Traditional Chinese medicine (TCM) treatment for insomnia focused on the balance of Yin and Yang of internal organs. As to the treatment, Chinese medicine has a variety of treatment methods, such as herbal medicine, acupuncture, moxibustion, Guasha and so on. Besides, TCM also emphasized the importance to the comprehensive adjustment of life style and mental condition. This article summarized the clinical treatment forinsomnia from manyaspects, such as treatment according to the TCM patterns differentiationof internal organs, herbal medicine, acupuncture, life-style adjustment and other common therapies.

[Objective] The article summarized and discussed professor Li Qiyi's experience in treating coronary heart disease. [Methods] Discuss the experience of professor Li Qiyi in treating coronary heart disease from cause of disease, pthogenesis, combination of syndrome diferentiation and disease and so on. [Results] The pathogenesis of coronary heart disease is“deficiency of both qi and Yin, blockage of phlegm and blood stasis”. Professor Li Qiyi advocated we should combinate both syndrome diferentiation and disease according to the cause of disease and pthogenesis. Professor Li Qiyi often uses“Guanxinping”as basic decoction treatment in clinic and it can have excellent cure effect. [Conclusion] Professor Li Qiyi takes both Tongbi tonic and application of comprehensive therapy to tonify“qi and Yin”and eliminate phlegm and blood stasis which can have good cure effect . This method can relieve the clinical symptoms of the patients of coronary heart disease and delay the progress of the disease and then the patients can live a better life.

Hypermetabolism syndrome,especially in skeletal muscles,is exceedingly common in septic patients.Many studies suggest that the activity of ubiquitin-proteasome pathway is a vital procedure for hypermetabolism of skeletal muscles of septic patients and its activation can be influenced by a variety of factors,such as proinflammatory cytokine and glucocorticoid,etc.Evidences indicate that insulin has played an important role in opsonizing the activation of ubiquitin-proteasome pathway.This paper reviews the regulation effect of insulin to the hypermetabolism of the skeletal muscles of septic patients through ubiquitin-proteasome pathway.

Objective To investigate the efficacy of methotrexate combined with mifepristone prophylaxis for persistent ectopic pregnancy (PEP) after laparoscopic conservative surgery. Methods One hundred and twenty cases of tubal pregnancy were randomly divided into two groups by admission number, the study group (60 cases) were treated by mifepristone before laparoscopic conservative surgery and methotrexate combined with mifepristone after laparoscopic conservative surgery, but the control group (60 cases) were treated by laparoscopic conservative surgery, the bleeding was observated in the surgery,concentration of β-human chorionic gonadotrop ( β-hCG) was detected before operation and 1,3,7,12 d after operation. Results There were significant differences in β-hCG after operation 3,7,12 d between two groups(P<0.05). The bleeding was (21.8 ?.2) ml in study group,and (38.1 ?3.1) ml in control group, there was significant difference between two groups (P<0.05). In study group, the incidence of PEP was 0, and 3.33%(2/60) in control group. Conclusion Preoperative mifepristone and postoperative mifepristone combined with methotrexate in preventing PEP after laparoscopic conservative surgery is efficacy, and it can be chosen in clinic.

Objective To evaluate the clinical manifestation and operative treatment for the scolio-sis of Marfan syndrome, and analyze its clinical outcomes as well. Methods The retrospective study cov-ered 10 patients including 8 females and 2 males with an average age of 12.9 years (9 to 16 years), who had undergone operations from January 1990 to December 2002. The Cobb's angle in the coronal and sagittal plane, the trunk shift, the apex rotation and shift were evaluated both before and after operation respectively. In the group, there were four cases with family history. Of the 10 cases, the classification of scoliosis was single curve in two cases, double curves in six cases and three curves in two cases. Results All the pa-tients were followed up for a mean time of 15 months, ranged from 4 months to 3 years. The trunk shift changed from the mean distance of 2.17 cm to 1.41 cm. The apex rotation decreased about 1?. The apex shift changed from the mean distance of 4.57 cm to 2.14 cm. The mean Cobb's angle in the coronal plane changed from 88? to 42?. The correction rate was about 46.38% (18.18% to 81.54%). The Cobb's angle on the final follow-up was 46?( 11? to 96?), and the mean lost angle was 4?. The mean Cobb's angle of the thoracic kyphosis was 20?(-10? to 52?) preoperatively and 23?(0? to 35?)postoperatively, and 24?( 0? to 35?) on the final follow-up. The Cobb's angles of the thoracolumbar kyphosis of 5 cases improved from 85? to 10? after operations, and there was no angle loss on the follow-up. Conclusion The three dimensional corrective instrumentation can be used effectively for the correction of the scoliosis of Marfan syndrome. The critical points for the successful operation are the simultaneous correction of the coronal and sagittal plane deformities, prevention of the dural expansion in the lumbar or lumbosacral canal, rigid and multi-segmental internal fixation, extensive and ample bone fusion, and correct external fixation after operation.

