OBJECTIVETo investigate clinical effects of auricular acupoint (AA) in the treatment of analgesia during perioperative period in total hip arthroplasty.

METHODSFrom March 2008 to August 2010, 60 patients with late osteonecrosis of the femoral head were treated by total hip arthroplasty and randomly divided into auricular acupuncture (AA) group and control group, 30 patients in each group. There were 11 males and 19 females in the AA group,with an average age of (60.93 +/- 5.90) years; the patients were treated with auricular acupuncture on the point of Shenmen, Subcortex, Kidney and hip joint for four times a week. There were 12 males and 18 females in control group, with an average age of (59.87 +/- 6.21) years; while the patients without auricular acupuncture. VAS score was used to evaluat the degree of pain; Harris score was used to evaluat the function of hip joint. All patients received patient controlled analgesia pump (PCA) for 48 hours after surgery (400 ml liquids were in PCA pump, including 800 mg tramadol and 0.8 mg fentanyl). The dosage of liquids and adverse reaction of PCA pump in different time were recorded.

RESULTSThe VAS score on the 3rd, 4th, 5th and 7th day separately was (3.61 +/- 0.29), (3.59 +/- 0.30), (2.97 +/- 0.26), (2.29 +/- 0.45), and lower than control group, which separately was (4.19 +/- 0.28), (4.00 +/- 0.31), (3.15 +/- 0.29), (2.83 +/- 0.31). The dosage of PCA in AA group separately was (72.27 +/- 8.06), (60.40 +/- 8.16), (44.13 +/- 4.75), (40.40 +/- 3.69), and less than control group, which was (86.27 +/- 8.51), (73.87 +/- 8.32), (54.53 +/- 5.20), (44.67 +/- 6.31) on the time of 0-12, 12-24, 24-36 h and 36-48 h after surgery. During the using of PCA, nausea and vomiting occurred in 5 cases, less than control group (21 cases). Harris score in AA group (78.90 +/- 5.14) was higher than control group (73.37 +/- 5.99) 2 weeks after operation.

CONCLUSIONAuricular acupuncture can reduce postoperative pain, reduce the usage of analgesic and complications, such as nausea and vomiting, improve the function of hip joint after operation.

OBJECTIVETo investigate the protective effect of Yigan Fuzheng Paidu Capsules (YC) combined with medical ozone against hepatic injury in dogs induced by hepatotoxic drug.

METHODSTwenty-four dogs were randomized equally into 4 groups (n=6), namely the model group, oleanolic acid tablet (OAT) group, YC group and YC+O(3) group, given either no particular treatment, oral OAT at 10 mg/day, oral YC at 0.2 g/day, or YC at 0.2 g/day plus 150 ml medical ozone transrectal insufflation every other day, respectively, for totally 30 consecutive days. Acute hepatic injury was induced after the treatment in the dogs with a sing-dose intraperitoneal injection of 0.9 ml/kg CCl(4) and peanut oil mixture (1:1, W/W). The general condition, survival time, alanine aminotransferase (ALT), aspartate aminotransferase/alanine aminotransferase (AST/ALT), serum total bilirubin (TBIL), prothrombin time (PT), blood ammonia (AMMO), and blood urea nitrogen (BUN) were recorded or measured. The hepatic pathological changes were observed upon death or on day 15 following CCl(4) injection.

RESULTSCompared with the other 3 treatment protocols, YC plus O(3) showed favorable effects on the activity, mental state, diet, urination and defecation of the dogs, which had significantly higher survival rate and higher levels of ALT, TBIL, PT, and AMMO than the model and OAT groups (P<0.05). AST/ALT remained normal in YC+O(3) group, which had also milder hepatic injury than the other 3 groups.

CONCLUSIONSYC combined with medical ozone may decrease transaminase and blood ammonia levels, relieve jaundice, prolong the survival time of dogs with CCl(4)-induced hepatic injury.

