The paper first analyzes the intrinsic need for cultural integration in hospital regrouping and sums up its content, including the integration of values, management ideas, institutional cultures and institutional frameworks. It then introduces some methods of cultural integration in hospital regrouping, such as running in on the basis of respecting human nature, resolving conflicts on the basis of being mutually tolerant, and merging completely on the basis of optimizing means of integration. The paper points out that success or failure of cultural integration in hospital regrouping depends on the thinking of the leaders. For this reason, it is imperative to enhance integration awareness and improve integration capability.

Objective To observe the stellate ganglion block (SGB) on obstructive sleep apnea syndrome (OSAS) combined the curative effect of sleep respiration and blood pressure control in patients with hypertension.Methods Incorporating meets the criteria for the OSAS patients with high blood pressure in hospital order randomly assigned into normal group and experimental group and routine group was given antihypertension drugs,adjustment in lifestyle,continuous positive airway pressure (CPAP) treatment,the experimental group on the basis of conventional treatment at the same time give SGB to intervene.Using t test on admission and intervention were compared after a period of treatment in patients with sleep apnea and blood pressure control,using 2 test comparison blood pressure control rates of two groups patients.Results Compared with normal group,the experimental group after intervention in a course of apnea hypoventilation index (AHI),SaO2 and 24 h mean arterial pressure were obviously improved,the difference was statistically significant (P＜0.05).Conclusion SGB as a new treatment method,not only can improve clinical symptoms in patients with OSAS,but also make the patients get better control of blood pressure.

OBJECTIVETo explore the expression and clinical significance of Semaphorin4D (Sema4D) mRNA in peripheral blood lymphocyte, Sema4D on platelet surface, soluble Sema4D (sSema4D) in plasma in patients with cerebral infarction.

METHODSTaking 299 patients with cerebral infarction as the case group while 195 healthy adults as the control group. The mRNA expression of Sema4D was detected by Real-time PCR, and Sema4D expression on platelet by flow cytometry, sSema4D by ELISA. Then, the expression of Sema4D on platelet surface and the concentration of sSema4D in plasma of the 195 selected patients following 2 weeks' treatment were tested.

RESULTSThe expression of Sema4D mRNA significantly increased in the case group \[(2.23, 2.66)×10(4) IU/ml\] than in the control group \[(0.49, 0.53)×10(4)IU/ml\] (P < 0.01). The level of Sema4D on platelet surface in the case group (191.62 ± 46.56) significantly decreased than in the control group (303.33 ± 112.66) (P < 0.01). But the concentration of sSema4D in plasma in the case group \[(1.34 ± 0.56) µg/L\] was obviously higher than in the control group \[(0.61 ± 0.31) µg/L\] (P < 0.01). The expression of Sema4D on platelet was obviously relevant with the concentration of sSema4D in plasma in the case group with the correlation coefficient as 0.328 (P < 0.01). The expression of Sema4D on platelet obviously peaked up following 2 weeks' routine therapy in the case group, which was close to that in the control group. Meanwhile the concentration of sSema4D in plasma was downward corrected to the normal in the case group.

CONCLUSIONThe increased expressions and plasma levels, and reduced expressions on platelet of Sema4D in acute period, which returned to normal 2 weeks after treatment in the case group may be related to the occurrence of acute cerebral infarction, reflecting the development process of cerebral infarction.

OBJECTIVETo study the alteration of protein Z (PZ) in patients with cardio-cerebral thrombotic diseases, its clinical significance and relations with FX.

METHODSPZ and FX:Ag were measured by ELISA, and plasma FX:C by first stage method. In 170 patients with acute ischemic stroke (AIS), 40 acute myocardial infarction (AMI) and 60 healthy adults as contrast, PZ, FX:C and FX:Ag were measured and compared between incipience and recurrence, different ages and genders.

RESULTSIn AIS and AMI groups, PZ levels decreased significantly to (940.02 +/- 229.82) microg/L and (1071.44 +/- 180.52) microg/L, respectively \[the contrast group was (2257.97 +/- 479.76) microg/L, P < 0.001\]. But FX:C and FX:Ag raised to (136.73 +/- 34.93)% and (135.54 +/- 54.39)% in AIS group; and to (139.53 +/- 29.18)%, (129.75 +/- 21.91)% in AMI group, respectively, while in the contrast group they were (94.33 +/- 22.00)% and (77.22 +/- 13.19)% (P < 0.001). In the comparative research between the AIS group, AMI group and the contrast group, PZ level was clearly found to negatively relate to the level of FX:C and FX:Ag (P < 0.001). Meanwhile, PZ level, FX:C and FX:Ag in recur-AIS group and recur-AMI group exhibited significant differences (P < 0.05) from those in the primary AIS and AMI groups, suggesting that the decrease of PZ levels reflected the pathological process of the disease. In addition, PZ level gradually decreased with the increase of age (P < 0.05), while FX:C and FX:Ag had no relations with age (P > 0.05). No correlation was found in sex with PZ level, FX:C, FX:Ag (P > 0.05).

