OBJECTIVE:To establish the method to control the quality of Qilian suppository.METHODS:TLC was per?formed to identify Rhizoma coptidis and Radix Notoginseng.A reverse phase HPLC-ELSD method was adopted to determine the content of ginsenoside Rg 1 and ginsenoside Rb 1 in Radix Notoginseng.RESULTS:The study on the quality control showed that the characteristic of identification by TLC was distinct and highly specific.In this quantification method,the linear ranges of ginsenoside Rg 1 and Rb 1 were1.56?g～3.74?g(r=0.9993,RSD=1.6%)and1.44?g～3.46?g(r=0.9981,RSD=1.2%)respectively.The average recovery rate of ginsenoside Rg 1 was99.10%,and RSD=1.6%(n=3);the average recovery rate of ginsenoside Rb 1 was102.13%,and RSD=1.2%(n=3).CONCLUSION:The method is simple,sensitive,accurate and re?peatable.It can be used for the quality control of Qilian suppository.

Objective:To investigate the clinical features, imaging features, treatment options and prognosis of linear scleroderma with central nervous system involvement.Methods:One case of linear scleroderma " en coup de sabre" (LSES) school-age child suffering from dizziness, vomiting and blurred vision was admitted to the Department of Pediatrics, Peking University First Hospital on March 25, 2019.The curative effect was observed after treatment.The relevant literature was searched, and the characteristics of cases and therapeutic effects were reviewed.Results:The clinical features of this case included recurrent and transient dizziness, vomiting, and blurred vision.Cranial imaging indicated abnormal signals in the left frontotemporal lobe white matter, cingulate gyrus, basal ganglia region, and corpus callosum proximal pressure part, multiple soft meningeal line enhancement and abnormal brain substance enhancement on the brain surface in the lesion area.After 2 months of combined treatment with Methotrexate(MTX) and corticosteroids, some symptoms such as dizziness and vomiting disappeared.Three months after the treatment, in the primary cerebral hemisphere and multiple calcifications in the brain parenchyma, the lesions significantly reduced in cranial imaging.The child was followed up for 11 months and displayed no clinical symptoms.New hair was dense at the alopecia area, and skin color, texture and grain were close to normal at the damaged area.In the review of domestic literature, treatment and prognosis were not involved.Foreign literatures reported 5 cases of children, with the first choice of Methylprednisolone being combined with MTX treatment, significant effect was observed, and consistent with the treatment of this case.Conclusions:In order to detect and treat them as early as possible and improve the prognosis, LSES patients should undergo cranial integrity assessment and neurological imaging examination at an early stage, regardless of clinical manifestations of nervous system involvement.

Objective To observe the effects of a rehabilitation robot and body weight supported treadmill training (BWSTT) on the walking ability of hemiplegic patients after stroke.Methods Sixty hemiplegic patients were divided randomly into treatment and control groups (n=30 in each).The treatment group received training assisted by a leg rehabilitation robot for 10-20 min once daily,6 days per week for 8 weeks in addition to conventional treatments and BWSTT.The control group was only given conventional treatments and BWSTT once daily for 8 weeks.Their lower extremity functions,balance and walking ability were assessed with a simplified Fugl-Meyer assessment (FMA) and using the Berg balance scale (BBS) and Functional Ambulation Categories (FACs).Results After training,both groups showed significant improvements in terms of FMA,BBS and FAC results.The treatment group showed significantly better improvements in lower extremity function,balance and walking ability compared with the control group.Conclusions The lower-limb rehabilitation robot and BWSTT could together improve balance and walking ability.

Objective To discuss the technical points, safety and clinical effectiveness of DSA-guided percutaneous acetabuloplasty (PA) for the treatment of acetabular metastases. Methods Fifteen patients, including 6 males and 9 females, with acetabular malignant metastases were enrolled in this study.A total of 19 lesions were detected. The lesions were 13 - 25 mm in size (mean 19 ± 4 mm), the dose of PMMA used for per lesion was 5 - 13 ml (mean 8.2 ± 2.3 ml). All patients complained of greater or less degree of pain in their hips, 8 patients had to use walking stick, 4 patients showed limping although they could walk independently and three patients could not walk alone. DSA-guided percutaneous acetabuloplasty was performed in all patients and follow-up after the procedure was conducted for 1 - 12 months. Visual analogue score (VAS), walking state score and analgesic dosage taken by the patients were used for the evaluation of the clinical effectiveness. The complications were analyzed. All the data obtained were statistically analyzed with paired samples t test and analysis of variance by using SPSS12.0 statistical software.Results The procedure was technically successful in all patients. Pain rating evaluated by the VAS decreased from a mean of 7.8 before surgery to a mean of 4.2 in 24 hours after surgery (P < 0.01 ), which further decreased to 2.5 in one month (P < 0.01 ), while walking state score increased from a mean of 1.5before surgery to a mean of 2.5 in 24 hours after surgery (P < 0.01 ). The analgesic dosage taken by the patient was reduced in 14 patients and remained the same in one patient. The bone cement leakage into paraacetabular soft tissues occurred in three cases and peripheral vascular exudation of acetabulum was observed in three cases with no obvious clinical symptoms. Conclusion As a safe, reliable and minimally-invasive technique, DSA-guided percutaneous acetabuloplasty has excellent anti-pain effect in treating acetabular metastases. This therapy can markedlyimprove the patient's walking ability and the quality of life.

