Abstract
Objective: To investigate the clinical effects of different types of tissue flaps in repairing the wounds with steel plate exposure and infection after proximal tibial fracture surgery. Methods: A retrospective observational study was conducted. From January 2015 to December 2021, 11 patients with steel plate exposure and infected wounds after proximal tibial fracture surgery who met the inclusion criteria were admitted to Jiangxi Provincial General Hospital of Armed Police, including 9 males and 2 females, aged 26 to 61 years. The wounds were located on the lateral side of the proximal leg in 5 cases, on the medial side of the proximal leg in 2 cases, and on the medial side of the proximal leg and the anterior tibia below the knee in 4 cases. After debridement, the wound area was 14 cm×6 cm-22 cm×11 cm. The wounds were repaired with different types of tissue flaps, and the steel plates were removed immediately if necessary, according to the infection around the steel plates. The reverse anterolateral thigh myocutaneous flap pedicled with the muscle containing the terminal small branch of the descending branch of the lateral circumflex femoral artery was used in 3 cases; the medial gastrocnemius muscle flap combined with the medial half of soleus muscle flap was used in 6 cases, and the lateral gastrocnemius muscle flap combined with the anterior tibial muscle flap was used in 2 cases. After the muscle flaps had stable blood supply, the wounds were closed with thin intermediate thickness skin graft from the healthy thigh. The area of myocutaneous flap ranged from 15 cm×7 cm to 18 cm×8 cm, and the area of muscle flap ranged from 6.0 cm×4.0 cm to 18.0 cm×12.0 cm. Among the 3 patients who were treated with reverse anterolateral thigh myocutaneous flap, the wounds of flap donor site on thighs were closed by direct suturing in 2 cases, and the wound in the flap donor site of thigh in 1 case that was not closed after suture was repaired with thin intermediate thickness skin graft from healthy thigh. The incisions in the flap donor sites of 8 cases treated with calf muscle flaps were sutured directly. After surgery, the survivals of tissue flap and skin graft on the muscle flap, wound healing status and wound healing time in recipient sites of tissue flaps, suture site healing in flap donor site, and survival of skin graft were observed and recorded. Whether the steel plate was removed after operation and during follow-up was recorded. During follow-up, the shape and texture of tissue flap, whether the recipient site of tissue flap had redness, swelling, ulceration, or sinus formation were observed, the fracture healing time was recorded. At the last follow-up, the knee joint flexion and extension range of motion was measured and the knee joint function was evaluated according to Hohl's knee joint function evaluation criteria; the plantar flexor muscle strength of ankle joint was measured in 8 patients who were treated with calf muscle flaps for wound repair; the Vancouver scar scale (VSS) was used to evaluate the scar condition in the flap donor site, and whether the scar affected the movement of the affected limbs was observed. Results: Tissue flaps of 11 patients all survived after surgery. The distal end of the reverse anterolateral thigh myocutaneous flaps was necrotic in 1 patient, and the wound was healed after dressing change and grafting with thin intermediate thickness skin from healthy thigh. The distal muscle necrosis of the medial gastrocnemius muscle flap was observed in 2 patients, and the granulation tissue grew well after dressing change. The skin graft on the muscle flap survived well. All the wounds in the recipient sites of tissue flaps were healed, and the healing time was 13 to 42 days after tissue flap transplantation. The suture site of flap donor site healed, and the skin graft survived well. In 1 patient, the steel plate was removed when the wound was repaired with the medial gastrocnemius muscle flap combined with the medial half of soleus muscle flap. One patient still had exudation after 3 weeks of wound repair with the reverse anterolateral thigh myocutaneous flap pedicled with the muscle containing the terminal small branch of the descending branch of the lateral circumflex femoral artery, and the wound was healed after removing the steel plate. The steel plates of the other patients were preserved. During the follow-up of 6-25 months, except for 1 reverse anterolateral thigh myocutaneous flap had bloated pedicle, the other tissue flaps had good appearance and texture. One patient had redness and swelling in the recipient site of the tissue flap at 6 weeks after discharge, and the redness and swelling subsided without recurrence after anti-infection treatment. In 1 patient, repeated rupture and exudation occurred in the recipient site of tissue flap in 3 months after discharge, resulting in sinus tract formation, which was healed after the removing of steel plate. The fracture healing time of patients ranged from 6 to 15 months after injury. At the last follow-up, the knee joint function was evaluated as excellent in 4 cases, good in 6 cases, and poor in 1 case. Among the 8 patients who were treated with calf muscle flaps for wound repair, 7 patients had ankle joint plantar flexor muscle strength of grade Ⅵ, and 1 patient had ankle plantar flexor muscle strength of grade Ⅴ. The VSS scores of scars in the flap donor sites ranged from 2 to 7, and scars did not significantly affect the movement of the affected limbs. Conclusions: The reverse anterolateral thigh myocutaneous flap pedicled with the muscle containing the terminal small branch of the descending branch of the lateral circumflex femoral artery and the gastrocnemius muscle flap combined with soleus muscle flap or anterior tibial muscle flap are the derived types of the commonly used reverse anterolateral thigh myocutaneous flap and gastrocnemius muscle flap. Using them to repair the wounds with steel plate exposure and infection after proximal tibial fracture surgery can not only ensure the smooth operation, but also preserve the steel plate and promote fracture healing as much as possible, without significantly affecting the function of the affected limb.

Abstract
Objective: To explore the correlation between the morphological characteristics of retinal microvessels and diabetic kidney disease (DKD) in patients with type 2 diabetes mellitus (T2DM). Methods: The clinical data and fundus photography of patients with T2DM treated in the First Affiliated Hospital of Zhengzhou University from January 2018 to December 2020 were retrospectively collected and analyzed. According to the presence of abnormal renal function, the patients were divided into DKD group and control group. The morphology and structure of fundus vessels were digitized by U-Net depth convolution neural network, and the correlation between fundus vascular morphology and DKD was analyzed by multivariate logistic regression. Results: A total of 648 patients with T2DM were enrolled, including 410 males and 238 females, and aged (53±10) years. There were 398 and 250 cases in control and DKD groups, respectively. Meanwhile, 1 296 fundus images were collected. Compared with control group, the male ratio (68.4% vs 60.1%, P=0.032), age [(54±9) vs (52±10) years, P=0.005], blood pressure [(136.8±17.3) vs (130.3±15.4) mmHg(1 mmHg=0.133 kPa), P<0.001], total cholesterol [(4.5±1.4) vs (4.2±1.0) mmol/L, P=0.009], triglyceride [M (Q1, Q3)][1.7 (1.2, 3.0) vs 1.4 (1.0, 2.3) mmol/L, P<0.001] and Cystatin C [(0.9 (0.8, 1.0) vs 0.8 (0.7, 0.9) mg/L, P<0.001] were higher in the DKD group, while high-density lipoprotein [(1.0±0.3) vs (1.1±0.3) mmol/L, P=0.001] was lower in the DKD group. Multivariate logistic regression analysis showed that the risk of DKD in the third quartile (right eye: OR=1.825, 95%CI: 1.204-2.768, P=0.005) and fourth quartile (left eye: OR=1.929, 95%CI: 1.218-3.055, P=0.005) was higher than that in the lowest quartile of vascular curvature after adjusting for age and gender. The increase of average diameter of retinal vein was associated with the risk of DKD (left eye: OR=1.044, 95%CI: 1.013-1.075, P=0.005). The decrease of vascular fractal dimension (fourth quartile of left eye: OR=0.444, 95%CI: 0.199-0.987, P=0.046) and retinal vascular density (the second and fourth quartile of the right eye: OR=0.639, 95%CI: 0.409-0.998, P=0.049; OR=0.534, 95%CI: 0.331-0.864, P=0.010) were related to the risk of DKD. Conclusions: The abnormal morphological characteristics of retinal microvessels are related to the occurrence of DKD. The increase of retinal vein diameter and the decrease of retinal vessel density correlate with the occurrence of DKD.

