Objective To summarize the nursing methods and effect of artificial femoral head replacement in treatment of osteoporotic interttochanteric fracture in elderly patients. Methods 55 patients with esteoporotic intertrochanteric fracture were selected in our hospital from February 2007 to February 2011.All patients were cared by targeted preoperative and postoperative nursing,helping them conducting functional training in time,giving discharge counseling and follow-up.The hip functional recovery of patients was evaluated by using the Harris evaluation standard,and the excellent rate of surgery was also evaluated. Results After the targeted care,55 patients went through the perioperative period safely,the average length of stay was ( 14.0 ± 3.1 )days,a total of 5 cases (9.09％)patiants suffered varying degrees of complications which were improved after symptomatic treatment.Patients were followed up for 3 to 36 months,only 2 patients died of cerebral vascular accident,all patients gained good recovery of hip function.Harris score was (84.45 ± 9.38),the excellent rate of surgery reached 78.18％. Conclusions Atificial femoral head replacement proves significant effect in treatment of osteoporotic intertrochanteric fractures in elderly patients,but with the accompanying surgical compliuations,special care and timely functional exercise methods should be paid attention to.

Objective To explore the clinical effect of blood purification combined with fasudil in elderly cardiac surgery patients with postoperative acute kidney injury.Methods Fifty elderly cardiac surgery patients with postoperative acute kidney injury were divided into control group and study group by random digit table method with 25 cases each.The 2 groups were treated with routine drug and blood purification,the study group was additionally given fasudil injection 30 mg + 0.9％ sodium chloride injection 50 ml vein pumping,1 time/12 h,for 7 d.The urine volume,urine N-acetyl-β-D-glucosaminidase (NAG),urine γ-glutamyl transpeptidase (γ-GTP),urine α 1-microglobulin (α 1-MG),serum creatinine (SCr),blood urea nitrogen (BUN) and creatinine clearance rate (CCr) were observed,and the acute physiology and chronic health evaluation (APACHE) Ⅱ score was computed.Results There were no statistical differences in the indexes before treatment between the 2 groups (P＞ 0.05).The urine volume after treatment 3,5,7 d in study group was more than that in control group [(38.72 ± 2.68) ml/h vs.(31.68 ± 2.52) ml/h,(47.24 ±3.73) ml/h vs.(40.24 ± 2.52) ml/h、(63.80 ± 2.50) ml/h vs.(56.60 ± 3.30) ml/h],urine NAG,urine α 1-MG,urine γ-GTP,SCr and BUN were lower than those in control group [NAG:(25.05 ±5.44) U/L vs.(28.04 ± 5.21) U/L,(24.06 ± 3.43) U/L vs.(27.23 ± 6.43) U/L,(22.08 ± 3.25) U/L vs.(26.23 ± 4.41) U/L; α 1-MG:(24.05 ± 3.65) mg/L vs.(26.74 ± 6.74) mg/L,(22.98 ± 3.58) mg/L vs.(25.57 ± 3.58) mg/L,(20.95 ± 3.78) mg/L vs.(25.48 ± 3.45) mg/L; γ-GTP:(8.2 ± 0.4) U/L vs.(10.8 ± 3.8) U/L,(7.3 ± 0.2)U/L vs.(10.5 ± 2.5) U/L,(6.5 ± 1.4) U/L vs.(9.7 ± 2.6) U/L; SCr:(206.52 ± 6.72) μ mol/L vs.(255.16 ±6.75) μmol/L,(182.98 ±6.26) μmol/L vs.(252.23 ±9.53) μmol/L,(33.25 ±7.95) μmol/L vs.(170.75 ± 7.94) μ mol/L; BU N:(19.61 ± 3.23) mmol/L vs.(20.25 ± 3.25) mmol/L,(16.76 ± 2.06) mmol/L vs.(18.32 ± 4.84) mmol/L,(12.28 ± 2.26) mmol/L vs.(14.27 ± 4.54) mmol/L],CCr was higher than that in control group [(18.66 ± 3.89) ml/min vs.(13.28 ± 3.25) ml/min,(27.76 ± 4.36) ml/min vs.(16.23 ± 4.18)ml/min,(33.79 ± 5.58) ml/min vs.(22.12 ± 4.65) ml/min],there were statistical differences (P ＜ 0.05).The APACHE Ⅱ score before treatment and after treatment 5,7 d in control group were (32.20 ±4.51),(26.38 ±5.28) and (21.43 ±4.22) scores,in study group were (33.05 ±3.82),(22.15 ±3.42) and (13.25 ± 2.15) scores.There was no statistical difference in the APACHE Ⅱ score before treatment (P ＞ 0.05),the APACHE Ⅱ score after treatment was improved,furthermore APACHE Ⅱ score after treatment 5,7 d in study group were better than those in control group,there were statistical differences (P ＜ 0.05).Conclusions The treatment effect of blood purification combined with fasudil is remarkable in elderly cardiac surgery patients with postoperative acute kidney injury.At the same time,it has high security and very important clinical significance.