Objective To explore the neuroimmunomedulation mechanism of ICAM-1 and LFA-1 in children with febrile seizures (FS).Methods 40 children with FS were dividedinto simple FS(SFs)groupin20 cases and complex FS(CFS)groupin20 cases,and 30 health children matched with regard to age and sex were enrolled into control group.The real-time fluorescence quantitative PCR wag used to detect the expression of PBMC ICAM-1 mRNA.At the same time,the PBMC LFA-1 mRNA expression wfs studied with Send-QuantitativeRT-PCR analysis.Results The levels of PBMC ICAM-1 mRNA in SFS group were significantly higher than those in control group and CF$group(P<0.05).The levels ofPBMC ICAM-1 mRNA showed downtrend between CFS group and control group.but there was no statistical difference between the two groups(P>0.05).The levels of PBMC LFA-1 mRNA grey-scales in SFS group were significantly higher than those in control group and CFS group(P<0.05).In addition,the levels of PBMC LFA-1 mRNA in CFS group showed downtrend than those in control group,but there wti8 no statistical difference between the two groups(P>0.05).Conclusions The gene expression levels of PBMC ICAM-I/LFA-I in SFS group were different from those in CFS group.Inflammable immunopathology damage induced by ICAM-1/LFA-1 may play an important role in the pathogenesis of SFS.On the contrary,ICAM-1/LFA-1 may have seme neuroprotective effects on the pathogenesis of CFS.

Objective To investigate the expression of miR?126, miR?355 and exportin?5 in lung cancer. Methods The cancer tissue and the tissue adjacent to carcinoma of 47 cases of patients with lung cancer was used to detect the expression of miR?126, miR?355 and Exportin?5 by the real?time fluorescence quantitative PCR. Results Significant difference of the expression of miR?126 (t=2.02,P=0.03) and exportin?5 (t=4.62,P<0.01) was observed in lung cancer tissue and tissue adjacent to carcinoma. Mature miR?126 and pri?miR?126 (R=0.309 , P = 0.044) had a negative correlation in the tissue adjacent to carcinoma. In the cancer tissue,miR?126 and MRP (R=0.432, P=0.019), miR?335 and k167 (R=0.410, P=0.033) were positively correlated, however, exportin?5 and TOPO (R=0.357, P=0.045), the pri?miR?126 and drinking (R=0.340, P=0.024), the pri?miR?126 and MRP (R=0.427, P=0.027) had a negative correlation relationship. Conclusion Expression of miR?126 and exportin?5 was decreased in lung cancer tissue, which may contribute to the occurrence and development of lung cancer.

Objective Using the third high sensitive cardiac troponin I assay to establish the reference intervals of serum cardiac marker high sensitivity cardiac troponin I ( hs-cTnI ) in apparently healthy subjects of Beijing area, and to explore the relationship between cTnI and other parameters.Methods Using random selection method, a total of 440 serum samples were collected from apparently healthy subjects of Beijing area.Among them, 217 cases were male, average age was (50.0 ±14.3) years old;223 cases were female, average age was ( 49.0 ±14.0 ) years old.All of these serum samples were detected hs-cTnI using i2000 Abott biochemical analyzer and ARCHITECT STAT Abbott assay kit.And the 99th percentile upper reference limit was used as the reference interval.Non-parametric tests were used to compare the different groups, the U Mann-Whitney test was used between two groups, the Kruskal-Wallis test was used in many groups, and the correlation analysis was used Spearman method.Results The 99th percentiles of hs-cTnI in 440 apparently healthy subjects is 9.66 ng/L.While the male group is 9.66 ng/L, and the female group is 8.25 ng/L.The serum hs-cTnI level of male is higher than female ( 9.95 ng/L vs 8.25 ng/L, P<0.05 ).According to the spearman correlation analysis, the serum hs-cTnI level appears positive correlation with age, brain natriuretic peptide (BNP), alanine aminotransferase (ALT),aspartate transaminase ( AST) ,gamma-glutamyl transferase ( GGT) ,total bilirubin ( TBIL) ,serum creatinine ( SCR) , hemoglobin (HGB)(P<0.05,R>0),and appears negative correlation with platelet (PLT)(P<0.05,R<0).Conclusion The serum hs-cTnI level apparently differents with gender, so it is necessary to establish reference intervals among different gender group of Beijing area.

