Objective To evaluate accuracy of preoperative tumor grade and intracperative gross examination of myometrial invasion in patients with clinical stage Ⅰ endometriod adenocarcinoma for lymphadenectomy. Methods Clinic-pathological data were retrospectively collected from 687 patients with clinical stage Ⅰ endometriod adenocarcinoma who underwent operation in Women's Hospital, Zhejiang University School of Medicine from January 1999 to December 2008. According to postoperative histology diagnosis, accuracy of preoperative tumor grade by curettage and depth of myometrial invasion by intraoperative gross examination was evaluated, and clinic-pathological factors associated with accuracy were analyzed. Results Sensitivity, specificity, accuracy, false negative rate, false positive rate, and positive and negative predictive value for the prediction of needing for intraoperative lymphadenectomy in patients with clinical stage Ⅰ endometriod adenocarcinoma were 70. 4% ,80. 2% ,77.6% ,12.0%, 43.0%, 57.0% and 88.0%, respectively. Analysis of mutil-factors shown that patient age, tumor size, lymph node metastasis and extrauterine spread lesions were independent factors affected the accuracy of prediction(P ＜ 0. 05 ). Conclusion Prediction of needing for lymphadenectomy by preoperative tumor grade and intraoperative gross examination of myometrial invasion is reliable in clinical stage Ⅰ endometriod adenocarcinoma patients, while there is a highly false negative rate in prediction of not needing for lymphadenectomy, while other prognostic factors such as patient age, tumor size, lymph node metastasis and extrauterine spread lesion should be together considered.

BACKGROUND: Early clinical researches suggest that mediodespidine capsule can decrease blood pressure of patients with primary hypertension on the basis of yanggan qinggan pinggan technique.OBJECTIVE: To observe the effect of mediodespidine capsule on primary hypertension and angiotensin Ⅱ (Ang- Ⅱ ) of patients in the types of yin deficiency, yang excess and liver fire.DESIGN: Randomized controlled case observation.SETTING: Department of Cardiology, First Affiliated Hospital, Hunan University of Traditional Chinese Medicine.PARTICIPANTS: Patients were selected from the Inpatient Department and Out-patients Clinic of the First Affiliated Hospital of Hunan University of Traditional Chinese Medicine between April 1999 and April 2000. Inclusion criteria: Patients, who were diagnosed with the criteria of primary hypertension, who belonged to the types of yin deficiency, yang excess and liver fire, who could endure this test, who were coincidence with the criteria of mental-stress test, were all consent. Exclusion criteria: Patients who had severe congestive heart failure, atrophic arthritis and unable tolerance were excluded. There were 60 cases in total, including 29 males and 31females. All patients were divided into mediodespidine group and verapamil group with 30 in each group on the basis of randomly digital table.METHODS: Patients who had positive results of awaken mental-stress test were involved in this study. Cases in mediodespidine group were treated with mediodespidine capsule, which was made of tall gastrodia tuber, spine date seed and fourstamen stephania root at the dosage of 0.43 g/pill and were provided by the First Affiliated Hospital of Hunan University of Traditional Chinese Medicine (wei yao ji zi: 05-047, batch number: 990503), five pills each for 3 times a day. Cases in verapamil group were treatedwith verapamil (40 mg/pill, Shanghai Huanghe Liya PharmaceuticalCompany Limited,batch number: 980301B) 80 mg each for 3 times a day. The course in both groups was 4 weeks. ① Effect of blood pressure: Average value of blood pressure tested for 3 successive days were regarded as the blood pressure before treatment, and average value of blood pressure tested for 3 times after treatment was regarded as the blood pressure after treatment. ② Effect of symptom:Scores were recorded as four levels according to main symptoms, such as vertigo, headache, pain and weakness of waist and knees, before and after treatment. ③ Values of Ang- Ⅱ were measured with radioimmunoassay before and after cold pressor test. Effect on Ang- Ⅱ was evaluated with effect of decompression, effect of clinical symptom and criteria of clinical effect.MAIN OUTCOME MEARUSES: Clinical symptoms, values of blood pressure, heart rate and Ang- Ⅱ before and after cold pressor test.RESULTS: A total of 60 patients with primary hypertension were involved into the final analysis.① Totally effective rate of clinical symptoms of patients in mediodespidine group was higher than that of patients in verapamil group, but the effect of decompression was not significant between the two groups (P ＞ 0.05). ② There was remarkably significant difference of heart rate in both groups before and after treatment (P ＜ 0.01), especially the decrease in verapamil group was great, and there was significant difference (P ＜ 0.05). ③ Values of systolic pressure and diastolic pressure were decreased in both groups after cold pressor test (P ＜ 0.01), but there was no significant difference between the two groups (P ＞ 0.05). ④ There was no significant difference in clinical effect between the twogroups (P ＞ 0.05).⑤ After treatment, concentration of Ang- Ⅱ at basic level in both groups was decreased, and there was significant difference between them (P ＜ 0.01);concentration of Aug-Ⅱ was decreased in both groups after cold pressor test as compared with that before treatment, but there was no significant difference between them (P ＞ 0.05).CONCLUSION: Mediodespidine capsule can decrease blood pressure stably, and the effect is stronger than that of verapamil at the aspect of decompression and improving symptoms. Blood pressure of patients with primary hypertension in the types of yin deficiency and yang excess or liver fire can be decreased by decreasing the level of plasma Ang-Ⅱ to a certain degree.

