Objective To summarize the various acute abdomen manifestation of systemic lupus erythematosus (SLE) and their diagnosis and treatment.Methods Twenty SLE patients with AA were analysed and 35 year′s literature was reviewed.Results Most AA were of active SLE (70%),others were of non SLE related disease (30%).Cause of these cases was diversified,which often lead to misdiagnosis.Making correct diagnosis as early as possible was the key point to improve the patient′s survival rate.Conclusion SLE with AA indicates a critical condition.Investigating the cause of AA and working out appropriate treatment measures are most important.

AIM and METHODS: To detect the changes of amyloid protein (?-AP) and polypeptide growth factor levels and study their role in the possible pathogenesis of Alzheimers disease (AD) and vascular dementia (VD). We detected serum ?-AP, transforming growth factor- ?(TGF-?) and insulin-like growth factor (IGF-Ⅱ) levels by radio immunoassay in 8 patients with AD,15 patients with VD and 63 patients with ischemic cerebrovascular disease(ICVD) and 38 cases healthy volunteers. RESULTS: In AD and VD groups, serum ?-AP, TGF-? and IGF-Ⅱ were significantly higher than that in ICVD and control group; Serum ?- AP,TGF-? and IGF-Ⅱ contents in ICVD group were obviously higher than that in normal control, the highest increase occurred in sequel of cerebral infarction(SCI) and vertebrobasislar ischemia(VBI) groups. There are positive correlation among ?- AP, TGF-? and IGF-Ⅱ in AD and VD groups.CONCLUSION: ①?- AP is a risk factor in the pathogenesis of AD and VD. ② TGF- ? and IGF-Ⅱ play roles in the neurotoxin effect that lead to dementia. ③ ?-AP plays a important role in formation of senile plaque.

OBJECTIVETo investigate the skill and evaluate the accuracy for application of guide combined with probing the internal wall of pedicle screw trajectory for subaxial cervical pedicle screw placement.

METHODSSubaxial cervical pedicle screw was inserted in 11 patients by the guide combined with probing the internal wall of pedicle screw trajectory from January 2014 to October 2016, including 7 males and 4 females with an average age of 48.1 years(ranged 32 to 63 years). There were 4 cases with cervical spondylotic myelopathy, 4 with fracture and dislocation of cervical vertebrae, 1 with cervical cord injury without fracture and dislocation, and 2 with atlantoaxialfracture and dislocation. The target pedicle's diameter, optimal entry point, sagittal angle and cross-sectional angle were measured by CT before operation. During operation, the pedicle screw inserted angle was controlled by a guide with a self-designed protractor and probed the internal wall of pedicle screw trajectory as medial safety margin of insertion screw. The accuracy of cervical pedicle screw was evaluated by CT with classification of four grades and assessed whether there was injury of spine cord or vertebral artery postoperatively.

RESULTSSeventy-one cervical pedicle screws were placed among 11 patients, and no one had been found with clinical manifestations of injury of spine cord (or nerve root) or vertebral artery after operation. According to postoperative CT scan for evaluating the grade of screw position, 52 screws were in grade 0, 13 in grade 1, 4 in grade 2, 2 in grade 3, and 91% (65/71) located in good position. In total, 6 screws were incorreted in placement, and 4 cases of them broke medial wall and 2 cases broke lateral wall.

CONCLUSIONSThe method of probing the internal wall of pedicle screw trajectory for subaxial cervical pedicle screw placement is safe and reliable, but the studying curve is long. Probing the internal wall of pedicle screw trajectory and controlling the insertion angle by guide with a protractor are key points of this technology.

OBJECTIVE： To establish a fluorescence identification method of the microscopic characteristics for Plantagin Semen and its adulterants， and to provide technical support for the market supervision and inspection of TCM decoction pieces. METHODS： Under visible and ultraviolet light， comparative study and identification of the Plantagin Semen （seeds of Platago asiatica L. and Platago depressa Willd.） and its adulterants as seeds of Platago major L.， fruits of Schizonepeta tenuifolia Briq.， seeds of Codonopsis pilosula （Franch.） Nannf， seeds （peeled） of Kochia scoparia （L.） Schrad.， fruits of Bupleurum chinense DC. were carried out by means of stereoscopic fluorescence microscopy from aspects of overall surface characteristics， umbilicus characteristics and section characteristics. RESULTS： Under visible light， the surface texture of Plantagin Semen was wavy stripe or fine wrinkle， while the adulterants were wavy stripe， longitudinal edge or texture was not obvious. The umbilicus of Plantagin Semen was located in the center of the ventral surface， while that of adulterants were located at one end except for P. major. In the section of Plantagin Semen， there were obvious direct embryos， in which the adulterants were small or circular embryos except for P. major. Under ultraviolet light， P. asiatica had obvious wavy stripes in surface， orange and light blue-green fluorescence； P. depressa had grid-shaped wrinkles and gray-blue and gray-brown fluorescence； the umbilical fluorescence of Plantagin Semen was strong， and the fluorescence of the adulterants was weak except for S. tenuifolia. There were obvious differences in fluorescence color， embryo size and distribution between the section of Plantagin Semen and adulterants. CONCLUSIONS： The stereoscopic fluorescence microscopy is effect and accurate for the identification of Plantagin Semen.
