Objective: Exploring the developmental vitial moments and process of career identity.Methods: A case subject was administered structured interview and tested by Career Identity and the Related Factors Questionnaire,Chinese Self-Efficacy Scale,QZPS and MBTI-G.Results: There were several vital moments in the process of career identity,such as the first time to think about career identity,and select a major,the first time to choose career and get employed,meet the organizational changes,find a new job again and get promotion.The present crisis of career identity reflected some unresolved problems of previous developmental periods.Conclusion: The individual's objective behavior toward career choice,decision-making,continuous exploration and efforts were of great benefit to career identity.

Objective:To alarm the effect of statins on blood glucose, and provide evidence for the rational use of statins in clin-ics. Methods:The recent articles on the effects and potential mechanisms of diabetogenic action of statins were reviewed and summa-rized. Results and Conclusion:Stains, especially lipophilic stains, could increase blood glucose via multiple pathways to induce dia-betes. The potential mechanisms included inhibiting L-type calcium channel, increasing the uptake of plasma-derived LDL-C, inhibi-ting synthesis of ATP and Coenzyme Q10, inhibiting the expression of glucose transporter 4 and inducingβ-cell inflammation, oxidation and apoptosis. Blood glucose should be monitored and adjusted timely when statins are used in clinics.

Binding sites or receptors for prolactin were identified in crude membrane fractions prepared from female lactating Sprague-Dawley rat using receptor radioassay. The results further indicated that the membrane of rat liver cells are rich in prolactin receptors, and the Scatchard analysis of the binding of ~(125)I-oPRL to receptors revealed that female rat liver cells contained two classes of prolactin receptors (Kd_1=3.20?10~(-10) M, Kd_2=1.26?10~(-8)M) with high specificity.

Objective: To explore the feature of theory of mind(ToM) in schizophrenic patients and the influencing factors. Methods: Subjects were 108 patients with schizophrenia, 21 with affective disorders and 21 normal subjects. Picture-story tasks, PANSS and WAIS-R were used to assess the patients' ToM, symptoms and intelligence. Results:It was found that the scores on first-order theory of mind tasks of schizophrenic patients with IQ below 70 were lower than normal subjects'(D = -56.58,P

Objective To investigate the effect of low-intensity ultrasound on intraocular hypertension and its mechanicsm.Methods The intraocular hypertension rabbits were treated with ultrasound.The intraocular pressure(IOP),trabecular meshwork HE staining,EM microscopy,extracellular matrix through immunohistochemistry were performed.Results After treatment,IOP was descended and trabecula interspace was wider than the control eye.The expression of collagen I,laminin and fibronectin was inhibited.Conclusion Low-intensity ultrasound can decrease IOP.It may be related with the change of histologic structure of trabecular meshwork.

Results The total effective rate of the treatment group and the control group was 90% and 73.3%, respectively, showing significant difference (X2=4.011, P <0.05 ) . Conclusion Modified Shenghua decoction plus western medicine is effective in treating, primary dysmenorrheal.

There were 417 scientific articles on hematopoietic stem cell transplantation in the 54th annual meeting of American Society of Hematology (ASH),including 46 articles on lymphoma.This article reviews latest research on non-myeloablative allogeneic hematopoietic stem cell transplantation for the treatment non-Hodgkin' s lymphoma presented in the meeting.

Objective To investigate whether there are different effects of electric stimulation of vagus nerve,peripheral nerve(sciatic nerve and trigeminal nerve),and motor cortex on pentylenetetrazol (PTZ)induced convulsion in rats.Methods The vagus nerve and sciatic nerve were exposed in rats.The stimulation electrodes were placed on the vagus nerve,sciatic nerve,trigeminal nerve,and motor cortex,respectively.After electric stimulation,PTZ(50 mg/kg)was intraperitoneally injected into the rats.The pattern and latency of the convulsion seizure were observed and recorded.Results Racine's grade Ⅰ-Ⅴ grade convulsion seizure Was present in 9 rats(9/10)in the control group after the injection of PTZ.However,this intensity Was reduced to Ⅰ-Ⅲ grade differentially in all the rats by electric stimulation of the vagus nerve(5/10)or peripheral nerve(6/10 and 5/10).Furthermore,in the group of rats stimulated at motor cortex,there Was completely no convulsion.On the other hand,when pathological changes appeared in cortex or hippocampus(i.e.epileptic model was set up by 7 weeks stimulation),the same stimulation of motor cortex was not able to inhibit the convulsion seizure induced by injection of PTZ and all these rats showed Ⅳ-Ⅴ grade seizure(10/10).Conclusions In physiological condition,all of the four types of stimulation differentially reduced intensity of convulsion seizure triggered by PIZ injection and motor cortex stimulation has the best effect.However.when rats were in pathological status and epileptic nidus appeared in their brains.stimulatiion of motor cortex has no effect on PTZ induced convulsion seizure.

