Objective To evaluate the dynamic MR imaging findings of peripheral cholangiocarcinoma (PCC) of the liver. Methods Seventeen patients with PCC underwent dynamic MRI during the early, middle, and delayed phase after contrast medium administration. Enhancement pattern of the tumor, the wedge-like enhancement area peripheral to the tumor, dilatation of the intrahepatic biliary ducts, vascular involvement, and extrahepatic tumor invasion were evaluated. Results Early peripheral enhancement with progressive and concentric filling by contrast medium was the most frequent enhancement pattern (9 patients). A wedge-like enhancement area was observed in 10 patients. Ductal dilatation was found in 11 patients. Vascular involvement and extrahepatic invasion were seen in 8 and 2 patients, respectively. Conclusion Enhancement pattern is relative to the character of pathology (quantity and distribution of cell and fibrosis). Early peripheral enhancement with progressive and concentric filling by contrast medium may be specific for PCC.

Objective To compare the therapeutic efficacy of two different administration routes of insulin administra?tion on juvenile type 1 diabetes mellitus (T1DM) complicated with diabetic ketoacidosis(DKA). Methods A total of 223 cases of juvenile T1DM was included in this study, among which 98 were complicated with DKA. Insulin was delivered through either continuous subcutaneous insulin infusion(CSII) by insulin pump or via multiple subcutaneous insulin injec?tion (MSII). Recovery period of blood glucose, insulin doses that were adminstrated, the urinary ketone bodies clearance time, the recovering time from DKA and the frequency of hypoglycemia incidence were all compared between these two routes. Results Both CSII and MSII routes reversed blood glucose and DKA effectively. However the recovering time of blood glucose and DKA, insulin dosage,the urinary ketone bodies clearance time and the frequency of hypoglycemia inci?dence all improved better or quicker in CSII than in MSII. Conclusion CSII by insulin pump is safer and more effective than MSII in the treatment of junvenile T1DM with metabolic disturbance and diabetic ketoacidosis.

Objective To evaluate the efficacy of ultrasound?guided transversus abdominis plane ( TAP) block with different concentrations of ropivacaine for analgesia after cesarean section. Methods A total of 120 parturients, aged 24-31 yr, of American Society of Anesthesiologists physical statusⅠ or Ⅱ, weighing 64-73 kg, at 35 to 41 week gestation, scheduled for elective cesarean section, were randomly di?vided into 3 groups ( n= 40 each) using a random number table: 0?25% ropivacaine group ( group Ⅰ) , 0?20% ropivacaine group ( groupⅡ) , and 0?15% ropivacaine group ( groupⅢ) . A patient?controlled an?algesia pump was connected at the end of surgery, and the corresponding concentration of ropivacaine 1?5 mg∕kg was injected into the bilateral TAP under the guidance of ultrasound in each group. Visual analogue scale score was maintained ≤3. The number of attempt and the number of patients requiring rescue analge?sic were recorded at 48 h after surgery. The occurrence of TAP block?related complications was observed and recorded. Results Compared with groupⅢ, the number of attempt and the number of patients requi?ring rescue analgesic were significantly decreased in Ⅰ and Ⅱ groups ( P<0?05 ) . Compared with groupⅡ, the number of attempt and the number of patients requiring rescue analgesic were significantly de?creased in group Ⅰ (P<0?05). No TAP block?related complications were detected in the three groups. Conclusion Ultrasound?guided TAP block with 0?25% ropivacaine is helpful in improving the analgesic efficacy after cesarean section without serious complications.

Objective To investigate metformin combined with insulin aspart 30 injection (NovoMix 30) in the treatment of type 1 diabetes mellitus (T1DM) in children and adolescents. Methods A total of 126 T1DM children over 10 years of age were randomly divided into insulin group (A) and insulin + metformin group (B). A group (n=60) was given insulin aspart 30 injection (insulin aspart 30), and B group (n=66) was given the metformin and insulin aspart 30 injection (NovoMix 30). Results The two groups can effectively control blood glucose, but the B group in the blood glucose control time, insulin dosage, the incidence of hypoglycemia, fasting blood glucose and hospitalization time were better than those of A group. There was no significant difference in liver and kidney function before and after oral administration of metformin in B group (P>0.05). Conclusion Metformin combined with insulin is effective and safe in the treatment of children with T1DM.

