Hyperuricemia and metabolic syndrome were studied in 17 762 subjects of Tianjin Municipality from July 2007 to July 2009. The overall prevalence rate of hyperuricemia was 12. 16% (2160cases) , the rate in males was significantly higher than that in females (15. 71% vs. 6. 51% , P <0. 01).The overall prevalence rate of metabolic syndrome was 25. 56% (4540 cases) , the rate in males was also higher than that in females (28. 17% vs. 21. 40% , P <0. 01). Binary logistic regression analysis disclosed that females with high uric acid were twice likely to suffer from metabolic syndrome than males; and female ≤ 44 years with hyperuricemia had the highest odd ratio for metabolic syndrome.

Objective To investigate the safety,effectiveness and prognosis of percutaneous microwave ablation (MWA) combined with synchronous transarterial chemoembolization (TACE) to treat of gastroenteropancreatic neuroendocrine neoplasms (GEP-NENs) with liver metastases (LMs).Methods This retrospective study included 19 cases of GEP-NENs with LMs patients who received percutaneous MWA combined with synchronous TACE treatment from 2013 to 2016.The mRECIST standard was selected to assess the curative effect.SPSS 21.0 software was applied in the statistical analysis of overall survival (OS),progression-free survival (PFS) and factors related to prognosis.Results All patients were capable of curative effect evaluation,including 1 case of complete remission (CR),3 cases of partial remission (PR),7 cases of progressive disease (PD) and 8 cases of stable disease (SD) respectively accounting for 5 ％,16 ％,37 ％,42 ％,which exhibited 21％ of response rate (RR) and 63％ disease control rate (DCR).In the present study,the median OS and median PFS was respectively 25 months and 34 months,and the one-year survival and three-year survival was respectively 95％ and 84％.Serum CA199,the WHO classification of LMs and the tumor burden of LMs were the major risk factors of prognosis through single factor analysis of survival,which showed that G3 of the WHO classification of LMs predicted a poor OS (P＜0.05) and tumor burden of LMs was negatively related to PFS (P＜0.05).It was obviously observed that serum CgA was decreased by the therapy of percutaneous MWA with synchronous TACEfor GEP-NENs (P＜0.05).Conclusions Percutaneous MWA combined with synchronous TACE is a safe and effective method to treat GEP-NENs with LMs.

Objective To investigate the prenatal diagnosis and postnatal clinical outcomes of fetal congenital choledochal cyst (CCC) to improve the recognition and treatment of fetal CCC.Methods Clinical data of 23 cases of fetal CCC which were diagnosed during routine prenatal ultrasonic examination in Jinhua Municipal Central Hospital from June 2009 to May 2015 were retrospectively analyzzed. Maternal age, gestational age at diagnosis of CCC, location and size of cyst, postnatal examination, age at operation and follow-up outcomes were recorded and statistically analyzed by Wilcoxon rank-sum test.Results (1) Among the 23 cases, six (26%) were terminated and the rest 17 continued their pregnancies (74%). (2) Results of the prenatal ultrasonography of the 23 cases indicated that hepatic portal cysts were closely related to hepatic portal veins or arteries. Six of the cysts communicated with gall bladder and eight connected to intrahepatic bile duct. The maximum diameter of the cysts in the 23 cases was 16.0-31.0 mm, averagely (24.7±3.7) mm. The maximum diameter of cysts diagnosed in the third trimester was significantly larger than that in the second trimester [ 27.0 (22.0-31.0) vs 23.0 (21.0-25.0) mm,Z=-2.134,P<0.05]. (3) Among the 17 cases of continued pregnancy, one underwent cesarean section at 35+ weeks of gestation and 16 delivered at term with the average gestational age at delivery of (38.2±1.1) weeks. All neonates were re-examined by abdominal ultrasound at 1-2 postnatal weeks and confimed prenatal diagnosed of CCC. (4) The 17 neonates were re-examined by abdominal ultrasound during the second postnatal week and the results showed that cyst size remained the same in four, decreased in one and gradually increased with the gestational age in 12 neonates. Among the 16 cases of confirmed CCC, 12 received surgery, including 11 (Ⅰa, 6;Ⅰc, 3;Ⅳb, 2) within one year-old and one (Ⅰc) around 18 months old. The prognosis was uneventful. Four out of the 16 cases rejected surgical operation and were followed up in outpatient. One neonate was diagnosed with congenital biliary atresia and transferred to Children's Hospital for operation.Conclusions When fetal abdominal cyst presented with hepatic portal cyst which communicates with gallbladder or intra-hepatic duct in ultrasonography, a congenital choledochal cyst should be taken into consideration by excluding the possibility of biliary atresia in the first place. Surgery for CCC infants without symptoms or signs is suggested to be performed around three months after birth. The postoperative prognosis of CCC is favorable, so termination is not recommended for gravidas with fetal CCC in prenatal consultation.

