ABSTRACT

Objective To evaluate the feasibility and safety of tracheal extubation in operating room for patients with end-stage chronic obstructive pulmonary disease (COPD) after single-lung transplantation. Methods Clinical data of 57 recipients who underwent single-lung transplantation due to end-stage COPD were retrospectively analyzed. According to the evaluation indexes of tracheal extubation in operating room established by our hospital, 17 recipients eligible for tracheal extubation in operating room were assigned into the operating room extubation group (OR extubation group) and 40 recipients receiving tracheal extubation in intensive care unit (ICU) were allocated in the ICU extubation group. The evaluation results of intraoperative tracheal extubation and postoperative recovery were compared between two groups. Results Compared with the ICU extubation group, recipients in the OR extubation group had higher oxygenation index, lower arterial partial pressure of carbon dioxide (PaCO2), lower blood lactic acid level, less fluctuation range of blood pressure and fewer cases receiving extracorporeal membrane oxygenation (ECMO) during operation (all P < 0.05). Two recipients in the OR extubation group received repeated tracheal intubation at 6 and 8 h after returning to ICU, and tracheal extubation at postoperative 6 and 9 d. In the OR extubation group, time of postoperative mechanical ventilation, length of postoperative ICU and hospital stay of the recipients were shorter than those in the ICU extubation group (all P < 0.05). The incidence of grade 3 primary graft dysfunction (PGD), atrial tachyarrhythmia, continuous renal replacement therapy and 1-year survival rate did not significantly differ between two groups (all P > 0.05). Conclusions The tracheal extubation regimen in the operating room for COPD patients after single-lung transplantation established by our hospital is safe and feasible, which shortens the time of postoperative mechanical ventilation, the length of postoperative ICU and hospital stay, whereas does not increase the incidence of postoperative complications.

ABSTRACT

Objective@#To explore the consumption of sugar sweetened beverages (SSBs) and its association with behavioral problems in Chinese preschool children, and to provide a scientific basis for the prevention of behavioral problems of children.@*Methods@#A total of 7 634 children aged 3-6 years were chosen from kindergartens in 3 cities (Yangzhou, Xuzhou, Zhenjiang) in the lower reaches of Yangtze River using method of cluster sampling during October to November in 2017. Parental or guardian questionnaires were used to obtain information regarding child consumption of SSBs. The Strengths and Difficulties Questionnaire (SDQ) was used to assess children s emotional and behavioral problems. Multivariate Logistic regression model was used to explore the association between different SSBs intake frequency and children s behavioral problems.@*Results@#A total of 5 509(72.2%) consumed SSBs less than once a day, 830(10.9%) reported SSBs consumption once a day, and 1 295(16.9%) had 2 times or more intake of sugar sweetened beverages per day. After adjusting for confounding factors including age, sex, BMI, family financial status, parental education, screen time, sleep duration, and physical activities duration, multiple Logistic regression model revealed that intake of SSBs once a day was associated with an increased risk of hyperactivity disorder ( OR =1.26, 95% CI =1.01-1.57) and SDQ total difficulties ( OR =1.44, 95% CI =1.14-1.82) in boys and with an increased risk of emotional symptoms ( OR=1.34, 95%CI =1.02-1.76), conduct problems ( OR=1.53, 95%CI =1.18-2.00), hyperactivity disorder ( OR=1.79, 95%CI =1.42-2.27) and prosocial behavior ( OR=1.48, 95%CI =1.14-1.91) in girls. Intake of SSBs≥2 times per day was associated with an increased risk of emotional symptoms ( OR=1.28, 95%CI =1.02-1.59) and SDQ difficulties ( OR=1.30, 95%CI =1.07-1.58) in boys and not with behavioral problems in girls.@*Conclusion@#Sex differences are observed with respect to the association between SSBs intake and behavioral problems in preschoolers, but no significant dose response relationship was observed. More longitudinal studies are needed to further explore the association between SSBs intake and behavioral problems in preschool children as well as the underlying physiological mechanisms in future.

