β-Amyrin synthase (β-AS) genes of Glycyrrhiza uralensis from 6 different regions were analyzed by PCR-SSCP and sequenced, then the correlationship between β-AS SNP and regions of Glycyrrhiza uralensis were determined. According to the 1 coding single nucleotide polymorphism on the first exon of β-AS gene at 94 bp site, Glycyrrhiza uralensis could be divided into 3 genotypes. In these genotypes, the percentage of 94A type in genuine regions was much higher, and it had significant differences with the percentage in non-genuine regions (P < 0.001). The results of the experiment proved that different β-AS genotypes at 94 bp site from different regions may be one of the important reasons to result in the genuineness of Glycyrrhiza uralensis.

OBJECTIVETo compare clinical outcomes between two suturing methods using non absorbable materials through drilling the bone and suturing anchors for the treatment of complete rupture of the deltoid ligament.

METHODSFrom January 2009 to January 2013, 58 hospitalized patients with ankle fracture combined with complete rupture of the deltoid ligament were treated with suturing using non absorbable materials through drilling the bone or suturing anchors. There were 29 patients who received suturing treatments using non absorbable materials through drilling the bone (Group A), including 18 males and 11 females, with an average age of (39.76 +/- 11.81) years old. According to the Lauge-Hansen classification, 12 patients had supination external rotation (SER) injuries with IV degree, 5 patients had pronation external rotation (PER) injuries with III degree, 10 patients had PER injuries with IV degrss, and 2 patients had pronation abduction injuries with III degree. There were 29 patients who received treatments with suturing using anchors (Group B), including 14 males and 15 females, with an average age of (41.79 +/- 13.28) years old. According to the Lauge-Hansen classification,9 patients had SER injuries with IV degree, 6 patients had PER injuries with III degree,13 patients had PER injuries with IV degree, and 1 patient had pronation abduction injuries with III degree. All the patients were treated with open reduction and internal fixation, as well as reconstruction of deltoid ligaments to restore the stability of the medial ankle structures. The clinical examination, imaging evaluation, American society for ankle surgery (AOFAS) ankle-hindfoot score and visual analogue scale (VAS) were used to evaluate the clinical results after operation, and the results of the two groups were compared and analyzed statistically.

RESULTSThe follow-up duration of the 58 patients ranged from 23 to 40 months,with an average of 27.3 months. All the patients had fracture union, and the mean healing time was 12.3 weeks (ranged, 10 to 17 weeks). There were no incision complications and ankle instability. There were no significant differences between two groups in AOFAS (P=0.666) and the VAS (P=0.905).

CONCLUSIONTreatments of complete rupture of the deltiod ligaments with the two suturing methods get similar good clinical effects, but the suturing using non absorbable materials through drilling the bone has several advantages such as reducing the financial burden of patients, saving social medical resources and avoiding the shortcoming in difficult removal of anchor suture.

OBJECTIVETo observe the effect of CKJ Recipe (consisting of Cordyceps sinensis polysaccharide, amygdaloside, and gypenosides) containing serum on the activation of rat primary hepatic stellate cells (rHSCs) and to explore its pharmacological mechanism.

METHODSrHSCs were isolated form liver and cultured for four days. Then they were divided into the normal control group, the model group, and the CKJ group. rHSCs in the model group and the CKJ group were treated with 2.5 ng/mL transforming growth factor beta1 (TGF-beta1) in serum-free DMEM for 24 h. Serum free DMEM (containing no TGF-beta1) was taken as the control for the normal control group. rHSCs in the CKJ group were treated with 5% CKJ-containing serum for 24 h. rHSCs in the other two groups were treated with 5% blank serum for 24 h.The protein expression level of a smooth muscle actin (alpha-SMA) was determined using high throughput screening (HCS) and Western blot. mRNA expression levels of alpha-SMA, collagen I (Col-I), platelet-derived growth factor receptor beta (PDGF-betaR), TGF-beta1, transforming growth factor beta receptor 1 (TGF-betaR1), and transforming growth factor beta receptor 2 (TGF-beta R2) were detected using quantitative RT-PCR.