Abstract
Mortality due to severe burns has always been at a high level. A large number of studies have shown that the rapid onset of infectious symptoms and rapid progression of severely burned patients are closely related to the occurrence of cytokine storm. However, in clinical practice, cytokine storm monitoring, early warning, and symptomatic treatment are still in exploratory stage. This article reviews the cytokine storm and its related cytokines, the mechanism, early warning, and treatment of cytokine storm induced by burn infection, aiming to provide clinical references for reducing infection and mortality in severely burned patients.

Abstract
OBJECTIVE To quantitatively evaluate the trueness of five chairside three-dimensional facial scanning techniques, and to provide reference for the application of oral clinical diagnosis and treatment. METHODS The three-dimensional facial data of the subjects were collected by the traditional professional three-dimensional facial scanner Face Scan, which was used as the reference data of this study. Four kinds of portable three-dimensional facial scanners (including Space Spider, LEO, EVA and DS-FScan) and iPhone Ⅹ mobile phone (Bellus3D facial scanning APP) were used to collect three-dimensional facial data from the subjects. In Geomagic Studio 2013 software, through data registration, deviation analysis and other functions, the overall three-dimensional deviation and facial partition three-dimensional deviation of the above five chairside three-dimensional facial scanning technologies were calculated, and their trueness performance evaluated. Scanning time was recorded during the scanning process, and the subject's comfort was scored by visual analogue scale(VAS). The scanning efficiency and patient acceptance of the five three-dimensional facial scanning techniques were evaluated. RESULTS DS-FScan had the smallest mean overall and mean partition three-dimensional deviation between the test data and the reference data, which were 0.334 mm and 0.329 mm, respectively. The iPhone Ⅹ mobile phone had the largest mean overall and mean partition three-dimensional deviation between the test data and the reference data, which were 0.483 mm and 0.497 mm, respectively. The detailed features of the three-dimensional facial data obtained by Space Spider were the best. The iPhone Ⅹ mobile phone had the highest scanning efficiency and the highest acceptance by the subject. The average scanning time of the iPhone Ⅹ mobile phone was 14 s, and the VAS score of the subjects' scanning comfort was 9 points. CONCLUSION Among the five chairside three-dimensional face scanning technologies, the trueness of the scan data of the four portable devices had no significant difference, and they were all better than the iPhone Ⅹ mobile phone scan. The subject with the iPhone Ⅹ scanning technology had the best expe-rience.

Abstract
Objective: To explore the correlation between polycyclic aromatic hydrocarbons (PAHs) component phenanthrene and clinical indicators in patients on continuous ambulatory peritoneal dialysis (CAPD). Methods: A total of 22 patients who underwent peritoneal dialysis catheterization and regular dialysis in the First Affiliated Hospital of Zhengzhou University from June to August 2018 were selected. Meanwhile, 18 healthy adults who underwent physical examination were also selected as the control group. Fasting blood samples were taken to detect the concentration of PAHs components for comparison, and the correlation between PAHs components and clinical indicators was further analyzed. Results: There were 22 cases in CAPD group (13 males and 9 females), and aged (45±13) years, while there were 18 cases in control group (6 males and 12 females), and aged (41±13) years. The concentration of blood phenanthrene (PHE) was the highest in CAPD group [0.449 (0.254, 0.581) mg/L], and it was only lower than acenaphthene in the control group [0.081 (0.050, 0.444) mg/L], with a statistically significant difference between the two groups (P=0.008). The analysis of PHE and clinical indicators showed that the concentration of PHE in CAPD patients was negatively correlated with weekly urea clearance index (Kt/V), weekly creatinine clearance (Ccr) and leukocyte level, but positively correlated with triglyceride level (r=-0.743, -0.749, -0.655 and 0.610, respectively, all P<0.05). Simple linear regression analysis demonstrated that for every 0.1 mg/L increase in PHE concentration, weekly Kt/V, weekly Ccr and white blood cell count decreased by 0.226, 3.050 L/1.73 m2 and 0.512×109/L, respectively, but triglyceride level increased by 0.152 mmol/L (all P<0.05). Multiple linear regression analysis revealed that the blood PHE concentration of CAPD patients was negatively correlated with weekly Kt/V and Ccr levels (t=-2.402 and -2.368, respectively, both P<0.05). All CAPD patients were followed up for 3 years, during which 8 patients (36.4%) withdrew from peritoneal dialysis due to technical failure, and the baseline PHE concentration was higher than that of patients who did not quit peritoneal dialysis [0.572 (0.416, 0.662) vs 0.268 (0.120, 0.475) mg/L, P=0.003]. Eight patients (36.4%) had cardiovascular events, and the baseline blood PHE concentration was higher than that of patients without cardiovascular events [0.542 (0.389, 0.741) vs 0.373 (0.157, 0.545) mg/L, P=0.045]. Conclusion: PHE correlates with clinical indicators of CAPD patients, including Kt/v, Ccr, leukocyte and triglyceride.

Abstract
Diabetic wounds are a common complication of diabetic patients, and the incidence has been increasing in recent years. In addition, its poor clinical prognosis seriously affects the quality of life of patients, which has become the focus and difficulty of diabetes treatment. As the RNA regulating gene expression, non-coding RNA can regulate the pathophysiological process of diseases, and play an important role in the healing process of diabetic wounds. In this paper, we reviewed the regulatory role, diagnostic value, and therapeutic potential of three common non-coding RNA in diabetic wounds, in order to provide a new solution for the diagnosis and treatment of diabetic wounds at the genetic and molecular level.

Abstract
Objective: To investigate the prevalence and risk factors of chronic kidney disease (CKD) in diabetic patients aged over 40 years in Henan province. Methods: A cross-sectional study was conducted. Diabetic patients aged over 40 years were recruited from four cities including Xuchang, Zhumadian, Luoyang and Zhengzhou in Henan Province between June 2015 and July 2019. Multivariate logistic regression analysis was employed to analyze the risk factors for CKD. Results: A total of 3 067 diabetic patients were included in this study, including 1 238 males and 1 829 females. The mean age of all participants was (60.9±9.7) years and 85.8% (2 633/3 067) of them were living in rural areas. There were 1 155 participants who had CKD, and the overall prevalence of CKD was 37.7% (95%CI: 35.9%-39.4%). Compared with those without CKD, participants with CKD had older age [(61.4±10.3) vs (60.6±9.3) years], higher proportion of male patients (43.2% vs 38.7%), urban residents (19.4% vs 11.0%) and habitual drinkers (15.8% vs 12.7%), higher body mass index [(25.8±3.7) vs (25.4±3.6) kg/m2), higher proportion of having hypertension (57.0% vs 37.2%), hyperuricemia (10.7% vs 7.1%) and dyslipidemia (46.5% vs 42.7%) (all P<0.05). The prevalence of estimated glomerular filtration rate (eGFR) less than 60 ml·min-1·(1.73 m2)-1 and albuminuria was 4.9% (149/3 067) and 35.6% (1 092/3 067), respectively. Compared with rural participants [35.4% (95%CI: 34.4%-36.4%)], urban participants [51.6% (95%CI: 50.0%-53.2%)] had higher prevalence of CKD (P<0.001). Multivariate logistic regression analysis showed that habitual drinker (OR=1.27, 95%CI: 1.00-1.61, P=0.046), moderate physical activities (OR=1.23, 95%CI: 1.01-1.51, P=0.039), having hypertension (OR=2.27, 95%CI: 1.95-2.64, P<0.001), dyslipidemia (OR=1.21, 95%CI: 1.04-1.40, P=0.012) and hyperuricemia (OR=1.56, 95%CI: 1.21-2.02, P=0.001) were independent risk factors for CKD. Conclusions: The prevalence of CKD is high in diabetic patients who aged over 40 years in Henan province. The associated factors for developing CKD include habitual drinking, heavier physical activities and having chronic diseases. Targeted prevention and intervention for associated factors would be beneficial for controlling CKD in middle and old aged diabetic patients.

