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 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 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.

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.

OBJECTIVETo observe the effect of low molecular weight heparin calcium (LMWHC) combined Compound Danshen Injection (DI) on nephrotic syndrome patients with early onset severe preeclampsia.

METHODSTotally 80 nephrotic syndrome patients with early onset severe pre-eclampsia were randomly assigned to four groups voluntarily, i.e., Group A (22 cases, treated by magnesium sulfate), B (19 cases, treated by magnesium sulfate plus LMWHC), C (21 cases, magnesium sulfate plus DI), D (18 cases, magnesium sulfate plus LMWHC and DI). Umbilical arterial S/D ratios, amniotic fluid index (AFI), prolonged gestational age, placenta weight, neonatal weight, and Apgar score were compared among the four groups.

RESULTSCompared with before treatment in the same group, umbilical arterial S/D ratios decreased in the four groups (P <0. 05). AFI decreased in Group A, while it increased in Group B, C, and D (P<0. 05). Compared with Group A at the same time point, umbilical arterial S/D ratios decreased, and AFI increased in Group B, C, and D (P <0. 01 , P <0. 05). Prolonged gestational age and neonatal weight were increased in Group B, C, and D (P <0. 01, P <0. 05). Placenta weight were increased in Group B and D (P <0. 05). Apgar scores at 1 and 5 min were improved in Group D (P <0. 05). Compared with Group B and C at the same time point, umbilical arterial S/D ratios decreased, and AFI increased in Group D (P<0. 05). Compared with Group B, prolonged gestational age and placenta weight were decreased in Group C, but prolonged gestational age and placenta weight were increased in Group D (P <0.05). Compared with Group C, prolonged gestational age, placenta weight, and neonatal weight were increased in Group D (P <0. 05).

CONCLUSIONTreatment of nephrotic syndrome patients with early onset severe pre-eclampsia by LMWHC combined DI could prolong gestational ages, obviously improve prenatal outcomes, with better effect obtained than using any of them alone.
