Objective To analyze the efficacy of umbilical one trocar laparoscopic appendectomy (UOTLA) in treatment of complicated appendicitis in children. Methods Clinical data of 78 cases of children patients with complicated appendicitis from January 2012 to October 2015 was summarized, including 44 cases as UOTLA group received umbilical one trocar laparoscopic appendectomy, 34 cases as OA group received open appendectomy. Then statistically analyzed all the patients' operation time, postoperative hospital stay, postoperative abdominal abscess, incision infection, early inflammatory intestinal obstruction and pain level. Results The laboratory test results of C reaction protein (CRP) had no significant difference between the two groups, while peripheral white blood cell count decreased more significantly in UOTLA group than that in OA group; the operation time of UOTLA group was shorter than that in OA group with no statistical difference [(66.59 ± 33.24) vs (72.86 ± 30.36) min, P > 0.05], but postoperative hospital stay was shorter [(8.21 ± 1.67) vs (9.21 ± 2.01) d, P < 0.05]. Abdominal abscess after operation: 3 cases in UOTLA group, while 1 case in OA group (P > 0.05); incision infection: 6 cases in UOTLA group, 9 cases in OA group (P > 0.05); early inflammatory intestinal obstruction: 1 cases in UOTLA group, 5 cases in OA group (P > 0.05); the pain level, postoperative recovery time was significantly shorter in UOTLA group compared with OA group (P < 0.05). The average expenses comparison of the two groups has no statistical difference [(10639.37 ± 2970.92) vs (10765.04 ± 2902.64) yuan, P > 0.05]. Conclusion UOTLA is safe and effective for complicated appendicitis in children due to minimally invasive, less pain and faster recovery without significant increase in the cost and postoperative complications. It can be applied in children with purulent, perforated appendicitis and gangrene, perforated appendicitis and other complicated appendicitis.

Objective To establish the evidence-based nursing educational programme for preventing ventilator-associated pneumonia (VAP) and evaluate the effects in critical care nurses. Methods The evidence-based nursing practice guidelines for preventing VAP from 2008 American Association of Critical Care Nurses was used as training materials,which guided the curriculum design. Seventeen critical care nurses were trained. The difference of the nurses' knowledge and practice was evaluated before and after training by an evaluation scale of nursing quality criteria for preventing VAP. Results After the training,nurses' knowledge and practice of preventing VAP were improved(Z=-3.624,P=0.000). Except the factor score of handwashing,there were significant differences on the factor scores of body position care,endotracheal tube care,enteral nutrition,maintaining the tube cuff pressure,oral care and ventilator equipment management (P<0.01). Conclusion The educational programme of evidence-based nursing for preventing VAP can improve the nurses' knowledge and practice of preventing VAP. Furthermore,it can promote the application of evidence-based nursing for preventing VAP,and thereby to improve the quality of nursing,and provide guidance for the training of critical care nurses and continuing education.

The clinical data of 42 patients with pelvic organ prolapse, who underwent laparoscopic sacral colpopexy using prolene meshes were retrospectively reviewed. During the operation prolene meshes were placed in the rectovaginal septum and vesicovaginal septum ,and the uterus was preserved in all cases.The mean operation time was (92 ± 12)min and the mean blood loss during the operation was (98 ± 11 )ml.Postoperatively, both prolapse and symptoms were significantly improved ( P ＜0. 01 ) according to the pelvic organ prolapse quantification (POP-Q) system. The operation is an effective and minimally invasive new technique which offers a chance for patients with pelvic organ prolaps who desire to preserve uterus.

