Objective To investigate the effect of medium- and long-chain triacylglycerols on body fat accumulation in subjects with different levels of hypertriglyceridemia. Methods 112 subjects with hypertriglyceridemia were randomly divided into two groups: one group was demanded to adopt long-chain triacylglycerol (LCT) oil as their daily use and the other one to medium- and long-chain triacylglycerol (MLCT) oil for consecutive 8 weeks. Anthropometric measurements of body weight, body mass index (BMI), waist circumference (WC), hip circumference(HC), WHR (ratio of WC/HC), triceps skinfold thickness (TSF), subscapular skinfold thickness (SSF), body fat weight, body fat percentage, total fat area, visceral and subcutaneous fat area in abdominal and concentration of blood triglycerides (TG) were measured at the initial and final time of the study. In both groups, the cutpoint of TG 2.3 mmol/L was used to distinguish the different levels of hypertriglyceridemia. Results Compared with LCT group, body weight, BMI, WC, body fat weight, total fat area, visceral and subcutaneous fat area in abdominal in those of TG≤2.3 mmol/L in MLCT group were significantly decreased (P 2.3 mmol/L between the two groups. Furthermore, the concentrations of TG in hypertriglyceridemia subjects of different levels in MLCT group were both significantly lower than those in LCT group after 8 weeks (P 2.3mmol/L.

Objective To study the effect of transsphenoidal approach operation for pituitary adenoma.Methods Transoral and transsphenoidal approach operations were performed in 17 patients with pituitary adenoma,and transnosal and transsphenoidal approach operations were performed in 31 patients with pituitary adenoma,from January 2000 to December 2005.For transoral and transsphenoidal approach operations,the upper lip mucous membrane was opened to introduce into the nasal cavity.For transnosal and transsphenoidal approach operations,the instruments were inserted by way of the right nostril,and the nasal septum was opened.During both of the approaches,a tunnel was established between both sides of the nasal septum,through which the sphenoidal sinus was opened,for entering the sella through the bottom.Results Total resection was completed in 37 patients,subtotal resection was completed in 6,and partial resection,in 5.No surgical-related death occurred.Postoperatively,transient hyperuresis was found in 15 patients,and cerebrospinal fluid rhinorrhea was seen in 7 patients.Seventeen patients were followed for 3～24 months(mean,12 months).Recurrence was encountered in 4 patients at 6 months after operation.Four patients were pregnant and delivered of a child.Conclusions For pituitay adenoma not obviously extending to the parasellar,transsphenoidal approach is a safe and effective option.

Objective To detect the expressions of Wnt2 and dishevelled (Dvl) protein in esophageal squamous carci-noma, and analyze their relationship with the occurrence and development of esophageal squamous cell carcinoma. Meth-ods The expression levels of Wnt2 and Dvl protein were detected by Western blot assay in 60 samples of esophageal carci-noma and adjacent non-carcinomatous esophageal tissues, and their relationship with clinical pathological features were ana-lyzed. Results The relative expression levels of Wnt2 and Dvl protein were higher in esophageal squamous carcinoma tis-sue (0.512 ± 0.406, 1.218±1.082) than those of esophageal tissue adjacent to carcinoma (0.153 ± 0.189, 0.505±0.358). There were significant differences in the expression levels of Wnt2 and Dvl protein between different infiltration depth, different TNM stages, and lymph node metastasis (P<0.01). There was a positive correlation between Wnt2 and Dvl protein in esopha-geal squamous carcinoma (r=0.718, P<0.01). Conclusion The high expression levels of Wnt2 and Dvl protein promote the development and metastasis of esophageal squamous cell carcinomas collaboratively via Wnt2 signal transduction path-ways.

Objective To detect the expression of CD44v5 in esophageal squamous carcinoma (ESCC) and analyze its relationship with clinical pathological features,so as to explore the value of detecting CD44v5 in serum for screening ESCC. Methods The CD44v5mRNA and protein in ESCC tissues and its corresponding adjacent non-carcinomatous tissues were detected by RT-PCR and Western-Blot. Enzyme-linked immunosorbent assay (ELISA) was applied to detect the protein in serum of 100 ESCC patients and 60 healthy subjects. Results (1)The expression of CD44v5 in esophageal squamous carcinoma tissues is higher than the tissue adjacent to carcinoma, and CD44v5 expression in different TNM stages, invasion depth, presence of lymph node metastasis and differentiation is with statistical differences(P < 0.05). (2)CD44v5 proteins in patients with ESCC (31.308 ± 10.123) μg/L is higher than healthy subjects (19.364 ± 1.680) μg/L, the difference is statistically significant (P < 0.01). (3)In the trial of using ELISA method to detect CD44v5 content in serum in the diagnosis of ESCC, the area under the ROC curve is 0.865. If the healthy subjects' serum content of the upper limit of 95%confidence interval was taken as a positive judgment standard, the diagnosis effect: sensitivity is 91.0%and speciality is 60.0%. Conclusion The expression of CD44v5 was related to the occurrence and lymph node metastasis of ESCC. Using ELISA method to detect the contents of CD44v5 proteins in serum, with a high sensitivity, can be used to screen ESCC.

Objective To evaluate the efficacy and safety of infliximab and traditional disease modifying antirheumatic drugs (DMARDs) in the treatment of ankylosing spondylitis (AS). Methods Sixty patients with definite AS were treated with infliximab 5 mg/kg infusion at 0, 2, 6, 12 weeks and were followed up for 12 weeks. The primary endpoint was proportion of ASAS 20 responders at week 12. The secondary endpoints were the proportion of ASAS 50, the change from baseline in Bath AS functional index (BASFI).The improvement of signs and symptoms of AS and physical function were evaluated. The statistical treatments were used t-test andA2 test. Results The proportion of ASAS 20 responders at 2, 6, 12 week was 70%, 83% and 93% respectively. The proportion of ASAS50 responders at patients at 2, 6, 12 week was 13%, 37% and 57% respectively. Results for other secondary efficacy endpoints showed that infliximab could provide substantial benefits to patients with AS by reducing clinical signs and symptoms and improving range of motion, physical function and quality of life. Ten percent of the subjects reported treatment- related adverse events. The most frequently occurred were upper respiratory tract infection, followed by gastrointestinal adverse events and infusion reaction. Most treatment-related adverse events were mild to moderate in severity and disappeared after drug withdrawal. Conclusion Infliximab has been demonstrated to be effective and is well tolerated in the treatment of AS.

Objective To explore the possibility and effectiveness of minimally invasive osteotomy and cable osteosynthesis for the treatment of adolescent eubitus varus. Methods Eleven cases of adolescent cubitus varns(2 cases complicated with internal rotation of 10°)were treated with minimally invasive supracondylar wedged osteotomy to preserve the integrity of the contralateral codex and periosteum.Two screws were inserted above and below the fracture line.They were fixed with cable after the greenstick fracture and internal rotation were adjusted.Plastic bandage was applied for 1 week postoperatively before rehabilitation. Results Bone fractures healed in the 11 cases in 36.3 days averagely,without infection or nerve palsy.Before operation,the mean angles of varus,flexion and extension were 35°±5°,125°±10°and 10°±5°respectively.After a mean follow-up of 33.5 months,the mean valgus angle of the elbow was improved to 8°±2°(t=16.632,P<0.05),flexion to 130°±8°and extension to 8°±3°(P>0.05).Internal rotation deformity was also ameliorated in the 2 cases. Conclusion It is practical and effective to treat adolescent eubitus varus with minimally invasive osteotomy and cable osteosynthesis,for it can lead to stable fixation,short healing time,and does not affect the flexion and extension of the elbow joint.
