Cardiac fibrosis(CF) is a cardiac pathological process characterized by excessive deposition of extracellular matrix(ECM). When the heart is damaged by adverse stimuli, cardiac fibroblasts are activated and secrete a large amount of ECM, leading to changes in cardiac fibrosis, myocardial stiffness, and cardiac function declines and accelerating the development of heart failure. There is a close relationship between heart yin deficiency and cardiac fibrosis, which have similar pathogenic mechanisms. Heart Yin deficiency, characterized by insufficient Yin fluids, causes the heart to lose its nourishing function, which acts as the initiating factor for myocardial dystrophy. The deficiency of body fluids leads to stagnation of blood flow, resulting in blood stasis and water retention. Blood stasis and water retention accumulate in the heart, which aligns with the pathological manifestation of excessive deposition of ECM, as a tangible pathogenic factor. This is an inevitable stage of the disease process. The lingering of blood stasis combined with water retention eventually leads to the generation of heat and toxins, triggering inflammatory responses similar to heat toxins, which continuously stimulate the heart and cause the ultimate outcome of CF. Considering the syndrome of heart Yin deficiency, traditional Chinese medicine capable of nourishing Yin, activating blood, and promoting urination can reduce myocardial cell apoptosis, inhibit fibroblast activation, and lower the inflammation level, showing significant advantages in combating CF.

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 effects of astragaloside IV (AS-IV) on acute myocardial injury in rats with high-level spinal cord injury (SCI).Methods:Twenty-four healthy male SD rats, aged 8-10 weeks with a body weight of 250-300 g, were randomly divided into 4 groups using a random number table method: sham operation group, high-level SCI group (SCI group), high-level SCI+AS-IV group (SCI+AS-IV group) and high-level SCI+AS-IV+silent information regulator 1 (SIRT1) inhibitor EX527 group (SCI+AS-IV+EX527 group), with 6 rats in each group. The SCI model was established using the modified Allen method and the sham operation group underwent the spinal cord exposure only. In the SCI+AS-IV group, 40 mg/kg of AS-IV was injected intraperitoneally immediately after injury. SCI+AS-IV+EX527 group received an intraperitoneal injection of 5 mg/kg EX527 at one hour before injury and another injection of 40 mg/kg AS-IV in the same way immediately after injury. The sham operation group and the SCI group received an equal volume of saline via intraperitoneal injection. Immediately after awakening from injury, the hind limb motor function of the rats in each group was observed, recorded and then evaluated using the BBB method. At 24 hours after injury, the ultrastructure of the cardiomyocytes was examined under a transmission electron microscope; the levels of serum cardiac troponin I (cTnI), myocardial tissue inflammatory factors interleukin (IL)-18 and IL-1β were quantified by the ELISA method; the level of reactive oxygen species (ROS) of the myocardial tissue was assessed utilizing the dihydroethidium (DHE) assay; biochemical analyses were employed to determine the superoxide dismutase (SOD) activity and malondialdehyde (MDA) concentrations; mRNA and protein expression levels of nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3), cysteinyl aspartate specific proteinase-1 (caspase-1), gasdermin D (GSDMD), SIRT1 and peroxisome proliferator-activated receptor γ coactivator-1α (PGC-1α) were examined using RT-PCR and Western blot; cardiomyocyte pyroptosis rate was evaluated by caspase-1 and TUNEL double-labeled fluorescence staining.Results:Immediately after awakening from injury, the sham operation group exhibited normal hind limb activity, with BBB scores of 21(21, 21)points, while the remaining groups displayed flaccid paralysis in both hind limbs, accompanied by the cessation of spontaneous excretion, with BBB scores of 0(0, 0)points.

At 24 hours after injury, caspase-1 and TUNEL double-labeled fluorescence staining showed that the cardiomyocyte pyroptosis rate in the SCI group was (34.5±6.7)%, higher than (5.3±2.9)% in the sham operation group ( P<0.01); the cardiomyocyte pyroptosis rate in the SCI+AS-IV group was (13.4±3.0)%, lower than that in the SCI group ( P<0.01); the cardiomyocyte pyroptosis rate in the SCI+AS-IV+EX527 group was (22.5±5.9)%, higher than that in the SCI+AS-IV group ( P<0.01), yet lower than that in the SCI group ( P<0.01). Conclusions:AS-IV can significantly reduce acute myocardial injury in rats with high-level SCI. Its mechanism may involve activating the myocardial SIRT1/PGC-1α signaling pathway, protecting the mitochondria, enhancing the ability to resist oxidative stress, and effectively inhibiting the NLRP3 inflammasome-mediated pyroptosis pathway.