Objective To study the clinical significance of the novel tumor marker Cytokerantin?19?fragment( CYFRA 21?1) of peripheral blood in patients with esophageal cancer. Methods The CYFRA 21?1 level in peripheral blood of 72 patients with benign tumor of esophagus or reflux esophagitis and 60 patients with esophageal cancer was examined before and 7 days after operation by enzyme?linked immuno sorbent assay ( ELISA) . At the same time, patients with esophageal cancer were followed up for 3 years, and the level of CYFRA21?1 was examined. Results (1)Before the operation,the level of CYFRA 21?1 was 0-3. 30 μg/L in 51. 67%( 31/60 ) of the patients with esophageal cancer, higher than that of the control group ( 16. 67%(12/72),χ2=3. 88,P<0. 05). (2)Before the operation,the level of CYFRA21?1 in patients with esophageal cancer,stage Ⅰ,Ⅱ and stage Ⅲ,Ⅳ were (3. 27±0. 33) μg/L and (4. 88±1. 21) μg/L,and of the control group was (2. 24±1. 17) μg/L. The levle of CYFRA21?1 in patients with esophageal cancer,stage Ⅰ,Ⅱ andⅢ,Ⅳ were significantly higher than that of the control group( t=2. 37,2. 00,P<0. 05) . ( 3) On the 7th day after operation,the level of CYFRA21?1 was (2. 26±1. 16) μg/L,and the difference was not significant compared with the control group(t=0. 95,P>0. 05). The level of CYFRA21?1 with the palliative resection of esophageal cancer was (3. 31±0. 66) μg/L,and the difference was significant compared with the control group(t=4. 33,P<0. 05) . ( 4 ) After 3 years of follow?up, the factors affecting the survival rate of esophageal cancer were as following:the pathologic stages of tumor(OR 4. 423,95%CI 1. 943-4. 972,P<0. 05),types of operation(OR 0. 023,95%CI 0. 012-0. 036,P<0. 05),the level of CYFRA21?1 before operation(OR 6. 798,95%CI 4. 328-8. 105,P<0. 05),and the decreased level of CYFRA21?1 after operation(OR 0. 117,95%CI 0. 074-0. 202,P<0. 05) . ( 5) During the follow?up period,the level of CYFRA21?1 in patients with local recurrence and distant metastasis of esophageal carcinoma was (7. 97±0. 44) μg/L,significantly more than that of the control group(t=5. 11,P <0. 05) . Conclusion CYFRA21?1 is a useful tumor marker in the positive rate of preoperative diagnosis of esophageal cancer, postoperative monitoring of recurrence, distant metastasis and prediction of prognosis.

