OBJECTIVETo compare clinical efficacy of Zero-profile implant for anterior cervical discectomy and fusion and conventional titanium plate with cage internal fixation for the treatment of single segmental cervical intervertebral disc herniation.

METHODSFrom August 2011 to March 2014, clinical data of 139 patients with single cervical disc herniation treated with anterior cervical discectomy and interbody fusion with internal fixation were retrospectively analyzed. The patients were divided into two groups according to its operation method. There were 63 patients in group A which performed anterior discectomy and interbody fusion with Zero-profile;76 patients in group B which performed anterior cervical discectomy and cage plate internal fixation. JOA score and Odom functional rating between two groups were compared before and after operation. Videofluorographic swallowing study (VFSS) were used to evaluate thickness of prevertebral soft tissue. Bazaz dysphagia score were used to assess incidence of dysphagia. Postoperative AP X-ray and CT of cervical vertebra at 12 months were applied for evaluating bone graft fusion. Postoperative MRI was applied for evaluating the incidence of adjacent segment degeneration. Blood loss,operative time, preoperative and postoperative JOA score, Odom functional rating and VFSS score, Bazaz score, fusion rate between vertebral bodies and incidence of adjacent segment degeneration were compared between two groups.

RESULTSThere were no statistical meaning between two groups in JOA score, Odom functional rating before and after operation (P > 0.05); and no significant meaning in VFSS score between two groups before operation (P > 0.05); There were no significant difference in operative time and blood loss. There was statistical meaning in VFSS, Bazaz dysphagia score at 2 days, and 6 months after operation (P < 0.05). All patients obtained bone union at 1 year after operation, and no obvious meaning in fusion rate (P > 0.05). Eight patients (12.7%) in group A occurred adjacent segment degeneration and 19 patients (25%) in group B occurred adjacent segment degeneration, and there was significant meaning between two groups (P < 0.05).

CONCLUSIONBoth of Zero-profile implant for anterior cervical discectomy and fusion and conventional cage internal fixation for the treatment of single segmental cervical intervertebral disc herniation could obtain satisfied clinical results. While Zero-profile implant for anterior cervical discectomy and fusion has advantages of lower incidence of adjacent segment degeneration, and its mid and long term following-up results still further observation.

The incidence of male infertility increased year by year, which seriously affects family welfare and social development. This article reviews and sorts out recent years’ studies on acupuncture treatment for male infertility. The results show that acupuncture treatment has produced a good clinical effect on this disease. Some progresses have been made in clinical acupuncture point selection, operating methods, complex treatment and therapeutic mechanism. The clinical effect and the mechanism of action of acupuncture treatment for this disease have been deeply explored from symptom differentiation and classification, acupoint selection and prescription, acupoint stimulation mode, and combined acupuncture and moxibustion therapy so as to provide new ideas for clinical acupuncture treatment and basic study.

Objective To evaluate the number and function of peripheral Vγ2Vδ2+T lymphocytes during Mycobacterium tuberculosis(MTB)infection in human immunodeficiency virus (HIV)infected individuals.Methods Seventy-six HIV/acquired immune deficiency syndrome(AIDS) patients co-infected with MTB were divided into active tuberculosis(TB)group(HIV+TB)and latent TB group(HIV+LTB).T cell subsets of peripheral blood lymphocytes were analysed by flow cytometry.Stimulated by protein purified derivative(PPD)and hydroxymethylbutenyl diphosphate (HMBPP),specific interferon(IFN)-γ producing T cells were detected using enzyme-linked immunospot(ELISPOT)and intracellular cytokine staining(ICS).Data were analyzed by t test.Results The absolute number of CD3'T cells and DroDortion of V72VB2'T cells in CD3+T cells in HIV+TB group were both significantly lower than those in HIV+LTB group(t=-3.67,P<0.01;t=-2.06,P<0.05).PPD-specific IFN-y-producing T cells and percentage of PPD-specific CD4+Tcells in CD3+T cells in HIV+LTB group were both similar with those in HIV+TB group.While HMBPP-specific IFN-γ-producing T cells and percentage of HMBPP-specific Vγ2Vδ2+T cells in CD3+Tcells in HIV+LTB group were both higher than those in HIV+TB group(t=2.71 and t=3.003,respectively;both P<0.0 1).Conclusion The number and function of Vγ2Vδ2+T cells were impaired in HIV/AIDS patients coinfected with active MTB infection,which indicates that Vγ2Vδ2+T cells may be the key immune cells against MTB in individuals with impaired CD4+T cells.

0.05)and the TNM staging (P=0.55).A mild elevated compared other pathological classification was found in small cell lung cancer (0.191?0.275).Conclusions The results showed that RFQ-PCR was suitable for measurement of the mRNA level of PLKI in bronchoscopic bioptic specimens.This study suggest elevated expression of PLK1 might play a important role in development of lung cancer,so that PLK1 might be a potential tumor marker for Lung cancers.Advanced studies will be needed to clarify that PLKI mRNA level do not relate to TNM staging and pathological classification.

Objective: To discuss the effects of acupuncture plus Tuina (Chinese therapeutic massage) in intervening the mental development, motor function, cerebral hemodynamics, and muscle tone in kids with spastic cerebral palsy (CP). Methods: A retrospective analysis was conducted on 87 kids with spastic CP. They were divided into a control group and an observation group based on their original treatment plan. Kids in the control group received symptomatic treatment, motor development therapy, and Tuina treatment. The observation group was additionally given acupuncture treatment. One month was taken as a treatment course. After six courses, the efficacy, change in muscle tone, mental development, gross motor function, fine motor function, and the systolic velocity (Vs), mean velocity (Vm), and pulsatility index (PI) of the anterior cerebral artery (ACA), middle cerebral artery (MCA), and posterior cerebral artery (PCA) were compared between the two groups. Results: After treatment, the muscle tone score dropped in both groups (P<0.05) and was significantly lower in the observation group than in the control group (P<0.05). The observation group achieved more significant efficacy than the control group (P<0.05). After the intervention, the mental development index (MDI), psychomotor development index (PDI), gross motor function measure (GMFM) score, and fine motor function measure (FMFM) score all increased in both groups (P<0.05) and were notably higher in the observation group than in the control group (P<0.05). After treatment, the Vs and Vm of the ACA, MCA, and PCA were markedly higher in the observation group than in the control group (P<0.05), and the observation group was significantly lower than the control group comparing the PI of the ACA, MCA, and PCA (P<0.05). Conclusion: Based on the symptomatic treatment and motor development therapy, Tuina and acupuncture treatment can effectively treat spastic CP children, manifesting as reducing muscle tone, boosting mental development, and improving motor function and cerebral hemodynamics.
