This report presents two cases of unilateral acute labyrinth loss resulted from injury,each showing delay in compensation possibly due to long-term administration of diazepam.The recent literature of the effects of the drugs onyestibular compensation is reviewed.The vestibular"suppressants"property of diazepam delays compensation when used on a long-term basis.However,it might be useful in controlling vege- tative symptoms and thereby possibly facilitate compensation when used on a short- tern basis.

Objective To investigate the psychological state and its correlation factors of family members of elderly cancer patients. Methods A total of 76 family members of elderly cancer patients were investigated with questionnaires with Zung's self-rating anxiety scale (SAS) and self-rating depression scale (SDS). Their psychological state and its correlation factors were analyzed. Results Incidence rate of anxiety of elderly cancer patients' family members was 52.63%, and incidence rate of depression was 46.05%. The mean standard score of SAS and SDS of elderly cancer patients' family members were both significantly higher than domestic norm. Difference of family member's gender, ways to pay health care fee, pain degree and disease condition led to different SAS and SDS score. Conclusions Family members of elderly cancer patients possessed different degree of psychological obstacle which related with multiple factors. Medical staff should not only think highly of patients' psychological state, but also their family members'. And meanwhile they should take corresponding strategy to reduce the incidence rate of anxiety and depression state in those family members.

Objective The purpose of the present study was to explore the use of psychological intervention in modified electroconvulsive therapy patients.Methods Divide all 160 patients random into two groups,the intervened group and the contrast group. The intervened group was accepted psychological intervention before the therapy day;The contrast group just did as normal.Record the anxiety, blood pressure,heart rate and the agreement to the therapy of the two group before the therapy.Results The anxiety of the intervened group was much little to the contrast group.The blood pressure and the heart rate of the intervened group was lower than the contrast group.Patient of the intervened group was much active to match with the treatment. Conclusions The use of psychological intervention in modified electroconvulsive therapy patients could decrease patient’s anxiety and painness,made them more active to match with the treatment.

Objective:To generate rabbit anti-human Fc?/?R and Poly Immunoglobulin Receptor(pIgR) polyclonal antibodies.Methods:The EC12 domain of human Fc?/?R and the D1 domain of pIgR were expressed as including bodies in Escherichia coli.The purified proteins were used to immunize rabbits to generate polyclonal antibodies.The immune sera were characterized by ELISA and Western blot analysis,then absorbed with cross-action and purified by antigen linked beads.Results:The titers of antiserum were 1∶6 4000 and 1∶25 6000,separately.There was little cross-reaction between the two immune sera.Conclusion:The polyclonal antibodies against human Fc?/?R and pIgR without cross-reaction were successfully generated and could be useful tools to study the relationship between the two receptors.

Objective To investigate the mechanism of acupuncture in anti-depression. Methods 100 depressive patients were randomly divided into acupuncture group and Amitriptyline group, 50 cases in each group. They were respectively treated by acupuncture at Neiguan (PC6), Sanyinjiao (SP6), Baihui (DU20), Fengchi (GB20), and oral western meicine. The needles were manipulated once every 20 minutes and treatment was given once a day. HAMD score and levels of serum cell factors of two groups were observed. Results Serum levels of interleukin 1? (IL-1?), interleukin-6 (IL-6) interleukin-2 (IL-2) and tumor necorsis factor-? (TNF-?) in depressive subjects before treatment were significanly higher than that of nomal subjects (all P

The effect of far ultraviolet radiation on scavenging active oxygen radiacal of polysaccharides from Sargassum thvnbergii and Sargassum kvrneri was studied. The results showed that the scavenging superoxide an ion radiacal levels of two polysaccharides were obviously decreased after 24h by UVc radiation,but the inhibition of the peroxidization of PU-FA was very prominent.The changes of IR spectra before and after far ultraviolet radiation on the two polysac-charide were also studied by differential scanning calorimetry(DSC)and infrared absorption spectroscopy(IR)

Objective To investigate protective of umbilical cord-mesenchymal stem cells ( UC-MSC ) on idiopathic pulmonary fibrosis ( IPF ) experimental mode was induced by bleomycin in mice .Methods IPF experimental mode induced by bleomycin with intratracheal injection , and then the fourth generation UC-MSC was injected in caudal vein.The lung tissues were obtained to evaluate the influence of UC-MSC on IPF by the observation of histological evaluation(HE) and Masson staining, the detection content of hydroxyprine(HYP), superoxyde dismutase(SOD) and malonaldehyde ( MDA) .Results The HE and Masson staining showed that bleomycin +UC-MSC group could alleviate inflammatory cell infiltration and pulmonary interstitial collagen deposition.bleomycin+UC-MSC group could decline the content of HYP(P<0.01), MDA(P<0.05) and improve the content of SOD(P<0.01)compared with bleomycin group.Conclusion UC-MSC exhibits an protective effect on IPF experimental mode induced by bleomycin in mice.

Parkinson's disease (PD) is a common neurodegenerative disorder with typical motor symptoms and a variety of non-motor symptoms,including neuropsychiatric symptoms,autonomic dysfunctions,abnormal sense,sleep disorders and fatigue.Studies showed that several non-motor symptoms,such as olfactory dysfunction,constipation,rapid eye movement sleep behavior disorder,depression and fatigue,can occur before the onset of motor symptoms.Fatigue has been considered as one of the most disabling symptoms,and it has a significant impact on activity of daily living and quality of life,and brings heavy burdens to caregivers.However,fatigue in PD has no special biomarkers,so clinicians are lack of the recognition and intervention.Here,we will expound the prevalence,risk factors,rating scales and potential mechanism relating to neuropathology,neuroinflammation and neurobiochemistry in PD patients with fatigue.

Universal uhrasound screening in newborn has been accepted for reducing the incidence of late detected developmental dysplasia of the hip (DDH).Unfortunately, the neonatal ultrasound screening strategy has not been applied in the mainland of China, which leads to a high incidence of late-detected DDH.Before implementing the neonatal ultrasound screening strategy, the clinical screening by limited abduction is valid to early diagnose the dislocated hip joint.Additionally,it is necessary to screen all the newborn with high risk factors of DDH, such as positive family history, breech presentation and postnatal hip extended swaddling.Early screening of DDH is the common responsibility of child care doctors, including community health physician, pediatrician or pediatric orthopedist.Currently, it is imperative to build regional neonatal ultrasound screening system for DDH in the regions with tertiary pediatric orthopedic center.

ObjectiveTo compare the levels and locations of metalloprotionase-2（MMP-2），collagen types Ⅰ and Ⅵ in keratoconus and normal human corneas．MethodsAn immunoperoxidase and indirect immunofluorescent technique were used to visualize the presence of collagen types Ⅰ， Ⅵ and MMP-2．The immunohistochemical staining was further analyzed and the intensity of reaction products was measured with an Image-processing system．ResultsCollagen type Ⅰ was demonstrated immunohistochemicall and indirect immunofluorescent technique in the bowman and stroma layers；collagen type Ⅵ was in epithelium basement，bowman，stroma and descement layers；MMP-2 was in epithelium，stroma and endothelium of all corneal sections．Compared with normal control specimens，the staining intensity of collagen types Ⅰ and Ⅵ was similar，while MMP-2 was markly increased．ConclusionsKeratoconus contained an increased level of MMP-2 and similar of collagen levels．These results lead further support to the hypothesis that degradation processes may be aberrant in keratoconus．
