Objective To examine the cellular distribution and the role of a-catenin in epidermal tumors. Methods Expression of a-catenin was investigate d by immunohistochemical staining in 20 patients with Bowen′s disease (BD), 20 squamous cell carcinoma (SCC), 20 basal cell carcinoma (BCC), and 40 normal cont rols. Results Expression of a-catenin was strongest on the cell membranes of b asal cells, but nearly negative in the cytoplasm and the nuclei of epidermal cel ls in normal controls. Expression of a-catenin was significantly lower on the cell membranes in SCC and BCC cells than that in normal epidermal cells (P

Objective To explore the significance of sample cultivation and drug resistance of the patients in PICU with severe lower respiratory tract specimens.Methods 1 107 pathogenic bacteria of lower respiratory tract samples collected were analyzed and the drug resistance was kept watch on.Results A total of 1107 samples were cultured into 948 strains of pathogens,with the positive rate of 85.64%,and 616 strains of Gram negative bacteria accounting for 64.98%,of which 145 strains of Pseudomonas aeruginosa(15.30%),Klebsiella pneumoniae 135(14.24%),Acinetobacter spp 131(13.82%),large intestine Egypt Greek bacteria 89(9.4%);Gram positive cocci 129(13.61%),the main pathogen was staphylococcus aureus and Fungi 203(21.41%),the main pathogen was candida albicans.Carbapenems was the most active antibiotics for gram negative bacill,and vancomycin for gram positive cocci.Conclusion Infectious bacteria have high selectivity to the sensitive antibiotics,and doctors should carefully use antibiotic according to the susceptibility test results in order to reduce hospital infection and the emergence and spread of resistant strains.

Methods A retrospective review was conducted in 50 cases with epilepsy,and temporal lobe was resected by microsurgery from June 1996 to Oct. 2003. Results Follow-up patients from six months to five years.The follow up showed healing outcome in 25 cases,good results in 13 cases,unsatisfactory outcome in 9 cases,no improvement in 3 cases.Slight paresis 6 cases,divagation 8 cases,psychosis 5 cases and no death case. Conclusions Application of microsurgery can obvously improve the clinical result of patients with temporal lobe epilepsy and decrease the complication after operation.

Objective To discuss the optimal nursing strategy for the patients receiving basilar artery angioplasty. Methods During the period from October 2011 to October 2013 at authors’ hospital, a total of 34 patients received basilar artery angioplasty. According to the hospital nursing core regulations , hanging of nursing warning tags, monitoring of blood pressure of both upper limbs, measurement of average blood pressure of both upper limbs after admission, and 72 hours ECG monitoring of blood pressure after operation as well as maintaining the patient’s blood pressure at a stable level around 110 - 120/70 - 80 mmHg, etc. were strictly carried out. Results Before operation no falling on the ground occurred in all the patients. After the operation, no severe complications such as hemorrhage occurred. All patients were in satisfactory condition at the time of discharge. Conclusion Strictly carrying out nursing core regulations, rigorously performing the nursing measures and monitoring the blood pressure before, after and during basilar artery angioplasty are helpful in reducing the incidence of perioperative complications.

Objective To investigate the effects of glucocorticoids o n the expression of Th1/Th2 cytokines at mRNA and protein levels in peripheral b lood mononuclear cells (PBMCs) of patients with systemic lupus erythematosus (SL E). Methods Th1 cytokine (IFN-IL-10) in PBMCs fro m 48 patients with SLE were detected before and after treatment with glucocortic oids by RT-PCR for mRNA expression and ELISA for protein production. The systemi c lupus erythematosus activity measure (SLAM) scores of patients were compared b efore and after treatment. Results After treatment, the expression and product ion of IFN- versus 1.4094 pg/mL; P

Objective To study the telomerase activity,the keratinocyte apoptosis in condyloma ac-cuminatum(CA)and the correlation between them.Methods CA specimens from30patients were stud-ied,and compared with normal tissue and tumor cell lines.Telomerase activity was detected with telomeric repeat amplification polymerase chain reaction(TRAP)-ELISA.Terminal deoxynucleotidyl transferase(TdT)-mediated biotin dUTP nick end-labeling(TUNEL)was used to evaluate apoptotic cells.Results Increased telomerase activity was detected in27(90%)patients with CA,with A 450 ranging between0.50and2.76(mean1.3022).Apoptotic keratinocytes were found in24out of30CA cases(80%).A statistically signifi-cant inverse correlation was found between telomerase activity and apoptotic index(r =-0.52,P=0.004).Conclusion Keratinocyte telomerase is activated in condyloma acuminata,which is correlated with the downregulation of apoptosis,thus they might be involved in the pathogenesis of CA.

