Objective To investigate the effect of exercise on calcium modulin in myocardial sarcoplasmic re-ticulum of animal type 1 diabetes model in rat. Methods A total of 40 Spragne-Dawley rats were randomly dividedinto 4 groups : a normal control group, an exercise training group, a diabetes group and a diabetes plus exercise-traininggroup. At the end of 4- week-exercise training after the establishment of the diabetes model by intraperitoncal injectionof sterptozotocin, the animals were sacrificed and the level of blood glucose, insulin, blood fat and glycosylated serumprotein were tested. The gene expression of calcium modulin proteins was measured by reverse transcription-polymerasechain reaction, and the Western blotting technique was used to measure the protein of sarcoplasmic endoplasmic reticu-lure Ca<'2+> -ATPase (SERCA2) and phaspholamban (PLB). Results The level of biochemical indicator of exercisegroup is not affected when comparing with that of the control group, but significantly changed in diabetic group ( P <0. 01 ) ; The level of blood glucose, insulin, blood fat and glycosylated serum protein were ameliorated in diabetic rats inthe exercise training group. No significant changes in mRNA level of SERCA2, PLB and ryanodine receptor type 2(RYR2) were observed between control and diabetic group, the same to protein expression of SERCA2 and PLB. Butexpression of calcium modulin mRNA was significantly increased in exercise group and diabetic rats in the exercisetraining group comparing with that of the control and diabetic groups ( P < 0.01 ), the same to protein expression ofSERCA2 and PLB. Conclusion Exercise exerted good protective effects on the myocardial injury with 1 type diabetesrat, which might attribute to the upregnlated expression of SERCA2, PLB and RYR2 in diabetic rat heart.

Objective To identify one umbilical blood sample with abnonnal gap-PCR products of three bands of α2,-α3.7 and-SEA.further family pedigree were analyzed for the source of genetic variations,Methods One fetal umbilical blood sample was drawn from a woman of 24-weeks pregnancy.Gap-PCR for α-thalassemia was routinely conducted and abnornlal three bands of α2.-α3.7 and-SEA were observed.which could not be interpreted according to the kit manual and suspected as rare variation.With informed consen,DNA samples from the parents and grandparents were obtained for further study.Singleplex andnested PCR techniques were utilized to analyze the molecular characteristics of DNA samples from this fetus and its parents and grand-parents.Results Hematological phenotype study showed that fetal Hb Ban's was 7.6%,and its mother and maternal grandfather were both with typical α-thalassemia.while its father,grandfather and grandmother and maternal grandmother are without abnormal hematological change.Molecular study showed that fetal blood DNA was a heterozygosity for HKaa and-SEA.its father and grandfather are both HKαα/αα,its mother and maternal grandfather are both-SEA/aa,its grandmother and maternal grandmother are with both normal alleles of αα/αα.Then after genetic counseling the fetas was saved and iS a she baby now.Conclusion ThroUgh careful molecular tests one case of prenatal heterozygosity of HKαα/-SEA was identified,and the fetus is kept successfully through careful clinical counseling.

Objective To analyze a rare genotype with β-thalassemia intermadia.Methods Phenotypic analysis was performed using routine hematological tests to measure red blood cell parameters and high performance liquid chromatography (HPLC)was used to measure hemoglobin fractions.The β-globin gene mutations were conducted using reverse-dot-blot and DNA sequencing of the breakpoint region were characterized with gap-PCR.Results The proband had a trait of thalassemia intermedia with reduced hemoglobin (86 g/L).The proband's father had a trait of microcytic hypochromic with reduced mean corpuscular volume(MCV),mean corpuscular hemoglobin (MCH) (63.7 fl and 20.4 pg,respectively) and an elevated level of HbA2.He had the phenotype of heterozygosity for β-thalassemia.The preband's mother,grandmother and sister had a trait of heterezygote for hereditary persistence of fetal hemoglobin (HPFH) with elevated level of HbF,which were 28.3%,21.1% and 33.7%,respectively.After molecular characterization of the family members,the proband was identified as a patient with β-thalassemia intermedia caused by co-existence of β-thalassemia(β41-42) and HPFH-6.The father was heterozygoas for β-thaiassemia (β41-42/βN) and the mother,grandmother and sister were all heterozygons for HPFH-6.Condusions A rare β-thalassemia intermedia case resulting from compound heterezygote of β41-42 with HPFH-6 is found.This study may provide clinical experiences for antenatal diagnosis.

