Abstract
OBJECTIVE This article reports the first case of pregnancy after frozen-thawed ovarian tissue transplantation to prevent iatrogenic premature ovarian insufficiency in China. METHODS Ovarian tissue cryopreservation was performed in a patient with myelodysplastic syndrome (MDS) before multi-agent chemotherapy and hematopoietic stem cell transplantation. Two years later, she showed complete remission from MDS, and six frozen-thawed ovarian tissue strips were transplanted into the peritoneal pocket. RESULTS The patient's ovarian activity was restored 3 months after transplantation, and pregnancy occurred spontaneously 27 months after grafting. Until now, the pregnancy has progressed for 30 weeks, and the repeated ultrasound showed normal fetal development. CONCLUSION This is the first pregnancy resulting from ovarian tissue cryopreservation and transplantation in China.

Abstract
Ground-state structures of a two-dimensional (2D) system composed of superparamagnetic charged particles are investigated by means of molecular dynamics simulation. The charged particles trapped in a quadratic potential interact with each other via the repulsive, attractive, and magnetic dipole-dipole forces. Simulations are performed within two regimes: a one-component system and a two-component system where the charged particles have the identical charge-to-mass ratio. The effects of magnetic dipole-dipole interaction, mixing ratio of the two species and confinement frequency on the ground-state structures are discussed. It is found that as the strength of the magnetic dipole increases, the charged particles tend to self-organize into chainlike structures. The two species particles exhibit different structural features, depending on the competition of electrostatic repulsive interaction, magnetic dipole-dipole interaction and confinement force. The potential lanes are observed through analyzing the global potential of the magnetic particles, which guide the unmagnetic particles aligning themselves in the direction of the potential lanes.

Abstract
Objective: To investigate the protective role of alprostadil on aortic dissection. Methods: 26 C57BL6 male mice were divided into control group (normal drinking water, n=13) and model group (1 g·kg-1·d-1 BAPN via drinking water, n=13). On day 14, mRNA expression of inflammatory-related genes as well as EP receptor families were detected by RT-PCR (n=6 each) and EP4 protein levels were determined by Western blot (n=7 each). Another 88 mice were divided into 3 groups: control group (n=22), model group (n=33) and treatment group (n=33). The mice in model group and treatment group were applied with BAPN (1 g·kg-1·d-1) via drinking water. The mice in treatment group received additional intraperitoneal injection with alprostadil (80 μg·kg-1·d-1) for 28 days. The mice in the control and model group received equal volume intraperitoneal injection with 0.9% saline respectively. The body weight and systolic blood pressure, the mortality and morbidity were monitored from the beginning until the designed end of the study. On day 28, the mice were sacrificed and aorta were fixed, embedded and sliced, followed by staining with HE and Victoria Blue. The distribution of EP4 was determined by immunohistochemistry in control (n=6) and model group (n=6). Furthermore, the concentration of PGE1 were tested among model (n=3) and treatment group (n=4). EP4 protein expression was determined in model group (n=7) and treatment group (n=6). Results: On day 14, mRNA expression level of MCP-1 ((2.74±1.55) vs. (1.00±0.49),<0.05) and MMP2((1.38±0.42) vs. (1.00±0.27), P<0.05) was significantly upregulated in model group compared with control group. Protein expression of EP4 receptor also increased in aorta in model group compared with control group (1.48±0.51 vs. 1.00±0.19, P<0.05). In the dissection area, the EP4 expression was also enriched compared with non-dissection area, particularly in endothelial cells and inflammatory cells on day 28. BAPN applied in drinking water (model and treatment groups) successfully induced the aortic dissection in mice, some mice died of the rupture. The elastic fibers were fractured, and the infiltrated immune cells were visible in dissected tissue. False lumen was formed. There was no dissection and death in the control group. Compared with control group, the morbidity and mortality rates were significantly increased in the model group (60.6%, 20/33, 30.3%, 10/33) and the treatment group (72.7%, 24/33, 24.2%, 8/33). The mortality and morbidity rates were similar between model and treatment groups. There is no difference in terms of SBP among three groups (P>0.05). Further study showed that after alprostadil injection, the blood concentration of PGE1 was increased in treatment group ((0.540±0.041 vs. 0.436±0.012)μmol/L, P<0.05). Besides, the EP4 receptor expression was downregulated in the treatment group compared to model group (0.60±0.30 vs. 1.00±0.20, P<0.05). Conclusion: EP4 expression is upregulated in BAPN induced aortic dissection mouse model. No protective effects are observed post alprostadil treatment in this model probably due to the reduced expression of EP4.

