Objective:To evaluate the technique of reduction and rigid internal fixation of sagittal maxillary fracture. Methods:15 cases of sagittal maxillary fracture were reviewed. Occlusal guide plates were prepared preoperatively by model surgery analysis in 10 cases; Le Fort ? osteotomy and down-fracture were done in 8 cases; Pterygomaxillary junctions were also separated in the other cases. Internal fixation was applied along the anterior maxillary surface by using microplates in all 15 cases. Results:Anatomically reduction was achieved in all cases; Occlusion of 14 cases was corrected except one case of fracture re-displaced. Conclusion:Orthognathic technique is effective treatment of sagittal maxillary fracture; One microplate applied along anterior maxillary surface may be not enough to ensure the fixation of sagittal maxillary fracture.

Objective: To investigate the principle of diagnosis and treatment of orbital fracture. Methods:114 cases of orbital fractures were reviewed. The incidence of major clinical feature was estimated and the surgical procedures were analyzed. Results:Incidence rate of restricted ocular motility, diplopia and enophthalmos were 63.2%, 62.3% and 59.6% respectively; The incidence of optic nerve injury, lacrimal injury and rupture of the globe was 15.8%,15.8% and 12.3% respectively. 95.6% of the cases were undergone orbital wall reconstruction (artificial bone graft) and 72.8% were received fracture reduction and internal fixation. Conclusion:Restricted ocular motility, diplopia and enophthalmos are major symptoms of orbital fracture and optic nerve injury, lacrimal injury and rupture of the globe are important complications of orbital fracture; Orbital reconstruction is the most popular surgical procedure for orbital fracture and bone reduction and internal fixation is also need for impure orbital fracture.

Methods Retrospective analysed a total of 80 the clinical data of patients with traumatic brain treated in Yuyao Municipal People’s Hospital from March 2015 to August 2016 received surgical treatment in emergency, accorded to the intraoperative anesthesia were divided into remifentanil group and combined anesthesia group(remifentanil combined with sufentanil anesthesia group).The changes of MAP,HR and stress indexes in two groups were observed,awakening quality and complication rate between the two groups were compared.Results Before anesthesia,there was no difference between the two groups of MAP and HR levels,10 minutes after the anesthesia,the beginning of the operation and the end of the operation,the combined anesthesia group was higher than that of the remifentanil group ( P<0.05 );there was no significant difference in blood glucose and cortisol levels between the two groups before and after anesthesia,and the indexes of 12h after operation were lower than those in the remifentanil group (P<0.05);two groups of patients with respiratory recovery time,recovery time,eye opening time command and extubation time showed no significant difference between the two groups;nausea and vomiting,incidence of bradycardia and other complications had no significant difference.Conclusion Sufentanil combined with remifentanil in emergency brain trauma surgery anesthesia was better,has little effect on the mean arterial pressure and heart rate,low complication rate.

Objective To study the impact of earlier tracheotomy on the prevention and treatment of pulmonary infection for the patients with severe head injury.Methods The 68 patients with severe head injury(experimental group) received tracheotomy within 24h after emergency cerebrotomy,controlled by 68 patients(control group) who didn't receive tracheotomy within 24h after emergency cerebrotomy.The third generation cephalosporin and semi-benzylpenicillin were used to prevent infection in all the patients.The patients who had lung infection were taken sputum cultivation test to choose sensitive medicine for the treatment.Results A total of 68 patients occurred pneumonia.There were 35 patients occurred pneumonia in the experimental group and 20 patients were cured.The time of infection control was 4～11d(averaged 7.1 d).There were 53 patients occurred pneumonia in control group, and 21 of them were cured.The time of infection control was 9～21d(averaged 16.9 d).The rate of lung infection and the time of infection were significantly lower in the experimental group than those of the control group(P

