OBJECTIVETo observe the effect of acupuncture along affected meridian on the mem- brane metallo-endopeptidase (MME) gene expression of migraine patients without aura (MO) of Gan-yang hyperactivity syndrome (GYHS).

METHODSTotally 20 MO patients of GYHS were randomly assigned to the acupoint group (acupuncture along affected meridian) and the non-acupoint group, 10 cases in each group. Needling was performed once per day for 10 consecutive days. Gene chip technology was used to obtain two sets of gene expression profiles and analyzed using Gene Ontology (GO).

RESULTSIn the acupoint group, MME gene expression decreased after needling (P = 0.0023).That gene was rich in the beta-amyloid metabolic process (P = 3.16E-05) and the peptide metabolic process (P = 0.009612). Its expression was not seen in the non-acupoint group.

CONCLUSIONThe effect of point selection along affected meridian could be achieved possibly by regulating the MME gene expression.

OBJECTIVETo study the impact of organized stroke ward on the therapeutic effect in stroke patients.

METHODSA total of 2637 patients with acute stroke were randomly assigned to organized stroke ward or the general ward for treatment, and the rates of mortality, nonrecovery, improvement, and recovery were compared between the two groups.

RESULTSThe rates of mortality, nonrecovery, improvement, and recovery in 5 years were 2.00%, 0.90%, 74.94% and 22.16% respectively in the organized stroke ward group, as compared to 3.26%, 1.02%, 74.01% and 21.71% in the general ward group, respectively. The mortality rate was significantly lower in organized stroke ward (P<0.05), but no significant difference was found in the rates of nonrecovery, improvement, or recovery between the two groups (P>0.05).

CONCLUSIONAdmission of the stroke patients in organized stroke ward for treatment can be associated with lowered mortality rate.

Objective:To investigate the effect of botulinum neurotoxin type A (BoNT/A) on Nav1.3 sodium channels and the function of sodium current in neuropathic pain.Methods:Eighteen adult rats had a spared nerve injury (SNI) induced and then were randomly divided into a saline group and a BoNT/A group, each of 9. Another 9 rats formed a fake operation group, Five days after the SNI, BoNT/A (7U/kg or 15U/kg) or saline was subcutaneously administered into the plantar surface of a hindpaw. On the 3rd, 7th and 14th day after the injection, the SNI rats′ paw withdrawal threshold was measured. On the 7th and 14th day the expression of Nav1.3 protein in dorsal root ganglion (DRG) neurons was examined using western blotting, while any change in the functional tetrodotoxin-sensitive (TTX-S) current was recorded using the patch clamp technique.Results:Administration of BoNT/A at either 7U/kg or 15U/kg significantly increased the SNI-induced mechanical allodynia. The expression of Nav1.3 protein in DRG neurons increased significantly after the SNI, but had decreased significantly by the 7th and 14th day after the administration of BoNT/A. BoNT/A significantly decreased the current density in TTX-S sodium channels in DRG neurons following SNI.Conclusion:Administration of BoTN/A affects the expression of Nav1.3 protein and functional TTX-S current, relieving neuropathic pain.

ObJective To summarize the microsurgieal techniques through direct Sylvian fissure approach. Methods A retrospective analysis was conducted in 62 patients undergoing microsurgeries through direct Sylvian fissure approach, including 4 with cavernous angioma in the Sylvian fissure, 5 with insular lobe tumors, 33 with middle cerebral artery aneurysms, 15 with glioma spanning or invading the Sylvian fissure, 1 with metastatic tumor, 2 with arteriovenous malformations, and 2 with temporal lobe epilepsy. Results All the vascular lesions were exposed satisfactorily and managed appropriately. Of the 19 cases ofgliomas and metastatic tumors, total resection was achieved in 13 cases, and subtotal resection in 6 cases. Transient aphasia or hemiparesis occurred postoperatively in a few patients but all recovered within 1 or two months. Conclusions The Sylvian fissure provides a good surgical route as a subarachnoid space between the frontal, parietal, temporal and insular lobes. The Sylvian fissure should be carefully separated under the operating microscope with high-power magnification, and tension-free retaction is critical in important language areas. In the management of tumors involving the Sylvian fissure, we recommend that extended resection be performed after exposure and appropriate preservation of important blood vessels in the fissure.

OBJECTIVETo provide right time points in selection of right aged animals and the normal physiological data of TX mice.

METHODS7-12 months old TX and DL mice were studied, each group contained 3 female and 3 male mice of TX or DL mice. The concentration of copper in the serum, dry tissues (liver, brain and kidney), together with copper biochemistry indexes were measured. The liver histopathology was observed under light microscopy and electron microscope.

RESULTSTransaminase increased significantly only in 10 and 11-month- old (AST(TX10) = 218.3 U/L, AST(TX11) = 197.5 U/L, AST(DL10) = 171.5 U/L, AST(DL11) = 165.0 U/L, P(10) less than 0.001, P(11) = 0.022), but the copper concentration of liver, brain and kidney was significantly increased during 7-12 month old (the average concentration of copper, Liver(TX) = (750.0 +/- 85.5) mg/kg, Brain(TX) = (39.7 +/- 2.2)mg/kg, Kidney(TX) = (29.8 +/- 5.0) mg/kg, Liver(DL) = (11.6 +/- 1.5) mg/kg, Brain(DL) = (16.8 +/- 0.9) mg/kg, Kidney(DL) = (14.2 +/- 1.0) mg/kg, t = 21.16, 23.60, 7.47, for all these organs P less than 0.05).

