The imbalance of Shen-yin and Shen-yang is a common pathological basis of sexual precocity and senescence. Senescence can be regarded as physiological Shen-deficiency, which is mainly the deficiency of Shen-Yang, while the essence of sexual precocity is hyperactivity of Fire due to Yin-deficiency, and deficiency of Shen-Yin is the predominance in the imbalance. The process of growth, development, maturing and aging led by Shen-qi, is mainly involving the hypothalamus-pituitary-growth hormone axis and sexual gland axis. Early initiation of these two axes appears in sexual premature children, manifesting syndrome of Fire hyperactivity due to Yin-deficiency, while in senescence, the decline of the axes appears ahead of time and manifests syndrome of Yang qi consumption. It has been shown in experimental and clinical researches that significantly good effects could be obtained by applying Chinese recipe for warmly reinforcing Shen-Yang to postpone senescence and recipe for nourishing Yin and removing Fire to inhibit sexual precocity. It also been proved by determining syndrome and speculating the damaged site according to the effects of drug that the pathologic damage of sexual precocity and senescence is sited on the hypothalamus or higher center.

OBJECTIVETo study the inhibition of berberine (BBR) against ECV-304 apoptosis induced by Staphylococcus aureus (S. aureus).

METHODSECV-304 cells were pre-treated with 128 microg/mL BBR for 2 h and then S. aureus was added (1:100). The viability of cells was detected by MTT (3-4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay. The morphological changes were observed by Hoechst 33258 staining. The protection of BBR for infected cells was detected by DNA Ladder.

RESULTSECV-304 cells' viability were not obviously affected by berberine. But S. aureus induced ECV-304 cells' viability could be significantly inhibited by pre-treatment of BBR (P < 0.05). Besides S. aureus-induced ECV-304 apoptosis could be reduced, with significantly lessened apoptotic body and unobvious DNA degradation.

CONCLUSIONBBR could significantly inhibit S. aureus induced ECV-304 apoptosis.

Peripheral nerve impairment is a common complication in surgery, which repair relates directly to the recovery of motor function and sensory function. Clinical researchers always do nerve sutrure using microsurgical technique and adjuvant treatment to improve peripheral nerve regeneration. Western medicine used usually of adjuvant drugs, such as neurotrophic factors, are limited by their defects in clinical application. Traditional Chinese medicine classifies peripheral nerve impair as paralysis and arthromyodynia, considers that it is the result of defects of meridian and vessels, QI and blood, bones and muscles. So, drugs used usually are QI invigorating herbs, blood circulation promoting herbs for unblocking collaterals, and nourishing herbs, including astragali, hedysari, ginkgo leaf, angelica, danshen root, paeoniae radix, epimedium, chuanxiong, and common basic formulas, such as Buyang Huanwu decoction, Huangqi Guizhi Wuwu decoction, Huoxue Kangyuan decoction, compound radix hedysari, etc. To be ready for further study and development, we review the traditional Chinese medicine and formulas in this article.

OBJECTIVETo observe the effects of Qiangjing Tablets (QJT) on the semen quality and Fas/FasL signaling pathway in male SD rats with infertility.

METHODSModels of infertility were made in 50 male SD rats by intragastric administration of Tripterygium (GTW) for 3 weeks, and another 20 rats were taken as blank controls. Then 40 successfully established rat models were randomly divided into four groups, model control, low-dose QJT, medium-dose QJT, and high-dose QJT, the latter three groups treated intragastrically with QJT at 58 mg, 105 mg, and 233 mg per kg of the body weight per day, respectively. After 4 weeks of medication, the rats were killed for examination of semen quality and determination of the expression of the apoptosis factor FasL in the testis tissue.

RESULTSCompared with the blank controls, the model rats showed significant decreases in sperm concentration ([71.99 ± 9.72] vs [10.94 ± 3.58] x 10⁶/ml, P < 0.01), motility ([48.95 ± 4.10] vs [9.31 ± 5.79]%, P < 0.01), and viability ( [82.06 ± 6.16] vs [24.03 ± 6.93]%, P < 0.01). In comparison with the model controls, the rats in the QJT groups exhibited remarkably increased sperm concentration, motility, and viability, more significantly in the high-dose group ([59.66 ± 4.53] x 10⁶/ml, [35.45 ± 5.21] %, and [61.97 ± 9.75]%) and medium-dose group ([40.89 ± 4.90] x 10⁶/ml, [24.41 ± 4.79]%, and [60.06 ± 10.62]%) (P < 0.05 or P < 0.01). The expression of FasL was markedly reduced in the low-, medium-, and high-dose QJT groups (0.5215 ± 0.0189, 0.5371 ± 0.0364, and 0.4556 ± 0.0215) as compared with that of the model controls (0.5989 ± 0.0448 ) (P < 0.05 or P < 0.01).

