Returning to its commonweal feature and enhancing impartiality are the focal purposes of Chinese new healthcare reform in the near future.Rawl's theory of justice could explain the past difficulties and indicate the intending complications in the forthcoming innovation.We can see the selfishness of human nature from Rawl's Veil of Ignorance.People's greed will bring about such deadweight to national finance that the goal of the reform has to be inclined to efficiency,which forms again a seasonal movement.

This article discussed on the ethical problems in human stem cell research.It asserted:The essence of its ethical quarrel in stem histiocyte research is the social impartiality in the distribution of scarce health resources,while the sticking point of the human crisis in embryonic stem cell research is the problems on the status and right for the embryos.It pointed out that the ethical principles of life sciences shand be newly constituted.

Objective To observe the clinical curative effect and the serum CPR changes by the treatment principle of Yangyin-Huayu for the patients with recurrent hemoptysis of Bronchiectasis. Methods A total of 64 patients were enrolled and divided into 2 groups according to the random number table method, 32 patients in each group. The control group was treated with the injection of blood clotting enzyme, pituitrin, levofloxacin lactate. And the treatment group was treated with the Yangyin-Huayu on the basis of the control group. Two groups were treated for 10 days. The CPR was detected by the double optical path immune turbidity analyzer. And the clinical effects, symptoms and signs scores were compared between before and after treatment and between two groups. Results Compared with the total effective rate of control group 84.38%(27/32), the treatment group was 96.88% (31/32) and significantly high (χ2=6.372, P<0.01). After treatment, the levels of serum CPR (2.45 ± 1.42 mg/L vs. 6.19 ± 2.34 mg/L, t=4.671) in the treatment groupwas significantly lower than that in the control group (P<0.01). The scores of cough (0.62 ± 0.91 vs. 1.34 ± 0.58, t=5.364), sputum (0.14 ± 0.28 vs. 0.68 ± 0.72, t=4.035), haemoptysis (0.10 ± 0.65 vs. 0.62 ± 0.26, t=5.012), fever (0.04 ± 0.31 vs. 0.76 ± 0.07, t=3.026), breathing difficulties (0.12 ± 0.41 vs. 0.69 ± 0.05, t=4.010) in the treatment group were lower than those in the control group (P<0.01). Conclusions The treatment principle of Yangyin-Huayu combined with conventional western medicine therapy can improve the patients with recurrent hemoptysisin the fields of symptoms, signs, the serum level of CPR, and total effect rates.

The germination of medical ethics could date back to as early as the 15th century BC or even earlier.This subject successively takes on three theoretical forms possessing diverse peculiarities.The first stage could be called Classical Theory of Medical Morality,or Pre-Medical Ethics,with evident character of virtue ethics and deontology.The second stage is the traditional medical ethics.As a relatively mature theoretical system,it takes on the characteristics of meticulous,standardization,specialization,humanity and legislation.The third stage might be called the international medical ethics,whose prominent trait is the birth,progress and grandness of Modern Bioethics.

