OBJECTIVETo observe the therapeutic effect of acupuncture on gastrointestinal dysmotility in liver cirrhosis.

METHODSForty cases of gastrointestinal dysmotility in liver cirrhosis were randomized into an acupuncture group and a motilium group, 20 cases in each one. In the acupuncture group, on the basis of the conventional treatment, electroacupuncture was applied at Zusanli (ST 36), Sanyinjiao (SP 6) and Taichong (LR 3) for 30 min, once a day. In the motilium group, on the basis of the conventional treatment, motilium was taken orally 30 min before meals, 10 mg each time, three times a day. The treatment was required for 2 weeks in both groups. The changes in the digestive tract symptom score and liver function Child-Pugh score were observed and the efficacy was assessed.

RESULTSThe total effective rate of digestive tract symptoms was 85.0% (17/20) in the acupuncture group and 70.0% (14/20) in the motilium group. The score improvements in abdominal distention, belching and vomiting in the acupuncture group were superior to those in the motilium group (all P < 0.05). In the acupuncture group, the liver function Child-Pugh total score was 8.40 +/- 0.22 before treatment and reduced to 5.36 +/- 0.17 after treatment, in which the scores for ascites, serum bilirubin and albumin were all reduced (all P < 0.05) and the reducing range was increased in tendency with the improvements in digestive tract symptoms. In the motilium group, Child-Pugh score was not changed obviously as compared with that before treatment. CONCLUSION Acupuncture effectively alleviates digestive tract symptoms and improves liver function for the patients of liver cirrhosis, its efficacy on gastrointestinal dysmotility in liver cirrhosis is superior to motilium.

OBJECTIVETo investigate whether FTY720 inhibits rat mesangial proliferation and extracellular matrix expansion through suppression of transforming growth factor β1-connective tissue growth factor (TGFβ1-CTGF) pathway, and to explore experimental evidence for its effect on mesangial proliferative glomerulonephritis.

METHODSA rat model of anti-Thy-1 mesangial proliferative glomerulonephritis was established and FTY720 intervention was performed. Periphery blood lymphocyte count, urine protein excretion, glomerular mesangial proliferation, protein and gene expression of TGFβ1 and CTGF and extracellular matrix protein including fibronectin, laminin and collagen IV in isolated glomeruli were documented at 1, 3 and 7 days after injection of anti-Thy-1 antibody.

RESULTSThe model group developed proteinuria at 1, 3 and 7 days after injection of anti-Thy-1 antibody, which were significantly higher [(27.9 ± 7.3), (63.5 ± 18.8) and (52.4 ± 15.4)mg/d, respectively] than those in the control group [(8.4 ± 2.4), (8.4 ± 2.1) and (10.4 ± 3.2) mg/d; respectively, P < 0.01]. FTY720 intervention group showed significantly decreased proteinuria at 3 and 7 days after injection [(31.4 ± 7.0), (25.5 ± 7.7) mg/d, respectively] than model group (P < 0.01), although higher than the control group (P < 0.01). After intervention for 3 and 7 days, FTY720 significantly down-regulated both TGFβ1 and CTGF gene and protein expression in cultured glomeruli, and suppressed the production of glomerular extracellular matrix protein secretion, leading to attenuated mesangial cell proliferation and extracellular matrix expansion in rat anti-Thy-1 mesangial proliferative glomerulonephritis.

CONCLUSIONFTY720 significantly attenuates mesangial proliferation and extracellular matrix expansion through inhibition of TGFβ1-CTGF pathway in rat, and thus ameliorates the development of anti-Thy-1 mesangial proliferative glomerulonephritis.

OBJECTIVETo investigate the anatomical study and clinical applications of sural neuron-myocutaneous flap transposition for repairing the special patients with soft tissue defect in foot and ankle.

METHODSThe branches, distributions and anastomoses of the vessels and nerves lie in superficial layer of the posterior crural region were observed on 30 sides of adult cadaver lower limb specimens perfused with red latex. Since February 2004, distally based sural neuron-myocutaneous flap was applied for repairing 7 cases of soft tissue defect in foot and ankle.

RESULTSThe nutrient vessels of sural nerve, small saphenous vein and posterior femoral cutaneous nerve anastomosed permanently with the musculocutaneous perforators of medial and lateral head of gastrocnemius. There were 2 - 3 anastomoses found respectively. The musculocutaneous perforators pierced the two heads of gastrocnemius muscle (1.8 +/- 0.5) cm medially and (3.7 +/- 0.9) cm laterally away from the groove of the muscle. The medial anastomoses more closed to the middle groove and their diameters were found larger than the lateral ones. In operation, we routinely observed the compound flap for 15 to 20 minutes and found actively errhysis on the muscle, so the fine blood circulation in the flap was demonstrated. All flap survived after operation and the cases were followed up 2 to 6 months with cured osteomyelitis and satisfied flap outline.

