ABSTRACT

Objective: To examine the clinical value of fluorescence-guided indocyanine green (ICG) laparoscopic anatomical hepatectomy in the treatment of primary hepatocellular carcinoma. Methods: Data from patients diagnosed with hepatocellular carcinoma and who underwent laparoscopic hepatectomy with ICG fluorescence navigation in the Department of Liver Surgery and Liver Transplantation Center of West China Hospital between September 2020 and May 2022 were retrospectively collected. There were 53 males and 19 females, with an age of (55.5±12.9)years(range:42.6 to 68.4 years). Among them, 13 of the cases underwent laparoscopic anatomical liver resection(LALR) guided by tans-arterial ICG,43 of the cases received LAIR guided by portal vein negative ICG, and 16 of the cases received LALR positive by portal vein. Comparison among the three groups was performed by one-way ANOVA; and the rank sum test was used for comparison between groups. The counting data was expressed as percentage,and the χ2 test or Fisher's exact probability method was used for comparison between groups. Results: (1) Postoperative pathology: Resection R0 was achieved in all operations. The maximum tumor diameter of the patients in the arterial staining group, the reverse staining group, and the positive staining group(M (IQR)) was 2.5 (2.4) cm, 3.0 (2.5) cm and 3.0(2.4) cm,respectively. There were no statistically significant differences in the maximum tumor diameter between the three groups (P=0.364). The minimum tumor margin was 1.1 (1.1) cm, 1.0 (1.0) cm, 1.1 (1.6) cm in the the arterial staining group, reverse staining group and the positive staining group, respectively. There was no significant difference in the margin among the three groups (P=0.878). (2) Operation conditions: the operation time of the arterial staining group, the negative staining group, and the positive portal staining group was (348±93)minutes,(277±112)minutes,and (295±116)minutes,respectively. There were no significant differences in operation time among the three groups (P=0.134). The intraoperative blood loss of the three groups was 80(150)ml,200(350)ml,and 100(150)ml,respectively. There was no statistically significant difference in intraoperative bleeding volume between the three groups(P=0.743). All cases were not transfused during the operation and were not converted to laparotomy. ALT in the arterial staining group was higher than in the negative staining group in the first two days after the operation ((559±398)IU/L307(257) IU/L, q=235.5,P=0.004;(611±389)IU/L(331±242) IU/L, q=265.2, P=0.002). There was only one case of a grade III complication (Clavien-Dindo grading system) postoperative complication in the negative and positive staining group of the portal vein, respectively. Tumor markers in all patients decreased to the normal range after 2 months of operation. Conclusion: Laparoscopic anatomical hepatectomy guided by ICG fluorescence through arterial staining and portal vein staining is safe and feasible for primary hepatocellular carcinoma treatment.

ABSTRACT

Objective To investigate the effects of formononetin (FMN) on cognitive behavior and inflammation in aging rats with chronic unpredictable mild stress (CUMS). Methods SD rats aged about 70 weeks were divided into healthy control group, CUMS model group, CUMS combined with 10 mg/kg FMN group, CUMS combined with 20 mg/kg FMN group and CUMS combined with 1.8 mg/kg fluoxetine hydrochloride (Flu) group. Except for healthy control group, other groups were stimulated with CUMS and administered drugs for 28 days. Sugar water preference, forced swimming experiment and open field experiment were used to observe the emotional behavior of rats in each group. HE staining was used to observe the pathological injury degree of brain equine area. The contents of 5-hydroxytryptamine (5-HT) and 5-hydroxyindoleacetic acid (5-HIAA) were detected by the kit. The apoptosis was tested by terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL) in the brain tissue. The levels of tumor necrosis factor α (TNF-α), inducible nitric oxide synthase (iNOS) and interleukin 6 (IL-6) in peripheral blood were measured by ELISA. Western blot analysis was used to detect Bcl2, Bcl2 associated X protein (BAX), cleaved caspase-9, cleaved caspase-3, Toll-like receptor 4 (TLR4), myeloid differentiation factor 88 (MyD88), and phosphorylated nuclear factor κB p65 (p-NF-κB p65) in brain tissues. Results Compared with CUMS model group, sugar water consumption, open field activity time, open field travel distance and swimming activity time significantly increased in the CUMS combined with 20 mg/kg FMN group and the CUMS combined with 1.8 mg/kg Flu group. The number of new outarm entry increased significantly, while the number of initial arm entry and other arm entry decreased significantly. The pathological damage of brain equine area was alleviated, and the contents of 5-HT and 5-HIAA were significantly increased. The ratio of BAX/Bcl2 and the expression of cleaved caspase-9 and cleaved caspase-3 protein as well as the number of apoptotic cells were significantly decreased. The contents of TNF-α, iNOS and IL-6 were significantly decreased. The protein levels of TLR4, MyD88 and p-NF-κB p65 were significantly decreased. Conclusion FMN can inhibit the release of inflammatory factors by blocking NF-κB pathway and improve cognitive and behavioral ability of CUMS aged rats.

