Objective:To investigate the chronic effect of topiramate on spatial learning and memory to young rats. Methods:P28 KA-induced rats were used. After 8-week treatment of topiramate, spontaneous recurrent seizures were recorded; Spatial learning and memory ability was evaluated by Morris water maze. Results: TPM-treated rats had significantly fewer(3.50?3.84) spontaneous recurrent seizures than rats without TPM treatment(7.36?3.75). On the first day of Morris water maze, they also had statistically longer latency to the platform(590.6?230.9 s) than those from the group without TPM treatment (422.6?122.3 s), but no latency differences were found in the following three days. TPM had no effect on water maze performance to rats without KA induction. After three days of interval, no differences were found in all groups under the same experimental situation.Conclusion:For developing rat brain, TPM has no impairment on the ability of long-term memory and information retrieval meanwhile its negative effect on spatial learning is temporary.

Objective To retrospectively analyze the main factors of abnormal umbilical blood flow in different stage after 24 weeks' gestation,and to evaluate its treatment outcomes.Methods 256 cases with abnormal umbilical blood flow were selected.The abnormality happened in different stages after 24 weeks' gestation and they were inspected and treated routinely.Latency factors of the different stage were analyzed to discover the primary reason,and the treatment outcomes were compared.Results The significant differences of constructional proportion were observed in different stage(x2 =25.60,P ＜ 0.05).The influence factors of different stages were as following:hypertension relative disease (33.33 ％) between 24 and 27 weeks' gestation,the umbilical cord factor (16.67 ％) ; the incidence rate of abnormal umbilical blood was 42％ between 28 and 36 weeks' gestation,including hypertension disease(28.70％),the umbilical cord factor(15.74％) ;umbilical cord (31.37％) between 37 and 40 weeks' gestation,although gestation period hypertension disease reduced,but still accounted for 22.54％,the placenta factor was 12.74％.After treatment,the cure rate had significant differences (x2 =11.16,P ＜0.01),89.58％ (24-27 week),80.55％ (28-36 week),69.60％ (37-40 week).Conclusion The hypertension relative diseases and abnormal cord are the primary factors which caused abnormal umbilical blood,24-37 gestation week is the key stage for the inspection and treatment,especially for the hypertension relative diseases.

Objective To investigate the level of human cytomegalovirus(HCMV)specific CD8+ T lymphoeytes in peripheral blood and the immune reaponae of HCMV reactivation after kidney transplantation.Methods Thirty-eight HCMV seropesitive HLA-A*0201 kidney transplant recipients(9 with HCMV infection and 29 without HCMV infection)and 54 healthy individuals were enrolled.The levels of total HCMV specific CD8+ T cells were measured using HLA-A2 pentamer folded with HCMV-peptide NLVPMVATV.The levels of IFN-γ secreting CD8+ T cells were measured by intracelluhr IEN-γ staining pulsed with the same peptide.Results The median levels of pentamer stained CD8+ T cells were 1.19%(0-19.42%),1.20%(0-18.40%)and 3.2%(0.51%-18.90%)in healthy group,negative HCMV group and positive HCMV group(H=5.34,P＞0.05),respectively.The median levels of IFN-γ secreting CD8+ T cells were 0.72%(0-0.70%),0.47%(0-5.61%)and 0.67%(0.07%-4.00%),respectively(H=0.58,P＞0.05).However,the mean proportions of IFN-γ secreting pentamer stained T cells relative to total HCMV specifc CIL were(60.18±19.16)%,(39.19±17.22)% and(20.02±13.26)%,respectively.There were significant differences among the groups(P＜0.01).Condusiorm There was no significant difference of levels of HCMV specific CD8+ T lymphocytes in peripheral blood between the kidney transplant recipients and healthy individuals.However,the proportion of HCMV-specific IFN-γ producing CD8+ T cells in pentamer stained cells was reduced in the kidney transplant recipients especially in those with active HCMV infection,which may contribute to the inability to control HCMV reactivation.

