Abstract
Although the pathogenesis of acute myeloid leukemia (AML) is still unknown, accumulating evidence has revealed that immune response plays a vital part in the pathogenesis. Here, we investigated the involvement of 21 single nucleotide polymorphisms (SNPs) of immunorelated genes, including cytokines [interleukin (IL)-2, IL-4, IL-9, IL-12A, IL-22, interferon (IFN-α) and transforming growth factor (TGF)-β1], transcriptional regulatory genes (TBX21, STAT1, STAT3, STAT5B, STAT6, GATA3, FOXP3 and IRF4) and others (IL2RA, IL6R, NFKBIA) in 269 AML in-patients and 200 healthy controls. Furthermore, we analyzed the relationship between the SNPs and clinical characteristics. Immunorelated SNP genotyping was performed on the Sequenom MassARRAY iPLEX platform. All the SNPs in healthy controls were consistent with Hardy-Weinberg equilibrium. All final P-values were adjusted by Bonferroni multiple testing. Our results showed that IL-22 (rs2227491) was significantly associated with the white blood cell (WBC) counts. Signal transducer and activator of transcription 5B (STAT-5B) (rs6503691) showed a close relationship with the recurrent genetic abnormalities in patients with AML. We verified the negatively independent effect of age and risk of cytogenetics on overall survival (OS). More importantly, the GG genotype of IL-12A (rs6887695) showed a negative impact on AML prognosis independently. Furthermore, the relative expression of IL-12 was decreased in GG genotype, no matter under a co-dominant or recessive model. However, no correlation was observed between the SNPs mentioned above and disease susceptibility, risk stratification and survival. Our findings suggest that immunorelated gene polymorphisms are associated with prognosis in AML, which may perform as novel inspection targets for AML patients.

Abstract
BACKGROUND AND PURPOSE Previous studies have shown that diffusion tensor imaging suggests a diffuse loss of white matter integrity in people with white matter hyperintensities or lacunes. The purpose of this study was to investigate whether the presence of cerebral microbleeds and their distribution are related to the integrity of white matter microstructures. MATERIALS AND METHODS The study comprised 982 participants who underwent brain MR imaging to determine microbleed status. The cross-sectional relation between microbleeds and the microstructural integrity of the white matter was assessed by 2 statistical methods: a multilinear regression model based on the average DTI parameters of normal-appearing white matter and Tract-Based Spatial Statistics analysis, a tract-based voxelwise analysis. Fiber tractography was used to spatially describe the microstructural abnormalities along WM tracts containing a cerebral microbleed. RESULTS The presence of cerebral microbleeds was associated with lower mean fractional anisotropy and higher mean diffusivity, axial diffusivity, and radial diffusivity, and the association remained when cardiovascular risk factors and cerebral small-vessel disease markers were further adjusted. Tract-Based Spatial Statistics analysis indicated strictly lobar cerebral microbleeds associated with lower fractional anisotropy, higher mean diffusivity, and higher radial diffusivity in the internal capsule and corpus callosum after adjusting other cerebral small-vessel disease markers, while only a few voxels remained associated with deep cerebral microbleeds. Diffusion abnormalities gradients along WM tracts containing a cerebral microbleed were not found in fiber tractography analysis. CONCLUSIONS Cerebral microbleeds are associated with widely distributed changes in white matter, despite their focal appearance on SWI.

