Objective:To summarize the clinical characteristics of patients with end-stage heart failure who receive heart transplant under extracorporeal membrane oxygenation (ECMO) support.Methods:The clinical data of 12 pediatric patients who received heart transplant with ECMO support in the Seventh Medical Center of Chinese People′s Liberation Army General Hospital and Guangdong Provincial People′s Hospital, from January 2019 to December 2023 was collected. The data included sex, age, weight, diagnosis, pre-ECMO lactate level, left ventricular ejection fraction (LVEF), vasoactive-inotropic score (VIS), and preoperative ECMO running time. Surgical data included cold ischemia time of the donor heart, cardiopulmonary bypass time, intraoperative use of immunosuppressant, postoperative use of ECMO, duration of postoperative ECMO, rate of successful weaning from ECMO, and survival discharge rate. The paired t-test was performed to compare cardiac function indices before and after left ventricular decompression. Results:The 12 patients ranged in age from 1.1 to 15.8 years, and weighted from 8 to 63 kg. Ten children were diagnosed with dilated cardiomyopathy, one with myocardial underdensification, and one with a novel heterozygous mutation of the SCN5A gene causing overlap syndrome complicated by fatal arrhythmia. Before ECMO, the lactate ranged from 0.6 to>15.0 mmol/L, the LVEF from 6.5% to 43%, and VIS from 3 to 108. Four patients underwent left ventricular decompression supported by preoperative ECMO, and their pulse pressure was significantly increased after decompression ((17.8±2.1) vs. (9.8±1.5) mmHg, 1 mmHg=0.133 kPa, t=11.31, P=0.001), while there was no apparent change in LVEF ((26.8±4.4)% vs. (24.9±4.9)%, t=1.75, P=0.178). A total of 7 children received a second run of ECMO after surgery and 3 of them successfully weaned off ECMO and survived to discharge. In the entire cohort, 10 were successfully weaned from ECMO and 8 survived to discharge. Conclusions:For children with end-stage heart failure supported by ECMO, left ventricular decompression can significantly improve pulse pressure. These patients will eventually require heart transplantation.

OBJECTIVE
To establish a method for the determination of the concentrations of anti-tumor lead compounds purine benzamides PLB-E and PLB-P in rat plasma by HPLC and apply to study pharmacokinetics.
METHODS
The established HPLC was used to determine the plasma drug concentrations of rats at different time points after intravenous administration of 5, 10, 20 mg·kg–1 (low, medium, high doses) of PLB-E and PLB-P, and the pharmacokinetic parameters of each compound were calculated using DAS 3.3.0 software.
RESULTS
PLB-E and PLB-P had good linear relationship in the range of 2–120, 3–60 μg·mL–1, respectively(r2>0.999). The RSD of inter-day and intra-day precision were <15%. The extraction recoveries were 87.48%–92.84% and 88.24%–92.60%, respectively. The main pharmacokinetic parameters of PLB-E and PLB-P after a single intravenous injection of 5, 10, 20 mg·kg–1 were as follows, the average Cmax was (20.30±2.39), (40.63±3.40), (63.62±7.55)mg·L–1 and (13.21±1.40), (24.87±1.33), (32.83±0.65)mg·L–1, respectively. AUC(0-∞) were (104.67±48.39), (177.42±84.11), (194.32±91.48)mg·h·L–1 and (106.75±54.21), (179.90±93.59), (253.56±126.17)mg·h·L–1, respectively. Tmax of each dose was 0.08 h.
CONCLUSION
The HPLC method established in this study meets the requirements for the determination of biological samples through methodological verification, which is applicable to the determination of the concentration of PLB-E and PLB-P in rat plasma and the pharmacokinetic study. The pharmacokinetic process of PLB-E and PLB-P in rats conforms to the two-compartment model, and conforms to the nonlinear kinetic elimination.

Objective: To understand the status of autism spectrum disorder (ASD) cohort studies and explore the feasibility of constructing ASD disease-specific cohorts based on real-world data (RWD). Methods: ASD cohort studies published by December 2022 were collected by literature retrieval from major Chinese and English databases. And the characteristics of the cohort were summarized. Results: A total of 1 702 ASD cohort studies were included, and only 60 (3.53%) were from China. A total of 163 ASD-related cohorts were screened, of which 55.83% were birth cohorts, 28.22% were ASD-specific cohorts, and 4.91% were ASD high-risk cohorts. Most cohorts used RWD such as hospital registries or conducted community-based field surveys to obtain participant information and identified patients with ASD by scales or clinical diagnoses. The contents of the studies included ASD incidence and prognostic risk factors, ASD comorbidity patterns and the impact of ASD on self-health and their offspring's health. Conclusions: ASD cohort studies in developed countries have been in the advanced stage, while the Chinese studies are still in their infancy. RWD provides the data basis for ASD-specific cohort construction and offers new opportunities for research, but work such as case validation is still needed to ensure the scientific nature of cohort construction.

