RESUMEN
Objective:To construct an evaluation index system for comprehensive budget management at public hospitals and conduct empirical research for reference in evaluation of comprehensive budget management at public hospitals.Methods:From May to June 2022, based on the Implementation Measures for the Comprehensive Budget Management System of Public Hospitals and its interpretations, literature analysis, and expert interviews, a preliminary evaluation index system was developed for comprehensive budget management of public hospitals. Then the Delphi method was applied for two rounds of expert consultation, with experts invited to evaluate the importance of indexes, while the analytic hierarchy process was used to calculate the weight values of indexes. Based on such a comprehensive budget management evaluation index system, a questionnaire was developed, and tertiary public hospitals were selected based on the principle of convenient sampling. Then a questionnaire survey was conducted from June to October 2022. The questionnaire was filled out by hospital level leaders(chief accountants), finance/audit leaders, and directors of finance/audit/operation management departments from the sample hospitals with professional knowledge and rich operational management experience in budget management. The comprehensive budget management level of the sample hospital was thus evaluated based on the survey results. Results:The comprehensive budget management evaluation index system for public hospitals was composed of 2 first-level indexes, 4 second-level indexes, and 20 third-level ones. The weights for the 2 first-level indexes of target building and management orientation were both 0.500, while the weights for the 4 second-level indexes, namely strategic implementation, comprehensive coverage, performance evaluation, and adaptation matching were all 0.250. Among the third-level indexes, the weights of budget execution, system improvement, system establishment, organizational construction, and revenue and expenditure business ranked top five, with weights of 0.070, 0.069, 0.066, 0.066, and 0.064, respectively. A total of 95 hospitals were selected for questionnaire survey, and the evaluation found 46 of them with a comprehensive budget management level of " excellent" and " good" , 27 with a " moderate" level, and 22 with a " poor" and " very poor" level. Scores of the third-level indexes were between 39-94 points, while the score of 6 third-level indexes were below 60 points, namely interconnection, budget analysis, compatibility and adaptation, system improvement, participation level, and assessment application.Conclusions:The evaluation index system for comprehensive budget management at public hospitals in this study proves rational and practical, serving as a reference for the evaluation of comprehensive budget management at public hospitals and related researches.

Conclusion ApoE gene polymorphism was associated with the morbidity of patients with aMCI，and ApoEε4 may be a risk factor for aMCI. The thalamus,posterior cingulate cortex were also involved.Gray matter atrophy in patients with aMCI was mainly located in the parietal lobule and the insular.
RESUMEN
OBJECTIVE：To investigate the occurrence of medication errors （ME）in patients with hyperuricemia/gout and its related factors ，in order to avoid and reduce the occurrence of related ADE and ensure the safety of drug use in patients. METHODS：The ME reports related to hyperuricemia/gout were collected from National Monitoring Network for Clinical Safe Drug Use during Sept. 22nd，2012 to Jul. 9th，2020，and then analyzed in terms of reporting provinces ，classification and drugs involved，error content ，initiator and error factors. RESULTS ：A total of 179 ME reports ，which met inclusion criteria ，were included from 47 hospitals in 11 provinces. The drugs involved mainly included benbromarone （36 cases，20.11％），allopurinol （31 cases，17.32％），calcium carbonate D 3（30 cases，16.76％），inverting sugar electrolyte （24 cases，13.41％）and sodium bicarbonate（22 cases，12.29％）. Grade B ME were the most frequently reported （124 cases，69.27％）；severe ME occurred in 3 cases（1.68％）. The main errors were contraindications ，accounting for 70 cases（37.43％，mainly involving calcium carbonate D 3 and inverting sugar electrolyte ）. The people who caused ME were mainly doctors ，involving 126 cases（70.39％，the main content of errors was contraindications ）. The main error factors for ME were personnel factors ，involving 120 cases（67.04％，mainly lacking of knowledge ），followed by environmental factors （33 cases，mainly equipment failure ）. CONCLUSIONS ：ME in patients with hyperuricemia/gout are mainly caused by uric acid-lowering drugs and non-uric acid-lowering drugs that cause changes in uric acid. The main error contents include contraindications ，which were mostly caused by non-uric acid-lowering drugs and doctors. The main error factors are lack of knowledge and equipment failure. It is suggested to strengthen personnel training or introduce clinical medication support decision-making system ，while pay attention to the correct use and maintenance of related equipment in the process of drug use.
