Objective To investigate the effect of through frontal keyhole approach neuroendoscopic surgery of basal ganglia hemorrhage on nerve conduction tract and prognosis.Methods 56 patients with hypertensive basal ganglia hemorrhage treated in our department from October 2017 to October 2023 were selected and divided into observation group and control group.Among them,28 patients in the control group underwent microscopic surgery through temporal cortex approach,while 28 patients in the observation group underwent endoscopic surgery through frontal keyhole approach.Fractional anisotropy and activities of daily living were compared between the two groups after operation.Results The proportion of FA Ⅰ grade in observation group was 88.9％and 70.0％in GCS Ⅰ grade and GCS Ⅱgrade patients,respectively,while in control group it was 75.0％and 41.7％.The proportion of ADL Ⅰand Ⅱ grade in observation group was 94.4％and 70.0％in GCS Ⅰ grade and GCS Ⅱ grade patients,respectively,whereas in control group it was 81.3％and 41.7％.The integrity of the corticospinal tract and activities of daily living in observation group were better than those in control group,with statistical significance(P＜0.05).Conclusion The surgery of hypertensive basal ganglia hemorrhage with neuroendoscopy through frontal keyhole approach has little influence on nerve conduction tract and the prognosis was better than traditional microscopic surgery through temporal cortex approach.

Objective:To analyze the risk factors of postinflammatory hyperpigmentation (PIH) after laser in the treatment of acquired bilateral nevus of Ota-like macules (ABNOM).Methods:A retrospective study was conducted to follow up 120 patients with acquired bilateral nevus of Ota-like macules in the Department of Laser and Physiotherapy, Guangzhou Institute of Dermatology between January 2011 and December 2018, which accepted 1064-nm Q-switched neodymium: yttrium-aluminum-garnet laser treatment. The difference was analyzed between different age, sex, clinical classification, Fitzpatrick skin classification, ABNOM with melasma and postinflammatory pigmentation after laser treatment. Logistic regression was used to analyze the risk factors of postinflammatory hyperpigmentation after 1064-nm Q-switched neodymium: yttrium-aluminum-garnet laser treatment of acquired bilateral nevus of Ota-like macules.Results:Fifty-three ABNOM patients (44.17%) developed PIH after laser treatment. Univariate analysis showed that age, clinical classification, Fitzpatrick skin classification and the patients with both ABNOM and melasma all affected the occurrence of PIH after laser in the treatment of ABNOM, and the difference was statistically significant ( P<0.01). Logistic regression showed that older age, more severe clinical classification and the presence of ABNOM with melasma were the risk factors of PIH after treatment of ABNOM. Conclusions:ABNOM patients should be treated as early as possible. The risk of inducing PIH is great after laser treatment in patients with more severe clinical classification and patients with both ABNOM and melasma.

Objective To investigate the genetic relationships of Astragalus membranaceus and Codonopsis pilosula from the different cultivars (varieties). Methods Twenty-five samples of A. membranaceus and seventeen samples of C. Pilosula were amplified by ISSR-PCR. Genetic diversity and genetic distance were analyzed by Popgen32. UPGMA dendrogram relationship was clustered by NTSYS. Results Totally 62 and 100 loci were detected respectively from A. membranaceus and C. pilosula. All percentages of polymorphic loci (PPL) were 100%. Shannon’s information indexes (I) were 0.537 6 and 0.472 7. Nei’s genetic diversity indexes (H) were 0.361 3 and 0.307 4. A. membranaceus was divided into two groups in genetic distance 0.59, and C. pilosula was alike in 0.50. Conclusion Different cultivars (varieties) of A. membranaceus and C. pilosula had rich genetic diversities among species, and had large genetic differences.
