RESUMO
@#Objective To investigate the perioperative efficacy and safety of all-port robotic lobectomy versus thoracoscopic lobectomy in stageⅠA non-small cell lung cancer. Methods The clinical data of patients with stageⅠA non-small cell lung cancer who underwent lobectomy with lymph node dissection performed by the same operator in our center from June 2019 to June 2022 were retrospectively analyzed. The patients were divided into a robotic group and a thoracoscopic group according to different procedures. We compared the relevant indexes such as operation time, intraoperative bleeding, number of lymph node dissection stations, number of lymph node dissection, postoperative tube time, postoperative hospitalization time, closed chest drainage volume, postoperative pain, postoperative complications and hospitalization cost between the two groups. Results There were 83 patients in the robotic group, including 34 males and 49 females with a median age of 60.0 (53.0, 67.0) years, and 94 patients in the thoracoscopic group, including 36 males and 58 females with a median age of 60.5 (54.0, 65.3) years. There was no conversion to thoractomy or death in postoperative 90 days in both groups. No statistical difference was seen in the operation time, total postoperative drainage volume and postoperative complication rates between the two groups (P>0.05). Patients in the robotic group had less intraoperative bleeding (P<0.001), more lymph node dissection stations (P=0.002) and numbers (P=0.005), less postoperative pain (P=0.002), and shorter postoperative time with tubes (P=0.031) and hospital stay (P<0.001). However, the surgery was more expensive in the robotic group (P<0.001). Conclusion All-port robotic surgery is safe and effective for patients with early-stage non-small cell lung cancer with less intraoperative bleeding, more lymph node dissection, less postoperative pain, and shorter hospital stay compared with the thoracoscopic surgery.

RESUMO
Objective@#To investigate the prevalence of anemia among students aged 6-15 years old participated in the Nutrition Improvement Program for Rural Compulsory Education Program in 2012-2021 in Hunan Province, and to explore associated factors.@*Methods@#A cluster random sampling method was used. The survey was conducted among compulsory education students who came from counties in Hunan Province where nutrition improvement plan and key surveillance were carried out. Height and weight were measured, hemoglobin, dietary habits and health knowledge were collected.@*Results@#Since the implementation of nutrition improvement plan in 2012, the anemia rate decreased from 12.8% to 9.3%, the average hemoglobin content decreased from 133.9 g/L to 130.0 g/L. The proportion of students eating meat every day increased from 20.4% to 47.3%. Students eating three or more servings of table tennis ball size of meal increased from 21.4% to 47.3%. The proportion of students eating more than three kinds of vegetables per day was 39.1% in 2016 and 32.6% in 2019, and less than 30% in other years. The proportion of students eating three or more servings of table tennis ball size of vegetables increased from 19.5% to 39.6%, and the proportion of students eating snack less than once a day increased from 13.1% to 76.9%. The proportion of students drinking beverages less than once a day increased from 36.5% to 90.7%. Girls, older than 12 years, not eating meat every day, and who eat less than 1 serving of table tennis ball size of meat, eat less than 3 servings of table tennis ball size of vegetables and fruit at one time, and who eat less than 3 kinds of vegetables every day, and those who grow slowly had higher risk of anemia. Potential factors of anemia in students varied by survey year.@*Conclusion@#The implementation of the compulsory education has improved the nutritional status of compulsory education students in rural areas of Hunan Province, but anemia still occurs. Potential factors associated with childhood anemia are changing. Child health literacy education should adapt to the changing social and economic enviornment, as well as lifestyles. Targeted and appropriate nutritional education and intervention are greatly needed.
