Objective To report the clinical and imaging characteristics of a case with the clinical manifestation of multiple lung and liver nodules,diagnosed as IgG4-related hepatic inflammatory pseudotumor(HIPT)complicated by hepatic tissue-infection,and review the literature in order to facilitate clinical diagnosis and differential identification of IgG4-related HIPT.Methods A retrospective analysis was conducted on the medical records of a patient with IgG4-related disease(IgG4-RD)characterized by multiple lung and liver nodules.A literature review was performed by searching Chinese and English databases to summarize the clinical and imaging characteristics of IgG4-related HIPT and hepatic tissue infection.Results The case involved a 64-year-old female admitted to the Rheumatology and Immunology Department of the First Medical Center of Chinese PLA General Hospital due to"poor appetite and fatigue for over a year,and dry cough for four months".She presented with multiple nodules in the lungs and liver,without involvement of the eyelids,salivary glands,submandibular glands,or pancreas.Laboratory test results revealed elevated serum IgG4 levels at 14.1 g/L and C-reactive protein(CRP)at 82.1 mg/L.Pulmonary CT scans indicated multiple solid nodules in both lungs with clear boundaries.Abdominal contrast-enhanced MRI revealed a nodule in liver segment S7 with a pseudocapsule around it,clear boundaries,and uniform enhancement;another nodule in liver segment S5 with blurred boundaries and ring enhancement.The final diagnosis of the liver nodules was confirmed by pathological and metagenomic sequencing to be an IgG4-related HIPT in segment S7 and hepatic tissue infection in segment S5.After a full course of anti-infection and treatment with methylprednisolone and leflunomide,follow-up imaging showed near-complete resolution of the lung and liver nodules.Literatures were searched in China National Knowledge Infrastructure(CNKI),Wanfang,and PubMed databases(up to September 2023),and no case of IgG4-RD complicated with both liver involvement and infection was found.A total of 26 cases of IgG4-RD involving the liver have been reported so far,predominantly in males(92.3%),with an average age of 51 years.Most patients presented with abnormal liver function as the initial symptom,with normal blood inflammatory markers.Imaging typically shows a single nodule in 88.5%of cases,with clear boundaries and uniform enhancement,as well as ring enhancement.Concurrent involvement of the pancreas and biliary tract is common.Pathology is the gold standard for confirming the disease.Conclusions This case reports coexistence of IgG4-related HIPT and infection within multiple hepatic nodules.In the diagnosis and treatment of patients with IgG4-RD presenting with multiple hepatic nodules,if the imaging characteristics of the nodules are inconsistent,it is necessary to consider the possibility of the underlying disease coexisting with other conditions,which can be easily misdiagnosed.Actively obtaining pathological tissue is crucial for aiding in the definitive diagnosis.

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.

Abstract Allergic diseases can occur in all systems of the body, covering the whole life cycle, from children to adults and to old age, can be lifelong onset and even fatal in severe cases. Children account for the largest proportion of the victims of allergic disease, Children s allergies start from scratch, ranging from mild to severe, from less to more, from single to multiple systems and systemic performance, so the prevention and treatment of allergic diseases in children is of great importance, which can not only prevent high risk allergic conditions from developing into allergic diseases, but also further block the process of allergy. At present, there is no consensus on the management system of allergic children in kindergartens and primary schools. The "Consensus on Allergy Management and Prevention in Kindergartens and Primary Schools", which includes the organizational structure, system construction and management of allergic children, provides evidence informed recommendations for the long term comprehensive management of allergic children in kindergartens and primary schools, and provides a basis for the establishment of the prevention system for allergic children.

