ABSTRACT

OBJECTIVE@#To observe the effect of Tongdu Tiaoshen (promoting the circulation of the governor vessel and regulating the spirit) electroacupuncture (EA) pretreatment on pyroptosis mediated by peroxisome proliferators-activated receptor γ (PPARγ) of the cerebral cortex in rats with cerebral ischemia reperfusion injury (CIRI) and explore the potential mechanism of EA for the prevention and treatment of CIRI.@*METHODS@#A total of 110 clean-grade male SD rats were randomly divided into a sham-operation group, a model group, an EA group, an EA + inhibitor group and an agonist group, 22 rats in each group. In the EA group, before modeling, EA was applied to "Baihui" (GV 20), "Fengfu" (GV 16) and "Dazhui" (GV 14), with disperse-dense wave, 2 Hz/5 Hz in frequency, 1 to 2 mA in intensity, lasting 20 min; once a day, consecutively for 7 days. On the base of the intervention as the EA group, on the day 7, the intraperitoneal injection with the PPARγ inhibitor, GW9662 (10 mg/kg) was delivered in the EA + inhibitor group. In the agonist group, on the day 7, the PPARγ agonist, pioglitazone hydrochloride (10 mg/kg) was injected intraperitoneally. At the end of intervention, except the sham-operation group, the modified thread embolization method was adopted to establish the right CIRI model in the rats of the other groups. Using the score of the modified neurological severity score (mNSS), the neurological defect condition of rats was evaluated. TTC staining was adopted to detect the relative cerebral infarction volume of rat, TUNEL staining was used to detect apoptosis of cerebral cortical nerve cells and the transmission electron microscope was used to observe pyroptosis of cerebral cortical neural cells. The positive expression of PPARγ and nucleotide-binding to oligomerization domain-like receptor protein 3 (NLRP3) in the cerebral cortex was detected with the immunofluorescence staining. The protein expression of PPARγ, NLRP3, cysteinyl aspartate specific protease-1 (caspase-1), gasdermin D (GSDMD) and GSDMD-N terminal (GSDMD-N) in the cerebral cortex was detected with Western blot. Using the quantitative real-time fluorescence-PCR, the mRNA expression of PPARγ, NLRP3, caspase-1 and GSDMD of the cerebral cortex was detected. The contents of interleukin (IL)-1β and IL-18 in the cerebral cortex of rats were determined by ELISA.@*RESULTS@#Compared with the sham-operation group, the mNSS, the relative cerebral infarction volume and the TUNEL positive cells rate were increased (P<0.01), pyroptosis was severe, the protein and mRNA expression levels of PPARγ, NLRP3, caspase-1 and GSDMD were elevated (P<0.01); and the protein expression of GSDMD-N and contents of IL-1β and IL-18 were increased (P<0.01) in the model group. When compared with the model group, the mNSS, the relative cerebral infarction volume and the TUNEL positive cells rate were decreased (P<0.01), pyroptosis was alleviated, the protein and mRNA expression levels of PPARγ were increased (P<0.01), the protein and mRNA expression levels of NLRP3, caspase-1 and GSDMD were decreased (P<0.01), the protein expression of GSDMD-N was reduced (P<0.01); and the contents of IL-1β and IL-18 were lower (P<0.01) in the EA group and the agonist group; while, in the EA + inhibitor group, the protein expression of PPARγ was increased (P<0.01), the protein and mRNA expression levels of NLRP3 and GSDMD were decreased (P<0.01, P<0.05), the mRNA expression of caspase-1 was reduced (P<0.01); and the contents of IL-1β and IL-18 were lower (P<0.01). When compared with the EA + inhibitor group, the mNSS, the relative cerebral infarction volume and the TUNEL positive cells rate were decreased (P<0.05, P<0.01), pyroptosis was alleviated, the protein and mRNA expression levels of PPARγ were increased (P<0.01), the protein and mRNA expression levels of NLRP3, caspase-1 and GSDMD were decreased (P<0.01), the protein expression of GSDMD-N was reduced (P<0.01); and the contents of IL-1β and IL-18 were declined (P<0.01) in the EA group. Compared with the agonist group, in the EA group, the relative cerebral infarction volume and the TUNEL positive cells rate were increased (P<0.05, P<0.01), the mRNA expression of PPARγ was decreased (P<0.01) and the protein expression of GSDMD-N was elevated (P<0.05); and the contents of IL-1β and IL-18 were higher (P<0.01).@*CONCLUSION@#Tongdu Tiaoshen EA pretreatment can attenuate the neurological impairment in the rats with CIRI, and the underlying mechanism is related to the up-regulation of PPARγ inducing the inhibition of NLRP3 in the cerebral cortex of rats so that pyroptosis is affected.

