Objective To study the clinical significance of antinuclear antibody (ANA),anti-thyroid peroxidase antibody (TPO-Ab) and antithyroglobulin antibody (Tg-Ab),thyroid stimulating hormone (TSH),free triiodothyronine (FT3),free thyroxine (FT4) in patients with recurrent spontaneous abortion (RSA).Methods 46 women with RSA diagnosis in out patient department in Peking University Shenzhen Hospital from March 2015 to December 2016 were recruited as the study group,20 women with normal childbirth history were enrolled as the control group,ANA was detected by indirect immunofluorescence (IIF) assay and ELISA,TSH,FT3 and FT4 were detected by chemiluminescence immunoassay technology.Results The positive rates of ANA(IIF),TPO-Ab and Tg-Ab in patients with RSA were 24％,24％ and 15％ respectively which were significantly higher than those in healthy control (P＜0.05).Serum levels of TSH,TPO-Ab and Tg-Ab in patients with RSA were 2.70 ± 1.38 mIU/L,38.99 ± 10.18 IU/ml and 3.07 ± 1.69 IU/ml respectively,which were significantly higher than those in healthy cases (P＜0.05).Conclusion ANA and antithyroid antibodies were closely related with RSA.It is very important to screen ANA and antithyroid antibodies for etiological diagnosis and appropriate intervention in patients with RSA to reduce the incidence of abortion.

Nitrites play multiple characteristic functions in invasion and metastasis of hepatic cancer cells, but the exact mechanism is not yet known. Cancer cells can maintain the malignant characteristics via clearance of excess mitochondria by mitophagy. The purpose of this article was to determine the roles of nitrite, reactive oxygen species (ROS) and hypoxia inducing factor 1 alpha (HIF-1 α) in mitophagy of hepatic cancer cells. After exposure of human hepatocellular carcinoma SMMC-7721 cells to a serial concentrations of sodium nitrite for 24 h under normal oxygen, the maximal cell vitality was increased by 16 mg x (-1) sodium nitrite. In addition, the potentials of migration and invasion for SMMC-7721 cells were increased significantly at the same time. Furthermore, sodium nitrite exposure displayed an increase of stress fibers, lamellipodum and perinuclear mitochondrial distribution by cell staining with Actin-Tracker Green and Mito-Tracker Red, which was reversed by N-acetylcysteine (NAC, a reactive oxygen scavenger). DCFH-DA staining with fluorescent microscopy showed that the intracellular level of ROS concentration was increased by the sodium nitrite treatment. LC3 immunostaining and Western blot results showed that sodium nitrite enhanced cell autophagy flux. Under the transmission electron microscopy (TEM), more autolysosomes formed after sodium nitrite treatment and NAC could prevent autophagosome degradation. RT-PCR results indicated that the expression levels of COX I and COXIV mRNA were decreased significantly after sodium nitrite treatment. Meanwhile, laser scanning confocal microscopy showed that sodium nitrite significantly reduced mitochondrial mass detected by Mito-Tracker Green staining. The expression levels of HIF-1α, Beclin-1 and Bnip3 (mitophagy marker molecular) increased remarkably after sodium nitrite treatment, which were reversed by NAC. Our results demonstrated that sodium nitrite (16 mg x L(-1)) increased the potentials of invasion and migration of hepatic cancer SMMC-7721 cells through induction of ROS and HIF-1α mediated mitophagy.

The aim of this study was to investigate the expression of wt1 gene and the changes of gene expression in minimal residual disease (MRD) models (K562, HL-60 cell lines) and acute leukemia (AL) patients through inhibiting the expression of wt1 gene by antisense oligonucleotides (ASO). The bone marrow (BM) of 56 AL patients with complete remission (CR) was collected, then the BM samples with positive expression of wt1 gene were screened by RT-PCR. The cells of MRD model and screened wt1 gene positive samples were cultured and treated by ASO, then the changes of wt1 gene expression were detected. The results indicated that the sensitivity of wt1 gene was 10(-3)-10(-4), and the positive rate of BM wt1 gene expression in 56 AL patients with CR was 16%. After BM of 9 AL CR patients with MRD and MRD model (K562, HL-60 cells) expressing wt1 gene were treated by ASO, it was found that the wt1 expression in ASO group was blocked, while wt1 gene could be still detected in both sense oligonucleotides (SO) and control groups. It is concluded that ASO can obstruct the expression of wt1 gene on the residual leukemia cells in vitro.

To study the anti-coagulant effect and influence of danggui Sini decoction (DSD) on rat's plasma endogenous metabolites by animal experiment and ¹H-NMR based metabolomics method. After intragastric administration of Danggui Sini Decoction for 7 days, Plasma thrombin time (TT) was measured. Rat plasma metabolic fingerprint in two groups was analyzed using ¹H-NMR, based on which the principal component analysis( PCA) and orthogonal partial least-squares discriminant analysis(OPLS-DA) models for metabonomic analysis. Potential biomarkers were screened by using variable importance in the projection (VIP) and T test. DSD could prolong TT of the rat significantly (P < 0.05). Compared with control group, six kinds of endogenous metabolites in DSD group change significantly (P < 0.05), among which isobutyrate, carnitine and phenylalanine content had an upward trend (P < 0.01) and lysine, Histidine and cholesterol content had a downward trend (P < 0.05). It is likely that carnitine, phenylalanine, Histidine and cholesterol are the potential metabolic markers in the anti-coagulant process and DSD affects the platelet aggregation and the expression of tissue factor and fiber protease by regulating the energy, amino acid and lipid metabolism.

OBJECTIVETo study the surgical reconstruction of secondary fracture deformities of the nasal-orbital ethmoid area.

METHODSTypical bicoronal and subciliary incisions or the adjacent scar incision were employed to expose the fractured area. The flattened nasal bone was narrowed by curved osteotomy along the medial orbital rims and trimed with a bur. 2-3 pieces of cranial outer table were used to reconstruct the nasal framework, which were fixed to the frontal bone with mini-plates. After the medial orbital wall and orbital floor were exposed, the herniated orbital contents were released and reduced to the orbital cavity. The fractured orbital walls were repaired precisely with autogenous cranial outer table or Medpor. The medial canthal tendons were anchored superior-posteriorly to the lacrimal fossa with transnasal wires.

RESULTSFrom December 1996 to December 2001, 34 cases of severe nasal-orbital ethmoid fracture deformities were repaired with this technique. Of them, 12 cases had combined orbital-zygomatic fracture, 4 cases had fontal sinus fracture, 1 case had Le Fort II and 1 case had Le Fort III fracture. All the patients recovered well and their facial appearance improved greatly.

CONCLUSIONSThe key points for surgical reconstruction of the periorbital post-fracture deformities are narrowing the flattened nasal root by curved osteotomy, the nasal framework reconstruction with autogenous bone graft, the orbital wall repair to correct enophthalmos, and most importantly, the medial canthal tendon reduction and canthal plasty.
