Study on the influencing factors in pupils' disequilibrium refractive development / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To investigate the influencing factors of disequilibrium refractive development in children aged 6-12 years old.METHODS: A total of 607 children with a mean age of 8.2±1.8 years old from two primary schools in Binhai New Area of Tianjin in December 2019 were selected by cluster sampling for optical biometry measurement(axial length and equivalent corneal power), cycloplegia refractive examination and questionnaire survey.RESULTS: The childrens'spherical equivalent was -0.11±1.63D, binocular spherical equivalent difference was -0.08±0.64D and absolute value of spherical equivalent difference was 0.41±0.49D. There were 56 children with anisometropia and 551 children without anisometropia. There was no difference in the absolute value of binocular corneal power difference between anisometropia and non-anisometropia group(0.30±0.34D vs 0.27±0.24D, P=0.430). But the absolute value of axial difference was significantly different(0.67±0.39mm vs 0.13±0.13mm, P=0.005). Multivariate linear regression analysis showed that weekly usage time of phones/computers, weekly close work hours, weekly visual fatigue times and habitual reading distance were the influencing factors of refractive imbalance development(the absolute value of binocular spherical equivalent difference). Habitual reading distance and handedness in writing are the influencing factors of the developmental bias of refractive imbalance(binocular spherical equivalent difference).CONCLUSION: Children aged 6-12 years old who spend more time on phones/computers, and have prolonged close work, more times of visual fatigue and close habitual reading distance may increase the degree of refractive imbalance. Children with right-handed handwriting and severe left or right head deviation have a deeper degree of myopia in the right eye than in the left eye.

Relationship between sense of coherence and anxiety-depression in elderly patients with gestational diabetes mellitus / 中国实用护理杂志

Objective:To study relationship between sense of coherence and anxiety-depression in elderly patients with gestational diabetes mellitus (GDM).Methods:A total of 360 gestational pregnant women who were admitted to the hospital from November 2018 to January 2019 were enrolled by simple random sampling. The Sense of Coherence Scale (SOC-13), Self-rating Anxiety Scale (SAS) and Self-rating Depression Scale (SDS) were applied to survey them. The scores of SOC-13, SAS and SDS of them were observed. The correlation between sense of coherence and anxiety-depression was analyzed.Results:Among 360 gestational pregnant women, there were 98 cases with age-appropriate GDM (less than 35 years old, age-appropriate GDM group), 159 cases with advanced GDM (not less than 35 years old, advanced GDM group), and 103 advanced non-GDM pregnant women (advanced non-GDM group). Arranging SOC-13 scores from low to high, the corresponding order was advanced GDM group, age-appropriate GDM group and advanced non-GDM group (with scores of 52.25±10.57, 60.18±9.31, 63.24±8.57) ( F value was 45.109, P<0.01). SAS score was the highest in advanced GDM group, followed by age-appropriate GDM group and advanced non-GDM group (50.33±5.85, 45.62±6.77, 42.26±5.34) ( F value was 59.598, P<0.01). SDS score was the highest in advanced GDM group, followed by age-appropriate GDM group and advanced non-GDM group (52.59±5.62, 47.64±4.83, 45.48±4.72) ( F value was 65.419, P<0.01). SOC-13 of 160 advanced GDM patients was negatively correlated with SAS ( runderstanding sense=-0.532, rcontrol sense=-0.653, rsignificance sense=-0.631, rtotal score=-0.735, all P<0.01). And SOC-13 was negatively correlated with SDS ( runderstanding sense=-0.438, rcontrol sense=-0.562, rsignificance sense=-0.581, rtotal score=-0.685, all P<0.01). Conclusions:Sense of coherence in elderly GDM patients is negatively correlated with anxiety and depression. Nursing staff can improve their anxiety and depression by intervening in sense of coherence.

