Objective To explore the clinical effect of escitalopram combined with xingnaojing in post-stroke depression (PSD).Methods Seventy-four cases with PSD were divided into treatment group (38 cases) and control group (36 cases) by random digits table,control group was given escitalopram,treatment group was given escitalopram and xingnaojing.Hamilton depression scale (HAMD),mental state examination (MMSE),memory quotient (MQ) and activities of daily life (ADL) score,clinical curative effect and adverse reaction were compared between 2 groups.Results The HAMD,MMSE,MQ,ADL score after treatment in 2 groups were significantly better than those before treatment [control group:(14.26 ± 2.61)scores vs.(29.73 ± 5.17) scores,(23.26 ± 3.75) scores vs.(21.24 ± 3.38) scores,(86.53 ± 6.49) scores vs.(82.35 ± 5.42) scores,(61.37 ± 3.72) scores vs.(45.32 ±4.48) scores;treatment group:(10.31 ± 2.08)scores vs.(29.57 ± 6.09) scores,(27.83 ± 4.31) scores vs.(21.63 ± 3.82) scores,(95.63 ± 6.41) scores vs.(82.30 ± 7.48) scores,(69.15 ± 6.39) scores vs.(45.27 ± 4.28) scores,P ＜ 0.05].The HAMD,MMSE,MQ,ADL score after treatment in treatment group were significantly better than those in control group (P ＜0.05).The total effective rate in treatment group was significantly higher than that in control group [97.4％(37/38) vs.86.1％(31/36),P ＜ 0.05].There was no significant difference in rate of adverse reaction between 2 groups (P＞ 0.05).Conclusion Escitalopram combined with xingnaojing in PSD is effective and safe,and worth further clinical application promotion.

Objective To observe the effect on the patients of diabetes mellitus and cerebral infarction in terms of level of blood rheology and endothelin after using both intravenous low intensity laser irradiation (ILILI) and traditional Chinese medicine Tangnaoluotong in the treatment. Method Ninety patients of diabetes mellitus and cerebral infarction, having the symptom of deficiency in both vital energy and yin with blood stasis, were divided into three treatment groups at random:ILILI group (A), TCM treatment group (B), and a group with compound treatment of ILILI and TCM (C). The level of blood rheology and endothelin were observed after 1 month’s treatment. Result Compared with group A and group B, group C could significantly reduce the level of fibrinogen and endothelin, improve the deformed ability of RBC. Conclusion ILILI with Tangnaoluotong can significantly alter the blood rheology and endothelin on the patients of diabetes mellitus and cerebral infarction, which result in a better curative effect.

Objective To determine the relationship between the polymorphism of D2S140 gene and type 2 diabetes mellitus.Methods D2S140 region polymorphism were analyzed with the polymerase chain reaction and short tandem repeat methods in 103 subjects with type 2 diabetes mellitus and 105 nondiabetic subjects.All subjects were biologically unrelated Chinese without a family history of DM.Results There were 7 alleles ranging from 151bp to 163bp in all subjects.The frequencies were 0.01 to 0.37,2 alleles were more common in diabetic patients than in nondiabetic subjects (RR=16.04, P

Objective To evaluate the level of granzyme B mRNA and perforin mRNA in urine on the diagnosis of renal acute rejection. Methods A total of 34 cases of renal transplantation were studied.The urine samples were measured with the use of a competitive and quantitative polymerase-chain-reaction assay for granzyme B mRNA and perforin mRNA and the data were analysed by using the SPLM statistical software,mRNA levels were log-transformed. Results The levels of granzyme B mRNA and perforin mRNA in urine were higher in patients with acute rejection than in patients without acute rejection.The level of perforin mRNA in patients with acute rejection was (1.2?0.4)fg/?g of total RNA and in patients without acute rejection was (-0.6?0.3)fg/?g of total RNA (P

0.05].The mean follow-up of 45 pat ients is 36(1～76) months.No local tumor recurrence has been noted. C onclusionsNSS can be performed with satisfactory result in RAML,and it is the first choice of surgical treatment.

