Objective To investigate the impact of applying patient-centered care concept on easing the negative moods among the parents of the neonates hospitalized in NICU.Methods The parents of neonates (76 people) hospitalized in NICU from March to May in 2012 were selected as the control group,they conducted normal nursing.The parents of neonates hospitalized in NICU during June and August in 2012 were named as the observation group (81 people).In addition to the normal nursing,they were given nursing intervention according to patient-centered care concept.The anxiety and depression moods of the two groups was analyzed.Results Before the patient-centered care concept intervention,there was no statistical difference of SAS,SDS scores for both groups.For the observation group,the SAS,SDS scores after intervention were significantly lower than those before the intervention.While for the control group,there was no statistical difference of SAS,SDS scores.After intervention,the SAS、SDS scores of the observation group were significantly lower than those of the control group,and the difference was statistically significant.Conclusions The negative moods of the parents of hospitalized neonates can be eased significantly by applying patient-centered care concept intervention.

[Abstract ] Objective Bone marrow mesenchymal stem cells(BMSCs) can be induced to the differentiation into vascular smooth muscle cells in many induction conditions.We sought to explore the possibility of the differentiation of mesenchymal stem cells into vascular smooth muscle cells by continuous cell culture in vitro. Methods Rat BMSCs were isolated from the bilateral tibial and femoral bones by the method of whole bone marrow adherence, followed by ex vivo expansion.BMSCs were identified by flow cytometry and three-lineage differentiation.After continuous five days'cell culture of BMSCs, the specific surface antigens of VSMCs were detec-ted by immunofluorescence, western blot and real-time PCR. Results BMSCs expressed CD29、90, in contrast, they did not express CD45、34、49d.After induction of osteogenesis, adipogenesis and chondrogenesis, alizarin red、oil red and alcian blue staining pro-duced a strong reaction in cells.The expressions ofα-SMA、Calponin1、SM-MHC and SM22 in the cells of experimental group were no-tably increased, which indicated that BMSCs were differentiating towards VSMCs. Conclusion In the absence of exogenous stimula-tion, BMSCs can be successfully induced to differentiate into VSMCs by continuous cell culture.

Objective To study renal involvement in hepatic glycogen storage disease(GSD) in childhood. Methods One hundred and eight patients aged less than 21 years old with type Ⅰa GSD (54 cases), type Ⅲ (29 cases) and uncertain type hepatic GSD (25 cases). Urine analysis, urine albumin, urine protein of 24 h, urine ?_2-MG, BUN, creatinine, Ccr were evaluated. Results Of 108 patients with hepatic GSD, 16 patients (20.8%) had proteinuria proven by urine albumin or urine protein of 24 h, their ages first found proteinuria were 8～15 years. Two 15-year-old patients had proteinuria over 1.0g/24h. Among 72 patients, urine ?_2-MG of 51 cases (70.8%) increased (175～10 623mg/L), and the mean urine ?_2-MG of type Ⅰ a GSD was much higher than that of type Ⅲ GSD, 4138.2 and 1790.1mg/L respectively. Of 91 patients, 10 had renal insufficiency, 1/10 (15-year-old girl) had heavy proteinuria (3.5g/24h), elevated BUN (9.3mmol/L) and Scr(1061 ?mol/L). Five elder patients (11～21 years old) had hematuria with renal colic caused by renal calculus. Conclusions Persistent protenuria, increased urine ?_2-MG, decreased Ccr, and renal stones are common complications of hepatic GSD in childhood. Renal function should be thoroughly evaluated during follow-up.

