Effect of Yunkang Oral Solution on pregnant mice with spleen deficiency syndrome / 中国中药杂志

This study aimed to investigate the therapeutic effect of Yunkang Oral Solution on the improvement of spleen deficiency and pregnancy outcomes in pregnant mice with spleen deficiency syndrome induced by irregular diet and over consumption of cold and bitter foods. To simulate human irregular diet and over consumption of cold and bitter foods leading to spleen deficiency, the pregnant mice with spleen deficiency syndrome were prepared using an alternate-day fasting and high-fat diet combined with oral administration of Sennae Folium. During the experiment, spleen deficiency-related indicators and diarrhea-related parameters were measured. Gastric and intestinal motility(gastric emptying rate and intestinal propulsion rate) were evaluated. The levels of serum ghrelin, growth hormone(GH), gastrin(Gas), total cholesterol(TC), low-density lipoprotein cholesterol(LDL-c), chorionic gonadotropin β(β-CG), progesterone(P), and estradiol(E_2) were measured. Intestinal barrier function in pregnant mice with spleen deficiency syndrome was assessed. Conception rate, ovarian coefficient, litter-bearing uterine coefficient, number of live fetuses, average fetal weight, and fetal length were calculated. The results showed that Yunkang Oral Solution significantly improved spleen deficiency-related indicators and diarrhea in pregnant mice with spleen deficiency syndrome, increased gastric emptying rate and intestinal propulsion rate, elevated the levels of gastrointestinal hormones(ghrelin, GH, and Gas) in the serum, and reduced lipid levels(TC and LDL-c), thereby improving lipid metabolism disorders. It also improved colonic tissue morphology, increased the number of goblet cells, and promoted the mRNA and protein expression of occludin and claudin-1 in colonic tissues, thereby alleviating intestinal barrier damage. Yunkang Oral Solution also regulated the levels of pregnancy hormones(β-CG, P, and E_2) in the serum of pregnant mice with spleen deficiency syndrome. Moreover, it increased the conception rate, ovarian coefficient, litter-bearing uterine coefficient, number of live fetuses, average fetal weight, and fetal length. These findings suggest that Yunkang Oral Solution can improve spleen deficiency-related symptoms in pregnant mice before and during pregnancy, regulate pregnancy-related hormones, and improve pregnancy outcomes.

The correlation of developing capability of autistic children with social and linguistic parenting behaviors / 中华行为医学与脑科学杂志

Objective:To investigate the correlation between social and linguistic parenting behaviors and developing capability of children with autism.Methods:From August 2020 to December 2020, the social and linguistic parenting behaviors of 302 parents of children diagnosed with autism were investigated in the outpatient department of the hospital.Meanwhile, the data of Gesell scale for children, the social life competence scale for infant and junior middle school students, the autism behavior checklist and the Cancy autism behavior scale were collected.SPSS 20.0 software was used for statistical analysis.Independent sample t test and analysis of variance were used to compare the social and linguistic parenting behaviors of different parents.Pearson correlation analysis was used to analyze the correlation between the social and linguistic parenting behaviors of parents and children's developmental ability and symptom severity. Results:There were no statistically significant differences in children's social and language development parenting behavior between father and mother ( t=1.033, P=0.303; t=-0.312, P=0.756). There were no statistically significant differences in children's social and linguistic parenting behaviors between fathers of different age groups ( F=1.425, P=0.244; F=1.127, P=0.345). Among mothers of different age groups, the social parenting behaviors of <30 years old and 30-34 years old groups were significantly better than those of 35-39 years old group ( F=3.374, P=0.019; LSD: P=0.010, P=0.006). Among fathers, the social parenting behavior( F=4.346, P=0.008; LSD: P=0.020, P=0.001) and social + linguistic parenting behavior in the graduate group and college group were significantly better than those in the high school/vocational group( F=3.965, P=0.012; LSD: P=0.020, P=0.002). Among mothers, the social parenting behavior ( F=2.812, P=0.040; LSD: P=0.008, P=0.023, P=0.009), linguistic parenting behavior ( F=3.769, P=0.011; LSD: P=0.010, P=0.025, P=0.001), social + linguistic parenting behavior ( F=3.654, P=0.013; LSD: P=0.005, P=0.015, P=0.002) in graduate and above groups were significantly better than those in college group, high school/vocational group, junior high school and below groups.The scores of social parenting behavior(40.72±6.80), linguistic parenting behavior(27.20±5.22), and social + linguistic parenting behavior(67.92±11.10) were significantly correlated with children’s fine motor(61.75±16.41)( r=0.193, P=0.001; r=0.153, P=0.009; r=0.190, P=0.001), cognition(68.28±16.83)( r=0.231, P=0.000; r=0.186, P=0.001; r=0.229, P=0.000), language(53.01±18.55) ( r=0.262, P=0.000; r=0.305, P=0.000; r=0.304, P=0.000) and social self-care(61.44±17.85) ( r=0.264, P=0.000; r=0.238, P=0.000; r=0.274, P=0.000). The scores of linguistic parenting behavior and social + linguistic parenting behavior were correlated with children's social life ability (8.65±0.89) ( r=0.142, P=0.046; r=0.140, P=0.049). There was no significant correlation between social parenting behavior, linguistic parenting behavior, social + linguistic parenting behavior and the scores of ABC scale (50.53±21.39) ( r=-0.089, P=0.336; r=-0.115, P=0.215; r=-0.107, P=0.250) and CABS scale (13.96±4.54) ( r=-0.050, P=0.490; r=-0.059, P=0.411; r=-0.058, P=0.421). Conclusions:The social and linguistic parenting behaviors are related to their age and educational level, and are significantly correlated to developing capability of children with autism, but have nothing to do with the severity of children's symptoms.

