Background/Aims: Metabolic syndrome is common in patients with acute pancreatitis and its components have been reported to be associated with infectious complications. In this post hoc analysis, we aimed to evaluate whether metabolic abnormalities impact the effect of immuneenhancing thymosin alpha-1 (Tα1) therapy in acute necrotizing pancreatitis (ANP) patients. Methods: All data were obtained from the database for a multicenter randomized clinical trial that evaluated the efficacy of Tα1 in ANP patients. Patients who discontinued the Tα1 treatment prematurely were excluded. The primary outcome was 90-day infected pancreatic necrosis (IPN) after randomization. Three post hoc subgroups were defined based on the presence of hyperglycemia, hypertriglyceridemia, or both at the time of randomization. In each subgroup, the correlation between Tα1 and 90-day IPN was assessed using the Cox proportional-hazards regression model. Multivariable propensity-score methods were used to control potential bias. Results: Overall, 502 participants were included in this post hoc analysis (248 received Tα1 treatment and 254 received matching placebo treatment). Among them, 271 (54.0%) had hyperglycemia, 371 (73.9%) had hypertriglyceridemia and 229 (45.6%) had both. Tα1 therapy was associated with reduced incidence of IPN among patients with hyperglycemia (18.8% vs 29.7%: hazard ratio, 0.80; 95% confidence interval, 0.37 to 0.97; p=0.03), but not in the other subgroups. Additional multivariate regression models using three propensity-score methods yielded similar results. Conclusions Among ANP patients with hyperglycemia, immune-enhancing Tα1 treatment was associated with a reduced risk of IPN (ClinicalTrials.gov, Registry number: NCT02473406).

To investigate the effects of streptavidin and dimethylsilicone oil on the detection rate of microscopic lesions under gastroscopy, a total of 353 patients who underwent painless gastroscopy were categorized into the experimental group (given streptavidin combined with sodium bicarbonate, n=176) and the control group (given dimethylsilicone oil combined with sodium bicarbonate, n=177). Clinical indexes such as visual field clarity, examination duration, number of rinses, detection rate of micro lesions, early cancer detection rate and incidence of adverse reactions were recorded in the gastroscopy examination of the two groups. The experimental and control groups were compared in terms of visual field clarity (1.84±0.51 points VS 2.15±0.48 points, t=-5.900), fundus mucus properties (1.04±0.43 points VS 1.46±0.76 points, t=-6.347) and number of rinses (0.76±0.66 times VS 1.18±0.72 times, t=-5.628) with significant differences ( P<0.001). The examination time in the experimental group was slightly higher than that in the control group (10.01±4.40 min VS 8.98±4.22 min, t=2.239, P=0.026). The detection rate of microscopic lesions was significantly higher in the experimental group than that in the control group [97.73%(172/176) VS 91.53%(162/177), χ2=6.665, P=0.010]. There was no significant difference in the detection rate of inflammatory hyperplasia, polyps, precancerous lesions or cancer between the experimental group and the control group ( P>0.05). There was no preoperative drinking discomfort in either group, and 4 cases of intraoperative choking occurred in each of the experimental and the control group with no significant difference ( P>0.999). No postoperative adverse reaction occurred in either group. Taking streptavidin before operation could significantly improve visual field clarity and the detection rate of microscopic lesions, which helps to detect early lesions in stomach.

Objective:To evaluate the effect of invasive arterial blood pressure (IBP) monitoring on the prognosis of patients with sepsis.Methods:Patients with sepsis from the MIMIC-Ⅳ database were collected and divided into IBP and non-invasive blood pressure monitoring (NIBP) groups according to whether IBP monitoring was performed. Baseline variables that were considered clinically relevant or showed a univariate relationship with the outcome were entered into a multivariate logistic regression model as covariates.Propensity score matching(PSM) and inverse probability of treatment weighing(IPTW) were used to adjust confounders to ensure the robustness of findings.Subgroup analysis were conducted to evaluate the effect of differences in IBP onset and duration on outcome.Results:The 28-day mortality is lower in IBP group compared with NIBP group( OR=0.54, 95% CI 0.46-0.62, P<0.001), the conclusion maintain robust after PSM and IPTW.Then we conducted a series of logistic regression regarding to different initial IBP time(<24 h,24 h-48 h,>48 h) and the initial IBP time within 24 h showed the same results compared to primary outcoms( OR=0.42, 95% CI: 0.36-0.49, P<0.001). IBP duration varied (≤1day, ≤2days, ≤3days, ≤4days, >4days) all showed a statistically significant association with decreased 28-day mortality in the IBP group. Conclusions:IBP is associated with decreased 28-day mortality in patients with sepsis, and the optimal time of IBP is within 24 hours.

