Objective To determine the dietary nutritional status of rural residents in Midwestern Shandong Province,in order to improve the dietary pattern and health status of them.Method 11 987 residents,from 10 273 households,were included in this study by multi-stage randomized cluster sampling in 8 counties located in Midwestern Shandong Province.Questionnaire of Food Frequency (QFF) was applied to collect the information about the amount and frequency of food consumed by the subjects in the past year.Results The average intake of cereal,vegetable,fruit,meat,egg,milk,bean,oil and salt per reference man per day was 553.9 g,310.6 g,58.2 g, 36.3 g,50.1 g,16.7 g,34.4 g,44.8 g and 12.3 g,respectively.The average intake of energy,carbohydrate,protein,fat and dietary fiber per reference man per day was 12 095.6 kJ,451.8 g,85.6 g,78.8 g and 18.7 g as well Cereal food provides 66.1% of total energy; however,the meat provides only 6.6% of that.Carbohydrate,protein and fat amount to around 63.2%,12.0% and 24.8% of total energy, respectively.24.0% of fat intake was from animal food,while 76% of that was from vegetable food.Conclusions The intake of energy, protein,fat was sufficient for these subjects;however,the intake of vegetable,fruit,bean and meat was lower than the dietary reference intake.Moreover,oil and salt intake in these subjects was much higher than Chinese Recommended Nutrient Intakes.Thus,the amelioration of dietary pattern in rural residents will be an important task for nutrition workers in rural area of Midwestern part of Shandong Province in the future.

Literatures on pain intervention with transcutaneous electrical acupoint stimulation (TEAS) were collected by searching the databases both in Chinese and English, and summarized to understand the research progress of TEAS effects on pain mediators in recent years. This will provide a more objective and scientific theoretical basis for clinical practice of TEAS to treat pain syndrome, thus promoting the clinical application of TEAS. Our literature analysis indicated that TEAS effectively regulated the release levels of various pain factors such as prostaglandin, 5-hydroxytryptamine, interleukins, substance P and tumor necrosis factor-α to achieve the analgesic effects by affecting the conduction pathways. TEAS is a safe, non-invasive and effective treatment for pain syndrome. However, further research is necessary due to the lack of rigor of the current clinical trial design.

OBJECTIVETo improve the X-ray diagnosis of cervical spondylosis of vertebral artery type (VCS).

METHODSA blinded design research. The X-ray signs both 60 patients with VCS and 60 patients with cervical spondylotic radiculopathy were collected from January 2011 to November 2012. There were 36 males and 84 females, aged from 25 to 65 years old with an average of (48.4 ± 12.3) years old. Cervical curvature, atlanto-occipital joint angle, atlanto-axial joint angle, C2/C3 joint angle and lower cervical instability condition and segmental distribution were measured and recorded by X-rays. These data were analyzed and compared between the two groups after unblended. Combined with clinical manifestations,the X-ray imaging features of VCS were further analyzed.

RESULTSThere was significant difference in cervical curvature between two groups in anteflexion X-ray films (P < 0.05). There was significant difference in extension degree of atlanto-occipital joint angle between two groups (P < 0.01). There was significant difference in atlanto-axial joint angle between two groups in lateral X-ray films (P< 0.05). There was significant.difference in anteflexion degree of atlanto-axial joint angle between two groups (P < 0.05). There was no significant difference in C2/C3 joint angle between two groups. There was no significant difference in the lower cervical instability condition and segmental distribution between two groups. In VCS group, the mild and moderate dizziness was main symptom, flexion and extension activities of neck was most common cause in the dizziness; and always accompanied with headache; tenderness mostly concentrated in the upper cervical area.

CONCLUSIONBoth X-ray signs and clinical manifestations can prompt the abnormalities of the upper cervical structure or function in patients with VCS. Anteflexion activities of neck observed by functional position of X-ray films should be emphasized in diagnosis of VCS.

OBJECTIVETo isolate, identify and culture human spermatogonial stem cells (SSC) and then obtain purified and enriched human SSCs for research and application.

METHODSWe detected the expression of CD90 in the human testis using the immunofluorescence technique and isolated human testicular spermatogenic cells by two-step enzymatic digestion, followed by differential plating and magnetic-activated cell sorting (MACS) with CD90 as an SSC marker. Then we identified the isolated CD90-positive spermatogenic cells by RT-PCR and immunocytochemistry, and meanwhile cocultured them with Sertoli cells in SG medium in vitro.

RESULTSThe isolated CD90-positive cells showed a relatively homogeneous characteristic in size and morphology and expressed the genes specific for human SSCs, with high expressions (90.5%) of GFRA1, GPR125, and UCHL1. After coculture with Sertoli cells in the SG medium for 2 weeks, the isolated CD90-positive cells maintained a good activity.

CONCLUSIONCD90 can be regarded as a speci- fic marker for human SSCs and used to obtain highly enriched human SSCs by differential plating and MACS. Furthermore, the isolated human SSCs can be cultured in SG medium in vitro.

OBJECTIVESTo determine the expression of nitric oxide synthase (NOS) in testis and to investigate the effects of NO on the reproductive function of testis.

METHODSTestes of adult male Sprague-Dawley rats were fixed in 4% paraformaldehyde. The paraffin sections were made as routine. Immunohistochemical ABC method was used to observe the localization of NOS.

RESULTSEndothelia NOS (eNOS), neuronal NOS (nNOS) and inductive NOS (iNOS) were all expressed in Leydig cells. Only eNOS was expressed in peritubular myoid cells, endothelial and smooth muscle cells of blood vessel, while only nNOS expressed in tunica adventitia of testicular blood vessels. The reactive substance distributes in cytoplasm with negative nuclei. Immunoreactivity for eNOS, nNOS and iNOS in all spermatogenic cells was negative.

CONCLUSIONSThree kinds of NOS were all expressed in testis and the distribution of different NOS had a little difference.