Changes of dopamine transporter function in striatum during acute morphine addiction and its abstinence in rhesus monkey / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Although dopamine transporter (DAT) is essential for addiction, the effect of additive drugs on DAT function is still controversial, especially for opiates. We investigated the functional changes of dopamine transporter in striatum of rhesus monkeys during acute morphine injection and its abstinence.</p><p><b>METHODS</b>Four rhesus monkeys, 6 to 9 years old, two male and two female, were examined for 12 days. Single photon emission computed tomography (SPECT) was performed with (99)T(cm)-TRODAT-1 as the radiopharmaceutical dopamine transporter agent during different stages of acute morphine injection and its abstinence. The ratios of SPECT signal between striatum and cerebellum (ST/CB) were calculated.</p><p><b>RESULTS</b>The ST/CB ratio declined significantly on the first day of morphine injection and continued declining with more morphine injections. After abstinence, the ratio increased with time, but was still significantly lower on the 5th day of abstinence than the normal level.</p><p><b>CONCLUSIONS</b>In rhesus monkey, acute morphine injection has both rapid and lasting effects on DAT by downregulating its function. The decline was partially reversible following morphine abstinence. The results suggest that striatum is one effective target of morphine and that the DAT function in striatum is one indicator for morphine addiction.</p>

Auditory evoked potentials recorded in monkeys with hallucinatory-like behaviors induced by bromocriptine / 神经科学通报·英文版

Objective Bromocriptine and other dopamine D2 receptor agonists can affect a range of behaviors in nonhuman primates, particularly those behaviors associated with motor and mental function, such as suppressant behaviors and hallucinatory-like behaviors in monkeys. Besides bromocriptine, the dysfunction of the rapid eye movement sleep (REM) mechanism may also contribute to hallucinations. Dissociation of wakefulness, REM, and non-REM (NREM) can cause a series of psychotic symptoms. Methods We simultaneously recorded auditory evoked potentials (AEP) from five cerebral regions in monkeys during normal and psychotomimetic states to investigate and compare state-dependent changes in AEP. Results Phase reversal of peak-to-baseline amplitude of 250 ms component (PBA250) in dorsolateral prefrontal cortex was common characteristic of hallucinatory-like and REM, and that hallucinatory-like and REM shared the equivalent modulatory orderliness of the PBA250 in dorsolateral prefrontal cortex. This result suggests that hallucinatory-like and REM share an equivalent electrophysiological modulatory in dorsolateral prefrontal cortex. Conclusion These results reveal that emergence of the N250 in dorsolateral prefrontal cortex is an exclusive marker that may help to discern whether hallucinatory-like behaviors is exhibited, which suggests that dorsolateral prefrontal cortex may be the most pivotal region for exhibition of hallucinatory-like behaviors.

