A 30-year-old woman with longstanding dizziness was found to have a severe postural fall in blood pressure and a reduced skin axon-reflex flare response. Autonomic tests indicated selective impairment of adrenergic sympathetic function. Plasma noradrenaline, adrenaline, dopamine, and dopamine beta hydroxylase were undetectable. Skin biopsy specimens showed loss of tyrosine hydroxylase and neuropeptide Y (markers of adrenergic sympathetic fibres) and of substance P and calcitonin gene-related peptide (sensory neuropeptides). A sural nerve biopsy specimen showed severe depletion of unmyelinated fibres. The constellation of losses were compatible with nerve growth factor (NGF) deprivation, which was confirmed on assay. This new syndrome may be explained by loss of trophic action of NGF.

Objective To observe the changes of Chinese medicine (CM) symptoms, the distri- bution characteristics of CM syndromes, and related neuroendocrine levels in premenstrual dysphoric disorder (PMDD) patients. Methods Totally 3 541 female outpatients (18 -45 years old) were inter- viewed by clinical epidemiological questionnaire. According to PMDD diagnostic criteria in DSM-IV , PMDD patients' CM syndromes were identified. Their scores of main symptoms and CM symptoms of common CM syndromes were compared. Contents of 8 neuroendocrine indicators in serum were detected [5- hydroxytryptamine (5-HT) , adrenocorticotropic hormore (ACTH) , angiotensin-II (Ang-II ) , glucocorti- coid (GC), homocysteine (Hcy), melatonin (MLT), nitrogen monoxide (NO), neuropeptide Y (NPY)]. Results Totally 258 PMDD were detected in 3 541 female outpatients (18 -45 years old). The main syn- drome and common syndromes of PMDD patients were reversed invasion of Gan qi syndrome [40.3% (104/258)] and stagnation of Gan qi syndrome [34. 9% (90/258) ], followed by Gan stagnation Pi deficiency syndrome [7.8%(20/258)], Gan stagnation blood stasis syndrome [7.4% (19/258)], Gan stagnation induced fire hyperactivity syndrome [ 6.2% ( 16258 )], Gan stagnation Shen deficiency syndrome [3.1%(8/258)], and Pi-Shen yang deficiency syndrome [0.4%(1258)]. Compared with reversed invasion of Gan qi syndrome, emotional depression and low spirits were main symptoms of stagnation of Gan qi syndrome. Scores for the two symptoms increased (P <0.05). Compared with stagnation of Gan qi syn- drome, irritability, upset, abdominal distension, anxiety, headache, dizziness, insomnia, head distension, bitter mouth, unclear vision were main symptoms of reversed invasion of Gan qi syndrome. Scores for the 10 symptoms increased (P <0.05). Compared with stagnation of Gan qi syndrome, the Hcy level in serum obviously decreased in reversed invasion of Gan qi syndrome (P <0.05). There was no statistical difference in the rest indices (P >0. 05). Conclusions PMDD is closely related to Gan failing to maintain normal flow of qi. Reversed invasion of Gan qi syndrome and stagnation of Gan qi syndrome have different scientif- ic connotations and biological bases. So regulating Gan should be considered as the first choice.
