Abstract
Objective: To understand the epidemiological characteristics of imported COVID-19 cases in Tianjin, and provide references for risk assessment and control of imported COVID-19 cases. Methods: The information of imported COVID-19 cases were obtained from National Notifiable Disease Report System of China CDC. The data of imported COVID-19 cases reported from Tianjin airport and epidemiological surveys by CDCs at all levels from March 15, 2020 to August 31, 2021 were collected and analyzed by using software Excel 2010, SPSS 25.0 and R. Results: From March 15, 2020 to August 31, 2021, a total of 606 imported cases of COVID-19 were reported in Tianjin, in which 552 cases were finally included in the analysis. The male to female ratio of the cases was 1.8∶1, the age of the cases ranged from 3 to 77 years, and the cases were mainly reported in age group 20-39 years (59.8%). The areas where the imported case sojourned within 14 days included Europe (242 cases, 43.8%), Africa (139 cases, 25.2%), Americas (85 cases, 15.4%) and Asia (86 cases, 15.6%). The proportion of confirmed cases in autumn and winter was relatively high. During the study period, the proportion of infected persons found in custom entry quarantine decreased, and the proportion of persons with personal health declaration and under medical isolation observation increased. The interval between entry and diagnosis of infected persons tended to increase. Conclusion: The proportion of imported COVID-19 cases detected on the first day of entry at Tianjin airport decreased, and the interval to detect the infected persons trended to increase, to which close attention must be paid.

Abstract
Diabetes‐related lower extremity amputations are an enormous burden on global health care and social resources because of the rapid worldwide growth of the diabetic population. This research aimed to determine risk factors that predict major amputation and analyse the time interval from first hospitalisation to amputation by using standard management protocols and Kaplan–Meier survival curves. Data from 246 patients with diabetes mellitus and diabetic foot ulcers from the Division of Plastic and Reconstructive Surgery of the Department of Surgery at XXX Hospital between January 2016 and May 2020 were analysed. Univariate and multivariate analyses of 44 potential risk factors, including invasive ulcer depth and C‐reactive protein levels, showed statistically significant differences for those at increased risk for major amputation. The median time from hospitalisation to lower extremity amputation was approximately 35 days. Most patients with abnormal C‐reactive protein levels and approximately 70% of patients with ulcers invading the bone were at risk for lower extremity amputations within 35 days. Therefore, invasive ulcer depth and C‐reactive protein levels are significant risk factors. Other potential risk factors for major amputation and the time intervals from first hospitalisation to amputation should be analysed to establish further prediction strategies.

Abstract
Objective: Select the appropriate disease assessment indicators, formulate the comprehensive evaluation group of pneumoconiosis patients, and explore the role of the comprehensive evaluation grouping in the clinical evaluation of pneumoconiosis, and provide the basis for the prognosis of pneumoconiosis. Methods: Combined with clinical symptoms, pulmonary function, pneumoconiosis stage, acute exacerbation and complications, a comprehensive assessment of pneumoconiosis patients was established.138 newly diagnosed pneumoconiosis patients were divided into low risk group, middle risk group and (very) high risk group. The patients were followed up by telephone to record their health status and quality of life within one year after discharge from hospital. Analysis of the relationship between the comprehensive assessment group of patients with pneumoconiosis and symptom score, pulmonary function, pneumoconiosis stage, acute exacerbation and complications. The relationship between the comprehensive assessment group of pneumoconiosis patients and the risk events (the number of visits, hospitalization, mechanical ventilation, death cases in one year) and CAT score were analyzed. Results: There were significant differences in clinical symptoms, pulmonary function injury, pneumoconiosis stage, acute exacerbation and complications among patients in low risk group, middle risk group and (very) high risk group (P<0.01) . With the increase of comprehensive assessment score, CAT score increased, the risk events increased, the difference was statistically significant (P<0.01) . Spearman correlation analysis showed that the comprehensive assessment group was significantly correlated with the number of visits, hospitalization, mechanical ventilation, deaths and CAT score in one year. Conclusion: Combined with clinical symptom assessment, pulmonary function assessment, chest imaging assessment, acute exacerbation assessment, and complication assessment, the pneumoconiosis patients' comprehensive assessment group formulated can evaluate the severity of pneumoconiosis patients, and make a more accurate and comprehensive judgement of the disease.

