Direct posterior restoration and internal fixation technique for children with congenital atlantoaxial subluxation / 中华神经医学杂志

Objective To explore the clinical effect of direct posterior restoration and screw-rod (plate) internal fixation technique for the treatment of children with congenital atlantoaxial subluxation.Methods Seven children with congenital atlantoaxial subluxation,admitted to our hospital from April 2008 to March 2011, were chosen in our study; and 3 of them were combined with tonsil hernia of cerebellum and 3 with occipitalization. Japanese Orthopedic Association (JOA) scale was used to evaluate the patient's condition. Five patients were treated by internal fixation with occipital bone screw-axis (C2) pedicle screw and 2 were with atlas C1-C2.Articulatio atlantoepistrophica repositioning was performed during the operation. The post-operative improvement degree and therapeutic effect of these patients were assessed based on the JOA scores and imaging. Results All the patients were followed up for 1-15 months (average 3.2 months). The clinical symptoms of all patients improved significantly. The positions of all screws were fine 1 month after operation. Three-dimensional CT showed that occipital/interbody fusions were good in 3 patients.JOA scores after the surgery were 7-16 with an average scores of (12.03±3.58),which were significantly different as compared with those before the surgery ([7.56±3.16], P＜0.05). Conclusion Direct posterior restoration and internal fixation technique is a safe and effective method for the treatment of children with congenital atlantoaxial subluxation.

Clinical features of middle cranial fossa arachnoid cyst and its surgical intervention / 中华神经医学杂志

Objective o investigate the clinical characteristics of middle cranial fossa arachnoid cyst (MCFAC) and its therapeutic effects with different surgical methods. Methods Three hundred and fifty-two patients with MCFAC (about 2.58% of patients with intracranial space occupying lesion),admitted to our hospital from May 2001 to May 2008, were chosen in out study; their clinical data,surgical approach and prognosis were analyzed retrospectively. The gender ratio of patient with MCFAC adopted resection of arachnoid cyst and arachnoid cyst-peritoneal shunt was performed in 28 patients.Results Follow-up was performed for 3 months to 3 years. The headache completely disappeared in 75 patients (58.59%) and partial remission in 41 (32.03%) after the operation. The frequency and degree of seizures obviously decreased in 8 of the patients with MCFIAC. Eleven patients with dystropy,attention-deficit disorder or difficulty of learning got improvement. The head circumference and local skull eminentia was stable. The cyst disappeared completely in 46 patients (13.07%), partially in 257 (73.01%) and no changes in 49 (13.92%). Conclusion The clinical features of MCFAC is that it mainly occur in the left side of male. The younger the patient with MCFAC is, the better the treatment effect in the surgical intervention is. good outcome can be achieved by resection of the parietal layer of arachnoid cysts. The indication of shunt with meso-low pressure shunt system is for larger arachnoid cyst.

Clinical study on Zhuyu Tongfu serial recipe combined with acupuncture and massotherapy in treating hypertensive cerebral hemorrhage / 中国结合医学杂志

<p><b>OBJECTIVE</b>To observe the clinical efficacy and mechanism of Zhuyu Tongfu (ZYTF) Serial Recipe combined with acupuncture and massotherapy in treating hypertensive cerebral hemorrhage (HCH).</p><p><b>METHODS</b>One hundred and eighteen patients with hypertensive cerebral hemorrhage, on the basis of conventional Western medicine treatment, were randomly divided into ZYTF combined with acupuncture and massotherapy group (treated group) and simple Western medicine group (control group); the clinical efficacy, neurofunction deficit scoring (NDS) alterations and hematoma absorption rate of both groups were observed, and also the plasma superoxide dismutase (SOD) activity, plasma lipid peroxidase (LPO) content, erythrocyte glutathion peroxidase (GSH-Px) activity, hematocrit (Ht) and the whole blood viscosity (Va) change were also observed.</p><p><b>RESULTS</b>In the treated group, the clinical efficacy, NDS improvement and hematoma absorption rate were superior to that of the control group; comparison between the two groups after treatment showed that plasma SOD activity and GSH-Px activity got more elevated and plasma LPO content, Ht and Va more lowered in the the treated group than those in the control group.</p><p><b>CONCLUSION</b>ZYTF combined with acupuncture and massotherapy has better effect, its therapeutic mechanism was possibly correlated to the elevation of plasma SOD activity, GSH-Px activity and lowering of plasma LPO content, Ht and Va.</p>

Observation on therapeutic effect of acupuncture at lateral cervical Jiaji points on cervical spondylosis of vertebroarterial type / 中国针灸

<p><b>OBJECTIVE</b>To compare therapeutic effects of acupuncture at lateral cervical Jiaji and at traditional Jiaji points on cervical spondylosis of vertebroarterial type.</p><p><b>METHODS</b>Seventy-two cases of vertebroarterial type cervical spondylosis were randomly divided into a needling lateral cervical Jiaji group (n=40) and a traditional Jiaji group (n=32). After 2 courses, therapeutic effects were evaluated and ultrasound Doppler's detection of skull was conducted.</p><p><b>RESULTS</b>The therapeutic effect in the lateral cervical Jiaji group was better than that in the traditional Jiaji group (P < 0.05); And there was a significant or very significant difference between the two groups in the velocity of blood flow and the index of vascular pulsation (P < 0.05 or P < 0.01).</p><p><b>CONCLUSION</b>The results of acupuncture at lateral cervical Jiaji points is better than that of acupuncture at traditional Jiaji points for treatment of cervical spondylosis of vertebroarterial type.</p>

Quantitative analysis of circulating DNA in serum of cancer patients / 中华肿瘤杂志

<p><b>OBJECTIVE</b>To develop a method for ng quantitation of circulating DNA in serum and explore the value in the diagnosis of cancer.</p><p><b>METHODS</b>Serum DNA was extracted by commercial "genomic DNA extraction kit" and detected by fluorescent dye (SYBR green I) staining. Loss of heterozygosity (LOH) at BRCA1 (D17S579, D17S855) and p53 (TP53, D17S786) in serum DNA was analyzed by PCR-based method.</p><p><b>RESULTS</b>SYBR green I dot staining could detect DNA as low as 2 ng. Using this method, we detected serum samples from 483 patients with various types of cancer and 150 healthy individuals. The mean DNA concentration in the normal controls was 22.2 +/- 13.4 ng/ml, while that in cancer patients was 81.3 +/- 98.3 ng/ml (P < 0.001). In 33 ovarian cancer patients with increased DNA level, 27(81.8%) displayed LOH in at least one of the four loci analyzed.</p><p><b>CONCLUSION</b>Circulating DNA in serum may become additional tumor marker for the diagnosis of cancer.</p>
