Osteosarcoma of the jaw (JOS), is a relatively rare type of osteosarcoma, with a unique pathogenesis and pathological manifestations. The clinical manifestation of JOS is not characteristic, and it often needs to be diagnosed by combining radiological and pathological examination. At present, the conventional treatment of JOS is a comprehensive treatment based on surgery and supplemented by radiotherapy and chemotherapy. Recently, the emergence of new therapies such as immunotherapy, gene therapy, phototherapy and traditional Chinese medicine has provided more choices for treatment and brought new hope to patients with JOS. Therefore, this article summarized the current understanding of diagnosis and the latest treatment development of JOS.

Objective This study aims to provide craniofacial features and incisor position prediction models among esthetics population after orthodontic treatment.Methods A total of 338 patients with esthetic profiles were se-lected from 1 055 post-orthodontic adults based on inclusion and exclusion criteria and scored by five dental students.Mean values of cephalometric measurement were demonstrated with gender and sagittal skeletal pattern(ANB)differ-ences assessed by generalized estimating equation.Correlations among age,skeletal,and soft tissue variables in differ-ent genders were determined.Multivariate analysis was used to assess the influence of skeletal and soft tissue variables on orthodontic incisor position.Results Within the esthetic cohort after orthodontic treatment,gender differences ex-isted in cranial and mandibular length,mandibular rotation,protrusion of pogonion,inclination of maxillary incisors,upper lip thickness,lower 1/3 face height,and nose protrusion.However,in class Ⅰ malocclusion,the development of the chin showed no significance,whereas the protrusion of the lower lip significantly differed between genders,with less protrusion in males.In males,the protrusion of lip and chin varied among groups,with thinner basic upper lip thick-ness of class Ⅱ than class Ⅰ and greater lower lip height of class Ⅲ than class Ⅰ.In females,the protrusion and height of the upper lip and chin varied in groups,with thicker basic upper lip thickness of class Ⅲ than class Ⅰ.Upper lip thickness,female basic upper lip thickness,and female lower lip height were correlated with age.The protrusion of the upper lip was mainly correlated with posterior cranial base,mandibular body length,ANB in male and SNA,ANB,sag-ittal maxillary length,mandibular rotation,and protrusion of pogonion in female.The protrusion of the lower lip in males was mainly correlated with ramus height,mandibular rotation,protrusion of pogonion in male and ANB,mandib-ular rotation,and protrusion of pogonion in females.After employing skeletal variables to fit dental parameters,optimal results were achieved in male IMPA(adjusted R2=0.712)and female G Vert-U1(adjusted R2=0.795).After employing skeletal and soft tissue variables simultaneously,optimal results were achieved in male and female G Vert-U1,which was mainly influenced by the protrusion of the chin and nasal base in males(adjusted R2=0.836)and the protrusion of the nasal base as well as ANB in females(adjusted R2=0.842).Conclusion This study demonstrated the craniofacial features of esthetics population after orthodontic treatment and revealed the correlation of gender,age,skeleton,and soft tissues to provide reliable prediction models for aesthetic orthodontic incisor position.

Objective:To analyze the impact of COVID-19 epidemic on syphilis case reporting in China, and provide evidence to evaluate the epidemic situation of syphilis and strengthen the prevention and control of syphilis during COVID-19 epidemic.Methods:The data were collected from the National Notifiable Infectious Disease Reporting System of China Information System for Disease Control and Prevention, National STD Management Information System, and the "nCov2019" R package of github website. The changes of reported cases of syphilis before and during COVID-19 epidemic in China were analyzed. Joinpoint regression model was established by using the reported case number of syphilis from 2010 to 2018, the data in 2019 was used for validation, and the number of syphilis cases in 2020 and 2021 was predicted. The impact of COVID-19 epidemic on the number of syphilis cases was evaluated with calculating the percentage error (PE) between actual number and predicted number of syphilis cases reported.The correlation between reported cases of syphilis and COVID-19 was analyzed by Spearman's correlation analysis. The softwares of Joinpoint 4.9.1.0 and SPSS 18.0 were used for statistical analysis.Results:In 2020 and 2021, the reported cases of syphilis in China decreased significantly by 13.32% and 10.41%, respectively, compared with 2019 (before COVID-19 epidemic), and the reported cases of syphilis in 2021 increased by 3.36% compared with 2020. The reported cases of syphilis in 2020 and 2021 decreased by 17.95% and 20.41%, respectively, compared with predicted numbers. From January to March 2020, the reported monthly case number of syphilis was completely negatively correlated with the confirmed case number of COVID-19 ( r s=-1.00, P<0.001). In the provinces with different scales of COVID-19 epidemic, there was also a negative correlation between the monthly reported case number of syphilis and confirmed case number of COVID-19 (all P<0.05). Conclusions:In China, the change of reported cases of syphilis was closely associated with COVID-19 epidemic in 2020 and 2021. Due to the influence of COVID-19 epidemic, the number of reported cases of syphilis decreased significantly, but it should not be thought that syphilis incidence will become a decline trend in the future. It is necessary to carefully and scientifically assess the changes in syphilis epidemic.

