Objective To study safety and values of laparoscopic surgery in the management of gynecological diseases in senile women.Methods Clinical data between 27 cases of laparoscope surgery(Laparoscopic Group) and 25 cases of open surgery(Open Group) from January 2001 to December 2006 were retrospectively compared.Results The operation time in the Laparoscopic Group(20.0?7.9) min was significantly shorter than that in the Open Group(44.0?7.2) min(t=-11.419,P=0.000);the blood loss in the Laparoscopic Group(21.9?20.0)ml was distinctively less than that in the Open Group(62.6?29.4)ml(t=-5.875,P=0.000);the postoperative pyrexia in the Laparoscopic Group(3 cases) was significantly less than that in the Open Group(12 cases)(?2=8.606,P=0.001);the time to first flatus in the Laparoscope Group(13.9?2.9)h was significantly shorter than that in the Open Group(23.4?4.3)h(t=-9.404,P=0.000);hospital stay in the Laparoscope Group(7.6?0.9) d was significantly shorter than that in the Open Group(10.2?1.2) d(t=-8.882,P=0.000).Conclusions On the basis of intensive treatment of preoperative complications and perioperative monitoring,laparoscopic surgery is an ideal procedure for benign gynecological diseases in senile women.

Objective To determine the efficacy and safety of hysteroscopic resection with dipolar electrodes for submucous myoma of the uterus. Methods By hysteroscopy combined with B-ultrasonography,totally 456 cases of submucous myoma of the uterus were confirmed in our hospital from January 1998 to December 2007. Among the patients,241 cases showed type 0,138 patients were type Ⅰ,and 77 cases were type Ⅱ. In 341 of the cases,the myoma sized 1.0 to 2.0 in diameter,86 cases from 2.1 to 4.0 in diameter,and the other 29 cases had the myoma ranged from 4.1 to 6.0 cm in diameter. Hysteroscopic resection with dipolar electrodes were performed on all the cases,among which microelectrode was used in 341 patients,and ring electrode was employed in 115 cases. Results The operation time ranged from 9 to 55 min with a mean of (32.9?16.7) min. The removed tissues weighed (30.2?8.2) g in average (ranged from 5 to 55 g). During the operation,the patients had 5 to 100 ml blood loss [mean,(48.1?12.7) ml]. No complications occurred during and after the operation. The patients were followed up for three months,during which 431 (94.5%) showed reduced menstruation and decreased menstrual blood loss,only 5 patients (1.1%,all were type Ⅱ) had residual myoma. In this series,totally 42 patients wished pregnancy,15 of them became pregnant in 24 months postoperation. After the treatment,anemia was corrected in 206 patients with the level of Hb increased to a normal range;before the operation,81 patients had menstrual pain,42 of them were relieved and 19 were improved by the operation,while the other 20 showed no changes in the symptoms. Conclusion Hysteroscopic resection with dipolar electrodes is safe and effective for uterine submucous myoma.

Objective To know the levels of polychlorinated dibenzo-p-dioxins(PCDDs),polychlorinated dibenzo-p-furan (PCDFs)and polychlorinated biphenyl(PCBs)in milk and milk powder.Methods From Feb.2007 to Jun.2007,the milk and milk powder samples were collected and PCDDs,PCDFs and PCBs were extracted from the samples by Soxhlet extraction,cleaned up by FMS and quantified by HRGC-HRMS,using isotope dilution methodology.Results PCDDrFs and PCBs were detected in all samples.The mean levels of PCDD/Fs and dl-PCBs TEQ in the milk powder were 0.43 pg/g lipid(median:0.34 pg/g lipid),and in the packed milk were 3.83pg/g)lipid(median:2.04 pg/g lipid).The mean levels of PCDD/Fs and dl-PCBs TEQ in all samples were 2.13 pg/g lipid(median:0.815 pg/g lipid).The levels of PCDD/Fs and dioxin-like PCBs in the detected samples were far below the limitation of EU except of two milk samples,and the levels of PCDD/Fs and dioxin-like PCBs were higher in the packed milk than those in the milk powder.Conclusion Some of the milk and milk powder in the investigated city has been polluted by polychlorinated dibenzo-p-dioxins(PCDDs),polychlorinated dibenzo-p-furan(PCDFs)and polychlorinated biphenyl(PCBs).