Abstract
Objective: To explore the relationship between left ventricular artery coupling and left ventricular work in patients with septic shock, and further clarified their predictive value for the prognosis of septic shock. Methods: In total, 56 patients with septic shock admitted in the Department of Critical Care Medicine of Peking Union Medical College Hospital were retrospectively enrolled between January 2016 and July 2021. The hemodynamic indexes and clinical data monitored by pulse indicator continuous cardiac output (PICCO) at different time points were collected. To reveal alterations of arterial elastance index (EaI), end-systolic elastance index (EesI), EaI/EesI, stroke work (SW), total cardiac function (PVA), and left ventricular ejection efficiency (LVEf) in patients with septic shock at different time points. The patients were divided into the death group (n=20) and survival group (n=36) according to the outcome of the ICU. The relationship between left ventricular work and left ventricular arterial coupling and its prognostic value were statistically analyzed. Results: A total of 56 patients were enrolled, 32 males and 24 females, aged (61±15) years. There was a significantly difference in EaI/EesI and LVEf between survivors and non-survivors with septic shock at 6 h (P<0.05). Further analysis showed that the correlation between EaI/EesI and LVEf was most evident at 6 h after intervention. EaI/EesI was negatively correlated with SW (rs=-0.500, P<0.001), and highly negative with LVEf (rs=-0.959, P<0.001). Both univariate logistic regression and multivariate regression analysis showed that EaI/EesI (adjusted OR=42.783, 95%CI: 2.725-671.819, P=0.008) and LVEf (adjusted OR=2.293, 95%CI:1.222-4.301, P=0.010) were risk factors for ICU prognosis of patients with septic shock. The receiver operating characteristic (ROC) curve analysis showed that EaI/EesI [area under the curve (AUC)=0.742±0.083, P=0.004; cut-off value 6.10, sensitivity 88.9%, specificity 65.0%] and LVEf (AUC=0.733±0.084, P=0.006; cut-off value 0.24, sensitivity 88.8%, specificity 60.0%) were both effective indicators for predicting the prognosis of patients with septic shock in the ICU. Moreover, EaI/EesI had a better prognosis value than LVEf (ΔAUC=0.120, Z=6.528, P=0.036). Conclusion: It's indicated that EaI/EesI was significantly correlated with SW and LVEf after 6 h of septic shock intervention; EaI/EesI and LVEf are risk factors and effective predictors of ICU prognosis in patients with septic shock. The predictive efficacy of EaI/EesI is greater than LVEF.

Abstract
N6-methyladenosine (m6A) exists widely in eukaryotes as a post-transcriptional modification. This modification is dynamically and reversibly regulated by methyltransferases and demethylases, and is involved in regulating biological effects through m6A binding proteins. Recent studies have elucidated that m6A is involved in embryonic skin morphogenesis, wound repair, and pathophysiological processes such as inflammatory response, angiogenesis, and fibrosis. This review summarizes the role of m6A and its related proteins in the related pathophysiological processes of wound repair, so as to provide a new theoretical basis for the treatment strategy of wound repair.

Abstract
Critical ultrasonography is widely used in ICU and has become an indispensable tool for clinicians. However, besides operator-dependency of critical ultrasonography, lack of standardized training mainly result in the physicians' heterogenous ultrasonic skill. Therefore, standardized training as well as strict quality control plays the key role in the development of critical ultrasonography. We present this quality control standards to promote better development of critical ultrasonography.

Abstract
Objective: To explore the risk factors and prognosis of sepsis-related cardiomyopathy. Methods: Patients with sepsis and septic shock admitted to the Critical Care Medicine Department at Peking Union Medical College Hospital from October 2017 to February 2021 were enrolled. Echocardiographic parameters including left ventricular ejection fraction (LVEF), tricuspid annular plane systolic excursion (TAPSE) and cardiac index (CI) were obtained within 24 h after admission. Hemodynamic parameters including heart rate, mean arterial pressure and central venous pressure were also collected. The risk factors of 45-day mortality were analyzed using Cox regression analysis. Kaplan-Meier survival analysis was performed to compare 45-day mortality among patients with normal left ventricle (LV) systolic function group, sepsis-related takotsubo cardiomyopathy (ST) and septic cardiomyopathy (SC) group as well as between patients with normal right ventricular (RV) function and patients with RV dysfunction. Results: According to LV systolic function, patients were categorized into three groups: normal group [174 (66.9%)], SC group [66 (25.4%)] and ST group [66 (25.4%)]. In comparison with those in normal group, patients in SC group and ST group had higher acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score and sequential organ failure assessment (SOFA) score (P<0.05). No difference was found between SC group and ST group regarding APACHE Ⅱ score and SOFA score(P>0.05). ST group had lower LVEF [33(28, 41)% vs. 45(38, 48)%, P<0.05], CI [2.29 (1.99, 2.53)L·min-1·m-2 vs. 3.04(2.61, 3.61) L·min-1·m-2, P<0.05] higher TAPSE [18.6(16.0, 21.2)mm vs. 15.1(12.5, 19.0)mm, P<0.05] than SC group. A Cox regression survival analysis showed that right ventricular dysfunction (RVD) was an independent predictor of 45-day mortality (HR=1.992, 95%CI 1.088-3.647, P=0.025). A Kaplan-Meier analysis revealed no significant difference regarding 45-day mortality among ST group [25.0%(5/20)], SC group [30.3%(20/66)] and normal group 18.4%(32/174)(P=0.158). RVD patients [38.0%(30/79)] had significantly higher 45-day mortality than patients with normal RV function [14.9%(27/181),P<0.001]. Conclusions: In comparison with SC patients, ST patients tend to have worse LV systolic function, lower cardiac output and better RV function. However, neither ST nor SC is associated with 45-day mortality. RVD is a risk predictor of 45-day mortality, which should be monitored in septic patients.

Abstract
Extracellular vesicles are nanoparticles secreted by most eukaryotic cells and play important roles in material transport and information transmission between cells, involved in inflammation, angiogenesis, antigen presentation, cell apoptosis, cell differentiation, and other biological processes. The culture supernatant of mesenchymal stem cells is rich in extracellular vesicles, and the extracellular vesicles can regulate the formation of new blood vessels, a key step in wound healing and tissue repair. The persistence of diabetic ulcers is closely related to the blocked formation of wound vascular network. This article reviews the role of extracellular vesicles derived from mesenchymal stem cells in promoting angiogenesis of diabetic ulcers, in order to provide a new idea for the treatment of diabetic ulcers.

