Abstract
Objective:To remove the immune function of children with obstructive sleep apnea hypopnea syndrome by resection of adenoids and tonsillar. Method: The fasting peripheral venous blood of children with OSAHS and healthy children were collected. The lymphocyte subsets, NK cells and immunoglobulin levels were compared between the two groups. The fasting blood samples of OSAHS children were collected again after 2d, 30d, 60d and 90d after operation. The changes of lymphocyte subsets, NK cells and immunoglobulin levels were observed after operation. Result: Before operation, at the 0.05 test level, it was not yet clear that the levels of IgG, IgM, IgA, NK, CD3+, CD4+ and CD8+ in OSAHS children were significantly different from those in the control group. The levels of IgA, CD3+ and CD4+ decreased significantly in children at 2d and OSAHS after operation, and IgG, IgM, IgA, NK, CD3+ and IgA continued to rise after 60d until ninetieth day after operation. Conclusion: There is no statistical disorder of immune level in children with OSAHS compared with healthy children. The implementation of adenoidectomy and tonsillectomy in children with OSAHS, the level of immunity in 90 days can be restored to the preoperative level.

Abstract
OBJECTIVE To summarize the experience of flexible ureteroscopic holmium laser resection in treatment of renal pelvic carcinoma and to evaluate its value in treatment of renal pelvic carcinoma. METHODS The clinical data of 6 patients with renal pelvic carcinoma treated in Peking University Third Hospital from January 2015 to January 2017 were retrospectively analyzed. The 6 patients were treated by the same experienced urologist and by flexible ureteroscopic holmium laser resection of renal pelvic tumors under general anesthesia. Regarding the intensity of the holmium laser, 10-30 W was generally used with settings of 0.5-1.5 J and 10-20 Hz. In general, a 200 μm end-firing holmium laser fiber was used. Narrow-band imaging (NBI) technique was applicated to search for tumors and check whether the excision was satisfactory. Routine "second flexible ureteroscopy" was performed after 4-6 weeks, and suspected lesions were referred for a biopy, then vaporized and cauterized. The ureteroscopy was examined every 6 months after operation, and color Doppler ultrasound, computed tomography urography (CTU) or magnetic resonance urography (MRU) were performed at the same time. The urine tumor cells were examined for 3 days before the operation, and the urine tumor markers, such as urinary nuclear matrix protein 22 (NMP22) were tested. For cases with highisk urothelial carcinoma and normal renal function, and 6 cycles of systemic adjuvant chemotherapy were performed after operation. RESULTS All of the cases were successfully treated. The data were as follows: the operation time 77.5 min (45-115 min), the blood loss 10 mL (5-20 mL), and hospital stay after surgery 3 days (2-5 days). After 13-34 months' followp, two patients had recurrent tumor recurrence and underwent resection operation. Two patients received systemic adjuvant chemotherapy after operation. Case 5 was histopathologically high grade urothelial carcinoma, and 6 cycles of systemic chemotherapy were given after operation. Local recurrence occurred during chemotherapy, and then endoscopic operation was performed, and no recurrence occurred in the follow-up for 12 months after reoperation. In case 6, the pathology was low grade urothelial carcinoma, but the case was multiple tumors in the right renal calyx and the lower calyx. Then 6 cycles of systemic chemotherapy were given, and no recurrence was found in the followp for 13 months. CONCLUSION Transurethral flexible ureteroscopic holmium laser resection is relatively safe for the treatment of renal pelvic carcinoma. It is suitable for special cases of solitary kidney and renal dysfunction, as well as for patients with low risk urinary tract epithelial tumors, but the recurrence rate is high, and the indications need to be strictly controlled. Patients with high-risk urothelial carcinoma who underwent endoscopic resection are advised to receive systemic adjuvant gemcitabine and cisplatin (GC) regimen after surgery, in order to increase the overall survival rate. Systemic chemotherapy combined with endoscopic operation may become a new treatment for upper tract urothelial carcinoma (UTUC).