RESUMEN
@#Objective In order to improve the clinicians’ awareness of stroke mimics and to avoid inappropriate therapy，we described the clinical data of 3 patients with stroke mimics and reviewed the literature.Methods We retrospectively gave a description of the medical history，clinical manifestations，imaging data and treatments of three typical cases of stroke mimics from January 2017 to September 2018 in our hospital.Results Case1 The patient complained of inability to speak in the morning and weakness of the right limbs for several hours. Head CT showed old lacunar infarctions.The primary diagnosis was acute ischemic stroke（AIS）. The patient developed with fever and seizures during the following days. The diagnosis of intracranial subdural empyema was confirmed by head MRI and further surgery was performed. The reason why we didn’t make the right diagnosis was that the resident didn’t ask the medical history in detail and we didn’t check the head MRI in time.Case 2 We describe a 70-year-old man who presented to our emergency department（ED）with acute onset of left arm soreness and left leg weakness for 5 hours. The AIS was considered. The patient was admitted to the ward and we knew his first symptom was back pain which lasted about few minutes. Spinal cord MRI revealed spinal epidural hematoma. Acute spinal epidural hematoma rarely presents with unilateral weakness of the limbs，mimicking a stroke. Because inappropriate thrombolysis can lead to devastating symptoms，spinal epidural hematoma should be excluded when evaluating an acute stroke patient with a symptom of pain who is a possible candidate for thrombolytic therapy. Case3 The patient admitted to the ward with a seizure，speech disorder and right limbs paralysis for more than 20 hours. The patient’s head MR angiography showed severe stenosis of the left middle cerebral artery. The diagnosis of AIS was made. But the two head MRI being negative for acute ischemic lesion and three dimensional arterial spin-labeled brain perfusion MRI was normal. The diagnosis of AIS was wavering. Within 5 days from the admission，there was almost a complete remission of the neurological findings. The electroencephalogram examination revealed focal abnormalities and Todd’s paralysis was finally confirmed. The neurological deficits during the postictal seizure phase are usually short lasting，but they may last up to days after the convulsion.Conclusion Stroke mimics term is applied in a clinical evaluation，describing those non-vascular conditions that simulate stroke，namely those presenting with an acute neurological deficit.Careful clinical assessment （clinical history and neurological examination）in association with laboratory evaluation is important for depicting the stroke mimics. Brain imaging is essential for the correct diagnosis of AIS and stroke mimic exclusion. With the use of the clinical，laboratory data and magnetic resonance imaging （MRI） evaluation，the misdiagnosis incidence of stroke mimics will decline to lower degree.
