Objective To analyze the related factors of medical order compliance in patients with chronic prostatitis. Methods 482 patients with chronic prostatitis were investigated by using the National Institutes of Health chronic prostatitis symptom index(NIH-CPSI)、Eysenck personality qusetionnaire( EPQ)and the self-de-signed medical order compliance questionnaire and the patients' disease characteristics and personality were also analyzed.The related factores of medical order compliance in patients were analyzed through hierarchical multiple regression analysis. Results Patients with chronic pwstatitis were younger and their disease condition was seri-ous. Their personality was introverted. They had many psychological problems, such as anxiety, depression, sus-pect, et al. All these were related with patients' compliance. Conclusions Attention should be paid to the patients' personality, and psychotherapy should be given to patients with introverted personality to improve pa-tients' compliance,so that the treatment effect will be increased for patients with chronic prostatitis.

Objective To study the result of Alexandrite laser hair removal after subcutaneous in-jection of?-MSH in anagen-induced C57BL6mice.Methods Hair shafts were depilated by wax/resin mix-ture to induce hair follicles from telogen to anagen in60C57BL6mice.The mice were randomly divided in-to groups A,B,C and D.Groups A and B were injected with0.5mg/kg and0.25mg/kg of?-MSH,respec-tively,on the back skin subcutaneously once a day.Group C was injected with the same dose of normal saline.Group D was treated as blank control.Groups A,B and C were exposed to Alexandrite laser on ana-gen(substageⅣ).Biopsies were taken before treatment and0.5h,2and28days after treatment.Speci-mens were stained with Masson-Fontana method before treatment,and with haematoxylin and eosin after treatment.The cutaneous response was observed after laser hair removal.Hair regrowth was assessed28days after treatment.Results The mean gradation value of folliclar melanin was increased in the test groups than that in control group before laser hair removal.Extent of folliclar damage and cutaneous adverse reaction af-ter laser treatment was more severe in test groups than those in control group.Hair regrowth was less obvious in test groups than that in control group,while local hyperpigmentation was increased in test groups than that in control group28days after treatment.No scarring was observed in3groups.Conclusion Subentaneous injection of?-MSH could increase melanin of the hair,decrease hair regrowth,and enhance local pigmenta-tion after laser hair removal in anagen-induced C57BL6mice.

