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.

Objective To observe the effect of intensive scapular control training on pain, upper limb motor function and activities of daily living (ADL) in patients with post-stroke shoulder pain. Methods 58 patients with hemiplegia after stroke were randomly assigned into routine exercise group (group A, n=27) and intensive scapular control training group (group B, n=31). They were assessed with visual analogue scale for pain, simplified Fugl-Meyer Assessment and modified Bathel Index before and 8 weeks after treatment. Results All the assessment appeared better in group B than in group A after treatment (P<0.05). Conclusion Intensive scapular control training can promote the recovery of motor function and ADL, relieve the pain in patients with post-stroke shoulder pain.

OBJECTIVETo evaluate whether ultrasonic microbubble destruction (US/MB) could enhance the therapeutic effects of hepatocyte growth factor (HGF) gene transfer for acute myocardial infarction (MI).

METHODSMI was induced by left anterior descending artery ligation in male SD rats. Two to 4 hours thereafter, MI rats were randomly treated with tail vein infusing pc-DNA3.1-HGF plasmid mixed with microbubbles (US/MB-HGF group, n = 18); tail vein infusing pc-DNA3.1-HGF plasmid mixed with saline (US-HGF group, n = 18); tail vein infusing empty plasmid mixed with microbubbles (US/MB-P group, n = 18). All rats were exposed to ultrasound treatment thereafter till contrast imaging disappeared in cardiac region. Rats were sacrificed at 24 hours, 7 days or 14 days, respectively (n = 6 each) and myocardial protein expression of bcl-2 and HGF as well as microvascular density (MVD) were determined.

RESULTSThe myocardial protein expressions of bcl-2 and HGF in US/MB-HGF group were significantly higher than those in US-HGF and US/MB-P groups at 7 days post MI (all P < 0.01) and MVD was significantly higher in US/MB-HGF group (367.6 +/- 17.6) than that in US-HGF (268.9 +/- 0.8) and US/MB-P (186.8 +/- 11.8) groups (all P < 0.05) at 14 days post MI.

CONCLUSIONSUltrasound-mediated microbubble destruction could enhance systemic HGF administration induced myocardial angiogenesis and reduce systemic HGF administration induced myocardial apoptosis in rats with acute MI.

BACKGROUNDSevoflurane is currently used as a volatile inhalation anesthetic with many clinical advantages. A representative degradation product, compound A, was quantitatively measured to investigate whether there are different reactions between two kinds of water content sevoflurane formulations with different carbon dioxide (CO2) absorbents.

METHODSA closed-circle breathe bag with the Dräger Fabius GS anesthesia apparatus was used as an artificial rubber lung. The experiments were grouped according to different sevoflurane formulations: group A: higher-water sevoflurane (Ultane); group B: lower-water sevoflurane (Sevoness). During the experiment, CO2 (200 ml/min) was continually perfused to keep the end-tidal pressure of CO2 (P(ET)CO2) at 35 - 45 mmHg. The artificial ventilation was set to 6 L/min, and the breathing rate at 12 breaths/min. The circuit was operated with constant fresh gas flow rate (1 L/min) and the sevoflurane concentration was kept at 1.0 minimum alveolar concentration (MAC) for 240 minutes. At 0, 10, 20, 30, 60, 90, 120, 180 and 240 minutes, gas was collected from the Y-piece. Gas chromatography/mass spectrometry (GC/MS) was used to quantify the major degradation product, compound A, with different water content sevoflurane. PETCO2 and sevoflurane concentration, and the temperature of the canister were continuously monitored during the experiment.

RESULTSThere were no significant differences in P(ET)CO2 and sevoflurane concentrations between the two groups. Drägersorb 800 plus produced the highest concentrations of compound A compared with other sodalimes, and Sevoness in Drägersorb 800 plus generated more compound A than Ultane (P < 0.05). There were significant differences in the peak and average compound A concentrations between Ultane and Sevoness with Drägersorb 800 plus (P < 0.05), while the compound A concentration produced by Sodasorb grase and sofonolime in the two groups showed no significant difference (P > 0.05). In the same group, the peak and average of compound A concentration produced by Sodasorb grase and sofonolime showed significant difference with Drägersorb 800 plus (P < 0.05).

CONCLUSIONThe water content of sevoflurane and potassium hydroxide in CO2 absorbent can influence compound A production.

OBJECTIVETo investigate the expression of CXCR3 and its association with clinicopathologic features in breast carcinoma.

METHODSThe expression level of CXCR3 in 18 samples of breast cancer and corresponding normal tissues was investigated using reverse transcriptase-polymerase chain reaction (RT-PCR) and real-time RT-PCR analysis. Immunohistochemistry was carried out to examine the expression of CXCR3 in 80 breast cancers, 20 fibroadenomas and 15 normal breast tissues.

RESULTS(1) RT-PCR and real-time RT-PCR analysis showed a higher level of CXCR3 in breast cancer tissues than that in the corresponding normal breast tissues (P < 0.05). (2) Immunohistochemistry analysis showed that the positive rate of CXCR3 in breast cancer tissues was significantly higher than that in fibroadenomas and the normal breast tissues (P < 0.05). The expression level of CXCR3 in the lymph node-positive group was higher than that in the lymph node-negative group (P < 0.05). The expression of CXCR3 was positively correlated with the number of lymph nodes involved by metastasis, tumor size and pTNM tumor stage (P < 0.05).

CONCLUSIONSChemokine receptor CXCR3 was up-regulated in breast cancer, and was associated with the progression of breast cancer. CXCR3 might be a novel molecular marker to predict lymph node metastasis and prognosis of breast cancer.