Abstract
A key requirement in the field of ultrafast vibrational spectroscopy is to efficiently generate intense tunable narrowband picosecond laser pulses synchronized to a broadband femtosecond laser source. Current nonlinear methods for picosecond pulse generation suffer from complexities in both experimental implementation and pulse frequency tunability. We present here a straightforward method for spectral bandwidth compression that produces frequency tunable picosecond pulses with efficient power conversion. Broadband femtosecond laser pulses are compressed to narrowband picosecond pulses using frequency domain sum-frequency generation of spatially chirped pulses, achieving spectral bandwidths of <20 cm-1 and power conversion efficiency of ∼18%. The experimental design of the bandwidth compressor is presented and its application to stimulated Raman spectroscopy is demonstrated.

Abstract
Blood-circulating microRNAs (miRNAs) have been reported to be used as potential biomarkers in various cancers. MiR-101 has been found to act as a tumor suppressor in many tumor types, but little is known for osteosarcoma. The purpose of this study was to investigate miR-101 expression in osteosarcoma patients and assess its correlation with clinical features and prognosis. Serum samples from 152 osteosarcoma patients and 70 healthy controls were detected using quantitative reverse-transcription polymerase chain reaction (qRT-PCR). The data showed that miR-101 expression levels were remarkably underexpressed in serum samples from osteosarcoma patients compared to controls, and the post-treatment serum miR-101 expression was significantly higher than that in the pre-treatment expression. Low serum miR-101 expression was positively associated with advanced clinical stage and distant metastasis. Receiver operating characteristic (ROC) curve analysis showed that serum miR-101 could serve as a useful marker for osteosarcoma diagnosis, with a high sensitivity and specificity. Moreover, patients with high miR-101 expression had longer overall survival and recurrence free survival than those with low miR-101 expression. In addition, both univariate and multivariate analyses showed that serum miR-101 downregulation was associated with shorter overall survival and recurrence free survival. Our present results implicated serum miR-101 might be a useful biomarker for the clinical diagnosis and prognosis of osteosarcoma.

Abstract
OBJECTIVE To investigate the efficacy of transesophageal echocardiography (TEE) in the treatment of nonvalvular atrial fibrillation with left atrial appendage (LAA) occlusion. PATIENTS AND METHODS Forty-nine patients with nonvalvular atrial fibrillation were selected from January 2015 to December 2015 to serve as control group, and 49 patients with nonvalvular atrial fibrillation were selected from January 2016 to December 2016 to serve as observation group. Patients in both groups were treated with LAA occlusion. After surgery, patients in control group received 2D-transesophageal echocardiography (2D-TEE), while patients in observation group received 3D-TEE. LAA diameter, maximum depth, postoperative parameters, and postoperative complications were compared between two groups. RESULTS The maximum LAA diameter can be measured from different angles in control group, and maximum depth cannot be measured in control group. No significant differences in maximum LAA diameter and maximum depth were found between two groups from different angles (p<0.05). No significant difference in left ventricular end diastolic diameter (LVEDd), left atrial diameter (LA-d), left ventricular ejection fraction (LVEF), mitral regurgitation volume (MV Reg V), E peak and pulmonary vein diastolic flow velocity (PVd) were found between those two groups (p<0.05). The overall occurrence of postoperative complications in observation group and control group were 0.00% and 12.24%, respectively, significant difference was found between those two groups (p<0.05). CONCLUSIONS Compared with 2D-TEE, the application of 3D-TEE in treatment of nonvalvular atrial fibrillation with left atrial appendage occlusion is more conducive to the selection of the size of the reservoir, and can reduce the occurrence of postoperative complications.

