Objective To investigate features of maxillary morphology in unilateral cleft lip and palate (UCLP) with maxillary retrusion and the dissimilarities of retruded maxilla.Methods Craniofacial measurements were done in 32 UCLP adult patients with maxillary retrusion (GC), 24 adult patients in class Ⅲ (GⅢ), and 32 healthy adults (GN).The CT slice data was reconstructed into a 3D video model and measured by Mimics 16.01.Results The maxillary volume (GM) and the volume composed of maxilla and maxillary sinuses (GT) were significantly smaller (P<0.05) in GC.The anterior and posterior parts of the maxillary length (A1-P3M⊥CP and P3M-P6M⊥CP) and overall maxillary length(A1-P6M⊥CP)at the dental level were all significantly reduced (P<0.05).There was no significant difference of the distances of A1⊥CP between the GC and GⅢ groups, while the P3M-CP and P6M-CP in the GⅢ group were significantly shorter (all P<0.05).The anterior and overall maxillary length at the dental level (A1-P3M⊥CP and A1-P6M⊥CP) in the GC group was significantly smaller than that in the GⅢ group (all P<0.05).Conclusions The decreased prominence of maxillary complex could be caused by the shortened maxillary length in UCLP patients;the posterior position of the maxilla is more obvious than that of GC group in class Ⅲ patients.

Objeetive To study the differences of the biological characteristics and immune regulation function of adipose mesenchymal stem cells (AMSCs)from psoriasis patients and healthy people.Methods AMSCs were isolated and cultured from human psoriatic and healthy adipose tissue,the phenotypes and cell cycle of AMSCs taken from three generation were detected by flow eytometry.Alkaline phosphate enzyme staining and oil red o staining were used respectively to identify their adipogenic and osteogenic capacity.Next,the levels of inflammation antimicrobial proinflammatory factor were detected by PCR and ELISA.Then gene expression profile of AMSCs were screen by gene expression profile chip,as so to bolting the the gene array related with immunology gene.Results There was no significant change in cell morphology,and cell surface markers were expressed high for CD29,CD44,CD73,while lower for CD31,CD45 and HLA-DR.AMSCs of psoriasis patients and healthy people both had the ability of adipogenic and osteogenic differentiation.But the cell cycle showed the third generation AMSCs proliferation rates were slower than that of normal control,as compared with healthy controls,adipogenic differentiation ability was stronger.What'more,the level of inflammatory cytokines in psoriasis group was lower than that in controls such asIL-10,IDO,TGF-β,on the contrary the levels of proinflammatory factor in psoriasis group were higher than that in controls,such as TNF-α,IFN-γ.In addition,gene chip results suggested that psoriasis group AMSCs had obvious expression differences on JAK-STAT pathway with healthy controls.Conclusions Compared with the control,there are significant differences in patients AMSCs proliferation and adipogenic differentiation ability,immune inflammation suppression control ability is weaken,this phenomenon may be associated with JAK-STAT immune pathways related to downgrade.

BACKGROUND/AIMS: Patients with long-standing diabetes often demonstrate intestinal dysfunction and abdominal pain. However, the pathophysiology of abdominal pain in diabetic patients remains elusive. The purpose of study was to determine roles of voltage-gated sodium channels in dorsal root ganglion (DRG) in colonic hypersensitivity of rats with diabetes. METHODS: Diabetic models were induced by a single intraperitoneal injection of streptozotocin (STZ; 65 mg/kg) in adult female rats, while the control rats received citrate buffer only. Behavioral responses to colorectal distention were used to determine colonic sensitivity in rats. Colon projection DRG neurons labeled with DiI were acutely dissociated for measuring excitability and sodium channel currents by whole-cell patch clamp recordings. Western blot analysis was employed to measure the expression of NaV1.7 and NaV1.8 of colon DRGs. RESULTS: STZ injection produced a significantly lower distention threshold than control rats in responding to colorectal distention. STZ injection also depolarized the resting membrane potentials, hyperpolarized action potential threshold, decreased rheobase and increased frequency of action potentials evoked by 2 and 3 times rheobase and ramp current stimulation. Furthermore, STZ injection enhanced neuronal sodium current densities of DRG neurons innervating the colon. STZ injection also led to a significant upregulation of NaV1.7 and NaV1.8 expression in colon DRGs compared with age and sex-matched control rats. CONCLUSIONS: Our results suggest that enhanced neuronal excitability following STZ injection, which may be mediated by upregulation of NaV1.7 and NaV1.8 expression in DRGs, may play an important role in colonic hypersensitivity in rats with diabetes.

Objective To investigate the internal quality control ( IQC ) on clinical chemistry , clinical immunology and clinical hematology in mutual recognition laboratories in medical institutions in Beijing.Methods By means of questionnaire survey and on -site investigation, fresh frozen serum and whole blood samples with assigned values by reference method were measured to investigate the status of IQC on clinical chemistry , clinical immunology and clinical hematology in 142 mutual recognition laboratories in medical institutions of Beijing,and results were analyzed.Results 142 copies of questionnaireson clinical chemistry, clinical immunology and clinical hematology were send out and 120, 97, and 101 laboratories returned the questionnaires respectively .The information feedback rate was 84.5%, 68.3% and 71.1%respectively .All the questionnaires were effective .Questionnaires survey results showed that more than 50%laboratories set up quality control goals and the most of the goals were probability for error detection ( Ped) 95%, probability for false rejection(Pfr)5%;About 70% laboratories usecd the same quality control plan for different tests ;The most frequently used quality control rules are 12s/13s/22s.On-site investigation showed that ,take the results of clinical chemistry for example , based on the desirable biological variation and WS/T 403 -2012 , most of the tests can't meet the quality control goalsunder the existing quality controlcondition.Conclusion Clinical laboratories should consider their actual situations , assess their own qualitylevels that they can reach , set reasonable quality standards for themselves , and make appropriateindividualized quality control plan.

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 explore the correlation of ZNF217 expression to the carcinogenesis and progression of human ovarian cancer.

METHODSImmunohistochemistry and real-time RT-PCR were used to detect ZNF217 expression in human ovarian cystadenocarcinoma, ovarian cystadenoma and normal ovary tissues.

RESULTSThe expression levels of ZNF217 protein and mRNA in ovarian cystadenocarcinoma was significantly higher than those in matched ovarian cystadenoma and normal tissues (P<0.05). No significant difference was found in the expression between ovarian cystadenoma and normal ovarian tissues (P>0.05). The mRNA expression in the specimens was consistent with the protein expression of ZNF217 (P<0.05).

CONCLUSIONZNF217 gene expression is closely correlated to the occurrence and clinical stages of ovarian carcinomas, suggesting that ZNF217 can be an important candidate gene responsible for the occurrence and progression of ovarian carcinomas.
