Objective To observe the efficacy and adverse effects of conventionally fractionated (CF) versus hypofractionated (HF) three-dimensional conformal radiotherapy (3DCRT) for hepatocellular carcinoma (HCC) with portal vein tumor thrombosis.Methods A retrospective analysis was performed on the clinical data of 65 patients with HCC suitable for 3DCRT from 2008 to 2012.These patients were randomly divided into HF group (n =32) and CF group (n =32).The HF group received 3DCRT at a total dose of 45-55 Gy (3-4 Gy/fraction,3-5 fractions/week),while the CF group at a total dose of 40-56 Gy (2 Gy/fraction,5 fractions/week).Results The follow-up rate was 100％.For the HF group and CF group,the short-term response rates were 72％ vs.55％ (P =0.034),the 1-year local control rates were 72％ vs.55％ (P=0.034),the 1-year overall survival rates were 59％ vs.45％ (P=0.042),and the numbers of individuals with grade 1-2 acute gastrointestinal reactions,deterioration of liver function,and radiation hepatitis were 14 vs.11,8 vs.8,and 1 vs.0,respectively (P =0.237).Conclusions HF 3DCRT is superior to CF 3DCRT in the treatment of HCC.

Objective:To investigate the efficacy and safety of plasma exchange (PE) combined with plasma perfusion (PP) in treatment of liver failure and the influence on inflammatory factors and liver function.Methods:98 patients with liver failure in our hospital from February 2014 to February 2016 were selected as the subjectswere,and they were randomly divided into experimental group and control group,and each group was 49 cases.The experimental group was treated with PE combined with PP,and the control group was received PE alone.The liver function before and after treatment was detected by automatic biochemical analyzer.The serum levels of C-reactive protein (CRP),tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) were determined by enzyme-linked immunosorbent assay (ELISA).The total effective rate,the incidence of side effects,the levels of liver function and inflammatory factors before and after treatment were compared between the two groups.Results:The clinical effective rate in the experimental group (91.84％) was significantly higher than that in the control group (73.47％),the difference was statistically significant (P＜0.05).The incidence of adverse reactions in the experimental group (10.20％) was significantly lower than that in the control group (38.78％),the difference was statistically significant (P＜0.05).The levels of serum alanine aminotransferase (ALT),total bilirubin (TBIL) and blood ammonia (NH3) were significantly decreased in both groups after treatment (all P＜0.05).Albumin (ALB) and thrombin activity (PTA) were significantly increased in both groups after treatment (both P＜0.05).After treatment,the serum levels of ALT,TBIL and NH3 in the experimental group were lower than those in the control group (all P＜0.05),the levels of ALB and PTA were higher than those of the control group,the difference was statistically significant (both P＜0.05).After treatment,the serum levels ofCRP,TNF-α and IL-6 were lower than those before treatment,and the serum levels of CRP,TNF-α and IL-6 in the experimental group were lower than those in the control group (all P＜0.05).Conclusion:The combination of plasma exchange and plasma perfusion has a good effect in the treatment of liver failure,and the incidence of adverse reactions is low.It can effectively remove inflammatory factors,improve liver function and improve the quality of life of patients.

Objective To investigate the characteristics of plaque morphology of the patients with unstable angina(UA)by intravascular ultrasound(IVUS). Methods24 patients with stable angina pectoris(SA)and 33 patients with unstable angina(UA)were examined by coronary coronary arteriograph(CAG)and intravascular ultrasound(IVUS).The culprit lesions about the characteristic of the plaque were studied,the external elastic membrane cross-sectional area and lumen cross-sectional area were measured,the plaque area,plaque burden,eccentricity index were calculated,and the remodeling index was examined. ResultsExternal elastic membrane area,plaque area and vascular remodeling ratio were significantly greater at target lesions in UA patients than in patients with SA(P＜0.05).Positive remodeling and soft plaque were predominantly in UA patients(P＜0.05). ConclusionThe morphological features of coronary artery plaques in UA group were significantly different from those in SA group.More soft plaque,plaque rupture,thrombus formation,and positive remodeling were found in UA patients compared with SA patients.

OBJECTIVEThis work investigated mesenchymal stem cells (MSCs) modified with Runt-related transcription factor 2 (Runx2) therapy for bone regeneration in rabbit mandibular distraction osteogenesis.

METHODSForty-eight New Zealand mature white rabbits were randomly divided into three groups after the rabbit model of mandibular distraction osteogenesis was established: reconstruction plasmid modified with Runx2 (group A), plasmid without Runx2 (group B), and the same dose of saline as control (group C). At the fifth day of distraction phase, MSCs with reconstruction plasmid modified with adv-hRunx2-gfp were injected into the distraction gap of group A. MSCs with reconstruction plasmid modified with adv-gfp was injected into the distraction gap of group B, whereas group C was injected with the same dose of saline. At 8 weeks after injection, all animals were sacrificed, and the distracted mandibles were harvested. The general imaging histological observation and three-point bending test were used for evaluation.

