Objective: To investigate the hepatorenoprotective effects of Origanum vulgare L. against finasteride-induced oxidative injury in the liver and kidney of mice. Methods: Liquid chromatography-electrospray ionization-tandem mass spectrometry (LC-ESI/MS) analysis was utilized to yield a fingerprint of Origanum vulgare polyphenolic constituents. Thirty BALB/c mice received 0.5 mL/day distilled water, finasteride (25 mg/kg/day for 10 d), and 100, 200, or 400 mg/kg/day finasteride + Origanum vulgare extract with 6 mice per group for five weeks. On day 36, liver and kidney function as well as pro-and antiinflammatory (IFN-γ, IL-12, IL-6, TNF-α, IL-1β, and IL-10) cytokines were measured. The total antioxidant status, nitric oxide (NO), and malondialdehyde levels as well as the activities of NO synthase and catalase were also evaluated. Histopathological study was conducted to assess the effect of Origanum vulgare extract on finasteride-induced renal and hepatic toxicities. Results: Twenty-five major polyphenolic compounds were identified in the Origanum vulgare extract by LC-ESI/MS. Origanum vulgare extract, especially at 200 and 400 mg/kg/day doses, significantly improved liver and kidney biochemical indices, decreased inflammatory cytokines, increased total antioxidant status and NO synthase and catalase activities, as well as decreased plasma NO and malondialdehyde levels in a dose-dependent manner as compared to the finasteride group. Histopathological results further confirmed the protective effect of Origanum vulgare extract. Conclusions: Origanum vulgare extract ameliorates finasteride-induced hepatic and renal biochemical and histopathological alterations, and restores antioxidant/oxidant balance.

OBJECTIVE: To investigate the impacts of two herbal preparations for human immunodeficiency virus/aquired immune deficiency syndrome (HIV/AIDS) patients, Shenling Fuzheng Capsule (, SLFZC) and Qingdu Capsule (, QDC), on the efficacy of highly active antiretroviral therapy (HAART). METHODS: HIV/AIDS patients met the criteria were all enrolled in a 1-year cohort study, in which patients receiving HAART alone were designated as Group A, those receiving HAART in combination with SLFZC were designated as Group B, and those receiving HAART in combination with QDC were designated as Group C, 100 cases in each group. The dose of SLFZC was 1.48 g (4 capsules), 3 times daily, and QDC 1.56 g (4 capsules), 3 times daily. T cell subsets, HIV RNA and HIV-1 drug resistance were detected at enrollment and 1 year after treatment. Patients were followed up every 3 months, during which side-effects and other clinical data were recorded. RESULTS After 1-year treatment, the median increment in CD counts was 165.0, 178.0 and 145.0 cells/μL for Group A, B and C, respectively. HIV RNA was undetectable in 94% of patients in Group A, 96% in Group B and 92% in Group C. There were no differences regarding the increment in CD counts, HIV RNA and frequency of HIV-1 drug resistance mutations. Two of the 14 suspected side-effect symptoms, i.e. fatigue and dizziness, were lower in Groups B and C than in Group A (P<0.05, respectively) CONCLUSIONS: SLFZC and QDC do not have a negative impact on immunological and virological response to HAART; however, these preparations are not as potent in reducing HAART-associated side-effects as anticipated.

BACKGROUND: Psoriasis is a chronic inflammatory skin disease, affecting about 0.6% of the Chinese population. Many patients are not well controlled by conventional treatments, thus there is need for new treatment regimens. In this study, we assessed the efficacy and safety of secukinumab in Chinese patients with moderate to severe plaque psoriasis. METHODS: This study was a 52-week, multicentre, randomized, double-blind, placebo-controlled, parallel-group, Phase 3 trial. A sub-population of study participants (≥18 years) of Chinese ethnicity were randomized to receive subcutaneous injections of 300 or 150 mg secukinumab, or placebo. The co-primary endpoints were psoriasis area severity index (PASI) 75 and Investigator's Global Assessment (IGA) 0/1 at Week 12. RESULTS: A total of 441 Chinese patients were enrolled in this study. Co-primary outcomes were achieved; 300 and 150 mg secukinumab were superior to placebo as shown in the proportion of patients that achieved PASI 75 (97.7% and 87.2% vs. 3.7%, respectively; P < 0.001), and IGA 0/1 (82.3% and 69.7% vs. 2.7%; P < 0.001) at Week 12. Treatment efficacy was maintained until Week 52. There was no increase in overall adverse events with secukinumab relative to placebo throughout the 52-week period. CONCLUSION: Secukinumab is highly effective and well tolerated in Chinese patients with moderate to severe plaque psoriasis.

