ABSTRACT
Objective:To evaluate the optimization efficacy of ropivacaine mixed with nalbuphine for epidural labor analgesia through comparison with ropivacaine mixed with sufentanil in primiparas.Methods:Four hundred and forty primiparas with a singleton fetus in vertex presentation without abnormal fetus, aged 19-36 yr, at 37-42 weeks of gestation, who were suitable and volunteered to receive epidural labor analgesia, were selected and randomly divided into observation group (NR group, n=220) and conventional group (C group, n=220).Epidural labor analgesia solution contained nalbuphine 40 mg and ropivacaine 120 mg in 150 ml of normal saline in group NR.Epidural labor analgesia solution contained sufentanil 50 μg and ropivacaine 120 mg in 150 ml of normal saline in group C. The analgesia pump was set up to deliver a 5 ml bolus dose with a 20-min lockout interval, programmed intermittent bolus 10-15 ml/h and background infusion at 2 ml/h after an initial dose of 15 ml to maintain VAS score <3.The length of labor, adverse reactions during labor analgesia, neonatal Apgar score, parameters of umbilical artery blood gas analysis and neonatal behavioral neurological assessment score were recorded. Results:Compared with group C, the incidence of urinary retention, pruritus, nausea and vomiting and fever at birth was significantly decreased in group NR ( P<0.05).The duration of the first and second stages of labor, neonatal Apgar score, pH value of umbilical artery blood, lactate concentrations, and neonatal behavioral neurological assessment score were within the normal range in both groups, and there was no significant difference between the two groups ( P>0.05). Conclusions:Compared with conventional medication, nalbuphine mixed with ropivacaine has the same efficacy when used for epidural labor analgesia in primiparas, but it has a certain optimization efficacy in terms of safety.
ABSTRACT
Objective:To compare the clinical manifestations of ocular toxoplasmosis (OT) in adult and children, and to preliminarily explore the role of intraocular fluid detection in the early diagnosis of OT.Methods:A retrospective study. From January 2018 to October 2019, 60 cases of OT patients with 60 eyes diagnosed in the Department of Ophthalmology of Beijing Chaoyang Hospital Affiliated of Capital Medical University were included in the study. The medical history information of patients was collected in parallel with slit-lamp microscopy, indirect ophthalmoscope examination, and canine toxoplasma antibody detection in aqueous or vitreous fluid. Fifty-eight cases underwent visual inspection; 2 cases did not underwent visual inspection, who were children. The visual acuity examination was carried out using the new version of the standard logarithmic visual acuity chart, which was converted into the logarithmic minimum angle of resolution(logMAR) visual acuity during statistics. According to age, the patients were divided into adult group and child group, with 12 eyes in 12 cases and 48 eyes in 48 cases, respectively. The clinical characteristics and main points of diagnosis and treatment of the two groups of patients were compared and observed. The comparison among the measurement data groups conforming and the normal distribution was performed by the independent t test. The comparison between the measurement data groups of the skewed distribution was performed by the Kruskal- Wallis test. The qualitative data were compared with χ 2 test. Results:Among the adult group and the child group, 7 (58.3%, 7/12) and 34 (70.8%, 34/48) patients with a clear history of contact with dogs and cats were in the adult group and the child group, respectively. The adult group was significantly lower than the child group, however, there was no different statistical significance ( χ 2=0.236, P=0.627). At the first visit, the self-reported blurred vision of the adult group and the child group was 10 (83.3%, 10/12) and 22 (45.8%, 22/48) cases, respectively. In the adult group and the child group, 3 (25.0%, 3/12) and 20 (43.5%, 20/46) eyes with logMAR visual acuity greater than 1.85, 8 (66.7%, 8/12) and 22 (45.8%, 22/46) eyes with logMAR visual acuity less than 0.3. The visual acuity of the adult group was better than that of the child group, and the difference was statistically significant ( Z=2.162, P=0.031). There was no statistically significant difference in the composition ratio of different clinical types of the two groups of eyes ( χ 2=1.908, P=0.385). The incidence of inflammation in the anterior segment of the eye in the adult group and the child group were 25.0% (3/12) and 56.3% (27/48), respectively; there was no statistically significant difference between the two groups ( χ 2=3.750, P=0.053). The concentration of antibodies in the vitreous humor of the affected eye in the adult group and the child group was greater than that of aqueous humor. The antibody concentrations of vitreous humor and aqueous humor were 36.51 (22.58) and 19.94 (21.78) U/ml in the children group; 45.95 (56.44) and 32.20 (38.64) U/ml in the adult group. Comparison of antibody concentrations in the vitreous humor and aqueous humor of the affected eyes in the child group showed statistically significant differences ( Z=-1.984, P=0.047). Conclusions:Compared with children with OT, adult patients with OT have better vision and mild inflammation or hyperplasia of the vitreous cavity. The detection of antibodies related to toxoplasma in the intraocular fluid is helpful for early diagnosis.
