Objective To study the value and significance of transcutaneous oxygen saturation monitoring from different parts in early diagnosis of neonatal critical congenital heart disease. Methods The transcutaneous oxygen saturation in right upper extremities and right lower extremities of neonates born in our hospital from July 2010 to July 2015 were detected at 2 hours to 24 hours after birth. If the transcutaneous oxygen saturation ≤ 0. 95 or difference between upper and lower extremities≥0. 03, color doppler ultrasound echocardiography were done. Results There were 24 385 cases of newborns in our study. 1 680 newborns with abnormal transcutaneous oxygen saturation ( ≤0. 95 or difference between upper and lower extremities ≥0. 03) were examined with color doppler ultrasound echocardiography. 204 cases of congenital heart disease (12. 1% ) contain 9 cases of critical congenital heart disease ( 0. 5% ) were detected. The critical congenital heart disease included complete transposition of great artery ( n = 3), tetralogy of Fallot ( n = 4), artery malformation ( n = 1), and pulmonary atresia with right ventricular dysplasia ( n = 1 ) . Conclusions Transcutaneous oxygen saturation monitoring from different parts has a high value for early detection of critical congenital heart disease in the newborn. It is recommended for clinical use in grass-roots hospitals.

Objective To explore the effects of donor dendritic cells(DC)treated with Ad-IL- 12p35siRNA on the survival of allogragft recipients.Methods The recombinant adenoviral vectors carrying IL-12p35siRNA and HKsiRNA were transfected into bone marrow derived DC of BALB/C murine.C57BL/6 recipients were infused with DG(Ad-IL-12p35siRNA DC,Ad-HKsiRNA DC and control DC)from BALB/C donors 7 days before cardiac allograft,the survival time of murine and the change of T_H 1 and T_H2(IL-2,IL-4,IL-10 and IFN-?)cytokine were observed.Results The survival time of p35 group(20.17?2.71)days was longer than that of control group(7.81?1.61)days and HK group(7.17?1.60)days.The concentration of IL-2 and IFN-?in p35 group were significantly lower than those of control group and HK group,otherwise were the concentration of IL-4 and IL-10. Conclusion Pretreatment of dondor dendritic ceils with Ad-IL-12p35siRNA could prolonged cardiac allograft survival in recipicents.

Objective To evaluate the efficacy and safety of bladder hydrodistention for the treatment of ketamine-associated bladder dysfunction.Methods Six patients were required to withdraw the ketamine and treated with bladder hydrodistention therapy and sodium hyaluronate irrigation,and medicine to pretect liver and kidney was also used.Results The biopsies of 6 cases demonstrated the cystitis through biopsy.Lower urinary tract symptoms such as urgency,thamuria and odynuria were significantly relieved after bladder installation within 30 days.The O'Leary-Sant ICSI scores and the ICPI scores reduced to 3.5 ± 1.6,2.8 ± 1.5 respectively.The functional bladder capacities increased to an anverage of (180 ± 28)ml,.2-3 times of nocturia,Qmax (14.4 ± 4.3) ml/s.All cases were followed up for 4 to 18 months.Symptoms disappeared or were significantly relieved in all patients.Conclusion Contracture of bladder might be the main presentation of ketamine-associated bladder dysfunction.Intravesical hydrodistention therapy and sodium hyaluronate irrigation could be the safe and effective therapy in the treatment of katamine-associated dysfunction.

Objective To assess metabolic alterations in the human basal ganglia area during maturation and aging by using 2D chemical shift imaging (2D CSI) of proton magnetic resonance spectroscopy (1H-MRS). Methods Seventy healthy subjects were examined by 2D CSI. 2D CSI imaging acquisition was performed in the bilateral caudate, lentiform and thalamus. 1H-MRS was processed to determine the metabolite ratios, including NAA/Cho, NAA/Cr, Cho/Cr. Seventy healthy subjects were divided into 3 groups:20 to 39 years of age group, 40 to 59 years of age group and 60 to 87 years of age group. The three groups of healthy participants were compared. Results There was a significant decrease with aging in the NAA/Cho ratio in the bilateral lcntiform, thalamus and left caudate, and a significant decrease with aging in NAA/Cr ratio in the bilateral thalamus,right lentiform and left caudate (P<0.05), whereas the Cho/Cr ratio was significantly increased in the bilateral lentiform with aging(P<0.05). Conclusions The results of 1H-MRS show significant changes in the level of metabolites during the process of aging. This technique may play an important role in clinical studies and applications for various conditions of metabolic disorders of the human brain.

OBJECTIVETo compare postoperative blood loss under different negative pressures of drainage after total hip arthroplasty for the treatment of femoral neck fractures.

METHODSFrom January 1st to December 30th 2013, 74 patients with femoral neck fractures treated with total hip arthroplasty were randomly divided into two groups: high negative pressure drainage group and low negative pressure drainage group. In high negative pressure drainage group, there were 34 cases including 10 males and 24 females, with a mean age of (75.94 ± 9.02) years old, and the patients were treated with 60 kPa negative pressure of drainage. In the low negative pressure drainage group, there were 40 cases including 13 males and 27 females, with an average age of (74.93 ± 8.90) years old, and the patients were treated with 30 kPa negative pressure of drainage. The amount of total drainage, total blood loss, and hemoglobin change were compared between these two groups.

