This article is to report 32 pathologically proved cases of primary non-Hodg-kin's malignant lymphoma of the gastrointestinal tract including 9 cases in the stomach, 10 in the small intestines, 9 in the ileocecal region, and 4 in the large intestines. 22 patients were male and 10 female. The highest incidence occurred in the age group from 20 to 30- The main symptoms are abdominal pain( 30/32), intraabdominal mass (14/32), vomiting(6/32), and gastrointestinal bleeding (5/32).All the cases except one were of the diffuse type histologically. Analysis of the follow-up data of 24 cases found that the infiltration of the tumor cells into the deeper layers of the gastrointestinal walls and the occurrence of tumors in the small and large intestines were usually associated with poor prognosis. The criteria of diagnosis and differential diagnosis of this disease were briefly discussed.

Objective To explore the expression level of CD4+ CD25+ CD127low-regulatory T cells (Treg) in the peripheral blood of hepatitis B virus (HBV)-infected individuals,and its association with liver pathology.Methods Thirty-five HBV-infected individuals and 20 healthy controls were enrolled.The frequencies of peripheral blood CD4+ CD25+ CD127low/-Treg were detected by flow cytometry.HBV-related serological tests as well as ultrasound-guided liver biopsies were performed in HBV-infected individuals.The two groups were compared by t test.Spearman and Pearson correlation analyses were performed.Results The alanine aminotransferase (ALT) level of HBV-infected individuals was (34.57 ± 15.36) U/L,with 25 subjects of ALT＜40 U/L.Twenty subjects were hepatitis B e antigen (HBeAg) positive,and 15 were HBeAg negative.The frequency of the peripheral blood CD4+ CD25+ CD127low/-Treg in HBV-infected individuals was (5.59 ±1.50)％,which was significantly higher than that in healthy controls [(4.85±0.95) ％ ; t=2.191,P=0.033].The level of peripheral blood CD4+ CD25-CD127low/-Treg was positively correlated with HBV viral load (r=0.495,P=0.003).Thirty-one subjects had liver inflammatory score ≤2,with a peripheral blood CD4+ CD25+ CD127low/-Treg level of (5.80 ± 1.44) ％,which was significantly higher than that of the rest 4 subjects who had liver inflammatory score ＞2 [(4.00±0.77)％; t=2.425,P=0.021].Twenty-four subjects had liver fibrosis score ＜2,with a peripheral blood CD4+ CD25+ CD127low/-Treg level of (6.00±1.44) ％,which was significantly higher than that of the rest 11 subjects who had liver fibrosis score ≥ 2 [(4.70 ± 1.24)％; t =2.559,P＝0.015].The expression of CD4 + CD25 +CD127low/-Treg in peripheral blood was inversely correlated with liver inflammation (r=-0.539,P=0.001) and fibrosis (r =-0.488,P =0.003) in HBV-infected individuals.Conclusions CD4+ CD25+ CD127low/-Treg is associated with chronic condition and liver damage of hepatitis B.It may play an important role in occurrence,development and prognosis of the disease.

