ABSTRACT
ObjectiveTo investigate the comprehensive spoken communication performance of children with disabilities, and explore the related individual and environmental factors. MethodsFrom August to November, 2022, questionnaires of Communication Function Scale for Children based on ICF-CY were distributed online to parents of healthy children and children with disabilities aged two years to five years and eleven months in Shanghai, Nanjing and other areas. ResultsA total of 500 copies were sent out, and 407 valid questionnaires were returned, including 84 healthy children, 85 with hearing impairment, 119 with mental retardation, 35 with cerebral palsy and 84 with autism. There were significant differences in the comprehensive spoken communication function performance among the children with different impairment types (F = 127.618, P < 0.001). The comprehensive spoken communication ability was significantly poorer in the children with disabilities than in the healthy children (P < 0.05), and the ability was better in hearing-impaired children than in the children with other disabilities (P < 0.05). The higher the education of mother (r = -0.311, P < 0.001) and father (r = -0.280, P < 0.001), and family annual income (r = -0.228, P < 0.001), the better the children's comprehensive spoken communication performance; the children's comprehensive spoken communication performance was better when the family used Putonghua as unified communication language (r = 0.210, P < 0.001). ConclusionThe comprehensive spoken communication performance for children with disabilities is heterogeneous among different impairment types, and is affected by parents' education, family annual income, and family communication language.
ABSTRACT
@#Objective To investigate the risk factors of cognitive dysfunction in patients with traumatic brain injury. Methods From March to September, 2021, 556 hospitalized patients with traumatic brain injury were selected from a multicenter study. A 1∶1 sex-matched case-control study design was used. After assessment by Montreal Cognitive Assessment (MoCA), those with cognitive impairment were as case group and those without cognitive impairment were as control group. They were collected general data and assessed with Social Support Rating Scale (SSRS) and Hospital Anxiety and Depression Scale (HADS). Results Logistic regression analysis showed that college education or above (OR = 0.040) and high level of social support (OR = 0.118) were protective factors for cognitive impairment (P < 0.05). Aged 60 to 88 years (OR = 9.996), severe brain injury (OR = 7.345), headache after injury (OR = 2.159), frequent waking at night or multiple dreams ≥ three times per week (OR = 3.705), severe upper limb dysfunction caused by brain injury (OR = 6.072), depression (OR = 5.202) were risk factors for cognitive impairment (P < 0.05). Conclusion The related factors for cognitive impairment in patients with traumatic brain injury include general factors, disease factors, sleep, psychological and social support and other factors. It is suggested that in addition to the treatment of disease, it is necessary to improve sleep, psychology and social support, to reduce the incidence of cognitive impairment and promote the recovery of disease.
ABSTRACT
Objective To evaluate the significance of the mannose-binding lection (MBL) gene polymorphism at code 54 of exon 1 and MBL serum level and C-reactive protein (CRP) in the severity of community acquired pneumonia (CAP) in adults.Methods A prospective observation was conducted.104 adults Han patients with CAP hospitalized in Tianjin People's Hospital were enrolled.Frequencies of MBL54 alleles and genotypes were measured.The patients were evaluated by pneumonia severity index (PSI) score and were graded.Serum MBL was determined by enzyme linked immunosorbent assay (ELISA),and serum CRP was detected by immunoturbidimetry before and 4 days and 7 days after the treatment.100 healthy control subjects with the same region,age,gender,nationality were enrolled as control group.Serum MBL and CRP levels were compared between CAP group and the control group or among different grades of PSI,and the correlation was analyzed.Results The variation of GGC→GGC in MBL54 was found in CAP patients and controls.Similar frequencies of genotypes (x2=0.018,P=0.893) and alleles (x2=0.019,P=0.903) of MBL54 with wild type and mutant type were found between two groups.The serum MBL level (mg/L) before and 4 days and 7 days after the treatment in CAP group was increased followed by the reduction and they were 3.75 ± 1.78,4.53 ± 1.99 and 4.04 ± 1.91,respectivelv,which were significantly higher than those in control group (2.84 ± 1.41,all P＜0.01).The serum CRP levels (mg/L) in CAP group were gradually declined,and they were 66.88 ± 40.47,51.21 ± 37.54,36.91 ± 36.02,respectively,which were significantly higher than those in control group (6.96 ± 2.19,all P＜0.01).There were 12 cases with PSI grade Ⅰ,32 cases with grade Ⅱ,20 cases with grade Ⅲ,22 cases with grade Ⅳ and 18 cases with grade V in CAP patients.There was no significant difference in frequencies of MBL54 genotypes among different grades of PSI (x2=1.210,P=0.876) and between general ward and intensive care unit (x2=0.569,P=0.451).No differences in the serum MBL level before (F=1.313,P=0.279) and 4 days (F=1.705,P=0.165) and 7 days (F=1.684,P=0.170) after the treatment were found among different PSI grades.The serum MBL level 4 days after the treatment was significantly higher than that before treatment,then decreased to the level before treatment on the 7th day after treatment in CAP patients with grade Ⅱ-Ⅳ.There was significant difference in serum CRP level before (F=23.179,P=0.000) and 4 days (F=26.601,P=0.000) and 7 days (F=10.358,P=0.000) after the treatment among different PSI grades in CAP patients.The serum levels of CRP in patients with different PSI grades were gradually decreased with time prolonged,the higher the PSI grade,the more obscure the serum CRP decrease.No correlation was found between PSI grade and serum MBL before and 4 days and 7 days after the treatment (before treatment:r=-0.205,P=0.145; 4 days after treatment:r=-0.062,P=0.662; 7 days after treatment:r=-0.063,P=0.656),and positive correlation between PSI grade and serum CRP was found (before treatment:r=0.809,P=0.000; 4 days after treatment:r=0.842,P=0.000; 7 days after treatment:r=0.702,P=0.000).Conclusions The MBL54 codon genotypes had no effect on the susceptibility of CAP.The serum MBL was elevated and dynamic changes with increasing treatment time in CAP patients were shown.MBL can be used as a reaction of CAP in acute stage.But it cannot be used as an inflammatory marker for the severity of CAP.