Based on the experience of Public-Private Partnership (PPPs) model in domestic and foreign medical field, this study innovatively explored and designed the Build-Transfer-Operate-Transfer (BTOT) operational structure taking the second phase project of ZP Hospital in Pudong New District as a case study.The exploration results showed that the model established the social capital of private non-profit medical institutions by setting up the project company, and used the asset rental and operating management fees in the form of return path.In view of this, the study put forward some relevant countermeasures and suggestions from the aspects of the institution nature and national treatment, property right ownership and risk mitigation, balancing of interests and the cooperation period and solving the core staff etc.All of these measures were taken in order to explore the replicable PPP model in the field of public hospital reform and development.

Objective:To screen the time points of high survival rate and efferocytosis dysfunction of rat alveolar macrophages stimulated by cigarette smoke extract (CSE), establish an in vitro model of alveolar macrophage efferocytosis function, and study chronic respiratory diseases with chronic inflammatory reaction as the main pathological changes. Methods:① Time point screening experiment: rat alveolar macrophages (NR8383 cells) were cultured in vitro, and the cells in logarithmic growth phase were divided into blank control group (100 μL complete medium) and 5% CSE group (90 μL complete medium + 10 μL 100% CSE). Alma blue method was used to detect the effect of 5% CSE on the activity of NR8383 cells at 6, 12, 24 and 48 hours. ② Apoptosis induction experiment: rat type Ⅱ alveolar epithelial cells (RLE-6TN cells) were cultured in vitro as phagocytic target cells of NR8383 cells, and the cells in logarithmic growth phase were divided into blank control group and 10, 30 and 60 minutes groups after ultraviolet exposure (apoptosis was induced by 30 000 μJ/cm 2 ultraviolet irradiation for 15 minutes). Flow cytometry was used to detect the apoptosis rate of RLE-6TN cells cultured for 10, 30 and 60 minutes after ultraviolet exposure. ③ Cell efferocytosis experiment: NR8383 cells in logarithmic phase were divided into blank control group and 5% CSE group. Two hours before NR8383 cells were stimulated by CSE for 6, 12 and 24 hours, RLE-6TN cells were exposed to ultraviolet to induce apoptosis, and the RLE-6TN cell suspension was added to NR8383 cells (the ratio of RLE-6TN cells to NR8383 cells was 5∶1). Flow cytometry was used to detect the efferocytosis rate of NR8383 cells to RLE-6TN cells at different time points treated with 5% CSE. Results:① Compared with the blank control group, the activity of NR8383 cells significantly decreased after treatment with 5% CSE for 48 hours [cell reduction rate: (68.5±4.1)% vs. (73.6±2.3)%, P < 0.05]. However, there were no significant differences when the activities of NR8383 cells treated with 5% CSE for 6, 12 and 24 hours were compared with the blank control group, so these three time points were selected for the subsequent establishment of alveolar macrophage cell efferocytosis dysfunction in vitro model experiment. ② Compared with the blank control group, the apoptosis rate of RLE-6TN cells significantly increased at 10, 30 and 60 minutes after ultraviolet exposure [(66.87±8.63)%, (85.51±2.39)%, (96.13±2.74)% vs. (9.13±3.17)%, all P < 0.01] in a time-dependent manner. Considering that it taked about 50 minutes for RLE-6TN cells to be labeled with PKH26 membrane labeling probe, 10 minutes after ultraviolet exposure was selected to label RLE-6TN cells. ③ Compared with the blank control group, the efferocytosis function of NR8383 cells was significantly decreased after treatment with 5% CSE for 12 hours [cell efferocytosis rate: (33.64±1.30)% vs. (44.02±2.71)%, P < 0.01], but there was no significant effect on the efferocytosis function of NR8383 cells at 6 hours and 24 hours. Conclusions:CSE can induce alveolar macrophage cell efferocytosis dysfunction. Based on the test results of the effect of 5% CSE on NR8383 cell activity and cell efferocytosis function, 12 hours with high survival rate and weak efferocytosis effect of NR8383 cells can be selected as the in vitro model condition of alveolar macrophage cell efferocytosis dysfunction.