Objective:To investigate the urine output threshold of acute kidney injury in patients with acute pancreatitis(AP) and to guide early fluid therapy.Methods:The clinical data of AP patients from Medical Information Mart for Intensive Care Ⅳ (MIMIC-Ⅳ) were collected. The 24-h urine output rate [24-h urine output·kg-1·24-h-1, 24-UR mL/ (kg·h) ] and 48-h urine output rate [48-h urine output·kg-1·48-h-1, 48-UR mL/ (kg·h) ] were calculated, and according to the occurrence of acute kidney injury within 7 days (7-AKI), AP patients were divided into the 7-AKI group and non-7-AKI group. The receiver operating characteristic (ROC) curve was drawn to evaluate the predictive value of 24-UR and 48-UR on 7-AKI in AP patients. 24-UR and 48-UR were grouped according to the optimal cut-off value obtained from the ROC curve. Logistic regression was used to analyze the risk factors of 7-AKI, and Kaplan-Meier (KM) survival curve was drawn to analyze the effect of 24-UR and 48-UR on in-hospital mortality of AP patients.Results:A total of 713 AP patients were included, ROC curve analysis showed that the area under the ROC curve (AUC) of 24-UR in predicting 7-AKI in AP patients was 0.76. Based on the maximum Youden index, the cut-off value of 24-UR was 0.795 mL/ (kg·h) , and the AUC of 48-UR was 0.78 and the cut-off value of 48-UR was 0.975 mL/ (kg·h) . Logistic regression analysis showed that 24-UR≤0.795 mL/ (kg·h) was an independent risk factor for 7-AKI compared with 24-UR>0.795 mL/ (kg·h) ( OR: 4.22, 95% CI:1.50-11.85, P=0.006). Similarly, compared with 48-UR>0.975 mL/ (kg·h) , 48-UR0.975 mL/ (kg·h) was an independent risk factor for 7-AKI ( OR: 3.75, 95% CI: 1.45-9.72, P=0.007). The KM survival curve showed that the cumulative in-hospital survival rate in the high 24-UR group was higher than that in the low 24-UR group. Conclusions:24-UR can be used to guide early fluid therapy in AP patients.

Purpose: miR-205 is a tumor suppressor and plays an important role in tumor invasiveness. However, the role of miR-205 in human gastric cancer (GC) epithelial-mesenchymal transition (EMT) remains unclear. The aim of this study was to investigate the molecular mechanism of miR-205 in the regulation of EMT in GC invasion. Materials and Methods: Quantitative polymerase chain reaction (qPCR) was used to detect the expression of miR-205 in GC. Further, the correlation between the pathological parameters and prognosis of GC was statistically analyzed. A transwell model was used to evaluate the effect of miR-205-3p on the invasion and migration of GC cells. qPCR, western blotting, and luciferase assay were performed to analyze the relationship and target effects between miR-205-3p and the expression of zinc finger electron box binding homologous box 1 (ZEB1) and 2 (ZEB2). Results: We found that the levels of miR-205-3p were significantly lower (P<0.05) in GC tissues than in matched normal tissues. Additionally, the expression of miR-205-3p was related to the tumor invasion depth, lymph node metastasis, lymph node invasion, and tumor, node, metastasis stage. Patients with lower miR-205-3p expression levels in the tumors had a poorer prognosis. The in vitro assays indicated that miR-205-3p could affect the invasion ability and EMT of GC cells by targeting the expression of both ZEB1 and ZEB2. Conclusions miR-205-3p promotes GC progression and affects the prognosis of patients by targeting both ZEB1 and ZEB2 to directly influence EMT.

