Objective To observe the effect of nursing intervention on children with hepatitis C receiving Kurorinone treatment.Methods 98 cases of children patients with hepatitis C admired from February 2008 to May 2010 were randomly divided into the intervention group (50 patients)and the control group(48 patients),all patients were treated with kurorinone for 3 months (one course of treatment),besides the intervention group received additional nursing.The liver function and serum HCV-RNA changes were compared between the two groups.Results Recovery of liver function in the intervention group was significantly better,negative rate of HCV-RNA in the intervention group was significantly higher than that of the control group.Conclusions Nursing intervention can improve treatment effect of kurorinone for children with hepatitis C.

OBJECTIVETo investigate the effects of E 4031, a sodium calcium exchanger (NCX) agonist, on the isolated cardiac function and resting Ca2+ level in myocardial cells from rats with chronic heart failure.

METHODSRats chronic heart failure model was established by abdominal aorta coarctation with; Isolated heart perfusion by Langendorff apparatus was used to detect heart function and the effects of E 4031 on haemodynamic indexes; Myocardial cells of rats in the model group were extracted quickly and co-incubated with calcium fluorescent indicator fluo3/AM and the impact of E 4031 on the fluorescence intensity in myocardial cells were evaluated by confocal microscopy.

RESULTSHeart function of rats in the model group detected by Langendorff perfusion was significantly reduced after 12 weeks, E 4031 at 10 micromol/L could improve their left ventricular developed pressure(LVDP) and systolic / diastolic maximum rate (+/- dp/dtmax). Compared with the control and sham operation groups, the resting Ca2+ fluorescence intensity of the myocardial cells of rats in model group was at a higher level and went through a process of transient rise and drop, then stably remaining at a low level after co-incubated with 10 micromol/L E 4031.

CONCLUSIONE 4031 can improve the isolated heart function of rats with chronic heart failure, which may be associated with its enhancing the activity of NCX in the myocardial cell membrane and stabilizing intracellular Ca2+ level.

OBJECTIVETo investigate the relationship between the second to the fourth digit ratio (2D:4D) and body mass index (BMI) in infertile men of the Han ethnic group in Ningxia.

METHODSUsing anthropometry, we calculated the mean ratio of 2D:4D and BMI of 197 infertile men and 148 normal healthy male controls, followed by analysis of their relationship.

RESULTSThe BMI was correlated positively with the 2D:4D ratio of the left hand in the infertile men (P < 0.05) and in the patients with a higher 2D:4D ratio of the left hand (P < 0.05), but negatively with the 2D:4D ratio of the righ/left (Dr-1) (left: P < 0.01; Dr-l: P < 0.05). The mean 2D: 4D ratio and BMI were both lower in the normal control than in the infertile men, with statistically significant differences in BMI (P < 0.05) and the 2D:4D ratio of the left hand (P < 0.05).

CONCLUSIONThere is a correlation between the 2D:4D ratio and BMI in infertile men.

Objective To investigate the role of autophagy and synaptophysin (SYP) in cognitive impairment in de?pressed rats receiving electroconvulsive shock (ECS). Methods Clean and healthy adult male Sprague-Dawley rats were acclimatized to a standard laboratory environment for 7 days. The chronic unpredictable mild stress (CUMS) was used to establish the rat model of depression. Behavior tests were conducted before and after CUMS to evaluate the depression and cognition level of rats. After establishment of the model, 24 rats were randomly divided into ESC group (group E) and depression group (group D) with 12 rats in each group. The rats in group E were administered 80 mg/kg of propofol (10 mg/mL) by intraperitoneal injection, followed by ECS treatment. The rats in group D were administered propofol by intra?peritoneal injection, followed by sham-ECS treatments. The above interventions were conducted daily for 7 consecutive days. After the interventions, rats underwent behavior tests as before. Subsequently, rats were killed and specimens were collected for measurements. Immunohistochemistry was performed to examine autophagy markers such as Beclin 1 and LC3Ⅱand ELISA was used to detect SYP in the hippocampus. Results Group E after ECS significantly increased the percentage of sucrose preference (68.2%±8.7%), rearing times (7.0±1.9), total horizontal distance [(569.5±70.0) cm], es? cape latency [(21.9±5.3)s] and space exploration time [(20.5±3.9)s] compared with group D or group E before ECS. There was no significant difference in these index between groups before ECS or in group E between before and after ECS(P>0.05). Compared with group D, group E had upregulated protein expression levels of Beclin 1 and LC3Ⅱin CA1, CA3, DG as well as the area near the hippocampus and increased SYP contents (P<0.05). Conclusions Cognitive impairment in depression rats following ECS correlates with activated autophagy and increased SYP by ECS.