OBJECTIVETo reduce health-related threats of heat waves, interventions have been implemented in many parts of the world. However, there is a lack of higher-level evidence concerning the intervention efficacy. This study aimed to determine the efficacy of an intervention to reduce the number of heat-related illnesses.

METHODSA quasi-experimental design was employed by two cross-sectional surveys in the year 2014 and 2015, including 2,240 participants and 2,356 participants, respectively. Each survey was designed to include one control group and one intervention group, which conducted in Licheng, China. A representative sample was selected using a multistage sampling method. Data, collected from questionnaires about heat waves in 2014 and 2015, were analyzed using a difference-in-difference analysis and cost effectiveness analysis. Outcomes included changes in the prevalence of heat-related illnesses and cost-effectiveness variables.

RESULTSRelative to the control participants, the prevalence of heat-related illness in the intervention participants decreased to a greater extent in rural areas than in urban areas (OR=0.495 vs. OR=1.281). Moreover, the cost-effectiveness ratio in the intervention group was less than that in the control group (US$15.06 vs. US$15.69 per participant). Furthermore, to avoid one additional patient, the incremental cost-effectiveness ratio showed that an additional US$14.47 would be needed for the intervention compared to when no intervention was applied.

CONCLUSIONThe intervention program may be considered a worthwhile investment for rural areas that are more likely to experience heat waves. Meanwhile, corresponding improving measures should be presented towards urban areas. Future research should examine whether the intervention strategies could be spread out in other domestic or international regions where heat waves are usually experienced.

INTRODUCTIONHepatocellular adenomas (HCAs), with a risk of malignant transformation into hepatocellular carcinoma (HCC), classically develop in young women who are taking oral contraceptives. It is now clear that HCAs may also occur in men. However, it is rarely reported that HCAs with malignant transformation occur in male patients with non-cirrhotic livers. This study aimed to characterize the malignancy of HCAs occurring in male patients.

METHODSAll patients with HCAs with malignant transformation who underwent hepatectomy at the Cancer Institute and Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College between January 1, 1999 and December 31, 2011 were enrolled in the study. The clinical characteristics as well as radiologic and pathologic data were reviewed.

RESULTSHCAs with malignant transformation were observed in 5 male patients with non-cirrhotic livers, but not in female patients. The alpha-fetoprotein (AFP) levels were higher in patients with HCAs with malignant transformation than in patients with HCAs without malignant transformation. The diameters of the tumors with malignant transformation were larger than 5 cm in 3 cases and smaller than 5 cm in 2 cases. The 5 patients were all alive without recurrence by the end of the study period. The disease-free survival times of the 5 patients were 26, 48, 69, 69, and 92 months.

CONCLUSIONOur results indicate that resection would be advised even if the presumptive diagnosis is adenoma smaller than 5 cm in diameter, especially in male patients.

Objective To measure the transcription level of thermostable direct hemolysin gene (TDH)in 24 strains of Vibrio parahaemolyticus.Methods Total RNA was extracted from strains of Vibrio parahaemolyticus which were isolated from patients,seafood and environment.The RNA was proved TDH positive with routine PCR method;then the real -time fluorescent quantitative PCR was carried out to obtain the cycle of threshold (Ct)of THD and internal standard of 16s rRNA.Transcription level of THD compared with 16s rRNA was designated as ΔCt which was calculated as Ct value of THD minus Ct value of 16s rRNA.Results Ct values of THD,16s rRNA and the difference between them of the 24 strains was 18.04 ~25.95,8.30 ~10.93 and 8.28 ~15.34 respectively.The difference between the maximum and the minimum of ΔCt was 7.06;the highest transcription level was 133 (ΔΔCt =27.06 )times of the lowest one.Conclusion A great difference of transcription level of THD in Vibrio parahaemolyticus has been proved and further study is needed to clarify the possible molecular mechanisms and relationship between the transcription level of THD and pathogenic mechanism.

OBJECTIVETo study the relationship between the change of coagulation and the clinicopathologic characteristics in patients with gallbladder cancer.

METHODSThe 64 gallbladder cancer patients (GBC group) and 60 cholecystitis patients (control group) had been reviewed from January 2007 to June 2013. The prothrombin time (PT), activated partial thromboplastin time (APTT), fibrinogen (Fib), and thrombin time (TT) had been measured and compared between patients of GBC group and control group. The relationship of coagulation function and prognosis were analyzed.

