Pancreatic cancer is a kind of high degree of malignant gastrointestinal tumor,and its incidence has increased significantly in recent years.Due to the low early diagnosis rate,and the extreme low middile or late resection rate of pancreatic cancer,Pancreatic cancer's prognosis is poor.Therefore,improving the early diagnostic rate of pancreatic cancer has very important significance for improving the prognosis.Early diagnosis of pancreatic cancer is dependent on tumor markers detection to a great extent.And proteomics progress rapidly in recent years and has been widely applied in clinical research.It provides an effective way to find markers.Among all of the spec imens,secrum is easy to obtain,and it allows repetitive detection.What is more,secmm is also renewable.So it is the most ideal for biological specimens.In this review,the proteomics technology role in pancreatic cancer patients serum detection were summarized.

Objective To investigate the consistent long-term clinical efficacy of the procedure for prolapsed hemorrhoids (PPH) treatment for hemorrhoids.Methods Data of 87 patients with third-and fourth-degree hemorrhoids treated by surgical procedure for prolapsed hemorrhoids were collected.In all cases,third-degree hemorrhoids in 65 cases,fourth-degree hemorrhoids in 22 cases,median followed up after PPH was (3.8 ± 0.5) years.The long-term efficacy and the occurrence of complications were followed up to assess the effect of surgical procedure for prolapsed hemorrhoids.Results In patients with third-degree hemorrhoids,bleeding recurred in 2 cases (3.1％) for again bleeding,for anal bulge in 4 cases (6.2％).In patients with fourth-degree hemorrhoids,prolapse recurred in 2 cases (9.1％) for bleeding in 5 cases (22.7％).anal bulge 3 patients (13.6％),defecation difficult in one case (4.5％),one-degree of fecal incontinence in 1 case (4.5％),no other complications found,such as anal pain,anal stenosis,foreign body discomfort and fecal urgency.The chi-square test for comparison analysis suggested that:third-degree hemorrhoids postoperative prolapse and bleeding recurrence rate was significantly lower than fourth-degree hemorrhoids.Conclusions Procedure for prolapsed hemorrhoids treatment for hemorrhoids is safe and feasible,has small trauma,little pain,and definite efficacy,fewer complications,shorter hospital stay,lower reoperation rate,etc.But the long-term efficacy for third-degree hemorrhoids is superior to the fourth-degree hemorrhoids.

Objective To analyze the results in neonatal hearing screening,and then to make diagnosis and intervention for neonates with hearing problems as soon as possible.Methods From January 2004 to December 2008,7 064 newborns at Shanghai East Hospital received hearing screening by distortion product oto-acoustic emissions (DPOAE) 2～4 days after birth.Re-screening tests were performed for infants who failed the initial screening 42 days after birth.Those newborns who failed again received further audiologic diagnostic evaluations 3 months afterwards.Results Among 7 064 cases screened,out of 6 412 normal newborns,579 (9.03%)failed the initial screening,and 38 (7.41%)failed re-screening.129 cases of the other 652 (19.79%) newborns in NICU failed the initial screening,and 20 cases (18.69%) failed re-screening.There were statistical differences between the passing rates of the two groups (P

Objective To discuss the effect of operations for comminuted patella fractures with cable cerclage and revised tension band. Method Retrospective study of clinical effects of 120 patella fractures cases which used cable(cable group,55 cases) or NT-PC (NT-PC group,65 cases) to internal fix.Results At 10 to 38 ( 19.50 ± 1.15 ) months follow-up, all cured well in 12 weeks. Compared with the operative time, the amount of blood loss, length of hospitalization, time for cure, the incidence of complications,there were no significant differences between two groups (P ＞ 0.05 ). The B (o)stman score of cable group [(27.0 ±0.2) scores] was better than that of NT-PC group [(25.1 ±0.6) scores](P＜0.05). Conclusion Using cable cerclage and revised tension band to internal fix for comminuted patella fractures,the operations are facile and the results are satisfactory.

Objective:To construct an adenovirus-mediated mouse endostatin vector (Ad-mEndo) and to observe its inhibitory effect on the pulmonary metastasis of osteosarcoma in nude mice, so as to discuss the relationship between ES expression and the pulmonary metastasis of osteosarcoma. Methods: Recombinant adenovirus plasmid pDC315-mEndo was constructed and used to prepare recombinant Ad-mEndo. Osteosarcoma MG-63 cells were subcutaneously injected into the right fore limbs to establish nude mouse model of osteosarcoma; and the models were randomly divided into 3 groups: Ad-mEndo group, Ad-EGFP group and PBS group; animals receiving no transplantation served as blank control. The corresponding agents were injected (20 ?l per time) for a consecutive of 5 times on a weekly basis. The tumor volumes, histopathological characteristics were observed; ELISA was employed to examine the serum ES level. Animals were sacrificed 7 weeks later and the pulmonary metastasis was observed. Results: Sixteen days later,the tumor volume was (1.53?0.05)cm3 in Ad-EGFP group, (1.56?0.07)cm3 in the PBS group, and (0.91?0.03)cm3 in the Ad-mEndo group, with the tumor inhibitory rate being 40.7% in the last group. The serum ES level in the Ad-mEndo group was significantly higher than that of the other groups (P

