ABSTRACT
Data of 55 cases of gastric neuroendocrine neoplasms (G-NENS) with diameter ≤12 mm in the First Affiliated Hospital of Zhengzhou University from August 2014 to August 2019 were retrospectively analyzed. According to the methods of endoscopic resection, the patients were divided into two groups: the endoscopic mucosal resection with a cap (EMR-C) group (35 cases) and the endoscopic submucosal dissection (ESD) group (20 cases). The results showed that the success rates of operation, the whole resection rates and the complete resection rates were all 100.0% in the two groups. Compared with the ESD group, the EMR-C group had a shorter median operation time (12.00 min VS 28.35 min, P<0.001), less mean hospitalization costs (21 165.19 yuan VS 28 400.35 yuan, P=0.004), and a similar overall incidence of complications [2.86% (1/35) VS 0, P=1.000]. By March 2020, the recurrence rate of EMR-C group and ESD group were 28.6% (10/35) and 15.0% (3/20), respectively, without significant difference ( P=0.418). It is suggested that for G-NENS with diameter ≤12 mm, without muscular invasion, lymph node metastasis or distant metastasis, EMR-C and ESD are both safe and effective, but EMR-C has more advantages in terms of operation time and hospitalization costs.
ABSTRACT
Objective:To compare the clinical efficacy of anti-reflux mucosectomy (ARMS) and endoscopic cardial constriction ligation (ECCL) on treatment of gastroesophageal reflux disease.Methods:A retrospective study was conducted on the data of 48 consecutive patients with gastroesophageal reflux disease, who underwent ARMS or ECCL at the First Affiliated Hospital of Zhengzhou University from December 2015 to August 2018. Twenty cases were in the ARMS group and 28 cases in the ECCL group. The short-term and long-term efficacies were compared between the two groups.Results:The success rate of operation was 100.0% in the both groups. The operation time of the ECCL group was significantly shorter than that of the ARMS group (8.43±1.59 min VS 34.05±12.35 min, t=-9.227, P<0.001). After 2 months follow-up, the symptom improvement rate of the ECCL group and the ARMS group was 89.3% (25/28) and 60.0% (12/20), respectively ( χ2=4.128, P=0.042). The GERD Q score of the ECCL group was significantly lower than that of the ARMS group (6.24 ±1.22 VS 7.35±1.79, t=-2.400, P=0.023). One year after operation, there were no significant differences in the symptom improvement rate, GERD Q score, DeMeester score and the time percentage of pH<4 between the two groups ( P>0.05). Conclusion:The long-term clinical effect of ARMS and ECCL is similar, but the short-term clinical effect of ECCL is superior to ARMS.

ABSTRACT
OBJECTIVE To identify the mental state of laryngopharyngeal reflux disease (LPRD) patients by analyzing anxiety scale and depression scale. METHODS The LPRD patients who received treatment in Fuzhou General Hospital were studied. The healthy volunteers were recruited as control group. Self-rating Anxiety Scale (SAS) and Self-rating Depression Scale (SDS) were used to get the individual scores. Mental states of LPRD patients were finally studied through statistical analysis. RESULTS The scores of anxiety and depression in patients with LPRD were significantly higher than those in control group (anxiety score 50.59±7.24 vs 38.76±7.70, depression score 52.90±7.14 vs 40.63±8.17). The incidence of anxiety and depression in patients with LPRD were significantly higher than that in control group (anxiety rate 56.68％ vs 9.80％, depression rate 50.98％ vs 11.76％). Significant association was detected between ref lux symptom index score and anxiety or depression score in patients with LPRD(r =0.786, r =0.736, P ＜0.05). Significant association between LPRD and anxiety and depression were concluded. CONCLUSION The results showed that the patients with LPRD are more prone to be anxiety and depression mental state than healthy control group, and the severity of LPRD symptoms is significantly correlated with the anxiety and depression. This suggests that the patient's mental state should also be emphasized as well as antacids treatment.
