OBJECTIVE: To review the ARDs of ready-made Chinese drugs included in OTC list .METHODS: 160 cases of ARDs induced by ready-made Chinese drugs,reported in Chinese journals over 40 years(1960～2000),were analysed .RESULTS: 34 kinds of drugs were involved in inducing ARDs, of which, Huoxiang Zhengqi liquid was the most common one( 19 cases), essense of Fengyou and pseudo-ginseng tablet were the next(16 cases and 13 cases respectively).The ARDs in duced by above-mentioned 3 drugs accounted for 41.4% of total ARDs.Hypersensitive reaction was the most common ARD (67.2%) . 115 of 116 cases were cured, one died.CONCLUSION: Ready-made Chinese drugs can induce ARDs, so the consumers should pay attention to it, however,they need not feel frieghtened,so long as the drugs are used rationally, the incidence of ARDs is very low and the prognosis is good.

Objective To observe the effects of combined surgeries for the correction of congenital ptosis accompanied by epicanthus.Methods 80 cases (105 eyes) of congenital ptosis were analyzed in this study.64 cases (80 eyes),with levator muscle strength more than 4 mm,were treated with suspension of frontal aponeurosis,and 16 cases (25 eyes),with levator muscle strength less than 4 mm,were treated with shorten operation of levator palpebrae superioris.Furthermore,all these patients were corrected the epicanthus at the same time.Results Except the under correction in 5 cases (8 eyes),the remaining patients were corrected satisfactorily.Postoperative palperbal fissure length was averagely increased by 2.0± 1.0 mm,inner canthic diameter was averagely decreased by 4.0± 2.0 mm,the eyelid height was increased by average 9.0±1.0 mm,the inclination of palpebral fissure was 12.0°±2.0°;64 cases (80 eyes) were treated with suspension of frontal aponeurosis,postoperative recurrence were 7.5％ (6/80),no postoperative recurrence were 92.5％ (74/80),complication were 5.0％ (4/80);16 cases (25 eyes) were treated with shorten operation of levator palpebrae superioris,postoperative recurrence were 8.0％ (2/25),and no postoperative recurrence were 8.0％ (2/25);complication rates were 4.0％ (1/25).Conclusions This procedure of combined surgeries can reduce the recurrence rate effectively.Moreover,the satisfactory,functional,and aesthetic results can be obtained simultaneously with this method.

Objective To evaluate the clinical effect of the individualized treatment of congential entropion.Methods Totally 150 patients (285 eyes) with congenital entropion were analyzed,the individualized procedures were performed,including the simple incision and suture surgery for simple congenital entropion,removing the redundant skin of lower eyelid for congenital entropion with redundant skin of lower eyelid but without epicanthus,the correction of entropion combined withY-V epicanthoplasty for congenital entropion with epicanthus and the recession of lower eyelid retractor for congenital entropion with lower eyelid retraction.The clinical effect,the percentage of cure and the complication of these cases were evaluated.Results The excellent results were achieved and no relapse or complications occurred in all cases.The total cure rate was 98.6％ (281 of 285 eyes).The cure rate of simple congenital entropion was 92.0％ (23 of 25 eyes).The cure rate of congenital entropion with redundant skin of lower eyelid was 100％ (41 of 41 eyes).The cure rate of congenital halflength entropion accompanied by epicanthus was 99.4 ％ (179/180 eyes).The cure rate of congenital entropion associated with lower eyelid retraction was 97.4％ (38 of 39 eyes).Conclusions Individualized operations not only have well curative effect for various congenital entropions,but recurrence rate and complications have been reduced.

