Objective To Compare postoperative complications between patients with varicose veins of the lower limbs treated with foam sclerotherapy or endovenous laser.Method From 2011 to 2015,simple varicosis of great saphenous vein patients (grade C3-6) in 2 542 cases,3 468 limbs were divided into 2 groups.Combined with high ligation of great saphenous vein plus stripping,foam sclerotherapy group (1 355 cases) underwent calf foam sclerotherapy (1％ polidocanol),endovenous laser group (1 187 cases) underwent endovenous laser therapy.All postoperative patients were treated with stretch socks for 3 months.Postoperative pain (calf),deep vein thrombosis,pulmonary embolism,superficial thrombophlebitis,saphenous nerve injury,ecchymoma,migraine,allergic dermatitis,pigmentation in 2 groups were compared.Result During the follow-up,28 cases in foam sclerotherapy group had saphenous nerve injury (2％),1 071 (79.1％) cases had subcutaneous ecchymosis,613 cases (51.6％) in endovenous laser group had saphenous nerve injury,979 cases (82.5％) had subcutaneous ecchymosis,8 cases (1.0％) had skin burns (x2 =824.660,4.786,9.161,P ＜ 0.05).Endovenous laser group (23.8％) was significantly better than that of foam sclerotherapy group (30.8％) in pigmentation (x2 =15.243,P ＜0.05).Conclusion Treatment of varicose veins of the lower leg with foam sclerotherapy has less postoperative complications compared with endovenous laser.

OBJECTIVETo survey the treatment status and clinical features of hospitalized patients with acute myocardial infarction (AMI) of 13 hospitals in Beijing in 2005.

METHODSUniform questionnaires were used to register AMI patients hospitalized from January 1 to December 31, 2005 in the 13 hospitals including traditional Chinese medicine (TCM) hospitals (n = 6) and western medicine hospitals (WM, n = 7) from Beijing. A total of 1663 AMI patients were registered (1366 cases in WM hospitals and 297 cases in TCM hospitals). An Access database was established and patient information was input, the clinical features and treatment status of hospitalized AMI patients were analyzed.

RESULTSThe mean age was (63.9 +/- 12.8) years old [(62.8 +/- 12.8) years for WM Hospitals and (69.1 +/- 11.8) years for TCM hospitals, P < 0.05], male to female ratio was 2.4:1 (2.7:1 for WM hospitals and 1.6:1 for TCM hospitals, P < 0.05). The median time to hospital was 14 hours in TCM hospitals and 11 hours in WM hospitals (P > 0.05). Incidences of history of cerebrovascular disease, high blood pressure, diabetes, hyperlipidemia and complications such as in-patient arrhythmia, cardiac insufficiency, cardiogenic shock were significantly higher in TCM hospitals than in WM hospitals. The total mortality of 1663 AMI cases was 8.2% (15.8% in TCM hospitals vs. 6.6% in WM hospitals, P < 0.01). The reperfusion rate including emergency PCI and thrombolytic therapy rate was 31.3% in 13 hospitals (33.3% in WM hospitals vs. 21.9% in TCM hospitals, P < 0.05). Percent of guideline recommend drug use for AMI was as follows: aspirin 93.6%, ACEI and ARB 85.1%, beta-blocker 78.7%, low molecular weight heparin 85.4%, statins 74.7%.

CONCLUSIONSReperfusion therapy and guideline recommended drugs were widely used although there was a need for further improvement. The hospitalized mortality showed a downward trend compared with results from five years ago, patients in TCM hospitals had an independent clinical features.

Objective:To evaluate the effect of laryngopharyngeal reflux on sedation-related adverse events in the patients undergoing painless gastroscopy.Methods:Two hundred and eighty-nine American Society of Anesthesiologists physical status Ⅰ-Ⅲ patients of both sexes, aged 18-75 yr, with body mass index 18.5-28.0 kg/m 2, scheduled for elective painless gastrocopy, were selected.Specimens of glottic secretions before and after gastroscopy were collected, and the concentration of human pepsin was measured by enzyme-linked immunosorbent assay.The patients in whom the concentration of pepsin was positive before the examination were excluded (the concentration ≥ 31.34 pg/ml was considered as positive). The patients were divided into laryngopharyngeal reflux group (R group, the concentration of pepsin was positive after gastroscopy) and non-laryngopharyngeal reflux group (N group, the concentration of pepsin was negative after gastroscopy) according to the concentration of pepsin in the secretion samples before and after gastroscopy.The occurrence of hypoxemia, hypotension, bradycardia, bucking and body movement during operation was recorded.The patients were followed up by telephone on the 1st, 3rd and 7th days after operation.The sore throat, hoarseness, nausea and vomiting, cough and expectoration and use of antibiotics were recorded. Results:Compared with group N, the incidence of bucking and hypoxemia was significantly increased, the incidence of sore throat and hoarseness was increased on the 1st day after operation, and the incidence of cough and expectoration was increased on the 1st and 3rd days after gastroscopy in group R ( P<0.05). Conclusion:Laryngopharyngeal reflux can increase the development of intraoperative and postoperative sedation-related adverse events in the patients undergoing painless gastroscopy.

OBJECTIVETo explore the appropriate strategies which are suitable for the areas with diverse health and economic resource settings in China by estimating the life outcomes and cost-effectiveness of several cervical cancer screening strategies.

