Objective　To study radiotherapy in the treatment of uterine sarcomas and response to radiation in primary or recurrent uterine sarcomas. Methods　A total of 102 uterine sarcomas treated in the Cancer Hospital from May 1960 to June 1999. A retrospective review of 45 patients receiving surgery alone, 29 patients for postoperative radiotherapy, 4 radiotherapy alone, 24 recurrent sarcomas receiving radiotherapy. Results　The 5-year overall survival for 45 patients treated with surgery alone and 29 patients managed by postoperative radiotherapy were 56.7% and 58.6% respectively (P>0.05). The addition of radiotherapy significantly reduced the local recurrence rate from 42.2% to 20.7% （P<0.05）. The tumor was disappeared completely by treatment of radiotherapy alone in 3 patients of primary uterine cervix sarcomas. 1 patient was free of disease at 36 months. Other 2 patients died 9 and 11 months later because of distant metastases. The complete and partial response rate of radiotherapy was 50.0% for recurrent tumors. The radiotherapetic sensibility of endometrial stromal sarcomas, mixed mesodermal sarcomas and leiomyosarcomas was downward tendency in turn.Couclusions　The postoperation adjuvant radiotherapy reduced the pelvic recurrent significantly. Radiotherapy should be used in the treatment of uterine sarcomas as an important part of combination therapy.

Objective　To evaluate the effect of tamoxifen on the endometrium. Methods　Hysteroscopy and endometrial biopsies were performed in 26 patients with breast cancer receiving tamoxifen and having vaginal bleeding or endometrial thickness detected by ultrasound. In addition 78 women with postmenopausal bleeding without receiving tamoxifen underwent the same examination. Results　Thirteen (50.0%) patients receiving tamoxifen had endometrial or endocervical polyps, whereas 14 cases(17.9%) not receiving tamoxifen developed the polyps （P＜0.05）. Nine (34.6%) patients receiving tamoxifen had thyperplasias, which was significantly higher than that of women not receiving tamoxifen (P<0.05). Conclusions　The incidence of endometria disease in the patient with breast cancer receiving tamoxifen was increased. These patients should be closely monitored by transvaginal sonography and hysteroscopy.

Objective To explore whether the presence of juxtapapillary duodenal diverticula (JPDD) risks biliary stone disease and recurrence.Methods 829 patients undergoing ERCP in our hospital from Aug 2008 to Dec 2012 were divided into four groups:biliary stone disease (n =609) non-stone biliary abnormality (n =124) common bile duct malformation with cholelithiasis (n =38) and normal control group (n =58).There were 206 patients with JPDD and 623 patients without JPDD.Biliary stoneformation,post-ERCP pancreatitis,cannulation failure,and stone recurrence were compared between those with JPDD and those without.Results The incidence of JPDD in biliary stone disease group (27.8％) was significantly higher than in non-stone biliary anatomical abnormality group (18.5 ％) (x2 =4.512,P ＜ 0.05).In biliary stone disease group,rates of post-ERCP pancreatitis were significantly higher in JPDD cases (33.7％) compared to those without JPDD (13.8％) (x2 =30.841,P ＜ 0.05).The cannulation failure rate was also higher in patients with JPDD (15.4％) compared to JPDD negative (6.8％) (x2 =0.731,P ＜0.05).Recurrence rates in biliary stone disease were significantly higher in patients with JPDD (19.5％) when compared to JPDD-lacking individuals (9.3％) (x2 =14.51,P ＜ 0.05).Conclusions JPDD is a risk factor for biliary stone formation.JPDD also is associated with post-ERCP pancreatitis,cannulation failure and biliary stone recurrence.

