A consensus on the management of allergy in kindergartens and primary schools / 中国学校卫生

Abstract@#Allergic diseases can occur in all systems of the body, covering the whole life cycle, from children to adults and to old age, can be lifelong onset and even fatal in severe cases. Children account for the largest proportion of the victims of allergic disease, Children s allergies start from scratch, ranging from mild to severe, from less to more, from single to multiple systems and systemic performance, so the prevention and treatment of allergic diseases in children is of great importance, which can not only prevent high risk allergic conditions from developing into allergic diseases, but also further block the process of allergy. At present, there is no consensus on the management system of allergic children in kindergartens and primary schools. The "Consensus on Allergy Management and Prevention in Kindergartens and Primary Schools", which includes the organizational structure, system construction and management of allergic children, provides evidence informed recommendations for the long term comprehensive management of allergic children in kindergartens and primary schools, and provides a basis for the establishment of the prevention system for allergic children.

Objective:To evaluate delayed laparoscopic cholecystectomy (DLC) after percutaneous transhepatic gallbladder drainage (PTGBD) in acute cholecystitis.Methods:Clinical data of 64 patients who were diagnosed moderate (grade Ⅱ) acute cholecystitis by the 2018 Tokyo Guidelines in acute phase and underwent delayed LC at our hospital from Jan 2018 to Jan 2021 were compared between two groups ie PTGBD treatment (21 cases)in acute stage before DLC and DLC without PTGBD group (43 cases). The difficulty score of TG18 was used to evaluated every surgical procedure of the cases by reviewing the operation videos.Results:Patients in DLC after PTGBD group had a longer hospital stay and operation time, more blood lose and higher difficulty score than the DLC without PTGBD group(all P<0.05). There was no statistically significant difference in the conversion rate and morbidity rate between the two groups( P>0.05). Conclusion:This study fails to show there is any if ever benefit of PTGBD before DLC over DLC without PTGBD in the management of Grade Ⅱ acute cholecystitis.

The association between body mass index and varicocele: A meta-analysis

ABSTRACT Objective: Recently, several studies have found that obesity had a protective effect against varicocele, but no meta-analysis has confirmed this finding. Therefore, we conducted this meta-analysis to investigate the association between body mass index (BMI) and varicocele. Material and Methods: We searched for studies in PubMed, Science Direct and the Cochrane Library from inception until February 2018. The association between BMI and varicocele was assessed by pooling the odds ratios (ORs). Results: Eleven eligible studies with a total study population of 1.376.658 participants were included in our analysis. According to BMI, the subjects were defined as belonging to the obese, overweight and underweight groups. Our results showed that the obese group had a lower risk of varicocele when compared with the normal weight group (odds ratio [OR] 0.46, 95% confidence intervals [CIs] 0.37-0.58). Additionally, an overweight BMI had a protective effect against varicocele (OR 0.70, 95% CIs, 0.56-0.86). However, underweight patients had a more than 30% higher risk of varicocele (OR 1.31, 95% CI, 1.04-1.64). Furthermore, there was no publication bias in any of the analyses. Conclusions: Our study demonstrates that BMI is negatively associated with the presence of varicocele.

Objective To investigate the current prevalence of human soil-borne nematode infections in Yunnan province, so as to provide the scientific evidence for formulating the soil-borne nematodiasis control strategy in the province. Methods In 2015, a total of 20 survey sites were sampled in 10 counties (cities) of Yunnan Province using the stratified cluster random sampling method. Stool samples were collected from all local permanent residents at ages of one year and older in each survey site, and the soil-borne nematode eggs were identified using the modified Kato-Katz technique and the egg number was counted. In addition, the hookworm species was identified using the filter-paperculture method, and Enterobius vermicularis eggs were detected using the cellophane tape method in children at ages of 3 to 6 years. Results A total of 5 067 residents received stool examinations, and 950 residents were detected with soil-borne nematode infections, with an overall prevalence rate of 18.75%. The prevalence of Ascaris lumbricoides, Trichuris trichura and hookworm was 7.52%, 8.47% and 9.02%, respectively. Among 446 children detected using the cellophane tape method, 5 children were detected with E. vermicularis infections. Among the 160 residents with hookworm infections, there were 139 residents with Necator americanus infections (86.88%), 16 with A. duodenale infections (10.00%) and 5 with mixed infections (3.12%). Mild A. lumbricoides (67.98%, 259/381), T. trichura (88.58%, 380/429) and hookworm infections (94.53%, 432/457) were predominant. Among the four ecological zones, the highest prevalence of human soilborne nematode infections was found in the East Tibet-South Sichuan Ecological Zone (31.79%), and among the 10 survey counties (cities), the greatest prevalence was seen in Gongshan Derung and Nu Autonomous County (50.13%), while the lowest prevalence was found in Ninglang Yi Autonomous County (0.40%). The prevalence of human soil-borne nematode infections was 5.67% (43/759), 26.67% (610/2 287) and 14.70% (297/2 021) in high-, moderate- and low-economic-level regions, respectively. There were no significant differences in the prevalence of human soil-borne nematode infections in terms of ecological regions, survey counties (cities) or economic development levels (χ2 = 342.20, 814.60 and 201.34, all P < 0.05). There was no significantdifference in the prevalence of human soil-borne nematode infections between male (18.21%, 441/2 422) and female residents (19.24%, 509/2 645) (χ2 = 0.89, P > 0.05), and soil-borne nematode infections were detected in residents at all age groups, with the greatest prevalence found in residents at ages of 1 to 9 years (25.88%). In addition, the highest prevalence of soil-borne nematode infections was seen in residents with the Dulong Ethnic Minority (82.09%), in preschool children (25.06%) and in illiterate residents (24.80%), and there was no age-, ethnicity-, occupation- or education level-specific prevalence of soil-borne nematode infections detected (χ2 = 46.50, 1 016.96, 36.33 and 52.43, all P < 0.05). Conclusions The prevalence of human soil-borne nematode infections remains high in Yunnan Province. The management of soil-borne nematodiasis requires to be reinforced among low-age children, farmers, old people and residents with low educations levels or ethnic groups.

