ObjectiveTo investigate the affection of Shujinxi external granule on the knee joints function after meniscus suture.Methods60 patients who undertook meniscus suture were randomly recruited into two groups,30 cases in each group.The control group accepted conventional rehabilitation training,while the treatment group received Shujinxi external granule on the basis of the conventional rehabilitation training.Both groups were treated for two weeks for a therapeutic course,and statistics analysis was made after 3～4therapeutic courses.ResultsThe average postoperative knee activity after 8 weeks and 12 weeks was [ (114.1 ±18.6)° and [(129.6±10.3)° ],in thetreatment group,comparing to [(89.7±t2.5 )° and (112.7±16.6)° ]in the control group,the difference was statistically significant (P＜0.05).the IKDC score and the Lysholm score of treatment group after 12 weeks was [(84.76±5.21) and (92.54±3.22)],while the control group was [(79.63±4.67) and (85.61±4.92)],the difference was significant (P＜0.05).ConclusionShujinxi external granule can promote the recovery of knee joints function after the operation of meniscus suture.

Objective To evaluate the effects of postconditioning with enalapril on myocardial injury induced by hind limb ischemia-reperfusion (I/R) in rats.Methods Thirty-six healthy male Sprague-Dawley rats,weighing 200-250 g,were randomly divided into 3 groups (n =12 each):group sham operation (group S),group I/R and group enalapril postconditioning (group EP).Limb ischemia was induced by occlusion of bilateral hind limbs for 3 h followed by 3 h reperfusion in groups I/R and EP.At 30 min before reperfusion,enalapril 0.04 mg/kg was injected via the internal jugular vein in group EP,while the equal volume of normal saline was injected in groups S and I/R.The rats were sacrificed at 3 h of repeffusion and myocardial specimens were obtained for microscopic examination of pathologic changes and for determination of cell apoptosis,Bcl-2 and Bax protein expression,superoxide dismutase (SOD) activity and malondialdehyde (MDA) content in myocardial tissues.Apoptosis index was calculated.Results Compared with group S,apoptosis index and MDA content were significantly increased,Bax protein expression was up-regulated,Bcl-2 protein expression was down-regulated,and SOD activity was decreased in groups I/R and EP (P ＜ 0.05).Compared with group I/R,apoptosis index and MDA content were significantly decreased,Bax protein expression was down-regulated,Bcl-2 protein expression was up-regulated,and SOD activity was increased in group EP (P ＜ 0.05).The pathologic changes were significantly attenuated in group EP as compared with group I/R.Conclusion Enalapril postconditioning can attenuate myocardial injury induced by hind limb I/R in rats,and the mechanism may be related to reduction of apoptosis in cardiomyocytes and lipid peroxidation.

Objective:To analyze the mean levels of skeletal muscle mass and strength in elderly patients with type 2 diabetes mellitus(T2DM), and to investigate the effects of chronic inflammatory factors and oxidative stress on them.Methods:A cross-sectional study was conducted on 120 patients with T2DM aged over 60 years and 126 elderly patients without diabetes(the control group). Skeletal muscle mass, strength and serum levels of chronic inflammatory factors interleukin-6(IL-6), tumor necrosis factor-α(TNF-α)and 8-hydroxy-2′-deoxyguanosine(8-OHdG)were determined, and their effects on skeletal muscle mass and strength in elderly patients with T2DM were analyzed.Results:Compared with the control group, grip strength decreased in elderly patients with T2DM(25.03±7.85)kg vs.(29.52±7.73)kg( P<0.01), and skeletal muscle mass decreased(21.36±5.46)kg vs.(22.01±5.22)kg with no significant difference( P>0.05). Serum levels of 8-OHdG were higher in elderly patients with T2DM than in the control group(3.08±0.26)ng/L vs.(2.59±0.16)ng/L( P<0.01). Correlation and regression analysis results showed that 8-OHdG was an influencing factor for muscle strength in elderly patients with T2DM( R2=0.457)and that height and weight could be influencing factors for skeletal muscle mass in elderly patients with T2DM( R2=0.822). Conclusions:Skeletal muscle mass and strength decline in elderly T2DM patients, probably as a result of increased levels of oxidative stress.These findings may serve as evidence for sarcopenia intervention in elderly T2DM patients.

BACKGROUND:Studies have found that epithelial-mesenchymal transition is closely related with tumor invasion, metastasis, and drug resistance, but studies on the role of epithelial-mesenchymal transition in the transformation process of gastric cancer cels SGC7901 to gastric cancer stem-like cels are rarely reported.
OBJECTIVE: To explore the effect of epithelial-mesenchymal transition in the transformation process of gastric cancer cels SGC7901 to gastric cancer stem-like cels.
METHODS:Vincristine-induced SGC7901 cels were cultured and screened to prepare gastric cancer stem-like cels. CD44 phenotype, morphological changes, stem cel-related markers, and epithelial-mesenchymal transition related molecules were detected.
RESULTS AND CONCLUSION:After passage, vincristine-induced SGC7901 cels presented with morphological changes, and clonal cel spheres generated after serum-free suspension culture. Meanwhile, the proportion of SGC7901 cels positive for CD44 was decreased. Expression levels of SOX2, OCT4, Snail1 mRNA, Twist mRNA and Vimentin mRNA were significantly higher in the gastric cancer stem-like cels than SGC7901 cels, but the expression level of E-caderin was lower in the gastric cancer stem-like cels than SGC7901 cels. These findings indicate that gastric cancer cels SGC7901 can be successfuly transformed into gastric cancer stem-like cels, and the epithelial-mesenchymal transition is involved in this transforming progress.

