Objective By detecting microsatellite instability(MSI) and loss of heterozygosity(LOH) in FHIT gene in sputum specimen,we intended to evaluate the sensitivity of FHIT gene detection to early diagnosis of lung cancer and explore effective method to screen lung cancer.Methods Based on liquid-based cytology,we collected and isolated sputum specimens in high risk group,abstracted DNA,and detected MSI and LOH in FHIT gene.Results The positive rate of MSI or LOH at single locus was between 41.6% and 49.5%;the site D3S1300 was the highest and it was 49.5%.At least 1 site out of 3 sites that had abnormal microsatellite accounted for 72.3% in lung cancer patients,two sites that appeared to change accounted for 45.5%,which was significantly different compared to non-lung cancer patients(P

Objective To observe the changes of serum C reactive protein (CRP) and blood glucose in patients with non small cell lung cancer after video-assisted thoracoscopic surgery.Methods 96 patients with non small cell lung cancer were selected,and they were randomly divided into the observation group (48 cases) and the control group(48 cases) according to the digital table.The observation group received thoracoscopic surgery,while the control group received traditional thoracotomy.The changes of serum CRP and fasting blood glucose were compared between the two groups before and after operation,at 24h,36h and 72h after operation.Results The operation time of the observation group [(198.3 ± 36.4) min] was longer than that of the control group [(136.5 ± 30.8) min] (t =3.014,P ＜0.05).There was no significant difference in the number of lymph node dissection between the two groups [(13.4 ± 2.8) vs.(14.1 ± 2.6)] (t =1.082,P ＞ 0.05).The amount of intraoperative bleeding,drainage time,postoperative drainage volume,postoperative pain score in the observation group were (149.2 ± 44.7)mL,(6.1 ± 2.5) d,(781.6 ± 59.6) mL,(5.2 ± 1.6) points respectively,which in the control group were (261.5 ± 57.2) mL,(8.6 ± 2.9) d,(1103.6 ± 87.3) mL,(8.5 ± 2.0) points respectively,the differences were statistically significant between the two groups (t =7.152,2.741,6.034,2.925,all P ＜ 0.05).The incidence rate of postoperative complications in the observation group was 4.2％,which was significantly lower than 10.4％ in the control group (x2 =8.960,P ＜ 0.05).There was no significant difference in serum CRP between the two groups (t =0.5612,P ＞ 0.05).The postoperative serum CRP was significantly increased,and CRP levels of postoperative 24h,36h,72h in the observation group [(81.26 ± 10.24) mg/L,(49.64 ± 9.17) mg/L,(27.53 ± 5.38) mg/L] were lower than those of the control group [(98.46 ± 11.28) mg/L,(60.73 ± 9.82) mg/L,(39.78 ± 6.14) mg/L] (t =4.921,4.068,3.724,all P ＜ 0.05).There was no statistically significant difference in preoperative blood glucose between the two groups(t =0.3942,P ＞ 0.05).The postoperative blood glucose was significantly increased,and blood glucose levels of postoperative 24h,36h,72h in the observation group[(9.75 ± 1.91) mmol/L,(7.64 ± 1.06) mmol/L,(6.39 ± 0.72) mmo]/L] were lower than those of the control group [(13.25 ± 2.06) mmol/L [(9.77 ± 1.53) mmol/L [(8.03 ± 0.69) mmol/L](t =8.912,4.601,3.005,all P ＜ 0.05).Conclusion Thoracoscopic surgery for non-small cell lung cancer has less impact on CRP and blood glucose,it may be more favorable for patients prognosis.

