Childhood simple obesity has become a significant public health issue in China. Modern medicine primarily relies on lifestyle interventions and often suffers from poor long-term compliance， while pharmacological options are limited and associated with potential adverse effects. Traditional Chinese Medicine （TCM） has a long history in the prevention and management of this condition， demonstrating eight distinct advantages， including systematic theoretical foundation， diversified therapeutic approaches， definite therapeutic efficacy， high safety profile， good patient compliance， comprehensive intervention strategies， emphasis on prevention， and stepwise treatment protocols. Additionally， TCM is characterized by six distinctive features： the use of natural medicinal substances， non-invasive external therapies， integration of medicinal dietetics， simple exercise regimens， precise syndrome differentiation， and diverse dosage forms. By combining internal and external treatments， TCM facilitates individualized regimen adjustment and holistic regulation， demonstrating remarkable effects in improving obesity-related metabolic indicators， regulating constitutional imbalance， and promoting healthy behaviors. However， challenges remain， such as inconsistent operational standards， insufficient high-quality clinical evidence， and a gap between basic research and clinical application. Future efforts should focus on accelerating the standardization of TCM diagnosis and treatment， conducting multicenter randomized controlled trials， and fostering interdisciplinary integration， so as to enhance the scientific validity and international recognition of TCM in the prevention and treatment of childhood obesity.

Objective:To analyze clinical characteristics and genetic characteristics of children with ATP sensitive potassium passage (K ATP-HI). Methods:Forty-five children with genetically confirmed K ATP-HI and their families admitted to Beijing Children′s Hospital of Capital Medical University between February 2002 and December 2018 were selected as the study subjects. A detailed retrospective analysis of the patient's clinical characteristics, diagnosis and treatment process, disease-causing gene carrying status and later follow-up data was performed. ABCC8/KCNJ11 gene was sequenced by second-generation sequencing technology. Results:Among 45 children with K ATP-HI, 34 cases (75.6%) were neonatal onset, the first symptoms of 21 cases (46.7%) were convulsions. 39 cases had been treated with diazoxide, including 12 cases (30.8%) with good efficacy, 16 cases (41%) with poor efficacy and 11 cases with uncertain efficacy. Octreotide was further applied in 18 patients with uncertain or ineffective efficacy after diazoxide treatment, and 13 cases (72.2%) were effective, 3 cases were ineffective, and 2 cases were uncertain. 10 CHI patients who were ineffective to drug treatment or had clearly focal lesions confirmed by 18F-dopa positron emission by computed tomography ( 18F-DOPA PET) scans had undergone surgical treatment, 8 of which underwent partial pancreatectomy and blood glucose returned to normal after the operation; the other 2 cases underwent subtotal pancreatectomy and both had secondary diabetes after operation. Among 45 children with K ATP-HI, 1 case carried both ABCC8 and KCNJ11 mutations, 10 cases carried ABCC8 compound heterozygous mutations, and the remaining 34 cases carried ABCC8/KCNJ11 single genetic mutation. Among them, 21 cases had paternal inheritance, and 3 cases had maternal inheritance, 6 cases were identified with de novo mutations. Conclusions:Diazoxide treatment was ineffective for most K ATP-HI children, but octreotide had a higher effective rate. Partial pancreatectomy for focal type patients had a higher cure rate, and there was a risk of secondary diabetes after subproximal pancreatectomy, so it was very important to clarify the histological type of children before surgery. ABCC8 gene mutations and KCNJ11 gene mutations were the main pathogenic genes of K ATP-HI. Among patients carrying mutations in single ABCC8 or KCNJ11 gene mutation, K ATP-HI inherited by paternity were the majority. Some K ATP-HI children can relieve the hypoglycemia symptoms by themselves.

