Objective To investigate the expression of transforming growth factor?1(TGF-?1)in human colorectal carcinoma and its value for predicting the prognosis.Methods The expression of TGF-?1 and vascular endothelial growth factor(VEGF)was measured in specimens of 52 coloreetal cancers by immunohistoehemistry.The features of clinical pathology were analyzed and the follow-up of all patients were conducted.The correlation between the expression of TGF-?1 and the survival time was studied with Log-rank test.Results Of 52 patients,no expression of TGF-?1 and VEGF was observed in 11 and 14 patients,and the expression was noticed in 41 and 38 patients,respectively.There was a signifi- cant positive correlation between expression of TGF-?1 and expression of VEGF(x~2＝0.633,P＜0.01). Furthermore,the expression of TGF-?1 was significantly correlated with Dukes staging(x~2＝19.866,P＜0.01)and metastasis of lymph nodes(x~2＝13.152,P＜0.01).The 3-year overall survival rates(OSR)in all patients was 49.1% and the 3-year OSR of patients with and without expression of TGF-?1 were 20.5% and 69.2% respectively(x~2＝11.64,P＝0.0006).Conclusion The expression of TGF-?1 could be served as an important predicator for prognosis of coloreetal carcinoma.

OBJECTIVETo observe the effect of nourishing Yin, strengthening Qi and activating blood decoction on Fas/FasL in salivary glands of NOD mice with Sjogren's syndrome and their mRNA expression.

METHODThirty-two NOD mice were randomly divided into the model group, the traditional Chinese medicine group (TCM group, orally given 0.4 mL nourishing Yin, strengthening Qi and activating blood decoction as per 100 g x kg(-1) everyday), the hydroxychloroquine group (given 0.4 mL hydroxychloroquine as per 60 mg x kg(-1) everyday), the traditional Chinese medicine and western medicine group (TCM WM group, given nourishing Yin, Strengthening Qi and activating blood decoction 50 g x kg(-1) and hydroxychloroquine 60 mg x kg(-1), 0.4 mL everyday), with eight mice in each group. Eight Balb/C mice were selected as the normal control group (normal group). All of mice were killed after eight weeks, and their submaxillary glands were dissected. The expression levels of Fas/FasL were examined by immunohistochemical method, and the FasL mRNA was detected by RT-PCR.

RESULTThe expression levels of Fas/FasL in salivary glands of the model group were higher than that of other groups (P < 0.05). The expression level of FasL of the normal group was much lower than that in the hydroxychloroquine group (P < 0.05). The relative expression level of Fas mRNA in salivary glands of the model group was higher than that in other groups, but the control group was notably lower than other groups (P < 0.05). The expression level of FasL mRNA in salivary glands of the model group was higher than that in TCM and TCM WM groups (P < 0.05). But the expression level in TCM WM group was notably lower than the hydroxychloroquine group (P < 0.05).

CONCLUSIONThe nourishing Yin, strengthening Qi and activating blood decoction could down-regulate the expression level of Fas/FasL in salivary glands of NOD mice with Sjogren's syndrome and their mRNA expression, and had a better efficacy after being combined with hydroxychloroquine. The nourishing Yin, strengthening Qi and activating blood decoction might treat the Sjogren's Syndrome by reducing apoptosis which is regulated by Fas/FasL

Objective To evaluate the efficacy of radiosynovectomy with 32P colloid in haemophilic synovitis of adolescents. MethodsRadiosynovectomy with 32P colloid was primary performed on 26 male haemophilic patients(26 joints),whose average age was 16 years(11 to 21 years).The average dose of 32P colloid was 2.1 mCi(1.0 to 3.0 mCi). Results After 6-month interval,haemarthrosis was reduced by no less than 30% in 23 patients,with a total efficacy of 88.5%.The mean frequency of haemarthrosis was reduced from 1.9 per month of presynovectomy to 0.3 per month of postsynovectomy(P

