Objective To observe the expression of the small heat shock protein (HSP27) in the optic chiasma (OC), optic tract (OT), dorsal lateral geniculate body(LG) and superior colliculus (SC) of the adult golden hamster after intraorbital transection of the left optic nerve (ON). Methods The experimental animals were left to survive for l, 2, 3, 4, 5, 6, 8 weeks following ON transection. The animals were perfused with formol-saline and brains were excised, sectioned and stained with the immunohistochemistry. The sections were observed under the light microscope, the optical density (A) was measured and the data were analysed statistically. Results Immunohistochemical results indicated that the HSP27-expressions were not different between the right and left side of the OC, OT, LG and SC in normal or sham-operation controls. However, following transection of the left ON, HSP27 immunohistochemical stainings in the right site of OC, OT,LG and SC were increased, comparing with the left side. The maximum difference of HSP27 immunostaining between the right and left side appeared in the lst week following left ON axotomy. The sharply decrease of the A difference occurred at the 2nd week after axotomy with insignificant changes in the subsequent several weeks. And the significant A difference was observed in most time except 6th week. Most of HSP27-positive cells had morphological appearances similar to astrocytes with smaller cell body and numerous processes. Conclusion After the transection of monolateral ON, HSP27 expressions in the contralateral optic pathway of brain increased and persisted up to 8 weeks. This result suggested that the increase of HSP27 expression had something to do with the injury of the optic pathway, but the mechanism and biological significance of the increase in HSP27 expression level required to be studied further.;

Objective To investigate the effect of ischemic preconditioning (IPC) on coronary microcirculation function in short-term hibernating myocardium(SHM) animal model.Methods Twelve little domestic Chinese pigs were established as the model of SHM by interventional method (closed-chest) and divided into 2 groups at random: the control group (CON group, n =6) and ischemic preconditioning group (IPC group, n =6).IPC was elicited by 2 cycle of 5 min of ischemia followed by 5 min of reperfusion before the establishment of model.Intracoronary Doppler guidewire was used to measure average peak velocity (APV),diastolic systolic velocity ratio(DSVR) and coronary flow reserve(CFR) of the distal to the stenosis at the baseline and 10 min,30 min,60 min,120 min after the establishment of model.Results APV,DSVR and CFR all decreased significantly in SHM model in both groups( P 0.05 ),at 60 min CFR of the CON group decreased significantly than before( 0.96 ? 0.27 vs 1.74 ? 0.49 , P 0.05 ).Conclusions The coronary microcirculation dysfunction happened at the time point of 60 min after coronary stenosis in SHM model,IPC can protect the coronary microcirculation function in SHM model.

ObjectiveTo explore the characteristics of nasal bone fracture caused by blunt instrument, including the fracture types, the fracture repair, and the difference of manifestations between X-ray and CT. To provide reference for the identification.MethodsThe information of basic situation, fracture site, injury manner, diagnosis method, expert opinion of 95 adult nasal fracture cases caused by blunt object, which occurred in Gutian county of Fujian province from January 1999 to December 2013, were ana-lyzed by descriptive statistics. The identification conclusions of different injuries were compared accord-ing to new and old standards as well.ResultsThere were total 95 adults including 87 male and 8 fe-male. The fracture site and quantity have significant correlation with the nasal bone anatomical relations and the direction and size of the force. Compound fracture was most common. The fracture that could not be determined by X-ray could be clearly diagnosed by CT examination. According to new and old standards, different fracture types have different identification conclusions.ConclusionThere are gender differences in nasal bone fracture cases. Larger external force is easy to cause compound fracture. CT examination is significantly better than X-ray examination.

Objective:To discuss the therapeutic effect of pharmaceutical care for old patients with chronic obstructive pulmonary disease ( COPD) . Methods:Totally 192 patients diagnosed as COPD were randomly divided into 2 groups according to a random num-ber table, 100 cases in the experimental group and 92 cases in the control group. The control group was treated with the conditional therapy, and the experimental group was treated with pharmaceutical care additionally. The studieds on COPD assessment test ( CAT) , modified British medical research council ( mMRC) and the value of pulmonary function index ( FEV1% index) were carried out and compared between the two groups. Results:There was no statistically significant difference in the CAT score, mMRC classification and FEV1% index between the two groups on admission (P>0. 05), however, after the treatment, the CAT score and mMRC classifica-tion were decreased and FEV1% index was increased in the two groups, and there was statistical significance between them ( P <0. 05). The CAT score and mMRC classification in the experimental group were lower and FEV1% index was higher than that in the control group(P<0.05). Compared with the medication errors(n=13, 14.13%) and incidence of adverse drug reactions(n=5, 5. 43%) in the control group, the medication errors(n=2, 2. 0%) and incidence of adverse drug reactions (0%) in the experimental group were significantly decreased. Conclusion:Clinical pharmacists provide effectively pharmaceutical care, which can significantly improve the clinical therapeutic efficacy in old patients with COPD.

