ABSTRACT
Objective:To explore the clinical characteristics of patients with colchicine poisoning, and analyze the risk factors affecting the prognosis of colchicine poisoning and its value in the prognostic assessment.Methods:Patients with colchicine poisoning admitted to the Emergency Intensive Care Unit of the First Affiliated Hospital of Wenzhou Medical University from December 2017 to October 2022 were retrospectively included and divided into the survival group and death group according to the 14-d outcome. The general conditions of the two groups of patients were compared, and the clinical characteristics of patients with colchicine poisoning were analyzed. The differences of laboratory indexes, electrocardiogram, cardiac ultrasound and other clinical indexes during the first admission of patients between the two groups were compared, and their value in the prognosis evaluation of patients with colchicine poisoning was explored.Results:There were 41 patients with colchicine poisoning, aged 15-85 years, including 35 males and 6 females. There were 27 patients (65.9%) in the survival group and 14 patients (34.1%) in the death group, including accumulative poisoning (58.7%) and suicide poisoning (41.3%). The main clinical manifestations of patients with colchicine poisoning were gastrointestinal symptoms (82.93%), multiple organ dysfunction (78.05%), infectious fever (73.17%), myocardial damage (48.78%), coagulation dysfunction (46.34%), and bone marrow suppression (41.46%). Intestinal obstruction (19.51%) and rhabdomyolysis (2.44%) occurred in some patients. Multivariate Logistic regression analysis showed that the increase in absolute value of QTc interval ( OR=1.028, 95% CI: 1.000~1.056, P<0.05), lactic acid ( OR=1.599, 95% CI: 1.088~2.350, P<0.05), prothrombin time ( OR=1.205, 95% CI: 1.002~1.450, P<0.05), D-dimer ( OR=1.242, 95% CI: 1.089~1.417, P<0.05), and alkaline phosphatase ( OR=1.013, 95% CI: 1.002~1.024, P<0.05) were the risk factors for the prognosis of patients with colchicine poisoning. The decrease in the absolute value of ADL score ( OR=0.947, 95% CI: 0.909~0.988, P<0.05) and indirect bilirubin ( OR=0.756, 95% CI: 0.572~0.999, P<0.05) were the protective factors for the prognosis of patients with colchicine poisoning. D-dimer (AUC=0.913), lactic acid (AUC= 0.875) and alkaline phosphatase (AUC=0.770) had predictive value for the prognosis of patients with colchicine poisoning, and their cut-off values were 8.965 mg/L, 4.05 mmol/L and 230.5 U/L, respectively. Conclusions:The patients with colchicine poisoning have multiple organ dysfunction on admission, and are in a critical condition. The early levels of D-dimer, lactic acid and alkaline phosphatase could effectively predict the prognosis of patients with colchicine poisoning.
ABSTRACT
Objective:To explore the clinical characteristics of patients with paraquat mixed with diquat poisoning.Methods:The clinical data of 145 patients with paraquat mixed with diquat poisoning admitted to the Department of Emergency of the First Affiliated Hospital of Wenzhou Medical University from January 20, 2016 to March 31, 2022 were retrospectively analyzed. According to the detection results of plasma toxicants in patients with poisoning, the patients were divided into the paraquat diquat mixed group (mixed group), paraquat group (PQ group) and diquat group (DQ group). The clinical indexes, organ dysfunction, different poisoning doses and prognosis of the three groups were compared. Patients in the mixed group were divided into the survival group and death group according to their 90-day survival, and the differences of each index between the two groups were compared. Kaplan-Meier survival analysis was conducted for each index. After Log-rank test, multivariate Cox regression was used to analyze the risk factors of death in the mixed group.Results:A total of 31 patients were included in the mixed group, 92 patients in the PQ group, and 22 patients in the DQ group. There were significant differences in age, toxic dose, number of organ dysfunction, PSS score and APACHE II score among the three groups ( P<0.05). The main injured organs of the mixed group were gastrointestinal tract, kidney, liver, lung and nervous system. The proportion of organ damage in the mixed group