ABSTRACT
The mechanisms underlying exercise-induced neuroprotective effects after traumatic brain injury (TBI) remained elusive, and there is a lack of effective treatments for TBI. In this study, we investigated the effects of an integrative approach of exercise and Yisaipu (TNFR-IgG fusion protein, TNF inhibitor) in a mouse TBI model. Male C57BL/6J mice were randomly assigned to a sedentary group or a group that followed a voluntary exercise regimen. The effects of 6-week prophylactic preconditioning exercise (PE) alone or in combination with post-TBI Yisaipu treatment on moderate TBI associated deficits were examined. The results showed that combined treatments of PE and post-TBI Yisaipu were superior to single treatments on reducing sensorimotor and gait dysfunctions in mice. These functional improvements were accompanied by reduced systemic inflammation largely via decreased serum TNF-α, boosted autophagic flux, and mitigated lesion volume after TBI. Given these neuroprotective effects, composite approaches such as a combination of exercise and TNF inhibitor may be a promising strategy for facilitating functional recovery from TBI and are worth further investigation.

Objective:To evaluate the clinical effectiveness and safety of a respiratory training device (patent No.201320672057.6), which was developed and produced in China.Methods:Sixty patients with chronic respiratory diseases admitted in China-Japan Friendship Hospital from May 2019 to July 2019 were enrolled in the study. Patients were randomly divided into trial group ( n=30) and control group ( n=30), in the trial group, respiratory training device was used on the basis of conventional treatment, while in the control group, patients received conventional treatment only. Baseline data were collected at the time of enrollment, patients were followed up every 4 weeks, and the final data were collected at the 16th week. The primary outcomes were mMRC score, LCQ score and expectoration. The secondary outcomes were pulmonary function, respiratory muscle strength, SpO 2, FeNO, SGRQ score, times of acute exacerbation and adverse events. Results:There was no significant difference in proportion of decreased mMRC score between trial group and control group [36.0% (9/25) vs. 23.1% (6/26), Z=-1.044, P=0.301). On expectoration, the decrease rate of no-sputum patients in the trial group was significantly higher than that in the control group [28.0%(7/25) vs. 7.7%(2/26), Z=2.050, P=0.041]. In addition, 56%(14/25) patients in the trial group had a decrease in sputum volume compared to 19.2%(5/26)in the control group ( Z=-2.574, P=0.010). There was no statistical difference between the two groups before and after the follow-up in LCQ score( F=0.668, P=0.418). The PEF of pulmonary function in the trial group was significantly improved compared to the baseline( F=4.532, P=0.039); and R 35 was also significantly improved in the trial group( F=4.125, P=0.048). In terms of quality of life, the study found no statistical differences in SGRQ scores between baseline and follow-up. However, the SGRQ symptom score decreased significantly in trial group( F=7.481, P=0.009). There was no statistical difference in acute exacerbation between the two groups ( Z=0.297, P=0.766). No adverse events occurred during the follow-up period. Conclusions:This study evaluated the clinical effectiveness and safety of a respiratory training device developed in China. In terms of the clinical effectiveness, the device can reduce sputum, increase PEF, reduce R 35, indicating that there is a certain therapeutic effect. It is not clear that the device can reduce the severity of dyspnea and pulmonary function, improve quality of life, reduce the times of acute exacerbation. In terms of safety, the device did not show adverse effects during follow-up in this study.
