Abstract
Formaldehyde (FA), a carcinogenic oxygenated volatile organic compound, is present ubiquitously in indoor air. As such, it is generally regarded as a critical target for air quality management. The oxidative removal of FA under dark and room-temperature (RT) conditions is of practical significance. A series of ternary nickel-cobalt-manganese oxide-supported platinum catalysts (Pt/NiCoMnO4) have been synthesized for FA oxidative removal at RT in the dark. Their RT conversion values for 50 ppm FA (XFA) at 5,964 h-1 gas hourly space velocity (GHSV) decrease in the following order: 1 wt% Pt/NiCoMnO4 (100 %) > 0.5 wt% Pt/NiCoMnO4 (25 %) > 0.05 wt% Pt/NiCoMnO4 (14 %) > NiCoMnO4 (6 %). The catalytic performance of 1 wt% Pt/NiCoMnO4 has been examined further under the control of various process variables (e.g., catalyst mass, flow rate, relative humidity, FA concentration, time on stream, and molecular oxygen content). The catalytic oxidation of FA at low temperatures (e.g., RT and 60 °C) is accounted for by Langmuir-Hinshelwood mechanism (single-site competitive-adsorption), while Mars van Krevelen kinetics is prevalent at higher temperatures. In situ diffuse-reflectance infrared Fourier-transform spectroscopy reveals that FA oxidation proceeds through a series of reaction intermediates such as DOM, HCOO-, and CO32-. Based on the density functional theory simulations, the unique electronic structures of the nearest surface atoms (platinum and nickel) are suggested to be responsible for the superior catalytic activity of Pt/NiCoMnO4.

Abstract
OBJECTIVES To uncover the clinical course of fetal isolated non-immune mediated second-degree AVB and determine the factors associated with the spontaneous recovery for fetal non-immune second-degree atrioventricular block (AVB). METHODS A total of 20 fetuses with isolated, non-immune mediated second-degree AVB were prospectively recruited between 2014 and 2022. These fetuses were divided into the spontaneous recovery group (n=12) and the non-spontaneous recovery group (n=8). Maternal and fetal basic characteristics, intrauterine and postnatal outcomes were compared between groups. RESULTS Twelve fetuses restored 1:1 atrioventricular conduction in utero and did not recur during the postnatal follow-up period. The residual eight fetuses maintained as second-degree AVB and six of them were aborted due to parental request in utero. Of the two live children with second-degree AVB, one of them progressed to complete AVB at the latest follow up at the age of 34 months, but without any symptoms, heart enlargement or dysfunction. The residual one progressed to complete AVB and was finally diagnosed with type 2 long-QT syndrome. Fetuses in the spontaneous recovery group presented with earlier gestational age at diagnosis (20.0[17.0-26.0] vs. 24.5[18.0-35.0] weeks, p=0.004) and higher atrial rate (147[130-160] vs 138.00[125.00-149.00] bpm, p=0.006) in comparison with the non-spontaneous recovery group. A cut-off value of 22.5 weeks of gestational age and 144 bpm of atrial rate at diagnosis could predict the failure of spontaneous recovery, with sensitivities of 87.5%, 75%, and specificities of 92.0%, 87.5%, respectively. CONCLUSIONS The outcome of fetal non-immune second-degree AVB was favorable. Earlier gestational age at diagnosis and higher atrial rate were related to spontaneous reversion for isolated non-immune-mediated second-degree AVB. However, prenatal gene test should be performed for those with persistent AVB to exclude the heritable disorders including LQTS. These findings may provide important references for clinical management and prenatal counseling. This article is protected by copyright. All rights reserved.

