ABSTRACT
Objective@#To analyze the impact of persistent obesity on their lung function, so as to offer insights for implementing intervention measures to increase lung function in obese school age children.@*Methods@#A total of 335 children from the Sheyang Mini Birth Cohort established in 2009 in Yancheng City, Jiangsu Province, who participated in the follow up at the ages of 7 years (2016) and 10 years (2019), were selected as the study participants. Physical measurements including height, weight, and lung function were recorded. According to the World Health Organization standard, that is, gender and age specific to correct the body mass index to calculate the body mass index Z score, was used to evaluate the obesity status of children at the age of 7 and 10. Children were divided into four groups, including sustained non obesity group, restored obesity group, newly classified obesity group, and persistent obesity group. Meanwhile, the lung function prediction equations recommended by the Global Lung Function Initiative were used to standardize the lung function indexes of children. Pulmonary function differences among these groups were examined, and the relationship between childhood obesity and pulmonary function was longitudinally analyzed using generalized estimating equations.@*Results@#The prevalence of obesity were 9.0% and 16.1% at the age of 7 and 10 years, respectively. The proportion of both newly classified and persistent obesity group were 8.1%, respectively. The forced expiratory volume in one second (FEV 1) and forced vital capacity (FVC) were (1 269.90±202.70) and (1 415.70±230.00) mL, respectively, at the age of 7 years. FEV 1 and FVC at the age of 10 years were (1 440.80±403.20) and (1 555.60±517.60) mL, respectively. Cross sectional analysis at age 7 showed that forced expiratory flow at 75% vital capacity (FEF 75 ) ( β=-0.52, 95%CI =-0.96--0.07) and maximal mid expiratary flow (MMEF) ( β=-0.45, 95%CI =-0.89--0.00) were significantly lower in obese children compared to their non obese peers ( P < 0.05). Longitudinal analysis indicated that obese children had lower levels of lung pulmonary function, with a statistically significant difference in FEV 1 ( β=-0.44, 95%CI=-0.85--0.02, P <0.05). There was no significant difference among the various obesity groups ( P >0.05), while gender stratified results revealed significant reductions in FEV 1/FVC in newly classified obese girls at age 10 years ( β=-1.76, 95%CI =-3.13--0.38) and in MMEF in persistently obese girls at age 10 years ( β=-1.44, 95%CI = -2.79- -0.09) ( P <0.05).@*Conclusion@#Obesity may contribute to reduced lung function levels in school aged children, with newly classified and persistent obesity having more pronounced effects on lung function in girls.
ABSTRACT
Objective @# To investigate the phenotype of amoxicillin ( AMX) unstable resistant Helicobacter pylori (Hp) evolving into AMX stable high level resistance and the detection of its mutated genes．@*Methods @#Using the frozen Hp strain H390 as the starting strain，the clones resistant to AMX were continuously cultured on the medium with increasing AMX concentration，and the minimum inhibitory concentration ( MIC) of the resistant clones was detected．After frozen at －80 ℃ for 3 months，the drug resistance was stable according to whether the MIC de- creased after frozen storage． Genome sequencing analysis and efflux pump inhibition assay were performed on cloned H390r and parental strain H390 with the highest AMX MIC value，and gene mutations associated with the high level AMX resistance obtained by H390r were detected and identified. @*Results @#Four AMX high level resistant clones were obtained by AMX screening with MICs of 12，32，64 and ≥ 256 mg / L ，respectively，and none of the MICs were altered after freezing at －80 ℃ . Compared to the parental strain H390，the AMX stable resistant clone H390r had mutations in several genes，including hefC encoding the RND efflux system，hopB and hopC encoding the pore proteins and ftsI encoding the penicillin binding protein ，which were associated with AMX resistance. H390r was substantially reduced in MIC to AMX in the presence of efflux pump inhibitors．@*Conclusion @#AMX can screen stable resistant clones from unstable resistant Hp．H390r had mutations in hefC，hopB，hopC，and ftsI asso- ciated with AMX resistance．These mutations may be the main reason why H390r acquired a stable high level of re- sistance to AMX.
