Abstract
Objective: To investigate the influence of varied oxygen (O2) concentration environments on the phenotypic transformation of pulmonary artery smooth muscle cells (PASMC) and the mechanism of pulmonary hypertension. Methods: Primary rat PASMC were isolated and cultured through the process of enzymatic digestion. Following identification, the stable passaged PASMC were subjected to a 6-hour incubation in sealed containers with normal O2 content (group C) and relative O2 content comprising 55% (group H55), 75% (group H75), and 95% (group H95). mRNA and protein expression of α-Actin (α-SMA), smooth muscle 22α (SM22α), osteopontin (OPN), and matrix metalloproteinase-2 (MMP-2) were measured using real-time quantitative PCR and western blot analysis. Results: The H55 group displayed no significant difference from the C group in terms of mRNA and relative protein expression levels for α-SMA, SM22α, OPN, and MMP-2 (all P>0.05). On the other hand, groups H75 and H95 exhibited a reduction in mRNA and relative protein expression of α-SMA and SM22α, along with an increase in mRNA and relative protein expression of OPN and MMP-2 when compared with both the C and H55 groups (all P<0.05). The H95 group showed a higher relative mRNA expression of MMP-2 as compared to the H75 group (P<0.05). Conclusions: Oxygen concentration environments of 75% or higher can serve as the foundation for the pathogenesis of pulmonary hypertension, essentially by inducing a phenotypic transformation in PASMC towards adopting a robust secretory function. This induction is contingent upon the concentration of oxygen present.

Abstract
Peripheral T cell lymphoma (PTCL) is a heterogeneous group of non-Hodgkin's lymphomas varying in clinical, phenotypic, and genetic features. The molecular pathogenesis and the role of the tumor microenvironment in PTCL are poorly understood, with limited biomarkers available for genetic subtyping and targeted therapies. Through an integrated genomic and transcriptomic study of 221 PTCL patients, we delineate the genetic landscape of PTCL, enabling molecular and microenvironment classification. According to the mutational status of RHOA, TET2, histone-modifying, and immune-related genes, PTCL is divided into 4 molecular subtypes with discrete patterns of gene expression, biological aberrations, and vulnerabilities to targeted agents. We also perform an unsupervised clustering on the microenvironment transcriptional signatures and categorize PTCL into 4 lymphoma microenvironment subtypes based on characteristic activation of oncogenic pathways and composition of immune communities. Our findings highlight the potential clinical rationale of future precision medicine strategies that target both molecular and microenvironment alterations in PTCL.

Abstract
Objective: To investigate the correlation between dyslipidemia and the risk of papillary thyroid carcinoma (PTC). Methods: A case-control study was conducted. PTC patients diagnosed by pathology in Tianjin Medical University Cancer Institute and Hospital from April 2014 to August 2019 were enrolled as the experimental group, and healthy controls in the physical examination center at the same time were also enrolled as the control group. The demographic data and blood lipid parameters of the subjects were collected. Multivariate logistic analyses were used to assess the correlation between dyslipidemia and the risk of PTC. Results: A total of 2 000 cases of PTC were enrolled, with a mean age of (42±12) years, including 1 419 females (71.0%) and 581 males (29.0%). There were 4 524 cases in the control group, with a mean age of (42±9) years, including 3 311 females (73.2%) and 1 213 males (26.8%). There was no statistically difference in age and gender between the two groups (both P>0.05). Compared with the control group, triglyceride (TG) [(1.7±1.1) vs (1.4±1.0) mmol/L, P<0.001] and low-density lipoprotein (LDL) [(2.9±0.8) vs (2.8±0.7) mmol/L, P=0.015] increased in peripheral blood of PTC patients, while high-density lipoprotein (HDL) [(1.3±0.4) vs (1.4±0.3) mmol/L, P<0.001] decreased, but the difference was not statistically significant in total cholesterol (TC) [(4.9±1.0) vs (4.9±0.8) mmol/L, P=0.172]. After adjusting for age and gender, increase of TC (OR=1.20, 95%CI: 1.06-1.34, P=0.003), TG (OR=1.73, 95%CI: 1.55-1.94, P<0.001), LDL (OR=1.21, 95%CI: 1.08-1.36, P=0.001), LDL/HDL (OR=1.77, 95%CI: 1.56-2.02, P<0.001) and decrease of HDL (OR=3.15, 95%CI: 2.78-3.58, P<0.001) were the related factors of PTC. Conclusions: Compared with the control group, patients with PTC have higher level of TG and LDL and lower level of HDL. Dyslipidemia is an important factor related to the risk of PTC.

Abstract
Objective: To analyze the correlations between serum thyroglobulin antibody (TgAb) and thyroid peroxidase antibody (TPOAb) and clinicopathological features in children and adolescents with papillary thyroid carcinoma (PTC). Methods: A retrospective analysis was conduced on the clinicopathological data of children and adolescents (age≤21 years old) with PTC admitted to Tianjin Medical University Cancer Hospital from 2011 to 2019, and then, we used χ2 test or Fisher's exact probability test to compare the differences in clinicopathological characteristics between groups with different TgAb and TPOAb status and multivariate logistic regression model analysis to evaluate independent predictors of cervical lymph node metastasis. Results: A total of 304 patients, including 89 males and 215 females, aged 5-21 years (median age 19 years), were enrolled in this study. The comparison between groups with different TgAb and TPOAb status showed that there were significant differences in gender, preoperative thyroglobulin (Tg) level, primary tumor location, number of primary tumors and maximum tumor diameter (all P<0.05), which suggested that TgAb+group (n=81) and TPOAb+group (n=84) had relatively better primary tumor characteristics. Patitents with TgAb+and TPOAb+were more common in females and their preoperative Tg level was mostly within the normal range, and there were significant differences in primary tumor location, number of primary tumors and maximum tumor diameter between TgAb+and TgAb-(223 cases) groups (all P<0.05). There was significant difference in the maximum tumor diameter between TPOAb+and TPOAb-(220 cases) groups (P<0.05). Analysis of risk factors for cervical lymph node metastasis showed that independent risk factors for central lymph node metastasis were maximum tumor diameter>2 cm (OR=2.84, 95%CI: 1.59-5.07, P<0.001) and extra-thyroid extension (OR=0.32, 95%CI: 0.17-0.60, P<0.001), and independent risk factors for lateral neck lymph node metastasis included age≤14 years old (OR=0.34, 95%CI: 0.18-0.67, P=0.002), preoperative Tg+(OR=2.16, 95%CI: 1.10-4.24, P=0.026) and maximum tumor diameter>2 cm (OR=3.99, 95%CI: 2.33-6.82, P<0.001). Conclusion: It is recommended to test routinely serum TgAb and TPOAb before surgery in children and adolescents with PTC. Preoperative Tg+, age≤14 years, maximum tumor diameter>2 cm, and extra-thyroid extension are risk factors for cervical lymph node metastasis.

Abstract
Lung cancer is one of the most common malignant tumors with growing morbidity and mortality worldwide. Several treatments are used to manage lung cancer, including surgery, radiotherapy and chemotherapy, as well as molecular-targeted therapy. However, the current measures are still far from satisfactory. Therefore, the current research should focus on exploring the molecular mechanism and then finding an effective treatment. Interestingly, we and others have embarked on a line of investigations focused on the mechanism of lung cancer. Specifically, lncRNA small nucleolar RNA host gene has been shown to be associated with biological characteristics and therapeutic resistance of lung cancer. In addition, small nucleolar RNA host genes may be used as diagnostic biomarker in the future. Herein, we will provide a brief review demonstrating the importance of small nucleolar RNA host genes in lung cancer, especially non-small cell lung cancer. Although lncRNA has shown a crucial role in tumor-related research, a large number of studies are needed to validate its clinical application in the future.

