Objective To study serum levels of soluble intercellular adhesion molecule-1 (sICAM-1) and its correlation with accumulation degree of 99Tcm-MDP on bone and arthritis and to study the role of sICAM-1 in the diagnosis of patients with early RA. Methods Serum levels of sICAM-1 were measured by immunoenzymetic assay (ELISA). 99mTc-MDP scintigraphy was carried out for the same patients. The significant test between serum levels of sICAM-1 of three groups was performed with analysis of variance; Correlations between serum levels of sICAM-1 and index of semiquatitive 99Tcm-MDP were obtained using sperman's ranks correlation method. Results Compared with control group,serum levels of sICAM-1 were significantly higher in standard group (group A) (P<0.01) and non-standard group (group B) (P<0.05). No significant difference was found between group A and B(P>0.05). Serum levels of sICAM-1 were positively correlated with 99Tcm-MDP scintigraphy. Most patients of non-standard group and standard group showed visible medium-high uptake of 99Tcm-MDP. While control group had not obviously uptake of 99Tcm-MDP. Conclusion Serum levels of sICAM-1, semiquatitive 99Tcm-MDP scintigraphy, accumulation degree of radiopharmuceuutial on bone and arthritis are helpful for diagnosis of early rheumatoid arthritis and judge-ment of the clinical status and improvement of the prognosis.

Objective: To study on the difference of serum iron(Fe) levels between normal healthy people and patients with AD in order to explore the effect of serum iron level on the phenotypical division of AD patients and discuss its influence and significance in the diet nursing of AD patients. Methods: A total of 30 patients with AD in Guangzhou Huiai Hospital were selected as the "AD group" from June 2014 to August 2017, and 30 healthy people in the corresponding health center of Guangzhou Huiai Hospital were selected as "the health control group". Data of general information, serum iron and red blood cell(RBC) index were collected in these two groups. General statistical analysis and cluster analysis were made based on the data. Results: RBC in healthy control group and AD group were 4.60(4.38,5.00)×10¹²/L and (4.32±0.51)×10¹²/L. Compared with the healthy control group, RBC in the AD group was lower and the difference was statistically significant (Z=2.493, P<0.05). But, the other indexes were not significantly different (P>0.05). There was no significant difference in the in Fe level, RBC, hemoglobin and other indexes in AD patients with the different severity of dementia (P>0.05). Based on the level of Fe and RBC, the 60 cases can be divided into four types of different characteristics.The Fe of four types were (12.39±2.35) , (13.55±2.07) ,[20.70(19.55,23.15)], [19.70(17.70,22.60)] μmol/L, the RBC were (4.07±0.30), [4.83(4.62,5.12)], [4.40(4.14,4.45)], [5.00(4.80,5.34)]×10¹²/L. The HGB were (125.30±8.74), (138.08±11.1), [136.00(127.00,139.00)], (151.91±13.49)g/L.The incidence of four types of AD, Fe level, RBC and hemoglobin content were different (t/Z/χ²=0.019-6.942, P<0.05). Conclusions Based on Fe and RBC, the population can be divided into 4 types. "Low Fe and low RBC"Type, "High Fe and high RBC"Type, "Low Fe and high RBC"Type and"High Fe and low RBC"."Low Fe and low RBC"Type contains most AD patients while "High Fe and high RBC"Type contains the least. There are close in the distribution of objects between"Low Fe and high RBC" and "High Fe and low RBC". According to the characteristics of these four types, different dietary care programs may be required

Objective To investigate the morbidity, diagnostic profile and perinatal outcome of pregestational diabetes mellitus (PGDM) in 15 hospitals in Guangdong province. Methods A total of 41338 women delivered in the 15 hospitals during the 6 months,195 women with PGDM(PGDM group) and 195 women with normal glucose test result(control group)were recruited from these tertiary hospitals in Guangdong province from January 2016 to June 2016. The morbidity and diagnostic profile of PGDM were analyzed. The complications during pregnancy and perinatal outcomes were compared between the two groups. In the PGDM group, pregnancy outcomes were analyzed in women who used insulin treatment (n=91) and women who did not (n=104). Results (1)The incidence of PGDM was 0.472%(195/41338). Diabetes mellitus were diagnosed in 59 women (30.3%, 59/195) before pregnancy, and 136 women (69.7%,136/195) were diagnosed as PGDM after conceptions. Forty-six women (33.8%) were diagnosed by fasting glucose and glycohemoglobin (HbA1c) screening. (2) The maternal age, pre-pregnancy body mass index (BMI), prenatal BMI, percentage of family history of diabetes, incidence of macrosomia, concentration of low density lipoprotein were significantly higher in PGDM group than those in control group (all P<0.05). Women in PGDM group had significantly higher HbA1c concentration((6.3±1.3)% vs (5.2±0.4)%), fasting glucose [(6.3±2.3) vs (4.8±1.1) mmol/L], oral glucose tolerance test(OGTT)-1 h glucose((12.6±2.9) vs (7.1± 1.3) mmol/L)and OGTT-2 h glucose [(12.0±3.0) vs (6.4±1.0) mmol/L] than those in control group (P<0.01). (3)The morbidity of preterm births was significantly higher (11.3% vs 1.0%, P<0.01), and the gestational age at delivery in PGDM group was significantly smaller [(37.6±2.3) vs (39.2±1.2) weeks, P<0.01]. Cesarean delivery rate in the PGDM group (70.8% vs 29.7%) was significantly higher than the control group (P<0.01). There was significantly difference between PGDM group and control in the neonatal male/female ratio (98/97 vs 111/84, P=0.033). The neonatal birth weight in PGDM group was significantly higher((3159±700) vs (3451±423) g, P<0.01). And the incidence of neonatal hypoglycemia in the PGDM group was higher than the control group (7.7% vs 2.6%, P=0.036).(4)In the PGDM group, women who were treated with insulin had a smaller gestational age at delivery [(36.9±2.9) vs (37.9±2.5) weeks, P<0.01], and the neonates had a higher neonatal ICU(NICU)admission rate (24.2% vs 9.6% , P<0.01). Conclusions The morbidity of PGDM in the 15 hospitals in Guangdong province is 0.472%. The majority of PGDM was diagnosed during pregnancy; HbA1c and fasting glucose are reliable parameters for PGDM screening. Women with PGDM have obvious family history of diabetes and repeated pregnancy may accelerate the process of diabetes mellitus. Women with PGDM have higher risk for preterm delivery and neonatal hypoglycemia. Unsatisfied glucose control followed by insulin treatment may increase the need for NICU admission.

