[Objective]To discuss the surgical treatment of huge tumor invovled sacrum.[Method]A review of records in 18 patients with tumors invovled sacrum was made.Age at surgery averaged 43 years(range:31~65),eleven patients were male,seven patients were female.In this series,malignant tumor was in 14 cases,according to Enneking classification,these cases were classified toⅠA~ⅠB subtypies,which concluded chordoma(8 cases),giant cell tumor(5 cases)and osteochondroma(1 case).Benign tumor was in 4 cases with neurogenic tumor(3 cases)and aneurysmal bone cyst(1 cases).[Result]Over all,no patients were dead in the operation,no other major complications were occurred,the blood loss during surgery was 1 000 ml to 5 000 ml.All incisional wound were primary healing except 4 cases,two of them gained secondary closure after gluteus maximus pushing flap.Eighteen patients gained follow-up visiting,the average time of follow-up was 30 months,only 2 cases were tumor recurrence.[Conclusion]Huge tumors invovled sacrum present a great challenge,because of many organs surrounding sacrum invovled and complexity in anatomic region,sacrectomy of sacral tumor always complic generous blood loss,disorder of urination and defecation,disorder of sexual function et al.Abdominosacral approach can lead to a safer and relative radical local control of tumor,it is benefit to protect blood vessel and nerves.

ObjectiveTo review the surgical technique and outcome of intracranial angiographically occult vascular malformations (AOVM) hemorrhage. Methods40 patients with spontaneous intracranial hemorrhage episodes and accepted microsurgery were analyzed retrospectively. ResultsAll AOVMs were successfully resected. No operative death occurred.36 patients were followed up for mean 28 months. CT and/or MRI revealed no residual lesions. Most neurological complications improved postoperatively. 1 case demonstrated rebleeding in surgical site 48 months after operation. Another case, a follow-up MRI scan revealed a contralateral denovo lesion 44 months after operation.ConclusionA current neurosurgical procedure is a satisfactory method to prevents AOVMs rebleeding. Long-term follow-up evaluation is necessary despite the lesion has been totally resected.

Objective To investigate the effect of the whole course health education on heart rehabilitation of old patients with percutaneous coronary intervention(PCI).Methods One hundred and twentyone old patients with coronary heart disease who all underwent complete PCI in Tangshan Gongren Hospital from January 2008 to December 2009 were selected as our subjects.All subjects were randomly divided into the intervention group (60 cases) and the control group (61 cases).All patients were treated by PCI ± standard drug therapy.Patients in control group were given the conventional health education,while in intervention group were given the extending health education plus the conventional health education.Questionnaire was used to collect the coronary heart disease knowledge,recovery and secondary prevention behavior.The levels of blood pressure,density lipoprotein cholesterol,fasting blood glucose (FB) were measured at 6,12,24 months at discharge hospital.Meanwhile the reaching standard rate of coronary heart disease risk factors control was also used to evaluate the effect of education.Results The scores of knowledge of coronary heart disease rehabilitation of intervention group at 6,12 and 24 months after discharge were (79.69 ± 4.66),(83.26± 8.38),(81.81 ± 9.21) respectively,higher than that of control group ((72.36 ± 8.16),(69.96 ± 10.69),(70.00 ± 11.32) respectively),and there were significant differences between groups(t =3.26,5.39 and 4.41respectively,P ＜ 0.05).The scores of the second level prevention act of intervention group were (79.00±5.65),(79.88 ± 6.34) and (79.13 ± 11.21) respectively,higher than that of control group((70.72± 7.59),(68.84 ± 5.36) and (66.52 ± 9.15) respectively),and there was significant difference between groups (t =3.75,5.99 and 3.63 respectively; P ＜ 0.05).The reach standard rate of low density lipoprotein cholesterol(LDL-C),exercise of intervention group at 6 months were 60.0％ (36/60),65.0％ (39/60),higher than that of the control group(37.7％ (23/61),32.8％ (20.61)),and there was significant difference between groups(x2 =6.045,10.871,P ＜0.05),while there was no significant difference in terms of the reach standard rate of blood pressure,FB and quit smoking(P ＞ 0.05).The reach standard rate of blood pressure,LDL-C,FB,quit smoking,exercise of intervention group at 12 months were 75.0％ (45/60),76.6％ (46/60),96.6％(58/60),81.7 ％ (49/60),75.0％ (45/60),higher than that of control group (49.2 ％ (30/61),32.8 ％(20/61),80.3％ (49/61),57.4％ (35/61),31.1％ (19/61),and there was significant difference between groups(x2 =8.021,28.438,8.431,10.435 and 23.128 respectively,P ＜ 0.05).The reach standard rate of blood pressure,LDL-C,FB,quit smoking,exercise of intervention group at 12 months were (75.0％ (45/60),81.7％ (49/60),95.0％ (57/60),86.7％ (52/60),81.7％ (49/60)),higher than that of control group (44.3％ (27/61),31.1％ (19/61),75.4％ (46/61),47.5％ (29/61),34.4％ (21/61)),and there was significant difference between groups (x2 =11.710,35.810,8.112,25.450 and 25.650 respectively,P＜0.05).Conclusion Whole course health education is proved to reach the purpose of long-term heart rehabilitation,and decrease the risk of the risk factors for PCI.Meanwhile it is a safe,effective,compliant heart rehabilitation model after PCI in old patients.

