Objective The study was performed to analyze the diagnosis and treatment of blue rubber bleb nevus syndrome of Chinese patients by evaluating the researches in China.Methods Chinese Journal Full-text Database,Wangfang Data and Weipu Chinese Medical Journal Database were searched for the clinical data of the patients with blue rubber bled nevus syndrome.Results Among the 50 patients,31 cases were male,and 19 cases were female.All patients (100％) had the venous malformations of the skin.Thirty-five (70％) cases had melena,13 (26％) cases had bloody stool,and 35(70％) had dizziness and palpitation.Blue rubber bled nevus syndrome were diagnosed with gastroscopy (40/48,83.33 ％),coloscopy (30/41,73.17％) and small intestinal examination (23/25,92％).Fourteen cases received symptomatic treatment.Twelve cases received therapeutic endoscopy,which lesions were located in stomach and colon.Sixteen cases received operation,and 2 cases were treated by laparoscopy and endoscopy.Conclusions Blue rubber bleb nevus syndrome is a rare disease.The skin and gastrointestinal system are involved in all patients with blue rubber bleb nevus syndrome in China.The routine examination for diagnosis of blue rubber bleb nevus syndrome should include examination of the small intestine.It still needs further research about effective treatment of blue rubber bleb nevus syndrome.

Objective To evaluate the efficacy and safety of endoscopic mucosal resection (EMR) for rectal carcinoid tumors. Methods From January 2006 to January 2009, EMR was performed in 28 patients with rectal carcinoids, who were followed up to evaluate the therapeutic effect and safety. Results Tumor diameters varied from 0.4 cm to 1. 2 cm (mean 0.7± 0. 2 cm). Negative resection margin was a-chieved in 26 cases (92. 9% ), tumor margin within 0. 1 cm of resection margin in 1 (7. 1% ) , and two margins coincided in 1 patient (7. 1% ). Hemostasis was performed with metal clips in 14 patients (50% ) and argon plasma coagulation (APC) in 9 (32. 1% ). Except for rectal bleeding in 1 patient (3. 6% ) , no other complications were observed. There was no recurrence in any patients during a follow-up of 6-36 months. Conclusion EMR is a useful and safe method for treatment of small rectal carcinoid tumor which does not cross submucosal layer.

ObjectiveTo determine the cerebral protection effect and mechanism of propofol on global cerebral ischemia and reperfusion damage in rats.Methods19 adult male Wistar rats were randomly divided into 3 groups, ischemia group (n=7), propofol group (n=7), and sham injury group (n=5). Global cerebral ischemia and reperfusion model were made by means of Pulsinelli's method. Rats in propofol group were anesthesia with propofol at the dosage of 1.5 ml/h for 30 min at the beginning of reperfusion. Apoptosis and necrosis rate were detected by cytometry. In the same time, bcl-2, Bax and p53 protein expression in hippocampus neurons were detected. ResultsThe apoptosis and necrosis rate in propofol group were significantly decreased as compared with ischemia group ( P<0.05). Bax and p53 protein expression in hippocampus neurons were also significantly decreased as compared with ischemia group (P<0.05), however, no significant findings in bcl-2 protein expression (P>0.05).ConclusionPropofol can decrease apoptosis and necrosis rate in cerebral ischemia reperfusion injured neuron, and the mechanism maybe related to decreasing the expression of Bax, p53 protein.

