[Objective] To introduce the experience of Professor ZHANG Biao in the treatment of infantile dyspepsia. [Methods] Through the long-term study with Professor ZHANG, large amounts of medical records are collected and generalized, so that the experiences concerning infantile dyspepsia are summarized, when and how to choose activation, tonification or digestion depends on excess and deficiency,and proven cases are presented. [Results] It is thought that infantile dyspepsia mostly belongs to excess syndrome, or excess syndrome combined with deficiency syndrome, so the treatment is heiping digestion, tonifying spleen and harmonizing stomach. Professor ZHANG thinks that the cause of children's dyspepsia is the weakness in spleen and stomach eventually. It is characterized by excess in syndromes and deficiency in root causes. Its clinical manifestations are concurrence of excess and deficiency. As for the treatment, there's no need to wait for the pathogenic qi to disappear. The basic principle of treatment is always to activate the spleen, regulate qi and help digestion. Professor ZHANG raises that syndromes with more deficicency than excess are treated by activating spleen, which is complemented by tonification. That is to say, activation and tonification are combined, while helping digestion is considered, also. But as to syndromes with more excess than deficiency, the treatment will be activating spleen combined with helping digestion, also with regulating qi. He also cares for children 's regulating and giving reasonable advice. [Conclusion]According to the children's characteristics of physiology and pathology, we should pay more attention to excess and deficiency to choose better method, at the same time, proper feeding and teaching are also important.

BACKGROUND:Stem cell transplantation can, in theory, rebuild the immune system and regulate immunologic function. In addition, the transplanted stem cells may differentiate into tissues or cells we want. Therefore, this intervention may restore gastrointestinal inflammatory lesion and exert therapeutic effect on inflammatory bowel diseases (IBD). OBJECTIVE:To review the application of different kinds of stem cells in IBD treatment. METHODS:A computer-based search of CNKI, PubMed and FMJS was performed for articles concerning stem cel transplantation and IBD published after January 2002. The key words were stem cells, inflammatory bowel diseases, Crohn's diseases, ulcerative colitis, cell therapy in Chinese and English respectively. At last, 49 articles were included in result analysis. RESULTS AND CONCLUSION: Embryonic stem cells and adult stem cells both have certain therapeutic benefits in IBD. But which kind of stem cell is the safest and most efficacious cannot be confirmed, and at the same time the most effective and the optimal dose and way of transplantation of such cells are still unclear. All in all, there is still a lot of work to do to remove the obstacles.

Objective To evaluate the influence of diabetes on cancer stage,treatment,and overall survival rate among newly diagnosed cancer patients,and the correlation between diabetes mellitus and cancer.Methods Total 16 890 newly diagnosed cancer patients were analyzed retrospectively.Morbidity rate of diabetes mellitus,stage of cancer,cancer treatment,survival rate,and comorbidities were collected and compared.Results 9.57% of those 16 890 cancer patients were suffering from diabetes by the time of cancer diagnosis.The prevalence of diabetes was high among patients with pancreas cancer (18.76%),renal cancer (16.76%),colorectal cancer (12.34%),and uterine cancer (10.97%).Colorectal cancer was often diagnosed at an advanced tumor stage.Compared with those without diabetes,diabetic patients with colorectal cancer,gastric cancer,and endometrial carcinoma were more likely to receive surgical treatment.Unadjusted analyses showed that the median survival time and percent alive at 3 years in cancer patients with diabetes were significantly reduced in all types of cancers,except for prostate cancer,as compared with those cases without diabetes.After adjustment for occurrence of cardiovascular disease,diabetic patients with colorectal,breast,endometrial,ovary,prostate,kidney,and lung cancers still had a 8%-55% increased risk of mortality compared to cancer patients without diabetes mellitus (P＜0.05).Conclusion The prevalane of cancer in diabetes is higher than non-diabetics.Diabetic cancer patients are frequently treated less aggressively and have a worse prognosis compared to those without diabetes.

Objective To determine whether glucagon-like peptide-1 (GLP-1) receptor PET/CT with 68Ga-exendin-4 is accurate in localizing insulinomas, by comparing with conventional imaging techniques.Methods In this prospective cohort study, patients with biochemically proven endogenous hyperinsulinemic hypoglycemia from March 2014 to November 2016 were recruited consecutively.68Ga-exendin-4 PET/CT, CT, MRI, endoscopic ultrasound (EUS), and SSTR imaging were performed before elective surgery.Surgical pathology results were considered as the gold standard.Sensitivity based on patient-analysis and positive predictive value (PPV) based on lesion-analysis were calculated and compared using χ2 test and generalized score test.Results A total of 109 patients were recruited (47 males, 62 females;average age (45.1±14.8) years), and 96 of them with insulinomas proved pathologically were included in the main assessment.Thirteen patients with positive 68Ga-exendin-4 PET/CT findings did not undergo surgical intervention.Based on patient-analysis, the sensitivities of 68Ga-exendin-4 PET/CT, CT, MRI, EUS and SSTR imaging for detecting insulinomas were 98.96%(95/96), 81.25%(78/96), 79.41%(54/68), 81.40%(35/43) and 21.84%(19/87), respectively.Based on lesion-analysis, the PPV of the above 5 methods were 100%(102/102), 97.56%(80/82), 95.16%(59/62), 83.72%(36/43) and 90.48%(19/21), respectively.68Ga-exendin-4 PET/CT showed the highest diagnostic sensitivity than others (all P<0.01) and higher PPV than MRI, EUS and SSTR imaging (all P<0.05).Conclusion 68Ga-exendin-4 PET/CT is a highly sensitive imaging technique for detection of insulinoma.

[ ABSTRACT] AIM: To investigate the role of anterior thalamic nucleus in trigeminal nerve electrostimulation ( TNS)-induced effects on seizures and hippocampal damage.METHODS: The rats were intraperitoneally injected with pilocarpine to induce chronic epilepsy, and then received sham treatment, TNS treatment and TNS treatment after stereotac-tic lesion to the anterior thalamic nucleus.The TNS treatment lasted for 1 month in each group.Another injection of pilo-carpine was conducted to induce seizures, and the severity and duration of seizures were quantitatively evaluated.TUNEL, Fluoro-Jade B ( FJB) and Nissl staining were applied to determine in situ apoptosis, neuronal degeneration and neuron loss in the hippocampal CA1 area respectively.RESULTS:Compared with TNS group, TNS treatment after stereotactic lesion to the anterior thalamic nucleus significantly increased the severity and duration of seizures (P<0.05), and the numbers of TUNEL positive cells, FJB positive cells and lost neurons in the hippocampal CA1 area (P<0.01).CONCLUSION:Anterior thalamic nucleus plays a role in TNS-induced reduction of seizures and hippocampal damage.The mechanisms might be due to the chronically activation of the cortex through anterior thalamic nucleus pathway induced by TNS, resulting in the down-regulation of neuronal excitatory susceptibility.