RESUMEN
Objective:To investigate the role of type Ⅵ secretion system (T6SS) in the pathogenicity and antibiotic resistance of Acinetobacter baumanii. Methods:From January 1 to December 31, 2016, a total of 45 Acinetobacter baumanii isolates were collected from patients with bloodstream infection in the First Affiliated Hospital of Wenzhou Medical University. The susceptibilities to commonly used antimicrobial agents were determined by VITEK 2 Compact automatic microbiology analyzer. Detection of T6SS characteristic gene hemolysin coregulated protein ( hcp) was achieved by polymerase chain reaction. Biofilm formations, serum resistances and competition tests of T6SS-positive/negative Acinetobacter baumanii were performed in vitro. The clinical data of patients with bloodstream infection were collected and analyzed. Chi-square test, t test and Kruskal-Wallis test were conducted for statistical analysis. Results:The positive rate of T6SS in 45 Acinetobacter baumanii isolates was 53.3% (24/45). The resistance rates of T6SS-positive Acinetobacter baumanii to ceftazidime, ciprofloxdcin, gentamicin, imipenem, levofloxacin, piperacillin/tazobactam, tobramycin and cefepime (95.8%, 95.8%, 66.7%, 95.8%, 79.2%, 95.8%, 79.2%, 91.7%)were all higher than that of T6SS-negative Acinetobacter baumanii (28.6%, 28.6%, 28.6%, 28.6%, 9.5%, 23.8%, 23.8%, 28.6%), and the differences were all statistically significant ( χ2=22.12, 22.12, 6.51, 22.12, 21.83, 24.72, 13.79, 18.97, respectively, all P<0.05). The biofilm formation ability, serum resistance and competitive ability of T6SS-positive Acinetobacter baumanii were stronger than those of T6SS-negative Acinetobacter baumanii, and the differences were all statistically significant ( t=4.99, Z=-2.61 and -2.27, respectively, all P<0.05). The positive rate of T6SS isolated from intensive care unit (ICU) ward (80.0%, 16/20) was significantly higher than that from non-ICU ward (32.0%, 8/25; χ2=10.29, P<0.05). But T6SS had no effect on the prognosis of patients ( χ2=1.74, P=0.188). Conclusions:T6SS of Acinetobacter baumanii is associated with high pathogenicity, and the high drug resistance rate makes treatment extremely difficult. Physicians need to pay much attention, especially to the patients from ICU wards.
RESUMEN
Objective To investigate the chlorhexidine acetate-resistance in Klebsiella pneumoniae ( K. pneumoniae) clinical isolates and to analyze the possible mechanisms and molecular epidemiology of re-sistant isolates. Methods A total of 332 K. pneumoniae clinical isolates were collected in the First Affilia-ted Hospital of Wenzhou Medical University in 2015. Standard agar dilution was used to screen chlorhexidine acetate-resistant isolates. The minimum inhibition concentrations ( MIC) of chlorhexidine acetate to resistant isolates with and without the presence of carbonyl cyanide m-chlorophenyl hydrazone ( CCCP) , which was an efflux pump inhibitor, were analyzed. Efflux pump genes of cepA, qacE and qacΔE1 that carried by and ex-pressed in those isolates were detected by polymerase chain reaction ( PCR) and quantitative real-time PCR ( RT-qPCR) , respectively. The biofilm formation ability was measured by crystal violet staining. The homol-ogy among the chlorhexidine acetate-resistant isolates was investigated with multilocus sequence typing ( MLST) and pulsed-field gel electrophoresis ( PFGE) . Results Twenty-five K. pneumoniae strains were re-sistant to chlorhexidine acetate. The MIC values of chlorhexidine acetate for them were reduced by at least four-fold in the presence of CCCP. Strains carrying the genes of cepA, qacE and qacΔE1 accounted for 100％, 40％ and 40％, respectively. The expression of the efflux pump genes in the chlorhexidine acetate-resistant isolates was higher than that in the susceptible isolates. The biofilm formation ability of the chlo-rhexidine acetate-resistant isolates was better than that of the susceptible isolates. Furthermore, negative, weak-positive and positive biofilm formation ability was observed in four ( 16％) , 20 ( 80％) and one (4％) strains, respectively. The results of MLST and PFGE showed that the 25 chlorhexidine acetate-resist-ant isolates belonged to 19 different sequence types ( ST) with diverse PFGE patterns. Conclusions This study suggested that active efflux was the main mechanism of chlorhexidine acetate resistance in K. pneumoni-ae. The 25 chlorhexidine acetate-resistant K. pneumoniae strains possessed different biofilm formation ability and shared low homology.

Objective This study aims to investigate the sex difference in the hippocampus and parahippocampus in patients with bipolar disorder. Methods We acquired T1－weighted structural MRI from 133 bipolar type I patients (60 males) and 144 normal controls (81 males). The General Linear Model was used to examine the relationship between sex and brain volumes of the hippocampus and parahippocampus, with age and intracranial volume as covariates. Results Patients showed significantly smaller volumes of the bilateral hippocampus and parahippocampus (P＜0.01). There were sex－by－diagnosis interactions in the left parahippocampus gyrus (F=6.534, P=0.044). Male patients had significant smaller volumes of the left parahippocampus gyrus compared to the male normal controls (P＜0.001) whereas the volumes were not significantly different between female patients and female normal controls (P＞0.05). Conclusion The results suggest sex difference in the left parahippocampus gyrus volume in patients with bipolar type I disorder, which deserves further investigation in the future bipolar imaging researches.