Objectives : The objective of this study is to develop a Japanese version of the Constitution in Chinese Medicine Questionnaire (CCMQ) in Chinese, which is comprised of 60 items with 9 sub-scales, and evaluate its reliability and validity. Methods : We conducted a survey of 130 participants in the Toyama area of Japan from Dec. 2005, to Feb. 2006. A test-retest method was used. Feasibility was evaluated by the response times to the questionnaire, and the response rates of the CCMQ items. Internal consistency within the sub-scales was assessed by Cronbach's α coefficient. Reproducibility was confirmed between the first and second occasions using weighted kappa and Spearman correlation. Lastly, criterion validity was evaluated by correlation between CCMQ and SF-36 sub-scales. Results : Response time was 8 minutes on average and its rate was nearly 100%. Internal consistency was achieved for each of the 9 sub-scales with a 0.65 to 0.79 α coefficient. Reproducibility ranged from 0.41 to 0.81 for the items, and from 0.79 to 0.88 for the sub-scales. Regarding the criterion validity, the “Gentleness type” sub-scale was positively correlated with SF-36 (0.46, P<0.001), while other 8 pathological constitutional types of the CCMQ were negatively correlated with SF-36 (-0.35 to -0.50, P<0.001) as expected. Conclusions : We developed a Japanese version of the CCMQ and found acceptable levels of reliability and validity using a survey of 130 subjects in Japan. This suggests that the CCMQ could be a useful tool in comparing the constitution profiles between Chinese and Japanese.

It has been suggested that progression of bladder transitional cell cancer (BTCC) may be regulated at the molecular level by a typical pattern of expression of genes involved in apoptosis. Recently Livin, belonging to the inhibitors of apoptosis (IAP) family, has been found to be expressed in most solid tumors, where its expression is suggested to have clinical significance. In order to explore the significance of Livin expression in the development of BTCC, immunohistochemistry and RT-QPCR were used to detect the expression of Livin mRNA in tumor tissues and adjacent normal tissues of 30 cases of BTCC. The results showed that the positive rate of Livin expression in adjacent normal tissues and tumor tissues was 0 and 60% (18/30) respectively. The-DeltaDeltaCT value of Livin in BTCC tissues was 8.0454 (7.4264-8.6644) times of that in adjacent normal tissues. The expression of Livin mRNA had no correlation with tumor pathological grades and clinical stages. It was suggested that there was weak expression of Livin mRNA in adjacent normal tissues, but strong in tumor tissues.

Objective To investigate infection status and antimicrobial resistance mechanism of methicillin-resistant Staphylococcusaureus(MRSA),and provide reference for the rational antimicrobial use in clinic. Methods Staphylococcusaureus (SA)isolated from various specimens in Xuzhou area in 2012-2015 were collected,MR-SA strains were preliminarily screened by cefoxitin disk diffusion method,and confirmed by amplification of mecA gene,antimicrobial resistance of MRSA was determined by Kirby-Bauer method,minimal inhibitory concentration (MIC)was measured by E-test method,genotypes of staphylococcal chromosomal cassette mec(SCCmec)were de-termined by multiplex PCR. Results A total of 116 strains of MRSA were identified among 210 SA strains in 2012-2015,114 of which were positive for mecA gene,the total detection rate of MRSA was 55.24% . Susceptibility rates of MRSA to vancomycin,quinupristin/dalfopristin,and linezolid were all 100% ,resistance rates of MRSA to chloramphenicol and furantoin were both low,which were 15.52% and 1.72% respectively,resistance rates of MR-SA to 10 kinds of antimicrobial agents were all>80% ;resistance rates of MRSA to penicillins,aminoglycosides, macrolides,quinolones,sulfanilamide,rifampicin,tetracycline,and clindamycin were all higher than methicillin-sensitive Staphylococcusaureus(MSSA). MICs of vancomycin to MRSA in 2012-2015 were all 1.0μg/mL,MIC90 were all 1.5μg/mL,one MRSA isolate was with a vancomycin MIC of 2.0μg/mL in 2015. MRSA typing results of 116 MRSA isolates showed that SCCmec II,SCCmec III,and SCCmec IV accounted for 9.48% (n= 11),73.28% (n= 85),and 1.72% (Iva,n= 2;IVb,n= 2)respectively,13.79% (n= 16)of MRSA isolates were nontypeable, SCCmec I and SCCmec V type strains were not found. Conclusion MRSA is seriously multidrug-resistant,the drift has not been discovered in MIC value of vancomycin against MRSA,the major SCCmec genotype of MRSA is SCCmec III,infection control measures should be taken to control MRSA infection.

