Objective To investigate whether enteric nervous system(ENS)involve in mediating the effect of short pulse gastric electrical stimulation on c-fos expression in nucleus tractus solitarius (NTS)and hypothalamus.Methods Fifteen Wistar rats were divided into control group,gastric electrical stimulation(GES)group and ENS free group with 5 rats each.A pair of electrodes was implanted on the gastric serosa.In ENS free group,0.5%benzalkonii chloridum was applied on the serosa during the surgery.A set of short pulse GES with frequency of 20 cpm,pulse width of 300 μs and amplitude of 2 mA was applied via the electrodes for 30 rain in the stimulation group and ENS free group.The c-fos expression in NTS/hypothalamus was detected 1 h after the stimulation.Results The number of neuron with c-fos expression was(71.6±7.4)/HP in NTS group and(63.4±10.8)/HP in ENS free group,both were significantly higher than those in control group(36.4±8.6/HP,P＜0.05).The number of neuron with c-fos expression in hypothalamus was higher in GES[(224.2±47.3)/HP]and ENS free groups[(249.1±44.0)/HP]compared with control group[(90.2±47.3)/HP,P＜0.05].There was no significant difference in c-fos expression in NTS/hypothalamus between GES group and ENS free group(P＞0.05).Conclusions Short pulse gastric electrical stimulation significantly increases c-fos expression in NTS/hypothalamus,which suggests that NTS/hypothalamus may participate in mediating the effect of GES on gastric function.This effect may be not mediated by ENS.

0.05 ),respectively. Conclusions:Modified radical neck dissection with internal jugular vein preservation may have similar therapeutic effect to radical neck dissection.

Purpose To study the correlation between the expression of podoplanin-positive stromal cells and clinicopathologic features in squamous cell carcinoma ( SCC) of esophagus, and to explore the role of podoplanin-stromal cells in the progression of SCC of e-sophagus. Methods Immunohistochemical EnVision method was used to detect the expression of podoplanin in the stromal cells of e-sophageal SCC. The correlation between the expression of podoplanin-positive stromal cells and clinicopathologic features in SCC of e-sophagus was analyzed. Results Of 69 cases of SCC, podoplanin-positive stromal cells were seen in 43 and the positive rate was 62. 3%. Lymphatic vessel density in SCCs with podoplanin-positive stromal cell was 45. 72 ± 14. 36, which was higher than that with-out podoplanin-positive stromal cell (21. 23 ± 10. 49) (P<0. 01). Expression of podoplanin in stromal cells in SCCs with lymphatic vessel invasion was higher than those without lymphatic vessel invasion (P<0. 05). There was no correlation between podoplanin-posi-tive stromal cells and age, sex, tumor size, the depth of invasion, differentiation, lymph node metastasis, and clinical stage ( P>0. 05). Conclusion Podoplanin-positive stromal cells may promote the lymphangiogenesis and lymph vessel invasion of esophageal SCC.

Objective: To investigate the quality of life of patients with chronic prostatitis. Methods: Two hundred patients were included and tested with WHOQOL-100 . Results: Compared with normal controls, the following aspects had no significant difference, including energy and fatigue, appearance and status, working activity, daily life and environment. There were significant difference to controls in other 6 fields and 20 aspects. The major factors that do harm to QOL include satisfaction on life, income and depression. Conclusion: It should deserve the clinician's attention that the QOL of patients with chronic prostatitis is greatly lower than that of the normal controls.

