Objective To establish a quantitative biomechanical relationship between the anterior cruciate ligament deficiency and the posterior horn of medial meniscus. Methods 10 human cadaveric knees were examined using an in vitro knee-testing apparatus. In response to a combined 134 N anterior and 200 N axial compressive tibial load, the in situ forces in the posterior horn of medial meniscus were measured. Testing was performed on 10 knees at multiple angles of flexion (30?, 60?, 90?) before and after resection of anterior cruciate ligament. Results The resultant forces on the posterior horn of medial meniscus were as follows: intact ACL knees, (22.8?11.5) N in 30? flexion, (27.1?16.3) N in 60? flexion, (26.7?14.5) N in 90? flexion. ACL deficiency knees, (87.3?43.9) N in 30? flexion, (77.7?43.3) N in 60? flexion, (66.2?40.1) N in 90? flexion. The resultant forces significantly increased as a result of ACL deficiency(P

Chinese Journal of Primary Medicine and Pharmacy 2006;0(10):-
Objective To investigate the pathogen distribution and drug sensitivity in childhood bacillary dysentery,and to guide clinically the selection of reasonable antibiotics.Methods Bacterial drug susceptibility test was performed by standard Kirby-Bauer method.The results were interpreted according to NCCLS 2002.Results Of the 98 cases,there were two types of positive bacterial species:sh.flexneri(n = 77)and sh.sonnei(n = 21).Both sh.flexneri and sh.sonnei were sensitive to cefoperazone,eeftazidime,ceftriaxone,cefoperazone/sulbactam and fura- zolidone,and insensitive to ampicillin and co-trimoxazole.Conclusion sh.flexneri was the major pathogen of child- hood bacillary dysentery.The third generation cephalosporins were the first choice for shigella infections.

Objective:To investigate the clinical application value of argon-helium knife cryoablation combined with radioactive seed implantation in the treatment of non-small cell lung cancer(NSCLC).Methods:A total of 117 patients with NSCLC admitted to Oncology Department of Fifth Affiliated Hospital of Zhengzhou University from January 2015 to January 2017 were included in our study.And they were divided into the combination group(n=63)treated with CT guided argon-helium knife cryoablation combined with radioactive 125I seeds implantation and the control group(n=54)treated only with argon-helium knife ablation.The changes of blood routine indexes, tumor markers, tumor ablation target volume and CT value were observed before and 1, 3, 6 months after treatment.Adverse reactions during treatment and the evaluation results of efficacy were compared between the two groups.Patients were followed up for 24 months to observe the recurrence and survival rates between the two groups. Results:In the combination group, seeds of(12.49±4.91)were implanted, and the X-ray exposure was(123.16±42.75)Gy.There was no significant difference in general clinical data between the two groups before treatment( P>0.05). At 1, 3 and 6 months after treatment, as compared with control group the combination group showed the significantly decreased platelet count( t=3.154, 3.586, 2.233, P=0.027、0.019、0.034), while, there was no significant difference in white blood cell count, red blood cell count and hemoglobin level between the two groups(all P>0.05). The levels of carcinoembryonic antigen(CEA), neuron-specific enolase(NSE)and tumor volume were significantly lower in combination group than in control group at 3 and 6 months after treatment( t3=3.142, 2.926 and 4.281, t6=4.094, 5.382 and 4.535, all P<0.05), showing significant improvements of illness.While, the above levels showed no significant differences at 1 month after treatment between two groups( t=1.065, 1.037, P=0.197, 0.255). At each monitoring time, the CT value of tumor target area showed a steady downward trend( P<0.05). During the treatment, the incidence of thrombocytopenia was higher in the combination group than in the control group(47.6% or 30/63 vs.24.1% or 13/54, χ2=6.935, P=0.008), while there were no significant differences in the incidence of postoperative fever, pneumothorax, myoglobinuria, pain, bleeding and nausea and vomiting between the two groups(all P>0.05). After 6 months of treatment, the remission rate was higher in the combination group(73.0% or 46/63)than in the control group(48.1% or 26/54). The survival time and relapse-free time of the combination group were longer than those of the control group[(21.81±4.31)months vs.(18.93±5.94)months, (20.48±5.76)months vs.(16.93±7.14)months, Log Rank χ2=8.229 and 9.656, P=0.004 and 0.002)]. Conclusions:Argon-helium knife Cryoablation combined with radioactive seed implantation can effectively control the local progression of NSCLC, reduce the risk of tumor recurrence, and has high safety.

