Objective:To investigate the iodine nutrition status of key population in Fuzhou City, and to provide scientific basis for adjusting intervention strategies.Methods:From March to October 2021, a survey was conducted on iodine nutrition status of key population in 12 counties (cities, districts) of Fuzhou City. Each county (city, district) was divided into 5 sampling areas according to the east, west, south, north and middle directions. One township (street) was selected from each area, and 40 non-boarding children aged 8 - 10 (age balanced, half male and half female) from one primary school and 20 pregnant women (early, middle and late pregnancy balanced) were selected as survey subjects. Household salt samples and random urine samples were collected, and the salt iodine and urine iodine levels were tested by direct titration and arsenic and cerium catalytic spectrophotometry, respectively. Children's thyroid volume was measured by B-ultrasonography. At the same time, in cooperation with Fuzhou Maternal and Child Health Hospital, the thyroid stimulating hormone (TSH) testing results of heel blood of full-term natural delivery newborns in Fuzhou City in 2021 were collected.Results:A total of 2 400 children were monitored for salt iodine, urine iodine and goiter. The median salt iodine was 24.40 mg/kg, with an iodine salt coverage rate of 93.04% (2 233/2 400), a qualified rate of iodized salt of 97.40% (2 175/2 233), and a consumption rate of qualified iodized salt of 90.62% (2 175/2 400). The median urine iodine was 181.47 μg/L. The rate of goiter was 1.04% (25/2 400). A total of 1 200 pregnant women were monitored for salt iodine and urine iodine. The median salt iodine was 24.10 mg/kg, the coverage rate of iodized salt was 91.08% (1 093/1 200), the qualified rate of iodized salt was 97.90% (1 070/1 093), and the consumption rate of qualified iodized salt was 89.17% (1 070/1 200). The median urine iodine was 128.10 μg/L. The median TSH level in the heel blood of 14 242 newborns was 3.38 mU/L, and the proportion of TSH level > 5 mU/L was 30.96% (4 410/14 242).Conclusions:In 2021, children in Fuzhou City are at an appropriate level of iodine, but pregnant women are insufficient of iodine. We should continue to maintain comprehensive prevention and control measures mainly based on salt iodization, provide health education for pregnant women, and strengthen monitoring of TSH level in newborns.

A study of the practice of "three early education" combined with medical ethics literacy cultivation to improve medical students' post competence / 中华医学教育探索杂志

Clinical post competence and medical ethics literacy are the key qualities that applied medical talents should have. The synergy of medical education is an effective way to deepen the reform of competence-oriented medical education. Under the background of synergy of medical education and considering the orientation of training applied medical talents in our college, we explore a progressive path of "three early education", which means early exposure to specialties, early exposure to practice, and early exposure to clinical practice. Meanwhile, we strengthen the cultivation of medical students' medical ethics literacy throughout the whole process of "three early education", laying a solid foundation for medical students before they enter the stage of clinical practice training. Practice shows that the progressive "three early education" mode and the cultivation of medical ethics literacy throughout the whole process can effectively improve medical students' clinical post competence.

One hundred adult abdominal CT were collected to measure the distance between the extraperitoneal fat of anterior abdominal wall and the rectus abdominis and the anterior midline at L 2-S 1 segment. One hundred and fifty adult lumbar MRI were collected to measure the distance between the anterior great vessels and the anterior midline of the intervertebral disc. Fifty-six cases of lumbar fusion were performed by minimally invasive anterior lumbar extraperitoneal approach, including 25 males and 31 females, aged 29-71 years. L 2-L 4 in 8 cases was performed by left rectus abdominis oblique incision, and L 4-S 1 in 48 cases was performed by median left transverse incision, with a length of about 8 cm, the complications related to the surgical approach were evaluated. Results:L 2-L 4 was proximal to the arcuate line, the posterior sheath of rectus abdominis adhered to the peritoneum, which was easy to rupture when separated; the peritoneum gradually thickened from the outer edge of the sheath of rectus abdominis and extraperitoneal fat appears. L 4-S 1 could be exposed distal to the arcuate line, the posterior side of rectus abdominis was extraperitoneal fat, the extension of arcuate line to the lateral abdominal wall would be slightly separated proximally, and there were multiple iliopsoas veins in the medial side of psoas major muscle. L 5S 1 was between the right common iliac artery and the left common iliac vein far, the median sacral vessel was small or absent, and the sympathetic nerve was to the left. Extraperitoneal fat appeared 36.2±9.9 mm, 35.2±11.6 mm and 27.6±11.2 mm away from the outer edge of rectus abdominis at L 2, 3, L 3, 4 and L 4, 5 segments respectively, and covered the posterior side of rectus abdominis and reached the midline at L 5S 1 segment. The left edge of abdominal aorta was 14.9±5.1 mm, 13.9±4.6 mm and 19.7±5.9 mm away from the midline at L 2, 3, L 3, 4 and L 4, 5 level respectively; the inferior vena cava was located on the right side of the midline at L 2, 3 and L 3, 4 level, crossed the midline 4.6±8.7 mm at L 4, 5 level. At L 5S 1 level, the left common iliac vein and the right common iliac artery were 14.6±6.8 mm and 17.6±5.3 mm away from the midline respectively. Seventy-six patients were successfully and fully exposed by small incision through extraperitoneal approach. 1 case of L 4, 5 had iliac lumbar vein tear and hemostasis with bipolar electrocoagulation. The operation time was 70-120 min, with an average of 90 min; Intraoperative bleeding was 15-70 ml, with an average of 30 ml. No severe complication such as nerve and great vessel injury occurred.

