Objective:To investigate the effects of different plasma/red blood cell suspension ratios on prothrombin time (PT), activated partial thromboplastin time (APTT), and fibrinogen (Fb) level in patients with postpartum hemorrhage, providing evidence for rational blood transfusion in clinical practice.Methods:This study used a retrospective design. The clinical data of 128 patients with postpartum hemorrhage admitted to Jinan Central Hospital from January 2020 to December 2023 were analyzed. The patients were divided into a control group and an observation group, with 64 patients in each group, based on different transfusion protocols. The control group received transfusion therapy using a conventional plasma/red blood cell suspension ratio, while the observation group was treated with an optimized ratio scheme. The PT, APTT, and Fb levels were compared between the two groups before and after blood transfusion. The amount of bleeding, the volume of blood transfused, and the incidence of complications were recorded and compared between the two groups.Results:Before transfusion, there were no statistically significant differences in PT, APTT, or Fb levels between the two groups (all P>0.05). After transfusion, PT and APTT in the observation group were (11.53 ± 1.08) seconds and (32.00 ± 3.00) seconds, respectively, which were significantly shorter than those in the control group [(13.02 ± 1.57) seconds, (35.00 ± 4.00) seconds, t = 8.01, 6.01, both P<0.001]. Fb levels in the observation group were significantly higher than those in the control group [(2.24 ± 0.37) g/L vs. (1.83 ± 0.47) g/L, t = 5.48, P<0.001]. The amount of bleeding and the volume of red blood cell suspension transfused in the observation group were (800 ± 150) mL and (600 ± 80) mL, respectively, which were significantly lower than those in the control group [ (1 200 ± 200) mL, (800 ± 100) mL, t = 12.01, 10.01, both P<0.001]. There was no statistically significant difference in the volume of blood transfused between the two groups ( t = 0.00, P = 1.000). The incidence of complications in the observation group was significantly lower than that in the control group [10.94% (7/64) vs. 20.31% (13/64), χ2 = 4.60, P = 0.032]. Conclusions:The optimized plasma/red blood cell suspension ratio can effectively improve the coagulation function of patients with postpartum hemorrhage, reduce bleeding and transfusion-related complications.

Objective To investigate the association between baseline depression and the risk of type 2 diabetes mellitus(T2DM)in middle-aged and elderly people in Chengguan District of Lanzhou.Methods A total of 4471 residents who were followed up in Chengguan District,Lanzhou City from August 2014 to July 2016 in the 2011 REACTION study were selected as the research subjects.According to the 9-item patient health questionnaire(PHQ-9),they were divided into the non-depression group with a score of 0～4 points(ND,n=3827),the mild depression group with a score of 5～10 points(MD,n=546)and the moderate to severe depression group with a score of≥10 points(MSD,n=98).The general data and biochemical indicators of the three groups were compared.The correlation between depression status and glycolipid metabolism indicators was analyzed.The follow-up results of the three groups with different baseline glucose metabolism status populations were compared.Logistic regression was used to analyze the influencing factors of progression in different glucose metabolism populations.Results The married rate in the ND,MD and MSD groups decreased sequentially(P<0.05),while the rate of living alone and the PHQ-9 score increased(P<0.05).The female population,family history of DM,coronary heart disease,LDL-C and TC in the MD group were higher than those in the ND group(P<0.05),while the age,BMI,WHR,FPG and 2 hPG in the MD group were lower than those in the ND group(P<0.05).The family history of DM in the MSD group was higher than those in the ND group(P<0.05),drinking and LDL-C in the MSD group were higher than those in the MD group(P<0.05),the BMI was lower than that in the ND group(P<0.05).Spearman correlation analysis showed that the baseline PHQ-9 score was negatively correlated with FPG level(r=-0.039,P<0.05),and positively correlated with HDL-C and TC(r=0.049,0.031,P<0.05).There was no significant difference in the incidence of pre-DM and T2DM at the end of follow-up among the three groups with different baseline glucose metabolism(P>0.05).Logistic regression analysis showed that after adjusting for confounding factors,the risk of pre-DM and T2DM in normal glucose tolerance people with different depression status and the risk of T2DM in pre-DM patients were not increased.Conclusions Depressive state may not be the main factor affecting the occurrence of T2DM in middle-aged and elderly people in Chengguan District of Lanzhou.