CONCLUSIONPZ level was significantly decreased in AIS and AMI patients and was negatively related to FX:C and FX:Ag. The mechanism leading to FX increase may partially related with the decreased of PZ. PZ level was different in the primary and recurrent disease and was gradually decreased with the increase of age. Lack of PZ might be a etiological factor of cardio-cerebral thrombotic diseases.

BACKGROUNDThree randomised trials have demonstrated that combining bevacizumab with first-line chemotherapy significantly improves progression-free survival versus chemotherapy alone in HER2-negative locally recurrent/metastatic breast cancer (LR/mBC). However, data from Chinese populations are limited and possible differences between ethnic and geographic populations are unknown. This study was conducted to determine whether there are differences in safety and efficacy in patients with HER2-negative LR/mRC between Chinese and Western populations after they receive first-line bevacizumab combined with taxane-based therapy.

METHODSIn the single-arm, open-label, Avastin Therapy for Advanced Breast Cancer (ATHENA) study (NCT00448591), patients with HER2-negative LR/mBC received first-line bevacizumab (investigator's choice of 10 mg/kg every 2 weeks or 15 mg/kg every 3 weeks) combined with taxane-based therapy. The primary endpoint was safety profile and the secondary is time to progression (TTP). A subpopulation analysis was conducted to assess safety and efficacy in Chinese patients.

RESULTSOf 2264 patients treated in ATHENA, 202 were enrolled in China. Bevacizumab was combined with docetaxel in 90% of Chinese patients and paclitaxel in 10%. The most common grade 3/4 adverse events were diarrhoea (in 5.0% of patients) and hypertension (in 2.5% of patients). Grade 3/4 proteinuria occurred in 0.5%. After median follow-up of 17.6 months and events in 56% of patients, median TTP was 9.0 months (95%CI, 8.4-11.1). Overall survival data were immature.

CONCLUSIONSWe found no evidence of increased bevacizumab-related toxicity or reduced efficacy in Chinese LR/mBC patients receiving first-line bevacizumab-taxane therapy compared with predominantly Western populations. The safety profile was generally similar to previously reported LR/mBC trials. Subtle differences may be attributable to different lifestyle and cardiovascular risk factors in Chinese patients compared with the overall population. It appears reasonable to extrapolate findings from bevacizumab-based randomised trials to Chinese populations.

OBJECTIVE: To study the inhibitory effect of HDAC6 on proliferation of human leukemia KG1α and to explore its mechanism by ERK signaling pathways. METHODS: .The siRNA interference technology was used to inhibit the HDAC6 gene expression; the expression of HDAC6 and prateins of ERK signal pathway was detected by Western blot; the cell proliferation ability was detected by colony forming experiment and trypan blue staining; cell cycle was detected by FCM; and the expression of Ki67 was detected by immunofluorescence. RESULTS: Western blot showed that HDAC6 expression was up-regulated in leukemia cell lines in comparison with the healthy volunteers and bone marrow stromal cells (P＜0.05). Knockdown of HDAC6 significantly inhibited the proliferation and colony formation ability of leukemia cells, promoted cell arrest at G/G phase. The Western blot and immunefluorescence showed that knockdown of HDAC6 suppressed the expression level of Ki67, CDK4, Cyclin D1 and enhanced the expression level of p16, p21, p-ERK (P＜0.05). CONCLUSION Knockdown of HDAC6 significantly inhibits the proliferation, arrest the cell cycle at G/G phase, and its mechanism probably relates with the activation of ERK signaling pathway.

OBJECTIVETo evaluate the consciousness of health emergency and the abilities on self- and mutual medical aids among the public at the community level, as well as the community responses on health-related emergencies and other factors.

METHODSRandom equidistant sampling method was used to extract 617 households before choosing a family member sampled by Kish Grid method. All the members were investigated face to face on a questionnaire-"Health emergency and related ability regarding self and mutual medical aids of the residents". Data were entered into computer database by using software Epi Data 3.1 and were analyzed by SPSS 21.0.

