ABSTRACT

@#We reported a 32 years female patient in whom lung metastasis from breast cancer was presented as solitary pulmonary pure ground-glass opacity (GGO) lesion. The patient received rational preoperative examinations and surgery though the preoperative diagnosis was not accurate. Because of different therapy strategies and purposes, it is crucial to make distinction of atypical metastases from primary cancers. Thus, for patients with a history of malignancy, possible metastasis should be taken into consideration if new GGO was found on the CT. Besides this, the follow-up interval of CT should be shortened appropriately, preoperative examinations and surgical procedures should be made according to the suggestions of multidisciplinary team.

ABSTRACT

@#The sternum is the pivotal component of the thoracic cavity. It is connected with the clavicle and ribs on the upper part and both sides respectively, and plays an important role in protecting the stability of the chest wall. Sternal resection usually results in a large segmental chest wall defect that causes the chest wall to float and requires sternal reconstruction. This paper reports a 62 years male patient with thymic squamous cell carcinoma with sternal metastasis, who underwent thymotomy, sternal tumor resection and autologous lilum graft combined with sternal reconstruction by titanium plate after relevant examination was completed and surgical contraindications were eliminated. The patient was followed up for 6 months, the respiratory and motor functions were normal and the thoracic appearance was good.

ABSTRACT

@#Objective    To investigate the prognostic survival status and influence factors for surgical treatment of esophageal squamous cell carcinoma (ESCC) in pathological stage T1b (pT1b). Methods    The patients with ESCC in pT1b undergoing Ivor-Lewis or McKeown esophagectomy in Lanzhou University Second Hospital from 2012 to 2015 were collected, including 78 males (78.3%) and 17 females (21.7%) with an average age of 61.4±7.4 years. Results    The most common postoperative complications were pneumonia (15.8%), anastomotic leakage (12.6%) and arrhythmia (8.4%). Ninety-three (97.9%) patients underwent R0 resection, with an average number of lymph node dissections of 14.4±5.6. The rate of lymph node metastasis was 22.1%, and the incidence of lymph vessel invasion was 13.7%. The median follow-up time was 60.4 months, during which 25 patients died and 27 patients relapsed. The overall survival rate at 3 years was 86.3%, and at 5 years was 72.7%. Multivariate Cox regression analysis showed that lymph node metastasis (P=0.012, HR=2.60, 95%CI 1.23-5.50) and lympovascular invasion (P=0.014, HR=2.73, 95%CI 1.22-6.09) were independent risk factors for overall survival of pT1b ESCC. Conclusion    Esophagectomy via right chest approach combined with two-fields lymphadenectomy is safe and feasible for patients with pT1b ESCC. The progress of pT1b ESCC with lymph node metastasis or lymphovascular invasion is relatively poor.

ABSTRACT

Irritable bowel syndrome( IBS)is a commonly seen chronic functional bowel disease,the prevalence showed a rising trend in recent year in China. At present,the etiology and pathogenesis of IBS have not yet been fully elucidated,and may be related to intestinal gas. Intestinal gas is usually composed of 59% N2 ,21% H2 ,9% CO2 ,7%methane(CH4 )and 4% O2 ,in which H2 and CH4 are produced only by intestinal bacteria metabolism. IBS patients usually manifested as having abdominal distension and symptoms of flatulence,suggesting the occurrence of accumulation of intestinal gas. In recent years,the relationship between symptoms of IBS and intestinal gas has attracted much attention. This article reviewed the progress in study on symptoms of IBS and intestinal gas.

ABSTRACT

Endocannabinoids and cannabinoid receptors are expressed in various central pain modulation regions. They maintain in dynamic changes in the expression level and distribution under different pathological and physiological conditions. These changes possess advantage as well as disadvantage. Exogenous administration of endocannabinoids exerts analgesic effect in different pain models, which is mainly mediated by the cannabinoid CB1 and CB2 receptors. Inhibition of enzymes for degrading endocannabinoids in different pain models also shows analgesic effect due to the increased local levels of endocannabinoids.

ABSTRACT

ObjectiveTo observe the effect of donor liver pretreated by breviscapine on liver transplantation ischemia/reperfusion injury in rats. Methods SD rats served as liver donors and recipients (n =48 each).The recipients were divided into four groups by random number table.The donors in groups A and C were not pretreated with breviscapine,but those in groups B and D were pretreated with 20 mg/L Breviscapine.The cold ischemia time in donor livers of groups A and B was 30-40 min,and that in groups C and D was 12 h. Clotting function, liver function, serum thrombomodulin,caspase3,and relative activity of NF-kB after liver transplantation were assessed,and the pathological changes and TUNEL apoptosis staining were observed.ResultsThe mortality in groups C and D was 40.0% (8/20) and 29.4% (5/17),respectively (P>0.05).There were no significant changes in coagulation function in all groups after operation. The liver function was improved,pathological lesions were alleviated,and apoptosis rate,serum TM,caspase3 expression and activity of NF-kB in the liver tissues of group D were significantly decreased as compared with group C at 3rd day after operation (P<0.01),but all these parameters in group B had no significant change compared to group A.ConclusionPretreatment of donor livers with breviscapine can reduce the ischemia/reperfusion injury and apoptosis after liver transplantation in rats probably by inhibiting the apoptosis-related pathway and alleviating the damage to the endothelial cells of the liver microcirculation.