Objective To investigate the effects of human amniotic membrane on the survival of the crossboundary perforator flap in rats through distal subcutaneous implantation.Methods From February,2016 to December,2016,38 SD rats weighing 270-300 g were randomly divided into experimental group and control group (n=19).A three-territory perforator flap (3 cm× 10 cm) with the iliac artery as the pedicel elevated on the right dorsum of the rats.Experiment group,a section of amnion was sutured to the distal subcutaneous of the flap and then the flap was sutured back to its donor site.Control group,after the flap elevated,directly sutured back to its donor site.The blood flow of the pedicel were detected by laser Doppler flowmetry at the day before surgery,1 day after surgery,3 and 7 days after surgery,with 3 rats in every group.When the rats were anesthetized,biopsies were taken from the choke area Ⅱ at the day before surgery,3 and 7 days after surgery,with 9 rats in every group.When the rats were anesthetized,HE was used to compare the diameter size of the artery and vein at the same site.At day 7,measure the survival area of the flap,and 3 of them observe the vessel of the flap by lead oxide-gelatine technique.Results The survival rate of the experimental group and the control group after 7 days were (89.09±4.23)％ and (74.56-±5.59)％ respectively,the experimental group was significantly higher than that of the control group (t=5.48,P=0.00).X-ray showed that 7 days after operation,the pedicel of iliac artery in the experimental group was bigger than that in the control group.The blood flow detection showed that the blood flow of the experimental group was higher than that of the control group (t=2.39,3.06;P=0.03,0.00,respectively) at day 1 and day 3 after surgery.Hematoxylin eosin staining showed that arteriovenous tube diameter at the Choke Ⅱ were gradually increased on the day3 and day7 after surgery in both group,but the experimental group diameter expanded multiple was higher than that of control group (t=3.52,3.50;P=0.02,0.02,respectively).Conclusion Human Amnion subcutaneous embedding may improve the blood flow of the vascular pedicle,expand the microvascular at Choke area Ⅱ,improve microcirculation,as a result to promote the survival of cross perforator flap,while the mechanism is needed to understanding.

OBJECTIVETo use next generation sequencing (NGS) to identify unknown abnormality of chromosome 9 in a fetus and explore its mechanism.

METHODSA pregnant woman with abnormal fetal ultrasound finding underwent amniocentesis for G-banded chromosomal analysis. Karyotyping was also performed on peripheral blood samples derived from its parents. Fetal blood sample was obtained for NGS testing to identify abnormality unrecognized by karyotyping.

RESULTSAnalysis of amniocytes has revealed a 46,XX,der(9)(?::p21 to qter) karyotype, while both parents had a normal karyotype. NGS analysis of the fetus revealed a 20.67 Mb duplication (4 454 279-25 126 275) at 9p21.3p24.2, which overlapped with that of the 9p duplication syndrome, and a 4.43 Mb deletion at 9p24.2p24.3 (10 001-4 442 364), which partially overlapped with that of 9p deletion syndrome and 46,XY sex reversal 4 region. Comparison of the sequencing data with reference genome database indicated direct duplication of 9p21.3p24.2, which was also supported by review of the morphology of chromosome 9p. Therefore, the karyotype of the fetus was verified to be 46,XX,der(9) dir dup(9)(p21.3p24.2), del(9)(p24.2p24.3).