Type 2 diabetes and sleep disorders / 中国药理学通报

Diabetes mellitus is a metabolic disease characterized by chronic hyperglycemia. Recently, the number of diabetic patients in the world is rapidly growing, which has brought a heavy burden to the society. At the same time, changes in lifestyle lead to a general decline in the quality of sleep in the population. Epidemiological and clinical studies have shown a close relation between the development of diabetes and sleep disorders, which may form a vicious circle. Sleep disorders promote the occurrence of type 2 diabetes and affect the glycemic control of diabetic patients; on the other hand, diabetic patients, especially in poor glycemic control, often have sleep disorders. This review discusses the relationship between type 2 diabetes and sleep disorders based on related research, and may provide new strategies for future treatment of diabetes.

·AIM: To observe the clinical effects of microincision vitrectomy combined with internal limiting membrane (ILM) peeling for high myopia patient with macular hole retinal detachment (MHRD). ·METHODS: This was a retrospective non-randomized controlled clinical study. A total of 26 eyes of 26 patients with high myopic MHRD from January 2011 to December 2016 were included. All eyes underwent 23G pars plana microincision vitrectomy combined with ILM peeling. The preoperative and postoperative best corrected visual acuity ( BCVA ), intraocular pressure, ocular anterior segment and fundus examination were observed, and the anatomical closure of macular hole was checked by optical coherence tomography ( OCT). The relationships between final BCVA and these parameters ( age, GASS stage, onset time, OCT pattern of MH closure, initial vision) were examined by regression analysis. ·RESULTS: The postoperative MH closure rate of high myopia MHRD was 58% . OCT images of the repaired MH in high myopia were categorized into 3 patterns: U-type (3 eyes) with relative normal foveal contour; V-type (4 eyes) with steep foveal contour; W-type (8 eyes) with foveal defect od neruosensory retina, but without warped hem of retinal hole or cystic formation. Multivariate Logistic regression analysis showed that postoperative BCVA was correlated with the OCT patternts of closed MH and initial vision ( P< 0. 05 ). The postoperative visual acuity of U-type closed MH was 6. 9 times higher than that of W-type. ·CONCLUSION: Microincision vitrectomy combined with ILM peeling is a safe and effective surgical treatment for high myopia patient with macular hole retinal detachment. The postoperative visual acuity was correlated with the OCT patterns of closed MH and initial vision.

MRI Features and Site-specific Factors of Ischemic Changes in White Matter: A Retrospective Study / 华中科技大学学报（医学）（英德文版）

Brain magnetic resonance imaging (MRI) of the elderly often reveals white matter changes (WMCs) with substantial variability across individuals.Our study was designed to explore MRI features and site-specific factors of ischemic WMCs.Clinical data of consecutive patients diagnosed with ischemic cerebral vascular disease who had undergone brain MRI were collected and analyzed.Multi-logistic regression analysis comparing patients with mild versus severe WMCs was performed to detect independent associations.Analyses of variance (ANOVAs) were used to detect regionally specific differences in lesions.We found that lesion distribution differed significantly across five cerebral areas,with lesions being predominant in the frontal lobe and parieto-occipital area.To explore WMCs risk factors,after adjusting for gender,diabetes mellitus,and hypertension,only age (P＜0.01),creatinine (P=0.01),alkaline phosphatase (ALP) (P=0.01) and low-density lipoprotein cholesterol (LDL-C) (P=0.03) were found to be independently associated with severe WMCs.Age (P＜0.001) was strongly associated with WMCs in the frontal lobe while hypertension was independently related to lesions in the basal ganglia (P=0.048) or infratentorial area (P=0.016).In conclusion,MRI of WMCs showed that ischemic WMCs occurred mostly in the frontal lobe and parieto-occipital area.The infratentorial area was least affected by WMCs.Typically,age-related WMCs were observed in the frontal lobes,while hypertension-related WMCs tended to occur in the basal ganglia and infratentorial area.