OBJECTIVETo summarize the experience in microsurgical removal of craniopharyngioma using combined transorbital-subfrontal and temporal craniotomy.

METHODSEighteen patients with craniopharyngioma varied from 3.1 cm to 6.2 cm in diameter. The tumor was located in the suprasellar region in 7 patients, extended to the third ventricle in 6, and down to the intrasellar from the suprasellar region in 4, and in the third ventricle in 1. Complete or partial cystic tumor was seen in 13 patients, and solid tumor in 5, and calcified tumor in 12. All the patients were operated on via combined transorbital subfrontal and temporal approach. The tumor was dissected in the spaces I, II and IV with great attention to the preservation of the perforating arteries from the carotid, posterior communication and anterior choroidal arteries to the structure of the hypothalamus. The solid portion of the tumor was removed by piecemeal.

RESULTSThe tumor was totally removed in 14 patients and subtotally in 4. Postoperation, follow-up for 8 to 41 months showed no change in 3 residual tumors and one lost to follow-up. All patients Postoperative Karnofsky scales showed 80 - 90, in 12 patients, 60 - 70 in 5 patients, and 50 in 1.

CONCLUSIONSCombined transorbital-subfrontal and temporal approach can provide an excellent exposure to the sellar region, craniopharyngioma and its surrounding structures. This approach ensures less cerebral retraction for easy access to craniopharyngioma, including other large neoplasm of the middle cranial base with ventricle or posterior cranial base extension. Microsurgical techniques play an important role in removing tumor and preserving hypothalamic function.

BACKGROUNDFunctional electrical stimulation (FES) is known to promote the recovery of motor function in rats with ischemia and to upregulate the expression of growth factors which support brain neurogenesis. In this study, we investigated whether postischemic FES could improve functional outcomes and modulate neurogenesis in the subventricular zone (SVZ) after focal cerebral ischemia.

METHODSAdult male Sprague-Dawley rats with permanent middle cerebral artery occlusion (MCAO) were randomly assigned to the control group, the placebo stimulation group, and the FES group. The rats in each group were further assigned to one of four therapeutic periods (1, 3, 7, or 14 days). FES was delivered 48 hours after the MCAO procedure and divided into two 10-minute sessions on each day of treatment with a 10-minute rest between them. Two intraperitoneal injections of bromodeoxyuridine (BrdU) were given 4 hours apart every day beginning 48 hours after the MCAO. Neurogenesis was evaluated by immunofuorescence staining. Wnt-3 which is strongly implicated in the proliferation and differentiation of neural stem cells (NSCs) was investigated by Western blotting analysis. The data were subjected to one- way analysis of variance (ANOVA), followed by a Tukey/Kramer or Dunnett post hoc test.

RESULTSFES significantly increased the number of BrdU-positive cells and BrdU/glial fibrillary acidic protein double- positive neural progenitor cells in the SVZ on days 7 and 14 of the treatment (P < 0.05). The number of BrdU/doublecortin (DCX) double-positive migrating neuroblast cells in the ipsilateral SVZ on day 14 of the FES treatment group ((522.77 ± 33.32) cells/mm(2)) was significantly increased compared with the control group ((262.58 ± 35.11) cells/mm(2), P < 0.05) and the placebo group ((266.17 ± 47.98) cells/mm(2), P < 0.05). However, only a few BrdU/neuron-specific nuclear protein-positive cells were observed by day 14 of the treatment. At day 7, Wnt-3 was upregulated in the ipsilateral SVZs of the rats receiving FES ((0.44 ± 0.05)%) compared with those of the control group rats ((0.31 ± 0.02)%, P < 0.05) or the placebo group rats ((0.31 ± 0.04)%, P < 0.05). At day 14, the corresponding values were (0.56 ± 0.05)% in the FES group compared with those of the control group rats ((0.50 ± 0.06)%, P < 0.05) or the placebo group rats ((0.48 ± 0.06)%, P < 0.05).

