Objective To explore the diagnosis and treatment of phyllodes tumor of the breast. Methods Clinical data from 30 patients with phyllodes tumor confirmed surgically and pathologically were analyzed retrospectively. Results Of the 30 cases of phyllodes tumor, there were 16 cases of benign tumor, 9 cases of borderline tumor and 5 cases of malignant tumor according to the standard histological criteria. Local mass excision, total mastectomy, modified radical mastectomy and tumor mass excision were performed in 8, 8 and 13 patients, and 1 patient, respectively. A follow up of 20 cases for 1-24 years found 1 death, but all the others survived. Four patients out of the 20 patients underwent total mastectomy or modified radical mastectomy due to tumor recurrence. Conclusion The preoperative diagnosis of phyllodes tumor is difficult. Intraoperative frozen section examination of the suspicious lesions should be conducted. Multiple slices of the specimen should be performed. Surgical options are closely associated with the prognosis. Wide local excision or total mastectomy is recommended in surgical options.

ObjectiveTo explore the role of parameters of organ function during heat stroke (HS) on the prognosis, and to form the treatment strategy through an analysis of parameters of organ function during HS. Methods A retrospective study was conducted. Thirty-seven patients with HS (HS group) and 54 patients with mild-to-moderate stroke (stroke group) admitted to Zhejiang Xiaoshan Hospital from 2011 to 2014 were enrolled. The experimental results of organs function indicators for patients were recorded including:① cardiac markers:troponin I (TnI);② myocardium zymogram: creatine kinase (CK), MB isoenzyme of creatine kinase (CK-MB), lactate dehydrogenase (LDH), and aspartate aminotransferase (AST);③ renal function indexes: blood urea nitrogen (BUN), uric acid (UA), and serum creatinine (SCr);④ electrolyte: serum K+, Na+, and Cl-;⑤coagulation function: prothrombin time (PT), international normalized ratio (INR), activated partial thromboplastin time (APTT), thrombin time (TT), fibrinogen (FIB), and D-dimer;⑥ blood gas analysis: pH value, arterial partial pressure of carbon dioxide (PaCO2), base excess (BE), standard bicarbonate (SB), and actual bicarbonate (AB);⑦ routine blood test: blood platelet count (PLT);⑧ hepatic function: alanine aminotransferase (ALT). Abnormal rates of laboratory parameters of 37 HS patients were statistically analyzed. Various laboratory parameters of organs function as well as the initial value and extreme value (maximum or minimum value) during treatment of CK and PLT in HS patients were compared between two groups.Results The abnormal rates of 37 HS patients were more than 70%, including incipient value of TnI, CK, LDH, AST, serum Na+, ALT, D-dimer, PaCO2, AB, maximum value of CK, and minimum value of PLT, the abnormal rates being 73.0%, 70.3%, 81.1%, 78.4%, 78.4%, 70.3%, 70.3%, 70.3%, 75.7%, 81.1%, 75.7%, respectively. The abnormal rates of other parameters were less than 70%. There were significant differences in incipient value of TnI, CK, LDH, AST, serum K+, serum Na+, D-dimer, and PLT between HS group and mild-to-moderate stroke group [TnI (μg/L): 0.087 (0.026, 0.306) vs. 0.007 (0.004, 0.110),Z = -7.017,P = 0.000;CK (U/L): 392.30 (287.60, 524.10) vs. 137.10 (106.33, 607.80),Z = -7.930,P = 0.000; LDH (U/L): 317.98±122.74 vs. 207.85±57.71, t = 1.678,P = 0.000; AST (U/L): 94.90 (52.80, 155.80) vs. 26.10 (18.13, 317.40),Z = -6.157, P = 0.000; serum K+ (mmol/L): 3.46±0.65 vs. 3.86±0.57,t = 1.662,P = 0.001; serum Na+ (mmol/L): 129.75±7.34 vs. 138.79±4.26,t = 1.674,P = 0.000; D-dimer (mg/L): 2.53 (0.63, 6.00) vs. 0.30 (0.21, 9.71),Z = -5.084, P = 0.000; PLT (×109/L): 144.62±86.14 vs. 219.48±64.76,t = 1.669,P = 0.000]. There were also statistically significant differences in the initial value and extreme value of CK and PLT between HS group and mild-to-moderate stroke group [CK (U/L): 392.30 (287.60, 524.10) vs. 721.50 (546.30, 964.10),Z = -6.351,P = 0.000; PLT (×109/L):132.40±82.55 vs. 68.24±44.62,t = 1.688,P = 0.000].Conclusions HS can impair several organs and systems, having complications, and it is a heavy insult for body. Increasing of CK and decreasing of PLT has some value to assess illness changes. It is helpful of laboratory results for doctors to estimate complications on time.

Conclusions Dietary iodine intake plays an important role in the blood lipid metabolism. Iodine deficiency could increase while iodine excess could decrease the levels of serum TG, TC or LDL in mice. Monitoring the amount of iodine intake during sodium restriction should have an important role in effective prevention and treatment of cardiovascular disease.