AIM: To study the clinical characteristics of corneal perforation ( CP) .
METHODS:A retrospective analysis in July 1995 to July 2010 the First Affiliated Hospital of Fujian Medical University diagnosed CP 72 patients ( 72 eyes ) , clinical characteristics of all the patients were analyzed.
RESULTS: The incidence of corneal ulcer perforation rised year by year, the morbidity of male and female was 17:7, the onset age focused on 48 years old. Of 23 industrial workers ( 32%) with clear history of trauma, pathogeny identification results:top two:fungal infection and Acanthamoeba keratitis. A using history of glucocorticoid was found in 10 cases.
CONCLUSION:There are plenty of primary causes of CP such as traumas, fungal infection, Acanthamoeba keratitis, eroded keratitis, etc. CP happens in middle-aged males in Fujian province, most traumas are the causes, the main pathogenic bacteria is fungal infection.

Objective To investigate the value of the imaging division and features of CT and MRI in the differential diagnosis of benign and malignant space-occupying lesions.Methods A retrospective analysis of the clinical and imaging data of 201 patients with orbital space-occupying lesions confirmed by pathology was conducted.Four sector method was used to analyze the distribution of the lesions.The shape,border and relationship with surrounding tissues,MRI signal,CT density,and calcification of the orbital wall were also analyzed.Results There was statistical difference in the distribution of lesions in each of the 4-sector between orbital benign lesions and malignant tumors(χ2总=48.93,P=0.000).Lesions located in separate orbital zone including extra-periosteum compartment (18 cases),optic nerve compartment (4 cases),intraconal compartment(39 cases) were benign.Benign lesions (64%, 66/103) were more than malignant lesions (36%,37/103) in 103 lesions located in extraconal compartment.Additionally,there was significance in the distribution in separate and mixed zones between benign and malignant lesions(χ2=25.559,P=0.000).Benign lesions (77%,127/164) were more than malicious lesions(23%,37/164) in 164 cases in separate zone.Malignant lesions (65%,24/37) were more than benignant lesions (35%,13/37) in the 37 lesions located in mixed zone.Signs of CT and MRI:the benign and malignant lesions were 140 and 61,respectively.The features of those lesions are as follows(ratio=benign lesions/ malignant lesions):regular morphology(ratio=93/10),clear boundary(ratio=108/24),eyeball-surrounded (ratio=24/39),bone destruction (ratio=4/11).Features of lesions including shape,border,eyeball-surrounded, bone destruction had significant difference between benign and malignant lesions,whereas no differences was observed in calcification,signal on T1WI or T2WI,displacement of the eyeball and the occurrence of single or bilateral lesions.Conclusion The characteristic distribution of orbital space-occupying lesions based on the 4-sector and the features of CT and MRI has a great value in the diagnosis.

Objective To investigate the effect of exogenous hydrogen sulfide (H 2 S) on H2 S concentration and cystathionine β-synthase (CBS) expression in hippocampus in a rat model of vascular dementia (VaD). Methods A rat model of VaD was induced by using the modified four -vessel occlusion. The rats were divided into sham operation, model, low -dose and high-dose NaHS groups using the random number table method. They were further redivided into one day, seven -day, and 30-day subgroups according to the time after modeling. After modeling respectively, NaHS 30 μmol/kg and 100 μmol/kg were injected intraperitoneally every day in the low -dose and high-dose NaHS groups. The normal saline was injected intraperitoneally every day in the sham operation group and the VaD model group. Morris water maze test was used to evaluate the learning and memory ability of the rats. The expression of CBS in hippocampus was detected by real-time fluorescent polymerase chain reaction. Western Blotting was used to detect expression of CBS protein in hippocampus. Results Morris water maze test showed that the escape latencies of the model group, low -dose and high-dose NaHS groups were prolonged significantly compared with the sham operation group (P <0.05); the times of crossing the platform were decreased significantly compared with the model group (P <0.05); and the escape latencies were shortened significantly in the low -dose and high-dose NaHS groups compared with the model group ( P <0.05). The H2 S content in hippocampus was decreased significantly in the model group, low -dose and high-dose NaHS groups compared with the sham operation group, but the low -dose and high-dose NaHS group was significantly higher than that in the model group (all P <0.05). The expression of CBS mRNA and protein in the model, low -dose and high-dose NaHS groups was significantly lower than that of the sham operation group (all P < 0.05), and there was no significant difference between the low -dose and high-dose NaHS groups and the model group. Conclusions Exogenous H2 S may improve the learning and memory ability of the VaD rats. It may be associated with the increased H2 S content in hippocampus. However, it has no effect on CBS expression.
