Objective To investigate the expression of aquaporin 2 (AQP2) in an endolymphatic hydrops ani-mal model .Methods Forty adult guinea pigs were randomly divided into experiment group and control group (20 animals in each group ) . Guinea pigs in the experiment group were treated with deamino arginine vasopressin (DDAVP) intraperitoneally at the dosage of 4 μg · kg -1 · d-1 for 7 days ,while those in the control group were treated with physiological saline .The endolymphatic hydrops and expression of AQP2 in cochleas of all animals were evaluated by Hematoxylin and Eosin stain ,immunohistochemistry and Western blot .Results The endolymphatic hydrops in the experiment group were more severe than that in the control group(P<0 .05) .Expression of AQP2 were found in the stria vascularis and spiral ganglions in both groups with similar patterns .Both immunohistochem-istry and Western blot showed that the expressions of AQP2 in the experiment group were significantly stronger(P<0 .05 ) .Conclusion DDAVP can up-regulate the expression of AQP2 in the cochleae of guinea pigs ,thus may be closely related to the pathogenesis of endolymphatic hydrops .

OBJECTIVETo compare the difference in the efficacy on cervical type of cervical spondylosis (CS) between the combined treatment of sword-like needle and chiropractic spinal manipulation (the combined therapy) and the simple chiropractic spinal manipulation.

METHODSOne hundred and thirty-eight cases of cervical type of CS were randomized into a combined therapy group (76 cases) and a simple chiropractic spinal manipulation group (62 cases). In the combined therapy group, the sword-like needle therapy was applied at Fengchi (GB 20), Tianzhu (BL 10) and Jiaji (EX-B 2) C3-C5. The chiropractic spinal manipulation was used in combination. In the chiropractic spinal manipulation group, the simple chiropractic spinal manipulation was adopted. The treatment was given once every other day in the two groups, 10 days made one session. One session of treatment was required. Visual analog scale (VAS) score was observed before and after treatment in the two groups and the efficacies were compared between the two groups.

RESULTSVAS score after treatment was reduced obviously as compared with that before treatment in the patients of the two groups (both P < 0.01) and VAS score after treatment in the combined therapy group was lower than that in the simple chiropractic spinal manipulation group (1.50 +/- 0.58 vs 1.87+/-1.05, P < 0.01). In the combined therapy group, 48 cases were cured, 20 cases remarkably effective, 8 cases improved and 0 case failed. In the chiropractic spinal manipulation group, 30 cases were cured, 16 cases remarkably effective, 15 cases improved and 1 case failed. The overall efficacy in the combined therapy group was better than that in the chiropractic spinal manipulation (P < 0.05).

CONCLUSIONThe sword-like needle therapy combined with chiropractic spinal manipulation relieve effectively pain in cervical type of CS and the efficacy is superior to the simple chiropractic spinal manipulation.

Objective To analyze the cause of acute brain swelling,brain encephalocele in brain traumatic injury craniotomy,and the reason,diagnosis and treatment methods of progressive epidural hematoma.Methods The clinical data of 381 patients with brain traumatic injury craniotomy were retrospetively analyzed.Of 318 patients,27cases had progressive epidural hematoma during operation.Results 9 cases died because of functional failure of brain stem,the other 18 cases were all clinically cured.Conclusion If acute brain swelling and encephalocele occured during operation,the cause should be found quickly,especially when there was skull fracture or epidural hematoma on the contralateral brain,the head CT and operation should be taken immediately,and the bulging brain tissue should not be removed blindly,and the skull should not be forced to close,otherwise the prognosis maybe poor.

Objective To develop rats model for human dilated cardiomyopathy(DCM).Methods Male Sprague-Dawley rats were administered adriamycin intraperitoneally 2.8 mg/kg? week)for 11 weeks,and then observed for 2 weeks.Plasma levels of brain natriuretic peptide(BNP)were studied by ELISA;left ventricular end diastolic diameter(LVEDD),left ventricular end systolic diameter(LVESD)and left ventricular ejection fraction(LVEF)were measured by echocardiogram;and morphology of the hearts and pathological lesions of cardiac muscle tissues were observed.Results(1)The levels of BNP of the DCM group were higher than those of the normal group(P

OBJECTIVETo investigate cell apoptosis, mitochondrial membrane potential, cytochrome C and mechanisms of mitochondria in lymphocyte apoptosis of sepsis.

METHODSIn the research, female C57BL/6 mice whose body weight ranged from 17 to 25 grams were utilized and assigned randomly to two groups: sham operated group (Control), cecal ligation and puncture group (CLP). The present study was undertaken by using the mice splenic lymphocyte to investigate cell apoptosis, mitochondrial membrane potential, cytochrome C. The apoptosis alteration was evaluated by Annexin V-FITC/PI double staining with flow cytometry. The alteration of mitochondrial membrane potential was investigated by Rhodamine-123 staining of cells. Cytochrome C of mitochondria and cytosol was investigated by Western blot methods. Statistical analysis was performed using SPSS 11.5 for Windows software. Experiment data was indicated with mean ± standard.

RESULTSThe splenic lymphocyte apoptosis was significantly accelerated in the CLP group when compared with that in control group (17.3% ± 2.2% vs. 3.5% ± 0.5%, P < 0.05). The Rhodamine-123 fluorescent intensity in splenic lymphocyte apoptosis was reduced in CLP group (76.2% ± 1.6%). Comparison between sham group (99.6% ± 0.4%) and CLP group had statistical significance (P < 0.05). Apoptosis could induce mitochondrial cytochrome C release into cytoplasm. In the CLP group, elevation of cytochrome C in cytosol was concurrently in accordance with decline in mitochondrial cytochrome C content.

CONCLUSIONThese data suggest that mitochondria and mitochondria signal pathway play an important role in lymphocyte apoptosis of sepsis.

BACKGROUNDTo explore the clinicopathological changes of non-small cell lung cancer tissues after neoadjuvant chemotherapy with MVP (MMC+VDS+DDP) regimen and its concordance with clinical evaluation, and to study the clinical value of neoadjuvant chemotherapy.

METHODSA total of 84 patients with NSCLC were randomized into combinated therapy group (42 cases) and surgical group (42 cases). The combinated therapy group were given MVP regimen for 2 cycles before operation and 2-4 cycles after operation, however, the surgical group only received surgical treatment. The efficacy of preoperative chemotherapy were determined by pathologic examination under light microscope and electron microscope and clinical evaluation.

RESULTSCombinated therapy group showed various degrees of degeneration and necrosis of tumor cells, which was not found in surgical group. The overall response rate of neoadjuvant chemotherapy was 59.5% (25/42) by both pathological and clinical evaluation. The coincidence ratio of the two evaluation methods was 71.4% (Kappa value=0.407,P < 0.01). Between the two groups, there was a significant difference in total survival rate (P=0.047). And further analysis showed that survival rate was remarkably different in patients with stage III between the two groups (P=0.037), but not in those with stage I and II (P > 0.05).

CONCLUSIONSDegeneration and necrosis with fibrosis are the main pathological phenotypes of the primary lesion after induction chemotherapy, which can be showed by clinical evaluation to chemotherapy efficacy. The preoperative and postoperative adjuvant chemotherapy may be benefical to patients with stage-III NSCLC.
