Calcitonin gene-related peptide (CGRP) play a key role in some physiological and pathological progresses. The latest studies indicate that CGRP might involve in some disease progress and has a close relation with wound healing. It is significant to further investigate and then apply it to clinical diagnosis and therapy as well as forensic pathology.

OBJECTIVETo compare the chronic changes between the sacroiliac joints (SIJ) and the spine or the hip joints in conventional radiography of patients with ankylosing spondylitis (AS) and discuss the clinical staging of this disease.

METHODSAll images of the joints of the AS patients were evaluated twice in blinded manner by two doctors. The cervical spine, lumbar spine, sacroiliac joints and hip joints were separately evaluated by BASRI, and the results were averaged and analyzed. Definite involvement was defined as a score > or=2.

RESULTSThirty-seven AS patients (81.0% male with mean age of 28.49 years) were examined, and 81.0% of them had definite involvement of the spine and 40.5% of hip involvement. Pearson product-moment correlation coefficient was 0.459 between BASRI-SIJ and BASRI-s, and 0.465 between BASRI-SIJ and BASRI-h.

CONCLUSIONSeparately, the severity of SIJ changes can not represent the severity of changes in the spine and hip, etc, therefore SIJ changes may not be sufficient evidence for AS staging.

OBJECTIVETo determine the difference of post-operative mortality between ORIF (open reduction internal fixation) and hip replacement for the treatment of intertrochanteric fracture in elderly by using survival analysis.

METHODSThe clinical data of 110 patients above 60 years old who underwent surgical treatment (ORIF or hip replacement) for the intertrochanteric fracture between April 2003 and May 2013 were retrospectively analyzed. Among the patients, 83 cases were treated with ORIF (ORIF group), there were 32 males and 51 females, aged from 61.44 to 98.75 years old with an average of (78.52 ± 7.98) years old; and 27 cases were treated with hip replacement (arthroplasty group), there were 8 males and 19 females, aged from 71.82 to 96.54 years old with an average of (79.99 ± 6.11) years old. A survival analysis was performed on the clinical data by using SPSS 110 software. The survival rate of 1-year,2-year, 5-year and the mean survival time for the total patients, the mortality rate of 1-year, 2-year in each group, the survival rate of 1-year, 2-year and mean survival time and survival curve in each group were included.

RESULTSAll wounds achieved primary healing and no deaths were found in stay hospital. All patients were followed up from 1 to 125 months with an average of (46.93 ± 29.53) months. Among all 110 cases, 31 were dead and 79 survived. The survival rate of 1-year, 2-year and 5-year was (90.7 ± 2.8)%, (82.5 ± 3.9)% and (57.6 ± 6.5)%, respectively,while the ensemble mean survival time was (84.137 ± 5.902) months. The mortality rate of 1-year, 2-year in ORIF group was 7.2% and 12.0%, respectively; and in arthroplasty group, there was 14.8% and 25.9%, respectively. There was no significant difference in mortality rate of 1-year and 2-year between two groups. According to the survival analysis of the ORIF group, the survival rate of 1-year, 2-year was (92.6 ± 2.9)%, and (85.8 ± 4.3)%, respectively, and the mean survival time was (87.508 ± 6.063) months. In arthroplasty group, the survival rate of 1-year, 2-year was (85.2 ± 6.8)% and (73.9 ± 8.5)%,and the mean survival time was (67.294 ± 11.180) months. There was significant difference in mean survival time between two groups (P < 0.05).

CONCLUSIONORIF can achieve a better postoperative survival compare with hip replacement in treating intertrochanteric fracture in elderly.

OBJECTIVETo study the diagnostic value of diffusion tensor imaging (DTI) in cervical spondylotic myelopathy.

METHODSTwenty healthy volunteers and fifty patients with cervical spondylotic myelopathy underwent DTI in the Affiliated Hospital of Medical College of Ningbo University from January 2014 to April 2015. Healthy volunteers served as controls. Fifty patients were divided into three groups (group A , B, C) according to cervical MRI scan standard. Group A (17 cases) had only the dura mater spinalis compressed; Group B (23 cases) showed the cervical spinal cord compressed, but no high signal in it; Group C (10 cases) had the cervical spinal cord compressed with high signal in the same level. The average apparent diffusion coefficients(ADC) and fractional anisotropy (FA)values in these examinee were analyzed and all subjects were performed fiber tracking.

RESULTSThere was no statistically significant differences in ADC and FA values in C2/C3, C3/C4, C4/C5, C5/C6, C6/C7 of control group (P>0.05). The average ADC and FA values in control group were (0.875 +/- 0.096) x10(3) mm2/s and 0.720 +/- 0.051, respectively; compared with group A,there was no statistically significant difference; compared with group B and C, there was significant difference; comparison among group A, B, C, there was significant differences.

CONCLUSIONDTI can early and accurately quantify the changes of microstructure in cervical spondylotic myelopathy. Fiber tracking can show the damage range of spinal cord lesions.