Objective:To investigate the effect of long-term alcohol intake on sensory information synaptic transmission of mossy fiber-granular cells in the cerebellar cortex of mice.Methods:Twenty healthy male ICR mice aged 6 to 8 weeks were divided into normal saline group(control group) and alcohol intake group(alcohol group) according to random number table, with 10 mice in each group. The mice in alcohol group were injected intraperitoneally with 20% alcohol and the mice in control group were injected with the same amount of saline for 28 days.After the injection, the scalp, muscle tissue and skull were removed in turn, and the dura mater was removed to fully expose the crus II area of cerebellum. The mice were stimulated by air blowing at 30 mm of the ipsilateral tentacle pad with a gas jet device.When the the maximal response site was determined, the NMDA receptor antagonist (D-APV), metabolic glutamate receptor 1 antagonist (JNJ16259685) and N-methyl-D-aspartic acid (NMDA) were perfused on the brain surface of mice. Each drug was perfused for 20 minutes and ACSF was used between the two drugs until the waveform was recovered. Patch clamp amplifier was used to record the changes of potential waveform in mouse cerebellar granule layer. The data were analyzed by the softwares of Clampfit 10.3 and SPSS 22.0.Results:After exposure to wind stimulation, the latency of field potential response in granular layer of mice in alcohol group (11.8±0.7)ms was significantly longer than that in the control group (10.1±0.2)ms ( t=-8.041, P<0.05), and the amplitude of N1 (1.2±0.1) MV was significantly lower than that in the control group (0.6±0.1) MV ( t=-12.728, P<0.05). Compared with the control group, the rise time of P1 waveform((4.4±0.2)ms, (3.2±0.2)ms), duration ((12.1±0.5)ms, (10.3±0.2)ms), extinction time((7.8±0.2)ms, (6.9± 0.2)ms), volume under waveform ((7.3±0.2)ms, (4.3±0.2)ms) were significantly increased in the alcohol group ( t=16.100, - 11.840, -11.673, -35.576, all P<0.05). There were no significant differences in the amplitude, half width, rise time and decay time of Roff wave between the two groups ( t=-1.909, -0.910, -0.789, 1.462, all P>0.05). When JNJ16259685 was perfused on the brain surface of mice in alcohol group, the amplitude of field potential evoked by five blowing stimuli had no significant difference compared with that before administration (all P>0.05). When D-APV was perfused into the brain surface of mice in the alcohol group, the amplitude of P1 ((42.3±1.5) Mv)was significantly lower than that before administration ((101.1±0.9)mV) and after elution ((100.1±2.2) mV) ( t=106.762, - 69.605, both P<0.05), and the area under waveform of P1 ((42.6±1.3)%) was also significantly lower than that before administration ((100.6±1.6)%) and after elution ((97.6±2.2)%) ( t=88.862, -67.791, both P<0.05).The ratio of N2 / N1 (0.3±0.1) was significantly lower than that before administration (0.4±0.1) and after elution (0.3±0.1) ( t=2.242, 2.121, both P<0.05). When NMDA was perfused on the brain surface of mice in the control group, compared with before administration and after elution, the amplitude of P1 ((110.7±3.2) mV, (100.1±0.9) mV, (102.0±1.7) mV, t=-10.173, 7.669, both P<0.05), the area under the waveform of P1 ((127.9±3.5)%, (100.0±3.1)%, (115.0±5.3)%, t=-18.698, 6.447, both P<0.05), the ratio of N2 / N1 ((0.5±0.1), (0.3±0.1), (0.3±0.1), t=-5.669, 5.669, both P<0.05) were all significantly increased. When D-APV was perfused on the brain surface of mice in control group, the field potential evoked by blowing stimuli had no significant difference compared with that before administration and after elution (all P>0.05). Conclusion:Long-term alcohol intake significantly suppresses the synaptic transmission of excitatory glutamate in MF-GC, and enhances the inhibitory response mediated by GABAA receptor in cerebellar cortex. The inhibitory component is enhanced by NMDA receptor, but not by type 1 metabolic glutamate receptor.

Background and purpose: Checkpoint kinase 1 and 2 have been proposed to be potential therapeutic targets to sensitize cancers to radio- or chemo-therapeutics. However, little is known about whether Chk1/2 is also a suitable target for sensitizing cancers to curcumin. In the present study, we investigated effects of Chk1/2 siRNA on curcumin-induced apopotosis in hepatoma cell line Huh7 and evaluated the effectiveness of Chkl/2as a therapeutic target to potentiate human hepatoma to curcumin. Methods: Effect of curcumin on the cell cycle checkpoint-associated proteins was detected by Westem blot. The knockdown efficacy of Chk1/2 siRNA was measured by RT-PCR and Westem blot. Effect of Chk1/2 siRNA on curcumin-induced apoptosis in Huh7 cells was evaluated by DAPI staining. Effect of Chk1/2 siRNA on cell cycle distribution in curcumin-treated Huh7 cells was analyzed by flow cytometry. Results: Curcumin significantly inhibited phosphorylation of cell cycle checkpoint-associtaed proteins Chk1(S317), Cdc25C(S216) and Cdk1(Y15). Chk1 siRNA decreased Chk1 mRNA and protein by 95% and 92% and Chk2 siRNA decreased Chk2 mRNA and protein by 60% and 55% respectively as compared with negative control siRNA (P<0.01). Inhibition of Chk1, but not Chk2, increased apoptotic rate from (21.3±1.8)% to (29.5±2.6)% (P<0.05). Neither Chk1 nor Cbk2 siRNA had any impact on cell cycle distribution in Huh7 cells induced by curcumin. Conclusion: Chk1 siRNA sensitized Huh7 cells to curcumin-induced apoptosis, suggesting that Chk1 is a potential therapeutic target to sensitize human hepatoma to curcumin.

