Objective To compare the efficacy and safety of naphthoquine, artemisinine and a combination of the two drugs in the treatment of faciparum malaria. Methods Of 230 patients, 100 patients were treated with combined regime (Co-NQ), 100 patients were treated with naphthoquine (NQ) and 30 patients were treated with artemisinine (QHS). All patients were hospitalized for 7 days and followed up for 28 days. Results The mean fever clearance time for Co-NQ, NQ, and QHS was (17.5 ?12.3)h, (32.7?17.7)h and (18.1?9.7)h respectively; the mean parasite clearance time was (30.0?8. 8)h,(45.5?10.0)h and (29.1?6.0)h respectively; and the 28 days cure rate was 97.0% ,100.0% and 66.7% respectively. Conclusion The Co-NQ possesses benefits of both naphthoquine and artemisinine, acting rapidly, with a short course of only one dose and a high cure rate. The regime is well tolerated by patients.

Objective To evaluate the efficacy of case management care practice on the self-care ability of the elderly patients with prostate cancer during the endocrine therapy. Methods About 84 patients were divided into two groups by drawing lots. About 41 cases in the control group continued their treatment after discharge and consulted the nurses or doctors by phone call in case of problems. The 43 cases in the observation group was treated with case management for 3 months. The self-care ability was compared between the groups before and after the intervention. Result After the intervention, the ESCA total score of the observation group, self-care skills, self protection responsibility and health knowledge level were significantly higher than that of the observation group before intervention and that of the control group (P<0.05). Conclusion Implementation of the case management can improve the self-care ability, health knowledge level, self-care skill and sense of responsibility of the elderly patients with prostate cancer during the endocrine therapy, eventually improving the patient's ability in self care.

Objective To study the antimalarial activity of naphthoquine phosphate combined with artemisinine against Plasmodium knowlesi in rhesus monkey.Methods Monkeys were randomly divided into 9 groups(3/group).The monkeys in groups A and B were treated i.g.once daily for 3 days with 6 or 10 mg/kg of naphthoquine phosphate respectively.Those in groups C and D were treated i.g.twice for the 1st day and once for the 2nd and 3rd day with 31.6 or 100 mg/kg of artemisinine respectively.In groups E, F and G, they were treated i.g.only once with the combination of naphthoquine phosphate 10 mg/kg and artemisinine 10, 20 or 25 mg/kg respectively.Groups H and I served as controls which were treated i.g.only once with 10 mg/kg of naphthoquine phosphate and 30 mg/kg of artemisinine respectively.Parasitemia was examined beginning 24 h after drug administration.The observation lasted 105 days when no more parasite was found.Results At 24 h after drug administration, the parasite reduction rate in all groups was higher than 90%.The parasite clearance time for groups E, F and G was(56.0?16.0),(53.3?4.6), and(56.0?8.0) h respectively, more rapid than that of Group H(69.3?4.6) h.There were 1, 3, 3, 2, 2, and 3 monkeys in groups A, B, D, E, F, and G respectively which were cured.No monkeys were cured in groups C, H and I.Conclusion The combination of naphthoquine phosphate and artemisinine is superior to the single component and the optimum proportion in the combination is 1:2.5 in treating P.knowlesi infection in monkeys.

ObjectiveTo clarify the characteristics and clinical signiifcance of the NOTCH1 mutations in childhood T-cell acute lymphoblastic leukemia (T-ALL).MethodsAmplify and sequence the heterodimerization (HD) domain and the pro-line-glutamicacid-serine-threonine (PEST) domain of theNOTCH1 gene in 28 T-ALL children, in order to explore the frequency, position and type of the mutations as well as their reletions with prognosis.ResultsIn 28 children with T-ALL, 15 cases (51.57%) had been identiifed theNOTCH1 mutations, all of which were heterozygous mutations. The lymphoblast counts in peripher-al blood and bone marrow in theNOTCH1 mutant group at admission were signiifcantly higher than in the non-mutant group (P<0.05). The 1-year remission rate in the 28 children with T-ALL was 75% (21/28), including 80% (12/15) in mutant group in which 3 patients relapsed and all of them died (1-year mortality 20%) and 69.20% (9/13) in non-mutant group in which 4 patients relapsed but all survived (1-year mortality 0%).ConclusionsThe children with T-ALL had a high incidence of NOTCH1 mu-tations at various sites. In addition, the patients withNOTCH1 mutations had more severe disease at diagnosis, better short-term prognosis and poor outcome with salvage therapy after relapse.

Objectives To investigate the correlation between single nucleotide polymorphisms (SNP) in interleu-kin-15 (IL-15) and treatment response in childhood acute lymphoblastic leukemia (ALL). Methods Genomic DNA samples extracted from remission bone marrow cells of ALL patients were genotyped by MassArray. Five SNPs (rs10519612, rs10519613, rs17007695, rs17015014 and rs35964658) in IL-15 and their association to minimal residual disease (MRD) status in the end of induction therapy were studied. Results SNP rs17007695 was associated with the early response in children with ALL(P=0.049) and the incidence of positive MRD after induction therapy in CC genotype carriers was 1.8 times more than that in TT genotype carriers. Haplotype analysis of these five SNPs showed that the frequency of haplotype CACGG in MRD positive group was 2.1 times higher than that in MRD negative group (P=0.035). Conclusions IL-15 gene polymorphism was associated with the early treatment response in Han Chinese children with acute lymphoblastic leuke-mia.

OBJECTIVETo assess the relationship between nodular goiter and hepatitis C virus infection.

