Objective To investigate the correlation of diabetic skeletal muscle disease with macroangiopathy, and to explore the related genes of Shenqi Compound Recipe (SCR) in preventing and treating diabetic skeletal muscle disease by using gene chip technique, thus to reveal the molecular mechanism. Methods KKAy mice were fed with water containing nitri oxide synthase inhibitor of Nω-nitro-L-arginine methyl ester ( L-NAME) and high fat diet to induce the macroangiopathy complicated with type 2 diabetes. The experimental animals were divided into normal c57BL/GJ group, KKAy group, model group, SCR group (in the dosage of 14.4 g·kg-1·d-1) and rosiglitazone group ( in the dosage of 1.33 mg·kg-1·d-1) , 15 in each group. The medication groups were administered the corresponding agents for 8 consecutive weeks just as the modeling began. During the experiment period, blood glucose was monitored. At the end of the experiment, the abdominal aorta and skeletal muscle of mice were taken out for the observation of morphological changes, and differentially expressed genes of skeletal muscle between SCR group and model group, and between model group and KKAy group were detected by gene chip technique. Results SCR had an effect on relieving the atrophy, edema, fracture, and inflammatory changes in the skeletal muscle. There were 198 genes differentially expressed between model group and KKAy group, including 119 up-regulated genes and 79 down-regulated genes. There were 70 genes differentially expressed between SCR group and model group, including 33 up-regulated genes and 37 down-regulated genes. In the two comparison groups, 7 genes ( Celsr2, Rilpl1, Dlx6as, 2010004M13Rik, Anapc13, Gm6097, Ddx39b) showed reversed differential expression. Conclusion Diabetic skeletal muscle disease is associated with macroangiopathy. SCR has preventive effect on diabetic skeletal muscle lesion, and the mechanism may be related to the regulation of Celsr2, Rilpl1, Dlx6as, 2010004M13Rik, Anapc13, Gm6097, Ddx39b gene expression.

OBJECTIVETo identify the correlation of the volume of residual urine (VRU) with the severity of bladder outlet obstruction (BOO) and detrusor contractility in patients with benign prostatic hyperplasia (BPH).

METHODSA total of 152 patients with clinically diagnosed BPH underwent ultrasonography for measurement of the prostate volume and RVU, free uroflowmetry, and urodynamic examination for the severity of BOO and detrusor contractility. Using the software SPSS20. 0, we analyzed the correlation between the ultrasonographic results and urodynamic parameters and compared the two sample means by the t-test.

RESULTSThe prostate volume was correlated positively with BOO severity (r = 0.432, P < 0.01) and detrusor contractility (r = 0.343 , P < 0.01) while Qmax negatively with BOO severity (r = 0.327, P < 0.01) but not significantly with detrusor contractility (r = 0.123, P > 0.05). VRU showed a significantly negative correlation with detrusor contractility when > 150 ml (r = -0.490, P < 0.01), even more significantly when > 300 ml (r = -0.717, P < 0.01), but exhibited no significant correlation with it when ≤ 150 ml (r = 0.041, P > 0.05).

CONCLUSIONVRU can somehow predict the detrusor function. For patients with VRU > 150 ml, especially for those with VRU > 300 ml, the detrusor function should be evaluated and urodynamic examination is recommended for exact assessment of BOO severity and detrusor contractility.

Objective To explore the relationship between the prothrombotic state and blood coagulation-fibrinolysis system changes with deep venous thrombosis(DVT)in aged patients after total joint arthroplasty,and to propose preventive measures.Methods 400 patients who underwent total hip or knee replacement from January 2003 to June 2011 were classified into suspected DVT(n=200 cases)and non-suspected DVT(n=200 cases)according to Well's clinical scoring system.The patients were divided into 4 subgroups based on the measures to prevent DVT:low molecular weigh heparin group,intermittent pneumatic bag compression group,combined above measures group,control group who refused any preventive measures.Plasma thrombin-antithrombin complex(TAT),plasmin-α2 antiplasmin complex(PAP)were determined preoperatively.Venous Doppler ultrasound was performed before surgery,4 d and 10 d after surgery to detect the presence of DVT.Results Totally 71 cases(17.8％)were diagnosed as DVT and 5 cases(1.3％)as pulmonary thromboembolism(PTE).The incidence of DVT in suspected DVT group(28.5％,57 cases)was lower than in non-suspected DVT group(7.0 ％,14 cases)(x2 =31.66,P＜ 0.01).Among patients with suspected DVT,the DVT prevalence in combined measures group(2.0 ％,1 cases)was decreased than in low molecular weigh heparin group(14.0％,7 cases),intermittent pneumatic bag compression (34.0％,17 cases)and control groups(64.0％,32 cases)(x2=4.89,17.34,18.01,all P＜0.05).In the patients with non-suspected DVT,the DVT prevalence in combined measures group(0.0％)was lower than in control group(24.0 ％,12 cases)(x2 =13.64,P＜0.01).The average preoperative level of TAT[(9.63±3.06)μg/L]in patients with DVT was higher than without DVT[(2.59±0.87)μg/L](t=35.70,P＜0.01),while PAP level in patients with DVT[(38.52± 21.13)μg/L]was reduced than without DVT[69.75±30.26)μg/L](t=8.27,P＜0.01).Conclusions The levels of TAT and PAP before total hip or knee replacement are predictive for lower extremity DVT.The clinical effectiveness of Well's scoring on DVT prevention is dependent on the different TAT and PAP state.

