Network management of health record is an important measure to realize the aim of equalization of the basic public health services.Nowadays,a lot of ethical hidden dangers have been left when most areas of our country doing the job of network management of health record,such as,violating the citizen rights of privacy and informed consent,impairing citizen rights of autonomy and health,lacking of balance mechanism between the individual interest and public benefit,and so on.In this paper,these phenomena are considered based on ethical rules,and suggestions centred around the improving of trust valuations between doctors and patients,information technology,medical moral education and the setting up of related laws for improvement have been provided.

Objective To compare the development of gastric insufflation related to different peak inspiratory pressures (PIPs) during facemask ventilation in the pediatric patients.Methods Ninety male pediatric patients,aged 2-4 yr,of American Society of Anesthesiologists physical status Ⅰ,scheduled for elective surgery under general anesthesia,were randomly divided into 5 groups (n =18 each) using a random number table:PIP 8 cmH2O group (group P8),PIP 10 cmH2O group (group P10),PIP 12 cm H2O group (groupP12),PIP 14cmH2O group (group P14) and PIP 16 cmH2O group (group P16).Anesthesia was induced with fentanil,propofol and rocuronium in sequence.After loss of eyelash reflex,positive pressure facemask ventilation was performed for a 120 s period in pressure-controlled mode.Gastric insufflation was detected by real-time ultrasonography of the antrum,and cross-sectional antral area was measured using ultrasonography before facemask ventilation and at 120 s of facemask ventilation.The pulse oximetry (SpO2),tidal volume (VT),end-tidal pressure of carbon dioxide (PETCO2) and end-tidal oxygen concentration (ETO2) were recorded at 30,60,90,and 120 s of facemask ventilation.The development of gastric insufflation and hypoventilation was recorded.Results Compared with group P8,the incidence of gastric insufflation was significantly increased in group P16 (P＜0.01),and no significant change was found in the incidence of gastric insufflation in the other groups (P＞0.05),the incidence of hypoventilation was significantly decreased,VT and ETO2 were increased,and PET CO2 was decreased in P12,P14 and P16 groups,and PETCO2 was significantly decreased at 120 s of facemask ventilation (P＜ 0.05 or 0.01),and no significant change was found in the other parameters in group P10 (P＞0.05).Compared with P12 and P14 groups,VT was significantly increased,PEHTCO2 was decreased at 120 s of facemask ventilation (P＜0.05),and no significant change was found in the incidence of hypoventilation and ETO2 in group P16 (P＞0.05).There was no significant difference between group P12 and group P14 in the incidence of hypoventilation,VT,PETCO2 and ETO2 (P＞0.05).The pediatric patients showed a certain CO2 accumulation [PETCO2 (40.6±4.0) mmHg] at 120 s of facemask ventilation in group P8,and the pediatric patients showed excessive ventilation [PETCO2 (23.6± 1.4) mmHg],and cross-sectional antral area was not measured using ultrasonography in three cases because of excessive gastric insufflation in group P16.Conclusion PIP at 12-14 mmHg in pressure-controlled ventilation mode can not only ensure adequate preoxygenation and but also avoid excessive gastric insufflation during facemask ventilation in the pediatric patients.

Objective To investigate the role of ATP￣binding cassette ( ABC ) family on the resistance of nasopharyngeal carcinoma (NPC) stem cells (CSCs) to cisplatin. Methods We compared the differences between the drug extravasation capability of CNE￣2 and CNE￣2S by using Rhodamine￣123 efflux assay. We determined the mRNA and protein expression levels of ABC transport family members, including ABCA3,ABCB1,ABCB5,ABCC1,ABCC2 and ABCG2,after 48 h being treated with 1 μmol.L-1 cisplatin by RT￣PC and Western blotting.Rhoamine￣123 efflux and apoptosis by cisplatin in two kinds of cells was examined by ABCA3 gene silencing with specific small￣interfering RNA. Results The IC50 of cisplatin on CNE￣2S was 4.1 fold to that on CNE￣2(P<0.05).For the relative drug effluent activity and Na+K+ ATPase activity,CNE￣2S was 4.8 fold to CNE￣2(P<0.05),suggested that CNE￣2S expressed more ABCA3,ABCB1,ABCC1 and ABCG2 in comparison to CNE￣2(P<0.05).After 48 h treatment with 1 μmol.L-1 cisplatin,ABCA3 specifically highly expressed in CNE￣2S (P<0.05), and knocking down of ABCA3 resulted in reduction of rhodamine￣123 efflux and increase of apoptosis. Conclusion The cisplatin resistance of NPC CSCs is associated with enhanced expression of ABCA3,ABCC1 and ABCG2, suppression of ABCA3 could reverse the resistance of NPC CSCs to cisplatin.