Abstract: Objective　To analyze the impact of the flood disaster on the distribution of Oncomelania snails in 2020 in Wuhu City, to provide scientific basis for formulating the "14th Five-Year Plan" for schistosomiasis control and precise prevention and control measures in Wuhu City. Methods　Systematic sampling combined with environmental spot check was used to investigate the distribution of snails in the historical snail's environment, existing snail's environment and suspected snail's environment in Wuhu City. The collected snails were crushed and examined by microscope to understand the death and life of snails and the infection of Schistosoma japonicum, and the density of live snails and other indicators were counted. Results　The historical area of snails was 14 475.24 hm2 in Wuhu City, and the existing area of snails was 4 588.72 hm2, including 4 210.32 hm2 for lake type and 378.40 hm2 for hill type snails. The average occurrence rate of live snails was 14.59%, and the average density of live snails was 0.50 snails/0.1 m2 in Wuhu City. There were 2 745 snail breeding environments, of which 491 were lake type and 2 254 are hill type, accounting for 17.89% and 82.11% respectively. The existing snail area was mainly distributed in the beaches and ditches, accounting for 92.51% and 6.29% of the existing snail area respectively. Some snails were distributed in ponds, paddy fields and other environments. Among all the historical snail habitats, the majority were class Ⅱ and class Ⅲ environments (which still have the basic conditions for snail breeding at present), with a total of 1 739 sites (blocks), accounting for 63.35% of the total environment. No schistosomiasis infected snails have been found, and the newly discovered and recovered snails cover an area of 268.21 hm2 in Wuhu City. Conclusions　The distribution of snails is extensive in Wuhu City, and snails are mostly distributed in beaches, which are vulnerable to the impact of flood disasters. The spread of Oncomelania snails is found in 30 marshlands in 3 counties in this survey. It is necessary to continue to strengthen snail monitoring after disasters, and take class Ⅱ and class Ⅲ environments as key areas for snail monitoring, so as to find, identify and evaluate the risk of schistosomiasis transmission as soon as possible, to avoid or reduce the impact of flood disasters on the process of schistosomiasis control, and promote the process of schistosomiasis elimination.

Purpose　To evaluate the effects of ambroxol on prevention of premature babies with hyaline membrane disease(HMD) with prenatal corticosteroids.　Methods　Premature neonates gestational age 26-36 weeks were divided into two groups,receiving:(1) Ambroxol 30 mg/kg through umbilical vein at birth(group A,n=28) and (2) a control group not given ambroxol (group B,n=35).All the babies were exposed prenatally corticosteroids.　Results　(1) Occurrence rate of HMD in group A was 0%,group B was 11.4%,there was significant difference (P<0.05).(2) Mean fetal age of group A was 32.47+/-4.5 pregnant weeks,group B is 32.86+/-7.1 weeks.No significant difference existed.(3) Different fetal age in gruop B,such as pregnant weeks≤32,33-34,35-36,the HMD rate was separately 28.7%,15.38% and 0%,no case was found in group A.(4) There cases of 12 neonatal asphyxia happened in group B,but none of 6 in group A.　Conclusions　Definite effect can be received by applying ambroxol to prevent premature infant HMD after delivery on the bases of adenotropin before delivery.

Objective To evaluate the pelvic floor function in post-hysterectomy patients. Methods Transperineal pelvic ultrasound was used to observe the pelvic organs in post- hysterectomy patients, and parameters of pelvic floor were measured. Taking the inferior margin of public symphysis as the reference plane,the shape and motion of the proximal urethra and bladder neck were observed at rest and on maximum Valsalva maneuver. Bladder neck-symphyseal distance(BSD) and retrovesical angle were measured. And the bladder neck descent(BND),urethral rotation angle and the rotation angle of the bladder neck were also calculated. Interclass correlation coefficients were calculated to evaluate the consistency of data. Results At rest,the BSD and retrovesical angle were (-2.73±0.37)cm and (119.00±22.40)°, while on maximum Valsalva maneuver was (-0.25±0.67)cm and (114.74±21.50)°,respectively. BND was (2.46±0.59)cm,the urethral rotation angle and the rotation angle of the bladder neck was (70.68±19.91)° and (60.81±17.34) °,respectively. Combined with pelvic ultrasound and clinical manifestations,29 cases of pelvic floor dysfunction after hysterectomy were diagnosed (58.00%, 5 cases of stress urinary incontinence, 8 cases of proctoptoma and 16 cases of bladder prolapse). The consistency was very high in measuring BNS, retrovesical angle at rest and on maximum Valsalva maneuver and BND by different observers. The interclass coefficient was 0.90,0.89,0.91,0.88,0.92,respectively. And the interclass coefficient of urethral rotation angle and the rotation angle of the bladder neck was 0.79, 0.88,respectively. These results showed a good interobserver agreement. Conclusion Transperineal pelvic ultrasound is a simple,reproducible and noninvasive imaging method, which can reveal the position and function of female pelvic organ dynamically and evaluate postoperative pelvic floor function.
