ABSTRACT
Objective:To investigate the effect of Chinese reading aloud training (c-RAT) on cognitive function and activities of daily living in patients with vascular cognitive impairment no dementia (VCIND).Methods:From January 2018 to January 2019, totally 80 patients with VCIND in the General Hospital of Xingtai Mining Group were enrolled.Subjects were randomized grouped into c-RAT group ( n=43) and control group ( n=37). The c-RAT group was asked to read aloud the Chinese paper for 5 days a week for 12 weeks.At the time of enrollment and 12 weeks after the intervention, the Montreal cognitive assessment (MoCA), trail making test (TMT), auditory verb learn test (AVLT), digit symbol substitution test (DSST) and modified Barthel index (MBI) were filled out. Results:Compared with control group, the difference of D-value in c-RAT group was statistically significant in MoCA total scores(4.00(2.00), 1.50(0.50), Z=3.012, P=0.003), scores of MoCA-Visual space execution (2.00(1.00), 0.00(2.00), Z=2.787, P=0.008), MoCA-attention (1.00(1.00), 0.00(0.50), Z=2.369, P=0.022), MoCA-language (1.00(1.00), 0.00(0.75), Z=3.049, P=0.000)and MoCA-delayed recall(2.00(2.00), 0.00(1.00), Z=2.043, P=0.014), TMT-A scores (-8.00(23.00), 10.50(30.25), Z=2.120, P=0.039), AVLT scores (1earning)(3.00(2.00), 0.50(0.75), Z=2.266, P=0.039) , AVLT scores (recall)(2.00(1.00), 0.00(1.00), Z=2.974, P=0.003)、AVLT scores (recognition) (2.00(0.00), 0.50(1.50), Z=3.054, P=0.000)and DSST scores ((4.96±0.71), (2.39±0.78), t=2.572, P=0.014), while there were no significant differences in the rest parts of MoCA, TMT-B and MBI( P>0.05). The increased scores in DSST were positively correlated ( r=0.205, P=0.006) with the number of reading aloud tasks finished. Conclusion:C-RAT can improve general cognition, especially in information processing speed, executive function, attention and auditory memory.
ABSTRACT
OBJECTIVE: To assess the reliability and validity of Adversity Quotient Scale in evaluating the adversity quotient among nurses. METHODS: A total of 409 nurses were selected as study subjects from three first-class hospitals in Fujian Province by cluster sampling method. The adversity quotient was investigated by Adversity Quotient Scale and its reliability and validity were tested. RESULTS: The Cronbach′s alpha coefficient, Spearman-Brown coefficient, Guttman Split-Harf coefficient and retest reliability of Adversity Quotient Scale were 0.931, 0.826, 0.823 and 0.940, respectively. The content validity ratio of Adversity Quotient Scale was 0.980.

CONCLUSION: Adversity Quotient Scale has a good reliability and validity in the assessment of nurses, which can be a reliable and effective adversity quotient assessment tool.
ABSTRACT
Objective To investigate the efficacy of levosimendan and dobutamine in the treatment of dilated cardiomyopathy combined with refractory end-stage heart failure. Methods A total of 90 patients with dilated cardiomyopathy and refractory end-stage heart failure in our hospital from February 2016 to February 2017 were enrolled and grouped according to digital table method. The control group received conventional anti-heart failure treatment and dobutamine treatment. The observation group received conventional anti -heart failure treatment and levosimendan treatment. The treatment effects of dilated cardiomyopathy and refractory end-stage heart failure, the symptom improvement time, heart failure correction time, left ventricular ejection fraction, left ventricular end diastolic diameter, brain natriuretic peptide, cardiac index before and after intervention and drug side effects rate between two groups were compared. Results The treatment effect of dilated cardiomyopathy and refractory end -stage heart failure was higher in the observation group than that in the control group(P<0. 05). The improvement time of symptoms and the correction time of heart failure in the observation group were shorter than those in the control group(P<0. 05). The ventricular ejection fraction, left ventricular end diastolic diameter, brain natriuretic peptide, and cardiac index in two groups were similar (P>0. 05). After the intervention, the left ventricular ejection fraction, left ventricular end diastolic diameter, brain natriuretic peptide, and cardiac index in the observation group were superior to those of the control group(P<0. 05). There was no significant difference in drug side effects between the two groups, both of which were mild(P>0. 05). Conclusion Levosi-mendan has a better effect in patients with dilated cardiomyopathy and refractory end-stage heart failure than dobu- tamine does. Levosimendan can improve heart function and correct heart failure more quickly, with high drug safety, and is worth promoting.
