Secondary pancreatic infection in severe a-cute pancreatitis (SAP) was associated with mortality and the length of stay in hospital.Intensive Care Unit (ICU) identificate shock on account of the oxygen metaboilic level in earlier period of SAP and perform adequate fluid resuscita-tion.it advocate to perform organ function support and/or substitution therapy in time and think highly of coordination and combination each other among various kinds therapeutic measure.These therapeutic concept and measure will con-duce to decrease the incidence rate of MODS and secondary pancreatic infection accordingly in SAP.

Objective To evaluate the role of oxidative stress in the spinal neurotoxicity induced by ropivacaine in rats.Methods Ninety pathogen-free male Sprague-Dawley rats,weighing 250-320 g,aged 3 months,in which intrathecal catheter was successfully implanted into L5,6 interspace without complications,were randomly divided into 3 groups (n =30 each) using a random number table:control group (group C),ropivacaine group (group R),and antioxidant Tempol group (group T).The rats received 1％ ropivacaine 1.2 μg/g for 8 times at 1.5 h intervals through the catheter in R and T groups,while the rats received the equal volume of normal saline instead in group C.In T group,Tempol 20 μg/g was injected intrathecally at 4,8,12,24,48 and 72 h after the last injection of ropivacaine.The rats were sacrificed at 1,3,5,7 and 14 days after the end of ropivacaine injection,and their lumbar enlargements were removed for TUNEL staining to detect the cell apoptosis.SOD activity was determined by colorimetry and MDA content was measured using TBA photoelectric colorimetry.Apoptosis index was calculated.Results Compared with group C,apoptosis index and MDA content were significantly increased,and SOD activity was decreased in R and T groups.Compared with group R,apoptosis index and MDA content were significantly decreased,and SOD activity was increased in group T.Conclusion Oxidative stress is involved in the development of spinal neurotoxicity induced by ropivacaine in rats.

Objective To investigate the clinical efficacy of Xi-Cleft point acupuncture plus surrounding electro- acupuncture in treating occipital neuralgia.Methods Forty-eight patients with occipital neuralgia were randomly allocated to treatment and control groups, 24 cases each. The treatment group received Xi-Cleft point acupuncture plus surrounding electroacupuncture and the control group, surrounding electroacupuncture alone. The VAS score was recorded in the two groups before and after treatment. The clinical therapeutic effects were compared between the two groups.Results There was a statistically significant pre-/post-treatment difference in the VAS score in the two groups (P<0.05). There was a statistically significant post-treatment difference in the VAS score between the treatment and control groups (P<0.05). The total efficacy rate was 95.8% in the treatment group and 83.3% in the control group; there was a statistically significant difference between the two groups (P<0.05).Conclusion Xi-Cleft point acupuncture plus surrounding electroacupuncture is an effective way to treat occipital neuralgia.

PURPOSE To investigate the effects of bcr3/abl2 anisense oligodeoxynucleotide (ASO) on chronic myeloid leukemia (CML). METHODS The effects of bcr3/abl2 ASO in 15 CML patients were evaluated by morphological observation, flow cytometer (FCM) techniques and DNA fragment measurement. RESULTS bcr3/abl2 ASO can induce apoptosis in CML. CONCLUSION Antisense techniques may provide a new way to cure CML.

Objective Preparation of specific antibody of neuron protein 14 3 3 and application for the diagnosis of prion diseases. Methods The rabbits were immunized with prokaryotic expressed GST 14 3 3 fusion protein and the collected antiserum was evaluated by ELISA and Western blot assays. Results ELISA revealed that the reactive titer of the prepared antibody against purified 14 3 3 protein was up to 1:4 096 000; Western blot assays confirmed that both prokaryotic expressed,and the natively presenting 14 3 3 proteins in the brain extracts were recognized by the prepared antibody. Two cases of clinically diagnosed Creutzfeldt Jakob disease (CJD)with typical EEG changes showed the positive 14 3 3 protein in cerebral spinal fluid (CSF). Four patients with dementia and narcoma but without typical EEG change were 14 3 3 negative in CSF,three of them being even further tested by brain biopsies without typical histological change of CJD and presentation of protease resistant PrP Sc protein. 35 samples CFS collected from patients without dementia were 14 3 3 negative in CSF. All the results were the same as that of standard 14 3 3 polyclonal antibody.Conclusion Using purified prokaryotic expressed GST 14 3 3 fusion protein as antigen,the specific antibody was elicited in the immunized animals. The prepared antibody can be used in identification of 14 3 3 protein in CSF for the diagnosis of CJD.