ABSTRACT

Professor HAN Wei 's clinical experience of acupuncture and moxibustion with Tongyang Xingshen (promoting yang and regaining consciousness) for adolescent depressive disorder is introduced. It is believed that the internal causes of adolescent depressive disorder are mostly emotional and physical factors, while the external causes are mainly social factors, and yang-qi stagnation and emotional disorder are the key pathogenesis. The key of acupuncture and moxibustion with Tongyang Xingshen is warming and regulating the governor vessel. The governor vessel acupoints at head, neck and back are selected. At head, Baihui (GV 20) and Yintang (GV 24+) are selected; at neck, Fengfu (GV 16) and Dazhui (GV 14) are selected; at back, Taodao (GV 13), Shenzhu (GV 12), Shendao (GV 11), Zhiyang (GV 9) and Jinsuo (GV 8) are selected. The combination of disease differentiation and syndrome differentiation should be highly valued, and the moxibustion with Tongyang and acupuncture with Xingshen should be used simultaneously, and the strong stimulation is suggested.

ABSTRACT

OBJECTIVE@#To observe the clinical therapeutic effect of Tongdu Tiaoshen acupuncture combined with carotid endarterectomy (CEA) and simple CEA on carotid artery stenosis (CAS).@*METHODS@#A total of 60 patients with CAS were randomized into an observation group (30 cases, 2 cases dropped off) and a control group (30 cases, 3 cases dropped off). Both groups were treated with eversion CEA (eCEA). The conventional treatment of internal medicine and antiplatelet drugs i.e. aspirin enteric-coated tablet and clopidogrel hydrogen sulfate tablet were given in the control group for 4 weeks. On the basis of the treatment in the control group, Tongdu Tiaoshen acupuncture was applied at Baihui (GV 20), Fengfu (GV 16), Yamen (GV 15), cervical Jiaji (EX-B 2), Dazhui (GV 14), etc. in the observation group, once a day, 1-day rest was taken after 6-day treatment, 2 weeks were as one course and totally 2 courses were required. The carotid intima-media thickness (IMT) before and after treatment was detected by ultrasonic diagnostic apparatus, the TCM symptom score was compared before and after treatment and in the follow-up of 6 months after treatment, the clinical efficacy was evaluated in the two groups. The occurrence of endpoints within 1 year was recorded.@*RESULTS@#After treatment, the carotid IMT and TCM symptom scores were decreased compared before treatment in the both groups (P<0.05), and the changes in the observation group were greater than the control group (P<0.05). In the follow-up, the TCM symptom scores were decreased compared before treatment in the both groups (P<0.05). The total effective rate was 96.4% (27/28) in the observation group, which was superior to 88.9% (24/27) in the control group (P<0.05). There were 1 case of stoke in the observation group and 2 cases of stroke in the control group within 1-year follow-up, and there was no significant difference in the number of endpoints between the two groups within 1 year (P>0.05).@*CONCLUSION@#Tongdu Tiaoshen acupuncture combined with CEA can effectively reduce the IMT in patients with CAS, improve the TCM symptom score, the efficacy is superior to simple CEA treatment.

ABSTRACT

Beads, a novel drug delivery system self-assembled by cyclodextrins (CDs) and oil, has potential applications in the solidification of oil drugs and improving the bioavailability of lipid-soluble drugs. However, very few researches were dedicated to the mechanism of beads formation. In this study, three-dimensional structures of beads were visualized and investigated using synchrotron radiation X-ray microcomputed tomography (SR-μCT). The structural changes of beads attributed by drying process were analyzed and confirmed via visualization results of SR-μCT. Productively, it was proposed that Pickering emulsion droplets obtained during beads formation process were spatially localized orderly. Moreover, the effects of loading lipid soluble drug, namely, vitamin K1, on the structural changes of beads were also analyzed. It is well known that the surface tension of oil phase could be changed by the addition of lipid soluble constituents. It was reasonable that the three-dimensional structure of beads might be altered during the drug loading of vitamin K1 into the beads. However, although the morphologies of beads were changed to some extent, the ordered Pickering emulsion droplets during the process of beads formation was successfully illustrated based on the SR-μCT results. Conclusively, according to the three-dimensional structural analysis of the beads, this study revealed the organized architecture for Pickering emulsion droplet assembly and beads formation in cyclodextrin semi-inclusion complex, which significantly complements the formation mechanism of beads, and provides a structural basis for the further study of beads.