Objective To observe any influence of hyperbaric oxygen (HBO) treatment on the formation of glial scars,and to explore how HBO suppresses the inflammatory reaction to injury.Methods A total of 96 healthy,adult,male,Sprague-Dawley rats were used to model cerebral puncture injury.They were then randomized into a control group and a treatment group,with 48 rats in each group.The treatment group received HBO treatment,while the control group received no special treatment.At 1,3,7,14 and 28 days after the puncture injury,the rats' right brain tissues were harvested and immunohistochemical staining was employed to compare the changes in number of astrocytes and microglial cells around the injury in the two groups.The level of tumor necrosis factor α (TNF-α) and interleukin 1 β (IL-1β) in the cerebral tissue was examined using ELISA.Results Among the control group the average wound areas after 7,14 and 28 days were (2.73 ± 0.05)μm2,(3.42 ± 0.18)μm2 and (2.41 ± 0.09) μm2,a significant reduction after 28 days compared with 7 and 14 days.The corresponding average wound areas of rats in the treatment group were (2.78±0.12)μm2,(2.59 ±0.08)μm2 and (1.20 ±0.06)μm2.There the average wound area had decreased significantly after 14 days,and the further reduction after 28 days was also significant.The numbers of GFAP-positive astrocytes at 14 and 28 days had increased significantly compared with after 7 days in both the control group and the treatment group.The average number of GFAP-positive astrocytes in the control group at 28 days had decreased significantly compared with after 14 days.Compared with the control group at the same time points,the number of GFAP-positivc astrocytes in the treatment group was significantly less.After modeling,the number of ionized calcium-binding adapter molecule Ⅰ (Ibal)-positive microglial cells increased significantly,but there was a significant decrease in both the control and treatment groups by 7 days.The average number of Ibal-positive microglial cells in the treatment group was significantly less than in the control group at all of the time points.Compared with the first day after modeling,the TNF-α concentration of the controls at 3 and 7 days was significantly higher,but by the 7th day it was significantly lower than it had been after 3 days.The average IL-1β concentration in the control group and TNF-α concentration in the treatment group had increased by day 3,but then decreased by day 7.The IL-1β concentration of the treatment group declined gradually.The average TNF-α and IL-1 β concentrations of the treatment group were significantly lower than those of the control group at all of the time points.Conclusion HBO treatment has a relatively good curative effect on cerebral puncture injury.It can accelerate wound healing and reduce the formation of glial scars.Its mechanism could be related to the deactivation of astrocytes and microglia cells and reducing the levels of cell factors that promote inflammation.

Objective To investigate the expression of suppressor of cytokine signaling-3 (SOCS-3) gene in placenta,its role in the pathogenesis of pre-eclampsia and its effect on proliferation and migration of HTR-8/SVneo cells.Methods Fifteen women with severe pre-eclampsia hospitalized in the First Affiliated Hospital of Nanjing Medical University from October 2010 to March 2011 and t 5 normal pregnant women during the same time period were investigated.Cultured HTR-8/SVneo cells were transfected with SOCS-3 specific small interfering RNA (siRNA) or negative siRNA as the controls.The expression of SOCS-3 mRNA and protein in placenta and these cells was detected by real-time quantitative reverse transcription-polymerase chain reaction and Western blot.Cell proliferation was detected by methyl thiazolyl tetrazolium,cell cycle by flow cytometry and migration by the Transwell test.Two independent t tests were used for statistical analysis.Results The SOCS-3 mRNA and protein levels in the severe pre-eclampsia group were lower than those in the normal group (0.25±0.03 vs 0.71±0.08 and 0.21±0.05 vs 0.75±0.12,t=15.94 and 14.29,respectively,both P＜0.05).SOCS-3 mRNA and protein levels in the transfection group at 24 hours were lower than those in the negative control group (0.39±0.02 vs 1.00±0.04 and 0.003 7±0.001 4 vs 1.514 9±0.035 7,t=27.58 and 73.35,respectively,both P＜0.05).The integral absorbance values of cell proliferation in the transfection group at 48,72 and 96 hours after transfection were 0.23 ± 0.01,0.32±0.02 and 0.37± 0.02,respectively,which were lower than those in the negative control group (0.39± 0.02,0.55 ± 0.04 and 0.86± 0.04,t=2.60,6.64 and 42.44,respectively,all P＜0.05).The cell clonal formation was lower in the transfection group compared with the negative group (116± 15 vs 312±24,t=9.96,P＜0.05).The ratios of G1/G0 and S phase cells in the transfection group were (55.75±2.21) ％ and (31.59±0.83) ％,respectively,and were significantly different from those in the negative control group [(47.88± 1.87) ％ and (37.38± 1.34) ％,t=45.43 and 20.06,respectively,P＜0.05].After 48 hours,cell migration in the transfection group was lower than that in the negative control group (93 ± 11 vs 167± 17,t=21.36,P＜O.05).Conclusion SOCS-3 expression is probably involved in the pathogenesis of pre-eclampsia by being down-regulated and therefore impeding proliferation and migration of the trophoblast.

