Objective To explore the features of the cytochrome c oxidase subunit Ⅰ (COXⅠ) of Asian black bear Sichuan subspecies. Methods Primers were designed according published gene sequences of other bear species. A DNA sequence was amplified by PCR from the bear Sichuan subspecies’s hair-follicle tissue total DNA, then the PCR product was sequenced. The results were analyzed and a forecast analysis was carried on. Results The amplified COXⅠ gene of Sichuan black bear was 1 605 bp and contained a 1545-nucleotide open reading frame encoding 514 amino acid residues. The overall base composition of COXⅠ gene is 26.9 %, 23.1%, 18.3 %, and 31.8 % respectively to A, C, G, and T. The start codon of the COXⅠ is ATG, while the termination codon TAA. The protein’s pI is 6.29 and weight is 57.2?10 3 . The similarity analysis and phylogenetic tree analysis indicated that Sichuan black bear has closer relationship to American black bear, but not to brown bear and polar bear. Among dogs, caws and rats, it is closer to the former one. Conclusion There are high similarities in the DNA sequence, protein amino acid sequence of Asian black bear Sichuan subspecies with other bear species, indicating a high conservativity of COXⅠ in these involved species.

Objective To use diagnosis related group (DRGs ) for the first time in overall evaluation of inpatient service performance evaluation of major diagnostic category (MDC)for all the Beijing municipal hospitals,and recommend how to strengthen Beijing municipal hospitals system in diagnosis and treatment ability of main diseases and improve inpateint service performance.Methods BJ-DRGs burster software was used to analyze the first page information of the medical records of cases discharged from all the Beijing municipal hospitals between 2012 and 2014 to determine the weight of each DRG,and based on such weight the related indicators of such hospitals and central hospitals in 2012, 2013,2014 were compared and analyzed.Results Improvements were found in such indices as diagnosis and treatment difficulty of 50% MDC,time efficiency of 81.8% MDC,cost efficiency of 77.3% MDC, and general capacity of 54.5% MDC for all Beijing municipal hospitals.In addition,the municipal hospitals were found superior to the central hospitals in such indices as cost efficiency of 68.2% MDC, and time efficiency of 59.1% MDC.On the other hand however,they were found inferior to the central hospitals in such indices as diagnosis and treatment difficulty of 72.7% MDC,and the comprehensive ability index of the two systems were found equivalent.Another finding was that there was no obvious improvement of the coverage of disease types at major tertiary hospitals in Beijing for the past three years.Municipal hospitals of greater contribution of MDC weight were highly consistent with the hospitals assigned with national key projects of disciplinary developments. Conclusion The comprehensive evaluation results of inpatient service performance of main diseases at Beijing’s municipal hospitals based on DRGs system,showed that the Beijing’s hospital authority had played an important role in improving inpatient service performance especially in reducing the burden of patients,improving the service efficiency through increasing government investment,optimizing service organization and implementation of performance management.But it also suggested that measures such as collectivize construction and management should be taken to improve municipal hospitals’linical specialty ability, improve the MDC diagnosis and treatment difficulty,and resume their functions of tertiary hospitals.

Professor Cai Wanru believes that in the stable phase of chronic obstructive pulmonary disease, "phlegm" and "stasis" are intertwined, with "phlegm" as the main component. Disease is manifested mostly in the lungs, spleen and kidney, and along with the duration of the disease, the patients are prone to "sputum", "stasis" and other pathological products, so that acute aggravating symptoms are often induced due to the transformation from "phlegm" to "stasis". The clinical manifestations are mainly the lack of righteousness, and various symptoms due to phlegm stagnation and blood stasis. Therefore, Professor Cai believes that the thought of "preventive treatment of disease" should be throughout the treatment of the disease. The thought is based on the principle of the relationships between the five internal organs. According to the characteristics of disease transmission, combined with the syndrome differentiation of physical constitution, the importance of strengthening the body resistance and nourishing the vigour was emphasized. In terms of the methods of treatment, methods such as nourishing the lungs and tonifying the spleen, warming the kidney and tonifying qi are often applied, so the prescription is flexible and the compatibility is rigorous. In terms of the control of symptoms and prevention of acute exacerbations, it has a significant effect. Therefore, the thought of "preventive treatment of disease" proposed by Professor Cai Wanru has a practical value in the clinical treatment of chronic obstructive pulmonary disease, which is worthy of promotion.

