Objective To study the role of hematopoietic growth factor(HGF)of placenta chorionic villus in fetal hematopoiesis during embryo ontogeny by observation of the appearance time and the content changes with the fetal growth, which was compared with HGF in cord blood. Methods Thirty embryo villus (2 g each) and 30 cord blood (2 mL each) were collected separately from early pregnant stage(6- 8 weeks), middle pregnant stage(16-22 weeks)and late pregnant stage (37-42 weeks). The levels of HGF were detected by enzyme - linked immunosorbent assay. Results HGF were produced on the early pregnant stage and the content of FL-T3,IL-3 increased gradually.There were significantly differences at different stages(P

Objective To determine in vitro drug susceptibility to five antifungal agents of clinical Cryptococcus neoformans strains isolated from different areas of China in recent ten years. Methods Eighty clinical isolates of Cryptococcus neoformans were isolated from Shanghai, Guangdong, Fujian, Beijing and some other areas of China from 1998 to 2007. The minimal inhibitory concentrations (MIC) of the isolates to five antifungal agents, including amphotericin B, fluconazole, flucytosine, itraconazole and voriconazole, were determined using broth microdilution procedure (document M27-A2) recommended by the Clinical and Laboratory Standards Institute (CLSI). Kruskal-Wallis rank sum test was employed for the statistical analysis. Results The MIC50 of the Cryptococcus neoforrnans isolates tested for amphotericin B, fluconazole, flucytosine, itraconazole and voriconazole were 0.5, 4, 2, 0.25 and ≤0.031 3 mg/L, respectively; and the MIC<,90> of the isolates tested for the above antifungal agents were 1, 8, 4, 0.5 and 0.062 5 mg/L, respectively. Among the tested isolates, 3 (3.8 %) were resistant to flucytosine, 4 (5.0 %) were resistant to itraconazole. All isolates were susceptible to amphotericin B and voriconazole. There was no significant difference in MIC of the strains isolated from any particular years to the five agents (χ2=0.500,2.687,2.211, 2.660,0.677,P>0.05). Conclusions The Cryptococcusneoformans isolates are highly susceptible to the five antifungal agents, while a few strains are resistant to flucytosine or itraconazole. The drug susceptibilities of the strains isolated from particular years are similar.

OBJECTIVETo compare the difference in clinical efficacy on children attention deficit hyperactivity disorder (ADHD) between the combined therapy of scalp acupuncture and EGG biofeedback and the simple EEG biofeedback therapy so as to search the better therapeutic method for ADHD.

METHODSOne hundred patients were randomized into an observation group and a control group, 50 cases in each one. In the control group, the simple EEG biofeedback therapy was adopted. In the observation group, on the basis of biofeedback therapy, scalp acupuncture was added and applied to Dingzhongxian (MS 5), Dingpangyixian (MS 8), Baihui (GV 20), Sishencong (EX-HN 1), etc. The ten treatments made one session. After four sessions of treatment, FIQ value in Wechsler intelligence scale, CIH score in Conners children behavior questionnaire, the ratio of 0 wave and p wave in EEG, FRCQ and FAQ in the integrated visual and auditory continuous performance test (IVA-CPT) and clinical comprehensive efficacy were observed before and after treatment in the two groups separately.

RESULTSThree cases were dropped out in the observation group and 2 cases were out in the control group. In the two groups, FIQ, FRCQ and FAQ were all increased after treatment (P < 0.01, P < 0.05); the increases in the observation group were much more significant than those in the control group after treatment (all P < 0.05). In the two groups, CIH score and the ratio of 0 wave and p wave were all reduced after treatment (P < 0.01, P < 0.05); the reduction in the observation group were much more apparent as compared with those in the control group (both P< 0.05). The total effective rate was 91.5% (43/47) in the observation group and better than 83. 3% (40/48, P < 0.01) in the control group.

CONCLUSIONThe combined therapy of scalp acupuncture and EEG biofeedback achieves the superior efficacy on children ADHD as compared with the simple biofeedback therapy. This combined therapy rapidly relieves the essential symptoms of ADHD and improves EEG waveform in children patients. Importantly, this therapy obtains and consolidates the significant efficacy.

OBJECTIVETo investigate a new operation of breast reduction for gynecomastia.

METHODSIn the past 5 years we treated 42 cases (80 sites) of gynecomastia with the double-ring incision, a supra-lateral derma-mammary pedicle of the nipple and areola and the tumescent technique.

RESULTSThe tumescent anesthesia was effective. The operation was easily performed with slight injury and less bleeding. It was safe and the patients recovered quickly. 100 to 500 grams tissue was resected from one breast. There have been no severe postoperative complications, such as nipple or areola necrosis. Follow-up from 3 to 48 months showed satisfactory results except that there was mild scar hypertrophy on the incision around the areola.

