were also investigated. Results showed that when SIE was 300 J L-1, the removal efficiency could reach more than 90%. The energy yield could reach 72.99 g kWh-1 at low SIE and gradually decreased with the increase of SIE. The k of the Non-thermal plasma (NTP) treatment of TCE was about 0.01 L J-1. DDBD degradation products were mainly polychlorinated organic compounds and produced more than 373 mg m-3 ozone. Moreover, a plausible TCE degradation mechanism in the DDBD reactors was proposed. Lastly, the ecological safety and biotoxicity were evaluated, indicating that the generation of chlorinated organic products was the main cause of elevated acute biotoxicity.

Abstract
The existence of quorum sensing (QS) and quorum quenching (QQ) plays important roles in biofilm formation. However, direct detection of QS ability is difficult due to the low concentrations of signal molecules inside the biofilm. Therefore, QQ activity is typically used to indicate the attribution of QS/QQ to the biofilm. Nevertheless, current detection methods of QQ activity based on biosensors present undesirable operability and accuracy. In this study, the 96-well plate assay based on a specific biosensor, Agrobacterium tumefaciens A136, and a colorimetric substance, X-gal was established. The reliable fitting results were obtained by standardizing the composition of the A136 X-gal assay solution and optimizing the operating conditions. This method improved the accuracy of QQ activity detection and reduced time and cost consumption. Finally, the 96-well plate assay was successfully applied to detect the QQ activities of biofilm samples and explore possible environmental influencing factors. In general, this study provided a new strategy for understanding the QQ effect in biofilm systems.

Methods: Visit records of 206 outpatients in the Department of Transplantation, Nanfang Hospital, Southern Medical University were retrospectively collected from October 15, 2022 to October 30, 2022. The distribution of sampling time of tacrolimus blood drug concentration was described and the time range of correction was determined. Twenty inpatients after renal transplantation in the Department of Transplantation, Nanfang Hospital, Southern Medical University from October 1, 2022 to November 30, 2022 were prospectively included, and their demography data, laboratory test results during follow-ups, and CYP3A5 genotype were collected. The patients took tacrolimus in non-sustained-release dosage form every 12 h starting from 19∶30 on the day of admission. Peripheral blood samples were collected from the patients on the second day of admission at 7∶30 and on the third day at 6∶00-10∶00 every 30 minutes to test the blood concentration of tacrolimus. Using the collection time as the independent variable and the blood tacrolimus concentration as the dependent variable, a simple linear regression was performed to fitting a linear model of tacrolimus blood concentration-sampling time. Multiple linear regression was performed to analyze the influencing factors of the tacrolimus metabolic rate within a specific period and generate the regression equation. Results: The 206 outpatients aged (46±13) years, including 131 males (63.6%). The time gap [M (Q1, Q3)] between the sampling time of the follow-up outpatients and standard C12 was 24 (13.0, 46.5) min, and the maximum time gap was 135 min. The 20 enrolled inpatients aged (45±12) years, including 15 males (75.0%). There was no significant difference in the blood concentration of tacrolimus collected at 7∶30 on the second (7.87±2.21)ng/ml and third days (7.84±2.33)ng/ml after admission of the enrolled inpatients (P=0.917), and the blood tacrolimus concentration rhythm was stable in the trial. The plasma concentration of C10.5-C14.5 was linearly related to the time, with R2 [M (Q1, Q3)] 0.88 (0.85, 0.92) and all P<0.05. The metabolic rate of tacrolimus during C10.5-C14.5=0.984+0.090×basic concentration of tacrolimus (ng/ml)-0.036×body mass index+0.489×CYP3A5 genotype-0.007×hemolobin(g/L)-0.035×alanine aminotransferase (U/L)+0.143×total cholesterol (mmol/L)+0.027×total bilirubin (μmol/L), with R2=0.85. Conclusion: This study propose a correction model for tacrolimus (non-sustained-release dosage form) trough concentration around C12, which is helpful for clinicians to easily and accurately assess renal transplant recipients' tacrolimus exposure.

Abstract
Biofilters inoculated with activated sludge are widely used for odor control in WWTP. In this process, biofilm community evolution plays an important role in the function of reactor and is closely related to reactor performance. However, the trade-offs in biofilm community and bioreactor function during the operation are still unclear. Herein, an artificially constructed biofilter for odorous gas treatment was operated for 105 days to study the trade-offs in the biofilm community and function. Biofilm colonization was found to drive community evolution during the start-up phase (phase 1, days 0-25). Although the removal efficiency of the biofilter was unsatisfactory at this phase, the microbial genera related to quorum sensing and extracellular polymeric substance secretion led to the rapid accumulation of the biofilm (2.3 kg biomass/m3 filter bed /day). During the stable operation phase (phase 2, days 26-80), genera related to target-pollutant degradation showed increases in relative abundance, which accompanied a high removal efficiency and a stable accumulation of biofilm (1.1 kg biomass/m3 filter bed/day). At the clogging phase (phase 3, days 81-105), a sharp decline in the biofilm accumulation rate (0.5 kg biomass/m3 filter bed /day) and fluctuating removal efficiency were observed. The quorum quenching-related genera and quenching genes of signal molecules increased, and competition for resources among species drove the evolution of the community in this phase. The results of this study highlight the trade-offs in biofilm community and functions during the operation of bioreactors, which could help improve bioreactor performance from a biofilm community perspective.

Abstract
Objective: To investigate the causes and management of long-term persistent pelvic presacral space infection. Methods: Clinical data of 10 patients with persistent presacral infection admitted to the Cancer Hospital of Zhengzhou University from October 2015 to October 2020 were collected. Different surgical approaches were used to treat the presacral infection according to the patients' initial surgical procedures. Results: Among the 10 patients, there were 2 cases of presacral recurrent infection due to rectal leak after radiotherapy for cervical cancer, 3 cases of presacral recurrent infection due to rectal leak after radiotherapy for rectal cancer Dixons, and 5 cases of presacral recurrent infection of sinus tract after adjuvant radiotherapy for rectal cancer Miles. Of the 5 patients with leaky bowel, 4 had complete resection of the ruptured nonfunctional bowel and complete debridement of the presacral infection using an anterior transverse sacral incision with a large tipped omentum filling the presacral space; 1 had continuous drainage of the anal canal and complete debridement of the presacral infection using an anterior transverse sacral incision. 5 post-Miles patients all had debridement of the presacral infection using an anterior transverse sacral incision combined with an abdominal incision. The nine patients with healed presacral infection recovered from surgery in 26 to 210 days, with a median time of 55 days. Conclusions: Anterior sacral infections in patients with leaky gut are caused by residual bowel secretion of intestinal fluid into the anterior sacral space, and in post-Miles patients by residual anterior sacral foreign bodies. An anterior sacral caudal transverse arc incision combined with an abdominal incision is an effective surgical approach for complete debridement of anterior sacral recalcitrant infections.

