Objective To compare with the effect of high-frequency repetitive transcranial magnetic stimulation (rTMS) between the left and the right prefrontal on refractory negative symptoms and serum brain-derived neurotrophic factor (BDNF). Methods 80 hospitalized schizophrenics with refractory negative symptoms were divided into study group (n=40) and control group (n=40) randomly. Both groups were received 4-week treatment of 10 Hz rTMS. The stimulus lo?cation of the study group was the left prefrontal, and the control group was the right prefrontal. The type and dose of anti?psychotics remained unchanged during the treatment. The evaluation of positive and negative symptom scale (PANSS) and the measurement of BDNF concentration before treatment and after 4 weeks treatment was analyzed. Results Com?pared with before treatment, the total score of PANSS after treatment significantly decreased (P<0.05) both in the study group [(71.2±13.8) vs. (63.3±11.4)] and the control group [(70.3±13.4) vs. (63.7±12.2)]. The score of negative symptoms in the study group decreased [(22.8±6.6) vs. (18.4±5.9), P<0.01]. The BDNF concentration increased in the study group ](6.78±2.16) vs. (8.74±2.76)] and the control group [(6.83±2.32) vs. (8.66±2.70)]. Conclusion 10Hz rTMS on the left pre?frontal combined with drugs are helpful to improve the refractory negative symptom of the patients with schizophrenia. Stimulation on both left and right prefrontal lobe could increase serum BDNF concentration.

Objective To investigate the effects of comprehensive psychological intervention on psychological and biochemical indexes of servicemen in three degree combat readiness. Methods 189 servicemen in three degree combat readiness were randomly divided into the study group and the control group by squad. Beyond the same exercise and education as the control group, the study group received the comprehensive psychological intervention in the course. They were all assessed with Self-rating Depression Scale (SDS) ,self-rating anxiety scale (SAS) ,and simplified coping style questionnaire (SCSQ) at the day entering three degree combat readiness (prereadiness) and the next day after the mission (post-readiness). The serum concentrations of superoxide dismutase ( SOD), malondialdehyde ( MDA), cortisol ( COR), and aldosterone (ALD) were determined to evaluate biochemical indexes at the same time. Results Compared with the control group after the combat readiness, the total scores of SDS( (42.1 ± 9.3 ) vs (49.2 ± 10.3 ) ) and SAS( (43.8 ± 7.2) vs (50.6 ± 10.2), P< 0. 01 ) were lower, the score of the positive coping style ( ( 21.2 ± 6.4) vs ( 18.2 ± 5.4), P < 0. 05 ) was higher in the study group.Meanwhile,the levels of MDA( (2.6 ±0.51 ) μmol/L) ,COR( (252.5 ±52.4) ng/ml) ,and ALD ( (97.5 ±24.4) pg/ml) were lower ( P < 0. 01 ), the activity of SOD ( ( 1551 ± 354 ) U/gHb) was higher ( P < 0. 01 ) after the combat readiness. In the control group post-readiness, the total scores of SDS (49.2 ± 10.3) and SAS (50.6± 10.2) ,the levels of MDA ( (2.9 ±0.35 ) μmol/L) ,COR( (333.8 ±62.6) ng/ml) ,and ALD( ( 123.8 ±29.6)pg/ml ) increased significantly (P<0.01), the score of the positive coping style ( 18.2 ± 5.4) and the activity of SOD ( 1302 ± 352 ) U/gHb decreased significantly ( P < 0. 01 ). The total scores of SDS, SAS were negatively related to the level of SOD ( r= -0. 142, -0. 119, P<0. 0lor 0.05) ,and positively related to COR ( r=0. 156,0. 159, P<0. 01 ) and ALD ( r=0.151,0.156, P<0. 01 ). The score of positive coping style was positively related to the level of SOD ( r=0. 141, P<0. 01 ) ,and negatively related to COR and ALD ( r= -0. 152, -0. 155, P< 0. 01 ). Conclusion Comprehensive psychological intervention could effectively improve the psychological and biochemical indexes,reduce the stress level of servicemen in three degree combat readiness.

