Objective To compare HER-2 state in breast cancer tissue deteced by fluorescent in situ hybridization (FISH) and immunohistochemistry (IHC) and analyze their correlation. Methods HER-2/neu protein expression and gene amplification were detected by FISH and IHC in 56 newly-diagnosed cases of female breast cancer from July 2008 to July 2009. Results Of the 56 patients, HER-2 protein expression (-), (+), (++), (+++) was 9 cases (16.1%), 29 cases (51.8%), 11 cases (19.6%) and 7cases (12.5%) respectively; 26 cases (46.4%) had HER-2 gene amplification while 30 cases (53.6%) didnt have. Type of HER-2 gene amplification was mainly HER-2(++) and HER-2(+++), and according gene amplification rate was 72 7% and 100%. HER-2 (+) gene amplification rate was 37.9 %(11cases) and no gene amplification was found in HER-2(-) tissue. The HER-2 positive rate using two methods had significant difference(χ2=19.778,P<0.01). HER-2(-) and HER-2(+++) had good consistency with the FISH results(Kappa=0.969),but HER-2(+) and HER-2(+ +) were poorly consistent with the FISH results(Kappa=0.271). Conclusions IHC is the preliminary screening method for detection of HER-2 expression. HER-2(-) and HER-2(+++) have good consistency with the gene amplification, and can guide clinical treatment. Some patients with HER-2(+) and HER-2(++) have HER-2 gene amplification. FISH is needed for targeted therapy.

OBJECTIVETo study the effect of high glucose and mannitol (osmotic control) on receptor activator of nuclear factor kappa B ligand (RANKL)-induced osteoclastogenesis and Notch2 expression using bone marrow macrophages (BMMs) from mice. Furthermore, the effect of Notch2 activation on RANKL-induced osteoclastogenesis with high glucose concentration was explored.
METHODSPreosteoclasts were cultured and exposed to sustained high glucose (0, 5, 10, 20, 40 mmol x L(-1)) levels to mimic diabetic conditions. Osteoclast formation was analyzed using tartrate resistant acid phosphatase (TRAP) assay. Expression of Notch2 gene was analyzed using real-time polymerase chain reaction. Constitutively over-expressed active Notch2, via stable transfection of exogenous ICN2 (intracellular fragment of Notch2) in preosteoclasts and the effect of Notch2 over expression on osteoclastogenesis was analyzed using Western blotting and TRAP staining.
RESULTSThe osteoclast number with 20 mmol x L(-1) glucose (110.3 +/- 6.8) and 40 mmol x L(1) glucose (72.0 +/- 8.0) was significantly less than the group with 20mmol x L(-1) mannitol (152.7 +/- 7.0) and 40 mmol x L(-1) mannitol (157.0 +/- 12.5). The relative gene expression of Notch2 with 20 mmol x L(-1) glucose (1.65 +/- 0.23) and 40 mmol x L(-1) glucose (1.10 +/- 0.11) was significantly less than the group with 20 mmol x L(-1) mannitol (2.82 +/- 0.28) and 40 mmol x L(-1) mannitol (2.42 +/- 0.27) (P < 0.05). The osteoclast number after Notch2 activation (ICN2-OE) with 20 mmol x L(-1) glucose (206.7+/- 7.8) and 40 mmol x L(-1) glucose (178.3 +/- 11.5) was significantly more than the control group (EMPTY) (102.3 +/- 8.7 and 76.0 +/- 10.1 respectively) ( P < 0.05).
CONCLUSIONNotch2 signaling activation may promote osteoclastogenesis under high glucose concentration.

Objective To investigate the changes of serum thyroxine level in obstructive sleep apnea-hy-popnea syndrome(OSAHS) patients and to assess the role of serum thyroxine in the development of OSAHS. Meth-ods Polysomnography was used to examine the patients with OSAHS and fasting plasma serum thyroxine level were higher in obese OSAHS patients than in obese controls[ (43.56±3.48)cm vs (38.33±3.08)cm,t =4. 258,P < 0.05 ], in non-obese OSAHS patients than in non-obese control group [ (40.50±1.05 )cm vs (36.17±3.13 )cm, t = 3. 146 ,P < 0.05 ] . The levels of FT3 was (6.35±3.15 ) pmol/L in obese OSAHS patients and ( 4.08±2.37 ) pmol/L in control subjects ( t = 2.203 ,P < 0.05 ). That was ( 3.42±0.57 ) pmol/L in non-obese OSAHS patients related with AHI and microarousal index (r = 0. 500, P < 0.05;r = 0.561, P < 0.05 ), and FT4 was also positively with neck circumference( t = 0.489, P < 0.05 ), TSH level was negatively correlated with neck circumference ( t = - 0.500, P < 0.05 ) and was positively correlated with the percentage of body fat ( r = 0.498, P < 0.05 ). Conclu-sions The FT3 levels are significantly higher in the OSAHS patients than that in control subjects, though all FT3 lev-els are normal, suggesting that there are possibility to have abnormal metabolism. At the same time, FT3 level is posi-tively correlated with neck circumference ,suggesting that the OSAHS patients' higher neck circumference is correla-ted with thyroxine.

