Objective:To investigate the effect of upper limb pillow position on hemodynamic and safety of patients undergoing cerebellopontine angle tumor resection.Methods:Eighty-four patients receiving cerebellopontine angle tumor resection in our hospital from January 2016 to December 2019 were randomly divided into the experimental group (42 cases) and the control group (42 cases). Patients in the control group were placed in routine upper limb position, while patients in the experimental group were placed in upper limb pillow position. The data including systolic pressure, diastolic pressure, heart rate, saturation of blood oxygen were recorded on admission of operation room, completing placing body position, 30 minutes and 60 minutes after operation and after finishing the operation. The numbness/soreness of upper limbs and pressure injury rate was compared between the experimental group and the control group.Results:The rate of numbness/soreness of upper limbs were 2.4% (1/42) in the experimental group, 19.1%(8/42) in the control group, the differences were statistically significant ( χ2 value was 6.098, P<0.05). The stage 1 pressure injury were 2 cases in the experimental group, stage 1 and 2 pressure injury were 6 cases and 2 cases, respectively in the control group, the differences were statically significant ( Z value was 2.039, P<0.05). Conclusion:Upper limb pillow position of the operation side can reduce postoperative complication of patients undergoing cerebellopontine angle tumor resection, but will not increase the risk of abnormal hemodynamic fluctuation.

AIM: To determine the relationship between antigen-induced airway inflammation characterized by pulmonary eosinophilia and bronchial hyperreactivity in rats, and to evaluate the effect of theophylline at different doses. METHODS: In ovalbumin (OA)-sensitized rats, bronchiole wall area, eosinophils around bronchi, and the responses to methacholine (MCh) aerosol were measured after 1% OA aerosol challenge with computer-assisted techniques. RESULTS: OA challenge caused both inflammation and airway hyperreactivity, and there was a significantly positive correlation between them. Oral theophylline (1-12.5 mg/kg, bid for 7 days) attenuated antigen-induced inflammation (swelling of bronchiole walls and pulmonary eosinophilia) and bronchial hyperreactivity. CONCLUSION: These findings confirm that bronchial hyperreactivity positively correlates to airway inflammation in the rat, and suggest that theophylline at relatively lower doses has anti-inflammatory effect in airway allergic reaction.

This study is to prepare scopolamine hydrobromide nanoparticles-in-microsphere system (SH-NiMS) and evaluate its drug release characteristics in vitro. SH nanoparticles were prepared by ionic crosslinking method with tripolyphosphate (TPP) as crosslinker and chitosan as carrier. Orthogonal design was used to optimize the formulation of SH nanoparticles, which took the property of encapsulation efficiency and drug loading as evaluation parameters. With HPMC as carrier, adjusted the parameters of spray drying technique and sprayed the SH nanoparticles in microspheres encaposulated by HPMC was formed and which is called nanoparticles-in-microsphere system (NiMS). SH-NiMS appearances were observed by SEM, structure was obsearved by FT-IR and the release characteristics in vitro were evaluated. The optimized formulation of SH nanoparticles was TPP/CS 1:3 (w/w), HPMC 0.3%, SH 0.2%. The solution peristaltic speed of the spray drying technique was adjusted to 15%, and the temperature of inlet was 110 degrees C. The encapsulation product yeild, drug loading and particle sizes of SH-NiMS were 94.2%, 20.4%, and 1256.5 nm, respectively. The appearances and the structure of SH-NiMS were good. The preparation method of SH-NiMS is stable and reliable to use, which provide a new way to develop new dosage form.

Objective To investigate the applicability of Cys C-based formulas for prediction of GFR in Chinese patients with CKD.Methods A total of 176 adult patients with CKD including 90 males and 86 females collected from 4 hospitals located in different geographic regions of China (Beijing,Shanghai,Dalian and Changsha) were enrolled in this study from September 2007 to July 2009.The rGFR was measured using 99mTc-DTPA clearance rate two-sample method.Cystantic C was measured by PETIA and PENIA respectively.The results of eGFR in the Larsson formula,Grubb formula,Hoek formula,Filler formula,Stevens formula and Hojs formula were compared with the rGFR to evaluate the calculation coherence,bias,precision,accuracy and the performance of correct phasing of the formulas.Results The mean 99mTc-DTPA clearance was [40.70 ( 19.09 - 86.49)] ml · min-1 · ( 1.73m2 ) -1.Significant difference was witnessed in the evaluation of GFR estimation formulas calculated by PETIA and PENIA (P ＜0.01).ICC and Spearman correlation analysis revealed a significant correlation between eGFR and rGFR.The ICCs of eGFR and rGFR ranged from 0.874 to 0.938.Compared with rGFR,the 30％ accuracy of all the eight evaluation formulas using PETIA and PENIA method were lower than 60％.The percentages of correct phasing in all the 5 stages of CKD were not ideal.With these formulas,percentages of correct phasing from CKD stage 2 to CKD stage 4 were lower than 65％.The eGFRs were underestimated by formulas evaluated by PENIA in CKD stage 1.All the eGFRs were overestimated remarkably by all equations in CKD stage 5.Conclusions None of the eight Cys C based formulas are ideal for estimation of GFR in Chinese CKD patients,and they can not be applied to Chinese patients directly.For this patient population,further studies will be needed to develop a more accurate Cys C-based GFR estimation formula that includes ethnicity,age and other factors.