RESULTSAll the patients got primary healing without infections. In high negative pressure drainage group,the change of hemoglobin was (41.74 ± 15.69) g/L, total blood loss was (1,217.73 ± 459.50) ml and the drainage volume was (312.94 ± 103.44) ml; while in low negative pressure drainage group,the results were (34.90 ± 12.90) g/L, (904.01 ± 381.58) ml and (129.25 ± 44.25) ml separately. All the results in high negative pressure drainage group were higher than those in the other group. Three days after operation, the change of hemoglobin was (46.00 ± 13.29) g/L and total blood loss was (1,304.72 ± 421.75) ml; while in low negative pressure drainage group, the changes of hemoglobin was (43.87 ± 11.39) g/L and total blood loss was (1,196.78 ± 344.20) ml; there were no statistically significant differences between two groups.

CONCLUSIONWhen placing drainage devices after total hip arthroplasty for the treatment of femoral neck fractures, the level of negative pressure should be chosen according to preoperative level of hemoglobin and HCT in patients. For old patients with femoral neck fracture, low negative pressure is more suitable.

Objective To observe the early outcome and crisis onset after surgical treatment on myasthenia gravis with thymoma and analyze the relevant factors.Methods 436 patients with myasthenia gravis were treated surgically between January 1999 and Jan- uary 2005,58 patients with thymoma.The severity of MG disease was classified according to modified Osserman classification:type Ⅰ(n=17),type Ⅱ a(n=23),type Ⅱ b(n=12)and type Ⅲ(n=6).The distribution of thymomas by the Masaoka clinical stage showed 30 in stage Ⅰ,18 in stage Ⅱ,7 in stage Ⅲ and 3 in stage Ⅳ.The early outcome and crisis onset after surgical treat- ment were analyzed by statistical methods.Results After operation,symptoms improved in 16 eases(27.59%),no change in 18 eases(31.03%),deterioration in 11 cases(18.97%)and crisis onset or death in 13 cases.Logistic test showed that the possibility of crisis onset in patients with thymoma is 1.286 times higher than patients without thymoma.Patients with thymoma,type Ⅱ or above are in high risk group of crisis.The incidence rate of crsis in type Ⅱ group or above was significantly higher than type Ⅰ(P=0.048 0.05).Conclusion The risk of crsis onset after operation significantly raises in myasthenia gravis patients with thymoma.The staging of the disease are associated to development of crisis and crisis onset is independents to patho-staging of thymoma.

Objective To review the safety and efficacy of upper-pole access percutaneous nephrolithotomy (PCNL). Methods From May 2008 to May 2010,237 cases ( 135 males and 102 females with mean age of 42 yrs) of renal or proximal ureteral calculi treated with upper-pole access PCNL were reviewed.The indications included calculus larger than 1.5 cm or impacted proximal ureteral calculi in 94 cases,calculus≥2 cm or impacted renal pelvic calculi in 26 cases,staghorn or multiple calculi in 68 cases,complex lower calyx calculi in 13 cases,upper calyx calculi not amenable to ESWL or URS in 12 cases,calculi within upper calyx diverticulum in 3 cases,combined UPJ obstruction or upper ureteral stenosis in 8 cases,morbidly obese patients in 3 cases,calculi within horseshoe kidneys in 6 cases,calculi within transplanted kidneys or ureters in 4 cases.Of the 237 cases,175 tracts (73.8％) were above the 12th rib,46were above the 11th rib,12 were below the 12th rib,4 were in the lower abdomen for renal transplant patients. Results The overall stone clearance rate with upper-pole access PCNL monotherapy was 74.3％.Additional punctures were required in 55 cases and combined ESWL in 6 cases.Total stone clearance rate at 3 months after operation was 88.2％.16 patients (6.8％) had a pleural injury.Thoracentesis was required in 8 patients,closed thoracic drainage in 5 patients,conservative treatment in 3 patients.After nephrostomy tube removed,pleural irritation symptom appeared in 12 cases (5.1％) who required symptomatic treatment.No patient had injury to the lung or other viscera.Significant bleeding requiring blood transfusion was olserved in 5 patients,while selective renal arterial embolization was required in 2 cases. Conclusions Upper-pole access offers optimal visibility,convenience for the movement of rigid nephroscope and high stone-free rate.It should be attempted in selected cages of upper ureteral calculi and complex renal calculi.

Objective To observe the influence of nursing intervention on postpartum depression and breastfeeding compliance in primipara.Methods From August 2013 to April 2015,146 women received cesarean section in North Jiaochang Branch of Hanzhong Central Hospital were randomly divided into intervention group and control group with 73 cases in each group.The control group was treated with routine nursing measures,and the intervention group with both routine care and nursing intervention.Self-Rating Depression Scale (SDS) and Self-Rating Anxiety Scale (SAS) were used to evaluate the negative emotions of maternal postpartum.Breastfeeding Self-Efficacy Scale (BSES) were used to evaluate the confidence of maternal breast feeding.The breast feeding compliance between the two groups was compared.The breast feeding rates of the two groups were compared in 1 week and 1 month after discharge.Results Compared with the control group,the SDS and SAS scores of the intervention group were significantly lower (P＜0.05).The breastfeeding confidence of the intervention group was significantly better than the control group and the difference was statistically significant (P＜0.05).The compliance of breast feeding of the intervention group was 97.26％ significantly higher than that of the control group (78.08％)with a statistically significant difference (P＜0.05).After one-week and one-month follow-up,the rate of breastfeeding of the intervention group was significantly higher than that of the control group (95.89％ VS 83.56％;91.78％ VS 72.60％,P＜0.05).Concltsion The nursing intervention measures for primipara after cesarean section can significantly break bad mood,enhance maternal breastfeeding confidence,increase the rate of breastfeeding compliance and are worthy of promotion.
