The Carneys complex is a multisystemic tumorous disorder that features myxoma(heart, skin, and breast), spotty skin pigmentation(cutaneous and mucocutaneous), endocrine tumors(adrenal, testicular, and pituitary) and peripheral nerve tumors. The criteria far diagnosis of the complex is the presence of two or more of the above conditions. The condition is transmitted as an autosomal dominant trait. The most serious components of the syndrome are cardiac myxoma and psammomatous melanotic schwannoma. The cutaneous manifestations are a major clue in the disorder. We report a case of Carneys complex in a 19-year-old woman. She had spotty pigmentation on her face, left atrial myxoma, and myxoma on her right nipple. Her mother and sister had left atrial myxoma.

Objective:To explore the role of CXCR2 in the invasion and metastasis of head and neck squamous cell carcinoma (HNSCC).Methods:The expression of CXCR2 in HNSCC tissues of 105 cases was detected by immunohistochemical staining,the correlation between CXCR2 expression and cervical lymph node metastases of HNSCC was analysed.Then,3 stable HNSCC cell lines with CXCR2 interference were established,the effects of CXCR2 silencing on cell migration and invasion were observed by in vitro tests.Results:CXCR2 was positively expressed in 51.43% of HNSCC specimens and was statistically associated with the cervical lymph node metastases of HNSCC.CXCR2 silencing markedly inhibited the migration and invasion of HNSCC cells in vitro.Conclu-sion:CXCR2 may play a key role in the invasion and metastases of HNSCC.

Objective To investigate the influence of preterm premature rupture of membranes (PPROM) on neurological development of preterm infants.Methods The preterm infants were classified into 2 groups( PPROM group and control group).The neonatal behavioral neurological assessment (NBNA) and CDCC of infants in two groups were measured and compared after retrieved:gestational age 40 weeks,3 months and 6 months.Results Psycho-moter developmental index(PDI) of PPROM group after retrieved gestational age 3,6 months was significantly lower than that of control group(Pa

ObjectiveTo investigate the clinical efficacy of the fixation of elderly fracture of proximal humerus with locking compression plate(LCP) by mini-incision approach from lateral shoulder.Methods31 elderly patients suffered from elderly fracture of proximal humerus were treated with locking compression plate(LCP) by mini-incision approach from lateral shoulder, male 13 cases, female 18 cases; aged from 56 to 72, average 62-8 years old; fractures according to Neer classification: type Ⅱ(8 cases), type Ⅲ (19 cases), type Ⅳ (4 cases). Cause of injuries: traffic accident (9 cases), falling (20 cases), other injuries(2 cases).ResultsThe patients were followed up 6 to 36 months, an average of about 24 months. Fracture healing time was 2-2 ～ 6-4 months, on average 3-7 months; No wound infection occurred. Post-operative functional score (Neer score) revealed: excellent(18 cases), good (11 cases), fair (2 cases), the ratio of excellent(18 cases), good (11 cases) was 93-5%. ConclusionFixation of elderly fracture of proximal humerus with locking compression plate(LCP) by minimally invasive approach from lateral shoulder is a safe, reliable and minimally invasive procedure with good reduction and stable fixation. Early post-operative functional exercise may be permitted for preventing shoulder joint adhesion.

