Abstract
Heat stroke (HS) is an acute physical illness associated with a higher risk of organ dysfunction. This study is the first to explore exosomal miR-548x-3p derived from human bone marrow mesenchymal stem cells (BMSCs) in the pyroptosis of vascular endothelial cells (VECs) associated with HS. Human BMSCs-derived exosome alleviated the injury of the heart, liver, kidney and ileum tissues, the increase of IL-1β, IL-18 and TNF-α levels, pyroptosis of endothelial cells and the increase of HGMB1, NLRP3, ASC, caspase1 and GSDMD-N protein expression in HS mice and HS-induced human umbilical vein endothelial cells (HUVECs). miR-548x-3p was down-expressed in HS patients, while up-expressed in BMSCs-derived exosome. BMSCs-ExomiR-548x-3p mimics to inhibit pyroptosis, inflammation and HGMB1/NLRP3 activation in HS-induced HUVECs and HS mice, which were blocked by overexpression of HMGB1. In conclusion, human BMSCs-derived exosomes carried miR-548x-3p mimics to inhibit pyroptosis of VECs through HMGB1 in HS mice.

Abstract
PURPOSE/OBJECTIVE(S) Thoracic irradiation involves large blood vessels and hematopoietic tissues which was easily inducing lymphopenia. Lymphocytes are important components of immune response and lymphopenia is associated with poorer survival. However, the dynamic recovery of lymphocyte subsets after thoracic irradiation were rarely reported in the literature. This study focused on dynamic changes of lymphocytes subsets of mice after receiving thoracic irradiation in and out of radiation field. MATERIALS/METHODS C57BL/6 male mice aged 6-8 weeks received 2Gy*5fx whole thoracic irradiation and were sacrificed on the 1 day, 7 days, 15 days, 25 days after irradiation. Peripheral blood was harvested for mature lymphocyte subsets (B cells, T cells, CD4+T cells, CD8+T cells, NK cells) detection by performing flow cytometry, while thymus, femur bone marrow and sternal bone marrow for hematopoietic stem cells (Long-term Hematopoietic Stem Cell [LT-HSC], Short-term Hematopoietic Stem Cell [ST-HSC]) and progenitor cells (Multipotent Progenitor [MPP], Common Lymphoid Progenitor [CLP]). Absolute counts method was used in flow cytometry and data analysis were performed by scientific 2-D graphing and statistics software. RESULTS We found that the lymphocyte subsets were significantly reduced in peripheral blood of irradiated mice (all p<0.05). The mature lymphocyte subsets returned to normal 2-3 weeks after irradiation. After radiation, thymus weight was significantly decreased (p<0.0001). With the recovery of thymus weight, the number of hematopoietic stem cells returned to the baseline. For the femur bone marrow (out of the radiation field), hematopoietic stem cells and progenitor cells showed a proliferation tendency. MPP significantly increased in the 1day after irradiation (p = 0.0347) and LT-HSC increased in the 8 days (p = 0.0011). However, although ST-HSC and CLP were slightly increased after irradiation, there were no statistically significance. The sternal bone marrow (in the radiation field) reached the lowest value 1day after irradiation (all p<0.0001). Although hematopoietic stem cells and progenitor cells recovered gradually, but still far away from the level of the control group (all p<0.05). CONCLUSION The recovery of lymphocytes in the peripheral blood might mainly come from the supplement of bone marrow out of the irradiation field, while bone marrow in the field suffered serious destruction which did slightly help for lymphocytes recovery.

Abstract
PURPOSE/OBJECTIVE(S) Lymphocytes play a critical role in anti-tumor, and are highly sensitive to radiation. However, the dynamic changes of lymphocytes subsets after receiving thoracic radiotherapy have rarely been investigated. This study was to explore the recovery characteristics of each subset, and the role of thymosin α1 after thoracic radiotherapy. MATERIALS/METHODS A total of 252 patients receiving chest radiotherapy included in this study. Blood was harvested before, at the end of radiotherapy, 1 month, 4 months, 7 months, 10 months, 13 months, and 19 months after radiotherapy for lymphocyte subsets detection by performing flow cytometry. In addition, a total of 26 patients with thoracic malignancy were treated with thymosin α1 after radiotherapy for one month. The number of lymphocyte subsets at the end of 1 month after radiotherapy were compared with control group. Absolute counts method was used in flow cytometry. RESULTS At the end of radiotherapy, nearly all of the subsets decreased significantly (T cell: 65.4%, Tc cell: 64.8%, Th cell: 66.1%, B cell: 88.7%, NK cell: 68.8%), except Treg cell. Tc cells recovered rapidly to baseline level at 1 month. The number of NK cells increased by 1.95 times at 1 month, and recovered to baseline level at 7th month. The number of B cell at 1 month was still 19.2% compared baseline, and recovered slowly to baseline at 7th month. The number of Th cells were nearly no recovery, and were 44.1% compared with baseline even at 19th month. For patients with thymosin α1 injection, all of the lymphocyte subsets had no significant difference compared those without thymosin α1 injection. In addition, younger patients were with better recovery in Th cells (p = 0.011) and B cells (p < 0.001) than elder patients at 1 month. CONCLUSION B cell was the most radiosensitive lymphocyte, and Th cell was continuous exhaustion after thoracic radiation. Thymosin α1 had no effect on lymphocyte subpopulation recovery, and new drugs are urgently needed to explore in the future.

