Objective:This study was aimed to investigate the value of osteoclast differentiation factor (ODF) and osteoclastogen-esis inhibitory factor (OCIF) detection for clinical diagnosis and assessment of patient condition in bone metastasis of lung cancer. Methods:Data from 186 lung cancer patients who were preliminary diagnosed between July 2009 and April 2012 were analyzed. Cas-es were divided into the bone metastasis group with 82 cases (group A) and the non-bone metastasis group with 104 cases (group B). Concentrations of serum ODF and OCIF in each group were detected by ELISA. Results: ODF and OCIF values of group A were (32.22±6.22) ng/L and (41.23±8.13) ng/L, respectively, which were significantly higher than the corresponding values in group B [(8.35 ±5.42) ng/L and (10.15±4.42) ng/L]. The differences between the two groups were statistically significant (P<0.01). Areas under the re-ceiver operating characteristic curves of ODF and OCIF, which are used to diagnose bone metastasis in lung cancer, were 0.91 and 0.87, respectively, manifesting good diagnostic value. The sensitivity and specificity of ODF in diagnosing lung cancer with bone metastasis were 90.38%and 86.59%, respectively, and those of OCIF were 86.54%and 84.15%, respectively. ODF increased, whereas OCIF de-creased significantly, with increasing bone metastasis. ODF and OCIF concentrations in group A and the group with newly-found bone metastasis were significantly higher than those in group B, with statistically significant differences among these groups (P<0.01). Com-pared with group A, less difference was found in the ODF and OCIF of newly-found bone metastases, without statistical significance be-tween these groups (P>0.05). Conclusion:The serum ODF and OCIF concentrations significantly increase when bone metastasis oc-curs in lung cancer patients. Hence, these variables are useful as indices for monitoring bone metastases and evaluating patient condi-tion. An extensive application prospect is proposed.

Objective To analyze the electrophysiological characteristics of Hirayama disease and explore their significance for its diagnosis.MethodsElectrophysiological tests were performed on 18 patients who fulfilled the clinical criteria for Hirayama disease. Sixteen were males and 2 were females. The mean age was 24.9years old ( 19-58 years), and the mean case history was 5.2 years ( 1-40 years). The Hirayama disease was clearly unilateral in 10 patients and bilateral in 3, with 5 cases suspected of being bilateral. Motor neuron conduction velocity (MCV) and sensory neuron conduction velocity (SCV) were measured in the median and ulnar nerves.Electromyograms (EMGs) of the abductor digiti minimi, abductor pollicis brevis, extensor digitorum communis,brachioradialis muscle, biceps brachii and sternocleidomastoid were recorded in all cases. The MCV and SCV of the common peroneal nerve and an EMG of the tibialis anterior muscle were examined in one leg. The MCV and SCV of the ulnar nerve and EMGs of the abductor digiti minimi, extensor digitorum communis and brachioradialis muscles were inspected on the contralateral sides of 8 cases, including the patients suspected of suffering bilateral Hirayama disease. The MCVs of the median and ulnar nerves were examined segmentally by stimulating the nerves distally as well as proximally, and recording the amplitude, duration and area of compound muscle action potentials (CMAP) and changes in wave form, then determining whether there was a nerve conduction block.Results (1) No conduction block was detected in any median nerve or ulnar nerve among the 18 cases. (2) All the SCVs and sensory nerve action potentials of the median and ulnar nerves were normal. ( 3 ) All the MCVs and SCVs of the common peroneal nerve and the EMGs of the anterior tibialis muscles were normal. (4) MCV slowing in the upper limbs accounted for 41.3% (19/44) of the examined nerves. The rates of MCV decrease were 72.2% (13/18)in the ulnar nerve on the affected sides, 33.3% (6/18) in the median nerve on the affected sides and 0% (0/8)in the ulnar nerve on the contralateral sides. (5) Amplitude reduction in the CMAP in the upper limbs accounted for 81.8% (36/44) of the examined nerves. The rates of amplitude decrease were 100% (18/18) in the ulnar nerves of the affected sides, 77.8%(14/18) of median nerves on the affected side and 50%(4/8) of ulnar nerves on the contralateral side. ( 6 ) Upper limb EMGs revealed a rate of neurogenic damage of 47.0% ( 62/132). The EMGs decreased in 100% (18/18) of the abductor digiti minimi and abductor pollicis brevis on the affected side, 88.9% (16/18) of extensor digitorum communis on the affected side, 62.5% (5/8) of the abductor digiti minimi on the contralateral side, 37.5% (3/8) of the extensor digitorum communis on the contralateral side,5.6% ( 1/18 ) of the brachioradialis and biceps brachii muscles on the affected sides. There was no neurogenic damage of the contralateral brachioradialis muscle or the sternocleidomastoid on the affected side.Conclusions The electrophysiological features of Hirayama disease include unilateral or bilateral neurogenic damage in the upper limbs. According to the abnormal EMGs, spinal anterior horn cells on the affected sides were injured at C7-T1. C6and above C6 were rarely involved. The electrophysiological characteristics of Hirayama disease could provide a clear basis for localization and differentiation in Hirayama disease diagnosis.

