Abstract
The human body is in a complex environment affected by body heat, light, and sweat, requiring the development of a wearable multifunctional textile for human utilization. Meanwhile, the traditional thermoelectric yarn is limited by expensive and scarce inorganic thermoelectric materials, which restricts the development of thermoelectric textiles. Therefore, in this paper, photothermoelectric yarns (PPDA-PPy-PEDOT/CuI) using organic poly(3,4-ethylenedioxythiophene) (PEDOT) and inorganic thermoelectric material cuprous iodide (CuI) are used for the thermoelectric layer and poly(pyrrole) (PPy) for the light-absorbing layer. With the introduction of PPy, the temperature difference of the photothermoelectric yarn can be increased for a better voltage output. Subsequently synergizing the photothermoelectric effect with the hydrovoltaic effect to create higher electric potentials, a single wet photothermoelectric yarn obtained by preparation can be irradiated under an infrared lamp at a voltage of up to 0.47 V. Finally, the photothermoelectric yarn PPDA-PPy-PEDOT/CuI was assembled in a series and parallel to obtain a photothermoelectric yarn panel, which was able to output 41.19 mV under an infrared lamp, and the synergistic photothermoelectric and hydrovoltaic effects of the photothermoelectric panel were tested outdoors on human body, and we found that the voltage was able to reach approximately 0.16 V under sunlight. Therefore, the voltage values obtained from the photothermoelectric yarns in this study are competitive and provide a new research idea for the study of photothermoelectric yarns.

Abstract
BACKGROUND Prenatal bisphenol exposure has been reported to be associated with lower birth weight and obesity-related indicators in early childhood. These findings warrant an investigation of the relationship between prenatal bisphenol exposure and the dynamic growth of offspring. This study aimed to evaluate the relationship of maternal bisphenol concentration in urine with the body mass index (BMI) growth trajectory of children aged up to two years and to identify the critical exposure periods. METHODS A total of 826 mother-offspring pairs were recruited from Wuhan Children's Hospital between November 2013 and March 2015. Maternal urine samples collected during the first, second, and third trimesters were analyzed for bisphenol A (BPA), bisphenol S, and bisphenol F (BPF) concentrations. Measurements of length and weight were taken at 0, 1, 3, 6, 8, 12, 18, and 24 months. Children's BMI was standardized using the World Health Organization reference, and group-based trajectory modeling was used to identify BMI growth trajectories. The associations between prenatal bisphenol exposure and BMI growth trajectory patterns were assessed using multinomial logistic regression models. RESULTS The BMI growth trajectories of the 826 children were categorized into four patterns: low-stable (n = 134, 16.2%), low-increasing (n = 142, 17.2%), moderate-stable (n = 350, 42.4%), and moderate-increasing (n = 200, 24.2%). After adjusting for potential confounders, we observed that prenatal exposure to BPA during the second trimester [odds ratio (OR) = 2.20, 95% confidence interval (CI) = 1.09-4.43] and BPF during the third trimester (OR = 3.28, 95% CI = 1.55-6.95) at the highest quartile concentration were associated with an increased likelihood of the low-increasing BMI trajectory. Furthermore, in the subgroup analysis by infant sex, the positive association between the highest quartile of prenatal average urinary BPF concentration during the whole pregnancy and the low-increasing BMI trajectory was found only in girls (OR = 2.82, 95% CI = 1.04-7.68). CONCLUSION Our study findings suggest that prenatal exposure to BPA and BPF (a commonly used substitute for BPA) is associated with BMI growth trajectories in offspring during the first two years, increasing the likelihood of the low-increasing pattern.

Abstract
Objective: To examine the safety and effectiveness of thin struct bare stents for the treatment of spontaneous isolated dissection of the superior mesenteric artery (SIDSMA). Methods: The data of 32 patients admitted to First Hospital of Jiaxing (20 cases) and Jinling Hospital (12 cases) with SIDSMA from January 2016 to January 2021 were retrospectively analyzed. There were 27 males and 5 females, aging (54.8±9.4) years (range: 36 to 75 years). All patients were treated with thin struct bare stents. Controllable spring coils were used to fulfill the false lumen in 2 cases. Symptoms, vascular remodeling pattern at the SIDSMA lesion, and patency of the stents were observed during follow-up. Results: The surgical success rate was 100%. According to the length of the lesions and stents, the number of stents implanted was 1 in 17 cases, 2 in 11 cases and 3 in 4 cases. The angiography showed that blood flow in the stent was smooth and that the false lumen disappeared or weakened. The numerical rating scale for abdominal pain decreased from 6.1±1.5 (range: 4 to 10) preoperatively to 1.0 (1.0) (range: 0 to 3) 1 hour postoperatively (W=528, P<0.01). The compression rate of the true lumen of the superior mesenteric artery decreased from (92.3±6.7)% (range: 25% to 94%) preoperatively to 0.8 (1.2)% (range: 0 to 3.2%) 1 month postoperatively (W=528, P<0.01). The primary patency rate of CT angiography at 1 month postoperatively was 100%. The vascular remodeling rate was (92.3±6.7)% (range: 80% to 100%). All patients were followed for (46.3±17.0) months (range: 24 to 76 months). The cumulative patency rates in 1, 2 and 5 years were all 100%. Conclusion: The use of thin struct bare stents for SIDSMA is safety and efficacy.

