ABSTRACT
Objective: To explore the relevant factors of work-related musculoskeletal disorders (WMSDs) among dentists through Meta analysis, providing a basis for the prevention and control of WMSDs among dentists. Methods: In April 2022, cross-sectional research literatures on the prevalence correlation of WMSDs among Chinese dentists were searched in databases such as China National Knowledge Infrastructure, Wanfang, VIP, PubMed, Web of Science, and Em Base database. The search was conducted from the establishment of the database until April 2022, literatures were selected using keywords such as musculoskeletal disorders and dentists. To extract gender, age, length of service, disease classification and other related influencing factors as indicator, and prevalence was selected as the outcome indicator. After evaluating the quality of the literatures, RevMan 5.3 software was used to calculate the combined RD (95%CI) values of the included literatures. Results: A total of 15 articles were included, with a total sample size of 3646 people. Meta analysis results showed that the prevalence of WMSDs among dentists in China was 80%, and the top three parts of the incidence rates were 65% of the waist, 58% of the neck, and 50% of the back. Gender, age, length of service, region and disease classification all increased the risk of WMSDs, and the combined effect size were 75%, 78%, 71%, 77% and 82% respectively (P<0.05) . Conclusion: The occurrence of WMSDs among dentists in China is related to multiple factors such as gender, age, length of service and disease classification. The above risk factors should be taken into account in the workplace and preventive measures should be actively implemented to prolong the working life of dentists.

Background@#and Purpose To explore the causal relationships of elements of the exposome with ischemic stroke and its subtypes at the omics level and to provide evidence for stroke prevention. Methods We conducted a Mendelian randomization study between exposure and any ischemic stroke (AIS) and its subtypes (large-artery atherosclerotic disease [LAD], cardioembolic stroke [CE], and small vessel disease [SVD]). The exposure dataset was the UK Biobank involving 361,194 subjects, and the outcome dataset was the MEGASTROKE consortium including 52,000 participants. @*Results@#We found that higher blood pressure (BP) (systolic BP: odds ratio [OR], 1.02; 95% confidence interval [CI], 1.01 to 1.04; diastolic BP: OR, 1.03; 95% CI, 1.01 to 1.05; pulse pressure: OR, 1.03; 95% CI, 1.00 to 1.06), atrial fibrillation (OR, 1.18; 95% CI, 1.13 to 1.25), and diabetes (OR, 1.13; 95% CI, 1.07 to 1.18) were significantly associated with ischemic stroke. Importantly, higher education (OR, 0.69; 95% CI, 0.60 to 0.79) decreased the risk of ischemic stroke. Higher systolic BP (OR, 1.06; 95% CI, 1.02 to 1.10), pulse pressure (OR, 1.08; 95% CI, 1.02 to 1.14), diabetes (OR, 1.28; 95% CI, 1.13 to 1.45), and coronary artery disease (OR, 1.58; 95% CI, 1.25 to 2.00) could cause LAD. Atrial fibrillation could cause CE (OR, 1.90; 95% CI, 1.71 to 2.11). For SVD, higher systolic BP (OR, 1.04; 95% CI, 1.00 to 1.07), diastolic BP (OR, 1.06; 95% CI, 1.01 to 1.12), and diabetes (OR, 1.22; 95% CI, 1.10 to 1.36) were causal factors. @*Conclusions@#The study revealed elements of the exposome causally linked to ischemic stroke and its subtypes, including conventional causal risk factors and novel protective factors such as higher education.
ABSTRACT
Vertical one-and-a-half syndrome (VOHS) is a rare ophthalmoplegia syndrome caused by unilateral thalamo-mesencephalic infarct. It is manifested as a conjugate upgaze palsy and a monocular paresis of downward gaze. Recognition of VOHS helps clinical localization. No cases of VOHS with photos or videos of ocular motility have been reported in China. Herein a case of VOHS caused by unilateral thalamo-mesencephalic infarct is reported, in order to improve awareness about the ocular sign.

