Objective To compare the efficacy in patients with severe pancreatitis treated by minimally invasive surgery and open surgery. Methods Seventy-three cases of patients with severe pancreatitis which were treated in our hospital between June 2011 and June 2015 were divided into group A (n = 37) and group B(n =36). Group A were treated by minimally invasive surgery while group B by open surgery. The perioperative stress reactions , postoperative inflammatory reactions , incidence of complications and mortality were compared between the two groups. Results The proportion of patients with perioperative (0+1) level pain in group A (70.3%) was significantly higher than that in group B (44.4%) (P < 0.05). Seventy-two hours after surgery, the CRP, TNF-α and IL-6 in group A were lower than those before surgery and those in group B while APN in group A was higher than that before surgery and that in group B (P < 0.05). The incidence of pulmonary infection and mortality in group A (27.0%, 5.4%) were lower than those in group B (50.0%, 22.2%) (P < 0.05). Conclusions Minimally invasive surgery in the treatment of severe pancreatitis has slight trauma. The postoperative pain is mild and complications are fewer , and the mortality is low.

Objective:To improve the accuracy of the rotary manipulations of the neck in the treatment of neck pain, according to subjective and objective clinical findings. Methods: Two groups of 60 outpatients diagnosed with neck pain were suited to the manipulation and each group was 30 cases. The diagnosis of neck pain was made with conventional clinical evaluation, including history, palpation examinations, CT scan and X-ray. Group A received a manipulation of obliquely pulling the neck. While group B received manipulation of pulling the rotated and located neck. Subjects received a maximum of 10 treatments over a 3-week treatment period. Both treatment groups were assessed with subjective (cervicodynia, neck discomfort, upper limb numbness, vertigo and tinnitus) and objective (cracking sounds). The cracking sounds during two of the manipu1ations were recorded by a microphone positioned at both sides of the neck. The sounds were compared in patients of two groups. Statistical analysis was conducted with a one-factor within-subjects analysis of variance tests and descriptive statistic. Results: Analysis of the subjective indicated that the cases with upper limb numbness were reduced from 12 to 6 in group 2, while the cases with vertigo and tinnitus were reduced from 13 to 4 in group 1. Analysis of the objective indicated two kinds of neck rotary manipulations act not only on the rotary-side facet joints, but on the opposite to the rotary side on1y in a few cases. The results showed that manipulation of pulling the rotated and located neck has a small action range and centralized action points, while manipulation of obliquely pulling the neck has many action segments and discentra1ized action points. Conclusion: It was concluded that the rotary manipu1ations act mainly on the rotary side, not on the opposite, and that manipulation of obliquely pulling the neck has a wider action range and a better therapeutic effect on cervical upper-segment lesions, while manipulation of pulling the rotated and located neck has a limited action range and is suitable for cervical lower-segment lesions. There were some relations between the joint sounds during the manipulation and clinical curative effect.

In terms of the characteristic of exonuclease I that can selectively catalyze the degradation of single-stranded DNA, we report a new sensitive electrochemical biosensor for the detection of breast cancer cells by using the aptamers of MUC1 that is overexpressed on the surface of MCF-7 cells. Because the binding of aptamer and MUC1 that is over-expressed on the surface of breast cancer cell MCF-7 can prevent its hybridization with the complementary probe DNA, the unhybridized single-stranded probe DNA that is immobilized on the electrode surface will be selectively digested by Exonuclease I and result in the removal of the signal molecule methylene blue. Therefore, by tracing the changes in electrochemical responses, the biosensor can be used to sensitively detect MCF-7 cells in a linear range from 103 to 106 cell/mL with a detection limit of 330 cell/mL, and easily distinguish the control islet β cells with high specificity.

