Abstract
Sepsis, a life-threatening health issue, lacks effective medicine targeting the septic response. In China, treatment combining the intravenous herbal medicine XueBiJing with conventional procedures reduces the 28-day mortality of critically ill patients by modulating septic response. In this study, we identified the combined active constituents that are responsible for the XueBiJing's anti-sepsis action. Sepsis was induced in rats by cecal ligation and puncture (CLP). The compounds were identified based on their systemic exposure levels and anti-sepsis activities in CLP rats that were given an intravenous bolus dose of XueBiJing. Furthermore, the identified compounds in combination were assessed, by comparing with XueBiJing, for levels of primary therapeutic outcome, pharmacokinetic equivalence, and pharmacokinetic compatibility. We showed that a total of 12 XueBiJing compounds, unchanged or metabolized, circulated with significant systemic exposure in CLP rats that received XueBiJing. Among these compounds, hydroxysafflor yellow A, paeoniflorin, oxypaeoniflorin, albiflorin, senkyunolide I, and tanshinol displayed significant anti-sepsis activities, which involved regulating immune responses, inhibiting excessive inflammation, modulating hemostasis, and improving organ function. A combination of the six compounds, with the same respective doses as in XueBiJing, displayed percentage survival and systemic exposure in CLP rats similar to those by XueBiJing. Both the combination and XueBiJing showed high degrees of pharmacokinetic compatibility regarding interactions among the six active compounds and influences of other circulating XueBiJing compounds. The identification of XueBiJing's pharmacologically significant constituents supports the medicine's anti-sepsis use and provides insights into a polypharmacology-based approach to develop medicines for effective sepsis management.

Abstract
Objective: To explore the curative effects of medial plantar free flap in reconstructing electric burn wound and scar contracture in the palm. Methods: A retrospective observational study was conducted. From January 2020 to January 2023, 6 patients with electric burn wounds or scar contracture in the palm who met the inclusion criteria were admitted to the First Affiliated Hospital of Air Force Medical University, including 5 males and 1 female, aged 35 to 55 years. The wound area was 5.0 cm×3.0 cm-8.0 cm×7.0 cm after the debridement of electric burn wounds or resection of scar in the palm. The medial plantar free flap anastomosed with cutaneous nerve was used for wound reconstruction, with flap area of 5.5 cm×3.5 cm-8.5 cm×7.5 cm. The wound in the donor site was repaired with transplantation of abdominal full-thickness skin graft. After surgery, the survival of flaps and skin grafts were observed, the shape and texture of flap and the recovery of donor site of flap were observed, and the holding function of the affected hand was assessed. At the last follow-up, the two-point discrimination distance of flap was measured, the sensory recovery of flap was evaluated with the trial standard for the evaluation of the functions of the upper limbs of the Hand Surgery Society of the Chinese Medical Association, and the function recovery of flap was evaluated by post-surgery flap function evaluation scale. Results: After surgery, 5 flaps survived well, while the distal part of 1 flap was partially necrotic, which was repaired by medium-thickness skin graft from lateral thigh after debridement. All the skin grafts at the donor sites survived well. During follow-up of 3 to 24 months, the flap was not bloated, the texture and color were good, the match with the surrounding tissue was high, with no obvious scar contracture occurred at the donor site. The affected hand had good holding function. At the last follow-up, the two-point discrimination distance of flap was 6-8 mm, the flap sensation recovery was as follows: 5 flaps recovered to grade S3+, 1 flap recovered to grade S3, and the functional evaluation of flaps was excellent in 5 cases and good in 1 case. The patients basically returned to normal life and work. Conclusions: The medial plantar free flap with cutaneous nerve anastomosis has many advantages, such as high matching degree of appearance, good sensory recovery, and holding function of the affected hand. It is an ideal choice for the reconstruction of the electric burn wound and scar contracture in the palm.

Abstract
The present experiment was conducted to investigate the effect of different stocking densities on the organ development, blood biochemical indices, and antioxidative status of breeder pigeons during the rearing period. A total of 280 (half male and half female) 40-day-old young pigeons were allocated into 4 groups, including 3 experimental groups (in compartments of the flying room): the high stocking density (HSD) (0.308 m3/bird), standard stocking density (SD) (0.616 m3/bird), and low stocking density (LSD) (1.232 m3/bird) and a caged control (0.04125 m3/bird). The results showed that the contents of corticosterone and heat shock protein 70 in males and the corticosterone content in females were higher in the control than in the other groups. The relative weight of liver, lung, and gizzard in males of the HSD group was the highest among the 4 treatments, whereas the abdominal fat index in the control group was higher than those in the other 3 treatments. Body weight and the relative weight of liver and abdominal fat in female pigeons in HSD group increased significantly. The levels of serum urea nitrogen and uric acid in pigeons of LSD group increased significantly, while the concentration of total cholesterol and the activity of alanine aminotransferase were higher in the control group. Ion (K+, Ca2+, and Na+) concentrations in female pigeon serum were also elevated in the control. The activity of antioxidant enzymes, including the total antioxidant capacity, superoxide dismutase, and glutathione peroxidase in pigeon breast muscle and liver had different degrees of inhibition when the space room was crowded. Moreover, the level of malondialdehyde in the liver of male caged pigeons was higher than that in the other treatments. In summary, rearing in cages or at a high density caused stress responses in the breeder pigeons. The stocking density of breeder pigeons during the rearing period should be ranged from 0.616 m3/bird to 1.232 m3/bird.

Abstract
The adipose-derived stem cell exosomes are subcellular structures of adipose stem cells. They are nano-sized membrane vesicles that can transport various cell components and act on target cells by paracrine, and they play an important role in the exchanges of substance and information between cells. Scar healing is the commonest way of healing after skin tissue injury. Pathological scar can not only cause movement dysfunction, but also lead to deformity, which affects the appearance of patients and brings life and mental pressure to the patients. In recent years, many researches have shown that the adipose-derived stem cell exosomes contain a variety of bioactive molecules, which play an important role in reducing scar formation and scar-free wound healing, by affecting the proliferation and migration of fibroblasts and the composition of extracellular matrix. This article reviewed the recent literature on the roles and mechanisms of adipose-derived stem cell exosomes in scar formation, and prospected the future application and development of adipose-derived stem cell exosomes in scar treatment.

Abstract
In order to quantitatively evaluate the impact of biochar on the yield of staple crops in China, a total of 866 pairs of data from 116 published studies were collected. Meta analysis was used to quantitatively analyze the impact of biochar on the yield of staple crops in China and its influencing factors. Meanwhile, a structural equation model (SEM) was constructed to further explain the interaction among the factors. The results showed that compared with no biochar application, biochar application could improve the physical and chemical properties of the soil in the main grain fields and increase the yield of the main grain crops, with an average yield increase rate of 8.77%. Among them, when the pH of biochar was 7-8, the average yield increase rate was the highest, reaching 26.49%. When C/N<60, the average yield increase rate was 13.73%, which was significantly higher than that of C/N≥60. Applying biochar to acidic or neutral soil could give full play to its yield-increasing effect. When the amount of carbon applied was 10-20 t·hm-2, the average yield increase rate of wheat and corn was the highest. The average yield of rice was the highest when the amount of carbon was 15-25 t·hm-2. However, the yield-increasing rates of rice with different carbon application levels were similar, so it is possible to consider losing part of the yield and give consideration to the economic benefits by appropriate reduction. In addition, the yield-increasing effect of biochar decreased with the increase in application years, and generally the yield-increasing effect was not significant after three years. The SEM showed that the application amount of biochar not only directly affected the yield of staple crops but also indirectly affected the yield of staple crops by improving soil fertility, whereas biochar C/N and pH only affected the yield of staple crops by improving soil fertility. Therefore, in the future application of biochar, priority should be given to applying it to acidic or neutral soil with low fertility, and its C/N and pH should be controlled below 60 and 7-8, respectively. Soil conditions, biochar characteristics, and field management measures should be comprehensively considered to maximize the yield of staple crops. This research can provide scientific basis and theoretical basis for the popularization and rational application of biochar.

