Precise location of liver segments has great significance in diagnosis and treatment of hepatic disease. In recent years, medical imaging and three-dimensional imaging techniques provide more diagnostic information about the location of liver segments and research methods for finding more precise liver segment classification. The progresses of hepatic segment imaging were reviewed in this article.

Objective]To discuss and analyze Professor Cheng Jing's clinical experience for treating decline in ovarian reserve(DOR). [Method]Through learning from the tutor in the outpatient service and case studies ,we analyzed and summarized Pro. Cheng's recognition on the etiology and pathogenesis of DOR,together with his dialectical way of thinking, combined therapy of Chinese and western medicine ,and empirical prescriptions. [Result] Pro. Cheng believes that this disease lies in the kidneys as wel as in the thoroughfare and conception meridian ,the pathogenesis is kidney deficiency and the imbalance of the thoroughfare and conception meridian,or combined with the stagnation of liver qi,spleen deficiency,and blood stasis and phlegm fire (heat); the therapy is mainly nourishing and warming kidneys as wel as conditioning the thoroughfare and conception meridian ,combined with Chinese medicine's periodical therapy,such as adjusting the circulation of qi and blood in livers,spleens,hearts and other organs. [Conclusions] Pro. Cheng's combined therapy of Chinese and western medicine for curing DOR ,of which his empirical prescriptions the Bushenyichongkangshuaitang is the main part,is of remarkable curative effect and significant clinical value.

OBJECTIVE: To introduce the methodology validation and quality control in bioanalytical procedures and its expected trend of development.METHODS: According to the bioanalytical validation reflected in FDA guidelines and other publications,based on the guidance of SFDA and the standard operating procedure of our phase I clinical trial lab,we summarized the procedure and questions of bioanalytical methodology validation.RESULTS: The methodology validation and quality control in bioanalytical procedures and the possible risks involved in the methodology validation were summarized.CONCLUSIONS: The established methodology validation in bioanalytical procedure and quality control contents were basically consummate,but the standards for the methodology validation should be formulated based on reality.

Objective To investigate the expression of VCAM-1 and E-selectin in vessel walls of the patients with thromboangiitis obliterans(TAO).Methods The vessel tissues were taken from 18 cases of amputation operation due to TAO and 16 cases of amputation operation due to non-vascular diseases.The expression of VCAM-1 and E-selectin were assessed by the immunohistochemical method.Results The positive expression rate of VCAM-1 in vessel wall of the patients with TAO was 77.8%(14/18),which of E-selectin was 72.2%(13/18);both of them were obviously higher than 6.3%(1/16) and 6.3%(1/16) in the control group.The positive rate of VCAM-1 and E-selectin had no correlation with the age,smoking amount,smoking time and drug use (P>0.05).Conclusion The expression of VCAM-1 and E-selectin have close correlation with the occurrence and development of TAO.Detecting the expression of VCAM-1 and E-selectin can serve as a diagnostic indicator of TAO.

Aspirin is widely used for the prophylaxis of ischemic events in patients with atherothrombotic complications or in populations with high risk of thrombotic events.However,despite the treatment of aspirin some patients experience thrombotic events,such as stroke.So the concept of "aspirin resistance" has been put forward.The mechanism of aspirin resistance is discussed in this article.

Objective To explore the technique and effect of selected three-field lymphadenectomy by left thoracotomy in treatment of thoracic middle or lower section esophageal squamous carcinoma. Methods From Jun. 2005 to Mar. 2009, 213 patients with thoracic middle or lower section of esophageal carcinoma received esophagectomy, bilateral mediastinal lymphadenectomy and pleural membrane resection.Group 1 -5, 7 - 12a, 16al, and 19 were performed to dissect abdominal lymph node and extended thoracic and abdominal lymphadenectomy and only lymph node extraction of mesoesophagus in neck field. Results 14197 lymphatic nodes(LN) were detected in 213 case. The average number of resected LN was 66. 65 ±24. 73. The metastatic lymph node was detected in 105 cases. The metastatic rate was 49.05% (105/213).There were 423 metastatic lymph nodes. The lymph nodes metastasis was 2. 97% (423/14197) of all dissected lymphatic nodes. No remnant carcinoma in the upper and lower cutting edge was found in pathological examination. The operation time ranged from 2. 92 ～ 4. 67 ( 3. 37 ± 0. 42) hours. Blood transfusion during perioperative period was 0 ～ 6u ( 1.08 ± 0. 93 ) u. Perioperative plasma transfusion was 0 ～ 1400( 103.77 ± 184. 89) ml. The hospital-time was 14 ～ 39 ( 17.64 ±4. 12) days. There were no anastomotic leakage and recurrent laryngeal nerve injury. One case died from respiratory failure, the mortality was 0. 04% ( 1/213). Conclusion Surgical approach in the management of left thoracotomy in the sixth intercostals could extend resection of chest-field lymph node dissection, decrease neck field lymph node dissection. Abdomen-field lymph node dissection reached selected D3. The selected lymphadenectomy procedure had the advantages of small traumas and few complications.

Objective To verify that traditional Chinese medicines have certain price advantages compared with western medicines,and to estimate the rational increase in the compensation proportion of traditional Chinese medicine in the new rural cooperative medical system.Methods Using stratified sampling survey and literature review,the average outpatient and hospitalization expenses in the treatment of common diseases in rural areas were calculated and compared among traditional Chinese medicine,western medicine,and integrated traditional and western medicine.Results For average outpatient and hospitalization expenses,traditional Chinese medicine was lower than western medicine,integrated traditional and western medicine was lower than western medicine.and traditional Chinese medicine was lower than integrated traditional and western medicine.For hospitalization expense,traditional Chinese medicine had a 25.2%lower expense compared with western medicine.The ratios of expenses were statistically calculated,and the mathematical model for the compensation proportions of traditional Chinese medicine and western medicine in the new rural cooperative medical system was put forward.Conclusions In the implementation scheme of new rural cooperative medical system,the compensation proportion of traditional Chinese medicine in outpatient and hospitalization expenses should be increased by 25%and 33%respectively compared with western medicine.
