OBJECTIVETo study albumin adduct with naphthalene metabolites, namely 1,2-naphthoquinone (1,2-NPQ) and 1,4-naphthoquinone (1,4-NPQ), as a potential biomarker for intermediate/long-term exposure to polycyclic aromatic hydrocarbons (PAH) in coke oven workers.
METHODSTwenty-eight coke oven workers and 22 control workers were recruited from a cokery. Spot urine and venous blood samples were collected from the workers after four continuously working days and personal information was obtained by questionnaire. Plasma albumin adduct was detected with gas chromatography-mass spectrometry.
RESULTSAlbumin adduct with 1,2- & 1,4-NPQ (1,2-NPQ and 1,4-NPQ), respectively, were detected in all coke oven workers and controls. Median plasma level of 1,2-NPQ-Alb in coke oven workers was significantly higher than that in controls (76.6 pmol/g vs. 44.9 pmol/g, P < 0.01). However, there was no significant difference in plasma median level of 1,4-NPQ-Alb between the two groups (48.6 pmol/g vs. 44.2 pmol/g, P > 0.05). Plasma level of 1,2-NPQ-Alb was significantly higher than that of 1,4-NPQ-Alb in coke oven workers. Urine levels of naphthalene, 1-naphthol, 2-naphthol and 1-pyrenol in coke oven workers correlated significantly with their plasma level of 1,2-NPQ-Alb (Pearson coefficient of correlation greater than 0.371, P < 0.01), but did not do significantly with 1,4-NPQ-Alb.
CONCLUSIONPlasma level of 1,2-NPQ-Alb could effectively reflect their magnitude of personal internal dose of exposure to air PAH, so it could be used as a potential biomarker to evaluate their intermediate/long-term exposure to PAH in coke oven workers.

We report a case of 61-yr-old man with stable psoriasis who progressively developed generalized pustular eruption, erythroderma, fever, and hepatic dysfunction following oral terbinafine. Skin biopsy was compatible with pustular psoriasis. After discontinuation of terbinafine and initiating topical corticosteroid and calcipotriol combination with narrow band ultraviolet B therapy, patient's condition slowly improved until complete remission was reached 2 weeks later. The diagnosis of generalized pustular psoriasis (GPP) induced by oral terbinafine was made. To our knowledge, this is the first report of GPP accompanied by hepatic dysfunction associated with oral terbinafine therapy.

OBJECTIVETo explore the rate of compliance, influencing factors and the safety of patients with onychomycosis under treatment of oral antifungal agents.
METHODSAccording to the scoring clinical index of onychomycosis (SCIO), 330 patients with onychomycosis, their target nail's integral of the SCIO were calculated and randomly divided into three groups under the baseline of the SCIO integral range. Patients were treated with intermittent pulse itraconazole (A group), continuous terbinafine (B group) and intermittent terbinafine (C group) respectively. Self-administered questionnaire was applied in the survey on every onychomycosis patient.
RESULTSThe average rate of compliance was 55.15%. The cure rate for those compliance with doctors' order was 89.01%, while it was only 30.41% for those noncompliant patients The overall non-compliant rate was 44.85%. Among the noncompliant ones, 29.73% were worried about the side effects of medicine, 22.30% thought that they had already been cured, 15.54% was due to economic reasons and 12.16% could not bear the side effects of medicine. It was found that the compliant rates were significantly correlated to ageing, position of the target nails, the integral of the SCIO and the therapy scheme (P < 0.05), while no significant correlations were seen between male and female, culture degree and course (P > 0.1). The frequency of adverse incident of A, B, C groups were 22.73%, 21.43%, 23.15% respectively, but without statistical significance (P > 0.1). Majority of the adverse incidents happened during the first month of therapy but were mild and reversible.
CONCLUSIONOur results showed that the overall compliance was low which exerted a significant influence on the curative effect of onychomycosis patients. Factors as ageing, position of the target nail, integral of the SCIO and the therapy scheme had an influence on the compliant rate. When treating onychomycosis with oral itraconazole, the results seemed to be just as safe as when using terbinafine.

