Objective To investigate the clinical features of early postoperative inflammtory small bowel obstruction,and discuss its diagnosis,treatment and preventive measures.Methods The clinical data of 68 cases of early postoperative inflammatory small bowel obstruction were analyzed retrospectively.Results Within the 68 cases,65 cases were cured by non-operative treatment including gastrointestinal decompression,anti-inflammatory drugs,somatostatin,total parenteral nutrition(TPN) and traditional Chinese medicine.The mean time from the onset of symptoms to the recovery of bowel function was 14 days.Three cases were cured by transferring to operation.One case of them was transferred to operation for strangulated intestinal obstruction during the period of conservative treatment.One case underwent oper.ion because the patient didn t recover after 4 weeks expectant treatment.One case underwent operation for the impatience with the conservative treatment of both the doctors and the patient.Conclusion Non-operative therapy should be the first choice for the treatment of early postoperative inflammatory small bowel obstruction,and its therapeutical effect was well-accepted.

Objective To compare clinical effect of MTA and Vitapex for young permanent teeth with periapical incomplete apical closuret . Method Teeth 90 were chosen from 80 patients at 7-25 years old young permanent teeth with periapical and randomly divided into MTA group and Vitapex group 45 in each group.Two groups were treated with MTA and Vitapex paste treatment respectively.6-month and 12-month after treatment followed up, observed clinical efficacy of two groups.Results The six-month recall, X-ray ( MTA group 93.33%, Vitapex group 88.89%) and clinical parameters (MTA group 95.56%, Vitapex group 86.67%) success rate of two group was no significant difference.When the 12-month followed up, X-ray examination of MTA group's success rate was 93.33%, significantly higher than 68.89%Vitapex group (P<0.05), clinical indicators of success rate of 95.56%MTA group,significantly higher than the 71.11%Vitapex group (P<0.05).Pain during root canal therapy (EIP) of the occurrence, MTA group than Vitapex group (P<0.05).Conclusion The effect of short-term treatment of MTA in treatment of young permanent teeth with periapical incomplete apical closure is definite,it is an ideal induce apical molding material.

ObjectiveTo study the clinical features of stercoral bowel obstruction and perforation of colon in elderly patients MethodsThe data of 22 cases of stercoral bowel obstruction and 6 cases of stercoral perforation of colon in elderly patients in our hosital from January 1994 to December 2003 were analyzed retrospectively ResultsIn the 22 cases with stercoral bowel obstruction, 6 cases were recovered after operation, 6 cases suffered from stercoral perforation in which all cases were misdiagnosed before operation,and 2 cases were dead.ConclusionsThe prevalence of stercoral bowel obstruction and perforation of colon in elderly patients are increasing with population being aged. The cases without perforation are often recovered by non-operative therapy. The perforation case of stercoral bowel obstruction is relatively rare, easy to be misdiagnosed, and in high mortality. The Hartmanns ostomy should be the choice for the perforation.

Objective To survey the value of risperidone in the treatment of depression without psychotic symptoms. Methods 205 depressive patients were randomly divided into 3 groups: risperidone group, fluoxetine group and combined group (risperidone+fluoxetine). They were assessed with Hamilton Depression Scale (HAMD), Treatment Emergent Symptom Scale (TESS) before treatment and in 2nd week, 4th week, 6th week and 8th week after treatment. Results The reduction rate of HAMD of combined group was the best among three groups(P<0.05), and that of fluoxetine group was better than that of risperidone(P<0.01). The significant difference in reduction rate of HAMD between combined group and other two groups was observed since 2nd week after treatment(P<0.05). No difference in scores of TESS has been observed in any time among three groups. Conclusion Risperidone can improve the efficacy of fluoxetine on depression without psychotic symptoms without increasing side effects, but itself is less effective than fluoxetine.

Surgical shunt is still an effective method in managing portal hypertension related gastrointestinal bleeding.To minimize the invasive trauma and adverse effect on transplantation remains to be the unsolved problem.Herein we present the use of a newly designed surgical shunt to cure massive refractory gastrointestinal tract hemorrhage in a patient,who was critically ill because of the extensive thrombus in portal venous system.The procedure is named gastrojugular shunt.For the sake of its simple operation and effective outcome,the procedure was performed on four other patients.All the patients were well treated and recovered uneventfully with good follow up results.

Object To demonstrate the naked truth of four therapeutic features of TCM (cold, hot, warm and cool) from biophysical and biochemical point of view. Methods Growth thermogenesis curves of Escherichia coli were determined under different conditions by microcalorimetry to give biothermodynamic parameters, such as multiplication constant (k), median inhibitory concentration (IC 50 ), and enthalpy (?H). Differences between folia ginseng and flos ginseng were comprehensively compared with reference to classical Chinese literatures on material medica. Results The bacteriostatic curve of both drugs were basically similar. With increasing concentration of decoctions of both drugs, the lag phase was delayed and the peaks shifted to the right. While the difference of ?H was stable, which decreases with the increasing concentration of Folium ginseng, but increases with increasing concentration of Flos ginseng. Conclusion Microcalorimetry is not only a new effective method to describe the therapeutic features of TCM, but also could be used as a tool for the screening of active TCM.