ABSTRACT

Objective To analyze the death-related factors of elderly patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) treated by sequential mechanical ventilation,so as to provide evidence for clinical practice. Methods The clinical data of 1204 elderly patients (≥60 years old) with AECOPD treated by sequential mechanical ventilation from June 2015 to June 2021 were retrospectively analyzed.The probability and influencing factors of death were analyzed. Results Among the 1204 elderly patients with AECOPD treated by sequential mechanical ventilation,167 (13.87%) died.Multivariate analysis showed that plasma procalcitonin ≥0.5 μg/L (OR=2.762, 95%CI=1.920-3.972, P<0.001),daily invasive ventilation time ≥12 h (OR=2.202, 95%CI=1.487-3.262,P<0.001),multi-drug resistant bacterial infection (OR=1.790,95%CI=1.237-2.591,P=0.002),oxygenation index<39.90 kPa (OR=2.447,95%CI=1.625-3.685,P<0.001),glycosylated hemoglobin >6% (OR=2.288,95%CI=1.509-3.470,P<0.001),and acute physiology and chronic health evaluation Ⅱ score ≥25 points (OR=2.126,95%CI=1.432-3.156,P<0.001) were independent risk factors for death in patients with AECOPD treated by sequential mechanical ventilation.Oral care>twice/d (OR=0.676,95%CI=0.457-1.000,P=0.048) and sputum excretion>twice/d (OR=0.492, 95%CI=0.311-0.776, P=0.002) were independent protective factors for death in elderly patients with AECOPD treated by sequential mechanical ventilation. Conclusions The outcomes of sequential mechanical ventilation in the treatment of elderly patients with AECOPD are affected by a variety of factors.To reduce the mortality,we put forward the following measures:attaching great importance to severe patients,restoring oxygenation function,shortening unnecessary invasive ventilation time,controlling blood glucose,preventing multidrug resistant bacterial infection,oral care twice a day,and sputum excretion twice a day.

ABSTRACT

Objective:To analyze the relationship between blood electrolytes and the prognosis of patients with severe coronavirus disease 2019 (COVID-19) and to provide assistance for clinical decision-making.Methods:The clinical data of patients with severe COVID-19 admitted to intensive care unit (ICU) of the Wuhan Third Hospital by the Shanghai aid-Hubei medical team from January 21 to March 4, 2020 were collected. Excluding ineligible patients, 110 patients were finally enrolled. The patients' gender, age, temperature, heart rate, systolic and diastolic blood pressure, clinical symptoms at admission, time of symptom onset, duration of fever, and relevant indicators at admission to ICU (including blood potassium, chloride, sodium, calcium, phosphorus, and magnesium, etc.) and prognosis were analyzed. The patients were grouped by blood potassium or calcium levels or blood potassium/calcium ratio. The Kaplan-Meier survival curves were used to analyze the survival of patients in each group. The relationship between the potassium/calcium ratio and the prognosis was analyzed using restricted cubic spline plots. The relationship between each index in the different models and the prognosis was analyzed using Cox regression models.Results:Among 110 severe COVID-19 patients, 78 cases survived, and 32 cases died. Compared with the surviving group, patients in the death group had higher blood potassium levels [mmol/L: 4.25 (3.80, 4.65) vs. 3.90 (3.60, 4.20), P < 0.05] and lower blood calcium levels (mmol/L: 2.00±0.14 vs. 2.19±0.18, P < 0.05). The Kaplan-Meier survival curves showed that patients in the potassium > 4.2 mmol/L group had a worse prognosis than the potassium < 3.8 mmol/L group and the potassium 3.8-4.2 mmol/L group ( P = 0.011), patients in the calcium > 2.23 mmol/L group had a better prognosis than the calcium < 2.03 mmol/L group and the calcium 2.03-2.23 mmol/L group, and the lower calcium group had a worse prognosis ( P = 0.000 15). Cox regression analysis showed that the hazard ratio ( HR) of blood potassium and calcium were 2.08 and 0.01, respectively, in model 1 (single blood potassium or calcium) and in model 2 (model 1 plus age and gender), the HR of blood potassium and calcium were 1.98 and 0.01 respectively, which were significantly associated with patient prognosis (all P < 0.05). Patients in the group with the potassium/calcium ratio > 1.9 had higher blood potassium levels and a higher proportion of mechanical ventilation, lower calcium levels and lower proportion of survival, and longer time of ICU admission compared with the groups with the potassium/calcium ratio < 1.7 and 1.7-1.9. The Kaplan-Meier survival curves showed that the survival rate of the potassium/calcium ratio > 1.9 group was the lowest ( P < 0.000 1), and there was no statistically significant difference in survival between the potassium/calcium ratio < 1.7 group and the potassium/calcium ratio 1.7-1.9 group. A restricted cubic spline plot corrected for age and gender showed that patients in the potassium/calcium ratio > 1.8 group had HR values > 1. Cox regression analysis corrected for other indicators showed that the potassium/calcium ratio was still associated with patient prognosis ( HR = 4.85, P = 0.033). Conclusions:Blood potassium, calcium, and the potassium/calcium ratio at ICU admission are related to the prognosis of patients with severe COVID-19, and the potassium/calcium ratio is an independent risk factor for the death of patients. The higher the potassium/calcium ratio, the worse the prognosis of patients.

