Low level laser therapy (LLLT) is a therapeutic method which regulates the biological behavior of cells with light. The effects of LLLT consist of promotion of tissue repair, inhibition of inflammation, and relief of pain by promoting or inhibiting the cell proliferation, increasing or decreasing the release of some bioactive substances. Therefore, LLLT is also known as photomodulation. At present, there are many relevant experimental studies of LLLT abroad, and they are also used clinically. This article reviews the effect of LLLT on wound healing.

OBJECTIVETo investigate the association between polymorphisms at -14 bp and zinc finger protein(ZNF) sites of ATP-binding cassette transporter A1 (ABCA1) gene promotor and high density lipoprotein-cholesterol (HDL-C) level and coronary heart disease (CHD).

METHODSPolymorphisms of Bme13901 restriction site at -14 bp and an insertion/deletion site of ACCCC in variable number of tandem repeats-zinc finger protein(VNTR-ZNF) of ABCA1 gene were detected using PCR in 260 CHD patients and 220 healthy subjects from a Chinese population in Tianjin.

RESULTSCT genotype was most common in both groups with no differences found in between (P> 0.05). No differences were found in the frequencies of the rare T allele for -14 bp (P> 0.05). For the -14 bp site, subjects with CT/TT genotype had a lower serum mean concentration of HDL-C compared with those with the CC genotype (P< 0.05). Genotypic frequencies of VNTR-ZNF were 6.2% for the inserted form, 43.8% for the deleted form and 50.0% for the inserted/deleted form. No significant difference was found in the distribution of allele and genotype, or in the levels of HDL-C between the two groups (P> 0.05).

CONCLUSIONThe genotypes at -14 bp of ABCA1 gene are associated with the plasma level of HDL-C. HDL-C levels in T allele carriers were significantly lower (P< 0.05). No association was found between variations in ABCA1 VNTR-ZNF and plasma levels of HDL-C, or between the ABCA1 -14 bp and VNTR-ZNF polymorphisms and susceptibility for CHD.

Objective To explore the effect of recovery sleep on the executive function after 36 h of total sleep deprivation by event related potential technology.Methods Thirteen healthy male college students participated in two trials. At the first trial normal sleep as control was investigated. At the second trial participants experienced 36 h of sleep deprivation and then accepted 8 h recovery sleep. In each trial six Go/Nogo tests were employed to test the executive control function and the ERP data were recorded. Results There was no statistical difference in behavior and ERP results at each time point as the subjects had normal sleep. After 36 h of sleep deprivation, the behavior results were statistically significant when compared to the baseline. The amplitude and latency of Nogo-N2, Nogo-P3 on Fz electrode, the amplitude and latency of Nogo-P3 on Cz electrode showed statistical significance when compared to the baseline. After 8 h recovery sleep, the average correct reaction time and the Go correct reaction rate had statistical significance compared to 36 h value. The amplitude of Nogo-N2 and Nogo-P3 had no statistical significance compared to the baseline.However,it was of statistical significance[(-6.80 3.95)vs(-3.37 2.63)μV,(10.63±6.62)vs(5.63±5.45)μV,(9.49±7.37)vs(6.08±6.56)μV] compared to 36 h value. The latency of the recovery value of Nogo-N2 and Nogo-P3 was statistically significant[(254.14±15.55)vs(243.08±13.97)ms(382.14±41.07)vs(349.17±30.36)ms,(369.86±26.48)vs(347.48±29.24)ms]compared to the baseline.Conclusion As the time of sleep deprivation is prolonged, the executive function is impaired and the executive function is not completely recovered after 8 h recovery sleep.

OBJECTIVETo investigate the effect of mitogen Phorbol 12-myristate 13-Acetate (PMA) on CD3, CD4 and CD8 expression of human T-lymphocytes.

METHODSPeripheral blood mononuclear cells from 37 blood samples stimulated in vitro with PMA at different concentrations (2,5,10,20 and 50 ng/ml for 4 hours) and time (10 ng/ml for 2,4 and 6 hours) were analyzed by 4-color flow cytometry (FCM).

RESULTSUnder different PMA stimulation protocols,significant CD4 down-regulation was observed,which was negatively correlated with intracellular cytokine secretion (r= 0.601,P<.001), except for PMA stimulation at 10 ng/ml for 2-hours which showed no significant intracellular cytokine secretion. The expressions of CD3 and CD8 molecules after PMA activation were not significantly affected as compared with pre-activation. Among CD3 positive T lymphocytes, CD4/CD8 double-negative cells only account for 5.52%.

CONCLUSIONPMA has a significant down-regulation effect on CD4 molecules of Th cells, without altering the CD3 and CD8 expression. For quantitative analysis of Th1/Th2 variation, indirect method such as CD3(+)CD8( ) T cells can be used to define CD4(+) Th cells stimulated by PMA in the future.