Objective:To evaluate the changes of quality of life in patients with axial spondyloarthritis (ax-SpA) after treatment with non-steroidal anti-inflammatory drugs (NSAIDs) by the 36-item Short Form Health Survey (SF-36).Methods: 120 patients diagnosed with ax-SpA were collected in the first Affiliated Hospital of Zhengzhou University from October 2014 to September 2015.They all agreed to be treated with the special drugs and assessed by special scale.Then they all signed the agreement.In the 3 months,double-blind,parallel controlled trial patients were randomized to 200 mg twice daily (bid) imrecoxib,or 200 mg twice daily (bid) celecoxib.They were assessed for the changes of quality of life at enrollment and after three months of NSAIDs therapy by the SF-36 of Chinese edition.The correlation between quality of life and erythrocyte sedimentation rate (ESR),C-reactive protein (CRP),Bath Ankylosing Spondylitis Disease Activity Index (BASDAI),Bath Ankylosing Spondylitis Functional Index (BASFI),Spondylo Arthritis Research Consortium of Canada (SPARCC) was analyzed.Results: A total of 116 ax-SpA patients completed the study and 4 patients were lost to follow-up.We used the SF-36 scale to assess the quality of life in patients with ax-SpA before and after 3 months,NSAIDs treatment.The treatment effects were not statistically significant difference between the two drugs (P>0.05).After all the patients were treated with NSAIDs for 3 months,there was statistically significant difference (P<0.05) of the physical functioning,role-physical,bodily pain,general health,social functioning,role-emotional;and there was no statistically significant difference (P>0.05) of vitality and mental health.The positively significant correlations had been identified between BASDAI and PF,RP,BP,GH,VT,SF,RE (P<0.05),while no significant correlation was found between BASDAI and MH (P>0.05).A positively significant correlation had been identified between BASFI and PF,RP,BP,GH,SF,RE,MH (P<0.05),while no significant correlation was found between BASFI and VT (P>0.05).The ESR was positively correlated with SF,RE (P<0.05);and CRP was positively correlated with SF,MH (P<0.05);and SPARCC was positively correlated with PF (P<0.05).BASDAI and BASFI were the important influence factors of PF (P<0.05);and BASDAI was the important influence factor of BP,GH,VT,RE(P<0.05);BASFI was the important influence factor of RP,SF,MH(P<0.05).Conclusion: Non-steroidal anti-inflammatory drugs can improve the quality of life of the ax-SpA patients.Imrecoxib and celecoxib have the equivalent curative effect.SF36 scale is suitable for the assessment of the quality of life in patients with ax-SpA.

Objective:To investigate the influencing factors for the number of lymph node harvested after Da Vinci robotic and laparoscopic radical gastrectomy for gastric cancer.Methods:The retrospective case-control study was conducted. The clinicopathological data of 1 396 patients who underwent Da Vinci robotic or laparoscopic radical gastrectomy for gastric cancer in the First Affiliated Hospital of Nanchang University from December 2014 to July 2019 were collected. There were 991 males and 405 females, aged (60±11) years. Surgery using Da Vinci robotic system or laparoscopic system was completed according to patients' wishes. Cases with early gastric cancer underwent D 1+ lymphadenectomy and cases with advanced gastric cancer underwent standard D 2 lymphadenectomy. Observation indicators: (1) intraoperative situations; (2) postoperative situations; (3) influencing factors for the number of lymph node harvested after radical gastrectomy for gastric cancer; (4) follow-up and survival. Follow-up using outpatient examination or telephone interview was performed to detect survival of patients up to October 2020. Measurement data with normal distribution were represented as Mean± SD. Univariate analysis was done using the chi-square test or Fisher exact probability. Multivariate analysis was performed using Logistic regression model. The survival rate was calculated by Kaplan-Meier method. Results:(1) Intraoperative situations: all the 1 396 patients underwent radical gastrectomy, including 415 cases undergoing Da Vinci robotic radical gastrectomy and 981 cases