Our country has made great achievements in organ transplantation,but there still exist many problems such as shortage of organs,seriously hindering the development of organ transplantation.Family factor,one of the influencing factors of organ transplantation in our country,has the characteristics of persistence and permanency.Researches on family factors will be helpful for the healthy development of organ transplantation.Started from family factors,this paper discussed the ethical issues of organ transplantation in our country and proposed appropriate measures such as changing moral cognition,advocating family support,strengthening community family intervention,correctly dealing with family ethics relationship,in order to provide a useful reference for the development of organ transplantation in China.

A cadmium column reduction-azo dyes spectrophotometric method based on micro sequential injection lab-on-valve was established for the determination of total nitrogen in seawater. The experimental parameters were optimized, and the interference experiment was carried out. The results showed that the interference of the main components and salinity in sea water could be eliminated by using a series of standard solution prepared by national standard seawater with certain salinity. The concentration of total nitrogen in seawater was linear with the absorbance in the range of 0 . 03-1 . 00 mg/L with a correlation coefficient of 0. 9993. When determining the national standard seawater at nitrogen concentration of 0. 20 mg/L, the relative standard deviation (RSD) was 4. 9%, the detection limit was 0. 010 mg/L, and the recoveries were 99. 5%-101 . 1%. There were not significance differences between the results of this method and national standard method in the t-test analysis. The method is suitable for the determination of total nitrogen in seawater.

Objective To assess the changes of right atrial size and mechanical function after radiofrequency catheter ablation in patients with paroxysmal atrial fibrillation using real-time threedimensional echocardiography(RT-3DE), and to study the correlation between the changes of left atrial(LA)and right atrial(RA) volume and function. Methods Thirty-five patients with paroxysmal atrial fibrillation were undergone radiofrequency catheter ablation (RFCA) successfully. Transthoracic echocardiography (TTE),tissue Doppler imaging(TDI) and RT-3DE were performed before, 1 month and 3 months after procedure respectively. Late systolic volume and area of RA and LA,ejection fraction(EF) of RA and LA,late diastolic peak velocity of mitral valve inflow, tricuspid valve inflow and late diastolic peak velocity of mitral annulus and tricuspid annulus were recorded. Results The 3DE images of all patients were satisfied.LA max area and 3DE LA max volume were significantly reduced at 1 months and 3 months after procedure compared with basic stage [ ( 18.8 ± 6.3) cm2 vs (21.5 ± 6.2) cm2 , (38.8 ± 17.0) ml vs (46.1 ± 20.0) ml,P ＜ 0.05]. 3DE LA EF also declined markedly at 1 month after RFCA, and restored at 3 months later compared with baseline [(41.1 ± 13.7) % vs (51.7 ± 15.9) %, (41.1 ± 13.7) % vs (45.6 ± 18.3) %, P ＜0.05]. The size and mechanical function of the right atrial after procedure were no obvious changes. There were no evidently correlation between the changes of LA and RA volume and function. Conclusions RT3DE can provide a precise method to quantify the value of atrial volume and function. The LA size and volume are significantly reduced after RFCA in patients with paroxysmal atrial fibrillation, however, the RA size and function are no obvious changes.

Objective To analyze the institutional cooperation networks of 137 military hospitals in terms of published papers, trends of cooperation and co-authorship in order to guide the cooperation between military hospitals.Methods The institutional cooperation, co-authorship, author-keyword co-occurrence and author-subject co-occurrence in the 137 military hospitals were analyzed with the Thomson data analyzer( TDA) software.Results and Conclusion The institutional coop-eration between military hospitals could be divided into 5 types and were based on the principle of proximity of locations and similiarity of research.The cooperaiton circle with Chinese PLA General Hospital as the center was expanded over time. The institutional cooperation between military and civilian hospitals was also based on the principle of proximity of locations and similiarity of research.Cooperation between productive authors mainly occurred in the same research group but co-au-thorship outside the research group was scarce.The potential competition or cooperation between research fields and authors can be analyzed by comparing co-authorship and author-keyword co-occurrence.

Objective:To evaluate and analyze the ultrasonic findings of idiopathic clubfoot and positional clubfoot deformities.Methods:Forty-nine newborn babies with congenital clubfoot were examined in the Department of Ultrasound of the Third Affiliated Hospital of Zhengzhou University from December 2020 to January 2022, Including 21 newborn babies(32 feet) with idiopathic clubfoot, and 28 babies(53 feet) with positional clubfoot. Twenty-two normal infants in the same period and the normal feet of the single clubfoot were selected as control group. The distance between medial malleolus and scaphoids of all feet were measured by ultrasound. The distance from the tangent line of the lateral edge of calcaneus to the midpoint of the lateral edge of the chondroid bone, medial soft tissue thickness and tibial calcaneal angle were measured by ultrasound. The data of idiopathic clubfoot group, positional clubfoot group and control group were statistically analyzed.Results:A total of 71 newborn babies with 142 feet were evaluated.The idiopathic clubfoot group had born and joint changes in the medial, lateral and posterior side, and the differences were statistically significant compared with the control group (all P<0.05). Compared with the control group, there were statistically significant differences in the medial and lateral side of the positional group(all P<0.05). But no significant changes in the posterior side( P>0.05). There were significant differences between medial and posterior side of idiopathic and positional clubfoot group (all P<0.05), but no significant differences in lateral side ( P>0.05). Conclusions:Ultrasonography can clearly display the tarsus bones in clubfoot, and observe the deformity changes of the idiopathic clubfoot and positional clubfoot.

Objective:To evaluate the deformity changes in the treatment of congenital clubfoot in infants by ultrasound, and to explore its clinical application value.Methods:Seventeen infants with congenital clubfoot treated in the Department of Pediatric Orthopaedics of the Third Affiliated Hospital of Zhengzhou University from March 2020 to June 2021 and 27 normal infants in the same period were selected. The distance between medial malleolus and scaphoids (MM-N distance) of all feet was measured by ultrasound. The distance from the tangent line of the lateral edge of calcaneus to the midpoint of the lateral edge of the chondroid bone (C-C distance), medial soft tissue thickness and tibial calcaneal angle were measured by ultrasound. The data before, after treatment and during follow-up were statistically analyzed.Results:A total of 88 feet of 44 infants were evaluated. The mean number of cast was 4.7±1.1, the follow-up time was (96.9±59.3)days. The MM-N distance, C-C distance and posterior tibial calcaneal angle in the clubfoot group were improved after treatment and at the last follow-up, and the differences were statistically significant (all P<0.01). During the treatment, 1 case had false correction, and 2 cases recurred in the last follow-up. Conclusions:Ultrasound can clearly display the medial, dorsal, lateral and posterior articular structures of normal and clubfoot, and can observe the deformity changes of clubfoot during the correction process, which can provide guidance for the clinical treatment of clubfoot.
