Objective　To timely understand the current status and distribution of nail snails (Oncomelania hupensis) in Tongjiang River channels in Zhenjiang City, providing a scientific basis for achieving the goal of eliminating schistosomiasis. Methods　From 2019 to 2023, nine Tongjiang River channels on the south bank of the Yangtze River under the jurisdiction of Zhenjiang City were selected as the monitoring area. Snail monitoring was carried out onshore and beach nail snails floats in the Tongjiang River channels, nail snails on attachments in hardened areas, snails induced by straw curtains, and snails carried by boats and domestic animals. Results　The monitoring results of shoreline snail from 2019 to 2023 showed that the snail situation in the Tongjiang River channel and its outer river bank remained relatively stable from 2019 to 2020; however, in 2021, under the influence of the Yangtze River flooding disaster in 2020, the area of snails increased significantly. In 2021, the area with snails in the Tongjiang River channel and the outer river bank increased by 45.70% (11.95/26.15) and 100.00% (20.00/20.00) compared to 2020; the average density of nails snails in the Tongjiang River channel and the outer river bank and the emergence rate of snail frames both showed a significant increase, rising by 94.73% (0.18/0.19) and 68.08% (8.68/12.75) compared to 2020, and by 122.73% (0.81/0.66) and 102.78% (43.26/42.09), respectively. The differences in the increase in the occurrence rate of spiked frames in the Tongjiang River channel Chili River and Renmin River were not statistically significant (χ2=0.329, P>0.05; χ2=0.646, P>0.05). From 2022 to 2023, the density of nail snails and the occurrence rate of framed snails in the Tongjiang River channel showed a decreasing trend (F=4.72, P=0.04 and χ2=372.58, P<0.01). The area of nail snails, density of live snails, and occurrence rate of framed snails in the outer river bank showed a decreasing trend (F=13.96, P=0.02; F=23.43, P<0.01; χ2=1 029.69, P<0.01). During the five years, no nail snails were detected in the ancient canal and 11 tributaries. From 2019 to 2023, 180 times of 3 003 kg of floating objects were salvaged, with a total of 148 live snails detected. A total of 17 live snails were captured on attachments in the hardened berm area; a total of 11 live snails were captured by straw curtain snail baiting;112 boats were inspected, and no snails were found; there were 112 boats surveyed, and no snails were found; 97 cattle were observed, and 2 cattle were found to carry 1 live snail on their hooves; 321 sheep were observed, and no snails were found on their hooves; and no infectious snails were found in the monitoring area in 5 years. Conclusions　Nail snails continue to exist in the Tongjiang River channel, and the risk factors for schistosomiasis transmission have not been completely eliminated. It is still necessary to carry out accurate monitoring of the snail situation in the Tongjiang River and the river bank, so as to grasp the risk of transmission in time and take emergency measures.

Objective To silence human gene Set7/9 and screen out stable transfection cell line in hepatocellular carcinoma cell line HepG2 so as to investigate the impact of down-regulation of Set7/9 in cell line HepG2 and provide experimental foundation for studies on the effect of set7/9 in HepG2.Methods The target oligo was designed and synthesized;shRNA interference vector and the control vector were constructed and transfected into HepG2 cells;the stable transfection cells were screened out.Then Real-time PCR and Western blot were performed to detect the silence of Set7/9 according to both gene expression and protein expression level. Results The shRNA interference vector was constructed and transfected into HepG2 cells successfully.Compared with that in the negative control group,the expression of Set7/9 was dramatically downregulated (P < 0.05 ). Meanwhile,the expression of related protein Sirt1 and Suv39h1 was upregulated 8.4 folds and 1.1 fold, respectively.Conclusion Downregulation of Set7/9 expression can upregulate Sirt1 and Suv39h1,suggesting that Set7/9 may affect the activity of HepG2 cell lines.