ABSTRACT
OBJECTIVE@#To provide appropriate treatment strategy and precise genetic counseling through studying the phenotype and genotype of a patient featuring learning difficulty and abnormal gait.@*METHODS@#Detailed history taking, physical examination and auxiliary examination (including neuropsychological evaluation, brain imaging and skeletal system X ray) were conducted. The patient was also analyzed by whole exome sequencing, G banding karyotyping and array-based comparative genomic hybridization (aCGH). Multiples ligation-dependent probe amplification (MLPA) was applied to his parents to determine the origin of genomic variation.@*RESULTS@#In addition to obvious dermatological manifestation (Cafe-au-Lait spots), the patient also had facial abnormalities, ocular disorders, skeletal malformations, neurological manifestations, psychiatric and behavioral abnormalities. Whole exome sequencing and G banding karyotyping were both negative. aCGH has identified a microdeletion at 17q11.2, which encompassed the NF1 and neighboring genes. Neither parents has carried the same microdeletion by MLPA analysis.@*CONCLUSION@#The patient had a de novo 17q11.2 microdeletion, which probably accounted for his neurofibromatosis type 1-microdeletion syndrome phenotype.
ABSTRACT
Objective: To explore the relationship of CT attenuation of pericoronary adipose tissue (PCAT) and the underlying plaque types. Methods: Totally 101 patients with coronary heart disease were enrolled. A total of 196 coronary artery plaques were detected, including 55 non-calcified plaques (group A), 70 mixed plaques (group B) and 71 calcified plaques (group C). The anatomical characteristic indices of plaques and the surrounding PCAT CT attenuation were measured and compared among 3 groups. The impact factors of PCAT attenuation and the correlation with the high-attenuation percentage in plaques were analyzed. Results: Significant differences of the maximum plaque cross-sectional area, plaque volume, reconstruction index, degree of lesion stenosis, percentage of high-attenuation percentage in plaques and average CT value of plaques were found among 3 groups (all P<0.05). In group A, B and C, the high-attenuation percentage in plaques, the average CT values of plaques and PCAT gradually increased in turn, and differences between every 2 groups were all statistically significant (all P<0.05). CT value of PCAT was positively correlated with the high-attenuation percentage in plaques (r=0.677, P<0.05). The high-attenuation percentage in plaques was an independent factor affecting the increase of CT value of PCAT (OR=1.041, P<0.001). Conclusion: With the increase of the percentage of high-attenuation percentage in coronary artery plaques, the progression of coronary atherosclerosis, cellular components and interstitial fibrosis and other tissue remodeling occur around the lesion in PCAT, presenting as gradually increasing CT values on CT images.
ABSTRACT
Objective:To analyze the general situation and traditional Chinese medicine (TCM) syndrome characteristics in patients with coronavirus disease-2019（COVID-19） in Anhui province, and to provide a basis for clinical diagnosis and treatment. Method:The 144 cases of COVID-19 patients in Anhui province were collected from designated hospitals by means of multi-center cross-sectional epidemiological survey. The TCM syndrome information collection table of patients with novel coronavirus pneumonia was created to collect the general data, etiology and pathogenesis, pulse and signs, syndrome type and frequency statistics of the patients, and then summarize and analyze the main symptoms and syndrome distribution characteristics of patients with novel coronavirus pneumonia. Result:The mean age of 144 patients with COVID-19 infection was （43.54±15.91） years old, and the number of males was larger than the number of females (9/7). The age distribution and gender difference of the patients were statistically significant (P<0.05). 36.11%（52/144） of the patients had a history of travel/residence in Wuhan/Hubei province, and 63.89% (92/144) of the patients had a history of close contact with the confirmed patients. The main clinical manifestations included fever, cough, diarrhea, fatigue and poor tolerance. Light red tongue and red tongue were dominant in tongue quality, with mainly greasy coating, slippery pulse, rapid pulse and soft pulse were the main types of pulse. The main types of syndrome differentiation were the common type (76.38%, 110/144), most of which were demonstrated as dampness obstructing the lung and spleen (56.25%, 81/144). There was no significant difference in gender composition and age distribution between two groups. Conclusion:The pathogenesis of COVID-19 patients in Anhui province is closely related to the lung and spleen, and the dampness caused by pathogen of the epidemic virus is the main pathological factor of disease, which is in line with characteristics of dampness epidemic in TCM, also can see concurrently "heat, poison, stasis" for a characteristic.