was higher than that in the PQ group and DQ group. The white blood cell count, neutrophil count, HB, creatinine, AST, lactic acid, PT and APTT were statistically significant among the three groups ( P<0.05). In the mixed group, patients taking oral administration of < 20 mL all survived; 8 patients taking oral administration of 20 -50 mL died; 11 patients took oral administration of 51-100 mL and 8 (72.7%) died; and 10 patients took oral administration of more than 100 mL and 9 patients (90%) died. In the mixed group, patients with the concentration of diquat > 5000 ng/mL died. Among 31 patients with mixed poisoning, 30 patients (96.78%) had significantly higher concentrations of diquat than paraquat. There were no significant differences in sex, age, time from poisoning to hospitalization, ingestion amount, lymphocyte count, Hb, BNU, CK, total bilirubin, PH, and PT between the survival group and the death group ( P>0.05). Multivariate Cox regression analysis showed that the ingestion amount, plasma PQ concentration at admission, plasma DQ concentration at admission, and lactic acid were independent risk factors for death ( P<0.05). Conclusions:Paraquat mixed with diquat can cause multiple organ function damage. The main damaged organs are gastrointestinal tract, kidney, liver, lung and nervous system. Compared with PQ or DQ poisoning, mixed poisoning has a higher incidence of organ damage, a more serious condition, and a higher mortality rate. Ingestion amount, plasma PQ concentration at admission, plasma DQ concentration at admission and lactic acid were independent factors influencing the prognosis of mixed poisoning.
ABSTRACT
Objective:To explore the relationship between hematocrit, early fluid therapy, and clinical outcomes in patients with septic shock, and to provide evidence for fluid resuscitation therapy and prognosis assessment in these patients.Methods:The clinical information of patients with septic shock who were diagnosed and treated in the Emergency Intensive Care Unit (EICU) of the First Affiliated Hospital of Wenzhou Medical University from January 1, 2018 to December 31, 2020 were collected. Taking the survival or death of patients 28 days after admission as the end point of clinical research, the patients were divided into the survival and death groups. After analyzing the basic data of the two groups, the univariate and multivariate COX regression analyses were used to analyze the evaluation value of Δ Hematocrit (HCT) d2-d1 and ΔHCT d3-d1 on the prognosis of patients with septic shock. At the same time, the Kaplan-Meier survival curve was used to analyze the overall survival rate of patients with septic shock, and the smooth curve fitting graph was used to verify its relationship with net fluid intake and death. Results:There were 241 cases in the survival group and 67 cases in the death group. Univariate COX analysis showed statistically significant differences between the survival and death groups in acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) ( P=0.0006), red cell volume distribution width (RDW) ( P=0.0043), age ( P=0.0184), ΔHCT d2-d1 ( P=0.0136), ΔHCT d3-d1 ( P=0.0204), and white blood cell (WBC) ( P=0.0444). Multivariate COX analysis showed that ΔHCT d2-d1 ( P=0.0115) and ΔHCT d3-d1 ( P=0.0029) were independent risk factors for death in EICU patients with septic shock. ΔHCT d2-d1 and ΔHCT d3-d1 were divided into three groups according to the three-digit method. The Kaplan-Meier survival curve showed no significant difference among the three groups in the overall survival rate related to ΔHCT d2-d1 ( P=0.16), but there was a statistically significant difference in the overall survival rate among the three groups related to ΔHCT d3-d1 ( P=0.025). The smooth fitting curve of ΔHCT d3-d1, net fluid intake, and prognosis showed that ΔHCT d3-d1 was negatively correlated with net fluid intake, and the middle ΔHCT d3-d1 group had the best prognosis. Conclusions:The value of ΔHCT d3-d1 is related to the net fluid intake of patients with septic shock. An appropriate decrease in HCT on the third day can improve the prognosis of patients with septic shock. The dynamic changes of hematocrit can provide a certain basis for fluid resuscitation and prognosis evaluation in patients with septic shock.