Objective To explore the effectiveness of 125I seed implantation for gastric cancer and to determine whether the therapy could increase the survival rate.Methods Seventy-six gastric cancer patients in stage Ⅱ or Ⅲ were involved and randomly divided into treatment group (n =42) and control group (n =34)by simple random sampling method.The patients in the control group underwent D2 or D3 surgery and the patients in treatment group underwent D2 or D3 surgery plus interstitial implantation of 125I seeds.All patients signed the informed consents.Treatment results were evaluated as CR,PR,NC and PD.CR and PR were considered as effective and the effective rate was calculated.All patients were followed up and the three-or five-year survival rate was calculated,the complications were examined.x2 test was used to compare the significant difference between the two groups.Results The total effective rate in control group was 50.00％ (17/34),lower than that of treatment group (73.81％,31/42; x2 =4.578,P＜0.05).In the treatment group,the three-year and five-year survival rates were 61.90％(26/42) and 42.86％(18/42) respectively,and the corresponding rates in the control group were 11.76％(4/34) and 0(0/34) respectively (x2=19.771,19.094,both P＜0.001).Both of the two groups had few severe side effects.Conclusion Radical surgery plus 1~Iseed implantation is effective and safe for the treatment of stage Ⅱ or Ⅲ gastric cancer and can further improvelong-term survival.

Background During the past two decades, a number of rating scales were developed to facilitate diagnosis and assessment of subjects with social anxiety disorder. One of the most commonly used scales for the assessment of social anxiety disorder is the Liebowitz social anxiety scale (LSAS). The LSAS is widely used in epidemiologic investigations and clinical researches,and its assessment in the pharmacotherapy efficacy for social anxiety disorder is superior to any other scale. So we designed this study to explore the validity and reliability of the LSAS in Chinese patients with social anxiety disorder and normal control, and to find the difference of the scores between the patients self -report version and clinician-administered version. Methods Fifty five patients meeting the DSM-Ⅳ diagnostic criteria for social anxiety disorder and 168 normal controls who were screened from 222 college students were rated by LSAS, social phobia scale and self-made General Information Forms. Results The Cronbath α of LSAS for the patients and the normal controls was 0.83 and 0.77, respectively. The 4-week test-retest reliability for total scores and its factors scores of LSAS in 31 normal controls were ranging from 0.68 to 0.79. The ROC area under curve value in discriminating the patients from normal controls was 0.87±0.03; the total score of 35 was considered to be the best cut-off score for LSAS, then its sensitivity was 0.77 and its specificity was 0.81; and no significant difference between the self-report version and clinician-administered version. Conclusions The LSAS is good in internal consistency and test-retest reliability, and has high sensitivity and specificity in discriminating the patients and the controls. There is no significant difference in the total score and each factor scores of LSAS between self-report version and clinician-administered version.

Objective To evaluate the clinical efficacy and safety of piperacillin and sulbactam sodium combinations in the treatment of common infections. Methods This was a multi-centre, prospective and open study. All subjects from 57 wards caught common infection like respiratory ( RTI) or urinary diseases ( UTI). The dosages of piperacillin and sulbactam sodium combinations 2. 5 g injection were determined according to indications:for adult, 2. 5 g or 5 g per time, 2 time/day; for severe or obstinate infection, 2.5 g or 5 g per time, 3 time/day. General information, clinical response pre- and posttreatment, infected locus, drug recipe and protocol, prognosis and adverse reaction were recorded. Results Data of 579 cases were collected with 388 males and 191 females. The average age was (66. 8 ± 17. 0) years. There were 500 patients who were suffering with RTI, with 362 cases of pneumonia, 102 of acute exacerbation of chronic bronchitis, and 36 of other infections. There were 50 cases with UTI, with 31 of simple urinary tract infection, and 19 of complex urinary tract infection. In addition, there were 9 cases of combined RTI and UTI, and 20 of other infections including peritonitis. The average duration of antimicrobial for RTI and UTI was (8. 65 ± 3. 78 ) days and (7. 45 ± 3. 46) days respectively with the total efficacy rate was 92. 6% and 98. 0% respectively for RTI and UTI. The incidence of adverse events was only 0.86% (5 cases), including nausea, rash, itching, ALT elevation and suspected drug induced fever in each one. Conclusion Piperacillin and sulbactam sodium compound had high clinical efficacy and safety in the treatment of common infections including RTI and UTI.

Objective To investigate the relationship between HLA-B * 5801 allele and severe cutaneous adverse reactions caused by allopurinol or other drugs.The clinical value of HLA-B * 5801 as the marker of allopurinol-SCAR was evaluated.Methods Forty-three patients with allopurinol-SCAR,133 patients without SCAR after taking allopurinol for 3 months were included.Ninety-six patients with SCAR caused by other drugs and 148 healthy individuals were enrolled into the present study.HLA-B * 5801 allele was detected by PCR-SSP method.Data were analyzed by chi-square test.Results HLA-B * 5801 was present in 40 of 43 (93.0％) patients with allopurinol-SCAR,which was significantly higher than 19 of 148 (12.8％) in healthy subjects (x2=100.353,P＜0.01,OR=90.5,95％CI 25.5-321.8).But there were no significant differences between allopurinol-tolerant patients and healthy controls(10 of 133,7.5,x2=2.141,P＞0.05,OR=0.6,95％CI 0.2-1.2).And there were only 14 of 96 (7.5％) patients with SCAR caused by other drugs had HLA-B * 5801 (x2=0.152,P＞0.05,OR=1.2,95％CI 0.6-2.4).Conclusion The study indicates that people with HLA-B * 5801 have a high risk of allopurinol-SCAR.HLA-B * 5801 is a specific and predictive marker for guiding the selection of uric acid lowing drug allopurinol.
