Andrology and gynecology have a similar or the same theoretical basis in Traditional Chinese Medicine (TCM). Andrology has a history of less than 3 decades in China, while TCM gynecology has developed for over a thousand years. The development of andrology could be greatly promoted with the guidance of the theories and prescriptions of gynecology.

Objective By in vitro culture of mouse macrophage cell line RAW264. 7 and primary mouse bone marrow macrophages, the expression of Siglec-1 when stimulated by ox-LDL was observed. Meanwhile, Siglec-1 was up-regulated by M-CSF and down-regulated by small interference RNA targeting Siglec-1 ( si-RNA-Siglec-1) , and the expression of chemokines and lipid uptake ability by macrophages were observed, to explore the role of Siglec-1 on macrophages in atherosclerosis. Methods LDL was oxidized by copper. According to preliminary experiment results, ox-LDL 100 μg/ml was selected as a stimulus. There were 6 experimental groups:normal control group,ox-LDL 100 μg/ml group, ox-LDL 100 μg/ml + si-RNA 2509 2 ng/ml group,ox-LDL 100 μg/ml + si-RNA 3618 2 ng/ml group,ox-LDL 100 μg/ml + M-CSF 5 ng/ml group and ox-LDL 100 μg/ml + M-CSF 10 ng/ml group. si-RNA-Siglec-1 was transfected into macrophage to inhibit the expression of Siglec-1, whereas M-CSF 10 ng/ml or 5 ng/ml were added into the culture medium to enhance the expression of Siglec-1. Quantitative real-time polymerase chain reaction ( qRT-PCR) was used to determine the interfere efficiency of si-RNA-Siglec-1 or M-CSF. After stimulation with ox-LDL for 48 h, cell culture supernatants were collected to determine MIP-1 alpha, MCP-1 and IL-8 concentration by ELISA (n =3 for each group) to evaluate the activation of macrophages. Internalization of lipid particles by macrophages was analyzed by oil red 0 staining. Results Observed by fluorescence microscope, si-RNA-Siglec-1 could be effectively transfected into macrophages with a transfection efficiency about 90% ;PCR results showed that si-RNA 2509 and si-RNA 3618 in a concentration of 40 pmol/L had an inhibition rate of 0. 54 ±0. 11 or 0. 52 ±0. 16 vs 1. 00 ±0. 24 (control group) , t =5. 227 and 4. 992, respectively, all P < 0.01, while M-CSF 10 ng/ml could increase Siglec-1 mRNA expression approximately 4-fold (4. 16 ± 1. 25 vs 1.00 ±0. 24, t =7. 448, P<0. 01). The secretion of MCP-1, MIP-1 alpha, and MIP-2 in si-RNA3618-Siglec-1 group [(359. 28±47. 80) pg/ml, (33. 76 ± 14. 28) ng/ml and (7.87±1.55) ng/ml for MCP-1,MIP-1 alpha, and MIP-2, respectively] was significantly reduced in compare with ox-LDL 100 μg/ml group [ (577. 89 ± 35. 95 ) pg/ml, (69. 17 ± 11. 82) ng/ml and (12.28 ± 1.19) ng/ml for MCP-1, MIP-1 alpha, and MIP-2, respectively], with P value of 0.01, 0.05 and 0.01. In contrary, ox-LDL 100 μg/ml plus M-CSF 10 ng/ml group could significantly promote macrophage chemokine secretion [ (672. 89 ± 43.80) pg/ml, (101.31 ±24.17) ng/ml and (14.81 ±0.54) ng/ml for MCP-1, MIP-1 alpha, and MIP-2, respectively], with P < 0.05 compared with ox-LDL 100 μg/ml group. Meanwhile, lipid intemalization and foam cell formation was inhibited in si-RNA3618-Siglec-l group while ox-LDL 100 μg/ml plus M-CSF 10 ng/ml group could enhance the phagocytosis of ox-LDL by macrophage. Conclusions Siglec-1 may served as a potential phagocytic receptor for ox-LDL involving in macrophage uptake of lipid and turn into foam cells. Furthermore, it can active macrophages and enhance the secretion of MIP-1 alpha, MCP-1 and IL-8, attracting more macrophages and lymphocytes to the site of inflammatory plaque. Targeted inhibition of Siglec-1 reduces macrophage uptake of lipid and secretion of chemokines. Siglec-1 may possibly serve as a potential target of treatment or delay the development of atherosclerosis.