Abstract
Arbuscular mycorrhizal fungi (AMF) can form symbiosis with Elaeagnus angustifolia, allowing this species to tolerate salt stress. However, the physiological mechanism through which AMF improve E. angustifolia tolerance is still unclear. In this study, we examined E. angustifolia inoculated with AMF Rhizophagus irregularis (M) or inactivated inoculum (NM) under 0 and 300 mM NaCl stress for the determination of photosynthetic gas exchange, pigment content, chlorophyll fluorescence, antioxidant capacity and chloroplast ultrastructural in leaves. Photosynthetic gas exchange parameters in the leaves of M and NM decreased significantly under salt stress, while the M treatment significantly reduced the effect of salt stress compared with NM. Various chlorophyll components in the M treatment were two- to three-fold higher than in NM, together with a much more complex chloroplast structure and higher number of plastoglobules. The total flavonoid and proline content in leaves of M increased significantly, while the concentration of malondialdehyde (MDA) decreased significantly under salt stress. Chlorophyll fluorescence data also showed good PSII function in the M treatment, together with salt stress reduction of photochemical reactions and sharp enhancements in non-photosynthetic quenching (NPQ). AMF inoculation ameliorated the inhibition on the actual PSII efficiency (ФPSII) and the photochemical quenching coefficient (qP ) by 10-15%. Our results clearly demonstrate that R. irregularis can improve the salt tolerance of plants by improving leaf photosynthetic performance, PSII function, antioxidant capacity and leaf chloroplast ultrastructure, and that E. angustifolia inoculated with AMF could enhance saline soil rehabilitation.

Abstract
Objective: To examine the relative factors of transmural intestinal necrosis (TIN) during multidisciplinary stepwise management facilitating the decision making in patients with acute superior mesenteric vein thrombosis (ASMVT). Methods: Clinical data of patients with ASMVT admitted to Department of General Surgery, Jinling Hospital from January 2009 to June 2017 were reviewed retrospectively. There were 52 males and 37 females, aging (45.9 ± 12.6) years (range: 20 to 69 years). According to the postoperative pathological results and follow-up, the patients were divided into TIN group (n=31) and non-TIN group (n=58, including 18 cases of intestinal stricture). The related factors were compared between ASMVT patients with TIN and patients without TIN by univariate analysis using t test, U test and χ(2) test accordingly, and factors with statistically significance were subsequently submitted to binary Logistic regression analysis. The predictive value and cut-off point of factors were evaluated by receiver operator characteristic (ROC) curve and area under the curve. Results: In univariate analysis, smoking, hypertension, peritonitis, white blood cell count,haemoglobin, international normalized ratio, blood albumin, thrombosis of superior mesenteric branches vein, free intraperitoneal fluid, decrease of bowel wall enhancement and pneumatosis intestinalis were TIN risk factors (all P<0.05). According to the binary Logistic regression analysis, white blood cell count (OR=1.093, 95%CI: 1.010 to 1.182, P=0.027), thrombosis of the superior mesenteric branches vein (OR=11.519, 95%CI: 1.906 to 69.615, P=0.008), pneumatosis intestinalis (OR=11.140, 95%CI: 2.360 to 52.585, P=0.002) were independent relative factors of TIN in patients with AMI, and the area under the ROC curve of the above factors and predictive model was 0.759 (95%CI: 0.647 to 0.871), 0.745 (95%CI: 0.641 to 0.848), 0.737 (95%CI: 0.621 to 0.854), 0.909 (95%CI: 0.847 to 0.971), respectively. The cutoff value of white blood cell count was 18.1 × 10(9)/L. Conclusion: White blood cell levels, superior mesenteric vein branch thrombosis and pneumatosis intestinalis are independent predictors of TIN in ASMVT.

