Objective To study the effects of MMP-9 (Matrix Metalloproteinase-9, MMP-9) in the pathogenesis of abdominal aortic aneurysms (AAAs) by localizing the expression of MMP-9 in the aneurysmal tissues. Methods By means of immunohistochemistry, the frozen sections (5 μm) with aneurysmal tissues (n = 10) were incubated with MMP-9 antibody-added agents, then the sections were stained and observed under the microscope to localize the expression of MMP-9, which displayed a brown precipitate within the arterial walls. The normal arterial wall tissues(n= 10)and the diseased arterial wall tissues from the arterial occlusive diseases (AODs) (n= 15) were also immunized exactly the same way as control. Results A quantity of positive granules which appeared within the aortic media showed the strong expression of MMP-9 in the AAAs, with the positive rate reaching 95%(19/20), while no expression of MMP-9 was observed in the normal artery. However, the scattered distributed positive granules were scen within the arterial wall of some cases of the AODs, implying the weak positive expression of MMP-9 in this disease with the positive rate of 26.7%(4/15). There was a significant difference of the expression of MMP-9 within the arterial wall between the AAAs and AODs(P＜0. 01). Conclusion High expression of MMP-9 within the aortic media faciliatates the degradation of collagen and elastin fibres and subsequent dilation of the aortic artery , thus playing an important role in the pathogenesis of AAAs. To refrain MMP-9 from enhanced expressing within the aortic wall is of clinical significance in the prevention and treatment of AAAs.

[ABSTRACT]OBJECTIVETo explore the efficacy and safety of localization for parathyroid glands with intravenous low dosage of methylene blue in thyroidectomy. METHODSWe retrospectively reviewed the clinical data of 41 patients who suffered from thyroid papillary carcinoma between Aug, 2014 and Jan, 2015 (9 males and 32 females, with a median age of 46 years). Thirty eight patients underwent primary thyroidectomy and 3 patients underwent second operation. A variety of thyroidectomy was performed in all patients, and who also underwent intravenous (3-4) mg/kg methylene blue in operation. RESULTSEighty four parathyroid glands were stained. Among 39 patients who's parathyroid glands were stained, the mean dyeing time was (31.27±9.41) min. Dyeing rates and dyeing time were not significantly different between 3 mg/kg group and 4 mg/kg group (t=0.24 and 0.20, all P>0.05). None of patients had the hypoparathyroidism problem such as peri-oral numbness, tingling, muscle aches and spasms. According to postoperative monitoring of parathyroid hormone, all of patients had no permanent hypofunction of the parathyroid gland. Neurotoxic effects and other serious side effects were not observed in all patients. CONCLUSIONIntravenous low-dose methylene blue in thyroidectomy is a safe, easy, and effective technique that facilitates rapid identification of parathyroid gland.

OBJECTIVE To observe the curative effect of Jieminqufeng decoction to the rats with allergic rhinitis. METHODS Fourty Wistar rats were randomly divided into 4 groups. There were Jieminqufeng decoction group (A),cetirizine group (B),model control group(C) and normal control group (D). The rats with allergic rhinitis were established with ovalbumin. The behavioral changes of the rats were observed. The histological and cellular morphological changes were studied with light microscope and transmission electron microscope. RESULTS The model control (C) group had typical symptoms of allergic rhinitis. By light microscope and transmission electron microscope,a lot of eosinophilic granulocytes were found in nasal mucosa. The mucosal cells were lost or destroyed. However,the histological and cellular morphological changes of nasal mucosa in Group A,B were similar to that in Group D. CONCLUSION The Jieminqufeng decoction is an effective drug to treatment of allergic rhinitis. It can decrease the aggregation and activation of eosinophilic granulocytes,lessen inflammatory reaction and block up the allergy.