Objective To explore the role of cell apoptosis pathway in alcoholic pancreatitis.Methods C57BL/J mice were divided into control group (NC) and Alcohol group (AC),Acute pancreatitis group (AP) and Alcoholic acute pancreatitis group(AAP).Alcohol treatment was 10％ w/v ethanol feeding for 2 d,15％ w/v ethanol for 5 d,and then 20％ w/v ethanol until 13 weeks.AP model was established by the intraperitoneal injection of 50μg caerulein/kg body weight once an hour for a total of 7 times.Blood samples were collected for detecting serum amylase and lipase activity.Part pancreatic tissue was collected and the wet and dry weight were both measured to calculate the water content.The routine pathological exanination of the pancreatic tissues were conducted.The expression of apoptosis associated protein caspase3 and caspase8 was determined by Western blot.And cell apoptosis was determined using TUNNEL method.Results The level of serum amylase in NC group,AC group,AP group and AAP group were(3 630 ± 259),(3 196 ± 187),(35 955 ± 4607) and (53 607 ± 3 848) U/L;the level of serum lipase were (502 ± 41),(745 ± 42),(7 346 ± 665) and(12 764 ± 2 544) U/L;the water content were (70.2 ± 3.1) ％,(69.6 ± 2.0) ％,(78.2 ± 1.5) ％ and(85.0 ± 3.0) ％ and (12.75 ± 0.25);the expression of caspase3 were (1.017 ± 0.0784),(1.287 ± 0.097),(178 ± 0.07785) and (0.2443 ± 0.0243);the expression of caspase8 were (0.8289 ± 0.0096),(0.5985 ±0.0735),(1.27 ±0.08) and (0.145 ±0.015);the number of apoptotic cells were 1,6,214,97/10 high power field.The pathological score of pancreas injure in NC group,AC group,AP group and AAP group were 0,0,(7 ± 0.4) and (12.8 ± 0.3),respectively.Serum anylase,lipase,water content and pathological scores in AP group were obviously higher than those in NC group (P ＜ 0.05),which in AAP group were also obviously higher than those in AP group,and all the differences were statistically significant (all P ＜0.05).Compared with NC group,the expressions of apoptosis associated protein caspase3 and caspase8 and the number of apoptotic cells were obviously increased in AP group,which were obviously higher than those in AAP group,but the expression of caspase3 and caspase8 in AAP group were decreased compared with NC group,and all the differences were statistically significant (all P ＜ 0.05).Conclusions Chronic alcohol exposure may aggravate the severity of pancreatitis,and the inhibition of apoptosis pathway and the enhancement of acinar cell necrosis may be involved in this process.

Objective To assess the feasibility,safety and efficacy of endoscopic papillectomy (EP) for tumors at the ampulla of Vater (AV).Methods A total of 15 patients with tumor at AV that were indicated for EP were included in this prospective study.Their clinical profiles,procedural parameters and outcome were evaluated.Results All patients underwent EP procedure successfully.Four patients who were diagnosed as having chronic inflammation in the reference endoscopy were confirmed as having adenoma after EP.Out of the 11 patients who were previously diagnosed as andenoma on biopsy,2 of low differentiated adenocarcinoma,1 of well differentiated adenocarcinoma and 1 malignant transformation were pathologically confirmed after EP.Stents were implanted in 8 patients with dilated pancreatic and/or common bile duct.Except for 2 cases of melena and 2 transient elevated level of blood amylase after EP,no other major complications occurred.Three patients,including 1 case of low-differentiated adenocarcinoma,1 case of malignant transformation and 1 case of lesion residual,were referred to surgery,another patient with low-differentiated adenocarcinoma declined any additional intervention because of old age.In the remaining 11 cases ( 11/15,73.3％ ) including one well differentiated adenocarcinoma,no recurrence was observed during a follow-up period of 23.4 (5 to 47) months.Conclusion EP is a minimal invasive,safe and effective treatment for tumors at AV,which also can provide an accurate staging of the lesion.

In order to investigate the safety and efficacy of endoscopic retrograde cholangiopancreatograpy (ERCP) in liver cirrhosis patients with common bile duct stones, we retrospectively analyzed data of 46 common bile duct stones patients with liver cirrhosis who underwent ERCP between 2000 and 2008. There were 12 cases of Child-Pugh A, 26 cases of Child-Pugh B, and 8 cases of Child-Pugh C. 100 common bile duct stones patients without liver cirrhosis were randomly selected. All the patients were subjected to ERCP for biliary stones extraction. The rates of bile duct clearance and complications were compared between cirrhotic and non-cirrhotic patients. The success rate of selective biliary cannulation was 95.6% in liver cirrhotic patients versus 97% in non-cirrhotic patients (P>0.05). The bile duct clearance rate was 87% in cirrhotic patients versus 96% in non-cirrhotic patients, but the difference was not statistically significant. Two liver cirrhotic patients (4.35%, 2/46) who were scored Child-Pugh C had hematemesis and melena 24 h after ERCP. The hemorrhage rate after ERCP in non-cirrhotic patients was 3%. The hemorrhage rate associated with ERCP in Child-Pugh C patients was significantly higher (25%, 2/8) than that (3%, 3/100) in non-cirrhotic patients (P<0.01%). There was no significant difference between these two groups in the rate of post-ERCP pancreatitis (PEP) and cholangitis. ERCP is safe and effective for Child-Pugh A and B cirrhotic patients with common bile duct stones. Hemorrhage risk in ERCP is higher in Child-Pugh C patients.