Abstract
Objective: To explore the prevalence and related factors of hyperkalemia in patients with diabetic kidney disease (DKD). Methods: DKD patients from the Department of Nephrology of the First Affiliated Hospital of Zhengzhou University from January 2012 to December 2020 were selected, and the clinical data of the patients were retrospectively collected. The prevalence of hyperkalemia in DKD patients and the prevalence of hyperkalemia in patients with different age, gender and different stages of chronic kidney disease (CKD) were studied, and the related factors of hyperkalemia were further explored. Results: A total of 1 721 patients with DKD were included, with 1 117 males (64.9%) [mean age: (56±12) years] and 604 females (35.1%) [mean age: (59±12) years]. The blood potassium level of the study population was (4.93±0.77) mmol/L, in which the serum potassium level of male and female was (4.92±0.77) mmol/L and (4.93±0.76) mmol/L, respectively, and the difference was not statistically significant (P=0.752). Further grouping by CKD stage, the serum potassium levels of CKD stage 1-5 patients were (4.58±0.52), (4.65±0.47), (4.86±0.59), (5.21±0.79) and (5.61±0.88) mmol/L, respectively, and the difference was statistically significant (F=170.701, P<0.001). The prevalence of hyperkalemia was 37.0% (636/1 721). The prevalence of mild, moderate and severe hyperkalemia was 17.4%, 10.5% and 9.1%, respectively. There was no significant difference in the prevalence of hyperkalemia between men and women (36.8% vs 37.3%, χ²=0.035, P=0.851). The prevalence of hyperkalemia in CKD stage 1-5 patients was 16.3%, 21.2%, 37.6%, 55.2%, 72.5%, respectively, which increased with the severity of CKD (χ²=365.721, P<0.001). Multivariate logistic regression showed that estimated glomerular filtration rate (OR=0.975, 95%CI: 0.972-0.979), diastolic blood pressure (OR=0.985, 95%CI: 0.975-0.994) and serum sodium concentration (OR=0.972, 95%CI: 0.945-1.000) were the influencing factors of hyperkalemia in DKD patients. Conclusions: The prevalence of hyperkalemia in DKD patients was 37.0%. Glomerular filtration rate, diastolic blood pressure and serum sodium concentration were the influencing factors. The serum potassium level and the prevalence of hyperkalemia increased with the deterioration of renal function.

Objective: To explore the clinical characteristics and risk factors of pediatric patients with Wiskott-Aldrich syndrome (WAS). Methods: This was a case-control study. Clinical data of 165 cases of pediatric patients with WAS, who visited the Department of Rheumatology, Children's Hospital of Chongqing Medical University between January 2007 and August 2020 were retrospectively analyzed and divided into death group and survival group (control group) according to the prognosis in the follow-up. Two independent samples t-test, Welch approximate t-test, Mann-Whitney U test, Pearson χ² test, Yates corrected χ² test, or Fisher exact probability test were used for comparison between groups. Risk factors were analyzed by multivariate Logistic regression analysis. Results: A total of 165 patients with Wiskott-Aldrich syndrome were enrolled in this study, including 40 cases in the death group and 125 cases in the survival group. The WAS score was (4.1±0.8) score in the death group and (3.1±1.2) score in the survival group. The age was 19 (9, 28) months in the death group and 60 (36,86) in the survival group. The episode rates of recurrent infection and (or) severe infection, intracranial hemorrhage and eczema in the death group were significantly higher than those in the survival group (95.0% (38/40) vs.32.0% (40/125),25.0% (10/40) vs. 2.4% (3/125), 90.0% (36/40) vs. 72.0% (90/125), χ²=48.253, 18.325, 5.440, all P<0.05). Infection (22 cases, 55.0%) and intracerebral hemorrhage (15 cases, 37.5%) were the main causes of death, 3 cases (7.5%) died of severe graft-versus-host disease after transplantation. The Logistic regression model indicated that repeated infection and (or) severe infection and non-use of intravenous immunoglobulin (IVIG) replacement therapy were risk factors for death in Chinese WAS patients (OR values were 8.999 and 2.860, 95% CI were (2.041-39.667) and (1.375-5.950), respectively, all P<0.05). Conclusions: Recurrent and (or) severe infection is the main risk factor of death for WAS patietns. Regular IVIG treatment can improve the survival rate of patients with WAS.

Abstract
Objective: To investigate the clinicopathologic characteristics of hepatic echinococcus granulosus (HEG). Methods: Thirteen cases of HEG were collected from Linzhi People's Hospital between January 2017 to October 2020, and their clinicopathologic features, ultrasound classification, immunophenotype and histochemical data were analyzed, retrospectively and the relevant literature was reviewed. Results: Thirteen patients (5 male patients, 8 female patients) were included in this cohort, and the mean age was 40 years. The most common clinical presentation was mild abdominal distention and pain (9/13). Based on WHO-IWGE ultrasound standardized classification, these cases were classified into 5 types, including type CL (1 case), type CE1 (2 cases), type CE2 (4 cases), type CE3 (3 cases) and type CE4 (3 cases). Gross examination revealed a solitary cyst localized in the liver, varying from 2.7 to 13.5 cm in diameter, and most of them(10/13)were more than 10 cm. Histopathologically, these cysts possessed a thin inner germinal layer and outer adventitial layer, and a central cavity filled with a clear"hydatid"fluid. The germinal layer was continuous and generated brood capsules and protoscoleces. The laminated membranes were clearly demonstrated by elastic fiber and Gomori's stains. Inside the"mother"cyst, there were a varying number of"daughter"vesicles of variable sizes. The inflammatory reaction around the cyst consisted of eosinophils, mononuclear cells immediately next to the cyst layer and sometimes formed granuloma and giant cells resembling the Langhan's type giant cells. The lymphoid cells were positive for CD20 and CD3. The CD68 immunohistochemistry clearly demonstrated epithelioid cells of granuloma in two cases. Moreover, immunohistochemistry revealed plasma cells were locally positive for CD38, IgG and IgG4, but not meeting the criteria for IgG4 related lesion. Conclusions: Hepatic echinococcus granulosus is a zoonotic parasitic disease prevalent in pastoral areas such as Tibet. It is important to understand its clinical features, ultrasound characteristics and histological morphology.

Abstract
Objective: To explore the relationship between polycyclic aromatic hydrocarbons (PAHs), the major component of atmospheric pollutant particulate matter 2.5 (PM2.5) and idiopathic membranous nephropathy (IMN) and its possible mechanisms. Methods: Thirty-five (24 males and 11 females) patients with IMN confirmed by renal biopsy pathology in the First Affiliated Hospital of Zhengzhou University from June to September 2020 were selected as the research group, with an age of (47.3±12.9) years. Meanwhile, patients with secondary membranous nephropathy (SMN, n=10) and minimal-change disease (MCD, n=10) were selected as control group. Blood samples were collected to detect PAHs and heme oxygenase-1 (HO-1), and the relationship of PAHs with clinical indicators and oxidative stress indicator HO-1 was analyzed. Results: Compared with SMN and MCD groups [(2.6±1.7) mg/L and (2.8±1.0) mg/L], the concentration of PAHs in IMN group [(4.1±1.9) mg/L] increased (both P<0.05). The concentration of PAHs was positively correlated with the levels of β2 microglobulin, total cholesterol and 24-hour urine total protein (r=0.509, 0.336, and 0.653, respectively, all P<0.05), but was negatively correlated with the levels of total protein and albumin (r=-0.499,-0.530, respectively, both P<0.05). Additionally, the concentration of PAHs was negatively correlated with the level of HO-1 (r=-0.358, P=0.017). Linear regression analysis showed that the concentration of HO-1 decreased by 1.737 μg/L when the concentration of PAHs increased by 1 mg/L (P=0.035). Conclusion: PAHs have a high level in IMN patients, and may be involved in the occurrence and development of IMN through oxidative stress.

Abstract
Diabetic kidney disease (DKD) has emerged as the primary cause of chronic kidney disease, posing a huge economic and social burden. Therefore, it is urgent to strengthen the prevention and treatment of DKD. However, due to the complex pathogenesis of DKD and the lack of specific and effective intervention targets, there is currently no breakthrough in treatment, thereby causing the continuous increase of end-stage DKD. This review examines several key nodes in the progress of DKD treatment, in order to standardize the clinical treatment, promote the research progress, and improve the prognosis of DKD.