ABSTRACT
Objective To compare the complete mitochondrial genome sequences of two phenotypes of Paragonimus westermani isolated from Fujian Province with different sizes of metacercariae, and perform a phylogenetic analysis of various geographical isolates of P. westermani from Asia, so as to identify the possible genetic characteristics associated with the P. westermani phenotypes. Methods P. westermani metacercariae with different sizes (large metacercariae, 380–420 μm in diameter; small metacercariae, 320–340 μm) isolated from freshwater crabs were used to infect dogs, and the eggs and adult worms of P. westermani were collected from the dog stool samples and lung tissues. Then, the egg size and morphology were compared. In addition, genomic DNA was extracted from the adult worms of the two phenotypes of P. westermani and used for the PCR amplification to yield the complete mitochondrial genome sequence. Sequence structure and phylogenetic analyses were performed based on the complete mitochondrial genome of P. westermani. Results Following infection with large and small P. westermani metacercariae, the adult worms recovered from the dog lung had a thick body, and had oral and ventral suckers. The ventral sucker was located slightly in front of the midline of the body, and testes, ovary and vitelline gland were seen in the adult worms. Following fixation, the adults appeared oval, with an approximately 1.7∶1 of the length-width ratio. The length and width of the eggs isolated from the fecal samples of dogs infected with large and small P. westermani metacercariae varied significantly, and the large metacercariae produced bigger eggs than the smaller metacercariae. Based on the morphological features of adults and eggs and the ITS2 sequences, both phenotypes were identified as P. westermani. The complete mitochondrial genome sequence analysis of adults showed almost consistent sequences in the protein-coding region of the mitochondrial genome of adult worms derived from large and small metacercariae, with a major variation seen in the former non-coding region. Sliding window analysis revealed the most polymorphic region within the ND4 gene across the mitochondrial genome from various geographical isolates of P. westermani, and phylogenetic analysis showed that both phenotypes were clustered into the Chinese branch of P. westermani, which was close to the Japanese branch and distinct from the South/Southeast Asian branch. Conclusions The genetic distance between the phenotypes of P. westermani isolated from Fujian Province is near at a mitochondrial genome level, with no remarkable genetic differentiation seen; however, the mutation and structural changes in the non-coding region may result in the phenotypic variations. In addition, there is a distinct variation of the evolutionary rate in the mitochondrial coding genes, suggesting the selection of appropriate molecular markers during the phylogenic researches.
ABSTRACT
Objective: To observe the clinical effect of heat-sensitive moxibustion plus lactulose oral liquid for postoperative constipation of mixed hemorrhoid.Methods: A total of 70 patients were randomized into a treatment group and a control group, with 35 cases in each group by a random number table. Patients in the control group received lactulose oral liquid alone, while those in the treatment group received additional heat-sensitive moxibustion at Shenque (CV 8). The treatment was given once a day for 15 consecutive days. The defecation interval time, defecation duration, the scores of stool form, visual analog scale (VAS) and patient assessment of constipation quality of life questionnaire (PAC-QOL), as well as the serum substance P (SP) and nitric oxide (NO) levels were measured before and after treatment. Results: After treatment, the stool form score, defecation interval time and defecation duration in the two groups dropped significantly (all P<0.05), and they were lower in the treatment group than in the control group (all P<0.05). After treatment, the VAS scores in the two groups dropped significantly (both P<0.05), and it was lower in the treatment group than in the control group (P<0.05). After treatment, the PAC-QOL scores in the two groups dropped significantly (both P<0.05), and it was lower in the treatment group than in the control group (P<0.05). After treatment, the serum SP and NO levels in the two groups improved significantly (all P<0.05), and showed statistically significant differences between the treatment group and the control group (both P<0.05). Conclusion: Heat-sensitive moxibustion plus lactulose oral liquid can improve stool form, shorten defecation interval time and defecation duration, alleviate defecation pain, and improve quality of life (QOL) for patients with postoperative constipation of mixed hemorrhoid, which may be related to the regulation of the SP and NO levels.
ABSTRACT
Exosomes are tiny vesicles secreted by most endogenous cells, and the extracellular vesicles (EVs) are specifically secreted by cells. Recently, it was found that exosomes contain a large quantity of important substances such as proteins, nucleic acids, and lipids, which play important roles in material exchange and information transmission in cell-cell communication, and in modulating the immune response, metabolism, and expansion, metastasis, and drug resistance of tumors. This paper summarizes the recent researches on exosomes in parasites and parasitic diseases and hopes to be helpful for improving the researches of parasites and parasitic diseases.

