Background: Delivery of drug admixtures by intravenous patient-controlled analgesia is a common practice for the management of postoperative pain; however, analytical confirmation of the compatibility and stability of butorphanol tartrate, ketamine hydrochloride, and droperidol combined in ternary admixtures is not available. Methods: Butorphanol tartrate, ketamine hydrochloride, and droperidol have been examined for compatibility and stability when combined with 0.9% sodium chloride injection stored at 4°C and 25°C with light protection for a total of 14 days. Concentrations were 0.067 mg/mL, 1.33 mg/mL, and 0.033 mg/mL for butorphanol tartrate, ketamine hydrochloride, and droperidol, respectively. Drug concentrations were determined using high-performance liquid chromatographic analysis. Results: All three drugs were very stable (> 97%) at 4°C and 25°C for 14 days. The ternary admixtures were initially clear and colorless throughout the observation period, and the pH value did not change significantly. Conclusion: The results confirm that the ternary admixture of butorphanol tartrate 0.067 mg/mL, ketamine hydrochloride 1.33 mg/mL, and droperidol 0.033 mg/mL in 0.9% sodium chloride injection were stable for 14 days when stored in polyolefin bags at 4°C and 25°C and protected from light. © 2016 Fang et al.

This study shows the expression pattern of calcitonin gene-related peptide (CGRP) in the anterior and posterior horns of the spinal cord after brachial plexus injury. The animals were divided into three injury groups: group 1, right C7 anterior root avulsion; group 2, right C7 anterior root avulsion and cut right C5-T1 posterior roots; and group 3, right C7 anterior root avulsion plus right hemitransection between the C5 and C6 segments of the spinal cord. These animals were killed at 1, 3, 7 and 14 days after injury. In the anterior horn of all three injured groups, the expression of CGRP increased progressively from day 1 to day 7 (p < 0.05), peaked on day 7, and then began to decrease slowly. In the posterior horn of all three injured groups, the expression of CGRP decreased gradually from day 1 to day 14 after the operation and was significantly lower on day 14 compared to day 1. At each time point (days 1, 3, 7 and 14), the expression of CGRP was the highest in group 1 and the lowest in group 2, with significant differences among the three groups. The CGRP in the anterior horn of the spinal cord was derived from the cell bodies of motor neurons and was possibly involved in repair mechanisms and regeneration after nerve injury. However, the CGRP in the posterior horn was mainly derived from the posterior root ganglion and was possibly associated with the conduction of noxious stimulation. © 2009 Elsevier Ltd.

AIM: To investigate the relationship between donor liver cold preservation, lung surfactant (LS) changes and acute lung injury (ALI) after liver transplantation. METHODS: Liver transplantation models were established using male Wistar rats. Donor livers were preserved in University of Wisconsin solution at 4 °C for different lengths of time. The effect of ammonium pyrrolidinedithiocarbamate (PDTC) on ALI was also detected. All samples were harvested after 3 h reperfusion. The severity of ALI was evaluated by lung weight/body weight ratio, lung histopathological score, serum nitric oxide (NO) and endothelin (ET)-1 levels, lung tumor necrosis factor (TNF)-α and interleukin (IL)-1β levels. Lung surfactants (LSs) were determined by micellar electrokinetic capillary chromatography. RESULTS: With extended donor liver cold preservation time (CPT), lung histopathological scores, serum ET-1 levels, lung weight/body weight ratio and the level of TNF-α and IL-1β in lung were increased significantly in the 180-min group compared with the sham group (3.16 ± 0.28 vs 1.12 ± 0.21, P < 0.001; 343.59 ± 53.97 vs 141.53 ± 48.48, P < 0.001; 0.00687 ± 0.00037 vs 0.00557 ± 0.00056, P < 0.001; 17.5 ± 3.0 vs 1.3 ± 0.3, P < 0.001; 10.8 ± 2.3 vs 1.8 ± 0.4, P < 0.001), but serum NO levels decreased remarkably (74.67 ± 10.01 vs 24.97 ± 3.18, P < 0.001). The expression of lung phosphatidylcholine (PC), phosphatidylethanolamine (PE), phosphatidylinositol (PI) and phosphatidylserine (PS) increased when CPT was < 120 min, and decreased when CPT was > 180 min (PC: 1318.89 ± 54.79 vs 1011.18 ± 59.99, P < 0.001; PE: 1504.45 ± 119.96 vs 1340.80 ± 76.39, P = 0.0019; PI: 201.23 ± 34.82 vs 185.88 ± 17.04, P = 0.2265; PS: 300.43 ± 32.95 vs 286.55 ± 55.55, P = 0.5054). All these ALI-associated indexes could be partially reversed by PDTC treatment. CONCLUSION: Prolonged CPT could induce or inhibit the expression of LSs at the compensation or decompensation stage, and some antioxidants (e.g., PDTC) may reverse the pathological process partially. © 2012 Baishideng.