Objective:The serum levels of pepsinogen (PG) and gastrin 17 (G17) in patients with primary gastric cancer were determined, and the correlation between them and the degree of tumor malignancy was analyzed to provide a reliable basis for clinical diagnosis and treatment.Methods:The study group included 155 patients with primary gastric cancer treated in Peking University (PKU) Care Luzhong Hospital from January 2019 to January 2020, and with the same period to the hospital physical examination of 100 cases of healthy volunteers as control group. Peripheral venous blood samples were taken from all subjects for detection, and serum PG Ⅰ, PG Ⅱ, G17 level were compared and analyzed, and PG Ⅰ/PG Ⅱ (PGR) was calculated. The indexes of gastric cancer patients in different stages and tumor node metastasis (TNM) stages were analyzed, and the receiver operating characteristic (ROC) curve was drawn to analyze the efficacy of the above indicators in the diagnosis of gastric cancer.Results:The levels of PG Ⅰ and PGR in the study group were significantly lower than those in the control group ( P<0.05), and the serum level of G17 was significantly higher than that of the control group, while the difference of PG Ⅱ level was not statistically significant ( P>0.05). Based on the progress of tumor focus, serum PG Ⅰ and PGR in patients with advanced gastric cancer were significantly lower than those in patients with early gastric cancer ( P<0.05), while serum G17 level were higher in patients with early gastric cancer ( P<0.05). Based on TNM stage, serum PG Ⅰ level decreased significantly with the increase of tumor stage ( P<0.05), while serum G17 level increased significantly ( P<0.05). The ROC curve showed that the combined detection of serum PG Ⅰ, PG Ⅱ, PGR and G17 was superior to single index in the diagnosis of gastric cancer. The area under curve (AUC) of combined detection was the highest, with sensitivity and specificity of 83.87% and 76.77%, respectively. Conclusions:The expression levels of serum PG Ⅰ, PGR and G17 are correlated with the degree of malignancy of primary gastric cancer. Moreover, combined detection and diagnosis of primary gastric cancer has good efficacy and important clinical value.

Objective To analyze the clinical characteristics and gene mutations of 56 patients with congenital hyperinsulinism(CHI)and to provide a theoretical basis for clinical diagnosis and treatment of CHI.Methods Fifty-six children who were diagnosed as CHI between February 2002 and January 2016 in Beijing Children's Hospital Affiliated to Capital Medical University were selected as research subjects.A retrospective study was done about the clinical data and the treatment procedures of the 56 patients,such as perinatal conditions,clinical manifestations,laboratory data,treatments,prognosis and so on.Polymerase chain reaction(PCR)-DNA technology or next-generation sequencing technology was used to analyze the CHI relevant genes of the 56 patients.Results Thirty of the 56 patients carried CHI gene mutation.(1)Twenty-three of 56 patients(41.0％)carried ABCC8/KCNJ11 gene mutations:4 of 23 patients carried complex heterozygous mutation,1 of 23 patients carried both ABCC8 and KCNJ11 gene mutation,1 of 23 patients carried maternally inherited ABCC8 gene mutation,12 of 23 patients carried paternally inherited ABCC8 gene mutation,1 of 23 patients carried paternally inherited KCNJ11 gene mutation,3 of 23 patients carried de novo ABCC8 gene mutation,1 of 23 patients had unknown genetic way,19 of 23 patients were treated with Diazoxide,2 of 19 patients were responsive to Diazoxide,7 of 19 patients were unresponsive to Diazoxide and 10 of 19 patients were uncertain to Diazoxide.(2)Five of 56 patients(8.9％)carried GLUD1 gene mutation,4 of 5 patients were treated with Diazoxide and they were all responsive to Diazoxide.(3)One of 56 patients(1.7％)carried de novo GCK gene mutation,responsive to Diazoxide treatment.(4)One of 56 patients(1.7％)carried maternally inherited SLC16A1 gene mutation,responsive to Diazo-xide treatment.Conclusions The ABCC8 gene and GLUD1 gene mutation are the main causative genes of CHI.The GCK gene and SLC16A1 gene mutation are in the minority.Most ABCC8 gene and KCNJ11 gene mutation are unresponsive to Diazoxide treatment.

Objective To explore the influence of abnormal donor hepatic artery on hepatic artery and biliary complications after liver transplanta?tion,and summarize the hepatic artery reconstruction procedures during transplantation. Methods The clinical data of 210 cases of liver transplan?tation conducted in our hospital from May 2005 to April 2015 were retrospectively searched for the study,including 42 with abnormal donor hepatic artery. Results Among the 210 liver transplantation,42 cases exhibited abnormal donor hepatic artery,and the aberration rate was 20.0%. Mean volume of blood flow of abnormal group and normal group was 4.7±95.1 mL/min and 190.9±101.6 mL/min,respectively. There was no statistic differ?ence(P=0.519). Twelve cases had arterial complications,the incidence rate was 5.71%,and there was no statistic difference between each group (χ2=0.72,P>0.05). Twenty five cases got biliary complications,the incidence rate was 11.9%,and there was no statistic differences between each group(χ2=0.05,P>0.05). Conclusion There was no statistic difference of mean volume of blood flow after arterial reconstruction between two groups. Liver transplantation with abnormal arterial reconstruction will not increase the incidence rate of arterial and biliary complications.

