AIM: To observe the effects of Decoction of Bu-Shen-Huo-Xue-Xie-Zhuo (BSHXXZ) on focal segmental glomerulosclerosis (FSGS) in rats. METHODS: Unilateral nephrectomy was adopted firstly, one week later adrimycin was intravenously adminstered to 20 rats twice in a 23-day period to establish an advanced focal segmental glomerulosclerosis model in the rat. Changes in urine protein, blood chemistry, and histology of the kidney were investigated for 110 days after unilateral nephrectomy. RESULTS: The BSHXXZ decoction reduced edema, proteinuria, hyperlipidemia, azotemia and ascites, and increased albumin in blood. Light microscopic, electron microscopic, immunohistochemical and polarizing microscopic examination all showed that the pathologic changes in the treatment group were less than that of the model group. CONCLUSION: Decoction of BSHXXZ could markedly improve renal function and delay the progression of glomerulosclerosis and renal interstitial fibrosis.

BACKGROUND:For depressed skul fractures in children, retaining their skul and narrowing surgical incision meet the concept of minimaly invasive surgery as important as ensuring the surgical safety and therapeutic effects, which is also the requirement of children’s parents. OBJECTIVE:To explore the curative effects of in suit replantation of free bone fragments based on a smal incision in children with depressed skul fractures. METHODS: Fifteen patients with depressed skul fractures, aged 3-16 years, were selected and subject to CT examination and manual examination of the scalp at fractured site under general anesthesia for labeling fracture range. Then, one or two bone fragments corresponding to the fracture site and size were selected. A smal incision with a length equal to the outer edge of bone fragments removed. Postoperative folow-up was employed for observation of clinical effects. RESULTS AND CONCLUSION:An incision, 5-7 cm in length, were made, and one bone fragment was removed from six cases, and two bone fractures were removed from nine cases. Intraoperatively, there were six cases of epidural hematoma, three cases of subdural hematoma, six cases of brain contusion and bleeding. For fracture fixation, one skul lock was used in eight cases, two skul locks in six cases, and three bone plates in one cases. Postoperative CT showed 12 cases of good fracture reduction displayed basic symmetry with the contralateral skul; 3 cases showed partialy depressed bone fragments that were less than 0.5 cm; 6 cases had a little skul defects with a diameter < 1.0 cm; 6 cases had mild epidural hematoma or effusion which was eliminated after conservative treatment. Eleven of 15 cases were folowed for 2 month to 3 years, and showed no changes in skul shape on CT films compared with those at discharge and presented with good stability. In addition, there were one case of mild limb paralysis, one case of mild language barriers, and one case of mild seizures, but al these cased were wel controled by drugs. These findings indicate that in situ replantation of partialy free bone fragments is suitable for depressed skul fractures in children.

Currently, there is no unified rules of access qualification for emergency triage nurses in mainland China. Unifying the standard of the emergency triage nurse admission and providing the unified pre-job training and assessment can greatly enhance the quality of emergency pre - triage and reduce the occurrence of medical disputes. This article described the qualification requirements of emergency triage nurses at home and abroad and compared the differences in the responsibilities and the content and methods of training.

Objective To explore effect of early moxibustion intervention on cerebral Aβ1-40 in a mouse model of Alzheimer disease (AD) and the mechanism of action of moxibusion in preventing and treating AD.Method Gene phenotype in transgenic AD passage mice was identified using PCR. One and a half-month-old female Tg6799 transgenic mice were randomly allocated, including nine mice to a model group and eight mice to a treatment group. Nine C57BL/6J wild type female mice of the same age and background constituted a normal control group. Wheat-grain-sized moxa cone moxibustion on bilateral points Xinshu(BL15) and Shenshu(BL23) was given to the treatment group. After the completion of treatment, Aβ1-40 expression in mouse frontal cortex and hippocampal region was determined using the immunohistochemical method.Result Aβ1-40 expression in mouse frontal cortex and hippocampal region decreased significantly in the treatment group compared with the model group (P<0.01,P<0.05). Conclusion Early moxibustion intervention can decrease cerebral Aβ1-40 expression and delay AD pathological process in a mouse model of AD.