ABCC8,KCNJ11,and GLUD1 gene mutations were investigated in a male patient with congenital hyperinsulinism and his parents were also investigated.A 1484 G＞A mutation was found in the 10th exon of ABCC8 gene in the patient,which leads to amino acid substitution at the 495 residue of the sulphonylurea receptor SUR1 protein.The patient's father also carried the same heterozygous inactive mutation,while the genotype of the mother was normal,indicating that the gene mutation of the patient was paternally inherited.According to that mutation,it is deduced that the patient may suffer from the focal type of congenital hyperinsulinism.

KCNJ11 gene mutation was searched in 3 families with neonatal diabetes. A KCNJ11 175 G>A (V59M) mutation was found in one child, while no KCNJ11 gene mutation was found in his parents. No mutation was found in the other two families. The result indicated that KCNJ11 gene mutation might lead to the onset of neonatal diabetes mellitus in Chinese.

Objective To analyze the clinical characteristics of children's Pseudo-Bartter syndrome(PBS) in order to enhance physician's understanding of the disease.Methods Nine children with PBS who were admitted into Beijing Children's Hospital from Nov.2008 to Sep.2013 were selected as research subjects.A retrospective study was carried out with the clinical data and the outcome of treatment.Results 1.Clinical characteristics:there were 9 cases in this group including 5 male and 4 female.The patients' age ranged from 4 months to 8 years 8 months.The most common cause of children's PBS was gastrointestinal symptoms(such as diarrhea and vomiting) induced by respiratory tract infection (7/9 cases).Six patients had no striking clinical manifestations,and hypokalemia was found in the treatment of primary disease.2.Laboratory tests:All of the children in this group had hypokalemia and metabolic alkalosis in varying degrees.The activation of renin,angiotensin and aldosterone system increased.3.Therapy:all children were treated by giving potassium supplemental treatment or indomethacin therapy [1 mg/(kg · d),3 times orally].After treatment,all cases achieved clinical improvement and normal blood electrolytes.All patients' blood electrolytes remained normal for 5 to 7 days after stopping treatment.Conclusions 1.In China,the most common cause of children's PBS is gastrointestinal symptoms(such as diarrhea and vomiting) induced by respiratory tract infection.2.Except for clinical manifestations related to causes,patients have no significant clinical manifestations.Hypokalemia can be found in the treatment of primary disease.3.The biochemical results show low blood potassium chloride with metabolic alkalosis.In PBS renin,angiotensin and aldosterone concentration in blood are all elevated.4.Treatment of children's PBS mainly includes etiological treatment and electrolyte supplement therapy.The treatment effectiveness is good after etiological treatment and potassium supplement treatment.In the condition of controlling etiology and potassium supplementation,electrolytes mas return to normal in 2-4 days.

