Objective To analyze the clinical efficacy,safety and influencing factors of decitabine (DAC)-based regimens in patients with myelodysplastic syndrome-refractory anemia with excess blasts (MDS-RAEB).Methods We performed a retrospective analysis of 63 patients with MDS-RAEB treated with DAC,evaluated the clinical efficacy and adverse reactions,and analyzed the influencing factors affecting survival.Results Among 63 patients,23 were RAEB-1 and 40 were RAEB-2.The median treatment was 4 (2-13) courses.The total effective rate of DAC for MDS-RAEB was 58.7％ (37/63),and the complete response rate was 20.6％ (13/63).Among 37 patients who were effective,20 (54.1％) patients performed efficacy after 2 courses.The median course of treatment to achieve the best effect was 3.5 (3-4) courses.With a median follow-up of 14 (2-68) months,63 patients had a overall survival rate (OS) of 84.2％ and a 1-year progression-free survival rate (PFS) of 73％.In univariate analysis,the factors that prolonged OS were that the best effect after medication was stable disease (SD) (to achieve complete remission,partial remission,complete bone marrow remission,hematological improvement) (P =0.009) and no thrombocytopenia at first diagnosis (P =0.019),the factor that prolongs PFS is the best effect above SD (P =0.003).Multivariate analysis suggested that the factors affecting OS and PFS were the best curative effects above SD (P =0.015 vs P =0.008).The adverse effects of decitabine in the treatment of MDSRAEB were mainly bone marrow suppression and pulmonary infection.Conclusions Decitabine is an effective and well-tolerated drug in the treatment of MDS-RAEB.Response to decitabine treatment is one of the independent factors affecting the prognosis.

Objective:To explore the clinical features, treatment, prognosis and genetic mutation in neonatal congenital hyperinsulinemia(CHI).Methods:Neonates with CHI admitted to the neonatal intensive care unit of Hebei Provincial Children′s Hospital from February 2017 to August 2020 were selected, and their clinical characteristics, diagnosis and treatment, prognosis and genetic mutation were retrospectively analyzed.Results:A total of seven neonates were enrolled.The average gestational age was(38.1±1.5)weeks with two cases gestational age<37 weeks.The mean birth weight was(3 608±906)g with three cases birth weight>4 000 g. The common clinical manifestations included lethargy, poor feeding, cyanosis, seizures, and tremble.Non-specific manifestations were observed in two premature infants, whose blood glucose were found very low during the routine monitoring at 1 hour and 3 hours after birth respectively.Among the seven cases, six cases needed high glucose infusion rate(GIR)[>10 mg/(kg·min)] to maintain the serum glucose at the normal level from the beginning.Only one case needed lower GIR[3-5 mg/(kg·min)] on admission while gradually increased to 8 mg/(kg·min) maximumly during hospitalization.All seven neonates were treated with diazoxide orally, and two cases(2/7) were effective, including one case who discontinued the drug at six months after birth with normal blood glucose level.The remaining five neonates(5/7) were diazoxide resistant due to mutations in the ABCC8 gene encoding the K ATP+ -channel of the pancreatic beta cell and then treated with octreotide.Two cases(2/5) of them were effective to octreotide and the other three cases(3/5) were both diazoxide and octreotide resistant.One case died after withdrawal from the treatment and the other one lost follow-up.The other five cases were followed up until now.Normal neurological development were found in three cases.Two cases were found with epilepsy and moderate developmental delay in language and social competence ability during the follow up.Mutations in ABCC8 were the most common in seven cases, of which six cases were heterozygous mutation of ABCC8 and one case was heterozygous mutation of GLUDI. Conclusion:The clinical manifestations of CHI are non-specific.The blood glucose level of the high-risk neonates should be timely monitored.Neonates who needs lower GIR[<8 mg/(kg·min)] at the early stage can not be completely excluded CHI.Some CHI cases may self-resolved after several months.Molecular diagnosis can identify the pathogenic genes, which is important to achieve accurate diagnosis and treatment, and thus improve the prognosis of patients with CHI.

