BACKGROUND： Demanding profession has been associated with poor psychological health due to multiple factors such as overworking hours and night shifts. This study is to determine prevalence and associated factors of depression, anxiety and stress among medical officers working at emergency department in Malaysian ***： A cross-sectional study was conducted on 140 emergency department medical officers working at general hospitals from seven Malaysia regions. They were randomly selected and their depression, anxiety and stress level were measured by the 21-item Depression, Anxiety, Stress Scale. RESULTS： The highest prevalence was anxiety （28.6%） followed by depression （10.7%） and stress （7.9%）. Depression, anxiety and stress between seven hospitals were not significantly different （P〉0.05）. Male medical officers significantly experienced more anxiety symptoms than female medical officers （P=0.0022）, however depression and stress symptoms between male and female medical officers were not signi？ cantly different （P〉0.05）. Depression, anxiety and stress were not associated with age, working experience, ethnicity, marital status, number of shifts and type of system adopted in different hospitals （P〉0.05）. CONCLUSION： The prevalence of anxiety was high, whereas for depression and stress were considerably low. Gender was the only factor significantly associated with anxiety. Other factors were not associated with depression, anxiety and stress. Future research should aim to gain better understanding on unique factors that affect female and male medical officers’ anxiety level in emergency setting, thus guide authorities to chart strategic plans to remedy this condition.

Mirabilis jalapa (chandrakantha) leaves were used as a biosorbent for the removal of toxic metals ions cadmium (II), chromium (VI) and lead (II) from water. The physiochemical properties of the developed biosorbent were studied using FTIR. The efficiency of this developed biosorbent was tested using batch experiments under controlled conditions such as a function of pH, contact time, initial metal concentration and the optimization amount of biosorbent. The residual metallic ion concentrations of cadmium (II), chromium (VI) and lead (II) were determined using AAS. The biosorption capacity of Mirabilis jalapa was found to be pH dependant and the percentage removal of cadmium (II), chromium (VI) and lead (II) was increased with increasing adsorbate solution pH and a maximum value was reached at an equilibrium pH = 6 for cadmium (II), pH = 5.5 for chromium (VI) and pH 4.5 for lead (II) respectively. The equilibrium time required for the saturation loading of cadmium (II), chromium (VI) and lead (II) in the biosorbent was found to be about 120 min. The obtained equilibrium biosorption data was fitted to the linear forms of Freundlich isotherms. The results proved the efficiency of Mirabilis jalapa leaves powder as biosorbent for the removal of metal ions and it can be used for the development of an efficient, clean and novel technology for waste water treatment.

目的探讨解脲支原体、沙眼衣原体、精液白细胞与精子形态的关系。方法对1023例男性不育患者精液样本进行检测,解脲支原体采用培养法,沙眼衣原体采用生化酶法进行检测,白细胞采用联苯胺染色方法进行检测,精子形态检测采用计算机辅助系统下人工修正的方法进行分析。结果 UU阳性率为27.57%,CT 阳性率为30.11%。UU阳性组、CT阳性组及UU+CT阳性组正常形态精子百分率均显著低于对照组(P<0.01),亦均显著低于阴性组(P<0.05,P<0.01)。UU阳性组、CT阳性组及UU+CT阳性组白细胞异常率均显著高于对照组(P<0.001),亦均显著高于阴性组(P<0.001)。白细胞异常组正常形态精子百分率显著低于对照组和白细胞正常组(P<0.001)。结论UU、CT感染、白细胞、精子形态关系密切,UU、CT感染可能直接影响精子形态,亦可能通过激发白细胞异常,通过白细胞机制影响精子形态。
