Objective:To investigate the effects of the miR-149 on the growth and invasion of prostate carcinoma cells. Meth-ods:Real-time fluorescence quantitative polymerase chain reaction was performed to detect the expression of miR-149 on prostate car-cinoma tissues and paraneoplastic tissues. The PC3 and DU145 cells were transfected with miR-149 mimics and negative controls. The cell growth and invasion abilities were tested in terms of colony formation and via Transwell invasion assay. The cells were transfected with the siRNA of the target gene FOXM1 and siRNA control. Western blot was used to detect the expression of FOXM1. The cell colo-ny formation and invasion ability were also detected. Results:Compared with the paraneoplastic tissues, miR-149 was down-regulated in the prostate carcinoma tissues (P<0.01), and the FOXM1 mRNA was highly expressed (P<0.01). PC3 and DU145 cells with miR-149 mimics had only a few colonies and invading cells (P<0.01). Moreover, PC3 (P<0.01) and DU145 (P<0.05) with miR-149 mimics had a low protein level of FOXM1. The FOXM1 expression was knocked down by the siRNA of FOXM1 in the PC3 and the DU145 cells (P<0.01). The knocking down of FOXM1 resulted in an inhibition of the cell colony formation and invasion abilities (P<0.01). Conclusion:The miR-149 inhibits prostate carcinoma cell growth and invasion by suppressing the FOXM1. Our data suggest that miR-149 may function as an effective tool for the molecular treatment of prostate cancer.

In order to examine whether the neuronal losses occur in cerebral and cerebellarcortices,we used two age groups of rats,the adult group aged 12 months containing8 animals and the old group aged 23～24 months,10 animals.After intraventriculardouble infusions with Koenig's acacia gum-formalin,a small piece of brain tissue,lessthan 2 mm in thickness,were removed from the cerebral and cerebellar cortices ofeach animal.All tissues were sectioned in paraffin and stained by H and E.Thecells were counted directly with an occular micrometer,in an area of 200 ?m~2 incerebral cortex and in a straight line of a length span of 5 mm in cerebellar cortexrespectively.The data from two age-groups were treated statistically.A significant neuronal loss were observed in both of cerebral and cerebellarcortices in the old rats.The pyramidal cells of V layer of parietal area fell from themean value of 22.75?1.76/200 ?m~2 in the adult group to 16.68?1.99/200 ?m~2 in theold.The decrease of percentage was 26.7%.The Purkinje cells fell from 98.87?3.72/5mm in the adult to 77.2?8.27/5 mm in the old,and the decrease of percen-tage was 21.9%.The t-test demonstrated that the difference between two age-groups both in cerebral and cerebellar cortices were significant(P

Objective To discuss the biological and pathological features, diagnosis, treatment and prognosis of primary malignant mel-anoma of the foreskin. Methods The diagnosis, treatment, and follow-up of one case of primary malignant melanoma of foreskin treated in our hospital was reported, and the related literatures were reviewed. Results The tumour stage of the patient was stage I, and the patient was given partial amputation of the penis and bilateral inguinal lymph node dissection. Chemotherapy and immunotherapy were conducted at the same time. And there was no recurrence metastasis of during the postoperative follow-up of 54 months. Conclusion Primary malignant melanoma of the foreskin is rare in clinical and it is of high malignant degree. Its diagnosis depends on pathology and surgery is the main treatment. Postoperative chemotherapy and immunotherapy can prolong the survival time of patients, but the overall prognosis is poor.

Preventing and curing emergency infectious diseases,such as A H1N1 influenza,is a public health practice,and its relevant ethical problems are pubic health ethical problems,mainly manifesting as the conflicts between individual interests and public interests,individual freedom and quarantine,individual privacy right and releasing partial medical information,and choosing one's own doctors and compulsory treatment.The core of the issue is that individual interests should be submitted to the public interests,and at the same time government and society should respect individual's freedom,privacy and right of health.

Objective To investigate the relationship between levels of ceruloplasmin (CP) and inflammation grade,fibrosis stages in liver of patients with chronic hepatitis B (CHB),and to establish liver fibrosis non-invasive model and evaluate its diagnostic value for liver pathological stages.Methods Both liver biopsy samples and sera were collected from 148 consecutive CHB patients in Liver Center,First Affiliated Hospital,Fujian Medical University during January 2009 to June 2011.The relationships between CP and liver pathological stages were analyzed using Spearman rank correlation analysis.Receiver operator characteristic (ROC) curve was used to evaluate the diagnostic value of CP for liver pathological stages.The diagnostic values of relevant indicators were analyzed by Logistic regression.The liver pathology-predicting model was built and the diagnostic value of the model was analyzed by ROC curve.Results The mean values of CP in 148 CHB patients with liver inflammation grades of G1 to G4 were (212.5 ± 34.9),(205.5± 32.0),(201.4 ± 37.7) and (172.8 ± 20.4) mg/L,respectively,which were significantly different by ANOVA test (F=6.309,P＜0.01).Similarly,the mean values of CP in patients with liver fibrosis stages of S1 to S4 were (217.4±32.3),(206.0±37.7),(194.2±29.8) and (179.7±30.4) mg/L,respectively,which were significantly different by ANOVA test (F =8.608,P ＜ 0.01).Spearman rank correlation analysis showed that CP was negatively correlated with liver inflammation grades (r=-0.316,P＜0.01) and fibrosis stages (r=-0.404,P＜0.01).ROC curve analysis revealed that the area under the curves (AUC) were 0.71 (S≥2),0.70 (S≥3) and 0.72 (S=4).Multiple Logistic regression analysis showed that CP,α-fetoprotein,cholesterol,platelet and age were independent predictors for liver fibrosis.ROC curve analysis revealed that AUC were 0.84 in model-1 (S≥2),0.83 in model-2 (S≥3) and 0.87 in model-3 (S=4).The accuracy rates were 71.8％,80.3％ and 79.2％,respectively.Conclusions The CP levels are negatively correlated with inflammation grades and fibrosis stages in the liver of CHB patients.CP could be an important non-invasive indicator for liver fibrosis and the model including CP can be used to predict liver fibrosis in CHB.

