A complete framework of acupuncture reinforcement-reduction manipulations in Neijing was outlined to reflect the features according to the train of thought from purpose, principle, judgement, manipulation and curative effect through the analysis on the records of acupuncture reinforcement-reduction manipulations in Neijing. The result of the research showed that the basic purpose of reinforcement-reduction manipulations was the regulation of qi, and the core connotation was the regulation of the mind in Neijing. The key points included reinforcing deficiency before reducing excess and reinforcement or reduction manipulated according to 25 types of constitutions, pulse changes and skin conditions based on the general principle of reinforcing deficiency and reducing excess. Neijing recorded 7 kinds of acupuncture reinforcement-reduction manipulations and influenced their development in later age, which put the attention to the changes and regulation of the spirit, mind and mindwill. The feeling of patient and changes of pulse and skin temperature were taken as the review criterion of curative effect.

Objective To explore the pharmacokinetics of single and multiple oral 20 mg escitalopram in healthy Chinese volunteers. Methods A total of 12 subjects participated in the study. Escitalopram 20 mg was given orally once on day 1 and days 8 to 14 in the fast condition.

OBJECTIVETo observe the X-ray features of bone damage in patients with moderate endemic skeletal fluorosis and the changes of X-ray after treatment with herbal therapy.

METHODSFrom 2007.12 to 2009.8,114 patients with moderate endemic skeletal fluorosis were randomly divided into treatment group and control group by central randomization system. There were 60 patients in treatment group including 26 males and 34 females,aged from 39 to 60 years with an average of (51.68 +/- 4.98) years; There were 54 patients in control group included 30 males and 24 females, aged from 39 to 60 years with an average of (52.15 +/- 4.86) years. Both treatment and control groups were treated with basic treatment including calcium supplementation and preparation stage with herb decoction. Patients were orally given 600 mg Caltrate everyday for calcium suptrointestinal function and promoting the digestion and absorption of herb decoction for 3 days. Patients in treatment group were rally given Guo's Maqian decoction(200 ml,twice daily) for 8 weeks. Eight weeks later,Guo 's Maqian decoction was replaced y Guokangning capsule (0.44 g per cansule,2 capsules,three times daily) for 4 weeks. The treatment course lasted 12 weeks. The time for followed-up after treatment was 24 weeks. When the treatment finished, 7 experts on orthopaedics and radiology evaluated and statistically analyzed the X-ray features pre and post treatment,using expert evaluation scale (including the appearance and changes of osteosclerosis,osteoporosis softening,joint changes close to the bone and mixed changes) designed referring endemic skeletal fluorosis X-ray findings and sub-degree standard(WS192-2008).

RESULTSAll X-ray features of endemic skeletal fluorosis appeared in the X-ray of the 114 patients with moderate endemic skeletal fluorosis. Osteosclerosis: 4 cases in forearm, 7 in calf,4 in pelvis,4 in lumbar vertebrae ;Osteoporosis and bone softening: 23 cases in forearm patients, 23 in calf, 5 in pelvis, 8 in lumbar vertebrae; Mixed changes: 6 cases in forearm, 9 in calf, 10 in pelvis, 1 in lumbar vertebrae patients; oint changes: 107 cases in forearm, 47 in calf, 28 in pelvis, 19 in lumbar vertebrae. There were X-ray no changes before and after the treatment in all of parts in control group. In treatment group, there were only 2 patients showed extraperiostealin and joint changes after the treatment, in which one showed better ossification of interosseous membrane of leg and another one showed disappearance of the lateral hyperplasia of the left pelvic acetabulum. There were no changes between before and after treatment in X-ray of all parts in the rest patiens of the treatment group. There was no significant difference between before and after treatment in both groups (P > 0.05).

CONCLUSIONThere is no obvious improvement in radiology of patients with skeletal fluorosis treated by Guo's therapy.