ABSTRACT
Objective:To analyze the equity of community health resource allocation available to the elderly in Shanghai to provide a reference for the optimization of their allocation and to ensure the basic medical needs of the elderly.Methods:116 community health service centers were selected as research objects. Based on the human resources and financial inputs for community health, the Gini coefficient and Theil index were used to analyze the equity of community health resource allocation in Shanghai from the service population and across geographical dimensions.Results:The Gini coefficients of in-service health technicians and total financial compensation, as based upon the dimension of serving the elderly population, were 0.116 and 0.251, respectively, while the Gini coefficients based on the geographical dimension were 0.483 and 0.329 (respectively). The results of the Theil index analysis are relatively consistent with the Gini coefficient. The equity of health human resource allocation is slightly better than that of financial investment, and the equity of health resource allocation population is better than that concerning geography. Regional differences are the main factors regarding the equity of health resource allocation of the elderly community based on geographical factors (71.47%-86.71%), intra-regional differences were the main source of equity differences in community health resources allocation based on the elderly population (52.52%-89.44%).Conclusion:The allocation structure of community health resources for the elderly in Shanghai is, on the whole, fair; but, the differences between population equity and geographical equity, and between and within regional plates, cannot be ignored.
ABSTRACT
Objective:To investigate the association between the cerebral microbleeds(CMBs)and CHA 2DS 2-VASc score in patients with non-valvular atrial fibrillation(NVAF), and to analyze the related risk factors for CMBs. Method:This was a retrospective case-control study.A total of 164 patients with NVAF who had performed brain magnetic resonance susceptibility weighted imaging in Zhejiang Hospital from January 2015 to December 2017 were included.Based on the presence of CMBs, all patients were divided into the CMBs group(n=43, 26.2%)and the non-CMBs group(n=121, 73.8%). We collected the data about clinical characteristics, CHA2DS2-VASc score and number of CMBs.The association between CMBs and CHA2DS2-VASc score was analyzed by Spearman linear test.The Logistic regression analyses was used to evaluate the association between CMBs and the risk factors, including age, hypertension, etc.Results:The incidence of CMBs was markedly increased with the increase of CHA 2DS 2-VASc score( P<0.05). Besides, the rate of CMBs ≥5 was also positively associated with CHA 2DS 2-VASc score( P<0.05). Patients in the CMBs group was significantly older than those in the non-CMBs group[(81.0±8.1)years vs.(75.4±11.2)years, P<0.01]. There were significantly differences in rates of hypertension(83.7% vs. 63.2%), moderate-severe leukoaraiosis(44.2% vs.33.9%), anticoagulant therapy(34.9% vs.19.0%)and median CHA 2DS 2-VASc score(4 vs.3)between the CMBs group and the non-CMBs group(all P<0.05). Logistic regression analyses showed that age and anticoagulant therapy were the independent risk factors of CMBs in NVAF patients(all P<0.05). Conclusion:CMBs is strongly associated with CHA 2DS 2-VASc score in patients with NVAF.Age and anticoagulant therapy are its independent risk factors.It is necessary to detect the possibility of CMBs in old NVAF patients with high CHA 2DS 2-VASc score before and during anticoagulant therapy.