Angong Niuhuang Pills(AGNHP) are effective in clearing heat, removing the toxin, and eliminating phlegm for resuscitation. Clinically, it is widely used to treat various diseases such as febrile convulsion due to heat attacking pericardium, but its therapeutic effects on heart failure(HF) have not been well recognized. In this study, the profiles of differential metabolites regulated by AGNHP were identified by ultra-high performance liquid chromatography-quadrupole time-of-flight mass spectrometry(UPLC-Q-TOF-MS). The underlying mechanism of AGNHP against HF was illustrated based on the integrated analysis of pharmacological data and metabolic molecular network. The HF model was induced by isoproterenol in mice. After oral administration of AGNHP for one week, cardiac functions in HF mice were evaluated by echocardiography, and serum samples of mice were collected for metabolomics analysis. Eight differential metabolites of AGNHP against HF were screened out through partial least square discriminant analysis(PLS-DA) and input into MetaboAnalyst for the analysis of metabolic pathways. Moreover, the critical metabolic pathways regulated by AGNHP were enriched according to the potential targets of major compounds in AGNHP. After AGNHP treatment, the recovered index of relative content of some metabolites underwent cross-scale fusion analysis with therapeutic efficacy data, followed by "compound-reaction-enzyme-gene" network analysis. It is inferred that the anti-HF effects of AGNHP may be attributed to the metabolism of arachidonic acid, amino acid, glycerophospholipid, and linoleic acid. The cross-scale polypharmacological analysis method developed in this study provides a new method to interpret scientific principles of AGNHP against HF with modern technologies.

OBJECTIVE:
To investigate the clinical characteristics and treatment of pneumocystis carinii pneumonia (PCP) in children with acute lymphoblastic leukemia (ALL), in order to improve the early diagnosis and effective treatment.
METHODS:
Clinical data of five children with ALL developing PCP in the post-chemotherapy granulocyte deficiency phase were analyzed retrospectively. The clinical manifestations, laboratory tests, imaging findings, treatment methods and effect were summarized.
RESULTS:
The male-to-female ratio of the five children was 1∶4, and the median age was 5.5 (2.9-8) years old. All patients developed PCP during granulocyte deficiency phase after induction remission chemotherapy. The clinical manifestations were generally non-specific, including high fever, tachypnea, dyspnea, non-severe cough, and rare rales in two lungs (wet rales in two patients). Laboratory tests showed elevated C-reactive protein (CRP), serum procalcitonin (PCT), (1,3)-β-D-glucan (BDG), lactate dehydrogenase (LDH) and inflammatory factors including IL-2R, IL-6 and IL-8. Chest CT showed diffuse bilateral infiltrates with patchy hyperdense shadows. Pneumocystis carinii(PC) was detected in bronchoalveolar lavage fluid (BALF) or induced sputum by high-throughput sequencing in all patients. When PCP was suspected, chemotherapy was discontinued immediately, treatment of trimethoprim-sulfame thoxazole (TMP-SMX) combined with caspofungin against PC was started, and adjunctive methylprednisolone was used. Meanwhile, granulocyte-stimulating factor and gammaglobulin were given as the supportive treatment. All patients were transferred to PICU receiving mechanical ventilation due to respiratory distress during treatment. Four children were cured and one died.
CONCLUSION
PCP should be highly suspected in ALL children with high fever, dyspnea, increased LDH and BDG, and diffuse patchy hyperdense shadow or solid changes in lung CT. The pathogen detection of respiratory specimens should be improved as soon as possible. TMP/SMZ is the first-line drug against PCP, and the combination of Caspofungin and TMP/SMZ treatment for NH-PCP may have a better efficacy. Patients with moderate and severe NH-PCP may benefit from glucocorticoid.