An open reading frame (ORF) of isopentenyl-diphosphate delta isomerase gene (FuIPI) was cloned from Fritillaria unibracteata Hsiao et K. C. Hsia. (F. unibracteata). Furthermore, the bioinformatics and functional analyses of FuIPI were performed in this study. The result showed that, the ORF of FuIPI gene was 825 bp, encoding a polypeptide of 274 amino acids in length, with a relative molecular mass of about 31 kD and a theoretical isoelectric point of 5.61. Sequence analysis showed that FuIPI contained conserved structural domains and key residues involved in the catalyzing process. The phylogenetic analysis exhibited that FuIPI was closely related to IPIs of Dendrobium officinale and Musa acuminate. Real-time PCR analysis showed that FuIPI was distributed in different tissues of F. unibracteata, but had the highest transcriptional level in leaves, followed by stems, bulbs, and flowers. Furthermore, the FuIPI protein was successfully expressed in Escherichia coli BL21(DE3). The purified FuIPI protein successfully catalyzed the conversion from isopentenyl diphosphate (IPP) to dimethylallyl pyrophosphate (DMAPP). The above results provided a theoretical basis for further investigation of the molecular role of FuIPI in the biosynthesis of alkaloids.

Objective: To evaluate the feasibility of identification and preservation of arm lymphatics (DEPART) in axillary lymph node dissection (ALND) for breast cancer to prevent arm lymphedema. Methods: A randomized controlled study method was used. Two hundred and sixty-five patients who underwent breast cancer surgery at the Department of Thyroid and Breast Surgery, Zhongnan Hospital of Wuhan University from November 2017 to June 2018 were included, and the patients were randomly divided into ALND+ DEPART group (132 patients) and standard ALND group (133 patients) by random number table method. In the ALND+ DEPART group, indocyanine green and methylene blue were injected as tracers before surgery, and the arm sentinel nodes was visualized by staged tracing during intraoperative dissection of axillary lymph nodes. Partial frozen sections were made of arm lymph nodes >1 cm in length and hard and suspicious of metastasis, and arm lymph nodes and lymphatic vessels were selectively preserved. Patients in the standard ALND group underwent standard ALND. Objective and subjective indexes of arm lymphedema were evaluated by 5-point circumference measurement and Norman questionnaire. Results: Among 132 breast cancer patients in the ALND+ DEPART group, 121 (91.7%) completed DEPART. There were no statistically significant differences in age, body mass index, pathological type, dissection number of axillary lymph node, N stage, TNM stage, molecular typing, and regional radiotherapy between the ALND+ DEPART and standard ALND groups (P>0.05). At a median follow-up of 24 months, assessment by the 5-point circumference measurement showed that the incidence rates of lymphedema in the ALND+ DEPART and standard ALND groups were 5.0% (6/121) and 15.8% (21/133), respectively, with statistically significant differences (P=0.005). Assessment by the Norman questionnaire showed that the incidence rates of lymphedema in the ALND+ DEPART and standard ALND groups were 5.8% (7/121) and 21.8% (29/133), respectively, with a statistically significant difference (P<0.001). No local regional recurrence was observed in either group during the follow-up period. Conclusion: For breast cancer patients with positive axillary lymph nodes, the administration of DEPART during ALND can reduce or avoid the occurrence of arm lymphedema without compromising oncology safety.

