OBJECTIVETo explore the effectiveness of absorbable hemostatic fluid gelatin in preventing postoperative cerebrospinal fluid leakage.

METHODSThe clinical data of 17 patients with dura mater tear were retrospectively analyzed from March to September in 2003. There were 16 males and 1 female, aged from 16 to 67 years old with an average of (39.6 ± 15.4) years. The injury site was at cervical vertebrae in 1 case, thoracic vertebrae in 9 cases, thoracolumbar junction in 4 cases, lumbar vertebrae in 3 cases. There were burst fracture in 4 cases and fracture-dislocation in 13 cases. According to ASIA grade, 12 cases were grade A, 2 cases were grade B, 2 cases were grade D, 1 case were grade E. Two cases caused by traffic accident, 10 by high falling, 4 by heavy parts crash, 1 by stairs fell during the earthquake. Absorbable hemostatic fluid gelatins were used to plug the dura mater tear,in order to prevent postoperative cerebrospinal fluid leakage. Postoperative drainage were recorded every day.

RESULTSOf 17 patients, 15 cases did not develop with cerebrospinal fluid leakage. Two cases develop with cerebrospinal fluid leakage after operation and their drainage were removed at 6 to 7 days after operation. In all cases, no complications related with cerebrospinal fluid leakage occurred, such as headache, dizzy, fever,neck resistance, rash, incision disunion, incision infection, hematoma, neurologic symptoms aggravation. No abnormal phenomena was found on incision surrounding at follow-up of 9 months.

CONCLUSIONUsing absorbable hemostatic fluid gelatin to plug the dura mater tear during operation is an effective method in preventing postoperative cerebrospinal fluid leakage.

AIMTo investigate the effect of 5-hydroxytryptamine (5-HT) on spontaneous unit discharges of primary somatosensory cortex (SI-SUD) and the role of 5-HT1A receptor in 5-HT inhibitory effect on SI-SUD in rat.

METHODSThe SI-SUD was recorded before and during microiontophoresis of 5-HT and 8-OH-DPAT (the selective agonist for 5-HT1A receptor. The changes of mean of interspike interval (MISI) of SI-SUD were analysed and handled with the statistics.

RESULTS(1) Effects of 5-HT on SI-SUD may be inhibitory (48/96), excitatory (26/96) or non-responsive (22/96), and the major effect is inhibitory. (2) In 20 of 5-HT inhibited units, 17 are also inhibited with microiontophoresis of 8-OH-DPAT, but 3 have no obvious response to 8-OH-DPAT.

CONCLUSIONThe major effect of 5-HT on SI-SUD is inhibitory. In majority of 5-HT inhibited units, 5-HT1A receptor may be existence, which may involve in the inhibition of 5-HT on SI-SUD.

OBJECTIVETo investigate the effects of alcohol intake on penile structure and function in rats.

METHODSThirty adult male Wistar rats were randomly divided into two groups: control group and alcohol intake group. They were administered with 2 mL of normal saline and 40% alcohol solution respectively through gastric tubes every day. Three months later, the animal model of alcohol intake was evaluated by modified Nayagida's method, and the effects of alcohol on the rats were studied by sexual behavior, the number of apomorphine-induced penile erection, level of testosterone in the sera, and the content of penile smooth muscle.

RESULTSThe scores of animal model of alcohol intake evaluated by Nayagida's method were 0.66 +/- 2.05 in the control group and 9.26 +/- 5.50 in the alcohol intake group (P < 0.05), which indicated that an animal model of alcohol intake was successfully established. Sexual behavior, the number of apomorphine-induced penile erection, testosterone level in the sera, and the content of penile smooth muscle of the alcohol intake group were all statistically different as compared with the control group (P < 0.05).

CONCLUSIONAlcohol intake induces sexual dysfunction in rats, which may be due to the decline of testosterone level in the sera and decline of penile smooth muscle.

