Objective To study the expression and its clinical significance of Oct4 in prostate cancer.Methods The Oct4 mRNA expression levels in 2 normal prostate (NP) samples and 8 prostate cancer (Pca) samples were determined by reverse transcription polymerase chain reaction (RT-PCR) analysis.The Oct4 protein expression levels in 10 NP samples,10 benign prostate hyperplasia (BPH) samples and 45 Pca samples were detected by immunohisochemical analysis.Results The relative expression levels of Oct4 mRNA were 0.91,0.76,0.66,0.63,0.55,0.50,0.48,0.42 in 8 Pca samples and 0 in 2 NP samples,respectively.The positive rates of Oct4 protein expression was higher in Pca tissues than in NP and BPH tissues (91.1% vs.0.0%,91.1% vs.0.0%,both P<0.05).The level of Oct4 protein was increased with higher hostologic grade and clinical stage of prostate cancer.The strong positive rates of Oct4 expression were 72.7% and 30.0% in Pca tissues with and without lymph node metastasis respectively,and there was a significant difference in the strong positive rate between them (P<0.05).Conclusions The Oct4 expression is closely related to the differentiation and invasion of tumor.Oct4 might be an important index for the prognosis of prostate cancer.

Objective To show the international protocols for blood pressure monitoring based on a real example. Methods The assessment process of international protocol that can be released by Working Group on Blood Pressure Monitoring of European Society of Hypertension was evaluated. Results 33 participants were selected, which all indexes in evaluation stage one and stage two of the indicators were detected through. The 95% consistency interval in difference between tested device and reference monitor was 10.65~-12.67 mmHg for systolic BP and 13.68~-14.03 mmHg for diastolic BP, and there were 7.1% (7/99) and 6.1% (6/99) of valid points out of the 95% consistency interval. Conclusion The measured automatic blood pressure in the normal environment, measuring accuracy and the standard with the control of mercury -type sphygmomanometer is coincident, so it can be recommended for home application.

Objective To compare blood pressures results measured by automated sphygmomanometer and standard mercury sphygmomanometer,and to investigate the application of measurements consistency evaluation method in accurate measurement of automated sphygmomanometer.Methods Intraclass correlation coefficient was used to estimate the reliability of repeated measurements,and Bland -Altman method was adopted to evaluate the consistency between automated sphygmomanometer and standard mercury sphygmomanometer.Meanwhile,the results were compared with protocol of European Society of Hypertension.Results The tested automated sphygmomanometer did not adapt to the criteria of European Society of Hypertension.The intraclass correlation coefficient of mercury sphygmomanometer was 0.937 for systolic blood pressure,0.849 for diastolic blood pressure.The intraclass correlation coefficient of tested sphygmomanometer was 0.944 for systolic blood pressure,0.929 for diastolic blood pressure.The 95% consistency interval was(-10.20 to 16.94)mmHg for systolic blood pressure and(-6.25 to 11.69)mmHg for diastolic blood pressure.Conclusion Normally,Bland-Altman method has the same judgment result with protocol of European Society of Hypertension.

Background Our pervious antibacterial studies on several traditional Chinese medicines have found that Patchouli oil from Pogostemon cablin had significant antibacterial activity against methicillin-resistant Staphylococcus aureus (MRSA),which has spread worldwide and infected innumerable people.In order to find the more active natural substances in Patchouli oil,one of the major components,Pogostone,was isolated and its antibacterial activity was evaluated in vitro and in vivo in this study.Methods In vitro test,Pogostone was screened for antimicrobial properties against 83 bacteria comprising 35 gram positive and 48 gram negative bacteria strains via the agar double dilution method.In vivo test,specific pathogen free (SPF) strain of both male and female white Kunming mice,weighing 18-22 g,were used to test the protective ability of Pogostone after being injected with the median lethal doses (MLDs) of the tested strains.Results In vitro test,Pogostone could inhibit both gram negative bacteria (0.098-1 600 μg/ml) and gram positive bacteria(0.098-800 μg/ml).For Corynebacterium xerosis and some Chryseobacterium indologenes,the minimum inhibitory concentration (MIC) values of Pogostone were extremely low (<0.098 μg/ml).It was significant that Pogostone was also active against some drug-resistant bacteria like MRSA.Furthermore,Pogostone showed antibacterial activity in vivo against Escherichia coli (E.coli) and MRSA via intraperitoneal injection.Ninety percent of the mice infected with E.coil could be protected at the concentrations of 50 and 100 mg/kg,and 60% of the mice at 25 mg/kg,while the rate of protection for the mice infected with MRSA was 60% and 50% at doses of 100 and 50 mg/kg,respectively.Conclusion Pogostone could be developed as a potential antibacterial agent for clinical therapy.

Abstract
In order to achieve the goal of reducing the smoking rate among Chinese adults at ages of 15 years and above to below 20% by 2030, smoking cessation services require to be reinforced. The current Chinese smoking cessation service system includes short-term smoking cessation interventions and smoking cessation hotlines at the population level, and smoking cessation clinics at the individual level; however, these smoking cessation services suffer from problems of low awareness, low accessibility and low utilization rate. Based on the publications pertaining to smoking cessation services and released policy documents in China until June 2022, this review analyzes the current status, problems and causes of smoking cessation services, and proposes suggestions for improving the smoking cessation service system construction in China.

Objective To study the diagnosis and treatment of cytomegalovirus (CMV) infection after liver transplantation. Methods The clinical data of 111 patients who received liver transplantation from November 2000 to December 2007 in our hospital were analyzed retrospectively. The recipients were diagnosed as having CMV infection by the predisposing factors, clinical symptoms and detection of CMV-PP65 and CMV-IgM in peripheral blood specimens in combination with chest X-ray. The treatment of CMV infection was administration of Ganciclovir. Results Five recipients were diagnosed as having CMV infection, with the incidence of 4.5%. Two were diagnosed as having CMV pneumonitis, with the incidence of 1.8% (40% of the recipients having CMV infection). Two were both improved. Three were diagnosed as having CMV active infection. Two of them were cured and one was improved. Conclusion The detection of CMV-PP65 is necessary for early diagnosis and guiding treatment of CMV infection. Ganciclovir can exert significant therapeutic effects on CMV infection.
