Objective To discuss nicardipin′s influence on post operation cognitive dysfunction (POCD) in senior patient after hip joint replacement operation.Methods 180 senior patient, who received selective unilateral hip joint replacement operation between October 2015 and October 2016 under the condition of combined spinal-epidural anesthesia (CSEA) were randomly divided into Group A (with nicardipine) and Group B (without nicardipine).Nicardipine was only appropriately pumped into vein in time in Group A.MAP was observed and recorded 30 minutes after starting the operation and at the end of the operation.Mini-mental state examination (MMSE) was applied to score the patient one day before, one day, three days and five days after operation, and the number of POCD was recorded.Results Compared with Group B, Group A was obviously lower in MAP level (P<0.05) after 30 minutes.MMSE score of Group A was obviously higher (P<0.01) one day after operation.The number of POCD in Group A was 8 (8.89%) significantly lower than than that of Group B (19, 21.11%).Conclusion Nicardipine could maintain hemodynamic stability of senior patients receiving selective unilateral hip joint replacement operation under the CSEA and prevent POCD to a certain extent.

Objective:To analyze the drug use of a patient with intestinal obstruction induced by high dose of morphine to explore the role of clinical pharmacists during the therapeutic process. Methods:The dose titration of morphine, choice of analgesic drugs and dose conversion were adjusted by doctors and pharmacists using NRS scores of dynamic assessment for the patient. The pharmaceutical care was implemented for the patient induced by high dose of morphine. Results:The pharmaceutical supervision by clinical pharma-cists improved medication compliance of the patient. After fentanyl patches were used to replace morphine, the intestinal obstruction was relieved in the patient and the quality of life was improved. Conclusion:Clinical pharmacist can promote the rational use of opi-oids for patients with intestinal obstruction. The successful treatment of the patient with intestinal obstruction provides the reference for patients with intractable pain treated by opioids.

Objective To study the effects of acupuncture combined with Anchang powder acupoint application in the treatment of irritable bowel syndrome with diarrhea. Methods A total of 100 patients with irritable bowel syndrome with diarrhea in our hospital from July 2014 to July 2016 were enrolled.The subjects were randomly divided into the control group (n=50) and the treatment group (n=50). The control group were treated with trimebutine, while the treatment group were treated with acupuncture combined with Anchang powder acupoint application. The two groups were treated for 4 weeks. The clinical effects of the two groups after treatment were compared. The clinical symptom scale was used to evaluate the clinical symptoms, and the quality of life was evaluated by the quality of life scale (QOL) The recurrence rate after half a year heal of the two groups were compared. Results The total efficacy rate of the treatment group was 92.0% (46/50), significantly higher than 68.0% (34/50) of the control group (x2=9.000, P=0.003). After treatment, the clinical symptom integral(1.89 ± 0.95 vs.4.02 ± 1.13,t=10.202)of the treatment group were significantly lower than the control group(P<0.05).After treatment,the quality of life rating scores(34.15 ± 6.75 vs.28.47 ± 5.01,t=4.803) of the treatment group were significantly higher than the control group (P<0.01). Half a year after treatment, the recurrence rate of the treatment group was 24.1% (7/29), significantly lower than 64.7% (11/17) of the control group (x2=7.405, P=0.007). There was no significant difference of the two groups during the treatment. Conclusions Acupuncture combined with Anchang powder acupoint application showed a good efficacy for the patients with irritable bowel syndrome with diarrhea. And the treatment showed the low incidence of adverse reactions and low recurrence rate, can mprove the clinical symptom and quality of life.

This study aims to explore the diagnostic value of specific immunoglobulin E (sIgE) and specific immunoglobulin G (sIgG) of Aspergillus fumigatus in the diagnosis of allergic broncho-pulmonary aspergillosis (ABPA) and severe asthma with fungal sensitization (SAFS). A total of 17 ABPA patients and 14 SAFS patients were enrolled. The levels of sIgG [2 294.00 (1 527.00, 14 170.00) U/ml vs. 972.60 (650.90, 1 792.00) U/ml] and sIgE [8.77 (1.64, 16.85) kU/L vs. 1.04 (0.70, 2.05) kU/L] in ABPA patients were significantly higher than those in SAFS patients (P<0.05). Aspergillus fumigatus sIgG was strongly correlated with Aspergillus fumigatus sIgE (r_s=0.797, P<0.001) in ABPA patients. When combined with Aspergillus fumigatus sIgG (>1 000.00 U/mL) and Aspergillus fumigatus sIgE (>1.00 kU/L), the sensitivity was 82.3% and specificity 78.6% for the differential diagnosis of ABPA and SAFS. It demonstrates the diagnostic value of Aspergillus fumigatus sIgG and sIgE.

