Objective It is to study the influence of atorvatatin on serum C-reactive protein(CRP)level in acute cer- ebral infarction patients and to analyze its clinical significance.Methods 62 patients with acute cerebral infarction di- agnosed by CT or MRI were chosen and divided into two groups randomly.Both the groups were treated with normal method and the treatment group was given atorvastatin 20mg per day.Serum CRP levels in the two groups were measured by immunnturbidimetry within24h after final diagnosis and at two weeks the level decreased obviously in treatment.Re- slllts Serum CRP levels all increased in the patients.After treatment for two weeks the level decreased obviously in treatment group.The difference was significant compared with control group.Conclusion Atorvastatin can markedly reduce the serum CRP level in acute cerebral infarction patients and has important significance for the pathogenetic condi- tion change and prognosis of cerebral infarction.

diagnosing of primary hepatocelluar carcinoma , but GP73 combined with AFP detection can significantly improve the diagnostic accuracy , and some primary hepatocelluar carcinoma cases with AFP negative can be avoided missing efficiently by parallel diagnostic test.

Objective To explore the effect of sequential therapy of transcatheter arterial chemoembolization (TACE) followed by percutaneous microwave coagulation therapy (PMCT) in treating early-stage primary hepatocellular carcinoma (PHC), and to analyze the factors that may affect the prognosis. Methods During the period from Jan. 2011 to Apr. 2014, a total of 66 patients with early-stage PHC were admitted to authors’ hospital. TACE was carried out in all patients, which was followed by PMCT in 5 -7 days. All patients were followed up regularly. CT, MR, ultrasonography, AFP, liver function and other related laboratory tests were performed. Kaplan-Meier estimation was used for the analysis of disease-free survival time. The high-risk factors were analyzed by Chi-square test. Multivariate analysis was conducted by using logistic analysis method. Results After TACE the serum levels of ALT, TBIL and DBIL were increased significantly when compared with preoperative ones (P< 0.01). After sequential PMCT the serum levels of AST, ALT and DBIL were increased significantly when compared with preoperative ones (P< 0.01). When compared with TACE, after sequential PMCT the serum level of AST was increased (P< 0.01), while serum levels of TBIL and DBIL were decreased (P< 0.01). Compared with TACE and preoperative data, the post-PMCT AFP level was decreased (P < 0.01). During the follow-up period one patient died. The 3-year cumulative survival rate was 98.5%. Recurrence was seen in 19 cases. The one-year, 2-year and 3-year disease-free cumulative survival rate was 70.3%, 50.8% and 41.6% respectively. Univariate and multivariate analysis indicated that the risk factors of recurrence in early-stage PHC included AFP ≥ 100 μg/L, viral load≥103 copies/ml and irregularity of tumor border (P<0.05). Conclusion Sequential therapy of TACE followed by PMCT is an ideal treatment for early-stage PHC, sequential PMCT after TACE does not affect liver recovery process. AFP ≥ 100 μg/L, viral load ≥ 103 copies/ml and irregularity of tumor border are the risk factors of recurrence.

Objective To investigate the prognostic factors affecting the outcome of patients with intermediate-advanced hepatocellular carcinoma (HCC) receiving transcatheter arterial chemoembolization (TACE) combined with percutaneous microwave ablation (MWA). Methods During the period from January 2011 to July 2012 at authors’ hospital, a total of 64 patients with intermediate-advanced HCC were treated with TACE together with MWA. Fourteen potential variables which might affect the prognosis were colleted and were retrospectively analyzed. Kaplan-Meier model and log-rank test were used for single factor analysis, while Cox regression model was used for multiple factor analysis. Results The one-year, 1.5-year and 2-year overall survival rates were 75.8%, 48.4% and 33.9%, respectively. Single factor analysis and Cox regression analysis indicated that six factors, i.e. tumor size, number of tumors, portal vein tumor thrombus, serum α-fetoprotein level, tumor staging and oral administration of sorafenib, bore a relationship to the prognosis. Conclusion The tumor size, number of tumors, portal vein tumor thrombus, serum α-fetoprotein level and tumor staging are risk factors influencing the results of interventional comprehensive therapy , while oral administration of sorafenib is a protective factor for the prognosis.

