Objective To study the reasons why PLoS One has set off an upsurge in China especially in hospitals, the academic level of papers published in PLoS One, and how to correctly judge the SCI-covered papers published by hospitals.Methods Papers published in PLoS One by hospitals in China were retrieved.The number of papers published in PLoS One by hospitals in China, the institutions that published the papers in PLoS One, and the num-ber of fund-supported papers were analyzed.Results A total of 9739 papers were published in PLoS One by hospitals in China from 2007 to October 2015, with an average cited frequency of 5.29.The majority of authors who published the papers were from affiliated hospitals of scientific research institutions and teaching hospitals of colleges and uni-versities.Of the 9739 papers, 87.78%were supported by funds from different foundations.Conclusion Nothing is strike about the academic level of papers published in PLoS One by hospitals in China with their average cited fre-quency lower than that (8.14) in our country.The SCI-covered papers published by hospitals should not be con-sidered as the only criterion in assessing the performances of staff in hospitals.

目的观察急性心肌梗死患者早期康复护理的远期效果。方法40例老年急性心肌梗死患者随机分为实验组20例(早期康复组)和对照组20例(常规治疗组),前者接受2周的康复护理,后者接受3周的康复护理。对两组患者进行为期18个月的随访,观察其心功能、活动情况,及心绞痛和再梗死的发生率。结果两组患者的心功能无明显差异,但实验组患者心绞痛的次数和再梗死的发生率低于对照组(P<0.05)。结论对急性心肌梗死患者进行早期康复是安全、可行的,可改善心功能和降低再梗死的发生率,减少并发症的发生。

Objective To investigate the distribution and the characteristics of drug resista-nce of coagulase negative Staphylococcus,and to provide the reference for properly choosi-ng antibiotic therapy of coagulase negative Staphylococcal infecs.Methods Contrasted 484 coagulase negative Staphylococcus(CNS) species isolated in hospital from 2001 to 2003 and 512 species from 2004 to 2007.Nosocomial CNS was identified and then drug resistance test was performed by K-B method,Nitrocefin method was utilized to detect β-lactamase.Clinical and Laboratory Standards Institute.Perfor-mance Standards forantimicro-bial susceptibility testing;Fifteenth information supplement.CLSI/NCCLS document M100-S17[J].Clinical and Laboratory Standards.Results The drug-resistant rate of.CNS to penicillin,erythromycin,oxacillin,amoxicillin/clavulanate,clindamycin,cepzolin,ceftriaxone and cefepime was high(>70%),whereas that to rifampin,nitrofurantoin,amikacin,tetracycline and trimetholvrim/sulfamethoxazole was low(<50%).No drug-resistant CNS strains to vancomyein were found.Conclusions,and no outstanding imparity from two groups.Conclusion The patterfi of resistance has changed greatly in the past 3 years.Clinical physicians should pay attention to properly choosing and using antibiotics.

Objective To investigate the role of allergen specific IgE in the child with recurrent auergic purpura,and to detect the relation between all kinds of allergen and the disease.Methods The serum specific IgE of allergen detected by ELISA in 100 cases of the child with recurrent auergic purpura.Results 81 cases of serum allergen-specific IgE were over than 50ku/L(81%).52 cases(52%)were positive reaction to more than two kinds of allergens and 29 cases(29%)were positive reaction to one kind of allergen.Several familiar aeroallergen mixed molds (19/100),dermatophagoides(12/100)and mugwort pollens(9/100).The most familiar food fish(28/100).shrimpand crab(22/100),milk(18/100).protein(11/100).Conclusion It suggests that aeroallergens,fish,shrimp and crab play an important role in the pathogenesis of repeating child anaphy lactic purpura.Mixed molds and protein foods are important pathogens to the disease.To detect the serum specific IgE could help screen allergens,and have important role to prevent disease.

Objective To evaluate the short-term efficacy and adverse effects of capecitabine as adjuvant chemotherapy of gastric cancer after resection in aged patients. Methods Sixty aged patients with gastric cancer (Ⅱ-Ⅲstage) after resection were randomized to two groups: the high dose group,in which 30 patients were treated least 6 therapeutic cycles (3 weeks for 1 cycle). Efficacy and adverse effects were assessed after 2 cycles. Results Two years' survival was 80% (24/30) in the high dose group and 77% (23/30) in the low dose group (χ2=0.54,P=0.45). The recurrence-free survival time was 19.2 months and 19.0 months respectively (χ2=0.82,P=0.36). Patients in the high dose group experienced more significant nausea/vomiting (Ⅰ-Ⅱ grade) than patients in the low dose group (χ2 = 9.82,P=0.02). However,there was no significant difference on grade Ⅲ-Ⅳ nausea/vomi-ting between the 2 groups(χ2=0.34,P=0.71). The incidence of grade Ⅰ-Ⅳ mucositis,hyperbilirubinemia and hand-foot syndrome (HFS) in the high dose group were higher than in the low dose group( P=0. 04,0. 02 and 0.04,respectively). There was no difference on weakness,lack of appetite and neutropenia between the two groups. in aged patients with similar efficacy and better tolerance of adverse effects compared to capeeitabine [2500 mg/

Objective To investigate the correlation between serum levels of folic acid and vitamin B12 and depression. Methods Thirty patients with depression were selected into depression group whose Hamilton de- pression scale score exceeded 17 and/or Hamilton anxiety scale score exceeded 14. Meanwhile, 30 subjects with- out clinically significant depression were selected into control group. Their serum levels of folic acid and vitamin B12 were determined. Zung Self-rating Depression Scale and Self-rating Anxiety Scale were used to evaluate the depression and anxiety. Results The serum levels of folic acid [ (4. 06±1. 61) vs. (6. 48±2. 36) ng/ml, P < 0. 05 ] and vitamin Bl 2 [ (427.96 126. 20) t . (498.46±119.08) pg/ml, P < 0. 05 ] were significantly lower in depression group than those in control group. No correlation was found between Hamilton depression score and serum folic acid level or vitamin B12 leveL Conclusion Patients with depression have lower serum folic acid and vitamin B12 levels than those of the healthy people.

Hepatic stellate cells(HSCs)are key sources of extraeellular matrix during liver fibrosis and in normal liver.During chronic injury,HSCs transform into myofibroblast-like cells,causing liver fibrosis.Hepatocellular carcinoma iS multiple factors disease.There are considerable HSCs infihration in the extracellular matrix of hepatocellular carcinoma.Investigation the interaction between HSCs and hepatocellular carcinoma Can provide a new thinking of hepatocellular carcinoma therapy.

MicroRNA (miRNA) is a kind of small non-protein coding RNA and can negatively regulate the expression of target genes at the transcriptional level. In tumors miRNA can act as oncogenes and tumor suppressor genes, and its deregulation in tumors may be a possible reason for tumor progression. Several studies have established the potential usefulness of miRNA as therapeutic targets for tumor metastasis.