Objective To study the effects of Interferon(IFN)in chronic hepatitis B patients genotype B and C.Methods 20 cases were genotype B ,23 cases were genotype C,all the patients were treated with 5 million units of IFN-a-lb,im,qod,for 12 months,viral markers,liver function and adverse drug reactions were observed.Results There was no statistically significant difference between B,C genotype in the negative conversion rate of HBV-DNA (60.0% ,39.1%),the negative conversion rate of HBeAg(42.9% ,30.8%),anti-HBe seroconversion rate(35.7% ,23.1 %)and the rate ALT normalization(85.0% ,73.9%)(t = 1.86,0.69,0.68 ,0.79,P ＞ 0.05).Conclusion The results suggested that therapeutic efficacy of IFN-α-lb was not significantly different between B,C genotypes.

Objective To observe the effects of endoplasmic reticulum stress (ERS) on the activation of monocytes induced by high glucose and explore the underlying mechanism.Methods The monocyte cell line THP-1 was stimulated with high glucose,and then treated with molecular chaperone betaine.The levels of glucose regulation protein 78 (GRP78) and p-JNK,which were associated with ERS were detected by real-time PCR and Western blotting.The proliferation of the cell line was detected by MTT method.Transwell and immunofluorescence were applied to observe the chemotaxis and phenotype of cells respectively.Results The levels of GRP78 and p-JNK of THP-1 cells stimulated by high glucose were significantly increased compared with the normal control group (all P ＜ 0.05).The proliferation and chemotactic were also enhanced (all P ＜ 0.05).The number of cells in M1 phenotype was increased remarkably (P ＜ 0.05).All the indexes above could be rescued by betaine.Conclusion The activation of THP-1 cells can be induced by high glucose through ERS,while molecular chaperone betaine can reverse the activation.

Background and purpose: Anti-tumor chemotherapy compromises normal immune function of the patients. There were many reports that chemotherapy for advanced colorectal cancer often inhibit the cellular immune function. The effect of FOLFOX regimen chemotherapy on immunity of the patients with colorectal cancer before and after therapy was studied, and healthy people were used as a control. Methods: Eighty colorectal cancer patients were treated by FOLFOX regimen, which consisted of 2-hour infusion of oxaliplatin(85 mg/m~2) and 2-hour infusion of leucovorin (CF)(200 mg/m~2) on Day 1, followed by 5-fluorouracil(5-FU) bolus (400 mg/m~2) on Day 1 and 46-hour infusion (2 400 mg/m~2). FOLFOX regimen was repeated at 2-week intervals. Two treatments of the above regimen were defined as one cycle. Flow cytometry was used to detect T lymphocyte subsets and NK cells in blood samples from patients with colorectal cancer before and after therapy. Data obtained fi'om healthy people was used as control. Results: CD3~+, CD4~+ T cells, NK cells and CD4~+/CD8~+ ratio in blood samples were not significant before and after chemotherapy in first day, second week and fourth week(P0.05). Lower CD3~+, CD4~+ T cells, NK cells and CD4~+/CD8~+ ratio were detected in blood samples from cancer group than that from the healthy control(P<0.05). CD8~+ T lymphocyte were reverse. This change was related to the TNM pathological stage. Conclusion: FOLFOX regimen was effective for patients with coloreetal cancer, which can improve patients' life quality and did not impact on the immune function of the patients. The immune function of lymphocytes in peripheral blood of the patients with colorectal cancer was low, and even worse in the patients with late TNM stage. It is valuable for estimating the function of cell immune of the patients, patients prognosis and the role of immune therapy in the treatment of the patients by detecting T lymphocyte subset and NK cell.