Objective To investigate the way that nasopharyngeal carcinoma (NPC) and NPC stem cells develops resistance to cisplatin through anti-reactive oxygen species mechanism. Methods Using CCK-8 cell counting kit, we measured the half inhibitory concentration of cisplatin against NPC cellsCNE-2and NPC stem cellsCNE-2S, and compared their resistant index. We examined the differences in the reactive oxygen species (ROS) levels, total glutathi?one (GSH) levels, and total superoxide dismutase (SOD) levels between CNE-2 and CNE-2S at different concentrations of cisplatin administration (0.1,0.5 and 1.0μmol·L-1). Using q-PCR, we determined the mRNA expression level of GSS, GCLC, GCLM, SOD1 and SOD2 after 48 hours administration of cisplatin at 1 μmol · L-1. Protein expression level of SOD2 was also tested using Western Blot after 48 hours administration of cisplatin at 1μmol · L-1. Upon silencing the SOD2 in NPC cell through siRNA, Trypan blue was used to analyze cell survival after cisplatin was administrated at 1μmol · L-1. Results The inhibition concentration of cisplatin against CNE-2 was higher than that against CNE-2S (μmol · L-1:9.8 ± 1.1 vs 2.4 ± 0.6,P<0.05). ROS levels in CNE-2 and CNE-2S both rise with cisplatin administration, but ROS levels of CNE-2 before and after cisplatin treatment were both higher than those in CNE-2S (P<0.05). The total gluta?thione levels in CNE-2 and CNE-2S were both increased after 1μmol·L-1 cisplatin treatment but there is no significant dif?ference in levels of glutathione between these two cell lines. After treated with cisplatin, SOD level were increased in both CNE-2S and CNE-2, but it is higher in CNE-2S than that in CNE-2 (P<0.05). The mRNA levels of GSS, GCLC, GCLM, and SOD1 were not different significantly between in CNE-2 and in CNE-2S with or without cisplatin treatment. However, SOD2 in CNE-2S were higher than that in CNE-2 on both mRNA and protein levels (P<0.05). Silenced SOD2 disrupted the resistance of cisplatin in CNE-2S. Conclusion These data suggest that NPC stem cells (CNE-2S) enhance its drug re?sistance to cisplatin through highly expression of SOD2 which posed anti-ROS capacity.

Objective To systematically evaluate the effects of mechanical chest compression (CC) combined with manual CC and single-manual CC on the outcome indexes of cardiopulmonary resuscitation (CPR) for patients with in-hospital cardiac arrest (IHCA). Methods The relevant publicly published literatures about the effects of mechanical CC combined with manual CC and single-manual CC on the outcome of CPR were searched by using the following Chinese keywords for retrieval: "cardiac arrest, asystole, sudden death, artificial recovery, artificial press, artificial CC, unarmed CPR, unarmed resuscitation, unarmed compressions, unarmed chest compressions, unarmed, artificial, resuscitation instrument, resuscitation machine, resuscitator, CPR, LUCAS, Autopulse, Thumper, MSCPR-1A"in databases such as China Biomedical Literature (CBM), VIP, Wanfang, and China National Knowledge Internet (CNKI) from their dates of foundation to March 11, 2019, and using the following key words in English "heart arrest, cardiac arrest, cardiopulmonary arrest, Cardiopulmonary Resuscitation, Resuscitation, Cardio-Pulmonary Resuscitation, CPR, compression, mechanical, automatic, automated, load distributing band, LBD, Autopulse, LUCAS" to retrieve all the published articles especially concerning the topics on the application effects of mechanical combined with manual CC for IHCA patients' CPR in the America National Library database (PubMed), Excerpta Medica (EMbase), Web of Science, and Cochrane Library from the establishment of the databases to March 11, 2019. The indexes of outcomes included return of spontaneous circulation (ROSC) rate, survival rate after hospital discharge and incidence of complications. The literatures were extracted independently by two reviewers, the qualities of the included randomized controlled trials (RCTs) were evaluated according to the Cochrane bias risk assessment tool, and the qualities of the included observational studies were evaluated according to the literature quality assessment form (NOS). Meta analysis was performed by using RevMan 5.3 software, and publication bias was assessed by using funnel plot. Results Twenty-one studies were enrolled, including 11 RCT articles and 10 observational studies; there were 2 005 participants. The results of this Meta-analysis showed that compared with manual CC, the ROSC rate and after discharge survival rate of IHCA patients were obviously higher in combined CC group [ROSC: odds ratio (OR) = 2.50, 95% confidence interval (95%CI) = 2.03-3.09, P < 0.000 01; discharge survival rate: OR = 2.71, 95%CI = 1.91-3.85, P < 0.000 01]; the incidence of complications of combined CC was lower than that in single manual CC (OR = 0.30, 95%CI = 0.13-0.68, P = 0.004). The funnel plots indicated that there was no apparent bias in the ROSC; because the enrolled studies were relatively few, it was difficult to evaluate the symmetrical characteristics of the funnel plots for discharge survival rate and the complication rate. Conclusions For IHCA patients, combined CC can improve ROSC, discharge survival rate, and reduce the occurrence of complications. It is suggested that during the actual rescue of IHCA patients, it is better to use combined CC, that is to say, manual CC should be adopted immediately in the early stage and then replace the mechanical CC device as soon as possible.

