Abstract
Objective: To assess the levels of serum glycocalyx markers in the first 24 hours after cardiac arrest (CA) and investigate their relationship with 30-day outcomes. Methods: A retrospective cohort study was conducted on prospectively collected data from CA patients, who were admitted to the intensive care units of the Affiliated Hospital of Xuzhou Medical University and obtained return of spontaneous circulation for more than 24 hours between September 2021 and October 2022. Serum samples obtained at the 24-hour after CA were utilized to measure the levels of glycocalyx markers, including heparan sulfate (HS), hyaluronic acid (HA), and syndecan-1 (Sdc-1). Patients were allocated into good function (CPC1-2) and poor function (CPC3-5) groups on the basis of cerebral performance category (CPC) at 30 days post-CA. Logistic regression analysis was used to determine the association between serum glycocalyx markers and neurological outcomes. Patients were regrouped in light of 30-d mortality and Cox regression analysis was used to determine the association between serum glycocalyx markers and 30-d mortality. Results: A total of 71 patients were included in the study, including 31 (43.7%) females and 40 (56.3%) males, with an average age of (59.0±17.0) years. The poor function group (n=49) demonstrated significantly elevated levels of HS and HA when compared to the good function group (n=22) [HS: 2 461.0(1 623.0, 5 492.0) μg/L vs 1 492.0 (914.0, 2 550.0) μg/L, P=0.008; HA: 124.0(97.0, 365.0)μg/L vs 337.0(135.0, 1 421.0) μg/L, P=0.033]. Adjusted logistic regression analysis revealed that HS was independently associated with poor neurological outcome [odds ratio (OR)=0.389, 95% confidence interval (CI): 0.182-0.828, P=0.014]. In the 30-day mortality analysis, the death group (n=32) exhibited significantly higher levels of HS and HA when compared to the survival group (n=39) [HS: 1 880.0(1 011.0, 3 554.0) μg/L vs 2 500.0(1 726.0, 6 276.0) μg/L, P=0.027; HA: 162.0(99.0, 537.0) μg/L vs 813.0(148.0, 1 531.0) μg/L, P=0.025]. Adjusted Cox regression analysis indicated that elevated levels of HS and HA were independent risk factors (HS: HR=1.697, 95%CI: 1.126-2.557, P=0.011; HA: HR=1.336, 95%CI: 1.047-1.705, P=0.020) for 30-day mortality. Conclusions: High level of serum HS in 24 hours after CA may serve as a potential predictive marker for both neurological function and 30-day mortality. However, high level of serum HA appears to primarily predict 30-day mortality. Sdc-1 does not seem to contribute to outcome prediction.

Abstract
Vascular fibrosis is a widespread pathologic condition that arises during vascular remodeling in cardiovascular dysfunctions. According to previous studies, vascular fibrosis is characterized by endothelial matrix deposition and vascular wall thickening. The RAAS and TGF-β/Smad signaling pathways have been frequently highlighted. It is, however, far from explicit in terms of understanding the cause and progression of vascular fibrosis. In this review, we collected and categorized a large number of molecules which influence the fibrosing process, in order to acquire a better understanding of vascular fibrosis, particularly of pathologic dysfunction. Furthermore, several mediators that prevent vascular fibrosis are discussed in depth in this review, with the aim that this will contribute to the future prevention and treatment of related conditions.

Abstract
In clinical trials, rhubarb extract (Rb) was demonstrated to efficiently alleviate constipation. We would like to find out the underlying mechanism of rhubarb relieving constipation. However, there are few studies on the effects of rhubarb on colonic mucus secretion and constipation. The aim of this study was to investigate the effects of rhubarb on colonic mucus secretion and its underlying mechanism. The mice were randomly divided into four groups. Group I was the control group and Group II was the rhubarb control group, with Rb (24 g/kg body weight [b.w.]) administered through intragastric administration for three days. Group III mice were given diphenoxylate (20 mg/kg b.w.) for five days via gavage to induce constipation. Group IV received diphenoxylate lasting five days before undergoing Rb administration for three days. The condition of the colon was evaluated using an endoscope. Particularly, the diameter of blood vessels in the colonic mucosa expanded considerably in constipation mice along with diminishing mucus output, which was in line with the observation via scanning electron microscope (SEM) and transmission electron microscope (TEM). We also performed metagenomic analysis to reveal the microbiome related to mucin gene expression level referring to mucin secretion. In conclusion, Rb relieves constipation by rebuilding mucus homeostasis and regulating the microbiome.

Abstract
Strong shocks are essential components in many high-energy-density environments such as inertial confinement fusion implosions. However, the experimental measurements of the spatial structures of such shocks are sparse. In this paper, the soft x-ray emission of a shock front in a helium gas mixture (90% helium, 10% neon) and a pure neon gas was spatially resolved using an imaging spectrometer. We observe that the shock width in the helium mixture gas is about twice as large as in the pure neon gas. Moreover, they exhibit different precursor layers, where electron temperature greatly exceeds ion temperature, extending for more than ∼350µm with the helium gas mixture but less than 30µm in the pure neon. At the shock front, calculations show that the electrons are strongly collisional with mean-free path two orders of magnitude shorter than the characteristic length of the shock. However, the helium ions can reach a kinetic regime as a consequence of their mean-free path being comparable to the scale of the shock. A radiation-hydrodynamic simulation demonstrates the impact of thermal conduction on the formation of the precursors with charge state, Z, playing a major role in heat flow and the precursor formation in both the helium mixture and the pure neon gases. Particle-in-cell simulations are also performed to study the ion kinetic effects on the formation of the observed precursors. A group of fast-streaming ions is observed leading the shock only in the helium gas mixture. Both effects explain the longer precursor layer in the helium shock.

