Since the instability of the spine caused by trauma,tumor,tuberculosis,deformity cor-rection and other reasons requires reconstruction,many scholars have conducted a large number of thorough researches,but the treatment options for unstable cervical spine still plague the clinicians.Considering the factors of stability and safety,more and more clinicians choose cervical pedicle screw placement as the treatment for spinal instability.In this work,the most common methods and the latest technologies of cervi-cal pedicle screw placement at home and abroad are summarized and reviewed.It provides references for clinical practices and presents the significance of high-tech assisted screw placement in the future.

ObjectiveTo investigate advantage and disadvantage of different rehabilitation therapies used for cerebral palsy (CP) children complicated with epilepsy (EP).Methods140 CP children complicated with EP screened from 1402 CP cases, were analyzed for CP and EP types, MRI or CT, brain stem auditory evoked potentials (BAEP). All cases were treated with anti-epilepsy drugs (AEDs). Different rehabilitation therapies, including electrotherapeutic modalities, acupuncture, point injection, cerebroprotein hydrolysate injection, manual therapy, functional training, Chinese herb braising therapy, and cattle encephalon glycoside and ignotin injection were assessed.ResultsIn all 140 cases, a majority of EP types were myoclonic seizure and west syndrome, CP type was spasticity. Abnormality showed in MRI or CT (98%) and BAEP (90%). AEDs were effective for all 140 cases. Electrotherapeutic modalities, acupuncture, point injection, and cerebroprotein hydrolysate injection could make EP severely, but manual therapy, functional training, Chinese herb braising therapy, cattle encephalon glycoside and ignotin injection had no adverse effects on EP cases.ConclusionThe principles of rehabilitation treatment for the CP children complicated with EP are taking AEDs early and in a long term, avoiding electrotherapeutic modalities, acupuncture, point injection, and cerebroprotein hydrolysate injection, using manual therapy, functional training, Chinese herb braising therapy, and cattle encephalon glycoside and ignotin injection.

Objective To investigate the effects of ropivavaine on gamma -aminobutyric acid(GABA)-activated membrane cur-rents in isolated dorsal root ganglion(DRG) neurons of the rats with ischiadic nerve chronic constriction injury (CCI) and to discuss the possible analgesia mechanism of ropivacaine .Methods The whole-cell patch clamp technique was used to record and compare the changes of GABA receptor activation currents of acute isolated DRG neurons after 30 s of ropivacaine preperfusion in the oper-ating side and the operative opposite side of the CCI model rats and the sham-operation group .Results (1)Compared with the oper-ative opposite side ,the sham-operation group and the control group ,the thermal withdrawal latency in the operative side group of the CCI model rats was notablely shortened(P<0 .05);(2)the amplitude of GABA-activated currents with different concentration GABA(0 .1-1 000μmol/L) in the operative opposite side group of the CCI operation was significantly greater than that of the op-erative side group and the sham-opeartion group ;(3)DRG neurons after ropivacaine preperfusion (0 .1-1 000μmol /L) showed va-rying degrees of enhancement effect on the 100 μmol/L GABA-activated currents ,the enhancement amplitude in the CCI operative opposite side group was significantly greater than that in the operative side group and the sham-operation group ;(4)The dose-re-sponse curve of DRG neurons GABA (0 .1-1 000μmol/L) activated current in the operative side group of the CCI rats after ropiva-caine pre-perfusion (100 μmol/L) was shifted to the left ,the difference between two EC50 had no statistical significance (P>0 .05) .Conclusion Ropivacaine has the enhancement effect on GABA activated currents in the DRG neurons of the CCI model rats , which could be one of reasons for ropivacaine producing the anesthetic and analgesic effect .