Objective To explore the predictive value of the expression of serum forkhead box protein M1(FOXM1)and insulin-like growth factor 2(IGF2)on the prognosis of elderly patients with heart failure complicated with pneumonia.Methods A total of 126 elderly patients with heart failure complicated with pneumonia admitted to Handan Central Hospital from March 2021 to June 2022 were included in case group.According to the follow-up results,the 122 patients were grouped into poor prognosis group(n=33)and good prognosis group(n=89).Meanwhile,126 healthy people in the same period were included as the control group.The levels of serum FOXM1 and IGF2,forced vital capacity(FVC)and forced expiratory volume in the first second(FEV1)in the two groups(case group and control group)were measured.Spearman method was used to analyze the correlation between serum levels of FOXM1 and IGF2 and heart function classification in elderly patients with heart failure complicated with pneumonia.The predictive value of serum FOXM1 and IGF2 levels in elderly patients with heart failure complicated with pneumonia was analyzed by receiver operating characteristic(ROC)curve.Results Compared with the control group,the levels of FOXM1(2.39±0.55 vs 1.06±0.21)and IGF2(71.33±7.96pg/ml vs 47.82±5.14pg/ml)in the case group were significantly higher(t=25.358,27.581,all P<0.05).Compared with the good prognosis group,the levels of serum FOXM1(3.87±1.06 vs 1.95±0.51)and IGF2(85.88±9.54pg/ml vs 69.14±8.73pg/ml)in the poor prognosis group were significantly higher,and the differences were statistically significant(t=13.453,9.174,all P<0.05).There were significant differences in heart function classification between the good prognosis group and the poor prognosis group,and the differences were statistically significant(χ2=7.120,P<0.05).Compared with the poor prognosis group,FEV1(1.24±0.32 L vs 1.08±0.25 L)and FEV1/FVC(55.46%±5.77%vs 52.30%±5.38%)in good prognosis group were significantly higher,and the differences were statistically significant(t=2.592,2.735,all P<0.05).The levels of serum FOXM1 and IGF2(r=0.496,0.517,all P<0.05)in elderly patients with heart failure complicated with pneumonia were positively correlated with heart function classification.ROC curve results showed that the area under the curve(AUC)of serum FOXM1 alone in predicting the prognosis of elderly patients with heart failure complicated with pneumonia was 0.854(95CI%:0.779～0.912),with sensitivity and specificity of 75.76%and 86.52%,respectively,and the optimal cut-off value of 2.75.The AUC of IGF2 alone in predicting the prognosis of elderly patients with heart failure complicated with pneumonia was 0.874(95CI%:0.802～0.927),with sensitivity and specificity of 72.73%and 85.39%,respectively,and the optimal cut-off value of 78.30 pg/ml.The AUC of the combination of the two in predicting the prognosis of elderly patients with heart failure complicated with pneumonia was greater than the AUC diagnosed by serum FOXM1 alone and IGF2 alone(Z=2.737,2.413,P=0.006,0.016).Conclusion The serum levels of FOXM1 and IGF2 were increased in elderly patients with heart failure complicated with pneumonia,indicating the combined detection of the two may have a high predictive value for the prognosis of patients.

The Guangdong Province Laboratory Animals Ordinance(the GPLAO),officially enacted and implemented in October 2010,marked a new phase of legal management in the administration of laboratory animals in Guangdong Province.The GPLAO clearly authorizes the laboratory animal monitoring institutes in Guangdong Province to conduct laboratory animal quality monitoring and assume corresponding legal responsibilities.It also specifies the standards for the production and use of laboratory animals,while bringing attention to laboratory animal welfare and ethics.Through the formulation of supporting documents,the active promotion of the standardization and regulation of administrative law enforcement,and the implementation of measures to delegate power,streamline administration,and optimize government services,significant improvements have been made in the standardized management of laboratory animals in Guangdong Province and in supporting the innovative development of biomedicine.Moreover,notable achievements have been made in areas such as the construction of experimental animal technology platforms,standardization work,the preservation and development of unique resources,and talent pool development.However,with the advancements in science and technology,social economy,and legislative work,some aspects in the GPLAO have been identified for improvement.These include the need for clearer provisions on laboratory animal welfare,more specific guidelines for the management of genetically engineered animals,improved regulations on the safety and welfare of practitioners,further refined implementation of the"one-vote veto system",continued promotion of laboratory animal standardization,and the exploration of effective mechanisms for resource sharing.This paper reviews and summarizes the institutional characteristics,post-legislation implementation,and effectiveness of the GPLAO,as well as the issues and countermeasures identified during the implementation.It concludes the laboratory animals management practices in Guangdong Province during the past 10 years,aiming to provide a reference for laboratory animal legislation.

