Infection and inflammatory response can induce the brain damage in neonate,but the mechanism involved in it has not been elucidated completely.Proposed mechanisms include inflammatory response,cytokine and free radical-mediated injury,and excitatory amino acids-induced injury.The activation of microglia and selective vulnerability of immature oligodendrocyte play an important role in the whole process.Recent researches show that the fetal inflammatory response and complex gene regulation are also involved in the infection-induced brain damage.

Ascoviruses, iridoviruses, asfarviruses and poxviruses are all cytoplasmic DNA viruses. The evolutionary origins of cytoplasmic DNA viruses have never been fully addressed. Morphological, genetic and molecular data were used to test if all four cytoplasmic virus families (Ascoviridae, Iridoviridae, Asfarviridae, and Poxvirirdae) evolved from nuclear replicating baculoviruses and how the four virus groups are related. Molecular phylogenetic analyses using DNA polymerase predicted that cytoplasmic DNA viruses might have evolved from nuclear replicating baculoviruses, and that poxviruses and asfarviruses share a common ancestor with iridoviruses. These three cytoplasmic viruses again shared a common ancestor with ascoviruses. Morphological and genetic data predicted the same evolutionary trend as molecular data predicted. A genome sequence comparison showed that ascoviruses have more baculovirus protein homologues than do iridoviruses, which suggested that ascoviruses have evolved from baculoviruses and iridoviruses evolved from ascoviruses. Poxviruses showed genetic and morphological similarity to other cytoplamic viruses, such as ascoviruses, suggesting it has undergone reticulate evolution via hybridization, recombination and lateral gene transfer with other viruses. Within the ascovirus family, we tested if molecular phylogenetic analyses agree with biological inference; that is, ascovirus had an evolutionary trend of increasing genome size, expanding host range and widening tissue tropism for these viruses. Both molecular and biological data predicted this evolutionary trend. The phylogenetic relationship among the four species of ascovirus was predicted to be that TnAV-2 and HvAV-3 shared a common ancestor with SfAV-1 and the three virus species again shared a common ancestor with DpAV-4.

From original concept and literature of acupoint, the concept and clinical significance of ashi method is discussed, which clarifies that the essence of ashi method is to locate the acupoints by patients' sensitivity on force. The clinical application of heat-sensitive moxibustion has illustrated that positioning method of this therapy is based on the appearance of heat-sensitive moxibustion sensation. Although both types are based on patients' feeling, positioning method of heat-sensitive moxibustion stands on a new angle and uses a new method to locate acupoint. Therefore, it is believed that the positioning method of heat-sensitive moxibustion is the inheritance and development of ashi method.

OBJECTIVETo study the clinical features of neonatal diabetes mellitus (NDM).
METHODThirteen cases with NDM were seen in our department between Jul. 2004 and Sept. 2009. Their clinical features were reviewed retrospectively.
RESULTSThe average birth weight of the 13 cases was 2.30 kg. The median age at diagnosis was 2 months. The mean blood glucose at diagnosis was 22.2 mmol/L. Symptoms in 9 of 13 cases were exacerbated by infection and only 5 had typical symptoms of diabetes mellitus including polydipsia, polyuria, polyphagia and body weight loss. The common clinical findings included athrepsia, diuresis, and moderate dehydration. Ketoacidosis attacked 3 cases and 3 children had hypertriglyceridemia, meanwhile, 2 children had complications of blood clotting dysfunction and congenital cardiopathy, respectively. Autoantibody to insulin (IAA) was tested in 11 cases, all but one case was negative. Glycosylated hemoglobin was increased in 6 cases. Insulin treatment was started in all the 13 cases. The initial dose was 0.56-1.00 U/(kg × d), and the maximal dose was 1.35 U/(kg × d) depending on the variety of blood glucose. Blood glucose decreased significantly within 24 hours. Unfortunately, 1 case developed progressive blood glucose decline and recurrent hypoglycemia. Symptoms of the 3 cases who developed DKA were relieved 48 hours later, and their blood glucose was well under control. Among the 8 cases followed up, 4 had TNDM and 2 had PNDM. Unfortunately, 1 case died at the age of 3 months because insulin injection was stopped by the parents.
CONCLUSIONEarly diagnosis and prompt management may lead to favorable prognosis. Blood glucose monitoring is a valuable method to avoid misdiagnosis and NDM should be differentiated from stress hyperglycemia, iatrogenic, or other causes of hyperglycemia.

