1.ISOLATION, IDENTIFICATION OF LAS-DEGRADING FUNGI AND THEIR BIODEGRADATIVE CHARACTERS
Microbiology 1992;0(03):-
From the LAS-polluted soil were isolated 12 strains of LAS-degrading fungi. They belong to Penicillium, Aspergillus, Scopulariopsis and Cephalosporium. Conditions for the induced formation of LAS-degrading enzymes and their characters of degradative reaction were studied. The LAS-degraded products by fungi and bacteria were analysed and compared.
2.Role of Aquaporins in Modulating Diarrhea-predominant Irritable Bowel Syndrome
Chinese Journal of Gastroenterology 2016;21(6):380-382
Aquaporins,known as a family of water channel proteins,are crucial factors involved in colonic transmembrane water transport and play important roles in maintaining the homeostasis of internal and external environment of intestinal cells and modulating enteric nerve functions. Diarrhea-predominant irritable bowel syndrome( IBS-D)is a commonly seen gastrointestinal functional disorder in clinical practice. Recently,there are more and more researches focusing on the roles of aquaporins in IBS-D,however,mechanisms of its protective or damaging effects on IBS-D are still not clear. In this review article,the progress of research on the modulatory effect of aquaporins in IBS-D was summarized.
3.Establishment of normative value of multiple segments motor nerve conduction velocity of bilateral median nerve and ulnar nerve
Chinese Journal of Rehabilitation Medicine 2009;24(11):1006-1008
Objective: To establish normative value of multiple segments motor nerve conduction of bilateral median nerve and ulnar nerve, including motor nerve conduction velocity (MCV)、latency (LAT)and amplitude (AMP). Method: Two hundred normal volunteers were divided into 5 groups according to different ages. Median nerve was examined at multiple points: palm, wrist, elbow, axilla and Erb's. Ulnar nerve was examined at multiple points: wrist, below elbow, above elbow, axilla and Erb's. The values of segmental MCV, LAT and AMP were recorded. Result: Gender and sidedness had no effect on MCV, LAT and AMP of median nerve and ulnar nerve. However, age had significant effects on MCV, LAT and AMP of median nerve and AMP of ulnar nerve. Conclusion: The examination of multiple segments motor nerve conduction of bilateral median nerve and ulnar nerve possess important value in diagnosis.
4.Zika Virus and Zika Viral Disease.
Chinese Journal of Virology 2016;32(1):121-127
Since Zika virus (ZIKV) has firstly been isolated in 1947, Uganda, outbreaks of Zika fever have been reported in many areas such as in Africa, Southeast Asia and America. Imported cases in China also have been reported. Zika virus belongs to the family Flaviviridae, genus Flavivirus, and include Africa subtype and Asia subtype. It is a mosquito-borne virus primarily transmitted by Aedes aegypti mosquitoes. Sexual transmission, Blood transmission and mother-to-fetus transmission were also reported. Zika virus can go though blood-brain barrier and infect central nervous system. Symptoms are generally mild and self-limited, but recent evidence suggests a possible association between maternal Zika virus infection and adverse fetal outcomes, such as congenital microcephaly, as well as a possible association with Guillain-Barré syndrome. Laboratorial Diagnosis includes nucleic acid detection, Serological test, and isolation of virus. Currently, no vaccine or medication exists to prevent or treat Zika virus infection. Preventive measures against Zika virus infection should be taken through prevention of mosquito bites and surveillance in epidemic area.

5.The standardization process of glycosylated hemoglobin tests
Chinese Journal of Laboratory Medicine 2012;35(6):511-516
Glycohemoglobin (HbA1c) is an important indicator for assessing long-term glycemic levels and diabetic complications of blood vessels in diabetic patients.However the test methods,reagents and technological capabilities in different laboratories are various,so there are significantly differences of the results in bias.In 2010 HbA1c was included in new guidelines from ADA for diagnosing diabetes,and recommended by WHO in 2011,which promoted the standardization process of HbA1c tests.In this article we analysed and reviewed main detection methods,the international advancement of standardization,current status of the establishment of HbA1c Reference system in China and its clinical application.
6.Correlation between traditional Chinese medicine syndromes and omics: a literature review.
Journal of Integrative Medicine 2011;9(12):1286-91
As the post-genome era is approaching, omics has become a hot topic in the research field of life sciences and is also widely used in traditional Chinese medicine (TCM) research. For discussing the correlation between syndromes and omics, the authors explored the application of genomics, proteomics and metabonomics in the study of syndrome classification from the macroscopic view, after a systematic and normative study of the literature. The authors drew the conclusion that research into the correlation between syndromes and omics has great clinical significance in terms of the scientific application and quantification of TCM treatment based on syndrome differentiation.
7.Development and Evaluation of a High Sensitive Atomic Fluorescence Spectrometric System
Chinese Journal of Analytical Chemistry 2015;(2):310-311
A high sensitive hydride generation ( HG) atomic fluorescence spectrometric system was developed using high current microsecond pulsed hollow cathode lamp ( HCMP-HCL) as the excitation source and its performance was evaluated. Test results confirmed that the excitation source could give out intensive atomic spectral lines. System precision (RSD, n=7) was 1. 1% for arsenic and 1. 4% for selenium. Detection limits (DLs, 3) were 0. 0066 μg/L and 0. 0075 μg/L, respectively. The developed AFS system was proved to have high reliability, low detection limit and remarkable improvement of analysis capability compared with that of commercial AFS instruments.
8.Several hot topics of clinical biochemistry
Chinese Journal of Laboratory Medicine 2014;37(1):9-12
With the rapid development of life science and relevant technology of clinical laboratory medicine,it raised higher demands for current clinical biochemistry,which is to maximize the clinical efficacy and application value under the perfect quality management system.Based on the evidence-based medicine,considering the national conditions and the new situation of medical reform,comprehensive assessment the clinical performance of new technologies and new tests,to provide more objective and reliable evidence for practical application and to guide clinical decision making,is of great significance for the rational allocation and utilization of the limited medical resources.At the same time,promoting the development of personalized medicine process gradually,trying to change the passive medical model,focusing on the disease prediction,prevention and control,taking people as the foremost,optimizing the treatment plan,and strengthening the safety and efficacy of drugs,will become hot topics of clinical biochemistry.

10.Accuracy of magnifying endoscopy with narrow-band imaging for detecting early esophageal cancer invasion depth:a meta-analysis
China Journal of Endoscopy 2016;22(9):1-5
Objective To evaluate the accuracy of magnifying endoscopy with narrow-band imaging (ME-NBI) for detecting early esophageal cancer invasion depth. Methods We searched Embase, Pubmed, Web of Science, Cochrane Library, CBM, CNKI, Wanfang and VIP databases from inception to Feb.2016. Domestic articles related to the accuracy of ME-NBI detecting the early esophageal cancer invasion depth were collected comprehensively. The quality of the papers was evaluated by quality assessment of diagnostic accuracy studies (QUADAS). Data analysis was conducted by Stata 12.0 software. Results Seven group data from six studies including 319 patients with 366 lesions met the inclusion criteria. The pooled sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, SROC area under the curve and DOR were 93.8 % (95 % CI: 0.886~0.967), 75.2 % (95 % CI: 0.658~0.827), 3.779 (95 % CI: 2.685 ~ 5.318), 0.083 (95 % CI: 0.044~0.155), 0.80 (95 % CI: 0.770~0.840) and 45.658 (95 % CI:21.006~99.240). Conclusions The results suggest that ME-NBI may be an effective tool for detecting invasion depth of early esophageal cancer, which plays an important role in clinical selection of surgical approach and treatment.