Research progress in molecular pathology of salivary gland carcinoma and clinical application / 国际生物医学工程杂志

Salivary gland cancer includes a group of heterogeneous malignant tumors. The latest WHO classification of head and neck tumors divides salivary gland cancer into 22 histopathological subtypes. The most common clinical subtypes include mucoepidermoid carcinoma, adenoid cystic carcinoma, salivary duct carcinoma, acinar cell carcinoma and secretory carcinoma, etc. The histomorphology of the subtypes of salivary gland cancer overlaps, making diagnosis and differential diagnosis difficult. The main treatment for salivary gland cancer is tumor resection and postoperative radiotherapy as appropriate. Even in cases of local progression, recurrence and metastasis, the treatment options available are limited, mainly palliative treatment. Accurate determination of tumor receptor expression, genome and pathway changes is the key to changing the prognosis of patients with local progression or distant metastasis. In this paper, the known genetic mutations, amplifications and protein expression profiles of common salivary gland cancer histological subtypes was summarized, and the significance of the above-mentioned molecular genetic changes for disease diagnosis, future research and personalized targeted therapy was analyzed.

Analysis on the survey results of iodine content in drinking water in Fuzhou, 2017 / 中华地方病学杂志

Objective:To understand the level and distribution of iodine contents in drinking water in Fuzhou City so as to provide evidence for prevention of iodine deficiency disorders and health intervention.Methods:In 2017, a township-level water iodine survey was carried out in 12 counties (cities, districts) under the jurisdiction of Fuzhou City, with a township as a unit, and carry out administrative village-level water iodine survey in township with the median water iodine ≥ 10 μg/L. The water samples of residents' drinking water were collected according to different water supply methods (centralized water supply, mixed water supply and decentralized water supply), and the water iodine content was determined. The water iodine content less than 10 μg/L means iodine deficiency in the external environment. The iodine contents in drinking water of residents in different areas, different water supply methods and different water source types were compared and analyzed.Results:A total of 172 townships in 12 counties (cities, districts) were investigated for water iodine, and 1 630 water samples were collected and tested, the median water iodine was 2.8 μg/L and the range was 0.0 - 130.3 μg/L. At the township-level, the median range of water iodine was 0.4 - 11.2 μg/L. A total of 75 administrative villages were investigated in 4 townships with a median water iodine ≥ 10 μg/L, the median water iodine range was 0.5 - 19.8 μg/L. At the counties (cities, districts) level, the medians of water iodine were all less than 10 μg/L. Among them, the medians of water iodine in inland areas and coastal areas were 2.0 and 4.0 μg/L, respectively, and the difference between different areas was statistically significant ( Z = - 15.70, P <0.01). The medians of water iodine for centralized water supply, mixed water supply and decentralized water supply were 4.1, 2.7, and 3.4 μg/L, respectively, and the difference between different water supply methods was statistically significant ( H = 19.38, P < 0.01). The medians of water iodine in surface water and well water were 2.4 and 3.1 μg/L, respectively, the difference between different water source types was statistically significant ( Z = - 6.23, P<0.01). Conclusions:Iodine deficiency of external environment is common in Fuzhou City, and there is no distribution of high iodine in water source. It is necessary to strengthen the monitoring of iodine deficiency disorders, establish a long-term working mechanism suitable for the level of economic and social development, and consolidate the achievements of prevention and control.

Outcomes of Reinterventions for Children with Postoperative Pulmonary Venous Restenosis.

This report aims to summarize and evaluate the efficacy and experience of reintervention for children with postoperative pulmonary venous restenosis. Clinical data from 61 patients with postoperative pulmonary venous restenosis who underwent reintervention at Shanghai Children's Medical Center (SCMC) from September 2009 to June 2018 were retrospectively analyzed. The patients comprised 38 boys and 23 girls, with a mean age of 15.4 ± 12.6 months (2-83 months) and a mean weight of 8.1 ± 3.4 kg (3.7-18.5 kg). The mean pulmonary venous velocity was 2.31 ± 0.47 m/s (1.86-3.22 m/s). Primary disease included 48 cases of total anomalous pulmonary venous drainage, nine cases of partial anomalous pulmonary venous drainage, and four cases of primary pulmonary venous stenosis. The reintervention procedures included 34 cases using the sutureless technique, ten cases using bovine pericardium enlargement, three cases using blunt enlargement, four cases of balloon dilatation, one case using stent implantation and nine cases involving more than two surgical methods. The early postoperative pulmonary venous velocity was 1.16 ± 0.20 m/s. There were five in-hospital deaths, resulting in a mortality rate of 8.2%. Fifty-six survivors were followed for 52.8 ± 46.5 months (6-103 months) with no delayed deaths. Echocardiography showed pulmonary venous anastomosis and diameter growth after reintervention, exhibiting a mean growth speed of 0.026 ± 0.013 cm/month (p < 0.05) and a mean velocity of 1.24 ± 0.26 m/s; five patients experienced varying degrees of pulmonary venous obstruction (> 1.6 m/s), but did not require reoperation. Postoperative pulmonary venous restenosis is a common complication after surgery for pulmonary venous malformations. Reintervention should be performed in the early period of pulmonary venous obstruction. Growth of pulmonary venous anastomoses was observed after performing the sutureless technique, bovine pericardium enlargement and blunt enlargement. Although balloon dilatation has a good effect in the early postoperative period, its restenosis rate is high, and strict mid- to long-term follow-up is needed.

