1.PDIA3:a new therapeutic target of diseases
Chinese Journal of Pathophysiology 2015;(6):1145-1149
Protein disulfide isomerase A3 (PDIA3) is a member of protein disulphide isomerase family and widely exists in endoplasmic reticulum, cell surface, nucleus and mitochondria.PDIA3 promotes the glycoprotein folding and quality control in the endoplasmic reticulum and is also a key molecular of major histocompatibility complex class I mol-ecules assembly.In addition, PDIA3 is involved in the cell signal transduction and plays an important role in a variety of disease development.Therefore, this paper talks about the function of PDIA3, the relationship between disease and PDIA3 as well as its clinical outlook.
2.Advances in endostatin research
Chinese Journal of Pathophysiology 2000;0(07):-
Endostatin, a 20 kD (184 aa) C-teminal fragment of collagenⅩⅧ,is the most potent inhibitor of tumor angiogenesis described so for. Endostatin was initially isolated from a murine hemangioendothelioma cell line (EOMA). Purified recombinant murine endostatin generated in E.coli bacteria injected as unfolded suspension, inhibited the growth of a varity of metastatic and primary tumors in mice. However, its widespread application has been hampered by difficulties in the large-scale production of the antiangiogenic proteins. The limitation may be resolved by in vivo delivery and expression of the antitangiogenic gene. This review summarized the advances in endostain research in recent years including structure, the mechanism of generating ,function and therapy.

Salidroside is the most important bioactive component of Rhodiolae Crenulatae Radix et Rhizoma. Many recent studies have shown that salidroside plays an protective role in cardiovascular system by inhibiting myocardial cell death, promoting angiogenesis, improving heart function, inhibiting platelet aggregation, promoting body fat mobilization and cholesterol metabolism and other pharmacological effects. This article reviewed recent studies on pharmacological effects of salidroside on the cardiovascular system, providing references for the research and application of salidroside.

Objective To analyze and summarize the characteristics of thyroid diseases on the MR diffusion-weighted imaging.Methods Forty-two patients with thyroid lesions,including 10 males and 32 females [age range 20-72 years,mean age (42 + 13) years] underwent MR DWI before surgery and biopsy.The diagnoses of thyroid lesions were confirmed by pathological results.ADC values of benign and malignant nodules,with different b values (b values was 300,500 and 800 s/mm2),were generated by using post-processing software Functool of GE company(USA).The independent-samples t test was used and ROC curve was made to evaluate the diagnostic efficiency of the ADC values by using statistical software SPSS 12.0.Results Histologically,there were 28 benign lesions and 14 malignant lesions.Benign lesions included 20 cases of thyroid adenoma,6 cases of nodular goiter and 2 cases of Hashimoto's thyroiditis respectively.Malignant lesions consisted of 11cases of thyroid papillary carcinoma,2 cases of follicular thyroid cancer,and 1case of dysplasia.mean ADC value of benign thyroid lesions was (2.39 ±0.38) ×10 -3 mm2/s and mean ADC value of malignant thyroid lesions was ( 1.60 ± 0.56) × 10 -3 mm2/s with b value of 300 s/mm2.The statistical difference was significant between them( t =5.35,P < 0.05 ).The statistical difference of mean A DC values,between benign and malignant nodules with b value of 500 s/mm2 [ (1.85 +0.33 ) × 10 -3 mm2/s and ( 1.65 ± 0.42 ) × 10 -3 mm2/s ],was insignificant ( t =1.70,P > 0.05 ).The statistical difference of mean ADC values,between benign and malignant nodules with b value of 800 s/mm2 [ ( 1.61± 0.30) × 10 -3mm2/s and( 1.44 +0.29) × 10 -3mm2/s],was insignificant (t =1.76,P >0.05 ).ROC curve indicated that the ADC value of 1.98 × 10-3 mm2/s or higher was the cut-off value for differentiating benign from malignant cold thyroid nodules,with a sensitivity of 85.7%,and a specificity of 78.6%.Conclusions The image quality is best with b value of 300 s/mm2.Mean ADC value of benign lesions was significantly higher than mean ADC value of malignant lesions with b value of 300 s/mm2.