Objective:To investigate the non-thymoma thymic morphology in patients with Myasthenia Gravis(MG), and provide the theoretical basis for extended thymectomy.Methods:From September 2008 to March 2018, extended thymectomy had been performed for 150 patients with MG in our department. In order to achieve maximal benefit, combined thoracoscopic and mediastinoscopic approach had been adopted to completely remove both thymus and ectopic thymic tissue in the neck and the anterior mediastinum. Cervical and mediastinal tissue including fat from the thyroid isthmus to the diaphragm was swept away from above the phrenic nerve. The regions containing mediastinal fat were divided into 12 stations.Results:There was no mortality. Pathology reports revealed 126(84.0%) patients with MG had hyperplastic thymus, 17(11.3%)cases with involuted thymus and 7 (4.7%)cases with normal thymus. 98 (65.3%)cases had more than two superior horns, and 59(39.3%) patients had ectopic thymic tissue in the mediastinum and in the neck. Positive rates of ectopic thymic tissue in the 12 cervical-mediastinal fat stations were 7.8%, 10.0%, 8.8%, 3.8%, 3.0%, 2.5%, 0, 0, 0.7%, 13.3%, 12.3% and 9.1%, respectively. After a follow-up period of 2-12 years, the rate of complete stable remission was 44.7%(59/132), and the effective rate was 89.4%(118/132).Conclusion:It is very meaningful to study non-thymoma thymic morphology in patients with MG in order to guide the performance of extended thymectomy and improve its outcome. For the purpose of minimally invasion, one side of mediastinal pleural should be carefully protected.

Objective In order to explore the possibility of autologous transplantation of olfactory mucosa for spinal cord repair,the changes of autologous olfactory mucosa being transplanted into spinal cord and the effect of promoting axon regeneration in adult rats were investigated. Methods Forty male adult rats were divided into two groups randomly:olfactory mucosa transplantation and control groups.Olfactory mucosa (1*!mm+2) was taken from the posterior region of nasal septum,and this graft was transplanted into the posterior funiculus of cervical 1 segment of spinal cord and destructed the corticospinal tract(2*!mm?1^5*!mm).The control graft was derived from the respiratory lamina and then was grafted into the corresponding lesion.After being survived for 4-6 weeks,the animals were killed,the transplanted site was sectioned horizontally,immunofluorescence double labeled with the neurofilament(NF) and anti-NGFR-p75,investigated under the confocal microscope.Another set of slice was used immunohistochemistry to investigate the olfactory mucosa how to integrate with the surrounding tissue. Results The control lesions have the obvious hollow,no p75-positive reaction in the respiratory lamina and no NF-positive fibers grew through it;olfactory mucosa group showed that olfactory mucosa which is labeled p75-positive healed up with surrounded tissue,the hollow declined markedly,the labeled olfactory ensheathing cells(OECs) soakage into the nerve tissue.OECs induced a fine,unbranched,elongative growth of the cut CST axons.The axons were regenerated through the graft and continued to reenter into the caudal host part.Conclusion Autologous olfactory mucosa may be the donor which could repair the spinal cord injury for clinical situations.