Objective: Fetal monitoring is extremely important in perinatal care. Analysis of cardiotocogragh(CTG) can suppose if the fetus is lack of oxygen, distressed, acidosis, etc. in order to take measures timely. Methods: We have designed Meticare analysis software package to analyze 867 pieces of CTG data, and researched the relationship between short term variation (STV) and basal heart rate(BHR) by statistics, and short time monitoring analysis based on STV. Results: The amplitude of fetal heart rate curve variation(long term variation) tended to decrease when BHR increasing, with the negative correlation and regression equation STV = 9.866-0.02×BHR. Positive correlation exists between 5 and 10 mimute-STV, with the regression equation STV_(10min)=2.861-0.596×STV_(5min).Conclusion: STV calculated by 5 minutes CTG data can forecast the one by 10 minutes data as a reference demanded by Dawes & Redman criterion. If fetal doppler contains STV analysis function, out-patient fetal heart auscultation will be more significant. After 30 weeks pregnancy, with the STV decreasing, fetal distress, asphyxia, low birth weight, and even mortality increasing. BHR increasing should cause attention that STV might decrease, when monitoring with no analysis functional devices or fetal dopplars.

BACKGROUND: Changing the local environment of spinal injury promotes the repair and regeneration of injured nerve and recovery of partial nervous function of spinal cord. Transplantation of olfactory ensheathing cells can improve the local internal environment of injured spinal cord.OBJECTIVE: To probe into the effect and safety of transplantation of olfactory ensheathing cells on functional repair of spinal cord and nerve in patients with obsolete spinal injury DESIGN: Self-control experiment.SETTING: Wards of the Department of Surgery, Taian Rongjun Hospital of Shandong Province.PARTICIPANTS: Totally 48 patients admitted for obsolete spinal injury in the Department of Surgery, Taian Rongjun Hospital, between June 2004 and July 2005 were recruited. There were 39 males and 9 females, aged 7 to 59 years with the mean of 36 years.METHODS: ①Cell culture: Olfactory bulb of aborted fetus was digested into single olfactory ensheathing cells, which were then cultured and puri fied for 1 to 2 weeks, and finally made into single cell suspension. ②Operation and cell transplantation: Under general anesthesia, the purified single cell suspension (about 0.05-0.20 mL) of olfactory ensheathing cells was injected into the corresponding spinal injury site through multiple points with home-made syringe of 0.45 mm in diameter. Stitches were taken out at postoperative 10 to 14 days. ③Evaluation of spinal function: Injury Scoring Standard made by American Spinal Injury Association (ASIA) was used for scoring, comparison and statistical analysis at postoperative 1 day and 2 weeks to 2 months. ④Spinal function of 48 patients was observed or followed up through telephone at postoperative 3 weeks to 1 year.MAIN OUTCOME MEASURES: Changes of postoperative sensory function of the patients. Changes of postoperative motor function of the patients. Changes of postoperative automatic nervous system of the patients.RESULTS: ①All the 48 patients had improvement in spinal function, and continued improved tendency was found in the observation and follow-up through telephone at postoperative 3 weeks to 1 year. ②Scoring by ASIA for sensory function was higher after operation