Abstract
OBJECTIVE Predictive factors associated with clinical outcomes of chronic norovirus infection (CNI) in primary immunodeficiency diseases (PIDD) are lacking. METHOD We sought to characterize CNI using a multi-institutional cohort of patients with PIDD and CNI using the Clinical Immunology Society's CIS-PIDD Listserv e-mail group. RESULTS Thirty-four subjects (21 males and 13 females) were reported from centers across North America, Europe, and Asia. All subjects were receiving high doses (median IgG dose: 1200 mg/kg/month) of supplemental immunoglobulin therapy. Fifty-three percent had a complete absence of B cells (median B-cell count 0; range 0-139 cells/μL). Common Variable Immune Deficiency (CVID) subjects manifested a unique phenotype with B-cell lymphopenia, non O+ blood type, and villous atrophy (logistic regression model, P = 0.01). Five subjects died, all of whom had no evidence of villous atrophy. CONCLUSION While Norovirus (NoV) is thought to replicate in B cells, in this PIDD cohort of CNI, B-cell lymphopenia was common, indicating that the presence of B lymphocytes is not essential for CNI.

Abstract
X-ray flash radiography is an effective diagnostic in implosive research. While scattering reduces the contrast of radiography, the anti-scattering grids can effectively intercept the scattered radiation and acquire better images. A focused sub-megavolt grid is elaborately manufactured with the combination of lithography, etching, and laser drilling. The consistency of Monte Carlo simulations and radiographic experiments suggests a transmission of about 36% and a 1000 times improvement for the signal to scatter ratio of the grid.

Abstract
OBJECTIVE To investigate the role of microRNAs (miRNAs) and its mechanism in osteoblast mineralization. MATERIALS AND METHODS Real-time polymerase chain reaction (PCR), Northern Blot, and Western Blot were used to identify the expression mode of regulators. Overexpression and down-regulation experiments were carried out to study the role of miR-98 and interactions between regulators. Bioinformatics calculation and luciferase reporter assay were used to prove the target gene. Electrophoretic mobility shift assay (EMSA), chromatin immunoprecipitation (CHIP), and promoter luciferase reporter assay confirmed the relationship between the regulator and the promoter of miR-98. RESULTS MiR-98 was up-regulated during osteoblast mineralization. Overexpression of miR-98 promoted osteoblast mineralization. Factor inhibiting activating transcription factor 4 (ATF4)-mediated transcription (FIAT), a negative regulator of osteoblast differentiation, was confirmed to be a target of miR-98. As a motivator in osteoblast mineralization, Sp7 transcription factor 7 (Sp7) promoted miR-98 transcription by a combination on the promoter region. CONCLUSIONS Our study showed that miR-98 was an important regulator in osteoblast mineralization and miR-98 carried out its function through a novel miR-98-FIAT/Sp7 regulatory loop. It provides new insights into the roles of miRNAs in osteoblast mineralization.

Abstract
We present two approaches to enhance the photoluminescence quantum yield (PLQY) of surface-anchored metal-organic frameworks (SURMOFs). In the first approach we fabricate SURMOFs from a mix of an emissive linker with an optically-inert linker of equivalent length, diluting the emissive linker while maintaining the SURMOF structure. This approach enhances the internal PLQY. However, the increase in internal PLQY is achieved at the expense of a drastic reduction in optical absorption, thus the external PLQY remains low. To overcome this limitation, a second approach is explored wherein energy-accepting guest chromophores are infiltrated into the framework of the active linker. At the correct acceptor concentration, an internal PLQY of 52% - three times higher than the previous approach - is achieved. Additionally, the absorption remains strong leading to an external PLQY of 8%, an order of magnitude better than the previous approach. Using this strategy, we demonstrate that SURMOFs can achieve PLQYs similar to their precursor chromophores in solution. This is of relevance to SURMOFs as emitter layers in general, and we examine the optimized emitter layer as part of a photon upconversion (UC) SURMOF heterostructure. Surprisingly, the same PLQY is not observed after triplet-triplet annihilation in the UC heterostructure as after its normal photoexcitation (although the UC layers exhibit low thresholds consistent with those reported in our previous work). We discuss the potential bottlenecks in energy transport that could lead to this unexpected reduction in PLQY after excitation via triplet-triplet annihilation, and how future design of SURMOF UC multilayers could overcome these limitations.

