耳穴贴压治脑震荡后遗症20例

脑震荡患者在恢复期或伤后3个月内，头部仍有胀痛，搏动性疼痛，或有紧缩感，脑力劳动后多加重，常伴有头昏、脑晕、耳鸣、记忆力减退、失眠及植物神经功能紊乱等症状，为脑震荡后遗症。祖国医学认为，头为清阳之会，五脏精华之血、六腑清阳之气均上注于头。若头部受外伤则阻滞气血之运行，脑失其养或清阳遏阻则可出现上述症状。笔者近两年来用王不留行籽耳穴贴压治疗脑震荡后遗症20例，疗效满意，现报告如下。

Expression of zinc-positive cells and terminals in fetal neocortical homografts to adult rat depends on lesion type and rearing conditions

Zinc-positive neurons and terminals, known to be associated with the glutamatergic projections in the brain, can be demonstrated by the histochemical Timm method and later modifications thereof. The adult rat neocortex contain a uniform lamination of zinc-positive cells with specific projections to, e.g., the striatum. We have previously reported that fetal neocortical grafts implanted in the adult rat neocortex combined with rearing in an enriched environment can improve behavioral functions and reduce the secondary atrophy of thalamus after cortex infarction in adult rats. In order to examine whether the expression of zinc positivity is ontogenetically inherent to neocortical neurons we grafted fetal neocortical tissue to aspiration or ischemic lesions of the frontoparietal neocortex of adult rats, followed by histochemical visualization of the vesicular zinc pool by selenite or sulfide. One further aim of the study was to elucidate to what extent the distribution of zinc-containing neurons and terminals in the grafts depended on rearing under different environmental conditions. The foremost finding of the present study was that the overall density of zinc-containing terminals in fetal cortical transplants placed in brain infarcts of adult spontaneously hypertensive rats is higher when the rats are reared in an enriched environment. Moreover, the presence and expression of zinc-positive neurons and terminals do not seem to be ontogenetically inherent to the cortical neurons as the fetal neocortical grafts placed in aspiration lesions contained no zinc-selenide-positive neurons and few or no zinc-selenide-positive terminals. The presence or expression of zinc-positive cells may thus be induced by ingrowth of fibers and terminals from the host brain as transplants placed in the ischemic lesions expressed both zinc-positive neurons and terminals.     

鼻腔鼻窦鳞状细胞癌中细胞质凋亡抑制蛋白2和半胱氨酸蛋白水解酶4的表达

OBJECTIVE: To examine the expression of apoptosis-related genes c-IAP2 and caspase-4 in sinonasal squamous carcinoma. To investigate the role and mechanism of the two apoptosis-related genes in nasal cavity and sinus squamons carcinoma. METHODS: Forty-one pathologically confirmed specimens of nasal cavity and sinus squamons carcinoma were subjected for immunohistochemical staining to analyze the expression of c-IAP2 and caspase-4, in addition 10 normal nasal mucosa were used as control. RESULTS: The positive rate of c-IAP2 in sinonasal squamons carcinoma was 87.8%, among which 14 cases were strongly stained(+ + +), 15 cases were stained(+ +), 7 cases were stained (+), only 5 cases were negative. In 10 normal control tissues, no case was stained(+ + +), 2 cases were stained (+ +), 3 cases were stained(+), the other 5 cases were negative. Higher level expression of c-IAP2 protein was detected more often in squamons carcinoma specimens than that in normal nasal mucosa. There was statistically significant difference between the two groups for the staining(P < 0.05). The expression of c-IAP2 was not correlated with clinical staging (P > 0.05), but there were positive correlation with clinical prognosis (P < 0.01) and pathological classification (P < 0.01); The positive rate of caspase-4 in nasal cavity and sinus squamons carcinoma was 58.5%, among which 4 cases were strongly stained (+ + +), 7 cases were stained (+ +), 13 case was stained(+), 17 cases were negative. The expression of caspase-4 protein was more deletion in squamons carcinoma specimens than that in control group, there was statistically significant difference between the two groups for the staining (P < 0.05). The expression of caspase-4 protein was negatively correlated with clinical prognosis (P < 0.01) and pathological classification ( P < 0.01), not correlated with clinical staging(P > 0.05). The expression of c-IAP2 was negativelly correlated with the experssion of caspase-4. CONCLUSIONS: The results indicates that in sinonasal squamous carcinoma, c-IAP2 is activated, while caspase-4 is restrained, the signal transduction pathway of apoptosis is arrested, leading to surviving of tumor cells, this maybe directly associated with the development of sinonasal squamons carcinoma, and with the failure of tumor trentment.

眼灌注压对人视乳头微循环的影响

目的 了解眼外负压吸引诱导的眼灌注压改变的条件下，正常人、原发性开角性青光眼(POAG)患者和正常眼压性青光眼患者(NTG)的视乳头微循环的变化，探讨视乳头局部自身调节的幅度。方法正常人8例，POAG患者10例和NTG患者7例，采用眼外负压杯吸引诱导眼压升高，负压增加的幅度为30s50mmHg，同时测量眼压。采用HRF测量视乳头处血流量。将基础状态下视乳头血流值作为基础值，当眼压升高到30mmHg和40mmHg时，分别测量这两点视乳头微循环的血流值，在40mmHg后解除负压吸引，测量负压吸引解除后1min、5min时视乳头微循环的血流值。结果 三组视乳头的基础血流量无明显差异。当眼压升高到30mmHg时，正常组的血流量仍维持稳定，但POAG组和NTG组明显下降，POAG组下降幅度超过25％，NTG组下降幅度超过45％。当眼压升高到40mmHg，正常组视乳头血流量也出现明显下降，其中0NHF下降约30％，POAG组和NTG组下降更明显，POAG组下降幅度超过50％，NTG组下降幅度超过65％。在解除负压吸引后1min，正常组血流量增加的幅度约为31％，POAG组增加约19％，NTG组无明显增加。在负压解除后5min，三组视乳头血流基本恢复到基础状态。结论 正常组视乳头微循环有一定范围的自身调节幅度，可以耐受眼灌注压一定程度的改变，POAG组和NTG组自身调节能力均有不同程度的损害。
