Objectives: To investigated the safety and efficacy of treating patients with acute non-ST-segment elevation myocardial infarction (NSTEMI) and elevated levels of N-terminal pro-hormone B-type natriuretic peptide (NT-proBNP) with levosimendan within 24 hours of first medical contact (FMC). Methods: This multicenter, open-label, block-randomized controlled trial (NCT03189901) investigated the safety and efficacy of levosimendan as an early management strategy of acute heart failure (EMS-AHF) for patients with NSTEMI and high NT-proBNP levels. This study included 255 patients with NSTEMI and elevated NT-proBNP levels, including 142 males and 113 females with a median age of 65 (58-70) years, and were admitted in the emergency or outpatient departments at 14 medical centers in China between October 2017 and October 2021. The patients were randomly divided into a levosimendan group (n=129) and a control group (n=126). The primary outcome measure was NT-proBNP levels on day 3 of treatment and changes in the NT-proBNP levels from baseline on day 5 after randomization. The secondary outcome measures included the proportion of patients with more than 30% reduction in NT-proBNP levels from baseline, major adverse cardiovascular events (MACE) during hospitalization and at 6 months after hospitalization, safety during the treatment, and health economics indices. The measurement data parameters between groups were compared using the t-test or the non-parametric test. The count data parameters were compared between groups using the χ² test. Results: On day 3, the NT-proBNP levels in the levosimendan group were lower than the control group but were statistically insignificant [866 (455, 1 960) vs. 1 118 (459, 2 417) ng/L, Z=-1.25,P=0.21]. However, on day 5, changes in the NT-proBNP levels from baseline in the levosimendan group were significantly higher than the control group [67.6% (33.8%,82.5%)vs.54.8% (7.3%,77.9%), Z=-2.14, P=0.03]. There were no significant differences in the proportion of patients with more than 30% reduction in the NT-proBNP levels on day 5 between the levosimendan and the control groups [77.5% (100/129) vs. 69.0% (87/126), χ²=2.34, P=0.13]. Furthermore, incidences of MACE did not show any significant differences between the two groups during hospitalization [4.7% (6/129) vs. 7.1% (9/126), χ²=0.72, P=0.40] and at 6 months [14.7% (19/129) vs. 12.7% (16/126), χ²=0.22, P=0.64]. Four cardiac deaths were reported in the control group during hospitalization [0 (0/129) vs. 3.2% (4/126), P=0.06]. However, 6-month survival rates were comparable between the two groups (log-rank test, P=0.18). Moreover, adverse events or serious adverse events such as shock, ventricular fibrillation, and ventricular tachycardia were not reported in both the groups during levosimendan treatment (days 0-1). The total cost of hospitalization [34 591.00(15 527.46,59 324.80) vs. 37 144.65(16 066.90,63 919.00)yuan, Z=-0.26, P=0.80] and the total length of hospitalization [9 (8, 12) vs. 10 (7, 13) days, Z=0.72, P=0.72] were lower for patients in the levosimendan group compared to those in the control group, but did not show statistically significant differences. Conclusions: Early administration of levosimendan reduced NT-proBNP levels in NSTEMI patients with elevated NT-proBNP and did not increase the total cost and length of hospitalization, but did not significantly improve MACE during hospitalization or at 6 months.

This paper also makes a preliminary discussion on the construction of the training system of clinical pharmacists in the specialty of stomatology, so as to provide advice and references for the design and specific plan of the training system in the specialty of stomatology.

