The microinjection of brain nuclei and potassium iontophresis induced tail flick were used to investigate the effect of injecting oxytocin (OT) or anti-oxytocin serum (AOTS) into locus ceruleus (LC) on the pain threshold (PT) and morphine analgesia. The result showed that OT injection into LC could enhance PT, while ATOS injection could reduce PT. The OT injection could strengthen morphine analgesia, but AOTS injection could antagonize this action. These results suggest that the OT analgesia and OT-enhanced morphine analgesia were related with the locus ceruleus.

Objective To investigate the prevalence and clinical characteristics of Sj?gren′s syndrome-interstitial lung disease (SS-ILD). Methods 136 patients with SS were studied. Anti-SSA and Anti-SSB antibodies were measured by Western blot. The inpatients had chest X ray, chest HRCT and pulmonary function examined. Results ①pSS-ILD patients with postive anti-SSA antibody were proned to have interstitial lung disease and the ILD were more severe. ②HRCT showed that sSS-ILD were more severe than that of pSS-ILD. ③Lung capacity of pSS-ILD decreased more frequently than sSS-ILD. sSS-ILD mainly had venti-latory function abnormalities. The lung function impairment of both were dominated by small airways dysfunction and decrease of TLCO. Conclusion SS patients should be examined by HRCT and lung function tests should be performed in the course of the disease to find out and treat ILD.

AIM: To establish a quality control method of analysing Lajiao Fengshi Plaster qualitatively and quantitatively. METHODS: Capsaicin was identificated by TLC and menthol,borneol were determinated by GC Lajiao Fengshi Plaster,silica gel as plate,ligarine(60～90?C)-acetoacetate(3(∶)2) as mobile phase,0.5% solution of dichloroquinonechlorimide R in methanol R.as chromogenic agent to identificate capsaicin.The internal standard of GC,naphthalene was employed.10% PEG-20M as the stationary phase,column temperature at 150(?C,) and FID as the detector to determine methol and borneol. RESULTS: There were the same spot corresponding in colour and position sample and reference capsaicin,but negative control had not such colour spot in the same plate of TLC.Menthol,borneol and naphthalene had been separated well under the chromatographic condition.The average recovery of menthol,borneol were 97.44%(RSD=0.93%),98.09%(RSD=1.26%),respectively. CONCLUSION: The method is sensitive,accurate and reproducible and can be used to control the quality of Lajiao Fengshi Plaster.

METHODS:A C_(18) column was used,methyl alcohol-water(80∶20) was used as a mobile phase and the wavelength of UV detector was set at 290 nm. RESULTS:The linearity of this method was good with the average recovery of 97.9%,RSD was 0.74%(n=5). CONCLUSION:The methed is simple,reliable,sensitivity,and with good reproducibility.It can be used in quality control of Weitengning Tablets.

Objective To study the characteristics of granulomatosis with polyangiitis (GPA) accompanied by pneumothorax.Methods We described a case of GPA accompanied by hydropneumothorax who was successfully treated.Relevant literature was also reviewed.Results A total of 25 cases were identified,consisting of 18 males and 7 females [the average age was (44±16)(16-70) years old].The time from disease onset to pneumothorax was 26±51 (0.83-216) weeks.Pneumothorax,hydropneumothorax,pyopneumothorax and hemopneumothorax occurred in 11,5,8 and 1 respectively.Nodules or excavated nodules on chest radiography or CT were seen in 22 cases.Erythrocyte sedimentation rate (ESR) and C reactive protein (CRP) were elevated in all cases.Sixteen cases received glucocorticoid and immunosuppressive agents treatment.Sixteen cases received drainage and 7 received open operation.Pseudomonas aeruginosa was the most commonmicrobiology findings.Granulomatosis with active vasculitis,bronchopleural fistula,pleural bleb with intensefibrosis,rupture of subpleural nodule were seen on lung biopsy or autopsy.Nine cases died of infections,respiratory failure,sepsis and respiratory arrest.Conclusion Pneumothorax in GPA can be caused by multiple factors such as rupture of subpleural nodule and with high mortality.Patients always died of infections and respiratory failure.Regular treatment of the underlying disease,apply sensitive antibiotics for infection and reasonable surgical intervention should be considered.

Objective To investigate the effect of hepatopoietin Cn(HPPCn) on liver stem cells.Methods In this study, WB-F344 cell line was used, and MTT and flow cytometry assay were conducted to determine cell proliferation and apoptosis.Transwell assay was used to test the migration of WB-F344 cells.A 2AAF-partial hepatectomy(PH) mouse model was used to observe the effect of HPPCn on liver stem cell proliferation in vivo.Results HPPCn enhanced WB-F344 cell proliferation and migration and activated the SphK1, Erk and Stat3 signal pathways.The analysis of the 2AAF-PH mouse model showed that oval cells in the experimental group far outnumbered those in control and the regeneration of the liver was improved post PH.Conclusion HPPCn can increase the liver stem cell proliferation and survival while promoting the regenenation of the liver by augmenting oval cell proliferation.

Objective To explore the surgical method and effects of posterior expansive open-door laminoplasty extended to C1,2 levels.Methods 16 cervical spinal stenosis patients with cervical myelopathy were posterior cervical surgery in our hospital from February 2013 to September 2015,including 11 males and 5 females;aged 51-76,average 62.8.4 cases merged C1spinal stenosis,the line which operated by C1～7 spinal posterior open-door expansion of the forming with mini titanium fixation;12 cases merged C2 spinal stenosis,which had the operation of C2～7 posterior open-door laminoplasty with Micro Titanium fixation plate.According to the patient imaging data to assess the stability of the cervical spine,and spinal cord compression fixation position before and after their surgery evaluated;the preoperative and postoperative pain using visual analog scale (VAS);application Japanese Orthopaedic Association (JOA) score spinal cord score was used to evaluated spinal cord function,and calculates the rate of improvement of neurological function;surgery patients before and after application Frankel grading was used to evaluate neurological function.Results All patients were followed up,for an average of 11.58 months (2-33 months).16 patients showed no loosening,fracture fixation and related complications,C1,2 showed no instability;cerebrospinal fluid surrounding the spinal cord with in the C1-7 range of the signal on MRI T2WI showed continuous recovery;preoperative VAS score was 6.7 points,postoperative VAS score was 1.8 points;the first 16 cases of patients with preoperative JOA score average (8.3± 1.6) points,postoperative JOA score was (14.6±1.4) points,postoperative neurological improvement rate was 91.6％;Frankel grade C before operation and grade E in postoperation;postoperative follow-up neurological improvement rate excellent 7 cases,good 7 cases,general 2 cases.Conclusion Treatment of cervical spinal stenosis combined with cervical myelopathy may use a C 1-7 posterior spinal expand within the single door molding fixation with mini titanium plate,which can release the compression of the cervical spinal cord nerve and reconstruct a stable structure of posterior of cervical spine.