Objective To explore the effect of improving clinical practice ability of nursing undergraduates via double evaluation.Methods From September 2015 to May 2016, 61 nursing undergraduates enrolled in 2012 to Guangzhou University of Chinese Medicine were selected by convenience sampling method and divided randomly according to their student number into experimental group (30 cases) and control group (31 cases). According to the double evaluation method adopted in the experimental group, clinical teaching scheme was modified dynamically. In the control group, clinical teaching was conducted according to clinical teaching scheme made by the university, with OSCE and evaluation form of clinical practice ability as tools for observer and self evaluation.Results Within the experimental group, both scores of observer evaluation in OSCE and scores of self evaluation in clinical practice behavior showed a trend of going up in phases (P<0.05). In comparison of observer evaluation in OSCE at the 9th month, scores of the experimental group were all higher than those in the control group in all dimensions except writing of nursing documents (P<0.05). In comparison of self evaluation in clinical practice behavior at the 9th month, scores of the experimental group were all higher than those in the control group in all dimensions except communication ability, slightly lower (P<0.05).Conclusions With the double evaluation method adopted, dynamically modified clinical teaching scheme according to phases can obviously improve clinical practice ability of nursing students.

OBJECTIVETo compare screw's inserting angle through the 11th and 12th rib in treating L1 burst fracture, explore effects on inserting screw and postoperative angle.

METHODSFrom October 2007 to October 2010, 108 patients with L1 brust fracture treated through anterior approach were analyzed,including 68 males and 40 females, aged from 21 to 64 years (mean 38.22 years). All patients were divided into the 11th (A, 51 cases) and 12th (B, 57 cases) approach. The data of operation time,blood loss, duration of incision pain, JOA score, Oswestry score, VAS score, quality of life (SF-36), recovery of nervous function, coronal Cobb angle, included angle between screw and plate were observed.

RESULTSAll patients were followed up for 9 to 37 months, mean 23 months. The operation time, blood loss, duration of incision pain, in group A were lower than group B (P<0.05), JOA score, Oswestry score, VAS score, SF-36, recovery of nervous function had no significant differences (P>0.05). There were no differences in Cobb angle before operation, but had significance after operation (P=0.000). There were statistically significance between two group in angle between screw and plate (P=0.000, P=0.003).

CONCLUSIONThe 11th rib approach for the treatment of L1 burst fracture has less effects on screw, less trauma and less angle between screw and plate.

OBJECTIVETo collect the data of measuring skin thickness of children of both genders of different ages and parts of body with non-invasive high-frequency ultrasound method.

METHODSTwo hundred and twenty-one children from 1 to 18 years of age,without systemic disease or injury in skin, were enrolled in the study and divided into 4 groups: i.e., infant group (112 years of age), pre-school age group (3-6 years of age), school age group (7-12 years for boys and 7-11 years for girls), adolescent age group (13-18 years for boys and 12-18 years for girls), and each group was subdivided into 2 groups according to the gender. The skin thicknesses of children in cheek, chest, abdomen, forearms, fundament and thigh was respectively measured by 13 MHz high-frequency ultrasound.

RESULTSThe region with thinnest skin in children was the cheek, and the thickest was the back and buttock. (1) There were no significant differences in thickness of skin in the same region between genders and also among different age groups (P > 0.05). (2) There were also no obvious differences of thickness of the dermis and the whole skin in the same region between male and female, or among infants, pre-school age and school age groups (P > 0.05). In adolescent group, the average thickness of dermis in male was (1.16 +/- 0.04 ) - (1.98 +/- 0.47) mm, the average whole thickness of skin in male was (1.27 +/- 0.12) - (2.20 +/- 0.45) mm, while those of female were (1.00 +/- 0.18) - (1.60 +/- 0.30) mm and (1.10 +/- 0.17) - (1.83 +/- 0.29) mm (P < 0.05).

CONCLUSIONIt is reliable to measure the skin thickness by 13MHz ultrasound as a non-invasive method. The main factor which determined the thickness of the skin is dermal thickness, especially in males. The significant differences of skin thickness among cheek, back and buttock provide the basis for us to choose the appropriate thickness of skin grafts harvested from different body parts.