Objective To evaluate the efficacy of probiotics to treat irritable bowel syndrome (IBS).Methods Publications from database including PubMed,the Cochrane Library,Embase,CNKI,CBM and WanFang Data were searched up to August 31,2014.The randomized controlled trials (RCTs) on probiotics to treat IBS were eligible.The related articles were extracted and cross-checked independently by two reviewers.Methodological quality of trials was evaluated according to Cochrane Handbook 5.1.0 criteria.Meta-analysis was conducted using RevMan 5.2 software.Results A total of 17 RCTs involving 1 700 patients were included.Results of meta-analyses showed that compared with the placebo,probiotics was statistically better in improving the overall symptoms integral (SMD =-0.20,95% CI-0.33--0.07,P =0.002),alleviating abdominal pain/discomfort (SMD =-0.19,95% CI-0.29--0.09,P < 0.001),relieving abdominal distention (SMD =-0.16,95% CI-0.28--0.03,P =0.020),and defecation discomfort (SMD =-0.22,95% CI-0.42--0.02,P =0.030).There was no statistical significance in the overall quality of life (SMD =-0.08,95% CI-0.07-0.23,P =0.290) and adverse effect ratio (RR =1.08,95%CI0.79-1.49,P=0.630).Conclusion Probiotics have beneficial effects on IBS,which can improve the patients' symptoms and with less adverse reaction.Due to the bias,further large-scale,multicenter and high-quality RCTs are required to unify outcome indicators,further define sensitive strain,and standardize its usage,dosage and course of treatment.

Chinese Journal of Anesthesiology 2014;34(10):1204-1206
Objective To compare the clinical value of nerve stimulator-versus ultrasound-guided continuous femoral nerve block for analgesia after laparoscopic surgery.Methods Forty patients,aged 18-60 yr,with body mass index of 18-30 kg/m2,of ASA physical status Ⅰ or Ⅱ,scheduled for elective laparoscopic surgery,were randomly assigned into 2 groups (n =20 each) using a random number table:nerve stimulator group (group S) and ultrasound group (group U).Epidural anesthesia was performed with 1.73 % carbonated lidocaine in both groups.0.2% ropivacaine 5 ml/h was infused continuously after surgery to perform femoral nerve block for analgesia.VAS score at rest was assessed at 2,6,24 and 48 h after surgery.At 24 and 48 h after surgery,VAS scores during active and passive movement were assessed.The time for catheter placement near the femoral nerve and development of subcutaneous hematoma at the puncture site,local anesthetic intoxication and nausea and vomiting were recorded.The postoperative requirement for analgesics was also recorded.Results There was no significant difference in the VAS scores and puncture for femoral nerve block-and local anesthetics-related adverse events between the two groups.The time for catheter placement near the femoral nerve was 8.0 ± 1.4 and (6.7 ± 0.9) min in S and U groups,respectively,and the time was significantly longer in group S than in group U.No patients required rescue analgesic after surgery in both groups.Conclusion Nerve stimulator-guided continuous femoral nerve block provides higher clinical value than ultrasound-guided continuous femoral nerve block for analgesia after laparoscopic surgery and it is more suitable for clinical application.

Objective To investigate the influence of seawater immersion of open abdominal wound on function and pathological changes in liver in dog.Methods Twenty healthy dogs were divided randomly into two groups.A perforating abdominal wound was was made in each animal of both groups.Animals in control group(n=10)only abdominal wound was made,while abdominal wound was followed by seawater immersion in the animals of seawater immersion group(n=10).Blood samples were taken before the trauma(0 hour)and at 4,8,12,16 and 20 hours after the trauma and water immersion for both groups.Total bilirubin(TB),alanine transaminase(ALT),aspartate transaminase(AST),lactate dehydrogenase(LDH),blood ammonia(NH3),prothrombin time(PT),tumor necrosis factor-?(TNF-?),interleukin-6(IL-6)and endotoxin(ETX)were assayed.Experimental animals were sacrificed 24 hours after trauma,and the pathological changes in hepatic tissue were studied.Results TB,ALT,AST and PT were higher in seawater immersion group,than those in control group,with a marked elevation at 16 hours.In seawater immersion group,LDH was significantly higher than those in control group at 4 and 12 hours,and NH3 was increased significantly at 4 hours in experimental group(P
