Objective To observe the clinical effect of electroacupuncture and Shenmai injection combined with conventional western therapy as treatments for the sudden deafness.Methods A total of 186 patients with sudden deafness were randomly divided into two groups. Each group included 93 patients. The control group was treated with the pipe-expanding and anti-inflammatory, but the treatment group was treated with electroacupuncture and Shenmai injection based on the control group. Both groups were treated for 11 days.Before and after treatments, the regional cerebral blood flow (rCBF) was detected. The MADSEN was used to detect ocular vestibular evoked myogenic potential (oVEMP), including N1-Pl amplitude, N 1-Pl incubation period, N1-Pl wave duration and extraction rate of oVEMP.Results The recovery rate of control group was 63.4% (59/93) and total effective rate was 90.3% (84/93), which was 88.6% (75/93) and 97.8% (91/93) in combined treatment group, and there was significant difference between the 2 groups (χ2=5.923,P<0.05). After 11 days of treatment, the Tinnitus (17.2%vs. 30.1%,χ2=7.152), vertigo and survival rate (15.1%vs. 21.5%, χ2=6.023) in combined treatment group showed significantly lower than those in the control group (P<0.05). The threshold (39.59 ± 5.36 dBHLvs. 45.85 ± 5.08 dBHL,t=2.903) in combined treatment group showed significantly lower than those in the control group (P=0.034). The N1 amplitude (10.62 ± 0.84μVvs. 7.14 ± 0.59μV;t=3.259,P=0.017), P1 amplitude (11.79 ± 0.91μVvs. 9.90 ± 0.82μV;t=2.871,P=0.037), extraction rate of oVEMP (95.7%vs. 81.7%;χ2=7.963,P=0.012) in combined treatment group showed significantly higher than those in the control group. The N1 incubation period (7.86 ± 0.82 msvs. 9.78 ± 1.24 ms;t=3.729,P=0.009) and Pl incubation period (6.57 ± 0.77 msvs. 9.39 ± 1.15 ms;t=3.064,P=0.025) in combined treatment group showed significantly lower than those in the control group.Conclusions The Electroacupuncture and Shenmai injection combined with conventional western therapy could improve blood circulation produce a synergistic therapeutic effect on damaged tissue, improve cochlear hair cells and vestibular nerve regeneration, and repaire the functions.

Objective To investigate the volume kinetics of 6% hydroxyethyl starch 130/0.4 in healthy volunteers.Methods Seven healthy volunteers aged 18-32 yr weighing 46-84 kg were selected in this study. 6% hydroxyethyl starch 130/0.4 30 ml/kg was infused over 60 min. Volume kinetics analysis of 6% hydroxyethyl starch 130/0.4 was performed with Matlab 6.0 software, compartment model was determined by F test.Results One-compartment model parameters: basic clearance, clearance and distribution volume of one-compartment model were (3.5 ± 1.3) ml/min,(19± 11) ml/min and (5746 ± 1371) ml respectively. Two-compartment model parameters: clearance, K1, the volume of central compartment, the volume of peripheral compartment, distribution volume of two-compartment model were (63 ±29) ml/min,(11 ±4) ml/min, (1551 ± 995) ml, (908 ±398) ml,(2460 ± 1332) ml respectively. There was no difference between the distribution volume of one-compartment model and blood volume of healthy volunteers ( P ＞ 0.05) .The distribution of infused 6% hydroxyethyl starch 130/0.4 was accordant with one-compartment model (F value was 3.81, P ＞ 0.05)and 4 h clearance was (75 ± 10)% .Conclusion The distribution of infused 6% hydroxyethyl starch 130/0.4 for volume expansion is accordant with one-compartment model, and the effective duration of plasma volume expansion is 4 h.

