DT-13, a saponin of dwarf lilyturf tuber,exhibits anti-cancer activity by down-regulating C-C chemokine receptor type 5 and vascular endothelial growth factor in MDA-MB-435 cells简

AIM： To investigate the anticancer activity of DT-13 under normoxia and determine the underlying mechanisms of action. METHODS： MDA-MB-435 cell proliferation, migration, and adhesion were performed to assess the anticancer activity of DT-13, a saponin from Ophiopogonjaponicus, in vitro. In addition, the effects of DT-13 on tumor growth and metastasis in vivo were evaluated by orthotopic implantation of MDA-MB-435 cells into nude mice; mRNA levels of vascular endothelial growth factor （VEGF）, C-C chemokine receptor type 5 （CCR5） and hypoxia-inducible factor 1a （HIF-1a） were evaluated by real-time quantitative PCR; and CCR5 protein levels were detected by Western blot assay. RESULTS： At 0.01 to 1 umol·L -1, DT-13 inhibited MDA-MB-435 cell proliferation, migration, and adhesion significantly in vitro. DT-13 reduced VEGF and CCR5 mRNAs, and decreased CCR5 protein expression by down-regulating HIF-1 a. In addition, DT-13 inhibited MDA-MB-435 cell lung metastasis, and restricted tumor growth slightly in vivo. CONCLUSION： DT-13 inhibited MDA-MB-435 cell proliferation, adhesion, and migration in vitro, and lung metastasis in vivo by reducing VEGF, CCR5, and HIF-la expression.     

Effects of feeding tyrosine and phenylalanine on the accumulation of phenylethanoid glycosides to Cistanche deserticola cell suspension culture

AIM： To investigate the effects of feeding phenylalanine （Phe） and tyrosine （Tyr） on the accumulation of total phenolic compounds and four phenylethanoid glycosides （PeGs） to a cell suspension culture of the parasitic plant Cistanche deserticola.METHOD： A cell suspension culture of C. deserticola was established and precursors of different concentrations were fed. In each group, the cell was sampled at the 24^th day after inoculation. The content of total phenolic compounds and four PeGs compounds were determined using the Folin-Ciocalteu method and an HPLC method, respectively.RESULTS： In the Phe fed cells, the maximum PeGs yield was achieved when Phe was fed at 1.5 mmol·L^-1 and the yield reached 1.13 times the control cell concentration. In the Tyr fed cells, the maximum yield of PeGs was 1.60 times of control when 0.75 mmol·L^-1 Tyr was fed to the cells. Furthermore, it was found that the salidroside yield was 4.01 times of control group when 5 mmol·L^-1 Tyr was fed.CONCLUSION： Tyr is a better precursor for PeGs accumulation compared with Phe, and the rate limiting enzymes might be involved in the Tyr branch.     

Qingkailing injection for the treatment of acute stroke： a systematic review and Meta-analysis

OBJECTIVE: To evaluate systematically the clinical efficacy and safety of Qingkailing(QKL) injection in the treatment of acute stroke.METHODS: Searches for randomized controlled trials into acute stroke treated with QKL injection were performed in the China National Knowledge Infrastructure Database, China Science and Technology Journal Database, Wan fang Database,Chinese Biomedical Literature Database, PubMed and Cochrane Library, from January 1979 to March2013. Two reviewers independently retrieved the RCTs and extracted the information. The Cochrane risk of bias method was used to assess the quality of the included studies, and a Meta-analysis was conducted with Review Manager 5.2 software.RESULTS: A total of 13 studies with 1110participants were included. The quality of the studies was generally low. The Meta-analysis indicated that the combined use of QKL and Western Medicine was significantly superior to control group therapy in terms of the total effective rate. The relative risk(RR) in the acute cerebral hemorrhage(ACH) sub-group was 1.17 [95%confidence interval(CI)(1.08, 1.26), P=0.0001]. In the acute cerebral infarction(ACI) sub-group, RR was 1.27 [95% CI(1.14, 1.42), P0.0001], and in the ACH and ACI mixed sub-group, RR was 1.34 [95% CI(1.20,1.50),P0.00001]. Additionally, QKL promoted the absorption of hematoma [mean difference(MD)=﹣3.73, 95%CI(﹣4.48, ﹣2.98), P0.000 01],decreased neurological damage in ACI [MD=﹣5.60, 95% CI(﹣8.50, ﹣2.70), P=0.0002] and ACH[MD= ﹣ 4.08, 95% CI( ﹣ 8.00, ﹣ 0.16), P=0.04],promoted the recovery of awareness [RR=1.56, 95%CI(1.09, 2.21), P=0.01] and reduced the whole blood viscosity coefficient [MD=﹣ 0.75, 95% CI( ﹣1.47, ﹣0.03), P=0.04]. There were no adverse drug reactions reported in the included studies.CONCLUSION: Based on this systematic review,QKL combined with conventional therapy was effective compared with control treatment.However, because the articles used in the study were not of high quality, further studies should be conducted into the efficacy and safety of QKL in treating acute stroke.     

