Objective To improve the understanding,the incidence and imaging findings of tuberous sclerosis complex (TSC) combined with cardiac rhabdomyomas (CRs) in fetuses and infants.Methods The imaging findings of 9 infants with TSC combined with CRs and 4 fetuses with TSC combined with CRs from our hospital between June,2006 and November,2013 were retrospectively reviewed.Results The brain MRI of 9 with TSC combined with CRs showed bilateral subependy-mal nodules,subcortical white matter and cortical tubers.Subependymal nodules were isointense or hypointense on spin-echo T1WI and hypointense or hyperintense on spin-echo T2WI.Subcortical white matter and cortical tubers were hypointense or hyperintense on T1WI and hypointense or hyperintense on T2WI.There was varying contrast enhancement.Three of 9 infants presented single cardiac tumor and 6 of 9 infants presented multiply cardiac lesions.CRs on contrast cardiac MRI showed round solid masses in ventricular septums,ventricular outflow tract,ventricle or atrial free walls.The masses were isointense relative to the cardiac muscles on T1WI,T2WI and B-TFE sequence.There was varying contrast enhancement.Four fetuses with TSC on ultrafast MRI showed bilateral multiply subependymal nodules,the nodules were isointense or hyperintense on TFE T1WI and isointense or hypointense signals on SSTSE or B-FFE sequence,Four fetuses with CRs showed isointense to hyperintense solid masses in ventricular septums on ultrafast MRI,ventricle or atrial free walls on B-FFE sequence and SSTSE sequence images.Conclusions TSC in infant and fetus is a kind of neurocutaneous syndrome,usually combines with CRs.Fetal ultrafast and routine MRI is a useful method to make a definite diagnosis for cranial and cardiac lesions.The development of MRI might improve the timeliness and accuracy of the assessment for this disease.

Objective To evaluate the safety of surgical procedures for patients after heart valve prosthesis implantation.Methods Clinical data of 12 cases with heart valve prosthesis implantation undergone other surgical treatment from November 1996 to December 2005 were retrospectively analyzed.All the cases had routine oral warfarin with prothrombin time (PT) of 20.0—28.3 s averaged 23.5 s, international normalized ratio (INR) for prothrombin of 1.79—2.23 averaged 1.95 and heart functional class Ⅰ—Ⅲ.Among them,appendectomy was performed in three cases with acute appendicitis,reposition and repair in one with inguinal hernia,radical gastrectomy in two with gastric carcinoma,left hemicolectomy in one,cholecystectomy in three,left femoral head replacement in one,and bilateral high ligation and ablation of great saphenous vein in one.Elective surgical operation was performed in seven cases,and emergency operation in five.In those with elective surgery,warfarin was stopped 2—3 days before operation,while 5—10 mg vitamin K_1 was injected intramuscularly 6—8 hours before emergency surgery with preoperative median PT of 15.1 and 15.3 s and median INR of 1.24 and 1.30,respectively.In operation,5—10 mg vitamin K_1 were injected intravenously into the patients by drip depending on their bleeding on the surface of wound.ECG,blood pressure,hemoglobin and oxygen saturation were routinely monitored for all the cases intraoperatively and postoperatively.For the cases with heart function above class Ⅱ,fluid infusion was adjusted based on intubated central venous pressure,and for those with general anesthesia,analyses of blood gases and electrolyte were monitored routinely in operation.Results OPeration time averaged 20—160 rain in all the 12 patients,with blood loss 5—280 ml in average and without complications of massive hemorrhage,thrombosis and heart failure.Conclusions Surgical operation was safe for patients with heart valve prosthesis implantation,if preoperative PT and INR were adjusted to about 15 s and 1.30,respectively by cessation of warfarin or application of vitamin K_1,combined with careful manipulation and strengthened perioperative management.

Objective To investigate the clinical significance of tumor related gene gankyrin expression in pancreatic cancer.Methods The immunohistochemical staining was performed to study the gankyrin expression in 62 pairs of pancreatic cancer and matched non-tumor tissues.The correlations ofgankyrin expression with pathological parameters and the influences on the prognosis were analyzed.Results Ggankyrin positivity in pancreatic cancer and matched non tumor tissue was 2.5％ (45/62)and 19.4％ (12/62),respectively.The positivity of gankyrin was significantly higher in pancreatic cancer compared with matched non-tumor tissues,and the differences were statistical significant (P ＜ 0.01).Gankyrin expression in pancreatic cancer tissues were significantly correlated with TNM stage,differentiation and metastasis (P ＜ 0.05),but not with age,gender or tumor location (P ＞ 0.05).The 3-year survival rates of patients with positive and negative gankyrin expression were 17.8 ％ (8/45)and 41.2％ (7/17),respectively.Patients with positive gankyrin expression had a significantly shorter survival period compared with these with negative expression in pancreatic cancer tissues (P =0.034).Conclusions Gankyrin was overexpressed in pancreatic cancer,which was correlated with poor prognosis.

