As a common disease in clinical, the treatment of lumbar disc herniation (LDH) focused on local intervertebral disc, such as surgery and other interventional therapy treatment, but postoperative complications and recurrence rate has been a difficult problem in the field of profession. With the development of spine biomechanics and anatomy, researches on lumbar herniation also increased. Researchers discovered that the incidence and prognosis of LDH were inseparable with local muscle and soft tissue. As the deep paraspinal muscles, multifidus muscle plays an important role to make lumbar stability. Its abnormal function could reduce the stable of lumbar spine, and the chronic lumbar disease could also lead to multifidus muscle atrophy.

OBJECTIVETo study the effect of Shugan Jiangu Recipe (SJR) on bone mineral density (BMD) and serum bone metabolic biochemical markers in postmenopausal breast cancer patients with osteopenia.

METHODSTotally 38 patients of postmenopausal women with breast cancer, who received aromatase inhibitors (AIs), were assigned to the treatment group (21 cases) and the control group (17 cases) by using random digit table. All patients took Caltrate D Tablet (containing Ca 600 mg and Vit D3 125 IU), one tablet daily. Patients in the treatment group took SJR, 6 g each time, twice daily for 6 successive months. The bone mineral density (BMD) level was detected before treatment and at months 6 after treatment. Levels of bone alkaline phosphatase (BALP), bone gla protein (BGP), tartrate-resistant acid phosphatase (TRAP), and C-terminal telopeptide of type II collagen (CTX-II) were detected by enzyme linked immunosorbent assay (ELISA). The drug safety was also assessed.

RESULTSCompared with before treatment, BMD of L2-4 and femur neck obviously increased in the treatment group at month 6 after treatment (P < 0.01), serum BALP and TRAP decreased (P < 0.05). Compared with before treatment, BMD of L2-4 and femur neck obviously decreased in the control group at month 6 after treatment (P < 0.05), serum BALP and TRAP increased (P < 0.01). Compared with the control group, lumbar and femur neck BMD obviously increased, serum levels of BGP and BALP obviously decreased, and serum levels of CTX-II and TRAP obviously increased in the treatment group at month 6 after treatment (P < 0.01). No serious adverse event occurred during the treatment period. Bone fracture occurred in one case of the control group (5.8%).

CONCLUSIONSJR could attenuate bone loss of postmenopausal women with breast cancer who received AIs, increase BMD and improve abnormal bone metabolism.

OBJECTIVE Bergapten (BG), is a furanocoumarin derived from herbal and citrus extracts can act as antioxidant and selective anticancer agents.The current study aimed to investigate whether bergapten would attenuate immunosenescence and to exploreits immunomodulatory effects on immune responses in D-galactose-induced aging BALB/c mice.METHODS Firstly,mice were given D-galactose(180 mg·kg-1)subcutaneous injections for 30 d.To evaluate the establishment of the aging-related effect in mice, serum samples of BALB/c mice were collected from tail vein. Aging BALB/c mice were freely divided into three groups: negative control group received 1% Tween 80 solution only, named D-gal group. Positive groups were received BG administration at the dose of 20 and 100 mg·kg-1, named D-gal+BG(20)group and D-gal+BG(100)group,respectively.Effects of bergapten on T lympho-cyte proliferation and flow cytometry were assessed by using the splenic cell suspension. Enzyme linked immunospot kits were used to quantitatively determine interferon-γ(IFN-γ)and interleukin-4(IL-4) levels of the isolated serum. Immunophenotype was determined by using mixture of antibodies includ-ing anti-CD3,anti-CD4,and anti-CD8.RESULTS Bergapten(20 mg·kg-1)therapy can modulate immu-nity against viral epidemics and attenuate aging-induced immune deficiency(P<0.01),which was correlat-ed with the decline in the activation of the Th and Tc responses in D-galactose induced aging BALB/c mice.According to the in vivo results,bergapten exposure up-regulated the secretion of IFN-γ and IL-4 in T-helper 1(Th1)and T helper 2(Th2)cells(P<0.05,P<0.01).Additionally,BG(20 mg·kg-1)restored antigen-specific CD4+and CD8+T cells in aging models (P<0.05, P<0.01), which may help to curing chronic infections. CONCLUSION The beneficial effect of bergapten in D-galactose induced aging BALB/c mice may be due to the Th and Tc responses activation.

Compared to pre-treatment level, the brain functional activity in effective patients was mainly inhibited , the inhibited areas were located in the right side of prefrontal cortex and cerebellum;while the brain functional activity was generally enhanced in ineffective patients.Conclusion:SM can affect the brain functional activity of patients with LDH , the inhibited areas is mainly located in prefrontal cortex and cerebellum when SM treatment is effective .

OBJECTIVETo investigate the effect of Shen-Fu (SF) injection on gastrointestinal tract injury and its potential mechanism.

