OBJECTIVEThis study aimed to investigate the effects of hirudin on the expression of transforming growth factor (TGF-β1) and basic fibroblast growth factor (bFGF) in human gingival fibroblasts (HGFs) in vitro, as well to explore its func- tion in the mechanism of gingival remodeling.
METHODSAfter culturing was performed with classic tissue-explant method, HGFs were derived from normal gingival and gingival hyperplasia tissues followed by orthodontic treatments with different concentrations of hirudin. The mRNA and protein expression levels of TGF-β1 and bFGF were respectively detected by real time quantity polymerase chain reaction and immunocytochemistry.
RESULTSCompared with normal HGFs, TGF-β1 expression promoted collagen synthesis of fibroblasts, whereas bFGF collagen synthesis was decreased in hyperplasia HGFs without hirudin (P < 0.05). Hirudin significantly upregulated the expression levels of bFGF but downregulated TGF-β1 in hyperplasia HGFs (P < 0.05).
CONCLUSIONOrthodontic force may influence the balance of collagen synthesis and degradation in HGFs. Hirudin may modulate the balance of HGF collagen metabolism, thereby promoting gingival remodeling.

Cough recognition provides important clinical information for the treatment of many respiratory diseases. A new Mel frequency cepstrum coefficient (MFCC) extracting method has been proposed on the basis of the distributional characteristics of cough spectrum. The whole frequency band was divided into several sub-bands, and the energy coefficient for each band was obtained by method of principle component analysis. Then non-uniform filter-bank in Mel frequency is designed to improve the extracting process of MFCC by distributing filters according to the spectrum energy coefficients. Cough recognition experiment using hidden Markov model was carried out, and the results

Objective: To investigate the childrens congenital and acquired nutritional status and the physical development among the different nationalities in Guizhou province; to find out the factors that greatly influence the childrens physical development. Methods: Investigations were carried out on the diet, height and the weight of the mothers during the early and late stage of their pregnancy and after the delivery of the babies. Results: The living conditions in the groups of Miao and Buyi were very poor. For the pregnant women among Han, Miao and Buyi groups, during their middle and late stage of the pregnancy, the intakes of protein, calcium and VB 2 did not reach 80% RDA. For the 2-4 years old children, the intake of protein was below 80% RDA. For those in Miao and Buyi groups, the chief source of protein was from cereals. There was a great insufficient intake of calcium and VB 2 in different age groups of the children mentioned above. With the increase of age, the infants of Buyi and Miao groups were gradually diverting from the standard criterion from 3rd or 4th month. The greatest difference was in Miao group, i.e. at the age of 6, the difference in height was 9.8 cm(male), 8.3 cm(female); the difference in weight was 1.64 kg(male), 1.92 kg(female). Conclusion: The physical development of the infants in Buyi and Miao groups is inferior to those in Han group. Besides the environmental influence, the quality and quantity of the protein in diet play an important role in physical development.

Objective To study the diagnosis and radical resection of hilar cholangiocarcinoma. Methods Retrospective analysis was made on the clinical feature and the effect of radical resection on 38 cases of hilar cholangiocarcinomas.Results Diagnosis was made in all of the patients preoperatively.The radical resection was perfomed on 38 patients.Of them, 3(7.9%) died after operation.After operation, 5 cases (13.2%) developed bile leakage,and 2 of the 5 cases developed subphrenic abscess,which were cured by drainage; 4(10.5%) had right hydrothorax that was cured by conservative therapy; and 3(7.9%)had incision split that was cured by resuture. Among the 35 postoperative survivors,34 (97.1%) were followed up, the 1- and 3-year survival rates were 91.9% and 35.2%.None of the patients survived for 5 years. Conclusions It′s still difficult to make early diagnosis in hilar cholangiocarcinoma.The diagnosis mainly depends on the combination of imaging examinations. Nowadays the radical resection rate of hilar cholangiocarunoma is still low, the recurrence and metastasis are common after operation, and few patients can survive for a long time. It suggests that even in radical operation for hilar cholangiocarcinoma, the regions of resection and sweep are not enough,and the operative procedure needs to improve further.