Abstract
OBJECTIVE To investigate the genetic variations of Toxascaris leonina isolates from different hosts in Jiuquan City, Gansu Province. METHODS The mitochondrial sequences of partial mitochondrial nicotinamide adenine dinucleotide dehydrogenase subunit 1 (pnad1) and pnad5 of eleven T. leonina isolates from domestic dogs, foxes and pet dogs in Jiuquan City, Gansu Province, were amplified using PCR, and the amplification product was sequenced. The genetic variations of pnad1 and pnad5 genes in T. leonina isolates were analyzed. RESULTS The sequences of T. leonina pnad1 and pnad5 genes measured 530 bp and 550 bp in size, respectively. The nucleotide sequence homology was 99.4% to 100.0% for T. leonina pnad1 gene and 99.5% to 99.8% for T. leonina pnad5 gene, and the sequences of T. leonina pnad1 and pnad5 genes shared 99.2% to 99.9% and 99.1% to 99.9% with corresponding sequences of known T. leonina isolates. In addition, there were 19 and 24 polymorphic sites detected in the sequences of T. leonina pnad1 and pnad5 genes, with 10 and 9 haplotypes, haplotype diversity of 0.982 and 0.964 and nucleotide diversity of 0.039 4 and 0.034 2, respectively. Phylogenetic analysis based on pnad1 and pnad5 gene sequences showed that the eleven T. leonina isolates and known T. leonina isolates were clustered into the same branch with a random distribution, which were close to the branch where Toxocara canis was clustered, and far from the branch where other Ascaris species were clustered. CONCLUSIONS There is a minor genetic variation in pnad1 and pnad5 genes of T. leonina isolates from different hosts in Jiuquan City, Gansu Province, and the pnad1 gene is more suitable as a molecular marker than pnad5 gene for analysis of genetic variations in T. leonina.

Abstract
Objective: To investigate the application of GBZ/T 220.2-2009 "The Specification of Radiological Protection Assessment for Occupational Hazard in Construction Project-Part 2: Radiotherapy Facility" in health management institutions, and to understand the scientificity, practicability and problems existing in the implementation of the standard. Methods: The method of multistage stratified sampling and questionnaire survey were used to collect the standard application status among 96 radiological health managers who had participated in the evaluation of radiotherapy facility construction projects in 6 provinces and cities from November 2020 to April 2021. A descriptive statistical analysis method was used to analyze the basic information of the survey object, the knowledge of the standard, the publicity and implementation of the standard. Results: The radiological health management personnel mainly came from health supervision agencies (62.5%, 60/96) , and 86.5% (83/96) were engaged in the pre-evaluation of radiotherapy device construction project and the approval and supervision of control effect evaluation. The awareness rate and training rate of radiological health managers on GBZ/T 220.2-2009 were 88.5% (85/96) and 31.3% (30/96) , respectively. 89.6% (86/96) managers thought it could meet the needs of radiotherapy facility construction project approval or supervision. 49.0% (47/96) of managers believed that the standard needed to be revised. Conclusion: The content of GBZ/T 220.2-2009 is basically scientific and reasonable, but the publicity, implementation and training of radiological health administrator still need to be strengthened. It is suggested to revise some clauses in the standard that do not meet the requirements.

Abstract
Nine patients with large complex paraclinoid aneurysms were treated by hybrid surgery in the Second Affiliated Hospital of Zhejiang University between January 2016 and July 2021. Intraoperative angiography was conducted for real-time evaluation of the aneurysm and its clipping efficacy. A total of 8 aneurysms were clipped under temporary proximal control with balloon occlusion. Suction decompression was simultaneously applied in 2 of these cases. After surgery, 2 patients developed symptomatic cerebral infarction, 3 patients developed transient oculomotor nerve palsy, but no patients had vision deterioration. Postoperative follow-up showed that small neck residue occurred in 1 case, but with the rest of aneurysms were completely occluded without parent artery stenosis. Hybrid surgery was proved to be advantageous in real-time assessment of aneurysm morphology and clipping efficacy. Combination of temporary proximal balloon occlusion and suction decompression technique can help in reducing the difficulty of aneurysm exposure and remodeling, thereby improving the outcome and decreasing the complications.

Abstract
Objective: To compare the immunogenicity of three kinds immunization programs with poliovirus vaccine. Methods: Healthy infants aged 2 months or over were selected and divided into three groups by complete randomization method. Basic immunization with Sabin inactivated poliovirus vaccine(sIPV) and bivalent oral poliovirus vaccine(bOPV) were completed. Three kinds of basic immunization procedures were 1sIPV+2bOPV,2sIPV+1bOPV and 3sIPV, respectively.Two qualified serums that before basic immunization and 28-42 days later were collected, and measured the poliovirus neutralizing antibody with microcell neutralization method. To compare the difference by analysis of variance, rank test and χ2 test. Results: After the basic immunization, 205 subjects of the positive conversion rate of poliovirus neutralizing antibodies of types Ⅰ, Ⅱ and Ⅲwere all higher than 97.00%, and the positive rates were all higher than 98.00%, the geometric mean titer (GMT) of neutralizing antibody was significantly higher than that before basic immunization in three groups.There were significant differences in the positive rate and GMT before and after basic immunization of typeⅠ, Ⅱand Ⅲ in the three (P<0.05). The highest GMT in three groups after basic immunization were all typeⅠ, followed by type Ⅲ, and the lowest in type Ⅱ. The GMT of type Ⅱin 2sIPV+1bOPV and 3sIPV groups were both higher than that in sIPV+2bOPV group. Conclution: After three kinds of basic immunization, the poliovirus neutralizing antibodies of serum were all at high levels in three groups, which could form an effective immune barrier against poliovirus. The immunogenicity of three kinds of basic immunization programs were all well, but there were certain differences of neutralizing antibodies among three kinds basic immunization programs. The immunogenicity in 2sIPV+1bOPV and 3sIPV groups against typeⅡpoliovirus were better than that in 1sIPV+2bOPV group.

Abstract
BACKGROUND Spermatogonia in testis is sensitive to the cytotoxicity of chemotherapy agents. Cryopreservation of testicular tissue may offer fertility restoration in young male cancer survivors. OBJECTIVE To investigate the effect of melatonin on the survival of testicular grafts following cryopreservation and transplantation. MATERIALS AND METHODS Wister rats were randomly allocated into three groups: control group; saline group (cryopreservation + autograft + saline); and melatonin group (cryopreservation + autograft + melatonin). Malondialdehyde (MDA) content, glutathione peroxidase (GPx) activity and superoxide dismutase (SOD) activity were assessed on day 7 after autograft transplantation. At day 30, graft recovery, spermatogonia per round tubule, and serum testosterone concentration in grafts were measured. RESULTS Melatonin significantly diminished MDA content, enhanced GPx and SOD activities. Furthermore, the recovery rate, number of spermatogonia per round tubule, and serum testosterone concentration in melatonin group was markedly higher than the saline group. CONCLUSION Melatonin administration at 20 mg/kg is effective in improving the function of frozen and thawed rat testicular graft. The protective role of melatonin can be attributed partly to the enhanced ROS scavenging and antioxidant enzyme activities. doi.org/10.54680/fr22310110612.

Abstract
OBJECTIVE To verify the superiority of Fu's acupuncture for cervical spondylosis of vertebral artery type (CSA) based on Cheng's Tongtuo method. METHODS A total of 150 patients with CSA were randomly divided into a Tongtuo Fu's acupuncture group, a Tongtuo acupuncture group and a conventional Fu's acupuncture group, 50 cases in each group. Under the guidance of the theory of Tongtuo method, the Tongtuo Fu's acupuncture group was treated with Fu's acupuncture, the distal Tong method was performed at the distal myofascial trigger point (MTrP) of the dorsal forearm, and then the Tuo method was performed at the proximal MTrP of the cervical muscle group. In the Tongtuo acupuncture group, acupuncture was given at distal acupoints (Neiguan [PC 6], Quchi [LI 11], Taichong [LR 3], Xingjian [LR 2], etc.), and then at proximal acupoints (Fengchi [GB 20] and Baihui [GV 20]). In the conventional Fu's acupuncture group, Fu's acupuncture was only performed at the MTrP of cervical muscle group. Each group was treated once a day, 3 days were taken as one course, and 2 courses were given. The score of cervical vertigo symptoms and function evaluation scale, peak systolic velocity (PSV) and resistance index (RI) of vertebral artery were observed before and after treatment in the 3 groups. RESULTS After treatment, the scores of cervical vertigo symptoms and function evaluation scale and PSV in each group were higher than those before treatment (P<0.01), and the RI was lower than that before treatment (P<0.01). The score of cervical vertigo symptoms and function evaluation scale and PSV in Tongtuo Fu's acupuncture group were higher than those in the other two groups (P<0.01), and the RI was lower than that in the other two groups (P<0.01). CONCLUSION Fu's acupuncture based on Tongtuo method could improve the symptoms of cervical vertigo and the blood flow state of vertebral artery in patients with CSA, and the curative effect is better than Tongtuo acupuncture and conventional Fu's acupuncture.