ABSTRACT
Objective:To investigate the accumulation of porphyrin metabolites [uroporphyrinogen (UP) Ⅰ and coproporphyrinogen (CP) Ⅲ] induced by 5-aminolevulinic acid (5-ALA) in the urine of rats with colorectal cancer.Methods:The rat model of colorectal cancer was established by dimethylhydrazine (DMH). Urine samples were collected from 30 colorectal cancer rats (colorectal cancer group) and 30 normal rats (normal group). Each animal was given 5-ALA (50 mg/kg) by gavage, and urine was collected after 2, 4, 6 and 8 h. The contents of urinary porphyromogen Ⅰ and porphyromogen faecalis Ⅲ in urine were detected by high performance liquid chromatography (HPLC).Results:There was no significant difference in the contents of UP Ⅰ and CP Ⅲ in urine between colorectal cancer group and normal group before oral administration of 5-ALA ( P>0.05). After oral administration of 5-ALA, the contents of UP Ⅰ and CP Ⅲ in urine of colorectal cancer group were significantly higher than those of normal group ( P<0.05). The contents of UP Ⅰ and CP Ⅲ in urine of colorectal cancer group reached the highest value at 4 hours. According to the receiver operating characteristic (ROC) curve drawn from 4-hour test results, the threshold value of UP Ⅰ for colorectal cancer diagnosis was 50.43 μmol/g, with corresponding sensitivity 96.7%, and the specificity 63.3%, respectively. The threshold value of CP Ⅲ for colorectal cancer diagnosis was 108.85 μmol/g, with corresponding sensitivity 66.7%, and the specificity 86.7%, respectively. Conclusions:The accumulation of porphyrin metabolites induced by 5-ALA in the urine of rats with colorectal cancer is significant. The porphyrin metabolites in urine may be a new tumor marker of colorectal cancer, which provides an experimental basis for the diagnosis of colorectal cancer.
ABSTRACT
Objective:To explore the effect and mechanism of 5-Aminolevulinic Acid-Photodynamic Therapy (5-ALA-PDT) on the apoptosis of the human colonic carcinoma HT-29 cells.Methods:HT-29 cells were cultured in vivio and divided into four groups: blank control group, 5-ALA group, PDT group and 5-ALA-PDT group.The control group was not given photosensitizer and light treatment; 5-ALA group was given photosensitizer ; PDT group was given light treatment; 5-ALA-PDT group was given photosensitizer and light treatment at the same time. Flow cytometry was used to observe the apoptosis of HT-29 cells. Reverse transcription polymerase chain reaction (RT-PCR) was used to observe the expression of B-type lymphoma-2 (Bcl-2) and Bcl-2 associated X protein (Bax) in HT-29 cells. Ultraviolet spectrophotometry was used to detect the expression of Caspase-3. Results:The apoptotic rate of 5-ALA-PDT group was significantly higher than that of blank control group, 5-ALA group and PDT group ( P<0.05). Compared with the blank control group, 5-ALA-PDT group and PDT group, the expression of Bcl-2 in the 5-ALA-PDT group was statistically significant ( P<0.05), but there was no significant difference in Bax expression among the four groups ( P>0.05). The expression of Bax/Bcl-2 in 5-ALA-PDT group was significantly higher than that in blank control group, 5-ALA group and PDT group ( P<0.05). The expression of Caspase-3 in 5-ALA-PDT group was significantly higher than that in blank control group, 5-ALA group and PDT group ( P<0.05). Conclusions:5-ALA-PDT can induce apoptosis of HT-29 cells, and its mechanism may be related to the induction of apoptosis through Bax/Bcl-2 pathway.

