ObjectiveTo investigate the role of electroencephalogram (EEG) examination in the prognosis evaluation of patients with severe craniocerebral injury.MethodsFifty-seven patients with severe craniocerebral injury were selected as study subjects and their clinical data were analyzed retrospectively.All the patients got EEG examination,and the relationships between EEG grading and Glasgow coma scale (GCS) score,the prognosis of outcome were analyzed.ResultsThe EEG of 57 patients within 24 h after hospitalization were all abnormal.There was significantly negative correlation between EEG grading and GCS score (r =-0.742,P ＜0.05).EEG grading was significantly positively correlated with the prognosis of outcome (r =0.730,P＜ 0.05).ConclusionsEEG examination and EEG grading can evaluate the prognosis of patients with severe craniocerebral injury.It provides reference for clinical treatments.

Objective To observe the expression of Toll-like receptors (TLRs) 2,4 and 9 in lesions of lupus vulgaris and tuberculosis verrucosa cutis,and to evaluate the possible roles of these receptors in the pathogenesis of cutaneous tuberculosis.Methods Skin specimens were obtained from the lesions of 18 patients with clinically and pathologically diagnosed lupus vulgaris or tuberculosis verrucosa cutis,15 patients with plaque-type psoriasis (positive control),and from perilesional normal skin of 10 patients with pigmented nevi (negative control).Immunohistochemistry was used to detect the expression of TLRs 2,4 and 9 in these specimens,and the expression intensity was expressed as absorbence values.Data were analysed by using the SPSS 13.0 software,and t test was conducted to assess the differences between the three groups of specimens.Results TLR-2 was observed mainly in the middle and upper layer of epidermis in lesions of cutaneous tuberculosis and psoriasis,and in the whole epidermis except the basal layer in normal skin,with no significant difference in the expression intensity between the three groups of specimens (0.25 ± 0.04 vs.0.25 ± 0.05 vs.0.28 ± 0.03,P ＞ 0.05).TLR-4 was weakly expressed in cutaneous tuberculosis lesions,absent or slightly expressed in normal skin and psoriatic lesions,and the expression level of TLR-4 was significantly higher in cutaneous tuberculosis lesions than in normal skin and psoriatic lesions (0.16 ± 0.07 vs.0.07 ± 0.09 and 0.02± 0.05,t =2.58,6.24,P ＜ 0.01 and 0.05).TLR-9 was expressed in the whole epidermal layer,including appendages and vascular walls,of cutaneous tuberculosis and normal skin,with a significant increase in cutaneous tuberculosis than in the normal skin (0.25 ± 0.05 vs.0.19 ± 0.05,t =2.88,P＜ 0.05).Conclusions TLRs 2,4 and 9 are all expressed in cutaneous tuberculosis losious,and the expression intensity of TLR-4 and TLR-9 is higher in cutaneous tuberculosis lesions than in normal skin,hinting that TLR-4 and TLR-9 play a certain role in the immune response of cutaneous tuberculosis.

Objective To observe the expressions of antimicrobial peptides LL-37,human beta defensin2 (HBD-2) and HBD-3 in the lesions of lupus vulgaris and tuberculosis verrucosa cutis,and to speculate the pathogenesis of cutaneous tuberculosis.Methods Tissue specimens were collected from the lesions of 18 patients with lupus vulgaris or tuberculosis verrucosa cutis and 15 patients with psoriasis,as well as from the normal skin of 10 healthy controls.The specimens were embedded by paraffin and subjected to an immunohistochemical analysis for the detection of antimicrobial peptides LL-37,HBD-2 and HBD-3.Statistical analysis was performed by using the SPSS 13.0 software package,and t test was carried out to compare the expressions of LL-37,HBD-2 and HBD-3 between these groups.Results LL-37 and HBD-2 were observed mainly in the upper and middle layer of the epidermis,appendages and vascular endothelial cells in cutaneous tuberculosis lesions.The expression levels of LL-37 and HBD-2 were significantly higher in tuberculosis lesions than in the normal skin (t =2.632,2.399,both P ＜ 0.05).Psoriatic and tuberculosis lesions shared a similar expression pattern for LL-37 and HBD-2.HBD-3 was absent in the lesions of cutaneous tuberculosis,but present in both psoriatic lesions and normal skin.Conclusions Both LL-37 and HBD-2 may participate in the immune response in cutaneous tuberculosis,while the absence of HBD-3 may contribute to the pathogenesis of cutaneous tuberculosis.

