The content of gamma-aminobutyric acid in the aerial part of Panax notoginseng in different productive area was determined by using high performance liquid chromatography. HPLC analysis was made on a C18 (4.6 mm x 250 mm,5 microm) with acetonitrile and water containing 4.1 g x L(-1) sodium acetate as mobile phase. The detection wavelength was 254 nm. The HPLC method showed good linearity within the range of 0.01 - 1.03 g x L(-1). The average recovery of GABA in the stems and leaves of P. notoginseng and the flowers of P. notoginseng was 101.7% (RSD 1.1%, n = 3) and 97.3% (RSD 0.38%, n = 3), respectively. The contents of GABA in the samples of different productive areas were not significant different, and the average contents of GABA in the stems and leaves of P. notoginseng and the flowers of P. notoginseng were 0.49% and 0.53%. This method was simple and reliable, and it was suitable for the determination of gamma-aminobutyric acid in the aerial part of P. notoginseng.

The stromal interaction molecule (STIM)?calcium release?activated calcium channel protein (ORAI) and inositol 1,4,5?trisphosphate receptors (IP3Rs) play pivotal roles in the modulation of Ca2+?regulated pathways from gene transcription to cell apoptosis by driving calcium?dependent signaling processes. Increasing evidence has implicated the dysregulation of STIM–ORAI and IP3Rs in tumorigenesis and tumor progression. By controlling the activities, struc?ture, and/or expression levels of these Ca2+?transporting proteins, malignant cancer cells can hijack them to drive essential biological functions for tumor development. However, the molecular mechanisms underlying the participa?tion of STIM–ORAI and IP3Rs in the biological behavior of cancer remain elusive. In this review, we summarize recent advances regarding STIM–ORAI and IP3Rs and discuss how they promote cell proliferation, apoptosis evasion, and cell migration through temporal and spatial rearrangements in certain types of malignant cells. An understanding of the essential roles of STIM–ORAI and IP3Rs may provide new pharmacologic targets that achieve a better therapeutic effect by inhibiting their actions in key intracellular signaling pathways.

OBJECTIVETo evaluate the clinical efficacy and safety of Huayu Tongbi Recipe (HTR) combined methotrexate (MTX) in treating refractory rheumatoid arthritis (RRA).
METHODSTotally 167 RRA patients were assigned to the treatment group (73 cases) and the control group (94 cases) according to different therapeutic methods. Patients in the treatment group were treated with HTR combined MTX, while those in the control group were treated with leflunomide (LEF) combined MTX. Clinical signs and symptoms, RF, CRP, ESR, disease activity score 28 (DAS28), and safety indicators were compared between the two groups before treatment, at week 12 and 24 after treatment. The efficacy and safety indices were also evaluated.
RESULTSAt week 12 after treatment the total effective rate was 82.2% (60/73 cases) in the treatment group and 79.8% (75/94 cases) in the control group, showing no statistical difference between the two groups (chi2 = 0.15, P > 0.05). At week 24 after treatment the total effective rate was 78.1% (57/73 cases) in the treatment group and 755% (71/94 cases) in the control group, showing no statistical difference between the two groups (chi2 = 0.15, P > 0.05). There was statistical difference in the total effective rate between week 24 and week 12 in the control group (chi2 = 0.49, P < 0.05). Clinical signs and symptoms, RF, CRP, ESR, and DAS28 were significantly improved in the two groups after 12- and 24-week treatment (P < 0.01). There was no statistical difference in the improvement at week 12 after treatment between the two groups (P > 0.05). There was statistical difference in time of morning stiffness, tender joint numbers, swollen joint numbers, patient global assessment, RF, CRP, and DAS28 at week 24 after treatment between the two groups (P < 0.05). Besides, adverse reactions occurred less in the treatment group than in the control group (P < 0.01).
CONCLUSIONThe efficacy of HTR combined MTX was equivalent to that of LEF (10 mg per day) combined MTX, but with more stable therapeutic effects and less adverse reactions.

