Objective To evaluate the efficiency of levonorgestrel-releasing intrauterine system (LNG-IUS) in the treatment of recurrent endometriosis after conservative surgery or conservative surgery combined with medical treatment. Methods Twenty-three patients with recurrent endometriosis after conservative surgery or conservative surgery combined with medical treatment were treated by LNG-IUS. All patients rejected further operation and had no desire of fertility. The visual analogue scale (VAS) scores of pain, menstrual model, weight and serum CA125 level and the volume of ovarian endometriotic cysts before and after 3, 6, 12, 24 and 36 months of treatment were recorded and compared. Results ( 1 ) VAS score:after 12 months of using LNG-IUS, dysmenorrheal, chronic pelvic pain or dyspareunia were relieved significantly. VAS score were dropped from 5.9 ± 2. 3,4. 3 ± 2.0 to 1.0 ± 0. 7,1.4 ± 1. 1 ( P ＜ 0. 01 ). ( 2 )Volum of cysts :after 6 months of using LNG-IUS, the volume of recurrent ovarian endometriotic cysts in 11 patients were reduced from ( 11.4 ± 6. 1 ) em3 to ( 5. 5 ± 3.4 ) em3 significantly ( P ＜ 0. 01 ). At 12 months of follow-up, it suggested that 2 patients' ovarian endometriotic cysts disappeared. At 24 months follow-up,9 patients ovarian endometriotic cysts disappeared ( 3 ) CA125: serum CA125 decreased from ( 65.5 ± 19. 6 )kU/L to (42. 1 ± 13.6) kU/L at 6 months after treatment remarkably (P ＜ 0. 01 ). Continued to decrease after 12 months and then become steady. Irregular bleeding and spotting was the main side effects, weight gain was also observed in few patients. Conclusions LNG-IUS could be used in treatment of recurrent endometriosis after conservative surgery or conservative surgery combined with medical treatment effectively. It could relieve pain, reduce the level of CA125 and decrease the size of ovarian endometriotic cysts. LNG-IUS seems to be an effective, safe, and long term treatment for endometriosis with fewer side effects and better compliance.

Objective To investigate the prognostic value of △SUV and Deauville 5-point scoring (5-PS) in patients with DLBCL.Methods Thirty-nine patients (20 males,19 females;median 58 (23-85) years) with pathologically confirmed DLBCL were retrospectively analyzed from January 2009 to April 2015.PET/CT imaging was performed before and after 4 courses of chemotherapy.The optimum cutoff values of △SUVmax and its decline proportion (△SUVmax％) were calculated by ROC curve,and then the Kaplan-Meier analysis and Cox regression analysis were performed in patients with different △SUVmax and △SUVmax％.Patients were also evaluated by the observers using Deauville 5-PS,Kaplan-Meier analysis and Cox regression analysis were performed in patients with scores ≥ 4 and those with scores ＜ 4.x2 test and Spearman correlation analysis were used.Results (1) There were 10 patients (25.64％,10/39) with progressed disease within the 2 year-follow-up.The △SUVmax,△SUVmax％ of progressed group were markedly lower than those of non-progressed group:9.55± 11.90 vs 15.61±7.86,71.66％ (33.90％-78.91％) vs 87.83％(76.51％-92.43％);t=-2.37,z=-3.25,both P＜0.05.(2)The optimum cutoff values of the △SUVmax,△SUVmax％ were 11.2 and 72.88％ respectively.(3) The patients with △SUVmax ＜ 11.2,△SUVmax％ ＜72.88％ or Deauville 5-PS≥4 showed shorter PFS and △SUVmax％ was proved to be an independent prognostic factor(x2 =5.734,14.821,5.851,all P＜0.05).(4) △SUVmax％ and Deauville 5-PS were correlated (rs =-0.633,P＜0.001).Conclusions △SUV and Deauville 5-PS could be used for prognosis prediction in DLBCL patients and △SUVmax％ might be an independent predictive factor.The values of △SUVmax ％ and Deauville present a negative relationship.

Objective:To investigate the clinical and molecular genetic characteristics of 6q24-related transient neonatal diabetes mellitus (6q24-TNDM).Methods:The clinical data of two neonates with 6q24-TNDM admitted to Shanghai Children's Hospital, Shanghai Jiao Tong University in 2017, were retrospectively collected. The methylation levels of 16 cytidine-phosphate-guanosine (CpG) sites from the methylated differentially modified region (DMR) in 6q24 were quantitatively analyzed by pyrosequencing.Results:Case 1, aged 5 d, was born at 37 +4 gestational weeks due to fetal growth restriction, and case 2 was 11-days old and born at 38 +2 gestational weeks. Both infants were male and small for age. They were born through a cesarean section. The birth weight of case 1 and case 2 were 2 340 g and 2 600 g, respectively. They were admitted due to hyperglycemia with blood glucose of 12.95 and 8.00 mmol/L on admission, respectively. Physical examination showed slightly poor skin elasticity and thin subcutaneous fat. Laboratory examination revealed lower serum insulin (<1.39 and 3.94 pmol/L) and peptide C (0.05 and 0.14 nmol/L) levels, positive results of urine glucose, negative tests for urine ketone, serum anti-glutamic acid decarboxylase antibody, anti-insulin antibody, and islet cell antibody in both cases. Normal size of the pancreas was observed by ultrasonography. The infants were improved and were discharged after subcutaneous insulin infusion for more than two weeks. The treatment was discontinued at 69 d and 42 d postnatally for case 1 and case 2. Prenatal diagnosis of the two infants showed normal karyotypes and uniparental disomy of chromosome 6 indicated by single nucleotide polymorphism chip. No pathogenic mutations were detected by next-generation sequencing after admission. The methylation levels of 16 CpG sites in DMR of 6q24 in the two cases, which were quantitatively analyzed by pyrosequencing, were lower than 10% (normal value in healthy matched controls: 40%), indicating an obvious hypomethylation. Conclusions:For children with TNDM who are small for gestational age at birth, presenting hyperglycemia with decreased serum insulin and C-peptide levels, pyrosequencing can be used to quantitatively analyze the methylation levels of CpG sites in 6q24 DMR, which can quickly and directly assist in the diagnosis of 6q24-TNDM, thereby contributing to the treatment and prognosis assessment.