Intestinal flora is an important component of the body and is closely related to the health of infants and toddlers.There are many hypotheses about the origin and establishment mechanism of intestinal flora, but most theories are still controversial.The intestinal flora is not static, and its biodiversity and abundance will continue to differentiate and evolve with the growth and development of nurslings.It is now believed that intestinal flora plays a variety of roles in maintaining the homeostasis of the infant's internal environment.This review summarizes the basic research on the physiology of infantile intestinal flora in recent years, to provide some reference for the development of this branch in the field of pediatrics.

OBJECTIVE： To establish a UHPLC method for determination of the contents of 11-keto-β-boswellic acid(KAB) and 11-keto-β-acetyl-boswellic acid(AKBA)in Frankincense and explore the suitability and accuracy of substitute reference substance method with DRS origin software for qualitative and quantitative determination of chromatographic peaks. METHODS ：The samples were separated by UHPLC for determination of AKBA and KBA. AKBA was used as a reference to investigate the accuracy of KBA identification using DRS origin software on 19 different C18 columns. The RSDs of relative correction factors were calculated for different detection wavelengths and instruments.The relative correction factor method and the external standard method were selected for quantification and the differences were compared. RESULTS: The established method met the requirements of methodology and the average recovery was 100.21%(n=6) with RSD of 2.47%. The DRS origin software can be used to accurately determine the chromatographic peaks. The correct factor of AKBA vs. KBA was 0.936 and it was consistent under different conditions. There were no significant differences between the content calculated by the relative correction factor method and by the external standard method. CONCLUSION： This method is intelligent, feasible, reliable and economical, and can be used for the determination of frankincense content.

OBJECTIVE:To prepare Luhuifangba burn cream and establish a method for its quality control.METHODS:The burn cream was prepared from freeze-dried powder of aloe barbadensis miller gel,borneol,hexadecanol,cosmolin,sodium dodecylsulfate,glycerol,ethylparaben and distilled water.Polysaccharide in the preparation was identified by paper chromatography,and borneol was identified by means of the color reaction between1%vanillin-sulfuric acid and bornyl alcohol and isoborneol.The content of polysaccharide in the cream was determined using anthrone-sulfuric acid method.RESULTS:The preparation was a cream in ivory white color,which spread easily and smelled slightly oily.Polysaccharide and borneol in aloe were able to be identified by the above-mentioned method.The linear range of polysaccharide was0.02～0.2mg/ml,and the average recovery was106.3%(RSD=2.5%).CONCLUSION:The preparation method is feasible,and the quality control method is simple,accurate,and reproducible.

BACKGROUND:Exogenous basic fibroblast growth factor (bFGF) plays an important role in the ligament tissue healing process, and the use of transgenic methods to transfect exogenous genes into cells can promote the secretion of bFGF. OBJECTIVE:To observe phenotypic changes and the bFGF protein expression after bFGF recombinant adenovirus was used to transfect rabbit bone marrow mesenchymal stem cells (BMSCs). METHODS:Passage 2 BMSCs were divided into three groups:Ad.bFGF-eGFP group, Ad.eGFP group and control group. Under a phase contrast microscope we observed the changes in cellmorphology. The expression of bFGF protein in BMSCs was determined by enzyme-linked immunosorbent assay (ELISA). The proliferative curve was detected by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT). RESULTS AND CONCLUSION:The transfected cells showed a uniform phenotype of fibroblasts. MTT colorimetric assay revealed that more proliferative activity of transfected BMSCs was shown in the Ad.bFGF-eGFP group than in the Ad.eGFP group and control group. ELISA results showed that expression of bFGF protein was higher in the Ad.bFGF-eGFP group than in the Ad.eGFP group and control group (P<0.05). BFGF recombinant adenovirus can induce the differentiation of BMSCs into fibroblasts, increase proliferative ability and promote the expression of bFGF protein.

Objective To observe the clinical curative effect of Gubenzhike granule on cough variant asthma (CVA), and explore its mechanism. Methods A total of 140 cases of CVA were randomly divided into two groups, 70 cases for each group. The treatment group took Gubenzhike granule orally, and the control group inhaled Budesonide Powder for Inhalation and Salbutamol Sulphate Aerosol, respectively for 8 weeks, with 8 weeks follow-up after treatment. The same nursing intervention was implemented in two groups. Cough symptom scores of the two groups were observed after treatment and at the end of follow-up, the number of eosnophils (EOS) and content of immunoglobulin E (IgE) in peripheral blood were also observed. Results The treatment group completed 67 cases and the control group completed 66 cases. After treatment, the cough symptom scores, EOS and IgE in two groups were significantly reduced (P<0.01, P<0.05), and the cough symptom score of treatment group decreased more significantly than that of control group (P<0.01). The total effective rate and recurrence rate were 91.04%and 9.84%in treatment group, and 83.33% and 30.91% in control group. The total effective rate of treatment group was better than the control group (P<0.01), and the recurrence rate was lower than the control group (P<0.01). Conclusion Gubenzhike granule showed significant effect and low recurrence rate on CVA. Good anti-inflammatory and antianaphylaxis effects may be one of its mechanisms.