Abstract
BACKGROUND Despite the prolonged median disease-free survival (DFS) by adjuvant targeted therapy in non-small-cell lung cancer patients with epidermal growth factor receptor (EGFR) mutations, the relationship between the treatment duration and the survival benefits in patients remains unknown. PATIENTS AND METHODS In this multicenter, randomized, open-label, phase II trial, eligible patients aged 18-75 years with EGFR-mutant, stage II-IIIA lung adenocarcinoma and who had not received adjuvant chemotherapy after complete tumor resection were enrolled from eight centers in China. Patients were randomly assigned (1 : 1) to receive either 1-year or 2-year icotinib (125 mg thrice daily). The primary endpoint was DFS assessed by investigator. The secondary endpoints were overall survival (OS) and safety. This study was registered at ClinicalTrials.gov (NCT01929200). RESULTS Between September 2013 and October 2018, 109 patients were enrolled (1-year group, n = 55; 2-year group, n = 54). Median DFS was 48.9 months [95% confidence interval (CI) 33.1-70.1 months] in the 2-year group and 32.9 months (95% CI 26.6-44.8 months) in the 1-year group [hazard ratio (HR) 0.51; 95% CI 0.28-0.94; P = 0.0290]. Median OS for patients was 75.8 months [95% CI 64.4 months-not evaluable (NE)] in the 2-year group and NE (95% CI 66.3 months-NE) in the 1-year group (HR 0.34; 95% CI 0.13-0.95; P = 0.0317). Treatment-related adverse events (TRAEs) were observed in 41 of 55 (75%) patients in the 1-year group and in 36 of 54 (67%) patients in the 2-year group. Grade 3-4 TRAEs occurred in 4 of 55 (7%) patients in the 1-year group and in 3 of 54 (6%) patients in the 2-year group. No treatment-related deaths or interstitial lung disease was reported. CONCLUSIONS Two-year adjuvant icotinib was shown to significantly improve DFS and provide an OS benefit in EGFR-mutant, stage II-IIIA lung adenocarcinoma patients compared with 1-year treatment in this exploratory phase II study.

Abstract
OBJECTIVE Changes in hormone levels, improper lipid metabolism, and oxidative stress all significantly contribute to the pathogenic process of polycystic ovarian syndrome (PCOS). According to earlier research, pioglitazone and alpha-lipoic acid are crucial in the emergence of PCOS. The beneficial effects of pioglitazone and alpha-lipoic acid on PCOS were examined in the current study. PATIENTS AND METHODS The 120 patients with PCOS received three months of treatment in pioglitazone groups (n=40 case, 30 mg/time, 1 time/day), α-lipoic acid (n=40 case, 0.6 g/time, 1 time/day), and combination therapy (n=40 case, pioglitazone 30 mg/time, 1 time/day and α-lipoic acid, 0.6 g/time, 1 time/day). Before and after therapy, the following factors were evaluated: the hormonal profile, fasting serum insulin, body weight, body mass index (BMI), menstruation status, oxidative stress, and indications of lipid metabolism. RESULTS The combination of pioglitazone and α-lipoic acid has a significantly improving effect on BMI, body weight, oxidative stress levels, lipid metabolism, and menstrual status. A significant increase in body weight, BMI, and follicle-stimulating hormone (FSH) levels were found in mice after being treated with α-lipoic acid alone. However, the use pioglitazone alone improves body weight, BMI, the calculation of insulin resistance index (HOMA-IR), Area under the curve (AUC)-insulin, fasting glucose/insulin (G/I) ratio, total testosterone, and malondialdehyde (MDA) levels in post-treatment than pre-treatment. CONCLUSIONS These findings suggest that pioglitazone alone has a better effect than alpha-lipoic acid in improving oxidative stress levels, BMI, and menstrual cyclicity. Additionally, treatment with pioglitazone and alpha-lipoic acid did demonstrate a greater effect than monotherapy with each medication alone.

Abstract
OBJECTIVE Sepsis is a life-threatening condition secondary to infection that evolves into a dysregulated host response and is associated with acute organ dysfunction. Sepsis-induced cardiac dysfunction is one of the most complex organ failures to characterize. This study performed comprehensive metabolomic profiling that distinguished between septic patients with and without cardiac dysfunction. METHOD Plasma samples collected from 80 septic patients were analysed by untargeted liquid chromatography-mass spectrometry (LC-MS) metabolomics. Principal component analysis (PCA), partial least squares discrimination analysis (PLS-DA), and orthogonal partial least square discriminant analysis (OPLS-DA) were applied to analyse the metabolic model between septic patients with and without cardiac dysfunction. The screening criteria for potential candidate metabolites were as follows: variable importance in the projection (VIP) >1, P < 0.05, and fold change (FC) > 1.5 or < 0.7. Pathway enrichment analysis further revealed associated metabolic pathways. In addition, we constructed a subgroup metabolic analysis between the survivors and non-survivors according to 28-day mortality in the cardiac dysfunction group. RESULTS Two metabolite markers, kynurenic acid and gluconolactone, could distinguish the cardiac dysfunction group from the normal cardiac function group. Two metabolites, kynurenic acid and galactitol, could distinguish survivors and non-survivors in the subgroup analysis. Kynurenic acid is a common differential metabolite that could be used as a candidate for both diagnosis and prognosis for septic patients with cardiac dysfunction. The main associated pathways were amino acid metabolism, glucose metabolism and bile acid metabolism. CONCLUSION Metabolomic technology could be a promising approach for identifying diagnostic and prognostic biomarkers of sepsis-induced cardiac dysfunction.

Abstract
Recently, accumulating evidence has shown that hydrogen sulphide (H2 S), a newly determined gasotransmitter, plays important roles in senescence, which is an essential biological process for plant fitness and an important agricultural trait that is critical for the yield and quality of farm produce. Here, in this review, we summarize the roles of H2 S in senescence, both before and after the harvesting of agricultural products, and the underlying mechanism is also discussed. During the plant growth process, the function of H2 S in the leaf senescence process has been studied extensively, and H2 S plays roles during the whole process, including the initiation, reorganization and terminal stages. While during the postharvest stage, H2 S can prevents farm products from deterioration resulting from over-ripening, pathogen attack and incorrect storage. The underlying H2 S-related mechanisms during different stages of the senescence process are summarized and compared. The most prominent interaction occurs between H2 S and reactive oxygen species, and the molecular mechanism is explored. Additionally, the conserved action mode of H2 S in different life processes and different species is also discussed. In the future, multi-omics analyses over time will be needed to investigate the detailed mechanisms of H2 S, and a safety attribute analysis of H2 S is also required before it can be used in agricultural production.

