Abstract
Gastric cancer is one of the most common malignant tumors in the world. In China, its morbidity and mortality are second only to lung cancer. Chemotherapy combined with targeted therapy brings survival benefits to patients with advanced gastric cancer. Targets for targeted therapy of gastric cancer include human epidermal growth factor receptor (EGFR), human epidermal growth factor receptor 2 (HER2), vascular endothelial growth factor (VEGF), mammalian target of rapamycin (mTOR) and Claudin 18.2 (CLDN 18.2). The main challenge of tumor molecule-targeted drugs is resistance. The main mechanisms of drug resistance include tumor establishment of compensatory signaling pathways, target protein changes, tumor microenvironment changes, tumor heterogeneity and tumor adaptation to targeted drugs. The combined action of multiple drug resistance mechanisms promotes the development of targeted drug resistance. In order to attract the attention of researchers, this paper reviews the mechanisms of drug resistance in gastric cancer-targeted therapy. In addition, the research status of drug resistance in molecule-targeted therapy of gastric cancer is summarized. It is of great clinical significance to explore the drug resistance mechanisms of targeted drugs and reverse drug resistance in gastric cancer. Last, the future development of molecule-targeted therapy is prospected.

Abstract
PURPOSE The tumor immune microenvironment (TIME) is now considered as an important factor during gastric cancer (GC) development. This study identified a novel immune-related risk model for predicting prognosis and assessing the immune status of GC patients. METHODS Transcriptomic data were obtained from the TCGA database. The differential expressed immune-related genes (IRGs) were identified through the ImmPort portal. Enrichment analysis was performed to explore the potential molecular mechanism of these IRGs. By the Cox regression analysis, we constructed the immune prognostic model. Then, the association between the model and the immune microenvironment was estimated. The model was validated in the GSE84433 dataset. RESULTS Totally, we identified 222 differentially expressed IRGs. These IRGs were closely correlated with immune response and immune signaling pathways. Through the Cox regression analysis, we developed the immune prognostic model based on the expression of seven IRGs (CXCL3, NOX4, PROC, FAM19A4, RNASE2, IGHD2-15, CGB5). Patients were stratified into two groups according to immune-related risk scores. Survival analysis indicated that the prognosis of high-risk patients was poorer than low-risk patients. Moreover, the immune-related risk score was an independent prognostic biomarker. More importantly, we found that the infiltration level of immunosuppressive cells and the expression of inhibitory immune checkpoints were higher in high-risk patients. The immune microenvironment tended to be a suppressive status in patients with high-risk scores. CONCLUSION This study demonstrated that our model had predictive value for prognosis and the TIME in GC. It might be a robust tool to improve personalized patient management.

Abstract
Alloys that have high strengths at high temperatures are crucial for a variety of important industries including aerospace. Alloys with ordered superlattice structures are attractive for this purpose but generally suffer from poor ductility and rapid grain coarsening. We discovered that nanoscale disordered interfaces can effectively overcome these problems. Interfacial disordering is driven by multielement cosegregation that creates a distinctive nanolayer between adjacent micrometer-scale superlattice grains. This nanolayer acts as a sustainable ductilizing source, which prevents brittle intergranular fractures by enhancing dislocation mobilities. Our superlattice materials have ultrahigh strengths of 1.6 gigapascals with tensile ductilities of 25% at ambient temperature. Simultaneously, we achieved negligible grain coarsening with exceptional softening resistance at elevated temperatures. Designing similar nanolayers may open a pathway for further optimization of alloy properties.