Aim To explore the modulation of Salvia miltiorrhiza on hyperpolarization-activated current (Ih) channels in dorsal root ganglion (DRG) neurons of rats and identify the mechanism of Salvia miltiorrhiza in alleviating pain and inhibiting calcium overload. Methods The effect of Salvia miltiorrhiza injection on Ih channels in DRG neurons of rats were examined by using whole-cell patch clamp technique. Results The experimental results showed that the amplitude of Ih evoked by -150 mV was (-1.06±0.18) nA. The Ih could be fitted well into the single kinetics and the time constant of activation, τ was clearly voltage-dependent with τ=(322.14±28.81) ms at -100 mV, decreasing to τ=(62.51±9.78) ms at -150 mV. The reversal potential of Ih was (-35.03±1.12) mV measured from tail currents. But no significant differences were found between the DRG neurons in the absence and presence of Salvia miltiorrhiza injection (10%, 25%, 50%) in the current amplitude, the time constant of activation and the reversal potential. The only difference between the DRG neurons in the absence and presence of Salvia miltiorrhiza injection was the half-activation potential of Ih. In control recordings the half-activation potential was (-106.07±3.59) mV. By comparison, the half-activation potentials changed to (-111.59±3.79) mV (n=31 neurons, P＜0.05), (-119.37±4.96) mV (n=31 neurons, P＜0.05) and (-121.23±3.86) mV (n=31 neurons, P＜0.05) in the presence of 10%, 25%, 50% Salvia miltiorrhiza injection, respectively. Conclusion Only the half-activation potential of Ih in the arthritic and neuropathic rat models shifted in the depolarizing direction, which increased the electrophysiological activity of Ih and made it related to peripheral hyperalgesia. The selective inhibition of Salvia miltiorrhiza on the electrophysiological activity of Ih may be one of the mechanisms underlying its analgesic effects.

BACKGROUND: There has been no definite cause for Bell's palsy. Different kinds of causes and courses always lead to different outcomes. Up to now there has not been to accord on the relationship between assessment of facial muscle function and prognosis of Bell's palsy.OBJECTIVE: To explore the relationship between level diagnosis, blink reflex(BR) , electroneurography(ENoG) and prognosis in order to find the timing for treatment of Bell's palsy.DESIGN: A self-control study.SETTING: Department of otolaryngology, Beihai People's Hospital,Guangxi Zhuang Autonomous Region.PARTICIPANTS: There were 42 cases of Bell's palsy that were in accordance with the diagnosis criteria and hospitalized in the Beihai People's Hospital from January 1989 to December 1999. Thirty-six cases out of the 42 were well documented and thus were studied here.METHODS: Level diagnosis, BR and EnoG test as well as facial muscle assessment were conducted on thirty-six patients with Bell's palsy.RESULTS: Patients with facial function score under 11 and with the lesion at D segment had poor results in BR and ENoG test. The outcome of conservative treatment for these patients was also bad. That would be improved by facial nerve decompression. The results of examination within one month after palsy onset were correlated with prognosis ( P ＞ 0. 05) . Two cases received decompression on the 40th day onset and recovered completely. Two cases Received decompression in the 2nd month, one recovered completely and decompression and recovered partially.CONCLUSION: Patients with the following manifestations may make conplete recovery after conservative treatment: lesion distal to segment D, facial function over 11 marks, presence of R1 wave by BR test in the 1st month and fiber deprivation ＜ 90% by ENoG. Facial nerve decompression should be taken for patients in a condition other than that.
