AIM:To establish a specific method for the identification of 26 chemical drugs added illegally into analgesic-antipyretic traditional Chinese medicines and health food. METHODS: The liquid chromatography-ion trap mass spectrometry method was used.Comparing with retention time and spectrums of references in library set up by ourselves,the target compounds in sample were screened and identified. RESULTS: Sixty samples were tested and Naproxen,Ibuprofen and Aspirin were detected out. CONCLUSION: The method is accurate,sensitive and easy to operate, which is first reported in China and so many compounds could be detected at the same time.

Quality control of traditional Chinese medicine (TCM) has become bottlenecks of TCM industry devel-opment and TCM international recognition. To solve the retational problems, we explored the establishment of new quality control method based on efficacy and safety. Firstly, material basis of TCM efficacy was investigated deeply and systematically. Then, quality control method based on efficacy was established by using active ingre-dients as markers. We also establish detection methods based on safety, such as pesticide residues, heavy metals and harmful elements , mycotoxins .

SUMMARY To summarize the experience of managing substernal goiter by totally endoscopic procedure and evaluate the curative effect , we analysed eight patients diagnosed as substernal goiter type Ⅰ and treated with totally endoscopic technique via central routing approach during March 2011 to June 2013 in Beijing Shijitan Hospital retrospectively .The feasibility , safety and curative effect of this surgical tech-nique were estimated .All the cases were successfully operated with the totally endoscopic procedure , and the pathological result showed that 6 were goiter and the other 2 were minimal papillary carcinoma .None of the patients suffered from any complication , and the median follow up time was 6 months ( 1 -28 months) .The totally endoscopic technique is a feasible , safe and cosmic one for managing substernal goiter type Ⅰ.

OBJECTIVE: To investigate and analyze the status of anxiety and depression among patients with four types of peripheral vertigo. METHOD: The clinical data of patients with one of the four types of peripheral vertigo, namely benign paroxysmal positional vertigo (BPPV), vestibular migraine (VM), Menière's disease (MD), and vestibular neuritis (VN), were collected. Thorough otological and neuro-otological examinations were performed on these patients, and their status of anxiety and depression were assessed using self-rating anxiety scale (SAS) and self-rating depression scale (SDS). RESULT: A total of 129 patients with one of the four types of peripheral vertigo(49 cases of BPPV, 37 cases of VM, 28 cases of MD and 15 cases of VN) were included in the study. The scores of SAS and SDS were higher in the patients with VM or MD than those with BPPV or VN (P < 0.05), and the incidence of anxiety (VM = 45.9% MD = 50.0%) and depression (VM = 27.0% MD = 28.6%) were higher in the patients with VM or MD than those with BPPV or VN (P < 0.05). Paired comparisons showed the differences between the incidences of BPPV and MV groups, BPPV and MD groups, and MD and VN groups were statistically significant (P < 0.05). CONCLUSION Among patients with different types of peripheral vertigo, anxiety/depression is more common in patients with VM or MD. This may be due to the different mechanisms involved in different types of vertigo, as well as differences in the prevention and self-control of the patients against the vertigo.

A thiosulfate-oxidizing bacterium TX was isolated from polysulfide wastewater treatment system.It was preliminarily identified as Halothiobacillus sp.according to its morphological,physiological proper-ties and similarity analysis of 16S rRNA gene sequence(GenBank accession No.EU871645).This bacte-rium was an obligate chemolithoautotrophic sulfur-oxidizing bacterium since it could utilize thiosulfate,elemental sulfur,tetrathionate,sulfide or sulfite as sole energy source but did not show growth on the me-dium with glucose,sucrose,fructose,lactose,mannose or yeast extract as sole carbon source.The optimal growth condition for thiosulfate oxidation was 30?C~35?C and pH 3.0~5.0 respectively.Significant reduc-tion in medium pH from 4.0 to 1.2 was observed due to oxidation of thiosulfate to sulfate during the batch culture incubation period.During the course of thiosulfate oxidation accumulation of tetrathionate was ob-served either in synthetic medium or in the mixed liquor from aeration tank of the polysulfide wastewater treatment system.This indicates that the "S4 intermediate(S4I)" pathway was responsible for thiosulfate oxidation in this bacterium.

Objective To explore the sonographic characteristics and to evaluate its diagnostic value of hepatic lymphoma (HL). Methods The clinical data and abdominal sonographic ifndings of 18 consecutive patients with histological proven diagnosis of lymphoma with liver involvement were reviewed, including contrast-enhanced ultrasound (CEUS) images. Results The liver sonographic features of 18 HL were differentiated as three types including nodular, diffuse and mixed type. Nodular type showed well-deifned hypoecho lesions in 6 cases with penetrating vascular lfow signals in 2 cases and no vascular lfow signals in 6 cases by color Doppler imaging. In 3 cases by CEUS, all the hepatic focal nodulars showed variable arterial enhancement but wash-out in the portal venous and late phases. For diffuse type cases, hepatomegaly without nodule was showed in 11 cases. Vasular in liver showed normal in 8 cases and abnormal in 3 cases. For mixed type cases, hepatomegaly and multiple ill-deifned hypoechoic lesions with normal vascular in liver were showed in 1 case. Hepatosplenomegaly and abdominal lymphoadenopathies were identiifed in 11 cases. Conclusions The characteristics and the types of sonographic ifndings may be helpful in differentiating HL from other liver lesions.

Objective To find out the iodine nutritional status of children in Xiamen island, and to provide the scientific basis for iodine supplimentation. Methods On March 2010, thyroids of all children aged 6to 12, from primary school on the Xiaodeng island of Xiamen were examined by palpation, urinary iodine, iodine content of salt athome and IQ level were tested, and were collected 20 households, iodine content of drinking water was tested randomly. Results IQ testing and thyroid palpation were carried out among a total of 156 children, the goiter rate of children was 1.28% (2/156), the mean IQ was 110; 154 urine samples were taken, the median urinary iodine was 219.1 μg/L; a total of 153 salt samples were tested, and the qualified rate of iodized salt was 87.58%(134/153), and the mean iodine content in the tap water was 4.52 μg/L Conclusions Iodine nutritional status of the island residents is better, and there are no such problems as excessive iodine.