Objective To investigate the distribution and expression of Oceludin in esophageal epithelium in gastroesophageal reflux disease (GERD).Method Immunohistochemistry was used to examine the distribution and expression of Occludin in esophageal epithelium from 62 cases with GERD and 10 Case with other diseases ag control.Results The Occludin was normal continuous membrane expressed in 10 contrast esophageal epithelium,while in 32 nonerosive reflux disease patients,normal expression Was seen in 4 cases,different degree of abnormal expression was seen in 28 cases,including incomplete membrane expression,cytoplasmic expression and expression depletion respectively,and in 30 reflux esophagitis patients were seen all abnormal expression including incomplete membrane expression,cytoplasmic expression and expression depletion respectively.There was significant difference between nonerosive reflux disease and normal contrast,reflux esophagitis and normal contrast(P＜0.01),no difference was seen between reflux esophagitis and nonerosive reflux disease(P＞0.05).Concision The number of esophageal epithelial Occludin in GERD patients diminished and abnormally distributed,interfered the integrity of epithelium mucosal barrier,which might be one ofthe pathogenesis of GERD,there is no difference of Occludin expression between reflux esophagitis and nonerosive reflux disease esophageal epithelium.

Objective To evaluate clinical features, therapeutic regimen and prognosis of unexplained rhabdomyolysis. Method Clinical manifestations, therapeutic regimen and prognosis were recorded in 23 patients,who were admitted to The First Affiliated Hospital of Nanjing Medical University 13 to 27 August,2010.The 23 patients were diagnozed as unexplained rhabdomyolysis. Results The patients all presented myalgia of upper body,like neck,waist and back,maybe with asthenia, nausea,dyspnea,abdominal pain, red urine or changed color of urine. Laboratory examination: obviously step-up of creatine kinase [CK: (4655 ± 2556) U/L( normal: 25 ～ 190U/L) AST:(141 ±78) U/L(normal:10～45 U/L),LDH:(348± 127) U/L(normal: 110～ 250 U/L)]and myoglobin[( Mb ＞ 1000 μg/L (normal: 0 ～ 50 μg/L)]. Therapeutic regimen included treatment of the underlying diseases, volume repletion, alkalization and dealing with the complications. No patients developed acute renal failure.All the patients recovered. Conclusions Rhabdomyolysis is a syndrome with different clinical manifestations.However, early diagnosis, proper treatment could prevent serious complications,and prognosis is good.

AIM: Utilizing mRNA fluorescent differential display RT-PCR in our previous study,we found that the mRNA expression level of an intermediate protein(IF)-desmuslin was dramatically down-regulated in the abnormal veins of patients with primary vein incompetence.In this study,we testified the alteration of desmuslin expressing style at gene transcription and translation levels.METHODS: Specific PCR primers were designed according to the sequence of desmuslin mRNA.The cDNA fragments of desmuslin obtained from differential display were labeled by DIG as specific probes.Then semi-quantitative RT-PCR and Northern blotting techniques were applied to investigate the expression level of desmuslin mRNA in normal and abnormal veins.Simultaneously,the specific single-cloned antibody bestowed by Yuji Mizuno was used to evaluate the amount of DMN protein in the two groups by Western blotting and immunohistochemical techniques.RESULTS: In the abnormal veins isolated from the patients with primary vein incompetence,the expression of desmuslin mRNA was significantly down-regulated,compared with that in control group(semi-quantitative RT-PCR: 0.19?0.05 vs 0.83?0.08,P

Objective To investigate the surgical treatment of infected femoral pseudoaneurysm caused by injection of heroin. Method Retrospective analysis was made on the clinical data of 14 cases of infected ruptured femoral pseudoaneurysm caused by injection of heroin. Results All 14 cases underwent operation. The ruptured sizes of arteries were 0.5 cm-2.0 cm . All cases were treated by resection of the aneurysm and replacement of iliac-femoral artery with artificial graft. Blood supply and function were good in all limbs after operations. Aneurysm cavities and incision wounds were treated with debridement, drainage and anti-infective treatment. All wounds were healed. 2 weeks and 3 months after operation, the grafts were patency demonstrated by Color Doppler examination. None of them was complicated with anastomosis leakage or thrombosis. Conclusion Thorough debridement of aneurysms and reconstruction of the artery are the effective approach in treating the infected ruptured femoral pseudoaneurysm caused by injecting heroin. Sufficient drainage, anti-infective and anti-coagulation therapy should be considered after the operation.