Abstract
OBJECTIVE Sepsis is the leading course of morbidity and mortality in critically ill patients. This study aimed to evaluate the predictive value of the platelet aggregation for mortality in patients with sepsis. In addition, the relationship between impaired mitochondria and the platelet aggregation was explored. METHOD This was a prospective, observational cohort study. The platelet aggregation rate in response to adenosine diphosphate (ADP) was assessed. The primary outcome was 28-day mortality. Platelet mitochondrial parameters, including adenosine triphosphate(ATP), mitochondrial membrane potential (MMP) and mitochondrial permeability transition pore (mPTP) opening, were measured. Platelet mitochondrial ultrastructure was observed using transmission electron microscopy. RESULTS 86 patients with 65 survivors and 21 non-survivors were enrolled. Platelets of non-survivors with sepsis were hyporesponsive to ADP, in terms of maximal aggregation rate (P < 0.001). Receiver operating characteristic curves analysis demonstrated that the AUC estimated 28-day mortality for platelet aggregation rate was 0.814. At the optimal cut-off value of 35.8% for platelet aggregation rate, the sensitivity was 86.2% and the specificity was 66.7%. Kaplan-Meier analysis showed that a platelet aggregation rate of less than 35.8% was associated closely with poor survival. After adjusting for lactate by Cox regression analysis, platelet aggregation rate was identified as an independent predictor for the probability of 28-day mortality. Compared with survivors, non-survivors showed a significant reduction in platelet ATP and MMP-index (both P < 0.001), and a remarkable increase in mPTP opening (P < 0.001). ATP and MMP-index were positively correlated with platelet aggregation rate (R square=0.75, R square=0.44, respectively). CONCLUSION Platelet aggregation rate could be an early predictive biomarker for mortality in sepsis. Impaired platelet mitochondrial activity affects platelet aggregation and correlates with the severity of sepsis.

Abstract
Objective: To provide insight into the diagnosis for clinicians, the clinical characteristics, diagnosis and treatment history of 3 patients with 21-hydroxylase deficiency (21-OHD) and testicular adrenal rest tumors (TART) were analyzed. Methods: The clinical, laboratory and imaging data of 3 male patients with 21-OHD and TART, confirmed with CYP21 gene sequencing, from May 2010 to May 2021 in the First Medical Center of Chinese PLA General Hospital were analyzed retrospectively. The treatment strategy and clinical outcome were followed up. Results: All the 3 patients were first diagnosed with bilateral adrenal mass at the age of 27-42 years old. They were 145-162 cm tall. The levels of progesterone, 17-hydroxyprogesterone, and adrenocorticotropic hormone (ACTH) of the 3 patients were relatively high, and that of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) of the 3 patients were low. Testosterone level of 1 patient was significantly elevated, and that of the other 2 patients was below the lower limit of normal range. Testicular ultrasound showed heterogeneous hyperechoic masses in both testes. CT of the adrenal glands showed bilateral adrenal enlargement with mass. All 3 patients were treated with dexamethasone. After 4-96 months of follow-up, 17-hydroxyprogesterone level was kept above the median normal level. One of the patients got married and had a baby after treatment. The sizes of adrenal hyperplasia and testicular masses reduced to various degrees with the change of the testicular masses being proportional to that of adrenal hyperplasia. Conclusions: Patients with 21-OHD are prone to have TART, leading to the impaired testicular function. Early glucocorticold therapy is beneficial to the reduction of TART and restoration of testicular function.

Abstract
Ginsenoside-Rg1 (G-Rg1), a saponin that is a primary component of ginseng, is effective against inflammatory diseases. The P2X purinoceptor 7 (P2X7) receptor is an ATP-gated ion channel that is predominantly expressed in immune cells and plays a key role in inflammatory processes. We investigated the role of G-Rg1 in sepsis-related cardiac dysfunction and the underlying mechanism involving the regulation of the P2X7 receptor. We detected cell viability, cytotoxicity, cellular reactive oxygen species (ROS) levels, and mitochondrial membrane potential (MMP) with or without G-Rg1 in lipopolysaccharide (LPS)- or hypoxia/reoxygenation (H/R)-induced H9c2 cell models of ischemia/reperfusion injury. We applied cecal ligation and puncture (CLP) to induce a mouse model of sepsis and measured the survival duration and cardiac function of CLP mice. Next, we quantified the ROS level, MMP, respiratory chain complex I-IV enzymatic activity, and mitochondrial fusion in CLP mouse heart tissues. We then investigated the role of G-Rg1 in repairing LPS-induced cell mitochondrial damage, including mitochondrial superoxidation products. The results showed that G-Rg1 inhibited LPS- or H/R-induced cardiomyocyte apoptosis, cytotoxicity, ROS levels, and mitochondrial damage. In addition, G-Rg1 prolonged the survival time of CLP mice. G-Rg1 attenuated LPS-induced superoxide production in the mitochondria of cardiomyocytes and the excessive release of cytochrome c from mitochondria into the cytoplasm. Most importantly, G-Rg1 suppressed LPS-mediated induction of proapoptotic Bax, activated Akt, induced GSK-3β phosphorylation, and balanced mitochondrial calcium levels. Overall, G-Rg1 activates the Akt/GSK-3β pathway through P2X7 receptors to inhibit sepsis-induced cardiac dysfunction and mitochondrial dysfunction.

