This study was purpose to examine the effect of dimethyl sulfoxide (DMSO) and Tween 80 on the growth and viability of stromal cells (BMSC), colony-forming units for granulocytes and macrophages (CFU-GM) and bone marrow endothelial cell line (BMEC) from murine bone marrow in vitro, and to analyze the concentration-effect relationship. The colony yields of colony-forming units fibroblastic (CFU-F) and CFU-GM were assessed in the murine bone marrow cell cultures at various concentrations of DMSO or Tween 80 and in the control groups. The MTT assay and trypan blue exclusion were used to determine the cell viability and percentage of survival in BMSC and BMEC cultures with or without either of these organic solvents. The results showed that the colony yields of both CFU-F and CFU-GM were decreased significantly (p<0.05 or <0.01) at the concentrations (v/v final) of 2% DMSO or 0.005%-0.01% Tween 80 respectively, as compared with control. The cell viability and percentage of survival of BMSC and BMEC cultures were significantly reduced (p<0.05 or <0.01) at 0.5%-1.0% DMSO or 0.002%-0.005% Tween 80, as compared with control. With the increase of volume fractions of these solvents, the decreased percentages of corresponding measurements were increased by degrees. It is concluded that when the concentration of DMSO or Tween 80 goes to a certain level in cell culture medium, either of the organic solvents has an inhibitory action or/and cytotoxicity on the growth and viability of BMSCs, CFU-GM and BMECs. The growth inhibition and cytotoxic response are more significant at higher concentrations of these solvents.

To study the effect of alpha1-acid glycoprotein 1 (ORM1) polymorphism on the concentration of free nortriptyline in serum, genotyping analysis was employed in ORM1 by sequencing. Eighteen unrelated male adults were chosen and given a single dose of 25 mg nortriptyline orally, then the blood samples were taken at 0, 1, 2, 3, 4, 6, 8, 12, 24, 32, 48, 72, 96 and 168 hours after drug administration. Nortriptyline and 10-OH-nortriptyline in serum and ultrafiltrate were detected for the total and free concentration by using HPLC-MS/MS. Pharmacokinetic parameters were compared among different ORM1 genotypes. No significant differences were shown in the pharmacokinetic parameters of total nortriptyline and 10-OH-nortriptyline. The mean AUC(0-infinity) of free nortritpyline in ORM1 * F/ * F1 subjects was significantly higher than that in ORM1 * F1/ * S and ORM1 * S/ * S subjects [(119.1 +/- 74.4) ng x mL(-1) x h vs (51.4 +/- 23.2) ng x mL(-1) x h and (42.4 +/- 11.6) ng x mL(-1) x h]. The percentage of protein binding in subjects with ORM1 * F1/ * F1 genotype at 2, 3, 4, 6, 8 and 12 h after administration was slightly lower than in those with ORM1 * F1/ * S and ORM1 * S/ * S genotypes while the distinct difference was shown at 4 h (P < 0.05). Different ORM1 genotypes might affect the protein binding percentage and the concentration of serum free nortriptyline. The ability binding to the drug was higher in subjects with ORM1 * S/ * S genotype than in those with other two genotypes, so as to cause the lower concentration of free nortriptyline.

PURPOSE: Tumor protein p53-regulated apoptosis-inducing protein 1 (TP53AIP1) functions in various cancers. We studied the effect and molecular mechanism of TP53AIP1 in breast cancer. METHODS: The degree of correlation between TP53AIP1 expression and overall survival in patients with breast cancer was obtained from the online The Cancer Genome Atlas database. Six of the TP53AIP1 levels in the tumor and adjacent non-tumor tissues randomly selected from 38 breast cancer patients were determined. Transgenic technology was used to enhance the expression of TP53AIP1 in breast cancer cell lines, MDA-MB-415 and MDA-MB-468, and to observe the effects of gene overexpression on the proliferation, cell cycle, and apoptosis of breast cancer cells. The molecular mechanism of association between cell cycle- and apoptosis-related factors and the phosphoinositide 3-kinases/protein kinase B (PI3K/Akt) pathway was also studied. RESULTS: The messenger RNA and protein expression levels of TP53AIP1 in cancer tissues were significantly lower than those in the control group. TP53AIP1 overexpression inhibits cell viability. The mechanism of TP53AIP1 inhibition of proliferation and growth of breast cancer cells includes cell cycle arrest, apoptosis promotion (p < 0.01), promotion of the expression of cleaved-caspase-3 (p < 0.01), cleaved-caspase-9 (p < 0.01), B cell lymphoma/leukemia-2 (Bcl-2)-associated X protein, and p53 (p < 0.01), and the inhibition of Bcl-2, Ki67, and PI3K/Akt pathways (p < 0.01). CONCLUSION: TP53AIP1 may be a novel tumor suppressor gene in breast cancer and can potentially be used as an effective target gene for the treatment of breast cancer.

