Objective:This study aimed to explore the performance of renal resistive index (RRI), semiquantitative power Doppler ultrasound (PDU) score, and renal venous Doppler waveform (RVDW) pattern in predicting 28-day renal dysfunction in critically ill patients and establish nomogram model.Methods:This was a prospective, observational study. Critically ill patients admitted to the emergency intensive care unit (ICU) of Cangzhou Central Hospital from January 2018 to October 2022 were included. Patients underwent renal ultrasound examination to obtain RRI, PDU score and RVDW pattern within 24 h after ICU admission. The following clinical variables were collected during the renal ultrasound examination session, including heart rate, mean arterial pressure, type and dose of vasoactive drugs, oxygen therapy parameters, and average urine volume per hour derived from a period of 6 h prior to the ultrasound examination. The data on duration of AKI and mortality were recorded on the 28th day of follow-up. Patients were divided into 28-day normal renal function group and 28-day renal dysfunction group according to 28-day renal dysfunction. 28-days of renal dysfunction was defined as failure to achieve renal function recovery within 28 days of ICU admission. The difference of each index between the two groups was compared. Associated factors for 28-day renal dysfunction were determined by univariate and multivariate COX regression analyses. A nomogram was developed based on the independently factors associated with 28-day renal dysfunction. Survival receiver operator characteristic (ROC) curves were plotted to assess diagnostic performance in predicting 28-day renal dysfunction. Delong’s test was used to compare area under the curves (AUC) between each predictor.Results:187 patients were enrolled for the final analysis: 97 with no AKI, 48 with AKI stage 1, 24 with AKI stage 2, and 18 with AKI stage 3 upon enrollment. At 28-day follow up, 16 patients had renal dysfunction and 2 required continuous renal replacement therapy (CRRT). The multivariate COX regression showed that RVDW and SCr upon enrollment were the independent risk predictors. Nomogram based on RVDW and SCr upon enrollment showed the best performance in predicting 14-day renal dysfunction (AUC = 0.918, 95% CI:0.871-0.964, P<0.05), and the AUC was statistically significantly higher than single index (all P<0.05). Nomogram also showed the best performance in predicting 28-day renal dysfunction (AUC = 0.924, 95% CI:0.865-0.983, P<0.05), and the AUC was statistically significantly higher than single index (all P<0.05) except for SCr upon enrollment. The optimal cutoff for nomogram in predicting 28-day renal dysfunction was ≤89.5 (sensitivity, 81.2%; specificity, 90.6%; Youden index, 0.719). Kaplan-Meier analysis showed that the median duration of renal dysfunction in the groups with total nomogram score >85.9 and ≤85.9 was 0 and 22 days (HR=0.220, 95% CI:0.129-0.376, P<0.001). Conclusions:SCr and RVDW pattern within 24 h from ICU admission were independent factors associated with 28-day renal dysfunction in critically ill patients. The value of the nomogram model based on these two factors in predicting 28-day renal dysfunction is superior to each single intrarenal Doppler spectrum indicator and clinical indicator.

Objective:To explore the effects of Liuwei Dihuang Wan on the behaviors and Toll-like receptor 4/nuclear factor kappa-B(TLR4/NF-κB) signal transduction pathway of amyloid β-precursor protein/presenilin-1(APP/PS1) double transgenic mice.Methods:Forty 3-month-old female APP/PS1 mice were randomly divided into model group, low-dose group(0.59 g/kg), medium-dose group(1.18 g/kg), high-dose group(2.36 g/kg)of Liuwei Dihuang Wan(gavaged according to grouped doses), and ibuprofen group(0.04 g/kg, gavage) using a random number table method, with 8 mice in each group.Eight 3-month-old wild-type female C57BL/6 mice with matched body weight were used as the control group.The mice in control group and model group were given an equal volume of 0.9% sodium chloride solution by gavage.The gavage administration was twice a day for a continuous period of 3 months.Morris water maze test was used to detect the learning and memory abilities of mice. ELISA was used to detect the serum levels of tumor necrosis factor-α (TNF-α), interleukin-1β(IL-1β) and immunohistochemistry was used to detect the levels of amyloid β-protein (Aβ), glial fibrillary acidic protein(GFAP) and NF-κB in hippocampal tissue.Western blot was used to detect the expression levels of TLR4, myeloid differentiation primary response gene 88(MyD88), and phosphorylated NF-κB(p-NF-κB) proteins in hippocampal tissue.The SPSS 20.0 software was used for data analysis. Multiple group comparisons were conducted by repeated measure ANOVA or one-way ANOVA.Results:The results of repeated measure ANOVA showed that as for the escape latency of