Objective To summarize the brain protection application experiences of combined internal and external blood shunt technologies for the in-situ three-fenestration revascularization of aortic arch.Methods From Feb 2017 to Jun 2018,8 patients with aortic arch leisons were treated by the in-situ three-fenestration techniques,including 3 aortic dissection,2 aortic aneurysm,3 postoperative TEVAR patients.We adopt the method of internal and external blood shunt technologies for brain protection using the vascular sheath for fenestration combined with carotid shunt tube skills,and using TCD to monitor the blood flow of brain.Results All operations completed successfully,and TCD showed no significant cerebral ischemia when aortic stent was used to cover the three branches of the aorta.The mean time of brain protection was (17.62 ± 6.87) minutes.One patient developed transient cerebral ischemia after surgery,and another one developed cerebral infarction.Conclusions The brain protection strategy of internal bypass combined with external converter technology maintain the brain blood flow,while is simple and feasible,it cannot completely avoid neurological complications.

Objective:To investigate the efficacy of shunt after transjugular intrahepatic portosystemic shunt (TIPS) in liver cirrhosis accompanied with portal vein thrombosis (PVT).Methods:Forty-four cases with liver cirrhosis accompanied with PVT who underwent TIPS treatment from January 2015 to May 2018 were retrospectively analyzed. Clinical baseline data of the patients were collected. Portal vein pressure gradient (PVPG) before and after the surgery was recorded. Shunt patency was observed at 3, 6, 12, 18 and 24 months after the surgery. The influencing factors were determined by univariate and multivariate analysis.Results:Transjugular intrahepatic portosystemic shunt was successfully established in all 44 cases. The postoperative PVPG was lower than preoperative ( P < 0.01). The shunt patency rate after TIPS in PVT was 18.2% ( n = 8). The cumulative shunt patency rates at 3, 6, 12, 18, and 24 months after surgery were 95.5%, 90.7%, 90.7%, 86.8% and 74.4%, respectively. Univariate analysis showed that diabetes history, platelet level and prothrombin time-international normalized ratio were associated with postoperative shunt dysfunction. Multivariate analysis showed that diabetes history ( P = 0.007, OR = 28.606) was an independent risk factor for postoperative shunt dysfunction. Conclusion:TIPS is a safe and feasible procedure, which can effectively reduce the portal pressure in liver cirrhosis accompanied with PVT. Diabetic patients have a higher risk of postoperative shunt dysfunction. Therefore, clinical intervention should be strengthened for high-risk patients.

Objective: To explore the prevalence of occupational musculoskeletal disorders (OMD) and its influencing factors among rural migrant workers in Tianjin, with the aim of developing strategies to improve the health condition of this specific population. Methods: Questionnaire survey was conducted among 415 rural migrant workers working in Tianjin about their fundamental state and occupational musculoskeletal disorders (OMD) during January 2015 to January 2016. Statistical methods were utilized to analyze the influencing factor. Results: A total of 415 rural migrant workers were investigated, in which young Young adults and low education level were in the majority of rural migrant workers. The prevalence of OMD for whole population, male and female were 28.92% (120/415), 33.06% (81/245) and 22.94% (39/170), respectively. Prevalence showed significant differences njin and workplace hygiene. Multivariate logistic regression analysis showed that the risks of OMD increased with age group, and decreased with higher education level. The risk of OMD among rural migrant workers with monthly income between 3000 to 5000 yuan was 2.26 times (95%CI: 1.37-3.75) higher than that of low-income workers (<3000 yuan per month). Workers engaged in housekeeping service had 2.28 times higher risk of OMD than those in manufacturing industry (95%CI: 1.06-4.89) . Conclusion Prevalence of OMD among rural migrant workers is higher than that of general people. Age, education, monthly income, occupation are the independent influencing factors for OMD among rural migrant workers.

