Objective To investigate the changes of hematoma and perihematomal edema in spontaneous hypertensive rats (SHRs),as well as the correlation between blood pressures and perihematomal edemaMethods A total of 24 6-month-old male SHRs were included.They were randomly divided into intracerebral hemorrhage 1-,3-,5-,and 7-day groups (n =6 in each group).Blood pressure was determined by tail-cuff sphygmomanometry.Collagenase Ⅳ was injected into caudate nucleus in order to induce a model of intracerebral hemorrhage.Magnetic resonance T2 weighted imaging was used to observe hematoma and perihematomal edema.Results On day 1 after modeling,the blood pressure was decreased significantly compared to that before modeling,and it was elevated gradually on day 3.Parallel profile test showed that the overall profile was parallel between the change rate of blood pressure and the change rate of perihematomal edema volume (F =2.820,P =0.063).The coincident profile test showed that both the overall profiles did not coincide (F =10.961,P =0.000).The change rate of systolic blood pressure was significantly positively correlated with the change rate of perihematomal edema volume (r =0.527,P =0.024) and the change rate of perihematomal edema volume (r =0.755,P =0.000) showed a significant positive correlation.Conclusions Brain edema appeared and expanded rapidly on the day of intracerebral hemorrhage in SHRs.It reached the peak on day 3,and then dissipated gradually.The blood pressure decreased significantly on day 1 after intracerebral hemorrhage,and it began to increase from day 3 till day 7.The changing trends of the blood pressure and perihematomal edema volume were parallel to each other,and the change rate of systolic blood pressure and the change rate of perihematomal edema volume showed a positive correlation.

OBJECTIVE:To provide reference for improving pharmaceutical consultations and the quality of pharmaceutical care. METHODS:The records of pharmaceutical consultations were collected from medication consultation center of Huilong-guan district in our hospital during Jan. 2014-Dec. 2016,and then summarized in terms of consultants composition,consultation form,consulting contents and drugs consulted,while Pareto Diagram was used to analyze the main and minor factors of consult-ing contents. RESULTS:The medication consultation center provided pharmaceutical consultations 20353 cases during 2014-2016. Main consultants were patients (20039 cases,98.5%). A total of 6307 persons were involved,mostly female (3646 persons,57.8%). Face to face was the most common consulting method (19440 cases,95.5%). There were 13 types of consulting contents,among which usage and dosage and guidance for special formulation use were the main factors,including 10392 cases (51.1%) and 3844 cases (18.9%). Among 20353 cases of pharmaceutical consultations,18874 cases of in-volved drugs,and involved 11 categories,mostly respiratory drugs (11756 cases,62.3%). CONCLUSIONS:Usage and dos-age and guidance for special formulation use are the main contents of pharmaceutical consultations in the hospital district. The services of pharmaceutical consultations for patients,physicians and nurses provided by pharmacists can solve the questions on medications,and can promote rational drug use in clinic.

Objective To study the expression of Rho kinase and its functional activation in lung tissue from hypoxic pulmonary hypertension(HPH) rat model,and the effects of fasudil on HPH.Methods Seventy-two male Spraque-Dawley rats were randomly divided into the control group,hypoxic model group,and fasudil-intervention group[group with hypoxia and fasudil for 15 mg/(kg?d)],respectively.Mean pulmonary arterial pressure(mPAP) and right ventricle hypertrophy index(RVHI) were measured.Expression of Rho kinase mRNA and protein were examined by reverse transcriptase-polymerase chain reaction(RT-PCR) and Western blot,respectively.The phosphorylation of binding subunit of myosin phosphatase(MBS)-a substrate of Rho kinase was detected by Western blot and defined,as the mark of functional activation of the kinase.Results The expression of Rho kinase mRNA in hypoxic model group was markedly upregulated even before the onset of the third day after the experiment(HPH),and it was much lower in rats of fasudil group than that of hypoxic model group.The phosphorylation of MBS was significantly higher in hypoxic model group than that in control group,and it was positively correlated with the mPAP and RVHI(all P

In the 1960s, modern science began involving the essence of heat syndrome, but there have still no in-depth systematic studies on pathological mechanisms of heat syndrome and action mechanisms of cold and cool herbs. In this study, the animal model with heat syndrome was set up by feeding herbs with hot property, and then cold and cool herbs was applied in the experimental therapy. The two-dimensional electrophoresis and mass spectrometry technologies were adopted to compare the liver mitochondria proteome of the rats of the heat syndrome model and the ones treated with cold and cool herbs, so as to discover specificity-related proteins after heat syndrome and treatment with cold and cool herbs.