ObjectiveTo investigate the effect of dexmedetomidine pretreatment on focal cerebral ischemia-reperfusion(I/R) injury in rats.MethodsOne hundred male SD rats weighing 290-310 g were randomly divided into 5 groups(n =20 each):sham operation group(group SH) ; focal cerebral I/R group; focal cerebral I/R + dexmedetomidine 100 μg/kg(group L); focal cerebral I/R+ dexmedetomidine 200 μg/kg (group M) and focal cerebral I/R + dexmedetomidine 400 μg/kg(group H).Focal cerebral I/R was produced by occlusion of middle cerebral artery for 60 min followed by 24 h of reperfusion.Dexmedetomidine 100,200 and 400 μg/kg were injected intraperitoneally 15 min before ischemia in groups L,M and H respectively.While equal volume of normal saline was injected intraperitoneally in group SH.Neurologic function was assessed and scored at 24 h of reperfusion.Then the animals were sacrificed and brains were removed for determination of cerebral infarct volume and microscopic examination.The expression of heat shock protein 70(HSP70) and activity of Na+ -K + -ATPase in ischemic cortex and activity of SOD and concentration of cortisol in plasma were determinationed at 24 h of reperfusion.ResultsCompared with group SH,neurologic deficit scores and plasma concentration of cortisol were significantly increased,activities of SOD and Na+ -K+ -ATPase decreased and expression of HSP70 was up-regulated in groups I/R,L,M and H( P ＜ 0.05).Compared with group I/R,neurologic deficit scores and plasma concentration of cortisol were significantly decreased,activities of SOD and Na+ -K+ -ATPase increased and expression of HSP70 was up-regulated in a dose-dependent manner ( P ＜ 0.05),and the pathological change was reduced in a dose-dependent manner in groups L,M and H.ConclusionDexmedetomidine pretreatment can attenuate focal cerebral I/R injury in a dose-dependent manner through improvement of brain cell energy metabolism and reduction of lipid peroxidation and stress reaction.

Objective To investigate the effect of sevoflurane post-conditioning on the expression of poly (ADP-ribose) polymerase (PARP) in the cerebral cortex during focal cerebral ischemia/reperfusion (I/R) in rats and the mechanism.Methods Fifty-four male Sprague-Dawley rats,weighing 250-320 g,were randomly divided into3 groups (n =18 each) using a random number table:sham operation group (S group),I/R group and sevoflurane post-conditioning group (Sevo-pc group).The animals were anesthetized with intraperitoneal chloralhydrate 300 mg/kg.In Sevo-pc and I/R groups,focal cerebral ischemia was induced by middle cerebral artery occlusion using a nylon thread with rounded tip inserted into the right internal carotid artery and advanced cranially until resistance was met.The occlusion was maintained 1 h,followed by 24 h reperfusion.The animals in Sevo-pc group inhaled 2.7％ sevoflurane for 1 h starting from onset of reperfusion.At 24 h of reperfusion,neurological deficits were assessed,and then the rats were decapitated.The brains were immediately harvested for determination of the cerebral infarct size (by TTC staining) and expression of PARP in the ischemic cerebral cortex (by immunohistochemistry).The number of apoptotic cells was counted using TUNEL.The apoptosis index was calculated.Results Compared with group S,the neurological deficit scores and apoptotic cells were significantly increased,the cerebral infarct size was enlarged,and the expression of PARP in the ischemic cerebral cortex was up-regulated in I/R and Sevo-pc groups (P ＜ 0.05 or 0.01).The neurological deficit scores and apoptotic cells were significantly lower,the cerebral infarct size was smaller,and the expression of PARP in the ischemic cerebral cortex was downregulated in Sevo-pc group (P ＜ O.05 or 0.01).Conclusion Sevoflurane post-conditioning can reduce focal cerebral I/R injury in rats and down-regulation of PARP expression in the cerebral cortex may be involved in the mechanism.

Objective To investigate the influence of t he mass screening on the diagnostic status of the conventional ordinary prostati c cancer (CaP). Methods Sixty seven cases of prostate ca ncer detected by mass screening (January 1996～December 2001) and 358 cases diag n osed at the outpatient of various hospitals in Changchun (January 1986～December 2001) were compared in terms of age distribution,clinical stages,level of serum prostate special antigen(PSA),pathological grade and treatment modalities,with a SPSS analysis system. Results The annual average incide nce of CaP during 1999 to 2001 increased 4.72 times when compared to the 1986 to 1989’s.In the screening group,the cases with clinical stage A and B accounted for 58.2%. In the clinical group, it was only 27.9%,and mostly detected incident ally.Furthermore,in the screening group the percentage of the cases beyond 20 ng /ml PSA and of poorly differentiated carcinoma were much lower compared to the c linical group.These differences were statistically significant.The cases of radi cal prostatectomy in the screening group increased 15.3% compared with that of t he clinical group. Conclusions Only the mass screening c an really reveal the actual prevalence of prostate cancer.It can markedly raise the number of prostate cancer,especially the cancer in the early stage.The mass screening is inevitable to detect the curable early stage prostate cancer.

