BACKGROUND: With development of modern medical sciences, the out comes after meningioma surgery cannot be fully assessed using morbidity,livability and mortality merely. Quality of life (QOL) is a health-related multivariable index, which provides integrated inf ormation associated with physiological,sychological and social adaptation status of the patients to doctors. Assessment of the QOL in meningioma patients may be one of a relatively good method for guiding surgery and reducing reoccurrence of tuOBJECTIVE: To evaluate the QOL in meningioma patients and then to provide relevant data for assessing the outcomes of meningioma surgery comprehensively.DESIGN: It was a single-sample investigation. SETTING: Neurosurgery Department, Second People's Hospital of Wuxi City of Nanjing Medical University.PARTICIPANTS: Totally 147 patients underwent meningioma surgery in the Neurosurgery Department of the Second Affiliated Hospital of Wuxi City affiliated to Nanjing Medical University between January 1995 to January 2001 were selected, 61 males and 86 females, with a male/female ratio of 2:3 and an age ranging from 5-77 years old, in average of 43 years old, and the median was 43 years old.METHODS: Based on World Health Organization Quality of Life 100item questionnaire (WHOQOL-100) and Karnofsky Performance Scale (KPS), we designed a questionnaire on QOL in patients with meningioma.Outcomes of the transverse investigation on 147 meningioma patients were compared with healthy controls. Surgery-related QOL curve was used for identifying the threshold satisfactory point of QOL. In addition, with selfcontrol, influence of surgery on QOL was assessed.MAIN OUTCOME MEASURES: Relationship between QOL and clinical histories, radiological analysis, operation grading, histological properties and reoccurrence were investigated.RESULTS: All of the 147 patients entered the statistical analysis. ①In patient with meningioma, Cronbach's coefficient was 0.9521 and the correlated coefficient was 0.8685, which suggested that QOL questionnaire for patients with meningioma had a good reliability and validity. ②QOL ≥70 represented that the patient was satisfied with the QOL. ③In patients underwent surgical treatment, their physiological functions, self-help and self-care except for psychological functions were significantly improved (P ＜ 0.001 ).CONCLUSION: Surgical treatment enables patients to get a satisfied QOL. QOL questionnaire for patients with meningioma is helpful to provide relevant data for meningioma operation.

BACKGROUND:Intraarticular cocktail analgesic injection is a popular postoperative analgesia method and can effectively control postoperative pain and relieve side effects after total hip arthroplasty.
OBJECTIVE:To compare and assess the effectiveness and safety of intraarticular analgesic injection or intravenous injection of parecoxib after total hip arthroplasty.
METHODS:A total of 60 patients undergoing total hip arthroplasty were randomly assigned to:treatment group (intraarticular cocktail analgesic injection with morphine, bupivacaine, and compound betamethasone), and control group (intravenous injection of parecoxib). Al patients received tramadol hydrochloride at 24 hours after replacement. Analgesic consumption, visual analog scale at rest and during activity, range of motion, and postoperative complication of patients in each group were recorded.
RESULTS AND CONCLUSION:Intraarticular cocktail analgesic injection significantly reduced analgesic consumption. When comparing visual analog scale scores, rest pain scores were significantly less in the treatment group at 12, 24 and 48 hours after replacement than that in the control group (P<0.05). Scores on range of motion were significantly less in the treatment group at 24 and 36 hours than that in the control group (P<0.05). No significant differences in total complications were detectable between the treatment and control groups (P>0.05). Results suggested that intraarticular cocktail analgesic injection lessened analgesic consumption after replacement, relieved early pain after replacement, and contributed to early rehabilitation of patients. Moreover, no significant adverse reactions were visible.

Objective To investigate the clinical characteristics, operation time and methods for patients with central brain herniation caused by bifrontal contusions. Methods A retrospective study was performed on the medical records of patients with central brain herniation caused by bifrontal contusions admitted from January 2000 to December 2006. There were 45 males and 18 females, at age range of 20-72 years (average 43 years). The majority of the patients were victims of falls and traffic accidents. There were 29 patients treated with immediate operation and 34 with emergency operation. All the operations involved simultaneous bilateral craniectomy for decompression, including 17 patients treated with bilateral decompressive craniectomy and 46 with unilateral decompressive craniectomy. Results The prognosis was favorable in 19 patients with GOS score of 5 or 4 points, severely disabled in seven with GOS score of 3 points, vegetative in four with GOS score of 4 points and the worst in seven with GOS score of 1 point. Of all, 19 patients suffered severe mental disorders especially personality change and disturbance of intelligence. Seven patients were complicated by epilepsy and three by hydrocephalus. Conclusions Based on early clinical manifestations of central brain herniation combined with imaging manifestations, bilateral balance decompression craniectomy can reduce the mortality and morbidity and improve the cure rate of patients with central herniation caused by bifrontal brain contusions.

