Objective To investigate the effect of elispheric motion on balance and walking ability of hemiplegic patients after stroke. Methods From September to December, 2016, 40 hemiplegic patients after stroke were randomly divided into control group (n=20) and ob-servation group (n=20). Both groups received conventional rehabilitation, additionally, the control group received juggling ball training, and the observation group received elispheric motion combined with juggling ball training, 20 minutes a day, six days a week for six weeks. They were assessed with the Fugl-Meyer Assessment-Sensory (FMA-S), Fugl-Meyer Assessment-Lower Extremity (FMA-LE), Berg Bal-ance Scale (BBS) and TimedUp and GoTest (TUGT) before and six weeks after training. Results After training, the scores of FMA-S, FMA-LE, BBS significantly increased (t>10.012, P<0.05) in both groups, and were higher in the observation group than in the control group (t>2.129, P<0.05);the time of TUGT significantly shortened (t>10.001, P<0.001) in both groups, and were shorter in the observation group than in the control group (t>4.669, P<0.05). Conclusion Elispheric motion can facilitate to improve the balance and walking ability of hemi-plegic patients after stroke.

Superoxide dismutase(SOD) was purified from Tegillarca granosa and the effects of tributyltin chloride(TBTCl) on the enzyme activity of the SOD were analyzed at different conditios. The results showed that the effects of TBTCl on SOD activity were more ohvious at room temperature than at four degrees centigrade. 58. 1 % of the enzyme activity was reserved after SOD was incubated with 200?g?mL-1 of TBTC1 for 72 hours at room temperature, while 90. 9% of the enzyme activity was reserved at four degrees centigrade. The enzyme activity of SOD was reduced with the increase of TBTC1 concentration and interaction time. TBTCl could reduce heat-resisting, acid-resisting and alkali-resisting abilities of SOD. With TBTCl concentration increase,SOD isozyme bands in the graph of polyacrylamide gel electrophoresis were getting weaker.

Objective To identify the factors related to radiation pneumonia (PR) in lung cancer treated with intensity modulated radiotherapy (IMRT).Methods Data from 163 lung cancer patients treated with IMRT were analyzed with clinical factors and physical parameters related to the dose-volume histogram.The patients were followed for 6 months after radiotherapy.The relationship between survival status and PR was analyzed.Results The incidence rate of over grade 2 patients was 28.22 ％ (46/163).Univariate analysis revealed a significant relationship between many parameters associated with such as the site of lobe (P =0.033),COPD (P =0.020),chemotherapy (P =0.020) and prophylactic using of glucocorticoid and antibiotic (P =0.025).Multilogistic regression analysis showed that V20 in the contralateral site,the V5 of the all lungs and PTVV were independent factors.Conclusion The RP is associated with multiple factors.Individualized treatment plans should be made according to the specific circumstances of patients.

Objective To investigate the effect of different doses of ketamine on inflammatory cytokines in rabbits with severe burn at early stage and preliminarily approach its regulatory action on early stage of inflammatory reaction due to stress of trauma.Methods Forty healthy male New Zealand rabbits were randomly divided into four groups in accord with the random number table method: normal control group, scald model group, ketamine analgesia group and ketamine anesthesia group. Before scald, pentobarbital sodium was used for anesthesia, afterwards catheters were inserted into internal jugular vein and internal carotid artery respectively ready for use, and 24 hours later, Ⅲ degree scald at the animal back and buttocks occupying 30% total body surface area (TBSA) was performed as the scald model for all the rabbits except those in normal control group. In ketamine analgesia group, after scald for 0.5 hour, 0.5 mg/kg ketamine intravenous injection was given to the rabbits as the loading dosage and then persistent intravenous pump infusion of 9μg·kg-1·min-1 ketamine was applied for all together 24 hours. In ketamine anesthesia group, after scald for 0.5 hour, 1.5 mg/kg ketamine intravenous injection was given to the rabbits, and then persistent intravenous pump infusion of 45μg·kg-1·min-1 ketamine was applied for 4 hours to maintain systemic anesthesia. In normal control and scald model groups, only intravenous infusion of equal amount of normal saline was given to the rabbits. The amount of intravenous transfusion in each group and the total dosages of ketamine used in ketamine analgesia group and ketamine anesthesia group were recorded. Before scald and 0.5, 6, 12, 24 hours after scald, arterial blood gas analyses were made, and the levels of serum interleukins (IL-1, IL-6) and tumor necrosis factor-α (TNF-α) were determined.Results Although the indexes of blood gas analysis were changed in the four groups, they were all in the normal range, showing that the respiratory function was in the normal range and indirectly reflecting that the circulatory function was also in the normal range, thus the effects on cytokines by factors of respiratory and circulatory functions were ruled out. The levels of IL-1, IL-6 and TNF-α before scald showed no statistically significant differencesamong the four groups (allP > 0.05). From 0.5 hour after scald, the levels of IL-1, IL-6 and TNF-α were markedly higher in model group than those of normal control group [IL-1 (ng/L): 30.27±0.93 vs. 13.79±1.11, IL-6 (ng/L): 47.22±1.49 vs. 46.31±4.12, TNF-α (ng/L): 243.39±20.85 vs. 190.95±14.97, allP < 0.05], and the situation continued until 24 hours after scald; the levels of IL-1, IL-6 and TNF-α from 6 hours after scald were significantly decreased in ketamine analgesia and ketamine anesthesia groups compared with those in the model group, and from 12 hours after scald, the degrees of descent in levels of the above indexes in ketamine analgesia group were more obvious than those in ketamine anesthesia group [IL-1 (ng/L): 19.28±2.51 vs. 40.12±10.31, IL-6 (ng/L): 52.10±4.23 vs. 72.20±10.11, TNF-α (ng/L): 246.03±20.74 vs. 313.71±27.34, allP < 0.05].Conclusion The low-dose ketamine analgesia and ketamine anesthesia have certain degree of inhibitory effect on the expression and release of inflammatory cytokines at the early stage in rabbits with severe burn, the effect of long-term low-dose ketamine analgesia being more significant.