BACKGROUND:Erythromycin spreads widely in the body with a short period of effective concentrations and has a lot of adverse effects.Therefore,it is necessary to make erythromycin as targeted medicine.OBJECTIVE:To optimize the preparation conditions of erythromycin gelatin microspheres.DESIGN,TIME AND SETTING:An orthogonal controlled test was performed in the Department of Pharmacy,Guangdong Pharmaceutical University from June to December in 2005.MATERIALS:Erythromycin and gelatin.METHODS:According to the emulsion principle,erythromycin dispersed in the gelatin solution.In the process of preparing microspheres,the gelatin solution and oil should form W/O emulsion and then it turned into spheres by solidification.The formation and quality of microspheres were influenced by four factors,namely the concentration of gelatin,dosage of emulsifier,the solidification time and the speed of mixing.The arithmetic mean diameter of microspheres,the drug loading efficiency and the encapsulation efficiency were targets for the survey in this study on the basis of pretests.The best preparation conditions were optimized in accordance with the results of L9 (34) orthogonal tests.The optimized preparation conditions were obtained according to the results of orthogonal tests.MAIN OUTCOME MEASURES:The mean diameter of microspheres,the drug loading efficiency,the encapsulation efficiency,and the orthogonal tests were examined.RESULTS:The optimized preparation conditions of erythromycin gelatin microspheres included 15% gelatin,3.0 mL emulsifier,0.5 hour solidification and mixing at 1 000 r/rain.The erythromycin gelatin microspheres were regular in their morphology.Drug was enveloped in microspheres.The average particle size was (14.15±0.20) μm;the drug loading efficiency and the encapsulation efficiency were (5.83±0.38)% and (65.70±0.56)%,respectively.Over 90.16% of the microspheres was in the range of 7-25 μm;The reappearance of pharmaceutical technology was good.CONCLUSION:The optimized preparation conditions of erythromycin gelatin microspheres are obtained using L9 (34)orthogonal tests.The microspheres prepared meet the requirement of the size for lung targeting.

Objective To evaluate the influence of simple subtalar arthrodesis to the motion and degeneration of midfoot.Methods Data of 37 patients (27 males,10 females) with an average age of 42.6 years who had undergone subtalar joint fusion from January 1996 to August 2011 were retrospectively analyzed.The MOS item short form health survey (SF-36),American Orthopaedic Foot and Ankle Society (AOFAS) midfoot score were used.Midfoot sagittal and coronal motion were measured on ankle radiographs of maximum plantar flexion and dorsiflexion.On sagittal plane,the Meary angle was measured and the bilateral tarsometatarsal joints mobility was compared.On coronal plane,tibio-plantar angles (TPA) on 30 degrees varus slope and 30 degrees valgus slope were respectively measured on the anterio-posterior ankle X-ray films to observe the changes of midfoot activities.Besides,single photon emission computed tomography/computed tomography (SPECT/CT) of bilateral foot and ankle was taken to estimate the degeneration of midfoot joint.Results All the 37 patients were followed-up,with mean follow-up period of 9.2 years.The average SF-36 scores was increased from 34.26± 11.02 points preoperatively to 77.59± 12.57 points postoperatively.The average AOFAS midfoot scores were 86.14± 16.79 points preoperatively and 86.43± 16.70 points postoperatively without any statistical significant difference.On sagittal plane,medial tarsometatarsal joints mobility was limited by 20％.According to coronal plane of varus slope,the average TPA of healthy side and operated side were 61.32° and 64.91°,respectively,so the varus mobility of operated side was limited by 12.5％.While standing on the valgus slope,the average TPA of both sides were 76.54° and 82.28°,which indicated that valgus mobility of operated side was reduced by 42.6％.35.1％ patients of talonavicular joint,56.8％ patients of calcaneocuboid joint,and 27.0％ patients of metatarsal cuboid joint were found mild joint degeneration on SPECT/CT images without any clinical symptoms.Conclusion Subtalar arthrodesis can affect midfoot with less limit of sagittal mobility and more limit of coronal movement.And the lateral joints degeneration is more likely to happen for their compensatory activity.

Objective To explore the effects of melatonin (MT) on the expression of interleukin (IL)-10,interleukin-6 and interleukin-8 as well as the inflammatory reaction and nerve repair after acute spinal cord injury (SCI).Methods One hundred and eight Sprague-Dawley rats were randomly divided into a spinal cord injury group (group A),an MT treatment group (group B) and a sham operation group (group C),each with 36 rats.SCI models were established in the rats of groups A and B using a version of Allen's weight drop method (50gcf at the T12 level).Group C had removal of the lamina only.Ten minutes later,group A was injected with 5％ ethanol in saline (the MT solvent) and group B with 100 mg/kg of melatonin preparation.At 6,12,18 and 24 hours,IL-6,IL-8 and IL-10 levels in serum were detected in 6 rats of each group.At 18 hours post-surgery,spinal cord specimens were taken from 6 rats of each group for hematoxylin eosin staining,morphological examination and immunohistochemical SP detection of IL-10 expression.Results The specimens of group A showed inflammatory reaction and ulceration at 48 h; groups B and C had no ulcers.Group B showed the highest levels of IL-10 in serum and IL-10 mRNA in the spinal cord,while group C showed the lowest level.The differences were statistically significant.Group A had the highest levels of IL-6 and IL-8 and group C had the lowest.The difference between group B and groups A and C was significant.The morpho-logical observation showed that after melatonin treatment the IL-10 levels in the spinal cord's central canal and around the gray matter improved.Conclusions Melatonin can improve nerve lipid peroxidation and inflammatory reaction in the treatment of spinal cord injury by increasing IL-10 expression and inhibiting IL-6 and IL-8 expression.