RESUMO
Objective:To investigate the application value of dynamic scintigraphy single-photonemission computed tomography (SPECT) 99m-technetium-galactosyl human serum albumin diethy-lenetriamine pentaacetic ( 99Tc m-GSA) scintigraphy in assessing liver function of perihilar cholangio-carcinoma after portal vein embolization (PVE). Methods:The retrospective and descriptive study was conducted. The clinicopathological data of 16 patients with perihilar cholangiocarcinoma who underwent 99Tc m-GSA scintigraphy after PVE in Beijing Tsinghua Changgung Hospital Affiliated to Tsinghua University from October 2019 to January 2021 were collected. There were 8 males and 8 females, aged from 46 to 78 years, with a median age of 64 years. Observation indicators: (1) liver volume after PVE; (2) liver function after PVE; (3) typical case analysis. Measurement data with normal distribution were represented as Mean± SD. Count data were represented as absolute numbers or percentages. Comparison of data of the same patient was analyzed using the paired t test. Results:(1) Liver volume after PVE:the morphological liver volume and functional liver volume for the 16 patients were (1 420±211)mL and (389±112)mL. The morphological liver volume and functional liver volume were (636±143)mL and (234±106)mL of planning reserved lobe, (784±210)mL and (151±106)mL of planning resection lobe, respectively. The functional liver density (FLD) of planning reserved lobe and planning resection lobe were 0.36±0.12 and 0.19±0.11, showing a significant difference between them ( t=3.794, P<0.05). The planning resection rate of morpholo-gical liver volume and functional liver volume were 37.8%±0.6% and 54.8%±0.2%, showing a significant difference between them ( t=?3.720, P<0.05). (2) Liver function after PVE: 13 of 16 patients completed the indocyanine green (ICG) test, and 3 patients didn't complete the ICG test due to intolerance. For the 13 patients undergoing ICG test, the total ICG-K value was (0.15±0.03)/minutes, and the ICG-K value of planning reserved lobe was (0.07±0.02)/minutes. The total GSA-K value of 16 patients was (0.14±0.10)/minutes, and the GSA-K value of planning reserved lobe was (0.08±0.06)/minutes. (3) Typical case analysis: a 46-year-old male patient with type Bismuth Ⅲa perihilar cholangiocarcinoma was planned to perform perihilar hepatectomy combined with right hepatectomy. The imaging evaluation showed that the volume of reserved liver lobe accounted for 27% of the total liver volume. The serum total bilirubin was 256 μmol/L when admitted and decreased to 118 μmol/L on the day 5 after percutaneous transhepatic biliary drainage. The right anterior and right posterior branches of PVE was performed. SPECT 99Tc m-GSA examination was performed on the day 37 after PVE. The morphological liver volume was 559 mL of planned reserved lobe and 1 461 mL of the whole liver. The planned morphological liver volume resection rate was 61.7%. ICG-K was 0.12/minutes of the whole liver, and 0.04/minutes of planned reserved lobe. The functional liver volume was 134 mL of planned reserved lobe and 309 mL of the whole liver. The planned resection rate of functional liver volume was 56.6%. The GSA-K was 0.20/minutes of the whole liver and 0.09/minutes of planned reserved lobe. R 0 resection was achieved in perihilar hepatectomy combined with right hepatectomy and no liver failure occurred. The survival time of patients was 11 months. Conclusion:Dynamic SPECT 99Tc m-GSA scintigraphy can effectively evaluate the regional function of the reserved liver lobe in patients with perihilar cholangiocarcinoma after PVE.
RESUMO
Objective To explore the effects of compound Danshen dripping pills on the expression levels of micro RNA-1 (miR-1) and inflammatory factors in serum of patients with acute myocardial infarction (AMI) after percutaneous coronary intervention (PCI). Methods A total of 180 AMI patients admitted to Mindong Hospital of Ningde City from March 2017 to October 2018 were divided into a compound Danshen dripping pills group and a conventional western medicine treatment group, 90 cases in each group. According to the disease situations of all the patients, they needed to undergo PCI treatment, after the intervention, in the conventional western medicine treatment group, aspirin enteric-coated tablet (metformin hydrochlorid) was given as the basic anti-coagulation medicine and in the compound Danshen dripping pill group, on the basic treatment, 10 Danshenn pills each time, 3 times a day, were orally applied. Both groups were evaluated for efficacy after 2 months of continuous treatment. Echocardiography was used to detect the patients' cardiac functions; the changes of the expression levels of serum miR-1, interleukins (IL-1, IL-6), tumor necrosis factor-α (TNF-α), and myocardial troponin I (cTnI) and creatine kinase isoenzyme (CK-MB) in the two groups before and after treatment were observed. Results After treatment in both groups, the left ventricular ejection fraction (LVEF) and cardiac output index (CI) were significantly higher than those before treatment, while the expression of miR-1 and serum IL-1, IL-6, TNF-α, cTnI and CK-MB were lower than those before treatment, the LVEF and CI in the compound Danshen dripping pill treatment group were obviously higher than those in the conventional western medicine treatment group [LVEF: 0.60±0.08 vs. 0.56±0.08, CI (L·min-1·m-2): 6.02±0.34 vs. 4.91±1.50, both P < 0.05], the expression level of miR-1 and serum IL-1, IL-6, TNF-α, cTnI and CK-MB in the compound Danshen dripping pill group were lower than those in the conventional western medicine treatment group [miR-1 (2-ΔΔCt): 0.69±0.17 vs. 0.85±0.22, IL-1 (μg/L): 59.20±18.67 vs. 68.31±23.69, IL-6 (μg/L): 20.36±1.87 vs. 25.38±2.39, TNF-α (μg/L): 28.65±1.63 vs. 31.86±2.92, cTnI (μg/L):3.12±0.88 vs. 4.03±0.97, CK-MB (U/L): 29.18±10.52 vs. 34.28±10.21, all P < 0.05]. Conclusion Compound Danshen dripping pills can reduce serum the expression levels of miR-1 and inflammatory cytokines in patients with AMI after PCI.