OBJECTIVE:To explore and analyze signals of Xiyanping injection-induced urticaria from spontaneous reporting system database of Jiangxi province. METHODS:The continuous ADR report monitoring data were collected from spontaneous re-porting system of Jiangxi province,and established database. Bayesian confidence propagation neural network(BCPNN) method was used to calculate information component,IC value of Xiyanping injection-induced urticaria. The year-to-year changes of IC val-ue and its interval were analyzed. RESULTS:A total of 328324 ADR reports were collected in Jiangxi province during 2004-2016. The IC value of Xiyanping injection-induced urticaria detected by BCPNN method was 1.10(the lower limit of IC value was 0.65, and upper limit was 1.54),i.e. there was signal and the IC value ranged from-0.87 to 1.65. CONCLUSIONS:The results of BCPNN method suggest that urticaria is a warning signal of Xiyanping injection. The risk is increasing gradually,and prediction precision increase with the addition of report quantity.

Objective:To investigate the clinical characteristics and prognosis of cytomegalovirus (CMV) reactivation in patients with liver failure.Methods:A total of 75 patients diagnosed with liver failure and tested for serum CMV DNA between January 2016 and June 2019 in Huashan Hospital, Fudan University were retrospectively analyzed. According to the CMV DNA test results, the patients were divided into CMV DNA positive group and CMV DNA negative group. The classification of liver failure, the use of glucocorticoids, the proportions of T lymphocyte subsets of the two groups were compared and the prognosis was evaluated. Mann-Whitney U test and chi-square test were used to analyze the data. Results:Of the 75 patients with liver failure, 17 were CMV DNA positive and 58 were CMV DNA negative. Among the 17 CMV DNA positive patients, nine were acute (subacute) liver failure, and 13 were treated with glucocorticoids, which were all significantly higher than those in the CMV negative group (20.7%(12/58) and 20.7%(12/58), respectively). The differences were both statistically significant ( χ2=6.70 and 18.40, respectively, both P<0.05). The proportions of CD3 + T lymphocytes and CD8 + T lymphocytes in the CMV DNA positive group were both higher than those in the CMV DNA negative group, and the proportions of CD4 + T lymphocytes, the ratio of CD4 + /CD8 + T lymphocytes and the proportion of B lymphocytes were all lower than those in the CMV DNA negative group. The differences were all statistically significant ( U=274.50, 165.50, 273.00, 185.00 and 189.00, respectively, all P<0.05). Acute (subacute) liver failure (odds ratio ( OR)=4.3, 95% confidence interval ( CI) 1.3-12.6) and glucocorticoid use ( OR=12.5, 95% CI 3.4-38.3) were risk factors for CMV reactivation in patients with liver failure. The disease improvement rate in the CMV DNA negative group was 56.9% (33/58), and five out of 17 patients improved in the CMV DNA positive group, with a statistically significant difference ( χ2=1.99, P=0.04). Conclusions:The use of glucocorticoids increases the risk of CMV reactivation in patients with liver failure, and CMV reactivation in patients with liver failure presents immune disorders which seriously affect their prognosis. Therefore, it is important to pay attention to CMV DNA monitoring in patients with liver failure using glucocorticoids.