Objective To evaluate clinical and pathologic factors associated with pelvic lymph node metastasis in patients with early-stage squamous cell carcinoma of the uterine cervir.Methods From February 2004 to January 2007,135 patients with stage Ⅰ b-Ⅱ a cervical squamous cell carcinoma in Women's Hospital,School of Medicine,Zhejiang University,were retrospectively studied.The relationship between pelvic lymph node metastasis and age,clinical stage,tumor size,grade of differentiation,depth of muscular invasion,lymphatic vascular space invasion,pretreatment level of serum squamous cell carcinoma antigen,pretreatment plasma level of fibrinogen,pretreatment leveh of hemoglobin and platelet were evaluated by univariate and multivariate analyses.Results Totally 3996 lymph nodes were dissected in 135 patients,with an average of 29.6 lymph nodes in each patient.12.6%of the patients(17/135)had metastasized pelvic lymph nodes.Univariate analysis indicated that tumor size(P=0.003),depth of muscular invasion(P=0.004),vasular space invasion(P<0.01),pretreatment levels of platelet(P=0.006)and fibrinogen(P<0.01)were significantly related to pelvic lymph node metastasis.Multivariate logistic regression analysis showed that lymphatic vascular space invasion(OR:3.674,95%CI:1.825-7.393,P<0.01)and pretreatment plasma level of fibrinogen(OR:4.568,95%CI:1.779-11.725,P=0.002)were significantly related to pelvic lymph node metastasis in patients with early-stage squamous cell carcinoma of the uterine cervix.Conclusion In early-stage cervical squamous cell carcinoma,lymphatic vascular space invasion and higher pretreatment plasma levels of fibrinogen are risk factors of pelvic lymph node metastasis.

OBJECTIVE:To explore the effect of prophylactic use of vitamin B6 with chlorpheniramine on the adverse reactions in fundus fluorescein angiography (FFA). METHODS:326 patients with FFA were randomly divided into observation group and control group. Observation group was orally given Vitamin B6 tablet 10 mg 30 min before angiography+Chlorpheniramine maleate tablet 4 mg;control group was orally given Metoclopramide tablet 10 mg+Chlorpheniramine maleate tablet 4 mg. The occurrence time and incidence of adverse reactions in 2 groups were observed and correlation analysis was conducted. RESULTS:There was no significant difference in the occurrence time of adverse reactions between 2 groups(P>0.05);the incidence of adverse reactions in observation group was significantly lower than control group,the difference was statistically significant(P<0.05). The correlation analysis of adverse reactions in control group showed the occurrence of adverse reactions had no correlation with age and gender of patients(P>0.05). CONCLUSIONS:Prophylactic use of vitamin B6 with chlorphenir arnine can reduce the occurrence of adverse reactions in FFA.

Objective To evaluate the role of miR219‐2‐3p in gastric cancer and the underlying mechanisms .Methods Real time RT‐PCR was employed to quantify the expression level of miR219‐2‐3p in matched tissues of 82 patients .In vitro cell proliferation , the expression of tumorgenesis related protein ERK1/2 was performed by overexpressing miR‐219‐2‐3p in gastric cancer cell line MGC803 .Results The expression level of miR‐219‐2‐3p significantly decreased in late stage gastric cancer (P< 0 .05) .The cell proliferation rate was significantly reduced in gastric cancer cell lines overexpressing miR‐219‐2‐3p .Furthermore ,the expression level of p‐ERK that activated form of ERK was significantly decreased whereas the total level of ERK was unchanged after overex‐pressing of miR‐219‐2‐3p in MGC803 cell lines .The expression level of p‐ERK was also increased in gastric cancer tissues .Conclu‐sion miR‐219‐2‐3p may acts as a tumor suppressor in gastric cancer by decreasing the activity of ERK 1/2 signaling pathway .

Objective To detect brain structural difference between children with unexplained mental retardation and children with typically normal development. Methods The high-resolution magnetic MR imaging were obtained from 21 children with unexplained mental retardation and 30 age-matched control children without intellectual disabilities. Voxel-based morphometry analysis with an optimization of spatial segmentation and normalization procedures were applied to compare differences of gray matter volume between the two groups. The total and regional gray matter volume were compared between the two groups with independent t test. Meanwhile, correlation was conducted to analyze the relationship between the total gray matter volume and intelligence quotient (IQ) with partial correlation test. Results The total gray matter volume was significantly increased in the mental retardation children [(1. 012 ±0. 079) × 106 mm3]in relative to the controls [(0. 956 ± 0. 059) × 106 mm3, t = - 2. 80, P ＜ 0. 05]. Compared to controls,children with unexplained mental retardation showed significantly increased gray matter volume in different regions, including the bilateral thalami, the bilateral superior frontal gyri, the bilateral gyri rectus, the bilateral temporal poles, the right inferior frontal gyrus, right parahippocampal gyrus and the right cerebellum. No correlation was detected between the total gray matter volume and IQ in children with mental retardation (r = 0. 078 ,P ＞ 0. 05). Conclusions VBM would detect the gray matter abnormalities that were not founded in routine MR scanning. The increase of gray matter volume in the frontal-thalamus network might indicate the delayed maturation of the brain development. This might be one of the causations of mental retardation in children.