Abstract
Objective: To explore the changes and clinical value of urinary monocyte chemotactic protein 1 (MCP-1), epidermal growth factor (EGF) and their ratio in patients with idiopathic membranous nephropathy (IMN). Methods: A total of 67 IMN patients were enrolled according to kidney biopsy in the Department of Nephrology of the First Affiliated Hospital of Zhengzhou University from January 2017 to December 2018. The patients included 28 males and 39 females, with an average age of (47.6±14.2) years. Eighteen age-and sex-matched healthy controls were also enrolled. Clinical and pathological data, blood and urine samples of all subjects were collected. Urinary MCP-1 and EGF level were detected by enzyme-linked immunosorbent assay (ELISA). And then the levels of urinary MCP-1, EGF and the ratio of EGF/MCP-1 and their correlations with clinicopathology were analyzed. Results: There was no statistical difference of the urine EGF levels between the two groups [8.3(6.0,12.6) vs 8.4(6.5,10.2) ng/mg Cr, P=0.575]. The urine MCP-1 levels of IMN patients were 0.37 (0.21, 0.69) ng/mg Cr, which was statistical significantly higher than those of the control group [0.09 (0.02, 0.19) ng/mg Cr] (P<0.001), while the EGF/MCP-1 ratio was lower than that of the control group [22.2(15.1,36.6) vs 87.6(71.2,132.7), P<0.001]. Urine MCP-1 was negatively correlated with eGFR (r=-0.303, P=0.012), but positively correlated with the urinary ratio of albumin to creatinin (r=0.368, P=0.002). EGF was positively correlated with eGFR (r=0.722, P<0.001), but negatively correlated with the severity of interstitial fibrosis and renal tubular atrophy (IFTA) (r=-0.312, P=0.011). EGF/MCP-1 ratio was positively correlated with eGFR (r=0.693, P<0.001), but negatively correlated with the severity of the urinary ratio of albumin to creatinin and IFTA (r=-0.261, P=0.028 and r=-0.684, P<0.001, respectively). Further multivariate logistic regression analysis showed that EGF/MCP-1 was a protective factor for moderate-to-severe IFTA (OR=0.891, 95%CI: 0.844-0.949, P=0.008). Conclusion: Patients with IMN have elevated urine MCP-1 level and decreased EGF/MCP-1 ratio, which correlate with clinical indicators. In particular, EGF/MCP-1 ratio is independently related to moderate-severe IFTA, and may be a potential clinical biomarker for diagnosis of IMN.

Abstract
Despite thousands of sex-biased genes being found in chickens, the genetic control of sexually dimorphic and left-right asymmetry during gonadal differentiation is not yet completely understood. This study aimed to identify microRNAs (miRNAs), long noncoding RNAs (lncRNAs), messenger RNAs (mRNAs), and signaling pathways during gonadal differentiation in chick embryos (day 6/stage 29). The left and right gonads were collected for RNA sequencing. Sex-biased, side-biased miRNAs, lncRNAs, mRNAs, and shared differentially expressed miRNAs (DEmiRNA)–differentially expressed mRNAs (DEmRNA)–differentially expressed lncRNAs (DElncRNA) interaction networks were performed. A total of 8 DEmiRNAs, 183 DElncRNAs, and 123 DEmRNAs were identified for the sex-biased genes, and 7 DEmiRNAs, 189 DElncRNAs, and 183 DEmRNAs for the side-biased genes. The results of quantitative real-time PCR were generally consistent with the RNA-sequencing results. The study suggested that miRNAs and lncRNAs regulation were novel gene-specific dosage compensation mechanism and they could contribute to left-right asymmetry of chicken, but sex-biased and side-biased miRNAs, lncRNAs, and mRNAs were independent of each other. The competing endogenous RNA (ceRNA) networks showed that 17 target pairs including miR-7b (CYP19A1, FSHR, GREB1, STK31, CORIN, and TDRD9), miR-211 (FSHR, GREB1, STK31, CORIN, and TDRD9), miR-204 (FSHR, GREB1, CORIN, and TDRD9), and miR-302b-5p (CYP19A1 and TDRD9) may play crucial roles in ovarian development. These analyses provide new clues to uncover molecular mechanisms and signaling networks of ovarian development.

Abstract
Objective: To explore the effects and mechanism of rat epidermal stem cells (ESCs) that were treated with exogenous vascular endothelial growth factor (VEGF) on the healing of deep partial-thickness burn wounds in rats. Methods: ESCs were isolated and cultured from the trunk skin of a 3-month-old female Sprague-Dawley (SD) rat. The third passage of cultured cells in the logarithmic growth phase was used in experiments (1)-(3). (1) The cells were routinely cultured in keratinocytes-specified serum-free medium (K-SFM) (the same routine culture condition below). The morphology of cells cultured for 3 and 5 days was observed under the inverted optical microscope. (2) After 24 hours in routine culture, the expression of cell surface markers CD44, CD45, CD11b, and CD11c was detected by flow cytometer, with triplicate samples. (3) Four batches of cells were collected, and each batch was divided into VEGF group or blank control group according to the random number table. The cells in blank control group were routinely cultured, while the cells in VEGF group were cultured in K-SFM containing VEGF in the final mass concentration of 10 ng/mL. The protein expressions of cytokeratin 19 (CK19) and CK10 in cells cultured for 10 days were detected by Western blotting. The Nanog mRNA expression in cells cultured for 0 (immediately), 2, 4, 6, 8, and 10 day (s) was detected by real-time fluorescent quantitative reverse transcription polymerase chain reaction. The absorbance value was detected with cell counting kit-8 in cells cultured for 2, 4, 6, 8, and 10 days. The clone number of more than 50 cells was observed and counted under the optical microscope in cells cultured for 10 days, and the cell colony formation rate was calculated. Three samples at each time point was analysed. (4) Thirty-six 3-month-old SD rats (either male or female) were used for the study, and two deep partial-thickness burn wounds (10 mm in diameter) were created in each rat by pressing a 100 ℃ electric iron plate on symmetric dorsal side. According to the random number table, the injured rats were divided into VEGF+ ESCs group, ESCs alone group, and blank control group, with 12 rats and 24 wounds in each group. From 0 (immediately) to 2 day (s) after injury, 20 μL phosphate buffer solution (PBS) was injected into each wound in the three groups in one time, once a day, with the solution in VEGF+ ESCs group containing 0.8×10(6) cells/mL of ESCs treated by 10 ng/mL VEGF for 10 days, the solution in ESCs alone group containing 0.8×10(6) cells/mL of ESCs without any treatment, and the solution in blank control group being PBS only. On post first injection day (PFID) 0 (immediately), 3, 7, and 14, three rats from each group were taken respectively according to the random number table for wound healing assessment, and the wound healing rates on PFID 3, 7, and 14 were calculated. The mice at each time point were sacrificed with wound tissue harvested for histology, and the skin structure was observed by hematoxylin-eosin staining. Data were statistically analyzed with independent sample t test, analysis of variance for factorial design, least significant difference test, and Bonferroni correction. Results: (1) By day 3 in culture, cells distributed in slowly-growing clusters. By day 5, the clusters were large and round, in which the cells mainly with large and round nuclei and little cytoplasm were observed. The above results were consistent with the morphological characteristics of ESCs. (2) The positive expression rate of CD44 was (94.3±1.2) %, and the expressions of CD45, CD11b, and CD11c were negative. The cells were confirmed as ESCs. (3) Compared with those of blank control group, the protein expression of CK19 in the cells of VEGF group was significantly increased after 10 days in culture (t=3.756, P<0.05), while the protein expression of CK10 was significantly decreased (t=3.149, P<0.05). Compared with those of blank control group, the Nanog mRNA expression in the cells cultured for 0 and 2 day (s) and absorbance values of the cells cultured for 2 and 4 day (s) were not significantly changed in VEGF group (t=0.58, 0.77, 0.53, 3.02, P>0.05), while the Nanog mRNA expression in the cells cultured for 4, 6, 8, and 10 days and absorbance values of the cells cultured for 6, 8, and 10 days were significantly increased in VEGF group (t=6.34, 5.00, 5.58, 4.61, 5.65, 10.78, 15.51, P<0.01). After 10 days in culture, the cell colony-forming rate in VEGF group was (56.4±1.3) %, significantly higher than (31.5±1.3) % of blank control group (t=13.96, P<0.01). (4) The burn wounds of rats in the three groups were confined to the superficial dermis of the skin on PFID 0. On PFID 3, normal skin tissue at wound margins slightly contracted in the rats of VEGF+ ESCs group, which was earlier than that in the other two groups. On PFID 7, the newly generated epidermis covered most parts of the rat wounds in VEGF+ ESCs group, and some of the epithelium crawled around the rat wounds in ESCs alone group, but no obvious epithelialization was observed in the rat wounds in blank control group. On PFID 14, the rat wounds in VEGF+ ESCs group were basically healed, while some parts of the rat wounds were unhealed in ESCs alone group, and most parts of the rat wounds were unhealed in blank control group. On PFID 3, the wound healing rates of rats in the three groups were similar (P>0.05). On PFID 7 and 14, the wound healing rates of rats in ESCs alone group, respectively (26.0±2.0) % and (64.4±4.7) %, were obviously higher than (12.4±1.1) % and (29.1±3.3) % of blank control group (P<0.01), all of which were obviously lower than (41.0±2.4) % and (91.3±3.5) % of VEGF+ ESCs group (P<0.01). On PFID 3, infiltration of a large number of inflammatory cells were observed in the rat wounds in VEGF+ ESCs group, which was earlier than those in the other two groups. On PFID 7, a large number of endothelial cells were observed in the rat wounds in VEGF+ ESCs group, while proliferation of a few endothelial cells were observed in the rat wounds in ESCs alone group, and a large number of inflammatory cells infiltrated the rat wounds in blank control group. On PFID 14, the newly generated epidermal cells covered nearly all the rat wounds in VEGF+ ESCs group and most parts of the rat wounds in ESCs alone group, while a large number of endothelial cells were observed and the newly generated epidermal cells covered some parts of the rat wounds in blank control group. Conclusions: ESCs of rats treated with exogenous VEGF can promote the healing of deep partial-thickness burn wounds in rats, which may be related to VEGF's roles in promoting the proliferation of ESCs and reducing its differentiation level, so as to maintain the potency of stem cells.