There is a variety of gut microbiota in human body, which is closely associated with the health and disease. Normal gut microbiota can produce colonization resistance to pathogens. Antibiotics can affect the composition of gut microbiota and change the intestinal microenvironment, resulting in intestinal microecological disorders, which in turn cause intestinal pathogenic infections and other diseases. In this paper, the concept of intestinal microecology, the mechanism of intestinal colonization resistance, the effect of antibiotics on intestinal microecology, and the treatment methods were reviewed, aiming to provide the information for the rational use of antibiotics and the development of more effective treatment methods to maintain the stability of intestinal microecology.

To study the pharmacokinetics characteristic of loganin, ferulic acid and stilbene glucoside in rat plasma after oral administration of Bushen Tongluo formula. The plasma samples were treated by using liquid-liquid extraction technique, the concentrations were determined by HPLC-UV. Johnson spherigel C18 column (4.6 mm x 250 mm, 5 μm) was adopted and eluted with the of mobile phase of methanol-water containing 0.01% glacial acetic acid in a gradient mode, with the flow rate at 1.0 mL x min(-1), column temperature at 30 degrees C and injection volume of 10 μL. According to the findings, loganin was determined at 235 nm, ferulic acid and stilbene glucoside were determined at 320 nm, with the sample size of 10 μL. The pharmacokinetic parameters of loganin, ferulic acid and stilbene glucoside were calculated by DAS 2. 0 software as follows: C(max) was (0.369 ± 0.042), (0.387 ± 0.071), (0.233 ± 0.044) mg x L(-1); t(max) was (0.226 ± 0.022), (0.282 ± 0.031), (0.233 ± 0.044) h; t(½β) was (6.89 ± 0.20), (10.73 ± 0.11), (6.93 ± 0.09) h; AUC(0-∞) was (1.91 ± 0.36), (3.22 ± 0.52), (1.52 ± 0.33) mg x h x L(-1); AUCO(0-t) was (1.62 ± 0.33), (2.58 ± 0.43), (1.30 ± 0.30) mg x h x L(-1); CL was (20.2 ± 4.0), (1.39 ± 0.23), (31.7 ± 6.9) L x h(-1) x kg(-1), respectively. The results showed that after the oral administration with Bushen Tongluo formula, loganin, ferulic acid and stilbene glucoside showed concentration-time curves in conformity with the two compartment model, with a rapid absorption, loganin and stilbene glucoside was excreted at a moderate speed, and ferulic acid was excreted slowly (but with the highest bioavailability). Bushen Tongluo formula can main maintain plasma concentration with three administrations everyday and so is suitable to be made into common oral preparation.

Objective To determine whether prenatal ultrasonography (US) score is more effective than renal pelvic anterior posterior diameter (PAPD) for the prognostic evaluation of fetal hydronephrosis.Methods Fetuses with hydronephrosis (PAPD≥ 10 mm) were examined by prenatal US in the third trimester.PAPD,renal parenchyma thickness (RPT) and pelvicaliceal morphology (PM) were measured and graded from 0 to 3 score on the basis of severity of hydronephrosis,then the total US score of each kidney was obtained.According to the follow-up results after birth,all the cases were divided into two groups:physiological and pathological hydronephrosis.Via Z test,paired comparison was made to analyze area under the curve (AUC) of US score and each of the other three factors.Results Confirmed by postnatal US and other clinical examinations,of 198 kidneys (158 cases ) with hydronephrosis,139 (70.20％ ) were physiological hydronephrosis and 59 (29.80％ ) were pathological hydronephrosis.AUC of PAPD,RPT,PM,US score was 0.897 (minimum),0.957,0.944 and 0.982 (maximum) respectively,and there was significant difference between AUC of US score and each of the other three ( P ＜0.05).US score was the best approach for differential diagnosis of fetal hydronephrosis.Conclusions Prenatal US score is more effective and accurate than the single factor (PAPD,RPT,PM) to differentiate fetal physiological and pathological hydronephrosis.It was a new quantitative method to evaluate the prognosis of fetal hydronephrosis,and should be disseminated and applied clinically.

Fifty-eight samples belonging to 7 species of Arisaematis Rhizoma and its adulterants were collected. The ITS2 locus was employed as a DNA barcode and amplified, sequenced and assembled for all of the collected samples. Then, ITS2 sequences have been annotated using HMM-based method. The intra- and inter-specific variations were calculated and NJ tree was constructed using MEGA 6.0 software. The results showed that inter-specific K2P distances were significantly larger than intra-specific distances for all of the three origin species of Arisaematis Rhizoma. Furthermore, three origin species, Arisaema amurense, A. erubescens and A. heterophyllum, can be respectively formed to be a single branch with high bootstrap values. It is concluded that ITS2 can be used to correctly identify Arisaematis Rhizoma from its adulterants and the application of ITS2 in the identification of traditional Chinese medicine has an important prospective.