Abstract
Titanium dioxide-supported platinum (Pt@TiO2) is regarded as a highly efficient catalyst to degrade various volatile organic compounds (VOCs). To learn more about the hybrid adsorption/catalysis process of Pt@TiO2, the adsorption behavior of FA onto Pt@TiO2 was studied both as single and as multicomponent phases (FA plus four aromatic compounds of benzene, toluene, m-xylene, and styrene (BTXS) through the control of key process variables (e.g., VOCs concentration, relative humidity (RH) levels, and dosage). Moreover, the adsorption performance of Pt@TiO2 against FA was evaluated in terms of key performance metrics such as breakthrough volume (BTV), partition coefficient (PC), and adsorption capacity (Q). The doping of TiO2 with Pt metal ions was demonstrated as an efficient option to enhance the FA adsorption capacity (e.g., by 50 % higher than pristine TiO2) with increased OH (OII) surface active sites and surface porosity. However, the co-presence of BTXS and water vapor greatly reduced its adsorption affinity for FA vapor (e.g., by 2 to 3 folds of magnitude) due to their competitive inhibition on the adsorption interaction. According to the kinetic and isotherms analysis, a complex, multilayered physicochemical process appears to govern the overall adsorption of FA molecules onto Pt@TiO2 surface. Overall, the outcomes of this work are helpful to verify the enhanced removal potential of Pt@TiO2 against FA through sequential adsorption and catalytic reaction mechanisms.

Abstract
In this work, a ratiometric fluorometric sensor based on nickel nanoclusters (NiNCs)-europium complex (NiNCs-Eu3+) was constructed for the highly selectivity detection of tetracyclines (TCs) in water samples. In the presence of TCs, the blue fluorescence of the sensor NiNCs-Eu3+ was quenched at 430 nm and the characteristic red fluorescence of Eu3+-TCs appeared at 620 nm because of the combined help of inner filter effect (IFE) and antenna effect. Under the optimized conditions (100 mM Eu3+ (100 µL); temperature (25℃); reaction time (10 min), HEPES buffer solution (pH = 7.0)), the sensor offered a wide detection range of tetracycline (TC) and oxytetracycline (OTC) from 0.1 to 50 μM with the detection limit (LOD) of 25 nM and 21 nM, respectively. Moreover, the sensor was able to detect of TC and OTC in tap and lake water with high recovery rate (89.10%-97.60%). In addition, the portable paper-based sensor was constructed using filter paper embedded with NiNCs-Eu3+. The distinct fluorescent color of the paper-based sensor varied from bright blue to red against different concentrations of TC and OTC. These above findings demonstrated the potential for wide application of as-prepared ratio metric fluorescence sensor for visual detection of TCs in water samples.

Abstract
Formaldehyde (HCHO: FA) is one of the most abundant but hazardous gaseous pollutants. Transition metal oxide (TMO)-based thermocatalysts have gained much attention in its removal due to their excellent thermal stability and cost-effectiveness. Herein, a comprehensive review is offered to highlight the current progress in TMO-based thermocatalysts (e.g., manganese, cerium, cobalt, and their composites) in association with the strategies established for catalytic removal of FA. Efforts are hence made to describe the interactive role of key factors (e.g., exposed crystal facets, alkali metal/nitrogen modification, type of precursors, and alkali/acid treatment) governing the catalytic activity of TMO-based thermocatalysts against FA. Their performance has been evaluated further between two distinctive operation conditions (i.e., low versus high temperature) based on computational metrics such as reaction rate. Accordingly, the superiority of TMO-based composite catalysts over mono- and bi-metallic TMO catalysts is evident to reflect the abundant surface oxygen vacancies and enhanced FA adsorptivity of the former group. Finally, the present challenges and future prospects for TMO-based catalysts are discussed with respect to the catalytic oxidation of FA. This review is expected to offer valuable information to design and build high performance catalysts for the efficient degradation of volatile organic compounds.

Abstract
Aluminum is a relatively inexpensive and abundant metal for the mass production of metal-organic frameworks (MOFs). Aluminum-based MOFs (Al-MOFs) have drawn a good deal of research interest due to their unique properties for diverse applications (e.g., excellent chemical and structural stability). This review has been organized to highlight the current progress achieved in the synthesis/functionalization of Al-MOF materials with the special emphasis on their sensing application, especially toward metal ion pollutants in the liquid phase. To learn more about the utility of Al-MOF-based sensing systems, their performances have been evaluated for diverse metallic components in reference to many other types of sensing systems (in terms of the key quality assurance (QA) criteria such as limit of detection (LOD)). Finally, the challenges and outlook for Al-MOF-based sensing systems are discussed to help expand their real-world applications.