ABSTRACT

<p><b>OBJECTIVE</b>To assess the clinical efficacy of acupuncture pretreatment for the prevention of stroke based on promoting the circulation of the Governor Vessel and regulating mentality, and explore its effect mechanism.</p><p><b>METHODS</b>Seventy cases of transient ischemic attack (TIA) were randomized into an acupuncture group (35 cases) and a western medicine group (35 cases). In the acupuncture group, acupuncture therapy of promoting the circulation of the Governor Vessel and regulating mentality was applied at Yaoyangguan (GV 3), Mingmen (GV 4), Zhiyang (GV 9), Shenzhu (GV 12), Dazhui (GV 14), Yamen (GV 15), Fengfu (GV 16), Baihui (GV 20) and Neck-Jiaji (EX-B 2). Acupuncture was given 6 times a week, at the interval of one day between two weeks. Totally, 21 days of treatment were taken as a session. In the western medicine group, aspirin enteric coated tablets were prescribed, 25 mg/tablet, 100 mg/day, once a night for oral administration, and 21 days of medication were taken as 1 session. There were 3 days at the interval between two sessions in each group and totally 2 sessions were required. Transcranial Doppler (TCD) was adopted before treatment and in two sessions of treatment to observe, mean flow velocity (Vm) of middle cerebral artery (MCA), vertebral artery (VA), basilar arte ry (BA) and pulsatility index (PI). The standard of the efficacy assessment of stroke aura was taken as the main efficacy index in the assessment of theraputic effect, the adverse reaction was observed.</p><p><b>RESULTS</b>1In TIA, MCA blood flow was accelerated in internal carotid system, and BA blood flow was accelerated in vertebral-basilar artery system. The treatments in the two groups enabled the blood flow in the responsible blood vessels slow down and the results in the acupuncture group L(60. 54+/-11.76)cm/s, (36. 17+/-8. 65)cm/s] were better than those in the western medicine group [(72. 34+/-9. 15)cm/s,(65. 23 +/-8. 99)cm/s] (P<O. 05). 2The results of clinical efficacy and adverse reactions in the acupuncture group [96. 77% (30/31),6. 45% (2/31)] were superior to the western medicine group [75. 76%(25/33),45. 46%(15/33)] (both P<0. 05). 3Concerning to the recurrence of disease at the different period after treatment, the case number of cerebral infarction was not different significantly between the two groups (P>0. 05).</p><p><b>CONCLUSION</b>Acupuncture intervention based on promoting the circulation of the Governor Vessel and regulating mentality achieves the superior efficacy on TIA and less adverse reactions as compared with aspirin. The effect mechanism is related potentially to the improvement of cerebral vascular hemodynamic.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the change of lymphocyte subsets before and after chemotherapy in colorectal carcinoma patients.</p><p><b>METHODS</b>Twenty-one peripheral blood lymphocyte subsets from 62 colorectal carcinoma patients before and after FOLFOX4(including oxaliplatin, 5-fluorouracil and leucovorin) , FOLFRI(including irinotecan, 5-fluorouracil and leucovorin) , or XELOX(including oxaliplatin and capecitabine) regimen chemotherapy were examined by flow cytometry.The differences of these lymphocyte subsets were analyzed.</p><p><b>RESULTS</b>After chemotherapy, the percentages of CD3(+), CD3(+)CD8(+), CD29(+), CD4(+)CD29(+), and CD4(+)CD25(+) cells in peripheral blood of colorectal carcinoma patients increased significantly, while the percentages of CD19(+) and human leukocyte antigen(locus) DR(HLA-DR) (+) cells decreased significantly(P<0.05) .The results of subgroup analysis showed that the patients' CD3(+)CD8(+) and CD4(+)CD25(+) cells increased significantly, CD19(+) and HLA-DR(+) cells decreased significantly after FOLFOX4 regimen chemotherapy(P<0.05) ;CD3(+)CD8(+) cells increased significantly and CD19(+) cells decreased significantly after XELOX regimen chemotherapy(P<0.05) ;while after FOLFRI regimen chemotherapy, there were no significant changes in all 21 lymphocyte subsets(P>0.05) . CD3(+), CD3(+)CD8(+), memory T lymphoctye(45RO(+)) , and CD4(+)CD45RO(+) cells increased significantly(P<0.05) in patients who received no more than 4 cycles of chemotherapy. However, in patients that received 5 to 8 cycles and more than 9 cycles chemotherapy, we only found significant decrease of HLADR(+) cells and significant increase of CD29(+) cells, respectively(P<0.05) .</p><p><b>CONCLUSIONS</b>The humoral immunity is attenuated after chemotherapy in colorectal carcinoma patients. FOLFOX4 may suppress the cellular immunity.Chemotherapy that is less than 4 cycles will strengthens the cellular immunity by modulating body immunity arrangement;however, along with the increase of chemotherapy cycles, the cellular immunity gradually declines in these patients.</p>

