Temporal and spatial expressions of ?-catenin investigated in the hair follicle and epidermis of the hoof periphery in bovine embryonic development. IHC (immunohistochemical method) was applied to qualitatively detect the temporal and spatial expressions of ?-catenin. ?-catenin was detected in suprabasal, epidermal basal layer, placode, hair bud in early phase(E68~93),and expressed strongly in epidermal basal layer, placode, and hair bud, in suprabasal expressed less strongly; in metaphase(E94~184), ?-catenin was detected in epidermis, hair peg, and in suprabasal, epidermal basal layer, hair follicle bulge, inner root sheath, outer root sheath, follicular infundibulum expressed less strongly; in late phase(E184~225), ?-catenin expressed weakly in epidermal basal layers, while expressed strongly in epidermal keratinocytes. The result suggested that ?-catenin plays an important role in hair follicle morphogenesis in the periphery of bovine hoof in bovine embryos.

Objective To explore the protective effect and the mechanism of fastigial nucleus electric stimulation on brain of rats with hypoxic-ischemic brain damage(HIBD).Methods Ninety rats were randomly divided into 3 groups:sham operated group(n=30),model group(n=30)and electric stimulation group(n=30),every group was divided into group A(n=10),group B(n=10)and group C(n=10)again.The models of perinatal HIBD rats were prepared by ligation of left common carotid artery with a temporary systemic hypoxia(N2O2 was 928)for 2 hours.Electric stimulation group was used electric stimulation for 20 minutes,2 times everyday after surgery.The sham operated group and model group was not used electric stimulation but catched to fix in corresponding period.All of the group A would be injected bromodeoxyuridine(BrdU)to enterocoelia before 8 hours when the rats would be killed and the group B would be not injected it.The rats of the group A and B would be killed and got the brain tissue after cardiac perfusion 7 days later,then,consecutively coronal slice.The changes of BrdU and nestin levels in brain were observed by immunohistochemistry staining assay.And the study and memory ability of all the group C would be tested by maze test after 28 days.The brain tissue would be tested by hematoxylin and eosin stain at the same time.All of the data would be described and analyzed by SPSS 13.0.More than a few means would be compared by One-Way analysis of variance and the t-test between 2 groups would be used.Results The BrdU and nestin levels of the model group were lower than the sham operated group(Pa

Objective To determine the effect of video-assisted retroperitoneal debridement in treatment of infected necrotizing pancreatitis.Methods The clinical data of patients with infected necrotizing pancreatitis was retrospectively analyzed.Heart rate,mean arterial pressure,body temperature and indicators for inflammatory response including level of WBC,CRP and procalcitonin before and after VARD treatment were compared.Results After VARD treatment,the heart rate (preoperative vs.postoperative 8 h,108 ± 22/min vs.95 ± 17/min),mean arterial pressure (preoperative vs.postoperative 12 h,66 ± 18 mmHg vs.79 ± 19 mmHg) and body temperature(preoperative vs.postoperative 24 h,38.3 ± 1.7 ℃ vs.37.3 ± 1.3 ℃) improved significantly (all P < 0.05).Level of WBC [preoperative vs.postoperative 48 h,(13.8 ±6.6) × 109/L vs.(10.1 ±5.2) × 109/L],CRP(preoperative vs.postoperative 48 h,145 ± 88 mg/L vs.95 ± 4 mg/L) and procalcitonin (preoperative vs.postoperative 48 h,1.4 ± 0.7 μg/L vs.0.9 ± 0.4 μg/L) also decreased significantly(all P < 0.05).Conclusions VARD therapy can significantly reduce systemic inflammation and improve the general condition of infected necrotizing pancreatitis patients.

