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.

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.

Objective To evaluate the effect of recombinant human erythropoietin (rHuEPO) on brain injury in the patients undergoing cardiac valve replacement with cardiopulmonary bypass (CPB).Methods Forty-five patients with chronic valvular heart disease,aged 36-62 yr,weighing 42-92 kg,of American Society of Anesthesiologists physical status Ⅱ or Ⅲ,with New York Heart Association of Ⅱ or Ⅲ,undergoing cardiac valve replacement with CPB,were randomly divided into 3 groups (n =15 each) using a random number table:control group (group C),and different doses of rHuEPO groups (EPO1 group,EPO2 group).In EPO1 and EPO2 groups,rHuEPO 40 and 80 IU/kg were injected intravenously before anesthesia induction,respectively.Before anesthesia induction (T0,baseline value),immediately after endotracheal intubation (T1),immediately after aortic cannulation (T2),immediately after cannulation of superior and inferior vena cava (T3),immediately after the beginning of CPB (T4),when each index was decreased to the minimal value during CPB (T5),after rewarming to 36.5 ℃ (T6),immediately after termination of CPB (T7),and at 1 h after termination of CPB (T8),regional cerebral oxygen saturation (rSO2),tissue hemoglobin index (THI),and changes in concentrations of oxyhemoglobin (△ O2Hb),deoxyhemoglobin (△ HHb) and total hemoglobin (△ cHb) in bilateral frontal lobes were recorded.The patients whose minimal rSO2 ≤ 50％ and decrease in minimal rSO2 ≥ 20％ of the baseline value (△rSO2) were recorded.At T0,T8 and 2 h after termination of CPB (T9),venous blood samples were taken for determination of serum concentrations of S100 protein and neuron-specific enolase (NSE) by ELISA.At 1 day before surgery and 8 days after surgery,the patient's cognitive function was assessed using Mini-Mental State Examination,the Digit Span subtest of the Wechsler Adult Intelligence Scale-Revised (WAIS-R),the Digit Symbol subtest of the WAIS-R,the Trailing Making Test (Part A)and the Stroop Color Word Interference Test,while depression and anxiety were assessed by Zung Self-Rating Depression Scale and Zung Self-Rating Anxiety Scale,respectively.The occurrence of postoperative cognitive dysfunction was recorded.Results There was no significant difference among the three groups in bilateral rSO2 and △ cHb,incidence of bilateral rSO2 ≤ 50％ and postoperative cognitive dysfunction,Zung Self-Rating Depression Scale score,and Zung Self-Rating anxiety Scale score at each time point (P＞0.05).Compared with group C,the incidence of left △ rSO2 ≥ 20％ was significantly decreased,the right △ O2 Hb was increased at T6,8,the serum NSE concentrations were decreased at T9,the serum S100 protein concentrations were decreased at T8,and the number of the Digit Symbol subtest of the WAIS-R completed was increased in group EPO1,and right THI was significantly decreased at T2,T3,T5,T7 and T8,right △ HHb was increased at T2 and T3,and the completion time of Stroop color word interference test B was shortened at 8 days after surgery in group EPO2 (P＜0.05 or 0.01).Compared with group EPO1,the incidence of left △rSO2 ≥ 20％ was significantly increased,the right THI was decreased at T2-4 and T6-8,and the left △ O2 Hb at T6-7 and right △ O2 Hb at T8 were decreased in group EPO2 (P＜0.05).Conclusion rHuEPO 40 IU/kg injected intravenously before induction of anesthesia can mitigate brain injury in the patients undergoing cardiac valve replacement with CPB.

Objective To investigate the effects of medium-and long-chain fatty acid triacylglycerols on lipid metabolism in different age's male subjects with hypertriglyceridemia.Methods A randomized double-blind and controlled clinical trial was carried out among 74 male cases with hypertriacylglycerolemia.They were divided into two groups,one group was randomized to taking long-chain fatty acid triacylglycerol oil(LCT),and the other one to medium-and long-chain fatty acid triacylglycerol oil(MLCT).All cases in two groups asked to consume 20～30 g oil daily.Anthrepometric measurements and blood biochemical variables were measured at the initial and final time of the study.Results There were 34 and 33 cases left in LCT and MLCT group,respectively.A greater extent of decrease in the levels of blood TG,TC,apoB,apoA Ⅰ,apoAⅡ,apoC Ⅱ,apoC Ⅲ,apoE and LDL-C in male subjects aged less than 60 years was found in MLCT group than in LCT group after 8 weeks study(P