The objective was designed to assess the clinical efficiency of preventing febrile nonhemolytic transfusion reactions (FNHTR) with transfusion of leukocyte-depleted RBC and platelet concentrates. One hundred patients with cirrhosis of liver, gastric ulcer and cancer were selected to receive RBC concentrates with leukocyte filtration. Another group of 50 patients with liver necrosis, gastric ulcer and cancer were selected to receive non-filtered RBC concentrates. Two hundred and forty patients with acute or chronic leukemia, aplastic anemia, multiple myeloma, thrombocytopenia purpura, diabetes mellitus, cirrhosis of liver, upper gastrointestinal hemorrhage, severe hepatitis, burn and cancer post radioactive or chemical treatment were divided into two group with 120 patients in each one and selected randomly to receive platelet concentrates. The incidence rates of FNHTR in all patients were investigated. Results showed that there was no FNHTR in 100 transfusions with leukocyte-depleted RBC concentrates. Eight out of 50 patients with non-filtrated RBC concentrates showed FNHTR. The incidence of FNHTR was sixteen (16%) in non-filtrated transfusion. Twenty-five and 7 patients manifested FNHTR respectively in non-filtrated or filtrated platelets transfusions. The incidence of FNHTR was 20.83% and 5.83% respectively in non-filtrated or filtrated platelet transfusion. It is concluded that leukocyte-depleted RBC and platelet concentrates reduces FNH TR in blood transfusion.

BACKGROUNDStudies have suggested that use of prolonged dual antiplatelet therapy (DAPT) following new generation drug-eluting stent implantation may increase costs and potential bleeding events. This study aimed to investigate the association of DAPT status with clinical safety in patients undergoing everolimus-eluting stent (EES) implantation in the SEEDS study (A Registry to Evaluate Safety and Effectiveness of Everolimus Drug-eluting Stent for Coronary Revascularization) at 2-year follow-up.

METHODSThe SEEDS study is a prospective, multicenter study, where patients (n = 1900) with small vessel, long lesion, or multi-vessel diseases underwent EES implantation. Detailed DAPT status was collected at baseline, 6-month, 1- and 2-year. DAPT interruption was defined as any interruption of aspirin and/or clopidogrel more than 14 days. The net adverse clinical events (NACE, a composite endpoint of all-cause death, all myocardial infarction (MI), stroke, definite/probable stent thrombosis (ST), and major bleeding (Bleeding Academic Research Consortium II-V)) were investigated according to the DAPT status at 2-year follow-up.

RESULTSDAPT was used in 97.8% of patients at 6 months, 69.5% at 12 months and 35.4% at 2 years. It was observed that the incidence of NACE was low (8.1%) at 2 years follow-up, especially its components of all-cause death (0.9%), stroke (1.1%), and definite/probable ST (0.7%). DAPT was not an independent predictor of composite endpoint of all-cause death/MI/stroke (hazard ratio [HR]: 0.693, 95% confidence interval [CI]: 0.096-4.980, P = 0.715) and NACE (HR: 1.041, 95% CI: 0.145-7.454, P = 0.968). Of 73 patients who had DAPT interruption, no patient had ST at 12-month, and only 1 patient experienced ST between 1- and 2-year (1.4%). There was a high frequency of major bleeding events (53/65, 82.5%) occurred in patients receiving DAPT treatment.

CONCLUSIONSProlonged DAPT use was not associated with improved clinical safety. The study emphasized that duration of DAPT needs to be shortened in Chinese patients following EES implantation (ClinicalTrials.gov identifier: NCT 01157455).

OBJECTIVETo develop a high-throughput screening assay for Farnesoid X receptor (FXR) agonists based on mammalian one-hybrid system (a chimera receptor gene system) for the purpose of identifying new lead compounds for dyslipidaemia drug from the chemical library.

METHODScDNA encoding the human FXR ligand binding domain (LBD) was amplified by RT-PCR from a human liver total mRNA and fused to the DNA binding domain (DBD) of yeast GAL4 of pBIND to construct a GAL4-FXR (LBD) chimera expression plasmid. Five copies of the GAL4 DNA binding site were synthesized and inserted into upstream of the SV40 promoter of pGL3-promoter vector to construct a reporter plasmid pG5-SV40 Luc. The assay was developed by transient co-transfection with pG5-SV40 Luc reporter plasmid and pBIND-FXR-LBD (189-472) chimera expression plasmid.

RESULTSAfter optimization, CDCA, a FXR natural agonist, could induce expression of the luciferase gene in a dose-dependent manner, and had a signal/noise ratio of 10 and Z' factor value of 0.65.

CONCLUSIONA stable and sensitive cell-based high-throughput screening model can be used in high-throughput screening for FXR agonists from the synthetic and natural compound library.

OBJECTIVETo investigate clinical and laboratory characteristics of acute myeloid leukemia (AML) patients with t(7;11)(p15;p15).