Intra-abdominal candidiasis (IAC) is the most common invasive candidiasis, with a high incidence among critically ill patients, which can significantly increase medical costs and affect prognosis. In order to standardize the diagnosis and treatment of IAC in critically ill patients, experts in related fields were organized by the Peking University Critical Care Medicine (PKUCCM), Committee of Critical Care Medicine and Organ Support, China Association for Promotion of Health Science and Technology organized experts in related fields to initiate and form a working group. Expert writers drafted the consensus based on evidence-based medical evidence. A committee composed of critical care physicians, infectious disease physicians, surgeons, dermatologists specializing in antifungal fields, and clinical pharmacists discussed and revised the consensus draft through a standardized process, and finally formulated this consensus. This consensus contains a total of 20 core recommendations, mainly focusing on the epidemiology, high-risk factors, diagnostic techniques and methods (including traditional microbiological culture techniques, clinical risk prediction tools, serological tests, molecular biological tests, and histopathological examinations) of IAC, diagnostic criteria, stratified treatment strategies, antifungal drug selection, control the sources of infection, combined treatment, de-escalation strategies, drug treatment courses, prognosis, and special types of IAC. The aim is to provide expert guidance for the standardized clinical diagnosis and treatment of IAC in critically ill patients, with a view to improving prognosis of patients.

We conducted a prospective study to assess the non-inferiority of adjuvant chemotherapy alone versus adjuvant concurrent chemoradiotherapy (CCRT) as an alternative strategy for patients with early-stage (FIGO 2009 stage IB-IIA) cervical cancer having risk factors after surgery. The condition was assessed in terms of prognosis, adverse effects, and quality of life. This randomized trial involved nine centers across China. Eligible patients were randomized to receive adjuvant chemotherapy or CCRT after surgery. The primary end-point was progression-free survival (PFS). From December 2012 to December 2014, 337 patients were subjected to randomization. Final analysis included 329 patients, including 165 in the adjuvant chemotherapy group and 164 in the adjuvant CCRT group. The median follow-up was 72.1 months. The three-year PFS rates were both 91.9%, and the five-year OS was 90.6% versus 90.0% in adjuvant chemotherapy and CCRT groups, respectively. No significant differences were observed in the PFS or OS between groups. The adjusted HR for PFS was 0.854 (95% confidence interval 0.415-1.757; P = 0.667) favoring adjuvant chemotherapy, excluding the predefined non-inferiority boundary of 1.9. The chemotherapy group showed a tendency toward good quality of life. In comparison with post-operative adjuvant CCRT, adjuvant chemotherapy treatment showed non-inferior efficacy in patients with early-stage cervical cancer having pathological risk factors. Adjuvant chemotherapy alone is a favorable alternative post-operative treatment.

Objective:To compare the short-term clinical effect of arthroscopic and open reduction and internal fixation with Herbert screws in treatment of Mason type II radial head fractures.Methods:A retrospective case-control study was conducted to analyze the clinical data of 38 patients with unilateral radial head fractures (Mason type II) admitted to Shanghai Zhongye Hospital from January 2017 to December 2018, including 22 males and 16 females, aged from 20 to 65 years [(37.4±12.6)years]. Twenty patients were treated by arthroscopic reduction and internal fixation with Herbert screw (Group A), and eighteen by open reduction and internal fixation with Herbert screw (Group B). The operation time and fracture healing time were recorded. The visual analogue scale (VAS), elbow flexion and extension range, forearm rotation range and Mayo elbow function score were compared between the two groups before and at 1, 3, 6, and 12 months after operation. The results of Mayo elbow performance score (MEPS) and upper limb function assessment using the disabilites of the arm, shoulder, and hand (DASH) score were compared between the two groups. Complications including screw breakage or fracture displacement were also evaluated.Results:All patients were followed up for 12-14 months [(12.3±2.3)months]. There was no significant difference in operation time between the two groups ( P>0.05). The fracture healing time was (8.9±0.6)weeks in Group A and (8.7±0.6)weeks in Group B ( P>0.05). There was no significant difference in VAS between the two groups before operation ( P>0.05). The VAS was (4.8±0.5)points at 1 month after operation in Group A, lower than (6.0±0.7)points in Group B ( P<0.05). There was no significant difference in VAS between Group A and Group B at 3, 6, and 12 months after operation ( P>0.05). There was no significant difference in elbow flexion and extension range between the two groups before operation ( P>0.05). The elbow flexion and extension range in Group A was (110.4±3.8)° and (137.1±4.0)° at 1, 3 months after operation, which was significant greater than (90.6±4.7)° and (125.1±3.5)° in Group B ( P<0.05). There was no significant difference in elbow flexion and extension range between the two groups at 6 and 12 months after operation ( P>0.05). There was no significant difference in the range of forearm rotation between the two groups before operation ( P>0.05). The range of forearm rotation in Group A was (107.1±2.8)° and (138.1±2.9)° at 1, 3 months after operation, significantly greater than (95.5±3.9)°, (121.5±3.0)° in Group B ( P<0.05). There was no significant difference in forearm rotation range between the two groups at 6 and 12 months after surgery ( P>0.05). There was no significant difference in MEPS between the two groups before operation ( P>0.05). The MEPS in Group A was (50.4±3.8)points at 1 month after operation, higher than (40.6±4.7)points in Group B ( P<0.05). There was no significant difference in MEPS between the two groups at 3, 6, and 12 months after operation ( P>0.05). There was no significant difference in DASH score between the two groups before operation ( P>0.05). The DASH score was (57.1±2.8)points at 1 month after surgery in Group A, higher than (42.5±3.9)points in Group B ( P<0.05). The DASH score was not significantly different between the two groups at 3, 6, and 12 months after operation ( P>0.05). There was no screw loosening or fracture after operation, and one patient in each group had fracture displacement ( P>0.05). Conclusion:For Mason type II radial head fractures, arthroscopic Herbert screw fixation has the advantages of less trauma, less pain and faster functional recovery of the affected limb compared with open reduction and Herbert screw fixation.