Objective To evaluate the efficacy of programmed intermittent epidural bolus ( PIEB) for labor analgesia in parturients and the effect on neonates. Methods Two hundred primiparae with a sin?gleton fetus in vertex presentation, who requested labor analgesia, aged 21-36 yr, at 37 to 40 week gesta?tion, with cervical dilatation 1-3 cm, of American Society of Anesthesiologists physical statusⅠ or Ⅱ, were divided into 2 groups ( n=100 each) using a random number table: PIEB group and continuous epi?dural infusion ( CEI) group. PIEB regimens were programmed as 10 ml∕h starting from 1 h after the initial bolus. The programmed bolus dose was fixed at 5 ml with the lock?out interval set at 30 min. The drugs used in the analgesic pump were 0?08% ropivacaine and 0?4μg∕ml sufentanil in both groups. From the on?set of labor analgesia until 1 h after delivery, visual analog scale score was used to evaluate the uterine con?traction pain every hour. The modified Bromage score was used to assess the degree of motor block. The up?per spread of sensory block, total consumption of drugs, the number of attempts, duration of every stage, delivery mode, postpartum hemorrhage volume, and occurrence of adverse reactions ( dyspnea, hypoten?sion, pruritus, nausea, vomiting and urinary retention) were recorded. Apgar scores of the neonates were recorded, and the degree of primiparae′satisfaction with the analgesic efficacy was scored. Results Com?pared with group CEI, visual analog scale scores at T2?5 , the total consumption of drugs and the number of
attempts were significantly decreased, and the satisfaction score was significantly increased in group PIEB ( P<0?05) . The height of sensory block in the thoracic vertebra was significantly higher, and the height of sensory block in the lumbosacral spine was significantly lower in group PIEB than in group CEI ( P<0?05) . There were no significant differences between the two groups in the duration of every stage, delivery mode, postpartum hemorrhage volume, incidence of adverse reactions and Apgar scores of neonates (P>0?05). Conclusion PIEB provides reliable efficacy for labor analgesia in parturients, the degree of primiparae′satisfaction is high without increasing the occurrence of adverse reactions, and it exerts no effect on the neonates.

Objective To evaluate the performance of a DNA microarray method for detecting HBV antiviral drug-resistant mutations. Methods Two hundred and twenty four serum samples from patients with CHB were tested in parallel by DNA microarray and direct sequencing for the mutations within the HBV reverse transcriptase (rt) region, which included rtL180, rtA181, rtM204 and rtN236. Samples with discrepant results were retested by clonal sequencing. Results Complete concordance between DNA microarray and direct sequencing results was observed in 214 out of 224 samples (95. 5% ). The presence of mixed viral populations in the other 10 samples detected by DNA microarray but not by direct sequencing was confirmed by clonal analysis. The DNA microarray could detect minor viral populations which constituted 5.0%-15. 0% of the total viral load. Conclusion DNA microarray is highly consistent with direct sequencing in detecting HBV mutations conferring drug resistance and more sensitive in detecting mixed mutant and wild-type sequences than direct sequencing, which makes it a useful tool for early detection of drug resistance early.

Objective To explore the clinical effect of traditional Chinese medicine and western medicine in treatment of patients with angina pectoris. Methods 120 cases with angina pectoris admitted in the Fourth Hospital of Baotou City from May 2012 to August 2013 were randomly divided into treatment group (n=60)and control group (n=60). All patients were given secondary prevention of coronary heart disease,and besides this, treatment group were added nitrates medications and traditional Chinese medicine treatment,while control group were only given nitrates medications.The treatment course was 14 days. The efficacy of angina pectoris,nitroglycerin loss rate and electrocardiogram efficacy were compared and the safety were evaluated between two groups. Results The efficacy of angina pectoris in treatment group was 90.00%,while control group was 71.67%,the difference was statistically significant(P<0.05 ). ECG efficiency in treatment group was 68.33%,while control group was 48.33%,the difference was statistically significant(P<0.05 ). The reduction of nitroglycerin was 86.67%,while control group was 61.67%,the difference was statistically significant(P<0.05). In addition,there were no adverse reaction in two groups. Conclusion Compared with nitrates medications,combined Chinese and Western medicine in treatment of patients with angina pectoris on basis of secondary prevention of coronary heart disease has better therapeutically effective rate.

OBJECTIVE: To study the effects of Fuzheng Yiliu Granule (FZYLG)-medicated serum on apoptosis of liver cancer cells H22 from mice and its mechanism. METHODS: Liver cancer cells H22 from mice were incubated in culture media containing sera from rabbits medicated with different doses of FZYLG. Flow cytometry was used to examine the cell cycle and analyze the apoptotic rate of the H22 cells. The morphological changes of the H22 cells were observed by transmission electron microscope and the apoptosis related proteins Bcl-2 and Bax were examined by streptavidin-biotin peroxidase complex (SABC) method. RESULTS: FZYLG-medicated serum could influence the cell cycle and stop the proliferation of H22 cells at the G(1)/G(0) phase with apoptotic peak being detected. In culture media with FZYLG-medicated sera, the expression of Bcl-2 decreased while that of Bax increased as compared with that in culture medium with non-medicated serum (P<0.05). CONCLUSION: FZYLG-medicated serum can induce apoptosis of the liver cancer cells H22 by influencing the cell cycle, down-regulating the expression of Bcl-2 and up-regulating the expression of Bax.