Objective: To analyze the gene mutation spectrum, clinical features, and the factors of disease progression and prognosis in patients with essential thrombocytosis (ET) . Methods: A retrospective analysis was conducted on 178 newly diagnosed ET patients admitted from February 1st, 2009 to November 1st, 2018. Results: Of the 178 patients, 89 were male and 89 female, and the median diagnosis age was 49.5 (3-86) years old. JAK2V617F, CALR and MPL mutations frequencies were 16.45% (1.67%-43.90%) , 40.00% (10.00%-49.15%) and 25.10% (25.00%-40.00%) , respectively. Compared with patients with CALR mutations, patients with JAK2V617F mutation had higher diagnosis age (P=0.035) , higher white blood cell count (P=0.040) , higher hemoglobin concentration (P=0.001) , and lower platelet count (P=0.002) , respectively. Of them, 47 patients (27.01%) developed thrombotic events before diagnosis, and 3 ones (1.72%) experienced thrombotic events after diagnosis. Multivariate analysis revealed age >60 years (P=0.013, OR=4.595, 95%CI 1.382-15.282) and cardiovascular risk factors (CVF) (P<0.001, OR=8.873, 95%CI 2.921-26.955) as risk factors for thrombotic events, CALR mutation (P=0.032, OR=0.126, 95%CI 0.019-0.838) as a protective factor for thrombotic events. Age >60 years (P=0.042, OR=4.045, 95%CI 1.053-15.534) was found to be a risk factor for the overall survival (OS) of ET patients. OS of age ≤60 years and age>60 years were calculated by Kaplan-Meier analysis to be (115.231±1.899) months and (83.291±4.991) months (χ²=6.406, P=0.011) , respectively. Conclusion Age>60 years and CVF were risk factors for thrombotic event. CALR mutation was a protective factor for thrombotic event. Age >60 years was a risk factor for OS in ET patients.

Objective: To investigate the effect of hypertensive disorder complicating pregnancy (HDCP) on the mortality and early complications of premature infants. Methods: The general clinical data of preterm infants with gestational age 24-36^{+ 6} weeks were collected from the cooperative units in the task group from January 1, 2013 to December 31, 2014.According to the severity of HDCP, the infants were divided into 4 groups: HDCP group, preeclampsia group, eclampsia group and non HDCP group, the mortality and major complications of preterm infants were compared, and the influencing factors were analyzed. Results: The mortality rate of preterm in the HDCP group was significantly higher than that of non HDCP group, and there was statistical significance (χ²=9.970, P=0.019). Eclampsia had a highest fatality rate (4.8%) in the early stage, compared with non HDCP group (2.2%), and the difference was statistically significant.Comparison of HDCP group (1.8%) and eclampsia group (3.2%) suggested that there was no statistically significant difference.The incidence of respiratory distress syndrome (RDS) in preterm in HDCP group was significantly higher than that of non HDCP group, and there was statistical significance (χ²=13.241, P=0.004). Eclampsia group showed the highest incidence (35.4%), compared with non HDCP group (16.2%), the difference was statistically significant, but compared with HDCP group (19.9%), preeclampsia group (17.1%), there was no significant diffe-rence.The incidence of bronchopulmonary dysplasia (BPD) in preterm in HDCP group was significantly higher than that of non HDCP group (χ²=9.592, P=0.022), the highest incidence showed up in eclampsia group (9.7%), compared with non HDCP group (2.0%) and HDCP group (1.7%), the difference was statistically significant.But there was no statistically significant difference, compared with preeclampsia group.As the degree of HDCP aggravated, the incidence of BPD gradually rose.There was no significant impact on necrotizing enterocolitis (NEC), retinopathy of prematurity (ROP), intraventricular hemorrhage (IVH) and sepsis of HDCP (χ²=7.054, 7.214, 0.358, 3.852; P=0.070, 0.065, 0.949, 0.278). Considering the overall outcome of the child, that was, whether the child died or survived, he had at least one complication, and HDCP had an effect on it (χ²=15.697, P=0.001), so the incidence increased while the degree of HDCP rose gradually.After adjusting gestational age, birth weight, sex, way of delivery, placental abruption and front placenta, prenatal hormonal, gestational diabetes, neonatal asphyxia and other factors, the results displayed that HDCP was the factor leading to the death of premature baby (OR=2.159, 95%CI: 1.093-4.266), and comparison between preeclampsia and eclampsia showed no statistical difference (P=0.714, 0.389); HDCP had no significant influence on RDS, BDP, ICH, NEC, ROP and sepsis. Conclusions HDCP leads to increased risk of premature death, but also leads to the increased incidence of RDS and BPD, but it had no obvious effect on NEC, ROP, IVH, sepsis and other complications.

