The research and quality control of traditional Chinese medicine has meaningful importance, because it has influence not only in the health and treatment of patients, but also in the solid growth and development of phar-maceuticals companies. In some cases, for the complex of TCM, the common QC method on single or multi-target compounds can't really and truly disclose the quality of the Chinese materia medica. Therefore, a lot of researchers do plenty of works to make clear the effectiveness basis, to improve the quality and realize the modernization of TCM. All of these works close together with modern analysis and separation technology. In this article, a novel analy-sis technology-UltraPerformance Convergence Chromatography (UPC2) based its characters and applications should be introduced. It should be a helpful technology for the TCM researchers to facilitate the study and QC works.

Objective To evaluate the incidence of net adverse clinical and cerebral events (NACCE) 1 year after implantation of biodegradable polymer stents (BP-SES) in elderly patients with coronary artery disease.Methods The clinical data of patients inserted with BP-SES in I-LOVE-IT 2 Trial were retrospectively analyzed, including 1829 elderly patients admitted in the General Hospital of Shenyang Military Command from Oct. 2012 to Jun. 2013, of which 62 cases aged equal to and more than 65 years (elderly group) and 1202 cases less than 65 years (non-elderly group). The primary end-point of this research was target lesion failure (TLF) rate on 12 months and the secondary end-point was the incidence of NACCE, including all-cause death, all myocardial infarction, stroke and severe hemorrhage (BARC type ≥3), and then the multiple regression analysis was performed.Results The Baseline conditions of the two groups were significantly different (P<0.05) including BMI, diabetes, hypertension, hyperlipidemia, family history of coronary heart disease, smoking history, past stroke history, history of peripheral vascular disease and stable angina pectoris. When comparing elderly group with non-elderly group, marked differences existed on the incidence of NACCE (10.0%vs. 5.2%,P<0.01), all-cause mortality (2.7%vs. 0.7%,P<0.01), myocardial infarction (5.6%vs. 3.5%,P=0.03), stent thrombosis (1.9%vs. 0.5%,P<0.01) and stroke (2.2%vs. 0.8%,P=0.01). Multiple regression analysis revealed that elderly (age ≥65) was the independent predictive factor for NACCE (OR=1.904, 95%CI 1.304-2.781,P=0.001).ConclusionThe incidence of NACCE is increased significantly in elderly patients (age ≥65), and elderly is an independent predictive factors for 12-month NACCE in patients implanted with BP-SES

Objective To evaluate the stability of the pelvic ring reconstruction using fibular autograft for periacetabular tumor type Ⅱ resection. Methods 6 adult cadaveric specimens were tested. The periacetabular tumor resection models were established according to Ennecking's type Ⅱ resection. The resected pelvic rings were reconstructed with double-fibular graft fixed by four internal fixation techniques including plates, pedicle-rods (PR), lateral-rods (LR) or sacral-iliac rods (SIR). Axial loading from the proximal L3 vertebral body was applied by MTS load cell in the gradient of 0～500 N in the double feet standing state. Images in front view were obtained using CCD camera. Based on Image J software, displacement of the first sacral vertebrae （S1） of the reconstructed pelvis and intact pelvis were calculated using digital maker tracing method with center-of-mass algorithm. Results The rotational movements and vertical displacement of S1 around the normal side femoral head of the reconstructed pelvis in coronary plane were found in simulated bilateral leg standing position. The average vertical load-displacement and load-angular rotation curve of S1 in coronary plane were approximately linear behavior under the vertical load 500 N. The average vertical displacement and angle of S1 in coronary plane had not overacted. The stability of axial direction and rotation had not changed significantly when reconstructed by LR or Plates compared with the intact pelvis, but the SIR did. Conclusion Plates and LR fixation were more stabile for periacetabular tumor type Ⅱ resection.

Objective To observe dynamic variation of neural precursor cells in dentate gyrus of hippocampus and effect of Yangxue Qingnao Granule on it in vascular dementia rats. Methods 72 Sprague-Dawley rats were randomly divided into sham group (n=24), vascular dementia group (model group, n=24) and Yangxue Qingnao Granule group (treatment group, n=24). The vascular dementia model was established with modified Pulsineli's four-vessel occlusion. The expression of Nestin was detected with Western blotting, the expression of 5-bromodeoxyuridine (BrdU) and BrdU/Nestin were detected with immunofluorescence in dentate gyrus of hippocampus 1, 2, 4 and 8 weeks after modeling. Results The expression of Nestin, BrdU and BrdU/Nestin increased in the model and treatment groups with time, peaked at 4 weeks after modeling, and it was more than that of the sham group on all the time points (P<0.01). However, it was more in the treatment group than in the model group on all the time points (P<0.01). Conclusion Yangxue Qingnao Granule promotes the proliferation of neural precursor cells in dentate gyrus of hippocampus in vascular dementia rats.

OBJECTIVETo observe the law of the meridian abnormal changes and the correlation with acupuncture efficacy based on the effectiveness study of electroacupuncture (EA) in treatment of severe functional constipation.

METHODSSeventy patients of severe functional constipation were randomized into an EA group and a sham-EA group, 35 cases in each one. In the EA group, Tianshu (ST 25) and Fujie (SP 14) were punctured deeply and stimulated with EA (dense-disperse wave, 2Hz/15 Hz, 0. 1 to 1. 0 mA), and Shangjuxu (ST 37) was needled. In the sham-EA group, the sites lateral to Tianshu (ST 25) and Fujie (SP 14) were punctured shallowly and stimulated with electricity. The site lateral to Shangjuxu (ST 37) was punctured shallowly. The treatment was given continuously for 8 weeks in the two groups, 5 times weekly in the first 2 weeks and 3 times weekly in the rest 6 weeks. WANG Juyi's meridian examination method was applied to detect the abnormalities of the spleen, stomach and large intestine meridians before treatment, and in 2, 4, 6 and 8 weeks among 70 patients separately. The frequency of complete spontaneous bowel movement (CSBM) every two weeks, meridian abnormal value and the relativity with CSBM change rate were compared in the patients between two groups.

