OBJECTIVETo observe the inhibitory effect of 4-chlorobenzoyl berbamine (BBD9) on imatinib-resistant cell line K562 (K562/IR) in vitro and in vivo and explore the mechanisms.

METHODSThe IC50 of BBD9 and berbamine (BBM) was determined by MTT assay. The expressions of p210(Bcr-Abl), IKKa, cytoplasmic and nuclear NF-κBp65 were determined using Western blotting in K562/IR cells following a 48-h exposure to 0.5 µg/ml BBD9 or 8 µg/ml BBM. Flow cytometry was used to analyze the cell viability, apoptosis and necrosis; Western blotting was employed to determine the expressions of PARP, caspase-3, caspase-9 and LC3II in K562/IR cells exposed to different concentrations of BBD9 for 48 h. In nude mouse models bearing K562/IR cell xenograft, the tumor weight, tumor regression, and body weight changes of the mice were measured after treatments with 15 mg/kg and 30 mg/kg BBD9 and 100 mg/kg imatinib.

RESULTSThe IC50 of BBD9 and BBM was 0.73 µg/ml and 5.43 µg/ml, respectively. In K562/IR cell cultures, the expressions of p210(Bcr-Abl), IKKa and nuclear NF-κB p65 were all decreased following BBD9 and BBM treatments, but BBD9 produced more potent effect; cytoplasmic NF-κB p65 showed no obvious changes after the treatments. The cell apoptosis and necrosis increased with the concentrations of BBD9, which also dose-dependently increased the levels of cleaved caspase-3, csapase-9, PARP, and LC3II expression. In the tumor-bearing mouse model, BBD9 showed stronger effects than imatinib in reducing the tumor weight, promoting tumor regression, and increasing the body weight.

CONCLUSIONBBD9 can effectively inhibit the growth of K562/IR cells in vitro and in vivo by activating cell apoptosis, necrosis and autophage pathways, down-regulating expressions of p210(Bcr-Abl) and IKKa and suppressing the cytoplasm-to- nucleus translocation of NF-κBp65.

Objective: To understand the effect of dobutamine on the integrated backscatter of myocardium. Methods: Nineteen open-chest dogs were detected by HP Sonos 5500 with S8 transducer, and the WT, AIBS and CVIB were measured before and after the dobutamine stress. Results: During the dobutamine stress, following the increase of WT, the transmural, subepicardial and subendocardial CVIB all increased. And the increase of subepicardial CVIB was greater than that of subendocardial CVIB, leading to the decrease of TGI. But the AIBS didn't change significantly in the whole process. Conclusion: Dobutamine can enhance myocardium CVIB but has no obvious infleunce on AIBS.

To investigate the influence of such individual factors as gender, age and tissues in vitro to the postmortem interval (PMI) by the Fourier transform infrared (FTIR) spectrometer in animal experiments. SD rats were classified into male and female groups, different age groups (21-day, 42-day and 63-day group), and tissues in vitro and in vivo groups. The rats were sacrificed by cervical dislocation, whose bodies were kept in a controlled environmental chamber set at (20+/-2) degrees C and 50% humidity. The liver, kidney, spleen, myocardium, brain, lung and skeletal muscle tissues were collected for measurement from time zero to 48 h postmortem. With the change of PMI, no obvious changes were found in the main FTIR absorbance peaks and their ratios at different time points. All the experimental groups showed no significant changes when compared with the controls. The gender, age and tissues in vitro were not found to be contributing factors in the estimation of PMI via FTIR spectroscopy.

Objective To study the therapeutic effects of acupuncture therapy for prevent pain of replantation of severed finger. Methods Totals of 80 patients were randomly divided into two groups from March 2012 to March 2014. Patients in the treatment group were treated with acupuncture therapy, and patients in the control group were treated with routine care. Results The pain scores of 4, 6, 12, 24 and 48 hours after the treatment in the treatment group were (2. 13 ± 0. 33), (2. 75 ± 0. 67), (3. 25 ± 0. 59), (3. 43 ± 0. 78) and (2.85 ±0.62), which were significantly lower than those in the control group (t =2. 421, 2. 270, 7. 223, 7. 614, 4. 106, respectively;P<0. 05). In the treatment group, one case had vascular crisis, with an incidence of 2. 5%. In the control group, four cases had vascular crisis, with an incidence of 15. 0%, there was a significant difference between the two groups (χ2 =2. 165,P<0. 05). One case in the treatment group had diclofenac sodium suppositories, with an incidence of 2. 5%. While seven cases had diclofenac sodium suppositories, with an incidence of 17. 5% in the control group, there was a significant difference between the two groups (χ2 =2. 287,P<0. 05). Conclusions Acupuncture therapy can significantly reduce postoperative pain and reduce the incidence of vascular crisis, it is worthy of promotion.