Abstract
AIMS To examine the factor structure, validity and reliability of the Hypoglycemic Attitudes and Behavior Scale (HABS) in T1D adults (previously examined only in T2D adults), and to determine if it has unique value, after controlling for hypoglycemic fear. METHODS The original 14 HABS items were submitted to a confirmatory factor analysis (CFA) with T1D participants. Construct validity criteria included diabetes distress, generalized anxiety, well-being, hypoglycemic fear, hypoglycemia history and self-reported glycemic control. RESULTS A CFA yielded a similar 3-factor solution, with all items loading on the same factors as in the analyses with T2D adults: Hypoglycemia Anxiety, Avoidance and Confidence. Higher levels of Anxiety and Avoidance were significantly associated with poorer well-being and higher levels of generalized anxiety, diabetes distress and hypoglycemic fear, with correlations in the reverse direction for Confidence. After controls (including hypoglycemic fear), the HABS subscales were significantly linked to several criterion variables. CONCLUSIONS Though originally developed and validated with T2D adults, the HABS demonstrates sufficient validity and reliability for use with a T1D population; and it captures unique critical elements of hypoglycemic concerns. Thus, it may contribute to a greater understanding of hypoglycemia management and more targeted clinical interventions in a T1D population.

Abstract
As a newly epidemic, 2019 coronavirus disease (COVID-19) with a concentrated outbreak poses a great challenge to medical treatment. The severe and critical patients are complex complicatied with the psychological problems, and the medical staff are overworked and under tremendous psychological pressure. The surgeon participated in emergency medical rescue could provide professional treatment for the patients combined with surgical diseases, as well as specialized training for the non-surgeon crew, to reduce surgical-related mortality. With the advantages of good team consciousness, strong aseptic concept and good psychological quality, the surgeons can quickly adapt to and carry out rescue work under the premise of good self-protection. Surgeons need to develop critical care management concepts and focus on the critical care support equipment. Some suggestions are put forward for the standardized training of resident surgeons to cultivate compound talents. It is hoped that this article can lead to the thinking of how to participate in the emergency medical rescue of infectious diseases among surgeons and provide some enlightenment for future surgical education.

Abstract
Objective: To Analyze the prenatal factors and forecast the success rate of vaginal delivery of twin pregnancy. Methods: Totally, 114 cases of twin pregnant women who were under the systematic antenatal care and had deliveries in Beijing Obstetrics and Gynecology Hospital from January 2017 to March 2019 were collected. The inclusive criteria were uncomplicated twin pregnancy with head downward position of the first fetus, not monochorioallantoic twin twins, and the willingness for vaginal delivery. Two groups were classified based on their successful vaginal delivery. 96 cases in vaginal delivery group (study group) and 18 cases in the comparison groupwhich were transferred to Caesarean sections during trial delivery. The evaluated prenatal factors included: (1) Fetal factors: the chorionicity of the twin pregnancy, position of the second fetus, fetal weights and the weight difference of two fetuses. (2) Maternal factors:the maternal age, delivery gestational age, parity, body mass index (BMI), reasonability of weight gain during pregnancy, pregnancy complications, such as gestational diabetes mellitus (GDM), hypertensive disorder of pregnancy, and the application of assisted reproductive technology. (3) The technical title of the delivery doctor, modes of labour (spontaneous labor or induced labour and its mode) and the application of labor analgesia, etc. Single-factor logistic analysis and multiple-factor logistic regression were used to do statistical analysis and nomograms were plotted, finally receiver operating characteristic (ROC) curves and standard curves were formed for internal verifications and Youden index were utilized to determine the cut-off values. Results: Five variables:maternal age,complicated GDM, reasonability of weight gain during pregnancy, parity, and the weight of the second fetus is less than the firsthad obvious influence on the success rate of vaginal delivery in twin pregnancy. After quantifying the influence weight, the influence of each factor was as follows:the age of the mother <35 years old: 64; no GDM: 100, no insulin application in GDM: 47, and application of insulin: 0; reasonability of weight gain during pregnancy: 82; parity≥2: 58; and the weight of the second fetus was less than the first: 57. The ROC curve was plotted and the area under the curve (AUC) is 0.856 1, which were able to forecast the success rates well, the maximum value of the Youden index was 0.564 7 and the corresponding score was 168. Conclusions: maternal age, reasonability of weight gain during pregnancy, the complication of GDM, parity, and the weight of the second fetus less than the first are the influential prenatal factors on vaginal delivery of twin pregnancy. After assigning the influence weight of each influencing factor, when the total score reaches 168 the success rate of vaginal delivery is significantly improved.