Abstract
Objective: To investigate the effects of fluoride exposure on the thyroid hormone level and intelligence in rats and to investigate the biomarkers of intellectual impairment induced by high fluoride exposure. Methods: A total of 24 clean healthy Sprague-Dawley rats were randomly divided into control group (tap water containing 0.344 mg/L fluoride) and low-, medium-, and high-fluoride exposure groups (tap waters containing 10, 50, and 100 mg/L sodium fluoride, respectively). One male rat was cohabited with two female rats in the same group. After the offspring rats were weaned, 12 offspring rats (male/female ratio=1∶1) with a similar body weight in each group were subjected to the same treatment for the parental offspring. The offspring rats were sacrificed on the 60th day after birth. The weight of offspring rats was measured. Serum thyrotropin (TSH) , free triiodothyronine (FT(3)) , and free thyroxine (FT(4)) levels were measured by enzyme-linked immunosorbent assay. The learning and memory abilities of the rats were evaluated by Morris water maze test. The expression of mitochondrial fission 1 (Fis1) and mitofusin 1 (Mfn1) in blood was measured by Western blot. Results: The offspring rats in the medium-and high-fluoride exposure groups had significantly lower serum TSH and FT(4) levels than those in the control group (P<0.05). The place navigation test showed that the offspring rats in the medium-and high-fluoride exposure groups had significantly longer escape latency than those in the control group (P<0.05) , and the high-fluoride exposure group had a significantly longer escape distance than those in the control group (P<0.05). The spatial probe test showed that the offspring rats in the low-, medium-, and high-fluoride exposure groups had significantly shorter swimming time and distance in the target quadrant and total swimming time and distance than those in the control group (P<0.05). Compared with the offspring rats in the control group, those in the low-, medium-, and high-fluoride exposure groups had significantly higher expression of Fis1 (P<0.05) , and those in the low- and medium-fluoride exposure groups had significantly higher expression of Mfn1 (P<0.05) . Conclusion: High fluoride exposure can reduce the secretion of thyroid hormone and the abnormality of mitochondrial dynamics in peripheral lymphocytes may provide a clue to identifying the biomarkers of intellectual impairment induced by fluoride exposure.

Abstract
The study was conducted to investigate whether high-dose zinc methionine (Zn-Met) affected the safety of laying hens, including laying performance, hematological parameters, serum chemical parameters, organ index, and histopathology. A total of 540 20-week-old Hy-Line White laying hens was randomly allocated to 6 groups with 6 replicates of 15 birds each. Birds were fed diets supplemented with 0 (control), 70, 140, 350, 700, or 1,400 mg Zn/kg diet as Zn-Met. The experiment lasted for 8 wk after a 2-week acclimation period. Results showed that dietary supplementation with 70 or 140 mg Zn/kg diet as Zn-Met significantly increased average daily egg mass (ADEM), laying rate (LR), and feed conversion ratio (FCR) (P < 0.05) and lowered broken and soft-shelled egg ratio (BSER) (P < 0.05) in comparison with the control group; no significant differences were detected among hens fed with 0, 350, or 700 mg Zn/kg as Zn-Met (P > 0.05); hens administered 1,400 mg Zn/kg showed a significant increase in BSER and remarkable decreases in ADEM, LR, and FCR (P < 0.001). There were no significant differences among hens receiving 0, 70, 140, 350, or 700 mg Zn/kg as Zn-Met in serum chemical parameters (P > 0.05); supplementation with 1,400 mg Zn/kg as Zn-Met remarkably elevated the concentrations of serum total bilirubin (TBILI), glucose (GLU), uric acid (UA), and creatinine (CRE) (P < 0.001), and enhanced activities of serum glutamic oxalacetic transaminase (GOP) and alkaline phosphatase (AKP) (P < 0.001) compared with the control group. No significant histopathological changes were found in hens administered 0, 70, 140, 350, or 700 mg Zn/kg as Zn-Met, while significant histological lesions were observed in the heart, liver, lung, and kidney tissues of hens receiving 1,400 mg Zn/kg as Zn-Met. No significant differences were detected in hematological parameters or organ index (P > 0.05). In conclusion, a nominal Zn concentration of 700 mg/kg as Zn-Met is considered to be no-observed-adverse-effect level following daily administration to hens for 56 days.