Reproductive health status and its influencing factors of female employees in an automobile manufacturing industry / 中国职业医学

OBJECTIVE: To analyze the reproductive health status of female employees in an automobile manufacturing industry and its influencing factors. METHODS: By a method of convenient sampling, 989 female employees of an automobile manufacturer were selected as the study subjects. The Female Employees′ Reproductive Health Status Questionnaire was used to investigate and analyze the influencing factors. RESULTS: The prevalence of abnormal menstruation was 23.7%(234/989). The abnormal menstruation was mainly the menstrual cycle disorder, with the prevalence of 15.4%(152/989). The prevalence of reproductive tract infection was 39.1%(387/989), and the top 2 types of infection were cervicitis(12.7%) and vaginitis(12.1%). The results of multivariate logistic regression analysis showed that the risk of abnormal menstruation in night shift workers was higher than that in day shift workers(P<0.05). The risk of abnormal menstruation increased in female workers with the increase of work intensity(P<0.05). Female workers with a history of abortion had higher risk of abnormal menstruation and reproductive tract infection than those without a history of abortion(all P<0.05). Female workers with abnormal menstruation had a higher risk of reproductive tract infection than those with normal menstruation(P<0.01). Married employees had a higher risk of reproductive tract infection than unmarried ones(P<0.01). CONCLUSION: The reproductive health of female workers in the automobile manufacturing industry is related to their marital status, work shift, work intensity and history of abortion.

Therapeutic observation of grain-sized moxibustion for chemotherapy-induced myelosuppression for non-small cell lungcancer / 针灸推拿医学（英文版）

Objective: To observe the clinical efficacy of grain-sized moxibustion in treating chemotherapy-induced myelosuppression for non-small cell lung cancer (NSCLC) and its effect on quality of life (QOL). Methods: Eighty NSCLC patients admitted to the Inpatient Department of Zhejiang Cancer Hospital between September 2016 and March 2018 were recruited and divided into an observation group and a control group by random number method, with 40 cases in each group. The two groups both received chemotherapy with paclitaxel plus cisplatin (TP regimen). The control group received oral administration of leucogen tablets starting from the first day of chemotherapy, 20 mg each time, three times a day, for consecutive 14 d; the observation group was additionally given grain-sized moxibustion, once a day, five days per week at a two-day interval, until the fourteenth day. The myelosuppression severity was observed and compared between the two groups prior to chemotherapy, at the 3rd, 7th and 14th days of chemotherapy; the QOL in the two groups was evaluated before chemotherapy, at the 14th and 21st days of chemotherapy. Results: Regarding myelosuppression, the peripheral blood indicators increased significantly at the 3rd day of chemotherapy in both groups (P<0.05 or P<0.01); at the 7th and 14th days of chemotherapy, the peripheral blood indicators presented a decreasing tendency in the two groups, but the level in the observation group was still significantly higher than that before chemotherapy (P<0.01); at the 3rd, 7th and 14th days of chemotherapy, the peripheral blood indicators in the observation group were higher than those in the control group (P<0.05 or P<0.01); the occurrence rate of myelosuppression in the observation group was significantly lower than that in the control group (P<0.01). The QOL score in the observation group was markedly higher than that in the control group at the 14th and 21st days of chemotherapy (both P<0.05). Conclusion: Grain-sized moxibustion can effectively improve myelosuppression after chemotherapy for NSCLC, reducing its occurrence and enhancing the patient's QOL.

Investigation of free ticks carrying CRT and compound infection with SFTSV in Yanbian area of Jilin Province / 中华疾病控制杂志