Abstract
In summer 2018, central and northern Europe were stricken by extreme drought and heat (DH2018). The DH2018 differed from previous events in being preceded by extreme spring warming and brightening, but moderate rainfall deficits, yet registering the fastest transition between wet winter conditions and extreme summer drought. Using 11 vegetation models, we show that spring conditions promoted increased vegetation growth, which, in turn, contributed to fast soil moisture depletion, amplifying the summer drought. We find regional asymmetries in summer ecosystem carbon fluxes: increased (reduced) sink in the northern (southern) areas affected by drought. These asymmetries can be explained by distinct legacy effects of spring growth and of water-use efficiency dynamics mediated by vegetation composition, rather than by distinct ecosystem responses to summer heat/drought. The asymmetries in carbon and water exchanges during spring and summer 2018 suggest that future land-management strategies could influence patterns of summer heat waves and droughts under long-term warming.

Abstract
Risk characterisation of dietary exposure of aflatoxins (AFs), fumonisins (FBs), deoxynivalenol (DON), zearalenone (ZEA) in maize from Shandong Province was conducted in this study. A total of 520 maize samples were collected after harvesting in 2014 and 2015 from 26 selected villages in Shandong Province, China. A deterministic approach was used in the current study. The dietary intake data of maize was obtained from ‘Shandong Statistical Yearbook 2018’. The risk characterisation of FBs, DON, and ZEA was evaluated in 4 population groups (2 to 6-year-old children, standard adults, city adults and village adults) based on probable intake. 2 to 6-year-old children and adults were exposed to FBs (0.42 and 0.20 μg/kg body weight (bw)/day), DON (0.04 and 0.019 μg/kg bw/day), and ZEA (0.0024 and 0.0011 μg/kg bw/day) through mean maize consumption in diets, which was lower than the provisional maximum tolerable daily intake of each mycotoxin established by JECFA. Risk assessments showed a low risk for liver cancer due to consumption of aflatoxin B1 (0.027-0.21 cases per 100,000 persons per year) contaminated maize compared with China’s current liver cancer incidence of 24.6 cases per 100,000 persons per year.

Abstract
Objective:To evaluate the level of melatonin and the role of melatonin in the metastasis of papillary thyroid carcinoma in patients with papillary thyroid carcinoma. Method:We measured serum melatonin levels in 81 patients with papillary thyroid carcinoma(PTC) ,20 patients with multinodular goiter(MNG) and 20 healthy adults using ELISA. The relationship between melatonin and clinicopathological features of PTC were analyzed.The expression of MT1 and MT2 in two subtypes of melatonin receptor in 81 cases of papillary thyroid carcinoma and adjacent tissues were detected by immunohistochemical SP method, and its the mean optical density(MOD) image was analyzed by Image Pro Plusversion(IPP) image processing software. Result:Serum melatonin concentration in patients with PTC was significantly higher than that in MNG patients and normal controls(P<0.05). The level of melatonin in the primary tumor T≥2 cm group was significantly higher than that in the T<2 cm group. Patients with positive cervical lymph nodes(N≥1) had significantly higher melatonin levels than lymph node negatives(N=0)(P<0.05). The MT1 and MT2 receptors were expressed in both PTC and paracancerous tissues, mainly in the cell membrane and cytoplasm. The expression of MT1 receptor was low in the two groups, and there was no statistical difference. The expression of MT2 receptor in PTC tissues Significantly higher than the adjacent tissues(P<0.05), further studies showed that the expression of MT2 receptor in PTC tissues was associated with cervical lymph node metastasis, and the expression of MT2 receptor in PTC tissues with cervical lymph node metastasis was significantly lower than that without metastasis (P<0.05). Conclusion:Serum melatonin levels in PTC patients were higher than those in MNG and control groups, which may be associated with low malignancy of PTC; melatonin inhibits PTC metastasis, which exerts anti-PTC metastasis mainly through MT2 receptors.