Objective:To analyze the demands of contracted family doctor service among uncontracted young and middle-aged people in Shanghai Baoshan.Methods:An online questionnaire survey on demands of contracted family doctor service was conducted in June 2021 among 702 uncontracted residents aged 18-60 years from Shanghai Baoshan district selected by stratified random sampling method. The demands of contracted family doctor service, including digital health file, routine laboratory tests and imaging investigation;health promotion;service convenience; home service were surveyed, and the factors related the demands were analyzed with regression analysis.Results:The survey showed that the demands of service convenience (3.8(3.0, 5.0)) and home service (4.0(3.0, 5.0)) were higher, while those of digital health file (3.0(2.0, 5.0)) and health promotion (3.0(2.0, 5.0)) were relatively lower. There were significant differences in the demands of all five contracted services among residents with different gender, age, education level, household register and family income (all P<0.05); while for young residents with different types of medical insurance there was significant difference in demands of all contracted services except digital health file (all P<0.05). Logistic regression analysis indicated that female( OR=1.83, P<0.001), high educational level( OR=4.81, P=0.019), household registered in Shanghai( OR=1.80, P=0.004)had higher demand for service convenience; female gender( OR=1.68, P=0.001), high educational level( OR=4.56, P=0.023)had higher demand for home service demands. Conclusion:The demands for contracted family doctor services are different among the uncontracted young and middle-aged people in Baoshan district, while the service convenience is generally most demanded. The study indicates that the contracted family doctor service should be provided accordingly.

Objective To investigate the efficacy of domestic porcine antihuman lymphocyte immunoglobulin (p-ALG) in the treatment of severe aplastic anemia (SAA) with allogeneic hemopoietic stem cell transplantation (HSCT). Methods The clinical data of 5 SAA patients who received allogeneic HSCT from January 2015 to May 2018 were retrospectively analyzed. The conditioning regimen included p-ALG + cyclophosphamide + fludarabine. The method of peripheral stem cell and bone marrow blood was used in allogeneic HSCT (the total amount of bone marrow blood was less than 400 ml and the puncture point was not replaced). The p-ALG related complications, post-transplantation hemopoietic stem cell reconstitution time and efficacy were recorded. Results Allergic reaction occurred in 1 patient when using p-ALG, and there was no serum reaction. Hemopoietic reconstitution was achieved in all the 5 patients. The time for neutrophilic granulocyte > 0.5 × 109/L was 11 to 17 d, and the time for platelet count > 20 × 109/L was 11 to 15 d after transplantation. The results of short-strand repeat polymerase chain reaction assays showed all complete donor chimera. Graft versus host disease occurred in 3 cases, and was successfully controlled by methylprednisolone and tacrolimus. The time for stopping red blood cell transfusion was 9 to 87 d. The patients were followed up for 1 to 37 months, and the patients all survived well. Conclusions The efficacy of p-ALG in SAA patients of allogeneic HSCT is affirmative, and the cost is obviously reduced. It is worthy of clinical use.