Objective To describe epidemiological characteristics of scalp psoriasis in China,and to determine its influencing factors through a hospital-based,multicenter and large-scale survey.Methods An epidemiological survey was conducted on patients with scalp psoriasis in 42 hospitals in 11 provinces and 4 municipalities.A questionnaire was designed to collect general and clinical information of patients,including clinical type,lesion distribution,psoriasis scalp severity index (PSSI),aggravating factors,influence on quality of life,treatment course,degree of satisfaction with treatment,etc.Participants were asked to fill out the questionnaire with the help of well-trained dermatologists.Data were processed with the EpiData software.The WPS system and Epi Info 5.0 statistics software were used for descriptive analysis of the data.Results Totally,3 901 patients participated this study,and 3 586 valid questionaires were obtained.The mean age at onset of scalp lesions was (27.40 ± 13.34) years,and the male to female ratio was 1.6∶1 with a mean PSSI score of 13.61 ± 12.31.The hairline of the forehead was the most frequently affected area with the constituent ratio of forehead psoriasis being 74.3％ (2 663/3 586).The duration of scalp psoriasis reached 3 to 6 months every year in 1 136 (31.7％) patients,and the area affected by scalp psoriasis was less than 25％ of the total surface area of the scalp in 1 649 (46％) patients.The most frequent clinical presentation was scaling (92.1％),followed by erythema (80.6％),itching(76.7％),bunchy hairs (39.9％) and hair loss(18.0％).Disease aggravation was most frequently associated with seasons (76.7％),emotions (47.4％),stress (47.1％) and fatigue (46.6％).The quality of life (especially social,outdoor and entertainment activities) was reported to be negatively influenced by this entity to different degrees in 2 529 (70.5％) patients.Of these patients,583 (17.8％) received combination therapy (topical and systemic),with glucocorticoid ointment (27.5％),calcipotriol scalp solution (22.7％) and glucocorticoid-containing solution (11.9％) being the most commonly used topical drugs; only 38.6％ complied with medication requirements and doctors' advice for 3 to 5 weeks,and 35.2％ believed that the primary reason for poor compliance was unsatisfactory response to drugs.It was considered that an ideal drug for the treatment of scalp psoriasis should be highly effective (50.3％),safe (17.8％) and easy to apply (11％) with a rapid onset of action(11.9％).Conclusions Scalp psoriasis has a predilection for the hairline of the forehead with scaling as the main clinical presentation.Winter and spring seasons appear to be the most common aggravating factor of scalp psoriasis.The quality of life is negatively influenced to different degrees in many patients with scalp psoriasis.Topical corticosteroids plus non-hormonal drugs should be the first choice for the treatment of scalp psoriasis.Patients consider that the ideal drugs for the treatment of scalp psoriasis should be effective,safe,and easy to apply.

Objective To observe the efficacy and toxicities of RF transparent heating (RTH) combined with transcatheter hepatic arterial chemoembolization (TACE) in the treatment of advanced primary hepatic carcinoma. Methods In a randomized manner, 69 patients with advanced primary hepatic carcinoma were divided into two groups: study group (TACE+RTH) 34 cases and control group (TACE alone) 35 cases, the control group were treated with DDP 80mg, FU 1000mg and E-ADM 60mg, E-ADM was used with iodized oil embolism 10ml. Results The total effective rate in the near future were 70.59% and 45.71%, the overall survival rates of 0.5, 1.0, 1.5, 2.0 years were 82.35%, 73.53%, 58.82%, 38.24% in study group and 74.29%, 75.14%, 45.71%, 22.86% in control group, respectively. Toxicities were similar comparing with the two groups. Conclusions RTH combined with TACE in the treatment of advanced primary hepatic carcinoma is better than TACE alone, at the same time TACE +RTH method is no increasing toxicity and is an effective safe combined one.