Abstract
Microglia play an essential role during cerebral an ischemia/reperfusion (I/R)-related inflammatory process. Because the M2 phenotype of microglia exhibits anti-inflammation activity, it has become a promising target for anti-inflammatory therapy. Vagus nerve stimulation (VNS) reportedly has neuroprotective effects against cerebral I/R injuries via its anti-inflammatory action. The aim of this study was to investigate the ability of non-invasive VNS (nVNS) to alleviate cerebral I/R in mice by promoting microglial M2 polarization. Neurological scoring and cerebral infarct volume assessments were performed 72 h after a middle cerebral artery occlusion (MCAO)-induced stroke. M2 phenotype microglia were identified by immunohistochemistry staining using Arg-1 and Iba-1 antibodies. The protein expressions of Arg-1, IL-17A, IL-10, Bax, and Bcl-2 were detected by Western blot. Apoptotic cells were detected using TUNEL staining. According to our results, nVNS decreased infarct volume, improved neurological outcomes, reduced apoptotic neurons (TUNEL+NeuN+ cells), and promoted microglial M2 polarization as indicated by elevated Arg-1 protein expression and increased Arg-1+ cells after MCAO. Moreover, nVNS attenuated the increased levels of IL-17A protein expression after MCAO. To test the possible involvement of IL-17A in nVNS-induced neuroprotection and microglial M2 polarization, 1-μg recombinant IL-17A (rIL-17A) was intranasally administered once daily for three consecutive days after reperfusion. We found that the intranasal administration of rIL-17A nullified the nVNS-induced promotion of microglial M2 polarization. Furthermore, rIL-17A administration abolished the neuroprotective effect of nVNS. In conclusion, our study identifies microglial M2 polarization as an important mechanism underlying the nVNS-mediated neuroprotection against cerebral I/R. This effect of nVNS could be attributed to the inhibition of IL-17A expression.

Abstract
Reticulons (RTNs) are a family of membrane-bound proteins that are dominantly localized to the endoplasmic reticulum (ER) membrane. RTN1-C is one member of RTNs abundantly expressed in the brain and has been shown to mediate neuronal injury in cerebral ischemia models. In the present study, we investigated the role of RTN1-C in an in vitro brain trauma model mimicked by traumatic neuronal injury (TNI) in primary cultured cortical neurons. TNI increased the expression of RTN1-C in cortical neurons but had no effect on RTN1-A and RTN1-B. Knockdown of RTN1-C with specific siRNA (Si-RTN1-C) significantly decreased cytotoxicity and apoptosis after TNI. The results of Ca2+ imaging showed that intracellular Ca2+ overload induced by TNI was attenuated by RTN1-C knockdown. Furthermore, the activation of metabotropic glutamate receptor 1 (mGluR1)-induced Ca2+ response was partially prevented by Si-RTN1-C transfection. We also evaluated the role of RTN1-C in store-operated Ca2+ entry (SOCE) in cortical neurons using the ER Ca2+ inducer thapsigargin (Tg). The results showed that knockdown of RTN1-C alleviated the SOCE-mediated Ca2+ influx and decreased the expression of stromal interactive molecule 1 (STIM1). In summary, the present study found that knockdown of RTN1-C protected neurons against TNI via preservation of intracellular Ca2+ homeostasis, which was associated with the inhibition of mGluR1-mediated ER Ca2+ release and suppression of STIM1-related SOCE. Thus, RTN1-C might represent a therapeutic target for traumatic brain injury (TBI) research.

Objective: To evaluate the safety and flexibility of uncut Roux-en-Y esophagojejunostomy in totally laparoscopic total gastrectomy (TLTG). Methods: Between July 2016 to November 2016, 15 patients received totally laparoscopic total gastrectomy plus uncut Roux-en-Y esophagojejunostomy in the Sir Run Run Shaw hospital. Clinical data of those patients, including operative indexes, post-operative indexes and fellow-up data, were analyzed respectively. Results: A total of 15 patients were enrolled in this study, ten were corpus carcinoma and five were esophagogastric junction carcinoma. The total operative time and anastomosis time was (25.0±4.3) min and (25.0±4.3) min, the blood loss during operation was (133.3±121.2) ml. All the operations were performed successfully, and no one was transferred to open surgery. All the patients were encouraged to off-bed activity at first day after surgery. The first time to flatus, the first time to liquid food intake and the length of stay in hospital were (4.1±0.8) days, (5.1±0.9) days and (9.3±1.6) days, respectively. The pathological staging of these patients was stage Ⅰb in 1 case, stage Ⅱa in 3 cases, stageⅡb in 2 cases, stage Ⅲb in 3 cases, stage Ⅲc in 6 cases. The lymph node harvest was (36.0±12.3). Cutting margins in all patients were negative. Pulmonary infection occurred in one patient postoperatively and recovered after antibiotic treatment. No death and severe complication was found. Liver metastasis occurred in one patient eight months after operation. One patient was found recurrence in anastomotic site. No Roux-en-Y stasis syndrome was found. Conclusions: Uncut Roux-en-Y esophagojejunostomy in TLTG is safe and flexible.

