Objective To observe the effect of monochromatic infrared energy(MIRE)on diabetic periphe- ral neuropathy(DPN).Methods Seventy-four subjects with diabetic peripheral neuropathy who were tested by Semmes-Weinstein monofilaments(SWM)were randomized into 2 groups:a conventional management group and a conventional management plus MIRE group.Then the patients'sensory function and other DPN symptoms were evalu- ated by the SWME and the score of Michigan Neuropathy Screening Instrument.Results After treatments,there was a decrease(P＜0.01)in the number of the sites insensitive to SWME(grade 5.07),and MNSI scores were sig- nificantly decreased(P＜0.01).The MIRE management was more effective than conventional management.Con- clusion Monochromatic infrared energy is perhaps a safe,non-pharmaceutical and non-invasive method for the treat- ment of diabetic peripheral neuropathy.

0bjective: To observe the effects of parotid saliva(PARS), extraparotid saliva(EPS) and purified high molecular weight mucin(MG1) on the aggregation of streptococcus mutans . Methods: PARS, EPS and MG1 were prepared routinely and applied in the cultures of S. mutans Inbritt, S.mutans LM and S.sobrinus OMZ 176 respectively for 2 h. The aggregation of the bacteria was measured spectrophotometrically.Results: The aggregation (%) of S.mutans Inbritt, S.mutans LM and S.sobronus OMZ 176 induced by EPS was 32.80 , 57.87 and 35.46 , that by MGI 25.68, 32.77 and 24.16 , that by PARS 13.52, 22.23 and 16.00, respectively. Conclusion: The effect of MGI on the aggregation of streptoccus mutans is weaker than that of EPS and stronger than that of PARS. The aggregation may be primarily induced by mucins.

Objective To compare the advanced non -small cell lung cancer (NSCLC)patients before and after chemotherapy peripheral blood EGFR mutation status,we understand whether the chemotherapy drug impacts the EGFR mutation status of the advanced NSCLC patients,so as to improve the precision of EGFR TKIs -drug use. Methods To collect the peripheral blood of 30 cases of advanced NSCLC before chemotherapy and after chemotherapy for 6 cycles.DHPLC technique was used to detect the EGFR mutation states of EGFR exon 19 and in exon 21.Results In 30 patients,chemotherapy prior EGFR mutation positive rate was 53.3% (16 /30).After 6 cycles of chemotherapy, the EGFR mutation positive rate was 36.6% (11 /30),the consistent rate was 56.6 (17 /30)before and after chemo-therapy,inconsistent rate was 53.4% (13 /30).10 cases from positive to negative before chemotherapy,3 cases from negative into positive before chemotherapy with statistical significance (P =0.046).Six EGFR19 exons changed, change rate of 20%,8 EGFR21 exons shift changed at a rate of 26%.EGFR19,21 shift in 1 case,with no statistical significance(P =0.39,P >0.05).Conclusion (1)The late NSCLC patients before and after peripheral blood of EGFR mutation status change,so before starting the targeted therapy we must recive real -time detection of peripheral blood EGFR mutation status,so as to decide whether to choose EGFR TKIs targeted drug therapy.(2)EGFR21 exons transformation rate is higher than EGFR19 exons conversion rate,but with no statistical difference,this phenomenon may be related to EGFR19 exons patients who with EGFR mutations -TKIs treatment efficiency is higher.

From May 2012 to May 2013, 60 chronic male smokers received an intravenous infusion of dexmedetomidine 1 μg/kg (Group D, n=30) or an equal volume of normal saline (Group C, n=30) before anesthesia induction.At time of dexmedetomidine or normal saline dosing , after induction of anesthesia, 1 and 3 min after intubation, the heart rates and rate-pressure products were significantly lower in Group D than Group C ( P<0.05 ).Thus the dosing of dexmedetomidine before anesthesia induction could suppress the cardiovascular responses of endotracheal intubation in chronic smokers and avoid increasing myocardial oxygen consumption so as to protect heart functions.