than before operation (touch sensation: 56.9, 51.2, P ＜ 0.01; pain sensation: 55.2, 48.3, P ＜ 0.01). Sensory function was improved obviously at the lower shift of sensory level,generally more than 2 segments. ③Scoring by ASIA for motor function was higher after operation than before operation (44.8, 40.7, P ＜ 0.01), but the improvement was slow. ④Scoring by ASIA for automatic nervous system was higher after operation than before operation (18.0, 14.5, P ＜ 0.01); diaphoresis, increased enterokinesia and other automatic nervous system improved earliest.CONCLUSION: Transplantation of olfactory ensheathing cells promotes the spinal and neurofunctional recovery of patients with malignant spinal injury, and the therapeutic method is safe.

OBJECTIVE: To investigate the effects of Qinggan Huoxue Recipe (QGHXR), a compound Chinese herbal medicine, and its decomposed formulas Qinggan Recipe (QGR) and Huoxue Recipe (HXR) on expressions of CD14, Toll like receptor 4 (TLR(4)) and nuclear factor-kappaB (NF-kappaB) in Kupffer cells. METHODS: The isolated primary rat Kupffer cells were treated with lipopolysaccharide (LPS) for a certain period of time, a series of concentrations of drug-containing serums of QGHXR and its decomposed formulas were added, the expressions of NF-kappaB, tumor necrosis factor-alpha (TNF-alpha), CD14, and TLR(4) of the Kupffer cells were detected in different culture conditions by using Western blot, real-time reverse transcription polymerase chain reaction (RT-PCR) and ELISA methods respectively. RESULTS: QGR could down-regulate the expression of membrane receptor CD14, but the expression of NF-kappaB and TNF-alpha were not significantly decreased after QGR treatment. HXR could down-regulate the expression of membrane receptor TLR4 and inhibit the expressions of NF-kappaB and TNF-alpha. QGHXR could down regulate the expressions of membrane receptors CD14 and TLR(4) and inhibit the expressions of NF-kappaB and TNF-alpha. CONCLUSION: QGHXR can protect liver cells by down regulating the expressions of CD14, TLR(4) and NF-kappaB and inhibiting TNF-alpha expression.

OBJECTIVE: To establish a model of alcoholic liver fibrosis (ALF) in rats induced by complex factors. METHODS: Forty-seven healthy male rats were divided into three groups: normal control group (n=12), minor CCl4 group (n=12) and complex factors group (n=27). The rats in the complex factors group were fed a complex diet including alcohol, corn oil and pyrazole, and administered with intraperitoneal injection of minor CCl4 to induce ALF. During induction process, the histopathological changes of liver tissue and the values of liver-to-body weight ratio were both observed regularly. The serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST) and gamma-glutamyltransferase (gamma-GT) in these three groups were all examined at the 12th week of the induction process. RESULTS: At the 12th week of the induction process, the model of ALF induced by complex factors was successfully established in rats, and the histopathological presentations showed alcoholic fatty liver, hepatitis and liver fibrosis in a sequence along with the induction process. The value of liver-to-body weight ratio and the serum levels of ALT, AST and gamma-GT of rats in the complex factors group were all significantly different from those in the other two groups. CONCLUSION: It is a steady and effective way to induce ALF in rats with complex diet and minor CCI4 injection.
