Objective To compare the diagnostic value of prenatal ultrasound with magnetic resonance imaging(MRI)in the abnormalities of fetal urinary reproductive system,and explore the value of combining prenatal ultrasound and MRI in diagnosis of fetal urinary and reproductive system abnormalities.MethodsTwenty-seven fetal abnormalities in urinary reproductive system detected by prenatal ultrasound received MRI examination within 24 hours after ultrasound,confirmed by autopsy or clinical follow-up.The results of prenatal ultrasound and MRI were analyzed retrospectively.Results Ultrasound,MRI,autopsy or after birth,postpartum follow-up confirmed 27 cases of Genitourinary system anomalies,including 2 cases of hydronephrosis,renal agenesis in 6 cases,14 cases of renal cystic disease,renal fusion in 3 cases,1 case of renal tumors,ovarian cyst in one case of crown .Fetal ultrasound can diagnose the majority of the genitourinary system anomalies (25/27),MRI can diagnose fetal anomalies of 26 cases of genitourinary system.Conclusion Ultrasound could diagnose the majority of fetal abnormalities in urology reproductive system accurately.However,combining ultrasound and MRI could establish more precise estimation in urology reproductive system,such as the level of obstruction of urinary system in hydronephrosis,the pulmonary hypoplasia secondary to urology system abnormalities,and location of cyst in the renal parenchyma or in the renal capsule.

Objective To evaluate the effects of an intervention programme of health education and life style modification on postmenopausal osteoporosis women. Methods A total of 120 postmenopausal osteoporosis women were enrolled in this one-year randomized controlled follow-up study and assigned to the intervention group ( Group A, n = 60) or the control group ( Group B, n = 60). Both groups were treated with alendronate sodium. In Group A, education program was performed once a season in the form of face-to-face consultation or group session. In Group B, no additional intervention was used. The primary outcome was patients' compliance in follow-up. The secondary outcomes were change in bone mineral density (BMD).BMD was measured by dual-X-ray absorptiometry (DXA) on lumbar spine and hip at baseline and 12 months after the intervention. Results After one-year intervention,51 subjects in Group A and 38 in Group B completed the follow-up. Groups A showed better compliance. BMD on lumbar spine and hip was significantly increased in both groups when compared with baseline. The changes of BMD on lumbar (0.042+0.067 vs 0.026±0.070,P=0. O29) or Words region (0.029 +0. 129 vs 0.023±0. 143,P=0. 041 ) showed statistical significance between the two groups. Conclusion For alendronate sodium treatment, health management ensures the effectiveness of the therapy and improves the compliance of the patients.

Objective To analyze the controlled risk factors of osteoporotic vertebral fractures, and determine the clinical value for the management of risk factors. Methods 626 cases of postmenopausal women were selected, age, height, weight and bone mineral density(BMD) of patients were collected.The Tetrax balance test system was used to assess the fall risks.Vertebral changes of patients were evaluated through X ray of thoracolumbar lateral. The clinical data were analyzed and compared between vertebral fracture group and non-vertebral fracture group. Spearman test was used to analyze the correlation between vertebral fracture and age, height, weight, body mass index(BMI), the risk of fall, body fat and BMD. Results 328 patients presented with osteoporotic vertebral fractures, while the other 298 cases did not suffer from osteoporotic vertebral fractures. There were 426 vertebral bodies involved. Comparing to non-vertebral fracture group, the vertebral fracture group showed higher age [(68.67±9.29)years vs.(63.04± 9.30)years], lower height[(151.10 ± 4.39)cm vs.(154.90 ± 5.86)cm], lower bone mineral density[lumbar spine BMD (0.85 ± 0.16)g/cm2 vs.(0.93 ± 0.17)g/cm2, hip spine BMD (0.72 ± 0.18)g/cm2 vs.(0.81 ± 0.13)g/cm2],higher body fat [(41.30 ± 5.20)％vs.(36.30 ± 5.90)％] and higher fall risk (41.38 ± 25.79 vs. 36.20 ± 26.22) ( P<0.001). While there were no statistical differences in weight and BMI between the two groups, age, height, BMI, body fat, fall risk, lumbar spine and hip BMD were significantly correlated with vertebral fracture (r=0.358,-0.323, 0.169, 0.186, 0.135,-0.398,-0.364, respectively, all P<0.001). Conclusions Decreased bone mineral density, increased age, abdomen fat content and increased fall risk, are the risk factors of osteoporotic vertebral fractures.