Objective To understand the condition of tick carrying CRT(Candidatus rickettsia tarasevichiae) and compound infection with SFTSV(Sever fever thrombocytopenia syndrome virus) in Yanbian area of Jilin province. Methods Free ticks were collected from 6 counties including Yanji, Wangqing, Hunchun, Dunhua, Antu and Helong in the Korean Autonomous Prefecture of Jilin Province(Yanbian Prefecture) by using the flagging, and they were classified morphologically. The CRT and SFTSV in ticks were detected by Nest PCR(Nested polymerase chain reaction) and Real Time RT-PCR(Real-time Quantitative polymerase chain reaction) methods. Target DNA sequencing was performed for CRT positive products, and the homology of gene sequence and phylogenetic relationship were analyzed. Results A total of 1032 ticks were collected in this study, including ixodes persulcatus (35.56%) and dermacenter silvarum (20.64%). haemaphysalis japonica (20.45%), haemaphysalis longicornis (10.47%), haemaphysalis concinna (8.33%),others( 4.55%). The CRT was detected from the Ixodes persulcatus, Haemaphysalis longicornis, Haemaphysalis japonica Dermacentor silvarum. The MIR(Minimum infection rate per 100 ticks) of CRT was 10.47%.The SFTSV was detected from the Haemaphysalis-concinna, Haemaphysalis-japonica,Ixodes-persulcatus,Haemaphysalis-longicornis,Dermacentor-silvarum. The MIR of SFTSV was 2.52 %. Three species of ticks, including Ixodes persulcatus(2.45%), Haemaphysalis japonica(1.42%), and dermacentor silvarum(0.47%), had CRT and SFTSV compound infections, and the MIR of two pathogens compound infections was 1.26 %. In this study, the gene sequence of CRT positive PCR products ompA and 17kDa with nucleotide sequence of Xinyang plant of HeNan XinYang strain (KX365196.1),had homology of 100%. Phylogenetic analysis showed that CRT ompA and the HeNan XinYang strain (KX365196.1) gene sequences formed a cluster in Yanbian, while the 17 kDa gene formed an independent branch. Conclusions For the first time, CRT was detected from free ticks in Yanbian area of Jilin Province, and it was found that Ixodes persulcatus may be the main medium of transmission of the pathogen. At the same time, it was found that CRT and SFTSV have compound infection in ticks of Yanbian area. Therefore, it can be clearly identified that Yanbian area in Jilin Province is the natural source of CRT, and there are two pathogenic compound infections in the local ticks.

The Characteristics and Survival Outcomes in Patients Aged 70 Years and Older with Nasopharyngeal Carcinoma in the Intensity-Modulated Radiotherapy Era / Journal of the Korean Cancer Association, 대한암학회지

PURPOSE: We aim to examine nasopharyngeal carcinoma (NPC) characteristics and survival outcomes in patients aged 70 years and older in the intensity-modulated radiotherapy (IMRT) era. MATERIALS AND METHODS: From 2006 to 2013, 126 non-metastatic NPC patients aged ≥ 70 years who were treated with IMRT +/‒ chemotherapy were included. Adult Comorbidity Evaluation 27 (ACE-27) was used to measure patient comorbidities. The overall survival (OS) and cancer-specific survival (CSS)were calculatedwith the Kaplan-Meier method, and differenceswere compared using the log-rank test. The Cox proportional hazards model was used to carry out multivariate analyses. RESULTS: For the entire group, only two patients (1.6%) presented stage I disease, and up to 84.1% patients had stage III-IVB disease. All patients had a comorbidity score of 0 in 24 (19.0%), 1 in 45 (35.7%), 2 in 42 (33.3%), and 3 in 15 (11.9%) patients. The main acute grade during radiotherapy was 3-4 adverse events consisting of mucositis (25.4%), bone marrow suppression (16.7%), and dermatitis (8.7%). After treatment, four patients (3.2%) developed temporal lobe injury. Five-year CSS and OS rates were 67.3% (95% confidence interval [CI], 58.6% to 77.4%) and 54.0% (95% CI, 45.6% to 63.9%), respectively. Five-year OS was significantly higher for ACE-27 score 0-1 than ACE-27 score 2-3 (72.9% and 39.9%, respectively; p 0.05). CONCLUSION: Our findings suggest IMRT +/– chemotherapy has a manageable toxicity and provides an acceptable survival in patients aged ≥ 70 years with NPC. ACE-27 score was significantly associated with survival outcomes in this group population.