Objective　To detect the genotypes and sequences of the exon 1 of human mannose-binding protein (MBP) allele in 5 Chinese nationalities. Methods　 The genotypes of MBP gene of 5 Chinese nationalities were detected by polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP). The exon 1 of the MBP gene of 22 Chinese Hans was analyzed by using ABI 310 genetic analyzer. Results　 The DNA sequences of exon 1 of Chinese MBP gene were acquired. The allele frequencies of the codon 54 of the MBP gene (MBP-54) of 5 Chinese nationalities were 0.181(Hans), 0.128(Uygurs), 0.181(Mongols), 0.179(Tibetans) and 0.181(Yis). The allele distribution for MBP-54 mutation of 5 Chinese nationalities was in good agreement with Hardy-Weinberg equilibrium. Compared with the Hans, Uygurs had a lower MBP-54 mutation rate. There were no differences in the allele frequencies between the chronic hepatitis B patients and health controls in Chinese Hans. The mutations of the codons 52 and 57 were not detected in this study. Conclusion　 A higher prevalence of MBP-54 mutation was found in 5 Chinese nationalities, MBP-54 mutation was not associated with the persistence of hepatitis B.

OBJECTIVETo study the relationship between expression of galectin-3 (Gal-3) and osteopontin (OPN) in occult metastasis in non-small cell lung cancer.

METHODSForty-six patients of non-small cell lung cancer (NSCLC) from January 2006 to October 2007 were selected. There were 28 males and 18 females, aged from 33 to 77 years old. The levels of lung tissues Gal-3 and OPN were detected by RT-PCR, and the levels of blood plasma's were measured by ELISA.

RESULTSThere were 12 patients who had metastasized. In un-metastasis group the Gal-3 and OPN mRNA expression levels were significantly lower than that in metastasis group: mean value were 0.07 +/- 0.17 and 0.17 +/- 0.25 in un-metastasis group, while 0.73 +/- 0.23 and 0.79 +/- 0.24 in metastasis group. Blood plasma levels of Gal-3 (18.8 +/- 7.9) microg/L and OPN (153.5 +/- 63.5) microg/L in NSCLC which were detected from metastasis group were higher than un-metastasis group of (9.2 +/- 5.6) microg/L and (89.2 +/- 24.0) microg/L.

CONCLUSIONSHigh serum levels of Gal-3 and OPN and high expression of Gal-3 and OPN mRNA in NSCLC are closely related to the occurrence and metastasis of NSCLC. They may be indexes of evaluating the occult metastasis in NSCLC.

Objective:To construct an effective survival nomogram for patients with clear cell renal cell carcinoma (ccRCC) using a large sample sized Chinese dataset, which can be used to predict individual 3- and 5-year overall survival (OS) precisely.Methods:The data of 672 ccRCC patients received operation diagnosed at Xijing Hospital from January 2012 to December 2016 were retrospectively analyzed. There were 467 males and 205 females. Their median age was 56 years old (ranging 23-83 years old). There were 327 patients with tumor on the left kidney and 345 patients with tumor on the right kidney. Clinical stageⅠ, Ⅱ, Ⅲ, Ⅳ were 584, 47, 19 and 22 cases, respectively. At the time of diagnosis, 504 patients were asymptomatic and 168 patients were symptomatic. Preoperative alkaline phosphatase was 80 (41-240) U/L. Preoperative serum albumin was 44.8 (30.5-59.8) g/L. Preoperative neutrophil absolute value/lymphocyte absolute value (NLR) was 2.25 (0.81-9.89). Preoperative platelet count was 205 (82-589)×10 9/L. Preoperative creatinine was 97 (55-230) μmol/L. Radical nephrectomy was performed in 420 (62.5%) patients and partial nephrectomy was performed in 252 patients. Cox multivariate analysis was used to determine the independent predictors of the postoperative OS. Then, the nomogram was constructed using R software, which integrates all independent predictors according to the coefficients in the multivariate analysis. Moreover, the performance of the nomogram was evaluated using the consistency index (C-index) and the calibration plots. Results:Cox multivariate analysis results showed that age at diagnosis ( P<0.001), clinical TNM stage ( P<0.001), preoperative NLR ( P=0.012), preoperative alkaline phosphatase ( P=0.002) and preoperative albumin ( P<0.001) were the independent predictors of postoperative OS in ccRCC patients. The nomogram established by integrating these five factors had a good discriminatory ability (C-index=0.819, 95% CI 0.813-0.825), and the calibration plots showed that excellent agreements between the nomogram prediction and the actual observation were achieved. Conclusions:Based on a large sample sized Chinese dataset, this study established an effective survival model for patients with ccRCC and good performance of the nomogram was demonstrated by internal validation. Our nomogram can help urologists to predict individual 3- and 5-year OS accurately for Chinese ccRCC patients.