Abstract
AIMS In the pivotal Trastuzumab for Gastric Cancer (ToGA) trial, trastuzumab improved median survival in patients with advanced HER-2-positive gastric and gastroesophageal cancer from 11.1 to 13.8 months; however, its effectiveness in routine clinical practice has not been evaluated. Our objective was to evaluate the uptake and outcomes of trastuzumab in a population-based cohort of patients with oesophageal, gastroesophageal and gastric cancer in Ontario, Canada. MATERIALS AND METHODS The Ontario Cancer Registry and linked treatment records were used to identify all patients with oesophageal, gastroesophageal and gastric cancer treated with trastuzumab during 2012-2017. Outcomes were analysed from the time of first trastuzumab cycle and included a primary outcome (survival) and secondary outcomes (uptake, delivery, 30-day hospital admission and 30-day mortality). Trends over the study period and survival were evaluated. RESULTS In total, 476 patients with oesophageal, gastroesophageal and gastric cancer received trastuzumab during the study period. The mean age was 62 years, 78% (370/476) were male, and 65% (312/476) had gastric cancer. The annual number of patients receiving trastuzumab increased over the study period (53 in 2012 and 101 in 2017). The median number of cycles of trastuzumab delivered was six. Thirty-day hospital admission and mortality rates were 17% and 4%, respectively. The median overall survival was 282 days (9.3 months). CONCLUSIONS The median survival of patients treated with trastuzumab for advanced oesophageal, gastroesophageal and gastric cancer in routine practice is substantially less than that observed in the pivotal clinical trial. Studies of comparative effectiveness using real-world data offer insight into outcomes achieved in routine practice.

Abstract
During the Marine Aerosol Cloud and Wildfire Study (MACAWS) in June and July of 2018, aerosol composition and cloud condensation nuclei (CCN) properties were measured over the N.E. Pacific to characterize the influence of aerosol hygroscopicity on predictions of ambient CCN and stratocumulus cloud droplet number concentrations (CDNC). Three vertical regions were characterized, corresponding to the marine boundary layer (MBL), an above-cloud organic aerosol layer (AC-OAL), and the free troposphere (FT) above the AC-OAL. The aerosol hygroscopicity parameter (κ) was calculated from CCN measurements (κ CCN) and bulk aerosol mass spectrometer (AMS) measurements (κ AMS). Within the MBL, measured hygroscopicities varied between values typical of both continental environments (~0.2) and remote marine locations (~0.7). For most flights, CCN closure was achieved within 20% in the MBL. For five of the seven flights, assuming a constant aerosol size distribution produced similar or better CCN closure than assuming a constant "marine" hygroscopicity (κ = 0.72). An aerosol-cloud parcel model was used to characterize the sensitivity of predicted stratocumulus CDNC to aerosol hygroscopicity, size distribution properties, and updraft velocity. Average CDNC sensitivity to accumulation mode aerosol hygroscopicity is 39% as large as the sensitivity to the geometric median diameter in this environment. Simulations suggest CDNC sensitivity to hygroscopicity is largest in marine stratocumulus with low updraft velocities (<0.2 m s-1), where accumulation mode particles are most relevant to CDNC, and in marine stratocumulus or cumulus with large updraft velocities (>0.6 m s-1), where hygroscopic properties of the Aitken mode dominate hygroscopicity sensitivity.

