Objective: To explore weather microRNA let-7c (miR-let-7c) could regulate myotrophin gene expression in rat’s H9c2 cardiac myocytes with possible mechanisms.
Methods: Recombinant plasmid carrying 3′ untranslated region (3′-UTR) of myotrophin and miRNA precursor of let-7c was co-transfected into Hela cells to construct the luciferase reporter system in order to measure luciferase activity. Rat’s H9c2 cardiac myocytes were cultured. The let-7c gene expression was detected by Taqman probe-based real-time PCR after let-7c miRNA precursor or let-7c miRNA inhibitor transfection respectively; protein expressions of myotrophin and nuclear factor-κB (NF-κB) were examined by Western blot analysis.
Results: Luciferase activity examination indicated that compared with recombinant luciferase gene expression carrier (pMIR-MTPN)+miR precursor negative control group, pMIR-MTPN+miR-let-7c miRNA precursor group showed reduced luciferase activity (59.30±9.90) % vs (98.10±15.10) %. Western blot analysis presented that compared with miR negative control group, miR-let-7c precursor group had decreased protein expressions of myotrophin (0.28±0.05) vs (0.90±0.09) and NF-κB (0.25±0.06) vs (0.75±0.07); in contrast, compared with Negative inhibitor group, miR-let-7c inhibitor group had increased protein expressions of myotrophin (1.14±0.09) vs (0.44±0.09) and NF-κB (1.09±0.05) vs (0.71±0.06), allP<0.05.
Conclusion: miR-let-7c could inhibit myotrophin expression via acting on its 3′-UTR domain and may also inlfuence NF-κB signaling pathway in rat’s H9c2 cardiac myocytes.

OBJECTIVETo explore clinical effect of vacuum sealing drainage (VSD) combined with discontinuous windowing technique for repairing large area exposed wounds of Achilles tendon.

METHODSFrom July 2009 to May 2014, 11 patients with large exposed wounds of Achilles tendon were treated, including 5 males and 6 females with an average age of 43 years old (aged from 7 to 65 years old). Among them, 4 cases were skin necrosis caused by heavy objects abrasion and contusion; 3 cases were caused by distal tibiofibula fractures; 3 cases were caused by bicycle-spoke injuries; 1 case was caused by diabetes. Areas of exposed Achilles tendon were from 6 cmx3 cm to 14 cmx5 cm without tendon rupture or bone exposed. After debridement, discontinuous fenestration on Achilles tendon was made by knife blade parallel with longitudinal axis of Achilles tendon, combined with Vacuum Sealing Drainage (VSD) treatment.

RESULTSAfter drainage treatment with one VSD cycle (5 to 7 days), abundant fresh granulation tissues were growing on all wounds and survived well after the second phase dermatoplasty. All patients were followed up for 12 to 24 months, the color of skin flap was good, the texture was soft without burst. At 3 to 4 months after operation, subcutaneous fat was appeared under the flap, the skin was sliding, movement of ankle joints was good. No delayed Achilles tendon rupture were occurred.

CONCLUSIONVacuum sealing drainage (VSD) combined with discontinuous fenestration is a simple, safe and effective method for repairing large area exposed wounds of Achilles tendon,which could minimize the secondary damage caused by wounds of skin flap grafting.

OBJECTIVE: To explore the mechanism of Baisuifang Granule in treating cognitive malfunction after cerebral infarction. METHODS: One hundred and sixty patients with cerebral infarction were divided randomly into two groups. Eighty patients were treated with Baisuifang Granule and 80 with nimodipine for two months. Clinical observation and laboratory examinations were performed for Mini-Mental State Examination (MMSE), clinical symptoms, Chinese Stroke Scale (CSS), hemorrheological indexes and fibrinogen before and after the treatment. RESULTS: Baisuifang Granule could improve MMSE, reduce the scores of clinical symptoms and CSS, and meliorate the blood rheology. The total effective rate for clinical symptoms in the Baisuifang treated group accounted to 76.25%, with statistical difference comparing to 58.75% of nimodipine treated group (P<0.05). There was significant difference in symptom integral, CSS and whole blood viscosity at the high shear rate, respectively (P<0.01). CONCLUSION: Baisuifang Granule is an effective Chinese medicine for treating cognitive malfunction after cerebral infarction.