Objective To analyze the clinical characteristics and the endocrine changes in children with craniopharyngioma,and to improve the pediatrician understanding of the disease.Methods The study subjects consisted of 14 children with craniopharyngioma admitted to the Department of Endocrinology,Beijing Children's Hospital Affiliated to Capital Medical University from Jan.2004 to Dec.2012.All the patients were followed up to analyze the clinical symptoms improvement,endocrine test results and medication,et al.Results The main clinical manifestations were headache (7/14 cases,50.0％),growth retardation(4/14 cases,28.6％),vomiting (4/14 cases,28.6％),polydipsia/ polyuria (3/14 cases,21.4％) and vision diminution (3/14 cases,21.4％).Three patients didn' t undergo the surgery,and 3 cases with diabetes insipidus and 2 cases with growth hormone deficiency,and 1 case with central hypothyroidism by laboratory test.The rest 11 children received surgery and all patients had changes in endocrine after it.Five cases got polydipsia and polyuria,other 5 cases had electrolyte disturbances,and 2 cases had epilepsy.Nine patients were followed up,and the follow-up duration ranged from 5 months to 10 years [(3.29 ± 3.52) years] after surgery.Seven patients got better and 2 patients got worse.Conclusions For clinical symptoms of increased intracranial pressure,changes in endocrine,the vision and visual field,the possibility of craniopharyngioma should be taken into account.Surgery is the main treatment,but it can lead to the damage of hypothalamus and pituitary gland.Changes in endocrine,electrolyte disturbances and epilepsy are the common complications.According to the level of endocrine,longterm hormone replacement therapy for some postoperative patients should be continued.

Objective To investigate the perinatal outcome of fetus with increased nuchal translucency (NT) at first trimester.Methods The thickness of NT above 95th percentile of the fetuses with same crown-rump length (CRL) was set as the criteria of increased NT.The outcomes of fetuses with increased NT during early pregnancy from Jan.2008 to Dec.2009 in Guangzhou Women and Children's Medical Center were followed up.The information of ultrasound at second trimester,pregnant complications and delivery outcome were collected.All infants were followed up for 3 months after birth and were divided into four groups according to their different thickness of NT.The relationship between NT thickness and perinatal outcome were analyzed with single factor analysis of variance and multiple comparison method.Results Among the 178 cases we followed up,there were 2 spontaneous fetal losses and 19 terminations whose reasons were Down syndrome (n=6),severe a thalassemia (n =5),fetal malformations (n =7) and social factor (n =1).Among the 157newborns delivered,one was found with congenital heart disease.The rate of abnormal infants was 11.8％ (21/178) and the detection rate of abnormal infants was 9 5.2％ (20/21).Healthy living rate of fetus with NT thickness between 95th percentile and 2.9 mm was 96.1％ (122/127); 82.4％ (28/34) for those with NT thickness between 3.0 mm and 3.9 mm; and 35.3％ (6/17) when NT≥ 4.0 mm.Conclusions Increased NT might have close relationship with poor pregnant outcome.The thicker the NT,the lower the healthy living rate of the fetus.The pregnant outcome is very poor if NT≤4.0 mm.

Objective To analyze the clinical characteristics of Neonatal Bartter syndrome in order to enhance understanding of the disease.Methods Eighteen children with Neonatal Bartter syndrome who were admitted into our hospital from November 2006 to July 2013 were selected as research subjects.A ret-rospective study was done on the clinical data and the outcome of treatment.Results ⑴Clinical character-istics This group included 13 males and 5 females.The onset age ranged from birth to 1 years 3 months (4.01 ±4.49years).Six cases got the disease after birth.Amniotic fluid which lead to premature birth and low birth weight may happened in cases.The most common clinical symptom was malnutrition (89%).⑵Laboratory tests and Renal ultrasound All of the children showed hypokalemia and metabolic alkalosis in some degree,renin and angiotensin increased.In some cases urinary calcium /creatinine ratio were in-creased and urinary specific gravity,showed a low proportion of urine.Some cases'renal ultrasound exami-nation revealed nephrocalcinosis.⑶ Therapy:All of the patients in this group were given intravenous and /or oral potassium chloride treatment.For drug treatment,10 cases were given single application of indom-ethacin [1 ~3mg/(kg·d),points 3 times per day oral]treatment.Conclusions The incidence of Neo-natal Bartter syndrome was early in infant onset as early as after birth,even the fetal period.Some patients may appear premature birth and /or low birth weigh because of amniotic fluid.The main clinical manifesta-tions include malnutrition,no weight increasing,retardation,serious dehydration and even life-threatening. The characteristic appearance such as the forehead,small jaw,eyes are the important characteristics of neo-natal Bartter syndrome.Patients often appears Hypokalemia,hyponatremia and Hypochloremia.Urinary po-tassium of this type increased.Most children's urinary sodium and chloride increased significantly.

