BACKGROUND: Activated by Ca2+, phospholipase A2 will aggravate the influx of Ca2+ or the release of intracellular Ca2+, and then forms a vicious circle, which results in a continuous increase in free calcium level and leads to server injury in neural cells.OBJECTIVE: To discuss the protective effects of nimodipine on acute ischemic brain injury caused by activation of phospholipase A2.DESIGN: A completely randomized controlled trial.SETTING: Intensive Care Unit (ICU) of Children's Hospital, Chongqing Medical University.MATERIALS: From January 2001 to October 2003, it was completed at the ICU of Children' s Hospital, Chongqing Medical University. Thirty male rats were selected and divided into sham operation group, ischemia group and nimodipine treated group randomly, with 10 rats in each group.METHODS: In sham operation group, the right common carotid artery was identified by blunt dissection without ligation under anesthesia in rats. In ischemia group, at 30 minutes before cerebral ischemia, 2 mL saline was injected intraperitoneally. In nimodipine treated group, at 30 minutes before cerebral ischemia, 0.2 g/L nimodipine (2 mg/kg) was injected intraperitoneally. In all the three groups, the duration between ischemia and decollation was 120 minutes. Rats were decollated under anesthesia and their brains were taken out to assess the activity of phospholipase A2, the free calcium level in brain cells, the brain water content and the changes in mRNA levels of type Ⅱ phospholipase A2 (secretive phospholipase A2) and type Ⅳ phospholipase A2 (cytoplasmic phospholipase A2) in brain tissue.pholipase A2) and type Ⅱ phospholipase A2 (cytoplasmic phospholipase A2)in brain tissue were measured in rats in all the groups.pholipsse A2 in brain tissue: In ischemia group and nimodipine treated group, the activity of phospholipase A2 were higher than that in sham operation group [(57.8 ±7.2),(42.5±6.1), (17.1±5.3)%, P＜ 0.05-0.01], and it was a litter lower in nimodipine brain cells: It was higher in nimodipine treated group and ischemia group than that in sham operation group [(775.8±105.5), (497.2±45.9), (103.8±10.3) μmol/L,P ＜ 0.05-0.01], and it was lower in nimodipine group than in ischemia group (P ＜ 0.01).that in sham operation group [(82.9±0.5), (80.0±1.1), (72.1±0.01)%, P ＜ 0.05-0.01], and it was lower in nimodipine treated group than that in ischemia group (Ppase A2 could be detected in brain tissue. And the mRNA level of type Ⅱ phospholipase A2 in brain tissue was very low. At 120 minutes after ischemia, mRNA of type Ⅱ phospholipase A2 was detectable and the expression of type Ⅱ phospholipase A2 was increased. Compared to ischemia group, the expression of type Ⅱ phospholipase A2 was not decreased in nimodipine treated group while the expression of type Ⅱ phospholipase A2 was decreased.CONCLUSION: Nimodipine is capable of decreasing the free calcium level in brain cells, the activity of phospholipase A2 in brain tissue and the brain water content after ischemia. However, it cannot significantly inhibit the expressions of type Ⅱ phospholipase A2 and type Ⅱ phospholipase A2 after cerebral ischemia.

Objective To analyze the clinical effects of individualized comprehensive physiotherapy interventions for temporomandibular disorders (TMD).Methods Data of 307 patients with TMD treated between April 2011 and March 2012 in the authors' department were collected and reviewed.All the patients were treated with individualized comprehensive physiotherapy approach based on the patient's category in research diagnostic criteria for TMD (RDC/TMD),such as patient education,ultrashort-wave diathermy,ultrasound therapy,soft tissue massage,joint mobilization and stabilization exercise.The treatment was administered for 3 weeks.The baseline and endpoint outcome assessment measures were maximum active mouth opening (mm),visual analogue scale (VAS) score and joint clicking (100％ before treatment).Results At the end of treatment,the patient's maximum active mouth opening [(36.95 ± 6.59) mm],VAS score (1.21 ± 0.62) and joint clicking [(29 ± 17) ％] improved significantly (P ＜ 0.05) compared to baseline.Conclusions Individualized comprehensive physiotherapy interventions can improve symptoms of TMD,such as joint clicking,pain,limited mouth opening.