Objective To investigate the iodine nutrition level of vulnerable people in Inner Mongolia after adjustment of iodized salt standard and to provide theoretical bases for scientific iodine supplementation. Methods In 2013, 3 cities were selected from eastern, central and western parts of Inner Mongolia in accordance with the random number table, 3 or 4 counties were selected from each target city, 5 units according to their sub-area position of east, south, west, north and center were selected from each county, and then 1 township was selected from each unit, 5 groups of target population including school children aged 8- 10, women of childbearing age, pregnant and lactating women and infants each at least 10 people were investigated in each township. Edible salt samples from their homes and urine samples were collected. The direct titration method among the generic methods of iodide testing for salt production industry (GB/T 13025.7-2012) was used to determine the salt iodine level, and As3+-Ce4+catalytic spectrophotometry using ammonium per sulfate digestion (WS/T 107-2009) was used to test the urinary iodine level. Results Totally 3 300 samples of edible salt from local residents had been examined and median iodine was 26.20 mg/kg. The median of urinary iodine was 190.6μg/L of 1 289 school-age children;was 183.6μg/L of 621 women of childbearing age; was 178.2 μg/L o f 876 pregnant women; was 178.6 μg/L of 664 lactating women and was 167.7μg/L of 599 infants. Conclusion After adjustment of iodized salt standard, iodine nutrition level is suitable in all vulnerable people.

Objective To understand the iodine nutritional status of medical examination people and the thyroid dysfuction rates under different urinary iodine.Methods A total of 2 650 medical examination people from Inner Mongolia National Examination Medical Center from March to December of 2018 were selected.The average age was (46.2 ± 12.5) years old,including 697 males and 1 953 females.Blood samples were collected for determination of thyroid function [thyroid stimulating hormone (TSH),thyroid peroxidase antibody (TPOAb),thyroglobulin antibody (TgAb),free thyroxine (FT4),and free triiodothyronine (FT3)],and according to the results of the examination,people were divided into normal thyroid function,subclinical hypothyroidism,subclinical hyperthyroidism,hypothyroidism,hyperthyroidism,autoimmune antibody abnormalities,and other abnormal groups.Urine samples were collected to detect urinary iodine levels,to analyze the thyroid dysfuction rates of each group people and different urinary iodine.The thyroid function was detected by automatic electrochemiluminescence immunoassay analyzer,the urinary iodine was determined by arsenic cerium catalytic spectrophotometry.Results Among the 2 650 medical examination people,there were 1 270 patients with abnormal thyroid function,and the total abnormal rate was 47.92％.The abnormal rates of males and females were 28.84％ (201/697) and 54.74％ (1 069/1 953),respectively,and the abnormal rate of females was higher than that of males (x2 =376.19,P ＜ 0.05).The urinary iodine medians of each group were 145.38,152.60,103.21,176.31,134.17,138.92,and 127.00 μg/L,all in the appropriate range of iodine (100-199 μg/L).Thyroid abnormal rates [55.56％ (125/225),50.86％ (445/875)] of urinary iodine ≥ 300 μg/L (iodine excess) group and ＜ 100 μg/L (iodine deficiency) group were higher than that of 100-199 μg/L group [44.70％ (460/1 029),x2 =12.65,12.61,P ＜ 0.05].Among thyroid abnormal people,autoimmune antibody abnormalities people was the most,accounting for 69.61％ (884/1 270).Urinary iodine was positively correlated with FT4 and FT3 (r =0.04,0.05,P ＜ 0.05);FT4 was negatively correlated with TSH and TgAb (r =-0.20,-0.73,P ＜ 0.05),and it was positively correlated with FT3 (r =0.52,P ＜ 0.05);TPOAb was positively correlated with TgAb (r =0.64,P ＜ 0.05).Conclusions Urinary iodine of medical examination people is in the appropriate range of iodine,indicating that the overall iodine nutritional status is good.However,some people still have iodine excess and iodine deficiency,both of which lead to an increase in thyroid abnormal rate.