Distribution of choroidal thickness and its influencing factors in undergraduate students of Tianjin Medical University / 中华眼底病杂志

Objective To explore the distribution ofchoroidal thickness and its influence factors in university students.Methods A cross-sectional study.A total of 896 eyes of 896 college students were included in the study.Among them,there were 350 males (350 eyes) and 546 females (546 eyes).All the eyes were right eyes.The average age was 19.18 ± 1.36 years old.According to the spherical equivalent refraction (SER),the eyes were divided into non-myopia group,low myopia group,moderate myopia group and high myopia group,which were 59,251,356 and 230 eyes,respectively.The subfoveal ChT (SFCT) was measured using a swept-frequency source optical coherence tomography scanner.According to the ETDRS,the choroid within 6 mm of the fovea was divided into three concentric circles centered on the fovea of the macula,which were the central area with a diameter of 1 mm,the inner ring area of 1-3 mm and the outer ring area of 3-6 mm.The outer ring area of 3-6 mm has a total of 9 zones.The inner ring and outer ring 4 regions were superior,inferior,nasal and temporal,respectively.The distribution characteristics of ChT in different regions,genders and diopter groups were observed.Bivariate correlation analysis were used to analyze the correlation of ChT and SER,axial length (AL).Results The average SFCT of 896 eyes was 221.28± 67.35 μm.The mean SFCT of males and females were 227.20 ± 69.38 and 217.50± 65.80 μm,respectively.The difference of SFCT between different genders was statistically significant (t=2.075,P=0.038).Compared with the central region ChT,there was no significant difference in ChT between the outer ring and the outer region (t=0.086,P=0.932).The difference of ChT in other regions was statistically significant (t=-21.973,-5.818,36.328,-3.065,-18.017,-10.595,57.007;P＜0.001,＜0.001,＜0.001,＜0.002,＜0.001,＜0.001,＜0.001).In the horizontal direction,ChT gradually thickens from nasal to temporal (F=2 251.558,P＜0.001);in the vertical direction,ChT gradually decreases from superior to the central,but have a little increased from central to inner inferior,then decreased to outer inferior again (F=45.425,P＜0.05).Correlation analysis showed that SFCT was negatively correlated with AL (r=0.478,P＜0.01) and a negative correlation with axial length (r=-0.395,P＜0.01),and positively correlated with SER (r=0.478,P＜0.01).SFCT decreased by 12.29 μm for every in myopic refractive error of 1 D,or by 20.14 μm for every increase in AL of 1 mm.Conclusions ChT is changed by different location.The horizontal direction is gradually thickened from nasal to temporal.The vertical direction is thicker than the center.The inferior inner ring area is thicker than the outer ring area.Gender,SER and AL are the influencing factors of SFCT.

Aconitum in treatment of rheumatoid arthritis: benefit-risk assessment / 中国中药杂志

Rheumatoid arthritis (RA) has the characteristics of long course of disease and difficulty in treatment. The conventional therapy may easily induce adverse drug reactions or events (ADR/ADE) due to the long-time medication. Thus, it should be given special attentions to treatment benefit and medication risk of RA patients. Aconitum, a kind of toxic traditional Chinese herbs, is an important complement therapy for RA, with some controversy in clinical application. Coming straight to the practical problem of combined use of traditional Chinese medicines (TCM) and Western medicines (WM), this study conducted quantitative assessment on the benefits and risks of Aconitum using combined with WM or not, which was carried out by the method of multi-criteria decision analysis model. RevMan 5.2 software was used to separately analyze the results of every index of 21 random clinical trials (RCTs) of Aconitum exclusive use in the treatment of RA, and 49 RCTs of Aconitum combined use with WM. The merged results indicated that as compared with the conventional therapy of WM, no matter the exclusive use or the combined use of Aconitum could improve the efficacy and decrease the incidence of ADR/ADEs. Based on the benefit-risk assessment decision tree of RA treatment, Hiview 3 software and Crystal Ball Monte Carlo simulation were used to calculate the benefit value, risk value and benefit-risk value of Aconitum exclusive use and the combined use of Aconitum with WM. The results showed that the combination therapy had significantly better benefits than Aconitum exclusive using, difference value was 15, (95%CI[9.72, 20.25]), but the risk of combined use was higher difference value=23, （95%CI[15.57, 30.55]）. In comprehensive consideration of the benefit and risk, the total benefit-risk value of using Aconitum alone was 58, while that of the combination therapy was 55, and the probability of the former superior to the latter was 81.07%. The study showed that Aconitum was the important therapy to supply RA treatment. In clinical application, the patient's acceptability of benefit and risk need to be considered; if patients cannot bear the risk, the combination use of Aconitum and WM is not recommended.

