Abstract
The composites formed by whey protein isolate (WPI) and octenyl succinate anhydride (OSA)-modified starch were characterized with a focus on the effect of pH, and their potential in fabricating high internal phase emulsions (HIPEs) as fat substitutes was evaluated. The particles obtained at pH 3.0, 6.0, 7.0, and 8.0 presented a nanosized distribution (122.04 ± 0.84 nm-163.24 ± 4.12 nm) while those prepared at pH 4.0 and 5.0 were remarkably larger. Results from the shielding agent reaction and Fourier transform infrared spectroscopy (FT-IR) showed that the interaction between WPI and OSA starch was mainly hydrophobic at pH 3.0-5.0, while there was a strong electrostatic repulsion at pH 6.0-8.0. A quartz crystal microbalance with dissipation (QCM-D) study showed that remarkably higher ΔD and lower Δf/n were observed at pH 3.0-5.0 after successive deposition of WPI and OSA starch, whereas slight changes were noted for those made at higher pH values. The WPI-OSA starch (W-O) composite-based HIPEs made at pH 3.0 and 6.0-8.0 were physically stable after long-term storage, thermal treatment, or centrifugation. Incorporation of HIPE into the biscuit formula yielded products with a desirable sensory quality.

Abstract
Gastric cancer (GC) is a prevalent form of cancer, with Helicobacter pylori (H. pylori) infection being the most common risk factor. Recent studies have highlighted the role of long-term irritation of the gastric mucosa caused by bile reflux in the development of cancer. Bile acids (BAs), which are a significant component in bile reflux, have the potential to promote gastric carcinogenesis through various mechanisms. These mechanisms include the induction of intestinal metaplasia (IM), inhibition of H. pylori activity, modification of H. pylori colonization, and alteration of the abundance and composition of microorganisms in the stomach. Defining the mechanism of bile acid-induced gastric carcinogenesis could potentially be an effective approach to prevent GC. Hence, this paper aims to review the mechanism of bile acid-induced IM, the association between BAs and H. pylori infection as well as microorganisms in the stomach, and the correlation between BAs and gastric carcinogenesis. The ultimate goal is to elucidate the role of BAs in the development of GC.

Abstract
Objective: To evaluate the effect of "Smoking cessation: Doctor first" program on smoking medical staff. Methods: From December 2016 to September 2019, 1 747 smoking medical staff from 54 units of China Tobacco Cessation Alliance were enrolled into"Smoking cessation: Doctor first"program. Demographic characteristics, smoking characteristics, degree of tobacco dependence, willingness to quit smoking and other related factors were collected during the baseline survey. Multivariate logistic regression model was used to analyze the related factors of willingness to quit. The subjects were given intensive smoking cessation intervention from October 2017 to September 2019, including education on the hazards of smoking, methods of smoking cessation and giving smoking cessation drugs. After intervention, the subjects were investigated about their smoking cessation progress and the effect of the project was evaluated. Results: The subjects were (41±11) years old, 91.9% (1 609/1 747) were male and 62.2% (1 086/1 747) were daily smokers. The main reasons for smoking included the influence of friends [697 (39.9%)], the need for social entertainment [629 (36.0%)], the relief of mental stress [589 (33.7%)] and the refreshment [459 (26.3%)]. At baseline, 52.9% (885/1 672) and 43.2% (755/1 747) smokers had intention to quit smoking and had planned to quit within one year, respectively. Multivariate logistic regression model analysis showed that: low education level [OR (95%CI) of high school and junior high school and below were 2.42 (1.61, 3.63) and 1.57 (1.18, 2.11)], daily smoking [OR (95%CI): 1.38 (1.06, 1.78)], thinking quitting smoking is not important [OR (95%CI): 4.15 (3.33, 5.18)] and having no quitting experience [OR (95%CI): 3.21 (2.53, 4.05)] were associated with no intention to quit smoking. After intensive smoking cessation intervention, 81.0% (1 415/1 747) smokers started to quit and 36.6% (518/1 415) quit smoking with drugs, both higher than the baseline level (all P values<0.001). By the end of the program, 60.2% (852/1 415) of the medical staff had quit smoking successfully. Conclusion: "Smoking cessation: Doctor first"program can improve the willingness to quit and the proportion of using smoking cessation drugs of medical staff.

