Objective To observe the effect of modified Bazhen Decoction ( MBD) on bone marrow fibroblast growth factor-1 ( FGF-1) in chronic aplastic anemia ( CAA) patients. Methods Sixty cases of CAA were randomly divided into treatment group and control group, 30 cases in each group. Both groups were given conventional western medicine such as oral use of Stanozolol and Ciclosporin, and additionally, the treatment group received oral use of MBD. Six months constituted one treatment course for both groups. After treatment, the clinical efficiency in western medicine field and on Chinese medical syndromes was evaluated in both groups. The changes of peripheral hemogram, adverse reaction, and FGF-1 in the bone marrow of both groups were also monitored. Results ( 1) Clinical efficacy in western medicine field was 80.0% in the treatment group, and was 66.7%in the control group (P<0.05). (2) The total effective rate on Chinese medical syndromes was 100.0% in the treatment group, and was 83.3%in the control group (P<0.05). (3) After treatment, the scores of symptoms were decreased in both groups (P<0.05 or P<0.01 compared with those before treatment), and the decrease in the treatment group was superior to that in the control group (P<0.05). (4) Peripheral white blood cell (WBC) count, hemoglobin (HGB) content and platelet (PLT) count as well as bone marrow FGF-1 were increased in both groups after treatment (P<0.01 compared with those before treatment), and the increase of WBC, HGB, PLT and FGF-1 in the treatment group was superior to that in the control group (P<0.05). (5) In the aspect of the adverse reaction, the treatment group had 2 cases of hepatic fucntion injury, and one case of acne and hairiness; the control group had 2 cases of gum hypertrophy, 5 cases of hepatic function injury, and 4 cases of acne and hairiness. The control group had higher incidence of adverse reaction ( P<0.05). Conclusion MBD exerts certain therapeutic effect for CAA, and one of the possible mechanisms is related with the regulation of FGF-1 level.

Aim To study the inhibitory and apoptosis-inducing effects of aspisol on proliferation of B16 melanoma in vitro and in vivo. Methods The effect of aspisol on the proliferation of B16 cells was analyzed by MTT assay; its effect on cell apoptosis was measured by flow cytometry. The suspension of melanoma cells was injected subcutaneously into forelimb axillas of C57BL/6J mice to establish xenograft models. From the next day, the mice received intraperitoneal injection of aspisol in different concentrations once a day for 28 days; the mice received injection of dacarbazine (DTIC) were used as positive controls,and received injection of normal saline (NS) were used as negative controls. The inhibition rate of tumor growth was calculated .The apoptosis rate was detected by TUNEL assay. The expression of Survivin and C-erbB-2 was detected by immunohistochemistry. Results Aspisol inhibited the proliferation of B16 cells, with the inhibition rate up to (68.78?1.27)%, and induced the apoptosis with the highest apoptosis rate up to 15.8%.The inhibition rate of tumor growth was 15.0% in 200 mg?kg-1 aspisol group, 32.3% in 400 mg?kg-1 aspisol group, 49.4% in 800 mg?kg-1 aspisol group,and 51.4% in 40 mg?kg-1 DTIC group. Typical apoptotic morphologic changes were seen in the 4 groups. Survivin and C-erbB-2 expression was significantly lower in aspisol groups than in NS group. Conclusion Aspisol could inhibit proliferation and induce apoptosis of B16 melanoma cells in vitro and in vivo, which may be correlated to down-regulation of Survivin and C-erbB-2.

Objective:To compare clinical effects of the open versus closed high tibial osteotomy on knee osteoarthritis.Methods:A total of 100 patients with knee osteoarthritis admitted to our hospital from May 2018 to May 2019 were included.They were randomly divided into groups A and B(n=50, each group)according to the principle of random and double blind.Patients in group A received the medial opening high tibial osteotomy, and group B were treated with lateral closed high tibial osteotomy.The changes in the Lysholm knee score, hospital for special surgery(HSS)knee score and complications were compared between the two groups before and 1 year after surgery.The correction angle, the change of patella height before and after operation, and the change of posterior slope of tibial plateau were compared between the two groups.Results:Before and after treatment, Lysholm scores were(63.51±5.47)and(90.98±5.84)( t=24.275, P=0.000), and HSS scores were(51.85±4.68)and(88.64±5.87)( t=34.652, P=0.000). Lysholm scores were(62.98±6.14)and(91.52±6.54 9)( t=22.497, P=0.000), and HSS scores were(52.05±5.16)and(89.54±5.15)( t=36.362, P=0.000)in group A and B, .After treatment, all index were significantly improved in the two groups, but there was no statistical difference between the two groups( P>0.05). In group A, the posterior slope of tibial plateau were(8.75±1.48)° and(10.25±1.65)°( t=4.785, P=0.000)and the patellar height was(0.890±0.031)and(0.898±0.032)( t=1.270, P=0.207)before and after treatment.Before and after treatment in group B, the posterior slope of tibial plateau were(8.69±1.53)° and(5.26±1.21)°( t=12.434, P=0.000)and the patellar height were(0.889±0.047)and(0.821±0.039)( t=7.873, P=0.000). The correction angle, posterior slope of tibial plateau and patella height were significantly improved after treatment in the two groups.While, the decreases of posterior slope of tibial plateau and patella height were better in the group B than in the group A( P<0.05). There was no significant difference in the incidence of complications between the two groups( P>0.05). Conclusions:For treatment of knee osteoarthritis patients, the medial opening high tibial osteotomy and lateral closed high tibial osteotomy have the same exact effect and high safety, but the two methods have their own advantages and disadvantages in clinical treatment.And the appropriate surgical treatment can be selected according to the characteristics of patients.