Background: We have observed at our clinical work that acute lung injury (ALI) often occurs in patients transplanted with donor livers persevered for long time. So, we conducted this study to investigate the influence of cold preservation time (CPT) of donor liver on ALI induced by liver transplantation (LT), and further study the role of nuclear factor-κB (NF-κB) in the process. Methods: Wistar rats were used as donors and recipients to establish orthotopic rat liver transplantation models. Donor livers were preserved at 4°C for different lengths of time. The effect of NF-κB inhibitor, ammonium pyrrolidinedithiocarbamate (PDTC), on ALI was detected. All samples were harvested after 3 h reperfusion. The severity of liver injury was evaluated first. The expressions of tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) in liver tissue and liver outflow serum were measured respectively. The severity indexes of ALI, the activity of NF-κB and inhibitor-κBα (I-κBα) in lung/liver were measured accordingly. Results: With the prolonged liver CPT, the liver damage associated indexes and ALI-related indexes all increased significantly. TNF-α and IL-1β in liver outflow serum increased accordingly, and the activity of NF-κB in liver/lung increased correspondingly. All these ALI-associated indexes could be partially reversed by the use of PDTC. Conclusions: Extended CPT aggravates the damage of donor liver and induces the expressions of TNF-α and IL-1β in liver. These inflammatory factors migrate to lung via liver outflow blood and activate NF-κB in lung, inducing ALI finally. NF-κB may play a critical role in LT-related ALI. Patients with or at risk of ALI may benefit from acute anti-inflammatory treatment with PDTC. © 2011 Jiang et al.

Purpose. The stability of admixtures containing butorphanol and granisetron in polyolefin bags and glass bottles stored at 4 and 25 °C was studied. Methods. Commercial solutions of butorphanol tartrate and granisetron hydrochloride were combined and further diluted with 0.9% sodium chloride injection to final concentrations of butorphanol tartrate 0.08 mg/mL and granisetron 0.03 or 0.06 mg/mL; the resulting mixtures were packaged in polyolefin bags and glass bottles. The admixtures were assessed for periods of up to 48 hours after storage at 25 °C without protection from room light and up to 14 days at 4 °C with protection from room light. The chemical stability of the admixtures was evaluated by a validated high-performance liquid chromatography (HPLC) method and by measurement of pH values. Solution appearance and color were assessed by observing the samples against room light and dark backgrounds. Results. HPLC analysis demonstrated that the percentages of the initial concentrations of butorphanol and granisetron in the various solutions remained above 97% during the testing period. No changes in color or turbidity were observed in any of the prepared solutions. Throughout this period, pH values remained stable. Conclusion. Admixtures of butorphanol tartrate 0.08 mg/mL and granisetron 0.03 or 0.06 mg/mL in 0.9% sodium chloride injection in polyolefin bags or glass bottles remained stable for 48 hours when stored at 25 °C exposed to room light and for 14 days when stored at 4 °C protected from room light.