AIM: To discuss the single application on iris localization technology in excimer laser for the treatment of astigmatism.
METHODS:Totally 203 cases (406 eyes) of laser in situ keratomileusis ( LASIK ) in the treatment of compound myopic astigmatism patients were operated from November 2011 to November 2012 in our hospital. They were divided into two groups. One was observation group using iris localization and the other was control group using routine operation. Patients in the observation group of 100 cases ( 200 eyes ) , aged 18-43 years old, spherical diopter was - 1. 25 to - 8. 75D, astigmatism was -1. 0 to -3. 25D. In control group, 103 patients ( 206 eyes ) , aged 19-44 years old, spherical diopter was -1. 75-9. 50D, astigmatism was -1. 0 to -3. 25D. The patients in the observation group before the application of WaveScan aberrometer check for iris image, spherical lens, cylindrical lens and astigmatism axis data operation, only single application of iris location, without using wavefront aberration guided technology, laser cutting patterns for conventional LASIK model, spherical, cylindrical mirror and astigmatism axis  RESULTS: Postoperative residual astigmatism, the observation group was significantly better than the control group. Astigmatism axial measurement after operation, the observation group was significantly less than that of the control group. Postoperative visual acuity at 6mo, the observation group was better than that of the control group. The difference was statistically significant.
data source to preoperative wavefront aberration results. The control group received routine LASIK. It was applicated comprehensive optometry optometry respectively to examine astigmatism and axial, based on the computer analysis during the preoperative, 1wk after the operation, and 6mo. Analysis of using SPSS 17 statistical software, it was independent-sample t test between the two groups of residual astigmatism and astigmatism axis.

In this paper 3 different media (A,for yeast cultivation ; B, for laccase producing; D, for white rot fungi cultivation) were compared in enriching and screening decolorizing fungi culture using Reactive Black 5 (RB5) and Reactive Red (M-3BE) from the following three points: decolorization effects, abilities of producing enzymes and diversity of microbial community. 11 groups of fungi with obvious decolorization effects were obtained after enrichment for near one month. Among them, 6 groups came from medium D, the other two 3 groups from medium A and B, respectively. However, the 3 groups from medium A exhibited the highest microbial diversity and best decolorization results with 99.53% and 97.42% color removal rate of Reactive Red M-3BE and Acid Red. From them, 16 strains of fungi were isolated and primarily identified as Saprolegniaceae, Eurotiaceae (Monascus went), Erysiphaceae and Physodermataceae. Fungi groups from medium B and D exhibited a bit lower color removal rate of various dyes and only 3 and 2 isolates primarily classified as Saccharomycetaceae and Eurotiaceae (Penicillium) were obtained from them. Fungi cultures in medium A and B could produce lignin peroxidase, and those in medium D could be detected higher activity of laccase. All the fungal cultures exhibited very weak activity of manganese dependant peroxidase.

Objective To investigate the effect of surgical treatment of adult mandibular condylar fractures (including intracapsular fracture). Methods Thirty-two patients (33 sides) with condylar fractures underwent open reduction and rigid fixation. Six patients with intracapsular condylar fractures were treated with two 18-mm positional screws through a preauricular approach. Six patients (7 sides) with condylar neck fractures were rigidly fixed by 1 mini-plate via a retromandibular transparotid approach. Twenty patients with subcondylar fractures were operated and fixed by two titanium plates using an angular approach. Results The mean follow-up period was 13.5 months, and the mean maximum mouth opening was 37.5 mm by the last visit. All patients acquired good occlusal relationship and mandibular symmetry. Seven patients (21.9%) experienced transient palsy of the branches of the facial nerve, and recovered completely after three months. One patient developed a salivary fistula, and healed after two weeks of gauze compression. No permanent deficit of any facial nerve branch was observed. No patient showed condylar head resorption. Conclusion Appropriate surgical approaches and fixation methods for different types of condylar fractures are the key factors to achieve reliable clinical results.

OBJECTIVETo investigate the effect of baicalein on the gap junction intercellular communication (GJIC) in the TM4 Sertoli cells of the mouse testis and its related mechanism.

METHODSWe measured the cytotoxicity of different concentrations of baicalein on the TM4 Sertoli cells in the mouse testis by MTT, detected the fluorescence transfer of the TM4 Sertoli cells by parachute assay, and determined the expression of the protein connexin 43 ( Cx43) in the baicalein-treated cells by Western blot and immunofluorescence assay.

RESULTSBaicalein produced no obvious cytotoxicity on the TM4 Sertoli cells at the concentration below 60 µmol/L but significantly increased their GJIC at 0-20 µmol/L (P < 0.01). Western blot and immunofluorescence assay showed that 0-20 µmol/L baicalein remarkably elevated the expression of Cx43 in the TM4 cells (P < 0.01) and on the membrane of the TM4 cells.

CONCLUSIONBaicalein at the concentration of 0-20 µmol/L can significantly enhance GJIC in mouse TM4 Sertoli cells by increasing the expression of the Cx43 protein.