Continuous representation of human portraits and natural scenery in human ventral temporal cortex: evidence from functional magnetic resonance imaging / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Functional magnetic resonance imaging (fMRI) has become a powerful tool for tracking human brain activity in vivo. This technique is mainly based on blood oxygenation level dependence (BOLD) contrast. In the present study, we employed this newly developed technique to characterize the neural representations of human portraits and natural sceneries in the human brain.</p><p><b>METHODS</b>Nine subjects were scanned with a 1.5 T magnetic resonance imaging (MRI) scanner using gradient-recalled echo and echo-planar imaging (GRE-EPI) pulse sequence while they were visually presented with 3 types of white-black photographs: natural scenery, human portraits, and scrambled nonsense pictures. Multiple linear regression was used to identify brain regions responding preferentially to each type of stimulus and common regions for both human portraits and natural scenery. The relative contributions of each type of stimulus to activation in these regions were examined using linear combinations of a general linear test.</p><p><b>RESULTS</b>Multiple linear regression analysis revealed two distinct but adjacent regions in both sides of the ventral temporal cortex. The medial region preferentially responded to natural scenery, whereas the lateral one preferentially responded to the human portraits. The general linear test further revealed a distribution gradient such that a change from portraits to scenes shifted areas of activation from lateral to medial.</p><p><b>CONCLUSIONS</b>The boundary between portrait-associated and scenery-associated areas is not as clear as previously demonstrated. The representations of portraits and scenes in ventral temporal cortex appear to be continuous and overlap.</p>

Specific neural basis of Chinese idioms processing:an event-related functional MRI study / 中华放射学杂志

Objective To address the neural basis of Chinese idioms processing with different kinds of stimuli using an event-related fMRI design.Methods Sixteen native Chinese speakers were asked to perform a semantic decision task during fMRI scanning.Three kinds of stimuli were used: Real idioms (Real-idiom condition);Literally plausible phrases (Pseudo-idiom condition,the last character of a real idiom was replaced by a character with similar meaning);Literally implausible strings (Non-idiom condition,the last character of a real idiom was replaced by a character with unrelated meaning).Reaction time and correct rate were recorded at the same time.Results The error rate was 2.6%,5.2% and 0.9% (F = 3.51,P0.05 )for real idioms,pseudo-idioms and wrong idioms, respectively.Similar neural network was activated in all of the three conditions.However,the right hippocampus was only activated in the real idiom condition,and significant activations were found in anterior portion of left inferior frontal gyrus (BA47)in real-and pseudo-idiom conditions,but not in non-idiom condition.Conclusion The right hippocampus plays a specific role in the particular wording of the Chinese idioms.And the left anterior inferior frontal gyms (BA47)may be engaged in the semantic processing of Chinese idioms.The results support the notion that there were specific neural bases for Chinese idioms processing.

Study on applied anatomy of carpal radial ligaments and the related Kinematics / 吉林大学学报(医学版)

Objective：To study anatomic basis of ligaments factors in carpal radial instability. Methods:The length, width, thickness and maximum length of radial scaphoid capitate ligament(RSCL) , radial lunate ligament(RLL) , radial scaphoid lunate ligament(RSLL),radial scaphoid ligament(RSL), scaphoid trapezium ligament(STmL), scaphoid lunate interosseous ligament(SLIL), scaphoid triangular ligament(STgL) and radial ulnar triangular ligament(RUTgL)were measured in the neutral position. The length of RSCL, RLL, RSLL, RSL and RUTgL in the maximum position of radial deviation, ulnardeviation, palmarflexes and dorsiflexes were also measured. The normal and maximal distance of scaphoid lunate gap(SLG) , scaphoid trapezium gap(STmG), radial scaphoid gap(RSG) and capitate lunate gap(CLG) were measured,especially for variation of SLG in the condition of different ligament lesions. Results:Volar carpal radial ligaments were thicker than dorsal ones. The injuries of SLIL, STmL, RSL and CLL were considered generally when SLG>4.78±0.54mm, STmG>3.71±0.32mm, RSG>5.77±0.79mm, CLG>4.62±79mm; when SLIL was incised completely, SLG>5mm. Keeping anatomic structure of SLIL and incising other ligaments, there existed no obvious variation in SLG. Keeping dorsal part and incising proximal and palmar ones, no obvious variation of SLG can be observed. Conclusions: There were no effects on SLG when carpal radial ligaments (except dorsal part of SLIL) were injuried .Dorsal part of SLIL played a very important role in keeping SLG normal.
