BACKGROUNDS:
At present, there is no consensus on the induction methods in term pregnancy with borderline oligohydramnios. This study aimed to compare the effectiveness and pregnancy outcomes of labor induction with dinoprostone or single-balloon catheter (SBC) in term nulliparous women with borderline oligohydramnios.
METHODS:
We conducted a retrospective cohort study from January 2016 to November 2018. During the study period, a total of 244 cases were enrolled. Of these, 103 cases were selected for induction using dinoprostone and 141 cases were selected for induction with SBC. The pregnancy outcomes between the two groups were compared. Primary outcomes were successful vaginal delivery rates. Secondary outcomes were maternal and neonatal adverse events. Multivariate logistic regression was used to assess the risk factors for vaginal delivery failure in the two groups.
RESULTS:
The successful vaginal delivery rates were similar between the dinoprostone group and the SBC group (64.1% [66/103] vs. 59.6%, [84/141] P = 0.475), even after adjustment for potential confounding factors (adjusted odds ratio [aOR]: 1.07, 95% confidence interval [CI]: 0.57-2.00, P = 0.835). The incidence of intra-amniotic infection was lower in the dinoprostone group than in the SBC group (1.9% [2/103] vs. 7.8%, [11/141] P < 0.001), but the presence of non-reassuring fetal heart rate was higher in the dinoprostone group than in the SBC group (12.6% [13/103] vs. 0.7%, [1/141] P < 0.001). Multivariate logistic regression showed that nuchal cord was a risk factor for vaginal delivery failure after induction with dinoprostone (aOR: 6.71, 95% CI: 1.96-22.95). There were three factors related to vaginal delivery failure after induction with SBC, namely gestational age (aOR: 1.51, 95% CI: 1.07-2.14), body mass index (BMI) >30 kg/m2 (aOR: 2.98, 95% CI: 1.10-8.02), and fetal weight >3500 g (aOR: 2.49, 95% CI: 1.12-5.50).
CONCLUSIONS
Term nulliparous women with borderline oligohydramnios have similar successful vaginal delivery rates after induction with dinoprostone or SBC, with their advantages and disadvantages. In women with nuchal cord, the risk of vaginal delivery failure is increased if dinoprostone is used in the induction of labor. BMI >30 kg/m2, large gestational age, and estimated fetal weight >3500 g are risk factors for vaginal delivery failure after induction with SBC.

Objective:To analyze the related factors affecting the use of autogenous arteriovenous fistula (AVF), and provide a theoretical basis for prolonging the service life of AVF in hemodialysis patients.Methods:This was a retrospective study. The patients undergoing AVF and using it to maintain hemodialysis (MHD) in the First Affiliated Hospital of Nanchang University from October 2004 to June 2017 were selected as study subjects to discuss the relevant factors affecting the service life of AVF. The data of general information, dialysis and laboratory examinations were collected through questionnaire surveys, hospital case system and hemodialysis record sheets. The patients were divided into the patency group and the dysfunction group according to the status of AVF, and the related factors were compared. Multivariate Cox proportional hazard model was used to analyze the influencing factors, and Kaplan-Meier survival curve was used to determine the service life of AVF, respectively.Results:A total of 187 subjects were included in the study. The patency group had 140 cases and the dysfunction group had 47 cases. There were statistically significant differences in the proportion of diabetes, the level of serum albumin, uric acid and parathyroid hormone (PTH) between the two groups (all P<0.05). Multivariate Cox proportional hazard regression analysis showed that diabetes ( HR=9.348, 95% CI 3.507-24.918, P<0.001) and hypoalbuminemia ( HR=12.650, 95% CI 2.925-54.714, P=0.001) were risk factors for the short service life of AVF. The results of Kaplan-Meier analysis showed that the service life of AVF in patients with diabetes was significantly shorter than that in MHD patients without diabetes (Log-rank χ2=13.191, P<0.001); the service life of AVF in patients with hypoalbuminemia was significantly shorter than that without hypoalbuminemia (Log-rank χ2=13.591, P<0.001). Conclusions:Diabetes mellitus and hypoalbuminemia are risk factors for the short service life of AVF. Therefore, intervention programs should be formulated to extend the service life of AVF.

Trace amines(TAs)are metabolically related to catecholamine and associated with cancer and neuro-logical disorders.Comprehensive measurement of TAs is essential for understanding pathological pro-cesses and providing proper drug intervention.However,the trace amounts and chemical instability of TAs challenge quantification.Here,diisopropyl phosphite coupled with chip two-dimensional(2D)liquid chromatography tandem triple-quadrupole mass spectrometry(LC-QQQ/MS)was developed to simul-taneously determine TAs and associated metabolites.The results showed that the sensitivities of TAs increased up to 5520 times compared with those using nonderivatized LC-QQQ/MS.This sensitive method was utilized to investigate their alterations in hepatoma cells after treatment with sorafenib.The significantly altered TAs and associated metabolites suggested that phenylalanine and tyrosine metabolic pathways were related to sorafenib treatment in Hep3B cells.This sensitive method has great potential to elucidate the mechanism and diagnose diseases considering that an increasing number of physiological functions of TAs have been discovered in recent decades.

