OBJECTIVETo investigate the incidence of nosocomial infections of newborn infants in neonates and to explore the risk factors and strategies of infection control.
METHODSThere were 433 confirmed cases of nosocomial infection in the neonatal ward of the authors' hospital from January 2007 to December 2009. Their data of epidemiological and clinical characteristics, results of etiological examinations and antibiotic resistance were retrospectively analyzed.
RESULTSDuring the study, the number of hospitalizations were 6437. Nosocomial infection occurred in 433 patients 513 times. The overall nosocomial infection rate was 6.82%. The overall hospitalization days were 73 663 and nosocomial infection patient-day rates were 6.96‰. The VAP infection rate was 28.7‰. The CRBSI rate was 3.5‰. Gestational age (OR = 1.049), mechanical ventilation (OR = 1.810), umbilical vein catheter (OR = 1.106), hospitalization days (OR = 1.081), premature rupture of membrane (OR = 1.433) were the risk factors for the development of nosocomial infection. There were 197 (38.4%) cases of pneumonia, which was the most common nosocomial infection in Neonatal Ward. There were 129 cases of ventilator-associated pneumonia (VAP), which accounts for 65.5% of pneumonia and 24.4% of cases treated with ventilator. The next was sepsis, 124 cases (24.2%) and 64 cases of diarrheal disease (12.7%). One hundred and eighty two (54.4%) strains of isolates were Gram-negative bacteria, which accounted for the highest proportion. The predominant pathogens of Gram-negative bacteria were Klebsiella pneumoniae (19.6%), followed by Acinetobacter baumannii (8.1%), Pseudomonas aeruginosa (7.2%), Stenotrophomonas maltophilia (4.8%) and Escherichia coli (4.8%). The isolation rates of Klebsiella pneumoniae and Escherichia coli with positive extended-spectrum beta-lactamases (ESBLs) were 91.4% and 75%, respectively. Those two bacteria were universally resistant to cephalosporins. The rate of resistance to imipenem of Klebsiella pneumoniae, Acinetobacter baumannii and Pseudomonas aeruginosa were 1.5%, 11.1% and 41.7%. The isolation rates of methicillin-resistant Staphylococcus aureus and methicillin-resistant coagulase-negative Staphylococcus were 28.6% and 95.5%.
CONCLUSIONIt is important to identify the high risk factors for nosocomial infections in newborn infants. To shorten time for mechanical ventilation and hospitalization days, removal of the central venous catheter as early as possible would be conducive to reducing the morbidity of nosocomial infection. The main pathogens were Gram-negative bacteria. The multidrug resistance of Enterobacteriaceae and Non-fermenters is serious.

OBJECTIVETo observe the therapeutic effect of Xuesaitong soft capsule (XST) and its effect on platelet counts, coagulation factor 1 (CF1) as well as hemorrheologic indexes in treating patients with acute cerebral infarction (ACI).
METHODSTwo hundred and four patients with ACI were assigned into two groups, the control group (n = 96) and the treated group (n = 108). They were all treated with conventional Western medicines, including mannitol, troxerutin, citicoline, piracetam and aspirin, while to the treated group, XST was given additionally through oral intake, twice a day, 2 capsules each time for 8 successive weeks. The clinical efficacy was evaluated according to the nerve function deficits scoring and the changes of platelet count. CF1 and hemorrheological indexes were measured before and after treatment.
RESULTSThe total effective rate was 87.0% in the treated group, and 87.5% in the control group, respectively, showing insignificant difference between them. But the markedly effective rate in the treated group (66.7%) was significantly higher than that in the control group (27.1%, P < 0.01). The count of platelet was not changed significantly in both groups after treatment, while CF1 in them evidently lowered at the end of the 4th and 8th weeks of treatment, but showed insignificant difference between the two groups. The hematocrit, whole blood viscosity and plasma viscosity in both groups were all improved significantly after treatment, but also showed insignificant difference in comparison of the two groups.
CONCLUSIONXST has good efficacy in auxiliary treatment of patients with ACI, though its mechanism remains to be further explored.