ABSTRACT

OBJECTIV E To investigate the calculation method of drug market share in budget impact analysis (BIA)in order to provide new ideas for BIA research. METHODS In view of the situation that some drugs had multiple indications or the indications in the drug instructions were not clear enough and inconsistent with the indications in the reimbursement catalogue , starting from the concept of “times per person ”,the parameters such as sample hospital and average treatment time per person for each time were introduced to develop a new market share calculation method. At the same time ,the calculation process was demonstrated by taking the treatment drugs for liver cirrhosis as an example. RESULTS & CONCLUSIONS Taking treatment drugs of liver cirrhosis as an example ,the calculation results of market share showed that the results of the two calculation methods were quite different. The market share calculated on the basis of “the number of people ”was mostly higher than that calculated on the basis of “times per person ”. Compared with the traditional calculation method based on “the number of people ”,the calculation method of market share based on “times per person ”could calculate the market share more accurately ,which could solve the problem that the traditional method didn ’t fully consider that most drugs had multiple indications ,the indications of drug instructions were not clear enough and inconsistent with the reimbursement catalogue ,resulting in inaccurate calculation of market share;at the same time ,this method could also be used to try to solve the problem that the total number of patients could not be obtained from epidemiological data based on the average treatment time per person of each time in the sample hospital. This method can be considered when the indications of the target drug are not clear enough or there are multiple indications ,or when the researchers collect clinical ,epidemiological and medical insurance data to estimate the number of target population ,the prediction results of market capacity do not conform to the theoretical logic or actual situation due to the lack of necessary data ,or when the target disease has the characteristics of repeated attacks and short course of disease.

ABSTRACT

Background/Aims@#Anti-phospholipase A2 receptor (PLA2R) autoantibody is the main biomarker of idiopathic membranous nephropathy (IMN). We aimed to find a new cutoff value of anti-PLA2R for patients with IMN and to explore the relevance between this antibody and baseline clinical parameters. @*Methods@#A total of 670 subjects including 374 IMN cases and 296 non-IMN controls were included between January 2017 and January 2020. All clinical parameters were collected at the time of renal biopsy. The levels of anti-PLA2R were detected by a commercial enzyme-linked immunosorbent assay (ELISA) kit. The optimal cutoff value was calculated by a receiver operating characteristic curve and compared in diagnostic efficiency. @*Results@#The optimal cutoff value of anti-PLA2R for IMN was 7.45 RU/mL with the highest Youden index, and the corresponding sensitivity, specificity, positive predictive value and negative predictive value were 80.75%, 97.97%, 98.05% and 80.11%, respectively. Anti-PLA2R levels in IMN patients demonstrated a significant positive correlation with serum creatinine and 24-hour urinary protein, while they showed a negative correlation with serum albumin and estimated glomerular filtration rate. @*Conclusions@#The recommended cutoff value of anti-PLA2R is 7.45 RU/mL using ELISA detection for distinguishing IMN from non-IMN nephropathy. The level of anti-PLA2R is related to baseline renal function in IMN. This new threshold can improve the diagnostic efficiency and facilitate early diagnosis of IMN.