the 6 groups of mice, the interaction effect between time and group was significant ( Finteraction=117.219, P<0.001). The escape latencies of mice in the 6 groups on the 5th day were all lower than those on the 1st day (all P<0.05). The escape latencies of mice in the ibuprofen group and the medium-dose and high-dose groups of Liuwei Dihuang Wan were lower than that in the model group from 1st day to 5th day(all P<0.05). On the 3rd to 5th day, the escape latencies of mice in the medium-dose and high-dose groups of Liuwei Dihuang Wan were lower than those in the low-dose group of Liuwei Dihuang Wan (all P<0.05). There were statistically significant differences in the percentage of residence time in the platform quadrant and the numbers of crossing platform among the 6 groups of mice ( F=5.451, 4.824, both P<0.05). The percentage of residence time in the platform quadrant (50.77±5.49)%, (54.39±5.71)%, (51.98±6.12)%), and the numbers of crossing platform((5.9±1.1) times, (6.0±1.3) times, (5.1±0.8) times) in the high-dose and medium-dose groups of Liuwei Dihuang Wan and the ibuprofen group were all higher than those in the model group ((27.32±3.22)%, (2.2±1.0) times )(all P<0.05). The immunohistochemical results showed that there were statistically significant differences in the integrated optical density values of Aβ, GFAP and NF-κB in the hippocampal tissues of 6 groups of mice ( F=57.52, 45.37, 79.10, all P<0.05). The integrated optical density values of Aβ, GFAP and NF-κB in the high-dose and medium-dose groups of Liuwei Dihuang Wan and the ibuprofen group were all lower than those in the model group (all P<0.05). And the integrated optical density values of Aβ, GFAP, and NF-κB in the high-dose and medium-dose groups of Liuwei Dihuang Wan were all lower than those in the low-dose group of Liuwei Dihuang Wan (all P<0.05). There were statistically significant differences in the levels of serum TNF-α and IL-1β detected by ELISA ( F=3.996, 6.395, both P<0.05) and the proteins levels of TLR4, MyD88, and p-NF-κB in hippocampal tissue detected by Western blot among the 6 groups( F=15.710, 3.522, 4.119, all P<0.05). The serum TNF-α and IL-1β levels in the high-dose and medium-dose groups of Liuwei Dihuang Wan and ibuprofen group were all lower than those in the model group (all P<0.05). The serum TNF-α ((18.90±2.33) ng/L, (21.56±2.49) ng/L) and IL-1β ((5.88±0.80) ng/L, (6.75±0.83) ng/L) levels in the high-dose and medium-dose groups of Liuwei Dihuang Wan were lower than those in the low-dose group ((30.77±2.89) ng/L, (9.11±1.27) ng/L) (all P<0.05). The protein expression levels of TLR4, MyD88, and p-NF-κB in the hippocampus of the high-dose and medium-dose groups of Liuwei Dihuang Wan and ibuprofen group were lower than those of the model group (all P<0.05). The protein expression levels of TLR4 ((0.254±0.091), (0.318±0.122)), MyD88 ((0.229±0.077), (0.386±0.119)), and p-NF-κB ((0.412±0.188), (0.358±0.119)) in the hippocampus of the high-dose and medium-dose groups of Liuwei Dihuang Wan were lower than those of the low-dose group ((0.617±0.172), (0.672±0.166), (0.799±0.227)) (all P<0.05). Conclusion:Liuwei Dihuang Wan can significantly alleviate learning and memory impairment in Alzheimer's disease model mice, possibly by inhibiting TLR4/NF-κB signal pathway, reducing TNF-α and IL-1β expression, thereby alleviate central immune inflammatory response and exert anti Alzheimer's disease effects.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective: To investigate the trends in incidence and mortality of gastric cancer in Ningbo City, Zhejiang Province from 2011 to 2022, so as to provide insights into improving gastric cancer control strategy. Methods: The incidence and mortality of gastric cancer in Ningbo City from 2011 to 2022 were collected through Ningbo Municipal Chronic Disease and Cause of Death Monitoring System. The incidence and mortality of gastric cancer were calculated, and standardized by the data from the Sixth Chinese National Population Census in 2020 (Chinese-standardized rate) and the world standard population first introduced by Segi in 1960 (world-standardized rate). The trends in incidence and mortality of gastric cancer were evaluated using annual percent change (APC) and average annual percent change (AAPC). Results : The crude incidence of gastric cancer was 45.69/105 in Ningbo City from 2011 to 2022, with no significant changing patterns seen during the study period (AAPC=-0.02%, P>0.05), and the Chinese- and world-standardized incidence of gastric cancer was 28.61/105 and 21.87/105, which both appeared a tendency towards a decline (AAPC=-3.19% and -3.05%, both P<0.05). The crude, Chinese-standardized and world-standardized mortality rates of gastric cancer were 28.56/105, 17.07/105 and 12.57/105, respectively, all showing a tendency towards a decline (AAPC=-3.00%, -6.26% and -6.34%, all P<0.05). The Chinese- and