RESULTSCompared with the normal control group, the protein expression level of alpha-SMA, mRNA expression levels of alpha-SMA, Col-I, PDGF-betaR, TGF-beta1, TGF-betaR1, and TGF-betaR2 significantly increased in the model group (P<0.05, P<0.01). Compared with the model group, the protein expression level of alpha-SMA, mRNA expression levels of alpha-SMA, Col-I, PDGF-betaR, TGF-beta1, TGF-beta1, and TGF-beta R2 significantly decreased in the CKJ group (P<0.05, P<0.01).

CONCLUSIONCKJ containing serum could inhibit the protein expression level of o-SMA, which was probably related with inhibiting TGF-beta1 and its related receptors.

OBJECTIVETo examine the recent incidences and trends of childhood malignant solid tumors in Shanghai.

METHODData from the population-based Shanghai Cancer Registry and related retrospective survey were used to analyze the patterns of incidence and trends of malignant solid tumors diagnosed between 2002 and 2010 in children aged 0-14 years. The distributions of incidences were described according to gender, age and cancer types which were classified according to International Classification of Childhood Cancer (ICCC). Annual age-standardized rates (ASRs) were adjusted by the world standard population. Approximate confidence intervals for standardized rate ratios (SRR) based Poisson distribution test-based methods were used to assess changes in incidence over the period 2002 - 2006 and 2007 - 2010.

RESULT(1)A total of 868 cases of childhood malignant solid tumors were diagnosed in Shanghai during 2002 - 2010, accounting for 65.8% of all childhood cancers. The ASR of 2002 - 2010 was 80.2 per million for all solid tumors. (2) The ASR was higher in boys (86.3 per million) than in girls (73.8 per million) with SRR 1.2 (95%CI 1.0 - 1.3). Incidence rate was the highest in the first five years of life with 93.4 per million. The age-specific incidence rates in 5 - 9 and 10 - 14 age groups were 65.2 and 79.3 per million, respectively. (3) CNS tumors, lymphomas, germ cell tumors, neuroblastoma, and soft tissue sarcomas were the top 5 most common solid tumors in children, with the incidence rate of 23.8, 11.0, 7.8, 7.7 and 6.8 per million, respectively. The patterns of subgroups varied in different age groups. Blastomas, such as neuroblastoma, retinoblastoma, were more common in the children aged 0 - 4 years, whereas epithelial carcinomas and bone tumors developed more frequently in elder children aged 10 - 14 years. (4) Compared with the ASR in 2002 - 2006, the ASR for both genders in 2007 - 2010 had no substantial changes (78.7 per million in 2002 - 2006 and 82.9 per million in 2007 - 2010). However, among boys, the incidence rate in 2007 - 2010 was significantly higher than that in 2002 - 2006 with SRR 1.2 (95%CI: 1.0 - 1.4). For specific subgroups of cancer, there were no substantial changes. Some cautions should be taken when interpreting results involving a small number of cases per year and those with wide 95% confidence intervals.

CONCLUSIONThe incidence rate of pediatric malignant solid tumors among males was higher than females during 2002 - 2010, and it differed among different age groups with the highest in the first five years of life. CNS tumor was the most common type of solid tumors in children. This was a unique characteristics comparing with adult reflected in disease spectrum and age of onset. The patterns of incidence and its trends for childhood malignant solid tumors in Shanghai could provide a basis for etiologic research and preventive interventions. The findings also suggest an urgent need for longer population-based surveillance to verify the pattern and changing trends.

OBJECTIVETo investigate the effect of preoperative use of viable Bifidobacterium supplement on the intestinal flora, immune status, inflammatory response and prognosis of patients undergoing colorectal cancer resection.