OBJECTIVE: To investigate the influence of intra cranial pressure (ICP) and cerebral perfusion pressure (CPP) on neurological det erioration and outcome of severe traumatic brain injury (STBI). METHODS: A total of 245 patients with severe traumatic brain in jury were studied retrospectively with univariate and multivariate studies to ev aluate the contribution of ICP/CPP to neurological deterioration and outcome. RESULTS: The mortality rates rose from 16.2% in 142 patient s whose course of disease was smooth to 66.7% in 103 patients who suffered f rom neurological deterioration. Correspondingly, the favorable outcome fall from 54.2% in the patients without neurological deterioration to 18.3% in th ose with neurological deterioration. In the patients with clinical evidence of n eurological deterioration, the relative influence of the ICP and the CPP on outc ome was assessed. The most powerful predictors of neurological deterioration was the presence of intracranial hypertension (ICP>30 mm Hg, 1 mm Hg=0.133 kPa). The CPP also had a prognostic power on neurological deterioration when its level less than 60 mm Hg. CONCLUSIONS: It suggests that it's very important to lower the intracranial hypertension and keep the CPP not less than 60 mm Hg during the t reatment of STBI.

Objective To investigate the effects of sevoflurane pretreatment on the inflammatory response in patients undergoing cardiac valve replacement with cardiopulmonary bypass (CPB) and the mechanism of myocardial protection.Methods Twenty NYHA class Ⅱ or Ⅲ patients of both sexes,aged ＜ 60 yr,undergoing cardiac valve replacement with CPB,were randomly divided into 2 groups (n=10 each): sevoflurane group (group S) and control group (group C).The patients were premedicated with intramuscular morphine 0.1 mg/kg and scopolamine 0.3 mg.Anesthesia was induced with iv injection of midazolam 0.05-0.08 mg/kg,fentanyl 10-15 μg/kg and pipecuronium 0.08-0.10 mg/kg.The patients were tracheal intubated and mechanically ventilated.Anesthesia was maintained with intermittent iv boluses of midazolam0.03-0.06 mg/kg,fentanyl 5-10μg/kg and pipecuronium 0.04-0.08 mg/kg.Sevoflurane was inhaled before aortic clamping and the end-tidal concentration was rapidly adjusted to 1.0％ and maintained at this level for 30 min in group S.Blood samples were taken from the central vein before skin incision,immediately after aortic clamping,immediately after aortic unclamping and at 30 min after aortic unclamping,at 2,6,12 and 24 h (T1-8) after operation for determination of the concentrations of plasma tumor necrosis factor-α (TNF-α),interleukin-6 (IL) and interleukin-8 (IL-8),intercellular adhesion molecule-1 (ICAM-1),cardiac troponin I (cTnI) and activity of creatine kinase MB (CK-MB).The requirement for cardiovascular drugs was recorded after release of aortic cross clamp.Results Compared with group C,the plasma concentrations of TNF-α,IL-6 and IL-8 were significantly decreased at T3-8,the plasma concentrations of ICAM-1 and cTnl were significantly decreased at T4-8,the activity of plasma CK-MB was significantly decreased at T8,and the requirement for cardiovascular drugs was significantly reduced after release of aortic cross clamp in group S (P ＜0.05).Conclusion Sevoflurane pretreatment can inhibit the inflammatory response and provide myocardial protection to some extent in patients undergoing cardiac valve replacement with CPB.

ObjectiveTo explore the cognitive psychological characteristics of the insomniac and the effect of cognitive therapy.Methods93 insomniac in-patients were divided randomly into the trial group (n=47) and control group (n=46). The trial group was treated by cognitive therapy plus medicine. The control group was only treated with medicines. The treatment lasted for 8 weeks. Before and after treatment, patients of all two groups were examined by Beliefs and Attitudes about Sleep Scale (DBAS). 45 healthy individuals were also examined at the same time. The therapeutic effect was evaluated with Pittsburgh Sleep Quality Index (PSQI).ResultsBefore treatment, DBAS scores of insomniacs were significantly different from the healthy (P<0.001). After treatment, scores of DBAS and PSQI of the trial group were significantly different from that of the control group ( P<0.001).ConclusionThe cognitive treatment can change erroneous cognitions related to sleeping in the insomniac and improve the therapeutic effect.

Objective To investigate the effects of sevoflurane pretreatment on the myocardial injury in patients undergoing cardiac valve replacement with cardiopulmonary bypass (CPB).Methods Twenty NYHA class Ⅱ or Ⅲ patients,aged ＜ 60 yr,undergoing cardiac valve replacement with CPB,were randomly divided into 2 groups (n =10 each):sevoflurane group (group S) and control group (group C).The patients were premeditated with intramuscular morphine and scopolamine.Anesthesia was induced with iv injection of midazolam 0.05-0.08 mg/kg,fentanyl 10-15 μg/kg and pipecuronium 0.08-0.10 mg/kg.Anesthesia was maintained with intermittent iv boluses of midazolam,fentanyl and pipecuronium and in addition sevoflurane was inhaled before aortic clamping and the end-tidal concentration was rapidly increased to 1.0％ and maintained at the level for 5 min in group S.Blood samples were taken from the central vein before skin incision (T1),immediately after aortic clamping (T2 ),at 0 and 30 min after aortic unclamping (T3-4),and at 2,6,12 and 24 h after operation (T5-8) for determination of the concentration of serum cardiac troponin Ⅰ (cTnI) and activities of creatine kinase (CK) and creatine kinase isoenzyme-MB (CK-MB).Myocardial specimens were taken from right auricle before aortic clamping and at 10 min after aortic unclamping for electron microscopic examination.Results The concentration of serum cTnI and activities of CK and CK-MB were significantly increased at T4-8 in both groups ( P ＜ 0.05).The serum cTnI concentration at T4-8 and the activities of CK and CK-MB at T8 were significantly lower in group S than in group C ( P ＜0.05).Different degrees of mitochondrial swelling were observed after aortic unclamping in both groups,but the changes were milder in group S than in group C.Conclusion Sevoflurane pretreatment can attenuate the myocardial injury in patients undergoing cardiac valve replacement with CPB.