ABSTRACT

Objective: To explore whether acupuncture can improve sleep disturbance, cognitive impairment and emotional disorders caused by sleep deprivation, and its association with the attenuation of oxidative stress injury in prefrontal cortex. Methods: Fifty-two male Sprague-Dawley rats were randomly divided into a control group (n=10), a model group (n=14), a manual acupuncture (MA) group (n=14), and a sham-MA group (n=14). All the groups were established as sleep deprivation models via the modified multiple platform method, except for the control group. Rats in both the MA group and the sham-MA group received corresponding intervention, respectively. After modeling and intervention, the four groups received three behavioral tests, namely sleep monitoring, by comprehensive lab animal monitoring system (CLAMS), Morris water maze (MWM) test and open-field test (OFT), followed by oxygen free radical level test and Western blot (WB) detection for the expression levels of Bax and Bcl-2. Results: The MA group derived more sleep time within 24 h than either the model group or the sham-MA group (both P<0.05). On MWM orientation navigation test day 1, there were no significant differences in escape latency among the control, MA and sham-MA groups (P>0.05), and the escape latency was significantly shorter in these three groups than that in the model group (all P<0.05). On test day 4, the escape latency was markedly shorter in the MA group than that in either the model group or the sham-MA group (both P<0.05); meanwhile, the MA group showed significantly better performance compared with these two groups in space probe test (both P<0.05). In OFT, compared with the control group, there was a significant decline in the horizontal movement score in the other three groups (all P<0.05), and the decrease was more significant in the model group and the sham-MA group than that in the MA group (both P<0.05). The superoxide dismutase (SOD) content was markedly higher and the malondialdehyde (MDA) content was markedly lower in the MA group than those in the model group and the sham-MA group (all P<0.05). Compared with the model group and the sham-MA group, the expression of Bax was significantly lower and the expression of Bcl-2 was significantly higher in the MA group (all P<0.05). Conclusion: MA therapy can lengthen the sleep time in sleep-deprived rats and improve learning and memory impairments induced by sleep deprivation, and the underlying mechanism may be associated with the enhancement of antioxidant capacity in the prefrontal cortex and the inhibition of hippocampal neuronal apoptosis.

ABSTRACT

Objective:To investigate the clinical effect on ultrasound-guided vascular access-interventional therapy of hemodialysis in day surgery mode.Methods:Hemodialysis patients with vascular access dysfunction who underwent ultrasound-guided interventional therapy in the First Affiliated Hospital of Xi'an Jiaotong University from September 1, 2018 to October 31, 2020 were retrospectively analyzed. Demographic and clinical data were collected by electronic medical record system and telephone follow-up. Kaplan-Meier method was used to analyze the patency rate of vascular access.Results:A total of 421 cases of ultrasound-guided vascular access intervention were performed in 269 patients. The technical success rates of stenosis, chronic occlusion and acute occlusion lesion were 98.8%, 90.6% and 86.4%, respectively, and 406 cases (96.4%) of 246 patients were clinically successful. The postoperative brachial artery blood flow was 821(627, 1 029) ml/min, which was significantly higher than 309(202, 453) ml/min before the operation ( Z=-13.547, P<0.001). No serious complications occurred during and after the operation. At 6, 12, 18 and 24 months after operation, the primary patency rate was 74%, 59%, 48% and 45%, respectively, the assisted primary patency rate was 94%, 91%, 88% and 82%, and the secondary patency rate was 96%, 93%, 91% and 86%. Compared with the conventional inpatient surgery mode, the total cost of the day surgery mode was significantly reduced [12 067(10 051, 13 198) yuan vs 14 986(12 411, 20 643) yuan, Z=-13.185, P<0.001], and the hospital stay was significantly shortened [5.1(3.5, 6.9) h vs 73.4(31.6, 146.6) h, Z=-13.348, P<0.001]. Conclusion:It is safe and effective to perform interventional therapy for vascular access malfunction under ultrasound in day surgery mode, which can save cost and time of hospitalization, and can be carried out in hospitals with relevant conditions.