Abstract
The intestine is one of the main target organs involved in the pathological process of heatstroke. CCAAT/enhancer-binding protein homologous protein (CHOP) is involved in endoplasmic reticulum (ER) stress-induced apoptosis. This study aimed to explore the role of CHOP in heatstroke-induced intestinal injury and potential therapy. An in vitro heat stress (HS) model using Caco-2 cells was employed. We observed the role of CHOP in apoptosis-mediated intestinal epithelial cell injury secondary to HS by evaluating cell viability, lactate dehydrogenase release, apoptosis levels, and GRP78, PERK, ATF4, CHOP, Bcl-2, and BAX mRNA and protein expression. To further study the role of CHOP in HS-induced intestinal barrier dysfunction, we assessed transepithelial electrical resistance, paracellular tracer flux, ultrastructure of tight junctions, and protein expression of ZO-1 and occludin. Male wild-type mice and CHOP knockout mice were used for in vivo experiments. We evaluated serum d-lactate and diamine oxidase levels, histopathological changes, intestinal ultrastructure, and ZO-1 and occludin protein expression. HS activated the PERK-CHOP pathway and promoted apoptosis by upregulating BAX and downregulating Bcl-2; these effects were prevented by CHOP silencing. Intestinal epithelial barrier function was disrupted by HS in vitro and in vivo. CHOP silencing prevented intestinal barrier dysfunction in Caco-2 cells, whereas CHOP knockout mice exhibited decreased intestinal mucosal injury. The ER stress inhibitor 4-phenylbutyrate (4-PBA) prevented HS-induced intestinal injury in vitro and in vivo. This study indicated that CHOP deficiency attenuates heatstroke-induced intestinal injury and may contribute to the identification of a novel therapy against heatstroke associated with the ER stress pathway.

Abstract
The aim of this study was to develop an integrative framework on aging, immigration, and oral health. The methodology was a critical review that used immigration as a social determinant framework through which to evaluate its impact on the oral health of older immigrants. We reviewed recent empirical evidence on factors related to oral health in older immigrants. In a systematic search across multiple databases, we identified 12 eligible studies in this review. Among the eligible studies, most were conducted among East Asian immigrants (8 articles), followed by non-Hispanic White/European origin (2 articles), Mexican origins (1 article), and Iran and other Middle East regions (1 article). The research revealed knowledge gaps in the evidence base, including the dynamic relationship between acculturation and oral health, the role of environmental factors on oral health for immigrants, psychosocial stressors and their relationship with oral health, and oral health literacy, norms, and attitude to dental care utilization and oral hygiene practices. The development of the integrative framework suggests the pathways/mechanisms through which immigration exerts influences on oral health in later life. This provides opportunities for researchers, practitioners, and policy makers to gain greater insights into the complex associations between immigration and oral health among older adults.

Abstract
OBJECTIVE To investigate whether the activation of NOD like receptor protein 3 (NLRP3) signaling pathway in vascular endothelial cells induced by heat stress (HS) could be inhibited by ethyl pyruvate (EP). METHODS Human umbilical vein endothelial cells (HUVEC) were cultured in vitro, and the cells in logarithmic growth phase were taken to carry out experiment. Different temperatures gradients (39, 41, 43 centigrade for 4-hour HS) and different duration gradients (43 centigrade continuously HS respectively for 2, 3, 4 hours) were set up respectively. For HS group, HUVECs were placed in incubators with corresponding different conditions to carry out HS, then 43 centigrade persisting for 4-hour HS (43 centigrade, 4 hours) was selected as the final experimental condition; during HS, EP 10 mmol/L was added. For control group, the cells were synchronously cultured in 37 centigrade cell incubator. The protein expression of NLRP3 in HUVEC and activity of aspartate specific cysteine protease 1 (caspase-1) were detected with Western blotting; enzyme linked immunosorbent assay (ELISA) was used to detect the released levels of interleukins (IL-18 and IL-1β) in the cell culture supernatant fluid after HS. RESULTS After HS, the protein expression level of NLRP3 in HUVEC was increased with the increasing of HS temperature or extension of exposure duration in HS condition, and reached to the highest in 43 centigrade for 4 hours. Compared with control group, there was significant difference [NLRP3 protein expression (NLRP3/GAPDH): 1.54±0.08 vs. 0.97±0.17, P < 0.05]; after EP intervention, the expression of NLRP3 and the activation of caspase-1 in HUVEC were significantly lower than those in HS group [NLRP3 protein expression (NLRP3/GAPDH): 1.15±0.07 vs. 1.57±0.09, caspase-1 activity: 40.87±6.54 vs. 59.75±9.92, both P < 0.05], moreover, the released levels of IL-18 and IL-1β in cell supernatant were also significantly decreasing than those in HS group [IL-18 (ng/L): 1.09±0.08 vs. 1.41±0.13, IL-1β (ng/L): 1.38±0.10 vs. 2.02±0.10, both P < 0.05]. CONCLUSIONS The activation of NLRP3 signaling pathway in vascular endothelial cells induced by HS could be significantly inhibited by EP, which helps to reduce the release of inflammatory cytokines from vascular endothelial cells induced by HS.

Abstract
Objective: To analyze clinical features, diagnosis, treatment and prognosis of pregnancy-related lymphocytic hypophysitis (LyH). Methods: The clinical data of 16 cases diagnosed as pregnancy-related LyH at Chinese PLA General Hospital between October 2010 and November 2019 were reviewed. Results: Sixteen patients were included (aged 20-40 years). All patients' symptoms occurred from the last 2 months of pregnancy to 12 months postpartum, with 6 cases in the third trimester and 10 cases during postpartum, and all the patients were diagnosed after delivery. Six patients had lymphocytic adenohypophysitis (LAH), 4 patients had lymphocytic infundibuloneurohypophysitis (LINH), 4 patients had lymphocytic panhypophysitis (LPH), and 2 had lymphocytic hypothalamitis. Eight patients presented with symptoms of intracranial space-occupying lesions, 14 patients had symptoms of anteriorpituitary hormone deficiencies, 9 patients had central diabetes insipidus (CDI), and 2 had hyperprolactinemia. Pituitary MRI showed that the pituitary presented with diffuse enlargement, pituitary stalk thickening, disappearing of high-intensity signals in posterior pituitary and space-occupying lesions in the infundibulum of hypothalamus. Nine patients were treated with immunosuppressive agent, 3 patients alleviated the space-occupying effects after surgery, and 4 patients recovered spontaneously. Fourteen patients were followed up with a period of 3-98 months. Four patients had a relapse, 2 patients had a complete remission, and 12 patients needed long-term hormone replacement therapy. Conclusions: Clinical manifestations of pregnancy-related LyH are diverse. LyH should be suspected in pregnant or postpartum women with a sellar mass to avoid missed diagnosis or misdiagnosis. Immunosuppressant therapy is effective. Overall, LyH patients have a favorable prognosis.

