Objective:To propose a Chinese diagnostic criterion for rosacea on the basis of clinical feature analysis of rosacea, and to assess its sensitivity and specificity.Methods:A total of 3 350 Chinese patients with newly diagnosed rosacea were collected from Department of Dermatology, Xiangya Hospital, Central South University between December 2017 and July 2018, their phenotypes and clinical features were retrospectively analyzed, and a Chinese modified diagnostic criterion for rosacea was put forward. A national multi-center clinical observational trial, which included 2 269 patients with rosacea and 2 408 patients with other facial skin diseases from 28 centers, was conducted to verify this diagnostic criterion. Then, the sensitivity and specificity of the modified diagnostic criterion were evaluated by comparing with the 2017 standard classification of rosacea developed by the National Rosacea Society Expert Committee (NRSEC) .Results:Fixed centrofacial erythema occurred in 3 350 (100%) patients with rosacea. Flushing occurred before or simultaneously with fixed erythema in 1 850 (99.4%) of the 1 861 patients with erythema on the cheeks; among the 1 489 patients with erythema on the nose or perioral area, only 52 (3.5%) had flushing; all the 342 patients presenting with phymatous changes had fixed erythema before phymatous changes. Based on the above clinical findings, it was proposed that patients with periodically aggravated fixed erythema on the cheeks accompanied with flushing could be diagnosed with rosacea; patients with fixed erythema on the nose and perioral area accompanied with at least one of selective phenotypes (flushing, telangiectasia, papules and pustules, phymatous changes, or ocular manifestations) could be diagnosed with rosacea. The national multi-center clinical observational trial revealed that the sensitivity of the Chinese modified diagnostic criterion for rosacea was 99.6%, which was close to the sensitivity (100%) of the NRSEC standard, and its specificity was 91.9%, higher than the specificity (73.3%) of the NRSEC standard.Conclusion:The Chinese modified diagnostic criterion for rosacea has good sensitivity and specificity, and can facilitate the early diagnosis of phymatous rosacea.

Enzyme-linked immunosorbent assay(ELISA) and metabolomics were used to analyze and compare two animal models of heart-kidney insomnia, in order to explore a more ideal animal model and preliminarily explore the essence of heart-kidney insomnia. Based on the clinical symptoms and disease characteristics of heart-kidney insomnia, the animal model of heart-kidney insomnia was reproduced through intraperitoneal injection with p-chlorophenylalanine(PCPA) and multi-factor interaction. The animal model of disease-syndrome combination was evaluated by behavioral observation, ELISA and metabolomics. Wistar rats were randomly divided into normal group, PCPA group and compound model group(FH). The rats' behavior, body weight, adrenal index and spleen index were recorded. The levels of corticotropin releasing hormone(CRH) and adrenocorticotropin(ACTH) in serum were detected by ELISA, and the differential metabolites in serum were detected by UPLC-QE-MS. The body weight and adrenal index in FH group were significantly lower than those in PCPA group(P<0.05); whereas ACTH and CRH in FH group were significantly higher than those in PCPA group by ELISA; nine potential biomarkers were identified by serum sample statistics. There were four main metabolic pathways in cardiorenal insomnia: pentose phosphate metabolism, alanine, aspartic acid and glutamic acid metabolism, histidine metabolism, and taurine and subtaurine metabolism. PCPA and multi-factor interaction method can successfully replicate the insomnia model, but multi-factor modeling method is more similar to clinical traditional Chinese medicine syndrome. Animal behavior, ELISA and metabolomics were used to evaluate the rat model of cardiorenal insomnia from in vitro to in vivo, from macro to micro, and from individual to the whole.

Objective To explore the structure changes of white matter of the patients with schizophrenia episode in early adulthood by diffusion tensor imaging(DTI) and in order to provide a structural neuroimaging basis for understanding the pathology of schizophrenia.Methods Twenty-six patients with schizophrenia episode in early adulthood in the Second Affiliated Hospital of Xinxiang Medical University from July 2012 to March 2014 were selected as study group and twenty-eight healthy subjects whose age,sex,education were matched with study group were selected as control group.All subjects received structural magnetic resonance imaging and DTI scans.The fractional anisotropy (FA) and the mean diffusivity (MD) of the white matter of the same encephalic region were compared between the two groups by voxel-based analyses.Results The FA values of the right anterior cingulate gyrusthe,genu of corpus callosum,the right limb of internal capsule,the bilateral external capsule,the bilateral posterior of coronal radiate,the right anterior coronal radiate of patients in the study group were significantly lower than those in the control group (P ＜ 0.05).The MD values of the bilateral limbs of internal capsule,the right cingulate gyrus,left superior longitudinal tract,corpus callosum and right anterior coronal radiate of patients in the study group were significantly higher than those in the control group (P ＜ 0.05).Conclusion Schizophrenia patients who episode in early adulthood exist widespread microstructural damage of white matter.These changes may be related to the pathological change of schizophrenia.

