OBJECTIVETo observe the intervention of Shenkangling Decoction (SD) on the renal injury of primary nephrotic syndrome (PNS) children patients of Shen deficiency blood stasis syndrome (SDBSS) and to explore its mechanism.

METHODSTotally 65 PNS children patients were randomly assigned to the combined group (33 cases, treated by SD +Western medicine) and the Western medicine group (32 cases, treated by Western medicine). Meanwhile, 30 healthy children were recruited as the healthy control group from the medical examination center. Those in the Western medicine group were treated with prednisone (5 mg per tablet) at the daily dose of 1.5 -2.0 mg/kg till two weeks after their urine protein turned to negative. Then the dosage was reduced once daily per every other day. The therapeutic course lasted for more than 1 year. For those with no effect of prednisone or partial effect, cyclophosphamide intravenous pulse therapy was additionally applied for 2 successive days per week, a total of 6 times, or they took cyclosporine A. Patients in the combined group additionally took SD while starting treatment of prednisone. SD was decocted in water for oral dose, once daily, taken in two portions until 2 months after prednisone was discontinued. Efficacy was evaluated based on serum levels of chemotactic factor CXCL16, disintegrin metalloproteinase 10 ( ADAM10 ), disintegrin metalloproteinase 17 (ADAM17), albumin (ALB), total cholesterol (TC), and 24-h urine protein excretion (UPE) detected by ELISA before and after treatment.

RESULTSCompared with before treatment in the same group, levels of CXCL16, ADAM10, ADAM17, TC, and 24-h UPE were significantly lower in the two treatment groups (P <0. 01). Compared with the control group, levels of CXCL16, ADAM10, ADAM17, TC, and 24-h UPE significantly increased, and the serum ALB level decreased in the two treatment groups (P <0.01). Compared with the Western medicine group at the same time point, levels of CXCL16, ADAM10, ADAM17, TC, and 24-h UPE significantly decreased in the combined group. The 1 -year recurrence rate and the recurrence times decreased in the combined group (P <0.01). The complete remission rate increased in the combined group (P <0.01).

CONCLUSIONSD could effectively improve the clinical prognosis of PNS children patients possibly by reducing the release of inflammatory mediators such as CXCL16, ADAM10, and ADAM17, decreasing UPE and the TC level, and elevating the serum ALB level.

BACKGROUND: Percutaneous laser disk decompression(PLDD) is a new interventional therapy of lumbar disk herniation recently. Posterior lateral route is often employed. Puncture route was investigated by the application of anatomic methods previously. However, there are relative fewer reports regarding the observation of the route of lumbar nerve root in intervertebral plane and triangle working area from thin section anatomy and CT section anatomy.OBJECTIVE: To clarify the intervertebral route and its adjacent relationship of lumbar nerve root on thin section and CT section to provide a anatomic gist for puncture route in PLDD.DESIGN: An observational study based on corpus and normal individual.SETTING: Department of radiology of a military medical university of Chinese PLA affiliated hospital and the department of anatomy of a military medical university of Chinese PLA.PARTICIPANTS: The collection of the first Chinese visible human was completed in the Department of Anatomy(laboratory of computer medicine) the Faculty of Medicine, Third Military Medical University of Chinese PLA in October 2002. Totally 53 subjects without confirmed vertebral and intervertebral disc diseases and other diseases of the adjacent organs received CT examination and measurement in the Department of Radiology of the Third Military Medical University of Chinese PLA Affiliated Southwest Hospital between january and March 2000.INTERVENTIONS: The intervertebral route of lumbar nerve root in the first Chinese visible human was observed descriptively. The route, morphology, size, adjacent structure, and the distance between puncture line and lumbar nerve in 53 normal individuals were observed and measured by CT.MAIN OUTCOME MEASURES: To describe the intervertebral route of lumbar nerve root in the first CVH and normal individual, to measure the intervertebral length and width of lumbar nerve, and the distance between puncture line and lumbar nerve.RESULTS: The first Chinese visible human lumbar has 48 layers of intervertebral space with a thickness of each layer of 1.0 mm. The route and adjacent structure of lumbar nerve displayed in each section were clear. CT image clearly showed the intervertebral route, size and adjacent structure of lumbar nerve root.CONCLUSION: The first Chinese visible human lumbar nerve root intervertebral route is a continuous and intact thin section specimen. The intervertebral route and morphology of lumbar root nerve have great alterations. The relationship between puncture route and its adjacent lumbar nerve root, anterior articular process, ilium wing and vessels is very close.

Objective:To explore the utilization of and satisfaction at community health service between migrant and non-migrant workers in Shenzhen city. Methods: Random sampling was used and 8000 community residents in Shenzhen city were investigated, and the data was analyzed with SPSS 18. 0. Results:There was statistically signifi-cant difference on the times of seeking community health services last year between migrant workers and non-migrant workers ( P<0. 0001 ) , and the proportion of more than three times service utilization of migrant workers were greater than that of non-migrant workers. The top three elements inpluencing satisfaction at community health service between migrant and non-migrant workers were service attitude ( 73. 29% vs. 73. 46%) , technical level ( 65. 29% vs. 67. 50%), and its convenience of seeking a doctor (63. 16% vs. 64. 98%). 73. 47% of users (migrant workers:74. 16%, non-migrant workers:69. 71%) were willing to accept the system of first contact in community health in-stitutions. Conclusions:The utilization of community health service has increased since implementing the system of first contact in community health institutions. Both migrant workers and non-migrant workers were very satisfied with the community health services, and the differences on satisfaction between the two groups were not significant. It is feasible to gradually promote the system of first contact in community health institutions over China.

Objective To study the effect of infrasound on the changes of expression of NMDAR1 in hipp- ocampal cells.Methods Eighty-eight male Sprague-Dawley rats were randomized into eleven groups:control group,90 dB/1 d,7 d,14 d,21 d and 28 d infrasound exposed groups;130 dB/1 d,7 d,14 d,21 d and 28 d infra- sound exposed groups.All the animals in the test groups were put in an infrasound field with 8 Hz,90 dB or 130 dB for 2 hours daily.Immunohistochemistry methods were used to detect the changes of intracellular expression of NMDARI in hippocampal cells.Methods The expression of NMDAR1 in hippocampus after the rats were exposed to infrasound of 8 Hz,90 dB SPL showed a procedure from reducing on the 1st day to rising on the 7th and peaked on the 14th day,then to descending on 21st day and returning to the standard level on the 28th day.Exposure to infra- sound of 8 Hz,130 dB SPL induced opposite effects on the expression of NMDAR1 compared with 90 dB SPL,which showed a process of increasing,descending,reaching to the lowest,then ascending and returning to the normal.The lowest expression of NMDAR1 occurred on the 14th day in every observed hippocampal area.Conclusion 8 Hz, 90 dB/130 dB infrasound induced certain reversible reaction in the expression of NMDAR1 of hippoeampal cells in rats,which may disturb their learning and memory function.
