Hypoxia- inducible factor-1 ( HIF-1) promotes tumor deterioration, invasion and metasta-sis. Treatment targeting the HIF-1 signal pathway is becoming a hot research. In addition to uniquely selective inhibition of topoisomerase Ⅰ(Topo Ⅰ) ,the recent studies show that camptothecin compounds can regulate the activity of HIF-1 through decreasing HIF-1 protein translation and have been classified as a non-selective chemical inhibitor of HIF-1.

Sphingosine analogue FTY720 exerts good immune suppressive effect by inducing lymphocytes apoptosis and homing, which can be used for organ transplant rejection as well as anti-autoimmune disease treatment. Recent studies have found that FTY720 plays anti-tumor potential by inducing growth arrest and apoptosis as well as inhibiting tumor metastasis.

AIM:To establish a method for determining notoginsenoside R_1,ginsenoside Rg_1 and ginsenoside Rb_1 in Jingkang Capsules(Radix Rehmanniae praeparata,Radix Polygoni multiflori,Radix et Rhizoma Notoginseng,etc.). METHODS: A Diamonsil C_(18) column(250 mm?4.6 mm,5 ?m) with acetonitrile-water as the mobile phase was used for gradient elution,the flow rate was 1.0 mL/min and the UV detection wavelength was at 203 mn. RESULTS: There was a good linear relationship at a range of 0.327-2.180 ?g for notoginsenoside R_1(r=(0.999 4))(the average recovery was 98.23% with RSD of 1.53%(n=6)),0.909-6.060 ?g for ginsenoside Rg_1(r=1.0)(the average recovery was 99.04% with RSD of 1.00%(n=6)),0.672-4.480 ?g for ginsenoside Rb_1(r=0.999 8)(the average recovery was 98.17% with RSD of 1.31%(n=6)).CONCLUSION: The method is simple,quick and accurate.It can be used for the quality control of Jingkang Capsules.

OBJECTIVETo investigate the clinical therapeutic effects of anchors, peroneus brevis tendon augmentation and plantaris muscle tendon covering on the reconstruction of achilles tendon rupture caused by corticosteroids injection.

METHODSFrom March 2005 to April 2010, the clinical data of 10 patients with acute achilles tendon rupture repaired with suture anchors, peroneus brevis tendon augmentation and plantaris muscle tendon covering were retrospectively analyzed. The achilles tendon rupture was caused by corticosteroids injection. There were 8 males and 2 females with a mean age of (46.80 +/- 2.83) years old(ranged from 21 to 68 years). Postoperative complications, the range of movement of affected foot, number of consecutive heel raises and single leg jumpings were recorded. Functional recovery of achilles tendon were assessed according to ankle and hindfoot scores of the American Orthopedic Foot Ankle Society (AOFAS).

RESULTSAll patients were followed up for 12 to 18 months with an average of 13.5 months. No wound infection, re-rupture and rejection reaction were found. At the last follow-up, there was no significant difference in the range of movement between affected foot (54.5 +/- 6.3) degrees and unaffected foot (56.8 +/- 3.8) degrees (t = 0.989, P = 0.336). The affected foot could raise heel and do single-leg hops for 10 times continuosly. There was significant difference in AOFAS between preoperative score (67.3 +/- 7.6) and postoperative score (95.5 +/- 7.6) (t = 8.297, P = 0.000);and there was no significant difference between affected foot scores (95.5 +/- 7.6)and unaffected foot scores (98.5 +/- 6.3) (t = 0.961, P = 0.349). Function recovery of achilles tendon: 9 cases were good, 1 case was fine.

CONCLUSIONAnchors, peroneus brevis tendon augmentation and plantaris muscle tendon covering for the reconstruction of achilles tendon rupture caused by corticosteroids injection is a reliable and effective method, with advantage of simple operation, dependable fixation and less complications.

A dynamic electrocardiogram record system based on MSP430 SCM is developed in this paper. MSP430 SCM has ultra-low power consumption and a high integration level. The gathered ECG data are stored on a CF card. With low power consumption and being portable, the system is especially suitable for the occasion with the battery as power supply.

The physical change of astigmatism in human eye is analyzed in this article.Different methods for astigmatism applied in clinic are expound and compared with advantages and disadvantages.It is important that analyzing carefully and designing customized normgram for astigmatism eye to approach the perfect visual function after reasonable treatment.

Objective To determine the content of two original constituents of Liuwei Dihuang Wan migrating to blood. Methods HPLC- fingerprint of the preparation and drug- containing serum fingerprint were established by RP- HPLC. Based on the fingerprints, the original constituents migrating to blood were identified and determined by comparing with the standard. Results Loganin and paeonol were identified as the original constituents migrating to blood; the loganin content was 0.93? 0.01 mg/g and the paeonol was 0.37? 0.01 mg/g. Conclusion Using the constituent content migrating to blood as the parameter, this method will provide scientific evidence for improving the quality control of Liuwei Dihuang Wan. 

Purpose To investigate the comparison of miR-106a in fresh and paraffin-embedded tissues and its expression in precan-cerous 1esions of gastric cancer. Methods Human gastric cancer tissues inc1uding 30 coup1es of fresh and 40 coup1es of paraffin-em-bedded samp1es were co11ected,quantitative rea1-time PCR was used to detect the expression of miR-106a in these two samp1es. Anoth-er paraffin-embedded samp1es inc1uding 20 cases of precancerous 1esions and 40 cases of gastric adenocarcinoma were a1so co11ected,in situ hybridization was used to assess the expression of miR-106a in these stages. Results The re1ative expression of miR-106a in fresh tissues was 3. 25 ± 1. 99,in paraffin-embedded tissues was 3. 18 ± 2. 14,indicating that the expression of miR-106a in these two sam-p1es has no statistica1 difference(P>0. 05),corre1ation ana1ysis showed that there was a significant corre1ation of miR-106a expression in these two samp1es(rs =0. 998,P<0. 001). The expression of miR-106a was detected in the stage of precancerous 1esions with the positive rate was 70%. The positive signa1s were 1ocated in dysp1astic epithe1ia1 ce11s and appeared as dark b1ue fine granu1es. The positive rate of miR-106a in gastric cancer tissues was 87. 5% and the frequency and extent increased and enhanced compared with pre-cancerous 1esions. Conclusion miR-106a has significant corre1ation in gastric cancer fresh tissues and paraffin-embedded tissues. Detection of miR-106a with paraffin tissues and its ear1y changes in prema1ignant 1esions can provide va1uab1e information for the ear1y diagnosis of gastric cancer.