Abstract
(1) Background: Depression is the most prevalent psychiatric symptom present among individuals of all ages and backgrounds, impacting an estimated 300 million people globally. Therefore, it demands a significant amount of attention when it comes to managing depression. A growing amount of data reveal that probiotics and fatty acids could be beneficial to depression. However, the opposing position maintains that they have no influence on depression. A network meta-analyses of existing datasets aid in the estimation of comparative efficacy as well as in achieving an understanding of the relative merits of different therapies. The purpose of this study was to investigate the current evidence for probiotic or fatty acid depression therapy and to establish a practical alternative for depression patients using a meta-analysis and metagenomic data from a Wistar-Kyoto (WKY) depressed rat model. (2) Methods: Probiotic data were obtained from seven randomized controlled trial studies (n = 394), and fatty acid data were obtained from 24 randomized controlled trial studies (n = 1876). Meanwhile, a metagenomics analysis of data on animal gut flora was also applied to validate the preceding evidence. (3) Results: The fatty acid studies were separated into three sections based on the duration of probiotic delivery: ≤8 weeks, 9-12 weeks, and >12 weeks. The results were as follows: for ≤8 weeks, MD = -1.65 (95% CI: -2.96--0.15), p = 0.01; for 9-12 weeks, MD = -2.22 (95% CI: -3.03--1.22), p < 0.001; for >12 weeks, MD = -1.23 (95% CI: -2.85-0.39), p = 0.14. Regarding the probiotics, the meta-analysis revealed MD = -2.19 (95% CI: -3.38--2.43), p < 0.001. The research presented herein illustrates that probiotics and fatty acids may successfully lower depression scores. Additionally, the probiotics were drastically reduced in the WKY rats. (4) Conclusions: According to the data, a depression intervention utilizing probiotics outperformed the control, implying that the use of probiotics and fatty acids may be a successful strategy for depression treatment.

Abstract
Background Glioma is one of the most malignant and aggressive tumors, with an extremely poor prognosis. Human telomerase reverse transcriptase (hTERT) promoter mutation is regarded as a risk factor in tumor growth. Although the prevalence of hTERT promoter (pTERT) mutation in gliomas has been investigated, the results are inconsistent. This meta-analysis aims to investigate the prognostic value of hTERT in glioma patients and its interaction with other biomarkers. Materials and Methods We searched 244 citations from four databases: PubMed (2000-2021), Web of Science (2000-2021), Embase (2010-2021), and Cochrane Library (2000-2021) with 28 articles included. Results We calculated hazard ratios (HRs) using the random effect model and the pooled result suggested that TERT promoter mutation predicted poorer overall survival (HR: 1.53, 95% confidence interval [CI]: 1.34-1.75, P < 0.001, I2: 49.9%, pheterogeneity:0.002) and progression-free survival (HR: 1.55, 95% CI: 1.27-1.88, P < 0.001, I2: 0.0%, pheterogeneity: 0.473). For subgroup analysis, we analyzed multiple factors including iso-citrate dehydrogenase (IDH) genotype, age, diagnosis, pTERT region, so as to locate the sources of heterogeneity. Interestingly, in IDH mutant subgroup, pTERT mutation became a beneficial prognostic factor (HR: 0.73, 95% CI: 0.57-0.93, I2: 22.3%, pheterogeneity: 0.277), which is contrary to the results in pooled analysis. Conclusion In general, pTERT mutation may result in shorter survival time in glioma patients, but longer survival time when glioma patients are combined with IDH mutation.

Abstract
Background: Constipation is a common syndrome and a worldwide healthy problem. Constipation patients are becoming younger, with a 29.6% overall prevalence in children, which has captured significant attention because of its epigenetic rejuvenation and recurrent episodes. Despite the usage of rhubarb extract to relieve constipation, novel targets and genes implicated in target-relevant pathways with remarkable functionalities should still be sought for. Materials and methods: We established a reliable constipation model in C57B/6N male mice using intragastric administration diphenoxylate, and the eligible subjects received 600 mg/25 g rhubarb extract to alleviate constipation. Resultant constipation was morphological and genetically compared with the specimen from different groups. Results: Constipation mice exhibited thicker muscle layers, higher levels of cytokines, including IL-17 and IL-23, and lower content of IL-22. Bacterial abundance and diversity varied tremendously. Notably, the alterations were reversed following rhubarb extract treatment. Additionally, Constipation also had a substantial impact on short-chain fatty acids (SCFAs), medium- and long-chain fatty acids (MLCFAs), and the expression of SCFA receptors, GPR41 and GPR43. Conclusion: This thesis has provided insight that rhubarb extract promoted the flexibility of collagen fiber, reduced pro-inflammatory cytokines, enhanced anti-inflammatory cytokines, and maintained gut microflora balance with potential impacts on the fatty acid and polyamine metabolism.