Objective:To evaluate the effect of general anesthesia on microelectrode recording (MER) during deep brain stimulation (DBS) of subthalamic nucleus (STN) in the patients with primary Parkinson′s disease (PD).Methods:Forty-four patients of both sexes with primary PD (duration of disease ≥ 5 yr and/or obvious symptom fluctuation), undergoing bilateral STN DBS from March 2008 to March 2018, aged<80 yr, were selected and divided into 2 groups by a random number table method: awake group ( n=26) and general anesthesia group ( n=18). In awake group, 0.5% ropivacaine was used for incision infiltration at skin incision.Patients in GA group received propofol and remifentanil by target-controlled infusion with Narcotrend to monitor the depth of anesthesia, and 0.5% ropivacaine was used for incision infiltration at skin incision.The total number of trajectories and length of STN were recorded during MER.Movement disorders were evaluated at 1 week before surgery and 6 months after surgery, and the improvement rate of dyskinesia was calculated.The postoperative anesthesia-, hardware- and stimulation-related complications were recorded. Results:There were no significant differences between the two groups in the total number of trajectories, length of STN and improvement rate of postoperative movement disorders ( P>0.05). Conclusion:General anesthesia does not affect the MER during STN DBS in the patients with primary PD.

Objective To investigate the association between the nutritional status and related factors in patients with Parkinson's disease (PD).Methods Seventy-two patients with PD (PD group) and 71 age-and sex-matched healthy controls (control group) were enrolled in this study from September 2014 to November 2017 at the First Affiliated Hospital of Sun Yat-sen University.Their serum nutritional indices,including serum albumin,prealbumin,transferrin,free fatty acid and retinol conjugated protein,were collected.The PD participants were interviewed and assessed using motor and non-motor scales,including Hoehn and Yahr stage,Movement Disorder Society-Unified Parkinson's Disease Rating Scale (MDS-UPDRS),Non-Motor Symptoms Questionnaire for Parkinson's Disease (NMSS),Mini-Mental State Examination (MMSE),Unified Dyskinesia Rating Scale (UDysRS) and 39-item Parkinson's Disease Questionnaire (PDQ-39).Their medication dosage was indicated by daily levodopa equivalent doses (LEDD).Body mass index (BMI) was used to determine their nutritional status,with abnormal nutritional status defined as BMI lower than 20 kg/m2.Results Levels of serum albumin (41.60 (40.28,43.98) g/L vs 44.00 (42.30,46.20) g/L,Z=4.500,P＜0.01),transferrin ((2.32±0.34) g/L vs (2.51±0.34) g/L,t=-3.305,P=0.001),and free fatty acid (418.00 (289.75,637.25) μmol/L vs 547.00 (386.00,699.00) μmol/L,Z=2.079,P=0.038) of the PD group were significantly lower than those of the control group.There was a significant negative correlation between serum albumin and MDS-UPDRS-Ⅱ score (r=-0.254,P=0.031),MDS-UPDRS-Ⅳ score (r=-0.256,P=0.030),years of dyskinesia (r=-0.240,P=0.043),years of motor fluctuation (r=-0.304,P=0.009) and LEDDs (r=-0.321,P=0.006).Disease duration was negatively correlated with serum albumin (r=-0.285,P=0.015) and transferrin (r=-0.275,P=0.019),and age (r=-0.252,P=0.032) was negatively correlated with prealbumin.The forward binary Logistic regression model indicated that abnormal nutritional status was closely associated with rigidity (OR=1.171,95％CI 1.013-1.354,P=0.032),akinesia (OR=1.070,95％CI 1.000-1.144,P=0.048),UDysRS score (OR=1.051,95％CI 1.004-1.099,P=0.032),MDS-UPDRS-Ⅳ score (OR=1.177,95％CI 1.018-1.360,P=0.027) and MMSE score (OR=0.821,95％CI 0.678-0.994,P=0.043),but not correlated with tremor and axial symptoms.Compared with PD patients with abnormal nutritional status,PD patients with normal nutritional status had higher MMSE scores (28.00 (27.00,29.00) vs 28.00 (25.00,28.00),Z=-2.060,P=0.039),lower rigidity (9.60±3.83 vs 12.00±4.29,t=-2.264,P=0.027),akinesia (19.98 ± 8.00 vs 24.42:±:8.06,t=-2.071,P=0.042) and MDS-UPDRS-Ⅳ scores (8.00 (5.00,11.00) vs 10.00 (9.00,13.00),Z=2.642,P=0.008).Conclusions PD patients tend to have a lower serum nutritional indices.PD patients with lower levels of serum nutritional indices are characterized by more severe motor complication,longer disease duration,older age and higher LEDD.PD patients with abnormal nutritional status have worse cognition and more severe motor symptoms (rigidity,akinesia and motor complication).