Objective: To investigate the pulmonary functions among the elderly in Hangzhou City, so as to provide insights into the management of respiratory diseases among the elderly. Methods: Permanent residents at ages of 60 to 75 years were sampled from Hangzhou City from November to December 2020. The pulmonary function was tested using a portable pulmonary function monitor, including large airway function parameters [forced expiratory volume (FVC), forced expiratory volume in a second (FEV1) and FEV1/FVC], and small airway function parameters [maximum expiratory flow rate at 75% vital capacity (MEF75%), the maximum expiratory flow rate at 25% of vital capacity (MEF25%) and the forced expiratory flow rate (FEF25%-75%) at 25% to 75% of vital capacity]. The pulmonary functions were compared among the elderly with different genders, ages and body mass index (BMI). Results : Totally 314 participants were recruited, including 126 men (40.13%), with a mean age of (68.49±4.47) years and mean BMI of (23.51±2.79) kg/m2. The mean FEV1, FVC, FEV1/FVC, MEF25%, MEF75% and FEF25%-75% were (1.97±0.53) L, (2.51±0.72) L, (79.79±11.47)%, (0.98±0.53) L/s, (3.84±1.65) L/s and (1.99±0.91) L/s among the participants, respectively. Higher FEV1 [(2.22±0.55) vs. (1.79±0.43) L, P<0.05], FVC [(2.92±0.75) vs. (2.24±0.55) L, P<0.05], MEF75% [(4.19±1.82) vs. (3.59±1.49) L/s, P<0.05] and FEF25%-75% [(2.14±1.07) vs. (1.90±0.77) L/s, P<0.05] were tested among men than among women, and lower FEV1 [(1.75±0.46) L], FVC [(2.27±0.64) L], MEF25% [(0.88±0.57) L/s], MEF75% [(3.39±1.45) L/s] and FEF25%-75% [(1.79±0.96) L/s] were tested among the elderly at ages of 70 to 74 years. The proportion of large and small airway dysfunctions was 40.45% among the participants. Conclusions The proportion of large and small airway dysfunctions was 40.45% among the elderly in Hangzhou City, and poor pulmonary functions were tested among the women and the advanced elderly.

Objective To construct luciferase reporter plasmids of truncated fragments of different lengths of human guanylate binding protein 5(GBP5)gene promoter and analyze the transcriptional activity of each fragment to determine the core regulatory region.Methods GBP5promoter sequence was amplified by PCR,truncated into five fragments of different lengths and connected to pGL3-basic plasmid.The constructed recombinant plasmids pGL3-GBP5-11/21/31/41/51were transfected into 293FT cells and detected for luciferase activity.The binding sites of transcription factors in GBP5promoter region were predicted by JASPAR software,and Yin-Yang transcription factor 1(YY1)targeting the core regulatory region was selected and verified for the transcriptional regulatory activity.The CDS sequence of YY1 was amplified by PCR to construct the overexpression plasmid pIRES2-EGFP-YY1,which was then co-transfected to 293FT cells with plasmids pGL3-GBP5-21(-1 623 ～ +47 bp)and internal reference plasmid pRL-CMV,and detected for luciferase activity to analyze the regulation of transcription factor YY1 on GBP5 promoter activity.Results Colony PCR and double enzyme digestion identification proved that the plasmid of human GBP5 promoter reporter gene was correctly constructed;JASPAR software predicted that there were multiple transcription factor binding sites such as STAT1,YY1 and Foxp3 in GBP5promoter region.Double luciferase activity assay showed that pGL3-GBP5-21(-1 623 ～ +47 bp)showed the highest promoter activity,while the promoter activity of pGL3-GBP5-41(-520 ～ +47 bp)decreased significantly,suggesting that the core region of GBP5 promoter was located at upstream-1 623 ～-520 bp of 5 'UTR;Overexpression of YY1 significantly activated the GBP5 promoter activity and regulated the expression of GBP5.Conclusion The core regulatory region of human GBP5 promoter was located in upstream-1 623 ～-520 bp of the 5 'UTR,with a binding site of transcription factor YY1 existing in this region.Meanwhile,overexpression of YY1 significantly effected the activity of GBP5 promoter.