Objective To evaluate the capacity for noncommunicable diseases(NCDs)prevention and control in the Centers for Disease Control and Prevention(CDCs)in China. Methods All CDCs in China, including provincial, city and county CDCs were surveyed by questionnaires designed by China CDC including resource provided, capacity and efforts for NCDs. Results(1)Resource: 7483 staff members worked on NCDs prevention and control, only accounting for 4.0% of all the CDCs' personnel; 23.6% of the staff members devoted their time to NCDs control less than 6months in 2008. Fundings for NCDs prevention and control only accounted for 2.29%, 1.70% and2.69% of the total funds of provincial, city and county CDCs, respectively.(2)Capacity: The proportions of CDCs that had professional institutes of NCD at provincial, city and county level were 100.0%, 62.8% and 43.7% respectively. CDCs mainly cooperated with health agencies regarding NCDs prevention and control programs. 34.7% of the staff members had educational background of college undergraduate or higher, 12.1% had senior professional titles, 61.7% of them worked for NCDs less than 5 years. The average person-times of continuing education in NCDs were 21.90,4.60and 1.68 at the provincial, city and county CDCs respectively. 8.7% of the CDCs sent their staff members for advanced studies on NCDs. All provincial CDCs carried out surveillance but only 4.2%of them published reports of NCDs in all the CDCs during the past three years.(3)Efforts: 43.5% and 30.8% of the county CDCs carried out surveillance and intervention of NCDs respectively in 2008.Conclusion Resources for NCDs prevention and control were quite limited in CDCs. Fundings and staff members for NCDs were not enough, compared to the heavy disease burden of NCDs. Capacityfor NCDs prevention and control need to be improved.

OBJECTIVETo investigate the clinical features in children with tuberous sclerosis complex (TSC)-associated cardiac rhabdomyomas (CRM).

METHODSThe clinical data of 15 children with TSC complicated by CRM were collected. The clinical features of the patients were analyzed, and TSC gene mutations were detected.

RESULTSEleven cases (73%) developed multiple CRM. The majority of the tumors were located in the left and right ventricles. Most tumors presented as a round-like hyperechogenic mass with a clear margin on echocardiography. Arrhythmias occurred in 3 patients and 2 patients experienced heart failure. Gene mutation tests were performed in 2 patients, and pathogenic mutations were detected in both patients, which were TSC1 mutation and TSC2 mutation, respectively. Three patients were followed up for 6 to 38 months, and their CRM shrank or regressed spontaneously.

CONCLUSIONSTSC-associated CRM is generally multiple. Heart failure and arrhythmias may occur in some patients. Echocardiography is important for diagnosis of CRM. TSC-associated CRM has an inclination to spontaneous regression. TSC can be diagnosed at a molecular genetic level by TSC gene mutation detection.

Objective To explore the effect of iodine excess on bone metabolism in experimental autoimmune thyroiditis (EAT) rats. Methods We selected 36 female Lewis rats with body weight of (131 ± 15)g,and divided them into 3 groups randomly: control group, EAT group and EAT + high iodine group, assuring 12 rats in every group. These rats were fed fodder with different concentration of iodine(0.9,0.9, 18.0 mg/kg), and rats in EAT group and EAT + high iodine group were immunized with pig thyroglobulin(pTG) and complete Freund's adjuvant(CFA) to create EAT model. After two weeks, the pathological changes of the thyroid tissues were observed,and the serum thyroid autoantibody[thyroglobulin antibody(TGAb) and thyroid microsomal antibody(TMAb)], the thyroid hormone levels[triiodo thyronine(T3) and thyrine(T4)] and some relevant data of bone metabolism[bone gla protein (BGP), tartrate-resistant acid phosphatase (TRAP), C-terminal propeptide of type Ⅰ procollagen (PICP),C-terminal telopeptide of type Ⅰ collagen (ICTP), insulin-like growth factor- 1 ( IGF- 1 ), osteoprotegerin (OPG) and receptor activator of NF-κB ligand (RANKL)] were measured. Results Inflammatory cell infiltration and local follicular structural damage were observed in the thyroid tissues of EAT rats in EAT group and EAT + high iodine group, and the pathological changes of EAT + high iodine group were mainly thyroid follicular expansion and integration. The level of serum TGAb, TMAb, T3 and T4 of EAT rats in EAT group and EAT + high iodine group[ (63.01 ± 12.36)%, (60.62 ± 11.24)%, (3.78 ± 1.43), (125.12 ± 16.00)pmol/L and (75.00 ± 15.44)%,(72.15 ± 15.00)%, (3.69 ± 0.91 ), (149.40 ± 20.67)pmol/L] were higher than those of the control group[ (4.47 ±1.04)%, (5.73 ± 1.01 )%, (0.75 ± 0.12), (76.91 ± 9.30)pmol/L, all P ＜ 0.05], and the level of serum TGAb,TMAb and T4 of EAT rats in EAT + high iodine group were higher than those of the EAT group(all P ＜ 0.05).The level of serum BGP, PICP and IGF- 1 in EAT group[ ( 1.70 ± 0.31 ), ( 11.31 ± 1.52) μg/L, (0.31 ± 0.06 ) mg/L]were lower than those of the control group[ (8.60 ± 0.33), (14.28 ± 3.10)μg/L, (1.16 ± 0.02)mg/L, all P ＜0.05], and the level of serum TRAP, ICTP, OPG and RANKL[ ( 19.88 ± 3.60)ng/L, (2.43 ± 0.82), (22.36 ± 2.80),( 1.35 ± 0.23 )μg/L] were higher than those of the control group[ ( 14.57 ± 3.56)ng/L, (0.50 ± 0.20), (1.61 ± 0.34),(0.10 ± 0.02)μg/L, all P ＜ 0.05]; compared with EAT group, the level of PCIP and OPG in EAT + high iodine group [ (8.03 ± 1.84), ( 16.80 ± 3.79)μg/L] were obviously decreased(all P ＜ 0.05). Conclusions The reinforcement of differentiation and maturation of osteoblast in the EAT rats results in the increasing of bone resorption. The activity of osteoblast and osteoclast of the EAT rats are inhibited by excessive iodine, showing a low conversion-type osteoporosis.