Abstract
OBJECTIVE To investigate the characteristics of platelet antibody in patients with hematological diseases, so as to research the effect of immunized platelet transfusion refractoriness (PTR) on the prognosis of allogeneic hematopoietic stem cell transplantation (allo-HSCT) recepients with malignant hematological diseases patients. METHODS The clinical data of platelet antibody positive patients tested by Capture-P in the First Affiliated Hospital of Soochow University from July 1, 2014 to July 1, 2019 were retrospectively analyzed, including sex, age, disease, platelet transfusion assessments, CD34+ cells, transplant prognosis, and so on. RESULTS In 5 years, 913 (7.28%) hematologic patients with platelet antibody positive were identified, the detection rate of females (513 cases) were higher than males (400 cases). Among the 913 patients, the antibody positive rates of 520 patients with malignant hematological diseases (acute myeloid leukemia, acute lymphoblastic leukemia and myelodysplastic syndrome) showed significantly statistical different (10.27%, 8.01%, and 7.20%) (P<0.01), and the positive rate of the acute myeloid leukemia of those patients was higher than myelodysplastic syndrome patients(α<0.0125). There were 35 cases diagnosed as immunized PTR before allo-HSCT, the platelet increments, 14 h correct count increment, progression-free survival rate and overall survival rate of those patients were significantly lower than those in negative transfusion effective patients (P<0.01), while the percentage of ABO matching was significantly higher (α<0.0125). CONCLUSION The positive rate of platelet antibody identification is high in females and acute myeloid leukemia patients, and immunized PTR caused by antibody is a risk factor for poor prognosis of allo-HSCT in malignant hematological disease patients.

Abstract
Objective: To study the intestinal flora specific differences with different lesional stages of metabolic (disorder) associated fatty liver disease (MAFLD), namely simple steatosis and steatohepatitis, so as to provide a new direction for MAFLD-related intestinal flora transplantation and targeted therapy. Methods: Mice were fed with normal diet, methionine-choline deficient diet (MCD) and a high-fat high-fructose diet (HFHF) for 12 weeks to construct simple steatosis and steatohepatitis models. HE and Sirius scarlet staining was performed to observe the liver pathological changes. The qPCR method was used to evaluate inflammation and liver fibrosis factors. A fully automatic biochemical analyzer was used to detect changes in liver transaminase and blood lipids. 16S rRNA sequencing method was used to observe the intestinal flora differences in the feces of each group of mice. The comparison of means between two groups was performed by t-test, and the comparison of means between multiple groups was performed by one-way analysis of variance. Kruskal-Wallis rank sum test was used for non-normally distributed data. Results: NAFLD scores were determined with pathological sections (HE and Sirius scarlet staining) of mice liver, which showed that the inflammation and liver fibrosis scores of the MCD and HFHF groups were 2.12 ± 0.18 and 1.06 ± 0.24, and 2.22 ± 0.16 and 0.46 ± 0.10, respectively. The degree of liver inflammation and fibrosis was significantly higher in the MCD than the HFHF group (P < 0.001 and P < 0.01). Lipid deposition was higher in the HFHF than the MCD group (P < 0.001), and the scores were 2.36 ± 0.17 and 1.60 ± 0.24 respectively. Simultaneously, the inflammatory [tumor necrosis factor-A (TNF-a), chemokine factor-2 (CXCL-2)] and hepatic fibrosis indicators [vascular smooth muscle actin alpha (a-SMA) and connective tissue growth factor (CTGF)] had confirmed the above-mentioned results at the transcription level. Moreover, the intestinal flora diversity was reduced (P < 0.05) in the MCD group than the HFHF group, and the Simpson and Shannon index were 0.31 ± 0.10 and 0.42 ± 0.05, and 2.03 ± 0.33 and 1.70 ± 0.28, respectively, and the differences were significant between different intestinal flora groups. The levels of Desulfovibrio, Odoribacter, and Roseburia flora were significantly increased in the HFHF than the MCD group, and the levels of Faecalibaculum, Parasutterella, Alipis, Butyricimonas_virosa, Turicibacter_sp, and Romboutsia_ilealis were significantly increased in the MCD than the HFHF group, and the difference was statistically significant (P < 0.05). Conclusion: There are significant differences in intestinal flora diversity between simple steatosis and steatohepatitis models. Therefore, clarifying the difference between the two may provide a new direction for the stage manner treatment of MAFLD.

Abstract
Oriented external electric fields are now emerging as "smart effectors" of chemical changes. The key challenges in experimentally studying electrostatic catalysis are (i) controlling the orientation of fields along the reaction axis and (ii) finely adjusting the magnitudes of electrostatic stimuli. Surface models provide a versatile platform for addressing the direction of electric fields with respect to reactants and balancing the trade-off between the solubility of charged species and the intensity of electric fields. In this mini-review, we present the recent advances that have been investigated of the electrostatic effect on the chemical reaction on the monolayer-functionalized silicon surfaces. We mainly focus on elucidating the mediator/catalysis role of static electric fields induced from either solid/liquid electric double layers at electrode/electrolyte interfaces or space charges in the semiconductors, indicating the electrostatic aspects is of great significance in the semiconductor electrochemistry, redox electroactivity, and chemical bonding. Herein, the functionalization of silicon surfaces allows scientists to explore electrostatic catalysis from nanoscale to mesoscale; most importantly, it provides glimpses of the wide-ranging potentials of oriented electric fields for switching on/off the macroscale synthetic organic electrochemistry and living radical polymerization.

Abstract
Objective: To explore the indications, selection, and effect of flap application in repairing scar carcinoma in the lower leg and ankle. Methods: A retrospective cohort study was conducted. From June 2008 to December 2018, six male patients with scar carcinoma in the lower leg and ankle were treated in Sun Yat-Sen Memorial Hospital of Sun Yat-Sen University, aged 48-64 years, with the area of lesion ranging from 3 cm×2 cm to 15 cm×6 cm. After extended resection, the defect area ranged from 8 cm×5 cm to 22 cm×9 cm, with tissue of tendon or bone exposed. Free anterolateral thigh perforator flap, latissimus dorsi myocutaneous flap, or pedicled sural neurovascular flap was selected to repair the wound according to the location of wound in the lower extremity, selection of operation position, the location of the anastomotic vessels in the recipient area, and whether there was good skin and soft tissue available in the lower leg. The size of flap was 11 cm×8 cm-26 cm×10 cm. The donor site of free flap or myocutaneous flap was closed directly by suturing in 5 cases, and the donor site of pedicled flap was repaired with full-thickness skin graft in 1 case. The blood supply and survival of flap, quality of skin graft survival, and complication were observed postoperatively. During the follow-up period, the recurrence and metastasis of scar carcinoma, and the appearance and function of donor and recipient sites were observed. Results: All the patients completed the operation successfully, all the transplanted flaps survived with good blood supply, and the skin graft in one donor site survived well. The wounds in the donor and recipient sites of all the patients healed well without infection, effusion, or dehiscence, etc. All the patients were followed up for 1-5 years. No local recurrence or distant metastasis of scar carcinoma was found. The quality of the transplanted flaps was good. The shape of the recipient area was quite good, and the function of the affected limb was fine. The appearance of the donor area was good without dysfunction. Conclusions: Flap transplantation is suitable for the patients with tendon and bone exposure after the excision of scar carcinoma in the lower leg and ankle. The flap can be selected according to the location of scar carcinoma, operation position, the location of anastomotic vessels in the recipient area, and whether there is good skin and soft tissue available in the lower leg. The free anterolateral thigh perforator flap or latissimus dorsi myocutaneous flap is an ideal choice for repair, which can be obtained in a large area, and the donor site can be directly sutured without affecting the function.

Abstract
Acute myeloid leukemia (AML) is still incurable due to its heterogeneity and complexity of tumor microenvironment. It is imperative therefore to understand the molecular pathogenesis of AML and identify leukemia-associated biomarkers to formulate effective treatment strategies. Here, we systematically analyzed the clinical characters and natural killer (NK) cells portion in seventy newly-diagnosis (ND) AML patients. We found that the proportion of NK cells in the bone marrow of ND-AML patients could predict the prognosis of patients by analyzing the types and expression abundance of NK related ligands in tumor cells. Furthermore, MCL1 inhibitor but not BCL2 inhibitor combined with NK cell-based immunotherapy could effectively improve the therapeutic efficiency via inhibiting proliferation and inducing apoptosis of AML primary cells as well as cell lines in vitro. There results provide valuable insights that could help for exploring new therapeutic strategies for leukemia treatment.

