TCM believes that physical tendons and bone are interdependent, keeping dynamic balance, and they influence each other pathologically. Physical tendons and bone balance is human spine physiological state. Physical tendons and bone imbalance is the important pathogenesis of spine and related diseases. The core of physical tendons and bone balance-regulating theory is the physique homology and syndrome differentiation and treatment. This article expounded from the above aspects in details.

[Objective] Expressions of human epidermal growth factor receptor 2(HER-2),p53,estrogen receptor (ER),and progesterone receptor (PR) in tissues of breast invasive ductal carcinoma are not only applied to determine the therapeutic regimen,but they may also be related to the prognosis.We investigated the levels of these proteins among different clinical stages and the correlations.[Method] One hundred and thirty-eight tissues from cases with breast invasive ductal carcinoma were tested with immunohistochemistry.New scoring standards and rank test were applied.The indices were digitalized and semi-quantified.[Results] In the tissues from high clinical stage,the expression of HER2 was significantly increased,while expression of PR was markedly decreased.[Conclusion] Expression of HER2 and PR might be better markers for predicting clinical stages and prognosis.

This paper described the results of the optimal method for preparation and extraction of lectin from Phaeoporus obliquus(Pers ex Fr).(J.Schroet).We determined the optimal buffer solution using the ag-glutination test with 2% hare blood cells.The optimal extraction process included the following parameters that were conformed by optimization analysis: material-water ratio,extraction time,concentration of sodium chloride and the pH value.The results are that the agglutination indexes of POL using TBS and PBS extrac-tion buffer were 64 and 16,respectively.The optimal extraction process is that,the material-water ratio was 1:50,the extraction time was 20 h,while the concentration of sodium chloride was 0 mol/L and pH was 8.0.The agglutinability of POL was 256 examined by this method.The optimized extraction process is stable and practicable,which may supply some basis for the application of the lectin from Phaeoporus obliquus in immunoregulation.

Objective To measure the concentration of serum transthyretin (TTR) of patients with different stages of diabetic retinopathy (DR).Methods A total of 176 patients with diabetes mellitus were included in this study.There were 104 males and 72 females.The patients aged from 21 to 74 years,with the mean age of(56± 11) years.The diabetes duration raged from 1 to 30 years,with the mean diabetes duration of (10 ± 7) years.The HbA 1C was 5.2％-14.1％,with the mean HbA 1C of (8.6 ± 2.0)％.According to the fundus examination,58 patients had DR (33.0％),but the other 118 patients not (67.0％).For these DR patients,10 patients were in stage Ⅰ (5.7％),26 patients in stage Ⅱ (14.8％),8 patients in stage Ⅲ (4.5％),and 14 patients in stage Ⅳ (8.0％).The concentration of serum TTR was measured by enzyme-linked immunosorbentassay kit.The differences in the concentration of serum TTR between different DR stages were compared.Bivariate analysis was used to analyze the influencing factors of TTR.Results The concentrations of serum TTR of the patients without DR or with DR of stage Ⅰ to Ⅳ were (224.96±65.47),(383.68± 102.99),(247.44±63.21),(228.2 ± 45.89),(189.34± 70.12) mg/L,respectively.The difference between different DR stages was statistically significant (F=14.690,P＜ 0.001).Bivariate analysis showed that the concentration of TTR was correlation to DR (r=0.179,P=0.017).There was no correlation between the concentration of TTR and diabetes duration (r=-0.027,P=0.727),hypertension (r=0.018,P=0.810),hyperlipoidemia (r=0.101,P=0.182),and the use of insulin (r=-0.032,P=0.675).Conclusion The concentration of serum TTR was increased in early DR patients,and gradually decreased with the progression of DR.The concentration of TTR is correlated to DR.

OBJECTIVETo study the effects of VAC on starting the process of wound healing and decreasing apoptosis.

METHODSTo examine the variations in expression of proto-oncogenes c-myc, c-jun and Bcl-2 in pig wound model with acute full-thickness skin defect and human chronic wounds by immunohistochemistry, calculate the numbers of expressive positive cells and the labelling index (LI), and observe the process of wound healing.

RESULTS(1) In pig experiment, the wound in experimental group was very clean and without obvious exudates, many neoepiderm and granulation tissue rapidly appeared or formed after 6 days, and healed completely by the 25th day. On the contrary, in the wound of control group, more exudates and blood crust could be seen and fewer neoepiderm and granulation tissue appeared after 6 days and was healed by 30th day. Immediately after the wound was created, the expression of c-myc, c-jun and Bcl-2 was lower and mainly situated in nucleus or cytoplasma of the basilar cells. After the wound was created in control group, or after starting the VAC treatment in experimental group, their expression rapidly and obviously increased, the distribution of the positive cells also became enlarged, but the amount of expression decreased rapidly after the expressive peak have reached. In the successive 12 days following the wound was created, the expression of c-myc, c-jun and Bcl-2 in the experimental group was constantly higher than that of the control group. (2) In human chronic wounds, there wasn't obvious secretions and more healthy granulation tissue was rapidly formed after VAC treatment. The expression of c-jun was mainly located in cytoplasma of basilar cells of epithelium, dermal fibroblasts and inflammatory cells, and the positive cell and labelling index obviously decreased. The expression of c-myc and Bcl-2 was mainly in cytoplasma of basilar cells, but the amount of expression and the labelling index became obviously increased after VAC treatment.

CONCLUSIONSVAC could rapidly start the healing course of the pig' s acute skin wound and human chronic wound, decrease apoptosis of the reparative cells, so as to accelerate wound healing.

