Objective To explore the significance and value of Kisspeptin in the diagnosis and therapeutic evaluation for idiopathic central precocious puberty(ICPP) in girls.Methods Twenty-four girls with ICPP and 21 girls with premature thelarche(PT) who were hospitalized in the Children's Hospital of Jiangxi Province from Jun.2012 to Jan.2013 were selected as ICPP group and PT group,and 25 healthy girls were selected as healthy control group.The coagulation vein blood in ICPP girls before treatment and after 6 months treatment and PT girls and healthy girls were collected,and enzyme linked immunosorbent assay was used to detect the plasma Kisspeptin level,and t test was used to analyze the differences among the 4 groups.Results The Kisspeptin level of girls with ICPP [(1.80 ± 0.13) μg/L]was apparently higher than that of PT groups [(1.41 ± 0.10) μg/L] and healthy control group[(1.39 ± 0.13) μg/L],and the differences were statistically significant (t =10.974,14.787,all P =0.000).However,the difference of Kisspeptin between PT group and healthy control group was not statistically significant(t =10.970,P =0.095).In addition,the Kisspeptin level of ICPP girls who undewent 6-month treatment [(1.49 ± 0.15) μg/L] was significantly lower than that before treatment,and the difference was statistically significant (t =10.80,P ＜ 0.05) ;but,compared with PT group and healthy control group,there was no significant difference (t =6.32,P =0.060 ; t =7.44,P =0.214).Conclusions Kisspeptin level is related with pubertal development,and it can be used as an important evidence in ICPP diagnosis and an important parameter in ICPP therapeutic evaluation.

It was previously revealed that noncoding RNAs, especially microRNAs, control cardiac genes and regulate heart function.Recently, growing evidence from high-throughput genomic platforms has confirmed that long non-coding RNAs ( lncRNAs) serve as new and enigmatic regulators in cardiac development and homeostasis.Nevertheless, lit-tle is known about their characteristics compared to microRNAs.Here, we review the latest progress on lncRNAs in cardiac biology and diseases, summarizing detailed knowledge of their functions and novel cardiac-related gene regulatory mecha-nisms in epigenetic processes.Finally, we highlight that lncRNAs could be promising therapeutic targets and diagnostic bi-omarkers in cardiac pathophysiology.

Eighty-nine cases of lumbar intervertebral disc herniation were mainly dealt with acupuncture method, supplementing with traction and Tuina at lumbar region. After 4 courses of treatment, 65 cases were cured, 12 cases got marked effects, 7 some effects, and 3 no effect. This integrated treatment had good effects on lumbar intervertebral disc herniation, and are worthy of being applied widely in clinic.

Due to the dysontogenesis of the arterial duct wall and the abnormal secretion of prostaglandin,symptomatic patent ductus arteriosus is thus often presented in preterm infants.In the past,Indomethacin or Ibuprofen (cyclooxygenase inhibitor) was always chosen to be the interventional medication.While in recent years,Acetaminophen (prostaglandin synthetase inhibitor) has become another therapeutic option for symptomatic patent ductus arteriosus with similar efficacy but less adverse events.The latest research of the mechanism,the therapeutic strategy of time,mode,dosage and duration,the efficacy and the adverse events of Acetaminophen were reviewed.

Opjective To study the prevalence of diabetic nephropathy of type 2 diabetes and its correlated risk factors. Methods 1 059 cases with type 2 diabetes in our university hospital during the period of 1997-2000 were screened for diabetic nephropathy,and its correlated risk factors were analysed. Results The prevalence of diabetic nephropathy and end stage of renal disease were 9.73% and 5.47%, respectively. Hypertension and dyslipidemia characterized with hypertriglycemia and low leve1 of HDL were the main risk factors of type 2 diabetic nephropathy. There was no significant relationship between single-determining HbAlc level and UAER. Conclusion The prevalence of diabetic nephropathy of this study was slightly lower than that reported by other authors in western countries,and the risk factors were consistent with those papers.

Objective To investigate the risk factors for coronary artery lesions (CALs) in children with Kawasaki disease (KD) in Lanzhou. Methods One hundred and seventy-four children with diagnosed KD were divided into CAL group and non-CAL group based on the existence of concurrent CALs. The age, gender, fever duration, intravenous immunoglobulin (IVIG) start time, IVIG dose, C-reactive protein (CRP), serum albumin, erythrocyte sedimentation rate (ESR), platelet (PLT), red blood cell count (RBC), hemoglobin and so on were compared. Results Among the 174 children, 46 children (26.44%) were complicated by CALs and 128 children were not. The differences of average fever duration, IVIG starting time, IVIG dose, PLT, CRP, ESR and RBC were statistically signiifcant (P<0.05). Conclusions When KD children has the fever durations>10 d, start of IVIG af-ter 10 days of fever, increase of PLT, CRP and ESR and decrease of RBC, clinicians should be alert to the risk of concurrent CAL.

