OBJECTIVETo investigate the effect of Inonotus obliquus polysaccharides on testicular injury induced by exposure to high power microwave (HPM) in rats.

METHODSA total of 30 male Wistar rats were randomly divided into 5 groups, i.e., the normal control group, the microwave radiation model group, the treatment group, the new microwave radiation model group, and the prevention group, 6 in each group. All rats, except those in the normal control group, were exposed to microwave at an average power density of 200 mW/cm2 for 6 min. Rats in the control group and the model group were administered with normal saline by gastrogavage, once a day. Rats in the treatment group and the prevention group were given with Inonotus obliquus polysaccharides by gastrogavage, 2 mL each time (400 mg/kg body weight), once a day. All rats were sacrificed on the 11th day.The sperm density and the rate of sperm deformity were determined. Pathological changes of testis were observed by light microscope and transmission electron microscope.

RESULTSShort-term HPM irradiation could significantly reduce the sperm density and increase the sperm deformity rate (P < 0.05). Meanwhile, obvious pathological changes of testes occurred. Compared with the two model groups, the sperm density increased and the sperm deformity rate decreased in the treatment group and the prevention group (P < 0.05). Under the light microscope, injuries of spermatogenic cells and stromal cells, as well as vascular dilatation and congestion were obviously alleviated in the treatment group and the prevention group. Mitochondrial swelling and endoplasmic reticulum expansion shown by ultrastructural observation were also significantly alleviated. Of them, injuries of spermatogenic cells and inflammation response were milder in the treatment group than in the prevention group.

CONCLUSIONSInonotus obliquus polysaccharides had significant protective effect on microwave radiation induced testicular injury. Better effect was obtained by therapeutic medication than preventive medication.

OBJECTIVETo compare the clinical efficacy in the treatment of allergic rhinitis (AR) of lung qi deficiency and cold syndrome between Jin's three-needle therapy and western medication.

METHODSSixty-six patients were randomized into an acupuncture group and a western medication group, 33 cases in each one. In the acupuncture group, acupuncture was applied at three-nose points [Yingxiang (LI 20), Shangyingxiang (EX-HN 8) and Yintang (GV 29); Cuanzhu (BL 2) was added for frontal headache] and three-back points [Dazhu (BL 11), Fengmen (BL 12) and Feishu (BL 13)], once every day. Ten treatments made one session. Two sessions of treatment were required. In the western medication group, desloratadine oral suspension was prescribed, 5 mg each time, once a day, for 20 days. The scores of the symptoms and physical signs in AR patients as well as the clinical efficacy were observed between the two groups.

RESULTSThe total effective rate was 93.9% (31/33) in the acupuncture group, which was better than 72.7% (24/33) in the western medication group (P < 0.05). After treatment, the scores of AR symptoms and physical signs as well as the total score were all reduced compared with those before treatment in the two groups (all P < 0.01). The score of every item in the acupuncture group was lower than that in the western medication group after treatment (score of symptoms: 4.70 +/- 2.07 vs 6.55 +/- 2. 69, score of physical signs: 0.85 +/- 0.67 vs 1.45 +/- +0.62, total score: 5.36 +/- 2.70 vs 8.00 +/- 2.91, all P < 0.01).

CONCLUSIONJin's three-needle therapy achieves superior efficacy on AR of lung-qi deficiency and cold syndrome, which is better than desloratadine oral suspension.

AIM To conduct a metabolic research for a better understanding of nephrogenic edema and to assess the integral efficacy of Mori Cortex in rat model.METHODS The serum creatinine,urea nitrogen,albumin and urinary protein levels in rats were detected.UPLC-QTOF-MS was used to detect the urine metabolites changes,Principal Component Analysis (PCA) and Orthogonal Partial Least Squares Discriminant Analysis (OPLS-DA)were used to screen potential biomarkers,after whose quantification,Mev software was adopted for heat map draw-ing and hierarchical cluster analysis.RESULTS The model rats manifested significantly increased levels of serum creatinine,urea nitrogen and urinary protein,decreased albumin level,and an obviously excessive amino acid metabolism as well.The 41 identified biomarkers were mainly related to disturbances in phenylalanine,pyrimidine,arginine and proline,glycine,serine and threonine,tryptophan,cysteine and methionine metabolism,and biosynthesis of pantothenic acid and coenzyme A.A reversal trend in aforementioned levels of biochemical indexes and most biomarkers due to the intervention by Mori Cortex signaled an improvement in the metabolic disorder,renal dysfunction and edema.CONCLUSION The metabolic study demonstrates the pathological status of nephrogenic edema and assesses the effect of Mori Cortex from an overall perspective,highlighting a new approach for illustrating Chinese medical syndrome and the underlying mechanism in the management of traditional Chinese medicine.