Gestational diabetes mellitus (GDM) is common during pregnancy, with the prevalence reaching as high as 31.0% in some European regions (McIntyre et al., 2019). Dysfunction of the glucose metabolism in pregnancy can influence fetal growth via alteration of the intrauterine environment, resulting in an increased risk of abnormal offspring birth weight (McIntyre et al., 2019). Infants with abnormal birth weight will be faced with increased risks of neonatal complications in the perinatal period and chronic non-communicable diseases in childhood and adulthood (Mitanchez et al., 2015; McIntyre et al., 2019). Therefore, accurate estimation of birth weight for neonates from women with GDM is crucial for more sensible perinatal decision-making and improvement of perinatal outcomes. Timely antenatal intervention, with reference to accurately estimated fetal weight, may also decrease the risks of adverse long-term diseases.

OBJECTIVE:To evaluate the efficacy and safety of atomization inhalation of polymyxin combined in the adjunctive treatment for ventilator-associated pneumonia ,and to provide evidence-based reference for clinical treatment. METHODS : Retrieved from Cochrane Library ,Embase,PubMed,Web of Science ,CNKI,CBM,VIP and Wanfang database (from their inception to March 2021),randomized controlled trials (RCTs)about efficacy and safety of atomization inhalation of polymyxin combined with conventional treatment (trial group ) versus conventional treatment (control group ) for ventilator- associated pneumonia were collected. After data extraction and quality evaluation of included literatures met inclusion and exclusion criteria , Meta-analysis was performed by using Rev Man 5.4 software. RESULTS :A total of 13 clinical studies were included ,involving 2 RCTs and 11 cohort studies with a total of 1 066 patients. The results of Meta-analysis showed that clinical response rate [OR = 1.53,95%CI(1.17,2.00),P=0.002],microbial clearance rate [OR =1.46,95%CI(1.11,1.91),P=0.007] of trial group were significantly higher than those of control group ,with statistical significance. There was no statistical significance in the mortality rate [OR =0.88,95%CI(0.68,1.14),P=0.32] and the incidence of renal impairment [OR =1.04,95%CI(0.72,1.49),P=0.85] between 2 groups. CONCLUSIONS :Based on current evidence ,atomization inhalation of polymyxin combined with conventional treatment can significantly improve clinical response rate and microbial clearance rate of patients with ventilator- associated pneumonia. However , more strictly-designed , long-term follow-up and large-scale RCTs are needed.

Objective:To investigate the Correlation between ADC combined with serum C-reactive protein (CRP) and delayed encephalopathy after carbon monoxide poisoning (DEACMP), It provides scientific basis for early prediction of DEACMP.Methods:According to the design principle of case-control study, the data of acute carbon monoxide poisoning (ACOP) patients admitted to Shandong Provincial Hospital from December 2017 to December 2021 were retrospectively selected. Among them, patients with DEACMP were selected as the case group, without DEACMP were used as the control group. Univariate and multivariate analyses were performed on the two groups. Receiver operating characteristic curve (ROC) was used to evaluate the diagnostic efficacy of ADC combined with CRP as a combined predictor for disease.Results:A total of 89 patients with ACOP were included, including 33 patients with DEACMP and 56 patients without DEACMP. There were no significant differences in gender, age, smoking, drinking, and underlying diseases (hypertension, coronary heart disease) between groups ( P>0.05). Logistic regression analysis showed that white blood cell count (WBC) ( OR=1.64, 95% CI: 1.19-2.26, P=0.003), CRP ( OR=1.22, 95% CI: 1.03-1.45, P=0.019) and ADC value of central semiovale white matter ( OR=0.99, 95% CI: 0.98-1.00, P=0.010) were associated with DEACMP in patients with ACOP. The ROC curve results showed that the area under the ROC of ADC combined with CRP in the center of semiovale was 0.765 (95% CI: 0.656-0.845), the specificity was 87.9%, the sensitivity was 23.2%, and the cut-off value was 3.5°. Conclusions:WBC, CRP and ADC value of central semiovale are independent factors for DEACMP. ADC value of central semiovale combined with CRP has more clinical value in the early diagnosis of DEACMP. For ACOP patients with DEACMP triggering factors, the diagnosis and treatment awareness of early screening of brain magnetic resonance imaging should be strengthened to avoid DEACMP.