Objective To comprehensively evaluate and compare the resuscitation efficacy of chest-compression-only cardiopulmonary resuscitation (CCPR) and standard cardiopulmonary resuscitation (SCPR) for patients with out-of-hospital cardiac arrest (OHCA). Methods Databases such as PubMed, Embase, Ovid, Cochrane Library, Wanfang, CNKI, VIP, CBM were searched from the date of their foundation to March 2nd 2018, and the studies on the difference of effects between CCPR and SCPR for patients with OHCA were retrieved. The outcomes included the return of spontaneous circulation (ROSC) rate, survival to hospital discharge, neurological function completion rate. Two reviewers independently screened the literature meeting the inclusion criteria, independently collected information and evaluated the literature quality. Meta-analysis was conducted using RevMan 5.3 software, and sensitivity analysis was conducted by selecting model analysis method and removing single research method. Funnel plot was used to evaluate publication bias. Results A total of 10 cohort studies were included, including 174 163 patients with OHCA, of which 95 157 undergone CCPR and 79 006 undergone SCPR. The scores of the Newcastle-Ottawa scale (NOS) were 8-9, indicating that the quality of the literatures included was high. It was shown by the Meta-analysis that CCPR had the higher rate of survival to hospital discharge [relative risk (RR) = 1.04, 95% confidence interval (95%CI) = 1.00-1.08, P = 0.04] and neurological function completion (RR = 1.11, 95%CI = 1.06-1.17, P < 0.000 1) than SCPR, but there was no significant difference in ROSC rate between the two groups (RR = 1.01, 95%CI = 0.98-1.04, P = 0.52). In the subgroup, there was no statistical significance between CCPR and SCPR in the rate of survival to hospital discharge in cardiac OHCA patients (RR = 1.13, 95%CI = 0.82-1.57, P = 0.45). However, in non-cardiac OHCA group, SCPR showed more benefits than CCPR in improving the rate of survival to hospital discharge (RR = 0.88, 95%CI = 0.80-0.96, P = 0.004). The above analysis results were consistent in the fixed effect model and random effect model, indicating that the results were reliable and stable. It was shown by the funnel plot that most of the studies were left-right inverted funnel type, indicating a low publication bias. However, the bias could not be completely excluded due to the small number of included literatures. Conclusions For patients without OHCA etiological classification, CCPR was not less than SCPR in improving ROSC rate, discharge survival rate and good neurological function, and CCPR was more advantageous in learning and the willingness of bystanders to implement. However, when non-cardiogenic OHCA could be identified, SCPR should be recommended when conditions permit.

