Objective To study the clinical application of trigemino-cervical reflex(TCR)in migraine without aura(MWOA)and chronic tension-type headache(CTTH).Methods The TCR was recorded using surface electromyographic recordings bilaterally from the sternocleidomastoid muscle after stimulation of infraorbital branch of the trigeminal nerve.The reflex was investigated in 25 patients with unilateral MWOA,25 patients with CTTH and 36 healthy subjects.The patients were outpatients who visited Fujian provincial institution hospitals from January 2009 to February 2010.Results Compared with the healthy subjects,the bilateral peak latency of P19/N31(PLP19 and PLN31)was significantly shortened in the subjects with MWOA(left and fight side were(19.49 ± 1.95)ms and(19.81 ± 1.79)ms respectively)or CTTH(left:(19.56 ±2.02)ms,and right:(19.16 ± 1.67)ms),t values were between 2.027 and 3.654,all P ＜ 0.05.The values of PLP19 and PLN31 between the patients with MWOA and with CTTH were not significantly different.Conclusions The peak latency of P19/N31 was shortened in the subjects with MWOA or CTTH,suggesting that the trigeminal and brainstem may participate in the pathophysiology of MWOA and CTTH.There was no significant difference in PLP19 and PLN31 between the patients with MWOA and CTTH,indicating similar abnormalities in the endogenous pain control mechanisms in both migraine and

Leptin,the product of the obese gene,is a protein produced and secreted primarily by adipose tissue.Leptin initiates several biological effects by binding to its receptors.Many studies have shown that leptin can reduce fat accumulation,but its mechanism is still unclear.This article reviewed the effects of leptin on lipogenesis,and especially on proliferation and differentiation of preadipocytes.

Objective To assess and compare the Beck Depression Inventory-II ( BDI-Ⅱ) , Hospital Anxiety and Depression Scale-Depression Subscale ( HADS-D) and Center for Epidemiologic Studies Depression Scale ( CES-D) as screening instruments for depression in patients with epilepsy .Methods One hundred and seventeen patients diagnosed with epilepsy were evaluated by BDI-Ⅱ, HADS-D and CES-D, the performance of BDI-Ⅱ, HADS-D and CES-D was evaluated by ROC curve .Results There were 33 epileptics with depression .The sensitivity and specificity of BDI-Ⅱfor the diagnosis of depression was around 90% for critical value 16, the sensitivity of CES-D was more than 80%for critical value 15, and specificity was 72.6%.The sensitivity and specificity of HADS-D was more than 80%for critical value 9, and the sensitivity of HADS-D was 91.3% for critical value 7, and specificity was 76.8%.Three instruments showed a negative predictive value of over 90%.Comparisons of the areas under the ROC curve for these instrument were not statistically significant difference (all P>0.05).Conclusion HADS-D is a brief efficient screening instruments to identify depression in patients with epilepsy .

Objective To evaluate the effect of oral health instructions in nursing of marsupialized jaw cysts. Methods 46 patients with cysts of jaw were divided randomly into two groups (education group and control), 23 in each. In addition of normal nursing processes in both groups, patients in education group were offered more oral health instructions, such as pathogenesis of jaw cysts, mechanism of marsupialization, wear and clean of a cyst plug, and oral hygiene maintenance. 12 months later, compliance, satisfaction, treatment effect and oral hygiene condition of the patients in the two groups were studied and compared. Results 100%of patients in the education group could return to clinical visits on time and 96%of patients did cyst rinsing after every meal, which were significantly higher (χ2=6.9, P<0.05) than in the control (74% and 70% respectively). Patients′satisfaction in the two groups were also significantly different (χ2=9.109,P<0.05). Patients in the education group were much more satisfied with the treatment procedures than control. The treatment effect of the cyst in the education group [good (83%), moderate (17%), not so good (0%)] was significantly (χ2=7.793, P<0.05) better than control (good (43%), moderate (52%), not so good (5%)]. The secondary infection rates in the two groups were similar (χ2=1.022, P>0.05). Oral hygiene condition of patients in the education group was better than control in Debris Index (χ2=9.576, P < 0.05) and Plaque Index (χ2=8.212, P < 0.05). Conclusions Oral health instructions played positive role in improving patients′ compliance, degree of satisfaction, treatment effect and oral hygiene condition in patients with jaw cysts.

