Objective Hemapoietic stem cell (HSC) is a kind of pluripotent cell which can differentiate into different kinds of cells,including blood cells and immune cells.Hemapoietic stem cell transplantation(HSCT) is to destory abnormal bone marrow hematopoietic cells,and imbed healthy stem cells to reconstruct hematopoiesis and immune system,and it is an effective therapy for the treatment of hematopoietic malignances,genetic and metabolic disease,autoimmune disease and solid tumor.At present,it has been widely used to treat the patients with hematologial malignant tumors,such as lymphoma and leukemia.Clinical investigation showed that patients with leukemia and psoriasis after HSCT,both leukemia and psoriasis were cured.In this review,the immunopathogenesis of psoriasis,the possible mechanism of psoriasis associated with leukemia,the immunopathogenesis of HSCT and the theory basis of treating psoriasis and the application of HSCT in the treatment of psoriasis with leukemia were comprehensively discussed.

Uihgur medicine is not only an important component of medicine for ethnic minorities in China,but an vital supplement to modern medicine.With the development of modern science,in recent years good progerss has been made in basic sciences and applied research of Uighur medicine.According to the property of Uighur materia medica,medicine can be divided into hot,cold,wet,dry,dry-hot,wet-hot,wet-cold,and dry-cold types,and according to strength of medicinal properties,this medicine is divided into four classes.Most of the drugs of levels 3 and 4 are credited with toxicity.This article summarizes the property and toxicity of medicines of levels 3 and 4 which are includel in Pharmaceutical Standards-Uighur Medicine (1998) edited by the former State Ministry of Health of the People's Republic of China.

Myeloid-derived suppressor cells (MDSCs) are a heterogeneous population of immature myeloid cells at different stages of maturation.MDSCs mediate the suppression of the anti-tumor immunity,and play a crucial role in cancer tolerance through suppressing the activity of T cells and natural killer cells,inducing T-regs and involving the angiogenesis,and then contribute to the tumor development and metastasis.Promoting the differentiation of MDSCs,reducing its quantity and inhibiting its function by using various methods may contribute to the recovery of patients normal immune status,the tumor progression control,and improvement of the efficacy of other anti-neoplastic therapies.Therefore,possible novel therapeutic approaches targeted at MDSCs could be considered and developed rapidly now.

Objective To study the clinical features of congenital glucose-galactose malabsorption (CGGM),and to improve the understanding of CGGM.Method Clinical manifestations and treatment process of one patient with CGGM in our hospital were retrospectively analyzed.From 1966 to 2016 May,Chinese medical database and PUBMED were searched using Malabsorption syndrome,dehydration,hypernatremia , diarrhea , newborn , carbohydrate metabolism ,andglucose/galactose malabsorption as key words.The clinical features of CGGM reported in literatures were summarized.Result The patient in our hospital was a full-term female infant naturally delivered.The onset of the disease was on the 9th day after birth,and the clinical manifestations included severe diarrhea,severe dehydration,hypernatremia,metabolic acidosis and malnutrition.After intravenous infusion and symptomatic treatment,dehydration,hypernatremia and metabolic acidosis were corrected.However,there was no improvement of diarrhea characterized with watery and acidic stools,and neither was weight gain.Glucose loading test was negative,and fructose loading test was positive.Diarrhea was improved markedly using diagnostic carbohydrate-free formula,so CGGM was diagnosed clinically.SLC5A1 homozygous IVS7-2 A ＞ G mutation was detected which confirmed the diagnosis of CGGM.With carbohydrate-free formula feeding,the body weight of the infant was increased.Followed up for 2 months now,her body length and body weight were at P25 and P22 on growth curve respectively,and no obvious neurological sequela was observed.Our literature review revealed 7 reports including 48 cases of CGGM children.Literature review showed that:most children with CGGM (79.2％) had the onset within 7 days of life;main clinical features included diarrhea (100％),dehydration (100％),and malnutrition (54.2％);22.9％ of patients with carbohydrate-free formula and 27.1％ with fructose matrix formula were fed well;no death was detected,77.1％ had normal weight gain,and 91.7％ had normal development of the nervous system.Conclusion CGGM is rare.The symptoms include severe watery and acidic stools with onset during neonatal period.CGGM is associated with severe complications such as hypertonic dehydration and hypernatremia.The diagnosis is established based upon typical clinical manifestations,sugar loading test and SLC5A1 gene detection.Carbohydrate-free formula feeding is effective.