Objective To observe the effect of Danzhi Jiangtang Capsules(DJC) on serum interleukin-18 (IL-18),cystatin C (CysC) and relative biochemical indexes in patients with early diabetic kidney disease(DKD),and to explore its protective action on the kidney.Methods Sixty-two hospitalized patients with early diabetic nephropathy (period 11-Ⅲ) in Endocrinology Department of the First Affiliated Hospital of Anhui University of Traditional Chinese Medicine were divided into western medicine group and DJC group,31 cases in each group.The patients in western medicine group received conventional hypoglycemic drugs,and DJC group received DJC based on the treatment for the western medicine group.Before and after treatment,we observed the levels of serum IL-18,CysC,fasting plasma glucose (FPG),2-hour postprandial glucose (2hPG),glycosylated hemoglobin (HbA1c),serum creatinine (SCr),blood urea nitrogen (BUN),microalbumin (mAlb),urinary albumin /creatinine ratio (UACR),and estimated glomerular filtration rate (eGFR).Results The total effective rate was 90.0％ in DJC group and 76.7％ in the western medicine group,there being significant difference between the two groups(P ＜ 0.05).After treatment,the main traditional Chinese medical syndrome scores of DJC group were significantly lower than those before treatment,and the improvement was better than that of the western medicine group (P ＜ 0.05 or P ＜ 0.01).After treatment,the serum levels of IL-18,CysC,2hPG,SCr,BUN,mAlb,UACR in the two groups were significantly lower than those before treatment (P ＜ 0.05 or P ＜ 0.01),while eGFR level was higher than that before treatment (P ＜ 0.05 or P ＜ 0.01),and the improvement effect (except for BUN) in the DJC group was superior to that in the western medicine group(P ＜ 0.01).DJC had an effect on lowering the FPG and HbA1c (P ＜ 0.05 or P ＜ 0.01 compared with those before treatment),and the western medicine had no obvious effect on the two indexes (P ＞ 0.05).The results of Spearman correlation analysis showed that IL-18 was correlated with CysC,IL-18 and CysC were correlated with HbA1c,mALB and uACR.Conclusion DJC can protect renal function of patients with early diabetic nephropathy.

BACKGROUND:With the improvement of cervical posterior surgical techniques, lateral mass screw fixation technology has been widely used in the reconstruction surgery of the cervical spine for stability. However, currently, the finite element study on the lateral mass screw fixation reconstruction of the cervical spine is rare. OBJECTIVE:To establish a fine normal lower cervical spine (C3-C7 ) three-dimensional finite element model and a reconstructed finite element model with three-segment laminectomy with lateral mass screw fixation. Then, to do an initial biomechanical analysis of the lateral mass screw fixation reconstructed lower cervical finite element model. METHODS:We col ected a normal female volunteer aged 30 years old to do CT scan for the whole cervical spine. The Dicom data were obtained. Then, the CT scanning images were dealt with software Mimics 10.01, Geomagic Studio 12.0, Solidworks2012, HyperMesh 10.1 and Abaqus 6.12 software to build the normal lower cervical spine (C 3-C7 ) finite element model, the laminectomy finite element model and the rebuilt finite element model. At last, we analyzed the stress changes of reconstructed models under the state of flexion, extension, lateral bending and rotational motion. RESULTS AND CONCLUSION:The lower cervical spine finite element model contained 503 911 elements and 93 390 nodes with a fine realistic appearance. It successful y passed the validation. The surgical procedure was completed in the software, and the lateral mass screw fixation reconstruction finite element model has been established. Lateral mass screw fixation system provides good stability for the postoperative finite element model. The activity of rebuilt finite element model is much lower than the normal finite element model. In the extension condition, the stress of lateral mass screw fixation system becomes strong.

Dihydroartemisinin is an important derivative of artemisinin. We used dihydroartemisinin as the starting material, through esterification, amination and acylation, a series of novel piperazine-sulfonamide contained dihydroartemisinin derivatives were firstly synthesized and their chemical structures were confirmed by IR, 1H NMR, 13C NMR and HR-MS. X-diffraction was used to determine the final configuration of the compound 3c. And the in vitro anti-HeLa activities of compounds 3 were analyzed with CCK-8 method. The preliminary bioassay test shows that compound 3 showed the best inhibition activities against HeLa with IC50 values of 0.14 micromol x L(-1).

A yeast strain KM12 , which can convert conjugated anthraquinone of rhub arb to free anthraquinone , was screened. And it is identified as Kluyveromyces marxianus by 26S rDNA. The percentage of free an-thraquinone in total anthraquinone of rhub arb as an indicator was used to investigate the effect of culture medium component and fermentation processing conditions, such as seed age, fermentation time and liquid volume on con-version of conjugated anthraquinone by KM12. The optimal fermentation medium was determined by orthogonal test L9(43) and the composition (%) is yeast extract 1, glucose 2, and rhubarb 2. The 5% (V/V) of the seed culture inoculated 36-48 h was inoculumed to fermentation medium in shake flask to ferment at 30℃, 200 r?min-1 for 4 days. TLC analysis showed most of conjugated anthraquinone decomposed or converted into free anthraquinone in fermented rhub arb . It was concluded that the side effect of severe diarrhea caused by Chinese medicine rhub arb can be alleviated through fermentation processing by KM12 strain .