ABSTRACT
China has entered an aging society.The situation of elderly-care has become immensely serious.The task of providing health care for the elderly demands immediate and urgent attention,in which traditional Chinese medicine plays unique advantages.Currently,with government support,elderly health care provided by TCM has achieved good results,and reached an unprecedented rapid rising stage of opportunities.However,there is still quite a gap between the elderly health care services provided by traditional Chinese medicine and the increasing demand.By examining the current situation of elderly health care provided by TCM,this paper reveals the difficulties and challenges faced by elderly health care provided by TCM,such as lack of TCM geriatric professionals,disconnection with the Internet,impairment of necessary facilities.By studying the current status,this paper proposes strategies to promote elderly health care provided by TCM as an active response to the call of the aging population.
ABSTRACT
Objective To assess the value of MSCT in the diagnosis of traumatic pancreatic injury.Methods The clinical and MSCT examination data of 38 patients with pancreatic injury admitted to our hospital were retrospective reviewed.Radiographic pancreatic injuries were classified as superficial or deep lesions,according to the depth of the injury to pancreas.Superficial lesions were defined as the hematomas or lacerations <50% of thickness of pancreas,deep lesions as the hematomas or lacerations >50% of thickness of pancreas.Results In 38 patients,32 patients underwent operative treatment,and other 6 patients underwent nonoperative treatment,including 20 patients with superficial injury and 18 patients with deep injury.The overall diagnostic coincidence rate of CT was 89.5%(34/38),and diagnostic coincidence rate for deep injury was 100%(18/18)with injury of the main pancreatic duct.Five cases of pancreatic injury were detected by CT enhancement and post-processing technique,and CT examination was considered negative in 4 cases of superficial injury.CT showed intrapancreatic or peripancreatic hematomas in 16 cases,pancreatic tear or laceration in 17 cases,pancreatic contusion in 10 cases, peripancreatic pseudocyst in 11 cases,dilation of the main pancreatic duct in 3 cases,traumatic pancreatitis in 20 cases and peripancreatic infection with abccess in 4 cases.Pancreatic injury presented as pancreatic or peripancreatic hematomas in early stage (within 7 days)and subsequently evolved into pancreatic tear or laceration and pseudocyst.Pancreatic injury was located in the pancreatic head in 10 cases,both in pancreatic head and neck in 1 case,in pancreatic neck in 10 cases,both in pancreatic neck and body in 1 case,in pancreatic body in 2 cases,both in pancreatic body and tail in 7 cases and in pancreatic tail in 7 cases.Pancreatic contusion was mainly located in pancreatic head (8/10, 80%).19 cases of simple pancreatic injury and 19 complex ones were showed in this study.Conclusion The diagnostic coincidence rate of CT for deep pancreatic injury is high with dilatation of the main pancreatic duct.CT findings of pancreatic injury are related to the time,site and degree of the pancreatic injury.CT enhancement and post-processing technique can improve diagnostic rate.
ABSTRACT
Objective To compare the difference of three methods testing the antibiotic susceptibility of mucoid Pseudomonas aeruginosa in order to provide accurate and reliable antibiotic susceptibility result for clinic.Methods A total of 630 mucoid Pseudomonas aeruginosa were collected from Linyi People′s Hospital during January 2015 to December 2016.They mainly come from respiratory medicine and the most common specimen source was sputum.All specimens were examined in 2 h.The strains isolated from the same patient were discarded.Antibiotic susceptibility was tested by the automatic microorganism analyzer VITEK2 compact, E-test, which was reference method, and K-B disk.The results of three methods were analyzed and compared by χ2 test.Results The result of E-test showed that antibiotic sensitivity of 630 mucoid Pseudomonas aeruginosa was above 52.7% except for Cefepime (39.2%).The result of K-B disk was compared with E-test, the antibiotic sensitivity of mucoid Pseudomonas aeruginosa to imipenem (72.4% vs 52.7%) and amikacin (48.6% vs 71.1%)had significant difference (χ2=8.283 7 and 10.533 8, P<0.05).The result of VITEK2 compact showed that the antibiotic susceptibility of mucoid Pseudomonas aeruginosa to imipenem(70.8% vs 52.7%), cefepime(60.8% vs 39.2%), gentamicin (87.6% vs 74.1%)and levofloxacin(81.3% vs 65.4%) was significant higher than the result of E-test (χ2=6.935 2,9.331 2,5.885 6 and 6.466 5, P<0.05).For tobramycin, piperacillin/tazobactam and ciprofloxacin, the result of three methods is more consistent.Compared to VITEK2 compact, the consistency between K-B disk and E-test was higher.The rate of very major error and major error were between 0.0%-4.8% (Amikacin 12.2%) and minor error was 4.6%-20.3%.Conclusions The drug sensitivity of mucoid Pseudomonas aeruginosa is different between various methods.The result of K-B disk and E-test using blood MH is more reliable than VITEK2 compact.