Abstract
Objective: To analyze the proportion and clinical characteristics of underdiagnosed zonulopathy in angle closure glaucoma (ACG) patients and to explore the related risk factors. Methods: Case-control study. Continuous cases of ACG patients who underwent phacoemulsification combined with intraocular lens implantation and goniosynechialysis surgery [ACG group, including acute angle closure glaucoma (AACG) and chronic angle closure glaucoma (CACG)] from November 1, 2020 to October 31, 2021 and age-related cataract patients who underwent phacoemulsification combined with intraocular lens implantation surgery in the same period (control group) were included. The diagnosis of zonulopathy was determined according to the intraoperative signs such as wrinkles of the anterior capsule during continuous circular capsulorhexis. The proportion of zonulopathy, preoperative diagnosis rate of zonulopathy, demographic characteristics, anterior chamber depth (ACD), axis length, difference of ACD in both eyes (ACD of the contralateral eye minus ACD of the operated eye) were compared between the two groups. The related risk factors were explored. The paired t-test (comparison between two groups of normally distributed data), non-parametric test (comparison between two groups of non-normally distributed data), Chi-square test (categorical variables), univariate and multivariate logistic regression analysis were used. Results: There were 104 ACG patients (104 eyes), including 63 AACG patients (63 eyes) and 41 CACG patients (41 eyes), and 117 controls (117 eyes). There was no significant difference in age (P=0.29) and gender (P=0.07) between the two groups. The ACG group had shallower anterior chamber (P<0.001), shorter axial length (P<0.001) and more ACD difference in both eyes (P<0.001). In the ACG group, the proportion of zonulopathy was 46.2% (48/104), which was significantly higher than that (6.0%, 7/117) in the control group (P<0.001). In the control group, only zonular laxity was found, while in the ACG group, besides the predominant zonular laxity (68.8%, 33/48), there was zonular dehiscence (31.3%, 15/48). The eyes with AACG (57.1%, 36/63) had a higher proportion of zonulopathy than those with CACG (29.3%, 12/41) (P=0.006). In the ACG group, only 14 cases (29.8%) were diagnosed preoperatively according to slit lamp examination and/or ultrasound biomicroscopy. The proportion of underdiagnosed zonulopathy was 70.8% in the ACG group (34/48). A smaller ACD was found to be related to the zonulopathy in the ACG group. All AACG cases with an ACD ≤2.0 mm and CACG cases with an ACD ≤1.9 mm had zonulopathy. Multivariate logistic regression showed that the ACD difference in both eyes (P=0.025) and the diagnosis of ACG (AACG vs. cataract, P<0.001; CACG vs. cataract, P=0.023) were independent risk factors associated with zonulopathy. Conclusions: The proportion of underdiagnosed zonulopathy among ACG patients is high. Better preoperative diagnostic methods for zonulopathy are needed. Zonulopathy is common in ACG patients, especially in AACG patients, suggesting that zonulopathy may be related to the pathogenesis of ACG. The shallower the ACD, the riskier the zonulopathy. ACD differences between two eyes and ACG types (including AACG and CACG) were related risk factors of zonulopathy.(This article was published ahead of print on the Online-First Publishing Platform for Excellent Scientific Researches of Chinese Medical Association Publishing House on March 11, 2022).

Abstract
Objective: To analyze the related factors of worsening renal function (WRF) in patients with acute right ventricular myocardial infarction (RVMI) during hospitalization. Methods: A total of 98 patients with acute RVMI admitted to the emergency comprehensive ward of Beijing Anzhen Hospital from August 2011 to January 2020 were enrolled in this cross-sectional study. According to the situation of WRF, the patients were divided into non-WRF group (76 cases) and WRF group (22 cases). WRF was defined as ≥0.3 mg/dL increase in serum creatinine level from baseline on day 6 of hospitalization (if hospital stay<6 days, it was at discharge). Baseline data, intravenous fluid infusion, diuretic and significant positive balance of patients' intake and output volume [any 24 h intakes and outputs ≥1 000 ml or any consecutive 72 h intakes and outputs ≥2 000 ml within 6 d of hospitalization (if hospitalization<6 d, it was from admission to discharge)] were obtained, and the differences of above indicators between the two groups were analyzed. Multiple logistic regression model was used to analyze the related factors of WRF. Results: The ages of patients in WRF group and non-WRF group were 60 (50, 68) and 63 (52, 72) years, and the male proportions were 63.6% (14 cases) and 76.3% (58 cases), respectively, and there was no significant difference (all P>0.05). The proportion of positive balance was 31.8% (7 cases) in WRF group, which was higher than 14.5% (11 cases) in non-WRF group (P=0.034). The rate of loop diuretic use in WRF group was 4.5% (1 case), lower than that in non-WRF group 10.5% (8 cases) (P=0.027). After adjusting for age, sex, baseline estimated glomerular filtration rate (eGFR), preoperative isoproterenol/temporary pacemaker/atropine use, significant positive balance of intake and output volume, and loop diuretic use, it was found that eGFR≥60 ml·min-1·1.73 m-2 and significant positive balance were associated with WRF, the OR (95%CI) were 0.71 (0.62-0.86) and 1.21 (1.02-1.43) (both P<0.05); After eliminating the variable of significant positive balance in the above model, loop diuretic use was found to be a correlation factor for WRF, with an OR (95%CI) of 0.89 (0.72-0.97) (P<0.05). Conclusions: Significant positive balance of intake and output volume during hospitalization in patients with acute RVMI is a risk factor for WRF on day 6 or at discharge. In the presence of a significant positive balance, loop diuretic use is a protective factor for WRF.

Abstract
Objective: To investigate the immune mechanism of human airway epithelial cell injury induced by invasion of Candida albicans with different biofilm formation abilities. Methods: Twenty-five strains of Candida albicans isolated and cultured in General Hospital of Ningxia Medical University from June to December 2019 were selected, and quality control strain SC5314 was used as the standard strain. An in vitro model of Candida albicans biofilm was established, and the biofilm formation ability of different Candida albicans was detected by crystal violet staining and enzyme plate method. The absorbance value at 570 nm (A570) was determined by enzyme plate method. A570≥0.5, 0.25<A570<0.5 and A570≤0.25 indicated strong biofilm Candida albicans form (SBF), moderate biofilm Candida albicans form (DRF) and weak biofilm Candida albicans form (WBF), respectively. The gas-liquid phase culture model of human airway epithelial cells was isolated and established in vitro and divided into five groups, including blank control group (n=20), standard strain group (n=20), strong biofilm group (n=19), weak biofilm group (n=17) and fluconazole-resistant group (n=18).The morphology of the epithelial cells was observed by scanning electron microscope (SEM), and the expression of marker protein in the model was detected by immunofluorescence in vitro. The level of lactate dehydrogenase (LDH) in cells was detected by microplate method, and the secretion of β-defensin (hBD2), granulocyte macrophage colony stimulating factor(GM-CSF) and granulocyte colony-stimulating factor (G-CSF) was detected by enzyme-linked immunosorbent assay (ELISA). Results: The strong biofilm strains grew with interlacing mycelia, and very few yeast cells could be seen wrapped in them.SEM observed that the mycelia of epithelial cells in gas-liquid phase culture could actively invade epithelial cells, and the expression of acetylated tubulin and keratin in cilia were significantly reduced, while the expression of Ki67 was down-regulated.The LDH levels in the blank control group, standard strain group, strong biofilm group, weak biofilm group, and fluconazole-resistant group were (12.21±5.68), (46.35±6.35), (18.69±4.38), (12.56±3.69), and (13.48±4.28) U/L, respectively, with statistically significant differences (P<0.001). Compared with standard strain group, LDH level in strong biofilm group, weak biofilm group and fluconazole resistant group were significantly decreased (all P<0.01). The hBD2 levels of the five groups were (26.14±0.77), (56.18±0.83), (30.66±2.59), (29.22±0.48), (28.28±1.56) ng/L, respectively, with statistically significant differences(P<0.001). Compared with the blank control group, SC5314-treated epithelial cells induced an increase of intracellular hBD2 expression (P<0.001). The differences in the expression of GM-CSF and G-CSF between different groups were not statistically significant(all P>0.05). Conclusion: Strong biofilm Candida albican can inhibit cell proliferation, disrupt the integrity of epithelial cells and induce cell damage by down-regulating the expression of cell proliferation-related protein.

Abstract
AIM To evaluate the role of dual-energy computed tomography perfusion (DECTP) imaging in differentiating invasive thymomas (ITs), thymic cancers (TCs), and lymphomas in adults. MATERIALS AND METHODS Ninety-five patients with solid masses in the prevascular mediastinum who underwent DECTP examinations were enrolled in this study. The perfusion parameters (blood flow, BF; blood volume, BV; mean transit time, MTT; permeability surface, PS) and spectral parameters (water concentration, WC; iodine concentration, IC; normalised iodine concentration, NIC; the slope of spectral radiodensity [Hounsfield units] curve, λHU) of the lesions were analysed. RESULTS There were no differences in the MTT or WC values among ITs, TCs, and lymphomas (all p>0.05). The IC, NIC, and λHU values in the optimal arterial and venous phases and PS values of TCs were higher than those of ITs and lymphomas (all p<0.05), and there were no differences between ITs and lymphomas (all p>0.05). The BF and BV values of lymphomas were lower than those of ITs and TCs (all p<0.05), and there were no differences between ITs and TCs (all p>0.05). The cut-off values for BF and BV used to differentiate lymphomas from ITs and TCs were 42.83 ml/min/100 g and 4.66 ml/100 g, respectively (area under the receiver operating characteristic curve: 0.847 and 0.839; sensitivity, 80.6% and 82.1%; specificity, 75% and 71.4%; accuracy, 78.9% and 81.1%). CONCLUSIONS The perfusion and spectral parameters of DECTP imaging help to identify ITs, TCs, and lymphomas, and BF and BV values help to differentiate lymphomas from ITs and TCs.

Abstract
Postoperative fatigue (POF) is the most common and long-lasting complication after surgery, which brings heavy burden to individuals and society. Recently, hastening postoperative recovery receives increasing attention, but unfortunately, the mechanisms underlying POF remain unclear. Propofol is a wildly used general anesthetic in clinic, and inspired by the rapid antidepressant effects induced by ketamine at non-anesthetic dose, the present study was undertaken to investigate the anti-fatigue effects and underlying mechanisms of propofol at a non-anesthetic dose in 70% hepatectomy induced POF model in rats. We first showed here that single administration of propofol at 0.1 mg/kg ameliorated acute POF in hepatectomy induced POF rats. Based on metabonomics analysis, we hypothesized that propofol exerted anti-fatigue activity in POF rats by facilitating free fatty acid (FFA) oxidation and gluconeogenesis. We further confirmed that propofol restored the deficit in FFA oxidation and gluconeogenesis in POF rats, as evidenced by the elevated FFA utilization, acetyl coenzyme A content, pyruvic acid content, phosphoenolpyruvic acid content, hepatic glucose output and glycogen storage. Moreover, propofol stimulated glucagon secretion and up-regulated expression of cAMP-response element binding protein (CREB), phosphorylated CREB, peroxlsome prolifeator-activated receptor-γ coactivator-1α (PGC-1α), phosphoenolpyruvate carboxykinade1 and carnitine palmitoltransferase 1A. In summary, our study suggests for the first time that propofol ameliorates acute POF by promoting glucagon-regulated gluconeogenesis via CREB/PGC-1α signaling and accelerating FFA beta-oxidation.