Objective To study the value of RDW in severity evaluation and prognostic assessment of COPD. Methods Retrospective study was carried out on 115 COPD patients and 50 healthy controls. Blood routine, CRP, IL-6 data were collected on admission aiming at analyzing RDW difference in patients and controls, severity, severity grading and evaluation of prognosis. Results The level of CRP, RDW, IL-6 and WBC in patients were higher than that of healthy controls(P < 0.05). Mild and moderate groups have no significant difference from each other in terms of RDW, CRP and IL-6 conparison, but the difference between any other two groups were significant. There were significant positive correlation between RDW and CRP, IL-6, and negative correlations between the post-bronchodilator FEV1% and RDW. The mortality rate for patients with higher RDW level was higher than those with normal RDW. Conclusion Elevated RDW levels on admission are associated with severity of patients with COPD. RDW may be a prognostic marker for COPD.

Objective To study the trends of injury mortality rates among residents in Dafeng city from 1976 to 2006, and provide a scientific basis for preventing and controlling injure. Methods The death registry data from 1976 to 2006 in Dafeng city was collected and its injury death trends was analyzed with joinpoint regression method and the relationships of injury mortality rates with sex, age and time were analyzed with Poisson regression method. Results A total of 13905 cases died from injuries in Dafeng city from 1976 to 2006. The gross injury death rate was 61.40 per 100 000, 70.18 per 100 000 in male and 51.85 per 100 000 in female (P

Objective To study the clinical,endoscopic an d pathologic features of primary gastric malignant lymphoma,and to improve its diagnostic efficiency.Methods The clinical,pathologic and endoscopic data in twenty two cases of primary gastric malignant lymphoma were retrospectively reviewed. Results In these cases,the common presentations include abdomi nal pain、anorexia、loss of weight etc. These patients were all examined by endo scopy with protruding,ulcerative and infiltrative lesions. Submucosal lesions w ith hypo echoes were found by endoscopic ultrasonography in six cases,and enlar ged lymph nodes were found on the exterior of stomach in two cases. Conclusion The primary gastric malignant lymphoma has a rather low incidence,and without specific clinical manifestations, hard to differentia te gastric ulcer from cancer through the manifestation in endoscopy. Further com bination of endoscopy, endoscopic ultrasonography and pathology are helpful to i ts correct diagnosis.

Objective To analyze the clinical data of henoch-schonlein purpura(HSP)in children and to conclude the clinieal featrues of HSP.Methods The clinieal features of 60 children with HSP were analyzed.Results(1)The age of onset of all the 60 children with HSP was from 3 to 14 yearn old,especially from 5 to 10 years and the female patients were more than the male patients(the ratewas 2:1).Of the 60 children,they developed HSP in the four seasons,especially in the spring and winter;most of the HSP patients revealed evident predisposing factors,mainly upper respiratory infection.(2)All the patients had typical purpura.80% had typical purpura as the presenting contancous sign.The distribution of rash in the lower extremitiees,buttock upper extremities and face was 100%,30%,13% and 7%.30% occurre,repeatedly.(3)Gastrointestinal involvement and arthritis occurred rate is 47% and 60%,respectively.Of all the patients,13% devdoped HSP nephritis manifested as isolated hematuria and/or protcinuria.Conclusion HSP has its own clinical and episodic features.It is not difficult to diagnose the typical case.HSPN is its serious syndrome,it should be long-term foflow-up of kidney conditions.