Abstract
OBJECTIVE This study investigated whether melatonin alleviates intervertebral disc degeneration (IVDD) by promoting autophagy through inhibiting the NF-κB signaling pathway. METHODS Magnetic resonance imaging (MRI), hematoxylin and eosin (H&E) staining and Safranin-O staining were used to measure disc degeneration in rat needle puncture IVDD models, and melatonin was injected intraperitoneally in the treated group to test its function. The expression of autophagy and extracellular matrix (ECM) degeneration related-markers were measured in the discs using immunohistochemistry. Transmission electron microscopy was used to evaluate the activation of autophagy in human nucleus pulposus (NP) tissues with different degenerated statuses. The expression of autophagy and disc degeneration related-markers were detected in NP cells by Western blot, RT-qPCR, and immunofluorescence analyses. NF-κB signaling pathway involvement was studied by lentivirus-mediated knockdown, Western blotting, and immunohistochemistry and immunofluorescence staining. RESULTS Melatonin prevented IVDD development in vivo and in vitro. Compared to non-degenerated disc tissues, degenerated human NP tissues showed a decrease in the autophagy-specific marker LC3B and the numbers of autophagosomes and autolysosomes, whereas the p62 level was increased; similar results were observed in rat IVDD models, indicating a negative correlation between autophagy and IVDD. Furthermore, both in vivo and in vitro studies found that melatonin application induced autophagy and reduced ECM disc degradation. Melatonin was also shown to regulate autophagy by inhibiting the NF-κB signaling pathway in vivo and vitro. CONCLUSION This study indicates that melatonin prevents IVDD by promoting autophagy, indicating its possible therapeutic potential for controlling the progression of IVDD.

Abstract
BACKGROUND Sepsis, a life-threatening systemic syndrome related to inflammatory response, usually accompanied by major organ dysfunctions. The aim of the present study was to elucidate the role by which Shengmai injection (SMI) acts to septic cardiomyopathy. METHODS Initially, the induced mice with septic cardiomyopathy were treated with SMI or normal saline (NS) with oe-caspase-3, and HL-1 cells were treated with oe-Beclin-1 and oe-caspase-3 and then cultured with lipopolysaccharide (LPS). Subsequently, we measured the cardiac troponin I (cTnI) level, and expression of mitochondrial autophagy protein (parkin and pink1) and myocardial cell autophagy-related proteins (LC3-II and LC3-I). Additionally, we identified the cleavage of Beclin-1 by caspase-3 and detected the changes of mitochondrial membrane potential, level of reactive oxygen species (ROS), and apoptosis of myocardial cells in myocardial tissues of mice. RESULTS It has been demonstrated that SMI contributed to the increase of myocardial mitochondrial autophagy, reduction of cTnI level, and elevation of mitochondrial membrane potential in septic cardiomyopathy mice. Both in vitro and in vivo experiments showed that caspase-3 promoted cleavage of Beclin-1 and release of ROS, whereas repressed lipopolysaccharide (LPS)-induced mitochondrial autophagy. Furthermore, the facilitation of myocardial mitochondrial autophagy and protection of myocardial mitochondria by SMI through inhibition of cleavage Beclin-1 by caspase-3 in septic cardiomyopathy mice were also proved by in vivo experiments. CONCLUSION Taken together, SMI could protect myocardial mitochondria by promoting myocardial mitochondrial autophagy in septic cardiomyopathy via inhibition of cleavage of Beclin-1 by caspase-3. Our study demonstrates that SMI could represent a novel target for treatment of septic cardiomyopathy.

Abstract
Objective: To compare the differences of brain functional damage of subtypes of patients with Cushing's syndrome (CS). Methods: A total of 11 adrenocorticotropic hormone (ACTH)-dependent CS patients and 29 ACTH-independent CS patients were recruited from Chinese PLA General Hospital between September 2015 and March 2017 with confirmed CS. The psychiatric scales and brain task functional magnetic resonance imaging (fMRI) were evaluated. Results: A total of 40 patients (34 females, 6 males) with a mean age of (39.20±12.10) years and a median education level of 12 (9, 16) years were enrolled. ACTH-dependent patients had significantly worse performance than the ACTH-independent patients in response to the depression evaluation (64.6±6.1 vs 56.2±12.8, P=0.008), positive emotion (17.8±4.2 vs 24.3±7.2, P=0.008) and CS life quality [31(29,33) vs 42(29,51), P=0.040]. In the reaction to positive target pictures, ACTH-dependent CS patients showed stronger activation in left superior temporal gyrus compared with patients in ACTH-independent group, while the activation degree of their bilateral dorsal anterior cingulate cortex, bilateralsuperior frontal gyrus and left middle frontal gyrus was much worse. In the reactions to negative target pictures, ACTH-dependent CS patients had weaker activation in bilateral cerebellum, left superior frontal gyrus, left middle frontal gyrus, left precuneus and right postcentral gyrus, compared with patients in the ACTH-independent CS group (P<0.01, AlphaSim corrected). The activation degree of some regions whose brain function was different between the two groups was correlated to the cortisol level, ACTH level, 24 h urinary free cortisol (UFC) level, depression evaluation and negative emotion assessment (all P<0.05). Conclusions: The severity of the depression and the life quality of patients in ACTH-dependent group are worse than ACTH-independent CS patients. The brain function of ACTH-dependent CS patients is much weaker.