Abstract
Objective: To observe the effects of pyrroloquinoline quinine (PQQ) on the mitochondrial function and cell survival of rat bone marrow mesenchymal stem cells (BMSCs) under oxidative stress, and to explore its mechanism. Methods: BMSCs of rats were cultured in vitro with Dulbecco's minimum essential medium/F12 medium containing fetal bovine serum in the volume fraction of 10% (hereinafter referred to as normal medium). The rat BMSCs of third to fifth passages in logarithmic growth phase were selected for the following experiments. (1) The cells were divided into normal control group, normal control+ PQQ group, hydrogen peroxide (H(2)O(2)) alone group, and H(2)O(2)+ PQQ group. The cells in normal control group were cultured in normal medium for 24 hours; the cells in normal control+ PQQ group were cultured in normal medium containing 100 μmol/L PQQ for 24 hours; the cells in H(2)O(2) alone group were cultured in normal medium containing 200 μmol/L H(2)O(2) for 24 hours; the cells in H(2)O(2)+ PQQ group were pre-incubated with normal medium containing 100 μmol/L PQQ for 2 hours, and then with H(2)O(2) added to the concentration of 200 μmol/L and cultured for 24 hours. The cell morphology of each group was observed under the inverted phase contrast microscope, and the cell survival rate was detected by cell count kit 8 method. (2) Five batches of cells were collected, and the cells of each batch were divided into normal control group, H(2)O(2) alone group, and H(2)O(2)+ PQQ group. The cells in each group received the same treatment as that in the corresponding group of experiment (1). After 24 hours of culture, one batch of cells was collected for apoptosis detection by flow cytometry, and the apoptosis rate was calculated. One batch of cells was subjected to mitochondrial membrane potential assay and JC-1 fluorescent staining observation using the JC-1 mitochondrial membrane potential detection kit and the inverted phase contrast fluorescence microscope, respectively. One batch of cells was collected for mitochondrial morphology observation under the transmission electron microscope. One batch of cells was subjected to catalase (CAT) and superoxide dismutase (SOD) activity assay by CAT activity assay kit and SOD activity assay kit, respectively. One batch of cells was subjected to Western blotting for determination of protein level of Epac1, adenine monophosphate activated protein kinase (AMPK), phosphorylated AMPK, cysteinyl aspartate-specific proteinase 3 (caspase-3), and cleaved caspase-3, and the phosphorylation level of AMPK and cleaved caspase-3/caspase-3 ratio were calculated. Six replicates were measured in each group for each index except for morphological observation. Data were statistically analyzed with one-way analysis of variance and independent sample equal variance t test. Results: (1) After 24 hours of culture, compared with those in normal control group (the cell survival rate was set to 100.0%), there was an increase in cell vacuole and a decrease in cell number in H(2)O(2) alone group, and the cell survival rate was significantly reduced to (74.3±2.9)% (t=6.39, P<0.01). Compared with those in H(2)O(2) alone group, the cell morphology of H(2)O(2)+ PQQ group was significantly improved, and the cell survival rate was significantly increased to (116.9±4.2)% (t=6.92, P<0.01); the cell survival rate in normal control+ PQQ group was (101.2±1.1)%, close to that of control group (t=1.06, P>0.05). (2) After 24 hours of culture, compared with (13.6±1.0)% in normal control group, the apoptosis rate of cells in H(2)O(2) alone group was significantly increased to (37.1±2.0)% (t=10.57, P<0.01). Compared with that in H(2)O(2) alone group, the apoptosis rate of cells in H(2)O(2)+ PQQ group was significantly declined to (17.0±0.7)% (t=9.49, P<0.01). (3) After 24 hours of culture, compared with those in normal control group, the mitochondrial membrane potential of cells in H(2)O(2) alone group was depolarized, the JC-1 fluorescent dye mainly existed in the cytoplasm in the form of monomer, which emitted green fluorescence, and a significant decrease in mitochondrial membrane potential was shown (t=4.18, P<0.01). Compared with those in H(2)O(2) alone group, the mitochondrial membrane potential of cells in H(2)O(2)+ PQQ group was increased to normal level (t=4.43, P<0.01), and the JC-1 fluorescent dye accumulated in mitochondria following the polarized mitochondrial membrane potential and emitted red fluorescence. (4) After 24 hours of culture, compared with that in normal control group, the mitochondrial structure of cells in H(2)O(2) alone group was disordered, with disappeared mitochondrial cristae and decreased mitochondrial matrix density. Compared with that in H(2)O(2) alone group, the mitochondrial structure of cells in H(2)O(2)+ PQQ group was regular and intact, with clearly visible mitochondrial cristae and increased mitochondrial matrix density. (5) After 24 hours of culture, compared with those in normal control group, the CAT activity of cells in H(2)O(2) alone group was significantly increased (t=4.54, P<0.05), and the SOD activity was significantly decreased (t=3.93, P<0.05). Compared with those in H(2)O(2) alone group, the CAT activity of cells in H(2)O(2)+ PQQ group was obviously increased (t=8.65, P<0.01), while there was no significant change in the SOD activity (t=0.72, P>0.05). (6) After 24 hours of culture, compared with those in normal control group, the protein expression of Epac1 of cells in H(2)O(2) alone group was significantly decreased (t=4.67, P<0.01), while the AMPK phosphorylation level and the cleaved caspase-3/caspase-3 ratio were significantly increased (t=7.88, 3.62, P<0.01). Compared with those in H(2)O(2) alone group, the protein expression of Epac1 and the AMPK phosphorylation level of cells in H(2)O(2)+ PQQ group were both significantly increased (t=4.34, 16.37, P<0.01), while the cleaved caspase-3/caspase-3 ratio was significantly declined (t=3.17, P<0.05). Conclusions: Pretreatment with PQQ can improve the mitochondrial function, reduce cell apoptosis rate, and enhance cell survival rate of rat BMSCs under oxidative stress, which may be related to the up-regulation of Epac1 protein expression, activation of AMPK signaling pathway, and down-regulation of cleaved caspase-3 protein level.