Abstract
BACKGROUND Several obstacles must be overcome before ovarian tissue cryopreservation can be used as a standard procedure. OBJECTIVE To carry out a morphologic and functional study of the effect of cryopreservation on mouse follicles and stroma cells. MATERIALS AND METHODS Female mice were divided into three groups (control, fresh graft and cryopreserved graft). Ultrastructural features of follicles and stroma cells were evaluated using transmission electron microscopy. After autologous transplantation, micro-vessel densities of grafts were examined. RESULTS Vacuoles in granulosa cells and stromal cells are significantly greater than that of oocytes. The microvessel density of fresh grafts is significantly higher than that in frozen-thawed grafts. CONCLUSION Granusola and stroma cells, rather than oocytes, are vulnerable to cryoinjury. Injuries to granulosa cells and stromal cells could be the critical part of ovarian damage caused by cryopreservation.

Abstract
Objective: To evaluate the cost effectiveness of primary prophylaxis (PP) with pegylated recombinant human granulocyte colony stimulating factor (PEG-rhG-CSF), PP with recombinant human granulocyte colony stimulating factor (rhG-CSF) and no prophylaxis in women with early-stage breast cancer in China. Methods: Two phase Markov models were constructed for a hypothetical cohort of patients aged 45 with stage Ⅱ breast cancer. The first phase modelled costs and outcomes of 4 cycles docetaxel combined with cyclophosphamide [TC×4, febrile neutropenia (FN) risk>20%] chemotherapy, which assumptions based on literature reviews, including FN rates [base-case (deterministic sensitivity analysis range), 0.29 (0.24-0.35)] and related events [FN case-fatality, 3.4 (2.7-4.1)]. Second phase modelled the long term survival which was link with the relative dose intensity (RDI) [mortality hazard ratio (HR) of RDI < 85% vs ≥85%, 1.45 (1.00-2.32)]. Clinical effectiveness, therapeutic costs, and economic utilities were estimated from peer-reviewed publications and expert opinions in case of unavailability of published evidences. Results: Compared to rhG-CSF PP and no prophylaxis, the cost of PEG-rhG-CSF PP increased to 5 208.19 RMB and 5 222.73 RMB, respectively. The quality-adjusted life-years (QALYs) enhanced to 0.066 and 0.297, respectively. Accordingly, the incremental cost effectiveness ratios (ICERs) are 79 146.3 RMB and 17 558.77 RMB per QALY, which were both below the willingness to pay (WTP) threshold of three times GDP per capita (18, 000 RMB) recommended by the WHO. Sensitivity analysis suggested that the more clinically effective the primary prophylaxis with PEG-rhG-CSF is, the more cost-effective primary prophylaxis with PEG-rhG-CSF will be. And the lower the mortality HR of RDI<85% vs ≥85% is, the more cost-effective primary prophylaxis with PEG-rhG-CSF will be. Conclusion: Although the cost of PP PEG-rhG-CSF is higher, considering the additional benefits, the administrating of PP PEG-rhG-CSF is likely to be a cost-effective alternative to PP rhG-CSF and no prophylaxis in patients with early stage breast cancer whose FN risks are more than 20% in China.

Abstract
OBJECTIVE To observe the short-term and long-term clinical effect on posterior circulation ischemic vertigo treated with "xiao xingnao kaiqiao" acupuncture (minor regaining consciousness and opening orifice) and explore its effect mechanism. METHODS Ninety patients with posterior circulation ischemic vertigo were randomly divided into a treatment group and a control group, 45 cases in each group. The patients of the two groups were all treated on the base of neurological medicine. In the control group, Flunarizine Hydrochloride was prescribed for oral administration (5 mg, once daily, for 21 days totally). In the treatment group, acupuncture of "xiao xingnao kaiqiao" was provided at Yintang (EX-HN3), bilateral Neiguan (PC6), bilateral Sanyinjiao (SP6), Baihui (GV20), bilateral Fengchi (GB20), bilateral Wangu (GB12) and bilateral Tianzhu (BL10). The needles were retained for 30 min, once daily for 21 days totally. The changes in vertigo score of traditional Chinese medicine (TCM) were observed, and the changes in the mean blood velocity (Vm) of the left vertebral artery (LVA), the right vertebral artery (RVA) and the basilar artery (BA) as well as the vascular pulsatility index (PI) were monitored and determined by transcranial Doppler (TCD). Additionally, the recurrence rate was followed up after 3 months to evaluate the long-term clinical effects. RESULTS After treatment, the total effective rate of the treatment group was 91.11% (41/45) and 75.56% (34/45) in the control group. The total effective rate in the treatment group was higher than that in the control group (P<0.05). Compared with their own pre-treatment, the vertigo scores of TCM were reduced in either the treatment group or the control group after treatment (P<0.05) and the score in the treatment group was lower than that in the control group (P<0.05). Compared with their own pre-treatment, Vm and PI were all improved after treatment in either group (P < 0.05). After treatment, the improvements in Vm and PI of LVA、RVA and BA in the treatment group were better than those in the control group (P<0.05). In the follow-up after 3 months, the recurrence rate was 19.51% (8/41) in the treatment group and was 50.00% (17/34) in the control group. The recurrence rate in the treatment group was lower than that in the control group (P<0.05). CONCLUSION "Xiao xingnao kaiqiao" acupuncture obviously relieves the clinical symptoms of posterior circulation ischemic vertigo. The mechanism of acupuncture is potentially related with its effects in improving Vm and PI of LVA,RVA and BA, as well as improving blood supply of brain tissue.

Abstract
Medical gas is a large class of bioactive gases used in clinical medicine and basic scientific research. At present, the role of medical gas in neuroprotection has received growing attention. Stroke is a leading cause of death and disability in adults worldwide, but current treatment is still very limited. The common pathological changes of these two types of stroke may include excitotoxicity, free radical release, inflammation, cell death, mitochondrial disorder, and blood-brain barrier disruption. In this review, we will discuss the pathological mechanisms of stroke and the role of two medical gases (hydrogen and hydrogen sulfide) in stroke, which may potentially provide a new insight into the treatment of stroke.

Abstract
BACKGROUND Blockage of mTOR1 can inhibit the transformation of primordial follicles into growing follicles in the ovaries. OBJECTIVE The aim of this study was to investigate the role of mTORC1 inhibition in the cryopreservation and transplantation of mouse ovarian tissues. MATERIALS AND METHODS ICR (Institute of Cancer Research) mice were randomly divided into control group (autograft), cryopreservation group (cryopreservation + autograft), and mTORC1 inhibition group (cryopreservation + autograft + mTOR inhibitor). After 30 days of auto-transplantation, the follicle number of graft and kit ligand (KL) immunostaining in grafts were quantified. In addition, serum concentration of anti-Müllerian hormone (AMH) was examined by ELISA. RESULTS The graft in mTORC1 inhibition group showed a significantly higher proportion of primordial follicles and a significantly lower proportion of growing follicles compared with cryopreservation group. Furthermore, a significant decrease in expression of KL (a marker gene related to follicular development) was observed in mTORC1 inhibition group in contrast to cryopreservation group. The follicle number of graft and serum AMH concentration in mTORC1 inhibition group were significantly higher than that in cryopreservation group. CONCLUSION Inhibition of mTORC1 signaling pathway is a valid therapeutic strategy in transplantation of cryopreserved mouse ovarian tissue via suppression of primordial follicle activation.

Abstract
BACKGROUND It has been shown that vitrified-warmed oocytes exhibit autophagic activation. However, its regulatory molecular mechanism of autophagy needs to be clarified. OBJECTIVE To determine the role of signaling pathway of PI3K/Akt/mTOR in the regulation of autophagy in oocytes during vitrification-warming and IVM. MATERIALS AND METHODS Oocytes from mice were vitrified-warmed and IVM. The expressions of LC3-II, Beclin-1, PI3K, Akt, and mTOR protein were determined. Moreover, the ATP level, viability of vitrified-warmed oocytes, and their developmental potential were measured. RESULTS At 6 h of incubation of warmed oocytes, the LC3-II and Beclin-1 expressions were markedly up-regulated, whereas PI3K, Akt, and mTOR proteins expressions were significantly down-regulated. In addition, autophagy inhibition significantly decreased ATP level, viability of oocytes, and their developmental potential. CONCLUSION Autophagy plays a protective role in the oocytes during vitrification-warming and IVM. The PI3K/Akt/mTOR pathway participated in regulating autophagy activity in oocyte during vitrification-warming and IVM.

