This study was aimed to discuss the distribution and protein expression level ofμ-opioid receptor (MOR) in hippocampus of premenstrual syndrome (PMS) liver-qi stagnation rat model, in order to initially reveal the action mechanism of PMS liver-qi stagnation and intervention effect ofShu-Yu (SY) capsule. Chronic restraint stress method was used to copy PMS liver-qi stagnation rat model.SY capsule ofTiao-Gan prescription was given as intervention. Immunofluorescence (IF) and western blot (WB) technique were used to detect MOR in hippocampal CA1 and CA3 brain area of rats from each group. The results showed that compared with the normal group, the hippocampus MOR distribution arrangement was messy with increased protein concentration in the model group (P< 0.01). After drug intervention, the MOR protein level returned to normal level. It was concluded that the pathogenesis of PMS liver-qi stagnation may be associated with high expression of MOR in hippocampus CA1 and CA3 region of rats. SY capsule can effectively correct and restore it to nearly normal level. It may be one of the central mechanisms in SY capsule treatment of PMS liver-qi stagnation.

The X-ray computed tomography (CT) appearance of 4 cases with pulmonary cryptococcosis (PC) diagnosed by pathological examination in our hospital was retrospectively analyzed. The appearances of PC on CT were various: solitary lesion in 1 case, multiple lesions in single lobe in 2, and multiple lesions in multiple lobes in 1. There were total 52 lesions in 4 cases; the diameter of nodules or masses was 3 - 75 mm. Cavitations were found in 1 case; lesions appeared obviously enhanced and one lesion showed central necrosis. Two cases underwent pulmonary lobectomy; and 2 cases received core cutting needle biopsies, after antifungal therapy for 3 months to 1 year the lesions showed being absorbed. In summary, the CT appearance of PC is non-specific with various modes and forms. PC should be considered when multiple nodules or masses scattered in subpleural zone, accompanied with ground-glass opacity and obviously enhanced. The examination of pathogen and pathology at the beginning is crucial for improving diagnostic accuracy.

Objective To explore the association between clinical pathological characteristics and the expressions of epidermal growth factor receptor (EGFR) and protein kinase B (AKT) in gastric carcinomas.Methods The expressions of EGFR and AKT were measured with immunohistochemical method in the cancer tissues and cancer-adjacent normal tissues from 153 cases of patients with gastric cancer.The association between clinical pathological characteristics and their expressions were analyzed.Results The expressions of AKT and EGFR in gastric cancer tissues had no relationship with gender,age,pathological type,and the degree of differentiation (P ＞ 0.05).A positive correlation was existed between the EGFR and TNM stages (x2 =5.43,P ＜0.05).The AKT was positively related to the size,T stage,and TNM stage of the tumor,respectively (x2 =4.73,4.95,5.32,P ＜0.05 orP ＜0.01).The levels of AKT (x2=4.83,4.75,P ＜0.05) and EGFR(x2 =4.67,4.58,P ＜0.05) in the gastric cancer tissues with lymph node and/or distant metastasis were significantly higher than the gastric cancer tissues without metastasis,respectively.Conclusions The over-expressions of AKT and EGFR would benefit the diagnosis and stages of a gastric cancer and the determination of its metastasis.