OBJECTIVE:To investigate the effects of UGT1A6 and UGT1A9 gene polymorphisms on blood concentration of valproic acid in Han epileptic patients.METHODS:Totally 107 Chinese Han epileptic patients were selected from outpatient department of our hospital during Jan.2014-Apr.2015.They were given valproic acid monotherapy treatment for 3 months to 6 years.The steady state concentration ofvalproic acid was detected by EMIT.UGT1A6 (rs2070959,rs6759892) and UGT1A9 (rs13418420,rs2741045,rs2741049,rs6731242,rs72551330) genotypes were detected by MALDI-TOF-MS.The correlation of gene polymorphism with con centration dose ratios (CDR) of valproic acid was investigated.RESULTS:UGT1A9 rs72551330 mutation had not been detected,and the frequency of genotypes in other 6 sites were all in line with Hardy-Weinberg balance (P＞0.05).The CDR of valproic acid in pa tients with UGT1A6 rs2070959,rs6759892 mutation (AG+GG or TG+GG type) were significantly lower than those with wild homozy gote (AA or TT type),with statistical significance (P＜ 0.05).There was no statistical significance in CDR of valproic acid among patients with UGT1A9 rs13418420,rs2741045,rs2741049 and rs6731242 wild homozygote and mutation (P＞0.05).CONCLUSIONS:UGT1A6 rs2070959,rs6759892 gene polymorphisms of Han epileptic patients are associated with blood concentration of valproic acid,and the patients with UGT1A6 rs2070959,rs6759892 mutation need more dose ofvalproic acid.

Background Congenital fibrosis of extraocular muscles (CFEOM) affects patient' s appearance and quality of life,and no effective treatment for this disease is available.Imaging study is helpful for exploring the pathogenesis of CFEOM.Objective This study was to describe the characteristics of CFEOM associated with limb movement disorder using magnetic resonance imaging (MRI).Methods A family with CFEOM associated with limb movement disorder was investigated in Renmin Hospital of Wuhan University.Disease history was collected and the pedigree was investigated.Ophthalmologic examinations,including corrected visual acuity,refractive error,slitlamp examination,ophthalmoscopic examination,force of levator palpebrae superioris,ocular movement,eye position,forced duction test,and bell phenomenon examination,were performed.Ocular orbital and cranial MRI was performed in 4 CFEOM patients and 10 normal subjects to compare the structures of the extraocular muscles,motor nerve and cranium.Oral informed consent was obtained from each patient prior to any medical examination.Results A total of 1 1 members from 3 generations were investigated in this study,presenting with 4 cases of disease.The mode of inheritance of this family complied with the Mendelian autosomal dominant inheritance law.Clinical signs included disturbance of eye movement,deviation of eye position,ptosis,lack of Bell sign and positive reaction of passive pull test.In addition,unstable gait,improper body limb alignment,dysphasia and mental retardation were ohserved in 1 patient,which coincided with the diagnostic criteria of type 3 CFEOM.MRI results demonstrated that the levator palpebrae superioris,superior rectus and superior oblique muscle were clearly thinner,and the medial rectus,lateral rectus,inferior rectus muscle were thinning in the patients,showing significant differences in comparison with the normal controls(P＜O.05).The oculomotor and abducens nerves became thinner and even absent in the patients.Cranial MRI showed that Ⅲ-3 in the pedigree with callosum was shorter than that of the normal controls,suggesting that patient suffered from corpus callosum hypoplasia.Meanwhile,cranial MRI indicated the presence of cerebellar hypoplasia and the expansion of the fourth ventricle.Conclusions MRI demonstrates consistent abnormalities of the oculomotor nerves and abducens nerves in the affected individuals in this CFEOM 3 family,and some affected members exhibit two types of central nervous system abnormalities-corpus callosum and cerebellar hypoplasia.These findings suggest that CFEOM 3 is primarily a neuronal disease.