ABSTRACT
Objective To analyze the antibiotic resistance of Branhemella catarrhalis strains isolated from sputum specimens of patients with lower respiratory tract infections from Linyi, Shandong Province, and to explore the relationship between bro genotypes of the strains and their resistance to antibiotic agents.Methods Sputum specimens were colleted from the patients with lower respiratory tract infections in Linyi People ’ s Hospital from the January 2010 to December 2014.The specimens were inoculated into 4 different disks for bacterial isolation and cultivation.β-lactamase detection and drug sensitivity tests were performed, and PCR coupled with restriction endonuclease analysis was employed for bro genotyping.χ2 test was used to compare drug resistance of strains with different bro genotypes.Results A total of 497 Branhemella catarrhalis strains were isolated in five years, among which 221 strains were isolated in winter.All strains were sensitive to ertapenem and chloramphenicol, and the resistance rates to amoxicillin/clavulanate and cefaclor were low (≤2.8%).The strains were highly resistant to compound sulfamethoxazole, erythromycin and ampicillin (47.6%-89.8%), and there was a trend of increasing resistance rates with the year, but no statistically significant difference was observed ( P >0.05 ) .β-lactamases was positive in 412 strains (82.9%), and all of these strains were positive for bro gene, and the resistances to erythromycin, compound sulfamethoxazole, levofloxacin and ampicillin were higher in bro positive strains than those in bro negative strains (χ2 =12.16, 16.18, 8.41 and 200.00,P0.05 ).Conclusions Most of Branhemella catarrhalis clinical isolates are β-lactamase producing strains, and bro-1 is the most common genotype.Strains are highly sensitive to carbapenems, cephalosporins andβ-Lactamaseinhibitors, which can be recommended for the treatment of Branhemella catarrhalis-related respiratory tract infections.
ABSTRACT
Objective To investigate the drug sensitivity of mucoid Pseudomonas aeruginosa to common antibiotics and the expression of β-lactamase-resistant phenotype.Methods The specimens were inoculated onto different disks to isolate and cultivate bacteria.The antibiotic susceptibility of mucoid Pseudomonas aeruginosa isolates was detected and judged by CLSI 2013.The detection of drug resistance was done by Kirby-Bauer (K-B) method and β lactamase-resistant phenotype was detected by E-test.SPSS19.0 was used to statistic data and x2 test was used to compare the antibiotic susceptibility between different groups.For all statistical test,a P values less than 0.05 was defined as statistically significant.Results The susceptibilities of mucoid Pseudomonas aeruginosa to the regular antibiotics were above 70％,of which the sensitivities to amikacin,to bramycin,gentamicin,imipenem and meropenem were higher than 90％.The positive rate of ampler class C β-lactamase (AmpC) was 28.3％ (56/198).The drug sensitivity of positive strains was lower than that of the negative strains,and the differentiation was significant to piperacillin-tazobactam,amikacin,ceftazidime,levofloxacin,ciprofloxacin and aztreonam (x2 =3.89-14.45,all P ＜0.05).The positive rate of extended spectrum β-lactamase(ESBLs) was 10.6％ (21/198).The drug sensitivity to ceftazidime and aztreonam of positive strains[42.9％ (9/21) and 57.1％ (12/21),respectively].It was lower than that of the negative strains [73.5％ (130/177) and 72.3％ (128/177)],x2 =5.06 and 19.24,both P ＜ 0.05.The difference of the other antibiotics was not significant(x2 =0.01-3.47,all P ＞0.05).The positive rate of metallo-β-lactamase (MBL) was 19.7％ (39/198),and the drug susceptibility of positive strains was lower than that of negative strains except gentamicin and aztreonam(x2 =4.07-15.99,all P ＜ 0.05).All the detected strains were Klebsiella pneumonia carbapenemase (KPC) negative.Conclusions The antibiotic susceptible rate of mucoid Pseudomonas aeruginosa was high,but some enzyme-produced strains were lower.The clinician should adjust medicine program by the results of laboratory.