undergoing laparoscopic radical gastrectomy. Thirty-five of the 1 396 patients were converted to open surgery, including 5 cases undergoing Da Vinci robotic radical gastrectomy and 30 cases undergoing laparoscopic radical gastrectomy. Of the 1 396 patients, 983 cases underwent distal gastrectomy, 400 cases underwent total gastrectomy and 13 cases underwent proximal gastrectomy, among which 597 cases underwent Billroth Ⅰ anastomosis, 385 cases underwent Billroth Ⅱ anastomosis, 401 cases underwent Roux-en-Y anastomosis and 13 cases underwent residual stomach-esophagus anastomosis. The operation time, volume of intraoperative blood loss and cases with intraoperative blood transfusion were (221±51)minutes, (201±81)mL, 24 of 415 cases undergoing Da Vinci robotic radical gastrectomy, and (196±42)minutes, (232±76)mL, 75 of 981 cases undergoing laparoscopic radical gastrectomy, respectively. (2) Postoperative situations: the time to postoperative first flatus, time to postoperative initial liquid food intake and duration of postoperative hospital stay of the 1 396 patients were (3.0±1.0) days, (4.2±1.5) days and (9.0±3.8) days, respectively. Two hundred and ten of the 1 396 patients had postoperative complications including 170 cases with grade Ⅰ-Ⅱ complications and 40 cases with grade Ⅲ-Ⅴ complications. Eight of the 210 patients with postoperative complications died of serious complica-tions and the other 202 cases were cured after symptomatic treatment. Results of postoperative histopathological examination showed that there were 958 cases of adenocarcinoma, 220 cases of mucinous adenocarcinoma, and 218 cases of signet ring cell carcinoma. The number of lymph node harvested and the number of positive lymph node of the 1 396 patients were 26.0±8.3 and 3.6±0.9, respectively, and cases with the number of lymph node harvested ≥16 or <16 were 1 312 and 84. (3) Influencing factors for the number of lymph node harvested after radical gastrectomy for gastric cancer: results of univariate analysis showed that the operating surgeon, operation method, range of gastric resection, nerve invasion, degree of tumor invasion and tumor pathological N stage were related factors influencing the number of lymph node harvested after Da Vinci robotic and laparoscopic radical gastrectomy for gastric cancer ( χ2=13.167, 6.029, 15.686, 5.573, 9.402, 17.139, P<0.05). Results of multivariate analysis showed that the operating surgeon, operation method, range of gastric resection and tumor pathological N stage were independent factors influencing the number of lymph node harvested after Da Vinci robotic and laparoscopic radical gastrectomy for gastric cancer ( odds ratio=1.589, 2.018, 1.787, 0.267, 95% confidence interval as 1.221?2.068, 1.140?3.570, 1.066?2.994, 0.103?0.689, P<0.05). (4) Follow-up and survival: of the 1 396 patients, 1 256 cases were followed up for 2 to 70 months, with a median follow-up time of 27 months. The 3-year cumulative survival rate of the 1 256 cases was 70.2%. Conclusion:The operating surgeon, operation method, range of gastric resection and tumor pathological N stage are independent factors influencing the number of lymph node harvested after Da Vinci robotic and laparoscopic radical gastrectomy for gastric cancer.

Objective:To preliminarily analyze the relationship between peripheral blood CD19 +CD27 +B cells, CD4 -CD8 -double-negative T cells, related cytokines and recurrence in patients with neuromyelitis optica spectrum disorders (NMOSD). Methods:A retrospective analysis was performed on the clinical data of 72 patients with NMOSD admitted to Henan Provincial People′s Hospital between January 2019 and January 2021. According to presence or absence of recurrence within 1 year after treatment, they were divided into non-recurrence group ( n=30) and recurrence group ( n=42). The data such as gender, age and score of Extended Disability Status Scale (EDSS) at admission were collected. The levels of serum triglyceride (TG), total cholesterol (CHO), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), apolipoprotein A (ApoA) 1 and apolipoprotein B (ApoB) were detected by full-automatic biochemical analyzer. The level of total protein in cerebrospinal fluid was detected by full-automatic