周围神经端侧动脉套接后神经再生的研究

目的研究周围神经端侧动脉套接后神经再生的可能性及其特点. 方法取SD大鼠75只,在股骨中下段切断腓神经,将近断端逆转90度包埋于肌肉中.随机分为5组.A组:将截取的左颈总动脉套接于右侧正常胫神经侧方与腓总神经远端2 mm距离之间,缝合部胫神经外膜不予切除;B组:在胫神经套接部外膜开窗1.0 mm;C组:腓总神经切断14天后再予动脉套接,余同B组;D组:同B组,且于动脉套接部注入神经生长因子(neural growth factor, NGF)1 ml;E组:将腓总神经远端以端侧缝合形式直接缝合于胫神经的一侧,外膜开窗1.0 mm.术后4、8和12周分别行组织学、电镜和神经纤维计数等检查. 结果 4周时C、D及E组周边区域有神经纤维轴突和髓鞘再生,A组则无神经纤维生长; 8周时C、D及E组再生神经纤维较B组多,E组神经纤维较C、D组多,差异有统计学意义(P<0.05); 12周时C、D及E组神经纤维多于B组,差异有统计学意义(P<0.05);C组及D组有较丰富的神经再生,与神经端侧直接吻合的E组差异无统计学意义(P>0.05). 结论神经端侧2 mm距离动脉套接可作为修复周围神经损伤的一种可行方法.

不同采血针对新生儿足跟采血成功率的影响

目的：探讨不同采血针在新生儿疾病筛查采血中的采血效果。方法：采用三种采血针分别对2126例（A组）、1786例（B组）、1471例（C组）新生儿进行足跟采血，比较其采血成功率。结果：A、B、C三组之间差异有统计学意义（P〈0．01）。结论：采用7号一次性注射针头采血（C组）可明显提高采血成功率。     

小儿输尿管开口异位的诊断和治疗(附22例报告)

目的 提高小儿输尿管开口异位的诊治效果。方法 总结22例输尿管开口异位患儿临床资料。男1例，女21例。年龄1个月～12岁，平均4岁。单侧17例，双侧5例。21例女童中，有正常分次排尿伴异常漏尿18例，完全持续性漏尿3例；1例男童有上尿路梗阻及泌尿系感染。异位开口于阴道14例、尿道4例、前庭3例、膀胱颈1例。结果 手术治疗20例，其中肾切除者11例、半肾切除者7例，术后漏尿症状消失，3例合并输尿管残端综合征；1例双输尿管膀胱再植术后仍有尿失禁；1例直肠化膀胱术无漏尿症状。结论 明确诊断，选择合理手术是小儿异位输尿管口治疗成功的关键。     

Recombinant glycoprotein based vaccine for Chandipura virus infection

Chandipura virus (CHPV) has emerged as an important pediatric encephalitis-causing pathogen with very high mortality in India. No specific vaccine or treatment is available till date. We attempted to prepare a candidate vaccine employing recombinant CHPV Glycoprotein (rGp). The Glycoprotein gene (G-gene) of CHPV was expressed using Baculovirus expression system. The rGp was purified by HPLC and used for mice immunization, 3 doses, and 4 weeks apart. One microgram rGp was found to be optimum. Sero-conversion was observed as early as 2nd week by detecting anti-CHPV IgG antibodies. Antibody titres were immunogen-concentration dependent. Intracerebral challenge of the immunized mice with 100 LD₅₀ of the homologous strain demonstrated 90% protection. In in vitro neutralization, antibodies from the immunized mice were able to neutralize heterologous viruses. There was 60% T cell proliferation observed against rGp in immunized mice. The study shows that rGp induces both arms of immune response and represents an ideal vaccine candidate for further evaluations.     

Extacorporeal shock wave therapy unsuccessful for chronic medial epicondylitis

Medial epicondylitis is a chronic noninflammatory condition resulting from mechanical injury. Despite many treatment options, including rest, medications, physiotherapy and operative interventions, the results are too often poor; thus new treatment options are sought. We treated 4 men with chronic epicondylitis (5 affected joints) with extracorporeal shock wave therapy after failed attempts of other treatments. The patients’ complaints were graded with the Nirschl scoring system prior to and six months after therapy. The treatment consisted of three sessions, at 20-day intervals, of 3000 pulses of ultrasonic shock waves from a Piezolith 3000 unit (energy dosage was gradually increased to reach step 10 equaling 0.9 mJ/mm²). At the 6-month follow-up, no patient was pain free. Three cases had slightly lower Nirschl scores than prior to the procedure but the patients rated this difference as insignificant; two cases were unchanged. No complications were observed but all patients rated the procedure as very unpleasant. The well recognized biologic effects of ultrasonographic waves (heat generation, oscillations, cavitation, etc.) that result in functional and structural changes of cellular membranes with sonochemical reactions (acceleration of normal metabolism, oxygenation and reduction in water solutions, polymer degradation, etc.), even if present in our cases, did not result in a noticeable decrease of symptoms, even though we used high energy and more impulses per session. Significant variations in methodology make inconclusive the results of numerous reports on the use of extracorporeal shock waves in epicondylar degenerative problems, although ineffectiveness of such therapy is the conclusion of a review by Haake and colleagues.     

基于非复制系统强化实现混沌同步的研究

研究了基于非复制系统强化实现混沌同步的方法。通过选取非复制系统中合适的控制参数，可以实现混沌系统的同步。并且当复制系统不能同步时，用非复制响应系统同样可以实现混沌同步，或者加速实现混沌系统的同步化。通过对Chua混沌电路和混沌的Lorenz系统的同步设计和数值仿真，验证了其有效性。