BACKGROUND: Postural tachycardia syndrome (POTS) is a common childhood disease that seriously affects the patient's physical and mental health. This study aimed to investigate whether pre-treatment baseline left ventricular ejection fraction (LVEF) and left ventricular fractional shortening (LVFS) values were associated with symptom improvement after metoprolol therapy for children and adolescents with POTS. METHODS: This retrospective study evaluated 51 children and adolescents with POTS who received metoprolol therapy at the Peking University First Hospital between November 2010 and July 2019. All patients had completed a standing test or basic head-up tilt test and cardiac echocardiography before treatment. Treatment response was evaluated 3 months after starting metoprolol therapy. The pre-treatment baseline LVEF and LVFS values were evaluated for correlations with decreases in the symptom score after treatment (ΔSS). Multivariable analysis was performed using factors with a P value of <0.100 in the univariate analyses and the demographic characteristics. RESULTS: A comparison of responders and non-responders revealed no significant differences in demographic, hemodynamic characteristics, and urine specific gravity (all P > 0.050). However, responders had significantly higher baseline LVEF (71.09% ± 4.44% vs. 67.17% ± 4.88%, t = -2.789, P = 0.008) and LVFS values (40.00 [38.00, 42.00]% vs. 36.79% ± 4.11%, Z = -2.542, P = 0.010) than the non-responders. The baseline LVEF and LVFS were positively correlated with ΔSS (r = 0.378, P = 0.006; r = 0.363, P = 0.009), respectively. Logistic regression analysis revealed that LVEF was independently associated with the response to metoprolol therapy in children and adolescents with POTS (odds ratio: 1.201, 95% confidence interval: 1.039-1.387, P = 0.013). CONCLUSIONS Pre-treatment baseline LVEF was associated with symptom improvement after metoprolol treatment for children and adolescents with POTS.

To systematically review the efficacy and safety of Naoxueshu Oral Liquid in treatment of hypertensive intracerebral hemorrhage, four Chinese databases, four English databases, clinical trials registration center(ClinicalTrials.gov) and Chinese clinical trial registry were retrieved. The retrieval time was from the establishment of each database to September 9, 2020. According to the set criteria, the randomized controlled trial(RCT) of Naoxueshu Oral Liquid combined with conventional Western medicine was selected. The "Cochrane bias risk assessment" tool was used to evaluate the quality of the included studies. RevMan 5.4.1 was used to conduct Meta-analysis of the included studies and GRADE system was used to evaluate the evidence quality of the outcome indicators. Eleven studies were finally included, with a total sample size of 1 221 cases, 612 cases in the treatment group and 609 cases in the control group. Meta-analysis showed that Naoxueshu Oral Liquid combined with conventional Western medicine had no significant difference compare with conventional Western medicine in reducing National Institute of health stroke scale(NIHSS) after 2 weeks of treatment for hypertensive intracerebral hemorrhage(MD=-1.59,95%CI[-3.46,0.29],P=0.10), but was superior to conventional Western medicine after 30 d of treatment(MD=-1.16,95%CI [-1.39,-0.94],P<0.000 01). Naoxueshu Oral Liquid combined with conventional Western medicine was superior to conventional Western medicine in improving Glasgow coma scale(MD=1.00,95%CI[0,2.00],P=0.05) and reducing the incidence of secondary brain insults(RR=0.38,95%CI[0.24,0.59],P<0.000 1), but there was no significant difference in increasing Barthel index(MD=1.00,95%CI[-0.30,2.30],P=0.13). In terms of effective rate, studies using Guideline for clinical trials of new patent Chinese medicines, NHISS or Glasgow outcome scale(GOS) had shown that Naoxueshu Oral Liquid combined with conventional Western medicine was superior to conventional Western medicine(RR_(Guideline for clinical trials of new patent Chinese medicines)=1.27,95%CI[1.10,1.46],P=0.001;RR_(NHISS)=1.26,95%CI[1.13,1.40],P<0.000 1;RR_(GOS)=1.54,95%CI[1.22,1.93],P=0.000 2). In reduction of hematoma volume, Naoxueshu Oral Liquid combined with conventional Western medicine was superior to conventional Western medicine after 2 and 4 weeks of treatment(MD_(2 week)=-2.31,95%CI[-3.12,-1.49],P<0.000 01;MD_(4 week)=-2.04,95%CI[-2.41,-1.68],P<0.000 01). GRADE system showed that the evidence level of the above outcome indicators was low and extremely low. In terms of adverse reactions, two of the included studies reported mild adverse reactions, and the rest of studies were not mentioned, so this study was not able to make a positive evaluation of the safety of Naoxueshu Oral Liquid. This study showed that compared with conventional Western medicine, combined Naoxueshu Oral Liquid may be better for hypertensive intracerebral hemorrhage. However, due to the high bias risk in the included studies, more large-sample and high-quality RCTs are still needed in the future.