Characterization and evaluation in vivo of baicalin-nanocrystals prepared by an ultra-sonic-homogenization-fluid bed drying method简

AIM： To improve the absorption and bioavailability of baicalin using a nanocrystal （or nanosuspension） drug delivery system. METHODS： A tandem, ultrasonic-homogenization-fluid bed drying technology was applied to prepare baicalin-nanocrystal dried powders, and the physicochemical properties of baicalin-nanocrystals were characterized by scanning electron microscopy, photon correlation spectroscopy, powder X-ray diffraction, physical stability, and solubility experiments. Furthermore, in situ intestine single-pass perfusion experiments and pharmacokinetics in rats were performed to make a comparison between the microcrystals of baicalin and pure baicalin in their absorption properties and bioavailability in vivo. RESULTS： The mean particle size of baicalin-nanocrystals was 236 nm, with a polydispersity index of 0.173, and a zeta potential value of-34.8 mV, which provided a guarantee for the stability of the reconstituted nanosuspension. X-Ray diffraction results indicated that the crystallinity of baicalin was decreased through the ultrasonic-homogenization process. Physical stability experiments showed that the prepared baicalin-nanocrystals were sufficiently stable. It was shown that the solubility of baicalin in the form of nanocrystals, at 495 ug·mL-1, was much higher than the baicalin-microcrystals and the physical mixture （135 and 86.4 ug·mL- 1, respectively）. In situ intestine perfusion experiments demonstrated a clear advantage in the dissolution and absorption characteristics for baicalin-nanocrystals compared to the other formulations. In addition, after oral administration to rats, the particle size decrease from the micron to nanometer range exhibited much higher in vivo bioavailability （with the AUC（0-t） value of 206.96 ± 21.23 and 127.95 ± 14.41 mg·L-1·h-1, respectively）. CONCLUSION： The nanocrystal drug delivery system using an ultrasonic-homogenization-fluid bed drying process is able to improve the absorption and in vivo bioavailability of baicalin, compared with pure baicalin coarse powder and micronized baicalin.     

Hypercoagulability in cancer patients grouped by syndromes differentiated with the theory of abnormal hilit in traditional Uyghur medicine

OBJECTIVE： To investigate the relationship in ma- lignant-neoplasm patients of hypercoagulability between syndromes differentiated with the theory of abnormal hilit in traditional Uyghur medicine（TUM）. METHODS： A total of 248 patients with malignant tumors were enrolled. Based on the theory of TUM they were divided into two groups： abnormal Sav- da and abnormal Non-Savda（including abnormal Khan, abnormal Sepra and abnormal Belghem types）; fifty healthy volunteers were selected as controls. Platelet（PLT）, prothrombin time（PT）, plas- ma fibrinogen（FIB）, thrombin time（TT）, activated partial thromboplastin time（aPTT） and D-Dimer（D-D） were measured in both groups. RESULTS： Compared with the control and abnor-mal Non-Savda groups, in the abnormal Savda group the PLT count increased（P0.05）, the PT was lengthened（P0.01）, and the FIB significantly in- creased（P0.01）. D-Ds in the three groups were sig- nificantly different（P0.05）. No significant differ- ence was found inTT and aPTT values（P0.05）. CONCLUSION： Hypercoagulability existed in pa- tients with malignant tumors in the different types of TUM syndromes, especially in the abnormal Sav- da group; this was characterized by increased blood viscosity, platelet aggregation and thrombo- sis. D-D appears to be a significant predictor for the therapeutic effect of TUM in relation to malignant tumor therapies.     