ABSTRACT

Objective:To evaluate the effect of thymosin alpha 1 on the prognosis of patients with coronavirus disease 2019 (COVID-19).Methods:A retrospective cohort study was performed to collect clinical data of 95 patients treated by Shanghai Aid Medical Team in Wuhan Third Hospital during January 31, 2020 and March 4, 2020, who were confirmed COVID-19. They were divided into two groups according to whether they were treated with thymosin alpha 1 after admission. The 28-day mortality (primary outcome), and 28-ventilator-free-day, lymphocyte count (LYM) level, C-reactive protein (CRP) level (secondary outcomes) were compared between two groups. Survival analysis was performed using the Kaplan-Meier curve. The effect of thymosin alpha 1 on 28-day survival was evaluated with Cox regression model.Results:Among the 95 patients, there were 31 cases in thymosin group and 64 cases in non-thymosin group; 29 patients died 28 days after admission, including 11 cases (35.5%) in thymosin group and 18 cases (28.1%) in non-thymosin group. Kaplan-Meier survival curve showed that thymosin alpha 1 could improve the 28-day survival of patients with COVID-19, but the univariate Cox model analysis showed that the difference was not statistically significant [hazard ratio ( HR) = 0.48, 95% confidence interval (95% CI) was 0.20-1.14, P = 0.098]; multivariate Cox model analysis showed that thymosin alpha 1 was the factor to improve the 28-day mortality ( HR = 0.15, 95% CI was 0.04-0.55, P = 0.004), old age ( HR = 1.10, 95% CI was 1.05-1.15, P < 0.001), accompanied by chronic renal dysfunction ( HR = 42.35, 95% CI was 2.77-648.64, P = 0.007), decrease of LYM at admission ( HR = 0.15, 95% CI was 0.04-0.60, P = 0.007) and the use of methylprednisolone ( HR = 4.59, 95% CI was 1.26-16.67, P = 0.021) were also risk factors for the increase of 28-day mortality. The use of immunoglobulin and antiviral drugs abidol and ganciclovir did not affect the 28-day mortality. After adjustment for age, gender, LYM and other factors, weighted multivariate Cox analysis model showed thymosin alpha 1 could significantly improve the 28-day survival of COVID-19 patients ( HR = 0.45, 95% CI was 0.25-0.84, P = 0.012). In terms of secondary outcomes, no statistical difference (all P > 0.05) was found between two groups in days without ventilator at 28 days after admission (days: 17.97±13.56 vs. 20.09±12.67) and the increase of LYM at 7 days after admission [×10 9/L: -0.07 (-0.23, 0.43) vs. 0.12 (-0.54, 0.41)]. But the decrease of CRP at 7 days after admission in thymosin alpha group was significantly greater than that in non-thymosin group [mg/L: 39.99 (8.44, 82.22) vs. 0.53 (-7.78, 22.93), P < 0.05]. Conclusion:Thymosin alpha 1 may improve 28-day mortality and inflammation state in COVID-19 patients.

ABSTRACT

Objective:To compare and analyze the clinical features of patients with severe coronavirus disease 2019 (sCOVID-19) and severe community acquired pneumonia (sCAP) who meet the diagnostic criteria for severe pneumonia of the Infectious Diseases Society of America/American Thoracic Society (IDSA/ATS).Methods:A retrospective comparative analysis of the clinical records of 116 patients with sCOVID-19 admitted to the department of critical care medicine of Wuhan Third Hospital from January 1, 2020 to March 31, 2020 and 135 patients with sCAP admitted to the department of critical care medicine of Shanghai First People's Hospital from January 1, 2010 to December 31, 2017 was conducted. The basic information, diagnosis and comorbidities, laboratory data, etiology and imaging results, treatment, prognosis and outcome of the patients were collected. The differences in clinical data between sCOVID-19 and sCAP patients were compared, and the risk factors of death were analyzed.Results:The 28-day mortality of sCOVID-19 and sCAP patients were 50.9% (59/116) and 37.0% (50/135), respectively. The proportion of arterial partial pressure of oxygen/fraction of inspired oxygen (PaO 2/FiO 2)≤250 mmHg (1 mmHg ≈ 0.133 kPa) in sCOVID-19 patients was significantly higher than that of sCAP [62.1% (72/116) vs. 34.8% (47/135), P < 0.01]. The possible reason was that the proportion of multiple lung lobe infiltration in sCOVID-19 was significantly higher than that caused by sCAP [94.0% (109/116) vs. 40.0% (54/135), P < 0.01], but the proportion of sCOVID-19 patients requiring mechanical ventilation was significantly lower than that of sCAP [45.7% (53/116) vs. 60.0% (81/135), P < 0.05]. Further analysis of clinical indicators related to patient death found that for sCOVID-19 patients PaO 2/FiO 2, white blood cell count (WBC), neutrophils (NEU), neutrophil percentage (NEU%), neutrophil/lymphocyte ratio (NLR), total bilirubin (TBil), blood urea nitrogen (BUN), albumin (ALB), Ca 2+, prothrombin time (PT), D-dimer, C-reactive protein (CRP) and other indicators were significantly different between the death group and the survival group, in addition, the proportion of receiving mechanical ventilation, gamma globulin, steroid hormones and fluid resuscitation in death group were higher than survival group. Logistic regression analysis showed that the need for mechanical ventilation, NLR > 10, TBil > 10 μmol/L, lactate dehydrogenase (LDH) > 250 U/L were risk factors for death at 28 days. For sCAP patients, there were significant differences in age, BUN, ALB, blood glucose (GLU), Ca 2+ and D-dimer between the death group and the survival group, but there was no significant difference in treatment. Logistic regression analysis showed that BUN > 7.14 mmol/L and ALB < 30 g/L were risk factors for 28-day death of sCAP patients. Conclusions:The sCOVID-19 patients in this cohort have worse oxygen condition and symptoms than sCAP patients, which may be due to the high proportion of lesions involving the lungs. The indicators of the difference between the death group and the survival group were similar in sCOVID-19 and sCAP patients. It is suggested that the two diseases have similar effects on renal function, nutritional status and coagulation function. But there were still differences in risk factors affecting survival. It may be that sCOVID-19 has a greater impact on lung oxygenation function, inflammatory cascade response, and liver function, while sCAP has a greater impact on renal function and nutritional status.

