Objective To investigate the effect of cerebroprotein hydrolysate on the serum high sensitivity C reactive protein (hsCRP), insulin-like growth factor-1 (IGF-1) and interleukin-18 (IL-18) in patients with hypoxic ischemic encephalopathy (HIE) in plateau region. Methods From January, 2013 to May, 2015, 104 cases with neonatal HIE in our department were randomly divided into conventional treat-ment group (n=52) and cerebroprotein hydrolysate group (n=52). Besides, 35 cases of healthy newborn were chosen as the control group. The total effective rate and the serum hsCRP, IGF-1, IL-18 levels were compared. Results The IGF-1 level was lower, and the levels of hsCRP and IL-18 were higher in moderate HIE group and severe HIE group than in the control group and the mild HIE group, respectively (P<0.05). The efficiency rate was significantly higher in the cerebroprotein hydrolysate group than in the conventional treatment group (χ2=8.922, P=0.012). Compared with the conventional treatment group, the IGF-1 level increased, and the levels of hsCRP and IL-18 decreased in the cerebroprotein hydrolysate group (P<0.05). Conclusion Cerebroprotein hydrolysate is effective on patients with HIE in plateau re-gion. The changes of serum hsCRP, IGF-1, and IL-18 levels can be used as auxiliary indexes for early diagnosis of HIE.

Objectives To explore the characteristics and value of magnetic resonance imaging (MRI) in predicting prognosis of hypoxic ischemic encephalopathy (HIE) in neonatal period, at 4 months and 4 years old. Methods Twenty-four patients with HIE were examined by MRI. Their MRI results in the neonatal period, at month 4 and year 4 and neurological functions at year 4 were compared. Results Periventricular signal alterations and deep gray matter involvement were common in HIE neonates. The neonates with deep gray matter involvement usually had neurological malfunction and poor prognosis. The patients with encephalomalacia and periventricular leukomalacia at 4 months and 4 years old also had poor prognosis. The abnormal MRI ifndings in HIE children at 4 month and 4 year old predicted the occurrence of neurological malfunction. Con-clusions The MRI of infant at 4 months old is important in prediction of neurological malfunction and provides guidance of clinical intervention for children with HIE.

Objective To explore the perioperative nursing care of cooled radiofrequency for refractory craniofacial postherpetic neuralgia.Methods 13 refractory craniofacial postherpetic neuralgia patients were reviewed. Results Visual analogue score significantly decreasedafter the treatment (P<0.01), and severe dropsy after treatment was relieved in 2~3 weeks. Conclusion The cooled radiofrequency iseffective on refractory craniofacial postherpetic neuralgia, while the perioperative nursing care was safe, feasible, and worthy for more application.

Objective: To study the efficacy and safety of the intrapleural injection of nedaplatin combined with recombinant hu-man endostatin (Endostar) in the treatment of malignant pleural effusion in non-small cell lung cancer (NSCLC) patients. Methods:Seventy patients diagnosed with NSCLC with malignant pleural effusion were treated by intrapleural injection. The subjects were divid-ed into two groups, as follows: 35 cases were injected with nedaplatin and Endostar (the treatment group) and 35 cases were injected with nedaplatin only (the control group). One month after the treatment, the clinical efficacy and toxicity were evaluated. The clinical ef-ficacy, quality of life, and toxic reaction were compared between the two groups. Results: The short-term clinical efficacy rate of the treatment group was 74.28%, whereas that of the control group was 48.57%, and the difference between the two groups was significant (P<0.05). Adverse effects such as nausea vomiting and leukopenia, occurred in both groups, but no significant differences were found between the two groups (P>0.05). Conclusion: The efficacy of the intrapleural injection of recombinant human endostatin combined with nedaplatin is superior to that of cisplatin alone in the treatment of malignant pleural effusion, without increasing chemotherapeutic toxicity.

Objective To analyze the clinical features and prognostic factors of patients with malignant tumor complicated by acute kidney injury (AKI),and provide the basis for preventing AKI and improving the prognosis.Methods Malignant tumor patients complicated by AKI were screened with the electronic medical records system from January 2001 to December 2012 at the Affiliated Hospital of Qingdao University.The clinical characteristics in the 12 years were analyzed by statistical analysis and compared.The risk factors of the hospital mortality in malignancies tumor complicated by AKI were analyzed by Logistic regression analysis.Results A total of 100 patients with malignant tumor complicated by AKI were collected,accounting for 24.94％ of AKI patients and 1.66‰ of malignant tumor patients at the same period.Malignancies were consist of hematologic malignancies (11％),non-metastatic solid tumor (47％),metastatic solid tumor (42％).The most common factor leading to AKI for malignancies was post-renal obstruction (64％),followed by nephrotoxic drugs or contrast agents (24％),hypovolemia (18％).There was no significant change of the etiologies for AKI between the first six-year and the second six-year (P ＞ 0.05).The hospital mortality of patients with malignant tumor complicated by AKI was 25％,and multivariate Logistic regression analysis showed that multiple etiologies (OR=13.356),multiple organ failure (OR=222.256),and metastatic solid tumors (OR=8.497) were the independent risk factors for hospital mortality.Conclusions AKI is a common complication in patients with malignant tumors,and the most common factor leading to AKI is postrenal obstruction.The hospital mortality in malignancies with AKI is high,which should get the attention of clinicians.