Abstract
Sepsis is defined as life-threatening organ dysfunction caused by a dysregulated host response to infection. Sestrin2 (SESN2), a highly evolutionarily conserved protein, is critically involved in the cellular response to various stresses and has been confirmed to maintain the homeostasis of the internal environment. However, the potential effects of SESN2 in regulating dendritic cells (DCs) pyroptosis in the context of sepsis and the related mechanisms are poorly characterized. In this study, we found that SESN2 was capable of decreasing gasdermin D (GSDMD)-dependent pyroptosis of splenic DCs by inhibiting endoplasmic reticulum (ER) stress (ERS)-related nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3)-mediated ASC pyroptosome formation and caspase-1 (CASP-1) activation. Furthermore, SESN2 deficiency induced NLRP3/ASC/CASP-1-dependent pyroptosis and the production of proinflammatory cytokines by exacerbating the PERK–ATF4–CHOP signaling pathway, resulting in an increase in the mortality of septic mice, which was reversed by inhibiting ERS. These findings suggest that SESN2 appears to be essential for inhibiting NLRP3 inflammasome hyperactivation, reducing CASP-1-dependent pyroptosis, and improving sepsis outcomes through stabilization of the ER. The present study might have important implications for exploration of novel potential therapeutic targets for the treatment of sepsis complications.

Abstract
Sepsis has emerged as a global health issue, and accounts for millions of deaths in intensive care units. Dysregulation of the immune response reportedly contributes to the pathogenesis and progression of this lethal condition, which involves both the dysfunction of immune cells and incompetent immunomodulatory mechanisms. High mobility group box 1 (HMGB1) is known as a later inflammatory mediator and is critically involved in the severity and prognosis of sepsis by inducing intractable inflammation and dysfunction of various immune cells. In the present study, we found that intracerebroventricular (ICV) injection of Box A, a specific antagonist of HMGB1, restored the dysregulated response of splenic dendritic cells (DCs) in septic mice by enhancing the expression of surface molecules, including CD80, CD86, and MHC-II, as well as improving DC priming of T lymphocytes. Cerebral HMGB1 was also confirmed to have potent inhibitory effects on DC functions when administrated by ICV injection in normal mice. The brain cholinergic system was found to mediate the immunomodulatory effects of central HMGB1, as it exhibited enhanced activity with persistent HMGB1 exposure. Furthermore, the inhibitory effects of cerebral HMGB1 on the response of peripheral DCs were also blocked by α7nAchR gene knockout. These findings provide novel insight into the relationship between cerebral HMGB1 and splenic DC dysfunction during sepsis, which is, at least in part, dependent on cholinergic system activity.

Abstract
Ferroptosis is a nonapoptotic form of programmed cell death triggered by the accumulation of reactive oxygen species (ROS) depended on iron overload. Although most investigations focus on the relationship between ferroptosis and cancer, neurodegenerative diseases, and ischemia/reperfusion injury, research on ferroptosis induced by immune-related inflammatory diseases, especially sepsis, is scarce. Sestrin2 (Sesn2), a highly evolutionary and stress-responsive protein, is critically involved in defense against oxidative stress challenges. Upregulated expression of Sesn2 has been observed in preliminary experiments to have an antioxidative function in the context of an inflammatory response. Nevertheless, the underlying function of Sesn2 in inflammation-mediated ferroptosis in the immune system remains uncertain. The current study aimed to demonstrate the protective effect of Sesn2 on ferroptosis and even correlations with ferroptosis and the functions of ferroptotic-dendritic cells (DCs) stimulated with lipopolysaccharide (LPS). The mechanism underlying DCs protection from LPS-induced ferroptosis by Sesn2 was further explored in this study. We found that the immune response of DCs assessed by co-stimulatory phenotypes was gradually enhanced at the peak time of 12 h upon 1 μg/ml LPS stimulation while ferroptosis in DCs treated with LPS at 24 h was significantly detected. LPS-induced ferroptosis showed a suppressive impact on DCs in phenotypic maturation, which was conversely relieved by the ferroptotic inhibitor. Compared with wild-type (WT) mice, DCs in genetic defective mice of Sesn2 (Sesn2-/-) exhibited exacerbated ferroptosis. Furthermore, the protective effect of Sesn2 on ferroptosis was noticed to be associated with the ATF4-CHOP-CHAC1 pathway, eventually exacerbating ferroptosis by degrading of glutathione. These results indicate that Sesn2 can suppress the ferroptosis of DCs in sepsis by downregulating the ATF4-CHOP-CHAC1 signaling pathway, and it might play an antioxidative role.

Abstract
BACKGROUD Oxidative stress (OS) can affect the expression of key genes and destroy the intestinal structure. However, it is unclear how OS regulates the expression of circular RNAs (circRNAs), microRNAs (miRNAs) and mRNAs. OBJECTIVE The aim of this study was to examine the expression of circRNAs, miRNAs and mRNAs exposed to OS. METHODS Piglets were exposed to diquat (DQ), a herbicide, and the activity of antioxidant enzymes and the morphology of the intestine were investigated. We utilized whole transcriptome sequencing to examine the global expression of circRNAs, miRNAs and mRNAs in the jejunum. RESULTS Compared to controls, 751 circRNAs, 731 miRNAs and 164 mRNAs were differentially expressed in diquat-treated piglets. Kyoto Encyclopedia of Genes and Genomes pathway analysis indicated that oxidative phosphorylation, RNA degradation and ubiquitin-mediated proteolysis were closely associated with OS. CONCLUSIONS Our results indicated that diquat-induced OS alters the intestinal structure, resulting in the differential expression of circRNAs, miRNAs and mRNAs in the jejunum of piglets. Meanwhile, OS weakened the enzyme antioxidant system in serum of piglets. Our results provide a foundation for further studies on the mechanisms involved in the response to OS in the jejunum.

Abstract
Objective: To explore the effect of androgen replacement therapy in a rabbit dry eye model characterized by androgen deficiency and meibomian gland dysfunction (MGD). Methods: Thirty 6-month-old male Chinchilla rabbits were randomly divided into the treatment group, model group and control group, with 10 rabbits in each group. In the treatment and model groups, 2/3 of the meibomian gland openings were closed by cauterization with electric coagulation pen, and bilateral testes were removed. One gram gel containing 1% testosterone was applied for 28 days on the skin of rabbits in the treatment group since day 28 after the surgery. The model group and control group received transdermal petrolatum instead. Tear secretion, tear breakup time (TBUT), corneal fluorescein staining, and serum free testosterone level were monitored throughout the study period. The globes and eyelids were collected for hematoxylin-eosin staining and periodic acid-Schiff staining. Conjunctival tissue was tested for the expression of miRNA-744-5p and interleukin-6. Meibum was collected for fatty acid analysis. Results: Animals presented with typical dry eye signs and androgen deficiency. After 28-day androgen replacement therapy, compared with the model group, the treatment group had a significantly higher tear secretion rate [(14.7±5.2) vs (10.3±3.6) mm, P=0.001], higher TBUT [(15.0±4.2) vs (10.2±3.6) s, P=0.003], lower fluorescein staining score [0 (0, 1) vs 2 (1, 4), P<0.001], and higher goblet cell density at conjunctival fornix (27.2±7.6 vs 10.7±4.8, P<0.001). Additionally, compared with the model group, the conjunctiva of the treatment group expressed a significantly lower level of miRNA-744-5p (1.67±0.24 vs 2.63±0.58, P<0.001) and interleukin-6 [2.38 (1.84, 4.61) vs 4.82 (3.99, 6.36), P=0.022]. Meanwhile, the treatment group showed significantly increased level of 16∶1, Δ9 fatty acid [(10.31±1.00)% vs (3.87±0.45)%, P<0.001] and iso-18∶0 fatty acid [(7.09±0.93)% vs (2.44±0.70)%, P<0.001], but decreased level of iso-26∶0 fatty acid [(5.72±1.07)% vs (8.02±0.65)%, P<0.001] in the meibum compared with the model group. Conclusion: Androgen replacement therapy can alleviate dry eye signs in rabbits presented with combined androgen deficiency and MGD.