Abstract
OBJECTIVE To evaluate the role of polysaccharide from Phellinus igniarius (PPI) in the improvement of oxidative stress, hepatic granuloma and hepatic fibrosis in Schistosoma japonicum-iniected in mice. METHODS The mouse model of schistosomiasis was established by S. japonicum cercariae infection via the abdomen. Balb/c mice were randomly assigned into 5 groups, including the healthy control group (Group A), infection control group (Group B), PPI treatment group (Group C), praziquantel treatment group (Group D) and PPI-praziquantel combination group (Group E), of 10 mice in each group. Each mouse in groups B, C, D and E was infected with (30 ± 2) S. japonicum cercariae. Then, mice in groups D and E were given praziquantel by gavage at a dose of 500 mg/kg for successive two days on day 42 post-infection, while mice in groups C and E were given PPI by gavage at a dose of 400 mg/kg for successive 30 days on day 42 post-infection. Histopathological changes of hepatic tissues were observed using hematoxylin-eosin (HE) staining, and serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), hyaluronic acid (HA), laminin (LN) were determined, while the activities of malondialdehyde (MDA), superoxide dismutase (SOD), glutathione peroxidase (GSH-PX), glutathione reductase (GSH-R) and glutathione (GSH) were detected in Mouse liver homogenates. The expression of transforming growth factor-beta (TGF-β) and alpha-smooth muscle actin (α-SMA) was quantified in hepatic tissues using immunohistochemistry, and the Nrf2 and Gsta4 gene expression was quantified using quantitative real-time PCR (qPCR) assay. RESULTS Untreated mice presented typical pathological changes of schistosomal hepatic disorders, while PPI treatment effectively alleviated hepatic egg granulomas and collagen deposition. S. japonicum infection resulted in aggravation of hepatic lipid peroxidation, induction of oxidative stress, elevated serum MDA level and a reduction in the activity of GSH and antioxidant enzymes activities in mice. As compared to infected but untreated mice, PPI treatment suppressed hepatic lipid peroxidation, increased the GSH activity and restored the activity of antioxidant enzymes. In addition, PPI treatment inhibited the TGF-β signaling pathway and up-regulated the Nrf2 and Gsta4 gene expression. CONCLUSIONS PPI plays a critical role in the treatment of schistosomiasis-induced hepatic fibrosis. It may improve oxidative stress damages through up-regulating Nrf2 and Gsta4 gene expression, thereby suppressing the development of hepatic egg granulomas and hepatic fibrosis.

Abstract
Objective: To provide scientific evidence for the prevention and control measures of silicosis by analyzing the epidemiological characteristics of silicosis cases reported in Tianjin city during 2001-2015. Methods: The database of silicosis cases reported in Tianjin from 2001 to 2015 was established and analyzed by SPSS 24.0 software. Results: 2 213 cases of silicosis were reported during 2001~2015 in Tianjin, 2015 of them were new cases, and fewer reports of promoting stage cases and death cases, which were129 and 69 cases. The new cases were increasing by years, mainly stage I silicosis accounting for 99.2%, the years of dust exposure were concentrated from 1970 to 1989, accounting for 69.58%. From 2001 to 2015, the median length of service at the onset of silicosis was 19.30 years, the age of the onset of silicosis is decreasing. The median of onset age in new cases of silicosis was 53.28 years, and increased year by year. There were significant differences in indirect dust working age and diagnostic age in different reporting years. Most cases were distributed in non-mental mineral product industry, and ferrous metal smelting and rolling processing industry. The work types of these cases are various. Conclusion: The increasing incidence of silicosis and the shortening of dust-exposed working years suggest that the form of silicosis hazards is still severe in Tianjin. According to the epidemic characteristics of silicosis, we should strengthen the supervision and management of key industries and special investigation, carry out silicosis census and silicosis screening of dust-removal workers, and take pertinent measures to prevent and control the occurrence of silicosis.

Abstract
Objective: To know condom use negotiation with clients and regular sex partners and condom use in female sex workers (FSWs), and provide reference for the development of comprehensive HIV/AIDS intervention for FSWs. Methods: The cross sectional survey was conducted in Jianshui county and Mengzi county in Honghe Hani and Yi autonomous prefecture. A total of 476 FSWs aged 16 years and above were recruited from entertainment venues, and the information about their demographic characteristics, condom use negotiation and condom use were collected by using questionnaires. Logistic regression model was used to analyze related factors of condom use after negotiation between FSWs and clients unwilling use condom. Results: A total of 852 FSWs who aged (24.29±8.44) years old participated in the survey. In past month, 499 FSWs had negotiation for condom use with unwilling clients (58.6%, 499/852), after negotiation, 441 FSWs (88.4%, 441/499) had consistent condom use in each sex with the clients. In the past one month, 99 FSWs had negotiation for unwilling use condom with regular sex partners (14.4%, 99/687), after negotiation, 54 FSWs (54.5%, 54/99) had consistent condom use in each sex with regular sex partners. Among the FSWs, 266 (53.3%, 266/499) reported that they could say "It is a mandatory requirement" to persuade clients who were unwilling to use condom. 97(19.4%, 97/499) reported that they could say "There is risk for infection" to persuade clients who were unwilling to use condoms. 115 (23.1%,115/499) reported that they could say "It is a mandatory requirement" and "there is risk for infection" to persuade their unwilling clients to use condoms. 21 (4.2%, 21/499) reported that they used other strategies. 22 (4.4%, 22/499) felt that it was difficult to persuade clients to use condoms. Multivariate logistic regression analysis showed that compared with FSWs who felt difficult in persuading clients to use condoms, FSWs who felt moderate difficulty were more likely to have consistent condom use after negotiation (OR=4.00, 95%CI: 1.55-10.32) and FSWs who felt easy in persuading clients to use condoms were also more likely to have consistent condom use (OR=30.17, 95%CI: 3.22-282.44). Compared with FSWs used other strategies to persuade their clients to use condoms, FSWs who said it was a mandatory requirement were more likely to have consistent condom use after negotiation (OR=4.44, 95%CI: 1.41-14.01) and FSWs who said it was a mandatory requirement and there was risk for infection were also more likely to have consistent condom use (OR=5.52, 95%CI: 1.55-19.73). Conclusions: Negotiation for condom use increased the rate of condom use in FSWs in sex with clients who were unwilling to use condom. The negotiation strategy of "It is a mandatory requirement" would promote condom use in FSWs in sex with clients who were unwilling to use condom. Besides, the negotiation strategy of saying "there is risk for infection" had additional effects.

Abstract
Objective:To evaluate the diagnostic value of circulating microRNAs in nasopharyngeal carcinoma by Meta-analysis. Method:A number of databases in Chinese and English were searched, and the clinical studies published from the day the datebases were set up to July 2018 on detecting microRNAs as biomarkers in the diagnosis of nasopharyngeal carcinoma were collected. Literature selection, data extraction and literature quality evaluation were carried out according to the criteria of exclusion and inclusion.Then Meta-disc,Stata,and other softwares were used for the Meta-analysis. Result:Eighteen eligible articles were collected for systematic review, of which 7 independent case-control studies from 6 articles including 706 NPC patients and 353 controls were selected in the Meta-analysis. Since the obvious heterogeneity among the studies was observed,we conducted this Meta-analysis by the random effect model. The pool sensitivity, specificity, positive likelihood ratio, negative likelihood ratio and area under curve of circulating microRNAs in the diagnosis of nasopharyngeal carcinoma were 0.78(95%CI: 0.75-0.81, 0.81(95%CI: 0.77-0.85), 5.71(95%CI: 2.49-13.11), 0.23(95%CI: 0.13-0.42), 30.88(95%CI: 7.91-120.59) and 0.913 1,which illustrated the high diagnostic accuracy and significant clinical utility of microRNAs in the diagnosis of nasopharyngeal carcinoma.Subgroup analysis showed that the source of samples,the number of cases,the amount of the detecting microRNAs and the type of control groups were the main reasons contributing to the significant heterogeneity. Conclusion:MicroRNAs as biomarkers in the diagnosis of nasopharyngeal carcinoma possess significant potential value. .