Objective To investigate the in vitro antibacterial activity of triclosan combined with different antibacterial agents against triclosan-resistant multidrug-resistant Acinetobacter baumannii ( A. bau-mannii) . Methods A total of 626 A. baumannii strains were collected from the First Affiliated Hospital of Wenzhou Medical University from 2016 to 2017. The sensitivity of these A. baumannii strains to common an-tibiotics was detected by VITEK 2-compact automatical microbiological analyzer and the minimum inhibitory concentrations ( MIC) of triclosan were detected by agar dilution method. Checkerboard method was used to detect the changes in MIC values of triclosan against 16 triclosan-resistant multidrug-resistant A. baumannii strains after it was used in combination with four external ointments, including gentamicin, erythromycin, chloramphenicol and kanamycin, and three common antibiotics of imipenem, meropenem and ciprofloxacin, respectively. Fractional inhibitory concentration index ( FICI) was used to evaluate the joint bacteriostatic effects. Results Among the 626 A. baumannii strains, 17 were resistant to triclosan with a drug resistance rate of 2. 7％ (17/626). These triclosan-resistant strains had high MIC values for ciprofloxacin, imipenem,ceftazidime and other commonly used clinical antibiotic and most of them were multidrug-resistant. After tri-closan was used in combination with seven different antibacterial drugs, the MIC values of all drugs de-creased to various degrees compared with those when they were used alone. Triclosan in combination with gentamicin, chloramphenicol and ciprofloxacin showed synergistic effects on 62. 5％, 56. 25％ and 62. 5％of the 16 strains and additive effects on 37. 5％, 43. 75％ and 37. 5％, respectively. When it was used in combination with erythromycin, kanamycin, imipenem and meropenem, synergistic effects on 37. 5％, 25％, 12. 5％ and 12. 5％, additive effects on 37. 5％, 56. 25％, 62. 5％ and 62. 5％, and indifferent effects on 25％, 18. 75％, 25％ and 25％ of the strains were detected, respectively. No antagonistic effect was found between triclosan and any of the above antibiotics. Conclusions Triclosan combined with genta-micin, chloramphenicol and ciprofloxacin had better in vitro antibacterial effects against the triclosan-resist-ant multidrug-resistant A. baumannii strains in this study with synergistic and additive effects. Some indiffer-ent effects were found between triclosan and kanamycin, erythromycin, imipenem and meropenem, but no antagonistic effects were detected.

RESUMEN
Objective@#To investigate the association between alcohol use and incidence of type 2 diabetes mellitus (T2DM) in the middle-aged and elderly male population.@*Methods@#All participants were from Dongfeng-Tongji cohort, 27 009 retired employees from Dongfeng Motor Corporation in Hubei Province were enrolled in the Dongfeng-Tongji cohort baseline survey in 2008. In baseline study, information of alcohol use and other covariates were collected by semi-structured questionnaire and all participants completed physical examination including the test of fasting glucose and blood lipid levels. A total of 6 784 male participants from Dongfeng-Tongji cohort who were without diagnosis of diabetes, coronary heart disease, stroke, or cancer in baseline study were enrolled in this study. We completed the first follow-up in 2013 and the outcome of disease or death was retrieved based on health-care medical records according to the unique medical insurance ID. Cox proportional hazard regression model was used to estimate the association between alcohol use and incidence of type 2 diabetes mellitus (T2DM), by drinking features and patterns.@*Results@#Out of the 6 784 participants, 3 541 participant were defined as non-alcohol drinkers and there were 15 852.2 person-years of follow-up; among which 270 new cases of T2DM were diagnosed withthe crude incidence density of non-alcohol drinkers at 1 703.2/100 000 person-years. The other 3 243 subjects were classified as alcohol drinkers and there were 14 509.8 person-years of follow-up; and among which 258 new cases of T2DM were diagnosed, with the crude incidence density of T2DM at 1 778.1/100 000 person-years. Multivariate COX proportional hazard regression model indicated that there was no significantly increased risk of T2DM incidence between alcohol drinkers and non-alcohol drinkers(HR(95% CI): 1.09 (0.91- 1.30)). However, participants who averagely consumed >20 g/d or>7 times/week had a significantly increased risk of T2DM compared with non-alcohol drinkers, and the value of HR(95%CI) was 1.27 (1.02- 1.58) and 1.35 (1.00- 1.83), respectively. Among men who consumed alcoholic beverages more than 7 times/week, HR (95%CI) for T2DM incidence in the subjects who consumed 0.01 to 40 g and > 40 g once a time were 1.48 (1.05- 2.09) and 1.27 (0.80- 2.10), respectively.@*Conclusion@#Although we found no relationship between alcohol use and T2DM incidence overall, alcohol use more than 20 g/d or more than 7 times/week would increase the risk of T2DM.