RESULTSCT plain scan and histological analysis confirmed that the amount of new bone forming in the distraction gap of group A was significantly higher than those in groups B and C. Dual-energy X ray and three-point bending test results also showed that the bone mineral density, bone mineral content, and maximum load of the distraction gap of group A were significantly higher than those of groups B and C (P<0.01).

CONCLUSIONRunx2-ex vivo gene therapy based on MSCs can effectively promote the bone regeneration in rabbit mandibular distraction osteogenesis and shorten the stationary phase. Therefore, reconstruction of craniofacial fracture would be a valuable strategy

Objective To observe the difference between skeletal age of hand and wrist and chronological age and explore the reliability of CHN radiographic atlas method to assess the skeletal age of hand and wrist in children and adolescent.Methods Total 1397 healthy children (666 boys,731 girls;age range,1.0-18.0 years old) with hand and wrist injury from 2007 to 2011 were selected.Forty groups (n =20 for boys and girls,respectively) were classified according to CHN radiographic atlas method.The radiographs of hand and wrist were assessed by CHN radiographic atlas method,the relations between skeletal age and chronological age were investigated by using Wilcoxon signed ranks test.Results According to the CHN radiographic atlas method,the difference in 1.0 to 3.9 years old,7.0 to 7.9 years old and 9.0 to 15.9 years old boy groups between skeletal age and the chronological age had statistical significance (P ＜0.05) ; the difference in 1.0 to 2.9 years old,8.0 to 11.9 years old,12.6 to 14.9 years old,and 17.0 to 18.0 years old girl groups between skeletal age and the chronological age had statistical significance (P ＜ 0.05).Besides,these skeletal age was higher than the chronological age.Conclusions Skeletal age assessed by the CHN radiographic atlas method in a majority of age groups was higher than chronological age.It should be cautious to estimate the contemporary Chinese children skeletal age of hand and wrist when using the CHN radiographic atlas method.

BACKGROUND:During the healing of fractures, removal of sciatic nerve can result in insufficient mechanical rigidity of newborn woven bone. However, there are less reports concerning the denervation effects during distraction osteogenesis. OBJECTIVE:To observe the effect of removal of the sciatic nerve on bone regeneration and the expression of Runt-related transcription factor 2 (Runx2) protein during distraction osteogenesis in a rabbit model. METHODS:Twenty-four adult male New Zealand rabbits were selected and underwent left tibial osteodistraction to construct animal models of distraction osteogenesis. Before distraction, the animals were randomly divided into group R (resecting the left sciatic nerve) and group I (intact left sciatic nerve). Six weeks after completion of distraction, the animals were kil ed and the lengthened tibias were harvested for radiography, three-dimensional CT reconstruction, histological evaluation, connectivity density (Conn.D) evaluation. RESULTS AND CONCLUSION:New regenerated bone was present and Runx2 protein was expressed in the distraction gaps of al animals at the end of the study, as revealed by radiography, three-dimensional CT reconstruction, and histological observation. However, less new bone formation and a lower degree of mineralization and expression of Runx2 protein were observed in group R compared with group I. The results suggest that the denervation appears to have an inhibitory effect on bone formation and the expression of Runx2 protein during distraction osteogenesis.

OBJECTIVETo compare the antitussive activity of three kinds of Stemonae Radix specified in the Chinese Pharmacopoeia, including roots of Stemona sessilifolia, S. japonica and S. tuberosa.

METHODThe antitussive activity was determined in mouse after cough induction by ammonia aerosol stimulation and the number of cough in 2 min were detected with codeine as positive control.

RESULTAll the decoctions, the total alkaloid fractions and non-alkaloid fractions of S. sessilifolia, S. japonica and three chemical types of S. tuberosa showed significant antitussive effect and exhibited a dose-dependent inhibition of coughing. The ED50 values showed that the antitussive activity strength for both total alkaloid fractions and the decoctions are: S. tuberosa (Type I) > S. sessilifolia > S. japonica. The total alkaloid fractions had more potent atitussive activity than the decoctions and non-alkaloid fractions. The antitussive activity strength for the three chemical types of S. tuberosa is: Type I > Type III > Type II. The samples from different producing areas for the same species of Stemonae Radix had no significant differences in antitussive activity. The result also showed that the honey-processed slice had much stronger antitussive activity than raw slice.

CONCLUSIONThe antitussive efficacies of Stemonae Radix were influenced by chemical diversity both in same species and among different species, different fractions and processed method.
