Meanwhile oversight of radiation protection should be enhanced for individual radiation workers in Jiangsu province.

Objective To explore the effect of diammonium glycyrrhizinate(DG) and astragalus membranaceus (AM) injection on the clinical comprehensive score in patients with acute lung injury (ALI). Methods According to the random number table method,a prospective random controlled study was conducted in which 60 cases of patients with ALI were divided into a study group and a control group(each,30 cases). Both groups received a comprehensive treatment based on the new guidelines,and the study group was additionally given DG and AM injection(DG 150 mg+AM 20 ml)one time per day for 7 days. The scores of lung injury,acute physiology and chronic health evaluationⅡ(APACHEⅡ)and systemic inflammatory response syndrome(SIRS)were measured at baseline,3rd and 7th day after treatment,and ventilation support time and final disease mortality rate were also calculated in all the patients. Results There were no statistically significant differences between the two groups in the scores of lung injury,APACHEⅡand SIRS before treatment and after treatment for 3 days(all P>0.05),with prolonged treatment,the above indexes were significantly reduced compared with those before treatment in the two groups,and the decreases in scores of indexes in study group was more significant than those in control group after treatment(lung injury score:1.31±0.99 vs. 2.29±1.08,APACHEⅡscore:18.43±8.17 vs. 24.23±6.98,SIRS score:1.69±0.89 vs. 2.60±1.04,all P<0.01). The time(hour)for ventilator support in study group was shorter than that in the control group(176.10±57.81 vs. 286.07 ± 156.27,P<0.01),but there was no statistically significant difference in mortality rate between the two groups(13.33%vs.16.67%,P>0.05). Conclusion The results suggest that DG and AM injection improve the scores of lung injury,APACHEⅡand SIRS,and alleviate the lung injury,so that the injection is beneficial to the early weaning from the ventilator to support treatment in patients with acute lung injury,and has certain therapeutic effect on ALI.

Objective:To investigate the proper choice and improve the survival rate in neonates suffering from giant omphalocele (GO)with liver protrusion by analyzing the clinical characteristics, different treatments and outcomes.Methods:Neonates with GO admitted in Department of Neonatal Surgery in Wuhan Children′s Hospital were retrospected from January 2009 to May 2019.The treatment methods include: (1) repaired with similar silo-bag by staged operation; (2) one-stage repair with patch or not; (3) delayed repair by conservative treatment for some time (from 2 to 8 weeks) firstly.Data included gestational age, gender, birth weight, average diameter of omphalocele, contents of omphalocele, associated malformation, treatment method, duration of ventilator use and clinical outcome.These neonates were divided into 2 groups according to the contents of protrusion: group with liver protrusion and group with liver and other organs protrusion.Clinical data were summarized and compared between different groups.Results:Sixteen cases were collected, including 9 males and 7 females.The average age was (1.25±0.45) d (1-2 days), the average birth weight was (2.48±0.37) kg, and pregnant week was (36.23±1.17) weeks.The average diameter of the omphalocele was (9.88±3.30) cm, ranging from 5 cm to 15 cm.Seven cases were belonged to the group with liver protrusion, cases undergone one-stage repair, delayed repair were 6 cases and 1 case, respectively.There were 9 cases in group with liver and other organs protrusion, and the protruded organs included liver, intestine, colon or spleen.Among them, cases needed one-stage repair, delayed repair and silo-bag repair were 3 cases, 3 cases, 3 cases, respectively.Cases needed respiratory machine were 3 cases (42.8%) and 8 cases (88.89%) in group with liver protrusion and group with liver and other organs protrusion, respectively.Neonates had a longer time of needing respiratory machine in group with liver protrusion, comparing with the neonates in group with liver and other organs protrusion[(30.67±19.0) h vs.(106.25±69.36) h, P=0.021], and the risk rate to use respiratory machine was 5.143(95% CI: 0.727-36.368). There were no dead cases in group with liver protrusion.Three cases were dead in group with liver and other organs protrusion.All the patients were followed from 3 months to 4 years, and hernia in abdominal wall was found in 5 cases, including 1 case in group with liver protrusion and 4 cases in group with liver and other organs protrusion.If the dead cases had been excluded, the rate of hernia was 66.7% (4/6 cases) in group with liver and other organs protrusion. Conclusions:Individual treatment should be emphasized in neonates suffering from GO with liver protrusion.Neonates with single liver protrusion have a better prognosis than those with liver and other organs protrusion.One-stage repair is recommended in the former, and the delayed repair is highly recommended in the latter.The accessory liver should be considered when GO neonates presenting liver protrusion.