Objective To investigate the clinical effects of gastrointestinal decompression with enteral feeding tube in elderly patients with gastric cancer.Methods 78 cases of gastric cancer patients undergoing postoperative gastric decompression with enteral feeding tube were selected as the treatment group,and 66 patients with gastric cancer undergoing postoperative intravenous nutrition and gastric decompression with routine nasogastric tube as the control group in our hospital from January 2015 to December 2015.The incidence rate of gastric tube patency,faster postoperative recovery,nutritional immune improvement,adverse reaction and complication were compared between the two groups.Results The incidence rate of adverse reactions and complications in treatment group were significant lower than in control group (3.0 ％ vs.12.8 ％,x2 =4.4857,P =0.0342;1.5 ％ vs.10.2％,x2 =4.6620,P =0.0308,respectively).Following parameters were significant better in treatment group versus in control group:the time of evacuating [(3.1 ± 0.3) d vs.(4.0 ± 0.1) d,t =24.9227,P =0.0000],defecation[(4.3 ± 0.6) d vs.(5.5 ± 1.1) d,t =7.9189,P =0.0000],extubation [(5.3±1.3)d vs.(10.1±2.2)d,t=15.5690,P=0.0000],hospitalization[(12.3±2.5)d vs.(18.6± 3.2)d,t=12.9864,P=0.0000],postoperative body weight[(57.2±4.9)kg vs(49.0±7.2)kg,t=-7.8408,P=0.0000],plasma protein[(133.2± 11.2)g/L vs(104.5± 10.3)g/L,t=-16.0055,P=0.0000],hemoglobin[(4.7 ± 1.0) g/L vs (3.2 ± 0.6) g/L,t =-11.0991,P =0.0000] and peripheral blood lymphocyte count[(3.5 ± 0.7) × 109/L vs (2.1 ± 0.4) × 109/L,t =-15.0088,P =0.0000].Conclusions Effects of postoperative gastrointestinal decompression in elderly patients with gastric cancer are similar between with routine gastric tube and with enteral feeding tube.However,the enteral feeding tube-induced enteral nutrition shows fewer side effects and complications,better nutritional and immune effects,and faster postoperative recovery,which is worthy of a generalization and application.

Objective To investigate the incidence of and risk factors for benign prostatic hyperplasia (BPH) in transplant recipients.Methods 197 males aged 50 years and older who received kidney transplants were recruited if they were clinically stable.They were divided into three age groups:50 to 59 years (87 cases),60 to 69 years (64 cases) and ≥ 70 years (46 cases).Two hundred and forty people who had not undergone kidney transplant were randomly selected from the community as controls.A cross-sectional study was performed to study the BPH incidence in kidney transplant recipients according to standard diagnostic criteria.At the same time,the expression levels of keratinocyte growth factor,transforming growth factor-β and serum testosterone and the CD4/CD8 ratio in T lymphocytes were determined.Results There was no significant difference in age,PSA and the postmicturition residual volume between the study group and the control group.The total BPH incidence in kidney transplant recipients was 16.2％ (32/197).The symptomatic BPH incidence was 6.9％ (6/87) in the 50-to 59-year-old study group and 20.2％ (19/94) in the control group,representing a significant statistical difference in the symptomatic BPH incidence between the two groups (P =0.010).The symptomatic BPH incidence was 18.8％ (12/64) in the 60-to 69-year-old study group and 41.9％ (34/81) in the control group,indicating a significant statistical difference in the symptomatic BPH incidence between the two groups (P =0.004).The symptomatic BPH incidence was 30.4％ (14/46) in the ≥ 70-year-old study group and 52.3％ (34/65) in the control group,indicating a significant statistical difference in the symptomatic BPH incidence between the two groups (P =0.032).Compared to the control group,the peripheral blood serum testosterone level (9.4 ± 4.7,18.2 ± 5.6,P =0.040) and the CD4/CD8 ratio (1.1±0.3,1.8±0.3,P=0.014) of kidney transplant recipients was lower.The transforming growth factor-β expression level (5015± 1087,1829±963,P＜0.001) was higher in kidney transplant recipients than in the control group.The kasatinocyte growth factor expression levels (35.8±20.7,21.0± 18.3,P =0.064) was not statistically different than in the control group.Conclusions Kidney transplant recipients who had long-term administration of calcineurin inhibitor might have a low benign prostatic hyperplasia incidence,which might be related to transforming growth factor-β and keratinocyte growth factor expression,testosterone levels and the lymphocyte infiltration.Further high-quality prospective studies are still needed to confirm the conclusions.

Glioma is the most malignant tumor in the brain, the origin of glioma is still unknown. Recently some papers indicated that glioma may be developed from cerebral cavernous malformation (CCM). We describe a man with a right temporal lobe CCM, after gamma-knife radiotherapy, the patient developed a low-grade astrocytoma in the area of the preexistent CCM. This case, together with other reports, may indicated an oncogenetic properties of CCM, and we proposed that CCM may be a pre-glioma lesion.
