Investigation of morphological changes of HPS membrane caused by cecropin B through scanning electron microscopy and atomic force microscopy

Background@#Antimicrobial peptides (AMPs) have been identified as promising compounds for consideration as novel antimicrobial agents. @*Objectives@#This study analyzed the efficacy of cecropin B against Haemophilus parasuis isolates through scanning electron microscopy (SEM) and atomic force microscopy (AFM) experiments. @*Results@#Cecropin B exhibited broad inhibition activity against 15 standard Haemophilus parasuis (HPS) strains and 5 of the clinical isolates had minimum inhibition concentrations (MICs) ranging from 2 to 16 μg/mL. Microelectrophoresis and hexadecane adsorption assays indicated that the more hydrophobic and the higher the isoelectric point (IEP) of the strain, the more sensitive it was to cecropin B. Through SEM, multiple blisters of various shapes and dents on the cell surface were observed. Protrusions and leakage were detected by AFM. @*Conclusions@#Based on the results, cecropin B could inhibit HPS via a pore-forming mechanism by interacting with the cytoplasmic membrane of bacteria. Moreover, as cecropin B concentration increased, the bacteria membrane was more seriously damaged. Thus, cecropin B could be developed as an effective anti-HPS agent for use in clinical applications.

Investigation of acupuncture in improving sleep, cognitive and emotion based on attenuation of oxidative stress in prefrontal cortex in sleep-deprived rats / 针灸推拿医学（英文版）

Objective: To explore whether acupuncture can improve sleep disturbance, cognitive impairment and emotional disorders caused by sleep deprivation, and its association with the attenuation of oxidative stress injury in prefrontal cortex. Methods: Fifty-two male Sprague-Dawley rats were randomly divided into a control group (n=10), a model group (n=14), a manual acupuncture (MA) group (n=14), and a sham-MA group (n=14). All the groups were established as sleep deprivation models via the modified multiple platform method, except for the control group. Rats in both the MA group and the sham-MA group received corresponding intervention, respectively. After modeling and intervention, the four groups received three behavioral tests, namely sleep monitoring, by comprehensive lab animal monitoring system (CLAMS), Morris water maze (MWM) test and open-field test (OFT), followed by oxygen free radical level test and Western blot (WB) detection for the expression levels of Bax and Bcl-2. Results: The MA group derived more sleep time within 24 h than either the model group or the sham-MA group (both P<0.05). On MWM orientation navigation test day 1, there were no significant differences in escape latency among the control, MA and sham-MA groups (P>0.05), and the escape latency was significantly shorter in these three groups than that in the model group (all P<0.05). On test day 4, the escape latency was markedly shorter in the MA group than that in either the model group or the sham-MA group (both P<0.05); meanwhile, the MA group showed significantly better performance compared with these two groups in space probe test (both P<0.05). In OFT, compared with the control group, there was a significant decline in the horizontal movement score in the other three groups (all P<0.05), and the decrease was more significant in the model group and the sham-MA group than that in the MA group (both P<0.05). The superoxide dismutase (SOD) content was markedly higher and the malondialdehyde (MDA) content was markedly lower in the MA group than those in the model group and the sham-MA group (all P<0.05). Compared with the model group and the sham-MA group, the expression of Bax was significantly lower and the expression of Bcl-2 was significantly higher in the MA group (all P<0.05). Conclusion: MA therapy can lengthen the sleep time in sleep-deprived rats and improve learning and memory impairments induced by sleep deprivation, and the underlying mechanism may be associated with the enhancement of antioxidant capacity in the prefrontal cortex and the inhibition of hippocampal neuronal apoptosis.