BACKGROUNDUrotensin II (UII) is a new vasoconstrictive peptide that may activate the adventitial fibroblasts. Transforming growth factor-β1 (TGF-β1) is an important factor that could induce the phenotypical transdifferentiation of adventitial fibroblasts. This study aimed to explore whether TGF-β1 is involved in UII-induced phenotypic differentiation of adventitial fibroblasts from rat aorta.

METHODSAdventitial fibroblasts were prepared by the explant culture method. TGF-β1 protein secretion from the cells was determined by enzyme-linked immunosorbent assay (ELISA). The mRNA and protein expression of α-smooth nuscle actin (α-SM-actin), the marker of phenotypic differentiation from fibroblasts to myofibroblasts, were determined using real-time quantitative RT-PCR (real-time RT-PCR) and Western blotting, respectively.

RESULTSUII stimulated the secretion of TGF-β1 in cultured adventitial fibroblasts in a time-dependent manner. The secretion reached a peak at 24 hours, was higher by 69.8% (P < 0.01), than the control group. This effect was also concentration dependent. Maximal stimulation was reached at 10(-8) mol/L of UII (P < 0.01), which was increased by 59.9%, compared with in the control group (P < 0.01). The secretion of TGF-β1 induced by UII was significantly blocked by SB-710411 (10(-7) mol/L), a specific antagonist of UII receptor. In addition, both UII (10(-8) mol/L) and TGF-β1 significantly stimulated α-SM-actin mRNA and protein expression. Moreover, the α-SM-actin induced by UII was inhibited by the specific neutralizing antibody (20 µg/ml) of TGF-β1, while the α-SM-actin expression stimulated by TGF-β1 (20 ng/ml) was inhibited by SB-710411 (10(-7) mol/L), the UII receptor antagonist.

CONCLUSIONThis study suggests that UII could induce TGF-β1 secretion in adventitial fibroblasts via UT activation, and TGF-β1 might be involved in phenotypic differentiation from adventitial fibroblasts into myofibroblasts induced by UII, and TGF-β1 signaling might be one of the important pathways by which UII is involved in vascular fibrosis.

OBJECTIVETo determine evaluate the effect of health-promoting lifestyle on the outcomes of suboptimal health status (SHS).

METHODSA prospective population cohort was conducted by consecutively enrolling 5676 college students who took routine health examination from March to May 2013. The participants were assessed for baseline health status and lifestyle and 2972 participants with SHS were followed up for 1.5 years. Exposure was defined as an unhealthy lifestyle. The health-promoting lifestyle was assessed via the Health-promoting Lifestyle Profile (HPLP-II). SHS was evaluated using the medical examination report and Sub-health Measurement Scale V1.0 (SHMS V1.0).

RESULTSAmong the 2972 students with SHS, 422 showed recovery of the healthy status at 1.5 year follow-up, 579 showed progression into disease conditions, and 1971 remained in SHS. The participants with recovered health status presented with significant increase of SHMS V1.0 scores by 8.75∓6.95 points compared to the baseline assessment (t=-2.14, P=0.000) in physiological, psychological and social dimensions; they also showed a marked improvement of HPLP-II scores by 14.73 points in 6 dimensions (t=-15.34, P=0.000). Multivariable regression analyses with adjusted demographic variables revealed a significant association between health status and health-promoting lifestyle (P<0.05). Compared with a healthy lifestyle (minimal exposure), a 'poor' lifestyle (the highest level of exposure) was associated with a 30 times higher risk of developing SHS (OR: 30.598, 95% CI: 3.928-238.331), while a 'moderate' lifestyle (a relatively high-level exposure) had a 24 times higher risk of SHS (OR: 23.988, 95%CI: 14.695-39.158), and a suboptimal lifestyle had a nearly 4 times higher risk of SHS (OR: 4.306, 95%CI: 2.767-6.702).

CONCLUSIONs SHS may evolve into either a healthy or a disease condition. A unhealthy lifestyle is the important risk factor contributing to the progression of SHS into a disease condition, suggesting the importance of intervention of unhealthy lifestyles in promoting good health.
