Objective To compare the clinical features of space infections in the oral maxillofacial region between patients with diabetes mellitus and patients without diabetes.Methods A retrospective study was conducted on 61 patients diagnosed with space infections in the oral maxillofacial region and receiving treatment at the department of oral and The 4nd Affiliated Hospital of Kunming Medical University between 2013 and 2016.The patients were divided into 2 groups:diabetic group (n =28) and non-diabetic group (n =33).The study variables were demography,etiology,clinical and laboratory examinations (bacteriology,admission blood glucose level,admission white blood cell count and percent of neutrophil on admission).The outcome was compared.The length of hospital stay and complications were also compared.Statistical analyses of the results between groups were performed using the t test and chi square test.Results For oral and maxillofacial space infection,there was no statistically significant difference in gender between the diabetic group and (28 cases) and non diabetes group (33 cases) (x 2 test,P=0.5929);while there were statistically significant differences between two groups in age (t test,P＜0.001) and in the number of infection space (t test,P＜0.001);there was no significant difference between the two groups in the sources of infection (x 2,P＞0.05);The main source of infection was odontogenic,followed by adenogenous.There were statistically significant differences between two groups in blood glucose concentration at admission (t test,P＜0.001) and in the hospitalization time and complications (t test and x 2 test P＜0.05),while no statistically significant differences in the white blood cells count and neutrophil count (t test,P＞0.05).Compared with the non diabetic group,for patients in the diabetic group,the age of onset was older,the involvd gaps were more,the blood glucose concentration was higher on admission,the length of stay was longer,complications were more likely to occur,and the consequences were more serious.Conclusion Compared with non diabetes group,space infection in oral and maxillofacial region is more serious and the hospital stay is longer and has more complications in diabetic patients which should be paid higher attention to.

Objective To investigate surgical techniques and results of arthroscopic reduction and fixation for the treatment of avulsion fracture of the posterior cruciate ligament from the tibia through an additional posterolateral portal. Methods An additional posterolateral portal was established by using the inside-out technique under arthroscopic view.After a protective sleeve was placed through the portal and the displaced fracture was reduced,the fragment was fixed by the guide wire drilled through the sleeve temporarily.If the fluoroscopic control showed an anatomic reduction of the fragment and good placement of the wire,the self-attacked cannulated screw and washer was placed intra-articularly over the guide wire through the sleeve for the directive internal fixation of the avulsion fracture.Aggressive rehabilitation programs were recommended postoperatively.Results Except 1 case with 11 mm displacement and rotation of the fragment treated by the arthrotomy after the failure of arthroscopic reduction,the arthroscopic operation was accomplished in all the remaining 10 cases.The operative time was 63～98 min(mean,87.3 min).No injuries of popliteal vessels or nerves occurred.The postoperative X-ray firms showed an anatomic reduction of the fragment and good placement of the screw and washer.With the negative posterior drawer test confirmed by the physical examination,normal range of motion of the injured knee joint and gait were achieved in the 10 patients at 4～7 weeks after surgery.The bone union was confirmed by X-ray films at the 3 months postoperatively.The computer KT-2000 arthrometer measurements of posterior tibial displacement of both knee joints showed side-to-side difference not more than 1.2 mm in 6 patients at 5 months after surgery.Conclusions The additional posterolateral portal can be established by the arthroscopic inside-out technique safely.The displaced fragment of the avulsion fracture of the posterior cruciate ligament from the tibia can be reduced and fixed with the self-attacked cannulated screw and washer arthroscopicly.

Objective To investigate the function of donor-derived dendritic cells (DCs) treated with NF-?B decoy in prolonging murine cardiac allograft survival time.Methods Donor bone marrow- derived DCs were treated with NF-?B decoy in vitro.Heterotopic abdominal heart transplantation was performed from BALB/c to C57BL/6 mice.Recipients were grouped according to different pretreat ments as follows:(1) Control group,infusion of PBS (0.2 ml) alone intravenously via the portal vein 7 days before heart transplantation;(2) CsA group,treated with sub-therapeutic CsA only for 7 days (10 mg?kg~(-1)?day~(-1)) through intraperitoneal injection after transplantation,and the same as control group before transplantation;(3) Control DCs group,infusion of only cultured 5th-day recipient DCs untreated with NF-?B ODN decoy;(4) Treated DCs group,infusion of recipient DCs pretreated with NF-~cB ODN decoy;(5) Combined treatment group,infusion of recipient DCs treated with NF-~cB ODN decoy before transplantation and intraperitoneal injection of sub-therapeutic CsA for 7 days (10 mg?kg~(-1)?day~(-1)) after transplantation;(6) Third party donor group,C3H/HeJ mice used as donor, and recipient (C57BL/6) was treated the same as combined treatment group.Every group had 8 mice and graft survival time was observed.Cytokines (IL-2,INF-?,IL-4 and IL-10) in recipient serums were analyzed by ELISA at 7th day after transplantation.Results The graft mean survival time (MST) in control group,CsA group,Control DCs group,treated DCs group,combined treatment group and third party donor group was 7 days,10.3 days,7.6 days,21.4 days,53.6 days and 9 days,respectively.There was significant difference in MST between treated DCs group and control group or control DCs group (P