ABSTRACT

<p><b>BACKGROUND</b>Folate plays a critical role in nucleotide synthesis and DNA methylation, and was considered to be associated with anti-carcinogenesis.</p><p><b>RESULTS</b>from studies that concern the relationship between the folate intake or serum folate levels and lung cancer risk showed no consistency, which requires our further comprehensive meta-analysis.</p><p><b>METHODS</b>Systematic literature search was conducted to identify the relevant studies (published prior to February 2013) according to standard protocol. Estimated effects were calculated under both random-effects and fixed-effects models. Heterogeneity between studies and publication bias were also evaluated.</p><p><b>RESULTS</b>A total of 4390 cases and 6138 controls from 6 case-control studies revealed a significant overall inverse association between folate intake and lung cancer risk (OR = 0.74, 95%CI = 0.65 - 0.84, P < 0.001). Summary of 1438 cases and 2582 controls from 4 case-control studies and 44 cases out of a cohort of 1988 participants suggested a marginal association without significance (OR = 0.78, 95%CI = 0.60 - 1.02, P = 0.075) between high serum folate levels and less lung cancer susceptibility; however, subgroup analysis about population-based case-control studies showed that high serum folate levels significantly associated with the reduced lung cancer risk (OR = 0.76, 95%CI = 0.58 - 1.00, P = 0.048).</p><p><b>CONCLUSION</b>Higher folate intake can be a protective factor against lung cancer risk, and higher serum folate level is probably associated with reduced lung cancer risk in marginal manner, though more studies are warranted to confirm these associations.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To explore the expression of CD4(+), IL-17 and Foxp3 in non-small cell lung cancer (NSCLC) and their relationship with microvessel density (MVD).</p><p><b>METHODS</b>The expressions of CD4(+), IL-17, Foxp3, CD31 and CD34 in the cancer tissues of 102 NSCLC cases were detected by immunohistochemisty. The relationship among the expressions of CD4(+), IL-17, Foxp3 and MVD was analyzed. The count data were analyzed using χ(2) test. The measurement data were analyzed using single-factor analysis of variance, and significance level α = 0.05.</p><p><b>RESULTS</b>Among the factors affecting CD31 expression, there was a statistically significant difference between the strong positive Foxp3 expression (++) and negative (-) and positive expressions (+) in the NSCLC cancer tissues (P < 0.05), and between the expressions in stage I and III cancer tissues (P < 0.05). Among the factors affecting CD34 expression, there was a significant difference between positive IL-7 expression (+) and strong positive IL-7 expression (++) (P < 0.05), between negative Foxp3 expression (-) and strong positive Foxp3 expression (++) (P < 0.05), and between the CD34 expressions in stage I and III and between those in stage II and III NSCLC cancer tissues (P < 0.05).</p><p><b>CONCLUSIONS</b>CD4, IL-17and Foxp3 may be involved in the tumor suppression caused by host immune response, and are related with the NSCLC invasion and metastasis.</p>