Capillary blood flow in patients with dysmenorrhea treated with acupuncture

OBJECTIVE; To observe capillary blood flow at acu- points during acupuncture treatment of primary dysmenorrhea and gain new insights into its anal- gesic mechanism. METHODS： Patients with primary dysmenorrhea were enrolled and randomly assigned to a treat- ment or control group. Subjects＇ symptoms were differentiated into various Traditional Chinese Medi- cine （TCM） syndromes and treated for 10 sessions with puncturing acupuncture or self-pressing right-hand Hegu （LI 4）, adding other acupoints based on syndrome. Laser speckle was used tocompare the change in the vasomotor amplitude and perfusion of the capillaries in Hegu （LI 4） be- fore and during the treatment. Each subject was re- quired to finish the period pain symptoms observa- tion form, verbal rating scales, numerical rating scale, pain rating index, face rating scale, Zung self-rating depression scale, Zung self-rating anxi- ety scale, and numerical rating scale before and af- ter treatments. RESULTS： After 10 sessions, the symptom scores, pain index （PI）, and visual analog scale （VAS） de- creased significantly in treatment group. The vol- ume of blood flow in Hegu （LI 4） declined slightly. No significant evidence supported that needling caused capillary contraction, but the capillary vaso- motor amplitude at Hegu （LI 4） increased remark- ably. CONCLUSION： Acupuncture can increase the capil- lary blood flow, thus promoting the flow of Qi and blood in terms of TCM theory, which facilitates pain relief.

Classification and reduction manipulation of fractures in Chinese traditional Mongolian osteopathy

OBJECTIVE： To explore the concept of classifica- tion and reduction manipulation of fractures in Chi- nese traditional Mongolian osteopathy. METHODS： Based on the linear classification of fractures in Chinese traditional Mongolian osteopa- thy and the practice of reduction manipulation, a dynamic classification and reduction manipulation concept of fractures was established with the use of modern biomechanical principles and methods. RESULTS： We classified the linear classification and reduction manipulation of fractures in Chinese tra- ditional Mongolian osteopathy based on the achievement of fracture line and used the cause of the formation of the fracture line for our dynamic classification and reduction manipulation of frac- tures concept.CONCLUSION： The etiology of the formation of fracture lines can be used to decrease diagnostic er- ror, increase therapeutic effects of manipulation, and further provide a new concept and method for the development of the reduction concept of frac- tures.     

Curative effect of Xuebijing injection on severe pulmonary contu- sion

OBJECTIVE： To investigate the curative effects of Xuebijing （XBJ） injection, a Chinese patent medi- cine, on severe pulmonary contusion （PC）. METHODS： Sixty-three patients with PC were ran- domized to conventional therapy plus XBJ injec- tion （n=33） or conventional therapy alone （n=30）. Between groups differences in corticosteroid treat- ment, immune regulation therapy, hemofiltration, infusion volume, transfusion volume and antibiotic period were measured, as were intensive care unit（ICU）-free time, ventilation time, 28-day mortality rate and incidence of ventilation-associated pneu- monia （VAP）. Serum concentrations of procalcito- nin （PCT）, tumor necrosis factor-a （TNF-a）, interleu- kin （IL）-6, and 11_-10, white blood cell （WBC） counts and percentages of human leukocyte antigen DR/ CD14＋ （HLA-DR/CD14＋） peripheral blood mononu- clear cells were compared. Markers of ventilation were determined by blood gas analysis and ventila- tor parameters. RESULTS： WBC counts and serum concentrations of PCT, TNF-a, 11.-6 and IL-10 were reduced signifi- cantly more quickly, and CD14＋ percentage was in- creased significantly earlier, in the XBJ group than in the control group （P〈0.05 each）. The level of ven- tilation and oxygenation index were ameliorated earlier in the XBJ than in the control group （P〈 0.05）. XBJ treatment significantly reduced ICU-free time, ventilation time and incidence of VAP （P〈0.05 each）, but had no effect on 28-day mortality rate （P〉0.05）. CONCLUSION： XBJ treatment can shorten ICU-free and ventilation times and reduce the incidence of VAP, improving outcomes in patients with severe PC. XBJ may act by regulating inflammation and im- munity, alleviating systemic inflammatory response syndrome induced by trauma.

