Objective To investigate the N-terminal-pro-B-type natriuretic peptide (NT-proBNP) concentration in the difference myocardial wall motion after essential hypertension. Methods 326 patients with essential hypertension and normal heart function and 265 control subjects were measured with their NT-proBNP. According to Canau's categories, the ventricle geometries of patients with high left ventricular mass index were divided into 2 groups. Results NT-proBNP was significantly higher in patients with hypertension than in controls. After grouped by different myocardial wall motion, the patients with concentric hypertrophy were highest among all the groups; the groups with eccentric hypertrophy was secondly highest; concentric remodeling and normal geometric pattern were not significantly higher than the controls. Conclusion NT-proBNP is different in patients with different myocardial wall motion before heart failure, which may play an important role in myocardial remodeling.

Presently, there are many issues in traditional Chinese medicine (TCM) decoction, such as the uncertain sources of TCM, the lack of reminder for medication taboo, the nonstardard herb operation, and difficult supervision, etc. A digital service system of TCM decoction was established to solve the problems mentioned above. The digital service system mainly includes automatic coding for checking in & out, drug medication taboo database, digital operation in decoction, distribution through 2D code, the corresponding application for mobile phone, and the information supervision platform for TCM decoction. The digital service system of TCM decoction can track the quality & duty of the pieces, remind decoction medicine contraindications, improve the standard operation process of decoction, develop decoction distribution & tracking through cell phone, save the waiting time, and hence provides a new supervising method for TCM decoction. The digital service system of TCM decoction solves the key issues for the formula, operation, delivery and supervision of TCM. In the same vein, this system will expand the market share of TCM decoction and promote the development of TCM.

Objective To establish a serological detection method for EA-D-IgA antibody,and to evaluate its diagnostic efficacy for nasopharyngeal carcinoma in different clinical stage.Methods EA-D-IgA antibody serological detection method was established by using the polypropylene microplate with eukaryotic expression product of BMRF1 whole gene fragment of EB virus.Fifteen early stage (stage Ⅰ and Ⅱ) and 48 advanced (stage Ⅲ and Ⅳ) patients with nasopharyngeal carcinoma in Shanxi Provincial Cancer Hospital and Shanxi Dayi Hospital from April 2012 to August 2017,and serum samples from 40 patients with rhinitis who were treated at Shanxi Dayi Hospital from October 2016 to October 2017 were examined respectively by using the constructed EA-D-IgA antibody detection method.The positive detection rate of EA-D-IgA antibodies in different groups was calculated.When the patients with rhinitis were used as the differential control,the diagnostic efficacy of this index for different stages of nasopharyngeal carcinoma was evaluated.Results EA-D-IgA antibody serological method was successfully established.The positive detection rate of EA-D-IgA antibody in early nasopharyngeal carcinoma,advanced nasopharyngeal carcinoma and rhinitis control was 60.0 ％ (10/15),68.3 ％ (33/48) and 5.0 ％ (2/40) respectively.The differences between early stage nasopharyngeal carcinoma and the rhinitis control,advanced nasopharyngeal carcinoma and the rhinitis control were statistically significant (x2 =20.625,P =0.000;x2 =37.017,P =0.000).The difference between early nasopharyngeal carcinoma and advanced nasopharyngeal carcinoma was not statistically significant (x2 =0.394,P =0.530).When compared with the patients with rhinitis,the diagnostic sensitivity,specificity,positive predictive value,negative predictive value was 60.0 ％ and 68.3 ％,95.0 ％ and 95.0 ％,81.8 ％ and 94.3 ％,86.4 ％ and 71.7 ％ respectively in early nasopharyngeal carcinoma and advanced nasopharyngeal carcinoma.Conclusion The method constructed in this study effectively improves the efficacy of EA-D-IgA antibody detection in serological diagnosis of nasopharyngeal carcinoma,which can be used as an adjunct for early diagnosis of nasopharyngeal carcinoma,yet not as a reference for clinical staging.

A new system of blood flow block for control of bleeding in abdominal operation is composed of an abdominal magnetic blocking unit, an abdominal external electromagnet unit and other non-magnetic operation instrument. The abdominal external electromagnetic unit is placed in advance in the operation bed. The abdominal magnetic blocking unit can be placed directly on the ventral of the large vessels when need to blocking the abdominal large vessels during the operation. According to the non-contact suction characteristics of magnetic materials, the two magnetic units will attract each other and compression the vessels. Using this system for vascular occlusion does not need clear exposure and without separating vessel. There is the advantage of rapid, accurate and reliable for the system.

Objective To investigate the clinical efficacy of magnetic compression anastomosis for congenital esophageal atresia and stenosis.Methods The retrospective and descriptive study was conducted.The clinical data of 4 children who underwent magnetic compression anastomosis for congenital esophageal atresia and stenosis in the Northwest Women and Children's Hospital from December 2017 and February 2019 were collected.There were 2 males and 2 females.The children were aged 11 days,7 days,5 days,and 3 years,respectively.The children underwent magnetic compression anastomosis.Observation indicators:(1) surgical and postoperative situations;(2) follow-up.Follow-up using outpatient examination and telephone interview was performed to detect food intake and complications of children up to May 2019.Measurement data with normal distribution were represented as Mean±SD,and measurement data with skewed distribution were represented as M (range).Results (1) Surgical and postoperative situations:four children underwent magnetic compression anastomosis successfully.Of the 4 children,3 with esophageal atresia underwent open tracheoesophageal fistula repair and endoscopeassisted magnetic compression anastomosis,and 1 with congenital esophageal stenosis underwent endoscopic gastrostomy combined with magnetic compression anastomosis.The operation time of 4 children was (2.3±0.9) hours.The length of esophageal blind ending in the 3 children with esophageal atresia and length of esophageal stenosis were in the children with esophageal stenosis 30-35 mm and 8 mm.Four children has good magnet apposition,and time of postoperative magnet removal was (29± 10)days.Three children with esophageal atresia had oral removal of magnet,and 1 with esophageal stenosis had magnet removed by gastrostomy.One child complicated with postoperative fistula and anastomotic stenosis was cured by unobstructed drainage and nutritional support treatment.The duration of postoperative hospital stay was (39± 10)days.(2) Follow-up:4 patients were followed up for 3-17 months,with a median time of 10 months,and restored to oral intake after oral removal of magnet and removal of magnet by gastrostomy on the days 14-36 postoperatively.One child was detected anastomotic stenosis by esophagography at the postoperative 3 months,and was improved after esophageal dilatation.The other 3 children recovered to normal connectivity of esophagus postoperatively and maintain unobstructed.Four children had normal eating,without dysphagia or other serious complications.Conclusion Magnetic compression anastomosis is safe and feasible for congenital esophageal atresia and stenosis,with good short-term efficacy.