ABSTRACT

Objective To study the prevalence of cigarettes and e-cigarettes, and to analyze its influencing factors among high school students in Wenzhou. Methods:A self-administered questionnaire survey was conducted among a total of 3 785students from senior high schools and vocational high schools in Wenzhou from September to November in 2020, who were selected by stratified cluster sampling. Their demographic information and the use of tobacco [including the use of cigarettes, e-cigarettes (currently smoking and smoking attempt), and the dual use of them] were asked in the questionnaire of “Global Youth Tobacco Survey”(GYTS). Proportion and rate were used to describe their demographic characteristics and smoking prevalence. Chi-square test was used to compare the difference in smoking prevalence of the high school students with selected characteristics. Multinomial logistic regression was used to analyze the influencing factors of tobacco use among the participants.Results:Among the 3 785 questionnaires, 3 740 were completed, and effective rate was 98.80%. The smoking attempt rate, current smoking rate, e-cigarette attempt rate, e-cigarette using rate, and dual using rate of the high school students in Wenzhou were 11.79% (441/3 740), 2.57% (96/3 740), 10.00% (374/3 740), 2.86% (107/3 740), 0.99% (37/3 740), respectively. Male students, vocational high school students, the students whose parents smoking showed higher smoking attempt rate, current smoking rate, e-cigarette attempt rate than female student, senior high school students and those parents who don′t smoke, respectively (all P<0.05). Best friend smoking [6.076 (2.872-12.855); 4.630 (2.656-8.071)], vocational high school [3.226 (1.877-5.546); 2.238 (1.432-3.496)] were risk factors for e-cigarette and the cigarettes use, belief that whether smoking or not does not make any difference in social activities [0.160 (0.077-0.331); 0.193 (0.096-0.387)], or smoking in social activities makes people more uncomfortable [0.037 (0.018-0.077); 0.155 (0.083-0.288)] were protective factors of e-cigarette and the cigarettes use. Additionally, passive smoking in past week [2.194 (1.129-4.262)], free tobacco products received [2.836 (1.018-7.905)], seeing smoking in campus [2.072 (1.111-3.863)] were all risk factors, while belief that smoking makes young people less attractive [0.280 (0.116-0.676)], not having been to tobacco retail outlets and unexposed to tobacco advertising or promotion [0.241 (0.123-0.473)] can protect senior middle school student away from cigarette. As to e-cigarette, boys were the risk factors [1.831 (1.100-3.050)]; as opposed to being a risk factor for cigarette use [1.942 (1.084-3.478)], rural area was a protective factor for e-cigarette use [0.639 (0.410-0.994)] among high school students in Wenzhou. Conclusions:High school students have relatively low rates of smoking cigarettes and e-cigarette in Wenzhou. Vocational students, best friend smoking are risk factors of e-cigarette and the cigarettes, beliefs that whether smoking or not does not make any difference or smoking makes people more uncomfortable in social activities are protective factors.

ABSTRACT

In order to improve the success rate of supraclavicular deep venous catheterization and reduce mechanical complications, we present an auxillary maneuver in regard to supraclavicular subclavian catheterization basing on the relatively fixed anatomy of subclavian vein and its adjacent surroundings, furthermore, we revised the standardized procedure of supraclavicular subclavian catheterization. The maneuver is summarized in the shape of verses (verses: thumb navigation is well designed according to anatomy. Needle penetrated into vein should be parallel to coronal plane. Fine needle in position should be immobilized. Is it difficult for parallel puncture? Pressure determination is required when needle is in place. It is critical to distinguish which vessel has been inserted. Guidewire is advanced smoothly. Check blood return after expansion of skin and catheterization.). For teaching convenience, verses are considered to be more concise and memorable, as well as applicable to clinical practice, in order to provide some help for clinical teaching.