Objective To determine the relationship between time management disposition and subjective well-being among the head nurses.Methods Totally 388 cases in third-grade class-A hospitals in Chengdu were investigated with Time Management Disposition Scale and Subjective Well-being Scale.Results The higher the scores in time management disposition,the higher the scores of the head nurses in subjective well-being.There was a significant positive correlation between time management disposition and subjective well-being.Among which,time efficacy feeling and time monitoring view had significant predictable effect toward subjective well-being.Conclusions Time management disposition had significant influences on subjective well-being.It indicates that we can improve subjective well-being and promote mental health of the head nurses to a certain extent through strengthening time management training to improve time management disposition level.

The characteristic feature, tissue structure and chemical composition of primitive bark and one to four years regenerated bark of Eucommia ulmoides were compared, and the contents of elastic rubber thread, chlorogenic acid and ethanolic extract of the two barks were determined Res ilts showed that regeaerated bark is of the same quality as primitive bark.

[Objective] To explore the bone histomorphology effect of QiangGuYin on neck of femur of ovariectomized rats.[Methods]Ninety femal SD rats,weight 230～280 gram,were rangdonmized into three groups:QiangGuYin group(treatment group),Miacalcic group(contrast group)and control group.All rats were variectomized.After 10 weeks,the osteoporosis model succeed,the treatment group,contrast group were given QiangGuYin,Miacalcic respectively.The treatment group used QiangGuYin everyday,1ml/g.The contrast group used Miacalcic 0.72u/kg,everyday hyodermic.And 3,4.5,6 months after the treatment,kill 10 rats to explore.The neck of femur were cut and stined with Masson Golder Trichrome for bone histomorphomemetric contrast group analysis.[Result]The treatment group ovariectomized rats' in 3m,BV/TV compared with statistical significance;compared with control group in Tb.sp,BV/TV,Tb.Th with statistical significance.After 4.5m treatment group Tb.Th compared with contrast group have statistical significance.Give the medicine 6m,Tb.sp,Tb.Th compared with contrast group all have statistical significance.[Conclusion]Giangguyin can effectively improve the histomorphometry index.The mechanism probably is stimulating osteogenesis and supperssing the cytoactive of osteoclast and trend of the high bone transform.

Rabbits were intoxicated with hypodermic injection of 0.8% CdCl2 in normal saline every other day for 3 months,and the blood level of urea nitrogen (BUN) and creatinine (Cr) and the activities of Na/K-ATpase,Ca-ATPase,and ?-GT in the renal cortex were determined.It was found that there were no remarkable changes of BUN and Cr level but significant reduction of the activities of the 3 enzymes.It is believed that the reduction of the enzyme activities is one of the factors to initiate the functional disturbances and morphological damages of the kidneys and plays an important role in the mechanism of renal failure if it is not promptly corrected.

Objective To investigate the incidence,original location and clinical features of olfactory sulcus polyp in patients with chronic sinusitis.Methods Two hundred and seventeen cases(351 sides) with chronic sinusitis were reviewed,their olfactory sulcus was carefully examined with nasal endoscope during operation.The incidence and original location of olfactory sulcus polyp were observed,and the relationship between olfactory sulcus polyps and prognosis of chronic sinusitis or olfaction of the patients with olfactory sulcus polyps were also statistically analyzed with Chi-square test and Spearman rank correlation.Results The incidence of olfactory sulcus polyp in the cases with chronic sinusitis was 18.52%.Among these cases with olfactory sulcus polyps,the rate of olfactory disorder was 81.82%,which was higher than that in the cases without olfactory sulcus polyps(25.63%,P