ABSTRACT
Objective To discuss the distributional characteristics and drug-resistance of Enterococcus species isolated from urine specimens.Methods 3096 middle-segment urine specimens were collected since January to December in 2011 for culture.The identification of pathogenic bacteria and antibiotics sensitivity tests were carried out with VITEK2-compact combined with GN,AST-GN13,GP,AST-GP67,and antibiotics sensitivity tested performed by K-B and E-test at the same time.The results were determined by CLSI 2011.Results 1248 of 3096 pathogenic bacteria were isolated (40.31％).549 strains of Escherichia coli were detected (43.99％) which was the most common and 159 strains of Enterococcus were detected (12.74％) which was the second most common.The Enterococcus detection rate in woman (15.02％)was higher than that in man (10.35％),in out-patients (15.54％) than the that in hospitalized patients (12.49％),and in the patients of non-surgical departments (13.65％) than those of surgical departments (11.38％).The Enterococcus was absolutely sensitive to tigecycline,and the sensitive rate to vancomycin and linezolid were over 90％.The antibiotics sensitivity was higher for Enterococcus faecalis than that for Enterococcus faecium,and in surgical departments than non-surgical departments.Conclusions The detection rate of Enterococcus in urinary tract infection patients is quite high and varied between sexes and departments.The difference of drug resistance between species is obvious,and the bacteria species should be identified in order to use the antibiotics reasonably to postpone the development of drug resistant strains.

The relationship between baseline clinical and echocardiographic characteristics and the time to recurrence during follow-up was evaluated using Cox multivariate analysis.</p><p><b>RESULTS</b>A total of 280 patients who received single catheter ablation procedure were included in the study, 3 patients died and there were 50 patients lost to follow-up. A total of 227 patients with AF (163 paroxysmal and 64 non-paroxysmal ) were enrolled in the final analysis. During a median follow-up of 51 months (41-56 months), 109 patients experienced AF recurrences and the recurrence rate after catheter ablation ( ≥ 3 years) was 48.0% (109/227). Cox multivariate analysis showed that the high CHADS2 score (HR: 1.417, 95%CI 1.194-1.682, P < 0.001) and AF non-termination during ablation (HR: 2.077, 95%CI 1.380-3.126, P = 0.043) were risk factors of AF recurrence. AF recurrence rates in the termination and non-termination group were 41.0% (75/183) and 77.3% (34/44), respectively. In the AF termination group, the recurrence rates and the median recurrence free time in patients with CHADS2 score ≥ 3 were 80.0% (12/15) and 1 year, respectively. In the non-AF termination group, the recurrence rates in patients with CHADS2 score = 0, CHADS2 score = 1-2 and CHADS2 score ≥ 3 were 60.0% (6/10), 77.8% (21/27) and 100% (7/7), respectively; the median recurrence free time of patients with CHADS2 score = 0, CHADS2 score = 1-2 and CHADS2 score ≥ 3 were 30 months, 12 months and 6 months, respectively.</p><p><b>CONCLUSIONS</b>CHADS2 score is a predictor of AF recurrences after catheter ablation. Patients with high CHADS2 score is associated with higher risk of long-term ( ≥ 3 years) AF recurrences.</p>

Objective To explore the potential legal issues about mandatory nursing intervention in psychiatric wards,and put forward the strategies of nursing management.Methods The causes and the potential legal issues of the action of psychiatric nurses to carry out mandatory nursing intervention were analyzed.Results There were legal issues on the right to life and health,the right of informed consent,the right of personal freedom and the right of personality respected about mandatory nursing intervention in psychiatric wards and there might be negligence,misconduct and responsibility of violating the laws and regulations.Conclusions While carrying out mandatory nursing intervention in psychiatric wards,nurses need to respect the patients,make related informed well,protect various related rights of patients and families,implement seriously the relevant system so as to make mandatory nursing interventions more humanized,scientific,standardized,programming,and avoid the occurrence of medical disputes.