Abstract
Introduction
Narcolepsy is a chronic sleep disorder that can affects significantly patient functioning, involving social, work, and affective life. At present, many drugs have been developed to treat narcolepsy efficiently. But there is no Chinese version of Narcolepsy Severity Scale (NSS) available yet, for that the aim of this study is to translate the NSS into Chinese and evaluate reliability and validity of the NSS in adult patients with narcolepsy type 1 (NT1).
Methods
NSS was translated according to the standard procedures of double-back translation and cross-cultural adaptation steps. The NSS was administered to 62 adult patients (42 males, 20 females; mean age 34 years; range 19 to 67 years) with NT1 from April 2019 to December 2019. The validity of the scale was assessed by the exploratory factor analysis, discriminant validity and convergent validity. The reliability was assessed by the Cronbach’s α coefficient and test-retest reliability.
Results
Three common factors were extracted and 15 items explained 57.4% of the total variance. Cronbach’s α coefficient for total scale was 0.767 and Cronbach’s α for three dimensions ranged from 0.729 to 0.787. Scores were significant difference between treated and untreated group in dependent samples (p=0.036), but no differences in the independent samples (p>0.05). The NSS had good correlations with Epworth Sleepiness Scale (r=0.302, p=0.017) and Insomnia Severity Index (r=0.526, p=0.000). The NSS showed good test-retest reliability (r=0.72, p=0.029).
Conclusion
The Chinese version of NSS was proved to be valid and reliable and can be used to evaluate the severity and consequences of symptoms in Chinese adult patients with NT1.

Abstract
Abstract
Introduction
Patients with nocturnal oximetry shows SpO2 during sleep of ≤ 90% in children for ≥ 5 minutes and sleep related hypoventilation is not documented could be diagnosed as sleep related hypoxemia (ICSD-3). However, known physiological causes should be indicated.
Report of Case
A 5-year-old Chinese boy was referred to sleep lab for daytime sleepiness for three months. Type I narcolepsy was confirmed.
Nocturnal PSG indicated a continuous low SpO2 baseline around 82%, with a nocturnal mean SpO2 of 83%, but no respiratory events. Voluntary hyperventilation made SpO2 increase from 83% to 95%, and hypoventilation syndrome was considered. PtcCO2 during PSG maintained 40mmHg, and no sleep related elevation observed. BPAP treatment had no effect on both SpO2. No dyspnea was complained. When he was 12 years old, follow-up PSG and MSLT indicated narcolepsy remained. During the past 7 years, no comorbidities occurred. Hb 104 g/L, RBC 3.53 × 1012/L, Hct 31%. ABG showed SaO2 of 97%, PaO2 98mmHg and PaCO2 40mmHg. Inconsistency between SpO2 and SaO2 reminds the existence of abnormal hemoglobin.
A positive isopropanol precipitation test and further hemoglobin electrophoresis showed abnormal Hb and HbA were 37.6% (normal 0%) and 58.4% (normal 94.3–98.5%), respectively, but HPLC did not identify. Spectrophotometric analysis indicated that the absorption spectra were significantly different at 450nm~540nm and 600nm~1000nm. Hemoglobin structure analysis found the abnormal site. Gene sequencing identified a novel HBB: c.212 C>A mutation, resulting in amino acid 71 to change from alanine(Ala) to aspartic(Asp) acid as a de novo mutation. A diagnosis of Hemoglobin Seattle [β71:Ala→Asp;HBB:c.212C>A] was confirmed.
Conclusion
Pediatric sleep medicine has a rapid development. Before a diagnosis of sleep related hypoxemia is made, in rare situation, abnormal hemoglobin should be considered.