Abstract
Abstract
Background Obesity is strongly associated with insulin resistance and elevated plasma glucose levels. The rs9356744 polymorphism in the CDKAL1 gene is associated with body mass index (BMI) only in East Asians. Here, we examined the effect of the rs9356744 polymorphism on glucose-related traits and prediabetes in Chinese adults.
Methods A total of 2 357 participants were enrolled from the Cardiometabolic Risk in Chinese (CRC) Study, including 499 persons with prediabetes, 204 persons with type 2 diabetes, and 1 654 normoglycemic controls. The rs9356744 polymorphism in CDKAL1 was genotyped and analyzed in all participants.
Results Despite the positive relationship between obesity and glucose traits, the T allele of rs9356744, which is associated with a predisposition to obesity, was correlated with lower levels of 2-h oral glucose tolerance test (OGTT) plasma glucose (2hPG) (β=− 0.2104 and P=0.0233), glycated hemoglobin (HbA1c) (β=− 0.0551 and P=0.0298) and higher levels of homeostasis model of assessment β-cell function (HOMA-B) (β=5.282 and P=0.0424). After further adjustment for BMI, the levels of HOMA-B maintained a similar increased trend across rs9356744 genotype (β=3.277 and P=0.1958). In stratified analyses, the associations of rs9356744 with 2hPG and HbA1c were significant for individuals with a low BMI. Moreover, an antagonism action of BMI and rs9356744 on 2hPG (P for interaction=0.0055) was observed. In addition, we found a protective effect of rs9356744 on prediabetes.
Conclusions The CDKAL1 rs9356744 T allele associated with a predisposition to obesity showed a protective effect on HbA1c, 2hPG, and prediabetes. BMI was mediator of the association between the genetic variant and HbA1c, 2hPG, and prediabetes.

Abstract
In two patients right atrial ball thrombi developed following prolonged subclavian cannulation for hemodialysis. One patient died, the other had the ball thrombus removed by open heart surgery. It appears that repeated friction of the catheter tip may have damaged the endothelium of the right atrial wall. This hitherto unrecognised complication might be prevented by ensuring that subclavian hemodialysis catheters are never allowed to reach as far as the right atrium.

Abstract
Objective: To analyze clinical features, prognosis and treatment of lymphocytic hypophysitis (LYH). Methods: The clinical data, treatments and outcomes of 18 cases diagnosed as LYH at Chinese PLA General Hospital between January 2001 and July 2017 was respectively reviewed. Results: Eighteen patients with histology-proven LYH (13 females and 5 males ) were identified. All lymphocytic adenohypophysitis (LAH) were females(n=6), two of whom were associated with pregnancy. Eleven patients (6 females and 5 males) had lymphocytic panhypophysitis (LPH) and one(female) had hypothalamitis. Pre-treatment evaluation revealed that 11 patients presented with symptoms of intracranial space-occupying lesions, 12 patients had symptoms of anterior pituitary hormone deficiencies, and 12 patients had central diabetes insipidus (CDI). All patients had space-occupying lesions on magnetic resonance imaging (MRI), which were symmetrically enlarged and homogenously enhanced with or without pituitary stalk thickening. Before or after surgery, 11 patients received immunosuppressant therapy or radiotherapy to alleviate space-occupying effect. After 4-204 months follow-up, 5 patients had a relapse and received immunosuppressants, radiotherapy or surgery to achieve remission. Full recovery (both symptomatic and radiographic) was seen in 6 patients, and 11 patients maintained stable replacement therapy. Conclusions: LYH presents with acute space-occupying effects such as headache, visual disturbances, hypopituitarism, CDI and mild hyperprolactinemia, especially with characteristic radiographic manifestations. Usually, surgery reliably establishes diagnosis, and immunosuppressant therapy is a necessity. On the whole, LYH has a good prognosis.

Abstract
Background Transcatheter aortic valve replacement (TAVR) is widely applied for the treatment of severe aortic stenosis (AS) in developed countries; however, in China, it is still in the early stage of utilization. On the basis of previous studies, this work explored the feasibility of TAVR in patients with severe AS in China and analyzed the cause of death in four cases. Methods This retrospective study included 20 patients who had severe AS and underwent TAVR with a balloon-expandable system (Edwards SAPIEN XT) in our hospital from January 2011 to June 2016. The valve and heart functions of 16 survivors before and after the TAVR procedure were compared. TAVR endpoints, device success, and adverse events were assessed according to the definitions of the Valve Academic Research Consortium-2 (VARC-2). Results There were 13 male and seven female patients aged 65–81 years (average, 73.15) who underwent TAVR. The TAVR approach was transfemoral in 19 patients and transapical in one patient. Four patients died (two of coronary artery occlusion and two of aortic annulus rupture) during the TAVR procedure or shortly after; six patients had mild paravalvular leakage, and the rest of the patients showed a significant improvement in cardiac function. During the follow-up period (2–62 months), one patient died of lung cancer 13 months after the TAVR procedure. Conclusion TAVR with a balloon-expandable system is safe and effective and can be used for patients with severe AS in China. It requires careful patient selection and preoperative assessment so as to reduce the 30-day postoperative mortality rate.

Abstract
Diaphragm dysfunction is common in clinical work, which is a frequently important cause of ventilation weaning failure ignored by clinicians. Assessing diaphragmatic function while weaning helps early detection and prevention of weaning failure, so as to improve the clinical outcome of patients on mechanical ventilation (MV). Reviewing studies of diaphragmatic function evaluation in weaning, we can find that assessing diaphragmatic function during weaning can help guide weaning. Weaning predictors including pressure index, electrophysiological index and morphological index, among which bedside ultrasound as a morphological index is widely used in intensive care unit (ICU), which is simple, non-invasive, and easy to operate. It is also accurate in the assessment of diaphragmatic function and guidance on weaning, which is worthy of promotion and application.

Abstract
Objective: To summarize and analyze the clinical features and etiologies in hospitalized patients with syndrome of inappropriate antidiuretics (SIAD) during the past 25 years. Methods: All data of 128 patients with SIAD admitted to Chinese PLA General Hospital since January 1991 to January 2016 were collected. SIAD was diagnosed based on the 1957 criterion. Results: (1) The most frequent causes of increased inappropriate secretion of vasopressin were malignant tumors, lung diseases (e. g. pneumonia), and central nervous system diseases, in which malignant tumors accounted for 38.28% of the SIAD. (2) During the past 25 years, the proportion of malignant diseases declined from 4/7 to 35.29%, while, the proportion of pulmonary infection increased from 1/7 to 35.29% (P<0.05). (3) The patients with malignant tumors had the lowest serum sodium and serum osmolality among all SIAD patients. (4) CT scan had a high diagnostic value for chest and brain detection. (5) Among three SIAD subjects with unknown reasons at onset, two were diagnosed with small cell lung cancer and one with gastric cancer during follow-up. Conclusion: The etiology of SIAD is complex and it could be attributed to multifarious etiological factors. Malignant tumors account for the largest proportion of all patients, and pulmonary infection was ranked in second place. Cautions on tumors have to be taken when serum sodium of a SIAD patient is below 118.1 mmol/L.