Objective To understand the variation in response of Oncomelania hupensis to niclosamide. Methods Snails were collected from 37 sampling areas distributed in 10 provinces (municipalities) using random environmental sampling methods in accordance with the different types and categories of snail habitats. In laboratory the snails were immersed in solutions of niclosamide for 24 and 48 hours at 25℃. Results 1.0 mg/L niclosamide showed 100% killing effect on snails in 24 hours. The LC 50 concentrations for snails immersed for 24 hours ranged from 0.0320 to 0.1689 mg/L with a mean value of 0.0920 mg/L. 0.5 mg/L niclosamide showed 100% killing effect on snails in 48 hours. The LC 50 values for snails immersed for 48 hours ranged between 0.0299 and 0.1114 mg/L with a mean of 0.0627 mg/L. There is a significant difference in snail sensitivity to niclosamide between sampling areas. Conclusion The sensitivity to niclosamide varied in snails from different sampling fields, but the chemical in a concentration of 1.0 mg/L showed 100% effect of killing snails, which is consistent to the manual of schistosomiasis control.

Objective To investigate the characteristics of Amyand's hernia (AH) in neonates in order to decrease the complications and to improve the prognosis.Methods Data about neonates with AH in Department of Neonatal Surgery,Wuhan Children's Hospital,Tongji Medical College,Huazhong University of Science and Technology,were collected from January 2010 to February 2017,and the AH cases published from 1997 to 2017 in PubMed and Wanfang Data were also reviewed.Results Twenty-two cases were collected,including 8 cases treated in Wuhan Children's Hospital,Tongji Medical College,Huazhong University of Science and Technology,and 14 cases from literature reports.In this group,4 cases underwent traditional operation and 4 cases underwent laparoscopy,respectively.All the patients underwent appendix resection and the ligation of the hernia sac.Among the 4 cases who underwent laparoscopic operation,contra-lateral hernia was found in 2 cases and pyocelia in 1 case.However,the appendix had a solid adhesion with the inguinal canal in those 4 cases and it was difficult to return the appendix to the cavity.Thus,the laparoscopy had to be terminated and the traditional procedure was carried out to separate the adhesion.In those 4 cases to whom the traditional operation was applied,1 case presented inflammation in abdomen and the contra-lateral hernia after operation.According to the pathological results of appendix,in this group,there were 3 cases,4 cases,and 1 case that presented Ⅱ,Ⅲ,Ⅳ type,respectively.In literature cases,there were 13 cases and 1 case that underwent traditional operation and laparoscopy,respectively.There were 4 cases,9 cases,and 1 case that presented Ⅱ,Ⅲ,Ⅳ type,respectively.The complications included located peritonitis (1 case),testicular torsion (1 case) and orchitis (1 case).All cases recovered smoothly.Conclusion Most of the AH cases in neonates present appendix suppuration,gangrene or perforation.The neonatal cases with AH also present obvious local infection and they are prone to develop into pyocelia in inguinal canal and abdominal cavity.In AH cases,laparoscopy has its own advantages,which not only help to make it clear if there is the contralateral hernia,but also helps to treat the complicated pyocelia in abdominal cavity,which help to avoid the residual infection efficiently.

Objective:To establish a good model of incomplete ablation of ectopic implanted tumor of liver, and explore the changes in the molecular landscape of residual cancer, cancer in nude mice.Methods:Eight immunodeficient BALB/c nude mice were used to establish an ectopic tumor model with the MHCC97-H hepatoma cell line, and they were randomly divided into experimental group and control group, with 4 mice in each group. The experimental group underwent simulated clinical incomplete ablation, and the control group only underwent false ablation. The differences between the models were evaluated by ultrasonic diagnostic equipment, thermal imaging cameras, HE staining and high-throughput whole transcriptome sequencing.Results:Liver cancer ectopic implantations in nude mices were all successful. The experimental group showed that the temperature of the tumor around the tip of the needle monitored by the thermal imaging camera was at 50-73.9 ℃. Compared with the control group, the HE staining of the experimental group mostly showed the coexistence of necrotic area-degeneration area-tumor cell area. The necrosis area was (23.75±13.77)%, and the degeneration area was 50%(30%). High-throughput whole transcriptome sequencing revealed that there were hundreds of overlapping stable molecular landscapes in the incomplete ablation simulation model both in vivo and in vitro.Conclusions:By establishing an ectopic implantion model of nude mice with incomplete ablation of residual liver cancer, it can provide a basis for studying the biological characteristics of incomplete ablation of residual cancer at the molecular level.

