BACKGROUND: In recent years, ultrasound microbubble gene transfer system has been applied for gene transfection in many parts of the body, but it has been seldom reported to be used for gene transfection in bone parts. OBJECTIVE: To investigate the efficiency and feasibility of ultrasound-targeted microbubble destruction applied for transfection of enhanced green fluorescent protein plasmid into the femoral head of rabbits.METHODS: Japanese big-ear rabbits were randomly divided into five groups: bare transfection, pre-irradiation + bare transfection, ultrasound transfection, pre-irradiation+ultrasound transfection, and repeatable transfection. In the first two groups, ultrasound-targeted gene transfection and irradiation was not used, but in the latter three groups, ultrasound-targeted microbubble destruction was used to transfect enhanced green fluorescent protein (EGFP) plasmid into the femoral head of rabbits. At 1 week after transfection, EGFP expression in femoral head was observed under the fluorescence microscope. RESULTS AND CONCLUSION: EGFP expression appeared in the ultrasound transfection, pre-irradiation + ultrasound transfection and repeatable transfection. The transfection efficiency of EGFP plasmid was significantly higher in the repeatable transfection group than in the other groups (P < 0.01). Obvious injury loci were not observed in the soft tissue and bone tissue slices of ultrasonic irradiation parts in the ultrasound transfection, pre-irradiation + ultrasound transfection and repeatable transfection groups. These results confirm that ultrasound-targeted microbubble destruction is a safe and effective method to transfect EGFP plasmid into the femoral head of rabbits.

Objective To investigate the capability of empathy for pain in bipolar disorder (BD). Methods Thirty-two patients with BD (16, 8 and 8 in depressed, manic and remitted phases, respectively) and 32 healthy controls matched for age, gender and education were recruited. Empathy for pain paradigm were used. Subjects were required to judge whether the person in the picture felt painful and rate pain degree regarding to painful and neutral pictures. Accuracy, reaction time and ratings of pain degree were used as indicators of empathy for pain. Chinese version of Interpersonal Reactivity Index (IRI-C) were used to measure empathy. Results Compared to controls, accuracy of painful pictures was significantly lower in patients [(0.74±0.16) vs.(0.83±0.10), P<0.05]. Reaction time for both painful [(903.84±167.49) ms vs. (765.06±108.21) ms] and neutral [(880.44 ± 190.36) ms vs. (750.31 ± 103.15)ms] pictures were significantly longer in patients (P<0.05). Pa?tients showed lower scores in factors of perspective taking [(9.20±5.43) vs. (12.43±4.13)], fantasy [(11.85±4.57) vs. (15.50± 5.56)] and empathy concern [(14.59±5.35) vs. (17.63±3.37)] in IRI-C (P<0.05). Accuracy of painful pictures was positively correlated with scores in fantasy (r=0.37, P=0.04) and reaction time was positively correlated with duration of disease in pa?tients (r=0.64, P<0.01). Conclusion Bipolar disorder has deficit in the capability of empathy for pain.

Objective:To study the neurodevelopmental prognosis and risk factors for adverse outcomes of neonatal seizure.Methods:From December 2019 to November 2020, infants with neonatal seizure diagnosed in our hospital were enrolled in this retrospective study. Based on survival or not, mental development index (MDI), psychomotor development index (PDI) and seizure episodes at the age of 12 months, the infants were assigned into adverse outcome group and normal outcome group. The risk factors for adverse outcomes were statistically analyzed.Results:A total of 75 infants were enrolled,including 39 cases in adverse outcome group and 36 in normal outcome group. 69 cases showed abnormal amplitude-integrated electroencephalogram(aEEG), including 38 mildly abnormal cases,23 moderately abnormal cases and 8 severely abnormal cases, The incidences of adverse outcomes and mortality rates were significantly different ( P<0.05) among infants with different severity levels of aEEG abnormalities and the severity levels of aEEG abnormalities were positively correlated with adverse outcomes ( r=0.367, 0.471, P<0.05).Univariate analysis showed that adverse outcome group had significantly higher incidences of chorioamnionitis, seizure onset age ≤3 d, 5 min Apgar score ≤3, cranial ultrasound abnormalities, brain MR abnormalities and aEEG abnormalities than normal outcome group ( P<0.05).Logistic regression analysis showed that seizure onset age ≤3 d ( OR=3.988, 95% CI 1.376-11.674), abnormal brain MR ( OR=3.296, 95% CI 2.383-17.377) and bilirubin encephalopathy ( OR=3.792,95% CI 2.110-13.216) were independent risk factors for adverse outcomes of neonatal seizure. Conclusions:For neonatal seizure, the infants with more severe abnormal aEEG will have higher incidences of adverse outcomes and mortality. Seizure onset age ≤3 d, brain MR abnormalities and bilirubin encephalopathy were independent risk factors for adverse outcomes of neonatal seizure.

