Objective The aim of this study was to investigate the effects of hesperidin ( HDN) on antioxidant ac-tivity in mice.Methods HDN scavenging free radicals was detected by spectrophotometry, inhibition of mitochondrial swelling was detected by pyrogallol autoxidation, and erythrocyte hemolysis was detected by Fe2+phenanthroline.The mice were fed with HDN at different concentrations (0, 80, 160, 320 mg/kg) by gastric gavage for 12 days.ELISA and spec-trophotometric methods were used to assay the amount of MDA in mouse liver and kidney tissues and the activity of antioxi-dant enzymes ( SOD, CAT, GSH-PX) , and the antioxidant enzyme gene mRNA expression was analyzed by RT-PCR.Re-sults Compared with the control group, the radical (· OH, O2 -· , DPPH· ) clearance rate was significantly increased in the HDN groups.There was a significant decrease of oxidative hemolysis of erythrocytes and mitochondrial swelling in vitro. MDA content in the mouse liver and kidney tissues and serum showed a decrease, and the activity of antioxidant enzymes ( SOD, CAT, GSH-PX) in the HDN group was significantly higher than that in the control group.There was an up-regula-tion of mRNA expression of antioxidant enzyme in mouse liver and kidney tissues.Conclusions The results showed that HDN can eliminate free radicals, reduce cell oxidative damage caused by free radicals, inhibit superoxide production, up-regulate antioxidant enzyme gene expression and enhance their enzyme activity, thus showing a good antioxidant effect.

Objective To investigate the protective effect and associated mechanism of PNS in spinal cord hemisection injury.Methods fifty-five adult SD rats were randomly divided into three groups,sham group(n =5),spinal cord injury group(n =25),PNS group(n =25).The rats were evaluated in behavioral test with BBB score,pathology and immunohistochemistry at 1 d,3d,7d,14d,21d after the procedures.Results Motor recovery was significantly better in PNS group than the spinal cord injury group at 3d,7d,14d and 21d.Nissl staining showed less neuron necrosis and more integrated neural cells in morphology.cPLA2 expression was inhabited in PNS group,and less number of positive cells were found in the group.Conclusion PNS can inhibit the expression of cPLA2 after spinal cord injury,which may be one of the mechanisms of its effect on promoting motor recovery.

Objective To investigate the levels of monocyte chemoattractant protein 4 (MCP-4), macrophage derived chemokine (MDC) and cysteinyl leukotrienes (CysLTs) in serum of children with mycoplasma pneumonia (MP). Methods Serum levels of MCP-4, MDC and CysLTs measured by enzyme linked immunosorbent assay were analyzed in 60 children with MP including 36 children with wheezing (MP wheezing group) and 24 children without wheezing (MP non-wheezing group), 30 children with pneumonia but not infected with mycoplasma pneumonia (NMP group), 35 children with acute asthma exacerbation (asthma group), and 25 health children (control group). Results Serum levels of MCP-4, CysLTs and MDC were found markedly elevated in asthma group. The serum levels of MCP-4 and MDC showed signiifcant difference between each of the groups (all P<0.01) except that between non-wheezing group and NMP group (P>0.05). As for serum level of CysLTs, no signiifcant differences were found between asthma group and MP wheezing group, NMP group and MP-non-wheezing group (all P>0.05). The serum levels of MCP-4, MCD and CysLTs in children with MP were positively correlated with one another. Conclusions MCP-4, MDC and CysLTs play important roles in pathogenesis of MP and are the major causes of wheezing in MP.

Objective To evaluate the efficacy of interventional therapy for advanced pancreatic carcinoma. Methods 33 cases of advanced pancreatic carcinoma accepted interventional therapy from April 2005 were retrospectively analyzed. All patients were unoperable and accepted one or more times of celiac and superior mesenteric arterial chemotheraputics perfusion with dosage of 2:1. The embolization was further introduced with the addition of liver invasion. The repetition interval was kept at 6 weeks with no severe complications. Results The one with follow-up CT imagings showed obvious decrease of the lesion size, together with release or disappearance of the sensation of abdominal pain and abdominal distention. The life span prolonged with average survival of 13 months, including the longest of 22 months and the life quality improved. Conclusions The interventional therapy could be the first method of choice in the management of advanced pancreatic carcinoma.