Abstract
A new type of photonic crystal gel molecularly imprinted sensor (MIPHs) was synthesized for the visible chiral recognition of amino acids. The color of MIPHs was changed from green to red when it exposured to various l-pyroglutamic acid concentration (0.05-1.0mmoL/L). Thanks to sensitive reflectance of photonic crystal and high selectivity of MIPs, the constructed MIPHs exhibited good performance towards l-pyroglutamic acid in terms of fast response time (3 min) and low detection limit (LOD) (2.4 μmol/L). Besides, MIPHs was found to have good selectivity toward l-pyroglutamic acid in the presence of interference group with similar structures such as d-pyroglutamic acid, l-tryptophan, l-phenylalanine, and l-proline. In light of these findings, the MIPHs can be used for highly selective recognition of l-pyroglutamic acid. It is expected that our work is able to provide a new roadmap for the chiral identification and separation of amino acids.

Abstract
Chemical sensors that can detect volatile organic compounds (VOCs) are the subject of extensive research efforts. Among various sensing technologies, molecularly imprinted polymers (MIPs) are regarded as a highly promising option for their detection with many advantageous properties, e.g., specific binding-site for template molecules, high recognition specificity, ease of preparation, and chemical stability. This review covers recent advances in the sensing application of MIPs toward various types of VOCs (e.g., aliphatic and aromatic compounds). Particular emphasis has been placed on multiple approaches to the synthesis of MIP-based VOC sensors in association with their performance and sensing mechanisms. Current challenges and opportunities for new VOC-sensing applications are also discussed based on MIP technology.

Abstract
Optical thermometry based on fluorescence intensity ratio (FIR) technology has several advantages for industrial and medical applications such as remote signaling, non-invasiveness, and excellent spatial resolution. Here, an approach to the construction of luminescent thermometers is proposed based on high-temperature solid-state reactions through doping of rare earth (RE) elements (e.g., samarium (Sm3+) or europium (Eu3+)) into Ca2Y0.97Bi0.03SbO6 (CYBS) phosphors. The tuning of the CYBS:Eu3+ and CYBS:Sm3+ ratios in the phosphors provided a wide range of color changes from purplish blue to red and from purplish blue to pink, respectively. The superiority of optical thermometer is validated by higher values of absolute sensitivity (Sa) and relative sensitivity (Sr). As such, both phosphors exhibit excellent temperature sensing performance with Sa/Sr values (at 483 K) of 4.945 × 10-2/0.968 × 10-2 K-1 (CYBS:0.05Eu3+) and 2.964 × 10-2/0.864 × 10-2 K-1 (CYBS:0.05 Sm3+). Thus, RE-doped CYBS materials with color tuning properties and superior temperature sensing performance are recommended for the construction of novel luminescent optical thermometers.

Abstract
Mycotoxin is toxic secondary metabolite formed by certain filamentous fungi. This toxic compound can enter the food chain through contamination of food (e.g., by colonization of toxigenic fungi on food). In light of the growing concerns on the health hazards posed by mycotoxins, it is desirable to develop reliable analytical tools for their detection in food products in both sensitive and efficient manner. For this purpose, the potential utility of molecularly imprinted polymers (MIPs) has been explored due to their meritful properties (e.g., large number of tailor-made binding sites, sensitive template molecules, high recognition specificity, and structure predictability). This review addresses the recent advances in the application of MIPs toward the sensing of various mycotoxins (e.g., aflatoxins and patulin) along with their fabrication strategies. Then, performance evaluation is made for various types of MIP- and non-MIP-based sensing platforms built for the listed target mycotoxins in terms of quality assurance such as limit of detection (LOD). Further, the present challenges in the MIP-based sensing application of mycotoxins are discussed along with the future outlook in this research field.

Abstract
We demonstrate record ∼0.9% efficiencies for optical conversion to narrowband (<1% relative bandwidth) terahertz (THz) radiation by strongly cascaded difference frequency generation. These results are achieved using a novel, to the best of our knowledge, laser source, customized for high efficiencies, with two narrow spectral lines of variable separation and pulse duration (≥250 ps). THz radiation generation in 5% MgO-doped periodically poled lithium niobate (PPLN) crystals of varying poling period was explored at cryogenic and room temperature operation as well as with different crystal lengths. This work addresses an increasing demand for high-field THz radiation pulses which has, up to now, been largely limited by low optical-to-THz radiation conversion efficiencies.