Objectives To review the clinical features in children with methylmalonic academia (MMA) having the primary clinical manifestations of microangiopathic hemolytic anemia and renal impairment. Methods The clinical data of 4 children diagnosed of MMA with the primary clinical manifestations of microangiopathic hemolytic anemia and renal impairment were retrospectively analyzed from August 2013 to present. Results In the four children (two boys and two girls) with the age from nine months to three years seven mouths, two children were diagnosed with MMA combined with homocysteine, and 2 children were diagnosed with MMA, but there was no homocysteine testing. All four children showed moderate to severe anemia, proteinuria, hematuria, and hypertension. One child had abnormal renal function and thrombocytopenia, and manifested as hemolytic uremic syndrome. Renal biopsy was performed in 2 children and they had glomerular sclerosis lesions with renal tubular necrosis and mesangial proliferative glomerulonephritis respectively. All children were treated with vitamin B12, and the indexes of microangiopathic hemolytic anemia and renal impairment were improved signiifcantly. Conclusions MMA may be combined with microangiopathic hemolytic anemia, renal impairment and even hemolytic uremic syndrome, and the early diagnosis and treatment is required.

OBJECTIVE:To prospectively study the effects of trimetazidine on myocardial remodeling and oxidative stress in patients with hypertensive heart disease (HHD),in order to provide reference for clinical treatment of HHD.METHODS:Eighty-two HHD patients were selected from our hospital during Jan.2014-Jul.2016,and they were divided into control group and observation group by sortition randomization method,with 41 cases in each group.Control group received routine HHD chemical drug (antihypertensive drugs,lipid-lowering drugs,hypoglycemic agents and antiplatelet drugs,etc.) therapy.Observation group was additionally given trimetazidine 20 mg,tid,on the basis of control group.Both groups were treated for 3 months.Before treatment and after 3 months of treatment,SBP,DBP,New York Heart Association (NYHA) cardiac function grade,LVEF,LVESD,LVEDD,LVMI and the levels of GSH-Px,SOD,MDA and ROS were compared between 2 group.The occurrence of ADR was observed in 2 groups.RESULTS:Before treatment,there was no statistical significance in each index between 2 groups (P＞0.05).After 3 months of treatment,SBP and DBP of 2 groups were decreased significantly compared to before treatment (P＜0.01);there was no statistical significance between 2 groups (P＞0.05).There was no statistical significance in NYHA cardiac function grade compared to before treatment or between 2 groups (P＞0.05).LVESD,LVEDD and LVMI of observation group were decreased significantly compared to before treatment (P＜0.05);LVEF was increased significantly compared to before treatment (P＜0.05);LVEDD and LVMI of observation group were significantly lower than control group (P＜0.05).Compared to before treatment,SOD level of control group was decreased significantly,while the levels of GSH-Px and SOD in observation group were increased significantly;MDA and ROS of observation group were significantly lower than those of control group,with statistical significance (P＜0.05).No obvious ADR was found in 2 groups.CONCLUSIONS:Trimetazidine can improve cayocardial remodeling and reduce oxidative stress level of HHD patients with good safety.

The data of a child with sphingosine phosphate lyase insufficiency syndrome (SPLIS) admitted to Children′s Hospital of Hebei Province on February 4, 2020 were retrospectively analyzed.The child had edema, complicated with ichthyosis, adrenal calcification, and hearing loss from the early infancy.Laboratory examination results suggested a low albumin level, hypercholesterolemia, a high proteinuria level, abnormal liver and renal functions, and hyponatremia.The child gave up treatment and died at home.Whole Exome Sequencing (WES) results showed two hete-rozygous mutations of SGPL1 gene (chr10: 72604336, c.134G>A, p.W45X; chr10: 72629563, c.719G>T, p.S240I). SPLIS is inherited in an autosomal recessive manner.It starts in infancy, and affects the kidney, skin, endocrine, nervous and immune systems.It is suggested that SPLIS patients should take genetic examination.Early diagnosis, appropriate intervention, and vitamin B 6 treatment may relieve some symptoms of SPLIS patients.Adeno-associated virus mediated SGPL1 gene replacement therapy can be a novel cure of SPLIS and is worthy of investigation.