Abstract
Abstract
Introduction
Catathrenia/nocturnal groaning, is a rare sleep disorder characterized by repeated groaning in a protracted expiration preceded by a deep inspiration. The classification was moved from ICSD-2 as parasomnia to sleep-disordered breathing(SDB) in ICSD-3. The pathogenesis of catathrenia is unknown.
Methods
To investigate catathrenia’s response to continuous positive airway pressure (CPAP) treatment, and its relationship with SDB. We analyzed patients diagnosed at the Sleep Center of Peking University People’s Hospital from 2009 to 2016. All patients were confirmed with nocturnal groaning by polysomnography(PSG), and recording of the sounds. The patients were recommended for treatment of CPAP.
Results
A total of 49 patients were recruited into this study, including 31 female and 18 male, age ranging from 16 to 64 years. The average onset age was 19.81 ± 8.65 years old, the average BMI was 21.76 ± 2.62 kg/m², the average groaning index (GI) was 11.58 ± 13.32 times per hour, and the average apnea hypopnea index (AHI) was 3.59 ± 8.83 times per hour. The GI in REM and NREM sleep were 39.31 ± 44.39 and 6.74 ± 8.5 times per hour respectively (p <0.01). The GI of 26 patients who received CPAP treatment decreased from 10.57 ± 12.01 to 5.65 ± 7.10 times per hour (p <0.001).
Conclusion
Catathrenia occurs mainly in REM sleep, and treatment with CPAP is effective, although cannot be completely eliminated. Suggest that catathrenia might be a sleep breathing disorder

Abstract
Abstract
Introduction
To evaluate the utility of the ring pulse oximeter for screening of OSA in adults.
Methods
87 adults were monitored by a ring pulse oximeter and PSG simultaneously during a nocturnal in-lab sleep testing. 3% oxygen desaturation index (ODI3); Mean oxygen saturation(MSpO2), Saturation impair time below 90% (SIT90) derived from an automated algorithm of the ring pulse oximeter. Meanwhile, the parameters of PSG were scored manually according to the AASM Manual. Correlation and receiver operator characteristic curve analysis were used to measure the accuracy of ring pulse oximeter and its diagnostic value for moderate to severe OSA (AHI≥15).
Results
Among the 87 participants, 18 cases were AHI<5, 17 cases were diagnosed with mild OSA (AHI:5-14.9), 25 cases were diagnosed with moderate OSA (AHI:15-29.9) and 27 cases were diagnosed with severe OSA (AHI≥30). There was no significant difference between PSG and ring pulse oximeter in regard to ODI3 (23.4±23.5 vs 24.7 ± 21.7), and SIT90 (1.54%, range 0.14%-8.99% vs. 3.20%, range 0.60%, 12.30%) (P>0.05], Further analysis indicated that two parameters from the oximeter correlated well with that derived from PSG (r=0.889, 0.567, respectively, both p<0.05). Although MSpO2 correlated significantly (r=0.448, P<0.05), the difference was remarkable [95.9%, range 94.0% to 97.0% vs. 94.5%, range 93.3% to 95.7%, p<0.05]. Bland-Altman plots showed that the agreement of these three parameters was within the clinical acceptance range. The ROC curve showed that the sensitivity and specificity of the ring pulse oximeter when the oximeter derived ODI3 ≥12.5 in the diagnosis of moderate to severe OSA were 82.7% and 74.3%, respectively.
Conclusion
The pilot study indicated that ring pulse oximeter can detect oxygen desaturation events accurately, therefore to be used as a screening tool for moderate to severe OSA.