Clinical effect of "head-nine-needle" therapy on tension headache / 针刺研究

OBJECTIVE: To observe the effect of the "head-nine-needle" therapy on tension headache. METHODS: A total of 150 patients with tension headache were divided into a head-nine-needle therapy group, a western medicine control group and an acupuncture control group according to the random number table, 50 cases in each one. In the head-nine-needle therapy group, the head-nine-needle therapy was adopted. In the western medicine control group, epiperisone hydrochloride tablets were prescribed for oral administration, 50 mg, three times a day as well as fluoguili hydrochloride capsules, 5 mg, once a day, taking orally before sleep. In the acupuncture control group, the routine acupuncture technique was used at Baihui (GV20), Taiyang (EX-HN5), Fengchi (GB20) and Ashi (extra), etc. The clinical effect was observed in each group. The scores of visual analogy scale (VAS) for headache severity and the scores of headache duration were assessed before and after treatment in the patients of each group. RESULTS: In comparison of the total effective rate among the groups, there was no significant difference between the head-nine-needle therapy group (48/50，96.0%) and the acupuncture control group (47/50，94.0%). The total effective rate of either of the two groups was higher than that of the western medicine control group (40/50，80.0%，P0.05). After 3 weeks and 4 weeks of treatment, the scores in the two acupuncture groups were all better than those in the western medicine control group (P<0.05). CONCLUSION: The "head-nine-needle" therapy achieves the obviously advantages in the alleviation of headache degree as compared with the simple western medicine and its effect is similar to the common acupuncture therapy in the patients with tension headache.

Effects of Decitabine Combined with Bortezomib on the Proliferation of Mantle Cell Lymphoma Cell Lines and Its Underling Mechanisms / 中国实验血液学杂志

OBJECTIVE@#To investigate the effects of decitabine combined with bortezomib on the proliferation of mantle cell lymphoma cell lines (Jeko-1 and Grante519) in vitro and explore the underlying mechanisms.@*METHODS@#Jeko-1 and Grante519 cells were treated with different concentrations of decitabine and/or bortezomib alone and their combination.The cell proliferation was determined by CCK-8 assay. the cell apoptosis were detected by flow cytometry, the mRNA and protein expression levels of genes related with the cell cycle and apoptosis were analyzed by RT-PCR and Western blot respactively.@*RESULTS@#Low dose DAC could significantly inhibit the proliferation and induce apoptosis of Jeko-1 and Grante519 cells which shows a dose-and time-dependent manner. After DAC treatment, caspase 3, BAX and PCDH8 expression levels increased, while BCL-2 and CCND1 expression levels decreased in Jeko-1 and Grante519 cells, but there was no significant difference in NF-κB expression. High dose BTZ could significantly inhibit the proliferation and induce apoptosis of Jeko-1 and Grante519 cells which shows a dose-and time-dependent manner; single drug BTZ could increase the expression level of Caspase 3 and BAX, and decrease the expression level of NF-κB, BCL-2 and CCDN1 in Jeko-1 and Grante519 cells, but there was significant difference in PCDH8 expression level. Compared with single-drug treatment group, DAC combined with BTZ significantly increased the inhibitory rate and apoptotic rate of Jeko-1 and Grante519 cells; PCDH8, Caspase 3 and BAX expression levels significantly increased, and the expression levels of NF-κB, BCL-2 and CCND1 significantly decreased in Jeko-1 and Grante519 cells.@*CONCLUSION@#The combination of DAC and BTZ has obviously synergistic effects on the growth inhibition of Jeko-1 and Grante519 cells which maybe relates with enhancing inbibitory effect on NF-κB signal pathway, down-regulating BAX expression, up-regulating BAX expression as well as increasing cospase 3 expression. This study provides a novel therapeutic approach for mantle cell lymphoma.

Research progress on Wnt3 gene polymorphism and susceptibility to non-syndromic cleft lip and palate / 医学研究生学报

Non-syndromic cleft lip with/without cleft palate (NSCL/P) is a common congenital disease worldwide, and its etiology is related to the combination of genetic and environmental factors. Although genome-wide association analysis did not involve Single Nucleotide Polymorphisms (SNPs) in Wnt genes, it has been reported that SNPs in Wnt genes are related to NSCL/P, and the study of SNPs of Wnt genes and its corresponding phenotypic effect is helpful to explain the etiological mechanism of NSCL/P. In recent years, Wnt3 gene related to NSCL/P, rs142167, rs3809857, rs9890413 and other teratopoietic single nucleotide loci are the main teratopoietic single nucleotide loci studied most, and the research conclusions on the correlation between Wnt3 gene polymorphism and NSCL/P are obviously different in different populations. This paper reviews the research progress on the correlation between Wnt3 gene polymorphism and NSCL/P.