Abstract
Objective: To analyze the gender disparity and relevant factors of frailty in the elderly of communities in Beijing. Methods: From November 2015 to January 2016, 1 557 participants aged 60 and older in four communities of Dongcheng district in Beijing were recruited by cluster sampling. The information of demographic characteristics, social support, economic status, health status, prevalence situation, cognitive function, emotion and comprehensive assessment of the elderly were collected by a self-made questionnaire. The frailty index (FI) model was used to evaluate the frailty of the elderly. Multivariate nonconditional logistic regression model and Fairlie decomposition method were applied to analyze the relevant factors and their contribution rate to the difference between males and females. Results: The age of subjects was (74.5±8.5) years old, ranging from 60-102 years old, among which 641 were males, accounting for 41.2%. The M (Q1, Q3) of FI was 0.09 (0.06, 0.14), among which the value in males was 0.08 (0.05, 0.13), lower than females [0.10 (0.06, 0.15)] (P<0.001).The frail proportion in female was 14.9% (137/916), higher than that of male [8.4% (54/641)] (P<0.001). Multivariate nonconditional logistic regression model analysis demonstrated that common relevant factors associated with frailty in older women and men include: age ≥80 years old, marital status as not married (unmarried, separated, divorced, or widowed), living alone increased the risk of frailty; participating in group activities ≥3 times/week and exercising regularly decreased the risk of frailty (all P<0.05). Fairlie decomposition method showed that the contribution rate of life style, family support, marital status and social support were 32.21%, 15.26%, 8.23% and 4.34%, respectively (all P<0.05). Conclusions: The frailty degree and frailty proportion of elderly women in communities in Beijing were higher than those of men of the same age. The frailty gender difference was related to lifestyle, family support, marital status and social support.

Abstract
Objective: To explore the diagnostic value of serum amyloid A (SAA) and C-reactive protein (CRP) for predicting acute aortic dissection (AAD). Methods: One hundred and seventy-five AAD patients and 160 patients with acute coronary syndrome (disease control group) who were admitted to Cardio-cerebrovascular Disease Hospital of General Hospital of Ningxia Medical University from January 2018 to June 2020 were retrospectively selected. Meanwhile, 148 healthy subjects (healthy control group) who underwent physical examination were also enrolled. The latex-enhanced immunoturbidimetric assay and the latex immunoturbidimetric assay were used to determine the serum SAA and CRP levels of all subjects, and related clinical data were collected and analyzed. Univariate and multivariate logistic regression analyses were performed to analyze the independent risk factors, and the receiver operating characteristic (ROC) curve was drawn to calculate the diagnostic value of SAA and CRP for predicting AAD. Results: The levels of SAA and CRP in the AAD patient group ((165.7±7.4) mg/L and (76.0±4.0)mg/L) were significantly higher than those of the healthy control group ((6.5±0.4) mg/L and (3.9±0.2) mg/L) and the disease control group ((27.2±1.3) mg/L and (9.4±3.2) mg/L), with significant differences (all P<0.05). Compared with patients less than 60 years, levels of SAA and CRP in AAD patients over 60 years old decreased ((150.6±12.7) mg/L and (73.9±7.3) mg/L), and there were significant differences (both P<0.05). Likewise, SAA levels in AAD patients with high-risk pain characteristics over 6 h increased compared to those with pain less than 6 h, and there was a significant difference (P<0.05). SAA was positively correlated with CRP (r=0.053 4, P<0.05). ROC analysis showed that SAA and CRP levels were independently related to the risk of AAD (P=0.001), and the ROC curve of SAA for predicting AAD showed that the area under the curve (AUC) of type A aortic dissection (TAAD) and type B aortic dissection (TBAD) were 0.997 and 0.995, respectively (both P<0.001). And the ROC curve of CRP for predicting AAD demonstrated that the AUC of TAAD and TBAD were 0.998 and 0.991, respectively (both P<0.001). The best cut-off values of SAA and CRP for predicting AAD were 175.17 mg/L and 72.96 mg/L, respectively. Conclusion: Increased levels of SAA and CRP have high predictive value for AAD, and SAA combined with CRP is expected to serve as a laboratory marker to assist the diagnosis of AAD.

Abstract
Coronaviruses are a common class of respiratory viruses that can cause human infections. 2019 novel coronavirus(2019-nCoV), a new coronavirus that has recently caused a pandemic, has affected millions of people and put tremendous pressure on the health systems of almost every country in the world. Coronaviruses are known to spread from person to person through droplets or contact. The 2019-nCoV has also been found in the conjunctival secretions and tears of some clinically diagnosed patients. To assess whether the eye is one of the transmission routes of the virus, we review literature, and summarize the anatomy of the eye-nose pathway, the expression of the virus receptor in the eye, the preclinical animal studies, and the clinical data. We analyze the possibility of eyes as a means of transmission and propose some suggestions of ocular protection. (Chin J Ophthalmol, 2021, 57: 305-310).

Abstract
Abnormal activities in reward-related regions are associated with overeating or obesity. Preliminary studies have shown that changes in neural activity in obesity include not only regional reward regions abnormalities but also impairments in the communication between reward-related regions and multiple functional areas. A recent study has shown that the transitions between different neural networks are nonrandom and hierarchical, and that activation of particular brain networks is more likely to occur after other brain networks. The aims of this study were to investigate the key nodes of reward-related regions in obese males and explore the hierarchical integrated processing of key nodes. Twenty-four obese males and 24 normal-weight male controls of similar ages were recruited. The fMRI data were acquired using 3.0 T MRI. The fMRI data preprocessing was performed in DPABI and SPM 12. Degree centrality analyses were conducted using GRETNA toolkit, and Granger causality analyses were calculated using DynamicBC toolbox. Decreased degree centrality was observed in left ventral medial prefrontal cortex (vmPFC) and right parahippocampal/hippocampal gyrus in group with obesity. The group with obesity demonstrated increased effective connectivity between left vmPFC and several regions (left inferior temporal gyrus, left supplementary motor area, right insular cortex, right postcentral gyrus, right paracentral lobule and bilateral fusiform gyrus). Increased effective connectivity was observed between right parahippocampal/hippocampal gyrus and left precentral/postcentral gyrus. Decreased effective connectivity was found between right parahippocampal/hippocampal gyrus and left inferior parietal lobule. This study identified the features of hierarchical interactions between the key reward nodes and multiple function networks. These findings may provide more evidence for the existing view of hierarchical organization in reward processing.

Abstract
As an important technique for the detection of fingermarks on porous surfaces, 1,2-indanedione is widely used due to its excellent detection performance. In order to optimize the effectiveness of 1,2-indanedione, several institutions have modified the original formulation. In this study, four different 1,2-indanedione formulations were used to treat fingermarks deposited on different porous substrates to determine the most suitable formulation and whether Solstice-PF can be an alternative carrier solvent for the currently used HFE7100. It was found that the Solstice-PF-based formulation performed similarly to the HFE7100-based formulation on copy paper, but when treating fingermarks deposited on brown paper and newspaper, Solstice-PF was superior to HFE7100 by developing up to 10% more marks graded 3 and 4 regardless of the ageing period. The results confirm that Solstice-PF can be used as an alternative carrier solvent for 1,2-indanedione formulations with good detection rates and lower costs.

Abstract
Objective: To investigate whether CT coronary angiography (CTA) can safely and effectively reduce the number of invasive coronary angiography (ICA) in patients with non-ST-segment elevation myocardial infarction (NSTEMI) whose Grace score is low-or moderate-risk, and increase ICA positive rate. Methods: One hundred and two NSTEMI patients, including 61 males and 41 females, aged 38-80 (58±12) years, were prospectively included and treated in Henan Provincial People's Hospital from February 2017 to February 2018. By using random number method, the patients were divided into control group (51 cases) and experimental group (51 cases). Patients in the control group were arranged for elective ICA examination according to the risk stratification. If further intervention or surgical treatment was required, the ICA examination was positive; in the experimental group, the CTA examination was completed through the green channel first. If the CTA showed that the main coronary artery and its main branches were severe or extreme stenosis, further ICA examination was arranged; otherwise, a secondary prophylactic drug treatment was developed and the patients were then discharged and followed up for 1 year. ICA number, ICA positive rate, length of hospital stay, hospital cost, hospital anxiety and depression score (HADS), major cardiovascular events (MACE) within 1 year, and other serious adverse events related to examination or surgery were compared between the two groups. Results: A total of 37 patients in the experimental group underwent ICA, and the positive rate of ICA was 94.59% (35/37), which was significantly higher than that of the control group [62.75% (32/51)] (P<0.05). The average length of hospital stay and the HADS score before ICA in the experimental group were significantly lower than those in the control group [(3.8±2.2) d vs (4.8±2.4) d; 8.8±4.5 vs 11.4±6.8] (all P<0.05). There was no significant difference in the cumulative incidence of MACE (3 cases vs 5 cases, P=0.423) and other serious adverse events (8 cases vs 10 cases, P=0.548) within 1 year between the two groups. Conclusion: CTA significantly reduces the number of ICA and the average length of hospital stay, and increases the positive rate of ICA in NSTEMI patients whose Grace score is low-or moderate-risk. There is no increase in cardiovascular risks within 1 year.

Abstract
Objective: To investigate the prevalence and predictors of intraplaque hemorrhage (IPH) in ischemic stroke patients with intracranial atherosclerosis. Methods: Ischemic stroke patients with intracranial atherosclerosis who were consecutively admitted to Beijing Tsinghua Changgung Hospital from January 2017 to April 2018 were retrospectively analyzed. High-resolution magnetic resonance vessel wall imaging was used to assess atherosclerotic plaque characteristics of intracranial artery. Possible variables correlated with IPH were compared between IPH and no-IPH groups, as well as in symptomatic IPH and no symptomatic IPH groups. Logistic regression analysis was used to determine the predictors of all IPH and symptomatic IPH in intracranial artery. Results: A total of 276 ischemic stroke patients with intracranial atherosclerosis were included, of which, 41.3% (114/276) were IPH-postive, and 28.1%(32/114) of them were symptomatic. In multivariate regression analysis, maximum wall thickness was independently associated with the presence of all IPH and symptomatic IPH (OR=2.15, 95%CI: (1.42-3.24) and OR=3.46, 95%CI: (1.94-6.17), respectively). Conclusion: The prevalence of IPH in ischemic stroke patients with intracranial atherosclerosis is much higher than expected. Moreover, atherosclerosis plaque burden is independently associated with IPH, but it is non-specific in identifying symptomatic IPH.