To investigate the safety and efficacy of capsular tension ring ( CTR ) insertion combined with phacoemulsification and intraocular lens ( lOL ) implantation in patient with pseudoexfoliation syndrome after anti-glaucoma surgery.
●METHODS: A retrospective study was conducted of 10 eyes from 10 cataract patients with pseudoexfoliation syndrome following trabeculectomy surgery, and who underwent CTR insertion combined with phacoemulsification and lOL implantation between January, 2012 and June, 2013. All cases had nuclear cataracts ( nuclear hardness Ⅱ 1 eye, nuclear hardnessⅢ 4 eyes, nuclear hardness Ⅳ 5 eyes). One case with Ⅳ nuclear hardness cataract had iridodonesis and lens subluxation. Postoperative visual acuity, intra- and post-operative complications, anterior capsular opening, lOL position, and postoperative intraocular pressure ( lOP) were assessed. Follow-ups ranged from 3 to 14mo. The t test was used to analyze the variables studied.
●RESULTS: All patients had a successful CTR insertion combined with phacoemulsification and lOL implantation. A modified CTR insertion was performed in one case, the others underwent a standard CTR insertion. The best corrected visual acuity ( BCVA) was≥0. 5 in 3 eyes and 0. 3-<0. 5 in 2 eyes. However, BCVA was ≤0. 1 in 5 eyes. No decentration and dislocation of lOL was found during follow - up. Optic atrophy of different level could be found in all cases. The mean lOP was 16. 78±2. 48mmHg before surgery. And the average lOP is 16. 01±2. 33mmHg at 3mo postoperative (t= 1. 9955, P>0. 05). The most common intrao- and post-operative complications were corneal edema, small pupil, residual cortex, spontaneous zonular dialysis.
● CONCLUSlON: Suitable CTR insertion in appropriate occasion may be beneficial to patients with pseudoexfoliation syndrome after trabeculectomy during cataract surgery. lt prevents the lOL decentration and decrease the surgical complication. Less complication occurs at the early stage.

METHODS: Block design, prospective study. 60 cataract patients (60 eyes) were selected, which divided into two groups according to the age, young age group (group A, 20 eyes of 20 patients) and older age group (group B, 40 eyes of 40 patients). Two groups were all given compound tropicamide eye drops for fully mydriasis before operation, computer software to process images during operation, and according to the cornea amplification ratio measure pupil diameter during the operation phase: before the corneal tunnel incision ( t1 ) , after injection of sodium hyalurantae ( t2 ) , before artificial lens implantation (t3), at the end of the surgery ( t4 ). Statistical analysis of data using SPSS18. 0 software.RESULTS: The pupil diameter measurements of t1-t4 were followed respectively:group A were 8. 36 ± 0. 65, 8. 97±0. 50, 8. 67±0. 63, 8. 72±0. 96mm; group B were 7. 73± 0. 58, 8. 23 ± 0. 59, 7. 89 ± 0. 16, 7. 70 ± 0. 63mm. Overall comparisons between the two groups, the pupil diameter measurements had differences during the operation phase ( F = 26. 696, P< 0. 05 ). Comparisons between the two groups at different time points: the pupil diameter of t1-t4 in group A was larger than that in group B, with statistically differences (P<0. 05). The pupil diameter of each groups had a tendency to change in different operation phrases, with no statistically differences (F=2. 617,P>0. 05). Comparisons in a group at different time points: the pupil diameter of t2 was larger than that in t1, with statistically differences ( P>0. 05), the pupil diameter of t3 and t4 were decreased in group B, with statistically differences (P<0. 05).CONCLUSlON: Compound tropicamide eye drops are given for mydriasis before operation, young patients with cataract and senile patients with cataract can achieve the effect of surgery for mydriasis, the pupil stability of phacoemulsification in senile patients with cataract are lower than that in young patients with cataract.

OBJECTIVETo analyze the clinical effect and related risk factors of Gartland type II-III supracondylar fractures of humerus in children in the emergency closed reduction and percutaneous Kirschner wire fixation.

METHODSFrom January 2008 to June 2013,112 children of Gartland type II to III supracondylar humeral fractures were treated in children in emergency closed reduction and percutaneous K-wire fixation, including 72 males and 40 females with an average age of 6.2 years old ranging from 2 to 11 years old. Among them,74 cases were in Gartland type II fractures,38 cases were in type III; The duration from injury to surgery time was 2.5 to 8 hours (averaged 4.6 hours). Elbow cast was applied after operation with the elbow extended of 100 degrees for 4 to 6 weeks, then the gypsum and Kirschner wires were removed.

Objective To investigate the expression and relationship between Phosphatase and tension homolog deleted on chromosome ten (PTEN) and Alpha fetoprotein(AFP) in hepatocellular carcinoma. Methods PTEN and AFP expression was examined by immunohistochemical method. Results PTEN expression was significantly weaker in patients with tumor less than 5.0 cm and patients with CLIP score≥1 (P<0.05). The expression of PTEN and AFP was negatively correlated ( Rs=-0.422, P=0.043), serum AFP and tissue expression of AFP was positively correlated (Rs=0.380, P=0.042), but for individual expression was not consistent. Conclusions PTEN and AFP is respectively negative and positive adjustment factor of PI3K/AKT pathway. Tissue expression of AFP may be more significant, and may become the new targets for the treatment of hepatocellular carcinoma.