Background Acute drug poisonings are increasing year by year and have become the leading cause of acute poisoning in Shanghai in recent years, and the related prevention and control work is faced with a tough situation. Objective To understand the composition of drugs leading to acute poisonings and describe the epidemiological tendency of reported acute drug poisonings in Shanghai. Methods We collected registered acute drug poisoning case information from the Shanghai Health Information System under Shanghai Health Statistics Center, including demographic characteristics and clinical diagnosis. There were totally 86476 cases reported from 2019 to 2021. The distributions of drugs and victims were described by year. Incidence tendency of acute drug poisonings was analyzed by chi-square test and the analysis focused on analgesic, hypnotics, and antidepressant drug-associated poisonings. Spatial autocorrelation analysis was performed by GeoDa1.20 through calculating global and local Moran's I. Results There was an ascendant tendency in both case count (22132 cases in 2019, 29071 cases in 2020, and 35273 cases in 2021) and crude morbidity (0.89‰ in 2019, 1.21‰ in 2020, and 1.46‰ in 2021) of patients who received outpatient service or emergency treatment for acute drug poisonings from 2019 to 2021 in Shanghai. The top 3 kinds of acute poisoning drugs were analgesics, hypnotics, and antidepressants. The morbidity rates of acute drug poisonings associated with antidepressants (χ²=2700.15, P<0.05) and analgesics (χ²=2294.01, P<0.05) increased year by year. The leading 3 kinds of drugs associated with acute drug poisonings in the same age group were similar. Analgesics showed high frequency staying in the top 3 acute poisoning drugs in most age groups for the 3 years (the highest morbidity was 0.84‰ in male or 1.07‰ in female). Antidepressants were in the top 3 acute poisoning drugs in the under 59 years age groups for the 3 years (male morbidity rate was 0.12‰-0.44‰, and female morbidity rate was 0.06‰-0.45‰). Hypnotics were in the top 3 acute poisoning drugs in the ≥ 18 years age groups for the 3 years (morbidity rate in male was 0.28‰-0.98‰, and morbidity rate in female was 0.21‰-0.92‰). Cardiovascular drugs were in the top 3 acute poisoning drugs in the > 60 years age group for the 3 years (male morbidity rate was 0.40‰-1.03‰, and female morbidity rate was 0.66‰-0.81‰). Regarding the causes of poisonings, accidental poisoning and exposure was the main cause in the ≤ 17 years groups (male constituent ratio was 57.64%-67.12%, and female constituent ratio was 55.27%-68.27%); suicide (male constituent ratio was 20.28%-43.51%, and female constituent ratio was 25.18%-52.02%) had a higher percentage than accidental poisoning and exposure (male constituent ratio was 16.97%-23.62%, and female constituent ratio was 12.76%-17.63%) in the 18-59 years age groups; accidental poisoning and exposure (male constituent ratio was 24.38%-45.18%, and female constituent ratio was 32.69%-38.11%) had a higher percentage than suicide (male constituent ratio was 12.35%-14.02%, and female constituent ratio was 11.92%-12.31%) in the > 60 years age group. The spatial autocorrelation analysis showed that the distribution of acute poisoning cases caused by analgesics, hypnotics, or antidepressants was not random. It was mostly positive spatial clustering. The high-morbidity area was always in the outer-ring circle, especially in Xuhui, Changning, and Jing'an districts, which suggested a high-high cluster pattern. Conclusion In view of the increasing morbidity rate of acute drug poisoning cases in Shanghai in this study, it is urgent to take prevention and control actions. We should plan further studies and different strategies toward different victims with distinct drug poisoning characteristics and areas with high morbidity rates.

Objective:To detect the abnormal changes of myocardial blood perfusion in patients with hypertrophic cardiomyopathy(HCM) by myocardial contrast echocardiography (MCE) combined with adenosine stress test.Methods:Fifteen adult patients with HCM who were treated in Fuwai Central China Cardiovascular Hospital from May 2021 to March 2022 were prospectively selected as the HCM group, and eighteen healthy volunteers matched by gender, age and body surface area during the same period were chosen as the control group. All subjects underwent routine echocardiography, rest and adenosine stress MCE. The MCE images were analyzed by QLab software to obtain the myocardial perfusion parameters: peak signal intensity (A value), rising slope of the curve (β value) and A×β value, and the differences of above parameters between the two groups were compared.According to whether the end-diastolic wall thickness ≥12 mm, the myocardial segments in the HCM group were divided into hypertrophic segments and non-hypertrophic segments. The differences in myocardial perfusion parameters were compared among control group segments, hypertrophic segments and non-hypertrophic segments of the HCM group. The correlations of stress myocardial blood flow with maximal left ventricular wall thickness (MLVWT), left ventricular mass index (LVMI) and left atrial volume index (LAVI) in the HCM group were analyzed.Results:Compared with the control group, the A value, β value and A×β value of whole myocardium, hypertrophic segments and non-hypertrophic segments in the HCM group were significantly decreased in the rest and adenosine stress state, and the differences were statistically significant (all P<0.05). In the stress state, the A value, β value and A×β value of the hypertrophic segments were significantly lower than those in the non-hypertrophic segments in the HCM group, and the detection rate of abnormal perfusion segments in the HCM group was significantly higher than that in the rest state(all P<0.05). Compared with the control group, the myocardial blood flow reserve of whole myocardium, hypertrophic segments and non-hypertrophic segments in the HCM group were significantly decreased, and the differences were statistically significant(all P<0.05). The stress myocardial blood flow in the HCM group was negatively correlated with MLVWT, LVMI and LAVI ( r=-0.815, -0.805, -0.742; all P<0.05). Conclusions:Myocardial blood perfusion abnormalities can occur in both hypertrophic and non-hypertrophic myocardial segments in patients with HCM, and adenosine stress MCE can significantly improve the sensitivity of detecting myocardial perfusion abnormalities. The stress myocardial blood flow in patients with HCM is negatively correlated with MLVWT, LVMI and LAVI.
