ZPS score:Shenqi fuzheng injection combined with chemotherapy group was lower than chemotherapy alone(-17 398.77 vs. 384 513.00). Shenqi fuzheng injection combined with chemotherapy group was lower than chemotherapy alone group in average cost per 1 QALYs(1 313 326 yuan vs. 13 374 365 yuan). CONCLUSIONS:Compared with chemotherapy alone group,Shenqi fuzheng injection combined with chemo-therapy can effectively improve the quality of life,and it is worth of spending more money on Shenqi fuzheng injection from the perspective of the pharmacoeconomics.

ObjectiveTo evaluate prognosis and its clinical factors in patients with primary pontine hemorrhage. Methods Patients with primary pontine hemorrhage who were hospitalized in the First Affiliated Hospital of Wenzhou Medical College within 24 hours after stroke onset between April 2007 and April 2009 were registered conscutively. The patients were followed up for one year. Kaplan-Meier methods were used to analyze survival rate. Cox proportional hazards model was used to study risk factors for 1-year mortality. ResultsA total of 41 patients with primary pontine hemorrhage were studied. Their mean age was (63.5 ± 10. 1 ) years.The overall 1-year mortality rate was 61.0％, the median survival time was (80. 0 ±54.4) days (95％ CI 0-186. 64). After one-year follow-up, the mortality rate in patients with primary dorsal pontine hemorrhage( 18.2％ ) was significantly lower than that in patients with primary ventral pontine hemorrhage(72. 7％ ; x2 = 8. 800, P = 0. 003 ). Patients with massive primary pontine hemorrhage had significantly higher mortality rate than patients with dorsal primary pontine hemorrhage( x2 = 8. 927, P =0. 003). The average hematoma volume of the survivor group and mortality group was (3. 043 ± 1. 718) ml and (5. 984 ± 2. 707) ml, respectively, showing statistical significance (t = 3. 661, P = 0. 001 ). Analysis with Cox proportional hazards model showed that the risk factors associated with mortality were hematoma location ( RR = 2. 428, 95 ％ CI 1. 055-5. 587 ), hematoma volume ( RR = 1. 283, 95 ％ CI 1. 044-1. 577 ),GCS score on admission(RR =3. 389, 95％ CI 1. 177-9. 756). Patients with pontine hematomas in dorsal had a significantly better outcome than in other locations.Conclusions The survival and prognosis in primary dorsal pontine hemorrhage are better than with hemorrhaging in other parts of pontine. A significant correlation was observed between poor prognosis and hematoma volume, hematoma location and GCS score on admission.

Objective To investigate the correlation between matrix metalloproteinase-3 (MMP-3)serum level and polymorphism(5A/6A) and the stability of carotid plaque in Chinese Han population.Methods Two hundred and eighty acute cerebral infarction patients from the department of neurology of Taizhou Hospital were divided into carotid vulnerable plaque group and carotid stable plaque group according to the results of carotid B-mode uhrasonngraphy.Serum MMP-3 level waa measured by means of enzyme-linked immunosorbent assay (ELISA).At the same time, genotype was determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) for the common 5A/6A functional promoter polymorphism of the MMP-3 gene.The serum MMP-3 level and genotype frequencies of the MMP-3 gene between the two groups were analyzed.Results The genotype frequencies of the MMP-3 gene 5A/6A polymorphism of the two groups were in Hardy-Weinberg equilibrium The genotype distribution of the MMP-3 promoter 5A/6A polymorphism between the carotid vulnerable plaque group and the carotid stable plaque group was significantly different(χ2 =6.13, P =0.01, OR = 1.90, 95% CI 1.14-3.15).The frequencies of 5A allele were 20.6% and 12.8% in the carotid vulnerable plaque group and the carotid stable plaque group respectively (χ2=6.09, P=0.01, OR =1.76, 95%CI 1.12-2.77).Serum level of MMP-3 in the carotid vulnerable plaque group was higher than that in the carotid stable plaque group (t = 3.39, P =0.00).Conclusion The present findings suggest that serum level of MMP-3 and genetic polymorphism of 5A/6A in MMP-3 promoter are related with carotid vulnerable plaque in Chinese Han population and 5A allele may be a susceptible predictor of carotid vulnerable plaque.

