Objective:To compare 3 maxillofacial trauma scoring systems in mandible fracture grading.Methods:Maxillofacial Injury Severity Score(MISS),Maxillofacial Injury Severity Score(MFISS),Mandible Injury Severity Score(S5)were used in the analysis of mandible fracture severity in 313 cases with mandible fractures.The results were statistically analyzed.Results:S5 score showed higher correlation with operation time,operation charge and hospitalization expenses than MFISS and MISS,and it could distinguish single and multiple mandible fractures effectively.It was also a significant factor affecting the cost of hospitalization.Conclusion:The Mandible Injury Severity Score was more suitable for the scoring of mandible fracture.

Objective To investigate the effects of transplantated tumor capillary permeability under microbubble enhanced diagnostic ultrasound exposure.Methods Fourty eight rats were randomly divided into four groups after Walker 256 carcinomas were subcutaneousely implanted,named the control group (A),microbubbles group (B),ultrasound group (C),microbubbles and ultrasound group (D).Using Evans blue(EB) as the indicator for tumor capillary permeability,the microbubbles were injected through the vein with diagnostic ultrasound frequency as 1.75 MHz,mechanical index as 1.4.The spillover of EB was estimated under confocal laser microscope,meanwhile the contents of EB in the tumor tissues were calculated according to the standard curve and spectrophotometry.Results EB spillover was observed around the capillaries in the group D,while EB spillover was only observable on capillary in group A,B and C.The EB content was also significantly higher than those in group A,B and C.Conclusions Exposure to both diagnostic ultrasound and microbubbles results in increased capillary permeability of rat tumor tissues,which might become a potential therapeutic method on clinical chemotherapy.

Objective:To review and compare the clinical features and treatment outcomes of oral and maxillofacial space infection (OMSI)between diabetic and non-diabetic patients.Methods:Clinical data of 43 diabetic patients with OMSI(simultaneoustly treated by blood sugar control)and 84 of non-diabetic patients with OMSI were reviewed,the clinical features and treatment outcomes were compared.Statistical analyses were conducted by T test,the chi square test and variance analysis.Results:Diabetic patients with OM-SI were older(P =0.000),had more spaces involved concurrently(P =0.035 )and had higher blood sugar at presentation(P =0.000).There was no significant difference between groups about the use and change of antibiotics,the incision times,hospital stay durition and the incidence of the complications.Conclusion:The prognosis of the diabetic patients with OMSI under the strict control of the blood glucose concentration has no significant difference from the non-diabetic patients with OMSI.Diabetic patients with OMSI have older age and more spaces involved,and special attention should be paid.

Objective To investigate whether the surgery resorting to computer-assisted navigation system (CANS) can enhance effects in managing unilateral old zygomatic complex (ZMC) fracture in comparison with conventional surgery.Methods Twenty-four patients with unilateral old ZMC fracture for which surgical correction was wanted were divided into study group (n =12,treated with navigational surgery) and control group (n =12,treated with traditional surgery) in the 1 ∶ 1 matched case-control study.Therapeutic effects of CANS were evaluated by postoperative CT measurement,subjective satisfaction questionnaire and clinical examination.Results According to postoperative three-dimensional CT measurement,the mean projection and width differentials of bilateral zygomatic bones were 1.58 mm and 1.47 mm in study group,3.58 mm and 3.63 mm in control group,with significant differences between groups.No complications occurred within three months of follow-up.Moreover,the patients in study group were all satisfied with the treatment,but two patients in control group desired further surgery to ameliorate zygomatic shape.Conclusion Surgery with application of CANS improves efficacy of treatment for unilateral old ZMC fracture.

