OBJECTIVETo observe the differences in timely effectiveness of immediate analgesia on acute migraine between electroacupuncture (EA) at shaoyang meridian points and non-meridian points.

METHODSThe randomized controlled trial method was adopted. One hundred and ten cases of acute migraine were randomized into two groups. 55 cases in each one. In the observation group, EA was applied to Fengchi (GB 20), Waiguan (TE 5), etc. In the control group. EA was applied to non-meridian points. Only one treatment was given, and the nee dies were retained for 30 min in the two groups. Separately. at 10 time points, named before acupuncture, in 5 min, 10 min. 20 min and 30 min (at the moment of needle removal), 1 h, 2 h, 4 h, 6 h and 8 h after acupuncture, the pain intensity numerical rating scale (PI-NRS) was adopted to evaluate the pain severity and the adverse reac tion was recorded.

RESULTS(1) The effective rate of imnmediate analgesia was 87. 3% (48/55) in the observation group. significantly higher than 52.7% (29/55) in the control group (P<0.01). (2) NRS of each group was re duced at each time point, from 5 min to 8 h after acupuncture (all P<0.01). (3) NRS score at 30 min after acu puncture in the control group was obviously lower than that in the observation group (P<0.05), but the scores in 2 h, 4 h, 6 h and 8 h after acupuncture in the observation group were lower apparently than those in the control group (all P<0. 01). The differences in the scores in 5 min, 10 min, 20 min and 1 h after acupuncture were not significant (all P>0. 05). (4) For the reducing amplitude of NRS score at the same time point after acupuncture, the results in 20 min, 30 min and 1 h in the control group were higher apparently than those in the observation group (all P<0. 05). But, in 2 h, 4 h, 6 h and 8 h, the results in the observation group were higher apparently than those in the control group (all F<0.05). The differences in 5 min and 10 min after acupuncture were not significant (both P>0. 05). (5) In 24 h after acupuncture, the recurrence rate of migraine was 12. 7% (7/55) in the observation group, which was lower obviously than 34. 5% (19/55) in the control group (P<0. 05). The adverse reaction was not found in the two groups.

CONCLUSIONEA at the shaoyang meridian points achieves the definite immediate analgesia effect on acute migraine and presents the time effectiveness of analgesia.

Objective To analyze the application of clinicopathological features and LEF-1 in the diagnosis of solid pseudopapillary neoplasm of the pancreas (SPN).Methods Clinical and pathological data of 227 cases who were pathologically diagnosed as pancreatic SPN at Changhai Hospital from Jan 2000 to Dec 2015 were collected and analyzed.Immunochemical assay was used to detect the expression of LEF-1 in 132 cases of SPN, and the results were compared with β-catenin, which is most commonly used for diagnosing SPN.Results 81.9% of patients with SPN were female (186/227).Mean age at the onset was 34 years.Mean tumor size was 5.4 cm.48.5% tumors were localized in the pancreatic tail, and 33% in the head.46.3% tumors were cystic and solid, 42.3% were solid, and 11.4% were cystic.There were 2 cases of lymph node metastasis (0.9%), 15 cases of vascular tumor thrombus (6.6%), 14 cases of nerve invasion (6.2%), and 13 cases of adjacent organs invasion (5.7%) based on microscopic observations.Immunochemical analysis showed that 130 of 132 cases with SPN expressed LEF-1 with strong nuclear positivity, and the positivity rate was 98.5%.But no obvious expression of LEF-1 can be seen in normal pancreatic tissue and other pancreatic tumors.The specificity was 100%.The positivity of β-catenin expression in SPN was 96.6%(144/149), and β-catenin was positively expressed in only one case of acinar cell carcinoma.Tumors were completely removed by surgery in 165 cases, and the median follow-up was 51 months.By Oct 31, 2016, 162 patients (98.2%) survived, 5 had liver metastasis, and 1 had recurrence.Conclusions SPN is predominantly encountered in young female patients, and the clinical manifestations are not specific.LEF-1 can be used as a specific marker for the diagnosis and differentiation of SPN, which is more accurate than β-catenin.