The Guidelines for prevention and treatment of colorectal adenoma with integrated Chinese and western medicine are put forward by Nanjing University of Chinese Medicine and approved by China Association of Chinese Medicine. According to the formulation processes and methods of relevant clinical practice guidelines, the experts in clinical medicine and methodology were organized to discuss the key problems to be addressed in the clinical prevention and treatment of colorectal adenoma(CRA) and provided answers following the evidence-based medicine method, so as to provide guidance for clinical decision-making. CRA is the major precancerous disease of colorectal cancer. Although the prevention and treatment with integrated Chinese and western medicine have been applied to the clinical practice of CRA, there is still a lack of high-quality guidelines. Four basic questions, 15 clinical questions, and 10 outcome indicators were determined by literature research and Delphi questionnaire. The relevant randomized controlled trial(RCT) was retrieved from CNKI, Wanfang, VIP, SinoMed, PubMed, EMbase, Cochrane Library, Web of Science, and 2 clinical trial registries, and finally several RCTs meeting the inclusion criteria were included. The data extracted from the RCT was imported into RevMan 5.3 for evidence synthesis, and the evidence was evaluated based on the Grading of Recommendations, Assessment, Development, and Evaluations(GRADE). The final recommendations were formed by the nominal group method based on the evidence summary table. The guidelines involve the diagnosis, screening, treatment with integrated Chinese and western medicine, prevention, and follow-up of colorectal adenoma, providing options for the clinical prevention and treatment of CRA.

Objective:To investigate the changes of autonomic nervous active substances in myocardium of rats with acute high-level spinal cord injury.Methods:Twenty-four clean-level healthy adult male SD rats weighting 250-300 g for 8-10 weeks old were divided into control group ( n=6) and spinal cord injury group ( n=18) according to the random number table. The spinal cord injury group was subdivided at 4, 12 and 24 hours, with 6 rats at each time point. The high-level spinal cord injury model was established by the modified Allen′s weight-drop method, and the spinal cord was only exposed in control group. The postoperative performance and BBB score for limb movement were observed in each group. The myocardium of each group was resected and used to observe ultrastructure of myocardial cells under transmission electron microscope and detect protein and mRNA levels of tyrosine hydroxylase (TH), noradrenaline transporter (NET), acetylcholinesterase (AChE) and choline acetyltransferase (ChAT) by Western blot and RT-PCR analysis. Results:Rats of control group showed normal limb motion after operation without significant change from the preoperation level, and mean BBB score was 21 points. Rats of spinal cord injury group showed significantly reduced activities and feeding, with flaccid paralysis of both lower limbs as well as no spontaneous excretion, and showed BBB score of 0 point at 4 hours and 12 hours after injury, which was increased slightly at 24 hours after injury, with the highest score for 1 point. The ultrastructure of myocardial cells showed no obvious abnormalities in control group, while different degrees of changes in spinal cord injury group. Compared with control group, Western blot analysis showed that protein levels of TH and NET were decreased, while AChE and ChAT were increased in spinal cord injury group ( P<0.05 or 0.01). Compared with control group, RT-PCR analysis showed that mRNA levels of TH and NET were decreased, while AChE and ChAT were increased in spinal cord injury group ( P<0.05 or 0.01). mRNA levels of TH and NET in spinal cord injury group at 24 hours after injury were significantly different from those at 4 hours and 12 hours after injury (all P<0.05). mRNA levels of ChAT in spinal cord injury group were statistically significant at 12 hours and 24 hours after injury from those at 4 hours after injury, with significant difference at 12 hours and 24 hours after injury (all P<0.05). Conclusion:Sympathetic nerve active substances TH and NET are down-regulated but vagal nerve active substances AChE and ChAT up-regulated in myocardium of rats with acute high-level spinal cord injury, which may be related to the relative excitation of the parasympathetic nerve blocking the sympathetic innervation of the higher center to the heart following high-level spinal cord injury.

Objective:To study the clinical characteristics of neonatal sepsis caused by raoultella ornithinolytica.Methods:From January 2010 to December 2020, clinical data of seven cases of neonates with raoultella ornithinolytica sepsis in the Department of Neonatology of our hospital were analyzed. Literature published from the establishment of the databases to December 31, 2020 were searched and reviewed on this topic. The databases included PubMed, Web of Science, Embase database, Wanfang Database, CNKI, National Science and Technology Library and Chinese Science Paper Online.Results:Among the 7 cases admitted to our hospital, 6 male and 1 female, 6 premature and 1 full-term small-for-gestational-age (SGA), 6 patients presented with lethargy, 5 patients had fever and 3 showed dyspnea. 4 patients had necrotizing enterocolitis (NEC), 1 congenital intestinal malrotation, 1 congenital jejunal atresia, 1 intestinal adhesion and stricture. 4 patients had history of surgery. Leucocytosis was found in 3 cases and leukopenia in 1 case. Thrombocytopenia and increased inflammatory indicators were found in all cases. All 7 patients recovered and were discharged. 4 articles on 4 newborn cases (3 males, 1 female including two premature infants) were found for literature review. 3 cases had skin flushing, 3 cases showed dyspnea, 2 cases had fever and 1 case presented with lethargy. 1 case received surgery for congenital heart disease. Leucocytosis was found in 2 cases, leukopenia in 1 case, thrombocytopenia in 2 cases and elevated inflammatory indicators in 3 cases. 1 patient died due to septic shock and the other three recovered and were discharged.Conclusions:Raoultella ornithinolytica neonatal sepsis may occur in infants with intestinal comorbidities, history of invasive procedures, premature birth or full-term SGA and congenital malformations. Most anti-infective therapies are effective. However, if the patient had septic shock, the prognosis is poor.

