Objective:To investigate the protective effect of dimethylsulfoxide(DMSO) on axon degeneration.(Methods: Cultured) rat superior cervical ganglia were treated with DMSO(100%,10 ?l) per well to disconnect axons from the cell bodies.SCGs in DMSO control group were treated with a mixture of DMSO(10 ?l) and medium (2 ml) per well;in positive control group were transfected with herpes simplex virus over-expressing Wld~S protein and the cell body was eliminated;and in blank control group were treated with 10 ?l PBS.The separated axons were fixed with 4% poly formaldehyde at 0,4,8,12 and 24 h after treatment with DMSO for immunostaining with specific antibody to microtubulin.Thus,the changes of axonal structure were investigated.The axonal protein was collected and the degeneration of neurofilament was detected by Western Blotting.Results: In DMSO disconnected group,the axonal morphology and structure showed no obvious change at 12 h post disconnection,but slight degeneration was observed at 24 h post disconnection.The degradation of microtubulin was obviously slowed down and their axonal structures maintained intact 12 h later.The neurofilament could be detected 12 h after disconnection.The above changes in disconnected group were similar to those in positive control group.No obvious protective effects on axonal degeneration were observed in blank and DMSO control groups.Conclusion: Local high concentration of DMSO can delay axonal degeneration,which indicates that DMSO can be used for adjuvant treatment of neurodegenerative diseases.

Objective:To evaluate the analgesic effect of low dose ropivacaine combined with fentanyl in patient controlled epidural analgesia (PCEA) and its influence on labor and safety of mothers and their newborns. Methods:One hundred and forty healthy nullipara at term were randomly assigned to epidural analgesia or control group. The analgesia group received PCEA when their labor stage reached active period in the first stage of labor.The PCEA mode was background infusion 6 ml/h, bonus 2 ml,lockout time 10 min/each infusion. The VAS, modified Bromage scale(MBS),duration and mode of labor, postpartum hemorrhage,Apgar scores of newborns were recorded. Results:Fifteen minutes after application of PCEA,98.58% of patients felt no pains(VAS 0.057?0.48),only 4.8% showed a mild motor block(MAS 0.07?0.31).By the 60 min,all patients could move the lower limbs freely (MAS 0). The analgesia group had a significantly shorter duration of active period in the first stage of labor than that of the control group, but a significant longer duration of the second stage. In addition, the oxytocin usage was significantly more frequently in analgesia group than those in placebo group.There was no difference between the two groups in the duration of third stage, postpartum hemorrhage, Apgar scores of newborns in 1 min and 5 min, rate of cesarean section and instrumental delivery.Conclusion:Epidural analgesia with low dose ropvicaine combined with fentanyl is safe and effective, which has no influence on mothers and their infants. It could shorten the active period of labor, but may increase oxytocin usage. The ratio of cesarean section and instrumental delivery was similar between the two groups. This kind of labor analgesia is beneficial and do no harm to mothers as well as newborns.

Objective To study the effects of total saponins of Chaenomeles speciosa on release of β-hexosaminidase from rat basophilic leukemia-2H3 ( RBL-2H3 ) mast cells. Methods After rat RBL-2H3 mast cells were prepared, total saponins of Chaenomeles speciosa and the RBL-2H3 mast cells were co-cultured.The toxic effects of total saponins of Chaenomeles speciosa on mast cells were detected by MTT method, β-hexosaminidase release rate was measured by fluorescence quantitative spectrophotometric method, and cell supernatants of tumor necrosis factor-α( TNF-α) release were detected by ELISA. Results After total saponins of Chaenomeles speciosa were co-cultured with RBL-2H3 mast cells with different antigen stimulation, β-hexosaminidase release rates and the levels of TNF-α of mast cells significantly decreased compared with the control group. Conclusion Total saponins of Chaenomeles speciosa inhibit the degranulation of RBL-2H3 mast cells in a dose dependent manner, which provids basis for studying mechanism of inhibiting allergic reactions.

OBJECTIVETo evaluate preliminarily the efficacy on functional constipation treated with electroacupuncture of different acupoint prescriptions.

METHODSOne hundred and four patients were randomized into a front-mu and back-shu points group (19 cases), a he-sea points group (34 cases), a he-sea, front-mu and back-shu points group (26 cases) and a western medication control group (25 cases). In the front-mu and back-shu points group, electroacupuncture was applied at bilateral Tianshu (ST 25) and Dachangshu (BL 25). In the he-sea points group, electroacupuncture was applied at bilateral Quchi (LI 11) and Shangjuxu (ST 37). In the he-sea, front-mu and back-shu points group, electroacupuncture was applied at unilateral Tianshu (ST 25), Dachangshu (BL 25), Quchi (LI 11) and Shangjuxu (ST 37). In the three groups above, the treatment was given 5 times a week in the first two weeks and 3 times a week in the next two weeks. In the western medication control group, mosapride citrate tablets were prescribed for oral administration, 1 table (5 mg) each time, 3 times a day, continuously for 4 weeks. The period of research was 9 weeks, including 1 week for baseline evaluation, 4 weeks for treatment and 4 weeks for follow-up. The weekly defecation frequency was taken as primary index, while the defecation difficulty and life quality score were taken as the secondary indices for the efficacy evaluation after treatment and in follow-up.