ABSTRACT
ObjectiveTo predict whether antiviral therapy is required in patients with chronic hepatitis B virus （HBV） infection and an age of ≤30 years by establishing a noninvasive model， and to investigate the diagnostic value of this model. MethodsA retrospective analysis was performed for the clinical data of 175 patients with chronic HBV infection who were admitted to Shenzhen Third People’s Hospital from January 2017 to January 2023 and met the inclusion criteria， and according to the results of liver biopsy， they were divided into treatment group with 41 patients （with indications for antiviral therapy） and observation group with 134 patients （without indications for antiviral therapy）. The two groups were analyzed in terms of the indicators including clinical data， imaging examinations， and serum biochemical parameters. The univariate and multivariate Logistic regression analyses were used to investigate the parameters affecting the indication for antiviral therapy， and different models for predicting the need for antiviral therapy were constructed based on related parameters. The receiver operating characteristic （ROC） curve was used to compare the diagnostic value of different models. The independent-samples t test was used for comparison of normally distributed continuous variables between groups， and the Mann-Whitney U rank sum test was used for comparison of non-normally distributed continuous variables between groups； the chi-square test or the Fisher’s exact test was used for comparison of categorical data between groups. ResultsThere were significant differences between the treatment group and the observation group in alanine aminotransferase， ferritin， total cholesterol （CHOL）， triglyceride， platelet count， liver stiffness measured by sound touch elastography （STE）， and procollagen III N-terminal propeptide （PIIIP） （all P<0.05）. The multivariate Logistic regression analysis showed that CHOL （odds ratio ［OR］=0.4， 95% confidence interval ［CI］： 0.2 — 1.0）， STE （OR=1.5， 95%CI： 1.0 — 2.1）， and PIIIP （OR=1.1， 95%CI： 1.0 — 1.1） were independent predictive factors for the indications for antiviral therapy. Model 1 （STE+PIIIP+CHOL）， model 2 （STE+PIIIP）， model 3 （STE+CHOL）， model 4 （PIIIP+CHOL） had an area under the ROC curve of 0.908， 0.848， 0.725， and 0.725， respectively， while STE， PIIIP， and CHOL used alone had an AUC of 0.836， 0.725， and 0.634， respectively， suggesting that model 1 had the largest AUC， with a specificity of 77.34% and a sensitivity of 96.36%， and had a significant difference compared with STE， PIIIP， CHOL， and the models 2， 3， and 4 （Z=0.21， 3.08， 3.06， 3.23， 0.89， and 0.88， all P<0.05）. ConclusionThe noninvasive model established based on CHOL， STE， and PIIIP has a good value in predicting the need for antiviral therapy in patients with chronic HBV infection and an age of ≤30 years.
ABSTRACT
Background@#There is no standard cut-off value of serum IgG4 concentration and serum IgG4/total IgG ratio for the diagnosis of IgG4-related disease (IgG4-RD) or as a marker of treatment responses. We aimed to explore this issue through a retrospective cohort analysis of adults in southwest China. @*Methods@#The diagnostic performance of serum IgG4 concentration and IgG4/IgG ratio for IgG4-RD was evaluated in a retrospective analysis of 177 adults newly diagnosed as having IgG4-RD and 877 adults without IgG4-RD. Dynamic analysis was performed to evaluate the significance of serum IgG4 concentration on IgG4-RD treatment responses. @*Results@#The serum IgG4 concentration differed according to sex. The optimal cut-off values of serum IgG4 concentration and IgG4/IgG ratio for IgG4-RD diagnosis were 1.92 g/L and 0.12 in males and 1.83 g/L and 0.11 in females, respectively. For patients with serum IgG4 concentration >2.01 g/L, the cut-off values in the total population were >3.00 g/L and 0.19, respectively. The median serum IgG4 concentration decreased over time, and the decrease rate increased over time. The serum IgG4 concentration significantly decreased at >1 week post-treatment (P=0.004), and the median decrease rate was close to 50% at >4 weeks post-treatment. @*Conclusions@#Serum IgG4 can be a good indicator for IgG4-RD diagnosis; however, different diagnostic cut-off values should be determined according to sex. The decreasing rate is more conducive than the serum IgG4 concentration to monitor treatment efficacy. The IgG4/IgG ratio did not improve the diagnostic efficacy for IgG4-RD.