Abstract
BACKGROUND To develop and to validate a new prognostic prediction system for patients admitted to the surgical intensive care unit (ICU), and to compare its performance with the Acute Physiology and Chronic Health Evaluation (APACHE) II system. METHODS The database was derived from three surgical ICUs in three hospitals. For each patient, demographic data, diagnosis, APACHE II score and hospital survival data were collected. The accuracy in outcome prediction of the APACHE II was assessed by means of receiver operating characteristic (ROC) analysis. The new prognostic system was developed by using a multiple logistic regression in the developmental data set and validated with the validation data set. RESULTS A total of 1,248 patients were included from three ICUs. The area under the ROC curve was 0.74 for the APACHE II score. The new prognostic system includes 18 variables. Goodness-of-fit tests indicated that the model performed well in the developmental and validation samples (p = 0.235 in the developmental data set and p = 0.297 in the validation set). The area under the ROC curve was 0.84 in the developmental sample and 0.77 in the validation sample for the new prognostic score. The area under the ROC curve was 0.71 in the validation sample for the APACHE II score. CONCLUSIONS Although APACHE II correlates with mortality for surgical ICU patients in Taiwan, its accuracy is not as good as in the original study. Mortality prediction performance improved with the use of the new, local scoring system.

Abstract
The authors describe a case of rhinosino-orbital mucormycosis with cavernous sinus thrombosis in association with internal carotid artery occlusion diagnosed by use of computerized tomography (CT) and magnetic resonance imaging (MRI). Cranial CT is a useful imaging tool in the diagnosis of rhinosinal invasive fungal disease and MRI offers excellent aid in the detection of intracranial extension. Early diagnosis and rapid institution of surgical debridement and antifungal therapy is the rule of thumb in treating this disorder. In our patient, surgically inaccessible bone lesion and involvement of the central nervous system are taken as major causes for his grave outcome. In addition, failure to advance appropriate amphotericin B dosage may also make the infectious process uncontrollable in this patient.

Abstract
BACKGROUND Serum transferrin receptor (sTfR) concentration has been recognized as a reliable laboratory indicator of iron deficiency in recent years. But its response to iron supplementation has not been investigated. METHODS We evaluated the sTfR concentrations in 15 patients diagnosed with iron-deficiency anemia, in 30 patients receiving maintenance hemodialysis (HD) with iron repletion and in 31 healthy controls. The serial changes of sTfR concentration and their correlation with serum ferritin in patients with iron deficiency under iron repletion were also examined in three patients. RESULTS In patients with iron-deficiency anemia, the sTfR concentration was 5.6 +/- 2.4 mg/ml, significantly higher than that in the control group (1.8 +/- 0.4 mg/ml) and patients receiving maintenance HD with iron repletion (1.7 +/- 0.5 mg/ml). The three patients with iron-deficiency anemia who received eight to 16 weeks of iron supplementation showed steady and significant decreases in sTfR concentration and significant increases in serum ferritin and transferrin saturation. However, the decreases in sTfR concentration did not occur immediately, as did the increases in serum ferritin and transferrin saturation, following iron repletion. There was a four-week delayed response in the decrease of sTfR concentrations as measured against serum ferritin and transferrin saturation. CONCLUSIONS sTfR concentration may not be as effective as an early index of iron repletion compared with serum ferritin and transferrin saturation.