Objective To compare different surgical techniques and clinical effectiveness using infrahyoid myooutaneous flap to restore effects after intraoral cancer surgery.Methods It is a retrospective study in Sichuan cancer hospital, from May 1994 to March 2007, 27 cases were treated surgically with unilateral infrahyoid myocutaneous falp, 19 males and 8 famales.Seven cases of squamous cell tongue carcinoma, 4 eases of tongue root carcinoma, 16 cases of mouth floor carcinoma- The biggest flap was 4 cm × 8 cm.In 8 cases, the flap was formed since the remote end reverse vascular traveling and carried with inferior 1/3 muscular tissue of the stemocleidomastoid muscle on the same side (retrograde flap forming), in 19 cases, vascular pedicla was anatomied with microscopic blood vessel-operating skills along vascular traveling before the flap forming( anterograde flap forming).Eleven cases of the reservation vascularized and infrahyoid muscles in the hyoid attachment (combination pedicle), in 16 cases, the arteria and vena thyroidea superior reserved as the pedicel accompanied with the vena jugularis anterior ( the axial vessle pedicle) ; in 21 cases, the distal end of the vena jugulafis interna was tied up at the place where the vena facialis communis joins to the vena jugularis interna, and the vena jugularis anterior was reserved within the flap ( interference return).Results The survival rate of total 27 cases are 77.8%.The flap necrosis in two cases of total group, 1/3 - 1/2 skin necrosis of the flap was found in 4 cases, in the six cases, flap was formed with retrograde flap forming carry with the ipsilateral sternocleidomastoid, the reason of necrosis was venous flow obstruction.Twenty-one flaps of interference return are all survived, the flap in 19 cases with anterograde flap forming all survived, and 16 cases of the axial infrahyoid flap all survived.Follow-up nine months to 13 years with a median follow-up time for four years.Lost four cases, 23 followed up cases did not found on the flap recurrence of cancer.The primary tumor recurrence in three cases, six cases of cervical lymph node recurrence, Kaplan-Meier method statistics 3,5-year survival rates were 69.8%, 47.2%, respectively.Conclusions To improve the survival rate, the surgical approach of anterograde flap forming is suitable, to anatomize the axial vessle pedicle with microscopic skills, in particular should pay attention to ensure that venous return.Carrying with the same side of the sternocleidomastoid muscle tissue and retaining hyoid attachment of infrahyoid muscles will not increase the survival rate of the muscle flap.

Objective To investigate the effect of once yearly zoledronic acid of 5 mg on postmenopausal women with osteoporosis of different causes. MethodsFrom October 2009 to December 2009,a total of 89 postmenopausal women with osteoporosis were enrolled and assigned into 2 groups.There were 45 cases of primary postmenopausal osteoporosis,including 27 cases of fresh fracture,in group A.They were aged from 47 to 83 years,with an average of 63.7 years.There were 44 cases of secondary postmenopausal osteoporosis,including 28 cases of fresh fracture,in group B.All patients were given a.single 30-minute intravenous injection of zoledronic acid (5 mg),supplemented by 1,25-dihydroxyvitamin D of 0.25 μg and calcium of 600 mg with VitD125 IU daily.At pre-intervention and 12 months after intervention respectively,bone mineral density (BMD) was measured by dual-X-ray absorptiometry (DXA) at the lumbar spine and hip,and a balance test(Sunlight Tetrax- Ⅱ) was performed to evaluate the risk of falling.Intervention compliance of the patients and adverse events related to zoledronic acid infusion were observed. Results All cases of fresh fracture healed well at 3-month follow-up.At 12 months,43 subjects in group A and 42 subjects in group B completed the follow-up.In group A,BMD increased by 5.8％ at the lumbar spine,by 2.9％ at the femoral neck,by 5.2％ at the Words area,by 5.3％ at the greater trochanter and by 3.9％ at the total hip while the risk of falling decreased by 26.1％; in group B,BMD increased by by 3.4％ at the lumbar spine,by 2.1％ at the femoral neck,by 3.2％ at the Words area,by 3.0％ at the greater trochanter and by 2.5％ at the total hip while the risk of falling decreased by 21.8％.The differences between pre-intervention and post-intervention were significant in both groups ( P ＜ 0.05).No intolerable adverse events occurred in both groups except that one new fracture happened in each group but responded to conservative treatment.ConclusionA once-yearly infusion of zoledronic acid of 5 mg is a convenient and effective therapy for treatment of osteoporosis in postmenopausal women.

