Objective To investigate the genetic association between mutation in cytochrome P450 1A2 (CYP1A2) gene and Erxian suop response. Methods Forty-eight patients with male climacteric syndrome of both Yin and Yang deficiency received a treatment of erxian suop with three months. The severity of symptoms and responses to Erxian suop were quantizated by the method of Department of Psychology in Istanbul Bosphorus University and Clinical Research Guidance Principle on New Drug of Traditional Chinese Medicine published by China. A single nucleotide polymorphism (SNP) at position 2964 (G-A) of CYP1A2 gene were identified by polymerase chain reaction (PCR) in order to analyse the relationship between Erxian response and CYP1A2 single nucleotide polymorphism. Results Statistical analysis showed there was no significant difference among genetype and genetype distribution of CYP1A2 G2964A between the patients and control group. The genotype of the 16 patients among 32 effective patients was G/G (56.25%). The genotype of the 11 patients among 16 ineffective patients was G/A (68.75%). There was no significant difference in symptoms, physical sign between the two groups at the pre-treat and post-treat. Also the two groups had no significant difference among the score of major symptoms and hyposymptoms. Conclusion The patients with genotype of G/G have higher efficiency, while with genotype of G/A have lower efficiency among patients with CYP1A2 G2964A gene when treated with erxian soup.

Objective To investigate the effects of children's mentality on mental symptoms during recovery period of ketamine anesthesia. Methods According to the mentality, forty-five children undergoing smalminor surgery were assigned into active group, stable group and fretful group with 15 cases each. Child was anaesthetized by ketamine alone. RP, BP, HR and SpO_2 were recorded at the end of operation, 5,10 and 30 min after operation. Meanwhile the expression, feeling, behavior, talking and activity were observed. Results RR, BP, HR in active group and fretful group were significantly higher than those in stable group. There was a significant difference in the expression, feeling, behavior, talking and activity among three groups. Conclusion Children's mentality has a significant effect on mental symptoms and hemodynamics during recovery period of ketamine anesthesia.

The self-made high sensitivity and selectivity micro-biosensor was applied to monitor the change of dopamine in cerebral nucleus in rats in vivo. The micro-biosensor was prepared and used to detect dopamine level in vitro and monitor the dynamic change of dopamine in different cerebral nucleus in vivo. The results showed the lowest concentration of dopamine that could be detected by the biosensor was 32.5 nmol/L. Its positive peak was significantly different from that of AA, 5-HTP and E. The biosensor could keep working for monitoring the dopamine concentration in the cerebral tissue for more than 10 h. It was concluded that the microsensor has high sensitivity and selectivity to dopamine and can be used to dynamically monitor the change of dopamine in vivo.

Objective To explore the change of serum amino acid serum in patients with liver cirrhosis and liver cancer, and its significance.Methods The serum amino acids of 46 patients with liver cirrhosis and 44 patients with liver cancer were examined with analyzer of Hitachi 835.Results In the case of patients with liver cirrhosis, the levels of glutamic acid, cystine, methionine and tyrosine in serum were significantly increased (P＜0.01),while, the level of phenylalanine in serum was obviously increased (P＜0.05). When it came to patients with liver cancer, the levels of serum threonine, tyrosine and phenylalanine were significantly increased (P＜0.01), the level of serum serine was obviously higher (P＜0.05). The level of BCAA/AAA (branched chain amino acids/aromatic amino acid) in the two groups was lower than that in the normal control group (P＜0.01). The levels of serum valine and leucine were lower than those in the normal control group (P＜0.05).Conclusion Analyzing the levels of serum amino acids has a certain significance for diagnosing and treating patients with liver cirrhosis and liver cancer.

The ancient discussion and modern clinical application regarding Yingxiang (LI 20) and Neiyingxiang (EX-HN 9) in acupuncture verses are explored. Acupuncture verses are the summary of clinical experiences of acupuncture scholars in the past dynasties, of which the records on application of Yingxiang (LI 20) and Neiyingxiang (EX-HN 9) mainly focused on nasal, facial and head-eye diseases, which is characterized with overall summarization, brilliant exposition, simple language, and distinctive characteristics. Nowadays, based on the ancient usage, the clinical application about these two acupoints is continuously developing. If the ancient acupuncture verses could be understood thoroughly, the clinical practice could be better guided and its effects could be improved.

An introduction to the practice of introducing the“ surgeon qualification admittance system”in the hospital and a description of its management framework,basic principles,rules of classification for surgical operations,application and approval procedure,and supportive management regulations.The authors hold that this system has normalized behavior of medical activities,clarified operation authorities of medical doctors at various levels,and intensified the awareness of risk exposure.Therefore this system can safeguard the quality and safety of surgical operations and its efficiency to a great extent,in addition to better building the team and backup forces.

Objective To optimize supercritical extraction technique from four medicinal materials, which are the part components in the recipe of Keganliyan Oral Liquor and are extracted traditionally for essential oils. Methods Extraction ratio and menthol extraction quantity were taken as evaluated indexes. Supercritical extraction technique was researched with orthogonal tests, gas chromatography, and SAS statistic. Results Within the test levels, temperature and time showed evident effect on extraction ratio and menthol extraction quantity, while pressure did not show any evident effect on them、 The preferable technique to extraction ratio is temperature at 55 ℃, time for 120 min, and extracted pressure at 27 MPa; and the preferable technique to menthol extraction quantity is temperature at 45 ℃, time for 120 min, and extracted pressure at 22 MPa. Conclusion The optimized supercritical extraction technique for Keganliyan Oral Liquor is feasible.

Objective To evaluate the effect of double stapling technique for sphincter preservation operation in mediate-low rectal carcinoma.Methods The resection through double stapling technique for sphincter preservation approach was performed on 30 patients with mediate-low rectal carcinoma from January 2004 to November 2007.The distance between the anal verge and the lower margin of the tumor was 4～8cm(averaged 6.5 cm),including 22 patients in Dukes A stage,6 Dukes B and 2 Dukes C.Results Fecal continences were preserved successfully in all patients.2 cases had got anastomotic narrowing(6.6%) after operation.At a median follow-up of 46 months,two patients had local recurrences(6.6%).There was no urinary dysfunction in this series.Conclusion Double stapling technique for sphinceter preservation operation was feasible and safe,provide a original operative style for mediate-low rectal carcinoma.

Objective To evaluate the effect of procaine on prevention of skin slap necrosis after modified radical mastectomy in breast cancer.Methods 106 breast cancer patients were randomly divided into treatment and control groups.In the treatment group,procaine(1% 100ml diluted in 300ml mormal saline,42℃)were compressed under the skin flap in operation,the control group received same amount of normal salin instead.The rates and sizes of skin flap necrosis were obeserved and compared.Results There were 13 cases suffured from skin flap necrosis among 106 breast cancer cases who received surgery operation.The rate of the flap necrosis in treatment group was5.76%(3/52),and the control group was 18.51%(10/54),there was significant difference(P