Abstract
Introduction
To evaluate resting state functional connectivity and topological properties of brain network in narcolepsy compared with healthy controls.
Methods
Resting state fMRI was performed in 26 adult narcolepsy patients and 30 matched healthy controls. MRI data was first analyzed by group independent component analysis, then a graph theoretical method was applied to evaluate topological properties within whole brain. Small-world network parameters and nodal topological properties were measured. Altered topological properties in brain areas between groups were selected as ROI-seeds, then functional connectivity among these ROI-seeds were compared between groups. Partial correlation analysis was performed to evaluate the relationship between sleepiness severity and functional connectivity or topological properties in the narcolepsy.
Results
21 independent components out of 48 components were obtained. Compared with healthy controls, narcolepsy exhibited a significant decreased functional connectivity within the executive and salience network, while increased functional connectivity in bilateral frontal lobe within executive network can be detected in narcolepsy. There were no differences in small-world network properties between narcolepsy and healthy controls. The altered brain areas in nodal topological properties were mainly located in inferior frontal cortex, basal ganglia, anterior cingulate, sensory cortex, supplementary motor cortex and visual cortex between groups. In the partial correlation analysis, nodal topological properties in putamen, anterior cingulate and sensory cortex as well as functional connectivity between these brain regions were correlated with the severity of sleepiness (sleep latency, REM sleep latency and ESS) among narcolepsy.
Conclusion
Altered connectivity within executive network and salience network were found in narcolepsy. Functional connection changes between left frontal cortex and left caudate nucleus may be one of the parameters describing the severity of narcolepsy. Nodal topological properties alterations in left putamen and left posterior cingulate, changes in functional connectivity between left supplementary motor area and right occipital as well as changes in functional connectivity between left anterior cingulate gyrus and bilateral postcentral gyrus can be considered to be a specific indicator for evaluating the severity of narcolepsy.

Abstract
Introduction
Narcolepsy type 1 (NT1) is considered to be an autoimmune disease, and streptococcal infection may be an environmental trigger. However, previous studies from Asian narcolepsy patients did not reveal elevated anti-streptolysin O [ASO]. The aim is to investigate whether large sample Chinese patients with NT1 have an increase in antistreptococcal antibody titers.
Methods
A total of 214 narcolepsy patients and 360 healthy controls were recruited. All patients were DQB1*0602 positive with clear-cut cataplexy or had low CSF hypocretin-1. Participants were tested for ASO and anti DNAse B [ADB]. These patients were divided into five groups according to disease duration, including 29 patients less than 3 months; 25 from 3 months to 1 year; 40 from 1 to 3 years; 61 from 3 to 10 years and 59 patients over 10 years. Comparison was also made between children and adults with age matched controls, respectively.
Results
There were no significant differences between patients and healthy controls in regard to both ASO ≥ 200 IU (19.2% vs. 16.9%, p = 0.50) and ADB≥480IU (9.8% vs. 10.3%, p = 0.86). For children narcolepsy patients, ASO positive rates(19.8% vs. 18%, p = 0.68) and ADB positive rates(10.4% vs. 12%, p = 0.72) had no differences compared to age matched controls. And no difference was observed in adult narcolepsy patients either, with ASO positive rates (18.5% vs. 13.8%, p = 0.39) and ADB positive rates (9.3% vs. 5.3%, p = 0.42) compared to age matched controls, respectively. ASO (ADB) positive rates had no significant differences among different disease duration groups(p= 0.55, 0.9).
Conclusion
It is indicated that positive rates of ASO and ADB were not significantly different between Chinese patients with NT1 and healthy controls, including recent onset cases and children.

Abstract
Objective: To evaluate the clinical effects of anterolateral thigh free flap with fascia lata in the repair of dura mater defect after resection of head squamous cell carcinoma. Methods: From June 2016 to June 2018, Xijing Hospital of Air Force Medical University applied the free transplantation of anterolateral thigh flap with fascia lata to repair the dura mater defect of 12 patients with head squamous cell carcinoma, including 9 males and 3 females, aged from 35 to 74 years. The size of scalp soft tissue defects in patients after carcinoma resection ranged from 12 cm×10 cm to 24 cm×21 cm, and the size of dura mater defect of patients ranged from 7 cm×6 cm to 16 cm×14 cm. The size of flap of patients ranged from 14 cm×12 cm to 27 cm×24 cm, and the size of fascia lata ranged from 8 cm×7 cm to 17 cm×15 cm. The superficial temporal artery and middle temporal vein were connected by end to end anastomosis with the first musculocutaneous perforating branch of the descending branch of lateral femoral artery and its accompanying vein. The flap donor area was transplanted with autologous split-thickness skin graft from trunk and fixed with packing. Postoperative survival of flaps and skin grafts was observed. The patients were followed up regularly. The cranial magnetic resonance imaging was performed to observe the recurrence of intracranial tumors and dural integrity, shape of the flap and whether the donor site region was left with significant dysfunction were observed. Results: All the flaps and skin grafts survived well in 12 patients after surgery. Ten patients had primary healing at the edge of the flap suture; 2 patients had local sinus tract formation at the suture site of flap, with a small amount of cerebrospinal fluid leakage, and were recovered after outpatient dressing change. The patients were followed up for 10 to 36 months, and 3 patients with tumors involving in the dura mater sagittal sinus region had postoperative intracranial tumor recurrence. The tumor was resected again. All the patients had good dural integrity. The flaps of all patients were in good shape, and no obvious dysfunction remained in the flap donor site. Conclusions: Free transplantation of anterolateral thigh flap with fascia lata is an effective and reliable method to repair the dura mater defect following head squamous cell carcinoma resection. It can repair the scalp and dura mater defects caused by the invasion of squamous cell carcinoma and provide possibilities for skull reconstruction.

