The microRNA let-7 family,functioning as a tumor suppressor,has emerged as a regulator of stem cell differentiation and tumor repression.The RNA-binding protein lin28 is a stem cell pluripotency factor,which contributes to the maintenance of stem cell characteristics and promoting cell malignant transformation.lin28 can block the maturity of let-7 by combining with the precursors of let-7 family miRNAs,which is itself able to repress lin28 by binding to the 3'-UTR of lin28 transcripts,thus forming a feedback loop.The double-negative feedback loop comprising lin28 and let-7 is involved in several biological processes such as differentiation of stem cell,tumorigenesis,invasion and metastasis,drug resistance and relapse,which couldbe a potential target for cancer therapy.

OBJECTIVE:To investigate the optimal administration route of ambroxol in the treatment of pediatric respiratory disease. METHODS:Totally 120 children with respiratory disease in pediatric department of our hospital during Jun. 2014-Jun. 2016 were divided into intravenous dripping group and atomization inhalation group according to even and odd-numbered admission order,with 60 cases in each group. Intravenous drip group was given Ambroxol hydrochloride injection 7.5 mg dissolved in 5%glucose solution 50 mL,ivgtt,bid;aerosol inhalation group was given aerosol inhalation of Ambroxol hydrochloride injection 7.5 mg,for 15 min each time,bid. The two groups were treated with 7 d. Clinical efficacies,p(O2)and p(CO2)level,the times of sputum absorption,clinical indexes and the occurrence of ADR were compared between 2 groups. RESULTS:Total response rate of atomization inhalation group(96.67%)was significantly higher than intravenous dripping group(78.33%);p(O2)level was sig-nificantly higher than intravenous dripping group,while the times of sputum absorption,fever disappearance time,asthma disap-pearance time,oxygen therapy time,pulmonary rales disappearance time,cough disappearance time and average hospitalization time were significantly less or shorter intravenous dripping group,with statistical significance (P<0.05). There was no statistical significance in p(CO2) level and the incidence of ADR between 2 groups (P>0.05). CONCLUSIONS:Ambroxol is effective in the treatment of pediatric respiratory disease,and clinical efficacy of atomization inhalation is better than intravenous drop.

OBJECTIVETo explore therapeutic effects of reconstructing coracoclavicular ligament for the treatment of Rockwood-III Acromioclavicular dislocation by palmaris longus muscle with polyester suture.

METHODSFrom August 2011 to November 2013,37 cases with Rockwood-III acromioclavicular dislocation were treated with reconstructing coracoclavicular ligament by palmaris longus muscle with polyester suture. Among patients, 24 were males and 13 were females, ranging the age from 19 to 46 years old, with an average of 32 years old. There were 11 cases on the left side and 26 cases on the right side. Twenty-nine cases were fresh dislocation and 8 cases were old dislocation. Blood loss, operative time were observed, and Karlsson evaltae standard were applied for assessing postoperative recovery of shoulder joint function.

RESULTSAll patients were followed up from 2.5 to 5 months with an average of 3.5 months. Operative time ranged from 52 to 98 (meaned 72) min, blood loss ranged from 50 to 180 (meaned 75) ml. All operative incision were healed at the satge I . According to Karlsson standard, 32 cases obtained excellent results and 5 cases were moderate.

CONCLUSIONFor Rockwood-III acromioclavicular dislocation,reconstructing coracoclavicular ligament by palmaris longus muscle with polyester suture has advantages of simple operation, and rapid recovery of shoulder joint function.

Objective To compare the clinic effects of suspension and pillow elevation on limb swelling after elbow surgery. Methods One hundred patients receiving operations on elbow fracture were randomly divided into experiment group(suspension elevation)and the control group(pillow elevation)to eliminate limb swelling,50 cases in each group.The forearm circumference(10 cm below elbow)were measured 1-5d after operation,the circumferences on the first day and the fifth day recorded for comparing effects of the limb swelling elimination.Results The circumferences on the 1st day and 5th day of the suspension elevation group and the pillow elevation group were(2?53±0?76)cm,and(4?19±2?36)cm,respectively.The differences in circumference between the two groups were statistically significant(P<0?05).Conclusion The suspension elevation is more effective in promoting venous circulation and eliminating swelling,so it is conducive for the elbow fracture patients in early functional exercise?

Objective To summarize perioperative care and effect of surgical treatment of total anomalous pulmonary venous connection (TAPVC) in newborns and babies within 6 months.Methods From September 2001 to May 2013,ninetytwo consecutive patients with TAPVC received surgical correction under cardiopulmonary bypass (CPB) with moderate or deep hypothermia.The anatomic subtype included supracardiac type 48,intracardiac type 36,infracardiac type 6 and mixed type 2.There were 36 newboms.Pathological diagnosis was made by echocardiogram,computerized tomography and operative findings during operation.The option of procedure was determined by findings.Respirator assisted breathing after operation and cardiac function was maintained by a variety of positive inotropic drugs,to prevent the happening of the pulmonary hypertension crisis.Results Severely low cardiac output syndrome occurred in 8 patients and they died within 24 hours after operation.The remaining cases postoperative recover smoothly and receive postoperative follow-up about 1 month to 12 years,3 cases of postoperative pulmonary vein stenosis (PPVS) occurred.Conclusion Total anomalous pulmonary venous connection should be surgical treatment as soon as possible with satisfied effect.The key of perioperative care is maintenance of left heart function,negative balance of liquid,prevention and treatment of pulmonary hypertension.

To investigate the effect of naringenin on ovariectomy-induced postmenopausal osteoporosis comprehensively and systemically, thirty-two virgin Sprague-Dawley rats about 3-month-old were used and randomly divided into 4 groups: sham control group (Sham), OVX control group (OVX), naringenin treatment group and 17β-estradiol (E2) treatment group. After 12 weeks treatment with different drugs, 24 h urine were collected, organs were weighed and the organ indies were computed. Uterine pathological changes were observed by making paraffin section. Biochemical parameters and bone turnover markers: serum osteocalcin (BGP) and urine deoxypyridinoline (DPD) were analyzed with automatic biochemical analyzer or ELISA assay. Bone mineral density (BMD) and bone mineral content (BMC) were analyzed by DEXA, bone biomechanical properties was measured by three point bending test and the trabecular bone microarchitecture was evaluated by Micro CT. From the results, we can see that: the gaining of weight and the increasing of bone turnover markers such as serum BGP and urinary DPD could be inhibited by naringenin. The treatment could also enhance the bone strength and prevent the deterioration of trabecular microarchitecture, increase the bone volume, trabecular number and thickness, and decrease the trabecular space. The effects mentioned above were not accompanied with stimulating effects on uterus. Long-term using of naringenin had no obvious influence on other organs and the liver and kidney functions. The study suggests that naringenin had obvious antiosteoporotic effect on ovariectomized rats and it had the potential value for the treatment of postmenopausal osteoporosis.