OBJECTIVE: To determine the age-and education-corrected control values for the number connection test (NCT) and digit symbol test (DST) psychometric measures to increase their accuracy for diagnosis of minimal hepatic encephalopathy (MHE).METHODS: The NCT Part A (NCT-A) and DST were administered to 843 healthy volunteers (age range:16-65 years; education:more than 1 year) and 429 patients with liver cirrhosis (with Child-Pugh classification of liver function). The normal values were defined as the mean ± 2 standard deviations (2SD);MHE was defined by abnormal results on at least one psychometric test. The statistical significance of differences in MHE diagnosis according to the various control values (age and education-corrected or not) was assessed by the chi-square test and logistic regression analysis.RESULTS: NCT-A and DST were found to be influenced by age (standard coefficient 0.405, P =0.000 and standard coefficient-0.527, P =0.000 respectively) and education (standard coefficient-0.347, P =0.000 and standard coefficient 0.405, P =0.000 respectively). Among the 120 patients with liver cirrhosis who were diagnosed with MHE (27.97%), 113 had abnormal NCT-A results (26.34%), 54 had abnormal DST results (12.59%),and 47 had abnormal results on both tests (10.96%). Among these 120 MHE-positive patients, 21 were classified as Child-Pugh A (19.81%), 46 as Child-Pugh B (23.71%), and 53 as Child-Pugh C (41.09%);the MHE-positive rate was significantly greater in the patients with Child-Pugh C classification than those with either Child-Pugh B or Child-Pugh A (P < 0.01). Logistic analysis showed that when the control data was corrected for age and education, the MHE diagnosis was related with liver function (P =0.000), regardless of age (P =0.328) and education (P =0.563). When the control data was uncorrected, the MHE diagnosis was not only influenced by liver function (P =0.000) but also by age (P =0.000) and education (P =0.005).CONCLUSION: Age and education-corrected control values can increase the accuracy of MHE diagnosis by NCT-A and DST.

Hepatocellular carcinoma (HCC) is considered as a disease of dysfunction of the stem cells. Studies on stem cells have demonstrated that Oct4 plays a pivotal role in embryo regulation. In order to understand the role of Oct4 in HCC and the relationship among Oct4 and wnt/β-catenin and TGF-β signal pathways, we have detected the expression of Oct4, Nanog, Sox2, STAT3 as well as the genes in wnt/β-catenin, and TGF-β families in HCC cell lines and in tumor specimens from HCC patients. The authors found that Oct4 was expressed in all of the four HCC cell lines and the tumor specimens from HCC patients. Some other genes were also expressed in them with different level including Nanog, Sox2, STAT3 and TCF3, wnt10b, β-catenin, ELF, Smad3 and Smad4. The ability of the clone formation and migration of the HepG2 decreased after Oct4 was knockdowned. Silencing of Oct4 and TCF3 in HCC cell line HepG2 revealed that there were complicated relationships among Oct4, wnt/β-catenin family and TGF-β family genes. Knockdowning Oct4 reduced the expression of TGF-β family genes ELF, Smad3, Smad4 and wnt/β-catenin family genes, wnt10b, and β-catenin but increased TCF3. In reverse, knockdowning TCF3 led to the increased expression of Oct4 and TGF-β family genes. In conclusion, the expression of Oct4 in HCC may play an important role as in stem cell. Because Oct4 improves not only the function of wnt/β-catenin, but also the TGF-β signal pathways, the significance of its expression in HCC might be more complicated than we evinced before. © 2010 Springer Science+Business Media, LLC.

Rhizoma Atractylodes Macrocephalae (RAM) contains several sesquiterpene compounds including atractylenolide III (AO-III). This bioactive compound may be used as a chemical marker for the quality control of different processed RAM products.To develop and validate an RP-HPLC method for the quantitative determination of AO-III in RAM and in a variety of processed RAM products.HPLC was carried out using a Kromssil C(18) RP-column eluted with methanol-water (70:30) at a flow rate of 1.0 mL/min and with UV detection at 220 nm. Full validation was performed using standard methods.The linear range of AO-III was 5-50 g/mL; the regression equation was y = 10210x + 11194 (r = 0.9994) and the average recovery was 101.08% (RSD = 0.98%). The detection and quantification limits for AO-III were determined to be 0.005 and 0.018 g/mL at signal-to-noise ratios of approximately 3:1 and 10:1, respectively.The described HPLC method is appropriate for quality assurance and differentiation of AO-III in RAM and different processed products.