programmed protein analyzer. The levels of immunoglobulin (Ig) G and IgM in cerebrospinal fluid were detected by immunoturbidimetry. The counts of peripheral blood CD19 +CD27 +B cells and CD4 -CD8 -double-negative T cells were detected by flow cytometry. The levels of serum interleukin (IL)-6, IL-10 and IL-2 were detected by enzyme-linked immunosorbent assay. Results:EDSS score, neutrophils, proportions of cases with positive aquaporin 4 (AQP4) antibody and autoimmune antibody in the recurrence group were significantly higher than those in the non-recurrence group (all P<0.05). There was no statistically significant difference in serum TG, HDL-C, LDH-C, ApoB, ApoA1, total protein in cerebrospinal fluid, IgG or IgM between the non-recurrence group and the recurrence group (all P>0.05). The proportions of CD19 +B cells, CD19 +CD27 +B cells and CD4 -CD8 -double-negative T cells in the recurrence group were (1.21±0.12)%, (1.61±0.17)% and (1.39±0.25)%, significantly higher than those in the non-recurrence group [(0.85±0.07)%, (1.25±0.12)%, (0.89±0.22)%, t=15.51, 3.89, 12.06, all P<0.05]. The counts of CD19 +B cells, CD19 +CD27 +B cells and CD4 -CD8 -double-negative T cells in the recurrence group were (289.50±17.64) ×10 6/L, (4.67±0.03) ×10 6/L and (64.78±6.53) ×10 6/L, significantly higher than those in the non-recurrence group [(254.56±15.34) ×10 6/L, (3.18±0.03) ×10 6/L, (47.82±4.83) ×10 6/L, t=14.27, 4.26, 12.06, all P<0.05]. The level of serum IL-10 in the recurrence group was lower than that in the non-recurrence group [(18.56±1.97) ng/ml vs (24.72±2.52) ng/ml, t=11.64, P<0.05], while levels of IL-6 and IL-2 were significantly higher than those in the non-recurrence group [(15.12±1.54) pg/ml vs (11.47±1.23) pg/ml, (28.34±2.94) pg/ml vs (22.57±2.36) pg/ml, t=10.75, 8.89, both P<0.05]. Conclusion:The levels of peripheral blood CD19 +CD27 +B cells, CD4 -CD8 -double-negative T cells and related cytokines are abnormal in NMOSD patients, which may be related to the recurrence of NMOSD.

Objective To investigate the clinical efficacy of Da Vinci robotic and laparoscopic distal gastrectomy for gastric cancer.Methods The propensity score matching and retrospective cohort study was conducted.The clinicopathological data of 171 patients with gastric cancer who were admitted to the First Affiliated Hospital of Nanchang University from January 2015 to October 2016 were collected.There were 110 males and 61 females,aged from 38 to 81 years,with a median age of 57 years.Of 171 patients,70 undergoing Da Vinci robotic distal gastrectomy for gastric cancer and 101 undergoing laparoscopic distal gastrectomy were allocated into the robotic group and laparoscopic group,respectively.Observation indicators:(1) the propensity score matching conditions and comparison of general data between the two groups after the propensity score matching;(2) intraoperative and postoperative situations;(3) situations of pathological examination;(4) follow-up.Patients were followed up by outpatient examination and telephone interview to detect severe complications and survival after discharge up to October 2018.The overall survival time was from the operation data to end of follow-up or time of death.The propensity score matching was used to perform 1 ∶ 1 matching by Empower Stats.Measurement data with normal distribution were represented as Mean ± SD,and comparison between groups was done using the t test.Measurement data with skewed distribution were represented as M (range),and comparison between groups was done using the Mann-Whitney U test.Count data were represented as absolute number,and comparison between groups was analyzed using the chi-square test and comparison of ordinal data between groups was analyzed using the Mann-Whitney U test.The survival rate and curve were respectively calculated and drawn by the Kaplan-Meier method,and Log-rank test was used for survival analysis.Results (1) The propensity score matching conditions and comparison of general data between the two groups after the propensity score matching:124 of 171 patients had successful matching,including 62 in each group.The body mass index (BMI) and tumor diameter before matching were (24.2±2.4)kg/m2 and (50±13)mm in the robotic group,(25.1±2.1) kg/m2 and (45±14) mm in the laparoscopic group,showing statistically significant differences between the two groups (t =-2.676,2.045,P＜ 0.05).The BMI and tumor diameter after matching were (24.5 ± 2.3) kg/m2 and (49 ± 14) mm in the robotic group,(24.4 ± 2.2) kg/m2 and (48 ± 12) mm in the laparoscopic group,showing no statistically significant difference between the two groups (t=0.110,0.524,P＞0.05).