Abstract
Slingshot phosphatase 3 (SSH3) is a member of the SSH phosphatase family that regulates actin filament dynamics. However, its role in cancer metastasis is relatively unclear compared to that of SSH1. Here, we showed that SSH3 was upregulated in colorectal cancer (CRC). Of note, SSH3 was upregulated in the tumor thrombus and lymph node metastasis compared with that in paired primary CRC tissues. High SSH3 expression was associated with the aggressive phenotype of CRC and may be an independent prognostic factor for the poor survival of patients with CRC. SSH3 significantly enhanced the invasion and metastasis of CRC cells in vitro and in vivo. Moreover, SSH3 regulated the remodeling of actin, which is involved in the cytoskeleton signaling pathway, through its interaction with LIMK1/Rac1 and subsequently promoted CRC cell invasion and metastasis. Our data elucidate an important role for SSH3 in the progression of CRC, and SSH3 may be considered a potential therapeutic target for CRC.

Abstract
AIMS/OBJECTIVES We aimed to analyse the molecular backgrounds and red blood cell (RBC) antigen expression of a male blood donor with Rhmod phenotype and his family members. BACKGROUND Rh deficiency phenotypes are rarely found worldwide and are characterised by the lack of Rh antigen expression on RBCs. During routine screening, we found a blood donor who seemingly lacked Rh antigens. Therefore, we recruited the donor and his family for further investigation. METHODS RBC serotyping and antibody screening/identification were performed for each sample. A routine blood examination was also conducted. RHD, RHCE and RHAG were sequenced at the genomic DNA or RNA level. Eleven antigens or proteins associated with Rh complex were tested using flow cytometry analysis. RESULTS The proband and one of his brothers showed extremely weak D antigen and Rh expression levels but did not manifest anaemia. Most of the expressed RBC antigens of the two Rh-deficient individuals were similar to the previously reported cases but with some exceptions. Molecular analyses demonstrated homozygous expression of a novel RHAG allele, namely, c.[572G>A;707A>C], both in the proband and one of his brothers. CONCLUSIONS To our knowledge, we identified the second double-variant RHAG allele and the first one related to Rhmod phenotype. The novel allele was also confirmed to be heritable by family analyses.

Abstract
Objective: To investigate the clinical effect and safety of long-acting pegylated interferon-α-2b (Peg-IFN-α-2b) (Y shape, 40 kD) injection (180 μg/week) in the treatment of HBeAg-positive chronic hepatitis B (CHB) patients, with standard-dose Peg-IFN-α-2a as positive control. Methods: This study was a multicenter, randomized, open-label, and positive-controlled phase III clinical trial. Eligible HBeAg-positive CHB patients were screened out and randomized to Peg-IFN-α-2b (Y shape, 40 kD) trial group and Peg-IFN-α-2a control group at a ratio of 2:1. The course of treatment was 48 weeks and the patients were followed up for 24 weeks after drug withdrawal. Plasma samples were collected at screening, baseline, and 12, 24, 36, 48, 60, and 72 weeks for centralized detection. COBAS® Ampliprep/COBAS® TaqMan® HBV Test was used to measure HBV DNA level by quantitative real-time PCR. Electrochemiluminescence immunoassay with Elecsys kit was used to measure HBV markers (HBsAg, anti-HBs, HBeAg, anti-HBe). Adverse events were recorded in detail. The primary outcome measure was HBeAg seroconversion rate after the 24-week follow-up, and non-inferiority was also tested. The difference in HBeAg seroconversion rate after treatment between the trial group and the control group and two-sided confidence interval (CI) were calculated, and non-inferiority was demonstrated if the lower limit of 95% CI was > -10%. The t-test, chi-square test, or rank sum test was used according to the types and features of data. Results: A total of 855 HBeAg-positive CHB patients were enrolled and 820 of them received treatment (538 in the trial group and 282 in the control group). The data of the full analysis set showed that HBeAg seroconversion rate at week 72 was 27.32% in the trial group and 22.70% in the control group with a rate difference of 4.63% (95% CI -1.54% to 10.80%, P = 0.1493). The data of the per-protocol set showed that HBeAg seroconversion rate at week 72 was 30.75% in the trial group and 27.14% in the control group with a rate difference of 3.61% (95% CI -3.87% to 11.09%, P = 0.3436). 95% CI met the non-inferiority criteria, and the trial group was non-inferior to the control group. The two groups had similar incidence rates of adverse events, serious adverse events, and common adverse events. Conclusion: In Peg-IFN-α regimen for HBeAg-positive CHB patients, the new drug Peg-IFN-α-2b (Y shape, 40 kD) has comparable effect and safety to the control drug Peg-IFN-α-2a.

Abstract
Objective: To recognize the efficacy and safety of paritaprevir/ritonavir-ombitasvir combined with dasabuvir (OBV/PTV/RTV+DSV) in the treatment of genotype 1b chronic hepatitis C. Methods: Patients with genotype 1b chronic hepatitis C who were admitted to the People's Hospital of Henan Province, Huashan Hospital of Shanghai and the Fifth Medical Center of the General Hospital of the People's Liberation Army of China between November 2017 to August 2018 were enlisted. All patients received OBV/PTV/RTV+DSV antiviral therapy. HCV RNA levels were measured at baseline, weeks 1, 2, 3, 4, 8, 12, and 24, then 12 weeks, and 24 weeks after completion of treatment; patients' comorbidity, concomitant medications, and clinical adverse events were recorded. Results: 108 patients were enrolled in the study, with an average age of 49.1 years, 44 patients were male (40.8%), 96.3% (104/108) were newly diagnosed, and four patients had previous treatment history, of whom three were treated with IFN and one with IFN + DAA. Ninety-eight cases completed 12 weeks treatment and 89 cases were in follow up for 12 weeks, after discontinuation of the drug. Overall, 89 cases (100%) achieved SVR12.One patient treated with PR and DAA had HCV RNA level of 869175 IU/mL at 4 weeks of treatment, which was significantly higher than the baseline HCV RNA level (301776IU/ML), and was judged as failure of treatment; and follow-up was discontinued. Of all enrolled patients, 19 (17.6%) had underlying diseases and 15 (13.9%) had combined medications. During treatment, adverse events (AE) occurred in 11 patients (10.1%). The main adverse events were pruritus and elevated bilirubin. Conclusion: Combined antiviral therapy (OBV/PTV/RTV+DSV) of 12 weeks are highly effective with good safety profile in the treatment of Chinese patients with genotype 1b chronic hepatitis C.

Abstract
Clear cell renal cell carcinoma (ccRCC) is one of the most common types of kidney cancer and is accompanied by a poor prognosis due to a high potential for metastasis and recurrence. The mechanism of ccRCC metastasis is not well known. N-lysine methyltransferase KMT5A serves a crucial role in the progression of human cancer; however, the function of KMT5A in the development of ccRCCs has not yet been investigated, which has triggered an interest in investigating the potential association between KMT5A and ccRCC. The present study demonstrates for the first time that KMT5A is a driving factor in ccRCC metastasis. The KMT5A expression level was revealed to be significantly higher in ccRCC tissues compared with adjacent normal tissues. Patients with ccRCC whose tumors expressed high levels of KMT5A were demonstrated to have significantly shorter postoperative survival times. In vitro knockdown of KMT5A expression in 786-O cells inhibited cell migration and invasion. KMT5A reduced cadherin-1 (CDH1) protein levels by directly inhibiting its transcription. The CDH1 mRNA levels were inversely correlated with KMT5A expression in ccRCC samples. Patients with high tumor KMT5A or low CDH1 levels had the poorest prognosis with the shortest overall survival (OS) time, and this combination was demonstrated to be an independent prognostic indicator for patient OS time in ccRCC, more accurate than monitoring KMT5A or CDH1 alone. Together, these results indicate that KMT5A serves a vital role in ccRCC development and progression, and it may be a novel target for ccRCC treatment and prevention.