Abstract
OBJECTIVES Sarcopenia is an age-related geriatric syndrome and is associated with numerous adverse outcomes. Although there is preponderance of studies on sarcopenia in community setting, few studies focused on the oldest old. We investigated the prevalence of sarcopenia in Chinese community-dwelling oldest old and examined the socio-demographic and lifestyle factors of sarcopenia. We also investigated the association between sarcopenia and disability in activities of daily living (ADL) and physical function among the oldest old. DESIGN Cross-sectional study. SETTING Urban community in Beijing, China. PARTICIPANTS 664 community-dwelling older adults aged 80 years or older. METHODS The presence of sarcopenia and the relationship between sarcopenia and physical function and disability were examined in 582 adults aged 80 years and older. we used the backward stepwise logistic regression model to explore socio-demographic and lifestyle correlates of sarcopenia. Sarcopenia was assessed by an algorithm recommended by the Asian Working Group for Sarcopenia (AWGS). RESULTS The overall prevalence of sarcopenia was 26.6% (female 21.7%; male 33.3%). Age (odds ratio [OR] = 1.14, 95% confidence interval [CI]: 1.06 - 1.22), body mass index (OR = 0.80, 95% CI: 0.73 - 0.89), and Mini-nutritional assessment (MNA) scores (OR = 0.78, 95% CI: 0.64 - 0.96) were independently associated with sarcopenia. The Odds of disability in ADL was approximately two times greater in oldest old with sarcopenia than those without. Sarcopenia was associated with poor lower extremity strength. Oldest old with sarcopenia have higher odds to reported difficulty in stooping, kneeing, or crouching, carrying weights over 5 kilograms, and walking 400 meters. CONCLUSION AND IMPLICATIONS We found over a quartile of the community-dwelling oldest old in China had sarcopenia. Older age, lower BMI, and worse nutritional status were significantly associated with the presence of sarcopenia. Sarcopenia was independently associated with disability and poor physical function.

Abstract
Pancreatic cancer (PC) is a complex and multifactorial human malignancy with a low survival rate. Tumor protein D52 (TPD52) was abnormally expressed in several cancers and participated in tumorigenesis. However, the oncogenic effect of TPD52 on PC remains unknown. In the present study, after transfecting AsPC-1 and PANC-1 cells with NC or sh-TPD52, the CCK-8 assay, Hoechst staining, western blot, transwell assay, flow cytometry were used to examine the cell proliferation, migration, invasion and apoptosis. qRT-PCR results confirmed that the expression of TPD52 was significantly increased in PC cells, especially AsPC-1 and PANC-1 cells. The present study revealed that silencing of TPD52 significantly suppressed the proliferation, migration and invasion, but induced apoptosis of AsPC-1 and PANC-1 cells in vitro by dephosphorylating Akt at Ser473. Conversely, SC79, an Akt activator, could partially reverse the anti-metastatic effects of sh-TPD52, accompanied by the reactivating of Akt pathway. Additional in vivo studies are warranted to elucidate that knockdown of TPD52 could inhibit tumor growth in PC mice models. These findings suggested that TPD52 might be a novel therapeutic target for PC treatment.