Objective: To describe the differences of plasma folate concentration and prevalence of folate deficiency in genders and ages in Chinese adults aged 35 to 64 years. Methods: By cross-sectional analysis, plasma folate concentration was measured in 2 545 adults including men and women by microbiological assay. Results: (1) Men tended to have lower plasma folate concentration and higher prevalence of folate deficiency(9.70 nmol/L, 31.0%) than did women(14.2 nmol/L, 12.5%, P=0.001). (2) Men in South have significantly higher plasma folate concentration and lower prevalence of folate deficiency than in North. The difference of plasma folate concentration was not evident between urban and rural area, but evident in North between in winter and spring. There were no significant differences of prevalence of folate deficiency for men between urban and rural areas in both regions. For women, the differences of plasma folate concentration in areas were significant, which were higher in South and urban, and lower in North and rural areas. (3) Plasma folate concentration increased with age in Southern men. A similar trend for others was not significant. Conclusion: Men have lower plasma folate concentration and higher prevalence of plasma folate deficiency than do women. The distribution of plasma folate concentrations in urban and rural areas seems different between men and women.

Objective To investigate the effect of cold atmospheric plasma (CAP) on the healing of skin ulcers using Balb/c mice. Methods Wounds with a diameter 6 mm were created on each side of the backs of BalB/c mice ( n = 150) using a punch bioptome. The mice were assigned randomly into a control group ( wounds healed naturally), a laser group (wounds treated with a He-Ne laser for 10 min daily) and a CAP group (wounds treated with CAP for 10 min daily). Wound healing was evaluated on postoperative days (PODs) 4, 7, 10 and 14 in terms of percent wound closure. Ten mice per group were sacrificed on each of the evaluation days. Both wounds were removed and a histological examination was conducted. A scoring system was used to evaluate the wounds. The expression of vascular endothelial growth factors (VEGFs) in the wounded tissue was detected by using immunohistochemical methods on POD 7. The results were quantified using an HPIAS-1000 system. Results Compared with the control group, the average percentage of wound healing was significantly greater in the CAP group on PODs 7 and 10. The average scores on the histological examination were significantly higher in the CAP group on PODs 7, 10 and 14. Compared with the other two groups, the expression of VEGF was up-regulated significantly in the CAP group.Conclusions CAP can positively affect the wound healing process. This might be related to the up-regulation of VEGF in the wounded tissues.

Objective To explore the clinical therapeutic efficacy and value of endovascular embolization treatment for Hunt-Hess poor-grade intracranial aneurysms. Methods Eighty-seven patients with Hunt-Hess grade Ⅳ - Ⅴ intracranial aneurysrns were treated with endovascular embolization from May 2001 to February 2010,77 patients were grade Ⅳ and 10 patients were grade Ⅴ. Outcomes were assessed by using the Glasgow outcome scale (GOS). Results Follow-up time was from 3 months to 9 years. The therapeutic efficacy was as following according to GOS: 25 patients were grade Ⅰ , 5 patients were grade Ⅱ , 9 patients were grade Ⅲ , 12 patients were grade Ⅳ ,and 36 patients were grade Ⅴ. There were 55.17%(48/87) favorable outcome rate and 28.74% (25/87) mortality rate in all patients. There were 61.70%(29/47) favorable outcome rate and 25.53%(12/47) mortality rate in early stage treatment patients (diseased within 3 d), otherwise there were 47.50% (19/40) favorable outcome rate and 32.50%(13/40) mortality rate in medium and late stage treatment patients (diseased 3 d or later). There were no statistically significance in favorable outcome rate and mortality rate between them (P > 0.05). All the patients were embolized successfully ,technical complications occurred in 8 patients, 10 patients were found angiographic evidence of vasospasm. Conclusions Endovascular embolization is an effective method for treating Hunt-Hess poorgrade intracranial aneurysms. Early stage treatment is a feasible option because it can improve prognosis by reducing rebleeding and vasospasm.