RESULTSRegarding the increase of CSBM frequency, the effect started since the 2nd week in the EA group, with the treatment going on, CSBM frequency was increased apparently (all P<0. 05). In the sham-EA group, after 6 and 8-weeks of treatment, CSBM frequency was increased apparently as compared with that before treatment (all P<0. 05). The increase of CSBM frequency in the EA group was remarkably as compared with the sham-EA group at every time point (all P<0. 05). The abnormal value of the large intestine meridian in 2 weeks of treatment and the values of the stomach and spleen meridians and the relevant meridians in 4 weeks of treatment were all reduced apparently as compared with those in the baseline in the EA group (all P<0. 05). With the treatment time going on, the abnormal reflections on the large intestine and stomach meridians were reduced gradually (all P<0. 05), and the total change rate of abnormalities on the large intestine, stomach and spleen meridians presented the negative correlation with the total change rate of CSBM frequency (P<0. 01, P<0. 05).

CONCLUSIONIn the EA group, the efficacy on CSBM frequency in severe functional constipation is advantageous and stable as compared with the sham-EA group. Acupuncture at the relevant acupoints of the spleen, stomach and large intestine meridians achieves the definite regulation to the meridian abnormalities. It is discovered that the abnormal changes in the spleen, stomach

OBJECTIVETo summarize the clinical features, biochemical change and genetic mutations of a neonate with congenital bile acid synthesis disorder type 2.

METHODSClinical features, blood biochemical index, gene analysis and treatment of the patient were reviewed.

RESULTSThe patient presented with the symptoms of jaundice 3 days after birth but without skin itching. Pale stool was noted. Subsequently, he presented with hepatomegaly, blood coagulation disorders, left cochlear nerve damage, liver cirrhosis and remarkable growth retardation. Serum biochemistries showed that bilirubin and transaminase were elevated, while γ -GT and total bile acid was normal. Abdominal ultrasonography indicated decline of gallbladder contraction. Cholangiography showed normal extra- and intrahepatic bile ducts and patent biliary tract. Liver biopsy showed intrahepatic cholestasis. Gene testing has identified a homozygous mutation in AKR1D1 gene.

CONCLUSIONCongenital bile acid synthesis disorder should be suspected when a neonate has presented with jaundice, elevated bilirubin and transaminase, normal or reduced TBA and γ -GT. Genetic testing and urine mass spectrometry analysis can diagnose congenital bile acid synthesis disorder. Early therapy is crucial to patients with congenital bile acid synthesis disorder.

Objective To investigate the effect of shortening the hemodialysis patients′waiting time for treatment on improving the medical condition. Methods A total of 294 hemodialysis patients in our dialysis center were randomly enrolled in the study from January to June, 2013. The patients, enrolled from January to March, received traditional method ( n=150 ) , and the patients, enrolled from April to June received quality control circle method (n=144), using of the method of slip the peak waiting time for treatment. The application of quality control circle was applied in patients′ waiting, pre-diagnosis, on-line and other medical aspect of continuous quality. The time and satisfaction were compared. Results Three months after the intervention, the waiting time of patients shortened 11 minutes compared with before. The satisfaction of patients improved from 80. 00% to 94. 40% in the pre-diagnosis in order, and the difference was statistically significant (χ2 =13. 792, P<0. 05). Conclusions The implementation of slip the peak waiting time for treatment shortened patients′waiting time and make the pre-diagnosis in order. It can not only reduces the incidence of cross infection, but enhance the concept of nursing care-fair and reasonable. Patients satisfaction on nursing work is also significantly improved, so it effectively avoid the accidental events.

Objective To analyze the prognostic impact of Ikaros family zinc finger 1(IKZF1)mutation on adult Philadelphia chromosome (Ph1) positive acute lymphoblastic leukemia (ALL) patients.Methods IKZF1 mutation was detected in 63 adult Phi positive ALL patients at diagnosis using capillary electrophoresis.Recruited patients were treated in our center and other three hospitals in Ningbo from January 2014 to January 2017.Clinical data were collected and retrospectively analyzed.Results Thirty-nine (61.9％) patients were positive IKZF1 mutation in this cohort.The white blood cell (WBC) count in IKZF1 mutation group was significantly higher than that of mutation negative group [(64.6±11.3)× 109/L vs.(33.7±5.6)×109/L,P＜0.05].Patients with WBC count over 30×109/L accounted for 56.4％ in IKZF1 mutation group.Complete remission (CR) rate in the IKZF1 mutation group was also lower than that of negative group after induction chemotherapy (64.1％ vs.75.0％,P＞0.05).IKZF1 was a negative prognostic factor but not independent factor for survival by univariate and multivariate analyses.Patients were divided into chemotherapy and allogeneic transplantation groups.The 3-year overall survival (OS) rate and 3-year leukemia-free survival (LFS) rate in IKZF1 mutation group were significantly lower than those of negative group in both transplantation group (42.3％ vs.59.3％;31.2％ vs.50.0％;respectively,both P＜0.05) and chemotherapy group (24.8％ vs.40.0％;19.0％ vs.34.3％;respectively,both P＜0.05).Conclusion IKZF1 mutation is a poor prognostic factor for adult Ph1 positive ALL patients.