Research on novel pullulanase has major significance on the domestic industrialization of pullulanase and the breakdown of foreign monopoly. A thermophilic bacteria LM 18-11 producing thermostable pullulanase was isolated from Lunma hot springs of Yunnan province. It was identified as Anoxybacillus sp. by 16S rDNA phylogenetic analysis. Full-length pullulanase gene was cloned from Anoxybacillus sp. LM18-11. The optimum temperature of the pullulanase was between 55 and 60 degrees C with a half-life as long as 48 h at 60 degrees C; and its optimum pH was between 5.6 and 6.4. V(max) and K(m) of the pullulanase was measured as 750 U/mg and 1.47 mg/mL, which is the highest specific activity reported so far. The pullulanase crystals structure showed a typical alpha-amylase family structure. The N-terminal has a special substrate binding domain. Activity and substrate binding were decreased when the domain was deleted, the V(max) and K(m) were 324 U/mg and 1.95 mg/mL, respectively. The pullulanase was highly heterologous expressed in Bacillus subtilis by P43 promoter. The extracellular enzyme activity was 42 U/mL, which increased more than 40 times compared to the initial strain. This pullulanase has good application prospects.

To select appropriate descriptors for response of the patient-reported outcome (PRO) scale for the main symptoms of patients with chronic obstructive pulmonary disease (COPD) complicated with pulmonary heart disease.

ObjectiveTo investigate the effect of cholinesterase inhibitor on endotoxin-induced brain injury in rabbits.Methods Twenty-one healthy male rabbits were randomly assigned into three groups ( n ＝ 7each):group sham operation (group S),lipopolysaccharide (LPS) group and cholinesterase inhibitor (tacrine hydrochloride,THA) group.LPS 200 μg/kg was intracerebroventricularly injected in LPS group,LPS 200μg/kgand tacrine hydrochloride 150 μg/kg were injected in THA group,while same volume of normal saline was injected in S group.Then blood and tissue samples were collected in different groups after 4 hours.Nuclear factor-kappa B (NF-κB) p65 activity of brain tissues was determined by using Western blot analysis.Tumor necrosis factor-alpha (TNF-α) levels in plasma,cerebrospinal fluid and brain tissues were measured using enzyme linked immunosorbent assay.The brain tissue's myeloperoxidase (MPO) activity and the ratio of wet to dry weight (W/D) were also analyzed.ResultsAs compared with S group,TNF-α level in plasma,cerebrospinal fluid and brain tissues,NF-κB p65 level,MPO activity and W/D ratio increased in LPS and THA groups (P < 0.05).When compared with LPS group,TNF-α level in plasma,cerebrospinal fluid and brain tissues,NF-κB p65 level,MPO activity and W/D ratio decreased in THA group ( P < 0.05 ).ConclusionCholinesterase inhibitor can attenuate the endotoxin-induced brain injury through inhibiting local inflammatory responses.

ObjectiveFollow-up of the clinical outcome of prosthetic disc nucleus replacement on patients with lumbar intervertebral disc herniation. Methods16 patients with lumar intervertebral disc herniation were implanted prosthetic disc nucleus from June to August 2003, including 10 males and 6 females. The operation levels were at L4-5 in 10 patients and L5～S1 in 6 patients. All patients were followed up from 28 to 32 months (averaged 30 months). The contents include pain, physical examination, Short-form of McGill Pain Questionnaire investigation, Visual Analogue Scales(VAS) and Present Pain Intensity(PPI), X-ray and MRI examination, etc. ResultsAfter surgery, 16 patients experienced clinical symptom relief, the displacement of PDN in 1 case and dislocation in 1case, the height of intervertebral space becoming narrower in 5 cases and endplate subsiding in 1 case. ConclusionProsthetic disc nucleus replacement acquired satisfactory after operation, but some complication may occurre in long-term.

Results The resectability of cervical esophageal carcinoma was 100%,no case complicated with pharyngeal fistula.Swallowing function of all cases was in a good state.The overall follow-up was 1 to 7 years,among them 9 surviving,3 dead.The surviving 5 cases are over 3 years,the ongest beyond 7 years. Conclusions Gastric(enteric)-pharyngeal anastomosis is a good primarily rehabilitating method of the cervical esophageal defect after surgical treatment of cervical esophageal carcinoma.