Abstract
This study was conducted to determine the effects of residual superdoses of phytase on growth performance, tibia mineralization, and relative organ weight in ducks fed phosphorus-deficient diets. In Exp. 1, 4 kinds of commercial phytase were used to determine retention rate of phyatse with the phytase C being the highest via both high water-bath temperature (90%) and pelleting (50%), followed by phytase A, B, and D. In Exp. 2, a total of 560 male ducks were blocked based on body weight, and then allocated randomly to 7 treatments (5 replicates with 16 birds per replicate). Treatments included a maize-soybean meal-based diet with recommended calcium and 4.0 g non-phytate phosphorus (nPP)/kg starter diet or 3.8 g nPP/kg grower diet (positive control; PC), an nPP-deficient diet with 1.3 g nPP/kg starter diet or 1.1 g nPP/kg grower diet (negative control; NC), NC diets with increasing levels of residual phytase C (500, 1,000, 2,000, 3,000, and 4,000 units/kg feed) after pelleting. Birds fed NC diets had lower (P < 0.05) average daily gain (ADG) and average daily feed intake (ADFI) throughout the experiment compared with those fed PC diet. Supplementing NC diet with increasing residual superdoses of phytase improved (P < 0.05) ADG and ADFI quadratically in the entire experiment, while reduced feed-to-gain ratio (P < 0.05) quadratically during day 0 to 14. On day 14 and 35, birds fed NC diet had lower (P < 0.05) tibia length, weight, ash, calcium, phosphorus, and manganese contents than those fed PC diet. Increasing residual superdoses of phytase in NC diet increased (P < 0.05) tibia weight and ash, calcium, phosphorus contents quadratically on day 14 and 35. NC treatment increased (P < 0.05) the duodenum, jejunum, ileum, and cecum index compared with other treatments on day 14 and 35. Taken together, feeding increasing residual superdoses of phytase could counteract or exceed the negative effects of NC diet on growth performance, tibia mineralization, and relative organ weight in ducks.

Abstract
The 2'-substituents distinguish DNA from RNA nucleosides. 2'-O-methylation occurs naturally in RNA and plays important roles in biological processes. Such 2'-modifications may alter the hydrogen-bonding interactions of the nucleoside and thus may affect the conformations of the nucleoside in an RNA chain. Structures of the protonated 2'-O-methylated pyrimidine nucleosides were examined by infrared multiple photon dissociation (IRMPD) action spectroscopy, assisted by electronic structure calculations. The glycosidic bond stabilities of the protonated 2'-O-methylated pyrimidine nucleosides, [Nuom+H]+, were also examined and compared to their DNA and RNA nucleoside analogues via energy-resolved collision-induced dissociation (ER-CID). The preferred sites of protonation of the 2'-O-methylated pyrimidine nucleosides parallel their canonical DNA and RNA nucleoside analogues, [dNuo+H]+ and [Nuo+H]+, yet their nucleobase orientation and sugar puckering differ. The glycosidic bond stabilities of the protonated pyrimidine nucleosides follow the order: [dNuo+H]+ < [Nuo+H]+ < [Nuom+H]+. The slightly altered structures help explain the stabilization induced by 2'-O-methylation of the pyrimidine nucleosides.

Abstract
OBJECTIVE To explore the correlations of endothelial nitric oxide synthase (eNOS) G894T and endothelin-2 (ET-2) A985G gene polymorphisms with eclampsia. PATIENTS AND METHODS A total of 110 eclampsia patients in our hospital from July 2014 to August 2017 were enrolled as the observation group and 100 healthy pregnant women in the same period as the control group. The polymorphisms of eNOS G894T and ET-2 A985G genes in the two groups were analyzed via polymerase chain reaction (PCR), and their correlations with eclampsia risk were investigated. RESULTS The distribution frequency of eNOS G894T genotype TT and GT and T allele, as well as the ET-2 A985G genotype GG and AG and G allele, were evidently higher in the observation group than in the control group (p<0.05). ENOS G894T genotype TT and ET-2 A985G genotype GG were significantly associated with the occurrence of eclampsia. CONCLUSIONS The polymorphisms of eNOS G894T and ET-2 A985G genes are correlated with the occurrence of eclampsia.