METHODSMarkov model was used to calculate the long-term effectiveness, utility, benefit and cost among screened and unscreened cohorts in rural and urban areas, and then analyses of cost-effectiveness, cost-utility and cost-benefit were performed. The assessed screening strategies were acetic acid of visual inspection combined with Lugol's iodine staining (VIA/VILI), conventional Pap smear and simple HPV DNA testing (careHPV) in rural areas, and conventional Pap smear, simple HPV DNA testing (careHPV), HPV DNA testing (HC2) and liquid-based cytology (LBC) alone or combined with HPV DNA testing (LBC+HC2) in urban areas. We estimated the life outcomes and cost-effectiveness of the above screening strategies at one-year, 3-year and 5-year intervals.

RESULTSAll of the screening strategies were effective to decrease cervical cancer mortality and to increase life years, with a trend of shorter screening interval having better effectiveness. However, no matter in urban or rural areas, compared with careHPV testing at 5-year interval, the costs of other screening strategies were 1.28 - 13.86 folds, 1.31 - 14.14 folds, and 1.27 - 12.80 folds higher to avoid one death, to save a year of life, and a QALY, and the benefit per cost of other screening strategies was 9.9%-90.2%.

CONCLUSIONScareHPV testing at 5-year interval has the best cost-effectiveness performance and the highest benefit-cost ratio with the moderate life outcomes. It is the optimal cervical cancer screening strategy to be generalized in our country. careHPV testing at 3 years interval can be considered in more developed areas to achieve better effectiveness.

Objective:To analyze the risk factors of bronchopulmonary dysplasia(BPD)in very preterm infants(VPI), and to provide scientific basis for the prevention and treatment of BPD in VPI.Methods:A prospective multicenter study was designed to collect the clinical data of VPI in department of neonatology of 28 hospitals in 7 regions from September 2019 to December 2020.According to the continuous oxygen dependence at 28 days after birth, VPI were divided into non BPD group and BPD group, and the risk factors of BPD in VPI were analyzed.Results:A total of 2 514 cases of VPI including 1 364 cases without BPD and 1 150 cases with BPD were enrolled.The incidence of BPD was 45.7%.The smaller the gestational age and weight, the higher the incidence of BPD( P<0.001). Compared with non BPD group, the average birth age, weight and cesarean section rate in BPD group were lower, and the incidence of male infants, small for gestational age and 5-minute apgar score≤7 were higher( P<0.01). In BPD group, the incidences of neonatal respiratory distress syndrome(NRDS), hemodynamically significant patent ductus arteriosus, retinopathy of prematurity, feeding intolerance, extrauterine growth restriction, grade Ⅲ~Ⅳ intracranial hemorrhage, anemia, early-onset and late-onset sepsis, nosocomial infection, parenteral nutrition-associated cholestasis were higher( P<0.05), the use of pulmonary surfactant(PS), postnatal hormone exposure, anemia and blood transfusion were also higher, and the time of invasive and non-invasive mechanical ventilation, oxygen use and total hospital stay were longer( P<0.001). The time of starting enteral nutrition, cumulative fasting days, days of reaching total enteral nutrition, days of continuous parenteral nutrition, days of reaching 110 kcal/(kg·d) total calorie, days of reaching 110 kcal/(kg·d) oral calorie were longer and the breastfeeding rate was lower in BPD group than those in non BPD group( P<0.001). The cumulative doses of amino acid and fat emulsion during the first week of hospitalization were higher in BPD group( P<0.001). Multivariate Logistic regression analysis showed that NRDS, invasive mechanical ventilation, age of reaching total enteral nutrition, anemia and blood transfusion were the independent risk factors for BPD in VPI, and older gestational age was the protective factor for BPD. Conclusion:Strengthening perinatal management, avoiding premature delivery and severe NRDS, shortening the time of invasive mechanical ventilation, paying attention to enteral nutrition management, reaching whole intestinal feeding as soon as possible, and strictly mastering the indications of blood transfusion are very important to reduce the incidence of BPD in VPI.

OBJECTIVES: To investigate the incidence of extrauterine growth retardation (EUGR) and its risk factors in very preterm infants (VPIs) during hospitalization in China. METHODS: A prospective multicenter study was performed on the medical data of 2 514 VPIs who were hospitalized in the department of neonatology in 28 hospitals from 7 areas of China between September 2019 and December 2020. According to the presence or absence of EUGR based on the evaluation of body weight at the corrected gestational age of 36 weeks or at discharge, the VPIs were classified to two groups: EUGR group (n=1 189) and non-EUGR (n=1 325). The clinical features were compared between the two groups, and the incidence of EUGR and risk factors for EUGR were examined. RESULTS: The incidence of EUGR was 47.30% (1 189/2 514) evaluated by weight. The multivariate logistic regression analysis showed that higher weight growth velocity after regaining birth weight and higher cumulative calorie intake during the first week of hospitalization were protective factors against EUGR (P<0.05), while small-for-gestational-age birth, prolonged time to the initiation of total enteral feeding, prolonged cumulative fasting time, lower breast milk intake before starting human milk fortifiers, prolonged time to the initiation of full fortified feeding, and moderate-to-severe bronchopulmonary dysplasia were risk factors for EUGR (P<0.05). CONCLUSIONS It is crucial to reduce the incidence of EUGR by achieving total enteral feeding as early as possible, strengthening breastfeeding, increasing calorie intake in the first week after birth, improving the velocity of weight gain, and preventing moderate-severe bronchopulmonary dysplasia in VPIs.