Objective To study the therapeutic effect of pingyangmycin local injection under suspension microlaryngoscopy for treatment of laryngopharyngeal and laryngeal hemangioma. Methods The total of 44 cases of patients with laryngopharyngeal or laryngeal hemangioma were randomly divided into the experimental group ( n=22 ) and the control group (n=22). They were treated with bleomycin 5 mg or pingyangmycin 4-8 mg injection under suspension microlaryngoscopy in the hemangioma, respectively. If the treatments were not curative, repeated one more times in intermittent 15 d, but not more than 3 times. Therapeutic effect and adverse effect were recorded and analyzed. Results The total effective rate (95. 4%)in the experimental group was significantly better than that (59. 1%) in the control group (P<0. 05),and side reaction in two groups showed no significant variation. Conclusion Pingyangmycin local injection for treating laryngopharyngeal and laryngeal hemangioma is effective, less adverse reaction.

Objective To analysis the consequence of current perception threshold (CPT) by different frequency and time of transcutaneous electrical nerve stimulation (TENS). Methods CPT of foramen area and arm area was measured to evaluate the effect of TENS. Different frequency and time of TENS was given to 30 healthy volunteers. Stimulating to Hegu, CPT of the foramen area and the arm area on the same side was measured. Results CPT of the foramen area increased with stimulation. Low frequency of TENS inhibited the chronic pain significantly(P＜0.05),high frequency of TENS inhibited both of the chronic pain and the acute pain(P＜0.05). The inhibition of pain is more influenced by the frequency of TENS than the time of it. Conclusion Channel and point of TENS can influence CPT of the specific reaction area. And the choice of appropriate frequency of the treatment is more important than extending the treatment time alone.

A female patient with a dark red mass in the of preauricular area for over 3 months was hospitalized. Enhanced CT scan and ultrasonography showed that the mass had clear boundaries and was rich in blood supply. The patient was misdiagnosed as preauricular hemangioma, then the mass was removed as a benign tumor and found irrelevant to parot, SMA(+), Vim(+), S-100(+), indicating myoepithelial carcinoma. So a radical excision was performed to get negative incised margin. The patient didn't undergo postoperative chemotherapy but demonstrated no evidence of recurrence over a 12-month follow-up.

Objective To explore the spread patterns of retropharyngeal lymph node (RLN) metastasis of nasopharyngeal carcinoma. Methods From July 2003 to March 2005, three hundred and three patients with nasopharyngeal carcinoma in initial treatment were enrolled in this study. All patients underwent magnetic resonance imaging (MRI) before treatment, meanwhile measured the minimal and maximal axial diameters, the longitudinal diameter and the central and craniocaudad locations of each positive RLN. Results A total number of 264 positive RLN were found in 177 patients. The minimal and maximal axial diameters and longitudinal diameter of positive RLN were 9.9, 12.9 and 22.4 mm, respectively. Ipsilateral metastatic RLN were noted as follows: two nodes in 21 patients, three nodes in 3 patients and four nodes in 1 patient. According to the longitudinal central location of 263 positive lateral RLN, the numbers of nodes at occipital bone, C1, C1/C2, C2, C2/C3 and C3 were 27, 166, 40, 23, 5 and 2, respectively; the mean minimal axial diameters of nodes were 6.8, 9.9, 12.5, 10.4, 9.3 and 8.0 mm, respectively. Conclusion Multiple metastatic ipsilateral RLN are not common in NPC. The rate of RLN metastasis shows the trend of decreasing from vertebral C1 to C3.The maximal diameters of RLN are in the C1/C2 intervertebral space, and reveal a decreasing frequency along the craniocaudal directions of occipital and vertebral C1.