Objective To reproduce an experimental model of blast injury to dog brain simulating the mechanism of primary effect of the blast wave of explosive weapons.Methods A spherical explosive with explosive energy of 1gTNT was used to detonate at different distances(9mm,13mm)from the right temple to produce blast injury to the dog brain.The changes in physiological index before or after detonating and the surviving time after injury were recorded.The changes in the behavior of the wounded animals and characteristics of pathological changes in the brain were observed.Results Respiratory arrest,hypotension,and decreased heart rate were observed after wounding.All animals survived longer than 6 hours after the explosion injury.Obvious subdural hematoma and sub-arachnoid hemorrhage occurred frequently.Traumatic conditions of the brain were different in the two groups.Conclusions The animal model reproduced in this experiment simulates that produced by blast wave of explosive weapons.It is reproducible,easy to handle,and can be used in experimental study of blast injury to the brain.

Objective To investigate the relationship between polymorphisms of candidate genes 〔glucokinase (GCK) gene, NIDDM1(D2S140) gene, fatty acid bindingprotein2(FABP2)gene〕and type 2 diabetes mellitus (DM) in Shandong Chinese Han population. Methods Short tandem repeat (STR) region polymorphisms of GCK gene, NIDDM1 gene and FABP2 gene were analyzed with the polymerase chain reaction and polyacrylamide sequencing gel in 107 patients with type 2 diabetes mellitus and 105 normal subjects. The subjects studied were unrelated and they are Chinese Hans living in Shandong province and no diabetes family history was revealed. Results A5 allele of GCK gene and B2 allele of NIDDM1 gene were positively related with type 2 diabetes (RR=15.70, P0.05). Logistic regression analysis showed that A5 allele and B2 allele were among the risk factors of type 2 diabetes. Conclusion Polymorphic microastellite repeat markers at the glucokinase gene and the NIDDM1 (D2S140) gene locus are associated with type 2 diabetes in Chinese. The polymorphism at the FABP2 locus is not a genetic marker for type 2 DM in Chinese Hans.

Objective To study the effect of atlantoaxial pedicle and lateral mass screw in treat-ment of atlantoaxial instability. Methods A retrospective analysis was done on 11 eases of aflantoaxi-al instability treated with atlantoaxial pedicle and lateralmass screw from June 2006 to December 2007. Results The postoperative radiographs verified good position of all screws, with satisfactory atlantoaxial reduction. Follow-up for 3-21 months (average 12 months) showed no spinal cord and vertebral artery in-jury or interfixation failure. Conclusion Atlantoaxial pediele and lateral mass screw technique is a convenient method with solid fixation for treatment of atlantoaxial instability.

Objective:To investigate the expressions of peripheral lymph node addressin(PNAd)andGlcNAc-6-sulfotransferase(GlcNAc6ST)in endometrium and their impacts on implantation.Methods:PNAd expression in endometrium was examined by immunohistochemistry and Western Blot from 75women(12 from healthy women,in proliferative phase;63 from sterile women,of whom,27 were inearly-secretory and 36 in mid-secretory phase).GlcNAc6ST mRNA was examined by real-time PCR in41 sterile women.The 63 sterile women had underwent ⅣF-ET and were consequently divided into clini-cal pregnant(29 cases)and nonpregnant(34 cases)groups.Results:(1)PNAd localized to the mem-brane and cytoplasm of luminal and glandular epithelia.Staining was patchy and much less intense duringthe proliferative phase than during the secretory phase.In Western Blot of PNAd,four bands appeared,which were Sgp200,CD34,MAdCAM-1,GlyCAM-1 respectively,and each was positively correlatedwith the others significantly.The former three molecular levels were significantly higher during the secre-tory phase as compared with the proliferative phase.Message RNA of GlcNAe6ST was positive in all ca-ses and showed no correlation with any component of PNAd.(2)The expressions of CD34 and GlyCAM-1,but not Sgp200 and MAdCAM-1,were significantly higher in pregnant women than in nonpregnantones.However,the GlcNAc6ST mRNA level did not differ between groups.(3)No significant differ-ence was found in female age,methods of fertilization,thickness of endometrium on day hCG,cumulativeembryo score(CES)and mean score of transferred embryo(MSTE)between the groups.Conclusion:PNAd expression in the human endometrium fluctuates with the menstrual cycle.Elevated CD34 and Gly-CAM-1 during the secretory phase might be stimulative factors for embryo implantation.Defect in PNAdexpression may account for a portion of unexplained infertility.