Abstract
Objective: To analyze the clinical and pathological characteristics and prognosis of 35 cases of solitary fibrous tumor of ocular adnexal (SFT). Methods: This was a retrospective case series study. The clinical data of 35 cases of ocular adnexal SFT was collected in Tianjin Eye Hospital from January 2000 to December 2020. The clinical manifestations, imaging examination results, pathological characteristics, treatment of patients were analyzed, and patients were followed up. All cases were classified according to the 2013 classification of World Health Organization of tumors of soft tissue and bone. Results: There were 21 males (60.0%) and 14 females (40.0%). The age range was 17 to 83 years, and the median age was 44 (35, 54)years. All patients were unilateral, with 23 (65.7%) in the right eye and 12 (34.3%) in the left eye. The course of disease ranged from 2 months to 11 years, with an a median duration of 12(6,36)months. Clinical manifestations included exophthalmos, limited eye movements, diplopia, and tearing. All patients underwent surgical treatment of complete resection of the tumor. Ocular adnexal SFT mostly occurred in the upper orbit (19 cases, 73.1%). On imaging examination, the tumor showed well-circumscribed space occupying lesion that heterogeneously enhanced with contrast, and abundant blood flow signals in the tumors. MRI showed isointensity or low signal on T1WI, and significantly enhanced on T2WI, presenting intermediate-to-high heterogeneous signals. The tumor diameter was 2.1 (1.5, 2.6) cm. There were 23 cases (65.7%) of classic subtype, 2 cases (5.7%) of giant cell subtype, 8 cases (22.9%) of myxoid subtype, and 2 cases (5.7%) of malignancy. Immunohistochemical staining showed that Vimentin, CD34 and STAT6 were positively expressed in all patients. Twenty-one cases (60.0%) showed positive expression of BCL-2, and Ki-67 positive index ranged from 1.0% to 10.0%. Tumors in this group were all low-risk according to the Demicco risk stratification. Follow-up was available for 25 patients with a duration of 2 years to 14 years and 7 months, and the median follow-up time was 88 (61, 124) months. Two patients relapsed, and no distant metastasis or death was observed. Conclusions: Ocular adnexal SFT mainly presents as a painless, slow-growing mass. And most of them are typical SFT. The imaging manifestations are varied Ocular adnexal SFT generally follows a benign course, with a good prognosis after complete excision. Recurrence could occur many years after surgery which requiring careful and long-term follow-up.

Abstract
Objective: To analyze the expression of C-X-C chemokine receptor 5 (CXCR5)+CD8+ T cells and plasma C-X-C motif chemokine 13 (CXCL13) in severe aplastic anemia (SAA) patients and their correlations with hematological parameters. Methods: The clinical data of 35 SAA patients in the Hematology Department of Tianjin Medical University General Hospital from January 2018 to September 2021 were retrospectively analyzed. The patients were divided into two groups according to whether they had received the medication: untreated SAA group and recovery SAA group. In untreated group, there were 18 patients who had not received any medication, with 9 males and 9 females, and aged 51 (18-76) years. In recovery SAA group, there were 17 patients who were separated from component blood transfusion after the immunosuppressive treatment with anti-thymocyte globulin (ATG) combined with cyclosporine A (CsA), with 7 males and 10 females, and aged 46 (16-70) years. Meanwhile, 20 healthy controls were also selected, including 8 males and 12 females, and aged 45(15-72) years. Peripheral blood and bone marrow samples were collected from SAA patients, while peripheral blood samples were obtained from healthy controls. Flow cytometry was used to detect the percentage of CXCR5+CD8+ T cells in peripheral blood and bone marrow samples. The concentration of plasma CXCL13 was measured by enzyme-linked immunosorbent assay (ELISA). The correlations between the percentage of CXCR5+CD8+ T cells and the concentration of CXCL13, as well as the correlations between these two parameters and the hematological parameters were analyzed by Spearman correlation analysis. Results: The proportion of CXCR5+CD8+ T cells in the bone marrow of untreated SAA group was (4.9±2.9)%, which was higher than that of recovery SAA group (2.7±1.5)%, with a statistically significant difference (t=2.34, P=0.027). The proportion of CXCR5+CD8+ T cells in peripheral blood of untreated SAA group, recovery SAA group and healthy control group was (8.4±4.2)%, (3.8±2.3)% and (2.6±2.0)% respectively. The proportion of CXCR5+CD8+ T cells in peripheral blood of untreated SAA group was higher than that of recovery SAA group and healthy control group (both P<0.05). The plasma CXCL13 concentration in untreated SAA group was (97.2±46.8) ng/L, which was significantly higher than that in recovery SAA group [(54.9±20.9) ng/L] and healthy control group [(47.6±17.3) ng/L] (both P<0.05). The proportion of CXCR5+CD8+ T cells in peripheral blood of SAA patients was positively correlated with the concentration of plasma CXCL13 (r=0.545, P<0.001). The proportion of peripheral blood CXCR5+CD8+ T cells in SAA patients was negatively correlated with white blood cell count, platelets count, percentage of neutrophils, absolute neutrophils count, percentage of reticulocytes, absolute reticulocytes count, bone marrow myeloid cells, bone marrow erythroid cells and megakaryocytes count (r=-0.556, -0.392, -0.617, -0.615, -0.395, -0.543, -0.432, -0.484 and -0.523, all P<0.05). The proportion of peripheral blood CXCR5+CD8+ T cells was positively correlated with the percentage of peripheral blood lymphocytes and bone marrow lymphoid cells (r=0.593 and 0.556, both P<0.05). Meanwhile, the concentration of plasma CXCL13 in SAA patients was negatively correlated with white blood cell count, absolute neutrophils count, percentage of reticulocytes, absolute reticulocytes count and bone marrow myeloid cells (r=-0.447, -0.446, -0.498, -0.407 and -0.456, all P<0.05), but positively correlated with bone marrow lymphoid cells (r=0.384, P<0.05). Conclusions: The proportion of CXCR5+CD8+ T cells and the concentration of plasma CXCL13 increases in SAA patients. The proportion of CXCR5+CD8+ T cells in peripheral blood is positively correlated with the concentration of CXCL13. Moreover, the proportion of CXCR5+CD8+ T cells and the concentration of CXCL13 are correlated with many hematological parameters, which may play a critical role in the immune pathogenesis of SAA.