OBJECTIVETo investigate the impact of omeprazole on platelet response to clopidogrel and the effect of polymorphisms of CYP2C19 on the antiplatelet effect of clopidogrel.

METHODSPlatelet aggregation (PA) was assessed before 300 mg aspirin plus 300 mg loading dose of clopidogrel and after 300 mg aspirin plus 75 mg maintenance dose of clopidogrel 7 days later in 414 patients with acute coronary syndrome who have undergone percutaneous coronary intervention (PCI). Thereafter, gastric mucosal protective drugs were given (omeprazolem 20 mg, n=224 or cimetidine 800 mg, n=190). Fourteen days later, PA was measured again. Genotypes of CYP2C19*2 were analyzed with polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP).

RESULTSAfter taken aspirin and clopidogrel, PA has decreased significantly in both groups. Compared with cimetidine, omeprazole had no significant impact on PA on 7 and 21 days post PCI. Compared with homozygotes or heterozygotes for the wild-type CYP2C19*2, patients with CYP2C19*2 AA genotype had significantly higher PA on 7 and 21 days post PCI (P<0.05).

CONCLUSIONNo attenuating effect on platelet response to clopidogrel has been observed for Omeprazole. The variant of CYP2C19*2 AA genotype is significantly associated with attenuated response to clopidogrel.

OBJECTIVETo investigate the relationship between the -629C/A polymorphism in the promoter region of the CETP gene, serum Levels, lipid metabolism, and coronary heart disease (CHD) among Tianjin Han Chinese population.

METHODSA hospital-based case-control study was conducted in Tianjin Chest Hospital from 2010 October to 2011 October. The subjects underwent angiography were divided into a case group (n = 429) and a control group (n = 275). The CETP gene promoter polymorphism at position -629 was determined by restricted fragment length polymorphism using the polymerase chain reaction (PCR-RFLP) method.The serum CETP levels was determined by enzyme-linked immunosorbent assay (ELISA) method.

RESULTS(1)The lower frequency of -629A allele in Tianjin Han Chinese population was 0.408, significantly lower than that in other domestic and foreign populations (0.479-0.701, P < 0.05). (2) Variant AA genotype showed reduced CETP levels(P > 0.05) and higher HDL-C levels (P < 0.05), compared to wild CC genotype. (3) Although there was a negative trend correlation between serum CETP and HDL-C levels, it did not reach statistical significance(P > 0.05). (4)There were significant differences in the frequencies of CETP gene -629 genotype and allele between the two groups (P < 0.001),carries with CA/AA genotype and A allele showed higher risk of CHD, OR (95%CI) values were 4.627 (3.163-6.769), 8.779 (4.799-16.059) and 3.173 (2.453-4.104) respectively. There was no relationship between CETP-629C/A polymorphism and coronary artery stenosis degree(χ(2) = 3.588, P = 0.166).

CONCLUSIONThe frequencies of CETP gene -629 genotype and allele in the Tianjin Han Chinese population was significantly different from that in Other domestic and foreign populations. Variant AA genotype, which showed reduced CETP levels and higher HDL-C levels, is paradoxically associated with increased risk of CHD. Thus, CETP gene variation may affect coronary risk apart from the level of HDL-C.

OBJECTIVETo introduce the technique of minimally invasive percutaneous pedicle screws osteosynthesis (MIPPSO) and compare the preliminary clinical outcomes of the treatment of thoraco-lumbar vertebra fracture with traditional open pedicle screws osteosynthesis (TOPSO).

METHODSUsing the "C" arm fluoroscopic guidance, the pedicle screws were put through new-designed instrumentation and inserted percutaneously with fifty cases of thoraco-lumbar vertebra fracture. Semi-Laminectomy were made in the heavy-occupation side through the incision of 4 cm. Vertebroplasty were made through pedicle of disease vertebrae. perioperative parameter and the index of image were compared with the treatment of traditional open pedicle screws osteosynthesis in other fifty cases.

RESULTSThe consumed time of operation in the MIPPSO group and the TOPSO group made no significant difference (P >0.05), but the length of incision, injury of paraspinal muscles, bleeding of operation, drain of postoperation, pain of postoperation, spending time of hospitalization were all significantly different between the two group (P <0.05). Each group compared to itself between preoperation and postoperation, the vertebral height, the height of intervertebral disk, Cobb's angle and the occupation index of vertebral canal were all significantly different (P <0.05). however compared to each other, whether preoperation or postoperation, there were not significant different in the index of image (P >0.05).

CONCLUSIONSThe technique of minimally invasive percutaneous pedicle screws osteosynthesis (MIPPSO) has the advantages of simple manipulation, safety, small trauma, less bleeding, light pain, quickly recovery and short hospitalization time.
