Objective Although heart transplantation (HTx) has become a standard therapy for end-stage heart diseases,experience with pediatric HTx is limited in China.In this article,we will try to provide the experience with indications,complications,perioperative management,immunosuppressive therapy,and survival for pediatric HTx based on our clinical work.Method This is a retrospective chart review of the pediatric patients undergoing HTx at Department of Cardiovascular Surgery of Union Hospital from September 2008 to December 2015.We summarized the indications,surgical variables,postoperative complications,and survival for these patients.Result Twenty-three pediatric patients presented for HTx at Union Hospital of Tongji Medical College,of whom 12 were male.The age at the time of transplantation ranged from 3 months to 18years (median 14 years).Patient weight ranged from 5.2 kg to 57.0 kg (median 36.0 kg).Pretransplant diagnosis included cardiomyopathy (16 cases),complex congenital heart disease (5cases) and tumors (2 cases).All recipients received ABO compatible donor hearts.Postoperative complications occurred in 14 patients,including cardiac dysfunction,arrhythmia,pulmonary infection,renal dysfunction,and rejection.Two of them experienced cardiac failure and required extracorporeal membrane oxygenation.The immunosuppression regimen was comprised of prednisone,a calcineurin inhibitor,and mycophenolate.All patients recovered with New York Heart Association (NYHA) Class Ⅰ Ⅱ cardiac function and were discharged.Only one patient suffered sudden death 19 months after transplantation.Conclusion Orthotopic HTx is a promising therapeutic option with satisfactory survival for the pediatric population in China with end-stage heart disease.

Objective: To explore the structural domains of the CENP-E protein that interact with Mps1 protein.Methods: Two recombinant vectors named pEGFP-CENPE2(containing 674-1085 amino acids of CENP-E protein) and pEGFP-CENPE 3(containing 1200~2134 amino acids of CENP-E protein) were transfected into human embryo kidney 293(HEK293) cells respectively.The respective energy transfer efficiency(Ef) between either EGFP-CENPE2 and Mps1,or EGFP-CENPE3 and Mps1 were detected by FRET through selective photobleaching of the acceptors.Results: Both recombinant proteins expressed in HEK293 cells transfected by the recombinant plasmids were found to co-localize with the Mps1 protein as confirmed by confocal microscopy.The Ef between EGFP-CENPE3 and Mps1 protein was [(12.63?0.48)%,n=30] and that between EGFP-CENPE3 and Mps1 protein was [(3.17?0.21)%,n=30] as revealed by the results from FRET,the result of FRET was confirmed by co-Immunoprecipitate(CO-IP) method.When compared with that between the control and Mps1,the Ef between EGFP-CENPE3 and Mps1 was significantly higher(p

OBJECTIVETo study the pathologic change and molecular regulation in cell proliferation and apoptosis of gastric mucosa in rats with chronic atrophic gastritis (CAG), and evaluate the possible mechanisms.

METHODSRats were administered with 60% alcohol or 2% salicylate sodium, 20 mmol/L deoxycholate sodium and 0.1% ammonia water to establish chronic atrophic gastritis (CAG) models. The gastric specimens were prepared for microscopic view with hematoxylin and eosin (H-E) and alcian blue (A-B) stain. The number of infiltrated inflammatory cells, the thickness of the mucosa gland layer (microm) and the number of gastric glands were calculated. The damage of barrier in mucosa with erosion or ulceration, and the thickness of mucin were examined by scanned electron microscope (SEM). The levels of PGE(2), EGF (epiderminal growth factor) and gastrin in the serum were measured with radioimmunoassay or ELISA method. The immunohistochemistry method was used to observe the number of G cells, the expression of protein of EGFR (EGF receptor), C-erbB-2, p53, p16 and bcl-2 in gastric tissue.

RESULTSUnder SEM observation, the gastric mucosa was diffused erosion or ulceration and the thickness of mucin was decreased. Compared with normal rats, the grade of inflammatory cell infiltration in CAG rats was elevated, whereas the thickness and number of gastric gland were significantly lower (P<0.05). Compared with normal level of (0.61+/-0.28) microg/L, EGF in CAG (2.24+/-0.83) microg/L was significantly higher (P<0.05). The levels of PGE(2) and gastrin in serum were significantly lower in CAG rats than that in normal rats (P<0.05). Immunohistochemistry detection showed that the number of G cell in antrum was lower in CAG group (P<0.05). Immuno-stain showed EGFR protein expression in the basal and bilateral membrane, and the cytoplasma in atrophic gastric gland, while negative expression was observed in normal gastric epithelial cells. Positive staining of p53 and p16 protein was localized in the nucleus of epithelial cells. The former was higher positively expressed in atrophic gland, while the later was higher positively stained in normal gastric tissue. bcl-2 protein was positively stained in the cytoplasma in atrophic gastric gland, while very weakly stained in normal gastric tissue.

CONCLUSIONThe pathological findings in gastric gland accorded with the Houston diagnostic criteria of antrum-predominant CAG. CAG in rats was related with the damage of barrier in gastric mucosa and the misbalance of cell proliferation and apoptosis. There was high protein expression of oncogene, while inhibitor of suppressor gene in CAG rats indicated high trend of carcinogenesis.

OBJECTIVETo observe the efficacy and safety of Jingui Shengqi Pill in treating partial androgen deficiency in aging males (PADAM), and to explore the new approach in improving the quality of life in PADAM patients.

METHODSForty patients with PADAM were treated with JSP, the efficacy was evaluated with international index of erectile function (IIEF) scoring, PADAM questionnaire scoring, hormone, prostatic specific antigen (PSA), etc., and the data before treatment were compared with those after treatment in the same group.

RESULTSAfter 3 months of treatment, PADAM scoring and IIEF scoring were all significantly improved. Symptoms regarding physical ability, vasomotion, and psychical and mental condition all got improved more markedly than symptoms regarding sexual hypofunction. The serum level of testosterone was 3.85 +/- 0.36 before treatment and 5.02 +/- 0.83 after treatment (P < 0.05); luteinizing hormone of 7.33 +/- 2.14 and 4.84 +/- 1.43 (P < 0.01), follicle-stimulating hormone of 10.22 +/- 4.48 and 6.47 +/- 3.28 (P < 0.01), respectively. The level of PSA failed to change significantly (1.94 +/- 0.55 and 2.06 +/- 0.47, P > 0.05).

CONCLUSIONJSP is effective and safe in treating PADAM, the mechanism of it is different from supplementing extrinsic androgen. It may have produced the effect by means of favorably regulating the condition of sex hormone to improve the balance of pituitary-sex gland axis, so it has more extensive clinical application.

Gastric cancer, a common malignant tumor in digestive system with high morbidity as well as mortality rate, is insidious at the onset and lack of effective treatments so far. A growing number of studies have shown that exosome-derived miRNAs play an important role in the occurrence and development of gastric cancer. Autocrine exosome miRNAs from gastric cancer cells regulated tumor growth, recurrence, metastasis and drug resistance, etc. Moreover, exosomal miRNAs in the tumor microenvironment can be delivered into cancer cells to facilitate intercellular communication, thus affecting the progress of gastric cancer. Due to exosomes, which were released into circulation from tumor cells, contain abundant, specific and stable miRNAs, exosome-derived miRNAs have a great potential to be used as novel diagnosis biomarkers and treatment targets of gastric cancer.(Chin J Lab Med, 2018, 41: 499-502)