OBJECTIVETo investigate the effect of premature rupture of the membrane (PROM) on neonatal complications in premature infants.

METHODSThe registration information of 7684 preterm infants with gestational age <37 weeks were collected from the cooperative units in the task group between January 1, 2014 to December 31, 2014. Specially trained personnel from each cooperative units filled in the unified form in a standardized format to record the gender, gestational age, birth weight, PROM, placental abruption, antenatal corticosteroid, Apgar score, amniotic fluid pollution, and complications of the infants. The data were analyzed comparatively between the cases with PROM and those without (control).

RESULTSThe preterm mortality rate was significantly lower but the incidences of ICH, NEC, ROP and BPD were significantly higher in PROM group than in the control group (P<0.05). The 95% confidence interval of the OR value was <1 for mortality, and was >1 for ICH, NEC, ROP and BPD. After adjustment for gestational age, birth weight, gender, mode of delivery, placental abruption, placenta previa, prenatal hormones, gestational diabetes mellitus (GDM), gestational period hypertension and 5-min Apgar score <7, the incidences of NEC, ROP and BPD were significantly different between the two groups (P<0.05) with 95% confidence interval of OR value >1, but the mortality rate and incidence of ICH were not significantly different between the two groups (P>0.05).

CONCLUSIONPROM is a risk factor for NEC, ROP and BPD in preterm infants, and adequate intervention of PROM can reduce the incidences of such complications as NEC, ROP and BPD in the infants.

OBJECTIVE: To analyze the relationship between the high-temperature working classification and prevalence of hypertension in iron and steel production workers. METHODS: By a convenience sampling method,2 798 workers in an iron and steel production enterprise were selected as study subjects. They were divided into high-temperature working group( 1 070 cases) and non-high-temperature working( control) group( 1 728 cases). The occupational health status was investigated by questionnaire survey and the blood pressure was measured. The wet bulb globe temperature in workplace of high temperature working group was measured,and the high-temperature classification was made based on the time of exposure to high temperature. RESULTS: The prevalence rate of hypertension of 2 798 iron and steel production workers was32. 8%. The prevalence rate of hypertension of high-temperature working group was higher than that of the control group( 41. 3% vs 27. 5%,P < 0. 01). The prevalence rate of hypertension in high temperature working group presented an increasing tendency with the increase of high-temperature working level( P < 0. 01). The multiple logistic regression analysis results showed that excluding the confounding factors of age,body mass index,family history of hypertension,educational background,smoking,alcohol drinking,salt intake and mental stress,it showed that high-temperature working classification was positively correlated with increasing prevalence of hypertension in high-temperature working group( P <0. 01); and the initial exposure age to high-temperature was negatively correlated with the prevalence of hypertension in iron and steel production workers( P < 0. 01). CONCLUSION: High-temperature is an important influence factor to the prevalence of hypertension in iron and steel production workers. Strengthening the management of high-temperature classification is helpful for the prevention and treatment control of hypertension in the iron and steel production workers

OBJECTIVETwo children with hydroa vacciniforme-like lymphoma (HVLL) were reported for a better understanding of this disease.

METHODSThe clinical manifestation, pathological characteristics, therapeutic outcomes of two children with HVLL were analyzed and presented by compared with what described in literatures.

RESULTSTwo children were girls, who treated firstly in the hospital in May 2012, July 2012 and their duration were 1 years, more than 10 years respectively. Their clinical manifestations were both limbs and craniofacial polymorphous rashes. Pathological findings revealed that the dermis and subcutaneous tissue were profiled by atypical lymphocytic infiltration. Immunohistochemistry showed that the infiltration of cells from T/NK cell, and Epstein-Barr virus encoded small RNA (EBER)(+). Case 1 was treated with chemotherapy, but her condition continued to deteriorate. Case 2 just received symptomatic treatment, her skin lesions gradually reduced and rash disappeared completely 2 months later.

CONCLUSIONHVLL is found with special clinical manifestation, its diagnosis mainly depend on skin biopsy and immunohistochemistry, there is no specific treatment method now, and its prognosis still needs further research.