Abstract
UNLABELLED In a random sample of postmenopausal Chinese women, the prevalence of radiographic vertebral fractures increased from 13% between ages 50 and 59 to over 50% after age 80 years. A model with seven clinical risk factors predicted the probability of vertebral fractures as well with as without BMD and better than a model with only three risk factors. More than half an hour of outdoor activity per day might correlate with lower risk of vertebral fracture in this population. INTRODUCTION We aimed to describe the prevalence and develop a model for prediction of radiographic vertebral fractures in a large random sample of postmenopausal Chinese women. METHODS We enrolled 1760 women from an age-stratified random sample of postmenopausal women in Beijing, China. The presence of vertebral fracture was assessed by semi-quantitative grading of lateral thoracolumbar radiographs, risk factors by interview, bone mineral density (BMD) of the proximal femur and lumbar spine by dual x-ray absorptiometry (DXA), and markers of bone turnover from a fasting blood sample. Associations of these factors were analyzed in logistic models and discrimination by areas of receiver operating characteristics curves (AUC). RESULTS The prevalence of vertebral fracture, ranged from 13.4% ages 50 to 59 years old to 58.1% at age 80 years or older. Older age, a history of non-vertebral fracture, lower femoral neck BMD T-score, body mass index (BMI), height loss, housework, and less than half an hour of outdoor activity were significantly associated with increased probability of having a vertebral fracture. A model with those seven factors had a similar AUC with or without BMD and performed better than a simple model with three factors. CONCLUSION This study is from a true random sample of postmenopausal women in urban China with high response rate. The prevalence of vertebral fractures in postmenopausal women in Beijing increases from 13% under age 60 to over 50% by age 80 years. A model with seven clinical risk factors with or without BMD is better than simple models and may guide the use of spine x-rays to identify women with vertebral fractures. More than half an hour of outdoor activity might correlate with lower risk of vertebral fracture in this population.

Abstract
Purpose: To establish a novel release kinetics evaluation method of Chinese compound medicine (Sedum Sarmentosum compound) with xCELLigence Real-Time Cell-based Assay (RTCA) system. Methods: Cell lines sensitive to Sedum Sarmentosum compound are screened, and cell index-time (CI-T) graphs and cell index release kinetics models are established based on the cell index (CI) monitored. The methodological studies of precision and repeatability were processed by the cell monitors system. The release profiles of the sustained-release Sedum Sarmentosum compound were determined. Consequently, the sustained-release property was characterized by the kinetic parameters based on the cell-index. Results: The accumulative release rate based on cell index of Sedum sarmentosum compound sustained-release preparation was determined and it had a good correlation with time, fitting better with First-order model, Higuchi model and Ritger-Peppas model, and fitting best with Weibull model. It indicated that the release rate is proportional with the diffusion coefficient. Conclusion: The new method of cell-index release kinetics may provide a quantitative description for the release of the multi active agents from Traditional Chinese Medicines. The application of xCELLigence RTCA system for evaluating the release kinetics of Chinese compound medicine is feasible.

Abstract
BACKGROUND Apoptosis has been demonstrated to be an important upstream event in the pathogenesis of chronic obstructive pulmonary disease (COPD). Cyclooxygenase-2 (COX-2) seems to be biologically relevant in COPD. However, the role of COX-2 in the apoptosis in vascular endothelial cells induced by cigarette smoke extract (CSE) remains to be elucidated. Our recent study found that the prostacyclin, one of the COX products in the microvascular endothelium, inhibited apoptosis in the emphysematous lungs of rats induced by CSE. In order to clarify the role of COX-2 in the apoptosis of vascular endothelial cells induced by CSE, we performed the present experiment to elucidate it. METHODS Twenty surgical lung specimens were obtained from 6 patients with COPD, 7 smoking controls and seven nonsmoking controls. The apoptotic index (AI) and COX-2 protein expression were detected in lung tissues. To further investigate the effects of CSE on the apoptosis and COX-2 expression in a human vascular endothelial cell line, the apoptosis rate and COX-2 expression were examined in human umbilical vein endothelial cells (ECV304) under exposure to varied concentrations of CSE as well as under exposure to 5.0% CSE for varied durations. Repeatedly, the apoptosis rate and COX-2 expression in ECV304 cells under 5.0% CSE were examined after exposing to varied concentrations of celecoxib, a highly selective COX-2 inhibitor. RESULTS Significantly increased AI and expression of COX-2 were found both in the lungs of patients with COPD and smoking controls compared with nonsmoking controls. The CSE induced apoptosis in ECV304 cells in means of both dose-dependent and time-dependent manners. The COX-2 was slightly expressed in the cells after exposing to 5% CSE for 3 and 6 h, and markedly expressed after the exposure time for 9 and 12 h, but vanished after 24 h of the exposure. Of interest, with the completely block of the COX-2 expression by celecoxib at 50.0 µmol/L, the apoptosis rate was markedly increased again in ECV304 cells under exposure to 5.0% CSE. CONCLUSIONS Endothelial cell apoptosis and the expression of COX-2 protein were increased in both COPD patients and CSE-induced vascular endothelial cells. Of interest, it seems that the COX-2 probably had a protective role against the apoptosis in the vascular endothelial cells induced by cigarette smoking.

