OBJECTIVERasmussen syndrome (RS) is a chronic inflammatory disease of unknown origin, usually affecting one brain hemisphere. The present study aimed to analyze the electroclinical characteristics and treatment of RS.

METHODSThe medical records of 16 children with RS were retrospectively reviewed.

RESULTSOf the 16 children, 8 were males and 8 were females. The age of onset was from 1 year and 11 months to 11 years and 6 months. The first symptom was seizure in all patients. The main seizure type was partial motor seizures. In all the patients, seizures gradually became frequent and in the form of epilepsia partialis continua (EPC). Thirteen cases developed hemiparesis. Fixed hemiparesis occurred from 2 months to 3 years after the onset of seizures. The cognitive deterioration was present in 14. The EEG background activity was abnormal in all the cases, asymmetric slow wave disturbances were bilateral but with unilateral predominance in 11, unilateral delta or theta wave in 8. The presence of interictal epileptiform discharges were found in all cases, unilateral in 11 and bilateral in 5. Seizures were recorded in all patients, no electroclinical correlation was found in 5. Serial magnetic resonance imaging (MRI) showed progressive unihemispheric or focal cortical atrophy in all cases. Six cases transiently showed focal cortical swelling or T2/FLAIR hyperintense signal on early scans. Antiepileptic drugs were not effective in any of the patients. Three of 10 patients receiving immunoglobulin, and 4 of 8 receiving corticosteroids, had some reduction of seizure frequency for a short period. Six patients accepted functional hemispherectomy, in 4 of them seizure no longer occurred and cognitive function was improved. The results of multiple subpial transection in 2 cases and focal resection in one patient were disappointing.

CONCLUSIONThe clinical features of RS were refractory partial epilepsy, progressive hemiplegia and cognitive deterioration. The EEG background was asymmetric with slow wave activity, interictal epileptiform discharges were unilateral or bilateral, no electroclinical correlation occurred. Serial MRI showed progressive unihemispheric focal cortical atrophy. Antiepileptic drugs were not effective for RS. In some patients, immunoglobulin or corticosteroids could reduce seizure frequency in the short term. Functional hemispherectomy could lead to seizure control and prevent further development of neurological impairment and cognitive deterioration.

Objective To investigate the prevalence and influencing factors related to abuse and negligence against the elderly in the rural areas. Methods 975 elderly over 60 years from 41counties in Anhui province were included. All participants completed an anonymous questionnaire including items as: educational background, marital condition, income, child-discipline, rude action to parents, daily activities, physical functions, having chronic illness, abuse and negligence against the elderly, etc. Results In the last year, rates of common physical abuse, serious physical abuse,emotional abuse, financial exploitation, negligence, overall abuse and negligence against the elderly were 4.5%, 1.5%, 26.9%, 4.9%, 7.2%, 29.9% respectively. Among the 281 victims, 80.4% reported that they were suffered more than 3 times of abuse and neglect episodes, and 34.9% reported that they were suffered more than 2 forms of abuse and negligence. The primary sadism was carried out by the daughter-in-law or son-in-law (43.2%) of the elderly. Low activity on daily life and having chronic illness were the risk factors causing common physical abuse while better education was the protective factor to it, Low ability in managing daily activity of living was the risk factor causing serions physical abuse. Less active on daily life and having rude action to parents were the risk factors to emotional abuse, but being strict with their children was the protective factor to emotional abuse. Less active on daily life, often beating their children and having rude action to parents were the risk factors related to financial exploitation. Less active on daily life, having rude action to parents and having bad physical functions were the risk factors causing negligence. Less active on daily life and having rude manner to parents were the risk factors of overall elderly abuse and negligence, but being strict with their children was protective factor to the abuse and negligence against the elderly. Conclusion High prevalence on abuse and negligence against the elderly was seen in the rural areas of China. Different forms on elderly abuse and negligence were affected by different factors that called for more attention to be paid to those elderly with lower ability in managing their daily life.

BACKGROUNDThe severity of respiratory distress was associated with neonatal prognosis. This study aimed to explore the clinical characteristics, therapeutic interventions and short-term outcomes of late preterm or term infants who required respiratory support, and compare the usage of different illness severity assessment tools.

METHODSSeven neonatal intensive care units in tertiary hospitals were recruited. From November 2008 to October 2009, neonates born at ≥ 34 weeks' gestational age, admitted at < 72 hours of age, requiring continuous positive airway pressure (CPAP) or mechanical ventilation for respiratory support were enrolled. Clinical data including demographic variables, underlying disease, complications, therapeutic interventions and short-term outcomes were collected. All infants were divided into three groups by Acute care of at-risk newborns (ACoRN) Respiratory Score < 5, 5 - 8, and > 8.

