Objective To observe the clinical effect of Yangyin Tongluo Pills combined with acupuncture for the treatment of cerebral infarction sequela. Methods One hundred patients with cerebral infarction sequela were evenly randomized into treatment group and control group. The control group was given acupuncture therapy combined with oral use of clopidogrel, and the treatment group was given acupuncture therapy combined with oral use of Yangyin Tongluo Pills (mainly composed of Fructus Lycii, Flos Chrysanthemi, Radix Rehmanniae, Cortex Moutan, Radix Salviae Miltiorrhizae, Flos Carthami, Semen Persicae, Pheretima, Rhizoma Gastrodiae, Ramulus Uncariae cum Uncis, Spica Prunellae, Radix Glehniae, Radix Ophiopogonis, Fructus Schisandrae Chinensis, Radix Pseudostellariae) . One month constituted a treatment course, and the treatment covered 2 courses. After treatment, the therapeutic effect of the two groups was evaluated, and the changes of National Institute of Health Stroke Scale ( NIHSS) scores and Barthel Index Scale for activities of daily living ( ADL) , and hemorrheology indexes were observed before and after treatment. Results (1) After treatment for 2 courses, NIHSS scores were decreased, ADL scores were increased in the two groups (P<0.01 compared with those before treatment) , and the improvement of the treatment group was superior to that of the control group ( P<0.01) . ( 2) After treatment, hemorrheology indexes were much improved in the treatment group ( P<0 . 05 or P<0 . 01 ) , but remained unchanged in the control group ( P>0.05) . The treatment group had better effect on improving hemorrheology indexes than the control group (P<0.05) . (3) The total effective rate of the treatment group was 90.00% and that of the control group was 64.00%, the overall therapeutic effect of the treatment group being superior to that of the control group (P<0.05) . Conclusion Yangyin Tongluo Pills combined with acupuncture are effective for the treatment of cerebral infarction sequela, and the effect is superior to that of acupuncture combined with clopidogrel.

As in the building of deep buried long tunnels, there are complicated conditions such as great deformation, high stress, multi-variables, high non-linearity and so on, the algorithm for structure optimization and its application in tunnel engineering are still in the starting stage. Along with the rapid development of highways across the country, It has become a very urgent task to be tackled to carry out the optimization design of the structure of the section of the tunnel to lessen excavation workload and to reinforce the support. Artificial intelligence demonstrates an extremely strong capability of identifying, expressing and disposing such kind of multiple variables and complicated non- linear relations. In this paper, a comprehensive consideration of the strategy of the selection and updating of the concentration and adaptability of the immune algorithm is made to replace the selection mode in the original genetic algorithm which depends simply on the adaptability value. Such an algorithm has the advantages of both the immune algorithm and the genetic algorithm, thus serving the purpose of not only enhancing the individual adaptability but maintaining the individual diversity as well. By use of the identifying function of the antigen memory, the global search capability of the immune genetic algorithm is raised, thereby avoiding the occurrence of the premature phenomenon. By optimizing the structure of the section of the Huayuan tunnel, the current excavation area and support design are adjusted. A conclusion with applicable value is arrived at. At a higher computational speed and a higher efficiency, the current method is verified to have advantages in the optimization computation of the tunnel project. This also suggests that the application of the immune genetic algorithm has a practical significance to the stability assessment and informationlzation design of the wall rock of the tunnel.

BACKGROUND:Navigation assisted minimal y invasive posterior lumbar interbody fusion and pedicle screw fixation can precisely real-time guide a variety of operation under minimal y invasive sleeve, and implant the pedicle screws and interbody fusion cage and other implants safely and accurately, thus can determine the decompression parts. Minimal y invasive transforaminal lumbar interbody fusion is the typical approach in recent years for the successful application of minimal y invasive spine surgery techniques with the advantages of smal incision, less bleeding, slight tissue damage and faster recovery. OBJECTIVE:To evaluate the short-term effect of minimal y invasive transforaminal lumbar interbody fusion with real-time three-dimensional navigation system and open posterior transforaminal lumbar interbody fusion. METHODS:Forty cases with single-level lumbar disc herniation were retrospectively analyzed. The patients were treated with minimal y invasive transforaminal lumbar interbody fusion with real-time three-dimensional navigation system (20 cases) and open posterior transforaminal lumbar interbody fusion (20 cases) respectively for the comparative analysis. The fusion duration, intraoperative blood loss, postoperative drainage volume, the length of postoperative hospital stay and the length of hospital stay were compared between two groups. The wound pain and function were evaluated after treatment with visual analogue scale score and Japanese Orthopaedic Association score. RESULTS AND CONCLUSION:Al patients were fol owed-up for 7.7 months. The operative duration in the minimal y invasive transforaminal lumbar interbody fusion group was longer than that in the open posterior transforaminal lumbar interbody fusion group, and the difference was significant (P<0.01);the length of hospital stay and length of postoperative hospital stay of the minimal y invasive transforaminal lumbar interbody fusion group were shorter than the open posterior transforaminal lumbar interbody fusion group, and the differences were significant (P<0.01);the intraoperative blood loss of the minimal y invasive transforaminal lumbar interbody fusion group was less than the open posterior transforaminal lumbar interbody fusion group, and the difference was significant (P<0.05);the postoperative drainage volume of the minimal y invasive transforaminal lumbar interbody fusion group was less than the open posterior transforaminal lumbar interbody fusion group, and the difference was significant (P<0.01). The visual analogue scale score was significantly decreased and the Japanese Orthopaedic Association score was significantly increased in the minimal y invasive transforaminal lumbar interbody fusion group at 3 days after internal fixation compared with open posterior transforaminal lumbar interbody fusion group (P<0.01), but there were no significant differences in the visual analogue scale score and Japanese Orthopaedic Association score between the two groups before operation and 6 months after operation (P>0.05).The results indicate that minimal y invasive transforaminal lumbar interbody fusion with real-time three-dimensional navigation system is an effective method for lumbar disc herniation with the advantages of less intraoperative blood loss, less postoperative drainage volume, smal trauma, short hospital stay and short-term efficacy.

