A case of congenital laryngeal atresia of infraglottic type in a newborn infant is described for is rarity and importance of early diagnosis. This case was associated with tracheoesophageal fistula, and died in 5 minutes of life due to asphxia. Failure to intubate in the neonate should raise the possibility of laryngeal atresia and emergency management should be provided. The lung tissue was normally developing despite the complete obstruction of the outlet of the air and possible amniotic fluid passage.

OBJECTIVE:To establish a method for the dissolubility determination of Manidipine Hydrochloride tablet and eval-uate the quality consistency of generic and original preparation. METHODS:HPLC was performed on the column of Waters Sym-metry C18 column with mobile phase of potassium phosphate monobasic solution (potassium phosphate monobasic 6.8 g was well-mixed with water 1 000 ml,and pH was adjusted to 4.6 by potassium hydroxide solution)-acetonitrile (49∶51,V/V) at flow rate of 1.0 ml/min,detection wavelength was 228 nm,column temperature was 25℃,and the injection volume was 20μl. The dis-solution mediums were 0.1 mol/L hydrochloric acid solution,acetic acid-sodium acetate buffer solution(pH 4.0)and phosphate buf-fer solution [pH 6.8,adding into 0.5% sodium dodecyl sulfonate(SDS)],volume of dissolution medium was 900 ml and rotating rate was 50 r/min,and the dissolubility of Manidipine hydrochloride tablet generic and original preparation was investigated and the similarity of dissolution profile was evaluated by calculating similar factor (f2). RESULTS:The linear range of manidipine hydro-chloride was 0.625-20 μg/ml;RSDs of instrument precision and stability tests were lower than 2.0%;recoveries of 3 dissolution mediums were 92.86%-102.97%(RSD=1.9%,1.8% and 2.7%,n=9),respectively. The dissolubility of 3 batches of Manidipine hydrochloride tablet generic and original preparations was higher than 85% in 0.1 mol/L hydrochloric acid solution in 15 min;f2 was >50 in acetic acid-sodium acetate buffer solution (pH 4.0) and phosphate buffer solution (pH 6.8,adding into 0.5% SDS). CONCLUSIONS:The method is suitable for the dissolubility determination of Manidipine hydrochloride tablet;meanwhile,the dis-solution profile in vitro of Manidipine hydrochloride tablet generic and original preparations has similarities,so the quality consis-tency is good.

Objective To construct a scientific and feasible evaluation indicator system of health education effect of our country′s hospitalized patients with diabetes. Methods On the basis of literature review and semi-structured interview combined with group discussion, alternative index system were determined,and then the Delphi method were used for two round consultation with 30 diabetes experts to finally determine indicator evaluation system. Results Positive coefficient of the two rounds consultation were 86.7% (26/30) and 100.0% (26/26) respectively, experts′ authority coefficient was 0.889,and the Kendall W coefficients of concordance were 0.447,0.369 and 0.302 respectively (P<0.01). The evaluation indicator system of health education effect was consisted of 6 fisrt-level indicators, 24 second-level indicators and 55 third-level indicators. Conclusions The evaluation indicator system of health education effect is reliable and scientific, which can provide objective and quantitative standards for health education effect of hospitalized patients with diabetes in our country.

Objective:To understand the coronavirus disease 2019(COVID-19)prevention and control work and the problems and difficulties faced by non-government primary medical institutions in China during the epidemic period.Methods:A survey on the coronavirus disease 2019(COVID-19)prevention and control work of non-government primary medical institutions was conducted on April 14 to 21, 2020 with the self-designed questionnaire. The questionnaire contained three parts: the first part was basic information of medical staff in non-government primary medical institutions, including position and institutional information; the second part was the status quo of non-government primary medical institutions participating in the prevention and control of COVID-19, including the specific work and difficulties faced by the responders during the epidemic period; and the third part was the prevention and control effect of COVID-19 in the responders′ institutions, including whether there were confirmed cases and infected medical staff. An online invitation was issued among the members of General Practice Branch of Chinese Non-government Medical Institution Association. The invited participants included the heads, general practitioners and other medical personnel of the non-government primary medical institutions the invited participants voluntarily scanned the online two-dimensional code to fill in.Results:A total of 761 individuals in primary health institutions from 20 provinces, municipalities and autonomous regions in China participated in the survey. There were 290 (38.1%) men and 471 (61.9%) women with age of 40(32, 48) years; 83.0% (632/761) had worked for more than 5 years; 33.8% (257/761) owned primary professional titles and 33.0% (251/761) owned intermediate titles. Among all participants 28.5% (217/761) were general practitioners, 26.9% (205/761) were institutions/department managers, 14.6% (111/761) were specialists and 40.3% (307/761) were other related personnel. A total of 549 institutions continued to operate during the epidemic period and 96.5% (530/549) participated in the work related to the prevention and control of the epidemic, including prescreening and triage, health consultation, follow-up of suspected patients, donation, quarantine of suspected cases, follow-up of close contacts/discharged patients, diagnosis and treatment of patients with new coronavirus pneumonia. 44.7% (340/761) of respondents participated in the epidemic prevention as front-line staff and directly contacted patients/suspected patients, and 63.1% (480/761) participated in the epidemic prevention work of primary medical institutions, including clinical outpatient service, prescreening triage and screening. The working sites were not limited to the institutions, but also other sites including high-speed railway station. The 97.8% (744/761) responders expressed their willingness to participate in epidemic prevention work under the unified leadership and command of the state. The 63.9% (486/761) of the responders were worried about the lack of protective equipments and measures, and 90.4% (688/761) respondents showed that they needed medical supplies (protective equipment: masks, goggles, protective gowns, etc.).Conclusion:The participation of non-government primary medical institutions and their staff in COVID-19 infection prevention and control is a key component of the epidemic prevention process.