BACKGROUND:So far, the pathogenesis of discogenic low back pain is poorly understood. A great diversity of therapeutic means is developed for discogenic low back pain, but the therapeutic outcomes are mixed. OBJECTIVE:To review the research progress in mechanisms and repair of intervertebral disc degeneration in recent years. METHODS: The first author retrieved the PubMed and CNKI databases for relevant articles published before November 2014 using the keywords of “disc degeneration factor, discogenic low back pain, disc degeneration therapy” in English and Chinese, respectively. Initialy, 78 relevant articles were retrieved, but only 30 articles were included in result analysis folowing elimination of duplicate studies. RESULTS AND CONCLUSION:The relatively respected factors for intervertebral disc degeneration include changes in morphology, inflammatory neurotransmitters and the extracelular matrix as wel as role of growth factors. The treatment for intervertebral disc degeneration stil focuses on the morphological restoration. Some surgical therapies, including percutaneous disc decompression, interbody fusion, artificial disc replacement, dynamic stabilization system, have the exact effects on the symptoms due to intervertebral disc degeneration.

Objective:Occult breast cancer (OBC) accounts for 0.3%-1.0%of all breast cancers. Because of the rarity of this dis-ease, its treatment and prognosis remain unclear. Our study evaluated the treatment outcomes and prognostic factors associated with OBC. Methods:A total of 82 patients diagnosed with OBC based on available criteria were treated at the Cancer Hospital of Chinese Academy of Medical Sciences, Beijing, China, between January 1968 and June 2014. Except for 16 patients who were treated by needle biopsy or excisional biopsy only and were subsequently excluded, all of the cases reported were included in the study. Of the remaining 66 patients, one was male. Patient data, tumor characteristics, and treatment and outcome variables were evaluated. Overall survival (OS) and disease-free survival (DFS) were analyzed. A unicentric retrospective review of 66 patients with OBC was performed. Re-sults:The median follow-up was 75.5 months (7.0-328.0). No significant differences in OS and DFS were observed between patients who underwent mastectomy plus axillary lymph node dissection (Mast+ALND) and those who underwent breast conservation surgery (P>0.05). Univariate analysis revealed that nodal status is a significant prognosis factor of DFS (P=0.031). Conclusion:No significant difference in treatment outcomes between mastectomy+ALND and breast conservation surgery was observed. Nodal status may be an independent predictor of poor outcomes in OBC patients.

Objective: To explore the effects of ramipril, trimetazidine and the combination of ramipril and trimetazidine on renal cell apoptosis index (AI) and cytochrome C (Cyt-C) expression in experimental rats with chronic heart failure (CHF).
Methods: CHF model was established by partially banding of abdominal aorta superior to renal artery in experimental rats. A total of 50 male Wistar rats were randomly divided into 5 groups: Sham operation group, Model group, Ramipril group, Trimetazidine group and Combination (ramipril and trimetazidine) group.n=10 in each group. Renal tubular cell AI was examined by TUNEL method, mRNA and protein expressions of Cyt-C were detected by RT-PCR and Western Blot analysis in each group respectively.
Results: Compared with Sham operation group, Model group had increased AI of renal tubular cells, increased mRNA and protein expressions of Cyt-C,P<0.01. Compared with Model group, Ramipril group, Trimetazidine group and Combination group showed decreased AI of renal tubular cells (20.02 ± 1.14) %, (20.10 ± 1.2) % and (14.27 ± 1.40) % vs ( 40.82 ± 1.31) %; reduced Cyt-C mRNA expression (0.54 ± 0.06), ( 0.56 ± 0.05) and (0.44 ± 0.04) vs (0.89 ± 0.03); reduced Cyt-C protein expression (1.50 ± 0.11), (1.58 ± 0.12) and (0.75 ± 0.06) vs (2.53 ± 0.10); the most reduction was obtain by Combination group, allP<0.01.
Conclusion: Ramipril and trimetazidine can inhibit renal cell apoptosis and effectively improve the renal function in CHF rats. Combined medication is better than either of them alone.