OBJECTIVETo investigate the changing laws of serum high mobility group box 1 protein (HMGB1) in septic rats and intervention effect of Xuebijing on it.
METHODSLipopolysaccharide (LPS) (5 mg/kg BW) was intravenously injected into the tail vein of healthy male Wistar rats to prepare the sepsis rat model. In Experiment 1: 50 Wistar rats were randomly divided into three groups, i.e., the normal group (A, n=10); the LPS model group (B, n=10), the LPS +Xuebijing treatment group (C, n=30). Rats in the C group were further divided into three subgroups, i.e., 2 h before LPS injection (group C1), 2 h after LPS injection (group C2), and 8 h after LPS injection (group C3), 10 in each group. Blood samples were collected from the caudal vein to detect serum HMGB1 levels by Western blot at 4, 12, 24, 48, and 72 h after LPS injection. Experiment 2: 30 Wistar rats were equally divided into the LPS model group (D) and the LPS + Xuebijing treatment group (E), 15 in each group. They were treated as rats in the B group and the C1 group respectively. Five rats were sacrificed at 12, 24, and 48 h after LPS injection in the two groups. Blood as well as the tissue samples were harvested to measure such indices as ALT, AST, Cr, and BUN, as well as pathological changes of liver, lung, and kidney.
RESULTS(1) Compared with the A group, serum HMGB1 levels were higher at various time points in the B group (P < 0.05). Compared with the B group, serum HMGB1 levels at 12,24,48, and 72 h decreased in the C1, C2, and C3 groups. Besides, the decrease was more obvious at 24 h and 48 h.The decrement in the C3 group was less than that in the C1 and C2 groups (P < 0.05). (2) In the D group, ALT, AST, Cr, and BUN were significantly higher than those in the A group and reached the peak at 24 h (P < 0.05). Compared with the E group, AST, Cr, and BUN at 24 and 48 h, and ALT at each time point decreased significantly in the E group (P < 0.05). (3)The results of pathological section of liver, lung, and kidney showed local congestion and hemorrhage, cell edema/necrosis/degeneration, infiltration of inflammatory cells, damage of characteristic structures and so on; particularly serious lesion occurred at 24 and 48 h in the D group. The microscopic lesion was obviously alleviated in the E group than in the D group at corresponding time points.
CONCLUSIONSThe serum HMGB1 levels increased in septic rats, with late occurrence of peak value and longer duration of the high value. HMGB1 played an important role in excessive inflammatory response and multiple organ dysfunction. Xuebijing could reduce the serum levels of HMGB1, improve biochemical parameters, and attenuate severe inflammatory response of liver, lung, and kidney tissues in septic rats. Besides, the earlier use, the better effect obtained.

Objective To investigate the distribution of death among human immunodeficiency virus/acquired immuno deficiency syndrome(HIV/AIDS) cases in Guizhou Province from 1995 to 2017. Methods The HIV/AIDS death cases from 1995 to 2017 were downloaded from “Chinese National Comprehensive HIV/AIDS Prevention and care Information system” in Guizhou Province and were analyzed. Results From 1995 to 2017, Guizhou Province reported a total of 43 794 HIV/AIDS cases and 11 527 deaths according to current address. After excluding missing persons, the HIV/AIDS mortality rate of the province was 29.8%. The proportion of reported HIV/AIDS cases died in the same year ( 21995-2012=139.5, P<0.001; 22012-2015=28.2, P<0.001) and the proportion of HIV/AIDS cases ( 21995-2012=109.1, P<0.001; 22012-2014=57.2, P<0.001) who survived at the beginning but died later in the year all showed a trend being low-high-low. In the analysis of the detection history of death cases, the detection proportion of cluster of differentiation 4(CD4) T-cell and the proportion of antiviral treatment had been increasing year by year. The analysis of the cause of death found that the proportion of death caused by AIDS increased firstly and then declined, and the proportion of death due to excessive drug abuse showed a trend of declining year by year. Conclusions The mortality rate of HIV/AIDS in Guizhou Province was still high, and decreased rather slow. Expanding the coverage of HIV monitoring and screening is one of the key tasks of AIDS prevention and control. CD4+T-cell testing and free antiviral treatment should be strengthened to reduce the mortality rate of HIV/AIDS in Guizhou Province in the future.