Objective:Based on the previous animal experiments, to preliminarily explore the safety and efficacy of self-developed new smartphone-controlled vibrating capsule (VC) in the treatment of patients with functional constipation (FC).Methods:At the Outpatient Department of Gastroenterology, Changhai Hospital, Naval Medical University, 24 patients with FC were prospectively enrolled. The trial process included basic period for ≥two weeks, treatment period for six weeks, and follow-up visits ≥six (once every two weeks). During treatment period, the patients were assigned into sham capsule group, VC at low frequency mode group and VC at high frequency mode group and the patients swallowed 12 corresponding capsules. The safety of VC treatment was evaluated based on the observation the occurrence of adverse events (AE) in patients of three groups, which included abdominal pain, abdominal distention, capsule retention and abnormal laboratory indicators. The efficacy of VC treatment was assessed by comparison of the patients of three groups in mean complete spontaneous bowel movements (CSBM) per week, mean spontaneous bowel movements (SBM) per week, capsule discharge time, patient assessment of constipation quatity of life questionnaire (PAC-QOL), patient assessment of constipation symptom questionnaire (PAC-SYM). Chi-square test, least significant difference- t test, Kruskal-Wallis test, Wilcoxon rank sum test and Fisher exact test were used for statistical analysis. Results:Two patients were lost in follow up. In the end, seven, eight and seven patients were enrolled in sham capsule group, VC at low frequency mode group and VC at high frequency mode group. AE occurred in three patients. At the sixth week of treatment, the difference between average CSBM in one week and baseline of sham capsule group, VC at low frequency mode group and VC at high frequency mode group was 0.0 (0.0, 2.0), 2.0 (1.0, 2.8) and 1.0 (0.0, 5.0), respectively; and the difference between average SBM in one week and baseline of sham capsule group, VC at low frequency mode group and VC at high frequency mode group was -1.0 (2.0, 2.0), 1.0 (-0.8, 2.0) and 1.0 (0.0, 4.0), respectively. During the six weeks of treatment period, the difference between mean CSBM per week and baseline of three, seven and five patients of sham capsule group, VC at low frequency mode group and VC at high frequency mode group was more than one, and the difference between SBM per week and baseline of two, five and five patients was more than one. At the sixth week of treatment, capsule discharge time of VC at low frequency mode group and VC at high frequency mode group was shorter than that of sham capsule group ((65.7±9.3) and (59.1±3.4) h vs. (96.7±10.0) h), and during the whole treatment period capsule discharge time of VC at low frequency mode group and VC at high frequency mode group was shorter than that of sham capsule group ((63.6±8.6) and (59.8±6.6) h vs. (100.5±13.1) h), and the differences were statistically significant ( t=3.119, 3.584, 2.832 and 3.036, all P<0.05). The PAC-SYM score of patients of sham capsule group, VC at low frequency mode group and VC at high frequency mode group during the period of treatment was 14.3±2.0, 9.9±2.3 and 7.0±2.0, respectively, there were no statistically significant differences among the three groups ( P>0.05). The PAC-QOL score of patients of sham capsule group, VC at low frequency mode group and VC at high frequency mode group during the period of treatment was 31.3±4.4, 24.0±3.8 and 13.9±4.1, respectively, and the PAC-QOL score of VC at high frequency mode group was lower than that of sham capsule group, and the difference was statistically significant ( t=2.808, P=0.012), however, there was no statistically significant difference in the PAC-QOL score between VC at low frequency mode group and sham capsule group, and between VC at high frequency mode group and VC at low frequency mode group (both P>0.05). Conclusions:VC can be safely used in patients with FC, which can promote defecation and relieve the symptoms of constipation. However, there is no significant difference in the therapeutic effect of capsules with different vibration frequencies.
