Objective To explore the influence of intestinal trefoil factor (ITF) on interleukin-6(IL-6) in neonatal rat with necrotizing enterocolitis(NEC) ,and to discuss the protective machanism of ITF on NEC.Methods Thirty-two neonatal rats were divided randomly into four groups,group A as control group,group B as NEC group,group C as NEC+NS 0.2 mL group,group D as NEC+ITF 0.2 mg group.NEC model of neonatal rats were established.On the 4th day,all the subjects were put to death.Intestinal tissue within the boundary of ileum and cecum was obtained to observe histological changes.Other intestinal tissue was treated into homogenate.After the homogenate was centrifuged,supernates were used to test the density of IL-6.Results The density of IL-6 significantly decreased in group A,D than those in group B and C (Pa0.05).The pathological lesions indicated that intestinal tissue necrosis was severe in group B and C,which was graded as 3 points,but obviously lessen in group D,which was graded as 1 point,with ITF interfering.Conclusions Intestinal inflammation is ameliorated after ITF are injected hypodermically or intraperitoneally.ITF may provide a brand-new way for the therapy of NEC in neonatal rats.

Objective To investigate the clinical efficacy of radiofrequency ablation for the treatment of metastatic hepatic carcinoma.Methods The clinical data of 87 patients with metastasis hepatic carcinoma who received radiofrequency ablation (RFA) at the Southwest Hospital from January 2004 to December 2008 were retrospectively analyzed.Of the 87 patients,34 were with liver metastasis from colonic cancer,33 with liver metastasis from rectal cancer,12 with liver metastasis from pancreatic cancer,and 8 with liver metastasis from gastric cancer.The survival of the patients was analyzed by life score and kamofsky performance status (KPS)scale.Patients were followed up via phone call and out-patient examination.Ultrasonography,computed tomography,liver function and tumor markers test were done every month within postoperative 6 months,and every 2 months at 6 months later.The follow-up was ended in Novermber 2013.All data were analyzed using chi-square test or rank sum test.The survival curve was drawn by Kaplan-Meier method,and the survival rate was compared using the Log-rank test.Results Of the 87 patients,84 were successfully treated by RFA,and 3 patients gave up RFA because of unbearable pain (2 patients with colonic cancer and 1 with gastric cancer).A total of 129 metastatic lesions were detected in the 84 patients,and 107 metastatic lesions were ablated after single RFA,with the success rate of 82.95％ (107/129).The other 22 lesions were ablated after a second RFA.The mean duration of hospital stay was (10.7 ± 2.3) days (range,4-29 days).Before operation,the life quality was excellent in 60.7％ (51/84) of patients,good in 22.6％ (19/84) of patients,fair in 10.7％ (9/84) of patients,and poor in 6.0％ (5/84) of patients.The candition of 63.1％ (53/84) of patients was improved,29.8％ (25/84) of patients was stable,and 7.1％ (6/84) of patients was deteriorated.At postoperative month 6,the life quality was excellent in 78.2％ (54/69) of patients,good in 11.6％ (8/69) of patients,fair in 5.8％ (4/69) of patients,and poor in 4.4％ (3/69) of patients.The condition of 73.9％ (51/69) of patients was improved,21.7％ (15/69) of patients was stable,and 4.4％ (3/69) of patients was deteriorated.There were significant differences in the life score and KPS scale between patients before and after operation (x2 =29.760,17.140,P ＜ 0.05).All patients were followed up for 6-60 months.The 1-,3-,5-year survival rates of patients with liver metastasis from colonic cancer after RFA treatment were 68.8％,21.9％ and 6.3％,and the median survival time was 21.5 months.The 1,3,5-year survival rates of patients with liver metastasis from rectal cancer after RFA were 66.7％,27.3％,12.1％,and the median survival time was 19.5 months.The 1-,3-,5-year survival rates of patients with liver metastasis from pancreatic cancer after RFA treatment were 41.7％,0 and 0,and the median survival time was 8.5 months.The 1-,3-,5-year survival rates of patients with liver metastasis from gastric cancer after RFA treatment were 71.4％,14.3％ and 0,and the median survival time was 16.5 months.The survival rates of patients with liver metastasis from pancreatic cancer and gastric cancer were significantly lower than those with liver metastasis from colorectal cancer after RFA (x2 =9.169,P ＜ 0.05).Conclusion The efficacy of RFA for selected patients with liver metastasis from digestive tract tumors is satisfactory.

