Objective To investigate the relationship between fatty liver progress and metabolic changes.Methods A total of 414 patients who had B-mode ultrasonography confirmed fatty liver development during 2 health check-ups within 2 years were enrolled in this study.Paired t and χ2 tests were used to compare body mass index (BMI),alanine aminotransferase (ALT),aspartate aminotransferase (AST),fasting plasma glucose (FPG),serum uric acid (UA),triglycerides (TG),and high-density lipoprotein cholesterol (HDL-C) among the participants.Results BMI,TG,HDL-C,ALT,AST,and UA were significantly increased after fatty liver progressed,although HDL-C was largely decreased.ConclusionsPrevention and treatment of MS as well as early intervention for fatty liver should be important for successful control of fatty liver.

Objective To find the syndrome tendency of fatty liver people and then providing basis for TCM integrated into fatty liver patients'Health Management by analyzing the characteristics of fatty liver people's tongue and combining them with the investigating results of symptoms.Methods Using 1∶1control study methods,examined 368 cases(184 cases were patients with fatty liver),observed their tongues as well as their symptoms,and recorded results.Results x2 test showed fat tongue,thin and small tongue,teeth-marked tongue,thick fur,greasy fur,fond of cool drink,hate feat,diarrhea after eating cold food,more sweat,lethargy,heavy four limbs,more flatus were significantly increase in fatty liver people(x27·580,11.740,23.700,8.666,10.793,P>0.05).Conclusions The symptoms of patients with fatty liver disease were the reflection of heat and(or)damp-heat.Found the generally pathology rules of patients with fatty liver disease,we could be more reasonable and effective prevention and treatment.

Objective To study the metabolic parameters in health checkup people with dark red tongue and light red tongue,with different coating nature,coating color or liguliform,to understand the relationship between dark red tongue and human metabolic state.Methods Clinical data of 2 891 individuals who underwent health checkup in our center between Dec.2013 and Aug.2014 were collected,including body mass index,blood pressure,blood glucose,lipid and uric acid.Tongue diagnosis was made by Chinese Medicine practitioners.Results The dark red tongue was more common in males,it was found in 61.58％ males and 38.42％ females in the dark red tongue group.The average level including body mass index,systolic blood pressure,diastolic blood pressure,blood glucose,total cholesterol,triglyceride,low-density lipoprotein cholesterol and blood uric acid in dark red tongue group were higher than those in light red tongue group (P＜0.01).When the dark red tongue had yellow fur-like or thick and greasy coat,the average level of body mass index,blood glucose,total cholesterol,low-density lipoprotein cholesterol and blood uric acid were higher than those of the normal dark red tongue group,the level of high-density lipoprotein cholesterol was lower than that of the normal dark red tongue group.Conclusions Dark red tongue has homogeneous relations with abnormal metabolic parameters,it may be the external expression of metabolic abnormalities;tongue is the external macro manifestation of human body health state.

Objective To evaluate the effects of nurse-led team management on self-management and hyperten-sion control for community-dwelling hypertensive patients. Methods A quasi-experimental study design was adopt-ed,two communities were elected as the intervention group and the control group in Wuhou District,Chengdu,and 102 hypertensive patients were recruited from each group. The intervention group received nurse-led team manage-ment for 2 years,and intervention methods included individual management,phone or home follow-up,collective inter-vention and so on. While the control group received doctor-led hypertension management. The patients' self-man-agement behaviors and hypertension control were evaluated before the intervention and 6,12,24 months after the intervention. Results After 24-month nurse-led team management,scores of self-management behaviors and hyper-tension control rate of patients in the intervention group were significantly higher than those of patients in the con-trol group(P<0.05). Conclusion Nurse-led team management could significantly improve self-management behaviors and the rate of hypertension control for hypertensive patients.