Objective To analyze the value of three-dimensional computed tomography (CT) reconstruction imaging for the diagnosis and treatment of congenital scoliosis. Methods 76 patients with congenital scoliosis were examined with X-ray of total spine and three-dimensional CT reconstruction, and the results were analyzed. Compared with X-ray film, the findings with the CT imaging were classified into three groups: Group Ⅰ, no supplementary useful information was obtained; Group Ⅱ, further confirmation of findings which were unclear or ambiguous on X-ray film, with improved visualization and comprehension of the type of the deformity; Group Ⅲ, substantial new information was obtained. Results Group Ⅰ: 11 (14.5%) patients, without supplementary useful information obtained with three-dimensional CT reconstruction imaging. The patients aged from 2 to 16 years(11.00?10.09 years), and the Cobb angle ranged from 28? to 102?(55.60??21.06?). Group Ⅱ: 49 (64.5%) patients, with confirmatory finding or improved visualization and comprehension of the previously identified deformities obtained with CT imaging. The 49 patients aged from 4 to 28 years (13.53?4.47 years), and the Cobb angle ranged from 20? to 115? (55.41??23.44?). Group Ⅲ: 16 (21%) patients, with substantial new information obtained with CT reconstruction images which was unrecognized with X-ray film. The patients aged from 6 to 16 years (12.88?2.68 years),and the Cobb angle ranged from 37? to 145?(73.19??28.18?). The difference of age of patients between 3 groups was of no significance (P=0.052), but the difference of Cobb angle between 3 groups was significant statistically (P=0.039). Conclusion Three-dimensional and multiplanar reformatted CT imaging allows better visualization and understanding of the deformities of scoliosis, and supplementary useful information may be obtained which was obscure or unrecognized with X-ray film, especially for patients with severe deformities. Its application in clinical practice may contribute to the diagnosis of the type of deformity and the segments involved, as well as the individualized operative planning.

Objective After the implantation,coronary stent is expected at least to keep its integrity and maintain the predicated function for over 10 years or 4e8 cycles under the pulsatile loading conditions,so the fatigue property of the stent should be evaluated.Method The finite method was used to analyze the stress distribution of different phases and evaluate the fatigue life according to Goodman criteria,meanwhile,the accelerated fatigue experiment was also performed.Results It can be concluded that the dangerous points are all but located in the lateral inner surface of stent curvature.Conclusions The results prove that the fatigue property can be simulated through the finite element analysis,which can provide the theoretical guidance for the stent design.

The aim of this research is to investigate the preparation method of valve membrane in transcatheter bio- prosthetic valve, and to study the effect of chemical modification and cutting technology to tensile property and suture force property of valve membrane. We carried out a series of processes to perform the tests, such as firstly to test the crosslinking degree of valve membrane using ninhydrin method, then to test the tensile property and suture force property by using Instron's biomechanicAl testing equipment, and then to observe the collagen fiber orientation in valve membrane using Instron's biomechanical testing equipment and using field emission scanning electron microscopy. The study indicated that after the chemical modification, the crosslinking degree, tensile strength and suture force strength increasing rate of valve membrane were 93.78% ± 3. 2%, (8.24 ± 0.79) MPa, 102%, respectively. The valve membrane had a better biomechanical property and would be expected to become valve membrane in transcatheter bioprosthesis valve.

BACKGROUND:Primary dislocation after total hip arthroplasty is a major complication, besides prosthesis loosening. It is controversial whether joint capsule and external rotators should be repaired during total hip arthroplasty through posterolateral approach.
OBJECTIVE:To explore the clinical significance of joint capsule and external rotator repair on preventing hip dislocation after primary total hip arthroplasty through posterolateral approach.
METHODClinical data of patients with primary or secondary hip osteoarthritis after primary total hip arthroplasty through posterolateral approach were retrospectively analyzed. They were assigned to two groups according to different strategies of soft tissue repair. Control group did not receive posterior soft tissue repair. Combined repair group received the repair of joint capsule and short external rotators. Al patients were fol owed up for more than 1 year. Early dislocation was defined as the dislocation occurred within 1 year after operation. The effects of different repair methods on early dislocation rate were compared.
RESULTS AND CONCLUSION:There were 362 patients. Total y 390 case-times of primary total hip arthroplasty were included. Early dislocation occurred in 7 cases, of which 6 case-times in the control group (2.2%, 6/268), and 1 case-time in the repair group (0.8%, 1/122). There were significant differences in the incidence rate of early dislocation between the repair group and control group (P=0.012). These findings confirmed that the combined repair of posterior joint capsule and short external rotators could decrease the rate of early dislocation after primary total hip arthroplasty through posterolateral approach.

Boron neutron capture therapy (BNCT) is a new method for the precise treatment of cancers.By this method, cancer cells can be selectively killed by α particles and recoiling 7Li nuclei generated by the nuclear fission reaction occurring when the 10B isotope atoms in cancer cells capture thermal neutrons.The key to a successful BNCT is to deliver sufficient 10B into the cancer cells.The purpose of this review is to introduce the principles of BNCT and review recent progress in the development of neutron sources and boron delivery agents, as well as the result of BNCT clinical trials.