ABSTRACT

Objective:To explore the morphology of coronoid process fracture in terrible triad injury based on Adams classification.Methods:A retrospective cross-sectional study was used to analyze the three-dimensional CT data of 51 patients with terrible trind injury treated at First Affiliated Hospital of Fujian Medical University from January 2013 to August 2021, including 33 males and 18 females, aged 18-88 years [(44.7±12.0)years]. The model of ulna coronoid process fracture was established by three-dimensional CT reconstruction technology and was classified according to Adams coronoid process fracture classification. Type I was the coronoid process tip fracture, type II the coronoid process transverse fracture, type III the base fracture of the coronoid process, type IV anterior internal fracture the anteromedial oblique fracture of the coronoid process, and type IV anterior external fracture the anterolateral oblique fracture of the coronoid process. According to the characteristics of the coronoid fracture fragment, type IV anterior external fracture was divided into two subtypes: α subtype involving the coronoid tip and β subtype without involving the coronoid tip. Then, the proportion, height, surface area and volume of different types of coronoid fractures were measured. The proportion, height, surface area and volume of fracture fragments of two subtypes of type IV anterior external fracture were measured, as well as the area of ulnar trochlear joint, area of trochlear joint of ulnar fracture fragment, proportion of the area of trochlear joint affected by the ulnar fragment, area of proximal radioulnar joint, area of proximal radioulnar joint of ulnar fracture fragment and proportion of the area of proximal radioulnar joint affected by the ulnar fragment.Results:Among the patients with terrible triad injury, the ulnar coronoid process fracture was Adams type I in 17 patients (33%), type II in 4 (8%), type III in 4 (8%), type IV anterior internal fracture in 4 (8%) and type IV anterior external fracture in 22 (43%). The height of fracture fragment of type I, type II, type III, type IV anterior internal fracture and type IV anterior external fracture was (3.7±1.9)mm, (10.8±1.1)mm, (14.4±1.2)mm, (5.2±2.4)mm and (6.7±2.6)mm, respectively; the surface area was 63.7(21.4, 221.0)mm 2, 1 086.8(606.8, 1 434.2)mm 2, 1 658.8(1 335.6, 1 695.4)mm 2, 437.3(185.6, 437.3)mm 2 and 511.8(198.8, 646.5)mm 2, respectively; the volume was 46.3(21.4, 180.5)mm 3, 938.7(629.8, 1 011.3)mm 3, 1 797.4(1 520.2, 1 903.7)mm 3, 429.3(138.1, 992.4)mm 3 and 461.9(144.9, 707.1)mm 3, respectively. There were significant differences in the height, surface area and volume of coronoid process fracture with different Adams classification (all P<0.01). Among 22 patients with type IV anterior external fracture, 12 patients were with α subtype and 10 with β subtype. The fracture height of α and β subtypes was (8.6±2.6)mm and (5.0±2.4)mm, respectively; the surface area was 633.2 (530.3, 727.4)mm 2 and 181.4 (136.7, 450.3)mm 2, respectively; the volume was 692.8 (477.6, 778.0)mm 3 and 128.0 (74.2, 405.1)mm 3, respectively. The height, surface area and volume of fracture fragment were significantly different between the two subtypes (all P<0.01). The area of ulnar trochlear joint of α and β subtypes were 901.4(755.1, 1 060.6)mm 2 and 835.2(767.7,909.3)mm 2, respectively; the area of trochlear joint of α and β subtype fragment was 104.1(79.4, 139.9)mm 2 and 38.8(21.3, 58.1)mm 2, respectively; the proportion of the area of trochlear joint affected by α and β subtype fragment was 0.12(0.09, 0.15) and 0.05(0.03, 0.07), respectively. There was no significant difference between α and β subtypes in the area of trochlear joint of ulna ( P>0.05), but the area of trochlear joint of α subtype fragment and proportion of the area of trochlear joint affected by α subtype fragment were higher than those of β subtype fragment (all P<0.01). The area of proxima radioulnar joint of α and β subtypes was 147.9(111.7,164.2)mm 2 and 137.0(118.7,166.7)mm 2, respectively; the area of proximal radioulnar joint of α and β subtypes fragment was 17.7(13.4, 52.2)mm 2 and 6.1(2.6, 20.0)mm 2, respectively; the proportion of the area of proximal radioulnar joint affected by α and β subtypes fragment was 0.12(0.10, 0.35) and 0.05(0.03, 0.15), respectively. There were no significant differences between the two subtypes in proximal radioulnar joint damage (all P>0.05). Conclusions:Adams type IV fracture of the coronoid process of the ulna occupies a large proportion in terrible triad injury, and the type IV anterior external fracture is the main type containing two subtypes with differences in fragment size and shape. However, the injuries to the proximal radioulnar joint surface are similar for the two subtypes, so the injuries of type IV anterior external fracture with different sizes to the proximal radioulnar joint surface should not be neglected in clinical treatment.