Abstract
Cryptorchidism is one of the most common congenital anomalies and affects 2-4% of full-term new born boys. Its aetiology is poorly understood at present. HOXA10 plays a pivotal role in regulation of testicular descent. Male mice mutant for Hoxa10 exhibit unilateral or bilateral cryptorchidism as a result of impaired development of the gubernaculums. In this study, we performed mutation analysis of HOXA10 gene in a cohort of 98 cryptorchid patients. And we found a mutation (N27K) in a boy with unilateral cryptorchidism. The mutation was not detected in 106 healthy controls. Both in silico analyses and functional studies showed that the mutation affected the function of HOXA10. The results demonstrated that mutation in HOXA10 gene contributes to the pathogenesis of cryptorchidism, but may not be a common cause.

Abstract
The c-Jun NH2-terminal protein kinase (JNK) pathway has been implicated in mammary tumor development. However, the molecular mechanisms regulating JNK activity in breast cancer cells remain unclear. Here, we report that the inhibition of ubiquitination-like post-translational modification neddylation through different strategies results in enhanced basal JNK phosphorylation in human breast cancer cells. The upregulation of basal JNK phosphorylation upon neddylation inhibition is independent of the deneddylation of Cullins, the well-characterized neddylation substrates. Since augmented basal JNK phosphorylation via ectopic MKK7 expression impedes proliferation and the epithelial-to-mesenchymal transition (EMT) phenotype, the neddylation system might contribute to mammary tumor development partially through limiting basal JNK phosphorylation. Further exploration reveals that MKK7, a JNK-specific MAP2K, undergoes neddylation in human breast cancer cells. MKK7 co-precipitates with a fragment of Ran-binding protein 2 (RanBP2), a large multimodular and pleiotropic protein that has been recognized as a SUMO E3 ligase. Knockdown of RanBP2 attenuates MKK7 neddylation and augments basal JNK phosphorylation without affecting the neddylation of Cullins, whereas ectopic expression of a RanBP2 fragment possessing SUMO E3 activity (RanBP2ΔFG) manifests the opposite effects. In vitro neddylation assays confirm that RanBP2ΔFG works as the neddylation E3 ligase for MKK7. The basal kinase activity of endogenous MKK7 increases upon RanBP2 knockdown but decreases upon the ectopic expression of RanBP2ΔFG. Furthermore, purified MKK7 shows reduced basal kinase activity after in vitro neddylation by RanBP2ΔFG. Consistently, RanBP2 knockdown leads to reduced proliferation and impaired EMT phenotype in human breast cancer cells and the effects of RanBP2 knockdown are reversed by simultaneous MKK7 knockdown. Taken together, our data suggest that MKK7 undergoes neddylation in human breast cancer cells, which limits its basal kinase activity.

Abstract
In this paper, we propose a simultaneous design method of motion and external force trajectories for knee joint rehabilitation based on the biomechanical analysis of the lower limb. In this method we assume to use two robots manipulators which provide forces and moments at shank and thigh. We developed a 7 degree of freedom musculoskeletal model of lower limb with 19 muscles. The valuation function of rehabilitation efficiency e has been maximized by Genetic Algorithm (GA) that refers to the musculoskeletal model and tunes motion trajectory of the robots and forces acting on the shank and thigh.

Abstract
PURPOSE This study aimed to investigate the synergistic anti-tumor effects of tumstatin 185-191 and cisplatin in non-small cell lung carcinoma cells (NSCLC) (A549 cells and cisplatin resistant A549/DDP cells), and the potential role of Akt signaling pathway was also explored. METHODS A549 or A549/DDP cells were treated with Tum185-191 or Tum185-191 plus cisplatin. Cell viability was assessed by modified MTT assay. 50% inhibiting concentration (IC50) and reversing drug-resistance index (RI) of chemotherapeutics were determined by MTT assay. Cell apoptosis was measured by Hoechst 33258 staining and flow cytometry. The activation of Akt signaling pathway was evaluated by immunocytochemistry and Western blot assay. RESULTS Tum185-191 inhibited the proliferation of A549 cells and A549/DDP cells. In the presence of Tum185-191 (20 and 40 μM), IC50 of cisplatin reduced significantly in A549 cells and A549/DDP cells. Combined use of tumstatin 185-191 and cisplatin exerted synergistic effects in promoting apoptosis. A549 and A549/DDP cells had a high expression of p-Akt, and Tum185-191, but not cisplatin, significantly inhibited p-Akt expression. Combined use of cisplatin and Tum185-191 failed to further inhibit p-Akt expression. After Tum185-191 treatment, the increased p-Akt expression was observed at 15 min, peaked at 30-60 min, but disappeared at 120 min. CONCLUSION Tum185-191 increases the apoptosis, inhibit the proliferation, enhance the sensitivity of A549 cells to cisplatin and also partly reverse the resistance of A549-DDP cells to cisplatin, which is at least partially mediated by inactivating Akt pathway. These findings provide evidence for the chemotherapy of NSCLC with Tum185-191 and cisplatin.

Abstract
OBJECTIVE The causal relationship between serum uric acid (SUA) level and non-alcoholic fatty liver disease (NAFLD) has not yet been clarified. The objective of the study was to determine the association between SUA and NAFLD, as well as assess the interactions between SUA and other metabolic risk factors regarding NAFLD. PATIENTS AND METHODS The study samples related to a community-based health examination survey conducted in Central China. Initially, a total of 24,878 patients with medical examination were included. After excluding the individuals with confounding factors, the remaining 21,798 subjects with biomarkers available were included in the present study. RESULTS The data show that the risk of NAFLD significantly increased with the elevated SUA levels. Further adjustments for sex, age, and other confounding metabolic factors did not change the increasing trend of NAFLD risk. The odds ratios [ORs, 95% confidence interval (CI)] of NAFLD across the increasing quintiles of SUA were 1.00, 1,530 (1.174-1.995), 2.24 (1.714-2.886), 2.636 (2.019-3.441), and 3.714 (2.828-4.877) (p for trend < 0.0001). Also, significant interaction was found between SUA and prehypertension in relation to the NAFLD risk (p for interaction < 0.05). CONCLUSIONS SUA was significantly associated with NAFLD risk, independent of other metabolic risk factors, and SUA also had significant interaction with prehypertension regarding the risk of NAFLD.