CONCLUSIONSDistally based sural neuro-myocutaneous flap can live. The operative method is simple. The flap offers an excellent donor site for repairing the soft tissue defect in foot and ankle in special cases.

OBJECTIVETo investigate Chinese medicine (CM) patterns and epidemiological characters of patients with influenza-like illness (ILI) syndromes in clinics in China.

METHODSA prospective multi-center observational epidemiology survey on the clinical CM patterns of ILI and its prevalence was conducted from September 2009 to April 2010. A unified survey questionnaire was developed for data collection of ILI symptoms and CM patterns. Totally 45 hospitals from 22 provinces, municipality cities and autonomous regions of China participated this study. The collected data were input by EPI-data v3.1 and analyzed by SPSS 18.0, which included descriptive analysis and Chi-square test for group comparison.

RESULTSA total of 5,967 ILI patients were included in the study. The proportion of the 18-34 aged group (56.2%) was the largest; students (41.0%) were more than other occupations. Majority of the patients had the wind-heat invading Lung (Fei) syndrome (76%), while in Southwest China mainly wind-heat invading Lung syndrome and wind-cold tightening the exterior syndrome occurred. The typical symptoms of ILI were ranked as fatigue (80.9%), cough (72.2%), sore throat (67.2%), muscular soreness (67.1%), headache (65.4%), aversion to cold (60.1%), thirst (55.1%) and nasal obstruction (48.1%).

CONCLUSIONSThe ILI patients in clinics were mainly teenagers and young adults. In regard to CM syndrome, wind-heat invading Lung syndrome prevailed in all regions except the Southwest China. The characteristics of CM syndrome of ILI patients may be relevant to age and region distribution.

OBJECTIVETo construct an cell penetrating peptide-based expression vector capable of targeted delivery of proteins into the cell nuclei and study its function of protein transduction.

METHODSThe fusion protein expression vector pET14b-HC(L)NE (pET14-b-His-CPP-Linker-NLS-EGFP) incorporating cell penetrating peptide (CPP), nuclear localization signal(NLS), linker and enhanced green fluorescent protein (EGFP) was constructed based on His-tagged pET14b-HE (pET14b-His-EGFP) by site-directed mutagenesis PCR method. After identification by enzyme digestion and DNA sequencing, the recombinant plasmid was transformed into BL21(DE(3)) strain. The HC(L)NE fusion protein was expressed following IPTG induction and purified with Ni(2+)-NTA affinity chromatography. After dialysis and filtration, the HC(L)NE fusion protein was added into cultured eukaryotic cells. The protein transduction in the living cells was observed under fluorescence microscope and analyzed by Western blotting.

RESULTSEnzyme digestion and DNA sequencing confirmed successful construction of the pET14b-HC(L)NE vector, and the fusion protein efficiently expressed in E. coli. Protein transduction experiments in eukaryotic cells revealed that the fusion protein could rapidly penetrate the cell membrane and reach the cell nucleus, and this internalization was time- and concentration-dependent.

CONCLUSIONThe cell penetrating peptide-based expression vector for targeted protein delivery to the cell nucleus has been successfully constructed, and a transport system that can delivery exogenous proteins or polypeptides into the cytoplasm and cell nucleus is established, which provides an economical and efficient means for functional study of the proteins and polypeptide in cells and targeted drug delivery.

OBJECTIVETo analyze the effectiveness of Chinese medicine and integrated Chinese and Western medicine for influenza A (H1N1) in the fever clinics and its relevant expenditure.

METHODSA prospective survey on the clinical epidemic observation and follow-up was conducted from July 2009 to October 2009 with a self-developed questionnaire whose contents including the clinical data of the confirmed 149 H1N1 cases and their relevant therapeutic expenditure. The patients were assigned to the Chinese medicine group (22 cases treated by Chinese medicine alone) and integrative medicine group (124 cases treated by both Chinese medicine and Western medicine). The data were processed with descriptive analysis, t test and χ (2), and sum-rank test.

RESULTSThe proportion of clinical recovery of Chinese medicine group (81.8%) was higher than that of integrative medicine group (54.8%) with statistical significance (P=0.02). The average fever durations in both groups were 3.5 to 4 days, showing no significant difference (P=0.86). In the comparisons of average cost of Chinese herbs, drugs, therapies, and total cost, those of the Chinese medicine group were lower than those in the integrative group (P=0.01, P=0.00, P=0.00, P=0.00).

CONCLUSIONSThe H1N1 patients in the fever clinic who received Chinese medicine treatment had a higher clinical recovery proportion than those who received integrated Chinese and Western medicine treatment with lower medical cost. However, due to small sample size of the Chinese medicine group in the study, the conclusion needs further confirmation by studies with large sample size.