RESULTSDuring the study period, 503 newborn late preterm or term infants required respiratory support. The mean gestational age was (36.8 ± 2.2) weeks, mean birth weight was (2734.5 ± 603.5) g. The majority of the neonates were male (69.4%), late preterm (63.3%), delivered by cesarean section (74.8%), admitted in the first day of life (89.3%) and outborn (born at other hospitals, 76.9%). Of the cesarean section, 51.1% were performed electively. Infants in the severe group were more mature, had the highest rate of elective cesarean section, Apgar score < 7 at 5 minutes and resuscitated with intubation, the in-hospital mortality increased significantly. In total, 58.1% of the patients were supported with mechanical ventilation and 17.3% received high frequency oscillation. Adjunctive therapies were commonly needed. Higher rate of infants in severe group needed mechanical ventilation or high frequency oscillation, volume expansion, bicarbonate infusion or vasopressors therapy (P < 0.05). The incidence of complications was also increased significantly in severe group (P < 0.05). The in-hospital mortality in the severe group was significantly higher than other two groups (P < 0.05). ACoRN Respiratory Score was correlated with Score for Neonatal Acute Physiology-Version II (SNAP-II) (P < 0.01). High gestational age, high SNAP-II score and oxygenation index (OI), and Apgar score at 5 minutes < 5 were independent risks for death.

CONCLUSIONSNeonatal respiratory distress is still a common cause of hospitalization in China. Illness severity assessment is important for the management. ACoRN Respiratory Score which correlated with SNAP-II score is easy to use and may be helpful in facilitating the caregivers in local hospital to identify the early signs and make the transfer decision promptly.

MSC transplantation has been explored as a new clinical approach to stem cell-based therapies for bone diseases in regenerative medicine due to their osteogenic capability. However, only a small population of implanted MSC could successfully reach the injured areas. Therefore, enhancing MSC migration could be a beneficial strategy to improve the therapeutic potential of cell transplantation. Catharmus tinctorius volatile oil (CTVO) was found to facilitate MSC migration. Further exploration of the underlying molecular mechanism participating in the pro-migratory ability may provide a novel strategy to improve MSC transplantation efficacy. This study indicated that CTVO promotes MSC migration through enhancing ROCK2 mRNA and protein expressions. MSC migration induced by CTVO was blunted by ROCK2 inhibitor, which also decreased myosin light chain (MLC) phosphorylation. Meanwhile, the siRNA for ROCK2 inhibited the effect of CTVO on MSC migration ability and attenuated MLC phosphorylation, suggesting that CTVO may promote BMSC migration via the ROCK2/MLC signaling. Taken together, this study indicates that C. tinctorius volatile oil could enhance MSC migration via ROCK2/MLC signaling in vitro. C. tinctorius volatile oil-targeted therapy could be a beneficial strategy to improve the therapeutic potential of cell transplantation for bone diseases in regenerative medicine.

OBJECTIVE: To construct a preoperative evaluation system for partial nephrectomy using CT three-dimensional visualization technology and to explore its practical value. METHODS: The clinical data of the patients who underwent partial nephrectomy for renal tumors in Department of Urology, Peking University First Hospital were collected retrospectively. At the same time, the homogenized standard data of patients who underwent partial nephrectomy for renal tumors were collected in 16 clinical centers in China. The CT three-dimensional visualization system was applied (IPS system, Yorktal) to evaluate tumor anatomy, blood supply, perirenal fat and other information. The parameters were summarized to build a three-dimensional nephrometry system, on the basis of which virtual surgery design and intraoperative navigation were completed. RESULTS: A three-dimensional visualization image was established based on the enhanced CT urography. The nephrometry system included the longest diameter and volume of the tumor, proportion volume of tumor invading the parenchyma, maximum depth of the tumor invading the parenchyma, contact surface area, flatness of the tumor surface, renal segment where the tumor was located, vascular variation, and perirenal fat. The average two-dimensional diameter of the tumor was (2.78±1.43) cm, the average three-dimensional maximum diameter was (3.09±1.35) cm, and the average postoperative pathological size was (3.01±1.38) cm. The maximum tumor diameter in the three-dimensional image was significantly related to the prolonged renal artery clamping time and intra-operative blood loss (r=0.502, P=0.020; r=0.403, P=0.046). The three-dimensional and pathological tumor volume were (25.7±48.4) cm³ and (33.0±36.4) cm³, respectively (P=0.229). The tumor volume was significantly related to the intraoperative blood loss (r=0.660, P < 0.001). The proportion volume of the tumor invading into renal parenchyma was significantly related to the prolongation of renal artery clamping and the occurrence of postoperative complications (r=0.410, P=0.041; r=0.587, P=0.005). The tumor contact surface area and the presence of vascular variation did not show correlation with the perioperative data and postoperative complications. While the preoperative evaluation was completed, the reconstructed three-dimensional image could be zoomed, rotated, combined display, color adjustment, transparency, and simulated cutting on the Touch Viewer system. The process generally consisted of showing or hiding the tissue, adjusting the transparency of the interested area, rotating and zooming the image to match the position of the surgical patient. Together, these functions met the requirements of preoperative virtual surgery plan and intraoperative auxiliary navigation. CONCLUSION Three-dimensional images can provide a more intuitive anatomical structure. The CT three-dimensional visua-lization system clearly displays tumor anatomical parameters, blood supply and perirenal fat. The three-dimensional nephrometry system for renal tumors can help predict the difficulty of partial nephrectomy and perioperative complications. Importing the reconstructed three-dimensional visualization image into the specified program or robot operating system can complete virtual surgery and intraoperative navigation, helping the surgeon to better grasp the surgical process. The indexes included in the nephrometry system and the score weights of each index need to be confirmed and perfected by multi-center study with large samples.