BACKGROUND: Although hand urgical doctors have drawn the attentions to carpal diseases mainly manifesting as carpalinstability, it is still expected to carry on the researches on biomechanical properties of Chinese carpal ligaments. OBJECTIVE: To understand the biomechanical properties of partial carpal ligaments so as to provide experimental evidence for the development ofclinical hand surgery. DESIGN: A simple specimen study.SETTING:Department of Orthopaedics,Kunming General Hospital of Chengdu Military Area Command of Chinese PLA,and Institute of Clinical Anatomy, First Military Medical University of Chinese PLA.PARTICIPANTS: Sixteen fresh specimens from Chinese adult wrists were obtained from the Departmentof Anatomy, First MilitaryMedical University of Chinese PLA and the experiment was performed in the Laboratory of Biomechanics. INTERVENTIONS:The partial carpalligaments were stretched till fragmentation of ligaments by using the SWD-10materialtesting machine, at the rated velocity of 5 mm per minute so as to determine the biomechanical properties of carpal ligaments. MAIN OUTCOME MEASURES:The tolerated maximum tension and rigidity during fragmentation of radioscaphoid ligament,radioscaphocapitate (RSC) ligament, radiolunate ligament, ulnolunate (UL) ligament, ulnotriquetral(UT) ligament,ulnar bursa,scapholunate interosseous(SLI) ligament,and lunotriquetral interosseous(LTI) ligament. RESULTS: Among the ligaments attached between distal radioulnar bone and carpal bone, the maximum tension and rigidity of UL ligament were the strongest, (219.2 ±55.4) N and (65.5 ± 19.6) N/mm2, of UT ligament and ulnar bursa were the weakest, (54.0 ±25.5) N, (17.8 ± 6.0) N/mm2and (58.7 ± 17.6) N, (13.4 ±4.7) N/mm2 respectively, of SLI ligament was stronger, (286. 1 ±90.8) N, (95.5 ±40.0) N/mm2, and of LTI ligament were more stronger, (375.3 ± 52.6)N, (179.0 ± 39.0 N/mm2.CONCLUSION: Among carpal ligaments, the maximum tension and rigidity of proximal row of intercarpal ligaments were stronger than those of the ligaments attached between distal radioulnar bone and carpal bone. Of proximal row of intercarpal ligaments,the maximum tension and rigidity of LTI ligament were stronger than those of SLI ligament. Of the ligaments attached between distal radioulnar bone and carpal bone,the maximum tension and rigidity of UL ligament were the strongest.

ObjectiveTo investigate the biological significance and mechanism of VEGF-C in esophageal tumor development,and correlation of CNTN-1 level with VEGF-C.MethodsThe expression of VEGF-C and its receptors in esophageal squamous cancer cell (ESCC) and in corresponding noncancerous esophageal tissue specimens were detected by real-tithe PCR.Esophageal squamous cancer cell line TE-1 was transinfected by VEGF-C overexpression and gene silencing vectors,respectively,and the relative amount of C/EBP bound to CNTN-1 promoter was determined by quantitative ChIP,to explore the possibility that VEGF-C was involved in development of esophageal cancer through mediating transcription of CNTN-1.ResultsThe mRNA levels of VEGF-C was significantly higher in ESCC than in normal esophageal tissues.VEGF-C expression was significantly increased in VEGF-C-overexpressing TE-1 cells compared to untransfected cells (mock).Cells transfected with either of the VEGF-C targeting shRNA vectors,shRNA-1 and shRNA-2,showed reduced VEGF-C transcripts (P ＜ 0.01 ).Expression levels of VEGF-C and CNTN-1 mRNA correlated significantly with each other.The binding site of C/EBP in CNTN-1 was detected by ChIP,and the relative amount of C/EBP binding to CNTN-1 promoter was significantly increased in TE-1 after transfecting by VEGF-C overexpression vector ( P ＜ 0.05).ConclusionVEGF-C and its receptor are highly expressed in esophageal cancer tissues,which may be associated with ESCC carcinogenesis and development.VEGF-C may influence on growth and migration in TE-1 cells through CNTN-1.