Objective To evaluate the safety and clinical short-term efficacy of interventional emboliz-ation with hepasphere-loaded microspheres in treating inoperable hepatocellular carcinomas. Methods A total of 15 patients with unresectable hepatocellular carcinoma underwent transcatheter arterial chemoembolization ( TACE ) using hepasphere-loaded microspheres as embolic agent . The clinical data , imaging follow-up materials, complications of interventional treatment, prognosis, etc. were summarized and analyzed. The results were evaluated with modified response evaluation criteria in solid tumors (mRECIST); monthly follow-up was made for all patients. A total of 23 TACE procedures were performed in 15 patients. Results The following-up period ranged from 6 months to 15 months , the median follow-up time being 10 months . According to mRECIST, the 3-month objective response rate (CR+PR) was 73.3% and disease control rate (CR+PR+SD) was 93.3%;the 6-month objective response rate (CR+PR) was 73.3%and the disease control rate (CR+PR+SD) was 86.7%. No severe complications, such as bile leak complicated by infection, liver abscess, abdominal hemorrhage, bleeding due to tumor rupture, gastrointestinal bleeding, etc. occurred in all patients . Conclusion In treating unresectable hepatocellular carcinomas , TACE using newly-developed hepasphere microspheres carries satisfactory clinical short-term efficacy and safety, although thelog-term results need to be further investigated with larger sample trial.

Objective To explore the application of transcatheter arterial chemoembolization (TACE) combined with selective portal vein embolization (SPVE ) in two-stage hepatectomy of hepatocellular carcinoma (HCC).Methods From September 2010 to September 2013,a total of 107 patients with HCC in the right liver lobe who were not suitable for one stage hepatectomy received TACE or TACE combined with SPVE treatment were enrolled.Among them,55 received TACE therapy and 52 accepted TACE combined with SPVE treatment.The technique success rate,complication,adverse reactions,the volume change of each liver lobe and the rate of hepatectomy of HCC were observed.Chi-square test was used for numerical data comparison and Student′s t test for measurement data.Results TACE or TACE combined with SPVE therapy was successfully applied in all the 107 patients,the technique success rate was 100%.During treatment period,no complications such as ectopic embolization, liver function failure,puncture tract bleeding,gastrointestinal bleeding,bile leakage and hepatic abscess were observed.After treatment,the adverse reactions included liver function impairment,pain in hepatic region,fever,nausea and vomiting.Four weeks after the treatment,the volumes of tumor and right liver lobe decreased to certain degree in patients with HCC of both TACE group and TACE combined with SPVE group.The volume of left liver lobe in TACE group had no obvious change,while remarkably increased in TACE combined with SPVE group.The pre-treatment residual liver volume (RLV)of TACE group and TACE combined with SPVE group was (404.0 ± 46.3 )cm3 and (393.9 ± 65 .7 )cm3 , respectively,and the difference was not statistically significant (t=0.927,P =0.356).Four weeks after the treatment,RLV was (415.4 ±45.7 )cm3 and (567.3 ±88.7 )cm3 ,respectively,and the difference was statistically significant (t= -11 .219,P <0.05).Patients were followed up for three to six months,the rates of hepatectomy were 38.2%(21/55)and 86.5 %(45/52)in TACE group and TACE combined with SPVE group,and the difference was statistically significant (χ2 =26.440,P <0.01 ).Conclusion For patients with HCC not suitable for one stage hepatectomy,the treatment of TACE combined with SPVE before operation could effectively control the growth of the tumor,decrease the volume of tumor,increase RLV,and then increase the rate of two-stage hepatectomy.
