ABSTRACT
Objective T o explore the num ber of necrophagous flies and seasonal distribution of com m on necrophagous flies at present in B eijing. Methods T he specim ens of necrophagous flies w ere collected by the m ethods of anim al carcass, trapping and feeding. A nd the specim ens w ere observed and counted after the classification and preservation. Results T he necrophagous flies in B eijing belonged to 4 fam i-lies, 9 subfam ilies, 21 genera and 46 species, and 12 species of them w ere the first records in B eijing. T he necrophagous flies had the characteristics of regional and seasonal distribution. Conclusion T he data of seasonal distribution of necrophagous flies and com m on necrophagous flies in B eijing can provide refer-ence for related research.

ABSTRACT
Objective To investigate the fly in relation to cadaver in the area of Guizhou. Method According to entomological investigation method, 12 areas were selected for investigation, where specimens were collected from 10th to 20th in February, May, August and November in a year. Results 37433 sarcosaphagous fly specimens were collected in 12 areas in a year, which were classified into 27 species of 17 genera in 5 families.Conclusion Data on the sarcosaphagous fly species, area- and season-related distribution were obtained, which is reported first time in China. and may form a basis for further study on the development of sarcosaphagous fly and provide reference to estimation of possible season and circumstance when death occurred.
ABSTRACT
Objective To explore the value of laparoscopic operations for early-stage cervix cancer. Methods Eighteen patients with Ⅰ b～Ⅱ a astage cervix cancer underwent extensive total uterectomy combined with pelvic lymphadenectomy under laparoscope (17Ⅰ b cases, 1Ⅱ a case). Concurrently, another 19 patients with the same diagnosis and approximately the same clinical features as the abovementioned 18 cases, as the control group, were treated by open extensive total uterectomy combined with pelvic lymphadenectomy. The operation time, intraoperative blood loss, postoperative recovery and complications of two groups were compared. Results No statistically significant differences were found on mean operation time between the laparoscopy group (272.8 min?80.3min) and open group (226.5 min?66.8min) (t=1.921,P=0.063). The number of removed lymph nodes was 15.6?5.1 in laparoscopy group and 16.8?5.7 in open group, without statistically significant differences (t=0.674,P=0.505). The recovery time of intestine functions in laparoscopy group (34.2 hours) was obviously shorter than that of open group (60.7 hours) (P
ABSTRACT
Objective To evaluate the clinical efficacy of four different operative patterns of laparoscopic hysterectomy: laparoscopically assisted vaginal hysterectomy (LAVH), laparoscopically introfasial subtotal hysterectomy (LISH), laparoscopically subtotal hysterectomy (LSH) and laparoscopically total hysterectomy (LTH). Methods A retrospective analysis on 2272 cases of laparoscopic hysterectomy was carried out, including operating time, blood loss, complication and postoperative recovery. Results For the two groups which preserved cervix, LISH was performed in 1323 cases. The operating time was (91?21) min, blood loss (93?23) ml, complication rate 4.1%. LSH was conducted in 229 cases, with an operating time (70?18) min, blood loss (69?17) ml, complication rate 0. The difference between the two groups was significant (all P0.05). All patients recovered well postoperatively. Conclusions The four operative patterns are ideal for hysterectomy. Young patients should be operated with laparoscopic hysterectomy with preservation of cervix, old patients or patients with CIN should be operated with excision of cervix.
ABSTRACT
Objective To detect CD_(36) expressions in polycystic ovary (PCO), and to explore its correlation with local androgen and insulin at transcription level. Methods From August 2002 to February 2003, 12 patients with asymmetric PCO, 15 primary or secondary infertile patients without endocrine disorders and 8 polycystic ovary syndrome (PCOS) with bilateral PCO were recruited. Extraction of follicular fluid and detection of testosterone(T), dehydroepiandrosterone sulfate (DHEAS), insulin (INS) and androstenedione (A_2) were performed. Relative CD_(36) mRNA expression level of human ovarian inner thecal cells was analyzed by auto image analysis system (IAS) after RT-PCR. Results The level of CD_(36) mRNA expression in thecal cells was 0.24?0.07 in polycystic ovary of PCO group and 0.21?0.05 in bilateral ovaries of PCOS group, respectively, which were significantly lower than 0.83?0.13 in normal ovaries (P