BACKGROUND: Beta-adrenergic receptor Kinase 1(betaARK1) is a serine/threonine kinase attached, which inhibits the coupling of beta-adrenergic receptor with G-protein. Myocardial betaARK1 level is usually elevated in heart failure and hypertrophy, but it is not known whether the circulating betaARK1 level is related with the degree of cardiac hypertrophy. This study was performed to evaluate the association of the betaARK1 level in circulating mononuclear leukocytes(MNL) in untreated hypertension with left ventricular mass in hypertensive patients. Method: Nineteen non-treated hypertensive patients were included for this study. High blood pressure was confirmed when systolic BP is over 150 mmHg or diastoli BP is over 95 mmHg. Echocardiography was performed to evaluate the degree of hypertrophy by measuring the left ventricular mass index(LVMI) and relative wall thickness(RWT), and test the LV function by measuring the ejection fraction(EF) according to ASE guideline. At the same time, blood was collected from each patient and MNL were isolated by gradient centrifuge with Ficoll-400. Total RNA was purified from MNL and semi-quantitative RT-PCR was performed. After reverse transcription, PCR was done with primers for human betaARK1 and GAPDH as external control. betaARK1 levels were expressed by ratio to GAPDH level and estimated the relations with clinical and Echocardiographic parameters. Result: We studied confirmed 19 hypertensive patients(10 men and 9 women, mean age of 50.6 years). Echocardiographically measured indices(mean+/-SD) were as follows; LVMI(137.3+/-30.6g/m2), PWT(0.53+/-0.09) and EF(54.6+/-8.5%). Ratio of betaARK1 levels to GAPDH was from 0.10 to 0.96 (0.62+/-0.25). betaARK1 levels were correlated with LVMI(correlation coefficient: r=.502, p=.029) and RWT(r=.627, p=.004). But Systolic BP(r=0.009, p=.93), diastolic BP(r=.07, p=.85) or EF(r=.045, p=.84) were not related to level of betaARK1. CONCLUSIONS: The betaARK1 level of circulating MNL was correlated well with the degree of the cardiac hypertrophy estimated by LVMI and RWT. This data suggests that activation of sympatho-adrenal system would exert a major role in developing cardiac hypertrophy and we can expect the decreased responsiveness to catecholamine in the heart of hypertensive patients. betaARK1 in circulating MNL might be used as a predictor or marker for LV hypertrophy in hypertensive patients.

The purpose of this study was to measure the marginal fidelities and the fracture strength of IPS Empress 2. and In-Ceram. ceramic crowns. After constructed of 12 experimental dies for each group, ceramic crowns were fabricated on the metal master dies prepared on the maxillary right premolar. Marginal gaps were measured on the specimen between the margin of each crown and finishing line of the metal master die by using stereo-microscope(SZ-ST. Olympus, Japan) and all specimens were cemented on the metal master die with Bistite II.(Tokuyama soda Co, LTD., Japan) resin cement. Finally, marginal gaps were measured again. To measure of the fracture strength, buccal incline on the functional cusp of specimens were loaded until the catastrophic failure occurred by using the AGS-1000 D.(Shimadzu, Japan). The result of marginal fidelities and fracture strength were statistically analyzed with the SPSS version 8.0 programs. The results of this study were as follows : 1. No significant difference was found in the mean marginal fidelities and fracture strength between the IPS Empress 2. and In-Ceram. 2. In comparison of marginal fidelities between before and after cementation, there was significant difference(P<0.05). The IPS Empress 2 system was shown in this study that had good marginal fidelities and fracture strength compared to In-Ceram ceramics. Although this system was acceptable to clinical applications, the system still has to be considered long-term researches about marginal fidelities and fracture strength due to the lack of data about the clinical researches.

PURPOSE:Ghrelin is an endogenous ligand of the growth hormone secretagogue receptor, and stomach is the major site of ghrelin secretion. The purpose of this study is to compare the serum ghrelin concentrations between patients with type 2 diabetes mellitus (DM) and normal adults. We studied also whether serum ghrelin levels in the patients with type 2 DM are correlated with body mass index (BMI), serum insulin, lipid profiles, and creatinine levels. METHODS:Forty patients with type 2 DM and forty normal adults were included in this study. We measured heights and weights of the subjects and calculated their BMIs. Blood samples were obtained to measure the ghrelin concentration and their sera were stored at -20degreeC until used. In all subjects, serum ghrelin levels were measured using the commercially available Ghrelin(human) EIA kit. RESULTS:No differences of mean values were detected between the control group and the type 2 diabetic group for age, body weight, BMI, and the levels of serum total cholesterol, triglyceride, HDL cholesterol, and creatinine. But ghrelin level of the type 2 diabetic group (71.1+/-30.5 ng/L) was significantly lower than the control group (139.7+/-36.9 ng/L). In the control group, the ghrelin level showed positive correlation with HDL cholesterol (Pearson's correlation coefficient=0.37, P<0.05). In the diabetic group, the ghrelin level showed weakly positive correlation with insulin concentration. However, there was no significant relationship between serum ghrelin and various parameters in the diabetic patients group. CONCLUSION: In this study, ghrelin concentration in type 2 diabetic patients was lower than that in the control group. In the control group, serum ghrelin concentrations were positively correlated with HDL cholesterol. In the type 2 diabetic group, there was no significant correlation between insulin and ghrelin concentrations.

