OBJECTIVE: To investigate the allergens distribution of 576 allergic rhinitis patients in Qingyang, and to provide basic epidemiologic information for the prevention and treatment of allergic rhinitis. METHOD: Skin prick test was done to all the 576 patients with allergic rhinitis with 28 kinds of allergens. RESULT: Four hundred and eighty cases (83.3%) showed positive reaction to at least one allergen of 28 allergens. The most common allergens were Magwort (73.3%), Giant Ragweed (55.0%) Tree II (51.7%), Tree I (48.3%) Dermatophagoides farinae (43.3%) and Dermatophagoides pteronyssinus (36.7%). Moreover. the positivity decreased with age. There was no difference between male and female. CONCLUSION The study shows that Magwort. Giant ragweed and tree II are the most important allergens on Qingyang district.

Objective:To assess the changes of cardiac output (CO)-related indices in healthy term reproductive age pregnant women during labor.Methods:A prospective longitudinal study was conducted, involving 208 pregnant women at term who were at an reproductive age and admitted to the labor ward of Tianjin Central Hospital of Obstetrics and Gynecology from October 2020 to March 2021. The internal diameter of the aortic root, velocity-time integral of aortic valve flow, and heart rate were obtained through transthoracic echocardiography during uterine contractions period and the intervals between contractions in the latent phase, active phase, and the second stage of labor, as well as at one hour after delivery. Stroke volume (SV), CO, and cardiac index (CI) were then calculated. Comparisons among groups were performed using t-test, analysis of variance, or Wilcoxon test. CO-related indices during contractions periods and intervals between contractions were compared using paired t-test, those in each stage of labor using repeated measurement analysis of variance. Results:(1) CO-related indices in contractions periods vs intervals between contractions during labor: In the latent phase, maternal heart rate [79(72 -84) vs 76(70 -85) bpm, Z=－2.03, P<0.05], SV [(77.9±13.4) vs (71.1±12.8) ml, t=－13.98, P<0.05], CO [(6.1 ±1.2) vs (5.5 ±1.1) L/min, t=－14.19, P<0.05], and CI [(3.5 ±0.7) vs (3.1 ±0.6) L/(min·m 2), t=－14.29, P<0.05] during contractions were higher than those during the intervals. These parameters during contractions in the active phase and the second stage of labor were all higher than those during the intervals in the same stage (all P<0.05). (2) CO-related indices in each period of labor: Heart rate, CO, and CI during the intervals between contractions gradually increased along with labor progression and reached the peak at the second stage followed by a decrease at one hour after delivery, and a similar trend was also observed for these parameters during contractions in the whole labor (all P<0.05). No significant changes in the maternal SV during intervals between contractions were observed during the labor( P=0.366), while the figure during contractions showed a decreased trend along with the course of labor and declined to a nadir in the second stage (all P<0.05). Conclusions:Cardiac output related indices change significantly in healthy term reproductive age pregnant women during labor, especially in the second stage of labor. Therefore, correct monitoring and management of hemodynamic changes during labor are of great importance in the stability of cardiovascular function throughout labor.

Based on the research of current domestic medical service item and the financial classification policy,combined with the existing problem during the practice,it analyzes the existing problem of financial classification in medical service item cost,and discusses the proposal of nationwide unified mapping between medical service item and their financial classification,the practice path-way of implementation,it can be the valuable reference for hospital's refined financial management and payment reform.

Objective:To investigate the detection rate and related factors of thyroid nodules in people with abnormal lipid metabolism.Methods:From September 4, 2016 to February 1, 2017, community residents living in Lanzhou City, Longnan City, Dingxi City and Linxia City of Gansu Province for more than 5 years were selected as the respondents. General data were recorded, venous blood was collected, blood lipid related biochemical indexes were detected, and thyroid ultrasound was performed. By comparing the general data and biochemical indexes, the detection of abnormal lipid metabolism and thyroid nodules were analyzed, and the risk factors of thyroid nodules in people with abnormal lipid metabolism were analyzed by logistic regression.Results:Two thousand and fifty-nine residents were included in this study (1 049 males and 1 010 females). The total detection rate of thyroid nodules was 23.17% (477/2 059). The detection rate of thyroid nodules in people with abnormal lipid metabolism [34.16%(151/442)] was significantly higher than that in people with normal lipid metabolism [20.16% (326/1 617) , P < 0.01], and the detection rate of thyroid nodules of women [43.37% (85/196) ] was higher than that of men [26.83% (66/246) , P < 0.01]. Among the people with abnormal lipid metabolism, the highest detection rate of thyroid nodules was in mixed hyperlipidemia [57.14% (16/28)], followed by hypertriglyceridemia [34.59% (92/266)]. The detection rates of thyroid nodules in the groups with elevated total cholesterol (TC) and low density lipoprotein cholesterol (LDL-C) levels [35.16% (32/91), 34.85% (23/66)] were higher than those in the marginal elevated group [27.04%(86/318), 30.42% (73/240)] and the normal groups [21.76% (359/1 650), 21.73% (381/1 753), P < 0.05]. The results of logistic regression analysis showed that the risk factors of thyroid nodules in people with abnormal lipid metabolism were increased age, elevated fasting blood glucose (FPG), elevated blood glucose 2 hours (2 h PG) after oral glucose tolerance test (OGTT) load and elevated glycosylated hemoglobin [HbA1c, odds ratio ( OR)=1.065, 1.387, 1.866, 1.384, P < 0.05]. Conclusions:The prevalence of TN is higher in populations with abnormal lipid metabolism. The control of blood sugar and blood lipid levels may play a role in the prevention of thyroid nodules.

OBJECTIVE: To evaluate the efficacy of internal fixation of lateral and medial borders for displaced scapular body fractures via the minimally invasive approach. METHODS: The internal fixation of lateral and medial borders via minimally invasive approach was applied in surgical treatment of 23 patients with scapular body comminuted fractures from January 2014 to June 2018. The lateral approach was made straightly orienting over the lateral border of scapula. The dissection was taken down to the deltoid fascia. The deltoid was retracted cephalically, revealing the external rotators. Blunt dissection was used down to the lateral border between infraspinatus and teres minor, exposing the fracture site. The medial incision was done along the medial border of the scapula over site of the fracture. Dissections were taken down to the fascia and the periosteum. A subperiosteal dissection was then performed to elevate the infraspinatus to the degree necessary to visualize the fracture. The medial and lateral borders of scapula body were fixed with plates and screws in a frame-like way. RESULTS One patient developed the delayed healing of the incisions due to liquefactive fat necrosis. The other 22 patients showed no complications of the incisions. The glenopolar angle (GPA) of fractured scapula was increased from preoperative (25±12) degrees to postoperative (41±5) degrees (P<0.01). The healing time of fractures healed was 3-8 months, with an average time of (4.4±1.3) months. CONCLUSIONS The lateral-medial combined fixation through minimally invasive surgical approach for the scapula body fractures allows visualization of fracture reduction without extensive muscular or subcutaneous flaps, and is associated with successful fracture healing and high functional scores of the shoulder.