Objective To explore the development and clinical effect of weight_adjustable suit for children with dyskinetic cerebral palsy. Methods Twenty_six cerebral_palsy children with involuntary movement admitted to the Third Hospital Affiliated to Jiamusi University from March to October 2016 were randomly divided into the observa_tion group and the control group,13 cases in each group. The control group was treated with routine rehabilitation trai_ning. The observation group was put on adjustable heavy clothes besides conventional rehabilitation. Before and after treatment,childrenˊs functional independence and gross motor function were assessed and compared by using Wee Punc_tional Independence Measure(Wee_PIM)and Gross Motor Punction Rating Scale(GMPM_88). Results After treat_ment the Wee_PIM score of the control group was(43. 24 ± 5. 58),the GMPM score was(61. 81 ± 9. 46),the Wee_PIM score of the observation group was(50. 21 ± 6. 03),and the GMPM score was(65. 73 ± 10. 17). There were sig_nificant differences between the two groups(P〈0. 05),while the scores of the observation group were significantly higher than those of the control group,and the difference was significant(t﹦2. 582,2. 346,all P〈0. 05). Conclusions The adjustable heavy suit can effectively improve the functional independence and gross motor function of cerebral palsy children with involuntary movement and their comprehensive ability,and it is worth trying clinically.

Heme is a key cofactor in aerobic life, both in eukaryotes and prokaryotes. Because of the high reactivity of ferrous protoporphyrin IX, the reactions of heme in cells are often carried out through heme-protein complexes. Traditionally studies of heme-binding proteins have been approached on a case by case basis, thus there is a limited global view of the distribution of heme-binding proteins in different cells or tissues. The procedure described here is aimed at profiling heme-binding proteins in mouse tissues sequentially by 1) purification of heme-binding proteins by heme-agarose, an affinity chromatographic resin; 2) isolation of heme-binding proteins by SDS-PAGE or two-dimensional electrophoresis; 3) identification of heme-binding proteins by mass spectrometry. In five mouse tissues, over 600 protein spots were visualized on 2-DE gel stained by Commassie blue and 154 proteins were identified by MALDI-TOF, in which most proteins belong to heme related. This methodology makes it possible to globally characterize the heme-binding proteins in a biological system.

We report a complete genomic sequence of rare isolates (minor genotype) of the SARS-CoV from SARS patients in Guangdong, China, where the first few cases emerged. The most striking discovery from the isolate is an extra 29-nucleotide sequence located at the nucleotide positions between 27,863 and 27,864 (referred to the complete sequence of BJ01) within an overlapped region composed of BGI-PUP5 (BGI-postulated uncharacterized protein 5) and BGI-PUP6 upstream of the N (nucleocapsid) protein. The discovery of this minor genotype, GD-Ins29, suggests a significant genetic event and differentiates it from the previously reported genotype, the dominant form among all sequenced SARS-CoV isolates. A 17-nt segment of this extra sequence is identical to a segment of the same size in two human mRNA sequences that may interfere with viral replication and transcription in the cytosol of the infected cells. It provides a new avenue for the exploration of the virus-host interaction in viral evolution, host pathogenesis, and vaccine development.
