To compare the chemical change of Paeoniae Radix Alba (PRA) after vinegar-baking processing, as well as the effect of vinegar types exerted on the processing, 1H NMR-based metabolomic approach combined with multivariate statistical analysis was used to investigate the different metabolites between the raw and two vinegar-baked PRA. More than thirty metabolites were identified in the 1H NMR spectrum of PRA, and the multivariate statistical analysis showed that raw and two vinegar-baked PRA could be separated obviously. After vinegar-baking, the contents of isoleucine, lactate, alanine, arginine, albiflorin, and 5-hydroxymethyl furfural (5-HMF) elevated, while those of sucrose, paeoniflorin and its analogues (calculated by benzoate) decreased. The chemical compositions of two vinegar-baked PRA were also different. Shanxi vinegar- baked PRA showed higher levels of leucine, isoleucine, valine, and albiflorin, while rice vinegar-baked PRA contained more sucrose and paeoniflorin's analogues (calculated by benzoate). And the chemical changes in Shanxi vinegar-baked PRA were greater than those of rice vinegar-baked PRA. The results revealed the chemical differences between raw and vinegar-baked PRA, as well as the influence of vinegar type on processing, in a holistic manner, the results obtained suggested that the correlations between the chemical change and the drug action after processing, as well as the vinegar type used in processing, should be further studied.

Objective To identify the antibiotic resistance, homology of imipenem-resistant Pseudomonas aeruginosa strains isolated from older in Zhejiang Hospital and the carbapenemases determinants of imipenem-resistant strains. MethodsTwo hundred and sixty-two strains of Pseudomonas aeruginosa were isolated through May 2006 to May 2009 from older in Zhejiang Hospitals. K-B method was used to determine the 16 antimicrobial agents resistance of these 262 strains. The MICs of strains to 14 antimicrobial agents were determined by agar dilution and E test method. The coding sequence of Metallo-β-lactamases (MBL) were amplified, PCR products were purified, cloned and sequenced. The homology of these isolates was analyzed by pulse-field gel electrophoresis(PFGE). ResultsOne hundred and four strains of imipenem-resistant Pseudomonas aeruginosa were screened from 262 strains. The resistant rates of 104 isolates of Pseudomonas aeruginosa to ampicillin/sulbactam and cefoperazone/sulbactam were 78.9％ and 35.9％ ; polymyxin E had a minimal resistance of 6.0％ ; minocycline had a resistance rate of 58.3％. The resistant rates to other antimicrobial agents were more than 70.0％. Twelve imipenem-resistant Pseudomonas aeruginosa strains contained MBL gene and two kinds of integron were detected from 10 of these 12 strains. Twelve strains of Pseudomonas aeruginosa belonged to 5 epidemic PFGE-clone. ConclusionAll of the imipenem-resistant Pseudomonas aeruginosa which had cause outbreaks in Zhejiang Hospital. MBL were not the most popular gene type. All of the MBL gene types were VIM-2. The blaVIM-2 gene cassettes located in diflerent class 1 integrons. The integrons dissemination was the most important style of strains spread.

OBJECTIVETo study the molecular mechanism of curcumin in human esophageal carcinoma cell line (EC109).

METHODSEC109 cells were cultivated in vitro. When 80%-90% confluence was reached, they were treated with curcumin in different concentrations (15-120 µmol/L). The effects on cell proliferation were examined by CCK-8 colorimetry. The ultrastructure of EC109 cells were detected with transmission electron microscope(TEM). The cells apoptosis was observed with laser confocal microscope(LCM) by AnnexinV-FITC/PI double staining. The proteins level of PTEN, AKT, GSK3β and Caspase 3 were tested by flow cytometry(FCM) .

RESULTSCCK-8 test showed that curcumin could inhibit the proliferation of EC109 cells in a time- and concentration-dependent manner. TEM and LCM examinations indicated that curcumin could make EC109 cells apoptosis. The data of FCM showed that curcumin could increase the expression of PTEN, GSK3β and Caspase 3, decreased the expression of AKT.

CONCLUSIONThe effects of curcumin on inhibiting proliferation and promoting apoptosis of EC109 cells were related with increased expression of PTEN and inhibition of PI3K/AKT signaling pathway.

Water soluble extract (WSE) is an important index for the quality evaluation of Astragali Radix (AR). In this study, the WSE of the wild AR from Shanxi province (SX) and the cultivated AR from Gansu Province (GS) were compared. The WSEs of two types of AR were determined according to the appendix of Chinese pharmacopoeia. Then the WSEs were subjected to NMR analysis, and the obtained data were analyzed using HCA, PCA, OPLS-DA, microarray analysis, and Spearman rank analysis. In addition, the Pearson correlation of differential metabolites were also calculated. The results showed that the WSE content of GS-AR (37.80%) was higher than that of SX-AR (32.13%). The main constituent of WSE was sucrose, and other 18 compounds, including amino acids, organic acids, were also detected. Multivariate analysis revealed that SX-AR contained more choline, succinic acid, citric acid, glutamate, taurine and aspartate, while GS samples contained more sucrose, arginine and fumaric acid. In addition, the Pearson correlations between different metabolites of the two types of AR also showed apparent differences. The results suggested that the WSE of two types of AR differs not only in the content, but also in the chemical compositions. Thus, the cultivation way is important to the quality of AR. This study supplied a new method for the comparison of extract of herbal drugs.