BACKGROUND: Free radicals are produced during ischemia, which can strengthen activity of lipid peroxidation; induce lesion of cell and cellular barrier, result in necrosis or apoptosis of neurons; and aggravate edema of ischemic cerebral tissue.OBJECTIVE: To observe the effects of polydatin (PD) on free radicals, lipid peroxidation, water contents and pathological morphology of brain tissue in rats with focal cerebral ischemia so as to explore its protective mechanisms.DESIGN: A randomized controlled trial.SETTING: Intensive Care Unit, Second Affiliated Hospital, Chongqing University of Medical Sciences; Pediatric Research Institute, Children's Hospital Chongqing University of Medical Sciences.MATERIALS: The experiment was carried out at the Pediatrics Medicine Institute of Chongqing Medical University from October 2001 to July 2002.Totally 48 healthy adult male Wistar rats were divided into 3 groups randomly,with 16 in each group. Group Ⅰ was sham-operated group: rats were anaesthetized, the right common carotid arteries were separated instead of being occluded. Group Ⅱ was ischemia group: to establish the right middle cerebral artery occlusion model of rats. Group Ⅲ was PD pretreatment group: polydatin (6 g/L, 12 mg/kg) were intravenously administrated 30 minutes before the onset of ischemia. Saline substituted for PD, besides, were intravenously administrated with the same way and dosage on Group Ⅰ, Group Ⅱ and Group Ⅲ.The rats were decapitated and the brains were immediately removed after cerebral ischemia 2 hours. In each group, 8 rats were chosen to be determined water contents of brain tissue, the other 8 rats were chosen to be determined levels of lipid peroxidation and free radicals in brain tissue.METHODS: According to the formula which was: wet weight-dry weight/wet weight×100%, water content of cerebral tissue was assayed. Superior liquid was taken to assay MDA with spectrophotometer thiobarbituric acid method (TBA) method, SOD activity assayed by xanthiue oxidase enzyme method, the activities of GSH-Px, CAT and NOS determined by colorimetry,the amount of protein determined by the method of Lowry. All the procedures were carried out strictly according to the instruction.malonaldehyde (MDA) and activities of superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), catalase (CAT) and nitric oxide synthase chemia, contents of SOD, GSH-Px and CAT in cerebral tissue of PD group were obviously higher than those of ichemia model group [(226.43±8.69),(193.37±11.14) NU/mg; (244.38±12.34), (211.71±16.50) μkat/g; (59.85±9.67),water in cerebral tissue of PD group were obviously lower than those of ichemia model group [(6.38±0.54), (8.63±0.78) μmol/g; (78.72±0.43)%,tivity in ischemic tissue but the results were similar to that in ischemia model group [(12.00±1.00), (12.84±1.17) μkat/g, P ＞ 0.05] in brain tissue.ed that PD alleviated the ischemia edema of cerebral ischemia.CONCLUSION: PD can alleviate the reaction of lipid overoxidation, improve the activities of antioxidant-enxymes, reduce ischemia brain edema,protect the function of cell member, bring down the damage to ischemia neurons. It shows that PD has significant cerebral protective role on focal ischemia brain damage.

