We present a rare case report of foreign body of the nasal apex in a 22-year man who were hospitalized because of a bit of metal rebounded. There was slight bleeding at wound site with a feeling of pain and swelling. On physical examination, the apex lied in the median position with a bleeding cut about 3 millimeter in length. There was no visible stump on the cut or rupture in the nasal vestibular. Computed tomographic scan showed the abnormal high-density shadow in the nasal apex while the foreign body was located in the subcutaneous tissue of the antero-upper part of septal cartilage. The admitting diagnosis was foreign body in nasal apex. Endoscopic surgery was adopted to remove the foreign body.

OBJECTIVE: To summarize the clinical characteristics and treatments of patients with malignant transformation of sinonasal inverted papilloma (SNIP), and to explore the factors influencing the prognosis of malignant SNIP. METHOD: To retrospectively analyze the clinical data of 35 patients with malignant SNIP. The prognosis affected by age, gender, pathogenetic locations, pathology, clinical stages and treatments were analysed using Kaplan Meier, Log rank and Cox method. RESULT: In our research, 5 years survival rate was 68.6% in malignant SNIP. There were 3 factors effecting the 5 years survival rate of malignant SNIP: clinical staging, histopathological features and treatments while gender, age, disease location, and percentage of the malignant cell in the entire tumor tissue had no effect on overall survival rate. Clinical staging and treatment were the independent factors that influenced the prognosis of malignant SNIP (P value was 0.019 and 0.006). CONCLUSION Risk factors that independently influence the survival of patients with malignant SNIP were the clinical staging and treatment. The degree of histo pathological features can be the secondary indicator to judge the prognosis of malignant SNIP. Endoscopic surgery or comprehensive therapy performed on patients properly is therapeutically effective.

[ABSTRACT]OBJECTIVETo investigate malignant transformation of sinonasal inverted papilloma(SNIP) treated by endoscopic or endoscope assisted surgery, in order to analyze its probable prognostic factors and the optimized method.METHODSThe clinical data of 27 cases with malignant transformation of SNIP treated by endoscopic or endoscope assisted surgery from September 2001 to September 2010 were reviewed. According to preoperative imaging examination and UICC staging criteria, 3 cases were T1, 8 cases were T2, 12 cases were T3 and 4 cases were T4. 16 of them received radiotherapy after endoscopic surgery while the other 11 received surgery alone. RESULTSAll cases were confirmed as squamous cell carcinoma pathologically after surgery. The 5-year overall survival rate was 77.8% for all the patients. The 5-year survival rate was 75.0% for surgery alone group, of which 5 cases recurred locally after operation. The 5-year survival rate was 81.8% for surgery combined with radiotherapy group, of which 5 cases recurred locally and 2 cases died from intracranial metastasis.CONCLUSIONEndoscopic or endoscope assisted surgery can be used in the management of malignant transformation of SNIP to improve the quality of life, with the preponderances of desired effect and less complication. Application of radiotherapy after surgery could improve long-term survival rate of the patients.

Background:Irritable bowel syndrome( IBS ) is one of the most common functional gastrointestinal disorders. Analyzing the regional differences of symptomatic profiles may provide guidance for the diagnosis and treatment of IBS. Aims:To preliminarily investigate the symptomatic characteristics of IBS patients in Fujian province,China for the reference of diagnosis and treatment of the disease. Methods:A total of 703 IBS out-patients based on the RomeⅢcriteria and presented to the gastroenterological clinic of 15 tertiary hospitals in Fujian Province,China from Jun. 2011 to Apr. 2012 were enrolled in a face-to-face survey. The questionnaire mainly included demographic data,course of the disease, and clinical symptoms. Results:In 703 IBS patients,the ratio of male to female was 1:1. 3,and the peak of age was 35-45 years(32. 4%). More than half of the patients were diarrhea-predominant IBS(IBS-D,58. 2%),while constipation-predominant IBS( IBS-C)accounted for 22. 6% of the patients. Abdominal pain/discomfort,abdominal distention and abnormal defecation,including diarrhea,constipation,feeling of incomplete defecation and mucous stool were the most important lower GI symptoms. In the four subtypes of IBS,the symptoms of mixed IBS( IBS-M)were most serious( P<0. 05). Compared with IBS-C,abdominal pain was more severe in IBS-D and IBS-M(P<0. 05),however,abdominal distention was more severe in IBS-C than in IBS-D(P<0. 05). About one third of the patients(32. 9%)were overlapped with upper GI symptoms,and the most common upper GI symptoms were postprandial fullness and eructation. Sixty-eight (9. 7%)patients were overlapped with functional dyspepsia. Conclusions:In Fujian Province,China,more than half of the IBS patients were IBS-D. The symptomatic profiles are different between different subtypes of IBS. Some of the IBS patients may be overlapped with upper GI symptoms or functional dyspepsia.

