Aim To investigate the effect of effective fraction of Xie-Xin decoction and their compatibilities(EFX)on NF-?B and I?B expression of lung injury rats induced by LPS.Methods Rats were pretreated for 4 days with total flavones(TFL),total free anthraquinones(TFA),total conjugated anthraquinones(TCA),the high(low)dose of compatibility of TFL and TCA(A high,A low),the compatibility of TFL and TCA(B)and dexamethasone respectively 4 days,then injected intravenously with LPS to induce lung injury.6 rats were sacrificed respectively in every group at 1,2,4 h after LPS administration,and the right middle of the lung was harvested at every time point,the expression of NF-?B and I?B was evaluated by Western blot.Results TFA、A high and Dex can inhibit the nuclear translocation of NF-?B at 1,2,4 h(P

Objective To probe the effect of transareolar or mastoscopy assisted breast-conserving surgery combined with open axillary lymph node dissection in the treatment of breast cancer. Methods Nineteen patients, with breast cancer of a diameter cm from the nipple, were treated by transareolar or mastoscopy assisted breast-conserving surgery from August 2001 to November 2003.After the lipolysis and suction of axillary fat,open axillary lymph node dissection was performed. Results Intraoperative frozen pathological examination had showed positive margin in 1 case, in which an enlarged excision was required to obtain a negative result. Postoperative subcutaneous edema underlying the operated site occurred in 2 cases and was cured by needle aspiration and pressure dressing. Excellent cosmetic outcomes were obtained with symmetrical breast development and all the patients were satisfied with the treatment. Postoperative follow-up for 2～19 months (mean, 10.6 months) found no recurrence in the breast or the axillary fossa. Conclusions Breast-conserving surgery can be expediently carried out by means of transareolar incision or with the help of mastoscopy. The combination with open axillary lymph node dissection may give favorable effect.

Objective To evaluate the reproducibility of quality intima-media thickness(QIMT) and quality arterial stiffness (QAS) technique in assessment of carotid under different measuring methods.Methods Between December 2012 and January 2014,carotid QIMT and QAS examinations were carried out in 30 health volunteers.QIMT and QAS indicators included IMT in QIMT and distensibility coefficient (DC),compliance coefficient(CC),stiffness index α(α),stiffness index β(β),pulse wave velocity(PWV) in QAS.The measurement employed unilateral/once,bilateral/twice,and unilateral/twice methods.Using intra observer and inter-observer variability,the reproducibility was compared between different QIMT and QAS indicators and measuring methods.Results Extremely high level of intra-observer reproducibility was found for both QIMT and QAS technique (ICC＞0.8).QIMT also showed an excellent inter observer reproducibility (ICC＞0.8).In contrast,the reproducibility of QAS technique varied in different indicators (PWV ＞ β ≈ α ＞ CC ＞ DC) and method ( unilateral/once ＞ bilateral/twice ＞ unilateral/twice).Conclusions QIMT measurement was highly reproducible.Whereas the reproducibility of QAS technique varied in different indicators and methods.Due to low reproducibility,the study result did not support the clinical application of DC indicator and unilateral/once method.

Objective To investigate the function of triggering receptor expresses on myeloid cells receptor-1 (TREM-1) in lymphocyte differentiation and regulation of Aspergillus infected immunosuppressed rats.Methods Cyclophosphamide (CTX) was intraperitoneally injected and Fumigatus spore suspension was inhaled by percutaneous tracheostomy to establish the immunosuppressive invasive pulmonary aspergillosis (IPA) rat model.After 24 h, 48 h, 72 h and 96 h inoculation, rats were sacrificed.Lung tissue specimens, bronchoalveolar lavage fluid (BALF) , and plasma samples were collected.Plasma and BALF sTREM-1, plasma T cell-specific transcription factor (T-box expressed in T cells, T-bet) and eomesodermin(Eomes) were detected by ELISA.Biopsy specimens of lung tissue were used for periodic acid-schiff (PAS) staining and culture.Results The mortality rate of immunosuppressed rats after Aspergillus inhalation for 96 h was as high as 54.4％.Biopsy of lung tissue suggested acute inflammatory cell infiltration, interstitial lung congestion, alveolar structural damage, and visible Aspergillus hyphae in alveoli.Compared with normal control group[(110.50 ± 7.70)ng/L], plasma sTREM-1 in study groups were significantly increased [IPA : (146.77 ± 10.41) ng/L;CXT + IPA at 24 h : (226.00 ± 11.88) ng/L;CTX + IPA at 48 h : (200.77 ± 10.63) ng/L;P ＜ 0.05], so were T-bet levels [IPA : (561.17 ± 7.23) μg/L;CXT + IPA at 24 h : (647.00 ± 33.03) μg/L;CTX + IPA at 48 h : (619.23 ± 87.44) μg/L;control group : (340.03 ± 26.32) μg/L;respectively, P ＜0.05].However, plasma Eomes levels in IPA group, CTX + IPA at 24 h and 48 h were significantly lower compared with that in normal controls [IPA : (7.96 ± 0.65) ng/L;CXT + IPA at 24 h : (3.97 ± 0.35) ng/L;CTX + IPA at 48 h : (4.00 ± 0.74) ng/L;control group : (8.38 ± 0.51) ng/L;respectively,P ＜0.001].Compared with those in CTX + IPA vaccination after 24 h and 48 h, plasma sTREM-1 [(106.67 ±7.64)ng/L;(133.27 ± 32.79) ng/L] and T-bet [(299.64±63.07)μg/L;(398.02 ± 109.22) μg/L] in CTX + IPA at 72 h and 96 h inoculation were significantly lower (P ＜ 0.001).While Eomes [(8.38 ± 0.54) ng/L;(8.40 ± 0.70) ng/L] raised significantly higher (P ＜ 0.001).Compared with the control group, sTREM-1 levels in BALF of IPA + CTX 24 h, 48 h, 72 h, and 96 h groups were consistently high (P ＜ 0.05).Pearson correlation analysis showed that sTREM-1 and T-bet had a significant positive correlation (r =0.91, P ＜ 0.001), yet Eomes was negatively correlated with them (r =-0.788, P ＜ 0.001).Conclusions sTREM-1 in rat plasma and BALF appears highly expressed in immune compromised Aspergillus infected rat model.Plasma sTREM-1 is closely correlated with T-bet and Eomes levels, which suggests that TREM-1 may be involved in lymphocytic regulation and differentiation during fungal infection.

