OBJECTIVETo investigate the correlation of premature ejaculation (PE) with central lumber intervertebral disc herniation (CLIDH) and the pathogenesis of PE, and to search for a convenient, effective and non-invasive method for the treatment of PE.

METHODSA total of 263 selected PE patients underwent CT, and those that were found with CLIDH were randomized into a treatment group (n=180) and a control (n=60), the former treated by lumbar traction and the latter with sertraline hydrochloride tablets, both for 24 weeks. CIPE-5 scores of all the patients were analyzed, and the ejaculation latency and sexual satisfaction were recorded before and after the treatment.

RESULTSAmong the 263 PE patients, CLIDH was confirmed in 240 (91%). After the treatment, CIPE-5 scores, ejaculation latency and sexual satisfaction were markedly improved in the treatment group, with significant statistic difference from pre-treatment (P < 0.01). Significant differences were also observed between the treatment and the control groups after the treatment (P < 0.05), but not in the control group between pre- and post-treatment.

CONCLUSIONCLIDH may be one of the important causes of most "unexplainable" PE cases. And lumbar traction, non-invasive, highly effective and easily manipulable, has provided a new access to the diagnosis and treatment of the PE patients with CLIDH.

OBJECTIVETo reveal the clinical features of patients with acute arrest of hemopoiesis (AAH), and explore the dissimilarity between AAH, severe aplastic anemia (SAA) and very severe aplastic anemia (vSAA).

METHODSThe clinical and laboratory features of 23 AAH patients diagnosed and treated in our hospital from May 1993 to May 2006 were analysed retrospectively and compared to the 111 cases of SAA and vSAA patients diagnosed at anaemia therapeutic centre of the hospital from Jul 2002 to May 2006.

RESULTSTwenty-three patients accorded with the criteria for AAH, and 16 of them with the criteria for severe acute arrest of hemopoiesis (SAAH). They could spontaneously reconstitute their bone marrow hematopoiesis at a median of 17 days (range, 8-50), and had remarkable older age (median age 35.5 vs 21), positive history of other disease and taking medication. Fever as one of presenting symptom were noticed in 10 of 16 STAA patients. The laboratory results were similar with SAA or vSAA, had more frequent decreased serum albumin level and total iron binding capacity and higher CFU-GM.

CONCLUSIONSPatients with AAH often had similar clinical symptoms with SAA or vSAA. Although they were diagnosed retrospectively, identification of the pathogenesis and laboratory examination may help for the early diagnosis.

Aim To investigate the role of PPARβ and nitrative stress in human umbilical vein endothelial cells(HUVECs)injury induced by high glucose.Methods The cell viability was detected by CCK-8.The cell proliferation was detected by EdU proliferation detection kit.The protein expression level of PPARβ,eNOS,iNOS,and 3-nitrotyrosine was detected by Western blot.The content of peroxynitrite and nitric oxide(NO)was determined by peroxynitrite kit and Griess Reagent,respectively.Results Glucose(30,40,50 mmol·L-1)significantly reduced the cell viability of HUVECs in a dose-dependent manner.Glucose at 30 mmol·L-1(high glucose,HG)significantly reduced the proliferation of HUVECs,down-regulated the expression of PPARβ,eNOS at protein level and NO content,and increased iNOS,3-nitrotyrosine protein expression and peroxynitrite level.The above effects of HG were reversed by PPARβ agonist GW0742(1 μmol·L-1).Both PPARβ antagonist GSK0660(1 μmol·L-1)and NOS inhibitor L-NAME(10 μmol·L-1)blocked the protective effects of GW0742.Conclusion The down-regulation of PPARβ is involved in the injury of HUVECs induced by high glucose,which may be mediated,at least partly,by the stimulation of nitrative stress.