ABSTRACT
Background The influencing factors of noise hazards in the automotive manufacturing industry are complex, diverse, and mutually correlated, resulting in significant health impacts on workers. Objective To explore the application of generalized estimating equations (GEE) to analyze the factors affecting high-frequency hearing loss among noise-exposed workers in an automotive manufacturing company, guiding enterprises to scientifically carry out employee hearing protection programs. Methods The data of occupational health field evaluation and occupational health surveillance of an automobile manufacturing company for five consecutive years from 2018 to 2022 were collected, and 806 noise-exposed workers with pure tone hearing test results for all five consecutive years were selected as study participants. The retrieved indicators were gender, physical examination year, noise intensity, blood pressure, white blood cell counts, red blood cell counts, platelet counts, concentrations of hemoglobin, alanine transaminase, aspartate aminotransferase, smoking, drinking, etc. Gender, noise intensity, blood pressure, white blood cell counts, red blood cell counts, concentrations of hemoglobin, platelet counts, glutamate aminotransferase, glutamate aminotransferase, smoking, and drinking were set as independent variables, and occurrence of high-frequency hearing loss was set as a dependent variable, and GEE were constructed by using the statistical software of SPSS 20.0 to analyze the influencing factors of high-frequency hearing loss. Results Of the 806 workers, 698 were male (86.6%) and 108 were female (13.4%). The detection rates of high-frequency hearing loss in each year from 2018 to 2022 were 66.4% (535/806), 69.8% (563/806), 70.0% (564/806), 68.9% (555/806), and 68.2% (550/806), respectively. The detection rate of high-frequency hearing loss in the company was varied significantly by gender, lowered white blood cell counts, lowered red blood cell counts, lowered platelet counts, smoking, and drinking (P<0.05). The results of GEE analysis showed that after adjusting for selected confounding factors and excluding interaction effects, the risk of high-frequency hearing loss was higher in men than in women (P=0.001; OR=1.907, 95%CI: 1.286, 2.829); it was higher in workplace with disqualified noise intensity than in those without (P=0.043; OR=1.289, 95%CI: 1.009, 1.648); it was also higher in smokers than in non-smokers (P=0.004; OR=1.507, 95%CI: 1.137, 1.999). Conclusion Gender, noise intensity, and smoking are the main influencing factors of high-frequency hearing loss in noise-exposed workers in this automobile manufacturing company. Controlling smoking and reducing noise exposure intensity may reduce the occurrence of high-frequency hearing loss in workers.
ABSTRACT
【Objective】 To explore the recruitment and retention strategy of blood donors by investigating the age composition of blood donors in some areas of China, so as to promote blood donation and enhance clinical blood supply. 【Methods】 Through the working platform of Practice Comparison Working Group of China’s Mainland Blood Collection and Supply Institutions, the average age and age composition of blood donors from 22 blood centers were collected, and statistical analysis was conducted after eliminating invalid data. 【Results】 The median average age of blood donors during the survey year was 30.02.The median age in 2.89% of the blood centers was lower than 25. The average age of different genders was statistically significant only in 2018(P<0.05). Fot first-time blood donors, the median constituent ratio of donors <25 and ≥25 years old was 54.53% and 44.28%, with median retention rate at 10.30% and 9.61%, respectively. The median overall participation rate of blood donors was 2.7%, with median participation rate of blood donors <25 years old at 5.1%. 【Conclusion】 The recruitment and retention of blood donor is crucial to enhance clinical blood supply. Blood donors <25 years old, with a longer period for future donation, should be the main target of blood donation recruitment. Meanwhile, the revision of upper age limit for blood donation is another important initiative to grow the blood donor pool.