This article reported a rare case of harlequin ichthyosis which was indicated with multiple structural abnormalities by prenatal ultrasound and diagnosed by trio-based whole-exome sequencing (Trio-WES). Prenatal diagnosis was performed because the ultrasound at 24 +4 gestational weeks revealed the fetus presenting with eclabium, flattened nose, short mandible, small auricle and abnormal posture of the toes. Copy number variation sequencing (CNV-seq) showed no chromosome aneuploidy or pathogenic copy number variants over 100 kb in the fetal or parental samples. Trio-WES showed that the fetus carried two heterozygous mutations, c.2593-1G>A and c.7444C>T in ABCA12. Sanger sequencing confirmed that c.2593-1G>A, a previously unreported variant, was paternally inherited and c.7444C>T was maternally inherited. Both parents had normal phenotype. The fetus was finally diagnosed with harlequin ichthyosis. After prenatal counseling, the parents made an informed choice to terminate the pregnancy at 28 +4 gestational weeks. The stillborn fetus showed multiple malformations The variants in this case expand the spectrum of variants in ABCA12 gene.

Objective To evaluate the efficacy and safety of tigecycline-based treatment approach on severe infection of patients with hematological diseases. Methods The clinical data of 64 patients who were treated with tigecycline-based treatment approach for severe infection were retrospectively reviewed. The curative effect was evaluated, meanwhile the drug side effects were observed. Results A total of 51 strains of bacteria were isolated from 64 patients, including 12 extended-spectrum β-lactamase(ESBL)and 15 multi-drug resistant strains and the total effective rate was 59.4%(38/64). Five patients diagnosed as carbapenem resistant infection and were treated with the addition dose of tigecycline and 3 patients relieved. Main adverse events were nausea, vomiting, diarrhea and hepatic dysfunction, but all events were slight. Conclusions Tigecycline-based treatment approach has a good clinical efficacy in treating severe infection of patients with hematological diseases, and the side effect is few.Tigecycline-based treatment approach could be used as a new choice for patients non-responding favorably to conventional anti-infective treatment or multiple resistant bacteria.

Objective:To analyze and summarize the efficacy and safety of thalidomide in the treatment of refractory systemic juvenile idiopathic arthritis（sJIA）.Methods:The clinical data of ten patients with refractory sJIA admitted to Department of Nephrology and Immunology in Children's Hospital of Hebei Province from January 2015 to March 2022 were collected，and the clinical manifestations，efficacy and safety of thalidomide in the treatment of refractory sJIA were analyzed retrospectively. Systemic juvenile arthritis disease activity score（sJADAS）was used to evaluate the efficacy of the treatment. Statistical analysis was performed by repeated measurements using general linear models.Results:Among the 10 children（4 males and 6 females）with refractory sJIA，the average age of onset was（7.5±3.3）years. Seven patients were complicated with macrophage activation syndrome at an early stage of disease.The average course of disease was（4.4±1.7）years，and the longest course of disease was 8.3 years. Before the application of thalidomide，all the 10 children experienced relapses（ranging from 2 to 10 times）. The indices of 10 children treated with thalidomide at 6 months and 12 months were compared with those before treatment. Peripheral blood leukocytes［（10.19±3.67）×10 9/L，（8.53±2.83）×10 9/L vs.（16.11±7.81）×10 9/L， F=7.918，11.084， P=0.020，0.009］，C-reactive protein［19.13（0.38，35.21）mg/L，8.05（0.10，18.00）mg/L vs. 59.34（24.20，131.90）mg/L， F=7.030，12.731， P=0.026，0.006］，sJADAS scores［6.00（1.50，12.50）scores，3.00（0，12.50）scores vs. 20.00（11.50，28.00）scores， F=14.710，17.870， P=0.004，0.002］were decreased significantly. The doses of prednisone［0.13（0，0.45）mg/（kg·d），0.02（0，0.06）mg/（kg·d）vs. 0.42（0.16，1.47）mg/（kg·d）， F=5.890，7.623， P=0.041，0.022］were significantly decreased.All the differences were statistically significant. Prednisone was successfully discontinued in 7 cases. Tocilizumab was gradually withdrawn in 3 cases，and tocilizumab administration interval was prolonged in 1 case. None of the 10 children had serious adverse reactions. Conclusion:Thalidomide is clinically effective in the treatment of sJIA，and can reduce the required dose of prednisone and prolong the tocilizumab free remission.