Abstract
Objective: To investigate the effect of Silent information regulator 1 (Sirt1) on the expression profile of long non-coding RNA (lncRNA) in macrophages upon lipopolysaccharide (LPS) treatment. Methods: Peritoneal macrophages (PM) were isolated from nine wild-type C57BL/6 male mice (wild-type group) and nine myeloid-specific Sirt1 knock-out mice (knock-out group). RNA samples were extracted from macrophages stimulated with 1 μg/ml LPS. Sequencing and the differentially expressed lncRNA were screened after the RNA was quantified. The threshold set for up-and down-regulated genes was a fold change (wild-type group/knock-out group) ≥2 and P≤0.05. Afterwards, gene ontology (GO) and pathway enrichment analysis were conducted and co-expression network map was constructed. Results: Four hundred and forty five lncRNA genes were differentially expressed (185 lncRNA genes were up-regulated and 260 lncRNA genes were down-regulated). Two hundred mRNA genes were differentially expressed (113 mRNA genes were up-regulated and 87 mRNA genes were down-regulated). It was found that the differentially expressed lncRNA genes and the predicted corresponding target genes were mainly distributed in the regions of biological processes of macrophage inflammatory response, macrophage chemotaxis and cell metabolism by GO and pathway enrichment analysis. Conclusion: lncRNA expression profile changes significantly in LPS induced macrophages isolated from Sirt1 knock out mice, which is closely related to the function of macrophages.

Abstract
OBJECTIVE The aim of this study was to investigate the roles of MT1JP and β-catenin in retinoblastoma. PATIENTS AND METHODS We performed quantitative Reverse Transcriptase-Polymerase Chain Reaction (qRT-PCR) to quantify the expressions of MT1JP and β-catenin in 44 retinoblastoma tissues and matched non-tumor tissues. What's more, retinoblastoma cell lines were transfected with pcDNA3.1-MT1JP, after which proliferation, cell cycle, apoptosis, and expression of β-catenin as well as its downstream targets were assayed. We also conducted TOP-Flash reporter assay to explore the activity of Wnt/β-catenin signaling pathway. RESULTS The results revealed that MT1JP was down-regulated, while β-catenin was highly expressed in retinoblastoma cells. Meanwhile, the forced expression of MT1JP impaired the expression of the β-catenin protein and its downstream targets such as cyclin D1, c-myc. CONCLUSIONS We demonstrated that MT1JP was a tumor suppressor by negatively modulating the activity of the Wnt/β-catenin signaling pathway in the development of retinoblastoma and might function as a prognostic biomarker and therapeutic target.

Abstract
This is a review regarding different types of cancer treatments. We aimed at analyzing the tumor microenvironment and the recent trends for the therapeutic applications and effectiveness for several kinds of cancers. Traditionally the cancer treatment was based on the neoplastic cells. Methods such as surgery, radiation, chemotherapy, and immunotherapy, which were targeted on the highly proliferating mutated tumor cells, have been investigated. The tumor microenvironment describes the non-cancerous cells in the tumor and has enabled to investigate the behavior and response of the cancer cells to a treatment process; it consists in a tissue that may have a predictive significance for tumor behavior and response to therapy. These include fibroblasts, immune cells and cells that comprise the blood vessels. It also includes the proteins produced by all of the cells present in the tumor that support the growth of the cancer cells. By monitoring changes in the tumor microenvironment using its molecular and cellular profiles as the tumor progresses will be vital for identifying cell or protein targets for the cancer prevention and its therapeutic purposes.

