Objective To investigate the surgical correction of alar deformity and repairing function of unilateral cleft lip in infant. Methods Millards procedure was used to incise skin, muscle and mucosa, correct the nasal deformity through lip. At the normal side, ophthalmic scissors was applied to incise lips muscle and skin, and reach the deep level of the base of nasal pillor, cut the abnormal attachment between the orbicular muscle of mouth and anterior nasal spina, and sharp dissect cartilage and skin in nasal wing through deep level of nasal pillor. At the cleft side, the abnormal muscle branch was cut that attached at the down side of the base of nose and pyriform aperture, the tissue between nasal base and lip, maxilla relaxed, and the cartilage and skin in the nasal wing at the same side dissected. The deform cartilage was repairied as the same of normal side. After the rehabilitation of cartilage of nasal wing, the soft tissue at deep level was moved to normal location, but the deep level structure of nasal wing cartilage, nasal septum cartilage and nasal bone did not dissected. After the dissection of orbicular muscle of mouth, the muscle in nose and lip must be relaxed in illous side. The orbicular muscle of mouth was sewed under the condition of tensionless. The repairing of orbicular muscle of mouth will improve the balance of muscular strength around the nose. Thus, the deviation of nasal pillor was corrected and the base of nose repaired. Results Eighty cases of infant with unilateral cleft lip at the age of 3 months ～12 months, in which 11 cases were Ⅰ?,16 Ⅱ, and 3 Ⅲ?. Eighty cases were low grade alar deformity, and 13 middle grade deformity. After operation, 52 cases were better, 17 cases were good, and 11 cases were worse. The postoperational result was good. Conclusion While performing the cleft lip operation or Millard operation, the authors can correct the nasal deformity through lip. So, it is recommended that cleft lip and the alar deformity can be repaired at the same time.

Objective The purpose of this study was to evaluate the outcome of autogenous bone grafts in unilateral cleft lip and palate patients following early orthodontic tooth movement,and to determine the volume of new bone formation in the bone grafted region with spiral computed tomography.Methods Computed tomography scans of 12 patients were taken immediately preoperatively and at 6 months postoperatively.The patients underwent bone grafting between 9 and 13 years of age were divided into two groups based on whether postoperative orthodontic tooth movement were initiated or not.Three-dimensional models were created in each period,and the defect of alveolar cleft and volume of the newly formed bone were calculated in each patient.The roots of the moved teeth and their positions to the alveolar bone were also observed.Results The preoperative cleft width and cleft volume were not significantly different between both groups.The volume of the newly formed bone in group A was (0.98±0.23) mm3,significantly higher than that in group B,which was (0.73± 0.15) mm3.The rate of newly formed bone in group A was (72.5 ± 11.9)％,significantly higher than that in group B,which was (53.2±9.7)％.The cleft adjacent teeth could move smoothly into the bone grated area,with no root resorption observed in the computed tomography scans.Conclusions Early orthodontic tooth movement can reduce bone resorption in autogenous bone grafted unilateral cleft lip and palate patients through the observation of spiral computed tomography.It plays an active role in the bone remolding process after bone grafting.

BACKGROUND: The neurotoxicity and cardiotoxicity of bupivacaine have been reported frequently. However, the studies on bupivacaine-induced muscle toxicity are few.
OBJECTIVE: To establish and evaluate local intramuscular injection of bupivacaine on the changes in histomorphology and ultrastructure of rat multifidus muscle at various time points.
METHODS: A total of 54 male Sprague-Dawley rats weighing 280-320 g were randomly divided into black group (n=18), model group (n=18) and model control group (n=18). Each group was then equal y subdivided into three subgroups according to time points (4, 7 and 14 days) (n=6). Both sides of multifidus muscle of the rats (L4 and L5) were injected with 0.5% bupivacaine. The morphological and ultrastructural changes of multifidus muscle were observed and analyzed with light microscope and transmission electron microscope at 4, 7 and 14 days after model establishment.
RESULTS AND CONCLUSION: (1) A single intramuscular injection of 0.5% bupivacaine induced muscular damage. (2) Hematoxylin-eosin staining results showed fiber necrosis, inflammatory cel infiltration, and a smal amount of macrophages in local skeletal muscle. (3) Under the transmission electron microscope, the structure of myofibrils was destroyed or disintegrated; kinds of bands and lines were indistinct, disrupted or disappeared; the structure of mitochondria was abnormal, the mitochondrial cristae were reduced or disappeared. In the 7- and 14-day groups, multifidus muscle proliferated and repaired. (4) Ultrastructural change scores in skeletal muscle were significantly higher in the model group than in the blank and model control groups (P < 0.05). Above scores were significantly greater in the 4-day group than in the 7- and 14-day groups (P < 0.05), and higher in the 7-day group than in the 14-day group (P < 0.05). (5) Results suggest that a single intramuscular injection of 0.5% bupivacaine can result in pathological changes of skeletal muscle from morphology and ultrastructure. This method can establish a suitable model of skeletal muscle injury.

Conclusions Cigarette smoking status, radiation dose, gross tumor volume and clinical stage are significant prognostic factors on survival in patients with Stage Ⅲ NSCLC treated with RT based on PET-CT radiotherapy planning.

OBJECTIVETo observe the effect of Xuefu Zhuyu decoction on serum asymmetric dimethylarginine (ADMA) level of the atherosclerosis rabbits.

