Objective To observe the anatomy of the inferior right hepatic veins (IRHV).Methods The IRHVs were divided into 3 groups according to the location where they entered into the retrohepatic inferior vena cava at: the upper 1/3, middle or lower 1/3. The incidence, number, caliber, extrahepatic length and the relationship between the major hepatic veins (the right, middle and the left hepatic veins) and the IRHV were observed and measured in 60 adult cadavers. Results The incidence of IRHV was 83.33% with an average diameter of 2.62-18.46(14.32±1.21)mm. Its extrahepatic length was 3.26-47.65 (10.78±7.81)mm. There was a marked negative correlation between the diameter of the IRHV and its number, a marked negative correlation between the diameter of the IRHV and the diameter of the right hepatic vein and a marked positive correlation between the number of the IRHV and the diameter of the right hepatic vein. Conclusions There were high variations in the incidence and anatomy of the IRHV which were related to the diameter of the right hepatic vein. The IRHV was not to be torn during liver resection and should be reconstructed in right liver grafts.

Objective To observe the post-operative analgesic effect of flurbiprofen Axetil applied preoperatively on patients with spinal cord injury(SCI).Methods46 SCI patients undergoing spine surgery under general anesthesia were randomly divided into the flurbiprofen axetil group(group F)and control group(group C)with 23 cases in each group.Before cutting skin,flurbiprofen axetil(1 mg/kg)was injected intravenously in the group F,and normal saline(1 ml/kg)was infected intravenously in the group C.The scores of Visual Analogue Scale(VAS)for pain at postoperative 2,4,8,24,and 48 hours,and the incidence of side effects within 48 hours after operation were recorded.ResultsVAS scores at the time of 2,4,8,and 24 h after operation in the group F were significantly lower than that in the group C(P<0.05).But VAS scores of two groups at 48 h were not significantly different(P>0.05).The incidences of side effects of two groups were also not significantly different(P>0.05).ConclusionFlurbiprofen axetil applied preoperatively can release pain of SCI patients after spine surgery,and does not increase the incidence of side effects.

Objective To compare the characteristics of total intravenous anesthesia (TIA) with manual assisted ventilation and combined inhalation and intravenous anesthesia (CIIA) with mechanical ventilation in lower limbs orthopedics for patients with cerebral palsy.Methods 50 patients with cerebral palsy undergoing scheduled lower limbs orthopedics were randomly divided into the TIA group and CIIA group with 25 cases in each group. The patients of the TIA group were treated with manual assisted ventilation. Those of the CIIA group were treated with fast induction, endotracheal intubation, inhalated and intravenous anesthetics maintaining the anesthesia and mechanical ventilation. The recovery time after operation and post-operative side effects including nausea, vomiting, and psychomotor agitation of all patients were observed.Results The recovery time of the patients in the CIIA group was significantly longer than that in the TIA group ( P<0.01), and post-operative psychomotor agitation was significantly higher than that in the TIA group ( P<0.05). However, there was no significant difference in nausea or vomiting found between two groups ( P>0.05).Conclusion Patients treated with TIA is easier to recovery and has fewer side effects than those treated with CIIA.

ObjectiveTo compare the effect of rehabilitation training after surgical intervention of knee stiffness (SIKS) between femoral nerve block (FNB) and epidural nerve block (ENB).Methods60 patients undergoing SIKS at one knee joint were randomly assigned to two groups: 40 patients accepting a catheter for FNB in group A and 20 patients accepting a catheter for ENB in group B. All patients participated in passive rehabilitation therapy (PRT) and active rehabilitation therapy (ART) at 12 hours, 24 hours, 36 hours, and 48 hours after operation. 10 ml of lidocaine were applied via these catheters before rehabilitation therapy. The visual analogue score (VAS) for pain in PRT, the time needed from the end of PRT to the start of ART, and the incidence of side effects such as hypotension or nausea were recorded.ResultsThere was no significant difference in VAS between groups A and B. The time needed from the end of PRT to the start of ART in group A was significantly less than that of group B. The incidence of hypotension or nausea in group A was significantly less than those of group B.ConclusionFNB provides the same analgesic effect as ENB, has less time needed from the end of PRT to the start of ART, and lowers incidence of hypotension or nausea.

Objective To investigate the carbohydrate metabolism during selective posterior rhizotomy (PCR) at lumbar and sacral regions on cerebral palsy children (CPC).Methods62 CPC who received SPR at lumbar and sacral regions under combined intravenous and inhalation anesthesia were tested with the level of glucose (Glu) in plasma at different time during the operation.Results and ConclusionThere is no significant difference of Glu at different time during the operation, however, the Glu level shows an elevating trend at 3 and 10 minutes after posterior root electric stimulation.