METHODSNinety-seven cases of early treatment in patients with chronic hepatitis C were collected for analysis.Data on patient age,sex,hepatitis duration and other general information were collected.In addition, data on clinical measures of thyroid function (including T3, t4, tSH) and thyroid autoantibodies (thyroid peroxidase antibody TPO-Ab, thyroglobulin antibody Tg-Ab), as well as findings from thyroid dimensional ultrasonography were collected. One hundred and eleven cases of early treatment in patients with chronic hepatitis B and 106 eases of females 40 years old or older with high risk of nodular goiter were collected for use as controls.The relationship between nodular goiter with thyroid function, thyroid autoantibodies levels,sex,age,and hepatitis C virus infection were statistically analyzed.

RESULTSThe prevalence rates of nodular goiter in the chronic hepatitis C group, the chronic hepatitis B group and the more than or equal to 40 year-old women with high risk of nodular goiter were 53.6%,36.9% and 59.4% respectively.The prevalence rates of nodular goiter in the chronic hepatitis C group and the more than or equal to 40 year-old women with high risk of nodular goiter were significantly higber than that in the chronic hepatitis B group (x² values: 5.820 and 10.996, P < 0.05). The average age of patients with chronic hepatitis C combined with nodular goiter was significantly higher than their counterparts without goiter (F=6.408, P < 0.05),and the prevalence rate in the more than or equal to 40 year-old women with high risk of nodular goiter was significantly higher than that of their counterparts who were less than 40 years-old (60.0% vs. 23.5%; x² =7.499, P less than 0.05). The prevalence of nodular goiter in patients with chronic hepatitis C was significantly greater for females than for males (62.1% vs. 41.0%; x 2 =4.152, P < 0.05).The prevalence of nodular goiter in patients with chronic hepatitis C was also significantly higher for females more than or equal to 40 years old than for males (70.2%, 33/47 vs. 45.5%,15/33; x² = 4.952, P < 0.05).The duration of hepatitis, thyroid function and thyroid autoantibodies were similar between the patients in the chronic hepatitis C group with or without nodular goiter.

CONCLUSIONSThe patients with chronic hepatitis C had a higher prevalence of nodular goiter,with an average of up to 53.6%, than the patients with chronic hepatitis B,and the women the more than or equal to 40 years old had even higher prevalence, at 70.2%, suggesting that patients with chronic hepatitis C should be routinely examined by thyroid ultrasound. Thyroid function and thyroid autoantibodies were not correlated with prevalence of goiter among the chronic hepatitis C patients.

Objective:To investigate the depersonalization status and to analyze the effect of workplace incivility perception, intrusive rumination and fear of negative evaluation on depersonalization in clinical nurses.Methods:In May 2019, 10 cities were selected as sampling cities by the method of grabbing random ball in Henan Province and Fujian Province. Using the stratified sampling, clinical nurses were selected as the research objects for a questionnaire survey in 22 tertiary hospitals and 23 secondary hospitals, included 1200 nurses. A total of 1200 questionnaires were issued and collected, and 1159 valid questionnaires were collected with effective recovery of 96.6%. Clinical nurses were investigated by Workplace Incivility Scale, Event Related Rumination Inventory, Fear of Negative Evaluation Scale, Maslach Burnout Inventory-General Survey. The demographic characteristics of nurses' depersonalization were compared and analyzed with t test and single factor analysis of variance. The influence mechanism of workplace incivility perception, intrusive rumination and fear of negative evaluation on depersonalization was analyzed with Bootstrap. Results:Depersonalization scores were (9.3±2.6) points, 467 of those had depersonalization symptoms in clinical nurses (40.3%). The scores of depersonalization of those with <3 years of service [ (10.5±2.9) points] was higher than those with 3-10 years [ (9.1±2.8) points] and 11-31 years [ (9.0±2.9) points]. The scores of depersonalization of those with monthly earning of <3000 yuan [ (10.1±2.8) points] was higher than those with 3000-7999 yuan [ (8.4±2.7) points] and 8000-12000 yuan [ (8.0±2.9) points]. The scores of depersonalization of clinical nurses in surgical departments [ (10.0±2.9) points] was higher than those in non-surgical departments [ (8.7±2.6) points]. The scores of depersonalization of clinical nurses in tertiary hospitals [ (10.0±2.7) points] was higher than those in secondary hospitals [ (8.6±2.8) points]. The differences were statistically significant ( P<0.05). Workplace incivility perception affected depersonalization through the single mediating role of intrusive rumination, fear of negative evaluation and the chain mediating role of intrusive rumination and fear of negative evaluation ( β=0.16, 0.17, 0.07, 95% CI: 0.15-0.20, 0.15-0.21, 0.03-0.09, P<0.05) . Conclusion:Workplace incivility perception directly or through the independent mediating effects of intrusive rumination or fear of negative evaluation, and the chain mediating effects of intrusive rumination and fear of negative evaluation influences the depersonalization of clinical nurses.

The rapid worldwide rise in obesity rates over the past few decades imposes an urgent need to develop effective strategies for treating obesity and associated metabolic complications.Bariatric surgical pro-cedures,such as Roux-en-Y gastric bypass(RYGB)and vertical sleeve gastrectomy(VSG),currently provide the most effective treatment for obesity and type 2 diabetes(T2D),as well as for non-alcoholic steatohepatitis(NASH).However,the underlying mechanisms of the beneficial effects of bariatric surgery remain elusive.Recent studies have identified bile acids as potential signaling molecules involved in the beneficial effects of bariatric surgery.This review focuses on the most recent studies on the roles of bile acids and bile acid receptors Farnesoid X receptor(FXR)and G protein-coupled bile acid receptor 5(TGR5)in bariatric surgery.We also discuss the possibility of modulating bile acid signaling as a phar-macological therapeutic approach to treating obesity and its associated metabolic complications.