Abstract
Objective: To investigate the sleep quality of prison policemen and explore its influencing factors, so as to provide reference for improving the sleep quality of prison policemen. Methods: In August 2013, 177 policemen in a prison were selected by cluster sampling. The sleep quality of 177 prison policemen was investigated by Pittsburgh Sleep Quality Index Scale and General Situation Questionnaire, and the influencing factors were analyzed. Results: The PSQI scores of 177 prison policemen were (7.47+3.80). There were significant differences between the PSQI scores of prison policemen and the normal adult norm (P<0.05). According to the standard of poor sleep quality, 84 prison policemen (47.46%) had poor sleep quality, and the prison policemen scored higher on daytime dysfunction, subjective sleep quality, sleeping time and sleeping time components. Single factor t test and single factor variance analysis showed that there were significant differences in sleep quality among prison policemen in gender, age, educational level and job classification (P <0.05). The results of multiple stepwise regression analysis showed that gender, age and job classification entered the regression equation with PSQI total score as dependent variable (β=0.167, 0.270, 0.222) . Conclusion: The sleep quality of prison policemen is worse than that of normal adults, and is affected by gender, age, job classification and other factors, which should be paid attention to by prison administrators.

Abstract
Objective: To investigate the sleep quality of the employed nurses in three grade A tertiary military hospitals in Beijing, China and its influential factors and to provide a reference for improving the sleep quality of employed nurses. Methods: From January 2014 to January 2017, a questionnaire survey was carried out to investigate the sleep quality of 253 employed nurses in three grade A tertiary military hospitals in Beijing, China using the Pittsburgh Sleep Quality Index (PSQI) and a general status questionnaire. The results were compared with the adult norms to analyze the influential factors for sleep quality of the employed nurses. Results: The global PSQI score of the 253 employed nurses was 7.76 ± 3.53. Their global PSQI score and PSQI component scores were significantly higher than the adults norms (P<0.05) . And 54.94% of the employed nurses had poor sleep quality; they had high scores of daytime dysfunction (1.39±0.83) , sleep latency (1.67±0.94) , sleep quality (1.33±0.88) , and sleep time (1.23±0.78) . The one-way analysis of variance showed that the sleep quality of the employed nurses was associated with nursing age, educational background, professional title, whether to have children, frequency of night shifts, and department (P<0.05) . The multivariate logistic regression analysis showed that the risk factors for sleep quality of the employed nurses were technical secondary school education (OR=4.292) and emergency department and intensive care unit (OR=2.582) ; the protective factors for sleep quality of the employed nurses were outpatient department and assistant department (OR=0.312) , no children (OR=0.318) , and no night shift (OR=0.332) . Conclusion: The employed nurses in military hospitals have poorer sleep quality than the normal adults. The influential factors for sleep quality of employed nurses are educational background, department, whether to have children, and frequency of night shifts.

Abstract
Objective: To evaluate the surgical technique and outcomes of uteri retrieval from brain-dead multi-organ donors.This study is a preclinical research of human living uterine transplantation. Methods: From May, 2015 to May, 2017, four uteri retrieval procedures, characterized with radical hysterectomy and uterine vascular pedicles dissection, were performed in multi-organ brain-dead donors.The uterus was the third authorized organ after the kidney and liver retrieval procedures in the first two cases.The uterine pedicles included the uterus, ovaries, fallopian tubes, the upper one-third of the vagina and internal iliac vessels or external iliac vessels.The perfusion of the uterus was conducted after the retrieval for evaluating the availability, followed by histopathological examination of the uterine issues per 30 minutes. Results: Since the uterine vein was quite difficult to identify and dissect in the first two case, which result in the rupture of triple uterine veins.Therefore, the uterine venous vessels including uterine vein connected with internal iliac vein and internal iliac arteries were selected as vascular grafts and dissected successfully in the last two cases, which could be perfused with the mixture of 4 ℃ heparinized physiological saline through each artery because of shortening the surgical time and arranging the uterine procurement as the first authorized organ procedure.Mean (SD) operative time was 152.5±39.0 min (115-215 min, n=4). Conclusion: Our preliminary experience indicated that the uterus could be retrieved from the brain-dead multi-organ donors and transplanted to the recipient.The attempt of skeletonizing the uterine veins should be replaced by dissection of internal iliac vein.