Objective To grasp the prevalence of drinking brick-tea type fluorosis in Tibet,and to provide scientific basis for the development of prevention and control strategies.Methods Twelve counties were selected from 7 regions in Tibet.In accordance with the "Drinking Brick-Tea Type Endemic Fluorosis Monitoring Program",a total of 46 administrative villages were selected as survey points using the cluster stratified sampling method.Household water samples,tea-water samples and adult urine samples were collected,and household fluorine intake status and incidence of skeletal fluorosis in adults over 16 years old were investigated.In the rural grade primary school where the village children were concentrated,all children aged 8-12 were selected,urine samples were collected,and the prevalence of dental fluorosis was investigated.Fluoride contents in tea,water,and urine were detected by ion selective electrode method.The dental fluorosis and skeletal fluorosis were examined and judged according to the "Diagnosis of Dental Fluorosis" (WS/T 208-2011) and the "Diagnostic Criteria for Endemic Skeletal Fluorosis" (WS 192-2008),respectively.Results A total of 46 villages in 12 counties were investigated,1 992 of water samples,1 662 of tea samples,664 of children urine samples,3 186 of adult urine samples were detected;547 children aged 8-12 were examined dental fluorosis and 3 196 adults were examinea skeletal fluorosis,respectively.The water fluoride contents in all the investigated villages were less than 1.0 mg/L;the average fluoride content in brick-tea water was 6.12 mg/L,within the range of 0.11-84.00 mg/L,and the average daily brick tea fluorine intake of residents was 24.98 mg.The geometric mean of urine fluoride in children and adults was 0.76,2.28 mg/L,respectively.The prevalence rates of dental fluorosis in children and skeletal fluorosis in adults over 16 years old were 31.81％ (174/547) and 48.59％ (1 553/3 196),respectively.The children dental fluorosis index was 0.60.The detection rate of skeletal fluorosis in adults aged 36-45 was 13.37％ (69/516).Conclusions The prevalence of drinking brick-tea type fluorosis in Tibet is serious and widely distributed.In particular,the prevalence rate of skeletal fluorosis in adults is relatively high,while that of dental fluorosis in children is relatively mild.The prevention and control of drinking brick-tea type fluorosis in Tibet brook no delay.

OBJECTIVES: Rhinoplasty is one of the most common cosmetic surgeries in China. Septal extension grafts (SEG) have been widely used in rhinoplasty, but there are few reports on SEG derived from ear cartilage. This study aims to explore the effectiveness and stability of auricular cartilage nasal SEG transplantation in Chinese rhinoplasty. METHODS: A retrospective analysis of 35 rhinoplasty patients admitted from September 2019 to March 2022 has been conducted. Among them, 29 patients underwent rhinoplasty for the first time and 6 patients underwent rhinoplasty with the age of 18-32 (average 22.4) years old. The postoperative follow-up was 3-28 (average 18.5) months. The improvement of the nose shape was observed. The changes of the nose tip angle, nasolabial angle, and nasofrontal angle were compared between before and after the operation, and the complications were recorded. RESULTS: All patients who underwent rhinoplasty with a septal extension grafts constructed from the concha cavity and concha cartilage showed significant improvement in nasal contour. The preoperative nasal tip angle, nasolabial angle, and nasofrontal angle were significantly improved compared with 3 months after operation (all P<0.001), and there was no significant difference between 3 months and 14 months after operation (all P>0.05). The appearance of nasal cavity was satisfactory in 32 patients after operation. Columella deviation occurred in 2 patients and 1 patient complained of downward rotation of the nasal tip, which was satisfied after readjustment of the graft. CONCLUSIONS The simplified SEG derived from auricular cartilage can provide stable support for the nasal tip, the nasal shape is natural after operation, and minimal trauma of unilateral auricle cartilage transplantation remains.