Objective To investigate the value of the difference between peripheral arterial and venous blood gas analysis for the prognosis of patients with septic shock after resuscitation.Methods Patients with septic shock aged 18 to 80 years admitted to intensive care unit (ICU) of Affiliated Hospital of Integrated Traditional Chinese and Western Medicine, Nanjing University of Chinese Medicine from May 2016 to December 2017 were enrolled. The peripheral arterial blood and peripheral venous blood gas analysis were measured simultaneously after the early 6 hours resuscitation, including pH, partial pressure of oxygen (PO2), partial pressure of carbon dioxide (PCO2), base excess (BE), bicarbonate (HCO3-) and lactate (Lac) level, and the difference values between peripheral arterial and venous blood were calculated. According to the 28-day survival, the patients were divided into survival group and death group. Multiple Logistic regression analysis was used to analyze the risk factors of death, and the receiver operating characteristic curve (ROC) was used to analyze the prognostic value of blood gas analysis parameters for prognosis.Results A total of 65 patients with septic shock resuscitation were enrolled in the study, 35 survived while 30 died during the 28-day period. ① There was no significant difference in gender, age, and mean arterial pressure (MAP), central venous pressure (CVP), central venous oxygen saturation (ScvO2) and norepinephrine (NE) dose between the two groups.② The arterial and venous Lac, the difference of Lac (ΔLac) and PCO2 (ΔPCO2) between arterial and venous blood in death group were significantly higher than those in survival group [arterial Lac (mmol/L): 7.40±3.10 vs. 4.82±2.91, venous Lac (mmol/L): 9.17±3.27 vs. 5.81±3.29, ΔLac (mmol/L): 1.77±0.54 vs. 0.99±0.60, ΔPCO2 (mmHg, 1 mmHg =0.133 kPa): 9.64±5.08 vs. 6.70±3.71, allP < 0.01], and there was no significant difference in the other arterial and venous blood gas analysis index and its corresponding differential difference between two groups. ③ Multiple Logistic regression analysis showed that ΔPCO2 [β = 0.247, odd ratio (OR) = 1.280, 95％ confidential interval (95％CI) = 1.057-1.550,P = 0.011], and ΔLac (β = 2.696,OR = 14.820, 95％CI = 2.916-75.324,P = 0.001) were the independent risk factors for the prognosis of septic shock. ④ It was shown by ROC curve analysis that arterial blood Lac, ΔLac andΔPCO2 had predictive value on prognosis of septic shock, the area under ROC curve (AUC) was 0.792, 0.857, 0.680, respectively (allP < 0.05). When the best cut-off value of arterial Lac was 4.00 mmol/L, the sensitivity was 100％, and the specificity was 62.86％ for predictor of death in 28-day; when the best cut-off value of ΔLac was 1.25 mmol/L, the sensitivity was 93.33％, and the specificity was 68.57％ for predictor of death in 28-day; when the best cut-off value of ΔPCO2 was 4.35 mmHg, the sensitivity was 83.33％, and the specificity was 37.14％ for predictor of death in 28-day.Conclusions Compared to other parameters, the difference between peripheral arterial and venous blood gas analysis, ΔPCO2 and ΔLac had the best correlation with the prognosis of septic shock. The ΔPCO2 and ΔLac are the independent prognostic predictors for 28-day survival.