Abstract
Objective:To investigate the clinical significance and value of the sleep apnea monitoring management platform in the treatment of patients with obstructive sleep apnea hypopnea syndrome (OSAHS) by comparing with the traditional continuous positive airway pressure (CPAP) card reader mode.Method:A total of 48 severe adult OSAHS patients from Department of Otorhinolaryngology Head and Neck Surgery-Sleep Medical Center of the Third People's Hospital of Honghe during the period of Nov. 2015 to Aug. 2016 were collected in this prospective study. All of them were diagnosed by PSG and treated with nasal continuous positive airway pressure. They were randomly divided into group A (n=24) and group B (n=24). Group A and B were treated with the traditional CPAP card reader mode and the sleep apnea monitoring management platform respectively. During the follow-up, the compliance, mean blood oxygen saturation, titration pressure, Epworth sleepiness scale after 1, 3, 6 and 12 month treatment were compared between two groups. Ttest was used to analyze the difference. Statistical significance was set at P <0.05.Result:Statistical analysis showed that there were significant difference in the compliance of using CPAP, mean blood oxygen saturation and Epworth sleepiness scale score between the two groups (P < 0.05), but the titration pressure had no difference between the two groups (P>0.05).Conclusion:Compared the sleep apnea monitoring management platform with traditional CPAP card reader mode in the treatment of OSAHS patients, the former could solve the problems during the CPAP use in time, improve the compliance of using CPAP, and which could increase the efficacy of CPAP. Thus, the sleep apnea monitoring management platform is of more clinical value and deserve promotion.

Abstract
Cardiomyocyte apoptosis plays key roles in the pathogenesis of heart diseases such as myocardial infarction. MicroRNAs are important regulators of gene expression, which are also involved in the regulation of cardiomyocyte apoptosis. However, cardiomyocyte apoptosis regulated by microRNA (miR)-122 is largely unexplored. The aim of this study focused on the role of miR-122 in cardiomyocyte apoptosis. Cardiomyocytes were isolated from neonatal mice and primarily cultured. MiR-122 mimic and inhibitor were transfected to cardiomyocytes and verified by qRT-PCR. Cell viability and apoptosis post-transfection were assessed by MTT assay and flow cytometry, respectively. Changes in expression of caspase-8 were quantified by qRT-PCR and western blot. Results showed that miR-122 mimic and inhibitor successfully induced changes in miR-122 levels in cultured cardiomyocytes (P<0.01). MiR-122 overexpression suppressed viability and promoted apoptosis of cardiomyocytes (P<0.05), and miR-122 knockdown promoted cell viability and inhibited apoptosis (P<0.05). The mRNA and protein levels of caspase-8 were elevated by miR-122 overexpression (P<0.01) and reduced by miR-122 knockdown (P<0.001). These results suggest an inductive role of miR-122 in cardiomyocyte apoptosis, which may be related to its regulation on caspase-8.

Abstract
The impact of impurity ions on a pedestal has been investigated in the HL-2A Tokamak, at the Southwestern Institute of Physics, Chengdu, China. Experimental results have clearly shown that during the H-mode phase, an electromagnetic turbulence was excited in the edge plasma region, where the impurity ions exhibited a peaked profile. It has been found that double impurity critical gradients are responsible for triggering the turbulence. Strong stiffness of the impurity profile has been observed during cyclic transitions between the I-phase and H-mode regime. The results suggest that the underlying physics of the self-regulated edge impurity profile offers the possibility for an active control of the pedestal dynamics via pedestal turbulence.