The treatment mainly starts from the lung and spleen, with the method of warm and moist, or with some traditional Chinese medicines with the function of removing phlegm by warming the lung, dispersing cold by thinning the surface, strengthening the spleen and resolving phlegm, strengthening the lung and fixing the surface, and relieving spasmolysis by wind.
ABSTRACT
Objective@#To describe clinical features and prognosis of segmental zoster paralysis of limbs. @*Methods@#Three patients with segmental zoster paralysis of limbs in Huashan Hospital from January 2018 to January 2019 were reported, and a total of 23 patients (including the presenting three patients) until January 2019 in China were summarized. @*Results@#Case 1: A 72-year-old man developed right foot drop three days after herpes zoster in the right lower limb (L4-5,S1). The electrophysiological study showed incomplete common peroneal nerve injury. He was treated with anti-virus drug, mecobalamine and steroids, and achieved a complete recovery after six months. Case 2: A 62-year-old woman developed difficulty raising the right arm one week after herpes zoster in the right shoulder and upper limb (C5-6). The electrophysiological study showed incomplete axillary nerve injury. He was treated with mecobalamine and ginkgo leaf preparation, and achieved an almost full recovery after six months. Case 3: A 86-year-old woman developed left hand weakness two weeks after herpes zoster in the left upper limb, chest and back (C7-8,T1-3). The electrophysiological study was not performed. She was treated with mecobalamine and ginkgo leaf preparation and got achieved an almost full recovery after three months. @*Conclusions@#Segmental zoster paralysis of limbs was most commonly seen in the elders, within weeks after rash eruptions. Focal motor paralysis appeared in the same segment where the skin eruptions occurred, with the upper limbs being more commonly affected than the lower ones. The electrophysiological study usually showed terminal nerve injuries. The prognosis was relatively good and most of the patients achieved functional recovery.
ABSTRACT
OBJECTIVE@#To investigate the transcriptome profile of genital tubercles (GTs) in male SD rats and explore the mechanism of hypospadias induced by Di (2-ethylhexyl) phthalate (DEHP).@*METHODS@#Forty time-pregnant SD rats were randomly divided into 4 equal groups, namely GD16 group and GD19 group (in which the male GTs were collected on gestation day[GD]16 and GD19 for RNA-seq, respectively), control group and DEHP exposure group (with administration of oil and 750 mg/kg DEHP by gavage from GD12 to GD19, respectively).In the control and DEHP exposure groups, the GTs were collected from the male fetuses on GD19.5, and scanning electron microscopy and HE staining were used to observe the morphological changes.The differentially expressed genes (DEGs) in the GTs were screened using lllumina HiSeq 2000 followed by GO and KEGG enrichment analyses to characterize the transcriptome profile.Immunofluorescence assay was performed to verify the DEGs (Mafb) identified by RNA-seq results.Immunofluorescence assay and Western blotting were used to examine the expression levels of Mafb in the penile tissue.@*RESULTS@#A total of 1360 DEGs were detected in the GTs between GD16 group and GD19 group by RNA-seq.Among these genes, 797 were up-regulated and 563 were down-regulated.These DEGs were mainly enriched in the cell adhesion plaque signaling pathway, axon guidance signaling pathway, and extracellular matrix receptor signaling pathway.Compared with that in GD16 group, Mafb was significantly up-regulated in GD19 group, which was consistent with the sequencing results.Mafb and β-catenin were significantly down-regulated in DEHP-exposed group compared with the control group ( < 0.01).@*CONCLUSIONS@#Mafb expression increases progressively with the development of GTs in male SD rats.DEHP exposure causes significant down-regulation of Mafb and β-catenin, suggesting that β-catenin signaling pathway that affects Mafb is related to DEHP-induced hypospadias in SD rats.

