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.
