The CO I gene sequences of Qianghuoyu, Pachytriton labiatus and Gehyra mutilata were achieved by PCR amplification and bi-directional sequencing. Furthermore, a pair of specific primers SJYW1 and SJYW2 in the non-conservative district were designed through sequence alignment. The PCR reaction condition was established by changing the annealing temperature and cycle numbers. The results showed that 350 bp DNA fragment was amplified from Qianghuoyu in PCR with annealed temperature at 54 °C and the cycle number was 25 cycles, whereas not any DNA fragment was amplified from P. labiatus and G. mutilata under the same reaction condition. This method is well-performed in the identification of Qianghuoyu for its excellent specificity and repeatability.

Objective To study the effect of intensive trunk muscle training on balance and walking in pa- tients with hemiplegia caused by stroke.Methods A total of 90 stroke patients were recruited and randomly divid- ed into a treatment group(45 cases)and a control group(45 cases).All the patients were given conventional reha- bilitation training.Meanwhile,intensive trunk muscle training was also administered for those in the treatment group as well.The trunk control function,balance ability and walking ability were assessed by using the trunk control test, Berg Balance Scale and the balance subscale of the Fugl-Meyer physical performance test,and Holden's functional ambulation classification,respectively,before and after 6 weeks of training.Results It was found that all the pa- tients scored better with the trunk control test,Berg's balance scale,the balance subscale of the Fugl-Meyer physical performance test and Holden's ambulation classification after treatment,and there were significant differences between the two groups after treatment(P

Objective To explore the effect of action observation therapy (AOT) on upper limb function in children with spastic hemiplegic cerebral palsy,and the better program. Methods From March to November,2017,45 children with spastic hemiplegic cerebral palsy were randomly assigned to control group and AOT group.The control group was further divided into group A(n=11)and group B(n=11), and received conventional rehabilitation treatment and scenic-observation therapy, 20 minutes every time for group A,and 30 minutes every time for group B.AOT group was further divided into group C(n=10)and group D (n=11), and received AOT in addition, 20 minutes every time for group C, and 30 minutes every time for group D,five times each week for twelve weeks for all the groups.Before treatment,eight and twelve weeks af-ter treatment, they were assessed with hand grip strength, Upper Extremities Functions Test (UEFT), and Wee Functional Independence Measure(WeeFIM). Results After treatment,the hand grip strength and the score of UEFT were better in group D than in groups B and C(P<0.05),and were better at twelve weeks than at eight weeks(P<0.05).No significant difference was found in the score of WeeFIM among groups after treatment(P>0.05). Conclusion AOT could improve upper limp function in children with spastic hemiplegic cerebral palsy,and it's more ef-fective after more training.

To study the chemical constituents from the root of Berchemia lineata (L.) DC., nine compounds were isolated from the EtOAc extract by using silica gel, RP-C18 silica gel column chromatography and preparative HPLC. Based on the spectroscopic analysis, their structures were identified as 5-hydroxy-7-(2'-hydroxypropyl)-2-methyl-chromone (1), (-)-(1'R, 2'S)-erythro-5-hydroxy-7-(1', 2'-dihydroxypropyl)-2-methyl-chromone (2), naringenin (3), eriodictyol (4), (+)-aromadendrin (5), (+)-taxifolin (6), (+)-catechin (7), (+)-epigallocatechin (8) and quercetin (9). Among them, compound 2 is a new chromone derivative. Compound 1 is a known chromone derivative and isolated from this genus for the first time. Compounds 3-9 are known flavonoids and isolated from this plant for the first time.

