Spasticity can influence the outcome of the patients with cerebral injury. Most traditional physical therapies often focused on the spastic muscle. The recent development has showed that stimulating the antagonistic muscle can relieve the spasticity, which based on the reciprocal inhibition theory. This paper reviewed these approaches on its theory and application.

Objective To investigate the state of perceived stigma,self-efficacy and quality of life of patients with mental disorders,and analyze the relationship among these variables,and explore the mediating effect of self-efficacy between the perceived stigma and quality of life.Methods Totally 406 patients with mental disorders were assessed with the Perceived Devaluation-Discrimination Scale (PDDS),Self-efficacy Scale (SES) and Schizophrenia Quality of Life Scale (SQOLS).Results The average score of PDDS was (2.44±0.36).The average score of GSES was (25.75±7.31).The perceived stigma,self-efficacy and quality of life were significantly correlated with each other.The self-efficacy played a mediating role between perceived stigma and quality of life.Conclusions The self-efficacy is the intermediary variable of perceived stigma and QOL of patients with mental disorders.

Objective To explore the effect of self-confidence training on social anxiety and self-esteem of patients with social anxiety disorder.Methods 80 patients with social anxiety disorder were randomly divided into the study group and the control group.The study group was given the Self-confidence Training twice a week for five weeks and the control group was not given any training.Social Anxiety Subscale of the Self-Consciousness Scale and Self-Esteem Scale were used to evaluate the effect before the intervention and after the intervention for three months,six months.Results The social anxiety and self-esteem had significant differences between the two groups (F=20.422,P＜0.001 ; F=11.239,P=0.001),they had a tendency to change over time (F=120.080,P＜0.001 ; F=143.503,P＜0.001),and the role of the time factor was different between two groups (F=18.777,P ＜0.001 ; F =24.864,P＜0.001).Further pairwise comparisons revealed that the study group showed significantly decrease in social anxiety ((10.00 ± 3.05) vs (13.42 ± 2.76),(9.53 ± 3.72) vs (13.21± 2.48)) and improvement in score of self-esteem((28.75 ± 4.19) vs (24.27 ± 3.84),(29.50 ± 4.85) vs (24.15 ±3.55)) than control group on post-test and delayed-test (P＜0.001).Conclusion Self-confidence training can reduce social anxiety and improve self-esteem for patients with social anxiety disorder.

Objective To investigate the influence of stigma on QOL of patients with mental disorders.Methods By using Link stigma series scale and schizophrenic quality of life scale,we assessed and analyzed 406 psychiatric patients′stigma and QOL, as well as the correlation and influence between them.Results The score of perceived devaluation-discrimination dimension of the stigma scale had positive correlation with total score of QOL,score of psycho-social dimension and score of motivation and energy dimension (P <0.05).The scores of challenge dimension and separation dimension in the stigma scale had positive correlation with motivation and energy dimension of the QOL scale (P <0.05).Regression analysis showed that stigma did not have influence on QOL of patients with mental disorders.Conclusion Stigma in psychiatric patients has no significant influence on QOL,but correla-tion relationship exists between them.The higher score of perceived devaluation-discrimination dimension,challenge dimension and separation dimension of stigma scale,the poor QOL the patient would have.

Objective To observe the effects of Salvia injection on the brain pathology,expression of synaptophysin and the synaptic ultrastructure at different time points in neonatal rats after hypoxic-ischemic brain damage (HIBD).Methods One hundred and fifteen healthy newborn SD rats of 7-day-old were randomly divided into normal group,sham group,Salvia high dose group,Salvia low dose group,and the HIBD model group.The HIBD model was prepared by ligation of the left carotid artery combined with hypoxic environment.The rats(in normal group,sham and HIBD model groups) were injected with sterile saline[9.0 mL/(kg · d)],while the rats in high and low dose groups were injected with Salvia injection [9.0 mL/(kg · d) and 4.5 mL/(kg · d) respectively].The intraperitoneal injec tion lasted for 7 and 14 days.The rats' brains were collected at one day,7 days and 14 days after the modeling respec tively.The specimens of brain tissue were observed through hematoxylin-eosin (HE),the expression of synaptophysin (SYP) was determined by using immunohistochemistry method,and the synaptic ultrastructure in the frontal cortex was observed through transmission electron microscope.Results Finally,106 newborn rats were included in statistics analysial.(1)General observation:after HIBD modeling,the neonatal rats were mostly in the left-lateral position,with difficulties in turning over,balance abnormalities,limb shaking and other abnormal behaviors,and the delay of eyes open with the left upper eyelid ptosis.(2) Pathology:the disordered and deep stained nerve cells,the degenerated and necrotic neurons were observed in the brain tissues of the HIBD model group.(3) Expression of synaptophysin:mean density of SYP in the HIBD model group was significantly lower than the normal group on day 1,day 7,and day 14 (P ＜0.05);the SYP expression in the Salvia intervention groups increased compared with the HIBD model group(P ＜ 0.05).(4) Synaptic ultrastructure:the incomplete structure of the frontal cortex neurons,the swelling organelle and the synaptic structure damage were observed in the HIBD rats.Compared with the HIBD model group,the neuronic and synaptic ultrastructure were improved by the intervention treatment of high and low dose Salvia injection.Conclusions The mechanism of Salvia injection in treatment of neonatal rats with HIBD may be associated with the improvement in neuronal ultrastructure and synaptic reorganization.