Objective: To explore the effects of hypoxia inducible factor-1α (HIF-1α) on P311 and its influence on the migration of murine epidermal stem cells (ESCs) under hypoxia in vitro. Methods: Two kinds of murine ESCs were isolated and obtained from 15 neonatal wild-type C57BL/6J mice and 5 congeneric source P311 gene knock-out mice, respectively. The first passage of cells were used in the following experiments after morphologic observation and detection of expression of cell surface markers CD71 and CD49f with flow cytometer. (1) After cell scratch assay, according to the random number table (the same dividing method below), ESCs of P311 gene knock-out mice were divided into normoxia group (cells were cultured with complete medium in normoxic carbon dioxide incubator, and the subsequent normoxic treatments were the same) and hypoxia group (cells were cultured in hypoxic carbon dioxide incubator containing 1% oxygen, and the subsequent hypoxic treatments were the same), with 12 inserts in each group. ESCs of wild-type mice were divided into normoxia group, pure hypoxia group, dimethyl sulfoxide (DMSO) control group (2 μL DMSO solvent was added for 1 h of normoxia treatment before hypoxia treatment), HIF-1α inhibitor group (cells were treated with 11 μmol/L HIF-1 inhibitor of 2 μL under normoxia condition for 1 h before hypoxia treatment), HIF-1α stabilizer group (the cells were treated with 2 μmol/L FG-4592 of 2 μL under normoxia condition for 1 h before hypoxia treatment), with 12 inserts in each group. Three inserts of each time point in each group were adopted respectively to measure the residual width of scratch under inverted phase contrast microscope at post scratch hour (PSH) 0 (immediately), 12, 24, and 48. (2) After hypoxia treatment, the protein level of HIF-1α in ESCs of wild-type mice was detected by Western blotting at post hypoxia hour (PHH) 0, 12, 24, and 48. (3) ESCs of wild-type mice were divided into pure hypoxia group, DMSO control group, HIF-1α inhibitor group, and HIF-1α stabilizer group as that of experiment (1) with the same treatment. The mRNA expression of P311 and expression of P311 in ESCs were determined by real-time fluorescent quantitative reverse transcription polymerase chain reaction and immunocytochemical staining, respectively, at PHH 0 (immediately), 12, 24, and 48 (with sample numbers of 12). (4) The second passage of human embryonic kidney 293 (HEK-293) cells were divided into empty vector hypoxia group (cells were cultured under hypoxia condition after being transfected with empty vector plasmid), P311 normoxia group (cells were cultured under normoxia condition after being transfected with P311 reporter gene plasmid), P311 hypoxia group (cells were cultured under hypoxia condition after being transfected with P311 reporter gene plasmid), P311 hypoxia+ HIF-1α inhibitor group (cells which were incubated with HIF-1α inhibitor were cultured under hypoxia condition after being transfected with P311 reporter gene plasmid). The luciferase activity was detected at post culture hour (PCH) 0 and 12, respectively, and then the P311 transcriptional regulatory binding site of HIF-1α and the promoter sequence of P311 were predicted and searched by bioinformatics methods. Data were processed with factorial design variance analysis, one-way analysis of variance, LSD test and Bonferroni correction. Results: (1) The results of ESCs. The cells showed cobblestone-like pattern and different clonal morphology due to the different cell proliferation