Clinical observation of Tiaoshen acpuncture for dry eye syndrome with yin deficiency of liver and kidney / 中国针灸

OBJECTIVE@#To compare the curative effect of Tiaoshen acupuncture combined with artificial tears and artificial tears alone for dry eye syndrome with yin deficiency of liver and kidney.@*METHODS@#A total of 70 patients of dry eye syndrome with yin deficiency of liver and kidney were randomized into an acupuncture combined with medication group (35 cases, 2 cases dropped off) and a medication group (35 cases, 3 cases dropped off). In the medication group, 0.1% sodium hyaluronate eye drop was applied, 3 times a day, 1 drop each time. On the basis of the treatment as the medication group, Tiaoshen acupuncture was applied at Shenting (GV 24), Shenmen (HT 7), Benshen (GB 13), Taixi (KI 3), Taichong (LR 3), Guangming (GB 37), Fengchi (GB 20), Tongziliao (GB 1), Yuyao (EX-HN 4) in the acupuncture combined with medication group, Tongziliao (GB 1) and Yuyao (EX-HN 4) were connect with electroacupuncture, the needles were retained for 30 min, once a day, 6 times a week. Both groups were treated for 2 weeks. Before and after treatment, the clinical symptom score, SchirmerⅠtest (SⅠT), break-up time (BUT), corneal fluorescein staining (FL) score and Hamilton anxiety scale (HAMA) score were observed in the two groups, and the clinical efficacy was compared in the two groups.@*RESULTS@#Compared before treatment, the clinical symptom scores, corneal FL and HAMA scores were decreased (P<0.05), the levels of SⅠT and BUT were increased after treatment in the two groups (P<0.05). After the treatment, the clinical symptom score, FL and HAMA scores in the acupuncture combined with medication group were lower than the medication group (P<0.05), the levels of SⅠT and BUT in the acupuncture combined with medication group were higher than the medication group (P<0.05). The total effective rate in the acupuncture combined with medication group was 90.9% (30/33), which was higher than 71.9% (23/32) in the medication group (P<0.05).@*CONCLUSION@#Tiaoshen acupuncture combined with artificial tears could promote the secretion of tears for patients of dry eye syndrome with yin deficiency of liver and kidney, repair corneal defect and prolong tear film break-up time, and alleviate anxiety state, its curative effect is better than simple artificial tears.

Oxidative foliar photo-necrosis produced by the bacteria Pseudomonas cedrina

BACKGROUND: Although bioactive metabolites capable of causing oxidative photo-necrosis in plant tissues have been identified in fungi, little is known about this type of mechanism in bacteria. These metabolites act as photosensitizers that generate reactive oxygen species (ROS) capable of causing damage to cells. In addition, these metabolites can pass into an energetically excited state when they receive some luminous stimulus, a condition in which they interact with other molecules present in the environment, such as molecular oxygen (O2), also known as triplet oxygen (3 O2), generating ROS. RESULTS: The suspension of the bacterial culture of Pseudomonas cedrina was shown to produce foliar necrosis in papaya leaves (Carica papaya L.) only in the presence of sunlight, which is evidence of photosensitizing mechanisms that generate singlet oxygen (1 O2). From the chemical study of extracts obtained from this bacteria, 3-(4-(2-carboxipropyl) phenyl) but-2-enoic acid (1) was isolated. This compound, in the presence of light and triplet oxygen (3 O2), was able to oxidize ergosterol to its peroxide, since it acted as a photosensitizer producing 1 O2, with which it was corroborated that a photosensitization reaction occurs, mechanism by which this bacterium could prove to cause oxidative foliar photo-necrosis. CONCLUSIONS: P. cedrina was able to induce oxidative foliar photo-necrosis because of its potential ability to produce photosensitizing metabolites that generate singlet oxygen in the plants it colonizes. Based on the above, it can be proposed that some bacteria can cause oxidative foliar photo-necrosis as an important mechanism in the pathogenesis of host species.

Effect of 1, 25-dihydroxy vitamin D3 combined with mechanical strain treatment on proliferation, differentiation, and expression of OPG and RANKL in osteoblastic MC3T3-E1 cells / 医用生物力学

Objective To investigate the effect of 1,25-(OH)2-vitamin D3 (VD3) or mechanical strain alone and their combined treatment on proliferation and differentiation of pre-osteoblast MC3T3-E1 cells in vitro, as well as gene and protein expression of osteoprotegerin (OPG) and receptor activator of nuclear factor-кB ligand (RANKL) in those cells. Methods MC3T3-E1 cells were treated with 10 nmol/L VD3, intermitted mechanical strain or with a combination of these two factors. Cell proliferation was assessed with flow cytometry, and alkaline phosphatase (ALP) activity was measured using a fluorometric detection kit. The mRNA expression of ALP, runt-related transcriptional factor 2 (Runx2), OPG, and RANKL genes was determined by real-time PCR. The proteins expression of Runx2, OPG, and RANKL was determined by Western blotting. ResultsVD3 inhibited the proliferation of MC3T3-E1 cells, but the mechanical strain had no effect on cell proliferation. Mechanical strain, VD3, and the combined treatment enhanced the ALP activity of MC3T3-E1 cells as well as the protein expression of Runx2. The effect of combined treatment was less pronounced than the effect of VD3 or mechanical strain alone. Mechanical strain promoted the gene and protein expression of osteoprotegerin (OPG) and increased the ratio of OPG/RANKL. However, the combination of VD3 and mechanical strain led to a decrease in ratio of OPG/RANKL. Conclusions Mechanical strain might be effective in inducing osteogenic differentiation and increasing bone formation. A joint stimulation with VD3 and strain can decrease proliferation and osteogenic differentiation and increase RANKL expression, which might affect bone remodeling. This study supplies some new data, which might be important in theoretical and clinical research of osteoporosis (OP) and other related bone diseases.