METHODSEleven patients with t(7;11)(p15;p15) were retrospectively reviewed involved in cell morphology, immunophenotype, cytogenetics as well as clinical features and prognosis.

RESULTSEight patients out of the eleven were female, six patients were AML-M2a, two M4, two M5, and one M6. All the 11 cases expressed CD33, 10 expressed CD117 and CD13, HLA-DR and CD34 was expressed in 7 and 6 patients, respectively. Karyotypes of all the patients were t(7;11) (p115;p15), additional trisomy 8 were found in only one patient. FLT3-ITD was positive in one of nine patients who were analysed for FLT3-ITD and FLT3-TKD. Two patients were alive, and one lost to followed up, while the rest of eight were dead.

CONCLUSIONThe t(7;11) (p15;p15) abnormalities is one of rare chromosomal translocation in patients with AML. AML patients with t(7;11) (p15;p15) have clinical features of anemia, thrombocytopenia, higher white blood cell, and poor prognosis.

BACKGROUNDNumerous studies have investigated the influence of osseous factors on patellofemoral joint instability, but research on the influence of dynamic muscle factors in vivo is still in the exploratory stage. This study aimed to use magnetic resonance imaging (MRI) and diffusion tensor imaging (DTI) to evaluate vastus medialis oblique (VMO) fiber bundles in patients with recurrent patellar dislocation to explore the changes in muscle morphology and function.

METHODSThis prospective study involved 30 patients (7 males and 23 females; average age, 21.4 ± 3.8 years) clinically diagnosed with recurrent patellar dislocation in Peking University Third Hospital and 30 healthy volunteers matched for age, sex, and body mass index in our medical school between January 2014 and October 2014. None of the patients had a recent history of traumatic patellar dislocation or transient patellar dislocation. All patients underwent conventional MRI and DTI of the knee. The cross-sectional area of the VMO on MRI and the fractional anisotropy (FA), apparent diffusion coefficient (ADC), and primary (λ1), secondary (λ2), and three-level characteristic (λ3) values on DTI were measured. The independent-samples t-test was used to compare these parameters between the two groups.

RESULTSCompared with the control group, the patient group showed significantly higher FA values (0.39 ± 0.05 vs. 0.33 ± 0.03) and significantly lower ADC (1.51 ± 0.13 vs. 1.58 ± 0.07), λ2 (4.96 ± 0.13 vs. 5.04 ± 0.07), and λ3 values (4.44 ± 0.14 vs. 4.58 ± 0.07; t = 5.99, t = -2.58, t = -3.02, and t = -4.88, respectively; all P < 0.05). Cross-sectional VMO area and λ1 values did not differ between the two groups (t = -1.82 and t = 0.22, respectively; both P > 0.05).

CONCLUSIONSThe functional status of the VMO is closely associated with recurrent patellar dislocation. MRI, especially DTI (FA, ADC, λ2, and λ3), can detect early changes in VMO function and might facilitate the noninvasive monitoring of the functional status of the VMO in patients with recurrent patellar dislocation.

OBJECTIVETo study the effect of Shenfu Injection (SF) on the apoptosis of prostate cancer PC-3 cells and its possible mechanism.

METHODSWe divided prostate cancer PC-3 cells into a blank control group and three experimental groups, the latter treated with SF at 50, 100, and 200 microl/ml, respectively, for 24, 48, and 72 hours. Then we determined the proliferation of the cells by MTT assay, measured their apoptosis by Annexin V/PI flow cytometry, and detected the expression of P53 mRNA by RT-qPCR.

RESULTSCompared with the blank control group, the survival rates of the prostate cancer PC-3 cells in the 50, 100, and 200 microl/ml SF groups were (93.76 +/- 2.63)%, (81.21 +/- 1.80)% and (18.01 +/- 3.84)% at 24 hours, (94.67 +/-1.11)%, (78.33 +/- 2.89)% and (10.34 +/- 1.44)% at48 hours, and (91.30 +/- 0.47)%, (36.67 +/- 1.56)% and (1.33 +/- 0.32)% at 72 hours, all significantly increased in a dose- and time-dependent manner (P < 0.05). The expression of p53 mRNA was also markedly increased in all the three experimental groups at 48 hours (P < 0. 05).

CONCLUSIONSF can inhibit the proliferation and induce the apoptosis of PC-3 cells, which may due to its upregulation of the p53 mRNA expression.