OBJECTIVE: To explore the mechanism underlying the hepatoprotective effect of dihydromyricetin (DMY) against lipid accumulation in light of the lipophagy pathway and the inhibitory effect of DMY on HepG2 cell proliferation. METHODS: LO2 cells were cultured in the presence of 10% FBS for 24 h and treated with 100 μg/mL DMY, or exposed to 50% FBS for 24 h followed by treatment with 50, 100, or 200 μg/mL DMY; the cells in recovery group were cultured in 50% FBS for 24 h and then in 10% FBS for another 24 h. Oil red O staining was used to observe the accumulation of lipid droplets in the cells, and the levels of TC, TG, and LDL and activities of AST, ALT and LDH were measured. The expression of LC3 protein was detected using Western blotting. AO staining and transmission electron microscopy were used to determine the numbers of autophagolysosomes and autophagosomes, respectively. The formation of autophagosomes was observed with MDC staining, and the mRNA expression levels of LC3, ATG7, AMPK, mTOR, p62 and Beclin1 were determined with q-PCR. Flow cytometry was performed to analyze the effect of 50, 100, and 200 μg/mL DMY on cell cycle and apoptosis of HepG2 cells; DNA integrity in the treated cells was examined with cell DNA fragmentation test. RESULTS: DMY treatment and pretreatment obviously inhibited lipid accumulation and reduced the levels of TC, TG, LDL and enzyme activities of AST, ALT and LDH in LO2 cells (P < 0.05). In routinely cultured LO2 cells, DMY significantly promoted the formation of autophagosomes and autophagolysosomes and upregulated the expression of LC3 protein. DMY obviously attenuated high FBS-induced inhibition of autophagosome formation in LO2 cells, up- regulated the mRNA levels of LC3, ATG7, Beclin1 and AMPK, and downregulated p62 and mTOR mRNA levels (P < 0.05 or 0.01). In HepG2 cells, DMY caused obvious cell cycle arrest, inhibited cell proliferation, and induced late apoptosis and DNA fragmentation. CONCLUSION DMY reduces lipid accumulation in LO2 cells by regulating the AMPK/ mTOR-mediated lipophagy pathway and inhibits the proliferation of HepG2 by causing cell cycle arrest and promoting apoptosis.

Objective: To investigate death and attrition in HIV-infected children under initial antiretroviral therapy (ART) and associated factors in Guangxi Zhuang autonomous region. Methods: This retrospective cohort study was conducted in HIV-infected children under initial ART in Guangxi from 2004 to 2019, data from ART information system of National comprehensive AIDS prevention and treatment information system. Cox proportional hazards models were used to assess factors associated with the death and attrition. Results: In 943 HIV-infected children, the overall mortality and attrition rates were 1.00/100 person-years and 0.77/100 person-years, respectively. The mortality and attrition rates within the first year of ART were 3.90/100 person-years and 1.67/100 person-years, respectively. The cumulative survival rate during the first, second, fifth and tenth year after ART was 96.14%, 95.80%, 93.68% and 91.54%, respectively. Multivariate Cox proportional hazards models results showed that being female (aHR=2.00, 95%CI: 1.17-3.40), CD4⁺T lymphocytes (CD4) counts before ART <200 cells/μl (aHR=2.79, 95%CI: 1.54-5.06), weight-for-age Z score before ART <-2 (aHR=2.38, 95%CI: 1.32-4.26), hemoglobin before ART <80 g/L (aHR=2.47, 95%CI: 1.24-4.92), initial ART with LPV/r (aHR=5.05, 95%CI: 1.15-22.12) were significantly associated with death; being female (aHR=2.23, 95%CI: 1.22-4.07) and initial ART with LPV/r (aHR=2.02, 95%CI: 1.07-3.79) were significantly associated with attrition. Conclusions: The effect of ART in HIV-infected children in Guangxi was better, but the mortality and attrition rates were high within the first year of treatment. It is necessary to strengthen the training in medical staff and health education in HIV-infected children and their parents in order to improve the treatment effect.