Objective To explore the application and effect of aggameline in the treatment of depression. Methods 150 patients with depression treated in our hospital from January 2015 to December 2016 were randomly divided into three groups: A, B and C, 50 cases in each group. Group A was treated with rosiglitamine, group B was treated with venlafaxine, group C was treated with paroxetine. The improvement of symptoms before and after treatment in the three groups was observed[ (Hamilton Depression Scale (HAMD), Hamilton Anxiety Scale (HAMA)], Sleep Quality [Pittsburgh Sleep Quality Index (PSQI), Sleep Self-Rating Scale (SRSS)] and cognition Function [repeat sets of neuropsychological state test (RBANS), connection test (TMT)], and adverse drug reactions were recorded. Results After four weeks of treatment, the scores of HAMD and HAMA in the three groups were lower than those before treatment (P<0.05). The results of HAMD score showed that group B (P<0.05), but there was no significant difference between group A and group C. After treatment for four weeks, the scores of PSQI and SRSS were lower than those before treatment (P<0.05). There was no significant difference between group A and group B (P<0.05). After treatment, the scores of RBANS were higher than those before treatment (P<0.05), and delayed memory, attention to the two groups in group B> group C (P<0.05), There was no significant difference between the two groups in immediate memory; there was no statistically significant difference between the three groups after treatment and speech and visual acuity scores. After 4 weeks of treatment, the time to connect and connect sequentially was shorter than that before treatment (P<0.05), and the order of alternating time showed that group A

Sudden infant death syndrome is known as sudden death in 12 months postnatal without obvious cause, the cause of death and differential diagnosis of still couldn't be indefinite so far. In this paper, the recent studies on the SIDS neuropathology using immunohisto-chemical technology were reviewed in order to suggest the lethal patho-physiologic derangement or mechanism in SIDS involves dysfunction of sleep-related cardio-respiratory homeostatic controls or failure to arouse. Thus the main cause of SIDS lies in central nerve system, but not unique cause.

OBJECTIVE: To study the changes of HSP 70 mRNA and c-fos mRNA expression and to find a method to differentiate antemortem from postmortem electrocution. METHODS: Fifteen New Zealand rabbits were randomly divided into three groups, the antemortem electrocution group, the postmortem electrocution group, and the control group. Each group consists of five rabbits. The levels of HSP 70 mRNA and c-fos mRNA in skeletal muscle and cardiac muscle were examined with quantitative fluorescent RT-PCR. RESULTS: The levels of HSP 70 mRNA and c-fos mRNA in the antemortem electrocution group increased significantly (P<0.05), compared with that of the postmortem electrocution group. CONCLUSION The changes of HSP 70 mRNA and c-fos mRNA expression in skeletal muscle and cardiac muscle can be used as an indicator to distinguish antemortem from postmortem electrocution.

OBJECTIVETo investigate and re-evaluate the relationship between burn wound sepsis and tissue bacterial quantity.

METHODSThirty-two patients admitted during past 5 years were enrolled in the study. Bacterial isolation and quantity in burn wound tissue were carried out. Meanwhile clinical signs were evaluated for the staging of burn wound sepsis.

RESULTS1) Bacterial invasion could be identified in 123 pieces of tissue samples from 32 patients. Samples with tissue bacterial quantity > or = 10(5)/g were found in 82 subeschar tissue samples, and 41 samples with bacteria <10(5)/g. Subeschar tissue samples with bacterial quantity > or = 10(5)/g could be determined in 68 samples from 18 patients, and < 10(5)/g in 20 samples from 5 cases. In addition, samples of subeschar tissue with bacterial quantity > or = 10(5)/g could only be found in some of the samples form 9 cases. 2) Burn wound sepsis could be classified into I-IV stages according to tissue bacterial quantification and clinical signs.

CONCLUSIONBurn wound sepsis could be established by identification of bacterial invasion into living tissue with clinical symptoms of toxemia.

OBJECTIVETo investigate the cough-relieving, analgesic and antibiotic effects of durian shell extract (DSE) in relieving cough and its analgesic and antibiotic effects.

METHODSThe effect of DSE in relieving cough was assessed in mice challenged with ammonia and SO(2) to induce coughing. The analgesic and antibiotic effects of DSE in mice were evaluated by hot plate test and twisting reaction induced by acetic acid, and by minimal inhibitory concentration (MIC) and disc-agar diffusion tests, respectively.

RESULTSCompared with the control group, the mice treated with 300 and 900 mg/kg DSE showed significantly prolonged latency with decreased number of coughing induced by ammonia and SO(2), and the effect was dose-dependent. DSE markedly prolonged the latency and decreased the twisting number of the mice induced by acetic acid without affecting the pain threshold in hot plate test. DSE produced no significant inhibitory effects against Staphylococcus aureus, Staphylococcus epidermidis, or E. coli, and showed a week inhibition against Bacillus aeruginosus.

CONCLUSIONDSE shows obvious effect in relieving cough and produces better analgesic effect against chemical factor-induced pain than against physical agent-induced pain sensation. DSE has a moderate inhibitory effect against Bacillus aeruginosus.