OBJECTIVEIntra-ventricular hemorrhage (IVH) is one of the most serious complications of preterm infants. Significant numbers of the surviving infants with severe IVH go on to develop post-hemorrhagic hydrocephalus (PHH). The management of PHH remains a very challenging problem for both neonatologists and pediatric neurosurgeons. This study aimed to evaluate the efficacy and safety of the use of Ommaya reservoirs and serial cerebrospinal fluid (CSF) drainage in the management of a series of neonates with PHH.
METHODBetween January 1, 2003 and December 30, 2005, 15 consecutive newborn infants with IVH grades III to IV, complicated with progressive ventricular dilatation, underwent placement of an Ommaya reservoir. CSF was intermittently aspirated percutaneously from the reservoir. The amount and frequency of CSF aspiration were based on the clinical presentation and the follow-up results of serial cranial ultrasonograms or CT scans. The changes of CSF cell counts and chemistries were also followed. Patients whose progressive ventricular dilatation persisted despite serial CSF aspiration through Ommaya reservoir eventually had ventriculo-peritoneal shunts (V-P shunt) placed. All the patients were followed up in the outpatient clinic after discharge from the hospital and the neurodevelopmental outcomes were evaluated through 18-36 months of age.
RESULTA total of 15 infants were included in this series. Of them, 11 were preterm infants who were at gestational ages of 29 to 34 weeks and 4 infants were full-term. All of the 4 full term infants presented with progressive ventricular dilatation after suffering from the intra-cranial hemorrhage (3 infants were due to vitamin K deficiency and 1 was due to birth trauma). Thirteen infants had grade III IVH, and 2 had grade IV IVH based on initial cranial ultrasonographic and CT scans. The mean age when IVH was diagnosed was (9 +/- 1) days in preterm infants and (22 +/- 7) days in full-term infants; the mean age when Ommaya reservoir was placed was (18 +/- 11) days in preterm infants and (31 +/- 7) days in full-term infants. All the infants tolerated the surgical procedure well. The Ommaya reservoir was tapped for an average of (21.5 +/- 4.6) times per patient. The mean CSF volume per tap was (10.2 +/- 1.3) ml/kg. The values of CSF protein, glucose and cell counts slowly reached normal levels at approximately 3 - 5 weeks after the placement of the reservoir. The velocity of head circumference increase per week was less than 1 cm in 13 patients in 1 - 4 weeks after the placement of the reservoir and the size of ventricles decreased gradually. By 12 - 18 months, 12 infants had normal size ventricles, and 1 patient still had mild ventricular dilation at 36 months. Two infants developed progressive hydrocephalus after serial CSF aspiration through Ommaya reservoir. One infant had a V-P shunt placed at 2 months of age and another infant died at 3 months of age at home after parents refused further therapy. Complications consisted of reservoir leaking and CSF infection at 16th day of placement in one patient after repeated tapping. By the end of 18 - 36 months of follow-up, 11 of 14 infants were considered normal, two patients had mild impairment in neurodevelopmental outcome (both had spastic bilateral lower limbs paresis, and one of whom also had amblyopia) and the other had seizure disorder.
CONCLUSIONThe results from this series indicate that the placement of an Ommaya reservoir is relatively safe in newborn infants and is useful in the initial management of neonates with PHH and may be beneficial in improving their neurodevelopmental outcomes. A multicenter randomized trial may be needed to further validate the results of this report.