BACKGROUNDThe development of new adjuvants for human use has been the focus of attention. This study's aim is to explore the possibility of using nanoparticle Ca nanoparticles (CA) as a vaccine adjuvant of anti-idiotypic antibody NP30 against schistosomiasis and its protective mechanisms.

METHODSNanoparticle CA-NP30 conjugate (CA-NP30) was fabricated. BALB/c mice were immunized actively with CA-NP30 to evaluate its effects of protective immunity on mice. The serum levels of specific IgG, IgG1 and IgG2a antibodies against NP30 and the concentrations of IFN-gamma and IL-4 in supernatant of splenocytes were determined via ELISA.

RESULTSNanoparticle CA could enhance significantly the protective immunity of NP30 against infection of Schistosoma japonicum and the worm reduction rose from 36.0% (NP30 alone) to 52.6%. The serum levels of specific IgG, IgG1 and IgG2a antibodies against NP30 increased remarkably, as compared with those of the group immunized with NP30 alone. The concentration of IFN-gamma in supernatant of splenocyte was drastically elevated [the groups immunized with CA-NP30 and NP30 alone were (493.80 +/- 400.74) pg/ml and (39.03 +/- 39.58) pg/ml, respectively], but the concentration of IL-4 showed no significant difference from that of NP30 alone [(27.94 +/- 9.84) pg/ml vs (27.28 +/- 14.44) pg/ml].

CONCLUSIONSNanoparticle CA could act as a vaccine adjuvant of anti-idiotypic antibody NP30 against schistosomiasis. The mechanism could be that CA-NP30 enhances humoral and cellular immune responses in mice.

The release kinetics research of sustained-release formulations of traditional Chinese medicines (TCM) is an inalienable part of the chain of TCM modernization, which plays an important role in the development of modern compound TCM preparation. However, the research method or pattern in line with the specific characteristics of TCM, i.e., multi-component and multi-target, is still lacking. On the basis of material rough set theory, this paper reviewed the advantages and disadvantages of the existing evaluation patterns and methods, a tentative idea about the "total amount" release characteristics evaluation on TCM compound sustained-release preparation has suggested so as to evaluate the release kinetics and to promote the development of evaluation methodology on TCM sustained-release preparations.

OBJECTIVETo evaluate the outcome of in vitro fertilization embryo transfer (IVF-ET) in treatment of polycystic ovarian syndrome (PCOS) with infertility.

METHODSA retrospective analysis was performed from 52 patients with PCOS (PCOS group) and 408 cases with tubal infertility (control group). Both groups underwent IVF-ET treatment from 2001 to 2004. The duration of stimulation, amps of gammaFSH, the level of serum E2, P on the day of HCG injection, the number of oocytes retrieved, the rates of fertilization, cleavage, implantation and pregnancy, the incidence of ovarian hyperstimulation syndrome (OHSS) and cancelled rate of ET were compared between the two groups.

RESULTThe duration of stimulation and amps of gammaFSH were not significantly different between the two groups. The concentration of serum E2, P on the day of HCG injection, the numbers of oocytes retrieved and cleavaged embryos were significantly higher in PCOS group (P <0.01, <0.05). Fertilization rate was significantly lower in PCOS group (P <0.01). The implantation, pregnancy and miscarriage rates per ET were not statistically significant. The OHSS rates and cancelled rates of ET were higher in PCOS group (P <0.01).

CONCLUSIONWomen with PCOS have a lower fertilization rate compared with those with tubal-factor fertility during IVF-ET. However, more oocytes are recovered and the preimplanted embryo has a normal chance of implantation leading to similar pregnancy rates. The OHSS rates and cancelled rates of ET are higher in PCOS because of a greater number of oocytes developed and a higher level of E2.

OBJECTIVETo explore the effect of acupuncture-drug compound anesthesia on immune function in patients with extracorporeal circulation undergoing cardiac surgery.

METHODSThirty cases undergoing cardiac surgery which included atrial septal defect neoplasty, ventricular septal defect neoplasty, mitral valve replacement and pulmonary valve coarctotomy were randomly divided into group A and group B, 15 cases in each group. Group A was given general anesthesia plus acupuncture at Neiguan (PC 6), Lieque (LU 7) and Yunmen (LU 2), and group B was given simple general anesthesia. Tumor necrosis factor-alpha (TNF-alpha), interleukin-2 (IL-2) and interleukin-10 (IL-10) levels before and after surgery were compared.

RESULTSThe level of TNF-alpha was increased and the levels of IL-2 and IL-10 in the serum were decreased in both groups after extracorporeal circulation for 2 h and 24 h, and the ranges of all changes were more less in group A (all P < 0.05).

CONCLUSIONCompared with simple general anesthesia, acupuncture-drug compound anesthesia can improve immune suppression partially in the perioperative periods under the same conditions of controlling anesthesia degree.
