Objective To explore a new method of nasal tip plasty and its clinical effect,which is much accorded with biomechanical properties of the human body.Methods From June 2010 to March 2016,a total of 33 cases of nasal tip surgery,6 males and 27 females,were performed.Ages ranged from 22 to 46 years in this group.Ear cartilage was trimmed into two strips and sutured them together in a M shape.When located to the original position of the nasal alar cartilage,theM shaped cartilage could be used in nasal tip;when fixing part of it on the nasal septum or lengthened nasal septal cartilage,the M shaped cartilage could be used in cosmetic surgery of nasal tip lengthening.Results The follow-up period was from one month to 60 months,with average 14 months.29 patients (87.9 ％) were satisfied with the efficacy and 2 patients were suffered from infection (6.1 ％).Conclusions When the M-shaped cartilage is fixed with lengthened nasal septum,it can lengthen the nasal tip much more and the contouring and texture of nasal tip are better than that of using a shield or a cap cartilage graft.

OBJECTIVETo detect the expression and distribution of interleukin-17 and interleukin 17 receptor (IL-17R) in nasal polyps and to probe into their significance in the pathology of nasal polyps.

METHODSThe methods of immunohistochemical staining and western blot were used to detect IL-17 and IL-17R in nasal polyps and controls.

RESULTSIn nasal polyp tissues, IL-17 expressed mainly in cytoplasm of plasm cell, less in prickle-cell layer of the epithelium and the acinus of the serous gland. In turbinates, IL-17 also expressed in the cytoplasm of the plasm cell, the prickle-cell layer of the epithelium and the acinus of the serous gland. The expression of IL-17 between nasal polyps and turbinates differed significantly (t = 2.237, 2.176, 2.246, P < 0.05, respectively). Both IL-17 and IL-17R displayed specific bands in nasal polyps and turbinates, but the bands of IL-17 and IL-17R in nasal polyps were stronger than those in turbinates.

CONCLUSIONSIL-17 may have an important role in the occurrence of nasal polyps by specific combination with IL-17R and over-expression in nasal polyps.

Objective To find out the situation of Kashin-Beck disease and it's dynamic changes in Yan'an city, and provide basis for decision-making on prevention and control of the disease. Methods In accordance with the national monitoring program on Kaschin-Beck disease, 21 villages were selected from 6counties in Yan'an, clinical and X-ray inspection of 7 to 13 year-old children were made according to historical illness information from 2006 to 2008. Clinical monitoring on Kashin-Beck disease was made in 2008 for people over 16 years old from 5 villages in 5 counties. Results One thousand and one hundred eighty children were found positive with the illness from 2006 to 2008, with 7 cases of grade Ⅰ , the detection rate was 0.59%(7/1180).One thousand and one hundred sixty-two people were taken X-ray photo on right hand, with no positive case found.In 2008, 1444 adults were taken clinical examination, the detection of grade Ⅰ and over were 160 cases, the detection rate was 11.08%(160/1444), mainly in the age of 36 years[93.75%(150/160)]. Conclusion KashinBeck disease in Yan'an city is in stable condition, but surveillance and preventing measures are stilled needed.

Objectives To study the level and development of serum specific antibody against severe acute respiratory syndrome coronavirus(SARS-CoV)of different populations in SARS pestilence district after SARS outbreak in a general hospital.Discuss SARS sub-clinical infection and protective action of the IgG antibody.Methods Seroepidemiology method,enzyme-linked immunosorbent assay (ELISA)and indirect immunfluorescence assay(IFA)were employed to investigate the changing level of serum antibody to SARS-associated coronavirus in non-SARS population in SARS pestilence district during and after SARS outbreak.The development of IgM and IgG antibody in patients with SARS in 6 weeks after the onset of SARS was studied qualitatively.The level changing of IgG antibody in con- valescent patients with SARS in 82 weeks after the onset was observed dynamically.Results The ELISA test outcome of IgG antibody was negative in 200 non-SARS people who were random samples of normal mass in SARS pestilence district and common community.The positive rate was 0.41% in 487 SARS high risk population tested by ELISA,but showed negative when retested by IFA.The A value level of IgG antibody existed significant difference in non SARS mass during and after SARS outbreak and the later's was higher them the former's(P

Objective To evaluate the effectiveness of suberselective uterine arterial embolization for uterine fibroids.Methods Uterine arterial embolization with golyvimylalcohol(PVA) particles or Iodized oil and Gelfoam or Pingyangmycin lipiodol and Gelfoam was performed in 182 patients with uterine fibroids.Results Bilateral and unilateral superselective uterine arterial embolization were performed in 173 cases and 9 cases respectively. 6～28 months (mean 11 months) after the procedure, complete disappearance of tumor(16 cases), an average shinkage of 67% in tumor volume(152 cases) and a mean 42% reduction of uterine volume were obtained in 168 followed-up cases. The clinical symptoms were relieved significantly.The main side effets were hypogastic pain(135/182).Conclusion Superselection uterine arterial embolization is an effective and microinvasive method in treating uterine fibroids.

OBJECTIVETo study the diagnosis and treatment of pheochromocytoma in urinary bladder.