Objective To evaluate therapeutic effects and complications of concurrent three-dimensional conformal radiotherapy (3DCRT) and chemotherapy in patients with limited-stage small cell lung cancer (LSCLC).Methods From June 2000 to August 2005, 93 histologically proved LSCLC patients were randomized into two groups:3DCRT group (n =46) and conventional group (n =47).In both groups, patients received one cycle chemotherapy, followed by concurrent chemoradiotherapy and then received consolidate chemotherapy.Chemotherapy was four to six cycles of PE regimen.Conventional irradiation field was setup in conventional group, while in 3 DCRT group clinical target volume (CTV) only involved visible tumor and adjacent lymphatic region.Radiotherapy was delivered at 2 Gy per fraction, 5 fractions per week to a median total dose of 60 -64 Gy.Those who achieved a complete response were treated with prophylactic cranial irradiation (PCI) with 30 Gy in 10 fractions.Results The follow-up rate was 100% in both groups.The number of patients completed 1-, 2-and 3-year follow-up were 36, 34 and 16 in 3DCRT group, 14, 7 and 8 in conventional group, respectively.The complete and overall response rate were 52% and 89% in 3DCRT group, while 47% and 85% in conventional group, respectively.The 1-, 2-and 3-year survival rates were 78%, 35% and 15% in 3DCRT group, 72%, 30% and 17% in conventional group, respectively.The median survival time was 23.2 and 22.8 months, respectively.There was no statistical difference in short-term (Χ~2 = 0.34 ,P = O.759) and long-term outcomes (Χ~2 = 0.18 ,P = 0.92).In 3DCRT group, the incidence of grade 1 +2 acute radiation pneumonitis and esophagitis, grade 1 +2 and grade 3 chronic radiation pneumonitis were lower than those in conventional group.There was no grade 3 or 4 acute radiation pneumonitis or esophagitis, or grade 4 chronic radiation pneumonitis in both groups.There was no difference in grade 1 + 2, grade 3 or grade 4 acute myelo-suppression between the two groups.Conclusions In the treatment of LSCLC, concurrent 3DCRT and chemotherapy can achieve satisfactory short-term and long-term outcomes with acceptable complications.

Objective To investigate the role of clinical pharmacists in the standardized management of the antimicrobial drugs.Methods The medical records of 64 patients with clinical pharmacist intervention after the treatment in January 2012 to June 2012 were set as control group.The medical records of 64 patients with clinical pharmacist intervention before the treatment in July 2012 to April 2013 were set as the observation group , the efficacy and safety of anti -infection treatment of the two groups pa-tients were compared.Results The observation group total the anti -in-fection treatment efficiency , recovery time , hospitalization time , the inci-dence of adverse reactions , irrational use of antibiotics of the observation group were also better than those of the control group , the difference was statistically significant ( P<0.05).Conclusion Establish and perfect the clinical pharmacists involved in the rational use of antimicrobial agents in the management system and standardized operating modes for rational drug use played a positive role.

Objective To study the application value of laparoscopic curettage in the standardized training for residents.Methods In this study,we selected residents of the Wuhan First Hospital as the research subjects.Thirty of the subjects from the 2015 grade were the control group and another 29 from the 2016 grade were the experimental group.Both groups had three classes,including one theory class,and two practice classes.After the theoretical class,the experimental group practiced laparoscopic curettage,while the control group practiced curettage.After practice,the experimental group filled out the questionnaire on teaching quality,and both groups participated in the theory test.Results Laparoscopic curettage can significantly improve students' ability to learn and understand curettage,so that most students can adapt to curettage,eliminate the panic from uterine perforation and be more sensitive to the uterus textures,and satisfactory teaching results were achieved.The average score of the practice test for the experimental group (9.150 ± 2.461) was statistically higher than that for the control group (7.053 ± 1.347).The average score of the theory test (7.581 ± 1.632) for the experimental group was not statistically different from that for the control group (6.983 ± 1.726).The average scores of the two tests for the experimental group (9.037 ± 1.951) and the control group (6.891 ± 2.140) were statistically different.Conclusions Laparoscopic curettage can significantly improve the ability to learn,understand and feel curettage for residents who are under standardized training,and it has great application value in the three basic operation trainings.
