METHODS Retrieved from CNKI， VIP， Wanfang， CBM， Cochrane Library and PubMed， randomized controlled trials （RCTs） about Jianwei xiaoshi oral liquid in the treatment of FD in children were collected from the inception to Apr. 2024. The control group was treated with conventional western drugs （including gastrointestinal motion-promoting， antacids or acid-suppressing drugs）， and the trial group was treated with Jianwei xiaoshi oral liquid alone or combined with conventional Western drugs （drug dosage and course of treatment were the same as the control group）. Meta-analysis was performed using RevMan 5.3 software after quality evaluation with the Cochrane risk bias assessment tool 6.1. RESULTS Totally 16 literature were employed which included 1 962 patients. The results of meta-analysis showed that the total clinical effective rate of Jianwei xiaoxi oral liquid in the treatment of FD in children of trial group was significantly higher than that of the control group [RR＝1.18， 95%CI （1.13， 1.22）， P＜0.000 01]. In this study， subgroup analysis was conducted on the usage and dosage， course of treatment， and combination or not in trial group， as well as the type of conventional Western drugs. The results showed that the total clinical effective rate of trial group was significantly higher than that of control group； the relief time of abdominal distension and abdominal pain in trial group [MD＝－2.54， 95%CI （－3.10， －1.98）]， loss of appetite relief time [MD＝－2.12， 95%CI （－2.63， －1.61）]， nausea and vomiting relief time [MD＝－1.70， 95%CI （－2.27， －1.14）]， and belching relief time [MD＝－1.61， 95%CI （－2.44， －0.78）] were shorter than that of the control group significantly （P＜0.05）. In addition， compared with control group， the levels of gastrin [SMD＝1.63， 95%CI （0.98， 2.29）] and motilin [SMD＝2.06， 95%CI （1.58， 2.54）] as well as gastric antral emptying rate [MD＝5.99， 95%CI （2.78， 9.21）] in trial group were increased significantly， while the level of somatostatin was decreased significantly [SMD＝－1.30， 95%CI （－1.57， －1.02）] （P≤0.000 3）. CONCLUSIONS Jianwei xiaoshi oral liquid， whether used alone or in combination with other medications， and regardless of the treatment course or dosage and usage， is effective in treating FD in children， with good safety.

This research established a simple, rapid and sensitive ultra-high-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF-MS/MS) method to investigate the metabolic profiles of cajanonic acid A (CAA) in rats. After intragastric administration of CAA (30 mg·kg^-1) to rats, the biological samples were detected by UPLC-Q-TOF-MS/MS. Relevant data was collected and processed, the accurate mass and MS² spectra of the metabolites were compared with the parent compound. As a result, a total of 23 metabolites were detected, including 15 in urine, 11 in bile, 11 in feces, and 9 in plasma. The major metabolic pathways related to CAA included dehydrogenation, reduction, hydroxylation, methylation and glucuronide conjugation. This experiment was approved by Animal Ethics Committee of Guizhou Medical University (approval number: 1603137).

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 analyze the prognostic value of del(1p32)in patients with newly diagnosed multiple myeloma(MM).Methods:The clinical data of 341 newly diagnosed MM attended in Jiangsu Province Hospital were retrospective analyzed.Clinical characteristic combined with genetic features,especially del(1p32),were analyzed for survival and prognostic of patients.Results:Among the 341 patients with newly diagnosed MM,24(7.0％)patients were del(1p32)positive.The progression-free survival(PFS)and overall survival(OS)were significantly shorter in MM patients with del(1p3 2)than those without de1(1p32)(PFS:P＜0.001;OS:P＜0.001).The COX proportional-hazards model showed that del(1 p32)was an independent risk factor for PFS and OS of patients with MM.The patients with both 1q21 gain/amplification and del(1p32),as"double-hit chromosome 1",have worse prognosis than those with only 1q21 gain/amplification or only del(1 p32)(PFS:P＜0.001;OS:P＜0.001).Conclusion:Del(1p32)is an independent risk factor for PFS and OS of patients with MM.Del(1p32)detection should be widely used in the prognostic analysis for newly diagnosed MM patients.