OBJECTIVETo study the oxidative stress induced by consumption of mercury-contaminated rice in rats, and to assess the possible public health risk of mercury contamination in Wanshan mining area.
METHODSSprague Dawley rats were fed the mercury-contaminated rice produced from Wanshan area for 90 days. The antioxidant status and the free radicals in rat serum were evaluated.
RESULTSHigh mercury accumulation in organs of rats fed the mercury-contaminated rice confirmed the server pollution of mercury in Wanshan mining area. The intensity of electron spin resonance (ESR) signal increased by 87.38% in rats fed the rice from Wanshan compared with that in the control rats fed the rice from Shanghai, suggesting that chronic dietary consumption of rice from mercury mining area could induce an aggravation of free radicals. Feeding the mercury-contaminated rice was associated with significant decreases in the antioxidant enzymatic activities of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) and concentration of serum nitric oxide (NO), but it had no effect on serum nitric oxide synthase (NOS) activity. Feeding the mercury-contaminated rice raised the level of serum malonyldialdehyde (MDA), indicating the occurrence of oxidative stress.
CONCLUSIONThe long-term dietary consumption of mercury-contaminated rice induces the aggravation of free radicals and exerts oxidative stress.

OBJECTIVETo study the diagnosis and treatment of persistent hyperinsulinemic hypoglycemia of infancy.
METHODSThe clinical data of 12 infants with persistent hyperinsulinemic hypoglycemia were retrospectively reviewed.
RESULTSConvulsion, cyanosis, lethargy, refusing milk sucking, irritability and sweating were common symptoms. The laboratory findings displayed persistent hypoglycemia and hyperinsulinism in all of the 12 infants. The glucagon test showed positive and no urine ketones were detected in all of the 12 infants. Seven infants were treated with oral diazoxide (5-15 mg/kg daily) and 4 infants showed effective to the therapy. One patient was given subtotal pancreatectomy and the blood glucose level was restored to normal after operation. Of the 12 infants, 6 presented psychomotor retardation in a follow-up of 2 months to 67 months, 3 had loss to follow-up and 3 were still in a follow-up.
CONCLUSIONSThe measurement of blood glucose, blood insulin and urinary ketons is helpful in the diagnosis of persistent hyperinsulinemic hypoglycemia of infancy. Diazoxide therapy is effective in some of patients.

Purpose To study the clinical features, immunophenotypes and prognostic factors of primary breast diffuse large B-celllymphoma (PBDLBCL). Methods The clinical pathological data of 49 cases of PBDLBCL during January 2006 to December 2016 were retrospectively analysed, and the basic clinical and pathologic data, pathologic types and the immunohistochemical slides by EnVision method for staining were summarized. Results 47 cases were women and 2 cases were men. The age ranged from 24 to 79 year old with the median age of 48 year old. On microscopic observation, tumor cells were large to medium-sized which characterized as diffuse infiltration between the lobules of mammary gland, around the duct, interstitial and fat tissue, some were single file cord pattern. The immunophenotype showed 37 cases were of non-GCB, 12 cases were GCB type. Ki-67 index were greater than 40%. According to Ann Arbor staging, 16 cases were stage I EA, 28 cases were stage Ⅱ EA, 5 cases were stage Ⅳ E. IPI score: 30 cases with 0 ~1 score, 10 cases with 2 score, 9 cases with 3 score. Patients were followed up from 5 to 146 months, The 3-year overall survival (OS) rate was 51.2% and 5-year OS rate was 36.7%, Single factor analysis showed that there were statistically significant difference in clinical stage, levels of LDH, IPI score, BCL-2 protein expression, and BCL-6 protein expression in 3 and 5 years of OS rate. The multiple factor analysis of Cox regression showed that the increase of IPI risk classification was the independent adverse prognostic factor of primary breast diffuse large B-cell lymphoma. Conclusion The diagnosis of PBDLBCL is confirmed by pathological biopsy and immunohistochemical markers. The immunophenotype was mainly non-GCB type. Comprehensive treatment including surgery, chemotherapy and radiotherapy is appropriate. The prognosis should be comprehensively evaluated by multiple factors. IPI increase risk classification is the independent adverse prognostic factor.