OBJECTIVE: To observe the difference in the therapeutic effects on rheumatoid arthritis (RA) between the combined -deep needling and bloodletting technique and the regular needling technique. METHODS: A total of 70 patients were randomized into an observation group (35 cases) and a control group (35 cases, 4 cases dropped-out). Dazhui (GV 14), Shenzhu (GV 12), Zhiyang (GV 9), Jinsuo (GV 8), Ganshu (BL 18), Shenshu (BL 23), Zhibian (BL 54), Weizhong (BL 40), Taixi (KI 3) and Tianzong (SI 11), etc. were selected in the two groups. Additionally, in the observation group the -deep needling technique was adopted at Tianzong (SI 11) and Zhibian (BL 54), the bloodletting technique at the local swollen area and the even-needling technique at the rest acupoints. In the control group, the even-needling technique was applied to all of the acupoints. Acupuncture treatment was given once every two days, 3 times a week and for 12 weeks totally. The numbers of tender points at the knee joint, the numbers of swollen sites at the knee joint, the visual analogue scale (VAS) score and the American health assessment questionnaire (HAQ) score were observed in the two groups before and after treatment, as well as the changes in erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP). The American College of Rheumatology (ACR) criteria was adopted to evaluate the therapeutic effects of the two groups. RESULTS: After treatment, the numbers of tender points, the numbers of swollen sites, VAS score and HAQ score were all improved as compared with those before treatment in the two groups (all <0.01), and the results in the observation group were better than those in the control group (all <0.05). After treatment, ESR and CRP levels were all reduced as compared with those before treatment in the two groups (all <0.01), but there was no significant differences between the two groups (both >0.05). The standard-reaching rates of ACR 20 and ACR 50 in the observation group were 94.3% (33/35) and 31.4% (11/35) respectively, which were better than 67.7% (21/31) and 6.5% (2/31) in the control group (<0.01, <0.05). CONCLUSION The acupuncture with the -deep and bloodletting techniques and the acupuncture with regular needling technique are all effective on RA. The therapeutic effects of the acupuncture treatment with the -deep and bloodletting techniques are better than that with regular needling technique.

OBJECTIVETo observe the clinical efficacy differences between different needling methods for dry eye syndrome.

METHODSSixty patients of dry eye syndrome were randomly divided into an observation group and a control group, 30 cases (60 eyes) in each group. Shangjingming (Extra), Xiajingming (Extra), Tongziliao (GB 1), Cuanzhu (BL 2), Fengchi (GB 20), Hegu (LI 4), Sanyinjiao (SP 6), Taixi (KI 3) and Taichong (LR 3) were selected in the two groups. The control group was treated with conventional acupuncture, while the observation group was treated with guiding-acupuncture. Electroacupuncture (EA) was used at bilateral Tongziliao (GB1) and Cuanzhu (BL 2), 30 min per treatment. The treatment was given three times per week. Totally 1-month treatment (12 treatments) was given. The eye symptom score, breakup time of tear film (BUT), Schirmer Ⅰ test (SⅠT) and visual analogue scale (VAS) score were compared before and after treatment in the two groups. The clinical efficacy was compared between the two groups.

RESULTSCompared before treatment, the eye symptom score, BUT, SⅠT and VAS score were improved after treatment in the two groups (all<0.001); the improvements of eye symptom score and SⅠT in the observation group were superior to those in the control group (both<0.05). The differences of BUT and VSA score between the two groups were not significant (both>0.05). The total effective rate was 86.7% (52/60) in the observation group, which was superior to 73.3% (44/60) in the control group (<0.05). .

