Objective To analyze the incidence, clinical feature and late complications, and treatment for diabetes ketoacidosis (DKA) in children with type 1 diabetes mellitus.Methods Ninty children with type 1 diabetes mellitus within 10 years were retrospectively reviewed.The onset situation,clinical feature and long-term complication,and treatment of DKA were analized.Results High morbidity was found in 10 to 16 years old children.DKA was often caused by infection; late complications of diabetes mellitus was resulted from interrupted injection of insulin.Conclusions Emergency treatment for DKA may involve the injection of small dose insulin,correction of the disorder of water and electrolysis and regulation of acid-base.The education of patients and parents about diabetes mellitus and long-term injection of insulin are of importance in preventing the complications.

Undifferentiated and differentiated 3T3-L1 adipocytes were treated with 100 ng/ml tumor necrosis factor-?(TNF-?),and peroxisome proliferator-activated receptor-?2 (PPAR-?2) mRNA expression and adiponectin secretion in cultured cells were measured.The results showed that TNF-?suppressed PPAR-?2 mRNA expression and adiponeetin secretion in 3T3-L1 adipocytes (P

OBJECTIVEThe aim of this paper was to evaluate the treatment outcome of multimodal treatment for 196 patients with locoregional recurrent esophageal cancer after curative treatment and to determine the prognostic factors of recurrence.

METHODSOne hundred and ninety six patients with locoregional recurrent esophageal cancer curatively treated in our hospital were included in this study. Kaplan-Meier method was used to analyze the survival rate. Log rank test was used to evaluate the difference between the groups. Multivariate survival analysis was conducted using a Cox proportional hazard regression model with a backward stepwise procedure.

RESULTSThe overall 1-, 2- and 3-year survival rates were 29.8%, 5.9% and 4.0%, respectively, with a median survival time of 8.0 months. The univariate analysis showed that ECOG PS, the interval between initial treatment and recurrence, the regimens of initial treatment and retreatment were independent prognostic factors. The multivariate analysis showed that the regimens of initial treatment and retreatment were independent prognostic factors. Retreatment methods significantly influenced the survival. The median survival time of chemoradiotherapy, radiation therapy alone, chemotherapy alone, EGFR-TKI and best supportive care were 13.0, 7.0, 6.0, 4.0 and 3.0 months, respectively (P = 0.000).

CONCLUSIONSThe prognosis of patients with locoregional recurrent esophageal cancer after curative treatment is poor. The main prognostic factors are the regimens of initial treatment and retreatment. Multimodal treatment including radiotherapy and chemotherapy may improve the long-term survival of the patients.

Objective To observe the protective effects of a mixture for protecting liver and supplementing stomach (保肝益胃合剂) on rat acute liver damage induced by carbon tetrachloride (CCl_4). Methods The model of rat acute liver damage was established by injection of CCl_4 2 ml/kg into the abdominal cavity.The rat models were treated respectively by the mixture for protecting liver and supplementing stomach 30 g?kg~(-1)?d~(-1),the polyene phosphatide acid radical choline capsule [Yi Shanfu (易善复), 180 mg?kg~(-1)?d~(-1)],the glycyrrhizic acid diaminogen capsule [Gan Lixin (甘利欣),30 mg?kg~(-1)?d~(-1)] infused into the stomach.The activities of serum alanine transaminase (ALT) and aspartate transaminase (AST) were detected.In the mean time,the liver pathological changes were observed,the degree of liver cell necrosis was evaluated,and the rat mortality was noted in various groups of treatment.Results The values of ALT,AST and the score of liver cell necrosis in the group treated with the mixture for protecting liver and supplementing stomach [(1.168?1.066) kU/L,(1.845?2.212) kU/L,(0.56?0.53) score] were significantly lower than those in the model group [(4.982?3.502) kU/L,(7.030?3.616) kU/L, (1.38?0.92) scores],and all the differences being statistically significant (all P

OBJECTIVETo explore the significance and the role of the p53 gene mutation in the exon 4 to 8 in keloid fibroblasts.

