Ovarian epithelial cancer is the most common type of ovarian cancers. It can be further classified according to the histopathology and cell differentiation of the tumor, which are key factors determining the biologic behavior and prognosis of ovarian epithelial cancer. Understanding the subtype-specific histopathology and molecular biology of ovarian epithelial cancer may provide clues to novel tumor markers for early detection and new therapeutic intervention strategies.

Purpose:To study the expression of CK19 and CK2 0mRNA in peripheral blood patients with FRGO Stage ⅠA to ⅡA cervical carcinoma and to investigate its clinical significance. Methods:Using the reverse transcription polymerase chain reacti on(RT-PCR),CK19 and CK20mRNA expression was examined in peripheral blood fro m 250 patients with early cervical carcinoma before operation,50 Patients with benign gynecological tumors and 18 healthy volunteers. In 250 patients,possible correlations between clinical pathological factors were analyzed. Results:The positive expression rates of CK19 and CK20mRNA were 36% and 24% in 250 cervical carcinomas respectively,in comparison with 3.0% an d 0% with benign gynecological tumors and all subjects in healthy volunteers wer e negative; The expression of CK19 and CK20 mRNA were significantly correlated w ith lymph vascular space involvement,but was not associated with prognostic fac tors including stage,differentiation,pathological types ,lymph node metastasis ,bully tumor size . In patients with CK19 mRNA(+)/CK20 mRNA(+),the rate of lymp h node metastasis and vascular space involvement and recurrence outside the pelv is was significantly higher than that of patients with CK1R mNA9(-)/CK20 mRNA(- )(P

Background and purpose:To evaluate the treatment regimens used for patients with yolk sac tumors of the ovary and prognostic factors in our hospital. Methods:Clinical data for the patients with yolk sac tumors of the ovary were analyzed retrospectively. Patients were divided into four groups: patients in A group received nonsparing surgery and platinum-based chemotherapy; in B group received nonsparing surgery and non-platinum-based chemotherapy; in C group received fertility-sparing surgery and platinum-based chemotherapy; in D group received fertility-sparing surgery and non-platinum-based chemotherapy. 5-year survival rate and prognostic factors were analyzed.Results:The overall 5- year survival rate was 69.2 %. The 5- years survival rates were 81.8 %, 40.0 %, 82.6% and 50.0% for A, B, C and D group, respectively. Platinum-based chemotherapy achieved significant survival benefit (82.4% vs. 44.4%, P0.05). Clinical stage, the size of residual tumor and Platinum-based chemotherapy were the mainly prognostic factors in multianalysis.Conclusions:Fertility-sparing surgery with a postoperative plainum-based chemotherapy should be the ideal modality for the treatment of yolk sac tumors of the ovary. Staging and tumor-reductive surgery were most associated with the prognosis of the patients.

Objective To evaluate our experience of minimal access parathyroidectomy for primary hy-perparathyroidism (PHPT) caused by parathyroid adenoma. Methods From Jan 2000 to Jan 2009, clinical data of 28 cases of PHPT treated by minimal access surgery were analyzed retrospectively. Results All patients except 3 had severe clinical manifestations, serum calcium and parathyroid hormonal (PTH) of all the cases were elevat-ed. The rate of accuracy of preoperation localization by the sestamibi scan combined with ultrasound was 100%.The pathological diagnoses of all the 28 cases were uni-gland parathyroid adenoma. Within the follow-up of 6 months, no case suffered complication and recurrence, the levels of serum calcium were normal or decreased slightly, and the levels of PTH were normal or elevated slightly but no higher than 2 times of normal PTH level. Conclusions Preoperative localization is very helpful by using combination of sestamibi and ultrasound scan. Minimally invasive parathyroidectomy is a kind of improving procedure for the localized parathyroid adenoma.

Objective:To summarize the CT signs and characteristics of bone-tumor.Methods:The CT and plain film signs of 71 cases of malignant bone-tumor and 19 cases of benign bone-tumor were analyzed.Results:The basic signs of bone-tumor were bone destruction, tumor bone formation,periosteal reaction,and soft tissue mass.Both benign and malignant bone-tumor had its characters of CT signs.Enhanced CT scans were advantageous in showing the tumor neighboring vessels.Conclusion:Our understanding is expanded and deepened for the signs of bone-tumor by CT scanning.This method provides much more accurate and comprehensive imaging informations than plain film.