Objective To understand the basic situation and existing problems of cost accounting information construction in the traditional Chinese medicine hospital. Methods We made a cross-sectional study of all traditional Chinese medicine hospitals cost accounting informatization, and then analyzed the results. Results In the survey of 1588 traditional Chinese medicine hospitals, there exists the problem with 78.65%for limited software;57.43%for not sharing between the systems;43.20%for outdated software. The occupancy rate was 81.86%for HIS system, 87.09%for the accounting software, 39.11%for cost accounting software, 5.42%for none. The proportion of hospitals was over 95% whose income data statistics to department;80% for spending data;73.05%for fixed assets depreciation cost;51.39%for amortization of intangible assets and 52.77%for medical risk fund. The proportion of hospitals was 81.49%whose data inside services statistics to medical auxiliary departments and higher than the logistics department, which was 63.85%.Conclusion The occupancy rate of cost accounting system software was limited in traditional Chinese medicine hospitals. The problems were limited cost accounting system software and unavailable information shared between the systems.

Objective To investigate the effect of electro-acupuncture on the spinal nitric oxide (NO)/cyclic guanosine monophosphate (cGMP) signal pathway in a rat model of neuropathic pain (NP). Methods Forty-eight pathogen-free male SD rats weighing 190-210 g were randomly divided into 3 groups (n = 16 each):group Ⅰ sham operation (group S); group Ⅱ group NP and group Ⅲ electro-acupuncture + NP (group E). NP was induced by chronic constrictive injury (CCI). Right sciatic nerve was exposed and 4 loose ligatures were placed on the sciatic nerve at 1 mm intervals with 4-0 chromic catgut. In group E Huantiao and Weizhong points on the operated side were stimulated with electric stimulator (frequency 2 Hz, wave length 0.6 ms, starting at a voltage of 1mA and increasing by 1 mA every 10 min) for 30 min once a day at 11-17 d after CCI. Pain threshold to mechanical and thermal nociceptive stimuli was measured before (T0 , baseline) and at 10 and 16 d after CCI (T1, T2). The animals were sacrificed at 17 d after CCI and the lumbar segment (L4-6) was removed for determination of the activities of total NO synthase (tNOS), induced and neural NOS (iNOS, nNOS) (by spectrophotometry), NO content (by nitrate reductase method) and cGMP content (by immuno-histochemistry) in the spinal cord in 8 animals and the expression of iNOS and nNOS in the dorsal horn of the spinal cord (by immuno-histochemistry) in another 8 animals in each group. Results CCI significantly decreased the mechanical and thermal pain threshold at T1 and T2 as compared with the baseline at T0 in group NP and E. Hyperalgesia induced by CCI was significantly attenuated by electro-acupuncture at T2 in group E as compared with group NP.CCI significantly increased tNOS and nNOS activities, NO and cGMP content in the spinal cord and up-regulated nNOS expression in the spinal dorsal horn. Electro-acupuncture significantly attenuated the CCI-induced increases in tNOS and nNOS activities, NO and cGMP content in the spinal cord and nNOS expression in the spinal dorsal horn. There was no significant difference in the iNOS activity among the 3 groups. Conclusion NO-cGMP signal pathway in the spinal cord is involved in the acupuncture analgesia.

Objective To characterize and quantify the CD4 +CD25 + regulatory T (Treg) cell population in peripheral blood of patients with ankylosing spondylitis (AS) and to determine the influence of treatment with tumor necrosis factor (TNF)-a inhibitors on them.Methods Peripheral blood mononuclear cells (PBMC) were isolated from 25 patients with active AS,in which 10 patients were treated with 12 weeks of etanercept,and 21 healthy subjects.CD4+CD25high T cells were analyzed using flow cytometry,and mRNA expression of FOXP3 was determined by real-time polymerase chain reaction (PCR).Proliferation of T cells to PHA was measured by WST-1 assay using depleted CD25+ cells by immunomagnetic sorting.Results There was no significant difference in the percentage of CD4+CD25high cells in peripheral blood between patients with active AS and controls (P＞0.05).However,PBMC from patients with active AS expressed reduced levels of FOXP3 mRNA (P＜0.01) which were inversely correlated with C-reactive protein (CRP)(P＜0.01).CD4+CD25+ cells in peripheral blood of both active AS patients and controls exhibited suppressive capacity on the proliferation of effector T cells in vitro (both P＜0.01).Treatment with etanereept increased significantly CD4+CD25high cells and FOXP3 mRNA expression (both P＜0.01),with negative correlations between these increases and decrease in CRP levels (P＜0.05 and P＜0.01,respectively).Conclusion In AS patients,peripheral FOXP3-expressing CD4 +CD25 + Treg cells are abnormal,and are up-regulated by etanercept treatment.This suggests a possible pathogenesis of AS and a potential mechanism for clinical efficacy of TNF-α inhibitors.