Objective The rapid multiplex PCR (MPCR) system for detection of genes encoding aminoglycoside resistance in Staphylococcus aureus was developed. The distribution of antibiotic resistant genes acc(6')-Ie+aph(2″), aph(3')-Ⅲa and ant(4')-Ia in Guangzhou was analyzed using the established system.Methods S. aureus strains were identified and susceptibility tests were performed using VITEK-60 or PHOENIX-100 system as recommended by the manufacturer. Aminoglycoside resistance was determined by disk diffusion method. MPCR system for detection of antibiotic resistance genes was optimized.Results The MPCR assay was established successfully. The prevalence of acc(6')-Ie+aph(2″), aph(3')-Ⅲa and ant(4')-Ia in the 124 clinical S. aureus isolates was 62.1%, 32.3% and 1.6%, respectively as analyzed by MPCR. Good correlation between antibiotic resistance phenotypes and genotypes was observed. One or more of the genes encoding aminoglycoside modifying enzymes could be detected in all gentamicin- or netilmicin- or amikacin-resistant isolates. The acc(6')-Ie+aph(2″) gene was identified in 72 of 74 mecA-positive isolates.Conclusions This MPCR system could be used for rapid and reliable analysis of the antibiotic-resistant genotypes of clinical S. aureus isolates. The gene acc(6')-Ie+aph(2″) may be the predominant determinant of aminoglycoside resistance, followed by gene aph(3')-Ⅲa. The prevalence of ant(4')-Ia gene is relatively low.

Objective To evaluate the efifcacy and safety of hemostatics of injected gelatin matrix (HIGM) under the guidance of contrast-enhanced ultrasound (CEUS) for treating splenic trauma in canine model. Methods A total of 24 commercial hybrid dogs underwent celiotomy with creation of uniformly blunt splenic trauma lesion of 4.0 cm×4.0 cm×2.5 cm (length, width and depth, respectively) by hemostatic clamp. Subjects were prospectively randomized into two groups. The treatment group was treated with HIGM under the guidance of CEUS and the positive control group received thrombin solution. Conventional ultrasound and CEUS were performed to record the ascites and the splenic lesion areas at 1st, 3rd, 7th, 14th and 21st day. The ifne needle biopsy and splenectomy were performed for histopathologic examination. The weight, free intraperitoneal lfuid and injury site were compared with t test between HIGM and postive group. Results All animals in two groups survived. All dogs stopped hemorrhage after injection of HIGM under CEUS guidance. The area of injury site was (12.91±0.89) cm2, (4.45±0.75) cm2 and (1.38±0.23) cm2 at 1st, 3rd and 7th day and splenic lesions were not found at 14th and 21st day in all dogs (n=12) of HIGM group. The splenic lesion was (16.74±0.91) cm2, (11.26±0.99) cm2, (8.02±0.82) cm2 and (1.58±0.36) cm2 in the postive group at 1st, 3rd, 7th and 14th day and splenic lesions were not found at 21st day in all dogs (n=12). At 7th and 14th day post-injection, lesion areas were statistically significant between two groups (t=27.162, P=0.008;t=15.129, P=0.001). Free intraperitoneal lfuid was (0.91±0.05) cm at 1st day detected by conventional ultrasound and free intraperitoneal fluid was not found at 3rd, 7th, 14th and 21st day in all dogs (n=12) of HIGM group. The free intraperitoneal fluid in thepositive group was (1.96±0.17) cm, (1.30±0.11) cm and (0.81±0.12) cm at 1st, 3rd and 7th day and free intraperitoneal lfuid was not found at 14th and 21st day in all dogs (n=12). At 1st, 3rd and 7th day post-injection, free intraperatitoneal lfuid was statistically significant between two groups (t=20.934, P=0.003; t=41.310, P=0.000; t=22.520, P=0.000). Histopathological examination showed that there was no foreign body and foreign body granuloma and the structure of red pulp was recovered at 7th, 14th and 21st day. Gross anatomy showed that the splenic injury site was recovered completely without complications. Conclusion This study explored the value of HIGM for splenic trauma and provided a preliminary experimental evidence for clinical treatment.