Objective To observe the effects of iodine deficiency and iodine excess on the lipid metabolism in an experimental hypothyroid model of mice and to explore the roles of iodine independent of its role in thyroid hormones. Methods Female Balb/c mice were randomly divided into 6 groups: control, severe iodine deficiency (SID), mild iodine deficiency(MID), normal iodine (NI), 10-fold high iodine (10HI) and 50-fold high iodine(50HI), 10 in each group. The mice in control group were fed with low iodine forage, other mice were fed with low iodine forage containing 0.2% methylthiouracilum. All mice drank deionic water containing different concentrations of potassium iodide(KI). The iodine content in water was 326.79, 0, 196.08,326.79, 385621, 19 542.50 μg/L, respectively. After three months, thyroid hormones in the serum were determined by radioimmunoassay.Also, the blood samples were analyzed for total cholesterol (TC), triglyceride (TG), high density lipoprotein cholesteiol (HDL-C) and low density lipoprotein cholesterol (LDL-C) and measured enzymatically by automatic analyzer. Results①The levels of Tr4 in SID[(21.27 ± 9.63)μg/L], MID[(23.41 ± 3.93)μg/L], NI[(22.57 ±4.66)μg/L], 10HI [(21.07 ± 5.03) μg/L] and 50HI groups [(21.46 ± 5.90) μg/L] were distinctively decreased compared with control group[(42.15 ± 8.26)μg/L, all P ＜ 0.01]. There were no statistical significant differences of TT3 between different groups (F = 0.99, P > 0.05 ). ②The level of TG in 10HI group [ ( 1.17 ± 0.16)mmol/L ] was obviously decreased compared with control [(1.39 ± 0.22 )mmol/L] and NI groups[(151 ± 0.22)mmol/L, all P＜ 0.05].Both TG and TC in 50HI group[(1.18 ± 0.22), (1.78 ± 0.15)mmol/L] were significantly decreased compared with control [( 1.39 ± 0.22), (2.14 ± 0.37)mmol/L] and NI groups [(1.51 ± 0.22), (2.00 ± 0.15)mmol/L, all P ＜ 0.05].The difference of serum HDL-C and LDL-C between the groups was not significant(F = 0.55,0.54, all P ＞ 0.05 ).Conclusions Dietary iodine plays a role in the metabolism of serum lipids independent of thyroid hormones.Thus, monitoring the amount of iodine intake during sodium restriction should also be taken extremely important for effectively prevention and cure of cardiovascular disease.

OJECTIVETo observe the effect of tianma gouteng decoction (TGD) on the endothelial function and the renal protein expression of spontaneously hypertensive rats, and to analyze its possible mechanism.

METHODSTotally 18 6-week-old SHR were randomly divided into 3 groups according to randomized block design, the SHR control group, the TGD group, and the captopril group, 6 in each group. Meanwhile, Wistar Kyoto (WKY) rats of the same age were recruited as a WKY control group. Rats in the TGD group were administered with TGD at the daily dose of 10. 260 g/kg. Rats in the captopril group were administered with captopril at the daily dose of 3. 375 g/kg. 2 mL/100 g distilled water was administered to rats in the SHR control group and the WKY control group. All medication was performed by gastrogavage once per day till rats were 24 weeks old. Changes of blood pressure were measured once per two weeks. The relaxation of the thoracic aorta and the superior mesenteric artery was determined by vascular ring in vitro to reflect the endothelial function. The total renal protein was separated by two-dimensional electrophoresis (2-DE). The significantly deviated protein was verified by Western blot.

RESULTS(1) Compared with the SHR control group, blood pressure was significantly lowered in rats (10 - 24 weeks old) of the captopril group (P <0.01, P <0.05). The hypotensive effect of TGD was obvious at the beginning of hypertension (10 -12 weeks) (P <0. 01). But along with the progression of hypertension, its hypotensive effect was not obvious (P>0. 05). (2) Compared with the SHR control group, the relaxation of the superior mesenteric artery was obviously improved in the TGD group (P <0. 05); the relaxation of the thoracic aorta and the superior mesenteric artery was obviously superior in the WKY control group (P <0. 01, P <0. 05). But there was no statistical difference in each relaxation index between the captopril group and the SHR control group (P >0. 05).(3) RESULTS: of 2-DE found 16 significantly differential renal protein, mainly involved nitric oxide (NO) system, oxidative stress, and cytoskeleton-related proteins. Results of Western blot showed that TGD could significantly improve expressions of Cu-Zn superoxide dismutase (SOD), N(G, N(G)-dimethylarginine dimethylaminohydrolase 2 (DDAH2), and pterin-4-alpha-carbinolamine dehydratase 1 (PCBD1) (P <0. 05).

CONCLUSIONGTD could protect the endothelial function of the superior mesenteric artery in SHR, and its intervention mechanism of hypertension induced early renal injury might be relevant to regulating the NO system and antioxidative stress.
