BACKGROUND: There is nearly no muscle tissue with satisfactory function and appearance applying in clinical repair and construction of injured muscles to date. OBJECTIVE: To investigate the feasibility of applying autologous fascia as a scaffold to construct muscle in vivo. DESIGN, TIME AND SETTING: The randomized, self-matched control experiment was carried out between January 2004and June 2006 at Department of Burns & Plastic Surgery, Second Hospital of Shenzhen, Shenzhen, Guangdong Province, China MATERIALS: Twenty-eight healthy New Zealand rabbits, weighing (1.7±0.5) kg, without sex restriction, establishing middle part defect model of anterior tibial muscle of rabbit hind legs. METHODS: One hind leg of each rabbit was randomized to the experimental group (n=28), the other hind leg was assigned to one of 3 control groups, scaffold-connected group (n=10), muscle particle implant group (n=10) and blank control group(n=8). In experimental group, the defect was connected with an autologous fascial scaffold and filled with the mutilated muscle particles, and subcutaneous tissue and skin were sutured in situ. In scaffold-connected group, the treatments were same to the experimental group only except muscle particle implantation. In muscle particle implant group, the defect was filled with muscle particles but without fascial scaffold and other treatments were same to the experimental group. The defect in blank control group received no treatment. MAIN OUTCOME MEASURES: The success rate of muscle transplantation, histological and ultra structural observation,and immunohistochemical identification of desmin were observed at 2, 3, 4, 6 and 9 weeks after operation. The middle parts of samples were also harvested for relative quantitative analysis of α-actin cDNA using reverse transcription-polymerase chain reaction in the experimental group and scaffold-connected group.RESULTS: In experimental group, 1 muscle broke near the proximal junction, the other 27 succeeded and the appearance of healed defects became near normal gradually. In scaffold-connected group, 4 muscles broke, 6 muscles still depressed in defect area; in muscle particle implant group and blank control group, the defects had no change. In experimental group, a large quantity of skeletal muscle satellite cells proliferated, which reached peak at 2-3 weeks, cells attached to the ends of fibrous connective tissue; in scaffold-connected group only fibrous connective tissue was seen. lmmunohistochemistry showed that 85% cells in experimental group were desmin-positive, while the positive rate in scaffold-connected group was < 25%. The relative quantitative analysis of α -actin cDNA showed that there were significant differences between the experimental group and scaffold-connected group at different time points(P < 0.05).CONCLUSION: The success rate of repairing muscle defect with autologous fascial scaffold reached 93.33%, which indicates that it is feasible to promote muscle regeneration with autologous fascial scaffold.

OBJECTIVETo investigate the differences between clinicopathological features and prognosis of alpha-fetoprotein (AFP) negative (AFP < 20 ng/ml) and positive (AFP ≥ 20 ng/ml) hepatocellular carcinoma (HCC) patients.

METHODSClinicopathological data of 142 AFP-negative and 109 AFP-positive HCC patients who underwent RO radical hepatectomy in the Cancer Hospital of Chinese Academy of Medical Sciences between January 2006 and December 2011 were retrospectively reviewed and analyzed in this study.

RESULTSCompared with the AFP-negative patients, a higher female to male sex ratio, the later Barcelona Clinic Liver Cancer ( BCLC) stage, more liver capsule invasion and poorer Edmondson-Steiner grade were in the AFP-positive cases (P < 0.05 for all). Furthermore, the 1-, 3-, and 5- year overall survival rates were 94.4%, 82.4% and 61.0% in the AFP-negative group and 87.2%, 61.1% and 40.2%, respectively, in the AFP-positive group (P < 0.001). The multivariate analysis with Cox's proportional hazards model showed that AFP status, tumor size and Edmondson-Steiner grade are independent risk factors for survival of all the patients (P < 0.05) , and large tumor and Edmondson-Steiner grades III/IV are independent risk factors for worse survival in AFP-negative patients (P < 0.05). However, large tumor diameter was proved to be an independent risk factor leading to poor prognosis of AFP-positive cases (P < 0.05).

CONCLUSIONHigh levels of AFP indicate that the tumors are more malignant and with unfavorable prognosis.

