Objective To seek a useful index for assessing the change of human gait function based on the application of wavelet entropy in the gait data analysis.Methods The ground reaction force(GRF)gait data of 2 groups(10 young and 10 elderly subjects)were acquired with Bertec 3 dimensional force measured system(a strain gauge force platform)during normal walking.The orthogonal discrete wavelet transform was used for decomposing the collected gait data.The relative wavelet energy and wavelet entropy were defined and calculated respectively.They were statistically analyzed with t-test technique respectively to evaluate the change of human gait function.Results There was significant difference between the relative wavelet energy from GRF gait data of the two subject groups.The average values of wavelet entropy from the GRF gait data of elderly subject group were obviously less than those from the GRF gait data of young subject group.With the value of significance level of t-test P

Objective To study the intestinal absorption kinetics of Tripterygium wilfordii (TW) solid dispersions and the effects of different intestinal segments, drug concentrations, pH value, and P-glycoprotein (P-gp) on intestinal absorption. Methods The absorption behavior was investigated in situ with a single-pass intestinal perfusion (SPIP) model in rats. The content of each index component was determined by HPLC. The gravimetric method was used to correct the data and calculate the absorption rate constant (Ka) and apparent permeability coefficient (Papp) of each index component. Results The index components of TW were absorbed in the whole intestine, and the absorption rate constant (Ka) of all the index components of TW solid dispersion was significantly increased than that of extract (P < 0.05), and had some differences among different segments. With the increase of drug concentration, the absorption of each index component had saturation phenomenon, which indicated that it may be carrier-mediated transport mechanism. Acidic environment (pH 5.4) was beneficial to the absorption of various index components, especially the acidic content celastrol. After adding P-gp inhibitor, the Ka and Papp of celastrol were significantly different from those without P-gp inhibitor (P < 0.05), which suggested that it may be the P-gp substrate. Conclusion All the index components of TW solid dispersion are absorbed in the whole intestine and have saturation phenomenon, which suggested the absorption may be carrier-mediated transport mechanism. Acidic environment is beneficial to the absorption of all components. The absorption process of celastrol is affected by drug concentration and P-gp inhibitor, which indicated that it may be P-gp substrate. The preparation of solid dispersing can significantly enhance the absorption of various components of TW, suggesting that all the index components are BCS II drugs, and the bioavailability of the preparation may be improved.

Objective To explore the clinical significance of serum HGF level changes in gastric cancer pa-tients. Methods 60 cases of patients who operatied and clinicopathological confirmed gastric cancer, were detected serum HGF level by enzyme linked immunosorbent assay(ELISA) .40 cases were administered radical gastrectomy,20 cases of patients who had distant metastasis and loss operative chance were detected 7 days and 3 months preopera-tive,postoperative serum HGF level respectively. At the same time 40 cases of chronic gastritis patients and 40 cases of healthy examination people were selected as control group. Results Serum HGF level in patients with gastric canc-er was significantly higher than that of chronic gastritis and normal controls(P <0. 01). The serum HGF level of pa-tients with tumor vascular invasion significantly increased(P <0. 05). The patients with lymph node metastasis,serum HGF level was significantly higher than that patients with no lymph node metastasis(P <0. 05). The serum HGF level of patients with liver metastasis was significantly higher than that patients with no liver metastasis(P <0. 05). The se-rum HGF level of gastric cancer patients whose maximum diameter of the tumor ≥3cm were significantly higher than that maximum diameter of the tumor <3cm(P<0. 05). According to TNM staging of gastric cancer,the serum HGF level of Ⅰ phase and Ⅱ phase patients were significantly lower than that Ⅲ phase and Ⅳ phase patients(P <0.05).The serum HGF level of gastric cancer patients had no significant correlation with sex ,age and histological type(P <0.05). The serum HGF level of 40 cases of patients who were 1 week after surgery were significantly decreased,the patients who were 3 months after surgery were more obvious(P <0. 05 and P <0. 001). Conclusion HGF may play an important role in gastric cancer occurrence and development. The detection of serum HGF level can become an im-portant index for monitoring the degree of gastric cancer and prognosis of patients.

Objective: To objectively evaluate the short-term and long-term efficacies of arthrolysis under brachial plexus anesthesia in treating adhesive capsulitis of the shoulder (ACS). Methods: One hundred patients diagnosed with ACS were divided into two groups using the random number method. The two groups both received same active rehabilitation exercises. Besides, 55 cases in the treatment group were given one session of arthrolysis under brachial plexus anesthesia, and 45 cases in the control group were given tuina treatment. Changes in the visual analog scale (VAS) score, Melle score and pressure pain index were observed 1 month and 3 months after treatment. The therapeutic efficacies were also compared. Results: The total effective rate was 96.4％ at the 1-month follow-up and 96.4％ at the 3-month follow-up in the treatment group. The total effective rate was 33.3％ at the 1-month follow-up and 28.9％ at the 3-month follow-up in the control group. There were significant differences between the two groups comparing the total effective rate at the two time points (both P<0.05). The scores of VAS, Melle and pressure pain were significantly different at the 1-month and 3-month follow-ups from those before treatment in the treatment group (all P<0.05); the three scores did not show significant differences at the 1-month and 3-month follow-ups compared with those before treatment in the control group (all P>0.05). Conclusion: Based on the active rehabilitation exercises, one session of arthrolysis under brachial plexus anesthesia can release the adhesion and restore the range of motion and function of shoulder joint in ACS patients. It is superior to rehabilitation exercises plus tuina treatment comparing both short-term and long-term efficacies.