CONCLUSIONTX mice is a suitable model of liver disease with natural recovery, so selecting animal model of suitable time point is very important.

OBJECTIVETo evaluate relative factors affecting the efficiency of ultrasound-guided compression repair in iatrogenic femoral artery pseudoaneurysm.

METHODSUltrasound-guided manual compression was performed in 42 patients of iatrogenic femoral artery pseudoaneurysm from June 2004 to June 2010. There were 28 male and 14 female patients, with a mean age of (52 ± 5) years. These patients were presented with femoral artery pseudoaneurysm after catheterisation procedure by percutaneous femoral artery puncture and confirmed by color doppler flow image. Ultrasound-guided manual persistent compression with probe was performed at the puncture site between femoral artery and pseudoaneurysm, until completely thrombosis of pseudoaneurysm, whereas the pseudoaneurysm failed to complete closure required surgical repair.

RESULTSOut of 42 patients, 34 patients (81.0%) were successfully treated by compression resulted in completely thrombosis. There were 8 (19.0%) failures conversion to surgery. Factors associated with success were size of pseudoaneurysm (< 25 mm, 25 - 40 mm, > 40 mm; χ(2) = 13.956, P = 0.001), anti-coagulation status (χ(2) = 5.578, P = 0.010), depth of artery break (< 50 mm, 50 - 80 mm, > 80 mm; χ(2) = 14.055, P = 0.001), pseudoaneurysm communicated with common femoral artery, superficial femoral artery and profunda femoral artery (χ(2) = 8.968, P = 0.011), as well as days to presented with pseudoaneurysm (< 3 d, ≥ 3 d; χ(2) = 5.733, P = 0.012). In multivariate Logistic regression analysis, success by compression was associated with size of pseudoaneurysm (WALD = 5.34, P = 0.021) and with depth of artery break (WALD = 4.84, P = 0.028).

CONCLUSIONThe ultrasound-guided compression repair of iatrogenic femoral artery pseudoaneurysm is safe, convenient, inexpensive and reliable treatment.

OBJECTIVETo study the biological properties of human dental pulp cells (HDPC) by cloning and analysis of genes differentially expressed in HDPC in comparison with human gingival fibroblasts (HGF).

METHODSHDPC and HGF were cultured and identified by immunocytochemistry. HPDC and HGF subtractive cDNA library was established by PCR-based modified subtractive hybridization, genes differentially expressed by HPDC were cloned, sequenced and compared to find homogeneous sequence in GenBank by BLAST.

RESULTSCloning and sequencing analysis indicate 12 genes differentially expressed were obtained, in which two were unknown genes. Among the 10 known genes, 4 were related to signal transduction, 2 were related to trans-membrane transportation (both cell membrane and nuclear membrane), and 2 were related to RNA splicing mechanisms.

CONCLUSIONThe biological properties of HPDC are determined by the differential expression of some genes and the growth and differentiation of HPDC are associated to the dynamic protein synthesis and secretion activities of the cell.

OBJECTIVETo investigate the expression of syndecan-1 protein at different stages in the course of gastric carcinoma and its significance in carcinogenesis and metastasis.

METHODSThere were 56 cases of chronic gastritis, 50 cases of chronic atrophic gastritis, 59 cases of intestinal metaplasia, 61 cases of displasia, and 112 cases of gastric carcinoma. Among the carcinoma cases, 55 were without and 57 with lymph node metastases. All paraffin-embedded tissue samples were assessed by immunohistochemistry.

RESULTSThe syndecan-1 positive rate was 96.43% (54/56) in gastritis, 98.00% (49/50) in chronic atrophic gastritis, 100.00% (59/59) in intestinal metaplasia, 91.80% (56/61) in displasia, 45.45% (25/55) in gastric carcinoma without, and 24.56% (14/57) in gastric carcinoma with lymph node metastases. There was no significant difference among chronic gastritis, chronic atrophic gastritis and intestinal metaplasia (P > 0.05). There was a significant difference between displasia group and gastric carcinoma group (P <0.05), as well as between gastric carcinoma with and without lymph node metastases. There was a significant difference among well, moderately and poorly differentiated carcinoma groups.

CONCLUSIONA decreasing expression of syedecan-1 in the development of gastric carcinoma is related with gastric carcinogenesis, and it may further promote metastasis of gastric carcinoma.

BACKGROUNDIt is not clear if there is a difference in prognosis between male breast cancer (MBC) and female breast cancer (FBC) patients. The aim of this study was to compare the prognosis of MBC and FBC patients in China and the prognosis of MBC and their corresponding postmenopausal FBC patients.

METHODSThirty-five MBC patients who were treated at the Sun Yat-sen University Cancer Center between 1969 and 2004 were enrolled in the study. Seventy FBC patients who were matched with the MBC patients for TNM stage, year of diagnosis, and age at diagnosis were simultaneously enrolled in the study. A second group comprising 18 MBC patients and their corresponding 36 matched postmenopausal FBC patients were also enrolled. The whole group and the postmenopausal groups were compared for five- and ten-year survivals.

RESULTSAll the factors that could potentially affect prognosis were comparable among the groups except more FBC than MBC patients underwent endocrine therapy and a modified radical mastectomy. The 5- and 10-year survivals in the whole group were 81.6% and 60.3% for men and 90.7% and 73.5% for women (P = 0.02). The 5- and 10-year survival in the postmenopausal group was 82.5% and 100% for men and 66.0% and 85.9% for women (P = 0.159).

CONCLUSIONSChinese FBC patients had a better prognosis than Chinese MBC patients. However, MBC patients and their corresponding postmenopausal FBC patients had a similar prognosis.