Objective To observe the effect of ropivacaine in infiltration anesthesia before the end of surgical procedures for postoperative analgesia on patients with spinal cord injury. Methods 60 patients with spinal cord injury undergoing internal fixation of spine fractures under combined general anesthesia were assigned in 3 groups, who received 0.25% ropivacaine in infiltration anesthesia (group RL, n=20),0.5% ropivacaine in infiltration anesthesia (group RM, n=20), or no infiltration anesthesia (group C, n=20) before the end of surgical procedures.The time for post-anesthesia recovery (PART), agitation score (AS), and Visual Analogue Score (VAS) for pain 2 h, 6 h, 24 h, and 48 h post operation were recorded, and related side effects were observed. Results AS within 6 h postoperation was significantly less in group RL and RM than in group C (P<0.05), as well as VAS, PART, mean of arterial pressure and heart rate 2 h, 6 h, and 24 h post operative (P<0.05).There was no significant difference in side effects including postoperative nausea and vomiting, and pruritus among these groups (P>0.05). Conclusion Ropivacaine in infiltration anesthesia would provide better postoperative analgesia, decrease the incidence of postoperative agitation, and increase the safety of patients with spinal cord injury in the postoperative period.

Objective To observe the effect of intravenous pre-injection of neostigmine on cardiovascular response(CVR) caused by neuromuscular electrical stimulation(NMES) in selective posterior rhizotomy(SPR) for patients with cerebral palsy.Methods 56 patients with cerebral palsy undergoing SPR at lumbarsacral segments under general anesthesia were randomly assigned to 2 groups: intravenous neostigmine 0.04 mg/kg(no more than 1 mg in total) and intravenous atropine 0.02 mg/kg(no more than 0.5 mg in total) 5 min before NMES in group N,and intravenous normal saline 0.12 ml/kg instead in group C.The systolic blood pressure(SBP) and heart rate(HR) at following time points: before skin incision(T1),before intravenous neostigmine/atropine or normal saline injection(T2),1 min after NMES(T3),and 10 min after NMES(T4).Results SBP and HR at T3 in group N were significantly lower than those in group C(P<0.01).No significant difference was found at T1,T2 and T4 between two groups(P>0.05).Cases who needed extra dose of fentanyl during NMES in group N were significantly lower than those in group C(P<0.01).Conclusion Intravenous pre-injection of neostigmine before NMES can effectively decrease the CVR caused by NMES.

BACKGROUND: It has become a hot issue to treat malignant tumors with retroviral mediated cytokines. But it remains a controversy whether retroviral mediated γ-interferon(IFN-γ) is valid in killing glioma cells and prolonging the survival of tumor carriers.OBJECTIVE: To observe the effect of retrovital mediated γ-interferon on the growth of glioma and the survival of tumor-carrying rats.DESIGN: Completely ramdomized trial based on animals.SETTING: Neurosurgery department of a hospital affiliated to a university.MATERIALS: The trial was conducted in the Neurosurgery Institute of Harbin Medical Unicersity from July 2002 to July 2004. The subjects were 60 male Wistar rats provided by the Animal Center of the First Affiliated Hospital of Harbin Medical Unicersity. They were randomly assigned into 3groups: C6 control group, C6/PA317neo control group and C6/PA317IFN-γ treatment group, 20 in each group.INTERVENTIONS: Retroviral vector containing murine IFN-γ gene was transferred into retroviral package cell PA317. A high titer PA317IFN-γ cell line was obtained after G418 resistance screening. In the right basal ganglion area 1 × 106 C6 cells was injected in each of the rats. The rats in C6groups received no more intervention. Those in C6/PA317neo control group received injection of 1 × 106 PA317IFN-γ cells in the right basal ganglion 4days after C6 injection. Those in C6/PA317IFN-γ treatment group received injection of 1 × 106 PA317IFN-γ cells in the right basal ganglion 4 days after selected from each group to be kill, and the brains were taken out to make frozen sections for SABC immunohistochemical staining. The CD4 and CD8 T was measured with imaging processing software under microscope.RESULTS: The mean survival time of rats in C6 and C6/PA317neo control groups was(27.10 ± 0.82) days and (26.60 ± 0.93) days respectively( P ＞ 0.05), while that in treatment group was(49.30 ± 4. 17) days and there were five rats outlived beyond 60 days( P ＜ 0.01 vs the two controls). The tumor volume in the two control groups was of no difference but the tumor volume in treatment was significantly smaller than that in control groups( P ＜ 0. 01 ) . The CD4 and CD8 lymphocytes infiltration in treatment group was more than that in control groups( P ＜ 0.01) and there was no difference between the two controls( P ＞ 0.05) . It was also revealed through immunohistochemical examination that in treatment group there was Brdu positive cells on the 7th day and they disappeared on the 16th day. But there was no Brdu positive cells in the control groups.CONCLUSION: Intratumor injection of PA317IFN-γ induces anti-tumor immunal reaction in rats. Retroviral mediated IFN-γ inhibits tumor growth and prolongs rat survival.