ABSTRACT
<p><b>OBJECTIVE</b>To probe into the new idea along with establishment of a novel method for dynamic monitoring and early-warning on the wild resources of traditional Chinese medicines (TCMs).</p><p><b>METHOD</b>The alterations of wild traditional Chinese medicinal resources were assessed through the price ratio between drug and foodstuff (PRDF) indicating the balance between supply and demand of the specific TCMs, referred to the price ration between pork to foodstuff which is used in national monitoring to the balance between pork supply and demand.</p><p><b>RESULT</b>Since the price of rice was tightly controlled by government, it was selected as a relatively stable reference to build the PRDF in order to take away the non-marketing influence to TCMs price such as CPI and inflation rate. The modified relative alteration trend of TCMs price had been researched through comparing different formulae to build PRDF, including absolute average month price of TCMs, month average price ratio of TCMs to foodstuff (rice) , month-on-month change of TCMs to rice, year-on-year change of TCMs to rice, and difference in value of period-on-period change (DVPPC). In the research, Cordyceps, Glycyrrhiza and totally five herbs were selected as model drugs and the price data were collected from 2002 to 2008. The results showed that DVPPC calculated of relative long time window was more sensitive and stable to reflect the relative alteration trend of TCMs price. For instance, the DVPPC of Ligustici showed continuously increase trend in recent years. This suggested appearance of unbalance between supply and demand of Ligustici, and forced policy intervention to maintain reasonable and continuable utilization of Ligustici resource.</p><p><b>CONCLUSION</b>The proposed method and the formula of DVPPC revealed some useful guidance for dynamic monitoring the wild resources of TCMs.</p>

<p><b>OBJECTIVE</b>To probe into the influences of different granule sizes and to prepare procedures on rational clinical usage of rhubarb based on chemical equivalence.</p><p><b>METHOD</b>The effects of particle size, extract solvent, extract time and repeat times, and pre-extract or pro-extract of rhubarb on the extract amounts of the anthraquinones (AQs) were compared.</p><p><b>RESULT</b>The different prepare procedures investigated in the paper revealed significant influence on the extract amounts of the AQs and those extracts were not chemical equivalent. Ethanol extracted more AQs than water did, when other conditions were same. When extracted with water, the rhubarb of piece size 0.8-1.2 cm could extract relatively high amount of AQs nearly equal to superfine grinded powders, and the former was cheap. The water extraction of AQs showed an increasing trend with the extraction time extended. And pro-extract manner with water could extract more AQs than pre-extract manner with a extraction time of 30, 60 min. The water extraction of AQs repeated two times exceeded half of the amount of totally six times. When extracted with ethanol, the rhubarb of fine powders could extract relatively high amount of AQs nearly equal to superfine grinded powders. And pre-extract manner with ethanol could extract more AQs than pro-extract manner. The ethanol extraction of AQs increased in 30 min and then increased slower. The ethanol extraction of AQs repeated two times exceeded 70% of the amount of totally six times. So, the optimal conditions for water extraction rhubarb were pro-extract, two times repeated and 30 min per time; and the optimal conditions for ethanol extract were pre-extract, two times repeated and 30 min per time.</p><p><b>CONCLUSION</b>The different prepare procedures showed significant influence on the extraction of rhubarb AQs. There is great need to establish a good usage practice (GUP) for Chinese Materia Medica to maintain rational clinical usage.</p>

The differences of 34 rhubarb samples collected on the market and at producing area were investigated by chemical analysis on the contents of anthraquinones and chromatographic fingerprints, in order to assess the rationality of the commercial specification of rhubarb. The results indicated that the commercial specification of rhubarb was not correlated to the contents of anthraquinones as well as the price. The chromatographic fingerprints of rhubarb samples from different producing area were dissimilar, while the commercial specifications were difficult to be separated. Generally, the rhubarb samples produced in famous-region contained more anthraquinones. This demonstrated rationality on the traditional records of the famous-region of rhubarb from a chemical view. In this study, it was firstly reported that rhubarb could be categorized into two types, chrysophanol-type and rhein-type, based on the proportion of the two constituents in the total anthraquinones after acid hydrohysis. It was found that the rhubarb samples of rhein-type were mostly produced in famous-regions, such as Qinghai, Xizang, West Sichuan and Gansu. The literatures reported that rhein was superior to chrysophanol at many pharmacological effects and pharmacokinetic properties. Hence, we primarily considered that rhein-type rhubarb might be high-quality. These results were helpful to improve the commercial specification of rhubarb from a view of chemical information.