Objective: To investigate the role of the distal fourth fixation factor in the treatment of unstable femoral intertrochanteric fractures with intramedullary nails. Methods: A total of 108 patients with unstable femoral intertrochanteric fractures (AO type: A2.2-A.3.3) treated from Jun. 2014 to Jun. 2018 in our hospital were selected and divided into three groups. The injury was fixed with short intramedullary nails and had matched medullary cavity in group A (n=42). The injury was fixed with short intramedullary nails and had mismatched medullary cavity in group B (n=40). The injury was fixed with long intramedullary nails in group C (n=26). Operation time, intraoperative blood loss, fracture healing time, postoperative complications and clinical efficacy were compared among the three groups. The efficacy was evaluated by the Harris hip score. Results: There was no significant difference in the age, gender composition, or causes of injury between groups (P>0.05), but there was statistic difference in the AO type between groups (P<0.01). The operation time of group A was (62.26 ± 31.03) min, which was significantly shorter than that of group C ([89.54 ± 26.70] min, P<0.05), but not statistically different from group B ([64.53 ± 29.22] min, P>0.05). The amount of intraoperative bleeding in group A was (149.19 ± 45.97) mL, which was significantly less than that in group C ([230.77 ± 57.40] mL, P<0.05), but not statistically different from group B ([153.43 ± 40.30] mL, P>0.05). The fracture healing time in group B was (14.10 ± 2.22) months, which was significantly longer than that in group A ([11.43 ± 2.95] months) and group C ([12.35 ± 4.47] months, P<0.05). At the last follow-up, the Harris score in group B was 77.33 ± 8.18, which was significantly lower than that in group A and C (85.52 ± 10.76, 89.12 ± 9.14, P<0.05). Two patients in group A developed coxa vara. Eight patients had lost restoration in group B. No complications occurred in group C. There was significant difference in the incidence of complication among the three groups (Fisher exact test, P=0.013). Conclusion: The technique using the distal fourth fixation factor can reduce the complications of unstable femoral intertrochanteric fractures such as postoperative loss of restoration and internal fixation failure, shorten the fracture healing time, and achieve early weight-bearing exercise.

Objective To examine the relationship between hypercalcemia (HC) and the development of posttransplant erythrocytosis (PTE).Method 169 patients with normal graft function who underwent renal transplantation between January 1, 2012 and January 1, 2014 in 309th Hospital of PLA were retrospectively reviewed.Result 169 patients with normal graft function who underwent kidney transplantation for the first time in 309th Hospital from January 1, 2012 to January 1, 2014 were enrolled, including 121 males and 48 females.During the follow-up period, PTE appeared in 48 (28.4％) patients.Thirty-three (19.5％) patients developed HC, PTE occurred in 17/33 (51.5％) patients with HC, and in 31/136 (22.8％) patients without HC.PTE and HC were highly correlated (P＜0.001).Serum calcium levels tended to increase in patients with PTE, but significantly decreased in patients without PTE.HC patients had a higher probability of PTE (51.5％ vs.22.8％;P＜0.001).Similarly, HC was more common among patients with PTE compared with patients without PTE (35.4％ vs.13.2％;P＜0.001).Simple linear regression analysis showed that calcium concentration was independent predictor of hemoglobin levels (P＜0.01).In multivariate analysis, multiple linear regression model showed that the calcium concentration was still a significant predictor of hemoglobin levels (P＜0.001).Multivariate logistic regression analysis showed that the occurrence of HC was an independent risk factor of PTE (P =0.01).Estimated glomerular filtration rate was also associated with PTE (P =0.012).As compared with women, the relative risk of men who had PTE was 4.373 times (P＜0.05).The risk of PTE in patients with HC was about five times higher than in patients with normal blood calcium.Conclusion HC is associated with PTE.HC may lead to the increased PTE in renal transplant recipients.

Objective To analyze the clinical efficacy of multiple renal arteries on outcomes of renal donors and recipients in hand-assisted retroperitoneoscopic donor nephrectomy.Method From 2012 to 2014,121 patients underwent hand-assisted laparoscopic donor nephrectomy,including 92 cases of a single renal artery and 29 cases of multiple arteries.Donor and recipient outcomes for single artery and multiple arteries allografts were compared.Result The study included 121 pairs of donors and recipients.The demographic characteristics between multiple renal artery group and single renal artery group had no significant difference.The operative time,blood loss,postoperative complications,and hospital stay had no significant difference between two groups.Cold ischemia time and warm ischemia time in multiple renal artery group were longer than single donor renal artery group (128.5 ± 13.2 vs.50.2 ± 17.3 min,P＜0.001;196.0 ± 63.3 vs.154.1 ± 55.2 min,P=0.002,respectively).The operative time in multiple renal artery group was longer than in single renal artery group (213.5 ± 28.2 vs.182.2 ± 31.1 min,P＜0.001).There was no significant difference in blood loss,vascular complications and ureternal complications between two groups.The renal functions of two groups were likewise within one year.Conclusion There was no statistically significant difference in clinical efficacy between hand-assis-ted retroperitoneoscopic donor nephrectomy with multiple renal arteries and single artery.The use of these grafts was safe for both recipients and donors.