Objective To explore the clinical effect of the radial artery perforator flap on repairing soft tissue defect after palm postoperative scar contracture. Methods Eighteen patients with palm scar contracture were selected. The palm soft tissue defect was repaired by radial artery perforator flap after the operation of scar removal and soft tissue release. The areas of soft tissue ranged from 5 cm × 3 cm to 8 cm × 5 cm. The area of donor flap exceeds 20%of the wounds area, and wounds were repaired by free skin grafting. Six months after operation, the hand function was compared with that before operation. Results All the patients were followed up for 6-15 months (mean 10.8 months), all flaps survived with good shape, and flap donor site wounds were healed by skin grafting. The patients were evaluated 6 months after operation according to the Chinese Medical Hand Surgery Society of upper part of functional assessment criteria: excellent in 11 cases, good in 5 cases and general in 2 cases, but preoperative functional evaluation was excellent 0 case, good in 3 cases, general in 7 cases and poor in 8 cases. Compared with that before operation, the postoperative function was significantly improved. Conclusions It is a commendable approach of repairing soft tissue defect after postoperative palm scar contracture by radial artery perforator flap, because it can provide reliable blood supply, and significantly improve hand function with exactly clinical effect.
RESUMEN
Aim Drug resistance is one of the major hinders on cancer treatments. α-enolase ( eno1 ) was closely related to the generation and development of drug resistance. This article aims to study the effect of eno1 on cell growth and drug resistance in human chro-nic myeloid leukemia cell line K562/A02 . Methods We screened three eno1 stable silencing cells K562/A02-sheno1 and its control cells K562/A02-shcon. Cell count assay was performed to test cell growth, MTT assay was used to test cell proliferation, flow cytometry was used to test the intra-cellular Rho123 content, the expression of genes were tested by real-time PCR assay and western blot assay on mRNA level and protein level, respectively. Results eno1 was o-ver-expressed in K562/A02 cells and its expression was increased by ( 2. 85 ± 0. 56 ) times and ( 1. 43 ± 0. 05 ) times on mRNA level and protein level com-pared to K562 cells. However, there was no difference in cell growth rate between K562/A02 cells and K562 cells. K562/A02-sheno1 cells showed lower cell growth rate and higher drug sensitivity to anti-cancer drugs taxol and doxorubicin. Moreover the Rho123 content was increased in K562/A02-sheno1 cells. The expression of MDR1 decreased in both mRNA level and protein level in K562/A02-sheno1 cells. Conclusion eno1 silencing could suppress cell growth, reverse drug resistance and increase its drug sensitivity in K562/A02 cells, and the mechanism was associated with the MDR1 gene.