ABSTRACT

Objective:To explore the lag effect and correlation between daily average temperature and the incidence of other infectious diarrhea in Hebei Province.Methods:The data of meteorological factors (including temperature and average daily temperature) and the daily incidence of other infectious diarrhea in Zhangjiakou City, Chengde City, Tangshan City, Qinhuangdao City, Baoding City, Langfang City, Cangzhou City, Shijiazhuang City, Hengshui City, Xingtai City, and Handan City in Hebei Province from 2017 to 2020 were collected. Eleven prefecture-level cities were divided into four regions, including east, north, middle and south regions. Distributed lag non-linear model was applied to examine the non-linear associations and the lag effect of daily mean temperature on daily incidence of other infectious diarrhea. Meanwhile, the cold and hot effects were used to estinuate the lag-response relationship on the incidence of other infectious diarrhea.Results:A total of 231 008 cases of other infectious diarrhea were reported in Hebei Province. The seasonal distribution was obvious, showing a bimodal distribution of large peaks in summer and small peaks in winter. An inverse S-shaped association between average daily temperature and cumulative risk ratio ( RR) of other infectious diarrhea was observed in Hebei Province. Both high temperature (higher than 27.50 ℃) and low temperature (less than 13.67 ℃) could increase the risk of other infectious diarrhea. When the temperature was lower than 13.00 ℃, the lag time and RR had a U-shaped association (lag four to seven days, 23 to 30 days). Meanwhile, when it was higher than 13.00 ℃, it had an inverted U-shaped association (lag 5 to 21 days). A comparison of four regions of Hebei Province showed that the lag time from south to north was extended from six days to 30 days at low temperature effects with temperature P5=-7.24 ℃. When the temperature getting hot ( P95=28.25 ℃), the risk occurred at lag 0 days, and the lag time gradually got short from north to south. Thus, the high temperature effect reached maximum quickly with a relative short duration. Conclusions:The inverse S-shaped non-linear association between daily average temperature and the incidence of other infectious diarrhea in Hebei Province is observed. Both low temperature and high temperature are associated with increased risk of other infectious diarrhea. But the impact of low temperature is more notable, which has a relative long duration.

ABSTRACT

Objective:To investigate the differences in microbiological examination results between alcohol abuse and no alcohol abuse in adult ICU patients and the association between alcohol abuse and these differences.Methods:The adult patients with microbiological examination results were selected from the MIMIC-Ⅲ database and divided into two groups according to whether they had alcohol abuse. The two groups were matched by propensity score, and the similarities and differences in microbiological examination results were evaluated between the two groups after matching. The measurement data of non normal distribution were expressed by M ( Q1, Q3). Wilcoxon rank sum test was used for the comparison of the two groups, and the comparison of counting data was used χ 2 test or Fisher exact probability method. Results:After matching, the alcohol abuse patients were more likely to use mechanical ventilation (47.06% (1 379/2 930) vs. 52.66% (1 543/2 930), χ 2=18.14, P<0.001), had a higher positive rate in sputum samples (44.30% (400/903) vs. 49.41% (501/1 014), χ 2=4.81, P=0.028) and had a lower positive rate in other samples (26.85% (653/2 432) vs. 21.67% (541/2 496), χ 2=17.69, P<0.001). In blood samples, the percentage of Gram-negative bacteria was lower in the alcohol abuse group (26.87% (126/469) vs. 17.25% (74/429), χ 2=11.42, P<0.001), while the percentage of Gram-positive bacteria was higher (78.46% (368/469) vs. 86.01% (369/429), χ 2=8.17, P=0.004). The percentage of patients with Pseudomonas aeruginosa (3.75% (110/2 930) vs. 2.08% (61/2 930), χ 2=13.88, P<0.001) and Enterococcus sp. (8.19% (240/2 930) vs. 6.45% (189/2 930), χ 2=6.29, P=0.012) was lower in the alcohol abuse group. However, there was a higher percentage of patients with methicillin-resistant Staphylococcus aureus (2.32% (68/2 930) vs. 3.28% (96/2 930), χ 2=4.57, P=0.032) and Haemophilus influenzae (1.30% (38/2 930) vs. 2.01% (59/2930), χ 2=4.19, P=0.041) in the alcohol abuse group. For Staphylococcus aureus (61.10% (322/527) and 52.66% (267/507), χ 2=7.16, P=0.007) and Enterococcus sp. (75.83% (160/211) and 63.64% (56/88), χ 2=4.02, P=0.045), the alcohol abuse group had a lower resistance to levofloxacin; for Escherichia coli, Pseudomonas aeruginosa and Klebsiella pneumoniae, the alcohol abuse group had a lower resistance to cephalosporins (all P<0.05). Conclusions:In adult ICU, alcohol abuse might increase the risks of using mechanical ventilation, and patients with alcohol abuse might be more prone to have respiratory tract infections. Alcohol abuse patients with blood infections were less likely to be infected with Gram-negative bacteria, but had a higher probability of Gram-positive bacteria infection. What is more, Alcohol abuse might increase the risks of infections with Haemophilus influenzae and methicillin-resistant Staphylococcus aureus. In alcohol abuse patients, the infection of Staphylococcus aureus, Enterococcus sp., Escherichia coli, Pseudomonas aeruginosa, and Klebsiella pneumoniae was less resistant to many antibiotics than that in no alcohol abuse patients.