OBJECTIVETo assess the effect of a liquid embolic agent 2-poly-hydroxyethyl -methacrylate (2-P-HEMA) for renal artery embolization in rabbits.
METHODSThe precipitation time of different concentrations (2%, 3.5%, 5%, 6.5%, 8% and 9.5%) of 2-P-HEMA dissolved in different solutions (ethanol, ethanol/iobitridol, and ethanol/Bi2O3) were determined in flowing water. The mixtures of 2-P-HEMA (2%, 5%, and 8%) with ethanol/ Bi2O3 were injected into the renal arteries of the rabbits, and the artery-embolizing effects were assessed using angiography at 2 and 12 weeks after the injection, with also macroscopic and microscopic examination of the embolized kidneys.
RESULTSThe mixtures of 2-P-HEMA and ethanol formed flocculent precipitation a few seconds after injection into flowing water, and the precipitation time showed no significant variations with the concentration of 2-P-HEMA in the mixture. Low and moderate concentrations of 2-P-HEMA could pass through the microcatheter smoothly with little injection resistance, and resulted in complete occlusion of the renal arteries without adhesion to the microcatheter. Angiography at 2 and 12 weeks detected no recanalization of the occluded renal arteries. Macroscopically, the lumen of the renal arteries was found to be occluded by the embolic agents, and deep penetration of the embolic agents into the glomerular arteries was observed microscopically. The mixture containing high-concentration 2-P-HEMA was difficult to deliver through the microcatheter due to high injection resistance.
CONCLUSION2-P-HEMA can be rapidly precipitated after injection into flowing water, and allows complete embolization of the renal arteries of rabbits at proper concentrations, suggesting its great potential as an endovascular liquid embolic agent.

OBJECTIVETo analyse the relationships among HBV genotypes, HBV DNA levels and histopathological features of the livers of familial grouped hepatitis B patients in the Tianjin area.
METHODSOne hundred familial grouped hepatitis B (CHB) patients were enrolled in this study. Thirty-five of the 100 patients were chronic asymptomatic HBsAg carriers (ASC) and 65/100 were mild CHB patients. Their HBV genotypes and HBV-DNA levels were detected and liver biopsies were performed for analyzing the pathological features.
RESULTSSeven patients were of HBV genotype B (7%), and most of them had a HBV DNA level in the middle 10(3-5) copies/ml (57.14%). The histopathological features of the livers were of different degrees of injury. Eleven patients HBV was of genotype BC (11%); their HBV DNA levels were from 10(3-5) copies/ml (45.45%) to 10(6-7)copies/ml (36.36%). Their liver pathology showed slight or severe injuries (< or = G2 90.91%, < or = S(2) 81.82%). Eighty-two patients HBV was of genotype C (82%), and among the 82, 29 were ASC and 53 were CHB. Among the ASC, most of them had a high HBV DNA level (72.41%), and all of them had different degrees of liver injury. Among the CHB, their HBV DNA levels were 10(6-7) copies/ml (39.62%) and more than or equal 10(8) copies/ml (49.06%). The liver histopathological features were > or = G(2) in 38 patients (71.70%), and > or = S(2) in 25 patients (47.17%).
CONCLUSIONS(1) In the majority, HBV of the family gathered hepatitis B patients living in Tianjin is of genotype C and they have a high HBV-DNA level and severe liver pathological injuries. These features of the family gathered hepatitis B patients are the main factors causing the unfavorable prognosis of the patients. (2) There is inflammation of different degrees in the livers and high HBV DNA levels in all the family gathered ASC patients. Antiviral therapy should be planned according to the pathological features in patients livers. (3) Liver biopsies should be performed routinely before their antiviral therapy.

OBJECTIVETo study the risk factors for neonatal ventilator-associated pneumonia (VAP) and the changes of isolated pathogens in the last eight years.
METHODSThe clinical data of 230 neonates who were admitted into the neonatal intensive care unit (NICU) and received mechanical ventilation for equal to or longer than 48 hrs in 2008 were retrospectively reviewed. The isolated pathogens were compared with those of eight years ago.
RESULTSThe incidence of VAP (25.2%) in the year 2008 was lower than that of eight years ago (36.1%; P<0.05). The development of VAP was negatively correlated with the gestational age and the birth weight, but positively correlated with the duration of mechanical ventilation, intubation times, duration of hospitalization, presence of gastrointestinal bleeding and need for blood products transfusion. The main isolated pathogens were opportunistic antibiotics resistant bacteria, and the majority was gram negative bacilli (77%). The most frequently detected gram negative bacilli were Klebsiella (20%), Stenotrophomonas maltophilia (18%) and Acinetobacter (13%). Streptococcus mitis was the most frequently detected gram positive bacilli (14%). The distribution pattern of pathogens isolated in the same NICU eight years ago was somewhat different: Klebsiella (23%), Pseudomonas aeruginosa (17%), Acinetobacter (16%), Streptococcus mitis (11%), Fungi (1%) and Candida albicans (1%).
CONCLUSIONSThe incidence of VAP is correlated with gestational age, birth weight, duration of mechanical ventilation and hospitalization, intubation times, presence of gastrointestinal bleeding and need for blood products transfusion. The main isolated pathogens are usually antibiotic resistant opportunistic bacteria. The detection rate of Stenotrophomonas maltophilia increased and that of Pseudomonas aeruginosa decreased when compared with eight years ago.