Objective To discuss the clinic characters of clear cell papillary renal cell carcinoma ( CCPRCC) and the efficacy of related laparoscopic surgery.Methods From October 2013 to December 2015, 4 cases were treated as CCPRCC including 3 male and 1 female.Their age ranged from 34 to 67 years old ( mean 53 years old) .The duration of illness ranged from 7 days to 3 months, which the average duration was 1.5 months.The location of tumor included left side in 2 cases and right side in other 2 cases.All tumors were found incidentally, without symptoms or positive sign.Ultrasound showed that 2 cases were solid, and the other 2 cases were cystic solid with low, high or mixed echo and rich blood flow signals.The tumors were enhanced in CT arterial phase, and calcification showed in one case.MRI showed heterogeneous signal.The mean size of tumor was 3.0 cm,ranging 2.3 to 4.5 cm.After preoperative examination, all cases underwent retroperitoneal laparoscopic partial nephrectomy.During the operation, 2 cases were confirmed as cystic solid tumors, and the other 2 cases were solid tumors.Renal artery and renal mass were dissociated , then the artery was blocked.The tumor was complete resected, and kidney was sutured. Results All surgery was performed successfully without conversion.The operation time was 137-191 min (average 157 min).The blood loss was 10-100 ml (average 45 ml) without blood transfusion.The warm ischemia time was 15-35 min ( mean 22 min) .The postoperative hospitalization time stay 6-8 d ( average 7 d).Pathologic report was CCPRCC, including 3 cases of WHO/ISUP grade 1, and 1 case of WHO/ISUP grade 2.2 cases were cystic solid tumor, and other 2 cases were solid tumor.Bland-appearing tubules and occasional small papillae, and uniform small nuclei are arranged in a linear manner away from the basal aspect of the tubules in microscope.Immunohistochemistry showed that CA IX, CK7, 34 E12 were positive, but CD10 , P504S and CD117 were negative.The mean duration of postoperative follow-up was 14 months, ranging 4 to 30 months.No recurrence was found in those patients.Patients were followed up for 4-30 months ( average 14 months) without recurrence or metastasis.Conclusions CCPRCC is a rare subtype of renal tumor, which mainly diagnosed by pathological diagnosis . Retroperitoneal laparoscopic partial nephrectomy is an effective method for the treatment with good prognosis.

Objective To investigate the glucose metabolic pattern of brain functional loop in patients with refractory obsessive compulsive disorder (OCD) using 18 F-FDG PET.Methods Eight patients with refractory OCD and 8 age- and gender-matched healthy volunteers underwent 18F-FDG PET brain imaging.SPM software was used for image post-processing and quantitative analysis.Correlation analysis between 18F-FDG uptake and Yale-Brown obsessive compulsive scale(Y-BOCS) score was performed.Results Compared with the controls,the glucose metabolism of bilateral frontal cortices ( including the rectal gyrus,orbital gyrus and cingulate gyrus),left thalamus,right temporal lobe and bilateral cerebellum in refractory OCD patients increased significantly ( Zmax =3.45 - 5.80,all P ＜ 0.001 ).Bilateral motor cortices and bilateral parietal lobes (BA7),however,showed decreased glucose metabolism (Zmax =3.44 - 4.46,all P ＜0.001 ).Y-BOCS score was positively correlated with the glucose metabolism of the bilateral anterior cingulate cortex (Zmax =3.77,3.48 and 2.97,all P ＜ 0.01 ).Conclusions There is a characteristic metabolic pattern of increased glucose utilization in the fronto-striato-thalamic loop and decreased glucose utilization in bilateral motor cortices and parietal lobes in patients with OCD.The glucose metabolism in the anterior cingulate cortex might serve as a quantitative parameter for the assessment of the severity of OCD.

Objective:To observe the clinical efficacy and toxicities of bendamustine hydrochloride in patients with rituximab-re-fractory indolent B-cell non-Hodgkin's lymphoma (NHL). Methods:A total of 25 patients with rituximab-refractory NHL received bendamustine hydrochloride 120 mg/m2 intravenously on days 1 and 2 of the 21-day cycle. The short-term response, progression free survival, and toxicities were evaluated. Results:The total number of chemotherapy of the 25 patients was 122 cycles, and the median number was 5 cycles. All patients could be evaluated for efficacy. Among the patients, 6 had complete remission, 13 had partial remis-sion, 3 had stable disease, and 3 had progression disease. The overall response rate and clinical benefit rate were 76%and 88%, respec-tively. Until the deadline, 13 patients had progression disease. The median duration of response was 8 months, and the median progres-sion-free survival (PFS) was 9.3 months. Subgroup analysis showed that PFS is significantly related to bone marrow involvement and serum LDH level (P<0.05). The main adverse effects were myelosuppression, gastrointestinal reactions, and infection. Rash was found in 2 patients, and 1 case of gastric cancer was discovered after 5 cycles of treatment. Conclusion:Bendamustine hydrochloride was ef-fective and tolerable in patients with rituximab-refractory indolent B-cell NHL.