Objective To observe clinical efficacy of warm-promotion needling for the treatment of cold coagulation and blood stasis of primary dysmenorrhea.Methods Totally 120 patients with cold coagulation and blood stasis of primary dysmenorrhea were randomly divided into warm-promotion needling group (60 cases) and control group (60 cases). Warm-promotion needling group was treated with warm-promotion needling at Guanyuan (RN4), Sanyinjiao (SP6), Shiqizhui (EX-B8), and Diji (SP8), and cooperated with Ciliao (BL32), Hegu (LI4), and Taichong (LR3). Control group took same acupoints and applied uniform reforcing-reducing method. The two groups began treatment 5-7 d before menstruation, 1 times a day, for 7 times. The treatment was given 3 menstrual cycles. The visual analogue scale (VAS) and COX menstrual symptom scale (CMSS) were used to observe the pain degree at the end of 1, 2, 3 menstrual cycles. The clinical efficacy was evaluated 3 months after treatment.Results The scores of VAS and CMSS was obviously reduced in the two groups after the treatment compared with those before treatment (P<0.01). The synperiodic scores of VAS and CMSS in warm-promotion needling group was obviously lower than those in the control group (P<0.05). The total effective rate of warm-promotion needling group was 96.67% (58/60), and the control group was 73.33% (44/60), the difference was significant (P<0.05).Conclusion Warm- promotion needling can obviously relieve dysmenorrhea symptoms and shorten the time of pain of patients with cold coagulation and blood stasis of primary dysmenorrhea, which has affirmative clinical efficacy.

Objective To analyze the correlation between white matter injury and cognitive dysfunction using diffusion tensor imaging (DTI).Methods Seventeen subjects with TBI hospitalized from October 2012 to September 2013 had Glasgow coma scale (GCS) score of ≥ 13 (mild injury group, 10 cases) and ≤ 12 (moderate-severe injury group, 7 cases).Another 17 healthy subjects were used as controls.All were submitted to DTI examination.Fractional anisotropy (FA) and apparent diffusion coefficient(ADC) values in genu corpus callosum, splenium corpus callosum, posterior internal capsule, anterior internal capsule, and cerebral peduncle were calculated using the Neuro 3D software.Correlations between FA and ADC with the mini-mental state examination (MMSE) score were evaluated.Results Moderate-severe injury group demonstrated significantly reduced FA values in genu corpus callosum and splenium corpus callosum, and significantly increased ADC values of genu corpus callosum, splenium corpus callosum, posterior internal capsule and cerebral peduncle when compared to control group (P ＜0.05 or 0.01).FA and ADC values in the regions of interest did not differ significantly between mild injury group and control group (P ＞ 0.05).In the genu corpus callosum and splenium corpus callosum, FA values were positively correlated with MMSE score (r =0.636, 0.601), while ADC values were negatively correlated with MMSE score (r =0.552, 0.660).Conclusions DTI reveals the cerebral white matter lesion that is undetectable using CT and conventional MRI.DTI is a helpful tool to evaluate the degree of cognitive function in patients with TBI, which provides the basic reference for the clinical treatment and prognosis.

Objective To systematically assess the effectiveness and safety of acupuncture and moxibustion for treatment of rheumatoid arthritis. Methods Articles were searched from databases, i.e., CNKI, VIP, WanFang Data, CBM, Embase, and PubMed. Articles about RCT on acupuncture and moxibustion for rheumatoid arthritis and traditional medicine therapy were under meta-analysis. Results Totally 24 articles involving 2006 patients were included. The results of meta-analysis indicated that the overall effective rate of treatment in the group receiving acupuncture and moxibustion was higher than that in the drug group, with statistical significance [OR=2.73, 95%CI (2.18, 3.41), Z=8.78, P<0.000 01]. Sub-group analysis showed that:acupuncture and moxibustion showed statistical significance in decreasing serum RF levels compared with drug therapy [MD=-2.92, 95%CI (-5.60, -0.25), P<0.05]. Acupuncture and moxibustion showed statistical significance in decreasing serum ESR levels compared with drug therapy [MD=-2.99, 95%CI (-4.78, -1.21), P<0.05]. Acupuncture and moxibustion showed statistical significance in decreasing serum CPR levels compared with drug therapy [MD=-1.44, 95%CI (-2.44, -0.44), P <0.05]. Conclusion The overall effective rates of acupuncture and moxibustion for rheumatoid arthritis and the decreasing levels of RF, ESR, CRP are superior to drug therapy, but it still needs larger samples, multi-center, and high quality RCT to verify.

Poly(ADP-ribose) polymerase-1 (PARP-1) has emerged as a promising anticancer drug target due to its key role in the DNA repair process. It can polymerize ADP-ribose units on its substrate proteins which are involved in the regulation of DNA repair. In this work, a novel series of para-substituted 1-benzyl-quinazoline-2, 4 (1H, 3H)-diones was designed and synthesized, and the inhibitory activities against PARP-1 of compounds 7a-7e, 8a-8f, 9a-9c and 10a-10c were evaluated. Of all the tested compounds, nine compounds displayed inhibitory activities with IC50 values ranging from 4.6 to 39.2 micromol x L(-1). In order to predict the binding modes of the potent molecules, molecular docking was performed using CDOCKER algorithm, and that will facilitate to further develop more potent PARP-1 inhibitors with a quinazolinedione scaffold.

PARP [poly(ADP-ribose)polymerase] represents a novel potential target in cancer therapy. It is involved in a DNA repair process by catalyzing the transfer of ADP-ribose units from NAD to a number of its substrate proteins. In this work, a series of novel azaindole derivatives was designed and synthesized. Moreover, 16 target molecules were screened and 8 compounds displayed inhibitory activity against PARP-1. It has been demonstrated that these azaindoles bearing cycloamine substituents at 2-position were active to both PARP-1 and PARP-2.
