Objective To investigate the clinical manifestation and diagnosis of osteitis deformans. Methods Three male patients with characteristic manifestations of osteitis deformans were reviewed in this study. The ages of the patients were 51, 49 and 43 respectively. Two patients with pelvic lesions on X ray films presented symptomatic pain and malaise localized in hip, one complained of tibial bowing deformity. The typical radiographic characteristics were bone enlarged size, increased bone mineral density with uneven distribution; the bone trabeculae were usually coarse and arrayed irregularly like a grid. All patients underwent the diagnostic biopsy. Under microscopic observation, the bone structures were arranged disorderly, the trabeculae were thickened and enriched with osteoclasts and osteoblasts, irregular blue cement line were also seen in thickened trabeculae, the bone marrow were replaced by the fibrovascular connective tissue. All patients were given calcitonin and diphosphonates as medical treament. Results In the follow up period of an average of 16 months(range 3-26 months), one patients had pain relief at lesioned hip but functional limitation remained, the others did not have any sign of malignant progression. The serum alkaline decreased dramatically and the involved bone did not present with deteriorated change. They were working as usual. Conclusion Osteitis deformans is a disorder of bone architecture resulting from disturbance in the rate of bone turnover; typical radiographic and pathologic feature is the important points for definite diagnosis of osteitis deformans.

[Objective]To evaluate the effectiveness of biopsy of bone lesions.The factors that might effect on the clinical utility were analyzed in order to find out the independent factor for clinical effectiveness.Also we evaluated the effects of these factors on the open biopsy with needle biopsy previously done.[Method]We retrospectively reviewed 206 cases performed at our institute between June 2003 and Oct 2006,including percutaneous core-needle biopsy or open biopsy.The biopsy result was classified as correct,nondiagnostic,or incorrect.The biopsy results were considered clinical useful if they were correct and not useful if they were nondiagnostic or incorrect.We identified the independent risk factor by analyzing whether the characteristics including biopsy methods,lesion position,myxoid,lesion type reduced the effect on the clinical utility and increased the probability of proceeding to subsequent open biopsy.[Result]In 206 patients,one hundred and forty-seven cases(71.4%)underwent core-needle biopsy.Forty-seven cases(22.8%)underwent open biopsy and twelve cases(5.8%)had open biopsy with needle biopsy first.One hundred and seventy-six cases(85.4%)patients had clinical useful results.Eighteen cases(8.7%)were nondiagnostic,and twelve cases(5.8%)were incorrect.Myxoid histology was identified of independent risk factor on the clinical utility by logistic regression(P=0.02).[Conclusion]Most cases of bone lesions can be diagnosed by core-needle biopsy or open biopsy.The myxoid histology is associated with decrease clinical accuracy;No single characteristic cause increase probability of open biopsy.Correct diagnose of bone lesions requires combining biopsy,radiology and clinical data.

ObjectiveTo investigate the clinicopathological features of the needle biopsies of prostatic lesions and to evaluate the value of 34?E12 immunostaining for the diagnosis of prostatic carcinoma.MethodsThe clinical data,levels of serum PSA and HE slides of 103 cases of the needle biopsies of prostatic lesions were reviewed.Immunohistochemical stains for 34?E12 were performed.ResultsThe morphological features revealed 36 cases of benign prostatic hyperplasia(BPH),9 cases of low grade prostastic intraepithelial neoplasia (PIN I)and 34 cases of prostatic carcinoma(PC),24 cases of high grade PIN(PINⅡ and Ⅲ) have been suspected of carcinoma.With immunohistochemical stain,all cases of BPH were strongly reactive for 34?E12 while 32 cases of prostatic carcinoma were negative;14 of 24 cases of high grade PIN were negative for 34?E12 and could be diagnosed as PC.The rest 10 of high grade PIN were interruptedly positive in the basal layer for 34?E12.In the 30 cases of prostastic carcinoma,serum PSA levels of 25 cases was over 10 ng/ml and over 50 ng/ml in 15.ConclusionsThe pathologic diagnosis should based on gland architectures and cytologic features.34?E12 negative expression and elevation of serum PSA are also the important criteria for the diagnosis of prostatic carcinoma.

Objective To discuss the treatment and prognosis of multifocal osteosarcoma. Methods Between January 1998 and June 2005, nine patients(seven males and two females), six with synchronous multifocal osteosarcoma and three with metachronous multifocal osteosarcoma were treated in our department. The diagnosis of multifocal osteosarcoma was confirmed by clinical presentation, radiology and pathology. Eight of the nine patients received chemotherapy with adriamycin(60 mg/m2), cisplatinum(100 mg/m2), high-dose methotrexate(8-12 g/m2), vincristine(1.4 mg/m2), ifosfamide(12.5 g/m2), and G-CSF. Based on the response to primary chemotherapy, further chemotherapy plans were made, and different operations were done to control local lesions or to relieve symptoms. Arsenous acid, paclitaxel and VP-16 were used in patients who responded poorly to primary chemotherapy. Results One patient who given up remedy was died in systematic fail due to the cancer after 5 month, five patients who were diagnosed synchronous multifocal osteosarcoma died from progressive disease in 3.5 to 17 months (mean time was 9.8 months). Only two of them had a good response to chemotherapy and had finished at least four cycles of chemotherapy,and they had a better survival time of 15 and 17 months respectively. Three patients with metachronous multifocal osteosarcoma had a better prognosis. After a two-year follow-up, two lived with disease and one lived without disease. Conclusion The prognosis of patients with multifocal osteosarcoma is poor, and patients with metachronous multifocal osteosarcoma have a relatively better prognosis. To improve the prognosis of patients with multifocal osteosarcoma, aggressive chemother-apeutics are needed.

