Objective To investigate the condition of self-management of patient controlled analgesia pump in patients in the ICU.Methods 82 patients in ICU were selected in July 2014 and were randomly divided into the observation group and the control group with 41 cases in each.In the observation group,the PCAP was fixed on the bedrails of patients' bed and controlled by themselves to acquire satisfactory analgesia effect.In the control group,the PCAP was operated by the nurses.Pains scores was compared between the two groups.Results The different position of PCAP showed the different scores of pain in the patients.The pain scores in the observation group (2.93±1.47) was significantly lower than that in the control group (3.76±1.36),P＜0.05.Conclusions Proper position of PCAP and controlled by patients can effectively reduce postoperative pain of patients in the ICU,and then reduce their suffering and improve their comfort.

Hepatitis A is one of the global public health problems,and China has high prevalence. In order to decrease the incidence of hepatitis A,China has integrated Hepatitis A vaccine into Expanded Program on Immunization (EPI) in 2007. The paper will provide some ideas on the immunogenicity and impact factors of the different types of hepatitis A vaccines that are used in China.

Objective To find a new method to prepare the acellular matrix of the penile cavernous body. Methods Intact specimens of the penile cavernous body were collected from healty adult rabbits,treated with Triton-X100 and NH3?H2O,and then stained with HE.Light microscopy was employed to observe the acellular cells.Results Acellular matrix of the penile cavernous body was obtained after a 25-day treatment with Triton-X100 and NH3?H2O.The matrix was intact.HE staining showed that the matrix was composed of regularly arranged elastic fibers with wide intra-spaces without any cells inside.Conclusion Acellular matrix of the penile cavernous body can be prepared by using Triton-X100 and NH3?H2O.

AIM: To explore the feasibility of culturing human umbilical vein endothelial cells ( HUVEC ) on acellular corneal stroma and performing the posterior lamellar endothelial keratoplasty ( PLEK ) treating corneal endothelial decompensation.
METHODS: Thirty New-Zealand rabbits were divided into three groups randomly, 10 rabbits for experimental group, 10 for stroma group and 10 for control group. Corneal endothelial cells were removed to establish animal model of corneal endothelial failure. PLEK was performed on the rabbits of experimental group and stroma group, and nothing was transplantated onto the rabbits of control group with the deep layer excised only. Postoperative observation was taken for 3mo. The degree of corneal edema and central corneal thickness were recorded for statistical analysis.
RESULTS:Corneas in experimental group were relieved in edema obviously compared with that in stroma group and the control group, and showed increased transparency 7d after the operation. The average density of endothelial cells was 2 026. 4±129. 3cells/mm2 , and average central corneal thickness was 505. 2±25. 4μm in experimental group, while 1 535. 6±114. 5μm in stroma group and 1 493. 5±70. 2μm in control group 3mo after operation.
CONCLUSION:We achieved preliminary success in our study that culturing HUVEC on acellular corneal stroma and performing PLEK for corneal endothelial decompensation. HUVEC transplanted could survive in vivo, and have normal biological function of keeping cornea transparent. This study provides a new idea and a new way clinically for the treatment of corneal endothelial diseases.

ObjectiveTo summarize the recent therapeutic effects of mesh-plug tension-free hernioplasty in elderly inguinal hernia. MethodsAll cases were performed with mesh-plug case-hardened products, which are manufactured by American Bard Company. ResultsAll the operative procedures were performed smoothly. Postoperative complications were:6 cases of urinary retention,4 scrotal hydroceles,2 persistent wound pain,2 local lightly projections with foreign body sensation,2 hypoincisional haematoma. 1～24 months of follow-up were taken,2 recent recurrences were reported. ConclusionMesh-plug tension-free hernioplasty is a perfect surgical operation. Its main characteristics are:simple performance, less trauma, tension-free, time-saving, good recent therapeutic effect, and fewer recent recurrence. It is especially suitable to the elderly patients and/or Patients with other diseases.