OBJECTIVETo evaluate clinical efficacy of suture anchors in treating acute injuries of medial collateral ligament (MCL) of knee at degree III.
METHODSTwenty-seven patients with degree III acute MCL injuries of knee were treated with suture anchors from January 2007 to June 2011. There were 15 males and 12 females, aged from 19 to 56 (averaged 32.6) years old. The time from injury to operation was 3 to 10 days, averaged 6 days. Symptoms and physical signs before and after treatment were observed, Lysholm scoring were used to evluated clinical efficacy.
RESULTSAll patients were followed up from 16 to 30 months with an average of 21.6 months. The stability of knee joints was good in all patients. Abduction stress test was negative when the knee joint was straightened at 0 degrees and flexed at 30 degrees. The average degree of flexed knee (67.00 +/- 5.80) degrees preoperatively was lower than that of postoperatively (136.50 +/- 6.30) degrees at 1 year. According to Lysholm scoring, preoperative scores ranged from 30 to 43 points, averaged 36.46 +/- 1.48; 1 year after operation ranged from 87 to 100 with an average of 91.50 +/- 3.80 and higher than postoperative. Twenty patients got an excellent results, 5 good and 2 fair.
CONCLUSIONSuture anchors in treating acute injuries of medial collateral ligament of knee at degree III has following advantages: small range of tissue dissection, easy to operate, reliable fixation and less complications.

OBJECTIVETo investigate the effects of valsartan on expression of angiotensin II receptors in different regions of heart after myocardial infarction (MI).
METHODSCanines were divided into sham-operated control group (n=7), infarction group (n=7) and Valsartan group (10 mg x kg(-1) x day(-1) for 4 weeks after MI operation, n=7). Four weeks after operation, Doppler tissue imaging (DTI) was used to evaluate regional ventricular function in the noninfarcted myocardium (apical and basal near to the infarction region). The mRNA and protein expressions of angiotensin II type 1 receptor (AT1-R) and angiotensin II type 2 receptor (AT2-R) on the corresponding regions were detected by competitive reverse-transcriptase polymerase chain reaction technique and immunohistochemical technique respectively. Results The protein and mRNA expressions of AT1-R were significantly increased in both apical and basal regions near to the infarction in dogs with MI compared with those in control group (P < 0.05) which could be downregulated by valsartan (P < 0.05). AT2-R expressions were significantly upregulated in infarction group in both apical and basal regions compared with those in control group and valsartan further increased AT2-R expressions in both areas (P < 0.05). Myocardial peak systolic velocity (Sm), myocardial peak early diastolic velocity (Em) and myocardial peak late diastolic velocity (Am) at both apical and basal regions near to the infarction regions were significantly lower in MI group than those in the control group which could be significantly improved by valsartan.
CONCLUSIONBoth mRNA and protein expressions of AT1-R and AT2-R are upregulated in noninfarcted regions near MI, valsartan improved myocardial function via inhibiting AT1-R upregulation and enhancing AT2-R upregulation.

OBJECTIVETo develop an HPLC method for determining oxyphyllenodiol A (1) and teuhetenone A (2) contained in Alpinia oxyphylla and to compare the contents of the two components contained in medicinal materials and prepared herbal medicines in pieces sold in the market and different fractions.
METHODHPLC and Waters sunfire C18 column (4. 6 mm x 250 mm, 5 microm) were adopted for gradient elute with the mobile phase of acetonitrile and water. The flow rate was 1.0 mL x min(-1) and the detection wavelength was 250 nm.
RESULT1 and 2 showed a good linear relationship within the range of 0.1296 - 0.8640 microg and 0.1635 - 1.0900 microg respectively, with the average recoveries of 99.08% and 97.80%. Their content ranges were 0.0059% - 0.0149% and 0.0080% - 0.0164% in different samples. The mean value of 1 and 2 were 0.0085% and 0.0104% in the whole fruits, and 0.0137% and 0.0157% in the seeds. They were undetected in the nutshells.
CONCLUSIONThe method is so precise, accurate and highly reproducible that it can be used to determine the contents of oxyphyllenodiol A and teuhetenone A in A. oxyphylla. The contents of the two components are mainly extracted from the seeds, with certain difference among different samples. There are a higher contents and no significant difference in the salted and raw seeds.