Abstract
The gut microbiota is the most abundant and diverse microbiota in the human body and the vagus nerve is the most widely distributed and complex nerve in the body, both of them are essential in maintaining homeostasis. The most important phenomenon is how they coordinate to regulate functions, which has attracted the great attention of scientists. The academic literature on the correlation with a host of intestinal diseases and even systemic diseases has revealed the bidirectional communication between the gut microbiota and the brain, which can be carried out via multiple patterns. In the review, firstly, we have a general overview of the gut microbiota and the gut microbiota-brain axis. Secondly, according to the distribution characteristics of the vagus nerve, we analyzed and summarized its function in the intestinal tract. At the same time, we have summarized the underlying mechanism of some behavior changes such as depressive and anxiety-like behaviors and related neurodegenerative diseases caused by the vagus nerve and intestinal microecological environment disorders, and then we also analyzed inconsistency of the experimental evidence in order to propose novel strategies for the clinical practice.

Abstract
With the development of psychology and medicine, more and more diseases have found their psychological origins and associations, especially ulceration and other mucosal injuries, within the digestive system. However, the association of psychological factors with lesions of the oral mucosa, including oral squamous cell carcinoma (OSCC), burning mouth syndrome (BMS), and recurrent aphthous stomatitis (RAS), have not been fully characterized. In this review, after introducing the association between psychological and nervous factors and diseases, we provide detailed descriptions of the psychology and nerve fibers involved in the pathology of OSCC, BMS, and RAS, pointing out the underlying mechanisms and suggesting the clinical indications.

Abstract
The endoplasmic reticulum, a vast reticular membranous network from the nuclear envelope to the plasma membrane responsible for the synthesis, maturation, and trafficking of a wide range of proteins, is considerably sensitive to changes in its luminal homeostasis. The loss of ER luminal homeostasis leads to abnormalities referred to as endoplasmic reticulum (ER) stress. Thus, the cell activates an adaptive response known as the unfolded protein response (UPR), a mechanism to stabilize ER homeostasis under severe environmental conditions. ER stress has recently been postulated as a disease research breakthrough due to its significant role in multiple vital cellular functions. This has caused numerous reports that ER stress-induced cell dysfunction has been implicated as an essential contributor to the occurrence and development of many diseases, resulting in them targeting the relief of ER stress. This review aims to outline the multiple molecular mechanisms of ER stress that can elucidate ER as an expansive, membrane-enclosed organelle playing a crucial role in numerous cellular functions with evident changes of several cells encountering ER stress. Alongside, we mainly focused on the therapeutic potential of ER stress inhibition in gastrointestinal diseases such as inflammatory bowel disease (IBD) and colorectal cancer. To conclude, we reviewed advanced research and highlighted future treatment strategies of ER stress-associated conditions.

Abstract
Abstract
In this study,90Sr was used as the test radionuclide to characterize the sorption kinetics and effects of initial 90Sr activity and remaining 90Sr in solid concentration were simulated for a near-surface repository. The study focused on the sorption characteristics of radionuclides in unsaturated groundwater environment (or vadose zone) is the important information for investigating the near-surface disposal of intermediate and low-level radioactive waste (ILLW). Moreover, the 90Sr sorption experiments reached equilibrium within 56 h, which fit to the first order sorption kinetic model, and the remaining 90Sr in mudrock samples showed obvious sorption equilibrium hysteresis, which fit to the second order sorption kinetic model. Before reaching the maximum sorption capacity, the sorption rate constant increases with 90Sr increasing; the distribution coefficient (Kd) of 56 h decreases with the remaining 90Sr decreasing. In addition, it showed that the slow sorption process dominated before the sorption reaches equilibrium. In fact, a reliable safety assessment methodology for on-going near-surface repository required a lot of the radionuclides parameters with local environment including the radionuclides sorption/desorption rate constant and maximum sorption capacity.

Abstract
The 2019-nCoV is a rapidly contagious pneumonia caused by the recently discovered coronavirus. Although generally the most noticeable symptoms are concentrated in the lungs, the disorders in the gastrointestinal tract are of great importance in the diagnosis of 2019-nCoV. The angiotensin-converting enzyme 2 (ACE2), an important regulator of many physiological functions, including blood pressure and nutrients absorption, is recently identified as a vital entry for 2019-nCoV to enter host cells. In this review, we summarize its functions both physiologically and pathologically. We also elaborate its conflicting roles from the clews of contemporary researches, which may provide significant indications for pharmacological investigations and clinical uses.