OBJECTIVETo study the effect of Zhusha Anshen pill, cinnabar, HgS, HgCl2 and MeHg on the gene expression of renal transporters in mice.

METHODHealthy male mice were given equivalent physiological saline, Zhusha Anshen pill (1.8 g · kg(-1), containing 0.17 g · kg(-1) of mercury), cinnabar (0.2 g · kg(-1), containing 1.7 g · kg(-1) of mercury), high dose cinnabar (2 g · kg(-1), containing 1.7 g · kg(-1) of mercury), HgS (0.2 g · kg(-1), containing 0.17 g · kg(-1) of mercury), HgCl2 (0.032 g · kg(-1), containing 0. 024 g · kg(-1) of mercury), MeHg (0.026 g · kg(-1), containing 0.024 g · kg(-1) of mercury), once daily, for 30 d, measuring body mass gain. 30 days later, the mice were sacrificed. The mercury accumulation in kidneys was detected with atomic fluorescence spectrometer. Expressions of Oat1, Oat2, Oat3, Mrp2, Mrp4, Urat1 were detected with RT-PCR.

RESULTCompared with the normal control group, a significant accumulation of Hg in kidney in HgCl2 and MeHg groups was observed (P <0.05), but these changes were not found in other groups. Compared with normal control group, mRNA expressions of Oat1 and Oat2 were evidently lower in HgCl2 and MeHg groups, but mRNA expressions of Mrp2 were apparently higher in HgCl2 group (P <0.05), mRNA expression of Mrp4 was significant higher in HgCl2 and MeHg groups, and mRNA expression of Urat1 was apparently lower in MeHg group.

CONCLUSIONHgCl2 and MeHg groups show significant difference from the normal group in mercury accumulation in kidneys and gene expression of kidney transporters, but with no difference between other groups and the normal group. Compared with HgCl2 and MeHg, cinnabar and its compounds could cause lower renal toxicity to mice.

Objective To observe the protective effect of N-NAC on radiation-induced lung injury. Methods 86 cases of thoracic neoplasm patients were chosen and randomly divided into two groups,group RT +N(n =43)and group RT(n =43).Two groups were observed by CT after radiotherapy.Acute and chronical toxicities were graded by RTOG.TGF-β1,IL-1,IL-4,TNF were observed before and after the radiotherapy.Results After 3 monthsof radiotherapy,RTOG≥2 was 23.4%(RT +N),while RTOG≥2 was 53.1%(RT).there was significant differencebetween the two groups(P <0.01).At 6,9 and 12 months,fibrosis was present in 28.4%,25.4%,22.4% receivingRT vs 58.4%,54.4%,52.4% receiving RT +N,there was significant difference between the two groups(P <0.05).TGF-β1,IL-1,IL-4,TNF were observed which showed that The RT +N were lower than RT.Conclusion N-NAC can reduce incidence rate of lung injury in radiotherapy,and can reduce the content and the release of TGF-β1,IL-1,IL-4,TNF.

Objective To investigate the affecting factors of interventricular septum (IVS) swing by study of the mechanical model of the respiration-driven variation of cardiac function using echocardiography.Methods In present study,the equivalent mechanical model of septal swing in previous study was used.By changing the end-diastolic pressure difference between the simulated right and left ventricles and simulated intrapericardial pressure,the subsequent influences on IVS swing using echocardiography were observed.Results Under the rhythmic respiratory intrathoracic pressure change(RIPC)(0--4 mm Hg,1 mm Hg =0.133 kPa),the swing amplitude of simulated IVS increased with decrease of the simulated end-diastolic pressure difference between the simulated right and left ventricles (2.2-17.6 mm).With increasing of the simulated intrapericardial pressure,the simulated right ventricle and left ventricle collapsed in succession,the swing amplitude of simulated IVS also increased to a maximal amplitude of 22.4 mm.Conclusions The affecting factors of IVS swing including the magnitude of RIPC,the end-diastolic pressure difference between the two ventricles and the intrapericardial pressure.
