Objective To explore the diagnosis and management of functional pancreatic endocrine tumor.Methods Clinical data of 19 cases of functional pancreatic endocrine tumor were retrospectively analyzed.Results 15 cases of insulinoma,2 cases of gastrinoma and 2 cases of glucagonoma were qualitatively diagnosed.The positive rate of preoperative diagosis for type B ultrasonic inspection,CT,MRI,EUS,selective portovenous sampling and intraoperative type B ultrasonic inspection was 15.8％ (3/19),67.5％ (10/16),71.4％ (5/7),87.5％ (7/8),100％(2/2) and 85.7％(6/7) respectively.Of the total 19 cases,7 cases underwent open surgery,11 cases unde rwent laparoscopic surgery,and one case didn't undergo any surgery as liver metastasis had occurred when glucagonoma was diagnosed.The operation methods included tumor enucleation (n=13),distal pancreatic resection (n=3),distal pancreatic resection plus splenectomy (n=1),and pancreatic head resection with duodenum preserved (n=1).Conclusions The measurement of serum insulin,gastrin and glucagon is the main basis for qualitative diagonosis of pancreatic endocrine tumor.Two stage spinal CT thin scanning is the main method for tumor location.Intraoperative type B ultrasonic inspection is the supplement to preoperative location.Tumor enucleation is the main choice of treatment.

Objective To investigate the efficacy of postoperative concurrent chemoradiotherapy for early-stage cervical adenosquamous carcinoma and adenocarcinoma.Methods A total of 62 patients with cervical adenosquamous carcinoma,149 patients with cervical adenocarcinoma,and 2687 patients with cervical squamous cell carcinoma,all of whom were in stage Ⅰ B-Ⅱ A and were treated from 2006 to 2012,were enrolled,and some of them received postoperative pelvic radiotherapy ± para-aortic extended field radiation ±afterloading radiotherapy.The chemotherapy regimen consisting of DDP,TP,and FP was given to these patients.The chi-square test was used for comparison of general clinical data,the Kaplan-Meier method was used for calculating survival rates,and the log-rank test was used for survival difference analysis.Results Cervical adenosquamous carcinoma and adenocarcinoma had no significant differences in clinicopathological features (P=0.107-0.639).The high-risk patients with adenocarcinoma had a higher recurrence rate than their low-risk counterparts even after adjuvant radiotherapy or chemoradiotherapy (P=0.000).In the patients treated with surgery and radiotherapy,those with adenosquamous carcinoma had the shortest median survival time,followed by those with adenocarcinoma and squamous cell carcinoma (P =0.134,0.787);in the patients treated with surgery and concurrent chemoradiotherapy,those with adenocarcinoma had the shortest median survival time,followed by those with adenosquamous carcinoma and squamous cell carcinoma (P=0.131,0.643),and the median survival time showed a significant difference between the patients with adenocarcinoma and those with squamous cell carcinoma (P =0.000).In the patients with adenosquamous carcinoma and adenocarcinoma,the patients treated with postoperative concurrent chemoradiotherapy had higher incidence rates of short-term adverse reactions than those treated with postoperative radiotherapy (P=0.037,0.003),but the incidence rates of long-term adverse reactions showed no difference between the two groups of patients (P=0.861,0.655).In the patients with adenosquamous carcinoma,the patients treated with postoperative concurrent chemoradiotherapy had a lower rate of distant metastasis (P =0.003) and prolonged median overall survival and disease-free survival (both increased by 17 months) (P=0.811,0.799),as compared with those treated with postoperative radiotherapy,while in the patients with adenocarcinoma,the median overall survival and disease-free survival were reduced by 11 and 9 months,respectively (P=0.330,0.115).Conclusions Compared with postoperative radiotherapy,postoperative concurrent chemoradiotherapy for early-stage high-risk cervical adenosquamous carcinoma can reduce the rate of distance metastasis.Compared with radiotherapy,postoperative concurrent chemoradiotherapy for adenosquamous carcinoma and adenocarcinoma cannot improve survival time.

Objective To explore the safety and efficacy of hepatic resection with selective hepatic vascular exclusion(SHVE). Methods SHVE was used in 246 consecutive patients undergoing major or complex liver resection in our center. Preoperative demographic and clinical data,details of the surgical procedure, pathologic diagnosis, postoperative course and complications were collected and analy zed. Results From January 2000 to July 2007, liver resections were performed IJnder SHVE in 246 patients; total SHVE, right partial SHVE and left partial SHVE in 145, 54 and 47 patients, respectively. SHVE was converted to total hepatic vascular exclusion(THVE)in 3 patients to repair the wall of inferior vena cava(IVC). Hemodynamic tolerance to SHVE was excellent, only with a slight increase in systemic and pulmonary vascular resistance during clamping.There were no deaths. and the morbidity was 24.8%.The mean leyth of hospital stay was 9.6 days(range 8-18) .Conclusion Our study showed that SHVE is a safe and effective procedurei and it is applicable to liver tumors near but not invade the inferior vena cava.