Abstract
In the current era, cardiovascular intensive care units care for more complex patients who are far sicker than historical post-myocardial infarction patients, and sedation has become a common intervention in these units. Current sedation best practices derive mainly from non-cardiac units which limits their generalization to the critically ill cardiac patient. Thus, a great variability in sedation protocols, especially the selection of sedative agents, is commonly seen in daily practice across cardiac units. We present an updated review on sedation in cardiovascular critical care medicine with emphasis on the hemodynamic impact. The goal of this review is to generate a general sedation algorithm specific for the cardiac patient.

Abstract
Tissue biopsy is the standard diagnostic procedure for cancer. Biopsy may also provide material for genotyping, which can assist in the diagnosis and selection of targeted therapies but may fall short in cases of inadequate sampling, particularly from highly heterogeneous tumors. Traditional tissue biopsy suffers greater limitations in its prognostic capability over the course of disease, most obviously as an invasive procedure with potential complications, but also with respect to probable tumor clonal evolution and metastasis over time from initial biopsy evaluation. Recent work highlights circulating tumor DNA (ctDNA) present in the blood as a supplemental, or perhaps an alternative, source of DNA to identify the clinically relevant cancer mutational landscape. Indeed, this noninvasive approach may facilitate repeated monitoring of disease progression and treatment response, serving as a means to guide targeted therapies based on detected actionable mutations in patients with advanced or metastatic solid tumors. Notably, ctDNA is heralding a revolution in the range of genomic profiling and molecular mechanisms to be utilized in the battle against cancer. This review will discuss the biology of ctDNA, current methods of detection and potential applications of this information in tumor diagnosis, treatment, and disease prognosis. Conventional classification of tumors to describe cancer stage follow the TNM notation system, heavily weighting local tumor extent (T), lymph node invasion (N), and detectable metastasis (M). With recent advancements in genomics and bioinformatics, it is conceivable that routine analysis of ctDNA from liquid biopsy (B) may make cancer diagnosis, treatment, and prognosis more accurate for individual patients. We put forward the futuristic concept of TNMB tumor classification, opening a new horizon for precision medicine with the hope of creating better outcomes for cancer patients.

Abstract
We investigated the crystal-electric field ground state of the 4f manifold in the strongly correlated topological insulator SmB_{6} using core-level nonresonant inelastic x-ray scattering. The directional dependence of the scattering function that arises from higher multipole transitions establishes unambiguously that the Γ_{8} quartet state of the Sm f^{5} J=5/2 configuration governs the ground-state symmetry and, hence, the topological properties of SmB_{6}. Our findings contradict the results of density functional calculations reported so far.

Abstract
Methylammonium (MA) and formamidinium (FA) are two typical A site cations in lead halide perovskites. Instability of synthesised crystals will degrade the properties of the photoelectrical device constructed by such perovskites. MAPbI3 and FAPbI3 in cubic crystal structure have been demonstrated to be the most stable at room temperature. Herein we synthesised MA(EA)PbI3 and FA(MA)PbI3 single crystals using an inverse-temperature crystallization strategy by partially substituting the methylammonium (MA) with ethylammonium (EA) and the formamidinium (FA) with methylammonium (MA) respectively. The XRD results show that both crystal structures are cubic, which means organic incorporation can stabilize the crystal structure of lead halide perovskites. The lattice distortion decrease and strain relaxation in single crystals were considered to be the reason leading to higher stability. The single crystals of MA(EA)PbI3 and FA(MA)PbI3 with low trap state density exhibit excellent light-absorbing properties, indicating their potential applications in photoelectric devices.