Objective To study the protective effect of minocycline against ischemia-reperfusion injury after liver transplantation and its molecular mechanism after circulatory death in rats.Methods The rat donation after circulatory death (DCD) liver transplantation model was established by using magnetic-ring method.The donor and recipient were male SD rats.The rats were divided into sham operation group (SHAM group),liver transplantation group,minocycline group (MIN group),atractyloside + minocycline group (ATR + MIN group),24 rats in each group.In the MIN group,10 mg/kg minocycline was injected through the dorsum vein of the penis after reperfusion.The ATR + MIN group was injected with 2 mg/kg atractyloside.The open status of mitochondrial permeability transition pore (mPTP) was detected at 2,6,and 24 h after operation.Western blotting and immunohistochemistry were used to detect the expression of caspase3 and cyt c.Serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels were determined.Liver tissues were stained with hematoxylin-eosin (HE) and pathological changes were evaluated by Suzuki's standard.The survival of each group was calculated.Results As compared with liver transplantation group and ATR+ MIN group,the mPTP opening of MIN group decreased (P＜0.05),the expression of caspase3 and cyt c and the serum ALT and AST levels decreased significantly (P＜0.05),liver tissues injury was alleviated (P＜0.05),and the survival rate increased significantly after 30 days (P ＜0.05).There was no significant difference between liver transplantation group and ATR + MIN group (P ＞ 0.05).Conclusion Minocycline reduces ischemia-reperfusion injury in DCD liver transplantation in rats probably by inhibiting the mPTP opening,and preventing cyt c release and caspase3 activation to reduce hepatocyte apoptosis.This effect can be blocked by mPTP opener.

Objective:To study the effect of immunological molecules expressive state upon the telomerase activation ( TA) of bone marrow mononuclear cells ( BMMNC ) in the hemopoietic microenvironment of patients with immune related hematocytopenia ( IRHS) ,and to explore the immunologic mechanism as well as the clinical significance of hematoclasis in marrow of IRHS patients .Methods:①TRAP-PCR-ELISA method was performed to detect the TA of BMMNC in marrow of 366 IRHS patients before and after therapy.②The molecules HLA-DR,anti-hunman IgG,FcγⅡR,mannose receptor ( MR),IL-17A and its receptor ( IL-17AR) were analysed by immunochemistry and immunofluorescence staining .③The flow cytometric ( FCM) was used to analyse the proportion of CD3+CD4+T cells as well as CD3+CD8+T cells ,CD3-CD19+B cells and CD3-CD16/56+NK cells in peripheral blood lymphocyte.60 cases of health examination were selected as the control group , and 30 cases hypoferric anemia patients were selected as disease control.The differences between patient group and control group were analysed with statistic method .Immunochemistry and immunofluo-rescence staining were performed to in situ analyze the activation-characteristics of immunocyte in bone marrow slides of IRHS ,and the dependablity of cellular immunologic injury was also checked.Results: ①The levels of TA was 0.261 7 ±0.021 6 before treatment , higher than the disease control group (0.061 6±0.031 3 ,P<0.01).Among of them HLA-B27+patients were higher than HLA-B27-patients (0.301 3±0.020 6 vs.0.192 3±0.012 9,P<0.05).Serious IRP patients with HLA-B27+IgG+were obviously higher than HLA-B27-IgG+patients (0.401 6±0.017 2 vs.0.221 1±0.011 0,P<0.01).②In marrow of HLA-B27+IgG+patients,both cell immunity and humoral immunity were in disorder in the hemopoietic microenvironment ,and immonocyte in marrow expressed HLA-DR, FcγⅡR,IL-17A,IL-17RA and MR,and Th,Ts,B cell and NK cell in peripheral blood increased in different degree ,inducing the in-flammation of haemocyte and lead to destruction.③Humoral immunity was in the dominant level in morrow;humoral immunity of HLA-B27-IgG+patients,immonocyte expressed FcγⅡR in high level,but IL-17A was seldom expressed,only CD19+B cell was increased slightly ,the antibody dependent cellular cytotoxicity ( ADCC) was the main mode of destruction.After therapy glucocorticoids associated with ciclosporin A ,the TA level of BMMNC decreased to 0 with devitalization.Conclusion: The telomerase activation of bone marrow mononuclear cells in IRHS is related with the immune state of hemopoietic microenvironment and the pathologic lesion degree of hema -topoietic cell in marrow.It is viral infection and immunological activation as well as a variety of inflammatory factors play a part in the immunologic injury that might be an important factor of the enhancement in TA.