Abstract
Objective: To explore the influence of Xuebijing injection (hereinafter referred to as Xuebijing) and its component paeoniflorin on immune function of regulatory T cells (Tregs) of spleen and survival rate of septic rats. Methods: (1) CD4(+) CD25(+) Tregs and CD4(+) T cells were isolated and purified from spleens of three 9 to 12 weeks old Sprague-Dawley male rats (the same age, breed, and gender below) by immunomagnetic beads. According to the random number table (the same grouping method below), CD4(+) CD25(+) Tregs were divided into blank control group, simple CD3/CD28 group, simple endotoxin/lipopolysaccharide (LPS) group, LPS+ Xuebijing group, and LPS+ paeoniflorin group, with 6 wells in each group. The cells in simple CD3/CD28 group, simple LPS group, LPS+ Xuebijing group, and LPS+ paeoniflorin group were cultured in RPMI 1640 medium containing fetal bovine serum in volume fraction of 10%, 1.25 μg CD3, and 2.5 μg CD28 for 24 hours. Then 1 μg/mL LPS in the volume of 1 μL was added to the cells in simple LPS group, LPS+ Xuebijing group, and LPS+ paeoniflorin group. Moreover, 5 mg/mL Xuebijing in the volume of 1 μL and 80 μmol/L paeoniflorin in the volume of 1 μL were added to the cells in LPS+ Xuebijing group and LPS+ paeoniflorin group, respectively, which were cultured for another 72 hours. Cells in blank control group were routinely cultured in RPMI 1640 medium containing fetal bovine serum in volume fraction of 10% for 96 hours. The expressions of cytotoxic T lymphocyte antigen 4 (CTLA-4) and forkhead wing-link transcription factor 3 (Foxp3) and apoptosis of CD4(+) CD25(+) Tregs were measured by flow cytometry. The interleukin-10 (IL-10) level from culture supernatant of CD4(+) CD25(+) Tregs was determined by enzyme-linked immunosorbent assay (ELISA). CD4(+) T cells were divided into blank control' group, simple CD3/CD28' group, simple LPS' group, LPS+ Xuebijing' group, and LPS+ paeoniflorin' group, with 6 wells in each group. After being cocultured with the corresponding CD4(+) CD25(+) Tregs treated as before for 72 hours, the proliferative activity of CD4(+) T cells was measured by flow cytometry, and IL-4 level from culture supernatant of CD4(+) T cells was determined by ELISA. (2) One hundred and twenty rats were divided into sham surgery group, simple sepsis group, sepsis+ Xuebijing group, and sepsis+ paeoniflorin group, with 30 rats in each group. The septic rat model was reproduced by cecal ligation and puncture surgery in simple sepsis group, sepsis+ Xuebijing group, and sepsis+ paeoniflorin group. In sham surgery group, the rats were only performed with laparotomy to simulate surgery. In sepsis+ Xuebijing group, the rats were given post-surgical injection of 4 mL/kg Xuebijing through tail vein, twice a day. In sepsis+ paeoniflorin group, the rats received 978 μg paeoniflorin via tail vein, twice a day. The survival rates of rats in the four groups on post surgery day 1, 2, 3, 4, 5, 6, and 7 were observed and recorded. The surviving cure of Kaplan-Meier was drawn. Data were statistically analyzed with one-way analysis of variance, least significant difference t test. The surviving curve was analyzed by Log-rank (Mantel-Cox) test. Results: (1) Compared with those in blank control group, the expressions of CTLA-4 and Foxp3 of CD4(+) CD25(+) Tregs (t=27.19, 17.00, P<0.01) and IL-10 level from culture supernatant (t=40.76, P<0.01) were significantly increased in rats in simple LPS group. Compared with those in simple LPS group, the expressions of CTLA-4 and Foxp3 of CD4(+) CD25(+) Tregs (t(LPS+ Xuebijing group)=31.03, 11.27, t(LPS+ paeoniflorin group)=5.79, 5.64, P<0.01) and IL-10 level from culture supernatant (t=15.49, 4.20, P<0.01) was significantly decreased in LPS+ Xuebijing group and LPS+ paeoniflorin group. Compared with that in blank control group, the apoptosis rate of CD4(+) CD25(+) Tregs in simple LPS group was significantly declined (t=6.02, P<0.01). Compared with the rate in simple LPS group, the apoptosis rates of CD4(+) CD25(+) Tregs in LPS+ Xuebijing group and LPS+ paeoniflorin group were significantly increased (t=20.32, 8.60, P<0.01). (2) Compared with those in simple CD3/CD28' group, the proliferative rate of CD4(+) T cells was significantly decreased in simple LPS' group (t=22.47, P<0.01), while IL-4 level from culture supernatant was significantly elevated (t=3.51, P<0.01). Compared with those in simple LPS' group, the proliferative rates of CD4(+) T cells in LPS+ Xuebijing' group and LPS+ paeoniflorin' group were significantly increased (t=16.31, 11.48, P<0.01), while IL-4 level from culture supernatant showed no obvious change. (3) The post-operative 7-day survival rates of rats in sham surgery group, simple sepsis group, sepsis+ Xuebijing group, sepsis+ paeoniflorin group were 100% (30/30), 30% (9/30), 57% (17/30), and 47% (14/30), respectively. Compared with that in simple sepsis group, the survival rate within post-operative 7-day of rats in sepsis+ Xuebijing group was significantly higher (χ(2)=4.34, P<0.05), while the survival rate within post-operative 7-day of rats in sepsis+ paeoniflorin group showed no obvious change. Conclusions: Both Xuebijing and its component paeoniflorin are capable of reversing sepsis-induced inhibitory immune function and apoptotic resistant of Tregs in rats, and further improving the proliferative activity of T cells. In addition, the effect of paeoniflorin on improvement of survival rate of rats with sepsis is weaker than Xuebijing.

Abstract
O-GlcNAcylation (O-GlcNAc) is a posttranslational modification that is mediated by O-GlcNAc-transferase (OGT) and reversed by O-GlcNAcase (OGA). Increasing evidence indicates that protein O-GlcNAcylation is increased in various types of cancer. In the present study, we aimed to evaluate the expression and function of both OGT and OGA in bladder cancer cells in vitro and in vivo. Expression data of OGT and OGA at the mRNA level was obtained from the Oncomine database. Effects of OGT and OGA on cell proliferate, invasive, and migratory abilities were assessed using MTT, wound healing, cell invasive assay, and cell cycle analysis. In vivo assay was also performed in nude mice. The results revealed that the expression of OGT in bladder cancer tissues was higher than that of normal tissues, while the OGA level was found to be lower in cancer tissues. We also found that knockdown of OGT could inhibit cell proliferation, migration, invasion, and induce cell cycle arrest, while these are reversed when OGA is inhibited. We also observed that O-GlcNAcylation could promote tumor formation in vivo, compared with a negative control. In summary, this study describes the oncogenic role of O-GlcNAcylation in bladder cancer cells.

Abstract
A combination of LC-MS technology and activity evaluation was used to identify the antipyretic ingredients in rhubarb. The rat model of fever was established with dried yeast and then was administered ethanol extract and different polar fractions of rhubarb. Next, the anal temperature of these rats was measured and recorded at 0.5, 1, 2, 3, 4 and 5 h after administration, and the inhibition rate of each part on the rise of body temperature was calculated. The inhibition rate is higher and the antipyretic effect is better. The chemical composition of the effective fraction was analyzed with UPLC-ESI-Orbitrap-MS/MS technology. Compared with the model group, the increase of body temperature of ethanol extract group all reduced at each measurement time especially after 3 h, and the inhibition rate were 38.7%(P<0.05), 78.2%(P<0.01) and 72.4%(P<0.01) at 3 h, 4 h, and 5 h after administration, respectively. Both n-butanol and water fraction showed some antipyretic activity in the early stage, with the inhibition rate of 28.1%(P<0.01) and 24.9%(P<0.05) at 1 h after administration, respectively, while other fractions were not active. Thirty-three and twelve compounds were identified from n-butanol and water fraction by LC-MS/MS analysis, respectively, including ten tannins, fifteen anthraquinone glycosides, four anthrone glycosides, one phenolic glycoside, one naphthaline derivative, one anthraquinone and one sucrose. These results revealed that rhubarb had antipyretic activity on rats, and tannin and anthraquinone glycosides were the main active ingredients inside.