Abstract
A facile and sensitive self-powered cathodic photoelectrochemical (PEC) aptasensor is reported for the detection of prostate-specific antigen (PSA) based on CuO-Cu2O nanowire array grown on Cu mesh (CuO-Cu2O NWA/CM) as electrode. The mixed narrow band gaps of the CuO-Cu2O heterostructure ensured its wide absorption band, effective electron/hole separation, and high photocatalytic activity in the visible region. In addition, nanowires directly grown on the substrate provided high specific surface area and exposed abundant active sites, thus guaranteeing its high photocatalytic efficiency. Therefore, the self-powered sensor exhibited favorable analytical performance with fast response, wide linear ranges of 0.01 to 5 ng/mL and 5 to 100 ng/mL, an acceptable detection limit of 3 pg/mL, and reasonable selectivity and stability. The proposed CuO-Cu2O NWA/CM can be considered a promising visible light-responsive photoactive material for fabrication of PEC aptasensor with high performance.

Abstract
Objective: To confirm the cutoff induration diameter of tuberculin skin test (TST) so as to decrease the false positive of the TST. Methods: Fasting blood glucose test, TST and Quanti FERON-TB (QFT) Gold In-Tube test were administered to recruit participants at the baseline stage. QFT was used as the gold standard to determine the cutoff of the TST test. Results: Overall, 5 405 participants were enrolled in this study, of whom 1 104 (20.4%) were QFT positive. Among all the 5 405 participants that without stratification, diagnostic value reached the highest when the induration diameter was 10.25 mm with sensitivity and specificity as 0.731 and 0.727, respectively. When the participants were divided into groups as nondiabetics, confirmed diabetics, undiagnosed diabetics, the sensitivities and specificities appeared as 0.701, 0.837, 0.824 and 0.805, 0.821, 0.778 with induration diameters as 11.25 mm, 10.25 mm and 11.25 mm, respectively. Conclusions: Findings of this study confirmed that the specificity of tuberculin test could be significantly improved by using 10-12 mm as the cutoff value for diagnosing the latent tuberculosis infection.

Abstract
An ultrasensitive photoelectrochemical (PEC) biosensor was constructed based on gold nanoparticles (Au NPs)/tungsten sulfide nanorod array (WS2 NA) photoelectrode as the PEC matrix and silver nanoparticles/flake-like zinc metal-organic framework (Ag/ZnMOF) nanozyme with the peroxidase mimetic enzyme property for sensitive detection of bleomycin (BLM). In particular, Au/WS2 and Ag/ZnMOF were linked by thiolate DNA1 and DNA2 strand, respectively, and the Au/WS2-Ag/ZnMOF probe was prepared via hybridization reaction between the two DNAs. The introduction of Ag/ZnMOF in the probe offers two functions: i) the steric hindrance effect can effectively impede electron transport and reduce the photocurrent; ii) Ag/ZnMOF nanozyme can also be used as mimic peroxidase to effectively catalyze 3,3-diaminobenzidine (DAB) to produce the relevant precipitation, which will further reduce photocurrent and eliminate false positive signals. When BLM exists, BLM with Fe2+ as irreversible cofactor can specifically recognize and cleave of the 5'-GC-3' active site of DNA2, resulting in reduced precipitation deposited on the electrode and recovery of PEC signal. The highly sensitive PEC biosensor exhibits a the linear strategy from 0.5 nM to 500 nM with a detection limit down to 0.18 nM. Further, the unique strategy was conducted in biological samples for BLM detection with satisfactory consequence, offering available and efficient pathway for disease diagnosis.