Objective Pathogen and antimicrobial susceptibility in children with bacterial meningitis were reviewed.Methods The positive cultures of cerebrospinal fluid samples or blood samples and its antimicrobial susceptibility were analyzed in 401 patients with the clinical diagnosis of bacterial meningitis.Results 401 cases cerebrospinal fluid samples and blood samples submitted to microbiology laboratory, 97 cases (24%) were microscopically and culturally proven to be bacterial meningitis. The most frequent pathogen was staphylococcus aureus (28%), followed by the streptococcus pneumoniae (19%) and escherichia coli (13%). Pediococci as conditioned pathogen, were found in purulent meningitis patients. One of the isolates of Staphylococcus aureus was simultaneously resistant to both vancomycin and teicoplanin. Three isolates showed simultaneous resistance to imipenem/cilastatin.Conclusions Staphylococcus aureus as the predominant pathogens of pediatric ranks first among pediatric patients of purulent meningitis. Serious drug resistance of isolated pathogenic bacteria and its in antimicrobial susceptibility in the bacterial meningitis should be considered in clinical therapy.

Objective To estimate the effects of different surgical treatments of giant cell tumor of bone(GCTB) of long bone in children.Methods The effects of surgical treatment of 15 cases suffered from GCTB were observed.The tumors were rated according to the system of Enneking classification,stageⅠwas managed with a curettage combined with local adjuvant treatment and filled by allograft bone or with curettage and filled by cement of bone.StageⅡb was treated by en bloc resection followed by reconstruction with large segment bone of allograft.The follow-up was given in all patients.Results The follow-up period was 7 years(ranged 2-16 years).In all 15 children patients with GCTB,there were 13 children in stageⅠ,9 patients with curettage combined with local adjuvant treatment and allograft bone showed good bone knitting and rehabilitation without deformity and functional problem and locally recurred;4 patients with curettage and filled by cement of bone showed 2 cases locally recurred.Two children in stageⅡb treated by en bloc resection followed by reconstruction with large segment bone of allograft were perfectly incorporated without evidence of obvious immune rejection,collapse,fracture and locally recurred,but the limb-suffered was short about 2 cm.Conclusions Stage Ⅰtreated by a curettage combined with local adjuvant treatment and filled by allograft bone can get good effect,but only treated by a curettage and filled by cement of bone has 50% locally recurred.TheⅡb treated by en bloc resection followed by reconstruction with large segment bone of allograft might influence the limb growth,but without locally recurred.

Objective To explore the therapeutic effects of combined application of survivin antisense nucleic acid and taxol in subcutaneous xenograft mouse model of Balb/c and to preliminarily investigate the mechanism of the anticancer effects.Methods The model of subcutaneous tumor was established by hypodermic injection of C26 cells into Bal b/c mice.The mice were then randomly divided into five groups through the internal tumor injection:the blank group (C),lipo2000 group (L),paclitaxel group (T),survivin antisense nucleic acid group (A),and survivin antisense nucleic acid combined with paclitaxel group (A+T).We observed tumor growth,determined cell apoptosis by TUNEL method,and detected the expression of survivin by Western blot.Results ① All treatment groups had T/C<60%,which was significantly different from that of group L (P <0.05);the intervention was proved effective in vivo .The tumor inhibition rate of mice tumor weight showed that there were significantly curative effects in groups T,A and A+ T compared with that in group C (P < 0.05 ).The antitumor activity of paclitaxel (tumor inhibition rate of 21.82%±0.84%)could be improved by more than 59% through combination therapy (tumor inhibition rate of 54.1 6% ± 0.32%)concerning inhibition of tumor weight growth.② TUNEL method detected apoptotic cells:The tumor cells hardly had apoptosis in the blank group while T group and A group had a certain number of apoptotic cells.The experiment results suggested that PTX could promote tumor cell apoptosis,and that not only A+T strengthened the effect in killing tumor cells,but also the synergy of both could influence tumor resistance and ultimately make the effect in promoting tumor cell apoptosis conspicuous.③ The expression of survivin protein:The results showed that the expression of survivin protein in group A + T was obviously decreased without the expression of β-actin affected;it did not change significantly in group C compared with group L.The ratio of the A-value in groups T,A and A+T was 0.895 ±0.01 1,0.704 ±0.121 and 0.345 ± 0.01 9,respectively.Analysis of variance t-test showed that the expression level in group A+T obviously differed from that in groups C,L,A and T (P <0.05).Conclusion The combined therapy of survivin antisense nucleic acid and taxol can promote tumor cell apoptosis by downregulating the expression of survivin protein,reduce the body’s resistance to drugs and create synergetic effects.
