INTRODUCTION: Haze is a recurrent problem in Southeast Asia. Exposure to haze is linked to ophthalmic, respiratory and cardiovascular diseases, and mortality. In this study, we investigated the role of demographic factors, knowledge and perceived risk in influencing protective behaviours during the 2013 haze in Singapore. METHODS: We evaluated 696 adults in a cross-sectional study. Participants were sampled via a 2-stage simple random sampling without replacement from a large residential district in Singapore in 2015. The questionnaire measured the participant's knowledge, perceived risk and behaviours during the Southeast Asian haze crisis in 2013. Reliability and validity of the questionnaire were assessed using comparative fit index (≥0.96) and root mean square error of approximation (≤0.05). We performed structural equation modelling to examine the relationship between the hypothesised factors and protective behaviours. RESULTS: More than 95% of the individuals engaged in at least 1 form of protective behaviour. Knowledge was strongly associated with protective behaviours via direct effect (β=0.45, 95% CI 0.19-0.69, CONCLUSION Knowledge was associated with protective behaviours, suggesting the importance of public education. Efforts should target those of lower education level and smokers. The wearing of N95 masks correlates with uptake of other protective behaviours.

BackgroundFunctional dyspepsia (FD) is a common upper gastrointestinal disorder worldwide, but the current treatments for FD are still unsatisfactory. The aims of this study were to investigate the efficacy and safety of Qi-Zhi-Wei-Tong granules in patients with postprandial distress syndrome (PDS)-predominant FD.

MethodsThe study was conducted as a randomized, double-blinded, multicenter, placebo-controlled design in 197 patients with PDS. All participants received placebo treatment for 1 week. Patients whose total symptom score decreased by <50% after the placebo treatment were recruited into the 4-week treatment period, in which they were randomly assigned to be treated with either Qi-Zhi-Wei-Tong granules or placebo. The patients were then followed for 2 weeks without any treatment. Dyspeptic symptoms were scored at weeks 2 and 4 during the random treatment period and 2 weeks after the treatment. Anxiety and depression symptoms were also scored and compared.

Results(1) The total effective rates in the Qi-Zhi-Wei-Tong granules group at weeks 2 and 4 during the random treatment period and 2 weeks after treatment were all significantly higher than those in the placebo group (38.82% vs. 8.75%, P < 0.001; 69.14% vs. 16.25%, P < 0.001; 77.65% vs. 21.25%, P < 0.001). (2) The total dyspeptic symptoms scores in the Qi-Zhi-Wei-Tong granules group at weeks 2 and 4 and 2 weeks after treatment were significantly lower than those in the placebo group. (3) The severity and frequency of each dyspeptic symptom at weeks 2 and 4 and the follow-up period were all significantly lower than those in the placebo group. (4) The anxiety scores in the Qi-Zhi-Wei-Tong granules group were significantly lower than those in the placebo group. (5) Qi-Zhi-Wei-Tong granules did not have more adverse effects than the placebo.

ConclusionQi-Zhi-Wei-Tong granules offer significant symptomatic improvement in PDS with no more adverse effects than placebo.

BACKGROUND/AIMS: Previous studies have revealed that mast cells (MCs) may activate the protease-activated receptors and release of neuropeptides involved in the pathogenesis of irritable bowel syndrome (IBS). The levels of protease-activated receptor 2 (PAR-2) and tryptase can contribute to understanding the pathogenesis of IBS. METHODS: Colonoscopic biopsies were performed of 38 subjects (20 with IBS-diarrhea [IBS-D], eight with IBS-constipation [IBS-C], and 10 healthy volunteers). The mRNA and protein levels of tryptase and PAR-2 were assessed by real-time PCR and Western blot. The levels of vasoactive intestinal peptide (VIP), substance P (SP), and calcitonin gene-related peptide (CGRP) were measured by immunohistochemistry, and MCs were counted by toluidine blue staining. RESULTS: Significant increases in the mRNA expression of tryptase (p<0.05, IBS-D, IBS-C vs control) and PAR-2 (p<0.05, IBS-D, IBS-C vs control) and in the tryptase protein level (p<0.05, IBS-D, IBS-C vs control) were detected in IBS. Elevations of MCs, CGRP, VIP and SP (p<0.05, IBS-D vs control) were observed for IBS-D only. CONCLUSIONS: Tryptase levels may upregulate the function of PAR-2, resulting in the release of neuropeptide and they were correlated with clinical symptoms associated with IBS.

OBJECTIVETo investigate the impact of infertility on men's self-esteem, self-confidence, sexual satisfaction and overall relationship with their spouses.

METHODSUsing Self-Esteem and Relationship questionnaire (SEAR), we conducted an investigation among 253 infertile men and 52 fertile male controls. We divided the infertile men into four subgroups according to their perceived causes of infertility: male (M) factors, female (F) factors, both M and F factors, and unknown factors, and compared the SEAR scores among different groups.

RESULTSIn the infertile men, the total SEAR score was significantly higher in those with < 3 years than in those with > or = 3 years of infertility duration (75.50 +/- 17.05 vs 68.66 +/- 17.19, P < 0.05) and so was it in those with above-high-school than in those with high-school or lower education background (81.42 +/- 13.99 vs 67.61 +/- 17. 8, P < 0.01), but showed no significant difference between the > or = 30- and < 30-year-olds (71.77 +/- 17.42 vs 72.74 +/- 18.38, P > 0.05). The total SEAR scores in the M factor, M & F factor, unknown factor and F factor groups were 65.69 +/- 18.68, 68.52 +/- 17.68, 74.85 +/- 15.19 and 83.21 +/- 12.61, respectively, with significant differences between the first two and the latter two groups (P < 0.05), as well as between the unknown factor and F factor groups (P < 0.05). In the fertile male controls, the total SEAR score and subdomain scores on sexual relationship, self-confidence, self-esteem and overall relationship were 90.04 +/- 9.85, 88.40 +/- 10.74, 92.23 +/- 9.41, 91.95 +/- 10.67 and 90.38 +/- 14.14, respectively, all remarkably higher than in the M factor, M&F factor and unknown factor groups of the infertile men after adjustment of their infertility duration and education levels (P < 0.05).