ABSTRACT

An offline two-dimensional system combining a rat cardiac mascle cell membrane chromatography time-of-flight mass spectrometry (CMC-TOF/MS) with a high performance liquid chromatography time-of-flight mass spectrometry (HPLC-TOF/MS) was established for investigating the parent components and metabolites in rat urine samples after administration of the roots of Aconitum carmichaeli. On the basis of the analysis of the first dimension, retention components of the urine sample were collected into 30 fractions (one fraction per minute). Then offline analysis of the second dimension was carried out. 34 compounds including 24 parent alkaloids and 10 potential metabolites were identified from the dosed rat urine, and then binding affinities of different compounds on cell membranes were compared and influences of some functional groups on activity were estimated with the semi-quantification and curve fitting method. As a result, binding affinities decreased along with the process of deacylation, debenzoylation and demethylation, which may be related to the alleviation of toxicity in the procedure of herb processing or metabolism. Moreover, some minor components in rat urine (Songorine, 14-benzoylneoline, Deoxyaconitine, etc. ) exerted relatively strong affinity on cell membranes are worth exploring. The results delivered by the system suggest that the CMC can be applied to in vivo study.

ABSTRACT

<p><b>OBJECTIVE</b>To discuss the feasibility of estimating energy consumption of green laser in photoselective vaporization of prostate (PVP) based on the preoperative volume of prostate.</p><p><b>METHODS</b>From January 2005 to January 2007, 260 patients with benign prostatic hyperplasia (BPH) had been treated with PVP. Preoperative prostatic volume and post-two-weeks-operative prostatic volume of each patient were measured by transrectal ultrasound (TRUS). Energy consumption and emission time of green laser were recorded during the operation. Then we calculated the amount of energy consumption needed in vaporizing one gramme prostatic tissue, evaluated the correlation of energy consumption and preoperative volume of prostate by means of correlation-regression analysis, and established its regression equation.</p><p><b>RESULTS</b>The amount of energy consumption needed in vaporizing one gramme prostatic tissue was (6.9 ± 0.6)kJ. The correlation of energy consumption and preoperative volume of prostate was significantly positive linear correlated. Its regression equation was: Energy Consumption (kJ) = 4.7 x Preoperative Volume of Prostate (cm³) - 14.1.</p><p><b>CONCLUSION</b>It is feasible to estimate energy consumption of green laser in PVP based on preoperative volume of prostate.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the association between HPV infection and HLA-DQB1 alleles polymorphism in the cervical carcinogenesis in Uyghur women in southern Xinjiang.</p><p><b>METHODS</b>Twenty-one subtypes of HPV and the 5 alleles of HLA-DQB1 were detected from cervical tissues of 190 cervical cancer cases and 190 normal subjects by flow-through hybridization and gene chip (HybriMax) assay and polymerase chain reaction sequence-specific oligonucleotide technique (PCR-SSO).</p><p><b>RESULTS</b>(1) The positive rate of HPV in cervical cancer and control groups were 70.0% and 8.9%, respectively. HPV16 was the most common type in HPV positive cervical cancer patients with a rate of 64.7%, followed by HPV18 (2.6%), HPV68 (2.1%), HPV45 (1.6%), HPV58 (1.6%), HPV39 (1.6%), HPV31 (1.1%), HPV56 (1.1%), HPV59 (0.5%), HPV53 (0.5%) and HPV6 (0.5%), respectively. The positive rates of HPV and HPV16 in the cervical cancer group were significantly higher than that in the control group. (2) The frequency of HLA-DQB1*03 was significantly lower than that in the control group (OR = 0.683, 95%CI = 0.505 - 0.923). The frequency of other HLA alleles had no significant differences between the cervical cancer group and the control group. (3) In the cervical cancer group, the frequency of HLA-DQB1*06 in both HPV positive and HPV16 positive cases were significantly higher than that in both the HPV and HPV16 negative cases.</p><p><b>CONCLUSION</b>HPV16 is the most common type in both the cervical cancer and control groups. It appears that HLA-DQB1*03 may be a protective gene in the cervical carcinogenesis in southern Xinjiang Uyghur women, and the HLA-DQB1*06 is a susceptibility gene to HPV/HPV16 infection in Uyghur women. The study of HLA alleles in the cervical carcinogenesis in Uyghur women may play an important role in the intervention research of cervical cancer.</p>

