Abstract
Quasi-solid-state batteries (QSSBs) are gaining widespread attention as a promising solution to improve battery safety performance. However, the safety improvement and the underlying mechanisms of QSSBs remain elusive. Herein, a novel strategy combining high-safety ethylene carbonate-free liquid electrolyte and in situ polymerization technique is proposed to prepare practical QSSBs. The Ah-level QSSBs with LiNi0.83Co0.11Mn0.06O2 cathode and graphite-silicon anode demonstrate significantly improved safety features without sacrificing electrochemical performance. As evidenced by accelerating rate calorimetry tests, the QSSBs exhibit increased self-heating temperature and onset temperature (T2), and decreased temperature rise rate during thermal runaway (TR). The T2 has a maximum increase of 48.4 °C compared to the conventional liquid batteries. Moreover, the QSSBs do not undergo TR until 180 °C (even 200 °C) during the hot-box tests, presenting significant improvement compared to the liquid batteries that run into TR at 130 °C. Systematic investigations show that the in situ formed polymer skeleton effectively mitigates the exothermic reactions between lithium salts and lithiated anode, retards the oxygen release from cathode, and inhibits crosstalk reactions between cathode and anode at elevated temperatures. The findings offer an innovative solution for practical high-safety QSSBs and open up a new sight for building safer high-energy-density batteries.

Abstract
The problem of thermal runaway (TR) propagation challenges the safety design of battery packs, because it aggravates the thermal hazards to accidents. There are many unsolved scientific questions in understanding the mechanisms of TR and its propagation behavior for large format lithium-ion batteries (LIBs). LiNixCoyMnzO2(NCM) is considered as one of the most promising cathode materials for lithium-ion batteries LIBs, given its higher energy design and lower cost. However, higher Nickel (Ni) content of cathode material worsens the thermal stability of LIBs. This paper provides a comparative analysis on the TR propagation behavior of NCM battery with different Ni ratios. Results have shown that when the characteristic temperatures of TR {T1, T2, T3}and the specific electrochemical energy of the cell are similar, TR propagation behavior will be similar, no matter what kinds of chemistry the cell has. Observation suggests that the average propagation time within a large format cell is 7-10 s in module tests. Besides, the internal temperature of the cell has an order of NCM622 ≥ NCM523 ≥ NCM111,whereas the mass is ordered by NCM622 > NCM523 > NCM111.This work firstly reports the TR feature in large format LIBs with different Ni ratios, both at cell and module level, providing the guidelines for engineering practice and further theoretical researches.