Abstract
It is generally acknowledged that calcium lactate (ca-lactate) fortification of soymilk to
achieve the equivalent calcium level in cow’s milk (1.2 mg/g) causes instability in
soymilk. In order to produce acceptable calcium-enriched soymilk with great stability,
three different kinds of chelating agents were added, namely tripotassium citrate (TPC),
trisodium citrate (TSC), and sodium hexametaphosphate (SHMP). In this study, the
addition of ca-lactate was found to reduce the pH (6.62 to 5.37) and increase the particle
diameter (268.66 to 1,222.81 nm) and sedimentation (0.19 to 8.75%) of soymilk.
Meanwhile, the addition of TPC and TSC produced calcium-enriched soymilks with
smaller particle diameter (295.21-452.22 nm and 297.61-461.80 nm) and lower
sedimentation levels (0.25-1.55% and 0.26-1.58%). The pH of calcium-enriched soymilk
was also increased when both chelating agents were added. The application of SHMP as a
chelating agent was not as effective as TPC and TSC because the particle diameter
(527.98-703.40 nm) and sedimentation level were still relatively higher (4.24-5.68%) than
the unfortified soymilk. Even though both TPC and TSC showed no significant difference
(P>0.05) in stability, the sensory evaluation showed different results. Soymilk with TSC
added was saltier and sourer than samples with TPC added. The study recommends the
use of TPC as the chelating agent in soymilk enriched with ca-lactate.

Abstract
A recently developed compact 3 T (C3T) MRI scanner with high performance gradients [1, 2] has a dedicated radiofrequency (RF) transmit coil that exposes only the head, neck and a small portion of the upper body region during head-first scanning. Due to the unique coil geometry and patient positioning, the established SAR model used for a conventional whole-body scanner cannot be directly translated to the C3T. Here a specific absorption rate (SAR) estimation and validation framework was developed and used to implement a dedicated and accurate SAR prediction model for the C3T. Two different SAR prediction models for the C3T were defined and evaluated: one based on an anatomically derived exposed mass, and one using a fixed anatomical position located caudally to the RF coil to determine the exposed mass. After coil modeling and virtual human body simulation, the designed SAR prediction model was implemented on the C3T and verified with calorimetry and in vivo scan power monitoring. The fixed-demarcation exposed mass model was selected as appropriate exposed mass region to accurately estimate the SAR deposition in the patient on the C3T.

Abstract
OBJECTIVE The competing endogenous RNA (ceRNA) presents a comprehensive regulatory network among lncRNAs, miRNAs and mRNA. The ceRNA provides significant information in understanding the pathology of cancer. This study aimed to explore a lncRNA-associated ceRNA network for predicting the overall survival of patients with hepatocellular carcinoma (HCC). MATERIALS AND METHODS In this study, RNA-sequencing data of HCC were downloaded from The Cancer Genomes Atlas (TCGA) database. The module-trait relationship was analyzed with Weighted gene co-expression network analysis (WGCNA). The key module associated with tumor was identified, as well as the involved lncRNAs, mRNAs and miRNAs. The preliminary ceRNA network was constructed with Cytoscape. The survival analysis was further performed to screen survival-relevant lncRNAs, mRNAs and miRNAs, and then the survival-associated ceRNA network was reconstructed. RESULTS Eventually, 5 lncRNAs, 10 miRNAs, and 25 mRNAs were included in the reconstructed ceRNA network. CONCLUSIONS The identified lncRNAs were promising candidate biomarkers in HCC diagnosis and therapeutics. This analysis process was effective to construct ceRNA network. The result will be conductive to explore the significant lncRNAs and regulatory mechanism.

Abstract
Precise quantitative delineation of tumor hypoxia is essential in radiation therapy treatment planning to improve the treatment efficacy by targeting hypoxic sub-volumes. We developed a combined imaging system of positron emission tomography (PET) and electron para-magnetic resonance imaging (EPRI) of molecular oxygen to investigate the accuracy of PET imaging in assessing tumor hypoxia. The PET/EPRI combined imaging system aims to use EPRI to precisely measure the oxygen partial pressure in tissues. This will evaluate the validity of PET hypoxic tumor imaging by (near) simultaneously acquired EPRI as ground truth. The combined imaging system was constructed by integrating a small animal PET scanner (inner ring diameter 62 mm and axial field of view 25.6 mm) and an EPRI subsystem (field strength 25 mT and resonant frequency 700 MHz). The compatibility between the PET and EPRI subsystems were tested with both phantom and animal imaging. Hypoxic imaging on a tumor mouse model using 18F-fluoromisonidazole radio-tracer was conducted with the developed PET/EPRI system. We report the development and initial imaging results obtained from the PET/EPRI combined imaging system.