Objective The aim of this retrospective study was to analyze the role of surgery in the management of limited-stage-Ⅱ small cell lung cancer.Methods A retrospective review of 82 patients with limited-stage Ⅱ small cell lung cancer between January 2001 and December 2009 was performed.The prognostic impact of different therapy and the clinicopathologic factors were analyzed.Using SPSS 16.0 statistical software for data analysis.Log-rank test for the difference of survivale rate.Using the Cox model for muliti-factor survival analysis.Chi-square test for local recurrence and distant metastasis rate.Results The overall median survival time and the 1-,3-,and 5-year overall survival rates were 27.0 months,62.1％,35.9％,and 21.0％,respectively.Median survival was 34.0 months in surgical patients vs 16.0 months in nonsurgical patients (P =0.000).Median survival after lobectomy or pneumonectomy was significantly longer than after wedge resection (P =0.048).However,survival after wedge resection was still significantly longer than survival in nonsurgical patients(P =0.024).Survival analysis confirmed that the operation,chemotherapy and radiotherapy were showed to be independent prognostic factors.The local-regional recurrencer rates of lobectomy or pneumonectomy group was lower than wedge resection group(P =0.030).The distant metastasis rates of lobectomy or pneumonectomy group was lower than nonsurgical grou (P =0.021).Conclusion This study suggests that lobectomy or pneumonectomy combined with adjuvant radio-chemotherapy should be recommended for patients with limited-stage Ⅱ small cell lung cancer.

Objective To analyze the association of serum CA125 level at the different phases with recurrence and survival, for providing simple and efficient methods about predicting recurrence and prognosis in epithelial ovarian cancer.Methods The clinical-pathological data from 151 patients were collected, who were histologically confirmed as primary ovarian cancer between Jan 2002 and Dec 2005.All the patients were followed up.The relationship between serum CA125 level at different phases and clinical-pathological data were analyzed, including prognostic associated factors, 2-year or 5-year recurrent rate, 5-year survival rate, progression-free survival times, and overall survival times.Results Serum CA125 level at pre-surgery and the end of 3-course chemotherapy were associated with most of the clinical-pathological parameters,included stage, pathological grade, amount of ascites, residual tumor size, type of recurrence, 2-year and 5-year recurrent rate, and 5-year survival rate ( all P ＜ 0.05 ).Progression-free survival and overall survival times were shorter in the patients with higher CA125 level at pre-surgery or abnormal CA125 level at the end of 3-course chemotherapy (P ＜0.01 ).There was no relationship between the ratio of CA125 level at pre- and post-surgery and recurrence or prognosis ( all P ＞ 0.05).Conclusion Serum CA125 level at pre-surgery and the end of 3-course chemotherapy can be used for predicting the recurrence and prognosis of epithelial ovarian cancer.

Objective:This study aims to investigate the correlation between the number of resected lymph nodes (LNs) and the prognosis of patients with node-negative non-small cell lung cancer (NSCLC). Methods:A retrospective review of 305 patients with NSCLC, who received curative resection between January 2004 and December 2009, was conducted. All patients were proved without lymph node involvement histopathologically. The prognostic impact of the number of negative LNs and the clinicopathologic factors were analyzed. Results:The overall median survival time and the 1-, 3-, and 5-year overall survival rates were 60.0 months, 76.1%, 59.3%, and 47.1%, respectively. Survival analysis confirmed that the number of negative LNs, T staging and the stations of the mediasti-nal lymph nodes dissected were showed to be independent prognostic factors. Patients with a high number of negative LNs had better overall survival than patients with a low number of negative LNs (P<0.05). The patients with dissected LNs counts of more than 11 for cases with pTl~2 tumor (P<0.05) and more than 16 for cases with pT3 tumor (P<0.05) had better long-term survival outcomes. The post-operative complication rate was 12.1%, which was not significantly correlated with the number of dissected lymph nodes (P>0.05). Conclusion:The number of negative lymph nodes is an independent prognostic predicting factor for node-negative NSCLC. Sufficient dissection of LNs is recommended to improve the survival of the patients with node-negative NSCLC.