ABSTRACT

Objective:In the process of fat grafting, there is no good solution to achieve delicate filling while retaining the viability of fat particle. There was still no research on the composition and activity of delicate fat particle. In this study, two different methods for delicate fat process were established to explore the feasibility and clinical efficacy.Methods:From December 2015 to June 2016, 5 patients (22-31 years old, with average 26.2 years) with abdominal liposuction in Shanghai Ninth People's Hospital were inclueded. The fat particles were obtained by floating method and filtration method respectively, and compared with emulsified fat/nanofat and traditional fat grafts. The cell viability and composition of adipose tissue were compared in each group through cell viability test, flow analysis and tissue staining.Results:The fat particles obtained by floating and filtration methods, emulsified fat could pass through OT needle. Cell viability test revealed the presence of living cells in the fat obtained by both methods, but not in the emulsified fat. Flow analysis showed that the expression of CD90 in floating group was higher than that in control group ( P=0.048). Conclusions:The delicate fat particle can be obtained by floating or filtration method, which can preserves the tissue integrity and cell viability; meanwhile it can achieve fine needle injection and clinical application.

ABSTRACT

Objective:To provide normal reference thresholds for clinical dynamic monitoring of the risk of microthrombus during pregnancy, we aimed to establish reference intervals of D-dimer in healthy pregnant women during different periods of gestation in Xi′an.Method:From December 2020 to March 2022, a total of 1502 healthy pregnant women and healthy non-pregnant women (healthy non-pregnant control group) who received routine prenatal examination in Northwest Women and Children′s Hospital were recruited in the study by questionnaire, including 1236 healthy pregnant women and 266 healthy non-pregnant control group. Plasma D-dimer concentration was detected by STA-R Evolution automatic blood coagulation analyzer and the concentration levels of D-dimer in different pregnancies and age groups were calculated using Graph Prism 9.0 software. In addition, 20 samples were collected in each pregnancy to verify the established reference interval.Results:There was no significant difference in plasma D-dimer levels between<30 years old and ≥30 years old at different gestational weeks. Plasma D-dimer level in healthy pregnant women group was significantly higher than that in healthy non-pregnant women group of the same age (P<0.05). With the increase of gestational week, plasma D-dimer level in pregnant women increased significantly, and plasma D-dimer level at different gestational weeks ≤13 weeks, 13+ 1-20 weeks, 20+ 1-27 weeks, 27+ 1-35 weeks, ≥35 +1 week were 0.33 (0.26, 0.47) μg/ml, 0.41 (0.30, 0.51) μg/ml, 0.71 (0.48, 0.94) μg/ml, 0.91 (0.70, 1.27) μg/ml, 1.30 (0.96, 1.72) μg/mlrespectively. Unilateral reference interval acuities were≤0.89 μg/ml, ≤1.53 μg/ml, ≤2.44 μg/ml, ≤2.74 μg/ml, ≤3.82 μg/ml respectively. The reference range established in this study was verified by 20 independent samples from each of the 5 gestational age groups, and the results were acceptable. Conclusion:This study preliminarily established the reference interval of plasma D-dimer in healthy pregnant women at different gestational weeks in Xi ′an area, which is helpful for the auxiliary diagnosis of thrombotic diseases during pregnancy.

ABSTRACT

Objective:To establish the biology reference interval (RI) of peripheral blood procalcitonin (PCT) for children between 3 days and 6 years old in China.Methods:Totally 3 353 reference individuals with apparent health or no specific diseases were recruited in 18 hospitals throughout the country during October 2020 to May 2021. Reference individuals were divided into four groups: 3-28 days, 29 days - 1 year, 1-3 years and 4-6 years. Vein blood or capillary blood were collected by percutaneous puncture from every reference individual. The PCT level in serum and the capillary whole blood were assayed by Roche Cobas e601 and Norman NRM411-S7 immunoanalyzer. Outliers were deleted and 95th percentiles of every group were provided as RIs. Man-Whitney U test or Kruskal-Wallis test were used performed to assess the difference among different gender, age or method groups. Results:The difference of PCT distribution between male and female is not statistically significant, but the difference between serum and capillary whole blood is statistically significant. The differences between age groups are significant too. For Roche e601, serum PCT RI of 3-28 days group is <0.23 μg/L, 29 days - 6 years are <0.11 μg/L. For NRM411, Serum PCT RI of 3-28 days group is <0.21 μg/L, 29 days - 1 year: <0.09 μg/L, 1 - 6 years: <0.10 μg/L. For whole blood PCT, RI of 3-28 days group is <0.26 μg/L, 29 days - 6 years is <0.15 μg/L.Conclusions:Serum and capillary whole blood PCT have different RIs, however, capillary whole blood PCT testing is valuable in pediatric application. Children in 3-28 days show higher PCT levels than other age group. To establish the RIs and understand the differences among different groups are essential for the interpretation and clinical application of peripheral blood PCT testing results.