BACKGROUND: The study aimed to estimate the value of embryonal natural orifice transluminal endoscopic surgery (ENOTES) in treating severe acute pancreatitis (SAP) complicated with abdominal compartment syndrome (ACS). METHODS: The patients, who were randomized into an ENOTES group and an operative group, underwent ENOTES and laparotomy, respectively. The results and complications of the two groups were compared. RESULTS: Enterocinesia was observed earlier in the ENOTES group than in the operative group. Acute Physiology and Chronic Health Evaluation II (APACHE II) score of patients in the ENOTES group was lower than that of the operative group on the 1st, 3rd and 5th post-operative day (P<0.05). The cure rate was 96.87％ in the ENOTES group, which was statistically different from 78.12％ in the operative group (P<0.05). There were significant differences in complications and mortality between the two groups (P<0.01). CONCLUSION: Compared with surgical decompression, ENOTES associated with flexible endoscope therapy is an effective and minimal invasive procedure with less complications.

Objective To improve the awareness of the CT and/or MRI appearances and clinical presentations of Kasabach-Merritt syndrome(KMS),6 cases were reported.Methods The CT and/or MRI and clinical characters of 6 cases of KMS were reviewed and analyzed.Results Thrombocytopenia,and consumption coagulopathy were presented in all 6 cases.The paravertebral mass of posterior mediastinum, right pericardial lesion,skin and soft tissue of left arm were shown as iso-,hypointensity on T1-weighted image,iso-,hyper-intensity on T_2-weighted image,and with heterogeneous enhancement after contrast administration in three cases.Splenomegaly was presented in one case,it showed homogenous hypoattenuation on unenhanced CT,and diffused heterogeneous enhancement after contrast administration. On MRI,spleen was shown as hypointensity on T_1-weighted image,hyperintensity on T_2-weighted image, and with heterogeneous enhancement after contrast administration.There were lesions in both bones and spleen in one case.Osteopenia and thinned cortex were shown on the metaphyses of upper and lower extremities.Spleen enlarged and showed multifocal hypoattenuation lesions,the peripheral region enhanced on the early phase,and some of the lesions filled on the delayed phase after the contrast administration.One case showed huge hypoattenuation lesion in the left lobe of liver with gradually filling of the mass after peripheral enhancement.Conclusion Thrombocytopenia and consumption coagulopathy suggest the entity of extensive hemangioma.Splenomegaly with diffuse or focal hypoattenation or hypointensity in MRI infers the diagnosis of hemangioma.

Objective To observe the effect of atorvastatin on mixed dyslipidemia in type 2 diabetic patients. Methods 39 patients of type 2 diabetic with mixed dyslipidemia were taken with atorvastatin for 6 months,and the change of total cholesterel(TC),triglyceride(TG),low-debsity-lipoprotein-cholesteral(LDL-C),high-debsity-lipopro- tein-cholesteral(HDL-C)were observed.The incidence of side-effect was recorded.Results TC,TG,LDL-C were obviously reduced and their extent of reduction were 26.17 %,54.97 %,38.92 %.HDL-C was obviously increased and it's extent of increase was 14.81%(P

OBJECTIVETo identify the genetic alterations in nonsyndromic cleft lip and palate (NSCLP).

METHODSComparative genomic hybridization was applied to investigate the genomic imbalance (the gain or loss of genetic material) in 7 cases of NSCLP.

RESULTSIt showed that the loss of chromosome DNA copies happened in chromosome 6, 7, 10, 13, 14, 16, 20, 22 and the gain of chromosome DNA copies happened in chromosome 5, 15, 18, 19. Conclusions 13q had a high frequency (71.4%) of chromosome loss.

CONCLUSIONSAbnormal chromosome DNA copies happen in all the patients with NSCLP. Most of the patients have chromosome DNA copies loss. It suggests that loss of inhibitory gene may be related to the NSCLP. The related inhibitory gene may locate in 13q.