Objective To investigate the relationship between serum HBeAg level and inflammation grade (G)/fibrosis stage (S) in the liver tissues of chronic hepatitis B (CHB) patients in the immune clearance phase (IC). Methods Both liver biopsy samples and serum samples were consecutively collected from CHB patients in Liver Center,First Affiliated Hospital,Fujian Medical University during March 2007 to June 2010.Electro-chemiluminescence and fluorogenic quantitative polymerase chain reaction (PCR) methods were used to determine HBeAg titer and hepatitis B virus (HBV) DNA level,respectively.The relationships between HBeAg titer and liver pathological stages were analyzed using Spearman rank correlation analysis.Receive operating characteristic (ROC) curve was used to evaluate the diagnostic value of HBeAg for liver pathological stages.Results Totally 249 patients with CHB were enrolled into this study.The serum HBeAg absorbances in patients with liver inflammation G1 to G4 were (2.93±2.85),(2.96±2.74),(2.69±2.67) and (2.30±2.41) lg s/co,respectively,while those in patients with liver fibrosis S1 to S4 were (2.99±2.74),(2.89±2.73),(2.58±2.55) and (2.32±2.44) lg s/co,respectively,which indicated that serum HBeAg titers were significant different in patients with different grading and staging of liver tissues (x2 =47.13,P＜0.01; x2 =74.12,P＜0.01).Spearman rank correlation analysis showed that serum HBeAg titer was negatively correlated with inflammation grades and fibrosis stages of liver tissues (r=-0.418 and-0.532,respectively; both P＜0.01).ROC curve analysis revealed that the areas under the curve (AUC) were 0.74 (G≥≥3) and 0.73 (G≥4),and the HBeAg (s/co) cut-off values were 2.95 and 2.64 lg s/co,respectively.Similarly,ROC curve analysis revealed that the AUC were 0.80 (S≥3) and 0.77 S≥4),and the HBeAg cut-off values were 2.99 and 2.82 lg s/co,respectively.Conclusions The serum HBeAg titer is negatively correlated with the inflammation grades and fibrosis stages m liver tissues of CHB patients in IC phase.The level of HBeAg may be used as an adjunctive noninvasive marker to reflect the inflammation and fibrosis status in the liver.

Objective To analyze quantitatively the histological components, and to observe the morphological changes of the transition zone in benign hyperplastic prostates (BPH) and adult normal prostates. Methods The quantitative morphometry of 40 BPH specimens obtained from suprapubic transvesical prostatectomy and 10 normal prostatic specimens (controls) were performed with computer-assisted image analysis system,and all the samples were stained with hematoxylin and eosin (HE) and the Masson trichrome.The area percentages of stromal (smooth muscle and connective tissue),glandular epithelial and luminal components,the average areas of acini,lumens and epithelia,and the heights of epithelial cells were quantitated,respectively. Results ①The mean area percentages of different components between control group and BPH group were as follows: smooth muscles,(23.83?8.53)% vs (35.35?8.33)% ( P 0.05);epithelia,(26.26? 7.45)% vs (17.76?4.61)% (P0.05).②The average areas of acini, epithelia and lumens of control group and BPH group were ( 0.087?0.028)mm 2 vs (0.062?0.030)mm 2 (P