Objective To evaluate the development of the sphincter muscle complex(SMC)and defecation function in pediatric patients with congenital anorectal malformations(ARM).Methods A total of 64 children underwent MRI,among whom 39 were patients with ARM,and the others were patients without ARM undergoing MRI because of other dieases.The dimensions of the SMC in different planes were evaluated with different sequences and coils.The relationship between the SMC development and the defecation function was investigated.Results In control group,the absolute value of SMC width was (3.63?0.22)mm,which had a high correlation with age(r=0.998,P0.05).The SMCs in intermediate ARM patients[muscle index(MI)=0.47?0.05]and low ARM patients(MI=0.49? 0.05)were well developed.The SMCs in a portion of patients with high ARM(MI=0.28?0.06)were poorly developed,when MI≤0.18,anorectal contraction pressurewas significantly lower(t=3.55, P0.18[(0.85?0.20)vs(2.24?1.02)kPa].The length of anal canal with high-pressure[(10.88?3.64)vs(20.26?4.34)mm]was shorter(t=5.18,P0.18,the anorectal angle was less than 90 degrees,and normal continent function was found in 21 of 23 cases(91%).Conclusion MRI can be employed to evaluate the development of SMC in patients with ARM,MI was an objective criteria to evaluate the development of SMC.When MI≤0.18, maldevelopment of SMC will be highly suspected.

Objective To evaluated the clinical efficacy and safety of valsartan or benazepril combined with atorvastatin in the treatment of chronic cardiac failure in elderly patients.Methods Eighty-six cases with chronic cardiac failure were recruited in this study and randomly divided into treatment group ( n =42 ) and control group ( n =44 ).Patients in treatment group were received valsartan 80 mg · d-1 orally plus atorvastatin 10 mg · d-1 orally, patients in control group received benazepril 10 mg · d-1 orally plus atorvastatin 10 mg · d-1 orally.The course was 3 months.After treatment , the clinical efficacy , serum level of brain natriuretic peptide and adverse event were compared between the two groups.Results The total clinical efficacy of treatment group and control group were 90.48% and 86.36% respectively with no statistical difference ( P>0.05 ).The serum level of brain natriuretic peptide sig-nificant decreased in the both groups ( P<0.05 ) after treatment.And the serum level of brain natriuretic peptide in treatment group was significant lower compared with that in control group after treatment ( P<0.05 ).There were no statistical difference on adverse drug reactions between two groups ( P>0.05 ).Conclusion The clinical efficacy and safety were not significantly different for valsartan or benazepril combined with atorvastatin in the treatment of chronic cardiac failure in elderly patients .

This study was aimed to investigate the prevalence and genotype distribution of heterozygotes in beta-thalassemia combining deletional alpha-thalassemia by using molecular detection and haematological methods. Three common deletions of alpha-thalassemia were detected by using gap-PCR. The mutations of beta-thalassemia were identified by using PCR with reverse dot blot hybridization. The routine analysis of blood cells was carried out. The results indicated that 15 cases from the 81 beta-thalassemia traits were found to be the compound heterozygosity for beta-thalassemia and alpha-thalassemia with 9 different types of gene defects with 18.52% detection rate. There were 6 cases (7.41%) of beta-thalassemia heterozygote combining alpha-thalassemia-1 gene (--(SEA)/alphaalpha), 8 cases (9.88%) combining with alpha-thalassemia-2 gene including 6 (7.41%) right ward deletion (-alpha(3.7)/alphaalpha) and 2 (2.47%) left ward deletion (-alpha(4.2)/alphaalpha), and 1 case (1.23%) combining deletional HbH gene (--(SEA)/-alpha(3.7)). No significant differences were found between beta-thalassemia heterozygotes combining deletional alpha-thalassemia and pure beta-thalassemia in all RBC parameters. It is concluded that the incidence of beta-thalassemia heterozygotes combining with deletional alpha-thalassemia is frequent in Wuzhou city. The hematological analysis can not give specificity for diagnosing these dual heterozygotes. Gap-PCR as a routine method for thalassemia screening has the advantages in reducing the possibility of failing to detect the combining heterozygosity for beta-thalassemia and alpha-thalassemia. It is more useful for genetic counselling and prenatal diagnosis of this disease.

OBJECTIVETo explore the relationship between the mutations of epidermal growth factor receptor (EGFR) gene and clinicopathological characteristics in patients with non-small cell lung cancers (NSCLC).

METHODSParaffin-embedded tissue specimens were obtained from 1444 patients with NSCLC. The genomic DNA was extracted. Mutations of EGFR gene (exons 19 and 21) were detected by real-time PCR.

RESULTSDNA was available in 1410 cases. Somatic mutations of the EGFR gene were identified in 401 cases (27.8%). Among patients with EGFR mutations, 41.4% (n=166) had del E746-A750 of exon19, 6.7% (n=27) had del L747-P753insS of exon 19, 50.3% (n=201) had L858R of exon 21, and 1.5% (n=6) had L861Q of exon 21. Woman, non-smoker and adenocarcinoma showed a higher percentage of EGFR mutation (43.2%, 37.6%, and 33.5%, respectively). However, there was no association among age, grades, lymph node metastasis, and TNM stages (P>0.05). The mutation rate of BAC subtype (61.3%, 19/31) and adenocarcinoma with BAC features (48.0%, 12/25) was significantly higher than that of conventional adenocarcinoma (32.4%, 336/1038). A further assess of the smoking status found a trend that the more increased smoking exposure, the lower the incidence of EGFR mutations. A multivariable analysis revealed that adenocarcinoma, never smoking, and female were independently associated with EGFR mutations (odds rations=3.381, 2.393, and 1.727, respectively).

CONCLUSIONSThe detection rate of EGFR mutation is higher in Chinese patients, especially in non-smoking female patients with adenocarcinoma. Real-time PCR is a sensitive and accurate method to detect the mutations of EGFR gene and can therefore provide useful information for clinical treatment.