RESULTSAmong the 617 households under survey, 47.84% of the public had general awareness on health-related emergencies. Regarding the following items as:prevention and isolation strategies of infectious disease, on safely procedures of earthquake and fires, on prevention of food poisoning, on prevention and first aid of emerging infectious diseases etc., the rates of awareness were 65.04%, 62.92%, 43.62% and 18.79% respectively. Proportions of households which had the first aid supplies were:first aid medicine box as 56.08%; fire extinguisher as 43.60%; spare water and food as 39.40%; having facilities as ropes, whistles and smoke masks for escape were all less than 15%. Rates of awareness on the following items as: correct use of gas switch as 81.52%, knowing the location of the circuit with gear and the fire hydrant as 74.39% and 35.98% , respectively. The correct disposal rates of the residents on the following items were:electric shock and falls (89.63%), patients of infectious diseases (83.31%), gas poisoning (82.98%), suspected symptoms on infectious diseases(82.66%), explosion and burns (66.78%), scald (62.72%)and sprain (57.05%). Scores on the related abilities were as follows: emergency(7.65, out of 10 points), escape(3.55, out of 5 points), self- and mutual medical aids (10.71, out of 16 points). Proportions of having learned and applied of first aid techniques among residents on the following items were:artificial breathing, chest compressions and cardiopulmonary resuscitation were all less than 10%. Level of knowing the first aid techniques was correlated with age and culture of the residents (P < 0.05).

CONCLUSIONBoth consciousness on health emergency and the abilities on self- and mutual medical aids were low among the community public, suggesting that both the government and pubic should pay more attention to the role of the abilities on self- and mutual medical aids.

OBJECTIVE: To study the promoting-apoptosis effect of HDAC6 on the human leukemia cells and its mechanism. METHODS: The siRNA interference technology was used to inhibit the expression of HDAC6 gene, the RT-PCR and Western blot were used to detect the expression of HDAC6 and related signal pathway proteins respectively, the flow cytometry and Hoechest staining were used to detect the apoptosis and morphology changes of K562 cells. RESULTS: Compared with the periphal blood monocyte and bone marrow stromal cells of healthy volunteers, the expression level of HDAC6 in leukemia cell lines was up-regulated significantly(P<0.05); the flow cytometry and Hoechest staining showed that after interference of HDAC6 gene, the apoptosis of K562 cells increased, moreover the cell morphology was changed; the Western blot detection showed that the interfering HDAC6 increased BAX/BCL-2 ratio and cleaved caspase 3 expression, and activated the MAPK, ATK, ERK signaling pathway. CONCLUSION The interferance of HDAC6 can promote the K562 cell apoptosis, its mechanism may relate with activation of MAPK signaling pathway.

OBJECTIVE: To investigate the therapeutic effect of Yixin Ningshen Tablet (YXNS) on comorbidity of myocardial infarction (MI) and depression in rats and explore the underlying mechanism. METHODS: The Sprague-Dawley rats were randomly divided into 5 groups with 7 rats in each group according to their weights, including control, model, fluoxetine (FLXT, 10 mg/kg), low-dose YXNS (LYXNS, 100 mg/kg), and high-dose YXNS (HYXNS, 300 mg/kg) groups. All rats were pretreated with corresponding drugs for 12 weeks. The rat model of MI and depression was constructed by ligation of left anterior descending coronary artery and chronic mild stress stimulation. The echocardiography, sucrose preference test, open field test, and forced swim test were performed. Myocardial infarction (MI) area and myocardial apoptosis was also detected. Serum levels of interleukin (IL)-6, IL-1β, tumor necrosis factor-α (TNF-α), 5-hydroxytryptamine (5-HT), adrenocorticotrophic hormone (ACTH), corticosterone (CORT), and norepinephrine (NE) were determined by enzyme linked immunosorbent assay. The proteins of adenosine 5'-monophosphate -activated protein kinase (AMPK), p-AMPK, peroxisome proliferator-activated receptor gamma coactivator-1α (PGC-1α), and nuclear respiratory factor 1 (NRF1) in heart were detected by Western blot analysis. The expression levels of TNF-α, IL-6, indoleamine 2,3-dioxygenase (IDO1), kynurenine 3-monooxygenase (KMO), and kynureninase (KYNU) in hippocampus were detected by real-time quantitative polymerase chain reaction. RESULTS: Compared with the model group, the cardiac function of rats treated with YXNS improved significantly (P<0.01). Meanwhile, YXNS effectively reduced MI size and cardiomyocytes apoptosis of rats (P<0.01 or P<0.05), promoted AMPK phosphorylation, and increased PGC-1α protein expression (P<0.01 or P<0.05). HYXNS significantly increased locomotor activity of rats, decreased the levels of TNF-α, IL-6 and IL-1β, and increased the serum levels of 5-HT, NE, ACTH, and CORT (all P<0.05). Moreover, HYXNS decreased the mRNA expressions of IDO1, KMO and KYNU (P<0.05). CONCLUSIONS YXNS can relieve MI by enhancing myocardial energy metabolism. Meanwhile, YXNS can alleviate depression by resisting inflammation and increasing availability of monoamine neurotransmitters. It may be used as a potential drug to treat comorbidity of MI and depression.