Protective Effect of Radix Rhapontici Water Extract on Tert-Butyl Hydroperoxide-Induced Damage of Vascular Endothelial Cells / 中国药学杂志

OBJECTIVE: To explore the protective effect of Radix Rhapontici water extract (RRWE) on the damage of vascular endothelial cells induced by tert-butyl hydroperoxide (TBHP) in vitro. METHODS: The cellular model was established by treating human umbilical vein endothelial cells with TBHP, and randomly assigned to 4 groups:the control, TBHP, low and high-dose RRWE groups. Cell viability was tested by MTT assay, the levels of reduced glutathione (GSH), malondialdehyde (MDA), and superoxide dismutase (SOD) were measured by colorimetric method, the reactive oxygen species (ROS), apoptosis, and mitochondrial membrane potentials were observed by fluorescent staining, and the protein expressions of NF-κB, JNK, Bax, Bcl-2 and caspase-3 were determined with Western blotting method. RESULTS: Pretreatment with RRWE significantly increased the cell viabilities, reduced ROS levels, decreased MDA formation, increased the GSH contents and SOD activities, elevated the mitochondrial membrane potentials, down-regulated the p-JNK and p-NF-κB levels, reduced Bax/Bcl-2 ratios, suppressed caspase-3 activation, and inhibited cell apoptosis of vascular endothelial cells. CONCLUSION: RRWE has a protective effect on the damage of vascular endothelial cells induced by TBHP in vitro, and suppresses the cell apoptosis maybe through inhibiting JNK and NF-κB activation.

An analysis of four cases of misdiagnosed primary lymphocytic hypophysitis / 中华内科杂志

To improve the differential diagnosis of sellar region mass,4 cases with sellar mass and misdiagnosed as lymphocytic hypophysitis (LYH) were reviewed retrospectively.The 4 patients (2 male and 2 female) aged 20-60 years old were all presented with symptoms of headache,polydipsia and polyuria.Biochemical studies confirmed the diagnoses of central diabetes insipidus and hypopituitarism.Head MRI scans showed LYH like image for all the cases,and,thus,high dose methylprednisolone pulse therapy (HDMPT) was applied to the patients.Their symptoms deteriorated and the sellar mass enlarged after a short period of partial improvement.Operations were performed in all the patients.Histology study showed craniopharyngioma with abscess,primary abscess,secondary hypophysitis caused by Wegener's granulomatosis,and germinoma with secondary hypophysitis,respectively.In conclusion,surgery or biopsy is necessary for those who presented with sellar region mass and was suspected to be with LYH,but with poor response or even worse after HDMPT.

Effects of gender on screening value of aldosterone-renin ratio for primary aldosteronism / 解放军医学杂志

Objective To explore the potential influence of gender on screening value of aldosterone-renin ratio (ARR) for primary aldosteronism (PA).Methods The biochemical parameters were collected of 451 PA patients and 300 essential hypertension (EH) patients who were diagnosed in the General Hospital of PLA from 1992 to 2014. Each group was then divided into two groups by gender. The clinical characteristics were compared and then the receiver operating characteristic curve (ROC) was conducted to evaluate the best cut-off value.Results The plasma aldosterone concentration (PAC), serum sodium and ARR were much higher, but the plasma rennin activity (PRA), serum potassium and BMI were much lower in PA patients than in EH patients (P0.05). The best cut-off value of ARR in male PA patients was 19.11, the relevant area under the curve (AUC) was 0.968, the sensitivity and specicantcity was 92.44% and 93.08%, and the Youden index (YI) was 0.86. The best cut-off value of ARR in female PA patients was 27.26, with AUC 0.956, sensitivity 92.07%, specicantcity 90.00% and YI 0.82, respectively. If the cut-off value was set at 27.26 in males, the specicantcity would rise a little, but the sensitivity and YI would sharply decrease. Similarly, the sensitivity would increase a little but the specicantcity and YI would fall substantially if the cut-off value in females was set at 19.11. The best cut-off value of ARR in men was smaller than the ocantcial value recommended by guidelines.Conclusion Gender is an important factor should be considered while ARR is used in PA screening, and the cut-off value of ARR in screening female PA patients should be setting higher.

