Objective To detect the salivary levels of IgA,alpha-amylase and acetylcholinesterase (AChE) and saliva flow rates of IgA in normal controls versus Parkinson disease (PD) patients,and to analyze the correlation of these salivary biochemical indexes with disease duration,H&Y rating scale,SCOPA-AUT score,sialorrhea score,dry mouth score and the use of levodopa.Methods Thirty-eight PD patients including twenty-two patients treated with levodopa,and twenty-one normal controls were selected in our study.About 3 ml saliva was collected from each subject.Salivary IgA was detected by immunoturbidimetry.Alpha-amylase and AChE were tested by enzymatic colorimetry.The protein concentration was analyzed by BCA kit to normalize ACHE.The salivary flow rate and IgA flow rate were also calculated.Results Salivary flow rate (ml/min) was (0.39±0.22) in normal controls,and (0.35±0.28) in PD groups;the level of IgA (mg/L) was (148.3±86.1) in normal controls,and (183.7±126.3) in PD groups;IgA flow rate (μg/min) was (47.8±25.9) in normal controls,and (46.9±27.1) in PD groups;the level of alpha-amylase (U/L) was (1.63 ± 1.21) × 105 in normal control,and (1.35 ± 9.87) × 105 U/L in PD group;and the level of AChE (U/mg) was (0.12±0.08) in normal controls,and (0.09±0.05) in PD group.No statistically significant differences in above indexes were found between PD group and controls.There were negative correlations between salivary flow rate and dry mouth score (r =-0.445,P =0.005) and between alpha-amylase concentration and sialorrhea score (r=-0.327,P=0.045).The positive associations were found between IgA concentration and the SCOPA-AUT score (r =0.438,P =0.006),and between IgA flow rate and sialorrhea score (r =0.411,P =0.01).Conclusions Salivary flow rate and level of alpha-amylases tend to be decreased in PD patients,while IgA concentration has an upward tendency.Salivary alpha-amylases concentration and IgA flow rate are correlated with the symptom of sialorrhea,while IgA concentration correlates with the degree of autonomic symptoms.These measurements can be used as indexes for evaluating the lesions of the autonomic nervous system.

Splenic cyst is clinically rare.It can be classified as either true or false.Ultrasound,CT and MRI scan are helpful in diagnosing splenic cyst.Indication for a treatment depends mainly on clinical symptoms and diameter of the cyst.Now,there is a more conservative attitude on splenic surgery and the patient should be offered laparoscopic approach.Both nonoperatively treated patients and surgically treated patients should be given ultrasound examination regularly,in order to check the cyst size and exclude reappearance.

Objective The relationship between the clinicopathological features and the prognosis of breast cancer patients was evaluated by the expression of EPB41L4A-AS2 in breast cancer tissues.Methods The relationship between the expression of EPB41L4A-AS2 and the clinical features of breast cancer was evaluated by using the genome meta analysis,TCGA and Gene Expression Library(GEO) datasets.The correlation between EPB41L4A-AS2 and apoptotic pathway was verified by Western blotting.Results The results from Meta -analysis,TCGA and GEO datasets showed that EPB41L4A-AS2 was low in breast cancer tissues and was positively correlated with poor clinical and pathological features.EPB41L4A-AS2 was confirmed an association with the classical apoptosis pathway in breast cancer cell lines.In the meta-analysis of GEO,we found the high expression of EPB41L4A-AS2 with good prognosis.Conclusion EPB41L4A-AS2 inhibits tumor formation and has a high value in clinical prognosis of breast cancer.

Cancer cells display a decreased mitochondrial respiration along with an abnormal activation of glycolysis to satisfy the demand of the malignant growth even in the presence of oxygen.This phenomenon may be caused by mitochondrial dysfunction,hypoxia of microenvironment and the abnormal activation of upstream regulators of glycolysis pathway.Treatment targeted at the glycolysis pathway and its upstream regulators may provide a new therapeutic strategy of cancer.

Objective A meta-analysis was conducted to figure out the effects of anesthetic methods on postoperative myocardial infarction in noncardiac surgery patients.Methods We searched PubMed, Embase, Ovid, Cochrane Library, Google scholar, CNKI, Wang-fang data and VIP Database (by September 2016) to identify relevant studies that focused on the effect of intrathecal blockade on postoperative myocardial infarction and mortality in non-cardiac surgery.Meta-analysis was performed using software of RevMan 5.3.Results A total of 21 859 patients from 10 RCTs were enrolled.The meta-analysis showed that there were no differences in myocardial infarction within 7 postoperative days (OR=0.44, 95%CI 0.13-1.46, P=0.18) or 30 days (OR=1.49, 95%CI 0.89-2.49, P=0.13) and all-cause mortality (OR=1.26, 95%CI 0.84-1.88, P=0.26) between epidural anesthesia combined with general anesthesia and general anesthesia.Furthermore, there were no differences in myocardial infarction within postoperative 7 days (OR=1.14, 95%CI 0.31-4.17, P=0.84) and all-cause mortality within postoperative 30 days (OR=0.88, 95%CI 0.43-1.79, P=0.73) between spinal anesthesia alone and general anesthesia alone.Conclusion Intrathecal blockade cannot affect the incidence of myocardial infarction and mortality in high-risk cardiac patients undergoing intermediate or high-risk non-cardiac surgery.

OBJECTIVE:To evaluate the clinical outcome of arterial perfusion with chemotherapy medicine together with elemenum emulsion injection solution via Port-Catheter System(PCS)in treating middle-late malignant tumors.METHODS:A total of63patients with middle-late malignant tumors were enrolled,31were randomly assigned to receive arterial perfusion of chemotherapeutics in combination with elemenum emulsion(group A),and32cases to receive single arterial perfusion of chemotherapeutics(group B),the short-term curative effects of the2groups were then compared.RESULTS:The total effec_ tive rate of group A and B were66.7%and46.7%,respectively with one-year survival of which respectively at56.7%and43.3%.There was significant difference between two groups(P

Objective To evaluate the safety and efficacy of nephron sparing surgery (NSS) for renal angiomyolipoma (RAML). Methods Thirty-nine patients of RAML were underwent NSS. Tumor enucleation was done in 23, partial nephrectomy in 16, and selective arterial embolization in 2. Results The average diameter of enucleated tumor was 5.8 cm(from 3.0 to 14.0 cm), the average of blood loss was 190 ml(from 75 to 800 ml),none of the patients developed hemorrhage or urinary fistula. The average follow-up of 38 patients was 48 months(from 1 to 120 months). Postoperative serum level of creatinine was stable, no patients had a local recurrence. Conclusions NSS can be performed with satisfactory result in RAML. Effective control of hemorrhage and conservancy of renal function are the key points.