Objective To assess the relationship between gastric carcinoma perfusion imaging parameters with the multislice spi-ral CT (MSCT)and the tumor angiogenesis(MVD,VEGF).Methods (1)33 patients with gastric cancer were carried on perfusion CT scanning in the suspected lesions,and compared with operation and histological result.MSCT perfusion parameters tumor,such as local blood flow (BF),blood volume (BV),mean transit time of contrast agent (MTT),permeability surface (PS),were recor-ded,and compared with clinical pathological data.(2)27 patients of 33 cases which CT perfusion plane matching with operation pa-thology specimens performed with tumor microvessel density (MVD),vascular endothelial growth factor (VEGF)monoclonal anti-body immunohistochemical examination of MVD,the most intensive areas of high power (×200 HP)field counted,and VEGF stai-ning positive judged.Results Achievement ratio of gastric carcinoma MSCT perfusion imaging was 84.85% (28/33).The average value of BF,BV,MTT and PS were 63.658 ± 18.305,7.5 1 1 ± 2.427,1 1.952 ± 4.325 and 31.81 7 ± 13.533,respectively,and MVD was 37.7 ± 11.1/200 HP (range:13-60).VEGF was positive in 16 cases,negative in 11 cases.Gastric carcinoma undifferentiated group perfusion parameter PS value (35.1 5 ± 12.74 )and MVD (40.53 ± 10.66 )were higher than the differentiation group (23.90 ± 12.71 and 31.13 ± 9.82 )(P < 0.05 ),but BF,BV,MTT not statistically significant;Differences of CT perfusion parameters and MVD were not significant statistically between invasive serosa and noninvasive ;PS value (36.65± 12.80)of lymph node metastasis was greater than without metastasis(22.70 ± 1 1.1 5 )(P <0.01 ),the other was no significant difference;TNM staging Ⅲ,Ⅳ phase group of BF value (69.56 ± 1 6.49),PS value (34.90 ± 12.80)and MVD value (40.74 ± 10.53)were higher than Ⅰ,Ⅱ Group (49.63 ± 1 5.04),(24.50 ± 13.13)and (30.63 ± 9.61)(P <0.01).Spearman correla-tion analysis in confidence (two tails)of 0.01 was statistically significant between MVD in tumor tissues and gastric cancer MSCT perfusion parameters of BF (r=0.404)and MTT (r=0.371),whereas BV and PS were no significance.The regression equation of MVD with BF and MTT:MVD =1 6.602+0.1 50XBF +0.967XMTT,model checking of F values was 6.62,P =0.003.Conclusion The gastric carcinoma multi-slice CT perfusion imaging parameters BF,MTT and MVD,VEGF(+)was positive correlation, MSCT perfusion imaging parameters reflects tumor VEGF positive expression of gastric carcinoma.

Objective To investigate the effectiveness and safety of peritoneal dialysis(PD) in premature infants with acute renal failure(ARF).Methods In the neonatal intensive care unit (NICU) of Guangdong Province Maternal and Children Hospital, 12 premature infants underwent continuous PD due to ARF from March 2012 to March 2015, without using any antibiotics in the dialysis fluid.Before and after dialysis, the changes of serum urea nitrogen, creatinine, potassium and pH were compared.The complications (blockage, leakage, infection and necrotizing enterocolitis) and gastrointestinal nutrition situation were observed.Wilcoxon signed rank sum test was used for statistical analysis.Results Among the 12 premature infants, the underlying causes of ARF were sepsis (n=9), perinatal asphyxia (n=2), twin twin transfusion syndrome (n=l).The average gestational age was (30.9±3.2) weeks, the average body weight (before PD) was (1 461 ±525) g, the duration of PD was (3.8±2.6) d.Complications associated with PD included leakage (n=3) and peritonitis (n=2) in which Candids albicans and Klebsiella pneumonia were identified in ascites.Gastrointestinal nutrition was built up in six cases within one to four days after dialysis, among which one developing necrotizing enterocolitis on the 7th d after feeding.Finally, eight babies died (six died after initiative discontinued treatment and two died because of critically illness) and four patients were cured and discharged.Lower serum urea nitrogen and potassium levels and higher pH value were shown after dialysis than before [(9.16 ± 3.15) vs (12.71 ±6.98) mmol/L;(4.36±0.82) vs (6.24± 1.72) mmol/L;7.32±0.17 vs 7.21 ±0.17;Z=-2.118,-2.197 and-2.981, all P ＜ 0.05).Conclusion PD is an alternative safe and effective treatment for premature infants with ARF due to its simplicity both in manipulation and equipment requirement.