Objective To investigate the compound donkey-hide gelatin syrup in reducing adverse reactions of qi-blood weakness patients caused by clozapine.Methods 132 patients from Psychiatric Hospital of Yunnan Province between January 2010 and June 2010 were randomly divided into a treatment group and a control group.Both groups were taken clozapine orally.On this basis,the treatment group was taken compound donkey-hide gelatin syrup and the control group was taken placebo syrup.After 8 weeks treatment for both groups,the PANSS,TESS,physical examination and experiment examination were observed to evaluate the clinical efficacy and safety.Results ① the total curative effect:the treatment group was 73.53％,the control group was 65.63％,showing statistical difference (x2=2.543,P＜0.05).② PANSS scores changes before and after the treatment:PANSS score at 2,4,6,8 weeks after the treatment of both groups were [(72.51 ±27.55),(60.54±24.03),(53.12± 15.27),(48.15± 11.88) in treatment group respectively,and (70.71 ±23.90),(58.89± 18.95),(53.06± 14.38),(48.98 ± 9.78) in the control group,respectively],both showing significant difference than the same group before the treatment [(103.99±39.12) in the treatment group,(99.78±34.35) in the control group] (P＜0.05).But there was no statistical significance between two groups (F=2.413,P＞0.05).③ adverse reactions:during the treatment liver function,blood cell analysis,dystonia,Parkinson's obstacle,akathisia,abnormal gastrointestinal reaction,heart rate,heart rate variability and blood pressure in the treatment group was significantly lower than the control group (x2=4.562,P＜0.05).Conclusion Compound donkey-hide gelatin syrup can effectively relieve adverse reactions in qi-blood weak psychosis patients after clozapine treatment and improve their drug tolerance.

A method for simultaneous determination of PCDDs, dl-PCBs, BFRs and PBDD/Fs in flue gas from stationary source was developed. The sample was extracted by Soxhlet apparatus with toluene, and followed by purification through sulfuric acid partition and multi-layer silica gel column separation. The target compounds were then all separated by passing through the active carbon-dispersed silica gel column and reversal eluting. Gas chromatography coupled with a thermostable capillary column ( short length, thin stationary phase film) was operated at pulse injection mode. High resolution mass spectrometry set at low-electron-energy ionization was used for quantification. The high- and low-brominated compounds were determined simultaneously. The detection limits of this method were 0. 081-1. 2 pg for PCDD/Fs, 0. 10-0. 32 pg for dl-PCBs, 0. 14-12 pg for PBDEs, 0. 26-16 pg for new BFRs, 0. 44-3. 6 pg for tetra- to hepta-BDD/Fs and 8. 2-12 pg for OBDD/F. Recoveries ( RSDs) in spiked flue gas samples were 88%-115%(2. 9%-6. 1%) for PCDD/Fs, 84%-118% (3. 2%-10%) for dl-PCBs, 71%-135% (2. 1%-18%) for PBDEs, 71%-114% (2. 9%-7. 4%) for new BFRs, 83%-127% (5. 2%-10%) for tetra-to hepta-BDD/Fs and 52%-149% ( 23%-24%) for OBDD/F. All quality control data fell within the acceptable range specified in analysis standards for flue gas.

Mild encephalitis/encephalopathy with reversible splenial lesion has special clinical-imaging features. According to the extent of lesion involvement, it can be divided into type Ⅰ and type Ⅱ. Clinically, type Ⅰ is more common, and type Ⅱ is rare. A rare case of recurrent type Ⅱ mild encephalitis/encephalopathy with reversible splenial lesion is reported. The patient presented with typical type Ⅱ mild encephalitis/encephalopathy with reversible splenial lesion for the first time, involving the corpus callosum and the deep white matter, and the lesions disappeared after a short-term reexamination. Two years later, the lesions recurred, and the scope of the lesions was similar to that of the first time, and the lesions disappeared after a short-term reexamination. The clinical and imaging findings are analyzed in combination with relevant literatures review in order to deepen the understanding of the disease and improve the level of diagnosis and treatment.

