BACKGROUND:Lumbar disc herniation is a clinical syndrome of lumbar pain and radiated pain of the lower limb induced by biochemical changes after intervertebral disc degeneration. Transforaminal endoscopic spine system (TESSYS) and Yeung endoscopic spine system (YESS) are commonly used in the clinic, but their effects are different.
OBJECTIVE:To compare the curative effect of TESSYS and YESS in treatment of lumbar disc herniation. METHODS:Fol ow-up data of 134 cases of lumbar disc herniation were retrospectively analyzed. They were assigned to TESSYS group (n=76) and YESS group (n=58). Intraoperative condition, pain at various time points after repair, and lumbar function changes were compared between the two groups.
RESULTS AND CONCLUSION:(1) No significant difference in Visual Analogue Scale and Oswestry Disability Index scores was detected between the two groups before repair (P>0.05). At 1, 3, and 6 months after repair and during final fol ow-up, above scores were significantly decreased in both groups (P<0.05). Above scores were significantly lower in the TESSYS group than in the YESS group at various time points after repair (P<0.05). (2) No significant difference in Japanese Orthopedic Association score was found between the two groups before repair (P>0.05). Japanese Orthopedic Association score was greater in the TESSYS group than in the YESS group at 1, 3 and 6 months fol owing repair and during final fol ow-up (P<0.05). (3) The excel ent and good rate was significantly greater in the TESSYS group than in the YESS group during final fol ow-up (P<0.05). (4) Operation time and incision length were significantly shorter in the TESSYS group than in the YESS group. No significant difference in the amount of bleeding was detectable between the two groups (P>0.05). Results suggest that TESSYS for lumbar disc herniation was characterized by smal trauma, mild pain and good recovery of function.

Objective To observe the vascular imaging the pathological changes in the patients with breast cancer after neoadjuvant intraarterial chemotherapy. Methods Before intraarterial infusion, DSA were performed on 96 patients with breast cancer. Pathological changes were studied after operation. Results The blood supply of breast cancer mainly arises from the lateral thoracic and subscapular arteries. Abnormalities in the vascular architecture of breast cancer include irregular bolus arrangement, contrast staining, pooling of contrast material. Degeneracy and necrosis can be seen in the tumor cells after intraarterial chemotherapy. The stromal edema, infiltration of inflammatory cells and fibroplasia may take place. Conclusions Intraarterial infusion of neoadjuvant chemotherapy is effective in the patients with breast cancer.

Objective To investigate the functions of blood plasma homocysteine (Hcy) and high sensitivity C-response protein (hs-CRP) in the chronic obstructive pulmonary disease (COPD) in pathogenesis plays,and observe whether there was associations with disease severity and the correlations.Methods Forty-one patients with COPD were collected from August 2010 to February 2011,and 35 healthy persons as control group.Blood plasma Hcy,hs-CRP,forced expiratory volume in one second account predicted (FEV1％ predicted),and arterial pressure of oxygen (PaO2,arterial blood gases analysis) were measured in COPD patients and controls.Results Plasma Hcy concentration was (22.07 ± 12.13) μmol/L in COPD patients,but (9.89 ±4.41) μmol/L in controls,there were significant differences between two subjects (t =1.674,P ＜0.01).COPD patients had a higher serum hs-CRP concentration (8.60±3.85) mg/L than control's (4.24 ±0.57) mg/L (t =1.682,P ＜ 0.01).Along the descent of FEV1％ predicted,plasma Hcy and hs-CRP were elevated gradually,both sides show a negative correlation (r =-0.45,-0.49,P ＜ 0.05).And plasma Hcy and hs-CRP present a positive correlation in COPD patients (r =0.68,P ＜ 0.01).Conclusion Plasma Hcy was significantly elevated in COPD patients,positive correlation related to COPD severity and positive correlation related to serum hs-CRP.

