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] The article explores and analyses the clinical dialectical experience of my postgraduate tutor in the treatment on chronic abdominal pain of children. [Methods]From following professor Sang Gao clinical studies,summarize the experience and thoughts of treating chronic abdominal pain of children,and with a case. [Results]My tutor believes that the pathogenesis of chronic abdominal pain of children caused by weakness of middle energizer, disorder of Qi, which lead to the spleen deficiency and qi stagnation, to cure the disease must treat with liver and spleen together, with activating the spleen and regulating the liver, harmonizing stomach and relieving pain as a rule which can achieve good effect. [Conclusion] Activating the spleen and regulating the liver is an effective treatment, it is worthy of in-depth study and promotion.

Objective:To develop the College Students'Career Adaptability Questionnaire(CSCAQ)and test its validity and reliability.Methods:Based on the theoretical construction of Savickas for career adaptability and the open questionnaire survey in 136 college students,this study defined the construct of CSCAQ,and compiled the pre-liminary questionnaire.A sample of 935 subjects coming from 6 colleges was investigated with preliminary ques-tionnaire,and the data were used for item analysis and exploratory factor analysis (EFA).A sample of 1273 sub-jects coming from 8 colleges was investigated with formal questionnaire,and the data were used for confirmatory factor analysis (CFA)and the homogeneous reliability.The criterion validity was tested in 437 subjects with CSOAQ.The test-retest reliability was tested in 110 subjects 4 weeks later.Results:The CSCAQ was composed of 35 items in six factors,which were career control,career curiosity,career concerns,career confidence,career adjust-ment and career interpersonal,and the six factors explained 47.89% of the variances.Furthermore,the result of CFA indicated that the model fitted the data with well construct validity(χ2 /df=3.24,GFI =0.92,NFI =0.85,CFI=0.89,IFI =0.89,TLI =0.88,RMSEA =0.04).The CSCAQ and its factors scores were positively correlated with the CSOAQ scores (r =0.29 -0.85,Ps <0.01).The Cronbach αcoefficients were 0.90 for the total questionnaire and 0.64 -0.79 for the 6 factors.The test-retest reliability were 0.92 for the total questionnaire and 0.74 -0.82 for the 6 factors.Conclusion:It suggests that the College Students'Career Adaptability Questionnaire(CSCAQ)is reliable and valid enough to be applicable to measure college students'career adaptability.