Objective To determine the effects of cyclooxygenase-2 (COX-2) on risk stratification and prognosis of patients with gastrointestinal stromal tumor (GIST).Methods Literatures in the Cochrane libraries of clinical comparative trials,PubMed,EMBASE,Cancer Lit and Chinese BioMedical Literature from 1966 to 2012 were retrieved using the Cochrane systematic evaluation method.The original data were extracted and crosschecked by 2 reviewers.The indicator for assessment including positive rates of COX-2 in GIST patients with different tumor diameters (<5 cm versus ≥5 cm),mitosis of cancer cells (<5/50 HPF versus ≥5/50 HPF) and National Institute of Health (NIH) risk stratifications (very low + low versus intermediate + high).The relationship between COX-2 expression and recurrence and metastasis of GIST was evaluated.All the data were analyzed using the RevMan 5.1 software with Meta analysis.The heterogeneity between studies was analyzed using the I2.The binary data were presented by odds ration (OR) and 95% confidence interval (95 % CI).Results Seven articles with a total of 415 patients were included in the analysis.The COX-2 expression did not correlate with the tumor diameters,NIH risk stratifications and tumor metastasis and recurrence (OR =0.60,0.72,2.46,P > 0.05),but with the mitosis of cancer cells (OR =0.46,P < 0.05).Conclusion COX-2 expression is partly correlated with risk stratification of GIST,but has no effect on the prognosis.

A sensitive, rapid and specific liquid chromatographic-tandem mass spectrometric (LC-MS/MS) method for quantification of gabapentin in human plasma has been developed. After a single plasma protein precipitation with methanol, gabapentin and metformin (internal standard) were chromatographed on a Inertsil ODS-3 column (50 mm x 2.1 mm ID, 3 microm) with mobile phase consisting of methanol-0.2% formic acid aqueous solution (80:20, v/v) at a flow-rate of 0.2 mL x min(-1). Electrospray ionization (ESI) source was applied and operated in the positive ion mode. Multiple reaction monitoring (MRM) mode with the transitions of m/z 172 --> m/z 154 and m/z 130 --> m/z 71 were used to quantify gabapentin and metformin, respectively. The run time was 2.2 min. The linear calibration curve was obtained in the concentration range of 40.8-8.16x10(3) ng x mL(-1). The lower limit of quantification was 40.8 ng x mL(-1). The intra- and inter-day precision (RSD) was less than 12%, and the accuracy (RE) was within +/-6.4% calculated from quality control (QC) samples. The method was used to determine the concentration of gabapentin in human plasma after a single oral administration of 600 mg gabapentin capsule to 20 healthy male Chinese volunteers. The method was proved to be selective, sensitive, rapid and suitable for pharmacokinetic study of gabapentin in human plasma.

Objective To examine the application value of reticulocyte hemoglobin content (CHr)for diagnosing iron deficiency in premenopausal women.Methods The levels of CHr,hemoglobin (Hb), mean cellular volume(MCV),red cell distribution width (RDW) were measured on the ADVIA 120 (Bayer Diagnostics) automated hematology analyzer.Transferrin saturation (TS) and ferritin (SF) were measured on chemistry analyzer.Results CHr in iron deficiency without anemia group were significantly lower than that in the healthy control group (P<0.01)and significantly higher than that in iron deficiency anemia group(P<0.01).CHr in anemia of chronic disease group were significantly higher than that in iron deficiency anemia group(P<0.01).Receiver operator characteristic curve (ROC) analysis in diagnosis of iron dificiency without anemia demonstrated that the area under the curve for CHr,SF,RDW,MCV,Hb were 0.872,0.798,0.721,0.713,0.677,respectively (P<0.01).So CHr has a better overall sensitivity than SF,Hb,MCV and RDW in the diagnosis of iron deficiency without anemia.ROC also showed that the area under the curve for Hb,RDW,CHr,SF and MCV was 1.000,0.969,0.958,0.953 and 0.926,respectively (P<0.01) in iron deficiency anemia.Conclusion CHr is the early and sensitive predictor of iron deficiency in premenopausal women,especially for the diagnosis of iron deficiency without anemia.