CONCLUSIONBy upregulating the Fas/FasL signaling pathway, Tripterygium glycosides may induce the apoptosis of spermatogenic cells and reduce sperm concentration, motility and viability, resulting in infertility. The Chinese medicine Qiangjing Tablets can improve the reproductive function of male rats by decreasing the expression of the apoptosis factor FasL in the testis.

OBJECTIVETo investigate the therapeutic efficacy and its influencing factors of ultrasound-guided percutaneous radiofrequency ablation (PRFA) in the treatment of liver carcinoma.

METHODSWith a temperature-controlled multi-electrode needle, ultrasound-guided PRFA was employed to treat forty-seven patients with 67 tumor nodules, with a diameter of 2.6 +/- 1.1 cm (1.0 - 5.5 cm).

RESULTSA complete ablation (CA) rate of 80.6% was achieved in the present series, with a CA rate of 91.7% in the tumors < or = 3 cm in diameter, 75.0% in tumors from 3.1 to 4.0 cm, and 14.3% in tumors > 4 cm. The CA rate was significantly greater in tumors with a temperature rising up to 70 degrees C within the initial 2 minutes at ablation as compared with that longer than 2 minutes (P < 0.05). A markedly higher CA rate was obtained in tumors with an ablation-maintaining temperature of over 80 degrees C than that between 70 degrees C and 80 degrees C (P < 0.01). All patients were followed up with a mean time of 11.3 months. The local recurrence rate was 9.3% (5/54), and 1-year survival rate was 82.1%. Eighteen patients (38.3%) had a distant recurrence.

CONCLUSIONSThe tumor size, temperature-rising time and ablation-maintaining temperature represented the important factors affecting the therapeutic efficacy of PRFA.

The aim of this study was to investigate the best method to preserve human bone marrow cells and the effectiveness of long term cryopreservation at -80 degrees C. The human bone marrow cells in 20 samples were firstly frozen by a programmed freezer or -80 degrees C refrigerator, and then were preserved in liquid nitrogen with DMSO-AuP (10% dimethylsulfonamide, 10% autologous plasma) or DMSO-HES-HuA (5% dimethylsulfonamide, 6% hydroxyethyl starch, 4% human serum albumin) as cryoprotectant for 21 to 25 years. They were thawed in 38 degrees C. The cell sample frozen in -80 degrees C refrigerator was frozen at a low frozen speed of 1 degrees C/min which was the same as the programmed freezer before -30 degrees C. Before detection the bone marrow cells were taken from liquid nitrogen and were thawed in 38 degrees C, then the suspension of bone marrow cells was prepared for detection. The cell morphology and recovery rate of erythrocytes, nucleocytes and platelets; the recovery rate of hematopoietic stem progenitors cells, as well as mesenchymal stem cells were determined. The results showed that the protective effectiveness of DMSO-HES-HuA was better than DMSO-AuP. The mature erythrocytes were destroyed lightly [(3.5 +/- 1.5)% versus (12.6 +/- 4.8)%], the hemolysis rate was lower [(3.3 +/- 1.6)% versus (23.1 +/- 5.1)%]. Osmotic fragility of erythrocytes in the former was not changed, but was dropped in the latter. The recovery rates of red cell, platelet, granulocyte-macrophage colony forming units and long term culture-initiating cells were higher in the former than that in the latter [(96.1 +/- 1.8)%, (70.0 +/- 9.5)%, (49.2 +/- 10.9)%, (54.2 +/- 13.8)% versus (76.3 +/- 5.6)%, (52.7 +/- 8.1)%, (43.5 +/- 12.3)%, (47.2 +/- 13.6)% respectively]. With each kind of cryoprotectant or frozen method, the frozen MSC could keep the original growth properties. With the same cryoprotectant and different frozen method, the cryopreservative effectiveness was not different. The influence of the cryoprotectant prescriptions and the frozen methods on the cryopreservative effectiveness was little. It is concluded that the human bone marrow cells with DMSO-AuP or DMSO-HES-HuA as cryoprotectant, frozen by a programmed freezer or -80 degrees C refrigerator, could be then preserved in liquid nitrogen for long time. When the preserving time was as long as 21 to 25 years, the morphology, the recovery rate and the activity of various kinds of cells were still good. The method of freezing by -80 degrees C refrigerator with 5% DMSO-6% HES-4% HuA and preserving in liquid nitrogen would be convenient, cheap and easily-manipulated for preservation of the human bone marrow cells.

From March 2009 to October 2009, three pediatric patients with parotid tumor were cured. Preoperative physical examination showed regional swelling in parotid area, the surface skin was in moderate reddish purple, the border was vague, and the swelling was inactive. The patients' IgE were significantly increased. B ultrasound examination demonstrated the focus was an isoecho with ringlike dark band around, which was concluded as bull's-eye sign. Magnetic resonance imaging (MRI) examination indicated a cystic mass between the skin and parotid. Preoperative diagnosis was eosinophilichyperplastic lymphogranuloma (Kimura's disease) and the granuloma was excised by operation. Pathological examination revealed the capillary vessel hyperplasia in local tissue with a plenty of eosinophils and lymphocytes infiltrating. The disease was confirmed. Although the disease is rare, the diagnosis still could be made by preoperative physical examination, laboratory and imaging examinations.