The incidence and mortality of colorectal cancer (CRC) increased rapidly in recent decades and become enormous challenges in China.Lack of effective early warning of molecular markers and dynamic monitoring technology in term of early diagnosis,treatment evaluation,dynamic recurrence and metastasis monitoring are the clinical diagnosis and treatment bottlenecks of CRC.Traditional diagnosis and treatment of CRC rely on a single level of patient information with low accuracy.Based on the system of biology medical model,to carry out a joint diagnostic model,will overcome the traditional problems through a number of multi-level information integration of the joint diagnosis model,will significantly improve the sensitivity and specificity of diagnosis of CRC.The major challenge in patients with advanced and metastatic CRC is the instability of the tumor genome and the treatment-induced resistance during chemotherapy and targeted therapy.It is necessary to carry out continuous dynamic biopsy in order to accurately guide the development of treatment decisions.Compared with the pathological examination of traditional surgical specimen,liquid biopsy,such as circulating tumor cells,circulating tumor DNA detection technology,with noninvasive,real-time dynamic monitoring,could evaluate the efficacy of treatment,and guide the precise individual diagnosis and treatment.Today,the new strategy and new technology need to undergo clinical trials urgency,through technology optimization,reduction of costs and improvement of detection accuracy,would quickly extended to clinical applications in future.

OBJECTIVE To investigate the effect of furanodiene(FDE),a diterpene derived from the medicinal plant Zedoary,on apoptosis of human gastric cancer MGC-803 cells induced in vitro. METHODS MGC-803 cells were treated with FDE 46.29~740.74μmol·L-1 for 24,48 and 72 h,and the cell viability was detected with MTT assay. Cell morphology was observed by light microscopy and Hoechst33342 staining. Flow cytometry was used to detect cell apoptotic rate and cell cycle. Rh123 staining and fluorescence probe DCFH-DA were employed to detect the changes in mitochondrial membrane potential (MMP) and reactive oxygen species(ROS). RESULTS MTT Results showed that FDE 46.29-740.74μmol · L-1 exhibited significantly higher cytotoxicity to gastric cancer MGC-803 cells. IC50 for MGC-803 of 24,48 and 72 h treatment was 347.91,257.41 and 101.01μmol·L-1,respectively. Treatment with FDE 92.58-370.32μmol·L-1 for 24 h also caused significant morphological changes in MGC-803 cells. AnnexinⅤ-FITC/PI double staining showed that the apoptotic rate increased after FDE 92.58-370.32μmol·L-1 treatment for 24 h(P<0.05). FDE enabled MGC-803 cell cycle arrest in S phase. DCFH-DA staining showed that FDE resulted in an increase in intracellular ROS levels(P<0.05) when PDE concentration was 370.37μmol·L-1(P<0.05). MMP decreased after FDE treatment when PDE concen?tration was 370.37μmol·L-1(P<0.05). CONCLUSION FDE Possesses potent tumor selected toxicity and can induce apoptosis of MGC-803 cells through cell cycle arresting,which is related to inhibition of DNA biosynthesis.

In this study, the effect of prophylactic anti-inflammation on the development of smoke-induced emphysema was investigated. Young male guinea-pigs aged 1.5-2 months (weighing 198.3+/-26.9 g) were randomly divided into 4 groups: group A (cigarette smoke exposure only), group B (cigarette smoke exposure plus pentoxifylline-rich (PTX, 10 mg/d) forage feeding), group C (cigarette smoke exposure plus intermittent cortical steroid injection (Triamcinolone acetonide, 3 mg, i.m., every three weeks) and control group (group D: animals with sham smoke exposure, raised under the same conditions). Animals in group A, B and C were exposed to smoke of cigarettes for 1 to 1.5 h twice a day, 5 days a week. All animals were killed at the 16th week and followed by morphometrical analysis of the midsagittal sectioned lung slices. Smoke exposure of 16 weeks resulted in visible emphysematous development in Group A but not in Group B and C. It was evidenced by the indicator of air-space size, mean linear intercept (Lm): 120.6+/-16.0 microm in Group A; 89.8+/-9.2 microm in Group B and 102.4+/-17.7 microm in Group C. The average Lm in either group B or group C was shorter than that in Group A (ANOVA and Newman-Keuls test, F=8.80, P=0.0002) but comparable to that (94.8+/-13.2 microm) in group D (P>0.05). It is concluded that long-term prophylactic anti-inflammation inhibits pulmonary emphysema induced by cigarette smoking in the guinea pigs.