Objective:To investigate the different outcomes of two types of acute kidney injury (AKI) according to standard of Kidney Disease: Improving Global Outcomes-AKI (KDIGO-AKI), and to analyze the risk factors that affect the prognosis of intensive care unit (ICU) patients in China.Methods:A secondary analysis was performed on the database of a previous study conducted by China Critical Care Clinical Trial Group (CCCCTG), which was a multicenter prospective study involving 3 063 patients in 22 tertiary ICUs in 19 provinces and autonomous regions of China. The demographic data, scores reflecting severity of illness, laboratory findings, intervention during ICU stay were extracted. All patients were divided into pure AKI (PAKI) and acute on chronic kidney disease (AoCKD). PAKI was defined as meeting the serum creatinine (SCr) standard of KDIGO-AKI (KDIGO-AKI SCr) and the estimated glomerular filtration rate (eGFR) at baseline was ≥ 60 mL·min -1·1.73 m -2, and AoCKD was defined as meeting the KDIGO-AKI SCr standard and baseline eGFR was 15-59 mL·min -1·1.73 m -2. All-cause mortality in ICU within 28 days was the primary outcome, while the length of ICU stay and renal replacement therapy (RRT) were the secondary outcome. The differences in baseline data and outcomes between the two groups were compared. The cumulative survival rate of ICU within 28 days was analyzed by Kaplan-Meier survival curve, and the risk factors of ICU death within 28 days were screened by Cox multivariate analysis. Results:Of the 3 063 patients, 1 042 were enrolled, 345 with AKI, 697 without AKI. The AKI incidence was 33.11%, while ICU mortality within 28 days of AKI patients was 13.91% (48/345). Compared with PAKI patients ( n = 322), AoCKD patients ( n = 23) were older [years old: 74 (59, 77) vs. 58 (41, 72)] and more critical when entering ICU [acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) score: 23 (19, 27) vs. 15 (11, 22)], had worse basic renal function [eGFR (mL·min -1·1.73 m -2): 49 (38, 54) vs. 115 (94, 136)], more basic complications [Charlson comorbidity index (CCI): 3 (2, 4) vs. 0 (0, 1)] and higher SCr during ICU stay [peak SCr for diagnosis of AKI (μmol/L): 412 (280, 515) vs. 176 (124, 340), all P < 0.01]. The mortality and RRT incidence within 28 days in ICU of AoCKD patients were significantly higher than those of PAKI patients [39.13% (9/23) vs. 12.11% (39/322), 26.09% (6/23) vs. 4.04% (13/322), both P < 0.01], while no significant difference was found in the length of ICU stay. Kaplan-Meier survival curve analysis showed that the 28-day cumulative survival rate in ICU in AoCKD patients was significantly lower than PAKI patients (Log-Rank: χ2 = 5.939, P = 0.015). Multivariate Cox regression analysis showed that admission to ICU due to respiratory failure [hazard ratio ( HR) = 4.458, 95% confidence interval (95% CI) was 1.141-17.413, P = 0.032], vasoactive agents treatment in ICU ( HR = 5.181, 95% CI was 2.033-13.199, P = 0.001), and AoCKD ( HR = 5.377, 95% CI was 1.303-22.186, P = 0.020) were independent risk factors for ICU death within 28 days. Conclusion:Further detailed classification (PAKI, AoCKD) based on KDIGO-AKI SCr standard combined with eGFR is related to ICU mortality in critical patients within 28 days.