Abstract
Objective: To evaluate the utility of a portable monitor at home for diagnosis of obstructive sleep apnea (OSA) in Chinese adults. Methods: Eighty nine patients suspected of OSA underwent overnight, unattended home sleep apnea testing (HSAT) with a portable monitor (Nox-T3, Nox Medical Inc. Iceland)followed by an in-laboratory polysomnogram (PSG) with simultaneous portable monitor (PM) recording within one week. PSG and PM recorder were scored according to recommended guidelines by independent technicians. The correlation between PSG apnea hypopnea index (AHI) and PM respiratory disturbance index (RDI) were evaluated. Results: Sleep testing showed RDI was (30.0±20.9) events/h on HSAT, and (33.4±22.4) events/h on in-laboratory PM recording. Apnea-hypopnea index (AHI) on PSG was (35.1±23.7) events/h. There was significantly statistical difference among the three group (P<0.001). Both RDI on HSAT and RDI on in-laboratory PM correlated significantly with AHI on PSG (r=0.877, P<0.001 and r=0.962, P<0.001, respectively). Bland-Altman analysis of AHI on PSG versus RDI on HSAT showed a mean difference of 4.4 events/h; limits of agreement was -17.6 to 26.5 events/h. Closer agreements were present when comparing the simultaneous recordings, with AHI on PSG versus RDI on in-laboratory PM showing a mean difference of 1.4 events/h, and limits of agreement was -11.3 to 14.2 events/h. Based on a threshold of AHI≥5 events/h, RDI on HSAT had 98.8% sensitivity, 40.0% specificity. Using an AHI ≥ 15 events/h, RDI on HSAT had 91.5% sensitivity, 76.5% specificity. Conclusion: Type 3 PM has a good diagnostic value for adult OSA patients and there is close agreement between the Type 3 portable monitor and PSG.

Abstract
Objective: To study the clinical subtypes of obstructive sleep apnea hypopnea syndrome (OSAHS) by cluster analysis, and to discuss the characteristics and clinical significance of these subtypes. Methods: A retrospective analysis was done among patients who were diagnosed with OSAHS in the Sleeping Center of the Second Affiliated Hospital of Soochow University from January 2010 to June 2018. In this cluster analysis, 16 main symptoms, 7 comorbidities and 3 assessment scales were included. After selecting the best model, the parameters and characteristics of different subtypes were compared and analyzed. Results: A total of 2 592 patients with complete data were included in this study. After cluster analysis, they were divided into 4 groups: sleep apnea group (1 173 cases, 45.3%), daytime sleepiness group (518 cases, 20.0%), insomnia and memory loss group (212 cases, 8.2%), mild symptom group (689 cases, 26.6%). In the sleep apnea group, the patients were found to be younger [(40.2±10.4) years old], with higher body mass index (BMI) [(27.7±3.7) kg/m(2)] when compared to the other groups. In addition, the prevalence of comorbidities of this group was found to be lower, whereas the probability of sleep apnea symptom was the highest (94.7%). In daytime sleepiness group, the Epworth Sleepiness Scale (ESS) score was the highest [(12.4±5.5) points], and the probability of daytime sleepiness symptom was also found to be the highest (88.0%). The age of patients in the insomnia and memory loss group was the highest [(51.1±13.0) points], with the highest percentage of women (19.3%). The probability of insomnia was found to be 70.3%, and memory loss symptoms was 88.2% which were the highest when compared to the other groups. The prevalence of comorbidities was the highest, and the scores of short mental state scale (MMSE) and Montreal cognitive assessment (MoCA) were the lowest with a mean of [(28.5±2.4) points] and [(25.4±3.2) points], respectively, among the 4 groups. The probability of most symptoms and comorbidities were found be the lowest in the mild symptom group. There were significant differences in the main symptoms among the 4 groups (P<0.05). Symptoms like sleep apnea, daytime sleepiness, insomnia, memory loss, headache and dry mouth upon awakening were found significantly different in pairwise comparisons among the groups (P<0.002). Conclusion: The patients with OSAHS can be divided into four clinical subtypes by cluster analysis, each of which is significantly heterogeneous, and this is helpful to evaluate the condition and guide individualized treatment.