OBJECTIVETo study the neoplasm with perivascular epithelioid cell differentiation (PEComa) with respect to their morphologic, immunohistochemical and clinical phenotypes.
METHODSThree PEComas were included in this study, one located at the left uterine horn, and two presented as a mass in the uterine corpus. The tumors were examined by histopathology and immunohistochemistry.
RESULTSThe lesions were composed of spindle, blunt epithelioid cells, with foci of, or scattered, cells showing adipose differentiation in two cases. The myomelanocytic differentiation was demonstrated, proving the diagnosis as PEComa. Mild nuclear atypia and focal necrosis was observed in one lesion, and the rest two showed malignant morphologic phenotypes including moderate nuclear atypia and coagulative necrosis. The mitotic and Ki67-labelling indices ranged from 0.5/10 HPF to 14/10 HPF and 0.6% to 7.0%, respectively. All of the three patients remain alive. Malignant nature of the two lesions with worrisome morphology was confirmed by occurrence of metastases after hysterectomy.
CONCLUSIONPEComa is a rare tumor, occurring preferentially in the uterus. It is regarded as a tumor with uncertain malignant potential, but a minority of them shows malignant clinical behaviors. Some pathologic parameters including large tumor size, sheet-like necrosis, marked nuclear atypia, elevated mitotic index (> or = 10/10 HPF), aberrant mitotic figure and vascular invasion may help to establish a diagnosis of malignant PEComa.

This study aimed to investigate the development status of traditional Chinese medicine(TCM) intervention in psoriasis in recent ten years, analyze the research hotspots, and summarize the development trends to provide reference materials for scholars in this field. Taking the available literature related to the field of TCM intervention in psoriasis as the research object, the trends, contents, and source publications were statistically analyzed based on bibliometrics. The research cooperation and co-occurrence of keywords in this field were studied by the knowledge map analysis method based on CiteSpace. The total number of Chinese papers was 2 993 and English papers 285. In terms of publication trend, the annual publication of English papers was low but showed an obvious upward trend, while the increase in Chinese papers fluctuated and tended to be flat. In terms of the content of Chinese papers published, TCM ranked first according to the discipline(2 415). In English papers, the number of publications in pharmacology and pharmaceutical science was the highest(87). Literature source analysis showed that the Chinese and English journals with the most publications were China Journal of Traditional Chinese Medicine and Pharmacy and Evidence Based Complementary and Alternative Medicine, respectively. Beijing University of Chinese Medicine published the most dissertations in China(99). The authors with the most publications in Chinese and English were LI Bin(Yueyang Hospital of Integrated Traditional Chinese and Western Medicine Affiliated to Shanghai University of Traditional Chinese Medicine) and LU Chuan-jian(Guangdong Hospital of Traditional Chinese Medicine). As revealed by the CiteSpace analysis of the research cooperation network, there were four mature and stable core teams in this field, but the cooperation intensity between different teams was weak. According to the keywords co-occurrence knowledge graph constructed by CiteSpace, the current hot keywords in this field are as follows: psoriasis, blood-heat syndrome, blood-stasis syndrome, fire needle, blood-dryness type, imiquimod, TCM bath, etiology and pathogenesis, cytokines, cupping therapy, etc. In summary, Chinese scholars have conducted active exploration and research in the field of TCM intervention in psoriasis in recent ten years. The overall development trend is good, and the breadth and depth of the research are constantly extending. It is suggested that relevant research should be free from discipline restrictions and strive for interdisciplinary integration.