Objective:To study the variation of recent bladder function of the patients who received radical hysterectomy and evaluate its significance. Methods:Sixty-three patients with cervical carcinoma in International Federation of Gynecology and Obstetrics(FIGO) stage IB1 to ⅡA received urodynamic examination before and after operation. The urodynamic parameters included filling cystometry, pressure-flow rate, and electromyography of sphinctienter. Results:Radical hysterectomy induced significant increase in the first sensation (P<0.01)and post voiding residual of bladder (P<0.01) ;whereas caused significant decrease in the maximum volume(P<0.01), compliance(P<0.01),maximum flow rate(P<0.01) and the pressure at the maximum flow rate(P<0.01), respectively, compared with the corresponding values before the operation. Short-term bladder dysfunctions were observed in 34 patients (54.0%) including bladder detrusor dysfunction, low compliance bladder, bladder outlet obstruction, dyssynergia of urethral external sphincter and detrusor overactivity. The incidences of low compliance bladder and bladder detrusor dysfunction increased significantly after operation (P<0.01). Urinary retention was found in 28.6%(18/63) patients. The incidences of bladder detrusor dysfunction (66.7% vs 20.0%) and detrusor overactivity (33.3% vs 4.4%) in the group with urinary retention were significantly higher than those of corresponding group without urinary retention. Conclusion:The bladder function had obvious short-term changes following radical hysterectomy. In the many types of bladder dysfunction the main dysfunctions were low compliance bladder and bladder detrusor dysfunction. The bladder detrusor dysfunction might be the major cause of the urinary retention following the surgery. Urodynamic test was important for post-operative analysis and treatment of bladder dysfunction.

Objective To evaluate the effect of the expression of P-glycoprotein (P-gp) in the tumor tissue on the analgesic efficacy of fentanyl and lornoxicam in patients with cancer pain. Methods One hundred advanced cancer patients with pain aged 49-64 yr weighing $$-65 kg were included in this study. The expression of Pgp was positive in the tumor tissue in 50 patients (groups F1 and L1, n = 25 each) and negative in 50 patients (groups F2 and L2, n = 25 each). The patients in 4 groups received 48 h of pstient-controlled intravenous analgesia (PCIA). A loading dose of fentanyl 0.05 mg was administered before PCIA was started in groups F1 and F2 .The PCIA solution contained fentanyl 1 mg and droperidol 5 mg in 100 ml of normal saline in groups Ft and F2, or lomoxicam 64 mg and droperidol 5 mg in 100 ml of normal saline in groups L1 and L2. The PCA pump was set to deliver a background infusion of 2 ml/h and a bolus dose of 0.5 ml at 15 min lockout interval. Pain was assessed with VAS scores (0 = no pain, 10 = worst pain), and VAS score was maintained at ≤3 during PCIA. Flurbiprofen 50 mg was injected intravenously when VAS score≥4 and the consumption of flurbiprofen was recorded. The consumption of fentanyl and lornoxicam during PCIA was recorded. Blood samples from the internal jugular vein were taken at the beginning of PCIA (T0), and at 4, 12, 24, 48 h of PCIA (T1-4) for determination of blood fentanyl and lornoxicam concentrations. Results Flurbiprofen was not used in groups F2, L1 and L2. The consumption of flurbiprofen was ( 184 ± 41 ) mg in group F1 . There was no significant difference in the consumption of fentanyl during PCIA between groups F1 and F2 ( P ＞ 0.05). Blood fentanyl concentrations were not detected at all the time points in groups F1 and F2 . The VAS score during PCIA ≤ 3 in groups L1 and L2, and there was no significant difference in blood concentrations of lornoxicam at each time point and the consumption of lornoxicam during PCIA between groups L1 and L2 ( P ＞ 0.05). Conclusion Positive P-gp expression in the tunor tissue can decrease the analgesic efficacy of fentanyl, but exerts no effect on the analgesic efficacy of lornoxicam in patients with cancer pain.