Abstract
Objective: To analyze the incidence and influencing factors of venous thromboembolism (VTE) after lung transplantation. Methods: This study retrospectively analyzed the clinical data of 375 lung transplant patients from January 2015 to December 2017 in Wuxi People's Hospital. Every patient was classified into the VTE group or the non-VTE group according to whether the patient had VTE or not. Basic information like age, type of surgical procedure etc. was compared between two groups. The prevention and treatment of VTE between two groups were also compared. Furthermore, multivariate Logistic regression analysis was used to analyze the influence of related factors on the occurrence of postoperative VTE. Deep venous thrombosis (DVT) was diagnosed with vascular ultrasonography, and pulmonary thromboembolism (PTE) was diagnosed with CT pulmonary angiogram, nuclear ventilation/perfusion scanning, or pulmonary angiography. Results: This study included 316 lung transplant patients. VTE occurred in 19 patients (6.0%) during perioperative and follow-up period. The age of the VTE group was significantly higher than that of the non-VTE group (63.4±11.9 vs 54.3±13.0, P=0.003). The proportion of single lung transplantation in the VTE group was significantly higher than that in the non-VTE group (78.9% vs 48.5%, P=0.010). The incidence of VTE in patients without prevention was significantly higher than that in patients with prevention (15.0% vs 1.9%, P<0.001). Single lung transplantation (OR=4.425, P=0.018), duration in intensive care unit (ICU) (OR=1.396, P=0.001) and age (OR=1.080, P=0.005) were independent risk factors for VTE after lung transplantation. Conclusions: The incidence of VTE after lung transplantation is high. Single lung transplantation, prolonged duration of ICU stay and advanced age increase the risk of VTE after lung transplantation.

Abstract
Objective: To investigate whether high-dose methylprednisolone with Rituximab and fresh frozen plasma (HDMP+RTX+FFP) is an effective therapy for patients with B-cell chronic lymphoproliferative disorders (B-CLPD) with TP53 abnormalities. Methods: Six B-CLPD patients with TP53 abnormalities from May 2008 to May 2012 were prospectively enrolled in the study. The patients were treated with HDMP+RTX+FFP for up to 6 cycles. Results: Of the six B-CLPD patients, there were 4 cases of chronic B-cell lymphoproliferative disorders-unclassified (B-CLPD-U) , 1 B-cell prolymphocytic leukemia (B-PLL) and 1 mantle cell lymphoma (MCL) . After a median 3 courses of treatment, 4 patients achieved complete remission (CR) including 3 with undetectable minimal residual disease (MRD(-)) . One patient was evaluated as stable disease (SD) and another one patient was in disease progression (PD) . After a median follow-up of 30 (4-56) months, 2 non-responders progressed quickly and died. All of CR patients survived and no one succumbed to disease progression at the last follow-up. The hematopoietic function was significantly improved after the treatment whereas there was also significant decrease in serum IgA, IgG and IgM levels. All patients showed well tolerance to this regimen. The incidence of myelosuppression was low and adverse events (AE) were mainly neutropenia which did not exceed grade 3 and infection. All AE were controllable. Conclusion: HDMP+RTX+FFP is an effective and relatively tolerable therapy for patients with B-CLPD accompanying with TP53 abnormalities.

Abstract
Objective: To study the effect of p-phenylenediamine (PPD) on liver and kidney function in occupational exposed workers. Methods: Workers in a hair dye production enterprise which used p-phenylenediamine as a raw material for production were selected as the main research population. Then we conducted a questionnaire survey on the basic conditions of workers and conducted occupational health checkups on general health status, liver and kidney function. Occupational health examination assessment results were tested in Taizhou Cancer Hospital. All data was built using EpiData 3.1 software, and statistical analysis was performed using software SPSS 20.0. Results: The liver function indicators including direct bilirubin, prealbumin, total protein, and white protein, globulin, aspartate aminotransferase, glutamyl transpeptidase, and total bilirubin in the workers exposed to high concentration of PPD were at high normal values, and these indicators were significantly different from low PPD concentration group (P<0.05) . The serum creatinine and serum uric acid in the renal function index were significantly higher in workers exposed to PPD than in workers exposed to low concentrations and in the control group (P<0.05) . Conclusion: Occupational exposed to PPD may have a hazard to the workers' liver and kidney function. Long-term occupational exposure to PPD may lead to increased cumulative exposure of workers, which may cause potential chronic liver and kidney damage in occupationally exposed populations.