ABSTRACT
Objective To investigate the infection status of intestinal nematodes and their risk factors in rural residents of Jiangxia District, Wuhan City, so as to provide the reference for the establishment of targeted prevention and control measures. Methods According to the requirements of cross-sectional study of the national human key parasitic diseases, the residents in Shanpo Sub-district, Jiangxia District were randomly selected as the objects for the investigation of the infection status of Ascaris lumbricoides, hookworm and Trichuris trichiura. A questionnaire survey was performed simultaneously. Results Totally 236 residents received the stool tests, and only the hookworm eggs were found, with an infection rate of 7.63% (18 cases). The survey of intestinal parasitic infection status and their risk factors in 600 residents found 397 cases of suspected roundworm infection, 355 cases of suspected hookworm larvae dermatitis, 295 cases of suspected hookworm infection, and 145 cases of suspected whipworm infection, respectively. The Logistic regression analysis found that the risk factors of suspected roundworm infection included not always washing hands after toilet, using manure and fertilizer, and not often wearing shoes when doing farm work; the protective factors included knowing how roundworm infection was gained, and not using fresh dung for fertilization. The risk factors of suspected hookworm infection included using well water and pond water as the source of drinking water, eating food off the ground, using manure and fertilizers, and not washing when there was only one cutting board, and its protective factors included using tap water and well water as drinking water source, knowing how the roundworm infection was gained, and sometimes or not suing fresh feces for fertilization. The risk factors for suspected whipworm infection included eating food off the ground. Conclusions The intestinal parasite prevalence in the residents of the Shanpo Sub-district, Jiangxia District in Wuhan City is relatively high, and some risk factors associated with their infection indeed exist. Therefore, the regional government and health department should strengthen the health education to improve the residents’ knowledge about parasitic diseases and selfprotection awareness. At the same time, the residents should take physical examination regularly and take necessary deworming treatment to effectively control the prevalence and spread of intestinal parasitic diseases.

ABSTRACT
Objective To investigate the consecutive influenza vaccination situation among the patients with type 2 diabetes and the influencing factors. Methods Based on the influenza vaccination information obtained from the vaccination case registrations of the adult vaccination clinic in all the street community health service centers in Jiangdong District and the information of patients with type 2 diabetes derived from the chronic disease monitoring management information system of Zhejiang Province. A total of 269 urban household registration patients suffered from diabetes mellitus before August 2013 and had the influenza vaccination in 2013/2014, 2014/2015, 2015/2016 and 2016/2017 were ensured and analyzed by the ordinal regression analysis to explore the influencing factors of the consecutive influenza vaccination among the patients with type 2 diabetes. Results The influenza vaccination rates among the patients with type 2 diabetes in 2013/2014 (0.74％), 2014/2015 (0.82％), 2015/2016 (1.04％) and 2016/2017 (1.13％) were increasing year by year (χ2trend=11.663, P=0.001) with the annual rate of 0.95％. The once, twice, three and four times of the influenza vaccination accounted for 60.60％ (163 patients), 19.33％ (52 patients), 13.01％ (35 patients) and 7.06％ (19 patients), respectively. The ordinal regression analysis showed that patients below the age of 66 (OR=0.542, 95％CI: 0.310-0.948) and patients with a primary and middle school degree (ORprimary=0.436, 95％CI: 0.253-0.752; ORmiddle=0.438, 95％CI: 0.265-0.724) were all more likely to cease the vaccination. Patients who get the first time vaccination after be diagnosed in three years (OR=2.509, 95％CI: 1.412-4.459) were more likely to get immunized continuously. Conclusion The influenza vaccination rates among patients with type 2 diabetes were low. The patients aged 76 years old and above, with a higher degree and newly diagnosed were more likely to accept the consecutive influenza vaccination.