Porcine reproductive and respiratory syndrome virus (PRRSV) and porcine circovirus type 2 (PCV2) are very two important pathogens that have coursed huge economic losses in swine production in worldwide. In this study,a vector pCMV-TJM containing the full-length cDNA clone of PRRSV attenuated strain TJM-F92 was firstly constructed by PCR method. Then a gene sequence containing Afl II/Mlu I e restriction enzyme sites and a transcription regulatory sequence for ORF6 (TRS6) was inserted be- tween ORF7 and 3'UTR, yielding a expression vector pCMV-TJM-TRS. Subsequently, a plasmid pCMV-TJM-Cap was constructed by cloning of PCV2 ORF2 gene into the unique sites Afl II /Mlu I of pCMV- TJM-TRS plasmid DNA. Then three recombinant PRRSV, rTJM, rTJM/TRS and rTJM/Cap, were rescued by transfection of pCMV-TJM, pCMV-TJM-TRS and pCMV-TJM-Cap into Marc-145 cells, respectively,and confirmed by the genome sequence, restriction enzyme digestion, Western Blot and IFA. They all had the molecular markers which was different from the parent virus. The growth characteristics of the rescued viruses were similar to that of parent virus. rTJM/Cap could also express efficiently PCV2 Cap protein in Marc-145 cells. At passage 8, it still had PCV2 ORF2 gene which examined by RT-PCR. It indicated that the full-length cDNA clone of PRRSV attenuated strain TJM-F92 and recombinant PRRSV rTJM/Cap expressing PCV2 Cap protein were successfully constructed. It made an important foundation for studying on the pathogenic mechanisms of PRRSV and PRRSV-PCV2 vaccine in the future.

Objective To explore the recuperative effect of immunological function and nutritional status on the patients treated by immune enteral nutrition in early stage after severe multiple injury (SMI). Method The patients with SMI,in department of Trauma Surgery,Tongji Hospital,Tongji Medical College, Huazhong University of Science and Technology,between January 2006 to May 2007 were randomly divided into 2 groups: immune enteral nutrition group (IEN group, 20 cases), enteral nutrition group (EN group, 20 cases). The health persons served as the control group(15 cases) .Since 1st postinjury day, all patients were treated with nutritional support. The T-cell subgroup in periphera blood were detected by FCM and the level of PA, RBP, IL-2 and IL-4 in blood serum were detected by ELASA on the 1st, 3rd,5th, 8th postinjury day. Results After the treatment of IEN and EN,the serum levels of PA, RBP and the proportion of T-cell subgroup were significantly increased on the 8th postinjury day compared with on 1st postinjury day (P ＜ 0.01), but there were no differences between IEN group and EN group. The level of IL-4 were significantly decreased and the level of IL-2 were significantly increased in each group on 8th postinjury day, at same time, the level of IL-2 were significantly increased in IEN group compared with EN group (P ＜ 0.05), and the level of IL-4 were significantly decreased in IEN group compared with EN group (P ＜ 0.05). The duration of SIRS was transient and the infected complication was low on the patients treatment by IEN than EN. Conclusions On the patients with severe multiple injury, IEN was most ascendant than EN to improve the immunosuppression and clinical prognosis.

Objective To characterize the imaging features of mediastinal cysts and gain a better understanding of atypical manifestations of various mediastinal cysts and improve the level of diagnosis. Methods The CT and/or MR images(CT n=28, MRI n=26, CT and MRI n=10), surgical information, and pathologic material in 44 histopathologically proved cases of mediastinal cyst were retrospectively reviewed. Results The mediastinal cysts were located in the anterior mediastinum(n=13), middle mediastinum(n=18), anterior-middle mediastinum (n=2) and posterior mediastinum(n=11). Bronchogenic cysts and pericardial cysts were atypically located in 7/20(35%)and 5/6 respectively. The density of 42.9% cysts on CT was close to that of water. Each of the cysts had a high signal intensity that was equal to or greater than cerebrospinal fluid on T_2-weighted MR images. One cyst showed marked loss of signal on MR hydrography. The signal intensities of the cysts were variable on T_1-weighted images. The signal intensity of MRI was not homogeneous in 5 and the reasons were different. Fourteen cases were misdiagnosed. Conclusion 1.The cysts with soft-tissue attenuation on CT in the anterior and posterior mediastinum may be easily misdiagnosed as neoplasm. Pericardial cysts located in the paratrachea may be easily misdiagnosed as bronchogenic cysts .2. MRI can be used to diagnose the cysts with high density on CT.3. Heterogeneous signal on MRI and loss of signal on MR hydrography might be the reasons for misdiagnosis.