ABSTRACT

Objective To explore the clinical characteristics and treatment of Pseudomonas peritoneal dialysis-associated peritonitis(PsP). Methods The data of patients receiving peritoneal dialysis in four tertiary hospitals in Jilin province from 2015 to 2019 were retrospectively analyzed.According to the etiological classification,the patients with peritoneal dialysis-associated peritonitis(PDAP)were classified into PsP group and non-PsP group.The incidence of PsP was calculated,and the clinical characteristics and treatment outcomes of the two groups were compared.Kaplan-Meier method was used to draw the survival curve,and Cox regression was performed to analyze the risk factors affecting the technical failure of PsP.The treatment options of Pseudomonas aeruginosa-caused PDAP and the drug sensitivity of PsP were summarized. Results A total of 1530 peritoneal dialysis patients with complete data were included in this study,among which 439 patients had 664 times of PDAP.The incidence of PsP was 0.007 episodes/patient-year.PsP group had higher proportion of refractory peritonitis(41.38% vs.19.69%,P=0.005),lower cure rate(55.17% vs.80.79%, P=0.001),and higher extubation rate(24.14% vs.7.09%,P=0.003)than non-PsP group.The technical survival rate of PsP group was lower than that of non-PsP group(P<0.001).Multivariate Cox regression analysis showed that Pseudomonas aeruginosa was an independent risk factor for technical failure in patients with PsP(HR=9.020,95%CI=1.141-71.279,P=0.037).Pseudomonas was highly sensitive to amikacin,meropenem,and piperacillin-tazobactam while highly resistant to compound sulfamethoxazole,cefazolin,and ampicillin. Conclusion The treatment outcome of PsP is worse than that of non-PsP,and Pseudomonas aeruginosa is an independent risk factor for technical failure of PsP.

ABSTRACT

Cultivating salt-alkali tolerant rice varieties is one of the important ways to meet the increasing food demand of growing global population. In this study, twenty-one rice germplasms with different salt-alkali tolerance were treated with six salt-alkali concentrations at germination and seedling stages. The germination potential, germination rate, shoot length, root length, root number, fresh weight of shoot and seedlings were measured. The average value of salt damage rate was used to evaluate the salt-alkali tolerance. As the salt-alkali concentration increases, the inhibition on seed germination and growth became more obvious. Upon treatment with 1% NaCl plus 0.25% NaHCO3, the salt damage rate of germination rate has the largest variation, ranging from 0% to 89.80%. The salt damage rate of each trait shows a similar trend at all concentrations. Four germplasm resources with strong salt-alkali tolerance (Dajiugu, Nippobare, Mowanggu and 02428) and 7 sensitive germplasms were screened. The salt-tolerant gene sequence of 4 salt-alkali tolerant varieties and 3 sensitive germplasms were analyzed. OSHAL3 and OsRR22 were identical among the 7 germplasms, but SKC1 and DST showed clear variations between the salt-alkali tolerant and sensitive germplasms. Besides the salt-alkali tolerant germplasm resources, this study can also serve as a reference for mining of genes involved in salt-alkali tolerance and breeding of salt-alkali tolerant rice varieties.

ABSTRACT

Objective To verify the relationship between catheter-related urinary tract infection(CAUTI)and stress hyperglycemia during catheter retention in stroke patients. Methods We used nosocomial infection monitoring system to track the status of CAUTI in stroke patients in a hospital.The study cohort was all the patients who received retention catheterization from January 2016 to March 2020.According to the nested case-control design,multivariate logistic regression analysis was performed to explore the relationship between stress hyperglycemia and CAUTI in stroke patients with indwelling catheter. Results A total of 322 cases of CAUTI and 644 cases of non-CAUTI were enrolled in this study.The length of stay in the case group was(20.68 ± 3.73)d,significantly longer than that[(13.00 ± 4.01)d]in the control group(t=29.473,P <0.001).Compared with non-stress hyperglycemia,stress hyperglycemia posed a higher risk of CAUTI in the stroke patients with indwelling catheter(OR=2.020,95% CI=1.447-2.821,P=0.000)and led to the higher incidence of CAUTI in one thousand days(P<0.001). Conclusion Stress hyperglycemia in the stroke patients with indwelling catheter can significantly increase the risk of CAUTI.