Objective To observe the clinical outcome of core decompression combined with autologous concentrated bone mar‐row cell transplantation for treatment of early osteonecrosis of femoral head .Methods Forty six patients (82 hips) included in this retrospective analysis were divided into observation group (30 cases ,44 hips) and the control group (26 cases ,38 hips) .The obser‐vation group were treated by autologous BMMSCs transplantation joint core decompression treatment while control group treated only with core decompression .The therapeutic effect of 2 methods of treatment were summarized by comparing the 2 groups after 3 ,6 ,18 months postoperative with Harris hip score and the imaging changes and necrosis area percentage change degree at 18 months postoperatively .Results The Harris scores of the observation group after operation increased significantly [(88 .24 ± 5 .53) score] ,the excellent and good rate was 84 .09% ;the Harris scores of the control group after operation increased significantly [(75 .48 ± 4 .20)% ] ,the excellent and good rate was 71 .05% ;MRI necrosis area of the observation group after operation reduced gradually[(13 .86 ± 4 .27)% ] and the MRI necrosis area of the control group after operation reduced gradually [(19 .53 ± 5 .29)% ] .There was significant difference between them (P<0 .05) .Harris scores and the imaging changes and necrosis area per‐centage change degree of both group had been improved after the operation (P<0 .05) .Conclusion The core decompression com‐bined with autologous concentrated bone marrow cell transplantation for treatment of early osteonecrosis clinical efficacy might be better than core decompression .

Using MS as basic medium, supplemented with 1.0 mg · L(-1) IBA, the adventitious roots of Tripterygium wilfordii were induced, and the good adventitious root culture system was established by leaves or callus induced by leaves as explants. The adventitious roots were also induced with 2.0-4.0 mg · L(-1) NAA and the good adventitious root culture system established by using suspension cells from callus as materials to induce adventitious root. The content of triptolide of three adventitious roots culture system were exceeded in the natural root bark. The content of triptolide of AR3 adventitious roots was the highest about 5.3 times as that in the natural root bark. By using 5 L stirred fermentor during pilot enlarge cultivation, compared with 250 mL flask cultivation, the adventitious roots increment and secondary metabolites content per liter medium showed no significant difference. The accomplishment of this analysis laid a foundation by tissue culture production of the secondary metabolites of T. wilfordii.

Objective Mycoplasma pneumoniae is one of the main pathogens of community-acquired pneumonia in children and teenagers , which may cause mycoplasma pneumoniae pneumonia ( MPP) .Atelectasis is one of the most common manifestations of MPP.The aim of the article was to evaluate the diagnostic and therapeutic value of fiberoptic bronchoscopy ( FB) in children with MPP associated with atelectasis . Methods Retrospective analysis were made on clinical data and FB records of 99 cases of hospitalized children with MPP associated with atelectasis from August 2010 to December 2012 . Results The positive rate of MP-DNA was 92.9%(92/99) in bronchoalveolar lavage fluid (BALF), and the positive rate of MP-Ab-IgM in serum was 68.7%(68/99).All pa-tients showed obviously bronchial mucosa congestive edema during FB examination .The results are as follows:bronchial phlegm bloc-king in 31 cases (31.3%), lumen inflammatory stenosis in 22 cases (22.2%),mucosal ulcer change in 7 cases(7.1%) and mucous nodular change in 3 cases (3.0%).4 weeks after being treated with bronchoalveolar lavage (BAL), only 3 cases remained in atelec-tasis, the partial and complete re-expansion rate reaching 96.5%(82 of 85). Conclusion The positive rate of BALF MP-DNA de-tection technology for the diagnosis of MP infection is higher than that of serum MP-Ab-IgM examination .Early interventional therapy by FB can shorten the course of disease and promote the lung re-expansion in children with MPP associated with atelectasis .

Objective To analyse the suspected hereditary non-polyposis colorectal cancer (HNPCC) in mismatch repair protein (MMR) expression of hMLH1 and hMSH2. Methods Immunohistochemical staining method was used for the detection of hMLH1 and hMSH2 protein expression in 193 cases suspected HNPCC patients, the deletion of MMR proteins was identified as highly suspected HNPCC cases. Results Of the 193 patients with suspected HNPCC hMLH1/hMSH2 abnormal expression rate was 29.02%; ≤30 years old was 40%, 31 ~ 40 years old was 28.05%, 41 ~ 50 years old was 28.71%,3 suspected HNPCC showed the deletion of hMLH1/hMSH2 protein expression at the same time ,; In the right colon , the left half colon and rectal anomaly detection rates were 40.74%, 32.65%and 18.89%; hMLH1/hMSH2 deletion was 46.15%with family history. Conclusions The deletion of MMR protein is closely related to age,site and family history in suspected HNPCC, and the deletion of hMLH1 is an important factor to induce early-set colorectal cancer. The deletion of hMLH1/hMSH2 at the same time indicates that hMLH1/hMSH2 genes may play important role in the incidence of HNPCC.