OBJECTIVETo investigate genetic polymorphisms of 12 X chromosome short tandem repeat (X-STR) loci in ethnic Hebei Han population using an Investigator Argus X-12 amplification kit.

METHODSDNA was extracted for 198 unrelated individuals (96 males and 102 females) and amplified with a fluorescence labeled multiplex PCR system. PCR products were separated and genotyped with capillary array electrophoresis.

RESULTSOnly DXS10103 and DXS10101 showed significant linkage disequilibrium at the 12 X-STR loci. One hundred and forty-eight alleles, including 22 off-ladder (OL) alleles, were observed at the 12 X-STR loci in the population. The heterozygosity and polymorphic information content (PIC) were 0.5074-0.9143 and 0.4377-0.9079, respectively. The power of discrimination (PD) was 0.5074-0.9143 in males and 0.6876-0.9863 in females. The mean exclusion chance was 0.4377-0.9079 in the trios cases and 0.2984-0.8373 in the duo cases, respectively.

CONCLUSIONThe Investigator Argus X12 amplification system is highly polymorphic in ethnic Han population from Hebei and is useful for personal identification and paternity testing.

OBJECTIVETo observe the effect on intervention of sub-health with pestle needle (Chuzhen).

METHODRandomized controlled trail was adopted for this research. One hundred and fifty-three cases were randomly divided into two groups of a Chuzhen group (79 cases) and a massage group (74 cases). Acupoint of Bazhen (Baihui Bazhen, Shendao Bazhen, Zhiyang Bazhen, Mingmen Bazhen, Yaoyangguan Bazhen), Hechelu on the head, the neck and the lumbar area were adopted in Chuzhen group. While regular whole-body massage was applied in the massage group. The human sub-health score, the cornell medical index (CMI) and thermal texture maps system (TTM) technology of the two groups before and after the intervention were observed.

RESULTS1) After treatment, sub-health condition score, the CMI score, the M-R score and the TTM index were all increased in both groups (all P<0.01) 2) Comparison of D-value of the two groups before and after the intervention: the level of the sub-health score, the total score of CMI, and the index of sleep, pressure, Governor Vessel, Hukou (first web), blood lipid, viscosity of blood, microcirculation of TTM index of the Chuzhen group changed more obvious (all P<0.01), but there was no statistic significances in the M-R score and blood sugar of the TTM (both P>0.05). 3) The sub-health condition score in Chuzhen group was higher than that in the massage group (P<0.01).

CONCLUSIONChuzhen therapy has definite effect on intervention of sub-health, which is better than regular general massage.

Objective To explore the clinical significance and mechanisms of chromatin licensing and DNA repli-cation factor 1(CDT1)in lung adenocarcinoma).Methods The gene expression samples of lung adenocarcinoma tissue and normal lung tissue were downloaded from the TCGA database,and perform differential analysis,GO a-nalysis,independent prognosis analysis,and correlation analysis with immunotherapy using R language.CDT1 ex-pression in lung adenocarcinoma and normal tissues was detected by PCR in clinical samples.The changes of cell proliferation and cycle in si-CDT1 knockdown group and si-NC control group were detected by flow cytometry.The invasive ability of each group was detected by Transwell.The expressions of CDT1,TPX2 and p53 in each group were detected by Western blot.Results The TCGA data analysis revealed CDT1 as a differentially expressed gene.GO analysis indicated that CDT1 was closely associated with the cell cycle.The high expression of CDT1 in lung adenocarcinoma tissues was validated in clinical samples.CDT1 could serve as an independent factor for predicting the prognosis of lung adenocarcinoma and had predictive value for immunotherapy in lung adenocarcinoma.Knock-down of CDT1 resulted in a significant decrease in cell proliferation ability compared to the control group,and cells were noticeably arrested in the G1 phase.Transwell assay results demonstrated a significant reduction in invasive capacity in the CDT1 knockdown group.Knockdown of CDT1 led to a significant decrease in TPX2 expression and a significant increase in p53 expression,while overexpression of CDT1 yielded the opposite effect.Conclusion Re-sults demonstrate the elevated expression of CDT1 in lung adenocarcinoma,its association with prognostic signifi-cance,and its impact on lung adenocarcinoma's occurrence and development by influencing TPX2 and p53.

57 rubella virus strains were isolated using Vero cell line or Vero/SLAM cell line from patients' throat swabs during rubella outbreaks and sporadics in 10 provinces of China from 2003 to 2007. Fragments of 1107 nucleotides of E1 genes of the isolates were amplified by RT-PCR, the PCR products were directly sequenced and analyzed. The phylogenetic analysis based on 739 nucleotides showed that out of 57 Chinese rubella virus strains, 55 belong to a distinguish branch of 1E genotype when comparing with 1E genotype rubella strains from other countries, and the other 2 Chinese rubella virus strains belong to 2B genotype. Most of the nucleotide mutations of 57 rubella viruses were silent mutations, and the amino acid sequences were highly conserved. Except one amino acid change (Thr212 --> Ser212) in two rubella viruses at the hemagglutination inhibition and neutralization epitopes, there had no change found at the important antigenic epitope sites of the other rubella viruses. 1E genotype rubella viruses isolated from 10 provinces of China from 2003 to 2007, and two imported 2B genotype rubella viruses from Vietnam suggested that 1E genotype was the predominant genotype in this period of time. The rubella virus genotypes circulated during 2003 to 2007 were different from that circulating during 1979 to 1984 and 1999 to 2002, the rubella prevailed in recent years was mainly caused by 1E genotype rubella viruses with multi-transmission routes.