(2) Intraoperative and postoperative situations:the total operation time,volume of intraoperative blood loss,level of C-reactive protein at day 1 postoperatively,level of C-reactive protein at day 3 postoperatively,volume of totally abdominal drainage were (147±13) minutes,(115±12)mL,(52.2±7.2)mg/L,(33.7±11.9)mg/L,353.5 mL (range,267.0-1 350.0 mL) in the robotic group,and (140± 12) minutes,(131 ± 12) mL,(58.2±7.4) mg/L,(41.1 ± 16.9) rag/L,397.0 mL (range,255.0-1 600.0 mL) in the laparoscopic group,respectively,showing statistically significant differences in the above indexes between the two groups (t =3.163,-7.814,-4.631,-2.840,Z =-4.351,P＜0.05).(3) Situations of pathological examination:patients after matching in the two groups received R0 resection,with negative duodenal margin and gastric margin.The number of lymph nodes dissected in the robotic group and laparoscopic group were 22±4 and 20±4,respectively,with a statistically significant difference between the two groups (t=2.812,P＜0.05).(4) Follow-up:124 patients after propensity score matching were followed up for 6-37 months,with a median time of 25 months.During the follow-up,no severe surgery-related complications such as obstruction of input or output loop and dumping syndrome were found in the two groups within 3 months after operation.The 2-year overall survival rate was 82.1％ and 75.2％ in the robotic and laparoscopic group,with no statistically significant difference between the two groups (x2 =0.436,P＞0.05).Conclusions Compared with laparoscopic surgery,Da Vinci robotic distal gastrectomy for gastric cancer has advantages in postoperative recovery and minimally invasion.There are similar 2-year overall survival rates in the two groups.

Objective:To investigate the application value of white noise therapy on the alleviation of procedural pain of colostomy newborns.Methods:By a prospective, randomized and controlled trial, a total of 88 colostomy newborns in Hunan Children′s Hospital from January 2018 to January 2020 divided into experimental group (44 cases) and control group (44 cases) according to the random number table method. The control group received routine nursing; based on thesis, the experimental group played white noise intervention therapy on the basis of routine nursing. The intervention effect was assessed byNeonatal Infant Acute Pain Assessment Scale (NIAPAS), the first crying time and the duration of first crying, the first painful face and the duration of first painful face as well as heart rate and blood oxygen saturation.Results:The first crying time and the duration of first crying, the first painful face and the duration of first painful face were (28.05 ± 7.39) s, (46.18 ± 13.29) s, (32.89 ± 6.79) s, (52.75 ± 10.71) s in the experimental group, significantly shorter than in the control group (35.79 ± 5.81) s, (35.79 ± 5.81) s, (38.64 ± 10.53) s, (59.79 ± 13.52) s, the difference was statistically significant ( t values were 2.71-5.47, all P<0.05). During and after the procedure, the scores of NIAPAS were (6.32 ± 1.62) points, (4.18 ± 1.06) points in the experimental group, significantly lower than that in the control group (7.43 ± 1.78) points, (4.79 ± 1.34) points ( t=3.06, 2.38, both P<0.05); the heart rate were (152.82 ± 13.25) times/min and (147.84 ± 12.37) times/min in the experimental group, significantly lower than in the control group (166.11 ± 13.79) times/min and (155.77 ± 12.84) times/min ( t=4.61, 2.95, both P<0.05); the blood oxygen saturation were 0.979 8 ± 0.009 5 and 0.980 9 ± 0.012 4 in the experimental group, significantly higher than in the control group 0.969 1 ± 0.014 9, 0.972 3 ± 0.017 8, the difference was statistically significant ( t=4.01, 2.65, both P<0.05). Conclusions:White noise therapy can effectively alleviate procedural pain and stabilizing vital signs of colostomy newborns.