Prevalence and Characteristics of Metabolically Obese but Normal Weight and Metabolically Healthy but Obese in Middle-aged Koreans: the Chungju Metabolic Disease Cohort (CMC) Study

BACKGROUND: We attempted to determine the prevalence and characteristics of metabolically obese but normal weight (MONW) and metabolically healthy but obese (MHO) individuals in a large cohort of middle-aged Koreans. METHODS: 8,987 non-diabetic subjects were selected from the Chungju Metabolic disease Cohort Study performed in 2003-2006. MONW was defined as a body mass index (BMI) > or = 18.5 and or = 25 kg/m2 with HOMA-IR in the lowest quartile. RESULTS: The mean age of the subjects was 62.3 +/- 10.5 years (men 40.4%). The age-adjusted prevalence of MONW and MHO were 4.3% (5.3% men, 3.7% women) and 5.6% (3.6% men, 7.0% women), respectively. 14.2% of men and 12.9% of women were classified as MONW among the normal weight population, whereas 10.7% of men and 14.5% of women were classified as MHO among the obese subjects. The prevalence of prediabetes was significantly higher in the MONW group than in the MHO group (34.7 vs. 12.5%, P < 0.0001 in men; 23.1 vs. 8.8%, P < 0.0001 in women). The MONW group evidenced an equivalent risk of coronary heart disease (CHD) relative to the MHO group (10.77 +/- 0.68 vs. 10.22 +/- 0.90% in men; 7.02 +/- 0.34 vs. 7.26 +/- 0.26% in women, means +/- standard error [SE]). CONCLUSION: The subjects in the MONW group are characterized by a high risk of diabetes and CHD, despite their normal weights. Their substantial prevalence in the population emphasizes the importance of identifying subjects in the MONW group, and warrants more intensive risk management.

According to the definition of mental disability, the item that shows higher percentage than the items of cognitional ability and volitional ability is considered as the requirement for judging mental disability. RESULTS: In all of 7 major mental disorders and disease groups, the symptoms and characteristics of the disease and the range of the influence of the symptom on the case were higher in 2-4 times than the induced standard (cognitional ability and volitional ability) from the legal and academic definitions of mental disability. CONCLUSIONS: The criteria for judging normal or mental disability is the cognitional ability and volitional ability. The criteria for judging Not Guilty by Reason of Insanity and Guilty But Mentally Ill in mental disability is the symptom and characteristics of the disease and the range of the influence of the symptom on the case.

Ecological Significance and Processes in Research of the Viable but Nonculturable State in Bacteria / 微生物学通报

The viable but noncuturable (VBNC) state is a survival strategy when bacteria are exposed to en- vironment stress. The VBNC state is part of the life cycle of non-differentiating bacteria, and it has a far-reaching impact on traditional bacteriology. Cells in the VBNC state fail to grow on the routine bacterio- logical media, here its significance in human health and environment science are detailed. Cells entering the VBNC state exhibit dwarfing and a number of metabolic changes in respiration rates and macromolecular synthesis. This paper summarized the variations in DNA and protein comparing to the culturable cells. We also discussed the ability of cells to resuscitate from the VBNC state and return to an actively metabolizing and culturable form. Some new methods for monitoring the VBNC state were listed. Finally the future was suggested.

Analysis of Viable But Non-culturable State of Staphylococcus aureus / 环境与健康杂志

Objective To study the induction and detection methods of Staphylococcus aureus viable but non-culturable state (VBNC).Methods Staphylococcus aureus (ATCC13565) of 107 cfu/ml was induced by low temperature at 4 ℃,freezing at-20 ℃ and adding copper ions from 0.01 mmol/L to 0.05 mmol/L,Staphylococcus aureus was tested,and explored the resuscitation conditions by stepwise heating-heating and chemokinesis.Results Frozen 72 h at the temperature of-20 ℃ or added 0.015 mmol/L Cu2+ for 4 days of culture could induce staphylococcus aureus into the state of VBNC.Adding 0.5% tween-20 or 1% catalase for 24 h of culture could make the strain in VBNC achieve recovery.Conclusion Staphylococcus aureus can be induced into the VBNC and the recovered Staphylococcus aureus is the same as the normal bacteria in colony morphology and physiological and biochemical response in the common test medium.