Objective To observe the effect of plasma exchange (PE)therapy for removing serum interleukin-6 (IL-6),tumor necrosis factor alpha (TNFα),and interferon gamma (IFNγ)in patients with liver failure,and to assess the value of artificial liver support system in the treatment of liver failure.Methods The study included 36 patients with liver failure who were hospitalized in the First Affiliated Hospi-tal of Bengbu Medical College from February 2012 to February 2013.Blood samples were collected before PE and the next morning after mul-tiple treatments.Plasma TNFα,IL-6,and IFNγlevels were measured by ELISA.Between-group comparison of measurement data before and after treatment was made by independent-samples t test,and comparison of mean values between groups was made by analysis of vari-ance.Results All the 36 liver failure patients had significantly lower levels of TNFα(381.23 ±190.57 ng/L vs 274.12 ±212.30 ng/L,P<0.05),IL-6 (77.9 ±83.09 ng/L vs 54.8 ±63.32 ng/L,P<0.05),and IFNγ(534.65 ±471.19 ng/L vs 259.65 ±312.26 ng/L,P<0.05)after treatment than before treatment.According to the severity of clinical manifestations,the patients with subacute or acute-on-chronic (subacute)liver failure were divided into early stage,middle stage,and advanced stage groups.There were significant differ-ences in IL-6 and TNFαdecreases between the early stage,middle stage,and advanced stage groups (P<0.05).IFNγdecrease signifi-cantly differed between the early stage or middle stage group and advanced stage group (P<0.05),but not between the former two groups (P>0.05).After PE therapy,29 out of 36 liver failure patients recovered well,while the remaining 7 patients deteriorated.The recovered group had significantly greater decreases in TNFα(122.58 ±57.64 ng/L vs 42.45 ±19.86 ng/L,P<0.05),IL-6 (26.93 ±7.25 ng/L vs 6.71 ±3.55 ng/L,P<0.05),and IFNγ(284.06 ±94.31 ng/L vs 217.47 ±45.76 ng/L,P<0.05)than the deteriorated group.The response rates of patients with acute,subacute,acute -on -chronic,and chronic liver failure were 66.67%,85.71%,86.36%,and 50%,respectively.Conclusion Continuous artificial liver PE therapy can effectively remove pro-inflammatory cytokines from plasma and thus improve the clinical outcomes of patients with liver failure.

Objective To investigate the expressions of epidermal growth factor receptor (EGFR), cyclooxygenase-2 (COX-2) and P63 protein in non-small cell lung cancer (NSCLC) and their relationship with TNM staging and lymph node metastasis of NSCLC. Methods Seventy-eight paraffin-embedded specimens of NSCLC from 1998-2005 were collected in this study. Inclusion criteria included no chemotherapy or radiotherapy before operation. Pathological diagnosis was made after operation: 43 squamous carcinoma and 35 adenocarcinoma, 45 with lymph node metastasis and 33 without, 13 in stage Ⅰ, 19 in stage Ⅱ, 28 in stage Ⅲ and 18 in stage Ⅳ. The expressions of EGFR, COX-2 and P63 were determined by immunohistochemical staining (S-P). Results The expression rates of EGFR, COX-2 and P63 were 65.4% (51/78), 61.5% (48/78) and 56.4% (44/78) respectively in 78 cases of NSCLC. Significant difference in the expressions of COX-2 and P63 was found between squamous carcinoma and adenocarcinoma (P0.05). The positive rate of EGFR and COX-2 protein expressions in NSCLC of stage Ⅲ-Ⅳ and NSCLC with lymph node metastasis was significantly higher than that in stage Ⅰ-Ⅱ and NSCLC without lymph node metastasis (P0.05). Conclusion Over-expressions of EGFR and COX-2 may play an important role in invasion and metastasis of NSCLC. COX-2 and P63 may be valuable markers in differentiating pulmonary squamous cell carcinoma from pulmonary adenocarcinoma.

Objective To explore the effects of ultraviolet, magnetic field and drug therapy on chemotherapeutic phlebitis(CP) in rabbits. Methods CP models were established by injecting vinorelbine into ear-edge veins of rabbits, and resulting in red swelling and fever of the skin. Twelve Japanese albino rabbits were randomly divided into four groups: a control group(C group), an ultraviolet therapy group (UT group), a magnetic field therapy group (MF group) and a drug group (D group). Twenty-four rabbit ears were observed by use of naked eyes and pathohistological examination after correspond treatment. Results Compared with those in C group, inflammation symptoms and edema in UT and MF groups were mitigated significantly by using of naked eyes and pathohistological examination (P 0.05) . In addition, the effects of inhibiting fibrous tissue hyperplasia were observed in magnetic field group (P

OBJECTIVE To investigate the status of traumatic infection among earthquake in order to provide reasonable evidence for anti-infective therapy. METHODS Samples were collected from 14 patients with compound fracture or osteofascial compartment syndrome for bacterial,fungal and anaerobic culturing,then according to pathogens to choose antimicrobial susceptibility test (AST). RESULTS Among 14 victims,10 had germ growth in wound secretions,the infection rate was 71.43%. Among 17 samples the bacteria,fungi and anaerobic were isolated in 12,4 and (samples,respectively),the isolated rates were 70.59%,23.53% and 5.89%. The main pathogens for the first culture were Enterobacter cloacae,coagulase negative Staphylococcus (CNS) and Acinetobacter. The Clostridium tetani and C. perfringens were all negative. We also isolated 5 strains of fungi from them 1 strain of Candida. CONCLUSIONS Most of the victims from disaster area have got bacterial infection. Most of them are combined infection,some of the infections are nosocomial infections. The key points of the treatment are to find pathogens immediately and choose a reasonable antibacterial agents according to the AST.

