RESUMEN
@#Objective To compare the clinical efficacy of subxiphoid video-assisted thoracoscopic surgery (XVATS) and conventional intercostal VATS (CVATS) extended thymectomy for myasthenia gravis (MG). Methods The clinical data of MG patients who underwent extended thymectomy in the Department of Thoracic Surgery of Xuzhou Central Hospital from October 2016 to October 2021 and finished the follow-up were retrospectively reviewed. They were divided into an XVATS group and a CVATS group according to the procedure. The perioperative variables and clinical efficacy of the two groups were compared. Results A total of 84 patients were collected, including 43 males and 41 females, with a mean age of 52.3 years. There were 41 patients in the XVATS group and 43 patients in the CVATS group. There was no mortality, cardiopulmonary thrombosis, prolonged air leak, or mediastinal infection. Additionally, the CVATS group recorded 5 (11.6%) patients of conversion to open thoracotomy, 1 (2.3%) patient of postoperative MG crisis, 1 (2.3%) patient of bleeding in thorax, and 1 (2.3%) patient of chylothorax. The operation time (127.4±50.4 min vs. 122.9±38.6 min), intraoperative bleeding [46.9 (25.7, 79.2) mL vs. 45.7 (21.9, 92.1) mL], incidence of complications [0 vs. 7.0% (3/43)], chest tube duration (4.3±1.9 d vs. 4.8±2.8 d), follow-up time (19.1±8.5 months vs. 22.5±13.7 months), the proportion of residual mediastinal fat tissue [12.2% (5/41) vs. 4.7% (2/43)], and total MG remission rate [29.3% (12/41) vs. 51.2% (22/43)] were not statistically different between the two groups (P>0.05). However, the two groups showed significantly different incidence of conversion to open thoracotomy [0 vs. 11.6% (5/43), P=0.024], postoperative hospital stay time (8.2±3.3 d vs. 11.4±5.8 d, P=0.003) and total drainage volume [396.7 (173.8, 542.5) mL vs. 218.8 (102.1, 430.0) mL, P=0.038]. Conclusion XVATS extended thymectomy is technically safe and feasible; however, more evidence is warranted before the recommendation of this approach for the treatment of MG.
RESUMEN
Objective:To evaluate the change trend of smoking prevalence and the composition of main causes of death in Tianjin from 2010 to 2019.Methods:The study was based on the data collected in the Tianjin All Cause of Death Surveillance System from 2010 to 2019. A total of 699 372 cases were included in the study. The smoking prevalence, ex-smoking and never smoking prevalence were calculated according to different death years and gender. The proportion of smoking status was calculated according to the year of birth and gender. The distribution of smokers dying of smoking related diseases were calculated by different age-group. The change trend of smoking rate was analyzed by Joinpoint regression 4.9.0.0 statistical software. The diseases that smokers died of were expressed by proportion.Results:From 2010 to 2019, the smoking rate of dead residents decreased from 28.7% to 21.4%, and the average annual change percentage (AAPC) was -3.0% (95% CI: -3.9%, -2.2%). The same trend was shown in dead residents of different genders. The proportion of ex-smokers showed an upward trend, from 10.5% in 2010 to 14.7% in 2019; The proportion of light smokers increased with the postponement of birth year. The proportion of light smokers born at and before year 1950 was 14.7%, while the proportion of light smokers born at and after year 1981 was as high as 85.9%; the proportion of heavy smokers decreased with the year of birth. Lung cancer and cardiovascular and cerebrovascular diseases were the main causes of death of smokers and quitters. 13.86% of quitters died of lung cancer, which was slightly lower than that of smokers (16.39%) and significantly higher than that of non-smokers (5.55%). With the increase of smoking degree, the proportion of smokers who died of lung cancer also increased gradually, from 9.19% to 19.11%. Conclusions:From 2010 to 2019, the smoking prevalence of dead residents in Tianjin shows a downward trend, which is consistent with the change trend of the overall smoking prevalence of residents in Tianjin. Lung cancer, acute myocardial infarction and ischemic heart disease rank among the top three causes of death among smokers.