Objective To describe the clinical characteristics of idiopathic ventricular fibrillation (IVF) with fragmented QRS complex (f-QRS) and J wave in resting electrocardiogram. Methods We reviewed data from 21 case subjects in our hospital who were resuscitated after cardiac arrest due to IVF and assessed the prevalence of f-QRS and J wave in resting electrocardiogram (ECG). All the case subjects were classified among three groups based on the electrocardiographic morphology: group I, both f-QRS and J wave were observed (n = 6), group II, only J wave was observed (n = 9), group III, neither f-QRS nor J wave was observed (n = 6). Population characteristics, history of syncope or sudden cardiac arrest, incidence of ventricular fibrillation (VF), and circumstance of VF were evaluated among the three groups. Results The incidence of index events (syncope, survived cardiac arrest and VF episodes recorded in implantable cardioverter defibrillator (ICD) or pacemakers) was 13.4 ± 5.6 per-year in group I, 10.8 ± 3.9 per-year in group II, and 9.8 ± 4.2 per-year in group III. There were significant differences in incidences among the three groups, the most frequent index events were observed in group I. The hazard ratio for incidence was 3.2 (95%CI, 1.1-7.9; P = 0.01). The history and circumstance of the index events were different among the groups. In group I, all the index events occurred during sleep in early morning. In group II, four subjects suffered VF during strenuous physical activities or agitation state, two during sleep in early morning, three in usual activity. In group III, one subject suffered VF during sleep in early morning, one in agitation state, four in usual activity. Conclusions This study suggests that the IVF patients with the combined appearance of f-QRS and J wave in the resting ECG suffer an increased risk of VF, this subgroup of IVF patients has a unique clinical feature.

OBJECTIVETo investigate the clinical significance of 24-hour blood pressure monitoring (ABPM) for evaluating the treatment outcome of nerve-mediated syncope (NMS) in children.

METHODSTwenty-eight children with NMS confirmed by a head-up tilt table test (HUTT) (12 males and 16 females, aged 6-13 years) and with a chief complaint of unexplained syncope or pre-syncope between February 2010 and August 2012, were included in the study. These children received health education combined with therapy using oral rehydration salts solution and were then reexamined for clinical symptoms as well as HUTT and ABPM results.

RESULTSOf 28 NMS cases, 22 were vasodepressive type, 5 were mixed type, and 1 was cardioinhibitory type. The follow-up showed that 27 (96%) of all cases had improved clinical symptoms, and 18 (64%) had improved HUTT results. The ABPM follow-up revealed no significant changes in 24-hour mean systolic pressure, 24-hour mean diastolic pressure, daytime mean systolic pressure, daytime mean diastolic pressure, nighttime mean systolic pressure, nighttime mean diastolic pressure, day-night difference of systolic pressure, and day-night difference of diastolic pressure after treatment (P>0.05). The percentage of children with a dipper blood pressure pattern increased from 29% (8/28) before treatment to 50% (14/28) after treatment; the percentage of children with a non-dipper blood pressure pattern decreased from 71% (20/28) before treatment to 50% (14/28) after treatment.

CONCLUSIONSAs an effective, objective and non-invasive monitoring means, ABPM is of some clinical significance for evaluating the treatment outcome of NMS in children.

OBJECTIVE: To study the clinical effect of calsurf, a domestic exogenous pulmonary surfactant, in the treatment of severe neonatal infectious pneumonia. METHODS: A total of 208 neonates with severe infectious pneumonia who hospitalized in 5 hospitals of China were enrolled. According to their parents' wishes on admission, these neonates were administered with conventional treatment (control group; n=81) and calsurf  treatment + conventional treatment (calsurf treatment group, n=127). The two groups were compared in terms of the degree of oxygen dependence on admission, blood gas parameters before and after treatment, lung ultrasound results, duration of mechanical ventilation, length of hospital stay, hospital costs, complications and prognosis. RESULTS: Compared with the control group on admission, the calsurf treatment group had significantly higher inhaled oxygen concentration and partial pressure of carbon dioxide and significantly lower arterial partial pressure of oxygen and oxygenation index (P<0.01). After 1 hour of treatment, both groups had significant improvements in the above indices (P<0.05), and the improvements were more significant in the calsurf treatment group (P<0.05). After 4-6 hours of calsurf administration, there was a significant reduction in the degree of pulmonary consolidation. The calsurf treatment group had significantly shorter duration of mechanical ventilation and length of hospital stay than the control group, while there was no significant difference in the incidence rate of complications between the two groups. The neonates of both groups had a good prognosis. CONCLUSIONS In neonates with severe infectious pneumonia, calsurf treatment can significantly improve oxygenation, reduce the degree of pulmonary consolidation, and shorten the duration of mechanical ventilation and length of hospital stay. Therefore, it should be considered in neonates with severe infectious pneumonia.