Objective To understand the current iodine nutritional status of pregnant women in Inner Mongolia, and provide scientific basis for iodine supplementation during pregnancy. Methods In 103 banners (counties, cities and districts) of Inner Mongolia Autonomous Region, 5 townships were randomly selected according to their sub-area positions of east, west, south, north and center in each banner (county, city and district) in 2018. Twenty pregnant women in each township were sampled to collect edible salt and a random urine samples. The iodine in salt was determined by direct titration. Urinary iodine was detected by As3+-Ce4+catalytic spectrophotometry. According to different pregnancy, maternal age and regional type, the iodine nutrition level of pregnant women was analyzed. Results Totally 9809 pregnant women were investigated, the median of salt iodine was 23.4 mg/kg, iodized salt coverage rate was 98.03％(9616/9809), qualified iodized salt consumption rate was 93.32％(9154/9809), and the median of urinary iodine was 167.20 μg/L. Between different pregnancy and different age groups, there were no significant differences in qualified iodized salt consumption rate (P > 0.05). But the difference between different regions was statistically significant(P<0.05). Between different age groups, there was no significant difference in the median of urinary iodine(P > 0.05). In both different pregnancy and different regions, there were statistically significant differences between groups (P < 0.05). Conclusions The current iodine nutrition level of pregnant women in Inner Mongolia is suitable to meet the physiological needs of themselves, and the fetus. But pregnant women in different regions have different levels of iodine nutrition.

In 2022, World Health Organization (WHO) launched the 5th edition of the classification of renal tumors. This classification continues to use the previous classification framework of renal tumors based on morphology and tissue structure, and proposes the concept of renal cell carcinoma defined by molecular features for the first time. This article interprets from the 3 aspects of historical changes of WHO classification and grading of renal tumors, comparison of 2022 and 2016 WHO classification of renal tumors, and the role of molecular characteristics in the new pathological types such as ELOC mutant renal cell carcinoma, ALK rearrangement renal cell carcinoma, eosinophilic solid and cystic renal cell carcinoma. The purpose is to better understand the WHO from the traditional classification system based on tissue morphology to a three-in-one integrated classification system covering morphology, immunophenotype and genetic characteristics, and to understand the important value of molecular pathology in guiding the work of pathologists and clinicians under the new classification system.

Objective:To study the iodine nutrition status of children in non-high water iodine areas of Inner Mongolia Autonomous Region, analyze the monitoring results of iodine deficiency disorders, so as to provide a basis for further guidance on scientific iodine supplementation for children in Inner Mongolia Autonomous Region.Methods:According to the requirements of the National IDD Monitoring Program and the IDD Monitoring Program of Inner Mongolia in 2021, cluster sampling method was used to select non boarding children aged 8 - 10 from 104 counties (cities, districts) in 12 cities within the jurisdiction of Inner Mongolia Autonomous Region. Random urine samples and household salt samples were collected to detect iodine content. At the same time, 1/3 of the selected children were selected for thyroid B-ultrasound examination to measure thyroid volume.Results:In 2021, a total of 19 968 children aged 8 - 10 in non-high water iodine areas of Inner Mongolia were monitored, and 19 968 urine samples were collected, with a median urine iodine of 199.23 μg/L. There was a statistically significant difference in the frequency distribution of urinary iodine in different cities (χ 2 = 839.51, P < 0.001). The median iodine content of children's household edible salt was 22.64 mg/kg, and the coverage rate of iodized salt, qualified iodized salt coverage rate, and non-iodized salt rate in the entire region was 99.05% (19 778/19 968), 94.98% (18 785/19 778), 94.08% (18 785/19 968) and 0.95% (190/19 968), respectively. Thyroid B-ultrasound were performed in 6553 children, the goiter rate was 1.30% (85/6 553), and there were statistically significant differences in goiter rates among children of different ages and cities (χ 2 = 87.09, P < 0.001; χ 2 = 10.40, P = 0.006) . Conclusions:In 2021, the iodine nutrition of children aged 8 - 10 in non-high water iodine areas of Inner Mongolia is at an appropriate level. However, in the future we should continue to adhere to the monitoring of iodine deficiency disorders, strengthen health education on iodine deficiency disorders, consolidate existing achievements in iodine deficiency disease prevention and control, and achieve the goal of continuous elimination of iodine deficiency disorders.