Objective: To study the prognostic impact of chronic total occlusion (CTO) on non-infarct-related artery (non-IRA) in patients of acute ST-elevation myocardial infarction (STEMI) with emergent primary percutaneous coronary intervention (PCI).
Methods: In this prospective study, a total of 185 consecutive acute STEMI patients received early stage primary PCI in our hospital from 2010-01to 2011-06 were enrolled. The patients were divided into 2 groups:non-CTO group, n=160 and CTO group, n=25. The patients were followed-up for 1 year and the primary endpoint events included the hospitalization for angina, re-MI, heart failure or revascularization and cardiac death.
Results: ①There were more patients with diabetes and three vessel disease in CTO group than those in non-CTO group (40.0%vs 20.0%, P=0.049) and (68.0%vs 36.3%, P=0.003);LVEF in CTO group was lower than non-CTO group (40.0 ± 20.1%vs 51.3 ± 15.3%, P<0.05).②The cardiac mortalities at 6-month and 1-year followed-up period were higher in CTO group than those in non-CTO group (26.3%vs 6.1%, P=0.013) and (31.6%vs 8.4%, P=0.010);1-year primary endpoint events were higher in CTO group (52.6%vs 16.8%, P=0.001). ③Multivariate regression analysis revealed that non-IRA combining CTO (HR=3.889, 95%CI 1.239-4.206, P=0.020), cardiac shock (HR=3.229, 95%CI 2.760-3.725, P=0.012) and three vessel disease (HR=2.008, 95%CI 1.549-3.372, P=0.040) were the independent predictors for 1-year mortality in patients of acute STEMI with primary PCI.
Conclusion: Non-IRA combining CTO in STEMI patients with primary PCI are usually having poor prognosis.

Objective To summarize the clinical experience of "One-stop" hybrid procedure that performs minimally in-vasive direct coronary artery bypass ( MII)CAB ) and percutaneous coronary intervention ( PC! ) concurrently on 35 patients with multivessel coronary artery disease (CAD). Methods Between June 2007 and May 2008, 35 patients [33 men and 2women, mean age (63.5±9.2) years] with multivessel CAD ( two-vessel CAD, n = 19; three-vessel CAD, n = 16, left main coronary artery disease, n = 7 ; coronary artery lesions, 2.5 lesions per patient) underwent "one-stop" hybrid procedure. The hybrid strategy was performed as a primary MIDCAB procedure for bypassing the left internal mammary artery ( LIMA ) to the left anterior descending artery ( LAD ), simultaneously followed by PCI ( pereutaneous transluminal coronary angioplasty (PTCA) and/or stenting) on the remaining non-LAD vessels. Concomitant diseases included hypertention in 20 patients, hy-perlipemia in 12 patients, previous myocardial infarction (MI) in 10 patients, diabetes mellitus (type 2) in 9 patients, previ-ous cerebrovascular disease in 2 patients, chronic obstructive pulmonary disease (COPD) in 1 patient, renal dysfunction in 1 patient, and ostium secundum atrial septal defect in 1 patient. The left ventricular ejection fraction (LVEF) averaged 0. 62±0.07. Results There were no reexploration for bleeding, strokes, myocardial infarctions, acute renal dysfunctions, or deaths in hospetal. Of the total 35 patients, 34 patients (97.1%) were successfully treated with "one-stop" hybrid procedure, and 1 patient (2.9%) was converted to conventional coronary artery bypass grafting ( CABG ) because of dissection of one obtuse marginal branch during PCI. One of the LIMA-LAD grafts was confirmed to be anastomotic stenosis by followed coronary angiog-raphy and was corrected immediately. The patient with ostium secundum defer underwent tranesophageal echocardiography guiding transcatheter closure after LIMA-LAD anastomosis. Catheter-based interventions were carried out in 61 coronary le-sions, including PTCA in 6 lesions and implantation of 62 drug-elating stents (DES) in the rest appropriate lesions. The mean number of DES implantation was 1.8 per patient, and the average diameter and length of implanted DES were respectively ( 3.2±0.5 )mm and 37.3 mm per patient. Of the 34 patients receiving hybrid procedure, the average mechanical ventrilation time was ( 10.8±7.9) hours, and 4 ( 11. 8% ) pateints were extubated in the operating room; length of stay in the intencive care unit averaged (33.6±33.0) hours and hospital stay (9±3) days; 24 patients (70.6%) avoided transfusion require-ment. Conclusion Our findings indicate that in high-risk patients with multivessel CAD, the "one-stop" hybrid procedure by performing MIDCAB and PCI simultaneously is a feasible and safe alternative.