Chronic obstructive pulmonary disease (COPD) is a common respiratory disease with a high morbidity, disability and mortality. At the same time, COPD is always accompanied by pulmonary hypertension, pulmonary fibrosis, chronic pulmonary heart disease, right heart failure and other common serious complications. All of these cause serious financial burden for the family of patients. Airway remodeling plays an important role in the pathogenesis of COPD. It is the progressive development of airflow restriction that induces the main symptoms of COPD, such as cough, asthma and depression. Therefore, it is of great research value to explore the intervention of traditional Chinese medicine(TCM) in the development of COPD by alleviating airway remodeling. Studies have shown that multiple signaling pathways can induce progressive airway remodeling, and the therapeutic effect of TCM has been frequently confirmed by experimental studies. TCM often has a therapeutic effect on COPD through multi-target and multi-channel mediation. This paper mainly includes five signaling pathways that traditional Chinese medicine can intervene COPD airway remodeling, namely matrix metalloproteinases (MMPs)/tissue inhibitors of metalloproteinase (TIMPs), transforming growth factor (TGF)-beta 1/Smads, RhoA/Rho-associated kinase (ROCK), vascular endothelial growth factor (VEGF)/b-fibroblast growth factor (b-FGF) and nuclear factor (NF)-κB. This paper briefly reviews the research progress of these five signaling pathways, and discusses other signaling pathways that may be involved, in order to provide reference and ideas for future experimental research.

Objective: To observe the effect of modified Erchentang on GATA-binding protein-3(GATA3) and T-box expressed in T cells(T-bet) in lung tissue of rats with chronic obstructive pulmonary disease (COPD). Method: Seventy SD rats were randomly divided into seven groups, namely normal group, model group, low, medium and high-dose modified Erchentang group(5,10,20 g ·kg^-1), Xiaokechuan group(5 g ·kg^-1) and Erchentang group(5 g ·kg^-1), with 10 in each group. The rat model of COPD was established by smoking combined with intratracheal dripping of lipopolysaccharide (LPS). After successful modeling, the treatment group was given intragastric administration, and the normal group and the model group were given intragastric administration of equal volume of saline. Enzyme-linked immunosorbent assay (ELISA) was used to determine the concentrations of interleukin-10 (IL-10) and interleukin-12 (IL-12) in rat serum. The expressions of GATA3 and T-bet were detected by real-time fluorescence quantitative polymerase chain reaction (Real-time PCR). The expressions of GATA3 and T-bet in lung tissue were detected by immunohistochemistry (IHC). Result: Compared with the control group, the serum levels of IL-10 in the model group was significantly decreased, while the IL-12 level was significantly increased (P<0.01). The protein and gene expressions of GATA3 in lung tissue were significantly decreased, whereas the expression of T-bet was significantly increased (P<0.01). Compared with the model group, the serum level of IL-10 in each treatment group was increased to varying degrees, while the level of IL-12 was decreased to varying degrees (P<0.05). The mRNA and protein expressions of GATA3 in lung tissue of rats in each treatment group were increased significantly, while T-bet was inhibited (P<0.05). Conclusion: Modified Erchentang may reduce the inflammation of lung tissue and improve lung function in COPD rats by reducing IL-12, increasing the content of IL-10, inhibiting the protein and gene expressions of T-bet, and stimulating the protein and gene expressions of GATA3.

