Objective To analyze the advantages of intracrani al hematoma smash puncture (IHSP) in the treatment of cranial hemorrhage for the elderly. Methods A total of 104 cases of cerebral hemorrhage a dmitted in the recent 3 years were collected and divided into 4 grou ps, i.e . group A, elderly with IHSP treatment (n=36), group B, elderly with regular medical treatment (n=33), group C, non-elderly with IHSP treatment (n= 21) and group D, non-elderly with routine therapy (n=14). The clinical and follow-up outcomes were studied and analyzed. Results There w as significant difference in rehemorrhage rate after puncture between grou p A (0/36) and group C (2/21). Significant difference was found in early mortali ty rate in group A (16.67%) and group B (39.40%). The rate of activity of daily living (ADL) 1-2 was significantly higher in group A (58.62%) than group B (5.88 %)(P<0.005) and that of ADL 4-5 was obvious lower in group A (13.79%) than g roup B (47.06%)(P<0.025). Conclusion Intracranial hematoma smash hemorrage is safe and efficient in the treatment of elderly cerebr al hemorrhage, especially in reducing the disability rate.

Objective To observe the efficacy and safety of fluticasone propionate ointment in the treatment of psoriasis vulgaris. Methods A randomized comparative clinical observation was performed in 68 patients with pso-riasis vulgaris, they were divided into experimental group and control group. The experimental group of 34 cases was treated with fluticasone propionate ointment and the control group of 34 cases with kenacort-A ointment. The response was evaluated at 6 weeks. Results The total effective rate of the experimental group was 94.1% and 70.6% in the control group after 6 weeks. There was a significant difference between the two groups in treatment effective rate(P<0.01). Conclusion It is effective and safety for fluticasone propionate ointment in the treatment of psoriasis vulgar-is.

Influenza virus hemagglutinin (HA) is a key factor in the virus's invasion of host cells, involving the binding of the virus to target cells and the fusion of membranes. The proteolytic cleavage and activation of HA by host proteases are prerequisites for the virus to recognize host cells and initiate membrane fusion, and are also essential for viral infection of the host. This article summarizes the proteolytic activation of different subtypes of influenza virus HA by type II transmembrane serine proteases, human tissue kallikreins, and other host proteases, and discusses their potential as targets for antiviral therapy.

Purpose To study clinicopathologic feature of prostate cancer by complete embedding of radical prostatectomy specimen. Methods 108 cases of radical prostatectomy by systematic whole organ embedding were reviewed. Results The patient age ranged from 55 to 80 years ( mean 68. 1 years) . The preoperative average PSA value was 18. 3μg/ml. 59 cases ( accounting for 54. 6% of all prostatectomy cases) were in pT2 stage, while 23. 7% (14/59) in pT2a stage, 8. 5% (5/59) in pT2b, and 67. 8% (40/59) in pT2c. 49 cases (45. 4%)in pT3 stage, while 59. 2% (29/49) in pT3a, 40. 8% (20/49) in pT3b. 3. 6%(3/84)cases presented pelvic lymph node metastasis. 8. 3% (9/108) cases were graded as Gleason Score 6 or less, 61. 1% Gleason Score 7, 30. 6%(33/108)Gleason Score 8 or more. Gleason Pattern 5 component was found in 26. 9% (29/108) cases. Positive margin was observed in 25. 9% (28/108) cases, with 75% (21/28) in pT3 stage and 53. 6% (15/28) having Gleason Pattern 5. Patient in pT2 stage pres-ented mean PSA value of 14. 00 μg/ml, involved in no more than 2 biopsy cores in 68. 5% cases, and more than 5 cores in 4. 3%, while in pT3 stage, presented mean PSA value of 23. 82μg/ml, involved in no more than 2 cores in 19. 6%, and more than 5 cores in 28. 3%. The difference of involved core number was significant in pT2 and pT3 tumors ( P<0. 01 ) . 81. 3% cases graded Gleason Score 6 in biopsy was assigned to Gleason Score 7 or more in prostatectomy. Conclusions Completely sampling radical prostatectomy specimen should be recommended for accurate staging and margin status. Preoperative PSA value, Gleason Score of biopsy, involved core number by cancer is a still helpful parameter for clinical staging and risk estimate.

Objective To investigate the expression of Ezrin in gastric cancer tissues and its clinical significance.Methods Gastric cancer tissues and adjacent normal gastric tissues from 60 patients with gastric cancer were collected from June 2008 to May 2009 at the Southwest Hospital.The mRNA and protein expressions of Ezrin were detected by using the reverse transcription polymerase chain reaction and western blot.The relationship between Ezrin and the gender and age of patients,and tumor differentiation,pathological staging,depth of invasion and lymph node metastasis was analyzed.All data were analyzed using the t test,chi-square test and Spearman rank correlation.Results The Ezrin mRNA expression level was increased in 33 (55%) cases of adjacent normal gastric tissues and 21 (35%) cases of gastric cancer tissues; the Ezrin protein expression level was increased in 45 (75%) cases of adjacent normal gastric tissues and 22 (37%) cases of gastric cancer tissues.The mRNA and protein expressions of Ezrin in the normal adjacent gastric tissues were 1.30 ± 0.04 and 3.57 ± 0.45,respectively,which were significantly higher than 0.53 ± 0.36 and 0.96 ± 0.18 in the gastric cancer tissues ( t =5.309,22.617,P < 0.05 ).The mRNA expression of Ezrin was positively correlated with the protein expression of Ezrin (r =0.602,P < 0.05 ).The mRNA and protein expressions of Ezrin were related to the pathological stages,depth of invasion and state of lymph node metastasis (x2 =6.41,6.49,4.62; 5.40,8.87,4.12,P < 0.05),but not to the gender,age and tumor differentiation (x2 =0.50,0.07,1.07 ; 0.01,1.16,1.96,P > 0.05).Conclusion The mRNA and protein expressions of Ezrin are significantly decreased in the gastric cancer tissue,which might be responsible for genesis,development and metastasis of gastric cancer.

Objective To investigate the p53 gene mutations in Chinese patients with epithelial skin cancers. Methods Biopsies of 22 squamous cell carcinoma(SCC)and 18 basal cell carcinoma(BCC)were analyzed by polymerase chain reaction denaturing gradient gel electrophoresis(PCR-DGGE) and DNA sequencing for alterations in the exons 5~8 of p53 tumor suppressor gene. Results p53 gene mutations were found in 32.5%(13/40)of tumor tissues and 92.3%(12/13) of the mutations occurred at sun exposed areas. 36.4%(8/22)of SCC tissues and 27.8%(5/18) of BCC tissues presented p53 gene mutations. Of the 13 mutations within the exons examined, 76.9%(10/13) were missense mutations and 23.1%(3/13) were nonsense mutations. Twelve of the 13 mutations were of single nucleotide substitutions. Six of the 13 mutations involved dipyrimidine sites, where a C was replaced by a T or CC was replaced by TT(five C→T transitions and one CC→TT transition). Conclusion Ultraviolet(UV) radiation might be related to the pathogenesis of skin cancer. Mutations of p53 gene caused by solar UV might play a significant role in UV tumorigenesis, although other carcinogens might also be involved.