OBJECTIVETo investigate the effect of stromal cell derived factor-1alpha(SDF-1alpha) expression and its receptor CXCR4 on the biological behavior of multiple myeloma (MM) cells and on the expression of soluble intercellular adhesion molecule 1 (ICAM-1).

METHODSFACS analysis was used to study the expression of ICAM-1 (CD(54)) and CXCR4 on the surface of MM cells. Chemotaxis assay through transwell bore polycaronate and ELISA assay were employed to monitor the soluble ICAM-1 level.

RESULTS(1) Fresh MM cells expressed variable levels of functional CXCR4 [(50.4 +/- 27.3)%], which was correlated with the in vitro ability of transwell migration of MM cells [(23.6 +/- 17.2)%, P < 0.01]. (2) SDF-1alpha could up-regulate the expression of ICAM-1 on MM cells. Furthermore, the serum level of sICAM-1 was correlated with the expression of CXCR4 on MM cells.

CONCLUSIONSDF-1alpha/CXCR4 plays an important role on the biological behavior of MM cells via mediating the effect of adhesion molecules.

Objective To evaluate the sensitivity and specificity of modified Los Angeles prehospital stroke screen (MLAPSS) in the diagnosis of acute stroke. Methods Prehospital personnel and physicians in the Emergency Department of 3 hospitals were trained for appropriate use of MLAPSS. The sensitivity, specificity, positive predictive value, negative predictive value, likelihood ratios, and Youden's index of MLAPSS for diagnosis of acute stroke were evaluated in patients with ischemic stroke, transient ischemic attack and intracerebral hemorrhage. Results Of a total of 2016 patients, 531 met the screening criteria of MLAPSS, among whom 157 had a final diagnosis of acute symptomatic cerebrovascular disease, including 82 with ischemic stroke, 17 with transient ischemic attack and 58 with intracerebral hemorrhages. The sensitivity, specificity and Youden index of MLAPSS for acute stroke diagnosis were 89% (95%CI: 85, 95), 95% (95%CI: 93, 97) and 0.85 (95%CI: 0.76, 0.94), with positive and negative predicted values of 89% (95%CI: 82, 95) and 96% (95%CI: 90, 100), and positive and negative likelihood ratios of 18 and 0.11, respectively. In the 531 patients, the missed diagnosis rate was 10% and the misdiagnosis rate was 5%. The average time to complete MLAPSS screening was 4 mitt 17 s. Conclusions MLAPSS has a relatively high sensitivity in the diagnosis of acute stroke with reduced misdiagnosis rate and high levels of specificity and predictive value. With easy operation, MLAPSS allows efficient screening of patients with acute stroke.

OBJECTIVETo analyze the clinical and laboratory features of 9 cases of gammadeltaT cell lymphoma or leukemia.

METHODSFrom 2007 to 2011, 9 patients with gammadeltaT-cell lymphoma/leukemia were diagnosed in our hospital. The immunophenotype of the abnormal cells were detected by flow cytometry, clonal gene rearrangement of IgH, TCRgamma, TCRdelta by PCR, chromosome karyotype analysis by G banding, acute leukemia gene and the DNA of type 1 - 8 human herpes virus by multiple nested PCR, The gammadeltaT cells were determined by T cell with TCR gammadelta chain, the malignant gammadelta T cells by the abnormal expression of T cell antigens and the precursor malignant gammadelta T cells by the expression of CD34, TDT, CD99, CD1 a or acute leukemia genes.

RESULTSIn the 9 patients with gammadeltaT cell lymphoma leukemia, significant malignant gammadeltaT cells infiltration of bone marrow were found in 8 with blast morphology. 5 were diagnosed as T-ALL/LBL (gammadeltaT type) and 4 HSgammadelta TCL. The clonal gene rearrangement of TCRgamma and/or TCRB were detected in 6/6 patients. Patients either did not achieve complete remission(CR) after induction therapy or relapsed quickly after CR. Only 4/5 patients remained continuous CR(CCR) at 2, 2, 3,12 months respectively, after allogeneic hematopoietic stem cell transplantation (allo-HSCT), the fifth T-ALL (gammadeltaT) relapsed 1 month after allo-HSCT.

CONCLUSIONSThe incidence of gammadelta T cell lymphoma or leukemia may be higher than reported, part of them were T-ALL/LBL with poor prognoses. FCM and clonal gene rearrangement of TCRgamma and/or TCRdelta are helpful to diagnosis. Allo-HSCT may be the only curative approach.
