ObjectiveTo assess the degree of pain in elderly patients with mechanical ventilation in ICU using critical-care pain observation tool(CPOT) and to choose the correct sedative and analgesic method.Methods 110 elderly patients in ICU after neurosurgery were divided into three assessment stages,every stage had two record points and total six points (T1-T6):the first stage (intubation and unconsciousness,T1-T2),the second stage (intubation and consciousness,T3T4 ) and the third stage(extubation and consciousness,T5-T6 ).Among them T1,T3and T5were nonnocuity assessment points of every stage,while T2,T4 and T6 were nocuity assessment points of every stage.The assessment time was one minute at every point.After recorded at every point in second and third stages,patients were asked to use the pain intensity descriptive scale (PIDS) themselves.CPOT,heart rate and mean arterial pressure (MAP) from T1 to T6 were recorded as well as PIDS from T3 to T6 in second and third stages.Results In the three stages,CPOT〔(26.8 vs.0.54,3.36 vs.1.20,2.78 vs.0.68) scores〕,HR〔(95 vs.85,94 vs.82,94 vs.84)beat/min〕 and MAP〔(95 vs.85,95 vs.87,94 vs.87)mm Hg〕 at T2,T4and T6 were higher than T1 (t=-42.89,-55.95,-55.38),T3 (t =- 5.52,- 11.33,- 11.78) and T5 ( t =- 5.54,- 9.95,- 11.33 ) ( P＜ 0.05 ).The PIDS at T4 and T6were higher than at T3and T5in the second and third stages 〔(2.52 vs.1.69,2.12 vs.1.44)scores〕 (P＜0.05).The correlation coefficient between CPOT and PIDS at T3 and T4 in the second stage were 0.49 and 0.58,respectively (P＜0.05),and between CPOT and PIDS at T5 and T6 were 0.52 and 0.59 in the third stage,respectively (P ＜ 0.05),and they both reached moderate correlation.ConclusionsCPOT may be an effective way to assess the degree of pain in elderly patients with mechanical ventilation at present.

Objective To transform knowledge organization systems (KOS) about traditional Chinese medicine (TCM) domain into standardized ontologies, in order to achieve the publication, sharing, and fusion of TCM KOS on the Web, and to further improve the organization and management of TCM knowledge. Methods Simple knowledge organization system (SKOS), a technical specification recommended by World Wide Web Consortium, was used to transform TCM KOS into publishable ontologies on the Web. Results Traditional Chinese medicine language system was transformed into an SKOS ontology, which was stored into a knowledge base that could support SPARQL (standard query language of the Semantic Web) query access, and provide concept, terminology, and knowledge services for Semantic Web applications, such as semantic wiki and semantic search via Web service interfaces. Conclusion This research preliminarily verifies the applicability of SKOS in TCM domain, and exemplifies the process of transforming TCM KOS into SKOS ontologies.

Objective To study the relationship of matrix metalloproteinase 7(MMP7)expression to the infiltration and metastasis of malignant melanoma.Methods Various concentrations(10,20,30 μmol/L)of heparanase antisense oligodeoxynucleotide (ASODN)was used to transfect human malignant melanoma cell line A375.Then,the transfected cells were subcutaneously inoculated into the right back of nude mice.Six weeks after the inoculation,transplanted tumors were isolated from the mice,and the levels of MMP7 protein expression were assessed by SP immunohistochemistry.The expression rate of MMP7 was also examined by SP immunohistochemistry in A375 cells and in tissue samples from patients with malignant melanoma(n=30),iunctional nevus(n=30)and normal human controls(n=15).Results The expression rate of MMP-7 was 83.33%(25/30),6.67%(2/30)and 0(0/15)respectively in malignant melanoma,iunctional nevus and normal skin tissue samples;there was a significant difierence in the positivity rate of MMP-7 between the malignant melanoma group and iunctional nevus group (x2=35.62,P=0.000)as well as normal control group(x2=28.12,P=0.000),but not between the junctional nevus group and normal control group(P＞0.05).The expression of MMP-7 in transplanted tumor was decreased to a varying degreee by three levels of ASODN,and the inhibitory effects of 30 mol/L ASODN were the strongest(P＜0.05).MMP-7 protein was also highly expressed in A375 cells.Conclusions The expression of MMP-7 in cutaneous malignant melanoma is higher than that in iunctional nevus and normal skin tissue.Hpa-ASPDN significantly inhibits the expression of MMP-7 in transplanted tumors in nude mice.MMP-7 is highly expressed in A375 cells.

Objective To investigate the expression and distribution of STAT3 in the retina during the early development of postnatal hamster. Methods Immunocytochemical method and Western blot analysis were used. Results The expression of STAT3 was found in all layers of the retina in all newborn hamsters,most pronounced in the ganglion cell layer(GCL),the inner plexiform layer(IPL)and the inner area of neuroblastic layer(NBL).With the development,the STAT3 immunoreactivity was gradually restricted in the cytoplasm and the nucleus of the retinal ganglion cells.The result of the Western blot showed that the STAT3 was highly expressed in the first week of postnatal development and then reduced gradually till the lowest point in the adulthood.Conclusion The expression of STAT3 protein may be closely related to the early development of the retina in the postnatal hamster.