ABSTRACT
Objective:To explore the predictive value of the serum C-reactive protein (CRP)/albumin (ALB) ratio (CAR) for organ damage in tsutsugamushi disease.Methods:The clinical data of 166 patients with tsutsugamushi disease admitted to the First Affiliated Hospital of Wenzhou Medical University from January 1, 2010 to December 31, 2020 were retrospectively analyzed. The patients were divided into the organ damage group (72 cases) and non-organ damage group (94 cases) according to the organ damage criteria. The general data and laboratory test results of the two groups of patients were compared. The significant indicators of univariate analysis were analyzed by multivariate logistic regression analysis. The receiver operating characteristic (ROC) curve and area under the curve (AUC) were used to analyze the predictive value of CAR for organ damage in patients with tsutsugamushi disease.Results:There were no significant differences in age, sex, days of fever, and admission body temperature between the organ damage group and non-organ damage group ( P>0.05). However, the body mass index, acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ), sequential organ failure assessment (SOFA), length of hospital stay, hospitalization expense, percentage of neutrophils (NEUT), lymphocyte count, procalcitonin, CRP, and CAR in the organ damage group were significantly higher than those in the non-organ damage group ( P<0.05), and ALB was significantly lower than that in the non-organ damage group ( P<0.05). Multivariate logistic regression analysis showed that APACHEⅡ( P=0.039), NEUT ( P=0.003), and CAR ( P=0.011) were independent risk factors for tsutsugamushi disease complicated by organ damage. The ROC curve showed that the AUCs of APACHEⅡ, NEUT, and CAR were 0.655, 0.716, and 0.727, respectively. When the cut-off value of CAR was 2.86, the sensitivity was 55.6%, and the specificity was 79.8%. Conclusions:Elevated CAR is an independent risk factor for tsutsugamushi disease complicated with organ damage and can be used as an important indicator to evaluate the presence or absence of organ damage in patients with tsutsugamushi disease.

ABSTRACT
Postpartum depression(PPD)is one of the most common types of postpartum psychiatric syndromes. Because of the complex and changeable characteristics in PPD disease and the special period after childbirth, there are many clinical limitations in the study of this disease. Therefore,the preparation and establishment of a proper animal model closed to clinical and behavioral evaluation method plays an important role in study of its pathogenesis. This review mainly introduces the commonly used postpartum depression animal models and the behavioral evaluation method. It is hoped to provide a reference for further study of PPD pathogenesis and for the drug research and development.

ABSTRACT
BACKGROUND:In closed fractures, the initial hematoma that is inclined to remove is seldom considered as the important reasons for bone healing. OBJECTIVE:To observe the mechanism and potential role of original fracture hematoma in fracture healing. METHODS:Ninety-six patients with closed fractures of the long bones undergoing open reduction and internal fixation were randomly divided into experimental group (n=48) and control group (n=48). In the experimental group, original fracture hematoma, 1.0-2.0 mL, was first taken out during the internal fixation and placed into a special sterile plastic bag; then, 3-4 pieces of hematomas were filed into the fracture site and sutured layer by layer. On the contrary, original fracture hematomas from the control group were discarded. Blood samples were extracted to detect the biochemical indicators at 1 month after internal fixation. X-ray examination was done at 1, 3, 6 months after internal fixation for observation of fracture healing. RESULTS AND CONCLUSION: X-ray films showed that the healing rate at 3 months after operation was 95% in the experimental group and 78% in the control group, and there was a significant difference between the two groups (P < 0.05). Levels of bone glaprotein, I-type precolagen carboxy terminus peptide and serum bone alkaline phosphatase were significantly higher in the experimental group than the control group (P < 0.01 orP < 0.05). These findings indicate that the original fracture hematoma can accelerate calus formation, promote bone induction, provide nutrition to the fracture site, and participate in revascularization. Therefore, the original fracture hematomas is one of the effectively therapeutic methods for union and nonunion of fractures.