Objective To evaluate the relationship between sternum protection and bone marrow suppression in postoperative radiotherapy for esophageal carcinoma. Methods Total of 98 postoperative patients with thoracic esophageal carcinoma were randomly divided into experimental group (52 cases) and control group (46 cases). All patients were given intensity-modulated radiotherapy (IMRT), with the dose of 50-50.4 Gy. The patients in experimental group were irradiated by 6 fields (4-fields in front, 2-fields behind) which were crossed to avoid direct exposure to the sternum. The patients in control group were irradiated by 5 fields (3-fields in front, 2-fields behind) with front-middle of the field passing through the sternum. Concurrently all patients received 2 cycles of cisplatin chemotherapy. Results Dmean, V20 and V30 of the sternum in the experimental group were (20.21 ±3.60) Gy, (40.78 ±7.19) % and (33.78 ±9.44) %, which were lower than those in the control group [(30.91±5.21) Gy, (81.01±4.81) %, (51.60±6.84) %], respectively (P<0.05). However, the volume and dose distribution of lung, spinal cord and heart were similar between the two groups (P> 0.05). Both the incidence rates of bone marrow suppression at 14th day and 35th day after radiotherapy were significantly higher in the control group (52.2%, 73.9%) than those in the experimental group (28.8 %, 50.0 %) (P< 0.05), and the incidence rate of bone marrow suppression at 7th day after radiotherapy was similar between the two groups. Conclusion Protecting and sketching for sternum in postoperative radiotherapy for esophageal carcinoma can reduce the incidence of bone marrow suppression effectively, which would not increase the radiation dose in the lung, heart and spinal cord.

Aim To investigate the efficacy and mech-anism of FW-04-806 against HER2-positive gastric cancer cell lines,and the combination effect of FW-04-806 with lapatinib. Methods MTT assay was used to assess cell proliferous inhibition of FW-04-806 . The in-hibitory effect of colony formation was tested by colony formation. The protein expression, apoptotic induction and cell cycle arrest were detected by flow cytometry. Co-immunoprecipitation was used to investigate protein-protein interactions. The expression change of proteins was showed by immunohistochemistry. Western blot was applied to reveal the protein expression of related pro-liferous and apoptotic signaling pathway. The tumor growth inhibition was evaluated in tumor xenograft model. Results FW-04-806 obviously inhibited cell proliferation and colony formation in HER2 positive gastric cancer cell lines NCI-N87, OE19, with IC50 of (24. 17 ± 0. 02 ) , ( 29. 61 ± 0. 03 ) μmol · L-1 , re-spectively;FW-04-806 induced G2-M arrest and apop-tosis in a dose-dependent manner;200 mg · kg-1 of FW-04-806 showed tumor growth inhibition of 48. 0%( P < 0. 01 ) . In addition, FW-04-806 dissociated Hsp90/CDC37 complex, followed by degradation of HER2 and Akt,inhibiting the phosporylation of HER2, Akt and ERK, and increasing expression of apoptotic proteins,such as cleaved caspase-3 and cleaved parp. Furthermore,the combination of FW-04-806 with lapa-tinib in vitro was synergistic in NCI-N87 , which en-hanced the inhibition of cell proliferation and increased apoptotic rates. Conclusions FW-04-806 shows po-tent efficacy against HER2-positive gastric cancer cell lines in vitro and in vivo;FW-04-806 is synergistic with lapatinib.