ABSTRACT
Objective:To investigate the clinical situation of 201 emergency adult sudden death patients, and analyze the influence of white blood cell count and arterial blood lactate level on prognosis.Methods:The clinical data of 201 patients diagnosed with sudden death in the emergency department of Medical College of Cangzhou people's Hospital from January 2017 to January 2021 were retrospectively analyzed. The gender, age, disease composition and etiology of the patients were statistically analyzed. The independent sample t-test was used to compare the measurement data with normal distribution, the χ 2 test or Fisher exact probability method was used to compare the counting data between groups, and the logistic regression model was used to screen the risk factors of emergency death, and the impact of white blood cell count and arterial blood lactate level on the prognosis was analyzed. Results:After active rescue, 11.44% (23/201) of the patients were successfully rescued, and 88.56% (178/201) of the patients were ineffective; ≥46-≤65 years old was the age group with high incidence of sudden death (55.22%(111/201)). The proportion of male (43.28% (87/201), 23.38% (42/201)) in the age group of ≥46-≤65 years old and the age group over 65 years old were higher than that of female (11.94% (24/201), 14.43% (29/201)), with a statistically significant difference (χ 2=4.801, 9.209; P=0.028, 0.002). In the past history of sudden death patients, the proportion of cardiovascular disease (53.23% (107/201)) was the highest; the proportion of patients may have inducements before sudden death was 74.13% (149/201), the proportion of patients have premonitory symptoms before sudden death was 67.66% (136/201), and sudden cardiac death was the first cause. Logistic regression analysis showed that white blood cell count ( OR=4.442,95% CI: 1.898-10.395), arterial blood lactic acid concentration ( OR=4.272,95% CI: 2.024-9.016), and albumin concentration ( OR=2.657,95% CI: 1.302-5.422) were independent risk factors affecting emergency sudden death patients ( P values were 0.001, <0.001, 0.007, respectively). Conclusions:There are some differences in gender, age and past history of adult sudden death patients. Most of them have premonitory symptoms and inducements. Sudden cardiac death is the primary cause. The increases of white blood cell count and lactic acid level, the decrease of albumin level are the risk factors of sudden death.

Objective@#To retrospectively analyze the differential diagnosis and treatment strategy of neonatal intestinal perforation caused by neonatal necrotizing enterocolitis (NEC) and Hirschsprung′s disease (HD).@*Methods@#The clinical data of 42 cases with NEC and 22 cases with HD combined with intestinal perforation from Ja-nuary 2012 to January 2017 admitted at Fujian Provincial Maternity and Children′s Hospital were collected, the proportion of premature infants, and the proportion of low birth weight infants, age of onset, preoperative clinical symptoms and surgical treatment was compared between the two groups.@*Results@#The proportion of premature infants[95.23%(40/42 cases) vs.27.27%(6/22 cases)], the proportion of low birth weight infant[90.48%(38/42 cases) vs.45.45%(10/22 cases)]and the age of onset [(14.48± 10.51) d vs.(3.18±3.43) d]were statistically different between the NEC group and the HD group, and the differences were statistically significant(all P<0.05). There were significant differences in the presence of normal defecation before the operation[71.4% (30/42 cases)vs.27.3%(6/22 cases)], and in the the defecation characteristics at the onset[95.2% (40/42 cases)vs.9.1%(2/22 cases)]between the NEC group and HD group(all P<0.05). Among 42 cases of NEC patients, 8 cases underwent intestinal anastomosis, and 34 cases underwent enterostomy because of the high risk of anastomosis.All of 22 patients with HD underwent double-lumen enterostomy.@*Conclusions@#The general conditions, preoperative manifestations and intraoperative fin-dings of the children should be comprehensively analyzed for identification.Enterostomy is recommended for NEC intestinal perforation, but if the risk of anastomosis is high, then fistula should be performed.Double-lumen fistula should be recommended for HD intestinal perforation, and enterostomy should be recommended if the two cannot be clearly distinguished.