CT assisted morphological study of lumbar endplate / 中国骨伤

OBJECTIVE@#To study and measure the anatomic structure of lumbar vertebral endplate structure in healthy adults by computed tomography(CT) technique in order to provide a useful guidance for the optimal design and clinical application of lumbar prostheses.@*METHODS@#Sixty healthy adults (male and female equals) were recruited for full-waist CT scan after signing the informed consent form in the imaging department of the Second Affiliated Hospital of Xi'an Jiaotong University. The scanning data was imported into the computer aided software Mimics 16.0 for 3D reconstruction and measurement. The acquisition indexes included median sagittal diameter, maximum coronal diameter, concavity depth, median sagittal depression angle, coronal depression angle and so on. Finally, the collected data were statistically analyzed by the statistical software.@*RESULTS@#The median sagittal diameter and the maximum coronal diameter of the upper and lower endplates were not only different between the different sexes(0.05), but had a little change from L₁ to L₅, fluctuating from 1.5 to 2.0 mm and from 2.2 to 3.9 mm, respectively. In the same sequence, the concavity depth of lower endplate in males was greater than that of upper endplate, and the difference was statistically significant(0.05). Sagittal concavity angle and coronal concavity angle of upper and lower endplates changed slightly with the increase of vertebral order, and there was no gender difference in sagittal and coronal concavity angle of most vertebral sequences (>0.05). Statistics showed that the largest concavity near the caudal lumbar endplate was located on the dorsal side of the endplate plane.@*CONCLUSIONS@#The anatomical structure of the lumbar endplate is very complicated. It is important to master the anatomical parameters of the endplate and make full use of CT before operation for the development and clinical application of the lumbar prosthesis.

MALDI-TOF MS overcomes the shortcomings of traditional methods and has broad application prospects in detection of bacterial resistance and drug resistance mechanism.This article reviews the recent progress on the application of MALDI-TOF MS in detection of bacterial drug resistance mechanisms.

Classification of upper cervical fractures: a review / 中国骨伤

Upper cervical fracture-dislocations are series of pathological injuries occurred in occipital, atlas and axis caused by traumatic impact, which often results in severe clinical consequences, such as paraplegia, quadriplegia, and even death. In light of the potential severe clinical outcomes, it is important to define the type of upper cervical fracture-dislocations depending on which the clinician can deal with the disease properly. Owing to its specific anatomical structures, the upper cervical fractures occurr to the unique osseous structures or ligamentous connections always present in predictable patterns. Common fracture include occipital condylar fracture, atlanto-occipital dislocation, atlas fracture, and the three types of fractures of axis, including odontoid fracture, Hangman's fracture and axis body fracture. In this paper we will review the literatures about the classification and management of upper cervical fracture, to help the clinicians to treat their patients better.

Utility of optomap panoramic 200Tx in postoperative fundus examination among cataract patients / 国际眼科杂志(Guoji Yanke Zazhi)

To investigate the utility of optomap panoramic 200Tx in screening fundus disease among the patients after cataract surgery. ●METHODS: From November 18 th to December 31st , 2013 all 146 post- cataract surgery patients were recruited. All non - mydriatic fundus images were taken with the optomap panoramic 200Tx and were diagnosed by one masked retinal specialist. Non - mydriatic direct ophthalmoscope exam and mydriatic slit-lamp lens exam were also done by other two masked specialists. Comparisons of the three methods were made. ●RESULTS: Among 146 patients ( 161 eyes), 40 eyes (24. 8%) of retinal lesions was detected by non-mydriatic direct ophthalmoscope exam, 59 ( 36. 7%) by non -mydriatic optomap 200Tx exam, and 61 (37. 9%) by slit-lamp lens exam. Nine eyes ( 5. 6%) needed medical intervention immediately. Results of optomap 200Tx exams and slit - lamp lens exams were similar without statistically significant difference ( P > 0. 05), better than direct ophthalmoscope exam ( P ● CONCLUSlON: Opacification of the refractive medium makes thorough fundus examination impossible. So post-operative fundus examination is highly necessary and should be a routine. Optomap panoramic 200Tx, which shows no statistically difference from mydriatc slit- lamp lens exam, is a convenient and feasible method in discovering fundus pathological changes.