Abstract
Linear regularization has been applied to the HL-2A infrared imaging bolometer to reconstruct local plasma emission with one-dimensional (1D) and three-dimensional (3D) modeling under the assumption of toroidal symmetry. In the 3D modeling, a new method to calculate the detector point response function is introduced. This method can be adapted to an arbitrarily shaped pinhole. With the full 3D treatment of the detector geometry, up to 50% of the mean-squared error is reduced compared with the 1D modeling. This is attributed to the effects of finite detector size being taken into account in the 3D modeling. Meanwhile, the number of the bolometer pixels has been optimized to 20 × 20 by making a trade-off between the number of bolometer pixels and the sensitivity of the system. The plasma radiated power density distributions have been calculated as a demonstration using 1D modeling and 3D modeling, respectively.

Abstract
The frequency modulated continuous wave reflectometer was developed for the first time on the HL-2A tokamak. The system utilizes a voltage controlled oscillator and an active multiplier for broadband coverage and detects as heterodyne mode. Three reflectometers have been installed and operated in extraordinary mode polarization on HL-2A to measure density profiles at low field side, covering the Q-band (33-50 GHz), V-band (50-75 GHz), and W-band (75-110 GHz). For density profile reconstruction from the phase shift of the probing wave, a corrected phase unwrapping method is introduced in this article. The effectiveness of the method is demonstrated. The density profile behavior of a fast plasma event is presented and it demonstrates the capability of the reflectometer. These diagnostics will be contributed to the routine density profile measurements and the plasma physics study on HL-2A.

Abstract
A 2D electron cyclotron emission imaging (ECEI) system has been developed for measurement of electron temperature fluctuations in the HL-2A tokamak. It is comprised of a front-end 24 channel heterodyne imaging array with a tunable RF range spanning 75-110 GHz, and a set of back-end ECEI electronics that together generate 24 × 8 = 192 channel images of the 2nd harmonic X-mode electron cyclotron emission from the HL-2A plasma. The simulated performance of the local oscillator (LO) optics and radio frequency (RF) optics is presented, together with the laboratory characterization results. The Gaussian beams from the LO optics are observed to properly cover the entire detector array. The ECE signals from the plasma are mixed with the LO signal in the array box, then delivered to the electronics system by low-loss microwave cables, and finally to the digitizers. The ECEI system can achieve temporal resolutions of ~μs, and spatial resolutions of 1 cm (radially) and 2 cm (poloidally).

Abstract
The diamagnetic concentric loop method in the HL-2A tokamak is described in this article. The system consists of two concentric poloidal loops with different areas enclosing the plasma column and a short time constant differential integrator, RC < 1 ms. The diamagnetic flux in HL-2A ranges from 1 mWb to 2 mWb for typical discharges with plasma current Ip = 100-400 kA. The integrator output ranges from 0.1 V to 0.2 V with time constant RC = 0.5 ms, and differential area ΔS∕Sout ≈ 7%. Using hybrid analog-digital compensation, the integration drift can be well compensated within 5 mV∕10 s, which can meet the requirement of the concentric loop system. In this method, the measurement of differential area ΔS is not required. The vacuum toroidal flux can be compensated by adjusting the resistance in the integration circuit for several discharges with toroidal field only, which minimizes the additional error produced by a measurement of differential area. The diamagnetic concentric loop system improved the signal to noise ratio by using the short time constant integration. The system with a resolution of ±0.2 kJ can be used to study rapid changes in plasma stored energy, such as the additional power absorbed by the plasma, and the energy loss caused by edge localized modes.