ObjectiveTo evaluate the diagnostic value of immunohistochemistry(IHC) for the identification and localization of Treponema pallidum(TP) in secondary syphilitic lesions.MethodsSkin tissue specimens were obtained from the lesions of 25 patients with secondary syphilis and 15 patients with dermatoses unrelated to TP infection,followed by fixation and embeding.IHC using a polyclonal antibody against TP and Warthin-Starry (W-S) silver stain were carried out respectively to detect TP in these specimens.Results TP was detected in 80.00％ (20/25) of the specimens by IHC,44.00％ by W-S silver stain (Fisher's Exact Test,P =0.046).Of the 20 IHC-based TP-positive specimens,all harbored TP in the epidermis,11 also in the dermis.The density of TP was associated with the types of skin lesions,and sequentially decreased from condyloma latum to papules,maculopapules and maculae(x2 =15.694,P =0.011 ).Spirochetes were not seen in any of the control lesional specimens.ConclusionsIHC is superior to traditional W-S silver stain for detecting spirochetes in secondary syphilitic lesions,and is of great value to the diagnosis of secondary syphilis.The accurate localization of TP by IHC may facilitate the study on the formation of syphilitic lesions.

@#ObjectiveTo study the effect of comprehensive rehabilitation on the patients with craniocerebral trauma. Methods85 cases with craniocerebral trauma were subjected to the rehabilitation training supplemented with hyperbaric oxygen and acupuncture and ultrasound therapy in addition to routine neurosurgical operation. Before and after treatment,Glasgow coma scale (GCS), Fugl-Meyer assessment (FMA) and Barthel index were assessed and compared. ResultsAfter comprehensive rehabilitation therapy, the degree of coma, limbs motion and activities of daily living were improved significantly (P<0.01).ConclusionComprehensive rehabilitation is effective on the patients with craniocerbral trauma.

Objective To observe the clinical efficacy and safety of5%imiquimod cream in the top-ical treatment of condyloma acuminatum(CA).Methods A randomized,double-blind,parallel placebo-controlled clinical study was conducted.The test drug was topically used in CA patients,three times a week for8weeks.Patients whose warts cleared completely were followed up for one month to determine recurrence rates.Results Two hundred fifty-eight patients with anogenital warts were enrolled into this trial.One hun-dred twenty-nine patients were randomly selected to receive5%imiquimod cream;129patients were ran-domly chosen to receive placebo cream.Results showed that the cure rates were12.30%,32.79%,50%,60.66%respectively in study group for2,4,6,8weeks and were4.88%,14.63%,19.51%,26.02%respec-tively in control group for2,4,6,8weeks(P
RESUMEN
<p><b>OBJECTIVE</b>To evaluate the long-term outcome of immunosuppressive therapy (IST) in patients with severe aplastic anemia (SAA).</p><p><b>METHODS</b>Hematopoietic recovery (peripheral blood cell counts, bone marrow aspirates, bone marrow biopsy, in vitro culture of hematopoietic progenitors), immunity of T lymphocyte, quality of life and side-effects of the therapy were assessed in 50 SAA patients who have survived more than 3 years after IST.</p><p><b>RESULTS</b>At 3 years, 4 years and 5 years follow-up, 81.5% (13 cases), 86.7% (13 cases) and 89.5% (17 cases) of the SAA patients reached and maintained normal peripheral blood cell counts, 93.4% (15 cases), 93.3% (14 cases) and 94.7% (18 cases) showed normal bone marrow pictures, and 37.5% (6 cases), 40.0% (6 cases) and 73.7% (14 cases) had normal yields of bone marrow cell culture, respectively. Overall, 86.0% (43 cases), 94.0% (47 cases) and 52.0% (26 cases) of the total SAA patients were normalized in peripheral blood counts, bone marrow picture and culture of hematopoietic progenitor yields, respectively. During the follow-up, 88.0% (44 cases) of the patients achieved 100 of Karnofsky scores; 26 of the 31 patients (83.9%) who received bone marrow biopsy showed normal histological pictures, and 29 of 37 patients (78.4%) tested had normal subsets of T lymphocytes. No clonal disease was found. The late side-effects of IST were mild. All of the parameters tested were normal in 24 patients.</p><p><b>CONCLUSION</b>After IST, the hematopoietic function of bone marrow, the immunity of the T lymphocyte and the life quality were normalized with few side-effects in patients with SAA. These patients would probably be cured.</p>