ObjectiveTo investigate the effects of caleitriol,training on balance and lower extremity muscle strength on fall risk of postmenopausal women with osleoporosis or osteopenia.Methods A total of 200 postmenopausal women with osteoporosis or osteopenia,whose balance test confirmed higher fall risk,were randondy assigned to group A or B.Those of group A received the following intervention:( 1 ) 0.25 μg calcitriol,QD; (2) general information on fall and osteoporosis; (3) balance training; (4) lower extremity muscle strength exercises.Those of group B were only treated with 0.25 μg calcitriol.All the participants were supplemented with 600 mg/d calcium and 125 IU/d vitamin D.Fall index,bone mineral density,serum levels of calcium and phosphorus,and adverse reactions were record.Results After 3 months' intervention,the fall index of both groups was significantly decreased ( group A:t =2.16,P＜0.05 ; group B:t =2.08,P＜0.05 ).After 6 months' intervention,the fall index of both groups went on decreasing,and significant difference of fall index between 6 month and baseline of group A and between group A and group B at 6 months was found.After 1-year intervention,the fall index of group A was further decreased in comparison with group B ( t =2.66,P＜0.05 ).No hypercalcemia occurred during the study period.Conclusion The fall risk of the patients with postmenopausal osteoporosis or osteopenia was reduced after 3 months' intervention.Twelve months' active vitamin D intervention could either reduce the risk of fall or improve bone mineral density.Patient education,balance training and muscle exercise may be effective intervention to reduce fall risk.

Objective To study the association of liver fat content (LFC) with insulin resistance and β cell function. Methods One hundred and nine subjects including 31 cases with impaired glucose regulation (IGR), 31 newly diagnosed type 2 diabetes (NT2DM) and 47 normal controls (NC) with normal metabolic parameters were involved in the study. LFC was measured by 1H magnetic resonance spectroscopy (1H MRS) and the insulin resistance and β cell function were evaluated by oral 75 g glucose tolerance test. Results (1 ) LFCs were3.83% (2.35% ～7.59% ) ,12. 82% (8.10%～21.37%), and 21.99% (11.89%～34.43%), being progressively raised in the respective NC, IGR, NT2DM groups(P<0.01). (2) The subjects were divided into four subgroups according to LFC Quartile: Quartile 1 (LFC<4. 04% ) , Quartile 2(4. 04% ≤LFC<9. 77% ), Quartile 3 (9.77% ≤LFC<20.78% ) ,and Quartile 4( LFC≥20.78% ). Homeostasis model assessment of insulin resistance index (HOMA-IR) values were elevated significantly and progressively starting from Quartile 2(P<0. 01). (3) Insulin from 0 to 30 min ( △I30), the ratio of insulin from 0 to 30 min to glucose from 0 to 30 min ( △I30/ △G30) , C peptide from 0 to 30 min (△CP30) had a trend of increase in Quartile 2,then trended to decrease in Quartile 3. In Quartile 4, △CP30 and △I30/△G30 sharply decreased (P<0.05 or P<0.01). The ratio of C peptide from 0 to 30 min to glucose from 0 to 30 min ( △CP30/△G30) began to decrease from Quartile 3 (P<0. 05). The ratio of area under curve of C peptide to area under curve of glucose (CPAUC/GAUC) was significantly decreased from Quartile 3(P<0.05). From Quartile 3,glucose level became abnormally elevated to impaired fasting glucose and impaired glucose tolerance (P<0.01). (4) LFC was positively correlated with HOMA-IR (rs =0. 618 ,P<0.01), but was negatively correlated with △CP30(rs =-0.282), △CP30/△G30(rs = -0. 404), and CPAUC/GAUC(rs = -0. 308,all P<0.01). (5) Stepwise regression analysis demonstrated that LFC was the strongest predictor of HOMA-IR. Conclusions When LFC accumulated to 4% , insulin resistance occurred and the early phase of insulin secretion was compensatively increased. As the LFC further accumulated to 10% , both the early phase as well as β cell function in whole were deteriorated, and hyperglycemia developed.