Abstract
Objective: To investigate the effects and the underlying mechanism of DS2, a newly synthetic analog of natural ent-kaurane diterpenoid, on the proliferation and migration capabilities of human gastric cancer cells. Methods: MTT assay, colony formation assay and flow cytometry were used to measure the effects of DS2 on growth, apoptosis and cell cycle of several human gastric cancer cell lines. The function of DS2 in the migration was further detected by wound healing and transwell assays. The expression of migration related proteins were determined by western blot. Results: DS2 inhibited the growth of MGC-803, SGC-7901 and HGC-27 cells in a dose dependent manner. After treatment of DS2 at a concentration of 6.25 μmol/L for 24 h, the survival rates of MGC-803, SGC-7901 and HGC-27 cells were 53.87±3.05%, 55.91±6.97% and 32.41±2.64%, respectively. However, for the normal gastric epithelial cell GES-1, no obvious growth inhibition was observed. In addition, DS2 caused significant G(2)/M arrest and induced apoptosis in MGC-803 cells. Furthermore, compared with the negative control, the colony formation, wound healing rate as well as the number of migrating cells of MGC-803 were significantly decreased in a dose dependent manner after DS2 treatment. DS2 induced the expression of E-cadherin, whereas β-catenin and N-cadherin levels were downregulated in MGC-803. Conclusion: The new compound DS2 has a strong anti-cancer activity, and this study will help us to design and synthesize better diterpenoids derivatives.

Abstract
Objective: To investigate the effect of transcatheter arterial chemoembolization(TACE)combined with thymosin alpha1(Tα1)on the autophagy of immune cells from advanced hepatocellular carcinoma. Methods: A total of 30 patients with advanced liver cancer enrolled in Lishui Central Hospital from September 2015 to June 2016 were collected in this study. The average age of patients was 16-75(56±12) years. All patients were treated with TACE after enrolled in hospital in a week. Patients were divided into TACE group and TACE+ Tα1 treatment group(15 cases in each group). Patients in TACE group received a conventional treatment, without any immunotherapy, while the TACE+ Tα1 treatment group accepted TACE following a subcutaneously injection of 1.6 mg Tα1 twice a week for 4 weeks. Flow cytometry was used to detect the T cell subsets in two groups both before and after TACE treatment for 1, 4 weeks and at 3 months follow-up. Peripheral blood mononuclear cells (PBMC) were isolated by density gradient centrifugation. The expression of Beclin-1, LC3 protein and mRNA were detected by Western blot (WB) and PCR respectively. Results: There was no statistical difference of the percentage of CD3(+) , CD4(+) , CD8(+) T cell subsets and Beclin-1, LC3 protein and mRNA expression between the two groups before TACE treatment (P>0.05). The percentage of CD3(+) , CD4(+) , CD8(+) T cell subsets in TACE+ Tα1 group at 1 week post-TACE treatment (58.45%±16.34%, 38.33%±15.16%, 27.31%±12.54%), at 4 weeks post-TACE treatment (62.38%±18.62%, 43.19%±13.86%, 29.54%±10.33%) and 3 months follow-up (64.15%±13.76%, 41.28%±14.65%, 29.38%±15.65%) were statistically higher than those in TACE group at 1 week post-TACE treatment (53.71%±11.17%, 32.12%±10.53%, 24.45%±13.72%) at 4 weeks post-TACE treatment (52.12%±14.26%, 31.16%±15.43%, 23.39%±15.33%) and 3 months follow-up (54.28%±13.15%, 32.17%±14.98%, 24.34%±14.12%) (P<0.05). The Beclin-1, LC3 protein and mRNA expression in TACE+ Tα1 group at 1 week post-TACE treatment (protein: 0.57±0.08, 2.26±0.36, mRNA: 0.62±0.11, 2.69±0.27), at 4 weeks post-TACE treatment (protein: 0.66±0.09, 3.11±0.45, mRNA: 0.78±0.13, 3.43±0.61) were higher than those in TACE group at 1 week post-TACE treatment (protein: 0.45±0.16, 1.43±0.30, mRNA: 0.52±0.15, 1.15±0.37), at 4 weeks post-TACE treatment (protein: 0.51±0.13, 1.81±0.35, mRNA: 0.56±0.10, 1.98±0.41) ( P<0.05). But there was no statistically significant difference in the expression of Beclin-1 and LC3 in two groups at 3 months follow-up (P>0.05). Conclusions: TACE combined with Tα1 significantly increase the level of autophagy in the immune cells of patients with advanced primary hepatocellular carcinoma.

