The fibrous roots are the residues of production of cut crude drug of Danshen (Salvia miltiorrhiza). Enzymatic pretreatment and ultrasonic extraction are beneficial to extract effective constituents from fibrous roots more effectively. The present research was to optimize the enzymatic parameters by the central composite design and response surface method. Under the best conditions, the yields of total tanshinones and total salvianolic acids in the extracts of enzymatic pretreatment increased by 113.92% and 30.64%, comparing with the non-enzymatic extraction, respectively. TLC analysis also showed that the types of effective constituents in the two samples were not affected by enzymatic hydrolysis. Meanwhile, the complex correlation coefficients of the mathematical models were high, which provided a good prediction.

OBJECTIVETo optimize a pretreatment method of urine proteomics in children with primary nephrotic syndrome.
METHODSUrine from children with primary nephrotic syndrome was treated in different pH and isolated by cold acetone precipitation for different durations. Then the amounts and kinds of proteins were compared by quantify, SDS-polyacrylamide gel electrophoresis (SDS-PAGE) and two-dimensional electrophoresis (2-DE) in order to optimize a way to deal with urine protein.
RESULTSMost proteins were obtained at pH 2.7. The amounts of protein precipitated by acetone for 0.5 hr was obviously less than those precipitated for 1 and 2 hrs (P<0.05), while there was no significant difference between the amount of protein precipitated for 1 and for 2 hrs. Protein precipitated by cold acetone for 1 hr at pH 2.7 was selected as the best pretreatment method. Satisfactory 2-DE maps can be acquired.
CONCLUSIONSUrine protein can be best obtained at pH 2.7 and precipitated by cold acetone for 1 hr.

Objective To observe the clinical efficacy of Tiao Shen Jie Jing needling (regulating the mind and release spasm) in treating post-stroke upper-limb spastic palsy. Method Ninety patients with post-stroke upper-limb spastic palsy were randomized into an observation group and a control group, 45 cases each. The observation group was intervened by Tiao Shen Jie Jing needling, while the control group was given ordinary acupuncture. The Modified Ashworth Scale (MAS), short-form Fugl-Meyer Assessment (SFMA) and Barthel Index (BI) were evaluated and recorded prior to the treatment, after 2-week and 4-week treatment and 3 months later after the intervention; the serumγ-aminobutyric acid (GABA) was detected before and after the treatment. Result The total effective rate was 83.3% in the observation group versus 61.0% in the control group, and the efficacy of the observation group was superior to that of the control group (P<0.05). The scores of each scale showed improvements after the treatment in both groups (P<0.05), and the improvements in the observation group were more significant (P < 0.05). The follow-up showed continuing improvements in the scales in the observation group, which were superior to those in the control group (P<0.05); after the treatment, the content of GABA in the observation group was significantly higher than that in the control group (P<0.05). Conclusion Tiao Shen Jie Jing needling can effectively ameliorate the upper-limb spasm,as well as the motor function of the upper extremities, improve the activities of daily living and maintain a long-term efficacy, better than ordinary acupuncture. The action mechanism is related to the regulation of GABA content in serum.

Objective To evaluate the efficacy and safety of oxiracetam in the treatment of neurological deficits resulting from brain injury through the comparison of oxiracetam for injection and piracetam for injection in clinical trials. Methods A multiple-center, randomized, double-blind,parallel study was performed on 239 patients; these patients were divided into experimental group (oxiracetam for injection, n=120) and control group (piracetam, n=119). National institutes of health stroke scale (NIHSS), Glasgow coma scale (GCS), myodynamia grading, mini-metal state examination (MMSE) were employed to evaluate the therapeutic effects; electrocardiogram and laboratory examination were performed, and the side effects were also observed. Results The scores of NIHSS,GCS and myodynamia grading after treatment in the 2 groups were all significantly higher than those before treatment (P<0.05); however, no significant differences on these scores were noted between the experimental group and control group (P>0.05). No serious adverse events were noted in both groups.Conclusion Oxiracetam, the same as piracetam, is safe and effective in the treatment of neurological deficits secondary to brain injury.

OBJECTIVETo investigate the clinicopathological characteristics, diagnosis, treatment and prognostic factors of gastric gastrointestinal stromal tumors(GIST) in the stomach.
METHODSThe clinicopathological data of 132 patients with gastric GIST between January 1998 and December 2008 were analyzed retrospectively, and the prognostic factors were evaluated.
RESULTSTumor locations were the cardia or fundus (50, 37.9%), the stomach body (62, 47%),the antrum (13, 9.8%), and two regions were found in 6 cases (4.5%), three regions in 1 cases (0.8%). Tumor size ranged from 1.0 to 27.0 cm with an average of 9.4 cm. All the patients underwent complete tumor resection, including multi-organ resection in 41 cases. Thirty-four cases underwent lymph node dissection. All the lymph nodes were negative. The positive rate was 93.2% (23/132) for CD 117 and 82.6% (109/132) for CD34. The 1-,3- and 5-year survival rates of the 118 cases with follow up were 94.7%, 80.2%, and 56.6%, respectively. Univariate analysis revealed that the differences in Fletcher classification, tumor size, infiltration to surrounding tissue, preoperative metastasis, and adjuvant postoperative therapy with imatinib were related to the survival rates. Multivariate analysis demonstrated that Fletcher classification, preoperative metastasis and adjuvant postoperative therapy with imatinib were independent poor prognostic factors for survival.
CONCLUSIONSPreoperative metastasis is an independent factor predicting poor prognosis of gastric GIST. Fletcher classification can be used to evaluate the biological behaviors and prognosis, while surgery is the main therapy and targeted therapy can improve survival of gastric GIST.
