Objective To report the surgical technique and preliminary clinical results of bilateral decompression under microscope via unilateral approach for the treatment of lumbar stenosis. Methods Sixteen eases of lumbar stenosis were treated in our institute. For the surgical treatment, only one side paraspinous muscle was dissected. The upper and lower margins of the adjacent laminae were drilled, and the underlying ligament flavum was exposed. By changing the direction of the microscopy, the base of the spinous process and the internal side of the contralateral laminae were also drilled off till the lateral recess. Finally, decompression of the spinal canal was achieved by removing the ligament llavum. Results Follow-up ranged from 6 to 47 months. Intermittent claudication was totally relieved in 14 out of 16 cases, and markedly relieved in 2 cases. Back pain was relieved totally in 6 cases, marked improved in 8 cases, not change in 2 cases. Pain was significantly relieved in all 5 cases with sciatica, among them, diseetomy had to be performed in 3 cases. During follow-up, there was no symptom recurrence, and dynamic X ray did not show lumbar in-stability. Conclusion Bilateral decompression under microscope via unilateral approach for the treatment of lumbar stenosis is minimally invasive surgery, the effect of the operation is good. The technique has little in-fluence on spinal stability.

Objective To investigate the correlation of serum ereatine kinase iseenzyme-MB (CK-MB) and recent cardiac events(30 days, 180 days) and late cardiac events (360 days) in patients with acute coronary syndrome (ACS). Methods Serum creatine kinase (CK) and CK-MB in 168 patients with ACS were measured, and these patients were divided into four groups according to the levels of CK and CK-MB. The occurrence of cardiac events analysis of CK and CK-MB was followed up for 30, 180 and 360 days and the relationship between the occurrence of cardiac events and the levels of CK and CK-MB were studied. Results There was statistical correlation between increased CK-MB and abnormal ECG Q wave, ST segment change (P< 0.05), 168 patients had followed up 30, 180 and 360 days, in which cardiac events happened in 57 common patients (64 examples), 27 examples (16.1%) happened in the recent cardiac event, and 37 examples(22.0%) happened in the late cardiac event. The cardiac event and CK-MB elevation had statistical correlation (P<0.05). Conclusion ACS patients with increased CK-MB levels prompt a poor prognosis, and could be an independent indicator of recent and late cardiac events in patients with ACS.

Objective: To compare the similarities and differences of teeth movement at different time points after distraction osteogenesis, and to explore the best time point of teeth movement after distraction osteogenesis. Methods: The experiment was carried out on 8 beagle dogs. Group I: started teeth movement at the second week after distraction osteogenesis. Group Ⅱ: started teeth movement at the sixth week after distraction osteogenesis. Analyzed the root, periodontal ligament and alveolar bone by physical measurement, X-rays and HE staining methods. Results: In the second and sixth week after distraction osteogenesis, the distance between the third and fourth premolar teeth reduced significantly(P<0.05), there was a remarkable difference between group I and group Ⅱ(P<0.05). Conclusion: Under the same force, the speed of tooth movement in the second week is faster than that in the sixth week, but periodontal absorption in the second week is more serious than that in the sixth week.

Objective To construct cDNA entry library and cDNA expression library of Armillifer agkistrodontis (A.) nymphs and make a preliminary immunoscreening for the cDNA expression library.Methods The nymphs were collected from the Kunming mice infected experimentally with A.agkistrodontis eggs and the total RNA were extracted from the nymphs using TRIzol Reagent.After purifying the mRNA,the synthesized cDNAs were cloned into the donor vector pDONR222 by BP reaction of Gateway technology and the recombinants were transformed into the DH10B cells by electroporation,the cDNA entry library was obtained.Next,the expression vector pDEST17 was ligated with entry clones by LR reaction,and the recombinants were transformed into the BL21 (DE3) cells.Hence,the cDNA expression library was constructed.Then,the expression library was immunoscreened with the mixed sera of mice infected with A.agkistrodontis,and the insertions of positive clones were sequenced.After that,the open reading frame(ORF) of positive slone sequence,the homology of the screened genes and their encoded proteins were analyzed by Finder and BLAST (basic local alignment search tool) program of National Center of Biotechnology Information(NCBI),and the discovered new genes were submitted into the GenBank.Besides,the physico-chemical properties,secondary structure and B cell epitopes of encoded proteins were also analyzed by bioinformatics software.Results The average titer and total clones of the cDNA entry library were 1.45 × 105 CFU/ml(colony-forming unit,CFU) and 1.74 × 106 CFU,respectively,and the range of fragment length of the inserted cDNA was between 0.2-4.0 kb,with an average of 1.4 kb.The total clones of cDNA expression library were 1.00 × 105 CFU,and the fragment length of the inserted cDNA was between 0.3-2.2 kb,with an average of 1.0 kb.Five positive clones,coded S1,S5,A1,D1 and F1,respectively,were obtained through preliminary immunoscreening.The sequence and homology of the five positive clones were sequenced and analyzed by BLAST program.No significant similarities were found in pentastomida species,which meant that they were all novel genes of A.agkistrodontis.The gene sequences were submitted to GenBank,with the accession number from JQ180451 to JQ180455.Also,results obtained by bioinformatics software showed that the predictive encoding proteins were all potential to be valuable recombinant diagnostic antigens.Conclusions The cDNA library of A.agkistrodontis nymphs is successfully constructed,and five new genes of A.agkistrodontis are discovered.The establishment of cDNA library and the discovery of the new genes will lay a foundation for further studying the gene functions and screening the immunodiagnostic antigens.

Objective To observe the effects of lactobacillus complex capsules in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD). Methods A hundred AECOPD patients were divided into 2 groups: the therapy group(n = 50) with conventional and lactobacillus complex capsules therapy, and the control group with conventional therapy only. Parameters before and after therapy were compared, which included length of hospital stay, arterial blood gases, dyspnea grade, respiratory function test, markers of inflammation, anorexia score, diarrhea, fungi infection, breathing rate, death rate and side-effects of lactobacillus complex capsules. Results After 7 days of treatment, the blood leukocyte count and neutrophil ratio in the therapy group were lower than that of the control group (P < 0.05). The rate of anorexia score ≤ 2 in the therapy group was higher than that of the control group (P < 0.05). There were no differences in the rest parameters among the two groups(P > 0.05). There were no side-effects, such as skin rash and diarrhea, to be observed in the therapy group. Conclusion Oral lactobacillus complex capsule can be safe, anti-infective and improve appetite in patients with AECOPD.

Objective To observe the effects of lactobacillus complex capsules in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) and different degrees anorexia. Methods 100 anorexia score 1 and 100 anorexia score 2-5 AECOPD patients were divided into 4 groups: the therapy group 1 (anorexia score 1,n = 50) and the therapy group 2 (anorexia score 2-5,n = 50) with conventional and lactobacillus complex capsules therapy, the control group 1 (anorexia score 1, n = 50) and the control group 2 (anorexia score 2-5,n = 50) with conventional therapy. Parameters were recorded, which include length of hospital stay , markers of inflammation , arterial blood gases , lung function , clinical symptoms , death rate and side-effects of lactobacillus complex capsules. Results After treatment, WBC, trophil ratio, length of hospital stay in the therapy group 2 were lower than the control group 2(P < 0.05). The PCO2 in the therapy group 1 was lower than the control group 1 (P < 0.05). There were no differences in the rest parameters between the two control groups and the two therapy groups (P > 0.05). No side-effects like rashes, diarrhea, were observed in the two therapy groups. Conclusion For anorexia patients with AECOPD, oral lactobacillus complex capsules can safely control infection and reduce length of hospital stay.