potential. The proportion of CD71^-CD49f⁺ cells accounted for about 85%. The identification results indicated that the cells showed strong stem cell properties and high purity. Compared with those in cells of normoxia group of P311 gene knock-out mice, the residual widths of scratch of cells in pure hypoxia group were smaller at PSH 12 and 24 (with P values below 0.05), and those in hypoxia group, normoxia group of wild-type mice, DMSO control group, HIF-1α inhibitor group, and HIF-1α stabilizer group were smaller at PSH 12 (with P values below 0.05). Compared with those in cells of normoxia group of wild-type mice, the residual widths of scratch of cells in hypoxia group, pure hypoxia group, and DMSO control group were smaller at PSH 12 and 24 (with P values below 0.05), and the residual width of scratch of cells in HIF-1α stabilizer group was smaller at PSH 12 (P<0.05). Compared with those of cells in pure hypoxia group, the residual widths of scratch of cells in hypoxia group were wider at PSH 12 and 24 (with P values below 0.05), and the residual width of scratch of cells in HIF-1α inhibitor group was wider at PSH 12 (P<0.05), and those of cells in HIF-1α stabilizer group were smaller at PSH 12 and 24 (with P values below 0.05). There was no obvious difference in the width of scratch in cells among the 7 groups (F=19.02, P>0.05). The protein levels of HIF-1α in ESCs of wild-type mice at PHH 0, 12, 24, and 48 were respectively 1.02±0.05, 2.56±0.09, 1.60±0.17, and 1.17±0.03. Compared with that at PHH 0, the protein level of HIF-1α at PHH 12 was significantly enhanced (P<0.01). It began to decline at PHH 24 but was still higher than that at PHH 0 (P<0.05), and the protein level of HIF-1α at PHH 48 was close to the normoxia level (P>0.05). Compared with those of cells in pure hypoxia group, the mRNA expressions of P311 of cells in HIF-1α inhibitor group were significantly decreased at each time point (with P values below 0.05), and those in HIF-1α stabilizer group were significantly increased at PHH 12 and 24 (with P values below 0.05). Compared with those of cells in HIF-1α inhibitor group, the mRNA expressions of P311 of cells in DMSO control group and HIF-1α stabilizer group were significantly increased at PHH 0, 12, and 24 (with P values below 0.05). Compared with those of cells in pure hypoxia group, the expressions of P311 of cells in HIF-1α inhibitor group were significantly decreased at each time point (with P values below 0.05), while those in HIF-1α stabilizer group were significantly increased at PHH 12 and 24 (with P values below 0.05). Compared with those of cells in HIF-1α inhibitor group, the expressions of P311 of cells in DMSO control group and HIF-1α stabilizer group were significantly increased at PHH 12 and 24 (with P values below 0.05). (2) The results of HEK-293 cells. At PCH 0, there was no significant difference in the luciferase activity among cells of empty vector hypoxia group, P311 normoxia group, P311 hypoxia group, and P311 hypoxia+ HIF-1α inhibitor group (F=13.33, P>0.05). At PCH 12, the luciferase activity of cells in P311 hypoxia group was higher than that in empty vector hypoxia group (P<0.01). The luciferase activity of cells in hypoxia group was higher than that in P311 normoxia group (P<0.05), while that of cells in P311 hypoxia+ HIF-1α inhibitor group was lower than that in P311 hypoxia group (P<0.01). Conclusions HIF-1α may increase the migration of murine ESCs through inducing the expression of P311 at the early stage of hypoxia.