In the J group,the tibia anterior translation was measured in four different conditions in the same joint: intact knee joint,knee joint without ACL, ACL anatomic reconstruction by interference screw fixation, and ACL anatomic reconstruction by interference screw fixation with corrected bone tunnel location. Results 1) With 7 mm, 8mm and 9 mm interference screw fixation, graft position shift were (2.36±0.11) mm, (2.72±0.06) mm and (3.00±0.06) mm respectively. 2) Graft length change: graft length change in Retrobutton group and corrected bone tunnel group were less than 3 mm, while graft length change in those fixed with interference screw were stretched in more than 3 mm. 3) Study of tibia anterior translation: there was no difference among the intact group, the anatomic group and the corrected group at 0° and 15°. However, the difference was found between the intact group and other groups at 30°、60° and 90° of flexion, as well as between these two reconstructed methods at 20° joint flexion (P＜0.05). Conclusion In both isometric and anatomic ACL reconstruction with interference screw, the graft is pushed tightly toward the femoral tunnel wall, which shifts the graft away from the desired position. In our study we find out that the corrected location of the femoral bone tunnel significantly improves the isometry of ACL reconstruction and anatomic reconstruction.

Efficacy analysis of endovascular graft exclusion for the treatment of 24 patients with infra-kidney abdominal aortic aneurysms / 中国医师进修杂志

Objective To investigate the efficacy and the indication and the management of perioperative complications in treatment of infra- kidney abdominal aortic aneurysm (AAA) by using endovascular graft exclusion (EVGE). Methods From April 2006 to September 2008, 24 patients with infra- kidney abdominal aortic aneurysms were diagnosed by contrast-enhanced CT or MRI scan. Vascular access was obtained through the bilateral femoral artery after arteriotomy and stent-graft was deployed into AAA of below the renal artery to occlude the left over cavity of AAA. The stent- graft was extended and anchored to the both side wall of AAA, the blood flow enter into the arteria iliaca communis through the sten't.Results Stent-graft deployment was successfully performed in all the patients. Immediate aortography after the procedure showed no leakage in 20 patients and the type Ⅰ minor leakage in 4 patients. No stent movement or organ and both lower extremities ischemia was found at the early post operative stage in all the patients. Six months after the operation, in all the 24 patients, contrast-enhanced CT scan showed the disappearance of the aneurysm and thrombosis at the level of the stent. Conclusions EVGE is simple,minimally invasive,less complication and quick recovery after operation. Thus it becomes first choice for the treatment of AAA for the elder patients.

Thinking and look forward to clinical study of allergic rhinitis by treatment of traditional Chinese medicine / 中国中药杂志

Allergic rhinitis (AR) is one kind of nose mucous membrane inflammation reactiveness disease, which is mediated by IgE for the environment sensitizin. The major clinical symptoms are: nose itch, the sneeze, nasal discharge, nasal obstruction and so on. It is thought that the acient disease named "Bi Qiu" has included AR. By comparing the AR clinical manifestation characteristic with trditional Chinese medicine (TCM) "Feng/wind" induced disease characteristic and the "Feng/wind" disease clinical manifestation characteristic, we can know that AR should belong to the "Feng/wind" disease category of TCM. It is shown that the "Feng/ wind" medicine is the most windly appeared in AR treatment formulas of TCM clinical research data (in each formular) in the past 10 years. To aim directly at three knids of problem in TCM clinical research, we discussed five problems which should pay close attention to the feature research, therefor to provide a mirror for AR clinical and experimental studies by TCM.

Influence of nursing intervention on caesarean section rate in grassroots hospitals / 中国实用护理杂志

Objective To observe the effect of nursing intervention on caesarean section rate in grass-roots hospitals. Methods 240 parturient women who were to infanticipate were divided into the experimental group and the control group with 120 patients in each group according to hospitalization sequence. Parturient women in the experimental group received nursing intervention with new nursing model during the delivery, while women in the control group just finished parturition using routine procedures. The caesarean section rate of the two groups were compared with χ2 test. Results The caesarean section rate of parturient women in the experimental group was significantly lower than that in the control group. Conclusions Nursing inter-vention has certain effect on decreasing the caesarean section rate in grassroots hospitals.
