OBJECTIVETo compare the clinical efficacy differences between acupoint catgut embedding and Kuntai capsule for perimenopausal syndrome, so as to provide an effective treatment method for perimenopausal syndrome.
METHODSThirty-three cases in the embedding group were treated with acupoint catgut embedding at back-shu points and front-mu points of liver, spleen and kidney combined with syndrome differentiation and disease differentiation, ten days per times; the Kuntai group was treated with oral administration of Kuntai capsule, 4 capsules each time, three times per day. The Kupperman index (KI) was observed in the two groups before treatment after 10 days, 30 days and 60 days of treatment, respectively; the efficacy was evaluated according to the ratio of KI.
RESULTSAfter the treatment, as treatment proceeded, the score of KI and ratio of KI were gradually reduced in two groups; the score of KI and ratio of KI in the embedding group after 10 days of treatment was lower than those in the Kuntai group (both P<0.05); after 10 days of treatment, the total effective rate was 36.4% (12/33) in the embedding group, which was superior to 3.0% (1/33) in the Kuntai group (P<0.05); however, after 30 days and 60 days of treatment, the differences of each index between two groups were not statistically significant (all P>0.05).
CONCLUSIONBoth the acupoint catgut embedding and Kuntai capsule could reduce the score of KI and improve clinical symptoms, and the acupoint catgut embedding has certain advantage on the early stage of treatment.

Objective To diagnose 6 LQTS families by genetic analysis. Methods A total aof 6 LQTS pedigrees with 43 family members were brought together for genetic diagnosis by using short-sequence tandem-repeat (SIR) markers or sequencing. Genomic DNA was extracted from blood samples by standard procedure. STR markers or KCNQ1, KCNH2 and SCN5A were amplified. The haplotype analysis for LQTS was performed. If the family got the negative haplotype analysis, the sequencing was performed. Results LQTS patients were always linkaged with the SCNSA gene in family 1. KCNH2 was linkaged with the disease in family 2 to 5.21 gene carriers were identified from these 5 families. A mutation (A561V-KCNH2) was only found in the proband of family 6 and an SNP (G1691A) was found in all the members of the family. Conclusion Genetic diagnosis can not only improve presymptomatic diagnosis,bnt also provide the basis for personal therapy and research on disease-causing mutations.

OBJECTIVETo prepare a new dosage formulation of activated carbon nanoparticles adsorbing mitomycin C (MMC-ACNP) and evaluate the beneficial effects of intraperitoneally applied MMC-ACNP as a drug delivery system for lymphatic targeting in preventing metastasis and recurrence of gastric cancer.
METHODSMMC-ACNP was prepared. Acute toxicity after its intraperitoneal administration was evaluated. An experiment on nude mice model with transplanted human gastric cancer in 6 groups was completed to assess the effects of drugs on intra-abdominal carcinomatosis.
RESULTSThe LD50 of MMC-ACNP was 46.80 mg/kg (in terms of MMC) while that of MMC aqueous solution was 9.33 mg/kg. The toxicity of MMC-ACNP was much less than that of the solution form. MMC-ACNP was superior to MMC aqueous solution in controlling carcinomatosis and tumor growth by intraperitoneal administration. Despite the high dose of MMC, leukopenia and thrombocytopenia were not observed in the MMC-ACNP treated group. Fine activated carbon particles adsorbing MMC entered the nuclei of tumor cells, so that the effects of the anticancer drug were reinforced.
CONCLUSIONMMC-ACNP gives a good promise of clinical use due to its advantages such as high selectivity and low toxicity.

BACKGROUNDNumerous studies have shown that reducing the level of tumor necrosis factor-alpha (TNFα) through the use of anti-TNF antibodies or soluble TNF receptor is a safe and efficacious treatment to inflammatory diseases such as rheumatoid arthritis. Therefore, novel approaches to achieve this outcome are desired. The aim of this study was to investigate the characterization of a small molecule inhibitor, Y316, which blocks TNF mRNA upregulation and TNF production by lipopolysaccharides (LPS) stimulated monocytes.
METHODSPeripheral blood mononuclear cells (PBMC) from healthy volunteers were plated in 24-well plates and stimulated with LPS (1 µg/ml), phorbol-12-myristate-13-acetate (PMA) (100 ng/ml), zymosan (10 µg/ml) and Tsst (100 ng/ml). Supernatants were collected after 4-hour culture at 37°C, and quantitative determination of TNFα, interleukin-1β (IL-1β), IL-6, IL-8, IL-10 and IL-2 production in the supernatants was performed by colorimetric enzyme-linked immunosorbent assay (ELISA). Total RNA of PBMC was isolated and cytokine mRNA quantitation was performed by using a RNA level measuring kit (R & D Systems). PBMC were pretreated with Y316 (10 µmol/L, 1 µmol/L, 0.1 µmol/L, 0.01 µol/L and 0.001 µmol/L) or dimethyl sulfoxide at 37°C for 10 minutes, and then stimulated with LPS or PMA, protein concentrations of p44.42, IKBα, P38 and Jun NH2-terminal kinase were determined by Western blotting. Cyclic adenosine-3',5'-monophosphate (cAMP) of PBMC was measured by enzyme immunoassay kit (Amersham Pharmacia Biotech).
RESULTSY316 blocked TNF production and inhibited the upregulation of TNF mRNA levels in response to LPS, and also prevented the production of IL-1 and IL-6. In contrast, Y316 augmented the production of IL-10 in LPS-stimulated monocytes. Y316 failed to prevent the production of IL-2 and TNF in antigen-stimulated T cells, suggesting that its effects may be cell-type specific. Y316 prevented the phosphorylation and activation of the MAPK, ERK, and therefore appeared to mediate its effects on TNF by acting at an early point in the signaling cascade induced in response to LPS. There was no effect of Y316 on cAMP levels either alone or in the presence of LPS.
CONCLUSIONSY316 appears to be a small molecule inhibiting TNF production, which may act via a novel mechanism. Identification of the target of Y316 may lead to the development of alternative strategies for achieving selective cytokine inhibition.