Objective To evaluate the diabetes self-management program based on Chinese local patients in Nanjing community. Methods From April 2014 to June 2014, diabetes patients were recruited through health records system screening in the community health service centers, letter invitation, poster announcements at communities, and telephone notification. A total of 53 self-management groups were established. Nanjing diabetes self-management program included six 1-1.5 hours sessions scheduled on consecutive weeks, based on the blueprint of Shanghai Chronic Disease Self-Management Program (CDSMP) developed at Stanford University. Baseline and three-month later interviews were conducted respectively. Results A total of 636 patients were recruited and agreed to enter CDSMP; 603 completed the 6-session activities, with the response rate being 94.8%. Compared to baseline, nine of the patients' the awareness rate of diabetes-related knowledge, six of self-management behaviors, the scores of quality of life in physical component summary [(47.51 ± 9.47) vs. (49.10 ± 8.27) points, t=6.170, P=0.000] and mental component summary [(47.09±11.95) vs. (49.13±10.74) points, t=5.157, P=0.000] were all higher after three months (all P values<0.05). Three months after implementation, the level of systolic blood pressure, diastolic blood pressure, fasting plasma glucose and total cholesterol decreased respectively by (1.42±0.52) mmHg (1 mmHg=0.133 kPa), (0.98 ± 0.34) mmHg, (0.66 ± 0.16) mmol/L, (0.15 ± 0.56) mmol/L,the differences were statistically significant (tpaired values were 3.935, 2.030, 4.889, 4.899, all P values<0.05). Conclusion The diabetes self-management program based on Chinese local patients for Nanjing may improve patients' awareness rate of diabetes-related knowledge, self-management behavior, the quality of life, and health status. CDSMP could be applied effectively in Nanjing.

Objective To verify the reference interval for D-dimer assay and analyze the influence of age and gender on the ref-erence interval.Methods Inclusion criteria for reference individuals were established.60 healthy males and 63 females were enrolled and divided to three groups by age,including 20 to 39 years old group (20 males and 20 females),40 to 59 years old group (20 males and 23 females)and above 60 years old group (20 males and 20 females).Blood samples were drawn in cit-rate sodium anticoagulated tubes and D-dimer concentration was determined by three different coagulation analyzers using o-riginal reagents.According to CLSI guideline C-28-A3,the reference interval for each measurement system from reagent manufacturer was verified and the difference of D-dimer concentration between different age-group and sex-group was ana-lyzed using non-parameters tests.Results All reference intervals were verified for people under age 40,while one reference interval cannot be verified for people from 40 to 59 years old as same as one for people above 60 years old.D-dimer concen-tration increased with age and there was significantly different between 20~39 years old group and 40~59 years old group or above 60 years old group(P<0.05).There was only a significant difference between sex-group for people under age 60(P<0.05).Conclusion D-dimer concentration was associated with age and sex.For people under age 40,the reference inter-val from reagent manufacture can be verified and directly used in laboratory,while for people above age 60,the reference in-terval from reagent manufacture cannot be verified.The cause should be investigated and a new reference interval should be established separately when necessary.

BACKGROUND:Studies have found that combination of two of chitosan (CS), nano-hydroxyapatite (nHA) and poly(lactide-co-glycolide) (PLGA) can improve the mechanical properties and biocompatibility of the composite stent in certain extent as wel as improve osteogenic differentiation of the cels, but there is a certain distance from the ideal bone tissue engineering scaffolds.
OBJECTIVE:To study biocompatibility and osteoinductive activity of nHA/CS/PLGA scaffolds with different proportions in vitro.
METHODS: nHA/CS/PLGA scaffolds were prepared at mass ratio of 10:10:80, 10:20:70, 20:10:70 respectively by particle leaching method. And human bone marrow stem cels (hBMSCs) were co-cultured with these scaffolds in vitro. Adhesion, proliferation, and osteoinductive activity of these scaffolds were examined qualitatively and quantitatively by growth curve of hBMSCs on scaffolds. Gene expression of alkaline phosphatase activity and osteocalcin was detected by RT-PCR.
RESULTS AND CONCLUSION: hBMSCs could be attached, proliferated, and osteoinduced better on the nHA/CS/PLGA scaffold with the mass ratio of 20:10:70, compared to the other two groups of scaffolds. The differences were significant statisticaly (P< 0.05). Alkaline phosphatase and osteocalcin expressions were respectively higher in the scaffold with the mass ratio of 20:10:70 after 9-27 days of co-culture and 15-27 days of co-culture, in comparison with the other two groups of scaffolds. These findings indicate that the nHA/CS/PLGA scaffolds with the mass ratio of 20:10:70 demonstrated preferable biocompatibility and osteogenic inductivity, which is expected to be a promising scaffold material for bone tissue engineering.