OBJECTIVE:To investigate general regularity and characteristics of tetanus antitoxin (TAT) induced by ADRs,in order to provide reference for rational drug use in the clinic.METHODS:Domestic and foreign literatures on ADRs induced by TAT were retrieved,and related information of 2 636 case of ADR were analyzed statistically.RESULTS:Among patients whose gender and age were recorded,male with ADR induced by TAT was more than female,mainly aged 15-35 years old,accounting for 70.32 ％ (289/411);28.28 ％ (56/198) used water for injection;ADR occurred within 30 min after medication in 5.84％ (154/2 636)cases;main ADR were lesion of skin and its appendents,circulatory system damage,systemic reaction damage.Main clinical manifestations were urticaria,rash,chest tightness and anaphylaetic shock,etc.Ten cases died and 7 cases had sequelae;the rest were all recovered and cured after symptomatic treatment.CONCLUSIONS:TAT has a higher proportion of allergic reactions,especially anaphylactic shock,but great importance should be attached to rare auditory and vestibular dysfunction,visual impairment,elevated white blood cell count and other ADR.It is suggested to strengthen medication monitoring and used drugs strictly in accordance with drug package inserts so as to promote rational drug use.

OBJECTIVETo investigate the activity of ChE in rats poisoned by dimehypo and then treated with pralidoxime methylchloride or unithiol.

METHODRats were divided into control group (dimehypo); intervention groups [dimehypo plus pralidoxime methylchloride or dimehypo plus unithiol (sodium dimercaptopropanesulphonate)]. Rats were dosed with 4 different doses of dimehypo: 1/16, 1/8, 1/4 and 1/2 of LD50 respectively(the LD50 of dimehypo is 342 mg/kg). After being poisoned with dimehypo orally, rats were immediately injected intramuscularly with pralidoxime methylchloride or unithiol. The activity of ChE in blood was detected before and 1/2, 1, 2, 4 and 24 h after poisoning in dimehypo and intervention groups.

RESULTThe ChE activity of four dose subgroups at 1 h after poisoning were (1.04 +/- 0.21), (0.84 +/- 0.12), (0.71 +/- 0.12), (0.66 +/- 0.07) U/ml respectively; the ChE activity of pralidoxime methylchloride intervention groups were (1.01 +/- 0.18), (1.17 +/- 0.11), (1.01 +/- 0.04), (1.03 +/- 0.12) U/ml respectively; and the ChE activity of unithiol intervention groups were (1.15 +/- 0.15), (1.26 +/- 0.27), (1.08 +/- 0.08), (1.04 +/- 0.12) U/ml respectively. The inhibited ChE in blood was recovered by either treatment with pyraldoxime methylchloride or unithiol. These two drugs had similar effects of recovering the activity of ChE(P > 0.05), but at higher doses(1/4 and 1/2 of LD50) the effects of both were not so good.

CONCLUSIONPralidoxime methylchloride and unithiol could partly recover the activity of ChE inhibited by dimehypo.

OBJECTIVETo determine whether and to what degree the activity of cholinesterase(ChE) is inhibited by dimehypo at different doses of dimehypo [scientific name: 2-dimethylamine-1,3-bi(sodium hyposulfit)].

METHODRats were dosed with dimehypo or methamidophos orally, and were randomly divided into four subgroups according to the pesticide doses, which were 1/16, 1/8, 1/4 and 1/2 of LD50 respectively(the LD50 of dimethypo and methamidophos is 342 mg/kg and 20 mg/kg respectively). The activity of ChE in blood was determined before and 30 min, 1, 2, 4 and 24 h after exposure. The modified Ellman Method was employed to measure the activity of ChE.

RESULT1/16 LD50 dose of dimehypo did not affect the activity of ChE. When the dose increased, the activity of ChE decreased accordingly. 1/2 LD50 dose of dimehypo inhibited the activity of ChE by 35.9% compared with that of control group(P < 0.01). In rats dosed with methamidophos, even 1/16 LD50 dose inhibited the activity of ChE by 42.4% compared with that of control group. When the dose of methamidophos increased, the activity of ChE decreased accordingly. 1/2 LD50 dose of methamidophos inhibited the activity of ChE by 52.9%. The activity of ChE in the rats dosed with dimehypo at various doses was significantly lower than that in the rats dosed with corresponding doses of methamidophos(P < 0.01).

CONCLUSIONHigher doses of dimehypo may inhibit the activity of ChE. However, as compared with methamidophos, dimehypo is a weaker inhibitor of ChE.