Abstract
Objective: To investigate the usage frequency of radiological diagnosis devices in ten hospitals in Tianjin, China, and to provide a basis for the survey of medical radiation frequency in Tianjin. Methods: Ten hospitals from the ten districts in Tianjin were enrolled as subjects by a convenient sampling method. A survey was conducted to assess the general information and radiological diagnosis device information and usage frequency in those hospitals in 2016. The radiological examination frequency in Tianjin was estimated. Results: A total of 610 458 patients received radiological examinations in the sampled hospitals in 2016. In those patients, 371 882 received X-ray examinations for imaging and 238 576 for computed tomography (CT) ; there were slightly more female patients than male patients, suggesting a relatively equal gender distribution; patients older than 40 years accounted for 65.53%, which was the highest among all the age groups. Different types of radiological diagnosis devices were mostly used in tertiary and secondary hospitals. In Tianjin, the estimated frequency of X-ray examination for imaging and CT scanning was 451 and 188 per thousand people, respectively, in 2016. Conclusion: The frequency of radiological diagnosis is relatively high in the ten hospitals in Tianjin. The investigation of medical radiation in Tianjin needs to be improved.

Abstract
Objective: To investigate the classification, possible risk factors, managements and clinical outcomes of suction loss in small incision lenticule extraction (SMILE). Methods: In this nested case control study, subjects undergoing SMILE surgery between September 2013 and September 2017 were enrolled in the study. Eyes suffered from suction loss were included in the suction loss group, and eyes without intraoperative complications and operated at the same date were included in the control group. The refraction and visual outcomes were evaluated at preoperative and postoperative 1 day, 1 week, 1, 3 and 6 months. Independent t test and Pearson relation analysis were used for statistical analysis. Results: The study included 206 cases (344 eyes), of which 25 cases (27 eyes) were in suction loss group and 181 cases (317 eyes) were in control group. Suction loss occurred at: (1) scanning posterior surface of lenticule (5, 18.5%); (2) scanning lenticule side cut (1, 3.7%); (3) scanning anterior surface of lenticule (16, 59.3%);(4) scanning incision (5, 18.5%). The main reasons included: (1) abnormal eye movement (14, 51.9%); (2) extra fluid on corneal surface (13, 48.1%). There was significant difference in cap diameter between two groups (t=2.341, P<0.05). At postoperative 3 months, 3.7% (1 eyes) of eyes in cases lost one line; 2.6% (6 eyes) of eyes in controls lost one line. 92.6% (25 eyes) and 91.3% (209 eyes) of eyes had a UCVA of 0.10 LogMAR or better in cases and controls, respectively; 85.2% (31 eyes) and 93.4% (214 eyes) of eyes had a residual SE between±0.50D in cases and controls, respectively. Conclusions: Suction lost during anterior surface of cornea was most common in SMILE surgery. Extra fluid in cornea surface, sudden eye movement of patient and larger corneal cap may result in suction loss. And it may slow the visual recovery, but appropriate and effective managements will be benefited to the final visual outcomes. (Chin J Ophthalmol, 2018, 54: 890-896).

Abstract
The progression of CRC is a multistep process involving several genetic changes or epigenetic modifications. NDN is a member of the MAGE family, encoding a protein that generally suppresses cell proliferation and acting as a transcriptional repressor. Immunohistochemical staining revealed that the expression of NDN was significantly down-regulated in CRC tissues compared with normal tissues and the down-regulation of NDN in CRC could reflect the hypermethylation of the NDN promoter. Treatment of the CRC cell line SW480 with the demethylating agent 5-Aza-CdR restored the NDN expression level. The down-regulation of NDN was closely related to poor differentiation, advanced TNM stage and poor prognosis of CRC. The inhibition of NDN promoted CRC cell proliferation by enriching cells in the S phase. Furthermore, we observed that NDN binds to the GN box in the promoter of LRP6 to attenuate LRP6 transcription and inhibit the Wnt signaling pathway in CRC. In conclusion, our study revealed that the hypermethylation of NDN promotes cell proliferation by activating the Wnt signaling pathway through directly increasing the transcription of LRP6 in CRC. These findings might provide a new theoretical basis for the pathogenesis of CRC and facilitate the development of new therapeutic strategies against CRC.

Abstract
BACKGROUND The aim of this study is to investigate whether 25-hydroxyvitamin D [25(OH) D] is associated with initial stroke severity and infarct volume, using diffusion-weighted imaging (DWI) in patients with acute ischemic stroke. METHODS We studied a total of 235 patients who were admitted within 24 hours of acute ischemic stroke onset. Initial stroke severity was assessed using the NIH Stroke Scale (NIHSS) score. Infarct volume was measured using DWI. Multivariable linear and logistic regression analyses were used to test whether 25(OH) D represents an independent predictor of infarct volume and stroke severity (NIHSS score of ≥6). RESULTS Among 235 study patients, the median age was 64 years (IQR 56-75 years), and 125 (53.2%) were women. In multivariable models adjusted for other significant risk factors, 25(OH) D levels in the lowest and second interquartiles were associated with an increased risk of a NIHSS≥6 (with highest 25 (OH) D quartile as reference) with odd ratios (OR) 3.02(95% confidence interval [CI]:1.59-6.34) and 5.85(2.90-11.54). The median DWI infarct volumes for the serum 25(OH) D level quartiles (lowest to highest) were 12.35, 6.55, 2.44, and 1.59 ml. The median DWI infarct volume in the lowest serum 25(OH) D level quartile was larger than that in the other 3 quartiles (P<0.001). The median adjusted DWI infarct volume in the lowest serum 25(OH) D level quartile was statistically significantly larger than that in the other 3 quartiles (P<0.01). CONCLUSION In conclusion, reduced serum 25(OH) D levels in acute ischemic stroke are an early predictor of larger volumes of ischemic tissue and worse neurological deficit (assessed by the NIHSS).

Abstract
Background Rabies is a global fatal infectious viral disease that is characterized by a high mortality after onset of clinical symptoms. Recently, there has been an increase in the incidence of rabies in China. The aim of this study was to investigate the incidence of human rabies and characterize the rabies virus nucleoprotein gene in dogs sampled from Fujian Province, Southeast China from 2002 to 2012. Methods Data pertaining to human rabies cases in Fujian Province during the period from 2002 through 2012 were collected, and the epidemiological profiles were described. The saliva and brain specimens were collected from dogs in Quanzhou, Longyan and Sanming cities of the province, and the rabies virus antigen was determined in the canine saliva specimens using an ELISA assay. Rabies virus RNA was extracted from canine brain specimens, and rabies virus nucleoprotein gene was amplified using a nested RT-PCR assay, followed by sequencing and genotyping. Results A total of 226 human rabies cases were reported in Fujian Province from 2002 to 2012, in which 197 cases were detected in three cities of Quanzhou, Longyan and Sanming. ELISA assay revealed positive rabies virus antigen in six of eight rabid dogs and 165 of 3492 seemingly healthy dogs. The full-length gene fragment of the rabies virus nucleoprotein gene was amplified from the brain specimens of seven rabid dogs and 12 seemingly healthy dogs. Sequence alignment and phylogenetic analysis revealed that these 19 rabies virus nucleoprotein genes all belonged to genotype I, and were classified into three genetic groups. Sequencing analysis showed a 99.7% to 100% intra-group and an 86.4% to 89.3% inter-group homology. Conclusions This study is the first description pertaining to the epidemiological characteristics of human rabies cases and characterization of the rabies virus nucleoprotein gene in dogs in Fujian Province, Southeast China. Our findings may provide valuable knowledge for the development of strategies targeting the prevention and control of rabies.

Abstract
INTRODUCTION The aim of this study was to investigate whether the pedicle of the rectus abdominis flap can be lengthened by resecting the inferior costal cartilage segments or associated muscle when repairing upper body defects. A formula was generated that calculates the expected increase in pedicle length. METHODS Thirty patients underwent computed tomography. The width and thickness of the third to seventh inferior costal cartilage segments as well as the width of the respective intercostal spaces were recorded. Four patients underwent reconstruction of an upper body defect with the relevant flap. RESULTS The expected mean increases in pedicle length were 4.07cm (standard deviation [SD]: 0.31cm) and 4.63cm (SD: 0.54cm) following resection of the left and right sides respectively of the seventh inferior costal cartilage segment, 7.99cm (SD: 0.49cm) and 10.82cm (SD: 0.23cm) following resection of the left and right sides respectively of the sixth and seventh inferior costal cartilage segments while resection of the fourth to seventh inferior costal cartilage segments would equate to increases of 17.48cm (SD: 0.62cm) and 22.05cm (SD: 0.21cm) for the left and right sides respectively. In four patients who required reconstruction, three flaps survived without problems but one flap developed partial necrosis. CONCLUSIONS Resecting inferior costal cartilage segments or associated muscle can lengthen the pedicle of the rectus abdominis flap for reconstruction of defects on the upper chest and neck.