Two new sesquiterpenoids, named as tyromols A and B (1 and 2), were isolated from cultures of basidiomycete Tyromyces chioneus, along with two previously reported 15-hydroxy-6 α, 12-epoxy-7β, 10αH, 11βH-spiroax-4-ene (3) and agripilol C (4). Compounds 1-4 were separated and purified by silica gel, RP-18, Sephadex LH-20 column chromatography. Their structures were elucidated on the basis of extensive spectroscopic analysis including IR, MS, 1D and 2D NMR experiments.

[ ABSTRACT] AIM:To investigate the combined effect of octreotide and Dachaihu decoction on the treatment of severe acute pancreatitis (SAP).METHODS:Wistar rats (n=50) were randomly divided into sham group, SAP group, octreotide group, Dachaihu decoction group and combination group.The quantity of ascites was measured.The levels of amylase, alanine aminotransferase and creatinine in the serum were examined.The morphological changes of the pancreatic tissues were observed by HE staining.The activation of NF-κB and IκBαexpression were determined by Western blot.The mRNA expression with ICAM-1 and IL-1 was detected by qPCR.RESULTS: Combined treatment with octreotide and Dachaihu decoction effectively reduced the quantity of ascites and the levels of amylase, alanine aminotransferase and creat-inine in the serum in SAP rats.Moreover, combined treatment significantly inhibited SAP-induced activation of NF-κB and decrease in IκBαprotein expression, accompanied by a decrease in ICAM-1 and IL-1 mRNA expression.CONCLU-SION:Combination of octreotide with Dachaihu decoction effectively attenuates SAP by inhibiting NF-κB signaling pathway and ICAM-1 and IL-1 expression.

Objective To analyze the mierosurgery treatment and prognosis of cavernous hemangioma loca-ted in pons. Methods 12 cases with cavernous hemangioma located in ports underwent mierosurgery. 11 lesions lo-cated in dorsal tons were resected through midline suboccipital trans- rhomboid fnssa approach. 1 lesion located in ventrolateral pous was resected with suboceipital retrosigmoid approach. Results All the 12 cavernous hemangiomns were rosected totally and confirmed by the postoperative pathology. Clinical improvement was gained in 6 cases, no change in 3 ,aggravation of facial palsy in 1 ,death in 1. The mean follow-up time was 3 months,and Mill scan dem-onstrated good restoration of brain stem tissue with no recurrence signs of lesion. The symptoms due to the operation recovered to some extent. Conclusion The cavernous hemangioma located in brain stem can be resected safely and effectively given the selection of surgical indication and optimal surgical approach.

Objective To investigate the effects of ulinastatin on the expression of neutrophil CD_(11b) and CD_(18) during orthotopic liver transplantation(OLT).Methods Forty patients with liver diseases,ASAⅢorⅣ, undergoing OLT were randomly divided into two groups.Ulinastatin group(n=20)received intravenous infusion of ulinastatin 3?10~5 IU in 100 ml normal saline after skin incision and repeated every 4 hours thereafter.Control group received same amount of normal saline instead(n=20).Blood samples were taken immediately before skin incision,120 min after skin incision,30 min of anhepatic phase,60 min of neohepatic phase and at the end of operation for measurement of CD_(11b) and CD_(18) expression of neutrophil by flow cytometry.Results CD_(11b)/CD_(18) expression was increased significantly in control group 60 min of neohepatic phase and at the end of operation compared to the level before skin incision,but in ulinastatin group there was no significant change in CD_(11b)/CD_(18) expression during the whole procedures(P>0.05).CD_(11b)/CD_(18)expression was significantly lower 60 min of neohepatic phase and at the end of operation in ulinastatin group than in control group(P<0.01).Conclusion Ulinastatin can inhibit the increase in CD_(11b)/CD_(18)expression during OLT,and be helpful for reducing the inflammatory response.