ABSTRACT
Objective To explore the treatment of locally advanced pancreatic cancer(LAPC)by Nanoknife,and the demonstrations on contrast enhanced ultrasonography(CEUS)after the procedures. Methods Four patients were enrolled.Each of them was percutaneously inserted 3-5 Nanoknife electrodes to ablate the lesions with 2-3 sessions under the guidance of ultrasound.After the procedures,CEUS, contrast enhanced CT,contrast enhanced MRI or computed tomography angiography (CTA) were performed to assess the efficacy.Results All patients uneventfully were able to tolerate the high-voltage Nanoknife procedures.However,the endurable pain or discomfort in abdomen was complained.For one patient with obstructive jaundice and mild liver dysfunction,pancreatic amylase in serum increased slightly at the first day after treatment.Furthermore,C response protein in serum elevated,and biliary tract infection happened at the third day.Moreover,thromboses in portal and splenic vein were found at the seventh day.The survival time for all cases were 3-8 months.According to the findings of CEUS,a well-defined no contrast enhancement was detected at ablative zone for all the patients within one week.Yet, contrast enhancement was sporadically detected at the periphery in 3 patients 1-2 months late.Meanwhile, on contrast enhanced CT or MRI,an area of absent enhancement was also depicted at the ablation zone with heterogeneously decreased enhancement at periphery of the lesion.Base on CTA findings,local stenosis of splenic vein and superior mesenteric vein with varices of collateral vascularity were found in one patient at the fiftieth day,and superior mesenteric vein obstruction accompanied by varices of collateral vascularity was also found in another patient at the seventieth day.Conclusions For patients with LAPC,Nanoknife treatment is a safe and convenient procedure that can be percutaneously completed under the guidance of ultrasound.Along with enhanced CT,MRI or CTA,CEUS is a promising way to evaluate the efficacy of this procedure.
ABSTRACT
Objective: To observe the effect of needling Hegu (LI 4) on functions of the prefrontal cortex using the functional near infrared spectroscopy (fNIRS). Methods: A total of 12 healthy volunteers were randomly assigned to an acupuncture group (n=6) and a control group (n=6). The control group received no intervention. The acupuncture group received needling Hegu (LI 4) on the right side. The real-time concentration changes of oxygenated hemoglobin (HbO2), deoxygenated hemoglobin (d-Hb) and total hemoglobin (t-Hb) in the prefrontal cortex were recorded using the fNIRS, allowing for effect analysis of needling Hegu (LI 4) on the functions of the prefrontal cortex. Results: Compared with the control group, the HbO2 and t-Hb concentrations were increased in the acupuncture group and there were between-group statistical significances (bothP0.05). Conclusion: Needling Hegu (LI 4) can extensively activate the prefrontal cortex and therefore has significant effect on the functions of the brain's prefrontal cortex.

ABSTRACT
Objective To observe the efficacy of Zheng’s “gold hook fishing acupuncture” in the treatment of scapulohumeral periarthritis. Methods Sixty patients were randomly divided into gold hook fishing group and reinforcing-reducing group, with 30 cases in each group. Gold hook fishing group chose the main points from the Tianzong (SI11), Bingfeng (SI12), Jiajixue (double EX-B2), Binao (LI14), Jianyu (LI15), Jianliao (SJ14), Jianzhen (SI9), Ashi, Naoshu (SI10), Quchi (LI11), Waiguan (SJ5), Hegu (LI4), Houxi (SI3), Tiaokou (ST38) and Chengshan (BL57). Needles were pierced at tendon junction points and Ashi points, and golden hook fishing acupuncture was operated. Other points were given reinforcing-reducing method. The reinforcing-reducing group was treated with reinforcing-reducing method at points the same as gold hook fishing group. Patients were treated once a day for 2 courses, 5 days as a treatment course. The pain visual analogue scale (VAS), shoulder range of motion (ROM), and ability of daily life (ADL) were observed before and after treatment to evaluate the clinical efficacy. Results The total effective rate of gold hook fishing group was 90.0% (27/30), better than the reinforcing-reducing group 83.3% (25/30, P<0.05); VAS pain score, ROM score and ADL score before and after treatment in the two groups were improved to some extent (P<0.05), and scores in the golden hook fishing group were improved more significantly compared with reinforcing-reducing group (P<0.05). Conclusion Zheng’s gold hook fishing acupuncture can effectively improve the clinical symptoms and signs of patients with scapulohumeral periarthritis and their life quality.
ABSTRACT
@#Mesenchymal stem cells(MSCs)were derived from the early development stage of mesoderm and ectoderm and considered as one of the important members of stem cells family. Besides that, MSCs can be isolated easily and don′t have a limitation of moral and ethical problems. Moreover, MSCs can be expanded in vitro which make it possible to use in industrial preparation. Moreover, MSCs possess low immunogenicity and has the ability to home to damaged tissues, tumors, and metastases. Therefore, MSCs possess a set of fairly unique properties which make them ideally suited for clinical applications. This review summarizes the main properties of MSCs and its new progress in drug delivery system in the field of cancer therapy as a basis of further utility of engineered MSCs in the design of targeting drug delivery system.