Objective To investigate the morphological differences of proximal femoral medullary cavity in elderly patients with intertrochanteric fracture and its effect on the treatment efficacy of proximal femoral nail antirotation (PFNA). Methods A retrospective case series study was conducted on the clinical data of 112 elderly patients with intertrochanteric fracture of the femur from December 2012 to January 2017, including the preoperative and postoperative hip joints orthotopic X ray (including the proximal femur), lateral X ray, and pelvic orthotopic X ray films. The proximal femoral canal flare index (CFI) and the metaphyseal canal flare index (MCFI) were measured. The proportion of patients with different types of medullary cavity and the gender difference were analyzed according to Dorr typing. The fractures were classified according to the modified Evans classification. Operation time, fracture reduction quality, tip apex distance (TAD), incidence of intraoperative split fracture around the rotors, postoperative fracture reduction loss rate, weight bearing time, and fracture healing time were recorded. Results The proximal femoral canal flare index (CFI) was significantly correlated with the intramedullary diameter above the lesser trochanter, the inner diameter of the affected side medullary cavity isthmus, and metaphyseal canal flare index (MCFI) (P ＜0.01). There was clear difference in gender in terms of the medullary cavity diameter 20 mm above the middle point of lesser trochanter, medullary isthmus internal diameter, the medullary cavity diameter 20 mm below the middle point of lesser trochanter, CFI, and MCFI. Thereinto, there was significant difference in the medullary cavity diameter 20 mm above the middle point of lesser trochanter [male (52.6 ± 6.4) mm, female: (49.9 ± 5.4) mm], the medullary cavity diameter 20 mm below the middle point of lesser trochanter [male: (26.5 ± 3.7) mm, female: (23.1 ±2.8)mm], and MCFI (male:2.0 ±0.3, female:2.2 ±0.2). No significant difference between the medullary isthmus internal diameter and CFI was found (P＞0.05). In this group, the medullary cavity of proximal femur was classified by Dorr: the proportion of funnel type, normal type, and chimney type was 5.4％ (6/112), 73.2％ (82/112), and 21.4％ (24/112), respectively. There was no significant difference in the modified Evans fracture stability among different morphological types of the proximal femoral medullary cavity. The difference of weight bearing time between normal group and chimney group was statistically significant [normal type: (21.4±16.9)d, chimney type: (45.5 ± 11.2)d] (P ＜ 0.05), but there were no significant differences in operation time, reduction quality, TAD, intraoperative incidence of cleavage fracture incidence, reduction loss rate, and healing time between the two groups (P＞0.05). Conclusions The occurrence and development of osteoporosis can cause significant changes in the morphology of proximal femoral medullary cavity, mainly manifesting as the gradual increase of the proportion of chimney type. The efficacy of PFNA in treatment of the intertrochanteric fracture is satisfactory. However, the risk of intraoperative cleavage fracture and postoperative reduction loss should be taken seriously.

Objective To investigate the prevalence and risk factors of diabetic retinopathy (DR) in a Beijing population during routine medical examinations. Methods This was a cross-sectional study during a routine health examination at the Tongren Hospital of Beijing,from March 2014 to February 2015. Fundus photography was conducted by experienced ophthalmologists.Medical history,height,weight,waist and hip circumference,and blood pressure were recorded.Routine laboratory examinations were performed. Logistic regression models were used to estimate the odds ratio (OR) and 95% confidence interval (CI) of diabetic retinopathy for each risk factor,adjusted for age and gender. Results The prevalence of DR was 7.0% among diabetic individuals.The multivariate analysis showed that disease durations[OR(95% CI),2.1 (1.564-2.752),P<0.001],fasting plasma glucose[1.2(1.093-1.273),P<0.001],body mass index[1.8(1.010-3.100),P=0.046],and triglyceride[0.794(0.638-0.987),P=0.038]were independently associated with DR. The prevalence of diabetes mellitus (DM) and DR significantly increased in populations aged>30 years. Conclusion Fundus photography (nonmydriatic) should be recommended as a routine screening method for people 30 years and elder to effectively prevent occurrence of visual impairment and blindness.

Objective:To investigate the prevalence and risk factors of hypertensive retinopathy (HRP) in a non-diabetic population over 30 years old during routine health examinations.Methods:This was a cross-sectional study of a non-diabetic population over 30 years of age. The study was conducted during routine health examinations at the Tongren Hospital, Beijing, from January to December 2020. Fundus photographs were taken, and data including medical history, height, weight, and blood pressure were collected. Routine laboratory examinations were performed. The study population was divided into hypertension, transient hypertension, and non-hypertension groups. The prevalence of HRP was compared among the three groups. OR and 95% CI of HRP risk factors was estimated by binary logistic regression, adjusted for age and gender. Results:The prevalence of HRP was 4.3% in the non-diabetic population over 30 years old. Adjusted for age, gender, and systolic blood pressure, the prevalence of HRP in hypertension and transient hypertension groups, was both higher than in the non-hypertension group [ OR(95% CI) of 3.11(2.25-4.30) and 1.72(1.21-2.45), respectively]. The proportion of grade 1-2 HRP was higher (76.2%). There was no significant difference in the prevalence of grade 3 HRP among the three groups. Adjusted for age and gender, systolic blood pressure and creatinine clearance rate were independent risk factors for HRP in the hypertension group [ OR(95% CI): 1.22(1.01-1.48) and 1.66(1.12-2.46)] and transient hypertension group [ OR(95% CI): 1.48(1.10-2.06) and 1.95(1.03-3.46)]. SBP and DBP were independent risk factors for HRP in the non-hypertension group [ OR(95% CI): 1.68(1.07-2.63) and 1.61(1.06-2.44)]. Conclusions:There was a high prevalence of HRP among the non-diabetic population over the age of 30 and there was still relatively high risk of grade 3 HRP among the normotensive population.
