Objective To explore the protective effect of salidroside on early reperfusion in patients with acute cerebral infarction treated with urokinase intravenous thrombolysis.Methods 98 patients with acute cerebral infarction who were consistent with intravenous thrombolysis after screening were enrolled in the study.They were equally divided into the control group and the treatment group by sealed envelop method in one to one ratio.The control group received urokinase intravenous thrombolytic therapy on the basis of dehydration,anticoagulation,brain rehabilitation,regulating blood pressure,blood glucose and other conventional treatment.Based on the treatment in the control group,the treatment group was treated with Hongjingtian injection for 10 days.The serum malondialdehyde(MDA),superoxide dismutase(SOD),plasma endothelin-1(ET-1) and high sensitive C-reactive protein(hs-CRP),neurological deficit score(NIHSS),Barthel index and clinical effect in the two groups were observed.Results There were no significant differences in levels of MDA,SOD,ET-1,hs-CRP,NIHSS and Barthel index between the two groups before treatment (t=0.30,0.26,0.41,004,0.57,0.33,all P>0.05).After treatment,there were statistically significant differences between the control group and the treatment group in levels of MDA,SOD,ET-1,hs-CRP,NIHSS score and Barthel index[(7.54±1.14)nmol/mL vs.(6.04±1.21)nmol/mL,(92.42±15.28)U/mL vs.(108.54±19.24)U/mL,(64.5±7.4)pg/mL vs.(41.4±8.1)pg/mL,(3.84±1.04)μmol/L vs.(2.54±0.84)μmol/L,(16.5±5.4)points vs.(11.2±3.1)points,(62.1±12.4) vs.(71.4±10.4)](t=6.31,4.59,14.74,6.81,5.96,4.02,all P<0.01).The total effective rate of the treatment group was 91.84%,which of the control group was 63.39%,the difference was statistically significant(χ2=8.83,P<0.05).Conclusion Salidroside can relieve lipid peroxidation in patients with acute cerebral infarction,promote decomposition of oxyradical,reduce inflammatory reactions,improve neurological function and quality of life.The curative effect is significant.It has protective effect on early reperfusion in patients with acute cerebral infarction treated with urokinase intravenous thrombolysis.

Objective To explore the usage of anatomic al M-mode echocardiography in observing pulmonary artery motion curve of pulmonary hypertension patients.Methods The subjects included 21 pulmonary hypertension patients complicated with tricuspid valve insufficiency, and 21 controls whose age and gender matched with the patient group. The inner diameter of main pulmonary artery and right atrium, acceleration time of pulmonary valve Doppler signal and maximum velocity of tricuspid insufficiency (ACTpv) were measured during routine echo examination. From the maximum velocity of tricuspid insufficiency the pulmonary artery systolic pressure (PASP) was calculated. The pulmonary artery motion curve and pulsating amplitude of pulmonary artery wall (PAWPA) was observed and measured with a home-made anatomical M-mode echocardiography with instrument. Results PAWPA in the patient group was lower, and simultaneously complicated with broader pulmonary artery, larger right atrium and shorter ACTpv in comparison with normal group (all P

AIM:To investigate the protective effect of nerve growth factor combined with Ginkgo biloba extract on retinal ischemia-reperfusion (RIR) injury in rabbits with experimental high intraocular pressure.METHODS:Establishment of rabbit glaucoma ischemia reperfusion model.Twenty-four New Zealand white rabbits were randomly divided into three groups:nerve growth factor group, Ginkgo biloba extract group and combination group.Respectively, in the continuous administration of 1, 7, 14d.We observed the morphological changes of the tissues of the retina.The levels of superoxide dismutase(SOD), nitric oxide(NO) and malondialdehyde(MDA) in retinal tissue were measured.RESULTS:Respectively, first, in the continuous administration of 1, 7, 14d, the contents of MDA and NO in Ginkgo biloba extract group and nerve growth group were higher than that in combination group (P<0.05).Secondly, the SOD content of Ginkgo biloba extract group and nerve growth group were lower than that of combination group at each time point (P<0.05).At each time point, the number of HE staining of retinal ganglion cells (RGCs) showed that the loss of RGCs in the combination group was significantly lower than that in the other groups, and the ganglion cell count showed that the Ginkgo biloba extract group and the neuronal growth group were lower (P<0.05).CONCLUSION:Nerve growth factor combined with Ginkgo biloba extract has better protective effect on retinal ischemia-reperfusion injury.The mechanism may be related to the decrease of free radicals and increase the activity of SOD in retinal tissue.

Objective To evaluate the predictive value of plasma atrial natriuretic peptide (ANP) level on prognostic of patients with systemic inflammatory response syndrome by dynamic monitoring ANP levels.Methods Ninety-eight patients admitted to the intensive care unite were classified into survival group(n =78) and death group (n =20).The level of plasma ANP,procalcitonin,C-reactive protein and lactic acid were measured.Acute Physiology and Chronic Health Evaluation (APACHE) Ⅱ score were recorded.Results The plasma ANP level of patients in the death group was 0.40 (0.26) μg/L,significantly higher than that in the survival group(0.22(0.12) μg/L,P =0.000).Along with treatment scheme,the plasma ANP level decreased in survival group,and there were significant difference among three times (0.22 (0.12) μg/L,0.17 (0.09) μg/L,0.13 (0.11) μg/L,P =0.000).But there was no difference in ANP level of patients in death group along with the disease developing (0.38 (0.30) μg/L,0.39 (0.23) μg/L,0.39 (0.22) μg/L,P =0.99).ICU hospitalized time in survive group associated with APACHE Ⅱ score,ANP and PCT(r =0.735,0.628,0.487 respectively,P =0.000,0.001,0.021).Conclusion ANP is proved to be a good clinical index in prognostic evaluation of patients with sepsis.