ABSTRACT
We isolated and identified the symbiotic and adnascent microorganisms from an unidentified sponge collected from 10-meter-deep seawater of the Paracel Islands in China. A total of 16 strains were obtained and identified. Through bacteriostatic activity assay, one of the strains, Dermacoccus sp. X4, was found to effectively inhibit the growth of Staphylococcus aureus. Subsequently, its secondary metabolites were purified by silica gel partition, octadecylsilane (ODS) reverse phase, Sephadex™LH-20 size exclusion, and C18 reverse phase chromatography. Using liquid chromatography, mass spectrometry, and nuclear magnetic resonance, three of the purified compounds were structurally characterized to be one 3-(4-hydroxybenzyl) hexahydropyrrolo [1,2-a]pyrazine-1,4-dione and two indole acid glycerides. This is the first report about indole acid glyceride isolated from microbial secondary metabolites, enriching marine drug candidate resources.

ABSTRACT
Objective To analyze the genetic characteristics of echovirus type 25( Echo25) strains isolated from patients with viral encephalitis in Longyan city. Methods Cerebrospinal fluid(CSF) specimens were collected from hospitalized patients with viral encephalitis or central nervous system infection in Longyan,2012. Enteroviruses(EV)were isolated from the specimens and then identified. Four strains of Echo25 were screened out by using serum neutralization test. Coding sequence of the VP1 region of the 4 Echo25 strains were amplified by RT-PCR and then sequenced. A phylogenetic tree was constructed to ana-lyze the nucleotide sequence homology between those sequences and the sequences of reference Echo25 strains available in the GenBank database. Results The VP1 nucleotide sequences of Echo25 strains isola-ted in Longyan were 498 bp in length,encoding 166 amino acid residues. The homology analysis showed that the VP1 nucleotide sequences of 3 strains were identical,sharing 97% homology in nucleotide with the rest strain. The Echo25 strains isolated in Longyan were highly similar to KJ957190( Beijing,2010)and HM031189(Henan,2008)strains. Phylogenetic analysis revealed that the Echo25 strains isolated in Longyan belonged to genotype B1. Conclusion Echo25 was one of the pathogens causing viral encephalitis in Longyan in 2012 and different transmission chains of Echo25 had emerged. This study indicates that it is necessary to strengthen the surveillance for EV and understand the genetic variation of the Echo25 for provi-ding better supportive evidences for the prevention and control of related diseases.
ABSTRACT
‘Warming-dredging needling technique’ is one of the specific needling techniques created by Prof. Zheng Kui-shan for treating intractable and difficult diseases. Developed from ‘Shao Shan Huo (Mountain-burning Fire)’ and ‘warming- reinforcing method’, this method displays the effects of ‘warming’, ‘dredging’ and ‘reinforcing’. The ‘scapula-penetrating heat’ and ‘eye-transmitting heat’ belong to the representative needling techniques of ‘warming-dredging needling technique’. In order to promote the clinical application of ‘warming-dredging needling technique’, its theoretical foundation and clinical experience are summarized.
ABSTRACT
Objective To investigate the effects of maternal behaviors in the rats with neuropathic pain (NP) on emotions of offspring rats and the relationship with DNA methylation in the amygdala.Methods Forty-eight healthy adult Sprague-Dawley rats (24 males and 24 females),weighing 200-250 g,were used in the study.Twelve female and 12 male rats were randomly selected,and NP was induced by chronic constriction injury (CCI).Each female rat was mated with one male rat at 10 days after CCI.Fortyeight F1 generation rats of maternal rats with NP were randomly divided into 2 groups (n =24 each) using a random number table:NP1 group and NP2 group.Forty-eight F1 generation rats of normal maternal rats were randomly divided into 2 groups (n=24 each) using a random number table:S1 group and S2 group.The F1 generation rats were cross-fed immediately after birth between group NP2 and group S2,and fed by their own mother rats in NP1 and S1 groups.All the offspring rats were fed to 21 days after birth by the maternal rats selected,and separately fed to 30 days after birth,and then subjected to behavioral testing.Retrieving and licking pups were recorded after delivery in maternal rats to evaluate the maternal behaviors.The mechanical and thermal paw withdrawal thresholds were measured in the offspring rats.Elevated plus maze and open field tests were conducted to detect anxiety and depression behaviors in the offspring rats.At 1 day after completion of behavioral testing,the expression of DNA methyltransferase 1 (DNMT1) and DNA methyltransferase 3a and 3b in the amygdala was detected by Western blot analysis.Results Compared with S1 or S2 groups,the latency to lick pups,latency to retrieve pups,and total retrieval time were significantly prolonged,and the total time spent licking pups was significantly shortened in NP1 group or NP2 group (P<0.05 or 0.01).There was no significant difference in the mechanical and thermal paw withdrawal thresholds in the offspring rats between the four groups (P>0.05).Compared with group S1,the ratios of time spent in the open arm to the closed arm and of time spent in the central square to the peripheral square were significantly decreased,DNMT1 expression in the amygdala was significantly up-regulated,and the total DNA methylation was increased in the offspring rats in S2 and NP1 groups (P<0.05).Compared with group NP2,the ratios of time spent in the open arm to the closed arm and of time spent in the central square to the peripheral square were significantly decreased,DNMT1 expression in the amygdala was significantly up-regulated,and the total DNA methylation was increased in the offspring rats in S2 and NP1 groups (P<0.05).Conclusion Decreased maternal behaviors in the rats with NP results in negative emotions including anxiety and depression in the offspring rats,and the mechanism is related to increased DNA methylation in the amygdala of the offspring rats.