ABSTRACT
Objective@#To analyse the mental state of patients with allergic rhinitis (AR) in Chengdu.@*Methods@#One thousand five hundred and thirty-six AR patients from Sichuan Provincial Integrated Traditional Chinese and Western Medicine Hospital, West China Hospital of Sichuan University, Affiliated Hospital of Chengdu University of Traditional Chinese Medicine, Sichuan People′s Hospital, Sichuan Second Hospital of Traditional Chinese Medicine were selected from July 2013 to January 2018. Eight hundred and twenty-seven patients were screened into study group by inclusion and exclusion standards. The symptom check list 90 (SCL-90) was used to group and score the mental state of these patients according to nine classification criteria: gender, BMI, age, marital status, monthly salary, disease duration, living environment, education level and working environment. Then, the scores were compared within groups. Inter-group comparison was made between the study group and the Chinese norm, and the positive factors for psychological disorders were extracted. Four symptoms in the study group, i.e. nasal itching, sneezing, clear discharge and nasal congestion, were scored on the visual analogue scale (VAS). SPSS 19.0 software was used to carry out statistical analysis. Partial correlation analysis was performed between the positive factors and the symptom scores by multiple regression statistical method.@*Results@#The total score of SCL-90 in the study group was 2.64±0.25, which was accorded with mild to moderate mental health impairment. There were 124 (15.0%) without mental health damage, 176 (21.3%) with mild damage, 474 (57.3%) with mild to moderate damage, 41 (5.0%) with moderate to severe damage and 12 (1.4%) with severe damage. The in-group comparison showed that the top three categories of different items were the living environment, gender and working environment. The scores of somatization, obsessive-compulsive symptoms, interpersonal sensitivity, depression, anxiety, psychosis, other (sleep, diet) and total average score of urban residents were higher than that of country residents (3.29±0.61 vs 2.65±0.50, 2.81±0.77 vs 2.05±0.38, 3.10±0.19 vs 2.49±0.67, 3.40±0.84 vs 2.49±0.70, 3.04±0.64 vs 2.33±0.51, 3.02±0.55 vs 2.40±0.77, 3.40±0.41 vs 2.52±0.77, 2.91±0.11 vs 2.29±0.40, Z value was 4.88, 5.25, 4.57, 5.91, 5.09, 4.63, 5.55, -4.55, respectively, all P<0.05). Women scored higher than man for somatization, interpersonal sensitivity, depression and others (2.66±0.51 vs 2.00±0.45, 3.37±0.47 vs 2.63±0.51, 3.44±0.57 vs 2.85±0.52, 3.47±0.36 vs 2.76±0.45, Z value was -5.10, -5.51, -4.86, -5.28, respectively, all P<0.05). The scores of somatization, interpersonal sensitivity, psychosis and other (sleep, diet) were higher in the indoor group than those in the outdoor group (3.49±0.64 vs 2.78±0.46, 3.33±0.30 vs 2.56±0.68, 3.28±0.60 vs 2.67±0.31, 3.50±0.85 vs 2.85±0.37, Z value was 5.31, 5.79, 4.89, 5.00, respectively, all P<0.05). The outdoor group scored higher on obsessive-compulsive symptoms, anxiety and hostility (3.44±0.40 vs 2.83±0.35, 3.40±0.50 vs 2.57±0.93, 3.34±0.88 vs 2.69±0.56, Z value was 4.96, 6.22, 5.08, respectively, all P<0.05). The inter-group comparison found that depression, anxiety, psychosis and other (sleep, diet) could be partially correlated with VAS scores as 4 positive factors. The results of partial correlation analysis showed that depression was positively correlated with sneezing and nasal runny discharge, anxiety was positively correlated with nasal itching and nasal obstruction, psychosis was positively correlated with nasal itching and sneezing, and other (sleep, diet) was positively correlated with nasal runny discharge and nasal obstruction.@*Conclusion@#AR patients have mild to moderate mental health impairments, which are correlated with AR symptoms.

ABSTRACT
Objective@#To explore the incidence regularity and characteristics of pneumoconiosis among migrant workers in Shiyan city, and to provide a basis for making policies about pneumoconiosis prevention and treatment among migrant workers.@*Methods@#In September 2018, 338 cases of pneumoconiosis among migrant workers and 354 cases of pneumoconiosis among non-migrant workers were collected between 2013 and 2017. The proportions of pneumoconiosis types, the age and seniority of onset workers, the severity grade of pneumoconiosis, the type of pneumoconiosis, the type of work and regional distribution, etc. were analyzed.@*Results@#The age at onset of pneumoconiosisand the length of service of migrant workers and non-migrant workers in Shiyan city were significantly different (t=2.237, 3.208, P<0.05) . The proportion of pneumoconiosis stage was significantly different from that of non-migrant workers (χ2=47.897, P<0.05) , among migrant workers, the types of pneumoconiosis were mainly silicosis (308 cases, 91.1%) , coal worker's pneumoconiosis (29 cases, 8.6%) . The leading work types are rock drilling (115 cases, 34.0%) and blasting (105 cases, 31.1%) . The industry was mainly engaged in non-ferrous metal mining (205 cases, 60.7%) and coal (105 cases, 31.1%) . The area distribution involved each counties of Shiyan city, with Zhushan county (175 cases, 51.8%) and Yunxi county (125 cases, 37.0%) as the top two districts in number of cases. Of the cases of migrant workers, 89 cases (26.3%) had blood relationship with any others. There was no work-related injury insurance for migrant workers with pneumoconiosis.@*Conclusion@#There is a high incidence of pneumoconiosis among migrant workers in Shiyan city, featured with the phenomenon of "late occurrence" and "family clustering", so it is urgent to strengthen the prevention and treatment of pneumoconiosis of migrant workers.