Abstract
To establish the experts consensus on the right heart function management in critically ill patients. The panel of consensus was composed of 30 experts in critical care medicine who are all members of Critical Hemodynamic Therapy Collaboration Group (CHTC Group). Each statement was assessed based on the GRADE (Grading of Recommendations Assessment, Development, and Evaluation) principle. Then the Delphi method was adopted by 52 experts to reassess all the statements. (1) Right heart function is prone to be affected in critically illness, which will result in a auto-exaggerated vicious cycle. (2) Right heart function management is a key step of the hemodynamic therapy in critically ill patients. (3) Fluid resuscitation means the process of fluid therapy through rapid adjustment of intravascular volume aiming to improve tissue perfusion. Reversed fluid resuscitation means reducing volume. (4) The right ventricle afterload should be taken into consideration when using stroke volume variation (SVV) or pulse pressure variation (PPV) to assess fluid responsiveness.(5)Volume overload alone could lead to septal displacement and damage the diastolic function of the left ventricle. (6) The Starling curve of the right ventricle is not the same as the one applied to the left ventricle,the judgement of the different states for the right ventricle is the key of volume management. (7) The alteration of right heart function has its own characteristics, volume assessment and adjustment is an important part of the treatment of right ventricular dysfunction (8) Right ventricular enlargement is the prerequisite for increased cardiac output during reversed fluid resuscitation; Nonetheless, right heart enlargement does not mandate reversed fluid resuscitation.(9)Increased pulmonary vascular resistance induced by a variety of factors could affect right heart function by obstructing the blood flow. (10) When pulmonary hypertension was detected in clinical scenario, the differentiation of critical care-related pulmonary hypertension should be a priority. (11) Attention should be paid to the change of right heart function before and after implementation of mechanical ventilation and adjustment of ventilator parameter. (12) The pulmonary arterial pressure should be monitored timingly when dealing with critical care-related pulmonary hypertension accompanied with circulatory failure.(13) The elevation of pulmonary aterial pressure should be taken into account in critical patients with acute right heart dysfunction. (14) Prone position ventilation is an important measure to reduce pulmonary vascular resistance when treating acute respiratory distress syndrome patients accompanied with acute cor pulmonale. (15) Attention should be paid to right ventricle-pulmonary artery coupling during the management of right heart function. (16) Right ventricular diastolic function is more prone to be affected in critically ill patients, the application of critical ultrasound is more conducive to quantitative assessment of right ventricular diastolic function. (17) As one of the parameters to assess the filling pressure of right heart, central venous pressure can be used to assess right heart diastolic function. (18). The early and prominent manifestation of non-focal cardiac tamponade is right ventricular diastolic involvement, the elevated right atrial pressure should be noticed. (19) The effect of increased intrathoracic pressure on right heart diastolic function should be valued. (20) Ttricuspid annular plane systolic excursion (TAPSE) is an important parameter that reflects right ventricular systolic function, and it is recommended as a general indicator of critically ill patient. (21) Circulation management with right heart protection as the core strategy is the key point of the treatment of acute respiratory distress syndrome. (22) Right heart function involvement after cardiac surgery is very common and should be highly valued. (23) Right ventricular dysfunction should not be considered as a routine excuse for maintaining higher central venous pressure. (24) When left ventricular dilation, attention should be paid to the effect of left ventricle on right ventricular diastolic function. (25) The impact of left ventricular function should be excluded when the contractility of the right ventricle is decreased. (26) When the right heart load increases acutely, the shunt between the left and right heart should be monitored. (27) Attention should be paid to the increase of central venous pressure caused by right ventricular dysfunction and its influence on microcirculation blood flow. (28) When the vasoactive drugs was used to reduce the pressure of pulmonary circulation, different effects on pulmonary and systemic circulation should be evaluated. (29) Right atrial pressure is an important factor affecting venous return. Attention should be paid to the influence of the pressure composition of the right atrium on the venous return. (30) Attention should be paid to the role of the right ventricle in the acute pulmonary edema. (31) Monitoring the difference between the mean systemic filling pressure and the right atrial pressure is helpful to determine whether the infusion increases the venous return. (32) Venous return resistance is often considered to be a insignificant factor that affects venous return, but attention should be paid to the effect of the specific pathophysiological status, such as intrathoracic hypertension, intra-abdominal hypertension and so on. Consensus can promote right heart function management in critically ill patients, optimize hemodynamic therapy, and even affect prognosis.

Abstract
Evidences have suggested that immunotherapy for ovarian cancer is effective. Immune checkpoints have emerged in the field of cancer immunotherapy. Multiple studies have shown negative regulation of TIM-3 expression on CD4+ and CD8+ T cells and other immunocytes. Overexpression of TIM-3 in innate immune cells has been found in certain types of tumor. The blockade of TIM-3 leads to sustained anti-tumor reactions. TIM-3 plays an inhibitive role for immunity in ovarian cancer. TIM-3 is involved in the development of various subtypes of ovarian cancer and thus has the potential to be a therapeutic target for treatment of ovarian cancer.

Abstract
AIMS Hypoxia and high hydrostatic pressure can induce an increase in the thickness of the tunica media and intima; secondary vasa vasorum (VV) increase to fit the remodeling of the vessel wall. We aimed to investigate the impact of high hydrostatic pressure on VV in the varicose greater saphenous veins (VGSVs) and diseased splenic veins (DSVs). METHODS We collected 34 VGSVs and DSVs. Thirty-four normal greater saphenous veins (GSVs) and splenic veins (SVs) were also collected (control group). Samples were cut into slices, and observed under both light and electron microscopy. The mean density and cross-sectional areas of the VV in the adventitia were measured. RESULTS In both VGSVs and DSVs, VV density increased, in the adventitia and exterior tunica media, offering an intensive linear distribution. However, sporadic distribution of the interior tunica media and intima were seen on light microscopy. The integrated structure of the cell nucleus of endothelial cells in VV, normal morphology and distribution of chromatin, partially hyperchromatic mitochondria matrix, fuzzy or fractured mitochondria cristae, and medullary cristae changes were observed by electron microscopy. Mean density and cross-sectional areas of VV in the adventitia of GSVs and SVs were significantly different. CONCLUSION Under high hydrostatic pressure conditions, the number of VV were increased in the wall of VGSVs and DSVs. There was heterogeneity between both types of veins. The splenic vein has a higher number of VV, but the greater saphenous vein has a higher average cross-sectional area. The same ultrastructural changes are seen in the endothelial cells of the VV in both vessels.

