OBJECTIVETo observe preliminary efficacy of decompressive unilateral improved transforaminal lumbar interbody fusion (TLIF) for the treatment of lumbar degenerative diseases.

METHODSFrom August 2009 to December 2011, 28 patients with lumbar degenerative diseases were treated by decompressive unilateral improved TLIF,including 16 males and 12 females with an average of 61 (aged 46 to 71) years old,the courses of disease ranged from 6 months to 6 years. Among them, 20 cases suffered from lumbar spinal stenosis, 8 cases were lumbar disc herniation. Decompressive range included single segment in 24 cases,and double segments in 4 cases; 15 cases were performed operation on the left side, 13 cases on the right side. JOA lower back pain scoring system (29 points) were applied for evaluate preoperative and postoperative symptoms, physical signs and sphincteral functions;Visual analogue scale (VAS) were used to evaluate preoperative and postoperative low back pain.

RESULTSAll patients were followed up 6 to 28 (mean 14) months. Postoperative JOA score and VAS score were 17.9 +/- 2.2, 2.8 +/- 0.7 respectively,and preoperative JOA score and VAS score were 8.5 +/- 1.7, 8.6 +/- 1.2, respectively. There were significant meaning in JOA and VAS scores before and after operation (P < 0.05). Twenty-eight patients were all obtained intervertebral synostosis.

CONCLUSIONDecompressive unilateral improved TLIF for treatment of unilateral radicular lumbar spinal stenosis and lumbar disc herniation,which has advantages of minimally invasive,curative effects,decrease medical costs,is worthy spreading in clinical.

Objective To study the effect of prolactin(PRL) on the activation of T lymphocytes stmiulated by concanavalin A(ConA),and to explore the action of PRL in the activation of T lymphocytes. Methods After CD4 +T cell line JurkatE6-1 cells were respectively stmiulated by 5 mg/L ConA,25 ?g/L PRL and 500 ?g/L bromocriptine(Brc).The blank control group,the ConA group,the PRL and ConA group(PRL group),the Brc and ConA group(Brc group),the PRL and Brc group(PRL-Brc group) were set in the experiment.The total RNA was extracted by Trizol after 48 hours and was reversed transcription immediately.The expression of tumor necrosis factor receptor associated factor 6(TRAF6) mRNA of T lymphocytes was checked by PCR.The expressions of tumor necrosis factor(ligand) super family 4(TNFSF4) and Killer specific secretory protein of 37 000(KSP37) mRNA of T lymphocytes were detected by real-time polymerase chain reaction. Results The PRL group and the Brc group could inhibit the expressions of TRAF6,TNFSF4,and KSP37 mRNA of the activated T lymphocyte compared with the blank control group and the ConA group(P a0.05).The PRL-Brc group could inhibit significantly the expressions of TRAF6,TNFSF4,and KSP37 mRNA of the activated T lymphocyte compared with the ConA group(P a

Objective To explore the effects of extract of Gingko biloba leaves (EGb) on learning, memory and hippoeampal heine oxygenase-1 (HO-1) expression in diabetic rats.Methods The behaviors of streptozotoein-induced diabetic rats were observed by Morris water maze for learning and memory after 6 months of diabetes.The HO-1 mRNA expression and protein expression in hippocampus of diabetic rats were detected by RT- PCR and immunohistochemistry respectively.Results The escape latency time in Morris water maze of diabetic rats was prolonged markedly.HO-1 mRNA and HO-1 protein expressions in hippocampus of diabetic rats were increased (1.635?0.326 vs 0.978?0.214,7.2?1.7 vs 1.9?0.5,respectively,both P＜0.01).The escape latency times in EGb (100,50 mg/kg) treated groups were shortened.HO-1 mRNA and HO-1 protein expressions in hippocampus were decreased at the same time as compared with diabetic group (100 mg/kg:0.954?0.144,2.0?0.8;50 mg/kg:0.988?0.154,2.5?0.6,all P＜0.01).Conclusion EGb can significantly inhibit HO-1 expression in hippocampus and improve learning and memory dysfunction in diabetic rats.

The traditional Chinese medicine of Radix Hedysari plays an important role in invigorating gas for as-cending, benefiting blood for promoting production of fluid, and promoting circulation for removing obstruction in collaterals, which is consistent with the principle of treatment for osteoporosis. This study is designed to investigate the bioactive components on increasing peak bone mass (PBM) by exploring the spectrum-effect relationship between chromatography fingerprints and effect. Multiple indicators are selected to evaluate the pharmacological activity. In fingerprints, 21 common peaks are obtained, five of which are identified. Furthermore, gray relational analysis (GRA) is a quantitative method of gray system theory and is used to describe the correlation degree of common peaks and pharmacological activities with relational value. 21 components are then divided into three different regions, of which ononin and calycosin play an extremely significant role in increasing PBM. In addition, factor analysis and hierarchical cluster analysis (HCA) are used to screen the optimal producing area for Radix Hedysari. This provides a comprehensive and efficient method to improve the quality evaluation of Radix Hedysari, confirming the bioactive components for PBM-enhancement and further develop its medicinal value.

Objective To analyze the results of the Objective Structured Clinical Examination(OSCE) of medical interns in Department of Gynecology and Obstetrics,and to assess the role of OSCE in clinical teaching and practice. MethodsAtolal of 104 medical interns of five-year education program in 2002 and seven-year education program in 2003 in School of Medicine had taken part in OSCE of gynecology and obstetrics.The OSCE consisted of six stations: gynecologic examination,obstetric examination,oral test,interrogation of standardized-patients(SP),drawing partogram,and non-stress test(NST) explanation.After gathering the data of each station,the software of SPSS 11.0 was used to make statistical analysis. Results The median scores were as follows: 92.0 for gynecologic examination,91.0 for obstetric examination,83.5 for oral test,80.0 for interrogation of SP,80.0 for drawing partogram,and 70.0 for NST explanation.There was no significant impact of familiarity to OSCE on the results of the test.The results showed that medical interns did good job in basic performance,but lack of clinical practice skills in some complicated practice of gynecology and obstetrics.Conclusion The grading system and stations setup of OSCE in Department of Gynecology and Obstetrics in Shanghai Sixth People's Hospital show objectivity and equity.The OSCE can be widely applied in the after-department examination and even graduation examination.

OBJECTIVETo investigate the placement of a long tube into the small intestine under fluoroscopic guidance and to evaluate its decompression effect on early postoperative small bowel obstruction (EPSBO).

METHODSFifty-four patients with EPSBO requiring decompression between April 2010 and July 2014 were enrolled in the study. Insertion of a long tube was guided by fluoroscopy. We first used the guide wire to pass the pylorus and then used the 10 Fr feeding tube as an exchangeable tube to put the superstiff wire into the duodenum. Finally the long tube could be passed over the guide wire through the pylorus into the intestine. The total procedure time, the radiation exposure time, and the incidence of complications were evaluated.

RESULTSThe long tubes passed into the jejunum on initial insertion for all patients, so the success rate of this technique was 100%. The long tube was inserted into ileum in 18 patients. The mean total procedure time was 34.4 ± 8.6 minutes, and the mean radiation exposure time 18.9 ± 6.8 minutes. A total of 47 patients (87%) experienced full recovery following long-tube decompression and without the need for surgical intervention.

CONCLUSIONSUsing the wire-exchange technique, it is easy to place a long tube into the small bowel under fluoroscopic guidance. This decompression method is safe and effective for management of EPSBO.
