Objective To assess the safety and effectiveness of neonatal disease screening so as to provide basis for the establishment of a mechanism for managing neonatal disease screening. Methods Using the ideas of evidence-based medicine, a safety and effectiveness assessment of neonatal disease screening was made by means of literature induction. Results The techniques used in neonatal disease screening were highly safe, but their effectiveness was affected by a variety of links and factors. The differences reported in literature in such aspects as blood-collecting time, testing methods, cut-off values, and indexes for outcome evaluation might mean negative impact on the effectiveness. Conclusion More attention ought to be attached to the understanding and assessment of the safety of screening techniques and more efforts need to be made in conducting systematic studies into the effectiveness of screening techniques.

Objective To elucidate the ESI-MS performance of lipophilic tanshinones and to establish a fingerprint of lipophilic tanshinones of Radix Salviae Miltiorrhiza.Methods The lipophilic tanshinones were extracted by ultrasonic wave with 95% ethanol from Radix Salviae Miltiorrhiza and the extracts were analyzed directly in positive ion mode by electrospray ion trap mass spectrometry(ESI-MS).Results The lipophilic tanshinones were easily to form molecular ions ~+ and dimeric sodium adduct ions ~+ in positive ion mode,molecular ions of lipophilic tanshinones were fragmentated through lossing H_2O,CO and A-ring cleavages in ESI-MS~2.The ESI-MS fingerprints of lipophilic tanshinone extracts with 14 selected characteristic peaks analyzed with SPSS software were characteristic and stable.Conclusion Lipophilic tanshinones have similar ESI-MS performance;the ESI-MS fingerprint is a useful tool for a rapid and special identification of lipophilic tanshinones in selected traditional Chinese medicine.

Bile reflux gastritis is a common and frequently occurring disease of the digestive system,and the pathology is diverse.Professor Zhou Xinyou emphasized that the disease primarily affects the gallbladder,liver and stomach,advocating for a comprehensive differentiation of its etiology and pathogenesis across three distinct stages.In the early stage,the gallbladder is dysfunctional,which then affects the stomach;In the intermediate stage,there is congestion in the liver and gallbladder,leading to excessive wood element suppressing the earth element;in the late stage,gastric collaterals damage,with qi deficiency and blood stasis.Professor Zhou Xinyou follows the diagnosis and treatment ideas of"multiple compound methods,comprehensive application,and overall adjustment".For typical clinical symptoms,he has formulated the treatment principles and treatment methods of pain separation,general use,oral bitterness and upset,purging heat and stomach,treating gallbladder and stomach,regulating qi and resolving depression,so as to achieve both symptoms and root causes of treatment,gallbladder and stomach regulation.