Objective:To evaluate the efficacy of the domestic D-Shant device for the treatment of patients with chronic heart failure (CHF) using echocardiography.Methods:Twenty-four CHF patients who were treated with domestic D-Shant device in Union Hospital, Tongji Medical College, Huazhong University of Science and Technology from September 2020 to December 2021 were enrolled in the study. Pulmonary capillary wedge pressure (PCWP)/ left atrial pressure (LAP), right atrial pressure (RAP), pulmonary artery pressure, interatrial septal gradient pressure, cardiac index and pulmonary/systemic blood flow ratio (Qp/Qs) were measured before and after implantation using right heart catheterization.Left atrial end-diastolic area index (LAEDAI), left atrial end-diastolic volume index (LAEDVI), left ventricular end-diastolic volume index (LVEDVI), left ventricular end-systolic volume index (LVESVI), left ventricular ejection fraction (LVEF), right atrial end-diastolic diameter, right ventricular end-diastolic diameter, tricuspid annular plane systolic excursion (TAPSE), right ventricular tractional area change (RVFAC), device shunt aperture, velocity and pressure, together with mitral and tricuspid regurgitation severity were measured using echocardiography before, and 1 month as well as 3 months after D-Shant device implantation. Clinical data were collected and analyzed including 6-minute walking test (6MWT), New York Heart Association (NYHA) classification and the Kansas City Cardiomyopathy Questionnaire (KCCQ). Spearman correlation analysis was used to determine the relation between the changes in PCWP/LAP as well as echocardiographic parameters before and 3 months after implantation and NYHA classification. Binary Logistic regression analysis was performed to determine the predictive factors of NYHA classification improvement at 3-month follow-up after D-Shant device implantation.Results:①D-Shant devices were successfully implanted in all patients. ②Compared with preoperative values, invasive PCWP/LAP systolic, diastolic and mean pressures, transatrial septal gradient, and pulmonary systolic, diastolic and mean pressures decreased significantly after implantation(all P<0.001); Qp/Qs increased significantly after implantation( P<0.001). ③Compared with preoperative values, TAPSE, RVFAC and pulmonary artery flow velocity increased at 1 month after implantation(all P<0.05), whereas a significant reduction in mitral regurgitation grade, and an increase in LVEF and pulmonary artery flow velocity at 3 months after implantation(all P<0.05). Right atrial end-diastolic diameter, right ventricular end-diastolic diameter, LAEDAI, LAEDVI, LVEDVI, LVESVI, ratio of early to late diastolic peak velocities of mitral inflow(E/A), systolic peak velocity of mitral annulus at septal site(S′), ratio of early diastolic peak velocity of mitral inflow to diastolic peak velocity of mitral annulus(E/e′), pulmonary artery diameter, inferior vena cava diameter and degree of tricuspid regurgitation did not change among before, and 1 month as well as 3 months after implantation. There were no significant changes in the device shunt aperture, velocity and pressure between 1 month and 3 months after implantation(all P>0.05). ④The significant improvements in NYHA classification, KCCQ scores and 6MWT were observed at 1 and 3 months after implantation compared with preoperative values (all P<0.01). ⑤NYHA classification at 3 months after implantation was correlated with LVEF pre-post, PCWP/LAP pre-post, TAPSE pre-post and RVFAC pre-post ( rs=0.738, -0.730, 0.738, 0.723; all P<0.001). Logistic regression analysis showed that LVEF pre-post was an independent predictor for NYHA classification improvement at 3 months after implantation ( OR=0.687, 95% CI=0.475-0.992, P=0.045) . Conclusions:Domestic D-Shant device can effectively improve the cardiac function and clinical symptoms in patients with CHF. Echocardiography is a feasible and effective method to evaluate the benefits of domestic D-Shant device for the treatment of CHF.