PURPOSE: Cinacalcet is effective for treating refractory secondary hyperparathyroidism (SHPT), but little is known about the response rates and clinical factors influencing the response. MATERIALS AND METHODS: A prospective, single-arm, multi-center study was performed for 24 weeks. Cinacalcet was administered to patients with intact parathyroid hormone (iPTH) level greater than 300 pg/mL. Cinacalcet was started at a dose of 25 mg daily and titrated until 100 mg to achieve a serum iPTH level <300 pg/mL (primary end point). Early response to cinacalcet was defined as a decrease of iPTH more than 50% within one month. RESULTS: Fifty-seven patients were examined. Based on the magnitude of iPTH decrease, patients were divided into responder (n=47, 82.5%) and non-responder (n=10, 17.5%) groups. Among the responders, 38 achieved the primary end point, whereas 9 patients showed a reduction in serum iPTH of 30% or more, but did not reach the primary end point. Compared to non-responders, responders were significantly older (p=0.026), female (p=0.041), and diabetics (p<0.001). Additionally, early response was observed more frequently in the responders (30/47, 63.8%), of whom the majority (27/30, 90.0%) achieved the primary end point. Multivariate analysis showed that lower baseline iPTH levels [odds ratio (OR) 0.96, 95% confidence interval (CI) 0.93-0.99], the presence of diabetes (OR 46.45, CI 1.92-1125.6) and early response (OR 21.54, CI 2.94-157.7) were significant clinical factors affecting achievement of iPTH target. CONCLUSION: Cinacalcet was effective in most hemodialysis patients with refractory SHPT. The presence of an early response was closely associated with the achievement of target levels of iPTH.

OBJECTIVESTo evaluate the clinical efficacy and safety of Naftopidil tablet in treating benign prostatic hyperplasia.
METHODSEighty BPH patients were divided into two groups randomly by double-blind, double-simulated and active control parallel study trials. Forty patients in treatment group were given Naftopidil tablet 25 mg, p.o., qn for 42 days, while 40 patients in control group were given Tamsulosin 0.2 mg, p.o., qn for 42 days. Statistical analysis was given from 77 cases in the groups. Estimation of the efficacy was done by the change of major indexes include international prostate symptom score (IPSS), maximum flowrate (Qmax) and secondary indexes such as quality of life (QOL), residual urine (Ru) and volume of prostate (V).
RESULTSThe changes of IPSS, Qmax, QOL had significant difference between two groups before and after treatment(P < 0.05). The change of Ru had no significant difference between two groups before and after treatment (P > 0.05) while there was significant difference between two groups after six-week treatment(P < 0.05). The change of V had no significant difference (P > 0.05). The adverse reactions in both groups were mild, and there was no significant difference between two groups(P > 0.05).
CONCLUSIONSNaftopidil tablet was safe and effective in treating benign prostatic hyperplasia.

OBJECTIVETo investigate the efficacy and adverse effects of dapoxetine in the treatment of premature ejaculation.
METHODSWe randomly assigned outpatients with premature ejaculation in the proportion of 2:1 to receive 30 mg dapoxetine on demand (n =78) or 50 mg sertraline qd for one month (n = 39). Follow-up was accomplished in 95 cases, 63 in the dapoxetine group and 32 in the sertraline group. We recorded the intravaginal ejaculatory latency time (IELT), clinical global impression of change (CGIC) score, and adverse reactions of the patients and compared them between the two groups.
RESULTSIELT was significantly increased in both the dapoxetine (from [0.87 ± 0.31] to [2.84 ± 0.68] min, P < 0.05) and the sertraline group (from [0.84 ± 0.28] to [2.71 ± 0.92] min, P < 0.05) after medication. Based on the CGIC scores in premature ejaculation, the rate of excellence or effectiveness was 36.5% in the dapoxetine and 37. 5% in the sertraline group, and the rate of improvement was 63.5% in the former and 71.9% in the latter. The incidence rates of dizziness, nausea, headache, and diarrhea were slightly higher (P > 0.05) while those of fatigue, somnolence, and dry mouth significantly higher (P < 0.05) in the sertraline than in the dapoxetine group.
CONCLUSIONOn-demand oral medication of dapoxetine is effective and well-tolerated for the treatment of premature ejaculation.