OBJECTIVE To study the gene chip joint pyrosequencing technology in the newborn genetic deafness gene mutation screening, and provide a theoretical basis for the early diagnosis and prevention of genetic deafness. METHODS 2000 Neonatal EDTA umbilical cord blood was collected and genomic DNA (gDNA) was extracted. Microarray chip was used to detect four deafness gene at 9 mutation sites. And the positive result of gene chip detection was verified by pyrosequencing.RESULTS Among the GJB2 mutations, there were 1 case of 35delG mutation type, 3 cases of 176 del16 mutation type, 57 cases of 235del C mutation type, 9 cases of 299 del AT mutation type, 6 cases of GJB3 gene 538C>T mutation type. There were 5 cases of 1555A>G mutations and 1 case of 1494C>T mutations in mitochondrial 12S rRNA. There were 6 cases of 2168A>G mutation type and 23 cases of IVS7-2A>G mutations in SLC26A4. 103 cases of newborns carry the mutated gene in 2,000, the gene mutation rate is 5.15%. CONCLUSION All the four genes mutation at nine mutation sites are found in newborns with family history of non-hereditary deafness, and GJB2 gene mutation is common. The screening of genetic deafness in newborns is very important for early diagnosis and prevention of hereditary hearing loss. In particular, the diagnosis of mitochondrial 12S rRNA gene mutation can prevent the occurrence of deafness caused by drug use, for the genetic mutation of these carriers' health is of great significance.

Objective To compare the egicacy and security of intracoronary administration of tirofiban combined high-dose adenosine during percutaneous coronary intervention (PCI) in patients with acute myocardial infarction (STEMI).Methods Eighty-eight cases with STEMI were randomly divided into observation group(44 cases) who were accepted 2 times intracoronary adenosine(2 mg,10 ml 0.9％ NaCl),and control group(44 cases) who were afforded only 10 ml 0.9％ NaCl by prospective,double-blind,and random study.The two groups were received10 g/kg tirofiban after aspiration catheter in the culprit lesion distal bolus injection of 3 rain,at the same time,continuous infusion of 0.15 g/(kg · min) for 24 h.The postoperative coronary arteriography and electrocardiogram were evaluated.Meanwhile,the postoperative myocardial blush grade(MBG),thrombolysis in myocardial infarction (TIMI),corrected TIMI frame counts (CTFC),ST-segment elevation resolution (STR) major adverse cardiac events (MACE),and adverse reactions of adenosine were recorded.Results There was no significant difference in terms of postoperative TIMI and STR between two groups (P ＞ 0.05).The CTFC of observation group was (24.4 ± 4.9) frames,significant better than that of control group((21.9 ±3.7) frames;t =2.701,P ＜0.01).The ratio of MBG in observation group was 24/44,higher than that of control group(14/44 ; x2 =4.632,P ＜ 0.05).There were no significant difference regarding of the ratio of death,MACE,target vessel revascularization,grade of NYHA between observation and control group at followed up for 1 and 12 month (P ＞ 0.05).The ratio of patients with blood pressure decrease ≥ 10 mm Hg,new second degree atrioventricular block in observation group were 15.9％ and 20.5％,higher than that in control group (2.3％ and 15.9％ ; x2 =4.950,7.221 ; P =0.026,0.007).The adverse reaction was transient.Conclusion The intracoronary administration of tirofiban combined high-dose adenosine during PCI in patients with STEMI plays an effective role on improvement of myocardial perfusion.

Objective To study the changes of resting-state brain activity in knee osteoarthritis(KOA)patients with chronic pain.Methods The data of 21 KOA patients (KOA group) and 21 healthy controls (HC group) who underwent standard resting-state fMRI scan were analyzed with regional homogeneity (ReHo) method to observe the changes in the patients in contrast to the controls.Results Compared to HC group,patients of the KOA group showed ReHo changes in bilateral frontal lobe,bilateral parietal lobe,bilateral temporal lobe,bilateral cerebellum,limbic system and default-mode network.Conclusion Patients with chronic pain demonstrate abnormal neuron activities in the brain regions, and control loops not only related with pain but also related with emotive function disorder and cognitive impairment.

ObjectiveTo investigate the effects of oxidized low density lipoprotein (oxLDL) on autophagy and its effect on Akt/mTOR/p70S6K signaling pathway in human umbilical vein endothelial cells (HUVECs).MethodsThe cultured HUVECs were divided into either an oxLDL or a control group, and treated with 100 μg/ml oxLDL and equal volume phosphate buffer solution respectively.The cells were collected after 6 h and 12 h.Transmission electron microscopy was used to observe the autophagosome.Real-time fluorescence quantitative polymerase chain reaction was used to detect expression levels of microtubule associated protein 1 light chain 3 (LC3) and p62 mRNA.Western blot was used to detect the expression levels of LC3, p62, P-Akt/Akt, P-mTOR/mTOR, and p-p70S6K/p70S6K.Results Compared with the control group, the number of intracellular autophagosome increased obviously (P<0.05), LC3 mRNA and protein expression levels increased significantly (all P<0.05), and p62 mRNA and protein expression levels decreased significantly (all P<0.05) in the oxLDL group.In addition, the phosphorylated protein expression levels of Akt, mTOR and p70S6K in the oxLDL group were significantly decreased than those in the control group (all P<0.01).However, total protein levels of Akt, mTOR, and p70S6K were not significantly different between the oxLDL group and the control group.Conclusion oxLDL may induce the autophagy of HUVECs via inhibiting the Akt/mTOR/p70S6K signaling pathway.