CONCLUSIONSThe new operation for gynecomastia with the double-ring incision, a supra-lateral derma-mammary pedicle of the nipple and areola, and the tumescent anesthesia is a good, reliable and convenient technique.

[ABSTRACT]AIM:ToinvestigatetheeffectofimmunosuppressantFK506onserumglucoseinratsandtoex-plore its mechanism .METHODS: Sprague-Dawley rats ( n =12 ) were randomly divided into drug group and normal group.The rats in drug group were intraperitoneally injected with FK 506 at dose of 1 mg· kg-1 · d-1 and the rats in nor-mal group received saline (1 mL· kg-1 · d-1 , ip) for 14 d.The fasting weight and fasting glucose were regularly meas-ured every 2 d.Visceral fat was isolated from the rats at the end of experiment .The mRNA expression of adiponectin , lep-tin, visfatin, resistin, retinol-binding protein 4 ( RBP4) and peroxisome proliferator-activated receptors γ( PPAR-γ) was determined by real-time fluorescence quantitative PCR .The protein expression of PPAR-γand adiponectin was measured by Western blotting .RESULTS:Compared with normal group , the concentration of fasting blood glucose in model group was significantly increased from the 10th day (P<0.05).At day 14, the fasting blood glucose of the model group increased from (5.10 ±0.62) mmol/L to (7.73 ±0.73) mmol/L.No significant change of blood glucose in normal group between the 10th day and the 14th day [from (4.66 ±0.32) mmol/L to (5.80 ±0.10) mmol/L] was observed.Compared with normal group , the mRNA expression of PPAR-γ, adiponectin and leptin in the adipose tissue of model group was signifi-cantly decreased ( P <0.01 ) , whereas the expression of visfatin , resistin and RBP4 was significantly increased ( P <0.05).Compared with normal group, the expression of PPAR-γand adiponectin in model group was decreased (P <0.01).CONCLUSION:FK506 may decrease the expression of PPAR-γto change the expression of adipocytokines and induce hyperglycemia in rats .

OBJECTIVETo study whether the rates of pregnancy and implantation decline in repeated IVF/ICSI cycles and whether the decline is associated with the availability of embryo cryopreservation.

METHODSWe retrospectively analyzed the pregnancy and implantation rates of 1,033 IVF/ICSI cycles accomplished in our center to determine the association of the clinical outcomes with the availability of embryo cryopreservation.

RESULTSThe rates of pregnancy and implantation declined slightly in the cycles with embryo cryopreservation (43% vs 43%, P > 0.05; 29% vs 24% , P > 0.05), but significantly in the repeated IVF/ICSI cycles without embryo cryopreservation (43% vs 35%, 43% vs 22% , P < 0.05; 29% vs 23% , 29% vs 16% , P < 0.05).

CONCLUSIONThe rates of pregnancy and implantation remain similar in the following cycles for those with embryo cryopreservation in the first IVF/ICSI cycles, but decline significantly in the repeated IVF/ICSI cycles for those without.

OBJECTIVETo investigate the intensity changes of different thickness ratios of Empress II glass ceramic and GI- II glass-infiltrated alumina ceramic before and after Hertzian contact cyclic fatigue.

METHODSDisk-shaped specimens of different thickness ratios of Empress II glass ceramic and GI-II glass-infiltrated alumina ceramic were respectively fabricated. Hertzian contact technique was imposed on the specimens. Critical loads of the specimens before and after 10(5) cycles loading were recorded.

RESULTSThe average values of critical loads of all specimens reduced significantly after cycles loading (P < 0.05), and critical loads declined with diminishing thickness of the core ceramic. The critical load of GI-II glass-infiltrated alumina ceramic was significantly higher than Empress II glass ceramic before and after cycle loading(P < 0.05).

CONCLUSIONCycle loading can reduce the strengths of the two kinds of dental ceramic, and the latter is better than the former in the resistance to fracture and cyclic fatigue. Critical loads of the two kinds of dental ceramic are mainly influenced by the core ceramic's strength and thickness.

OBJECTIVETo observe the effect of the crude extracts of Dan-shen root and San-qi of different proportion on platelet aggregation and adhesion in normal rabbits.

METHODWith rabbits, ig. (4d, exsanguinated via carotid artery, percentage of platelet aggregation and adhesion was measured.

RESULT AND CONCLUSIONAspirin (4.4 mg/Kg) could markedly inhibit platelet aggregation and adhesion in normal rabbit. The proportions of Dan-shen root/San-qi (10:0, 10:1, 10:3, 10:6, 1:10) could markedly inhibit platelet aggregation, among which 10:3 was the best. San-qi alone had little effect on aggregation. The proportions of Dan-shen root/San-qi (10:3, 10:6, 0:10) could markedly inhibit platelet adhesion, among which 0:10 was the best, and the proportions(10:0, 10:1, 1:10) had little effect.