Objective: To explore effects of histone deacetylase inhibitor Belinostat on the immunologic function of dendritic cells (DC) and its possible mechanism. Methods: Cultured mouse bone marrow-derived DC from C57BL/6 mouse in vitro. The experiments were divided into 0, 50, 100 nmol/L Belinostat + immature DC (imDC) group, and 0, 50, 100 nmol/L Belinostat mature DC (mDC). The changes of the ultrastructure of DC were observed by transmission electron microscope (TEM). Immunophenotype and CCR7 expression rate were detected by FCM, and the migration rate was observed by chemotaxis assay. The proliferation of lymphocytes stimulated by different DC was detected by mixed lymphocyte culture reaction. The cytokines in the culture supernatant, including TNF-α, IL-12 and IL-10, were examined by ELISA. RQ-PCR was used to examine the relative expression of mRNA in RelB. Results: Successful cultured and identified the qualified imDC and mDC. Belinostat decreased the expression of CCR7 on imDC [(25.82±7.25)% vs (50.44±5.61)% and (18.71±2.00)% vs (50.44±5.61)%], meanwhile increased the rate on mDC [(71.14±1.96)% vs (64.90±1.47)%]. Chemotaxis assay showed that the migration rate of Belinostat+imDC and Belinostat+mDC group were both decreased, but the difference in imDC was not significant. T lymphocyte proliferation rate stimulated by 100 nmol/L Belinostat+imDC group was lower than imDC group in condition irritation cell∶reaction cell=1∶2 [(227.09±13.49)% vs (309.49±53.69)%]. Belinostat significantly suppressed the secretion of cytokines TNF-α, IL-12 and IL-10 (all P<0.01). The relative expression of mRNA in RelB was slightly decreased in Belinostat+imDC and Belinostat+mDC group (all P<0.05). Conclusion Belinostat could effectly suppress DC maturation and regulate immune tolerance of DC, which may be due to the down-regulation of mRNA level of RelB in DC.

Objective To examine the effect of posterior reduction in atlantoaxial dislocation (AAD) associated with basilar invagination(BI) using Xuanwu occipital?cervical fusion system in single stage. Methods Thirty?seven AAD accompanied with BI cases treated at Department of Neurosurgery, Xuanwu Hospital,Capital Medical Universiy and the Second Hospital of Hebei Medical University were retrospective analyzed. There were 15 males and 22 females with age of (42.3 ± 12.3)years (range: 18-69 years). All the cases had congenital osseous abnormalities, such as assimilation of atlas and abnormal cervical fusion. Anterior tissue was released through posterior route followed by cage implantation into facet joint and occipital?cervical fixation with cantilever technique. The clinical results were evaluated using Japanese Orthopedic Association scale(JOA) and the main radiological measurements including anterior atlantodental interval (ADI),the distance of odontoid tip above Chamberlain line,clivus?canal angle(CCA) and the length of syrinx were collected. The preoperative and postoperative JOA score and radiological measurements were compared by paired t?test. Results The mean JOA score of the patients increased from 10.5 to 14.4 at the one?year follow?up(t=14.3,P=0.00).Complete reduction of AAD and BI was achieved in 34 patients.The mean clivus?canal angle improved from (118.0±6.5)degrees preoperative to (143.7±5.0)degrees postoperative(t=6.2,P=0.00).Shrinkage of the syrinx was observed 1 week after surgery in 24 patients,and 6 months in 31 patients.Twenty?eight patients achieved bone fusion 6 months after surgery. All the patients achieved bone fusion 12 months after surgery. One?side vertebral artery occlusion was diagnosed in 1 case postoperatively for transient dizziness,and relieved in 2 weeks.Two patients developed moderate neck pain after surgery, and relieved in 1 month. No implant failure, spacer subsidence or infection was observed. Conclusions The treatment of AAD associated with BI using Xuanwu occipital?cervical fusion system from posterior approach in single stage is effective and safe. Cage implantation intraarticularly and fixation with cantilever technique achieve complete reduction in most cases.
