Objective To study reasons for conversions to open surgery in gynecological laparoscopic operations.Methods Clinical records of 53 cases of conversions to open surgery out of 1 066 cases of gynecological laparoscopic operations from January 2000 to March 2005 in this hospital were analyzed retrospectively.Results The reasons for conversions included pelvic adhesion in 23 cases,difficulty in myomectomy in 10 cases,malignant tumors in 9 cases,and intraoperative complications in 3 cases,accounting for 43.4%(23/53),18.9%(10/53),17.0%(9/53),and 5.7%(3/53) of the 53 cases,respectively.Conclusions Pelvic adhesion,which leads to difficulties in laparoscopic performance,is the primary reason for conversion to open surgery.Proper patient selection and improved capability for distinguishing benign ovarian tumors from malignant ones can decrease the incidence of conversions.

Success of Sanming's heahhcare reform relies heavily on the government's dominant role.Based on this inspiration,the paper discussed the responsibilities expected of the government in health protection of the people as required by national strategy,public interests and market demands,and presented the corresponding responsibilities of the government in the protection,leadership,scrutiny and management for the sake of public health.In addition the paper recommended on policies to make up for the absence and dislocation of governmental responsibilities,including all-out efforts for legislations in health protection,greater government subsidy for health protection,development of a comprehensive supervision system,and establishment of entities accountable for people's health in general.

Objective To quantitatively observe the actual levels of 4977 bp and 3895 bp mitochon-drial DNA (mtDNA) deletion in healthy human skin of different age, and to explore their relationship with intrinsic aging and photoaging. Methods Seventy-one samples of skin tissue were obtained from healthy volunteers, including 40 samples from UV-protected areas (buttock, thigh, waist or abdomen) and 31 from UV-exposed areas (neck, back of hands, forehead or face). Nuclear and mitochundrial DNA was extracted from these samples. Conventional PCR was performed to detect the incidence of 4977 bp and 3895 bp mtDNA deletion. Then, SYBR Green real-time PCR was applied to quantitatively analyze the target mutations in posi-tive samples. Results Conventional PCR showed that the incidence of both 4977 bp deletion and 3895 bp deletion increased with age. For example, the incidence of 4977 bp deletion and 3895 bp deletion accounted for 47.5% (19/40) and 30% (12/40), respectively in samples from volunteers older than 40 years, signifi-cantly higher than that in those from volunteers younger than 40 years (X2 = 4.673, 6.118, respectively, both P < 0.05). The total incidence of 4977 bp deletion and 3895 bp deletion in UV-exposed areas was 48.4% (15/31) and 32.3% (9/31), respectively, which did not differ from those in UV-protected areas. The results from real-time PCR revealed a positive correlation of the copy number of 4977 10p deletion and 3895 bp deletion with age (rg = 0.907, 0.845, respectively, both P < 0.05). When the UV-exposed area was compared with the UV-protected area, no significant difference was found in the copy number of 4977 bp deletion ( P = 0.264), whereas a higher level of 3895 bp deletion was noticed in UV-exposed area (P = 0.014). Conclu-sions The 4977 bp mtDNA deletion is primarily associated with chronological aging, and might serve as a biomarker for the process of chronological aging of skin. Deletion of 3895 bp mtDNA seems to be more sus-ceptible to ultraviolet radiation.

OBJECTIVE:To establish a HPLC method for the simultaneous determination of blood drug concentration of acetaminophen and phenacetin.METHODS:Diamonil C 18 was used as the chromatographic column,the mobile phase was methanol-water(45∶55),theophyllinum was used as internal standard,the detection wavelength was254nm and the column temperature was set at the room temperature.RESULTS:The minimum determination concentration of acetaminophen and phenacetin was5?g/ml,the calibration curve was linear in a range from5～25?g/ml;The recovery rate of both acetaminophen and phenacetin in this method was more than95%;both the intraday RSD and the interday RSD were less than4.0%.CONCLUSION:The method is rapid and accurate,which can satisfy the needs of the clinic blood drug concentration deter-mination of paracetamol and phenacetin.

OBJECTIVE:To establish a method for determination of Morphine in Pipazhike soft capsules by using SPE-HPLC.METHODS:SPE condition:C18 cartridge.15mL MeOH-water(3∶ 1)and 5mL water were used as elution solvent.RESULTS:Morphine had a good linearity in the rang of 0.233 5～ 1.868 0? g(r=0.999 9).The average recovery rate was 97.6%(RSD=1.2%,n=5).CONCLUSION:This method is simple,accurate,and reproducible,and can be used to effectively control the content of Morphine in Pipazhike soft capsules.