Objective:To investigate the mechanism of DNA damage and repair in MLL-rearranged acute myeloid leukemia(MLL-r AML)cells by the combination of Chidamide and the BRD4 inhibitor(+)-JQ-1.Methods:MLL-r AML cell lines Molm-13,MV4-11 and non-MLL-r AML cell line Kasumi were divided into control group(contr),Chidamide group(chida),(+)-JQ-1 group and Combination group(combi),respectively.Cell viability of Molm-13 was measured by CCK-8 to determine optimal the concentrations of Chidamide and(+)-JQ-1.The cell cycle was detected by flow cytometry,and apoptosis-related factors Bcl-2,Bax and caspase-3 were detected by Western blot.DNA damage marker γH2AX was detected by immunofluorescence.The protein expressions of DNA damage factor γH2AX,DNA damage checkpoint kinases p-ATR,p-CHK1,p-ATM,p-CHK2 and DNA damage repair factors Rad51 and 53BP1 were detected by Western blot.The expression of DNA damage repair factors Rad51 and 53BP1 mRNA was detected by qRT-PCR.Results:Under the treatment of Chidamide(300 nmol/L)and(+)-JQ-1(400 nmol/L),the proportion of G1 phase cells in MLL-r AML cell lines Molm-13 and MV4-11 was increased in combination group compared with control group.In non-MLL-r AML cell line Kasumi,compared with control group,the proportion of G1 phase cells in combination group was increased(P＜0.05).In Molm-13 and MV4-11 cell lines,compared with control group,the expression level of DNA damage marker γH2AX in combination group was increased(P＜0.05).The expression levels of DNA damage checkpoint and damage repair factors p-ATR,p-CHK1,p-ATM,p-CHK2,Rad51,53BP1 were decreased(P＜0.05).In Kasumi cell line,compared with control group,there was no significant change in the expression of some of the above factors in combination group(P＞0.05),but the expression trend of some factors was opposite.In MLL-r AML cell lines Molm-13 and MV4-11,compared with control group,the expression levels of Bax and caspase-3 protein were increased in combination group,while the expression levels of Bcl-2 protein were decreased(P＜0.05).In non-MLL-r AML cell line Kasumi,there was no significant change in apoptotic factor protein expression in combination group compared with control group(P＞0.05).Conclusion:Chidamide combined with(+)-JQ-1 can inhibit the proliferation of MLL-r AML cells,inhibit the initiation of protective self-repair of these leukemia cells by inhibiting the DNA damage response pathway,and ultimately increase the apoptosis of these cells,but non-MLL-r AML cells have no similar results.

Objective To explore the association between R611H(G/A,rs734312)variation of WFS1 gene and early-onset type 2 diabetes mellitus(T2DM).Methods A total of 181 Chinese patients with early-onset T2DM(T2DM group)and 196 non-diabetic controls(NC group)were enrolled in this study.The rs734312 variation was detected by PCR-direct sequencing.Genotypic and allelic frequencies of rs734312 and clinical variables were compared and analyzed between the two groups.Results Compared with the NC group,the frequencies of AA genotype and A allele in R611H(G→A)variation were significantly elevated in the early-onset T2DM group,AA vs GA+GG(OR 1.720,95%CI 1.100～2.680,P<0.05).A vs G(OR 1.500,95%CI 1.020～2.220,P<0.05).The remarkable differences of frequencies of genotype and allele in rs734312(G/A)were observed between Asians(China,Japan and Korea)and Caucasians(Denmark,Britain,Spain,France and Russia,P<0.01 for each).Compared with AA genotype,fasting and 2 hours postprandial insulin(FIns and 2 hIns)as well as HOMA-β were significantly rise in GG+GA genotype carriers of early-onset T2DM group(P<0.05).Conclusions The a allele of rs734312 in WFS1 may be a risk factor for early-onset T2DM in Chinese population,and the variation might be a potential genetic marker for predicting the islet β-cell dysfunction in early-onset T2DM in Chinese population.

The male patient,one day old,was admitted to the hospital due to hypoglycemia accompanied by apnea appearing six hours after birth.The patient had transient hypoglycemia early after birth,and acute heart failure suddenly occurred on the eighth day after birth.Laboratory tests showed significantly reduced levels of adrenocorticotropic hormone and cortisol,and pituitary magnetic resonance imaging was normal.Genetic testing results showed that the patient had probably pathogenic compound heterozygous mutations of the TBX19 gene(c.917-2A＞G+c.608C＞T),inherited respectively from the parents.The patient was conclusively diagnosed with congenital isolated adrenocorticotropic hormone deficiency caused by mutation of the TBX19 gene.Upon initiating hydrocortisone replacement therapy,cardiac function rapidly returned to normal.After being discharged,the patient continued with the hydrocortisone replacement therapy.By the 18-month follow-up,the patient was growing and developing well.In neonates,unexplained acute heart failure requires caution for possible endocrine hereditary metabolic diseases,and timely cortisol testing and genetic testing should be conducted.[Chinese Journal of Contemporary Pediatrics,2024,26(3):321-324,V]

Objective To investigate the incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.
