Restoration of an injured lower dorsal ascending reticular activating system in a patient with intraventricular hemorrhage

正The ascending reticular activating system(ARAS)plays a key role in the control of arousal and awareness for consciousness(Paus,2000;Zeman,2001;Van der Werf et al.,2002;Weiss et al.,2007;Siposan and Aliu,2014).It is well known that the ARAS originates from the reticular formation(RF)of the brainstem,and connects to the cerebral cortex via intralaminar     

Treatment of acne vulgaris with fractional radiofrequency microneedling

Fractional radiofrequency microneedling is a novel radiofrequency technique that uses insulated microneedles to deliver energy to the deep dermis at the point of penetration without destruction of the epidermis. It has been used for the treatment of various dermatological conditions including wrinkles, atrophic scars and hypertrophic scars. There have been few studies evaluating the efficacy of fractional radiofrequency microneedling in the treatment of acne, and none measuring objective parameters like the number of inflammatory and non‐inflammatory acne lesions or sebum excretion levels. The safety and efficacy of fractional radiofrequency microneedling in the treatment of acne vulgaris was investigated. In a prospective clinical trial, 25 patients with moderate to severe acne were treated with fractional radiofrequency microneedling. The procedure was carried out three times at 1‐month intervals. Acne lesion count, subjective satisfaction score, sebum excretion level and adverse effects were assessed at baseline and at 4, 8 and 12 weeks after the first treatment as well as 4, 8 and 12 weeks after the last treatment. Number of acne lesions (inflammatory and non‐inflammatory) decreased. Sebum excretion and subjective satisfaction were more favorable at every time point compared with the baseline values (P < 0.05). Inflammatory lesions responded better than non‐inflammatory lesions (P < 0.05). Adverse effects such as pinpoint bleeding, pain and erythema were noted, but were transient and not severe enough to stop treatment. Fractional radiofrequency microneedling is a safe and effective treatment for acne vulgaris.     

Kaposi’s sarcoma-associated herpesvirus infection of human bone-marrow-derived mesenchymal stem cells and their angiogenic potential

Kaposi’s sarcoma (KS) is a vascular tumor, and KS spindle cells express endothelial-cell-specific markers. Generally, it is believed that KS originates from endothelial cells. However, as various mesodermal-derived tissue markers are also expressed in KS spindle cells, the exact origin of KS still needs to be elucidated. Here, Kaposi’s sarcoma-associated herpesvirus (KSHV) was used to infect human mesenchymal stem cells derived from bone marrow (hMSC-bm), and we investigated the angiogenic properties of these cells, which are one of the most important pathologic features of KS. KSHV-infected hMSC-bm showed latent infection and increased tube formation activity in vitro. In addition, the expression of endothelial-cell-specific markers and a growth factor that affects the angiogenesis of endothelial cells was induced in KSHV-infected cells. This study suggests that human mesenchymal stem cells might have important roles in KS pathogenesis.     

Tapia's Syndrome after Posterior Cervical Spine Surgery under General Anesthesia

We present a case report to remind surgeons of this unusual complication that can occur in any surgery, even posterior cervical spine surgery under general anesthesia and discuss its causes, treatment methods, and the follow-up results in the literature. The peripheral Tapia''s syndrome is a rare complication of anesthetic airway management. Main symptoms are hoarseness of voice and difficulty of tongue movement. Tapia''s syndrome after endotracheal general anesthesia is believed to be due to pressure neuropathy of the vagus nerve and the hypoglossal nerve caused by the endotracheal tube. To our knowledge, no report has been published or given an explanation for Tapia''s syndrome after posterior cervical spine surgery. Two patients who underwent posterior cervical surgery complained hoarseness and tongue palsy postoperatively. There is no direct anatomical relation between the operation, the vagus nerves and the hypoglossal nerves, and there is no record of displacement or malposition of the endotracheal tube. After several months, all symptoms are resolved. To avoid this problem in posterior cervical spine surgery, we suggest paying special attention to the position of the endotracheal tube to avoid excessive neck flexion before and during the positioning of the patient.     

Influences of the G2350A polymorphism in the ACE Gene on cardiac structure and function of ball game players

Background  

Except for the I/D polymorphism in the angiotensin I-converting enzyme (ACE) gene, there were few reports about the relationship between other genetic polymorphisms in this gene and the changes in cardiac structure and function of athletes. Thus, we investigated whether the G2350A polymorphism in the ACE gene is associated with the changes in cardiac structure and function of ball game players. Total 85 healthy ball game players were recruited in this study, and they were composed of 35 controls and 50 ball game players, respectively. Cardiac structure and function were measured by 2-D echocardiography, and the G2350A polymorphism in the ACE gene analyzed by the SNaPshot method.     

Clinical Efficacy of Cervical Length and Volume for Prediction of Labor Onset in VBAC Candidates

Background: The purpose of this research is to discover whether measurement of cervical length and cervical volume at term is helpful in predicting the onset of labor in VBAC candidates.Methods: Transvaginal sonographic evaluations of the cervixes of pregnant women who desired to undergo VBAC were performed between 36 - 40 weeks gestation. Clinical information such as labor onset time, gestational age at delivery and delivery mode was gathered from medical records.Results: A total of 514 pregnant women participated in this study. Cervical length was significantly longer in the group that delivered 7 days or more after measurement than in the group that delivered within 7 days of measurement (43±0.77 cm vs. 2.99±0.72 cm, p< 0.001). Cervical volume was significantly larger in the group that delivered at and after 7 days than in the group that delivered within 7 days (29.21±11.62 cm³ vs. 34.07±13.41 cm³, p=0.014). The cervical length ROC curve was significantly more predictive than the cervical volume ROC curve (AUC: 0.711 vs 0.594, p= 0.001). There were no significant differences between the combined cervical length/volume ROC curve and the cervical length ROC curve alone (p= 0.565). The AUC of the cervical length ROC curve to predict postterm pregnancy was 0.729.Conclusion: Measuring cervical length is helpful in predicting the onset of spontaneous labor within 7 days and posterm delivery in VBAC candidates.