world-standardized incidence and mortality of gastric cancer all appeared a tendency towards a decline in urban (AAPC=-2.72%, -2.53%, -5.91% and -5.96%, all P<0.05) and rural areas (AAPC=-3.61%, -3.53%, -6.79% and -6.89%, all P<0.05), and the Chinese- and world-standardized incidence and mortality of gastric cancer were significantly higher among urban residents than among rural residents. The Chinese- and world-standardized incidence and mortality of gastric cancer all appeared a tendency towards a decline among men (AAPC=-3.18%, -3.00%, -5.82% and -5.91%, all P<0.05) and women (AAPC=-2.98%, -2.90%, -7.12% and -7.12%, all P<0.05), and the Chinese- and world-standardized incidence and mortality of gastric cancer was significantly higher among men than among women. In addition, the crude incidence and mortality of gastric cancer both appeared a tendency towards a rise with age among residents in Ningbo City (both P<0.05). Conclusions The incidence and mortality of gastric cancer both appeared a tendency towards a decline in Ningbo City from 2011 to 2022; however, the incidence and mortality remained high. Males and urban residents should be given a high priority for gastric cancer control, and gastric cancer screening should be strengthened among individuals at ages of 40 years and older.

Objective: To summarize the clinical characteristics of tumour necrosis factor receptor-associated periodic syndrome (TRAPS) in children. Methods: The clinical manifestations, laboratory tests, genetic testing and follow-up of 10 children with TRAPS from May 2011 to May 2021 in 6 hospitals in China were retrospectively analyzed. Results: Among the 10 patients with TRAPS, including 8 boys and 2 girls. The age of onset was 2 (1, 5) years, the age of diagnosis was (8±4) years, and the time from onset to diagnosis was 3 (1, 7) years. A total of 7 types of TNFRSF1A gene variants were detected, including 5 paternal variations, 1 maternal variation and 4 de novo variations. Six children had a family history of related diseases. Clinical manifestations included recurrent fever in 10 cases, rash in 4 cases, abdominal pain in 6 cases, joint involvement in 6 cases, periorbital edema in 1 case, and myalgia in 4 cases. Two patients had hematological system involvement. The erythrocyte sedimentation rate and C-reactive protein were significantly increased in 10 cases. All patients were negative for autoantibodies. In the course of treatment, 5 cases were treated with glucocorticoids, 7 cases with immunosuppressants, and 7 cases with biological agents. Conclusions: TRAPS is clinically characterized by recurrent fever accompanied by joint, gastrointestinal, skin, and muscle involvement. Inflammatory markers are elevated, and autoantibodies are mostly negative. Treatment mainly involves glucocorticoids, immunosuppressants, and biological agents.

BACKGROUND: Observational research has reported that systemic lupus erythematosus (SLE) is related to common female hormone-dependent cancers, but the underlying causal effect remains undefined. This study aimed to explore the causal association of these conditions by Mendelian randomization (MR) analysis. METHODS: We selected instrumental variables for SLE from genome-wide association studies (GWASs) conducted in European and East Asian populations. The genetic variants for female malignant neoplasms were obtained from corresponding ancestry GWASs. We utilized inverse variance weighted (IVW) as the primary analysis, followed by sensitivity analysis. Furthermore, we conducted multivariable MR (MVMR) to estimate direct effects by adjusting for the body mass index and estradiol. Finally, we implemented reverse direction MR analysis and gave a negative example to test the reliability of MR results. RESULTS: We found SLE was significantly negatively associated with overall endometrial cancer risk (odds ratio [OR] = 0.961, 95% confidence interval [CI] = 0.935-0.987, P  = 3.57E-03) and moderately inversely related to endometrioid endometrial cancer (ENEC) (OR = 0.965, 95% CI = 0.936-0.995, P  = 0.024) risk in the European population by IVW. We replicated these results using other MR models and detected a direct effect by MVMR (overall endometrial cancer, OR = 0.962, 95% CI = 0.941-0.983, P  = 5.11E-04; ENEC, OR = 0.964, 95% CI = 0.940-0.989, P  = 0.005). Moreover, we revealed that SLE was correlated with decreased breast cancer risk (OR = 0.951, 95% CI = 0.918-0.986, P  = 0.006) in the East Asian population by IVW, and the effect was still significant in MVMR (OR = 0.934, 95% CI = 0.859-0.976, P  = 0.002). The statistical powers of positive MR results were all >0.9. CONCLUSION This finding suggests a possible causal effect of SLE on the risk of overall endometrial cancer and breast cancer in European and East Asian populations, respectively, by MR analysis, which compensates for inherent limitations of observational research.