CONCLUSIONThe conventional EA and guiding-acupuncture combined with EA are both effective for dry eye syndrome, and the efficacy of guiding-acupuncture combined with EA is superior to that of conventional EA.

OBJECTIVETo assess the effects of early intestinal application of sijunzi decoction (SJZD) on the immune function in post-operational patients of gastrointestinal tumor.

METHODSNinety-two patients with malignant gastrointestinal tumor were randomly divided into two groups. Patients in both groups were given the isocaloric and isonitrogenous enteral nutritional support starting from the first day after operation for 1 week, but to the tested group, SJZD was given additionally. The concentration of serum cytokines such as interleukin-1 (IL-1), interleukin-2 (IL-2), interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-alpha), the peripheral blood cell counts of total lymphocyte, T-lymphocyte, B lymphocyte, and T lymphocyte subsets (CD3, CD4, CD8, CD4/CD8) as well as the levels of IgA, IgG, IGM and C-reactive protein (CRP) were measured on the day before operation, the first morning after operation and at the end of study.

RESULTSAt the end of the study, the concentration of IgA, IgG, 1gM, number of total lymphocyte, CD3, CD4 and CD4 lCD8, and serum IL-2 were obviously higher (P < 0.05), and levels of IL-6, TNF-alpha and CRP were obviously lower in the tested group than those in the control group (P < 0.05).

CONCLUSIONEarly application of SJZD on the base of enteral nutritional therapy can lessen the degree of post-operational stress and inflammatory response, and enhance the immune function of patients.

OBJECTIVE: Psoriasis is a common chronic inflammatory skin disease that is prone to recurrence, and the proinflammatory factor, cysteine-rich protein 61 (Cyr61), is important in its pathophysiology. Long-term clinical practice has shown that Sancao Formula (SC), a Chinese herbal compound, is effective in the treatment of psoriasis, but the precise mechanism remains unknown. In this study, we investigate the mechanism by which SC extract alleviates imiquimod (IMQ)-induced psoriasis. METHODS: The expression of Cyr61 in psoriatic lesions and normal healthy skin was detected using immunohistochemical analysis to investigate the biological role of Cyr61 in models of psoriatic inflammation. A psoriatic mouse model was established by topical application of IMQ, and the effect of topical application of SC extract was evaluated using the psoriasis area and severity index (PASI) score, hematoxylin-eosin staining, and histopathological features of the skin. Next, a HaCaT cell inflammation model was established using interferon-γ (IFN-γ), and the effect of SC extract on the mRNA and protein levels of Cyr61 and intercellular cell adhesion molecule-1 (ICAM-1) was confirmed using Western blot and quantitative real-time polymerase chain reaction analyses. RESULTS: Immunohistochemical staining showed that the expression of Cyr61 in psoriatic lesions was higher than that in normal skin samples (78.26% vs 41.18%, P < 0.05), and the number of Cyr61-positive cells in psoriatic lesions was also significantly higher than in normal skin (18.66 ± 2.51 vs 4.33 ± 1.52, P < 0.05). Treatment in mice with IMQ-induced psoriasis showed that SC extract could significantly improve the inflammatory phenotype, PASI score (10.875 ± 0.744 vs 3.875 ± 0.582, P < 0.05), and pathological features compared with those in IMQ model group; SC treatment was also associated with decreased levels of Cyr61 and ICAM-1. In the IFN-γ-induced inflammatory cell model, the mRNA and protein levels of Cyr61 and ICAM-1 were upregulated, while the SC extract downregulated the levels of Cyr61 and ICAM-1. CONCLUSION The results provide a theoretical basis for the involvement of Cyr61 in the pathogenesis of psoriasis, and suggest that SC should be used to target Cyr61 for the prevention of psoriasis recurrence.

OBJECTIVETo observe the effects of different anesthesia ways on endorphin and hemodynamics of laparoscopic cholecystectomy patients in the perioperative phase.