OBJECTIVE: To evaluate the prognostic value of the difference between peripheral venous and arterial partial pressure of carbon dioxide in patients with septic shock following early resuscitation. METHODS: This prospective study was conducted among the patients with septic shock treated in our department during the period from May, 2017 to May, 2018. Peripheral venous, peripheral arterial and central venous blood samples were collected simultaneously and analyzed immediately at bedside after 6-h bundle treatment. Arterial blood lactate concentration (Lac) and the arterial (PaCO), peripheral venous (PpvCO) and central venous partial pressure of carbon dioxide (PcvCO) were recorded. The differences between PpvCO and PaCO (Ppv-aCO) and between PcvCO and PaCO (Pcv-aCO) were calculated. Pearson correlation analysis was used to test the agreement between Pcv-aCO and Ppv-aCO. Multivariable logistic regression analysis was performed to analyze the possible risk factors for 28-day mortality, and the receiver-operating characteristic curve (ROC) was plotted to assess the prognostic values of these factors for 28-day mortality. RESULTS: A total of 62 patients were enrolled in this study, among who 35 survived and 27 died during the 28-day period. Compared with the survivor group, the patients died within 28 days showed significantly higher Acute Physiology and Chronic Health Evaluation Ⅱ (APACHE Ⅱ) score (24.2±6.0 20.5±4.9, =0.011), sequential organ failure assessment (SOFA) score (14.9±4.7 12.2±4.5, =0.027), PcvaCO (5.5±1.6 7.1±1.7, < 0.001), PpvaCO (7.1±1.8 10.0±2.7, < 0.001), and arterial lactate level (3.3±1.2 4.2±1.3, =0.003) after 6-h bundle treatment. Pearson correlation analysis showed that Ppv-aCO was significantly correlated with Pcv-aCO (=0.897, R= 0.805, < 0.001). Multiple logistic regression analysis identified Ppv-aCO (β=0.625, =0.001, OR=1.869, 95% CI: 1.311-2.664) and lactate level (β=0.584, =0.041, OR=1.794, 95%CI: 1.024-3.415) as the independent risk factors for 28-day mortality. The maximum area under the ROC (AUC) of Ppv-aCO was 0.814 (95%CI: 0.696- 0.931, < 0.001), and at the best cut- off value of 9.05 mmHg, Ppv-aCO had a sensitivity of 70.4% and a specificity of 88.6% for predicting 28-day mortality. The AUC of lactate level was 0.732 (95%CI: 0.607-0.858, =0.002), and its sensitivity for predicting 28-day mortality was 70.4% and the specificity was 74.3% at the best cut-off value of 3.45 mmol/L; The AUC of Pcv-aCO was 0.766 (95%CI: 0.642-0.891, < 0.001), and its sensitivity was 66.7% and the specificity was 80.0% at the best cut-off value of 7.05 mmHg. CONCLUSIONS A high Ppv-aCO after early resuscitation of septic shock is associated with poor outcomes. Ppv-aCO is well correlated with Pcv-aCO and can be used as an independent indicator for predicting 28-day mortality in patients with septic shock.

Objective: To evaluate the clinical effect of a digital whole-process surgical guide for immediate implantation in the molar area. Methods : Twenty-six patients with molar extraction plans were accepted for preoperative CBCT and model construction. Computer software was used to design the ideal three-dimensional position of the implant. The control group of 13 patients underwent immediate implantation with a free hand operation, whereas the experimental group of 13 patients underwent preparation and implant insertion under the guidance of a surgical guide. Bone grafting was performed, and a good initial stability was achieved. After 5 to 6 months, osseointegration was achieved, and the final restoration was delivered. After surgery, the accuracy of the three-dimensional position of the implants was measured, and at the 6 month return visit, the modified Plaque Index (mPLI), modified Sulcular Bleeding Index (mSBI) and probing depth (PD) were measured. Results : In the control group and experimental group, the vertical errors at the top of the implants were 1.246 ± 0.072 mm and 0.628 ± 0.046 mm (t = 26.078, P < 0.001), respectively, and the horizontal errors were 1.563 ± 0.086 mm and 0.546 ± 0.056 mm (t = 35.813, P < 0.001), respectively; and the vertical errors at the root of the implants were 1.352 ± 0.042 mm and 0.532 ± 0.030 mm (t = 57.021, P < 0.001), respectively, and the horizontal errors were 1.645 ± 0.076 mm and 0.625 ± 0.072 mm (t = 35.086, P < 0.001), respectively. For the experimental group, the mPLI value was 0.923 ± 0.760, the mSBI value was 0.846 ± 0.689, and the PD value was 3.460 ± 0.713 mm, which were significantly lower than those of the control group. For the control group, the mPLI value was 1.769 ± 0.927 (t = 2.546, P = 0.018), the mSBI value was 1.692 ± 0.947 (t = 22.605, P = 0.016) and the PD value was (4.579 ± 0.475) mm (t = 4.709, P < 0.001). Conclusion A digital surgical guide plate can increase the precision of immediate implantation and the peri-implant health in the molar area.

