Objectives To investigate the specific site for measuring inferior alveolar nerve canal (IANC) by cone beam computed tomography (CBCT),and to provide reference data of the course of the IANC of the crowd.Methods This study was a retrospective data analysis.One hundred and thirty CBCT cases were measured and compared after classification by gender and age (65 men and 65 women,65 middle age and 65 youth).Since the proximal center of the mental foramen area,the cross-section at which the mental hole just completely breaks the buccal cortical bone was defined as S1,and S2,S3,S4 were defined as cross-sections with 1-cm apart from each other since S1.L1,L2,L3,and L4 were measured as the distance from specific sites on the outer wall of the IANC to the alveolar crest,the outer wall of lingual lateral cortical bone,the mandibular minimum margin,and the outer wall of buccal cortical bone.The results were analyzed using independent samples t test,with P＜0.05 being considered statistically significant.Results On the right IANC S2L1,S3L1,S4L1,S2L2,S3L2,S4L2,S1L3,S3L4,the 8 groups of L values measured on these 8 sites,all showed differences between genders (P＜0.05).So did the 10 groups of L values measured on the left IANC S1L1,S2L1,S3L1,S4L1,S1L2,S3L2,S4L2,S2L3,S3L3,S4L4 (P＜0.05).The middle age group and the youth group were statistically different for the data measured on the right IANC S2L4 (P＜0.05).This was the same case for the data measured on the left IANC S1L3.When classified according to gender,L1 in the S1 to S4 sections firstly increased and then decreased,and eventually decreased.The change pattern of L3 was opposite to that of L1.L2 in the S1 to S4 sections firstly decreased and then decreased,and eventually increased.The change pattern of L4 was opposite to that of L2.When the samples were classified according to age,the change pattern L value in the S1 to S4 sections was the same as that under gender classification.Conclusions The effect of gender on the L value of individuals is relatively great,while the effect of age on the L value of individuals value is very small.Setting the corresponding long axis of mandible as a reference,the change pattern of IANC in the mandible can be deduced based on the change of L value from S 1 to S4:from S1 to S4,the course of IANC on the vertical direction is firstly downward,tben turns to upward and goes upward;from S1 to S4,the trend of IANC on the horizontal direction is firstly toward the side of tongue,and eventually turns towards the buccal side.The current study provides reference data for IANC-related anatomy from the mandibular foramen to the mandibular second molars.

To investigate the cause, clinical features, differential diagnosis and treatment of adrenal hematoma, 4 cases were studied retrospectively. Chinese literature was reviewed. There were 4 cases diagnosed as adrenal hematoma pathologically among 282 cases of adrenalectomy in Chinese PLA General Hospital. Two cases were suspected as adrenal adenoma and the others were found incidentally during nephrectomy. Forty six cases of hematoma were reported in 7 Chinese articles since 1979. 26 1%(12/46)were misdiagnosed as adenoma for surgical treatment and 73 9%(34/46)were followed up. It is very important to have sound knowledge to make a correct diagnosis of adrenal hematoma. It is helpful to inquire the case history in detail and to do B type ultrasound repeatedly, CT scanning or MRI with contrast. Follow up is reasonable if it is not suspected to have malignant or hyperfunctioning adenoma.

Objective To analyze post-traumatic growth of Chinese caregivers of dementia patients and to explore the caregivers′positive and potential energy, in order to formulate more perfect nursing intervention measures. Method Useing phenomenological method of qualitative research in selecting 6 dementia caregivers in-depth interviews to understand possible posttraumatic growth. Result Five major themes were found: changes in individual cognitive, changes in relations with others, promote their children′s education, reflections and concerns on status of pension-related changes in philosophy of life. Conclusions Dementia caregivers also have the positive performance of posttraumatic growth, in addition to the negative experience. Clinical nurses should actively explore the potential and power from the growth perspective. This is conducive to the caregivers with more health caring for life, so as to improve the quality of care, and ultimately improve the quality of life.

Objective To analyze and discuss the clinical effect of montelukast in the treatment of children with mycoplasma pneumoniae infection.Methods 21 7 children with mycoplasma pneumoniae infection were collect-ed,98 cases of airway height response after infection were selected as the research subjects in this observation,who were randomly divided into control group and observation group,among them 49 patients in the control group received conventional treatment,while 49 cases in the observation group added montelukast treatment based on the control group.The clinical effect and the occurrence of adverse reaction after 1 week of treatment were compared,at the same time,compared and discussed irritating cough onset,continue time,decrease time of cough and treatment time in the two groups.Results There were no adverse reactions in the two groups of children after treatment,98 cases were all cured,which suggested that the test was a complete success.The clinical efficacy of the control group after 1 week was 71 .43%,which was 97.96% in the observation group;In the control group,the duration of the stimulus onset,dura-tion,duration of treatment,treatment time and time of treatment were (5.20 ±2.64)d,(1 2.50 ±3.82)d,(1 3.1 0 ± 4.1 5)d,(20.80 ±1 0.65)d,which of the observation group were (4.1 0 ±0.27)d,(7.40 ±2.43)d,(8.90 ± 0.36)d,(1 6.40 ±8.32)d,the differences were statistically significant (t =2.901 ,7.885,7.057,2.279,all P <0.05).Conclusion Montelukast can promote and consolidate the curative effect in the treatment of airway hyper responsiveness in children with mycoplasma pneumoniae infection,it is recommended to promote in clinical because it has no serious side effects.

To explore the time-dependent of p harmacodynamics of lidocain alkalified solution. Method: On 8:00 am and 8:00 pm, surface anaesthesia and subarachnoid anaesthesia were con ducted in rabbits and 76 cases of surgical patients receiving epidureal anaesthe sia were observed in therapy effect.Results: The results of animal experimental showed the anaesthesia potency and anaesthesia incubatory period were better on 8:00 am than 8:00 pm; the clinical observation also obtain ed asimilar result. Conclusion: These results showed that lidocain alkalified solution had time-dependent of pharmacodynamics.