Abstract
OBJECTIVE The aim of this study was to investigate whether microRNA-1286 could inhibit the osteogenic differentiation of human marrow mesenchymal stem cells (hMSCs) by regulating FZD4 expression and promoting the progression of osteoporosis. PATIENTS AND METHODS Quantitative Real Time-Polymerase Chain Reaction (qRT-PCR) was used to detect the expression of microRNA-1286 in the serum of patients with osteoporosis. Meanwhile, microRNA-1286 expression in different stages of osteogenic differentiation of hMSCs was measured by qRT-PCR as well. After overexpression of microRNA-1286 and FZD4 in hMSCs, the mRNA expression levels of microRNA-1286, alkaline phosphatase (ALP), RUNX2 and osteocalcin (OCN) were detected by qRT-PCR. The protein expression levels of RUNX2 and OCN were detected by Western blot. Meanwhile, alkaline phosphatase (ALP) activity and expression in cells were examined using ALP assay kit and ALP staining method, respectively. Cell mineralized nodules were detected through the alizarin red staining test. Bioinformatics method was used to predict the binding site of microRNA-1286 to FZD4. Subsequent luciferase reporter gene assay was performed to verify whether microRNA-1286 could combine with FZD4. After overexpression or knockdown of microRNA-1286, the mRNA and protein expressions of FZD4 were analyzed using qRT-PCR and Western blot assay, respectively. After the simultaneous overexpression of microRNA-1286 and FZD4 in hMSCs, the mRNA expression levels of ALP, RUNX2 and OCN, ALP activity and content, and cell mineralization ability were successively examined. RESULTS The expression of microRNA-1286 in the serum of patients with osteoporosis was significantly higher than that of the normal population. Meanwhile, microRNA-1286 expression decreased with the increase of osteogenic differentiation days of hAMSCs. After the overexpression of microRNA-1286, ALP, RUNX2, and OCN levels, ALP activity, RUNX2, and OCN protein levels, as well as mineralized nodule formation were significantly reduced. However, results were reversed when FZD4 was simultaneously up-regulated. Luciferase reporter gene assay results verified that microRNA-1286 could bind to FZD4. After the overexpression of microRNA-1286, the mRNA and protein expressions of FZD4 were found significantly down-regulated. However, results were reversed after knocking down microRNA-1286. Furthermore, the simultaneous overexpression of microRNA-1286 and FZD4 could counteract the inhibitory effect of over-expression of microRNA-1286 on osteogenic differentiation of hMSCs. CONCLUSIONS MicroRNA-1286 can regulate FZD4 expression and inhibit osteogenic differentiation of hMSCs, thereby promoting the development of osteoporosis.

Abstract
We present the development of a PET insert system for potential simultaneous PET/MR imaging using a 9.4 T small animal MRI scanner to test our system. The detectors of the system adopt a strip-line based multiplexing readout method for SiPM signals. In this readout, multiple SiPM outputs in a row share a common strip-line. The position information about a hit SiPM is encoded in the propagation time difference of the signals arriving at the two ends of the strip-line. The use of strip-lines allows us to place the data acquisition electronics remotely from the detector module to greatly simplify the design of the detector module and minimize the mutual electromagnetic interference. The prototype is comprised of 14 detector modules, each of which consists of an 8x4 LYSO scintillator array (each LYSO crystal is 3x3x10 mm3) coupled to two units of Hamamatsu MPPC arrays (4x4, 3.2 mm pitch) that are mounted on a strip-line board. On the strip-line board, outputs of the 32 SiPMs are routed to 2 strip-lines so that 16 SiPM signals share a strip-line. The detector modules are installed inside a plastic cylindrical supporting structure with an inner and outer diameter of 60 mm and 115 mm, respectively, to fit inside a Bruker BioSpec 9.4 Tesla MR scanner. The axial field of view of the prototype is 25.4 mm. The strip-lines were extended by using 5-meter cables to a sampling data acquisition (DAQ) board placed outside the magnet. The detectors were not shielded in the interest of investigating how they may affect and be affected by the MRI. Experimental tests were conducted to evaluate detection performance, and phantom and animal imaging were carried out to assess the spatial resolution and the MR compatibility of the PET insert. Initial results are encouraging and demonstrate that the prototype insert PET can potentially be used for PET/MR imaging if appropriate shielding will be implemented for minimizing the mutual interference between the PET and MRI systems.