RESUMO
Objective To investigate the expression of androgen receptor(AR),ATAD2 in hepatocellular carcinoma(HCC) and the correlations with clinicopathological features,and the role of DHT/AR and ATAD2 in proliferation of HCC cells.Methods The samples of 75 patients with HCC in the First Affiliated Hospital of China Medical University from February 2012 to December 2012 were collected.LM3 and Huh7 cells were divided into control group,DHT group,DHT + CDX (bicalutamide) group and CDX group;and also divided into Ri-ATAD2 group (adding interference fragments) and Ri-C group (adding control vector sequence).Immunohistochemistry was used to detect the expression of AR and ATAD2,and to analyze the correlations between clinical features and survival of patients.Real-time PCR and Western Blot were used to detect the expression of AR and ATAD2,and CCK-8 was used to detect cell proliferation.Results HCC patient samples were grouped according to AR and ATAD2 expression.Compared with low AR expression group (n =31),the ratio of tumor ＜5 cm in high expression group (n =44) was higher,and the ratio of TNM stage Ⅰ + Ⅱ was lower.Compared with low ATAD2 expression group (n=35),the ratio of metastasis and tumor differentiation grade Ⅲ + Ⅳ was higher in high expression group (n=40),and the difference was statistically significant (P ＜ 0.05).The overall survival rate of patients with high expression of ATAD2 was lower than other patients,and the differences were statistically significant (P＜0.05).Multivariate Cox regression analysis showed that ATAD2 expression (HR=1.935,95％ CI:1.066～3.515) and metastasis (HR=2.212,95％ CI:1.059～4.619) were independent predictors of poor prognosis.Compared with LO2 cells,the mRNA and protein level of AR and ATAD2 in LM3 and Huh7 cells were significantly higher,and the differences were statistically significant (P＜0.05).And the proliferation rate of HCC cells increased significantly after 48 and 72 hours compared with the control group,and the differences were statistically significant (P＜0.05).After adding CDX,the proliferation of LM3 and Huh7 induced by DHT was inhibited.DHT enhanced the expression of ATAD2,while CDX inhibited the expression of ATAD2.The expression of ATAD2 protein decreased when LM3 and Huh7 cells were interfered.Compared with Ri-C group,the proliferation of HCC cells in Ri-ATAD2 group decreased significantly after the DHT treatment 48 and 72 hours,and the difference was statistically significant (P＜0.05).Conclusions DHT/AR promoted the proliferation of HCC cells by inducing ATAD2 expression.Modulating ATAD2 expression may be the potential mechanism of DHT/AR in HCC proliferation.

RESUMO
To study the expression and distribution of neuropeptide Y (NPY) and long leptin receptor (OB-Rb) in the gastrointestinal tract of giant panda, samples of three animals were collected from the key laboratory for reproduction and conservation genetics of endangered wildlife of Sichuan province, China conservation and research center for the giant panda. Paraffin sections of giant panda gastrointestinal tissue samples were observed using hematoxylin-eosin staining (HE) and strept actividin-biotin complex immunohistochemical staining (IHC). The results show that the intestinal histology of three pandas was normal and no pathological changes, and there were rich single-cell and multi-cell mucous glands, long intestinal villi and thick muscularis mucosa and muscle layer. Positive cells expressing NPY and OB-Rb were widely detected in the gastrointestinal tract by IHC methods. NPY positive nerve fibers and neuronal cell were widely distributed in submucosal plexus and myenteric plexus, especially in the former. They were arranged beaded or point-like shape. NPY positive cells were observed in the shape of ellipse and polygon and mainly located in the mucous layer and intestinal glands. OB-Rb positive cells were mainly distributed in the mucous layer and the laminae propria, especially the latter. These results confirmed that NPY and OB-Rb are widely distributed in the gut of the giant panda, which provide strong reference for the research between growth and development, digestion and absorption, and immune function.

Methods From 2008 to 2012,fixed and mobile surveillance sites in potential endemic areas of 2 counties in Hubei Province were selected. The immunological assays and stool examinations were carried out to investigate the schistosome infection situation of local people, mobile population and livestock. The distribution of Oncomelania hupensis snails was investigated in risk areas and suspicious ar-eas,and spreading patterns of snails were observed in the rivers that directly connected with the Yangtze River. Results A total of 6 052 local people aged 6-65 years were screened by IHA immunological tests,and the positive rate of antibody was 1.19%(72/6 052). Totally 72 antibody positives were examined by Kato-Katz technique and there were no positives. A total of 5 004 mo-bile persons were tested by IHA immunological tests and the positive rate was 1.36%(68/5 004). Totally 68 antibody positives were examined by Kato-Katz technique and there were no positives. Totally 287.07 hm2 potential endemic areas were investigated for Oncomelania snail detection,and no snails were found. The investigation on snail spreading patterns and the surveillance on suspicious circumstances were carried out,with no snails found. Conclusions In the schistosomiasis potential endemic areas, some positives of IHA immunological tests are found. Therefore,monitoring is still needed to be strengthened.