Objective To evaluate the efficacy of minimally invasive percutaneous intervertebral disc approach for treatment of sympathetic cervical spondylosis. Methods Fifty?six patients diagnosed as having sympathetic cervical spondylosis from January 2009 to August 2014, aged 22-64 yr, with the dis?ease course ranged from 6 months to 15 yr and a follow?up period of 6 months, were enrolled in the study. The related minimally invasive approach was selected according to the height of the diseased intervertebral space. When the ratio of the height of diseased intervertebral space∕normal intervertebral space≤1∕3, per?cutaneous radiofrequency ablation was used ( groupⅠ, n=19); when the ratio within the range of 1∕3-2∕3, percutaneous laser disk decompression was used ( groupⅡ, n=12); when the ratio≥2∕3, low?tem?perature plasma radiofrequency ablation was used ( group Ⅲ, n=25) . Before operation, at 2 weeks after operation, and at 1, 3 and 6 months after operation, the sympathetic symptoms were evaluated using the 20?point score. At 2 weeks and 6 months after operation, the patients′ subjective satisfaction was assessed and graded ( excellent, good, medium and poor ) . Results All the patients were followed up for 6 months. The sympathetic symptom scores were significantly lower at each time point after operation in Ⅰand Ⅲ groups and at 2 weeks and 3 and 6 months after operation in group Ⅱ than those before operation
( P<0.05) . The excellent and good rate of patients′subjective satisfaction was 67.9% at 2 weeks after op?eration, and 76.8% in the last follow?up period at 6 months after operation. Conclusion The minimally invasive percutaneous intervertebral disc approach has a marked short?term effect on sympathetic cervical spondylosis.

Objective To explore the pulmonary function,DVH and radiation pneumonitis after three-dimensional conformal radiation treatment ofⅢphase non-small-cell lung cancer.Methods 71 pa- tients (male 52,female 19,median age 63,KPS≥80) were evaluated by pulmonary function tests before radiotherapy and in M1 and M3 after radiotherapy respectively.After 3 months of follow-up time,it reviewed the appearance and grade of radiation pneumonitis.Then V_(20),V_(30) and MLD were worked out from dose vol- ume histogram.Results All patients completed radiotherapy,and total dose was 66-70 Gy.FVC (L), FEV1 (L) and CLCO were (2.58?0.65) L,(1.85?0.58) L and (15.15?4.65)ml/(min)before radio- therapy,with (2.96?0.76) L,(2.13?0.65) L and (14.71?3.92) ml/(min) in Ml after radiotherapy, with (2.65?0.61) L,(1.92?0.52) L and (13.15?3.71)ml/(min)in M3 after radiotherapy.The ac- cidence of radiation pneumonitis was 30%,moderate and severe radiation pneumonitis was 7%.With V_(20), V_(30) and MLD increasing,the grade of radiation pneumonitis was increasing.V_(20),V_(30) and MLD were related to the change in CLCO value among before,M1 and M3 after radiotherapy,and the correlation coefficient was more than 0.2.Conclusions There is a relationship in the pulmonary function,DVH and radiation pneu- monitis surely.The change in C_LCO value between before radiotherapy and M1 after radiotherapy could pre- dict the radiation pneumonitis.V_(20),V_(30) and MLD are not only correlated to radiation pneumonitis evidently but the change in FEV_1 and C_LCO after radiotherapy.

Objective: To investigate the neural connections between Shenmen (HT7)-heart and the brain by observing the tracing viruses co-labeled brain nuclear groups after injection of the pseudorabies viruses (PRV), the reverse transsynaptic virus tracer carrying different fluorescent protein genes, into the myocardium and Shenmen (HT7) point, respectively.Methods: Pseudorabies virus 531 (PRV531) carrying the green fluorescent protein gene and pseudorabies virus 724 (PRV724) carrying the red fluorescent protein gene were injected into the left ventricular wall and Shenmen (HT7) point area of the left forelimb of six C57BL/6 mice, respectively. After 120 h, whole brain tissue was extracted under 4％ paraformaldehyde perfusion to prepare brain sections. Neuronal co-labeling with the tracing viruses was observed under fluorescence microscopy. Results: Co-labeled signals from the mouse ventricular wall and Shenmen (HT7) point region were found at all levels of the mouse central nervous areas, such as the cerebral cortex, hypothalamus, midbrain, pons, and medulla oblongata. The number of co-labeled neurons was higher in the primary motor area, the hypothalamic paraventricular nucleus, the subceruleus nucleus, and the paramedian reticular nucleus. Conclusion: There is a neural connection between Shenmen (HT7), the heart, and the brain, which may be most closely related to the autonomic nervous system.

Objective To discuss the occurrence of anxiety in subarachnoid hemorrhage (SAH) patients and the analysis of correlation factors. Methods The occurrences of anxiety in 73 SAH patients were studied with a questionnaire. The correlations between the anxiety occurrence and the gender, age, education state, mode of medicine fee payment, SAH times, clinical symptoms, knowledge of the disease and complications were analyzed. Results The occurrence rate of anxiety in SAH patients was 53.4%. The female patients had a higher occurrence rate of anxiety than that of the males. Severe headache patients had a higher rate of anxiety than the slight ones. Hemorrhages times and complications had Obvious correlations with anxiety. Conclusions Correct understanding of anxiety is the precondition of expanding the intervention of positive emotion. Analyzing the anxiety-related factors and then actively giving the physiological therapy are the keys to the successful operation in SAH patients.