Aim To investigate the protective effects of chrysophanol( Chry) on immune function of lead poi-soning mice. Methods The lead poisoning model was established by peritoneally injecting mice with 7 mg · kg-1 lead acetate every day for 8 days. After Chry was ip injected for 14 days,spleen and thymus index, the white blood cell count, T, B lymphocyte proliferation, phagocytic function of macrophages, natural killer cell ( NK cell) activity were detected. The concentrations of IFN-γ,IL-2,IL-4,IL-10 in the lead poisoning mice ser-um were determined by enzyme-linked immunosorbent assay ( ELISA) . Results Intraperitoneal injection of 7 mg · kg-1 lead acetate for 8 consecutive days could cause an immunity decline in lead poisoning mice, Chry could significantly improve the immunity of lead poisoning mice. Compared with model group, Chry sig-nificantly improved growth rate, viscera index and white blood cell count of lead poisoning mice at differ-ent extent ( P<0 . 05 or P<0. 01 ) . Chry ( 1 . 0 ,10 . 0 mg·kg-1 ) significantly increased the B,T lymphocyte proliferation ( P<0 . 01 ) and the phagocytosis of macro-phage and NK cell activity ( P <0 . 01 ) . Compared with the control group, the concentrations of IFN-γ, IL-2 , IL-4 , IL-10 of lead poisoning mice serum were significantly reduced ( P <0 . 01 ) . Compared with the model group, Chry (1. 0、10. 0 mg·kg-1 ) significant-ly increased the concentrations of IFN-γ, IL-2 , IL-4 , IL-10 ( P <0. 01 ) , while there were no significant changes in (0. 1 mg·kg-1 ) concentrations of IFN-γ, IL-2 , IL-4 in Chry ( 0 . 1 mg · kg-1 ) treatment group ( P>0. 05 ) , only IL-10 was significantly increased in Chry ( 0 . 1 mg · kg-1 ) treatment group ( P<0 . 05 ) . Conclusion Chry can significantly improve the im-mune function of lead poisoning mice.

Multiple fixation techniques for arthrodesis of the ankle and hindfoot have been introduced. The cannulated screw fixation provides excellent internal compression for arthrodesis. We used 5.0 and 6.5mm cannulated screws for seven ankle, seven subtalar, four tibiotalocalcaneal, three pantalar and two triple arthrodesis between January 1994 and September 1995. No iliac bone graft was utilized. The follow-up period was from 12 to 25 months. Ages of the patients ranged from 25 to 58 years. All fused except one who was preoperatively diagnosed as pyogenic arthritis of the ankle and hindfoot. One patient with diagnosis of Streeter's disease was complicated with partial necrosis of the forefoot. We think this procedure has several advantages; 1. The leg or foot length is largely preserved because minimal subchondral bone is removed. So, the leg and foot is aesthetically pleasing and the musculature around the ankle and foot can be maintained in the normal balanced position. 2. The rate of fusion is high, because the soft tissues are minimally stripped and cannulated screw compresses the subchondral bone surface. 3. The cannulated screws rarely requires removal. So, we believe that the cannulated screw fixation for the ankle and hindfoot arthrodesis is an excellent treatment method.