BACKGROUND: Kidney ischemia-reperfusion injury often combines with acute kidney and lung injury. The expression of cutin cel growth factor receptor (KGFR) and alpha sodiumchannel protein (α-ENaC) in kidney and lung after ischemia-reperfusion injury and the protective effect of α-melanocyte require further observation and research. OBJECTIVE:To explore the therapeutic effect of α-melanocyte on the expressions of KGFR and α-ENaC in rat models of ischemia-reperfusion injury. METHODS:A total of 30 healthy male Sprague-Dawley rats were randomly divided into control group, ischemia-reperfusion group and α-MSH group. Models of renal ischemia-reperfusion injury were established by 30-minute ligation of renal artery in the ischemia-reperfusion and α-melanocyte groups. Rats in the control group were only used to expose the renal artery, no ligation. Rats in the α-melanocyte group were intraperitonealy injected with α-melanocyte (0.25 mg/kg) at 30 minutes before model establishment. Rats in the ischemia-reperfusion group were injected with 4 mL of physiological saline. RESULTS AND CONCLUSION: Compared with control group, water content of kidney and lung increased significantly in rats of ischemia-reperfusion group and a-MSH group, while the levels of KGFR and α-ENaC of kidney and lung in rats were lower (P < 0.05). Compared with the ischemia-reperfusion group, water content of kidney and lung in rats of a-MSH group decreased significantly, while the levels of KGFR and α-ENaC of kidney and lung increased gradualy (P < 0.05). Moreover, edema was significantly lessened in the rat kidney and lung. Results confirmed that after renal ischemia-reperfusion injury, KGFR and α-ENaC expression was consistent to the kidney and lung injury. α-MSH could increase the protein and mRNA expression of KGFR and α-ENaC in kidney and lung of rats, reduce the kidney and lung injury, and exert a certain protective effect.

BACKGROUND:The third molar extraction may lead to different degrees of soft tissue damage. Ultrasound and ultrashort waves belong to hyperthermia, which can increase tissue temperature and improve the therapeutic efficacy of soft tissue stretch. OBJECTIVE:To observe the effects of soft tissue stretch combined with ultrasound and ultrashort wave therapy for patients who were recently diagnosed with trismus and pain folowing third molar removal. METHODS:Sixteen patients with trismus and pain after third molar removal were randomly divided into two groups: patients in stretch group received soft tissue stretch with ultrasound and ultrashort wave therapy, while those in control group received only ultrasound and ultrashort wave therapy. Patients received the treatment five times per week, totaly for 2 weeks. RESULTS AND CONCLUSION:It was found that after treatment pain was significantly reduced at the temporomandibular joint, and the range of maximum active mouth opening increased significantly. The improvement in mouth opening and temporomandibular joint function was better in the stretch group than the control group. These findings indicate that ultrasound and ultrashort wave therapy can improve symptoms of trismus and pain folowing third molar removal, and the combination of ultrasound and ultrashort wave therapy and soft tissue stretch therapy can achieve more effective results.

Background and purpose: As the most common tracer used for PET/CT to detect malignant tumors. ~(18)F-fluorodeoxyglucose (~(18)F-FDG) can reflect the metabolism of glucose. However, there exists physiologic uptake in the intestinal tract of healthy people. Because ileocecal foci is predilection site of malignant tumors and inflammatory disease, the purpose of this study was to investigate the discrimination of PET/CT detection of incidental ileocecal high FDG uptake. Methods: We retrospectively analyzed 28 unexpected ileocecal focal uptake of ~(18)F-FDG localized by PET/CT, and then semi-quantitatively analyzed the extent of radioactive uptake in ileocecal foci. After PET/CT, the etiology of the findings was confirmed histologically by surgery, endoscopic or by long-term follow-up. All the data were assessed for statistical significance using one-way ANOVA. Results: In all the ileocecal foci, there were 14(50%) physiologic FDG uptake, 8 (28.6%) benign diseases and 6 (21.4%) malignant tumor. Maximal standardized uptake value was 5.2±1.6 in physiologic uptake, 6.8±4.1 in benign lesions and 12.8±5.5 in malignant lesions. There was statistically significant difference between malignant tumors and the other 2 groups. According to ROC analysis, when SUN_(max) was 6.75, the sensitivity and specificity of ileocecal malignant tumor were 100% and 86.4%, respectively. Conclusion: The significant value of discrimination between benign and malignant lesions of ileocecal focal FDG uptake by PET/CT was affirmative. It is very important to recognize physiologic uptake of ileocecal conjunction in the interpretation of image. Semi-quantitative analyze was not helpful to identify benign lesions from physiologic uptake.