Objective To investigate the association of serum levels of matrix metalloproteinase-12 (MMP-12) and a functional polymorphism in the promoter - 82A/G of the MMP-12 gene with acute atherosclerotic cerebral infarction (ACI).Methods All 608 cascs of acute ACI and 374 healthy controls were included in the study.Serum levels of MMP-12 were measured using the enzyme-linked immunosorbent assay (ELISA). At the same time,polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was performed on the - 82A/G polymorphism in the MMP-12 gene.Results The serum levels of MMP-12 in ACI group (( 17.36 ± 9.12) ng/ml) were not significantly higher than those in the healthy control group ( ( 17.42 ± 7.70) ng/ml,t ＝ 0.047,P =0.962).The frequency of the AG + GG genotypes was not significantly different between the two groups (7.6％ vs 5.9％,x2 =0.281,P =0.584),and the frequencies of the G allele were 3.8％ and 2.9％ in the ACI group and the control group respectively which were also not significantly different between the two groups ( x2 =0.746,P =0.374).Conclusion There is no correlation between serum level with genetic polymorphism in MMP-12 promoter (-82A/G) and cerebral infarction.

OBJECTIVETo study the clinicopathologic and immunohistochemical features of diffuse large B-cell lymphoma (DLBCL) and the significance of immunohistochemistry in diagnosis and differential diagnosis of DLBCL.

METHODS60 cases of DLBCL were studied and immunohistochemical staining for LCA, L26, BLA-36, CD30, bcl-6 were carried out with the EnVision 2 step method.

RESULTSThe age range of 76.7% (46/60) patients was 40 - 70 years. The location of the lesion includes nodal and extranodal sites. 90.0% (54/60) were in clinical stages of II (24/54), III (21/54), IV (9/54). Histopathologic morphology presented as centroblastic (88.3%, 53/60), immunoblastic (3.3%, 2/60), anaplastic large B cell type (3.3%, 2/60) and T cell rich B cell type (5.0%, 3/60). Immunostaining showed 100% (60/60) DLBCL were positive for LCA, L26, BLA36, 3.3% (2/60) DLBCL positive for CD30, 95% (57/60) expressed bcl-6 protein.

CONCLUSIONSDLBCL is an aggressive lymphoma which shows cytologic variability from case to case. The evaluation of pathologic features and immunohistochemistry in DLBCL are useful and practical for diagnostic purposes, but cannot delineate distinctive morphologic subtypes.

Objective To observe the effects of 630 nm red light and 460 nm blue light emitting diode irradiation on the healing of skin wounds in Japanese big-ear white rabbits. Methods The skin wound model was established with 8 Japanese big-ear white rabbits. Three parts of vulnus in each rabbit were used:two parts of vulnus were irradiated vertically by red and blue LED light,respectively(15 min/time),and the distance between lights and wounds was 15 cm;the 3part of the wound was used as a control. On the 21day of the wounds exposure to light,the number of healing wounds and the percentage of healing area were recorded and the treatment effect of these two light sources was compared. HE staining was used to analyze the newborn tissue structure. Masson staining was used to observe the proliferation of skin collagen fibers. Immuohistochemical staining was used to analyze fibroblast growth factor(FGF),epidermal growth factor(EGF),endothelial growth factor(CD31),proliferating cell nuclear antigen(Ki-67),and inflammatory cytokines(CD68)infiltration in the skin. Results The healing rate in the red light,blue light,and control groups was 50.0%(4/8),25.0%(2/8),and 12.5%(1/8),respectively. Since the 12day after modeling,the healing area percentage in the red light group was significantly higher than those in the blue light and control groups(P<0.05,P<0.01). On the 21day after modeling,the skin thickness of the red light group was(2.95±0.34)mm,which was significantly higher than that in control group [(2.52±0.42)mm;F=3.182,P=0.016)]. The average optical density of collagen fibers was 0.15±0.03 in red light group,which was significantly higher than that of the blue light group(0.09±0.01;F=7.316,P=0.012)and control(0.07±0.01;F=7.316,P=0.003). The results of immunohistochemistry showed the expression levels of EGF,FGF,CD31 antigen,and Ki-67 in the red light group were significantly higher than those in the blue light and control groups,whereas the CD68 expression was significantly lower(P<0.05 or P<0.01). Conclusion LED red light irradiation can promote the healing of skin wounds in Japanese big-ear white rabbits,which may be achieved by the effect of red light irradiation in stimulating the proliferation of skin epidermal cells,vascular endothelial cells,and fiberous tissue.