Effects of Chinese herbs in children with Henoch-Schonlein purpura nephritis：a randomized controlled trial

OBJECTIVE： To research the curative effect of Chi- nese herbs for clearing away heat, promoting diure- sis, nourishing the kidney, and consolidating es- sence in children with Henoch-Schonlein purpura nephritis（HSPN） with internal accumulation of damp-toxin using randomized controlled observa- tions on large samples. To seek the mechanism of the therapy and its scope of indications. METHODS： Overall, 186 children with HSPN were randomly divided into two groups： treatment group（n=126） treated with Chinese herbs for clear- ing heat and promoting diuresis and a control group（n=60） treated with Western Medicine. The treatment was carried out for three courses of 4 weeks each. We recorded changes in patient urine routines, 24 h urinary protein, blood-coagulating series, immunoglobulin and T-cell subgroups, and improvements in main symptoms. We evaluated the alleviation of clinical symptoms and the im- provement of proteinuria, hematuria, and other lab-oratory test results. Finally, we analyzed the patient population suitable for this therapy according to the relationship between the grouping of patient body weight and curative effect. RESULTS： Damp-heat syndrome improved in the treatment group, with a significant difference in to- tal effective rate after a 4-week treatment（χ2= 13.5220, P=0.0002） and in curative rate after a 12-week treatment（χ2=6.3410, P=0.0118）, com- pared to those in the control group.The curative ef- fect in the treatment group was greater than that in the control group but there was no statistical dif- ference between the two groups. The curative ef- fect after a 4-week treatment of patients in the treatment group weighing 30 kg or less based on Traditional Chinese Medicine（TCM） signs and uri- nary protein was significantly greater than that in the control group. However, there was no statistical difference in the curative effect on urinary red cells and various indexes after a 12-week treatment be- tween the two groups. CONCLUSION： Therapy for clearing away heat, pro- moting diuresis, nourishing the kidney, and consoli- dating essence using TCM is effective in children with HSPN from internal accumulation of damp-toxin. The therapy is especially suitable for patients weighing 30 kg or less. The curative effect may be related to the improvement of immune function and blood-coagulation.     

Effect of Morinda officinalis capsule on osteoporosis in ovariectomized rats

AIM： To explore the therapeutic effects ofMorinda officinalis capsules （MOP） on osteoporosis in ovariectomized rats. METHOD： Six-month-old female Sprague-Dawley rats were induced for postmenopausal osteoporosis （PMOP） by bilateral ovariectomy and divided into seven groups as follows： sham-operated group, ovariectomized （OVX） control group, OVX treated with xianlinggubao （XLGB） （270 mg·kg^-1·d^-1） , OVX treated with alendronate sodium （ALN） （3 mg·kg^-1·d^-1）, and OVX treated with Morinda officinalis capsule （MOP） of graded doses （90, 270 and 810 mg·kg^-1·d^-1） groups. Oral treatments were administered daily on the 4th week after ovariectomy and lasted for 12 weeks. The bone mineral density was evaluated by dual-energy X-ray absorptiometry. The tartrate-resistant acid phosphatase （TRAP）, alkaline phosphatase （AKP）, and osteocalcin （OC） levels in the serum and plasma were determined by standard colorimetric and enzyme immunoassays methods. Bone biomechanical properties and morphological parameters were analyzed by three-point bending test and histomorphometry respectively. RESULTS： Morinda officinalis capsules at all doses were able to significantly prevent the OVX-induced loss of bone mass due to diminishing serum AKP and TRAP levels while elevating OC level in the plasma. Morinda officinalis capsules also enhanced the bone strength and prevented the deterioration of trabecular microarchitecture. CONCLUSION： Morinda officinalis capsules possess potent anti-osteoporotic activity in OVX rats which could be an effective treatment for postmenopausal osteoporosis.

