BACKGROUND: Many studies focus on transforming growth factor β (TGF β) and its receptors, however, the distdbution of type Ⅰ TGF receptor (TGF-βR Ⅰ) in peripheral region of hypertrophic scars remain poorly understood. OBJECTIVE: To determine the expression and distribution of TGF-βR Ⅰ and type Ⅰ collagen in the peripheral and central areas of human skin hypertrophic scar. METHODS: A total of 30 cases with human cutaneous scars admitted at the Department of Plastic Surgery, First Affiliated Hospital and Department of Mammary Gland, Head and Neck Surgery, Tumor Hospital of Xinjiang Medical University from 1999 to 2002, were selected, including 20 cases with hypertrophic scar and 10 cases with normal scars. A total of 180 scars were obtained from central and peripheral areas of scars as well as normal skin tissues. The protein contents of TGF-βR1 and type Ⅰcollagen was detected by immunohistochemistry. In addition, the immunostaining positive in these samples was analyzed by semiquantitative analysis. RESULTS AND CONCLUSION: Compared to non hypertrophic scar and normal skin tissues, the TGF-βR1 expression of hypertrophic scar was obvious greater with strong positive reaction. The TGF-β R Ⅰ content was 100% in peripheral region of hypertrophic scar, which was notably 20% greater than that of central area (P < 0.05). The content of type Ⅰ collagen was both 100% in peripheral and central areas. The differences of positive TGF-β R Ⅰ and type Ⅰ collagen had no significance between peripheral and central areas of non hypertrophic scars (P > 0.05). There were few contents of TGF-βR Ⅰ and type Ⅰ collagen in normal skin tissues. The expression of TGF-β R Ⅰ is higher in peripheral than central areas of hypertrophic scar. Therefore, the peripheral area would be emphasized in the clinic work.

OBJECTIVE: To retrospectively analyze the long-term curative effects and prognostic factors of 137 cases of NPC patients treated with intensity modulated radiation therapy. METHOD: The three-dimensional conformal intensity modulated radiation therapy adopted for the design plan of 137 cases of newly diagnosed and no distant metastatic NPC patients. Evaluation of short-term clinical efficacy was made according to the efficacy evaluation criteria of WHO solid tumor one month after radiotherapy. During the 2 years after radiotherapy, re-examinations were made every 3 months. Two years later, re-examinations were made every 6 to 12 months, and the routine examinations included clinical body check, nasopharyngoscope, CT, B Chao, MRI, chest X-ray, bone scan, so as to understand the condition of cavum nasopharyngeum, cervical lymph nodes and cranial nerves. Life table method was adopted to calculate the overall survival rate, Kaplan-Meier method was used to calculate relapse-free survival rate, distant metasis-free survival rate and disease-free survival rate. Log-rank test was used for univariate analysis of 14 clinical factors which may exert influences on prognosis. Multivariate analysis was performed with the Cox regression model, P < 0.05 is of statistical significance. RESULT: (1) Of the 137 cases, the overall survival rates of 1-year, 3-year and 5-year were 98.5%, 90.3%, 74.6% respectively, relapse-free survival rates were 97.0%, 81.9%, 66.7% respectively; distant metasis-free survival rates were 96.3%, 80.5%, 56.0% respectively; disease free survival rates were 95.6%, 76.9%, 43.8% respectively. (2) Univariate analysis revealed that the influences of T-staging,N-staging, 92 Fuzhou clinical staging, combined chemotherapy, skull base bone destruction, injury of cranial nerve, retropharyngeal lymph node metastasis, residual disease, total time of IMRT on prognosis were of no statistical significance(with all the P values lower than 0.05) The influences of gender, nationality, age, pathological type and anemia or on prognosis were of no statistical significance(with all the P values higher than 0.05). (3) T-staging, skull base bone destruction, injury of cranial nerve, retropharyngeal lymph node metastasis, N-staging, combined chemotherapy, residual disease, total time of IMRT, and anemia were drawn into Cox model, and the results showed that N-staging, combined chemotherapy, injury of cranial nerve, residual disease, and total time of IMRT were independent factors that affect prognosis (with all P values lower than 0.05). CONCLUSION IMRT obviously has advantages than conventional radiotheraphy in treating NPC patients. N-staging, injury of cranial nerve, combined chemotherapy, residual disease, and total time of IMRT are the main factors that affect prognosis.