Objectives:To analyze the effect of cytokine-like protein 1 (CYTL1) on the pro-inflammatory functions of neutrophils in septic mice.Methods:C57BL/6 mice were randomly (random number)divided into the sepsis group and control group, with 6-12 mice in each group. A septic mouse model was established by the procedure of cecal ligation and puncture (CLP). Neutrophils were isolated from peripheral venous blood 8 h after the procedures according to the density gradient centrifugation method, and the neutrophils were treated with CYTL1 recombinant protein. The Boyden chemotaxis assays were used to detect the activity of CYTL1. fMLF and interleukin-8 were used as positive controls. Phagocytosis was determined by confocal microscopy or on a FACSVerse. Reactive oxygen species generation in neutrophils were monitored with the commercial CellROX Green fluorescent probe.Results:Compared with the control group, CYTL1 showed strong chemotactic activity on neutrophils of septic mice [(10.0 ± 2) vs (66.3 ± 4), t=-21.6, P <0.0001]. CYTL1 has stronger chemotactic activity than IL-8 [(66.3 ± 4.0) vs (21.7 ± 6.5), t = 10.1, P = 0.001]. But the chemotactic activity of fMLF and CYTL1 changed little on neutrophils of septic mice [(66.3 ± 4.0) vs (86.0 ± 13.5), t=-2.4, P = 0.073]. CYTL1 could augment the uptake of E.coli by neutrophils compared with the sepsis group [(7.35 ± 1.66) vs (2.84 ± 0.62), t = 4.4, P = 0.012]. The number of E.coli particles swallowed intracellular by a single cell significantly increased upon the stimulation of CYTL1. CYTL1 could also enhance the intracellular reactive oxygen species production of neutrophils of septic mice [(84340.1 ± 5353.5) vs (351018.7 ± 72291.7), t = 6.4, P = 0.003]. Conclusions:CYTL1 can prompt the pro-inflammatory functions of neutrophils in septic mice. In the early phase of bacterial infection, this protein may play an important role in regulating the inflammation.

Objective To detect the plasma concentrations of daptomycin in the left ventricle and right ventricle of rats by high-performance liquid chromatography-mass spectrometry(LC-MS/MS), and evaluate the therapeutic effect of daptomycin on left ventricular endocarditis. Methods Thirty-five healthy Sprague-Dawley (SD) rats were divided into a normal saline group (5 rats) and a daptomycin group (30 rats) according to the random number table method. The daptomycin group was subdivided into 6 subgroups according to the times of blood collection (0.25, 0.5, 1, 2, 4, 8 hours), with 5 rats in each subgroup. The normal saline group was given 4 mL/kg normal saline; the daptomycin group was injected with 50 mg/kg daptomycin into the tail vein. The blood samples from left ventricle and right ventricle were extracted at the corresponding time points, the plasma concentrations of daptomycin group were determined by high performance liquid chromatography-mass spectrometry (HPLC-MS) and the differences of left ventricular and right ventricular plasma concentrations were compared at different time points. The plasma in normal saline group was the blank plasma that was used for HPLC-MS methodological evaluation. Results There were no statistical significant differences between the left ventricle and right ventricle in plasma concentrations of daptomycin at 0.25, 0.5, 1, 2, 4, and 8 hours after administration (g/L: 2.67±0.30 vs. 2.77±0.31, 1.77±1.27 vs. 1.64±0.55, 1.35±0.40 vs. 1.36±0.41, 0.97±0.07 vs. 0.92±0.09, 0.73±0.16 vs. 0.65±0.18, 0.07±0.06 vs. 0.06±0.05, respectively all P > 0.05). Conclusion There are no significant differences between the left ventricle and right ventricle in plasma concentrations of daptomycin. It is speculated that daptomycin may have the same therapeutic effect on left endocarditis.