Objective To evaluate the relationship between endogenous protective mechanism of intestinal barrier injury induced by cardiopulmonary bypass ( CPB) and enteric glia cells in rats. Methods Forty-eight clean-grade adult male Sprague-Dawley rats, weighing 400-500 g, were divided into 2 groups (n=24 each) using a random number table method: sham operation group (group S) and CPB group. Rats were sacrificed at the beginning of CPB, 60 min of CPB, and 2 and 6 h after CPB, and the intestinal tissues were removed for examination of pathological changes ( by HE staining) and for determina-tion of the expression of ZO-1, occludin, glial fibrillary acidic protein ( GFAP ) and calcium-binding pro-tein ( S-100) and the positive expression of GFAP ( by immunohistochemical method) . Results Compared with group S, the expression of GFAP and S-100 was significantly up-regulated at 60 min of CPB and 2 and 6 h after CPB, the expression of ZO-1 and occludin was down-regulated (P<0. 05), the positive expres-sion of GFAP was enhanced, and the intestinal mucosal injury was marked in group CPB. Conclusion The enhanced activation of enteric glia cells may be involved in the endogenous protective mechanism of in-testinal barrier injury induced by CPB in rats.

BACKGROUND: A hand hygiene policy has been introduced by the Joint Commission International Accreditation Standards for Hospitals (JCI); the purpose of this policy is to ensure that systematic standards are continuously practiced at hospitals in order to improve the quality of medical care and the safety of patients and health care workers. This policy requires that phlebotomists wear new gloves and disinfect their hands before attending a patient to prevent nosocomial infections and to protect the phlebotomists. This study aimed to assess the responses of patients and guardians regarding the hand hygiene procedures. METHODS: Between January and February 2010, a questionnaire survey was performed at our hospital for 310 outpatients, 93 inpatients, and 189 guardians. RESULTS: In all, 70.8% of respondents answered that phlebotomists did not require considerable time to remove and wear gloves, and 69.9% responded that phlebotomists could readily detect veins even with their gloves on. Besides, 81.9% respondents thought that it was sanitarily important for phlebotomists to remove their gloves and disinfect their hands after a venipuncture, whereas only 2.8% thought that this practice caused discomfort. CONCLUSION: The patients and guardians recognized that the hand hygiene procedures were important for their own safety and encouraged their application rather than considering them uncomfortable or inappropriate. Introduction and maintenance of the hand hygiene policy of JCI would not be difficult because patients or guardians recognized its importance.

OBJECTIVETo study clinical effects of the over-articular external fixator combined with limited internal fixation for the treatment of Pilon fractures caused by high energy.

METHODSFrom September 2003 to April 2011, 36 patients with Pilon fractures caused by high energy were treated with the over-articular external fixator combined with limited internal fixator. There were 25 males and 11 females, ranging in age from 16 to 72 years old,with an average of 38 years old. The diagnoses of all patients were determined by conventional X-ray examination or three-dimensional spiral CT examination. The AOFAS scoring criteria was used to evaluate the therapeutic effects. The patients with comminuted fractures were treated with screw or Kirschner wire fixation without uncovering periost so as to enhance stability between fracture end and bone blocks,followed by the fixation with over-articular external fixators.

RESULTSAll the patients were followed up, and the duration ranged from 4 to 27 months, with an average of 13 months. Thirty-two patients got wound healing at the first stage. And the bone union duration ranged from 2 to 6 months, with a mean of 3 months. According to the AOFAS ankle-hindfoot subjective scoring standard, 13 patients got an excellent result, 20 good and 3 fair, with an score of 88.2 +/- 3.6. Twelve patients had infections at pinhole, 5 patients had pinhole pain. One patient had the fixator broken induced by over loading, who was cured after treatment. There were no complications such as nerve or vascular injuries, or osteomyelitis.

CONCLUSIONThe over-articular external fixation combined with limited internal fixation for the treatment of Pilon fractures caused by high energy is an ideal method, which has such advantages as reliable fixation, simple operation, coincidence with principles of biomechanical fixation, and benefit for fracture healing.