Abstract
Objective: To investigate the clinicopathological features of pulmonary granular cell tumors (pGCTs) and to improve the diagnostic accuracy of the tumor. Methods: A total of 5 pGCTs were diagnosed from February 2016 to January 2022 at Shanghai Pulmonary Hospital, Tongji University School of Medicine and Fudan University Shanghai Cancer Center, China. Immunohistochemical staining, and analysis of the clinicopathological characteristics were performed. Results: The average age of the pGCTs patients was 46 years (ranging from 24 to 54 years), with 3 females and 2 males. One case occurred in the bronchus with multiple nodules in the lung, 2 cases occurred in the bronchial opening, and 2 cases were solitary nodules in the lung. The maximum diameter of the tumors ranged from 12 to 15 mm (mean size 14 mm). Microscopically, the tumor showed infiltrative growth and consisted of round, oval or polygonal cells. Abundant eosinophilic cytoplasm was noted, and the nucleoli were prominent. None of the 5 cases showed any mitosis or necrosis. Immunohistochemical and histochemical study showed positive staining for S-100 (5/5), SOX10 (5/5), Vimentin (5/5), TFE3 (4/5), PAS (3/5), and amylase-digested-PAS (3/5), while 4 cases were negative for CD68. TFE3 FISH analyses on 2 cases showed that no signal abnormality was detected in these 2 cases. The average proliferation index of Ki-67 was 2.2% (range 0-5%). There was no recurrence in 4 cases of pGCTs with a follow-up time ranging from 2 months to 60 months. Conclusions: pGCTs are very rare tumors, most likely originating from Schwann cells. Immunohistochemical staining is the conventional diagnostic tool for pGCTs diagnosis. Recognition of this entity is essential for pathologists to avoid misdiagnosis and unnecessary treatments.

Abstract
Objective: To investigate the effects of different types of heart failure on long-term renal prognosis in patients with renal insufficiency and heart failure. Methods: The patients with renal insufficiency [baseline estimated glomerular filtration rate < 60 ml·min-1·(1.73 m2)-1] and heart failure followed-up for more than 2 years and hospitalized in Beijing Anzhen Hospital, Capital Medical University from January 1, 2018 to June 30, 2019 were enrolled in this retrospective cohort study. The patients were divided into three groups based on the baseline left ventricular ejection fraction (LVEF): heart failure with reduced ejection fraction (HFrEF, LVEF < 40%) group, heart failure with mildly reduced ejection fraction (HFmrEF, 40% ≤ LVEF < 50%) group, and heart failure with preserved ejection fraction (HFpEF, LVEF ≥ 50%) group. Clinical data were collected and endpoint events (adverse renal outcome: the composite outcome of all-cause death or worsening renal function) were recorded through the electronic medical record system. Kaplan-Meier survival curve was used to analyze the incidence of endpoint events of different heart failure subgroups. Cox regression model was performed to analyze the risk factors of endpoint events. Results: A total of 228 patients with renal insufficiency complicated with heart failure were included, with age of (68.14±14.21) years old and 138 males (60.5%). There were 85 patients (37.3%) in the HFrEF group, 40 patients (17.5%) in the HFmrEF group, and 103 patients (45.2%) in the HFpEF group. There were statistically significant differences in age, proportion of age > 65 years old, sex distribution, systolic blood pressure, pulmonary artery pressure, serum sodium, serum calcium, hemoglobin, serum cholesterol, low-density lipoprotein cholesterol, serum uric acid, troponin I, hypersensitive C-reactive protein, LVEF, ventricular septal thickness, left ventricular end-diastolic diameter, B-type natriuretic peptide, estimated glomerular filtration rate, and proportions of using beta blockers, using spirolactone, myocardial infarction, hypertension, cardiomyopathy and atrial fibrillation (all P < 0.05). During the median follow-up of 36.0 (28.0, 46.0) months, 73 patients (32.0%) had adverse renal outcomes. The total incidences of adverse renal outcomes were 32.9% (28/85) in the HFrEF group, 35.0% (14/40) in the HFmrEF group, and 30.1% (31/103) in the HFpEF group. Kaplan-Meier survival curve showed that there was no significant difference in the incidence of endpoint events among the three groups (log-rank test χ2=0.17, P=0.680). Multivariate Cox regression analysis showed that HFpEF (HFrEF as reference, HR=2.430, 95% CI 1.055-5.596, P=0.037) was an independent influencing factor of endpoint events. Conclusions: The long-term renal prognosis of patients with renal insufficiency and heart failure is poor. Compared with HFrEF, HFpEF is an independent risk factor of poor long-term renal prognosis in renal insufficiency patients with heart failure.

Abstract
A myopic patient with self-reported photorefractive keratectomy 9 years ago requested small incision lenticule extraction (SMILE) as retreatment. The presence of interface bubbles while creating a corneal cap of the right eye revealed that the previous refractive surgery was laser in situ keratomileusis (LASIK). Therefore, the SMILE procedure was resumed in the right eye, but flap-lift LASIK was performed in the left eye. Postoperative follow-up showed that the vision in both eyes reached the preoperative best corrected level. SMILE may be a potential option for refractive regression after LASIK.

Abstract
BACKGROUND Controlling excess biomass accumulation and clogging is important for maintaining the performance of gas biofilters and reducing energy consumption. Interruption of bacterial communication (quorum quenching) can modulate gene expression and alter biofilm properties. However, whether the problem of excess biomass accumulation in gas biofilters can be addressed by interrupting bacterial communication remains unknown. RESULTS In this study, parallel laboratory-scale gas biofilters were operated with Rhodococcus sp. BH4 (QQBF) and without Rhodococcus sp. BH4 (BF) to explore the effects of quorum quenching (QQ) bacteria on biomass accumulation and clogging. QQBF showed lower biomass accumulation (109 kg/m3) and superior operational stability (85-96%) than BF (170 kg/m3; 63-92%) at the end of the operation. Compared to BF, the QQBF biofilm had lower adhesion strength and decreased extracellular polymeric substance production, leading to easier detachment of biomass from filler surface into the leachate. Meanwhile, the relative abundance of quorum sensing (QS)-related species was found to decrease from 67 (BF) to 56% (QQBF). The QS function genes were also found a lower relative abundance in QQBF, compared with BF. Moreover, although both biofilters presented aromatic compounds removal performance, the keystone species in QQBF played an important role in maintaining biofilm stability, while the keystone species in BF exhibited great potential for biofilm formation. Finally, the possible influencing mechanism of Rhodococcus sp. BH4 on biofilm adhesion was demonstrated. Overall, the results of this study achieved excess biomass control while maintaining stable biofiltration performance (without interrupting operation) and greatly promoted the use of QQ technology in bioreactors.

