Purpose To study the cytopathologic features of CT-guided percutaneous lung biopsy samples and to evaluate the role of cytopathology in the diagnosis and staging of lung carcinomas, as compared to histopathology. Methods Four-hundred twenty-five specimens were collected by CT-guided percutaneous lung biopsy which were also confirmed by histological diagnosis. Direct smears were performed for each case. Cytological and histological examination was carried out. Results The sensitivity, specificity, false positive rate, false negative rate and accuracy of cytopathology in diagnosing lung carcinomas by CT-guided percutaneous lung biopsy was 86. 6% (264/305), 100% (120/120), 0 (0/120), 13. 4% (41/305), 90. 4% (384/425), respectively. Overall 51. 1%(135/264) of the cases were precisely typed, including 77. 6% (83/107) of adenocarcinoma, 76. 9% (40/52) of squamous cell car-cinoma and 75. 0% (9/12) of small cell carcinoma. Conclusions Cytopathology of CT-guided percutaneous lung biopsy specimens is sensitive and accurate for diagnosing pulmonary carcinomas. In some cases, the lung carcinoma can be precisely typed. Therefore, it is useful for diagnosing and staging lung carcinomas.

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.

ObjectiveTo investigate the effect of clinical pathway teaching methord in nursing practice teaching. Methods80 junior college nursing students were randomly divided into control and experimental groups. Traditional clinical teaching method was given to control group, while the clinical pathway teaching method was given to observation group. Scores of comprehensive quality after departmental rotation and satisfaction rates of nursing students to teaching method in these two groups were evaluated. ResultsThe experimental group was significantly better than the control group ( P＜0.05 ), and the difference was statistically significant. ConclusionThe clinical pathway can significantly improve the quality of nursing practice teaching.

Objective To investigate the relationship between the apoptosis,expressions of Bcl-2 and Bax protein in perihematomal brain regions of rats and neurologic dysfunctions after intracerebral hemorrhage (ICH). Methods Seventy Sprague-Dawley rats were divided randomly into two groups:an experimental group and a control group.A model of ICH was established by injection of 0.5 U bacterial collagenaseⅦinto the caudate nucleus in the rats.Neurological impairment was evaluated at 6 h,12 h,24 h,48 h,72 h,7 d and 14 d after 1CH,respectively, before the rats were sacrificed.TUNEL method was used to detect apoptosis,and SP method to detect expressions of Bcl-2 and Bax protein in the perihematomal brain tissues.Results Neurological impairment occurred in all the rats after ICH,and peaked at 48 h after ICH.The apoptosis and expressions of Bcl-2 and Bax protein were peaked at 48 h,6 h and 48 h after ICH,respectively.Conclusion The degree of the neurological impairment after ICH is parallel to that of the apoptosis.Apoptosis may play an important role in neurological impairment after ICH.

Objective: To observe the clinical efficacy of heat-sensitive moxibustion for adjuvant treatment of depression in Parkinson disease and explore its mechanism. Methods: A total of 80 patients with Parkinson disease coupled with depression were randomized into an observation group and a control group, with 40 cases in each group. The control group was treated with levodopa and benserazide hydrochloride tablets and paroxetine tablets, while the observation group was treated with heat-sensitive moxibustion on the basis of the medications in the control group. The treatment course was 2 months. The Hamilton depression scale-17 (HAMD-17), unified Parkinson's disease rating scale (UPDRS) and Parkinson's disease quality of life questionnaire-39 (PDQ-39) were scored before and after the treatment, and the efficacy was evaluated after treatment. Levels of patients' serum dopamine (DA), 5-hydroxytryptamine (5-HT), tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) were detected before and after the treatment. Results: After treatment, the total effective rate of the observation group was higher than that of the control group (P<0.05). The HAMD-17 scores in the two groups decreased significantly after treatment (both P<0.05), and the score in the observation group was obviously lower than that in the control group (P<0.05). The component scores and total scores of UPDRS in both groups decreased significantly (all P<0.05), and the scores in the observation group were lower than those in the control group (all P<0.05). The score of PDQ-39 in the observation group decreased significantly (P<0.05), and was lower than that in the control group (P<0.05). After treatment, the serum DA and 5-HT levels in the observation group increased significantly (both P<0.05) and the TNF-α and IL-6 levels decreased significantly (both P<0.05), which were statistically different from those in the control group (all P<0.05). Conclusion: Heat-sensitive moxibustion has certain auxiliary effect in treating depression in Parkinson disease, significantly improving clinical symptoms and the quality of life, which may be related to the up-regulation of DA and 5-HT levels and down-regulation of TNF-α and IL-6 levels.
