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.

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.

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.

OBJECTIVEActivation of hTERT, the human telomerase catalytic subunit, has been implicated as the critical event in triggering telomerase activity of cancer cells. In present research, we investigated whether RNA interference (RNAi) induced by small interference RNA (siRNA) could suppress human telomerase catalytic unit (hTERT) gene expression in gastric SGC7901 cells.
METHODSAs a pilot study, we utilized green fluorescent protein (GFP) plasmid pCX-GFP (5 510 bp) as a reporter system and generated constructs SHi-pU6-GFP expressing small hairpin RNA (shRNA) specific for green fluorescence protein (GFP) in K562 and SGC7901 cell respectively. Furthermore, we constructed pU6-hTERT-siRNAs carried hairpin siRNA for hTERT gene and transfected in SGC7901 by using Lipofectamine trade mark 2000. The expression of hTERT gene was detected by reverse transcription polymerase chain reaction (RT-PCR) and fluorescence quantitative polymerase chain reaction (FQ-PCR) assay.
RESULTSOur pilot study showed the short hairpin RNA (shRNA) expression vector driven by the murine U6 small nuclear RNA promoter can specifically induce potent gene knockdown effect (i.e., inhibit GFP expression specifically) when transfected transiently into SGC7901 cell. The constructed pU6-hTERT-siRNAs carried hairpin siRNA for hTERT gene was proved to be the same as designed by restriction endonuclease analysis. pU6-hTERT-siRNAs were successfully transferred into SGC7901 cell and their stable expression were obtained. The expression of hTERT gene were specific inhibited by pU6-hTERT-siRNAs in SGC7901 cell.
CONCLUSIONSShort hairpin RNAs (shRNAs) could induce sequence-specific hTERT gene silencing in SGC7901 cell. Our results prove the feasibility of the U6 promoter-driven shRNA expression technique to be used to cancer gene therapy.

Objective To evaluate the technique and efficacy of retroperitoneal laparoscopic partial nephrectomy. Methods From June 2002 to December 2009, 113 cases of renal tumor received retroperitoneal laparoscopic partial nephrectomy. The age ranged from 26 to 73 years. The tumor located in left side in 51 cases and right side in 62 cases with the mean diameter of 3.7 cm(1.2-6.3cm). During the procedure, the renal artery was separated and then clamped with bulldog. The renal parenchymal was incised with cold endoscissor and the tumor was totally removed. Pelvicalyceal repairing and parenchymal hemostasis were then performed. Renal defect closure was achieved with running suture or horizontal mattress suture. Results All the procedures were completed successfully.There was no open conversion. The mean operation time was 85 min(60- 125 min), the mean warm ischemic time was 24 min(19-43 min). The pathology studies revealed 87 cases of clear cell carcinoma, 9 cases of papillary renal cell carcinoma, 7 cases of chromophobe cell carcinoma, 6 cases of perivascular epithelioid renal cell tumor and 4 cases of renal oncocytoma. The surgical margin was negative in all cases. There was no complication of urine leakage. Gross hematuria occurred in 2 cases.During 3-41 months of following up, there was no recurrence. Conclusion Retroperitoneal laparo-scopic partial nephrectomy is safe and effective for the treatment of renal tumor, which becomes an alternative treatment to open procedure.