Abstract
Objective: To investigate the clinicopathological features of adult orbital xanthogranulomatous disease (AOXGD) with lacrimal gland reactive lymphoid hyperplasia. Methods: Retrospective case series study. The clinical and pathological data of AOXGD cases diagnosed and treated in Tianjin Eye Hospital from January 2002 to December 2021 was reviewed, and the clinical characteristics, radiologic findings and pathological characteristics of periocular and lacrimal gland lesions of 5 cases were retrospectively analyzed. The expression of IgG4 and IgG protein in periocular and lacrimal gland lesions was detected by immunohistochemical staining, and the role of IgG4 in AOXGD was preliminarily studied. Results: There were four females and one male with an average age of 53.8 years (39 to 77 years). Among the five AOXGD cases, there were three cases of adult-onset xanthogranuloma, one case of adult-onset asthma and periocular xanthogranuloma, and one case of necrobiotic xanthogranuloma. All cases involved both eyes. The swelling of eyelids was observed in five cases, and the yellow or pale yellow eyelid skin was found in two cases. Imaging examinations showed the tumor mainly involved the eyelids, subcutaneous tissues, anterior orbit and lacrimal gland. A large number of foam cells and typical Touton giant cells were found in the periorbital lesions, accompanied by different degrees of fibrosis. The fibrinoid necrosis was detected in one case of necrobiotic xanthogranuloma. The lacrimal gland lesions showed different types of reactive lymphoid hyperplasia, including IgG4-related disease in two cases, follicular lymphoid hyperplasia in two cases and focal lymphoid hyperplasia in one case. IgG4 levels of periorbital and lacrimal gland lesions were elevated in four cases. Asthma and elevated serum IgG4 were found in one case of adult-onset periocular xanthogranuloma. Three patients underwent surgical resection and adjuvant hormone or immunosuppressive therapy, and two patients underwent simple surgical resection. The patients were followed up for 1.5 to 10.0 years, one patient was lost, and four patients had no recurrence. Conclusions: AOXGD with lacrimal gland reactive lymphoid hyperplasia is a group of rare diseases. The periorbital lesions of that are characterized by proliferation of foamy histiocytes and Touton giant cells, and the lacrimal gland lesions of that manifest as IgG4-related disease in some cases.

Abstract
Objective: To investigate the relationship between plasma heat shock proteins 90α(Hsp90α) levels and the white matter hyperintensity(WMH) in patients with cerebral small vessel disease(SVD). Methods: Patients admitted to the Department of Neurology, the First Affiliated Hospital of Zhengzhou University from March to August 2021 and diagnosed with WMH by magnetic resonance examination (MRI) were selected as the case group, matched with physical examination patients who visited the Department of Medical Examination during the same period and showed no WMH on MRI and no history of neurological diseases as the control group, and the level of plasma Hsp90α was quantitatively detected by enzyme-linked immunosorbent assay. Mann-Whitney U test was used to compare whether there was a difference in plasma Hsp90α levels between the control group and the case group.Multivariate logistic regression analysis was used to explore the related factors of WMH in patients with SVD. Results: Of the 183 subjects, the control group (n=73) consisted of 28 males and 45 females, aged (54±10) years, while the case group (n=110) consisted of 71 males and 39 females, aged (64±10) years old. Plasma Hsp90α level was higher in the case group than that of the control group [53.33(35.33, 70.09) ng/ml vs 35.02(18.51, 54.95) ng/ml, P<0.001]. After adjusting for confounding factors by multivariate analysis, the results showed that plasma Hsp90α levels greater than 58.34 ng/ml was associated with WMH (P=0.002, OR=5.931, 95%CI:1.955-17.995). Conclusion: Higher level of plasma Hsp90α is associated with WMH in patients with SVD.

Abstract
Objective: To investigate the clinical characteristics, treatment and prognosis of malignant rhabdoid tumor (MRT) in children. Methods: Clinical data total of 18 children with MRT treated in the Department of Hematology and Oncology, Children's Hospital, the First Affiliated Hospital of Zhengzhou University between June 2015 to June 2021 were analyzed retrospectively. The patients were grouped according to age, gender, tumor type, clinical stage and other factors.Progression free survival (PFS) and overall survival (OS) were calculated by Kaplan-Meier method, survival differences among different groups were compared by Log-rank test, and prognostic factors were analyzed by Cox regression model. Results: Among the 18 patients, there were 5 males and 13 females. The age of disease onset was 30.5 (12.0, 75.0) months, the tumor diameter was (80±29) mm, and no integrase interactor 1 (INI-1) expression was detected by immunohistochemistry. There were 7 cases of malignant rhabdoid tumor of the kidney (MRTK), 6 cases of atypical teratoid rhabdoid tumor (ATRT) and 5 cases of extrarenal extracranial rhabdoid tumor (EERT). At the time of early diagnosis, 12 patients were clinically stage Ⅲ-Ⅳ, 11 patients had local or distant metastasis, and 4 patients had metastasis during treatment. Surgical excision is the preferred treatment. There were 3 cases with preoperative puncture biopsy, 13 cases with complete resection, 4 cases with partial resection, and 1 case without operation. Thirteen patients were treated with the domestic conventional chemotherapy regimen for Wilms' tumor, medulloblastoma and rhabdomyosarcoma, and 5 patients were treated with the international conventional chemotherapy regimen. Nine patients received radiotherapy, including 1 case of MRTK, 4 cases of ATRT and 4 cases of EERT. By the end of follow-up in January 2022, 7 patients survived and 11 patients died. The 3-year PFS and OS rates were (8±8) % and (14±12) %. Log-rank test showed that the 5-year OS of EERT group was higher than ATRT and MRTK groups (χ²=16.31, P<0.001), the tumor diameter <80 mm group was higher than that of the ≥80 mm group (χ²=4.49, P=0.034), and the radiotherapy group was higher than no radiotherapy group (χ²=3.97, P=0.046). The differences were statistically significant. There was no significant difference in the influence of tumor type, age, tumor diameter, radiotherapy and chemotherapy on OS by Cox regression model (all P>0.05). Log-rank test showed that the 3-year PFS of EERT group was higher than ATRT and MRTK groups (χ²=11.14, P=0.004),>3 years group was higher than ≤3 years group (χ²=10.10, P=0.001), the differences were statistically significant. Tumor type, clinical stage, tumor diameter, age, tumor rupture and radiotherapy were included in the Cox regression model, and the results showed that clinical stage (HR=0.49, 95%CI 0.26-0.94, P=0.031), tumor diameter (HR=8.67, 95%CI 1.84-40.89, P=0.006), age (HR=0.01, 95%CI 0.00-0.15, P=0.001) had statistical significance on PFS. Conclusions: MRT is one of the most aggressive and fatal cancers in early childhood and infancy. There is no standard treatment and the prognosis is extremely poor. Clinical stage, tumor size and age are risk factors for disease progression.