ABSTRACT
Objective To compare the long-term efficacy and complications of peroral endoscopic circular myotomy and full-thickness myotomy for patients with achalasia of cardia. Methods A retrospective analysis was performed on the data of 53 patients with achalasia of cardia, who underwent peroral endoscopic myotomy in the First Affiliated Hospital of Zhengzhou University from June 2012 to December 2014 and were followed-up regularly.Twenty-one patients underwent circular myotomy, and the other 32 patients underwent full-thickness myotomy. The postoperative long-term efficacy and gastroesophageal reflux complications of the two groups were compared. Results The effective rate of the circular myotomy group and the full-thickness myotomy group was 90. 5%( 19/21) and 100. 0%( 32/32), respectively ( P＝ 0. 152). There were no significant differences between the two groups on postoperative Eckardt scores, lower esophageal sphincter pressure and 4 s integrated relaxation pressure ( P ＞ 0. 05 ). The incidence of clinically relevant gastroesophageal reflux of full-thickness myotomy group was higher than that of circular myotomy group (40. 6% VS 14. 3%, χ2＝4. 174, P＝0. 041). Conclusion The long-term efficacy of circular myotomy is similar to that of full-thickness myotomy, but the incidence of clinically relevant gastroesophageal reflux is higher in full-thickness myotomy.
ABSTRACT
Objective To investigate that brucein D (BD) possesses potent anti-colon cancer activity by inhibiting proliferation and inducing apoptosis in colon adenocarcinoma cell.Methods After human colon cancer cell line PANC-1 was treated with BD (0,5,10,20,30,80)μmol/L for 24,48,72h,the cell proliferation was detected by cell counting kit-8 (CCK-8)assay.The apoptosis of colon cancer cells was detected using Annexin V-FITC/PI.The protein expressions of JNK and p-JNK were detected using Western blot.Results After human colon cancer cell line PANC-1 was treated with BD for 24,48,72h,the cell survival rates decreased lower and apoptosis rate increased in concentration-and time-dependent manners.AS the concentration of BD got higher or the time got longer,the protein expression of JNK was down-regulated and that of p-JNK up-regulated significantly.In vivo,with the prolonged administration,the mean volume of xenograft tumor grew slowly.The protein expression of JNK was down-regulated and that of p-JNK up-regulated significantly in colon xenograft tumors cells.Conclusion With the increase of time and BD's concentration,the survival rates of colon cancer HT29 cells could be lower.Instead,the apoptosis rate has increased in a concentration-time-dependent manners.
ABSTRACT
Objective:To explore the effect of the BPPV precision manipulation treatment. Method:With 3D SLICER software we segment structure such as semicircular canal, eye ball, orbital and ear rod from MRI or CT volume data of patients which underwent MRI or CT scaning of inner ear, for measuring the spatial direction of semicircular canals and building semicircular canal modules with standard space coordinate system and embedding into 3D PDF files. Result:With the slice that divide the semicircular canal equally as the semicircular canal plane and the eyeball as reference object to determine whether it is symmetric, it is not only intuitive but also reliable for measuring the angle between the posterior semicircular canal. 3D PDF is intuitive, rotation angle can be adjusted according to the individual differences in the process of manipulation treatment, to observe and demonstrate the theoretical reduction effect before the actual operation. Conclusion:By reconstruction the three-dimensional semicircular canal structure from the inner ear image data of patients and measurement of the semicircular canal space direction, it is of a certain significance for BPPV precision manipulation treatment.