ABSTRACT
This study aimed to analyse the genetically characterize isolates of Echovirus 11 from Longyan City,Fujian Province,and to reveal their genetic relationships with other isolates from China and abroad. Cerebrospinal fluid specimens from patients diagnosed with viral encephalitis or central nervous system (CNS) infections were collected from Longyan First Hospital between January and December 2011. Seven Echo11 strains were isolated and identified using the RIMV serum panel. The entire VP1 coding regions of four strains were sequenced and typed as Echo11 by an online blast program and,subsequently, phylogenet- ic analyses of the VP1 sequences of these stains and others published on GenBank were conducted. There were 600 nucleotides (nt) in each complete VP1 coding region that encoded 200 amino acids (aa). Among those four Echo11 strains, the sequence identities of nt and aa were 100% and 99%-100% respectively. And phylogenetic analyses indicate belong to subtype DS, the homology compared with DS strain (GU393713) were 93% (nt) and 99% (aa). The sequence identities for the nt and aa were 75%-76% and 90%, respectively, between the current isolates from Longyan and the Gregory prototype strain found in 1953. The sequence identity of nt and aa between the Longyan virus strains and the domestic Shandong strains isolated in 2010 were lower, at 74% and 88%-89%, respectively. However,the highest level of ho- mology was found when the Longyan strains were compared with the Netherlands strain (GU393773) found in 2007 (nt and aa identity: 94%-95% and 98%-99%, respectively). The relatively low levels of similarity between domestic isolates suggest that different transmission routes exist for Echo11 in mainland China.

BACKGROUND:The living standard of farmers and herdsmen in Xinjiang Uygur Autonomous Region, China is significantly lower than that of urban residents in general. Meanwhile, the shortage of doctors and medicines and lack of medical knowledge are the main reasons for local farmers and herdsmen to suffer from knee osteoarthritis. Most of the farmers and herdsmen are not aware of or prevent knee osteoarthritis in the early days to remove pathogenic factors, which results in a serious condition at the time of their medical treatment. OBJECTIVE: To investigate the main pathogenic factors of knee osteoarthritis in Uygur, Kazakh and Han populations in pastoral areas of northern Xinjiang Uygur Autonomous Region, China.METHODS:The permanent residents of Uygur, Kazakh and Han ethnic groups in northern Xinjiang, China who met the criteria were selected by the method of stratified, multistage and cluster random sampling during June 2012 to October 2014. The investigation of knee osteoarthritis was conducted among al the residents who meet the inclusion criteria using the method of home scene closed questionnaire. X-ray lateral plain film examination of the knee joint was performed among the patients presenting with the symptoms of knee osteoarthritis. The database was established. The multi-factor and unconditional Logistic regression analysis was conducted among the 40 variables using SPSS 20.0 software. RESULTS AND CONCLUSION:The 3 402 of 3 540 questionnaires were valid. The Logistic regression analysis suggest that the common pathogenic factors in Han, Uygur and Kazakh ethnic groups are associated with older ages, female gender, high body mass and drink alcohol. Smoking, history of internal disease, high education level, standing position, climbing, trauma, family history, fried food, housing conditions and amenorrhea, different nationalities, churchgoing of ethnic minorities are also the major risk factors. Among the three ethnic groups, the prevalence of female patients in Uygur and Kazak ethnic groups is significantly higher than that of Chinese Han nationality. The morbidity is different among these three nationalities. The dietary preferences cannot be determined as the related influencing factor of knee osteoarthritis. Whether the means of transportation, residence climate and environment, the number of pregnancies and deliveries, drinking tea or not, the type of tea are related to knee osteoarthritis remains unclear.