Objective To explore the establishment of a rat model of acute radiation-induced liver injury and sig-nificance of the dynamic changes of TGF-β1 expression.Methods Forty healthy 6-week old male SD rats were randomly divided into model group (n=30) and control group (n=10).The right liver of rats in the model group was given a single dose of 25 Gy 6 MV X-ray irradiation.Histopathological examination using HE staining and transmission electron microsco-py were conducted to observe the liver pathological changes in rats at 3, 5, and 10 days after irradiation, serum TGF-β1 was detected, and relevant indicators of liver function ( ALT, AST, ALP) were determined.Statistical analysis was per-formed using SPSS 17.0 software.Results At 3, 5 and 10 days after irradiation, early pathological changes in the liver cells were observed by electron microscopy, the expression of TGF-β1 was gradually increased with the time prolongation, and significant differences were found between the model group and the control group at different time points (P<0.05). The light microscopic observation of liver tissues did not show significant differences between the control group and model group.The liver ALT, AST, ALP at different time points did not show significant differences between the two groups ( P>0.05).Conclusion Electron microscopy can be used to evaluate the early changes of radiation-induced liver injury, pri-or to the alterations visible by routine light microscopy.TGF-β1 can be used to predict the degree of radiation-induced liver injury, and may be used as a sensitive serum cytokine in predicting the degree of radiation-induced acute liver injury.

OBJECTIVETo analyze the correlation between the phenotype and genotype of tooth agenesis using the tooth agenesis code (TAC) and the traditional descriptor for missing teeth.
METHODSPatients with isolated hypodontia caused by PAX9 or MSX1 mutation reported before May 2007 were enrolled. The teeth missing rate and TAC code were recorded. The missing teeth patterns caused by the two mutations were compared.
RESULTSThe teeth missing rates in each teeth positions were significantly different between maxillary and mandibular except maxillary central incisor, lateral incisor and mandibular canine, first molar (P<0.05, P<0.001). MSX1 gene mutation often led to the loss of maxillary first premolar, maxillary second premolar, and mandibular second premolar, while PAX9 gene mutation often led to the loss of the first, second, and third molars. The results were similar when analyzed either by TAC code analysis or by traditional descriptor.
CONCLUSIONSPAX9 and MSX1 gene mutation can cause different phenotypes of tooth agenesis. The TAC code can be used in the analysis of the correlation between phenotype and genotype of the missing teeth patients.

OBJECTIVETo observe the outcome of patients with perimembranous ventricular septal defects (VSD) after transcatheter closure.
METHODSFollow up data were analyzed in 445 VSD patients [203 males, (14.2 +/- 6.8) years] underwent transcatheter closure (TCVSD) using Amplatzer occluder or homemade occluder in Fu Wai hospital from November 2002 to November 2007. Left ventriculography and ascending aorta angiography were performed before and after TCVSD. Routine follow-up including electrocardiogram, echocardiography and X-ray were made at 1, 3, 6 and 12 months post TCVSD and followed at 12 months interval thereafter.
RESULTSMean follow up time was 25.6 months. There was no death during follow up. Procedure was successful in 417 patients (93.7%) and complete closure within 5 years was achieved in 410 patients (98.3%). During follow up, 2 patients developed complete left bundle branch block and left ventricle enlargement. Complete atrioventricular block was evidenced in 3 patients and 2 patients requiring permanent pacemaker implantations. Newly occurred moderate-large aortic valve regurgitation was found in 2 patients. Newly developed moderate-large tricuspid valve regurgitation was found in 2 patients and moderate mitral valve regurgitation was found in 1 patient.
CONCLUSIONTranscatheter closure of perimembranous ventricular septal defects is effective though this procedure is also associated with limited complications.

By comparing the drug distribution of breviscapine administered intranasally, orally and intrgvenous injected in rats' brain. After 0.4 mg x kg(-1) breviscapine was given by tail vein, intranasal and gastric perfusion administration to SD rats, cerebrospinal fluid was obtained by erebellomedllery cisternal puncture at different times. 125I labeling was used to determine the drug content of cerebrospinal fluid, cerebrum, cerebellum, medulla oblongata, olfactory region, olfactory bulb and blood in rats. AUCs were calculated by trapezoidal rule. The results showed that AUCs(0-240 min) (microg x min x g(-1)) of brain tissues were 11.686 +/- 1.919, 5.676 +/- 1.025, 7.989 +/- 0.925, 7.956 +/- 1.159, 17.465 +/- 2.136, 24.2 +/- 2.906 and 78.51 +/- 12.05, respectively, in the intranasal administration group; while those in the tail vein administration groups were 6.79 +/- 0.661, 6.251 +/- 0.40, 10.805 +/- 1.161, 9.146 +/- 1.04, 9.892 +/- 1.532, 7.871 +/- 0.842 and 173.91 +/- 10.02; and oral administration group were 0.868 +/- 0.167, 1.708 +/- 0.266, 2.867 +/- 0.725, 2.067 +/- 0.313, 1.361 +/- 0.308, 1.206 +/- 0.255 and 45.2 +/- 7.52, respectively. AUCs(0-240 min) of the brain tissues after oral, tail vein and intranasal administration were 22.29%, 29.18%, 95.49% of that of blood, respectively, it means that the absorption rate and drug distribution in the brain tissues after intranasal administration were higher than those of oral and tail vein administration. It is worth to investigate further the pharmacodynamic relationship.