Abstract
Fine Particulate Matter (PM(2.5)-particles with an aerodynamic diameter ≤2.5 μm) can penetrate deeply into the lung, deposit in the alveoli, and consequently impair lung function. Both short term and long term exposures to PM(2.5) are associated with the incidence of respiratory diseases (e.g. asthma, chronic obstructive pulmonary disease, lung cancer). This paper summarizes the effects of ambient air PM(2.5) exposure on human respiratory system revealed by epidemiological studies.

Abstract
目的 探究淋巴细胞/单核细胞比值(LMR)在血管免疫母细胞性T细胞淋巴瘤(AITL)患者中的预后价值。 方法 回顾性分析2009年6月至2017年7月南京医科大学第一附属医院收治的64例初诊AITL患者资料。采用ROC曲线计算LMR临界值,并以此将患者分为高LMR和低LMR组,采用Pearson卡方检验及Fisher精确概率法进行组间比较。采用Kaplan-Meier法和Cox回归分析影响无进展生存(PFS)和总生存(OS)的预后因素。 结果 64例患者中,男39例,女25例,中位年龄63(29~89)岁。LMR临界值为3.07。中位随访33(5~103)个月,低LMR与高LMR组比较,患者的PFS时间(9对13个月,P=0.044)和OS时间(16个月对未达到,P=0.014)差异均有统计学意义。多因素分析显示低LMR是影响患者PFS(HR=0.48, 95% CI 0.26~0.92,P=0.027)和OS(HR=0.38,95% CI 0.18~0.82,P=0.013)的独立预后不良因素。亚组分析结果显示,在中高危至高危[非特指型预后指数(PIT)评分2~4分]患者中,低LMR者有更短的PFS和OS时间(P值分别为0.013、0.031),而在低危至中低危(PIT评分0~1分)患者中其差异均无统计学意义(P值分别为0.949、0.238)。 结论 可根据PIT评分及LMR的状态初步评估患者的疾病风险。低LMR提示患者具有更差的预后。

Abstract
Objective: To evaluate the risk factors and sonographic findings of pregnancies complicated by placenta increta or placenta percreta. Methods: Totally, 2 219 cases were retrospectively analyzed from 20 tertiary hospitals in China from January 2011 to December 2015. The data were collected based on the original case records. All cases were divided into two groups, the placenta increta (PI) group (79.1%, 1 755/2 219) and the placenta percreta (PP) group (20.9%, 464/2 219) , according to the degree of placental implantation. The risk factors and sonographic findings of placenta increta or percreta were analyzed by uni-factor and logistic regression statistic methods. Results: The risk factors associated with the degree of placental implantation were age, gravida, previous abortion or miscarriage, previous cesarean sections, and placenta previa (all P<0.05), especially, previous cesarean sections (χ(2)=157.961) and placenta previa (χ(2)=91.759). Sonographic findings could be used to predict the degree of placental invasion especially the boundaries between placenta and uterine serosa, the boundary between placenta and myometrium, the disruption of the placental-uterine wall interface and loss of the normal retroplacental hypoechoic zone(all P<0.01). Conclusions: Previous cesarean sections and placenta previa are the main independent risk factors associated with the degree of placenta implantation. Ultrasound could be used to make a prenatal suggestive diagnosis of placenta accreta spectrum disorders.