Abstract
Objectives: To examine the prognosis factors of recurrence of esophageal carcinoma within 6 months after neoadjuvant therapy followd by surgery. Methods: The clinical data of 187 patients with esophageal squamous cell carcinoma who underwent neoadjuvant therapy followed by curative esophagectomy between January 2018 and April 2020 at Department of Thoracic Surgery, Shanghai Chest Hospital were analyzed retrospectively. There were 160 males and 27 females, aging (63.0±7.1) years (range:43 to 76 years). The t test, χ2 test and rank-sum test were used for univariate analysis of the prognosis factors for recurrence within 6 months postoperative, while the Logistic regression was used for multivariate analysis. Results: There were 30 patients (16.0%) developed recurrence within 6 months after operation, including local recurrence in 1 case, regional recurrence in 11 cases, hematogenous recurrence in 13 cases, and combined recurrence in 5 cases. Univariate analysis suggested that there was a significant difference in T staging of tumor before neoadjuvant therapy (cT), tumor regression grade, circumferential resection margin, pathological T stage (ypT) and pathological N stage (ypN) between the recurrence patients and non-recurrence patients (all P<0.05). Logistic regression analysis suggested that the cT3-4 (OR=2.701, 95%CI: 1.161 to 6.329, P=0.021) and ypN(+)(OR=1.654, 95%CI: 1.045 to 2.591, P=0.032) were the independent prognosis factors for recurrence within 6 months. Conclusion: The combination of neoadjuvant therapy and surgery is not effective in reducing early postoperative recurrence in patients who have invaded the epineurium before treatment, and still have positive lymph nodes after neoadjuvant therapy.

Abstract
Purpose Hypertension (HTN) is a major risk factor for cardiovascular disease. In recent years, there were numerous studies on the function of stress in HTN. However, the gut dysbiosis linked to hypertension in animal models under stress is still incompletely understood. Purpose of this study is to use multiple determination method to determine the juvenile stage intestinal bacteria, cytokines and changes in hormone levels. Methods Four groups of juvenile male spontaneously hypertensive rats (SHRs) and age-matched male Wistar-Kyoto (WKY) rats were randomly selected as control and experimental groups. Rats in the two stress groups were exposed to restraint stress for 3 hours per day for 7 consecutive days. In one day three times in the method of non-invasive type tail-cuff monitoring blood pressure. The detailed mechanism was illuminated based on the intestinal change using immunohistochemical and immunofluorescence staining and the stress-related hormone and inflammation factors were analyzed via ELISA method. The integrity of the epithelial barrier was assessed using FITC/HRP and the expression levels of proteins associated with the tight junction was detected by Western blot. The alteration of stress-related intestinal flora from ileocecal junction and distal colon were also analyzed using its 16S rDNA sequencing. Results The results indicate that acute stress rapidly increases mean arterial pressure which is positive correlation to hormone concentration, especially in SHR-stress group. Meanwhile, stress promoted the enhancement of epithelial permeability accompanied with a reduced expression of the tight junction-related protein and the macrophages (Mφ) aggregation to the lamina propria. There were remarkable significant increase of stress-related hormones and pro-inflammatory factor interleukin (IL)-6 along with a decrease in the diversity of intestinal flora and an imbalance in the F/B ratio. Conclusion Our results reveal that stress accompanied with HTN could significantly disrupt the domino effect between intestinal flora and homeostasis.

Abstract
Objective: To examine the preliminary clinical efficacy of Chinese magnetic sphincter augmentation (MSA) in the treatment of gastroesophageal reflux disease (GERD). Methods: According to the enrollment criteria for the MSA developed by ShengJieKang Co. and Shanghai Chest Hospital (SS-MSA) clinical trial, a total of 19 GERD patients were treated with SS-MSA from August 2018 to January 2020 at Department of Thoracic Surgery, Shanghai Chest Hospital, Shanghai Jiao Tong University. The majority of registered cases were male patients with age of (32.2±7.3) years (range: 22 to 50 years), height of (170.7±6.2) cm (range: 160 to 179 cm) and weight of (65.2±10.3) kg (range: 47.5 to 90.0 kg). SS-MSA was implanted via laparoscopy. The major evaluation indexs of postoperative efficacy were the total time of acid exposure within 24 hours and the total number of reflux. Secondary efficacy indicators included: (1) evaluation of the average daily dose of proton pump inhibitor medications; (2) the score of GERD health related quality of life questionnaire (GERD-Q) before and after MSA implantation. Paired design t-test was used to evaluate the efficacy of the SS-MSA. Results: A total of 19 patients underwent SS-MSA surgery successfully. The history of the GERD were 19 (54) months (M(Q(R))). The operation time was 63 (22) minutes and the in-hospital stay was 3 (2) days. No obvious surgical complications occurred. Postoperative adverse events included 14 cases with mild to moderate dysphagia exited after surgery, gradually eased within 1 to 3 months, 1 case with the removal of the device after 1 month of severe swallowing difficulties, 1 case of diarrhea. No corrosion, perforation, displacement occurred. The GERD-Q score (11.0(4.5) vs. 6(1.0), t=4.274, P=0.013), 24-hour acid exposure time (6.2(4.8)% vs. 0.1(0.9)%, t=5.814, P=0.004), and Demeester score (23.72(16.20) vs. 0.96(3.10), t=6.678, P=0.003) were significantly decreased 1 year after surgery(n=5). Proton pump inhibitor reuse rates were 6/18, 5/15, 3/10, and 1/5 in 1, 3, 6 and 12 months after the operation, respectively. Conclusions: SS-MSA implantation is feasible and safe with short hospital stay and rare perioperative complications. The preliminary results is good after 1 year follow-up. It could be expected to be an ideal substitutive for future GERD treatment.