Abstract
Transesophageal echocardiography(TEE) is valuable in intensive care unit (ICU) because its application meets the requirements of diagnosis and treatment of critically ill patients.However, the current application has not fully adapted to the specialty of critical care. TEE could be more valuablein ICU when used with a new way that under the guidance of the theory of critical care and embedded into the treatment workflow. We have expanded and improved the application of traditional TEE and integrated the concept of critical care, established the concept of transesophageal echocardiography for critical care (TEECC). Chinese Critical Ultrasound Study Group (CCUSG) organized experts in the area to form the consensus based the previous studiesand the long term practice of critical care ultrasound and TEE, aiming at clarifying the nature and characteristics of TEECC, promoting the rational and standardized clinical application and the coming researches.The consensus of Chinese experts on clinical application of TEECC (2019) were 33 in total, of whichthe main items were as follows: (1) TEECC is a significant means, which is expanded and improved from the traditional transesophageal echocardiography according to characteristics of critically ill patients and is applied in ICU based on critically clinical scenarios and requirements by the critical care physician, to promote visualized, refined and precisely management of critically ill patients.(2) TEE possesses distinctive superiority in implementation in ICU. It has characteristics of images with good quality, operations with good stability and low-dependent of operators, monitoring with continuity, and visualization with all-dimensional and detail of heart and blood vessels.(3)As a means of refined monitoring that could resulted in precise diagnosis and treatment, TEECC expands the dimension of intensive monitoring and improves the performance of critical care. (4) Indications of TEECC application include clinical etiological searching and invasive procedures guiding when it acted as a traditional role; and also refined hemodynamic monitoring based on critical care rationale and over-all management under specific critical clinical scenarios. (5) TEE and TTE assessments are complementary; they are not alternative. Integrated assessment of TTE and TEE is required under many critical clinical scenarios.(6) TEE should be a necessary configuration in ICU. (7) All-round and significant information regarding to the mechanism of acute circulatory disorders can be provided by TEECC; it is a non-substitutable means of identifying the causes of shock under some special clinical scenarios. (8) Focal extracardiac hematoma can be accurately and rapidly detected by TEE in patients with open-thoracic cardiac surgery or severe chest trauma when highly suspected pericardial tamponade.(9) The priority of pathophysiologic mechanism of septic shock can be rapidly and accurately identified by TEE; even if its pathophysiological changes are complex, including hypovolemia and/or vasospasm and/or left and right heart dysfunction. (10) Causes of hemodynamic disorders can be rapidly and qualitatively evaluated so that the orientation of treatment can be clarified by TEECC. (11) A full range of quantitative indicators for refined hemodynamic management in critically ill patients can be provided by TEECC. (12) TEECC helps to accurately assess volume status and predict fluid responsiveness.(13) TEECC is specially suitable for accurate quantitative assessment of cardiac function.(14) Mini TEE provides long-term continuous hemodynamic monitoring. (15) Standard views are easy to be acquired by TEECC, which is a premise for accurate and repeatable measurements, and a guarantee for assessment of effect and risk of therapy. (16) Compared with invasive hemodynamic monitoring, TEECC is minimally invasive, with low infection risk and high safety.(17) In patients with acute cor pulmonale (ACP) under condition of right ventricular dysfunction and low cardiac output, TEECC is a key tool for assessment. (18) TEECC should be implemented actively when suspicious of left to right shunt in critically ill patients who occurred hypotension that hard to explain the cause. (19) TEECC should be implemented actively when suspicious of right to left shunt in critically ill patients who occurred hypoxemia that hard to explain the cause. (20) TEECC is preferred in hemodynamics monitoring under prone position of ventilated patients.(21) TEECC is an imperative means to achieve over-all management of extracorporeal membrane oxygenation (ECMO) therapy, especially for all-round hemodynamic monitoring. (22) Three basic views is recommended to be used to simplify TEE assessment during cardiac arrest so that reversible causes could be identified, and resuscitation could be guided. (23) The flow related echodynamic evaluation (TEECC-FREE) workflow is preferred in refined hemodynamics monitoring and therapy. (24) Simple workflow of TEECC could be implemented in special critical clinical scenarios. (25) Application of TEECC is highly secure; however, impairments of procedure should also be alert by operators. (26) Pitfalls in application of TEE should be paid attention to by the critical care physician. (27) Timely and rationally application of TEECC is in favor of diagnosis and treatment of critically ill patients and may improve the prognosis.

Abstract
The skin pathologic scar is a skin fibrous proliferative disease characterized by abnormal proliferation of fibroblasts and overdeposition of extracellular matrix. Unclarity of genesis and development mechanism is the main reason that restricts its diagnosis and treatment. In recent years, it has been found that microRNAs play important roles in the regulation mechanism of pathological scars. The competing endogenous RNAs (ceRNAs) have microRNA response elements which can be competitively combined with microRNAs through sponge adsorption. Through the mutual regulation of RNAs, ceRNAs regulate the expression of target gene and participate in the development of disease. Based on the ceRNA hypothesis, this paper systematically reviews the biological functions and clinical significance of ceRNAs in pathological scars of skin, and discusses the role of ceRNAs and " RNA-microRNA-RNA" regulation network in pathologic scars. The ceRNA therapy may become a new model therapy for skin scars in the future.