Objective Transplantation of bone marrow mesenchymal stem cells (BMSCs) has a good prospect of application for cerebral infarction,but the environment and the inflammatory response to ischemia and hypoxia after cerebral infarction are not con-ducive to the survival of transplanted cells. This article investigated the effects of Shuxue Tongmai capsule(SXTM) combined with BM-SCs transplantation on the improvement of cerebral ischemic injury in rats. Methods A model of middle cerebral artery occlusion was es-tablished in Sprague-Dawley(SD) rats using thread method and these 15 SD rats were randomly divided into model group,BMSCs group and combination therapy group (BMSCs transplantation combined with SXTM treatment). At 24h after modeling,rats in combination therapy group were given tail vein injection of 1 mL BMSCs suspension (2× 109 per/L) and gavage administration of SXTM 0. 64 g/kg. Rats in BMSCs group were given tail vein injection of 1 mL BMSCs suspension (2×109 per/L) and gavage administration of equal volume of sa-line. For model group,the rats were given tail vein injection of equal volume of PBS and gavage administration of equal volume of sa-line. Neurologic function was assessed before cell transplantation and at 3,7,14,28 days after cell transplantation to check the injury of neurologic function. At 28 days after transplantion,the rats were decapitated after anesthesia to take brain tissues for immunohisto-chemical detection of vascular endothelial growth factor(VEGF) and brain-derived neurotrophic factor(BDNF) protein expression. Mor-phological changes of the brain tissue and apoptosis in cortical neurons were observed and detected by hematoxylin-eosin staining and TUNEL,respectively. Results At 7,14,28 days after transplantation,the neurological defect score in combination therapy group was significantly lower than those of model group and BMSCs group(P<0.05). In each group,the neurological defect score at 3 days after transplantation was significantly decreased compared with those before transplantation(P<0.05). In the same group,the neurologi-cal defect scores at 14,28 days after transplantation were significantly decreased compared with those at 7 days after transplantation (P<0.05). The neurological defect scores at 14,28 days after transplantation were significantly decreased compared with those at 7 days after transplantation(P<0.05). The neurological defect score at 28 day after transplantation was significantly decreased compared with that at 7 day after transplantation(P<0.05). At 28 day after transplantation,the number of apoptotic cells in combination therapy group (51.40±4.04) was significantly fewer than those of model group (74.80±5.31) and BMSCs group (67.20±4.66) and the num-ber of apoptotic cells in BMSCs group was significantly decreased compared with model group(P<0.05). The results of immunohisto-chemistry showed that the VEGF and BDNF positive cells in the cerebral ischemic region of rats were brownish or sepia in color. Com-pared with model group,the expression levels of VEGF and BDNF protein in BMSCs group and combination therapy group were signifi-cantly increased (P<0.05),and that of combination therapy group was significantly increased compared with BMSCs(P<0.05). Conclusion SXTM combined with BMSCs transplantation can promote neurological recovery from cerebral ischemia by increasing the protein expression of VEGF and BDNF and reducing neuronal apoptosis.

AIMTo study the biliary excretion of genistein and its metabolite at different doses in rats.

METHODSSuspended in 0.5% CMC-Na solution, genistein was orally administered to rats at the dose of 6.25, 12.5 and 50 mg x kg(-1), separately. At various time intervals, the bile was collected. The bile was treated with beta-glucuronidase. The genistein in bile was extracted twice by vortexing with 2.0 mL mixture of methyl tert-tubtyl ether and pentane (8:2). The organic phase was removed into the tubes and then evaporated in ventilation cabinet. The residue was dissolved in 50 microL of methanol. Twenty microL solution was drawn and detected by high-performance liquid chromatography.

RESULTSThe accumulative biliary excretion of genistein was (42.56 +/- 6.54) , (75.17 +/- 18.87) and (126.60 +/- 34.78) microg at the dose of 6.25, 12.5 and 50 mg x kg(-1), respectively. The total drug (genistein plus glucuronidated genistein) excreted from bile was (108.46 +/- 35.23), (423.46 +/- 158.31) and ( 853.74 +/- 320. 84) microg, and the ratio of glucuronidated genistein was 60.76% , 82.25% and 85.17% at the dose of 6.25, 12.5 and 50 mg x kg(-1), respectively.

CONCLUSIONThe genistein was excreted mainly in the form of glucuronidated genistein in rat bile. The genistein and glucuronidated genistein were excreted in a nonlinear dose-dependent manner.