Objective To compare the clinical efficacy,adverse reactions,and management effect of postoperative intravenous analgesia for patients with postoperative intravenous analgesia with digital information technology and electronic analgesia pump system.Methods Totally 100 patients with postoperative intravenous analgesia (PCIA) were selected from April 2015 to September 2015 with postoperative intravenous analgesia and randomly divided into Wireless analgesic pump system Group (A group) and electronic analgesia pump group (group B),n =50 each group.Pain score (NRS),sedation score (OAA/S),comfort score (BCS),the total number of times and the number of effective press were pressed in patients were observed and compared between two groups after postoperative analgesia 1 hour (T0),4 hour (T1),10 hour (T2),16 hour (T3),and 24 hour (T4).Patients with early adverse reactions,patients and ward medical staff satisfaction,pain pump failure found in the medical staff and effective treatment of adverse events were also observed and compared in two groups.Results There were no significant difference of patients with NRS,OAA/S and BCS in two groups (P ＞ 0.05).Adverse reactions after postoperative analgesia,total number of times and the number of effective press had also no significant difference in two groups (P ＞ 0.05).Two groups of patients with air blockage,incomplete analgesia rate of adverse events was not significantly different (P ＞ 0.05).Medical workers in time [(1.0 ± 0.5) min vs (3.0 ± 2.1) min,P ＜ 0.05],effective processing time [(4.0-± 2.1) min vs (8.0 ± 5.1) min,P ＜ 0.05] in group A was significantly shorter than group B.The patient satisfaction in group A was significantly higher than group B(12.0 ± 4.2 vs 9.0 ± 3.1,P ＜ 0.05).The satisfaction degree of medical staff in group A was also significantly higher than group B(13.0 ±3.1 vs 10.0 ±2.1,P ＜0.05).Conclusions The digital information technology of wireless analgesic pump is applied to postoperative analgesia for medical workers to standardize management,improve the work efficiency,and increase the satisfaction of patients and medical staffs.

Objective To explore the surgical treatment strategy for tibial pilon fractures.Methods Forty-seven patients with tibial pilon fractures surgically treated in our hospital from May 2005 to March 2008 were retrospectively studied. There were 37 males and ten females, at mean age of 42 years (range 23-46 years). There were 51 sides of tibial pilon fractures, for four patients were with bilateral tibial pilon fractures. Injury causes included traffic accidents in 34 patients, fall from height in 12 and bruise by heavy objects in five. Open fractures were determined in seven patients and close fractures in 44 patients. According to Ruedi-Allgower classification, there were six sides of type Ⅰ fractures, 28 type Ⅱ fractures and 17 type Ⅲ fractures. According to Tscherna-Grotzen tissue injuries classification,open fractures were determined as 1° in two patients, 2° in three and 3° in two; close injuries were defined as 0° in two patients, 1° in 27 and 2° in 15. Distal tibia was partitioned as anterolateral column,anteromedial column and posterior column in order to select reasonable internal fixation. Eighteen fractures were treated with DePuy T plate, 10 with AO cloverleaf pattern plate, two with AO small T plate,two with locking plate, four with Link anterolateral anatomic plates and 15 with Orthofix overtake-anklejoint outside-fixed frame combined with limited internal fixation. Results The patients were followed up for a mean time of 23 months (range 12-44 months). According to Mazur ankle evaluation grading system, 29 patients were graded as excellent, 13 good, seven fair and two poor, with an excellence rate of 82.4%. Conclusions Correct operation time and treatment plans on the basis of Ruedi-Allgower classification and Tscherne-Gotzen classifications of soft tissues and reasonable internal fixation according to the condition of the involved three column in distal tibia can decrease postoperative complications and achieve good and satisfactory clinical effect.