METHODSSix cases of bladder pheochromocytoma were studied. Four cases showed hypertension, 3 of which were paroxysmal hypertension during urination. Catecholamine (CA) was increased in a case, and vanillymandelic acid (VMA) was increased in 2 cases. Bladder submucosal mass was detected by B-ultrasound in 5 cases (5/5), computerized tomography (CT) in 3 cases (3/3), cystoscopy in 5 cases (5/6). Four cases took alpha-receptor blocker for 2 weeks, 1 case took beta-receptor blocker to decrease heart rate. All patients were treated with surgical operation including 4 partial cystectomies, 2 excavations.

RESULTSThree cases had manifestations including headache, excessive perspiration and hypertension during cystoscopy. Four cases were confirmed before operation. Two cases showed hypertension during operation. All patients were pathologically diagnosed as pheochromocytoma postoperatively. In five cases followed up, blood pressure returned to normal. No patient had relapse and malignancy.

CONCLUSIONSTypical hypertension during urination comprised the main symptoms. We should highly suspect bladder pheochromocytoma if a submucosal mass was discovered with B-ultrasound, CT, (131)I-MIBG (methyliodobenzylguanidine) and cystoscopy. The determination of CA in urine is valuable for qualitative diagnosis. The preoperative management of controlling blood pressure and expansion of the blood volume are very important. Surgical operation is a good method for effective treatment. Postoperative long-time followed up is necessary.

Objective To find out the status of HIV infection,sexual behaviors with both men and women as well as condom use among currently married men who have sex with men (MSM) so as to document for HIV intervention targeting this sub-population,in Beijing,Chengdu,Harbin and Zhengzhou cities.Methods “Snowballing” sampling method was used to recruit subjects in four cities.Participants were investigated by anonymous questionnaire containing demographics,sexual orientation,both homosexual and heterosexual behaviors and condom use during the past 6 months.Blood samples from participants were used to test HIV antibodies.Results Of the 858 participants for four cities,the average age was 38.3 (SD=9.1) years.36.7％ of them had completed the junior high school or under.The percentage of participants who identified themselves as homosexual,bisexual,and heterosexual or undecided were 40.9％,54.3％ and 4.8％,respectively.The overall HIV prevalence was 8.0％,and among four cities the HIV prevalence in Chengdu was the highest ( 13.3％ ).Results from the Multiple logistic regression analysis showed that never used condoms when having anal sex with men during the past 6 months among participants who did not have a city residential card,identifying himself as having homosexual orientation,living in Harbin,having first anal sex experience before 18 years of age the range of OR value was 1.5-2.1.In addition,the faetors associated with never using condoms in vaginal sex with women during the past 6 months were as follows:being over 46 years old,not having a city residential card,living in Beijing,identifying himself as heterosexual orientated or with unknown sexual orientation,never using condoms in anal sex with men during the past 6 months,the range of OR value was 1.7-5.9.Conclusion The prevalence of HIV infection seemed to be quite high among those currently married MSM.High rates of unprotected homosexual and heterosexual behaviors might accelerate the spreading of HIV from currently married MSM to their wives.

Spleen kidney Yang deficiency (SKYD) diarrhea is a common syndrome in tranditional Chinese medicine (TCM). Until now, there is not an ideal SKYD diarrhea rat model for the research. In this study, we compared single factor way (method I, injecting hydrocortisone and gavaging Sennae Folium) with compound factors way(method II, gavaging adenine, improper diet, exhaustion, and gavaging Sennae Folium) on establishing SKYD diarrhea rat model. After modelling, diarrhea index, D-xylose excretory rate, NOS/cGMP signal transduction system, organ index and histopathology examination were used to evaluate the two ways. The results showed that, compared with health group, all the assessment criterias of method I and method II had significant differences (P < 0.01, 0.05). In addition, the index such as diarrhea index, NOS/cGMP signal transduction system, organ index (kidney, testis and thymus) and histopathology examination had significant differences (P < 0.01, 0.05) between method I and method II. In conclusion, the compound factors modelling method better conforms to the symptom of diarrhoea model caused by SKYD. This new modelling method provides a basis for studying on TCM astringents warming and tonifying the spleen and kidney, relieving diarrhea.

OBJECTIVETo study the expression of phosphatase and tensin homology deleted on chromosometen ten (PTEN) protein, a tumor suppressor gene in breast cancer and its correlation with p27(kip1) and cyclin D1 expression.

METHODSPTEN protein expression, p27(kip1) and cyclin D1 protein expression were detected by immunohistochemical method in paraffin sections from 61 women with primary breast cancer. PTEN protein expression was compared with clinico-pathologic parameters as related to p27(kip1) and cyclin D1.

RESULTSPTEN, being shown in the cytoplasm, was negative in 6.6% (4/61), reduced in 41.0% (25/61) and positive in 52.5% (32/61) samples. PTEN expression level was correlated with axillary lymph node status, loss of estrogen receptor stain, recurrence and metastasis. On univariate analysis, the disease-free survival rate of patients with higher PTEN expression (> 50% cells stained) was better than those with lower expression (P = 0.0101). However, there was no correlation between p27(kip1), cyclin D1 expression or PTEN expression.

CONCLUSIONPTEN, its lower expression being correlated with poor outcome of breast cancer patients, plays a prominent role in breast cancer. p27(kip1) or cyclin D1 may not be the primary downstream genes of PTEN in breast cancer.