Objective To observe the expression of cysteine rich-protein 61 (Cyr61) on renal tubular cells,to explore its effects against hypoxic induced kidney injury and the underlying mechanisms.Methods A stably Cyr61 expressed tubular cell line Cyr61-HK2 was established based on HK2 cells and recombinant Cyr61-lentivirus.BrdU incorporation assay was used for cell proliferation.The apoptosis of cells was analyzed by flow cytometry with Annexin V and propidiumiodide staining.Western bloting was used to detect the protein expression of BAD,Akt and ERK.Results (1) Cyr61-HK2 cells displayed more proliferation ability than HK2 cells.(2) Under hypoxia condition,the apoptosis of both HK2 and Cyr61-HK2 cells increased,but the apoptosis of Cyr61-HK2 cells was lesser than HK2 cells.(3) The expression of Cyr61 led to the phosphorylation of BAD,Akt and ERK on 0 h,0.5 h,1 h (all P ＜ 0.05).Conclusion The expression of Cyr61 can promote cell proliferation and dampen cell apoptosis induced by hypoxia,which may be involved in the Akt/ERK signal pathway.

Objective:To determine the relationship among tumor malignancy, invasion, and plasma D-dimer (DD) levels via a retrospective analysis of the correlation between preoperative plasma DD levels and postoperative pathology parameters in esophageal cancer patients. Methods:A total of 101 esophageal cancer patients without coagulation among preoperative plasma DD levels and postoperative pathology parameters in esophageal cancer patients who underwent radical operation between January 2009 to April 2010 were enrolled. The preoperative plasma DD levels, postoperative pathology T, N Grade, number of metastatic lymph nodes, tumor posi-tion, tumor length, and TNM stage were recorded. A statistic analysis of the above parameters was performed to reveal the correlation between plasma DD levels and tumor pathology features. Results:Preoperative plasma DD level has no correlation with Grade and tu-mor length, but shows positive correlation with pathology T, N status, and TNM stage, and has strong positive correlation with numbers of metastatic nodes. In addition, lower-third thoracic esophageal cancer patients have higher DD level than middle-third thoracic cases. Conclusion:Plasma DD level has a positive correlation with T stage, N stage, TNM stage, and number of positive lymph nodes. It also has important clinical significance.

Objective To detect the effect and mechanism of Cyr61 on the apoptosis of renal tissue caused by early stage of ischemic acute kidney injury (AKI). Methods 30 SD rats were randomized into 5 groups, including control group, AKI group, AKI+bicarbonate group, AKI+blank virus group, and AKI+over?expression Cyr61 virus group. After animal models were created for 2h, serum and renal tissue were collected from sacrificed animals. Expression level of TNF?α was determined by ELISA. HE staining was used to observe the histologic changes of renal tissues. The levels of NF?κB p65 and TNFR1 were measured by immunohistochemical method. RT?PCR and Western blotting assay were adopted to detect the mRNA and protein expression levels of NF?κB p65, TNFR1 and Caspase3. Results Compared with control group, AKI group, AKI+bicarbonate group, AKI+blank virus group, AKI+over?expression Cyr61 virus group had obvious kidney injury. The levels of TNF?α, the mRNA and protein expression levels of NF?κB p65, TNFR1 and caspase3 were markedly up?regulated. Over?expression of Cyr61 significantly attenuated the degree of pathological injury, numbers of apoptotic renal tubular epithelial cells and increased the degree of Scr. Although compared with other groups, the level of TNF?α in kidney tissue had no difference, there was obvious decreased protein level of NF?κB p65, while the increase of TNFR1 and Caspase3 protein was moderate. Conclusions During the early stage of AKI, over expression of Cyr61 could inhibit apoptosis, which may be related to the suppression of TNFR1 transcriptional expression and interference of TNF?αpathway. Its underlying mechanism therefore deserves further research.

Objective To investigate the role of p38MAPK in the differentiation of murine osteoblasts, and to observe the expressions of receptor activator of nuclear factor-κB ligand (RANKL) and osteoprotegerin (OPG). Methods The calvarial osteoblasts of newborn BALB/c mice were cultured in MEM medium containing 10% NCS. Raloxifene (10~(-7) mol/L) and 17β-estradiol (10~(-8) mol/L) were added respectively when cells reached 70%-80% confluence combined with or without 5 μmol/L SB202190, an inhibitor of p38MAPK. The osteoblasts alkaline phosphatase activity assays were performed 72 hours later using PNPP method, and mRNA levels of alkaliphosphatase (ALP), OPG and RANKL were determined by RT-PCR. Results 17β-estradiol and raloxifene increased ALP activity and ALP mRNA level in osteoblasts in vitro which were blocked by p38MAPK inhibitor.The mRNA levels of RANKL and OPG were up-regulated by 17β-estradiol and raloxifene while the ratio of OPG/RANKL kept constant. SB202190 (5 μmol/L) inhibited the highly expressed RANKL and OPG in osteoblasts, and obviously decreased the ratio of OPG/RANKL. Conclusions p38MAPK inhibition blocked the differentiation of osteoblasts and decreased the up-regulated OPG and RANKL expressions in osteoblasts significantly (P<0.05).

ObjectiveTo investigate the effect of SalB on bone marrow-derived mesenchymal stem cells (BMSCs) apoptosis induced by hypoxia and serum deprivation (hypoxia/SD) in the vitro. Methods BMSCs were cultured in the vitro and randomly divided into control group, hypoxia/SD group and SalB group.SalB group was composed by four groups and were pretreated by complete medium with 0.1、 1、 10、 100 mg/L SalB for 1 hour.