Infant hair is a good medium to assess the cumulative exposure level of infant in the mother ' s body. Chlorinated persistent organic pollutants were ubiquitous and with the highest volume concentration in the human body. In this experiment, 20 infant hairs were collected from Beijing. The sample was overnight incubated in HCl, extracted with the mixture of hexane and dichloromethane, and cleaned up by a cartridge filled with alumina and acidified silica. The final eluate was concentrated, and 16 kinds of typical chlorinated persistent organic pollutants were detected with gas chromatography_high resolution mass spectrometry ( HRGC_MS). The results showed that the detection limit of the target compounds in sample was 1. 00-2. 50 μg/kg, the recovery of surrogate in all samples was more than 67 . 6%, and the range of recoveries for target compounds in spiked sample was 62. 5%-92. 3%. The positive rate is 100% for hexachlorobenzene,β_HCH and p, pˊ_DDE, 85% for γ_HCH, 50% for PCB28, and 40% for PCB52. The concentrations of Hexachlorobenzene, HCHs, DDTs and PCBs were 5. 48-8. 40 μg/kg, 3. 86-27. 1 μg/kg, 1. 16-18. 3 μg/kg and 2. 20-22. 1 μg/kg, respectively. The average concentrations were 7. 84 μg/kg for hexachlorobenzene, 6. 93 μg/kg for HCHs, 5. 53 μg/kg for DDTs, and 3. 44 μg/kg for PCBs. The method and the analysis results can be used to evaluate the accumulation level and cumulative exposure level of 16 target compounds for fetal in motherˊs body.

OBJECTIVETo improve early diagnosis rate and reduce the incidence rate of colorectal cancer, through the application of optimized sequential screening scheme for colorectal neoplasm in general population.

METHODSQuantitative risk assessment by questionnaires survey and fecal occult blood test (FOBT) were used to proceed preliminary screening among people aged 40 to 74. Electronic colonoscopy was applied to examine the whole colon and rectum among identified high-risk subjects. The detected cases received treatment for colorectal cancer, adenomatous polyps or non-adenomatous polyps. The early diagnosis rate and incidence rate of colorectal cancer were evaluated and compared with those before screening.

RESULTWith application of optimized sequential screening schemes, various types of colorectal lesions were detected in 1 117 subjects, including 69 cases of colorectal cancer, 701 cases of colorectal adenoma and 211 cases of advanced adenoma. The early diagnosis rate of colorectal cancer was increased by 58.19%, and its incidence rate also decreased significantly.

CONCLUSIONThe optimized sequential screening scheme is simple, economical, efficient in colorectal cancer screening of general population.

OBJECTIVETo compare the age-specific detection rates of colorectal neoplasms by colonoscopic screening among high-risk population in rural area and to provide evidence for determining the initial age in the colorectal cancer screening.

METHODSThe age-specific detection rates of colorectal cancers and adenomas, and the proportion of detected cases in each age group after screening by the optimized sequential colorectal cancer screening program in Jiashan County, Zhejiang Province, were analyzed.

RESULTSMass screening with the optimized sequential colorectal cancer screening program in Jiashan was conducted and 8867 colonoscopic examinations were performed. A total of 1811 individuals with at least one colorectal neoplastic lesion were found. Among them, there were 92 (1.04%) colorectal cancer patients, 1164 (13.13%) patients with at least one adenoma and 377 (4.25%) patients with at least one advanced adenoma. The detection rate of colorectal neoplastic lesions for the age group 40 - 44 was considerably lower than that in the age group 45 - 49. Hypothetically, to increase the initial age to 45-years for the optimized sequential colorectal cancer screening program would yield a 7.84% increase in the detection rate of total colorectal neoplastic lesions, 13.46% increase in the detection rate of colorectal cancer, 8.76% increase in the detection rate of adenoma, 12.24% increase in the detection rate of advanced adenoma and 19.64% lower in the cost of initial screening, 13.30% lower in the cost of colonoscopic screening.

CONCLUSIONSAmong the high-risk population aged 40 to 74, the detection rates of colorectal cancer and adenoma are increasing with the increase of age, the detection rates of colorectal cancer and adenoma as well as proportion of detected cases in the 40 - 44 age group are considerably lower. To increase the initial age to 45 for colorectal cancer screening in rural area of China is reasonable.