RESULTSAccording to the intention-to-treat (ITT) analytic principle, 104 cases were all enrolled in the final analysis. (1) After treatment, the weekly frequency of defecation was all increased significantly in the four groups (P < 0.05, P < 0.01). The efficacy of the three electroacupuncture groups was similar to that of western medication control group (P > 0.05). In follow-up, the increasing effect on the weekly frequency of defecation was maintained in the he-sea points group (P < 0.01), superior to the front-mu and back-shu points group and the western medication control group (P < 0.05, P < 0.01); the weekly frequency of defecation was not improved in the rest three groups (P > 0.05). (2) After treatment, defecation difficulty was relieved in the he-sea points group, the he-sea, front-mu and back-shu points group and the western medication control group (P < 0.05, P < 0.01). In follow-up, the improvements were still significant in the he-sea points group and the he-sea, front-mu and back-shu points group (both P < 0.01). (3) After treatment, the life quality score was significantly improved in the patients of the he-sea points group (P < 0.05). The difference was not significant in the rest three groups as compared with that before treatment (all P > 0.05).

CONCLUSIONThe weekly frequency of defecation is increased effectively after treatment in the three electroacupuncture groups and the efficacy is similar to mosapride citrate tablets. The bilateral Quchi (LI 11) and Shangjuxu (ST 37) in he-sea acupoints increase significantly the weekly frequency of defecation, relieve defecation difficulty and improve life quality. Acupuncture efficacy is sustained for 4 weeks. This acupoints prescription is the best in the treatment of functional constipation.

Objective In order to investigate the relationship between hearing loss and diabetic peripheral neuropathy( DPN ) via comparing the pure tone thresholds and vibration perception threshold(VPT) in type 2 diabetic patients and control person without diabetes. Methods 173 subjects including 138 type 2 diabetic patients(DM)and 35 non-diabetes controls were examined for VPT and hearing threshold. Nerve conducting velocity ( NCV )including sensory nerve conducting velocity( SCV )and motorial nerve conducting velocity( MCV )of diabetic patients were determined. The participants were divided into three groups: control group (n = 35 ), DM group without peripheral neuropathy( non-PN group, n = 74 ), and DM group complicated with peripheral neuropathy (PN group,n = 64 ). The clinical characteristics, biochemical parameters , the incidence of sensorineural hearing loss ( SNHL),pure tone threshold, and VPT were compared among three groups. At last, the relationship between hearing thresholds and NCV were analyzed. Results The incidence of hearing impairment of sensorineural type was 29.69% in PN group, which was significantly higher than that of non-PN group( 17.57% )and control group( 17. 14% ). There was significant differences in age, duration of diabetes, glycolated hemoglobin (HbA1c), glycolated serum albumin ( GA), Fasting blood glucose( FPG), 2h postprandial blood glucose( PPG), VPT, and hearing threshold among the three groups( all P＜0. 05 ). The value of hearing threshold increased significantly( all P＜0. 05 ) in 3 VPT subgroups with VPT≤ 15 V, VPT 16-25 V, and VPT ＞25 V. The Spearman correlation analysis showed median NCV was negatively correlated with hearing threshold on 1.00, 2.00, 4. 00, and 8. 00 kHz ( All P ＜ 0. 05 ). The logistic regression analysis indicated that the age( regression coefficient =0. 088, P＜0. 01 ) was the independent risk factor of SNHL, median nerve MCV ( regression coefficient = -0. 135, P = 0. 046 ) was the important influencing factor of SNHL. Conclusion Diabetic patients are more likely to suffer from impaired middle-frequency and high-frequency hearing, DPN in patients is often complicated with hearing impairment. Age and median nerve MCV were major risk factors of SNHL in diabetic patients.

In order to investigate the hygienic characteristic of anti-immersion trousers, ten male soldiers dressed in the trousers or in camouflage trousers were subjected to exercise test and sedentary test respectively at room temperature of 17?2℃. In the test, eleven parameters such as core temperature, skin temperature, heat flow and so on were observed. The results indicated that in sedentary tests, the low limb heat flow of the subjects dressed in anti-immersion trousers was larger than that dressed in camouflage trousers; the heat insulation value of anti-immersion trousers was smaller than that of camouflage trousers; and for the other parameters, there was no evident difference between the two group. It suggested that when used on land, hygiene characteristic and effect on body heat balance of the anti-immersion trousers were similar to those of camouflage trousers.