METHODSThirty-eight patients undergoing elective open heart surgery were assigned to Group C (control group, n=18) and Group SF (n=20) randomly. In Group SF, the patients received intravenous injection of SF (0.5 ml/kg) at the beginning of the surgery followed by a continuous infusion of 100 ml SF (1.0 ml/kg) solution diluted by saline at a rate of 0.004 ml x Kg(-1) x min(-1) with a Grasby pump. The control group was injected with normal saline in the same volume. Gastric intramucosal pH (pHi), activity of blood diamine oxidase (DAO), and concentrations of blood LPS and IL-6 were measured before CPB (S0) and 1 h (S1) and 2 h (S2) after aortic declamping, respectively.

RESULTSIn Group C, pHi value was significantly lower at S1 and S2 than at S0 (mean P<0.01) and blood DAO and concentrations of LPS and IL-6 were significantly higher at S1 and S2 than at S0 (mean P<0.01). In Group SF, pHi was obviously lower at S1 and S2 than at S0 (P<0.05) but LPS and IL-6 levels and DAO were higher at S0 (mean P<0.05). Blood DAO and LPS level demonstrated significant negative correlations with pHi (mean P<0.01) while LPS concentration showed a positive correlation with blood DAO (P<0.01) and IL-6 concentration (P<0.05). At S1 and S2 after aortic declamping, the levels of pHi were higher in Group SF than in Group C (mean P<0.01 ) but DAO and LPS and IL-6 levels were significantly lower in Group SF than in Group C (P<0.01).

OBJECTIVETo study effects of strengthening exercise with strong tendon on the lumbosacral multifidus muscle.

METHODSAmong 30 healthy volunteers, there were 21 males and 9 females, with an average age of(31.30±6.48) years old(ranged, 25 to 55 years old). The mean BMI was (21.70±1.95) kg/m²(ranged, 18.1 to 24.9 kg/m²). The ultrasonic image was used to analyze the thickness of lumbosacral multifidus(LM) under the follow conditions: supine position, and supine position with leg lifting 30°, 60°, 90°; seat and hip flexion, flexion to limit position, front to limit position with both hands climbing and strengthening the kidneys and the waist.

RESULTSThe average lumbosacral multifidus thickness was (16.867±2.460) mm, (19.010±2.510) mm, (22.477±2.220) mm, and(27.593±2.370) mm respectively in supine position with leg lifting 0°, 30°, 60°, 90°. There were statistical differences(=423.619,<0.05). The average lumbosacral multifidus thickness was (25.810±2.440) mm, (15.677±2.130) mm, and (15.533±2.110) mm respectively in seat and hip flexion, flexion to limit, front to limit positions with both hands climbing and strengthening the kidneys and the waist. There were statistical differences(=597.789,<0.05).

CONCLUSIONSWhen healthy volunteers in Shi's Orthopedics strengthen muscle exercises training, multifidus thickness is increased with the increasing of leg degree, reduced with the increasing of the flexion degree. It can change the stretching state of multifidus muscle by a specific training, so as to achieve the purpose of training the multifidus muscle.

OBJECTIVETo identify plasma biomarkers with specific relation to the various liver fibrosis stages that can be used to assess hepatitis B virus (HBV)-infected patients for non-invasive liver fibrosis and to evaluate the prognosis of the liver fibrosis.

METHODSPlasma samples were collected from 80 HBV-positive patients at the Hepatitis Department of Shanghai Public Health Clinical Center between September 2008 and January 2011. The samples were grouped according to the patient's stage of hepatic fibrosis determined by liver biopsy: S0-1 (n = 40), S2-3 (n = 20), and S4 (n = 20). Each plasma sample was processed to remove the two most abundant proteins, albumin and immunoglobulin G (IgG), and then resolved by two-dimensional (2D) electrophoresis. ImageMaster 2D analysis software was used to identify differentially expressed proteins related to the liver fibrosis stages. After trypsin digestion, the differential proteins were identified by online reversed-phase nano-flow liquid chromatography coupled with electrospray ionization ion trap mass spectrometry (MS).

RESULTSThe patients in the three groups were not significantly different in age (range: 30-50 years; P = 0.053) or sex (x² = 0.155, P = 0.926). Low-abundance proteins were efficiently enriched by the albumin/IgG depletion method. Fourteen differentially expressed proteins were detected among the S0-1, S2-3 and S4 groups, all of which were identified by tandem MS and included fibrinogen gamma chain, haptoglobin, complement C3, Ig kappa chain C region, and apolipoprotein A-I.

CONCLUSIONPlasma proteomic analysis of chronic hepatitis B patients identified a panel of differentially expressed proteins related to different stages of liver fibrosis. These proteins may represent diagnostic and prognostic biomarkers of HBV-related hepatic fibrosis.