METHODSSixty patients with colorectal cancer were randomized into treatment group (n=30) and control group (n=30). Patients in the treatment group received oral viable Bifidobacterium with routine enteral nutrition and patients in the control group received routine enteral nutrition alone. The intestinal flora of stool was analyzed and stool SIgA, serum IgG, IgM, IgA, IL-6, and C-reactive protein (CRP) were detected.

RESULTSPostoperative Bifidobacterium/E.coli (B/E) ratio in the treatment group decreased significantly as compared to the preoperative ratio (2.01+/-0.36 vs 26.53+/-4.22, P<0.05). However, the ratios remained above one. Both preoperative and postoperative B/E ratios in the control group (0.72+/-0.14, 0.02+/-0.06) were significantly lower than those in the treatment group (P<0.05). Indexes of immunity and inflammation were not significantly different between the two groups (P>0.05). At day 9 after operation, stool SIgA was higher in the treatment group, while serum IgG, IgM, IgA, IL-6, CRP in the treatment group were lower (P<0.05). Postoperative septic complications in the treatment group was less than that in the control group (P<0.05), but other complications and hospital stay were comparable.

CONCLUSIONSIn patients with colorectal cancer, supplementation of viable Bifidobacterium before surgery can improve bacterial dysbiosis and immunity, and can reconstruct the balance of intestinal flora, and reduce infection complication of surgery.

OBJECTIVETo explore the mechanisms of puncturing Shenshu point in improving osteoporosis.

METHODSSerum levels of testosterone (T) and osteocalcin (BGP) in senescence accelerated mouse prone 6 (SAMP6, test animals) and senescence accelerated mouse resistant 1 (SAMR1, for control) were determined by radioimmunoassay and their femoral biomechanical properties were determined with three-point bending test before and after puncturing to observe the effect of puncturing on the femoral biomechanical properties and bone mineral contents.

RESULTSCompared with the SAMR1 control group, the serum level of T (20.91 +/- 3.41 nmol/L) decreased (11.09 +/- 1.48 nmol/L in SAMP6 mouse), BGP (6.7 +/- 2.07 microg/L) increased (12.29 +/- 2.29 microg/L in SAMP6 mouse), femoral bending strength lowered and fragility increased. These changes were all improved to some extent or normalized, serum T level 15.05 +/- 2.63 nmol/L and BGP 8.88 +/- 1.85 microg/L after needling at Shenshu point showed significant difference when compared with those in SAMP6.

CONCLUSIONPuncturing Shenshu point could effectively prevent the bone loss in SAMP6 mice, increase their bone strength, the therapeutic effect is partly by way of promoting the secretion of sex hormone, improving bone metabolism, suppressing bone transformation rate and increasing bone minerals.

OBJECTIVETo evaluate the relationship between periodontitis and the traditional risk factors of coronary heart disease (CHD), as well as the role in the mechanisms responsible for high-sensitivity C-reactive protein (hsCRP) in the relationship of peridontitis and CHD.

METHODSA periodontal examination was conducted on a total of 356 subjects, and community periodontal index of treatment needs (CPITN) was obtained from each subject. Periodontal status was categorized into TN < or =2, TN=3, TN=4 three groups according to the CPITN indexes. Fasting venous blood samples were collected from all the three group subjects, the serum hsCRP concentration and serological changes used in diagnosing CHD routinely were determined, and software of SPSS 16.0 were used to analyzed the relationship of periodontal, hsCRP concentration and routinely CHD serological indexes.

RESULTSIn the groups of TN < or =2, TN=3 and TN=4, the hsCRP level was (1.10 +/- 1.16), (1.86 +/- 2.34), (2.25 +/- 2.75) mg x L(-1), respectively. Compared with Group TN < or =2, the concentration of hsCRP in Group TN=3 and TN=4 were higher (OR = 1.24, OR = 1.31, respectively). Compared with group hsCRP < 3.0 mg x L(-1), more calculus and deep periodontal pockets were found in the Group hsCRP > or = 3.0 mg x L(-1) (P < 0.05).

CONCLUSIONThe serum hsCRP level is correlated with the severity of periodontal disease.