Abstract
Objective: To explore the SNP effects of patatin-like phospholipase domain which containing 3 (PNPLA3), transmembrane 6 superfamily member 2 (TM6SF2) gene, environmental effects of smoking, alcohol drinking and interaction between gene-gene, gene-environment and drinking-smoking on hepatitis B virus-associated hepatocellular carcinoma (HBV-HCC). Methods: We collected anticoagulant peripheral blood from patients of HBV-HCC, chronic hepatitis B (CHB), liver cirrhosis (LC) and from healthy controls to detect the single nucleotide polymorphism (SNP) of patatin-like phospholipase domain containing 3 (PNPLA3) gene loci rs738409 and transmembrane 6 superfamily member 2 (TM6SF2) gene loci rs58542926, using the flight mass spectrometry method. The optimal assignment value of gene polymorphisms was defined by using the online SNP stats. Hardy-Weinberg (H-W) balance was tested for SNP. Effects of the genetic and environmental factors to HBV-HCC were analyzed by using the multiple classification logistic regression method. The gene-gene, gene-smoking and alcohol drinking interaction effects were investigated by Fork-Life analysis and binary logistic regression methods. Results: The frequency distribution of CHB group rs738409 loci seemed not in conformity with the H-W balance (χ(2)=11.980, P<0.005). Two loci frequency distributions in the other groups were all in accordandce with the H-W balance. After adjusting for influences on age and sex and comparing to the healthy group, the rs58542926 mutation appeared as OR=1.659, 95%CI: 1.026-2.684, P=0.039, in the HBV-HCC group. When comparing to CHB group, the HBV-HCC group presented that drinking as OR=1.680, 95%CI: 1.121-2.519, P=0.012. When comparing to the LC group, the ORs of drinking and smoking were 1.539 (1.071-2.213) and 1.453 (1.005-2.099) respectively, in the HBV-HCC group. When comparing to the CHB+LC group, interactions between the HBV-HCC group were found rs738409 and rs58542926 on additive model OR=1.548 (U=1.885, P=0.029) and OR=1.658 (P=0.024) on logistic regression model while drinking was rs738409 on interaction additive model with OR=1.811(U=1.965, P=0.024). As for drinking and mutation of rs738409, the multiplication model of logistic regression showed no statistically significant differences. Interaction between smoking and drinking appeared as OR=1.756 (P<0.001) in the logistics regression multiplication model. Conclusions: Factors as mutation of TM6SF2, smoking and drinking all appeared as risk factors for HBV-HCC. Mutations of both PNPLA3 and TM6SF2, together with smoking and drinking all served as risk factors for HBV-HCC. However, the mutation of single PNPLA3 appeared as a protective factor on HBV-HCC.

Objective: The relationship of venous-to-arterial CO(2) difference(Pv-aCO(2))/arterial-central venous O(2) difference (Ca-vO(2)) ratio, peripheral perfusion index(PI) and lactate clearance(LC) were investigated during resuscitation in septic patients. And, the meaning of the combination PI and Pv-aCO(2)/Ca-vO(2) ratio to interpret incoherence of lactate clear was explored. Methods: The patients with sepsis were prospectively observed, who admitted to critically care medicine department of Peking Union Medical College Hospital. The hemodynamic parameters, simultaneous arterial and central venous blood gas analysis and PI were obtained at the enrollment (T0) and 8 hours (T8) during resuscitation. The lactate clearance was defined as 8h-LC≥10% and non-lactate clearance was defined as 8h-LC ≤ 10%. Additionally, the patients were divided as three sub-groups according to the PI value at T8: the normalized PI group with PI≥1.4,the mild impaired PI with 1.4<PI<0.6 and severe impaired PI with PI≤0.6. Results: A total of 84 patients were enrolled in this study. There was no significant difference in Pv-aCO(2)/Ca-vO(2) ratio in the three groups. However, the PI≤0.6 group had a significantly higher Pv-aCO(2) than other groups. Moreover, the patients with non-lactate clearance (13/32) had a higher Pv-aCO(2)/Ca-vO(2) ratio than the patients with lactate clearance in PI≥1.4 group (1.9±0.7 vs. 1.3±1.0, P=0.01). Multivariate analysis showed both Pv-aCO(2)/Ca-vO(2) ratio [Exp(B) 2.235, 95% CI 1.232-4.055, P=0.008] and acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) [Exp (B) 1.087, 95%CI 1.022-1.156, P=0.008] were independent risk factor of non-lactate clearance. 8h-PI was significantly negative correlated with the 8 h Pv-aCO(2) gap (r=-0.311, P=0.004), but not significantly with Pv-aCO(2)/Ca-vO(2) ratio (r=-0.094, P=0.385). Conclusions: Both high Pv-aCO(2)/Ca-vO(2) ratio and low PI were related to non-lactate clearance after resuscitation in sepsis. Combined PI and Pv-aCO(2)/Ca-vO(2) ratio could interpret incoherence of latacte clearance after resuscitation.

Abstract
Objective: To investigate the expression of triggering receptor expressed on myeloid cells receptor-1 (TREM-1) in plasma and bronchoalveolar lavage fluid (BALF) and its correlation with Galactomannan, IFNγ, IL-6 and IL-10 in Aspergillus infected mice. Methods: Cyclophosphamide(CTX) was intraperitoneally injected and fumigatus spore suspension was inhaled by nose to establish the immunocompromised invasive pulmonary aspergillosis(IPA) mouse model.Healthy controls, immunocompromised only and IPA only groups were also established. Each group had 6 mice. After inoculation, mice were sacrificed. Lung tissue specimens, BALF, and plasma samples were collected. Plasma and BALF soluble TREM-1 (sTREM-1), Galactomannan, IFNγ, IL-6, and IL-10 were detected by ELISA. Results: Positive Aspergillus fumigatus was found by tissue culture in the lung. Infiltration of inflammatory cells, blood congestion and interstitial lung tissue injury were observed in histological sections of both IPA and immunocompromised IPA mice. Compared to IPA group [(453.78±74.18) ng/L, P<0.001; (10.21±1.46) ng/L, P<0.001] and control group [(245.16±65.85) ng/L, P<0.001; (6.60±3.74) ng/L, P<0.001], the plasma and BALF sTREM-1 significantly increased in immunocompromised IPA group [(1 537.64±359.52) ng/L; (20.12±2.72) ng/L]. Compared to control group, both the BALF sTREM-1 in IPA group (P=0.041) and the plasma and BALF Galactomannan, IFNγ, IL-6, and IL-10 levels in IPA and immunocompromised IPA groups were significantly higher (P<0.01). Pearson correlation analysis showed that plasma and BALF sTREM-1 were significantly correlated with Galactomannan (r=0.83, P<0.001; r=0.82, P<0.001), IFNγ (r=0.79, P<0.001; r=0.61, P<0.01), IL-6 (r=0.81, P<0.001; r=0.66, P<0.01), and IL-10 (r=0.70, P=0.001; r=0.54, P=0.02). Conclusions: Plasma and BALF sTREM-1 appears highly expressed in Aspergillus infected mice. sTREM-1 in mice plasma and BALF is closely correlated with Galactomannan, IFNγ, IL-6, and IL-10 levels, which suggests that sTREM-1 has great diagnostic value during invasive fungal infection.

Abstract
Critical ultrasonography(CUS) is different from the traditional diagnostic ultrasound, the examiner and interpreter of the image are critical care medicine physicians. The core content of CUS is to evaluate the pathophysiological changes of organs and systems and etiology changes. With the idea of critical care medicine as the soul, it can integrate the above information and clinical information, bedside real-time diagnosis and titration treatment, and evaluate the therapeutic effect so as to improve the outcome. CUS is a traditional technique which is applied as a new application method. The consensus of experts on critical ultrasonography in China released in 2016 put forward consensus suggestions on the concept, implementation and application of CUS. It should be further emphasized that the accurate and objective assessment and implementation of CUS requires the standardization of ultrasound image acquisition and the need to establish a CUS procedure. At the same time, the standardized training for CUS accepted by critical care medicine physicians requires the application of technical specifications, and the establishment of technical specifications is the basis for the quality control and continuous improvement of CUS. Chinese Critical Ultrasound Study Group and Critical Hemodynamic Therapy Collabration Group, based on the rich experience of clinical practice in critical care and research, combined with the essence of CUS, to learn the traditional ultrasonic essence, established the clinical application technical specifications of CUS, including in five parts: basic view and relevant indicators to obtain in CUS; basic norms for viscera organ assessment and special assessment; standardized processes and systematic inspection programs; examples of CUS applications; CUS training and the application of qualification certification. The establishment of applied technology standard is helpful for standardized training and clinical correct implementation. It is helpful for clinical evaluation and correct guidance treatment, and is also helpful for quality control and continuous improvement of CUS application.