Objective To investigate the epidemiology characteristics of crawfish related rhabdomyolysis (RM) in Nanjing, 2016.Methods Outpatient and inpatient electronic medical system of 21 hospitals in Nanjing during 2016 were retrospectively searched, and all the patients diagnosed with RM were selected. The patients with none crayfish-related RM was excluded. The epidemiology characteristics were depicted. The geographic information system (GIS) was used to collect, manage and analyze the spatial data, to visualize it, to analyze the spatial distribution features of the disease, and to explore the cause of disease prediction. GeoDa 1.8 software was used to analyze the global and local spatial auto-correlation.Results A total of 1183 patients with crawfish related RM were initially screened, excluding 59 patients with RM caused by trauma, severe exercise, heat stroke, myositis, poisoning, drugs, and genetic diseases, and 1124 patients were enrolled. The proportion of men was 36.48% (410/1124) with an incidence of 12.54/100 thousands; while of women was 63.52% (714/1124) with an incidence of 21.86/100 thousands. The median age at onset was 34 (28, 43) years. From July to August, the incidence of crawfish related RM was the highest, accounting for 96.53% of the total number of cases. The top four incidence areas were Pukou (41.54/100 thousands), Jianye (25.94/100 thousands), Qixia (25.73/100 thousands), Gulou (25.04/100 thousands), all of which were adjacent to the Yangtze River. Global spatial autocorrelation analysis showed: MoranI = 0.427,Z = 2.646,P = 0.003, suggesting that the crawfish related RM had positive spatial autocorrelation. The results showed that the spatial structure of crawfish related RM existed in Nanjing in 2016. Local spatial autocorrelation analysis showed that the high-high concentration areas were Pukou, Jianye and Liuhe. The incidences of above three areas which were the Nanjing section of the lower reaches of the Yangtze River flowed through the region and surrounding areas were higher than the overall incidence of Nanjing.Conclusion The prevalence of crawfish related RM in Nanjing during 2016 had an obvious region-concentrated character and global spatial autocorrelation with the high prevalent regions mainly concentrated in the urban areas adjacent to the Yangtze River.

Objective To investigate the expressions of myostatin (MSTN) in the gastric cancer patients' rectus abdominis and serum,and to discuss its relation with the nutritional status and outcome of the gastric cancer patients.Methods We recruited 102 patients with gastric cancer and another 53 patients with benign abdominal disease who were admitted to Zhejiang Province People's Hospital and Tongde Hospital of Zhejiang Province from February 2008 to February 2011.We tested MSTN expression in the malignant patients' rectus abdominis and serum using reverse transcription polymerase chain reaction,Western blot,and enzymelinked immunosorbent assay.Relationship between MSTN expression and nutrition status of gastric cancer patients was explored.Results The relative expression of MSTN mRNA of rectus abdominis muscle in gastric cancer group and control group was 3.43 ± 1.11 and 1.07 ± 0.31 (t =19.406,P ＜ 0.01),the relative expression level of MSTN protein in gastric cancer group and control group was 0.115±0.696 and 0.085±0.499 (t=2.856,P＜0.05) and its serum expression 8.79±4.32 and 1.21±0.55 in these two group (t =16.701,P＜0.05),showing significant difference.The high (defined as higher than median) expression of MSTN in rectus abdominis muscle of gastric cancer patients was significantly correlated with age (x2 =22.039,P =0.000),percentage of more than 10％ decline in body weight in half a year (x2 =14.365,P=0.000),body mass index (BMI) ＜22 kg/m2 (x2 =6.800,P=0.009),serum albumin (x2 =31.018,P=0.000),hemoglobin (x2=10.079,P =0.001),prognostic nutritional index (x2 =10.074,P =0.002),higher Nutritional Risk Screening 2002 Score (Z=2.628,P=-0.009),tumor stage of TNM (Z=2.550,P=0.011).The expression of the rectus abdominis muscle in patients with gastric cancer was significantly correlated with the survival rate of the patients (x2 =12.200,P＜0.01).Conclusions The expression of MSTN increases in the rectus abdominis and serum of gastric cancer patients with cachexia.The increased MSTN expression is closely related with malnutrition and TNM stage in these patients,suggesting MSTN may also play an important role in the muscle consumption of the gastric cancer patients.
