AIM: To compare the effects between topiramate and slow-release sodium valproate in treating refractory epilepsy. 　METHODS: Topiramate group of 39 patients (M 21, F 18; age 28 a± s 20 a) was compared with sodium valproate group of 41 patients (M 22, F 19; age 27 a±17 a) in antiepileptic effect of refractory epilepsy. Adult's and children's dosages of topiramate were increased gradually about 200 mg*d-1 and 4 mg*kg*d-1 respectively during about 2 mo, po, bid, for 6 mo as a course. Adult's dosage of slow-release sodium valproate was 0.5-1 g*d-1, and children's was increased gradually to total dosage: 15-30 mg*kg*d-1, po, qd or bid (morning or morning and noon), for 6 mo as a course. Effects were analysed between these two drugs after treatment 4 and 6 mo.　RESULTS： Simple and complex partial seizures with or without secondary generalized seizure, in topiramate group were much more improved than these in sodium valproate group 6 mo after treatment. Four patients of topiramate group appeared temporary adverse reactions of central nervous system, such as tiredness, sleepiness and distraction, but one patient of sodium valproate group had severer decreased function of bone marrow.　CONCLUSION: Topiramate is one of effective antiepileptic drugs and superior to slow-release sodium valproate. There are the apparent absence of any effects of topiramate on the bone marrow and on indexes of liver and kidney.

Objective To determine the prevalence of latex glove(LG)-induced type Ⅳ hypersensitivity in clinical nurses. Methods 100 clinical nurses were selected,among whom 69 nurses were set as the latex glove hypersensitivity group,and the other 31 nurses did not show hypersensitivity to latex glove (the control group).The two groupe underwent a patch testing with a modified European standard series of allergens supplied by Chemotechnique Diagnostics.The positive allergens were compared between the two groups. Results The positive rate of patch testing in patients of the latex glove hypersensitivity group was superior to that in the control group (73.9％ vs 25.8％).Cobalt chloride and potassium dichromate were the most common allergens in both groups,while only formaldehyde and para-phenylenediamine were more susceptible in the latex glove hypersensitivity group compared with that in the control group.26.1％ of the latex glove hypersensitivity group was responsive to rubber additives,but in the control group the results were negative.Conclusions The hand dermatitis of female nurses with LG allergy is mainly caused by exposure to daily necessities.The prevalence of LG-induced type Ⅳ hypenensitivity is relatively high in clinical murses.

AIM: To down-regulate expression of c-myc through antisense therapy and to investigate its effect on the sensitivity of osteosarcoma MG-63 cells to cisplatin-induced apoptosis. METHODS: The recombinant adenovirus (Ad-Asc-myc) encoding antisense c-myc fragment was constructed and transfected into osteosarcoma MG-63 cells in vitro in order to down-regulate the expression of c-myc, and the change in the sensitivity to cisplatin-induced apoptosis was observed. MTT, Western blot, RT-PCR, flow cytometry (FCM) and electron microscope were used to evaluate tumor cell proliferation in vitro, genes expression related to apoptosis regulation and effects on the sensitivity of osteosarcoma MG-63 cells to cisplatin-induced apoptosis. RESULTS: Ad-Asc-myc down-regulated the expression of c-myc protein after transfected MG-63 cells for 48 h, combined with the treatment of 2.0 mg/L cisplatin for 2 h inhibited tumor cell proliferation in vitro by 38.0%. RT-PCR revealed that Ad-Asc-myc down-regulated the expression of Bcl-2 and up-regulated the expression of Bax. No appreciable change was observed in the expression of E_2F-1. FCM showed that Ad-Asc-myc induced apoptosis in intransfected cells, and rendered it more sensitive to cisplatin. CONCLUSION: Antisense c-myc is able per se to induce apoptosis and sensitize osteosarcoma cells to cisplatin-induced apoptosis.