Objective To test the reliability and validity of the Chinese version of the John Hopkins Adapted Cognitive Exam ( ACE) in NICU patients. Methods The English ACE was translated and adapted into the Chinese version . Cognitive functions of 40 critically ill patients in NICU were assessed with the Chi?nese version of ACE and MMSE battery.The scores of ACE and MMSE were analyzed to test the content va?lidity,construct validity,concurrent validity,internal consistency,inter?rater reliability and test?retest reliabil?ity.Result The correlation coefficient between each factor and the total score ranged from 0.617 to 0.938, and the content validity was good.The ACE was significantly correlated with MMSE( r=0.822, P<0.05). Five factors were extracted by main principle analysis, the cumulative contribution was 85. 90%, the factor loading of each item was all over 0.5,the scale had good construct validity.There existed a good internal con?sistency ( Cronbach’ α=0.756 ) as well as a good inter?rater reliability ( ICC>0.95) and test?retest reliabil?ity (ICC=0.652?0.979) of the Chinese version of ACE.Conclusions The Chinese version of ACE has been proved to be a reliable and valid screening tool for cognitive impairment in NICU patients.

In order to identify Aucklandiae Radix, Vladimiriae Radix, Inulae Radix, Aristolochiae Radix and Kadsurae Radix using ITS2 barcodes, genomic DNA from sixty samples was extracted and the ITS2 (internal transcribed spacer) regions were amplified and sequenced. The genetic distances were computed using MEGA 5.0 in accordance with the kimura 2-parameter (K2P) model and the neighbor-joining (NJ) phylogenetic tree was constructed. The results indicated that for Aucklandiae Radix (Aucklandia lappa), Vladimiriae Radix (Vladimiria souliei and V. souliei var. cinerea), Inulae Radix (Inula helenium), Aristolochiae Radix (Aristolochia debilis) and Kadsurae Radix (Kadsura longipedunculata), the intra-specific variation was smaller than inter-specific one. There are 162 variable sites among 272 bp after alignment of all ITS2 sequence haplotypes. For each species, the intra-specific genetic distances were also smaller than inter-specific one. Furthermore, the NJ tree strongly supported that Aucklandiae Radix, Vladimiriae Radix, Inulae Radix, Aristolochiae Radix and Kadsurae Radix can be differentiated. At the same time, V. souliei (Dolomiaea souliei) and V. souliei var. cinerea( D. souliei var. cinerea) belonging to Vladimiriae Radix were clearly identified. In conclusion, ITS2 barcode could be used to identify Aucklandiae Radix, Vladimiriae Radix, Inulae Radix, Aristolochiae Radix and Kadsurae Radix. Our study may provide a scientific foundation for clinical safe use of the traditional Chinese medicines.

Objective To investigate the clinical efficacy of Loewenstein Occupational Therapy Cognitive Assessment (LOTCA) battery for patients at the early stage of traumatic brain injury (TBI). Methods 72 patients with TBI hospitalized from January, 2013 to October, 2014 and 30 healthy controls matched gender, age and educational background were assessed with the Chinese version of LOTCA battery and Mini-Mental State Examination (MMSE) respectively. Results The score of MMSE and LOTCA were correlated (r=0.56, P<0.01). Compared with the controls, the scores of all the subtests of LOTCA decreased (P<0.01) in the patients, especially the orientation, visuomo-tor organization and thinking operation;with the more incidence of medium and serious dysfunction of all the subtests of LOTCA except perception (P<0.01), in which thinking operation was the most and attention was the least. The area under the receiver operating curve (ROC) was (0.84±0.04) in LOTCA, less than that of (0.91±0.03) in MMSE (P<0.05). Conclusion Cognition is widely impaired in patients after TBI, most involved thinking operation. LOTCA is less effective to identify cognitive dysfunction than MMSE, and can be used as an al-ternation or a supplement.
