Objective To investigate the role of sLOX?1 and leptin in metabolic syndrome ,glucose and lipid metabolism. Methods 58 patients with metabolic syndrome were included in the study ,with other 35 normal controls as control group. Fasting venous blood samples were collected. ELISA method was used to detect serum sLOX?1 and leptin levels. The related biochemical indicators were tested. Results The sLOX?1 and leptin levels in the metabolic syndrome group were significantly higher than those in the control group(P < 0.01). The levels of sLOX?1 and leptin were further compared between different genders. The differences were not statistically significant (P > 0.05). sLOX?1 and leptin levels were positively correlated. They were positively correlated with WAIST,TG,SBP,DBP,and negatively correlated with HDL?C. Leptin and age,FPG also had positive correlation,but sLOX?1 was not correlated with age and FPG. Conclusion sLOX?1 may be able to predict endothelial damage in patients with metabolic syndrome in an early stage. Combined with leptin ,the endothelial dysfunction could be reflected more accurately. They may be the important factors for early diagnosis and risk assessment of metabolic syndrome.

Objective It is thought that environmental agents, especially the diet, play an important role in the processes of gastric cancer. The study was designed to investigate the relationship between dietary factors and the risk of gastric cancer in residents of islands so as to offer the evidence for effective measures of prevention and control. Methods A frequency matched design of case control study was used. 103 cases of gastric cancer newly diagnosed in 2001 and 133 controls were randomly selected among the residents of islands. And dietary factors were further investigated. Adjusted odds ratios (OR) and 95% confidence intervals (CI) of dietary factors on the processes of gastric cancer were estimated using unconditional logistic regression models. Results After the correction of the effects of some non diet factors, increased risks of gastric cancer were associated with hot diet (OR=1.48,95%CI:1.03 2.14) and pickled food (OR=2.63,95%CI:1.74 3.98). An inversed association with the risk of gastric cancer was seen in sauting (OR=0.33,95%CI:0.13 0.83 ), food eaten at regular time (OR=0.29,95%CI:0.19 0.44), allium vegetables (OR=0.43,95%CI:0.22 0.82) and carrot (OR=0.10,95%CI:0.02 0.41). Furthermore, PARc% of hot diet and pickled food were 11.8% and 57.8% respectively, which suggested that the carcinogenic effect of hot diet and pickled food on stomach in the population reached about 70% after the correction of the effect of other factors.Conclusions Pickled food and hot diet as the habits of residents in Zhoushan islands are important risk factors for gastric cancer, while decreased risk effect is found in sauting food, having regular dietary time and frequently eating allium vegetables and carrot.

Objective Investigated the clinical features and risk factors of pulmonary metastasis in children with papillary thyroid carcinoma aiming to provide guide for clinical work.Methods Collected the informations of 40 patients with under the age of 14,who underwent surgery in the Thyroid surgery of the First Affiliated Hospital of ZhengZhou University and confirmed for the papillary thyroid carcinoma by the postoperative pathology.At the same time,excluded studies with history of head and neck malignancy or lyphoma or secondary thyroid cancer,papillary thyroid carcinoma with hyperthyroidism and cases of imcomplete informations.The age of the 40 patients was 3 to 14 years old,12 were boy and 28 were girl.The largest tumor diameter was 7.5 cm,and the smallest was 0.3 cm.Tumor lesions were solitary in 22 cases and multiple lesions were in 18 cases.There were 33 cases of cervical lymph node metastases and 7 cases of no cervical lymph nodes.There were 10 cases of pulmonary metastasis and 30 cases of non-pulmonary metastasis.This research adopted chi-square test and Logistic regression statistical analysis of related risk factors and clinical features,including patients' age,gender,tumor diameter,number of lesions,surgical methods,neck lymph node metastasis,and pulmonary metastasis.Results The positive rate of plumonary metastsis in children with papillary thyroid carcinoma was 25％ (10/40),statistical analysis found that the positive rate of children with lung metastasis (x2 =8.620,P =0.003),tumor diameter over 2 cm (x2 =5.763,P =5.763) and the difference was statistically significant higher.Logistic regression analysis showed that the number of risk factors was multifocal papillary thyroid carcinoma in children lung metastasis (OR =13.058,P =0.028).Conclusions Higher lung metastasis is a clinical feature of thyroid papillary carcinoma in children.The risk of lung metastasis was significantly higher for children with thyroid papillary carcinoma who had multiple lessions.

Objective To evaluate the diagnosis and surgical treatment of primary hyperparathyroidism (PHPT). Methods 53 patients with PHPT who were treated in our hospital from 1997 to 2009 were analyzed retrospectively. Results All patients showed hypercalcemia and elevated parathyroid hormone (PTH). Among them, 43 were diagnosed as parathyroid adenoma, 6 were parathyroid hyperplasia and 4 were parathyroid cancer.The accuracy rate of parathyroid tumor localization was above 94. 3%. All patients presented temporary hypocalcemia after surgery. Conclusions Parathyroidectomy is an effective approach for patients with PHPT. Preoperative localization is essential to the surgery.

Papillary thyroid microcarcinoma (PTMC) is a subtype of papillary thyroid cancer,and there are many debates about its treatments,including extent of thyroidectomy,necessity of prophylactic central-neck nodal dissection,risk-benefit ratio of thyroid-stimulating hormone suppression and indications of observation therapy,et al.The epidemiology and treatment programs of thyroid PTMC were reviewed in this article.

Objective To observe the effect of intra-articular injection of sodium hyaluronate (Na-HA) on mRNA expression of inducible nitric oxide synthase (iNOS) in cartilage of osteoarthritis (OA). Methods Sixteen white rabbits were underwent unilateral anterior cruciate ligament transection and were divided into 2 groups randomly 5 weeks after transection. Experimental group rabbits received 0.3 ml of intra-articular 1% Na-HA injection once a week. Animals in control group were treated with the same conditions using normal saline. All animals were sacrificed 10 weeks following surgery. The aritcular cartilage degeneration of medial femoral condyle was evaluated at mascroscopically and microscopically. The mRNA expression of iNOS in cartilages was analyzed by reverse transcription-polymerase chain reaction (RT-PCR). Results Cartilage degradation in experimental group was significantly less severe than that in control group. No significant difference of iNOS mRNA expression in cartilage was found between the experimental group and the control group. Conclusion Na-HA can significantly reduce the severity of cartilage degradation of OA. Na-HA dose not show definite effect on iNOS expression in cartilage during early stage of OA.
