This study is to establish the gastric hot model of rats. After gastric feeding with ethanol solution for 3 weeks and feeding with extra capsaicin and ethanol solution for another 2 weeks, model group show distinct physical sign of gastric hot syndrome. The pathology of gastrics reveals gastricism of model group, while treatment group (treat with Zuojin Wan) shows mild lesion. Elisa detection of model group show that the solution of interleukin-2 (IL-2) is higher than the blank group. The obvious difference among model group, treatment group and blank group reveals the success of the establishment of gastric hot model.

Objective To investigate the clinic value of enhanced CT-guided percutaneously transthoracic lung biopsy. Methods A total of 423 patients who underwent CT-guided percutaneously transthoracic lung biopsy were retrospectively analyzed. The percentage of specimen are satisfactory,the rate of sample with pathological findings,the number of cases with complications,the average goes of unsuccessful biopsy and the times of changing puncture point were compared between the enhanced CT group and the plain CT group. Results Compare parameters in patients whose procedure were guided with the enhanced CT group and with plain CT group, the average goes of unsuccessful biopsy, the times of changing puncture point in patients, the percentage of specimen that were satisfactory, the rate of sample with positive pathological findings and the rate that complicated with pneumothorax or hemorrhage show statistical significance.(3.08±1.05 vs 3.75±1.34, 8.52%vs 18.54%,90.13%vs 73.60%, 76.62%vs 63.36%, 15.51%vs 27.53%, 7.76%vs 14.04%, P<0.05). Conclusion In patient whose biopsys were guided by enhanced CT, the percentage of samples that are satisfactory is higher, the incidence of complication is fewer and the sample with pathological finding is higher compared to those in patients whose biopsys were guided by plain CT. Therefore, enhanced CT-guided percutaneous transthoracic biopsy is more valuable than plane CT.

Objective To evaluate the surgical effects of laparoscopic pancreaticojejunostomy in pigs and investigate the learning curve. Methods A total of 40 porcine cases of laparoscopic pancreaticojejunostomy were performed by a single surgical team from September 2012 to February 2013.According to the operation sequence, pigs were divided into 4 groups with 10 in each group.For analyzing the efficacy of surgery in different stages, the operation time and efficacy of anastomoses were compared between these groups. Results The operation was finished successfully in all the 40 cases.There were statistical significances in operation time among the four groups.The group Ⅳ had significant shorter time (112.7 ±8.3) min than those in the group Ⅰ [(145.1 ± 16.6) min, q=9.154, P<0.05], the groupⅡ[(133.0 ±8.7) min, q=5.735, P<0.05], and the group Ⅲ[(137.2 ±9.0) min, q=6.922, P<0.05], respectively.There was no difference between the group Ⅱ and the group Ⅰ in operation time (q=3.419, P>0.05), so as to other groups.The results of anastomoses among the four groups were not significantly different (χ2 =0.586,P=0.900). Conclusions Laparoscopic pancreaticojejunostomy in pigs is feasible.The learning curve of the operation is about 30 cases.

Objective To explore the clinical prognostic value of rapid detection for plasma NT-proBNP levels on admission in patients with acute myocardial infarction.Methods 56 patients with AMI were measured plasma NT-proBNP imediately in hospital,and then they were divided into A,B and C group according to NT-proBNP levels (A group:< 500ng/L,B group:500-2 000ng/L,C group:> 2 000ng/L).The incidence of major adverse cardiac events (MACE including congestive heart failure,malignant arrhythmia,cardiogenic shock and sudden cardiac death) in subjects were observed respectively during hospitalisation and 30 days.Results The three group subjects with different NT-proBNP levels presented different incidence of MACE(A group:1,0;B group:3,1;C group:8,6) at duration of hospital stay,30days (x2 =6.705,P =0.035 ; x2 =7.957,P =0.008).With the NT-proBNP levels rising in AMI paitents,the inciedence of MACE increased.The incidence of MACE in A,B and C group were 6.6%,18.18% and 73.69% respectively.Conclusion In AMI patients,plasma NT-proBNP levels could predict early MACE incidence,which has an important value to evaluate the early clinical prognosis.