Objective:To investigate the clinical manifestations, imaging features, histopathological features, diagnostic pitfalls, treatment and prognosis of clear cell chondrosarcoma (CCCS).Methods:23 cases of CCCS admitted and operated from January 2010 to January 2020 were analyzed retrospectively. Among the 23 cases, 21 were males and 2 were females. There were 8 cases (35%) aged 21-40, 10 cases (43%) aged 41-60 and 5 cases (23%) aged 61-80. There were 8 femurs, 7 pelvis, 4 thoracolumbar spine, 3 sacrum and 1 tibia. The specimens were fixed with 10% phosphate-buffered formalin, decalcified with 5% nitric acid, embedded in paraffin and stained with hematoxylin and eosin (HE) and immunohistochemistry (Envision). The preoperative imaging and clinical symptoms, and the postoperative histopathological and immunophenotype under the microscope were collected. And the relevant literature was reviewed to summarize the clinical, imaging and pathomorphological characteristics of CCCS.Results:23 cases of CCCS showed bone destruction in imaging, some cases were well-circumscribed lytic lesions, some cases had sclerotic margin. The serum alkaline phosphatase was increased in 7 patients before operation. The tumor tissue was gray-white and gray-red in general and some cases showed porcelain white cartilage-like areas. Microscopically, the tumor cells are round or polygonal, some of them have clear cytoplasm and boundary, some of them are eosinophilic, some of them have round and centrally located nuclei, and mitotic image is rare. It is often seen that there are nodular distribution of cartilage-like matrix and immature woven bone, multinucleated osteoclast-like giant cell scattered in those components. Immunohistochemical staining: S-100, D2-40, EMA, Vimentin, p16, SATB2 can be positive in varying degrees. The surgical treatment is mainly through en bloc excision. 10 patients had recurrence and no distant metastasis.Conclusion:CCCS is a rare subtype of chondrosarcoma, which has low-grade malignant biological behavior and is easy to be misdiagnosed clinically and pathologically. Pathological diagnosis needs to be careful. Careful observation of microscopic histology is necessary in order to avoid over-diagnosis of osteosarcoma leading to clinical treatment errors. Once the biopsy is confirmed, it needs en bloc excision in order to reduce the recurrence rate. Long-term follow-up is needed after the operation, the overall prognosis was good.

Objective To compare the efficacy and safety of tranexamic acid(TA)and norethisterone(NET)for the treatment of patients with ovulatory menorrhagia in China. Methods Onehundred and thirty one patients with proven ovulatory menorrhagia from gynecologic clinics of 5 teaching hospitals located in 4 different cities in China were enrolled during Jul 2004 to Dec 2006.Ameng them 128 completed the study.Patients were randomly divided into two therapeutic regimen groups:TA 1g thrice daily during menstrual cycle days(D)1-5,69 cases;or NET 5 mg twice daily on D19-26.59 cases.The drugs were administered for 2 consecutive cycles,then withdrawn and patients were followed-up for 1 more cycle.Data on menstrual blood loss [ estimated by pictorial blood assessment chart(PBAC)],length of menstrual periods,quality of life(QOL)evaluated by a 6 item health-related questionnaire were collectedbefore,during each cycle and were compared.Results Both treatments led to significant decreases of mean PBAC scores and shorter duration of menstrual periods,and improved the QOL ranking during the twotreatment cycles.The mean percentages of PBAC decrements in the TA first and second cycles were significantly greater than those in the NET corresponding cycles(35%VS 17%,P=0.004;4J4%VS 34%,P=0.04 respectively).The success rate of TA second cycle was higher than that of the NET second cycle (41%VS 24%,P=0.04).Improvement of QOL ranking in the TA first cycle was also significantly better than those in the NET first cycle ( P=0.03).The percentage of patients with at least 1 adverse event in TA group(19%)was significantly lower than that in NET group(35%,P=0.04).Patients'willingness tocontinue the treatment in the TA second and follow-up cycles(94%,79%respectively)were significantly higher than those in the corresponding cycles of NET groups(79%,59%respectively;P=0.01,P=0.02).Conclusion The regimen of TA 3 g daily during menstrual days 1-5 is a more effective and tolerable treatment than luteal phase norethisterone for patients with ovulatory menorrhagia.

The purpose of this study was to observe whether human peripheral dervied monouncleas cells (hMNCs) could participate in the regeneration process of the ischemic hearts in the way of differentiating into cardiomyocytes, vascular endothelial cells and smooth muscle cells. hMNCs were transplanted into the bodies of the mice with myocardial infarction through the tail vein injection. Hearts were harvested 2-12 weeks after injection then sliced up into frozen sections of 5 micron thickness. Double immunofluorescence staining was used to test the differentiation of the grafted cells into cardiomyocytes, smooth muscle cells and vascular endothelial cells which revealed that cells expressing both HLA and TNT, HLA and alpha-SMA, HLA and vWF existed in the hearts of the mice. According to the study, it is probable that hMNCs could participate in the regeneration process of the infarcted hearts in the way of differentiation.