RESULTSCompared with control group, APTT in GBC group ((29.0 ± 4.2) s) was significantly shortened (t = -4.265, P = 0.000) and PT ((11.5 ± 1.4) s), TT ((15.3 ± 3.5) s), Fib ((4.1 ± 0.9) g/L) were significantly increased in GBC group (t = 2.521, 4.147 and 4.365, all P < 0.05). The level of Fib was higher in patients with medium or poor-differentiated tumor cells (F = 4.069, P = 0.022), lymph metastasis (t = 2.640, P = 0.010) and advanced staging (II-IV) (t = 3.003, P < 0.01) than those of well-differentiated, non-lymph metastasis and early staging (0-I). The ratio of gallbladder cancer with hyperfibrinogenemia (32/64) was significantly higher than control group (11/60, χ(2) = 13.709, P < 0.01). In GBC group, compared with normal Fib patients, hyperfibrinogenemia patients showed significantly difference in clinicopathologic characteristics (χ(2) = 5.851-10.573, P < 0.05). The average survival period of hyperfibrinogenemia patients and normal Fib patients were 8.63 months and 16.73 months. The 1-, 3-year survival rate of patients with hyperfibrinogenemia were significantly lower than those with normal Fib (64.7%, 14.9% vs. 74.9%, 21.1%, P < 0.05).

CONCLUSIONPreoperative plasma level of Fib might be a new promising biomarker in patients with gallbladder cancer for evaluating disease progression and prognosis.

OBJECTIVETo evaluate the effect of preoperative transarterial chemoembolization (TACE) on hepatocellular carcinoma located in caudate lobe.

METHODSTotally 29 cases of caudate lobe hepatocellular carcinoma admitted from January 2001 to December 2010 were analyzed retrospectively. Among the 29 patients, 23 were male and the other 6 were female. The median age was 52 years. According to receiving preoperative TACE or not, the 29 cases were divided into two groups: preoperative TACE plus surgery (group A, n = 11) and surgery only (group B, n = 18). The surgical results and long-term survival were compared between two groups.

RESULTSAfter TACE, the diameter of the tumour reduced by over 33.3% in 3 patients, 10.0% to 33.3% in 6 patients, and less than 10.0% in 2 patients. The duration of surgery and intraoperative blood loss in group A were (298 ± 39) minutes and (1031 ± 310) ml, respectively. The duration of surgery and intraoperative blood loss in group B were (281 ± 54) minutes and (868 ± 403) ml, respectively. No significant difference was found in terms of these two groups (t = 1.006, P = 0.324; t = 1.223, P = 0.232). In addition, 6 cases in group A developed complications and 4 cases in group B did so. Only one patient died because of postoperative complication, and this patient belonged to group A. No significant difference was found between two groups (χ(2) = 0.028, P = 0.868; χ(2) = 0.633, P = 0.426). The 5-year survival rate was 56.8% in group A and 34.9% in group B. The difference did not reach significant difference (P = 0.132).

CONCLUSIONSFor hepatocellular carcinoma located in caudate lobe, preoperative TACE does not significantly increase the surgical difficulty and impair the safety. In addition, preoperative TACE has the tendency to provide benefit to long-term survival.

OBJECTIVETo investigate the protective effects of the natural medicinal monomer isopsoralen (ISR) with estrogenic activity against oxidative damage in human lens epithelial cells B3 (HLE-B3) caused by hydrogen peroxide (H(2)O(2)) and to pursue the possible mitochondrial proteomic regularity of the protective effects.

METHODSHLE-B3 cells were treated with H(2)O(2) (300 μ mol/L), β-estradiol (E(2): 10(-8) mol/L) and H(2)O(2), ISR (10(-5) mol/L) and H(2)O(2), or left untreated. Altered expressions of all mitochondrial proteins were analyzed by protein array and surfaceenhanced laser desorption ionization time of flight mass spectrometry (SELDI-TOF-MS). The mass/charge (m/z) ratios of each peak were tested by the Kruskal-Wallis rank sum test, and the protein peak value of the m/z ratio for each treatment by pair comparison was analyzed with the Nemenyi test.

RESULTSH(2)O(2) up-regulated the expressions of two protein spots (with m/z of 6532 and 6809). E(2) mitigated the oxidative damage, and the expression of one protein spot (m/z 6532) was down-regulated. In contrast, ISR down-regulated both of protein spots (m/z 6532 and 6809).

CONCLUSIONSISR could effectively inhibit H(2)O(2)-induced oxidative damage in HLE-B3 cells. The protein spot at m/z of 6532 might be the target spot of ISR against oxidative damage induced by H(2)O(2).
