Objective To investigate the clinical efficacy of heat-sensitive point medicinal moxibustion plus percutaneous administration of tetrandrine in treating lumbar intervertebral disc herniation. Methods One hundred and twenty patients with lumbar intervertebral disc herniation were randomized to treatment and control groups, 60 cases each. The treatment group received heat-sensitive point medicinal moxibustion plus percutaneous administration of tetrandrine and the control group, heat-sensitive point medicinal moxibustion alone. The VAS score and the JOA Score for Back Pain score were recorded in the two groups before and after treatment. The clinical therapeutic effects were compared between the two groups. Results There were statistically significant pre-/post-treatment differences in the JOA Score for Back Pain score and the VAS score in the two groups (P<0.01). There were statistically significant post-treatment differences in the JOA Score for Back Pain score and the VAS score between the treatment and control groups (P<0.01). The excellent and good rate was 80.0％ in the treatment group and 55.0％ in the control group; there was a statistically significant difference between the two groups (P<0.01). Conclusion Heat-sensitive point medicinal moxibustion plus percutaneous administration of tetrandrine is an effective way to treat lumbar intervertebral disc herniation.

OBJECTIVETo investigate the mRNA expression of bFGF and MMP-9 in gastric carcinomas and to find their correlation with tumor microvascular density (MVD), invasion, metastasis and patients survival.

METHODSIn situ hybridization and immunohistochemistry technique were used to test the expression of bFGF mRNA and MMP-9 mRNA and protein of CD34 in 105 specimens of gastric carcinoma.

RESULTSIn situ hybridization revealed that the positive rates of bFGF mRNA and MMP-9 mRNA were 60.95 and 58.1%, respectively; The mean MVD (46.09 +/- 11.52, 43.75 +/- 13.41 piece/0.72 mm(2)) in tumors with bFGF mRNA and MMP-9 mRNA positive expression was significantly higher than that (29.41 +/- 12.47; 33.45 +/- 13.92 piece/0.72 mm(2)) in tumors with their negative expression, respectively; The positive expression rates of bFGF and MMP-9 mRNA were correlated to invasion depth (r(s) = 0.211, P = 0.031; r(s) = 0.335, P = 0.001, respectively), growing pattern (r(s) = 0.324, P = 0.001; r(s) = 0.267, P = 0.006, respectively), vessel invasion (r(s) = 0.579, P = 0.001; r(s) = 0.209, P = 0.032, respectively), lymph node metastasis (r(s) = 0.405, P = 0.001; r(s) = 0.343, P = 0.001, respectively) and distant metastasis (r(s) = 0.474, P = 0.001; r(s) = 0.468, P = 0.001, respectively), but not correlated to tumor type (r(s) = 0.134, P = 0.173; r(s) = 0.103, P = 0.145, respectively) and differentiation (r(s) = 0.096, P = 0.332; r(s) = 0.102, P = 0.298, respectively); And then, the mean MVD in tumors with infiltrating type, stage T(3)-T(4), vessel invasion, lymph node metastasis and distant metastasis was significantly higher than that in tumors with expanding type (t = 10.105, P = 0.001), stage T(1)-T(2) (t = 5.961, P = 0.001), non-vessel invasion (t = 7.394, P = 0.001), non-lymph node metastasis (t = 3.819, P = 0.01) and non-distant metastasis (r = 10.578, P = 0.001); There was a positive relationship between MVD and bFGF mRNA and MMP-9 mRNA (t = 3.207, P = 0.002; t = 7.035, P = 0.001), respectively; the mean survival time in cases with positive bFGF mRNA and MMP-9 mRNA and MVD value >/= 39.5 was significantly shorter than that in cases with their negative expression and MVD value < 39.5.

CONCLUSIONSbFGF and MMP-9 promote angiogenesis in gastric cancer. Test of the expression of bFGF and MMP-9 may act as an useful index to determine angiogenesis, invasion, metastasis and patients survival.

BACKGROUNDThe aim of this study was to investigate DNA content and expression of c-erbB-2, PS2, and prostate-specific antigen (PSA) proteins in breast carcinomas with neuroendocrine (NE) cell differentiation.

METHODSChromogranin, c-erbB-2, PS2, and PSA in 131 samples of breast cancer were detected immunohistochemically. Classic Feulgen staining image analysis techniques were used to quantify DNA content in 81 of the breast cancer samples.