ABSTRACT
Objective To probe into the total number and development status of respiratory physicians in China, and to analyze existing problems, for reference in making strategy and policy decisions in professional development of respiratory physicians in the country. Methods The basic information of China′s healthcare institutions and healthcare manpower in 2015 were provided by the Statistics Center of the National Health Commission. The number of respiratory specialists and their profile, drawn from such basic information, were subject to descriptive statistics. Results In 2015, there were 2.729 million medical practitioners ( including assistant doctors ) nationwide, 30.3 thousand among whom being respiratory physicians, accounting for 1.11% of the total. Among these respiratory physicians, practicing respiratory physicians account for 87.1% , respiratory physicians with a master degree and above account for only 19.7% , respiratory physicians with over 10 years of working experience account for 65.8% , respiratory physicians with senior titles account for only 21.4% , and 89.4% of the respiratory physicians work in general hospitals. Conclusions By the criteria of specializing in respiratory specialty over five years and being attending or above, the number approximates 14. 6 thousand nationwide. If practicing ( assistant) physicians specializing in respiratory specialty are also included, the number may hit 30. 3 thousand. Such a number, compared with other specialties, may be sufficient, yet their competence is far from satisfactory. Therefore it is imperative to build a standardized pulmonary medicine fellowship training system for their competence improvement.
ABSTRACT
Objective To study the clinical events and risk factors of in stent restenosis (ISR) during the ＞1 year follow-up period after vertebral artery stenting.Methods Forty-six patients with 48 stents implanted from the Shaoxing No.2 Hospital between January 2010 and October 2016were divided into ISR group (n=8) and ISR-free group (n=38) or clinical events group (n=8)and clinical events-free group (n=38).The influencing factors for their long-term clinical outcome were analyzed after vertebral artery stenting.Results The mean stenosis length was (7.7 ± 4.6mm,the stenosis severity was 80.7％±14.2％,and the residual stenosis was 3.0％±8.4％ before stenting.The mean angiographic follow-up time was 31.6±20.8 months,during which ISR occurred in 8 patients (17.4％).The mean clinical follow-up time was 53.8±27.0 months,during which clinical events occurred in 8 patients (17.4％).Survival analysis showed that ISR usually occurred in the first 20 months and no clinical events occurred in 23 patiemts (50.0％) after vertebral artery stenting.The stenosis was significantly longer in ISR group than in ISR-free group (6.00±2.00 mm vs 2.76±4.14 mm,P=0.003).The diameter of stents was significantly shorter in clinical events group than in clinical events-free group (3.53±0.93 mm vs 4.18±0.67 mm,P=0.024).Conclusion The long-term clinical follow-up outcome is associated with the length and diameter of stents in patients after vertebral artery stenting.

<p><b>BACKGROUND</b>Numerous studies have demonstrated that patients with Parkinson's disease (PD) have a higher prevalence of substantia nigra (SN) hyperechogenicity compared with controls. Our aim was to explore the neuroimaging characteristics of transcranial sonography (TCS) of patients with PD and those with PD with dementia (PDD). The correlation between the echogenicity of the SN and clinical symptoms in Chinese patients with PDD was also assessed.</p><p><b>METHODS</b>The ratios of SN hyperechogenicity (SN+), maximum sizes of SN+, and widths of third ventricle (TV) were measured using TCS for all the recruited patients. Data were analyzed using one-way analysis of variance, rank-sum test, Chi-square test, and receiver-operating characteristic (ROC) curve analysis.</p><p><b>RESULTS</b>The final statistical analysis included 46 PDD patients, 52 PD patients, and 40 controls. There were no significant differences in ratios of SN+ and maximum sizes of SN+ between PDD and PD groups (P > 0.05). TV widths were significantly larger in PDD group (7.1 ± 1.9 mm) than in PD group (6.0 ± 2.0 mm) and controls (5.9 ± 1.5 mm, P < 0.05); however, the ratios of enlarged TV did not differ among the three groups (P = 0.059). When cutoff value was set at 6.8 mm, the TV width had a relatively high sensitivity and specificity in discriminating between PDD and PD groups (P = 0.030) and between PDD group and controls (P = 0.003), based on ROC curve analysis. In PDD patients, SN+ was more frequently detected in akinetic-rigid subgroup, and patients with SN+ showed significantly higher Hoehn and Yahr stage and Nonmotor Symptoms Questionnaire scores (P < 0.05).</p><p><b>CONCLUSIONS</b>Compared to Chinese patients with PD, patients with PDD had a wider TV, altered SN sonographic features, and more severe clinical symptoms. Our findings suggest that TCS can be used to assess brain atrophy in PD and may be useful in discriminating between PD with and without dementia.</p>
ABSTRACT
Mineral Chinese medicine is the distinctive part of the Chinese traditional medicine. The mineral Chinese medicines containing mercury elements such as cinnabaris, calomelas and hydrargyri oxydum rubrum are widely applied in the clinical conditions because of their efficacy of sedative, sterilization, removing necrotic tissue and promoting granulation. However, the rationality and security of clinical application are questioned because of the toxic effect caused by mercury compounds. This paper would summarize the efficacy of the mineral Chinese medicines containing mercury element, as well as their hepatotoxicity, nephrotoxicity, embryotoxicity, and neurotoxicity effect and mechanisms. Improper usage or high dose of the mineral Chinese medicines containing mercury element would cause acute hepatotoxicity. Cinnabaris, calomelas and hydrargyri oxydum rubrum may lead to chronic hepatotoxicity, nephrotoxicity, embryotoxicity and neurotoxicity when they were applied externally to the skin for long-term use. In addition to the accumulation of mercury elements in the tissues and organs, the species and forms of mercury compounds absorbed into the body in different ways, should be also studied in order to understand the toxicity of the mineral Chinese medicines containing mercury element. Meanwhile the dose and period of treatment shall be also considered in order to provide the references for rational and safe clinical application of the mineral Chinese medicines containing mercury element.