Abstract
OBJECTIVE This study aimed to evaluate the expression characteristics of lamin A/C proteins in intervertebral disc degeneration (IVD) specimens from patients with different degeneration grades. Lamin A/C proteins have been shown to result in age-related changes in the osteoarticular system. However, the expression characteristics of these nuclear proteins in degenerated human IVD tissues have not been explored previously. PATIENTS AND METHODS Degenerated human IVD tissues were obtained during spinal surgery. Articular cartilage samples after total knee replacement surgery were used as controls. Sections of these tissues were stained with hematoxylin and eosin, Masson, safranin O, and immunostained using lamin A/C antibody. Western blot was performed to evaluate lamin A/C expression in IVD tissues. Lamin A/C expression was analyzed based on different degeneration grades. RESULTS In patients with IVD degeneration, mild or moderate degenerative discs contained high amounts of lamin A/C proteins. Lamin A/C expression was primarily localized in the nuclear envelope of IVD cells, and associated with apoptosis in cell nuclei, as determined by immunostaining and TUNEL assay. CONCLUSIONS This paper is the first to report that lamin A/C proteins are present in IVD tissues and its expression may be related to disc degeneration.

Abstract
Objective: To investigate the prevalence of iron deficiency (ID) and iron deficiency anemia (IDA) in pregnant women in urban areas of China. Methods: The study was a national cross-sectional survey conducted from September 19th, 2016 to November 20th, 2016. According to the classification of the National Bureau of Statistics, all survey sites were set up in 6 regions of the country.Pregnant women were continuously selected using multistage stratified sampling. A total of 12 403 pregnant women were collected and examined for serum ferritin and hemoglobin levels. Results: The median serum ferritin level during pregnancy was 20.60 μg/L (11.78-36.98 μg/L) , the hemoglobin level was (118±12) g/L. With the progress of pregnancy, the levels of serum ferritin and hemoglobin decreased gradually. The median serum ferritin levels in the first, second trimester and third trimester were 54.30 μg/L (34.48-94.01 μg/L) , 28.60 μg/L (16.40-50.52 μg/L) , and 16.70 μg/L (10.20-27.00 μg/L) respectively (P<0.01) . The mean hemoglobin levels were (127±10) g/L, (119±11) g/L and (117±11) g/L respectively (P<0.01) . The prevalence of ID in urban pregnant women was 48.16% (5 973/12 403) , and IDA prevalence was 13.87% (1 720/12 403) . The prevalence of IDA in the first, second trimester and third trimester were 1.96% (20/1 019) , 8.40% (293/3 487) and 17.82% (1 407/7 897) ,respectively (P<0.01) . The prevalence of standardized ID and IDA were significantly different in various regions of China (P<0.01) . The standardized prevalence of ID were relatively higher in East China and Northeast China, 57.37% and 53.41% respectively, while it was the lowest in Southwest China, 30.51%. The standardized prevalence of IDA in South Central, Northwest, and East China were relatively high, 21.30%, 16.97% and 17.53% respectively, and the standardized prevalence of IDA in Southwest China was the lowest, 5.44%, the differents in various regions were significant (all P<0.01) . Conclusion: The current phenomenon of ID and IDA in pregnant women is still very common, and nutrition and health care during pregnancy should be strengthened.

Abstract
Objective: To investigate the effects of ethylbenzene on growth morphology、proliferation ability and mitochondrial membrane potential (MMP) of cochlear progenitor cells (CPCs) , and to lay a foundation for the mechanism of hearing loss induced by ethylbenzene. Methods: We can use the fluorescence microscopy to identify the original CPCs isolated from the newborn rats, and followed by the addition of different concentrations of ethylbenzene (0, 15, 30, 45 μmol/L) for 24 hours. The morphological changes of cell injury were observed by inverted optical microscope. The proliferation ability of cells was detected by MTT colorimetry, and the change of MMP was detected by fluorescent probe JC-1. Results: The results of CPCs identification showed the expression of Myosin VIIa and Epsin positive; The results observed by inverted optical microscope showed all groups of CPCs morphological changes compared with the control group; MTT results showed that the decreased significantly proliferation ability of CPCs groups compared with the control group and a dose effect relationship with statistically significant difference (P<0.05) ; JC-1 test results showed the decreased significantly mitochondrial membrane potential in the treated group compared with the control group, and there was a statistically significant difference (P<0.05) . Conclusion: Ethylbenzene may cause damage to CPCs, inhibition of cell proliferation and decrease of MMP in rats.
