Objective To evaluate the myocardial protective effect of hyperpolarized arrest induced with ATP-sensitive potassium channel opener ,pinacidil in vitroMethods Twenty-four rabbit hearts were randomly divided into three groups : hypothermic hyperpolarized group (LH group), normothermic hyperpolarized group ( WH group), and hyperkalemic control group (group C) The isolated rabbit hearts with a Langendorff apparatus were perfused oxygenated Krebs-Henseleit's solution (K-H) for 10 min and followed by cardioplegia The cardioplegia consisted of StThomas solution with either traditional high potassium (16mmol/L KCl, 4 ℃, group C), or pinacidil 50?mol/L (4 ℃ in LH group or 37 ℃ in WH group ) with 5mmol/L KCl The hearts were subjected to 40 min perfusional occlusion and followed by 20 min reperfusionResults Hearts were arrested quickly in LH group, and a little slowly in WH group, but rebeated quickly , which were different significantly from those in group C ; Recovery of LVP and left ventricle contracility in LH group and WH group were remarkedly faster than those in group C (P

Objective To investigate the efficacy and safety of interventional sclerotherapy for cystic lymphatic malformation(cLM).Methods A total of 92 cases of cLM were enrolled in this study.Forty-seven cases were macrocystic lymphatic malformation(LM),32 cases were mixed LM,and 13 cases were microcystic LM.At the first treatment,56 cases with clear or light yellow cystic fluid were defined as non-bleeding group;Thirty-six cases with cloudy or dark red cystic fluid were defined as bleeding group.Sclero-therapy was performed under the guidance of fluoroscopy or ultrasonic(US),followed by an outpatient or a telephone follow-up at least 3 months after operation.Results Ninety-two patients received 140 times of interventional sclerotherapy,with an average of 1.53 times.The overall cure rate was 56.5%and the overall effective rate was 95.7%.The results of subgroup analysis showed that the overall effective rate of macrocystic and mixed LM was higher than that of microcystic LM,while the overall effective rate of macrocystic and mixed LM had no statistical difference.The cure rate of macrocystic LM was higher than that of mixed and microcystic LM,but there was no significant difference between mixed and microcystic LM.Besides,there were no statistical differences in the overall effective rate and the cure rate between the bleeding group and the non-bleeding group.Conclusion Interventional sclerotherapy is a safe and effective treatment for cLM patients.The efficacy of interventional sclerotherapy is not affected by the presence or absence of intracapsular hemorrhage during the first treatment.

Objective:To investigate the clinical effect of minimally invasive treatment of supracondylar fracture of humerus with nerve injury and the need for surgical exploration of nerve.Methods:From August 2017 to September 2020, 34 cases of children with supracondylar fracture of humerus with nerve injury in the Department of orthopedics of Shanxi Children′s Hospital were selected for retrospective analysis.Closed reduction, Kirschner wire fixation and small incision surgery were used to explore the injured nerve.The follow-up period ranged from 6 months to 3 years, with a follow-up time of (2.15±0.49) years.The elbow function, radial nerve, median nerve and ulnar nerve function were evaluated according to the trial standard of upper limb peripheral nerve function evaluation of Hand Surgery Society of Chinese Medical Association.Results:The elbow function of children in this group: excellent 31 cases, good 2 cases, fair 1 cases, poor 0 cases, excellent 33 cases.Three patients failed to take early functional rehabilitation exercise.Two patients recovered after 2.5 months of treatment by professional orthopedic rehabilitation therapists and physical therapy.One of them did not cooperate with functional rehabilitation training.After 3.5 months of treatment by orthopedic rehabilitation therapists, elbow and finger functions were not affected.Two weeks after nerve injury: radial nerve function evaluation: excellent in 15 cases, good in 3 cases, fair in 4 cases, poor in 0 cases, excellent in 18 cases.Median nerve function evaluation: excellent in 5 cases, good in 2 cases, fair in 6 cases, poor in 0 cases, excellent in 7 cases.Ulnar nerve function evaluation: excellent 5 cases, good 0 cases, fair 1 cases, poor 0 cases, excellent 5 cases.At 3 months after injury, the excellent and good rate of radial nerve, median nerve and ulnar nerve was 100%.Conclusion:The supracondylar fracture of humerus with nerve injury is treated by minimally invasive surgery, and the nerve exploration is still a few.The recovery of nerve injury after surgery is smooth, and the clinical effect is good.

OBJECTIVETo assess the levels of polycyclic aromatic hydrocarbons monohydroxy metabolites in urine of general population in China among 8 provinces, provide the baseline of the metabolites in the general population.
METHODSFrom 2009 to 2010, 18 120 subjects of general population aged 6-60 years old were recruited from 24 areas among 8 provinces in east, west and central areas of China mainland by cluster random sampling. The information of the living environment and health condition were collected by questionnaire and spot urine samples were collected, 4 680 urine samples were analysed by high performance liquid chromatography with tandem mass spectrometry, and monohydroxy metabolites distribution in urine among groups of gender and ages were analysed.
RESULTSGeometric means (GM) of 2-naphthol, 1-naphthol, 3-phenanthrol and 1-hydroxypyrene concentration in urine (95%CI) were 1.85 (1.75-1.95), 1.55 (1.50-1.61), 0.57 (0.54-0.59) and 0.82 (0.78-0.85) µg/L, respectively;and median are 2.44, <0.50, 0.72 and 0.90 µg/L, respectively. The concentration between male and female were significantly different (P < 0.01), and the concentration among the groups of population were significantly different (P < 0.01), the GM of 2-naphthol among the groups of population aged 6-12, 13-16, 17-20, 21-30, 31-45 and 46-60 years old were 1.60, 1.56, 1.69, 2.23, 1.91 and 1.86 µg/L (χ(2) = 17.90, P < 0.01), the GM of 1-naphthol in the groups were 1.30, 1.16, 1.53, 1.68, 1.80 and 1.52 µg/L (χ(2) = 76.22, P < 0.01), the GM of 3-phenanthrol in the groups were 0.78, 0.76, 0.55, 0.42, 0.50 and 0.99 µg/L (χ(2) = 66.48, P < 0.01), the GM of 1-hydroxypyrene in the groups were 0.77,0.64, 1.00, 0.84, 0.84 and 0.57 µg/L (χ(2) = 51.48, P < 0.01), respectively.
CONCLUSIONThe distribution of monohydroxy metabolites levels in urine of general population were different, it provided a basic data for the further study of polycyclic aromatic hydrocarbons biomonitoring in the population.

The construction of smart hospital is an important part of modern hospital management system,and it is also the key way to build the new system of high-quality hospital development.In terms of building smart hospitals,multi-campus hos-pitals face more difficulties and challenges than single campus hospitals,such as the lack of top-level design,the difficulty of in-tegrated management,the uneven development of hospitals and the widespread phenomenon of information islands.This study summarizes and analyzes the difficulties encountered in the construction and application of smart hospitals in multi-hospital areas.Guided by problems,it puts forward countermeasures and suggestions for the construction of refined and high-quality smart hospi-tals in multi-campus hospitals,including strengthening overall and forward-looking awareness,integrating management according to hospital conditions,characteristic development under demand guidance,establishing a data integration center for smart hospi-tals,scientific planning of talent reserve and discipline layout,etc.