Objective: To explore the effect of modified Erchentang on peroxisome proliferator-activated receptor gamma (PPARγ) protein and gene expressions in lung tissue of chronic obstructive pulmonary disease (COPD) rat model, and the expressions of interleukin-6 (IL-6), interleukin-10 (IL-10) and tumor necrosis factor-alpha (TNF-α) in serum, lung homogenate and bronchoalveolar lavage fluid. Method: Seventy SD rats were randomly divided into seven groups:normal group, model group, high, medium and low-dose modified Erchentang groups (40, 20, 10 g · kg^-1 · d^-1), Xiaokechuan group (5 g · kg^-1 · d^-1), and Erchentang group (5 g · kg^-1 · d^-1). The rat COPD model was established through smoking and intratracheal instillation of lipopolysaccharide (LPS). After successful modeling, the treatment group was given drug by gavage, while the normal group and the model group were given the same amount of saline. The concentrations of IL-6, IL-10 and TNF-α in serum, lung homogenate and bronchoalveolar lavage fluid(BALF) of rats were measured by enzyme-linked immunosorbent assay (ELISA). Real-time fluorescence quantitative PCR (Real-time PCR) was used to detect the expression of peroxisome proliferator-activated receptor gamma (PPARγ), and immunohistochemistry (IHC) and Western blot were used to detect the expression of PPARγ in lung tissue. Result: Compared with the normal group, the levels of IL-6 and TNF-α in serum, lung homogenate and BALF of the model group rats increased significantly (P<0.01), while IL-10 decreased significantly (P<0.01). The expressions of PPARγ mRNA in lung tissue of rats in model group were significantly decreased (P<0.01), and the expression of PPARγ protein was significantly inhibited(P<0.01). Compared with the model group, the levels of IL-6 and TNF-α in serum, lung homogenate and BALF of each treatment group decreased to varying degrees(P<0.01), while IL-10 increased to varying degrees. The excitation of IL-10 and the inhibition of IL-6 and TNF-α in the middle-dose Erchentang group were particularly significant. The PPARγ mRNA and protein expressions in lung tissue of rats in each treatment group were increased to varying degrees (P<0.01). Conclusion: Modified Erchentang may improve pulmonary inflammation and pulmonary function in COPD rats by increasing the expression of PPARγ and the content of IL-10 and decreasing the contents of IL-6 and TNF-α.

Objective: To explore the effect of modified Erchentang on the signal pathway of β₂ adrenergicreceptor(β₂AR)/arrestin beta 2(β-arrestin2) in rats with chronic obstructive pulmonary disease (COPD), and the expression of interleukin-17(IL-17) in serum, lung homogenate and bronchoalveolar lavage fluid. Method: Seventy SD rats were randomly divided into seven groups:normal group, model group, modified Erchentang with high, medium and low doses (40, 20, 10 g · kg^-1 · d^-1), Xiaokechuan group (5 g · kg^-1 · d^-1), modified Erchentang group (5 g · kg^-1 · d^-1), 10 rats in each group. The rat model of COPD was established by smoking and lipopolysaccharide (LPS) intratracheal drip. After successful modeling, the treatment group was given intragastric administration, while the normal group and the model group were given the same amount of saline. Enzyme-linked immunosorbent assay (ELISA) was used to detect the levels of IL-17 in serum, lung homogenate and bronchoalveolar lavage fluid of rats. Real-time fluorescence quantitative PCR (Real-time PCR) was used to detect the expression of β₂AR gene. Western blot was used to detect the expression of β₂AR protein in lung tissue. The expression of β₂AR and β-arrestin2 in lung tissue was detected by immunohistochemistry. Result: Compared with the normal group, the expression of β₂AR protein in lung tissue of model group was significantly decreased(P<0.01). Compared with model group, the expression of β₂AR protein in lung tissue was significantly increased(P<0.01), and the middle dose group of modified Erchentang was different from other groups (P<0.05). Compared with normal group, the expression of β₂AR in model group was significantly lower(P<0.01), compared with model group, the expression of β₂AR in high, medium and low dose group, Xiaokechuan group and modified Erchentang group was significantly higher(P<0.01). The middle dosage group of modified Erchentang was significantly higher than other groups(P<0.01). Compared with normal group, the serum level of IL-17 in the model group was significantly higher(P<0.01). Compared with model group, the serum level of IL-17 in each group was inhibited to a certain extent, especially in the middle dose group of modified Erchentang (P<0.05). Conclusion: Modified Erchentang may increase the expression of β₂AR and β-arrestin2 and decrease the content of IL-17 in order to resist inflammation and improve pulmonary function in COPD rats.