In the basis of a large amount of literatures, this article sumed up the characteristics and application of eggshell membrane.

Objective: To observe the clinical efficacy of sinew-bone balancing manipulation in treating lumbar disc herniation (LDH) and offer clinical evidence to support the concept of paying equal attention to sinew and bone. Methods: Sixty LDH patients were randomized into an observation group and a control group, with 30 cases in each group. The observation group was treated with the sinew-bone balancing manipulation, and the control group received conventional Tuina (Chinese therapeutic massage) manipulation. The clinical efficacy and posterior muscle chain tone effect were compared between the two groups by observing the visual analog scale (VAS) score, Japanese Orthopaedic Association (JOA) score, and posture-associated indicators. Results: The total effective rate was 86.7％ in the observation group, higher than 76.7％ in the control group, but the between-group difference in efficacy was statistically insignificant (P>0.05). After treatment, the VAS and JOA scores, angle-dependent muscle tone indicator of the posterior muscle chain, and lumbar posture symmetry showed significant changes in both groups (P<0.05). The VAS and JOA scores, angle-dependent muscle tone indicator of the posterior muscle chain, and lumbar posture symmetry in the observation group were significantly different from those in the control group after treatment (P<0.05), but the between-group difference in the general posture symmetry was statistically insignificant (P>0.05). Conclusion: Both the sinew-bone balancing and conventional Tuina manipulations can reduce pain in LDH patients, improve lumbar function, and adjust the angle-dependent muscle tone coefficient of the posterior muscle chain and lumbar posture symmetry; except for the general posture symmetry of the posterior muscle chain, the sinew-bone balancing manipulation wins out over the conventional Tuina manipulation.

Objective: To observe the therapeutic efficacy of sinew-bone balancing manipulation plus exercise therapy in treating postures of primary school students with upper crossed syndrome (UCS).Methods: Sixty pupils with UCS were divided into an exercise group and a combination group using the random number table method, with 30 cases in each group. The combination group received treatments of sinew-bone balancing manipulation plus exercise therapy, while the exercise group received exercise therapy alone. The two groups received interventions once every other day, for a total of 1 month. The sagittal static posture assessment total score, forward head angle (FHA) and forward shoulder angle (FSA) were compared before and after treatment; the sagittal static assessment total score, FHA and FSA were compared between the exercise group and the combination group. Results: Before treatment, there were no significant differences comparing the sagittal static posture assessment total score, FHA and FSA between the two groups (all P>0.05); after treatment, the sagittal static posture assessment total score, FHA and FSA decreased in the two groups, with intra-group statistical significance (all P<0.01), and were lower in the combination group than in the exercise group, with inter-group statistical significance (all P<0.01). Conclusion: Sinew-bone balancing manipulation plus exercise therapy can notably improve the FHA and FSA and reduce the sagittal static posture total score in pupils with UCS, so as to correct the bad postures and adjust UCS physique. It can produce more significant efficacy compared with exercise therapy alone.

Objective To assess if the ratio of ApoB/ApoA1 is related to the metabolic syndrome and its components. Methods 709 adults living in Chongqing were enrolled. Weight, height, blood pressure, waist circumferences, fasting plasma glucose(FPG) , fasting serum insulin(FIns) and lipids were measured. ApoB/ApoA1 ratio, BMI and insulin resistance index were calculated. Results ApoB/ ApoA1 ratio was increased in subjects with insulin resistance(IR)and MS. Compared with the low ApoB/ ApoA1 ratio group, the high ApoB/ApoA1 ratio group was more likely to get MS(OR=3.5)and IR(OR =2.3) (P<0.001). Conclusions ApoB/ApoA1 ratio is strongly associated with IR, MS and its components, and a high ApoB/ApoA1 ratio is a valuable marker of MS.