Objective: To investigate the trends in mortality of malignant tumors in Ningbo City, Zhejiang Province from 2002 to 2022, so as to provide the evidence for formulating malignant tumor control strategies in Ningbo City. Methods The data regarding the mortality of malignant tumors in Ningbo City from 2002 to 2022 were collected through the Ningbo Municipal Death Cause Monitoring System, and the crude mortality and age-specific mortality of malignant tumors were calculated in Ningbo City. The mortality of malignant tumors was standardized by the population of the sixth National Population Census in China in 2010 (Chinese-standardized mortality) and the world standard population in 1960 (world-standardized mortality). The trends in mortality of malignant tumors were evaluated with annual percent change (APC) and average annual percent change (AAPC). Methods: The data regarding the mortality of malignant tumors in Ningbo City from 2002 to 2022 were collected through the Ningbo Municipal Death Cause Monitoring System, and the crude mortality and age-specific mortality of malignant tumors were calculated in Ningbo City. The mortality of malignant tumors was standardized by the population of the sixth National Population Census in China in 2010 (Chinese-standardized mortality) and the world standard population in 1960 (world-standardized mortality). The trends in mortality of malignant tumors were evaluated with annual percent change (APC) and average annual percent change (AAPC). Results: The crude mortality of malignant tumors was 186.43/105 to 221.24/105 in Ningbo City from 2002 to 2022, which showed a tendency towards a rise (AAPC=0.76%), and both the Chinese- (AAPC=-2.64%) and world-standardized mortality (AAPC=-2.74%) appeared a tendency towards a decline (all P<0.05). The world-standardized mortality of malignant tumors presented three changes in Ningbo City from 2002 to 2022, with a more remarkable decline from 2011 to 2018 (APC=-3.53%) than from 2002 to 2011 (APC=-2.10%) and from 2018 to 2022 (APC=-2.00%) (all P<0.05). The annual decline in mortality of malignant tumors was higher in men (Chinese-standardized mortality: AAPC=-2.68%; world-standardized mortality: AAPC=-2.75%) than in women (Chinese-standardized mortality: AAPC=-2.45%; world-standardized mortality: AAPC=-2.57%), and higher in urban areas (Chinese-standardized mortality: AAPC=-2.85%; world-standardized mortality: AAPC=-2.92%) than in rural areas (Chinese-standardized mortality: AAPC=-2.45%; world-standardized mortality: AAPC=-2.57%) (all P<0.05). The mortality of malignant tumors appeared a tendency towards a rise with age in Ningbo City, with the highest mortality in residents at ages of 85 years and older (1 447.13/105). Death from malignant tumors were responsible for 31.86% of all causes of death in Ningbo City, and the five most common causes of cancer death included lung cancer, liver cancer, gastric cancer, colorectal cancer and esophageal cancer. In addition, the world-standardized mortality of pancreatic cancer (AAPC=3.92%), prostate cancer (AAPC=4.71%), and cervical cancer (AAPC=1.60%) appeared a tendency towards a rise in Ningbo City (all P<0.05). Conclusions The crude mortality of malignant tumors appeared a tendency towards a rise in Ningbo City from 2002 to 2022, while the standardized mortality showed a tendency towards a decline. Management of malignant tumors should be given a high priority among men and rural residents, and lung cancer, liver cancer, gastric cancer, colorectal cancer and esophageal cancer should be emphasized.

Background Ultrasound-guided continuous thoracic paravertebral block can provide pain-relieving and opioid-sparing effects in patients receiving open hepatectomy. We hypothesize that these effects may improve the quality of recovery (QoR) after open hepatectomy. Methods Seventy-six patients undergoing open hepatectomy were randomized to receive a continuous thoracic paravertebral block with ropivacaine (CTPVB group) or normal saline (control group). All patients received patient-controlled intravenous analgesia with morphine postoperatively for 48 hours. The primary outcome was the global Chinese 15-item Quality of Recovery score on postoperative day 7, which was statistically analyzed using Student's t-test. Results Thirty-six patients in the CTPVB group and 37 in the control group completed the study. Compared to the control group, the CTPVB group had significantly increased global Chinese 15-item Quality of Recovery scores (133.14 ± 12.97 vs. 122.62 ± 14.89, P = 0.002) on postoperative day 7. Postoperative pain scores and cumulative morphine consumption were significantly lower for up to 8 and 48 hours (P < 0.05; P = 0.002), respectively, in the CTPVB group. Conclusion Perioperative CTPVB markably promotes patient's QoR after open hepatectomy with a profound analgesic effect in the early postoperative period.