ABSTRACT

Objective:To analyze the types of ulnar coronoid process fractures in terrible triad injury (TTI) using three coronoid fracture classification systems and to explore the characteristics of coronoid process fractures and compare the reliability of different coronoid process fractures classification systems in TTI.Methods:A retrospective case series study was used to analyze the CT data of 43 patients with typical TTI admitted to First Affiliated Hospital of Fujian Medical University from January 2013 to October 2020. There were 26 males and 17 females, aged from 18 to 88 years [(41.8±15.6)years]. An independent three-dimensional model of the proximal ulna was established using the CT three-dimensional reconstruction technology. The characteristics of the coronoid process fractures were observed. The Regan-Morrey classification, O'Driscoll classification and Adams classification were used to classify the ulnar coronoid process fractures. The reliability of the three classification systems of coronoid fractures was analyzed.Results:The fracture line of the coronoid process was mostly located anterolaterally. Among all patients with ulnar coronoid fractures, there were 17 patients (40%) with type I, 19 (44%) with type II and 7(16%) with type III according to Regan-Morrey classification; there were 34 patients (79%) with type I, 2(5%) with type II and 7(16%) with type III according to O'Driscoll classification; there were 12 patients (28%) with type I, 3(7%) with type II, 7(16%) with type III, 18(42%) with type IV AL and 2(5%) with type IV AM according to Adams classification. Through reliability analysis, the Kappa coefficients of the inter-observer and intra-observer 1, 2, 3 of Regan-Morrey classification were 0.752, 0.813, 0.772 and 0.703, respectively; the Kappa coefficients of the inter-observer and intra-observer 1, 2, 3 of O'Driscoll classification were 0.797, 0.774, 0.837 and 0.775, respectively; the Kappa coefficients of the inter-observer and intra-observer 1, 2, 3 of Adams classification were 0.805, 0.835, 0.837 and 0.875, respectively.Conclusions:Most of the coronoid process fractures locate anterolaterally in TTI. Compared with Regan-Morrey classification and O'Driscoll classification, the reliability of Adams classification is best. Adams classification further subdivides the anterolateral fractures of the coronoid process, which may be more suitable in evaluating the classification of ulnar coronoid process fractures in TTI.

ABSTRACT

Objective:To investigate the clinical effect of Jiedu Limai decoction in septic patients with syndrome of heat-toxin exuberance.Methods:A prospective randomized controlled trial was conducted. From March 2019 to April 2020, septic patients with syndrome of heat-toxin exuberance admitted to intensive care unit (ICU) of Shanghai General Hospital and Songjiang Branch of Shanghai General Hospital were enrolled as the research objects, and they were divided into routine treatment group and Jiedu Limai decoction group by the random number table method. Patients in both groups were given standard treatment in accordance with the guidelines, and patients in the Jiedu Limai decoction group were given Jiedu Limai decoction in addition to the standard treatment, once a day for 14 days. The 28-day survival of patients of the two groups were recorded, the acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) score, sequential organ failure assessment (SOFA) score, coagulation indexes, infection indexes, inflammatory cytokines and organ function indicators before treatment and 7 days after treatment in both groups were recorded, and the prognosis of the two groups were recorded.Results:A total of 259 patients with infection or clinical diagnosis of infection admitted during the experimental observation period were included, and those who did not meet the Sepsis-3 diagnostic criteria, more than 80 years old or less than 18 years old, with multiple tumor metastases, autoimmune system diseases, with length of ICU stay less than 24 hours, with acute active gastrointestinal bleeding and with incomplete data were excluded. One hundred patients were finally enrolled, with 50 patients in the routine treatment group and 50 patients in the Jiedu Limai decoction group. There were no statistically significant differences in coagulation indexes, infection indicators, inflammatory cytokines and organ function indicators before treatment between the two groups. After 7 days of treatment, the coagulation indexes, infection biomarkers and inflammatory cytokines in the Jiedu Limai decoction group were significantly lower than those in the routine treatment group [D-dimer (mg/L): 2.2 (1.8, 8.5) vs. 4.0 (1.5, 8.7), fibrinogen (Fib, g/L): 3.7 (3.4, 4.3) vs. 4.2 (3.7, 4.3), fibrinogen degradation product (FDP, mg/L): 7.2 (5.4, 10.2) vs. 13.2 (9.2, 15.2), procalcitonin (PCT, μg/L): 0.4 (0.2, 2.9) vs. 0.5 (0.2, 0.9), C-reactive protein (CRP, mg/L): 50.1 (9.5, 116.0) vs. 75.1 (23.5, 115.2), interleukin-6 (IL-6, ng/L): 31.6 (21.6, 81.0) vs. 44.1 (14.0, 71.3), all P < 0.05], and the levels of B-type brain natriuretic peptide (BNP) and kidney injury molecule-1 (KIM-1) were significantly lowered [BNP (ng/L): 261.1 (87.5, 360.3) vs. 347.3 (128.8, 439.4), KIM-1 (μg/L): 0.86 (0.01, 1.40) vs. 1.24 (1.05, 1.57), both P < 0.05]. Compared with the routine treatment group, the number of new organ failure in the Jiedu Limai decoction group was decreased (30.0% vs. 50.0%, P < 0.05). Although there was no significant difference in 28-day mortality between the two groups ( P > 0.05), the 28-day mortality in the Jiedu Limai decoction group was lower than that in the routine treatment group (18.0% vs. 24.0%). Conclusion:Combining Jiedu Limai decoction to the sepsis guideline in treating syndrome of heat-toxin exuberance can effectively improve patients' coagulation function, the situation of heart and renal injury, reduce the level of inflammatory cytokines, and fewer people develop new organ failure after treatment.
