The syndrome differentiation standardization of Chinese medicine and treatment technologies is the premise of Chinese medicine's entry into the world. But its individualized diagnosis and therapeutic features are contrary to the specification of standardization. The achievement and existent problems in syndrome differentiation standardization of Chinese medicine and treatment technologies were summarized in this paper. The thinking ways and recommendations to solve were proposed as well.

Chronic intermitted hypoxia including sleep breathing disorder leads to brain injury. This study explores the potential therapeutic effects of grape seed proanthocyanidin as a neuroprotective agent. A rat model of chronic intermittent hypoxia was employed, and the animals were given low or high doses of grape seed proanthocyanidin. The ultrastructure changes in the brain, the biochemical components, and the animal behavior were examined. The results showed that with hypoxia exposure, neuronal mitochondria exhibited injuries at ultrastructural level, with increased malondialdehyde (MDA) content and reduced superoxide dismutase (SOD) activity. Terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) staining revealed increased cell apoptosis in hippocampus. In Morris water maze the animals showed decreased learning abilities, when compared to normal control. The administration of grape seed proanthocyanidin treatment reversed all these observed changes, and improved the learning behavior. We concluded that grape seed proanthocyanidin could alleviate the brain injury caused by hypoxia from sleep breathing disorder.

Objective To explore the relationship between esophagus cancer patients and both environmental and genetic factors,through analyzing the data on birth orders from esophagus cancer patients of Shanxi province.Methods Both Greenwood and Haldane methods on birth order were used to study the 1101 cases with esophagus cancer from Shanxi province.All the patients had received surgery and were diagnosed,by pathological evidence.First certificates of the patients were confirmed through the standard genetic epidemiologic investigation.Birth order was investigated on probands of the 1101 cases with esophagus cancer and their 44 siblings.Results Results form the Greenwood method showed that there was a tendency for cases with esophagus cancer in birth orders First to Third.However,the Haldane method showed that the results were quite different between actual value and the average theory value of 6A (6A(actual value)=17 118,(X)6A(average theory value) =19 290,X=∣6A-(X)6A∣/√V6A =7.63,X ＞ 2) which suggested that the birth order had some effects on the occurrence of esophagus cancer.In addition,the actual value of 6A was lower than the theoretic average value,and the parents at younger productive age or baby at the first birth was easy to develop esophagus cancer.Conclusion Esophagus cancer was related with the birth order,especially at early order,which was not consistent with the national reports on esophagus cancer.Results from this study suggested that there were certain effects of environmental risk factors on esophagus cancer patients.

OBJECTIVETo prepare and characterize monoclonal antibodies (mAb) and polyclonal antibodies against nucleocapsid (N) protein of severe acute respiratory syndrome (SARS)-associated coronavirus (SARS-CoV) and to establish antibodies-based sandwich ELISA for detecting N protein of SARS-CoV, which might apply to early diagnosis of patients with SARS-CoV infection.

METHODSBALB/c mice were immunized with purified recombinant N protein of SARS-CoV for producing mAbs, and New Zealand white rabbits were immunized for producing polyclonal antibodies. The identification of antibodies was performed using indirect enzyme-linked immunosorbent assay (ELISA), indirect fluorescent-antibody assay (IFA), and Western immunoblotting. Capturing and detecting antibodies were selected by pairing the mAbs and polyclonal antibodies one by one and an antibodies-based sandwich antigen capture ELISA was used for detecting N antigen of SARS-CoV.

RESULTSNine mAbs and hyperimmune rabbit polyclonal antibodies, specifically against SARS-CoV nucleocapsid protein were obtained. Using paired ELISA assay, three mAbs N1E8, N8E1 and N10E4 were selected as capturing antibody and rabbit polyclonal antibodies as detecting antibody then triple antibodies-based sandwich ELISA was established following horseradish peroxidase (HRP)-conjugated goat anti-rabbit immunoglobulin G. The recombinant N protein was used as a standard to establish a detection sensitivity of approximated 50 pg/ml with this assay. When tested with 420 serum specimens from serologically confirmed SARS patients, the positive rates of serum N protein were 90.1%, 23% and 0%, in which sera collected from 1 to 10 days, 11 to 20 days and beyond 21 days respectively after the onset of symptoms. The specificity of the assay was 99.86% in 715 control serum specimens. There was no cross-reaction with other respiratory viruses and coronaviruses.

CONCLUSIONSpecific and high affinity mAbs and rabbit polyclonal antibodies were obtained. By paired and optimized sandwich ELISA, a sensitive and specific antigen capture ELISA was established for detecting N antigen of SARS-CoV, which might apply to early diagnosis, source tracing and epidemiological studies of SARS.

In order to evaluate the efficiency of ITS2 and psbA-trnH sequences used as DNA barcodes to distinguish Plantaginis Semen from its adulterants, we collected 71 samples of Plantaginis Semen and its adulterants. The ITS2 and psbA-trnH sequences were aligned through Clustal W, and the genetic distances were calculated by kimura 2-parameter (K2P) model and the Neighbor-Joining (NJ) phylogenetic trees were constructed using MEGA 5.1. The results indicated that the ITS2 sequence lengths of Plantago asiatica and P. depressa were 199 bp and 200 bp, respectively; the maximum intra-specific K2P distance were lower than the minimum inter-specific K2P distance; the NJ tree based on ITS2 sequence indicated that Plantaginis Semen and its adulterants could be distinguished clearly. The sequence lengths of psbA-trnH of both P. asiatica and P. depressa were 340 bp; the maximum intra-specific K2P distances were lower than the minimum inter-specific K2P distance; the NJ tree based on psbA-trnH sequence showed that Plantaginis Semen can be distinguished clearly from its adulterants except for P. major. Therefore, ITS2 sequences can be used as an ideal DNA barcode to distinguish Plantaginis Semen from its adulterants.

OBJECTIVETo investigate the risk factors for early disseminated intravascular coagulation (DIC) in neonates with sepsis.

METHODSA retrospective clinical study was performed on 100 neonates with a confirmed diagnosis of sepsis between 2012 and 2013. The children were classified into normal coagulation group, non-overt DIC group (early DIC group), and overt DIC group (late DIC group) based on the ISTH overt DIC scoring system. The clinical manifestations and risk factors were analyzed statistically.

RESULTSEarly DIC occurred in 44 (44%) cases in the 100 neonates with sepsis. The incidence of sclerema showed significant differences between the three groups (P<0.05). Asphyxia, bleeding, and Gram-negative bacterial infection were independent risk factors for early DIC.

CONCLUSIONSCoagulation function should be actively monitored and early intervention measures should be taken for neonates with asphyxia, bleeding, and Gram-negative bacterial infection to prevent early DIC from progressing to late DIC.