Abstract
Proprotein convertase subtilisin/kexin 9 (PCSK9) inhibitors significantly reduce low-density lipoprotein cholesterol (LDL-C) and improve the prognosis of patients with acute coronary syndrome (ACS). However, the feasibility and safety of early application of PCSK9 inhibitors on the basis of statins combined with ezetimibe to strengthen lipid lowering in extremely high-risk coronary heart disease populations are still unknown.This study was a prospective, randomized controlled study. A total of 136 patients with extremely high-risk ACS with LDL-C ≥ 3.0 mmol/L after percutaneous coronary intervention (PCI) treatment were randomly assigned 1:1 to the control group (atorvastatin 40 mg/day and ezetimibe 10 mg/day) or the evolocumab group (evolocumab 140 mg every 2 weeks combined with atorvastatin 40 mg/day and ezetimibe 10 mg/day). We compared the blood lipid profiles, major adverse cardiovascular events (MACEs), and adverse reactions. MACEs included cardiogenic death, nonfatal myocardial infarction, nonfatal stroke, and readmission due to angina. Adverse reactions included allergies, myalgia, poor blood glucose control, and liver damage.Within 1 month, the average level of LDL-C in the evolocumab group decreased from 3.54 to 0.57 mmol/L and that in the control group decreased from 3.52 to 1.26 mmol/L. The LDL-C compliance (< 1.0 mmol/L) rate was significantly increased in the evolocumab group compared with the control group (82.35% versus 22.06%, P < 0.01). The average level of lipoprotein (a) (Lp (a) ) in the control group increased by 9.94 ± 51.93% from baseline after treatment, but evolocumab reduced the Lp (a) level (-38.84 ± 32.40%). Additionally, evolocumab further reduced the levels of apolipoprotein B/A1 (-70.56 ± 22.38% versus -51.29 ± 18.14%), cholesterol (-54.76 ± 18.10% versus -41.16 ± 18.14%), and apolipoprotein B (-66.47 ± 26.89% versus -46.78 ± 24.12%) compared with those in the control group, all P < 0.01. The blood lipid levels of both control and evolocumab groups stabilized after 1 month. During the 3-month follow-up, the incidence of MACEs after PCI was lower in the evolocumab group than in the control group (8.82% versus 24.59%, P = 0.015), and evolocumab combined with statins and ezetimibe did not increase the occurrence of adverse reactions (13.24% versus 11.48%, P = 0.762).In patients with extremely high-risk ACS with high levels of LDL-C, adding evolocumab to their treatment regimen as early as possible may enhance lipid lowering, increase the patient's LDL-C compliance rate in the short term, and improve cardiovascular prognosis but will not increase adverse reactions.

Type of funding sources: Foundation. Main funding source(s): Helse Vest, Norway (LBS), and the Research Council of Norway (SYC).
Background
Cryoballoon ablation is an important method for pulmonary vein (PV) isolation in treatment of atrial fibrillation (AF). Previous studies have shown that thawing time, but not freezing time or temperature, impacts PV reconnection during long-term follow-up. However, it is unknown whether the entire or only part of the thawing stage plays a critical role.
Purposes
This study aimed to clarify the relationship between the durability of PV isolation and the time of phase transition from ice to water indicated by thawing plateau (TP) time during a cryoballoon ablation.
Methods
In this retrospective study, 241 PVs from 71 patients who underwent a repeat AF ablation 526 (IQR: 412, 675) days after a cryoballoon ablation were analyzed. The predictive value of procedural parameters for the durability of PV isolation were evaluated. Definitions of different phases of the temperature-time curve are shown in Figure 1. TP Time is defined as the time from 0 to 10°C inside the balloon in the thawing period (the plateau on the curve).

Reconnection was observed in 101 (41.9%) PVs of 53 patients (74.6%). Durable PV isolation was associated with significantly longer TP Time compared with PV reconnection (26.0 vs. 11.0 s, P<0.001). The proportion of durable PV isolations increased with TP Time in a dose-proportional manner (Figure 2). The cut point for PV reconnection was TP Time <15 s with a positive predictive value of 82.1% (sensitivity=63.4%, specificity=90.0%) while for durable PV isolation the cut point was TP Time >25 s with a positive predictive value of 84.6% (sensitivity=55.0%, specificity=86.1%). After the analysis of multivariable logistic regression, location of PV (P<0.01), and TP Time (P<0.05) were shown as independent predictors for durable PV isolation. None of nadir temperature, initial cooling time, effective freezing time, initial thawing time, or late warming time was independent predictor. Accumulated TP Time for all PVs showed a positive linear correlation with the plasma level of troponin T (ρ=0.624, P<0.01).
Conclusions
TP Time is an independent predictor for the durability of PV isolation, and it presents in a dose-proportional manner. TP Time <15 s predicts long-term reconnection while TP Time >25 s predicts durable PV isolation.

Abstract
Objective: To explore the mechanism of reactive oxygen species/thioredoxin-interacting protein/nucleotide-binding oligomerization domain-like receptor 3 (ROS/TXNIP/NLRP3) pathway in the skin injury of trichloroethylene (TCE) sensitized mice. Methods: In August 2020, 40 female BALB/c mice were randomly divided into control group (n=5) , solvent control group (n=5) , TCE treatment group (n=15) and TCE+(2-(2, 2, 6, 6-Tetrameyhylpiperidin-1-oxyl-4-ylamino)-2-oxoethyl) triphenylphosphonium chloride (Mito TEMPO) treatment group (n=15) . The TCE sensitization model was established. Mice in the TCE treatment group and TCE+Mito TEMPO treatment group were divided into the sensitized positive group and the sensitized negative group according to the skin erythema and edema reactions on the back of the mice 24 h after the last stimulation. The mice were sacrificed 72 h after the last stimulation, the back skin of the mice was taken, and the skin lesions were observed. Immunohistochemistry (IHC) was used to detect the expression level of NLRP3, and the Western Blot was performed to detect the expression levels of NLRP3, apoptosis-associated speck-like protein containing a CARD (ASC) , cysteinyl aspartate specific proteinase 1 (Caspase 1) , Interleukin-1β (IL-1β) and TXNIP proteins in the skin of the mice, the reactive oxygen species (ROS) kit was used to detect the level of intracellular ROS in the back skin tissue. Results: The sensitization rates of TCE treatment group and TCE+Mito TEMPO treatment group were 40.0% (6/15) and 33.3% (5/15) , respectively, and there was no significant difference between the two groups (P>0.05) . The back skin of the mice in the TCE sensitized positive group was thickened and infiltrated by a large number of inflammatory cells. The number of mitochondria in the epidermis cells was significantly reduced, the mitochondrial crest disappeared and vacuolar degeneration occurred. TCE+Mito TEMPO sensitized positive group had less damage, more mitochondria and relatively normal cell structure. Compared with the solvent control group and corresponding sensitized negative groups, the expression levels of NLRP3, ASC, Caspase 1, IL-1β, TXNIP proteins and the content of ROS in the TCE sensitized positive group and TCE+Mito TEMPO sensitized positive group were significantly increased (P<0.05) . Compared with TCE sensitized positive group, the expression levels of NLRP3, ASC, Caspase 1, IL-1β, TXNIP proteins and the content of ROS in the TCE+Mito TEMPO sensitized positive group were significantly decreased (P<0.05) . Conclusion: ROS/TXNIP/NLRP3 pathway was activated and then encouraged the release of IL-1β, finally aggravated the TCE-induced skin injury.

