Objective To trace changes in the transcript level of the Treponema pallidum(Tp)protein Tp0751 in skin lesions of a rabbit model of early syphilis. Methods Three New Zealand white rabbits were intracutaneously injected with 0.1 ml of Tp (Nichols Seattle strains)suspensions (107 treponemes/ml)at 10 sites on the shaved back to establish a model of early syphilis. All the rabbits received a single injection with the total amount of treponemes being 107. Then, skin changes at injection sites were observed, and the size of skin rashes was recorded on a daily basis. Skin specimens sized 0.4 cm × 0.4 cm were excised from an injection site and a non-injection site(negative control)separately every 3 days for the detection of Tp0751 and Tp0574 mRNAs. The whole experiment lasted 30 days, and a total of 11 skin biopsies were carried out. Fluorescence-based quantitative PCR was performed to measure the mRNA expressions of Tp0751 and Tp0574 continuously and dynamically during the development of chancre. Results After intracutaneous injection of Tp suspensions, red papules occurred on the back of rabbits on day 6, and reached maximum size on day 19 with the formation of ulcer and chancre. On day 25, disseminated secondary syphilides gradually appeared all over the body surface of the rabbits. The mRNA expression levels of Tp0574 and Tp0751 increased at the early stage, peaked onday 15 (compared with the other time points, all P < 0.05), thereafter rapidly declined, but rose slightly on day 27. The standardized expression level of Tp0751 mRNA increased gradually after day 15, and peaked on day 24 (compared with the other time points, all P < 0.05). Conclusion The transcript level of Tp0751 was high in rabbits at the late stage of Tp clearance when generalized disseminated secondary syphilides had not appeared, suggesting that Tp0751 may be involved in the systemic spread of Tp.

Objective:To analyze the prescriptions for the treatment for epigastric pain in A Hundred Years of Traditional Chinese Medicine Clinicians in China. Methods:The clinical medical records of well-known TCM doctors for the treatment of epigastric pain were included in the A Hundred Years of Traditional Chinese Medicine Clinicians in China. The database of clinical prescriptions and medicines was built, and the ancient and the Ancient and Modern Medical Records Cloud Platform (V 2.1) was applied and the evaluation of drug efficacy, sex, taste, and menstruation were conducted. Descriptive analysis, association rules, hierarchical clustering, and complex network analysis were applied in the rule of medication, drug pairs and core prescriptions. Results:Data was cleaned according to the inclusion and exclusion criteria, and 270 prescriptions were collected, involving 265 kinds of drugs, and the cumulative frequency of drug use was 3 249. The analysis showed that the drugs commonly used by famous traditional Chinese medicine doctors for the treatment of epigastric pain were mainly warm drugs, tast-balance drugs, and mildly cold drugs. The main flavors of medicines were pungent medicines, bitter medicines, sweet medicines, and effects were mainly drugs that regulate qi, clear heat, and invigorate the spleen. The frequency of drug meridians mainly belonged to spleen meridian, stomach meridian, lung meridian, liver meridian, heart meridian. The effects of the drug were mainly to dry dampness, reduce side effects, regulate qi, clear heat, invigorate spleen, and soften liver and analgesics. Association rule analysis found that the commonly used drug pairs were Pinellia- Tangerine Peel, Atractylodes Macrocephala- Poria, Poria- Tangerine Peel, Atractylodes- Tangerine Peel, Amomum tangerine Peel, Ochre- generation- Inula, Rhizoma Coptis- Evodia, and so on. Cluster analysis showed that Liujunzi Decoction, Zuojin Pill, and Shaoyao Gancao Decoction were mainly used. The drug complex network diagram showed that the core prescription of the drug is Xiangsha Liujunzi Decoction. Conclusion:The well-known TCM doctor focuses on strengthening the spleen and regulating qi, reconciling qi and blood, The treatment identified that the mutual warming and clearing, tonifying and deoppilation, and neutral are the main principles.

Intestinal flora imbalance and abnormal glucose and lipid metabolism are important risk factors and pathological mechanisms of colorectal polyps. "Spleen deficiency and dampness accumulation" is the core pathogenesis of colorectal polyps. The imbalance of intestinal flora is related to spleen deficiency, and the application of Chinese herbs for invigorating spleen is helpful to the recovery of intestinal flora balance. Abnormal glucose and lipid metabolism is related to dampness accumulation, and it is effective to treat it with bitter and spicy herbs or spleen-invigorating and dampness-eliminating herbs. The interaction between intestinal flora imbalance and abnormal glucose and lipid metabolism changes intestinal microenvironment, damages intestinal epithelial cells, causes abnormal proliferation of intestinal stem cells and leads to colorectal polyps, which is consistent with the pathogenesis of spleen deficiency and dampness accumulation in Traditional Chinese Medicine. Thus, we tried to explore the biological connotation of the pathogenesis of "spleen deficiency and dampness accumulation" of colorectal polyps from the perspective of the interaction of intestinal flora and glucose and lipid metabolism, in order to provide reference for identifying high-risk population and analyzing the therapeutic mechanism of compound prescription for invigorating spleen and removing dampness.

Objective To establish and implement an appointment interview policy between head nurse and nurses in ICU,in order to reduce their job burnout and to improve the job satisfaction and nursing quality. Methods A total of 68 appointment interviews were performed between head nurse and 28 nurses in ICU from February 2014 to September 2015.The job burnout level,job satisfaction,and the nursing quality were compared before and after the intervention.Results After the intervention,the score of emotional exhaustion reduced from (29.17 ±7.90)to (23.08 ±6.58);the personal achievement increased from (31.63 ±5.20)to (36.13 ±5.90);the job satisfaction significantly improved from (58.96 ±7.17)to (64.38 ±4.92);the nursing quality also improved from (80.13 ±1.65)to (88.88 ±1.89).The differences of the above scores had statistical significance (P <0.05 ).Conclusions The establishment of the appointment interview policy can effectively improve the relationship between the head nurse and nurses and provide supports to reduce their job burnout and improve the job satisfaction and nursing quality.

Platelet is the key factor in hemostasis and coagulation,its potential in inflammatory response and immune response has been widely concerned in recent years.A growing number of studies indicate that tissue damage in inflammatory bowel disease is not only the result of dysregulated immune response,but also the active participation of various other cellular systems,and platelet might play an important role in intestinal mucosal inflammation and immunity.This article reviewed the abnormal changes and possible mechanisms of platelet in inflammatory bowel disease,and the prospects of platelet as a specific treatment target for inflammatory bowel disease.

OBJECTIVETo evaluate the prevalence of primary gout in the Shantou area, China, and to understand its clinical features.
METHODSSamples from three surveys of the Chenghai across ten years were studied. Clinical, laboratory and radiology data of 419 cases of primary gout were collected and analyzed.
RESULTSPrevalence of primary gout in the three surveys were 0.17%, 0.15% and 0.26%, respectively. Among the clinical patients, the ratio of male to female was 21:1; the average age of onset of women was significantly higher than that of men. The number of cases in the last ten years has been increasing. In the first wave of cases, the first metatarsophalangeal joint was involved in 82.1% of all cases; no fourth metatarsophalangeal joint involvement had been observed. Hyperlipemia was the most common accompanying abnormal laboratory test (57.1%). Radiographic bone erosion was found in 49.4% patients, most of them with disease duration more than 5 years.
CONCLUSIONSThe prevalence of primary gout in Shantou area has been increasing in the last ten years. Changes in diet and lifestyle may be responsible for this rapid increase.