Characteristics of brain functional alterations and task functional magnetic resonance imaging in patients with Cushing's disease / 解放军医学杂志

Objective To analyze the relationship between the brain functional alterations of patients with Cushing's disease (CD) and patients' mental symptom by applying the Evaluating Emotional Scales and task functional magnetic resonance imaging (Task fMRI).Methods Task fMRI was performed on 8 patients with diagnosed CD admitted in the Department of Endocrinology of Chinese PLA General Hospital from Nov. 2015 to Nov. 2016 and 21 healthy people with matched age, gender and education level as control. Meanwhile, Self-Rating Depression Scale (SDS), Self-Rating Anxiety Scale (SAS), Positive and Negative Affective Scale (PANAS) and Cushing Quality of Life Scale (Cushing QOL) were obtained to assess the brain functions.Results Significant depression and anxiety were observed in patients with CD, and their positive affective score was substantially lower while the negative affective score was relatively higher compared with that in the controls. Task fMRI revealed that, when watching the positive pictures, the activation degree of left cerebellum and right postcentral gyrus weakened in CD patients than in the controls, and the positive correlations existed between the activation degree of left cerebellum and the 16 o'clock adrenocorticotrophic hormone (ACTH) level, and between the activation degree of right postcentral gyrus and the urinary free cortisol (UFC) level in CD patients. In contrast, when watching the negative pictures, the activation degree of left cerebellum, bilateral parahippocampal gyrus and left inferior frontal gyrus was weakened in CD patients than in the controls, and the activation degree of left cerebellum was negatively correlated to the 0 o'clock cortisol level and SAS score, but is positively correlated to the UFC level. When watching the neutral pictures, the activation degree of left cerebellum and left parahippocampal gyrus was weakened in CD patients than in the controls.Conclusions CD patients may have impaired brain function with depression and anxiety mental symptoms. By Task fMRI, it can be found that the weakened activation degree of left inferior frontal gyrus, right postcentral gyrus, bilateral parahippocampal gyrus and left cerebellum may be related to CD patients' mental symptoms.

A retrospective study on the clinical characteristics of patients with growth-hormone adenoma / 解放军医学杂志

Objective To evaluate the clinical characteristics of patients with growth-hormone adenoma (GHA) and summarize the diagnosis and treatment experience.Methods The clinical data of 338 GHA cases at the General Hospital of PLA from Jan. 1990 to Dec. 2016 were collected, of which 252 cases with more complete clinical data were retrospectively analyzed including their general situation, medical history, laboratory tests and auxiliary examinations, and treatment modalities and outcomes. Parts of the patients were followed up.Results The cases of hospitalized GHA patients have increased year by year since 1990, and the number of patients admitted in the last 3 years accounted for 56.2% of the total number of cases. The sex ratio for GHA patients was nearly 1:1. Age of visiting followed Gaussian distribution while the 41-50 age group occupied the largest part. The most typical sign is hand and foot enlargement (60.7%), followed by the hypertrophy of nasal ala. The most common symptoms are headache (42.5%), hypopsia, visual field defect and diplopia. More than half of GHA patients were complicated with prediabetes and diabetes (72.6%), sleep apnea (69.5%), goiter or thyroid nodularity (56.4%), cardiac insufficiency (57.0%) and colon polyp (54.1%); while the percentages of cases undergone the relevant examination in the total number of cases were as follows: 75g OGTT test (42.1%), polysomnography (23.4%), thyroid ultrasound (37.3%), echocardiogram (47.6%) and colonoscopy (14.7%); GHA was 23.37±1.42μg/L and IGF-1 was 804.28±273.93ng/ml on average; 85.0% of somatotroph tumors are macroadenoma. Surgery remains the mainstay of therapy to GHA, while medical therapy was selected by less patients. During the follow-up, only 38.0%of GHA patients can be contacted, among them the remission rate decreased to 40.5%. The positive rate of long-term remission evaluated by early postoperative GHA level was consistent with that confirmed by the long-term follow-up (χ2=3.368,P>0.05). Conclusions The number of hospitalized GHA patients have increased recent years. The common clinical signs and symptoms are somatic enlargement and nonspecific headache. Due to uncompleted screening, GHA associated complications are always misdiagnosed; It is essential to establish a sound model of follow-up to improve patients' quality of life. The early postoperative GHA levels may predict the prognosis of surgery.