Objective: To investigate the factors influencing the development of gastric cancer in Chinese populations, so as provide insights into creating a model for predicting gastric cancer incidence among Chinese populations. Methods: The case-control and cohort studies pertaining to factors affecting the development of gastric cancer were retrieved in electronic Chinese and English databases, including CNKI, Wanfang Data, VIP, PubMed, Web of Science and Embase from their inception until September 30, 2021. A meta-analysis was performed using R package version 4.1.0. Sensitivity analysis was performed using the “leave-one-out” evaluation procedure, and the publication bias was evaluated using the Egger regression test and the trim-and-fill procedure. Results: A total of 5 301 publications were screened and 116 eligible studies were included in the final analysis, including 103 case-control studies and 13 cohort studies, which covered approximately 3.23 million study subjects. A total of 45 factors affecting the development of gastric cancer were collected, and there were less than 4 publications reporting 7 factors, which were only qualitatively described. There were 38 factors included in the final meta-analysis. A total of 21 factors were identified as risk factors of gastric cancer, including a history of gastrointestinal diseases (pooled OR=4.85, 95%CI: 3.74-6.29), H. pylori infection (pooled OR=3.18, 95%CI: 2.35-4.32), binge eating and drinking (pooled OR=2.88, 95%CI: 2.09-3.97) and a family history of tumors (pooled OR=2.78, 95%CI: 2.17-3.56), and 10 factors as protective factors, including vegetable intake (pooled OR=0.48, 95%CI: 0.38-0.61), tea consumption (pooled OR=0.55, 95%CI: 0.47-0.64), administration of aspirin (pooled OR=0.53, 95%CI: 0.31-0.92) and administration of statins (pooled OR=0.59, 95%CI: 0.44-0.80). Sensitivity analyses of eating moldy food frequently, white meat intake, favoring spicy food and administration of sulfonylureas were not robust. Following correction with the trim-and-fill procedure, there was still a publication bias pertaining to high income, diabetes, administration of stains, alcohol consumption, tea consumption and white meat intake. Conclusions The development of gastric cancer is associated with a medical history of gastrointestinal disease, H. pylori infection, family history of tumors and poor dietary habits. Risk and protective factors of gastric cancer are recommended to be included in models used to predict gastric cancer incidence among Chinese populations.

Objective To review the surgical methods and mid-term results of mitral valve repair in pediatric patients with moderate to severe mitral regurgitation (MR).Methods 132 children with moderate to severe MR,aged (18.9 ± 7.2)months,weighted(11.3 ±4.8) kg.The etiology for mitral regurgitation is congenital heart disease in 126 cases,infective endocarditis in 5 cases and Marfan syndrome in 1 case.Mitral valvuloplasty(MVP) was performed with cardiopulmonary bypass under moderate systemic hypothermia.The methods of MVP included annuloplasty,annuloplasty ring,cleft closure,reconstruction of posterior leaflet.The coucomitant cardiac anomalies were treated at the same time.The results of repair were evaluated by saline injection test and transesophageal echocardiography (TEE) during operation.Results Intra-operative TEE results: 131 cases had none to mild MR,and only one case had moderate MR.The patient underwent second repair immediately,subsequent TEE was mild.Mean cardiopulmonary bypass (CPB) time was (80.0 ± 31.1) minutes.Mean aortic clump time was (48.0 ± 17.9) minutes.The in-hospital mortality was 2.3％ (3 cases died).One died of heart failure on postoperative day 7,the other died of low cardiac output syndrome resulting on postoperative day 2.Another one was large ventricular septal defect(VSD) with pulmonary hypertension (PH),died of pulmonary infection.Mean postoperative ventilation time was (34.4 ± 31.9) hours,and mean postoperative inhosptial time was (9.0 ± 5.4) days.The average follow-up period was (40.5 ± 8.3) months (2 to 74 months).122 cases were fully followed up.Echocardiography showed that moderate MR was in 7 patients,and 3 patients had severe MR.4 patients underwent re-do mitral valve repair or mitral valve replacement.There was no late death.The overall survival rate at 5 years was 97.7％ and the overall freedom from reoperation at 5 years was 92.0％.Conclusion Pediatric patients with moderate to severe MR need early surgical treatment,the early and mid-term results were satisfactory.Individualized treatment protocol based on specific pathology was the keypoint of surgical therapy.