Objective:To explore the effect of emergency "zero channel" process on improving the efficiency of intravenous thrombolysis in stroke.Methods:Fifty-eight acute ischemic stroke patients admitted to our hospital from January 2020 to December 2020 were enrolled into experimental group; another 58 acute ischemic stroke patients admitted to our hospital from January 2019 to December 2019 and matched with age and gender were selected as control group. "Green channel" process was adopted for patients in the control group, and optimized "zero channel" process (moving the working passageway forward to the ambulance) was implemented for patients in the experimental group. Door to rescue room time (DRRT), door to consultation time (DCT), door to laboratory examination completion time (DLECT), door to CT report time (DCRT), and door to needle time (DNT) were used to evaluate the times of emergency treatment. The thrombolytic effect of the two groups was compared by evaluating the recanalization rate of occluded vessels and thrombolytic efficiency. Modified Rankin scale (mRS) was used to evaluate the prognoses 6 months after treatment in both groups, and mRS scores≤2 was defined as good prognosis.Results:The DCRT, DCT and DNT in the experimental group were significantly shorter than those in the control group ( P<0.05); the compliance rate of DNT≤60 min in the experimental group was significantly higher as compared with that in the control group ( P<0.05). The immediate recanalization rate of occluded vessels in the experimental group and control group was 60.3% and 27.6%, and the thrombolytic efficiency was94.83% and 82.76%; significant differences were noted between the two groups ( χ2=12.633, P<0.001; χ2=4.245, P=0.039). The good prognosis rate of the experimental group and control group was 36.2% and 15.5%, respectively, after 6 months of follow-up ( χ2=4.016, P=0.041). Conclusion:Emergency "zero channel" can further shorten DCT, DCRT, and DNT, and improve the efficiency of thrombolysis and prognoses of acute ischemic stroke patients.

BACKGROUND:
There were few studies on real-world data about autologous hematopoietic stem cell transplantation (auto-HSCT) or allogeneic HSCT (allo-HSCT) in peripheral T-cell lymphoma (PTCL). This study aimed to investigate the clinical outcomes of patients who received auto-HSCT or allo-HSCT in China.
METHODS:
From July 2007 to June 2017, a total of 128 patients who received auto-HSCT (n = 72) or allo-HSCT (n = 56) at eight medical centers across China were included in this study. We retrospectively collected their demographic and clinical data and compared the clinical outcomes between groups.
RESULTS:
Patients receiving allo-HSCT were more likely to be diagnosed with stage III or IV disease (95% vs. 82%, P = 0.027), bone marrow involvement (42% vs. 15%, P = 0.001), chemotherapy-resistant disease (41% vs. 8%, P = 0.001), and progression disease (32% vs. 4%, P < 0.001) at transplantation than those receiving auto-HSCT. With a median follow-up of 30 (2-143) months, 3-year overall survival (OS) and progression-free survival (PFS) in the auto-HSCT group were 70%(48/63) and 59%(42/63), respectively. Three-year OS and PFS for allo-HSCT recipients were 46%(27/54) and 44%(29/54), respectively. There was no difference in relapse rate (34%[17/63] in auto-HSCT vs. 29%[15/54] in allo-HSCT, P = 0.840). Three-year non-relapse mortality rate in auto-HSCT recipients was 6%(4/63) compared with 27%(14/54) for allo-HSCT recipients (P = 0.004). Subanalyses showed that patients with lower prognostic index scores for PTCL (PIT) who received auto-HSCT in an upfront setting had a better outcome than patients with higher PIT scores (3-year OS: 85% vs. 40%, P = 0.003). Patients with complete remission (CR) undergoing auto-HSCT had better survival (3-year OS: 88% vs. 48% in allo-HSCT, P = 0.008). For patients beyond CR, the outcome of patients who received allo-HSCT was similar to that in the atuo-HSCT group (3-year OS: 51% vs. 46%, P = 0.300).
CONCLUSIONS
Our study provided real-world data about auto-HSCT and allo-HSCT in China. Auto-HSCT seemed to be associated with better survival for patients in good condition (lower PIT score and/or better disease control). For patients possessing unfavorable characteristics, the survival of patients receiving allo-HSCT group was similar to that in the auto-HSCT group.

Objective:
We aimed to investigate and interpret the associations between socioeconomic factors and the prevalence, awareness, treatment, and control of hypertension at the provincial level in China.
Methods:
A nationally and provincially representative sample of 179,059 adults from the China Chronic Disease and Nutrition Surveillance study in 2015-2016 was used to estimate hypertension burden. The spatial Durbin error model was fitted to investigate socioeconomic factors associated with hypertension indicators.
Results:
Overall, it was estimated that 29.20% of the participants were hypertensive nationwide, among whom, 34.32% were aware of their condition, 27.69% had received antihypertensive treatment, and 7.81% had controlled their condition. Per capita gross domestic product (GDP) was associated with hypertension prevalence (coefficient: -2.95, 95%
Conclusion
Hypertension indicators were not only directly influenced by socioeconomic factors of local area but also indirectly affected by characteristics of geographical neighbors. Population-level strategies should involve optimizing supportive socioeconomic environment by integrating clinical care and public health services to decrease hypertension burden.