Objective To observe the changes of respiratory and hemodynamic functions in children with different age undergoing laparoscopic Nissen's fundoplication(LNF). Methods Thirty-three children with LNF were divided into three groups according to the age: group Ⅰ,1 to 12 months,n=13;group Ⅱ,1 to 3 years old,n=10;and group Ⅲ,4 to 7 years,n=10.Heart rate(HR),mean arterial pressure,Ppeak,compliance of the respiratory system(CRS) and end-tidal carbon dioxide pressure(PETCO2) were recorded 5 min before pneumoperitoneum(T0),10 min(T1),60 min(T2) after pneumoperitoneum and 10 min after deflation(T3),and parameters of blood gas analysis such as PaCO2 were measured at the same time. Results Compared with those at T0,HR,Ppeak,PETCO2 and the difference between PaCO2 and PETCO2(Pa-ETCO2)were significantly increased at T1 and T2,while CRS was significantly decreased.The most significant changes were found in group Ⅰ. Conclusion The changes of respiratory and hemodynamic functions are observed in children undergoing LNF,and anesthesia management should be enhanced for those within 1 to 12 months old who experience the most significant changes.

OBJECTIVE: To investigate the expression of signal transducer and activator of transcription 3 (STAT3) and phosphorylated STAT3 (p-STAT3) protein in papillary thyroid carcinoma (PTC), and to explore the correlation and significance between the expression of STAT3, p-STAT3 and epithelial-mesenchymal transition (EMT). METHOD: The expression of STATS3. p-STAT3, E-cadherin and Vimentin protein in 56 cases of PTC specimens and adjacent normal tissues specimens ware detected by immunohistochemistry. The correlation of the expression of STATS, p-STAT3, E-cadherin and Vimentin protein in PTC with clinicopathological characteristics was analyzed. RESULT: The positive rates of STAT3, p-STAT3 in PTC tissue were significantly higher than those in adjacent normal tissues specimens respectively (P < 0.01). The positive rates of E-cadherin in PTC tissues were remarkably lower, compared to adjacent normal tissues specimens (P < 0.01), however the positive rates of Vimentin in PTC tissues were remarkably higher, compared to adjacent normal tissues specimens (P < 0.01). The expression of STAT3, p-STAT3, E-cadherin and Vimentin protein were associated with lymph node metastasis and clinical stage (all P < 0.05). The expression of STAT3 and p-STAT3 was negatively correlated with E-cadherin expression (r = -0.494 and r = -0.364, P < 0.01, respectively), but positively with Vimentin expression (r = 0.533 and r = 0.377, P < 0.01, respectively) in PTC tissues. CONCLUSION PTC tissues have STAT3 protein activation and EMT phenotype, as were all correlated significantly with PTC invasion and metastasis. STAT3 signaling pathway activation might mediate EMT and then promote PTC invasion and metastasis.

OBJECTIVETo compare the efficacy of different points combination in the treatment of menopausal insomnia.

METHODSNinety-six cases of menopausal insomnia were randomized into 3 groups, Xinshu (BL 15), Shenshu (BL 23), Sishencong (EX-HN 1), Shenmen (HT 7), Sanyinjiao (SP 6) were chosen in the restore interaction between the heart and the kidney group (group A, 32 cases); Zhaohai (KI 6), Jiaoxin (KI 8), Shenmai (BL 62), Pucan (BL 61) were chosen in the acupuncturing qiao mai group (group B, 32 cases); auricular Shenmen (TF4) and sensitive spot at the distribution area of auricular vagus nervus were chosen in the ear acupuncture group (group C, 32 cases). Six days made one session and the treatments were finished after 4 courses. The polysomnography (PSG) and Pittsburgh sleep quality index (PSQI) were employed before and after treatment to evaluate the alleviation of insomnia.

RESULTSThe parameters of the sleep latency (SL), rapid wave sleep latency (RL) and sleep efficiency (SE) were significantly improved in the three groups, and the differences were statistically significant (P < 0.05, P < 0.01). The SL and awaking time (AT) in group C [SL (401.08 +/- 16.54) min and AT (4.87 +/- 2.64) times] were significantly superior to those in the other two groups [SL (50.36 +/- 18.47) min, (54.87 +/- 20.92) min, AT (5.98 +/- 2.11) times, (6.13 +/- 3.04) times, all P < 0.05]. The S(3+4) (%) in group C was also significantly higher than those in the other two groups (both P < 0.05). It was indicated by PSQI that the sleep quality of group C (0.78 +/- 0.12) was significantly superior to that in group B (1.32 +/- 0.29), the total score and cured and markedly effective rate in group C [(4.34 +/- 1.43), 68.8% (22/32)] were superior to those in group A [(7.48 +/- 3.09), 53.1% (17/32), both P < 0.05].

CONCLUSIONEar acupuncture has a better curative effect than the restore interaction between the heart and the kidney group and acupuncturing qiao mai group, it is worth of being promoted.