Abstract
BACKGROUND Serum transferrin receptor (sTfR) is a transmembrane glycoprotein derived from erythroid precursors in the bone marrow. Its concentration provides a quantitative measure of total erythropoietic activity and an indication of functional iron deficiency. This study was conducted to investigate whether sTfR is a useful index of erythropoietic activity in chronic hemodialysis patients with poor response to maintenance recombinant human erythropoietin (rHuEPO) therapy. METHODS Using an enzyme-linked immunosorbent assay, sTfR concentration was measured in 67 uremic patients who had been on hemodialysis for a mean of 42 months (3-242 months). rHuEPO was administered three times a week to keep the hematocrit above 30%. Hemoglobin, red blood cell indices, serum ferritin, serum total iron binding capacity and unsaturated iron binding capacity were determined. Of the 67 patients, 35 who responded favorably to rHuEPO with hematocrits above 30% were categorized as Group I and 32 who did not attain the target hematocrit were categorized as Group II. As a control group, 31 healthy subjects were also investigated. RESULTS The serum iron, ferritin, transferrin iron saturation, dialysis efficiency and nutritional state were not different between groups of hemodialysis patients. The mean sTfR concentration was 2.1 +/- 0.6 micrograms/ml (range, 1.15-3.53 micrograms/ml) in Group I patients, compared with 1.9 +/- 0.9 micrograms/ml (range, 1.03-2.65 micrograms/ml) in Group II. The difference was not significant. In addition, the mean sTfR concentration of 1.8 +/- 0.4 micrograms/ml (range, 0.86-2.76 micrograms/ml) in the healthy controls was not significantly different from Groups I and II. CONCLUSIONS sTfR concentration cannot be used to distinguish good from poor rHuEPO responders among chronic hemodialysis patients who have elevated serum ferritin (> 300 micrograms/l) and transferrin iron saturation (> 25%) during the course of maintenance rHuEPO therapy.

Abstract
BACKGROUND To evaluate the appearance of the arrangement of the superior mesenteric artery (SMA) and superior mesenteric vein (SMV) on computed tomography (CT) in normal patients and in patients with abdominal masses. METHODS One hundred seventy-seven consecutive abdominal CT examinations of 143 adults and two children were reviewed. The relationship of the SMV to the SMA was recorded at four locations: the beginning of the mesenteric vessels and levels 3 cm, 6 cm, and 9 cm caudad to the beginning. The relationship of the SMV to the SMA was divided into four quadrants in relation to the SMA: I, ventral right or directly ventral; II, dorsal right or directly right; III, dorsal left or directly dorsal; and IV, ventral left or directly left. RESULTS In the beginning of the SMV-SMA complex and levels 3 cm, 6 cm, and 9 cm caudal to the beginning, the SMV was located in quadrant I in 146, 84, 69, and 43 examinations, in quadrant II in 31, 93, 71, and 27 examinations, in quadrant III in zero, zero, five, and three examinations, and in quadrant IV in zero, zero, nine, and 15 examinations, respectively. The cases with SMV inversion had neither malrotation nor adjacent tumor compression. All the cases with an adjacent tumor-induced compression of the SMV-SMA complex had a normal SMV-SMA relationship. CONCLUSION In the first 3 cm, the SMV is always to the right of the SMA. Caudal to the level of 6 cm, the SMV may be located to the left of the SMA without evidence of malrotation. A midgut nonrotation is more likely to be present when a proximal SMV inversion is coexistent with a rightward direction of the proximal jejunal vessels. A hypothetical depiction of the step-by-step change of the SMV-SMA relationship during embryologic development may explain the arrangement patterns of the mesenteric vessels in normal rotation and midgut nonrotation.

