This study sets up an early-warning system framework of Chinese materia medica price, using price index as early warning indicator to establish black early-warning model, with indicator of price index volatility and limit line of "price principal". The research divides warning degree into 5 parts named negative heavy warning, negative light warning, no warning, positive light warning and positive heavy warning, with 5 corresponding lights to describe the change level of the medicine price. Then make an early-warning empirical research based on Chengdu Chinese materia medica price index from December in 2010 to October in 2013. ARMA model is applied to forecast index and the result of early-warning is analyzed, and finally farmer households, companies, customers and the government are recommended respectively.

Objective: To investigate the characteristics of clinical manifestations, diagnosis and treatment of NEBC (neuroendocrine breast cancer). Methods: This was a retrospective study. Ten consecutive female patients with NEBC were admitted in Department of Breast Surgery, Peking Union Medical College Hospital between January 2004 and December 2010. The average age of the ten patients was 52 years, and the follow-up period was 24-177 months (median 84 months). Results: Clinically, most of the NEBC manifested as breast lump, sometimes as NPBL (non-palpable breast lesion) or nipple discharge. An ultrasound examination usually revealed heterogeneous echoic mass with irregular shape and clear boundary. Mammography showed no significantly different changes from other kinds of breast cancer. Nine patients received curative resection for NEBC, among whom, seven underwent modified radical mastectomy, one underwent nipple and areola-sparing modified radical mastectomy, one with nipple discharge underwent excision of duct and relevant lobule and hook-wire-guided biopsy of breast lump, and later right mastectomy with sentinel lymph node biopsy. The expressions of hormone receptors like ER (estrogen receptor) /PR (progesterone receptor) were usually positive in NEBC, while the expression of HER2 (human epidermal growth factor receptor 2) was usually negative (-) to positive (+). At least one neuroendocrine marker like Syn (synapsin) or CgA (chromgranin A) was positive. During the follow-up period, metastasis was found in two patients and one of them had passed away. Conclusion: NEBC is a clinical entity different from breast cancer with BC-NE (breast cancer with neuroendocrine differentiation). NEBC may affect younger patients in China, ultrasound examination is valuable for diagnosis, and surgical and comprehensive therapy may achieve satisfactory outcome with relatively good prognosis, although there might be cases of metastasis.

Objective To investigate the epidemiology of 10 000 patients with mammary gland disease.Methods 10 000 mammary gland disease cages during 1987～2006 in Yangquan Tumor Institute were collected,all patients had integrity case files and were diagnosed by molybdenum target radiography,near infrared ray,sonography,aspiration-needle biopsy or polyrrhea smear examination.Results In 8919 outpatient treated cases,7493 suffered cyclomastopathy(84%).1081 cases were inpatient cared(11%),the top five mammary gland disease are:breast cancer 342 cases,cyclomastopathy 252 cases,adenofibroma 104 cases,intraductal papilloma 86 cases and ductal ectasia 76 cages.For breast cancer patients,there were 125 cases during 1987～1996,3 were 21～30 years old and 23 were 31～40 years old.The number during 1997～2006 was 217,24 were 21～30 years old and 69 were 31～40 years old.Conclusion In 10000 cases,there are 7745 cyclomastopathy patients(77.45%)which takes the first place.Especially for 342(3.42%)breast cancer cases,the incidence grew up and patients age was much younger.

The rabbit enteropathogenic E. coli (rEPEC) strain RDEC-1 possesses a lifA homologue adjacent to the LEE pathogenicity island. To study the entire nucleotide sequence and biological function of lifA,the DNA sequence and biological function of RDEC-1 lifA were analysed with gene cloning,gene knock-out and in vivo virulence examination. The result showed that the entire coding sequence of the lifA of RDEC-1 shares nearly absolute homology with the lifA of human isolates. RDEC-1 lifA inhibited IL-2 expression in stimulated rabbit peripheral blood mononuclear cells. We further demonstrated significant reduction in fecal bacterial shedding by RDEC-1 derivative lifA mutant when compared with its parent strain. In a competitive study when rabbits were inoculated with a combination of the WT and the mutant, the WT was the predominant bacteria recovered from fecal samples, while fewer mutant bacteria were recovered. However,the lifA mutant is able to induce A/E type of lesions as efficient as the parent strain. The data provide direct evidence that lifA of rEPEC plays a role in immunomodulation and in in vivo colonization in the intestinal tract.

Objective To investigate the alleviative effects of lidocaine postconditioning on pulmonary injury following ischemia reperfusion. Methods Seventy-two adult SD rats were randomized to 4 groups; sham group, ischemia-reperfusion (I-R) group, ischemic postconditioning(IPC) group and lidocaine postconditioning group. The pulmonary ischemia-reperfusion model was established by occlusion of the left hilum of lung for 45 min and the reperfusion was taken by removing the clamp for 2 h. At the moment of reperfusion, lidocaine 4 mg/kg was injected as a priming dose following a continuous rate of 4 mg/(kg · h). PaO_2, TNF-α, W/D of left lung, the level of MDA of left lung tissue were measured. At the end of reperfusion left lung was removed for microscopy. Results After reperfusion PaO_2 of lidocaine group was much higher than that of I-R group (P<0.05). Lidocaine postconditioning induced a significant decrease in the level of MDA of lung tissue[(7. 03±1.17) μmol/L] compared with ischemia reperfusion group [(8.77±1.42) μmol/L] (P<0.05). Lidocaine postconditioning resulted in a lower level of TNF-α [(1. 69±0.34) μg/L] than that of I-R group [(2. 52±0. 54) μg/L] (P < 0. 05). Microscopic examination showed that lidocaine postconditioning could decrease the level of edema of left lung and accumulation of neutro-phils. Conclusion Lidocaine postconditioning exerts a protective effect on pulmonary ischemia-reperfusion injury administered in the beginning of reperfusion. The effect may be explained by to the antioxidant effect and the suppression of expression of TNF-α.

Fibulin-1 is a widely distributed,versatile secretory calcium-binding glycoprotein which plays an important role on the formation of the structure of the extracellular matrix,the regulation of intercellular signaling and the inhibition of cell motility.Recent studies suggested a tumor-suppressive role for Fibulin-1.Here,this review focuses on the expression,function and mechanism of Fibulin-1 genes in tumor.

We reported a case of a work-related accident involving periorbital and intraorbital metal foreign bodies. The patient was a 43-year-old woman whose nasal dorsum was struck while she was sawing wood with nails. X-ray plain films of skull bone and computed tomographic scan of nasal sinus revealed two 5-mm-long metal objects lodged in right lacrimal sac and medial bulbar space of the right orbit. No deficits were noted in her visual acuities, visual fields, and ocular movements. Based on accurate positioning by imaging examination, transnasal endoscopic removal of metal foreign bodies was successfully accomplished. The patient recovered well without any complications after surgery.