Objective: To investigate the current prevalence of latent tuberculosis infection (LTBI) among residents living in Nanchuan District, Chongqing Municipality, so as to provide the evidence for formulating LTBI control measures. Methods: The residents living in one street and one township from Nanchuan District were randomly selected using the multistage cluster sampling method during the period between January and April, 2020, and their demographic information, smoking history, history of alcohol consumption, history of contacts with tuberculosis patients and Bacillus Calmette-Guérin ( BCG ) vaccination scars were collected. The infection of Mycobacterium tuberculosis was detected using interferon gamma release assay ( IGRA ), and a positive IGRA test and exclusion of active tuberculosis was defined as LTBI. The prevalence of LTBI was descriptively analyzed among the study subjects. Results: Totally 1 000 residents were recruited, including 381 males and 619 females, with a male to female ratio of 0.62∶1. The mean age was ( 45.87±18.40 ) years. Among all participants, there were 222 smokers ( 22.20% ), 247 subjects consuming alcohol (24.70%), 62 subjects with a history of contacts with tuberculosis patients ( 6.20% ) and 904 subjects with BCG scars ( 90.40% ). A total of 198 residents were diagnosed with LTBI (19.80% prevalence), and a higher prevalence rate of LTBI was seen in men than in women ( 23.36% vs. 17.61%; χ2=4.911, P=0.027 ). The prevalence of LTBI was significantly higher in married/divorced/widowed residents than in unmarried residents ( 24.22% vs. 2.01%; χ2=49.514, P<0.001 ), and significantly greater prevalence was found in smokers than in non-smokers ( 27.93% vs. 17.48%; χ2=11.871, P=0.001 ). The prevalence of LTBI appeared a tendency towards a rise with age ( χ2trend=59.100, P<0.001 ) and body mass index ( χ2trend=9.479, P=0.002 ). Conclusions The prevalence of LTBI is high among residents living in Nanchuan District, notably among elder, male smokers with high body mass index. Risk monitoring and timely interventions are required.

Objective To observe the effect of tetrahydroxy stilbene glucoside (TSG) on the behavior on rat model and the expressions of autophagy-associated protein Beclin-1 and LC3- Ⅱ induced by Aβ1-42 Methods Eighty rats were equally randomized into 4 groups (n =20):The control group,the sham operated group,the model group and the TSG group.The behavior of rats was measured by using Y-maze and Morris water maze.The expression of Beclin-1 and LC3- Ⅱ in rats hippocampus was detected by Western blot and RT-PCR at the time points.Results The number of electric-stimulus in hippocampus significantly increased and the Morris water maze test showed that the escape latency prolonged,swimming distance increased and the times of crossing the exact former platform location decreased both in the model and TSG groups after 21 days compared with those in control group.The mRNAs and protein expressions of Beclin-1 (0.51 ±0.03)and LC3-Ⅱ (0.68 ± 0.04) in model group were higher than that in control group (0.31 ± 0.01,0.31 ± 0.02) at that time point ( Beclin-1:t =28.2843,P ＜ 0.05 ; LC3- Ⅱ :t =37.0000,P ＜0.05).Compared to model group,the expression of the Beclin-1 and LC3- Ⅱ was decreased at 21 d in TSG group (Beclin-1:t =9.8387,P ＜ 0.05 ; LC3- Ⅱ :t =16.2698,P ＜ 0.05 ).Conclusions Autophagy self-regulated system is started through the increased expressions of Beclin-1 and LC3- Ⅱ after Aβ deposition in rats,so as to attenuate cerebral injury caused by Aβ neurotoxicity.Autophagy pathway is possible one of the mechanisms in Aβ neurotoxic injury. Tetrahydroxy stilbene glucoside from polygonum multiflorum has protective effect on it.

Objective To investigate the flora distribution and drug resistance status in the Affiliated Hospital of Academy of Military Medical Sciences so as to provide experimental data for clinical doctors to use antibiotics more efficiently.Methods The clinical data of pathogenic bacterial infections over nearly one year in our hospital were retro -spectively analyzed .Results There were 3815 strains of pathogenic bacteria isolated from the sample .The percentage of Gram-positive strains was 36.4%while that of Gram-negative bacteria was 63.6%.The most common bacteria were Esche-richia coli, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa and Staphylococcus epidermidis.In terms of drug tolerance , Enterobacteriaceae remained highily sensitive to carbapenems .The total resistance rate was 2%-5%.The resistance rate of A.baumannii to meropenem and imipenem was 60%.There were still a few pan-drug resistant strains among K.pneumoniae,A.baumannii and P.aeruginosa,but there were no drug resistant strains to vancomycin , tige-cycline and linezolid in Staphylococcus.The resistance rate of Enterococcus faecium to vancomycin was 9%.The bacteria were distributed predominantly in ICU ,Department of Hematology and Department of Oncology .The samples were mainly composed of phlegm specimens .Conclusion The high distribution in the three departments mentioned above is largely re-lated to the diseases being treated .The specimens from the lower respiratory tract show more types of bacteria that are mostly drug-resistant, and the isolating rate of vancomycin resistant Enterococcus and carbapenems resistant K.pneumoniat is com-paratively high .

Many researchers employed mammalian expression system to artificially express cannabinoid receptors, but immunoblot data that directly prove efficient protein expression can hardly be seen in related research reports. In present study, we demonstrated cannabinoid receptor protein was not able to be properly expressed with routine mammalian expression system. This inefficient expression was rescued by endowing an exogenous signal peptide ahead of cannabinoid receptor peptide. In addition, the artificially synthesized cannabinoid receptor was found to aggregate under routine sample denaturing temperatures (i.e., [Symbol: see text]95°C), forming a large molecular weight band when analyzed by immuno-blotting. Only denaturing temperatures [Symbol: see text]75°C yielded a clear band at the predicted molecular weight. Collectively, we showed that efficient mammalian expression of cannabinoid receptors need a signal peptide sequence, and described the requirement for a low sample denaturing temperature in immuno-blot analysis. These findings provide very useful information for efficient mammalian expression and immuno-blotting of membrane receptors.