RESUMEN
Objective@#To analyze the long-term trend of mortality and years of life lost (YLL) of gastric cancer in Tianjin from 1999 to 2015.@*Methods@#From January 1, 1999 to December 31, 2015, the data of gastric cancer deaths was collected from the Tianjin death surveillance system. The inclusion criteria of death due to gastric cancer were coded by using 151 in the 9th edition of the international classification of diseases (ICD) (1999-2002) and C16 in the 10th edition of ICD (2003-2015). The crude and age-standardized mortality rate (ASR) of gastric cancer was calculated according to Segi′s world standard population. YLL was calculated according to the standard method of the disease burden of WHO. The Joinpoint regression was used to calculate the average annual percentage change (AAPC) to indicate the trend of mortality and YLL of gastric cancer.@*Results@#From 1999 to 2015, there were 20 000 deaths of gastric cancer in Tianjin. The proportion of gastric cancer death in the population aged 0-44 years old, 45-64 years old, and 65 years old and above was 4.9%, 30.4%, and 64.8%, respectively. The proportion of males and urban was 67.1% and 67.5%, respectively. From 1999 to 2015, the crude mortality rate was from 12.10/100 000 to 12.58/100 000. The ASR was from 11.04/100 000 to 7.24/100 000. The average annual YLL number was 29 625.83 person-years and the rate was 3.09 person-years per thousand people. From 1999 to 2015, the crude mortality rate and the PYLL of gastric cancer in Tianjin were stable (the AAPC was 0.34% and -0.24%, all P values >0.05). The ASR showed a downward trend (AAPC=-2.58%, P<0.001).@*Conclusion@#From 1999 to 2015, the ASR of gastric cancer in Tianjin showed a downward trend, and the YLL of gastric cancer was stable.

Objective To approach Professor Zhu Guangli's regular pattern of differentiation of symptoms and signs in patients with hypertension accompanied by complications and in accord with the individual manifestations to add or subtract the ingredients in the prescription.Methods The patients with essential hypertension selected were those who the first time came to the Affiliated Guangxing Hospital of Zhejiang Chinese Medical University or Hangzhou Hospital of Traditional Chinese Medicine (TCM) of Zhejiang Province from September 2012 to January 2015, and were continuously followed up in the hospitals having their clinical data comprehensive. The complications, combination diseases and symptoms of hypertension were conducted as dependent variables, while the applied Chinese medicines were acted as independent variables. QUEST algorithms were employed to analyze the different dependent variables to evaluate the importance contribution rate (ICR) of every kind of Chinese medicine.Results There were 9 types of complications or combination diseases [including hyperlipemia, coronary heart disease, cardiac arrhythmia, hyperglycemia, trace albuminuria, lacunar cerebral infarction, elevation of creatinine in blood (azotemia), liver dysfunction and cardiac dysfunction] and 39 types of symptoms obtained (including dizziness, palpitation, chest oppression, insomnia, lack of strength, soreness of the waist and knees, dry mouth, loose stool, fatigue, apontaneous sweating, headache, shortness of breath, coprostasis, fullness in the stomach, blurred vision, limb numbness, low spirit, chest pain, poor appetite, abdominal distension, excessive dreaming, tinnitus, flush of the face, neck rigidity, hectic fever, bitterness in the mouth, cough, ructus, nocturia, fremitus, stenagma, pharyngalgia, heaviness in head, nocturnal sweating, frequent urination, coughing of sputum, chillness and cold limbs, aphthous stomatitis and sialosis) being the QUEST decision models. All kinds of the TCM employed in all the patients paying visits for 755 times were summed up, and the individual drug frequency of presentation in the prescription was recorded. In the study, 171 sorts of TCM and 10 620 of cumulative frequency (freq.) were involved in 755 prescriptions. The average sorts of TCM was 14.07±1.53 per prescription. The top ten kinds of TCM the most commonly used (freq.) were as follows: tuckahoe (588), Chinese yam (551), wolfberry fruit (496), white peony root (442), abalone shell (405), gastrodia tuber (395), lilyturf root (325), Huai wheat (293), curcuma root (281), rush pith (277), accounting for 38.16% in the total frequency. There were 33 kinds of TCM with frequency > 100, accounting for 74.65% in the total frequency. By the analyses of QUEST algorithms directing to the complications and combination diseases to add or subtract the items of TCM, it was discovered that the drugs with ICR > 5% were as follows: in lacunar cerebral infarction, the drug application frequencies or ICRs of batryticated silkworm and bitter cardamom were 32.69% and 50.74% respectively; in coronary heart disease, the ICRs of pseudostellaria root, astragalus root, white sandal wood and lepidium seed were 23.05%, 17.70%, 15.31% and 5.06% respectively; in cardiac arrhythmia, the ICRs of astragalus root, flavescent sophora root, Huai wheat and dragon tooth and dragon bone were 46.65%, 11.56%, 7.56%, 7.13% and 6.28% respectively; in cardiac dysfunction, the ICRs of lepidium seed and white hyaciath bean were 92.97% and 7.03%; in hyperlipemia, the ICRs of cassia seed, white sandal wood, dried rehmannia root and sargentgloryvine stem were 24.26%, 12.47%, 10.51% and 5.81% respectively; in hyperglycemia, the ICRs of trichosanthes root and dried hawthorn fruit were 51.02% and 30.18%; in trace albuminuria, the ICR of snow in June herb was 83.33%; in elevation of creatinine in blood, the ICRs of Chinese actinidia root, herb of snow in June, glossy privet fruit and centella were 81.37%, 6.21%, 6.21% and 6.21% respectively; in liver dysfunction, the ICRs of coral ardisia root, purse grass and herb of stringy stonecrop were 86.37%, 6.82% and 6.82% respectively. When the symptoms were used as the dependent variables, for the top 3 commonly seen symptoms, in the prescription, the items of TCM used with ICR > 5% were as follows: in cases with elevation of blood pressure, parasitic loranthus (ICR 89.59%) was used; with dizziness, gastrodia tuber (ICR 46.96%) and/or abalone shell (ICR 33.61%) were added; headache, rhizome of Chinese ligusticum and/or rhizome of Sichuan lovage and/or large gentian with ICR at 85.77%, 7.11% and 7.11% respectively. Conclusion Professor Zhu's essential thought in differentiation of disease and expectant treatment of hypertension in accord with the individual manifestations to add and subtract drugs in TCM is under the guidance of TCM principle of differentiation of symptoms and signs for treatment, and based on the classical theories in TCM, the reliable drugs whose actions are demonstrated clinically and experimentally are preferentially selected.