ABSTRACT
Objective To investigate the relationship between bus drivers' personality characteristics with driving experience and to provide reference for safe driving. Methods A total of 158 bus drivers who work for one year and above were extracted by random sampling from a bus company in Ningbo during March 2016 to May 2016. The survey was carried out by 16 personality factor questionnaire (16PF), and compared with the national norm. Results The subjects were male, and average age was 39.24±6.78. The average bus driving year was 15.54±6.66 and mainly with high school education (62.66%) . The scores of agreeableness (9.21±3.18), intelligence (8.12±1.81), excitability (9.60± 3.26), excitement (10.84±4.59), suspicion (8.94±2.87), introversion (9.01±2.60), experiment (10.18±2.52) and independence (10.51±3.13) of the subjects were significantly lower than the national norm (P<0.05) . The scores of sensitivity (10.67±2.72), anxiety (9.60±3.78) and the self-discipline (13.30±2.42) were significantly higher than the national norm (P<0.05) . And 54.43% of bus drivers have high score in eight sub-personality analysis of mental health factors and 67.09% of them have low score in professional achievement factor. The analysis of personality characteristics of bus drivers with different bus driving experiences showed that the highest stability score was in 16 bus driving years and above, and the highest anxiety score was in 6~ <11 bus driving years and the highest tension and anxiety score were in 11 ~ <16 bus driving years (P <0.05) . Conclusion Bus drivers show special professional personality traits, and some characteristics will be strengthened and weakened with the growth of bus driving experience. It is necessary to carry out special training for the bus drivers with different bus driving experience, especially about dealing with various types of accident risk for new bus driver timely and psychological counseling for old bus driver regularly.
ABSTRACT
Objective To learn the present setup of respiratory departments as well as development of diagnosis and treatment in China, for reference and policy making of the respiratory specialty development. Methods In May and June 2016,3 202 hospitals were surveyed, to learn their respiratory department development,development of sub-specialty,naming of departments,staffing ratio of the medical staff to bed,basic indicators for medical services,medical techniques and disease types treated. Results 77.8% of the tertiary hospitals and 38.8% of the secondary hospitals have independent respiratory departments. Among such tertiary hospitals,54.4% of them have respiratory intensive care units,21.8% have respiratory & sleep disorder clinics, and 13.1% have smoking cessation clinic. The physician-nurse ratio of respiratory department of such hospitals amounted to 1:1.66, while that of secondary hospitals to 1:1.61. 99.8% of the tertiary hospitals and about 95.0% of the secondary hospitals are competent of invasive positive pressure ventilation,noninvasive mechanical ventilation,and pulmonary function test among others. Conclusions Rooms of improvement are found in the following areas. Poor respiratory specialty and sub-specialty construction at such hospitals; insufficient nursing staff; tertiary hospitals have not formed unique advantages in diagnosis and treatment techniques and types of diseases; hierarchical medical system is to be further established.
