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 study the effect of arsenic trioxide (As2O3) on human pancreatic cancer cell proliferation and apoptosis (mainly early stage) in vitro. Methods: SW1990 cells line were trea ted with As2O3 at different concentration. Cell proliferation was evaluated by MTT and apoptosis by Annexin-Ⅴ-fluostaining, electron-microscopy, flow cytometry and immunocytochemical staining of Bcl-2 and Bax. Results: As2O3 and cisplatin had the same cytotoxity on SW1990. The cytotoxic effe ct on tumor cell was produced by induction of apoptosis. Twelve hours after cult ure with 10 μg/ml As2O3, much more SW1990 cells went into apoptosis than t he control. The apoptosis rate reached 24% after 48 h with the similar concentra tion of As2O3. Immunohistochemical study revealed that the expression of Bcl -2 was decreased after treated with As2O3. Conclusion: As 2O3 can depress the proliferation of SW1990 in vitro, mainly through the i nduction of apoptosis, and it is a potential agent for pancreatic cancer chemoth erapy.

Objective To observe the effect of power-assisted functional electrical stimulation (PAFES)therapy on ankle joint function recovery in stroke patients.Methods Ninety hemiplegic stroke patients were randomly and evenly divided into a control group,a PAFES group,and a neuromuscular electrical stimulation (NMES)group.All groups received conventional rehabilitation training.PAFES group adopted PAFES treatment on affected lower extremities and NMES group was given the NMES therapy on the tibialis anterior of the affected lower limbs,in addition to conventional rehabilitation training.The active range of motion (AROM) of ankle dorsiflexion,FuglMeyer motor assessment (FMA),Barthel index (BI) and Ankle flexion and extension movement (AFEM) in 10 seconds were evaluated before the trial and after 4 weeks treatment.Results After treatment,there were significant differences in the AROM of ankle dorsiflexion,FMA,BI and AFEM (P ＜ 0.05) compared with before treatment within each group.The improvement of AROM of ankle dorsiflexion in PAFES group (8.19 ± 3.39) ° and the values in NMES group (8.96 ± 3.68) ° were to a significantly greater extend than control group (3.88 ± 4.10) ° (P ＜0.05) ; the improvement of FMA and BI in PAFES group was also superior to those in NMES group and control group (P ＜ 0.05).Conclusion The intelligent PAFES therapy could help improve AROM of ankle dorsiflexion,the motor function of the affected lower extremity and the ability of the activities of daily living in stroke patients.

The clinical and pathological materials of 83 cases of prostatic carcinoma (PC) were reviewed retrospectively and the tissue specimens of PC were marked with prostate-specific antigen (PSA). According to the criteria of Dhom's classification of prostatic carcinoma. 66 cases out of the 83 (79. 5%) were of the common variety of PC, 14 cases (10. 9%) were of the rare variety and 3 cases (3. 6%) could not be classified with Dhom's method. Among the 66 cases of common prostatic carcinoma, 41 cases (49. 4%) exhibited a pathological structure of u-riiforrn pattern and 25 cases (30. 1%) of pluriform pattern. Well-differentiated adenocarcinoma, cribriform carcinoma and carcinoid of the prostate were strongly positive to PSA marking; poorly-differentiated adenocarcinoma and almost all the prostatic carcinomas of the rare variety and with the structure of pluriform pattern were positive or weakly positive; undifferentiated solid carcinoma and small cell carcinoma were very weakly positive; and squamous cell carcinoma was negative. In addition, other methods for the pathological classification of prostatic carcinoma used currently at home and abroad were compared and discussed.

Objective To obtain the fusion genes of several human orphan G protein coupled receptors (oGPCRs) with Gi1α subtype of G protein and their expression system. Methods The whole open reading frames of GPR45, GPR85, GPR174 and Gilα were cloned by RT-PCR from HepG2 cDNA separately,and the corresponding fusion genes were amplified by overlap extension PCR. Then, the fusion genes-containing pBacmids were successfully constructed with the Bac-to-Bac baculovirus expression system indicated by specific transposition and virus recombination. The insect Sf9 cells were transfected with pBacmid-oGPCRs-Gi1α, and the supernatant containing recombinant virus was harvested. With the supernatant, insect Sf9 cells were infected under an optimized condition (MOI=5, infection time=72 h) and the fusion proteins were prepared and detected by Western blotting.Results The three fusion genes of GPCR45, GPR85 or GPR174 with Gi1α were obtained. The corresponding fusion proteins could be properly prepared in Sf9 cells.Conclusion Human oGPCRs could be fused with Gilα, and the fusion genes could be expressed using the Bac-to-Bac baculovirus expression system in insect Sf9 cells.

Objective To investigate the changes in cortisol (COR) secretion in the acute phase of traumatic brain injury (TBI) .Method Seventy-five patients admitted to the hospital at 2-24 h after TBI were divided into 3 groups based on the Glasgow Coma Scale score: mild TBI group (group TBI1, n = 30), moderate TBI group (group TBI2, n = 12) and severe TBI group (TBI3, n = 33). Thirteen patients with cervical spondylosis or osteoma of the skull (admitted to the hospital at the same period) were regarded as control group (group C). Venous blood samples were taken on the first day after admission to measure the serum concentrations of total COR, adrenocorticotropin (ACTH) and corticosteroid-binding globulin (CBG). Free COR concentrations and free COR index were calculated. High blood COR was recorded. Result Compared with group C, the serum concentrations of total COR and ACTH, free COR levels and free COR index were significantly increased in TBI1, TBI2 and TBI3groups (P ＜ 0.05). The parameters mentioned above were significantly higher in TBI2 and TBI3 groups than in TBI1 group ( P ＜0.05). There was no significant difference in serum CBG concentrations among the four groups.The incidence of high blood COR was significantly higher in TBI1, TBI2 and TBI3 groups than in C group, and in TBI3 group thanin TBI1 and TBI2 groups (P ＜0.05). Conclusion COR secretion is increased in the acute phase of TBI and the level of COR secretion is related to the severity of brain damage.
