Objective: To observe the clinical therapeutic efficacy of treatment of prolapse of lumbar intervertebral disc with lumber vertebral traction plus Ding's Rolling Technique.Methods: 133 cases of prolapse of lumbar intervertebral disc were randomly divided into two groups. There were 68 cases in the treatment group, which were treated with lumber vertebral traction plus Tuina. There were 65 cases in the control group, which were treated with simple lumber vertebral traction. Results: There were statistic differences in the two groups (x2=6.86,P＜0.01). The therapeutic efficacy in the treatment group was better than the control group.Conclusion: The clinical therapeutic efficacy treated with lumber vertebral traction plus Ding's Rolling Technique was better than simple lumber vertebral traction in treating prolapse of lumbar intervertebral disc.

Methods Primarily cultured hippocampal neurons prepared by enzymatic digestion of hippocampus isolated from newborn (

Proteins, sugars and esterase isoenzymes of An. anthropophagus and An. sinensis were compared by IEF and two dimensional gel electrophoresis.The results show that there are some differences in the electrophoretic patterns between An. anthropophagus and An. sinensis. The glycoprotein, lipidprotein, glycolipi-dprotein, protein, polysaccharide and esterase isosnzymES showed 10, O, 6, 14, 2 and 13 bands in An. anthropophagus; 10, l, 5, 16, 3 and 15 in An. sinensis. There exist 234 and 240 polypeptide spots in An. anthropophagus and in An. sinensis, respectively, alto-gether 27.8% of polypeptide spots being different.

The current status and important advances in multi-disciplinary treatment for advanced gastric cancer,including surgery,chemotherapy and radiotherapy,were reviewed in this article.An operative scheme based on the stage and biologic behavior of the tumor is adopted with the D_2 procedure combined with intraoperative peritoneal hyperthermic chemotherapy(IPHC) for stage Ⅱ and Ⅲ patients.Accurate preoperative staging is of utmost importance in making an appropriate therapeutic strategy.For patients with stage Ⅲ_B and Ⅳ gastric cancer,neo-adjuvant chemotherapy followed by cyto-reductive surgery,is helpful to prolong survival and improve the quality of life.Besides the 5-FU,cisplatin and doxorubicin based regimen,combination regimens employing newer generation cytotoxic agents including oxaliplatin,irinotecan,taxanes provided more promising efficacy.Postoperative chemo-radiotherapy is presently under investigation.

Long non-coding RNAs (lncRNAs) are deifned as transcripts longer than 200 nt without coding capacities. Although they were initially argued to be transcriptional by-products of RNA polymeraseⅡ, recent evidence suggests that lncRNAs have been associated with a spectrum of biological processes, and aberrant lncRNA expression may be a major contributor to tumorigenesis, progression and prognosis. This study summarizes the up-to-date studies on lncRNAs in urological neoplasms.

Objective To investigate indications of thoracoscopic resection of esophageal carcinomas. Methods A total of 75 patients with esophageal carcinomas underwent video-assisted thoracoscopic surgery (VATS) from July 1997 to July 2003. The dissection of the esophagus and radical resection of lymph nodes were performed using a right-sided VATS approach. Then the stomach was dissociated through an upper-abdominal incision and was pulled up for esophago-gastric anastomosis in the left neck. Results A conversion to open surgery was required in 3 patients, in 2 of whom the tumors had enroded into the hilum and the posterior wall of the heart, and in 1 of whom the azygous vein was ruptured. The operation time was 160~220 min, with the intrathoracic operation time accounting for 60~90 min. The postoperative blood loss was 300~400 ml. No surgery-related deaths were noted. Postoperative complications included 1 case of volvulus of stomach, 2 cases of anastomotic leakage, 1 case of anastomotic stenosis, and 1 case of chylothorax. Follow-up checkups in 60 patients for 3 months ~ 7 years (mean, 4 years) found 2 cases of supraclavicular lymph node metastasis and 1 case of abdominal lymph node metastasis. The 1-, 3- and 5-year survival rates were 85.0% (51/60), 51.7% (31/60) and 40.0% (24/60), respectively. Conclusions Video-assisted thoracoscopic resection of esophageal carcinomas is feasibly suited to patients with localized lesions at phaseⅠ or Ⅱ.

Objective To investigate the effect of melatonin (MT) on the proliferation and apoptosis in human pancreatic cancer cell SW1990 in vitro.Methods SW1990 cell line were treated with MT at different concentrations (0.1,0.5,1.0,2.5 and 5.0 mmol/L) and at different time points (24 h,48 h and 72 h).Cell proliferation was evaluated by MTT and apoptosis was determined by AnnexinV/Pl,cell cycle was determined by flow cytometry,and Western Blot was used to detect the expression of Bcl-2 and Bax.Results MT could inhibit the proliferation of SW1990 cell in a time and dose dependent manner.48 h after 0.1～5.0 mmol/L MT treatment,the proliferation inhibitory rate was 7.4%～85.8%,the proportion of SW1990 cell in phase G0/G1 was 72.6%～85.33%.48 h after 1～5.0 mmol/L MT treatment,the apoptosis rate was 21.5% ～41.7%,and the expression of Bcl-2 was down-regulated and the ratio of Bcl-2/Bax decreased.Conclusions MT could inhibit the proliferation of SW1990 pancreatic cancer cells by up-regulating the expression of Bax and down-regulating the expression of Bcl-2,as well as enhancing apoptosis and blocking SW1990 cell in phase G0/G1.

Five compounds, huyouyisu (1), vomifoliol (2), isoferulic acid (3), 1,2,3-trihydroxy-phenol (4) and p-hydroxy-phenol (5), were isolated from the peels of Citrus changshan-huyou Y.B.Chang for the first time by utilizing repeated column chromatography on silica gel. Among them, huyouyisu (1) is a new compound. The structure was elucidated by using 1D and 2D spectra.

A series of multinuclear diethylenetriamine ligands were synthesized and used as artificial nuclease enzyme model. Target compounds were characterized by 1H NMR, 13C NMR, IR and ESI-MS. Preliminary studies on the cleavage of pUC19 DNA in the presence of metal complexes have also been performed and the results revealed that these complexes could act as powerful catalysts for the cleavage of pUC19 DNA after 48 h under physiological conditions. The hydrolytic cleavage mechanism of DNA plasmid by title compound was confirmed by T4 DNA ligase experiment.