Abstract
OBJECTIVE MiR-381-3p plays an essential role in the progression of a variety of cancers, but its expression and role in papillary thyroid carcinoma (PTC) progression have not been investigated. The aim of this study was to investigate the expression of miR-381-3p and its function in PTC. PATIENTS AND METHODS The expression levels of miR-381-3p and low-density lipoprotein receptor‑related protein 6 (LRP6) mRNA in PTC tissues and cell lines were measured using RT-PCR. Cell proliferation, migration and invasion were assessed by cell viability assay and transwell assay. Luciferase assays and Western blotting were performed to demonstrate miR-381-3p target gene. RESULTS We found that miR-381-3p was significantly down-regulated in PTC tissues and cell lines. In vitro assay indicated that up-regulation of miR-381-3p significantly suppressed PTC cell proliferation, migration and invasion. Moreover, luciferase reporter gene assay demonstrated that miR-381-3p could target LRP6 by binding to the 3' UTR. Western blot and Reverse transcription‑quantitative polymerase chain reaction (RT‑qPCR) showed that miR-381-3p overexpression suppressed the expression of LRP6 at both mRNA and proteins levels. In addition, functional experiment confirmed that LRP6 was involved in the suppressive effect of miR-381-3p-mediated PTC on cell proliferation, migration and invasion. CONCLUSIONS Our findings suggested, for the first time, that miR-381-3p was lowly expressed in PTC tissues, and its up-regulation inhibited tumorigenesis of PTC by targeting LRP6.

Abstract
Objective: To investigate the therapeutic effects of surgical management for local retroperitoneal recurrence of renal cell carcinoma after radical nephrectomy. Methods: Clinical and follow-up data of 33 cases of local recurrence after radical nephrectomy in Renji Hospital from January 2010 to April 2018 were retrospectively analyzed. Results: In these 33 patients, 25 was male and 8 was female; The median age was 54 years old. The pathological stage of radical nephrectomy included 14 cases of pT1-2N0M0 stage, 16 cases of pT3-4 N0M0 stage, and 3 cases of pN1 stage. Only 4 relapsing patients had symptoms, the others were all found to have recurrence by imaging examination during follow up period of postoperation.The median recurrence time for all patients was 30 months, and the median diameter of recurrent tumors was 4.5 cm.Twenty-nine patients underwent complete resection of local recurrent lesions, and 4 patients whose recurrent lesions could not be completely resected converted receive palliative surgery. The median intraoperative blood loss was 500 ml and the median hospital stay after surgery was 4 days. Clavien grade Ⅰ-Ⅱ complications occurred in 5 patients after surgery, and no serious complications of Clavien grade Ⅲ-Ⅴ complications occurred. Six patients received postoperative adjuvant target therapy and distant metastasis occurred in one patient.In the 27 patients without adjuvant target therapy, postoperative distant metastases occurred in 12 patients. The median survival time for all patients after local recurrence surgery was 31 months. The 1-year and 3-year survival rates were 86.8% and 36.9%, respectively. Conclusions: The rigorous imaging examination after radical nephrectomy can detect local recurrent lesions as early as possible in most relapsing patients and imaging examination can predict the integrity of surgical resection of local recurrence.Although intraoperative bleeding of resection of local recurrence is relatively high, the operation is safe and the postoperative complications are controllable. Postoperative adjuvant therapy may also provide better survival benefit for patients with local recurrence.

Abstract
AIM To evaluate whether elastic (stiffness) characteristics of tumours were associated with treatment responses and survival of patients with hepatocellular carcinoma (HCC) treated with transarterial chemoembolisation (TACE). MATERIALS AND METHODS A retrospective cohort study of 59 HCC patients with unresectable HCC who underwent TACE was undertaken. Acoustic radiation force impulse imaging (ARFI) was used to measure tissue stiffness of the index tumours and non-tumoural liver before TACE treatment. The correlation between the parameters of tumour stiffness and treatment response to TACE was assessed using mRECIST criteria as well as according to patient survival. RESULTS Tumour stiffness and its stiffness difference between tumour and non-tumoural liver were significantly associated with tumour response to TACE (p=0.019 and 0.010, respectively). Patients with tumour stiffness of <2 m/s or stiffness difference between tumour and non-tumoural liver of <0.5 were more likely to have treatment response to TACE. Univariate analysis showed that the difference in stiffness between tumour and non-tumoural livers (p=0.039) was one of the significant predictors of overall survival (OS). In multivariate analysis, alpha-fetoprotein (AFP) (p=0.006) and Barcelona Clinic Liver Cancer (BCLC) stage (p=0.017) were identified as independent predictors of survival. CONCLUSION Tumour stiffness characteristics might be an added predictive marker of treatment response to TACE in patients with HCC.