Objective:To explore the clinical characteristics, diagnosis, treatment, and follow-up of multisystem inflammatory syndrome in children (MIS-C) related to SARS-CoV-2 Omicron variant infection.Methods:A retrospective analysis was conducted on clinical data of 11 children with MIS-C, who were admitted to the Department of Pediatrics of Peking University First Hospital from December 2022 to January 2023. Clinical characteristics, treatment, and follow-up of MIS-C were summarized in this study.Results:The 11 cases contained 7 boys and 4 girls, with an age of 4.4 (2.0, 5.5) years on admission. All the patients had fever, with a duration of 7(5, 9) days. Other clinical manifestations included rash in 7 cases, conjunctival hyperemia in 5 cases, red lips and raspberry tongue in 3 cases, lymphadenopathy in 3 cases, and swollen fingers and toes in 2 cases. There were 8 cases of digestive symptoms, 8 cases of respiratory symptoms, and 3 cases of nervous system symptoms. Eight patients had multi-system injuries, and one of them had shock presentation. All 11 patients were infected with SARS-CoV-2 Omicron BF.7 variant. The laboratory examination results showed that all cases had elevated inflammatory indicators, abnormal coagulation function and myocardial damage. Six patients had elevated white blood cell counts, 5 cases had liver function abnormalities, 3 cases had kidney function abnormalities, and 8 cases had coronary artery involvement. All 11 patients received anti-infection treatment, of which 3 cases received only 2 g/kg intravenous immunoglobulin (IVIG), while the remaining 8 cases received a combination of IVIG and 2 mg/(kg·d) methylprednisolone. Among the 8 cases with coronary artery disease, 6 cases received low molecular weight heparin anticoagulation therapy. All patients were followed up in 2 weeks after being discharged, and their inflammatory markers had returned to normal by that time. The 8 cases with coronary artery disease and 3 cases with pneumonia showed significant improvement or back to normal at the 4-week follow-up. All patients had no new complications or comorbidities during follow-up of more than 3 months.Conclusions:MIS-C may present with Kawasaki disease-like symptoms, with or without gastrointestinal, neurological, or respiratory symptoms. Elevated inflammatory markers, abnormal coagulation function, and cardiac injury contribute to the diagnosis of MIS-C. IVIG and methylprednisolone were the primary treatments for MIS-C, and a favorable short-term prognosis was observed during a follow-up period of more than 3 months.

Objective: To analyze the clinical phenotype and genomic abnormality of an adult featuring congenital heart defect and multiple developmental disorders. Methods: The patient was subjected to conventional G-banding chromosomal karyotyping and single nucleotide polymorphism microarray (SNP-array) analysis. Results: The patient showed a normal karyotype, while SNP-array revealed a 42.7 Mb mosaic uniparental disomy (UPD) in the 11p15.5p12 region ([hg19] chr11: 491 333 - 43 189 376). Conclusion The mosaicism of UPD of 11p15.5p12 region probably underlies the congenital heart defect and developmental disorders in the patient.

Objective To investigate the geographical distribution and seasonal fluctuations of visceral leishmaniasis vectors sandflies in Henan Province in 2023, so as to provide insights into the prevention and control of visceral leishmaniasis vectors. Methods A total of 23 counties (districts) were sampled from 18 cities of Henan Province from May to September, 2023 as sandfly surveillance sites, and sandflies were captured using human capture and light trapping methods. Following morphological identification, the changes in the sandfly density were calculated at different months and in different breeding habitats. Results A total of 406 light traps were set at sandfly surveillance sites in Henan Province from May to September, 2023, and a total of 3 137 female sandlies were captured, with an average density of 7.73 sandlies/(light·night). A total of 1 494 Phlebotomus chinensis sandflies were captured, including 1 222 female sandflies, with an average density of 3.01 sandflies/(light·night), and the highest density of P. chinensis was found in Gongyi City [17.00 sandflies/(light·night)]. A total of 5 544 sandflies were captured using the human capture method, including 230 P. chinensis, and the density of P. chinensis appeared a unimodal distribution, with a peak in early July [5.81 sandflies/(light·night)]. Among different breeding habitats, the highest P. chinensis density was detected in pigpens [4.50 sandflies/(light·night)]. Conclusions P. chinensis was predominantly distributed in hilly areas of northern and central-western Henan Province in 2023, and the sandfly density appeared a unimodal distribution. Intensified monitoring of visceral leishmaniasis vectors is recommended.
