In most universities the usage of digital information resources are not ideal.One reason is that primary audience groups of libraries——college students rarely use these resources.So we propose some measures and proposals for university libraries to provide the service of digital information resources for university students.

OBJECTIVE: To analyze the clinical features of severe acute pancreatitis (SAP) in aged patients, and to explore the measures of its diagnosis and treatment. METHODS: The clinical data of 100 aged patients (55-85 years old) with SAP admitted from January 2003 to December 2005 were reviewed and compared with those of 221 non-aged SAP patients (11-54 years old) admitted at the same period. RESULTS: Totally 112 times of onset occurred in 100 aged patients, and the main causes for senile SAP were biliary diseases and hyperlipemia. Both acute physiology and chronic health evaluation II (APACHE II) and Ranson scores of the aged patients with SAP were higher than those of the control group (P<0.05); while there was no significant difference in Balthazar score between the two groups(P>0.05). The incidences of low serum calcium, low albumin and high aspartate aminotransferase (P<0.05), liver, kidney or brain impairment as well as the mortality were higher in the senile SAP group than those in the control group (P<0.05). CONCLUSIONS: Biliary disease and hyperlipemia are the main causes of senile SAP, which lacks characteristic clinical symptoms and is often associated with multiple complications such as infection and lung, gastrointestinal tract, liver, kidney, and brain impairment. Individualized differential treatment with integrated traditional Chinese and Western medicine based on stage classification is an effective approach.

Objective To observe the effect of two reverse pedicle flap repaired soft tissue defect of the finger.Methods From April,2011 to March,2015,46 patients were randomly divided into two groups.Twenty-eight cases were performed by dorsal metacarpal artery flaps with cutaneous branches as pedicle and the 18 cases were performed by reverse the proper palmar digital artery dorsal branches island flap.The complication,survival rate,hand function and appearance were analyzed.Results The dorsal metacarpal artery flaps with cutaneous branches as pedicle and reverse the proper palmar digital artery dorsal branches island flap were an average follow-up of 18 and 15 months,all flaps survived.For fingertip defects,8 cases were repaired with as pedicle as the dorsal metacarpal artery flaps with cutaneous branches as pedicle while 16 cases were repaired with reverse the proper palmar digital artery dorsal branches island flap.Among them,complication included 2 cases of early venous congestion and 2 cases of superficial skin necrosis.One case of reverse the digital artery dorsal branches island flap blistered;the flap sensibility was good recovery.The two-point discrimination testing of dorsal metacarpal artery flaps with cutaneous branches as pedicle was from 6.0 to 9.0 mm (average of 7.1 ± 0.5 mm);the two-point discrimination testing of dorsal metacarpal artery flaps with cutaneous branches as pedicle was from 4.0 to 7.0 mm (average of 5.2 ± 0.4 mm),but there were differences in two-point discrimination and there was statistically significant (P ＜ 0.05).There was no significant difference between the two groups each finger interphalangeal joint activity compared with the healthy side.The study found that 10 cases of dorsal metacarpal artery flaps appearance was 5 mm higher than normal skin and 1 patient of reverse the digital artery dorsal branches island flap appearance was 5 mm higher than normal skin,the difference was statistically significant (P ＜ 0.05),the latter was better than the former,especially repaired fingertip defect.Conclusion Dorsal metacarpal artery flaps with cutaneous branches as pedicle and reverse the proper palmar digital artery dorsal branches island flap were safe and reliable,it is the ideal flap finger defects.For finger fingertip defect repaired reverse the proper palmar digital artery dorsal branches island flap is superior dorsal metacarpal artery flaps with cutaneous branches as pedicle.

Objective To investigate the relationship between coronary artery lesions and multiple risk factors in the patients with metabolic syndrome (MS) and coronary heart disease (CHD). Methods Totally 429 patients were definitely diagnosed with CHD by coronary arteriography and their BMI, BP, FBG, TG, HDL-c as well as age, gender, smoking, TC, LDL-c, UA were recorded. All patients were divided into two groups: CHD with MS, CHD. Results BMI, BP, FBG, TG, HDL-c, TC, LDL-c and UA were significantly higher in CHD with MS group than those in CHD group (P