CONCLUSIONCombined G-banded karyotyping and NGS can identify dir dup del(9p) with accuracy. Delineation of the mechanism of dir dup del(9p) and its genotype-phenotype correlation may facilitate genetic counseling and estimation of recurrence risk.

Objective:To observe the clinical and pathological features of choroidal malignant melanoma (CM).Methods:A retrospective case study. From 2011 to 2021, paraffin specimens from 15 eyes of 15 CM patients diagnosed by pathological examination in the Department of Pathology, the Second Affiliated Hospital of Soochow University were included in the study. The age, gender, clinical manifestations, treatment plan and pathological examination results of patients were collected retrospectively through the hospital information system. The clinical characteristics, immunohistochemical staining and molecular pathological characteristics were analyzed.Results:Among the 15 cases, 8 males and 7 females. The average age was 61. All patients were monocular paroxysm. There were 8 cases of decreased vision, blurred vision and dark shadow in front of the eyes; 1 case had red eye, lacrimation and purulent secretion; 2 cases had visual loss and no light perception; 4 cases had retinal detachment. The average diameter of the tumors was 1.4 cm. The general appearance of the tumor was hemispherical, "mushroom-shaped" or flat diffuse. Most of the tumor cells were arranged in solid, flaky and cross clusters, and some of them were arranged in false "chrysanthemum form" around the blood vessels with necrosis. In 15 eyes, spindle-cell type, epithelioid type and mixed cell type were 6, 2 and 7 eyes, respectively. The cytoplasm was partly double stained or eosinophilic, partly clear, and partly rich in pigment. The cells had poor adhesion, marked atypia, rough chromatin, frequent mitotic figures, and prominent nucleoli. Immunohistochemical staining was positive for HMB45, SOX10, S100 and Melan-A in 15 patients, but negative for epithelial markers AE1/3, lymphatic markers LCA, neuroendocrine markers CgA and Syn. Genetic testing results showed that none of the patients found C-KIT, BRAF, NRAS gene mutations. Fifteen patients were followed up for 8-96 months, of which 12 survived and 3 died after recurrence and/or metastasis.Conclusion:CM has no specific clinical clinical manifestations, and he diagnosis depends on histological morphology and immunohistochemical staining.

Objective To investigate the cytidine triphosphate synthetase 1 (CTPS1) expression in pancreatic cancer cell lines and its impaction on prognosis.Methods The GEO profiles database was searched to collect clinical data of 39 patients of pancreatic ductal adenocarcinoma.Kaplan-Meier curve was used to analyze the relationship between the patients' prognosis and the expression of CTPS1.qPCR and Western blot were applied to detect the expression of CTPS1 in 4 pancreatic cancer cell lines.Results The mRNA expression of CTPS1 in Sw1990,BxPC-3,Panc1,and MIA-Capa2 was 1.00) ± 0.20,2.92±0.95,4.29±0.14,and 2.26±0.33 (t=-16.19,-11.45,-8.09,-13.12,P＜0.05) when compared to the normal pancreatic ductal epithelial cell line HPDE of 7.70 ± 0.72.The relative protein expression of CTPS1 in pancreatic cancer cell lines Sw1990,BxPC-3,Panc1,and MIA-Capa2 was 0.40 ± 0.06,0.20±0.09,0.68±0.11,and0.48±0.06 (t=-8.97,-10.5,-4.39,-7.88,P＜0.05) when compared to HPDE of 1.09 ±0.12.The overall survival (OS) in patients with higher CTPS1 expression than adjacent tissue was 28 months (95％ CI:9.2-46.8 months),and that with lower CTPS1 expression was 13 months (95％ CI:8.2-17.8 month),(x2 =4.02,P＜0.05).Conclusions CTPS1 in the pancreatic cancer cell lines are of low expression,and the level is positively related to patients' survival time.