OBJECTIVETo investigate the association of matrix metalloproteinase-3 (MMP-3) serum level and the promoter 5A/6A polymorphism of the MMP-3 gene with atherosclerotic cerebral infarction (ACI) in a Chinese Han population.

METHODSTwo hundred and fifteen patients with acute ACI from the Department of Neurology of Taizhou Hospital and 226 healthy controls were included in the study. Serum MMP-3 level was measured by enzyme-linked immunosorbent assay (ELISA). Genotype was determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) for the common 5A/6A functional promoter polymorphism of the MMP-3 gene.

RESULTSThe genotype distribution of the MMP-3 promoter 5A/6A polymorphism between the ACI patients group and the control group was significantly different (chi (2)= 9.389, P= 0.002). The frequencies of the 5A allele were 14.2% and 7.7% in the ACI patients group and the control group respectively (chi (2)= 9.430, P= 0.002). Serum level of MMP-3 in the ACI patients group was significantly higher than that in the control group (t= 24.867, P= 0.000). Among the ACI patients group, serum MMP-3 levels also had significant difference between the 5A/6A+ 5A/5A and the 6A/6A genotype (t= 2.057, P= 0.041).

CONCLUSIONThe present findings suggest that serum level of MMP-3 obviously increased within 48 hours of ischemic stroke and the genetic polymorphism of 5A/6A in the MMP-3 promoter is associated with ACI and MMP-3 expression in the Chinese Han population.

In this study we take a closer look at the diseases that afflicted Japanese police officers who were stationed in a remote mountainous region of Taiwan from 1921 to 1944. Samples were taken from the latrine at the Huabanuo police outpost, and analyzed for the eggs of intestinal parasites, using microscopy and ELISA. The eggs of Eurytrema sp., (possibly E. pancreaticum), whipworm and roundworm were shown to be present. True infection with Eurytrema would indicate that the policemen ate uncooked grasshoppers and crickets infected with the parasite. However, false parasitism might also occur if the policemen ate the uncooked intestines of infected cattle, and the Eurytrema eggs passed through the human intestines. These findings provide an insight into the diet and health of the Japanese colonists in Taiwan nearly a century ago.

Objective:To compare the application value of Caprini thrombosis risk assessment scale and Shanghai venous thrombosis risk factor scale in predicting venous thromboembolism in hospitalized maternal patients.Methods:This was a case-control study. A total of 67 pregnant women complicated with venous thromboembolism in the Obstetrics Department of Shandong Provincial Hospital Affiliated to Shandong First Medical University from January 2010 to September 2021 were retrospectively analyzed. And 144 pregnant women without venous thromboembolism in the same period were selected. Two venous thrombosis risk assessment tools were used to evaluate the pregnant women, and the predictive effectiveness and accuracy of the two assessment tools were compared.Results:The effects of the two risk assessment tools for venous thrombosis were different before and after delivery with statistical difference ( Z=8.15, 5.97, both P<0.01), but the Shanghai venous thrombosis risk factor scale (83.9%, 67.3%) was superior to Caprini thrombosis risk assessment scale (52.1%, 45.0%) in the accuracy of prenatal and postnatal prediction. The area under receiver operating characteristic curve showed that the Shanghai venous thrombosis risk factor rating scale (0.863) was significantly superior to the Caprini thrombosis risk assessment scale (0.748) after delivery. Conclusions:The Shanghai venous thrombosis risk factor scale is more valuable than the Caprini thrombosis risk assessment scale in the early risk identification of venous thromboembolism in pregnant women.

