Regional arterial intra-chemotherapy (RAIC) was an effective method of combined therapy for pancreatic carcinoma, which could elevate the regional con-centration of anticancer agents for sufficient dosage in pan-creas, reduce the systemic adverse events, increase the toler-ation of chemotherapy.It could also increase the concentra-tion of anticancer agents in regional lymph node of pancreas, thus decrease the lymph node metastasis.The mechanism of RAIC for pancreatic cancer and the impact for lymph node metastasis needed to be further investigated.

Objective To investigate the levels of serum neuron-specific enolase (NSE) and C-reactive protein ( CRP ) in patients with acute cerebral infarction, and its value on prognosis. Methods The levels of serum NSE and CRP were compared in 92 acute cerebral infarction patients (observation group) and 45 healthy (control group). The relationship between the levels of NSE, CRP and the degree of neurological damage and infarction location were analyzed. Results The levels of serum NSE and CRP were significantly higher in observation group than those in control group (P< 0.01). In observation group, the levels of serum NSE and CRP were higher in heavy patients [ (35.63 ± 7.12) μg/L, (13.82 ± 3.57) mg/L] than those in mild or medium patients [(17.24 ± 5.32) μg/L, (5.61 ± 2.35) mg/L and (26.08 ±5.91) μg/L, (9.07 ±2.14) mg/L,respectively](P<0.01). There was no significant difference in the levels of serum NSE and CRP in different infarction location(P > 0.05 ). Conclusion The level of serum NSE and CRP is an index in reflecting the degree of neurological damage, and they can be used in evaluating patient's condition and prognosis.

Objective To investigate the accuracy and reliability of the image automatic matching using X-ray volumetric image (ⅩⅥ) system with the accelerator Elekta Synergy and to compare the matches with different methods and area.Methods A simulation plan using the head and neck phantom was designed and sent to ⅩⅥ system for CBCT scanning.During the scanning,the couch for certain distance was moved and the data of ⅩⅥ image automatic Matching in different matching methods and area was collected.Results The result of ⅩⅥ image automatic matching is consistent and correct to direction and distance which the couch had been moved (x:(0.11 ± 0.41) mm,y:(-0.04± 2.6) mm,z:(0.28 ± 0.74 mm)).There are not significant differences between the results that matching in different matching methods and different matching area.Conclusions The automatic image Matching of ⅩⅥ is accuracy and high reliability in recognition of offset error.But there are some significant differences on the automatic image Matching in different matching methods and different matching area.

To investigate the predisposing role of HLA-DR genes to systemic lupus erythematosus (SLE), We used polymerase chain reaction and sequence specific oligonucleotide (PCR/SSO) probe hybridization to type HLA-DR subregion in the patients with SLE of Han nationality from Jiangsu province and matched control subjects. The results indicated that DR2 gene frequency was significantly more frequent in patients than that in controls. Whereas DR4 significantly decreased in patients compared with controls. It suggests that DR2 or the other unidentified genes tightly linked to it might be the susceptible genes of SLE. Whereas DR4 might have a protective effect on SLE.

Objective To explore the feasibility and safety of breast conserving surgery ( BCS) in patients with early breast cancer after local lumpectomy . Methods Clinical data of 26 patients who previously had received local lumpectomy from January 2009 to December 2011 were retrospectively analyzed .All the patients were diagnosed as solitary invasive ductal carcinoma with preoperative staging of T1N0M0.The interval from lumpectomy to BCS was 6-24 days (mean, 10 days) and the maximum diameter of tumors before first operation was 1-2 cm (mean, 1.6 cm).The shortest distance between nipple and operative incision was 2-6 cm (mean, 4.5 cm). Results The operations were successfully completed in all 26 patients, 15 of which received sentinel lymph node biopsy and 11 of which received axillary lymph node dissection .The hospital stay was 3-5 days with stage-Ⅰhealing of incision .All patients received whole breast radiation therapy after BCS .There was no local recurrence or distant metastasis during 2 -5 year ’ s follow-up (median, 32 months).All the patients were satisfied with the shape of breast and the quality of life . Conclusion For those patients with early breast cancer who have received local lumpectomy , meet the requirement of CBS , and have the willing of breast conserving , BCS is an ideal choice after rigid application of surgical indications .

Objective To detect the serum prohibitin protein(PHB)level in children with renal interstitial damage and analyze the correlation between PHB and renal interstitial fibrosis(RIF). Methods Serum PHB protein levels were determined by Western blot analysis in 36 children with kidney diseases,and 30 healthy children were studied as control. Levels of BUN,Scr,and urinary microprotein series(including ALBU/Cr,NAGU/Cr,IgG U/Cr,α1-MU/Cr)were studied by automatic biochemical analyzer. Renal interstitial damage was semiquantitatively graded according to Katafuchi's method. The correlation between serum levels of serum PHB protein and those of BUN,Scr as well as urine microprotein were analyzed. Results Serum PHB protein was positive in children with diverse kidney diseases however it was negative in the normal controls(P ＜ 0.05). Serum PHB levels were significantly higher in children with proliferative glomerulonephritis than those with non-proliferative glomerulonephritis(P ＜ 0.05). Statistical analysis indicated that serum PHB levels positively correlated with the degree of tubulointerstitial lesions(r ＝ 0.868,P ＜ 0.001)as well as the glomerular injuries(r ＝ 0.753,P ＜ 0.001). And,serum PHB levels were also positively correlated with urinary microprotein including NAG(r ＝ 0.586,P ＜ 0.001)and IgG(r ＝ 0.341,P ＜ 0.001). Conclusions Serum PHB levels were significantly increased in children with kidney diseases and were positively correlated with the degrees of renal interstitial damage,suggesting that PHB might be a potential clinical marker for detecting tubulointerstitial lesions.
