This study was aimed to observe effects of traditional Chinese medicine (TCM) treatment from lung on mRNA expressions of iNOS in lung tissues of rats with ulcerative colitis (UC). A total of 52 rats were used to estab-lish the UC rat model by using rabbit intestinal mucosal tissue allergenic model and TNBS-ethanol model (with the model success rate of 78%). Eight rats, which were randomly selected from 40 successfully modeled rats and the normal group, were used as the model group and the normal group before intervention (time point of week zero). The rest 32 successfully modeled rats were randomly divided into the model group, the western medicine (salazosulfapyri-dine) group, treatment from lung (Huang-Qi Jie-Geng, HQJG decoction) group, and treatment from intestine (Huang-Qi Huang-Lian, HQHL decoction) group, with 8 rats in each group. Another 8 normal rats were used as the control group. The intervention was given for 4 weeks. And the mRNA expression of iNOS was detected in week ze-ro, and four weeks after the treatment using real time-PCR. The results showed that in the acute phase of week zero, the mRNA level of iNOS in lung tissues of model group was significantly increased compared with that in normal group (P < 0.05); after 4-week treatment, compared with the normal group, the mRNA level of iNOS in the model group was significantly increased (P< 0.05). Compared with the model group, the mRNA level of iNOS in the treat-ment from lung group was significantly decreased (P < 0.01). It was concluded that NO which was catalyzed and synthesized by iNOS played an important role in pulmonary diseases. It can cause airway inflammation, edema, lung injury, and etc. Treatment from lung can alleviate the lung injury by inhibiting abnormal activation of iNOS.

Objective To investigate protective effects and mechanism of folic acid on brain neural cells in preeclampsia rat model.Methods Adult pregnant Wistar rats were randonly divided into 4 groups (n = 10 in each group).Rats in model group were injected intraperitoneally with homocysteine (Hcy,200 mg · kg-1 · d-1) daily and were injected subcutaneously every other day with monosodium glutamate (MSG,1 g · kg-1 · 48 h-1) from the 10th day of pregnancy to establish the model of preeclampsia. Lowdose folic acid (low dose group 10 ng · kg-1· d-1) and high-dose folic acid (high dose group 20 mg · kg-1 · d-1 ) were given intragastric administration with folic acid tablets dissolved in saline daily at the same time of establishing model.Rats in control group were injected or intragastric administration with the same dose of saline as above up to the 20th day of pregnancy.Brain tissue was fixed on the 20th day of pregnancy, so was that plasma folic acid was measured with automatic electro-chemiluminescence.Rats' immunohistochemical staining.bcl-2 mRNA and protein expression changes were observed by using reverse transcription(RT) -PCR and western blot.Results ( 1 ) Plasma folate concentrations were ( 39.5 ± 3.4 )nmol/L in low dose group and (40.1 ±5.4) nmol/L in high dose group, which were all significantly higher than (26.9 ± 6.7 ) nmol/L in model group( P ＜ 0.01 ).Plasma folate in low dose and high dose group did not show significant difference( P ＞ 0.05 ); ( 2 ) Apoptosis cell were 48.2 ± 9.1 in low dose group and 44.7 ±8.3 in high dose group, which were significantly lower than 75.8 ± 10.1 in model group (P＜0.01).However, apoptosis cell in low dose and high dose group did not show significant difference( P ＞0.05 ) ;(3 )significant difference( P ＞ 0.05 ); (4) bcl-2 mRNA and protein expression were 0.98 ± 0.49 and 0.89 ±0.52 in low dose group and 0.95 ± 0.38 and 0.92 ± 0.47 in high dose group which was significantly higher than 0.62 ± 0.20 and 0.45 ± 0.37 in model group ( P ＜ 0.01 ); bcl-2 expression in low dose and high dose group showed no significant difference ( P ＞ 0.05 ).Conclusions Folic acid has a protective role on neural activation and promoting bcl-2 gene and protein expression.

Objective:Occult breast cancer (OBC) accounts for 0.3%-1.0%of all breast cancers. Because of the rarity of this dis-ease, its treatment and prognosis remain unclear. Our study evaluated the treatment outcomes and prognostic factors associated with OBC. Methods:A total of 82 patients diagnosed with OBC based on available criteria were treated at the Cancer Hospital of Chinese Academy of Medical Sciences, Beijing, China, between January 1968 and June 2014. Except for 16 patients who were treated by needle biopsy or excisional biopsy only and were subsequently excluded, all of the cases reported were included in the study. Of the remaining 66 patients, one was male. Patient data, tumor characteristics, and treatment and outcome variables were evaluated. Overall survival (OS) and disease-free survival (DFS) were analyzed. A unicentric retrospective review of 66 patients with OBC was performed. Re-sults:The median follow-up was 75.5 months (7.0-328.0). No significant differences in OS and DFS were observed between patients who underwent mastectomy plus axillary lymph node dissection (Mast+ALND) and those who underwent breast conservation surgery (P>0.05). Univariate analysis revealed that nodal status is a significant prognosis factor of DFS (P=0.031). Conclusion:No significant difference in treatment outcomes between mastectomy+ALND and breast conservation surgery was observed. Nodal status may be an independent predictor of poor outcomes in OBC patients.