Abstract
Objective: To evaluate the value of microcirculation and oxygen metabolism evaluation (MicrOME) in acute kidney injury(AKI) evaluation in patients with septic shock after resuscitation. Methods: Consecutive patients with septic shock after resuscitation and mechanical ventilation were enrolled from October 2016 to February 2017 in ICU at Peking Union Medical College Hospital.Patients were divided into 3 groups based on 10 min transcutaneous oxygen challenge test transcutaneous partial pressure of oxygen(PtcO(2))and venoarterial pressure of carbon dioxide difference (Pv-aCO(2)) /arteriovenous O(2) content difference (Ca-vO(2)) by blood gas analysis, i.e. group A [ΔPtcO(2)>66 mmHg(1 mmHg=0.133 kPa) and Pv-aCO(2)/Ca-vO(2)≤1.23], group B (ΔPtcO(2)≤66 mmHg), group C (ΔPtcO(2)>66 mmHg and Pv-aCO(2)/Ca-vO(2)>1.23). Heart rate,mean arterial pressure,central venous pressure,noradrenaline dose,lactate,Pv-aCO(2),Ca-vO(2), lactate clearance, central venous oxygen saturation(ScvO(2)) and liquid equilibrium were assessed after resuscitation.AKI staging based on Kidney Disease Global Improving Outcomes (KDIGO) clinical practice guideline was analyzed. The predictive value of lactate, ScvO(2), Pv-aCO(2)/Ca-vO(2) to progression of AKI after resuscitation was determined using receiver operating characteristic(ROC)curve analysis. Results: A total of 49 septic shock patients were enrolled including 30 males and 19 females with mean age of (61.10±17.10)years old.There were 19 patients in group A,21 patients in group B, and 9 patients in group C. Acute physiology and chronic health evaluation Ⅱ score was 20.92±7.19 and sequential organ failure assessment score 12.02±3.28. There were 4 patients with AKI and 1 progressed in group A, 11 patients with AKI and 2 progressed in group B, 6 patients with AKI and 4 progressed in group C. The cutoff value of Pv-aCO(2)/Ca-vO(2) was equal or more than 2.20 for predicting progression of AKI, resulting in a sensitivity of 85.7% and a specificity of 73.8%. Conclusion: MicrOME is a significant parameter to predict the progression of AKI in patients with septic shock after resuscitation. Pv-aCO(2)/Ca-vO(2) is also a good predictive factor.

Abstract
OBJECTIVE To analyze the stress distribution in the periodontal ligament (PDL) under different loading conditions at the stage of space closure by 3D finite element model of customized lingual appliances. METHODS The 3D finite element model was used in ANSYS 11.0 to analyze the stress distribution in the PDL under the following loading conditions: (1) buccal sliding mechanics (0.75 N,1.00 N,1.50 N), (2) palatal sliding mechanics (0.75 N,1.00 N,1.50 N), (3) palatal-buccal combined sliding mechanics (buccal 1.00 N + palatal 0.50 N, buccal 0.75 N + palatal 0.75 N, buccal 0.50 N+ palatal 1.00 N). The maximum principal stress, minimum principal stress and von Mises stress were evaluated. RESULTS (1) buccal sliding mechanics(0.75 N,1.00 N,1.50 N): maximum principal stress: at the initial of loading, maximum principal stress, which was the compressed stress, distributed in labial PDL of cervix of lateral incisor, and palatal distal PDL of cervix of canine. With increasing loa-ding, the magnitude and range of the stress was increased. Minimum principal stress: at the initial of loading, minimum principal stress which was tonsil stress, distributed in palatal PDL of cervix of lateral incisor and mesial PDL of cervix of canine. With increasing loading, the magnitude and range of minimum principal stress was increased. The area of minimum principal stress appeared in distal and mesial PDL of cervix of central incisor. von Mises stress:it distributed in labial and palatal PDL of cervix of lateral incisor and distal PDL of cervix of canine initially. With increasing loading, the magnitude and range of stress was increased towards the direction of root. Finally, there was stress concentration area at mesial PDL of cervix of canine. (2) palatal sliding mechanics(0.75 N,1.00 N,1.50 N): maximum principal stress: at the initial of loading, maximum principal stress which was the compressed stress, distributed in palatal and distal PDL of cervix of canine, and distal-buccal and palatal PDL of cervix of lateral incisor. With increasing loading, the magnitude and range of the stress was increased. Minimum principal stress: at the initial of loading, minimum principal stress which was tonsil stress, distributed in distal-interproximal PDL of cervix of lateral incisor and mesial-interproximal PDL of cervix of canine. With increasing loading, the magnitude and range of the stress was increased.von Mises stress: von Mises stress distributed in palatal and interproximal PDL of cervix of canine. With increasing loading, the magnitude and range of stress was increased. Finally, von Mises stress distributing area appeared at distal-palatal PDL of cervix of canine. (3) palatal-buccal combined sliding mechanics: maximum principal stress: maximum principal stress still distributed in distal-palatal PDL of cervix of canine. Minimum principal stress: minimum principal stress distributed in palatal PDL of cervix of lateral incisor when buccal force was more than palatal force. As palatal force increased, the stress concentrating area transferred to mesial PDL of cervix of canine.von Mises stress: it was lower and more well-distributed in palatal-buccal combined sliding mechanics than palatal or buccal sliding mechanics. CONCLUSION Using buccal sliding mechanics,stress majorly distributed in PDL of lateral incisor and canine, and magnitude and range of stress increased with the increase of loading; Using palatal sliding mechanics, stress majorly distributed in PDL of canine, and magnitude and range of stress increased with the increase of loading; With palatal-buccal combined sliding mechanics, the maximum principal stress distributed in the distal PDL of canine. Minimum principal stress distributed in palatal PDL of cervix of lateral incisor when buccal force was more than palatal force. As palatal force was increasing, the minimum principal stress distributing area shifted to mesial PDL of cervix of canine. When using 1.00 N buccal force and 0.50 N palatal force, the von Mises stress distributed uniformly in PDL and minimal stress appeared.

Abstract
Objective: To investigate doctors' and nurses' perceptions and implementation of delirium management in intensive care unit. Methods: A total of 197 doctors and nurses in 2 general ICUs and 3 special ICUs at Peking Union Medical College Hospital finished a self-designed questionnaire of delirium management. Results: There were 47 males and 150 females, 43 doctors and 154 nurses who participated in the survey.One hundred and twenty five participators were from general ICU and the others from special ICU. The ICU staff had a significant difference on the perceptions and implementation of delirium management(P< 0.001) including. Doctors and nurses scored lowest in "family engagement and empowerment" and "sleep management" with (4.620±2.393) and (5.430±2.153) respectively. There was a significant difference between nurses and doctors in the management of analgesia and sedation (P< 0.05).Doctors and nurses from different ICUs had significant discrepancy in the implementation of "delirium assessment" (P< 0.05). Conclusions: The ICU staff should improve the perceptions and the implementation of delirium management,especially in special ICUs. Delirium management should be included as a routine care in ICU to improve patients' outcome.

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