METHODSTissue samples from twelve patients with keloid and twelve hyperplastic scar respectively were harvested for in vitro culture of fibroblasts, and normal skin samples from the same patients were employed as the control. Polymerase chain reaction-based single-strained conformational polymorphism (PCR-SSCP) and DNA sequencing were employed to detect p53 gene mutations of the fibroblasts.

RESULTSThe points and frameshift mutations in the exon 4, 5, 6, 7 of p53 gene were identified in 9 of the 12 keloid tissue samples. No p53 gene mutation was detected in all hyperplastic scar and normal skin samples.

CONCLUSIONp53 gene mutation might play an important role in the formation and development of keloids.

OBJECTIVETo develop a HPLC method to determine the contents of aristolochic A in aristolochia debilis and Asarun spp..

METHODMethanol-water-formic acid extracts were separated on an Alltech C18 column with methanol-water-acetic acid (68:32:1) as mobile phase. The flow rate was 1.0 mL x min(-1). UV detection wavelength was 390 nm. Column temperature was 35 degrees C.

RESULTAristolochic acid A was separated well. The relationship of injection amounts and peak areas was linear (r = 0.9999) the range of 0.12-1.89 microg x g(-1) and the recovery rate was 101.8% (n = 5). 11 samples of aristolochia debilis which bought from different areas in China were determined, and the contents of aristolochic acid A varied from 0.9 to 2 mg x g(-1). The difference of the contents in Asarum spp. was obvious. The highest is 0.35, and aristolochic acid A couldn't be detected in one sample.

OBJECTIVETo study the related factors of right recurrent nerve nodal involvement in esophageal cancer.

METHODS280 patients with thoracic esophageal cancer received esophagectomy and right recurrent nerve node dissection. The clinicopathological data were analyzed retrospectively. Univariate data were analyzed by chi-square test, and multivariate data were analyzed by logistic regression.

RESULTSThe right recurrent nerve nodal metastasis was found in 76 cases (27.1%, 76/280). In the 979 excised right recurrent nerve nodes, metastases were found in 118 nodes (12.1%). The tumor staging, the total number of involved lymph nodes, vascular invasion, the number of lymph node metastases in the thorax, the number of lymph node metastasis in the abdomen, subcarinal node metastasis, and peri-esophageal lymph node metastasis were independent risk factors of right recurrent nerve node metastasis in esophageal carcinoma.

CONCLUSIONRight recurrent nerve lymph nodes should be dissected in those patients with high risk factors of lymph node metastasis in thoracic esophageal carcinoma.

OBJECTIVETo study the difference of plasma actual bicarbonate between the children with growth hormone deficiency (GHD) and idopathatic short stature (ISS) and to value the plasma bicarbonate standard deviation scores (SDS) in diagnosis of GHD.

METHODSForty-seven short stature children were divided into two groups (GHD and ISS) according to the peak GH response to provocative test. Plasma actual bicarbonate concentrations anion gap (AG), base excess and electrolytes were measured in 47 children with short stature before GH provocative tests.

RESULTSThe mean plasma actual bicarbonate concentrations, bicarbonate SDS were (22.60+/-1.29)mmol/L and -0.27+/-0.98 respectively in GHD children, which were significantly lower than those of ISS children (P<0.01), whereas AG was higher than that of ISS children [(11.73+/-4.52 vs 7.87+/-1.70) mmol/L], P<0.01. Seventy-two percent of patients with bicarbonate SDS

CONCLUSIONPlasma actual bicarbonate concentrations and bicarbonate SDS are lower in patients with GHD than those in patients with idopathatic short stature. Evaluation of plasma bicarbonate SDS of short stature children can predict the probability of GHD, especially when bicarbonate SDS is less than 1 s.
