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 T cell clonality in patients with systemic lupus erythematosus (SLE) . Methods T cell clonality in peripheral blood lymphocytes from six patients with active SLE was analyzed using reverse transcriptase- polymerase chain reaction (RT- PCR) and GeneScan technique. Results T cell receptor (TCR) Vβ PCR products from two patients were derived from polyclonal T cells, however, TCR Vβ9, Vβ2, VβI, Vβ2 pioducts from the other four patients were derived from oligoclonal T cells respectively.ConclusionT cells from patients with SLE demonstrated a striking oligoclnality and their clonal expansion may be a specific response driven by autoantigens.

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 In order to evaluate the therapeutic effect, to screen effective drugs for AIDS, and to find out the changes of patient's condition, it is necessary to develop an objective method to quantitate the levels of viral load of the patients before and after treatment.Method Differential PCR(D PCR) was used to co amplify the target HIV 1 gag gene and reference template ? globin gene, so as to determine the level of HIV replication quantitatively. The levels of HIV DNA in the peripheral blood mononuclear cells of 8 patients with AIDS were determined quantitatively.Results The levels of the provirus of the 8 patients ranged from 0 508 2 210 copies/?g DNA, there were differences in the levels of replication and integration. Conclusion It is the authors′ opinion that this method is easy to control with an advantage of reliability, quickness and reproducibility, It is suitable to measure clinical specimens, and provides an objective evidence for the evaluation of responses to therapeutic intervention.

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 study the clinicopathological characteristics and prognosis of asymptomatie IgA nephropathy (IgAN) children with pmteinuria and/or microscope haematuria .Methods Clinical and pathological characteristics of 54 children with IgA nephropathy confirmed by renal biopsy were analyzed . These children with IgAN were divided into two groups according to their clinical characteristics at the first onset: asymptomatic IgAN group (AsIgAN) and symptomatic IgAN group (SIgAN) . Histologic changes were classified by Lee SM and Katafuchi semiquantitative scoring system . Results Eighteen children were in AslgAN group and 36 children were in SIgAN group . The degree of proteinuria in SIgAN group [(2 .3±2 .2) g/d] was higher than that in AslgAN group [(0 .4±0 .3) g/d] at the time of biopsy (P＜0 .05) . Although asymptomatic IgAN children were mainly of Lee's type Ⅰ ～Ⅱ, 2 children (11%) were of Lee's type Ⅳ～Ⅴ and 5 cases (27%) presented interstitial injury . Symptomatic IgAN children were mainly of Lee's type Ⅱ ～Ⅲ, there was no significant difference between two groups (P＞0 .05) . Urine micrealbumin was increased in 87% children presented with microscope haematuria . After an average of (26 .9±8 .8)months follow-up, only one case of Lee's Ⅴ progressed into renal failure and the others maintained normal renal function . Conclusions Although children with asymptomatic IgAN have minor clinical symptoms, severe renal pathological lesion and poor prognosis also occur . Urine screening helps to detect renal diseases and renal biopsy should be performed in the patients with increased urine microalbumin .