Abstract
Controversy exists on the advantages of robotic McKeown esophagectomy (RME) versus thoraco-laparoscopic McKeown esophagectomy (TLME). The aim was to evaluate the short- and mid-term outcomes of RME and TLME in the treatment of patients with esophageal squamous cell carcinoma (ESCC). A consecutive series of 652 patients, 280 in RME and 372 in TLME, who underwent minimally invasive McKeown esophagectomy for ESCC at our department from November 2015 to June 2018 was analyzed. A propensity score-matched comparison with clinicopathological covariates was performed between the two groups. Complications were categorized based on the Esophagectomy Complications Consensus Group (ECCG) recommendation. To identify the recurrence, all patients with R0 resection were followed with a median follow-up period of 20.2 months (range 1-33 months). After propensity score matching, 271 patients were identified for each cohort. In the matched cohorts, two patients died within 90 days in TLME, whereas no patients died in RME. RME was associated with similar intraoperative blood loss (P = 0.895), but with shorter surgical duration (244.5 vs. 276.0 min, P < 0.001), shorter thoracic duration (85.0 vs. 102.9 min, P < 0.001) and lower thoracic conversions (0.7% vs. 5.9%, P = 0.001). In spite of the similar results on total and thoracic lymph nodes dissection, RME yielded more lymph nodes along recurrent laryngeal nerve (4.8 vs. 4.1, P = 0.012), as well as the higher incidence of recurrent nerve injury (29.2% vs. 15.1%, P < 0.001) when compared to TLME. Tumor recurrence occurred in 30 patients and was locoregional only in 9 (3.5%) patients, systemic only in 17 (6.7%) patients, and combined in 4 (1.6%) patients in RME, while in 26 patients and was locoregional only in 10 (10.6%) patients, systemic only in 7 (2.8%) patients, and combined in 9 (3.6%) patients in TLME. RME was associated with a lower rate of mediastinal lymph nodes recurrence (2.0% vs. 5.3%, P = 0.044). Overall and disease-free survival was not different between the two cohorts (P = 0.097 and P = 0.248, respectively). RME was shown to be a safe and oncologically effective approach with favorable short- and mid-term outcomes in the treatment of patients with ESCC.

Abstract
Shocks are abundant both in astrophysical and laboratory systems. While the electric fields generated at shock fronts have recently attracted great attention, the associated self-generated magnetic field is rarely studied, despite its ability to significantly affect the shock profile in the nonideal geometry where density and temperature gradients are not parallel. We report here the observation of a magnetic field at the front of a Mach ∼6 shock propagating in a low-density helium gas system. Proton radiography from different projection angles not only confirms the magnetic field's existence, but also provides a quantitative measurement of the field strength in the range ∼5 to 7 T. X-ray spectrometry allowed inference of the density and temperature at the shock front, constraining the plasma conditions under which the magnetic and electric fields are generated. Simulations with the particle-in-cell code lsp attribute the self-generation of the magnetic field to the Biermann battery effect (∇n_{e}×∇T_{e}).

Abstract
Our understanding of the dynamics of ion collisional energy loss in a plasma is still not complete, in part due to the difficulty and lack of high-quality experimental measurements. These measurements are crucial to benchmark existing models. Here, we show that such a measurement is possible using high-flux proton beams accelerated by high intensity short pulse lasers, where there is a high number of particles in a picosecond pulse, which is ideal for measurements in quickly expanding plasmas. By reducing the energy bandwidth of the protons using a passive selector, we have made proton stopping measurements in partially ionized Argon and fully ionized Hydrogen plasmas with electron temperatures of hundreds of eV and densities in the range 1020-1021 cm-3. In the first case, we have observed, consistently with previous reports, enhanced stopping of protons when compared to stopping power in non-ionized gas. In the second case, we have observed for the first time the regime of reduced stopping, which is theoretically predicted in such hot and fully ionized plasma. The versatility of these tunable short-pulse laser based ion sources, where the ion type and energy can be changed at will, could open up the possibility for a variety of ion stopping power measurements in plasmas so long as they are well characterized in terms of temperature and density. In turn, these measurements will allow tests of the validity of existing theoretical models.

Abstract
Thermal conductivity is one of the most crucial physical properties of matter when it comes to understanding heat transport, hydrodynamic evolution, and energy balance in systems ranging from astrophysical objects to fusion plasmas. In the warm dense matter regime, experimental data are very scarce so that many theoretical models remain untested. Here we present the first thermal conductivity measurements of aluminum at 0.5–2.7 g/cc and 2–10 eV, using a recently developed platform of differential heating. A temperature gradient is induced in a Au/Al dual-layer target by proton heating, and subsequent heat flow from the hotter Au to the Al rear surface is detected by two simultaneous time-resolved diagnostics. A systematic data set allows for constraining both thermal conductivity and equation-of-state models. Simulations using Purgatorio model or Sesame S27314 for Al thermal conductivity and LEOS for Au/Al release equation-of-state show good agreement with data after 15 ps. Discrepancy still exists at early time 0–15 ps, likely due to non-equilibrium conditions.