Objective To investigate the protective effect and cytosolic phospholipase A2 (cPLA2) associated mechanism of panax notoginseng saponins (PNS) in spinal cord hemisection injured rats. Methods 55 adult Sprague-Dawley rats were randomly divided into three groups: sham group (n=5), spinal cord injury group (n=25) and PNS group (n=25). The rats were evaluated with BBB score, pathology and immunohistochemistry 1 d, 3 d, 7 d, 14 d and 21 d after intervention. Results Compared to the spinal cord injury group, motor recovery was significantly better in PNS group 3 d, 7 d, 14 d and 21 d after intervention (P<0.05). Nissl staining showed less neuron necrosis and more integrated neural cells in morphology in PNS group 7 d, 14 d and 21 d after intervention. Cytosolic phospholipase A2 (cPLA2) expression was inhabited, and less number of positive cells were found in PNS group 7 d, 14 d and 21 d after intervention. Conclusion PNS can inhibit the expression of cPLA2 after spinal cord injury, which may be one of the mechanisms of its effect on promoting motor recovery.

The clinical application of arthroscopic minimally invasive treatment of shoulder joint disease technology has become a routine,and it has been widely carried out around the world.Compared with the traditional open surgery,it only needs to establish a few channels in the shoulder and then the diagnosis and treatment of the structure under the acromion and glenoid joint internal lesions can be completed through the arthroscopic technique under direct vision,of course,including local collection of pathological specimens.Shoulder arthroscopic surgery has the advantages of simple operation technique,small economic burden of patients,small tissue trauma,quick recovery and high accuracy of disease diagnosis.At present,there are two main options for shoulder arthroscopy:the beach chair position (BCP) and the lateral decubitus position (LDP).The choice of surgical position for surgeons is closely related to the intraoperative operation,the risk of complications,the efficacy of surgery,and the cost of setting the posture.Shoulder arthroscopy of these two positions have their own advantages and disadvantages:in the BCP,the surgeon gets a better anatomical operation experience,if necessary,can be converted into open surgery at any time.Without continuous traction,upper limb nerve and vascular damage caused by traction can be avoid.But the incidence of cerebral ischemic events in patients may increase in the BCP.There is also possibility of the nerve damage of the pillow small nerve,great auricular nerve,lateral femoral cutaneous nerve and other nerves.In theory the risk of air embolism in the patients will increase in the BCP,and the cost of setting the position is also higher than the LDP.While in the LDP due to the patient's forearm continuous traction,the surgeon can get a more extensive operating space,and the occurrence of cerebral ischemic events is very rare.In the treatment of anterior shoulder instability after shoulder arthroscopic surgery,there is a lower recurrence rate in the LDP.The cost of setting the position is also significantly lower than the BCP.Of course,the disadvantages of the LDP is also obvious.In the LDP,the brachial plexus and other nerves or vascular injury may increase due to the continuous traction of the forearm.Meanwhile sustained traction in the LDP is also a risk factor for thrombosis,and so on.Therefore,there is still a debate about the optimal location of the shoulder arthroscopy.Many clinicians choose shoulder arthroscopic position based on their own experience and habits.

OBJECTIVE To discover diversity of X gene sequences of hepatitis B virus isolates in hepatitis B induced liver cirrhosis patients and HBV carriers.METHODS DNA fragment including X gene sequences of hepatitis B virus was amplified,sequencing PCR products was preformed.The PCR products of three liver cirrhosis patients and three HBV symptomless carriers were cloned into pGEMT Easy vectors.Positive clones with target sequences were selected out for sequencing.Sequence comparison was made to find the identity.RESULTS A comparison of T1762/A1764,G1719T,T1727G/A,G1730C and T1753C mutations in a core promoter between the liver cirrhosis patients and the HBV carriers showed that the HBV isolates from the former had higher frequencies of mutation than the latter.The X promoter region of the HBV isolates from the liver cirrhosis patients showed higher frequencies of mutation than the isolates from the HBV carriers.Additionally,the homology between clones of X gene from one individual with liver cirrhosis averages 91.3-99.7%,that of HBV carriers averages 96-100%.CONCLUSIONS The core and X promoter region of the HBV isolates from the liver cirrhosis patients show the higher frequencies of mutation than the isolates from the HBV carriers.There are HBV quasispecies which possess great variation in the liver cirrhosis patients.