Objective To explore the association of serum soluble Klotho (sKlotho) with nonfatal cardiovascular disease (CVD) and all-cause/CVD mortality in maintenance hemodialysis (MHD) patients.Methods A total of 132 MHD patients admitted during October 2011 were enrolled.Serum sKlotho was measured by ELISA.Demographic data,including age,gender and comorbid conditions,were obtained from their medical histories,and parameters including calcium,phosphorus and albumin were assessed.The occurrence time of nonfatal CVD and all-cause mortality were recorded during the 60 months follow-up.MHD patients were categorized into four groups according to the quartiles of sKlotho:group Ⅰ (sKlotho ＜ 361.34 ng/L),group Ⅱ (361.34 ng/L≤sKlotho＜ 398.81 ng/L),group Ⅲ (398.81 ng/L≤sKlotho＜445.99 ng/L) and group Ⅳ (sKlotho≥445.99 ng/L).Spearman correlation analysis and binary Logistic regression analysis were used to test the association between sKlotho and nonfatal CVD events.The impacts of sKlotho on all-cause mortality and CVD mortality were assessed by Kaplan-Meier method with log-rank test.Cox regression model was applied to evaluate the effect of sKlotho on MHD patients outcomes.Results All 132 MHD patients had sKlotho ranging from 304.02 ng/L to 550.62 ng/L.And 87 patients suffered from nonfatal CVD,with 192 episodes of nonfatal CVD during the follow-up period.The sKlotho had negative correlations with coronary artery disease (r=-0.286,P=0.001),congestive heart failure (r=--0.190,P=0.029),cerebrovascular accident (r=-0.240,P=0.006) and peripheral arterial occlusion (r=-0.243,P=0.005).The sKlotho were risk factors of coronary artery disease (OR=0.989,P=0.023) and peripheral artery occlusion (OR=0.988,P=0.046).35 patients died in the follow-up period,including 27 death from CVD.The all-cause mortality and CYD mortality rates were significantly different among four groups (P=0.036,P=0.047).Survival rates of all-cause death and CVD death varied among four groups (x2=8.076,P=0.044;X2=7.866,P=0.049).Patients in group Ⅳ had higher survival rates of allcause death and CVD death than those in group Ⅰ and group Ⅱ (all P ＜ 0.05).Multivariate Cox regression analyses revealed diabetes and age were independent risk factors for all-cause mortality and CVD mortality (all P ＜ 0.05),but sKlotho was not associated with the poor prognosis (HR=0.996,P=0.256;HR=0.996,P=0.287).Conclusions Patients with lower sKlotho have worse nonfatal CVD ratio,especially coronary artery disease and peripheral arterial occlusion.Reduced serum sKlotho is associated with all-cause and CVD mortality,but sKlotho is still not a predictive indicator of prognosis of MHD patients.

Purpose To explore the biological significance of BCL-6 and ZEB2 in invasion,metastasis and prognosis of breast cancer.Methods The expressions of BCL-6,ZEB2 protein and mRNA were detected respectively in 228 cases of breast cancer and 80 cases of breast benign lesions by immunohistochemical SP two-step staining and situ hybridization.Result The expression levels of BCL-6,ZEB2 protein and mRNA in breast cancer tissues were significantly higher than in breast benign lesions (P ＜ 0.05).The expressions of BCL-6 was positively correlated with tumor size,lymphatic metastasis,histological grade,TNM staging and HER-2 expression (P ＜ 0.05).The expressions of ZEB2 was positively correlated with tumor size,lymphatic metastasis,TNM staging and HER-2 expression (P ＜ 0.05).The overall survival and relapse-free survival of BCL-6 and ZEB2 positive expression were significantly less than the negative expression (P ＜ 0.01).Conclusion The BCL-6 and ZEB2 are closely correlated with the evolution process of breast cancer,which may become important means for monitoring and warning the metastasis,invasion,and prognosis of breast cancer.
