Influence of degenerative scoliosis on the treatment of lumbar spinal stenosis by MIS-TLIF / 中国骨伤

OBJECTIVE@#To evaluate the effect of degenerative scoliosis on the difficulty and efficacy of minimally invasive transforaminal lumbar interbody fusion(MIS-TLIF) in the treatment of lumbar spinal stenosis.@*METHODS@#From September 2016 to September 2019, 52 patients with lumbar spinal stenosis treated by MIS-TLIF were retrospectively analyzed, including 16 males and 36 females, aged from 42 to 71(63.44±5.96) years old, the course of disease from 1.5 to 6.5 years, with an average of (3.69±1.10) years. All patients had lower extremity root pain or numbness, 41 patients had intermittent claudication. There were 31 cases of L@*RESULTS@#All patients were followed up for 12 to 36 months, with an average of (19.58±5.33) months. The operation time and intraoperative bleeding in stenosis group were better than those in scoliosis group (@*CONCLUSION@#For patients with lumbar spinal stenosis undergoing MIS-TLIF, degenerative scoliosis can lead to prolonged operation time and increased bleeding. However, it has no significant effect on therelief of postoperative symptoms, postoperative complications and the recovery of lumbar function.

Frequencies distribution of GSTT1 and GSTM1 null genotypes in 24 Yunnan populations / 中华医学遗传学杂志

<p><b>OBJECTIVE</b>To investigate the frequencies distribution of GSTT1 and GSTM1 null genotypes in 24 Yunnan populations.</p><p><b>METHODS</b>GSTT1 and GSTM1 genotypes were analyzed by PCR procedure.</p><p><b>RESULTS</b>The range of frequencies for GSTT1 and GSTM1 null genotypes in the populations were 0.188-0.633 and 0.400-0.745, respectively, and in the districts were 0.286-0.583, 0.433-0.745 respectively. There was significant relationship between GSTT1 frequencies and populations.</p><p><b>CONCLUSION</b>The frequencies of GSTT1 and GSTM1 null genotypes in 24 Yunnan populations were different, but they were almost the same in different districts of Yunnan.</p>

The frequency distribution of flavin-containing monooxygenase 3 mutant alleles in 28 populations from Yunnan / 中华医学遗传学杂志

<p><b>OBJECTIVE</b>To study the frequency distribution of flavin-containing monooxygenase 3 (FMO3) mutant alleles in 28 populations originating from 24 ethnic minorities in Yunnan of China.</p><p><b>METHODS</b>FMO3 genotypes were analyzed by polymerase chain reaction-restriction fragment length polymorphism.</p><p><b>RESULTS</b>The average frequencies of FMO3/Stop(148), FMO3/Lys(158) and FMO3/Gly(308) were 0.395(0.174-0.803), 0.208 (0.056-0.414), 0.046(0-0.217), respectively. The frequencies of FMO3/Gly(308) in Blang, Huayaodai, Shuidai, Zhuang, De'ang, Jingpo, Nu and Hui populations were null.</p><p><b>CONCLUSION</b>It was found that the frequencies of FMO3 mutant alleles varied not only in different ethnic groups, but also in different populations that stemmed from the same ethnic group.</p>