OBJECTIVE@#To observe the effects of electroacupuncture (EA) at "Jiaji" (EX-B 2) points combined with nerve mobilization on protein and mRNA expression of RhoA in rabbits with sciatic nerve injury, and to provide theoretical basis for the treatment of peripheral nerve injury by EA at "Jiaji" (EX-B 2) points combined with nerve mobilization.@*METHODS@#A total of 180 New Zealand rabbits were randomly divided into a normal control group, a model control group, a nerve mobilization group, an EA group, an EA plus nerve mobilization group, 36 rabbits in each group. Each group was further divided into a 1-week subgroup, 2-week subgroup and 4-week subgroup, 12 rabbits in each subgroup. The sciatic nerve injury model was made by clamping method. The rabbits in the normal control group did not receive any intervention. The rabbits in the model control group was normally fed after operation. The rabbits in the nerve mobilization group were treated with nerve mobilization; the manipulation lasted for 1 s and relaxed for 5 s, 10 times per day, 6 days per week. The rabbits in the EA group were treated with EA at "Jiaji" (EX-B 2) points (L-L), once a day, 30 min each time, 6 times per week. The rabbits in the EA plus nerve mobilization group were treated with EA at "Jiaji" (EX-B 2) points, followed by nerve mobilization. The function of sciatic nerve on the injured side was evaluated by toe tension reflex and modified Tarlov score; the tissues of corresponding segments of spinal cord L-L and sciatic nerve were taken; the expression of RhoA gene was detected by real-time PCR and the expression of RhoA protein was detected by Western Blot.@*RESULTS@#① Toe tension reflex and modified Tarlov score: at 1, 2 and 4 weeks, the scores in the model control group were lower than those in the normal control group (all 0.05); at 2 weeks, the expression in the nerve mobilization group was higher than that in the EA group (all <0.01); at 4 weeks, the expression in the nerve mobilization group was lower than that in the EA group (all <0.01).@*CONCLUSION@#The nerve mobilization and EA at "Jiaji" (EX-B 2) points could both promote the repair of injured sciatic nerve, which may be related to the down-regulation of RhoA expression, and the combination of the two methods has better effects.

Anti-diabetic effects and mechanisms of action of a Chinese herbal medicine preparation JQ-Rand in diabetic KKmice

Refined-JQ (JQ-R) is a mixture of refined extracts from(Ranunculaceae),(Leguminosae) and(Caprifoliaceae), the three major herbs of JinQi-JiangTang tablet, a traditional Chinese medicine (TCM) formula. The mechanisms by which JQ-R regulates glucose metabolism and improves insulin sensitivity were studied in type 2 diabetic KKmice and insulin-resistant L6 myotubes. To investigate the mechanisms by which JQ-R improves insulin sensitivity, a model of insulin-resistant cells induced with palmitic acid (PA) was established in L6 myotubes. Glucose uptake and expression of factors involved in insulin signaling, stress, and inflammatory pathways were detected by immunoblotting. JQ-R showed beneficial effects on glucose homeostasis and insulin resistance in a euglycemic clamp experiment and decreased fasting insulin levels in diabetic KKmice. JQ-R also improved the plasma lipid profiles. JQ-R directly increased the activity of superoxide dismutase (SOD) and decreased malondialdehyde (MDA) as well as inducible nitric oxide synthase (iNOS) levels in insulin-resistant L6 cells, and elevated the insulin-stimulated glucose uptake with upregulated phosphorylation of AKT. The phosphorylation levels of nuclear factor kappa B (NF-B p65), inhibitor of NF-B (IB), c-Jun N-terminal kinase (JNK1/2) and extracellular-signal-regulated kinases (ERK1/2) were also changed after JQ-R treatment compared with the control group. Together these findings suggest that JQ-R improved glucose and lipid metabolism in diabetic KKmice. JQ-R directly enhanced insulin-stimulated glucose uptake in insulin-resistant myotubes with improved insulin signalling and inflammatory response and oxidative stress. JQ-R could be a candidate to achieve improved glucose metabolism and insulin sensitivity in type 2 diabetes mellitus.
