本文介绍郭志强教授运用崇阳理论治疗反复胚胎移植着床失败的经验.郭老认为妇人体质"阴常不足,阳亦常虚",形成"阴阳相济,阴基阳主"的崇阳理论.认为反复胚胎移植着床失败的主要病机为肾阳不足,胞宫寒冷,不能摄精成孕,提出治疗应从阳气着手,并秉持着求子先调经的原则,在胚胎移植前采用中药序贯疗法调经促孕,胚胎移植后予两固汤补肾温阳,顾护阳气,促进着床.     

Muscle-specific knockout of PKC-lambda impairs glucose transport and induces metabolic and diabetic syndromes

Obesity, the metabolic syndrome, and type 2 diabetes mellitus (T2DM) are major global health problems. Insulin resistance is frequently present in these disorders, but the causes and effects of such resistance are unknown. Here, we generated mice with muscle-specific knockout of the major murine atypical PKC (aPKC), PKC-lambda, a postulated mediator for insulin-stimulated glucose transport. Glucose transport and translocation of glucose transporter 4 (GLUT4) to the plasma membrane were diminished in muscles of both homozygous and heterozygous PKC-lambda knockout mice and were accompanied by systemic insulin resistance; impaired glucose tolerance or diabetes; islet beta cell hyperplasia; abdominal adiposity; hepatosteatosis; elevated serum triglycerides, FFAs, and LDL-cholesterol; and diminished HDL-cholesterol. In contrast to the defective activation of muscle aPKC, insulin signaling and actions were intact in muscle, liver, and adipocytes. These findings demonstrate the importance of aPKC in insulin-stimulated glucose transport in muscles of intact mice and show that insulin resistance and resultant hyperinsulinemia owing to a specific defect in muscle aPKC is sufficient to induce abdominal obesity and other lipid abnormalities of the metabolic syndrome and T2DM. These findings are particularly relevant because humans who have obesity, impaired glucose tolerance, and T2DM reportedly have defective activation and/or diminished levels of muscle aPKC.     

Evaluation of the vascular architecture of hepatocellular carcinoma by micro flow imaging: pathologic correlation.

OBJECTIVE: The purpose of this study was to evaluate micro flow imaging (MFI) in depicting the vascular architecture of hepatocellular carcinoma (HCC) and the correlation between pathologic differentiation and the intratumoral vascular architecture pattern. METHODS: Micro flow imaging and contrast harmonic imaging (CHI) were performed in 37 patients with HCC. A sulfur hexafluoride-filled microbubble contrast agent was used. The enhancement level and intratumoral vessels were evaluated on CHI. The vascular architecture of each tumor was evaluated on MFI. Pathologic differentiation of the tumors was classified according to the Edmondson grading system. RESULTS: All 37 HCCs showed hyperenhancement in the arterial phase and hypoenhancement in the portal and late phases on CHI. Intratumoral vessels in the arterial phase were visualized in 20 (54.1%) HCCs. On MFI, the vascular architecture in all lesions was clearly delineated and categorized into 3 patterns: cotton, shrubbery, and deadwood, identified in 12 (32.4%), 22 (59.5%), and 3 (8.1%) of the tumors evaluated, respectively. A chi(2) test showed that pathologic differentiation significantly correlated to the vascular pattern (P = .006). Three (75%) of 4 Edmondson grade I HCCs showed the cotton pattern; 18 (75.0%) of 24 Edmondson grade II HCCs showed the shrubbery pattern; and the deadwood pattern was shown only in Edmondson grade III and IV HCCs. CONCLUSIONS: The MFI technique is more effective in depicting the intratumoral vascular architecture. The vascular architecture pattern correlates with pathologic differentiation of HCC.

Cerebral microbleeds in patients with Parkinson’s disease

Cerebral microbleeds (CMBs) are known to be associated with cognitive impairments in the elderly and in patients with various diseases; however, the nature of this association has not yet been evaluated in Parkinson’s disease (PD). In the present study, we analyzed the incidence of CMBs in PD according to cognitive status, and the impact of CMBs on cognitive performance was also evaluated. The CMBs in PD with dementia (n = 36), mild cognitive impairment (MCI, n = 46), or cognitively normal (n = 41) were analyzed using conventional T2*-weighted gradient-recalled echo images. Additionally, the relationship between the presence of CMBs and cognitive performance on individual tests of cognitive subdomains was analyzed using a detailed neuropsychological test. CMBs occurred more frequently in PD patients with dementia (36.1 %) compared to those with MCI (15.2 %), those who are cognitively normal (14.6 %), and normal controls (12.2 %, p = 0.025). However, the significant association of CMBs with PD dementia disappeared after adjusting white matter hyperintensities (WMHs) as a covariate. The frequencies of deep, lobar, and infratentorial CMBs did not differ among the four groups. After adjusting for age, sex, years of education, and WMHs, PD patients with CMBs had poorer performance in attention domain compared with those without CMBs (34.9 vs 42.6, p = 0.018). The present data demonstrate that even though CMBs were inseparably associated with the presence of WMHs, CMBs occur more commonly in PD patients with dementia than in those without dementia. Additionally, the burden of CMBs may contribute to further cognitive impairment in PD.     

Nesfatin-1 Decreases Excitability of Dopaminergic Neurons in the Substantia Nigra

Nesfatin-1, a newly discovered satiety molecule which reduces feeding behavior, has been recognized as a unique regulatory neuropeptide with its multiple roles, both central and peripheral. However, whether it had neuronal modulation effect on dopaminergic neurons is largely unknown. In the present study, using whole-cell patch clamp under current-clamp mode, we investigate the effects of nesfatin-1 on the electrical activity of rat nigral dopaminergic neurons. Nesfatin-1 could produce a resting membrane potential hyperpolarization on the majority of dopaminergic neurons tested. The spike frequency decreased by 23.13?±?5.93 and 43.20?±?5.56 % in 5-nM and 10-nM nesfatin-1 groups, respectively. These effects persisted in the presence of ionotropic glutamate and GABA receptor antagonists. Our study suggests that nesfatin-1 postsynaptically inhibits the electrical activity of nigral dopaminergic neurons.