Abstract
A proton backlighting platform has been developed for the study of strong shock propagation in low-density systems in planar geometry. Electric fields at the converging shock front in inertial confinement fusion implosions have been previously observed, demonstrating the presence of-and the need to understand-strong electric fields not modeled in standard radiation-hydrodynamic simulations. In this planar configuration, long-pulse ultraviolet lasers are used to drive a strong shock into a gas-cell target, while a short-pulse proton backlighter side-on radiographs the shock propagation. The capabilities of the platform are presented here. Future experiments will vary shock strength and gas fill, to probe shock conditions at different Z and Te.

Abstract
This study aimed to evaluate the influence of plasma exchange (PE) treatment of patients with liver failure on the patient's immune function, including peripheral blood T lymphocytes and cytokines. Patients accepting PE for liver failure from October 2011 to February 2012 were included prospectively in the research group. Peripheral blood samples were collected at set time points. The percentages of T lymphocyte subtypes were detected by flow cytometry using different fluorescence labels including CD3-FITC, CD4-PerCP, CD8-PE, CD25-FITC, and Foxp3-PE. Changes in serum IL-17 concentration were followed by ELISA. In all fifteen patients who accepted PE, the percentages of CD3(+) and CD8(+) T cells increased immediately after the procedure and then reduced gradually. These significant changes were confirmed by statistical analysis (P < 0.05). The percentage of CD4(+) T cells also increased after PE to a certain extent, but failed to show statistical significance. The positive ratio of CD4(+)CD25(+)Foxp3(+) T cells (Treg) increased after the treatment with statistical difference (P < 0.05). The concentration of IL-17 in patient serum increased significantly following PE treatment (P < 0.05). These results demonstrated that T lymphocyte subgroups of patients with liver failure could be influenced after PE treatment, and that cellular immunity could be recovered. PE treatment, therefore, can be viewed as providing reliable protection for the reconstruction of the patient immune system.

Abstract
OBJECTIVE The aim of this study was to improve the understanding of FBA in children and to decrease the rate of misdiagnosis, missed diagnosis and morbidity. PATIENTS AND METHODS We analyzed the clinical features and the three-dimensional reconstructed CT images of 590 children with foreign body aspiration (FBA) in the Xuzhou area of the Jiangsu province. RESULTS CT imaging revealed common complications of FBA including emphysema (n = 379), pneumonia (n = 174), and atelectasis (n = 26). The remaining 120 patients had no visible complications on the three-dimensional reconstructed CT images. Serious complications including pneumothorax, pneumomediastinum, subcutaneous emphysema, pneumatorrhachis could also be observed. The types of foreign bodies were diverse: the most common were peanuts and sunflower seeds. The diagnostic accuracy of the three-dimensional CT imaging was high, with a sensitivity and specificity of 99.83% and 99.89%, respectively. CONCLUSIONS 3D CT imaging is an accurate, non-invasive technique to evaluate children with suspected FBA that can help decrease the rate of misdiagnosis and eliminate a delay in treatment for this potentially life-threatening condition.

Abstract
BACKGROUND Invasion and metastasis are the distinct biologic characteristics of cancer, resulting in an exceptionally low 5-year survival rate in pancreatic ductal adenocarcinoma (PDAC). Understanding in detail the mechanisms underlying PDAC metastasis is critical for prevention and effective interventions. Long non-coding RNAs (lncRNAs) have been documented as having a critical role in cancer development and progression. METHODS We examined the expression levels of lncRNA ENST00000480739 and osteosarcoma amplified-9 (OS-9) mRNA in a cohort of 35 PDAC patients. Cell proliferation, invasion and migration were examined with and without ENST00000480739 overexpression in PDAC cells. RESULTS We determined that the ENST00000480739 expression level was remarkably decreased in tumorous tissues compared with their corresponding non-tumorous tissues. The expression of ENST00000480739 was negatively associated with tumour node metastasis stage and lymph node metastasis. In addition, ENST0000048073 was an independent prognostic factor of survival time in PDAC patients following surgery. Besides, enforced expression of ENST00000480739 suppressed PDAC cells' invasion in vitro. Overexpression of ENST00000480739 significantly increased both mRNA and protein levels of OS-9, and the luciferase assays confirmed that ENST00000480739 positively regulates OS-9 by activating the transcription level of the OS-9 promoter. We further found that ENST00000480739 may target hypoxia-inducible factor-1α (HIF-1α) expression by upregulating OS-9. CONCLUSIONS These findings suggest that the frequently downregulated ENST00000480739 in PDAC contributes to tumour metastasis and progression by regulating HIF-1α. Long non-coding RNA ENST00000480739 may provide not only a therapeutic potential to suppress metastasis but it may also be a novel biomarker for risk prognostication and personal therapy screening of PDAC patients.