ABSTRACT
Objective To explore the relationship between different airway pressure and expression of related cytokines to airway remodeling.Methods Fourty-two chronic obstructive pulmonary disease cases (COPD group) and thirty-three control cases were collected.The above cases underwent mechanical ventilation in the period of general anesthesia.According to different levels of peak inspiratory pressure(PIP), above two groups, randomly and respectively, were divided into high PIP (HPIP, 24 cmH2O) group, moderate PIP (MPIP, 22 cmH2O) group, low PIP (LPIP, 20 cmH2O) group.All positive end expiratory pressure (PEEP) was set to 5 cmH2O.Then the collection of BALF was performed before and 3 hours after applying ventilator.The related factors to airway remodeling, such as fibroblast growth factor 2 (FGF-2), transforming growth factor β1 (TGF-β1) and matrix metalloproteinase-9 (MMP-9), were measured by enzyme-linked immunosorbent assay (ELISA) and Western blot.Results 1)Beforemechanical ventilation, the levels of FGF-2, TGF-β1 and MMP-9 in COPD group were higher than control group (P<0.01).2)3 hours after mechanical ventilation, we saw significant upregulated expression of FGF-2, TGF-β1, MMP-9 in HPIP subgroup in control group (P<0.05) and the 3 factors levels of COPD group were all increased (P<0.05).Moreover, HPIP subgroup was significantly higher than MPIP and LPIP subgroup in COPD group (P<0.05).3)The expression of FGF-2, TGF-β1, MMP-9 in BALF had a positive correlation with the airway pressure levels in COPD group(P<0.01).Conclusions Under mechanical ventilation, sustained high airway pressure may enhance the expression of FGF-2, TGF-β1 and MMP-9 which may result in airway remodeling by mechanosensitive cation channel in bronchial epithelial cells, especially in COPD patients.
ABSTRACT
OBJECTIVE@#To investigate the characteristics of psychiatric comorbidity in pharyngitis patients.@*METHOD@#The psychological investigation and evaluation were done in 100 pharyngitis patients by using self-reporting inventory 90 (SCL-90). All the results were compared with healthy Chinese population, including factors of gender, age, course of disease and education level, using rank-sum test analysis, SPSS 19.0.@*RESULT@#Mild and moderate levels of psychosis were respectively noted in 65% and 14%, with high score of somatization (P < 0.05), obsession (P < 0.05), interpersonal sensitivity (P < 0.05), anxiety (P < 0.05) and other (sleep, diet, P < 0.05) compared with control group. The factor scores of obsession (P < 0.05), anxiety (P < 0.05) in male group were higher than female group. The factor scores of somatization (P < 0.05) and obsession (P < 0.05) in junior group were higher than senior group. The factor scores of somatization (P < 0.05), interpersonal sensitivity (P < 0.05) and anxiety (P < 0.05) in long course group were higher than short course group. The factor score of interpersonal sensitivity (P < 0.05) in low educated group was higher than highly educated group.@*CONCLUSION@#Psychiatric disorders are prevalent in pharyngitis patients, especially upon the factors of somatization, obsession, interpersonal sensitivity, anxiety and other (sleep, diet). Male, junior, long course patients and low educated are in high risk group.