Objective:To evaluate the effect of modified Tianma-Gouteng Decoction combined with conventional western medicine in the treatment of cerebral hemorrhage with syndrome of hyperactive liver yang causing wind. Methods:From May 2017 to December 2019, 120 patients of cerebral hemorrhage with syndrome of hyperactive liver yang causing wind were randomly divided into two groups, 60 in each group. The control group was treated with conventional western medicine treatment, and the observation group was with modified Tianma-Gouteng Decoction on the basis of the control group. Before and after treatment, the TCM symptom scores were evaluated. Serum norepinephrine (NE), epinephrine (E), dopamine (DA) were detected by ELISA. Serum MDA was detected by ELISA. Serum homocysteine (Hcy), endothelin (ET) were detected by fluorescence polarization immunoassay, the National Institutes of Health Stroke Scale (NIHSS) was used to assess the degree of neurological impairment, and Barthel index was used to assess activities of daily living. The rebleeding during the treatment was observed and recorded to evaluate the clinical efficacy. Results:The total effective rate was 90.0% (54/60) in the observation group and 70.0% (42/60) in the control group, with significant difference between the two groups ( χ2=7.500, P=0.006). After 3 and 6 weeks of treatment, the TCM syndrome score of the observation group were significantly lower than those in the control group ( t=10.670, 14.022, P<0.001). After treatment, NIHSS score of treatment group was significantly lower than that of control group ( t=5.736, P<0.01), Barthel index score of treatment group was significantly higher than that of control group ( t=10.559, P<0.01). After treatment, serum NE [(2 897.51 ± 241.65) pmol/L vs. (6 309.25±394.16) pmol/L, t=57.160], E [(1 352.45 ± 234.15) pmol/L vs. (4 131.20 ± 431.55) pmol/L, t=43.839] and DA [(623.59 ± 45.61) pmol/L vs. (950.61 ± 51.39) pmol/L, t=36.866] levels, serum SOD [(4.08 ± 1.05) C/μg·mgHb vs. (3.16 ± 1.02) C/μg·mgHb, t=4.868], MDA [(3.15 ± 1.41) μmol/L vs. (5.86 ± 1.31) μmol/L, t=10.907] levels, serum Hcy [(12.98 ± 2.41) μmol/L vs. (17.68 ± 2.26) μmol/L, t=11.019], ET [(51.36 ± 5.29) ng/L vs. (79.58±7.65) ng/L, t=23.502] in treatment group were significantly lower than those in the control group ( P<0.01); NO [(63.19 ± 3.87) μmol/L vs. (51.26 ± 3.59) μmol/L, t=17.506] in treatment group was significantly higher than that of the control group ( P<0.01). The incidence of rebleeding was 1.7% (1/60) in the observation group and 15.0% (9/60) in the control group, where the difference was statistically significant ( χ2=6.982, P=0.008). Conclusion:Modified Tianma-Gouteng Decoction combined with conventional western medicine therapy can protect the cerebral nerve function of patients with cerebral hemorrhage with syndrome of hyperactive liver yang causing wind, prevent the secondary ischemic brain injury after cerebral hemorrhage, and improve the clinical curative effect.

Objective: To evaluate value of application of intravascular ultrasound imaging (IVUS) in diagnosing borderline lesions in left anterior descending artery (LAD) and left main coronary artery (LM). Methods: According to results of coronary angiography (CAG) in 60 cases with coronary borderline lesions, including 20 cases in LM, 20 cases in proximal segment of LAD and 20 cases in middle segment of LAD, the diagnostic value of IVUS in coronary borderline lesion was evaluated. Results: Compared with CAG, mean diameter stenosis rate of each coronary artery [LM: (65.3l±7.81) % vs. (75.28±8.89) %，proximal segment of LAD: (66.67±8.79) % vs. (78.89±7.88) %，middle segment of LAD: (71.55±6.83) % vs. (75.3l±7.81) %, P<0.01 all] significantly increased in IVUS. The differences of detection rate of plaque calcification and plaque rupture were no significant between CAG and IVUS（＞0.05）. Conclusion: Different degrees of underestimation of coronary artery stenosis exist in CAG, especially in proximal segment of LAD. IVUS can be an effective complement to CAG.

Objective:To analyse the degree of equality of New Rural Cooperative Medical Scheme (NRCMS) in different economic regions. We provide a reference for equal development of the NRCMS and the reform of the political system and mechanism under the provincial-controlled county fiscal system. Methods:A typical province was chosen with provincial-controlled county fiscal system was fully implemented several years. We collected data on coverage, financing and compensation for the NRCMS from 2005 to 2011. We used the variable coefficient, uniformity coefficient, Theil Index for comprehensive evaluation. Results:Per capita financing has not reached the bottom line. From 2005 to 2011, inter-re-gional and intra-regional variation coefficient, Theil index of service coverage, financing level and hospital actual compen-sation has declined year by year. The degree of inequality in economically developed regions was greater than in less eco-nomically developed regions and economic medium region. Conclusion:The degree of equalization of the NRCMS in the province continuously improved. Innovation of provincial-controlled county fiscal system and mechanism provides a favora-ble environment and forming conditions for equalizing the development of the NRCMS. The paper suggested exploring and building fiscal classification step transfer payment institution and dynamic prediction model of the NRCMS, further optimi-zing financing mechanism, promoting the provincial management system of the NRCMS as soon as possible in order to pro-mote the equalization development.