OBJECTIVES:
Psoriasis is a chronic inflammatory skin disease that affects adults and children. The most common subtype is psoriasis vulgaris. This article analyzes the characteristics and clinical features of children with psoriasis vulgaris to strengthen the understanding, treatment, and management for children with psoriasis.
METHODS:
A total of 208 children with psoriasis vulgaris, who were first admitted to the Department of Dermatology, Xiangya Hospital, Central South University from October 2012 to December 2018, were retrospectively analyzed. Their clinical characteristics, results of laboratory examination, treatment options and efficacy were summarized.
RESULTS:
The age of the 208 children with psoriasis vulgaris was (11.19±3.97) years old, the peak incidence was 12 years old, the disease duration was (27.46±31.30) months, and the male-female ratio was 1∶0.96. The most common site of the first attack was the scalp (37.98%), followed by the trunk (26.44%) and the limbs (22.12%). The causes leading to exacerbation were more common in infections and diets. There were 33 patients (15.87%) with a family history of psoriasis, showing the higher score of Psoriasis Area and Severity Index (PASI) and the higher Dermatological Quality of Life Index (DLQI) (both <0.05). In all patients, 29 cases (13.94%) were overweight, 19 cases (9.14%) were obese, and the rate of overweight and obesity in children with psoriasis vulgaris was higher than that of normal children in China. In the laboratory test, the serum levels of 25-hydroxyvitamin D (25-OH-VD) were decreased in most patients (47.5%), and the serum 25-OH-VD levels were found to be moderately negatively correlated with PASI score (<0.05). The score of DLQI in the patient was 5.56±3.57, the score of PASI was 7.25±6.83, and they were positively correlated (=0.409, <0.001). In most patients (72.11%), the severity of the disease was mild to moderate. Their treatment was often dominated by topical drugs and Chinese patent medicine (65.67%). Retinoids showed a good effect on children. Cyclosporine and methotrexate were effective in more severe cases.
CONCLUSIONS
Children with psoriasis vulgaris are mainly caused by infection and diet. Patients with family history have more serious illness, lower quality of life, and are more likely to have metabolic abnormalities such as overweight and obesity. The serum 25-OH-VD levels in children with psoriasis vulgaris are negatively correlated with the score of PASI.

The largest number of occupation was nurses (55.26%);the pharmacy department had the largest number (21.71%);working hours were mainly 8 h/day(84.21%);working years were the most less than 5 years(39.47%). 121 persons(39.80%)were aware of the potential hazards of occupational exposure to antineoplastic drugs,and 131 persons(43.09%)only knew a little about the Δ 项目基金:国家临床重点专科建设项目;四川省科研院所基本科 exposure hazards ;in PIVAS ,15 persons (71.43%) were 研业务项目(No.2018YSKY0017) *药师,硕士研究生。研究方向:临床药学。E-mail:370951417@ aware of the potential hazards of occupational exposure to qq.com antineoplastic drugs ,accounting the highest proportion among # 通信作者:主任药师,硕士生导师。研究方向:国家药物政策、药 all departments ; the proportion of technicians and other 事管理、医院药学。电话:028-87393436。E-mail:289302309@qq.com medical staff who did not know the occupational exposure 中国药房 2020年第31卷第8期 China Pharmacy 2020Vol. 31 No. 8 ·1009· hazard was the highest ,being 60%;the longer the total working time ,the higher the cognition degree of occupational exposure hazards (P=0.035 8). The most exposed antineoplastic drug was cyclophosphamide 165 persons(54.28%) and pemetrexed disodium 57 persons(18.75%)was the least. The total time of occupational exposure of medical staff in different departments was mainly short-term exposure ,among which the number of exposed persons in hematology department was the most (85.71%). 67 persons(22.04%)reported that they had physical discomfort after excluding the influence of other physical diseases ,mainly the increase of alopecia (73.13%);the propertion of medical staff who had physical discomfort in hematology department was the most(50.00%);the number of nurses who had physical discomfort (31.55%)was the most. 155 persons(50.99%)could not understand the antineoplastic drug protection measures ,41 persons (13.49%) had received relevant training ,108 persons (35.53%)understood the occupational protection of antineoplastic drugs. The highest level of awareness of protective measures was found among the medical staff in PIVAS ,and only 14.29% of the staff did not understand the protective measures. In term of occupation,the proportion of nurses who had received relevant training was the highest (19.05%). CONCLUSIONS :Medical staffs have a low level of knowledge about occupational exposure hazards and self-protection measures of antineoplastic drugs. The government should strengthen the construction of occupational protection regulations and standards for medical staff ;hospitals should strengthen internal management and attach great importance to the management of occupational protection in hospitals ; medical staff should increase awareness ,skills and reduce the risk of occupational exposure.