Objective To observe the clinical application of extraperitoneal cesarean section(ECS) plus forceps vs transperitoneal cesarean sections(TCS) in repeated cesarean section.Methods 98 multiparous women with scar uterus for elective repeated cesarean sections were recruited retrospectively,47 cases for ECS plus forceps(group A),and 51 cases for TCS(group B).The multiparous women with hyperglycemia not controlled,severe preeclampsia,heart disease,placenta previa,premature rupture of membrane,a history of ＞ 1 cesarean section,myoma and/or ovarian neoplasm were excluded.Results Skin incision to baby delivery time and total operation time of group A were (7.7 ± 2.8) min and (42.8 ± 9.7) min,respectively,which were significantly shorter than (9.3 ± 3.2) min and (47.6 ± 9.4) min of group B,(t =2.700,2.497,P =0.008,0.014).There was significant difference in blood loss volume during the operation and postoperative 2 hours,which was (310.4 ± 106.3) mL,(365.3 ± 142.8) mL respectively(t =2.142,P =0.035).The Visual Analog Scale for pain (VAS pain) was (2.8 ± 1.8) in group A and (4.1 ± 1.9) in group B,respectively (t =3.252,P =0.002).The gastrointestinal function recovery mean time of group A was significantly shorter than that of group B (12.5 h versus 16.0h,t =2.771,P =0.007).And the postoperative febrile morbidity was significantly lower in group A than in group B(8.5％ versus 25.5％ ;x2 =4.918,P =0.033).The patients with chronic pelvic pain followed up after operation was 3 versus 12,and the difference was significant (x2 =5.143,P =0.026).There were no differences in neonatal Apgar score at 1 minute,birth asphyxia and wound healing rates.Conclusion ECS plus forceps can be safely used for repeated cesarean section,with the advantages of less operation time,less bleeding volume,lower postoperative morbidity,and fewer complications than TCS.

Objective To analyze the clinical pathological characteristics of achalasia patients complicated by esophageal cancer.Methods From January 2005 to May 2013,among 658 patients with achalasia,the clinical data,pathological characteristics of tumor and the treatment of those complicated by esophageal cancer were collected and analyzed.At the same time,receiver operating characteristic (ROC) curve analysis was performed to analyze the relationship between the course of achalasia and esophageal cancer.Results Among the 658 patients with achalasia,297(45.1％) cases were male and 361(54.9％) cases were female.A total of 62 cases (9.4％) were lost to follow-up and of 596 cases who completed the follow-up,26 cases (4.4 ％) were complicated with esophageal cancer.Among the 26 patients complicated with esophageal cancer,69.2％ (18/26) were male;the course from achalasia diagnosed to esophageal cancer was (16.5±8.2) years.The patients with a disease duration more than 10 years accounted for 88.5％(23/26),and 80.8％ (21/26) underwent previous balloon dilatation or Heller surgery.The predilection site of esophageal cancer was in the middle esophagus of patients complicated by esophageal cancer (69.2％,18/26),the main type was squamous carcinoma (88.5％,23/26),65.4％(17/26) of the lesions invaded to muscular layer (stage T3 to T4),61.5％(16/26) had the late stage tumor (stage Ⅲ to Ⅳ),and 23.1％(6/26) had distant metastasis.The results of ROC curve analysis showed that when the duration was 10.5 years,the Youden index reached the maximum value (0.71).And 38.5％ (10/26) of patients with esophageal cancer could not be treated with esophageal cancer radical surgery,and their average survival time was (11.4±6.6) months.Conclusion The patients with the duration of achalasia over 10.5 years are required for regular endoscopic examination to improve the prognosis.

Currently,independent clinical medial femoral plate is more needed to apply in more complex C3 distal femoral fractures and knee valgus orthopedic surgery.The doctors always pre-bent the contralateral femoral lateral plate in order to achieve close to the natural shape of the bone.The cold deformation of the plate can change the metallographic structure and the biomechanics,and the position of the screw holes in the plate may also affect the healing of fractures.Compared with traditional manufacturing techniques,3D printing technology as a core technology in third industrial revolution,instead prior manufacture of molds,removing the large amount of material in the manufacturing process and the complex process of forging a final product,it is more suitable for difficult to machine materials,manufacture,inspection shape design,assembly,testing and fast reverse engineering.Therefore,a personalized interior distal femoral plate with 3D printing technology was designed,and the application of the plate,the current situation and prospects of 3D printing technology and other aspects were summarized in this article.