ABSTRACT
Objective To investigate the distribution and antibiotic susceptibilities of quantitatively cultivated bacteria from bronchoalveolar lavage fluid (BALF) samples. Methods Totally 312 BALF samples were streak inoculated to chocolate,blood and MAC plates with 10 μL annulus,and the bacterial colony ＞ 104 CFU/mL was considered pathogenic bacteria. The identification of pathogenic bacteria was carried out with Vitek 2-Compact,and Kirby-Bauer disc agar diffusion method,Etest and dilution method were used for antibiotics sensitivity test.Results Totally 216 (69.2％) strains of pathogenic bacteria were isolated.The major gram-negative strains were Pseudomonas aeruginosa,Acinetobacter baumannii,Klebsiella pneumoniae and Escherichia coli, and the major gram-positive strains were Staphylococcus aureus,Streptococcus pneumoniae and Staphylococcus epidermidis.The resistance rate of Pseudomonas aeruginosa to aztreonam was high,but lower than 30％ to piperacillin/tazobactam,imipenem,cefepime,ofloxacin,ceftazidime and amikacin.Staphylococcus aureus was highly resistant to erythromycin,benzylpenicillin and clindamycin,but it was sensitive to furadantin,vancomycin,quinupristin/dalfoprisdn,tigecycline and linezolid.Conclusion The positive rate of BALF cultivation is high,and the main pathogenic bacteria Pseudomonas aeruginosa, Acinetobacter baumannii, Klebsiella pneumoniae, Staphylococcus aureus and Escherichia coli are resistant to several commonly used antibiotics.
ABSTRACT
ObjectiveTo study the intelligence quotient(IQ) profile of the children with idiopathic generalized tonic-clonic seizure (GTCS) and the factors influencing IQ of them.MethodsAll 28 children with GTCS were selected who were aged 9 ～ 16 years in 20 GTCS families in a mountain area of the south of Anhui Province,all available healthy siblings of the children included in the epilepsy group,did not have epilepsy,and were nearest in age to the children with GTCS ( control group 1 ),and thirty children aged 9 ～ 16 years old who had lived in the same village ( control group 2) entered into our study.The IQ was studied of the three groups of children and the factors influencing IQ of children with GTCS at the same time.The data were input SPSS12.0 and analyzed.ResultsThe IQ of children with GTCS(85.64 ±20.57)was lower than that control group 1( 103.39 ± 11.17)and the control group 2 ( 106.17 ± 11.67).The difference between children with GTCS and the two control groups were significant for almost all the subtest quotients except completion of drawing and picture arrangement.No significant differences were found between the control group 1 and the control group 2 on the IQ and the subtest quotients.IQ scores of children with GTCS showed significant linear correlation with father's education( r=0.453,P＜0.01 ),age at onset of epilepsy( r=0.506,P＜0.01 ),duration of seizure disorder( r=-0.533,P＜0.0l ),status epilepticus( r=-0.732,P＜0.01),total number of seizures( r=-0.761,P＜0.01) and seizure frequency ( r=-0.708,P ＜ 0.01 ).ConclusionThe IQ scores of the children with idiopathic GTCS are lower significantly than general children population.Epilepsy-related variables affecting IQ scores of the children with idiopathic GTCS are duration of seizure disorder,status epilepticus,age at onset of epilepsy,total number of seizures,seizure frequency.