CONCLUSIONInfertility reduces men's self-esteem, self-confidence, sexual satisfaction and relationship with their spouses, and the degree of its impact is correlated with the patients' infertility duration and education level.

OBJECTIVETo evaluate the impact of the factors of perceived male infertility on men's penile erectile function.

METHODSUsing the 5-item version of the International Index of Erectile Function (IIEF-5), we investigated the penile erectile function among 245 infertile men (infertility group) and another 52 males having physical checkup for planned conception (checkup group), the former further divided into four subgroups according to the factors of infertility: male factor, female factor, bilateral factor, and unknown factor. We compared the total and item scores of IIEF-5 among different groups.

RESULTSMild or mild-moderate ED was found in 50.61% of the infertile men, with a total IIEF-5 score of 21.24 +/- 2.58. The total and item scores of IIEF-5 were markedly higher in the male factor than in the female factor subgroup (P < 0.01), but with no significant difference between the male factor subgroup and the bilateral and unknown factor subgroups (P > 0.05), except the score on confidence. The scores were significantly lower in the bilateral and unknown factor subgroups than in the female factor subgroup (P < 0.05), with no remarkable difference between the former two. In the infertility group, the total and item scores of IIEF-5 were markedly higher in those with education above high school than in those with high school or lower education (P < 0.01), but not correlated with age and infertility duration. After adjustment for education background, the total IIEF-5 score and the scores on confidence and satisfaction were significantly lower in the infertility than in the checkup group (P < 0.05), and 15.38% of the men in the latter group had mild ED, dramatically lower than in the former (P < 0.01).

CONCLUSIONPerceived infertility may cause ED in males, and a higher incidence rate is associated with lower education background of the men.

Objective To analyze the death causes of 345 cases with HIV/AIDS in Guangdong area.Methods The situations of 345 hospitalized death cases with HIV/AIDS were conducted by retrospective analysis.Results (1)There were total 3406 hospitalized cases with HIV/AIDS in a hospital from January 2001 to December 2011 and 345 cases died,the fatality rate was 10.13％.Since 2005 the introduction of free anti-viral treatment,the fatality rate of HIV/AIDS declined.The fatality rate of the patients whose CD4+ T lymphocyte counts ＜ 200 cells/μl was 14.61％ (299/2046) and it was significantly higher than that of patients whose CD4 + T lymphocyte counts ≥200 cells/μl (P ＜0.01).(2) 99.42％ of the death cases had more than one kind of opportunistic infections (OI) and there were 924 cases of OI totally.84.64％ of OI related to the death directly.Fungal infection was the most common in OI,followed by bacterial infection.Most OI occurred in the lungs,mouth,other systemic disseminated diseases,gastro intestine,central nerver system,septicemia,skin.The AIDS defining opportunistic infections such as several pneumonia,disseminated penicilliosis marneffei and CNS infections accounted for 29.65％.Other factors that caused HIV/AIDS death included opportunistic tumors,HIV related disease and non AIDS-related disease accounted for 15.36％.No accepted effective highly active antiretroviral therapy (HARRT)also constituted factors of death.Among cases which accepted HARRT treatment,only 6.96％ had the period of treatment over three months.Conclusion The fatality rate of end-stage AIDS patients was high and the opportunistic infections was the most important cause of death.Early diagnosis and treatment for opportunistic infections,timely effective HARRT were the key to improve the quality of life of AIDS patients.

OBJECTIVETo evaluate the efficacy of nimotuzumab combined with palitaxel liposome and carboplatin (LP) regimen for treatment of advanced non-small cell lung cancer (NSCLC), and to observe the changes of tumor markers and toxicities in the treatment. METHODS Forty-one patients with advanced NSCLC were randomly divided into 2 groups: 21 patients in the observation group were treated with nimotuzumab (200 mg per week for 6 weeks), palitaxel liposome 160 mg/m2 and carboplatin (AUC = 6). 20 patients in the control group were given LP regimen. Each group completed two cycles of chemotherapy. The level of tumor markers (CEA, CYFR21-1 and NSE) and toxicities were checked at one week before and after the treatment. Thoracic CT examinations were taken before treatment and at the fourth week and eighth week after treatment.

RESULTSIn the observation group, there were 2 cases of CR, 7 cases of PR, 9 cases of SD and 3 cases of PD. The objective response rate (RR) was 42. 9% in the observation group. In the control group, there were 1 case of CR, 6 cases of PR, 8 cases of SD and 5 cases of PD, with a RR of 35.0% in this group. There was no significant difference in the RR between the two groups (P = 0.751). The time to progression (TIP) was 6. 9 months in the observation group and 5. 7 months in the control group, with a significant difference (P = 0.027). The levels of NSE decreased significantly in both groups and showed a significant difference (P = 0.039). The levels of CEA and CYFRA21 in both groups were decreased after treatment, but did not show a significant difference before and after treatment, respectively. Except 3 cases had I-II skin toxicities on the faces in the observation group, there was no significant difference in toxicities between the two groups.

CONCLUSIONNimotuzmab combined with LP regimen shows a synergistic effect, can increase the efficacy and prolong TFP in advanced NSCLC patients. The toxicities are mild and tolerable.