AIM: To investigate the effects of low-dose paclitaxel on the morphology of bladder after partial bladder outlet obstruction ( BOO) in rats.METHODS:Healthy female Sprague-Dawley rats ( n=30) were randomly di-vided into sham operation group, BOO group and low-dose paclitaxel group.The rats in BOO group and low-dose paclitaxel group received operation to establish an obstruction model, while the rats in sham group underwent sham operation.After operation, the rats in low-dose paclitaxel group received intraperitoneal injection of paclitaxel at a dose of 0.3 mg/kg twice a week for 4 weeks.At the same time, the animals in sham group and BOO group received the same volume of saline by in-traperitoneal injection.Four weeks after operation, each rat was sedated and the bladder was weighted.Histological chan-ges of the bladder were observed by HE staining.Collagen deposition in the bladder tissue was observed by Masson stai-ning, and the fibrosis area was measured.The ultrastructure of the detrusor was studied by transmission electron microsco-py.RESULTS:Compared with sham operation group, a significant increase in bladder weight (0.376 g ±0.052 g vs 0.112 g ±0.014 g, P<0.05), the muscle hypertrophy, and a decrease in the percentage of collagen area [collagen/(col-lagen+muscle), 29.66%±2.69%vs 38.94%±3.67%, P<0.05] was observed in BOO group.Under electron micro-scope, intracellular connection had more gap junction and desmosomes than intermediate junction.The cell gap widened with a large amount of collagen fiber.Compared with BOO group, low-dose paclitaxel group decreased bladder weight (0.215 g ±0.025 g vs 0.376 g ±0.052 g, P<0.05) and improved the muscle hypertrophy.The percentage of the colla-gen area was also decreased (19.94%±1.90% vs 29.66%±2.69%, P<0.05).The detrusor microstructure showed that the intermediate junction was characterized by a predominance among the intracellular connections, and the intercellu-lar space contained less collagen fibers in low-dose paclitaxel group.CONCLUSION:Low-dose paclitaxel may ameliorate the morphological damage of the bladder and recover bladder function in the rats with BOO by slowing down the process of bladder fibrosis.

Objective To investigate the relationships between aspirin resistance (AR) and laboratory indexes and different types of traditional Chinese Medicine(TCM)syndrome in patients with acute cerebral infarction. Methods Two hundred and eight different types of TCM syndromes of patients with acute cerebral infarction admitted from January 2012 to November 2013 in the Neurology Department of Shanghai Seventh People's Hospital were divided into AR group and aspirin sensitive(AS)group according to the rate of AR. Simultaneously,28 healthy volunteers in the same period were assigned in a healthy control group. The changes of red blood cell volume distribution width coefficient of variation(RDW-CV),platelet count(PLT)and homocysteine(Hcy)levels were observed in the three groups. The correlation between different types of TCM syndromes and AR,PLT,RDW-CV,and Hcy was analyzed by non-conditional logistic regression. Results The total incidence of AR was 29.32%(61/208)in 208 patients with acute cerebral infarction. There were 165 cases with Qi deficiency and blood stasis syndrome,the incidence of AR being 26.06%(43/165);32 cases with wind phlegm obstructing channel syndrome,the incidence of AR, 43.75%(14/32);11 cases with liver yang hyperactivity syndrome,the incidence of AR,36.36%(4/11);in the comparisons,the incidence rates of AR among the above types of syndromes had no statistical significant differences (P>0.05). Compared with the healthy control group,the levels of PLT,RDW-CV,Hcy in AR group and AS group of various types of TCM syndrome were increased,the PLT and RDW-CV levels in patients with Qi deficiency and blood stasis syndrome in AR group were more significantly elevated in the comparisons between AR and AS groups, there were statistical significant differences〔PLT (×109/L):212.16±66.48 vs. 187.54±56.85, RDW-CV:(14.34±3.16)% vs.(13.20±2.16)%,both P<0.05〕;the level of Hcy in patients with wind phlegm obstructing channel syndrome in AR group was increased more significantly than that in AS group,the difference between the two groups being statistically significant(μmol/L:27.29±18.64 vs. 21.36±14.61,P<0.05). Logistic regression analysis showed,increased PLT〔odds ratio(OR)=1.007 2,95%confidence interval(CI):1.001 2-1.013 2,P=0.018 5〕and RDW-CV〔OR=1.165 4,95%CI:1.007 9-1.347 4,P=0.038 8)was independence risk factor of AS development. Conclusion The elevation of RDW-CV,PLT,Hcy in level reflects the index of AR production, especially in patients with acute cerebral infarction accompanied by Qi deficiency and blood stasis syndrome and wind phlegm obstructing channel syndrome.