Objective:To observe the interventative effect of Ziyin-Huatan Decoction by regulating exosomes on subcutaneous tumor of mice with gastric cancer. Methods:MGC-803 cells were randomly divided into exosome control group, low-dose group and high-dose group. The low-dose group and high-dose group were intervened with Ziyin-Huatan Decoction of 25 μg/ml and 100 μg/ml respectively. After 48 hours, the exosomes secreted by MGC-803 cells in each group were extracted. Twenty BALB/c male mice were randomly divided into exosome control group, low-dose Ziyin-Huatan Decoction group, high-dose Ziyin-Huatan Decoction group and blank control group, with 5 mice in each group. Except for the blank control group, the mice in the other groups were injected with exosomes extracted from the cells of the corresponding group through the orbit, 10 μg/time for each mouse, once every other day, a total of 15 times; the blank control group was injected with the same amount of PBS. Then SGC-7901 cells were inoculated into mice to establish a tumor model. The tumorigenic rate and body weight of mice were observed. The levels of CD31, VEGF and bFGF in tumor tissues were detected by immunohistochemistry. Results:Compared with the blank control group, the tumor weight [(170.00 ± 10.00) mg vs. (343.33 ± 20.82) mg] and the expression of CD31 (37.43 ± 0.55 vs. 63.30 ± 0.85), VEGF (11.37 ± 1.19 vs. 70.30 ± 0.72) and bFGF (43.77 ± 1.53 vs. 84.97 ± 1.86) in the high-dose Ziyin-Huatan Decoction group significantly decreased ( P<0.05). Compared with exosome control group, the expressions of CD31, VEGF and bFGF in low and high dose Ziyin-Huatan Decoction groups were decreased ( P<0.05). Conclusion:Ziyin-Huatan Decoction can significantly inhibit the growth of subcutaneous tumor of gastric cancer in mice by regulating exudation, which may be related to the inhibition of tumor angiogenesis.

In order to investigate the role of Th17 cytokines in the pathogenesis of psoriasis, reverse transcriptase-polymerase chain reaction (RT-PCR) was used to detect the expression of IL-17, IL-23 (p19/p40), and IL-6 in skin lesions and non-lesions of the patients with psoriasis and skin tissues of normal subjects. The results showed that the mRNA expression levels of IL-17, IL-23p19, IL-23p40 and IL-6 in psoriasis lesion were significantly higher than those of non-lesions (1.231 +/- 0.843 vs 1.003 +/- 0.044, 1.166 +/- 0.142 vs 0.765 +/- 0.133, 1.125 +/- 0.104 vs 0.730 +/- 0.103, 1.186 +/- 0.222 vs 0.976 +/- 0.122, respectively, all P < 0.05). Meanwhile, The expression levels of IL-17 mRNA, IL-23p19 mRNA, IL-23p40 mRNA and IL-6 mRNA were higher in non-lesions than those in normal skin tissues (1.003 +/- 0.044 vs 0.620 +/- 0.104, 0.765 +/- 0.133 vs 0.584 +/- 0.078, 0.730 +/- 0.103 vs 0.000 +/- 0.000, 0.976 +/- 0.122 vs 0.656 +/- 0.121, respectively, all P < 0.05). The overexpression of Th17 cytokines in the skin lesions of patients with psoriasis may indicate that Th17 cytokines play a very important role in the immunopathogenesis of psoriasis.

Objective : To investigate the AIDS-related knowledge and behaviors and health service demand among secondary vocational school students in Shanghai Municipality, so as to provide the evidence for formulating the HIV/AIDS health education and behavioral interventions among secondary vocational school students. Methods : Three secondary vocational schools were randomly sampled in Shanghai Municipality using a stratified cluster sampling method from September to November in 2019, and grade was stratified in each school. Then, a class was sampled from each grade, and all students in this class were sampled. Participants' demographics, AIDS-related knowledge, sexual behaviors, and health service needs for AIDS control were collected using questionnaires and descriptively analyzed. Results : Totally 2 078 questionnaires were allocated, and 2 022 questionnaires were recovered, including 2 013 valid questionnaires (99.55%). The respondents had a median age of 16 years (interquartile range, 2 years), and included 1 366 men (67.86%). A low awareness rate was found for “Self-testing may understand HIV/AIDS infection status” (40.83%) and “Mosquito bites fail to transmit HIV” (37.95%). There were 182 respondents with sexual behaviors (9.04%), including 47 respondents with use of condoms during each sexual behaviors (25.82%), 20 respondents with multiple sexual partner behaviors simultaneously (10.99%), and 21 respondents that had received HIV testing (11.54%). There were 807 respondents with questions about sex and reproductive health (40.09%), and 852 respondents that wished to acquire answers from professional network platforms and professionals (42.32%). Conclusions The awareness of HIV/AIDS transmission route and use of condoms is low among secondary vocational students in Shanghai Municipality, and there are high-risk behaviors for HIV/AIDS among students. The secondary vocational school students are most eager to obtain the answers from professional institutions and professionals if there are questions about sex and reproductive health.