Objective To explore the effects of modified herringbone-Trendelenburg position during gynecological laparoscopic operation of the elderly. Methods A total of 60 elderly patients undergoing gynecological laparoscopic operation under general anesthesia were recruited and assigned to the observation group (30 cases) and control group (30 cases) by random digits table method with 30 cases each according to admitting time;Patients in the control group were placed in conventional Trendelenburg position, while the patients in the observation group were positioned in modified herringbone-Trendelenburg position .Intraocular pressure (IOP) were measured in the patients at anesthesia induction (T1),5 minutes after general anesthesia in supine position (T2) , and 5 minutes after pneumoperitoneum while in the operation position (T3) , every 30 minutes (times 4 to 11), while supine at the end of pneumoperitoneum (time 12) and before awakening (time 13);Patients were followed up at 24 h and 48 h after surgery, researcher investigate and record the scores of the Operation Position Comfort Questionnaire, the situation of the pain in the shoulder and postoperative complications of the lower limbs. Results There was no statistically significant difference (t=-1.098,-0.772,-0.656, P>0.05) of the IOP at T1, T2, T13. The IOP in the observation group had statistically significant difference compared with the control group at T3 to T12 (t=6.523-19.866, P<0.01). The incidence rate of the postoperative complications of the lower limbs in the observation group was 6.7%(2/30) lower than 26.7%(8/30) of the control group (χ2=4.320, P<0.05) and the VAS scores of the patients in the two groups was statistically significant (t=2.471, P<0.05). The incidence rate of the postoperative shoulder pain in the observation group was 10.0%(3/30) lower than 43.3%(13/30) of the control group (χ2=8.523, P<0.01), and the Visual Analogue Scale scores of the patients in the two groups was statistically significant (t=3.575, P<0.05).The scores of the Operation Position Comfort Questionnaire in the observation group was higher than the control group (t=-2.319, P<0.05). Conclusions Modified herringbone- Trendelenburg position can reduce the elevation of intraocular pressure in elderly patients without affecting the operation ,and effectively improve the comfort of the operation position of the patients, reduce the incidence rate of the shoulder pain and postoperative complications of the lower limbs, is conducive to the operation safety of elderly patients.

ObjectiveIn order to study the effect of three-month rehabilitation on motor function in hemiplegics after stroke. Methods125 patients were randomly divided into two groups, rehabilitation group (72 cases)and control group(53 cases).Patients in the rehabilitation group were given clinical treatment,electric stimulation therapy(EST) and regularly physical therapy, while those in control group were given clinical treatment and unguided self-training, and the evaluation was done in pre-treatment and post-three-month respectively. Motor function was assessed in Fugl-Meyer Assessment(FMA).ResultsMotor scores in each group had a more significant difference(P<0.001)before and after treatment, the process of scores in the rehabilitation group was obviously superior to that in the control group(P<0.001). Conclusions Rehabilitation training on hemiplegics after stroke may obviously improve motor function, depressing the disability and increasing the living quality.

Objective To compare the thin-section CT findings of pulmonary candidiasis,aspergillosis and eryptococcosis wim histopathology in immunoeomprimised rabbits and impmve the diagnostic accuracy of fungus infection. Methods Heathy New Zealand white rabbits were used for immunoeompromised animal models.Thin-section CT scan was performed before and 2,4,6,8,10,12,14 d after inoculation.The pattern and distribution of the pulmonary abnormalities were retrospectively assessed by two thomeic radiologists and compared with histopathology.The granulocyte count was compared before and after administration of immunosuppressive agents.The pmred t test,chi square test and the Fisher's exact test were used for the statistics.Results Fourteen rabbits had candidiasis.16 rabbits had cryptocoecosis,15 rabbits had aspergillosis.The granulocyte counts before and after administration of immunosuppressive agents were(2.91±0.92)and(0.35±0.19)×109/L respectively in eandidiasis group,there was a significant difference(t=12.484,P＜0.05);(2.51±0.82)and(0.76±0.71)×109/L in aspergillosis group,there was a significant difference(t=5.792,P＜0.05);(2.10±0.65)and (0.48±0.22)×109/L in cryptococcosis group,there was a significant difference(t=8.199,P＜0.05).The onaet time of infections on CT were not significantly different in three groups (P＞0.05).Ground glass opacity (GGO) and consolidation were the two most colnlnon findings in immunocompromised rabbits with three fungus infections,areas of GGO was correlated with the congestion,hemorrhage,inflammatory cell infiltration and interstitial hyperplasia in pathology. Consolidation was correlated with the severe congestion,hemorrhage, inflammatory cell infiltration, interstitial hyperplasia, necrosis and vascular embolism in pathology. Conclusion GGO and consolidation are the two most common findings of fungus infections in immunocompromised animal models and thin-section CT findings can reflect the pathological changes.