METHODTwenty-four male rabbits were randomly divided into three groups: control group (n = 8) was fed with normal diet; the model group (n = 8) was fed with high fat/high cholesterol diet; and Xuefu Zhuyu decoction group (n = 8) was fed with high fat/high cholesterol diet and intragastric administrated with Xuefu Zhuyu decoction 7.10 g x kg(-1) x d(-1). Concentrations of serum total cholesterol (TC), total triglyceride (TG), low density lipoprotein (LDL), serum ADMA and serum nitric oxide (NO) were measured after eight weeks. Rabbits' aorta were made into the pathological section to observe the pathology changes degree and atherosclerotic plaqu mean gray value and plaque area were analyzed by OPTIMAS image analysis system.

RESULT1) Compared with the aortic atherosclerotic plaqu mean gray value of Xuefu Zhuyu decoction group 175.56 +/- 12.30, those of the model group 198.91 +/- 5.08 were significant higher (P < 0.01). Significant difference were found between the the aortic atherosclerotic plaque area of the model group (4.80 +/- 0.83) mm2 and Xuefu Zhuyu decoction group (1.96 +/- 0.48) mm2 (P < 0.01). There were no atherosclerotic plaque in the control group rabbits' aorta. 2) The serum TC (23.42 +/- 7.80) mmol x L(-1), TG (2.37 +/- 0.42) mmol x L(-1) and LDL (17.24 +/- 8.29) mmol x L(-1) of the model group were higher than those of Xuefu Zhuyu decoction group (P < 0.01); Compared with control group, the serum TC (15.63 +/- 4.12) mmol x L(-1) and LDL (7.64 +/- 2.36) mmol x L(-1) of the Xuefu Zhuyu decoction group increased significantly, while there were no significant changes between serum TG of control group (1.11 +/- 0.26) mmol x L(-1) and serum TG of Xuefu Zhuyu decoction group (1.43 +/- 0.34) mmol x L(-1). The serum ADMA of the model group (1.57 +/- 0.17) micromol x L(-1) were higher than those of Xuefu Zhuyu decoction group (1.01 +/- 0.13) micromol x L(-1) (P < 0.01), while the serum NO of the model group (8.76 +/- 2.42) micromol x L(-1) were significantly lower than those of Xuefu Zhuyu decoction group (15.90 +/- 2.38) micromol x L(-1) (P < 0.01). There were no significant difference between the serum ADMA of the control group (0.93 +/- 0.11) micromol x L(-1) and Xuefu Zhuyu decoction group. Compared with Xuefu Zhuyu decoction group, the serum NO of the control group (17.88 +/- 3.34) micromol x L(-1) have no significant difference. 3) The serum ADMA of all rabbits negatively correlated to the serum NO (r = -0.773), (P < 0.01).

CONCLUSIONXuefu Zhuyu decoction can decrease the serum ADMA level in atherosclerosis rabbits. The effect of Xuefu Zhuyu decoction on anti-atherosclerosis may be related to the decreased serum ADMA level.

Periodontitis is a chronic periodontal disease with a high incidence, and chronic obstructive pulmonary disease (COPD) is considered to be a chronic airway inflammatory disease. In recent years, many studies have observed that there is a potential relationship between periodontitis and COPD. The periodontal condition of patients with COPD is relatively poor, and the composition of their oral microbiome is different from that of healthy people. The inflammation “spillage”and hypoxia may induce the occurrence and development of periodontal disease. At the same time, the risk of COPD in periodontitis patients may be related to the inhalation of periodontal pathogens and inflammatory factors. Regular periodontal sequence therapy can reduce the risk of acute exacerbation of the disease to a certain extent. Since periodontitis and COPD are both chronic progressive diseases characterized by chronic inflammation and accompanied by proteolytic destruction of connective tissue, they may share a common pathophysiological process and may be intrinsically linked. This article reviews the latest research progress on the relationship between chronic periodontitis and COPD, and possible interaction mechanism, in order to provide insight for further study on the interaction between the two conditions.

OBJECTIVETo Verify the safety and reliability of one-stage repair of complete cleft Lip and palate in infancy and to obtain the primary result.

METHODSThe simultaneous repair of complete cleft Lip and palate in infants 3 to 12 months of age were performed in 271 cases. The deformities include 185 cases of typical complete unilateral clefts and 75 cases of complete bilateral clefts, and other 11 atypical cleft infants. The preoperative orthopedic treatment for wide alveolar cleft was undertaken in 24 infants and the lip appearance and speech outcome were evaluated in 116 children by 1 to 4 years' postoperative follow-up.

RESULTSAll infants, except for dyspnea in 2 babies, palatal fistula formation in 6 cases and temporary wound hemorrhage in 5 infants, were recovered without complications. After orthopedic treatment, the width of the alveolar cleft was reduced 6.1 mm in average. The evaluation showed that 93.1% of children had got good or excellent lip appearance. And the acceptable or excellent speech was found in 94.8% children.

CONCLUSIONSSimultaneous repair of complete cleft lip and palate in infancy is safety and reliable. The preoperative orthopedic procedure is able to reduce the wide alveolar cleft and to achieve alignment of alveolar segments. The acceptable and or excellent lip appearance and speech function could be obtained in this one-stage operative procedure in infants.