Objective To explore the moisture absorption and related components of aqueous extract of Salviae Miltiorrhizae Radix et Rhizoma. Methods The hygroscopicity of aqueous extract of Salviae Miltiorrhizae Radix et Rhizoma and its water and alcohol elution parts separated by macroporous resin was measured, and the contained low molecular sugars (monosaccharides, oligosaccharide), polysaccharide, protein, amino acid, tannins and salvianolic acid B, etc. were analyzed. Results D101 macroporous resin was used for separation and purification of aqueous extract of Salviae Miltiorrhizae Radix et Rhizoma. The hygroscopicity of water elution parts was enhanced;carbohydrate, protein and other hydrophilic substances content increased; the content of salvianolic acid B was reduced to 1.76 mg/g. While the hygroscopicity and hydrophilic substances of alcohol elution parts were greatly reduced; the content of salvianolic acid B increased to 146.57 mg/g. Conclusion The hygroscopicity of aqueous extract of Salviae Miltiorrhizae Radix et Rhizomais closely related to the contained strong hydrophilic components, such as low molecular sugars, etc. Using D101 macroporous resin to purify aqueous extract of Salviae Miltiorrhizae Radix et Rhizoma can not only effectively gather the contain phenolic acids active ingredients, but also sharply decrease the extract yield and extract moisture absorption.

Objective To evaluate the occurrence and management of complications following ultrasound-guided minimally invasive percutaneous nephrolithotomy (MPCNL). MethodsFrom November 2003 to January 2011,2300 cases of ultrasound - guided MPCNL were performed for upper urinary tract stones in our department.Of these cases,renal calculi were found in 1305 cases,upper ureteral calculi in 322,renal and coexisting ureteral stones in 673. Results Among the 2300 cases of MPCNL,a total of 756 (32.9％) patients encountered complications.Of these cases,peel-away sheath placement failure occurred in 184 cases( 8.0％ ),in which six cases needed secondary surgery.Collecting system perforation occurred in 308 cases ( 13.4％ ),fever in 303 cases ( 13.2％ ),including septicemia in 20 cases (0.87％).The 20 septicemia patients received intensive antibiotic treatment and were successfully cured.Thrity-six patients required transfussions due to severe hemorrhaging ( 1.57％ ).Renal vein injury occurred in three cases (0.13％),for which these patients received intensive care therapy to provide haemostasis with a second procedure months later.There was extensive hemorrhage in 16 cases (0.70％) post-MPCNL,super-selective renal artery embolisation was performed in 12 cases and nephrectomy in 1 case.Pleural injury occurred in one case (0.04％) and pleural effusion in two cases (0.09％),all of which were cured with conservative therapy.There were no cases of abdominal organ injury.ConclusionsThe rate of ultrasound guided complications in MPCNL was lower than that of X-ray guided MPCNL in adjacent organ injury,but higher in complications related to the access ( such as:peel-away sheath placement failure,collecting system perforation),parenchymal bleeding and fever.Most complications (i.e.,bleeding,fever) could be managed conservatively or with minimally invasive procedures ( i.e.superselective renal embolisation,antibiotics treatment) when the complications were recognized early.Renal severe hemorrhage in operation,delayed hemorrhage and infection after MPCNL were several of the severe complications that required active prevention and cure measurement.

Objective To investigate the value of ultrasound in tethered cord syndrome (TCS) in infants. Methods From December 2005 to July 2013, 25 cases TCS were confirmed by surgery in Shenzhen children's hospital. The ultrasonogram and MRI of 25 infants were analysed retrospectively. The diagnostic accuracy of ultra-sound and its clinical significance were evaluated. Results In 25 cases of TCS confirmed by surgery, the coincidence rate of conus level detected by ultrasound [96%(23/24)] was lower than that by MRI (100%(25/25)). Ultrasound showed reduced spinal cord vibration in 4 cases, disappeared spinal cord vibration in 21 cases. Two cases of reduced spinal cord vibration detected by ultrasound were confirmed as disappeared spinal cord vibration by surgery. The coincidence rate of disappeared spinal cord vibration detected by ultrasound was 91%(21/23). The sacral spinal seg-ments form showed by ultrasound were entirely consistent with those of MRI, including 4 cases of enlarged spinal cord, 13 cases of spinal cord without enlargement and 8 cases of spinal cord ended with rat caudate. Twenty-five cases of TCS had malformations:7 cases meningocele (3 cases combined lipoma), 14 cases myelomeningocele (5 cases combined lipoma, 1 case combined hydromyelia), 3 cases spinal canal-epidermis fistula (all combined lipoma) and 1 case solitary lipoma. Compared with the operation findings, ultrasound misdiagnosed 2 cases of myelomeningo-cele as meningocele, missed 1 of case lipoma which combined with meningocele. MRI missed two cases of spinal canal-epidermis fistula. Conclusions Infantile spinal ultrasound examination can accurately locate the position of conus, accurately display the spinal cord. Compared with MRI, ultrasound examination can real-time visually display spinal cord vibration and help to diagnose tethered cord. Ultrasound examination are convenient, repeatable opera-tion with low cost, therefore it can be used as the preferred screening method to diagnose of tethered spinal cord.

