Objective To investigate effects of parecoxib sodium preemptive analgesia on postoperative analgesia and cellu‐lar immune function in patients with uterine fibroids.Methods Totally ,116 cases of patients receiving uterine fibroids surgery were selected from March 2011 to April 2014 in our hospital.All cases were randomly divided into advanced group(n=58)and control group(n=58). The cases in the advanced group were intravenously injected with parecoxib sodium(40 mg)30 min before anesthesia ,while the control group received 5 mL saline intravenously.Postoperative pain conditions of the two groups were e‐valuated by using visual analog scale(VAS method). The PCIA pump first trigger time ,effective compression number and the total amount of fentanyl were recorded. Venous blood was collected before operation ,6 h(T1 ) ,24 h(T2 ) ,48 h(T3 )and 72 h(T4 ) after operation ,respectively. T lymphocyte subsets of CD3+ ,CD4+ and CD8+ and NK cells were detected by using FACS Cali‐bur flow cytometer.The ratio of CD4+ /CD8+ was calculated.Results After 4 ,8 ,12 ,24 and 48 h ,the pain scores of patients were significantly lower in the advanced group than in the control group(all P<0.05). The PCIA pump first trigger time was longer ,effective compression number and the total amount of fentanyl of patients were less in the advanced group than in the control group ,the differences were statistically significant(all P<0.05). At T1 ,T2 and T3 ,CD3+ and CD4+ were significantly higher in the advanced group than in the control group(P<0.05).At T1 and T2 ,CD4+ /CD8+ was significantly higher in the advanced group than in the control group(both P<0.05).At T2 and T3 ,the NK was significantly higher in the advanced group than in the control group(both P<0.05).Conclusion Parecoxib sodium preemptive analgesia used in patients with uterine fi‐broids can reduce postoperative pain ,reduce the amount of analgesics ,reduce the immune suppression ,and improve immune function in patients after surgery.

This paper uses AVR16 SCM, programming to achieve the software of PWM (pulse width modulation) control of intelligent H bridge chip LMD18200 driver of high speed DC motor, makes special speed tablet, obtains speed signal of high speed for photocoupler PC817, through the A/D conversion and processing circuit, and realizes the LED LCD digital display speed scheme. The driver for the pediatric ventricular assist device has been used at the laboratory trial, has high performance and wide application prospect.

Objective To evaluate the role of curved-cutter-stapler in anus-preserving for low rectal cancer.Methods The clinical data of 32 patients with low rectal cancer from June 2007 to December 2008 who received low anterior resection and ultra low anterior resection by using curved-cutter-stapler were reviewed retrospectively.Results No operation death case,complete cutting and safe closure in all cases,one case was complicated with anastomotic leakage,and one case of rectovaginal fistula.Thirty patients were followed up 4 to 22 months after the operation,with an average time of 12.6 months,no hemorrhea of pelvic cavity and anastomotic stoma or anastomotic stenosis cases.Conclusion Curved-cutter-stapler has the advantages of complete cutting,safe closure and low complications,and easy being used in anus-preserving operation for low rectal cancer,which can increase the rate of anus-preserving.

Objective To explore the clinical characteristics of neonatal dengue fever. Methods The clinical data from 4 neonates with dengue fever who were admitted and treated in 2014 were retrospectively analyzed and the related literatures had been reviewed. Results Four cases of neonatal dengue fever were all males. Three cases were mother to child transmission, the age at onset was 1 to 7 days after birth, and their mothers suffered with prenatal fever and were diagnozed of dengue fever during perinatal period. One case was community acquired, the age at onset was day 21 after birth and the neonate was bit by mosquito the day before. All four neonates had fever, two cases had rash, and one case had hemorrhagic spot. None of them had jaundice or cough. All of them had thrombocytopenia ( 30-125 )× 109/L, prolonged activated partial thromboplastin time ( 44 . 0-89 . 8 s), and increased aspartate aminotransferase (AST) ( 46-71 U/L). Three cases had declined ifbrinogen ( 1 . 36-2 . 53 g/L). Two cases had increased CK-MB ( 29-86 U/L). Two cases had increased CRP ( 3 . 00-46 . 05 mg/L). After the treatment of anti-infection and intravenous immunoglobulin, all of them were cured and discharged. The duration of hospital stay was 4-17 days. Conclusion The clinical manifestations of neonatal dengue fever were mainly fever and blood coagulation dysfunction, clinical symptoms are mild and lack of speciifcity, and prognosis are good. Mother to child transmission is one of the ways of dengue virus infection.

Cancer stem cells(CSCs)are a small subgroup of cells capable of initiating cancer and are associated with chemotherapy resistance and cancer recurrence.Cervical cancer is one of the major malignant tumors threatening women's health worldwide.With the popularization of cervical cancer screening,some early cervical cancer and precancerous lesions have been discovered and timely treated,but the treatment and prognosis of mid-to late-stage cervical cancer have not been markedly improved.The treatments of mid-to late-stage cervical cancer are still surgery,radiotherapy and chemotherapy.There-fore,effective targeting strategies for cervical cancer CSCs are increasingly important for monitoring the progress of cervical cancer treatment and evaluating new treatment methods.This article provides a brief review of the role of biomarkers of cervical cancer CSCs in the progression of cervical cancer and their potential as therapeutic targets.

Primary central nervous system lymphoma (PCNSL) is a rare and special kind of non-Hodgkin lymphoma. Chemotherapy based on high-dose methotrexate (HD-MTX) is considered a standard therapy for newly diagnosed PCNSL, but the prognosis of PCNSL is poor due to its high invasiveness and recurrence rate. Risk stratification and prognosis assessment of PCNSL in diagnosis is particularly important in clinical treatment. At present, MSKCC (the Memorial Sloan Kettering Cancer Center), the International Extranodal Lymphoma Study Group (IELSG) and Nottingham/Barcelona scoring models are mostly used to classify the risk and evaluate the prognosis of PCNSL. With the further understanding of immunohistochemistry and molecular genetics of PCNSL, potential prognostic factors continue to emerge.