A total of 205 cases of patient with early diabetic nephropathy treated in our hospital from March 2014 to April 2016 were selected and divided into two groups according to the admitted order, with 103 cases in clinical group and 102 in control group. Patients in control group were treated with melbine and captopril, which may be adjusted according to the clinical symptom. The clinical group was given Shenqi Dihuang decoction. Then the clinical efficady, inflammatory factors, renal function, endothelial function and hemorheology index were compared. Compared with 77.45% in the control group, the total effective rate of the clinical group was 92.23%. There was a significant increase (<0.05). The comparison of the values of IL-6, IL-8, TNF-α and CRP between the two groups before and after treatment showed significant differences. The values of inflammatory factors in treatment group were lower than in control group (<0.05). The comparison of the values of β2-MG, Cys-C and urine m-ALB between the two groups before and after treatment showed significant differences. The values of renal function in treatment group were lower than those in control group (<0.05). Compared with before treatment, ET-1 of the two groups after treatment decreased, while NO increased (<0.05). Compared with the control group, the value of ET-1 in patients of the experimental group was lower after treatment, while NO was higher (<0.05). The comparison of the values of whole blood viscosity, plasma viscosity, whole blood reduction viscosity, platelet aggregation rate and fibrinogen between the two groups before and after treatment showed significant differences. The value of hemorheology index in treatment group was lower than that in control group (<0.05). Shenqi Dihuang decoction has a better effect on patients with early diabetic nephropathy. It can significantly intervene with inflammatory response, reduce proteinuria, protect the renal function of patients, and improve the patient's vascular endothelial function and blood rheology, so as to make microcirculation to recover to the normal level.

ABSTRACT
<p><b>BACKGROUND</b>Ankylosing spondylitis (AS) is the most common rheumatic condition that is slowly progressive and predominantly affects adolescents. Pathological bone formation associated with AS is an important cause of disability. The aim of the study was to investigate the possible involvement of the genes related to endochondral ossification and ectopia ossification in genetic susceptibility to AS in a Chinese Han population.</p><p><b>METHODS</b>Sixty-eight single nucleotide polymorphisms (SNPs) from 13 genes were genotyped in discovery cohorts including 300 AS patients and 180 healthy controls. The rs10019009 in dentin matrix protein 1 (DMP1) gene shown as association with AS after multiple testing corrections in discovery cohorts was replicated in a validation independent cohort of 620 AS patients and 683 healthy controls. The rs10019009 was assessed with bioinformatics including phylogenetic context, F-SNP and FastSNP functional predictions, secondary structure prediction, and molecular modeling. We performed a functional analysis of rs10019009 via reverse transcription-polymerase chain reaction, alkaline phosphatase (ALP) activity in human osteosarcoma U 2 OS cells.</p><p><b>RESULTS</b>Interestingly, the SNP rs10019009 was associated with AS in both the discovery cohort (P = 0.0012) and validation cohort (P = 0.0349), as well as overall (P = 0.0004) in genetic case-control association analysis. After a multivariate logistic regression analysis, the effect of this genetic variant was observed to be independent of linkage disequilibrium. Via bioinformatics analysis, it was found that the amino acid change of the rs10019009 led to changes of SNP function, secondary structure, tertiary conformation, and splice mode. Finally, functional analysis of rs10019009 in U 2 OS cells demonstrated that the risk T allele of the rs10019009 increased enzymatic activity of ALP, compared to that of the nonrisk allele (P = 0.0080).</p><p><b>CONCLUSIONS</b>These results suggested that the DMP1 gene seems to be involved in genetic predisposition to AS, which may contribute to the ectopic mineralization or ossification in AS. In addition, DMP1 gene may be a promising intervention target for AS in the future.</p>