Abstract
Objective: To evaluate the application value of carbon lymph node tracing technique by preoperative endoscopic subserosal injection in laparoscopic radical gastrectomy. Methods: From June 2013 to February 2015, seventy eight patients with gastric cancer were enrolled and randomly divided into trial group and control group. Subserosal injection of carbon nanoparticles around the tumor was performed by preoperative endoscopic subserosal injection one day before the operation in trial group, while the patients routinely underwent laparoscopic gastrectomy in control group. Results of harvested lymph nodes, postoperative complications were compared between the two groups. Carbon nanoparticle-related side effect was also evaluated. Results: The average number of harvested lymph node in trial group was significantly higher than that in control group (35.5±8.5 vs 29.5±6.5, P<0.05). The rate of overall black-dyed harvested lymph node was 74.7% (1 035/1 386) in trial group, the black-dyed lymph node rate in D1 lymph node was 80.1%, which was significantly higher than that in D2 lymph node (69.8%, χ2=19.38, P<0.01). When comparing the lymph node with and without black-dyed in trial group, the rate of metastasis lymph node was significantly higher in lymph node with black-dyed (17.3% vs 4.0%, χ2=38.67, P<0.01). There was no significant difference in postoperative complications rate between two group (trial group 10.2%; control group 12.8%, χ2=0.00, P>0.05), and no carbon nanoparticle-related side effect was observed. Conclusion: Given a higher harvested lymph node number and a similar rate of complications, preoperative endoscopic subserosal injection of carbon nanoparticles was safe and feasible.

Abstract
Objective: To discuss the association between ultrasound screening frequency and total mortality in patients with HCC before diagnosing HCC, and explore the optimal ultrasound screening frequency for HCC high-risk groups. Methods: Retrospectively collected clinical data of 615 cases of liver cirrhosis who developed to HCC from January 1, 2010 to December 31, 2015. Before diagnosing HCC, all patients were divided into five groups according to ultrasound screening frequency: 0-6, 7-12, 13-24, 25-36 months and not screened within 3 years (never screened). The chance to receive curative therapy, 5-year cumulative mortalities and independent factors of mortality in patients with HCC were analyzed. Results: Chances to receive curative therapy among the 0-6, 7-12, 13-24, 25-36 months and never screened groups were 38.2%, 27.2%, 25.4%, 23.8% and 19.7%, respectively (P<0.05). The 5-year overall mortality rates were 76.4%, 77.7%, 79.3%, 82.5% and 84.6%, respectively. Compared with 0-6 months, the adjusted OR of mortality for the other groups were 1.112, 1.235, 1.305 and 1.451, respectively (all P<0.05). Multivariate analysis showed that ultrasound screening frequency, curative treatment and Child-Pugh (class A/B) were the factors to affect long-term survival in patients with HCC (all P<0.05). Conclusion: For HCC high-risk groups, optimal ultrasound screening frequency is within 6 months, and high-frequency ultrasound screening can increase the chance of receiving curative treatment, reduce total mortality, and improve overall survival.

Abstract
To uncover the molecular mechanisms underlying the intestinal barrier integrity, this study determined whether the rapamycin (RAPA)-sensitive target of rapamycin complex 1 (TORC1) pathway was involved in this process. Three groups of 4-day-old male chicks were randomly subjected to one of the following treatments for 6 days: high-dose RAPA [a specific inhibitor of TORC1; an intraperitoneal injection of 1.0 mg/kg body weight (BW), once daily at 09:00 hours], low-dose RAPA (0.4 mg/kg BW) and RAPA vehicle (control). Results showed that the RAPA treatment increased mortality, while decreasing villus height (p < 0.01), claudin 1 expression, content of immunoglobulin A (IgA), extent of TORC1 phosphorylation (p < 0.05), ratio of villus height to crypt depth (p < 0.01), and population of IgA-positive B cells in intestinal mucosa, particularly for the jejunum. Some aspects of these responses were dose dependent and appeared to result from weight loss. Together, RAPA exerts the expected inhibition of small intestinal development and IgA production in birds, suggesting the important role of TORC1 in gut barrier integrity.