Objective To evaluated the role of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) in the diagnosis of thoracic tuberculosis.Methods The study was retrospective,from September 2009 to September 2012,38 patients who underwent EBUS-TBNA were finally diagnosed of thoracic tuberculosis,with enlarged hilar or mediastinal Iymph nodes on chest enhanced computed tomography(≥ 1.0 cm).Patients in whom EBUS TBNA was nondiagnostic subsequently underwent surgical biopsy.All the patients had a minimum of 6 months clinical and radiologic follow-up.Results EBUS-TBNA was performed on a total of 88 lymph node stations in 38 patients.Of the enlarged lymph nodes,60(68.18％) were located in the mediastinal region and the remaining 28 (31.82 ％) around the hilum or interlobar area.Of the 38 patients,EBUS-TBNA achieved definitive diagnosis in 34 patients(89.47％).EBUS was well tolerated by all of the patients with no complications.Conclusion EBUS-TBNA is a safe procedure with a high yield for the diagnoses of thoracic tuberculosis.

Objective To explore the correlation between serum hs-CRP and β-cell finction in patients with gestational diabetes mellitus(GDM).Methods The levels of hs-CRP in 60 patients with GDM(GDM group)and 30pregnant women with normal glucose tolerance(NGT group)were detected.Insulin resistance was assessed by the homeostasismodel insulin resistance index(HOMA-IR),Insulin secretion by the homeostasis β-cell funetiOn index(HOMA-β).Results The levels of hs-CRP and HOMA-IR were higher in GDM group than in NGT group.There was significant difference between two groups(P＜0.01);HOMA-β was lower in GDM group than in NGT group,there was significant difference between two groups(P＜0.05).The level of hs-CRP was correlated with age,pre-pregnant bodymass-index(BMI),screening BMI,fasting blood glucose(FBG),fasting insulin(Fins),and HOMA-IR(r=0.222,0.649、0.862、0.923、0.935、0.941,P＜0.05 or P＜0.01),but was inversely related with HOMA-β(r=-0.872,P＜0.01).Multiple stepwise regression analysis indicated that HOMA-IR and HOMA-β was the most important effect factors of hs-CRP.Conclusion The level of hs-CRP increased in women with GDM.which was related to insulin resistance(IR)and insulin secretion,and it maybe participate in the pathogenesis of GDM.

Objective To discuss the potential relationship between endometrial serous carcinoma (ESC) and tubal epithelial lesions by pathologic examination of fallopian tubes with ESC. Methods A total of 30 cases of typical ESC were reexamined and chosen by the pathologist. In each case, bilateral fallopian tubes were submitted to examination of pathologic morphology and immunostaining for p53, annexin Ⅳ(ANX-Ⅳ), human epidermal growth factor receptor 2(HER2)/neu, and high-mobility group protein A2 (HMGA2). Results Fallopian tubal epithelial lesions were found in 15 cases, including 9 cases tubal serous carcinoma, 2 cases serous tubal intraepithelial carcinoma (STIC) and 2 cases epithelial hyperplasia. Both sides of tubal serous carcinoma and STIC were found in 1 case. The results showed the positive expression for p53 in 26(87%)out of 30 endometrial malignant specimens tissues and 9(30%)tubal tissues samples (P>0.05). Twenty-five(83%)endometrial malignant specimens tissues and 6(20%)tubal tissues samples showed the positive expression of ANX-Ⅳ. Twenty-one(70%)endometrial malignant tissues and 7(23%) tubal tissues showed the positive expression of HER2/neu. Twenty-five(83%) endometrial malignant tissues and 6(20%)tubal tissues showed the positive expression of HMGA2. While, there were significant differences among the expression of three proteins between endometrium and the fallopian tube site (all P<0.05). Conclusions STIC may be associated with the occurrence of ESC. The expression of p53 was positively correlated between the fallopian tube and the endometrium. ANX-Ⅳ,HER2/neu and HMGA2 were extensively expressed in ESC.

Objective To observe the satisfaction of obtaining endometrial tissue in using endometrial sampling device and explore the influence for pathology diagnostic accordance rate,and to discuss the problem needs to focus in obtaining endometrial tissue with endometrial sampling device for endometrial cancer and precancerous lesion screening.Methods Totally 204 cases using endometrial sampling device with the subsequent diagnostic curettage,hysteroscopy,or hysterectomy were collected.A comparison of pathological diagnosis between two methods was made.The relationship among specimen quantity,proficiency,pathological types and diagnostic accordance rate were analyzed.Results The diagnostic accordance rate of endometrial cancer and precancerous lesion of two methods was 67％ (20/30).92.2％ (188/204) cases successfully got the endometrial glands,77.0％ (157/204) cases got ≥5 specimens of glands and 62.3％ (127/204) cases got ≥10 specimens of glands.When obtaining ≥5 but＜ 10 endometrial glands,the diagnostic accordance rate was 76.7％ (23/30); however,obtaining ≥10 endometrial glands,the diagnostic accordance rate was 92.9％ (118/127).The degree of specimen satisfaction of the first phase was lower than the second phase.Conclusions Obtaining ≥5 endometrial glands in using endometrial sampling device could satisfy the requirement of the basic pathological diagnosis.The proficiency of sampling and the pathological types could influence the degree of specimen satisfaction,and then influence the diagnostic accordance rate.
