ABSTRACT
In the perspective of the theory of “circular movement of yang qi ascending and descending”， the author explores the four-season pathogenesis and treatment of insomnia based on the seasonal changes of the body's yin-yang balance. It is believed that the core pathogenesis of insomnia lies in the spleen and stomach deficiency and the internal buildup of dampness. The four-season pathogenesis of insomnia focuses can be categorized into four aspects： abnormal ascending of yang qi in the spring， leading to the liver fire inflammation or the liver qi stagnation； Predominance of yang qi in the upper side of the heart and gallbladder fire in the summer； Lung disorder and abnormal descent of yang qi， resulting in yang-heat conversion into dryness or disharmony between nutrient qi and defensive qi； Abnormal hiding of yang qi， manifesting as floating yang or deficiency in both yin and yang in the winter. It is advocated to dynamically grasp the pathogenesis of insomnia in accordance with the changes in time. A treatment framework called “restoring ascending and descending of yang qi” is proposed， with the core focus on resolving dampness and strengthening the spleen， while also addressing the liver and strengthen the spleen， clearing and descending the heart and gallbladder， purifing and descending the lung qi， and suppressing hyperactive the yang and invigorating the kidneys in different seasons. This enrichment of the traditional Chinese medicine time medicine research in insomnia treatment， based on the characteristics of seasonal rhythmic time， aims to better serve clinical practice and provide ideas for the clinical diagnosis and treatment of insomnia.
ABSTRACT
Review of historical literature showed that the understanding of the indicated disease location of Modified FuMai Decoction （复脉汤加减方） has evolved from the upper jiao （焦） to the middle and lower jiao. Initially， it is used for the treatment of yin deficiency of both yin and yang in the upper jiao， changes to supplement stomach and produce fluids in the middle jiao， and is used to protect yin， clear the pathogens， conslidate yin and subdue yang so as to store the true yin of lower jiao. The unchanging principle of Fumai Decoction modifications is nourishing yin， while the changing aspects are determining the secondary treatment methods based on disease location of sanjiao， concomitant disease natures， internal injury or external contraction， warm disease or cold damage， thereby choosing the corresponding added or subtracted herbs， and providing reference for the application of classical formulas.
ABSTRACT
Plague, infectious disease in modern medicine, refers to a type of disease with strong pathogenicity and infectiousness, it refers to the infectious diseases of western medicine.

ABSTRACT
In order to meet the requirements of ultrasound bone density measurement, we designed a sofware based on Visual Studio C+ + 2008. The software includes interface design, acquisition and control, data processing and parameter extraction, data storage and printing. Excellent human-computer interface (HCI) will give users a convenient experience. Auto gain control (AGC) and digital filter can improve the precision effectively. In addition, we can observe waveform clearly in real time. By using USB communication, we can send control commands to the acquisition and get data effectively, which can shorten the measuring time. Then we calculated the speed of sound (SOS) and broadband ultrasound attenuation (BUA). Patients' information can be accessed by using XML document. Finally, the software offers printing function.

In order to meet the requirements of ultrasound bone density measurement, we proposed a software solution to improve the accuracy and speed of measurement of bone mineral density of the ultrasound bone densitometer. We used a high-speed USB interface chip FT232H, along with a high-speed AD converter chip to calculate speed of sound (SOS), broadband ultrasound attenuation (BUA ) and other bone density parameters in the PC software. This solution improved the accuracy of the measurement data, reduced the measurement time and increased the quality of the displayed image. It is well concluded that the new software can greatly improve the accuracy and transmission speed of bone density measurement data through a high-speed USB interface and a software data processing technology.

ABSTRACT
Objective To identify a locus for hereditary symmetrical dyschromatosis(HSD).Methods A genome-wide scan was performed with402microsatellite markers in two large Chinese HSD families to map the chromosome location of the susceptible gene.The LINKAGE software(Version5.10)and CYRILLIC soft-ware(Version2.01)were used for linkage and haplotype analysis.Results A locus was identified at chro-mosome1q11-1q21with a cumulative maximum two-point LOD score of8.85at microsatellite marker D1S2343(?=0.00).Haplotype analysis indicated that the candidate gene was located within11.6cM region between markers D1S2696and D1S2635.This was the first locus identified for HSD.This study provided a map location for isolation of the candidate genes causing HSD.Conclusion Chromosome1q11-1q21contains the candidate gene susceptible for dyschromatosis symmetrica hereditaria.
ABSTRACT
Objective To analyses the mutation of connexin30gene in a pedigree with hidrotic ec-todermal dysplasia(HED).Methods Blood samples were obtained from18affected and16normal individ-uals in this family.Mutation scanning was carried out by PCR and direct sequencing.Results A transition,at position on connexin30gene31(G→A),leading to a missense mutation(G11R),was detected in18patients,but was not found in16normal individuals in this HED family and in188unrelated,population-matched control individuals,which indicated that it did not represent common polymorphism.Conclusion A missense mutation(31G→A)in the connexin30gene has been determined in the pedigree with HED,which is probably one of the molecular bases of the pathogenesis of the disease.

ABSTRACT
Objective To map the locus of the gene CYLD1 for multiple familial trichoepithelioma (MFT), and identify the mutation of this gene in a large Chinese Han family with MFT. Methods The local genome scan was performed using 18 microsatellite markers spanning 9p21 and 16q12-q13 in this MFT family. Linkage software was used for two-point linkage analysis. All 17 coding exons of the CYLD1 gene and the adjacent splice sites were amplified using PCR. Mutation scanning was carried out by DNA sequencing. Results ① Two-point linkage analysis revealed a LOD score of 3.31 under the assumption of an autosomal dominant inheritance with disease-allele frequency of 0.00001 and penetrance of 99.9%. ② A four-basepair deletion of exon 18 in the CYLD1 gene was detected, designated c.2355-2358delCAGA. Conclusions Multiple familial trichoepithelioma is a genetically heterogeneous disorder. The gene CYLD1 for this MFT family localizes to 16q12-q13, not 9p21.

ABSTRACT
The origin and the course of the thoracic duct and its opening into the vein were studied in 150 cadavers including 15 fetuses and 138 infants. They are classfied into 5 types.1. The normol type of the thoracic duct begins in the abdominal cavity as a single trunk, It ascends along the right side of the aorta and empties into the venous system on the left side at the root of the neck. This type of the duct which is described in the general text book, occurred in 84.67 per cent.2. The two-trunk type of the thoracic duct begins in the abdominal cavity as two trunks and ascends along the each side of the aorta. The two trunks join together at different levels in the thorax forming a single trunk which empties into the venous system on the left side at the root of the neck. This type of the duct occurred in 10.66 per cent.3. The bifurcated-type of the thoracic duct starts in the abdominal cavity as a single trunk and passing cephalad on the right side of the aorta and divides into two branches at the level of the 6th～4th thoracic vertebra, The right branch opens into the venous svstem on the right side and the left branch opens into the venous system on the left side. This type of the duct occurred in 3.33 per cent. The type which ascends along the left side of the aorta was found.4. The right thoracic duct begins in the abdominal cavity as a single trunk and runs its entire course along the left side of the aorta. The termination opens into the right jugular venous angle. This type of the duct occurred in 0.67 per cent.5. The left thoracic duct begins in the abdominal cavity as a single trunk and ascends along the left side of the aorta. It empties into the left jugular venous angle. This type of the duct occurred in 0.67 per cent.