Antibody drugs often show "heterogeneity",including the related isomers differing from one another in glycosylation,charge or molecular size.Most of these isomers come from post-translational modifications,such as aggregation,degradation,glycosylation,oxidation,deamidation or disulfide misfolding,of the recombinant protein in the "cell factories".These modifications not only influence the quality,safety and efficacy of the antibodies,but also serve as an important indication of product quality throughout the whole process of antibody production.This paper reviews the relationship between glycoslation,charge and size heterogeneities of monoclonal antibodies and drug efficacy,safety,pharmacokinetics as well as immunogenicity,contributing to a better understanding of the relationship between antibody structure and function.It will provide some support and guidance for the research and development of antibody drugs,especially biosimilars.

Objective This study is to explore the association between self-differentiation and men-tal health among medical students. Methods Differentiation of self inventory-revised (DSI-R) and univer-sity personality inventory (UPI) were used to measure the self-differentiation and mental health of 526 med-ical students from Grade One to Grade Five at a comprehensive university in Shanghai. Result The mean score of DSI-R was (171.25±19.65). 32.2% of participants had different levels of mental health prob-lems. Female students got higher score of DSI-R than male students (P=0.007). Statistically significant dif-ferences of medical students' self-differentiation were found among years of school attended (P=0.039). Sta-tistically significant differences of self-differentiation were also found between the first class and the third class of UPI (P<0.001) as well as the second class and the third class of UPI (P=0.004). Ordinal regression analysis indicated that self-differentiation was a risk factor for medical students' mental health (OR=1.036, P=0.000). Conclusion The average score of medical students' self-differentiation was higher than college students of other specialties. But their mental health condition was worse. Medical students with higher self-differentia-tion had worse mental health situation.

Objective:To explore the effect of swallowing different viscosities and volumes on the swallowing of dysphagic stroke survivors, and also penetration and aspiration.Methods:A total of 59 stroke survivors with dysphagia were evaluated using videofluoroscopy while completing the Chinese version of the volume viscosity swallow test. They were required to swallow 3, 5 and 10ml of food of medium, low, zero and high viscosity. Modified barium swallowing impairment profiles (MBSImPs) and the Rosenbek penetration aspiration scale were used for quantitative analysis.Results:Tongue control, initiation of the pharyngeal swallow and larynx closure showed the worst performance when swallowing zero-viscosity food. Oral residue performance was poor when swallowing large volumes and pharyngeal peristalsis was poor with small volumes. The risk of penetration and aspiration was greater with low-viscosity, large-volume swallowing tasks. There was a significant positive correlation between the penetration aspiration grade and total pharyngeal score. Larynx closure was especially strongly correlated with the penetration aspiration grade.Conclusions:The characteristics of physiological swallowing are closely related to the viscosity and volume of the material being swallowed. The risk of penetration and aspiration is greater with large volumes of low-viscosity food.

Objective:To explore the incidence and severity of esophageal clearance impairment in stroke survivors with dysphagia, the clinical characteristics of patients with abnormal esophageal clearance, and their relationship with swallowing physiology, penetration and aspiration.Methods:Clinical data were collected describing 174 stroke survivors whose swallowing had been studied videofluoroscopically. In each selected case there was a good anterior-posterior view of esophageal clearance. Their anterior-posterior and lateral imaging results while swallowing 5ml of high-consistency food were analyzed. The esophageal clearance item of the modified barium swallow impairment profile was then used to rate each subject′s esophageal clearance and each physiological component of swallowing in the oral and pharyngeal phases. The Rosenbek penetration aspiration scale was employed evaluate the safety of their swallowing.Results:Seventy of the patients (40.2%) displayed abnormal esophageal clearance, and more than half of the 70 (43 patients, 24.7%) showed mid- to distal esophageal retention. Those with abnormal esophageal clearance had a higher average age and more severe overall impairment in the pharyngeal phase of swallowing. Esophageal clearance was not, however, significantly correlated with swallowing physiology in the oral phase or with penetration or aspiration grade. There were, however, significant positive correlations with laryngeal elevation, anterior hyoid excursion, pharyngeal stripping waves, pharynx contraction, upper esophageal sphincter opening, tongue base retraction and pharyx residue.Conclusion:Stroke survivors with dysphagia may display abnormal esophageal clearance. The risk is closely related to age and the severity of the dysphagia. Abnormal physiology during the pharyngeal phase of swallowing and reduced pharyngeal stripping may predict abnormal esophageal clearance. Swallowing assessment can be made more comprehensiveness and systematic by incorporating anterior-posterior videography in routine barium swallowing studies.