BACKGROUND: Osteoporosis is one of the complications of spinal cord injury, but its mechanism is unclear, different scholars have different points about whether all bones above and below the level of trauma are affected after spinal cord injury (SCI).OBJECTIVE: To observe the ultrastructure of bone tissue of secondary osteoporosis after spinal cord injury and the change of serum biochemical indexes, to analyze the suffered condition and injured degree of the bones above and below the level of the trauma.DESIGN: Randomized controlled experimentSETTING: Laboratory of Animals, and Department of Laboratory Medicine of the Second Clinical Hospital of Jilin University; Transmission Electron Microscope Center, Norman Bethune Division of Medical Sciences of Jilin UniversityMATERIALS: This experiment was conducted at the Laboratory of Animals, Second Clinical Hospital of Jilin University from May 2002 to May 2003. Totally 110 male Wistar rats, aged 4 to 5 month-old, with the body mass of (300 -320)g were involved.METHODS: Ten rats were randomly chosen from 110 male Wistar rats and were set as 0 week blank control group, the ther rats were randomly divided into experimental group and control group, there were 10 rats in week 1, 2, 3, 7 and 11 control group and experimental group separately.1 mL/L of pentobarbital natrium was intraperitoneal injected to perform anesthesia, in the control group, lamina with dura intact of rats were removed only, without spinal cord injury at the level of tenth thoracic vertebrae. In the experimental group, lamina of rats was also removed, the spinal cord injury model of the rats were made by the method of Allen's.4 mL venous blood was collected from the animals at the end of postoperative week 0, week 1, week 2, week 3, week 7 and week 11, then the animals were put to death, perform blood centrifuging .We observe the change of serum concentration of calcium, phosphorus and alkaline phophatase (ALP) with 7170A HITACHI auto-biochemistry analyzer. Right side humerus, tibia in week 0 blank control group, week 7 experimental group and week 11 experimental group were chosen, then 25 mL/L ethylene dinitrilotetraacetic acid was used for decalcium for 1 month for preparingthe sections. We observe the change of ultrastructure of osteocytes at the sites of tibial plateau and the surgical neck of the humerus after stained by uranyl acetate and lead citrate under transmission electron microscope.biochemistry detection: the level of phosphorus at week 2 of the experiment was significantly lower in the control group than experiment group [(1.54±0.21),(2.76±0.16)mmol/L, (P ＜ 0.01)]; the level of calcium at week 3 in the experiment group was significantly higher than in the control group [(2.52±0.06),(2.35±0.12)mmol/L, (P ＜ 0.01)];the level of alkaline phophatase at week 7 in the experiment group was significantly higher than in the control group [(155.86±20.42), (129.25±7.30)Nμ/mg,operative week 7, the tibia sample showed that the osteocyte separated from the osseous lacuna, the nucleus showed anomaly, fluffed materials appeared. Mitochondrion swelled, rough endoplasmic hollowed; At week 11, osteocyte separated from the osseous lacuna. At postoperative 7 week,the humerus sample showed that osteocyte separated from osseous lacuna,some nucleus pycnosis and rough endoplasmic hollowed; At postoperative week 11, the above changes still were seen, but the degree of cellular swelling and hollowing were lighten.CONCLUSION: At the early stage of spinal cord injury, the activity of osteoclast is increased and the activity of osteoblast is decreased, which leads to the increase of bone absorption, the bone formation is largely weakened. The bones above and below the level of trauma are both affected after spinal cord injury, but different extents of osteoporosis can be seen in different bones .The change of ultrastructure of osteocytes is remarkable when osteoporosis has happened.
