BACKGROUND:The early damaged chondrocytes are susceptible to de-differentiate and exert unstable phenotype during the in vitro culture, thus needing some growth factors.
OBJECTIVE:To observe the promotion effect of insulin-like growth factor 1 on the in vitro proliferation of chondrocytes in adult rabbits with traumatic arthritis.
METHODS:Traumatic arthritis models of adult rabbits were established by using the modified Hulth method. After the models were successful y established, the distal femur and proximal tibia were harvested under sterile conditions, the chondrocytes were cultured. The cultured cells were divided into two groups:control group was cultured with Dulbecco’s modified Eagle’s medium containing 10%fetal bovine serum, while experimental group was cultured with Dulbecco's modified Eagle’s medium containing 100μg/L insulin-like growth factor 1. The effect of insulin-like growth factor 1 on the proliferation of chondrocytes in adult rabbits with traumatic arthritis was determined through the cytomorphology, cellcounting, and cellactivity.
RESULTS AND CONCLUSION:The chondrocytes in adult rabbits with traumatic arthritis were successful y cultured, the majority of cells were mini-cells, presenting smal fusiform, round or polygonal shape. Hematoxylin-eosin staining showed that the number of cells in experimental group was higher than that in control group. MTT assay found that the absorbance of cells in experimental group was greater than that in control group (P<0.01). Our findings indicate that, insulin-like growth factor 1 can promote the in vitro proliferation of chondrocytes in adult rabbits with traumatic arthritis.

Objective To explore the difference of four calculating methods used to determine the obesity. Methods Two thousand four hundred and forty six (2446) men and three hundred and seventy nine (379) women were measured height and body mass, Standard body mass, BMI, body fat ratio and obesity index(OI) were calculated with formula. According to the BMI≥ 25 kg/m2 , BMI ≥ 27 kg/m2 and BMI≥28 kg/m2, the obese adults were 1419,680 and 435 respectively;there were 649 adults that their body mass was over 20％standard body mass; there were 639 adults that their body fat ratio was over 25％(male)and 33％(female). Results For obesity determination, the adults who were 20％overweight and over standard body fat ratio were significantly different from those whose BMI were over 25 kg/m2 ( P＜0. 05 ) ;Those who were 20％overweight and over standard body fat ratio were not significantly different from those whose BMI were over 27 kg/m2 ( P＞0.05 ) ; Those who were 20％overweight and over standard body fat ratio were significantly different from those whose BMI were over 28 kg/m2 ( P＜0. 05 ). Conclusion Determining obesity with BMI≥27 kg/m2 is feasible and rational.

Objective To raise the awareness of adrenal Castleman′s disease by analyzing the clinical features and management of a patient with adrenal Castleman′s disease. Methods A case of adrenal Castleman′s disease of our hospital was retrospectively analyzed, including clinical feature, laboratory findings, pathology, treatment, and follow-up. All the data and pertinent literatures were reviewed and analyzed. Results An incidentaloma measuring 4. 8 cm × 6. 3 cm in the right adrenal gland was observed in a 30-year-old men in a ultrasonography examination performed due to a medical check-up. Laboratory analysis showed that the lesion was not hyperfunctioning. The patient subsequently underwent an exploratory laparotomy. Pathological examination revealed retroperitoneally localized Castleman′s disease of the hyaline vascular type. Conclusion Adrenal Castleman′s disease is a rare cause of lymph node hypertrophy, and it is necessary to keep in mind the possibility of its occurrence and take it into consideration in the differential diagnosis of any solitary, heterogeneous, and hypervascular retroperitoneal mass. The proper cooperation between the clinician and pathologist allows early diagnosis and suitable therapy.

OBJECTIVE: To observe the protective effects of Yanggan Lidan Granules (YGLDG) on carbon tetrachloride (CCl(4))-induced liver damage in mice and to find out its mechanism. METHODS: A model of chronic liver damage was established in mice by intraperitoneal injection of CCl(4). After three weeks, those model mice were treated with low-, medium-, high-dose YGLDG, Danning Tablets and bifendate respectively for four weeks. Then the levels of serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST), as well as the contents of superoxide dismutase (SOD) and malondialdehyde (MDA) in liver tissues were detected. RESULTS: YGLDG could significantly reduce the levels of serum ALT and AST in model mice, and the content of MDA was obviously decreased while the content of SOD was increased in liver tissue. CONCLUSION: The therapeutic effect of YGLDG on mice with CCl(4)-induced liver damage is to relieve the seriousness of liver damage, and its mechanism may relate to reducing peroxidation activity in liver tissue.

As there is widely application in clinical diagnosis and treatment with complete blood count(CBC)and differential count(DC),the experts of clinical hematology laboratory in the word have paid highly attention to the review of CBC and DC.In this paper,we would like to have an introduction for the suggested criteria for action following automated CBC and WBC differential analysis obtained from The International Consensus Group for Hematology Review and Clinical and Laboratory Standards Institute (CLSI).

Objective To investigate the changes of serum N-terminal-pro-B-type natriuretic peptide (NT-proBNP) concentration in patients with Graves' disease (GD) and its clinical significance. Methods Two hundred and sixty-nine patients with GD were enrolled in this study. Serum concentrations of thyroid hormones,TRAb, and NT-proBNP were measured. Results Serum NT-proBNP levels were positively associated with FT3(r=0.260, P<0.01), FT4(r=0.297,P<0.01) and heart rate (r=0.251, P<0.05) independent of age,sex and body mass index (BMI). The difference of serum NT-proBNP concentrations between newly-onset and treated patients existed (P<0.01) after the adjustment for thyroid hormone levels, age, sex and BMI. Serum FT4level exerted a significant impact on NT-proBNP level (P <0.01). Serum NT-proBNP increased even in patients with controlled thyroid function. Conclusion Serum NT-proBNP level in patients with GD increases with elevation of FT4 independent of sex, age and BMI. The measurement of serum NT-proBNP concentration appears to be helpful to monitor the alteration of vascular stiffness and fluid volume in GD patients, and may provide useful evidence for early intervention of cardiovascular disease induced by hyperthyroidism.

Objective To indentify the gene mutation of fibroblast growth factor receptor 3 (FGFR3) gene in a Chinese family with congenital achondroplasia (ACH). Methods The genomic DNA from 2 clinically diagnosed ACH patients and the other 4 members from the same family was prepared for PCR. The products of PCR were purified and then sequenced directly. Results Two patients with ACH in this family showed G-A transition mutation at nucleotide 1138 as heterozygotes. Conclusion The G-A transition mutation at nucleotide 1138 in transmembrane domain of FGFR3 gene seems to be the pathologic cause of this Chinese family with ACH.