Objective To analyze changes in the percentages of circulating follicular helper T (Tfh) cells and Tfh subsets in patients with systemic lupus erythematosus (SLE) for better understanding their relationships with SLE , and to investigate effects of steroids on circulating Tfh cells .Methods Pe-ripheral blood mononuclear cells (PBMCs) from 27 patients with SLE (including 10 inactive patients and 17 active patients ) and 21 sex-and age-matched healthy donors were analyzed by flow cytometry to detect the percentage of CD4+CD45RA-CXCR5+Tfh-like cells.Disease activity and the concentration of anti-double-stranded DNA ( anti-dsDNA) antibody were evaluated by SLEDAI score ( SLE disease activity index ) and ELISA, respectively.PBMCs from healthy donors were treated with or without prednisone to evaluate its effects on circulating Tfh cells .Twelve patients with SLE were treated with high-dose steriods ( 200-500 mg/d, 2-3 d) and the percentages of circulating Tfh cells and Tfh subsets in them were analyzed before and after treatment .Results No significant difference in the percentage of circulating Tfh cells was ob-served between patients with SLE and healthy donors (P>0.05), but the percentage of Tfh17 cells in pa-tients with SLE was significantly higher than that in healthy donors (P<0.05).Compared with patients with inactive SLE and healthy donors , patients with active SLE had a lower percentage of Tfh 1 cells (P<0.05).Moreover, the percentage of Tfh1 cells was negatively correlated with SLEDAI score (r=-0.44, P<0.05). The percentage of Tfh2 cells in anti-dsDNA antibody-positive group was significantly higher than that in anti-dsDNA antibody-negative group (P<0.05).In vitro treatment of PBMCs from healthy donors with predni-sone could significantly down-regulate the percentage of circulating Tfh (P<0.01), Tfh1 (P<0.05) and Tfh2 cells (P<0.01), and up-regulate the percentage of Tfh17 cells (P<0.01).In vivo treatment of pa-tients with SLE with steriods could significantly down-regulate the percentage of circulating Tfh (P<0.01), Tfh1 (P<0.05) and Tfh2 cells (P<0.01) and up-regulate the percentage of Tfh17 cells (P<0.01).Con-clusion Abnormal distribution of Tfh subsets is correlated with SLE disease activity and anti -dsDNA anti-body .Steroids in the treatment of SLE could affect the percentage of circulating Tfh cells and the distribution of Tfh subsets .

Objective To summarize the effect of eye socket reconstruction in patients with severe depressed eye socket combined anophthalmos and to assess the methods of eye socket reconstruction.Methods Forty patients of severe depressed eye socket combined anophthahnos,from Oct,2001 to Mar,2014,underwent eye socket reconstruction in Beijing Tongren Hospital.Thirty four eye sockets were reconstructed with free flap,the scapular flap in 2 cases,the forearm flap in 17 cases,the lateral arm flap in 15 cases.The reversed submental island flap was utilized in 2 patients.The other 4 cases were treated by implant-retained orbital prosthesis.Results All the patients were followed up for more than 2 years.The flaps survived.The artificial eye could be fitted satisfactorily and the appearance of the ill eye socket was improved significantly.The implant-bodies in orbital bone and the prosthesis were stable without peri-implantitis.Conclusions The flap transfer is effective for eye socket reconstruction in patient with severe depressed eye socket combined anophthalmos.The implant-retained orbital prosthesis is also alternative.The treatment choice must be based on the patient 's own conditions.