Abstract
OBJECTIVE To compare brain-derived neurotrophic factor (BDNF) levels between offspring of individuals with bipolar disorders (BD) and healthy controls (HCs) and investigate the effects of BDNF levels and body mass index (BMI) on brain structures. METHOD Sixty-seven bipolar offspring and 45 HCs were included (ages 8-28). Structural images were acquired using 3.0 Tesla magnetic resonance imaging. Serum BDNF levels were measured using enzyme-linked immunosorbent assay. Multivariate and univariate analyses of covariance were conducted. RESULTS Significantly higher BDNF levels were observed among bipolar offspring, relative to HCs (P > 0.025). Offspring status moderated the association between BDNF and BMI (F1 =4.636, P = 0.034). After adjustment for relevant covariates, there was a trend for a significant interaction of group and BDNF on neuroimaging parameters (Wilks'λ F56,94 =1.463, P = 0.052), with significant effects on cerebellar white matter and superior and middle frontal regions. Brain volume and BDNF were positively correlated among HCs and negatively correlated among bipolar offspring. Interactions between BDNF and BMI on brain volumes were non-significant among HCs (Wilks'λ F28,2 =2.229, P = 0.357), but significant among bipolar offspring (Wilks'λ F28,12 =2.899, P = 0.028). CONCLUSION Offspring status and BMI moderate the association between BDNF levels and brain structures among bipolar offspring, underscoring BDNF regulation and overweight/obesity as key moderators of BD pathogenesis.

Abstract
Dusky (dy) is required for cytoskeletal reorganization during wing morphogenesis in Drosophila melanogaster, but which genes participate together with dy for wing morphogenesis has remained unclear. In Tribolium castaneum, dy is highly expressed at the late embryonic stage. Tissue-specific expression analysis indicated high expression levels of dy in the epidermis, head and fat body of late-stage larvae. RNA interference (RNAi) targeting dy significantly decreased adult wing size and caused improper folding of the elytra. Meanwhile, dy knockdown reduced the transcription of four-jointed (fj) and forked (f). Our results show that fj RNAi reduces adult wing size and that silencing f results in abnormal wing folding in T. castaneum. Interestingly, knocking down fj and f simultaneously phenocopies dy RNAi, suggesting that dy probably acts upstream of fj and f to regulate wing morphogenesis in T. castaneum.

Abstract
Objective: To analyze satisfaction with follow-up management of HIV/AIDS cases conducted by Community Health Service Center (CHS) and related factors in Hongkou district, Shanghai. Methods: Out of 302 HIV/AIDS cases followed up by CHS in Hongkou district from 2012 to 2016, 263 HIV/AIDS cases were recruited to participate in a cross-sectional study assessed by self-designed questionnaire-based interview during October 1, 2016 and October 20, 2016, with efficiency of 87.1%. Information of basic characteristics including sociodemographic, routes of infection, CD4(+)T cell counts, diagnose of AIDS and status of receiving ART were collected, as well as satisfaction with follow-up management conducted by CHS including service professionalism, service attitude, service environment, referral service, privacy protection, health education, psychological support, and care and assistance. Factors related to satisfaction were analyzed using multiple binary logistic regression. Results: Among 263 HIV/AIDS cases, the average age was 42.0±13.5, 93.2% (245 cases) were male and the proportion of overall satisfaction was 72.2% (190 cases). Out of 8 items of satisfaction, service attitude and health education got the highest score with a total number of 235 (89.4%) answering "very satisfied" or "satisfied" , while care and assistance got the lowest score with a total number of 69 (26.2%) answering "dissatisfied" or "very dissatisfied" . Compared to HIV/AIDS local residents and followed up by CHS <12 months, those who were non-local residents and followed up by CHS ≥12 months were more likely to be satisfied, the OR (95%CI) were 2.66 (1.30-5.44) and 2.52 (1.01-6.29), respectively. Compared to HIV/AIDS ≤30 years old and receiving ART, those who were 31-50 years or >50 years old and not receiving ART were less likely to be satisfied, the OR (95%CI) were 0.36 (0.15-0.89), 0.32 (0.10-0.97) and 0.11 (0.01-0.90), respectively. Conclusion: Satisfaction with follow-up management conducted by CHS in Hongkou district is relatively high. Age, residence, status of receiving ART and cumulative time of following up by CHS are significantly associated with satisfaction, suggesting that CHS should improve their professional abilities during follow-up management, as well as be more targeted and focus on different aspects.
