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 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.

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.

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).

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 evalute the value of spiral CT in diagnosis and treatment of chronic suppurative otitis media.Methods Sixty-five cases including seventy-nine ears underwent the direct axial plane and coronal multiplanar reformation and three-dimensional reconstruction of auditory ossicular chain in chronic suppurative otitis media spiral CT imaging of temporal bone. Results The direct axial plane and coronal multiplanar reformation in diagnosing of the chronic suppurativeotitis media were correspondent,but in showing of the most middle ear structure were difference. Three-dimensional images was superior to axial and coronal MPR images in showing of the change of malleus and incus,the contrary situation in showing stapes. Only 3D image may not select application for definition.The rate of agreement between spiral CT diagnosis by combination of three different imaging methods and definition of chronic suppurative otitis media and operative findings(89.9%～97.5%) were higher, false positive rate(2.9%～6.0%) and false negative rate(0～14.6%) of the CT diagnosis were lower.Conclusion Combination of three different imaging methods(axial images, coronal MPR images and three-dimensional images of the ossicular chain) can improve the value of the spiral CT diagnosis and therapy of chronic otitis media.

Objective To explore the association between the infection rate of Helicobacter pylori (Hp) and intake frequency of capsicum in dietary pattern. Methods A total of 914 health check-up participants were recruited from Tianjin Medical University General Hospital (male: 510,female:404). All participants were asked about the intake frequency of capsicum. Diagnostic criteria of the Hp infection included positive C13 breath test. Results The intake frequency of capsicum was ≥2 times/week, 1 time/week and <1 time/week. The infection rate of Hp was 56.08%, 49.04% and 48.29%. After adjusting for covariates, compared with the≥2 times/week, the odds ratios(95%confidence interval)of intake frequency of capsicum 1 time/week and <1 time/week: the frequency of capsicum intake ≥2 times/week was 1.00 (reference), the frequency of capsicum intake 1 time/week was 0.57(0.33-0.97) and the frequency of capsicum intake<1 time/week was 0.69(0.42-1.14) in men;the frequency of capsicum intake≥2 times/week was 1.00 (reference), the frequency of capsicum intake 1 time/week was 1.01(0.54-1.88), and the frequency of capsicum intake<1 time/week was 0.71(0.41-1.23) in women. Conclusions This study found that food intake frequency of capsicum≥2 times/week was associated with the infection rate of Hp in men. But similar relationship was not observed in women.

Objective To investigate the oxalate-degrading and growth abilities of lactic acid bacteria coming from yoghourt in vitro culture broth. Methods The species of lactic acid bacteria obtained from 6 brands of yoghourt were identified. Different brands of yoghourt were separately cultured in broth and incubated at 37 ℃,5% CO2 for 48 h, getting the concentration of lactic acid bacteria through slab counting method. The brand of yoghourt with the highest quantity of bacteria was chosen as the study subject. Three species of bacteria and the mixture bacteria obtained from the chosen brand of yoghourt were cultured separately for 72 h in MRS broth which contained three different concentrations of ammonium oxalate, and the broth without inoculating of bacterium was prepared as control. The amount of bacteria in culture was detected, the concentration of ammonium oxalate was detected through photometric determination of oxalic acid by its catalytic reaction of methyl red by potassium chromate. Results Three species of lactic acid bacteria (L.bulgaria, L.acidophilus and L.thermophilus) were detected in each brand of yoghourt. The quantity of bacteria in Weiquan yoghourt is the highest. After 72 h incubation, the concentrations of oxalate in all the broths containing bacteria were lower than those in the control. L.acidophilus showed the best degrading activity. The higher the concentration of oxalate was, the bigger the amount of oxalate degraded was, the smaller the percent of degrading was, and the less the growth ability of bacteria was. Conclusion All the species coming from yoghourt have the ability of oxalate degrading, which increases with the concentration of oxalate in culture.But the high concentration of oxalate restrains the growth of bacteria.