Abstract
Sestrin2 (SESN2) is a highly evolutionary conserved protein and involved in different cellular responses to various stresses. However, the potential function of SESN2 in immune system remains unclear. The present study was designed to test whether dendritic cells (DCs) could express SESN2, and investigate the underlying molecular mechanism as well as its potential significance. Herein, we firstly reported that SESN2 was expressed in DCs after high mobility group box-1 protein (HMGB1) stimulation and the apoptosis of DCs was obviously increased when SESN2 gene silenced by siRNA. Cells undergone SESN2-knockdown promoted endoplasmic reticulum (ER) stress (ERS)-related cell death, markedly exacerbated ER disruption as well as the formation of dilated and aggregated structures, and they significantly aggravated the extent of ERS response. Conversely, overexpressing SESN2 DCs markedly decreased apoptotic rates and attenuated HMGB1-induced ER morphology fragment together with inhibition of ERS-related protein translation. Furthermore, sesn2−/−-deficient mice manifested increased DC apoptosis and aggravated ERS extent in septic model. These results indicate that SESN2 appears to be a potential regulator to inhibit apoptotic ERS signaling that exerts a protective effect on apoptosis of DCs in the setting of septic challenge.

Abstract
Purpose: Stereotactic body radiation therapy (SBRT) is emerging as a new noninvasive treatment in patients with primary liver carcinoma or liver-confined metastatic cancer. However, the radiobiological targets remain a subject of debate. Here, we investigated the potential biological effects of the radiation on the human hepatocellular carcinoma HepG2 cells.Materials and methods: Firstly, HepG2 cells were divided into three groups: control group, 3.5 Gy*8f group (L group), and 15 Gy*1f group (H group). After treatment, cell proliferation was examined using 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide and plate colony formation assays. Cell cycle and apoptosis were assessed using propidium iodide and Hoechst 33258 staining, respectively. Furthermore, the mechanisms underlying irradiation-induced cell cycle arrest and cell apoptosis were investigated by Western blot assay.Results: Irradiation could effectively inhibit the proliferation and colony formation of HepG2 cells, and the single high dose irradiation showed stronger inhibitory effects. Irradiation-induced cell cycle arrest at G2/M phase in HepG2 cell, during which the expression levels of cyclin B1, CDK1, and p-CDK1 proteins were downregulated, whereas expression of p21 was upregulated in the irradiated HepG2 cells. After irradiation, typical morphological changes of apoptosis in HepG2 cells were observed; the number of cell apoptosis and the expression of apoptosis associated proteins were significantly increased in HepG2 cells by high dose irradiation compared with low dose irradiation. Additionally, compared with low dose irradiation, high dose irradiation significantly downregulated the phosphorylated proteins in the Ras/Raf/MEK/ERK signaling pathway.Conclusions: Our results suggest that irradiation applied in SBRT, particularly single high dose irradiation, mediates its anti-tumor effects by inducing cell cycle arrest and apoptosis via modulation of the Ras/Raf/MEK/ERK signaling pathway.

Abstract
Background The comparative efficacy of epidural bupivacaine alone and bupivacaine combined with magnesium sulfate in providing postoperative analgesia remains controversial. Methods We searched Mediline (OvidSP), EMBASE (OvidSP) and Cochrane Central Register of Controlled Trials (CENTRAL) to identify trials that compared epidural bupivacaine and magnesium sulfate combination (intervention) with bupivacaine alone (control). Grading of Recommendations, Assessment, Development and Evaluations (GRADE) framework was used to assess the quality of evidence. Results Eleven studies fulfilled our inclusion criteria after screening. We found that epidural bupivacaine combined with magnesium sulfate could prolong the time for first rescue analgesics (SMD 4.96; 95% CI [2.75, 7.17], P < 0.00001, I2 = 98%), reduce the number of patients who need rescue analgesics (RR 0.38; 95% CI [0.20, 0.74], P = 0.004, I2 = 75%) and requirement for rescue analgesics (SMD -2.65; 95% CI [− 4.23, − 1.06], P = 0.001, I2 = 96%). Conclusions Magnesium suifate as an adjuvant of epidural bupivacaine improved postoperative analgesia. However, we rated the quality of evidence to be very low because of high heterogeneity, imprecise of results and small sample sizes. Furthermore, further large high-quality trials are still needed to confirm the effects of magnesium sulfate on postoperative analgesia.

Abstract
Sestrin2 (SESN2), a highly evolutionarily conserved protein, is critically involved in cellular responses to various stresses. SESN2 has a protective effect on physiological and pathological states mainly via regulating oxidative stress, endoplasmic reticulum stress, autophagy, metabolism, and inflammation. In recent years, breakthrough investigations with regard to the regulation and signaling mechanisms of SESN2 have markedly deepened our understanding of its potential role as well as its significance in host response. However, the functions of SESN2 in the immune system and inflammation remain elusive. It has been documented that many immune cells positively express SESN2 and, in turn, that SESN2 might modulate cellular activities. This review incorporates recent progress and aims to provide novel insight into the protective role and regulatory pathway of SESN2, which acts as a potential biomarker and therapeutic target in the context of various diseases.

Abstract
The gut is composed of a single layer of intestinal epithelial cells and plays important roles in the digestion and absorption of nutrients, immune and barrier functions and amino acid metabolism. Weaning stress impairs piglet intestinal epithelium structural and functional integrities, which results in reduced feed intake, growth rates and increased morbidity and mortality. Several measures are needed to maintain swine gut development and growth performance after weaning stress. A large body of evidence indicates that, in weaning piglets, glutamine, a functional amino acid, may improve growth performance and intestinal morphology, reduce oxidative damage, stimulate enterocyte proliferation, modulate cell survival and death and enhance intestinal paracellular permeability. This review focuses on the effects of glutamine on intestinal health in piglets. The aim is to provide evidentiary support for using glutamine as a feed additive to alleviate weaning stress.

Abstract
Objective: To investigate pathogenic genes related to the phenotype of fetus with severely short limbs in the first and second trimester by whole exome sequencing (WES). Methods: Thirteen fetuses with severely short limbs detected by ultrasonography in the first and second trimester admitted in Chinese PLA General Hospital from September 2016 to June 2018 were collected. All cases were performed induced abortion, 6 of which were carried out karyotype analysis of amniotic fluid at the same time. WES and copy number variations (CNV) were performed on specimens from fetal tissues after labor induction. The suspected pathogenic mutations were validated by Sanger sequencing reactions. Results: No abnormal karyotypes or pathological CNV were found. In 10 fetuses, pathogenic or possibly pathogenic mutations were detected in the following genes: COL2A1, FGFR3, COL1A1, COL1A2, DYNC2LI1 and TRIP11, all of which were essential to skeletal development. The diagnostic yield of WES in the fetuses with severe short limbs was 10/13. Conclusions: In the first and second trimester, most of the fetuses with extremely short limbs suffer from monogenic diseases. WES is likely to be a valuable diagnostic testing option for the fetuses with severe short limbs.

Abstract
With the accelerating process of population aging in China, social pension system has been rapidly developed, but its service quality remains poor. How to provide quality and efficient elderly care services has become a major livelihood issue of general public. The existing evaluation standards for service quality in the elderly care institutions vary greatly in terms of literature review and practice, and they have only single perspective and lack systematic review. Based on the three-dimensional theory of "structure-process-result" quality evaluation, this paper systematically compares and evaluates the evaluation index system and evaluation management mechanism of service quality of pension institutions in typical countries and regions, and provides an evidence-based basis for establishing an evaluation management system, which is in line with China's national conditions and covers evaluation principles, subject and object, regulation, rewards and punishments, and classifications.

Abstract
Objective: To investigate frailty progress status and related factors in the elderly living in communities. Methods: A cohort of elderly people aged 65 and over in Pingyi community of Dujiangyan, Sichuan province, was established. Face-to-face questionnaire survey was conducted by trained interviewers. The frailty status, cognitive function, nutrition status and other functions of the subjects surveyed were evaluated at baseline survey and during follow-up. The socio-demographic and clinical characteristics of the subjects surveyed were assessed at baseline survey. Binary logistic regressions were used to identify factors associated with frailty progress. Results: A total of 653 elderly people were surveyed in January 2014, and 507 elderly people were followed up while 146 elderly people terminated further follow-up in January 2017. The prevalence rates of frailty and pre-frailty at baseline survey were 11.2% (n=57) and 26.2% (n=133), respectively. After 3 years, 205 subjects (40.4%) surveyed experienced frailty progress, 276 (54.5%) remained to be in frailty state at baseline survey, and 26 (5.1%) had improvement. Disability (OR=8.27, 95%CI: 1.62-42.26), visual problem (OR=2.02, 95%CI: 1.27-3.22), cognitive impairment (OR=1.94, 95%CI: 1.08-3.48), poor self-rated health (OR=1.89, 95%CI: 1.07-3.31), chronic pain (OR=1.57, 95%CI: 1.03-2.40) and older age (OR=1.12, 95%CI: 1.08-1.17) were independently associated with the progress of frailty. In contract, overweight was a protective factor (OR=0.54, 95%CI: 0.34-0.85). Conclusions: Frailty is a dynamic syndrome affected by several socio-demographic factors and geriatric factors. The results of the study can be used in the prevention of frailty progress in the elderly in communities.