Abstract
Background The current surveillance system only focuses on notifiable infectious diseases in China. The arrival of the big-data era provides us a chance to elaborate on the full spectrum of infectious diseases. Methods In this population-based observational study, we used multiple health-related data extracted from the Shandong Multi-Center Healthcare Big Data Platform from January 2013 to June 2017 to estimate the incidence density and describe the epidemiological characteristics and dynamics of various infectious diseases in a population of 3,987,573 individuals in Shandong province, China. Results In total, 106,289 cases of 130 infectious diseases were diagnosed among the population, with an incidence density (ID) of 694.86 per 100,000 person-years. Besides 73,801 cases of 35 notifiable infectious diseases, 32,488 cases of 95 non-notifiable infectious diseases were identified. The overall ID continuously increased from 364.81 per 100,000 person-years in 2013 to 1071.80 per 100,000 person-years in 2017 (χ2 test for trend, P < 0.0001). Urban areas had a significantly higher ID than rural areas, with a relative risk of 1.25 (95% CI 1.23–1.27). Adolescents aged 10–19 years had the highest ID of varicella, women aged 20–39 years had significantly higher IDs of syphilis and trichomoniasis, and people aged ≥ 60 years had significantly higher IDs of zoster and viral conjunctivitis (all P < 0.05). Conclusions Infectious diseases remain a substantial public health problem, and non-notifiable diseases should not be neglected. Multi-source-based big data are beneficial to better understand the profile and dynamics of infectious diseases.

Abstract
Objective: To describe the use of non-erythrocyte blood products transfusion in very preterm and extremely preterm infants in the neonatal intensive care units (NICU) of the Chinese Neonatal Network (CHNN) in 2019, to explore the disparity between different centers, and to further investigate the rationality and standardability of non-erythrocyte blood products transfusion. Methods: This was a cross-sectional study based on the CHNN cohort of very preterm and extremely preterm infants. All 6 598 infants with gestational age (GA)<32 weeks and admitted to the 57 NICU of CHNN within 24 h of life in 2019 were enrolled. Non-erythrocyte blood products included platelet, plasma, albumin, immunoglobulin, cryoprecipitate and prothrombin complex. Infants who received at least one type of non-erythrocyte blood products were defined in transfusion group. The comparison between infants with and without transfusion was done by t-test, rank-sum test or χ2 test as appropriate. Linear regression model was used to generate adjusted transfusion rate of each center, and to investigate the correlation between adjusted rate and center-level characteristics. Results: A total of 6 598 infants were enrolled in the study, with gestational age of 30.0 (28.7, 31.0) weeks and birth weight of (1 353±312) g, and 43.6 % (2 877) of them were female. Among them, 42.7% (2 816) infants were enrolled in transfusion group, with the times of transfusion as 3 (1, 6) times. Compared to the infants without any transfusion of non-erythrocyte blood products, those infants received transfusion had lower gestational age (Z=17.62, P<0.01), lower birth weight (t=18.64, P<0.01), higher proportion of small-for-gestation age (χ2=31.06, P<0.01), multiple birth (χ²=12.82, P<0.01) and intensive resuscitation in delivery room (χ²=287.52, P<0.01), as well as lower proportion of females (χ²=10.68, P<0.01) and even lower proportion of infants born in this hospital (χ²=78.23, P<0.01). Among the entire study population, albumin (25.4%, 1 674 cases), immunoglobulin (21.5%, 1 417 cases) and plasma (18.9%, 1 245 cases) were the most commonly used non-erythrocyte blood products. Overall, 60.4% (544/901) infants with gestational age <28 weeks received transfusion 4 (2, 8) times. A total of 39.9% (2 272/5 697) infants between 28-31weeks received non-erythrocyte blood products 3 (1, 6) times. The non-erythrocyte blood products transfusion rates of critically-ill and non-critically-ill infants were 62.2% (1 693/2 723) and 29.0% (1 123/3 875) respectively, and the transfusion times were 4 (2,7) and 2 (1,4) times. The transfusion rates varied significantly among different NICU, and the disparities remained obvious after adjustment (adjusted χ²=153.48, P<0.01). Conclusion: Near half of very preterm and extremely preterm infants admitted to Chinese NICU in 2019 receive non-erythrocyte blood products during hospitalization with significant disparities among different hospitals.

Abstract
Objective: To observe the efficacy and safety of albumin-bound paclitaxel in the treatment of metastatic breast cancer. Methods: Multi-center data of patients who accepted single-drug albumin-bound paclitaxel or combination regimens from 2013 to 2019 were collected and the efficacy and safety were evaluated. Kaplan-Meier method was used for survival analysis, while Log-rank test was used to compare the survival rates. Results: A total of 203 advanced breast cancer cases were enrolled. The median progression-free survival time (PFS) lasted for 4 months, the median overall survival(OS)was 14 months, objective response rate (ORR) was 36.0% while the disease control rate (DCR) was 81.3%. The ORRs of Luminal, human epidermal growth factor receptor 2 (HER2) overexpression and triple-negative breast cancer patients underwent albumin-bound paclitaxel treatment were 37.3%, 45.5% and 31.0%, respectively, the DCRs were 85.5%, 68.2% and 78.9%, respectively. The OS of patients with relapse or metastasis who accepted less than two and more than two chemotherapy regimens were 22 months and 11 months (P<0.000 1), the ORRs were 44.9% vs 30.4%, DCRs were 87.2% vs 77.6% (P=0.018). The ORR and DCR of patients who accepted traditional paclitaxel treatment before the albumin-bound paclitaxel treatment were 35.8% and 82.1%, respectively. The common adverse reaction of these patients was numbness of limbs, which incidence rate was 64.5% (131/203), and 61.1% (124/203) were degree 1 to 2. Other adverse reactions including decreased white blood cells, which incidence rate was 56.1% (114/203); nausea and vomit, which incidence rate was 36.9% (75/203); anemia, which incidence rate was 21.2% (43/203); decreased platelet, which incidence rate was 18.7% (38/203); hepatic dysfunction, which incidence rate was 18.2% (37/203). Conclusions: Albumin-bound paclitaxel single or combination regimen is still significant efficient for various molecular subtypes of breast cancer patients or patients with traditional paclitaxel resistance or multi-line chemotherapy failure. Early usage has better prognosis, controllable adverse reaction and prominent clinical application value.