Abstract
AIMS Although comammox have been discovered in a variety of ecosystems, there are few studies in urban lakes. This paper attempted to confirm whether this ammonia-oxidizing microbe exists in urban lakes and to determine the factors influencing its existence. METHODS AND RESULTS This study investigated the diversity and abundance of comammox bacteria in sediments of a typical urban lake in China, and their ecological relationship with other ammonia-oxidizing micro-organisms. The phylogenetic analysis indicated that comammox clade A existed in the sediment of Lake Donghu, and the comammox bacteria co-existed with ammonia-oxidizing archaea (AOA), ammonia-oxidizing bacteria (AOB) and anaerobic ammonia-oxidizing (anammox) bacteria in the sediment of this lake. The abundances of the ammonia monooxygenase subunit A (amoA) genes for comammox, AOA, AOB and anammox 16S rRNA were 2·43 × 108 , 1·07 × 108 , 3·24 × 107 and 3·21 × 1011 copies per gram dry sediment respectively. Moreover, the amoA gene abundance of comammox was positively correlated with that of AOA and AOB. The redundancy analysis showed that the abundance of the comammox amoA gene was negatively correlated with the concentration of main indicators for nitrogen status in both the sediment and the water column, indicating that eutrophication may inhibit the growth of comammox bacteria. CONCLUSIONS Comammox bacteria play an important ecological role in the nitrogen cycle of urban lake sediments. SIGNIFICANCE AND IMPACT OF THE STUDY Our results indicated comammox bacteria were widespread in urban lakes and eutrophication may inhibit their growth.

Abstract
We generate temporally modulated optical pulses with a beat frequency of 255 GHz, a duration of 360 ps, and a repetition rate of 2 MHz. The temporal envelope, beat frequency, and repetition rate are computer-programmable. A frequency comb serves as a phase and frequency reference for the locking of two laser lines. The system enables beat frequencies that are adjustable in steps of the frequency comb's repetition rate and exhibit Hz-level precision and accuracy. We expect the optical beat pulses to be well suited for versatile multi-cycle terahertz-wave generation with controllable carrier-envelope phase. We demonstrate that the inherent synchronization of the frequency comb's ultra-short pulse train and the synthesized optical beat (or later the multi-cycle terahertz) pulses enables rapid and phase-sensitive sampling of such pulses.

Abstract
OBJECTIVE To analyze the clinical characteristics of patients with hematological tumor or disease before and after reversible posterior leukoen-cephalopathy syndrome (RPLS). METHODS Five patients were both from Peking University First Hospital Pediatric Hematology-oncology Department in the period from March 2012 to March 2017. The gender, age, BMI, underlying diseases, with or without renal damage, hypertension family history, clinical manifestations of convulsions, hemoglobin, and blood pressure, serum sodium levels before and after convulsion, and other data of the children with RPLS were retrospectively analyzed. In the meantime, we followed up the five patients for 6 months to 66 months, kept a watchful eye on their original condition and the recovery of symptoms and signs of the nervous system. The relevant literature was reviewed. RESULTS All of the subjects were females in school-age or pre-school age. The underlying diseases were malignant tumor associated with renal involvement or on one side of nephrectomy in 4 of these subjects, while the other one was refractory autoimmune hemolytic anemia. All of the subjects suffered from mild or moderate anemia. The day before RPLS occurred they received chemotherapy made up with cyclophosphamide, vincristine, and actinomycin-D, or the therapy with cyclosporin A and glucocorticoid. The clinical manifestations were afebrile convulsion after getting up in the mooring or in the afternoon. We observed elevation of blood pressure and cutting down of serum sodium compared with themselves. All of the cases recovered soon after management with diazepam, furosemide and amlodipine besylate. Four of them had a good outcomes and did not remain any sequela, while only one girl became childish in emotion and behavior, and then returned gradually to normal two years later. However, by long-term follow-up, the elevation of blood pressure was mainly reviewed in literature. CONCLUSION The patients attacked by RPLS, with hematology or oncology cases, could have the underlying disease of renal damage and anemia. Blood pressure elevation and serum sodium falling down at the same time may play an important role during the occurrence of RPLS. Remaining stable of blood pressure and electrolyte level together will possibly reduce or mitigate RPLS.