METHODSA total of 90 laparoscopic cholecystectomy patients, 29 to 80 years old, were randomly assigned to Group A (treated with electroacupuncture at acupoints combined general anesthesia), Group B (treated with electroacupuncture at non-acupoints combined general anesthesia), and Group C (treated with general anesthesia) according to American Society of Anesthesiologists (ASA) I-II, 30 cases in each group. All patients were induced by 3 microg/kg Fentanyl (Fen), 2 mg/kg Propofol (Pro), and 0.1 mg/kg Vecuronium (Vcr). Bispectral index (BIS), being 40 -65, indicated the state of general anesthesia. The anesthesia was maintained by intravenous injecting Pro, interruptedly intravenous injecting Fen and Vcr. Each patient received patient controlled intravenous analgesia (PCIA) after operation. On these bases, patients in Group A received electrical acupuncture at bilateral Hegu (LI4), Neiguan (PC6), Quchi (Ll11), Zusanli (ST36), and Yanglingquan (GB34). Patients in Group B received electrical acupuncture at the points beside acupoints. The electroacupuncture was lasted from 15 -30 min before anesthesia induction to the end of the operation in Group A and B. The heart rate (HR), mean arterial pressure (MAP), cardiac index (CI), cardiac output (CO), systemic vascular resistance index (SVRI), and acceleration index (ACI) were recorded before anesthesia induction, immediate before pneumoperitoneum, 5 min after pneumoperitoneum, excision of gallbladder, and at the end of operation. The time consumption from discontinuation to spontaneously breathing recovery, analeptic, and extubation were recorded. The blood samples (3 mL each time) were collected from the peripheral vein before anesthesia induction, 2 h after operation, the 1st day after operation, and the 3rd day after operation to detect the beta-endorphin (beta-EP) level. The visual analogue scale (VAS) were observed and recorded in the 3 groups at post-operative 4, 6, 8, 24, and 44 h, respectively.

RESULTS(1) Compared with before anesthesia induction in the same group, the CI, CO, ACI of all patients decreased significantly at 5 min after pneumoperitoneum and at excision of gallbladder (P < 0.01, P < 0.05). The HR, MAP, SVRI obviously increased in Group B and Group C at each time point (P < 0.05, P < 0.01). Less change happened in Group A. Compared with Group C, the increment of MAP was less in Group A at 5 min after pneumoperitoneum, showing statistical difference (P < 0.05). (2) The time consumption from discontinuation to analeptic and extubation was obviously shorter in Group A than in Group B and Group C (P < 0.05, P < 0.01). (3) The level of beta-EP on the 1st day of operation was significantly lower in Group A than in Group B (P < 0.05) and Group C (P < 0.01). (4) The VAS score at post-operative 44 h was significantly lower in Group A than in Group B and Group C (P < 0.05).

CONCLUSIONSElectroacupuncture at acupoints combined general anesthesia could maintain the stabilization of haemodynamics, and relieve the stress reaction after pneumoperitoneum and operation, and prolong it to early post-operative period, and strengthen the effects of post-operative analgesia. The post-operative recovery was fast, safe, and reliable.

OBJECTIVETo investigate the effect of acupuncture on blood oxygen saturation in the patient of obstructive sleep apnea-hypopnea syndrome (OSAHS) in sleeping and to evaluate the therapeutic effect of acupuncture on this disease.

METHODSThirty cases with OSAHS were treated with acupuncture at Shanglianquan (Extra), Fengfu (GV 16), Yamen (GV 15), Fengchi (GB 20), etc. 3-5 sessions each week. After treatment of 30 sessions, apneahypopnea index (AHI), mean blood oxygen saturation (MSaO2), the lowest blood oxygen saturation (LSaO2), oxygen desaturation > or = 4% index (ODI4), the mean blood oxygen saturation of oxygen desaturation when SaO2 < 90%, the longest time of oxygen saturation > or = 4% were observed before and after treatment.

RESULTSThe effective rate of acupuncture was 23.3% for OSAHS. After acupuncture, AHI and ODI4 significantly reduced (P < 0.01); LSaO2 significantly increased (P < 0.01); MSaO2 and the mean blood oxygen saturation of oxygen desaturation when SaO2 < 90% significantly enhanced (P < 0.05); the longest time of oxygen saturation > or = 4% did not significantly change.

CONCLUSIONThe acupuncture treatment has intervenient effect on OSAHS and alleviates anoxia, so acupuncture is one of therapies improving anoxia in patients of OSAHS.