Abstract
Disordered carbons can be considered under the modeling framework of disordered graphene networks (DGNs) due to the continuous three-dimensional connectivity and high graphitization. Correlating microstructures and mechanical behaviors of DGNs to their topology is pivotal to revealing more intrinsic features hidden by disorder. Herein, starting from basic deformations and topology, we investigate DGNs with various densities to explore their micromechanical landscape. Both the tension and shear of DGNs exhibit prolonged plastic platforms through local tearing of microstructures. However, compression displays special plastic damages of forming kinklike puckers and sp3-bonded carbon, resulting in a tension-compression asymmetry of DGNs. Out-of-plane topological defects contribute to the main negative-curvature topology in deformed DGNs. Moreover, there are novel scaling laws where both the Young's modulus and strength (logarithms) follow an inversely proportional scaling with respect to average angular defects. Ashby charts demonstrate that the mechanical properties of DGNs can reach the theoretical limit region, surpassing those of most conventional materials.

Abstract
In this paper, MPDA@hydroxyapatite nanocomposites (MPHA NCs) were prepared and applied to develop a novel reactive oxygen species (ROS)-triggered nitric oxide (NO)-enhanced photothermal therapy nanocomposite system composed of indocyanine green (ICG)/L-arginine-MPDA@HAp (AI-MPHA NCs) for displaying both NO gas therapy and photothermal osteosarcoma treatment. The nanosystem exhibited a mesoporous and core-shell structure and high ICG loading efficiency (about 90%). Under near infrared (NIR) irradiation, the AI-MPHA NCs could not only produce heat but also generate reactive oxygen species (ROS), inducing the catalysis of L-Arg to obtain NO. Under NIR irradiation, the AI-MPHA NCs achieved osteosarcoma ablation by a synergistic combination of photothermal therapy and NO-gas therapy. Additionally, the cell viability of MG-63 cells decreased to 23.6% (co-incubated with AI-MPHA NCs) under irradiation with a power density at 1.0 W cm-2 for 10 min. The study proposed a novel nano-platform for NO-enhanced photothermal therapy of osteosarcoma.

Abstract
Sepsis remains a leading cause of death in critical patients. Both excessive inflammatory response and long-term immunosuppression can lead to the death of sepsis patients. As a key pro-inflammatory cytokine, interleukin-17 (IL-17) plays an important role in the body's inflammatory response and immune system. The signal transduction of IL-17 is a key link in maintaining the body's health and participating in the onset and development of sepsis. This review mainly summarizes and discusses the regulation of IL-17 signal transduction and pathogenic and protective role of IL-17 in sepsis.

Abstract
We studied the effects and mechanisms of action of conophylline in different concentrations in the original in vitro model of myocardial fibrosis (treatment of cardiac fibroblasts isolated form the hearts of newborn rats with angiotensin II). Viability, collagen content, and expression of related protein in cardiac fibroblasts were assessed using the MTT-test, Sircol assay, and Western blotting, respectively. Conophylline markedly protected the cultured cells against the development of angiotensin II-induced fibrosis, which was seen from reduced viability of fibroblasts, decreased collagen content, and down-regulation of the expression of α-smooth muscle actin (α-SMA). Conophylline did not affect the TGF-β pathway altered by angiotensin II, but markedly decreased the level of bone morphogenetic protein-4 (BMP4) enhanced by angiotensin II and BMP4 itself. Conophylline produced no effect on phosphorylation of α-SMA and Smad homologue-1/5/8, the classic BMP4 downstream pathway elements, but reduced the level of c-Jun N-terminal kinase (JNK) elevated by BMP4. Conophylline did not inhibit the development of myocardial fibrosis in the presence of JNK activator anisomycin. Thus, conophylline inhibited angiotensin II-provoked myocardial fibrosis via the BMP4/JNK pathway.

Abstract
Odor emissions from intensive livestock farms have attracted increased attention due to their adverse impacts on the environment and human health. Nevertheless, a systematic summary regarding the characteristics, sampling detection, and control technology for odor emissions from livestock farms is currently lacking. This paper compares the development of odor standards in different countries and summarizes the odor emission characteristics of livestock farms. Ammonia, the most common odor substance, can reach as high as 4100 ppm in the compost area. Sampling methods for point and area source odor emissions are introduced in this paper, and odor analysis methods are compared. Olfactometers, odorometers, and the triangle odor bag method are usually used to measure odor concentration. Odor control technologies are divided into three categories: physical (activated carbon adsorption, masking, and dilution diffusion), chemical (plant extract spraying, wet scrubbing, combustion, non-thermal plasma, and photocatalytic oxidation), and biological (biofiltration, biotrickling, and bioscrubbing). Each technology is elucidated, and the performance in the removal of different pollutants is summarized. The application scopes, costs, operational stability, and secondary pollution of the technologies are compared. The generation of secondary pollution and long-term operation stability are issues that should be considered in future technological development. Lastly, a case analysis for engineering application is conducted.

Abstract
Disordered graphene networks (DGNs) can be regarded as the three-dimensional (3D) assembly of graphene-like fragments at the nanoscale, in which some intrinsic topological features are usually hidden in these formless fragments without clear understanding. Although some high-resolution structural patterns have been observed in pyrolytic carbons and flash graphene experimentally, it is still hard to characterize the topology and texture of DGNs considering continuous 3D connectivity. Toward this end, starting from the annealing process, we herein performed molecular dynamics simulations to investigate the formation and topological structure of DGNs. Three typical stages are found during the formation of DGNs, that is, the formation of polyaromatic fragments, formation of a disordered framework, and further graphitization. The topology of the obtained DGNs was then investigated, including topological defects, stacking behavior, and global curvature. Several typical in-plane and out-of-plane topological defects are found to connect the 3D network of graphene-like layers. The computed X-ray diffraction and angular defects demonstrate that a high-density DGN tends to form a randomly stacked structure with more connections, while a low-density DGN exhibits more bowl-shaped layers and a less distorted curvature. At low annealing temperatures, the local curvature of DGNs is highly distorted, and the structure seems to lack graphitization compared to high-temperature ones.