Objective To determinate whether the first post-operative day serum parathyroid hormone (PTH) is more effective than serum calcium in predicting hypocalcemia after total thyroidectomy.Methods According to PTH level on the first post-operative day,104 patients after total thyroidectomy were divided into different groups.Patient's serum calcium was measured,the number of patients who developed hypocalcemia and the time for calcium supplement were recored.Results Serum PTH was more accurate in predicting hypocalcemia than serum calcium.There were 26 patients whose PTH value was < 5 pg/ml,among whom 7 patients had transient hypocalcemia and symptoms,while 5 of them developed hypocalcemia for long time and needed long-term calcium supplement.The positive predictive value of group PTH value < 5 pg/ml was 28%,and the accurate rate was 46%,higher than other groups.Besides,the positive predictive value and the accurate rate of PTH value < 5 pg/ml was higher than serum calcium.Conclusion Serum PTH is more effective in determining hypocalcemia after total thyroidectomy than serum calcium,and PTH value < 5 pg/ml on the first post-operative day is a reliable marker in predicting hypocalcemia after total thyroidectomy.

Sonic hedgehog (Shh) signaling has recently been shown to be involved in the pathological angiogenesis in response to tissue hypoxia and ischemic injury. Hypoxia/ischemia is considered to play an important role in the development of choroidal neovascularization (CNV). This study was aimed to examine the effect of blockade of the Shh signaling pathway on CNV and the underlying mechanism. A total of 64 male Brown-Norway (BN) rats were used in this study. One eye of each rat underwent laser photocoagulation. The other eye served as normal control. After the laser treatment, the 64 rats were divided into four groups (n=16 in each group): Blank control group, in which no intravitreal administration was given; cyclopamine group, recombinant Shh N-terminals protein (rShh) group and phosphate-buffered saline (PBS) group, in which cyclopamine (a Shh inhibitor), rShh (a Shh activator) and PBS were intravitreally injected into the laser-treated eyes respectively every other day for a total of four intravitreal injections immediately after the laser treatment. Fourteen days after the intravitreal administration, the changes of CNV-related variables, including positive CNV lesion percentage, CNV membrane area and CNV membrane thickness, were evaluated by fluorescein angiography, indocyanine green angiography and pathological examinations. The mRNA and protein expression of PTCH1, Gli1, HIF-1(α), VEGF and DLL4 in each group on 14 days of CNV model was detected by real-time quantitative PCR and western blot analysis, and the relationship between the Shh cascade and the HIF-1(α)-VEGF-DLL4 cascade in CNV was analyzed. The results showed that the CNV membrane area and the CNV membrane thickness were decreased by 62.5% and 41.9% in the cyclopamine group and increased by 85.7% and 64.3% in the rShh group in comparison to those in the blank control group (P<0.01 for each). There was no significant difference in the CNV membrane area and thickness between the blank control group and PBS group (P=0.102 and P=0.063, respectively). Real-time quantitative PCR revealed a 5.23-, 4.14-, 2.97-, 2.78- and 2.39-fold up-regulation of the mRNA expression of PTCH1, Gli1, HIF-1(α), VEGF and DLL4 genes in the laser-treated eyes compared with the normal control eyes in the control group. In the cyclopamine group, the mRNA and protein expression of Gli1, HIF-1(α), VEGF and DLL4 was significantly down-regulated (P<0.05 for each) while the expression of PTCH1 showed no significant changes at the mRNA (P=0.293) and protein level (P=0.304). The mRNA expression and protein expression (P=0.001 and P=0.021, respectively) of PTCH1, Gli1, HIF-1(α), VEGF and DLL4 was significantly increased in the rShh group when compared with the control group. The expression level of these genes was related to the severity of the CNV. It was concluded that intravitreal administration of cyclopamine can effectively inhibit the formation of laser-induced experimental CNV by down-regulating the expression of the HIF-1(α)-VEGF-DLL4 cascade in CNV. The Shh signaling pathway as an upstream signaling pathway of HIF-1(α)-VEGF-DLL4 cascade is implicated in the development of experimental CNV.