Objective To analyze the genetic characteristics of the complete sequence of coxsackievirus A24 variant(CA24v) isolated from acute hemorrhagic conjunctivitis (AHC) outbreaks in Zhejiang province during 2002 to 2010.Methods Complete sequences of CA24v epidemic strains isolated in different years were amplified under the RT-PCR assay,while the sequences of whole genome,VP1,and 3C region of Zhejiang strains were compared with epidemic strains isolated in other areas of China and abroad.Results The whole genome of Zhejiang CA24v strains isolated in 2002 and 2010 was 7456-7458 bp in length,encoding a polyglutamine protein which containing 2214 amino acid residues.There was a insertion with T on site 97 and 119 within 5' non-coding region between epidemic strain Zhejiang/08/10 and strains isolated in 2002.The rates of amino acid homology among Zhejiang/08/10 and other strains isolated since 2002 were between 94.7％ and 100.0％.Compared with the representative strains circulated within the recent 60 years,the largest average amino acid variations had been occurred on region 2A and 3A,with the ratios as 8.4％ and 7.3％ respectively.The smallest variation happened in region 3D,with the ratio only as 1.9％.The rates of stable amino acid variation on the whole genome between strains isolated since 1987 and 2002 were 38 and 20.P-distance within groups appeared that region 3C was more stable than VP1 of strains isolated in 2002-2010,and the 3D of early strain Jamaica/10628/87 might have had a nature of recombination but not observed on those epidemic strains in recent years.Conclusion Within the evolution of CA24v strains,the time course was more significant than the geographical differences.There had been sporadic epidemics of AHC caused by CA24v in Zhejiang province since 2002.

Objective To study the relative factors of relapse in children with aplastic anemia (AA) treated with antithymocyte globulin(ATG) combined with cyclosporine.Methods A retrospective analysis of the risk factors of relapse in children with AA after response to immunosuppressive therapy(IST).All patients received IST from Jan.2007 to Dec.2011 in the First Affiliated Hospital of Zhengzhou University.IST:ATG 3 mg/(kg · d) × 5 d,cyclosporine 5-8 mg/(kg · d).Results (1) The basic cure rate was 29.4％ (25/85 cases),remission and obvious progress rate was 47.0％ (40/85 cases),and 20 cases were ineffective,the overall incidence of remission was 76.5％ (65/85 cases),basic cure,remission and obvious progress were considered as effective.The relapse rate was 12.3％ (8/65 cases).(2)Relapse was relative with cyclosporine concentration,infections episodes.And it was not relative with severity of disease,age,sex,duration of AA prior to initial treatment,severity of response.Conclusions A significant proportion of patients subsequently relapsed and required second-line therapy.Early IST,long-time continuation-maintenance of cyclosporine and the reduction of infectious episodes are important to prevent relapse.

OBJECTIVETo evaluate the efficacy and safety of endoscopic mucous resection with transparent cap (EMR-Cap) and endoscopic multi-band mucosectomy (MBM) in the treatment of early esophageal cancer and precancerous lesion.

METHODSA retrospective study was performed to review 30 EMR-Cap cases from December 2008 to December 2009 and 32 MBM cases from January 2010 to January 2011 of early esophageal cancer and precancerous lesions. The differences between these two techniques in efficacy, safety, and cost were compared.

RESULTSIn EMR-Cap group, the median resection time was 26(10-56) min and median procedure time was 43(22-81) min, significantly longer than those in MBM group [10(7-18) min and 32(28-45) min, P=0.036 and 0.038, respectively]. There were no significant differences between the two groups in total thickness and depth of resected lesions (P>0.05). In EMR-Cap group, the median cost was significantly higher than that of MBM group [(5466±354) vs. (4014±368) RMB, P=0.008)].

CONCLUSIONSEMR-Cap and MBM are minimally invasive, safe and effective methods in the treatment of early esophageal cancer and precancerous lesions. Compared to the EMR-Cap, MBM is simple with shorter treatment time and lower cost.
