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 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.

AIM: To study the role of post-hemorrhagic shock mesenteric lymph (PHSML) drainage on the balance of angiotensin-converting enzyme ( ACE) and ACE2 in the kidney.METHODS:A hemorrhagic shock model was established and then fluid resuscitation was performed to the animals in shock and shock+drainage groups, and the PHMSL was drained in shock+drainage group after fluid resuscitation.After 6 h of resuscitation, the mRNA expression of ACE, ACE2, angiotensin II (Ang II) type 1 receptor (AT1R) and Mas-related G-protein-coupled receptor (MasR), and the levels of Ang II and Ang (1-7) in the renal tissues were observed.RESULTS:Hemorrhagic shock increased the levels of ACE mRNA, AT1R mRNA and Ang II, and decreased the levels of ACE2 mRNA, MasR mRNA and Ang(1-7) in the kid-ney.PHSML drainage abolished the effect of hemorrhagic shock on ACE2 and AT1R mRNA expression.Meanwhile, PHSML drainage reduced the hemorrhagic shock-induced increases in the ratios of ACE/ACE2, Ang II/Ang(1-7) and AT1R/MasR.CONCLUSION:The PHSML drainage restores the balance of ACE/ACE2, which is beneficial to alleviate acute kidney injury following hemorrhagic shock in the mice.

A 13-year-old girl presented with multiple recurrent cutaneous plaques for more than six months,which had been aggravated with intermittent fever for five months.No obvious systemic abnormality was found.Dermatological examination revealed multiple,non-ulcerative,painless,infiltrative,indurated,poorly marginated,purple subcutaneous plaques measuring 3-1 1 cm in diameter with slight squamation in bilateral buttocks and lower limbs.Laboratory investigations showed bicytopenia with the white blood cell count being (0.03-3.7) × 109/L and red blood cell count being (2.8-4.4) × 1012/L,a normal platelet count,hypofibrinogenemia (1.79 g/L) and low proportion of natural killer cells (4.6％).Bone marrow smear showed active proliferation of cells,decreased proportion of granulocytes,presence of a few indefinitely classified cells,and phagocytosis.Reticulocytes were easily seen in the bone marrow smear.Pathologically,no obvious abnormality was observed in the epidermis or dermis,while the subcutaneous adipose tissue,especially fat lobules and some interlobular septa,was extensively infiltrated by large-to medium-sized lymphoid cells with pleomorphic and twisted nuclei as well as a small amount of cytoplasm; necrosis and phagocytosis of nuclear debris and lymphocytes were visible.The atypical lymphoid cells stained positive for CD3,T-cell intracellular antigen-1,granzyme B and TCRγδ with partial loss of CD5 and CD7,but negative for CD56,CD4,CD8 and TCRαβ.No Epstein-Barr virus-encoded RNA (EBER) was detected by in situ hybridization.Based on these findings,a diagnosis of primary cutaneous γδ-T cell lymphoma with hemophagocytic syndrome was made.

AIM: To observe the changes of morphology, the activity of myeloperoxidase (MPO) and membrane pump activities of spleen tissue in acute renal failure (ARF) rabbits, and to inquire into the role of spleen on pathogenesis of immune function disorders during ARF. METHODS: 42 rabbits were divided into control group, HgCl_2 group and glycerinum group. The ARF model was established by hypodermic injection of 1% HgCl_2 at dose of 1.3 mL/kg in HgCl_2 group, intramuscularly injection of 50% glycerinum at dose of 10 mL/kg in glycerinum group, respectively, and the animals were divided into the 12 h, 24 h, 48 h secondary groups (6 rabbits each group). At different time points, the rabbits were cannulated to facilitate the collection of blood sample to examine the biochemical indexes of renal function. The spleen microscopic sections were prepared for observing the morphology. The spleen homogenate was made for determining the activities of MPO and membrane pumping. RESULTS: Pathological sections of spleen showed that the different degree of congestion was found and spleen trabecula was increased in two model groups at multiple-time points. The MPO activity of spleen homogenate in HgCl_2 group and glycerinum group at all time points were obviously higher than that in control group, and at 24 h, the MPO activitie in two model groups was significantly increased than that in the same group at 12 h and 48 h. The activities of Na~+-K~+-ATPase, Ca~(2+)-ATPase, Mg~(2+)-ATPase, Ca~(2+)-Mg~(2+)-ATPase of spleen homogenate in two model groups at multiple time points were significantly lower than those in control group. Following ARF development, the ATPase activitie in two model groups at 48 h was lower than that at 12 h except the Mg~(2+)-ATPase in glycerinum group. CONCLUSION: Spleen as an immune organ has histological damage, arrest of polymorphonuclear neutrophils and dysfunction of membrane pump during the development of ARF in rabbits, leading to immune disorders.