Abstract
BACKGROUND Although visceral hypersensitivity is a major pathophysiological feature of irritable bowel syndrome (IBS), its underlying mechanisms remain elusive. Toll-like receptor 4 (TLR4) is a critical pattern recognition molecule of the innate immune system. In this study, we investigated whether the TLR4/myeloid differentiation factor 88 (MyD88)/nuclear factor-kappa B (NF-κB) signalling pathway in the spinal cord contributed to the visceral hypersensitivity induced by neonatal colonic irritation (CI) in rats. METHODS The Sprague-Dawley rat model of IBS was induced by colon irritation on post-natal day (PND) 8, PND10 and PND12. Experiments were conducted in adult rats. TLR4 mRNA and protein, and its downstream signalling molecules, MyD88, inhibitory nuclear factor-kappa B (IκB) and NF-κB protein expressions in L2-S4 spinal segments were detected by quantitative real-time reverse transcription-polymerase chain reaction as well as Western blotting. TLR4 co-localization was determined by immunohistochemistry. Levels of tumour necrosis factor-alpha (TNF-α) and interleukin 1β (IL-1β) were measured with enzyme-linked immunosorbent assay. RESULTS We found that neonatal CI treatment induced long-lasting visceral hypersensitivity without identifiable structural abnormalities in descending colons of adult rats. Neonatal CI treatment evoked a significant up-regulation of the expressions of TLR4 in glia, MyD88, p-IκB-α and NF-κB in adult rats. Neonatal CI treatment also increased the levels of its downstream inflammatory agents TNF-α and IL-1β in the L2-S4 regions of the spinal cord of adult rats. CONCLUSIONS These results suggest that neonatal CI stimulates the production of IL-1β and TNF-α through the TLR4/MyD88/NF-κB signalling pathway in the spinal cord, which contributed to visceral hypersensitivity induced by neonatal CI in rats.

Abstract
BACKGROUND Primary pancreatic lymphoma (PPL) is an extremely rare form of extranodal malignant lymphoma and pancreatic tumour. Natural killer/T-cell lymphoma is an aggressive rare form extranodal lymphoma with a predilection for the nasal cavity/nasopharynx, it can arise in other organs such as skin, testicles, spleen, adrenal, or GI tract, but the initial presentation of our patient in the pancreas is unreported. CASE PRESENTATION We present a case of primary pancreatic natural killer/T-cell nasal type lymphoma in a 62-year-old man. The presenting symptoms were non-specific only for upper abdominal pain and weight loss. Imaging techniques showed the lesion was located in the head of pancreas. Computed tomography (CT) scanning and otorhinolaryngology examination were negative for nasopharyngeal lymphoma. The initial concern was for pancreatic tumor and the patient underwent pancreaticoduodenectomy. The diagnosis of primary pancreatic natural killer/T-cell nasal type lymphoma was established as the combination of NK-lineage antigens (TIA-1, granzyme B, CD56) with EBV-expression. CONCLUSIONS This is the first case of primary pancreatic natural killer (NK)/T-cell nasal type lymphoma. PPL, although a rare pathologic entity, should be considered in the differential diagnosis for a large homogeneous mass with extrapancreatic extension in the head especially in those of normal serum CA 19-9 level.

Abstract
OBJECTIVES A remarkable increase in traumatic spinal cord injury (TSCI) morbidity has occurred in China from 2001 to 2010 due to rapid industrial and economic development; this increase seriously threatens public health. The current study investigated the major causes and severity of TSCI in 561 hospitalized TSCI patients who came from all over China to the General Hospital of Chinese People's Armed Police Forces. METHODS Information (including each patient's age, gender, time and cause of injury and severity of spinal cord injury (SCI, complete or incomplete)) regarding 561 hospitalized TSCI patients whose injuries occurred between 2001 and 2010 was retrospectively analyzed. RESULTS Among the 561 patients, the youngest was 9 months old and the oldest was 67 years old; the average patient age was 34.74 ± 12.24 years. The sex ratio was 4.1:1 (male:female). The injuries were primarily caused by transportation accidents (51.2%), falling from a height (23.9%), tamping (8.6%), stumbling (8.0%), stabbing (3.0%) and crushing (1.8%). Although no statistically significant associations were observed between the different injury causes and severity of the injury, a statistically significant association was observed between the different injury causes and levels of the lesion. CONCLUSION Transportation accidents, falling from a height, tamping, stumbling, stabbing and crushing are the most common causes of TSCI. No statistically significant relationships were observed between certain injury causes and either complete or incomplete injury. However, different injury causes usually led to different levels of the lesion. No statistical differences were observed between the levels of the lesion and either complete or incomplete injury.

Abstract
The Na+- and Cl−-dependent GABA-betaine transporter (BGT1) has received attention mostly as a protector against osmolarity changes in the kidney and as a potential controller of the neurotransmitter GABA in the brain. Nevertheless, the cellular distribution of BGT1, and its physiological importance, is not fully understood. Here we have quantified mRNA levels using TaqMan real-time PCR, produced a number of BGT1 antibodies, and used these to study BGT1 distribution in mice. BGT1 (protein and mRNA) is predominantly expressed in the liver (sinusoidal hepatocyte plasma membranes) and not in the endothelium. BGT1 is also present in the renal medulla, where it localizes to the basolateral membranes of collecting ducts (particularly at the papilla tip) and the thick ascending limbs of Henle. There is some BGT1 in the leptomeninges, but brain parenchyma, brain blood vessels, ependymal cells, the renal cortex, and the intestine are virtually BGT1 deficient in 1- to 3-mo-old mice. Labeling specificity was assured by processing tissue from BGT1-deficient littermates in parallel as negative controls. Addition of 2.5% sodium chloride to the drinking water for 48 h induced a two- to threefold upregulation of BGT1, tonicity-responsive enhancer binding protein, and sodium- myo-inositol cotransporter 1 (slc5a3) in the renal medulla, but not in the brain and barely in the liver. BGT1-deficient and wild-type mice appeared to tolerate the salt treatment equally well, possibly because betaine is one of several osmolytes. In conclusion, this study suggests that BGT1 plays its main role in the liver, thereby complementing other betaine-transporting carrier proteins (e.g., slc6a20) that are predominantly expressed in the small intestine or kidney rather than the liver.