OBJECTIVE: To investigate the correlation of laryngeal squamous cell carcinoma (LSCC) and precancerous lesion with HPV infection subtypes and possible clinical relationship. METHOD: Eighty-three cases in paraffin embedded tissues were detected with thirty seven HPV subtypes by flow-through hybridization and gene chip (HybriMax), including 31 cases of laryngeal squamous cell carcinoma, 52 cases of precancerous lesions (29 cases of vocal cord leukoplakia and 23 cases of laryngeal papilloma), and 36 cases of vocal cord polyp as normal vocal mucosa were used as control. RESULT: The total positive rate of HPV was 19.4% in the group of laryngeal squamous cell carcinoma (6/31), 0 in vocal cord leukoplakia, 65.2% in laryngeal papilloma (15/23), and the control group were all negative, HPV virus subtype of HPV-positive laryngeal squamous cell carcinoma were all high-risk HPV16; and there were 6 HPV virus subtypes in laryngeal papilloma (8: HPV6,4: HPV52, 1: HPV11, 1: HPV18, 2: HPV45, 3: HPV16), individual mixing two or more subtypes infection. HPV infection of laryngeal squamous cell carcinoma and precancerous lesions has no statistically significant difference according to gender, high low-risk subtypes. CONCLUSION HPV infection related to laryngeal squamous cell carcinoma and precancerous lesions, but no significant correlation with the subtype distribution of high and low risk; HPV detection is making positive sense to clinical diagnosis of laryngeal carcinoma and precancerous lesions as well as the development of specific HPV subtype vaccine.

In this article, the Chinese Traditional Medicine and Materia Medica Subject Headings, Standards of the People's Republic of China - Classification and Codes of Diseases and Zheng of Traditional Chinese Medicine and the Chinese Terms in Traditional Chinese Medicine and Pharmacy were compared. Three standards were compared from the terminology quantity, content and classification. Each standard has its special feature. The compatibility and consistency are not strong in these standards. More authoritative traditional Chinese medicine terminology standards need to be established for the application in the clinical practice and scientific research.

Objective To summarize the sonographic features and pathological features of ovarian tumor during pregnancy. Methods One hundred and five women with 114 pathologically proved ovarian tumors during pregnancy in Peking Union Medical College Hospital were retrospectively recruited. According to pathological diagnosis, the clinical treatment, the result of the pregnancy and sonographic examinations were reviewed and analyzed. The sonographic features of benign tumors were compared with low-grade malignant tumors. Results Among the 105 pregnant women with a total of 114 ovarian tumors, 65 tumors were found by ultrasound exam. The other 49 tumors were found during cesarean section. The sonographic features of pathologically proved ovarian tumors include regular shape and well-deifned margins, with 58 of benign tumors and 7 of borderline or low-grade malignant tumors. Compared with borderline or low-grade malignant tumors, benign tumors manifested as strong echoes or high echogenic mass without papillae in the tumors (50/58). As for borderline or low-grade malignant group, tumors manifested as papillae within the tumors (5/7). Pathological classiifcation of the 114 ovarian tumors included 84 germ cell tumors, 19 epithelial tumors, 9 sex cord-stromal tumors, and 2 germ cell tumors combined epithelial tumors. Surgical treatments were performed in 7 cases during the ifrst trimester, while 11 cases during the second trimester, and 87 cases during the third trimester. Pregnancy outcome of the 105 pregnant women included term delivery in 82 cases, premature delivery in 18 cases, artiifcial abortion during ifrst trimester in 4 cases, and induced abortion during second trimester in 1 case. Conclusions Most ovarian tumors treated in pregnancy are benign. The sonographic features of benign tumors include regular shape with well-deifned margins, strong echoes or high echogenic mass within the tumors. While the sonographic features of borderline or malignant tumors include papillae within the tumors. Ultrasound assessment of ovarian tumors can help to determine the risk of malignancy and guide the surgical management.