Objective:To investigate the effects of body mass index (BMI) on lung function in patients with chronic obstructive pulmonary disease (COPD).Methods:A total of 3 312 patients with COPD were selected from outpatients and inpatients in Department of Gerontal Respiratory Medicine of the First Hospital of Lanzhou University from August 2016 to August 2020, including 1 103 patients in stable period and 2 209 patients in acute exacerbation period. According to body mass index (BMI), these COPD patients were divided into four groups: low weight (56 cases, 131 cases), normal weight (448 cases, 945 cases), overweight (424 cases, 773 cases) and obesity groups (175 cases, 360 cases) respectively in stable stage and in acute exacerbation stage. The lung function of inspiratory capacity (IC), vital capacity (VC), residual volume (RV)/total lung capacity (TLC), forced expiratory volume in 1 second (FEV 1), forced vital capacity (FVC), FEV 1/FVC, maximal mid-expiratory flow (MMEF), diffusing capacity of the lung for carbon monoxide (DLCO), DLCO normalized per liter alveolar volume (DLCO/VA), respiratory impedance (Zrs), respiratory resistance at 5 Hz (R5), respiratory resistance at 20 Hz (R20) and respiratory reactance at 5 Hz (X5) were measured using MasterScreen PFT in all patients, and the influence of BMI on lung function was analyzed respectively. The risk factors of impaired lung function were analyzed by ordered logistic regression with lung function grade as dependent variable and age, gender, smoking history, smoking index and BMI as independent variables (“%pred”represents the percentage of predicted value). Results:The proportion of patients with lung function grade Ⅲ/Ⅳ in acute exacerbation period (64.9%, 37%, 27.4%, 24.4%) was higher than that in stable stage (42.9%, 25.9%, 13.7%, 9.1%), while the proportion of patients with lung function grade Ⅰ in stable stage (21.4%, 34.2%, 38.2%, 40.0%) was higher than that in acute exacerbation period (7.6%, 20.0%, 25.4%, 22.8%) (all P<0.05). The IC%pred, VC%pred, FEV 1%pred, FVC%pred, FEV 1/FVC, MMEF%pred, DLCO%pred, DLCO/VA%pred and R20 in low weight group were significantly lower than other groups both in stable period and acute exacerbation period (all P<0.05). The RV/TLC was higher in low weight group than that of normal weight and overweight groups in both periods (all P<0.05). The IC%pred, FEV 1%pred, FEV 1/FVC, DLCO%pred, DLCO/VA%pred, R5 and R20 in overweight and obesity groups were higher than those of normal weight group (all P<0.05). The RV/TLC, FEV 1/FVC, DLCO%pred, DLCO/VA%pred, Zrs, R5 and R20 in obesity group were higher than those of overweight group (all P<0.05). The ordered logistic regression analysis showed that low weight was independent risk factor for impaired lung function of COPD both in stable period [ OR (95% CI) 2.316 (1.206-3.554)] and acute exacerbation period [ OR (95% CI): 2.457 (1.647-3.669)]. Conclusion:Lower BMI has an adverse effect on lung function, and it is an independent risk factor for impaired lung function in COPD patients.

Abstract: To develop novel live attenuated influenza vaccine, we explored the feasibility to attenuate influenza virus by codon deoptimization of NS1. According to the codon usage bias in influenza A virus, we designed and synthesized a condon-deoptimized NS gene by substituting codons of 110 amino acids in the NS1 gene of A/Puerto Rico/8/34(H1N1) with unpreferred synonymous codons. The influenza A virus with the codon deoptimized NS1 gene (deoNS virus) was rescued by reverse genetics. Plaque forming assay and virus growth curve showed that the growth of deoNS virus was reduced about 1000 times in MDCK cells compared to that of the wild-type virus. Intranasal inoculation with deoNS virus did not cause death or evident disease in infected BALB/c mice. Furthermore, the virus titer in the lungs of mice infected with deoNS virus was significantly lower (i.e. 100-1000 times) than that of wild-type virus. Our results indicated that influenza virus could be effectively attenuated by synonymous codon deoptimization of NS1 gene. This strategy will be useful to develop new attenuated candidates for the production of live attenuated influenza vaccines.