Objective To compare the clinical value of injury severity score (ISS) and CRAMS (circulation,respiration,abdomen,motor,speech) score in the prognosis of patients with severe multiple trauma in emergency department.Methods A total of 93 severe multiple trauma patients with 69 male and 24 female and age ranged from 21 to78 years with mean age (43.4 ± 14) years admitted in the emergency department from March 2014 to December 2015 were enrolled into this study.All of them were evaluated by using ISS and CRAMS score respectively and their survival during hospitalization was observed.Then,the predictive capabilities of ISS and CRAMS score for the mortality of patients were assessed by using receiver operator characteristic (ROC) curves.Results The mean ISS was (25.59 ± 5.37) and mean CRAMS score was (6.75 ± 1.26) in 93 patients with severe multiple trauma.Compared with the survival group (n =75),the ISS in the death group (n =18) was significantly higher (t =7.13,P ＜0.01) and CRAMS score was significantly lower (t =-6.03,P ＜0.01).In the ROC curve analysis,the AUCROC of predicting mortality of multiple trauma patients by ISS score was 0.897 and CRAMS score was 0.891,respectively.There was no significant difference in accuracy of predicting mortality between the two scoring systems (Z =0.718,P ＞ 0.05).When the death was chosen as the prediction target,the optimal cut-off point for ISS was 27 and CRAMS score was 6,respectively.Conclusions CRAMS score in comparison with ISS score has the likewise predictive value for the prognosis of severe multiple trauma patients in emergency department.However,the CRAMS score is simple and easy in practice.The changes of CRAMS score demonstrate the severity of trauma timely and reliably,which is in favor of the diagnosis and treatment of hospitalized trauma patients in early stage.

Objective To observe the value of contrast-enhanced ultrasound (CEUS) in the evaluation of efficacy of Argon-Helium cryoablation therapy for liver malignancies.Methods A total of 27 patients with 27 lesions of liver malignancies underwent ultrasound-guided Argon-Helium cryoablation therapy.CEUS was used to evaluate the local response and compared with contrast-enhanced CT (CECT).Results One month after Argon-Helium cryoablation therapy,21 lesions (77.78%) were diagnosed as complete ablation with CEUS and 22 (81.48%) with CECT.Contrast enhancement within lesions was demonstrated in 6 lesions (22.22%) with CEUS and 5 (18.52%) with CECT.As compared to CECT,the sensitivity,specificity,positive and negative predictive value,and accuracy of CEUS in diagnosing tumor residue 1 month after treatment was 80.00% (4/5),90.91% (20/22),66.67% (4/6),95.24% (20/21),and 88.89% (24/27) .respectively.Conclusion CEUS is an effective alternative for the evaluation of efficacy of Argon-Helium cryoablation in the treatment of liver malignancies.

The multiplex polymerase chain reaction (PCR) technique was applied to detect the SARS-CoV (severe acute respiratory syndrome-associated coronavirus) specific target cDNA fragments in the present study. The target cDNA fragments of SARS-CoV were synthesized artificially according to the genome sequence of SARS-CoV in GenBank submitted by The Chinese University of Hong Kong, and were used as simulated positive samples. Five primers recommended by World Health Organization (WHO) were used to amplify the fragments by single PCR and multiplex PCR. Three target cDNA fragments (121, 182 and 302 bp), as well as the three different combinations of any two of these fragments, were amplified by single PCR. The combination of these three fragments was amplified by multiplex PCR. The results indicated that the multiplex PCR technique could be applied to detect the SARS-CoV specific target cDNA fragments successfully.