Evaluation and SAR analysis of the cytotoxicity of tanshinones in colon cancer cells

AIM： This study was designed to evaluate the anti-cancer actions of tanshinone I and tanshinone IIA, and six derivatives of tan- shinone IIA on normal and cancerous colon cells. Structure activity relationship （SAR） analysis was conducted to delineate the sig- nificance of the structural modifications of tanshinones for improved anti-cancer action. METHOD： Tanshinone derivatives were designed and synthesized according to the literature. The cytotoxicity of different com- pounds on colon cancer cells was determined by the MTT assay. Apoptotic activity of the tanshinones was measured by flow cy- tometry （FCM）. RESULTS： Tanshinone I and tanshinone IIA both exhibited significant cytotoxicity on colon cancer cells. They are more effective in p53＋/＋ colon cancer cell line. It was also noted that the anti-cancer activity of tanshinone I was more potent and selective. Two of the derivatives of tanshinone IIA （N1 and N2） also exhibited cytotoxicity on colon cancer cells. CONCLUSIONS： The anti-colon cancer activity of tanshinone I was more potent and selective than tanshinone IIA, and is p53 dependent. The derivatives obtained by structural modifications of tanshinone IIA exhibited lower cytotoxicity on both normal and colon cancer cells. From steric and electronic characteristics point of view, it was concluded that structural modifications of ring A and furan or dihydrofuran ring D on the basic structure of tanshinones influences the activity. An increase of the delocalization of the A and B rings could enhance the cytotoxicity of such compounds, while a non-planar and small sized D ring region would pro- vide improved anti-cancer activity.

Chaiqinchengqi decoction regulates necrosis-apoptosis via regulat- ing the release of mitochondrial cytochrome c and caspase-3 in rats with acute necrotizing pancreatitis

OBJECTIVE： To explore the effect and the mechanism of Chaiqinchengqi decoction （CQCQD） on the apoptosis-necrosis switch of pancreatic acinar cells in acute necrotizing pancreatitis （ANP） in rats. METHODS： Sixty Sprague-Dawley rats were randomized into the control group, the ANP group and the CQCQD group. The acute pancreatitis （AP） model was induced by intraperitoneal injections of 4 g/kg 8% L-Arginine （PH 7.0） twice with a 1 h inter- val. Rats in the CQCQD group were intragastrically administered CQCQD （20 mL/kg every 2 h, 3 times, then 20 mL/kg every 6 h, 3 times）. Rats were killed at the 6 and 24 h after the induction of AP. The pan- creatic tissues were collected for pathology and to isolate pancreatic acinar cells and mitochondria. RESULTS： CQCQD significantly ameliorated the severity of ANP by reducing the pancreatic histopathology score, indicated by lactate dehydrogenase levels at the 6 and 24 h. The CQCQD group promot- ed the apoptosis of pancreatic acinar cells by rais- ing the apoptosis index compared with the ANP group and the control group. Mitochondrial cytochrome c at the 6 and 24 h in the ANP group were lower than that in the control group or the CQCQD group （0.67±0.13 vs 1.54±0.03 vs 0.81 ±0.09; 0.71± 0.08 vs 1.55±0.09 vs 0.89±0.16, P〈0.01）. The cyto- chrome c levels in the cytoplasm at the 6 and 2 h in the CQCQD group were higher than in the control group （1.36±0.15 vs 0.67±0.04, 1.46±0.08 vs 0.59± 0.09, P〈0.01）, or the ANP group （0.96±0.13, P〉0.05; 0.97±0.09, P〈0.05）. CQCQD increased caspase-3 activity over the ANP group at the 6 h. CONCLUSION： CQCQD can induce apoptosis and relieve the necrosis of pancreatic acinar cells via promoting the release of mitochondrial cytochrome c and increasing pancreatic caspase-3 ac- tivity in ANP rats.
