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 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 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 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 investigate the safety and effectiveness of Solitaire FR stent mechanical thrombectomy combined with 5F Navien catheter aspiration technique for the treatment of acute middle cerebral artery occlusion.Methods From February 2016 to May 2016,the case data of 11 consecutive patients with acute middle cerebral artery occlusion treated with Solitaire FR stent mechanical thrombectomy combined with 5F Navien catheter aspiration technique at the Department of Neurosurgery,Xuanwu Hospital,Capital Medical University were enrolled retrospectively.The age,gender,National Institutes of Health Stroke Scale (NIHSS) score on admission,thrombolysis in cerebral infarction (TICI) grade,operation-related complications,NIHSS score at 24 h after operation,and modified Rankin Scale (mRS) score at day 90 after operation were documented.The relevant data differences before and after treatment were analyzed with the SPSS software.Results Among the 11 patients with acute middle cerebral artery occlusion,7 were men and 4 were women,the age ranged from 44 to 78 years,and the mean age was 66 ± 11 years.The preoperative and postoperative NIHSS scores were 18 ± 3 and 8 ±4 respectively.There was significant difference before and after treatment (t =5.327,P ＜ 0.01).The recanalization of occluded middle cerebral artery achieved successfully.The follow-up at day 90 after operation,the good prognosis of the patients (mRS 0-2) was in 7 cases.No complications associated with severe M1 segment catheter operation occurred.Conclusion The preliminary experience showed,Solitaire FR stent mechanical thrombectomy combined with 5F Navien catheter aspiration technique for the treatment of acute middle cerebral artery occlusion was a safe and effective endovascular mechanical thrombectomy method.

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.