OBJECTIVE:To observe the efficacy and safety of carboprost and Foley catheter for the expand cervix before hys-teroscopic electric resection. METHODS:80 patients with hysteroscopic operation were randomly divided into research group and control group. Research group was placed inside the vagina carboprost 1 mg 30 minutes before operation;control group was placed inside the Foley catheter 12 hour before operation. The relaxation degree of the cervix,average operative time,preoperative pain, postoperative morbidity and incidence of adverse reactions in 2 groups were observed. RESULTS:There were no significant differ-ences in the relaxation degree of the cervix,postoperative morbidity and incidence of adverse reactions between 2 groups(P>0.05). The average operative time and preoperative pain in research group were significantly better than control group,the differ-ence was statistically significant(P<0.05). CONCLUSIONS:Carboprost and Foley catheter have good efficacy and safety for ex-pand cervix before hysteroscopic electric resection,however,carboprost is better than Foley catheter in terms of average operative time and preoperative pain.
ABSTRACT
Objective To analyze the clinical distribution and drug resistance of clinically isolated strains of Acinetobacter Bau-mannii(ABA)in our hospital from January 2007 to December 2012 so as to provide the basis for the rational use of antibacterial drugs in clinic.Methods The API microbiological culture and identification system was adopted to conduct the ABA culture,identi-fication and drug susceptibility analysis on the clinical specimens submitted by various clinical department and the drug resistance of the strains was analyzed by using WHONET5.6 software.Results 791 strains of ABA were isolated in the recent 6 years,and the isolating rate of ABA in the pathogenic bacteria was 7.8%;The ABA detection was dominated by the sputum (80.4%)and the throat swab(10.9%)specimens;the distribution of isolated ABA strains were relatively widespread;the infection rates of the pa-tients were higher in ICU (18.8%),cadre wards(17.6%),respiratory medicine department(13.3%)and neurosurgery department (12.3%).During these 6 years,the drug resistance rate of less than 50% included imipenem(IPM)and cefoperazone sodium/sul-bactam,and the resistance rate in most of commonly used antibacterial drugs showed an increasing trend,especially IPM.Conclusion The drug resistance of ABA is more serious and the resistance rate of clinically isolated strains to most of antibacterial drugs in our hospital during 2007- 2012 showed an increasing trend.Dynamically monitoring the ABA distribution and the drug resistance changes conduces to guide the rational use of antibacterial drugs in clinic,prevent the nosocomial infection and reduce the generation of pan-drug resistant strains.
ABSTRACT
Objective To determine the nursing measures of patients with primary open angle glaucoma undergoing implantation of EX-PRESS device.Methods 12 glaucomatous patients with EX-PRESS miniature glaucoma device received appropriate hygienic-education preoperatively,intensive nursing services during and after surgery,as well as health instructions in the follow-up period.Results 12 patients finally recovered from the surgery.The main post-operative complications were low tension and shallow anterior chamber(2 eyes),obstruction of the device by iris (1 eye).The intraocular pressures of all these patients remained normal levels before discharge and the visual acuity were the same as those pre-operation.Conclusions The effective nursing services for patients with EX-PRESS implantation is beneficial to the rehabilitation by increasing the adherence to the follow-up schedule,contributing to better understanding the common sense of the disease and the choice of the surgery.
ABSTRACT
Objective To investigate the current situation and influencing factors of self-transcendence among the elderly people and provide the theoretical basis to improve the elderly people's self-transcendence level.Methods Totally 300 elderly people were recruited by convenience sampling from two communities in Taiyuan.They were investigated by questionnaires.Results The total score of self-transcendence was (43.83±7.29).Single factor analysis of variance and nonparametric test showed that the influencing factors of elderly people's self-transcendence level were education background,occupation before retirement,economic status,characteristics,the frequency of group activity,and the experience of significant events.Multiple linear stepwise regression analysis showed that the education background and personality characteristics were the main influencing factors on the elderly people's self-transcendence.Conclusions Elderly people's family members,health care workers,and other social workers should pay high attention to the elderly people's self-transcendence level,take measures to increase their self-transcendence level and stimulate the elderly people's enthusiasm of self-management according to the influencing factors,so as to improve the elderly people's life quality,extend the healthy life expectancy,and finally achieve the whole healthy aging.