ABSTRACT
<p><b>OBJECTIVE</b>To analyze the results of the first-stage toxicological evaluation of 1 502 pesticide samples.</p><p><b>METHODS</b>The classification of the 1 502 pesticide samples was analyzed, and the experimental results of the samples in different years were compared.</p><p><b>RESULTS</b>Most of the 1 502 pesticide samples were insecticides, accounting for 52.5% of all, followed by bactericides and herbicides. In the 5 years, the proportion of biogenic insecticides showed a significant rising trend (χ² = 11.426, P < 0.05). The proportion of single pesticides was 65.8%; mixed pesticides accounted for 32.7%; original pesticides accounted for only 1.5%. From 2008 to 2012, most pesticides had low toxicity, regardless of the exposure route (via the mouth, skin, or respiratory tract). Acute oral and dermal toxicity tests showed that pesticides with moderate toxicity declined year by year (oral exposure χ² = 18.036, P < 0.01; dermal exposure χ² = 40.482, P < 0.01). There was a small proportion of pesticides with high toxicity. We did not detect any pesticide with extreme toxicity. Acute skin irritation and eye irritation test showed an upward trend in proportion of non-irritating pesticides (χ² = 77.110, P < 0.01; χ² = 12.693, P < 0.05), while the proportion of medium-irritation pesticides decreased significantly (χ² = 18.941, P < 0.01; χ² = 13.129, P < 0.05). Sensitization test showed that all samples were weak sensitizers.</p><p><b>CONCLUSION</b>The major type of investigated pesticides was insecticide. Most samples were single pesticides, and there was a certain proportion of mixed pesticides. Novel pesticides such as bio-pesticides are the development tendency. The tested pesticides were mainly low-toxicity pesticides, with a certain proportion of medium- and high-toxicity pesticides. Personal protection should be strengthened during production and use of pesticides.</p>

<p><b>OBJECTIVE</b>To explore the immune response of silicotic rats to sheep red blood cells(SRBC).</p><p><b>METHODS</b>Silicotic rats were immunized with SRBC by tracheal instillation(Group 1) or intraperitoneal injection (Group 2), and non-silicotic rats were immunized by tracheal instillation as normal control(Group 3). The levels of serum hemolytic index(HC50) were measured on 7, 12, 20, 25, and 32 days after primary immunization and 5, 12, 15 days after the second immunization. Special anti-SRBC IgG was measured with ELISA(A490 nm) on 12, 20, 25, 32 days and 5, 12, 15, 27 days respectively. Delayed-type hypersensitivity(DTH) to SRBC was measured 20 days after second immunization and DTH reaction was determined at 24, 48, 72, and 96 h after administration. Total cell count and cell populations in the bronchoalveolar lavage fluid(BALF), lung associated lymph node(LALN) and spleen weight, special IgG secreted from spleen cells were measured at the end of the experiment.</p><p><b>RESULTS</b>The HC50 of Group 1(47.4 +/- 1.0, 52.2 +/- 4.6, 31.1 +/- 11.9, 43.8 +/- 3.5, 33.6 +/- 16.8, 49.0 +/- 2.3, 92.9 +/- 20.2, 87.7 +/- 5.2) were statistically higher than those of Group 3(40.4 +/- 10.6, 2.8 +/- 2.5, 0.8 +/- 0.6, 6.6 +/- 5.8, 1.4 +/- 0.1, 36.5 +/- 16.5, 53.0 +/- 33.2, 2.6 +/- 2.2). The special anti-SRBC IgG response in Group 1(1.67 +/- 0.19, 1.98 +/- 0.36, 1.12 +/- 0.50, 1.38 +/- 0.30, 2.75 +/- 0.15, 2.60 +/- 0.28, 2.86 +/- 0.10, 2.50 +/- 0.20) were much stronger than those in Group 3 (0.59 +/- 0.30, 0.56 +/- 0.21, 0.21 +/- 0.16, 0.22 +/- 0.01, 0.81 +/- 0.25, 0.74 +/- 0.25, 0.69 +/- 0.26, 1.38 +/- 0.41). Furthermore, the results of DTH showed positive response and the ratios for diameter of skin rash > 5 mm at 24, 48, 72, 96 h were 16/16, 16/16, 16/16, 15/16 respectively in Group 1, while those in Group 3 were 8/15, 1/15, 1/15, 1/15 respectively. Total cell count in the BALF, LALN and spleen weight, and special IgG secreted from spleen cells in Group 1 were higher too. Group 2 expressed almost of the same but with mild immunologic responses as Group 1.</p><p><b>CONCLUSION</b>Silicosis-induced extremely strong DTH and over-response of humoral immunity to some antigens may contribute to the likelihood of silicosis complicated with tuberculosis.</p>