Abstract
The Choi-Williams distribution (CWD) technique is introduced as a time-frequency tool for processing data measured from the new developed homodyne and the fixed frequency reflectometry in the HL-2A tokamak. The comparison between spectrogram and CWD for the simulated signal is presented. It indicates that the CWD can greatly improve the representation of the time-frequency content of the multi-components signal. Its effectiveness is demonstrated through two applications in HL-2A, which are the extraction of beat frequencies from the frequency modulated-continuous wave reflectometry (FM-CW) and the characterizing of the fluctuations. The density profile inversed from the group delay of the FM-CW and the density fluctuations deduced from the fixed-frequency reflectometry would be more reliable and accurate by using the CWD technique.

Abstract
As a more effective in vivo drug delivery system, several methods loading anti-cancer drugs to biodegradable and biocompatible nano-particles have been explored and developed. Supposedly due to the enhanced permeability and retention (EPR) effect, systemic administration of these nano-particles have been found to result in accumulation of nano-particles into solid tumors. In this study, we prepared nano-particles using polyethylene glycol (PEG)/poly-L-lactide (PLLA) diblock copolymer and loaded doxorubicin into these nano-particles (Nano-dox). The fabricated nano-particles exhibited sustained release kinetics of the drug in vitro. To follow the in vivo biodistribution of 200-350 nm sized nano-dox particles in tumor (syngenic renal cell adenocarcinoma: RENCA) bearing mouse, the carboxylfluorescenin diacetate succinimidyl ester (CFSE) was loaded into the nano-particles. Nano-dox accumulated preferentially in tumors; however, in terms of its anti-tumor efficacy, it did not show any marked benefits, compared to freely-administered doxorubicin. This result suggests the need to re-consider and evaluate what type of anti-cancer reagents we to be used in the ongoing efforts of coupling drug delivery system with tumor EPR effects.

Abstract
The production of IL-2, IL-6 by fetal splenic mononuclear cells (FSMC) and relationship between them and the ontogenetic development of natural killer cell function were studied in human fetal spleens. As a results, before 20 weeks of gestation, both IL-2 and NK cell activities were not measured, but IL-6 was done. It was found that IL-2, IL-6 and NK cell activities were increased with the gestational age, and shown that there were linear positive correlation between the activities of three ones above (r > 0.86). Before the birth, the induced IL-2 activity was the same as adult levels (p > 0.05), although both IL-6 production and NK activity in fetal spleens were significantly lower than that in adults (p < 0.01). Lastly, the production of IL-2, IL-6 in relation to the functional development of NK cells during the embryonic development was discussed.

Abstract
UNLABELLED 12 cases of post-traumatic RDS treated with Dachengqi Decoction were reported. RESULTS 10 patients survived, which showed a bright prospect for the treatment of post-traumatic RDS. In the experimental study, model of RDS was set up in rabbits. The pressure of PaO2 was determined and the morphologic changes of their lung tissues was observed after the rabbits were perfused with Dachengqi Decoction. The results showed that their PaO2 were markedly increased and lung conditions greatly improved, which provided an experimental basis for RDS with Dachengqi Decoction. Among 12 cases; nine were moderate cases and three serious ones. During the course of treatment with Dachengqi Decoction, two patients died, covering only 16.6% of the total number of patients. This fact confirms the efficacy of Dachengqi Decoction in treating the post-traumatic RDS.

Abstract
We studied 14 cases of myasthenia gravis (MG) with regard to their anti-acetylcholine receptor antibody (AChR-Ab) production, peripheral blood CD4+/CD8+ ratio, and responses of peripheral lymphocytes to PHA and PWM stimulations. We found that the clinical severity was not proportional to AChR-Ab level in serum in terms of whole myasthenic population, whereas in one individual patient there was a close correlation between clinical severity and the AChR-Ab level in serum. The CD4+/CD8+ ratio in myasthenic patients was significantly higher than that of normal controls. The responses of T- and B-cells to mitogenic stimulations were impaired in myasthenic patients. The immune abnormalities found in the majority of the patients were restored to about normal after spleen cell dialyzable extracts (SCDE) therapy was applied to all patients. The results implicated that SCDE, working as an immunomodulator, could serve as a promising agent to normalize the abnormal immune functions of MG patients or other autoimmune diseases.