Objective To explore the psychological status of the patients with breast cancer and its influencing factors.Methods The psychological health status in 896 patients with breast cancer and 1 419 patients with benign breast diseases were surveyed and analyzed by adopting the Self-reporting Inventory(SCL-90).At the same time,SCL-90 was also used to analyze the differences of psychological health status among breast cancer patients with different occupations,degrees of education and family support attitudes.Results The each factor scores in breast cancer patients were higher than those in benign breast disease patients(P＜0.05).The scores of obsessive symptoms and somatization factor in breast cancer patients were higher than those of other factors(P＜0.05).In breast cancer patients,the proportion of workers and cadres with obsessive symptoms was higher than that of farmers.The family support attitude was good,and the proportion of obsessive symptoms was lower.The higher the education level,the lower the proportion of somatic symptoms.Conclusion Aiming at the existence of mental problems of higher somatization and obsessive symptoms,conducting the psychological counseling and intervention can improve the quality of life in the patients with breast cancer.

Objective: To detect P53 and Ki-67 protein,human papill om a virus (HPV),cytomegalovirus(CMV) and Epstein-Barr virus(EBV)in the warts of o ral mucosa from HIV-positive patients.Methods: The expression P53 and Ki-67 protein,HPV,EBV and CMV were detected by immunohistochemistry and PCR in 34 cases of oral mucosa warts from HIV-positve patients,33 cases of oral epithelia dysplasia and 45 cases of oral squamous cell carcinoma. Results:(1)The expression of P53 and Ki-67 protein in the cases of oral mucosa warts from HIV-positive patients were 23%and 76% re spectively,lower than those in oral suquamous cell carcinoma lesions from non- HIV individuals(62.8% and 97.8% respectively,P0.05).(2)The HPV infection in the warts of oral mucosa from HIV -positive patients was 88.2%,much higher than in oral suquamous cell carcinoma lesions (35.6%) and in dysplastic lesions (9.1%) from non-HIV individuals(P

Objective To investigate the association of thyroid carcinoma and urine iodine level in Urumqi region,intent to provide the evidence of individual iodine supplement of this region.Methods In this case-control study,there were 100 patients with thyroid carcinoma and 300 patients with normal thyroid function as the control group in Xinjiang Tumor Hospital between February 2012 and December 2012 as the case group.All the cases were detected for urine iodine concentration by arsenic-cerium catalytic spectrophotometry.Results The mean level of urinary iodine in the case group (272.69 μg/L) was higher than that in the control group (161.40 μg/L) (P ＜ 0.05).The level of iodine was excessive (urinary iodine ＞ 300 μg/L) in 34 ％ (34/100) patients in the case group and 10 ％ (30/300) patients in control group (P ＜ 0.05).Conclusion The average urinary iodine content of the thyroid carcinoma in Urmuqi region are generally higher than that of the healthy control group,which indicates that the iodine nutritional status in patients with thyroid carcinoma are better than that in the general population.The relationship between thyroid carcinoma and excessive iodine intake should be necessary for further study.

Objective The purpose of this study is to study the expression of miR -221 in cervical cancer tissues and its relationship with HPV infection .Methods HR-HPV infection was detected by HC2,and 30 cases of HR-HPV negative and 5 cases of HR-HPV positive cervical cancer tissues were collected .Mean-while,30 cases of normal cervical tissues in patients with benign disease were collected as control group .The ex-pression of miR -221was detected by RT -PCR,preliminarily investigating the relationship between miR -221 expression and the occurrence of cervical cancer and HPV infection .Through transfection of miR-221 and anti-miR-221 into HPV16-positive cervical carcinoma cell line Caski and HPV 16-negative cervical carcinoma cell line C33a,we observed the role of miR -221 on the migration and invasion of Caski cells and C 33a cells.Results Compared with normal cervical tissues , the expression of miR -221 in cervical cancer was significantly in-creased,the difference was statistically significant( P<0.01);and the expression of miR-221 was closely correl-ative to the patients with or without lymph node metastasis ,pathological grade and clinical stage ( P<0 .01 );the expression of miR-221 in HR-HPV positive cervical cancer tissues was higher than in HR -HPV negative cer-vical cancer tissues(P<0.01);transfection of miR -221 and anti-miR-221 could promote or downregulate C33 a and Caski cells migration and invasion ,and the changes between two groups had statistical significance ( P<0.05).Conclusion The increased expression of miR -221 in cervical cancer tissues is closely related to the oc-currence and development of cervical cancer and HPV infection .

Objective To evaluate the role of transurethral resection of the prostate(TURP)in early diagnosis of prostate carcinoma.Methods TURP were perforhaed on 16 suspected patients with prostate carcinoma,based on their mean serum PSA level(11.7 ng/ml),negative results of anal touch and needle system biopsies,or with lower urinary tract symptoms,or those biopsy was not fit.6 cases were diagnosed prostate carcinoma by pathology.3 cases underwent double orchieetomy and treated with anti-androgen drugs.2 cases were emasculated by medicines and treated with anti-androgen drugs.1 case underwent radical prostatectomy after neoadjuvant hormonal therapy.Results 6 cases(37.5%)diagnosed prostate carcinoma by pathology were followed up for 3 months to 2 years and were all alive.Lower urinary tract symptoms were relived in 2 patients who underwent TURP. Conclusion TURP play a important role in early diagnosis of prostate carcinoma in certain circumstances.The symptoms could be relieved by TURP in patients with lower urinary tract symptoms.