Cyclin D is the most closely relationship with tumor ,and it is currently known one of the sub-types of cyclins.CyclinD1,as a positive regulatory factor ,has an important role in the process of cell cycle ,espe-cially in cell proliferation and division .CyclinD1 is unusually up-regulated in lots of human cancers .CyclinD1 is a recently discovered protein which is highly expressed in the urinary tumors ,and its expression in tumors is asso-ciated with a more aggressive phenotype ,prognosis and recurrence .Therefore,the research of the target point to CyclinD1 in the urinary tumors may provide a new method for the therapy to urinary tumors .

Objective The incidence of laryngeal cancer has characteristic of regional differences, but the etiology is not clear. The aim of this study was to analyze the correlation between RECK gene promoter methylation and prognosis of laryngeal squamous cell carci-noma patients through detecting the RECK gene methylation status of primary laryngeal squamous cell carcinoma and adjacent tissues . Methods Methylation specific PCR assay was used to detect the RECK gene promoter methylation status of 70 laryngeal squamous cell carci-noma specimens in our hospital from July 2006 to Dcember 2007, and the differences of methylation status with different pathological parame-ters were compared.The correlation between RECK gene promoter methylation and prognosis of 64 patients completed five-year follow-up was analyzed. Results The RECK gene methylation rate (86.67%) of patients with poor differentiation in tumor cells was much higher than that of the patients with a moderate and better tumor cell differentiation (43.64%) (P<0.05).In 29 pairs of laryngeal cancer-adjacent tis-sues specimens matches, the RECK gene methylation in laryngeal carcinoma (55.12%) was higher than normal tissues (27.59%) ( P=0.029).RECK gene methylation significantly shortened the tumor free survival and overall survival analyzed by Log-rank (P=0.024, P=0.017).Lymph node metastasis and clinical stage in classⅢ-Ⅳsignificantly shortened the tumor free survival and overall survival (P=0.029, P=0.024;P=0.033, P=0.032).Moderate and better tumor cell differentiation significantly shortened the tumor free survival (P=0.024, P=0.049).Lymph node metastasis, clinical stage, and RECK gene methylation were independent risk factors of overall survival. Conclusion RECK gene promoter methylation in human laryngeal squamous cell carcinoma is an early event and may occur in the adjacent normal tissues, predicting a poor prognosis in patients.

Objective:This study has two objectives. One is to detect the methylation status of reversion-inducing cysteine-rich protein with Kazal motifs (RECK, a new tumor suppressor gene) gene promoter in primary laryngeal squamous cell carcinoma and nor-mal laryngeal mucosa. The other is to analyze the correlation between RECK gene methylation status and radiosensitivity in laryngeal squamous cell carcinoma. Methods:Methylation-specific polymerase chain reaction was used to detect the RECK gene methylation of 70 specimens of laryngeal squamous cell carcinoma and 15 normal tissues of laryngeal mucosa. The patients underwent six cycles of ra-diotherapy and were followed-up for 5 years. The correlation between RECK gene methylation status and radiosensitivity in laryngeal squamous cell carcinoma was analyzed. Results: After six cycles of radiotherapy, 47 patients (67.14%) showed sensitivity and 23 (32.86%) showed tolerance to radiotherapy. The methylation level of the RECK gene was lower in the radiation-sensitive group than in the nonradiation-sensitive group (P<0.05). The methylation level of the RECK gene was lower in the remission group than in the non-remission group. RECK gene methylation could increase the risk of cancer by approximately 5.010 times (OR=5.010, 95%CI:1.616-15.533). Conclusion:RECK gene promoter methylation in human laryngeal squamous cell carcinoma is an early event that is correlated with the patient's sensitivity to radiotherapy. Thus, the patient's sensitivity to radiation can be predicted by detecting the meth-ylation status of the RECK gene promoter.