Objective To analyze the prognostic factors in patients with cervical squamous cell carcinoma of stage Ⅰb and Ⅱa treated by surgery,and to investigate their guid roles in available post-operation adjuvant therapy. Methods The clinicopathologic records of 306 patients with cervical squamous cell carcinoma of stage Ⅰb and Ⅱa who underwent radical hysterectomy and pelvic lymphadenectomy were retrospectively analyzed, and the prognostic factors were explored by univariate and multivariate methods. Independent prognostic factors were identified by COX proportional hazards regression model. Results The overall 5-year survival rate of these 306 patients was 78.1%. In univariate survival analysis, the poor prognostic factors included poor differentiation, positive pelvic lymph nodes, deep stromal invasion, parametrial extension, tumor size≥4 cm, and lymph vascular space involvement (P

This study was aimed to observe effect of pomegranate leaf tannin and ellagic acid on primary rat adipocyte differentiation and lipid metabolism-related factor expression. Primary rat preadipocyte was in vitro cultured to observe the effect of pomegranate leaf tannin and ellagic acid on lipid fat cells as well as mRNA expression of its related factor. The results showed that pomegranate leaf tannin and ellagic acid had obvious inhibition effect on fat formation in fat cells. It had certain inhibition effect on activities of lipoprotein lipase (LPL) and glucose-3-phosphate dehydrogenase (GPDH). It promoted fat decomposition and reduced intracellular lipid content. It upregulated PPARγ and fatty acid-binding protein (aP2). It downregulated obese (ob) gene level. It was concluded that pomegranate leaf tannin can inhibit fat generation of fat cells and promote fat metabolism. Ellagic acid was its main active ingredient, which had the same effect as pomegranate leaf tannin.

Objective To study the correlation between the coagulation factor Ⅶ (F Ⅶ) and progressive hemorrhage after brain contusion in mice and provide the experimental evidence for the clinical application of recombinant human FⅦa.Methods Twelve male BALB/c mice were given liposomeencapsulated FⅦsiRNA via tail vein at doses of 1,3,5 and 10 mg/kg with 3 mice per dosage.The other 3 mice received equivalent volume of normal saline as controls.Two days after the injection,mice blood sampling was used to detect FⅦ mRNA expression in liver using real-time PCR,level of plasma FⅦ using ELISA method,and activity of plasma FⅦ using chromogenic substrate assay.The optimal dose at which F Ⅶ expression was inhibited was determined.Thirty BALB/c male mice were assigned to two groups (n =15 per group) according to the random number table:FⅦ-suppressing group,mice were injected with FⅦsiRNA at the optimal dose and control group,mice were injected with same volume of negative control vector.The model of brain contusion was established in both groups.Volume of hemorrhage following brain contusion was measured at 3,24 and 72 h postinjury,and hematoma volume at 24 and 48 h postinjury.Results Liposome-encapsulated siRNA delivery down-regulated FⅦ expression in the mouse liver.Level and activity of plasma FⅦ were also reduced significantly.The optimal siRNA dose was 3 mg/kg.At 3,24 and 72 h postinjury,relative volume of brain hemorrhage in FⅦ-suppressing group was 1.46 ± 0.10,1.82 ± 0.23 and 2.28 ± 0.15 respectively,significantly higher than that in control group (1.00 ± 0.25,1.20 ± 0.31 and 1.20 ± 0.22 respectively) (P ＜ 0.05).At 24 and 48 h postinju-ry,volume of hematoma in FⅦ-suppressing group was (6.7 ± 1.5)mm3 and (9.8 ± 1.0) mm3,significantly higher than that in control group [(5.2 ± 1.2) mm3 and (5.5 ± 1.5) mm3] (P ＜0.01).Conclusions Level of FⅦ in vivo relates closely to the progressive hemorrhage of brain contusion in mice.Administration of FⅦ is effective to reduce the incidence of progressive hemorrhage.

Objective To explore the correlation between hyperlipidemia and colorectal polyps by compare the level of serum lipids in patients with colorectal polyps.Methods The levels of total cholesterol (TC),triglyceride (TG) and low density lipoprotein-cholesterol (LDL-C) of 159 patients with colorectal polyps and 138 controls were tested.The serum lipids between colorectal polyps group and control group,of colorectal polyps with different pathological type,of adenomatous polyps with different pathological type,of adenomatous polyps with different location,colorectal polyps of different gender were compared.Chi square test or t test were performed for data analysis.Results The incidence of hyperlipidemia of colorectal polyps group was 41.5％ (66/159),which was higher than that of control group (16.7％,23/138) and the difference was statistically significant (x2 =36.56,P＜0.01),its levels of TG,TC and LDL-C were all higher than those of the latter ((1.52±0.56) mmol/L vs (1.06 ± 0.42) mmol/L,(5.22±0.86) mmol/L vs (4.52±0.96) mmol/L,(2.85±0.66) mmol/L vs (2.52± 0.35) mmol/L; t=4.23,4.02,3.72,all P＜0.01).There were no significant differences in the levels of TC,TG and LDL-C between colorectal polyps with different pathological type (all P＞ 0.05).The incidence of hyperlipidemia of tubular villous adenoma and villous adenoma (progressive adenomas) was 60.0％ (15/25),which was higher than that of tubular adenoma group (33.3％,20/60) and the difference was statistically significant (x2=5.18,P＜0.05).The incidence of hyperlipidemia of left colon and rectal polyps group was 46.2％ (49/106),which was higher than that of right colon polyps group (28.6 ％,12/42) and the difference was statistically significant (x2 =3.87,P＜0.05).The incidence of hyperlipidemia of male colorectal polyps group was 47.2％ (51/108),which was higher than that of female group (29.4％,15/51) and the difference was statistically significant (x2 =4.53,P＜0.05).The level of TG of male colorectal polyps group was higher than that of female group ((1.84 ± 0.73) mmol/L vs (1.55±0.65) mmol/L) and the difference was statistically significant (t=3.98,P＜0.05).Age (r=0.766,P=0.009),TG level (r=0.535,P=0.012) and TClevel (r=0.688,P=0.025) were positively correlated with genesis of colorectal polyps.Conclusion There is a significant correlation between hypertriglyceride,hypercholesteremia and colorectal polyps.