OBJECTIVETo explore the interaction between P311 and transforming growth factor beta 1 (TGF-β1) in murine fibroblasts and its effect on the function of fibroblasts.

METHODSSkin fibroblasts obtained from five neonatal P311 wild-type C57BL/6 mice and P311 gene knock-out C57BL/6 mice were cultured. The second passage of fibroblasts were used in the following experiments. All experiments were repeated for 3 times. (1) The fibroblasts of P311 wild-type mice were divided into blank control group and P311 over-expression group according to the random number table (the same grouping method below), with 36 wells in each group. Fibroblasts in blank control group were transfected with 10 μL control vector, and fibroblasts in P311 over-expression group were transfected with equal efficiency P311 expression adenovirus vector. After being cultured for 48 hours, the mRNA expression level of P311, and the mRNA and protein expression levels of TGF-β1, α-smooth muscle actin (α-SMA), and collagen type I of fibroblasts in both groups were determined with real-time fluorescent quantitative RT-PCR and Western blotting (the same detection methods below), respectively. (2) After cultured reaching the cell density of 80%-90%, the mRNA and protein expression levels of TGF-β1, α-SMA, and collagen type I of the fibroblasts of P311 wild-type mice and P311 gene knock-out mice, with 4 flasks in each type of fibroblasts, were determined. (3) The fibroblasts of P311 wild-type mice were divided into blank control group and 5, 10, 15, 20, and 25 ng/mL TGF-β1 groups after being starved treatment with DMEM medium containing 1% FBS for 3 hours, with 2 flasks in each group. Fibroblasts in blank control group were routinely cultured, while fibroblasts in the latter five groups were treated with 5, 10, 15, 20, and 25 ng/mL TGF-β1, respectively. After being cultured for 48 hours, the mRNA expression levels of P311 in fibroblasts of the six groups were determined. Another fibroblasts of P311 wild-type mice were divided into blank control group and 10 ng/mL TGF-β1 group, with 6 wells in each group, and the protein expression levels of P311 in both groups were determined by immunofluorescence staining. (4) The fibroblasts of P311 wild-type mice were divided into blank control group and 10 ng/mL TGF-β1 group after being starved treatment as above, with 2 flasks in each group, and fibroblasts in blank control group were routinely cultured, while fibroblasts in the latter group were treated with 10 ng/mL TGF-β1. After being cultured for 48 hours, the mRNA and protein expression levels of α-SMA and collagen type Ⅰ were determined. The fibroblasts of P311 gene knock-out mice were grouped and treated as above, and the mRNA and protein expression levels of α-SMA and collagen type I were determined. Data were processed with one-way analysis of variance and t test.

RESULTS(1) The mRNA expression level of P311 of fibroblasts in P311 over-expression group was increased nearly 300 000-fold compared with that in blank control group (t=9.942, P<0.001). The mRNA expression levels of TGF-β1, α-SMA, and collagen type I of fibroblasts in P311 over-expression group, and the protein expression levels of pro-TGF-β1, activated TGF-β1, α-SMA, and collagen type I of fibroblasts in P311 over-expression group were significantly higher than those in blank control group (with t values from 8.192 to 49.090, P values below 0.01). (2) The mRNA expression levels of TGF-β1, α-SMA, and collagen type I in fibroblasts of P311gene knock-out mice were significantly lower than those in fibroblasts of P311 wild-type mice (with t values from 8.157 to 22.270, P values below 0.01). The protein expression levels of pro-TGF-β1, α-SMA, and collagen type I in fibroblasts of P311 gene knock-out mice were significantly lower than those in fibroblasts of P311 wild-type mice (with t values from 2.995 to 12.600, P<0.05 or P<0.01), and the protein expression levels of active TGF-β1 were similar in two types of fibroblasts (t=1.070, P>0.05). (3) The mRNA expression levels of P311 of fibroblasts in blank control group and 5, 10, 15, 20 and 25 ng/mL TGF-β1 groups were 1.28 ± 0.44, 3.61 ± 0.91, 6.64 ± 0.92, 6.58 ± 1.04, 1.79 ± 0.31, 0.16 ± 0.06, respectively. Compared to the mRNA expression level of P311 of fibroblasts in the blank control group, the mRNA expression levels of P311 of fibroblasts in 5 and 20 ng/mL TGF-β1 groups were similar (with t values respectively 2.302 and 0.955, P values above 0.05), while they were significantly higher in 10 and 15 ng/mL TGF-β1 groups (with t values respectively 5.630 and 4.710, P values below 0.001), and they were significantly lower in 25 ng/mL TGF-β1 group (t=2.509, P<0.01). The protein expression level of P311 of fibroblasts in 10 ng/mL group was higher than that in blank control group. (4) The mRNA and protein expression levels of α-SMA and collagen type I of fibroblasts of P311 wild-type mice in 10 ng/mL TGF-β1 group were significantly higher than those in blank control group (with t values from 3.523 to 14.290, P<0.05 or P<0.01). The mRNA and protein expression levels of α-SMA and collagen type I of fibroblasts of P311 gene knock-out mice in 10 ng/mL TGF-β1 group were significantly higher than those in blank control group (with t values from 4.895 to 14.870, P<0.05 or P<0.01).

CONCLUSIONSThe interaction between P311 and TGF-β1 in murine fibroblasts exists and it may enhance the differentiation of fibroblasts in combination.