OBJECTIVE: To delineate the clinical and genetic features of a fetus with micrognathia, low-set ears, microtia, polyhydramnios and anechoic stomach by ultrasonography. METHODS: Whole exome sequencing (WES) was carried out to detect genetic variant in the fetus, for which routine chromosomal karyotyping and chromosomal microarray analysis (CMA) yielded no positive finding. Candidate variants were verified by Sanger sequencing and bioinformatic analysis. RESULTS: WES revealed that the fetus has carried a de novo nonsense c.2302C>T (p.Q768X) variant in exon 23 of the EFTUD2 gene, which was detected in neither parent. The variant was unreported previously and may lead to premature termination of the translation of EFTUD2 protein at the 768th amino acid. Bioinformatic analysis predicted the amino acid to be highly conserved and may alter the structure and function of the EFTUD2 protein. CONCLUSION The c.2302C>T variant of the EFTUD2 gene probably underlay the mandibulofacial dysostosis Guion-Almeida type in the fetus. Discovery of the novel variant has enriched variant spectrum of the EFTUD2 gene and provided a basis for genetic counseling and prenatal diagnosis for the family.

Chest compressions are a key component of cardiopulmonary resuscitation (CPR). The determination of the optimal compression point (OCP) in adult CPR is an indispensable critical factor for high quality chest compressions (CCs). At present, the OCP for adult CPR is still controversial, which still needs further research and discussion. To provide theoretical reference for determining the OCP, this paper reviews the research progress of the OCP of adult CPR from the development process of compression point and hemodynamic mechanism, so as to improve the quality of CCs and the outcome of cardiac arrest (CA) patients.

Objective:To investigate the management of patients with intravenous misplacement of nephrostomy tube following percutaneous renal surgery.Methods:The data of 6 patients with intravenous misplacement of nephrostomy tube during percutaneous nephrolithotomy (PCNL) treated in the two hospitals of Chenzhou from January 2006 to December 2020 were retrospectively analyzed. The median age was 41.0(38.5, 53.0) years old. There were 4 males and 2 females. Three patients had undergone contralateral upper urinary tract operation. One patient had undergone ipsilateral upper urinary tract operation. Two patients had not undergone upper urinary tract operation. Two of the 6 patients had a solitary kidney. Two patients were diagnosed with staghorn calculi (combined with mild hydronephrosis in 1 patient, moderate hydronephrosis in 1 patient). Four patients were diagnosed with ureteral calculus (combined with mild hydronephrosis in 2 patients, moderate hydronephrosis in 1 patient, severe hydronephrosis in 1 patient). In all 6 patients, the tract was dilated with fascial dilators. Immediately after dilator removal, brisk venous bleeding was noted. A nephrostomy tube was inserted promptly through the sheath to tamponade the tract and was immediately closed. Five cases were diagnosed by CT after operation, and 1 case was early diagnosed by intraoperative injection of contrast medium through nephrostomy tube. The nephrostomy tube was misplaced in 5 patients with left upper urinary tract calculi, and in 1 patient with right upper urinary tract calculi. The tip of nephrostomy tube was located in ipsilateral renal vein in 3 patients with left upper urinary tract calculus, inferior vena cava in 2 patients with left upper urinary tract calculus, and contralateral renal vein in 1 patient with right upper urinary tract calculus. No venous thrombosis of renal vein or inferior vena cava was founded in the 6 patients. All 6 patients were managed with strict bed rest, intravenous antibiotics, and one-step or two-step tube withdrawal under close monitoring. One step method referred to total removal of nephrostomy tube under ultrasonic monitoring. Two step method referred to retracting the end of nephrostomy tube into the renal sinus under CT monitoring in the first step, then the nephrostomy tube was completely removed under ultrasound monitoring.Results:All 6 patients were successfully managed with strict bed rest, intravenous antibiotics, and one-step or two-step tube withdrawal under close monitoring. The tube was withdrew by one-step method in 1 patient, by two-step method in 5 patients. The original operations were performed successfully under close observation in 4 patients during the same hospitalization and in 1 patient during the next hospitalization. Other type of operation in 1 patient was performed during the next hospitalization. The all 6 patients were discharged uneventfully. The stone was cleared.Conclusions:Intravenous misplacement of a nephrostomy tube is mainly diagnosed by CT. The nephrostomy tube should be sealed immediately after diagnosis. The intravenously misplaced nephrostomy tube can be successfully removed by one-step or two-step withdrawing under close monitoring. Upper urinary tract stones can be successfully treated at the same time or by stages.
