ALM To study the effects of ginkgo biloba extract (GbE) on expressions of neuron specific enolase (NSE) and S 100 protein(S 100) mRNA in newborn rat brain after hypoxic ischemic brain damage (HIBD) and the mechanism of GbE against HIBD. METHODS The dynamic changes of expressions of NSE S 100 mRNA in brain tissue and effects of GbE were studied using 7 d SD rat hypoxic ischemic brain damage model and RT PCR techniques. RESULTS The peak expressions of mRNA for NSE and S 100 occurred 24 and 48 hours after HIBD respectively, and their expressions decreased gradually. The expressions of mRNA for NSE S 100 in 24, 48, 72 hours were increased after treatment with GbE ( P

Objective To study the general rule in the power spectrum percentage of balance when normal people standing and the differences of the power spectrum percentage between normal people and the stroke patients. Methods 30 normal people and 30 stroke patients was tested with Active Balancer EAB-100 (Sakai Iryo) open- and close-eye. The whole path length, circumference area and the percentages of power spectrum on the X, Y and Z axes were recorded. The correlation and the differences were analyzed. Results The percentages of power spectrum were not statistically correlated (P>0.05) with age, height, weight or gender. There was significant difference between two groups in the percentage of power spectrum (P<0.05). On the frequency spectrum, the ratio rised on the low and middle frequency part, especially within 0.2~2 Hz, but the ratio decreased on the high frequency part (2~10 Hz) (P<0.05). Conclusion The percentage of power spectrum can be an important reference in assessing the stroke patients' balancing functions.

OBJECTIVETo study the numbers and locations of spermatic veins, testicular arteries, and lymphatic vessels in the spermatic cord of the varicocele patient under the laparoscope.

METHODSFifty-seven varicocele patients received laparoscopic ligation of spermatic veins, during which we recorded the numbers and observed the locations of spermatic veins, testicular arteries, and spermatic lymphatic vessels.

RESULTSDuring the surgery, we identified 3.3 ± 1.2 spermatic veins, 1.4 ± 0.9 testicular arteries, and 4.3 ± 1.1 spermatic lymphatic vessels. No statistically significant differences were observed between the two side in the numbers of the spermatic veins, testicular arteries and spermatic lymphatic vessels (P > 0.05). The testicular arteries were seen on the exterior of the spermatic veins and winding around them, while the spermatic lymphatic vessels mostly between the veins.

CONCLUSIONThe spermatic veins, testicular arteries, and lymphatic vessels in the spermatic cord of the varicocele patient have their specific anatomic characteristics. Laparoscopic identification of these vessels may contribute to the surgical treatment of varicocele.

Objective To evaluate the value of 99Tcm-MDP uptake by left femoral neck for diagnosing osteopomsis.Methods A total of 58 cases (23 males,35 females,mean age:(66.15±8.45) years) with spondyloarthmpathies from May to December of 2012 were selected.Serum concentrations of type Ⅰ collagen telopeptide (sCTX-1) and bone ALP (BALP) were determined.All patients underwent dual-energy X-ray absorptiometry (DXA) to detect bone mineral density (BMD).According to the T scores,patients were divided into 2 groups:normal group (NG) (T＞-1.0) and osteoporosis group (OG) (T≤-2.5).99TcmMDP bone scan was further performed.The average radioactive ratio of the left femoral neck to the medial soft tissue of left femur (T/N) was measured.Data differences between the 2 groups were compared by twosample t test and Pearson correlation analysis.Results According to BMD,13 patients (7 males,6 females) were included in NG and 28 patients (10 males,18 females) were included in OG.The mean ages of OG and NG were significantly different ((68.82± 10.41) years vs (62.46± 11.77) years; t =3.560,P＜0.05).The BMD of left femoral neck in OG was significantly lower than that in NG ((0.67±0.08) g/cm2 vs (0.91±0.10) g/cm2 ; t=9.917,P＜0.01).Although BALP level of OG was significantly higher than that of NG ((35.92±11.58) U/L vs (22.38±6.34) U/L; t=-3.397,P＜0.05),no significant difference was observed on sCTX-1 between the 2 groups (t=-0.463,P＞0.05).T/N ratio of OG (11.63±6.22) was higher than that of NG (9.74±4.44) (t =-3.027,P＜ 0.05).There were significant correlations between the T/N ratio of the left femoral neck and the sCTX-1 and BALP concentrations (r=0.376,0.483,both P＜0.01).No correlations between the T/N ratio of the left femoral neck and age,BMI and BMD were observed (r=-2.031,-0.017,0.134,all P＞0.05).Conclusion The uptake ratio of the left femoral neck in 99Tcm-MDP bone scan could evaluate the metabolism of bone,and it is useful for the early diagnosis of osteoporosis.

Objective To study MRI findings of pancreatic ducts of piglets with chronic pancreatitis (CP) induced by pancreatic duct ligation and analyze the relationship between pancreatic duct changes in piglets with CP and the pathological severity of CP. Methods Thirty healthy piglets were included in this study. Five piglets were randomly selected as normal control group, and the remaining 25 piglets were served as the experimental group. The duct ligation operations were performed on experimental group. After 2 to 18 weeks, pancreas and pancreatic ducts were observed on MRI. Then the pancreas was removed and graded into three types by histopathology. The relationship between the diameter of pancreatic duct or the pancreatic branch displaying rate and the severity of CP was analyzed by Spearman correlation coefficient. Results CP was found in 21 piglets( 84. 0% ) in the experimental group including mild ( n = 7 ), moderate ( n = 8 ) and severe( n = 6) pancreatitis. Pancreatic ducts were shown in mild CP and the edge of pancreatic ducts was irregular in three cases. The dilated RPD, LPD and MPD constituted the "person" form in moderate and severe CP. The diameter of pancreatic ducts was(0. 9 ±0. 3)mm, (2. 9 ± 1.4)mm and (4. 8 ± 1.2)mm in mild, moderate, and severe CP respectively. The expansion extent of pancreatic ducts was correlated with the severity of CP of piglets (r = 0. 837, P ＜ 0. 05). The pancreatic branch displaying rate increased with the increase of the severity of CP ( r = 0. 990, P ＜ 0. 05 ); the displaying rate was 0/7 for mild, 3/8 for moderate, and 5/6 for severe CP. Conclusions The dilated pancreatic ducts with "person" form in piglets with obstructive CP created by pancreatic duct ligation. The pancreatic duct changes on MRI reflect the severity of CP of piglets.