Objective To investigate the biological effect of anti-leukemic cells induced by eosinophilic granulocyte (EOS) in bone marrow of patients with chronic myelogenous leukemia (CML).Methods The BCR-ABL fusion gene as well as the expression of IL-12 and IL-17 mRNA were performed by RT-PCR.The serum concentrations of cytokine IL-12 and IL-17 were determined by enzyme-linked immuno sorbent assay (ELISA).Immunochemistry staining and cytochemistry staining were used to observe the peroxydase (POX) and human Leukocyte antigen (HLA)-DR expression of EOS in bone marrow.Immunofluorescence staining was used to observe mannose receptor (MR),IL-12,IL-17A and IL-17receptor A (IL-17RA) expression of EOS.The results between the CML patients and the healthy controls were compared.Results Serum levels of IL-12 and IL-17 were higher in the 60 CML patients [(196.33 ±21.79) ng/L and (36.55-±3.01) ng/L] than those in the controls [(96.60 ±4.92) ng/L and (23.74 ±1.36) ng/L].In the 32 patients with activated EOS,the levels of IL-12 and IL-17 were (273.12 ± 17.16)ng/L and (40.11 ± 6.13) ng/L,which were significantly higher than those in the non-activated EOS [(126.16 ± 14.27) ng/L and (28.14 ±5.29) ng/L] (P values ＜0.01).IL-12 and IL-17 mRNA were expressed in activated EOS,while BCR-ABL fusion gene was not found.The amounts of EOS were increased abnormally in the bone marrow and peripheral blood of the CML patients with POX positive staining in the cytoplasm and weakly positive HLA-DR staining.It was observed easily by a microscope that EOS could attack leukemic cells in bone marrow through adhesion,capture and phagocytosis.Activated EOS could express IL-12,IL-17A and MR,which was related with the serum levels of these cytokines.Conclusions Activated EOS in bone marrow of CML patients could express IL-12 and IL-17.Activated EOS could induce coup injury to leukemic cell by releasing POX and expressing IL-12 and IL-17.It can also capture or swallow target cells via the expression of MR on the membrane.EOS may play an important role in the anti-tumor immunologic function in bone marrow of CML patients.

Objective To evaluate the renal protective effect of targeted abdominal perfusion pressure (APP) treatment in intra-abdominal hypertension (IAH) and further investigate its related mechanisms.Methods Twelve healthy pigs were randomly divided into experimental group and control group,each group had 6 pigs.All animals were collected urine volume each hour,continuously monitored mean arterial pressure (MAP) and renal cortical blood flow after anesthesia.IAH models were established by intraperitoneally injecting carbon dioxide in all animals,the baseline MAP,intra-abdominal pressure (IAP)and APP were obtained before IAH models established.In both groups,IAP was raised gradually from 0 mm Hg to 10 mm Hg,20 mm Hg and 30 mm Hg.In control group,IAP was maintained at 30 mm Hg for 8 hours with-out any other interventions.In experimental group,the animals were intravenously given with norepinephrine in order to get a target level of APP equal to its baseline values after 15 minutes of the onset of 30 mm Hg IAP.Changes of renal cortical blood flow,serum creatinine,TNF-α,IL-6 and urine IL-18 with the alteration of IAP in both groups were explored.Animals were then sacrificed for renal histopathology after 8 hours of the onset of 30 mm Hg IAP.Results With the increase of IAP,renal cortical blood flow in both groups was significantly decreased (P ＜ 0.01).Compared to its baseline,serum Cr and urinary IL-18 were significantly up-regulated after the maintenance of IAP at 30 mm Hg for 6 hours in both groups (P ＜ 0.05).However,in experimental group,which utilized a strategy of targeted APP,significant improvement of the renal cortical blood flow was observed (P ＜ 0.01),and urinary IL-18 was significantly lower than the control group (P ＜ 0.05).Renal histopathological examination found no obvious abnormalities either in control group or in experimental group.Conclusions The targeted APP treatment may have some renal protective function within the first 8 hours of IAH by improving renal cortical blood flow rather than affecting systemic inflammatory response.

Objective To summarize our experience in the liver transplantation from the donation after cardiac death (DCD).Methods The livers from three DCD donors (2 cases of brain trauma and 1 case of cerebral hemorrhage) were harvested according to the Guidelines for Donation after Cardiac Death in China.These grafts were orthotopically transplanted into three recipients including 2 cases of decompensative hepatic cirrhosis and 1 case of primary liver cancer.The warm ischemic time ranged from 7.5 to 10 min and the cold ischemic time was 4.5,8.2 and 6.5 h respectively.Postoperative immunosuppressive regimens included prednisone,FK506 and mycophenolate mofetil (MMF).Antibiotics and anticoagulatants were used accordingly.Results All of the 3 recipients obtained normal liver function within 3 weeks since the grafts were implanted without PNF,thrombosis and rejection.No postoperative complications occurred in 3 recipients during the follow-up period of 2 to 9 months with normal liver function.Conclusion The liver transplant from DCD donor showed good results in our center.Chinese group Ⅲ of DCD donor,UW score above the middle level and the short warm ischemic time are three keys ensuring the success of the liver transplant from DCD donors.