Abstract
Objective: To explore the association of expression of leptin and leptin receptor (LR) with bone metastasis of pulmonary adenocarcinoma. Methods: One hundred and sixteen pulmonary adenocarcinoma patients who had complete clinicopathological data and definite pathological diagnosis in our hospital from January 2008 to January 2010 were selected. They were divided into the metastasis (n= 58) and non-metastasis (control, n=58) groups. The expressions of leptin and LR were identified by immunohistochemistry. The differences between expressions of leptin and LR in primary pulmonary adenocarcinoma tissues and metastasis, and between the groups with and without bone metastasis were analyzed. We also analyzed the correlation of leptin and LR expressed in primary adenocarcinoma and bone metastatic tissues, and the relationship between their expression levels and bone metastasis free survival (BMFS). Results: Among 58 patients of the metastasis group, the cases of high, moderate and low expressions of leptin were 36, 15 and 7, respectively, and the cases of high, moderate and low expressions of LR were 32, 17 and 9, respectively. Among the 58 patients of control group, the cases of high, moderate and low expressions of leptin were 19, 24 and 15, respectively, and those of LR were 17, 16 and 25, respectively. The expressions of leptin and LR in primary pulmonary adenocarcinoma tissues of metastasis group were significantly different from those of the control group (P=0.006, P=0.002, respectively). The expressions of leptin and LR in primary pulmonary adenocarcinoma tissues of the bone metastasis group were also significantly different from those of the non-bone metastasis group (P=0.029, P=0.032, respectively). The high/moderate expression rates of leptin and LR in the bone-metastatic tissues reached 91.4% (32/35) and 88.6% (31/35), respectively. The results showed that the expressions of leptin and LR in primary pulmonary adenocarcinoma tissues were positively related with their expressions in bone metastatic tissue (r = 0.612). The median bone metastasis free survival (BMFS) of the bone metastasis groups with high, moderate and low expressions of leptin were 14, 21 and 47 months, respectively, and the median BMFS of high, moderate and low expressions of LR in the bone metastasis group were 13, 19 and 27 months, respectively. The expressions of leptin and LR in pulmonary adenocarcinoma were significantly associated with BMFS (P<0.001, P=0.006, respectively). Conclusions: The expressions of leptin and LR are significantly up-regulated in primary pulmonary adenocarcinoma tissues and bone metastatic tissues, and are negatively correlated with BMFS. These two molecules may be used as effective predictors of bone metastasis in pulmonary adenocarcinoma.

Abstract
Signal transducer and activator of transcription 3 (STAT3) is known to activate targets associated with invasion, proliferation, and angiogenesis in a wide variety of cancers. The adaptor protein NCK1 is involved in cytoskeletal movement and was identified as a STAT3-associated target in human tumors. However, the underlying molecular mechanism associated with colorectal cancer (CRC) metastasis is not yet completely understood. In this study, we report a novel STAT3 to NCK1 signaling pathway in colorectal cancer (CRC). We investigated the expression of NCK1 and its potential clinical and biological significance in CRC. NCK1 was noticeably up-regulated in human CRC tissues. NCK1 was also significantly associated with serosal invasion, lymph metastasis, and tumor-node-metastasis classification but was inversely correlated with differentiation. Gain-of-function and loss-of-function studies have shown that ectopic expression of NCK1 enhanced metastasis and angiogenesis in CRC cells. By gene expression analyses, we revealed a high co-overexpression of STAT3 and NCK1 in CRC tissues. Ectopic overexpression of STAT3 in CRC cells induced the expression of NCK1, whereas STAT3 knockdown decreased the expression of NCK1. Promoter activation and binding analyses demonstrated that STAT3 promoted the expression of NCK1 via direct action on the NCK1 promoter. The knock down of NCK1 partially reduced the CRC cell metastasis and angiogenesis promoted by STAT3. Additionally, by co-immunoprecipitation assays, we verified that NCK1 interacted with PAK1, which resulted in the activation of the PAK1/ERK pathway. STAT3 induced the transcription of NCK1 and triggered a PAK1/ERK cascade in CRC. These findings suggest a novel STAT3 to NCK1 to PAK1/ERK signaling mechanism that is potentially critical for CRC metastasis and angiogenesis.

Abstract
OBJECTIVE To investigate the prevalence of hypertension in ocean seamen and major influencing factors, as well as the association between hypertension and serum microRNA21 and microRNA133a. METHODS Health examination and a questionnaire survey were performed for 780 ocean seamen who underwent physical examination in an international travel healthcare center in Fujian, China from January to June, 2014. TaqMan RT-qPCR was used to measure the serum levels of microRNA21 and microRNA133a in seamen with hypertension. RESULTS The prevalence of hypertension differed significantly between the ocean seamen with different ages, education levels, marital status, body mass index (BMI) values, drinking frequencies, and numbers of sailing years (P<0.05). The prevalence rate of hypertension in the ocean seamen increased with the increasing drinking frequency (χ(2)=9.02, P<0.05) , decreased with the increase in degree of education (χ(2)=11.578, P<0.05) , and increased with the increase in the number of sailing years (χ(2)=28.06, P<0.05). The hypertensive ocean seamen had significantly higher expression levels of microRNA21 and MicroRNA133a than the healthy ocean seamen (microRNA21: 7.87±5.46 vs 1.03±0.80, P<0.05; MicroRNA133a: 7.45±1.94 vs 4.52±1.15, P<0.05). The multivariate analysis showed that a high level of microRNA21 (OR=1.61, 95% CI: 1.22~2.11) , a high level of microRNA133a (OR=1.52, 95% CI: 1.24~1.87) , drinking (OR=1.64, 95% CI: 1.08~2.50) , overweight based on BMI (OR=1.18, 95%CI: 1.07~1.30) , and many sailing years (OR=2.89, 95% CI: 1.14~7.30) were risk factors for hypertension. CONCLUSION The prevention and treatment of hypertension in ocean seamen should be enhanced. Excessive drinking should be controlled, and sailing time should be arranged reasonably. The microRNA21 and microRNA133a may be associated with the development and progression of hypertension in ocean seamen.

Abstract
Objective: To investigate the effect of optical zone diameter on corneal biomechanical properties after small incision lenticule extraction (SMILE). Methods: In this prospective case-control study, 62 eyes of 42 patients with myopia and myopic astigmatism that had undergone SMILE procedure were divided into 2 groups according to the optical zone (OZ) diameter: group A, 31 eyes of 19 patients, OZ= 6.5 mm; group B, 31eyes of 23 patients, OZ=6.0 mm. These patients were examined for corneal hysteresis (CH) and corneal resistance factor (CRF) with the Ocular Response Analyzer (ORA) preoperatively and at 1 week, 1 month and 3 months postoperatively; at the same time, the central corneal thickness-corrected indices of DifCH and DifCRF were calculated. Pearson correlation was applied to analyze the correlation between CH and CRF and central corneal thickness. Independent-samples t test was utilized to compare CH and CRF between the two groups. Repeated ANOVA was used to compare the difference of corneal biomechanical properties at different follow-up timepoints. Results: The preoperative mean CRF and CH values were (10.13±1.19) mmHg and (9.65±1.12) mmHg in group A and (10.34±0.89) mmHg and (10.04± 1.05) mmHg in group B, respectively, and no significant differences were found in CRF and CH between the two groups (CRF: t=-0.807, P=0.423. CH: t=-1.405, P=0.165). The mean CRF values in group A at postoperative 1 week and 3 months were (6.62 ± 1.09) mmHg and (6.83 ± 1.07) mmHg, respectively, which were significantly lower than the relevant mean CRF values in group B (t=-2.703, P=0.009. t=-3.733, P= 0.001). Meanwhile, the mean CH values at 1 week, 1 month and 3 months postoperatively in group A were (7.31±1.06) mmHg, (7.37±0.96) mmHg and (7.82±0.97) mmHg, respectively, which were significantly lower than those in group B (t=-2.415, P=0.019. t=-2.113, P=0.039. t=-2.67, P=0.01). Moreover, the DifCRF and DifCH values in group A were significantly lower than those in group B at 3 months postoperatively (t=-3.409, P=0.001. t=-2.064, P=0.044). The CRF and CH values in both groups showed a significant reduction at 1 week, 1 month and 3 months postoperatively (P<0.05). Conclusions: The size of optical zone has some effects on corneal biomechanical properties after SMILE. The smaller optical zone diameter has a relatively smaller effect.