BACKGROUND: Myogenic regulatory factors Myf-5 is an importance gene involved in muscle occurrence process to adjust and control, start and maintain the skeleton muscle cell growth. It has a possible relation with denervated skeletal muscle atrophy. OBJECTIVE: To detect the expression of Myf-5 gene in different skeletal muscle sitas and different periods following denervatad skeletal muscle atrophy.DESIGN, TIME AND SE'I-rlNG: Randomized control animal experiment was performed in the Shanxi Medical University between March and April in 2008. MATERIALS: A total of 24 Sprague-Dudley male rats was selected and divided randomly into four groups, with six in each, Le. sham operated group (innervations), denervated 2 d group, denarvated 7 d group and denervatad 28 d group. METHODS: Sham operations were made only for the rats in the sham operated group and sciatic nerve were not cut off. Sciatic nerves were cut off more than one centimeter at the mid-level of their right lower limb for the rats in denervated groups. The rats were executed by vertebrae dislocation method at 2, 7, 28 days after denervation. The skeletal muscles of the right lower limb (tibialis anterior, soleus, gastrocnemius and plantar) were dissected and dissociated. MAIN OUTCOME MEASURES: Myf-5 mRNA expression was detected by reverse transcription-polymerase chain reaction. Immunohistochemical stain (ABC method) with polyclonal antibody against Myf-5 protein was performed and the gray value was counted.RESULTS: Expressions of Myf-5 mRNA in denervatad skeletal muscle were up-regulated at 2, 7, 28 days in the eady stage of denervation (P < 0.05). The number of Myf-5 antibody positive-stained cell nuclei was the most in satellite cells at 28 days following denervation. CONCLUSION: At the early stage of denervated skeletal muscle atrophy in SD rats, expressions of Myf-5 in different skeletal muscles are all up-regulated. Denervation of rat skeletal muscle raises the Myf-5 expression in satellites cells.

BACKGROUND: MyoD expression of skeletal muscle of rats increases distinctly in the earlier period of denervation, which can greatly postpone denervated skeletal muscle atrophy. The clinical test testifies that electrical stimulation is an effective method to cure denervated muscle atrophy. But the influence of electrical stimulation on MyoD expression during denervated muscle atrophy is still unproved. OBJECTIVE: To discuss the influences of electrical stimulation on the gene expression of MyoD of skeletal muscle of rats. DESIGN, TIME AND SETTING: Randomized control animal experiment was performed in the Animal Experimental Center of Shanxi Medical University between July and November in 2008. MATERIALS: A total of 36 healthy Sprague-Duwley rats of either gender were divided randomly into three groups, control group, denervation group and electrical stimulation group. Each group contained 12 rats. METHODS: Standard models of right sciatic nerve dissociation and gastrocnemius denervation were established in right limb of each rat in denervation group and electrical stimulation group. Thirty-minute electrical stimulation was given to the denervated gastrocnemius muscle of each rat of electrical stimulation group once a day. The rats were executed at 2, 7, 14, 28 days after denervation to dissect and dissociate their gastrocnemius muscles of the right lower limbs. MAIN OUTCOME MEASURES: MyoD mRNA expression was detected by reverse transcription polymerase chain reaction, and MyoD protein level by immunohistochemistry. RESULTS: The expression of MyoD mRNA and MyoD protein level in specimens of denervation group and electrical stimulation group were up-regulated at 2, 7, 14, 28 days after denervation, with significant differences compared with blank control group (P

Objective To investigate the effect of mixed-skin grafting with autologous microskin and allogenetic acellular dermal matrix microskin on wound healing in rats,and to make a further study on the related mechanism.Methods Wistar rats were served as a allogenetic acellular dermal matrix donor rats,and SD rats as acceptors with mould of full thickness skin defects on their back.The ninety SD rats were divided into 5 groups with 18 rats in each group.Group 1 was transplanted with autologous microskin,and group 2 with allogenetic acellular dermal matrix microskin.Groups 3,4 and 5 were grafted with mixed-skin ratio between autologous microskin and allogenetic acellular dermal matrix microskin 1 ∶ 1,1 ∶ 0.5 and 1 ∶ 0.25,repectively.The rate of wound healing was measured,wound samples collected,hematoxylin and eosin stain carried out,fibronectin (FN) and laminin (LN)detected,and intergroup comparison made,respectively,2,3 and 4 weeks after skin grafting.Results The wound healing rates and FN and LN expression of mixed-skin grafting groups were higher than those of the group with autologous microskin grafting.The group of 1 ∶ 0.25 obviously increased (P＜0.05 or P＜0.01).Conclusions The wound healing rate with mixed-skin grafting is higher than that with autologous microskin grafting.The best effect is achieved when the skin ratio between autologous microskin and allogenetic acellular dermal matrix microskin is 1 ∶ 0.25.It is possibly due to the increase of FN and LN on wound skin surface.

Objective To estimate and compare the equivalent dose between the intensity modula-ted radiotherapy (IMRT) and conventional radiotherapy (CR) for patients with nasopharyngeal carcinoma (NPC). Methods The peripheral equivalent dose of NPC patients was measured by TLD during IMRT and CR. The whole-body equivalent dose was calculated. Results When prescribed tumor dose of 70 Gy was given, the mean number of accelerator output units were 25235 MU and 8575 MU, and the whole-body e-quivalent dose were 73.65 mSy and 15.28 mSy for IMRT and CR, respectively. Conclusion The equiva-lent dose in IMRT is 4.8 times higher than that in CR for patients with nasopharyngeal carcinoma.