In this study the reliability and scientificity of organoleptic evaluation for the commercial specification of Chinese medicinal materials (CMM) was investigated with Delphi method, using rhubarb as an example. The consensus panel of panelists being expert in organoleptic evaluation for CMM was cogitatively selected, with high average authority index of 0.81. The average individual repeatability of selected panelists was 85%, while the group repeatability was above 70%. It was found that the career time of the expert had significant influence on the evaluation result (P < 0.05), which suggested that practice makes repeatability. Some panelists of different career type and education background concluded different results, but no statistical significance was found. Furthermore, four predominant organoleptic parameters, shape, color, texture and section characteristics, were selected based on statistics and panelists' discussion to judge the commercial specification of rhubarb. In conclusion, we firstly demonstrated the organoleptic evaluation is an objective and repeatable approach to judge the commercial specification of CMM; and we recommend Delphi method to do validation and standardization for the conventional experiences of traditional Chinese medicine.

Objective To establish an objective method for evaluating the intrinsic characteristics between cold and hot nature of Chinese materia medica(CMM)through the different effects of Mahuang decoction(MHD)and Maxing Shigan decoction(MSD)on animal temperature tropism.Methods The equipment with cold/hot pads was used to investigate the variety ofthe temperature tropism between two groups of mice treated by MHD and MSD,respectively.Meanwhile,the activities ofadenosine triphosphatase(ATPase),superoxide dismutase,succinate dehydrogenase,and malondialdehyde were measured.Results After treated by MHD,the macroscopic behavioral index of remaining rate on warm pad(40 ℃)of mice decreasedsignificantly(P < 0.05),suggesting the enhancement of cold tropism,meanwhile,the internal indices of ATPase activity and oxygen consuming volume increased significantly(P < 0.05),suggesting the enhancement of energy metabolism.On theother hand,the above-mentioned indices in MSD group changed on the inverse way.Conclusion The relative drug natureof MHD and MSD revealed in this study is consistent with the theoretical prognostication or definition.It indicates that theinternal cold and hot nature of CMM could be reflected in ethological way on the changes of animal temperature tropismwhich might be internally regulated by body energy metabolism.
ABSTRACT
Through our pre-investigation and literature analysis, it was found that rhubarb could be categorized into two types, chrysophanol-type and rhein-type, based on the proportion of the two constituents in the total content of anthraquinones after acid hydrolysis. In this paper, the antimicrobial activities of chrysophanol-type and rhein-type rhubarbs against Staphylococcus aureus were compared with microcalorimetric analysis, in order to illustrate the bioactive differentiability between the two chemotypes. For the aim to display the distinction of chrysophanol and rhein percentage in total anthraquinones, the sampling volume was regulated to make the total anthraquinones equivalent, thus, the antimicrobial difference was only attributed to the difference of chemotypes. The results indicated that the antimicrobial difference between the two chemotypes was confirmable labeled at the biothermokinetic parameters of S. aureus growth affected by the rhubarb samples. The growth rate constant (k1) of the first exponential phase for the growth of S. aureus affected by the rhein-type rhubarb was significantly lower than that of chrysophanol-type (P<0.01), which suggested stronger antimicrobial activity of rhein-type rhubarb than that of chrysophanol-type. However, the antimicrobial activities of rhein-type rhubarbs were not positively correlated to the contents of rhein. It suggested that the antimicrobial activity of rhubarb might be related to some unknown components which were of same accumulating pattern of rhein. The findings in present study provided some experimental evidence on categorizing rhubarb into two chemotypes through the difference of antimicrobial activity on S. aureus by microcalorimetric analysis and, further, offered references to revision of the commercial specification of rhubarb from chemical view.