Objective To retrospectively study the efficacy and side-effect of 125I seed implantation combined with endocrinal therapy in stage T3N0M0 prostate cancer.Methods The study included 22 patients with clinical stage T3 N0 M0 prostate cancer who were treated with transperineal 125I seed implantation guided by transrectal ultrasound,real time TPS and endocrinal therapy.The minimum peripheral doses (MPD) were 140-160 Gy.The median number of seeds was 74(26-90).The activity of each seed was 1.55 × 107 (1.30 × 107-1.85 × 107) Bq.11 patients were treated with orchidectomy,and 11 patients were treated with androgen deprivation therapy.Results All 22 patients completed the seed implantation successfully.The 5-year biochemical progression-free survival was 70.6％,and 5-year overall survival was 81.8％.2 patients were found biochemical failure in 12 months after seed implantation,and another 1 patient failed in 90 months.Endocrinal therapy was followed thereafter.After the seed implantation,the urinary complications of grade 1 and 2 were 54.5％ and 9.1％ respectively,and the rectum side-effect of grade 1 and 2 were 22.7％ and 9.1％.1 patient suffered rectal complication of grade 4.Conclusions Good effect and tolerance are observed in prostate cancer patients of stage T3N0M0 receiving 125I seed implantation plus endocrinal therapy.The treatment can be considered for those who refuse to receive external beam radiotherapy.

Objective To evaluate the contrast enhanced perfusion pattern of PTC micro-vascular imaging (MVI) quantitatively.Investigate the correlation between PTC MVI features and CD34 micro-vascular density (MVD).Methods Thirty-nine pathological and clinical confirmed sporadic PTCs were evaluated with real-time gray-scale contrast-ernhanced micro-vascular imaging under a low mechanical index.The micro-bubble agent was SoneVue.Of the 39 PTCs,33 were classical PTCs,6 were PTC with follicular variant (FVPTC).The △ ROI,which is the subtraction of peak echo intensity between the lesion region of interest (ROI) and normal thyroid parenchyma ROI,was used to evaluate the perfusion characteristics of PTC MVI quantitatively.The paraffined specimens were selected for immunohistochemical (IHC) staining for CD3,and the correlation between △ ROI and the CD34 were evaluated.Results △ ROI was strongly correlated with the CD34 expression (P=0.000),significant differences were detected in the distribution pattern of △ ROI value among different CD34 expression levels,no overlapping of the mean △ ROI values and the 95％ confidence intervals was found among the 3 CD34 expression levels.The PTC MVI perfusion was classified into 3 patterns,low perfusion,focal perfiusion and high perfusion,on the basis of combining△ ROI values with the peak ehco pattem in time-intensity curve.Conclusions The △ ROI is strongly correlated with the CD34 expression in papillary thyroid cancer.It can be used for the quantitative evaluation ofPTC MVI pattem and intensity as an objective indicator.

Objective To summarize the sonographic features and differential diagnosis points of mass-type cornual pregnancy. Methods The sonographic ifndings of 23 pathological proven mass-type cornual pregnancy cases enrolled in PUMCH from 2011 January to 2013 January were retrospectively analyzed. Results All pathological proven mass-type cornual pregnancy were located at one corner of the uterus presenting as a heterogenous outward mass. Well-deifned margins were found in 20 cases, and interstitial-line signs were found in 15 cases. The surrounding muscle thickness is 0.1-0.3 cm. Typical hyperechoic villi were found on sonography in cases with bloodβ-hCG>20 000 IU/L. On Doppler, the lesion showed abundant peripheral vascularity with low resistance in 22 cases, 9 lesions also showed abundant internal vascularity. Among 23 mass-type cornual pregnancy cases, 7 cases were misdiagnosed as gestational trophoblastic neoplasia (GTN) due to the similar sonographic characteristics including mixed-echo and abundant vascularity with low resistance. Sixteen cases were diagnosed by ultrasound preoperatively, with featured sonographic signs including mass located in the endometrial extension line;clear margin;peripheral vascularity;or detection of interstitial-line sign and typical villus. Conclusions Mass-type cornual pregnancy may be correctly diagnosed according to the location, boundary of the mass and the distribution of blood flow combining with clinical manifestation and bloodβ-hCG level. Transvaginal sonography could play an important role in diagnosis of cornual pregnancy.