Abstract
OBJECTIVE To investigate the expression level of serum microRNA-21 (miR-21) in 69 patients with osteosarcoma, to analyze the changes in miR-21 expression in the serum and tumor tissues before and after chemotherapy in patients with osteosarcoma, and to investigate the relationship between the expression of serum miR-21 in patients with osteosarcoma and chemosensitivity. PATIENTS AND METHODS Real-time polymerase chain reaction (RT-PCR) was used to detect the expression level of serum miR-21 in 69 patients with osteosarcoma before and after chemotherapy, and analyze the relationship between the expression of miR-21 with tumor necrosis grading and chemosensitivity. The expression level of programmed cell death protein 4 (PDCD4) in tumor tissues of patients with osteosarcoma before and after chemotherapy was detected by Western blot. RESULTS The expression level of serum miR-21 in patients with osteosarcoma was significantly higher than that in normal control subjects. The expression of serum miR-21 before and after chemotherapy was positively correlated with the expression of miR-21 in the corresponding tissues. In the group where chemotherapy was effective (the effective group), expression levels of miR-21 in patients with osteosarcoma before and after chemotherapy were significantly different. After chemotherapy, the expression level of target genes of miR-21 was increased, and the follow-up results showed that the 5-year survival rate was relatively higher after surgery. CONCLUSIONS The expression level of serum miR-21 in patients with osteosarcoma is closely related to the therapeutic effects of osteosarcoma, which can be used as one of the potential biomarkers and therapeutic targets for the diagnosis and prediction of osteosarcoma.

Abstract
DiGeorge syndrome is the most common chromosome microdeletion disease. The classical complications include congenital heart disease, hypothyroidism, immunodeficiency, facial abnormalities, and hypocalcemia. According to whether there is an absence or hypoplasia of the thymus, DiGeorge syndrome can be divided into two types, complete DiGeorge syndrome and partial DiGeorge syndrome. The patient was a female born with congenital heart disease, facial abnormalities and cleft palate. When the patient went to school, she had learning difficulty and had problems in communication and personal social behavior. Breath-holding occurred when she was 6 years old. She got infections about 2-3 times a year, which was easy to be cured each time. Chromosome microdeletion test of peripheral blood showed the classical 22q11.2 microdeletion, and no evidence showed that she has thymus absence, thus her disease was diagnosed as partial DiGeorge syndrome. When the patient was 6 years old, the blood routine test showed slight thrombocytopenia, and reexaminations after that indicated the similar result. When 9 years old, she was found with anemia and severe thrombocytopenia. At the age of 10, the patient was admitted to our hospital, complaining of petechia in the body and mucous of mouth. According to the various examinations results, doctors eventually considered the situation as an autoimmune disorder phenomenon. After being treated by pulse-dose methylprednisolone for three days, the bleeding ceased. Then the patient orally took prednisone acetate and pulse-dose cyclophosphamide, however the thrombocyte and hemoglobin levels had not been back to a normal range. But when the dose of prednisone acetate was reduced, the blood platelet count declined again while the hemoglobin kept normal. The long-term follow-up of this case lasted for more than 20 years. Until now, the patient is taking orally prednisone acetate as a maintainance treatment, and the anemia has been improved since, but thrombocytopenia still exists. The mechanism of DiGeorge syndrome in combination with immunodeficiency is still unclear. The most likely reason is that this phenomenon has some relationship with the dysfunction of the thymus and finally had an effect on the function of T cells. The clinical manifestation is always stubborn and need treatment and follow-up visit for a long time.