Abstract
Objective: To compare and analyze the differentially expressed plasma exosomic proteome between healthy control group (Control group) and viral myocarditis group (VMC group) to search for biomarkers that maybe used for early diagnosis of VMC. Methods: Fifty plasma samples of Control group and VMC group were collected respectively from Henan Provincial People's Hospital (from January 2016 to December 2017), and then 5 samples (1 ml) of each group were selected randomly, after exosomes extraction with ultra-centrifugation, difference gel electrophoresis (DIGE) was used to isolate the total proteins, and then the protein spots with more than 2-fold changes between VMC and Control group were picked up after the software analysis, afterward, the varied proteins were identified by MALDI-TOF/TOF mass spectrometry. Finally, the specifically related protein was selected to be verified by ELISA with the plasma exosomic samples of Control (n=40) and VMC (n=40). Results: A total of 10 varied protein spots were found including 8 up-regulated proteins and 2 down-regulated proteins between VMC and Control group. After MS analysis, the up-regulated proteins in VMC group contained KRT2, KRT5, KRT9, KRT77, KRT78, AZGP1, HP and RBP4, whereas the down-regulated ones were CD5L and C1QB. RBP4 was selected to validate by ELISA analysis, and the corresponding results showed that RBP4 was increased specifically in plasma exosomes of VMC group (P<0.05) after comparing with Control group, which was consistent with DIGE. Conclusion: Ten proteins related to VMC are detected in total, and RBP4 might serve as a potential specific biomarker for early screening and diagnosis of VMC.

Abstract
Objective: To compare and analyze the epidemiological characteristics of hospitalized elderly, young and middle-aged patients with severe burn in recent years, so as to provide reference for the prevention and treatment of elderly patients with severe burn. Methods: Relying on the entry system of epidemiological case data and biological sample of severe burn from multicenter in clinic, medical records of patients with severe burn, aged above 18, hospitalized in 8 burn wards from January 2012 to December 2015 were collected. Six hundred and fifteen patients who were more than 18 years old and less than or equal to 65 years old were included in young and middle-aged group (YM). Eighty-two patients aged more than 65 years old were included in elderly group (E). Data of age, gender, residence, education level, cause of injury, location of injury, season of injury, total burn area, occurrence and area of full-thickness burn injury, wound site, inhalation injury incidence and severity, post burn admission time, proportion of delayed resuscitation, proportion of escharectomy or tangential excision and skin grafting, preinjury systemic disease, system complication during hospitalization, length of hospital stay, outcome of treatment, and reason of abandoning treatment of patients were analyzed. Data were processed with chi-square test and Mann-Whitney U test. The odds ratios of preinjury systemic disease, system complication during hospitalization, and adverse outcome of patients in group YM were compared with those in group E. Results: (1) The majority of patients in the two groups were male, but the proportion of male patients in group YM was higher. There was statistically significant difference in gender distribution of patients between the two groups (χ(2)=18.727, P<0.001). The majority of patients in the two groups were from rural areas, but the proportion of rural patients in group E was higher. There was statistically significant difference in residence distribution of patients between the two groups (χ(2)=9.306, P=0.002). Patients in group YM mainly had secondary education, while patients in group E mainly had primary education. There was statistically significant difference in distribution of education level of patients between the two groups (χ(2)=146.797, P<0.001). (2) The most common causes of injury of patients in the two groups were both flame, but the proportion of patients with flame burn injury in group E was higher. There was statistically significant difference in distribution of cause of injury of patients between the two groups (χ(2)=25.063, P<0.001). The main locations of injury of patients in groups YM and E were respectively public place and private residence. There was statistically significant difference in location distribution of injury of patients between the two groups (χ(2)=46.313, P<0.001). The main seasons of injury of patients in groups YM and E were respectively summer and winter. There was statistically significant difference in season distribution of patients between the two groups (χ(2)=23.143, P<0.001). There was statistically significant difference in distribution of total burn area of patients between the two groups (χ(2)=25.799, P=0.002). The occurrences of full-thickness burn injury of patients in the two groups were similar (χ(2)=2.685, P=0.101), while there was statistically significant difference in area of full-thickness burn injury of patients between the two groups (χ(2)=26.702, P=0.002). There was no statistically significant difference in distribution of wound site of patients between the two groups (χ(2)=3.954, P=0.785). There were no statistically significant differences in incidence and severity distribution of inhalation injury of patients between the two groups (with χ(2) values respectively 0.425 and 0.672, P values above 0.05). (3) There was statistically significant difference in distribution of admission time of patients between the two groups (χ(2)=6.632, P=0.036), but there was no statistically significant difference in proportion of delayed resuscitation of patients between the two groups (χ(2)=1.261, P=0.261). The proportion of escharectomy or tangential excision and skin grafting of patients in group YM was 72.0% (443/615), which was significantly higher than 35.4% (29/82) of group E (χ(2)=44.498, P<0.001). The incidence of preinjury systemic disease of patients in group YM was 13.2% (81/615), which was significantly lower than 61.0% (50/82) of group E (χ(2)=108.337, P<0.001). The risk of preinjury systemic disease of patients in group E was 10.30 times of that of patients in group YM [with 95% confidence interval (CI) of 6.24-17.01, P<0.001]. During hospitalization, 59.8% (49/82) of patients in group E suffered from system complications, which was significantly higher than 36.6% (225/615) of group YM (χ(2)=16.282, P<0.001). The risk of system complication of patients in group E was 2.57 times of patients in group YM (with 95% CI of 1.61-4.12, P<0.001). The length of hospital stay of patients in group E was significantly shorter than that of group YM (U=36 735, P<0.001). There was statistically significant difference in treatment outcome of patients between the two groups (χ(2)=106.251, P<0.001). The risk of adverse outcome of patients in group E was 7.52 times of group YM (with 95% CI of 4.40-12.88, χ(2)=67.709, P<0.001). The proportion of abandoning treatment of patients in group E was significantly higher than that of group YM (χ(2)=150.670, P<0.001). The risk of abandoning treatment of patients in group E was 15.86 times of that of group YM (with 95% CI of 9.36-26.88, P<0.001). There was no statistically significant difference in distribution of reason of abandoning treatment of patients between the two groups (χ(2)=4.178, P=0.243). Conclusions: There were significant differences in the epidemiological characteristics of patients in groups E and YM. In elderly burn patients, the proportion of rural population was higher and the education level was lower. Flame burn was common and burns mostly occurred in private residences and in winter. The total burn area was slightly lower but the area of full-thickness burn injury was larger. The length of hospital stay was shorter and the proportion of surgical treatment was lower. The incidences of preinjury systemic disease and system complication during hospitalization were higher, and therefore the risks of adverse outcome and abandoning treatment were higher.

Abstract
Objective: To investigate the levels of lanthanum, cerium, praseodymium, and neodymium in the blood, urine, and hair samples from residents in the rare earth mining area of a city in China, and to provide a scientific basis for the control of rare earth pollution and the protection of population health. Methods: A total of 147 residents who had lived in the rare earth mining area of a city for a long time were selected as the exposure group, and 108 residents in Guyang County of this city who lived 91 km away from the rare earth mining area were selected as the control group. Blood, urine, and hair samples were collected from the residents in both groups. Inductively coupled plasma mass spectrometry was used to determine the content of lanthanum, cerium, praseodymium, and neodymium in blood, urine, and hair samples. Results: In the exposure group, the median levels of lanthanum, cerium, praseodymium, and neodymium were 0.854, 1.724, 0.132, and 0.839 μg/L, respectively, in blood samples, 0.420, 0.920, 0.055, and 0.337 μg/L, respectively, in urine samples, and 0.052, 0.106, 0.012, and 0.045 μg/g, respectively, in hair samples. The exposure group had significantly higher levels of the four rare earth elements in blood, urine, and hair samples than the control group (P<0.01) . Conclusion: The residents in the rare earth mining area of this city have higher content of lanthanum, cerium, praseodymium, and neodymium in blood, urine, and hair than those in the non-mining area; the content of cerium is highest, followed by lanthanum, neodymium, and praseodymium.

Abstract
Objective: To explore nerve fiber regeneration and subjective visual quality of patients undergoing small incision lenticule extraction (SMILE) surgery, femtosecond laser-assisted in-situ keratomileusis (FS-LASIK) and transepithelial photorefractive keratectomy (T-PRK), and study their correlation. Methods: This is a prospective cohort study including 55 patients (6 male, 49 female, age 25.6±7.3, in total 109 eyes) who chose refractive surgery in Peking Union Medical College Hospital. They are subdivided into 3 groups: 35 patients in SMILE (4 male, 31 female), 9 patients in FS-LASIK (1 male, 8 female) and 11 patients in T-PRK (1 male, 10 female). All surgeries were conducted by the same surgeon. Patients underwent confocal microscopy examinations and filled in subjective visual quality questionnaires before surgery and 7 days, 30 days and 90 days after surgery. ACCMterics V.2 was used for nerve analysis. One-way analysis of variance, Kruskal-Wallis H test and Pearson correlation study was adopted for data analysis on SPSS 22.0. Results: Corneal nerve fiber density is lowest at 7 days after surgery. The nerve fiber length (8.53 (7.32), 9.33 (6.47), 10.98 (4.85) mm/mm(2), χ(2)=9.21, 8.15, 6.54; P<0.05), density (12.50 (12.50), 12.50 (12.50), 18.75 (14.06)/mm(2), χ(2)=6.54, 9.02, 7.01; P<0.05) and total branch density (18.75 (31.25), 24.99 (29.69), 31.25 (32.81)/mm(2), χ(2)=10.23, 7.63, 10.01; P<0.05) of SMILE group are significantly higher than the other 2 groups at 7 days, 30 days and 90 days after surgery. The subjective visual quality scores are (4.13±0.61), (3.54±0.71), (4.03±0.70) and (4.20±0.58) respectively at each visit, with 7 days being the lowest (F=1.51, P=0.23), but there is no statistically significant difference between each group at each visit. At 7 days after surgery, the nerve fiber length (CNFL) and nerve fiber density (CNBD) show strong positive correlation with overall subjective visual quality (r=0.378, 0.504; P<0.05), while there exists no significant correlation between nerve fiber parameters and subjective visual quality 30 days and 90 days after surgery. Conclusions: SMILE shows better results in corneal nerve fiber regeneration. Corneal nerve fiber density of early post-operational period is positively correlated with overall subjective visual quality. (Chin J Ophthalmol, 2018, 54: 737-743).