ABSTRACT

Objective To compare the time-course of relaxant effect of rocuronium between patients of Uygur and Han nationalities.Methods Thirty ASA Ⅰ or Ⅱ patients (15 Uygur nationality,15 Han nationality) of both sexes,aged 20-55 yr weighing 45-73 kg were divided into 2 groups (n=15 each):group U Uygur nationality and group H Han nationality.Anesthesia was induced with midazolam,propofol,fentanyl and suxamethonium chloride.Tracheal intubation was performed and the patients were mechanically ventilated.Recuronium 0.6mg/kg was then given iv.Neuromuscular function was monitored with acceleromyograph using single stimulation of the ulna nerve.The onset time (time from injection of recuronium to maximal paralysis),nonresponse time (duration of maximal twitch depression),clinical duration (time required for the twitch to return to 25% of control height after injection of initial dose),75%recovery time (time for twitch to return to 75%of control height after injection of initial dose) and recovery index (time for twitch height to return from 25% to 75% of control height) were recorded.Results There was no significant difference in the onset time between the two nationalities.The time of nonresponse period,clinical duration and 75% recovery time were significantly shorter in Uygur patients than in Han patients.Recovery index was significantly shorter in Uygur patients.Conclusion There is a significant difference in the time-course of muscle relaxant effect of recuronium between Uygur and Han nationalities.The influence of nationality on recommended dosage of recuronimn should be considered.

ABSTRACT

<p><b>OBJECTIVES</b>To study the knowledge, attitude and practice (KAP) concerning asthma in parents of children with asthma and the related factors.</p><p><b>METHOD</b>Questionnaire survey was conducted by using the multi-center research methods in twenty hospitals with asthmatic clinic or pediatric clinic in Beijing from August to October in 2008. The investigation focused on Beijing permanent residents with children who have been diagnosed as asthma for more than 6 months.</p><p><b>RESULT</b>Totally 390 parents of asthmatic children were investigated among whom 351 provided valid questionnaires, the response rate reached 90.0%; 75.2% of the parents knew that the nature of asthma is a chronic allergic airway inflammatory disease; 54.4% of parents think that even if the child is in a state of asthma control he/she can participate in only mild exercise; 88.4% of parents consider that the long-term use of inhaled corticosteroid would have a mild effect on growth and development of children. Of the asthmatic children, 32.5% adhered to use inhaled corticosteroid prescription; 47.2% adhered to use leukotriene receptor modulator; 45.3% of parents of children with acute asthma attack will add antibiotics; 18.1% of parents would choose short-acting beta2-agonist. The multi-factors Logistic regression suggested that the parents' educational background and the frequency of referral in children with asthma under control may have an influences on the parents' KAP (P < 0.05, OR > 1).</p><p><b>CONCLUSION</b>The general understanding of asthma in asthmatic children's parents in Beijing area is good, the higher the parents' educational background and revisit frequency of asthmatic children whose disease is under control, the better the Parents' KAP.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To retrospectively analyze and evaluate the results of treatment for atlantoaxial instability or dislocation employing pedicle screws of atlas and axis.</p><p><b>METHODS</b>Thirty-one patients (23 male and 8 female) with atlantoaxial instability or dislocation were stabilized using pedicle screws of atlas and axis between May 2005 to January 2008. The patients ranged in age from 17 to 67 years (mean 43.5 years). Patients consisted of chronic odontoid fracture in 17, Os odontoideum in 8, fresh odontoid fracture in 4, transverse ligament rupture in 1, rheumatoid arthritis in 1. Clinical features included neck pain in 31; restricted neck movement in 28, varying degrees of spastic quadriparesis in 19. All patients underwent posterior C(1) to C(2) pedicle screw fixation. Operative time, intraoperative blood loss, complications were recorded, neurological and radiographic studies were carried.</p><p><b>RESULTS</b>Mean follow-up time was 13 months. Operative time averaged 2.5 h. Mean intraoperative blood loss was 300 ml. A patient had postoperative wound infection and was treated conservatively with antibiotics and local wound care. A patient developed pulmonary artery embolism and got well with anticoagulation. Satisfactory stability was achieved in all cases with no vascular and C(2) neuralgia. Average JOA score in 19 cases increased at final follow-up (P < 0.01). Solid fusion was achieved in 29 cases, fusion rate was 93.6%.</p><p><b>CONCLUSIONS</b>Stabilization of atlantoaxial complex via pedicle screws of atlas and axis has advantages of intraoperative restoration, easier placement of screw, solid fixation. It is a safe and effective treatment modality for posterior C(1-2) fusion.</p>