OBJECTIVETo evaluate the efficacy of hepatitis B viruse (HBV) vaccination and its influencing factors among children in rural area of Jiangsu province.

METHODSTwenty-five hundred and twenty-two children born after 1998 in rural area were selected as the study population using multistage cluster sampling method. HBsAg and anti-HBs were detected by enzyme linked immunoassay (ELISA) and radio-immunoassay (RIA), respectively. Anti-HBs negative children were boosted using different hepatitis B vaccines and the efficacy was compared. Factors causing HBV infection in HBsAg positive children were also investigated.

RESULTSHBsAg positive rates in 1-7 year olds were 0.28%-1.28%, and the anti-HBs positive rates decreased from 76.7% to 45.5%. The HBsAg positive rate in children not timely vaccinated was significantly higher than those with HBV vaccine injection within 24 hours after birth (1.4% vs. 0.5%, P = 0.031). More than 90% of the anti-HBs negative children had protective level of anti-HBs after boosted with HBV vaccine.

CONCLUSIONHBsAg positive rate in children born after 1998 in rural area of Jiangsu province decreased significantly, with an average of 0.8%. The reason for HBsAg carriage in children might be attributed to mother-to-infant transmission or not timely HBV vaccination.

OBJECTIVETo evaluate the kinesis of cellular immunity in adults who were vaccinated with yeast recombinant hepatitis B(rHB) vaccine and the correlation between cellular and humoral immune responses induced by the vaccine.

METHODSEight adults were vaccinated with rHB vaccine according to 0, 1,2 month schedule. The peripheral blood mononuclear cells(PBMCs) were collected at the 3, 8, 21, 34 and 65 days after the first dose. The high purity of CD4+ and CD8+ T cells obtained by sorting from PBMCs were restimulated with recombinant hepatitis B surface antigens (rHBsAg) or peptides. The spot forming cell (SFC) of IFN-gamma, IL-2 and IL-4 of CD4+ and CD8+ T cells were detected by enzyme-linked immunospot (ELISPOT).

RESULTSThe characteristics of IFN-gamma, IL-2 and IL-4 of CD4+ and CD8+ T cells appeared different after immunization with rHB vaccine. IFN-gamma of CD8+ and CD4+ T cells could be detected early with stable SFC, while the IL-2 and IL-4 of CD4+ T cells appeared late but increased after the second and third dose of vaccination. The positive rate of IL-4 of CD4+ T cells were significantly correlated with the positive rate of anti-HBs, while the SFCs of IL-4 and IL-2 of CD4+ T cells were also significantly related to the titers of anti-FIBs.

CONCLUSIONIFN-gamma could be detected early after rHB vaccination in adults, and the positive rates of IL-4 and IL-2 were correlated with that of anti-HBs.