Objective To investigate the value of CARE Dose 4D technique in decreasing radiation dose and improving image quality of multi-slice spiral CT in adult chest scanning.Methods 100patients of chest CT scanning were equally divided into study group and control group randomly.CARE Dose 4D Technique was used in study group.Effective mAs value,volume CT dose index (CTDIvol) and dose length product (DLP) were displayed automatically in machine while chest scanning; those values and actual mAs value of every image were recorded respectively.The image quality at apex of lung,lower edge of aorta arch,middle area of left atrium and base of lung on every image of 400 images was judged and classified as three level (excellent,good,poor) by two deputy chief physicians with double blind method,the image noise at corresponding parts was measured.Results While setting 80 mAs for quality reference mAs,the effective mAs value in study group most decreased 44 mAs than control group with an average decrease of 9.60( 12.0% ) ,CTDIvol with 4.75 mGy with an average decrease of 0.95 mC y( 11.0% ) ,DLP 99.50% in study group,with 98.0% in control group.But it was higher at apex of lung and base of lung,lower at middle area of left atrium,and similar at lower edge of aorta arch in study group than contrast group.The image noise were lower at apex of lung and base of lung in study group than control group (t =6.299 and 2.332,all P ＜ 0.05 ) ,higher at middle area of left atrium in study group than control group (t=3.078,P ＜0.05) and similar at lower edge of aorta arch in study group than control group (t =1.191,P ＞0.05).Conclusions CARE Dose 4D technique provides a function regulated mAs real-time on line,it not only raises utilization rate of radiation and decreases radiation dose,but also promises and increases image quality in chest CT scanning,and has some clinical significance.
RESUMEN
Objective To describe the current status of adult overweight and obesity in urban and suburb areas of Tianjin.Methods 2 283 adult people including 1 131 from urban and 1 152 from suburb were selected by multi-stage cluster random sampling.The waist circumference,weight and height of the subjects were measured.Then the BMI was calculated.Results The mean BMI of adult people in Tianjin was 25.05?5.02 kg/m2,the overweight rate was 36.9%,the obesity rate was 20.0% and the abdominal obesity rate was 63.9%.The prevalent rates of overweight,obesity and abdominal obesity in different age groups showed significant differences.The rates of overweight,obesity and abdominal obesity increased with ages in urban area.The overweight rate in 40～49 yrs and the obesity rate in 50～59 yrs reached their peak values in suburb.Besides the overweight rate in urban was significantly higher,the obesity rate and abdominal obesity rate were no significant differences between urban and suburb.The prevalent rates of overweight,obesity and abdominal obesity showed no significant differences between the adult male and female in Tianjin,but the prevalent rates of obesity and abdominal obesity in female were significantly higher than those in male in the suburb.The prevalence of obesity in the middle-ages showed significant differences between different occupational population,the retired taking the highest while the workers taking the lowest value.The prevalence of obesity showed no significant differences between population with different education background and different income situation.Conclusion The rates of adult overweight and obesity in Tianjin were higher than those of all over the country in 2002,and the abdomen obesity reached to 63.9%.Intervention should be taken to change this situation as soon as possible.
RESUMEN
Objective To investigate the cerebral CT appearances of toxic encephalopathy of tetramine and improve the recognition on this disease. Methods Four cases of toxic encephalopathy of tetramine were collected and their cerebral CT appearances were retrospectively analyzed. Results Cerebral CT appearances in acute phase (within 8 days): (1) cerebral edema in different degree. CT abnormalities consisted of cortical hypodensities and complete loss of gray-white matter differentiation. The CT value were in 11-13 HU, and to be watery density in serious case,(2)subarachnoid hemorrhage. It demonstrated the signs of poisoning hypoxic ischemic encephalopathy in chronic phase. Conclusion The cerebral CT appearances of toxic encephalopathy of tetramine had some character in acute phase and it can predict the serious degree of intoxication, but there was no characteristic findings in chronic phase.