ABSTRACT

Objective:To explore the reasonable combination of Artemisiae Annuae Herba and Chuanxiong Rhizoma in treatment of cerebral malaria and investigate its mechanism based on network pharmacology. Method:The traditional Chinese medicine systems pharmacology database and analysis platform (TCMSP) and SymMap were used to obtain all the chemical components of Artemisiae Annuae Herba and Chuanxiong Rhizoma and the action targets were screened to construct a component target protein-protein interaction (PPI) network. Target genes related to cerebral malaria were collected with use of GeneCards and DisGeNET databases. Common targets were screened by overlapping drug targets and disease targets, and protein-protein interaction network analysis was performed to get key targets. Gene ontology (GO) functional enrichment analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis were carried out to get main signaling pathways. Furthermore, the classical experimental cerebral malaria mouse model was used to detect survival curve, protozoanemia level, survival rate, experimental cerebral malaria (ECM) coma and behavior scores. RayBio<sup>®</sup> cytokine antibody array was used to detect the expression level of cytokines in tissues and experiment was conducted for verification. Result:After combination of Artemisiae Annuae Herba and Chuanxiong Rhizoma, 23 active ingredients, 179 drug targets, and a total of 100 common targets of the drug and disease were obtained. GO functional analysis identified 59 items (<italic>P</italic><0.05), involving cytokine activity, growth factor activity, immune response, etc. KEGG pathway analysis revealed 51 related signaling pathways. The experimental results showed that the combined use of Artemisiae Annuae Herba and Chuanxiong Rhizoma could significantly improve the clinical signs of ECM mice, such as survival state, coma and behavioral scores. In the detection of expression levels of related cytokines in mice, the expression levels of <italic>γ-</italic>interferon (IFN-<italic>γ)</italic>, interleukin-10 (IL-10), IL-4, and IL-1<italic>β</italic> in the compatible drug combination drug were significantly higher than those in the model group (<italic>P</italic><0.05), which was consistent with the overlapping core targets predicted by network pharmacology. Conclusion:Based on the network pharmacology analysis and<italic> in vivo</italic> experiment verification, this study confirmed the synergistic effect of the combination of Artemisiae Annuae Herba and Chuanxiong Rhizoma in the treatment of cerebral malaria, providing clear direction for further mechanism research, and a new possibility for the clinical intervention of cerebral malaria.

ABSTRACT

@#Objective     To identify the risk factors for postoperative recurrence of peripheral solid small-nodule lung cancer (PSSNLC) (T≤2 cm), and to explore the effects of surgery types on prognosis. Methods     We extracted data from Western China Lung Cancer Database (WCLCD), a prospectively maintained database at the Department of Thoracic Surgery, West China Hospital, Sichuan University, and Surveillance, Epidemiology, and End Results (SEER)  database for peripheral solid small-nodule lung cancer patients (T≤2 cm N0M0, stageⅠ) who underwent surgery between 2005 and 2016. We used univariable and multivariable logistic regression to analyze risk factors for recurrence of PSSNLC. We applied propensity-score matching to compare the long-term results of segmentectomy and lobectomy, as well as the survival of patients from WCLCD and SEER. We finally included 4 800 patients with PSSNLC (T≤2 cm N0M0)(WCLCD: SEER=354∶4 446). We matched 103 segmentectomies and 350 lobectomies in T≤1 cm, and 280 segmentectomies and 1 067 lobectomies in 1 cm<T≤2 cm at a ratio of 1∶4 according to the propensity scores. Results     The results of multivariable logistic regression showed that older age (HR=1.04, 95%CI 1.03-1.05, P<0.001), male (HR=1.60, 95%CI 1.37-1.88, P<0.001), squamous carcinoma (HR=1.65, 95%CI 1.40-1.95, P<0.001), lymph node removed (HR=0.97, 95%CI 0.96-0.99, P<0.001) were risk factors for recurrence after surgery. We found that segmentectomy and lobectomy could reach similar survival in PSSNLC patient with either T≤1 cm or 1 cm<T≤2 cm. Analyses of 1 441 patients with PSSNLC after matching (WCLCD∶SEER=325∶1 116) indicated that the 5-year overall survival rate of the patients in WCLCD was better than that in SEER database ( 89.8% vs. 77.1%, P<0.001). Conclusion     Older age, male, squamous carcinoma, and lymph node removed are the risk factors for recurrence of PSSNLC. Segmentectomy shows similar survival in PSSNLC patient with either T≤1 cm or 1 cm<T≤2 cm N0M0. The patients in the WCLCD shows better survival compared with of the patients in the SEER database.