Objective: To investigate the expression of type Ⅰ collagen α1 chain protein (COL1A1) in triple negative breast cancer (TNBC), and its relationship with clinicopathological features and prognosis of TNBC. Methods: A total of 148 TNBC specimens were collected from the Affiliated Cancer Hospital of Xinjiang Medical University from 2013 to 2015. The mRNA expression of COL1A1 was detected by fluorescence quantitative RT-PCR and the protein expression of COL1A1 was detected by Western blot. The expression of COL1A1 and α-smooth muscle actin (α-SMA) in TNBC were detected by immunohistochemistry. The relationship between the expression of COL1A1 and clinicopathological parameters and prognosis of TNBC patients was analyzed. Results: The mRNA and protein expression of COL1A1 in MDA-MB-231 cells were 1.696±0.486 and 0.550±0.088, respectively, which were higher than those in MCF-10A cells (1.020±0.231 and 0.350±0.083, P=0.032, P=0.046). The mRNA and protein expression of COL1A1 in TNBC tissues were 1.632 ±0.598 and 0.733 ±0.068, respectively, which were higher than those in paracancerous tissues (1.041±0.316 and 0.612±0.016, P=0.003, P=0.039). The high expression rates of COL1A1 and α-SMA in TNBC tissues were 35.8% and 56.7% respectively, which were higher than those in paracancerous tissues (16.7% and 30.0%, P=0.041, P=0.037). The expression of COL1A1 was correlated with tumor size, TNM stage, lymph node metastasis, vascular invasion and α-SMA expression (all P<0.05). The median survival time in COL1A1 high expression group was 64 months, which was lower than that in low expression group (73 months, P<0.05). Multivariate analysis of Cox proportional hazard regression model showed that COL1A1 expression was an independent influencing factor for the survival of TNBC patients (HR=3.952, P=0.004). Conclusion The high expression of COL1A1 in TNBC is an independent prognostic factor of TNBC patients.

OBJECTIVE: To investigate the clinical characteristics and surgical treatment of Hashimoto's disease complicated with thyroid cancer. METHODS: Clinical data of 54 patients with Hashimoto's disease complicated with thyroid cancer were retrospectively analyzed, including clinical characteristics, surgical treatment, and short-term effects. RESULTS: The rate of Hashimoto's disease complicated with thyroid cancer was 14.9%, 54 out of in 362 patients with Hashimoto's disease. All the 54 patients had surgical treatment in proper thyroid region, took euthyrox after the operation and had 6 month to 4 year followup. One patient had a local recurrence and 3 had lymph node metastasis in the neck, and these 4 patients had second operation on the thyroid gland. No death occurred. CONCLUSION Hashimoto's disease complicated with thyroid cancer has no typical symptoms.Combined examination of anti-thyroid antibodies test, color doppler imaging, CT detection, isotope scan and core/fine needle biopsy may provide accurate diagnosis. Proper surgical treatment is effective for Hashimoto's disease complicated with thyroid cancer.

OBJECTIVE: To compare the trauma of neck dissection on the human body between two-striae incision and traditional "L" shaped incision by serum trauma cytokines. METHODS: Patients with differentiated thyroid carcinoma hospitized from December 2008 to July 2011 were divided into 2 groups according to their own will. The first group 26 patients) had two-striae incision and the second group 32 patients) had traditional "L" shaped incision. The serum level of interleukin(IL)-2, IL-6 and C-reactive protein (CRP) in all patients were examined 1 day before and 1, 3 and 5 days after the surgery. RESULTS: No statistical significance was found between the 2 groups, although level of IL-2 decreased 1 day after the surgery, but recovered to normal 3 days later. The level of IL-6 in both groups increased 1 day after the surgery, began to decrease 3 days after the surgery, and recovered to normal 5 days after the surgery. The level of CRP suggested statistical significance (P<0.05), which increased obviously 1, 3 and 5 days after the surgery. No statistical difference was found before or after the surgery between the 2 groups (P>0.05). After follow-up for 8-40 months, no local recurrence or lymph node metastasis was found. CONCLUSION Compared with the traditional "L" shaped incision, two-striae incision in neck dissection does not increase the serum level of trauma cytokines and trauma to human body after the surgery. Two-striae incision is an ideal surgical approach to differentiated thyroid carcinoma.