Abstract
Objective: To summarize the clinical and pathological characteristics of diffuse large B-cell lymphoma of ocular adnexal (OA-DLBCL). Methods: A retrospective case series study. Twenty-three cases of OA-DLBCL were collected in Tianjin Eye Hospital from January 2005 to December 2018. The clinical manifestations and imaging examination results were analyzed. The pathological characteristics and immune subtypes were analyzed with hematoxylin and eosin staining and immunohistochemistry. Eighteen patients completed the follow-up. Overall survival (OS) time was from the date of diagnosis to the date of death or the final follow-up (April 30, 2020). Clinical stages were analyzed by the Ann Arbor classification; Kaplan-Meier plots were used to visualize survival outcomes. The different risk groups were compared using Log-rank test. Results: There were 13 males and 10 females. The median age was 65 years (range, 43 to 82 years). Twenty-two patients had unilateral lymphoma (14 left eyes, 8 right eyes), and one patient had bilateral lymphoma. The OA-DLBCL was in the orbit in 14 patients, in the lacrimal gland in two patients, in both the lacrimal gland and the orbit in three patients, in both the lacrimal sac and the orbit in one patient, in the conjunctiva in one patient, in both the conjunctiva and the orbit in one patient, and in the skin of eyelids in one patient. Imaging examinations showed the tumors were of irregular soft tissue density. MRI showed the tumors were close to the extraocular muscles or ectocinerea. Centroblastic morphology was present in 21 specimens, and 2 specimens had immunoblastic morphology. Six patients were of germinal center B cell-like (GCB) type, and 17 were of non-GCB type. There were 2 patients with double expression of cellular-myelocytomatosis viral oncogene and B-cell lymphoma 2. The follow-up time ranged from 25 to 156 months, and the median follow-up time was 48 months. Five of them had primary OA-DLBCL, and 13 patients had secondary OA-DLBCL. Five patients were at the Ann Arbor clinical stage ⅠE, one was at stage ⅢE, and 12 were at stage ⅣE. During the follow-up, 8 patients survived, and 10 died. The 1-, 3-, and 5-year OS rates were 88.9%, 71.4% and 41.7%, respectively. Log-rank analysis indicated that the Ann Arbor clinical stage and age were related to the OS of OA-DLBCL (χ²=7.448, 8.804; both P<0.01). The gender, tumor size, molecular typing, Ki-67 index, and bone invasion were not related to the OS of OA-DLBCL (all P>0.05). Conclusions: OA-DLBCL mainly occurrs in the elderly population, unilaterally, and in the orbit. Most molecular types are non-GCB subtypes. The Ann Arbor clinical stage and age are associated with prognosis. (Chin J Ophthalmol, 2021, 57: 366-371).

Abstract
Objective: To investigate the clinical characteristics and prognosis of children with acute promyelocytic leukemia (APL) complicated with thrombosis. Methods: The clinical profiles of four APL patients complicated with thrombosis treated at the First Affiliated Hospital of Zhengzhou University between January 2012 and December 2019 were reviewed. Literature search and review covered the China national knowledge infrastructure, Wanfang database, China biology medicine disc and PubMed using the key words of "acute promyelocytic leukemia" and "thrombosis" up to June 2020. Results: Four patients included one male and three females with an age range of 4-13 years. In two patients, thrombosis occurred intracranially, both patients presented with seizure and hemiplegia. In one patient, thrombosis occurred in spleen, the patient presented with severe abdominal pain. In the last patient, thrombosis occurred in liver, the patient presented with abdominal pain, distension and ascites. Thrombosis occurred during the course of retinoic acid treatment in three patients, it occurred before the initiation of the treatment in one patient. Thrombosis was confirmed by imaging examination in all four patients. After thrombolytic and anticoagulation treatment, the vessels were recanalized and the symptoms were alleviated in 3 cases, the fourth patient died of hepatic venous thrombosis. Literature search identified no similar reports in Chinese journals, 11 case reports were found in English journals. In these 15 patients, 9 were male and 6 females with an age range of 3-16 years. Thrombus located in brain in 6 cases, in lower limbs for 3 cases, in liver for 3 cases, in spleen in 2 cases and in coronary artery for 1 case. In 10 cases thrombosis occurred before the induce treatment and in 5 cases occurred during the induction treatment. After surgery, thrombolytic and anticoagulation treatment vascular recanalization was observed in 10 patients, and in those patients, the symptoms were relieved, death occurred in 5 patients, including three patients with hepatic venous thrombosis. Conclusions: Thrombosis may occur before or during the treatment for APL. Both arterial and venous thrombosis may occur in patients with APL. Imaging examination is a reliable method for its diagnosis. After treatment, most patients had good prognosis with recanalization of blood vessels, but the mortality rate was high for patients with hepatic venous thrombosis.

Abstract
OBJECTIVE This study explored the rejuvenation mechanisms of Thai polyherbal medicines using different approaches, including in vitro methods, as well as a well-defined nematode model, Caenorhabditis elegans. METHODS THP-R-SR012 decoction was selected from 23 polyherbal medicines, based on metal-chelating and chain-breaking antioxidant capacities. The influences of this extract on the survival and some stress biomarkers of C. elegans under paraquat-induced oxidative stress were evaluated. Furthermore, lifespan analysis and levels of lipofuscin accumulation were examined in senescent nematodes. The phytochemical profile of THP-R-SR012 was analyzed. RESULTS Supplementation with THP-R-SR012 decoction significantly increased the mean lifespan and reduced the oxidative damage to C. elegans under oxidative stress conditions. Further, THP-R-SR012 supplementation slightly influenced the lifespan and the level of lipofuscin accumulation during adulthood. Antioxidant-related phytochemical constituents of THP-R-SR012 decoction were rutin, naringenin, 3,4-dihydroxybenzoic acid, gallic acid, glycyrrhizic acid, demethoxycurcumin and 18α-glycyrrhetinic acid. CONCLUSION The antioxidant potential of THP-R-SR012 was due to its scavenging properties, its enhancement of antioxidant-related enzyme activities, and the presence of the antioxidant-related compound. These results support the traditional use of THP-R-SR012 decoction as a tonic for nourishing and strengthening the whole body.