Abstract
CONTEXT Progesterone administration reduces the risk of preterm labor in high-risk women with singleton pregnancies but has no effect in women with a multiple pregnancy. OBJECTIVE We investigated whether progesterone is able to inhibit stretch-induced gene expression and/or whether stretch in turn inhibits progesterone action, perhaps providing an explanation for the functional progesterone withdrawal associated with human labor. METHODS AND RESULTS In a series of in vitro studies using primary cultures of human myometrial cells, we found that preincubation with progesterone did not block stretch-induced ERK1/2 activation and cyclooxygenase-2 mRNA expression. Furthermore, we found that stretch did not alter the ability of progesterone to: 1) modulate progesterone-responsive gene expression; 2) activate a luciferase-linked progesterone response element; or 3) repress IL-1β-driven cyclooxygenase-2 mRNA expression. We did find that stretch reduced the expression of progesterone receptor mRNA via nuclear factor κB activation but that this did not alter myometrial progesterone response. CONCLUSION These data show that progesterone does not inhibit stretch-induced MAPK activation or gene expression, possibly explaining why progesterone is ineffective in the prevention of preterm labor in multiple pregnancy. Although stretch did reduce progesterone receptor expression in a nuclear factor κB-dependent manner, this was not sufficient to inhibit progesterone action, suggesting that it is not responsible for the functional progesterone withdrawal observed with the onset of human labor.

Abstract
Gamma-aminobutyric acid (GABA) is the major inhibitory neurotransmitter in the mammalian brain. Once released, it is removed from the extracellular space by cellular uptake catalyzed by GABA transporter proteins. Four GABA transporters (GAT1, GAT2, GAT3 and BGT1) have been identified. Inhibition of the GAT1 by the clinically available anti-epileptic drug tiagabine has been an effective strategy for the treatment of some patients with partial seizures. Recently, the investigational drug EF1502, which inhibits both GAT1 and BGT1, was found to exert an anti-convulsant action synergistic to that of tiagabine, supposedly due to inhibition of BGT1. The present study addresses the role of BGT1 in seizure control and the effect of EF1502 by developing and exploring a new mouse line lacking exons 3-5 of the BGT1 (slc6a12) gene. The deletion of this sequence abolishes the expression of BGT1 mRNA. However, homozygous BGT1-deficient mice have normal development and show seizure susceptibility indistinguishable from that in wild-type mice in a variety of seizure threshold models including: corneal kindling, the minimal clonic and minimal tonic extension seizure threshold tests, the 6Hz seizure threshold test, and the i.v. pentylenetetrazol threshold test. We confirm that BGT1 mRNA is present in the brain, but find that the levels are several hundred times lower than those of GAT1 mRNA; possibly explaining the apparent lack of phenotype. In conclusion, the present results do not support a role for BGT1 in the control of seizure susceptibility and cannot provide a mechanistic understanding of the synergism that has been previously reported with tiagabine and EF1502.

Abstract
Amplification of femtosecond pulses at 1.56 microm based on noncollinear parametric chirped pulse amplification in a potassium titanyl arsenate (KTA) crystal with pumping at 1.05 microm is reported. The 100 fs pulses of an erbium fiber laser are parametrically amplified while synchronously pumped by an amplified mode-locked Nd:YLF laser. This amplifier has a saturated gain of 65 dB with 30% conversion efficiency and has produced 160 fs pulses with peak powers of up to 0.75 GW. The system produced 380 mW before compression and can be readily scaled to the multiwatt range with bandwidths to support sub-100 fs pulses.

Abstract
We propose the use of an auxiliary lens or mirror to design a compact dynamically stable resonator for single-rod lasers. It was found that an intracavity divergent element (divergent lens or convex mirror) is suitable for obtaining a large TEM(00)-mode volume, whereas a convergent one renders the resonator insensitive to mechanical misalignment. A reliable and compact dynamically stable resonator can be designed conveniently by use of such characteristics. Both three- and four-element resonators were designed and tested with a laser-diode side-pumped Nd:YAG laser.

Abstract
The contents of Zn, Mn, Cu and Fe in 7 kinds of treatment gastritis Chinese traditional medicines are determined by FAAS. The results show that element Fe in medicines is very rich, but element Cu is lower. The relationship between trace elements and the factor that causes gastritis is discussed. It provides useful reference data for discussing the relations of trace elements and treatment of gastroenteritis.