RESULTSThe c-erbB-2 positive rate in breast carcinoma samples containing neuroendocrine cells was 37.5% and the rate of high expression of c-erbB-2 (++ or +++) was 33.3%, both significantly lower than that in breast carcinomas without neuroendocrine cells (62.6% and 68.7%, respectively, P < 0.05). The rates of positive PS2 and PSA expression in breast carcinoma samples containing neuroendocrine cells were 72.2% and 55.0%, respectively, both significantly higher than that in breast carcinoma samples without neuroendocrine cells (45.0% and 16.4%, respectively, P < 0.05). In NE(+) samples, the integral optical density, DNA index, DNA stemline peak, > 5 c aneuploidy cells, and rate of aneuploidy among cells were all lower than that in NE(-) breast carcinomas (P < 0.01). In NE(+) grade I or II breast carcinomas, these indices were also all lower than that in the NE(-) breast carcinoma samples (P < 0.01).

CONCLUSIONBreast carcinomas with neuroendocrine differentiation have a lower rate of malignancy. Neuroendocrine differentiation could serve as a prognostic marker in clinical practice.

OBJECTIVETo study the possible clonal origin of neuroendocrine cells in colorectal adenocarcinoma.

METHODSTwenty-six microsatellite loci were screened using laser capture microdissection, DNA extraction and whole genome amplification. Microsatellite instability (MSI) and loss of heterozygosity (LOH) in adenocarcinoma cells and neuroendocrine cells amongst 30 cases of colorectal carcinoma with neuroendocrine differentiation were detected using polymerase chain reaction-single strand conformation polymorphism (PCR-SSCP)-silver staining. The mutation status of p53 was evaluated by PCR-sequencing. The clonal origin of neuroendocrine cells in colorectal adenocarcinoma was determined.

RESULTSAmongst the 30 cases studied, the prevalence of MSI was 16.9% while that of LOH was 8.5%. The rate showed no statistically significant difference between adenocarcinoma cells and neuroendocrine cells. In 6 cases, the microsatellite alteration was entirely consistent. In 23 cases, the rate of microsatellite alteration consistency was greater than that of inconsistency. In 1 case, the consistency and inconsistency rates were identical. There was statistically significant difference between consistency and inconsistency of microsatellite alteration. The prevalence of p53 mutation was 16.7% which was the same for both adenocarcinoma cells and neuroendocrine cells.

CONCLUSIONSAdenocarcinoma cells and neuroendocrine cells in colorectal adenocarcinoma with neuroendocrine differentiation have similar biologic changes. It is likely that they are of identical origin.

OBJECTIVETo investigate the therapeutic efficacy and safety of aspartate-ornithine granules in patients with nonalcoholic steatohepatitis (NASH).

METHODSSeventy-two patients with NASH were included in this multiple-dose parallel controlled clinical trial and received a 12-week course of aspartate-ornithine granule treatment at either high-dose (6 g bid po; n = 38) or low-dose (3 g bid po; n = 34). Clinical efficacy was assessed by monitoring data from urinalysis, serologic tests (alanine aminotransferase (ALT), aspartate aminotransferase (AST), gamma-glutamyl transferase (GGT), and triglyceride (TG)), and abdominal computed tomography (CT) scan. Safety was assessed by occurrence of adverse events (fatigue, anorexia, abdominal distension, nausea, and vomiting). Statistical analyses were conducted to determine the significance of differences between parameters before (baseline) and after treatment.

RESULTSAfter 12 weeks of treatment, the liver and spleen CT ratios in both the high-dose group (0.89 +/- 0.19) and the low-dose group (0.80 +/- 0.15) were significantly higher than at baseline (S = 329, P less than 0.0001 and S = 246, P less than 0.0001); the overall improvement was more robust in the high-dose group (52.63%) than in the low-dose group (38.23%) (Z = -2.1042, P less than 0.05). After 6 and 12 weeks of treatment, the serum ALT levels in both the high-dose group and the low-dose group were significantly lower than at baseline (6 weeks: S = 324.5, P less than 0.0001 and S = 223, P less than 0.0001; 12 weeks: S = 370.5, P less than 0.0001 and S = 297.5, P less than 0.0001); the overall improvement was more robust in the high-dose group (79.0%) than in the low-dose group (53.0%) (Z = -2.0533, P less than 0.05). Similar trends were seen for the serum levels of AST and GGT after 6 and 12 weeks of treatment (all P less than 0.01) and serum levels of TG after 12 weeks of treatment. The rate of adverse reactions was low and similar between the two groups (high-dose: 4.8% and low-dose: 4.4%; all gastrointestinal).

CONCLUSIONAspartate-ornithine granule therapy was an effective and safe treatment of nonalcoholic steatohepatitis, with the higher dose of 6 g bid po providing more robust clinical benefit without affecting the safety profile.