ABSTRACT

Objective To improve the understanding of Danon disease and the efficacy of heart transplantation by multi-disciplinary team (MDT) pattern. Methods Prior to heart transplantation, MDT consultation was performed on one case of Danon disease, an extremely rare X-chromosome dominant genetic disease. The content of consultation included surgical indication, preoperative preparation and postoperative precaution, as well as the role of MDT in the treatment of Danon disease was summarized. Results Preoperative echocardiography showed that the patient presented withdilated-phase of hypertrophic cardiomyopathy complicated with heart failure, which was considered as Danon disease with end-stage heart failure. After MDT consultation, the patient received the preoperative treatment including anti-heart failure, reduction of pulmonary artery pressure, intra-aortic balloon pump (IABP) assistance, liver protection, strengthening nutritional support, etc. The patient underwent orthotopic heart transplantation after a suitable donor was matched. The patient developed muscle weakness in the limbs 5 days after operation, which was gradually mitigated after reducing the dose of glucocorticoid. At postoperative 48 days, the patient was discharged in good condition and continually treated with triple immunosuppressive regimen after discharge. Reexamination at postoperative 6 months revealed that the patient was in good health without any abnormality in electrocardiogram and echocardiography images. Conclusions Danon disease is extremely rare and MDT pattern may enhance the efficacy and safety of treatment by heart transplantation.

ABSTRACT

OBJECTIVE@#To compare accuracy of anterior cervical pedicle screws between assist of rapid prototyping 3D guide plate and free-hand insertion, and evaluate the safety of two methods.@*METHODS@#Eight adult cervical cadaver specimens after formaldehyde immersion, including 4 males and 4 females, aged 32 to 65(40.3±5.6) years old. After X-ray examination to exclude bone damage and deformity, 4 of them (3D guide plate group) randomly selected were for CT scan to obtain DICOM format data, and the data was imported into Mimics software for model, designed the ideal entry point and nail path for anterior cervicaltranspedicular screw (ATPS). After obtaining the personalized guide plate of the nail channel, it was exported as STL data, and the individual guide plate was printed by rapid prototyping and 3D printing technology. In turn, with the assistance of 3D guide plates, one-to-one personalized ATPS screws were placed on the four lower cervical cadaver specimens. Another 4 (free-hand group) lower cervical cadaver specimens were implanted with ATPS screws using free-hand technique. All specimens were performed CT thin-layer scanning and three-dimensional reconstruction after operation. The Tomasino method was used to evaluate the safety of the screws on the CT cross-sectional and sagittal images, to determine whether there was a cortical puncture of the lower and inner edges of the pedicle.

ABSTRACT

With the development of social economy and improvement of people's health condition, life expectancy continues to extend and people are more concerned about the quality of life. Nowadays people's attention has shifted from living longer lives to living healthier lives. Life expectancy can only reflect the length of life, but not the health condition and quality of life. Meanwhile, healthy life expectancy contains death and disability information, which comprehensively reflects the length and quality of life and evaluates the health status of the population comprehensively. Through literature search and review, the article summarized the research on healthy life expectancy in recent years, including the concept proposal, index development, calculation, and application progress of health life expectancy. The research methods of healthy life expectancy are summarized in order to provide academic reference for further research.

ABSTRACT

italic>Tert-butanol is an organic solvent, widely used in the medical field and chemical industry. It could be characterized by high crystallization temperature and vapor pressure. It could be easily sublimed and removed during the freeze-drying process. This review mainly describes the use of tert-butanol in the lyophilized formulations of poorly soluble drugs, the lyophilization solvent of porous structure productions, and as an ice crystal growth guider. In addition, the application of tert-butanol in nano drugs and aerogels has also been reviewed, as well as the current research progress in its quality and safety.