Objective To evaluate the Flavivirus specific monoclonal antibody(McAb) 2A10 as detective antibody for simultaneously identify tick borne encephalitis virus( TBEV), Japanese encephalitis virus( JEV), dengue ( DEN )-2, DEN-4 and yellow fever virus ( YFV ) by antibody microarray technique.Methods The antibody microarray was developed by spotting TBEV, JEV, DEN-2, DEN-4 and YFV specific McAb on chip as capture antibodies. After incubating with cultured viral supernatants of the above viruses, CY3 labeled detective antibody 2A10 was added to the chips. After reaction, the antibody microarray was scanned and the results were analyzed.

Purpose:To evaluate the role of multi - detector row CT(MDCT) using reconstruction techniques in the assessment of patients with obstructed diseases of biliary tract.Materials and Methods: 47 Patients with obstructed diseases of biliary tract confirmed clinically underwent MDCT and their reconstructed images of biliary tract including multi-planar reconstruction (MPR) images and curved planar reconstruction(CPR) images were compared with those of 50 patients without obstruction and dilatation of biliary tract.The display effect of biliary duct structure and biliary duct wall and the display ability of biliary tract by MPR and CPR images between the 2 groups were compared and analysed.The reconstruction images of biliary tract were analysed retrospectively to evaluate the location and possible causes of biliary obstruction.Results: The display effect of biliary duct structure and biliary duct wall in MPR and CPR images of the group with biliary obstruction is better than that of control group,and the display ability of biliary tract in CPR images of the group with biliary obstruction is also better than that of control group.The accuracy of localization and cause evaluation of obstruction by MPR and CPR images is 100% and 89.4% respectively.Conclusions: The MPR and CPR images of MDCT provide a good display of biliary duct structure,biliary duct wall and an accurate evaluation of obstruction localization.The reconstruction technique of MDCT such as MPR and CPR should be widely applied in the evaluation of biliary obstruction.

Objective To compare the consistency between the estimated values of nine common resting energy expenditure estimation equations and the measured values among the elderly population in pension institutions. Methods A total of 181 elderly individuals from Henan Guangda Ouan Leling Nursing Center were recruited as study objects through cluster sampling. The differences between the estimated values of nine common equations and the measured values obtained by indirect calorimetry were compared, and subgroup analyses were conducted to compare their consistency across different subgroups. Results Among the nine equations, the Cunningham equation and the Owen equation showed relatively small deviations from the measured values, with no significant differences (deviation rates of -1.9% and -2.0%, root mean square errors of 222.7 kcal/d and 239.4 kcal/d, and coincidence rates of 48.4% and 47.5%, respectively). In subgroups stratified by gender and body mass index (BMI), the Cunningham equation showed no significant difference compared with the measured values. The Owen equation showed no significant difference compared with the measured values only in some subgroups [males with BMI of 20~ < 27 kg/m² and ≥27 kg/m², and females with BMI < 20 kg/m²]. Conclusion The Cunningham equation, which utilizes body composition data, can assess the resting energy expenditure of the elderly in pension institutions with relatively high accuracy and speed, demonstrating strong applicability in this population.

Objective To explore the efficacy of superior hypogastric nerve block(SHNB)for alleviating pain after uterine artery embolization(UAE).Methods Twenty-five patients with hysteromyoma who underwent UAE were retrospectively enrolled.The patients were divided into SHNB group(n=11)and non-SHNB group(n=14,receiving peripheral intravenous analgesia)according to analgesia methods.The technique success rate and complication of SHNB were recorded.The maximum score of numeric pain-rating scale(NRS),the total dose of opioid consumption after UAE and the interval time between UAE completed to the first additional use of opioid were compared between groups.Results No significant difference of patient's age,body mass nor the maximum diameter of hysteromyoma was found between groups(all P＞0.05).The technique success rate of SHNB was 100%(11/11).No complication such as lower limb radiating numbness,intravascular injection,intraperitoneal hemorrhage nor peritonitis occurred.The maximum score of NRS after UAE and the total dose of opioid consumption after UAE in SHNB group were both significantly lower,while the interval time between UAE completed to the first additional use of opioid in SHNB group was significantly longer than those in non-SHNB group(all P＜0.001).Conclusion SHNB was effective for alleviating pain and reducing required dosage of analgesic medications after UAE in patients with hysteromyoma.

Objective To identify stable reference genes for a comparison of the transcription levels of target host genes under viral infection in order to provide data for studies on interactions between the host and the influenza virus.Methods Reverse transcription quantitative real-time PCR(RT-qPCR)was performed to detect the relative expression levels of six candidate reference genes,including glyceraldehyde 3-phosphate dehydrogenase(GAPDH),β-actin,18S RNA,β2-microglobulin(B2M),ubiquitin-conjugating enzyme E2D2(UBE2D2),and ribosomal protein L37A(RPL37A)in classical cell models(A549 cells and THP-1 cells)under different conditions.The stability of the reference genes was evaluated using such methods as BestKeeper,GeNorm,NormFinder,and comparative A Ct method.Results The stability of reference genes varied depending on conditions.When such experimental factors as influenza virus infection and immune activation were taken into consideration,β-actin and GAPDH were identified as the most stable reference genes in A549 cells and THP-1 cells,followed by UBE2D2 and B2M.Conclusion The optimal reference genes in A549 cells and THP-1 cells under influenza virus infection or after being treated with interferons or LPS have been identified,which is of referential value for studying the mechanisms of viral infections.