To study the chemical constituents of aerial parts of Laggera pterodonta (DC.) Benth., the air-dried aerial parts of this plant were powered and extracted with boiling water and purified by silica gel column chromatography and recrystallized. Eleven compounds were obtained from L. pterodonta. They were identified as to be 6-O-beta-D-glucopyranosyl-carvotanacetone (1), pterodontic acid (2), 1beta-hydroxy pterondontic acid (3), pterodontoside A (4), pterodondiol (5), pterodontriol B (6), 5-hydroxy-3,4', 6,7-tetramethoxyflavone (7), artemitin (8), chrysosplenetin B (9), quercetin (10) and beta-sitosterol (11). Compound 1 is a new monoterpene glucoside. Compounds 10 and 11 were isolated from this plant for the first time. Compounds 2 and 5 showed moderate activity against bacteria including Staphylococcus aureus, Pseudomonas aeruginosa, Bacillus subtilis, Mycobacteium phlei and Bacillus circulans by paper disc diffusion method, while they both displayed no activity against Escherichia coli.

OBJECTIVEPrimary airway neoplasms are extremely rare in the pediatric age group. This paper reports 4 children with primary airway neoplasms to explore the clinical manifestations, safety and efficacy of bronchoscopic interventions.

METHODThe data of pathology, photographic documentation and imaging studies were analyzed.

RESULTOf the 4 reported lesions, 2 were characterized by low-grade (2 with mucoepidermoid carcinoma) and 2 by high grade malignant (spindle cell carcinoma and malignant lymphoma). Onset of clinical manifestations occurred at the ages of 7 months to 7 years. All of them were initially misdiagnosed as bronchitis, asthma or atelectasis. The lesions located in trachea in 2 patients, in left bronchus of 1 patient and in right middle bronchus of 1 case. Atelectases occurred in bilateral bronchus where the lesions obstructed almost the entire lumen at the time of diagnosis. The diagnosis of airway masses depends upon maintaining a high index of suspicion, complemented by imaging and timely diagnostic endoscopy. The lesions were completely removed in 3/4 patients except 1 died during bronchoscopic procedures.

CONCLUSIONThe children with malignant airway neoplasms were presented with cough and wheezing without specific manifestations. Bronchoscopic interventions were effective in the treatment of non-operative cases. General anesthesia is strongly recommended for interventional bronchoscopy.

To study the chemical constituents of the Entada phaseoloides (L.) Merr., seeds of Entada phaseoloides were extracted with 70% ethanol at room temperature. Isolation and purification were performed by silica gel, reversed-phase silica gel column chromatography and semi-preparative HPLC. Structures of the pure compounds were established on the basis of spectral analysis. Four sulfur-containing amide compounds were isolated from the n-BuOH-soluble fraction and identified as entadamide A-beta-D-glucopyranosyl-(1-->3)-beta-D-glucopyranoside (1), entadamide A (2), entadamide A-beta-D-glucopyranoside (3) and clinacoside C (4). Compound 1 is a new compound. Compound 4 is isolated from the genus Entada for the first time.

Objective To investigate the incidence and bacterial etiology of stent associated respiratory tract infec-tion (SARTI) caused by two types of airway stents.Methods Silicone and coated metal airway stent were placed into patients with central airway stenosis caused by varied pathologies. The incidence of stent related respiratory tract infection,bacteria etiology of SARTI and improved dyspnea score were compared between two groups receiving different airway stent.Results 1)Totally 171 patients received airway stents, and among them, 39 patients (22.81%) developed SARTI.2)The incidence of SARTI in metal stent group and silicone stent group was 29.21% (26/89) vs.15.85% (13/82),P<0.05;3)Bacterial spectrum of SARTI was different in metal and silicone stent groups:staphylococcus aureus was 38.46% vs. 69.23%,respectively;candida albicans was 23.08% vs. 0%,re-spectively;Singular proteus was 7.26% vs.0%,respectively;4)The narrowed lumen was improved from 74.27%± 7.13% to 17.64%±6.22%in the metal stent group,while the data was improved from 74.94%±9.18% to 12.68%± 8.32% in the silicone stent group (P<0.01). Accordingly, the dyspnea symptomscore was improvedfrom 2.85 ± 0.89 to 0.85±0.68 in metal stent group,and from 2.88±0.91 to 0±0.61 in the silicone stent group (P<0.05). Conclusions Compared with metal airway stents,silicone stents have a lower incidence of SARTI,which mightbe due to the projections in the silicon stent surface and wider expanded in the bronchial stenosis.