Objective To investigate the association between hepatitis B virus (HBV)genotype, the mutations in HBV basic core gene promoter(BCP), pre C/C gene region and treatment response to interferon (IFN)α-1b. Methods Hepatitis B e antigen (HBeAg)-positive chronic hepatitis B (CHB) patients were treated with IFNα-Ib for 6 months and were followed up for 6 months after the end of treatment. Restriction Fragment Length Polymorphism (RFLP) was used for determining HBV genotype. HBV DNA was amplified by polymerase chain reaction (PCR) and analyzed for BCP and pre C/C gene region by sequencing. Measurement data were compared using t test and analysis of variance. Enumeration data were compared using chi-square test, Fisher exact probability test.Logistic regression analysis was utilized for multi-factor analysis. Results There were 39 patients who completed the treatment and follow up in this study. At the end of treatment, 16(41.0%) patients showed response to the IFNα-lb treatment. At the end of follow-up, four out of 16 patients who achieved on treatment response relapsed. Among 3a patients, 29 (74.4 %) were infected with genotype B and 10 (25. 6%) with genotype C. The treatment response rates were not significant different between the groups with different genotypes. The double mutation pattern (T1762/A1764) was found in eight (20. 5%) patients. The response rates to IFNα-lb treatment were not significant different between the group with and without double mutation pattern. A1896 mutation was detected in eight patients at baseline. Three of them became HBeAg negative at the end of treatment and returned to HBeAg positive during follow-up. The non-lyphocyte epitope mutations, L60V and I97L, were found in 15 patients (38. 5%) and 14 patients (35.9%), respectively. At the end of follow-up, the patients with 60V had a significantly lower HBeAg seroconversion rate and HBV DNA undetectable rate compared to the patients with 60L (Fisher exact probability test; P = 0.0126 and 0.0069,respectively). The HBV DNA undetectable rates in the patients with 97I were significantly lower than those in patients with 97L both at the end of treatment and the end of follow-up (Fisher exact probability test; P= 0.0484 and 0. 0024, respectively). Logistic regression analysis results showed that there was no association between the above viral mutations and the treatment response to IFNαlb. Conclusions There is no association between HBV genotype, BCP double mutation pattern and IFN-α treatment response. The non-lyphocyte epitope mutations, L60V and I97L, may have impact on IFN-α treatment response.

Objective: To observe and study the influence of external drainage of lateral ventricle for continuous ventricular infusion and lumbar cistern drainage for the serum and cerebrospinal fluid on inflammatory mediators of patients with intracranial infection, in order to understand the clinical application value of the treatment methods. Methods: From June 2016 to May 2018, 56 patients with intracranial infection in the People's Hospital of Lianshui County were selected in the study and randomly divided into two groups according to the random allocation principle, with 28 cases in each group.The control group was treated with repeated lumbar intrathecal drug therapy, the observation group was treated with external drainage of lateral ventricle for continuous ventricular infusion and lumbar cistern drainage.The serum and cerebrospinal fluid inflammatory mediators of two groups before treatment and at the first and second week after treatment were compared. Results: The serum and cerebrospinal fluid inflammatory mediators of the two groups before treatment had no statistically significant differences(all P>0.05). The serum levels of IL-1β, IL-6 and IL-8 of the observation group at the first and second week after treatment were (2.27±0.28)μg/L, (9.25±0.89)μg/L, (11.15±1.35)μg/L and (1.65±0.20)μg/L, (7.04±0.81)μg/L, (8.42±0.79)μg/L, respectively, which were significantly lower than those of the control group [(4.63±0.38)μg/L, (11.92±1.35)μg/L, (14.28±1.75)μg/L and (3.20±0.29)μg/L, (9.41±1.02)μg/L, (11.32±1.47)μg/L] (t=26.456, 8.737, 7.493, 23.282, 9.628, 9.195, all P<0.01). Two weeks after treatment, the levels of IL-1, IL-6 and IL-8 in CSF of the observation group were (1.51±0.15)μg/L, (5.14±0.45)μg/L and (5.96±0.59)μg/L, respectively, which were significantly lower than those of the control group(t=12.876, 12.810, 14.272, all P<0.01). The levels of leukotriene B4(LTB4), substance P(SP) and nitric oxide(NO) in serum and cerebrospinal fluid of the two groups continued to decrease after treatment for one week and two weeks, and those in the observation group were lower than the control group(all P<0.05). Conclusion External drainage of lateral ventricle for continuous ventricular infusion and lumbar cistern drainage can significantly decrease the serum and cerebrospinal fluid inflammatory mediators of patients with intracranial infection, so the treatment method has high clinical application significance.

OBJECTIVETo explore the safety and efficacy of Shaobei injection in the management of I(-II( degree rectal prolapse.

METHODSA total of 80 patients eligible for the inclusion criteria were divided into 2 groups: 40 patients in the treatment group (treated with Shaobei injection) and 40 cases in the control group (treated with Xiaozhiling) respectively. The short-term efficacy was identified by the length of rectal prolapse and the depth of rectocele demonstrated by the defecography while the long-term efficacy was evaluated by the length of rectal prolapse. In addition, the safety was assessed by the occurrence of postoperative complications.

RESULTSThe variation of the lengths of rectal prolapse and the depth of rectocele demonstrated by the defecography at the sixth month follow up in the two groups did not reach significant difference (P>0.05). After 2 year follow up, 37 patients (92.5%) in the treatment group and 35 cases(87.5%) in the control group was cured. Therefore, there was no significant difference in the long term efficacy between the two groups (P>0.05). The adverse events in the therapy group(10%) was less than that in the control group (45%)(P<0.01).

CONCLUSIONSShaobei injection in the management of I(-II( degree rectal prolapse has a similar efficacy of short-term and long-term higher safety compared to Xiaozhiling injection.