Background: Right upper lobectomy (RUL) for lung cancer with different dissecting orders involves the most vari-able anatomical structures, but no studies have analyzed its effects on postoperative recovery. This study compared the conventional surgical approach, VAB (dissecting pulmonary vessels first, followed by the bronchus), and the alter-native surgical approach, aBVA (dissecting the posterior ascending arterial branch first, followed by the bronchus and vessels) on improving surgical feasibility and postoperative recovery for lung cancer patients. Methods: According to the surgical approach, consecutive lung cancer patients undergoing RUL were grouped into aBVA and VAB cohorts. Their clinical, pathologic, and perioperative characteristics were collected to compare periop-erative outcomes. Results: Three hundred one patients were selected (109 in the aBVA cohort and 192 in the VAB cohort). The mean operation time was shorter in the aBVA cohort than in the VAB cohort (164 vs. 221 min, P < 0.001), and less blood loss occurred in the aBVA cohort (92 vs. 141 mL, P < 0.001). The rate of conversion to thoracotomy was lower in the aBVA cohort than in the VAB cohort (0% vs. 11.5%, P < 0.001). The mean duration of postoperative chest drainage was shorter in the aBVA cohort than in the VAB cohort (3.6 vs. 4.5 days, P = 0.001). The rates of postoperative complica-tions were comparable (P = 0.629). The median overall survival was not arrived in both cohorts (P > 0.05). The median disease-free survival was comparable for all patients in the two cohorts (not arrived vs. 41.97 months) and for patients with disease recurrences (13.25 vs. 9.44 months) (both P > 0.05). The recurrence models in two cohorts were also comparable for patients with local recurrences (6.4% vs. 7.8%), distant metastases (10.1% vs. 8.3%), and both (1.8% vs. 1.6%) (all P > 0.05). Conclusions: Dissecting the right upper bronchus before turning over the lobe repeatedly and dissecting veins via the aBVA approach during RUL would promote surgical feasibility and achieve comparable postoperative recovery for lung cancer patients.

BACKGROUNDNontraumatic osteonecrosis of the femoral head (NONFH) is a debilitating disease that represents a significant financial burden for both individuals and healthcare systems. Despite its significance, however, its prevalence in the Chinese general population remains unknown. This study aimed to investigate the prevalence of NONFH and its associated risk factors in the Chinese population.

METHODSA nationally representative survey of 30,030 respondents was undertaken from June 2012 to August 2013. All participants underwent a questionnaire investigation, physical examination of hip, and bilateral hip joint X-ray and/or magnetic resonance imaging examination. Blood samples were taken after overnight fasting to test serum total cholesterol, triglyceride, and high-density lipoprotein (HDL) and low-density lipoprotein (LDL) levels. We then used multivariate logistic regression analysis to investigate the associations between various metabolic, demographic, and lifestyle-related variables and NONFH.

RESULTSNONFH was diagnosed in 218 subjects (0.725%) and the estimated NONFH cases were 8.12 million among Chinese people aged 15 years and over. The prevalence of NONFH was significantly higher in males than in females (1.02% vs. 0.51%, χ2 = 24.997, P < 0.001). Among NONFH patients, North residents were subjected to higher prevalence of NONFH than that of South residents (0.85% vs. 0.61%, χ 2 = 5.847, P = 0.016). Our multivariate regression analysis showed that high blood levels of triglycerides, total cholesterol, LDL-cholesterol, and non-HDL-cholesterol, male, urban residence, family history of osteonecrosis of the femoral head, heavy smoking, alcohol abuse and glucocorticoid intake, overweight, and obesity were all significantly associated with an increased risk of NONFH.

CONCLUSIONSOur findings highlight that NONFH is a significant public health challenge in China and underscore the need for policy measures on the national level. Furthermore, NONFH shares a number of risk factors with atherosclerosis.