CONCLUSIONFES augments the proliferation, differentiation, and migration of NSCs and thus promotes neurogenesis, which may be related to the improvement of neurological outcomes.

OBJECTIVETo identify zebrafish mutants with myelopoiesis defects by ENU mutagenesis and large-scale forward genetic screening.

METHODSMale zebrafish were mutagenized with N-ethyl N-nitrosourea to induce mutations in the spermatogonial cells to generate the founders, which were outcrossed with AB to raise F1 fish. The F1 fish from different founders were mated to generate the F2 families. The F3 embryos from F2 sibling crosses were screened by Sudan black B staining and neutral red staining.

RESULTSA total of 350 F2 families from F1 sibling crosses were screened, and 1424 F2 crosses were analyzed. Six mutations were identified resulting in abnormal Sudan black B staining and neutral red staining, indicating the involvement of neutrophil deficiency or macrophage abnormalities.

CONCLUSIONIt is simple and cheap to induce and screen myelopoiesis deficiency in zebrafish by ENU chemical mutagenesis and Sudan black B staining and neutral red staining. These mutants shed light on the identification of the genes important to myelopoiesis in zebrafish.

OBJECTIVETo screen and identify zebrafish mutants with erythropoiesis defects by N-ethyl-N-nitrosourea (ENU) mutagenesis and large-scale forward genetic screening using beta e 1 as the marker.

METHODSThe chemical mutagen ENU was used to treat healthy wild-type male fish (AB strain, F0). The surviving ENU-treated fish were mated with wild-type female fish to generate F1, and further F2 family was generated by F1 family intercross. The adult F2 fish were intercrossed within each F2 family and the resulting F3 embryos from each crossing were subjected to whole mount in situ hybridization (WISH) with the beta e 1 probe. Mutagenesis was performed by treating the male zebrafish with ENU to induce mutations in pre-meiotic germ cells to generate the founders, which were outcrossed to obtained the F1 fish. The F1 fish from different founders were mated to generate the F2 families. F3 embryos from the sibling cross in the F2 family were examined by whole mount in situ hybridization using beta e 1-globin probe. The putative mutants were then characterized with different hematopoiesis markers.

RESULTS AND CONCLUSIONWe identified 4 beta e 1-deficient mutants with erythropoiesis defects, including two with specific erythiod lineage defects and two with concurrent lymphopoiesis defects.

Objective To determine whether the combination of traditional risk factors and quantitative coronary angiography (QCA) assessment could provide accurate prognostic information on a population-based study including 1137 adults with subclinical artherosclerosis and with coronary risk factors. Methods Participants underwent coronary angiography examination before the minimal stenotic diameters, segment diameters, percent stenosis, plaque areas. Other parameters were analyzed by the computer-assisted Coronary Angiography Analysis System. The Framingham Risk Score for each participant was assessed. During the 1 year follow-up period, all kinds of endpoint cardiovascular events were screened. Endpoint events were defined as death from coronary heart disease, nonfatal myocardial infarction (MI) or unstable angina pectoris. Results During the 1 year of follow-up period, a total of 124 participants developed an endpoint event, which was significantly associated with the Framingham Risk Score, calcium of plaques and the plaque areas (all Ps＜0.05).The QCA score incorporated with the QCA parameters was related to the endpoint events. The Framingham Risk Score was combined with QCA score through logistic regression for prediction of end-point events. Data from the ROC analysis showed the accuracy of this prediction algorithm was superior to the accuracy when variables themselves were used. The event-free survival rate was inferior to the control group in participates under high risk, when being screened with this prediction algorithm (P＜0.05). Conclusion The risk of cardiovascular attack in subclinical artherosclerosis individual seemed to be associated with the Framingham Risk Score, calcium of plaques and the plaque areas. When the traditional risk factors (the Framingham Risk Score) were combined with QCA, the new method could provide more prognostic information on those adults with subclinical artherosclerosis.