A comparative study of the clinical features of thyrotropin-secreting pituitary adenomas / 解放军医学杂志

Objective To comparatively analyze the clinical characteristics of thyrotropin-secreting pituitary adenomas (TSH-omas).Methods The clinical features, laboratory variables, imaging and pathological Results were retrospectively compared and analyzed of 26 cases with TSH-omas admitted in Chinese PLA General Hospital from Feb. 2006 to Oct. 2016 and 20 cases with TSH-omas admitted in Shanghai Huashan Hospital from Apr. 2006 to Apr. 2013.Results The female ratio was slightly higher in patients of Chinese PLA General Hospital than in Huashan Hospital [(57.7%(15/26)vs. 45.0%(9/20)], while the mean age was similar [39.5±14.1(18-67 years)vs. 40.0±14.5(17-74 years)]. The most common chief complaint was thyrotoxicosis [73.1%(19/26)vs. 55.0%(11/20)], and mild-to-moderate goiter was the most common symptom. The mean serum TSH levels in Chinese PLA General Hospital and in Huashan Hospital were 5.06(2.97-6.27)mU/L and 6.16(3.76-10.91)mU/L respectively, and patients with normal serum TSH levels were more common in Chinese PLA General Hospital than in Huashan Hospital [57.7%(15/26)vs. 40.0%(8/20)]. Microadenoma was more common in Chinese PLA General Hospital than in Huashan Hospital [34.62%(9/26)vs. 20.0%(4/20)], while macroadenoma was more common in Huashan Hospital than in Chinese PLA General Hospital [20.0%(4/20)vs. 7.7%(2/26)]. Microadenoma was more common in female patients of the both groups [66.7%(6/9)vs. 75.0%(3/4)], while macroadenoma was all found in male patients. Tumor invasion of surrounding tissue and structure was often found in macroadenoma. In terms of octreotide inhibition test, the range of 24h TSH inhibition rate was roughly the same in the two groups (37.4%-91.8% and 46.5%-94.1%, respectively). Mixed adenoma was rare among all the pathologically confirmed cases. In Chinese PLA General Hospitals, TSH immunoreactive negative neoplastic cells were found in 3 of 8 cases, and octreotide scanning showed negative in 2 of 12 cases.Conclusions Patients with TSH-omas in the two hospitals show similarities but also some significant differences in the clinical features. Overall, the domestic patients with TSH-omas are diagnosed without gender difference according to the reports in China. The mean age at diagnosis is significantly younger than that in foreign data. Microadenoma is more common in females, while macroadenoma is more common in males. Serum TSH levels can be normal in patients with TSH-omas. Immunostaining and/or octreotide scanning for TSH can be negative.

History, current situation and trend of China's overseas health facilities aid / 中国卫生政策研究

This study conservatively estimates that the Chinese government invests about 267millions USD per year on health facilities aid,almost reaching the amount of Germany,and ranked fifth globally.Health facilities built by China mostly are general hospitals and health care centers located in Arica with unified model and standards,and are the "Turn Key" projects.These facilities have helped to alleviate the scarcity of medical and health resources and accessibility of residents to health services to some extent,as well as promoting the employment and the living standards of local people.However,due to the lack of guidance and coordination of the overall strategic planning and harmonization of health aid efforts,and the knowledge of partner countries' health systems,emphasis on demand driven and feasibility of infrastructure construction while ignoring the needs assessment and feasibility of functional fulfillment,it's hard to achieve the targeted assistance in China's health facilities aid projects.It was found that it's necessary to make three changes in the future:from "infrastructure assistance" to "functional assistance";from "'project assistance" to "program assistance";from a single government official assistance to a combination of official assistance and investment.