OBJECTIVES: To investigate the incidence of extrauterine growth retardation (EUGR) and its risk factors in very preterm infants (VPIs) during hospitalization in China. METHODS: A prospective multicenter study was performed on the medical data of 2 514 VPIs who were hospitalized in the department of neonatology in 28 hospitals from 7 areas of China between September 2019 and December 2020. According to the presence or absence of EUGR based on the evaluation of body weight at the corrected gestational age of 36 weeks or at discharge, the VPIs were classified to two groups: EUGR group (n=1 189) and non-EUGR (n=1 325). The clinical features were compared between the two groups, and the incidence of EUGR and risk factors for EUGR were examined. RESULTS: The incidence of EUGR was 47.30% (1 189/2 514) evaluated by weight. The multivariate logistic regression analysis showed that higher weight growth velocity after regaining birth weight and higher cumulative calorie intake during the first week of hospitalization were protective factors against EUGR (P<0.05), while small-for-gestational-age birth, prolonged time to the initiation of total enteral feeding, prolonged cumulative fasting time, lower breast milk intake before starting human milk fortifiers, prolonged time to the initiation of full fortified feeding, and moderate-to-severe bronchopulmonary dysplasia were risk factors for EUGR (P<0.05). CONCLUSIONS It is crucial to reduce the incidence of EUGR by achieving total enteral feeding as early as possible, strengthening breastfeeding, increasing calorie intake in the first week after birth, improving the velocity of weight gain, and preventing moderate-severe bronchopulmonary dysplasia in VPIs.

ObjectiveTo investigate the protective effect of Zhizi prescription （ZZP） on carbon tetrachloride （CCl₄）-induced acute and subacute liver injury and its mechanism. MethodAcute and subacute liver injury animal models were induced. C57 mice were randomly divided into a normal group， model group， obeccholic acid group， ZZP high-dose （0.5 g·kg^-1） group， and ZZP low-dose （0.25 g·kg^-1） group. According to the experiment design， the serum and liver tissue of mice were collected after the last administration. Hematoxylin-eosin （HE） and Sirius staining was used to observe the liver pathological changes. Serum alanine aminotransferase （ALT）， aspartate aminotransferase （AST）， total bilirubin （TBIL）， liver homogenate hydroxyproline （Hyp）， malondialdehyde （MDA）， and superoxide dismutase （SOD） levels were determined by kit. The levels of tumor necrosis factor-α （TNF-α） and interleukin-6 （IL-6） in the liver tissue were determined by enzyme-linked immunosorbent assay （ELISA）. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was used to detect the mRNA expressions of collagen 1A1 （Col1a1）， collagen 3A1 （Col3a1）， fibronectin （FN）， transforming growth factor β receptor Ⅱ （Tgfbr2） and α-smooth muscle actin （α-SMA） in the liver tissue. ResultIn terms of the acute liver injury， as compared with the normal group， the levels of ALT， AST， TBIL and MDA in the model group were significantly increased （P<0.01）， while the activity of liver SOD was significantly decreased （P<0.01）. Compared with model group， the ZZP high-dose and low-dose groups both significantly reduced the degree of liver cell injury， and protected the acute liver injury induced by CCl₄. The ZZP high-dose group had a better effect than the ZZP low-dose group. In terms of the subacute liver injury， the levels of ALT， AST， MDA，TNF-α and IL-6 in the model group were significantly increased （P<0.01）， while the activity of liver SOD was significantly decreased （P<0.01）. As compared with the model group， liver Hyp content in the ZZP high-dose and low-dose groups was significantly decreased （P<0.01）， and the collagen deposition in liver of both groups was significantly reduced. The ZZP high-dose group also significantly down-regulated the mRNA expressions of α-SMA， Col1a1， Col3a1， FN， and Tgfbr2 in the liver of mice （P<0.05， P<0.01）. ConclusionZZP effectively protects the acute and subacute liver injury induced by CCl₄， and the protective effect is proportional to its concentration. The mechanism may be related to the increase of the activity of antioxidant enzymes in the liver tissue， the decrease of the level of lipid peroxidation， and the inhibition of inflammatory response， thus reducing collagen deposition and improving early liver fibrosis.