Objective: To explore the correlation of plasma level N-terminal pro-B-type natriuretic peptide (NT-proBNP) in patients with non-diabetic acute myocardial infarction (AMI) combining stress hyperglycemia.
Methods: A total of 327 non-diabetic AMI patients treated in our hospital from 2012-02 to 2014-05 were studied. The patients were divided into 2 groups according to fasting blood glucose level:Stress group, the patients with blood glucose≥7.0 mmol/L, n=182 and Non-stress group, the patients with blood glucose<7.0 mmol/L, n=145. The basic clinical condition, laboratory tests within 24 hours of onsets, echocardiography and 24 h dynamic electrocardiogram were examined;the incidence of major adverse cardiovascular events (MACE) including arrhythmia, heart failure, cardiac shock and sudden cardiac death in 2 weeks of onsets were analyzed and compared between 2 groups.
Results: The patients’ age, gender, history of hypertension, smoking, drinking, and blood levels of TC, TG, HDL-C, LDL-C were similar between 2 groups, P>0.05. Plasma levels of NT-proBNP, CK-MB, MYO, ultra-TnI, ALT, AST and blood glucose level were signiifcantly different between 2 groups P<0.01. NT-proBNP level was positively related to
ultra-TnI (r2=0.811, r=0.901, P<0.01). Stress group presented obviously higher incidence of MACE (P<0.05), lower LVEF (P<0.01), and signiifcantly increased left ventricular end diastolic diameter, left ventricular end systolic diameter (P<0.01) than those in Non-stress group.
Conclusion: Plasma levels of NT-proBNP may judge the severity and evaluate recent prognosis in patients with non-diabetic AMI combining stress hyperglycemia, it could be used as a risk indicator for relevant patients in clinical practice.

Objective To investigate the efficacy and safety of ultra-mini percutaneous nephrolithotomy for the treatment of renal or upper ureteral stones.Methods The data of 32 patients diagnosed as renal or upper ureteral stones were retrospectively reviewed,who underwent ultra-mini percutaneous nephrolithotomy from June to October,2015,including 29 kidney stones,3 upper ureteral stones,of which 21 single stone,7 multiple stones,and 4 staghorn stones.There were 8 cases with inferior calyx stones,10 with renal pelvis stones,3 with upper ureteral stones,10 with renal pelvis stones plus inferior calyx stones and 1 with renal pelvis stones plus upper calyx stones.The mean stone size was (20.1 ±7.6) mm (ranging from 10 to 41mm).The mean Hounsfield unit (HU) was (1 125.9 ±225.9) Hu (ranging from 520 to 1 550Hu).In this cohort,13 cases had mild hydronephrosis,2 moderate hydronephrosis,1 severe hydronephrosis while no hydronephrosis identified in the other 16 patients.One case had concomitant kidney and ureter duplication malformation,and 1 case had residual stones after laparoscopic nephrolithotomy.Results All of the patients were treated by single tract UMP.Among them,middle calyceal puncture was performed in 9 cases,and the other 23 cases underwent lower calyceal puncture,including 4 cases of intercostal puncture,and 28 subcostal puncture.The mean operating time was (30.3 ± 15.0) min (ranging from 10 to 90 min).The mean postoperative hospital stay was (1.9 ± 1.0)days (ranging from 1 to 5 days).The mean hemoglobin decrease was(14.6 ±8.4)g/L (ranging from 1 to 46 g/L).No analgesics were used.Peri-operative complication rate was 3.13％ (1/32) with 1 case of collection system perforation.There was no fever,severe bleeding,urinary extravasation,pleural injury,or blood transfusion.The SFR was 93.75％ (30/32) and 96.88％ (31/32) on the first day and the first month after the operation,respectively.Conclusions UMP could be a safe and effective method for the treatment of renal or upper ureteral stones,especially for inferior calyceal stones less than 2cm.It offers high stone clearance rate,minimally invasiveness,quick recovery,short length of hospital stay and improved quality of life.

Objective To probe the relationship between the connectivity of premotor area detected by resting state functional MRI and stereotyped behavior of ASD.Methods 39 children patients with ASD and 42 healthy controls with matched age,sex and IQ were recruited.All the 81 subjects performed scaling with behavior scale index and underwent resting-state fMRI scans.After the fMRI data precession,the premotors in left and right sides were selected as ROI seeds to perform functional connectivity.Results Compared with healthy controls,children patients showed significant increased connectivity between the left premotor area and posterior cingulate cortex,as well as decreased functional connectivity between the left premotor area and the left insula.In addition, a negative linear correlation was showed between the connectivity of the left premotor and the insula and the behavioral scores.Con-clusion Imbalanced premotor functional connectivity may be one possible mechanism of stereotyped behavior of ASD,representing an attention deficit and/or impaired sensory perception to the external salient stimuli.