Objective To investigate and analyze the attitudes of higher vocational nursing students toward death and the related effect factors.Methods Totally 324 nursing students in a higher vocational school in Shaanxi province were investigated with death attitude profile-revised scale.Contents of investigation included physical and mental health status,family members' attitude towards death,family form and ranking,religion,presence of suicidal thoughts,exposure to mass media reports about death,reading books about death,death fear,death escape,natural acceptance,approach acceptance,avoidance acceptance,etc.SPSS 16.0 was used for data entry and statistic analysis,mean and standard deviation for statistical description,t test and variance analysis for statistical inference.Results ①Higher vocational nursing students got the highest average score (3.93 ± 0.55) in the dimension of natural acceptance.②In the dimension of avoidance acceptance,the scores of nursing students with excellent and good physical and mental health were significantly lower than those of students with general physical and mental health (F=4.80,P=0.009) ; the scores of nursing students in single parent family were significantly higher than those of students in other family forms (F=4.59,P=0.004) ; the scores of nursing students with suicidal thoughts were significantly higher than those of students without (t=-4.77,P=0.000).In the dimension of death avoidance,the scores of nursing students whose family discussed death openly were significantly lower than those of students whose family never done so (F=6.88,P=0.001).In the dimension of natural acceptance,the scores of nursing students with religious beliefs were significantly lower than those of students without (t=2.52,P=0.012) ; the scores of nursing students who gained information of death from mass media were significantly higher than those of nursing students who never done so.(t=-3.85,P=0.000),which was the same in the dimension of approach acceptance (t=-3.48,P=0.001).Conclusions The majority of higher vocational nursing students can naturally accept death reality.Attitude of higher vocational nursing students toward death are influenced by physical and mental health,discussing death in family,family form,religious belief,suicidal thought and news or report about death from the mass media.

14mm.Results Group thick cycles had significantly lower implantation and pregnancy rates compared with group normal cycles(9.1% versus 13.5% and 18.8% versus 27.0%,respectively).Group thick cycles had significantly higher miscarriage rates compared with group normal cycles(50.0% versus 19.0%,respectively).Conclusion Increased endometrial thickness is associated with the decreased implantation or pregnancy rates and the increased miscarriage rates in IVF-ET.

Background and purpose:Uterine body invasion of carcinoma of the uterine cervix is not in the International Federation of Gynecology and Obstetrics(FIGO)staging system.Some reports suggested that uterine body invasion of carcinoma of the uterine cervix was an important prognostic factor.The aim of this study was to investigate the clinical characteristics and prognosis of the uterine cervix carcinoma with uterine body invasion.Methods:The clinicopathologic records of 406 patients with carcinoma of the uterine cervix of stage Ⅰb~Ⅱa who underwent radical hysterectomy and pelvic lymphadenectomy were retrospectively analyzed,the number of uterine body invasion was 69 in all cases.On the contrary,the negative number was 337.We studied the general condition(age of onset)and tumor conditions,including clinical stage,tumor diameter,pathological type,pathology differentiated degree,positive pelvic lymph nodes,deep stromal invasion,and lymph vascular space involvement.Results:In univariate survival analysis,the incidence of stage Ⅱa,non-squamous cell cancer(non-SqCC),tumor size≥4 cm,deep stromal invasion and positive pelvic lymph nodes were signifi cantly higher in carcinoma of the uterine cervix with uterine body invasion than those in control group(P

ObjectiveTo explore the screening and therapeutic efficacy of primary carnitine deficiency (PCD) in newborns and mothers.Methods164245 newborns and suspected mothers were investigated for PCD by tandem mass spectrometry (MS/MS).The overall epidemiology,prognosis,and follow-up of the screening program were investigated.ResultsTotally 55 suspected cases were identified at the primary screening stage.Four newborns and three mothers were confirmed as cases of PCD.The incidence rate of newborns was 1 ∶ 40076.All the patients showed normal growth and development during the follow-up.Blood free carnitine level was raised in all three mothers after treatment.ConclusionsScreening for PCD with MS/MS in newborns may represent a valuable procedure in preventive medicine by enabling early diagnosis and treatment before the onset of symptoms.This protocol is also highly efficient and applicable in diagnosis of mothers with PCD.

Objective To explore the safety of total thyroidectomy surgery on patients with thyroid carcinoma. Methods From Jan 1986 to Dee 2006, clinical data of patients who underwent total thyroidectomy (total thyroidectomy group) and sub-total or near-total thyroidectomy surgery (control group) for thyroid carcinoma were retrospectively analyzed to identify the incidences of complications, recurrent laryngeal nerve paralysis (RNLP) and secondary hypoparathyroidism in the two groups. Results In the control group there were 433 thyroid carcinoma patients who underwent sub-total or near-total thyroidectomy. Transient unilateral RLNP(13 eases), permanent unilateral RLNP(5 eases), transient hypoparathyroidism (11 cases) was diagnosed. There was no permanent hypoparathyroidism in this group. In the 70 cases of thyroid carcinoma patients receiving total thyroidectomy, there were 4 eases suffering from transient unilateral RLNP, one case from permanent unilateral RLNP (P > 0.05), and there were 7 eases from transient hopyparathyroidim (P < 0.01), 2 eases from permanent hypoparathyroidism (P < 0.05). Conclusion The incidence of RLNP after total thyroidectomy was not higher than that after subtotal or near-total thyroideetomy. Postoperative hypocalcaemia was the most common postoperative complication of total thyroidectomy. It is our belief that total thyroidectomy should be performed in selected patients.