Abstract
To determine the location of the duodenojejunal junction (DJJ) at computed tomography (CT), we retrospectively reviewed 309 consecutive CT examinations. These included 162 men and 127 women (mean age = 57 years old, range = 11-85 years old). Some people received more than one examination. The clinical indications included various kinds of neoplasms, inflammations, congenital lesions, trauma, and other conditions. The DJJ was defined as the first sectioned ascending duodenum whose major part lies to the right side of the crossing part of the inferior mesenteric vein over the immediate beginning of the jejunum. Forty-nine examinations were excluded due to distortion of the DJJ by contiguous pathologic processes or nonadministration of intravenous contrast medium. In 36 examinations, the junctions were not identified. In the successfully identified 224 examinations, the DJJ was located to the left in 75 (33.5%), in the left half in 87 (38.8%), and in the right half or to the right of the vertebral body in 4 (1.8%) examinations. The midline of the DJJ was along the left margin and in the midline of the vertebral body in 53 (23.7%) and 5 (2.2%) examinations. In the anteroposterior direction, it was totally in front of the aorta in 189 (84.4%) and within the projected contour of the aorta in 11 (4.9%) examinations. The midline of the DJJ was along the anterior margin of the aorta in 24 (10.7%) examinations. Its cephalocaudal position was at the upper L1 in 36 (16.1%), lower L1 in 70 (31.3%), upper L2 in 75 (33.5%), and lower L2 in 21 (9.4%) examinations even though it ranged from upper T12 to upper L3.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
An 82-year-old man had his third episode of melanotic stool. Two previous workups had failed to localize the source of bleeding. A Tc-99m labeled RBC scan visualized the gallbladder early in the study. Administration of sincalide visually decreased the activity, confirming gallbladder activity. Three months later, at his second surgery, hepatic metastases were finally identified as the source of bleeding. In retrospect, the hepatic activity is inhomogeneous with at least two cold defects that could have represented hepatic metastases.

Abstract
The effect of adenosine on the neuromuscular blockade induced by vecuronium and the capacity of neostigmine to reverse this combined blockade were studied in 30 cats on a standard sciatic nerve--tibialis anterior muscle preparation. Adenosine infused to 6 cats at a constant rate (3.9 +/- 1.1 mg/kg/min) to produce a stable 50% reduction of the mean arterial pressure did not affect neuromuscular transmission. At the same 50% reduction of the mean arterial pressure by adenosine or sodium nitroprusside infusion in another 15 cats, adenosine (n = 9) significantly potentiated vecuronium-induced neuromuscular blockade, but sodium nitroprusside (n = 6) did not. Neostigmine antagonized the neuromuscular blockade of similar degrees produced either by the combination of adenosine with vecuronium in the above 9 cats or by vecuronium alone in the remaining 9 cats. There was no significant difference in the doses of neostigmine given. Because no potentiation was found at the same level of hypotension induced by sodium nitroprusside, the potentiation effect of adenosine on neuromuscular blockade is not likely to be due to the hypotensive effect of adenosine, but may be due to impairment, by adenosine, of acetylcholine release from motor nerve endings. We conclude that adenosine potentiates neuromuscular blockade by vecuronium and that neostigmine can be expected to reverse this combined blockade.

Abstract
The patients received thoracotomy usually suffered from significant severe pain postoperatively, which accompanied with impaired pulmonary function or increased incidences of atelectasis and pneumonia. So adequate analgesia for those patients is indicated. The purpose of this study is to investigate the efficiency of patient-controlled analgesia (PCA) and determine whether it is better than conventional analgesia or not. Twenty-six patients, ASA physical status class I and II, were randomized into two groups: PCA and intramuscular (IM). The effect on pain relief was assessed by a visual analogue pain scale (VAPS) q 4 h postoperatively for two days. Forced vital capacity (FVC) and the questionnaire of nocturnal sleep disturbance by pain were evaluated preoperatively, the first, second postoperative mornings. As result of this study, the patients of PCA group get less pain than IM group after the first and second days of surgery. VAPS values are 3.7 +/- 1.1, 2.8 +/- 0.8 and 6.1 +/- 0.9, 5.3 +/- 1.1 respectively pertaining to PCA and IM groups (p less than 0.05). The patients of IM group get more disturbance of nocturnal sleep than PCA group at initial two nights of postoperation as well (p less than 0.05). It is manifest to look out the significant difference between these two groups in accordance with FVC ratio records of post-surgery vs presurgery at initial two days after surgery on the subject of respiratory function recovery. PCA group are 46.46 +/- 7.29%, 52.25 +/- 8.32% in a condition of more progress on lung function recovery than IM group of 38.13 +/- 10.25%, 42.15 +/- 7.82% (p less than 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)