Abstract
Sepsis remains the leading cause of high mortality and huge financial burden in intensive care units (ICU), but with scarce effective treatments due to refractory multiple organ dysfunction and persistent immunosuppression. Treatments that aim at modulating immune function and attenuating multiple organ injury will certainly benefit septic cases. Alpha 7 nicotinic acetylcholine receptor (α7nAchR) has been reported with potent immunomodulatory properties in various diseases as the essential mediator of the cholinergic anti-inflammatory pathway (CAP). Few studies have demonstrated the potential effect of central α7nAchR on the progression and prognosis of septic response, while its expression was first discovered on neurons and most abundant in the central nervous system. In the present study, it was found severe damage of multiple organs under the operation of cecal ligation and puncture (CLP) in rats, including heart, liver, kidneys, and lungs, as evidenced by abnormal histomorphology and notable elevation of injury markers. Concurrently, the function of spleen CD4+ T cells was disrupted under septic challenge, accompanied by polarization of helper T cell (Th)2, which exhibited outward signs of immunosuppression. Intracerebroventricular injection of PNU282987, a selective agonist of α7nAchR, significantly alleviated multiple organ injury, reversed immunosuppressive state, and improved the outcome of septic rats, while they were exacerbated by treatment with methyllycaconitine, a selective antagonist of α7nAchR. This study provides the first evidence that activation of central α7nAchR is beneficial for attenuating multiple organ dysfunction as well as abnormal immune response, and improving the prognosis of rats when exposed with sepsis.

Abstract
Objective: To analyze the spatial and temporal clustering characteristics of typhoid and paratyphoid fever and its change pattern in Yunnan, Guizhou and Guangxi provinces in southwestern China in recent years. Methods: The incidence data of typhoid and paratyphoid fever cases at county level in 3 provinces during 2001-2012 were collected from China Information System for Diseases Control and Prevention and analyzed by the methods of descriptive epidemiology and geographic informatics. And the map showing the spatial and temporal clustering characters of typhoid and paratyphoid fever cases in three provinces was drawn. SaTScan statistics was used to identify the typhoid and paratyphoid fever clustering areas of three provinces in each year from 2001 to 2012. Results: During the study period, the reported cases of typhoid and paratyphoid fever declined with year. The reported incidence decreased from 30.15 per 100 000 in 2001 to 10.83 per 100 000 in 2006(annual incidence 21.12 per 100 000); while during 2007-2012, the incidence became stable, ranging from 4.75 per 100 000 to 6.83 per 100 000 (annual incidence 5.73 per 100 000). The seasonal variation of the incidence was consistent in three provinces, with majority of cases occurred in summer and autumn. The spatial and temporal clustering of typhoid and paratyphoid fever was demonstrated by the incidence map. Most high-incidence counties were located in a zonal area extending from Yuxi of Yunnan to Guiyang of Guizhou, but were concentrated in Guilin in Guangxi. Temporal and spatial scan statistics identified the positional shifting of class Ⅰ clustering area from Guizhou to Yunnan. Class Ⅰ clustering area was located around the central and western areas (Zunyi and Anshun) of Guizhou during 2001-2003, and moved to the central area of Yunnan during 2004-2012. Conclusion: Spatial and temporal clustering of typhoid and paratyphoid fever existed in the endemic areas of southwestern China, and the clustering area covered a zone connecting the central areas of Guizhou and Yunnan. From 2004 to 2012, the most important clustering area shifted from Guizhou to Yunnan. Findings from this study provided evidence for the identifying key areas for typhoid and paratyphoid fever control and prevention and allocate health resources.

Abstract
Background The primary pulmonary lymphoma (PPL), with a low incidence, was highly misdiagnosed in clinic. The present study analyzes the clinical features, laboratory and imaging data, pathologic characteristics, and summarizes misdiagnosis reasons of PPL cases, aims to provide a better understanding and increase the accuracy of early diagnosis and minimize the misdiagnosis of PPL. Methods The clinical data of 19 cases were collected from the first affiliated hospital of Wenzhou medical university (PRC) from April 2010 to May 2016. All cases were confirmed by pathology. The process of misdiagnosis was described. This study retrospectively analyzed the incidence, clinical presentation, laboratory examination, Chest CT scan and diagnosis of the cases. Results The symptoms of the 19 cases were dyspnea, fever, hemoptysis, chest pain or physical findings without obvious symptoms. Five patients were pneumonia-like, nine patients had lung single nodule or mass and four patients got pleural effusion, which were reported by computed tomography (HRCT) scan. There were 2 cases of Hodgkin lymphoma (HL), and 17 cases of non-Hodgkin lymphoma (NHL). In NHL cases, 12 cases were confirmed mucosa associated lymphoid tissue B lymphoma type, 3 cases were confirmed diffuse large B-cell lymphoma, angioimmunoblastic T-cell lymphoma and ALK positive anaplastic large cell lymphoma were one case separately. Clinical and imaging manifestation of PPL is untypical, but there are still some hints: 1) Fuzzy shadow at the edge of lung mass with air bronchogram; 2) Lung mass shadow stable for a long time; 3) Pneumonia-like changing without infections clinical and lab manifestation. Thirteen patients (68.4%) were misdiagnosed as pneumonia, lung cancer and tuberculosis initially. The term between initial diagnosis and final diagnosis lasted for half a month up to 2 years, with median time of 6 months. Two cases were misdiagnosed as tuberculosis. One case was misdiagnosed as small cell lung cancer. Conclusion Clinical and imaging manifestation of PPL is untypical. Biopsies should be taken actively if the imaging findings don’t match the symptoms or the anti-infection treatments to “lung infection” don’t work. Accurate diagnosis requires adequate tissue sampling with appropriate ancillary pathologic studies. If clinical manifestation and the diagnosis don’t match, repeated biopsy should be ordered.

Abstract
OBJECTIVE To explore the surgical strategies for the treatment of T1b gallbladder cancer patients diagnosed intraoperatively or postoperatively. METHODS A retrospective analysis of 42 patients with T1b gallbladder cancers was performed. There were 14 patients diagnosed intraoperatively and 28 patients diagnosed postoperatively. The reevaluations of T stages were conducted in the 28 T1b gallbladder cancer patients diagnosed postoperatively by the professional pathologist. After T stage reevaluation, 25 confirmed T1b patients with complete follow-up data were divided into simple cholecystectomy group and ra-dical resection group, and the clinicopathologic characteristics between the two groups were analyzed. RESULTS Only 2 of the 14 T1b gallbladder cancer patients diagnosed by the intraoperative frozen specimen proved to be T1b on postoperative paraffin pathology, and for the remaining 13 patients, T2 was in 11 patients, and T3 in one patient. The rate of misdiagnosis was 85.7% by the intraoperative frozen specimens, postoperative T stages were equal or higher than intraoperative T stages. Two of the 28 postoperatively diagnosed T1b patients were proved to be T2 after reevaluation, the rate of misdiagnosis was 7.1%, the reevaluated T stages were equal to or higher than the previous stages. Twenty-five confirmed T1b gallbladder cancer patients had complete follow-up data, 11 of whom underwent simple cholecystectomy and the remaining 14 radical resections. No patient had vessel or perineural invasion on pathology in the 25 confirmed T1b patients. Metastasis was absent in all the 30 lymph nodes examined, which achieved from 14 patients with radical resection. The survival rate after simple cholecystectomy was comparable to that after radical resection (P=0.361). Only one patient with radical resection had abdominal cavity implantation relapse, who received gallbladder compression during operation and 2 years later died from metastasis. CONCLUSION Intraoperatively diagnosed T1b gallbladder cancer should receive radical resection. Reevaluation of the T stage is necessary and the initial step for postoperative diagnosed T1b gallbladder cancer patients. The pros and cons of radical surgery for definitive T1b patients should be carefully evaluated, and systemic chemotherapy is recommended for those with bile spillover.

Abstract
Objective To investigate whether sustained abdominal aorta compression (SAAC) can improve coronary perfusion pressure (CPP) during cardiopulmonary resuscitation (CPR) and improve resuscitation outcomes without causing liver laceration. Design and Setting Animal study. Methods Cardiac arrest was induced by asphyxia in 28 New Zealand rabbits and maintained for 2 minutes before resuscitation. Animals were resuscitated using either standard CPR (STD-CPR group) or standard CPR and SAAC (SAAC-CPR group). Restoration of spontaneous circulation (ROSC), restoration of spontaneous breathing (ROSB) and cerebral performance category score were determined. CPP, mean arterial pressure (MAP) and ROSC were compared in the two groups. Results MAP and CPP in the SAAC-CPR group were significantly higher than in the STD-CPR group. However, MAP and blood gas results showed no significant difference between the two groups during ROSC. ROSC was achieved in seven of fourteen animals in the STD-CPR group and in eleven of fourteen animals in the SAAC-CPR group. Five animals in the STD-CPR group and nine in the SAAC-CPR group survived 24 hours after ROSC. No liver injury occurred in the two groups. Conclusions SAAC-CPR produces an increased CPP and MAP than traditional CPR and it does not lead to liver laceration/injury.