Objective To study the influence of different body serum iron levels on follicle stimulating hormone (FSH),luteinizing hormone (LH) and uterine ovarian index,and explore the body serum iron level effects on female mice sexual maturity further.Methods 36 three weeks C57BL/6J female mice were randomly divided into the normal control group,strengthen-iron 1 group and strengthen-iron 2 group,12 cases in each group.The normal control group with normal diet(310mgFe/kg),strengthen-iron 1 group and strengthen-iron 2 group were given high -iron diets(respectively with 465mgFe/kg and 620mgFe/kg) after born 3 weeks.each group body,uterus and ovary mass after 2 weeks were checked;colorimetric method was used to detect the serum iron level;the serum follicle stimulating hormone (FSH) and luteinizing hormone(LH) were detected by chemiluminescent immunoassay.Results The body of mice serum iron levels,uterine ovarian index (uterine ovarian wet mass/body mass) and follicle stimulating hormone(FSH) level of strengthen-iron 1 group and strengthen-iron 2 group were higher than those of normal control group (F =9.11,11.11,7.09,all P ＜ 0.01).Luteinizing hormone (LH) level of the strengthen-iron group was higher than those of normal control group (F =3.89,P ＜ 0.05).Conclusion Uterine ovarian index,follicle stimulating hormone level and luteinizing hormone level were affected with increased serum iron level;It suggests that the increasing serum iron level can cause female mice sexual maturity in advance.

OBJECTIVETo explore, on the basis of principles of bibliometrics, the distribution of the authors of the articles published in Chinese Journal of Pediatrics, and the types of the institutions and the different regions from where the manuscripts were submitted in order to make a clear view of the characteristics and the status of cooperations in pediatric research work; to ascertain, among them, the core authors, core institutes and core regions; and to analyze the significance of corresponding authors, a new regulation adopted by this Journal in recent years, and to explore, furthermore, the funding status of the studies.

METHODBased on the information drawn from Chinese Medical Current Content (CMCC), bibliometric method was used to analyze the publications in Chinese Journal of Pediatrics and their authorship during the period from 1996 to 2005.

RESULTTotally 3337 academic articles were published during the ten years; of which the number of articles written by more than one authors was 2951, accounting for 88.43 %, with a degree of collaboration as 4.12. The number of articles by a single author was 386 (11.57%). A total of 234 core authors contributed to 1031 research papers published (30.90% of all). As for the regions from where the papers were submitted, the top one was Beijing, which had 968 articles published (29% of all). And for the institutes, the number of the papers from the hospitals affiliated to medical schools was 2095 (62.78% of all), ranked the first. The second was research institutes which had 261 articles published in the Journal (7.82%), and 68 articles were from colleges and universities which ranked the third (2.03%). The top 10 institutes in number of papers had published 1273 articles (38.15% of all). The articles, from research projects funded by certain grants published in this Journal increased almost every year, from 7.44% of 1996 to 25.82% of 2005', which reflected timely and objectively a growing tendency in pediatric research and that funded research projects by certain garnts could be an important support to the publication of academic papers. The corresponding authorship as a signature regulation was introduced by this Journal in 1999, which played a positive role in pushing the leading work of key authors in construction of research groups. There were 2243 articles of pediatric clinical studies, (67.22%) and 1094 of basic research (32.78%).

CONCLUSIONChinese Journal of Pediatrics had a wide distribution of authors and a high cooperative rate. This Journal had a group of core authors who were strong in academy, active in research and productive in papers, and had a strong positive impact on this Journal. But it was also revealed that the research powers in the field of pediatric study were not evenly distributed. The guideline adopted by and for this Journal was clear and correct. The articles published in this Journal not only objectively reflected the distribution of the research powers and the latest achievements in pediatric study over the country, but also had its focus, which played a certain leading role in pediatric research.
