Methods The HPLC system consisted of the Fortis-C18 (4.6 mm × 250 mm, 5μm) column, the mobile phase consisted of HCN∶H2O (12∶88) , the flow rate was 1.0 ml/min, the column temperature was 30℃, The UV detector was set at 238 nm. Results The linear response range was 0.049~0.980mg/ml ( r=0.999 9). The average recovery of geniposide was 99.1%, and RSD was 1.66%. Conclusion The method is simple, rapid, accurate and repeatable. It can be applied in determination of Geniposide in Diaojinyao Powder.

Objective To study 3D imaging and pelvic angiography for multiple pelvic fracture. Methods 30 cases suspected with multiple pelvic fracture with vascular injury were performed with 3D imaging and pelvic angiography, whose dada were analyzed retrospectively. Results 30 cases had multiple pelvic fracture to different extents, of which 25 ones had no abnormality at lower part of abdominal aorta, left & right common iliac artery, left & right iliac artery, external iliac artery and upper part of left & right femoral artery, and 1 case, complicated with local hematoma, had a raptured left external iliac artery at the middle piece of the ilium, and another two cases, also complicated with local hematoma, had a raptured left iliac artery due to the comminuted fracture of the sacrum and a raptured right anterior femoral artery due to the fracture of light femur respectively. Conclusion 16-slice CT has to be involved in when the patient with multiple pelvic fracture is suspected with vasculaer injury.

Cholangiolocellular carcinoma (CLC) is a rare type of primary liver cancer,which is thought to originate from hepatic progenitor cells.CLC is categorized as a different tumor type from the conventional intrahepatic cholangiocarcinoma (cICC) due to its unique histological and embryological features.This review summarizes the clinical,radiological and pathological characteristics and surgical outcomes of cICC and CLC.This pathological classification may provide important clinical implications for the treatment and outcome evaluation of this disease.

Objective To observe the clinical efficacy of acupuncture-moxibustion in treating postsurgical gastroparesis syndrome (PGS) and the effect on gastrin (GAS) and motilin (MTL).Method Fifty PGS patients were randomized into a treatment group and a control group, 25 cases in each group. The control group was intervened by conventional medication, including effective gastrointestinal decompression, nutrition support, and psychotherapy; the treatment group was by acupuncture-moxibustion therapy in addition to the intervention given to the control group. The time of restoring gastric motility, the distention and fullness grading score, and serum GAS and MTL levels were observed, and the clinical efficacies were also compared.Result The total effective rate was 100.0% in the treatment group versus 92.0% in the control group, and the between-group difference was statistically insignificant (P>0.05). According to statistical analysis, there was a significant difference in comparing the time of restoring gastric motility between the two groups (P<0.01). The distention and fullness grading scores, GAS and MTL levels were significantly changed after intervention in both groups (P<0.01). The distention and fullness grading score, GAS and MTL levels of the treatment group were significantly different from that of the control group after intervention (P<0.01).Conclusion Acupuncture- moxibustion plus medication is an effective approach in treating PGS, and it can up-regulate the GAS and MTL levels.

The mature seeds and excised embryos of Dalbergia odorifera were used as materials to study the effect of moisture content on their survival, as well as the effect of rapid freezing and vitrification freezing method on seeds and in vitro embryos cryopreservation. The results showed that the germination rate and vigor decreased from 82.67%, 85% to 18.35%, 25% respectively, when the seed moisture content decreased from 15.04% to 8.14%; and the germination rate decreased from 82.67% to 37.50%, 25.37% respectively by vitrification freezing method and rapid freezing method, when the seed moisture content decreased from 15.04% to 9.37%. Among all the moisture content gradient, 12.35% moisture reached the maximal germination rate, which were 63.58% and 50.45% respectively by vitrification freezing and rapid freezing; and when the embryo moisture content was 26.32%, the germination rate decreased from 95.67% to 58.31% and 33.82% respectively by vitrification freezing and rapid freezing. And when the moisture content was in the range of 14.17% -21.34%, the germination rate was a bit of decrease. The experiment results showed that the optimum conditions of seed cryopreservation were: moisture content 12.35%, vitrification freezing; and the optimum conditions of in vitro embryo cryopreservation were: moisture 15.04%, vitrification freezing. In conclusion, the effects of moisture content on germination rate after cryopreservation in D. odorifera seeds and embryo were significant, and vitrification freezing method is much better than rapid freezing method.

Objective To evaluate the efficacy and safety for cervical ripening by double-balloon catheter among full-term pregnancy women underwent labor induction.Methods It was a prospective nonrandomly controlled research.Totally 128 singleton-pregnancy women in full-term who had to undergo labor induction because of pregnancy complications or comorbidities from August 2011 to April 2013 in Peking University First Hospital were selected as study subjects.Participants were allocated to preinduction cervical ripening with either a double-balloon catheter (66 participants,study group) or prostaglandin vaginal insert (62 participants,control group).Compare the efficacy for cervical ripening and adverse reactions between the two groups.Results The efficacy for cervical ripening (Bishop scores improved by ≥ 2) had no significant differences between study and control groups [82％ (54/66) compared with 81％ (50/ 62),P＞0.05].The time interval between intervention and parturiency was significantly higher in the doubleballoon catheter group than in the prostaglandin vaginal insert group [(24.2±8.5) compared with (14.5±8.0) hours,P＜0.05].The proportion of women who achieved parturiency within 12 hours was significantly lower in the double-balloon catheter group than that in the control group [9％ (6/66) compared with 21％ (13/62),P＜0.05].The cesarean section rate showed no significant differences [41％ (27/66) compared with 43％(27/62),P＞0.05].The prevalence of intrauterine infection demonstrated by clinical diagnosis was significantly higher in the double-balloon catheter group [11％ (7/66) compared with 6％ (4/62),P＜O.05].The double-balloon catheter group had significantly lower rates of contraction overfrequency [0(0/66) compared with 42％ (26/62),P＜0.05],hyperthermia [3％ (2/66) compared with 19％ (12/62),P＜0.05],fetal heart rate abnormalities before removing the device or drug [5％ (3/66) compared with 19％ (12/62),P＜0.05],as well as precipitate labour [2％ (1/66) compared with 16％ (10/62),P＜0.05].Conclusions The efficacy of a double-balloon transcervieal catheter is similar to that of a prostaglandin vaginal insert.However,the double-balloon catheter cannot significantly reduce the cesarean section rate while it increases the risk of intrauterine infection.The materual and fetal safety of transcervical catheter is superior to the prostaglandin vaginal insert.In cases of oligohydramnios,fetal growth restriction,pregnancy complicated with asthma,hypertension and scar uterine are in favor of a balloon catheter using for cervical ripening on account of high risk of using prostaglandin.

Objective To investigate the effect of multidisciplinary intervenient on survival of patients with malignant tumor. Methods Six hundred and thirty-nine malignant tumor patients were randomly assigned to the intervenient and the control group. A total of 584 completed the follow-up study. The intervenient group received comprehensive treatment for 2 years,while the control group was in a process of self-rehabilitation. The 2-year survival rate was compared between the groups by using Cox proportional hazard model. Results The 2-year survival rate was 94. 74% (108/114) or 80. 67% (121/150) in II stage patients of the intervenient or control group, respectively ( P < 0. 01 ) . The 2-year survival rate was 88. 03% (163/177) or 82. 8% (184/222) in early and medium stage patients of the intervenient or control group,respectively(P <0. 01). Conclusion The multidisciplinary intervenient may help to improve the 2 year survival of early or moderate stage malignant tumors.