Abstract
The effect of nicotinic acid, thiamine, pyridoxine, biotin and riboflavin on the production of pyruvic acid by Torulopsis glabrata WSH-IP303 with glucose as carbon source and NH4Cl as sole nitrogen source was investigated. By using orthogonal experiment method, thiamine was confirmed to be the most important factor affecting the production of pyruvic acid. Based on a certain concentration range of thiamine (0.01-0.015 mg/L), glucose consumption rate can be enhanced by increasing the concentration of nicotinic acid. When the concentration of nicotinic acid, thiamine, pyridoxine, biotin and riboflavin were 8, 0.015, 0.4, 0.04 and 0.1 mg/L, respectively, the concentration and yield to glucose of pyruvic acid reached 52.4 g/L and 0.525 g/g at 48 h in flask culture, respectively. Batch culture was conducted in a 2.5 L fermentor with initial glucose concentration of 120 g/L. By adopting the optimal concentration combination of vitamins, the concentration and yield to glucose of pyruvic acid reached 69.4 g/L and 0.593 g/g at 57.5 h, which were increased by 32.4% and 13% than the best results in flask culture, respectively.

Abstract
OBJECTIVE To study the effect of Ginaton on liver microcirculation disturbance following liver xenotransplantation in rats. METHODS Ginaton was injected intravenously to recipients at a dosage of 14 mg/kg before graftng liver of guinea pigs. The portal blood flow (PBF) was measured by Doppler ultrasound at 0, 30 and 60 minutes after transplantation, and the pathologic changes of liver and heart were observed. RESULTS The reperfusion status of control group was poor and leukocyte infiltration appeared in the center of lobute following transplantation and myocardial cells were impaired. Significant reduction in PBF was found in rats following transplantation. Ginaton pretreatment distinctly ameliorated PBF. The speed of PBF was closely correlated with the pathologic changes following transplantation. CONCLUSION In the process of liver transplantation, ischemia reperfusion damage may lead to xenoheptic microcirculaton disturbance. Ginaton could improve the xenoheptic microcirculation and reduce ischemic reperfusion damage.

Abstract
A gene fragment encoding for surface antigen CS6 of enterotoxigenic of Escherichia coli has been cloned into the plasmid pXL670, a new recombinant plasmid pSS64 was obtained by transforming E. coli X6097 with asd gene deletion. A safe and effective E. coli/S. typhi bivalent candidate vaccine was constructed by introducing pSS64 into delta aroA, delta aroC, delta asd Salmonella typhi. The vaccine strain is still stable in the absence of antibiotics. Animal tests demonstrated that this strain, when administered subcutaneously in mice, could provide significant protection against the intraperitoneal challenge from wild S. typhi Ty2. Immunization of rabbit with this strain raised specific antibody responses against CS6 and Vi antigen of S. typhi. This study lays the foundation for the construction of a new E. coli/S. typhi bivalent live oral vaccine.

Abstract
A trivalent liveShigella vaccine candidate FSD01 against S.flexneri 2a, S.sonnei and S.dysenteriae I was constructed. This candidate strain was based on the S.flexneri 2a vaccine T32. By homologous recombination exchange, the chromosomalasd gene of T32 was site-specifically inactivated, resulting in the strain unable to grow normally in LB broth, while anotherasd gene of S.mutans was employed to construct an Asd(+) complementary vector. This combination ofasd (-) host/Asd(+) vector formed a balanced-lethal expression system in T32 strain. By use of this system, two important protective antigen genes coding for S.sonnei Form I antigen and Shiga toxin B subunit were cloned and expressed in T32, which led to the construction of trivalent candidate vaccine FSD01. Experimental results showed that this strain was genetically stable, but its recombinant plasmid was non-resistant. Moreover, it was able to effectively express trivalent antigens in one host and induce protective responses in mice against the challenges of the above threeShigella strains.