Objective To evaluate therapeutic effects of bone marrow mesenchymal stem cells(MSC)derived exosomes on alcohol-induced liver injury.Methods Eighteen male C57BL/6 mice aged 6 to 8 week were randomly divided into control group,model group and exosomes group,with 6 mice in each group.The mice in the model group and the exosomes group were fed with Lieber-DeCarli ad libitum diet(Dyets Inc.)for 4 weeks,followed by gavage a bolus of ethanol at day 26,27 and 28.The mice in the control group matched the alcohol-derived calories with dextran-maltose.Meanwhile,the mice in exosomes group were injected with MSC-exosomes via the tail vein at day 14 and 26.After the experiment,serum levels of alanine aminotransferase(ALT)and aspartate aminotransaminase(AST)were detected,and the pathological changes of liver tissues were observed.The expressions of nuclear factor erythroid 2-related factor 2(Nrf-2),heme oxygenase-1(HO-1),CD63,CD81,TSG101 and Cytochrome C were analyzed by Western blot,and mRNA levels of Nrf-2,HO-1,interleukin(IL)-10 and IL-17 were analyzed by real-time polymerase chain reaction(RT-PCR).The commercial kits were used to detect serum IL-10,IL-17 levels and liver tissue malondialdehyde(MDA),glutathione(GSH),superoxide dismutase(SOD)oxidative stress indicators.The numbers of regulatory T cell(Treg)and help T(Th)17 cells in the liver were analyzed by flow cytometry.One-way analysis of variance was used for comparison between groups.Results MSC-exosomes expressed positive markers CD63,CD81 and TSG101,but did not express the negative markers Cytochrome C.The serum ALT and AST levels in model group were(87.3±25.1)U/L and(223.2±43.5)U/L,respectively,while those in exosomes group were(47.7±12.0)U/L and(128.2±33.6)U/L,respectively.The differences between the two groups were both statistically significant(F=12.818 and 12.226,respectively,both P<0.05).Compared with control group,the SOD activity and GSH level in the model group significantly decreased with statistically significant differences(F=4.245 and 24.074,respectively,both P <0.05).Lieber-DeCarli ethanol feeding significantly increased intrahepatic MDA level in the model mice,which was reversed by MSC-exosomes supplementation,and the difference was statistically significant(F=36.675,P <0.05).Compared with control group,the intrahepatic protein expressions of Nrf-2 and HO-1 in model group were significantly decreased,while the expressions in exosomes group were obviously increased.The differences were statistically significant(F=33.623 and 14.960,respectively,both P <0.05).The expression trends of Nrf-2 and HO-1 mRNA were the same as those of protein expressions(F=20.784 and 276.336,respectively,both P <0.05).The proportions of liver Treg/Th17 in the control group,model group and exosomes group were 4.3±0.9,0.4±0.2,and 3.4±0.5,respectively.The differences among groups were statistically significant(F=64.227,P <0.05).Compared with control group,the serum protein and intrahepatic gene expression of IL-17 in the model group were significantly increased,which were reversed by MSC-exosomes treatment.The differences were statistically significant(F=15.581 and 40.095,respectively,both P<0.05).Serum IL-10 protein levels and intrahepatic IL-10 gene expression were significantly decreased after Lieber-DeCarli ethanol feeding,which were lower than the exosomes group.The differences were statistically significant(F=98.268 and 153.743,respectively,both P <0.05).Conclusions MSC-exosomes transplantation may relieve alcohol-induced liver injury.The mechanism could involve reduction of oxidative stress in the liver via regulating Nrf-2/HO-1 and normalizing the balance of Treg and Th17 cells.

Objective To examine the effect of adolescent intermittent ethanol exposure (AIE) on ethanol-induced conditioned place preference (CPP) and anxiety-like behavior in adolescent mice. Methods In experiment 1, adolescent male C57BL/6 mice at 4 weeks of age were randomly divided into AIE group and NS group (n=10 for each group). The binge drinking model was established by AIE (3 g/kg, 25%). The alcohol reward was evaluated using the ethanol-induced CPP paradigm (2 g/kg, 20%). In experiment 2, the anxiety-like behavior of adolescent male C57BL/6 mice were assessed using the elevated plus maze (EPM) test, and the animals were then allocated into high-anxiety mouse (HAM) and low-anxiety mouse (LAM) groups based on the percentage of open arm time (OT%). HAM and LAM were randomly divided into AIE group and NS group (n=8～10 for each group) with random number method, respectively. Then, anxiety-like behavior in four groups was measured again using the EPM test. Results In experiment 1. Ethanol preference (116.1± 12.9)s vs. (70.8±14.8)s, P=0.035) was significantly higher in AIE group relative to NS group. However, In experiment 2. The alteration in anxiety-like behaviors was not significant in either HAM-AIE or LAM-AIE groups (all P＞0.05). Conclusions AIE reinforces ethanol-induced CPP but does not affect the anxiety-like behavior in adolescent mice, suggesting that AIE may not play a role in anxiety-like behavior.
