Purpose To characterize the alterations and significance of Rb in concurrent esophageal and gastric cardia precancerous lesions (dysplasia) from the same patients in Henan,a high-incidence area of esophageal carcinoma.Methods Rb protein expression was detected by the immunohistochemical staining (ABC method) in 30 patients with both esophageal and gastric cardia dysplasia in Henan area.Results Rb positive rates in esophageal epithelial dysplasia (EDYS) and gastric cardia dysplasia (GDYS) were 70% (21/30) and 80% (24/30), respectively, and the difference was not significant,(χ~2=0.800,P>0.05).However, there were 25 patients with Rb coincident changes in EDYS and GDYS from the same patient in 30 cases of esophageal and gastric cardia dysplasia (83%,25/30). The positive coincidence rate for Rb positive expression in EDYS and GDYS from the same patient accounted for 67% (20/30) and the negative coincidence rate was 17% (5/30) (Kappa=0.561,P<0.01).The significant relationship between Rb coincidence expression in EDYS and GDYS was found (P<0.01).Conclusions The high coincident alterations of Rb in EDYS and GDYS from the same patient indicate the possibility of similar molecular basis, which provides an important etiological clue for the similar geographic distribution and risk factors involved in esophageal squmaous cell carcinoma and gastric cardia adenocarcinoma.

We retrospectively analyzed and summarized the experience of observation and nursing care of 9 neonates with pleural effusions caused by peripherally inserted central catheter line insertion ( PICC ) infusion. All of the 9 neonates were with different degrees of shortness of breath, cyanosis, difficult breathing or frequent apnea. The exciting cause of pleural effusion was the shift of catheter tip of PICC which was confirmed by chest X-ray. The primary causes were the growth of height and limbs, positions, catheter maintenance and difficulties in catheter placement. The experience of nursing care included making neonates maintain natural positions during PICC infusion, closely observing patient′s condition especially for respiratory conditions, dynamically monitoring the change of position of catheter tip, timely notifying doctors of perfecting the related examinations of bedside sternum, ultrasonic and so on when patient′s condition changed, stopping the PICC infusion immediately when doubting that the changes of patient′s condition were related to PICC infusion, providing respiratory support for patients with respiratory dysfunction to improve respiratory function, assisting with thoracentesis or closed drainage of thoracic cavity when necessary to relieve the oppression. All of the 9 neonates were recovered and discharged hospital via active treatment.

Recently, the 2019 novel coronavirus (2019-nCoV) pneumonia outbroke in Wuhan and rapidly spread to all over China and even the world. Because of the strong infectivity and various clinical symptoms, it has brought certain difficulties to the epidemic prevention and control. Currently there is no specific drug for 2019-nCoV. Previous drugs used to treat other coronaviruses may be effective, but further clinical trials remain needed. We reviewed literature on the epidemiology, etiology, clinical manifestations, imaging manifestations, laboratory examination, diagnosis, complications, treatment and outcome of 2019-nCoV pneumonia.

Objective To characterise the alterations of serum autoantibodies for cyclinB1,p62,Koc-IMP1 and survivin in the subjects with esophgeal and gastric cardia carcinoma and precancerous lesion and their expres-sions in the esophageal and gastric cardia cancer tissue.Methods Enzyme-linked immunoassay and tumor-associated antigen mini-array (consisting of five full-length recombinant proteins,including eyefinB1-p62-Koc,IMP1 and Survivin)were applied to determine the serum level of the autoantibodies of these antigens on 376 subjects with e-sephageal and gastric cardia carcinoma and precancerous lesions.At the same time,the expression of these antigens was detected by immunohistochemical method(ABC)on 13 patients with esophageal cancer and 16 with gastric car-dia cancer.Results All of the 5 antigens determined,the linear correlation Was observed for the detection frequency of cyclinB1,IMPI and p62 in esophageal carcinogenesis,and for p62 in gastric cardia multi-stage progression from normal to precancerous and cancerous lesions(P<0.05).The detection rale with single positive antoantibody im-munoreactivity for both esophageal and gastric cardia cancers were low.However.the positive detection mte for both esophageal and gastric cardia cancer increased apparently when the multiple positive markers were combined together for analysis,which increased tO 3~5 and 3~4 folds respectively.Furthermore,the difference in autoantibody immu-noreactive rate was significant with the lesion progressed from mild tO severe precancerous lesions and to cancer both in esophageal and gastric cardia cancers(P<0.05).The positive immunoreactions of the 5 antigens were detected in cancer tissues.The positive immunostaining rates for cyclinB1,Koc,IMP1 and Survivin both in esophageal and gastric cardia cancers were higher compared to their serllin positive rate of autoantibodies I P<0.05).Of the pa-tients with positive immunostaining in the two cancer tissues,the autoantibodies in the serum for the corresponding antigens could be detected in the same patient.Conclusion The production of the tumor-associated autoantibodies is related tO antigens.The screening rate through serum tumor-associated antigen mini-array for the patients with e-sophageal and gastric cardia carcinoma and precancerous lesions has been increased apparently with combined analy-sis of multiple autoantibodies than with single one.
